[0038] BRIEF DESCRIPTION OF THE DRAWINGS

[0039]

[0040]

[0041] The implementation, functional features and advantages of the present application will be further described with reference to the embodiments and the accompanying drawings. DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0043] In the related art, the cover plate of the refrigeration device is installed in the following manner: a clamping groove with the opening upward is arranged on the bottom shell, a clamping buckle is arranged at the lower end of the cover plate, during installation, the clamping buckle is inserted into the clamping groove, and then the upper end and the two sides of the cover plate are fixedly connected with the bottom shell by using bolts. In this installation manner, a large number of (at least five, specifically, three at the upper end and two at the two sides) bolts need to be installed, the installation efficiency is low, a large number of parts are consumed, and due to the large number of bolts, a plurality of screw holes need to be aligned, which invisibly increases the requirement for the dimensional accuracy of the bottom shell and the cover plate; and during installation, since the clamping buckle at the lower end of the cover plate needs to be inserted into the clamping groove first, the cooperation between the clamping groove and the clamping buckle also needs high accuracy, so as to avoid that the clamping buckle cannot be inserted, or that due to the large reserved space of the clamping groove, the cover plate is inclined backward due to gravity, thereby affecting the accuracy of the alignment of the screw holes or causing the joint to be too large.

[0044] The present application provides a refrigeration device 100, such as a refrigerator, a freezer, etc., to solve the technical problems of complex installation and low efficiency of the existing refrigerator cover plate 3. The following will be described in conjunction with the accompanying drawings.

[0045] Please refer to Figure 1 andFigure 2 The refrigeration device 100 includes a housing and a cover plate 3. The housing includes a back plate 2 and a bottom shell 1 connected to each other. The bottom shell 1 defines an installation cavity 11 with an opening. The back plate 2 is located above the opening, and a hanging hole 21 is provided at the lower end of the back plate 2. The upper end of the cover plate 3 is provided with a hook 32. The hook 32 is inserted into the hanging hole 21 so that the cover plate 3 is suspended from the back plate 2 and covers the opening. The side of the cover plate 3 is engaged with the bottom shell 1.

[0046] In the refrigeration device 100 provided in this application, a hanging hole 21 is provided at the lower end of the back plate 2, and a hook 32 is provided at the upper end of the cover plate 3. At the same time, a snap-fit ​​structure is provided on the side of the cover plate 3 and the bottom shell 1. When installing the cover plate 3, the cover plate 3 can be suspended on the back plate 2 by the cooperation of the hook 32 and the hanging hole 21. Then, the cover plate 3 is rotated to snap its side with the bottom shell 1, thus realizing the installation of the cover plate 3. The installation is convenient and efficient. At the same time, since most of the refrigeration pipes and wiring harnesses in the installation cavity 11 are located in the upper part of the installation cavity 11 or exit from the upper part of the bottom shell 1, this installation method avoids the need to drive bolts 6 into the upper end of the cover plate 3. This can avoid the pipes in the installation cavity 11 being accidentally touched by the bolts 6, which could cause damage to the pipes and affect the operation of the refrigeration device 100.

[0047] Furthermore, during installation, due to the weight of the cover plate 3 itself, when the hook 32 is inserted into the hanging hole 21, the cover plate 3 naturally hangs down, allowing it to accurately cover the opening. This ensures that the side of the cover plate 3 aligns precisely with the bottom shell 1, facilitating subsequent snap-fitting and serving a pre-positioning function. Additionally, the snap-fitting of the side of the cover plate 3 with the bottom shell 1 also ensures a good fit between the cover plate 3 and the bottom shell 1.

[0048] The shell can be the external structure of the refrigeration device 100, or it can be a partial shell structure component existing within the box that constitutes the external structure. For example... Figure 1 and Figure 3 As shown, the housing may include a bottom shell 1 and a back plate 2. The bottom shell 1 has a back side, and an installation cavity 11 is formed inside the bottom shell 1, which can be used to house the compressor. The installation cavity 11 extends through the back side of the bottom shell 1 and forms an opening on the back side. The back plate 2 is connected to the back side of the bottom shell 1 and is located above the opening.

[0049] For ease of description, this article uses Figure 1 The installation orientation of the refrigeration device 100 embodiment shown is used as an example for explanation. As shown in the figure, in this embodiment, the refrigeration device 100 has a front side facing the user and a rear side facing away from the user. The back plate 2 is located on the rear side of the refrigeration device 100, and the mounting cavity 11 is located at the bottom of the refrigeration device 100 with its opening facing the rear.

[0050] The bottom shell 1 can be of an integral structure or can be combined by multiple plate members. In some embodiments, the bottom shell 1 comprises a first bottom plate 12 and a second bottom plate 13 oppositely arranged in the up-down direction, and two side supports arranged between the first bottom plate 12 and the second bottom plate 13, the side supports comprising a main plate and a mounting plate 15 arranged at the rear end of the main plate. Among them, the first bottom plate 12 is located above the second bottom plate 13, the two main plates are oppositely arranged in the left-right direction, and the two main plates, the first bottom plate 12 and the second bottom plate 13 are connected to each other to jointly enclose the mounting cavity 11, and the rear ends of the two main plates, the rear end of the first bottom plate 12 and the rear end of the second bottom plate 13 constitute the opening rim; the mounting plate 15 extends in the up-down direction and faces the rear side, and the two mounting plates 15 are respectively located on the left side and the right side of the opening.

[0051] Please refer to Figure 9 The back plate 2 as a whole can be in the shape of a plate or a cover body and is arranged above the opening. In some embodiments, the shell can further comprise two wall plates 7 oppositely arranged in the left-right direction, and the bottom shell 1 and the back plate 2 are located between the two wall plates 7. In order to fix the back plate 2, the rear side of the wall plate 7 can be formed with a U-shaped groove extending in the up-down direction, and the two sides of the back plate 2 correspond to the U-shaped groove and are formed with a first folded edge folded forward, and the first folded edge is inserted into the U-shaped groove. Further, the back plate 2 can also be connected with the first bottom plate 12.

[0052] In some embodiments, the side edge of the mounting plate 15 away from the main plate can also be folded to form a second folded edge, and the second folded edge is inserted into the U-shaped groove.

[0053] The lower end of the back plate 2 is provided with a hanging hole 21 for cooperating with a hook 32. The hanging hole 21 can be arranged as a strip-shaped hole extending in the width direction of the back plate 2 (i.e. the left-right direction). The hanging hole 21 penetrates through the back plate 2.

[0054] The hanging hole 21 can be arranged as one or multiple, when arranged as multiple, the multiple hanging holes 21 can be arranged in the left-right direction at intervals, and meanwhile, the hook 32 is also arranged as multiple to correspond to the multiple hanging holes 21, so that the multiple hooks 32 and the multiple hanging holes 21 can correspond one by one. In some embodiments, the hanging hole 21 is arranged as one, and the hanging hole 21 is a relatively long hole, and correspondingly, the hook 32 is arranged as a relatively long hook 32 corresponding to the length of the hanging hole 21. In this way, the hook 32 and the hanging hole 21 are relatively simple to manufacture, and the requirement for manufacturing precision is relatively low, and in the process of installation, it is easy to align and has relatively high efficiency.

[0055] Please refer to Figure 10 and Figure 11The cover plate 3 can be in the shape of a plate or a cover, and is arranged at the opening to cover the opening and protect the compressor in the mounting cavity 11. The cover plate 3 can be made of metal, for example, a sheet metal part, which is simple to manufacture and has the advantages of light weight, firmness, corrosion resistance, etc. In some embodiments, the cover plate 3 can be provided with heat dissipation holes for facilitating heat dissipation. In other embodiments, the cover plate 3 can be provided with wiring holes for facilitating wiring, through which refrigeration pipelines or wiring harnesses, etc. can pass.

[0056] Please refer to Figure 6 and Figure 8 The mounting plate 15 extends in the up-down direction and has opposite inner and outer sides, wherein the outer side refers to the side of the mounting plate 15 facing the cover plate 3, i.e. the rear side of the mounting plate 15 in the illustrated embodiment. The outer side of the mounting plate 15 is formed with a clamping groove 16 extending in the up-down direction. The cover plate 3 includes a cover body 31 and two side wings 33 arranged on opposite sides of the cover body 31. The side wings 33 extend from the side of the cover body 31 facing the mounting plate 15; specifically, the side wings 33 extend forward from the side edges of the cover body 31 and correspond to the clamping grooves 16, so as to be inserted into the clamping grooves 16. One of the side wings 33 is inserted into one of the clamping grooves 16 for clamping cooperation, so as to achieve clamping of the cover plate 3 with the bottom shell 1, and the two sides of the cover plate 3 are clamped with the bottom shell 1, which helps to improve the fitting effect of the cover plate 3.

[0057] The clamping groove 16 has opposite first and second groove walls 161 and 162, and the first and second groove walls 161 and 162 are opposite in the width direction of the opening (i.e. the left-right direction). The distance between the first and second groove walls 161 and 162 is the width of the clamping groove 16. In some embodiments, the first groove wall 161 is recessed in the direction away from the second groove wall 162 at the portion close to the groove bottom, so that the width of the clamping groove 16 at the groove bottom is greater than the width at the groove opening; for example, Figure 6As shown, the front end of the first slot wall 161 is recessed to the right, thereby forming a step with the rear end of the first slot wall 161, so that the spacing between the front end of the first slot wall 161 and the second slot wall 162 is greater than the spacing between the rear end of the first slot wall 161 and the second slot wall 162, so that the slot width of the card slot 16 presents a contraction effect at the position close to the slot opening. The side wing 33 has a first side and a second side oppositely arranged in the left-right direction, the side wing 33 is bent and protrudes from the first side to the second side, and a bending portion is formed to divide the side wing 33 into a first extension segment 331 and a second extension segment 332, wherein the first extension segment 331 is connected to the cover body 31, and the second extension segment 332 is connected to one end of the first extension segment 331 away from the cover body 31. In this way, when the side wing 33 is inserted into the card slot 16, the first extension segment 331 can abut against the second slot wall 162, and the bending portion can abut against the recessed portion of the first slot wall 161, so that the side wing 33 can abut against both slot walls of the card slot 16. At the same time, the bending portion abuts against the recessed portion, and the design of the slot opening contraction can limit the backward withdrawal of the bending portion from the card slot 16, which helps to improve the clamping firmness between the side wing 33 and the card slot 16. Since both side wings 33 of the cover plate 3 are provided with such a bent and protruding structure, they can well cooperate with the two card slots 16, so that the cover plate 3 can be tightly attached to the two mounting plates 15 without any gap, thereby ensuring the installation reliability of the cover plate 3.

[0058] To improve the installation efficiency of the cover plate 3, in some embodiments, the cover plate 3 further comprises a lead-in portion 333. The lead-in portion 333 is connected between the upper end of the first extension segment 331 and the upper end of the second extension segment 332, so that the peripheral side surface of the second extension segment 332 and the peripheral side surface of the first extension segment 331 are smoothly transitioned through the peripheral side surface of the lead-in portion 333. Please refer to Figure 11 and Figure 12 , the upper end of the first extension segment 331 is slightly higher than the upper end of the second extension segment 332, and a triangular area is defined between the upper end of the first extension segment 331 and the upper end of the second extension segment 332, and the lead-in portion 333 is formed in the triangular area and connects the upper ends of the first extension segment 331 and the second extension segment 332. In this way, as Figure 12The middle dotted line shows that the circumferential surface of the second extending section 332 and the circumferential surface of the first extending section 331 are connected through the circumferential surface of the lead-in section 333, and the transition is approximately a straight line. When installing the cover plate 3, the cover plate 3 is first hung on the back plate 2, and then the cover plate 3 is rotated forward to make the side wing 33 contact the clamping groove 16. At this time, the upper end of the side wing 33 first contacts the upper end of the clamping groove 16. The design of the first extending section 331 and the second extending section 332 makes the upper end of the side wing 33 a bent line type. This type is not easy to insert into the clamping groove 16. The setting of the lead-in section 333 makes the upper end of the side wing 33 change from a bent line type to a straight line, so that the side wing 33 can be easily inserted into the clamping groove 16, which helps to reduce the clamping difficulty and improve the installation efficiency.

[0059] Further, referring to Figure 13 , the lead-in section 333 has a back surface 3331 facing the opening; specifically, taking the left side wing 33 on the cover plate 3 as an example, the back surface 3331 of the lead-in section 333 on the side wing 33 faces the rear side. In some embodiments, the back surface 3331 is set as a flat surface that gradually inclines in the direction of approaching the bending part from top to bottom. The setting of the flat surface makes the lead-in section 333 more easily inserted into the clamping groove 16. At the same time, the design of the inclined surface that gradually inclines in the direction of approaching the bending part from top to bottom makes the side wing 33 transition from a straight line, a thin part to a bent part, a thick part, which helps the other parts of the side wing 33 to be smoothly inserted into the clamping groove 16.

[0060] Numerous electronic components are distributed in the installation cavity 11, and when the transport refrigeration device 100 is in transport, it is easy to be jolted. In order to avoid these components from being damaged due to jolting, in some embodiments, the inner side of the installation plate 15 is further provided with a reinforcing piece 4 extending in the up-down direction. The reinforcing piece 4 can be welded on the inner side of the installation plate 15 to support in the up-down direction. The reinforcing piece 4 can be reinforcing iron.

[0061] Further, as Figure 6As shown, the mounting plate 15 arches from the outside to the inside opposite to the outside, so as to form the clamping groove 16 by recessing on the outside and form an arch bulge on the inside. The reinforcing member 4 includes a main body section 41, a connecting section 42 and a flanging section 43. Among them, the main body section 41 is bent to form a support groove adapted to the arch bulge, so as to cover the arch bulge; the connecting section 42 extends from the side of the main body section 41 in a direction away from the main body section 41 for connecting the flanging section 43 and the main body section 41; the flanging section 43 is bent from the side of the connecting section 42 away from the main body section 41 towards the inside. In this embodiment, the reinforcing member 4 is bent multiple times and is generally in a "U" shape. Since the reinforcing member 4 has multiple bending sections, compared with the setting of a flat plate member, it has stronger supporting strength in the up and down directions.

[0062] To prevent water from entering the installation cavity 11 and damaging the electronic components, causing safety accidents, in one embodiment, the refrigeration device 100 further includes a water blocking part 51, as Figure 4 and Figure 7 shown, the water blocking part 51 is arranged above the hanging hole 21 and protrudes from the back plate 2. When water flows down along the back plate 2, the water blocking part 51 can block the water flow from flowing into the installation cavity 11 through the hanging hole 21.

[0063] Specifically, as Figure 5 shown, in a specific embodiment, the refrigeration device 100 further includes a water blocking member 5. The water blocking member 5 is arranged on the side of the back plate 2背离 the cover plate 3 and corresponds to the hanging hole 21. The side of the water blocking member 5 facing the cover plate 3 is recessed to form a让位 space 52 communicating with the hanging hole 21 between the water blocking member 5 and the back plate 2. When the hook 32 is inserted into the hanging hole 21, the hook 32 can be accommodated in the让位 space 52. The formation of the让位 space 52 can, on the one hand, prevent the hook 32 from interfering with other components in the housing, and on the other hand, make the cover plate 3 fit more closely to the back plate 2, reducing the gap between the cover plate 3 and the back plate 2. The upper end of the water blocking member 5 passes through the hanging hole 21 and extends in a direction away from the back plate 2 to form the water blocking part 51.

[0064] Furthermore, in some embodiments, the water blocking part 51 can be set such that the top of the water blocking part 51 abuts against the top of the hanging hole 21 (i.e., the upper hole wall located above) and gradually slopes downward in a direction away from the back plate 2. In this way, the water blocking part 51 is in an inclined plane, which helps the water flow away along its surface, avoiding too much water remaining on the water blocking part 51 and further causing water to seep into the installation cavity 11 from the contact place between the top of the water blocking part 51 and the top of the hanging hole 21.

[0065] It should be noted that there is an unclear expression "所述背板2背离所述盖板3的一侧" in the original text, which may need to be further clarified in the actual context. Also, "让位空间52" is a self-created term here, and it might be better to use a more standard or commonly understood name if possible.In addition, in an embodiment, the lower end of the cover plate 3 is fixedly connected with the bottom shell 1 by means of the bolts 6. Not only the lower end of the cover plate 3 can be well fixed on the bottom shell 1, but also the bolt 6 connection mode has better firmness, which can avoid the user from mistakenly disassembling the cover plate 3.

[0066] Further, in some embodiments, as shown in Figure 1 The bolts 6 are provided in two, and the two bolts 6 are arranged at the left side and the right side of the cover plate 3, so that in the case of using fewer bolts 6, the lower end of the cover plate 3 can be tightly attached to the bottom shell 1, the installation firmness is better, the parts are less consumed, and the installation steps are simple.
