the humidifying system also comprises two heat exchangers and two guide plates, the two heat exchangers are arranged on two opposite sides of the water pan, the two guide plates are arranged on two opposite ends of the water pan, and the two heat exchangers and the two guide plates are mutually connected to form an air supply duct together; a gap is formed between at least one of the two guide plates and the water pan, and when the fan runs, a negative pressure area is formed in the air supply duct to suck external air from the gap;
the steam jet is communicated with the air supply duct, the fan is arranged close to the outlet of the air supply duct, and when humidification is performed, the fan operates to feed steam sprayed from the steam jet and outside air sucked from the gap into the air outlet duct of the air conditioner after the air supply duct is mixed.
2. The humidification system of claim 1, wherein the volume of the chamber is greater than the volume of vapor output by the vapor delivery tube per unit time, and wherein the vapor decreases in pressure and velocity as it flows through the chamber.
3. The humidification system of claim 2, further comprising the fan, wherein the fan is disposed between the water pan and the inlet of the air outlet duct, and sends the vapor flowing through the cavity into the air outlet duct.
4. The humidification system as claimed in claim 3, wherein the walls of the water pan cooperate to form the chamber, an air inlet is formed in a bottom wall of the chamber, and an output end of the steam delivery pipe is connected to the air inlet.
5. The humidification system of claim 1, wherein the humidification device is provided with an exhaust port, the input end of the steam delivery pipe is connected with the exhaust port, and the humidification device is further provided with a water filling port.
6. The humidification system of claim 1 or 5, wherein the humidification device is an electrode humidifier, an infrared humidifier or an electro-thermal humidifier.
7. An air conditioner characterized in that it comprises a humidification system as claimed in any one of claims 1 to 6.
8. A humidifying method of an air conditioner according to claim 7, comprising the steps of:
detecting the humidity of the indoor environment every preset time;
when the humidity is smaller than a preset threshold value, controlling the humidifying device to start to operate to generate steam;
and inputting the steam into the cavity of the water receiving disc and then sending the steam into an air outlet duct of the air conditioner to humidify the indoor environment.
9. The humidification method of claim 8, wherein the steam is mixed with air after flowing through the chamber, and then is sent to an air outlet duct of an air conditioner to humidify an indoor environment.
