Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, and in particular to a compressor chamber and a refrigerator. Background Technology

[0002] The refrigerator's body includes the casing and the compressor compartment. The compressor compartment is mounted on the bottom plate of the casing, forming a mounting cavity with an opening on one side. The compressor and main control box are typically housed and installed within this mounting cavity. Because the compressor compartment is usually manufactured using a one-piece stamping process, it is difficult to construct a complex mounting structure. Therefore, it is usually constructed by stamping multiple mounting holes into the side wall of the compressor compartment. The edge of the main control box has multiple mounting lugs, which are screwed onto the mounting holes.

[0003] Because the main control box is suspended on the side wall of the compressor chamber, workers need to hold the main control box with one hand to keep it in the predetermined position while using the other hand to hold a tool (such as an electric screwdriver) to tighten multiple screws into the mounting holes. It can be seen that this assembly method is inconvenient and inefficient. Utility Model Content

[0004] The main purpose of this invention is to propose a compressor compartment and a refrigerator, which aims to improve the assembly efficiency between the main control box and the compressor compartment.

[0005] To achieve the above objectives, the present invention proposes a compressor compartment for use in a refrigerator, wherein the main control box of the refrigerator is installed in the compressor compartment, and the compressor compartment includes: A first bulkhead and two second bulkheads are respectively located on both sides of the first bulkhead.

[0006] In one embodiment, one of the second bulkheads is made of plastic and is provided with the first snap-fit ​​portion and the first mounting portion.

[0007] In one embodiment, both second bulkheads are made of plastic.

[0008] In one embodiment, the first bulkhead is made of metal.

[0009] In one embodiment, the first snap-fit ​​portion is configured as a snap-fit ​​groove extending along a first direction, one end of the first snap-fit ​​portion penetrates the end edge of the opening and forms a snap-fit ​​inlet communicating with the opening, and the second snap-fit ​​portion is configured as a snap-fit ​​protrusion and can be snapped into the first snap-fit ​​portion along the first direction through the snap-fit ​​inlet.

[0010] In one embodiment, in the first direction, the two opposite slot sidewalls of the first snap-fit ​​portion are arranged close to each other.

[0011] In one embodiment, the first snap-fit ​​portion has limiting ribs extending from the two slot edges in the second direction. The second snap-fit ​​portion includes a first protrusion and two second protrusions. The first protrusion is disposed on the outer side of the main control box. The two second protrusions are disposed on opposite sides of the first protrusion along the second direction and are spaced apart from the outer side of the main control box. The second protrusion has a limiting end face close to the outer surface of the main control box. The limiting end face abuts against the inner side of the limiting rib. The second direction intersects with the first direction.

[0012] In one embodiment, the first protrusion is provided with two first guide surfaces that are opposite each other in the second direction, and the two first guide surfaces are arranged close to each other in the first direction.

[0013] In one embodiment, the first protrusion is provided with two first guide surfaces opposite each other in the second direction, and the first guide surfaces have an included angle α with the first direction, the included angle α satisfying: 2°≤α≤5°.

[0014] In one embodiment, the second protrusion has a second guide surface on the side away from the first protrusion, and the two second guide surfaces are arranged close to each other in the first direction.

[0015] In one embodiment, the second protrusion has a second guide surface on the side away from the first protrusion, and the second guide surface has an angle β with the first direction, the angle β satisfying: 2°≤β≤5°.

[0016] In one embodiment, the distance between the two limiting ribs is gradually reduced in the first direction.

[0017] In one embodiment, the limiting end face has an angle θ with the first direction, and the angle θ satisfies: 1°≤θ≤3°.

[0018] In one embodiment, the first mounting portion is configured as a mounting hole provided at the end edge of the opening, and the second mounting portion is configured as a mounting through hole, wherein the mounting through hole is fastened to the mounting hole by a screw.

[0019] In one embodiment, the number of the first mounting parts is configured to be one.

[0020] In one embodiment, the second latching portion is configured as a latching protrusion, and the main control box is also provided with a mounting lug. The second mounting portion is disposed on the mounting lug, and the mounting lug and the second latching portion protrude from the same outer side surface of the main control box.

[0023] This utility model also proposes a refrigerator, including a main control box and the aforementioned compressor compartment.

[0024] The technical solution of this utility model achieves the pre-fixation function of the main control box through the snap-fit ​​cooperation of the first snap-fit ​​part and the second snap-fit ​​part. During the assembly process, the worker can first snap the second snap-fit ​​part of the main control box with the first snap-fit ​​part on the first bulkhead, so that the main control box can be stably fixed in the predetermined installation position without manual support, thereby freeing the worker's hands and allowing them to focus on completing the subsequent screw tightening work. In this way, compared with the inconvenience caused by the main control box being suspended in the air in traditional assembly methods, requiring one hand to support and the other to operate tools, this solution reduces the operational difficulty of workers during assembly, greatly improves the convenience and efficiency of assembly, and thus improves the assembly efficiency in the refrigerator production process. At the same time, the introduction of the snap-fit ​​structure helps to improve the installation accuracy of the main control box, reduces assembly errors caused by positional misalignment, and further enhances the consistency and reliability of product assembly.

[0032] This utility model proposes a compressor chamber.

[0033] Please see Figures 1 to 3 In one embodiment of this utility model, the compressor compartment 100 is applied to a refrigerator. The main control box 200 of the refrigerator is installed in the compressor compartment 100. The compressor compartment 100 includes a first compartment wall 110 and two second compartment walls 120. The two second compartment walls 120 are respectively disposed on both sides of the first compartment wall 110. The first compartment wall 110 and the second compartment wall 120 are together covered on the bottom plate of the cabinet 300 and together with the bottom plate enclose an installation cavity 130 with an opening 131 on one side. At least one second compartment wall 120 is provided with a first snap-fit ​​part 121 and a first mounting part 122. The main control box 200 is provided with a second snap-fit ​​part 210 and a second mounting part 220. The first snap-fit ​​part 121 is used for the second snap-fit ​​part 210 to snap-fit ​​to achieve pre-fixation. The second mounting part 220 is connected to the first mounting part 122 by fasteners.

[0034] Specifically, the compressor compartment 100 is located at the bottom of the refrigerator unit. It covers the bottom plate of the refrigerator body 300, forming an open-sided mounting cavity 130. The mounting cavity 130 primarily houses the compressor, main control box 200, and other related components, centrally encapsulating these key components to prevent dust and foreign objects from entering. The compressor compartment 100 reduces the direct transmission of operating noise, providing some sound insulation. Simultaneously, it provides a mounting platform for the compressor and main control box 200, bearing the vibration and weight of the compressor during operation. The main control box 200 is the refrigerator's electronic control module, installed inside the compressor compartment 100. It is generally positioned close to the compressor but at a certain distance to avoid being affected by the high temperatures generated during compressor operation. The main control box 200 receives signals from temperature sensors, door switches, and button panels, and controls the compressor's start / stop, fan operation, defrost cycle, and frequency conversion according to preset programs.

[0035] The compressor chamber 100 includes a first chamber wall 110 and two second chamber walls 120. The two second chamber walls 120 are distributed along a third direction on opposite sides of the first chamber wall 110 and together with the first chamber wall 110 form the overall frame of the compressor chamber 100. At least one second chamber wall 120 is provided with a first snap-fit ​​portion 121 and a first mounting portion 122. The first snap-fit ​​portion 121 may be a slot, a flexible snap-fit ​​seat, or other structure, for quick engagement with corresponding components on the main control box 200. The first mounting portion 122 may be a screw hole or a through hole, for subsequent final fixing with screws. The main control box 200 is provided with a second snap-fit ​​portion 210 and a second mounting portion 220. The second snap-fit ​​portion 210 may be a hook, a boss, a flexible snap-fit ​​foot, or other structure, which can cooperate with the first snap-fit ​​portion 121 on the compressor chamber 100 to complete the snap-fit. The second mounting portion 220 may be a mounting through hole, for alignment with the first mounting portion 122 and locking with fasteners (such as screws).

[0036] When assembling the main control box 200, first align the main control box 200 with the snap-fit ​​position on the press chamber 100, and push it so that its second snap-fit ​​part 210 snaps into the first snap-fit ​​part 121, thereby achieving quick pre-fixing between the main control box 200 and the press chamber 100; at this time, the main control box 200 is stably supported by the first snap-fit ​​part 121, and no hand support is required. The worker can then free up both hands and use tools to pass the fasteners through the second mounting part 220 of the main control box 200 and tighten them onto the first mounting part 122 of the press chamber 100 to complete the final secure fixing.

[0037] Compared to the traditional assembly method that relies entirely on screws for suspension and requires one hand to hold the box while the other hand tightens the screws, the technical solution of this utility model achieves automatic pre-positioning and self-holding of the main control box 200 through snap-fit, freeing up the workers' hands so that they only need to focus on tightening the screws. This reduces the difficulty of operation during assembly, greatly shortens the operation time, improves the assembly efficiency between the main control box 200 and the press chamber 100, and increases the production line cycle time. It also reduces problems such as stripped screws and improper installation caused by hand tremors and fatigue, improving assembly consistency and reliability.

[0038] Furthermore, through the cooperation of the first snap-fit ​​part 121 and the second snap-fit ​​part 210, the main control box 200 can be quickly pre-fixed during installation, maintaining a stable position without manual support. This reliable positioning provides a foundation for subsequent automated operations, facilitating the use of automatic screw-driving equipment for fastening, thereby further improving the assembly efficiency between the main control box 200 and the press chamber 100, and contributing to the improvement of the automation level of the production line.

[0039] In addition, the dual fixing method of the main control box 200 and the compressor chamber 100, which is locked by a combination of snap-fit ​​and screw, is more stable than the traditional method of simply relying on screw connection. Especially in the case of transportation or operation vibration environment, it can effectively prevent loosening. Moreover, the engagement relationship between the first snap-fit ​​part 121 and the second snap-fit ​​part 210 can also bear some stress, reduce the force on the screw, and extend the service life.

[0040] The technical solution of this utility model achieves the pre-fixation function of the main control box 200 through the snap-fit ​​cooperation between the first snap-fit ​​part 121 and the second snap-fit ​​part 210. During the assembly process, the worker can first snap-fit ​​the second snap-fit ​​part 210 of the main control box 200 with the first snap-fit ​​part 121 on the first bulkhead 110, so that the main control box 200 can be stably fixed in the predetermined installation position without manual support, thereby freeing the worker's hands and allowing them to focus on completing the subsequent screw tightening work. In this way, compared with the inconvenience caused by the main control box 200 being suspended in the air in the traditional assembly method, requiring one hand to support and the other to operate tools, this solution reduces the operational difficulty of workers during assembly, greatly improves the convenience and efficiency of assembly, and thus improves the assembly efficiency in the refrigerator production process. At the same time, the introduction of the snap-fit ​​structure helps to improve the installation accuracy of the main control box 200, reduces assembly errors caused by positional deviation, and further enhances the consistency and reliability of product assembly.

[0041] In one implementation, please refer to Figure 9 One of the second bulkheads 120 is made of plastic and has a first snap-fit ​​part 121 and a first mounting part 122.

[0042] Traditional press chambers 100 are typically formed by integral stamping of metal sheets, but this makes it difficult to manufacture complex structures, especially for directly forming delicate snap-fit ​​structures. This solution uses plastic for one of the second chamber walls 120 of the press chamber 100, and integrates a first snap-fit ​​part 121 (such as a slot or elastic buckle seat) and a first mounting part 122 (such as a threaded post or mounting through hole) onto this plastic second chamber wall 120. This transforms the second chamber wall 120 from a traditional metal stamping part into a plastic injection molding process, enabling efficient and low-cost manufacturing of complex, high-precision snap-fit ​​and mounting structures. Specifically, the first snap-fit ​​part 121 for pre-fixing the main control box 200 and the first mounting part 122 for final fastening can be integrally formed on the second chamber wall 120. This eliminates the need for additional welding or stamping, simplifying the manufacturing process and reducing production costs. In this way, the main control box 200 can quickly engage with the first engagement part 121 on the second bulkhead 120 made of plastic material through its corresponding second engagement part 210, thus completing the pre-fixation, thereby reducing the operational difficulty of workers during assembly and improving the assembly efficiency between the main control box 200 and the press chamber 100.

[0043] In one embodiment, both second bulkheads 120 are made of plastic.

[0044] Both second bulkheads 120 are made of plastic, meaning both side walls of the compressor compartment 100 are made of plastic, which significantly reduces the production cost of the compressor compartment 100. Furthermore, plastic is lightweight and requires less energy to process, which helps reduce the overall weight of the compressor compartment 100 and improves the refrigerator's energy efficiency. In addition, this symmetrical design with plastic on both sides also helps improve the overall stress balance of the refrigerator.

[0045] In one embodiment, the first bulkhead 110 is made of metal.

[0046] The first bulkhead 110 is made of metal, such as steel plate or aluminum alloy. As the main load-bearing structure of the compressor compartment 100, it, together with the refrigerator base plate, forms the basic frame of the mounting cavity 130, ensuring that the compressor compartment 100 has sufficient structural strength and rigidity to withstand the vibrations and mechanical loads generated by heavy components such as the compressor during operation. The metal material has excellent mechanical properties and durability, effectively resisting external impacts and preventing deformation, ensuring the long-term stability and safety of the compressor compartment 100. Simultaneously, the first bulkhead 110 serves as an intermediate support connecting the two plastic second bulkheads 120; its metal structure provides a reliable connection foundation, enhancing the structural integrity and torsional resistance of the entire compressor compartment 100.

[0047] In one embodiment, the first bulkhead 110 is made of metal, and both second bulkheads 120 are made of plastic. The two plastic second bulkheads 120 and the metal first bulkhead 110 can be assembled by separate splicing or partial connection, which takes into account both structural strength and manufacturing flexibility, avoids the problem of insufficient strength that may be caused by the overall plastic structure, and reduces mold complexity and production costs.

[0048] In one implementation, please refer to Figure 3 , Figure 4 ,and Figure 9 The first latching portion 121 is configured as a latching groove extending in a first direction. One end of the first latching portion 121 penetrates the end edge of the opening 131 and forms a latching inlet 123 communicating with the opening 131. The second latching portion 210 is configured as a latching protrusion and can be latched into the first latching portion 121 in the first direction through the latching inlet 123.

[0049] The first direction refers to the pushing direction of the main control box 200 during installation, and the slot extends along the first direction. One end of the slot passes through the end edge of the opening 131 of the compressor compartment 100, forming a slot inlet 123. The compressor compartment 100 has an opening 131 on one side to facilitate the assembly and maintenance of components such as the compressor and the main control box 200 within the compressor compartment 100. The edge of the opening 131 is the end edge of the opening 131. One end of the slot directly leads to the opening 131, forming an open slot inlet 123, allowing the locking protrusion of the main control box 200 to be aligned with the slot inlet 123 externally and pushed directly into the slot along the first direction until the locking protrusion slides into place along the slot, achieving a quick locking connection between the main control box 200 and the compressor compartment 100. The main control box 200 can be pre-fixed by pushing it directly in from the outside along the first direction during assembly, greatly simplifying the installation path and avoiding the problem of precise hovering and positioning required when screwing in the traditional vertical direction, significantly improving assembly efficiency and operational comfort. Secondly, the sliding fit between the protrusion and the slot provides stable positioning and support after insertion, ensuring that the main control box 200 remains in the same position during subsequent screw tightening, effectively preventing displacement and shaking, and improving installation accuracy and consistency.

[0050] In other implementation methods, the first snap-fit ​​portion 121 may not penetrate the end edge of the opening 131, the second snap-fit ​​portion 210 has a certain elasticity, the second snap-fit ​​portion 210 can be snapped into the slot along the second direction, and undergo elastic deformation during the snap-fit ​​process.

[0051] In one implementation, please refer to Figures 8 to 10 In the first direction, the two opposite groove sidewalls of the first snap-fit ​​portion 121 are arranged close to each other.

[0052] The two opposing slot sidewalls of the first locking part 121 refer to the two opposing sidewalls constituting the locking slot. They are not parallel but gradually narrow along the first direction. That is, the end of the locking slot where the locking entrance 123 is located is wider, gradually decreasing in width as it extends inward, forming a conical or wedge-shaped structure that is wider at the front and narrower at the back. The wide entrance end of the locking slot facilitates alignment, while the narrowing inward ensures a secure fit. When the locking protrusion slides into the locking slot along the first direction, the slot sidewalls can provide elastic or interference-force clamping action from both sides, enhancing the stability of the locking and effectively preventing the main control box 200 from shifting or accidentally dislodging due to external forces during vibration, handling, or subsequent assembly, thus improving the reliability of the pre-fixed state. When the initial alignment of the locking protrusion of the main control box 200 is slightly off, the wider part of the slot entrance can guide the locking protrusion smoothly into place, and during the sliding process, its position is gradually adjusted by the gradually narrowing sidewalls, ultimately achieving accurate positioning, improving assembly error tolerance and operational convenience. In addition, this clamping snap-fit ​​structure can improve connection rigidity without adding extra parts, share some of the load from the weight of the main control box 200 or external impacts, reduce reliance on subsequent screw fasteners, and extend the service life of the overall connection structure.

[0053] In other implementation methods, the two opposite groove sidewalls of the first snap-fit ​​portion 121 are arranged in parallel.

[0054] In one implementation, please refer to Figures 3 to 5 , Figure 9 and Figure 10 The first latching portion 121 extends limiting ribs 124 at the edges of the two slots in the second direction. The second latching portion 210 includes a first protrusion 211 and two second protrusions 212. The first protrusion 211 is disposed on the outer side of the main control box 200. The two second protrusions 212 are disposed on opposite sides of the first protrusion 211 along the second direction and are spaced apart from the outer side of the main control box 200. The second protrusion 212 has a limiting end face 2122 close to the outer surface of the main control box 200. The limiting end face 2122 abuts against the inner side of the limiting rib 124. The second direction intersects with the first direction.

[0055] Two limiting ribs 124 protrude towards each other, and their function is to provide a lateral stop surface to restrict the main control box 200 from disengaging from the slot in a third direction. The second latching part 210 includes a first protrusion 211 and two second protrusions 212. The first protrusion 211 is directly connected to the outer side of the main control box 200 and serves as the latching body for insertion into the slot. The two second protrusions 212 are located on both sides of the first protrusion 211 in a second direction and maintain a certain distance from the outer side of the main control box 200. Each second protrusion 212 has a limiting end face 2122 facing the inside of the main control box 200 (i.e., the end face near the center of the main control box 200). When the main control box 200 is pushed into the slot in the first direction, the limiting end face 2122 of the second protrusion 212 contacts the inner side of the limiting rib 124. At this time, the limiting rib 124 blocks the second protrusion 212 from the outside to prevent the main control box 200 from coming out of the slot.

[0056] In one implementation, please refer to Figure 4 and Figure 5 The first protrusion 211 is provided with two first guide surfaces 2111 opposite each other in the second direction, and the two first guide surfaces 2111 are arranged close to each other in the first direction.

[0057] The first protrusion 211 is provided with two opposing first guide surfaces 2111 in the second direction, and the two first guide surfaces 2111 are arranged close to each other in the first direction to form a wedge-shaped or conical guide structure that converges towards the snap-in direction. When the main control box 200 is pushed into the press chamber 100 in the first direction for snap-in, the front end of the first protrusion 211 on the main control box 200 enters the slot area first, and the first guide surfaces 2111 on both sides will first contact the edge of the slot of the first snap-in part 121 or the limiting protrusion 124. The first guide surfaces 2111 gradually narrow in the first direction, and this inclined structure can realize automatic correction and smooth introduction. Even if there is a slight positional deviation between the main control box 200 and the slot during the assembly process, the first guide surfaces 2111 can push the main control box 200 to the correct position through the inclined squeezing action, ensuring that the snap-in protrusion slides smoothly into the slot, avoiding jamming, scratching or assembly failure caused by misalignment, and significantly improving the fault tolerance rate and smoothness of operation of the assembly. Secondly, this structure reduces the precision requirements of manual operation. Workers or automated equipment do not need to align the main control box 200 with excessive precision when pushing it, thus achieving quick and reliable pre-fixation and further improving assembly efficiency. In addition, the inclined arrangement of the two first guide surfaces 2111 facilitates the demolding of the main control box 200 body during the production process to form the first protrusion 211.

[0058] In one implementation, please refer to Figure 4 and Figure 5The first protrusion 211 is provided with two first guide surfaces 2111 opposite each other in the second direction. The first guide surfaces 2111 have an angle α with the first direction, and the angle α satisfies: 2°≤α≤5°.

[0059] The included angle α between the first guide surface 2111 and the first direction satisfies the condition: 2° ≤ α ≤ 5°. When the included angle α is too small (less than 2°), the first guide surface 2111 is too straight, its guiding effect is not obvious, and it is difficult to effectively correct assembly deviations, especially when there are manufacturing tolerances or deformation during handling, which can easily cause jamming; it is also not conducive to the demolding of the main control box 200 to form the first protrusion 211. When the included angle α is too large (more than 5°), the slope is too steep, which will lead to excessive lateral force during the introduction process, which will not only increase the pushing resistance, but may also cause scratches, deformation or even structural damage to plastic parts (such as the second bulkhead 120 or the main control box 200 body). Therefore, controlling the included angle α between 2° and 5° is the optimal balance range between ensuring good guiding performance, easy demolding of the first protrusion 211 and low insertion force. Within this range, the first guide surface 2111 can effectively guide the main control box 200 to automatically correct position deviations and ensure that the card protrusion accurately enters the card slot. It can also facilitate the demolding of the main control box 200 to form the second carding part 210, and maintain a low assembly force, improving the ease of operation. It is suitable for both manual and automated assembly scenarios.

[0060] In one implementation, please refer to Figure 5 and Figure 6 The second protrusion 212 has a second guide surface 2121 on the side away from the first protrusion 211, and the two second guide surfaces 2121 are arranged close to each other in the first direction.

[0061] The second protrusion 212 has a second guide surface 2121 on the side away from the first protrusion 211, and the two second guide surfaces 2121 are arranged close to each other in the first direction to form an inclined structure that converges towards the front end in the insertion direction (first direction). The second guide surface 2121 is located at the outer end of the second protrusion 212 and serves as one of the guiding parts that first contact the press chamber 100 during the assembly process of the main control box 200. When the main control box 200 is pushed in along the first direction, it can first contact the groove sidewall of the first locking part 121, and achieve preliminary guidance and position correction through its inclined surface. The guiding structure of the second guide surface 2121 can correct the misalignment in the second direction through the inclined action when the main control box 200 is not yet fully aligned, guiding the second protrusion 212 to slide smoothly into the slot, avoiding scratches, jamming, or assembly obstruction caused by initial offset. Furthermore, the second guide surface 2121 and the first guide surface 2111 on the first protrusion 211 form a multi-level collaborative guiding system, which improves the overall assembly smoothness and success rate. In addition, the inclined setting of the two second guide surfaces 2121 also facilitates the demolding of the main control box 200 body during the production process to form the second protrusion 212.

[0062] In one implementation, please refer to Figure 5 and Figure 6 The second protrusion 212 has a second guide surface 2121 on the side away from the first protrusion 211. The second guide surface 2121 has an angle β with the first direction, and the angle β satisfies: 2°≤β≤5°.

[0063] The included angle β between the second guide surface 2121 and the first direction satisfies the condition: 2° ≤ β ≤ 5°. When the included angle β is less than 2°, the second guide surface 2121 is too straight, resulting in weak guiding effect and difficulty in effectively correcting initial misalignment during assembly. This is especially problematic when there are component tolerances or installation posture deviations, which can easily lead to jamming difficulties or scratches; furthermore, it makes demolding and forming the second protrusion 212 difficult. When the included angle β exceeds 5°, the slope is too steep, leading to excessive lateral force during assembly. This not only significantly increases the pushing resistance but may also cause deformation, cracking, or other damage to the plastic second protrusion 212 or the press chamber 100 limiting rib 124 due to stress concentration, affecting structural durability and assembly reliability. Therefore, the included angle β is controlled between 2° and 5° to ensure that the second protrusion 212 is easy to demold, has good guiding performance, and low assembly force.

[0064] In one implementation, please refer to Figure 9 and Figure 10 The spacing between the two limiting ribs 124 is set to gradually decrease in the first direction.

[0065] The distance between the two limiting ribs 124 gradually decreases in the first direction. That is, in the direction extending from the card inlet 123 into the card slot, the distance between the two limiting ribs 124 gradually narrows, forming an inwardly converging wedge-shaped space. This structure allows the first protrusion 211 of the main control box 200 to pass through a guide channel with a wider inlet and a gradually narrowing interior (formed by the gap between the two limiting ribs 124) during the pushing process in the first direction. Thus, after assembly, the limiting ribs 124 can apply a moderate elastic or interference fit force to the first protrusion 211 from both sides, achieving a tighter limiting. At this time, the end face of at least one limiting rib 124 in the second direction abuts against the first guide surface 2111 of the first protrusion 211.

[0066] The gradually narrowing spacing of the limiting ribs 124 matches the shape of the first protrusion 211 and the second protrusion 212 of the main control box 200. In the initial insertion stage, the wider entrance facilitates the first protrusion 211's smooth passage between the two limiting ribs 124, reducing alignment difficulty. As insertion progresses, the narrowing spacing forces the first protrusion 211 to gradually center, automatically correcting assembly deviations and achieving a smooth transition from easy entry to precise positioning, significantly improving assembly tolerance and operational fluency. Secondly, once the main control box 200 is fully in place, the shape changes of the limiting ribs 124 and the second protrusion 212 are almost identical, allowing for effective contact. This effectively prevents the second protrusion 212 from detaching, thus suppressing wobbling or loosening of the main control box 200 in the second direction, enhancing the rigidity and stability of the pre-fixed structure. Especially during transportation, handling, or refrigerator operation vibrations, this prevents the main control box 200 from detaching or wearing due to repeated impacts.

[0067] In one implementation, please refer to Figure 5 and Figure 7 The limiting end face 2122 has an angle θ with the first direction, and the angle θ satisfies: 1°≤θ≤3°.

[0068] The included angle θ between the limiting end face 2122 and the first direction satisfies: 1°≤θ≤3°. The setting of the included angle θ fully considers the demolding feasibility and manufacturing economy of the plastic part. The limiting end face 2122 is located on the second protrusion 212, which is usually integrated into the second bulkhead 120 or the outer shell of the main control box 200 made of plastic material and manufactured by injection molding. When the limiting end face 2122 is completely parallel to the first direction (θ=0°), significant demolding resistance will be generated during the demolding process, and even an undercut structure may be formed, making it difficult for the plastic part to be ejected smoothly, and easily causing defects such as scratches, deformation or puncture, which seriously affects the product yield and mold life.

[0069] By setting the limiting end face 2122 at an angle θ of 1° to 3° with the first direction, forming a slightly inclined surface, the problem of undercut can be effectively avoided. During mold opening, this inclined surface has a certain guiding angle with the movement direction of the mold core, allowing the plastic part to smoothly detach from the mold core surface along the inclined surface during ejection, significantly reducing demolding resistance, minimizing frictional damage, and improving the smoothness and stability of demolding. Simultaneously, this angle design helps to evenly distribute the ejection force, preventing cracking or warping of the plastic part due to localized stress concentration, thus improving molding quality.

[0070] In one implementation, please refer to Figures 3 to 5 , Figure 9 The first mounting part 122 is configured as a mounting hole located at the end edge of the opening 131, and the second mounting part 220 is configured as a mounting through hole, which is fastened to the mounting hole by screws.

[0071] The first mounting part 122 is configured as a mounting hole located at the edge of the opening 131, and the second mounting part 220 is correspondingly configured as a mounting through hole. During assembly, screws pass through the mounting through hole on the main control box 200 and are locked into the first mounting hole at the edge of the opening 131 of the press chamber 100, thereby achieving a rigid connection between the main control box 200 and the press chamber 100. This mounting hole is located on the edge area of ​​the second chamber wall 120 facing the opening 131 of the mounting cavity 130. Its open and easily accessible location avoids the problem of tools being unable to enter or operations being restricted due to structural obstruction, facilitating operation with manual or automatic tools (such as electric screwdrivers or automatic screw-driving machines), greatly improving the convenience and efficiency of screw fastening operations. After the main control box 200 is pre-fixed by snap-fit, workers or automated equipment can directly align and tighten the screws from one side of the opening 131, which is convenient and quick. The snap-fit ​​structure provides initial positioning and support, ensuring the main control box 200 is stably positioned; the screw connection reinforces the connection strength, ensuring long-term reliability. The two have a clear division of labor, which ensures both assembly speed and structural strength requirements.

[0072] In one implementation, please refer to Figure 9 The number of first mounting parts 122 is configured to be one.

[0073] The number of first mounting parts 122 is configured as one. Specifically, the first mounting part 122 is a mounting hole set at the end edge of the opening 131. Correspondingly, the second mounting part 220 on the main control box 200 is also configured as a mounting through hole. A single screw passes through the mounting through hole and is locked into the mounting hole to achieve the final fastening connection between the main control box 200 and the compressor chamber 100.

[0074] By using only a single first mounting part 122, the fastening structure is significantly simplified, the number of screws is reduced, and the locking operation becomes more efficient and cost-effective. After the main control box 200 is pre-fixed via the snap-fit ​​structure, workers or automated equipment only need to complete one alignment and locking action to finish all fastening operations, significantly shortening assembly time and increasing production cycle time. The single-screw structure helps reduce weight, save materials, and reduce drilling processes, further reducing manufacturing costs. It is worth mentioning that the first snap-fit ​​part 121 and the second snap-fit ​​part 210 already undertake the main positioning, support, and most load transfer functions, while the single screw acts as an "anti-loosening safety" and provides local reinforcement. The two work together, so even with only a single screw, the stability of the connection between the main control box 200 and the press chamber 100 can be guaranteed; at the same time, it avoids the excessive constraints, inefficiency, and high costs associated with multiple screws.

[0075] In one implementation, please refer to Figures 3 to 5 The second latching part 210 is configured as a latching protrusion, and the main control box 200 is also provided with a mounting lug 230. The second mounting part 220 is provided on the mounting lug 230, and the mounting lug 230 and the second latching part 210 protrude and are provided on the same outer side surface of the main control box 200.

[0076] By having both the mounting lug 230 and the second snap-fit ​​portion 210 protrude from the same outer side surface of the main control box 200, the connection functions of the main control box 200 are concentrated and integrated in the same side wall area, forming a highly integrated assembly interface. During assembly, the main control box 200 achieves quick snap-fit ​​pre-fixation with the first snap-fit ​​portion 121 on the press chamber 100 through the snap-fit ​​protrusion on this side. Simultaneously, the mounting through-hole on the mounting lug 230 aligns with the mounting hole on the press chamber 100 to complete screw fastening, achieving final tightening. Workers or automated equipment only need to push the main control box 200 from the open side 131 of the press chamber 100 along the first direction to complete the snap-fit, and then perform screw fastening in the same position. There is no need to go around to other sides or repeatedly adjust the working angle, which greatly improves the concentration and convenience of operation, shortens the work path, and improves assembly efficiency. In addition, the mounting lug is located near or adjacent to the mounting lug 230, which makes the pre-fixing point and the final fastening point close in space, forming a stable local connection area, which is beneficial to improving the rigidity and stability of the main control box 200 installation.

[0077] In one implementation, please refer to Figure 2 The first bulkhead 110 and the second bulkhead 120 are separately formed and assembled into one unit by fasteners.

[0078] The first bulkhead 110 is typically made of metal and formed through stamping or bending processes to ensure sufficient structural strength and rigidity to support heavy-duty components such as the compressor. The two second bulkheads 120, on the other hand, are made of plastic and integrally molded using injection molding, facilitating the integration of complex snap-fit ​​and mounting structures. After each bulkhead is formed, the first bulkhead 110 is securely connected to the second bulkheads 120 on both sides using screws, rivets, or other fasteners to form the complete compressor compartment 100 structure.

[0079] Split molding breaks through the limitations of traditional one-piece stamping structures in forming complex geometries, allowing the plastic second bulkhead 120 to be freely designed with intricate structures that meet the rapid snap-fit ​​pre-fixing requirements of the main control box 200, such as tapered grooves, guide bevels, and limiting ribs 124, significantly improving assembly functionality and process freedom. Meanwhile, the metal first bulkhead 110 can focus on optimizing load-bearing performance, balancing strength, durability, and electromagnetic shielding effectiveness.

[0080] The metal first bulkhead 110 and the plastic second bulkhead 120 are manufactured using their respective mature process systems, avoiding the high costs associated with composite material molding or large, complex metal stamping dies. In particular, the plastic parts can achieve integrated manufacturing of complex features through high-precision injection molding, reducing subsequent processing and assembly steps and improving production efficiency. Furthermore, the split design enhances production and maintenance flexibility; if either the first bulkhead 110 or the second bulkhead 120 is damaged, it can be replaced individually without requiring complete scrapping, thus reducing maintenance costs.

[0081] In one implementation, please refer to Figure 2 One of the second bulkheads 120 is provided with a first snap-fit ​​part 121 and a first mounting part 122, and the other second bulkhead 120 is provided with a heat dissipation channel 140, which connects the mounting cavity 130 and the outside of the compressor chamber 100.

[0082] One of the second bulkheads 120 is provided with a first snap-fit ​​part 121 and a first mounting part 122 for snap-fit ​​pre-fixation and screw locking of the main control box 200, while the other opposite second bulkhead 120 is provided with a heat dissipation channel 140. The heat dissipation channel 140 passes through and connects the mounting cavity 130 and the outside of the compressor chamber 100 to form an effective ventilation path, so that the heat generated by the main control box 200 and the compressor during operation can be discharged in time, avoiding heat accumulation that could cause overheating of electronic components, performance degradation or shortened life.

[0083] By concentrating the installation functions of the main control box 200 on one side of the second bulkhead 120, complex structures such as slots, limiting ribs 124, guide surfaces, and mounting holes can be fully integrated on this side, ensuring efficient and reliable assembly. Meanwhile, by independently setting the heat dissipation function on the other side of the second bulkhead 120, interference between the installation and ventilation structures is avoided. This allows for independent design of airflow paths, opening areas, and dustproof structures based on heat dissipation requirements, improving heat dissipation efficiency and the rationality of airflow. Furthermore, the two bulkheads each fulfill different functions, facilitating modular design and standardized production, and enhancing the flexibility of product development.

[0084] In addition, the main control box 200 is usually an electronic control component, which is relatively sensitive to temperature. By avoiding direct ventilation areas, the risk of condensation caused by intense convection of hot and cold air can be prevented. Heat is mainly discharged through natural convection on the opposite heat dissipation channel 140 or by the airflow driven by the compressor during operation, achieving a good thermal management effect of "functional isolation and directional heat dissipation".

The specific structure of the compressor compartment is as described in the above embodiments. Since this refrigerator adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
