In order to at least partially solve the problems in the prior art, some embodiments of the present utility model provide a water purifying and drinking machine having a water intake, the water purifying and drinking machine including a tap water intake, a raw water tank including a water tank water passing port, a water inlet control valve having a water inlet connected to the tap water intake through a water intake pipe and a water outlet connected to the water tank water passing port, a water purifying assembly including a raw water inlet, a purified water outlet and a concentrate outlet, the raw water inlet being connected to the water tank water passing port, the purified water outlet being connected to the water intake, a water outlet being connected to the outside, the concentrate outlet being connected to the water outlet through a first concentrate pipe, and a water level detecting assembly for detecting a water level in the raw water tank, the water inlet control valve being closed when the water level is higher than or equal to an upper limit of the water level.

In the case of a clean water dispenser of the commercial type, the cartridge may be a high flux reverse osmosis cartridge. When a large amount of water is taken, the raw water tank may first provide a source of water. Only after the water in the original water tank is used up, the condition that water is supplied by the tap water pipe only can occur. When the water in the original water tank is used, the tap water pipe can also supplement tap water to the original water tank, so that the user requirement can be met generally. Under the condition that the water purifying and drinking machine is household, the filter element can adopt a large flux reverse osmosis filter element or a small flux reverse osmosis filter element. When the water is stopped, the water stored in the raw water tank in advance can be supplied to a user after being filtered.

It is easy to understand that if the valve assembly is not provided, raw water in the raw water tank may enter the first concentrate line through the second concentrate line and flow out of the drain port in the case that the first concentrate line is conducted. The valve assembly is arranged to only allow the concentrated water to flow out of the water outlet, so that the raw water is prevented from leaking out of the water outlet.

For example, the first concentrate line may be cut off. Through making first dense water pipeline stop, can be with clean drink machine from dense water through outlet discharge switch into dense water and return former water tank, can be applicable to various application scenarios, the model and the kind of clean drink machine can standardize to change by oneself according to user's service environment.

The water purifier further comprises a blocking piece for opening or closing the water outlet, and the first concentrated water pipeline is blocked when the blocking piece closes the water outlet. Therefore, the switching of the mode of discharging the concentrated water of the water purifying and drinking machine can be realized through lower cost without control.

Therefore, a user does not need to plug the water outlet through the plug or the cover body, the problem that the plugging piece is lost is avoided, and the problem that the plugging piece is tethered on the water purifying and drinking machine through a rope to influence the beauty is avoided.

The valve assembly includes one or more of a first check valve disposed on the second concentrate line, the first check valve configured to be unidirectionally conductive in a direction opposite to the predetermined direction, a second concentrate valve disposed on the second concentrate line, and a switching valve including a valve water inlet, a first valve water outlet, and a second valve water outlet, the valve water inlet being communicated to a concentrate outlet of the water purification assembly, the first valve water outlet being communicated to a water inlet of the second concentrate line, the second valve water outlet being communicated to a water inlet of the first concentrate line. Through controlling the switching valve, the concentrated water can be controlled to be discharged to the water outlet or the concentrated water is controlled to flow back into the original water tank, and a plugging piece or a first concentrated water electromagnetic valve is not required to be arranged at the moment.

The water purifying and drinking machine comprises a water quality detection assembly, a prompting device and a controller, wherein the water quality detection assembly is used for detecting water quality in a raw water tank, and the controller controls the prompting device to send prompting information when the water quality does not reach the standard. Therefore, the service life of the filter element can be prolonged under the condition that the water source with poor water quality is used in the water purifying and drinking machine.

Illustratively, the raw water tank is not detachable. The raw water tank can be protected by the shell.

The water purifying and drinking machine comprises a water level detection assembly, a prompting device and a controller, wherein the water level detection assembly is used for detecting the water level in a raw water tank, and the controller is used for controlling the prompting device to send out prompting information when the water level is lower than or equal to the lower limit of the water level. The prompting device can prompt a user to replace water in the original water tank in time so as to ensure that the water source of the water purifying and drinking machine is sufficient.

The water purifying and drinking machine further comprises a tap water port, a water inlet control valve, a water outlet and a water level detection assembly, wherein the water inlet of the water inlet control valve is communicated to the tap water port through a water inlet pipeline, the water outlet of the water inlet control valve is communicated to the water tank water passing port, the water level detection assembly is used for detecting the water level in the raw water tank, and the water inlet control valve is closed when the water level is higher than or equal to the upper limit of the water level. Therefore, the water supplementing of the raw water tank can be controlled at low cost through a simple structure. Due to the existence of the raw water tank, the water purifying machine can still provide purified water required by a user for a period of time through raw water stored in the raw water tank under the condition of water cut-off.

The water purifying and drinking machine further comprises a second one-way valve arranged on the water inlet pipeline, and the second one-way valve can be communicated unidirectionally along the direction from the tap water port to the raw water inlet of the water purifying component.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

The embodiment of the utility model provides a water purifying and drinking machine. A water purifying dispenser according to an embodiment of the present utility model will be described in detail with reference to the accompanying drawings.

As shown in fig. 1, the water purifying dispenser may have a water intake 10, and the water intake 10 may be formed of a water outlet 20 or a tap provided on the water purifying dispenser. The water purifying dispenser may include a tap water port 80 and a raw water tank 100, the tap water port 80 may be connected to a municipal pipe network, a user's tap water tap, etc. through a pipe, thereby obtaining tap water. The raw water tank 100 is used for storing raw water, which is usually tap water from the tap water port 80. The water purifier may further include a water purification assembly 200, the water purification assembly 200 including a raw water inlet 201 and a purified water outlet 202. The water purification assembly 200 may filter raw water entering the raw water inlet 201 and provide purified water from the purified water outlet 202. Illustratively, the raw water tank 100 may be detachable, which a user may detach and replenish raw water therein. In this case, the raw water tank 100 may include a water filling port (not shown), through which a user may supplement raw water into the raw water tank 100. Raw water may include, but is not limited to, barreled water, well water, or tap water.

Illustratively, the raw water tank may also be non-removable, for example, a commercial clean water dispenser, where the raw water tank is typically non-removable and may be embedded within the interior of the clean water dispenser. The raw water tank can be protected by the shell. The raw water tank 100 may include a water tank through-port 101, and the water tank through-port 101 may communicate with the raw water inlet 201 to supply raw water to the water purification assembly 200. In some embodiments below, the tank water inlet 101 may also be used to receive raw water. The water tank crossing port 101 may be provided at the bottom of the raw water tank 100 so that most of raw water in the raw water tank 100 may flow out of the raw water tank 100 through the water tank crossing port 101. In an embodiment not shown, a water tank crossing port may be provided at an upper portion of the raw water tank, from which raw water may be extracted through a pipe inserted from the water tank crossing port to the raw water tank. Alternatively, the water tank crossing port may include a first water tank crossing port, which may be connected to the raw water inlet 201 of the water purification assembly 200, and a second water tank crossing port, which may receive raw water.

With continued reference to fig. 1, the water purification assembly 200 may include a filter cartridge 210, and the filter cartridge 210 may include a filter cartridge such as an activated carbon filter cartridge, a PP filter cartridge, a ceramic filter cartridge, a resin filter cartridge, an ultrafiltration filter cartridge, a nanofiltration filter cartridge, a reverse osmosis filter cartridge, and the like, as well as a composite filter cartridge composited from one or more of the filter cartridges. Taking the example of filter element 210 comprising a reverse osmosis filter element, the pore size of the reverse osmosis filter element is one hundred thousandth (0.1 nanometer) of that of hair, and bacteria and viruses which cannot be seen by naked eyes are typically 10 times as large. Therefore, only water molecules and part of mineral ions beneficial to human bodies can pass through, other impurities and heavy metals are discharged from the concentrated water outlet, and high-quality purified water is provided for users. For nanofiltration cartridges as well as reverse osmosis cartridges, an appropriate pressure is required during their operation, so the water purification assembly 200 may further comprise a booster pump 220. The nanofiltration filter cartridge and the reverse osmosis filter cartridge also produce a proportion of concentrate during operation, so that the water purification module 200 comprising either or both is also provided with a concentrate outlet 203. The concentrate outlet 203 is connected to a concentrate inlet of the cartridge 210 through a concentrate proportional valve 230. The concentrated water proportional valve 230 is in a closed state, so that the pressure required by the normal operation of the filter element 210 can be maintained, and the raw water can quickly pass through the filter element 210 and the concentrated water proportional valve 230 when the concentrated water proportional valve 230 is in an open state, so that the filter element 210 is washed. The filter element 210 can filter raw water, thereby removing harmful bacteria, heavy metals and other impurities therein and providing high-quality purified water for users.

Since the raw water in the raw water tank 100 has almost no pressure, the booster pump 220 is provided to pump and pressurize the raw water from the raw water tank 100 to increase the output flow rate of the purified water. The clean water outlet 202 may be connected to the water intake 10 to provide clean water to the user. The cartridge 210 may employ a large flux reverse osmosis cartridge or a small flux reverse osmosis cartridge. The daily water yield of the large flux reverse osmosis filter element is not less than 400 gallons. Under the condition that the filter element 210 adopts a low-flux reverse osmosis filter element, the clean water tank 31 and the water pump 32 can be further arranged on the clean water waterway 30 between the clean water outlet 202 and the water intake 10, so that water can be continuously prepared and the clean water tank 31 can be replenished when a user does not get water, and the user experience is prevented from being affected by water flow when the user gets water. For the embodiment shown in fig. 1, clean water tank 31 and/or clean water outlet 202 may also be connected to cold bladder 40, ice making assembly 50, heating assembly 60, etc. via piping to produce cold water, ice cubes, and hot water, respectively, to meet the needs of the user's diversity. The water purifying dispenser may include a water outlet 70, the water outlet 70 may be in communication with the outside, and the concentrate outlet 203 may be in communication with the water outlet 70 through the first concentrate line 300. Specifically, for example, the drain port 70 may be connected to a drain pipe, which may be connected to a sewer or a container for receiving concentrated water. The user can use the concentrate in the container for various purposes if desired.

The water purifying dispenser may include a water inlet control valve and a water level detection assembly for detecting a water level in the raw water tank, and a water inlet of the water inlet control valve 500 is communicated to the tap water port 80 through a water inlet pipe 600. The water outlet of the water inlet control valve 500 is communicated to the water tank water passing port 101. In case the water purifying dispenser is connected to tap water, the original water tank 100 may be replenished with the connected tap water in case the water level in the original water tank 100 is low. The water purifier may further include a water level detection assembly that may be used to detect the water level in the raw water tank 100. For the above-described water purifying dispenser having the tap water port 80, the raw water tank 100 may be non-detachable, and the concentrated water is directly discharged to the outside through the water outlet 70 without entering the raw water tank 100. Illustratively, the water inlet control valve 500 may be a mechanical valve such as a float valve, and the water level detection assembly may be a float to which the float valve is connected. When the water level detection assembly detects that the water level is greater than or equal to the upper water level limit 104, the water inlet control valve 500 is closed. Thereby enabling low-cost control of the water replenishment of the raw water tank 100 through a simple structure.

In the above-described solution, as described above, the cartridge 210 may be a large flux reverse osmosis cartridge in the case of a clean water dispenser of the commercial type. When a large amount of water is taken, the raw water tank may first provide a source of water. Only after the water in the original water tank is used up, the condition that water is supplied by the tap water pipe only can occur. The tap water pipe supplements tap water to the original water tank 100 while using water in the original water tank, so that user's demand can be generally satisfied. In the case of a clean drinking machine for home use, the filter element 210 may be either a large flux reverse osmosis filter element or a small flux reverse osmosis filter element. When the water is stopped, the water stored in the raw water tank in advance can be supplied to a user after being filtered. When the tap water is recovered, the original water tank can be automatically filled.

As shown in fig. 2, the water purifying dispenser may further include a second check valve 601 provided on the water intake pipe 600, the second check valve 601 being unidirectionally conductive in a direction from the tap water port 80 to the raw water inlet 201 of the water purifying assembly. It will be readily appreciated that since the tap 80 may be located in any suitable location in the water purifying machine, the tap 80 may not be closed if there is no water source. The user supplies water using the original water tank 100. By providing the second check valve 601, even if the height of the tap water port 80 is lower than the liquid level in the raw water tank 100, raw water in the raw water tank 100 does not flow out from the tap water port 80. In other embodiments, the height of tap 80 is no lower than the top of original tank 100. In this way, even though the tap water port 80 may not be closed, raw water in the raw water tank 100 does not flow out from the tap water port 80.

Illustratively, the water purifying dispenser may further include a water level detection assembly, a prompting device, and a controller. The water level detecting assembly is used to detect the water level in the original water tank 100. The water level detection assembly may include one or more of any suitable sensor such as an infrared water level gauge, a float water level gauge, an ultrasonic water level gauge, or the like. The prompting device can comprise any prompting method such as voice prompting, lamplight prompting, short message prompting or APP prompting and the like, and can send prompting information to a user.

The controller can be built by adopting electronic elements such as a timer, a comparator, a register, a digital logic circuit and the like, or can be realized by adopting processor chips such as a singlechip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC) and the like and peripheral circuits thereof. The controller is used for controlling the prompt device to send out prompt information when the water level in the original water tank 100 is lower than the lower water level limit 103. In the event that tap water from the tap water port is interrupted or unconnected, the water purifier may employ only the raw water tank 100 as a water source. At this time, when the water level in the raw water tank 100 is lower than the lower water level limit 103, the user is required to manually supplement the raw water in the raw water tank 100. In this case, the prompting means may prompt the user to replenish the raw water. For commercial water purifying dispensers, for example, raw water tank 100 may be disposed inside the body and the water level may not be visible. The prompting device can prompt the user that the water source is interrupted, and the meaningless waiting of the user is avoided.

The following embodiments may be directed to a home-based water purifier. Illustratively, the raw water tank 100 is detachable, and the raw water tank 100 is configured to be injectable with raw water in a detached state. The water filling port of the original water tank 100 can be the same opening as the water tank water passing port 101, so that the number of openings on the original water tank 100 is reduced, and the structure is simpler. Of course, the filling port and the tank through port 101 may be different openings. By way of example and not limitation, the water filling port and the water tank water passing port 101 may be both provided below the raw water tank 100, and the water filling port may have a large opening and a cover, thereby facilitating the user's injection of raw water and preventing the raw water from being spilled. Alternatively, the pouring spout may be provided at the bottom of the raw water tank 100. Thus, the upper part of the original water tank 100 can be simpler, and the user experience is improved. The removable raw water tank 100 may be easily transported by a user to a water source location, such as a tap water location. For convenience of handling, a handle may be provided at the upper portion of the original water tank 100. The handle arranged at the upper part does not prevent the water filling port arranged below from filling raw water. The raw water tank 100 may be mounted to the water purifying dispenser after a sufficient amount of raw water is injected, and the tank water passing port 101 is connected to the raw water inlet 201 in a mounted state of the raw water tank 100, thereby supplying raw water to the water purifying assembly 200. The water tank crossing port 101 may be provided with a water stop valve (not shown) through which raw water cannot flow out in a disassembled state of the raw water tank 100, and through which raw water can reach the raw water inlet 201 to which the water tank crossing port 101 communicates in an installed state of the raw water tank 100.

Illustratively, as shown in fig. 3, the raw water tank 100 may further include a tank concentrate inlet 102, the tank concentrate inlet 102 being connected to the concentrate outlet 203 of the water purification assembly 200 through a second concentrate line 400 when the raw water tank 100 is in an installed state. In some application scenarios, the water purifier may not be convenient to drain the concentrate to the outside of the water purifier through the drain port 70, e.g., the water purifier may be placed in a bedroom or office. At this time, the concentrate may be discharged to the raw water tank 100 through the second concentrate line 400. In some embodiments, a partition may be provided in the raw water tank 100, and the partition may partially separate the tank concentrate inlet 102 and the tank water passing port 101, reducing the proportion of concentrate mixed with raw water or avoiding mixing of concentrate with raw water. To make the water purification machine compatible with different usage scenarios, the water purification machine may further comprise a valve assembly for controlling the second concentrate line 400 to be shut off at least along a predetermined direction from the tank concentrate inlet 102 to the concentrate outlet 203 of the water purification assembly 200 when the first concentrate line 300 is turned on. Specifically, when the first concentrate line 300 is conducted, the second concentrate line 400 may be divided into 1) one-way conduction in a direction opposite to a predetermined direction, and concentrate may enter the raw water tank 100 along the second concentrate line 400, and 2) the second concentrate line 400 may be shut off in both directions. It is easily understood that if the valve assembly is not provided, raw water in the raw water tank 100 may enter the first concentrate line 300 through the second concentrate line 400 and flow out of the drain port 70 in the case that the first concentrate line 300 is conducted. The valve assembly may be provided to allow only the concentrated water to flow out of the drain port 70, avoiding the raw water from leaking out of the drain port 70.

As described above, the water purifying machine may use only the raw water tank 100 as a water source in the case where tap water at a tap water port is interrupted or not connected. At this time, the water level in the original water tank 100 gradually decreases. In the case where the concentrate enters the raw water tank 100 through the tank concentrate inlet 102, the user also needs to empty the concentrate in the raw water tank 100 and then replenish a sufficient amount of raw water. At this time, the prompting device can prompt the user to replace the water in the original water tank 100 in time, or prompt the user that the water source is interrupted and the water purification cannot be continuously provided. It should be noted that, in the case where the concentrated water outlet 203 of the water purification assembly 200 is only connected to the first concentrated water pipeline 300, the lower water level limit 103 may be set lower, or may even be the water level at which the original water tank 100 is emptied, because the concentrated water generated during the water production process of the water purification assembly 200 does not need to flow back to the original water tank 100. In the case where the concentrate outlet 203 of the water purification assembly 200 communicates with the first concentrate line 300 and the second concentrate line 400, since concentrate generated during the water production process of the water purification assembly 200 may flow back to the raw water tank 100, the lower water level limit 103 may be set higher, for example, a water level at which concentrate can be generated when all raw water in the full raw water tank 100 is consumed.

When tap water is connected to the tap water port 80, the original water tank water level is replenished when it is lowered, and therefore the water level lower limit 103 is not reached. If the concentrate is returned to the original tank, the user may not always empty the original tank of concentrate. In this case, there may occur a case where concentrated water accumulates in the raw water tank, resulting in an increasingly higher raw water concentration. In this regard, the water purifier may alert a user to empty the original water tank 100 through a water quality detection assembly, or a timing function, as described below. In the case of discharging the concentrated water through the drain port 70, it is unnecessary to empty the original water tank 100.

For example, the first rich water line 300 may be cut off. In general, when the first rich water pipe 300 is turned on, the rich water hardly generates pressure in the second rich water pipe 400. Thus, the concentrated water almost entirely flows out of the drain port 70 and does not enter the raw water tank 100. When the first concentrate line 300 is shut off, the drain port 70 does not flow concentrate, and the pressure of concentrate may at least overcome the pressure of the raw water in the raw water tank 100 to enter the raw water tank 100. In the case where the purified water dispenser is provided with a valve assembly, the concentrated water may overcome the resistance of the valve assembly and the pressure of raw water in raw water tank 100, and thus enter raw water tank 100. In summary, by blocking the first concentrate line 300, the purified water dispenser can be switched from concentrate through the drain port 70 to concentrate back to the original water tank 100, which can be applied to various application scenarios, and the model and kind of the purified water dispenser can be standardized and changed by itself according to the use environment of the user. As described above, the raw water tank 100 is detachable, and in case of shortage of raw water in the raw water tank 100, a user can detach the raw water tank 100 to conveniently empty the concentrated water together with the residual raw water and to replenish new raw water.

As described above, the concentrated water generated in the water preparing process of the water purifying assembly 200 may be returned to the raw water tank 100 by blocking the first concentrated water line 300. Illustratively, the water purifier may further include a closure (not shown) for opening or closing the drain opening, and the first concentrate line 300 is shut off when the closure closes the drain opening. The closure may include a plug or cap that may be threadably or frictionally retained to the drain opening 70 to prevent the flow of concentrate from the drain opening 70. In this case, the valve assembly may be configured to automatically open under water pressure, so that switching of the way in which the purified water dispenser discharges concentrate is accomplished at a lower cost without control. In an embodiment not shown, the closure may also include a mechanical valve or faucet structure disposed at the drain opening.

Illustratively, the water purification machine may further include a first concentrate valve 310 disposed on the first concentrate line 300, the first concentrate line 300 being closed when the first concentrate valve 310 is closed. By providing the first concentrated water valve 310, the water purifying dispenser can prevent the concentrated water from flowing out of the drain port 70 through the first concentrated water valve 310 and return the concentrated water to the raw water tank 100 in response to the user's operation. Thus, the user does not need to plug the water outlet 70 through the plug or the cover body, the problem of loss of the plugging piece is avoided, and the problem of attractive appearance influence caused by tying the plugging piece on the water purifying and drinking machine through the rope is avoided. In the case where the water purification machine is provided with the first concentrated water valve 310, the valve assembly may be configured to be opened by itself under water pressure, or may be controlled to be opened and closed in reverse of the opening and closing of the first concentrated water valve 310.

The valve assembly may include one or more of the following. In the exemplary embodiment shown in fig. 3, the valve assembly may include a first one-way valve 410. The first check valve 410 may be provided on the second concentrate line 400, the first check valve 410 being configured to be unidirectionally conductive in a direction opposite to the aforementioned predetermined direction. That is, the first check valve 410 may be unidirectional in a direction from the concentrate outlet 203 of the water purification assembly 200 to the tank concentrate inlet 102. The first check valve 410 may be automatically opened under water pressure without control, and can prevent raw water in the raw water tank 100 from leaking from the water outlet 70 in case that the first concentrate line 300 is conducted. In the case that the valve assembly includes only the first check valve 410, the first concentrate line 300 may be blocked by the blocking member, or the blocking may be achieved by the first concentrate valve 310.

Taking the diaphragm type check valve as an example of the first check valve 410, the concentrated water in the second concentrated water pipeline almost only needs to overcome the pressure of the water in the original water tank 100 in the conducting direction of the first check valve 410, and can pass through with small pressure. The first water concentrate line 300 may deposit scale during long-term use, resulting in a further increase in pressure within the portions of the first and second water concentrate lines 300, 400 that are in direct communication with the first water concentrate line 300. Thus, a portion of the concentrate may be discharged from the drain port 70 through the first concentrate line 300 while another portion returns to the original tank 100 under pressure. Illustratively, the first check valve 410 may be configured to have a relatively high opening pressure, and the pressure of the concentrate water may cause the first check valve 410 to open only when the drain port 70 is mostly or even completely closed. In this way, in the case that the first concentrate line 300 is normally conducted, the first check valve 410 is equivalent to completely closing the second concentrate line 400 from both directions, so that the concentrate is prevented from entering the raw water tank 100, and is discharged only through the water outlet 70, without the need for the user to pour the concentrate in the raw water tank 100.

In the exemplary embodiment shown in FIG. 4, the valve assembly may include a second concentrate water valve 420. The second concentrated water valve 420 may be provided on the second concentrated water pipe 400, and the second concentrated water valve 420 may be closed with the first concentrated water pipe 300 being turned on, thereby preventing raw water of the raw water tank 100 from leaking from the second concentrated water pipe 400. The second concentrate valve 420 may also be opened with the first concentrate line 300 shut off so that concentrate may enter the raw water tank 100 through the second concentrate line 400. In this case, the first concentrated water line 300 is preferably shut off by the first concentrated water valve 310, and the first concentrated water valve 310 and the second concentrated water valve 420 are not simultaneously opened or closed. Of course, the present application does not exclude an embodiment of controlling the opening and closing of the second concentrated water valve 420 by detecting the water pressure in the pipe or according to the blocking condition of the water outlet 70.

In yet another exemplary embodiment, the valve assembly may include a switching valve (not shown). The switching valve may include a valve water inlet, which may be communicated to the concentrate outlet 203 of the water purification assembly 200, a first valve water outlet, which may be communicated to the water inlet of the first concentrate line 300, and a second valve water outlet, which may be communicated to the water inlet of the second concentrate line 400. By controlling the switching valve, it is possible to control the discharge of the concentrate to the drain port 70 or the return of the concentrate into the raw water tank 100, at which time there is no need to provide a blocking member or the first concentrate water valve 310. Of course, the present application does not exclude embodiments in which one or more of the types of valve assemblies described above are coupled to each other.

Illustratively, the water purifier may further include a water quality detection assembly for detecting the water quality in the raw water tank 100. In particular, the water quality detection assembly may detect using a total dissolved solids (TDS, total dissolved solids) detector. In the case that the concentrated water is returned to the raw water tank 100, if the TDS value of raw water in the raw water tank 100 is excessively high, the service life of the filter cartridge 210 may be affected, even resulting in degradation of the quality of the supplied purified water. The water quality detection assembly is arranged, and the controller can timely judge whether the water quality is too bad. And when the water quality does not reach the standard, the control prompt device sends out prompt information to remind a user to empty the original water tank 100 in time. In this case, the user may need to change water before the raw water level in the raw water tank 100 is lower than the lower water level limit 103. To improve the accuracy of the detection, a detection part of the water quality detection assembly, such as a TDS probe, may be provided at the tank water passing port 101 or on a pipe connected between the tank water passing port 101 and the raw water inlet 201 so as not to be disturbed by the concentrated water just discharged into the raw water tank 100. Thus, the service life of the filter element 210 can be prolonged under the condition that the water source with poor water quality is used in the water purifying and drinking machine.
