Description

Technical Field

[0001] The utility model relates to the field of refrigeration, and specifically to a freezer. Background Art

[0002] In today's life, as an important device for storing food and other items that need to be stored at low temperature, freezers are widely used in industries such as food, medicine, and chemical industry. In order to achieve better refrigeration effects, current freezers on the market have compressors and condensers set at the lower end of the freezer, and evaporators and cold air outlets for absorbing heat inside the freezer are set at the upper end of the freezer. Utilizing the principle that cold air has a greater density, cold air flows from the upper end to the lower end of the freezer, making the refrigeration effect inside the freezer more uniform, and thus achieving a better refrigeration effect.

[0003] Adopting the above design requires a return air pipe to connect the evaporator at the upper end of the freezer and the condenser at the lower end of the freezer, as well as a drain pipe for discharging the condensed water generated by the evaporator. Generally speaking, both the evaporator and the drain pipe need to be installed inside the freezer to play their respective roles. For the convenience of installation, the return air pipe and the drain pipe also need to be separately installed inside the freezer. At this time, it is necessary to add a shielding member to shield or wrap the return air pipe and the drain pipe to achieve the beautification effect. The increase in accessories will increase the production cost of the freezer, resulting in a relatively high production cost and a more cumbersome production process for the freezer. Therefore, it is necessary to develop a freezer to optimize the structure and production process of the freezer and reduce the production cost of the freezer. Summary of the Utility Model

[0004] In view of the problem that the production process of the existing freezer in the above-mentioned prior art is relatively cumbersome, resulting in a relatively high production cost, the technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A freezer, comprising a cabinet body. The cabinet body includes an inner box, the inner box is provided with a card slot, and the cabinet body further includes a water pipe cover connected to the card slot. One side of the water pipe cover is provided with a drainage channel and a return air channel, and the water pipe cover is integrally formed.

[0006] Further, the card slot is recessed in the opening direction away from the inner box, and a plurality of protrusions are evenly and symmetrically arranged on both sides of the card slot.

[0007] Further, one side of the water pipe cover is provided with an extension part that abuts against the card slot. The extension part is provided with a first groove, and the first groove abuts against the protrusion to fix the water pipe cover to the card slot. The width of the extension part is less than or equal to the depth of the card slot.

[0008] Further, there are at least two extension parts which are symmetrically arranged. The extension parts are provided with second grooves, and the depression direction of the second grooves is opposite to that of the first grooves. One end of the extension part far from the card slot is arc-shaped.

[0009] Further, the drainage channel is arranged between the two extension parts, the air return channel is located on one side of the drainage channel, and the diameter width of the drainage channel is less than or equal to the width of the extension part.

[0010] Further, the cabinet body further includes an evaporator assembly arranged at the upper end of the inner box and a return air pipe connected to the evaporator assembly. A drainage groove is arranged at the lower end of the inner box, and a drainage hole and a convex platform are arranged in the drainage groove. The convex platform is provided with a return air pipe hole.

[0011] Further, the position of the drainage hole corresponds to the position of the drainage channel, and the position of the return air pipe hole corresponds to the position of the air return channel.

[0026] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0027] Please refer to Figures 1 to 9 , a freezer, including a cabinet body 1, the cabinet body 1 includes an inner box 3, the inner box 3 is provided with a card slot 31, the cabinet body 1 further includes a water pipe cover 4 connected to the card slot 31, one side of the water pipe cover 4 is provided with a drainage channel 41 and a return air channel 43, and the water pipe cover 4 is integrally formed. The design of the card slot 31 enables the water pipe cover 4 to be stably and detachably fixed on the inner box 3. By providing the drainage channel 41 and the return air channel 43 on one side of the water pipe cover 4, the water pipe cover 4, the drainage channel 41 and the return air channel 43 are integrally formed into a whole. While the water pipe cover 4 plays a shielding role, it reduces the installation steps in the prior art when the drain pipe and the return air pipe are assembled separately, solves the problem that multiple shielding parts need to be installed in the prior art to shield or wrap the return air pipe, resulting in high production costs, cumbersome production processes and low production efficiency of the freezer, effectively optimizes the structure of the freezer, improves the production efficiency of the freezer and reduces the production cost.

[0028] Furthermore, there is a freezer, wherein the card slot 31 is recessed in a direction away from the opening of the inner box 3, and a plurality of protrusions 311 are evenly and symmetrically arranged on both sides of the card slot 31. The card slot 31 being recessed in a direction away from the opening of the inner box 3 makes the space inside the inner box 3 more regular. If the card slot 31 is recessed in the direction of the opening of the inner box 3, the card slot 31 will protrude from the inside of the inner box 3, making the space inside the inner box 3 irregular and not conducive to the utilization of the space of the inner box 3. And the plurality of protrusions 311 on both sides of the card slot 31 can play a role in fixing the water pipe cover 4, preventing it from loosening or falling off during use, and effectively improving the connection stability between the card slot 31 and the water pipe cover 4.

[0029] Furthermore, there is a freezer, wherein one side of the water pipe cover 4 is provided with an extension part 42 that abuts against the card slot 31. The extension part 42 is provided with a first groove 421, and the first groove 421 abuts against the protrusion 311 to fix the water pipe cover 4 to the card slot 31. The width of the extension part 42 is less than or equal to the depth of the card slot 31. Figure 7 In this case, L is the width of the extension part 42. The first groove 421 on the extension part 42 abuts against the protrusions 311 on both sides of the card slot 31. Adopting such a design can ensure that the water pipe cover 4 can be accurately positioned and firmly fixed in the card slot 31 during installation. The protrusion 311 and the first groove 421 form a stable locking mechanism with each other, effectively preventing the water pipe cover 4 from shifting or falling off during the use of the freezer, and improving the reliability and stability of the freezer structure. Further, due to the design of the extension part 42, when the water pipe cover 4 is installed in place, a closer contact is formed between its edge and the card slot 31. This close contact can effectively reduce the entry of impurities such as water vapor and dust into the card slot 31, thereby improving the sealing performance of the freezer.

[0030] Further, a freezer, wherein there are at least two extension parts 42 which are symmetrically arranged. The extension parts 42 are provided with second grooves 422, and the depression direction of the second grooves 422 is opposite to that of the first grooves 421. One end of the extension part 42 away from the clamping groove 31 is arc-shaped. With such a design, the connection stability between the water pipe cover 4 and the clamping groove 31 can be significantly enhanced. The symmetric extension parts 42 can make the forces received by the water pipe cover 4 evenly distributed, preventing deformation or loosening due to uneven stress. Further, the design of the second grooves 422 can optimize the structural strength of the extension parts 42, disperse the stress received by the extension parts 42 during installation, and prevent damage to the extension parts 42 caused by stress concentration. At the same time, the arc-shaped design of one end of the extension part 42 away from the clamping groove 31 can effectively reduce the friction and collision between the extension part 42 and the protrusion 311 during installation and disassembly, making the disassembly and installation of the water pipe cover 4 smoother, effectively improving the user experience and the service life of the water pipe cover 4.

[0031] Further, a freezer, wherein the drainage channel 41 is arranged between the two extension parts 42, the return air channel 43 is located on one side of the drainage channel 41, and the diameter width of the drainage channel 41 is less than or equal to the width of the extension part 42. The drainage channel 41 is arranged between the two extension parts 42. With such a design, the space of the water pipe cover 4 can be fully utilized, and at the same time, the drainage structure can be combined with the water pipe cover 4, reducing the components of the freezer, effectively improving the production efficiency of the freezer and reducing the production cost. At the same time, the return air channel 43 is located on one side of the drainage channel 41, effectively avoiding direct interference between the two channels. And the diameter width of the drainage channel 41 is less than or equal to the width of the extension part 42, enabling the water pipe cover 4 to be completely embedded in the clamping groove 31, ensuring the compactness and neatness of the internal structure of the freezer.

[0032] Furthermore, a freezer, the cabinet body 1 further includes an evaporator assembly 5 disposed at the upper end of the inner box 3 and a return air pipe 6 connected to the evaporator assembly 5. A drain trough 32 is provided at the lower end of the inner box 3. A drain hole 321 and a boss 322 are provided in the drain trough 32, and a return air pipe hole 33 is provided on the boss 322. The evaporator assembly 5 is mainly used to absorb the heat inside the freezer and reduce the temperature inside the freezer through the evaporation process of the refrigerant. Disposing the evaporator assembly 5 at the upper end of the inner box 3 can effectively utilize the space. At the same time, based on the principle that cold air has a greater density, the cold air generated by the evaporator assembly 5 can naturally flow from the upper end of the inner box 3 to the lower end, so that the internal temperature of the inner box 3 is more uniform, achieving a better refrigeration effect, effectively improving the functionality of the freezer. Further, the return air pipe 6 is connected to the evaporator assembly 5 to convey the evaporated refrigerant gas back to other processing units of the refrigeration system. The design of the drain trough 32 is used to collect the condensed water generated inside the freezer. The drain hole 321 in the drain trough 32 allows the condensed water to be discharged smoothly, preventing water accumulation from damaging the inside of the freezer or causing the food inside the freezer to deteriorate and rot. Further, a boss 322 is provided in the drain trough 32, and a return air pipe hole 33 is provided on the boss 322. With such a design, the return air pipe hole 33 provides a channel for connecting the return air pipe 6 to the components outside the inner box 3, and the design of the boss 322 makes the upper surface of the return air pipe hole 33 higher than the surface of the drain trough 32, ensuring that the condensed water in the drain trough 32 cannot enter the return air pipe hole 33. At the same time, a seal is provided at the connection between the return air pipe 6 and the return air pipe hole 33 to ensure the sealing performance inside the freezer.

[0033] Furthermore, in a freezer, the position of the drain hole 321 corresponds to the position of the drain channel 41, and the position of the return air pipe hole 33 corresponds to the position of the return air channel 43. With such a design, it can be ensured that the condensed water generated inside the freezer can directly and smoothly drain into the drain hole 321 through the drain channel 41, reducing the path length and resistance of the condensed water during the flow process, improving the drainage efficiency, and at the same time avoiding the accumulation of condensed water inside the freezer, reducing the risk of bacterial growth and decreased refrigeration efficiency caused by water accumulation, effectively improving the functionality of the freezer. Similarly, the position of the return air pipe hole 33 corresponds to the position of the return air channel 43, enabling the return air pipe 6 to be accurately and efficiently connected to the return air channel 43. With such a design, not only the pipeline layout is simplified, reducing the energy loss and noise generation during the return air process, but also the installation difficulty of the return air pipe 6 is reduced, effectively improving the production efficiency of the freezer.

[0034] Furthermore, a freezer, the evaporator assembly 5 includes a control panel 51, a fan 52 connected to the control panel 51, and an evaporator 53 disposed behind the fan 52. The control panel 51 includes a water receiving portion 511 located below the evaporator 53, and the fan 52 is inclined. The control panel 51 is used to control the operation of the fan 52 and the evaporator 53. The evaporator 53 is used to absorb the heat in the air. The heat in the air is absorbed through the evaporation process of the refrigerant inside the evaporator 53, thereby achieving the refrigeration effect. The fan 52 disposed in front of the evaporator 53 can accelerate the air flow inside the freezer, enabling the hot air to pass through the evaporator 53 for heat exchange more quickly and become cold air, effectively improving the refrigeration effect of the freezer. At the same time, the inclined setting of the fan 52 can optimize the direction and speed of the air flow, and also play a role in improving the refrigeration effect of the freezer. Furthermore, the control panel 51 further includes a water receiving portion 511 located below the evaporator 53. The evaporator 53 generates condensate during operation, and the water receiving portion 511 can collect this condensate to prevent it from falling on the food in the freezer, effectively improving the practicality of the freezer.

[0035] Furthermore, a freezer, the water receiving portion 511 includes a diversion port 512 disposed above the drainage channel 41. The design of the diversion port 512 can effectively guide the condensate collected by the water receiving portion 511 into the drainage channel 41. By setting the diversion port 512, the condensate can be drained away from the water receiving portion 511 more quickly and smoothly, avoiding the problem of condensate accumulation in the water receiving portion 511. This can not only reduce the risk of bacterial growth but also keep the inside of the freezer dry and clean, thereby improving the hygiene level and service life of the freezer.

[0036] Furthermore, a freezer, the cabinet body 1 further includes a compressor, a condenser, and a capillary tube disposed below the inner box 3. Setting the compressor, condenser, and capillary tube below the inner box 3 is beneficial to optimizing the space utilization of the freezer. At the same time, the compressor, condenser, and capillary tube are important components of the refrigeration cycle system. The compressor is used to compress the refrigerant vapor to increase its pressure and temperature. The condenser cools and liquefies the high-temperature and high-pressure refrigerant vapor through heat exchange with the outside air. The capillary tube is used to reduce the pressure of the refrigerant, converting it from a liquid state to a low-temperature and low-pressure gas-liquid mixture state.

[0037] Working principle: The refrigerant gas at low temperature and low pressure enters the compressor and is compressed into a gas at high temperature and high pressure. Then, the refrigerant gas in the high-temperature and high-pressure state enters the condenser, where it is cooled and liquefied through heat exchange with the outside air, releasing heat. The liquefied refrigerant after condensation passes through the capillary tube, and the pressure drops sharply, and the refrigerant becomes a gas-liquid mixture state at low temperature and low pressure. Finally, the refrigerant at low temperature and low pressure enters the evaporator 53, where it absorbs the heat inside the freezer and evaporates into a gas, thereby reducing the temperature inside the freezer.
