Description

Technical Field

[0001] The present application relates to the technical field of household appliances, for example, to a damper fixing structure and a refrigerator. Background Art

[0002] At present, most refrigerator dampers are installed by snap-on fixing, which causes the buckle to be squeezed during the foaming process, resulting in stress changes, making it necessary to press the buckle with greater force, or even impossible to press, making it difficult or impossible to remove the damper. In addition, the existing damper fixing buckle does not have a corresponding adjustment amount, and cannot fix the damper well, resulting in the damper still shaking after installation. At the same time, the damper connector used to install the damper will also be squeezed during the foaming process, causing the damper installation space to deform, making it difficult or impossible to disassemble the damper.

[0003] In the related art, there is a damper air supply device, in which the damper assembly is fixed in the installation space inside the connector by a traditional buckle. However, the traditional buckle does not have a corresponding adjustment margin, and after the buckle fixes the damper assembly, there is still a gap between the buckle and the damper assembly, causing the damper assembly to shake.

[0004] Therefore, it can be seen that how to increase the adjustment amount of the buckle, reduce the gap between the buckle and the damper assembly, and fix the damper assembly more firmly has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The disclosed embodiment provides a damper fixing structure and a refrigerator, wherein an elastic limiter assembly that can be elastically retracted and obliquely slidable replaces the fixing buckle used in the prior art, thereby reducing the stress effect under the action of external force, so that when the elastic limiter assembly is squeezed during the foaming process, the damper assembly can still be released by pressing. At the same time, the oblique sliding of the elastic limiter assembly not only limits the damper assembly, but also applies downward pressure to the damper assembly, making the damper assembly more firmly fixed.

[0009] Optionally, the telescopic direction of the elastic telescopic part is parallel to the inclined surface, and a side surface of the elastic telescopic part that can contact the damper assembly also includes a parallel surface, which is parallel to the upper side surface of the damper assembly and is arranged at one end of the inclined surface.

[0010] Optionally, the elastic limiting assembly also includes a base; a cavity is provided inside the base, and the mouth of the cavity faces the damper connecting piece, the elastic telescopic part can be movably arranged in the cavity of the base through the mouth of the cavity, and the mouth of the cavity is provided with a sliding surface, and the sliding surface corresponds to the side of the elastic telescopic part where the inclined surface is provided.

[0015] Optionally, the damper assembly includes a frame, a drive assembly and a damper plate; the frame is detachably arranged in the through slot, with one side abutting against the smaller opening of the air inlet end and the air outlet end; the drive assembly is arranged on one side of the frame to divide the frame into two channels; the damper plate includes a first plate body and a second plate body, which respectively cover the two channels and are both connected to the drive assembly to open or close the two channels.

[0016] Optionally, the area of ​​the first plate body is greater than the area of ​​the second plate body.

[0017] In some embodiments, a refrigerator includes: any of the above-mentioned damper fixing structures.

[0018] The damper fixing structure and refrigerator provided by the embodiments of the present disclosure can achieve the following technical effects:

[0019] The damper assembly is limited by an elastic limiting assembly with a certain adjustment amount, wherein the elastic telescopic part inside the elastic limiting assembly can extend toward the inside of the damper connecting piece under the action of elasticity, and the side that can contact the damper assembly is an inclined surface. Therefore, when limiting damper assemblies of different thicknesses, the elastic telescopic part can adjust its extended length by itself, so that the inclined surface can always be in contact with the damper assembly, thereby better limiting and fixing the damper assembly.

[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0039] Combination Figure 1 to Figure 2 As shown, in some embodiments, the damper fixing structure includes: a damper connector 100, a damper assembly 200 and an elastic limiting assembly 300; the damper connector 100 is provided with a through slot 110 for connecting the air duct; the damper assembly 200 is detachably arranged in the through slot 110; the elastic limiting assembly 300 is arranged on the side wall of the damper connector 100, and includes an elastic telescopic portion 310, which protrudes into the through slot 110 when the elastic telescopic portion 310 is extended, and is used to fix and limit the damper assembly 200, and when the elastic telescopic portion 310 is contracted, it is parallel to or recessed with the inner side wall of the through slot 110, and the fixed limit of the damper assembly 200 can be released, wherein a side of the elastic telescopic portion 310 that can contact the damper assembly 200 includes an inclined surface 311.

[0040] The damper fixing structure provided in the embodiment of the present disclosure is adopted, and the damper assembly 200 is limited by an elastic limiting assembly 300 with a certain adjustment amount, wherein the elastic telescopic portion 310 inside the elastic limiting assembly 300 can extend toward the inside of the damper connector 100 under the action of elasticity, and the side thereof that can contact the damper assembly 200 is an inclined surface 311. Therefore, when limiting the damper assemblies 200 of different thicknesses, the elastic telescopic portion 310 can adjust its extended length by itself, so that the inclined surface 311 can always be in contact with the damper assembly 200, so as to better limit and fix the damper assembly 200. Compared with the traditional solution of limiting the damper assembly 200 in a fixed position, the gap between the damper assembly 200 and the elastic telescopic portion 310 can be eliminated, thereby ensuring that the elastic telescopic portion 310 can maintain close contact with the damper assembly 200, avoiding the damper assembly 200 from shaking after installation, and improving the stability of the damper assembly 200.

[0041] It can be understood that in order to facilitate the description of various positions on the damper assembly 200, the following description is made by taking the damper assembly 200 being horizontally arranged inside the through slot 110 provided on the damper connector 100 as an example.

[0042] Optionally, the angle between the inclined surface 311 and the horizontal plane is greater than or equal to 10° and less than or equal to 30°. Preferably, the angle between the inclined surface 311 and the horizontal plane is 10°. In this way, as its extended length changes, a suitable position on the inclined surface 311 can be brought into contact with and squeezed against the upper end of the damper assembly 200, exerting downward pressure on the damper assembly 200, so that the damper assembly 200 is fixed more securely. Setting the inclination angle of the inclined surface 311 between 10° and 30° can maintain a sufficient adjustment amount to avoid a gap between the damper assembly 200 and the elastic telescopic portion 310, and can also avoid the inclination angle of the inclined surface 311 being too large to cause insufficient downward pressure, thereby maintaining a good limiting effect on the damper assembly 200.

[0043] Combination Figure 2 As shown, optionally, the telescopic direction of the elastic telescopic part 310 is parallel to the inclined surface 311, and one side of the elastic telescopic part 310 that can contact the damper assembly 200 also includes a parallel surface 312, which is parallel to the upper side of the damper assembly 200 and is arranged at one end of the inclined surface 311. In this way, the elastic telescopic part 310 can be obliquely telescoped along the inclined surface 311, and the parallel surface 312 located at one end of the inclined surface 311 is used to abut against the upper end of the damper assembly 200, so that the elastic telescopic part 310 increases the contact area with the damper assembly 200, and improves the fixing ability of the damper assembly 200.

[0044] Optionally, the parallel surface 312 and the inclined surface 311 are continuously arranged as a whole. In this way, the integrated structure can enable the parallel surface 312 and the inclined surface 311 to move synchronously, and the integrated structure can improve the overall structural strength and prevent the occurrence of fracture under the action of external force.

[0045] Combination Figures 3 to 4As shown, optionally, the elastic limit assembly 300 further includes a base 320; a cavity 321 is provided inside the base 320, and the mouth 322 of the cavity 321 faces the damper connector 100, and the elastic telescopic part 310 can be movably arranged in the cavity 321 of the base 320 through the mouth 322 of the cavity 321, and the mouth 322 of the cavity 321 is provided with a sliding surface 323, and the sliding surface 323 corresponds to the side of the elastic telescopic part 310 provided with the inclined surface 311. In this way, the cavity 321 inside the base 320 provides a accommodating space for the elastic telescopic part 310 when it is retracted; the sliding surface 323 cooperates with the inclined surface 311 to guide the moving path of the elastic telescopic part 310, ensuring that the elastic telescopic part 310 can always move along the inclined surface 311, avoiding it from deviating from the motion trajectory and reducing the guiding effect on the damper assembly.

[0046] It can be understood that the inclined surface 311 is disposed on the lower side of the elastic telescopic portion 310 , and the corresponding sliding surface 323 is disposed on the lower inner wall of the mouth 322 of the cavity 321 .

[0047] Combination Figure 5 As shown, optionally, a spring 330 is provided between the base 320 and the elastic telescopic portion 310, and one end of the spring 330 abuts against the base 320, and the other end abuts against the elastic telescopic portion 310. In this way, relying on the elasticity of the spring 330 itself, the elastic telescopic portion 310 can protrude from the through slot 110 without the action of other external forces, so that it abuts closely against the upper end of the damper assembly 200, thereby improving the fixing strength of the damper assembly 200.

[0048] Optionally, the movement direction of the elastic telescopic part 310 is parallel to the extension direction of the spring 330. In this way, the two can move synchronously in the same direction, and the uniformity of movement between the two enables the elastic telescopic part 310 to move smoothly. If the extension direction of the spring 330 is horizontal, which is inconsistent with the movement direction of the elastic telescopic part 310, the spring 330 will tilt or press down one end of the elastic telescopic part 310 toward the through groove 110 under its own elastic action, causing the elastic telescopic part 310 to excessively abut the contact position with the mouth 322 of the cavity 321 during the movement, causing the side wall of the mouth 322 and / or the side wall of the elastic telescopic part 310 to be excessively worn, thereby reducing the service life. At the same time, when the expansion direction of the spring 330 is inconsistent with the movement direction of the elastic telescopic part 310, the spring 330 will also bend to a certain extent, which will cause the elastic telescopic part 310 to jam during the movement.

[0049] Optionally, one end of the spring 330 is perpendicular to the side wall abutted by the base 320, and the other end is perpendicular to the side wall abutted by the elastic telescopic part 310. In this way, when the spring 330 is extended or compressed, the movement direction is consistent with that of the elastic telescopic part 310, and the spring 330 is also parallel to the inclined surface 311 and the sliding surface 323, so that the elastic telescopic part 310 can move stably.

[0050] Optionally, the contact surface between the base 320 and one end of the spring 330 is a first inclined surface, and the first inclined surface is perpendicular to the sliding surface 323; the contact surface between the elastic expansion part 310 and the other end of the spring 330 is a second inclined surface, and the second inclined surface is perpendicular to the inclined surface 311, wherein the first inclined surface is parallel to the second inclined surface. In this way, the movement direction of the spring 330 during expansion and contraction can be consistent with that of the elastic expansion part 310, and the stability of the abutment and fixation of the two ends of the spring 330 is improved.

[0051] Combination Figure 6 As shown, optionally, a limiting protrusion 313 is provided at one end of the elastic telescopic part 310 facing the base 320. In this way, since the limiting protrusions 313 are provided on the left and right sides of the elastic telescopic part 310, the width of the embedded end of the elastic telescopic part 310 is greater than the width of the mouth 322 of the cavity 321, so the elastic telescopic part 310 is not easy to escape from the mouth 322 of the cavity 321 without the help of external force, so that the elastic telescopic part 310 can operate stably.

[0052] Optionally, a slot 314 is provided at one end of the elastic expansion part 310 facing the base 320, dividing it into two parallel clamping plates 315, and a limiting protrusion is provided on both sides of the two clamping plates 315 facing the base 320. In this way, the clamping plates 315 have a certain elasticity, and an external force can be applied to the clamping plates 315 to squeeze the two clamping plates 315 toward the middle, so that the width of the limiting protrusion 313 is smaller than the width of the mouth 322 of the cavity 321, so that the elastic expansion part 310 can be easily taken out of the cavity 321 of the base 320.

[0053] Combination Figure 7 As shown, optionally, the outer peripheral wall of the damper connector 100 is provided with mutually cross-arranged transverse ribs 120 and longitudinal ribs 130. In this way, the overall structural strength of the damper connector 100 is improved by the cross-arranged transverse ribs 120 and longitudinal ribs 130, so that the through slot 110 of the damper connector 100 is not easily deformed under the action of external force, and the damper assembly 200 is more smoothly installed or removed.

[0054] Optionally, the transverse ribs 120 are parallel to the opening of the through slot 110 of the damper connector 100, surround the outer peripheral wall thereof, and are arranged at equal intervals. In this way, the transverse ribs 120 arranged at equal intervals increase the upper limit of the longitudinal force of the damper connector 100 under the action of external force.

[0055] Optionally, the longitudinal ribs 130 are arranged perpendicular to the transverse ribs 120 and are arranged at equal distances. In this way, the longitudinal ribs 130 make up for the lack of transverse compressive strength of the transverse ribs 120 under external force, so that the overall strength of the damper connector 100 is improved.

[0056] Combination Figure 8 As shown, optionally, the damper connector 100 further includes an air inlet end and an air outlet end, and the opening of one of them is smaller than the opening of the other. In this way, the smaller opening is located at the lower end of the damper connector 100, and the size of the inner peripheral wall of the opening is smaller than the size of the outer peripheral wall of the damper assembly 200, so that it can limit one side of the damper assembly 200, prevent the damper assembly 200 from escaping from the through slot 110, and make the operation of the damper assembly 200 more stable.

[0057] Optionally, the lower end of the damper connector 100 is the air inlet, and the upper end of the damper connector 100 is the air outlet, wherein the opening of the air inlet is smaller than the opening of the air outlet. In this way, the air inlet with a smaller opening than the air outlet increases the air supply pressure and also increases the air flow rate from the air inlet to the air outlet.

[0058] Optionally, a rectangular hole 140 is provided on the side wall of the damper connector 100, which is only used for the elastic expansion part 310 to pass through. In this way, since the size of the rectangular hole 140 is smaller than the size of some components of the elastic limiting assembly 300, the components of the elastic limiting assembly 300 that are larger than the size of the rectangular hole 140 are restricted, so that they cannot pass through the rectangular hole 140 and enter the through slot 110.

[0059] It is understandable that when the elastic telescopic part 310 is in the contracted state, its end facing the through slot 110 can be completely retracted into the rectangular hole 140 so that it does not protrude from the side of the rectangular hole 140 facing the through slot 110 and does not affect the removal of the damper assembly 200.

[0060] Combination Fig. 9 As shown, optionally, the damper assembly 200 includes a frame 210, a drive assembly 220 and a damper plate 230; the frame 210 is detachably arranged in the through slot 110, and one side is abutted against the smaller opening of the air inlet end and the air outlet end; the drive assembly 220 is arranged on one side of the frame 210, and the frame 210 is divided into two channels; the damper plate 230 includes a first plate body 231 and a second plate body 232, which cover the two channels respectively, and are both connected to the drive assembly 220, and can open or close the two channels. In this way, the damper assembly 200 can control the opening and closing of the first plate body 231 or the second plate body 232 separately through the drive assembly 220, so that the damper assembly 200 can supply air to two different channels, so that the damper assembly 200 is suitable for different work requirements.

[0061] Optionally, the two channels include a first air duct 211 and a second air duct 212, wherein the opening of the first air duct 211 is larger than the opening of the second air duct 212. In this way, the damper assembly 200 can supply air to different areas through the first air duct 211 and / or the second air duct 212, thereby improving the applicability of the damper assembly 200.

[0062] Optionally, the inner wall of the frame 210 and the outer wall of the driving assembly 220 are respectively provided with hinge columns, and the axes of these hinge columns overlap each other. In this way, the first plate 231 and / or the second plate 232 can be arranged at the same installation height, so that the driving assembly 220 can control the first plate 231 and / or the second plate 232 without changing its structure, thereby improving the versatility of the driving assembly 220.

[0063] Combination Fig. 9 As shown, optionally, the area of ​​the first plate 231 is greater than the area of ​​the second plate 232. The first plate 231 is arranged corresponding to the first air duct 211, and the second plate 232 is arranged corresponding to the second air duct 212. In this way, the first plate 231 and the second plate 232 can fully shield the first air duct 211 and the second air duct 212 respectively when closed, thereby improving the airtightness of the first plate 231 and the second plate 232 and reducing the occurrence of air leakage due to poor shielding.

[0064] Optionally, a rubber ring is provided on one side of the first plate 231 and / or the second plate 232 facing the frame 210. In this way, the sealing between the damper plate 230 and the first air duct 211 and / or the second air duct 212 can be further improved to prevent air leakage in the non-air supply stage.
