Description

Technical Field

[0001] This application relates to the field of refrigeration electrical technology, specifically a refrigeration device. Background Technology

[0002] Refrigerators, freezers, wine cabinets, beverage coolers, and other refrigeration equipment are containers that use the phase change of refrigerants to create a low-temperature environment for storing food and other items. They are indispensable household appliances. As people's living standards improve, the requirements for refrigeration equipment are also increasing.

[0003] In refrigeration equipment such as refrigerators, the unit typically includes a cabinet, an evaporator, and an air duct assembly. The cabinet serves as the outer shell of the refrigeration equipment. Inside the cabinet is a refrigeration compartment for storing items. The evaporator blows cold air into the refrigeration compartment through the air duct assembly, thereby cooling the compartment. Evaporators are prone to frost buildup during cooling, therefore, they require active defrosting to avoid affecting their cooling efficiency.

[0004] In existing refrigeration equipment, the evaporator is heated during defrosting, which generates hot air in the evaporation chamber. Since the evaporator remains connected to the refrigeration chamber during defrosting, the hot air in the evaporation chamber can easily blow into the refrigeration chamber, causing the temperature of the refrigeration chamber to rise and thus affecting the refrigeration effect of the refrigeration chamber. Utility Model Content

[0005] The purpose of this application is to provide a refrigeration device to optimize the structure of refrigeration devices in related technologies, thereby addressing the problem that the temperature of the refrigeration chamber rises during evaporator defrosting, thus affecting the refrigeration effect of the refrigeration device.

[0006] The purpose of this application is not limited to the purposes mentioned above, and those skilled in the art will clearly understand other purposes not mentioned from the following description.

[0007] To solve the above-mentioned technical problems, this application provides a refrigeration device, comprising: a housing configured as the outer shell of the refrigeration device; a refrigeration chamber provided inside the housing; an evaporation chamber formed inside the housing; an evaporator disposed inside the evaporation chamber; an air supply duct disposed inside the housing; an air inlet and an air outlet respectively provided on the side wall of the air supply duct; the air supply duct communicating with the evaporation chamber through the air inlet and communicating with the refrigeration chamber through the air outlet; a first fan disposed inside the air supply duct and at the air inlet; the first fan is configured to: draw air from the evaporation chamber through the air inlet and deliver it to the refrigeration chamber through the air supply duct and the air outlet; and a second fan disposed at the air inlet; the second fan is configured to: draw air from the air supply duct and deliver it to the evaporation chamber through the air inlet.

[0008] One of the above technical solutions has the following advantages or beneficial effects: When the refrigeration equipment is in cooling mode, a first fan draws cold air from the evaporator chamber and delivers it to the refrigeration room through the air inlet, air duct, and air outlet, thereby achieving the cooling effect of the refrigeration equipment. When the refrigeration equipment is in defrosting mode, a second fan draws air from the air duct and reverses its flow through the air inlet to the evaporator chamber, thus preventing hot air generated during evaporator defrosting from entering the refrigeration room through the air duct. This reduces temperature changes in the refrigeration room during defrosting, preventing any impact on the refrigeration effect. Furthermore, because the temperature rise in the refrigeration room is not significant, after defrosting and returning to cooling mode, the refrigeration room can quickly recover to the required low-temperature environment, saving time and costs associated with the refrigeration room's recovery.

[0009] In some embodiments, the refrigeration equipment further includes a mounting bracket fixed at the air inlet, and the second fan is rotatably mounted on the mounting bracket.

[0010] One of the above technical solutions has the following advantages or beneficial effects: This application utilizes an installation bracket to enable the second fan to rotate stably at the air inlet, thereby improving the stability of the second fan's rotation at the air inlet.

[0011] In some embodiments, the mounting bracket is disposed inside the evaporation chamber, and the end of the mounting bracket is connected to the peripheral wall of the air inlet.

[0012] One of the above technical solutions has the following advantages or beneficial effects: the area covered by the mounting bracket is small, so when the first fan is working in cooling mode, the mounting bracket will not block too much cold air from entering the air supply duct through the air inlet, thus not affecting the cooling effect in the cooling room.

[0013] In some embodiments, the refrigeration compartment includes a telescopic assembly disposed within the evaporation chamber. A first end of the telescopic assembly is connected to the inner wall of the evaporation chamber, and a second end of the telescopic assembly extends toward the air inlet. A second fan is disposed at the second end of the telescopic assembly. The telescopic assembly has a first state and a second state: when the telescopic assembly is in the first state, the second end of the telescopic assembly can extend toward the air inlet, so that the second fan is disposed at the air inlet; when the telescopic assembly is in the second state, the second end of the telescopic assembly can retract away from the air inlet, so that the second fan is away from the air inlet.

[0014] One of the above technical solutions has the following advantages or beneficial effects: When the refrigeration equipment is in defrost mode, the telescopic component can be in a first state, and the second end of the telescopic component can extend towards the air inlet, so that the second fan is located at the air inlet. At this time, the second fan works, drawing air from the air supply duct at the air inlet and delivering the air from the air supply duct to the evaporator chamber through the air supply outlet. This allows the second fan to form a reverse airflow at the air inlet, blocking hot air from the evaporator chamber from flowing into the air supply duct, thereby preventing hot air from entering the refrigeration chamber and causing a large temperature rise in the refrigeration chamber, thus avoiding affecting the refrigeration effect of the refrigeration chamber. When the refrigeration equipment is in cooling mode, the telescopic component can be in a second state, and the second end of the telescopic component can retract away from the air inlet, so that the second fan is away from the air inlet. At this time, the second fan does not work, and the second fan can be deviated from the air inlet, thereby separating the second fan from the first fan. Therefore, the second fan will not block the air inlet in the cooling mode, and the first fan can form a positive airflow at the air inlet, so that the air in the evaporator can flow into the air supply duct through the air inlet, and then into the cooling room to achieve the cooling of the cooling room.

[0015] In some embodiments, the telescopic component extends along the height direction of the evaporation chamber; the upper end of the telescopic component is connected to the top wall of the evaporation chamber; the lower end of the telescopic component extends toward the air inlet and is connected to the second fan.

[0016] One of the above technical solutions has the following advantages or beneficial effects: by using the telescopic components arranged vertically, the telescopic components can drive the second fan to move upward or downward, so that the telescopic components can be set at the air inlet, and the reverse airflow generated by the second fan can block the hot air in the evaporator chamber from flowing into the air supply duct, thereby preventing hot air from entering the refrigeration room and causing a large temperature rise in the refrigeration room, thus avoiding affecting the refrigeration effect of the refrigeration room.

[0017] In some embodiments, the telescopic assembly includes at least a fixed cylinder and a telescopic rod. The fixed cylinder extends along the height direction of the evaporation chamber, and its upper end is connected to the top wall of the evaporation chamber. The telescopic rod is movably disposed inside the fixed cylinder and is connected to the second fan. When the telescopic assembly is in a first state, the telescopic rod can move along the length direction of the fixed cylinder towards the air inlet, so that the second fan is located at the air inlet. When the telescopic assembly is in a second state, the telescopic rod can move along the length direction of the fixed cylinder away from the air inlet, so that the second fan is away from the air inlet.

[0018] One of the above technical solutions has the following advantages or beneficial effects: When the telescopic component is in the first state, the second fan operates, drawing air from the air supply duct at the air inlet and delivering the air from the air supply duct to the evaporation chamber through the air outlet. This allows the second fan to create a reverse airflow at the air inlet, preventing hot air from the evaporation chamber from flowing into the air supply duct, thus avoiding hot air entering the cooling room and causing a large temperature rise in the cooling room, thereby preventing any impact on the cooling effect of the cooling room. When the telescopic component is in the second state, the second fan does not operate and can deviate from the air inlet, thus separating the second fan from the first fan. In cooling mode, the second fan will not block the air inlet, and the first fan can create a forward airflow at the air inlet, allowing air from the evaporation chamber to flow into the air supply duct through the air inlet and then into the cooling room, achieving cooling of the cooling room.

[0019] In some embodiments, the telescopic assembly extends horizontally along the evaporation chamber; the rear end of the telescopic assembly is connected to the side wall of the evaporation chamber, the front end of the telescopic assembly extends toward the air inlet, and the front end of the telescopic assembly is connected to the second fan.

[0020] One of the above technical solutions has the following advantages or beneficial effects: by using the horizontal arrangement of the telescopic component, the telescopic component can drive the second fan to move forward or backward, so that the telescopic component can be set at the air inlet, and then the reverse airflow generated by the second fan can block the hot air in the evaporator chamber from flowing into the air supply duct, thereby preventing hot air from entering the refrigeration room and causing a large temperature rise in the refrigeration room, thus avoiding affecting the refrigeration effect of the refrigeration room.

[0021] In some embodiments, the telescopic assembly includes at least a first sleeve and a second sleeve, the first sleeve and the second sleeve being coaxially arranged, the first sleeve being movably sleeved on the outside of the second sleeve, and the second sleeve being movably disposed inside the first sleeve and capable of sliding relative to each other along the axial direction of the first sleeve; the second sleeve is connected to the second fan; when the telescopic assembly is in a first state, the second sleeve can drive the second fan to move towards the air inlet, so that the second fan is disposed at the air inlet; when the telescopic assembly is in a second state, the second sleeve can drive the second fan to move away from the air inlet, so that the second fan is away from the air inlet.

[0022] One of the above technical solutions has the following advantages or beneficial effects: When the telescopic component is in the first state, the second sleeve can drive the second fan to move towards the air inlet, that is, the second sleeve can move the second fan forward so that the second fan is positioned at the air inlet. At this time, the second fan operates, drawing air from the air supply duct at the air inlet and delivering the air from the air supply duct to the evaporator chamber through the air supply outlet. This allows the second fan to form a reverse airflow at the air inlet, blocking hot air from the evaporator chamber from flowing into the air supply duct, thereby preventing hot air from entering the cooling room and causing a large temperature rise in the cooling room, thus avoiding affecting the cooling effect of the cooling room. When the telescopic component is in the second state, the second sleeve can move away from the air inlet along the axis of the first sleeve, that is, the second sleeve can move backward along the first sleeve, causing the second fan to move away from the air inlet. At this time, the second fan does not operate, and the second fan can deviate from the air inlet, thereby separating the second fan from the first fan. Therefore, the second fan will not block the air inlet in the cooling mode, and the first fan can form a positive airflow at the air inlet, so that the air in the evaporator can flow into the air supply duct through the air inlet, and then into the cooling room to achieve the cooling of the cooling room.

[0023] In some embodiments, the refrigeration chamber includes a rotating component disposed on the rear wall of the evaporation chamber and arranged opposite to the air inlet at a distance. A first end of the rotating component is rotatably connected to the rear wall of the evaporation chamber, and a second end of the rotating component is connected to a second fan. The rotating component has a first state and a second state: when the rotating component is in the first state, the rotating component can rotate towards the air inlet, such that the second fan is disposed at the side edge of the air inlet near the evaporator and arranged towards the evaporator; when the rotating component is in the second state, the rotating component can rotate away from the air inlet, such that the second fan is away from the air inlet and close to the rear wall of the evaporation chamber.

[0024] One of the above technical solutions has the following advantages or beneficial effects: When the refrigeration equipment is in refrigeration mode, the rotating component can be in the first state, rotating towards the air inlet, so that the second fan is located on the side edge of the air inlet near the evaporator and facing the evaporator. At this time, the second fan operates, drawing air from the air supply duct and blowing it towards the evaporator. This allows the airflow from the second fan to counteract the rising hot air, preventing hot air from the evaporator chamber from flowing into the air supply duct, thus avoiding a large amount of hot air entering the refrigeration chamber and causing a large temperature rise, thereby preventing any impact on the refrigeration effect. When the refrigeration equipment is in defrosting mode, the rotating component is in the second state, rotating away from the air inlet, so that the second fan is away from the air inlet and close to the rear wall of the evaporator chamber. At this time, the second fan does not operate. Therefore, by utilizing the fact that the second fan will not block the air inlet in cooling mode, the first fan can form a positive airflow at the air inlet, allowing the air in the evaporator chamber to flow into the air supply duct through the air inlet, and then into the cooling room, thereby achieving the cooling of the cooling room.

[0025] In some embodiments, the refrigeration chamber further includes a fixing member fixed to the side wall of the evaporation chamber, and the first end of the rotating member is rotatably connected to the fixing member.

[0026] One of the above technical solutions has the following advantages or beneficial effects: the rotating part can be rotatably connected to the fixed part to avoid the adapter being directly rotatably connected to the rear wall of the evaporation chamber, and the fixed part can make the rotation of the adapter smoother.

[0043] Typical embodiments embodying the features and advantages of this application will be described in detail in the following description. It should be understood that this application can have various variations in different embodiments, all of which do not depart from the scope of this application, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this application.

[0044] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0045] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0046] In existing refrigeration equipment, the evaporator is heated during defrosting, which generates hot air in the evaporation chamber. Since the evaporator remains connected to the refrigeration chamber during defrosting, the hot air in the evaporation chamber can easily blow into the refrigeration chamber, causing the temperature of the refrigeration chamber to rise and thus affecting the refrigeration effect inside the refrigeration chamber.

[0047] For ease of description, unless otherwise specified, the directions of up, down, left, right, front, and back in this article are based on the state of the refrigeration equipment when it is in use. The direction in which the refrigeration equipment faces the user is the front direction, and the direction in which it faces away from the user is the back direction. The vertical direction is up and down, and the horizontal direction is left and right.

[0048] like Figure 1 and Figure 2 As shown, a refrigeration device provided in one embodiment of this application may include a housing 1. The housing 1 may be constructed as the outer shell of the refrigeration device. The housing 1 may typically have a rectangular hollow structure. It should be noted that in other embodiments, the external shape of the housing 1 may be designed as needed, and is not limited here. The interior of the housing 1 may be used to provide installation space.

[0049] In some embodiments, a refrigeration compartment 20 may be formed inside the housing 1. The refrigeration compartment 20 can serve as an independent storage space, used as a refrigerator, freezer, etc., to meet different storage needs such as refrigeration and freezing depending on the type of stored items.

[0050] In some embodiments, a plurality of refrigeration chambers 20 may be provided inside the housing 1. The plurality of refrigeration chambers 20 may be arranged vertically or horizontally within the housing 1.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, a door 11 may be provided on the front side of the cabinet 1. The door 11 can be used to open and close the refrigeration compartment 20. The door 11 and the cabinet 1 can be connected by a hinge, so that the refrigerator door 11 can rotate around the axis of the hinge, thereby opening and closing the refrigerator door 11, and thus opening and closing the corresponding refrigeration compartment 20.

[0052] In some embodiments, multiple doors 11 may be provided. Multiple doors 11 may correspond one-to-one with multiple refrigeration compartments 20. It should be noted that in other embodiments, multiple doors 11 may simultaneously open and close a single refrigeration compartment 20.

[0053] like Figure 1 and Figure 2 As shown, in some embodiments, a liner 2 may be provided inside the housing 1. A refrigeration chamber 20 may be formed inside the liner 2. Multiple liner 2 may be provided inside the housing 1. The multiple liner 2 may be arranged vertically or horizontally within the housing 1. Each liner 2 may form one or more refrigeration chambers 20.

[0054] Figure 3 yes Figure 2 A sectional view.

[0055] like Figure 3As shown, in some embodiments, a refrigeration system may be installed inside the cabinet 1. The refrigeration system may be located inside the cabinet 1. The refrigeration system can be used to provide cold air to the inside of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 20.

[0056] In some embodiments, the refrigeration system may include a compressor (not shown in the figure). The compressor can compress the refrigerant, turning it into a high-temperature, high-pressure refrigerant vapor.

[0057] In some embodiments, the refrigeration system may include a condenser (not shown). A compressor delivers compressed refrigerant to the condenser. The condenser condenses the high-temperature, high-pressure refrigerant vapor.

[0058] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0059] In some embodiments, the refrigeration system may include an evaporator 3. A throttling device may deliver a throttled and depressurized refrigerant into the evaporator 3. The evaporator 3 may be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0060] In some embodiments, the compressor, condenser, throttling device, and evaporator 3 can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0061] In some embodiments, a compressor compartment may be provided inside the housing 1. The compressor compartment may be located in the bottom area of ​​the housing 1. The compressor compartment may be located below the rear side of the refrigeration compartment 20. The compressor compartment may be located below the rear side of the inner chamber 2. The compressor, condenser, etc., may be located inside the compressor compartment. When the compressor and condenser are working, they will dissipate heat, causing the temperature inside the compressor compartment to rise.

[0062] It should be noted that in some other embodiments, the press chamber may also be located in other positions within the housing 1.

[0063] In some embodiments, when the refrigerator is in cooling mode, the evaporator 3 operates and absorbs heat from the air around the evaporator 3 to form cold air around the evaporator 3. However, if the evaporator 3 operates for a long time, frost easily forms on its surface, which reduces the cooling effect of the evaporator 3 on the surrounding air. Therefore, it is necessary to defrost the surface of the evaporator 3.

[0064] In some embodiments, the evaporator 3 may be provided with a heating element (not shown in the figure). The heating element can be used to heat the surface of the evaporator 3. Thus, when the refrigerator is in defrost mode, the evaporator 3 stops working, the heater works, and heats the surface of the evaporator 3, so that hot air is formed around the evaporator 3 to melt the frost on the surface of the evaporator 3.

[0065] In some embodiments, the refrigeration equipment may include a refrigeration duct. The refrigeration duct may be provided with an air inlet 212. The air inlet 212 may connect the interior of the refrigeration duct and the refrigeration chamber 20. In this way, air in the refrigeration chamber 20 can enter the interior of the refrigeration duct for cooling to form cold air.

[0066] In some embodiments, the evaporator 3 can be located inside the refrigeration duct. When air from the refrigeration chamber 20 enters the refrigeration duct, it flows through the evaporator 3, where it exchanges heat with the evaporator 3. The evaporator 3 absorbs heat from the air, thereby cooling and condensing the air to form a large amount of cold air.

[0067] In some embodiments, the cooling duct may be equipped with an exhaust vent. The exhaust vent may connect the interior of the cooling duct and the cooling chamber 20. When air in the cooling chamber 20 enters the interior of the cooling duct through the air inlet 212, the cold air generated by the cooling duct's cooling process can be delivered to the interior of the cooling chamber 20 through the exhaust vent, thus cooling the interior of the cooling chamber 20 and achieving its cooling function. In this way, a cooling air circulation can be formed between the cooling chamber 20 and the interior of the cooling duct through the air inlet 212 and the exhaust vent.

[0068] Please see Figure 2 As shown, in some embodiments, the refrigeration device may include an evaporator chamber 21. The evaporator chamber 21 may be located in the rear region of the refrigeration chamber 20. The air inlet 212 of the refrigeration duct may be located on the side wall of the evaporator chamber 21. The air inlet 212 of the refrigeration duct may connect the interior of the evaporator chamber 21 and the refrigeration chamber 20. In this way, air in the refrigeration chamber 20 can enter the evaporator chamber 21 through the air inlet 212 of the refrigeration duct for cooling.

[0069] In some embodiments, the refrigeration equipment may include a first air duct housing 223. The first air duct housing 223 may be disposed on the back side of the refrigeration chamber 20. An evaporation chamber 21 may be formed between the first air duct housing 223 and the rear wall of the liner 2. An air inlet 212 may be formed on the bottom wall of the first air duct housing 223.

[0070] Please see Figure 2As shown, in some embodiments, the refrigeration equipment may include an air supply duct 22. The air supply duct 22 may be located between the refrigeration chamber 20 and the evaporation chamber 21. The back of the air supply duct 22 is connected to the evaporation chamber 21. The exhaust port of the refrigeration duct may be located on the side wall of the air supply duct 22. In this way, air in the evaporation chamber 21 can enter the air supply duct 22, and then be delivered to the refrigeration chamber 20 through the exhaust port of the refrigeration duct, thereby achieving refrigeration in the refrigeration chamber 20.

[0071] In some embodiments, the refrigeration device may include a second air duct housing 224. The second air duct housing 224 may be disposed over the front side of the first air duct housing 223, thereby forming an air supply duct 22 between the first air duct housing 223 and the second air duct housing 224. The exhaust port of the refrigeration air duct may be formed on the front wall or other side wall of the second air duct housing 224.

[0072] Please see Figure 2 As shown, in some embodiments, an air inlet 221 may be provided on the side wall of the air supply duct 22. The air inlet 221 may be provided on the side wall of the first air duct shell 223. The air inlet 221 may connect the evaporation chamber 21 and the air supply duct 22, so that the cold air in the evaporation chamber 21 can enter the air supply duct 22 through the air inlet 221.

[0073] Please see Figure 2 As shown, in some embodiments, an air outlet 222 may be provided on the side wall of the air supply duct 22. The air outlet 222 may be provided on the side wall of the second air duct shell 224. The air outlet 222 may serve as the exhaust port of the cooling air duct. The air outlet 222 may connect the air supply duct 22 and the cooling chamber 20, so that the cold air in the evaporator chamber 21 can enter the air supply duct 22 through the air inlet 221, and be discharged into the cooling chamber 20 through the air outlet 222 of the air supply duct 22, thereby achieving cooling in the cooling chamber 20.

[0074] In some embodiments, the air supply duct 22 may be provided with multiple air outlets 222. The multiple air outlets 222 may be arranged at intervals on the air supply duct 22. The multiple air outlets 222 may be arranged at intervals on the rear wall of the cooling chamber 20. The multiple air outlets 222 may be arranged vertically at intervals, or horizontally at intervals. In this way, the cold air entering the air supply duct 22 from the evaporator 21 can be delivered to different areas of the cooling chamber 20 through the multiple air outlets 222, thereby improving the uniformity of temperature distribution within the cooling chamber 20.

[0075] It should be noted that the number and position of the air outlets 222 on the air supply duct 22 can be adjusted as needed, and no restrictions are imposed here.

[0076] Please see Figure 2As shown, in some embodiments, the refrigeration equipment may include a first fan 4. The first fan 4 may be located inside the air supply duct 22. The first fan 4 may be used to draw air from the evaporation chamber 21 through the air inlet 221 and deliver the drawn air to the refrigeration chamber 20 through the air supply duct 22. In this way, the first fan 4 can draw air from the evaporation chamber 21, making the evaporation chamber 21 negative pressure, so that the air in the refrigeration chamber 20 actively enters the negative pressure evaporation chamber 21 through the air inlet 212, and comes into contact with the evaporator 3 in the evaporation chamber 21 for cooling. The cooled air then returns to the refrigeration chamber 20 through the air inlet 221 and the air supply duct 22.

[0077] In some embodiments, the first fan 4 can be located at the air inlet 221. The side of the first fan 4 closest to the air inlet 221 can be the air intake side of the first fan 4, so that the first fan 4 can draw cold air from the evaporation chamber 21 through the air inlet 221. In this way, the first fan 4 can draw air from the evaporation chamber 21 more efficiently, thereby improving the extraction efficiency of the first fan 4.

[0078] In some embodiments, the first fan 4 can blow air to its periphery. As a result, the cold air in the evaporation chamber 21, after passing through the air inlet 221, can be blown from the periphery of the first fan 4 into the air supply duct 22, and then enter the cooling chamber 20 through the air outlet 222 on the second air duct shell 224, thereby achieving cooling of the cooling chamber 20.

[0079] It should be noted that in some other embodiments, the air outlet side of the first fan 4 may be located on the side of the first fan 4 away from the air inlet 221 or on another side.

[0080] Please see Figure 2 As shown, in some embodiments, the refrigeration equipment may include a second fan 5. The second fan 5 may be located at the air inlet 221. The second fan 5 may be used to draw air from the air supply duct 22 through the air inlet 221 and deliver the drawn air to the evaporation chamber 21 through the air inlet 221.

[0081] Therefore, when the refrigeration equipment is in cooling mode, the first fan 4 draws cold air from the evaporator chamber 21 and delivers it to the refrigeration chamber 20 through the air inlet 221, the air supply duct 22, and the air outlet 222, thereby achieving the cooling effect of the refrigeration equipment. When the refrigeration equipment is in defrosting mode, the second fan 5 draws air from the air supply duct 22 and delivers the air from the air supply duct 22 in the opposite direction to the evaporator chamber 21 through the air inlet 221. This prevents the hot air generated during the defrosting of the evaporator 3 from entering the refrigeration chamber 20 through the air supply duct 22, thus reducing temperature changes in the refrigeration chamber 20 during defrosting and avoiding affecting its cooling effect. Simultaneously, because the temperature rise in the refrigeration chamber 20 is not significant, after defrosting and returning to cooling mode, the refrigeration chamber 20 can quickly recover to the required low-temperature environment, saving time and costs associated with the recovery of the refrigeration chamber 20.

[0082] In some embodiments, when the refrigeration equipment is in refrigeration mode, the first fan 4 operates while the second fan 5 does not operate. As a result, the cold air in the evaporation chamber 21 can be blown into the air supply duct 22 by the first fan 4, while the air in the air supply duct 22 will not be blown into the evaporation chamber 21 by the second fan 5. This allows all the air in the air supply duct 22 to be delivered into the refrigeration chamber 20, thereby improving the refrigeration effect in the refrigeration chamber 20.

[0083] In some embodiments, when the refrigeration equipment is in defrost mode, the first fan 4 does not work, while the second fan 5 works. Thus, when the evaporator 3 is defrosting, the first fan 4 will not draw hot air from the evaporation chamber 21, preventing hot air from the evaporation chamber 21 from quickly entering the air supply duct 22.

[0084] In some embodiments, the power of the second fan 5 is less than that of the first fan 4. The lower power of the second fan 5 prevents the second fan 5 from blowing hot air from the evaporator chamber 21 into the cooling chamber 20 through the air inlet 212, thereby preventing excessive temperature changes inside the cooling equipment and ensuring the cooling effect of the cooling chamber 20.

[0085] In some embodiments, the airflow blown by the second fan 5 into the evaporation chamber 21 can mix and convect with the rising hot air in the evaporation chamber 21, so that the mixed airflow can circulate in the evaporation chamber 21 without flowing into the air supply duct 22 through the air inlet 221.

[0086] In some embodiments, the second fan 5 can draw cold air from the cooling chamber 20 through the air inlet 221, the air supply duct 22 and the air outlet 222, so that some of the cold air in the cooling chamber 20 can enter the evaporation chamber 21 and counteract the hot air rising in the evaporation chamber 21, thereby reducing the temperature in the evaporation chamber 21.

[0087] Please see Figure 3 and Figure 4 As shown, in some embodiments, the second fan 5 can be fixed at the air inlet 221. The second fan 5 can be arranged opposite to the first fan 4.

[0088] In some embodiments, the second fan 5 may have a small number of blades, resulting in a relatively low power output. Consequently, the area covered by the second fan 5 at the air inlet 221 is small, and therefore, in cooling mode, when the first fan 4 is operating, the second fan 5 will not obstruct too much cold air from entering the air supply duct 22 through the air inlet 221, thus not affecting the cooling effect in the cooling room 20.

[0089] In some embodiments, the refrigeration equipment includes a mounting bracket 6. The mounting bracket 6 can be fixed at the air inlet 221. The second fan 5 is rotatably mounted on the mounting bracket 6. Thus, the mounting bracket 6 enables the second fan 5 to rotate stably at the air inlet 221, improving the stability of the second fan 5's rotation at the air inlet 221.

[0090] In some embodiments, the mounting bracket 6 may be disposed inside the evaporation chamber 21. The second fan 5 may be disposed on the side of the mounting bracket 6 near the air inlet 221.

[0091] It should be noted that in some other embodiments, the second fan 5 may also be located inside the evaporation chamber 21, and the air outlet of the second fan 5 may face the air inlet 221.

[0092] Please see Figure 3 and Figure 4 As shown, in some embodiments, the mounting bracket 6 can be elongated. The mounting bracket 6 can be disposed at the air inlet 221. The end of the mounting bracket 6 can be connected to the peripheral sidewall of the air inlet 221. Thus, by using the rod-shaped mounting bracket 6, the area covered by the mounting bracket 6 in the air inlet 221 is minimized. Consequently, in cooling mode, when the first fan 4 is operating, the mounting bracket 6 will not obstruct too much cold air from entering the air supply duct 22 through the air inlet 221, thereby not affecting the cooling effect in the cooling chamber 20.

[0093] It should be noted that in some other embodiments, the mounting bracket 6 may be triangular or other shapes.

[0094] In some embodiments, a mounting post 2231 is provided on the rear wall of the first air duct housing 223. The mounting post 2231 may protrude from the rear wall of the first air duct housing 223. A mounting hole may be provided on the mounting post 2231. A fixing hole 61 may be provided on the mounting bracket 6. The mounting bracket 6 and the mounting post 2231 can be fixed together through the mounting hole and the fixing hole 61, and the mounting hole and the fixing hole 61 can be fixedly connected by fasteners. Thus, the mounting bracket 6 and the first air duct housing 223 are fixed together through the mounting hole on the mounting post 2231 and the fixing hole 61 on the mounting bracket 6, thereby improving the stability of the mounting bracket 6 in the evaporation chamber 21, and thus improving the stability of the second fan 5.

[0095] In some embodiments, the mounting bracket 6 may be arranged to extend radially along the air inlet 221. The second fan 5 is rotatably mounted in the middle of the mounting bracket 6. The second fan 5 may be directly opposite the air inlet 221. Thus, the second fan 5 can minimize the entry of hot air rising in the evaporator chamber 21 into the air supply duct 22, thereby ensuring that the temperature change in the cooling chamber 20 is minimal and does not affect the cooling effect in the cooling chamber 20.

[0096] It should be noted that in some other embodiments, the mounting bracket 6 may be located on the periphery of the air inlet 221 or elsewhere.

[0097] Please see Figure 5 and Figure 6 As shown, in some embodiments, the refrigeration device may include a telescopic assembly 7. The telescopic assembly 7 may be disposed within the evaporation chamber 21. A first end of the telescopic assembly 7 is connected to the inner wall of the evaporation chamber 21. A second end of the telescopic assembly 7 extends in the opposite direction to the air inlet 221. A second fan 5 is disposed at the second end of the telescopic assembly 7. The telescopic assembly 7 may have a first state and a second state.

[0098] When the refrigeration equipment is in defrosting mode, the telescopic component 7 can be in the first state. The second end of the telescopic component 7 can extend towards the air inlet 221, so that the second fan 5 is located at the air inlet 221. At this time, the second fan 5 works, and the second fan 5 draws air from the air supply duct 22 at the air inlet 221 and delivers the air from the air supply duct 22 to the evaporation chamber 21 through the air outlet. This allows the second fan 5 to form a reverse airflow at the air inlet 221, blocking the hot air in the evaporation chamber 21 from flowing into the air supply duct 22. This prevents hot air from entering the refrigeration chamber 20 and causing a large temperature rise in the refrigeration chamber 20, thereby avoiding affecting the refrigeration effect of the refrigeration chamber 20.

[0099] When the refrigeration equipment is in cooling mode, the telescopic component 7 can be in a second state, and the second end of the telescopic component 7 can retract away from the air inlet 221, causing the second fan 5 to move away from the air inlet 221. At this time, the second fan 5 is not working, and the second fan 5 can deviate from the air inlet 221, thereby separating the second fan 5 from the first fan 4. Thus, the second fan 5 will not block the air inlet 221 in cooling mode, and the first fan 4 can form a positive airflow at the air inlet 221, allowing the air in the evaporator chamber 21 to flow into the air supply duct 22 through the air inlet 221, and then into the cooling chamber 20, thereby achieving cooling in the cooling chamber 20.

[0100] Please see Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the telescopic component 7 can extend along the height direction of the evaporation chamber 21. The evaporation chamber 21 can extend vertically. The upper end of the telescopic component 7 can be connected to the top wall of the evaporation chamber 21, and the lower end of the telescopic component 7 extends towards the air inlet 221, and the lower end of the telescopic component 7 is connected to the second fan 5. Thus, by using the vertical arrangement of the telescopic component 7, the telescopic component 7 can drive the second fan 5 to move up or down, thereby allowing the telescopic component 7 to be positioned at the air inlet 221. The reverse airflow generated by the second fan 5 then blocks the hot air in the evaporation chamber 21 from flowing into the air supply duct 22, thereby preventing hot air from entering the cooling chamber 20 and causing a large temperature rise in the cooling chamber 20, thus avoiding affecting the cooling effect of the cooling chamber 20.

[0101] Please see Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the telescopic assembly 7 includes a fixed cylinder 71. The fixed cylinder 71 may be cylindrical. The fixed cylinder 71 may extend along the height direction of the evaporation chamber 21. The upper end of the fixed cylinder 71 may be connected to the top wall of the evaporation chamber 21. The fixed cylinder 71 has a lifting cavity 711 inside. The extending direction of the lifting cavity 711 is the same as the extending direction of the fixed cylinder 71.

[0102] In some embodiments, the telescopic assembly 7 includes a telescopic rod 72. The telescopic rod 72 is movably disposed inside the fixed cylinder 71. The telescopic rod 72 can be connected to the second fan 5.

[0103] When the telescopic assembly 7 is in the first state, the telescopic rod 72 can move along the length of the fixed cylinder 71 towards the air inlet 221, that is, the telescopic rod 72 can move downward along the lifting chamber 711 so that the second fan 5 is positioned at the air inlet 221. At this time, the second fan 5 operates, drawing air from the air supply duct 22 at the air inlet 221 and delivering the air from the air supply duct 22 to the evaporation chamber 21 through the air outlet. This allows the second fan 5 to create a reverse airflow at the air inlet 221, preventing hot air from flowing into the air supply duct 22 from the evaporation chamber 21. This prevents hot air from entering the cooling chamber 20 and causing a large temperature rise in the cooling chamber 20, thereby avoiding affecting the cooling effect of the cooling chamber 20.

[0104] When the telescopic assembly 7 is in the second state, the telescopic rod 72 can move away from the air inlet 221 along the length of the fixed cylinder 71, that is, the telescopic rod 72 can move upward along the lifting chamber 711, causing the second fan 5 to move away from the air inlet 221. At this time, the second fan 5 is not working, and the second fan 5 can deviate from the air inlet 221, thereby separating the second fan 5 from the first fan 4. Thus, the second fan 5 will not block the air inlet 221 in the cooling mode, and the first fan 4 can form a positive airflow at the air inlet 221, so that the air in the evaporator chamber 21 can flow into the air supply duct 22 through the air inlet 221, and then into the cooling chamber 20, thereby achieving the cooling of the cooling chamber 20.

[0105] Please see Figure 7 As shown, in some embodiments, the top of the telescopic rod 72 may be provided with a protrusion 721. The edge of the protrusion 721 can protrude beyond the top of the telescopic rod 72. A limiting part 712 is provided on the inner wall of the fixed cylinder 71. The limiting part 712 is annular. The limiting part 712 has a central opening, through which the telescopic rod 72 can move up and down, thereby realizing the switching of the telescopic assembly 7 between the first state and the second state. When the telescopic assembly 7 is in the first state, the telescopic rod 72 moves downward along the lifting cavity 711, and the edge of the protrusion 721 can abut against the limiting part 712. At this time, the second fan 5 is located at the air inlet 221. Thus, the protrusion 721 and the limiting part 712 can be used to position the second fan 5 and prevent the telescopic rod 72 from directly detaching from the bottom of the fixed cylinder 71, thereby limiting the telescopic rod 72.

[0106] Please see Figure 8 and Figure 9As shown, in some embodiments, the telescopic component 7 can extend horizontally along the evaporation chamber 21. The rear end of the telescopic component 7 can be connected to the rear wall of the evaporation chamber 21, and the front end of the telescopic component 7 extends towards the air inlet 221, and the front end of the telescopic component 7 is connected to the second fan 5. Thus, by utilizing the horizontal arrangement of the telescopic component 7, the telescopic component 7 can drive the second fan 5 to move forward or backward, thereby allowing the telescopic component 7 to be positioned at the air inlet 221. The reverse airflow generated by the second fan 5 then blocks the hot air in the evaporation chamber 21 from flowing into the air supply duct 22, thereby preventing hot air from entering the cooling chamber 20 and causing a large temperature rise in the cooling chamber 20, thus avoiding affecting the cooling effect of the cooling chamber 20.

[0107] It should be noted that in some other embodiments, the telescopic component 7 may also be arranged to extend horizontally along the evaporation chamber 21. The left end of the telescopic component 7 can be connected to the left side wall of the evaporation chamber 21, and the right end of the telescopic component 7 extends toward the air inlet 221 and is connected to the second fan 5.

[0108] It should also be noted that, in another embodiment, the telescopic component 7 can also be arranged to extend horizontally along the evaporation chamber 21. The right end of the telescopic component 7 can be connected to the right side wall of the evaporation chamber 21, and the left end of the telescopic component 7 extends toward the air inlet 221, and the left end of the telescopic component 7 is connected to the second fan 5.

[0109] In some embodiments, the refrigeration device includes a driving member. When the telescopic device is in the first state, the driving member can drive the telescopic rod to move along the length direction of the fixed cylinder 71 toward the air inlet 221, that is, the driving member can drive the telescopic rod 72 to move downward along the lifting cavity 711, so that the second fan 5 is located at the air inlet 221.

[0110] In some embodiments, when the telescopic device is in the second state, the driving member can drive the telescopic rod 72 to move away from the air inlet 221 along the length direction of the fixed cylinder 71, that is, the telescopic rod 72 can move upward along the lifting cavity 711, so that the second fan 5 moves away from the air inlet 221.

[0111] Please see Figure 8 , Figure 9 and Figure 10 As shown, in some embodiments, the telescopic assembly 7 may include a first sleeve 73 and a second sleeve 74. The first sleeve 73 and the second sleeve 74 may be coaxially arranged. The first sleeve 73 is movably sleeved on the outside of the second sleeve 74. The second sleeve 74 is movably disposed inside the first sleeve 73 and can slide relative to it along the axial direction of the first sleeve 73. The second sleeve 74 is connected to the second fan 5.

[0112] When the telescopic component 7 is in the first state, the second sleeve 74 can drive the second fan 5 to move towards the air inlet 221. That is, the second sleeve 74 can move the second fan 5 forward so that the second fan 5 is positioned at the air inlet 221. At this time, the second fan 5 works, drawing air from the air supply duct 22 at the air inlet 221 and delivering the air from the air supply duct 22 to the evaporator chamber 21 through the air outlet. This allows the second fan 5 to create a reverse airflow at the air inlet 221, preventing hot air from flowing into the air supply duct 22 from the evaporator chamber 21. This prevents hot air from entering the cooling chamber 20 and causing a large temperature rise in the cooling chamber 20, thus avoiding affecting the cooling effect of the cooling chamber 20.

[0113] When the telescopic component 7 is in the second state, the second sleeve 74 can move away from the air inlet 221 along the axial direction of the first sleeve 73, that is, the second sleeve 74 can move backward along the first sleeve 73, causing the second fan 5 to move away from the air inlet 221. At this time, the second fan 5 is not working, and the second fan 5 can deviate from the air inlet 221, thereby separating the second fan 5 from the first fan 4. Thus, the second fan 5 will not block the air inlet 221 in the cooling mode, and the first fan 4 can form a positive airflow at the air inlet 221, so that the air in the evaporator chamber 21 can flow into the air supply duct 22 through the air inlet 221, and then into the cooling chamber 20, thereby achieving the cooling of the cooling chamber 20.

[0114] In some embodiments, when the telescopic device is in the first state, the driving member can drive the second sleeve 74 to move the second fan 5 toward the air inlet 221, that is, the second sleeve 74 can move the second fan 5 forward so that the second fan 5 is located at the air inlet 221.

[0115] In some embodiments, when the telescopic device is in the second state, the driving member can drive the second sleeve 74 to move away from the air inlet 221 along the axial direction of the first sleeve 73, that is, the second sleeve 74 can move backward along the first sleeve 73, so that the second fan 5 moves away from the air inlet 221.

[0116] Please see Figure 10 As shown, in some embodiments, the telescopic assembly 7 may further include a third sleeve 75. The third sleeve 75 may be coaxially arranged with the first sleeve 73 and the second sleeve 74. The third sleeve 75 is movably sleeved on the outside of the first sleeve 73. The first sleeve 73 is movably disposed within the third sleeve 75 and can slide relative to it along the axial direction of the third sleeve 75. The second sleeve 74 is movably disposed within the third sleeve 75 and can slide relative to it along the axial direction of the third sleeve 75.

[0117] It should be noted that in some other embodiments, the sleeve may have multiple sections, and adjacent sleeves may extend and retract coaxially.

[0118] Please see Figure 10 and Figure 11 As shown, in some embodiments, a snap-fit ​​groove 211 is provided on the rear wall of the evaporation chamber 21. The third sleeve 75 is telescopically disposed within the snap-fit ​​groove 211. When the third sleeve 75 moves along the snap-fit ​​groove 211 toward the air inlet 221, the first sleeve 73 moves along the third sleeve 75 toward the air inlet 221, and the second sleeve 74 moves along the first sleeve 73 toward the air inlet 221, the second fan 5 connected to the rear end of the second sleeve 74 can be disposed at the air inlet 221, so that the telescopic component 7 can be in the first state.

[0119] Please see Figure 10 and Figure 11 As shown, in some embodiments, a snap-fit ​​portion 2111 is provided at the opening of the snap-fit ​​groove 211. The snap-fit ​​portion 2111 is formed by extending inward from the peripheral edge of the snap-fit ​​groove 211. The snap-fit ​​portion 2111 may be annular. A third protruding ring 751 may extend outward from the rear end edge of the third sleeve 75. When the third sleeve 75 moves along the snap-fit ​​groove 211 toward the air inlet 221, the third protruding ring 751 can abut against the snap-fit ​​portion 2111 to prevent the third sleeve 75 from disengaging from the snap-fit ​​groove 211.

[0120] Please see Figure 10 and Figure 11 As shown, in some embodiments, a third retaining ring 752 may extend inward from the front edge of the third sleeve 75. The third retaining ring 752 is annular. A first protruding ring 731 may extend from the rear edge of the first sleeve 73. When the first sleeve 73 moves axially toward the air inlet 221 along the third sleeve 75, the first protruding ring 731 can abut against the third retaining ring 752 to prevent the first sleeve 73 from disengaging from the third sleeve 75.

[0121] Please see Figure 10 and Figure 11 As shown, in some embodiments, a first retaining ring 732 may extend inward from the front end edge of the first sleeve 73. The first retaining ring 732 is annular. A second protruding ring 741 may extend from the rear end edge of the second sleeve 74. When the second sleeve 74 moves axially toward the air inlet 221 along the first sleeve 73, the second protruding ring 741 can abut against the first retaining ring 732 to prevent the second sleeve 74 from disengaging from the first sleeve 73.

[0122] Please see Figure 12 , Figure 13 and Figure 14As shown, in some embodiments, the refrigeration chamber 20 includes a rotating member 8. The rotating member 8 may be disposed on the rear wall of the evaporation chamber 21 and arranged at a distance from the air inlet 221. A first end of the rotating member 8 may be rotatably connected to the rear wall of the evaporation chamber 21. A second end of the rotating member 8 may be connected to a second fan 5. The rotating member 8 has a first state and a second state.

[0123] When the refrigeration equipment is in refrigeration mode, the rotating part 8 can be in the first state, and the rotating part 8 can rotate towards the air inlet 221, so that the second fan 5 is located on the side edge of the air inlet 221 near the evaporator 3 and is arranged towards the evaporator 3. At this time, the second fan 5 works, and the second fan 5 can draw air from the air supply duct 22 and blow the air in the air supply duct 22 towards the evaporator 3, so that the airflow blown out by the second fan 5 can resist the rising hot air, preventing the hot air in the evaporator chamber 21 from flowing into the air supply duct 22, thereby preventing a large amount of hot air from entering the refrigeration chamber 20 and causing a large temperature rise in the refrigeration chamber 20, thus avoiding affecting the refrigeration effect of the refrigeration chamber 20.

[0124] When the refrigeration equipment is in defrosting mode, the rotating part 8 is in the second state, and can rotate away from the air inlet 221, causing the second fan 5 to move away from the air inlet 221 and closer to the rear wall of the evaporator chamber 21. At this time, the second fan 5 is not working. Thus, by utilizing the fact that the second fan 5 does not block the air inlet 221 in cooling mode, the first fan 4 can form a positive airflow at the air inlet 221, allowing the air in the evaporator chamber 21 to flow into the air supply duct 22 through the air inlet 221, and then into the refrigeration chamber 20, thereby achieving the cooling of the refrigeration chamber 20.

[0125] In some embodiments, the refrigeration compartment 20 further includes a fixing member 9. The fixing member 9 can be fixed to the side wall of the evaporation chamber 21. The first end of the rotating member 8 is rotatably connected to the fixing member 9. Thus, the rotating member 8 can be rotatably connected to the fixing member 9 to prevent the adapter from being directly rotatably connected to the rear wall of the evaporation chamber 21, and the fixing member 9 makes the rotation of the adapter smoother.

[0126] In some embodiments, when the rotating device is in the first state, the driving member can drive the rotating member 8 to rotate toward the air inlet 221, so that the second fan 5 is located at the side edge of the air inlet 221 near the evaporator 3 and is arranged toward the evaporator 3.

[0127] In some embodiments, when the rotating member 8 is in the second state, the driving member can drive the rotating member 8 to rotate in a direction away from the air inlet 221, so that the second fan 5 moves away from the air inlet 221 and closer to the rear wall of the evaporation chamber 21.

[0128] Please see Figure 14As shown, in some embodiments, the adapter 8 may have a connecting portion 81 and a bending portion 82. One end of the connecting portion 81 is rotatably connected to the fixing member 9. The other end of the connecting portion 81 is connected to one end of the bending portion 82. The other end of the bending portion 82 is connected to the second fan. The connecting portion 81 and the bending portion 82 are arranged perpendicularly. Thus, when the connecting portion 81 rotates to a horizontal position relative to the fixing member 9, the connection portion 81 and the fixing member 9 can be stabilized. At this time, the bending portion 82 can drive the second fan 5 to be arranged towards the evaporator 3, so that the airflow blown by the second fan 5 can meet the rising hot air and prevent the hot air in the evaporation chamber 21 from flowing into the air supply duct 22.

[0129] It should be noted that in some other embodiments, the connecting portion 81 and the bending portion 82 may be at an angle of 60 degrees or other angles.

[0130] Please see Figure 15 As shown, in some embodiments, a support portion 91 protrudes from the side wall of the fixing plate facing the air inlet. The support portion 91 can be arranged horizontally. When the connecting portion 81 rotates to a horizontal position relative to the fixing member 9, the connecting portion 81 can be supported on the support portion 91. At this time, the bending portion 82 can drive the second fan 5 to be arranged towards the evaporator 3. Thus, the stability of the adapter in the first state can be improved by using the support portion 91.

Since this application can be embodied in many forms without departing from its spirit or substance, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
