The invention provides a dehumidifier.

Referring to fig. 1 to 3, in an embodiment of the present invention, the dehumidifier includes a water tank 70, a main body 10, a drain pump 20, and a water suction pipe 30, the main body 10 has an idle state and an operating state, and the main body 10 is provided with a drain level 15. In the idle state, the body 10 is at least partially received in the water tank 70. In the operating state, the body 10 is extended relative to the water tank 70. The water inlet end of the water discharge pump 20 is communicated with the water tank, and the water outlet end of the water discharge pump 20 is communicated with the water discharge level 15.

It can be understood that in the present embodiment, a dehumidifying apparatus 80 (refer to fig. 2 and 4) is provided in the body 10, and in an operating state, the dehumidified water generated by the dehumidifying apparatus 80 can fall into the water tank 70. Alternatively, the dehumidifying device 80 includes a compressor, an evaporator, and a condenser, and the evaporator condenses the water vapor in the air into water droplets to remove the water vapor in the air, and the condenser heats and dries the air from which the water vapor is removed to return the blown air to normal temperature. Of course, in other embodiments, the dehumidification device 80 may also adopt a dehumidification method such as an adsorption method.

When the body 10 is in an operating state, the body 10 is extended relative to the water tank 70, so that the bottom of the body 10 is spaced apart from the bottom of the water tank 70, and thus the dehumidification water generated by the dehumidification device 80 in the body 10 can be discharged into the water tank 70. The dehumidified water in the water tank 70 is pumped by the drain pump 20 and discharged from the drain site 15. The drain pump 20 may be operated to drain water during the operation of the dehumidifier 80 in the main body 10, or the drain pump 20 may be operated to drain water in the water tank 70 after the dehumidifier 80 in the main body 10 finishes the dehumidification operation. When the water in the water tank 70 is completely discharged, at least a part of the main body 10 can be accommodated in the water tank 70 so that the main body 10 is in an idle state. In the operating state, the drain level 15 may or may not be exposed outside the water tank 70.

In the technical scheme of the invention, the water tank 70 is externally arranged below the machine body 10 in the working state, and compared with the technical scheme that the water tank 70 is internally arranged in the machine body 10, the technical scheme enables the water tank 70 to have larger volume so as to accommodate more dehumidification water. Meanwhile, by providing the drain pump 20 at the body 10, the water inlet end of the drain pump 20 is communicated with the water tank 70, so that the water in the water tank 70 can be drained through the drain pump 20, the water in the water tank 70 can be drained without carrying the water tank 70, and the situation that a user carries the water tank 70 to pour water is reduced.

In this embodiment, when the body 10 is in an idle state, at least a part of the body 10 can be accommodated in the water tank 70, so that the center of gravity of the dehumidifier can be lowered, the dehumidifier is stably placed and is not prone to tilting, the overall occupied space of the dehumidifier is reduced, and a user can place the dehumidifier conveniently. When the body 10 is in a working state, the body 10 extends out relative to the water tank 70, so that the air outlet on the body 10 has a higher position, and the dehumidified air can be discharged to the higher position, and further can be diffused to the whole indoor space more quickly.

In one embodiment, the dehumidifier further includes a water pumping pipe 30, one end of the water pumping pipe 30 is connected to the water inlet end of the drainage pump 20, and the other end of the water pumping pipe 30 extends into the water tank 70. Namely, the drain pump 20 is fixed to the body 10 and extends into the water tank 70 through the water suction pipe 30 so as to draw the dehumidification water in the water tank 70, so that the structure is simple and the cost is reduced. Of course, in other embodiments, the water suction pipe 30 may not be provided, for example, the water suction pump 20 may be mounted to the body 10 to be movable up and down.

In one embodiment, the housing 19 of the body 10 is provided with a connector assembly 11, one end of the connector assembly 11 is communicated with the water inlet end of the drain pump 20, and the other end of the connector assembly 11 is communicated with the water pumping pipe 30. That is, the drain pump 20 is disposed in the body 10, and the drain pump 20 is connected to the pumping pipe 30 through the joint assembly 11, so as to facilitate installation of the pumping pipe 30 and the pipeline between the pumping pipe 30 and the drain pump 20. The joint assembly 11 may be integrally formed with the housing 19 of the body, or a recess may be formed in the housing 19, and the joint assembly 11 may be disposed in the recess, or the like. Of course, in other embodiments, a relief hole may be provided in the housing 19 of the body 10, so that the water suction pipe 30 passes through the relief hole and is connected to the drainage pump 20. In other embodiments, the drain pump 20 may be disposed outside the body 10, or the drain pump 20 may be disposed in the receiving recess by providing the receiving recess on the outer side surface and the bottom surface of the body 10.

In addition, the water inlet end of the drain pump 20 can be connected to the connector assembly 11 through a connection pipe 50, and the water outlet end of the drain pump 20 can be connected to the drain site 15 through a water outlet pipe 60. Of course, in other embodiments, the water inlet end of the drain pump 20 can be directly connected to the connector assembly 11, and the water outlet end of the drain pump 20 can be directly connected to the drain site 15.

In one embodiment, the connector assembly 11 is provided on the side of the housing 19. That is, the joint assembly 11 is located at the side of the body 10, which is equivalent to the water pumping pipe 30 connected to the side of the body 10, so that when the user detaches the water pumping pipe 30, the user can conveniently observe the position of the joint assembly 11, and the user can conveniently install the water pumping pipe 30 in an aligned manner. The user can conveniently check the connection state of the water pumping pipe 30 and the joint component 11, and the condition that the water pumping pipe 30 is not correctly connected or the user is not aware of when the water pumping pipe falls off can be avoided. Of course, in other embodiments, the joint assembly 11 may be disposed at the bottom of the fuselage 10.

In order to avoid the damage to the body 10 and the water tank 70 caused by the rigid abutment of the water pumping pipe 30 with the inner wall of the water tank 70, in one embodiment, the water pumping pipe 30 is a hose. It can be understood that when the pumping pipe 30 is provided as a hose, even if the distance between the outer side of the body 10 and the inner wall of the water tank 70 is smaller than the diameter of the pumping pipe 30, and the pumping pipe 30 is squeezed, the situation that the pumping pipe 30 is rigidly abutted between the water tank 70 and the body 10 is avoided, and the possibility of damage to the body 10 and the water tank 70 is reduced. But also can be conveniently stored by a user, and the pumping pipe 30 can be arranged to be long to be in contact with the bottom wall of the water tank 70. The rigid abutting of the water pumping pipe 30 and the bottom wall of the water tank 70 can be avoided, so that the lower end of the water pumping pipe 30 can be in good contact with the bottom wall of the water tank 70, and the water in the water tank 70 can be fully pumped out. Of course, in other embodiments, the suction tube 30 may be a rigid tube.

In order to reduce the interference between the water pumping pipe 30 and the inner side wall of the water tank 70, in an embodiment, the outer side surface of the housing 19 is provided with an avoiding groove 14, the avoiding groove 14 penetrates through the bottom of the machine body 10, and the joint component 11 is arranged at the bottom of the avoiding groove 14. Namely, the water pumping pipe 30 extends downwards into the water tank 70 through the avoiding groove 14, and the protruding height of the water pumping pipe 30 relative to the outer surface of the machine body 10 can be reduced by arranging the avoiding groove 14, so that when the machine body 10 is in a working state, the extrusion of the inner wall of the water tank 70 on the water pumping pipe 30 can be reduced, and the water pumping effect of the water pumping pipe 30 is ensured. The possibility that the machine body 10 is difficult to put into the water tank 70 due to the interference of the water pumping pipe 30 and the inner wall of the water tank 70 can be further reduced, and the possibility that the water pumping pipe 30 is damaged by pressure injury is reduced. In addition, after the avoidance groove 14 is arranged, the gap between the outer side surface of the machine body 10 and the inner wall of the water tank 70 can be reduced, so that the size of the water tank 70 is reduced, and the whole structure of the dehumidifier is more compact. Of course, in other embodiments, the relief groove 14 may not be provided.

In one embodiment, a plurality of avoidance grooves 14 are formed in the outer side surface of the housing 19, the avoidance grooves 14 are distributed at intervals along the circumferential direction of the fuselage 10, and the joint assembly 11 is arranged at the bottom of one of the avoidance grooves 14. The inner side surface of the water tank 70 is provided with a plurality of supporting protrusions (not shown), the plurality of supporting protrusions are distributed along the circumferential direction of the water tank 70 at intervals, in an idle state, the supporting protrusions extend into the avoiding groove 14, and in an operating state, the upper ends of the supporting protrusions support the bottom of the body 10.

Specifically, the avoidance groove 14 extends along the height direction of the fuselage 10, each support protrusion corresponds to at least one avoidance groove 14 matched with the support protrusion, that is, the number of the avoidance grooves 14 may be greater than that of the support protrusions, and each support protrusion is matched with at least one avoidance groove 14, so as to ensure that the fuselage 10 can be accommodated in the water tank 70. When the avoiding groove 14 provided with the joint component 11 is matched with one supporting convex part, so that the machine body 10 is accommodated in the water tank 70, the water pumping pipe 30 can be firstly detached, so as to avoid the interference between the water pumping pipe 30 and the supporting convex part.

It can be understood that the supporting convex portions are arranged along the circumferential direction of the water tank 70 at intervals, when the machine body 10 needs to be switched from the idle state to the working state, the machine body 10 can be lifted out of the water tank 70, and the machine body 10 is rotated by a certain angle relative to the water tank 70, so that the avoiding grooves 14 and the supporting convex portions are staggered with each other, and further, one end of the supporting convex portion is enabled to support the part, which is not provided with the avoiding groove 14, of the bottom of the machine body 10. So that the body 10 can be fixed in an operating state.

Wherein, a plurality of support convex parts can evenly be arranged along water tank 70's circumference to when guaranteeing fuselage 10 bottom and a plurality of support convex parts butt, fuselage 10 circumference atress is even, is favorable to improving the stability of fuselage 10 when operating condition. For example, when the number of the supporting protrusions is two, two supporting protrusions are provided at both opposite sides of the water tank 70, and so on. Of course, in other embodiments, when the number of the supporting protrusions is greater than or equal to three, the plurality of supporting protrusions may be arranged non-uniformly in the circumferential direction of the water tank 70. Further, the body 10 may have a cylindrical, elliptic cylindrical or prismatic shape, and the shape of the water tank 70 is adapted to the shape of the body 10. When the body 10 has a prismatic shape, it may have a square shape, a regular pentagonal shape, a regular hexagonal shape, or the like.

The structure of the joint assembly 11 can be varied, for example, in one embodiment, the joint assembly 11 includes a first pipe joint 12 and a second pipe joint 13, one end of the first pipe joint 12 is communicated with the water inlet end of the drain pump 20, and the other end is inserted into the housing 19. The second pipe joint 13 includes a first pipe connected to an end of the first pipe joint 12 exposed outside the housing 19 and a second pipe extending downward and connected to an end of the pumping pipe 30. Specifically, the first pipe joint 12 is fixed to the chassis 16 of the fuselage 10, the first pipe of the second pipe joint 13 is connected to the first pipe joint 12 from the outside of the housing 19, and the first pipe joint 12 is not higher than the groove bottom of the escape groove 14, that is, the first pipe joint 12 is recessed toward the housing 19 in the groove bottom of the escape groove 14 or flush with the groove bottom of the escape groove 14. The second pipe joint 13 is arranged substantially in an "L" shape. With this arrangement, the height of the second pipe joint 13 protruding from the outer surface of the housing 19 (body 10) can be reduced, and the height of the suction pipe 30 protruding from the outer surface of the body 10 can be reduced, thereby further reducing the possibility of damaging the suction pipe 30 by pressure damage. When the end of the first pipe joint 12 exposed from the abdicating hole is recessed or flush with the bottom of the avoiding groove 14, the interference between the first pipe joint 12 and the supporting convex part can be avoided when the avoiding groove 14 is matched with the supporting convex part.

In one embodiment, the first pipe joint 12 is detachably connected with the second pipe joint 13; and/or the suction pipe 30 is detachably connected to the second pipe. When the main body 10 is accommodated in the water tank 70, the second nipple 13 and/or the water suction pipe 30 may be removed to prevent the main body 10 from being normally accommodated in the water tank 70 due to interference between the second nipple 13 and the water suction pipe 30 and the water tank 70 during the process of accommodating the main body 10 in the water tank 70. Of course, in other embodiments, the first pipe joint 12 and the second pipe joint 13 may be integrally formed.

In order to avoid the interference between the first pipe joint 12 and the water tank 70, in one embodiment, the end of the first pipe joint 12 exposed outside the housing 19 is a female joint, the first pipe is a male joint, and the first pipe is at least partially inserted into the first pipe joint 12. The end of the first pipe joint 12 exposed outside the housing 19 is set to be recessed or flush with the outer side surface of the fuselage 10 compared to the outer side surface of the housing 19 (in the embodiment of the avoidance groove 14, the end of the first pipe joint 12 exposed outside the housing 19 is set to be recessed or flush with the groove bottom of the avoidance groove 14). Therefore, the first pipe joint 12 is prevented from protruding out of the outer side of the water tank 70, and when the body 10 is placed in the water tank 70, the first pipe joint 12 is prevented from protruding out of the outer side of the body 10 and interfering with the water tank 70.

To reduce the clogging of the drain pump 20 caused by the impurities such as dust particles entering the drain pump 20, in one embodiment, the end of the suction pipe 30 extending into the water tank 70 is provided with a filter member 40. That is, the filtering member 40 is disposed at the end of the pumping pipe 30 located at the bottom of the water tank 70 to filter the impurities such as dust particles in the water tank 70, thereby reducing the blockage of the drain pump 20 caused by the impurities entering the drain pump 20. Moreover, the filter member 40 is disposed outside the body 10 in such a manner as to be easily replaced. To facilitate replacement of the filter member 40 or the suction pipe 30, the filter member 40 is detachably attached to the suction pipe 30 in this embodiment. In addition, in other embodiments, the filter member 40 may be disposed at the connection of the joint assembly 11 and the pumping tube 30, or the filter member 40 may not be disposed.

When the filter member 40 is used for a long time, the impurities in the filter member 40 are accumulated to increase, which affects the water inflow amount of the pumping pipe 30, so that the filter member 40 needs to be replaced. In order to reduce the cost of replacing the filter element 40 for the user, in one embodiment, the filter element 40 includes an upper cover 41, a lower cover 42 and a filter screen, the upper cover 41 has a water outlet connected to the water pumping pipe 30, the lower cover 42 has a water inlet, the filter screen is disposed between the water outlet and the water inlet, and the upper cover 41 and the lower cover 42 are detachably connected. So when filtering a lot of impurity accumulations in the piece 40, the user can tear open upper cover 41 and lower cover 42 to can change the filter screen, so make upper cover 41 and lower cover 42 can reuse, be favorable to reducing the wasting of resources, need not change whole filtration piece 40 moreover, can reduce user use cost. Wherein, the upper cover 41 and the lower cover 42 can be connected by screws, or the upper cover 41 and the lower cover 42 are connected by a screw structure, or the upper cover 41 and the lower cover 42 are clamped, etc.

In one embodiment, the drain site 15 includes a drain support 151 disposed at a side of the body 10, the drain support 151 has a first port facing the inside of the body 10 and a second port facing the outside of the body 10, the water outlet end of the drain pump 20 is connected to the first port, and the second port is connected to a drain connector 152. It will be appreciated that the drain connector 152 is configured to allow external plumbing connections. In the present embodiment, the drain support 151 and the drain connector 152 are additionally provided, so that the water outlet pipe 60 of the drain pump 20 and the external pipeline can be attached to each other, and the water outlet pipe 60 of the drain pump 20 can be communicated with the external pipeline more conveniently. Optionally, to facilitate connection of external piping, the drain fitting 152 is a quick fitting. In addition, in order to ensure the sealing performance between the drain connector 152 and the external interface of the drain bracket 151 while the connection is achieved, optionally, the external interface of the drain bracket 151 is screwed with the drain connector 152.

In addition, referring to fig. 4 and 5, in some embodiments, the joint assembly may not be disposed at the side of the housing 19 (the body 10), for example, the joint assembly 11 may be disposed at the bottom plate 16 of the body 10, which corresponds to the connection of the water pumping pipe 30 at the bottom of the body 10, so as to avoid the interference of the water pumping pipe 30 with the inner side wall of the water tank 70 during the process of putting the body 10 into the water tank 70 or taking the body out of the water tank 70.

To facilitate the installation of the suction tube 30, in one embodiment, the adapter assembly 11 includes a third adapter 17, and one end of the suction tube 30 is connected to the third adapter 17. The third pipe joint 17 has various structures, for example, in this embodiment, the third pipe joint 17 is integrally formed on the outer surface of the chassis 16 (i.e., the surface of the chassis 16 facing away from the drain pump 20), and the water pumping pipe 30 is sleeved on the third pipe joint 17, so that the structure of the third pipe joint 17 is simple, the third pipe joint 17 can be formed together when the chassis 16 is formed, which is beneficial to simplifying the assembly process of the dehumidifier, and the connection mode between the water pumping pipe 30 and the third pipe joint 17 is simple, so as to facilitate the user operation. However, the design is not limited thereto, and in some embodiments, the third pipe joint 17 may be detachably connected to the chassis 16, for example, the third pipe joint 17 is a quick joint. In addition, in other embodiments, the third adapter 17 may not be provided, and the suction pipe 30 may be inserted into a through hole of the chassis, and so on.

In one embodiment, the suction tube 30 is removably connected to the third adapter 17. Thus, when the main body 10 is in the idle state, the water pumping pipe 30 can be detached to prevent the water tank 70, the main body 10 and the water pumping pipe 30 from being damaged due to the fact that the water pumping pipe 30 abuts between the bottom of the water tank 70 and the bottom of the main body 10 when the main body 10 is accommodated in the water tank 70. Of course, in other embodiments, the suction tube 30 and the third adapter 17 may be non-detachably connected, such as bonding or welding the suction tube 30 and the third adapter 17.

In order to avoid the interference between the third pipe joint 17 and the bottom wall of the water tank 70, in an embodiment, the outer surface of the chassis 16 is concavely provided with a receiving groove 161, the third pipe joint 17 is arranged at the bottom of the receiving groove 161, and the length of the third pipe joint 17 is not greater than the depth of the receiving groove 161. In this way, the third pipe joint 17 can be prevented from protruding from the notch edge of the housing groove 161, and when the body 10 is housed in the water tank 70, the third pipe joint 17 can be prevented from contacting the bottom wall of the water tank 70 when the notch edge of the housing groove 161 abuts against the bottom wall of the water tank 70. The structure of the chassis 16 forming the receiving groove 161 has various structures, for example, the receiving groove 161 may be formed at a position corresponding to the third pipe joint 17 on the outer surface of the chassis 16. The chassis 16 may be provided with a plurality of support ribs arranged in a staggered manner in a grid-like distribution or a spider-web-like distribution, and the plurality of support ribs may form the receiving grooves 161 therebetween. Of course, in other embodiments, the receiving groove 161 may not be provided.
