The high-efficiency de-icing type evaporator includes a shell, an evaporator body, and an ice block removal unit. The shell is used for assembly and connection with external equipment. The evaporator body is located inside the shell and is used for the ice-making process. The ice block removal unit is located on one side of the evaporator body and is used to assist in the removal of ice blocks. Through the ice block removal unit, while the medium pipe is removing ice, the vortex tube is driven to perform hot and cold flow separation of compressed air. The hot airflow is evenly sprayed onto the back of the evaporator body through the spray seat to achieve uniform heating of the whole.

Description

Technical Field

[0001] This invention relates to the field of ice-making equipment technology, specifically to a high-efficiency de-icing type ice maker evaporator and its method. Background Technology

[0002] Ice-making equipment is an automated refrigeration system that rapidly freezes water into blocks, flakes, tubes, and other forms of ice. It is widely used in catering, supermarkets, fisheries, medical and industrial cooling. It has the advantages of fast ice-making speed, clean and uniform ice blocks, fully automatic operation, energy and water saving, and simple operation. It can stably and continuously supply ice, greatly improve ice efficiency and hygiene standards, replace traditional manual ice making, save time and labor, and adapt to different scenario needs.

[0003] However, the existing ice machine evaporators have the following shortcomings: 1. Traditional devices use a single heat exchange structure, relying solely on serpentine medium pipes to transport heat medium for de-icing and heating. The heat decreases gradually along the pipes, resulting in uneven heating in different areas of the evaporator, asynchronous de-icing, and uneven ice discharge.

[0004] 2. After the ice is de-iced, the next ice-making cycle begins directly. The residual water film on the inner wall of the ice tray is not removed, resulting in abnormal adhesion between the ice and the metal wall and uneven freezing. Long-term use can easily lead to scaling, which affects the de-icing effect.

[0005] To address the shortcomings of existing technologies, this invention provides a high-efficiency de-icing type ice maker evaporator and its method to solve the aforementioned problems. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides an efficient de-icing type evaporator for ice makers and its method, solving the problem of uneven ice detachment caused by ice-making equipment relying solely on heat transfer through a medium pipe for heating and de-icing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency de-icing type ice maker evaporator and its method, comprising: Housing, used for assembly and connection with external equipment; The evaporator body is located inside the shell and is used for the ice-making process; An ice removal unit is located on one side of the evaporator body and is used to assist in the removal of ice. The ice-making and demolding integrated unit is located on one side of the evaporator body and is used to perform ice-making, molding, and demolding actions. The control unit, located on one side of the housing, is used to receive sensor signals and perform coordinated control of each actuator. The ice removal unit includes an installation groove formed on the outer wall of the evaporator body. A temperature sensing block for transmitting temperature is installed on the inner wall of the installation groove. A deformation plate for pushing the ice block out of the mold is fitted on the outer wall of the temperature sensing block. There are multiple deformation plates, and their outer surfaces are on the same plane as the outer surface of the evaporator body.

[0008] Preferably, the ice removal unit further includes a spray seat installed at the top of the housing, the output end of the spray seat is stepped and the spray covers the outer wall of the evaporator body, and the input end of the spray seat is equipped with a pipe.

[0009] Preferably, a vortex tube for flow diversion is installed on the upper end face of the housing, the hot flow end of the vortex tube is threadedly connected to the pipe fitting, an air inlet pipe is installed at the input end of the vortex tube, and a solenoid valve is installed at the end of the air inlet pipe.

[0010] Preferably, the control unit includes an integrated controller, a data acquisition module, and a temperature sensing module. The integrated controller is connected to the control terminal of the evaporator body and the solenoid valve signal on the outer wall of the vortex tube, respectively. The data acquisition module is installed on the lower end face of the housing, and the temperature sensing module is installed on the outer surface of the evaporator body.

[0011] Preferably, the ice removal unit further includes a purge seat fixedly connected to the outer surface of the housing, and the output end of the purge seat is provided with a purge nozzle, and a plurality of the purge nozzles are inclined and correspond to the outer surface of the evaporator body.

[0012] Preferably, a purge pipe is installed at the input end of the purge seat, the end of the purge pipe is installed at the cold air end of the vortex tube, and an electrically controlled valve is installed on the outer wall of the purge pipe.

[0013] Preferably, the integrated desiccant unit includes a medium pipe installed on the outer surface of the evaporator body, with control valves installed at the input and output ends of the medium pipe, and a water distribution plate installed inside the housing on one side of the evaporator body, with the output end of the water distribution plate corresponding to the outer surface of the evaporator body.

[0014] Preferably, the outer wall of the pipe fitting is equipped with a waste heat recovery pipe, and there are multiple waste heat recovery pipes with heat conduction valves installed at their ends.

[0015] Preferably, the inner and outer walls of the housing are equipped with snap-fit ​​strips, and the number of snap-fit ​​strips is several, with a snap-fit ​​groove on the outer wall.

[0016] This invention also discloses a high-efficiency de-icing ice maker evaporator and its method, applied to the aforementioned high-efficiency de-icing ice maker evaporator, comprising the following steps: S1, Ice making starts. By starting the evaporator body and the integrated ice making and ice removal unit, water is continuously sprayed through the water distribution plate, and then ice is made through the evaporator body. S2, Ice making completion judgment: Through the settings of the temperature sensing module and the acquisition module in the control unit, multiple temperature sensing modules on the outer wall of the evaporator body are used to collect the ice making threshold at multiple points. With the image acquisition and recognition of the acquisition module, it is determined whether the ice blocks in the multiple ice compartments of the evaporator body have been prepared. S3, De-icing begins. After receiving the signal, the integrated controller starts the evaporator body and solenoid valve. The heat medium is introduced through the medium pipe to achieve rapid heating. Simultaneously, compressed air is sent into the vortex tube and separated into hot and cold airflows. The hot airflow is evenly sprayed onto the back of the evaporator body through the spray seat to heat it up and de-ice it. When the temperature reaches the bending threshold of the deformation plate, the deformation plate bends and pushes the ice block to achieve assisted de-icing. S4, residual water film purging: After de-icing is completed, the acquisition module acquires an image of the evaporator body surface to determine whether all detachment is complete. Once detachment is complete, the solenoid valve of the vortex tube cold flow is opened, and the outer surface of the evaporator body is purged with cold flow through the purging seat and several purging nozzles to remove the residual water film on its surface. At the same time, the deformation plates are reset by low temperature.

[0017] The technical effects and advantages of this invention are as follows: This high-efficiency de-icing ice maker evaporator and its method, by setting up an ice block detachment unit, simultaneously drives the vortex tube to split the compressed air into hot and cold streams while the heat medium is delivered through the medium pipe for de-icing. The hot airflow is evenly sprayed onto the back of the evaporator body through the spray seat, achieving uniform heating and improving the uniformity of de-icing. At the same time, the temperature sensing block quickly absorbs and transfers heat. When the temperature reaches the deformation threshold of the deformation plate, the deformation plate immediately bends and pushes the ice block from the back where the adhesion is strongest and the ice block is most difficult to detach, so that the ice block can be quickly separated from the ice mold. This structure can improve the de-icing speed and ice block integrity through the dual action of airflow heating and mechanical pushing, and reduce the phenomenon of broken ice and ice jamming.

[0018] By configuring a control unit, and utilizing the collaborative work of the acquisition module, integrated controller, and multi-point temperature sensing module, the acquisition module can perform real-time image acquisition of the ice grid area of ​​the evaporator body to intuitively determine whether the ice-making process is complete. At the same time, the temperature sensing module located on the back of the evaporator performs multi-point temperature acquisition to obtain more comprehensive temperature change data. Multiple signals are synchronously transmitted to the integrated controller for comprehensive judgment, improving the accuracy and reliability of the ice-making completion judgment. The integrated controller then uniformly controls and automatically starts the de-icing, purging, and next cycle ice-making processes, realizing intelligent linkage and automated operation throughout the entire process.

[0019] 3. After the control unit makes a judgment based on the system operating conditions, it stably delivers the low-temperature cold airflow generated by the vortex tube to multiple purging nozzles through the purge pipe. Each nozzle adopts an inclined directional arrangement, so that multiple streams of cold air accurately and evenly cover the entire surface of the ice grid of the evaporator body. The high-speed cold airflow can efficiently purge and thoroughly remove the water film remaining on the inner wall of the ice grid, avoid water stains adhering to local water accumulation, provide a clean and dry ice mold environment for the next ice making cycle, effectively reduce the probability of scale adhesion, improve the adhesion between the ice body and the ice grid, and enhance the stability of continuous ice making.

[0023] 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, and 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.

[0024] This embodiment discloses a high-efficiency de-icing type ice maker evaporator, according to the attached... Figure 1 To be continued Figure 6 As shown, it includes: Housing 1, used for assembly and connection with external equipment; The evaporator body 2 is located inside the shell 1 and is used for the ice-making process. Ice removal unit 3 is located on one side of evaporator body 2 and is used to assist in the removal of ice. The ice-making and demolding integrated unit 4 is located on one side of the evaporator body 2 and is used to perform ice-making, molding and demolding actions; The control unit 5, located on one side of the housing 1, is used to receive sensor signals and perform linkage control on each actuator. The ice removal unit 3 includes an installation groove 301 on the outer wall of the evaporator body 2. The inner wall of the installation groove 301 is equipped with a temperature sensing block 302 for transmitting temperature. The outer wall of the temperature sensing block 302 is equipped with a deformation plate 303 for pushing the ice block to release it. There are multiple deformation plates 303, and their outer surfaces are on the same plane as the outer surface of the evaporator body 2. Both the inner and outer walls of the housing 1 are equipped with snap-fit ​​strips 101, and there are several snap-fit ​​strips 101, with a snap-fit ​​groove on the outer wall; The housing 1 provides sufficient installation support for the evaporator body 2 and also facilitates quick connection with external ice-making equipment. The multiple snap-fit ​​strips 101 installed on the inner and outer walls of the housing 1 can quickly and flexibly connect with external ice-making equipment, thereby maintaining the stability of the evaporator body 2 during operation. By cooperating with the evaporator body 2 and the integrated ice-making and de-icing unit 4, and under the unified linkage of the control unit 5, relying on multi-dimensional data acquisition and intelligent judgment, the reversing valve is precisely controlled to complete the directional delivery of refrigerant and heat medium, enabling the evaporator body 2 to efficiently perform the switching process of ice making and de-icing. At the same time, with the help of the independent ice removal unit 3, a high-speed high-temperature airflow is introduced to blow a large area of ​​the back area of ​​the evaporator body 2, and the external hot airflow is used to enhance the de-icing process. This method can effectively make up for the problems of heat attenuation and uneven distribution in the traditional serpentine medium pipe 401 during the heat medium delivery process, reduce pipeline heat loss and regional temperature difference, make the evaporator body 2 more uniformly heated, and avoid the phenomenon of de-icing delay, ice block sticking or even ice jam caused by insufficient local temperature, thus improving the de-icing stability and overall working efficiency. The outer wall of the evaporator body 2 has a dedicated mounting groove 301, which can realize the stable assembly of the temperature sensing block 302, ensuring that it maintains a stable and reliable contact state under alternating high and low temperature conditions, and avoiding loosening that affects the heat transfer efficiency. The temperature sensing block 302 is made of a high thermal conductivity material, which can quickly absorb the heat of the high hot airflow and evenly conduct it to the inside, so that the multiple deformable plates 303 arranged in close contact are heated simultaneously. The deformation plate 303 is made of bimetallic composite material. When the temperature rises to the set deformation threshold, it will bend and deform in a directional direction towards the ice block. Through mechanical pushing, it directly acts on the root position where the ice block is most tightly bound to the ice grid and is most difficult to detach, actively loosening and peeling off the adhered ice. This structure combines thermal induction with passive mechanical pushing, effectively improving the problems of incomplete ice removal and easy ice jamming and breaking in traditional methods, and improving the efficiency and integrity of ice removal.

[0025] The ice removal unit 3 also includes a jet seat 304 installed at the top of the housing 1. The output end of the jet seat 304 is stepped, and the jet covers the outer wall of the evaporator body 2. A pipe fitting 305 is installed at the input end of the jet seat 304. A vortex tube 306 for diverting flow is installed on the upper end face of the housing 1. The hot flow end of the vortex tube 306 is threadedly connected to the pipe fitting 305. An air inlet pipe 312 is installed at the input end of the vortex tube 306. A solenoid valve 307 is installed at the end of the air inlet pipe 312. The jet seat 304 can be used in conjunction with the pipeline to quickly guide the high-speed airflow at the hot flow end of the vortex tube 306. By using an inclined and directional jet seat 304, the output end can accurately guide the airflow at an angle, so that the airflow can spread evenly along the surface of the evaporator body 2, fully covering all areas of the evaporator body 2 and several temperature sensing blocks 302 fixedly mounted on its outer wall, avoiding the situation of concentrated airflow and uneven local heating, laying the foundation for uniform de-icing in the future. The back of the temperature sensing block 302 is specially provided with fine capillary grooves. The capillary grooves can effectively increase the heat exchange contact area and accelerate the heat conduction speed of the high-temperature airflow, so that the temperature sensing block 302 can quickly absorb heat and transfer it to the deformation plate 303, which greatly shortens the response time of the deformation plate 303 and improves the timeliness of mechanical jacking to remove ice. Meanwhile, an air intake pipe 312 is fixedly installed at the input end of the vortex tube 306. The air intake pipe 312 works in conjunction with the solenoid valve 307 linked to the control unit 5. When the control unit 5 issues a de-icing command, the solenoid valve 307 opens quickly to guide the high-speed compressed air generated by the external air compressor, avoiding airflow stagnation or leakage. The air intake pipe 312 is stably connected to the vortex tube 306 through a sealed pipeline, which can stably and efficiently deliver high-speed compressed air to the inside of the vortex tube 306, ensuring stable airflow pressure and smooth delivery. With its unique internal vortex cavity structure, the vortex tube 306 forms a high-speed rotating vortex inside the cavity when high-speed compressed air enters. Utilizing the principle of centrifugal force and energy exchange, the single compressed air is split into two airflows with different properties: a high-temperature airflow and a high-temperature cold airflow. The high-temperature airflow is output through the large end of the vortex tube 306 and transported to the jet seat 304 through the fitting 305. Finally, it is rapidly and evenly ejected from the inclined output end of the jet seat 304, providing a continuous, high-speed, and evenly distributed high-temperature airflow for the de-icing process of the evaporator body 2, effectively enhancing the de-icing effect and improving the de-icing efficiency.

[0026] The control unit 5 includes an integrated controller 501, a data acquisition module 502, and a temperature sensing module 503. The integrated controller 501 is connected to the control terminal of the evaporator body 2 and the solenoid valve 307 on the outer wall of the vortex tube 306. The data acquisition module 502 is installed on the lower end face of the housing 1, and the temperature sensing module 503 is installed on the outer surface of the evaporator body 2. By using the control unit 5, multiple devices can be linked together to maintain the high efficiency of ice making and ice removal. To achieve precise control of the ice-making and de-icing processes, the equipment is equipped with a data acquisition module 502 and a temperature sensing module 503 working together: the data acquisition module 502 can acquire real-time images of the ice grid area on the outer wall of the evaporator body 2. It can use compatible devices such as industrial global shutter cameras, 3D depth cameras and line laser 3D contour sensors. These devices can stably capture image information such as the ice-forming state and surface residue in the ice grid, and transmit the acquired image data to the integrated controller 501 in real time to meet the controller's requirements for judging the ice-making and de-icing states. Meanwhile, multiple temperature sensing modules 503 are evenly installed on the outer surface of the evaporator body 2. Through multi-point synchronous acquisition, the refrigeration temperature during the ice-making stage and the heating temperature during the de-icing stage are accurately captured, further improving the data judgment basis of the integrated controller 501. The temperature sensing modules 503 transmit the collected multi-point temperature data to the integrated controller 501 in real time, complementing the image data. This enables the integrated controller 501 to accurately determine the ice-making completion status and the de-icing completion status, ensuring the integrity of data acquisition and improving the accuracy of equipment operation, thus ensuring the orderly and efficient progress of the ice-making and de-icing processes.

[0027] According to the appendix Figure 7 To be continued Figure 10 As shown, the ice removal unit 3 also includes a purge seat 308 fixedly connected to the outer surface of the housing 1. The purge seat 308 has a purge nozzle 309 at its output end. Several purge nozzles 309 are inclined and correspond to the outer surface of the evaporator body 2. The purge seat 308 of the ice removal unit 3 is fixedly installed on the outer surface of the housing 1 and is specifically used to receive and quickly transport the cold flow generated by the vortex tube 306. The purge seat 308 and the vortex tube 306 are connected by a seal to ensure stable and leak-free cold flow delivery, and to ensure that the airflow pressure and velocity meet the standards. The purge seat 308 is equipped with several inclined and directionally arranged purge nozzles 309. The nozzle angles are precisely designed to direct the high-speed cold flow to the surface of each ice tray of the evaporator body 2, providing comprehensive coverage without dead angles. The high-speed cold flow can quickly flush the inner wall of the ice tray, effectively removing residual water film and water droplets generated during the de-icing process, preventing water stains from adhering to the surface of the ice tray, fundamentally reducing the problem of ice sticking to the ice tray during subsequent ice making, and providing a clean and dry preparation environment for the next ice making cycle, ensuring the quality and efficiency of ice making.

[0028] A purge pipe 313 is installed at the input end of the purge base 308. The end of the purge pipe 313 is installed at the cold air end of the vortex tube 306. An electric control valve 310 is installed on the outer wall of the purge pipe 313. The electric control valve 310 can control the start and stop of the purge pipe 313. The purge pipe 313 can quickly transport the cold air in the vortex tube 306 to the purge base 308. While maintaining the high speed of airflow, the airflow temperature is not dissipated, thereby maintaining the high efficiency of purging the ice grid surface of the evaporator body 2. When the de-icing step is performed but the ice grid surface does not need to be purged, the cold air can be discharged to the external environment through the electric control valve 310. When purging is required, it will be transported back to the purge base 308. The integrated ice-making and de-icing unit 4 includes a medium pipe 401 installed on the outer surface of the evaporator body 2. Control valves 402 are installed at the input and output ends of the medium pipe 401 respectively. A water distribution plate 403 is installed inside the shell 1 located on one side of the evaporator body 2. The output end of the water distribution plate 403 corresponds to the outer surface of the evaporator body 2. Through the setting of the integrated ice-making and de-icing unit 4, the integrated control of the ice-making and de-icing processes can be realized. Through linkage with the control unit 5, relying on the data acquisition and analysis function of the control unit 5, it accurately receives and responds to relevant signals, and then controls the external conveying equipment to deliver the corresponding heat medium and cold medium to the medium pipe 401. The heat transfer medium is used to meet the heating requirements during ice removal, while the refrigerant is used to meet the cooling requirements during ice making. The two work together to provide stable medium support for the ice making and ice removal processes. At the same time, the medium pipe 401 installed on the outer wall of the evaporator body 2 is precisely fixed and sealed to effectively ensure the stability of the heat transfer medium and refrigerant supply, avoiding problems such as leakage and uneven flow rate. This enables rapid temperature conduction to the entire evaporator body 2, ensuring rapid cooling during ice making and uniform heating during ice removal, and providing reliable medium delivery and temperature conduction guarantees for the stable operation of the equipment.

[0029] As a key auxiliary component in the ice-making process, the water distribution plate 403 works in conjunction with the evaporator body 2, the external ice-making equipment and the circulating pump. During the normal operation of the evaporator body 2, the circulating pump in the external ice-making equipment is started to draw out the liquid (usually water) required for ice making and deliver it to the water distribution plate 403. The water distribution tray 403 is precisely designed to evenly distribute the delivered liquid. Through its own distribution structure, the liquid is evenly and steadily sprayed onto the surface of each ice grid of the evaporator body 2, ensuring that each ice grid receives a sufficient and uniform liquid supply. Relying on the low-temperature environment generated by the evaporator body 2, the liquid sprayed on the surface of the ice grid can quickly cool down and condense, achieving rapid ice making. This effectively avoids problems such as uneven ice thickness and irregular ice shape caused by uneven liquid distribution, thereby ensuring the stability and consistency of ice preparation and providing qualified ice for subsequent use.

[0030] According to the appendix Figure 3 As shown, a waste heat recovery pipe 311 is installed on the outer wall of the fitting 305. There are multiple waste heat recovery pipes 311, and each end is equipped with a heat conduction valve. During the operation of the ice-making equipment, the heat flow can be precisely controlled by setting up the pipeline and the waste heat recovery pipe 311 on the outer wall, in conjunction with the heat conduction valve. When it is not necessary to use heat flow for de-icing and purging, the heat conduction valve switches its state, directing the generated heat flow into the waste heat recovery pipe 311 and discharging it. Then, in conjunction with the external waste heat absorption equipment, this part of the heat is recovered and utilized, effectively reducing heat loss, avoiding energy waste, and improving the energy utilization efficiency of the entire ice-making system.

[0031] Example 1: This example uses the ice-making and de-icing process as an example. The workflow is as follows: S1, ice making starts. By starting the evaporator body 2 and the integrated ice making and ice removal unit 4, water is continuously sprayed through the water distribution plate 403, and then ice is made through the evaporator body 2. S2, Ice making is completed. By setting the temperature sensing module 503 and the acquisition module 502 in the control unit 5, multiple temperature sensing modules 503 on the outer wall of the evaporator body 2 are used to collect the ice making threshold at multiple points. With the image acquisition and recognition of the acquisition module 502, it is determined whether the ice blocks in the multiple ice compartments of the evaporator body 2 have been prepared. S3, De-icing begins. After receiving the signal, the integrated controller 501 starts the evaporator body 2 and the solenoid valve 307. The heat medium enters through the medium pipe 401 to achieve rapid heating. Simultaneously, compressed air is sent into the vortex tube 306 and separated into hot and cold airflows. The hot airflow is evenly sprayed onto the back of the evaporator body 2 through the spray seat 304 to heat up and de-ice it. When the temperature reaches the bending threshold of the deformation plate 303, the deformation plate 303 bends and pushes the ice block to achieve assisted de-icing. S4, residual water film purging. After de-icing is completed, the acquisition module 502 acquires the surface image of the evaporator body 2 to determine whether all detachment is completed. When detachment is completed, the solenoid valve 307 of the cold flow of the vortex tube 306 is opened, and the outer surface of the evaporator body 2 is purged with cold flow through the purging seat 308 and several purging nozzles 309 to remove the residual water film on its surface. At the same time, the deformation plate 303 is reset by low temperature.

[0032] Example 2: This example uses de-icing as an example. The workflow is as follows: After the ice-making process is started, the control unit 5 starts the evaporator body 2 and the ice-making and de-icing integrated unit 4 in conjunction, so that the two work together to enter the ice-making working state. The ice-making and de-icing integrated unit 4 drives the external circulation pump to deliver the clean water required for ice making to the water distribution plate 403. The water distribution plate 403 uses its own diversion structure to evenly and continuously spray the clean water onto the surface of each ice grid of the evaporator body 2. The evaporator body 2 releases cold energy at the same time to quickly cool down the clean water sprayed on the surface of the ice grid, so that the clean water gradually condenses and forms ice, smoothly promoting the ice-making process and ensuring that the ice is generated evenly and stably. The determination of ice-making completion relies on the coordinated operation of the control unit 5, the temperature sensing module 503, and the data acquisition module 502. The temperature sensing module 503 is installed on the back of the evaporator body 2 to achieve multi-point synchronous data acquisition and accurately capture the temperature changes in different ice grid areas. By comparing with the preset ice-making temperature threshold, the degree of ice condensation is determined. Meanwhile, the acquisition module 502 acquires images in real time, capturing features such as the shape and thickness of the ice in the ice trays. Combined with image recognition technology, it helps to determine whether the ice has reached the preset forming standard. The two data complement each other and verify each other, avoiding the error of a single judgment method. This ensures accurate identification of whether the ice in all ice trays of the evaporator body 2 has been prepared, providing a reliable basis for switching to the de-icing process and ensuring the quality of ice making and the smooth flow of the process. After receiving the ice-making completion and de-icing start signals, the integrated controller 501 immediately starts the evaporator body 2 into de-icing mode and opens the solenoid valve 307 to deliver heat medium to the evaporator body 2 through the medium pipe 401, achieving rapid heating and providing basic heat for de-icing; at the same time, external compressed air is sent into the vortex tube 306, which separates it into hot and cold airflows. The hot airflow is delivered to the spray seat 304 and sprayed evenly onto the back of the evaporator body 2 through the spray seat 304, further increasing the overall temperature and accelerating the separation of ice from the ice grid. When the temperature reaches the preset bending threshold of the deformation sheet 303, the deformation sheet 303 undergoes elastic deformation and bends towards the ice body. Through physical pushing action, it assists the ice block to detach, effectively improving the ice removal efficiency and integrity, and ensuring a smooth and efficient ice removal process. After the de-icing process is completed, residual water film purging and de-icing effect confirmation are required: start the acquisition module 502 to acquire images of the surface of the evaporator body 2, and accurately determine whether the ice has completely detached and has no residual adhesion through image analysis. After confirming that the de-icing is completed, the integrated controller 501 controls the opening of the electronically controlled valve 310 corresponding to the cold flow of the vortex tube 306, and delivers the cold flow gas to the purging seat 308, and then sprays the cold flow evenly onto the outer surface of the evaporator body 2 through multiple purging nozzles 309. The high-speed cold flow can not only quickly remove the residual water film on the surface of the ice tray and the evaporator body 2, avoiding water stains from affecting subsequent ice making, but also the low-temperature cold flow can cause the deformed sheet 303 that has been bent by heat to cool down quickly and return to its original shape, thus restoring it to its original state and making full preparations for the next round of ice making and de-icing processes, ensuring the continuous and stable operation of the equipment.
