DETAILED DESCRIPTION

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 FIG. 2 is a schematic diagram of the structure of the dehumidifier 200 provided in this embodiment. Figure 2 Shown is an exploded schematic diagram of the dehumidifier 200 .

[0051] The dehumidifier 200 provided in this embodiment includes components such as a housing 230, a middle partition 210, a water tank 220, a compressor 240, a wind wheel 250, a condenser 260, an evaporator 270, and a dehumidifier electronic control box 100. The housing 230 includes a front panel 231, a rear panel 232, and a top cover 233. The front panel 231 and the rear panel 232 are respectively arranged on both sides of the middle partition 210 in the front-to-back direction, and enclose a space with an open top, and the top cover 233 covers the space from above. The water tank 220 is arranged at the lower part of the front panel 231, and the dehumidifier electronic control box 100 is arranged on the middle partition 210, and the water tank 220 and the dehumidifier electronic control box 100 are respectively located on both sides of the middle partition 210 in the front-to-back direction. The compressor 240 is disposed on the middle partition plate 210, and the wind wheel 250, the condenser 260 and the evaporator 270 are disposed in the space between the middle partition plate 210 and the top cover plate 233. The compressor 240 is connected to the condenser 260 and the evaporator 270 through a refrigerant circulation pipeline. The rear panel 232 is provided with an air inlet grille, and the top cover plate 233 is provided with an air outlet grille.

[0052] In actual application, the wind wheel 250 rotates, sucking in external air from the air inlet grille on the rear panel 232, and passing through the condenser 260 and the evaporator 270 in sequence, and then blowing out from the air outlet grille on the top cover plate 233. In this process, the high-temperature and high-pressure refrigerant output by the compressor 240 flows to the condenser 260, and the high-temperature and high-pressure refrigerant is cooled down at the condenser 260 and becomes a low-temperature and high-pressure liquid. After that, the refrigerant is converted into a low-temperature and low-pressure liquid through the throttling device, and flows to the evaporator 270. The low-temperature and low-pressure refrigerant is in the air flow at the evaporator 270 for heat transfer. The refrigerant absorbs the heat of the air flow to condense the air flow, and the liquid water produced by the condensation flows into the water tank 220 for storage. The refrigerant is converted from liquid to low-pressure gas and flows back to the compressor 240, and the condensed air flow is blown into the environment through the air outlet grille on the top cover plate 233 to achieve a dehumidification effect.

[0053] Please refer to Figure 3 , Figure 3 The figure shows an exploded schematic diagram of the dehumidifier electronic control box 100.

[0054] The dehumidifier electric control box 100 provided in this embodiment includes a box body, a PCB bracket 120, a PCB 130, a compressor capacitor 140 and a fan capacitor 150. The box body includes a base 111 and a top cover 112, and the top cover 112 is arranged on the base 111 to enclose an internal space. The PCB bracket 120 is arranged inside the box body, the PCB 130 is arranged inside the box body and connected to the PCB bracket 120, one end of the compressor capacitor 140 extends into the box body and is connected to the PCB bracket 120, and the fan capacitor 150 is arranged inside the box body and connected to the box body.

[0055] Please refer to Figure 4 and Figure 5 , Figure 4 FIG. 1 is a schematic diagram of the structure of the PCB bracket 120 at a first viewing angle. Figure 5 FIG. 1 is a schematic structural diagram of the PCB bracket 120 at a second viewing angle.

[0056] Specifically, a mounting plate 121 is provided on the PCB bracket 120, and the mounting plate 121 is parallel to the bottom plate 1111 of the box body. A first mounting portion 1211, a second mounting portion 1212 and a clearance gap 1213 are respectively provided on the mounting plate 121, and the clearance gap 1213 passes through the mounting plate 121, and the second mounting portion 1212 and the clearance gap 1213 are located at one end of the first mounting portion 1211 in the first direction, and the second mounting portion 1212 and the clearance gap 1213 are arranged sequentially in the second direction, and the first direction and the second direction form an angle and are both parallel to the mounting plate 121.

[0057] PCB130 is installed on the first mounting portion 1211, and PCB130 is parallel to the mounting plate body 121. The compressor capacitor 140 is provided with a fixed end 141, and the fixed end 141 passes through the bottom plate 1111 and extends into the box body to be connected to the second mounting portion 1212. The axis of the compressor capacitor 140 extends in a third direction. The fan capacitor 150 is located in the clearance gap 1213 and is connected to the bottom plate 1111. The third direction forms an angle with the mounting plate body 121.

[0058] It can be understood that the bottom plate 1111 is disposed on the base 111. The first direction is Figure 4 The direction indicated by the X arrow is the second direction. Figure 4 The direction indicated by the Y arrow is the third direction. Figure 4 In fact, in this embodiment, the first direction is perpendicular to the second direction, and the third direction is perpendicular to the mounting plate 121 , that is, the third direction is perpendicular to both the bottom plate 1111 and the PCB 130 .

[0059] Please refer to Figure 6 and Figure 7 , Figure 6 FIG. 1 is a schematic diagram of the structure of the base 111 at a first viewing angle. Figure 7 FIG. 1 is a schematic structural diagram of the base 111 at a second viewing angle.

[0060] The first elastic buckle 1112 and the first side plate 1113 are respectively provided on the opposite sides of the inner wall of the bottom plate 1111 in the second direction, and the first side plate 1113 is penetrated by a first buckle hole 1114; the first matching portion 1214 and the first fixed buckle 1215 are respectively provided on the opposite sides of the mounting plate body 121 in the second direction, the first fixed buckle 1215 is buckled with the first buckle hole 1114, and the first elastic buckle 1112 is buckled with the first matching portion 1214.

[0061] In this embodiment, the number of the first elastic buckle 1112 and the first matching portion 1214 are both two, and the two first elastic buckles 1112 are arranged at intervals in the first direction, and correspondingly, the two first matching portions 1214 are arranged at intervals in the first direction. In addition, the number of the first clamping hole 1114 and the first fixed buckle 1215 is also two, and the two first clamping holes 1114 are arranged at intervals in the first direction, and correspondingly, the two first fixed buckles 1215 are arranged at intervals in the first direction.

[0062] During the process of assembling the PCB bracket 120, firstly, the two first fixing buckles 1215 on the same side of the mounting plate body 121 are buckled into the two first buckle holes 1114 on the first side plate 1113. Then, the side of the mounting plate body 121 provided with the first matching portion 1214 is pressed down. During the pressing process, the first elastic buckle 1112 is affected by the corresponding first matching portion 1214, and undergoes a movement from deformation to restoration, thereby achieving buckling with the first matching portion 1214. In this case, the mounting plate body 121 is fixed on both opposite sides in the second direction, that is, the mounting plate body 121 is assembled on the base 111.

[0063] In order to further improve the stability of the assembly of the PCB bracket 120 on the base 111, in this embodiment, a limit baffle 1115 is also provided on the inner wall of the bottom plate 1111, and the limit baffle 1115 is located on the side where the first elastic buckle 1112 is located. The limit baffle 1115 and the first side plate 1113 are arranged opposite to each other, and the limit baffle 1115 and the first side plate 1113 are used to respectively stop the opposite sides of the mounting plate body 121 in the second direction.

[0064] In addition, a first mounting hole 1116 is provided on the bottom plate 1111 , and a first matching hole 1216 is correspondingly provided on the mounting plate body 121 . The first matching hole 1216 matches with the first mounting hole 1116 via a threaded connector.

[0065] It is understandable that the threaded connector includes screws, bolts, etc. In this embodiment, the threaded connector is a screw. In actual application, when the first fixing buckle 1215 is buckled with the first clamping hole 1114, and the first elastic buckle 1112 is buckled with the first matching portion 1214, the first mounting hole 1116 on the bottom plate 1111 is aligned with the first matching hole 1216 on the mounting plate body 121. The first mounting hole 1116 is a threaded hole. At this time, the screw is passed through the first matching hole 1216 and screwed into the first mounting hole 1116, so that the PCB bracket 120 can be further fixed on the base 111.

[0066] Please refer to Figure 8 and Fig. 9 , Figure 8 Shown Figure 5 A magnified schematic diagram of area A in the middle. Fig. 9 It is a schematic diagram of the connection structure between the second mounting portion 1212 and the compressor capacitor 140 .

[0067] The second mounting portion 1212 is provided with a plug-in barrel 160 with an open end, and the open end of the plug-in barrel 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 into the plug-in barrel 160. Compared with the prior art in which the compressor capacitor 140 is fixed with a cable tie or a clamp, in this embodiment, the assembly of the compressor capacitor 140 is more convenient and quick, saving time and effort.

[0068] In order to ensure that the fixed end 141 of the compressor capacitor 140 can be reliably fixed in the plug-in tube 160, in this embodiment, a limiting ring wall 1411 is protruded on the side wall of the fixed end 141, and a second elastic buckle 161 is provided on the side wall of the plug-in tube 160, and the second elastic buckle 161 is abutted against the side of the end wall of the limiting ring wall 1411 facing away from the fixed end 141.

[0069] It is understandable that before the fixed end 141 of the compressor capacitor 140 is inserted into the plug-in barrel 160, the second elastic buckle 161 protrudes from the side wall of the plug-in barrel 160. In the process of inserting the compressor capacitor 140 into the plug-in barrel 160, the limiting ring wall 1411 first squeezes and pushes the second elastic buckle 161 to deform to withdraw from the plug-in barrel 160. When the limiting ring wall 1411 continues to be inserted to pass over the second elastic buckle 161, the second elastic buckle 161 releases elastic potential energy and realizes abutment against the side of the end wall of the limiting ring wall 1411 away from the fixed end 141, thereby preventing the compressor capacitor 140 from withdrawing from the plug-in barrel 160 and ensuring the reliable fixation of the compressor capacitor 140 in the plug-in barrel 160.

[0070] In order to ensure the effect of abutting and limiting, in this embodiment, the number of the second elastic buckles 161 is two, and the two second elastic buckles 161 are arranged at opposite ends of the same radial direction of the plug-in barrel 160. In other embodiments, according to the actual application conditions, the number of the second elastic buckles 161 can be adjusted to multiple, and the multiple second elastic buckles 161 are evenly distributed in the circumferential direction of the plug-in barrel 160.

[0071] In this embodiment, the second elastic buckle 161 has a supporting end 1611 and a connecting end 1612 that are relatively arranged. The connecting end 1612 is connected to the side wall of the plug-in tube 160. The supporting end 1611 is suspended and supports the limiting ring wall 1411. Compared with the connecting end 1612, the supporting end 1611 is closer to the bottom wall of the plug-in tube 160.

[0072] It is understandable that, in the process of the compressor capacitor 140 being gradually inserted into the plug-in barrel 160, the limiting ring wall 1411 gradually moves from the connecting end 1612 of the second elastic buckle 161 to the abutting end 1611. In this process, the second elastic buckle 161 of the cantilever structure is pushed to deform, so that the abutting end 1611 swings in the direction away from the axis of the plug-in barrel 160. When the limiting ring wall 1411 continues to be inserted beyond the abutting end 1611, the second elastic buckle 161 releases elastic potential energy, driving the abutting end 1611 to move and reset in the direction close to the axis of the plug-in barrel 160. After the abutting end 1611 is reset, it abuts against the limiting ring wall 1411.

[0073] In order to facilitate the deformation of the second elastic buckle 161, in the present embodiment, a first avoidance hole 1613 is penetrated through the side wall of the plug-in tube 160, and the connecting end 1612 is connected to the side hole wall of the first avoidance hole 1613 close to the opening of the plug-in tube 160. The second elastic buckle 161 is used to drive the supporting end 1611 to rotate from the first avoidance hole 1613 toward the direction away from the axis of the plug-in tube 160 under the push of the limiting ring wall 1411.

[0074] In fact, the second elastic buckle 161 is integrally formed with the plug-in tube 160 . The second elastic buckle 161 can be formed by punching a solid area on the side wall of the plug-in tube 160 corresponding to the first avoidance hole 1613 , and the first avoidance hole 1613 is formed at the same time as the second elastic buckle 161 is formed.

[0075] A guide sliding surface 1614 and a fitting surface 1615 are respectively provided on one side of the second elastic buckle 161 close to the axis of the plug-in tube 160. The guide sliding surface 1614 and the fitting surface 1615 are arranged in sequence from the connecting end 1612 to the supporting end 1611. One side of the guide sliding surface 1614 is connected to one side of the fitting surface 1615 at an angle and the transition is smooth. The fitting surface 1615 fits with the side wall of the compressor capacitor 140.

[0076] The connecting corner of the guide sliding surface 1614 and the fitting surface 1615 extends into the interior of the plug-in tube 160. In the process of gradually inserting the compressor capacitor 140 into the plug-in tube 160, the limiting ring wall 1411 of the compressor capacitor 140 first slides toward the corner along the guide sliding surface 1614, and in this process, the second elastic buckle 161 is pushed to deflect. The guide sliding surface 1614 guides the insertion process of the compressor capacitor 140 to ensure a smooth insertion process. In the process of the limiting ring wall 1411 crossing the corner and sliding on the fitting surface 1615, the second elastic buckle 161 no longer deflects, and there is a gap between the fitting surface 1615 and the outer side wall of the compressor capacitor 140. Until the limiting ring wall 1411 slides out of the fitting surface 1615, the second elastic buckle 161 deflects and resets to the fitting surface 1615 and the side wall of the compressor capacitor 140, and the abutting end 1611 abuts against the limiting ring wall 1411.

[0077] In order to facilitate the connection of the compressor capacitor 140, in this embodiment, a wiring piece is protruding from the end wall of the fixed end 141, and a first clearance hole is opened on the bottom wall of the plug-in barrel 160, and the wiring piece passes through the first clearance hole. In fact, the PCB 130 is arranged on the side of the mounting plate body 121 opposite to the opening direction of the plug-in barrel 160, that is, the wiring piece protruding from the end wall of the fixed end 141 passes through the first clearance hole to reach the same side of the PCB 130, which is convenient for subsequent wiring of the subsequent wiring piece.

[0078] In this embodiment, the compressor capacitor 140 is cylindrical, and correspondingly, the plug-in barrel 160 encloses a cylindrical cavity with one end open. In order to prevent the compressor capacitor 140 from rolling inside the plug-in barrel 160, in this embodiment, a plurality of stop ribs are provided on the inner side wall of the plug-in barrel 160, and the plurality of stop ribs are radially abutted against the outer side wall of the compressor capacitor 140.

[0079] Please refer to Fig.10 and Fig.11 , Fig.10 Shown Figure 4 The enlarged schematic diagram of area B in the middle. Fig.11 Shown Figure 5 Enlarged schematic diagram of area C in the middle.

[0080] A plurality of folded edges are vertically arranged on one side of the mounting plate body 121, and the plurality of folded edges and the mounting plate body 121 together form a mounting cavity, and the PCB130 is accommodated in the mounting cavity; the plurality of folded edges include a first folded edge 170 and a second folded edge 180 which are arranged opposite to each other in the second direction, a third elastic buckle 171 is arranged on the first folded edge 170, and a second fixed buckle 181 is arranged on the second folded edge 180, and the second fixed buckle 181 extends 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 the opposite sides of the PCB130 away from the side of the mounting plate body 121.

[0081] During the process of assembling PCB130, firstly, one side of PCB130 is embedded in the side of the second fixing buckle 181 provided on the second folded edge 180 close to the mounting plate body 121, and then the PCB130 is gradually flattened. During this process, the side of PCB130 away from the second fixing buckle 181 gradually squeezes and pushes the third elastic buckle 171 to deflect in the direction away from the second folded edge 180, and the third elastic buckle 171 accumulates elastic potential energy during this process. When the side of PCB130 away from the second fixing buckle 181 passes over the third elastic buckle 171, the third elastic buckle 171 releases the elastic potential energy and resets, and the third elastic buckle 171 re-extends into the mounting cavity and stops the side of PCB130 away from the second fixing buckle 181, and the assembly of PCB130 on the PCB bracket 120 is completed.

[0082] In this embodiment, the number of the third elastic buckle 171 and the second fixed buckle 181 are both two, and the two third elastic buckles 171 are arranged at intervals along the first direction on the first folded edge 170, and the two second fixed buckles 181 are arranged at intervals along the second direction on the second folded edge 180 to ensure reliable fixation of the PCB 130. In other embodiments, the number of the third elastic buckle 171 and the second fixed buckle 181 can be adjusted to multiple according to actual application conditions.

[0083] In fact, the first folded edge 170 and the second folded edge 180 realize the stop limit on the two opposite sides of the PCB 130 in the second direction, and the third elastic buckle 171, the second fixed buckle 181 and the mounting plate body 121 realize the stop limit on the two opposite sides of the PCB 130 in the third direction. In order to ensure the limit of the PCB 130 in the first direction, in this embodiment, the plurality of folded edges also include a third folded edge and a fourth folded edge, and the third folded edge and the fourth folded edge realize the stop limit on the two opposite sides of the PCB 130 in the first direction. The first folded edge 170, the second folded edge 180, the third folded edge, the fourth folded edge and the mounting plate body 121 together form a mounting cavity.

[0084] The third elastic clip 171 extends along the depth direction of the installation cavity. The third elastic clip 171 has a movable end and a fixed end 141 that are relatively arranged. The fixed end 141 is connected to the first folded edge 170. Compared with the fixed end 141, the movable end is closer to the installation plate body 121. The movable end is suspended and stops the PCB130.

[0085] It is understandable that after one side of the PCB 130 is embedded under the second fixed buckle 181, in the process of gradually flattening the PCB 130, the side of the PCB 130 away from the second fixed buckle 181 gradually moves from the fixed end 141 of the third elastic buckle 171 to the movable end. In this process, the third elastic buckle 171 gradually deforms, so that the movable end swings in the direction away from the second folded edge 180. When the side of the PCB 130 away from the second fixed buckle 181 passes over the movable end, the third elastic buckle 171 releases elastic potential energy, driving the movable end to move in the direction close to the second folded edge 180 to the top of the PCB 130, thereby stopping the side of the PCB 130 away from the mounting plate 121.

[0086] In order to ensure that the third elastic buckle 171 can swing smoothly during this process, a second avoidance hole 1711 is penetrated through the first folded edge 170, and the fixed end 141 is connected to the hole wall on the side of the second avoidance hole 1711 away from the mounting plate body 121. The third elastic buckle 171 is used to drive the movable end to exit the mounting cavity through the second avoidance hole 1711 when the PCB130 is inserted into the mounting cavity.

[0087] In fact, the third elastic buckle 171 is integrally formed with the first folded edge 170 , and the third elastic buckle 171 can be formed by punching the first folded edge 170 , so that the second avoidance hole 1711 is formed at the same time as the third elastic buckle 171 is formed.

[0088] In order to ensure that PCB130 can smoothly pass through the third elastic clip 171 and be embedded in the installation cavity, in this embodiment, a guide sliding slope 1712 is provided on the side of the third elastic clip 171 close to the second folded edge 180, and from the fixed end 141 to the movable end, the guide sliding slope 1712 gradually approaches the second folded edge 180.

[0089] In the process of gradually flattening PCB130, the side of PCB130 away from the second fixing buckle 181 slides on the guide sliding slope 1712. In this process, the third elastic buckle 171 is subjected to a force in the direction away from the second folded edge 180, so that the third elastic buckle 171 rotates from the second avoidance hole 1711 to gradually withdraw from the installation cavity. When PCB130 slides out of the guide sliding slope 1712, the third elastic buckle 171 is reset and realizes the stop limit on the side of PCB130 away from the installation plate.

[0090] In order to improve the structural strength of the third elastic buckle 171, in this embodiment, a U-shaped reinforcement rib is erected on one side of the third elastic buckle 171 close to the second folded edge 180, and the guide sliding slope 1712 is arranged on the side of the reinforcement rib close to the second folded edge 180.

[0091] In addition, in order to ensure that the PCB 130 is assembled firmly and prevent the PCB 130 from shaking in the installation cavity and causing the components on the PCB 130 to loosen, in this embodiment, a support portion is protruded on one side of the installation board 121 corresponding to the multiple folded edges, and the support portion abuts against the side of the PCB 130 close to the installation board 121, and the third elastic buckle 171 and the second fixed buckle 181 both abut against the side of the PCB 130 away from the installation board 121. In other words, when the PCB 130 is assembled, the PCB 130 is clamped and fixed by the support portion, the third elastic buckle 171 and the second fixed buckle 181.

[0092] In this embodiment, the fan capacitor 150 is connected and fixed to the bottom plate 1111 by a threaded connector. Specifically, a second mounting hole 1117 is provided in the area corresponding to the clearance notch 1213 on the bottom plate 1111, and a second matching hole 151 is correspondingly provided on the fan capacitor 150. The second matching hole 151 matches the second mounting hole 1117 through a threaded connector. Similarly, the threaded connector is a screw, which passes through the second matching hole 151 and is screwed into the second mounting hole 1117 to complete the fixing of the fan capacitor 150 on the bottom plate 1111.

[0093] Please refer to Fig.12 , Fig.12 It is a partial structural schematic diagram of the middle partition 210.

[0094] For the installation and fixation of the dehumidifier 200 capacitor on the middle partition 210, the middle partition 210 is provided with a mounting wall 211 and a mounting recess 212 which is recessed relative to the mounting wall 211 and away from the box body. The bottom plate 1111 is connected to the mounting wall 211 through a threaded connector, and one end of the compressor capacitor 140 away from the fixed end 141 is embedded in the mounting recess 212.

[0095] In order to facilitate the fixation of the bottom plate 1111 and the mounting wall 211 through threaded connectors, in this embodiment, a third fixing buckle 213 is also provided on the middle partition plate 210, a positioning plate 1118 is provided on the outer wall of the bottom plate 1111, a second clip hole is penetrated through the positioning plate 1118, and the third fixing buckle 213 is engaged with the third clip hole.

[0096] It can be understood that the engagement of the third fixing buckle 213 and the third buckle hole provides positioning and pre-support for the subsequent screw fixing of the base plate 1111 and the mounting wall 211, thereby improving the assembly efficiency of the dehumidifier 200 capacitor on the middle partition 210 and reducing the difficulty of assembly.

[0097] In summary, the dehumidifier electronic control box 100 provided in this embodiment has the characteristics of compact internal structure and smaller size. In addition, since the water tank 220, the middle partition plate 210 and the box body are arranged in sequence in a direction perpendicular to the bottom plate 1111, when the size of the housing 230 is fixed, the dehumidifier electronic control box 100 occupies less space in the third direction, so that the water tank 220 can be larger in size and the water storage capacity can be increased.

[0098] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
