[0012] 1、The three -way ice maker evaporator structure can more effectively adjust the refrigeration effect and efficiency in the evaporator by precisely controlling the ice making valve to distribute the refrigerant flow in the two capillary tubes. This flow control helps to optimize the circulation of refrigerant in the system, reduces unnecessary energy consumption, and achieves energy saving effect. Since two capillary tubes are provided and the ice making valve can control the refrigerant flow in each of them, two different evaporation temperature zones can be realized in the evaporator. This design is particularly useful in situations where different refrigeration requirements are needed, such as rapid ice making and maintaining the stable low temperature state of ice blocks, improving the flexibility and applicability of the ice maker. The low temperature refrigerant flowing in the evaporator evaporator pipe can quickly absorb the heat of the surrounding water, promoting rapid ice formation. At the same time, the heat dissipation and compression process of the refrigerant in the condenser and compressor ensures that the refrigerant can continuously return to the evaporator in a low temperature and high pressure state, thereby maintaining efficient ice making circulation. By precisely controlling the flow and evaporation temperature of the refrigerant, the system can better adapt to changes in external environment, such as changes in environmental temperature, humidity and other factors, thereby maintaining stable refrigeration effect and ice making efficiency.

[0021] When the ice maker is in the ice making state, the low-temperature refrigerant flows in the evaporator evaporation pipe 143 in the evaporator 14, water enters the evaporator 14 and exchanges heat with the refrigerant, the refrigerant absorbs heat and enters the condenser 12 and the compressor 13 to dissipate heat and compress, and then is controlled by the refrigeration valve 11, and the low-temperature high-pressure refrigerant is again introduced into the evaporator inlet 141 in the evaporator 14 from the capillary tube 111, at this time, the capillary tube 111 is replaced from the narrow space into the evaporator inlet 141, the volume of the pipeline increases, the low-pressure refrigerant vaporizes and absorbs heat, so that the temperature of the evaporator evaporation pipe 143 decreases, and the capillary tube 111 is provided with two, by controlling the flow, the two evaporation temperatures in the evaporator 14 can be controlled.

[0022] The condenser 12 is arranged on the upper side of the back of the ice maker 1, the compressor 13 is arranged on the inner bottom of the ice maker 1, and the evaporator 14 is arranged at the same height as the condenser 12 and is installed on the inner bottom of the ice maker 1. This layout helps to reduce the center of gravity and improve the stability of the ice maker. At the same time, the bottom installation also facilitates the maintenance personnel to check and repair the compressor. The evaporator 14 is horizontally arranged at the same height as the condenser 12. Such design can make the flow of refrigerant in the system more smooth, and reduce the additional pressure loss caused by the height difference. The ice making valve 11 is arranged beside the compressor 13, and the capillary tube 111 at the outlet of the ice making valve 11 is arranged in an upward extending manner. The ice making valve 11 is arranged beside the compressor 13, and the capillary tube 111 at the outlet of the ice making valve 11 extends upward. Such layout can ensure that the refrigerant can smoothly enter the evaporator after passing through the ice making valve, and at the same time, avoid the pressure loss caused by the bending or excessive stretching of the capillary tube.

The evaporator 14 is provided with an evaporator inlet 141 and an evaporator outlet 142, and the two capillary tubes 111 enter the evaporator inlet 141. The refrigerant flows from the evaporator inlet 141 into the evaporator tube 143 in the evaporator 14, and flows out from the evaporator outlet 142.

The low-pressure refrigerant vaporizes and absorbs heat, so that the temperature of the evaporator tube 143 decreases. At the same time, the capillary tube 111 is provided with two capillary tubes. By controlling the flow, the evaporator 14 can control two evaporation temperatures.
