The first air guiding plate 120 is rotatably disposed on the housing 100 with a first pivot 121 disposed adjacent to the rear wall surface 112. The second air guiding plate 130 is rotatably disposed on the housing 100 by a second pivot 131, and the second pivot 131 is located between the first pivot 121 and the front wall surface 111. An edge of the second air deflector 130 adjacent to the second pivot 131 is adapted to be in contact with an edge of the first air deflector 120 that is away from the first pivot 121.

It should be noted that the tangentially extending surface is a virtual plane and refers to a plane that is tangential to and extends from the edge of the rear wall surface 112 of the air duct 110. In the cooling mode, the first air deflector 120 preferably overlaps the tangentially extending surface. Of course, in practical applications, the first air deflector 120 can swing a certain angle in the vicinity of the tangentially extending surface. No specific restrictions. The second air deflector 130 is rotatable to a position substantially parallel to the first air deflector 120, so that the air duct 110 can be further extended to increase the air supply distance. Of course, the second air deflector 130 can also swing in the air outlet area of the air outlet to change the wind direction, thereby meeting different needs of the user. In order to prevent the third air deflector 140 from generating resistance to the airflow, in the cooling mode, the third air deflector 140 is preferably disposed to the front wall surface 111 of the air duct 110.

In the case of the heating mode, as shown in FIG. 3, the first air deflector 120, the second air deflector 130, and the third air deflector 140 can be rotated to a position close to a vertical position to direct the airflow downward. In order to maximize the flow of hot air to the ground. Since the heat flow density is low, it will rise upwards, which can give the user a better heating experience and achieve the "warm foot" function. In addition, in the heating mode, the first air deflector 120 can also be kept substantially perpendicular to the ground, and the second air deflector 130 and the third air deflector 140 can swing in parallel to change the wind direction, so that the hot air flow can be sent to the air. Far distance.

In the case of the windless mode, as shown in FIG. 4 to FIG. 6 , the first air deflector 120 and the second air deflector 130 can cooperate with each other to guide the airflow horizontally, and avoid the airflow to directly blow the human body, and adjust The position of the third air deflector 140 is such that the airflow can be softened by the air diffusing action of the diffuser hole 142 of the third air deflector 140, thereby realizing a true windless feeling, so as to give the user a better windless Feeling experience.

The technical solution of the present application is configured to provide a first air guiding plate 120, a second air guiding plate 130, and a third air guiding plate 140 on the casing 100 of the air conditioning indoor unit, and through the first air guiding plate 120 and the second air guiding plate 130.

In the heating mode, the first air deflector 120, the second air deflector 130, and the third air deflector 140 can cooperate with each other to direct the airflow downward, so that the warm air flow is directed to the ground as much as possible to achieve warmth. Foot effect. In the windless mode, the first air deflector 120, the second air deflector 130, and the third air deflector 140 can cooperate with each other to guide the airflow horizontally without directly blowing the human body, and the third guide can be further adjusted. The rotational position of the wind plate 140 allows the airflow to be blown out of the air diffusing holes 142 of the third air guiding plate 140, thereby achieving a better windless function. The air conditioner indoor unit of the present application can effectively be compatible with the cooling, heating and windless functions, and gives the user more mode selection, thereby effectively improving the user's experience comfort.

Specifically, in this embodiment, as shown in FIG. 7 and FIG. 8, the second air deflector 130 is designed to be similar to an aircraft frame structure, and the second air deflector 130 includes an air guiding portion 132 and a tail fin 133, and the tail fin 133 is The air guiding portion 132 is formed in a stepped manner to form a cavity 134. Thus, in the windless mode, the front end of the first air deflector 120 is rotated into the cavity 134 and abuts the tail fin 133 of the second air deflector 130, so that the first wind deflector 120 and the second wind deflector 120 can be made A sealing fit is achieved between the air deflectors 130 to prevent airflow from leaking out of the gap between the two to affect the windless effect.

Further, a width between a side of the air guiding portion 132 away from the second pivot 131 and a side of the air guiding portion 132 close to the second pivot 131 is W, wherein ∈ [100mm, 300mm]. In the present embodiment, the second air deflector 130 adopts an elongated design such that when in the cooling mode, the airflow is blown further when passing through the second air deflector 130 due to the Coanda effect of the airflow. In the heating mode, the airflow can be more directed to the ground under the effect of the Coanda effect, thereby effectively improving the cooling and heating effects. The width of the air guiding portion 132 may be 100 mm, 200 mm, 300 mm, etc. The wider the air guiding portion 132 is, the better the effect of extending the air duct 110 is. However, in practical applications, the production cost and the specific size of the air conditioner indoor unit must be taken into consideration. Make settings.

Further, an end of the first wind deflector 120 away from the first pivot 121 is provided with a first inclined surface 122, and the first inclined surface 122 faces away from the windward side of the first wind deflector 120. The first pivot shaft 121 is formed to extend obliquely.

One side. Specifically, in the present embodiment, the first pivot shaft 121 is disposed on the tangentially extending surface of the rear wall surface 112, or the first pivot shaft 121 is disposed on the tangentially extending surface of the rear wall surface 112. One side of the front wall surface 111 is such that the edge gap between the first pivot shaft 121 and the air outlet of the air duct 110 is as small as possible, so that airflow can be effectively prevented from leaking out from the gap, thereby affecting the user experience. Preferably, the first pivot shaft 121 is disposed on a side of the tangentially extending surface of the rear wall surface 112 that faces away from the front wall surface 111 such that a rear side edge of the first wind deflector 120 and an air outlet edge of the rear wall surface 112 are formed. The misalignment can effectively reduce the gap between the first air deflector 120 and the air outlet of the air duct 110 to prevent air leakage, and at the same time ensure that the first air deflector 120 can rotate to a large extent with the tangential extension surface of the rear wall surface 112. The position is to extend the air passage 110 to increase the air supply distance.

When the air conditioner is in operation, the first air deflector 120 and the second air deflector 130 are directly contacted by the airflow blown by the air outlet, so that the temperature difference between the two sides of the first air deflector 120 and the second air deflector 130 is higher. Large, the surfaces of the first air deflector 120 and the second air deflector 130 are prone to condensation, thereby affecting user comfort. To solve this problem, the first wind deflector 120 and/or the second wind deflector 130 are further provided with a heat insulating layer 150. Preferably, the heat insulating layer 150 is disposed on the windward side of the first wind deflector 120 and the second wind deflector 130, and the formation of condensation can be effectively avoided. The heat insulating layer 150 can be made of inorganic fiber materials, such as mineral wool, rock wool, glass wool, etc.; or can be made of organic heat insulating materials, such as polyethylene (PE) foam, polystyrene (PS) foam, polyurethane ( PU) foam, etc. In addition, the heat insulating layer 150 may be disposed inside the first wind deflector 120 and the second wind deflector 130.

In the embodiment, the accommodating groove 114 is provided, so that the third air deflector 140 can be accommodated in the accommodating groove 114 in the cooling mode, thereby avoiding resistance to the airflow and affecting the wind. The depth of the accommodating groove 114 may be set according to the thickness of the third air guiding plate 140. Preferably, when the third air guiding plate 140 is rotated into the accommodating groove 114, the notch edge of the accommodating groove 114 and the third air guiding body The outer surface of the plate 140 is substantially flush, or the third air deflector 140 is completely hidden in the receiving groove 114.

Since the air diffusing holes 142 are staggered, the airflows are disturbed by each other after passing through the air diffusing holes 142, and interference is generated to further reduce the wind speed and make the airflow softer. There are various shapes of the air diffusing holes 142. Preferably, the air diffusing holes 142 have a circular or elongated shape. Of course, the air diffusing holes 142 may also be a diamond shape, a square shape, or the like.

A method for controlling an indoor unit of an air conditioner according to an embodiment of the present application is described in detail below with reference to FIG. 1 to FIG. 11. The air conditioner indoor unit is an air conditioner indoor unit according to the above embodiment of the present application, and the air conditioner indoor unit includes a windless mode and cooling. The mode and the heating mode, the specific structure of the air conditioner indoor unit refers to the above embodiment, and will not be further described herein.

First, turn on the air conditioner indoor unit and select the air outlet mode. Specifically, a plurality of buttons are provided on the panel of the air conditioner indoor unit or the air conditioner remote controller, and different air outlet modes are selected by different buttons.

In the case where the windless mode is selected, the first wind deflector 120 and the second wind deflector 130 are rotated to derive the airflow level. Specifically, as shown in FIG. 4, the first air deflector 120 and the second air deflector 130 are both rotated to a position substantially parallel to the horizontal plane, so that the airflow can be horizontally exported, thereby preventing the airflow from directly blowing the human body, thereby effectively reducing the user's Wind experience.

In the case where the cooling mode is selected, the first wind deflector 120 is rotated to direct the airflow to the second wind deflector 130. Specifically, as shown in FIG. 2, the first wind deflector 120 is rotated to a position where the tangentially extending surface of the rear wall surface 112 of the air duct 110 is largely overlapped, and the rear end of the first air deflector 120 and the air duct 110 are at this time. The rear wall surface 112 is misaligned, which is equivalent to extending the air passage 110, so that the pressure of the tuyere can be effectively increased, so that the air supply distance is further. It should be noted that, in this mode, the second air deflector 130 can be rotated to a position substantially parallel to the first air deflector 120, so that the air duct 110 can be further extended to increase the air supply distance. It is also possible to control the second air deflector 130 to swing in the air outlet area of the air outlet to change the wind direction, thereby satisfying different needs of the user. In order to prevent the third air deflector 140 from generating resistance to the airflow, in the cooling mode, the third air deflector 140 is preferably disposed to the front wall surface 111 of the air duct 110.

In the case where the heating mode is selected, the first wind deflector 120 and the second wind deflector 130 are rotated to direct the airflow downward. Specifically, as shown in FIG. 3, the first air deflector 120, the second air deflector 130, and the third air deflector 140 are controlled to rotate to a position close to a vertical position to guide the airflow downward, thereby maximizing the airflow. Blow hot air to the ground. Since the heat flow density is low, it will rise upwards, which can give the user a better heating experience and achieve the "warm foot" function.
