The flow path line of the air is shown by the dotted line in fig. 2 and 3. Air is sucked from the outside of the shell 1 under the rotation action of the fan blades 4, is purified through the filter screen 2, then reaches a second ventilation space formed between the support cylinder 6 and the annular wet curtain 7 through an air duct in the air duct 3, passes through the peripheral wall of the annular wet curtain to blow out or bring out water mist, and the water mist is discharged from the air outlet structure 12 to the periphery, so that the air is humidified. When the humidity sensor 14 detects that the humidity of the air is higher than a second preset humidity, for example, higher than 60%, the blower stops working.

The heating device 10 can heat the water in the water supply tray 9 to accelerate the volatilization when the indoor temperature is low, especially in winter. The heating device 10 heats water when the indoor temperature is not higher than a first preset temperature, continues heating when the water temperature is not higher than a second preset temperature, and stops heating when the water temperature is higher than a third preset temperature. Specifically, the first preset temperature may be 15 ℃ to 20 ℃, the second preset temperature may be 30 ℃ to 35 ℃, and the third preset temperature may be 60 ℃ to 65 ℃.

In the embodiment, the annular wet curtain 7 is arranged to increase the contact area of the wet curtain and water, and the air outlet structure 12 allows water mist to be discharged from the side walls of the shell 1 in all directions instead of only one side wall or one direction, so that the atomization area is maximized. The heating device 10 is arranged to enable the water in the water feeding disc 9 to be kept within a certain temperature threshold value, so that the water can be atomized quickly during humidification, and discomfort caused by overhigh temperature of the mist is prevented.

Example two

The embodiment provides a control method for applying the air purification humidifier in the first embodiment to the indoor environment, and the specific humidification control principle is as follows:

when the humidity of indoor air is monitored to be not higher than a first preset humidity, controlling a fan to start humidifying work to humidify the air; and when the humidity is higher than a second preset humidity, controlling the fan to stop humidifying.

When the indoor temperature is not higher than the first preset temperature, the heating device 10 is controlled to start heating, the water temperature in the water supply tray 9 is monitored, when the water temperature is not higher than the second preset temperature, the heating device 10 is controlled to continue heating, and when the water temperature is higher than the third preset temperature, the heating device 10 is controlled to stop heating.

Specifically, as shown in fig. 4, when the air humidity is not higher than 40% or 35%, the blower starts to perform humidification operation to humidify the air, monitors the air humidity in real time, and stops the humidification operation when the air humidity is monitored to be higher than 60% or 65%. When the air humidity is higher than 40% or 35%, the indoor temperature is monitored, when the indoor temperature is not higher than 20 ℃ or 25 ℃, the heating device 10 starts to heat the water in the water supply tray 9, the water temperature in the water supply tray 9 is monitored in real time, when the water temperature is not higher than 30 ℃ or 35 ℃, the heating device 10 continues to heat the water in the water supply tray 9, and when the water temperature is higher than 60 ℃ or 65 ℃, the heating device 10 stops heating.

In addition, before the heating device 10 starts heating, the water level 18 in the water supply tray 9 can be monitored, and when the water level 18 does not reach the rated water level, the water storage device 8 is controlled to supplement water to the water supply tray 9 to the rated water level. The water storage device 8 can be controlled to draw back the water in the water supply tray 9 when the fan stops humidifying.

In the control method provided by the embodiment, in the working process of the humidifier, if the indoor temperature is low, the water in the water supply tray 9 is heated first and is preheated for standby, so that the humidifying speed is increased. Especially, when the temperature is lower in winter, the air can be humidified as soon as possible. Meanwhile, the water temperature is controlled within a certain temperature threshold value, so that the temperature of the water mist sprayed out of the humidifier is comfortable and pleasant. In addition, timely replenishing water to the water supply tray 9 can ensure that the water supply tray 9 is filled with sufficient water before the heating device 10 heats the water, and the heating device 10 is prevented from being dried. After the humidifier stops humidifying, water in the water supply tray 9 is pumped back, and therefore the phenomenon that water flows out of the water supply tray 9 by mistake to cause a circuit short circuit and even damage humidifier components can be prevented.
