The driving motor part 9 drives the first wind control structure 61 to close, and the second wind control structure 104 is in an open state. At this time, most of the air passing through the evaporator 3 flows toward the cool air duct part 10 and then flows toward the outside of the whole machine. There is a constant opening (third air inlet 622) in the first air duct 62. Therefore, a small part of air passing through the evaporator 3 flows to the dehumidification air channel part 6, and dry air generated by the dehumidifier air channel flows to the outside of the whole machine (the condenser 5 generates heat, a normal opening is arranged to discharge part of the generated heat through air flow, and a small part of cold air passing through the evaporator can dissipate heat for the condenser 5, so that the dehumidification efficiency is improved). In order to maximize the refrigeration, the rotation speed of the second motor 102 can be increased and the rotation speed of the brushless motor (the first fan 63) can be reduced through the control function, and at the moment, the air volume of the cold air duct is larger than that of the dehumidification air duct. If the hot drying air does not need to be exhausted indoors, the air outlet can be connected with an exhaust pipe to exhaust the hot air outdoors.

4. When the high-efficiency dehumidification mode is started, the air flows in the direction shown in fig. 7. The driving motor part 9 drives the first wind control structure 61 to open, and the second wind control structure 104 is in a closed state. All the air passing through the evaporator 3 at this time flows toward the dehumidifying air channel part 6. The air generated by the evaporator 3 is fully used for dehumidification, and the maximum utilization rate of dehumidification capacity is realized. At this time, the cool air duct part 10 does not circulate air, and the second motor 102 can be turned off by the control function. The same can be achieved by adjusting the speed of the first fan 63 to adjust the dehumidification capacity.

The working state of the dehumidifier has a powerful refrigeration mode, a high-efficiency dehumidification mode and a refrigeration and dehumidification mode. Under powerful refrigeration mode, close dehumidification wind channel air intake, maximum efficiency is to user's specific position cold blast cooling, and the dehumidifier wind channel is provided with a normal open air intake, so has the dehumidification function simultaneously. And in the high-efficiency dehumidification mode, the cold air duct is closed, and all air passing through the evaporator enters the dehumidification air duct, so that the maximum dehumidification capacity is realized. In the refrigeration dehumidifier mode, two air channels simultaneously output air, the upper air outlet is used for outputting cold air, and the lower air outlet is used for outputting hot air, so that the functions of simultaneously refrigerating and dehumidifying are realized

In some embodiments, when a communication hole is further provided where the first air duct 62 and the second air duct 103 meet, and a sealing structure 15 is provided at the communication hole:

and in the control step, when the mode required by the cold air type dehumidifier is a high-efficiency dehumidification mode, the sealing structure 15 is controlled to move to open the communication hole, so that part of the gas subjected to heat exchange by the condenser 5 enters the second air duct 103, and part of the gas still flows in the first air duct 62.

The utility model discloses the accessible is between condenser and brushless motor, but the closing plate of switch is newly increased to the wind channel lateral wall. When the machine starts the high-efficiency dehumidification mode, the sealing plate is in an opening state. The humid air enters the evaporator from direction C. The state of the air control plate of the air channel is controlled and adjusted, so that the air passing through the evaporator is converged and flows to the dehumidification air channel, and then passes through the condenser to generate dry air. One part of the generated dry air is blown out of the machine along the original track and can be blown out of the machine through another air duct (multi-directional air outlet, more uniform indoor air and improved use comfort). At the moment, the upper air outlet and the lower air outlet are dry air, so that efficient and multidirectional simultaneous heat dissipation can be realized.
