It should be noted that, a person skilled in the art can flexibly set the number and the positions of the fans according to actual situations, for example, two fans (17a, 17b) can be set, and one or both of the fans can be operated according to different air supply requirements. Under the condition of general humidification requirements, one of the fans can be operated, so that the problems of noise, power use and the like possibly caused by the simultaneous operation of the two fans are avoided on the premise that the humidification target can be realized. And under the condition that the humidification demand is urgent, two fans can be enabled to operate simultaneously, and the humidification demand can be met in a short time by the arrangement.

The humidifying module comprises a humidifying box 21, and two side parts of the humidifying box are respectively provided with a first mounting position for mounting the spraying component 5. A transverse supporting frame 23 is installed in the humidifying box 21, and a plurality of second installation positions for installing the spraying component are arranged on the supporting frame. If two installation sites are installed with showers of the same specification, the first installation site and the second installation site should generally be the same. Of course, it is also possible to use different structures, such as one that is fixed by means of a snap fit, and one that is fixed by means of a screw connection. The spraying member has a pair of nozzles 55, which form a water film inside the chamber of the humidifying box after spraying water in a direction facing each other (for example, the speed of the sprayed water is 5-10m/s), and when the air flows through the water film at the position of the heat exchanger, the air collides with the water film and takes away part of the water in the water film, thereby increasing the humidity, and then the air is delivered to the indoor space through the air outlet, thereby realizing the humidifying function.

In addition, the second branch pipe extends outwardly with a ring stand 5221 at a position close to the nozzle, so that the nozzle is located just in the middle of the ring stand.

It can be seen that the flow path corresponding to the two nozzles consists of the first tube → the first branch → the second branch. In order to ensure the quality of the water film, the two pipelines corresponding to the nozzles are of a symmetrical structure. It can be understood that the structural flow channel of each pipe can also be in other composition forms, for example, the interior of the first pipe body is divided into two cavities, each cavity corresponds to the flow channel of one nozzle, the first branch pipe and the second branch pipe are arc-shaped pipes, the second branch pipe is a reducing structure along the water flow direction, and the like.

The first body has the third body 53 in the position that outwards extends corresponding to the end of intaking, corresponding position at the humidification box sets up porose 531, the part that stretches out the hole outside the third body has the external screw thread that can with the tube coupling, through dispose the connecting tube way (like the silicone tube) that matches with the external screw thread on the third body, can be connected to the outside water source with the component that sprays, so, after the water source lets in first body through the silicone tube, send a pair of nozzle of relative setting through (first, second) branch pipe respectively, water collides the production splash after nozzle department accelerates, form the water film of certain radius in the humidification box.

The humidifying box is provided with a second water discharging structure at a position close to the water receiving tray, namely, a region close to the bottom, so that water sprayed out of the nozzles is discharged out of the humidifying box after the water participates in humidifying treatment. If the second drainage structure includes the first drainage hole 211 and the second drainage hole 212 respectively disposed at the bottom of the humidification case and the bottom of the side walls of both sides of the humidification case, the second drainage hole preferably has a diameter less than or equal to that of the first drainage hole, so as to prevent water from splashing out of the humidification case from the second drainage hole in the process of colliding air with a water film as much as possible. Preferably, the water in the (first and second) drain holes is guided to the water pan and then drained out of the air conditioner, and of course, a drain pipe may be connected to any one of the holes to directly drain the water out of the air conditioner.

Taking the same first mounting position and the same second mounting position as the first mounting position and the second mounting position as the holes (531, 541) as an example, the mounting manner of the shower member 5 on the support frame will be described below with reference to the support frame 23.

Obviously, the aperture and the density of the air holes can be flexibly set according to actual conditions, such as uniformity or non-uniformity, the aperture of each air hole can be the same or different, and the like. In addition, the communicating structure can also be any other structure except the air holes, such as a strip-shaped hole, a star-shaped hole and the like.

The air conditioner may have different humidification mechanisms according to a specific form of the first open structure. Specifically, the method comprises the following steps:

in the case where the first open structure includes only the first opening, the air conditioner humidifies air of the indoor space by a front air humidifying process of: under the effect of fan, the indoor air is taken into the casing inside, and the inside air of casing passes the first water blocking net 41 of humidification module, slows down and gets into the humidification box, then through the water film and with the water film bump and take away partial liquid in the water film in-process that passes the water film thereby realized the increase of air humidity, later reaches the outside of humidification box through third water blocking net 43, finally gets into indoor space through the supply-air outlet. The circulation is carried out, so that the air in the indoor space can be humidified;

in the case where the first open structure includes only the second opening, the air conditioner humidifies the air of the indoor space by a top air humidifying process of: under the action of the fan, indoor air is pumped into the shell, the air in the shell passes through the humidifying box-the second water blocking net 42 of the humidifying module, is decelerated and enters the humidifying box, then passes through the water film, collides with the water film and passes through the water film, and takes away part of liquid in the water film so as to increase the air humidity, then reaches the outside of the humidifying box through the third water blocking net 43, and finally enters the indoor space through the air supply outlet. The air in the indoor space can be humidified by circulating the air humidifying device.

In the case where the first open structure includes the first opening and the second opening, the air conditioner humidifies air of the indoor space by a mixed air humidifying process of:

under the action of the fan, indoor air is pumped into the shell, the air in the shell is divided into two paths, the two paths of air respectively pass through the first water retaining net 41 and the humidifying cover-second water retaining net 42 of the humidifying module to be decelerated and enter the humidifying box, then pass through the water film, collide with the water film and pass through the water film to take away part of liquid in the water film so as to increase air humidity, then pass through the third water retaining net 43 to reach the outside of the humidifying box, and finally enter the indoor space through the air supply opening. The air in the indoor space can be humidified by circulating the air humidifying device.
