1 is a view showing a circuit diagram of a kimchi refrigerator for integral cold water purifier according to a preferred embodiment of the present invention.

Referring to FIG. 1, evaporators 32, 34, and 36 are respectively installed outside the first kimchi refrigerating chamber 26, the second kimchi refrigerating chamber 28, and the cold water tank 30. The refrigerant inlets of the evaporators 32 to 36 are connected to the outlet of the refrigerant pipe of the capillaries 20 to 24, and the refrigerant inlet of the refrigerant pipe of the capillaries 20 to 24 is connected to the solenoid valves 18a to 18c. have.

The refrigerant input side of the solenoid valves 18a to 18c is connected to an outlet side pipe of the dryer 16, and a condenser 12 and a hot pipe are connected between the refrigerant inlet side of the dryer 16 and the refrigerant outlet side pipe of the compressor 10. pipe 14 is connected.

In addition, the temperature control sensors 38 and 40 for detecting the temperature of the kimchi refrigerating chamber 26, 28 are installed at the time points of the evaporators 32, 34 installed in the kimchi refrigerating chamber 26 and 28, the evaporator 36 of the cold water tank 30 An end point is provided with a temperature control sensor 42 for controlling the refrigeration cycle of the cold water tank.

The temperatures of the first and second kimchi refrigerating chambers 26 and 28 and the temperature values of the cold water tank 30 detected by the temperature control sensors 38 to 42 are provided to a controller (not shown) that controls the cooling system. At this time, the control unit controls the compressor 10 and the solenoid valves 18a to 18c when the difference occurs by comparing the set temperature value of the cooling water with the set temperature value of the kimchi refrigerating chamber and the sensed temperature value, thereby controlling the cold water tank 30, The temperature of the 1st and 2nd kimchi refrigerating chambers 26 and 28 is controlled.

2 is a view showing the operation timing diagram of the cold water purifier and kimchi refrigerator shown in FIG.

Hereinafter, the control operation of the refrigeration cycle of the cold water purifier integrated kimchi refrigerator according to the present invention will be described in detail.

Now, when the solenoid valve 18a in the solenoid valve member 18 is opened and the compressor 10 is driven by the control of the control unit, the vapor refrigerant compressed from the compressor 10 to the high temperature and high pressure state is sent to the condenser 12 connected along the refrigerant pipe. The condenser 12 discharges the heat of condensation, condenses the high temperature and high pressure steam refrigerant through the refrigerant pipe, and supplies the medium temperature low pressure liquid refrigerant to the capillary tube 20 through the hot pipe 14, the dryer 16, and the open solenoid valve 18a.

The capillary tube 20 converts the liquid refrigerant of medium temperature and low pressure into a refrigerant having a low temperature and low pressure, and supplies it to the refrigerant inlet side of the evaporator 26 installed in the first kimchi refrigerating chamber 26. At this time, the evaporator 32 cools the temperature of the first kimchi refrigerator compartment 26 by taking the latent heat of evaporation of the liquid refrigerant of low temperature and low pressure.

The refrigerant vapor evaporated by the above operation is supplied to the compressor 10 connected on the refrigerant pipe, and the compressor 10 compresses the liquid refrigerant of low temperature and low pressure into a gas refrigerant of high temperature and high pressure and sends it to the condenser 12. By the operation of the refrigeration cycle as described above, the refrigerant charged in the compressor 10 and the refrigerant pipe is continuously circulated while also being in a liquid state or in a vapor (gas) state.

The refrigeration cycles of the second kimchi refrigerating chamber 28 and the cold water tank 30 shown in FIG. 1 are controlled by the control unit according to opening and closing of the solenoid valves 18b and 18c, and the operation of the refrigeration cycle is as described above.

The present invention detects the evaporation temperature of the evaporators 32 and 34 installed in the first and second kimchi refrigerating chambers 26 and 28 and the evaporator temperature of the evaporator 36 installed in the cold water tank 30 to control the opening and closing of the solenoid valves 18a, 18b and 18c. And freezing cycle of cold water purifier respectively.

The alternating control of the refrigeration cycle is based on the difference in temperature between the first and second kimchi refrigerating chambers 26 and 28 of the kimchi refrigerator and the cold water tank 30 of the cold water, that is, the evaporation temperature, as described above. It causes a lot of problems in the life of 10.

In order to solve the above problems, the present invention, as shown in Figure 1, the temperature control sensor 38, 40 of the Kimchi refrigerating chamber is installed at the time (refrigerant inlet) of the evaporator 26 and 28, the temperature control sensor 42 of the cold water purifier Was installed at the end of the evaporator 36 installed in the cold water tank 30 to control the cooling system of the cold water purifier before the refrigerant gas flowing into the compressor 10 in the liquid state when the refrigeration cycle of the cold water purifier is operated.

In other words, the temperature of the liquid gas generated at the end of the evaporator 36 installed in the cold water tank 30 to stop the operation of the refrigeration cycle. The application of the refrigeration cycle increases efficiency in controlling the amount of refrigerant packed in one compressor 10 having the same capacity because the refrigeration cycle of the Kimchi refrigerator and the refrigeration cycle of the cold water are different.

In addition, the operation of the three refrigeration system shown in Figure 1 is the two kimchi refrigerator in the two-room kimchi refrigerator having the first and second kimchi refrigerator compartment 26, 28 to distribute the load of the compressor 10 at the same time It is controlled so that it does not become a load. This control is performed by a control unit which controls the respective refrigeration cycles by inputting the outputs of the temperature control sensors 38, 40 and 42 and comparing them with the set temperatures.

For example, as shown in FIG. 2, the control unit alternately opens and closes two solenoid valves 18a and 18b corresponding to the first and second kimchi refrigerating chambers 26 and 28 according to a preset program as shown in FIG. 2. A load of 10 reduces about half. In addition, when the first kimchi refrigerating chamber 26 and the second kimchi refrigerating chamber 18 are controlled alternately, the time of simultaneous operation is overlapped so that the compressor 10 is not overwhelmed. The overlap time is about a few seconds is enough.

The control of the evaporator 36 installed in the cold water tank 30 is controlled as shown in FIG. 2 by the output of the aforementioned temperature control sensor 42 irrespective of the control of the freezing cycles of the first and second kimchi refrigerating chambers 26 and 28. That is, the solenoid valve 18c connected to the evaporator 36 is opened and closed to control the cooling cycle of the cold water purifier.

As described above, the present invention combines a cold water purifier and a kimchi refrigerator into a single product to efficiently control a refrigeration cycle, thereby reducing power consumption in the home, and utilizing the space of a kitchen by integrating a cold water purifier into the kimchi refrigerator. To maximize. In addition, by dispersing the refrigeration cycle of the kimchi refrigerator compartment and the cold water tank to distribute the evaporation load can reduce the capacity of the condenser can reduce the noise.
