Description

Technical Field

[0001] The present invention relates to the technical field of ice making equipment, and in particular to an evaporator structure, an ice making equipment, an ice making method and a computer-readable storage medium. Background Art

[0002] The ice-making process of ice-making equipment is usually to transport water from the water tank to the evaporator through a circulating water pump. The water flowing through the evaporator returns to the water tank after heat exchange with the refrigeration system, and circulates continuously until the water on the surface of the evaporator gradually forms an ice layer, thereby achieving ice making. The de-icing process of ice-making equipment is usually achieved by switching the exhaust flow direction of the compressor so that the high-temperature refrigerant flows directly into the evaporator without being cooled by the condenser, thereby increasing the temperature of the evaporator surface and melting the ice on the evaporator, thereby achieving de-icing.

[0003] When the existing ice-making equipment is defrosting, the high-temperature exhaust gas of the compressor instantly enters the evaporator. Since the temperature of the high-temperature exhaust gas is between 70℃ and 90℃, it is very easy to cause thermal shock to the ice cubes, causing cracks in the ice cubes and reducing the quality of the ice cubes. In addition, after the ice-making equipment enters the defrosting process, due to the resistance of the throttling device, the load of the compressor will decrease, and the exhaust gas temperature will first decrease and then slowly increase until it stabilizes. The temperature fluctuates greatly and is unstable. Summary of the invention

[0004] In view of this, the present invention provides an evaporator structure, an ice-making device, an ice-making method and a computer-readable storage medium to solve the problem that ice cubes are easily cracked when the ice-making device is defrosting, and the problem that the exhaust temperature fluctuates greatly and is unstable.

[0005] In a first aspect, the present invention provides an evaporator structure for an ice-making device, comprising:

[0006] an evaporator body, located on the top of the water tank of the ice-making device and communicated with the water tank;

[0007] The bracket cover is connected to the evaporator body and forms a accommodating cavity with the back side of the evaporator body. The accommodating cavity is provided with a water inlet hole and a water outlet hole. The water inlet hole is located above the water outlet hole. The water inlet hole is used to communicate with a normal temperature water source, and the water outlet hole is connected to the water tank.

[0008] Beneficial effects: The evaporator body and the bracket cover plate form a receiving chamber, and the water inlet of the receiving chamber is connected to the normal temperature water source. After the ice making process of the ice making equipment is completed and before the defrosting process is started, normal temperature water can be first injected into the receiving chamber through the water inlet. Since normal temperature water is usually around 20°C, the injected normal temperature water can increase the temperature of the surface of the evaporator body that is lowered due to the ice making process, reduce the impact between the high temperature of the defrosting process that is about to be started and the low temperature caused by the ice making process, effectively solve the problem of ice cracks caused by cold and hot shock, and improve the quality of ice; at the same time, the injection of normal temperature water into the receiving chamber in conjunction with the subsequent defrosting process can make the defrosting temperature milder and more stable. In addition, the receiving chamber is provided with a water outlet connected to the water tank of the ice making equipment. When the normal temperature water is injected into the receiving chamber, it enters the water tank through the water outlet, and the low temperature of the surface of the evaporator body can be used to preliminarily cool the water entering the water tank, shorten the ice making time, and improve the ice making efficiency.

[0009] In an optional embodiment, the water inlet hole is located at the top of the accommodating cavity, and the water outlet hole is located at the bottom of the accommodating cavity.

[0010] Beneficial effect: the water inlet hole is located at the top of the accommodating cavity, and the water outlet hole is located at the bottom. The water can flow downward from the top of the accommodating cavity under the action of its own gravity to pass through the back of the entire evaporator body, thereby heating the entire evaporator body.

[0011] In an optional embodiment, a water inlet chamber is further provided on the bracket cover, and the water inlet chamber is located on the top of the evaporator body. The water inlet chamber is connected with the accommodating chamber through the water inlet hole. A water inlet is provided on the water inlet chamber, and the water inlet is used to connect with a normal temperature water source.

[0012] Beneficial effect: The water inlet hole is connected to the normal temperature water source through the water inlet cavity and the water inlet. The normal temperature water source first enters the water inlet cavity and can first perform heat exchange from the top of the evaporator body; then enters the containing cavity through the water inlet hole and performs heat exchange from the back of the evaporator body. The setting of the water inlet cavity can increase the heat exchange area between the normal temperature water source and the evaporator body and improve the efficiency of heat exchange.

[0013] In an optional embodiment, the evaporator structure also includes a guide plate, which is arranged in the accommodating cavity and is located between the water inlet hole and the water outlet hole; the guide plate is connected to the bracket cover plate and extends downwardly and obliquely toward the back side of the evaporator body; a refrigeration pipe is provided on the back side of the evaporator body, and the refrigeration pipe and the guide plate are staggered in a direction perpendicular to the back side of the evaporator body.

[0014] Beneficial effects: The guide plate is connected to the bracket cover and extends downwardly and obliquely toward the back of the evaporator body, so as to guide the incoming water to the back of the evaporator body to improve the heat exchange effect between normal temperature water and the evaporator body; in the direction perpendicular to the back of the evaporator body, the refrigeration pipe and the guide plate are staggered, so that an S-shaped flow channel is formed in the process of water flowing toward the water outlet, which not only prolongs the flow time of water in the accommodating cavity, thereby prolonging the heat exchange time between the water and the evaporator body, but also can improve the temperature of the heat exchange pipe to a certain extent.

[0015] In an optional embodiment, the refrigeration pipeline includes at least two pipeline sections arranged in sequence and spaced apart in the vertical direction, and a guide plate is provided between every two adjacent pipeline sections.

[0016] Beneficial effect: At least two pipe sections are connected in sequence through at least two bending sections to form a whole refrigeration pipe. A guide plate is provided between every two adjacent pipe sections, which can further extend the flow channel between the water inlet and the water outlet, thereby extending the flow time of water in the accommodating cavity.

[0017] In an optional embodiment, the bracket cover is detachably connected to the evaporator body via fasteners.

[0018] Beneficial effects: It is easy to disassemble and install the support cover plate, and it is easy to maintain the support cover plate.

[0019] In an optional embodiment, an annular sealing portion is provided between the bracket cover and the evaporator body.

[0020] Beneficial effect: The provision of the annular sealing portion can achieve a sealed connection between the support cover and the evaporator body, thereby ensuring the sealing of the accommodating cavity.

[0021] In an optional implementation, the bracket cover is sealed and welded to the evaporator body.

[0022] Beneficial effect: The support cover plate is sealed and welded to the evaporator body, which can not only provide a relatively stable connection effect, but also ensure the sealing effect of the accommodating cavity.

[0023] In a second aspect, the present invention further provides an ice-making device, comprising:

[0024] The above-mentioned evaporator structure;

[0025] sink;

[0026] A circulating water pump connected to the evaporator body and the water tank through a circulating water path;

[0027] A water inlet pipe, one end of which is connected to the water inlet hole, and the other end of which is used to connect to a normal temperature water source;

[0028] A water inlet valve is arranged on the water inlet pipe.

[0029] In an optional embodiment, the ice-making device further includes a water level detection structure disposed in the water tank.

[0030] Beneficial effects: The water level detection structure can be used to detect the water level in the water tank, and control the opening or closing of the water inlet valve and / or the circulating water pump according to the water level in the water tank.

[0031] In an optional embodiment, it also includes an ice-breaking bar rotatably connected to the notch of the water tank, and a switch structure is provided on the ice-breaking bar.

[0032] Beneficial effect: The ice-blocking bar is rotatably connected to the notch of the water tank. When ice cubes on the evaporator body fall, they will press the ice-blocking bar, and the ice-blocking bar will rotate downward to trigger the switch structure. The ice-making equipment can control the ice-defrosting valve to close according to the signal of the switch structure, completing ice-defrosting, and the ice cubes fall into the water tank.

[0033] In a third aspect, the present invention further provides an ice-making method, which is used on the above-mentioned ice-making device; the ice-making method comprises:

[0034] Get progress information of ice making program;

[0035] If the progress information indicates that the ice making program is finished, the circulating water pump is controlled to stop running, the water inlet valve is controlled to open, and the normal temperature water from the normal temperature water source enters the containing chamber and the water tank in sequence through the water inlet pipe;

[0036] The opening time of the water inlet valve is obtained, and if the opening time reaches a preset time, the ice-making device is controlled to execute an ice-removing procedure.

[0037] Beneficial effect: after the ice making program ends and ice making is completed, the circulating water pump is controlled to stop running, and after the water inlet valve is controlled to open for a preset time, the ice making equipment is controlled to execute the defrosting program, so that the room temperature water source can enter the water tank through the water inlet pipe, the water inlet hole, the containing cavity, and the water outlet hole in sequence, which can be used to inject room temperature water into the containing cavity before entering the defrosting program, thereby increasing the temperature of the evaporator body surface that is lowered due to the ice making program, reducing the impact between the high temperature of the defrosting program that is about to be started and the low temperature caused by the ice making program, effectively solving the problem of cracks in ice cubes caused by cold and hot shocks, improving the quality of ice cubes, and making the defrosting temperature milder and more stable; it can also be used to inject water into the water tank, and the low temperature on the surface of the evaporator body is used to preliminarily cool the water entering the water tank, thereby shortening the ice making time and improving the ice making efficiency.

[0038] In an optional embodiment, after controlling the ice-making device to execute the deicing procedure, the method further includes:

[0039] Get the water level information in the tank;

[0040] If the water level information is the first water level, the water inlet valve is controlled to be closed.

[0041] Beneficial effect: The water inlet valve is controlled according to the water level information in the water tank. While the defrosting program is being executed, water can continue to flow into the water tank until the water level in the water tank reaches the first water level, which can meet the ice making needs of the next ice making program. The water inlet valve is then controlled to close.

[0042] In an optional implementation, the obtaining progress information of the ice-making program includes:

[0043] Get the water level information in the tank;

[0044] If the water level information is the second water level, the progress information indicates that the ice making program is finished, and the circulating water pump is controlled to stop;

[0045] Wherein, the first water level is higher than the second water level.

[0046] Beneficial effect: When the water level information in the water tank is the second water level, it means that most of the water in the water tank has formed ice cubes on the evaporator body, so the ice making program ends, and there is no need for a circulating water pump to continue circulating ice making.

[0047] In an optional implementation, the preset time is 5 seconds to 10 seconds.

[0048] Beneficial effect: The preset time is 5 to 10 seconds, which can provide enough time for the normal temperature water of the normal temperature water source to exchange heat with the evaporator body without taking up too much time for the defrosting program.

[0049] In an optional embodiment, the de-icing procedure includes:

[0050] Control the de-icing valve to open;

[0051] Get the trigger information of the switch structure;

[0052] If the switch structure is triggered, it is considered that the ice contact bar is rotated open, and the de-icing valve is controlled to be closed.

[0053] Beneficial effect: After the defrosting valve is opened, the high-temperature and high-pressure refrigerant discharged from the compressor enters the refrigeration pipe of the evaporator body directly through the control of the defrosting valve and the defrosting program without passing through the condenser and the throttling device. At this time, the high-temperature refrigerant transfers heat to the surface of the evaporator body through the refrigeration pipe, thereby melting the contact surface of the ice cubes and completing defrosting. When the ice cubes fall, they will press on the ice-contacting bar, and the ice-contacting bar will rotate downward, triggering the switch structure. The ice-making equipment can control the defrosting valve to close according to the signal of the switch structure, completing defrosting, and the ice cubes fall into the water tank.

[0054] In an optional embodiment, the ice making program includes:

[0055] The compressor is controlled to start, and the water inlet valve is controlled to open, so that the normal temperature water from the normal temperature water source enters the containing cavity and the water tank in sequence through the water inlet pipe;

[0056] Acquire water level information in the water tank, and if the water level information is a first water level, control the water inlet valve to close, and control the circulating water pump to start;

[0057] Continue to obtain the water level information in the water tank, if the water level information is the second water level, the ice making program ends, and the circulating water pump is controlled to stop;

[0058] Wherein, the first water level is higher than the second water level.

[0059] Beneficial effect: After the compressor is started, the compressor compresses the refrigerant, discharges the high-temperature and high-pressure refrigerant, cools it through the condenser, and becomes a refrigerant at normal temperature and high pressure. The refrigerant then enters the refrigeration pipe of the evaporator body through the throttling device, and becomes a low-temperature and low-pressure refrigerant at this time. After absorbing external heat for heat exchange, the refrigerant finally returns to the compressor. After the compressor is started, the water inlet valve is opened, and the temperature of the water inlet can be initially reduced during the water inlet process, shortening the ice making time and improving the ice making efficiency. When the water level information reaches the first water level, the water inlet valve is controlled to close to stop the water inlet, and the circulating water pump is controlled to start to start ice making. The circulating water pump transports the water in the water tank to the evaporator body. The water flowing through the evaporator body exchanges heat with the evaporator surface and cools down before returning to the water tank until the water level information in the water tank reaches the second water level. It is considered that most of the water has formed ice on the surface of the evaporator body, and the ice making program ends and the ice making is completed. At this time, the circulating water pump is controlled to stop.

[0060] In a fourth aspect, the present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and when the computer instructions are executed, the above-mentioned ice-making method is implemented.

[0061] Beneficial effects: The computer-readable storage medium provided by the present invention has all the technical effects of the above-mentioned ice-making method by adopting the ice-making method of the above-mentioned implementation method. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0090] Combine the following Figures 1 to 16 , describing an embodiment of the present invention.

[0091] According to an embodiment of the present invention, on the one hand, an evaporator structure 10 is provided for an ice-making device, including an evaporator body 1 and a bracket cover 2, wherein the evaporator body 1 is located at the top of a water tank 20 of the ice-making device and is connected to the water tank 20; the bracket cover 2 is connected to the evaporator body 1 and forms a receiving cavity 3 with the back side of the evaporator body 1, wherein the receiving cavity 3 is provided with a water inlet hole 31 and a water outlet hole 32, wherein the water inlet hole 31 is located above the water outlet hole 32, and the water inlet hole 31 is used to be connected to a normal temperature water source, and the water outlet hole 32 is connected to the water tank 20.

[0092] The evaporator body 1 and the bracket cover plate 2 form a receiving chamber 3, and the water inlet 31 of the receiving chamber 3 is connected to the normal temperature water source. After the ice making process of the ice making device is completed and before the de-icing process is started, normal temperature water can be first injected into the receiving chamber 3 through the water inlet 31. Since normal temperature water is usually around 20°C, the injected normal temperature water can increase the temperature of the surface of the evaporator body 1 that is reduced due to the ice making process, reduce the impact between the high temperature of the de-icing process that the evaporator is about to start and the low temperature caused by the ice making process, effectively solve the problem of ice cracks caused by cold and hot shock, and improve the quality of ice; at the same time, the injection of normal temperature water into the receiving chamber 3 in conjunction with the subsequent de-icing process can make the de-icing temperature milder and more stable. In addition, the receiving chamber 3 is provided with a water outlet 32 ​​connected to the water tank 20 of the ice making device. When the normal temperature water is injected into the receiving chamber 3, it enters the water tank 20 through the water outlet 32, and the low temperature on the surface of the evaporator body 1 can also be used to preliminarily cool the water entering the water tank 20, shortening the ice making time and improving the ice making efficiency.

[0093] Specifically, in this embodiment, low temperature generally refers to below 0°C, the temperature of high-temperature exhaust gas is between 70°C and 90°C, and the temperature of normal temperature water of the normal temperature water source is generally around 20°C.

The normal temperature water source first enters the water inlet cavity 4 and can first perform heat exchange from the top of the evaporator body 1; then enters the accommodating cavity 3 through the water inlet hole 31 and performs heat exchange from the back of the evaporator body 1. The provision of the water inlet cavity 4 can increase the heat exchange area between the normal temperature water source and the evaporator body 1 and improve the efficiency of heat exchange.

[0102] In a further embodiment, in order to facilitate better heat exchange between the water inlet chamber 4 and the evaporator body 1, at least part of the protrusion provided with the water inlet chamber 4 is located between the evaporator body 1 and the water spray pipe 12. The water spray pipe 12 is provided with a water spray hole at one end facing the protrusion, the top of the protrusion is inclined from the back to the front, and a flow balancing guide rib is also protruded on the protrusion, and the flow balancing guide rib is used to balance and guide the water sprayed from the water spray hole along the length direction of the water spray pipe 12, so that the water flow can flow evenly to each ice tray 11.

[0105] In a further embodiment, both ends of the guide plate 5 in the length direction are respectively close to the two side walls of the accommodating chamber 3 , so that water entering through a water inlet 31 can be distributed along the length direction of the accommodating chamber 3 through the guiding effect of the guide plate 5 .

[0106] In one embodiment, the refrigeration pipe 6 includes at least two pipe sections 61 arranged in sequence and at intervals along the vertical direction, and a guide plate 5 is provided between every two adjacent pipe sections 61 .

[0107] At least two pipe sections 61 are connected in sequence through at least two bending sections to form a whole refrigeration pipe 6. A guide plate 5 is provided between every two adjacent pipe sections 61, which can further extend the flow channel between the water inlet hole 31 and the water outlet hole 32, thereby extending the flow time of water in the accommodating chamber 3.

It can be used to inject normal temperature water into the accommodating chamber 3 before entering the defrosting program, increase the temperature of the surface of the evaporator body 1 that is reduced due to the ice making program, reduce the impact between the high temperature of the defrosting program that is about to start and the low temperature caused by the ice making program, effectively solve the problem of cracks in the ice cubes caused by the cold and hot shock, improve the quality of the ice cubes, and make the defrosting temperature more moderate and stable; it can also be used to inject water into the water tank 20, and use the low temperature on the surface of the evaporator body 1 to preliminarily cool the water entering the water tank 20, shorten the ice making time, and improve the ice making efficiency. The water inlet valve 50 is opened before the ice making process starts, and the room temperature water source can enter the water tank 20 through the water inlet pipe 40, the water inlet hole 31, the accommodating chamber 3, and the water outlet hole 32 in sequence, so as to store water in the water tank 20, so as to make ice with the water in the water tank 20. The circulating water pump 30 transports the water in the water tank 20 to the water spray pipe 12 through the circulating water circuit 301, and the water is transported to the evaporator body 1 by the water spray pipe 12. The water flowing through the evaporator body 1 returns to the water tank 20 after heat exchange with the refrigeration system.

[0119] In one embodiment, the ice-making device further includes a water level detection structure 60 disposed in the water tank 20 .

[0120] The water level detection structure 60 can be used to detect the water level in the water tank 20 , and control the opening or closing of the water inlet valve 50 and / or the circulating water pump 30 according to the water level in the water tank 20 .

[0121] In a specific embodiment, if the water level in the water tank 20 reaches the first water level 201, it can be considered that enough water to be refrigerated has been injected into the water tank 20, and the water inlet valve 50 can be closed at this time to stop the water inlet; if it is in the ice making program, the circulating water pump 30 can be started to start ice making; if it is in the ice defrosting program, the circulating water pump 30 can be not started first, and the circulating water pump 30 can be started after the ice defrosting program is finished. If the water level in the water tank 20 reaches the second water level 202, it can be considered that the water in the water tank 20 is insufficient, the ice making program is over, and ice making is completed. At this time, the circulating water pump 30 is closed, and the water inlet valve 50 is started to let water in. The first water level 201 is higher than the second water level 202. The first water level 201 is the high water level in the water tank 20, and the second water level 202 is the low water level in the water tank 20.

[0122] In one embodiment, an ice-breaking bar 70 is further included, which is rotatably connected to the notch of the water tank 20 , and a switch structure 701 is provided on the ice-breaking bar 70 .

[0123] The ice-impinging bar 70 is rotatably connected to the notch of the water tank 20. When ice cubes on the evaporator body 1 fall off, they will press on the ice-impinging bar 70. The ice-impinging bar 70 rotates downward, triggering the switch structure 701. The ice-making equipment can control the ice-defrosting valve 100 to close according to the signal of the switch structure 701, completing ice-defrosting, and the ice cubes fall into the water tank 20.

[0124] In a specific implementation, the switch structure 701 may be a proximity switch.

[0125] In a specific implementation, the ice-making equipment also includes a drain pipe and a drain valve 80. The drain pipe is provided with a drain valve 80. The drain pipe can be connected to the circulating water circuit 301 and connected to the water tank 20 through the circulating water circuit 301. It can also be directly connected to the water tank 20. When the drain valve 80 is opened, the water in the water tank 20 can be discharged.

[0126] In this embodiment, the ice making device further includes a compressor 90, an ice-defrosting valve 100, a flow collecting device 110, a condenser 120 and a condensing fan 130. The compressor 90 includes a process pipe 901, an air intake pipe 902 and an air discharge pipe 903. In the refrigeration process, the compressor 90 compresses the refrigerant, discharges the high-temperature and high-pressure refrigerant, cools it through the condenser 120, and turns it into a refrigerant at room temperature and high pressure. The refrigerant then enters the refrigeration pipe 6 of the evaporator body 1 through the throttling device, and at this time it becomes a low-temperature and low-pressure refrigerant. After absorbing external heat for heat exchange, the refrigerant finally returns to the compressor 90. In the ice-defrosting process, the high-temperature and high-pressure refrigerant discharged from the compressor 90 directly enters the refrigeration pipe 6 of the evaporator body 1 through the control of the ice-defrosting valve 100 and the ice-defrosting process without passing through the condenser 120 and the throttling device. At this time, the high-temperature refrigerant transfers heat to the surface of the evaporator body 1 through the refrigeration pipe 6, thereby melting the contact surface of the ice cubes and completing ice-defrosting.

[0127] In this embodiment, the water inlet valve 50 may be a solenoid valve, the water discharge valve 80 may be a solenoid valve, and the ice removal valve 100 may be a solenoid valve.

[0128] According to an embodiment of the present invention, on the other hand, an ice-making method is also provided, which is used on the above-mentioned ice-making equipment, and the ice-making equipment includes the above-mentioned evaporator structure 10, water tank 20, circulating water pump 30, water inlet pipe 40 and water inlet valve 50; the circulating water pump 30 is connected to the evaporator body 1 and the water tank 20 through a circulating water circuit 301; one end of the water inlet pipe 40 is connected to the water inlet hole 31, and the other end is used to connect to a normal temperature water source; the water inlet valve 50 is arranged on the water inlet pipe 40. The evaporator structure 10 includes an evaporator body 1 and a bracket cover 2. The evaporator body 1 is located on the top of the water tank 20 of the ice-making device and is connected to the water tank 20. The bracket cover 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 normal temperature water source. The water outlet 32 ​​is connected to the water tank 20. The ice-making method includes:

[0129] S1, obtaining progress information of ice making program;

[0130] S2. If the progress information indicates that the ice making program is finished, the circulating water pump 30 is controlled to stop running, the water inlet valve 50 is controlled to open, and the normal temperature water from the normal temperature water source enters the containing chamber 3 and the water tank 20 in sequence through the water inlet pipe 40;

[0131] S3, obtaining the opening time of the water inlet valve 50, and if the opening time reaches a preset time, controlling the ice-making device to execute an ice-removing procedure.

[0132] After the ice making program ends and ice making is completed, the circulating water pump 30 is controlled to stop running, and after the water inlet valve 50 is controlled to open for a preset time, the ice making equipment is controlled to perform the defrosting program, so that the room temperature water source can enter the water tank 20 through the water inlet pipe 40, the water inlet hole 31, the accommodating chamber 3, and the water outlet hole 32 in sequence. It can be used to inject room temperature water into the accommodating chamber 3 before entering the defrosting program, increase the temperature of the surface of the evaporator body 1 that is reduced due to the ice making program, reduce the impact between the high temperature of the defrosting program that is about to be started by the evaporator and the low temperature caused by the ice making program, effectively solve the problem of cracks in the ice caused by the cold and hot shock, improve the quality of the ice, and make the defrosting temperature more moderate and stable; it can also be used to inject water into the water tank 20, and use the low temperature on the surface of the evaporator body 1 to preliminarily cool the water entering the water tank 20, shorten the ice making time, and improve the ice making efficiency.

[0133] In one embodiment, after controlling the ice-making device to execute the deicing procedure, the method further includes:

[0134] S4, obtaining water level information in the water tank 20;

[0135] S5. If the water level information is the first water level 201, control the water inlet valve 50 to close.

[0136] The water inlet valve 50 is controlled according to the water level information in the water tank 20. While the defrosting program is being executed, the water continues to flow into the water tank 20 until the water level in the water tank 20 reaches the first water level 201, which is sufficient for ice making in the next ice making program. The water inlet valve 50 is then controlled to close.

[0137] In one embodiment, obtaining progress information of the ice-making program includes:

[0138] S11, obtaining water level information in the water tank 20;

[0139] S12, if the water level information is the second water level 202, the progress information indicates that the ice making program is finished, and the circulating water pump 30 is controlled to stop;

[0140] The first water level 201 is higher than the second water level 202 .

[0141] When the water level information in the water tank 20 is the second water level 202, it means that most of the water in the water tank 20 has formed ice cubes on the evaporator body 1, so the ice making program ends, and the circulating water pump 30 is not needed to continue circulating ice making.

[0142] Specifically, if the water level in the water tank 20 reaches the first water level 201, it can be considered that enough water to be refrigerated has been injected into the water tank 20, and the water inlet valve 50 can be closed to stop the water from entering; if it is in the ice making program, the circulating water pump 30 can be started to start ice making; if it is in the ice defrosting program, the circulating water pump 30 can be not started first, and the circulating water pump 30 can be started after the ice defrosting program is finished. If the water level in the water tank 20 reaches the second water level 202, it can be considered that the water in the water tank 20 is insufficient, the ice making program is finished, and ice making is completed. At this time, the circulating water pump 30 is closed, and the water inlet valve 50 is started to let water in. The first water level 201 is higher than the second water level 202. The first water level 201 is the high water level in the water tank 20, and the second water level 202 is the low water level in the water tank 20.

[0143] In one embodiment, the preset time is 5 seconds to 10 seconds.

[0144] The preset time is 5 to 10 seconds, which can provide enough time for the normal temperature water of the normal temperature water source to exchange heat with the evaporator body 1 without taking up too much time for the defrosting procedure.

[0145] In a specific embodiment, the preset time is 5 seconds.

[0146] Specifically in another embodiment, the preset time is 10 seconds.

[0147] Specifically in another embodiment, the preset time is 7.5 seconds.

[0148] In one embodiment, the de-icing procedure includes:

[0149] S31, controlling the de-icing valve 100 to open;

[0150] S32, obtaining trigger information of the switch structure 701;

[0151] S33: If the switch structure 701 is triggered, it is considered that the ice contact bar 70 is rotated to open, and the ice removal valve 100 is controlled to be closed.

[0152] After the defrosting valve 100 is opened, the high-temperature and high-pressure refrigerant discharged from the compressor 90 enters the refrigeration pipe 6 of the evaporator body 1 directly through the defrosting valve 100 and the defrosting program without passing through the condenser 120 and the throttling device. At this time, the high-temperature refrigerant transfers heat to the surface of the evaporator body 1 through the refrigeration pipe 6, thereby melting the contact surface of the ice cubes and completing defrosting. When the ice cubes fall, they will press on the ice-impacting bar 70, and the ice-impacting bar 70 will rotate downward, triggering the switch structure 701. The ice-making equipment can control the defrosting valve 100 to close according to the signal of the switch structure 701, completing defrosting, and the ice cubes fall into the water tank 20.

[0153] In one embodiment, the ice making program includes:

[0154] S101, control the compressor 90 to start, and control the water inlet valve 50 to open, so that the normal temperature water from the normal temperature water source enters the accommodating chamber 3 and the water tank 20 in sequence through the water inlet pipe 40;

[0155] S102, obtaining water level information in the water tank 20, if the water level information is the first water level 201, controlling the water inlet valve 50 to close, and controlling the circulating water pump 30 to start;

[0156] S103, continue to obtain the water level information in the water tank 20, if the water level information is the second water level 202, the ice making program ends, and the circulating water pump 30 is controlled to stop;

[0157] The first water level 201 is higher than the second water level 202 .

[0158] After the compressor 90 is started, the compressor 90 compresses the refrigerant, discharges the high-temperature and high-pressure refrigerant, cools it through the condenser 120, and becomes a refrigerant at normal temperature and high pressure. The refrigerant then enters the refrigeration pipe 6 of the evaporator body 1 through the throttling device, and becomes a low-temperature and low-pressure refrigerant at this time. After absorbing external heat for heat exchange, the refrigerant finally returns to the compressor 90. After the compressor 90 is started, the water inlet valve 50 is opened, and the temperature of the water inlet can be initially reduced during the water inlet process, shortening the ice making time and improving the ice making efficiency. When the water level information reaches the first water level 201, the water inlet valve 50 is controlled to be closed to stop the water inlet, and the circulating water pump 30 is controlled to start to start ice making. The circulating water pump 30 transports the water in the water tank 20 to the evaporator body 1. The water flowing through the evaporator body 1 exchanges heat with the evaporator surface and cools down, and then returns to the water tank 20 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, and 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 this embodiment, the ice-making process of the ice-making device includes: first, the compressor 90 is started to refrigerate the ice-making device and enter the ice-making program. The temperature of the evaporator body 1 begins to decrease. At this time, the water inlet valve 50 is started, and the ambient temperature water source flows continuously through the accommodating chamber 3 on the back of the evaporator body 1 through the water inlet valve 50 to initially cool the water. 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 water from the water tank 20 through the circulating pipeline and flows into the water spray pipe 12 at the top of the evaporator body 1, and then flows through the ice tray 11 of the evaporator, and finally flows into the water tank 20 to achieve ice making. When the water level drops to the second water level 202, it can be determined that the ice-making program is over and ice making is completed. At this time, the circulating water pump 30 is controlled to stop. Before entering the defrosting procedure, the water inlet valve 50 is energized, and normal temperature water flows through the accommodating chamber 3 on the back of the evaporator body 1. The surface temperature of the evaporator body 1 rises. After 5 to 10 seconds, the refrigeration defrosting valve 100 is started again to start the defrosting procedure, thereby avoiding the high temperature exhaust of the compressor 90 from causing instantaneous cold and heat shock to the ice cubes on the ice tray 11. When the water level detection reaches the first water level 201, the water inlet valve 50 is disconnected to stop the water inlet. At this time, the exhaust temperature of the compressor 90 also enters a stable state. A rotatable ice-collision bar 70 is provided on the water tank 20, and a switch structure 701 is provided on the ice-collision bar 70. When the entire surface of ice cubes falls, it will press the ice-collision bar 70, and the ice-collision bar 70 will rotate downward, triggering the switch structure 701. At this time, the defrosting valve 100 of the refrigeration equipment receives the information, and the power will be cut off to complete the defrosting.
