Description

TECHNICAL FIELD

[0001] The present application relates to the field of refrigeration technology, and in particular to a cabinet for a refrigeration device and a refrigeration device. BACKGROUND

[0002] Due to the demand for larger refrigeration compartments, some refrigeration devices omit the use of a middle beam in the refrigeration compartment. However, without a middle beam, the internal freezing temperature of the refrigeration device reaches below -18℃, while the temperature outside the refrigeration device is basically 20℃, and even reaches above 35℃ in summer. The inner liner on the inside of the cabinet is made of plastic sheet material, and the inner liner and the foamed material shrink due to the cold, while the outer steel plate expands due to the heat. The deformation amount and direction of the heat expansion and cold shrinkage of the two are different, which causes the side of the cabinet to be concave. Currently, some manufacturers use a solution of adding a reinforcing plate inside the refrigeration device, but adding a reinforcing plate inside the cabinet increases the production cost and affects the optimal design of the inner liner of the refrigeration device.

[0003] Therefore, it is necessary to improve the existing cabinet to solve the above technical problems. SUMMARY

[0024] In order to make the skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the skilled in the art without creative labor should belong to the protection scope of the present application.

[0025] It should be noted that the terms "upper", "lower", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the auxiliary drawing, and are only used to facilitate the description of the present application, and do not indicate or imply that the device must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the scope of protection of the present application. Specifically, in the present application, the user's operation surface is the front, and the direction towards the ground is the lower, and conversely, the direction away from the ground is the upper, and other orientation descriptions are defined based on the "upper" and "lower".

[0026] In various drawings of the present application, some dimensions of structures or parts may be exaggerated relative to other structural parts for the purpose of illustration, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0027] A box for refrigeration equipment, as shown in Figures 1 to 5 includes an inner container (not shown) and a shell 10 located outside the inner container. The present application solves the problem of deformation of the box caused by different deformation amounts and directions of the shell 10 and the inner container when the inner and outer temperatures of the box are greatly different by changing the design of the shell.

[0028] Specifically, as shown in Figure 1As shown, the shell 10 is provided with at least one blocking groove 20 distributed along the height direction of the shell 10; the blocking groove 20 extends along the width direction of the shell 10, and penetrates the shell 10 in the inward and outward direction, which can effectively block the deformation of the shell 10 caused by thermal expansion, so that the deformation difference between the shell 10 and the inner container is smaller, avoiding the problem of inward sagging of the cabinet, thereby improving the service life of the refrigeration equipment and user experience.

[0029] Specifically, during use, the area where the cabinet deformation is the largest is located at the middle position in the height direction, and the blocking groove 20 is arranged at the middle area in the height direction of the shell 20, so that the position of the blocking groove 20 matches the position of the cabinet deformation of the refrigeration equipment, thereby avoiding the deformation of the shell 10 to the greatest extent.

[0030] In some embodiments, the shell 10 can also be provided with two blocking grooves 20, which are uniformly distributed on the shell 10 along the height direction of the shell 10, and the two blocking grooves 20 jointly solve the deformation problem of the shell 10 caused by thermal expansion.

[0031] Further, the shell 10 has a pair of side walls 11, and since the side wall 11 is adjacent to the opening of the cabinet, the side wall is prone to inward sagging, so the blocking groove 20 is located on the side wall 11 of the shell 10.

[0032] As a preferred embodiment of the present application, as shown in Figure 3 , Figure 4 The width of the front end of the blocking groove 20 in the height direction of the shell 10 is greater than the width of the rear end of the blocking groove 20 in the height direction of the shell 10. Since the cabinet is provided with a door body, the support strength of the front end of the cabinet close to the door body is smaller than that of the rear end of the cabinet, and therefore the deformation caused by preheating expansion of the front end of the shell 10 is greater than that of the rear end of the shell 10. The embodiment designs different sizes at the two ends of the blocking groove 20 to solve the problem that the deformation of the front end of the shell 10 is greater than that of the rear end of the shell 10, thereby improving the adaptability of the shell 10.

[0033] Of course, the distance from the front end of the blocking groove 20 to the front end of the shell 10 is smaller than the distance from the rear end of the blocking groove 20 to the rear end of the shell 10, that is, the blocking groove 20 is arranged at a position close to the front end of the side wall, which can also solve the problem that the deformation of the front end of the shell 10 is greater than that of the rear end of the shell 10.

[0034] Generally, the size of the blocking groove 20 in the height direction of the shell 10 is determined by the deformation of the inner container and the deformation of the shell 10. For example, the deformation of the inner container is X, the deformation of the shell 10 is Y, and the total deformation of the shell 10 and the inner container is X+Y because the deformation directions of the shell 10 and the inner container are opposite. Therefore, the width of the blocking groove 20 should be at least X+Y to offset the total deformation of the shell 10 and the inner container.

[0035] Further, the blocking groove 20 comprises a first blocking groove 21 located in the middle region of the side wall to adjust the deformation of the upper and lower parts of the shell 10.

[0036] Preferably, the front and back widths of the first blocking groove in the height direction of the shell 10 are consistent, and the inner diameter of the first blocking groove 21 in the height direction of the shell 10 ranges from 2mm to 9mm to better block the deformation of the shell 10. In this embodiment, the width of the first blocking groove 21 is in the optimal width range obtained by combining the properties of the material and the working temperature, so that the deformation difference between the shell 10 and the inner container is small, effectively solving the problem of deformation of the cabinet of the refrigeration equipment.

[0037] The inner diameter of the first blocking groove 21 in the width direction of the shell 10 is between one-third and two-thirds of the width of the shell 10. The appropriate size of the first blocking groove 21 can block the deformation of the shell 10 in the width direction caused by thermal expansion, and does not affect the overall structural strength of the shell 10.

[0038] As another preferred embodiment of the present application, as shown in Figure 2 The blocking groove 20 further comprises a second blocking groove 22 located above and / or below the first blocking groove 21. The inner diameter of the second blocking groove 22 is smaller than that of the first blocking groove 20, and the second blocking groove 22 is used to assist the first blocking groove 21 to block the deformation of the shell caused by thermal expansion.

[0039] In this embodiment, two second blocking grooves 22 are provided on the shell 10 in the height direction of the shell 10. When the refrigeration equipment is high, the distance from the first blocking groove 21 to the upper end of the shell 10 or the distance from the first blocking groove 21 to the lower end of the shell 10 is large, that is, the upper region or the lower region of the first blocking groove 21 still exists the deformation of the shell 10. This embodiment uses the second blocking groove 22 to further block or adjust the deformation of the upper and lower regions of the first blocking groove 21 caused by thermal expansion.

[0040] Further, the distance between the second blocking groove 22 and the front end of the side wall 11 is less than the distance between the second blocking groove 22 and the rear end of the side wall 11. That is, the second blocking groove 22 is closer to the front end of the side wall 11, so that the deformation of the front end portion of the side wall 11 during thermal expansion is blocked by both the first blocking groove 21 and the second blocking groove 22, and the deformation of the rear end portion of the side wall 11 during thermal expansion is blocked by the first blocking groove 21, thereby solving the problem that the deformation of the front end of the shell 10 near the door body of the refrigeration equipment is greater than the deformation of the rear end of the shell 10.

[0041] When the refrigeration equipment is relatively high, the area of the shell 10 that is prone to deformation due to heat is also relatively large in the height direction of the shell 10. Preferably, one of the second blocking grooves 22 is located at the middle of the first blocking groove 21 to the upper end of the shell 10, and the other second blocking groove 22 is located at the middle of the first blocking groove 21 to the lower end of the shell 10, so that the first blocking groove 21 and the second blocking groove 22 are located in the area of the shell 10 that is prone to deformation, and the second blocking groove 22 assists the first blocking groove 21 in blocking the deformation of the shell 10, thereby solving the problem that the deformation of the shell 10 of a relatively high refrigeration equipment is relatively large.

[0042] Preferably, in the height direction of the shell 10, the inner diameter of the second blocking groove 22 ranges from 1 mm to 3 mm, and in the width direction of the shell 10, the inner diameter of the second blocking groove 22 is not greater than half the width of the shell 10, so as to ensure that the second blocking groove 22 does not affect the overall strength of the shell 10.

[0043] It can be understood that only one second blocking groove 22 is arranged above or below the first blocking groove 21, or multiple second blocking grooves 22 are arranged above and below the first blocking groove 21, which can also achieve the same technical problem and are within the protection scope of the present application.

[0044] In some specific embodiments, the front and rear widths of the first blocking groove 21 and / or the second blocking groove 22 in the height direction of the shell are consistent, or the width of the front end of the adjacent side wall in the height direction of the shell of the first blocking groove 21 and / or the second blocking groove 22 is greater than the width of the rear end, which are within the protection scope of the present embodiment.

[0045] Further, as shown in FIG. 2, the second blocking groove 22 is arranged on the side wall 11 of the shell 10, and the second blocking groove 22 is arranged on the side wall 11 of the shell 10 in a direction perpendicular to the first blocking groove 21. Figure 5As shown, the shell 10 further comprises a cover 40 for covering the blocking groove 20, the cover 40 comprises a base 41 for covering the blocking groove 20, and a clamping structure 42 protruding inwardly from the base 41 to be capable of clamping with the blocking groove 20. By covering the blocking groove 20 with the cover 40, on the one hand, the appearance of the shell 10 is more neat, and the strength at the blocking groove 20 is compensated, on the other hand, the structure inside the shell 10 is protected, and the appearance and safety of the refrigeration equipment are improved.

[0046] Specifically, the clamping structure 42 comprises a pair of connecting portions 421 connected to the base 41, a pair of limiting portions 422 respectively connected to one end of the pair of connecting portions 421 away from the base 41 and protruding outwardly in opposite directions, and a plug-in portion 423 connected to one end of each limiting portion 422 away from the connecting portion 421. In the length or width direction of the blocking groove 20, the maximum size of the pair of limiting portions 422 is greater than the inner diameter size of the blocking groove 20. The clamping groove 424 is formed between the base 41, the connecting portion 421 and the limiting portion 422, and the end of the shell 10 adjacent to the blocking groove 20 is limited in the clamping groove 424, so as to fix the cover 40 on the shell 10.

[0047] It can be understood that the protruding direction of the limiting portion 422 can be along the width direction of the blocking groove 20 or along the length direction of the blocking groove 20, both of which can realize the fixation of the cover 40. In order to better match the clamping structure 42 with the shell 10, the protruding direction of the limiting portion 422 is preferably along the length direction of the blocking groove 20.

[0048] It can be understood that the size and specific shape of the base 41 are matched with the inner diameter size and shape of the first blocking groove 21 and the second blocking groove 22, and the maximum size of the limiting portion 422 is greater than the inner diameter size of the first blocking groove 21 and the second blocking groove 22, so as to better realize the fixation of the cover 40.

[0049] During the process of installing the shell 10 on the outside of the inner container to form a box body, the cover 40 is pre-installed on the shell 10, and then foaming is performed, so that the clamping structure 42 is in the foaming layer, and the cover 40 is further fixed. At the same time, the specific structural form of the clamping structure 42 can withstand the extrusion of the foaming layer inside the shell 10 when the shell 10 deforms, and plays a buffering role for the deformation of the box body as a whole.

[0050] The application also relates to a refrigeration device, wherein the refrigeration device comprises the above-mentioned cabinet and a door body for opening or closing the cabinet.

[0051] In conclusion, the cabinet for the refrigeration device is provided with at least one blocking groove 20 penetrating the outer shell 10 in the inner-outer direction in the height direction of the outer shell 10, the deformation of the outer shell 10 caused by thermal expansion is blocked by the blocking groove 20, so that the deformation difference between the outer shell 10 and the inner container is small, the problem of inward concave of the cabinet is avoided, and the service life and user experience of the refrigeration device are improved
