Description

Ice machine

The present invention relates to an auger ice maker that ices a predetermined size of ice.

Generally, an ice making device in which a refrigerating cycle (manufacturing ice) or a cooling cycle (cold water discharge) is applied to an ice making device or some water purifiers, cools or freezes water in a cylinder through an evaporator simultaneously with circulation of a refrigerant through a compressor. It consists of a refrigerating cycle used to obtain ice or cold water and an ice making unit surrounded by the evaporator of the refrigerating cycle to produce a predetermined ice and cold water. When the water reaches a certain level in the cylinder of the ice making unit, The water supply was automatically shut off and the level of the cylinder and water tank had to be maintained at the same level. The reason for having such a water supply tank is that automatic deicing (cooling) is performed when the maximum height of the space of the cylinder is reached, and a freezing and cooling cycle is started to produce ice.

That is, FIG. 1 of the accompanying drawings is a figure which shows the example of the conventional auger ice-making apparatus.

As shown in this figure, the conventional ice making and cooling facilities have a water supply solenoid valve and a water level control circuit on the water supply side centered on the water supply tank, and a pull lot and a water level sensor in the water supply tank so as to be linked thereto. The water supply solenoid valve is operated when the water level changes, and the overflowed water consists of a system discharged through the overflow pipe.

Water supply solenoid valve (1), water supply pipe (10), water supply tank (2), water supply pipe (6) for supplying ice-making water to the cylinder 220, drain pipe (7) for draining the water in the cylinder 220, water supply tank ( 2) and an overflow drain pipe 5 for discharging excess water from the upper and lower drain pans (not shown).

The water level detection switch 3a which detects the liquid level of ice-making water is accommodated in the water supply tank 2, and when the float 3 is lower than the water level, the water level detection switch 3a is turned ON and a water supply solenoid valve (1) is opened to replenish the ice-making water in the water supply tank (2). When the float 3 rises and reaches the purified water level, the water level detecting switch 3 is turned off, and the water level solenoid valve 1 is closed to operate in connection with this, so that the water supply to the water supply tank 2 is stopped.

In this way, the auger deicing device as a continuous ice making machine is provided between the time until the water level detection switch 3a is turned ON, that is, until the water supply solenoid valve 1 starts the next opening operation. By this, all the ice-making water in the water supply tank 2 has produced ice.

Therefore, the reason for maintaining the water level in the conventional ice-making cylinder which forms the principle of this ice-making principle is that if ice-making is performed in some empty spaces when the refrigeration and cooling cycles are started when the water is not sufficiently filled, it is caused by the subcooling of the partially frozen ice. A device that leads to mechanical failure due to constrained screw rotation in the cylinder, leading to mechanical accidents, while destroying the refrigerating system by the "liquid back" phenomenon where refrigerant is not consumed by cold energy as a sufficient amount of ice into the compressor. There was a problem that must be avoided to cause a fatal accident.

In the meantime, the design of the water supply tank has been made so that the water level of the water supply tank and the ice making cylinder are located on the same line.

In addition, due to the equipment limitations of the water supply system, the deicing and cooling capacity depends on the design of the water supply tank, thus making it difficult to manufacture a compact ice maker.

Therefore, in order to simplify and reduce the structure of such an ice making device (water purifier), it has been required to improve the water level control device on the water supply side without a feedwater solenoid valve, a water supply tank, an overflow pipe, and a water level control circuit system.

Comprising a passage 350, the refrigerant circulates along the refrigerant passage.

The shock motor 340 is formed of, for example, a DC motor, and is configured such that the rotation speed is controlled (accelerated, decelerated, held, stopped, etc.) by the output value of the ice making load control circuit A.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, overall embodiments of the present invention will be described in detail with reference to the accompanying drawings.

7A through 7L show drawings of various embodiments of the present invention, and FIGS. 8A through 8H illustrate a flow chart according to various embodiments of the present invention.

The ice making apparatus of the present invention according to these drawings is a water supply pipe 6 for supplying ice-making water to the water supply solenoid valve 1, the water supply pipe 10, the water supply tank 2, and the cylinder 220 as shown in the related art. Tactical instead of the water level control device consisting of a drain pipe 7 for draining the water in the cylinder 220, an overflow drain pipe 5 for discharging excess water from the water supply tank 2 or upper and lower drain pans (not shown). One level control device 100 is applied.

The refrigeration cycle unit 300 of the ice making apparatus of the present invention, the compressor 360, the condenser 330, the fan motor 340 for driving the cooling fan 341 of the condenser 330, expansion valve 320, evaporator 310 and the refrigerant passage, the refrigerant flows along the refrigerant passage.

The shock motor 340 is configured such that the rotation speed thereof is appropriately controlled (acceleration, deceleration, holding, stopping, etc.) by the ice making load control circuit A. FIG.

The ice making unit 200 includes a cylinder 220 disposed in the up and down directions, an evaporator 310 wound and mounted on the outer circumferential surface of the cylinder 220, and a drive motor 250 in the cylinder 220. It consists of a screw 240 having a spiral blade 241 that rotates by the rotation, and a refrigeration casing 210 covering the entire cylinder 220 to block the evaporator 20 from the outside air. Ice frozen on the inner circumferential surface of the cylinder 220 is scraped upward by the spiral blade 241 and cut by a cutter.

Due to the change in the ice-making capacity such as ice quality and solid state caused by the change of the conditions (ambient temperature, water supply temperature, voltage / current, etc.) of the ice maker during operation This results in a change in the water supply, which is solved by automatic adjustment even if there is a change in operation as the water level change in the cylinder is always kept constant by the above-described improved " water level controller ".

According to the present invention, when the water inlet is connected to the water supply, the water supply is always maintained regardless of whether or not the ice making device is operated.

At this time, the ice making load control circuit A detects the temperature by the condenser 330 temperature sensor 332 of the first embodiment, which will be described later, and adjusts and drives the motor 340 according to the temperature. If it is higher than the reference value, the fan 341 is increased to control the ice making ability. Of course, by adjusting the rotational speed of the compressor 360 it can be obtained the same result.

This operation is repeatedly executed during the operation of the ice making apparatus and stopped by turning off the power supply. This makes it possible to accurately determine the fluctuation of the ice making capacity, and for example, by deliberately lowering the condensing capacity of the condenser 330 in the winter when not much ice is required, excessive ice making (e.g., the formation of ice is excessive and unnecessarily around the ice making part). The phenomenon causing the ice state, hereinafter referred to as ice making, can be smoothly avoided, and further, an overload can be prevented from being applied to the ice making unit 200.

First, an operation process of FIGS. 8A to 8H will be described.

Figure 8a is to measure the temperature of the condenser after the operation of the ice maker to compare it with the reference temperature and to reflect on the motor to control the condensation temperature, Figure 8b is to measure the condenser temperature after the ice making operation and the reference temperature and After the comparison, the difference is linked to the compressor to increase and decrease the compression force of the compressor to control the ice making efficiency. FIG. 8C measures the temperature of the evaporator after the start of ice making and measures the temperature and compares it with the reference temperature. 8D shows that the condensation temperature is controlled by reflecting it to the back motor. In FIG. 8D, if the temperature of the evaporator is measured after the start of ice making, and the temperature is lower than the standard value, the compressor is increased in the compression operation of the compressor and the compressor is increased. If it is high, the compressor is decelerated and controlled. FIG. 8E shows the reference value by measuring the evaporator temperature of the compressor after the start of ice making. If it is not reached, the compressor is increased to reflect the compressor's operation, and if it is higher than the reference value, the compressor is operated to control the motor. FIG. 8F measures the water supply after the start of ice making. The compressor is increased to reflect the operation, and if it is higher than the reference value, the motor is controlled and operated. FIG. 8g measures the water supply amount after the start of ice making, compares it with the reference value, and if it does not reach the reference value, reflects it again in the water supply amount. If it is high, it controls the condensation efficiency by operating the motor. Figure 8g measures the water supply after the start of ice making and if it does not reach the standard value, it is reflected in the compressor operation of the compressor and the compressor is increased again. To control it.

The operation of each embodiment will be described below.

Example 1

In the first embodiment, as shown in FIGS. 7A and 8A, a temperature sensor 332 is installed to detect the temperature of the condenser 330, and the measured temperature and the predetermined temperature of the condenser 330 measured by the temperature sensor 332 are determined. The magnitude of any reference temperature is compared. When the measured temperature measured by the temperature sensor 332 is lower than the reference temperature, the rotation speed of the shock motor 340 is controlled or stopped by the ice making load control circuit A. FIG. This intentionally lowers the condensation capacity and suppresses excessive ice making.

Therefore, when the ice making operation is started, the temperature sensor 332 starts measuring the temperature of the condenser 330, and the magnitude of the measured temperature and the reference temperature is compared. When it is determined that the measured temperature is lower than the reference temperature, the ice making load control circuit A determines that the ice making apparatus is in an excessive ice making state and controls the rotation speed of the cooling fan motor 340 of the condenser 330. And the rotation of the shock motor 340 is stopped or decelerated. In addition, when the temperature of the central temperature of the condenser 330 is measured by the temperature sensor 332, the situation of the refrigeration cycle part is minimized by minimizing the measurement point. You can judge.

According to the accompanying drawings, as shown in FIG. 7F, the ice making state of the present invention can be controlled in consideration of the outside air temperature by providing a temperature sensor 16 for measuring the outside air temperature in the ice making device of the present embodiment. That is, in the ice-making load control circuit A, a plurality of reference temperatures different from each other with respect to the condenser 330 are set in advance. Since the ice making state is influenced by the outside air temperature, the condenser 330 used for the rotation speed control of the cooling fan motor 340 based on the temperature of the condenser 330 and the rotation speed control based on the outside air temperature are performed. By selecting the reference temperature of), the ice making ability can be appropriately controlled according to the surrounding environment.

Example 2

As shown in FIG. 7B, in the ice making apparatus of Example 1, a pressure sensor (not shown) for detecting the high pressure side pressure and the low pressure side pressure of the compressor 360 is provided, and the pressure at the inlet is provided by these pressure sensors. The pressure difference between the outlet and the outlet is detected. If the pressure difference is large, the motor is started (or increased), and if it is low, the motor is stopped (or decelerated). Since other configurations are the same as those in the first embodiment, only different configurations will be described.

The compression ratio is calculated from the high pressure side pressure and the low pressure side pressure measured by the pressure sensor 362 respectively provided at the inlet and outlet of the compressor 360, and the magnitude of this compression ratio and any reference value are compared.

When the compression ratio is smaller than the reference value, the ice load control circuit A controls the rotation speed of the shock motor 340 to be slow. This intentionally lowers the condensation capacity and suppresses excessive ice making.

In addition to controlling the compression ratio, the ice making apparatus is operated according to the outside air temperature, thereby increasing the ice making efficiency.

Figure 7j of the accompanying drawings is another embodiment of the ice making device of the present invention by comparing the inlet and outlet pressure of the compressor to increase, decrease, stop the motor 340, the ice making device reflecting the outside air temperature here Operate more efficiently.

Preferably, it is an ice making apparatus which detects the water supply temperature supplied to the water supply pipe as the temperature sensor 14 and reflects it, as shown in FIG. 7F.

8b, 8c, 8d, 8f, and 8h of the accompanying drawings measure the condenser temperature 332 and reflect it to increase and decrease the compression force of the compressor (8b, 8c), and measure the evaporator temperature to reflect the increase and decrease of the compressor. (8f), by measuring the water supply amount and reflecting it in the compressor, an efficient ice making operation can be obtained.

Example 3

Embodiment 3 is an evaporator temperature reference value set in the ice making load control circuit A through the temperature sensor 312 installed between the evaporator 310 and the expansion valve 320 in the ice making apparatus of the present invention as shown in FIG. Compared with the low motor, the shock motor 340 is stopped or decelerated, and when the high motor is operated, the motor 340 is operated to increase or decelerate efficiently.

The temperature sensor 312 is installed at the inlet of the evaporator 310 to measure the evaporation temperature of the refrigerant in the evaporator 310, and the temperature sensor 312 can detect the ice making capacity at the evaporation temperature.

According to this embodiment, when the ice making operation is started, the temperature sensor 312 starts the measurement of the evaporation temperature of the refrigerant, and the evaporation temperature is compared with a preset reference temperature. As a result of the comparison, when it is determined that the evaporation temperature is lower than the reference temperature, the ice making load control circuit A determines that the ice making device of the present invention is in the state of excessive ice making, and the cooling motor 340 for cooling the condenser 330 Decrease or stop the rotation of) to lower the ice making capacity. In addition, if it is determined that the evaporation temperature is higher than the reference temperature, the ice making load control circuit A determines that the ice making device of the present invention does not reach the desired ice making capability, and the rotation of the cooling fan motor 340 of the condenser 330 is performed. Increase the number to improve the ice making ability. If it is determined that the evaporation temperature is equal to the reference temperature, the ice making load control circuit A maintains the rotation speed of the cooling fan motor 340 as it is.

On the other hand, the present invention is the ice making apparatus of the embodiment of the present invention shown in Figure 7g of the accompanying drawings detects the temperature of the water supplied to the water, and after detecting the evaporator temperature and compares this temperature with each reference value to determine the ice making load control circuit (A) Through the condenser fan motor 340 to determine whether to increase or decrease and stop. Therefore, the ice making operation taking into account the water supply temperature and the evaporator temperature at the same time is made is more efficient than the conventional ice making device.
