Referring to fig. 8 and 9 in combination, fig. 8 is an enlarged schematic view of a region a in fig. 5, and fig. 9 is a schematic view of a connection structure between the second mounting portion 1212 and the compressor capacitor 140.

The second mounting portion 1212 is provided with a socket 160 having an opening at one end, and the opening end of the socket 160 extends out of the box body through the bottom plate 1111 along the third direction, and the fixed end 141 of the compressor capacitor 140 is plugged with the socket 160. Compared with the prior art in which the compressor capacitor 140 is fixed by using a binding belt or a hoop, in this embodiment, the assembly of the compressor capacitor 140 is more convenient and quick, and is time-saving and labor-saving.

In order to ensure that the fixed end 141 of the compressor capacitor 140 can be reliably fixed in the socket barrel 160, in this embodiment, a limiting ring wall 1411 is convexly arranged on the side wall of the fixed end 141, a second elastic buckle 161 is arranged on the side wall of the socket barrel 160, and the second elastic buckle 161 abuts against one side of the limiting ring wall 1411 away from the end wall of the fixed end 141.

It is understood that the second elastic buckle 161 protrudes from the sidewall of the socket 160 before the fixed end 141 of the compressor capacitor 140 is inserted into the socket 160. In the process of inserting the compressor capacitor 140 into the plug cylinder 160, the limiting ring wall 1411 firstly extrudes and pushes the second elastic buckle 161 to deform so as to withdraw from the plug cylinder 160, and when the limiting ring wall 1411 is continuously inserted to pass over the second elastic buckle 161, the second elastic buckle 161 releases elastic potential energy and enables one side of the limiting ring wall 1411, which is away from the end wall of the fixed end 141, to abut against the end wall, thereby preventing the compressor capacitor 140 from withdrawing from the plug cylinder 160 and ensuring the reliable fixation of the compressor capacitor 140 in the plug cylinder 160.

In order to ensure the effect of the holding limitation, in this embodiment, the number of the second elastic buckles 161 is two, and the two second elastic buckles 161 are disposed at two opposite ends of the socket 160 in the same radial direction. In other embodiments, the number of the second elastic buckles 161 may be adjusted to be multiple according to the real-time application condition, and the multiple second elastic buckles 161 are uniformly distributed in the circumferential direction of the socket 160.

In this embodiment, the second elastic buckle 161 has a holding end 1611 and a connecting end 1612 that are disposed opposite to each other, the connecting end 1612 is connected to a side wall of the socket 160, the holding end 1611 is suspended and held against the limiting wall 1411, and the holding end 1611 is closer to the bottom wall of the socket 160 than the connecting end 1612.

It can be appreciated that, during the gradual insertion of the compressor capacitor 140 into the socket 160, the limiting ring 1411 gradually moves from the connecting end 1612 of the second elastic buckle 161 toward the abutting end 1611, and during this process, the second elastic buckle 161 pushing the cantilever structure deforms, so that the abutting end 1611 swings in a direction away from the axis of the socket 160. When the limit ring 1411 is inserted further beyond the abutting end 1611, the second elastic buckle 161 releases elastic potential energy to drive the abutting end 1611 to move towards the direction approaching the axis of the plug tube 160 for resetting, and the abutting end 1611 abuts against the limit ring 1411 after resetting is completed.

In order to facilitate deformation of the second elastic buckle 161, in this embodiment, a first avoidance hole 1613 is formed in a sidewall of the socket 160 in a penetrating manner, the connecting end 1612 is connected with a hole wall of the first avoidance hole 1613 on one side close to an opening of the socket 160, and the second elastic buckle 161 is configured to drive the abutting end 1611 to rotate in a direction away from an axis of the socket 160 from the first avoidance hole 1613 under the pushing of the limiting ring 1411.

In practice, the second elastic buckle 161 and the socket 160 are integrally formed, and the second elastic buckle 161 may be formed by punching a solid area on the sidewall of the socket 160 corresponding to the first avoidance hole 1613, so that the first avoidance hole 1613 is formed while the second elastic buckle 161 is formed.

The second elastic buckle 161 is provided with a sliding guide surface 1614 and a bonding surface 1615 on one side of the second elastic buckle 161, which is close to the axis of the plug tube 160, and the sliding guide surface 1614 and the bonding surface 1615 are sequentially arranged from the connecting end 1612 to the supporting end 1611, one side of the sliding guide surface 1614 is connected with one side of the bonding surface 1615 in an included angle and in smooth transition, and the bonding surface 1615 is bonded with the side wall of the compressor capacitor 140.

The connection corner of the sliding guide surface 1614 and the bonding surface 1615 extends into the socket 160, and in the process of gradually inserting the compressor capacitor 140 into the socket 160, the limit ring 1411 of the compressor capacitor 140 slides along the sliding guide surface 1614 to the corner first, in the process, the second elastic buckle 161 is pushed to deflect, and the sliding guide surface 1614 plays a role in guiding the insertion process of the compressor capacitor 140, so that the smooth insertion process is ensured. During the process of the limit-ring-wall 1411 passing over the corner and sliding on the abutment surface 1615, the second elastic catch 161 is no longer deflected and there is a gap between the abutment surface 1615 and the outer side wall of the compressor capacity 140. Until the limit ring 1411 slides out of the contact surface 1615, the second elastic buckle 161 deflects and returns to the contact surface 1615 to contact with the side wall of the compressor capacitor 140, and the abutting end 1611 abuts against the limit ring 1411.

In order to facilitate the connection of the compressor capacitor 140, in this embodiment, a connection member is protruding from an end wall of the fixed end 141, and a first yielding hole is formed in a bottom wall of the socket 160, through which the connection member passes. In fact, the PCB130 is disposed on the side of the mounting plate 121 opposite to the opening direction of the socket 160, that is, the wiring member protruding from the end wall of the fixed end 141 passes through the first relief hole to reach the same side of the PCB130, so that subsequent wiring of subsequent wiring members is facilitated.

In this embodiment, the compressor capacitor 140 is cylindrical, and the socket 160 is a cylindrical cavity with an opening at one end. In order to prevent the compressor capacitor 140 from rolling in the socket 160, in this embodiment, a plurality of stop ribs are disposed on the inner sidewall of the socket 160, and radially abut against the outer sidewall of the compressor capacitor 140.

Referring to fig. 10 and 11 in combination, fig. 10 is an enlarged schematic view of a region B in fig. 4, and fig. 11 is an enlarged schematic view of a region C in fig. 5.

A plurality of folded edges are vertically arranged on one side of the mounting plate body 121, a mounting cavity is formed by the plurality of folded edges and the mounting plate body 121, and the PCB130 is accommodated in the mounting cavity; the plurality of folds include a first fold 170 and a second fold 180 which are oppositely arranged in a second direction, a third elastic buckle 171 is arranged on the first fold 170, a second fixed buckle 181 is arranged on the second fold 180, the second fixed buckle 181 stretches into the mounting cavity along a direction parallel to the mounting plate body 121, and the second fixed buckle 181 and the third elastic buckle 171 respectively stop two opposite sides of one side of the PCB130, which is away from the mounting plate body 121.

In the process of assembling the PCB130, one side of the PCB130 is first embedded into the second fixing buckle 181 provided on the second flange 180 and is close to one side of the mounting board body 121, and then the PCB130 is gradually flattened, in this process, one side of the PCB130 away from the second fixing buckle 181 is gradually pressed and pushes the third elastic buckle 171 to deflect in a direction away from the second flange 180, and in this process, the third elastic buckle 171 accumulates elastic potential energy. Until one side of the PCB130 away from the second fixing buckle 181 passes over the third elastic buckle 171, the third elastic buckle 171 releases elastic potential energy and resets, the third elastic buckle 171 stretches into the mounting cavity again, and stops one side of the PCB130 away from the second fixing buckle 181, namely, the assembly of the PCB130 on the PCB bracket 120 is completed.

In this embodiment, the number of the third elastic buckles 171 and the second fixing buckles 181 is two, the two third elastic buckles 171 are arranged on the first folded edge 170 at intervals along the first direction, and the two second fixing buckles 181 are arranged on the second folded edge 180 at intervals along the second direction, so as to ensure reliable fixing of the PCB130. In other embodiments, the number of the third elastic buckle 171 and the second fixing buckle 181 may be adjusted to be multiple according to practical application conditions.

In fact, the first flange 170 and the second flange 180 realize stop limits on two opposite sides of the PCB130 in the second direction, and the third elastic buckle 171, the second fixing buckle 181 and the mounting board body 121 realize stop limits on two opposite sides of the PCB130 in the third direction. In order to ensure the limitation of the PCB130 in the first direction, in this embodiment, the multiple folds further include a third fold and a fourth fold, where the third fold and the fourth fold realize the limitation of the stops on two opposite sides of the PCB130 in the first direction, and the first fold 170, the second fold 180, the third fold, the fourth fold and the mounting plate 121 together enclose a mounting cavity.

The third elastic buckle 171 extends along the depth direction of the mounting cavity, the third elastic buckle 171 has a movable end and a fixed end 141 which are oppositely arranged, the fixed end 141 is connected with the first folded edge 170, and compared with the fixed end 141, the movable end is closer to the mounting plate body 121, and the movable end is suspended and stops the PCB130.

It will be appreciated that after one side of the PCB130 is embedded under the second fixing buckle 181, in the process of gradually flattening the PCB130, one side of the PCB130 away from the second fixing buckle 181 is gradually moved toward the movable end by the fixed end 141 of the third elastic buckle 171, and in this process, the third elastic buckle 171 is gradually deformed, so that the movable end swings toward a direction away from the second flange 180. When the side of the PCB130 away from the second fixing buckle 181 passes over the movable end, the third elastic buckle 171 releases elastic potential energy to drive the movable end to move above the PCB130 in the direction close to the second flange 180, so as to realize a stop for the side of the PCB130 away from the mounting plate 121.

In order to ensure that the third elastic buckle 171 can swing smoothly in the process, the first flange 170 is provided with a second avoidance hole 1711 in a penetrating manner, the fixed end 141 is connected with a hole wall of one side of the second avoidance hole 1711 away from the mounting plate body 121, and the third elastic buckle 171 is used for driving the movable end to exit from the mounting cavity from the second avoidance hole 1711 under the pushing of the PCB130 in the process of embedding the PCB130 into the mounting cavity.

In fact, the third elastic buckle 171 and the first flange 170 are integrally formed, the third elastic buckle 171 may be formed by punching the first flange 170, and the second avoiding hole 1711 may be formed at the same time of forming the third elastic buckle 171.

In order to ensure that the PCB130 can smoothly pass through the third elastic buckle 171 and be embedded into the mounting cavity, in this embodiment, a sliding guiding inclined plane 1712 is disposed on a side of the third elastic buckle 171, which is close to the second flange 180, from the fixed end 141 to the movable end, and the sliding guiding inclined plane 1712 gradually approaches the second flange 180.

In the process of gradually flattening the PCB130, one side of the PCB130 away from the second fixing buckle 181 slides on the sliding guiding inclined plane 1712, in this process, the third elastic buckle 171 is acted by a force towards a direction away from the second folded edge 180, so that the third elastic buckle 171 rotates from the second avoiding hole 1711 to gradually exit the mounting cavity, and after the PCB130 slides out of the sliding guiding inclined plane 1712, the third elastic buckle 171 resets and stops limiting one side of the PCB130 away from the mounting plate.

In order to improve the structural strength of the third elastic buckle 171, in this embodiment, a U-shaped reinforcing rib is vertically disposed on a side of the third elastic buckle 171 near the second flange 180, and the sliding guiding inclined plane 1712 is disposed on a side of the reinforcing rib near the second flange 180.

In addition, in order to ensure the assembly stability of the PCB130, the PCB130 is prevented from shaking in the mounting cavity to loosen components on the PCB130, in this embodiment, a supporting portion is further protruding on a side of the mounting plate body 121 corresponding to the multiple folds, the supporting portion abuts against a side of the PCB130 near the mounting plate body 121, and the third elastic buckle 171 and the second fixing buckle 181 both abut against a side of the PCB130 far away from the mounting plate body 121. In other words, in a state where the PCB130 is completely assembled, the PCB130 is clamped and fixed by the support portion, the third elastic buckle 171, and the second fixing buckle 181.

In this embodiment, the fan capacitor 150 is fixedly connected to the base plate 1111 by a threaded connection, specifically, a second mounting hole 1117 is provided in an area of the base plate 1111 corresponding to the yielding gap 1213, and a second mating hole 151 is correspondingly provided on the fan capacitor 150, where the second mating hole 151 mates with the second mounting hole 1117 through the threaded connection. Similarly, the threaded connection is a screw that is threaded through the second mating hole 151 into the second mounting hole 1117 to complete the attachment of the fan capacitor 150 to the base plate 1111.

Referring to fig. 12 in combination, fig. 12 is a schematic view of a portion of the structure of the middle partition 210.

For the installation and fixation of the dehumidifier 200 capacitor on the middle partition 210, the middle partition 210 is provided with an installation wall 211 and an installation recess 212 recessed towards the direction far away from the box body relative to the installation wall 211, the bottom plate 1111 is connected with the installation wall 211 through a threaded connector, and one end of the compressor capacitor 140 far away from the fixed end 141 is embedded into the installation recess 212.
