Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration, and in particular, to a refrigeration device. Background Art

[0002] Most traditional refrigerator drawer doors rely on the magnetic attraction force of the door seal and the self-locking force of the guide rail to achieve the tight fit between the door body and the box body. However, for the drawer door inside the box without a magnetic strip design, only relying on the self-locking force of the guide rail cannot achieve an ideal sealing effect.

[0003] In addition, after the refrigerator door body is foam-molded, the inner lining surface often becomes uneven due to factors such as shrinkage and bulging. When the fixed support seat is installed on the foam-molded door body and then assembled onto the box body guide rail, due to the insufficient fixing accuracy of the guide rail, the problem of door body skew is very likely to occur, and the door body may deviate in multiple directions such as front-back and up-down. Summary of the Invention

[0004] In order to at least overcome the above deficiencies in the prior art, the purpose of the present invention is to provide a refrigeration device, including a box body with an opening, a door body, and a connection component: The door body is slidably connected to the box body through the connection component; the door body is used to open or close the opening; The connection component includes a connection support and a fixing plate. The fixing plate and the connection support are sequentially connected to the side of the door body close to the box body through a connecting piece; a protrusion is provided at a position close to the center of the fixing plate in a direction away from the door body.

The protrusion and the groove are fitted, and the connection support can rotate relative to the protrusion; In the direction perpendicular to the side of the door body close to the box body, there is a gap with adjustable distance between the fixing plate and the connection support.

The adjusting bolt abuts against the door body through the third through holes; the adjusting bolt is used to adjust the distance between the third through holes and the door body in the direction perpendicular to the side of the door body close to the box body.

[0006] In a possible implementation, the protrusion is semi-cylindrical. In the direction perpendicular to the bottom wall of the box body, the protrusion divides the fixing plate into a first part and a second part. The gap between the first part and the connecting support is a first sub-gap, and the gap between the second part and the connecting support is a second sub-gap. In the direction perpendicular to the side of the door body close to the box body, the widths of the first sub-gap and the second sub-gap are a first width and a second width respectively; The connection assembly includes at least a first connection state and a second connection state; in the first connection state, the first width is greater than the second width; in the second connection state, the first width is equal to the second width.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] It should be noted that, without conflict, different features in the embodiments of the present invention can be combined with each other.

[0025] After investigation by the inventor, it is found that most traditional refrigerator drawer doors rely on the magnetic attraction of the door seal magnet and the self-locking force of the guide rail to achieve the tight fit between the door body and the box body. However, for the drawer door inside the box without a magnetic strip design, only relying on the self-locking force of the guide rail cannot achieve an ideal sealing effect.

[0026] In addition, after the refrigerator door body is foam-molded, the inner liner surface often becomes uneven due to factors such as shrinkage and bulging. When the fixed support seat is installed on the foam-molded door body and then assembled onto the cabinet guide rail, due to insufficient fixing accuracy of the guide rail, the problem of door body skew is very likely to occur, and the door body may deviate in multiple directions such as front-back and up-down.

[0027] In view of this, the present invention provides a refrigeration device 10. Please refer to Figure 1 and Figure 2 , which includes a cabinet 100 with an opening, a door body 200, and a connection assembly 300.

[0028] In the refrigeration device 10, the cabinet 100 includes a housing and an inner liner, etc. The housing is located on the outermost layer of the refrigeration device 10 and is used to wrap and support the entire refrigeration device 10; the interior of the housing includes an inner liner, that is, a plastic cavity for storing food, etc., forming storage spaces such as a refrigerating chamber and a freezing chamber; a heat insulation layer is also formed by foaming between the housing and the inner liner and inside the door body 200 to improve the refrigeration effect of the refrigeration device 10.

[0029] The door body 200 is slidably connected to the cabinet 100 through the connection assembly 300; the door body 200 is used to open or close the opening.

[0030] In this embodiment, the door body 200 may include a drawer door, and the drawer door may be connected to the cabinet 100 through connection assemblies 300 such as guide rails, so as to realize the sliding connection between the door body 200 and the cabinet 100.

[0031] Please refer to Figure 3 , the connection assembly 300 includes a connection support 320 and a fixing plate 310. The fixing plate 310 and the connection support 320 are sequentially connected to the side of the door body 200 close to the cabinet 100 through a connecting member 400; a protrusion 311 is provided at a position close to the center of the fixing plate 310 in a direction away from the door body 200. In the direction perpendicular to the bottom wall of the cabinet 100, the cross-sectional shape of the end of the protrusion 311 away from the door body 200 is a sector with the center of the circle close to the door body 200; a groove 321 matching the protrusion 311 is provided at a position close to the center of the connection support 320. The protrusion 311 and the groove 321 are fitted, and the connection support 320 can rotate relative to the protrusion 311.

[0032] In this embodiment, a fixing plate 310 with a protrusion 311 in a direction away from the door body 200 can be provided between the connection support 320 and the door body 200. The cross-sectional shape of the end of the protrusion 311 away from the door body 200 is arc-shaped, and the connection support 320 has a groove 321 matching the protrusion 311. The connection support 320 can rotate relative to the protrusion 311.

[0033] Thus, in a direction perpendicular to the surface of the door body 200 close to the cabinet body 100, there is a gap 330 with adjustable distance between the fixed plate 310 and the connecting support 320. For example, in a direction perpendicular to the bottom wall of the cabinet body 100, the protrusion 311 can at least divide the fixed plate 310 into an upper half and a lower half, corresponding to two sub-gaps formed between them and the connecting support 320 respectively. Since the connecting support 320 rotates relative to the protrusion 311, in a direction perpendicular to the surface of the door body 200 close to the cabinet body 100, the widths of the two sub-gaps can be adjusted. If the connecting support 320 rotates upward relative to the protrusion 311, the width of the upper half sub-gap decreases, and the width of the lower half sub-gap increases accordingly.

[0034] After foaming, the door body 200 may have an uneven surface on the side close to the inner tank due to shrinkage, bulging, etc. After connecting the foamed door body 200 to the cabinet body 100 through the connecting component 300, problems such as the skew of the door body 200 may occur. Therefore, in the present invention, a fixed plate 310 is provided between the connecting support 320 and the door body 200. When manufacturing the refrigeration device 10 of the present invention, the following steps can be taken.

[0035] First, fix the fixed plate 310 on the side of the door body 200 close to the inner tank before foaming the door body 200; then, after foaming the door body 200, first abut the fixed plate 310 against the door body 200 through the connecting piece 400 to position the fixed plate 310, and the distance at which the connecting piece 400 abuts the fixed plate 310 against the door body 200 is adjustable; finally, fix the connecting support 320 and the fixed plate 310 on the door body 200 through the connecting piece 400. Among them, during the first installation of the refrigeration device 10, the protrusion 311 on the fixed plate 310 is in full contact with the groove 321 of the connecting support 320, and there is an adjustable floating gap 330 between the fixed plate 310 and the connecting support 320. Thus, when the contact surface between the side of the door body 200 close to the inner tank and the connecting support 320 is uneven due to foaming of the door body 200, since there is a connecting piece 400 that abuts the fixed plate 310 against the door body 200 to adjust the width of the gap 330 between them, the flat installation of the connecting support 320 can still be ensured.

[0036] In addition, when it is found that the door body 200 sinks after the door body 200 is installed or loaded, resulting in inconsistent distances between various parts of the door body 200 and the box body 100, the gap 330 between the fixing plate 310 and the connecting support 320 can be adjusted through the connecting member 400, so that the distances between various parts of the door body 200 and the box body 100 are consistent. For example, when it is found that the gap 330 between the upper part of the door body 200 and the box body 100 is greater than the gap 330 between the lower part of the door body 200 and the box body 100, the connecting member 400 can be adjusted to make the connecting support 320 rotate clockwise relative to the convex 311, so that the gaps 330 between the upper and lower parts of the door body 200 and the box body 100 are kept consistent.

[0037] In a possible implementation manner, please refer to Figure 3 , the connecting member 400 includes a fixing bolt 410 and an adjusting bolt 420; the fixing plate 310 includes a plurality of first through holes 312, the connecting support 320 includes a plurality of second through holes 322 corresponding to the first through holes 312, and the fixing bolt 410 is used to fix the connecting component 300 on the door body 200 through the first through holes 312 and the second through holes 322.

[0038] In this embodiment, the fixing bolt 410 is used to connect the connecting support 320 and the fixing plate 310 to the door body 200 in sequence. When installing the refrigeration device 10 or adjusting the gap 330 between the fixing plate 310 and the connecting support 320, the fixing bolt 410 can be loosened, disassembled and tightened by tools such as a wrench to cooperate with the adjusting function of the adjusting bolt 420.

[0039] The fixing plate 310 includes a plurality of third through holes 313, and the adjusting bolt 420 abuts against the door body 200 through the third through holes 313; the adjusting bolt 420 is used to adjust the distance between the third through holes 313 and the door body 200 in a direction perpendicular to the surface of the door body 200 close to the box body 100.

[0040] In this embodiment, the adjusting bolt 420 can adjust the distance between the third through holes 313 and the door body 200 through tools such as a wrench, and further adjust the width of the gap 330 between the fixing plate 310 and the connecting support 320, so that the gaps 330 between the upper and lower parts of the door body 200 and the box body 100 are kept consistent.

[0041] In addition, a plurality of accommodating grooves corresponding to the adjusting bolts 420 can be provided on the connecting support 320. In this way, the connecting component 300 of the refrigeration device 10 is more beautiful after installation or adjustment.

[0042] Optionally, the accommodation groove on the connection support 320 is a detachable accommodation groove. In this way, when adjusting the width of the gap 330 between the fixed plate 310 and the connection support 320 using the adjusting bolt 420, it is only necessary to loosen the fixing bolt 410 with a tool.

[0043] In a possible implementation manner, please refer to Figure 3 and Figure 4 , the protrusion 311 is in the shape of a semi-cylindrical body. In the direction perpendicular to the bottom wall of the box body 100, the protrusion 311 divides the fixed plate 310 into a first part 3101 and a second part 3102. The gap 330 between the first part 3101 and the connection support 320 is a first sub-gap 331, and the gap 330 between the second part 3102 and the connection support 320 is a second sub-gap 332. In the direction perpendicular to the surface of the door body 200 close to the box body 100, the widths of the first sub-gap 331 and the second sub-gap 332 are a first width D1 and a second width D2 respectively.

[0044] The connection assembly 300 has at least a first connection state and a second connection state; in the first connection state, the first width D1 is greater than the second width D2; in the second connection state, the first width D1 is equal to the second width D2.

[0045] In a possible implementation manner, the first part 3101 has at least one first through hole 312 and one third through hole 313; the second part 3102 has at least one first through hole 312 and one third through hole 313.

[0046] In this embodiment, the connection support 320 is supported by the semi-cylindrical protrusion 311 of the fixed plate 310 and the adjusting bolt 420 together, so that it floats on the side of the door body 200 close to the inner container. Even if the door liner foams and bulges, resulting in unevenness, it will not affect the sealing performance between the door body 200 and the box body 100, and the qualified rate of the assembled door body 200 is improved. Specifically, the semi-cylindrical protrusion 311 of the fixed plate 310 can be used to support the connection support 320. The protrusion 311 contacts the groove 321 of the connection support 320. The adjusting bolt 420 of the first part 3101 and the second part 3102 can be used to adjust the gap 330 between the fixed plate 310 and the connection support 320. This type of adjustable floating of the door body 200 is different from the adjustment close to the door body 200, which can avoid the interference of uneven foaming of the door body 200.

[0047] When installing the connection component 300, a plane is first determined through the contact at the two adjusting bolts 420 and the protrusion 311. When installing the door body 200 onto the box body 100, if there is a problem with poor sealing during the installation of the door body 200, the widths of the gaps 330 between the upper and lower parts of the door body 200 and the box body 100 can be measured respectively, and the adjusting bolts 420 at the corresponding positions can be adjusted to ensure that the distances between the upper and lower parts of the door body 200 and the box body 100 are relatively consistent after the installation of the door body 200.

[0048] Specifically, please refer to Figure 4 , the fixing plate 310 includes two first through holes 312 and a third through hole 313 located in the first part 3101 of the protrusion 311; and two first through holes 312 and a third through hole 313 located in the second part 3102 of the protrusion 311. In this way, the adjustment of the upper and lower parts of the door body 200 can be achieved through the adjusting bolts 420 and the fixing plate 310.

[0049] In a possible implementation manner, please refer to Figure 5 , the protrusion 311 is in a hemispherical shape, and any straight line where the diameter of the hemispherical protrusion 311 is located divides the fixing plate 310 into a third part and a fourth part; the gap 330 between the third part and the connecting support 320 is a third sub-gap, and the gap 330 between the fourth part and the connecting support 320 is a fourth sub-gap. In the direction perpendicular to the surface of the door body 200 close to the box body 100, the widths of the third sub-gap and the fourth sub-gap are the third width and the fourth width respectively.

[0050] The connection component 300 has at least a third connection state and a fourth connection state; in the third connection state, the third width is greater than the fourth width; in the fourth connection state, the third width is equal to the fourth width.

[0051] In a possible implementation manner, the fixing plate 310 includes at least three first through holes 312 and three third through holes 313 respectively located on different sides of the protrusion 311.

[0052] In this embodiment, the hemispherical protrusion 311 of the fixing plate 310 and the adjusting bolt 420 jointly support the connecting seat 320, making it suspended on the side of the door body 200 close to the inner liner. Even if the door liner foams and bulges, causing unevenness, it will not affect the sealing performance between the door body 200 and the box body 100, improving the qualified rate of the assembled door body 200. At the same time, when there are problems with the door body 200 of the refrigeration device 10, it can also be adjusted through the fixing plate 310 and the adjusting bolt 420. Specifically, the hemispherical protrusion 311 of the fixing plate 310 can be used to support the connecting seat 320, and the protrusion 311 contacts the groove 321 of the connecting seat 320. With multiple adjusting bolts 420, the gap 330 between the fixing plate 310 and the connecting seat 320 can be adjusted in different directions.

[0053] According to the principle that three points determine a plane, at least three first through holes 312 and three third through holes 313 are respectively arranged on the fixing plate 310 on different sides of the protrusion 311. Correspondingly, the connecting member 400 includes three adjusting bolts 420 and three fixing bolts 410. When installing the connecting component 300, a plane is first determined through the contact of the three adjusting bolts 420 and the protrusion 311. When installing the door body 200 onto the box body 100, if there are problems affecting the installation of the door body 200 due to the positioning accuracy of the guide rail connected to the connecting seat 320, the width of the gap 330 between each angle of the door body 200 and the box body 100 can be measured, and the adjusting bolts 420 at the corresponding positions can be adjusted to ensure that the distances between the door body 200 and the box body 100 in all directions are relatively consistent after installing the door body 200.

[0054] It should be noted that the universal adjustment between the fixing plate 310 and the connecting seat 320 can be realized through the hemispherical protrusion 311 and the adjusting bolt 420 in this embodiment. Therefore, the number of the second through holes 322 can be adjusted according to the use scenario.

[0055] Specifically, please refer to Figure 5 There are four first through holes 312 and four third through holes 313 respectively located on different sides of the protrusion 311 on the fixing plate 310. In this way, the adjustment of the door body 200 in four directions can be realized through the adjusting bolt 420 and the fixing plate 310.

[0056] In a possible implementation manner, the protrusion 311 is detachably connected to the fixing plate 310.

[0057] In this embodiment, the connection mode between the protrusion 311 and the fixing plate 310 can be set as a detachable connection. In this way, when the protrusion 311 is worn due to long-term use, only the protrusion 311 on the fixing plate 310 can be replaced. When using the refrigeration device 10 of the present application, the user can replace the accessories of the protrusion 311 by himself.

[0058] Specifically, the protrusion 311 and the fixing plate 310 can be connected by means of snap connection, buckle connection, etc., and no specific limitation is made here.

[0059] It should be noted that in other possible embodiments, the protrusion 311 and the fixing plate 310 can also be connected by welding or bonding. In this way, the protrusion 311 on the fixing plate 310 can be made more stable. No specific limitation is made here.

[0060] In a possible embodiment, the material of the fixing plate 310 includes plastic.

[0061] Plastic has a relatively small density. When the fixing plate 310 is installed on the refrigeration device 10, there will be no large weight burden, and at the same time, the operation difficulties such as production, handling, and installation of the fixing plate 310 are reduced; compared with other materials, the material cost and processing cost of plastic are lower; the maintenance cost of plastic is low, and it is not easy to deform or corrode in a low-temperature environment. Therefore, in this embodiment, plastic is selected as the material for making the fixing plate 310.

[0062] It should be noted that in other possible embodiments, other materials can also be used for the fixing plate 310, and no specific limitation is made here. For example, the material of the fixing plate 310 can be a sheet metal part. Using a sheet metal part as the material for making the fixing plate 310 can bear a larger load compared with other materials. At the same time, the sheet metal part can integrate structures such as threaded holes and buckles, thus simplifying the production process. At the same time, the sheet metal part can enhance the corrosion resistance and aesthetics through surface treatments such as spraying and electroplating to adapt to the environment inside the refrigeration device 10.

[0063] In a possible embodiment, the material of the protrusion 311 includes a wear-resistant material.

[0064] In this embodiment, the material of the protrusion 311 should be subjected to wear resistance treatment or a wear-resistant material should be selected. In this way, the service life of the fixing plate 310 and the protrusion 311 located thereon can be extended.

[0065] It should be noted that for the fixing plate 310 and the protrusion 311 made of sheet metal parts, the surface of the protrusion 311 needs to be hardened and acid and alkali resistant treated.

[0066] In a possible embodiment, the connection assembly 300 includes a guide rail disposed in the box body 100 and a sliding part connected to the connection support 320.

[0067] The sliding part is slidably connected to the guide rail, and the sliding part is used to drive the door body 200 to slide along the guide rail in a direction perpendicular to the surface of the door body 200 close to the box body 100.
