The pump body assembly 100 of the dehumidifier 500, and a control method thereof according to an embodiment of the present invention will be described with reference to fig. 1 to 7.

As shown in fig. 1 to 7, in the pump body assembly 100 of the dehumidifier 500 according to the embodiment of the present invention, the dehumidifier 500 has a water tank 530 for containing condensed water. The pump body assembly 100 includes: pump body 10, drive motor 20 and magnetic member 30.

Specifically, as shown in fig. 1, 2 and 5, the pump body 10 has an impeller 110, and the pump body 10 is located in a water tank 530. Thus, the pump body 10 can pump out the water in the water tank 530. The driving motor 20 is disposed outside the water tank 530, so that the driving motor 530 can be prevented from being damaged by moisture, and the maintenance and replacement of the driving motor 530 are facilitated. The magnetic member 30 is located between the pump body 10 and the driving motor 20, and the driving motor 20 drives the pump body 10 to rotate through the magnetic member 30. Thus, when the driving motor 20 rotates, the pump body 10 in the water tank 530 may be driven to rotate by the magnetic member 30 to pump the water in the water tank 530.

According to the pump body assembly 100 of the dehumidifier 500 of the embodiment of the invention, the pump body 10 is arranged inside the water tank 530, the driving motor 20 is arranged outside the water tank 530, and the magnetic member 30 is arranged between the driving motor 20 and the pump body 10, so that when the driving motor 20 rotates, the pump body assembly 100 can be driven to rotate through the magnetic member 30 to pump out water in the water tank 530, and the dehumidifier 500 is simple and compact in structure and low in cost. Moreover, the driving motor 20 and the pump body assembly 100 are indirectly driven by the magnetic member 30, so that the problem of water leakage of the water tank 530 due to the communication hole formed in the water tank 530 is avoided. In addition, the driving motor 20 is disposed outside the water tank 530, so that the driving motor 20 is effectively prevented from being damaged by moisture, and the driving motor 20 is convenient to repair and replace.

According to some embodiments of the present invention, as shown in fig. 2 and 5, the magnetic member 30 may include: a first magnetic block 310 and a second magnetic block 320. The first magnetic block 310 is pivotally disposed on the pump body 10, and the first magnetic block 310 is connected to the impeller 110. When the first magnetic block 310 rotates, the first magnetic block 310 drives the impeller 110 to rotate. The second magnetic block 320 is pivotally connected to the driving motor 20, and when the driving motor 20 rotates, the motor shaft 210 of the driving motor 20 drives the second magnetic block 320 to rotate. It should be noted that, when the driving motor 20 drives the second magnetic block 320 to rotate, the second magnetic block 320 may drive the first magnetic block 310 to rotate through a magnetic force. Moreover, when the first magnetic block 310 rotates, the impeller 110 can be driven to rotate together. Therefore, the rotation of the driving motor 20 is transmitted to the impeller 110 of the pump body 10 by the magnetic force between the first magnetic block 310 and the second magnetic block 320 to drive the impeller 110 to rotate, thereby pumping out the water in the water tank 530.

In some embodiments of the present invention, as shown in fig. 2 and 5, the first magnetic block 310 is engaged with the impeller 110, and the second magnetic block 320 is engaged with the motor shaft 210 of the motor. Therefore, the first magnetic block 310 and the second magnetic block 320 are convenient to assemble and connect, so that the assembly efficiency of the first magnetic block 310 and the second magnetic block 320 can be improved, and the production cost can be reduced. As shown in the examples of fig. 2 and 5, an impeller clamping groove may be provided on the impeller 110, and the first magnetic block 310 is inserted and clamped into the impeller clamping groove. An assembling portion 211 is provided at the end of the motor shaft 210 of the driving motor 20, and a groove is provided on the assembling portion 211 to snap-fit the second magnetic block 320 into the groove. Thus, the assembly efficiency of the first and second

magnetic blocks

310 and 320 is improved.

Alternatively, as shown in fig. 1 and 2, the first and second

magnetic blocks

310 and 320 may each have a ring shape. Therefore, the processing and manufacturing of the first magnetic block 310 and the second magnetic block 320 are facilitated, and the production cost of the first magnetic block 310 and the second magnetic block 320 is reduced. It can be understood that the first magnetic block 310 and the second magnetic block 320 are arranged in a ring shape, so that the first magnetic block 310 can be conveniently assembled with the circular impeller 110, the second magnetic block 320 can be conveniently assembled with the pivot shaft of the driving motor 20, and when the first magnetic block 310 and the second magnetic block 320 rotate, the ring-shaped structural design can enable the first magnetic block 310 and the second magnetic block 320 to have good smoothness.

According to some embodiments of the present invention, as shown in fig. 1 and 2, the pump body 10 is connected to the water tank 530, and the pump body 10 is located at the bottom of the water tank 530. It will be appreciated that by locating the pump body 10 at the bottom of the water tank 530, the water in the water tank 530 can be pumped out more thoroughly. It should be noted that, as shown in fig. 1, the inner side wall of the water tank 530 may be provided with a fitting groove adapted to the outer shape of the pump body 10, so as to snap-fit the pump body 10 into the fitting groove, thereby facilitating the fixed assembly of the pump body 10. Of course, the assembly manner between the pump body 10 and the water tank 530 is not limited thereto, and the pump body 10 may be assembled to the inner sidewall of the water tank 530 by screwing or welding. As shown in fig. 1 and 2, the drive motor 20 is disposed opposite to the pump body 10. Thereby, it is convenient for the magnetic member 30 to transmit the rotation of the driving motor 20 to the pump body 10 to drive the rotation of the motor 20, thereby improving the reliability of the operation of the pump body assembly 100.

In some embodiments of the invention, the magnetic member 30 may be an electromagnet or a permanent magnet. That is, the magnetic member 30 may alternatively use an electromagnet, and may alternatively use a permanent magnet. For example, the second magnetic block 320 of the driving motor 20 may optionally use an electromagnet, which has good magnetic properties, and the magnetic properties of the electromagnet can be controlled by controlling the current of the electromagnet, thereby improving the reliable stability of the operation of the pump body assembly 100. The magnetic member 30 may also be a permanent magnet, and it will be appreciated that the permanent magnet is inexpensive and reduces the manufacturing and operating costs of the pump body assembly 100.

According to the dehumidifier 500 of the embodiment of the present invention, the dehumidifier 500 includes: a bottom plate 510, a drip tray 520, a control module (not shown), a water tank 530, and the pump body assembly 100.

Specifically, as shown in fig. 1 to 5, the base plate 510 is located at a lower end (in an up-down direction as shown in fig. 1 and 4) of the dehumidifier 500 to fixedly support the dehumidifier 500. The water receiving pan 520 is connected to the bottom plate 510, and the water receiving pan 520 is located above the bottom plate 510 (in the up-down direction as shown in fig. 1 and 4). Thus, the water vapor in the air is condensed into water droplets by the dehumidifier 500, and the water droplets are dropped into the water tray 520.

As shown in fig. 6 and 7, the water tray 520 is provided with a control switch 521, and the control switch 521 can transmit information on the water level in the water tank 530 and whether the water tank 530 is installed in the dehumidifier 500.

The control module is arranged on the chassis 510 and is connected with the control switch 521. Thus, the control module can control the operation of the pump body assembly 100 based on information communicated by the control switch 521.

The water tank 530 is movably disposed between the water-receiving tray 520 and the bottom plate 510, so that the accumulated water in the water-receiving tray 520 can flow into the water tank 530 below for centralized treatment. And the water tank 530 is movably fitted between the water tray 520 and the bottom chassis 510, so that the water tank 530 can be removed to pour water when the water tank 530 is full of water. A floating block 531 is arranged in the water tank 530, and the floating block 531 is selectively connected with the control switch 521. Thus, the closing of the control switch 521 may be controlled by the float 531 to transmit the water level condition in the water tank 530 to the control module through the float 531.

The pump body assembly 100 is arranged in the water tank 530, the pump body 10 is connected with a water pipe 532 communicated with the outside of the water tank 530, and the driving motor 20 is connected with the control module. Thus, the control module may control the operation of the driving motor 20, and then drive the pump body assembly 100 to pump the water in the water tank 530 out of the water tank 530 through the water pipe 532.

It should be noted that, when the dehumidifier 500 is not equipped with the water tank 530, the control switch 521 is in an off state; as shown in fig. 7, when the dehumidifier 500 is installed in the water tank 530 and the water in the water tank 530 is not full, the floating block 531 touches the control switch 521 to make the control switch 521 in a closed state; as shown in fig. 6, when the dehumidifier 500 is installed in the water tank 530 and the water tank 530 is full of water, the floating block 531 is rotated by the buoyancy, and the control switch 521 is turned off.

According to the dehumidifier 500 of the embodiment of the invention, the control switch 521 is arranged on the water receiving tray 520, the floating block 531 capable of controlling the control switch 521 is arranged in the water tank 530, and the chassis 510 is provided with the control module which is connected with the control switch 521 and the driving motor 20. Therefore, the control switch 521 can be controlled to be turned on or off through the floating block 531 to transmit information about whether the water tank 530 is full and whether the dehumidifier 500 is provided with the water tank 530, and transmit the information to the control module, the control module can control the driving motor 20 according to the related information transmitted by the control switch 521, and then the driving motor 20 drives the pump body 10 to rotate through the magnetic member 30, so that the water tank 530 drains more intelligently and reliably.

According to some embodiments of the present invention, the float 531 may be provided with a touch portion 5311, and the touch portion 5311 may be selectively connected to the control switch 521. Thus, the control switch 521 can be controlled to be turned on or off by the touch portion 5311. As shown in fig. 6 and 7, the float 531 may be connected to the inside of the water tank 530 at the upper side by a pivot shaft (not shown). When the water tank 530 is mounted on the dehumidifier 500 and the water in the water tank 530 is not full, the touch portion 5311 of the floating block 531 stops the control switch 521, so that the control switch 521 is in a closed state. When the water tank 530 is removed from the dehumidifier 500, the control switch 521 is in an off state without the abutment of the touch portion 5311 of the floating block 531. When the water tank 530 is assembled to the dehumidifier 500 and the water tank 530 is full of water, the floating block 531 rotates about the pivot shaft by the floating force and the control switch 521 is in an off state by the touch part 5311. Therefore, the touch part 5311 of the floating block 531 controls the on/off of the control switch 521, so that the information about whether the dehumidifier 500 is equipped with the water tank 530 and whether the water tank 530 is full can be converted into the on/off of the control switch 521, and the control switch 521 transmits a corresponding signal to the control module to control whether the pump body assembly 100 drains water into the water tank 530.

According to the control method of the dehumidifier 500 of the embodiment of the present invention, the dehumidifier 500 is the dehumidifier 500, and the control method includes:

detecting the state of the control switch 521, and starting the driving motor 20 when the control switch 521 is in an off state; it can be understood that when the control switch 521 is in the off state, which indicates that the water tank 530 is not installed in the dehumidifier 500 or the water tank 530 is full, the control module starts the driving motor 20.

After time T1, the state of the control switch 521 is detected again, and if the control switch 521 is turned off, the driving motor 20 stops operating; it can be understood that, after the time T1, if the control switch 521 is still in the off state, it indicates that the off state of the control switch 521 is caused by the fact that the water tank 530 is not installed in the dehumidifier 500, and at this time, the control module controls to stop the operation of the driving motor 20.

If the control switch 521 is in the closed state, the driving motor 20 continues to operate, and after a time T2 elapses, the driving motor 20 stops operating. It can be understood that, after the time T1, if the control switch 521 is in the closed state, it indicates that the control switch 521 is turned off because the dehumidifier 500 is in the full water state, and therefore, the driving motor 20 continues to operate to drain the water tank 530, and the water in the water tank 530 is pumped up to the rated water level after the time T2.

According to the control method of the dehumidifier 500 provided by the embodiment of the invention, the state of the control switch 521 is detected by the control module to judge the water level condition in the water tank 530, and when the water tank 530 is full of water, the water tank 530 is automatically drained, so that the drainage of the water tank 530 of the dehumidifier 500 is intelligentized, and the performance of the dehumidifier 500 is further improved.

According to the control method of the dehumidifier 500 of the embodiment of the present invention, the dehumidifier 500 is the dehumidifier 500, and the control method includes: the state of the control switch 521 is detected, and when the control switch 521 is turned off, information that water needs to be poured or the water tank 530 is not filled is displayed. It is understood that when the control switch 521 is in the off state, it indicates that the dehumidifier 500 is not installed with the water tank 530 or the water tank 530 is full, and thus, the dehumidifier 500 displays the information that the water needs to be poured or the water tank 530 is not installed, so that the user can perform the corresponding operation.

According to the control method of the dehumidifier 500 provided by the embodiment of the invention, when the control switch 521 is turned off, the dehumidifier 500 can display the information that water needs to be poured or the water tank 530 is not filled, so as to prompt a user to perform corresponding operation, thereby improving the running reliability and safety of the dehumidifier 500.

The pump body 10 has an impeller 110, and the pump body 10 is connected with a water pipe 532 communicating with the outside of the water tank 530. The driving motor 20 is located outside the water tank 530, the driving motor 20 is fixedly connected with the mounting part at the lower end of the water receiving tray 520, and the driving motor 20 is connected with the control module.

As shown in fig. 2 and 5, the magnetic member 30 is located between the pump body 10 and the driving motor 20. The magnetic member 30 includes: the first magnetic block 310 and the second magnetic block 320 are permanent magnets, and the first magnetic block 310 and the second magnetic block 320 are both in a ring shape. The first magnetic block 310 is clamped and assembled in an impeller clamping groove of the impeller 110; the second magnetic block 320 is snap-fitted to the fitting part 211 fitted to the end of the motor shaft 210.

It should be noted that, when the driving motor 20 rotates, the motor shaft 210 drives the second magnetic block 320 to rotate together. Under the action of the magnetic force, the second magnetic block 320 drives the first magnetic block 310 to rotate and drives the impeller 110 to rotate, so that the water in the water tank 530 is pumped out of the water tank 530 through the water pipe 532, and the water tank 530 is drained. As shown in fig. 4, water in the water tank 530 enters the pump body 10 and is discharged out of the water tank 530 through the water pipe 532 (as indicated by an arrow b1 → b2 in fig. 4).

The control steps of the drainage of the water tank 530 of the dehumidifier 500 are as follows:

the control module detects the state of the control switch 521, and if the control module is in the off state, it indicates that the water tank 530 is not installed in the dehumidifier 500 or the water tank 530 is full of water, and at this time, the control module controls to start the driving motor 20.

After the time T1, the controller detects the state of the control switch 521 again, and if the control switch 521 is still in the off state, it indicates that the off state of the control switch 521 is caused by the fact that the water tank 530 is not installed in the dehumidifier 500, and at this time, the control module controls to stop the operation of the driving motor 20; if the time T1 elapses, the controller detects that the control switch 521 is in the closed state, which indicates that the control switch 521 is in the open state in the above step is caused by the water tank 530 being full of water, and at this time, the control module controls the driving motor 20 to continue to operate to drive the pump body 10 to drain the water tank 530. After the time T2 elapses, the water in the water tank 530 is discharged to a rated water level, and the operation of the driving motor 20 is stopped.

Therefore, the control switch 521 is arranged on the water receiving tray 520, the floating block 531 capable of controlling the control switch 521 is arranged in the water tank 530, and the chassis 510 is provided with a control module which is connected with the control switch 521 and the driving motor 20. Therefore, the information of whether the water tank 530 is full or not and whether the dehumidifier 500 is provided with the water tank 530 or not can be transmitted by controlling the on/off of the control switch 521 through the floating block 531, and the information is transmitted to the control module, the control module can control the driving motor 20 according to the related information transmitted by the control switch 521, and then the driving motor 20 drives the pump body to rotate through the magnetic part 30, so that the water tank 530 drains more intelligently and reliably, and the overall performance of the dehumidifier is improved.
