Embodiment example 1
[0052] In the cooling working mode, after the user turns on the fresh air supply, the fresh air device works, and the fan 16 runs. The air conditioner judges the indoor humidity at this time, and the indoor humidity is greater than 70%. Wind, do not humidify the fresh air, judge whether there is water in the water storage mechanism 2 at this time, the first water tank 21 stores condensed water, the second water tank 22 stores pure water, and judges whether the pure water stored in the second water tank 22 is lower than 1 / 4, the pure water stored in the second water tank 22 is higher than 1 / 4, and the condensed water is preferentially used. When the fresh air enters the second air inlet 112, the filter screen 113 filters the fresh air for dust removal. After the fresh air enters, it passes through the coiled air intake pipeline 114 , the air inlet conveying pipe 114 first passes through the lower receiving pool, and then the fresh air is blown out after passing through the spra...
Embodiment example 2
[0054] As an alternative implementation case of Example 1, in the cooling mode, after the user turns on the fresh air supply, the fresh air device works, the fan 16 runs, and the air conditioner judges the indoor humidity at this time, and the indoor humidity is less than 70%, and the second air inlet 112 is closed. Wind, the first air inlet 111 is opened to take in the air, and the fresh air is humidified. It is judged whether there is water in the water storage mechanism 2 at this time, the first water tank 21 stores condensed water, and the second water tank 22 stores pure water. 22 Whether the purified water stored in the second water tank 22 is lower than 1 / 4, the purified water stored in the second water tank 22 is higher than 1 / 4, and the condensed water is used preferentially. When the fresh air enters the first air inlet 111, the fresh air can enter the purification through the first air inlet 111 In the spraying area, the filter screen 113 filters the fresh air for du...
Embodiment example 3
[0056] As an alternative implementation case of implementation case 2, in the cooling mode, after the user turns on the fresh air supply, the fresh air device works, the fan 16 runs, and the air conditioner judges the indoor humidity at this time, and the indoor humidity is greater than the user-defined humidity X% when the humidification is turned on Or the user decides to turn on the humidification, the second air inlet 112 is turned on, the first air inlet 111 is turned off, the fresh air is not humidified, and it is judged whether there is water in the water storage mechanism 2 at this time, and the first water tank 21 stores no condensed water , the second water tank 22 stores pure water, judge whether the pure water stored in the second water tank 22 is lower than 1 / 4, the purified water stored in the second water tank 22 is higher than 1 / 4, choose to use pure water, the second water tank 22 stores When the pure water is lower than 1 / 4, the user will be reminded to add wa...
