DETAILED DESCRIPTION

[0028] The following will describe the present invention in detail in conjunction with the specific implementations shown in the accompanying drawings. However, these implementations do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these implementations are all within the scope of protection of the present invention.

[0029] Reference Figure 1 The refrigeration device 1 of the present invention refers to a mechanical system or device for reducing and controlling the temperature of an object or space. Based on the characteristic that the refrigeration device 1 can reduce the temperature of a space or an object, the refrigeration device 1 is widely used in homes, businesses and other places.

[0030] In one embodiment of the present invention, the refrigeration device 1 may be a refrigerator. A refrigerator is one of the most common refrigeration devices 1 in a household, and is used to store food, prevent food from spoiling, and extend its shelf life.

[0031] Reference Figure 1 In this embodiment, the refrigeration device 1 includes a box body 2. The box body 2 includes a box shell 11 and an inner liner 12. The box shell 11 is used to protect the internal components and provide a stable structure. The box shell 11 can be made of steel or other metals. The inner liner 12 is arranged inside the box shell 11. The inner liner 12 is usually made of plastic. The box shell 11 and the inner liner 12 are usually manufactured by large-scale injection molding or molding machines.

[0032] The box body 2 also includes a box body 2 insulation layer disposed between the box shell 11 and the liner 12. The box body 2 insulation layer is generally formed by foaming the box body 2. Foaming of the box body 2 of the refrigeration device 1 is a key production step, which is essential for ensuring that the refrigeration device 1 has good insulation performance and energy efficiency.

[0033] Before foaming, it is necessary to preliminarily assemble the box shell 11 and the inner liner 12 of the refrigeration device 1 of the box body 2, so that there is a certain foaming space between the box shell 11 and the inner liner 12 for filling the foaming material. The foaming material is usually liquid polyurethane or other similar compounds. Before injection, these chemicals are in liquid form and can be accurately injected into the gap of the shell of the refrigeration device 1 through a special nozzle and injection equipment. Once injected into the foaming space, the foaming material will quickly start a chemical reaction, produce gas and expand. This expansion action fills the foaming space and forms a continuous insulation layer of the box body 2. As the chemical reaction proceeds, the foaming material begins to solidify, becomes hard and has good structural strength, providing the necessary mechanical support for the refrigeration device 1.

[0034] The good thermal insulation performance of the insulation layer of the box body 2 can significantly reduce the energy consumption of the refrigeration equipment 1. After hardening, the insulation layer of the box body 2 increases the strength of the entire refrigeration equipment 1 structure, making the refrigeration equipment 1 more sturdy and durable. The insulation layer of the box body 2 also helps to reduce noise during operation and provide a quieter use environment.

[0035] The refrigeration device 1 also includes components such as a compressor, a condenser, an expansion valve and an evaporator, which work together through a refrigeration cycle process.

[0036] The refrigeration cycle generally includes a compression process, a condensation process, an expansion process, and an evaporation process. The compression process is that the compressor compresses the refrigerant gas, making it hot and increasing the pressure. The condensation process is that the high-pressure hot gas releases heat in the condenser, and the refrigerant cools and condenses into a liquid. The expansion process is that the liquid refrigerant passes through the expansion valve (throttle valve), its pressure is reduced, and enters the evaporator. The evaporation process is that in the evaporator, the low-pressure refrigerant absorbs heat from the surrounding environment and evaporates into a gas. This process causes the temperature of the surrounding environment to drop. The cycle of compression process, condensation process, expansion process, and evaporation process is repeated continuously, thereby achieving a continuous cooling effect of the refrigeration equipment 1.

[0037] The refrigeration device 1 also includes a machine room. The machine room is usually arranged at the bottom of the box body 2. The compressor, condenser, and expansion valve are usually arranged in the machine room.

[0038] The evaporator of the refrigeration device 1 can be a plate evaporator, a tubular evaporator, a fin evaporator (fin evaporator), etc. The plate evaporator is usually composed of a plurality of flat metal plates, and the refrigerant flows between the plates. The tubular evaporator is composed of a series of connected pipes, and the refrigerant flows in the pipes. The fin evaporator includes a refrigerant pipe and a metal sheet installed on the periphery of the refrigerant pipe. These metal sheets are used to increase the heat exchange area and improve the heat transfer efficiency. The evaporator of the refrigeration device 1 can be installed at different positions of the refrigeration device 1, such as on the back or side wall of the refrigeration device 1.

[0039] Generally, after the box body 2 is foamed, the compressor, condenser, evaporator and circuit are installed to ensure the performance and safety of the refrigeration device 1.

[0040] Reference Figure 1 and Figure 2 A storage chamber may be formed inside the inner tank 12. The storage chamber may be used to store food. The refrigeration device 1 includes a first storage chamber 3 and a second storage chamber 4 formed in the box body 2.

[0041] In this patent, the front-to-back direction refers to the depth direction of the refrigeration device 1, the left-right direction refers to the width direction of the refrigeration device 1, and the up-down direction refers to the height direction of the refrigeration device 1. Among them, the opening direction of the compartment of the storage room is the front, and the direction opposite to the opening direction of the compartment of the storage room is the back.

[0042] The storage room can be a cold room. The cold room is used to store most foods that need to be refrigerated, such as dairy products, cooked food, fruits and vegetables, etc., and its temperature range is usually set between 3°C and 5°C.

[0043] The storage room can be a freezer. The freezer is used to store foods that need to be frozen, such as meat, seafood, frozen foods, etc., to keep them fresh for a long time, and its temperature range is usually set below -18°C.

[0044] The storage room can also be a variable temperature room. The variable temperature room is a multifunctional storage space designed to provide adjustable temperature settings to meet the preservation requirements of different foods. The variable temperature room can adjust the temperature according to the needs of the user and can be used as a refrigerator, a low-temperature fresh-keeping room or a freezer. When additional refrigeration space is needed or more freezing space is temporarily needed, the variable temperature room of the refrigeration device 1 provides extremely high flexibility, allowing users to adjust the appropriate temperature according to different food types and preservation requirements, thereby maintaining the best freshness and quality of the food.

[0045] The storage room may also be other types of compartments besides a refrigerated room, a freezer room, or a temperature-changing room.

[0046] The refrigeration device 1 further comprises an ice-making chamber 5 arranged in the first storage chamber 3 and an ice-making machine 6 arranged in the ice-making chamber 5. An ice storage box may be arranged below the ice-making machine 6.

[0047] The refrigeration device 1 may include a partition 17 disposed in the first storage chamber 3. The partition 17 may be arranged with the wall of the first storage chamber 3 to form an ice-making chamber 5. Preferably, the partition 17 may be arranged horizontally in the first storage chamber 3, and the partition 17 and the top wall of the first storage chamber 3, the left and right side walls of the first storage chamber 3, the rear wall of the first storage chamber 3 and the rear wall of the ice-making chamber 5 together enclose a relatively independent space, which is the ice-making chamber 5. The ice-making chamber 5 is located at the top of the first storage chamber 3. In other embodiments, the partition 17 may also be arranged longitudinally in the first storage chamber 3, and the ice-making chamber 5 may also be formed by the partition 17 and the wall of the first storage chamber 3 in other ways, and the ice-making chamber 5 may also be located in the middle or bottom of the first storage chamber 3.

[0048] Reference Figures 1 to 3 In this embodiment, the refrigeration device 1 further includes an ice-making evaporation chamber 7 disposed in the second storage chamber 4, an ice-making evaporator 8 disposed in the ice-making evaporation chamber 7, an ice-making air supply path 9 and an ice-making return air path 10 connecting the ice-making evaporation chamber 7 and the ice-making chamber 5. The ice-making evaporation chamber 7 is only used to supply cold air to the ice-making chamber 5. The cold air in the ice-making evaporation chamber 7 enters the ice-making chamber 5 through the ice-making air supply path 9, and the air in the ice-making chamber 5 enters the ice-making evaporation chamber 7 through the ice-making return air path 10. The ice-making evaporation chamber 7 is completely closed relative to the second storage chamber 4, that is, the air between the ice-making evaporation chamber 7 and the second storage chamber 4 is completely non-circulated.

[0049] By providing an independent ice-making chamber 5 in the first storage chamber 3 of the refrigeration device 1 and configuring an ice-making evaporation chamber 7 and an ice-making evaporator 8 in the second storage chamber 4 for supplying cold to the ice-making chamber 5, this design has many significant advantages.

[0050] The ice-making evaporator 8 that is specifically used to supply cold air to the ice-making chamber 5 can be used to adjust the temperature of the ice-making chamber 5 without being affected by the temperature changes of other parts of the refrigeration device 1, allowing for more precise control of the internal environment of the ice-making chamber 5, which helps maintain a more stable low temperature in the ice-making chamber 5, thereby improving the efficiency and quality of ice making. The ice-making chamber 5 is independent of the first storage chamber 3, and the cold air in the ice-making chamber 5 will not be lost each time the first storage chamber 3 is opened, which helps save energy and maintain a low temperature environment in the ice-making chamber 5. In addition, the independent ice-making chamber 5 and the ice-making evaporator chamber 7 that is specifically used to supply cold air to the ice-making chamber 5 help prevent the food odor of the first storage chamber 3 and the second storage chamber 4 from entering the ice-making area, because the odor tends to spread through the air inside the refrigeration device 1. By isolating the ice-making chamber 5, the chance of ice cubes coming into contact with the food odor can be reduced, ensuring that the ice cubes produced are clean and odorless.

[0051] Since the internal space of the ice-making room 5 is limited, if the ice-making evaporation room 7 and the ice-making evaporator 8 are arranged inside the ice-making room 5, more internal space of the ice-making room 5 will be occupied, making it difficult to arrange the ice-making machine 6 in the ice-making room 5. If the ice-making room 5 adopts a double ice-making machine 6 solution or a larger ice-making machine 6 solution, the space of the ice-making room 5 often cannot meet the size requirements. The ice-making evaporation room 7 and the ice-making evaporator 8 are placed in other storage rooms, and then the ice-making evaporation room 7 is used to exclusively supply cold air to the ice-making room 5 through an independent ice-making air supply duct 9 and an ice-making return duct 10. This can achieve the effect of clean ice cubes without odor, while avoiding the ice-making evaporation room 7 and the ice-making evaporator 8 occupying the internal space of the ice-making room 5, and facilitating the arrangement of the ice-making machine 6.

[0052] Reference Figure 1 and Figure 2 In one embodiment of the utility model, the inner tank 12 includes a first inner tank 121 forming the first storage chamber 3 and a second inner tank 122 forming the second storage chamber 4. The second inner tank 122 is provided with an air duct 13 for supplying cold to the second storage chamber 4. The refrigeration device 1 also includes a storage evaporator provided outside the second storage chamber 4 and for supplying cold to the air duct 13.

[0053] Reference Figures 2 to 6 The refrigeration device 1 includes a water receiving tray 14 disposed in the ice making evaporation chamber 7. The water receiving tray 14 is disposed below the ice making evaporator 8. The water receiving tray 14 is provided with a drainage portion 141. The wall of the air duct 13 is formed with an air duct drainage port 131, and the drainage portion 141 extends into the air duct drainage port 131.

[0054] By extending the drainage portion 141 into the air duct 13 to drain water, the space in the air duct 13 can be effectively utilized, reducing the space occupied in the second storage chamber 4. By providing cooling to the air duct 13 through the storage evaporator arranged outside the second storage chamber 4, the drainage effect of the water receiving tray 14 can be ensured, and it is avoided that the storage evaporator is arranged in the air duct 13, which may cause the drainage portion 141 to be easily frozen.

[0055] Reference Figure 1 , Figure 2 , Figures 5 to 8 In one embodiment of the utility model, the refrigeration device 1 includes an air duct cover plate 15 disposed in the second storage chamber 4, and the air duct cover plate 15 and the wall of the inner tank 12 surround the air duct 13. The wall of the inner tank 12 is formed with an inner tank drain port 1221. The refrigeration device 1 also includes a drainage channel 16 connecting the air duct drain port 131 and the inner tank drain port 1221.

[0056] The water outlet end of the drain pipe 19 can be connected to the evaporation dish in the machine room to discharge the water in the water receiving tray 14 into the evaporation dish, and the water in the evaporation dish is evaporated by the heat generated by the compressor in the machine room. The drain member 18 can be pre-buried in the wall of the inner tank 12 through the foaming of the box body 2. The drain member 18 is arranged in the heat preservation space to avoid occupying the internal space of the air duct 13. Through the cooperation of the drainage channel 16, the drain member 18 and the drain pipe 19, the water in the water receiving tray 14 can be effectively discharged, and the structure is simple and compact.

A first sealing member is provided between the first protruding edge 142 and the wall of the air duct 13. By providing the first protruding edge 142 and the first sealing member, the cooperation effect between the drain portion 141 and the wall of the air duct 13 can be ensured, and water or cold air can be prevented from leaking from the gap between the drain portion 141 and the wall of the air duct 13.

[0058] Reference Figure 5 , Figure 7 and Figure 8 In one embodiment of the utility model, the drainage channel 16 is provided with a second protruding edge 161 covering the edge of the inner tank drain port 1221, and a second sealing member is provided between the second protruding edge 161 and the wall of the inner tank 12.

[0059] In one embodiment of the utility model, a heating element may be provided at the drainage portion 141, the air duct drainage port 131, the drainage channel 16, and the inner tank drainage port 1221. The heating element may be a heating wire, etc. By providing a heating element, it is possible to prevent the drainage from freezing and avoid ice blockage during drainage.

[0060] In one embodiment of the present invention, the bottom wall of the water receiving tray 14 is inclined downward toward the water outlet side of the drainage portion 141. The bottom walls of the water receiving tray 14 on both sides of the drainage portion 141 are inclined downward toward the drainage portion 141.

[0061] Reference Figures 1 to 8 Preferably, the air duct cover plate 15 is arranged at the rear side of the second storage chamber 4, and the air duct cover plate 15 is formed to allow the rear wall of the storage chamber.

The fan 23 can be arranged on the rear side of the ice-making evaporator 8. The fan 23 can be a centrifugal fan 23. In other embodiments, the fan 23 can also be a perfusion fan 23. The fan 23 can be opposite to the air outlet 71. When the fan 23 is started, the cold air in the ice-making evaporation chamber 7 can be accelerated to enter the ice-making chamber 5 through the ice-making air supply path 9, and the air in the ice-making chamber 5 can enter the ice-making evaporation chamber 7 through the ice-making return air path 10, thereby improving the ice-making efficiency.

[0069] Reference Figure 2 and Figure 3 In one embodiment of the utility model, the refrigeration device 1 further includes a heat preservation layer disposed between the ice-making evaporation chamber 7 and the second storage chamber 4. The heat preservation layer may be a heat preservation board formed by heat preservation material. The heat preservation board may be disposed in the ice-making evaporation chamber 7 and located between the water receiving tray 14 and the housing 22. The heat preservation layer can prevent the cold air in the ice-making evaporation chamber 7 from leaking, and can also prevent condensation from forming on the surface of the housing 22 due to the temperature difference between the ice-making evaporation chamber 7 and the second storage chamber 4.

[0070] Reference Figure 2 and Figure 3 In one embodiment of the utility model, the first storage chamber 3 is a freezer. The second storage chamber 4 is a variable temperature chamber or a freezer or a refrigeration chamber. Preferably, the second storage chamber 4 is a variable temperature chamber. The ice making chamber 5 is arranged on the top of the first storage chamber 3, and the ice making evaporation chamber 7 is arranged on the top of the second storage chamber 4. The ice making chamber 5 and the ice making evaporation chamber 7 are both arranged on the top, which can make it easier to cooperate with the ice making evaporation chamber 7 and the ice making chamber 5, reduce the length of the wind path, and reduce the air volume loss.

[0071] Reference Figure 2 In one embodiment of the utility model, the refrigeration device 1 includes a storage evaporation chamber 1211 arranged in the first inner tank 121, the storage evaporator is arranged in the storage evaporation chamber 1211, the storage evaporation chamber 1211 is located at the rear side of the first storage chamber 3, and the refrigeration device 1 also includes a storage air supply path connecting the storage evaporation chamber 1211 and the air duct 13, and the cold air in the storage evaporation chamber 1211 enters the air duct 13 through the storage air supply path. The storage evaporator is a freezing evaporator. Preferably, the storage evaporation chamber 1211 supplies cold air to the first storage chamber 3 by air cooling, and the air duct 13 supplies cold air to the second storage chamber 4 by air cooling. In other embodiments, the storage evaporation chamber 1211 can also supply cold air to the first storage chamber 3 by direct cooling. The air duct 13 can also supply cold air to the second storage chamber 4 by direct cooling.

[0072] In one embodiment of the utility model, the refrigeration equipment 1 may refer to a display cabinet. Display cabinets are widely used in commercial environments, mainly for displaying and preserving food, such as beverages, cooked food, cakes and dairy products. This type of equipment not only keeps food at a suitable temperature, but also optimizes the display of goods to attract customers to buy. Display cabinets have various designs and structures, and can be roughly divided into several types according to different usage requirements and occasions, including vertical, desktop, hanging and built-in types. Display cabinet components can keep food at a safe and suitable temperature, extend the shelf life of food, and prevent food from spoiling. Its transparent design makes the food clear at a glance, allowing customers to easily view and select the goods they want, improving shopping efficiency.

[0073] In one embodiment of the utility model, the refrigeration device 1 may refer to a freezer. Freezers are widely used in home, commercial and industrial environments. The design of freezers usually focuses on large capacity, convenient access and maintaining a consistent low temperature environment. They are very suitable for storing large amounts of frozen food, especially perishable items such as meat, seafood, frozen food and frozen vegetables. For users who need to store large amounts of frozen food, such as large families, restaurant owners or retailers, freezers provide ample storage space. Compared with refrigerators that are opened frequently, freezers are opened less frequently, which helps to maintain a stable internal temperature and reduce energy consumption.

[0074] In summary, the refrigeration device 1 of the present invention can solve the problem that the ice cubes produced by the ice maker 6 are easily contaminated by the odor and bacteria in the storage room, resulting in the prepared ice cubes being unclean.

[0075] By adopting the technical solution of the utility model, an independent ice-making chamber 5 is provided in the storage room of the refrigeration equipment 1, and an ice-making evaporation chamber 7 and an ice-making evaporator 8 are configured to specifically supply cold to the ice-making chamber 5, so that the ice cubes made by the ice-making machine 6 in the ice-making chamber 5 can be prevented from being contaminated by the odor and bacteria in the storage room, thereby ensuring the cleanliness of the ice-making chamber 5, improving the quality of ice-making, improving the efficiency of ice-making and saving energy. The ice-making evaporation chamber 7 and the ice-making evaporator 8 are placed in other storage rooms, and then the ice-making evaporation chamber 7 is used to specifically supply cold to the ice-making chamber 5 through the independent ice-making air supply air path 9 and the ice-making return air path 10, so that the ice cubes can be clean and not odor-stained, while avoiding the ice-making evaporation chamber 7 and the ice-making evaporator 8 from occupying the internal space of the ice-making chamber 5, and facilitating the installation of the ice-making machine 6. By extending the drainage portion 141 into the air duct 13 to drain water, the space in the air duct 13 can be effectively utilized, reducing the space occupied in the second storage chamber 4. By providing cooling to the air duct 13 through the storage evaporator arranged outside the second storage chamber 4, the drainage effect of the water receiving tray 14 can be ensured, and it is avoided that the storage evaporator is arranged in the air duct 13, which may cause the drainage portion 141 to be easily frozen.
