It can be understood that if d1/d2>1.2, that is, the rotation axis of the first wind deflector 131 is close to the rear end of the first wind deflector 131, when the first wind deflector 131 rotates to the second position, the distance between the rear end of the first air deflector 131 and the volute 121 is relatively large, which will cause part of the cold wind to flow from the rear end of the first air deflector 131 to the volute 121 The gap between them flows to the ground, which will cause the user's head to be hot and feet to be cold, which affects the user's experience comfort. If d1/d2<0.8, that is, the rotation axis of the first wind deflector 131 is close to the front end of the first wind deflector 131, when the first wind deflector 131 rotates to the first position, the The distance between the front end of the first air deflector 131 and the volute tongue 122 is relatively large, which will cause part of the hot air to flow out from the gap between the front end of the first air deflector 131 and the volute tongue 122. The hot air density is small and easy to rise, which is not conducive to directing the hot air vertically to the ground to achieve "floor heating", which in turn affects the user's experience comfort. Considering comprehensively, in order to improve the comfort of the wall-mounted air conditioner indoor unit 100 in the cooling/heating state, d1/d2∈[0.8, 1.2] can be set.

Here, the structure of the air guide part 123 is not specifically limited, for example, the air guide part 123 may be a plane structure or an arc structure. The guide part 123 has a guide surface facing the first wind guide plate 131, and the distance between the rotation axis of the first wind guide plate 131 and the guide surface of the guide part 123 is greater than or equal to The distance between the rear end of the first wind deflector 131 and the rotation axis of the first wind deflector 131 . In one embodiment, in order to further increase the air outlet area of the air outlet 112 while reducing noise, the air guiding portion 123 can be made into an arc-shaped structure protruding backward.

Referring to FIGS. 1 to 4 , the wall-mounted air conditioner indoor unit 100 further includes a second air guide mechanism 140, and the second air guide mechanism 140 includes a second air guide plate 141 and a second driving device.

The second driving device is used to drive the second wind deflector 141 to rotate, so as to open or close the air outlet 112 .

Wherein, in one embodiment, the rotation axis of the second wind deflector 141 is located at the end of the second wind deflector 141; it can be understood that in other embodiments, the rotation axis of the second wind deflector 141 The rotation axis can also be located at the middle or the end of the second wind deflector 141 . The second wind deflector 141 has a second rotating shaft 142 located on its rotation axis, and the second wind deflecting plate 141 can rotate along the second rotating shaft 142 to open or close the air outlet 112 . When the second air guide plate 141 is in the open state, the front end of the second air guide plate 141 protrudes from the air outlet 112; when the second air guide plate 141 is in the closed state, the second air guide plate 141 The plate 141 covers the air outlet 112 .

In order to avoid interference between the first wind deflector 131 and the second wind deflector 141 , the rotation of the first wind deflector 131 and the second wind deflector 141 can be independently controlled. Specifically, the wall-mounted air conditioner indoor unit 100 further includes an electric control board, and the electric control board is separately connected to independently control the first driving device and the second driving device. Please refer to FIG. 3 , in the heating state, the electric control board can control the first air deflector 131 to rotate to the first position through the first driving device, and at the same time control the second air deflector 141 to be closed through the second driving device In this way, the hot air can be vertically directed to the ground by the first air deflector 131, so as to realize "floor heating". Please refer to FIG. 4 , in the cooling state, the electric control board can control the first air deflector 131 to rotate to the second position through the first driving device, and at the same time control the second air deflector 141 to be in the open state through the second driving device In this way, the cold air is blown forward under the combined action of the first air deflector 131 and the second air deflector 141 , which prevents the cold air from flowing down and causing the user's head to be hot and feet to be cold.

There may be various structures and shapes of the wind deflector, for example, the wind deflector may be arranged in a flat plate shape, or the wind deflector may be arranged in an arc shape. Please refer to FIG. 3 and FIG. 4 , in one embodiment, the first air deflector 131 is arranged in an arc; and/or, the second air guide 141 is arranged in an arc. It can be understood that according to the Coanda effect, the airflow will follow the arc flow path of the air deflector, so that in the heating state, more heat seals can be directed vertically to the ground; at the same time, in the cooling state, the cold air can be directed Guided to the front and upward, it is beneficial to make the indoor temperature distribution more uniform, and further improve the comfort of the wall-mounted air conditioner indoor unit 100 .

Considering that in order to make the wall-mounted air conditioner indoor unit 100 have a windless air outlet effect and further improve the comfort of use of the wall-mounted air conditioner indoor unit 100 , ventilation holes can be provided on the air guide plate. For example, in one embodiment, a plurality of first air diffuser holes are opened on the first air deflector 131 , so that the wind sent out through the first air diffuser holes can achieve a windless wind effect. In another embodiment, a plurality of second air diffuser holes are provided on the second air deflector 141 , so that the wind sent out through the second air diffuser holes can achieve a windless wind effect. Of course, in yet another embodiment, a plurality of first air diffuser holes are provided on the first air guide plate 131, and at the same time, a plurality of second air diffuser holes are provided on the second air guide plate 141, so that The wind sent out through the first air diffuser hole and the second air diffuser hole can achieve a windless wind effect.

Specifically, the diameter of the first diffuser hole is 1 mm to 10 mm, and the diameter of the second diffuser hole is 1 mm to 10 mm. The hole spacing between the plurality of first ventilation holes is 2 mm to 20 mm, and the hole spacing between the plurality of second ventilation holes is 2 mm to 20 mm. What needs to be explained is that if the aperture of the diffuser hole (the first diffuser hole and the second diffuser hole) is too small, the wind resistance will be increased, and the air volume will be reduced at the same time, which will reduce the cooling and heating efficiency of the air conditioner; If the aperture of the diffuser hole is too large, it is not conducive to achieving a windless air supply effect, which will cause discomfort to the user. Therefore, the diameter of the diffused air holes is 1mm˜10mm. Specifically, the diameter of the diffuse air holes may be 1mm, 2mm, 2.5mm, 3mm, 5mm, 7mm, 10mm, etc.

In one embodiment, the diameter of the first diffuser hole is smaller than the diameter of the second diffuser hole. It should be noted that the wind in the air duct 113 after heat exchange by the heat exchanger 150 can be blown out from the first air diffuser hole and the second air diffuser hole respectively, since the first air deflector 131 is located at the Below the second wind deflector 141121, that is, the distance between the second wind deflector 141 and the person is greater than the distance between the first wind deflector 141 and the person; The diameter of the first diffuser hole, so the air volume blown from the first diffuser hole is less, and the air volume blown from the second diffuser hole is more, thereby further preventing the air blown by the air conditioner from blowing directly to people. At the same time, the air supply volume can be increased to improve the cooling and heating effect of the air conditioner.

Of course, in other embodiments, the aperture diameter of the first diffuser hole and the aperture diameter of the second diffuser hole may also be equal. It is not limited here.

The utility model also proposes an air conditioner, which includes an air conditioner outdoor unit and a wall-mounted air conditioner indoor unit 100, and the wall-mounted air conditioner indoor unit 100 is connected to the air conditioner outdoor unit. The specific structure of the wall-mounted air conditioner indoor unit 100 refers to the above-mentioned embodiments. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments. Let me repeat them one by one.

The above is only a preferred embodiment of the present utility model, and does not therefore limit the scope of the patent of the present utility model. Under the inventive concept of the present utility model, the equivalent structural transformation made by using the specification of the utility model and the contents of the accompanying drawings, or Direct/indirect application in other related technical fields is included in the patent protection scope of the present utility model.
