The air filter may include a deodorizing filter or a photocatalyst.

Referring to FIGS. 12 and 13 , the food supply device may include a pressure module 76 . The pressure module 76 is for adjusting the pressure inside the inner case 30 . In this embodiment, the pressure module 76 may suck air from the second feed storage compartment C2b and discharge it to the beverage storage compartment C1. The pressure module 76 lowers the pressure in the second feed storage compartment C2b and makes the second feed storage compartment C2b a kind of negative pressure chamber. Accordingly, oxidation of the feed stored in the second feed storage compartment C2b can be prevented.

In this embodiment, the pressure module 76 may be disposed on the third insulating wall W3 partitioning the second feed storage chamber C2b from the take-out chamber C3 in which the tray unit 170 is disposed.

Specifically, the pressure module 76 may include a vacuum pump, and the vacuum pump may be a diaphragm pump. The vacuum pump may exhaust air in the second feed storage compartment C2b while operating by receiving power. The vacuum pump vibrates the thin plate to contract/expand the volume of the closed space to suck in or discharge air, and in the process, the air in the second feed storage compartment C2b can be discharged to the outside.

An air inlet 77 of the vacuum pump may be connected to the second feed storage compartment C2b, and an air outlet 78 of the vacuum pump may be connected to the beverage storage compartment C1. As shown in FIG. 13, the inlet 77a of the air inlet 77 is opened toward the inside of the second feed storage compartment C2b, and the outlet 78a of the air outlet 78 of the vacuum pump is the beverage storage compartment. It opens toward the inside of (C1). In this way, when the outlet 78a of the air outlet 78 of the vacuum pump is opened toward the inside of the beverage storage compartment C1, the air inside the second feed storage compartment C2b is not discharged to the outside and is returned to the inner case. Since it flows into the inside of (30), loss of cold air can be reduced.

When the vacuum pump of the pressure module 76 is operated, negative pressure can be formed in the second feed storage compartment C2b by the vacuum pump, and oxidation of the feed can be prevented. Meanwhile, since the beverage tank 83 of the beverage storage compartment C1 is shielded by the tank cover 84 to be described below, freshness can be maintained even if oxidation is not prevented through negative pressure.

The vacuum pump may start operating when the pressure inside the second feed storage compartment C2b is higher than a reference value, and stop operating when the pressure is lower than the reference value (for example, 1 atmospheric pressure). Although not shown, the pressure inside the second feed storage compartment C2b may be measured by a separate pressure switch. The pressure switch may be included in the pressure module 76.

The pressure module 76 can adjust not only the second feed storage compartment C2b, but also the pressure inside the first feed storage compartment C2a. The second damper (D2) connecting the first feed storage compartment (C2a) and the second feed storage compartment (C2b) is opened, and at the same time, the gap between the first feed storage compartment (C2a) and the beverage storage compartment (C1) is opened. When the connecting first damper D1 is blocked, the first feed storage compartment C2a and the second feed storage compartment C2b are connected to each other so that pressures can be synchronized. In this state, when the vacuum pump operates, the second feed storage compartment C2b is exhausted and the first feed storage compartment C2a is also exhausted at the same time, so that the pressure inside each can be lowered. In addition, when the internal pressures of the first feed storage chamber (C2a) and the second feed storage chamber (C2b) both satisfy conditions by the pressure switch, the operation of the vacuum pump may be stopped. The operation of the pressure module 76 may be automatically controlled by a separate control unit (not shown).

At this time, a pressure sensor (not shown) may be provided in the stopper 195 to detect that the tray unit 170 has moved to the end.

Next, a process of circulating the air inside the food supply device will be described. Referring to FIG. 11 , the air cooled by the cooling unit 60 is discharged forward, that is, in the beverage storage compartment C1 direction (arrow B). And the heat generated from the thermoelectric element 65 is discharged to the outside (arrow A) of the outer case 10, which is the rear. The cold air discharged into the beverage storage compartment C1 cools the beverage storage compartment C1, and accordingly, the temperature of the beverage stored in the beverage tank 83 may be lowered. For example, if the temperature of the beverage preferred by the companion animal is 15 degrees, the set temperature of the beverage storage compartment C1 may be cooled to 15 degrees.

At this time, the recovery unit 69b may discharge the air inside the beverage storage compartment C1 again in the direction of the cooling unit 60 (direction of arrow B'). If the beverage storage compartment (C1) and the first feed storage compartment (C2a) are blocked from each other by the first damper (D1), the air inside the beverage storage compartment (C1) is discharged through the discharge unit (69a). and may be circulated through the recovery part 69b.

Although not shown, when the temperature of the beverage storage compartment (C1) detected by the temperature sensor disposed in the beverage storage compartment (C1) reaches a set temperature, the first damper (D1) is opened and the beverage storage compartment (C1) The cold air of may be delivered to the first feed storage compartment C2a. Referring to FIG. 14, a path through which the air in the beverage storage compartment C1 is supplied to the first feed storage compartment C2a through the first damper D1 is indicated by an arrow ①.

The cold air supplied to the first feed storage compartment C2a lowers the temperature of the first feed storage compartment C2a. At this time, a temperature sensor (not shown) is also provided in the first feed storage compartment C2a to measure the temperature of the first feed storage compartment C2a. If the temperature of the first feed storage compartment (C2a) reaches the set temperature, the second damper (D2) is opened, and the cold air in the first feed storage compartment (C2a) can be transferred to the second feed storage compartment (C2b). there is. In FIG. 14, an arrow ② indicates a direction in which cold air in the first feed storage compartment C2a is transferred to the second feed storage compartment C2b. Since the second feed storage compartment C2b is disposed below the first feed storage compartment C2a, cold air can naturally move to the second feed storage compartment C2b.

Meanwhile, the air in the first feed storage chamber (C2a) may be discharged through the recovery duct (70). Since the first duct suction part 73 of the recovery duct 70 is connected to the rear of the first feed storage chamber C2a, the air in the first feed storage chamber C2a is supplied to the first duct suction part 73. ) is discharged in the direction of (arrow ① 'direction in FIG. 14). Also, the air recovered through the recovery duct 70 may be supplied to the cooling unit 60 again.

In addition, air in the second feed storage compartment C2b may also be discharged through the recovery duct 70 . Since the second duct suction part 75 of the recovery duct 70 is connected to the rear of the second feed storage chamber C2b, the air in the second feed storage chamber C2b is supplied to the second duct suction part 75 ) is discharged in the direction of (arrow ② 'direction in FIG. 14). Also, the air recovered through the recovery duct 70 may be supplied to the cooling unit 60 again.

In this way, the air in the first feed storage compartment (C2a) and the air in the second feed storage compartment (C2b) are not discharged to the outside of the outer case 10, but are recovered through the recovery duct 70 and are returned to the cooling unit. It is fed back to (60). Therefore, it is possible to prevent cold air from the first feed storage compartment (C2a) and the second feed storage compartment (C2b) from escaping to the outside, and odors generated from feed and snacks may not escape to the outside.

When each temperature of the beverage storage compartment (C1), the first feed storage compartment (C2a), and the second feed storage compartment (C2b) satisfies the set temperature, the first damper (D1) and the second damper (D2) It is blocked so that the respective rooms may remain independent of each other. In addition, when dry feed is stored in the second feed storage compartment (C2b), since the temperature of the second feed storage compartment (C2b) may be maintained at room temperature, cold air needs to be transmitted through the second damper (D2). there will be no

Meanwhile, the first feed storage chamber (C2a) and the second feed storage chamber (C2b) may maintain negative pressure. Referring to FIG. 13 , a pressure module 76 is installed in the inner case 30 , and the pressure module 76 can adjust the pressure inside the inner case 30 . In this embodiment, the pressure module 76 may suck air from the second feed storage compartment C2b and discharge it to the beverage storage compartment C1. In this case, the pressure module 76 lowers the pressure of the second feed storage chamber C2b and makes the second feed storage chamber C2b a kind of negative pressure chamber. Accordingly, oxidation of the feed stored in the second feed storage compartment C2b can be prevented.

An air inlet (77) of the vacuum pump is connected to the second feed storage compartment (C2b), and an air outlet (78) of the vacuum pump is connected to the beverage storage compartment (C1). A negative pressure may be formed in the second feed storage compartment C2b by a vacuum pump, and oxidation of feed may be prevented. Meanwhile, since the beverage tank 83 of the beverage storage compartment C1 is shielded by the tank cover 84 to be described below, freshness can be maintained even if oxidation is not prevented through negative pressure.

The vacuum pump may start operating when the pressure inside the second feed storage compartment C2b is higher than a reference value, and stop operating when the pressure is lower than the reference value (for example, 1 atmospheric pressure). In addition, the pressure module 76 can adjust not only the pressure in the second feed storage compartment C2b but also the pressure inside the first feed storage compartment C2a. The second damper (D2) connecting the first feed storage compartment (C2a) and the second feed storage compartment (C2b) is opened, and at the same time, the gap between the first feed storage compartment (C2a) and the beverage storage compartment (C1) is opened. When the connecting first damper D1 is blocked, the first feed storage compartment C2a and the second feed storage compartment C2b are connected to each other so that pressures can be synchronized. In this state, when the vacuum pump operates, the second feed storage compartment C2b is exhausted and the first feed storage compartment C2a is also exhausted at the same time, so that the pressure inside each can be lowered.

Next, looking at the process of dispensing the beverage, the beverage may be supplied through the beverage unit 80 and the flow path module 100 . For reference, it is exemplified that the beverage is water. In this embodiment, (i) external water such as tap water or purified water is directly taken out to the tray unit 170, or (ii) external water such as tap water or purified water is injected into the beverage tank 83 and cooled After that, it can be taken out to the tray unit 170.

First, looking at the process in which water is directly taken out to the tray unit 170, when external water is supplied to the water filter 101 through the external connection pipe P1, water purified through the water filter 101 is delivered to the first valve V1 through the main supply pipe P2a. The first valve (V1) blocks the beverage injection pipe (P3a) and opens the direct water supply pipe (P2b) to move purified water to the direct water discharge nozzle (P2c) connected to the direct water supply pipe (P2b). In addition, the bowl 177 of the tray unit 170 may be filled with water purified through the direct water discharge nozzle P2c.

Looking at the process of supplying cooling water, when external water is supplied to the water filter 101 through the external connection pipe P1, water purified through the water filter 101 is supplied to the main supply pipe P2a. ) through the first valve (V1). The first valve (V1) blocks the direct water supply pipe (P2b) and opens the beverage injection pipe (P3a) so that purified water is injected into the beverage tank (83).

After the water contained in the beverage tank 83 is cooled, it may be discharged by the flow pump 103 . The flow pump 103 delivers the beverage stored in the beverage tank 83 to the second valve V2 through the beverage discharge pipe P3b and the beverage delivery pipe P3c. The second valve V2 opens the beverage delivery pipe P3c and the tray discharge nozzle P3d, respectively, so that the bowl 177 is filled with cooled water through the tray discharge nozzle P3d.

Meanwhile, the beverage tank 83 and the flow path may be washed using the flow path pump 103, the first valve V1 and the second valve V2. The direct water supply pipe (P2b), the main supply pipe (P2a), and the beverage injection pipe (P3a) are blocked by the first valve (V1), respectively, and the tray discharge nozzle (P3d) by the second valve (V2). ) is blocked. In this state, when the beverage tank 83 operates, the water stored in the beverage tank 83 is discharged from the beverage discharge pipe P3b and moved through the beverage delivery pipe P3c. Also, the water may be discharged outward through the external discharge pipe P4 connected to the second valve V2. Through this, it is possible to remove the residual water of the beverage tank 83 and the residual water remaining in the flow path. In addition, the beverage tank 83 may be washed by repeating the process of refilling the beverage tank 83 with water through the flow path module 100 and discharging the filled water through the previous process.

Next, looking at the process of taking out the feed, the feed (wet food snack, etc.) stored in the first feed storage compartment (C2a) and the feed (dry feed) stored in the second feed storage compartment (C2b) are taken out independently of each other. It can be. First, looking at the process of taking out the feed from the first feed storage compartment C2a, when the first take-out motor M1 rotates, the first feeder 140 of the first feed supply module 130 rotates to remove the feed. transport forward.

At this time, the first rear pusher 143 of the first feeder 140 is in charge of stirring and fast feeding functions of the feed, and delivers the feed to the first front pusher 145. The conveyed feed is injected between the blades of the first front pusher 145, and the feed is divided by a certain amount within a limited pitch between the blades. These precisely classified feeds are delivered to the first discharge regulator 147 . Finally, the first ejection regulator 147 ejects the feed through the first quantitative ejection port 134a of the first ejection guide 134 .

The feed taken out from the first feed supply module 130 moves downward along the feed duct 123 and is contained in the bowl 177 of the tray unit 170 . Also, dry feed may be supplied by the second feed supply module 150 in the same manner.

In this embodiment, since the bowls 177 are composed of a plurality, rotation of the tray unit 170 is required to put different food or drinks in each bowl 177 . Looking at the process of rotating the tray unit 170, when the tray rotation motor 181 of the rotation module 180 rotates, the first drive gear 183a meshed with the tray rotation motor 181; The second driving gear 183b is engaged and rotates. Also, the second drive gear 183b engages with the main rotation gear 185 provided at the bottom of the rotation tray 175 to rotate the main rotation gear 185 .

When the main rotation gear 185 rotates, the rotation tray 175 also rotates, and the positions of the bowls 177 change. For example, when the rotation tray 175 rotates 270 degrees in the state shown in FIG. 36, the state shown in FIG. 37 is obtained. At this time, the rotation angle of the rotation tray 175 may be detected by the rotation sensor 188 and controlled. Through the rotation of the rotating tray 175, feed and beverage may be contained in each of the bowls 177, respectively.

After food and beverages are contained in the bowls 177, the tray unit 170 can be withdrawn to provide food and beverages to companion animals. Looking at this tray withdrawal process, the pull-out motor 191 constituting the tray withdrawal module 190 rotates the screw shaft 193 while rotating. When the screw shaft 193 is rotated, the take-out bracket 179 linearly moves along the screw shaft 193.

The withdrawal bracket 179 is connected to the tray door 171 of the tray unit 170 through the guide bridge 179b. Therefore, in the process of moving the withdrawal bracket 179, the tray unit 170 also moves together. When the tray unit 170 moves forward, the bowls 177 of the rotating tray 175 may also be drawn forward together. 43 to 45, the tray door 171, the tray guide 173, the rotating tray 175, and the bowl 177 constituting the tray unit 170 gradually move forward (in the direction of the arrow). can see At this time, when the withdrawal bracket 179 moves to the front of the supply station 17, it comes into contact with the stopper 195 and stops its operation.

Referring to FIG. 46, the respective bowls 177 are shown separated from each other. The rotation tray 175 is provided with a separation rail R, and the bowl guides 176 may move in directions away from each other along the separation rail R. In this embodiment, the separation rail (R) forms three prongs, and bearings may be installed in each separation rail (R).

Although not shown, the separation rail R may include a rail fixing part fixed to the rotating tray 175 and a take-out rail coupled to the rail fixing part. The take-out rail may increase or decrease the total length of the separation rail R while linearly moving along the rail fixing part. At this time, the bowl guide 176 is coupled to the take-out rail and can move along the rail fixing part together with the take-out rail.

When the user moves the bowl guides 176 along the separation rail R, the respective bowls 177 move away from each other, resulting in a state as shown in FIG. 46 . As such, when the bowls 177 are separated from each other, several companion animals can eat food or drinks contained in each bowl 177 without interfering with each other. After the companion animals consume food, when the user puts the bowls 177 back to their original position and the tray take-out module 190 operates, the tray unit 170 is stored in the take-out room C3 again. can
