Description

Technical Field

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

[0002] At present, the light box, sensor box, display panel box, etc. inside the refrigerator are fixed on the refrigerator liner through a pre-embedded box. The pre-embedded box is set in the foaming layer between the liner and the refrigerator shell, and the light frame, sensor bracket, etc. are set inside the liner to assemble with the pre-embedded box.

[0003] The bracket and the embedded box in the embedded box can be fixed by a buckle structure. At present, the buckles of the bracket and the embedded box are mostly designed as traditional trapezoidal buckles. In order to adapt to the change of the wall thickness of the inner tank, the matching gap between the buckles is left larger. When the wall thickness of the inner tank becomes thinner, the gap between the bracket and the surface of the inner tank will become larger, affecting the appearance.

[0004] 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.

[0032] Compared with the prior art, the advantages and positive effects of the utility model are:

[0033] In the above embodiment, the design of the clamping structure in the refrigeration device can adapt to the situation where the distance between the embedded box and the inner surface of the inner tank is uncertain due to the change of the wall thickness of the inner tank, ensuring that the installation piece can still be assembled smoothly and maintain a certain pre-tightening force. At the same time, the gap between the installation piece and the inner surface of the inner tank will also be reduced. Even if the embedded box is tilted due to the uneven local wall thickness of the inner tank, it will not affect the assembly effect. The gap between the installation piece and the inner surface of the inner tank is still kept very small, and the overall appearance is not affected.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0058] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. 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.

[0059] The refrigeration device in the present application generally comprises a box body, a door body and a refrigeration system, wherein at least a refrigeration compartment is formed in the box body, and the refrigeration compartment is opened and closed through the door body to meet the requirements of storing and retrieving articles.

[0060] The refrigeration system uses a compressor, condenser, expansion valve and evaporator to perform the refrigeration cycle of the refrigeration equipment. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation to achieve cooling of the items in the box.

[0061] The low-temperature and low-pressure refrigerant enters the compressor, which compresses it into high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0062] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the low-temperature and low-pressure refrigerant gas to the compressor. The evaporator can cool the items in the box by utilizing the latent heat of evaporation of the refrigerant.

[0063] like Figure 1-Figure 10 As shown, some embodiments of the present application provide a refrigeration device, which includes a box body and a door body.

[0064] The box body includes an outer shell 100 and an inner liner 200 disposed in the outer shell 100 . A foaming cavity is defined between the outer shell 100 and the inner liner 200 for the foaming material to foam to form a heat-insulating layer.

[0065] Among them, Figure 2 As shown, a mounting through hole 210 is provided on the inner liner 200 .

[0066] like Figure 3 As shown, an embedded box 300 is provided between the inner liner 200 and the outer shell 100 . The embedded box 300 is located in the foaming cavity and abuts against the outer surface of the inner liner 200 .

[0067] The embedded box 300 has an open opening opposite to the installation through hole 210 .

[0068] like Figure 4 As shown, a mounting member 400 is disposed inside the inner container 200 . The mounting member 400 is disposed in the embedded box 300 through an open opening, and the mounting member 400 abuts against the inner surface of the inner container 200 .

[0069] The mounting member 400 can be used to install and fix corresponding functional components, such as a display panel, a light panel, a sensor, etc. (not shown in the figure).

[0070] The mounting member 400, the embedded box 300 and the functional components can be assembled to form a lamp box, a display panel box and a sensor box.

[0071] The mounting member 400 is fixedly connected to the embedded box 300 via a snap-fit ​​structure.

[0072] Specifically, see Figure 5 and Figure 6 The snap-fit ​​structure includes a locking member 500 and a snap-fit ​​member 600 .

[0073] The locking member 500 is disposed in the embedded box 300, and the buckle member 600 is disposed on the mounting member 400 corresponding to the locking member 500. The locking member 500 and the embedded box 300 are an integrally formed structure, and the buckle member 600 and the mounting member 400 are an integrally formed structure.

[0074] The locking member 500 has a locking portion 510 having a circular cross-section.

[0075] like Figure 7 The buckle 600 includes two cantilever arc-shaped clamping parts 620 arranged opposite to each other. An opening 630 smaller than the diameter of the locking part 510 is formed between the ends of the two arc-shaped clamping parts 620, and a clamping space is defined inside the opening 630. The locking part 510 is clamped and fixed in the clamping space.

[0076] When the wall thickness of the inner liner 200 increases, the arc-shaped clamping portion 620 of the fastener 600 is forced to open, and the internal stress of the arc-shaped clamping portion 620 causes the mounting member 400 to press the outer surface of the inner liner 200 inward.

[0077] Generally, the local wall thickness of the inner liner 200 at the installation position of the embedded box 300 is approximately in the range of 1 mm to 2 mm.

[0078] like Figure 8 As shown, the fitting clearance between the snap member 600 on the mounting member 400 and the locking portion 510 on the embedded box 300 is designed according to the thinnest case of the inner liner 200. In this example, the wall thickness of the inner liner 200 is 1 mm, and the fitting clearance between the arc-shaped clamping portion 620 of the snap member 600 and the locking portion 510 is 0.05 mm.

[0079] like Fig. 9 As shown, when the local wall thickness of the inner liner 200 is the thickest, such as 2 mm, the snap-fit ​​piece 600 on the mounting piece 400 is deformed and cooperates with the locking portion 510 on the embedded box 300. The snap-fit ​​piece 600 is subjected to pressure from the locking portion 510, and this force causes the snap-fit ​​piece 600 to open. The internal stress of the arc-shaped clamping portion 620 of the snap-fit ​​piece 600 causes the mounting piece 400 to press the outer surface of the inner liner 200 inward, and this pre-tightening force can reduce the gap between the mounting piece 400 and the outer surface of the inner liner 200.

[0080] like Fig.10 As shown, when the local wall thickness of the inner liner 200 is uneven, such as 1 mm on one side and 2 mm on the other side, the embedded box 300 will tilt, but it will not affect the cooperation between the fastener 600 and the locking portion 510. The internal stress of the fastener 600 still reduces the gap between the mounting member 400 and the outer surface of the inner liner 200.

[0081] Through this snap-fit ​​structure design, setting locking parts 510 of different diameters can adapt to inner liner 200 with different wall thickness variations. In theory, the larger the range of variation of the wall thickness of the inner liner 200, the larger the diameter of the locking part 510 needs to be set.

[0082] In the above-mentioned refrigeration equipment, this clamping structure design can adapt to the situation where the distance between the embedded box and the inner surface of the inner tank is uncertain due to the change of the wall thickness of the inner tank, ensuring that the installation parts can still be assembled smoothly and maintain a certain pre-tightening force. At the same time, the gap between the installation parts and the inner surface of the inner tank will also be reduced. Even if the embedded box is tilted due to the uneven wall thickness of the inner tank, it will not affect the assembly effect. The gap between the installation parts and the inner surface of the inner tank remains very small and does not affect the overall appearance.

[0083] In some other embodiments of the present application, the locking member 500 may be disposed on the mounting member 400 , and the snap member 600 is disposed in the embedded box 300 corresponding to the locking member 500 .

[0084] In other embodiments of the present application, the locking member 500 and the embedded box 300 may be separate structures, and the two are fixed together by bonding, clamping or other means. The fastener 600 and the mounting member 400 may be separate structures, and the two are fixed together by bonding, clamping or other means.

[0085] In some embodiments of this application, see Figure 7 The latch 600 further includes two cantilever portions 610 disposed opposite to each other.

[0086] One end of the cantilever portion 610 is connected to the mounting member 400 , and the other end is connected to the arc-shaped clamping portion 620 .

[0087] The two cantilever parts 610 are arranged in parallel, that is, the cantilever parts 610 are in a straight plate shape, which can make the buckle 600 have better elasticity.

[0088] The buckle 600 is an integrally formed structure. The cantilever portion 610 and the arc-shaped clamping portion 620 are smoothly connected, that is, the cantilever portion 610 and the arc-shaped clamping portion 620 are tangent to each other.

[0089] In order to improve the structural strength of the fastener 600, the fastener 600 is a plate-like structure with a certain width.

[0090] In other embodiments of the present application, the cantilever portion 610 may also be arc-shaped, and integrally form a buckle 600 with an arc-shaped structure with the arc-shaped clamping portion 620. The clamping space inside the buckle 600 is adapted to the locking portion 510, and the inner wall of the clamping space is completely in contact with the locking portion 510.

[0091] In order to facilitate the locking part 510 to be inserted into the clamping space, the end surface of the opening 630 of the arc-shaped clamping part 620 is set as an inclined surface 621, and the opening 630 ends of the two arc-shaped clamping parts 620 are relatively arranged to form an opening 630 whose width decreases from the outside to the inside. The inclined surface 621 plays a guiding role when the locking part 510 is inserted into the buckle 600, making it easier to insert into the buckle 600.

[0092] See also Figure 5 The locking portion 510 is a circular boss protruding from the inner wall of the embedded box 300. The circular boss and the embedded box 300 are an integrally formed structure.

[0093] Two circular bosses are arranged opposite to each other in the embedded box 300 , and the embedded box 300 and the mounting member 400 are fixed by two snap fasteners 600 and two locking members 500 .

[0094] In other embodiments of the present application, the locking member 500 may be a stepped circular boss structure, and the boss connected to the inner wall of the embedded box 300 has a larger diameter to improve the structural strength of the locking member 500.

[0095] As shown in the figure, the mounting member 400 has a mounting cavity 420 facing the interior of the inner container 200. Functional components such as a light module and a sensor can be installed in the mounting cavity 420. A cover plate can be provided on the mounting member 400 to cover the mounting cavity 420.

[0096] The mounting member 400 extends outward along the edge of the mounting cavity 420 to form a convex edge 410 ; the mounting member 400 is embedded in the embedded box 300 through the open opening, and abuts against the inner surface of the liner 200 through the convex edge 410 .

[0097] The shape of the flange portion 410 can be adapted to the shape of the mounting through hole 210 on the inner liner 200 . The flange portion 410 is slightly larger than the mounting through hole 210 as a whole so as to be able to abut against the inner surface of the inner liner 200 .

[0098] The buckle 600 is located at the bottom of the mounting member 400 and on both sides of the mounting cavity 420. The opening 630 end of the buckle 600 does not protrude from the bottom surface of the mounting member 400, and the buckle 600 may not protrude from the bottom of the mounting member 400, so that the buckle 600 can avoid occupying too much volume in the height direction.

[0099] Specifically, the bottom surface of the mounting member 400 has a step groove 430 , the latch 600 is disposed in the step groove 430 , the latch 600 is connected to the top surface of the step groove 430 , and the height of the latch 600 is not higher than the height of the step groove 430 .

[0100] Some embodiments of the present application further provide a refrigeration device, which includes a box body and a door body.

[0101] The box body includes an outer shell 100 and an inner liner 200 disposed in the outer shell 100 . A foaming cavity is defined between the outer shell 100 and the inner liner 200 for the foaming material to foam to form a heat-insulating layer.

[0102] The inner liner 200 is provided with a mounting through hole 210 .

[0103] An embedded box 300 is disposed between the inner liner 200 and the outer shell 100 . The embedded box 300 is located in the foaming cavity and abuts against the outer surface of the inner liner 200 .

[0104] The embedded box 300 has an open opening opposite to the installation through hole 210 .

[0105] A mounting member 400 is disposed inside the inner container 200 . The mounting member 400 is disposed in the embedded box 300 through an open opening, and the mounting member 400 abuts against the inner surface of the inner container 200 .

[0106] The mounting member 400 can be used to install and fix corresponding functional components, such as a display panel, a light panel, a sensor, etc.

[0107] The mounting member 400 is fixedly connected to the embedded box 300 via a snap-fit ​​structure.

[0108] Specifically, the snap-fit ​​structure includes a locking member 500 and a snap member 600 .

[0109] The locking member 500 is disposed in the embedded box 300, and the buckle member 600 is disposed on the mounting member 400 corresponding to the locking member 500. The locking member 500 and the embedded box 300 are an integrally formed structure, and the buckle member 600 and the mounting member 400 are an integrally formed structure.

[0110] The locking member 500 has a locking portion 510 having a circular cross-section.

[0111] The buckle 600 includes two cantilever arc-shaped clamping parts 620 arranged opposite to each other. An opening 630 smaller than the diameter of the locking part 510 is formed between the ends of the two arc-shaped clamping parts 620, and a clamping space is defined inside the opening 630.

[0112] As the thickness of the door liner changes, the latch 600 can keep all or most of the locking portion 510 clamped and fixed in the clamping space.

[0113] Generally, the local wall thickness of the inner liner 200 at the installation position of the embedded box 300 is approximately in the range of 1 mm to 2 mm.

[0114] like Figure 8 As shown, the fitting clearance between the snap member 600 on the mounting member 400 and the locking portion 510 on the embedded box 300 is designed according to the thinnest case of the inner liner 200. In this example, the wall thickness of the inner liner 200 is 1 mm, and the locking portion 510 is completely clamped and fixed in the clamping space of the snap member 600. The fitting clearance between the arc-shaped clamping portion 620 of the snap member 600 and the locking portion 510 is 0.05 mm.

[0115] like Fig. 9 As shown, when the local wall thickness of the liner 200 is the thickest, such as 2 mm, the snap member 600 on the mounting member 400 is deformed and cooperates with the locking portion 510 on the embedded box 300. Most of the locking portion 510 is clamped and fixed in the clamping space of the snap member 600. The snap member 600 is subjected to the pressure of the locking portion 510. This force causes the snap member 600 to open. The internal stress of the arc-shaped clamping portion 620 of the snap member 600 causes the mounting member 400 to press the outer surface of the liner 200 inward. This pre-tightening force can reduce the gap between the mounting member 400 and the outer surface of the liner 200.

[0116] like Fig.10As shown, when the local wall thickness of the inner liner 200 is uneven, such as 1 mm on one side and 2 mm on the other side, the embedded box 300 will tilt, but it will not affect the cooperation between the fastener 600 and the locking portion 510. Most of the locking portion 510 is still clamped and fixed in the clamping space of the fastener 600. The internal stress of the fastener 600 still reduces the gap between the mounting member 400 and the outer surface of the inner liner 200.

[0117] Through this snap-fit ​​structure design, setting locking parts 510 of different diameters can adapt to inner liner 200 with different wall thickness variations. In theory, the larger the range of variation of the wall thickness of the inner liner 200, the larger the diameter of the locking part 510 needs to be set.

[0118] In the above-mentioned refrigeration equipment, this clamping structure design can adapt to the situation where the distance between the embedded box and the inner surface of the inner tank is uncertain due to the change of the wall thickness of the inner tank, ensuring that the installation parts can still be assembled smoothly and maintain a certain pre-tightening force. At the same time, the gap between the installation parts and the inner surface of the inner tank will also be reduced. Even if the embedded box is tilted due to the uneven wall thickness of the inner tank, it will not affect the assembly effect. The gap between the installation parts and the inner surface of the inner tank remains very small and does not affect the overall appearance.
