[0052] The present invention provides a dehumidifier.

[0053] In the embodiments of the present invention, please refer to Figures 1 to 3 , this dehumidifier includes a middle partition 30, a water tank 10, a mounting bracket 20, a liquid level detection device 40 and a water pump assembly. The water tank 10 is disposed on one side of the middle partition 30. A fixing structure 22 is provided on the outer surface of the mounting bracket 20. The liquid level detection device 40 is disposed on the mounting bracket 20. The water pump assembly includes a water suction pipe 51. The water suction pipe 51 is installed on the fixing structure 22, and the water inlet end of the water suction pipe 51 is located at the bottom of the water tank 10.

[0054] In this embodiment, the mounting bracket 20 is installed inside the water tank 10, and the water pump assembly is used to drain the water in the water tank 10 to the outside of the dehumidifier. Specifically, the water pump assembly further includes a water pump 52 and a drain pipe 56. The water inlet end of the water pump 52 is communicated with a suction pipe 51, and the water outlet end of the water pump 52 is communicated with the drain pipe 56. The drain pipe 56 is used to drain the water to the outside of the dehumidifier. The dehumidifier further includes a controller. The liquid level detection device 40 and the water pump assembly are both electrically connected to the controller, so that when the liquid level detection device 40 detects that the water in the water tank 10 reaches a preset water level, a water level signal can be transmitted to the controller, and then the controller controls the water pump assembly to pump water to drain the water in the water tank 10. Of course, in other embodiments, the liquid level detection device 40 can also be electrically connected to an alarm to remind the user through the alarm, and the user manually starts the water pump assembly to pump water.

[0055] Among them, the preset water level can be located at the high water level of the water tank 10, that is, the preset water level is located at the upper end of the water tank 10. When the water in the water tank 10 reaches the preset water level, it means that the water tank 10 is about to be full. At this time, the water in the water tank 10 can be drained by starting the water pump assembly. The preset water level can be located at the low water level of the water tank 10, that is, the preset water level is located at the bottom of the water tank 10. When the water in the water tank 10 reaches the preset water level, the water in the water tank 10 at least covers the water inlet 202 of the suction pipe 51. At this time, the water in the water tank 10 can be drained by starting the water pump assembly, avoiding the situation of starting the water pump assembly when there is no water or too much water in the water tank 10.

[0056] The technical solution of the present invention is to set a mounting bracket 20, a liquid level detection device 40 and a water pump assembly on the dehumidifier, and install the liquid level detection device 40 and the suction pipe 51 of the water pump assembly on the mounting bracket 20, so that the water inlet end of the suction pipe 51 is located at the bottom of the water tank 10. In this way, the water level in the water tank 10 can be detected by the liquid level detection device 40, and then the water pump assembly can be started or stopped according to the water level situation in the water tank 10, and the water in the water tank 10 can be automatically drained by the water pump assembly. This can greatly facilitate the drainage of the water tank 10 and avoid the situation that the user needs to pour water frequently during the dehumidification process, reducing the number of times the user pours water. Compared with the method of each having a mounting frame for the suction pipe 51 and the liquid level detection device 40, in this solution, the liquid level detection device 40 and the suction pipe 51 of the water pump assembly are both installed on the mounting bracket 20, which can reduce the number of parts of the dehumidifier and improve the structural compactness of the dehumidifier. Moreover, the water pump assembly can be started after it is determined by the liquid level detection device 40 that there is water in the water tank 10, which can prevent the situation of starting the water pump assembly when there is no water or too much water in the water tank 10, and is beneficial to extending the service life of the water pump assembly.

[0057] Please refer to Figures 4 to 9, in one embodiment, the mounting bracket 20 is provided with a receiving cavity 201 and a water inlet 202 communicating with the receiving cavity 201. The water inlet 202 is located at the bottom of the mounting bracket 20. The liquid level detection device 40 includes a floating part 41, a triggering part 42 and a detection switch 43. The floating part 41 is movably mounted in the receiving cavity 201. The triggering part 42 is connected to the floating part 41. The detection switch 43 is spaced above the triggering part 42. When the floating part 41 floats upward under the action of water, the triggering part 42 triggers the detection switch 43. Specifically, the water inlet 202 is provided on the bottom surface of the mounting bracket 20. Optionally, the water inlet 202 is provided with an open mouth 412 to simplify the structure of the mounting bracket 20. Under the action of gravity, the floating part 41 can at least move down to the water inlet 202 to ensure that the water can contact the floating part 41 when entering from the water inlet 202. The detection switch 43 can be mounted on the mounting bracket 20 or on the middle partition 30 of the dehumidifier, as long as the detection switch 43 is spaced above the triggering part 42 and the triggering part 42 can trigger the detection switch 43 when the floating part 41 floats upward under the action of water. Of course, the water inlet 202 can also be provided on the side surface of the mounting bracket 20 and near the bottom position.

[0058] When the liquid level detection device 40 is used on a dehumidifier, the mounting bracket 20 can be placed at the bottom of the water tank 10, so that the floating part 41 is located at the bottom of the water tank 10. In this way, after the dehumidifier starts to work, the water in the water tank 10 gradually increases. Until the buoyancy generated by the water on the floating part 41 is greater than the gravity of the floating part 41 and the triggering part 42, the floating part 41 can drive the triggering part 42 to move upward, so that the detection switch 43 can be triggered by the triggering part 42. At this time, it can be determined that there is water in the water tank 10. When there is a water pump assembly for draining the water tank 10 in the dehumidifier, the water pump 52 can be started to drain water, avoiding the situation of starting the water pump 52 when there is no water in the water tank 10. In addition, the mounting bracket 20 can also be placed at a position near the top of the water tank 10, so that the floating part 41 is located at a position near the top of the water tank 10. When the water in the water tank 10 is almost full, an alarm can be given by the triggering part 42 triggering the detection switch 43.

[0059] In one embodiment, the floating part 41 and the triggering part 42 are integrally formed, so as to reduce the assembly process of the floating part 41 and the triggering part 42, which is beneficial to improving the assembly efficiency and can ensure the reliable connection between the floating part 41 and the triggering part 42. Of course, in other embodiments, the floating part 41 and the triggering part 42 are detachably connected.

[0060] In one embodiment, the floating part 41 is provided with a floating cavity 411 and an opening 412 communicating with the floating cavity 411, and the opening 412 is arranged at the bottom of the floating part 41. Specifically, the opening 412 is arranged on the bottom surface of the floating part 41, that is, the opening 412 faces downward. After the liquid level detection device 40 is installed in the water tank 10 of the dehumidifier, when the water in the water tank 10 reaches the opening 412, the water can seal the opening 412, so that the floating cavity 411 forms a complete sealed cavity. At this time, the floating cavity 411 is filled with gas. When the water surface rises to make the buoyancy greater than the gravity, the floating part 41 will float. Thus, when the opening 412 is arranged at the bottom of the floating part 41, it is convenient to form the floating cavity 411. Moreover, there is no need to additionally provide a cover plate at the opening 412, which can reduce the number of parts and the assembly process of the floating part 41, and can also reduce the overall weight of the floating part 41, which is beneficial to improving the floating speed of the floating part 41. Of course, in other embodiments, the floating cavity 411 can also be a sealed cavity; or the floating part 41 is made of a foaming material.

[0061] In one embodiment, the floating part 41 is provided with a plurality of floating cavities 411, and the floating part 41 is provided with an opening 412 corresponding to each floating cavity 411. Specifically, the number of the floating cavities 411 is at least two, and adjacent two floating cavities 411 are separated by a partition board, and the openings 412 of the respective floating cavities 411 are located on the same horizontal plane. By providing a plurality of floating cavities 411, the buoyancy of the floating part 41 can be increased. Moreover, compared with the case of providing a large cavity, separating the plurality of floating cavities can make the structural strength of the floating part 41 higher, reduce the possibility of deformation of the floating part, and ensure the structural reliability of the floating part 41. Of course, in other embodiments, the floating part 41 can also be provided with only one floating cavity 411.

[0062] In one embodiment, one of the cavity walls of the accommodating cavity 201 and the floating part 41 is provided with a sliding rib 413 that slidably abuts against the other, and the sliding rib 413 extends in the up and down direction. Specifically, the sliding rib 413 can be arranged on the cavity wall of the accommodating cavity 201, and the sliding rib 413 is in sliding contact with the outer side surface of the floating part 41. The sliding rib 413 can also be arranged on the outer side surface of the floating part 41, and the sliding rib 413 is in sliding contact with the cavity wall of the accommodating cavity 201. In this way, the contact area between the cavity wall of the accommodating cavity 201 and the floating part 41 can be reduced, that is, the friction between the cavity wall of the accommodating cavity 201 and the floating part 41 can be reduced, and the resistance when the floating part 41 moves upward in the accommodating cavity 201 can be reduced, so that the floating part 41 is more likely to move upward in the accommodating cavity 201, and the floating speed of the floating part 41 is improved. Of course, in other embodiments, the sliding rib 413 can also not be provided.

[0063] In one embodiment, the number of the sliding ribs 413 is multiple, and the multiple sliding ribs 413 are distributed at intervals in the circumferential direction of the floating portion 41. Specifically, the sliding ribs 413 are provided around the floating portion 41, so that the floating portion 41 can be in sliding contact through the sliding ribs 413 at various positions in the circumferential direction, and the situation that the outer side surface of the floating portion 41 contacts the wall surface of the accommodating cavity 201 can be avoided.

[0064] In one embodiment, the mounting bracket 20 is further provided with a positioning hole 204 communicating with the accommodating cavity 201. The triggering portion 42 includes a connecting rod portion 421 and a triggering member 424. The connecting rod portion 421 is connected to the floating portion 41, the triggering member 424 is arranged at the upper end of the connecting rod portion 421, and the connecting rod portion 421 is slidably mounted in the positioning hole 204. Specifically, the triggering member 424 is used to trigger the detection switch 43. The positioning hole 204 extends in the up and down direction, and the connecting rod portion 421 can slide in the positioning hole 204 in the up and down direction. With such a setting, the connecting rod portion 421 can be positioned and installed through the positioning hole 204, and the deviation of the connecting rod portion 421 during the up and down movement can be restricted through the positioning hole 204, ensuring the movement stability of the connecting rod portion 421. Of course, in other embodiments, a guiding column extending in the up and down direction can also be provided on the mounting bracket 20, and the connecting rod portion 421 is provided with a guiding hole slidably matched with the guiding column.

[0065] In one embodiment, the triggering member 424 is a magnet, and the detection switch 43 is a magnetic control switch; or, the triggering member 424 is a light blocking member or a light reflecting member, and the detection switch 43 is a laser sensor; or, the triggering member 424 is a triggering head, and the detection switch 43 is a tactile switch. Specifically, when the triggering member 424 is a triggering head and the detection switch 43 is a tactile switch, the triggering member 424 can trigger the detection switch 43 by directly touching the detection switch 43. When the triggering member 424 is a magnet and the detection switch 43 is a magnetic control switch, only when the triggering member 424 moves up to a preset position with the floating portion 41, the detection switch 43 can be triggered. In this way, it is not necessary for the triggering member 424 to contact the detection switch 43, so that the detection switch 43 can be hermetically arranged, reducing the risk of water ingress into the detection switch 43. When the triggering member 424 is a light blocking member or a light reflecting member and the detection switch 43 is a laser sensor, similarly, only when the triggering member 424 moves up to a preset position with the floating portion 41, the detection switch 43 can be triggered. In this way, it is not necessary for the triggering member 424 to contact the detection switch 43, so that the detection switch 43 can be hermetically arranged, reducing the risk of water ingress into the detection switch 43.

[0066] In one embodiment, the connecting rod portion 421 includes a positioning post 422 and a plurality of connecting plates 423. Each connecting plate 423 has a connecting side edge extending in the up and down direction. The connecting side edges of the connecting plates 423 are connected to each other. Each connecting plate 423 is connected to the floating portion 41. The positioning post 422 is connected to the connection part at the upper ends of the connecting plates 423. The positioning post 422 is slidably installed in the positioning hole 204. Specifically, the number of the connecting plates 423 is at least two, and an included angle is provided between two adjacent connecting plates 423, that is, a gap is provided between the positions of two adjacent connecting plates 423. Compared with the structure that the connecting rod portion 421 is a solid column, in this way, while ensuring that the connecting rod portion 421 has sufficient structural strength, the weight of the connecting rod portion 421 can be reduced, so that the floating portion 41 is more likely to move upward, and the floating speed of the floating portion 41 is increased. In one embodiment, the floating portion 41 and the connecting rod portion 421 are integrally formed.

[0067] Please refer to Figures 8 to 11 , in one embodiment, a limiting hole 203 is provided on the cavity wall of the accommodating cavity 201, and a limiting protrusion 414 is provided on the side surface of the floating portion 41. The limiting protrusion 414 extends into the limiting hole 203 to limit the floating portion 41 from moving out of the accommodating cavity 201. Specifically, the size of the limiting protrusion 414 is smaller than the size of the limiting hole 203. When the floating portion 41 is in a waterless environment, under the action of gravity, the limiting protrusion 414 abuts against the lower edge of the limiting hole 203, and the upper edge of the limiting protrusion 414 is spaced from the upper edge of the limiting hole 203. When the floating portion 41 floats upward under the action of water, the limiting protrusion 414 can move upward in the limiting hole 203. By providing the limiting protrusion 414 on the side surface of the floating portion 41, when the limiting protrusion 414 extends into the limiting hole 203 on the cavity wall of the accommodating cavity 201, the floating portion 41 can be prevented from coming out of the accommodating cavity 201, and the floating portion 41, the triggering portion 42 and the mounting bracket 20 can be assembled into a whole assembly, which is convenient for installation in the water tank 10 of the dehumidifier. Of course, in other embodiments, a limiting edge can also be provided at the water inlet 202 to limit the floating portion 41 from moving out of the accommodating cavity 201.

[0068] Please refer to Figure 10 and Figure 11, in one embodiment, the fixing structure 22 includes a connecting portion 221 and a shielding portion 222. The connecting portion 221 is connected to the outer surface of the mounting bracket 20. The shielding portion 222 is connected to the connecting portion 221 and is spaced from the outer surface of the mounting bracket 20. The water extraction pipe 51 is clamped between the shielding portion 222 and the outer surface of the mounting bracket 20. Specifically, the fixing structure 22 further includes a limiting rib 224. The limiting rib 224 is provided on the side of the shielding portion 222 facing the outer surface of the mounting bracket 20. The limiting rib 224 is spaced from the connecting portion 221. The water extraction pipe 51 is located between the connecting portion 221 and the limiting rib 224, that is, the limiting rib 224 can limit the water extraction pipe 51 from moving away from the connecting portion 221, ensuring that the water extraction pipe 51 is stably fixed on the mounting bracket 20. The fixing structure 22 is integrally formed on the mounting bracket 20, that is, the connecting portion 221, the shielding portion 222 and the limiting rib 224 are integrally formed. Compared with the method of fixing the water extraction pipe 51 on the mounting bracket 20 by a clamp or a screw, this can reduce the number of components, thereby reducing the installation process and improving the installation efficiency. Of course, in other embodiments, the distance between the shielding portion 222 and the outer surface of the mounting bracket 20 can also be made smaller than the outer diameter of the water extraction pipe 51, so that the water extraction pipe 51 is clamped between the shielding portion 222 and the outer surface of the mounting bracket 20.

[0069] In one embodiment, the mounting bracket 20 includes a first mounting section 205 and a second mounting section 206 connected to the upper end of the first mounting section 205. The water inlet 202 is provided at the bottom of the first mounting section 205. The interiors of the first mounting section 205 and the second mounting section 206 together form a receiving cavity 201. The floating portion 41 is located in the first mounting section 205. The triggering portion 42 (connecting rod portion 421) is provided in the second mounting section 206. The circumferential dimension of the second mounting section 206 is smaller than the circumferential dimension of the first mounting portion. To ensure that the floating portion 41 can have a greater buoyancy while reducing the weight of the triggering portion 42 (connecting rod portion 421), the floating portion 41 can be set to be larger, while the size of the triggering portion 42 (connecting rod portion 421) is set to be smaller. And making the circumferential dimension of the second mounting section 206 smaller than the circumferential dimension of the first mounting portion can make the gap between the second mounting section 206 and the triggering portion 42 (connecting rod portion 421) smaller, which is beneficial to reducing the overall size of the mounting bracket 20 and improving the structural compactness of the dehumidification device. Moreover, when the mounting bracket 20 is installed in the water tank 10, the space occupied by the mounting bracket 20 in the water tank 10 can be reduced, so that the water tank 10 can hold more water.

[0070] In one embodiment, the shielding portion 222 is provided on the second mounting section 206 and extends in the up and down direction. A transition section 223 is provided at the lower end of the shielding portion 222. The transition section 223 is located at the connection between the first mounting section 205 and the second mounting section 206. The water extraction pipe 51 is located between the transition section 223 and the surface of the mounting bracket 20. In this way, the part of the water extraction pipe 51 located at the connection between the first mounting section 205 and the second mounting section 206 can be constrained by the transition section 223, so that the water extraction pipe 51 can better fit on the surface of the mounting bracket 20, making the structure of the components more compact after the mounting bracket 20 and the water extraction pipe 51 are assembled. Optionally, the transition section 223 is in a convex arc shape protruding towards the connection between the first mounting section 205 and the second mounting section 206, which is beneficial for the smooth transition of the part of the water extraction pipe 51 located at the connection between the first mounting section 205 and the second mounting section 206.

[0071] In one embodiment, the dehumidifier further includes a filter bracket 23. The filter bracket 23 is provided with a filter cavity and a water filter joint 231 communicating with the filter cavity. The lower end of the water extraction pipe 51 is connected to the water filter joint 231. In this embodiment, the filter bracket 23 is connected to the bottom of the mounting bracket 20. The filter bracket 23 is provided with a downward mounting opening. The dehumidifier further includes a filter net and a filter cover 24. The filter net is arranged in the filter cavity, and the filter cover 24 covers the mounting opening to limit the filter net in the filter cavity. The filter cover 24 is provided with a water filter inlet 241 communicating with the filter cavity. In this way, dust particles and other impurities in the water in the water tank 10 can be filtered, reducing the situation that impurities enter the drainage pump assembly and cause the drainage pump assembly to be blocked. Moreover, by connecting the filter bracket 23 to the mounting bracket 20, the filter bracket 23 can be fixed firmly, avoiding the situation that the filter bracket 23 and the water extraction pipe 51 shake. Of course, in other embodiments, the filter net can also be clamped on the cavity wall of the filter cavity, so that the filter cover 24 can be omitted. Additionally, in other embodiments, the filter bracket 23 is separately provided from the mounting bracket 20.

[0072] In one embodiment, the fixing structure 22 and the mounting bracket 20 are integrally formed. Specifically, the connecting portion 221, the shielding portion 222, the limiting rib 224, the transition section 223, and the filter bracket 23 are integrally formed on the mounting bracket 20. In this way, it is convenient for molding, the assembly process between the fixing structure 22 and the mounting bracket 20 can be reduced, the assembly efficiency can be improved, and the connection reliability between the fixing structure 22 and the mounting bracket 20 can also be ensured. Of course, in other embodiments, the fixing structure 22 can also be snap-connected or connected to the mounting bracket 20 by screws.

[0073] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 12 and Figure 13, in one embodiment, the water pump assembly further includes a first connector 53 and a second connector 54. The second connector 54 is disposed on the middle partition 30, and the first connector 53 is disposed on the mounting bracket 20. One end of the first connector 53 is connected to the water suction pipe 51, and the other end is inserted into the first connector 53. When the first connector 53 is inserted into the second connector 54, the first connector 53 and the second connector 54 can be communicated, that is, the water flowing from the water suction pipe 51 to the first connector 53 can flow to the second connector 54 and be discharged from the second connector 54. By inserting and mating the first connector 53 and the second connector 54, it is convenient to connect the first connector 53 and the second connector 54 during the process of disassembling and assembling the water tank 10. Moreover, by directly disposing the second connector 54 on the middle partition 30 without additionally providing a mounting seat, the mounting seat is omitted, thereby reducing the cost of the dehumidifier and improving the assembly efficiency of the dehumidifier. Among them, the first connector 53 can be inserted into the second connector 54, or the second connector 54 can be inserted into the first connector 53.

[0074] In one embodiment, the dehumidifier further includes a housing. The middle partition 30 is disposed inside the housing.

That is, the end of the second connector 54 inserted into the first connector 53 is disposed facing the water tank assembly port. In this way, the direction in which the water tank 10 is pushed into the housing is consistent with the insertion direction of the first connector 53 and the second connector 54. Thus, during the process of pushing the water tank 10 into the housing from the water tank assembly port, the first connector 53 and the second connector 54 can be gradually inserted. When the water tank 10 is installed in place, the first connector 53 and the second connector 54 are also inserted in place. In this way, it is not necessary to manually connect the first connector 53 and the second connector 54 additionally, which is convenient for disassembling and assembling the water tank 10. Of course, in other embodiments, the second connector 54 can also extend downward, the first connector 53 can extend upward, and the water tank 10 can move upward after being pushed into the housing so that the first connector 53 and the second connector 54 are inserted.

[0075] Please refer to Figure 12 and Figure 13 , in one embodiment, a seal 60 is provided between the first connector 53 and the second connector 54.

Among them, the seal 60 can be, but is not limited to, a sealing ring.

[0076] In one embodiment, the second joint 54 is sleeved outside the first joint 53. A sealing groove 541 is provided on the inner side of the second joint 54 or the outer side of the first joint 53. The seal 60 is limited in the sealing groove 541, and a part of the seal 60 protrudes outside the sealing groove 541. That is, the first joint 53 is inserted into the second joint 54. In this embodiment, the sealing groove 541 is provided on the inner side of the second joint 54. The sealing groove 541 is annular and is disposed around the outer periphery of the first joint 53. The seal 60 is an O-ring. When the seal 60 is installed in the sealing groove 541, a part of the seal 60 protrudes from the inner side surface of the second joint 54. When the first joint 53 is inserted into the second joint 54, the seal 60 can be sleeved around the outer periphery of the first joint 53 to seal the gap between the first joint 53 and the second joint 54. In this way, the seal 60 can be limited by the sealing groove 541, reducing the risk of the seal 60 falling off during the insertion and extraction of the first joint 53 and the second joint 54.

[0077] Optionally, in one embodiment, a retaining member 70 is provided on the inner side of the second joint 54. The retaining member 70 is disposed such that the seal 60 is limited between the retaining member 70 and the sealing groove 541. In this way, the seal 60 can be prevented from coming out of the second joint 54, further reducing the risk of the seal 60 falling off during the insertion and extraction of the first joint 53 and the second joint 54.

[0078] In another embodiment, the first joint 53 is sleeved outside the second joint 54. A sealing groove 541 is provided on the inner side of the first joint 53 or the outer side of the second joint 54. The seal 60 is limited in the sealing groove 541, and a part of the seal 60 protrudes outside the sealing groove 541. In this way, the seal 60 can also be limited by the sealing groove 541, reducing the risk of the seal 60 falling off during the insertion and extraction of the first joint 53 and the second joint 54.

[0079] Please refer to Figure 3 、 Figure 12 、 Figure 13 and Figure 14, in one embodiment, the middle partition plate 30 includes a support plate 31 and a mounting plate 33 connected to the upper end of the support plate 31.

The mounting plate 33 is provided with a mounting opening 331, and the second joint 54 is installed at the mounting opening 331. Specifically, the water pump assembly further includes a first connecting pipe 57. The first connecting pipe 57 passes through the mounting opening 331 and is connected to the second joint 54. That is, one end of the second joint 54 is inserted into the first joint 53, and the other end is connected to the first connecting pipe 57. In this way, when the mounting opening 331 is provided on the mounting plate 33, the first connecting pipe 57 for connecting the second joint 54 of the water pump assembly can pass through, avoiding the situation of connecting the first connecting pipe 57 around the edge of the mounting plate 33 to the second joint 54, which can reduce the length of the first connecting pipe 57, thereby reducing the occupied space of the first connecting pipe 57 in the dehumidifier and making the internal structure of the dehumidifier more compact. Of course, in other embodiments, the second joint 54 can also be installed on the support plate 31.

[0080] Please refer to Figure 3 , Figures 12 to 15 , in one embodiment, the middle partition plate 30 further includes a fixing bracket 34. The fixing bracket 34 is installed at the mounting opening 331, and the second joint 54 is installed on the fixing bracket 34. That is, the second joint 54 can be installed on the fixing bracket 34 first, and then the fixing bracket 34 can be installed at the mounting opening 331. In this way, when the second joint 54 is installed on the fixing bracket 34 first, the connection reliability between the second joint 54 and the fixing bracket 34 can be better ensured, and the connection area between the fixing bracket 34 and the mounting plate 33 can be larger, and there are more connection positions, which can better ensure the connection reliability between the fixing bracket 34 and the mounting plate 33, that is, the installation stability of the second joint 54 is improved, thereby reducing the risk of loosening or even falling of the second joint 54 during the insertion and extraction process between the first joint 53 and the second joint 54. Moreover, during the insertion and extraction process between the first joint 53 and the second joint 54, the force distribution between the fixing bracket 34 and the mounting plate 33 is wider and more uniform, reducing the risk of the mounting plate 33 cracking due to concentrated force between the fixing bracket 34 and the mounting plate 33. Of course, in other embodiments, the second joint 54 can also be directly fixed on the mounting plate 33.

[0081] In one embodiment, the fixing bracket 34 is provided with a buckle 341 extending upward. The buckle 341 is clamped on the edge of the mounting opening 331. In this way, screw fixing is not required, which is convenient for disassembly and assembly and is beneficial to improving the assembly efficiency.

In this way, using the mounting plate 33 to install the water pump 52 can improve the space utilization rate on the mounting plate 33 and further improve the structural compactness of the dehumidifier. Moreover, when the water pump 52 is installed on the mounting plate 33, the length of the first connecting pipe 57 can be reduced. Of course, in other embodiments, the water pump 52 can also be installed on the support plate 31 or on the chassis of the dehumidifier.

[0083] In one embodiment, a fixed bayonet 332 is provided on the upper surface of the mounting plate 33, and the fixed bayonet 332 is arranged adjacent to the edge of the mounting opening 331. The first connecting pipe 57 is clamped in the fixed bayonet 332. In this way, the first connecting pipe 57 can be better attached to the upper surface of the mounting plate 33, which is beneficial to improving the structural compactness on the upper side of the mounting plate 33.

[0084] Please refer to Figure 3 and Figure 16 , in one embodiment, the water pump assembly further includes a drain joint 55 and a drain pipe 56. One end of the drain joint 55 is communicated with the water extraction pipe 51, and the other end is for the drain pipe 56 to be inserted. The drain pipe 56 is provided with a marking portion 561 at the end inserted into the drain joint 55, and the marking portion 561 is used to mark the insertion depth of the drain pipe 56 into the drain joint 55.

When the end of the drain pipe 56 provided with the marking portion 561 is inserted into the drain joint 55, the insertion depth of the drain pipe 56 can be determined by observing the positional relationship between the marking portion 561 and the edge of the socket of the drain joint 55. In this way, it is convenient for the operator to determine the insertion depth of the drain pipe 56 into the socket joint, that is, it is convenient for the operator to determine whether the drain pipe 56 is installed in place, and reduces the risk that the drain pipe 56 falls off from the socket joint during the drainage process due to the too short insertion depth. Among them, the marking portion 561 can be a scale, a groove, a protrusion or a label, etc.
