Description

Technical Field

[0001] This utility model relates to the field of tea bar machines, and in particular to a multifunctional tea bar machine control circuit with refrigerator preservation function. Background Technology

[0002] A tea bar machine can be considered an upgraded version of a water dispenser. It combines the functions of a water dispenser and a tea stove, yet differs from traditional water dispensers. Existing wooden tea bar machines have limited functionality. Customer feedback indicates that they only provide basic cooling and heating for drinking water, lacking refrigeration and preservation capabilities. For example, cold drinks and ice cream, which require refrigeration during gatherings, cannot be kept fresh. Therefore, in response to customer demand, our company designed a tea bar machine with a built-in refrigerator. During the integration of the refrigeration function, we discovered that adding a pre-made refrigerator directly into the tea bar machine would be inconvenient because it requires separate power and control, and cannot be centrally controlled via the tea bar machine's control panel. Therefore, our company conducted research and development to integrate a refrigerator with cooling and insulation functions into a customized tea bar machine. Through the design of the tea bar machine's circuit structure, we achieved unified drive and control.

[0003] During the research and development process, it was discovered that drinking water requires a refrigeration compressor during the cooling process, and the refrigeration of a refrigerator also requires a refrigeration compressor. If it could be controlled by a single refrigeration compressor, it would greatly save cabinet space and cost, while the refrigeration compressor of a finished refrigerator cannot be disassembled separately.

[0017] The present invention will be further described below.

The refrigeration evaporator in the cold tank 8 is used for cooling the cold water, and the refrigeration evaporator in the refrigerator 7 is used for refrigeration and preservation. The temperature sensor 10 in the cold tank 8 and the refrigerator 7 can detect their internal temperature so that the main control circuit board 1 of the tea bar machine can switch the three-way solenoid valve 6 according to the internal temperature.

At the same time, the main control circuit board 1 can switch the three-way solenoid valve 6 according to the temperature sensor 10 inside the cooling tank 8 and refrigerator compartment 7 to achieve separate cooling for the cooling tank 8 and refrigerator compartment 7. When the temperature of both the cooling tank 8 and refrigerator compartment 7 is high and both need to be cooled, the three-way solenoid valve 6 can be switched back and forth every five minutes to achieve separate cooling for the cooling tank 8 and refrigerator compartment 7. When a branch reaches the cooling temperature, the cooling of that branch can be stopped. When both the cooling tank 8 and refrigerator compartment 7 reach the set cooling temperature, the cooling of the refrigeration compressor 3 can be stopped.

[0021] This utility model designs a control circuit for the tea bar machine with refrigeration function developed by our company. It integrates two major functions, namely cooling water and fresh food preservation and refrigeration, on the basis of the original tea bar machine. Moreover, it can achieve the refrigeration of the refrigerator box 7 and the cold liner 8 simultaneously through only one refrigeration compressor 3 and condenser 5, which greatly saves equipment costs and increases the usable space of the tea bar machine.

The outlet end of the kettle water supply pipe 13 is connected to the inside of the kettle 15 through the water inlet coupler 14. The outlet end of the cold water supply pipe 16 is connected to the cold water outlet 17 through the cooling tank 8. A water pump 12 is provided on both the cold water supply pipe 16 and the kettle water supply pipe 13.

When the water temperature in the cold tank 8 reaches the set value, the refrigeration compressor 3 stops working. When the water temperature rises to the set maximum temperature, the refrigeration compressor 3 restarts to start refrigeration. The set standard temperature is: stop at 6℃, restart at 12℃. If the water temperature is 12℃ lower, the refrigeration compressor 3 does not work, and the refrigeration circuit of the refrigeration compressor 3 is in standby mode. (When the refrigeration of the cold tank 8 and the preservation of the refrigerator 7 are turned on at the same time, the flow direction of the refrigerant in the refrigerant refrigeration pipe 4 is switched by the opening and closing of the three-way solenoid valve 6, so that the refrigerant flows in the evaporator of the cold tank 8 and the refrigerator 7 for 5 minutes respectively, and continues to circulate until the temperature reaches the set value and the refrigeration circuit enters the standby state).

[0030] 2. Refrigerator Preservation: Connect the power supply, press the power button on control panel 2 to illuminate control panel 2, then press the refrigerator preservation button on control panel 2.

Compressor 3 will start working, and the three-way solenoid valve 6 will switch, allowing refrigerant to flow to the evaporator in refrigerator compartment 7. When the temperature inside refrigerator compartment 7 reaches the set value, compressor 3 will stop working. When the temperature rises to the set maximum temperature, compressor 3 will restart and begin refrigeration. The standard set temperature is: stop at 3℃, restart at 12℃. If the temperature is below 12℃, compressor 3 will not work, and the refrigeration circuit of compressor 3 will be in standby mode (when the cooling of the cold chamber 8 and the preservation of refrigerator compartment 7 are activated simultaneously, the flow of refrigerant in refrigerant pipe 4 is switched by the opening and closing of the three-way solenoid valve 6, allowing the refrigerant to flow in both the cold chamber 8 and the evaporator of refrigerator compartment 7 for 5 minutes each, continuously circulating until the temperature reaches the set value and the refrigeration circuit enters standby mode).
