Description

Technical Field

[0001] This utility model belongs to the field of ice maker technology, and in particular relates to a dual heat dissipation ice maker. Background Technology

[0002] An ice maker is a refrigeration machine that uses a refrigeration system to cool water through an evaporator to produce ice. It employs a refrigeration system with water as the carrier, and produces ice by passing the water through a device when powered on. Depending on the evaporator's principle and production method, the shape of the ice produced varies. Ice makers are generally classified by ice shape, such as granular ice machines, flake ice machines, plate ice machines, tube ice machines, and shell ice machines.

[0003] Currently, ice makers generally use air-cooled components for heat dissipation. However, in regions with significant temperature differences between winter and summer, to meet the heat dissipation requirements of equipment in high-temperature environments, the heat dissipation performance is usually enhanced by increasing the heat dissipation area of ​​the air-cooled components. While this approach can alleviate the heat dissipation pressure under high-temperature conditions, it also brings two problems: First, the enlarged heat dissipation module occupies more space, which is not conducive to the compact design of the equipment structure; second, in low-temperature environments, excessive heat dissipation capacity can lead to excessively low condensing pressure in the refrigeration system, resulting in insufficient refrigerant circulation, causing a decrease in ice-making efficiency or even failure to start ice making normally. Therefore, traditional heat dissipation designs cannot simultaneously meet the performance requirements under different high and low temperature conditions, restricting the stable operation and energy efficiency optimization of ice makers under all climate conditions. Utility Model Content

[0004] The purpose of this invention is to solve the aforementioned technical problems in the existing technology by providing a dual-heat dissipation ice maker. By integrating both air-cooled and water-cooled heat dissipation components, which work collaboratively according to changes in ambient temperature, this effectively solves the technical challenge of traditional single-air-cooled ice makers struggling to handle both high and low temperature conditions in regions with large temperature differences between winter and summer. In high-temperature environments, the dual heat dissipation modes operate simultaneously, significantly enhancing the system's heat dissipation capacity and ensuring stable condensing pressure within the efficient ice-making range, thus guaranteeing ice-making efficiency and output. In low-temperature environments, only the air-cooled components provide moderate heat dissipation, avoiding problems such as excessively low system condensing pressure and poor refrigerant circulation caused by excessive heat dissipation. This ensures normal start-up and stable ice-making performance at low temperatures. It overcomes the contradiction between the space occupation and decreased low-temperature performance resulting from simply increasing the air-cooling heat dissipation area, and achieves efficient and reliable operation of the ice maker under all climate conditions.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A dual-heat dissipation ice maker includes an ice tray assembly and a compressor, with the ice tray assembly connected to the compressor; characterized in that it further includes an air-cooled assembly and a water-cooled assembly, with the air-cooled assembly connected to both the compressor and the water-cooled assembly, and the water-cooled assembly connected to the ice tray assembly, wherein the compressor compresses the refrigerant, which is then cooled by the air-cooled assembly and the water-cooled assembly before flowing into the ice tray assembly.

[0007] By integrating both air-cooled and water-cooled heat dissipation components, which work in tandem according to changes in ambient temperature, this system effectively solves the technical challenge of traditional single-air-cooled ice makers struggling to handle both high and low temperature conditions in regions with significant temperature differences between winter and summer. In high-temperature environments, the dual heat dissipation modes operate simultaneously, significantly enhancing the system's heat dissipation capacity and ensuring stable condensing pressure within the efficient ice-making range, thus guaranteeing ice-making efficiency and output. In low-temperature environments, only the air-cooled components provide moderate heat dissipation, avoiding problems such as excessively low system condensing pressure and poor refrigerant circulation caused by excessive heat dissipation. This ensures normal startup and stable ice-making performance at low temperatures. It overcomes the contradiction between the space occupation and low-temperature performance caused by simply increasing the air-cooling heat dissipation area, achieving efficient and reliable operation of the ice maker under all climate conditions.

[0008] Furthermore, the air-cooled assembly includes a finned condenser, which has a first liquid inlet and a first liquid outlet. The first liquid inlet is connected to the compressor through a first flow pipe, and the first liquid outlet is connected to the water-cooled assembly through the first flow pipe.

[0009] Furthermore, the water-cooling assembly includes a water pressure valve and a water-cooling pipe. The water-cooling pipe has an inlet and an outlet. The inlet is connected to the water pressure valve through an inlet pipe, and the outlet is used to discharge the cooling water in the water-cooling pipe.

[0010] Furthermore, the water-cooling pipe is provided with a second liquid inlet and a second liquid outlet. The second liquid inlet is connected to the water-cooling component, and the second liquid outlet is connected to the ice tray component through a second flow pipe.

[0011] Furthermore, the second circulation pipeline is equipped with a first filter and a first storage tank.

[0012] Furthermore, the second flow pipeline is connected to an expansion valve, and the ice tray assembly is provided with a flow port, with the expansion valve connected to the flow port.

[0013] Furthermore, the water-cooling pipe has a double-layer structure and is spiral-shaped, with refrigerant and cooling water flowing in the inner and outer layers of the water-cooling pipe, respectively.

[0014] Furthermore, the ice tray assembly is equipped with a reflux port, which is connected to the compressor via a reflux pipeline. The reflux pipeline is equipped with a second filter and a second liquid storage tank.

[0015] Furthermore, it also includes a de-icing solenoid valve, which is connected to the compressor and the ice tray assembly via connecting pipes.

[0016] Furthermore, the ice tray assembly includes an ice tray, a water pump, and a water tank, with the water pump installed in the water tank and connected to the ice tray.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] 1. This utility model effectively solves the technical problem of traditional single-air-cooled ice makers struggling to handle both high and low temperature conditions in regions with large temperature differences between winter and summer by integrating two sets of heat dissipation components: air cooling and water cooling. These components work in tandem according to changes in ambient temperature. In high-temperature environments, the dual heat dissipation modes operate simultaneously, significantly enhancing the system's heat dissipation capacity and ensuring stable condensing pressure within the efficient ice-making range, thus guaranteeing ice-making efficiency and output. In low-temperature environments, only the air cooling components provide moderate heat dissipation, avoiding problems such as excessively low system condensing pressure and poor refrigerant circulation caused by excessive heat dissipation. This ensures the ice maker's normal start-up and stable ice-making performance at low temperatures. It overcomes the contradiction between the space occupation and low-temperature performance caused by simply increasing the air cooling area, while achieving efficient and reliable operation of the ice maker under all climate conditions.

[0019] 2. In this utility model, the de-icing solenoid valve is connected to the compressor and the ice tray assembly through connecting pipes. At the end of the ice-making cycle, by opening the de-icing solenoid valve, some high-temperature and high-pressure refrigerant is directly introduced into the ice tray assembly, which briefly increases the temperature of the ice tray and melts the contact surface between the ice and the ice tray, thereby achieving automatic de-icing and improving the automation level and ice-removing efficiency of the equipment.

Detailed Implementation

[0027] like Figures 1 to 5 As shown, this utility model discloses a dual-heat dissipation ice maker, including an ice tray assembly, a compressor 1, an air-cooled assembly, a water-cooled assembly, and an ice-removing solenoid valve 22. One end of the compressor 1 is connected to the air-cooled assembly, and the other end of the air-cooled assembly is connected to the water-cooled assembly. The water-cooled assembly is connected to the ice tray assembly. The two ends of the ice-removing solenoid valve 22 are connected to the compressor 1 and the ice tray assembly respectively through connecting pipes 23. During normal ice making, the compressor 1 compresses the refrigerant. The high-temperature and high-pressure refrigerant passes through the air-cooled assembly, where heat exchange occurs between the air-cooled assembly and the refrigerant, thus dissipating heat from the refrigerant. Then, the refrigerant passes through the water-cooled assembly again, where heat is dissipated once more, ultimately forming a low-temperature and low-pressure refrigerant that flows into the ice tray assembly.

[0028] It should be noted that when this invention is used in a high-temperature environment, both the air-cooled and water-cooled components operate in a dual-heat dissipation mode, significantly enhancing the system's heat dissipation capacity and ensuring that the condensing pressure remains stable within the high-efficiency ice-making range, thus guaranteeing ice-making efficiency and output. When used in a low-temperature environment, the water-cooled component is turned off, relying solely on the air-cooled component for moderate heat dissipation, avoiding problems such as excessively low system condensing pressure and poor refrigerant circulation caused by excessive heat dissipation. At the same time, when the ice-making cycle ends, by opening the de-icing solenoid valve 22, some high-temperature and high-pressure refrigerant is directly introduced into the ice tray assembly, briefly increasing the temperature of the ice tray 24, causing the ice to melt at the contact surface with the ice tray 24, thereby achieving automatic de-icing and improving the automation level and ice-removal efficiency of the equipment.

[0029] By integrating both air-cooled and water-cooled heat dissipation components, and having them work in tandem according to changes in ambient temperature, this system effectively solves the technical challenge of traditional single-air-cooled ice makers struggling to handle both high and low temperature conditions in regions with large temperature differences between winter and summer. This ensures the ice maker's normal start-up and stable ice-making performance at low temperatures. It overcomes the contradiction between the increased space requirements and decreased low-temperature performance resulting from simply increasing the air-cooling heat dissipation area, while achieving efficient and reliable operation of the ice maker under all climate conditions.

[0030] The air-cooled assembly includes a finned condenser 2, which has a first liquid inlet 3 and a first liquid outlet 4. The first liquid inlet 3 is connected to the compressor 1 through a first flow pipe 5, and the first liquid outlet 4 is connected to the water-cooled pipe 7 through the first flow pipe 5. The high-temperature refrigerant from the compressor 1 enters the finned condenser 2 through the first flow pipe 5 and the first liquid inlet 3. When flowing through the finned condenser 2, it exchanges heat with the air, undergoes preliminary condensation and heat dissipation through the finned condenser 2, and finally enters the water-cooled pipe 7 through the first liquid outlet 4 and the first flow pipe 5.

[0031] The water-cooling assembly includes a water pressure valve 6, a water-cooling pipe 7, and an expansion valve 16. The water-cooling pipe 7 has an inlet 8, an outlet 9, a second liquid inlet 12, and a second liquid outlet 11. The inlet 8 is connected to the water pressure valve 6 through an inlet pipe 10. The outlet 9 is connected to the outside through an outlet pipe 28, through which the cooling water in the water-cooling pipe 7 is discharged. The second liquid inlet 12 is connected to the first liquid outlet 4 of the finned condenser 2 through a first flow pipe 5. The second liquid outlet 11 is connected to the ice tray assembly through a second flow pipe 13. The expansion valve 16 is installed at the end of the second flow pipe 13. The ice tray assembly has a flow port 17, and the expansion valve 16 is connected to the flow port 17.

[0032] The flow and pressure of cooling water are stably controlled by water pressure valve 6, and the heat of the refrigerant is removed by water cooling pipe 7. It is specially designed for high-temperature environments and serves as a powerful supplement to air cooling. It greatly improves the heat dissipation limit of the system under extreme conditions. The high-pressure refrigerant is throttled and depressurized by expansion valve 16, which transforms it into a low-temperature and low-pressure refrigerant, creating the necessary conditions for the refrigerant to absorb heat and make ice in the ice plate assembly.

[0033] The water-cooled pipe 7 has a double-layer structure and is spiral in shape. The refrigerant and cooling water flow in the inner and outer layers of the water-cooled pipe 7, respectively. The double-layer structure design achieves the isolation and close contact between the refrigerant and cooling water, realizes the heat exchange between the refrigerant and cooling water, and improves the heat exchange efficiency. The spiral design increases the heat exchange area and ensures the heat exchange effect.

[0034] The second flow pipeline 13 is also equipped with a first filter 14 and a first liquid receiver 15. The first filter 14 can effectively filter impurities and moisture that may exist in the refrigerant, preventing ice blockage or dirt blockage in the system pipeline, especially the expansion valve 16. The first liquid receiver 15 is used to store the high-pressure refrigerant after condensation, playing a role in buffering and stabilizing the liquid supply, ensuring that the refrigerant flowing to the expansion valve 16 is continuous and stable, and improving the reliability of the system.

[0035] The ice tray assembly is equipped with a return port 18, which is connected to the compressor 1 via a return pipe 19. The return pipe 19 is equipped with a second filter 20 and a second liquid receiver 21. The design of the return port 18 ensures that the refrigerant after absorbing heat in the ice tray 24 can return smoothly to the compressor 1 to complete the entire refrigeration cycle. The second filter 20 and the second liquid receiver 21 further ensure the cleanliness of the returned refrigerant and prevent liquid refrigerant from directly entering the compressor 1, effectively protecting the compressor 1 from liquid slugging damage and extending the life of core components.

[0036] The ice tray assembly includes an ice tray 24, a water pump 25, and a water tank 26. The water pump 25 is installed in the water tank 26 and is connected to the ice tray 24. The water pump 25 continuously pumps water from the water tank 26 into the distributor of the ice tray 24, so that it flows evenly over the low-temperature surface of the ice tray 24 and gradually freezes into ice, ensuring the continuous ice-making process and the quality of the ice blocks.

[0037] Furthermore, a water level float 27 can be installed in the water tank 26 to detect the water level in the water tank 26, making it convenient to add water to the water tank 26.

[0038] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
