The air volume adjusting member 160 is movably installed at the first air outlet 122, and the air volume adjusting member 160 is used for adjusting the air volume of the first air outlet 122.

In the embodiment of the present invention, the indoor unit 100 of the air conditioner specifically relates to an indoor unit 100 of a wall-mounted air conditioner, but is not limited thereto. The air-conditioning indoor unit 100 includes an outer casing 110, the outer casing 110 includes a face frame 120 and a chassis 130, the face frame 120 is mounted on the chassis 130, and the face frame 120 and the chassis 130 together form an inner cavity for mounting internal components (such as a fan assembly and a heat exchanger) of an air conditioner. The top of face frame 120 is equipped with air intake 121, the air inlet department installs the air inlet grid, the bottom of face frame 120 is equipped with first air outlet 122, can realize the air-out downwards, the preceding downside of face frame 120 is equipped with second air outlet 123, can realize air-out forward. A heat exchange air duct communicating the air inlet 121, the first air outlet 122, and the second air outlet 123 is formed inside the housing 110. The housing 110 further includes a front panel 140, wherein the front panel 140 is installed at the front side of the face frame 120 and is located above the second air outlet 123, so that the second air outlet 123 is not covered by the front panel 140.

The first air outlet 122 penetrates through the bottom of the face frame 120, and the first air outlet 122 extends along the length direction of the face frame 120. The air volume adjusting member 160 is movably installed at the first air outlet 122, and is used for adjusting the air volume of the first air outlet 122. The air volume adjuster 160 may be movably installed at the first outlet 122 in many ways, for example, the air volume adjuster 160 may be rotatably installed at the first outlet 122, and the air volume adjuster 160 may be slidably installed at the first outlet 122. Specifically, the air volume adjusting member 160 is rotatably connected to the face frame 120, or the air volume adjusting member 160 is slidably connected to the face frame 120, which is not particularly limited. The air volume adjusting member 160 may have various structures, for example, the air volume adjusting member 160 may be a micro-perforated plate or a grid plate, and the air volume adjusting member 160 may also be a wind deflector, that is, a structure without a wind passing hole, and is not particularly limited herein. The air volume adjusting member 160 may be configured to adjust the air volume of the first outlet 122. The user can control the position of the air volume adjusting member 160 according to the actual use requirement, so as to adjust the air outlet area of the first air outlet 122, and further adjust the air volume of the first air outlet 122. Specifically, when the user needs a strong wind sensation, that is, the user needs a large air output of the first air outlet 122, the air volume adjusting member 160 does not block the first air outlet 122, or the area of the first air outlet 122 blocked by the air volume adjusting member 160 is reduced, so that the air output area of the first air outlet 122 is large, and the first air outlet 122 has a large air output; when the user needs a weaker wind, that is, the user needs a smaller air output of the first air outlet 122, the air volume adjusting member 160 at least partially covers the first air outlet 122, so that the air outlet area of the first air outlet 122 is reduced, and the air output of the first air outlet 122 is reduced.

When the air diffuser 180 is in the closed position, the air diffuser 180 is located at the second air outlet 123, and the second air outlet 123 is blocked, so that the air flow inside the air conditioner can only pass through the air diffuser 180 and be blown out through the air diffuser 180. The overall shape of the air diffuser 180 is adapted to the shape of the first air outlet 122, and the air diffuser 180 diffuses the air flowing to the first air outlet 122, so that the air flows in a diffused manner, that is, the air flows can flow in different directions by changing the original flowing direction after passing through the air diffuser 180, thereby realizing diffused flow of air and achieving a non-wind-feeling air outlet effect. The specific structure of the air diffuser 180 may include an air diffuser grid structure, a cyclone wind wheel structure, a multi-layer air diffuser hole plate structure, etc., and only needs to diffuse the air flow passing through it, which will be described in detail below.

The technical scheme of the utility model is that a first air outlet 122 is arranged at the bottom of a face frame 120, a second air outlet 123 is arranged at the front lower side of the face frame 120, an air dispersing device 180 is arranged at the second air outlet 123, and the air dispersing device 180 is provided with an opening position for opening the second air outlet 123 and a closing position for closing the second air outlet 123; meanwhile, the air volume adjusting member 160 is installed at the first air outlet 122, and the air volume adjusting member 160 can adjust the air volume of the first air outlet 122; thus, when the air diffuser 180 is in the closed position, the air flow inside the air conditioner can pass through the air diffuser 180 and be blown out through the air diffuser 180, so that no-wind-sensation air outlet is realized, at the moment, the air outlet quantity of the first air outlet 122 can be adjusted through the air quantity adjusting member 160, if the air outlet quantity of the first air outlet 122 is increased through the air quantity adjusting member 160, the air outlet quantity in the no-wind-sensation mode can be increased, so that the wind sensation in the no-wind-sensation mode is enhanced; if the air volume of the first outlet 122 is reduced by the air volume adjusting member 160, the air volume in the no-wind-sensation mode can be reduced, so that the wind sensation in the no-wind-sensation mode is weakened. Therefore, the utility model discloses an air conditioning indoor unit 100 can adjust the air output under the no wind sense mode, and then promotes the air-out of no wind sense and experiences.

Preferably, the air volume adjusting member 160 is slidably mounted on the upper surface of the first outlet grille 150, so that the air volume adjusting member not only can adjust the outlet area of the first outlet grille 150, but also can ensure the overall aesthetic property of the indoor unit 100 of the air conditioner. Considering that the air volume adjusting member 160 can slide on the upper surface of the first outlet grill 150, the area of the air volume adjusting member 160 needs to be smaller than the area of the first outlet grill 150. In addition, in order to facilitate the air volume adjusting member 160 to slide on the upper surface of the first outlet grill 150, the upper surface of the first outlet grill 150 may be a smooth surface, so that the sliding friction between the air volume adjusting member 160 and the first outlet grill 150 may be reduced.

In the above embodiments, the indoor unit 100 of the air conditioner further includes an inner air deflector 190 and a louver assembly 191, the inner air deflector 190 and the louver assembly 191 are both installed in the heat exchange air duct, and the louver assembly 191 is located upstream of the inner air deflector 190 in the air outlet direction. The inner air deflector 190 and the louver assembly 191 both have a guiding effect on the air flow. In order to further improve the overall no-wind effect of the indoor unit 100 of the air conditioner, the inner air deflector 190 may be provided with a wind dispersing hole.

The utility model discloses still provide an air conditioner, this air conditioner includes machine 100 in air condensing units and the air conditioning, machine 100 in the air conditioning pass through the refrigerant pipe with the air condensing units is connected. The specific structure of the air conditioner indoor unit 100 refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
