Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and specifically provides a door seal, a freezing and refrigeration equipment, and an injection mold. Background Technology

[0002] Existing refrigeration and freezing equipment (such as refrigerators, freezers, freezers, etc.) are generally equipped with door seals to ensure their airtightness and prevent temperature cross-contamination between the inside and outside, which would affect the refrigeration effect of the equipment.

[0003] Existing refrigeration and freezing equipment generally consists of a cabinet and a door. The cabinet defines a storage compartment for containing goods. The door is pivotally connected to the cabinet to open and close the storage compartment. Door seals are typically installed on the door so that they separate from and come into contact with the cabinet as the door opens and closes the storage compartment. When in contact with the cabinet, the door seals are distributed between the door and the cabinet, thus achieving a seal between them.

[0004] Existing door seals typically include multiple air pockets to reduce the loss of cold air from the refrigeration unit by allowing the poorly conductive air inside the air pockets to pass through. Furthermore, one of the multiple air pockets is usually a magnetic strip air pocket, which contains a magnetic strip to attract the door seal to the cabinet.

[0005] However, due to the presence of the magnetic strip air bladder, there is generally a concave and narrow strip groove between the air bladders on the outer side of the door seal. Therefore, a thin sheet with a small thickness is required on the injection mold of the door seal to define this strip groove. This not only increases the processing difficulty of the injection mold, but also, because of its small thickness, the thin sheet has poor structural strength and is prone to deformation, thus affecting the injection molding quality of the door seal and resulting in a low yield rate. Utility Model Content

[0006] One objective of this invention is to solve the problem that the outer side of existing door seals has a concave and narrow strip groove, resulting in a low yield rate for injection molding.

[0007] To achieve the above objectives, this utility model provides a door seal in a first aspect, applicable to refrigeration and freezing equipment, comprising:

[0008] A fixing part is used to fix the door seal to the door of the refrigeration equipment;

[0009] An airbag is used to abut against the cabinet of the refrigeration equipment so that the door seal seals the cabinet and the door.

[0010] The airbag portion includes:

[0011] A magnetic stripe airbag is used to hold a magnetic stripe. The wall of the magnetic stripe airbag away from the fixing part is used to abut against the box body and is referred to as the abutting wall. The other walls of the magnetic stripe airbag are referred to as the grooved walls.

[0012] An airbag is used to wrap the grooved bladder wall to prevent the grooved bladder wall from contacting the air outside the refrigeration equipment. The airbag includes an outer bladder wall that contacts the air outside the refrigeration equipment, and the outer bladder wall protrudes in a direction away from the grooved bladder wall.

[0013] Optionally, the outer sac wall protrudes in a conical shape in a direction away from the groove-shaped sac wall.

[0014] Optionally, at least one deformation guiding structure is provided on the outer capsule wall to ensure that the outer capsule wall is always conical.

[0015] Optionally, the deformation guiding structure is a groove provided on the inner side of the outer bladder wall; and / or, the deformation guiding structure is provided at one bend of the outer bladder wall away from the grooved bladder wall and at two bends near the grooved bladder wall.

[0016] Optionally, the encapsulating airbag is provided with a partition wall to divide the encapsulating airbag into an outer airbag and an inner airbag. The outer airbag encapsulates a portion of the grooved bladder wall, and at least a portion of the outer airbag is in contact with the air outside the refrigeration equipment. The inner airbag encapsulates another portion of the grooved bladder wall, and at least a portion of the inner airbag is in contact with the air inside the refrigeration equipment.

[0017] Optionally, the partition wall protrudes from the outer airbag to the inner airbag and can abut against the wall of the inner airbag when the door is closed, so as to divide the inner airbag into two airbags.

[0018] Optionally, the grooved capsule wall is U-shaped.

[0019] In a second aspect, this utility model provides a freezing and refrigeration device, comprising:

[0020] The container is designed with a storage compartment.

[0021] A door body for opening and concealing the storage compartment, the door body comprising a door body, a door seal and a magnetic strip as described in any one of the first aspects, the door seal being installed on the side of the door body facing the box, and the magnetic strip being embedded in the magnetic strip airbag.

[0022] Optionally, the refrigeration equipment is a refrigerator, freezer, or freezer.

[0023] In a third aspect, this utility model provides an injection mold defining an injection cavity, the injection cavity being adapted to the door seal as described in any one of the first aspects to define the shape of the cross-section of the door seal.

[0024] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by configuring a wrapping airbag for the airbag portion of the door seal and having the wrapping airbag wrap around the grooved bladder wall, the grooved bladder wall is prevented from contacting the air outside the refrigeration equipment when the door of the refrigeration equipment is closed, thus reducing the amount of cold exposure at the magnetic strip airbag of the door seal. Simultaneously, by making the outer bladder wall of the wrapping airbag, which is in contact with the outside air, bulge away from the grooved bladder wall, the formation of a concave strip groove on the outer bladder wall of the wrapping airbag is avoided, thereby avoiding the need to set a thin sheet corresponding to the strip groove on the injection mold of the door seal, and thus improving the yield rate during door seal injection molding.

[0025] Furthermore, by making the outer wall of the airbag protrude into a cone shape, it not only facilitates the processing of the injection mold, but also avoids the outer wall of the airbag from contacting the magnetic strip airbag, thus reducing the amount of cold air exposed at the magnetic strip airbag of the door seal.

[0026] Furthermore, by setting at least one deformation guiding structure on the outer wall of the airbag, the outer wall is always conical, ensuring that the outer wall will never come into contact with the magnetic strip airbag during the opening and closing of the door.

[0027] Other beneficial effects of this utility model will be described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand the improvement purpose, features and advantages of this utility model. Attached Figure Description

[0043] like Figure 1 As shown, the door seal 100 of this utility model is applicable to refrigeration equipment 001, which can be a refrigerator, freezer, freezer, etc.

[0044] like Figure 1 As shown, the refrigeration and freezing equipment 001 of this utility model includes a cabinet 200 and a door 300. The cabinet 200 defines a storage compartment 201, and the door 300 is used to open and cover the storage compartment 201. A door seal 100 is provided on the side of the door body 310 facing the cabinet 200, and the door seal 100 can abut against the side of the cabinet 200 facing the door body 310.

[0045] The door 300 and the box 200 can be pivotally connected together via a pivot or hinge.

[0046] It should be noted that the refrigeration and freezing equipment 001 of this utility model is not limited to... Figure 1 The structure shown can be any other feasible structure. For example, a double-door structure, a T-shaped door structure, etc.

[0047] from Figure 1 As can be seen, the door 300 includes a door body 310 and a door seal 100 installed on the door body 310, and the door seal 100 is located on the side of the door body 310 facing the box 200.

[0048] The following reference Figures 2 to 4 The door seal 100 in some embodiments of this utility model will be described in detail below.

[0049] like Figures 2 to 4 As shown, in some embodiments of this utility model, the door seal 100 includes a fixing part 110 and an airbag part 120.

[0050] The fixing part 110 is used to fix the door seal 100 to the door body 300 of the refrigeration equipment 001.

[0051] Specifically, a fixing hook 111 is provided on the fixing part 110. A slot (not shown in the figure) adapted to the fixing part 110 is provided on the door body 310, and a fixing groove (not shown in the figure) adapted to the fixing hook 111 is provided on the side wall of the slot. When the fixing part 110 is inserted into the slot on the door body 310, the fixing hook 111 hooks into the fixing groove, thereby fixing the door seal 100 to the door body 310.

[0052] The airbag 120 is used to abut against the cabinet 200 of the refrigeration equipment 001 so that the door seal 100 seals the cabinet 200 and the door 300.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the airbag part 120 includes a magnetic strip airbag 121 and a wrapping airbag 122.

[0054] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, the magnetic strip airbag 121 is used to accommodate the magnetic strip 320, the wall of the magnetic strip airbag 121 away from the fixing part 110 is used to abut against the box body 200 and is referred to as the abutting wall 1211, and the other walls of the magnetic strip airbag 121 are referred to as the grooved wall 1212.

[0055] When the door 300 is closed, the abutting wall 1211 of the magnetic strip airbag 121 abuts against the box 200, and at the same time the magnetic strip 320 presses the abutting wall 1211 against the box 200.

[0056] from Figure 3 and Figure 4 As can be seen from the above, in some embodiments of this utility model, the grooved bladder wall 1212 is U-shaped so that the magnetic strip airbag 121 is a flat structure as a whole, thereby reducing the thickness of the airbag part 120.

[0057] In addition, in other embodiments of this utility model, those skilled in the art can also set the grooved bladder wall 1212 to other feasible structures as needed, such as C-shaped, semi-circular, triangular, etc.

[0058] In some embodiments of this invention, the magnetic strip 320 may be a rubber magnetic strip. The magnetic strip 320 may also include a strip-shaped substrate (e.g., a rubber strip) and a plurality of magnets uniformly distributed on the strip-shaped substrate.

[0059] like Figure 3 and Figure 4As shown, in some embodiments of this utility model, the airbag 122 wraps around the grooved bladder wall 1212 to prevent the grooved bladder wall 1212 from contacting the air outside the refrigeration equipment 001 when the door 300 is closed. Furthermore, the airbag 122 includes an outer bladder wall 1221 that contacts the air outside the refrigeration equipment 001, and the outer bladder wall 1221 protrudes in a direction away from the grooved bladder wall 1212.

[0060] Those skilled in the art will understand that by configuring a wrapping airbag 122 for the airbag portion 120 of the door seal 100, and by having the wrapping airbag 122 wrap around the grooved airbag wall 1212, the grooved airbag wall 1212 is prevented from contacting the air outside the refrigeration equipment 001 when the door 300 of the refrigeration equipment 001 is closed, thus reducing the amount of cold exposure at the magnetic strip airbag 121 of the door seal 100. Simultaneously, by making the outer airbag wall 1221 of the wrapping airbag 122 bulge away from the grooved airbag wall 1212, the formation of a concave groove on the outer airbag wall 1221 of the wrapping airbag 122 is avoided, thereby preventing the formation of a concave groove in the injection mold 400 (e.g., the door seal 100). Figure 5 As shown, thin sheets corresponding to the strip grooves are set on the door seal 100, thereby improving the yield of the door seal 100 during injection molding.

[0061] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the outer wall 1221 of the airbag 122 protrudes into a cone shape in the direction away from the grooved wall 1212. In this way, not only is it convenient to process the injection mold 400, but it also avoids the outer wall 1221 from contacting the magnetic strip airbag 121, thereby reducing the amount of cold air exposed at the magnetic strip airbag 121 of the door seal 100.

[0062] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, at least one deformation guiding structure 12211 is provided on the outer bladder wall 1221 to ensure that the outer bladder wall 1221 is always conical. In this way, the outer bladder wall 1221 is always conical, ensuring that the outer bladder wall 1221 will never come into contact with the magnetic strip airbag 121 during the opening and closing of the door 300.

[0063] from Figure 3 and Figure 4 As can be seen from the above, in some embodiments of this utility model, the deformation guiding structure 12211 is a groove provided on the inner side of the outer bladder wall 1221. And / or, the deformation guiding structure 12211 is provided at one bend of the outer bladder wall 1221 away from the grooved bladder wall 1212 and at two bends near the grooved bladder wall 1212.

[0064] In addition, in other embodiments of this utility model, those skilled in the art can also set the deformation guiding structure 12211 to any other feasible number as needed, for example, the deformation guiding structure 12211 is provided only at the two bends near the grooved bladder wall 1212.

[0065] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a partition wall 123 is provided inside the wrapping airbag 122 to divide the wrapping airbag 122 into an outer airbag 1222 and an inner airbag 1223.

[0066] from Figure 3 and Figure 4 As can be seen, the outer airbag 1222 encloses a portion of the grooved bladder wall 1212, and at least a portion of the outer airbag 1222 is in contact with the air outside the refrigeration equipment 001.

[0067] from Figure 3 and Figure 4 It can also be seen that the inner air bladder 1223 encloses another part of the grooved bladder wall 1212, and at least a part of the inner air bladder 1223 is in contact with the air inside the refrigeration equipment 001.

[0068] Those skilled in the art will understand that by dividing the airbag 122 into an outer airbag 1222 and an inner airbag 1223 by the partition wall 123, and by ensuring that the outer airbag 1222 wraps around a portion of the grooved wall 1212 and contacts the air outside the refrigeration equipment 001, while the inner airbag 1223 wraps around the other portion of the grooved wall 1212 and contacts the air inside the refrigeration equipment 001, the cold energy inside the refrigeration equipment 001 can only be transferred outwards sequentially through the inner airbag 1223 and the outer airbag 1222. Therefore, compared to the method where the cold energy inside the refrigeration equipment 001 is transferred outwards through only one airbag, the door seal 100 of this invention effectively reduces the cold energy transfer efficiency, thereby improving the insulation effect of the door seal 100.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the partition wall 123 protrudes from the outer airbag 1222 to the inner airbag 1223, so that the partition wall 123 deforms towards the inner airbag 1223 when the door seal 100 is squeezed and deformed by the door body 300 and the box body 200, thereby avoiding the partition wall 123 interfering with the deformation of the door seal 100.

[0070] like Figure 3 and Figure 4As shown, in some embodiments of this utility model, one side of the partition wall 123 is connected to the grooved bladder wall 1212; the other side of the partition wall 123 is connected to the encapsulating airbag 122 and aligned with the fixing part 110, so that the partition wall 123 deforms when the magnetic strip airbag 121 approaches the fixing part 110.

[0071] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, in the width direction of the magnetic strip airbag 121, the partition wall 123 is located on the side of the grooved bladder wall 1212 close to the inner airbag 1223, so as to prevent the partition wall 123 from being clamped by the grooved bladder wall 1212 and the bladder wall that wraps the airbag 122.

[0072] Continue reading Figure 3 and Figure 4 In some embodiments of this utility model, the portion of the partition wall 123 that protrudes into the inner airbag 1223 can abut against the wall of the inner airbag 1223 when the door 300 is closed, so as to divide the inner airbag 1223 into two airbags.

[0073] Those skilled in the art will understand that by making the portion of the partition wall 123 protrude into the inner airbag 1223 and abut against the wall of the inner airbag 1223 when the door 300 is closed, the inner airbag 1223 is divided into two airbags, thereby further improving the heat preservation effect of the door seal 100.

[0074] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the door seal 100 further includes a plurality of liner wings 130.

[0075] Specifically, Figure 3 A liner 130 is provided on the right side of the top of the middle fixing part 110. After the door seal 100 is installed on the door body 310, the liner 130 abuts against the side of the door body 310 near the airbag part 120 to prevent dust from entering the slot on the door body 310 used to fix the fixing part 110.

[0076] Accordingly, Figure 3 A liner 130 is provided on the left side of the bottom wall of the inner and outer airbags 1222. After the door seal 100 is installed on the door body 310, the liner 130 abuts against the side of the door body 310 near the airbag part 120 to prevent dust from entering the slot on the door body 310 used to fix the fixing part 110.

[0077] Continue reading Figure 3 A liner 130 is provided on the right side of the right side wall of the inner airbag 1223. When the door 300 is closed, the liner 130 abuts against the side of the door body 310 near the airbag part 120 to block the cold air inside the refrigeration equipment 001.

[0078] In this invention, the door seal 100 can be integrally manufactured using an extrusion process. The material of the door seal 100 may include at least one of polyvinyl chloride, silicone, rubber, acrylonitrile-butadiene-styrene copolymer, and thermoplastic elastomer.

[0079] Furthermore, although not explicitly shown in the figures, in some embodiments of this utility model, a door seal 100 is provided at each of the four edges (top, bottom, left, right) on the side of the door 300 facing the box 200, forming a rectangular frame to ensure that the door seal 100 seals the door 300 and the box 200.

[0080] It should be noted that installing the door seal 100 onto the door body 300 is a common technique in the field and is well known to those skilled in the art, so it will not be described in detail here.

[0081] Furthermore, in this utility model, the door body 300 also includes a magnetic strip 320. That is, the magnetic strip 320 is inserted into the magnetic strip airbag 121 before the door seal 100 is installed on the door body 310.

[0082] like Figure 5 As shown, the present invention also provides an injection mold 400, which defines an injection cavity 401, which is adapted to the door seal 100 described in any of the preceding embodiments to define the shape of the cross-section of the door seal 100.

[0083] from Figure 5 As can be seen, the injection mold 400 in this utility model does not have a thin sheet structure with a small thickness, which avoids the injection mold 400 from deforming during the injection molding of the door seal 100 due to the thin sheet structure inside, thus affecting the injection molding quality of the door seal 100.

[0084] It should be noted that, in the description of this utility model, the ratio of the thickness of the sheet to its length extending inward from the peripheral wall of the injection cavity 401 is greater than 2.5.

[0085] Continue reading Figure 5 The injection mold 400 also has at least one feed channel (such as...) Figure 5 (As shown by the dashed line in the middle), the raw material for injection molding door seal 100 is injected into injection cavity 401 through the feeding channel.

[0086] Based on the foregoing description, those skilled in the art will understand that the present invention, by configuring a wrapping airbag 122 on the airbag portion 120 of the door seal 100, and by having the wrapping airbag 122 wrap the grooved bladder wall 1212, and by having the outer bladder wall 1221 of the wrapping airbag 122 protrude in a direction away from the grooved bladder wall 1212, avoids the formation of a concave strip groove on the outer bladder wall 1221 of the wrapping airbag 122, thereby avoiding the need to set a thin sheet corresponding to the strip groove on the injection mold 400 of the door seal 100, and thus improving the yield of the door seal 100 during injection molding.

[0087] The technical solution of this utility model has been described in conjunction with several embodiments above. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is not limited to these specific embodiments. Without departing from the technical principles of this utility model, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this utility model will fall within the protection scope of this utility model.

[0088] Finally, it should be noted that in this invention, the term "connection" refers to fluid communication, allowing fluid (e.g., air, liquid) to flow between two interconnected entities. Furthermore, this "connection" can be either a leak-free flow of fluid between two interconnected entities, or a flow with slight leakage between two interconnected entities.
