Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, and particularly to an air pump assembly structure, a refrigerating and freezing device, and a refrigerator. Background Art

[0002] In a PSA (Pressure Swing Adsorption) nitrogen generation system, a vibration damping structure is usually provided at the air pump. Specifically, the air pump box is directly fixed in the refrigeration foam layer. The air pump box is provided with four mounting posts, and a vibration damping pad is installed at each mounting post. The mounting post is connected to the air pump support plate through the vibration damping pad, and the air pump is fixed to the support plate, and the support plate is fixed to the air pump box. With such a setting, although the vibration generated when the air pump works can be absorbed by the vibration damping pad, there will still be some vibrations transmitted to the air pump box through the support plate and transmitted to the foam layer through the air pump box, resulting in loose fixing between the air pump box and the foam layer. Summary of the Utility Model

[0003] Based on this, it is necessary to provide an air pump assembly structure that can effectively reduce the vibration influence when the air pump works.

[0004] An air pump assembly structure includes an air pump box, a first vibration damping component, and a second vibration damping component: the air pump box includes a box body and a box cover, which are snap-fitted together to jointly enclose an assembly cavity; the first vibration damping component is disposed in the assembly cavity and is configured with an assembly space for limiting the air pump; the second vibration damping component is installed outside the air pump box for connecting a target assembly component.

[0005] It can be understood that the assembly space configured by the first vibration damping component is used for installing the air pump, and since the first vibration damping component is installed in the assembly cavity of the air pump box. Therefore, when the air pump is installed, the first vibration damping component is equivalent to being installed between the air pump and the air pump box. The vibration generated when the air pump works is absorbed and damped once by the first vibration damping component, reducing the vibration transmitted to the air pump box. At the same time, since the second vibration damping component is provided outside the air pump box and the air pump box is connected to the target assembly component by using the second vibration damping component, the vibration transmitted from the air pump to the air pump box can also be absorbed and damped twice by the second vibration damping component, reducing the vibration transmitted to the target assembly component and ensuring the connection reliability between the air pump box and the target assembly component.

[0006] In some embodiments, the first vibration damping component includes at least two vibration damping members having receiving grooves, and at least two of the vibration damping members jointly define the assembly space, at least one of the vibration damping members is disposed on the box body, and at least another vibration damping member is disposed on the box cover.

[0007] In some of these embodiments, the box body is detachably connected to the corresponding shock absorber, and / or, the box cover is detachably connected to the corresponding shock absorber.

[0008] In some of these embodiments, the box cover corresponds to an upper shock absorber. One of the upper shock absorber and the box cover protrudes with a limiting rib, and the other is provided with a limiting notch. The limiting rib is clamped at the limiting notch; and / or, the box body corresponds to a lower shock absorber. One of the lower shock absorber and the box body protrudes with an assembly post, and the other is recessed with an assembly hole. The assembly post is inserted into the assembly hole.

[0009] In some of these embodiments, each shock absorber protrudes with a constraint portion at the groove wall of the corresponding accommodating groove. The constraint portion is used to abut against the air pump.

[0010] In some of these embodiments, the air pump box has a central axis; the second shock-absorbing member includes at least two shock-absorbing blocks arranged at intervals around the central axis. Each shock-absorbing block is connected to the air pump box and is used to connect a target assembly component.

[0011] In some of these embodiments, one of the second shock-absorbing member and the air pump box is provided with an assembly protrusion, and the other is provided with an assembly card slot. The assembly protrusion is inserted into the assembly card slot.

[0012] This application also provides a refrigeration and freezing device, including a mounting plate and the above-mentioned air pump assembly structure. The mounting plate is provided with an assembly groove, and the second shock-absorbing member in the air pump assembly structure is clamped in the assembly groove.

[0013] In some of these embodiments, at least two hanging arms arranged at intervals protrude from one side of the mounting plate along its thickness direction. Each of the hanging arms surrounds the assembly groove, and each shock-absorbing block in the second shock-absorbing member is correspondingly clamped in one assembly groove.

[0014] This application also provides a refrigerator, including a cabinet body and the above-mentioned refrigeration and freezing device. The refrigeration and freezing device is arranged in the cabinet body. BRIEF DESCRIPTION OF THE DRAWINGS

The term "and / or" used in the specification of the present application includes any and all combinations of one or more of the related listed items.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 12, an embodiment of the present application provides an air pump assembly structure 100, which can effectively reduce the vibration influence during the operation of the air pump 300. Specifically, the air pump assembly structure 100 includes an air pump box 110, a first damping component 120, and a second damping component 130. The air pump box 110 includes a box body 111 and a box cover 112, which are snap-fitted together to jointly enclose an assembly cavity 1101. The first damping component 120 is disposed in the assembly cavity 1101 and is configured with an assembly space (not shown in the figure) for limiting the air pump 300. The second damping component 130 is installed outside the air pump box 110 and is used to connect the target assembly component.

[0035] It can be understood that the air pump 300 can be installed in the assembly space configured by the first damping component 120. And since the first damping component 120 is installed in the assembly cavity 1101 of the air pump box 110, it is equivalent to installing the air pump 300 in the air pump box 110. That is to say, the air pump 300 is installed in the air pump box 110 through the first damping component 120, and the first damping component 120 is installed between the air pump 300 and the air pump box 110. Therefore, the vibration generated during the operation of the air pump 300 can be absorbed and damped once by the first damping component 120, reducing the vibration transmitted to the air pump box 110. At the same time, since the second damping component 130 is provided outside the air pump box 110 and the air pump box 110 is connected to the target assembly component by using the second damping component 130, the vibration transmitted from the air pump 300 to the air pump box 110 through the first damping component 120 can also be absorbed and damped twice by the second damping component 130, reducing the vibration transmitted to the target assembly component and ensuring the connection reliability between the air pump box 110 and the target assembly component.

[0036] Among them, the target assembly component here can be a refrigeration foaming layer, and of course it can also be other structures for installing the air pump 300. In the following, the mounting plate 200 is used as the target assembly component in the refrigeration and freezing device.

[0037] Taking the target assembly component as the mounting plate 200 as an example, the specific structures of the first damping component 120 and the second damping component 130 will be described in detail below.

[0038] Please refer to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 12, in some embodiments, the first damping member 120 includes at least two damping members 121 having receiving grooves 1210. The at least two damping members 121 jointly define an assembly space, and at least one damping member 121 is disposed in the box body 111, and at least another damping member 121 is disposed in the box cover 112. In this way, it is equivalent to that the air pump 300 is correspondingly provided with the damping members 121 relative to both the box body 111 and the box cover 112, so as to fully absorb vibration (hereinafter referred to as vibration absorption), and thus achieve the damping effect.

[0039] In actual use, the box cover 112 and the box body 111 are both correspondingly provided with cavities 1102. When the box cover 112 and the box body 111 are fastened, the two cavities 1102 jointly form an assembly cavity 1101. Among them, the box cover 112 and the box body 111 can be fixed by screws. Taking the two damping members 121 as an example, the two damping members 121 can be arranged relatively and at intervals. One of the damping members 121 is installed in the cavity 1102 of the box body 111, and the other damping member 121 is installed in the cavity 1102 of the box cover 112, and then they are jointly fastened outside the air pump 300. Of course, it can also be that one of the damping members 121 is fastened to the upper position of the air pump 300 through the corresponding receiving groove 1210, and the other damping member 121 is fastened to the lower position of the air pump 300 through the corresponding receiving groove 1210, and then the box body 111 and the box cover 112 are respectively fastened outside the corresponding damping members 121.

[0040] As Figure 5 shown, further, since the air pump 300 is installed between the upper and lower relatively spaced damping members 121, a constraint portion 1211 can be protrudingly provided at the groove wall of the corresponding receiving groove 1210 of each damping member 121, and the constraint portion 1211 abuts against the air pump 300. It can be understood that by providing the constraint portion 1211, it is used to cooperate with the air pump 300 to improve the connection reliability between each damping member 121 and the air pump 300, and prevent the damping member 121 from loosening due to vibration when the air pump 300 is working. Of course, if the air pump 300 itself has a concave area, the constraint portion 1211 can be protrudingly provided on the damping member 121 corresponding to the concave area.

[0041] Among them, a smooth transition can be made between each constraint portion 1211 and the groove wall of the corresponding receiving groove 1210 to reduce the wear between the air pump 300.

[0042] Please continue to refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 12Optionally, the vibration damper 121 corresponding to the box body 111 is an upper vibration damper 121a, and the upper vibration damper 121a is buckled at the upper position of the air pump 300 through the corresponding receiving groove 1210. The vibration damper 121 corresponding to the box cover 112 is a lower vibration damper 121b, and the lower vibration damper 121b is buckled at the lower position of the air pump 300 through the corresponding receiving groove 1210. The box body 111 is detachably connected to the upper vibration damper 121a, and the box cover 112 is detachably connected to the lower vibration damper 121b. Such a setting facilitates the disassembly and assembly of the upper vibration damper 121a and the lower vibration damper 121b relative to the box cover 112 and the box body 111, respectively, so as to facilitate the replacement of the corresponding vibration damper 121. Of course, only the box body 111 can be detachably connected to the upper vibration damper 121a, or only the box cover 112 can be detachably connected to the lower vibration damper 121b.

[0043] Specifically, one of the upper damping member 121a and the box cover 112 is provided with a convex limiting rib 141, and the other is provided with a limiting notch 142, and the limiting rib 141 is clamped at the limiting notch 142; at the same time, one of the lower damping member 121b and the box body 111 is provided with a convex assembly column 151, and the other is provided with a concave assembly hole 152, and the assembly hole 152 is inserted into the assembly hole 152. In other words, as far as the box cover 112 and the upper damping member 121a are concerned, the limiting rib 141 and the limiting notch 142 are used to achieve a detachable connection between the two; and as far as the box body 111 and the lower damping member 121b are concerned, the assembly column 151 and the assembly hole 152 are used to achieve a detachable connection between the two.

[0044] like Figure 2 , Figure 3 , Figure 4 and Figure 12 As shown, in some specific embodiments, the upper damping member 121a includes a first groove portion 1212 and a first connecting portion 1213 connected to the groove portion, and the first groove portion 1212 is concavely provided with a corresponding accommodation groove 1210. The first groove portion 1212 is also configured with an avoidance hole connected to the corresponding accommodation groove 1210, and the lines on the air pump 300 can be passed through the avoidance hole. The connecting portion 1213 is connected to the first groove portion 1212 away from the corresponding notch. The connecting portion 1213 includes two connecting arms (not shown in the figure) that are opposite and spaced apart, for example, spaced along the Y-axis direction, and each connecting arm is provided with a limited notch 142 on both sides along the X-axis direction. The box cover 112 is convexly provided with a limiting rib 141 on the cavity wall of the corresponding concave cavity 1102, and the limiting rib 141 is clamped at the limiting notch 142, and the lower surface of the limiting rib 141 abuts against the upper surface of the limiting notch 142. In addition, a reinforcing rib 1215 may be protruded from one side opposite to each connecting arm to improve the structural strength of the corresponding connecting arm.

[0045] like Figure 2 , Figure 5 ,Figure 6 and Figure 12 As shown in Figure 12 , in another specific embodiment, the lower damping member 121b includes a second groove portion 1214, and a corresponding accommodating groove 1210 is recessed in the second groove portion 1214. The assembly post 151 protrudes from a side of the second groove portion 1214 away from the corresponding notch, that is, protrudes from the bottom of the second groove portion 1214, and extends in a direction away from the upper damping member 121a. The box body 111 is recessed with an assembly hole 152 at the bottom of the corresponding cavity 1102 in a direction away from the box cover 112. The assembly post 151 is inserted into the assembly hole 152, and thus the detachable connection between the lower damping member 121b and the box body 111 can be realized. For example, an installation protrusion 153 protrudes from the bottom of the cavity, and an assembly hole 152 is recessed at an extending end of the installation protrusion 153 in a direction away from the upper damping member 121a. At the same time, a plurality of clamping plates 154 arranged at intervals around the axis of the assembly hole 152 can be arranged in the assembly hole 152 to cooperate with the assembly post 151 for limiting.

[0046] Wherein, a plurality of assembly posts 151 are provided and arranged at intervals, and correspondingly a plurality of assembly holes 152 are also provided. Each assembly post 151 corresponds to an assembly hole 152, which improves the connection reliability between the lower damping member 121b and the box body 111. For example, three, four, six, eight, etc. assembly posts 151 are provided, and the number of assembly holes 152 is adapted accordingly. At the same time, the assembly post 151 can be a cylinder, and the corresponding assembly hole 152 is a round hole. Or, the assembly post 151 is a square post, and the corresponding assembly hole 152 is a square hole. Only examples are given here. In actual use, the extending ends of the respective assembly posts 151 are provided in a hemispherical shape, which is convenient for inserting into the corresponding assembly holes 152.

[0047] Alternatively, it can also be that the box body 111 protrudes with an assembly post 151 on the bottom of the corresponding cavity 1102 toward the side close to the box cover 112, and the lower damping member 121b is recessed with an assembly hole 152 on a side away from the upper damping member 121a, as long as the detachable connection between the lower damping member 121b and the box body 111 can be realized by the plug-in fit between the assembly post 151 and the assembly hole 152.

[0048] In other embodiments, the number of damping members 121 in the first damping component 120 can also be set to three, four, etc., as long as an assembly space can be jointly surrounded by the corresponding accommodating grooves 1210 of the plurality of damping members 121, so that each damping member 121 is installed between the air pump 300 and the air pump box 110 to achieve primary vibration absorption.

[0049] Please refer to Figure 1 and Figure 12, in another embodiment, the air pump box 110 has a central axis, for example, along the Z-axis direction. The second damping member 130 includes at least two damping blocks 131 arranged at intervals around the central axis. Each damping block 131 is connected to the air pump box 110 and is used to connect the mounting plate 200. In this way, on the one hand, it is equivalent to having multiple connection points arranged at intervals between the air pump box 110 and the mounting plate 200, improving the connection reliability between the two; on the other hand, it is equivalent to having multiple damping blocks 131 between the air pump box 110 and the mounting plate 200, improving the damping effect. For example, it can include two damping blocks 131 that are opposite and spaced apart along the X-axis direction.

[0050] As Figure 1 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 12 shown, wherein the connecting pipeline 310 on the air pump 300 can extend out through a box cover 112. At this time, the box cover 112 is configured with a through hole for the box cover 112 to pass through. The box cover 112 is closer to the mounting plate 200 than the box body 111. Therefore, each damping block 131 is connected to the box cover 112. Specifically, at least two assembly protrusions 161 arranged at intervals around the central axis can be convexly provided on the outer side of the box cover 112. Then, each damping block 131 is configured with an assembly card slot 162, and each damping block 131 corresponds to an assembly protrusion 161, and the assembly card slot 162 is used to be snap-fitted with the corresponding assembly protrusion 161 to realize the assembly of each damping block 131 relative to the box cover 112.

[0051] Alternatively, it can also be that each damping block 131 is convexly provided with an assembly protrusion 161, while the box cover 112 is concavely provided with an assembly card slot 162. As long as the assembly of each damping block 131 relative to the box cover 112 is realized by the cooperation of the assembly protrusion 161 and the assembly card slot 162, and then the air pump box 110 is reliably connected to the mounting plate 200 by the damping block 131.

[0052] During actual use, the through hole for the connecting pipeline 310 to pass through can be arranged to penetrate one of the assembly protrusions 161. Therefore, the assembly card slot 162 on the damping block 131 corresponding to this assembly protrusion 161 is arranged to penetrate, for the connecting pipeline 310 to lead out.

[0053] In other embodiments, the number of damping blocks 131 can also be set to three, four, etc. As long as it can be connected to the mounting plate 200 through multiple damping blocks 131 to achieve secondary vibration absorption.

[0054] In some embodiments, each of the aforementioned damping members 121 and each damping block 131 are made of rubber material, silicone material, etc.

[0055] Please refer toFigures 10 to 12 , Another embodiment of the present application provides a refrigeration and freezing device, including a mounting plate 200 and the above-mentioned air pump assembly structure 100. The mounting plate 200 is provided with an assembly groove 201, and the second vibration damping member 130 in the air pump assembly structure 100 is clamped in the assembly groove 201, that is, each vibration damping block 131 is clamped and matched with the assembly groove 201, and the number of the assembly grooves 201 is adapted to the number of the vibration damping blocks 131.

[0056] Further, at least two suspension arms 210 spaced apart around the central axis are convexly provided on one side of the mounting plate 200 along its thickness direction, and each suspension arm 210 is provided with an assembly groove 201 around it. Each vibration damping block 131 in the second vibration damping member 130 is correspondingly clamped in an assembly groove 201. The suspension arm 210 can be arranged in a U shape, including a cross arm and two vertical arms connected to both sides of the cross arm, and each vertical arm is fixed to the mounting plate 200. The two vertical arms and the cross arm jointly enclose the assembly groove 201, and the vibration damping block 131 is inserted into the corresponding assembly groove 201 and lapped on the corresponding suspension arm 210, realizing the suspension of the air pump assembly structure 100 relative to the mounting plate 200.

[0057] In some specific embodiments, vibration damping blocks 131 are respectively connected to both sides of the air pump box 110 along the X-axis direction, and each vibration damping block 131 corresponds to an assembly groove 201 surrounded by a suspension arm 210.

[0058] Alternatively, it may also be that a mounting block is convexly provided on one side of the mounting plate 200 along its thickness direction, and each mounting block is recessed with an assembly groove 201 for cooperating with the vibration damping block 131. As long as it can realize the stable connection of the air pump assembly structure 100 to the mounting plate 200 through the assembly block and achieve secondary vibration absorption.

[0059] During actual use, structures such as pipelines, valve parts, and molecular sieve towers for nitrogen production can be installed on the mounting plate 200. Therefore, by combining the aforementioned first vibration damping member 120 and second vibration damping member 130, the vibration transmitted from the air pump 300 to the mounting plate 200 is reduced, avoiding affecting other components. Moreover, due to the setting of the mounting plate 200, it is equivalent to integrally assembling the air pump 300, pipelines, valve parts, and molecular sieve tower to form an overall structure, which is convenient for assembly and disassembly relative to other structures.

[0060] Another embodiment of the present application provides a refrigerator, including a cabinet body and the above-mentioned refrigeration and freezing device, and the refrigeration and freezing device is installed in the cabinet body. During actual use, the refrigerator further includes a door body, and the door body is rotatably connected to the cabinet body through a hinge. The refrigeration and freezing device is configured with a liner cavity for storing ingredients to be refrigerated or frozen, etc., to achieve ingredient preservation.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
