The ice removing process of the ice making equipment is usually that the exhaust gas of the compressor is switched to flow in the direction of the evaporator, so that the high-temperature refrigerant directly flows into the evaporator without being cooled by the condenser, thereby increasing the temperature on the surface of the evaporator and melting the ice on the evaporator, so as to realize ice removing.

[0089] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0090] The following is combined with Figures 1 to 16 The following describes embodiments of the present invention.
[0091] According to an embodiment of the present invention, in one aspect, an evaporator structure 10 is provided for an ice-making device, including an evaporator body 1 and a support cover plate 2. The evaporator body 1 is located on top of the water tank 20 of the ice-making device and communicates with the water tank 20. The support cover plate 2 is connected to the evaporator body 1 and forms a receiving cavity 3 with the back of the evaporator body 1. The receiving cavity 3 is provided with a water inlet 31 and a water outlet 32. The water inlet 31 is located above the water outlet 32. The water inlet 31 is used to communicate with a room temperature water source, and the water outlet 32 is communicated with the water tank 20.
[0092] The evaporator body 1 and the bracket cover plate 2 surround the containing cavity 3, and the water inlet hole 31 of the containing cavity 3 is communicated with a normal-temperature water source. After the ice-making program of the ice-making device is completed and before the ice-removing program is started, normal-temperature water is injected into the containing cavity 3 through the water inlet hole 31. Since the normal-temperature water is usually about 20℃, the injected normal-temperature water can increase the temperature of the surface of the evaporator body 1 which is reduced due to the ice-making program, reduce the impact between the high temperature of the ice-removing program about to be started and the low temperature caused by the ice-making program, effectively solve the problem of cracks in ice blocks caused by cold and hot impact, and improve the quality of the ice blocks. At the same time, the normal-temperature water injected into the containing cavity 3 cooperates with the subsequent ice-removing program, so that the ice-removing temperature is more moderate and stable. In addition, the containing cavity 3 is provided with a water outlet hole 32 communicated with the water tank 20 of the ice-making device. The normal-temperature water is injected into the containing cavity 3 and enters the water tank 20 through the water outlet hole 32 at the same time. The water entering the water tank 20 can also be preliminarily cooled by the low temperature of the surface of the evaporator body 1, so as to shorten the ice-making time and improve the ice-making efficiency.
[0093] Specifically, in the embodiment, the low temperature usually refers to 0℃ or below, the temperature of the high-temperature exhaust gas is 70℃-90℃, and the temperature of the normal-temperature water of the normal-temperature water source is usually about 20℃.

In the direction perpendicular to the back of the evaporator body 1, the refrigeration pipeline 6 is staggered with the guide plate 5, so that an S-shaped flow channel is formed during the water flowing to the water outlet hole 32, thereby prolonging the flowing time of the water in the containing cavity 3 and prolonging the heat exchange time between the water and the evaporator body 1.
[0105] In a further embodiment, the two ends of the guide plate 5 in the length direction are close to the two side walls of the containing cavity 3, so that the water entering the water inlet hole 31 can be distributed along the length direction of the containing cavity 3 by the guiding effect of the guide plate 5.
[0106] In an embodiment, the refrigeration pipeline 6 includes at least two pipeline sections 61 arranged in sequence and spaced apart in the vertical direction, and a guide plate 5 is arranged between each two adjacent pipeline sections 61.

[0151] S33, if the switch structure 701 is triggered, it is considered that the ice contact strip 70 is rotated to be opened, and the ice removing valve 100 is controlled to be closed.
[0152] After the ice removing valve 100 is opened, the high-temperature and high-pressure refrigerant discharged by the compressor 90 directly enters the refrigeration pipeline 6 of the evaporator body 1 through the ice removing valve 100 and the control of the ice removing program without passing through the condenser 120 and the throttling device, at which time the high-temperature refrigerant transmits heat to the surface of the evaporator body 1 through the refrigeration pipeline 6, thereby melting the ice block contact surface and completing ice removing.

After the compressor 90 starts, the water inlet valve 50 is opened, which can preliminarily reduce the temperature of the water inlet during the water inlet process, shorten the ice making time, and improve the ice making efficiency. When the water level information reaches the first water level 201, the water inlet valve 50 is controlled to close to stop the water inlet, and the circulating water pump 30 is controlled to start to start ice making. The circulating water pump 30 sends the water in the water tank 20 to the evaporator body 1, and the water flowing through the evaporator body 1 exchanges heat with the evaporator surface and returns to the water tank 20 after cooling, until the water level information in the water tank 20 reaches the second water level 202, it is considered that most of the water has formed ice on the surface of the evaporator body 1, then the ice making program ends, and the ice making is completed, at this time the circulating water pump 30 is controlled to stop.
[0159] In the embodiment, the ice making process of the ice making device includes: firstly starting the compressor 90 to make the ice making device refrigerate, entering the ice making program, and starting to reduce the temperature of the evaporator body 1.

Finally, the water flows into the water tank 20. When the water level reaches the first water level 201, the water inlet valve 50 is powered off to cut off the water source. At this time, the circulating water pump 30 is started, and the circulating water pump 30 draws the water in the water tank 20 to flow into the water spraying pipe 12 at the top of the evaporator body 1 through the circulating pipeline, then passes through the ice grid 11 of the evaporator, and finally flows into the water tank 20 to realize ice making. When the water level decreases to the second water level 202, it is determined that the ice making program ends, and ice making is completed. At this time, the control circulating water pump 30 is stopped. Before entering the ice removing program, the water inlet valve 50 is powered on, and the normal-temperature water flows through the containing cavity 3 at the back of the evaporator body 1. The surface temperature of the evaporator body 1 increases. After 5-10 seconds, the ice removing valve 100 of the refrigeration is started to start the ice removing program, so that the influence of the high-temperature exhaust gas of the compressor 90 on the ice block on the ice grid 11 is avoided. When the water level is detected to reach the first water level 201, the water inlet valve 50 is disconnected, and the water inlet is stopped. At this time, the exhaust temperature of the compressor 90 also enters a stable state. The ice bumping strip 70 rotatable is arranged on the water tank 20, and the switch structure 701 is arranged on the ice bumping strip 70. When the whole ice block falls down, the ice bumping strip 70 is pressed, the ice bumping strip 70 rotates downward to trigger the switch structure 701. At this time, the ice removing valve 100 of the refrigeration device receives the information and is powered off to complete the ice removing.
