Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator. Background Technology

[0002] A refrigerator is a household appliance that uses refrigeration technology to maintain a low-temperature environment, mainly used to store food and beverages to extend their shelf life.

[0003] In related technologies, a refrigerator includes an outer shell, a refrigerator liner, a refrigeration system, and a mounting bracket. The refrigeration system includes a compressor, a condenser, and a return gas pipe. The condenser and compressor are connected via the return gas pipe. The return gas pipe is located in the area between the back of the refrigerator liner and the back panel of the outer shell, and is fixed to the back of the refrigerator liner by the mounting bracket.

[0004] However, the fixed bracket is prone to rotation during the refrigerator foaming process, which causes the return pipe to come into contact with the back panel of the outer shell, resulting in condensation on the back panel. Utility Model Content

[0005] This application provides a refrigerator with a highly reliable fixing bracket, which makes the refrigerator less prone to condensation.

[0006] This application provides a refrigerator, including:

[0007] The outer casing has a receiving cavity;

[0008] The inner box is located in the receiving cavity, and there is a gap between the outer wall of the inner box and the inner wall of the outer shell.

[0009] A refrigeration system, which includes a compressor and a condenser connected by a return gas pipe;

[0010] A fixed bracket is located within the gap. The first end of the fixed bracket is connected to the outer wall of the chamber, and the second end of the fixed bracket is connected to the inner wall of the outer shell. The first end and the second end are opposite to each other. The fixed bracket is connected to the return air pipe and is configured to fix the return air pipe.

[0011] In this way, the first end of the fixed bracket is connected to the outer wall of the refrigerator liner, and the second end of the fixed bracket is connected to the inner wall of the outer shell. The first end and the second end are opposite each other. The cantilever structure is eliminated, thereby increasing the reliability of the fixed bracket installation. The fixed bracket and the return pipe are less likely to rotate, and the return pipe is less likely to touch the outer shell, thus making the refrigerator less prone to condensation.

[0012] In some embodiments, the first end is bonded to the outer wall of the box liner.

[0013] This makes the connection more convenient and reliable, and the fixed bracket is less likely to rotate.

[0014] In some embodiments, the second end abuts against the inner wall of the outer casing.

[0015] In this way, the friction between the second end and the outer shell is used to prevent the rotation of the fixed bracket, resulting in high installation efficiency.

[0016] In some embodiments, the ratio between the distance from the axis of the return air pipe within the fixed bracket to the first end and the distance from the axis of the return air pipe within the fixed bracket to the second end along the direction from the first end to the second end is greater than 0.8 and less than 1.2.

[0017] When the ratio of the distance from the axis of the return air pipe within the fixed support to its first end to its second end is less than 0.8, the distance between the return air pipe and the liner is small, making it easier for the return air pipe to contact the liner and thus causing condensation. When the ratio of the distance from the axis of the return air pipe within the fixed support to its first end to its second end is greater than 1.2, the distance between the return air pipe and the outer shell is small, making it easier for the return air pipe to contact the outer shell and thus causing condensation.

[0018] In some embodiments, the end face area of ​​the first end is greater than the end face area of ​​the second end.

[0019] In this way, the bonding area between the first end and the inner liner is larger, which helps to improve the stability of the bond and makes it less likely for the fixing bracket to rotate. The end face area of ​​the second end is smaller, allowing for a smaller dimension of the second end of the fixing bracket along the X-axis, and a smaller dimension of the return air pipe within the fixing bracket along the X-axis. In other words, the size of the return air pipe held in place by the fixing bracket can be smaller, resulting in less installation resistance, which facilitates securing the return air pipe within the fixing bracket. It also makes it easier to install the fixing bracket at bends in the return air pipe. Furthermore, the smaller end face area of ​​the second end, whether along the X-axis or the Z-axis, allows for elastic deformation of the fixing bracket under external force, effectively securing the return air pipe within the fixing bracket.

[0020] In some embodiments, the fixing bracket is provided with a fixing structure, the fixing structure including:

[0021] A fixed cavity is provided that runs through the second direction, and the return air pipe is installed inside the fixed cavity;

[0022] An installation cavity is provided through the second direction, located on the side of the fixed cavity away from the inner chamber, and is connected to the fixed cavity and the outside of the second end; along the first direction, the size of the fixed cavity is larger than the size of the installation cavity;

[0023] Wherein, the first direction is perpendicular to the second direction, the first direction is perpendicular to the direction from the first end to the second end, and the second direction is perpendicular to the direction from the first end to the second end.

[0024] In this way, the return air pipe is inserted into the fixed cavity through the installation cavity, and the return air pipe is locked in the fixed cavity, making it difficult for it to fall out of the fixed cavity and enter the installation cavity.

[0025] In some embodiments, the number of fixing structures is at least two, and the fixing cavities in the at least two fixing structures are of different sizes to match the return air pipes of different sizes.

[0026] This improves the versatility of the mounting bracket, meeting the installation requirements of different sizes of return pipes in different refrigerators.

[0027] In some embodiments, the size of the mounting cavity decreases along the first direction from the second end to the first end.

[0028] This makes it easier to install the return air pipe into the fixed cavity along the direction from the second end to the first end during installation. Moreover, after installation, the return air pipe is less likely to enter the installation cavity.

[0029] In some embodiments, the fixing structure includes two deformable cavities, which are disposed through the second direction. The two deformable cavities are located on opposite sides of the mounting cavity along the first direction. The deformable cavities are spaced apart from the mounting cavity, and the side of the deformable cavity facing the first end communicates with the fixing cavity.

[0030] In this way, the side wall of the mounting cavity near the fixed cavity is easy to deform, which makes the dimension of the mounting cavity near the fixed cavity along the first direction smaller, which facilitates the installation of the return air pipe.

[0031] In some embodiments, the size of the deformation cavity increases along the first direction from the second end to the first end.

[0032] In this way, the side wall of the mounting cavity near the fixed cavity is easy to deform, which makes the dimension of the mounting cavity near the fixed cavity along the first direction smaller, thereby reducing the probability of the return air pipe falling off after entering the fixed cavity.

[0049] In related technologies, a refrigerator includes an outer shell, a refrigerator liner, a refrigeration system, and a mounting bracket. The refrigeration system includes a compressor, a condenser, and a return gas pipe. The condenser and compressor are connected via the return gas pipe. The return gas pipe is located in the area between the back of the refrigerator liner and the back panel of the outer shell, and is fixed to the back of the refrigerator liner by the mounting bracket.

[0050] However, one end of the fixed bracket is connected to the liner, forming a cantilever structure. During the refrigerator's foaming process, the fixed bracket is prone to rotation, causing the return pipe to come into contact with the back panel of the outer shell, resulting in condensation on the back panel.

[0051] To solve the aforementioned technical problems, in the refrigerator provided by this application, the first end of the fixing bracket is connected to the outer wall of the refrigerator liner, and the second end of the fixing bracket is connected to the inner wall of the outer shell. The first and second ends are opposite to each other. This eliminates the cantilever structure, thereby increasing the reliability of the fixing bracket installation. The fixing bracket and the return pipe are less likely to rotate, and the return pipe is less likely to touch the outer shell, thus reducing the likelihood of condensation in the refrigerator.

[0052] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0053] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0054] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0055] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0056] This application provides a refrigerator, which can be a frost-free refrigerator or a direct-cooling refrigerator.

[0057] Figure 1 A schematic diagram of the refrigerator structure is provided for an embodiment of this application. Figure 2 This provides a structural schematic diagram of a refrigerator from another angle, illustrating an embodiment of this application.

[0058] See Figure 1 and Figure 2 As shown, the refrigerator provided in this application includes a cabinet 100.

[0059] The housing 100 includes an outer shell 110, a liner 120, and a compressor compartment 130. The outer shell 110 has a receiving cavity with a first and a second access port, which are respectively located on opposite sides of the outer shell 110 along the depth direction (Y-axis). The first access port can be located on the front side of the outer shell 110, and the second access port can be located on the rear side. The compressor compartment 130 is located inside the outer shell 110, and its opening is opposite to the second access port, allowing the placement of compressors and condensers, etc., into the compressor compartment 130 via the second access port and the main opening.

[0060] The liner 120 is located inside the outer shell 110 and forms at least one refrigeration compartment. The liner 120 has a third access port opposite to the first access port, allowing items to be placed into the refrigeration compartment via both the third and first access ports. A gap exists between the outer wall of the liner 120 and the inner wall of the outer shell 110. This gap can be used to install a foam layer and piping.

[0061] A foam layer is filled between the inner chamber 120, the outer shell 110, and the compressor chamber 130. The foam layer is used to insulate the refrigeration chamber, thereby ensuring the refrigeration effect inside the refrigeration chamber.

[0062] There may be at least one refrigeration room. When there is only one refrigeration room, it may be any one of a refrigerator, freezer, or variable temperature room. When there are two or more refrigeration rooms, the multiple refrigeration rooms may include at least one or more of a refrigerator, freezer, or variable temperature room.

[0063] For example, the outer casing 110 may include a first bottom plate 114, a first top plate 113, first side plates 112, and a first back plate 111. The first bottom plate and the first top plate 113 are arranged opposite each other in the length direction (direction shown by the Z-axis) of the casing 100. There are two first side plates 112, which are located on both sides of the first bottom plate and the first top plate 113 and are connected to the first bottom plate and the first top plate 113. The two first side plates 112, the first bottom plate, and the first top plate 113 form a first access port. The first back plate 111 is opposite to the first access port and is connected to the first top plate 113 and the two first side plates 112. The first back plate 111, the two first side plates 112, and the first bottom plate form a second access port.

[0064] In some possible implementations of the embodiments of this application, the first top plate 113 and the two first side plates 112 can be an integral structure. This configuration simplifies the structure of the outer shell 110, improves the production efficiency of the outer shell 110, and facilitates the assembly of the box 100. Exemplarily, the first top plate 113 and the two first side plates 112 can be formed by bending the same sheet material.

[0065] The press chamber 130 may include a second bottom plate, a second top plate, a second back plate, and two second side plates. The second bottom plate abuts against the first bottom plate of the outer casing 110 to form the bottom surface of the housing 100. The second top plate and the second bottom plate are opposite each other along the length direction (Z-axis direction) of the housing 100. The two second side plates are located on both sides of the second bottom plate and the second top plate, and the second side plates connect the second bottom plate and the second top plate. The two second side plates, together with the second bottom plate and the second top plate, form an opening. The second back plate is flush with the first back plate 111 to cover the opening.

[0066] In some possible implementations of this application, the second top plate and the first bottom plate of the outer casing can be an integral structure. This configuration simplifies the structure of the press chamber 130, facilitates refrigerator assembly, and improves refrigerator production efficiency. Exemplarily, the second top plate and the first bottom plate can be formed by bending the same sheet material.

[0067] In some embodiments, the refrigerator includes a door that is rotatably connected to the cabinet body. The door rotates relative to the cabinet body, thereby opening or closing the cooling compartment.

[0068] In some embodiments, the refrigerator includes a refrigeration system. The refrigeration system may include a compressor, a condenser, a throttling device, and an evaporator, which are connected in series via piping through which refrigerant flows. The compressor and condenser may be housed within a compressor compartment 130, and the evaporator within a cabinet liner 120.

[0069] When the compressor is working, low-temperature, low-pressure refrigerant is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas in the compressor cylinder before being discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, its temperature continuously decreasing until it is gradually cooled into room-temperature, high-pressure saturated vapor, and further cooled into a saturated liquid. The pressure of the refrigerant remains almost constant throughout the condensation process. The throttling device may include a pressure-reducing pipe or an electronic expansion valve. This application describes the throttling device as including a pressure-reducing pipe, as pressure-reducing pipes are low in cost and less prone to malfunction. After condensation, the saturated refrigerant liquid undergoes throttling and pressure reduction through the pressure-reducing pipe, transforming the refrigerant into room-temperature, low-pressure wet vapor. Subsequently, this room-temperature, low-pressure wet vapor absorbs heat and vaporizes through the evaporator, lowering not only the temperature of the evaporator and its surroundings but also transforming the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air inside the refrigeration chamber, thereby lowering the temperature of the air inside the cold source cavity. The refrigerant that comes out of the evaporator returns to the compressor, repeating the above process so that the evaporator can continuously cool the air in the cold source chamber, thereby maintaining the storage compartment at the set temperature.

[0070] The compressor and condenser are connected via a return pipe 200. Because the refrigerant temperature inside the return pipe 200 is low, condensation easily forms on the inner wall of the outer casing 110 when the return pipe 200 contacts it. Condensation easily forms on the outer wall of the casing 120 when the return pipe 200 contacts it.

[0071] Figure 3 This is a schematic diagram of the structure of the rear panel, liner, vent pipe, and fixing bracket of the refrigerator provided in the embodiments of this application. Figure 4 for Figure 3 A magnified view of a portion of point A in the middle.

[0072] See Figure 3 and Figure 4 As shown, in some embodiments, the refrigerator includes a mounting bracket 300. The mounting bracket 300 is used to fix the return vent pipe 200, thereby creating a gap between the return vent pipe 200 and the outer casing 110 and the inner liner 120.

[0073] The fixing bracket 300 is located within the gap between the outer wall of the inner box 120 and the inner wall of the outer shell 110. Specifically, the fixing bracket 300 can be located between the back of the inner box 120 and the first rear back panel 111. Alternatively, the fixing bracket 300 can be located between the side of the inner box 120 and the first side panel 112. The following description uses the example of the fixing bracket 300 being located between the back of the inner box 120 and the first rear back panel 111.

[0074] The first end 310 of the fixed bracket 300 is connected to the outer wall of the box liner 120, and the second end 320 of the fixed bracket 300 is connected to the inner wall of the outer shell 110. The first end 310 and the second end 320 are opposite to each other.

[0075] The fixed bracket 300 is connected to the return pipe 200, and the fixed bracket 300 is configured to fix the return pipe 200. In this way, the cantilever structure is eliminated, thereby increasing the reliability of the installation of the fixed bracket 300. The fixed bracket 300 and the return pipe 200 are not easy to rotate, and the return pipe 200 is not easy to touch the outer shell 110, thus making the refrigerator less prone to condensation.

[0076] In some embodiments, the fixing bracket 300 may be made of PP (Polypropylene).

[0077] In some embodiments, the first end 310 is bonded to the outer wall of the box liner 120. This provides greater ease of connection and higher reliability.

[0078] In some embodiments, the first end 310 is connected to the outer wall of the box liner 120 by fasteners such as screws or rivets.

[0079] In some embodiments, the second end 320 abuts against the inner wall of the outer casing 110. In this way, the friction between the second end 320 and the outer casing 110 prevents the rotation of the fixing bracket 300, resulting in higher installation efficiency.

[0080] In some embodiments, the second end 320 is bonded to the inner wall of the housing 110. This provides greater ease of connection and higher reliability.

[0081] Figure 5 This is a schematic diagram of the structure of the fixed bracket and return pipe in the refrigerator provided in the embodiment of this application. Figure 6 for Figure 5 A magnified view of a section at point B in the middle.

[0082] See Figure 5 and Figure 6 As shown, in some embodiments, the ratio between the distance a from the axis of the return air pipe 200 located in the fixed bracket 300 to the first end 310 and the distance b from the axis of the return air pipe 200 located in the fixed bracket 300 to the second end 320 along the direction from the first end 310 to the second end 320 is greater than 0.8 and less than 1.2.

[0083] When the ratio between the distance a from the axis of the return air pipe 200 located in the fixed bracket 300 to the first end 310 and the distance b from the axis of the return air pipe 200 located in the fixed bracket 300 to the second end 320 is less than 0.8, the distance a between the return air pipe 200 and the liner 120 is small, and the return air pipe 200 is more likely to come into contact with the liner 120, thus making it easier for condensation to form on the liner 120.

[0084] When the ratio between the distance a from the axis of the return air pipe 200 located in the fixed bracket 300 to the first end 310 and the distance b from the axis of the return air pipe 200 located in the fixed bracket 300 to the second end 320 is greater than 1.2, the distance b from the axis of the return air pipe 200 located in the fixed bracket 300 to the second end 320 is smaller, and the return air pipe 200 is more likely to come into contact with the outer shell 110, thereby making the outer shell 110 more likely to condense.

[0085] Specifically, the direction from the first end 310 to the second end 320 is the direction shown by the Y-axis. The axis of the return air pipe 200 located within the fixed bracket 300 extends in the direction shown by the X-axis. Alternatively, the axis of the return air pipe 200 located within the fixed bracket 300 extends in the direction shown by the Z-axis. This article will use the example of the return air pipe 200 located within the fixed bracket 300 having its axis extended in the direction shown by the X-axis as an example.

[0086] It should be noted that when the axis of the return air pipe 200 located inside the fixed bracket 300 is tilted, the center of the circle located at the center of the return air pipe 200 inside the fixed bracket 300 can be taken to obtain the distance from the center to the first end 310 and the distance from the center to the second end 320.

[0087] For example, along the direction from the first end 310 to the second end 320, the ratio between the distance a from the axis of the return air pipe 200 located in the fixed bracket 300 to the first end 310 and the distance b from the axis of the return air pipe 200 located in the fixed bracket 300 to the second end 320 can be 0.9, 1.1 or 1.2.

[0088] In some embodiments, the ratio of the distance 'a' from the axis of the return air pipe 200 located within the fixed bracket 300 to the first end 310 along the direction from the first end 310 to the second end 320 to the distance 'b' from the axis of the return air pipe 200 located within the fixed bracket 300 to the second end 320 is 1. This ensures that the position of the return air pipe 200 is relatively balanced between the first end 310 and the second end 320.

[0089] In some embodiments, along the direction from the first end 310 to the second end 320, the distance from the axis of the return air pipe 200 located within the fixed bracket 300 to the first end 310 is 23 mm. The distance from the axis of the return air pipe 200 located within the fixed bracket 300 to the second end 320 is 19.5 mm. The ratio between the two is 1.18.

[0090] It should be noted that the specific values ​​of the distance from the axis of the return pipe 200 located in the fixed bracket 300 to the first end 310, and the distance from the axis of the return pipe 200 located in the fixed bracket 300 to the second end 320, along the direction from the first end 310 to the second end 320, can be set according to the needs of the refrigerator size. This embodiment does not make specific limitations here.

[0091] Figure 7 This is a schematic diagram of the structure of the fixed bracket in the refrigerator provided in an embodiment of this application. Figure 8 for Figure 7 Top view, Figure 9 for Figure 7 The bottom view, Figure 10 for Figure 7 Side view.

[0092] See Figures 7 to 10 As shown, in some embodiments, the end face area of ​​the first end 310 is greater than the end face area of ​​the second end 320.

[0093] The end face area of ​​the first end 310 is the projected area toward the planes shown by the X and Z axes. The end face area of ​​the second end 320 is the projected area toward the planes shown by the X and Z axes.

[0094] Understandably, the end face area of ​​the first end 310 is larger than that of the second end 320. This results in a larger bonding area between the first end 310 and the inner liner 120, which improves the stability of the bond. Conversely, the end face area of ​​the second end 320 is smaller. Therefore, the size of the second end 320 of the fixing bracket 300 along the X-axis can be smaller, and the size of the return air pipe 200 within the fixing bracket 300 along the X-axis can also be smaller. In other words, the size of the return air pipe 200 that is engaged with the fixing bracket 300 can be smaller, resulting in less installation resistance, which facilitates the engagement of the return air pipe 200 within the fixing bracket 300. Furthermore, it allows for the installation of the fixing bracket 300 at bends in the return air pipe 200 for engagement. Furthermore, the smaller end face area of ​​the second end 320, the smaller size of the second end 320 of the fixed bracket 300 along the X-axis direction, or the smaller size of the second end 320 of the fixed bracket 300 along the Z-axis direction, are all conducive to the elastic deformation of the fixed bracket 300 under the action of external force, so as to clamp the return air pipe 200 inside the fixed bracket 300.

[0095] In some embodiments, the ratio of the end face area of ​​the first end 310 to the end face area of ​​the second end 320 is greater than 2.

[0096] When the ratio of the end face area of ​​the first end 310 to the end face area of ​​the second end 320 is less than 2, the end face area of ​​the first end 310 is small, and the bonding area between the first end 310 and the box liner 120 is small, which is not conducive to improving the stability of the bonding.

[0097] For example, the ratio of the end face area of ​​the first end 310 to the end face area of ​​the second end 320 is 3, 4, 5, 6, 7 or 8, etc.

[0098] For example, the end face area of ​​the first end 310 is 700 square millimeters. The end face area of ​​the second end 320 is 170 square millimeters. The ratio of the end face area of ​​the first end 310 to the end face area of ​​the second end 320 is 4.12.

[0099] Figure 11 for Figure 7 The main view. Figure 12 This is a structural schematic diagram of the fixed bracket in the refrigerator provided in an embodiment of this application from another angle.

[0100] See Figure 11 and Figure 12 As shown, in some embodiments, the mounting bracket 300 is provided with a fixing structure 330. The fixing structure 330 is used to fix the return air pipe 200.

[0101] The fixed structure 330 includes a fixed cavity 331 that extends through the second direction, and the return air pipe 200 is fitted inside the fixed cavity 331.

[0102] It should be noted that the second direction can be either the direction indicated by the Z-axis or the direction indicated by the X-axis. This article will use the direction indicated by the X-axis as the second direction for explanation.

[0103] The fixing structure 330 includes a mounting cavity 332 that extends through the second direction.

[0104] The mounting cavity 332 is located on the side of the fixed cavity 331 away from the box liner 120. The mounting cavity 332 is connected to the fixed cavity 331 and is connected to the outside of the second end 320.

[0105] Along the first direction, the size of the fixed cavity 331 is larger than the size of the mounting cavity 332. The first direction can be the direction shown by the Z-axis. In this way, the return air pipe 200 is inserted into the fixed cavity 331 through the mounting cavity 332, and the return air pipe 200 is locked in the fixed cavity 331, making it difficult for it to fall out of the fixed cavity 331 and enter the mounting cavity 332.

[0106] Wherein, the first direction is perpendicular to the second direction, the first direction is perpendicular to the direction from the first end 310 to the second end 320, and the second direction is perpendicular to the direction from the first end 310 to the second end 320. The first direction is the direction shown by the Z-axis, the second direction is the direction shown by the X-axis, and the direction from the first end 310 to the second end 320 is the direction shown by the Y-axis.

[0107] When installing the return air pipe 200, insert the return air pipe 200 into the fixing cavity 331 through the mounting cavity 332 along the direction shown by the Y axis. The return air pipe 200 is then locked in the fixing cavity 331, thereby fixing the return air pipe 200.

[0108] In some embodiments, the number of fixing structures 330 is at least two, and the fixing cavities 331 in the at least two fixing structures 330 are of different sizes. This improves the versatility of the fixing bracket 300 and meets the installation requirements of different sizes of return air pipes 200 in different refrigerators.

[0109] For example, there can be two fixing structures 330. One fixing structure 330 is used to install a return air pipe 200 with a radius of 2.5 mm. The other is used to install a return air pipe 200 with a radius of 4 mm.

[0110] In some embodiments, the size of the mounting cavity 332 decreases along the first direction from the second end 320 to the first end 310. This facilitates the installation of the return air pipe 200 into the fixing cavity 331 along the direction from the second end 320 to the first end 310 during installation. Moreover, after installation, the return air pipe 200 is less likely to enter the mounting cavity 332.

[0111] Specifically, the first direction is the direction indicated by the Z-axis, the direction from the first end 310 to the second end 320 is the direction indicated by the Y-axis, and the direction from the second end 320 to the first end 310 is the negative direction indicated by the Y-axis.

[0112] In some embodiments, the fixing structure 330 includes two deformable cavities 333. The deformable cavities 333 are disposed through the second direction. The two deformable cavities 333 are located on opposite sides of the mounting cavity 332 along the first direction, and the deformable cavities 333 and the mounting cavity 332 are spaced apart. The side of the deformable cavity 333 facing the first end 310 communicates with the fixing cavity 331.

[0113] Understandably, the deformation cavities 333 facilitate the elastic deformation of the fixed bracket 300, thereby increasing the size of the mounting cavity 332 and facilitating the installation of the return air pipe 200. Furthermore, the two deformation cavities 333 are located on opposite sides of the mounting cavity 332 along the first direction, with the side of the deformation cavity 333 facing the first end 310 communicating with the fixed cavity 331. This allows the sidewall of the mounting cavity 332 near the fixed cavity 331 to deform easily, facilitating the installation of the return air pipe 200. Moreover, by providing the deformation cavities 333, the dimension of the mounting cavity 332 near the fixed cavity 331 along the first direction can be smaller, thus reducing the probability of the return air pipe 200 falling out after entering the fixed cavity 331.

[0114] In some embodiments, the dimension of the deformation cavity 333 along the first direction increases from the second end 320 to the first end 310. This makes the sidewall of the mounting cavity 332 near the fixed cavity 331 easier to deform, facilitating the installation of the return air pipe 200. It also allows the dimension of the mounting cavity 332 near the fixed cavity 331 along the first direction to be smaller, thereby reducing the probability of the return air pipe 200 falling out after entering the fixed cavity 331.

[0115] See Figure 7 and Figure 12 As shown, to reduce material costs and the weight of the fixed bracket 300, a weight-reducing structure 340 is provided on the fixed bracket 300. The weight-reducing structure 340 can be located at both ends of the fixed bracket 300 along the second direction. In this way, the arrangement of the weight-reducing structure 340 will not easily affect the connection between the fixed bracket 300 and the outer shell 110 and the inner box 120. The second direction is the direction shown by the X-axis.

[0116] Specifically, the weight-reducing structure 340 can be a weight-reducing hole or a weight-reducing groove.

[0117] In some embodiments, the number of weight-reducing structures 340 is multiple, and the multiple weight-reducing structures 340 are arranged at intervals.

[0118] In some embodiments, the fixing bracket 300 may be manufactured by injection molding.
