Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, refrigerators and freezers have refrigeration compartments that create a refrigerated environment for storing goods.

[0003] The compressor compartment of a refrigerator is usually designed with a ventilation structure. Sufficient ventilation space can promote air circulation in the compressor compartment, reduce the temperature of the compressor compartment, and indirectly improve the overall performance of the refrigerator.

[0004] In the current market, the ventilation structure of the compressor compartment in built-in refrigerators is usually designed on the side wall or back of the cabinet. When the refrigerator is embedded in the cabinet, a certain amount of heat dissipation space usually needs to be reserved, which results in a loss of refrigerator volume and a reduction in the usable space of the built-in refrigerator. Utility Model Content

[0005] The purpose of this utility model is to provide a refrigeration device that, when embedded in a cabinet, eliminates the need to reserve space for heat dissipation inside the cabinet, thereby increasing the usable volume of the refrigeration device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a compressor compartment is provided at the bottom of the housing, and a ventilation channel is provided at the back of the housing, the ventilation channel extending along the height direction of the refrigeration device, the upper end of the ventilation channel extending to the top of the housing; a centrifugal fan is provided at the back of the compressor compartment, the air inlet of the centrifugal fan is connected to the compressor compartment, the air outlet of the centrifugal fan is arranged upward, and the air outlet of the centrifugal fan is connected to the lower end of the ventilation channel; a condenser is provided inside the compressor compartment and is arranged opposite to the air inlet of the centrifugal fan; the centrifugal fan is configured such that when the centrifugal fan is running, the centrifugal fan can draw air from the compressor compartment to form an airflow, the airflow can flow through the condenser, then enter the centrifugal fan, and then be conveyed upward along the ventilation channel through the air outlet of the centrifugal fan.

[0008] The above technical solution has the following advantages or beneficial effects: The ventilation channel is designed at the back of the cabinet and extends along the height of the refrigeration unit, reaching the top of the cabinet. The centrifugal fan transports the air in the compressor compartment upwards to the ventilation channel for heat dissipation. On the one hand, by placing the condenser on the ventilation channel, the ventilation channel can serve as a heat dissipation space for the compressor compartment. When the refrigeration unit is embedded in the cabinet, there is no need to reserve additional heat dissipation space like traditional built-in refrigerators. The embedded refrigeration unit of this solution can make full use of the cabinet space, increasing the effective volume of the refrigerator. Users can place more items, improving the volume utilization rate of the refrigerator. On the other hand, due to the excellent centralized airflow performance of the centrifugal fan, when the centrifugal fan is running, it can quickly draw air from the compressor compartment to form an airflow. Since the condenser is positioned relative to the air inlet side of the centrifugal fan, the airflow can flow through the condenser and carry away the heat on the condenser surface before entering the air inlet. After leaving through the air outlet of the centrifugal fan, it is transported upwards along the ventilation channel. This allows the air in the compressor compartment to be efficiently drawn out, forming a good air circulation and effectively reducing the temperature inside the compressor compartment. Moreover, centrifugal fans are smaller in size than axial fans, which can save space in the compressor compartment and facilitate a compact spatial layout of the compressor compartment.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein the bottom of the compressor chamber is provided with a heat dissipation air inlet; the air inlet is disposed facing the heat dissipation air inlet; and the condenser is disposed between the heat dissipation air inlet and the air inlet of the centrifugal fan.

[0010] Another technical solution described above has the following advantages or beneficial effects: By placing the condenser between the heat dissipation air inlet and the centrifugal fan inlet, outside air can directly enter the compressor chamber through the heat dissipation air inlet, and first flow through the condenser before flowing into the centrifugal fan. Compared to placing the condenser at the centrifugal fan outlet, this reduces the efficiency loss caused by the airflow carrying away some heat through the compressor chamber before cooling the condenser. When the air outside the compressor chamber flows through the condenser, it can fully absorb the heat released by the condenser, thereby lowering the condenser temperature. The centrifugal fan can efficiently extract the air heated by the condenser, forming a continuous airflow circulation, enhancing the condenser's heat dissipation effect and improving the cooling performance of the refrigeration unit.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein the heat dissipation air inlet is located at the bottom front side of the compressor chamber; the air inlet is located at the front side of the centrifugal fan, and the air outlet is located at the top of the centrifugal fan, with the top of the centrifugal fan correspondingly connected to the lower end of the ventilation channel; and the condenser is spaced apart and arranged in front of the air inlet.

[0012] Another technical solution described above has the following advantages or beneficial effects: By setting an air inlet at the front of the centrifugal fan and an air outlet at the top connected to the lower end of the ventilation duct, the centrifugal fan's ability to change airflow direction by 90 degrees creates a directional airflow path within the compressor chamber and the ventilation duct. Specifically, air is drawn in from the front of the centrifugal fan, flows through the condenser, and then enters the centrifugal fan along its axial direction. After being accelerated by the centrifugal fan, it is discharged upwards from the top and directly into the ventilation duct. The directional airflow created by the centrifugal fan reduces disordered diffusion and mixing of airflow within the chamber, reduces airflow resistance, and allows for smoother airflow, thereby improving ventilation efficiency.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein a water receiving tray is provided at the bottom of the compressor chamber, and a heat dissipation air inlet is provided at the bottom front side of the water receiving tray; a centrifugal fan is provided above the water receiving tray, and the bottom of the centrifugal fan is supported at the rear side of the water receiving tray; a condenser is provided above the water receiving tray, and the bottom of the condenser is supported at the front side of the water receiving tray.

[0014] Another technical solution described above has the following advantages or beneficial effects: a water collection tray is installed at the bottom of the compressor chamber, and the centrifugal fan and condenser are respectively located behind the water collection tray. The water collection tray provides an installation foundation for the condenser and centrifugal fan, and facilitates a compact layout. Moreover, when the centrifugal fan starts, it creates a negative pressure inside the compressor chamber, and external cold air naturally enters from the heat dissipation inlet and flows through the condenser. During this process, it absorbs the heat dissipated by the condenser. Then, under the action of the centrifugal fan, the airflow continues to flow upward, enters the inlet of the centrifugal fan, and is then blown out from the outlet of the centrifugal fan into the ventilation channel for discharge, thus achieving a good heat dissipation effect on the compressor chamber and condenser.

[0015] In some embodiments of this application, a refrigeration device is provided, the refrigeration device including a mounting frame, the condenser being disposed through the rear wall of the mounting frame; a ventilation channel is formed between the mounting frame and the front wall of the compressor compartment, the heat dissipation air inlet is located at the bottom of the ventilation channel and communicates with the ventilation channel; when the centrifugal fan is started, air outside the compressor compartment enters the ventilation channel through the heat dissipation air inlet, flows through the condenser and then flows to the air inlet.

[0016] Another technical solution mentioned above has the following advantages or beneficial effects: By placing the drain pipe in the interval area, the idle interval area between the condenser and the centrifugal fan can be fully utilized, making the layout inside the compressor chamber more compact and reasonable, and improving space utilization. Moreover, when the centrifugal fan is working, the air flows through the condenser and then through the water collection pan and drain pipe. Under the suction action of the centrifugal fan, the drain pipe is disturbed, and the air flow efficiency in the water collection pan can be improved, thereby improving the liquid evaporation efficiency in the water collection pan and reducing the temperature of the compressor chamber.

[0017] In some embodiments of this application, a refrigeration device is provided. The mounting bracket includes a connecting wall disposed on the top of the condenser; a first mounting wall connected to one end of the connecting wall, the first mounting wall extending downward from one end of the connecting wall and disposed on one side of the condenser; a second mounting wall connected to the other end of the connecting wall, the second mounting wall extending downward from the other end of the connecting wall and disposed on the other side of the condenser; the side of the second mounting wall away from the connecting wall extending forward, and the connecting wall, the first mounting wall, the second mounting wall, and the front wall of the compressor compartment forming the ventilation channel.

[0018] Another technical solution described above has the following advantages or beneficial effects: By extending the second mounting wall forward from the side away from the connecting wall, the front side of the second mounting wall can abut against the front wall of the compressor compartment, thus forming a ventilation channel together with the connecting wall, the first mounting wall, and the front wall of the compressor compartment. In this way, the structure of the mounting frame can define the ventilation channel within the compressor compartment, guiding air to flow more smoothly. The airflow entering the compressor compartment from the heat dissipation inlet can flow more orderly along the ventilation channel, sequentially passing through the condenser and centrifugal fan, reducing turbulence and resistance during airflow, improving airflow efficiency, and thereby enhancing the heat dissipation effect of the condenser.

[0019] In some embodiments of this application, a refrigeration device is provided, wherein a connecting column is provided in the water receiving tray, the connecting column extends along the height direction of the water receiving tray, the lower end of the connecting column is connected to the bottom wall of the water receiving tray, the upper end of the connecting column extends upward, and the upper end of the connecting column is spaced below the top opening of the water receiving tray; the bottom of the condenser is connected to the upper end of the connecting column, and the bottom of the condenser extends into the water receiving tray through the top opening of the water receiving tray.

[0020] Another technical solution described above has the following advantages or beneficial effects: the connecting column extends along the height of the water receiving pan, with its lower end connected to the bottom wall of the water receiving pan and its upper end extending to below the top opening of the water receiving pan, providing a stable support point for the condenser and enhancing the stability of the condenser installation. Furthermore, the bottom of the condenser extends into the water receiving pan through the top opening, achieving condenser installation within the limited space of the compressor compartment while making reasonable use of the water receiving pan's space, avoiding space waste, and making the overall layout within the compressor compartment more compact.

[0021] In some embodiments of this application, a refrigeration device is provided, wherein the condenser and the centrifugal fan are arranged at intervals to form an interval zone; the refrigeration device further includes a compressor, which is located on one side of the interval zone. When the centrifugal fan is started, the air in the compressor chamber flows through the compressor and then through the interval zone into the air inlet.

[0022] Another technical solution described above has the following advantages or beneficial effects: When the centrifugal fan starts, airflow is formed in the compressor compartment. Part of this airflow flows directly to the condenser, where it undergoes thorough heat exchange, absorbing the heat dissipated by the condenser before flowing to the centrifugal fan. Part of the airflow passes through the compressor, carrying away the heat generated during compressor operation and cooling the compressor. Then, it passes through the gap between the condenser and the centrifugal fan before flowing back to the centrifugal fan. In this way, the cooling fan can effectively dissipate heat from both the condenser and the compressor.

[0023] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising a drain pipe disposed above the water receiving tray and located in the interval area, the drain pipe being used to transport condensate from the refrigeration system and discharge it into the water receiving tray.

[0024] Another technical solution mentioned above has the following advantages or beneficial effects: By placing the drain pipe in the interval area, the idle interval area between the condenser and the centrifugal fan can be fully utilized, making the layout inside the compressor chamber more compact and reasonable, and improving space utilization. Moreover, when the centrifugal fan is working, the air flows through the condenser and then through the water collection pan and drain pipe. Under the suction action of the centrifugal fan, the drain pipe is disturbed, and the air flow efficiency in the water collection pan can be improved, thereby improving the liquid evaporation efficiency in the water collection pan and reducing the temperature of the compressor chamber.

[0025] In some embodiments of this application, a refrigeration device is provided, wherein the ventilation channel is formed by a recess in the back of the housing and the ventilation channel is exposed on the housing.

[0026] Another technical solution described above has the following advantages or beneficial effects: By creating a ventilation channel through a recess in the back of the housing, and simultaneously mounting the condenser on the ventilation channel and exposing it to the housing, the contact area between the housing and the outside air is increased, which facilitates faster heat dissipation into the surrounding environment, thereby improving the condenser's heat dissipation efficiency. Compared to traditional closed or concealed ventilation structures, the ventilation channel exposed in this embodiment can also reduce the number of parts and assembly steps, lower the manufacturing complexity and cost of setting up the ventilation channel, and improve the overall integration and compactness of the refrigeration unit.

[0032] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0033] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0034] like Figure 1As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigerator. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0035] like Figure 1 As shown, in some embodiments, the interior of the housing 1 forms a refrigeration chamber 100 with a front opening. Multiple refrigeration chambers 100 may be provided.

[0036] like Figure 1 As shown, in some embodiments, multiple refrigeration compartments 100 can serve as independent storage spaces, such as freezers, refrigerators, and variable-temperature compartments, to meet different refrigeration needs such as freezing, refrigeration, and variable-temperature storage according to different types of food, and to store items that require refrigeration or freezing. The multiple refrigeration compartments 100 can be arranged vertically or horizontally.

[0037] In some embodiments, the refrigerator may include a liner (not shown in the figure). The liner may be disposed inside the body 11. A cooling compartment 100 may be provided inside the liner. A foamed space is formed between the liner and the body 1. When the foamed material is filled in the foamed space, it can effectively insulate the cooling compartment 100.

[0038] In some embodiments, the refrigerator includes a door 11. The door 11 is disposed on the front side of the refrigerator body 1 and covers the opening of the refrigeration compartment 100 for opening and closing the refrigeration compartment 100.

[0039] It should be noted that multiple doors 11 can be installed. Each door 11 can be installed in a one-to-one correspondence with a refrigeration room 100. Multiple doors 11 can open and close a single refrigeration room 100 simultaneously. A single door 11 can also open and close multiple refrigeration rooms 100 simultaneously.

[0040] In some embodiments, the refrigeration system includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 100.

[0041] Figure 2 for Figure 1 A diagram of the back of the structure.

[0042] like Figure 2 As shown, in some embodiments, the refrigeration system includes a compressor 17. The compressor 17 is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor 17 can deliver the high-temperature, high-pressure refrigerant to the condenser 12.

[0043] Figure 3 for Figure 1A partial schematic diagram. It should be noted that... Figure 3 for Figure 1 A schematic diagram showing the sidewalls hidden.

[0044] like Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration system includes a condenser 12. The condenser 12 can be used to receive refrigerant flowing from the compressor 17, cooling the high-temperature, high-pressure refrigerant gas from the compressor 17 and converting it into a liquid state. The condenser 12 can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0045] In some embodiments, the refrigeration system includes a throttling device (not shown). The condenser 12 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.

[0046] In some embodiments, the refrigeration system includes an evaporator (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator. The evaporator can be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0047] In some embodiments, the compressor 17, condenser 12, throttling device, and evaporator 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.

[0048] like Figure 2 and Figure 3 As shown, in some embodiments, a compressor compartment 101 is provided at the bottom of the housing 1. Part of the refrigeration system may be located in the compressor compartment 101, wherein the compressor 17 is located in the compressor compartment 101.

[0049] like Figure 2 As shown, in some embodiments, a ventilation channel 102 may be provided on the back of the housing 1. The ventilation channel 102 extends along the height direction of the refrigeration unit, with the upper end of the ventilation channel 102 extending to the top of the housing 1 and the lower end of the ventilation channel 102 extending to the top of the compressor chamber.

[0050] Among them, by providing a ventilation channel 102 on the back of the cabinet 1, the ventilation channel 102 can provide heat dissipation space for the condenser 12. When the cabinet 1 is embedded in the cabinet, there is no need to reserve heat dissipation space between the side wall of the cabinet 1 and the cabinet, which greatly saves the installation space of the refrigerator, improves the usable space of the built-in refrigerator, and enables the refrigerator to better integrate into the kitchen and other space environments, meeting the user's needs for space utilization.

[0051] Furthermore, since the air outlet 202 of the cabinet is generally located at the top, by extending the ventilation channel 102 along the height direction of the refrigeration unit, the hot air generated after the air exchanges heat with the condenser 12 can effectively flow upward along the ventilation channel 102 to the air outlet 202 of the top cabinet.

[0052] In some embodiments, the ventilation channel 102 may extend vertically upward along the height direction of the refrigeration device. It should be noted that in some other embodiments, the ventilation channel 102 may also extend upward at an angle, with the upper end of the ventilation channel 102 extending obliquely to the top of the housing 1.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration device may include a centrifugal fan 2. The centrifugal fan 2 is located at the back of the compressor chamber 101, and the air inlet 201 of the centrifugal fan 2 is connected to the compressor chamber 101. The centrifugal fan 2 may be located close to the back of the housing 1. The air outlet 202 of the centrifugal fan 2 is arranged upward, and the air outlet 202 of the centrifugal fan 2 is connected to the lower end of the ventilation channel 102.

[0054] Figure 4 for Figure 3 A magnified view of part A.

[0055] like Figure 4 As shown, in some embodiments, the condenser 12 is located inside the compressor chamber 101 and is positioned opposite the air inlet 201 of the centrifugal fan 2. Thus, the condenser 12 is arranged on the air inlet side of the centrifugal fan 2, allowing airflow to pass fully through it, thereby improving the heat dissipation efficiency of the condenser 12 and reducing the temperature of the compressor chamber 101.

[0056] The centrifugal fan 2 is configured such that when the centrifugal fan 2 is running, the centrifugal fan 2 can draw air from the compressor chamber 101 to form an airflow. The airflow can flow through the condenser 12, then enter the centrifugal fan 2, and then be conveyed upward along the ventilation channel 102 through the air outlet 202 of the centrifugal fan 2.

[0057] Specifically, by installing a centrifugal fan 2 inside the compressor chamber 101 as both a condenser 12 and a heat dissipation fan within the compressor chamber 101, the centrifugal fan 2 can quickly draw air from the compressor chamber 101 to form an airflow, which is then transported upwards along the ventilation channel 102. During this process, because the condenser 12 and the air inlet 201 of the centrifugal fan 2 are positioned opposite each other, the centrifugal fan 2 can directly draw air from the area where the condenser 12 is located. Since the condenser 12 is responsible for cooling the high-temperature, high-pressure gaseous refrigerant into a liquid state during the refrigeration cycle, it releases a large amount of heat, causing the surrounding air temperature to rise. The centrifugal fan 2 directly draws in this high-temperature air and quickly discharges it through forced convection, effectively improving the heat dissipation efficiency of the condenser 12. Furthermore, the airflow in the compressor chamber 101 enters the centrifugal fan 2 along its axial direction and is then transported upwards along the ventilation channel 102. Thus, by utilizing the centrifugal fan 2 to change the airflow direction within the compressor chamber 101, the airflow formed within the compressor chamber 101 can flow upwards efficiently. Compared to the existing technology that uses axial flow fans for heat dissipation, the centrifugal fan 2 can effectively utilize the limited space within the compressor chamber 101 to dissipate heat from the condenser 12 installed in the ventilation channel 102. Moreover, the airflow in the compressor chamber 101 is accelerated by the centrifugal fan 2 before entering the ventilation channel 102, effectively preventing disordered diffusion and mixing of airflow within the housing 1, thereby improving ventilation efficiency. Simultaneously, combined with the lighter weight of hot air and the air pressure from the centrifugal fan 2, the hot air will accelerate upward diffusion, creating an effective circulation path between the compressor chamber 101 and the ventilation channel 102 containing the condenser 12.

[0058] Furthermore, the outlet 202 of the centrifugal fan 2 is connected to the lower end of the ventilation channel 102, ensuring that the dimensions of the outlet 202 and the lower end of the ventilation channel 102 are compatible. This creates a smooth and continuous transition between the centrifugal fan 2 and the lower end of the ventilation channel 102, preventing sudden changes in airflow velocity upon entering the ventilation channel 102, which could lead to a decrease or even stagnation of some airflow and affect overall airflow circulation. The connection between the outlet 202 of the centrifugal fan 2 and the lower end of the ventilation channel 102 effectively reduces energy loss caused by airflow turbulence and eddies, allowing the airflow at the outlet of the centrifugal fan 2 to flow upwards stably and efficiently along the ventilation channel 102, thus improving airflow delivery efficiency.

[0059] Currently, in the market, the ventilation structure of the compressor compartment 101 is usually designed on the side wall or back of the cabinet 1. When the refrigerator is embedded in the cabinet, a certain amount of heat dissipation space usually needs to be reserved, which results in a loss of the refrigerator's volume and a reduction in the usable space of the embedded refrigerator.

[0060] In this embodiment, the ventilation channel 102 is designed on the back of the cabinet 1 and extends along the height direction of the refrigeration unit, with its upper end extending to the top of the cabinet 1. The centrifugal fan 2 delivers air from the compressor chamber 101 upwards to the ventilation channel 102 for heat dissipation. On the one hand, by placing the condenser 12 on the ventilation channel 102, the ventilation channel 102 can serve as a heat dissipation space for the compressor chamber 101. When the refrigeration unit is embedded in the cabinet, there is no need to reserve additional heat dissipation space like traditional built-in refrigerators. The embedded refrigeration unit of this solution can make full use of the cabinet space, increase the effective volume of the refrigerator, allow users to place more items, and improve the volume utilization rate of the refrigerator. On the other hand, because the centrifugal fan 2 has excellent centralized airflow performance, when the centrifugal fan 2 is running, it can quickly draw air from the compressor chamber 101 to form an airflow. Since the condenser 12 is positioned opposite the air inlet 201 of the centrifugal fan 2, the airflow can flow through the condenser 12 and carry away the heat from the surface of the condenser 12 before entering the air inlet 201. After leaving through the air outlet 202 of the centrifugal fan 2, it is transported upward along the ventilation channel 102. This allows the air in the compressor chamber 101 to be efficiently drawn out, forming a good air circulation and effectively reducing the temperature inside the compressor chamber 101. Moreover, the centrifugal fan 2 is smaller in size than the axial fan, which can save space in the compressor chamber 101 and is beneficial for a compact spatial arrangement of the compressor chamber 101.

[0061] Figure 5 for Figure 1 A cross-sectional view; Figure 6 for Figure 1 The bottom diagram.

[0062] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the bottom of the compressor chamber 101 is provided with a heat dissipation air inlet 103, which can communicate with the outside of the compressor chamber 101. Specifically, the bottom of the cabinet is generally provided with a connecting channel, which connects the heat dissipation air inlet 103 to the outside. When the fan is running, air outside the refrigeration unit can enter the compressor chamber 101 through the heat dissipation air inlet 103.

[0063] The air inlet 201 is positioned facing the heat dissipation air inlet 103, wherein the heat dissipation air inlet 103 may be located at the bottom front side of the air inlet 201, and the condenser 12 is located between the heat dissipation air inlet 103 and the air inlet 201 of the centrifugal fan 2.

[0064] By positioning the condenser 12 between the heat dissipation air inlet 103 and the air inlet 201 of the centrifugal fan 2, outside air can directly enter the compressor chamber 101 through the heat dissipation air inlet 103, and first flow through the condenser 12 before flowing into the centrifugal fan 2. Compared to placing the condenser 12 at the air outlet 202 of the centrifugal fan 2, this reduces the efficiency loss caused by the airflow first passing through the compressor chamber 101 and carrying away some heat before cooling the condenser 12. When the air outside the compressor chamber 101 flows through the condenser 12, it can fully absorb the heat released by the condenser 12, thereby reducing the temperature of the condenser 12. The centrifugal fan 2 can efficiently extract the air heated by the condenser 12, forming a continuous airflow circulation, enhancing the heat dissipation effect of the condenser 12, and improving the cooling performance of the refrigeration unit.

[0065] like Figure 5 As shown, in some embodiments, the heat dissipation air inlet 103 is located at the bottom front side of the compressor chamber 101. The centrifugal fan 2 has an air inlet 201 at its front and an air outlet 202 at its top. The top of the centrifugal fan 2 is correspondingly connected to the lower end of the ventilation channel 102. Specifically, the top of the centrifugal fan 2 is inserted into the lower end of the ventilation channel 102, and the air outlet 202 can extend into the ventilation channel 102.

[0066] The front side of the centrifugal fan 2 can refer to the side of the centrifugal fan 2 facing the door 11. Since the air outlet 202 of the centrifugal fan 2 is directly connected to the lower end of the ventilation channel 102, the airflow in the compressor chamber 101 can enter the ventilation channel 102 at a higher speed and pressure after being pressurized by the centrifugal fan 2.

[0067] Furthermore, the condensers 12 are spaced apart in front of the air inlet 201. This maintains a certain distance between the condensers 12 and the air inlet 201 of the centrifugal fan 2. This spacing between the condensers 12 and the air inlet 201 allows airflow to pass more fully across the front and rear sides of the condensers 12, thereby enhancing convective heat transfer. Moreover, airflow from other locations within the compressor chamber 101 can also enter the centrifugal fan 2 through the gap between the condensers 12 and the air inlet 201, further improving the overall ventilation performance of the compressor chamber 101 and thus enhancing the heat dissipation effect on the condensers 12 and the interior of the compressor chamber 101.

[0068] In this embodiment, by providing an air inlet 201 at the front of the centrifugal fan 2 and an air outlet 202 at the top connected to the lower end of the ventilation channel 102, the centrifugal fan 2's ability to change airflow direction by 90 degrees creates a directional airflow path between the compressor chamber 101 and the ventilation channel 102. Specifically, air is drawn in from the front of the centrifugal fan 2, flows through the condenser 12, and then enters the centrifugal fan 2 along its axial direction. After being accelerated by the centrifugal fan 2, it is discharged upwards from the top and directly into the ventilation channel 102. The directional airflow created by the centrifugal fan 2 reduces disordered diffusion and mixing of airflow within the housing 1, reduces airflow resistance, and allows for smoother airflow, thereby improving ventilation efficiency.

[0069] It should be noted that in some other embodiments, an air inlet 201 may be provided on the periphery of the centrifugal fan 2. For example, the air inlet 201 may be located on the left, right or other peripheral positions of the centrifugal fan 2.

[0070] like Figure 4 and Figure 5 As shown, in some embodiments, the condenser 12 and the centrifugal fan 2 are spaced apart to form a gap 105, which connects the compressor compartment 101 and the air inlet 201. The compressor 17 can be located on one side of the gap 105, specifically on one side laterally. When the centrifugal fan 2 starts, the air in the compressor compartment 101 flows through the compressor 17 and then through the gap 105 into the air inlet 201.

[0071] Specifically, when the centrifugal fan 2 starts, airflow is formed within the compressor chamber 101. Part of this airflow flows directly to the condenser 12, where it undergoes thorough heat exchange, absorbing the heat dissipated by the condenser 12 before flowing to the centrifugal fan 2. Part of the airflow passes through the compressor 17, carrying away the heat generated during its operation and cooling the compressor 17. Then, it passes through the partition 105 between the condenser 12 and the centrifugal fan 2 before flowing back to the centrifugal fan 2. In this way, the cooling fan can effectively dissipate heat from both the condenser 12 and the compressor 17. Furthermore, the airflow passing through the compressor 17 flows directly to the centrifugal fan 2 via the partition 105, reducing the increased wind resistance and noise caused by passing through the condenser 12 again, and improving airflow efficiency. The airflow is then transported upwards through the ventilation channel 102 and leaves the compressor chamber 101, further enhancing the overall heat dissipation efficiency of the compressor chamber 101.

[0072] In some embodiments, the bottom wall of the compressor compartment 101 may be provided with ventilation holes (not shown in the figure), which can communicate with the outside through a cabinet. The ventilation holes can be located near the compressor 17. This can increase the ventilation performance of the compressor compartment 101. When the centrifugal fan 2 is started, air from outside the refrigeration unit can enter the compressor compartment 101, flow through the compressor, and then flow through the partition 105 into the centrifugal fan 2. Compared with the airflow path of air flowing through the condenser 12 and then through the compressor 17, this can effectively improve the heat dissipation effect on the compressor.

[0073] like Figure 4 and Figure 5 As shown, in some embodiments, a water collection tray 3 may be provided at the bottom of the compressor chamber 101. The water collection tray 3 can collect the condensate generated during the refrigeration process, prevent the condensate from accumulating in the refrigeration chamber 100, avoid problems such as equipment short circuits and corrosion caused by water accumulation, and ensure the safe operation of the refrigeration device.

[0074] In some embodiments, the heat dissipation air inlet 103 can be located at the bottom front side of the water receiving pan 3, allowing air outside the compressor chamber 101 to flow into the centrifugal fan 2 through the top of the water receiving pan 3. When the heat dissipation fan is started, the airflow passing through the top of the water receiving pan 3 not only increases the evaporation of condensate but also cools the airflow to a certain extent.

[0075] Figure 7 for Figure 4 A connection diagram of the intermediate water tray, condenser and cooling fan; Figure 8 for Figure 7 A schematic diagram from another perspective.

[0076] like Figure 7 and Figure 8 As shown, the centrifugal fan 2 can be positioned above the water collection tray 3, with its bottom supported on the rear side of the water collection tray 3. The upper end of the centrifugal fan 2 can be fixedly connected to the side wall of the ventilation duct 102. The condenser 12 can be positioned above the water collection tray 3, with its bottom supported on the front side of the water collection tray 3.

[0077] The compressor compartment 101 has a water collection tray 3 at its bottom, with the centrifugal fan 2 and condenser 12 positioned behind it. The water collection tray 3 provides a mounting base for the condenser 12 and centrifugal fan 2, and possesses sufficient structural strength to support the weight of components such as the centrifugal fan 2 and condenser 12. Furthermore, the centrifugal fan 2 and condenser 12 are integrated and arranged above the water collection tray 3, forming a compact layout that makes fuller use of the space in the compressor compartment 101. This saves space in the refrigeration system installation and layout, thereby increasing the internal volume of the refrigerator.

[0078] Furthermore, the heat dissipation air inlet 103 is located at the bottom front of the water receiving tray 3. When the centrifugal fan 2 starts, it will form a negative pressure in the compressor chamber 101. The external cold air will naturally enter from the heat dissipation air inlet 103 and flow through the condenser 12. In this process, it will absorb the heat emitted by the condenser 12. Then, under the action of the centrifugal fan 2, the airflow will continue to flow upward and enter the air inlet 201 of the centrifugal fan 2. Then, it will be blown from the air outlet 202 of the centrifugal fan 2 to the ventilation channel 102 and discharged, which will have a good heat dissipation effect on the compressor chamber 101 and the condenser 12.

[0079] like Figure 5 As shown, in some embodiments, the condenser tube 121 of the condenser 12 can be partially disposed within the water receiving pan 3 and fixed to the bottom of the water receiving pan 3. In this way, the condensate in the water receiving pan 3 can directly dissipate heat to the condenser tube of the condenser 12, further improving the heat dissipation efficiency of the condenser 12.

[0080] In some other embodiments, the bottom of the centrifugal fan 2 is supported on the bottom of the compressor chamber 101. The water receiving tray 3 may also be supported on the bottom of the compressor chamber 101.

[0081] like Figure 5 and Figure 8 As shown, in some embodiments, the refrigeration device may include a drain pipe 5. The drain pipe 5 is located above the drip tray 3 and at the interval 105, and is used to transport condensate from the refrigeration system into the drip tray 3. One end of the drain pipe 5 may be connected to the refrigeration chamber 100, allowing condensate in the refrigeration chamber 100 to be discharged into the drip tray 3 via the drain pipe 5. Alternatively, the drain pipe 5 may receive condensate formed at the evaporator and discharge it into the drip tray 3 via the drain pipe 5.

[0082] By placing the drain pipe 5 in the interval 105, the unused interval 105 between the condenser 12 and the centrifugal fan 2 can be fully utilized, making the layout within the compressor chamber 101 more compact and rational, and improving space utilization. Moreover, when the centrifugal fan 2 is working, the air flows through the condenser 12 and then through the water tray 3 and drain pipe 5. Under the suction effect of the centrifugal fan 2, the drain pipe 5 is disturbed, and the airflow efficiency within the water tray 3 is improved, thereby increasing the liquid evaporation efficiency within the water tray 3 and reducing the temperature of the compressor chamber 101.

[0083] Figure 9 for Figure 7 An exploded view; Figure 10 for Figure 9 A schematic diagram showing the connection between the intermediate condenser and the mounting bracket.

[0084] like Figure 9 and Figure 10As shown, in some embodiments, the refrigeration device may include a mounting bracket 4, with the condenser 12 penetrating the rear wall of the mounting bracket 4. The mounting bracket 4 may be arranged around the condenser 12, and is used to fix the condenser 12 to the drip tray 3. The condenser 12 penetrating the rear wall of the mounting bracket 4 allows it to be more directly exposed to the airflow path. When the centrifugal fan 2 starts, air enters the ventilation channel 104 from the heat dissipation inlet 103 and flows through the condenser 12, allowing for more thorough heat exchange between the air and the condenser 12.

[0085] like Figure 5 As shown, a ventilation channel 104 is formed between the mounting bracket and the front wall of the compressor compartment 101. The ventilation channel 104 is connected to the compressor compartment, and the heat dissipation air inlet 103 is located at the bottom of the ventilation channel 104 and is connected to the ventilation channel 104. When the centrifugal fan 2 starts, the air outside the compressor compartment 101 enters the ventilation channel 104 through the heat dissipation air inlet 103, flows through the condenser 12, and then flows to the air inlet 201.

[0086] The ventilation channel 104 formed by the mounting bracket and the front wall of the compressor chamber 101 can limit the airflow space, thereby providing a relatively concentrated and smooth channel for the airflow entering the compressor chamber 101 through the heat dissipation air inlet 103. Under the action of the centrifugal fan 2, when the air flows in the channel, it can more comprehensively cover the surface of the condenser 12, enhance the convective heat transfer effect between the air and the condenser 12, and thus more effectively improve the heat dissipation of the condenser 12.

[0087] like Figure 9 and Figure 10 As shown, in some embodiments, the mounting bracket 4 may include a connecting wall 41, which is disposed on the top of the condenser 12. The top of the connecting wall 41 may abut against the top of the compressor compartment 101, thereby preventing the airflow entering the compressor compartment 101 through the heat dissipation air inlet 103 from flowing to the centrifugal fan 2 through the gap between the connecting wall 41 and the side wall of the compressor compartment 101.

[0088] The mounting bracket 4 may include a first mounting wall 42. The first mounting wall 42 is connected to one end of the connecting wall 41 and extends downward from one end of the connecting wall 41. The first mounting wall 42 is located on one side of the condenser 12. The side of the first mounting wall 42 away from the condenser 12 can abut against one side wall of the compressor compartment 101, thereby preventing airflow entering the compressor compartment 101 through the heat dissipation air inlet 103 from flowing to the centrifugal fan 2 through the gap between the first mounting wall 42 and the side wall of the compressor compartment 101.

[0089] Mounting bracket 4 may include a second mounting wall 43. The second mounting wall 43 is connected to the other end of the connecting wall 41 and extends downward from the other end of the connecting wall 41. The second mounting wall 43 is located on the other side of the condenser 12. The second mounting wall 43 and the first mounting wall 42 are arranged at intervals and respectively on the left and right sides of the condenser 12. The first mounting wall 42 and the second mounting wall 43 are located on both sides of the condenser 12 and extend downward, further fixing the condenser 12 from the side. The connecting wall 41, the first mounting wall 42, and the second mounting wall 43 can together form a frame-like support structure, thereby surrounding the condenser 12 and enhancing the stability of the condenser 12 installation.

[0090] The second mounting wall 43 extends forward on the side away from the connecting wall 41. The front side of the second mounting wall 43 can abut against the front wall of the compressor chamber 101. The connecting wall 41, the first mounting wall 42, the second mounting wall 43 and the front wall of the compressor chamber 101 form a ventilation channel 104.

[0091] Since the heat dissipation air inlet 103 is formed on the bottom front side of the water receiving tray 3, the front side of the water receiving tray 3 is spaced apart from the front wall of the compressor chamber 101. By extending the second mounting wall forward away from the connecting wall 41, the front side of the second mounting wall can abut against the front wall of the compressor chamber 101, thus forming a ventilation channel 104 together with the connecting wall 41, the first mounting wall 42, and the front wall of the compressor chamber 101. In this way, the structure of the mounting frame 4 can define the ventilation channel 104 within the space of the compressor chamber 101, which can guide the air to flow more smoothly. The airflow entering the compressor chamber 101 from the heat dissipation air inlet 103 can flow more orderly along the ventilation channel 104, passing through the condenser 12 and the centrifugal fan 2 in sequence, reducing turbulence and resistance during the airflow process, improving the efficiency of airflow, and thus enhancing the heat dissipation effect of the condenser 12.

[0092] In some embodiments, the mounting bracket 4 may include a support base plate 44. The support base plate 44 may be disposed at the bottom of the condenser 12 and connected to the water receiving tray 3. The support base is disposed between the water receiving tray 3 and the condenser 12, and can provide support and protection for the bottom of the condenser 12.

[0093] like Figure 4 and Figure 5 As shown, in some embodiments, the condenser 12 can be arranged in the water receiving pan 3, thereby improving the compactness of the space arrangement in the compressor chamber 101. Moreover, the condensate in the water receiving pan 3 keeps the surrounding area at a relatively low temperature, which can exchange heat with the condenser 12 and thus improve the heat dissipation efficiency of the condenser 12.

[0094] like Figure 4 , Figure 5 and Figure 9 As shown, in some embodiments, a connecting column 31 may be provided inside the water receiving tray 3. The connecting column 31 may extend along the height direction of the water receiving tray 3, with the lower end of the connecting column 31 connected to the bottom wall of the water receiving tray 3, the upper end of the connecting column 31 extending upward, and the upper end of the connecting column 31 being spaced apart below the top opening of the water receiving tray 3.

[0095] The bottom of the condenser 12 is connected to the upper end of the connecting column 31, and the bottom of the condenser 12 extends into the water receiving pan 3 through the top opening of the water receiving pan 3. Specifically, the upper end of the connecting column 31 can form a support surface, and the bottom of the condenser 12 can be supported on the support surface of the connecting column 31, so that the condenser 12 can be spaced above the bottom of the water receiving pan 3.

[0096] Specifically, the connecting column 31 extends along the height of the water receiving pan 3, with its lower end connected to the bottom wall of the water receiving pan 3 and its upper end extending below the top opening of the water receiving pan 3, providing a stable support point for the condenser 12. The bottom of the condenser 12 is connected to the upper end of the connecting column 31, allowing the weight of the condenser 12 to be effectively transferred to the water receiving pan 3, enhancing the stability of the condenser 12 installation. Moreover, the bottom of the condenser 12 extends into the water receiving pan 3 through the top opening, achieving both the installation of the condenser 12 and the rational use of the space in the water receiving pan 3 within the limited space of the compressor chamber 101, avoiding space waste and making the overall layout within the compressor chamber 101 more compact. Furthermore, the condensate in the water receiving pan 3 absorbs heat during evaporation, thereby lowering the ambient temperature. The condenser 12 extending into the water receiving pan 3 allows it to be in a relatively low-temperature environment, which is beneficial for heat dissipation. The heat on the surface of the condenser 12 can be transferred to the surrounding air more quickly, and the heat absorbed by the evaporation of the condensate in the water tray 3 can also further remove some of the heat, thus enhancing the heat dissipation effect of the condenser 12.

[0097] like Figure 10 As shown, in some embodiments, the connecting column 31 is provided with a connecting hole, and the support base plate 44 may also be provided with a connecting hole. The connecting hole of the connecting column 31 and the connecting hole of the support base plate 44 can be set correspondingly, so that the connecting piece can pass through and be locked, so that the condenser 12 can be stably supported on the top of the connecting column 31.

[0098] In some embodiments, the connecting posts 31 may be provided in two or more, thereby increasing the number of support connection points at the bottom of the condenser 12 and thus improving the installation stability of the condenser 12.

[0099] like Figure 2As shown, in some embodiments, the back of the housing 1 can be recessed to form a ventilation channel 102, which is exposed on the housing 1. By creating the ventilation channel 102 in the recess on the back of the housing 1, and simultaneously mounting the condenser 12 on the ventilation channel 102 and exposing it to the housing 1, the contact area between the housing 1 and the outside air is increased, which facilitates faster heat dissipation into the surrounding environment, thereby improving the heat dissipation efficiency of the condenser 12. Compared to traditional closed or concealed ventilation structures, the ventilation channel 102 exposed on the housing 1 in this embodiment can also reduce the number of parts and assembly steps, lower the manufacturing complexity and cost of setting the ventilation channel 102, and improve the overall integration and compactness of the refrigeration device.

[0100] It should be noted that in some other embodiments, the ventilation channel 102 may be formed inside the housing 1. The opening of the ventilation channel 102 exposed outside the housing 1 may be covered by a side panel (not shown in the figure), which shields the ventilation channel 102.

[0101] like Figure 2 As shown, in some embodiments, the housing 1 may include a back panel 13 and a first side panel 14 and a second side panel 15 disposed opposite to each other. The back panel 13 is located at the back of the refrigeration unit, and the first side panel 14 and the second side panel 15 are respectively disposed on both sides of the back panel 13. The first side panel 14 and the second side panel 15 may be disposed on opposite left and right sides of the back panel 13.

[0102] Figure 11 for Figure 2 A schematic diagram of the central ventilation component.

[0103] like Figure 11 As shown, the cabinet 1 may be equipped with a ventilation component 16. The ventilation component 16 is located at the back of the cabinet 1, and is arranged adjacent to and spaced apart from the back panel 13. The ventilation component 16 extends along the height direction of the refrigeration compartment 100. The ventilation component 16 may be recessed to form a ventilation channel 102. One side of the ventilation component 16 is connected to the back panel 13, and the other side of the ventilation component 16 is connected to the second side panel 15.

[0104] The ventilation channel 102 is formed by the recess of the ventilation component 16. The operator can directly install the ventilation component 16 on the back of the box 1, so that the box 1 is pre-equipped with the heat dissipation channel of the compressor chamber 101, which simplifies the structure and installation structure of the ventilation duct.

[0105] like Figure 2As shown, both the ventilation component 16 and the back panel 13 are located on the back of the housing 1. One side of the back panel 13 is connected to the rear end of the first side panel 14, and the other side of the back panel 13 is connected to one side of the ventilation component 16. The other side of the ventilation component 16 is connected to the rear end of the second side panel 15. In this way, the ventilation component 16 only occupies part of the space on the back of the housing 1, which can reduce the space occupied by the internal space of the refrigeration unit, save space reserved for heat dissipation channels in the refrigeration unit, and help improve the space compactness of the refrigeration unit.

[0106] like Figure 11 As shown, in some embodiments, the ventilation component 16 may include a main board 161, which may be disposed on the back of the refrigeration device. The main board 161 is arranged parallel to the back panel 13 and is located on the front side of the back panel 13. The main board 161 extends along the height direction of the refrigeration device.

[0107] The ventilation component 16 may include a first side plate 162, which may be bent and extended rearward from the side of the main board 161 near the back panel 13, and the first side plate 162 is connected to the back panel 13.

[0108] The ventilation component 16 may include a second side panel 163, which extends rearward from the main board 161 near the second box side panel 15. The second side panel 163 is disposed at a relatively interval on the side of the first side panel 162 away from the box back panel 13, and is connected to the second side wall. A ventilation channel 102 is formed between the main board 161, the first box side panel 14, and the second box side panel 15.

[0109] like Figure 11 As shown, in some embodiments, the ventilation element 16 may be U-shaped.

[0110] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
