Description

Technical Field

[0001] This utility model relates to the field of freezing and preservation technology, and more specifically, to a freezer. Background Technology

[0002] A freezer is a device used for refrigerating and storing goods. A freezer integrates both the evaporator and condenser into a single unit.

[0003] Traditional freezers integrate refrigeration system components such as fans and condensers at the top or bottom of the freezer, which takes up a lot of space, reduces the freezer's volume, and also causes problems such as inconvenient installation.

[0004] In summary, the volume of freezers in the current technology is relatively small. Utility Model Content

[0005] This utility model provides a freezer to solve the problem of small volume in existing freezers.

[0006] To achieve the above objectives, this utility model provides a freezer, including a cabinet and a refrigeration system. The devices in the refrigeration system are all located on the back of the cabinet and are arranged along the vertical direction of the freezer.

[0007] Furthermore, the refrigeration system includes an evaporator, a compressor, a throttle valve, and a condenser connected by refrigerant piping.

[0008] Furthermore, the rear area of ​​the cabinet includes a cooling space and a heat dissipation space, which are separated by a heat insulation board;

[0009] The evaporator is located within the refrigeration space; the compressor, the throttle valve, and the condenser are disposed in the heat dissipation space; the evaporator, compressor, throttle valve, and condenser are arranged vertically as a whole.

[0010] Furthermore, the evaporator is located above the heat dissipation space, which is located at the bottom of the cabinet.

[0011] Furthermore, the cabinet includes a storage chamber for placing items or food, with a cooling air outlet at the top of the storage chamber and a cooling air return vent on the side wall of the storage chamber. The cooling air outlet is connected to the cooling space, and the cooling air return vent is also connected to the cooling space.

[0012] Furthermore, a cooling fan is provided in the cooling space, which blows cold air towards the cooling air outlet, and the airflow of the receiving chamber flows back to the cooling space through the cooling return air outlet.

[0013] Furthermore, the cabinet has a heat dissipation air inlet on the side wall corresponding to the heat dissipation space, and the heat dissipation air inlet is connected to the heat dissipation space;

[0014] The cabinet has a heat dissipation vent on its bottom wall corresponding to the heat dissipation space, and the heat dissipation vent is connected to the heat dissipation space.

[0015] A cooling fan is installed in the heat dissipation space. The cooling fan is located between the heat dissipation outlet and the condenser. The cooling fan is used to blow the airflow entering through the heat dissipation inlet out through the heat dissipation outlet.

[0016] Furthermore, within the heat dissipation space, the throttle, the compressor, the condenser, the cooling fan, and the heat dissipation outlet are arranged from top to bottom along the vertical direction of the cabinet.

[0017] Furthermore, the heat insulation plate extends to the back, top, and bottom of the cabinet, and the heat dissipation space is located on the side of the heat insulation plate facing outward.

[0018] Furthermore, the insulation board is a foam board, the throttling device is a capillary tube, and part of the refrigerant pipes in the refrigeration system are routed through the foam board.

[0019] Traditional freezers place the compressor, condenser, fan, and other refrigeration systems at the top or bottom, occupying a significant amount of space. They also require a piping system to connect them, often dedicating the entire upper or lower section of the freezer to these components, thus greatly reducing the freezer's volume. This new freezer, however, arranges the refrigeration system components vertically at the back of the cabinet, significantly reducing the space occupied by the refrigeration system. The vertical piping also makes more efficient use of space. Although the height required to house these components increases in this back-mounted freezer, it still significantly reduces the volume occupied by these components, providing a larger overall freezer volume and effectively increasing the freezer's capacity. Attached Figure Description

[0020] Figure 1 This is a front view of the freezer according to an embodiment of the present utility model;

[0021] Figure 2 yes Figure 1 AA cross-sectional view of the freezer. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] See Figure 1 and Figure 2As shown, according to an embodiment of the present invention, a freezer is provided. The freezer includes a cabinet body 10 and a refrigeration system. The devices in the refrigeration system are all disposed on the back of the cabinet body 10, and the devices in the refrigeration system are arranged along the vertical direction of the freezer.

[0024] Traditional freezers place the compressor, condenser, fan, and other refrigeration systems at the top or bottom, occupying a significant amount of space. They also require a piping system to connect them, often dedicating the entire upper or lower section of the freezer to these components, thus greatly reducing the freezer's volume. This new freezer, however, arranges the refrigeration system components vertically at the back of the cabinet, significantly reducing the space occupied by the refrigeration system. The vertical piping also makes more efficient use of space. Although the height required to house these components increases in this back-mounted freezer, it still significantly reduces the volume occupied by these components, providing a larger overall freezer volume and effectively increasing the freezer's capacity.

[0025] Preferably, the refrigeration system includes an evaporator 21, a compressor 22, a throttle valve 23, and a condenser 24 connected by refrigerant pipelines.

[0026] The evaporator 21, compressor 22, throttle 23 and condenser 24 mentioned above are key components of the refrigeration system. Arranging the evaporator 21, compressor 22, throttle 23 and condenser 24 in a vertical direction can make full use of the width and thickness of each device and minimize the space occupied by the evaporator 21, compressor 22, throttle 23 and condenser 24.

[0027] See Figure 2 The back area of ​​the cabinet 10 includes a cooling space 11 and a heat dissipation space 12, which are separated by a heat insulation plate 30.

[0028] The evaporator 21 is located in the refrigeration space 11; the compressor 22, the throttle 23 and the condenser 24 are arranged in the heat dissipation space 12; the evaporator 21, the compressor 22, the throttle 23 and the condenser 24 are arranged vertically as a whole.

[0029] Dividing the rear area into a cooling space 11 and a heat dissipation space 12 prevents the evaporator and condenser from affecting each other's temperature, avoiding the problem of reduced cooling efficiency due to the refrigeration system being concentrated in the rear area of ​​the cabinet. By placing the evaporator separately in the cooling space, the cooling efficiency and temperature of the freezer are effectively guaranteed. The arrangement of the cooling space 11, the heat dissipation space 12, and the various devices in the refrigeration system makes full use of the rear space of the cabinet.

[0030] Preferably, the evaporator 21 is located above the heat dissipation space 12, and the heat dissipation space 12 is located at the bottom of the cabinet 10.

[0031] The heat dissipation space 12 is located at the bottom of the cabinet, which is conducive to the blowing out of hot air. There are many cooling components inside the heat dissipation space 12. Placing the heat dissipation space at a low position also makes it easy to inspect and maintain, making it more convenient for staff to perform maintenance.

[0032] Combination Figure 2 As shown, the cabinet 10 includes a storage chamber 13 for placing items or food. A cooling air outlet 41 is provided on the top of the storage chamber 13, and a cooling air return outlet 42 is provided on the side wall of the storage chamber 13. The cooling air outlet 41 is connected to the cooling space 11, and the cooling air return outlet 42 is connected to the cooling space 11.

[0033] The airflow direction in the receiving cavity 13 of the cabinet 10 is shown in the figure. Figure 2 As indicated by the arrow, the recirculating airflow in the receiving cavity 13 enters the cooling space 11 through the cooling return air inlet 42. After heat exchange and cooling, the cold air is distributed to various areas from the top of the receiving cavity 13 through the cooling air outlet 41. The cooling air outlet 41 is located at the top to utilize the physical property of cold air sinking, which can comprehensively and efficiently cool all areas of the receiving cavity, resulting in better cooling effect.

[0034] To further improve the cooling and heat exchange efficiency, a cooling fan 25 is installed in the cooling space 11. The cooling fan 25 blows cold air towards the cooling air outlet 41, and the airflow in the receiving chamber 13 flows back to the cooling space 11 through the cooling return air outlet 42.

[0035] The cooling fan 25 can direct the airflow entering from the bottom cooling return air inlet 42 to the top cooling air outlet 41, increasing airflow and improving cooling efficiency.

[0036] In this embodiment, the cabinet 10 has a heat dissipation air inlet 51 on the side wall corresponding to the heat dissipation space 12, and the heat dissipation air inlet 51 is connected to the heat dissipation space 12.

[0037] The cabinet 10 is provided with a heat dissipation vent 52 on the bottom wall corresponding to the heat dissipation space 12, and the heat dissipation vent 52 is connected to the heat dissipation space 12.

[0038] A cooling fan 26 is provided in the heat dissipation space 12. The cooling fan 26 is located between the heat dissipation outlet 52 and the condenser 24. The cooling fan 26 is used to blow the airflow entering through the heat dissipation inlet 51 out through the heat dissipation outlet 52.

[0039] See Figure 2The combination of the heat dissipation air inlet 51, the heat dissipation air outlet 52, and the heat dissipation fan 26 can quickly expel the heat generated by the compressor and the high temperature heat of the condenser from the heat dissipation space, increasing the operating efficiency of the refrigeration system and ensuring the safety of the device.

[0040] Preferably, within the heat dissipation space 12, the throttle 23, the compressor 22, the condenser 24, the heat dissipation fan 26, and the heat dissipation outlet 52 are arranged from top to bottom along the vertical direction of the cabinet 10.

[0041] The airflow passes sequentially through the throttle 23, the compressor 22, and the condenser 24, rapidly carrying away heat from these three structures and ensuring normal heat exchange. Furthermore, the throttle 23, compressor 22, condenser 24, and cooling fan 26 are arranged vertically, saving space. The structure of this embodiment, by placing the refrigeration system at the back of the cabinet, also solves the problem of difficult airflow in back-mounted freezers, ensuring smooth airflow and good cooling performance.

[0042] Preferably, the heat insulation plate 30 extends to the back, top and bottom of the cabinet 10, and the heat dissipation space 12 is located on the side of the heat insulation plate 30 facing outward.

[0043] In other words, all components of the heat dissipation space 12 are separated from the other structures of the cabinet by heat insulation boards (foam boards) to prevent a decrease in cooling effect, ensure that the cooling capacity is not wasted, and achieve high efficiency and energy saving.

[0044] In this embodiment, the heat insulation board 30 is a foam board, the throttling device 23 is a capillary tube, and part of the refrigerant pipes in the refrigeration system are arranged through the foam board.

[0045] The structure using foamed boards and capillary tubes is simple, has high assembly efficiency, is easy to maintain, and has low cost.

[0046] Once the freezer and refrigeration system start operating, the compressor pressurizes the refrigerant in the back-mounted freezer into a high-temperature, high-pressure gas. This high-temperature, high-pressure gaseous refrigerant then enters the condenser through pipes. Simultaneously, the cooling fan continuously draws in room-temperature air from the air inlet. The high-temperature, high-pressure gaseous refrigerant exchanges heat with the room-temperature air through the condenser, transforming into a high-temperature, high-pressure liquid refrigerant. The heated air is then exhausted from the back-mounted freezer through the air outlet by the cooling fan.

[0047] After the high-temperature, high-pressure liquid refrigerant enters the capillary tube, the rapid change in tube diameter causes it to release a large amount of pressure and cool down quickly as it flows out of the capillary tube, becoming a low-temperature, low-pressure liquid refrigerant that flows into the evaporator. At this time, the refrigeration fan operates, drawing a large amount of air from inside the back-mounted freezer through the refrigeration return air vent into the evaporator where it exchanges heat with the low-temperature, low-pressure liquid refrigerant. After heat exchange, the low-temperature, low-pressure liquid refrigerant absorbs heat, becomes gaseous, and re-enters the compressor for circulation. The air, having cooled, is then driven by the refrigeration fan through the air duct into the freezer's cavity, thus achieving the cooling effect.
