Description

Technical Field

[0001] This invention relates to the field of refrigeration appliances, specifically to a refrigerator and a beam for the refrigerator. Background Technology

[0002] Multi-door refrigerators typically have a rotatable, sealing beam installed on each door to prevent cold air from escaping through the gap between the two doors. However, if there are significant manufacturing or assembly errors in the beam, a large gap can easily form between the end of the beam and the inner wall of the refrigerator liner after the two doors are closed. This can affect the refrigerator's insulation performance during use, and condensation can easily form at the door seals in the gap. Summary of the Invention

[0003] One of the objectives of this invention is to provide an improved refrigerator and a beam for the refrigerator, which can effectively improve at least one of the above-mentioned technical problems.

[0004] One embodiment of the present invention provides a refrigerator, which includes: a storage compartment having an inner wall;

[0005] For closing the first and second doors of the storage room; and a beam rotatably disposed on the first door, the beam having a receiving space for accommodating insulation material; the beam including an air block located at an end of the beam, the air block being located between the end and the inner wall when the first door is closed.

[0006] The installation of air barriers helps to reduce the flow of cold air from the end of the beam and the inner wall of the storage room opposite the end of the beam toward the door, thereby reducing the heat exchange between the inside and outside of the storage room and reducing the possibility of condensation.

[0007] Optionally, the air-blocking component may include an air-blocking portion, which may have at least one cavity located between the end and the inner wall. The space within the cavity enhances the heat insulation performance of the air-blocking component, thereby improving the refrigerator's performance.

[0008] Optionally, the cavity and the accommodating space are independent of each other.

[0009] Optionally, the air barrier may include a flexible cavity wall forming the cavity. A flexible cavity wall allows the air barrier to deform, which helps reduce the likelihood of interference between the air barrier and the refrigerator body, potentially causing damage such as the inability to close the refrigerator door or beams.

[0010] Preferably, the cavity wall can be made of an elastic material. This not only increases the deformability of the cavity wall, but also ensures that even if the air barrier of the door interferes with the refrigerator body during use, the cavity wall made of elastic material is not easily damaged or damages the refrigerator body.

[0011] Optionally, when the first door is closed, the cavity may be closed along the depth direction of the storage room.

[0012] Optionally, the cavity can be closed, and a closed cavity has a better heat insulation effect, and the heat insulation effect can be achieved by the gas (e.g., air) in the cavity.

[0013] Optionally, when the cavity is a closed cavity, it may be filled with an inert gas.

[0014] Optionally, the cavity can be configured to extend along the width direction of the beam and have a constant cross-section. This helps to improve the consistency of the air barrier's performance along the width direction of the beam, and also provides the possibility that the air barrier can be mass-produced using a one-piece molding process.

[0015] Optionally, when the first door is closed, the ratio of the width of the cavity along the depth direction of the storage compartment, or the sum of its widths, to the thickness of the beam along the depth direction of the storage compartment is not less than 1:2. This significantly improves the thermal insulation performance of the air barrier and also helps reduce the possibility of condensation in the refrigerator.

[0016] Optionally, the air barrier may include at least two cavities. The at least two cavities may be distributed back-to-back along the depth direction of the storage compartment when the first door is closed. Multiple cavities along the depth direction of the storage compartment reduce the heat exchange rate, thus enhancing the insulation effect of the air barrier.

[0017] Optionally, the air barrier includes an end face facing the inner wall when the first door is closed, and the end face may be a plane.

[0018] Optionally, the end face of the air barrier is parallel to the surface of the inner wall. This helps to control a relatively constant gap between the air barrier and the inner wall, and it is expected that the thermal insulation performance of the air barrier will be improved while ensuring the gap between the air barrier and the inner wall.

[0019] Optionally, the air barrier may include at least two cavities and partitions separating adjacent cavities, with at least one end of each partition connected to a cavity wall forming the outer surface of the air barrier. The partitions facilitate the stability of the cavity shape and enable mass production of air barriers comprising multiple cavities.

[0020] Optionally, the thickness of the partition wall can be set to be less than the thickness of the cavity wall constituting the outer surface of the air barrier.

[0021] Optionally, the thickness of the partition wall is no more than two-thirds of the thickness of the cavity wall constituting the outer surface of the air barrier. Such a thickness design helps to improve the flatness of the cavity wall of the air barrier and is relatively beneficial to the deformability of the air barrier portion.

[0022] Optionally, the air barrier may include at least two partitions, which are distributed back-to-back and parallel to each other along the depth direction of the storage compartment when the first door is closed. The partitions form multiple parallel cavities distributed back-to-back along the depth direction of the storage compartment, which helps to reduce the heat exchange rate between the cold air inside the storage compartment and the outside, and improves the heat insulation effect of the air barrier.

[0023] Optionally, the air barrier may include a rigid fixing part fixed to the end wall of the beam.

[0024] Optionally, the fixing part may be configured as part of the cavity wall.

[0025] Optionally, the fixing part can be plate-shaped, and / or the air barrier part can be flat. This helps to reduce the size of the air barrier along the length of the beam while still ensuring the thermal insulation performance of the air barrier in the depth direction of the storage compartment.

[0026] Optionally, the air barrier may include a neck extending from one side of the fixing part, and a main body extending from the neck towards the front and / or rear wall of the beam to form a hollow cavity. This is beneficial for increasing the size of the air barrier in the depth direction of the storage compartment, thereby improving the thermal insulation performance of the air barrier.

[0027] Optionally, the end wall of the end portion may have a groove located outside the receiving space, the groove opening toward the inner wall, and the air barrier includes a fixing portion received in the groove.

[0028] Optionally, the air blocking part can be attached to the bottom wall of the groove.

[0029] Optionally, the fixing part can be inserted and / or pasted to the end of the beam.

[0030] Optionally, the groove can be formed in a T-shaped cross-section.

[0031] Optionally, the air barrier may include a neck extending through the groove. Maximizing the air barrier portion helps improve the thermal insulation performance of the air barrier when the distance between the beam and the inner wall is limited.

[0032] Optionally, the beam may include a first housing portion and a second housing portion connected to define the receiving space, and the groove is at least partially located between the first housing portion and the second housing portion.

[0033] Optionally, the bottom wall of the groove may be formed by only one of the first housing portion and the second housing portion.

[0034] Optionally, the first housing portion includes a first receiving portion, and the second housing portion includes a second receiving portion; when the first housing portion and the second housing portion are connected, the first receiving portion and the second receiving portion at least partially overlap to form the groove, and the overlapping portion has a spacing in the length direction of the beam, and the fixing portion is at least partially clamped in the spacing.

[0035] Optionally, a gap may be present between the air barrier and the inner wall. This helps prevent or reduce interference between the beam and the refrigerator body during use.

[0036] Optionally, the gap is not less than 1 mm, and to ensure the heat insulation effect of the air barrier, the gap is preferably not greater than 5 mm. For example, the gap is between 2 and 3 mm.

[0037] Optionally, the side of the fixing part away from the air barrier part can be bonded to a portion of the beam.

[0038] Optionally, the fixing part may be provided with an insertion part with an inclined outer surface, the insertion part being inserted into the groove, and the inner wall of the groove having an inner wall surface that is inclined to fit the outer surface. This arrangement facilitates the installation of the fixing part.

[0039] Optionally, the fixing part and the air blocking part can be made of different materials.

[0040] Optionally, the fixing part and the air blocking part can be integrally formed, for example, by a soft and hard co-extrusion integral forming process.

[0041] Optionally, the refrigerator also has a guide component that guides the beam to flip when the first door is opened or closed.

[0042] Optionally, the beam may also include a front panel, with the air barrier and the front panel fixed to the beam in a non-contact manner. This arrangement reduces heat exchange between the air barrier and the front panel or heating components within the front panel.

[0043] Optionally, the end of the air barrier near the front wall of the beam does not extend beyond the front wall to prevent the beam from interfering with the side of the door when it rotates.

[0044] Another aspect of the present invention relates to a beam for a refrigerator, the beam being rotatably fixed to the door of the refrigerator, characterized in that the beam comprises: a housing having a receiving space for accommodating insulating material; and an air barrier fixed to one end of the housing.

[0045] This reduces the amount of cold air in the storage compartment flowing through the beams and the inner wall of the storage compartment towards the refrigerator door and exchanging heat with the outside, thus reducing the likelihood of condensation in the refrigerator.

[0046] Optionally, the air barrier includes an air blocking portion having at least one cavity located between the end and the inner wall, the cavity and the receiving space being independent of each other.

[0047] Optionally, the air barrier may include a fixing part fixed to the housing and a flexible air barrier located outside the housing.

[0048] Optionally, the end of the housing may have a groove located outside the receiving space, the groove opening toward the inner wall of the refrigerator, and the air barrier includes a fixing portion received in the groove. Attached Figure Description

[0056] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but these are not intended to limit the scope of the present invention.

[0057] like Figure 1-2 As shown, in this embodiment, the refrigerator 100 includes a cabinet 101 having a storage compartment 102. The storage compartment 102 has an inner wall 103.

[0058] Refrigerator 100 includes a first door 107 and a second door 108 for closing the storage compartment 102.

[0059] A rotatable beam 105 is provided between the first door 107 and the second door 108 of the closed storage room 102. When the first door 107 and the second door 108 are closed, the beam 105 overlaps with the sealing strips 112 of the first door 107 and the second door 108, and seals the gap between the first door 107 and the second door 108.

[0060] The beam 105 is rotatably fixed to the first door 107. When the first door 107 is opened from the closed position or closed from the open position, the beam 105 rotates relative to the first door 107 under the action of the guide mechanism 106 between the beam 105 and the box body 101.

[0061] Optionally, the guiding mechanism 106 may include a guiding member located at one end of the beam 105 and a mating guiding portion located on the housing 101. The mating guiding portion may be located on the opposite inner wall at the other end of the beam.

[0062] The beam 105 may include a housing 300 having a receiving space 109 for accommodating the insulation material 110.

[0063] Beam 105 may include an air barrier 201a located at its end 111. When the first door is closed, the air barrier 201a is located between the end 111 of beam 105 and the inner wall 103.

[0064] When in use, the air barrier 201a can reduce the flow of cold air in the storage compartment 102 from between the end 111 of the beam 105 and the inner wall 103 opposite to the end 111 toward the doors 107 and 108 of the refrigerator 100, thereby reducing the heat exchange between the cold air and the outside at this point, which also helps to reduce the probability of condensation.

[0065] Figure 3 The image shown is a schematic cross-sectional view of an air barrier according to an embodiment of the present invention. Figure 2-3As shown, the air barrier 201a includes an air barrier portion 206a, which may include a cavity 202a. When the first door 107 is closed, the cavity 202a is located between the end 111 of the beam 105 and the inner wall 103. This helps to enhance the thermal insulation performance of the air barrier 201a and further reduce heat exchange between the storage chamber 102 and the outside.

[0066] The air barrier 206a includes a cavity wall 203a forming a cavity. In one embodiment of the invention, the cavity wall 203a can be flexible. This is advantageous because, in the event that the door sinks below the design value, the flexible cavity wall 203a can deform under a small force, thereby reducing the probability of the air barrier 206a interfering with the housing and being damaged. Preferably, the cavity wall 203a is made of an elastic material.

[0067] When the first door 107 is closed, there can be a gap n between the air barrier 201a and the inner wall 103. Therefore, the air barrier 201a and the housing 101 will not interfere with each other, and the air barrier 201a can have a larger design space to improve the thermal insulation performance of the air barrier 201.

[0068] The end face 205a of the air blocking part 206a can be a plane.

[0069] Cavity 202a is at least partially located outside the receiving space 109. Figure 2 In the embodiment shown, the cavity 202a is completely outside the accommodating space 109.

[0070] The cavity 202a and the accommodating space 109 can be independent and not connected. This way, they will not affect each other.

[0071] Air barrier 201a can be at least partially adhered to the end wall 111 of beam 105. The wall thickness at the adhesion point can be greater than the wall thickness at other locations. Of course, the method of fixing air barrier 202a to beam 105 is not limited to adhesion.

[0072] Figure 4 The image shown is a structural cross-sectional view of an air barrier according to another embodiment of the present invention. Figure 4 As shown, the air blocking member 201b includes an air blocking part 206b and a fixing part 207b. The fixing part 207b is fixedly connected to the end 111 of the beam 105.

[0073] The air barrier 206b includes a cavity 202b. The cavity 202b is formed by a cavity wall 203b extending from one side of the fixing part 207b. Figure 4 In the embodiment shown, the cavity 202b has a bowl-shaped cross-section, and the fixing part 207b has a plate-shaped cross-section.

[0074] When the first door 107 is closed, the ratio of the width of the cavity 202b of the air barrier 201b along the depth direction D of the storage compartment 102 to the thickness of the beam along the depth direction D of the storage compartment 102 is greater than 1:2. This significantly improves the heat insulation performance of the air barrier 201b and also helps to reduce the possibility of condensation in the refrigerator 100.

[0075] The fixing part 207b includes the insertion part 210b. Figure 4 In the embodiment shown, the insertion portion 210b may protrude relative to the air blocking portion 206b toward the front wall 312 and / or rear wall 311 of the beam.

[0076] Of course, the structure of the connector 206b is not limited to Figure 4 As shown in the embodiment, it can also be formed by protruding from the side of the fixing part 207b away from the air blocking part 206b.

[0077] The insertion portion 210b may be provided with a surface 211b inclined towards the air barrier portion. The inclined surface 211b facilitates the quick installation of the air barrier 201b, and is limited by the insertion structure (see attached diagram). Figure 7 This allows the air-blocking component 201b to be secured to the end 111 of the beam 105 in a more reliable manner.

[0078] Figure 5 This is a schematic partial perspective view of a beam used in a refrigerator according to another embodiment of the present invention, as shown below. Figure 5-7 As shown, an air blocking member 201c is provided at the end of the beam 105. The air blocking member 201c includes an air blocking part 206c and a rigid fixing part 207c.

[0079] The air barrier 201 may have an air barrier portion 206c, which may include multiple cavities 202c. When the first door 107 is closed, the multiple cavities 202c may be distributed back-to-back along the depth direction D of the storage chamber 102. The multiple cavities 202c distributed along the depth direction D of the storage chamber 102 reduce the heat exchange rate between the cold air inside the storage chamber 102 and the outside, thus improving the thermal insulation performance of the air barrier portion 206c.

[0080] When the first door 107 is closed, the ratio of the sum of the widths of the cavity 202c of the air barrier 201c along the depth direction D of the storage compartment 102 to the thickness of the beam 105 along the depth direction D of the storage compartment 102 can be greater than 1:2. This is beneficial for significantly improving the heat insulation performance of the air barrier 201 and also helps to reduce the possibility of condensation in the refrigerator 100.

[0081] The air barrier 206c includes a plurality of partitions 204c that separate adjacent cavities 202c. At least one end of each partition 204c is connected to the cavity wall 203c constituting the air barrier 206c. On the one hand, the partitions 204c divide the air barrier 206c into a plurality of cavities 202c that are not interconnected in the depth direction D of the storage chamber 102; on the other hand, the partitions 204c help maintain the shape stability of the cavities 202c.

[0082] Multiple partitions 204c can extend along the width direction of beam 105 and have a constant cross-section. This is beneficial for improving the consistency of the performance of the air barrier in the width direction of the beam, and it also provides a possibility for the mass production of the partitions 204c of the air barrier 201c integrally molded with its cavity wall 203c.

[0083] When the first door 107 is closed, the multiple partitions 204c can be distributed back-to-back and parallel along the depth direction D of the storage chamber 102. The multiple partitions 204 form multiple cavities 202c that are distributed back-to-back and parallel along the depth direction D of the storage chamber 102, which helps to reduce the heat exchange rate and thus improve the heat insulation effect of the air barrier 206c.

[0084] The thickness of the partition 204c can be less than the thickness of the cavity wall 203c that forms the outer surface of the air barrier 206c. Preferably, the ratio is no more than two-thirds. This thickness design is beneficial for improving the flatness of the cavity wall 203c of the air barrier 201c and is relatively beneficial for the deformability of the air barrier 206c.

[0085] The fixing part 207c can be configured as part of the cavity wall of the cavity 202c. The fact that the fixing part 207c is part of the cavity wall 203c of the cavity 202c helps to reduce the overall thickness of the air blocking member 201c.

[0086] exist Figure 7 In the illustrated embodiment, the fixing part 207c is plate-shaped, and the air blocking part 206c is flat. The plate-shaped structure of the fixing part 207c and the flat structure of the air blocking part 206c help to reduce the overall thickness of the air blocking member 201c while still ensuring the thermal insulation performance of the air blocking member 201c in the depth direction D of the storage chamber 102.

[0087] The air barrier 206c may include a neck 208c extending from one side of the rigid fixing portion 207c, and a main body 209c extending from the neck 208c toward the front wall 312 and rear wall 311 of the beam 105 to form a cavity 202c. This is beneficial for maximizing the height of the cavity 202c of the air barrier 206c, thereby improving the heat insulation effect of the air barrier 206c.

[0088] The beam 105 may include a first housing portion 301 and a second housing portion 303, which are connected to form a receiving space 109 for accommodating the thermal insulation material 110.

[0089] A groove 302 located outside the receiving space 109 may be provided on the end wall of the end 111 of the beam 105. The groove 302 opens toward the inner wall 103, and the fixing part 207c can be at least partially received in the groove 302. Figure 7 In one embodiment, the fixing part 207c is entirely housed within the groove 302.

[0090] The first housing portion 303 may include a first receiving portion 305, and the second housing portion 301 includes a second receiving portion 304. When the first housing portion 303 and the second housing portion 301 are connected, the first receiving portion 305 and the second receiving portion 304 overlap to form a groove 302, and the overlapping portion has a distance a along the length direction of the beam. The insertion portion 210c of the fixing portion 207c is clamped in the distance a. Such a groove limiting structure simplifies the installation process of the air barrier.

[0091] Figure 7 In the illustrated embodiment, the first receiving part 305 can serve as a component of the accommodating space 109. Thus, the first receiving part 305 can support the heat insulation material 110 while ensuring that the accommodating space 109 and the cavity 202c of the air barrier 201c are independent and not interconnected, thereby preventing them from interfering with each other.

[0092] The groove 302 may have a T-shaped cross-section, with the neck 208c passing through the opening of the groove 302. By adapting the shape of the neck 208c to the opening of the groove 302, it is beneficial to reduce the overall thickness of the air barrier 201c.

[0093] The end of the air blocking part 206c near the front wall 312 of the beam should preferably not extend beyond the front wall 312 to prevent interference between the beam 105 and the side of the door when it rotates.

[0094] exist Figure 6 In the embodiment shown, when the first door 107 is closed, the cavity 202c of the air barrier 206c is not open along the depth direction D of the storage chamber 102, which helps to reduce the heat exchange rate along the depth direction D of the storage chamber 102.

[0095] Meanwhile, the cavity 202c of the air barrier 206c is open along the width direction of the beam 105. This makes the molding process of the air barrier 201c relatively simple and the cost relatively low.

[0096] However, in other embodiments of the present invention, the cavity 202a of the air barrier 201a can be closed, which is advantageous for improving the thermal insulation performance of the air barrier 201a. Furthermore, the closed cavity 202a can be filled with an inert gas, which further improves the thermal insulation performance of the air barrier 202a.

[0097] exist Figure 7 In the illustrated embodiment, when the first door 107 is closed, a gap n is provided between the end face 205c of the air barrier 201c facing the inner wall 103 of the storage compartment 102 and the inner wall 103 of the storage compartment 102. This helps to prevent or reduce interference between the beam and the refrigerator body during use.

[0098] Preferably, the gap n is not less than 1mm. At the same time, it is beneficial to ensure the heat insulation effect of the air barrier. The gap n is preferably not greater than 5mm.

[0099] A front panel 306 is provided on the front wall 312 of beam 105. A heating element 307 may be provided on the inside of the front panel 306 to prevent condensation. The air barrier 201 and the front panel 306 are fixed to beam 105 in a non-contact manner, which helps to prevent heat exchange between the air barrier 202c and the front panel 306 or the heating element 307 in the front panel 306.

[0100] Air blocking components 201a, 201b, and 201c can be mass-produced using a one-piece molding process.

[0101] The fixing parts 207b and 207c of the air-blocking components 201b and 201c can be made of different materials than the air-blocking parts 206b and 206c. For example, the fixing parts 207b and 207c can be made of ABS plastic, while the air-blocking parts 207b and 207c can be made of rubber. In this case, mass production can be carried out through a soft and hard co-extrusion integral molding process.

[0102] according to Figure 7 The installation steps of the air barrier 201 in the illustrated embodiment may include:

[0103] 1) Connect the air blocking member 201c to the first housing portion 303; and

[0104] 2) Connect the first housing part 303 and the second housing part 301.

[0105] In step 1), connecting the air blocker 201c to the first housing portion 303 may include attaching the air blocker 201c to the first housing portion 303.

[0106] In step 1), connecting the air blocker 201c to the first housing portion 303 may include inserting a portion of the fixing portion 207c (e.g., the insertion portion 210c) of the air blocker 201c into the second receiving portion 305 located in the first housing portion.

[0107] In step 2), connecting the first housing portion 301 and the second housing portion 301 may include another part of the fixing portion 207c that covers a portion of the first housing portion 301 with respect to the air barrier 207b.

[0108] In one embodiment, the air barrier 201c is attached to the first housing portion 303 to form a pre-assembled component before participating in the beam assembly. In other words, the step of attaching the air barrier 201c to the first housing portion 303 precedes the step of fitting the insulation material to the first housing portion 303.

[0109] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
