[0048] The outer drainage pipe 23 and the inner drainage pipe 24 are arranged to form the outer channel and the inner channel, which facilitates the selection of suitable drainage channels according to different drainage modes, and the drainage connector 40 and the outer drainage pipe 23 are arranged to be detachably connected, which facilitates the replacement of the drainage connector 40 and facilitates the maintenance and repair; the inner drainage pipe 24 passes through the outer drainage pipe 23, which simplifies the component structure, optimizes the internal space layout, and improves the compactness of the equipment.

[0050] As shown in the figure, Figure 9 , Figure 10As shown, the drain connector 40 includes a first connector 41 and a second connector 42, which are respectively detachably connected with the outer drain pipe 23; wherein, in the case of using continuous drainage mode, the first connector 41 is connected with the outer drain pipe 23, and the outer channel and the inner channel are both communicated with the channel in the first connector 41; in the case of using water pump drainage mode, the second connector 42 is connected with the outer drain pipe 23, and the inner channel is communicated with the channel in the second connector 42, while the outer channel is not communicated with the channel in the second connector 42. By replacing different drain connectors 40, the switching between continuous drainage and water pump drainage can be realized, ensuring that the drainage system of the dehumidifier can stably operate under different drainage modes.

[0051] As shown, Figure 9 the outer drain pipe 23 has external threads, the first connector 41 has internal threads, and the first connector 41 is threadedly connected with the outer drain pipe 23; the drain connector 40 further includes a first sealing gasket 43, which is arranged between the end face of the outer drain pipe 23 and the inner wall of the first connector 41, and the inner diameter of the first sealing gasket 43 is greater than the outer diameter of the inner drain pipe 24, so that the outer channel is communicated with the channel in the first connector 41 through the gap between the first sealing gasket 43 and the inner drain pipe 24. By using the threadedly connected mode, the disassembly is facilitated, and by the double sealing of the threadedly connected mode and the first sealing gasket 43, the sealing performance of the dehumidifier in the continuous drainage mode is significantly improved, and the risk of condensate leakage is reduced.

[0052] As shown, Figure 10 the outer drain pipe 23 has external threads, the second connector 42 has internal threads, and the second connector 42 is threadedly connected with the outer drain pipe 23; the drain connector 40 further includes a second sealing gasket 44, which is arranged between the end face of the outer drain pipe 23 and the inner wall of the second connector 42, and the inner diameter of the second sealing gasket 44 is smaller than the inner diameter of the inner drain pipe 24, so that the second sealing gasket 44 abuts against the end face of the inner drain pipe 24, and the outer channel is spaced from the channel in the second connector 42.

[0055] The connection position between the drain joint 40 and the drainage channel is located above the opening of the water tank 50.

The overflow port 22211 is also positioned below the upper edge of the water receiving tray 22, and the horizontal distance between the outlet of the drainage channel and the upper edge of the water tank 50 is greater than 3 mm. The provision of the overflow port 22211 facilitates the transfer of overflow water into the water tank 50, preventing equipment failures caused by excessively high water levels and improving the safety of the dehumidifier.

[0057] The embodiment of the present application also provides a control method for the above-described dehumidifier adopting the water tank drainage mode, which comprises the following steps: detecting whether the water in the water tank 50 reaches a first set water level during the dehumidification process of the dehumidifier; in the case that the water in the water tank 50 reaches the first set water level, the dehumidifier stops dehumidification and sends an alarm information to prompt the user to pour out the water in the water tank 50; detecting whether the water in the second water storage groove 2223 reaches a second set water level during the dehumidification process of the dehumidifier; in the case that the water in the second water storage groove 2223 reaches the second set water level, the dehumidifier stops dehumidification and sends an alarm information to prompt the user to clean the dirt blockage; in the case that the water in the water tank 50 does not reach the first set water level and the water in the second water storage groove 2223 does not reach the second set water level, the dehumidifier normally operates.

[0058] Through the real-time monitoring of the first water level sensor 62 and the second water level sensor 63, the intelligent control of the dehumidifier under the water tank drainage mode is realized, the equipment can be automatically stopped when the water level in the water tank and the water level in the second water storage groove 2223 are too high, the equipment damage is prevented, the operation state is automatically adjusted according to the water level change, the user is prompted to pour out the water in the water tank 50 or clean the dirt blockage of the equipment through the alarm, and the safety of the equipment and the user satisfaction are improved.

[0059] The embodiment of the present application also provides a control method for the above-described dehumidifier adopting the continuous drainage mode, which comprises the following steps: detecting whether the water in the second water storage groove 2223 reaches a second set water level during the dehumidification process of the dehumidifier; in the case that the water in the second water storage groove 2223 reaches the second set water level, the water pump 30 is started to drain water outwards through the water pump 30; after the water pump 30 is started for a set time, the water in the second water storage groove 2223 is still not lower than the second set water level, the dehumidifier stops dehumidification and sends an alarm information to prompt the user to clean the dirt blockage.

[0060] Through the real-time monitoring of the second water level sensor 63, the intelligent control of the dehumidifier under the continuous drainage mode is realized, the water pump is automatically started to drain water when the water level is too high, the equipment is stopped to operate when the water pump drainage is invalid due to the dirt blockage, the equipment damage is prevented, the operation state is automatically adjusted according to the water level change, the user is prompted to clean the dirt blockage of the equipment through the alarm, and the safety of the equipment and the user satisfaction are improved.

[0061] In the embodiment, the control method further comprises: detecting whether the water in the water tank 50 reaches a first set water level during the dehumidification process of the dehumidifier; in the case that the water in the water tank 50 reaches the first set water level, the dehumidifier stops dehumidification and sends an alarm information to prompt the user to reconnect the drain connector 40 and pour out the water in the water tank 50; in the case that the water in the water tank 50 does not reach the first set water level and the water in the second water storage groove 2223 does not reach a second set water level, the dehumidifier operates normally.

[0062] Through real-time monitoring of the first water level sensor 62 and the second water level sensor 63, it is ensured that the equipment automatically stops when the water tank 50 is full, preventing damage to the equipment. When the continuous drainage mode is usually adopted, the water in the water tank 50 will not reach the first set water level, so if the alarm rings at this time, it means that the user needs to check the connection of the drain connector 40 and reconnect it, improving the operating efficiency and safety of the equipment.

[0063] The embodiment of the application further provides a control method for the dehumidifier, and the control method comprises: detecting whether the water in the second water storage groove 2223 reaches a second set water level during the dehumidification process of the dehumidifier; in the case that the water in the second water storage groove 2223 reaches the second set water level, starting the water pump 30 to drain water outside through the water pump 30; detecting whether the water in the water tank 50 reaches a first set water level during the dehumidification process of the dehumidifier; in the case that the water in the water tank 50 reaches the first set water level, the dehumidifier stops dehumidification and sends an alarm information to prompt the user to reconnect the drain connector 40 and pour out the water in the water tank 50; in the case that the water in the water tank 50 does not reach the first set water level and the water in the second water storage groove 2223 does not reach the second set water level, the dehumidifier operates normally.

[0064] Through real-time monitoring of the first water level sensor 62 and the second water level sensor 63, intelligent control of the dehumidifier in the water pump drainage mode is realized, ensuring that the equipment automatically starts the water pump drainage when the water in the second water storage groove 2223 reaches the second set water level, and automatically stops when the water tank 50 is full, preventing damage to the equipment. Under normal circumstances, when the water pump drainage mode is adopted, the water in the water tank 50 will not reach the first set water level, so if the alarm rings at this time, it means that the user needs to check the connection of the drain connector 40 and reconnect it, improving the operating efficiency and safety of the equipment.
