Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] Most of the doors of refrigerators currently on the market are flip-open and flip-closed. When using the refrigerator, the user drives the door to rotate relative to the refrigerator body, thereby opening the refrigerator to take out and put in items.

[0003] In order to facilitate the opening and closing of the refrigerator door, a handle with an inwardly concave buckle is provided on the refrigerator door, and a handle installation opening is correspondingly provided on the door shell of the refrigerator door. When producing the refrigerator door, after the handle is installed in the handle installation opening of the door shell, in order to prevent the foam material of the door body from leaking, sponge is used to seal the joint between the handle and the handle installation opening of the door shell; at the same time, during the transportation of the door shell, tape is used to fix the handle to the door shell from the outside to prevent the handle from falling off. The existing handle installation structure of the refrigerator door requires a large amount of sponge and tape, and the sponge and tape need to be applied manually, which is inefficient and cannot guarantee consistency. It requires high proficiency of employees, and when the sponge and tape are not sealed firmly, it may cause leakage and misalignment of the handle, resulting in rework and scrapping, affecting normal use by users.

[0004] At the same time, for large-sized doors, the handle installation needs to be placed at the door shell opening, where the door shell strength is relatively weak. When used in a low-temperature environment, the door shell may deform, and a reinforcing iron needs to be placed at the handle to strengthen the door body. This reinforcing iron needs to be attached to the door shell using double-sided tape, which has high labor costs and poor adhesion. When the door shell is transported, the reinforcing iron is easily displaced and loses its function of reinforcing the door shell.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In view of the problems pointed out in the background technology, the utility model provides a refrigerator, wherein the door handle and the handle installation opening on the door shell are reliably sealed, the handle is firmly fixed, and the reinforcing member can effectively ensure the reinforcing effect of the door shell at the handle installation location.

[0007] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0008] In some embodiments of the present application, a refrigerator is provided, including a door body and a box body, wherein the door body includes:

[0009] A door shell, wherein the door shell is provided with a handle installation opening communicated with the inner space of the door body;

[0010] A handle assembly comprises a handle and a reinforcement member, wherein the handle comprises a buckle portion and a circumferential limiting portion connected to the periphery of the buckle portion, the buckle portion is recessed and embedded in the handle mounting opening, a first clamping member is formed on the inner wall of the buckle portion, and the circumferential limiting portion abuts against the outer wall of the door shell outside the handle mounting opening; the reinforcement member is located inside the door body of the refrigerator, a second clamping member is formed on the reinforcement member, the second clamping member is clamped with the first clamping member, the reinforcement member abuts against the inner wall of the door shell outside the handle mounting opening, an annular sealing member is provided on the reinforcement member, and the annular sealing member interference clamp is arranged between the reinforcement member and the inner wall of the door shell outside the handle mounting opening.

[0011] The refrigerator in the embodiment of the present application has a handle assembly of the door body including a handle and a reinforcement, which are connected by a first clamping piece on the handle buckle part and a second clamping piece on the reinforcement to fix the handle assembly and prevent it from loosening, without the need for additional fixing with tape; at the same time, the circumferential limiting parts of the reinforcement and the handle respectively abut against the door shell outside the handle installation opening from the inside and outside of the door shell outside the handle installation opening, and an annular sealing member is arranged on the reinforcement, and the annular sealing member interference clamp is arranged between the reinforcement and the inner wall of the door shell outside the handle installation opening to ensure the sealing of the handle installation position, effectively reducing the situation of foaming leakage; the handle also fixes the reinforcement to fix its position in the door body, which can effectively play a role in strengthening the door shell.

[0012] In some embodiments of the present application, the reinforcement member includes a foaming accommodating cavity for accommodating a foaming material, the foaming accommodating cavity is open at least to the side where the handle is located, and a foam injection hole is formed on the cavity wall of the foaming accommodating cavity;

[0013] The handle portion is located in the foaming accommodating cavity, and an outward-turned abutting surface is formed on the opening edge of the foaming accommodating cavity, and the abutting surface abuts against the inner wall of the door shell outside the handle installation opening.

[0014] Through the above structure, after the handle assembly is installed in place, when the door body is foamed, the foaming material can enter the foaming accommodating cavity through the foaming hole, and finally the reinforcement is buried in the foaming layer of the door body, thereby ensuring the thermal insulation effect of the door body; and the foaming material can further push the reinforcement to support against the inner wall of the door shell outside the handle installation port, thereby further improving the reinforcement effect on the door shell.

[0015] In some embodiments of the present application, an annular seal positioning portion is formed on the abutment surface, the annular seal is pre-installed on the seal positioning portion, and the buckle portion is embedded in the foaming accommodating cavity through the seal positioning portion.

[0016] The annular seal can be assembled with the reinforcement in advance to ensure the consistency of the incoming materials and improve the assembly accuracy; the seal positioning part plays a positioning role in the installation of the annular seal, reducing the risk of displacement and dislocation of the annular seal, and there is no need to use double-sided tape, which greatly improves production efficiency.

[0017] In some embodiments of the present application, an annular sealing surface is formed on the periphery of the buckle portion, and a sealing protrusion extending or arranged along the circumference is formed on the inner wall of the seal positioning portion, and the sealing protrusion is sealed with the annular sealing surface.

[0018] Through the sealing cooperation between the annular sealing surface of the buckle part and the sealing protrusion on the inner wall of the seal positioning part, the gap between the outer circumference of the buckle part and the seal positioning part is minimized as much as possible, preventing the foaming material from flowing along the gap to the annular seal, thereby further improving the sealing of the handle installation point.

[0019] In some embodiments of the present application, a support arm is connected between the sealing positioning portion and the bottom wall of the foaming accommodating cavity to increase the structural strength of the reinforcement itself, thereby increasing its reinforcing effect on the door shell; a bubble flow outlet is formed between the support arm and the side wall of the foaming accommodating cavity to avoid the flow of foaming material, thereby avoiding the formation of a dead angle between the support arm and the side wall of the foaming accommodating cavity, thereby preventing the formation of hollowing in the foaming layer.

[0020] In some embodiments of the present application, the extension direction of the foaming accommodating cavity is parallel to the extension direction of the handle, and both ends of the foaming accommodating cavity are also open, that is, the two ends of the foaming accommodating cavity are not closed, which further facilitates the foaming material to enter the internal space of the reinforcement and improves the foaming effect and the thermal insulation effect of the door body.

[0021] In some embodiments of the present application, the first clamping member includes a clamping column, the clamping column protrudes toward the side where the reinforcement member is located along a direction perpendicular to the door shell outside the handle installation opening, and the second clamping member includes a clamping groove adapted to the shape of the clamping column, and the clamping column is clamped in the clamping groove;

[0022] The clamping column is a tapered column that tapers from its root to its free end. The root of the clamping column is interference fit with the slot opening of the clamping groove, the free end of the clamping column is clearance fit with the bottom of the clamping groove, and the middle part of the clamping column is transition fit with the middle part of the clamping groove.

[0023] By adopting the clamping column and clamping groove of this structural form, after the handle is installed in place in the handle installation opening, as the subsequent reinforcement is installed, the clamping column is gradually inserted into the clamping groove until the root of the clamping column is interference fit with the clamping groove. The clamping groove is deformed by extrusion and applies extrusion pressure to the clamping column, thereby fixing the handle and ensuring that the handle will not loosen during transportation. At the same time, according to the principle of action and reaction force, the handle also fixes the reinforcement to fix its position on the door body, which can effectively strengthen the door shell.

[0024] In some embodiments of the present application, the second clamping member protrudes toward the side where the handle is located, and the clamping groove extends toward the side where the handle is located in a direction perpendicular to the door shell outside the handle mounting opening; this can shorten the distance between the reinforcement member and the handle buckle part, which is beneficial to reducing the volume of the entire handle assembly, so as to reduce the occupation of the foaming space inside the door body.

[0025] The cross-section of the clamping column is trapezoidal, and the clamping groove corresponds to a trapezoidal groove, and the groove wall corresponding to the upper bottom of the trapezoid is open. The trapezoidal groove and the trapezoidal column have high matching stability, and the groove wall on one side of the clamping groove is open, which can provide deformation space for it, thereby facilitating the clamping of the clamping column and the clamping groove.

[0026] In some embodiments of the present application, two first clamping members are symmetrically arranged along the extension direction of the buckle portion, and two second clamping members are correspondingly arranged, and the open groove walls of the clamping grooves of the two second clamping members are opposite to each other to improve the clamping reliability.

[0027] In some embodiments of the present application, since the reinforcing member has a reliable reinforcing effect on the door shell, there is no need to use reinforcing iron as in the prior art, and the reinforcing member can be made of plastic, that is, the reinforcing member is an integrated injection molding structure, further reducing costs.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0054] In some embodiments of the present application, reference Figure 1 , a refrigerator is provided, which includes a cabinet body 2 and a door body 1.

[0055] A freezing chamber is formed inside the cabinet 2, and the top or front side of the cabinet 2 is open to form a loading and unloading port communicating with the freezing chamber.

[0056] One side of the door body 1 is the installation side, and the door body 1 is rotatably connected to the box body through the installation side. The other side of the door body 1 opposite to the installation side is the opening and closing side, and the door body 1 can open or close the access opening through the opening and closing side.

[0057] The door body 1 includes a door shell 200 and a door liner 300 disposed inside the door shell 200. Figure 2 Schematic diagram of the structure of the refrigerator door according to the embodiment. Figure 2 The door body 1 includes a door shell 200 constituting the outer surface of the door body 1, a door liner 300 arranged on the inner side of the door shell 200, and a handle assembly 100 arranged on the door shell 200. The door shell 200 and the door liner 300 surround the inner space of the door body, and the inner space of the door body is foamed to form a foam layer by foaming the foam material.

[0058] During the production process of the door body 1, after the door body 1 is assembled, a foaming material is injected into the internal space of the door body. The foaming material will expand rapidly and fill the internal space of the door body. After the foaming material is solidified, a foaming layer is formed. The foaming layer has the effect of heat preservation and heat insulation, which can reduce the heat exchange between the cold air in the cabinet body 2 and the outside through the door body 1, thereby improving the refrigeration effect of the refrigerator.

[0059] Figure 3 FIG. 1 is a schematic diagram of the structure of the refrigerator door after the handle assembly 100 is omitted according to the embodiment, referring to FIG. Figure 3 , while combining Figure 2 The door shell 200 is provided with a handle installation opening 210 which is connected with the inner space of the door body, and the handle assembly 100 is installed in the handle installation opening 210 .

[0060] In some embodiments of the present application, the refrigerator is a rectangular horizontal refrigerator, the door body 1 is located at the top of the box body, the rear side of the door body 1 is its installation side, and the front side is its opening and closing side. The handle installation opening 210 is arranged on the front side panel among the circumferential side panels of the door shell 200, and the handle assembly 100 is installed on the front side panel among the circumferential side panels of the door shell 200 to facilitate the user to open or close the door body 1 from the opening and closing side of the door body 1.

[0061] Of course, the refrigerator can also be a vertical refrigerator, with the door body 1 located at the front of the box body, the left side of the door body 1 being its installation side, and the right side being its opening and closing side, and the handle installation opening 210 being arranged on the right side panel in the circumferential side panel of the door shell 200, and the handle assembly 100 being installed on the right side panel in the circumferential side panel of the door shell 200.

[0062] Reference Figures 4 to 15 In some embodiments of the present application, the handle assembly 100 includes a handle 110 and a reinforcement 120, the handle 110 includes a handle portion 111 and a circumferential limiting portion 112 connected to the periphery of the handle portion 111, the handle portion 111 is recessed into the internal space of the door body and embedded in the handle mounting opening 210, a first clamping member 113 is formed on the inner wall of the handle portion 111 (the surface of the handle portion 111 facing the internal space of the door body is its inner wall, and the surface facing the outside is its outer wall), the circumferential limiting portion 112 abuts against the outer wall of the door shell 200 outside the handle mounting opening 210, and taking the case where the handle assembly 100 is installed on the front side panel among the circumferential side panels of the door shell 200 as an example, the circumferential limiting portion 112 is located on the outer side of the front side panel of the door shell 200 and abuts against the front side panel of the door shell 200.

[0063] The reinforcement member 120 is located inside the refrigerator door body 1, and a second clamping member 121 is formed thereon, and the second clamping member 121 is clamped with the first clamping member 113. The reinforcement member 120 abuts against the inner wall of the door shell 200 outside the handle installation opening 210. Taking the handle assembly 100 installed on the front side plate of the circumferential side plate of the door shell 200 as an example, the reinforcement member 120 is located inside the front side plate of the door shell 200 and abuts against the front side plate of the door shell 200. An annular seal 130 is provided on the reinforcement member 120, and the annular seal 130 interference clamp is arranged between the reinforcement member 120 and the inner wall of the door shell 200 outside the handle installation opening 210.

[0064] When assembling the handle assembly 100, take a processed door shell 200, install the handle 110 from the outside of the door shell 200 into the handle installation port 210 until its circumferential limit portion 112 abuts against the outer wall of the front side plate of the door shell 200, then take a reinforcement 120, align the second clip 121 with the first clip 113 from the inside of the door shell 200, and then install it until the second clip 121 is clamped with the first clip 113, and the reinforcement 120 abuts against the inner wall of the front side plate of the door shell 200.

[0065] The reinforcement 120 and the circumferential limiting portion 112 of the handle 110 respectively abut against the front side plate of the door shell 200 from the inner and outer sides of the front side plate of the door shell 200, and the two interact with each other. The reinforcement 120 ensures the fixation of the handle 110, so that the handle 110 will not get loose during transportation, and there is no need to use additional tape to fix it; at the same time, the handle 110 also fixes the reinforcement 120, so that the position of the reinforcement 120 in the door body 1 is fixed and the abutment force against the front side plate of the door shell 200, so that it can effectively play the role of strengthening the door shell 200.

[0066] An annular seal 130 is provided on the reinforcement 120 , and the annular seal 130 is interference-clamped between the reinforcement 120 and the inner wall of the door shell 200 outside the handle installation opening 210 to ensure the sealing of the installation position of the handle 110 and effectively reduce the situation of foaming leakage.

[0067] In some embodiments of the present application, Figure 6 , Figures 9 to 11 As shown, the circumferential limiting portion 112 is connected to a top positioning portion 115, and the top positioning portion 115 is bent and connected to the top of the circumferential limiting portion 112. When the handle 110 is installed on the door shell 200, the circumferential limiting portion 112 abuts against the outer wall of the door shell 200 outside the handle installation opening 210, specifically located on the outer wall of the front side plate of the door shell 200, and the top positioning portion 115 abuts against the top surface of the door shell 200, so that the top positioning portion 115 overlaps the top of the door body 1, ensuring that the handle 110 is stably fixed to the handle installation opening 210 of the door body 1.

[0068] In some embodiments of the present application, Figures 6 to 10As shown, the reinforcement 120 includes a foaming accommodating cavity 123, which is used to allow foaming material to enter and then accommodate the foaming material when the door body 1 is foaming. The foaming accommodating cavity 123 is open at least to the side where the handle 110 is located, and a foaming hole 124 is formed on the cavity wall of the foaming accommodating cavity 123.

[0069] The buckle portion 111 extends into the foam accommodating cavity 123 through the handle installation opening 210. The opening edge of the foam accommodating cavity 123 is formed with an outward-turned abutting surface 122. The abutting surface 122 abuts against the inner wall of the door shell 200 outside the handle installation opening 210, that is, abuts against the inner wall of the front side panel of the door shell 200, thereby realizing the abutment between the reinforcement 120 and the inner wall of the door shell 200 outside the handle installation opening 210.

[0070] Through the above structure, after the handle assembly 100 is installed in place, when the door body 1 is foamed, the foaming material can enter the foaming accommodating cavity 123 through the foaming hole 124, and finally the reinforcement 120 is buried in the foaming layer of the door body 1, thereby ensuring the thermal insulation effect of the door body 1; and the foaming material can further push the reinforcement 120 to support against the inner wall of the door shell 200 outside the handle installation port 210, thereby further improving the reinforcement effect on the door shell 200.

[0071] like Figure 7 , Fig.10 , Fig.14 and Fig.15 As shown, there are a plurality of bubble injection holes 124 which are spaced apart along the length direction of the reinforcement member 120 . The plurality of bubble injection holes 124 may be disposed on the bottom plate of the reinforcement member 120 (ie, the side plate opposite to the handle 110 ).

[0072] In some embodiments of the present application, the annular seal 130 is disposed on the reinforcement 120. Specifically, an annular seal positioning portion 125 is formed on the abutment surface 122, and the annular seal 130 is adapted to be pre-installed on the seal positioning portion 125. The buckle portion 111 is embedded in the foaming accommodating cavity 123 through the handle installation port 210 and the seal positioning portion 125 in sequence.

[0073] like Fig.14 and Fig.15 As shown, the seal positioning portion 125 is a circle of positioning bosses, which can be an integrally formed structure with the reinforcement member 120 , and the positioning bosses protrude from the abutting surface 122 of the reinforcement member 120 toward the side where the handle 110 is located.

[0074] The annular seal 130 can be a sponge. Before the reinforcement 120 is installed in the door shell 200, the annular seal 130 is pre-mounted on the seal positioning portion 125. When the reinforcement 120 is installed in place, the annular seal 130 is clamped between the abutment surface 122 of the reinforcement 120 and the inner wall of the door shell 200 outside the handle installation opening 210 to seal the gap between the handle installation opening 210 and the handle 110.

[0075] The annular seal 130 can be assembled into one with the reinforcement 120 in advance to ensure the consistency of the incoming materials and improve the assembly accuracy; the seal positioning portion 125 plays a positioning role in the installation of the annular seal 130, reducing the risk of displacement and dislocation of the annular seal 130, and there is no need to use double-sided tape, which greatly improves production efficiency.

[0076] In some embodiments of the present application, a ring-shaped sealing surface 114 is formed on the periphery of the buckle portion 111. Figure 6 and Fig.11 As shown, a sealing protrusion (not shown) extending or arranged along the circumference of the sealing member positioning portion 125 is formed on the inner wall of the sealing member positioning portion 125 , and the sealing protrusion is sealingly matched with the annular sealing surface 114 .

[0077] Through the sealing cooperation between the annular sealing surface 114 of the buckle part 111 and the sealing protrusion on the inner wall of the sealing positioning part 125, the gap between the outer circumference of the buckle part 111 and the sealing positioning part 125 is minimized as much as possible, thereby further improving the sealing performance of the installation place of the handle 110 and preventing the foaming material from flowing along the gap to the outside of the door handle 110 and the door shell 200 and causing leakage during the production process.

[0078] The sealing protrusion may be a circle of relatively small protrusions having a guiding slope, so that the annular sealing surface 114 of the buckle portion 111 can extend into the foaming accommodating cavity 123 through the sealing member positioning portion 125 under the guidance of the guiding slope.

[0079] In some embodiments of the present application, Fig.10 and Fig.14 As shown, a support arm 126 is connected between the sealing positioning portion 125 and the bottom wall of the foaming accommodating cavity 123 to improve the structural strength of the reinforcement 120 itself, thereby improving its reinforcing effect on the door shell 200; a bubble flow outlet 127 is formed between the support arm 126 and the side wall of the foaming accommodating cavity 123 to avoid the flow of foaming material, thereby avoiding the formation of a dead angle between the support arm 126 and the side wall of the foaming accommodating cavity 123, thereby preventing the formation of hollowing of the foaming layer.

[0080] like Figure 7 , Fig. 9 , Fig.10 and Fig.14As shown, in some embodiments of the present application, the extension direction of the foaming accommodating cavity 123 is parallel to the extension direction of the handle 110, and both ends of the foaming accommodating cavity 123 are also open, that is, the two ends of the foaming accommodating cavity 123 are not closed, which further facilitates the foaming material to enter the internal space of the reinforcement 120, thereby improving the foaming effect and the thermal insulation effect of the door body 1.

[0081] The cross section of the reinforcement member 120 is generally U-shaped with its opening facing the side where the handle 110 is located. The injection holes 124 are arranged on its bottom plate, and the abutment surfaces 122 are formed on the edges of its upper and lower side plates, which are folded upward and downward respectively.

[0082] like Figure 6 , Figure 8 , Fig.11 , Fig.12 , Fig.14 and Fig.15 As shown, in some embodiments of the present application, the first clamping member 113 includes a clamping column 1131, which protrudes toward the side where the reinforcement 120 is located along a direction perpendicular to the door shell 200 outside the handle mounting opening 210 (i.e., a direction perpendicular to the front side plate of the door shell 200), and the second clamping member 121 includes a clamping groove 1211 that is adapted to the shape of the clamping column 1131, and the clamping column 1131 is clamped in the clamping groove 1211.

[0083] The clamping column 1131 is a tapered column that tapers from its root to its free end. The root of the clamping column 1131 has an interference fit with the slot opening of the clamping groove 1211, the free end of the clamping column 1131 has a clearance fit with the bottom of the clamping groove 1211, and the middle part of the clamping column 1131 has a transition fit with the middle part of the clamping groove 1211.

[0084] By adopting the snap-in column 1131 and the snap-in groove 1211 of this structural form, after the handle 110 is installed in the handle installation opening 210, as the subsequent reinforcement 120 is installed, the snap-in column 1131 is gradually inserted into the snap-in groove 1211 until the root of the snap-in column 1131 is interference fit with the snap-in groove 1211. The snap-in groove 1211 is deformed by extrusion and applies extrusion force to the snap-in column 1131, thereby fixing the handle 110 and ensuring that the handle 110 will not loosen during transportation. At the same time, according to the principle of action and reaction force, the handle 110 also fixes the reinforcement 120, so that it is fixed in the position of the door body 1, which can effectively strengthen the door shell 200.

[0085] In some embodiments of the present application, the second snap-fit ​​component 121 protrudes toward the side where the handle 110 is located, and the snap-fit ​​groove 1211 extends toward the side where the handle 110 is located along a direction perpendicular to the door shell 200 outside the handle mounting opening 210 (i.e., a direction perpendicular to the front side plate of the door shell 200); this can shorten the distance between the reinforcement 120 and the handle buckle portion 111, which is beneficial to reducing the volume of the entire handle assembly 100, so as to reduce the occupation of the foaming space inside the door body 1.

[0086] In some embodiments of the present application, the cross-section of the clamping column 1131 is trapezoidal, the clamping groove 1211 corresponds to a trapezoidal groove, and the groove wall corresponding to the upper bottom of the trapezoid is open. The trapezoidal groove and the trapezoidal column have high matching stability. The groove wall on one side of the clamping groove 1211 is open, which can provide it with deformation space, thereby facilitating the clamping of the clamping column 1131 and the clamping groove 1211.

[0087] In some embodiments of the present application, the first clamping member 113 also includes a connecting portion 1132, a clamping column 1131 is formed on the connecting portion 1132, and the connecting portion 1132 is connected to the inner wall of the buckle portion 111. A gap 1133 is left between the connecting portion 1132 and the connecting portion 1132 of the buckle portion 111, which can avoid the formation of a dead angle between the connecting portion 1132 and the connecting portion 1132 of the buckle portion 111, thereby preventing the formation of a hollowing phenomenon in the foaming layer.

[0088] In some embodiments of the present application, two first clamping members 113 are symmetrically arranged along the extension direction of the buckle portion 111, and two second clamping members 121 are correspondingly arranged. The open groove walls of the clamping grooves 1211 of the two second clamping members 121 are opposite to each other to improve the clamping reliability.

[0089] Of course, the shapes of the first clamping member 113 and the second clamping member 121 may also be other compatible shapes, and the number thereof may also be other numbers, and no specific limitation is made here.

[0090] In some embodiments of the present application, since the reinforcement member 120 has a reliable reinforcing effect on the door shell 200, there is no need to use reinforcing iron as in the prior art. The reinforcement member 120 can be made of plastic, such as ABS, that is, the reinforcement member 120 is an integrated injection molding structure, which further reduces costs.

[0091] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0092] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
