The water receiving assembly 200 includes a water tank compartment 210 and a water receiving tray 220 disposed on top of the water tank compartment 210. The water tank compartment 210 is mounted on the base 100 and is used to accommodate the main water tank 900. The water receiving tray 220 is used to receive condensed water generated by the dehumidifier during dehumidification. The water receiving tray 220 includes a water storage tank 221, a first drain hole 222, and a second drain hole 223. The first drain hole 222 and the second drain hole 223 are disposed in the water storage tank 221. The first drain hole 222 is used to connect the water storage tank 221 to the main water tank 900 mounted on the water tank compartment 210.

[0049] Figure 5 This is a perspective diagram of the base, auxiliary water tank, and water outlet pipe assembly in one embodiment of the dehumidifier of the present invention. The auxiliary water tank 300 is mounted on the base 100 and communicates with the second drain hole 223. The water outlet pipe assembly 400 is in communication with the auxiliary water tank 300.

[0050] Figure 6 This is a schematic exploded perspective view of the water receiving assembly and water pump in one embodiment of the dehumidifier of the present invention. The water pump 810 is disposed within the auxiliary water tank 300 and is connected to the water outlet pipe assembly 400. When activated, the water pump 810 is configured to transport liquid from the auxiliary water tank 300 outward through the water outlet pipe assembly 400.

[0051] A dehumidifier according to an embodiment of the present invention includes a base 100, a water receiving assembly 200, a secondary water tank 300, a water outlet pipe assembly 400, and a water pump 810. The water receiving assembly 200 includes a water tank compartment 210 and a water receiving tray 220 mounted on top of the compartment 210. The compartment 210 is used to hold the main water tank 900, and the water receiving tray 220 is used to collect condensed water generated by the dehumidifier during dehumidification. The water receiving tray 220 includes a water reservoir 221, a first drain hole 222, and a second drain hole 223.

When the water pump 810 is turned on, it is configured to discharge liquid from the secondary water tank 300 through the water outlet pipe assembly 400. Therefore, when the dehumidifier needs to use a water tank to collect condensed water, the first drain hole 222 on the water receiving pan 220 is connected to the main water tank 900 installed in the water tank compartment 210, thereby collecting the condensed water through the main water tank 900. When the condensed water needs to be directly transported to the outside, the second drain hole 223 on the water receiving pan 220 is connected to the auxiliary water tank 300 and the water outlet pipe assembly 400. After the water pump 810 is turned on, the condensed water generated by the dehumidifier during dehumidification operation is transported to the outside. In addition to collecting condensed liquid through the main water tank 900, the dehumidifier of the above technical solution can also use the water pump 810 to transport the condensed liquid to the outside through the auxiliary water tank 300 and the water outlet pipe assembly 400, thereby increasing the versatility of the dehumidifier's use scenarios.

Figure 8 The filter element 820 is detachably connected to the filter element mounting portion 320 , and the condensate in the second drain hole 223 flows into the water storage portion 310 after passing through the filter element 820 .

[0054] In the dehumidifier according to an embodiment of the present invention, filter element 820 is detachably connected to filter element mounting portion 320. Condensate from second drain hole 223 flows through filter element 820 and into water reservoir 310. The provision of filter element 820 eliminates the problem of solid impurities such as dust and lint in the environment mixing with the condensate during condensation, which can easily clog or damage water pump 810. It also addresses the problem of poor drainage caused by solid impurities in the condensate. The detachable connection of filter element 820 allows for regular cleaning and maintenance of filter element 820, improving the convenience of cleaning and maintenance and extending the lifespan of the dehumidifier.

[0055] In some embodiments, the filter element mounting portion 320 includes a mounting channel 321 for accommodating at least a portion of the filter element 820 , and a maintenance opening 211 communicating with the mounting channel 321 is provided on a side wall of the water tank compartment 210 .

When the protrusion block 821 is aligned with the notch T2, the filter element 820 can be inserted into or removed from the installation channel 321. When the filter element 820 is inserted into the installation channel 321 and the protrusion block 821 is misaligned with the notch T2, the protrusion block 821 is abutted against the limiting protrusion T1, so that the filter element 820 is limited to the installation channel 321.

In some embodiments, the second fluid circuit switch member 600 includes a mounting base 610 , a first movable rod 620 , a first elastic member 630 , and an electric drive member 640 .

[0072] The mounting seat 610 is disposed on the second drainage hole 223 , and the mounting seat 610 has a movable channel corresponding to the position of the second drainage hole 223 .

[0073] The first movable rod 620 is arranged in the movable channel and can be raised and lowered along the movable channel. A first sealing portion 621 is provided at the bottom of the first movable rod 620. The first movable rod 620 can be moved to a first position and a second position. In the first position, the first movable rod 620 causes the first sealing portion 621 to block the second drainage hole 223. In the second position, the first movable rod 620 causes the first sealing portion 621 to leave the second drainage hole 223, so that the second drainage hole 223 is opened.

[0074] The first elastic member 630 elastically connects the first movable rod 620 to the mounting seat 610 . The first elastic member 630 is used to reset the first movable rod 620 to the first position.

[0075] The electric drive member 640 is mounted on the mounting base 610 and is in transmission connection with the first movable rod 620.

[0076] Figure 11 This is a side view of a secondary water tank in one embodiment of a dehumidifier according to the present invention. In some embodiments, the dehumidifier further includes a controller. The secondary water tank 300 includes a water storage portion 310, a common conductive contact 330, a first liquid-level conductive contact 340, and a second liquid-level conductive contact 350. The water storage portion 310 is an insulator. The common conductive contact 330, the first liquid-level conductive contact 340, and the second liquid-level conductive contact 350 are located on the sidewalls of the water storage portion 310 and are signal-connected to the controller. The second liquid-level conductive contact 350 is located at a higher height than the first liquid-level conductive contact 340, and the first liquid-level conductive contact 340 is located at a higher height than or equal to the common conductive contact.

[0077] In some embodiments, when the condensed water level in the water storage portion 310 is lower than the position height of the first liquid level conductive contact 340, the first liquid level conductive contact 340 and the common conductive contact 330 generate a first disconnection signal; when the condensed water level in the water storage portion 310 is equal to or higher than the position height of the first liquid level conductive contact 340, the first liquid level conductive contact 340 and the common conductive contact 330 generate a first conduction signal.

[0078] In some embodiments, when the condensed water level in the water storage portion 310 is lower than the position height of the second liquid level conductive contact 350, the second liquid level conductive contact 350 and the common conductive contact 330 generate a second disconnection signal; when the condensed water level in the water storage portion 310 is equal to or higher than the position height of the second liquid level conductive contact 350, the second liquid level conductive contact 350 and the common conductive contact 330 generate a second conduction signal.

[0079] In some embodiments, the controller is configured to control the water pump 810 to turn on when receiving the second on signal; and the controller is configured to control the water pump 810 to turn off when receiving the first off signal.

[0080] In this embodiment, the water pump 810 is, for example, a centrifugal water pump, which has a longer lifespan than other types of water pumps.

[0081] In the above embodiment, the liquid level in the auxiliary water tank 300 is sensed by the common conductive contact 330, the first liquid level conductive contact 340, and the second liquid level conductive contact 350. Compared with the solution of using a proximity switch to sense the liquid level and the solution of using a float structure to sense the liquid level, the problem of the proximity switch or the float being stuck can be avoided, and the reliability is better.

[0082] The controller is configured to control the water pump 810 to turn on when it receives the second conduction signal, and the controller is configured to control the water pump 810 to turn off when it receives the first disconnection signal, so that the condensed water can be discharged in time when the liquid level in the auxiliary water tank 300 is high, and the water pump 810 can be turned off in time when the liquid level in the auxiliary water tank 300 is low, so as to avoid the water pump 810 from failing due to dry pumping.

A second sealing portion 4221 is provided at one end of the second movable rod 422. The second movable rod 422 can move to a third position and a fourth position. In the third position, the second movable rod 422 causes the second sealing portion 4221 to block the stepped channel. In the fourth position, the second movable rod 422 causes the second sealing portion 4221 to open the stepped channel. The second elastic member 423 is used to reset the second movable rod 422 to the third position.

[0085] In some embodiments, the dehumidifier also includes a drain pipe assembly 700, which includes a drain pipe 710 and a drain connector 720 located at one end of the drain pipe 710. The drain connector 720 is detachably connected to the one-way valve interface 420. When the drain connector 720 is connected to the one-way valve interface 420, the insertion portion 721 of the drain connector 720 extends into the one-way valve interface 420 and pushes the second movable rod 422 to the fourth position.

[0086] Figure 13 This is a partial perspective diagram of the base and drain pipe assembly in one embodiment of a dehumidifier according to the present invention. In some embodiments, the drain connector 720 further includes a snap-fit ​​portion 722 disposed on the outer periphery of the insert portion 721. The base 100 is provided with a retaining groove 110. When the drain connector 720 is connected to the one-way valve interface 420, rotation of the drain connector 720 about the central axis of the insert portion 721 causes the snap-fit ​​portion 722 to engage or exit the retaining groove 110.
