Description

Technical Field

[0001] This application relates to a refrigerator. More particularly, it relates to the mounting and securing of the refrigerator's rear cover. Background Technology

[0002] Refrigerators have compressors to compress the refrigerant. The compressor is typically housed in a compressor compartment. To seal the compressor compartment from the back of the refrigerator, a rear cover is provided. Currently, the rear cover is usually secured to the refrigerator's base plate with multiple screws. Because the base plate is thin, screw fasteners, especially along the upper edge of the rear cover, need to be attached to the base plate to secure the rear cover to the foam-coated casing. This process involves numerous steps, resulting in high material and labor costs. Utility Model Content

[0003] The purpose of embodiments of this application is to provide an improved refrigerator that simplifies the installation structure of the rear cover.

[0004] According to a first aspect of this application, an embodiment of this application provides a refrigerator, characterized in that the refrigerator comprises:

[0005] A compressor housing suitable for accommodating a compressor;

[0006] Rear cover plate, the rear cover plate being adapted to cover the compressor housing;

[0007] The socket structure is such that the upper edge of the cover plate of the rear cover is adapted to be inserted into the socket structure from bottom to top;

[0008] The socket structure includes a retaining edge adapted to block the upper edge of the cover plate from behind.

[0009] The upper part of the cover plate is limited by the interlocking structure and the fit between the interlocking structure and the upper edge of the cover plate, which makes the installation of the rear cover plate of the compressor compartment easier and thus improves production efficiency. Furthermore, this method makes it possible to reduce the use of other fixing devices. For example, fixing devices such as screws used to fix the upper edge of the cover plate can be eliminated, and corresponding fixing auxiliary mechanisms such as screw fixing blocks located in the foam layer of the housing can be eliminated accordingly.

[0010] It should be understood that the insertion of the socket structure from bottom to top along the upper edge of the rear cover can include an implementation in which the socket structure is inserted from bottom to top along the vertical direction along the upper edge of the rear cover, and an implementation in which the socket structure is inserted from bottom to top along a direction forming an angle with the relative vertical direction.

[0011] According to an alternative embodiment of this application, the retaining edge extends obliquely forward toward the inner side of the upper edge of the cover plate in an upward direction. The oblique forward direction of the retaining edge in the upward direction makes the inlet size of the socket structure larger than its bottom size, which facilitates the installation of the rear cover plate, for example, the rear cover plate can be inserted into the socket structure from bottom to top in an inclined position.

[0012] According to an optional embodiment of this application, the socket structure includes a support portion that, in the assembled state, supports the rear cover plate from the front. Support on the other side is achieved through the support portion.

[0013] According to an optional embodiment of this application, the socket structure includes an upper stop adapted to block the upper edge of the rear cover plate from above. The upper stop allows the rear cover plate to be blocked from above.

[0014] According to an optional embodiment of this application, the refrigerator includes a lower fixing structure for fixing the lower part of the rear cover. The lower fixing structure allows the rear cover to be fixed from below, thereby achieving a stable fixation.

[0015] According to an optional embodiment of this application, the refrigerator includes an outer shell covered with heat insulation material, the outer shell including a back panel, a bottom panel and a side panel in contact with the heat insulation material, the back panel being located above the rear cover, the bottom panel retracting upward at the rear to form the compressor housing, and the side panels laterally covering the compressor housing.

[0016] According to an optional embodiment of this application, the socket structure is located between the back plate and the bottom plate.

[0017] According to an optional embodiment of this application, the back plate includes a back plate body and a bent portion at the lower end of the back plate body, the bent portion forming the retaining edge.

[0018] This allows for the easy implementation of a socket structure.

[0019] According to an optional embodiment of this application, the bending portion includes a first section bent rearward relative to the backplate body and a second section bent downward relative to the first section, the second section forming the retaining edge. This facilitates control of the size of the socket end of the socket structure using the first section and allows for convenient formation of the retaining edge using the second section.

[0020] According to an alternative embodiment of this application, the base plate extends in front of the back panel body and overlaps with the back panel body along the front-rear direction of the refrigerator.

[0021] According to an alternative embodiment of this application, the first section forms the upper stop.

[0022] According to an alternative embodiment of this application, the second segment is bent obliquely downward relative to the first segment.

[0023] According to an optional embodiment of this application, the base plate includes a base plate body and a bent portion at the upper end of the base plate body, the bent portion forming the retaining edge. Thus, a socket structure can be achieved through the base plate.

[0024] According to an optional embodiment of this application, the bending portion includes a first section bent backward relative to the base plate body and a second section bent downward relative to the first section, the second section forming the retaining edge.

[0025] According to an alternative embodiment of this application, the first section forms the upper stop.

[0026] According to an alternative embodiment of this application, the second segment is bent obliquely downward relative to the first segment.

[0027] According to an optional embodiment of this application, the lower fixing structure includes a cover plate through hole located at the lower part of the rear cover plate.

[0028] According to an optional embodiment of this application, the lower fixing structure includes a flanged through hole provided on the flange of the side plate, a plastic reinforcing member accommodated by the side plate, and a screw, wherein the screw passes through the cover plate through hole and the flanged through hole and is screwed into the plastic reinforcing member to fix the rear cover plate.

[0029] According to an alternative embodiment of this application, the support portion includes a first support portion formed by the base plate, the first support portion being adapted to support the upper edge of the cover plate of the rear cover plate.

[0030] According to an optional embodiment of this application, the first support portion has a vertical first support surface for supporting the upper edge of the cover plate.

[0031] According to an optional embodiment of this application, the support portion includes a second support portion formed by the flange of the side plate.

[0032] This provides stable support for the rear cover.

[0033] According to an optional embodiment of this application, the free end of the retaining edge facing away from the rear cover plate is provided with a stacked edge structure. This increases strength and avoids sharp edges.

[0034] According to an optional embodiment of this application, the overlapping edge structure is an overlapping edge structure with inner edges.

[0035] According to an optional embodiment of this application, the socket structure has a socket size of 1 mm to 3 mm in the front-to-back direction at the socket inlet.

[0036] According to an optional embodiment of this application, the socket structure has a socket size of 0.4 mm to 0.8 mm in the front-to-back direction at the socket end.

[0037] According to an optional embodiment of this application, the length of the retaining edge in the left-right direction is more than 50% of the length of the rear cover plate.

[0038] According to an optional embodiment of this application, in the assembled state, the left and right ends of the upper edge of the rear cover plate are not blocked by the retaining edge.

[0039] This makes it easier to install the rear cover and prevents deformation of the edge. Attached Figure Description

[0059] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application.

[0060] Figure 1 An example of the refrigerator of this application is shown in an exploded perspective view. This is a view of the rear of the refrigerator from the side and rear. The refrigerator includes a compressor 1 for compressing the refrigerant. The refrigerator has a compressor housing 2 to house the compressor 1. The compressor housing 2 has a rearward opening to house the compressor 1. The refrigerator also has a rear cover 3. After the compressor 1 is installed into the compressor housing 2, the rearward opening of the compressor housing 2 is sealed by the rear cover 3.

[0061] In this application, a socket structure 4 is provided for installing the rear cover plate 3, and the upper edge 30 of the cover plate 3 is adapted to insert the socket structure 4 from bottom to top.

[0062] Figure 2 The illustration shows a first example of the socket structure 4 of the refrigerator of this application.

[0063] like Figure 2 As shown, the socket structure 4 includes a retaining edge 40 adapted to block the upper edge 30 of the cover plate behind it.

[0064] In particular, the following technical effects can be achieved through the above method: the screw fixing block on the upper edge 30 of the cover plate 6 for fixing the rear cover plate 3 is eliminated; the insulation material 9 (see...) is not affected. Figure 4The foam layer is composed of a flange 40; the insertion structure 4 can be realized with a simple structure through the flange 40; the installation of the back cover 3 is simplified.

[0065] For example, along the extension direction of the flange 40 perpendicular to the left-right direction 92, the flange 40 has a dimension of less than 15 mm. That is, the flange 40 is very narrow in projection along the left-right direction 92.

[0066] For example, such as Figure 1 and Figure 2 As shown, the refrigerator includes an outer shell covered with insulation material 9. The outer shell includes a back panel 5, a bottom panel 6, and side panels 7 that are in contact with the insulation material 9. The back panel 5 is located above the rear cover 3. The bottom panel 6 retracts upward at the rear to form a compressor housing 2. The side panels 7 laterally cover the compressor housing 2. For example, as shown... Figure 1 As shown, the refrigerator may also include a compartment bottom plate 20 to enclose the lower side of the compressor compartment 2.

[0067] exist Figure 2 In this example, along an upward direction, the inner side 400 of the flange 40 facing the upper edge 30 of the cover plate extends obliquely forward. This results in: See [link to previous section] Figure 2 Along the front-to-back direction 91, the socket structure 4 has a larger socket size at the socket inlet and a smaller socket size at the socket outlet. This allows the rear cover plate 3 to be in an inclined position when inserting the socket structure 4 to facilitate insertion, and only to be converted to a vertical position after being inserted to the socket outlet.

[0068] To realize the socket structure 4, in addition to the rear retaining edge 40, the socket structure 4 also includes a support part 41. In the assembled state, the support part 41 supports the rear cover plate 3 in front of the rear cover plate 3. That is, the rear cover plate 3 is sandwiched between the support part 41 and the retaining edge 40, thereby restricting the movement of the rear cover plate 3 in the front-rear direction 91.

[0069] The support portion 41 can in particular support the upper edge 30 of the cover plate of the rear cover plate 3, and thus oppose the retaining edge 40. However, it is also theoretically possible that, instead of the upper edge 30 of the cover plate, the support portion 41 supports a lower area of ​​the rear cover plate 3.

[0070] For example, such as Figure 2 As shown, the support portion 41 includes a first support portion 411 formed by the base plate 6, which is adapted to support the upper edge 30 of the cover plate 3. Exemplarily, the first support portion 411 has a vertical first support surface 413 for supporting the upper edge 30 of the cover plate.

[0071] Figure 3 The side panel 7 is shown schematically in a partial perspective view.

[0072] For example, such as Figure 2 and Figure 3 As shown, the support portion 41 includes a second support portion 412 formed by the flange 70 of the side plate 7.

[0073] To further secure the rear cover 3, the refrigerator may also include a lower fixing structure 8 for fixing the lower part of the rear cover 3. The lower fixing structure 8 is used to fix the lower part of the rear cover 3. The lower fixing structure 8 needs to at least restrict the downward movement of the rear cover 3. The lower fixing structure 8 is particularly detachable.

[0074] For secure fixing, the lower fixing structure 8 is secured using screws 80. Therefore, the lower fixing structure 8 may include a cover plate through-hole 31 located in the lower part of the rear cover plate 3. Furthermore, see... Figure 2 and Figure 3 The lower fixing structure 8 also includes a flanged through hole 71 on the flange 70 of the side plate 7 and a plastic reinforcing member 72 accommodated by the side plate 7. The rear cover plate 3 is fixed by screws 80 through the cover plate through hole 31 and the flanged through hole 71 and screwed into the plastic reinforcing member 72.

[0075] Instead of fixing with screws 80, it is conceivable that the lower fixing structure 8 can be fixed in other ways, such as by locking or snap-fit.

[0076] For example, such as Figure 2 As shown, the insertion structure 4 is located between the back plate 5 and the bottom plate 6.

[0077] For example, such as Figure 2 As shown, the back panel 5 includes a back panel body 50 and a bent portion 43 at the lower end of the back panel body 50, the bent portion 43 forming a retaining edge 40. Figure 2 In the middle, the bent part 43 bends obliquely backward relative to the back panel body 50.

[0078] Figure 4 A second example of the socket structure 4 is shown in a partial schematic diagram. Here, the insulation material 9 is identified by a cross line. The insulation material 9 forms a foam layer between the inner liner and the outer shell of the refrigerator.

[0079] See Figure 4 In existing designs, screw fixing blocks are attached to the base plate 6 in the area of ​​the insulation material 9 for screwing in screws used to secure the upper edge 30 of the rear cover plate 3. The design of this application eliminates the need for these screw fixing blocks.

[0080] See Figure 4For example, along the front-rear direction 91, the socket size of the socket structure 4 at the socket inlet is 1 to 3 mm, especially 2 mm, and the socket size of the socket structure 4 at the socket end is 0.4 to 0.8 mm, especially 0.6 mm. The socket size of the socket structure 4 at the socket end can be consistent with, or slightly larger than or slightly smaller than, the size of the upper edge 30 of the cover plate 3.

[0081] For example, such as Figure 4 As shown, the insertion structure 4 may include an upper stop 42, which is adapted to block the upper edge 30 of the rear cover 3 from above. This restricts the upward movement of the rear cover 3.

[0082] For example, such as Figure 4 As shown, viewed along the front-rear direction 91, the bottom plate 6 extends to the front of the back plate body 50 and overlaps with the back plate body 50 along the front-rear direction 91 of the refrigerator, so as to prevent the insulation material 9 from leaking out through the gap between the bottom plate 6 and the back plate 5 during foaming.

[0083] For example, such as Figure 4 As shown, the bending portion 43 includes a first section 44 that bends rearward relative to the back panel body 50 and a second section 45 that bends downward relative to the first section 44, the second section 45 forming a retaining edge 40. The first section 44 forms an upper stop 42 in particular.

[0084] For example, such as Figure 4 As shown, the second segment 45 bends diagonally downward relative to the first segment 44.

[0085] To increase strength and remove sharp edges, for example, such as Figure 4 As shown, the free end of the flange 40 away from the rear cover plate 3 is provided with a stacked edge structure 401. For aesthetic purposes, the stacked edge structure 401 is an inner overlapping structure 401.

[0086] Figure 5 A third example of the socket structure 4 is schematically shown. Here, the second segment 45 is bent vertically downward relative to the first segment 44.

[0087] Figure 6 The fourth example of socket structure 4 is illustrated schematically.

[0088] Figure 7 The fifth example of socket structure 4 is illustrated schematically.

[0089] exist Figure 6 and Figure 7 In this example, the base plate 6 forms the insertion structure 4. Here, the base plate 6 includes a base plate body 60 and a bent portion 43 at the upper end of the base plate body 60, the bent portion 43 forming a retaining edge 40.

[0090] exist Figure 6 In the middle section, the bent portion 43 includes a first section 44 that bends rearward relative to the base plate body 60 and a second section 45 that bends downward relative to the first section 44, the second section 45 forming a retaining edge 40. The first section 44 forms an upper stop 42. The second section 45 bends obliquely downward relative to the first section 44.

[0091] exist Figure 7 In the middle, the upper edge of the base plate 6 is bent diagonally backward and downward.

[0092] Figure 8 An example of the retaining edge 40 is shown schematically in a partial rear view of the refrigerator.

[0093] For example, such as Figure 8 As shown, along the left-right direction 92, the length of the retaining edge 40 is more than 50% of the length of the rear cover plate 3. The retaining edge 40 is relatively narrow in the vertical direction. By increasing the length of the retaining edge 40 along the left-right direction 92, the force on the retaining edge 40 can be distributed, thereby ensuring that the retaining edge 40 does not deform.

[0094] Furthermore, for example, such as Figure 8 As shown, in the assembled state, the left and right ends of the upper edge 30 of the rear cover plate 3 are not blocked by the retaining edge 40.

[0095] exist Figure 8 The image schematically shows a centrally located retaining edge 40. It is clearly theoretically possible to have more than two retaining edges 40 separated by a left-right direction 92.

[0096] In the description of this embodiment, terms such as "up," "down," "left," "right," "front," and "back" are based on the normal usage posture of the refrigerator. When the refrigerator is used upright on the ground, in conventional terms, the side where the refrigerator door is located is "front," the ground is "down," and other orientations are determined accordingly. When the posture of the refrigerator changes, the meanings of these terms also change accordingly.

Those skilled in the art can also conceive of simple variations in the dimensions, quantity, position, shape, and interrelationships of these elements without departing from the scope of protection of this application.

[0098] In the accompanying drawings, there are multiple elements that have the same function. Sometimes only some of them are labeled as examples, but those skilled in the art can identify the other elements that have the same function without any doubt by the similarity between the shapes of these elements.
