The housing 40 has therein an air duct for circulating air, the air duct having an air outlet provided on an outer peripheral wall of the housing 40. When the air conditioner indoor unit 100 is turned on, wind is continuously blown to the indoor space through the air outlet, thereby adjusting the indoor temperature. For example, when the air conditioning indoor unit 100 is in the air-conditioning feeling mode, the air conditioning indoor unit 100 sends out warm air from the air outlet of the casing 40, and when the air conditioning indoor unit 100 is in the air-conditioning feeling mode, the air conditioning indoor unit 100 sends out air from the air outlet.
The housing 40 includes a chassis 41, a face frame 42, and a panel 43; the face frame 42 is provided on the chassis 41, the front side of the face frame 42 is open, the panel 43 is provided on the front side of the face frame 42, and an air outlet is defined between the lower end of the panel 43 and the face frame 42. Specifically, the face frame 42 may be rotatably or detachably provided on the chassis 41, and the panel 43 may be rotatably or detachably provided on the face frame 42. It will be appreciated that the indoor unit 100 further includes a fan 50 and the like disposed within the housing 40.
The first wind deflector 10 is rotatably provided on the housing 40 for opening or closing the wind outlet. The first air guide plate 10 can be rotated about the first air guide plate rotation shaft 11 to open or close the air outlet. For example, when the air conditioner indoor unit 100 is turned off, the first air guide plate 10 rotates around the first air guide plate rotating shaft 11 to close the air outlet, and when the air conditioner indoor unit 100 is turned on, the first air guide plate 10 rotates around the first air guide plate rotating shaft 11 to open the air outlet, thereby facilitating the air supply of the air conditioner indoor unit 100 to the indoor.
The second air deflector 20 is rotatably disposed on the housing 40 and located on the inner side of the first air deflector 10 (for example, on the side near the center of the housing 40), while the third air deflector 30 is rotatably disposed on the inner wall of the air duct, and the third air deflector 30 is located on the inner side of the first air deflector 10 (for example, on the side near the center of the housing 40); preferably, the air duct is provided with a containing groove for containing the third air deflector 30, and the depth of the containing groove is equal to the thickness of the third air deflector 30, so that the air outlet of the air duct is not affected when the third air deflector 30 is contained in the containing groove. The second air deflection 20 and the third air deflection 30 are rotatable about a second air deflection axis 22 and a third air deflection axis 32, respectively. The end of the third air deflector 30 facing the air outlet is rotatably provided on the housing 40. In the specific example of the present invention, the first air deflector 10 and the second air deflector 20 are respectively provided on the face frame 42, and the third air deflector 30 is provided on the chassis 41; the second air deflection 20 is located downstream of the third air deflection 30 in the direction of air flow.
The second air guide plate 20 is provided with a plurality of first air diffusing holes 21 penetrating the second air guide plate 20 in the thickness direction, and the third air guide plate 30 is also provided with a plurality of second air diffusing holes 31 penetrating the third air guide plate 30 in the thickness direction. Preferably, the shape of the first ventilation holes 21 and each of the second ventilation holes 31 may be various, such as a circular shape or an elongated shape, and of course, may be formed in other shapes, such as a square shape, to which the present invention is not limited. And further, the shapes of the plurality of first air vent holes 21 may be different, and the shapes of the plurality of second air vent holes 31 may be different.
Referring to fig. 2 and 3, when the indoor unit 100 of the air conditioner operates in the breeze mode, the first air deflector 10 forms an included angle with the air outlet direction of the air outlet, so as to reflect the air blown out from the air outlet; and the second air deflector 20 and/or the third air deflector 30 extend along the air outlet direction of the air duct. Preferably, the second air guiding plate 20 and/or the third air guiding plate 30 are substantially parallel to the air outlet direction of the air duct. Further, the breeze mode is divided into a first breeze mode and a second breeze mode according to the position state of the second air guide plate 20 and/or the third air guide plate 30;
when the indoor unit 100 of the air conditioner operates in the first breeze mode, the second air deflector 20 and the third air deflector 30 extend along the air outlet direction of the air duct, so that the second air deflector 20 and the third air deflector 30 do not interfere with the air blown out from the air duct. The air blown out from the air duct is reflected by the first air deflector 10 and then bounces back, so that the air blown out from the air conditioner indoor unit 100 is far away, and the air cannot be blown to the active area of the human body below the indoor unit; meanwhile, the wind is diffused into the surrounding air before blowing to the human body, so that the wind quantity felt by the human body is mild.
When the indoor unit 100 of the air conditioner operates in the second breeze mode, the second air deflector 20 or the third air deflector 30 extends along the air outlet direction of the air duct, which means that one of the second air deflector 20 or the first air deflector 10 may have an included angle with the air outlet direction of the air duct; here, taking the direction of the air outlet direction of the second air deflector 20 and the air duct as an example, the third air deflector 30 is parallel to the air outlet direction of the air duct, a part or all of the air blown out from the air duct will pass through the first air dispersing holes 21 on the second air deflector 20 first, the air speed will be diffused and attenuated, and then a part of the attenuated air will be further attenuated after passing through the reflection of the first air deflector 10, so that the air blown to the human body is breeze, and the human body feels comfortable. It will be appreciated that the second breeze mode may also be that the third air deflector 30 is parallel to the air outlet direction of the air duct, and the second air deflector 20 has an included angle with the air outlet direction of the air duct.
In the description of the present invention, the extension of the air deflector along the air outlet direction of the air outlet/air duct means that the position of the air deflector does not affect the air flow in the air duct, i.e. the air deflector does not play a role in stopping the air flow, and the air deflector plays a role in guiding the air flow. The air outlet direction of the air deflector and the air outlet/air channel has an included angle, namely, the position of the air deflector has a certain interference effect on the air of the air outlet/air channel, and the specific interference degree is related to the included angle between the air deflector and the air outlet direction of the air outlet/air channel. Wherein the air guide plate refers to the first air guide plate 10, the second air guide plate 20 and the third air guide plate 30. Meanwhile, in the invention, the extending direction of the air deflector is consistent with the extending direction of the air deflector surface; therefore, in the invention, the limitation on the air deflector is applicable to the air deflector surface.
According to the air conditioning indoor unit 100, the second air deflector 20 and the third air deflector 30 are arranged, and in the breeze mode, an included angle is formed between the first air deflector 10 and the air outlet direction of the air outlet so as to reflect the air blown out from the air outlet, and the second air deflector 20 and/or the third air deflector 30 extend along the air outlet direction of the air channel; at this time, part of wind blown out of the air duct can be directly blown onto the first air deflector 10 and further reflected by the first air deflector 10; part of the air blown out from the air duct passes through the air dispersing holes on the second air guide plate 20 or the third air guide plate 30, and then is blown onto the first air guide plate 10, and is further reflected by the first air guide plate 10, so that the air blown out by the indoor unit 100 of the air conditioner is far away, the air cannot be blown to the movable area of the human body below the indoor unit, and meanwhile, the air is diffused into the surrounding air before being blown to the human body, so that breeze air supply is realized, the air quantity felt by the human body is relatively mild, and the human body comfort is improved.
Based on the above embodiment, when the indoor unit 100 of the air conditioner operates in the breeze mode, the included angle between the first air deflector 10 and the horizontal direction is in the range of-5 ° to 45 °, that is, the first air deflector 10 has a deflection range of 45 ° offset upwards and 5 ° offset downwards along the horizontal direction. Preferably, the first wind deflector 10 is rotated to be nearly horizontal. Here, the horizontal direction is according to the orientation when the air conditioning indoor unit 100 is normally mounted on the wall. When the first air deflector 10 is positioned too much below the horizontal direction, only a small part of air blown out from the air outlet can be interfered, and when the first air deflector 10 is positioned too much above the horizontal direction, the air blown out from the air outlet is reflected towards the top and even towards the installation side of the air conditioner, so that the adjusting speed of the room temperature is slowed down. Therefore, in the breeze mode, the first air deflector 10 is controlled to rotate to be close to the horizontal direction, the adjusting speed of the room temperature is not affected, and meanwhile, the wind speed is effectively reduced, so that breeze supply is realized.
Referring to fig. 4, the indoor unit 100 further has a non-wind-sensation operation mode, when the indoor unit 100 is operated in the non-wind-sensation operation mode, the first air deflector 10 rotates to be close to the horizontal direction, and the second air deflector 20 and the third air deflector 30 rotate to a position having an included angle of 70 ° to 110 ° with the air outlet direction of the air duct, respectively; preferably, the second air deflector 20 and the third air deflector 30 are rotated to a position substantially 90 ° (perpendicular) to the air outlet direction of the duct. After the wind in the air duct passes through the second air dispersing holes 31 of the third air deflector 30, part of the wind flows to the second air deflector 20 and is blown into a room through the first air dispersing holes 21; the other part of the wind blown from the second wind-dispersing holes 31 is blown into the room directly or after being reflected by the first wind deflector 10, thereby reducing the wind speed; most of the wind passes through the third air deflector 30 and the second air deflector 20 in turn, so that the speed of the wind blown out from the air outlet is low, the wind quantity is small, and no wind is generated.
The wind speed blown out from the first and second air holes 21 and 31 can be adjusted by setting the aperture sizes of the first and second air holes 21 and 31. In this embodiment, the aperture of the first air vent 21 is smaller than the aperture of the second air vent 31. The wind pressure borne by the third air deflector 30 can be effectively reduced, the wind blown out by the air duct can rapidly pass through the third air deflector 30, the diffusing capacity of the wind blown out by the air duct is improved, and meanwhile, the aperture of the first air dispersing hole 21 is smaller, so that the purpose of effectively reducing the wind speed is achieved.
Referring to fig. 5, the indoor unit 100 further has a cool air induction mode and a warm air induction mode, when the indoor unit 100 works in the cool air induction mode and the warm air induction mode, the first air deflector 10 is controlled to rotate to a position corresponding to the air outlet direction of the air outlet, and the second air deflector 20 and the third air deflector 30 are both controlled to rotate to a position corresponding to the air outlet direction of the air duct. Therefore, the first air deflector 10, the second air deflector 20 and the third air deflector 30 do not interfere with the air blown out from the air duct, so that the air volume blown out by the air conditioner indoor unit 100 is large, and the temperature in the room can be quickly regulated.
Further, the first air vent 21 and/or the second air vent 31 each have an air inlet and an air outlet; the aperture from the air inlet of the first air-diffusing hole 21 toward the air outlet thereof is gradually increased, and/or the aperture from the air inlet of the second air-diffusing hole 31 toward the air outlet thereof is gradually increased. The first air vent holes 21 and/or the second air vent holes 31 are provided in this way to be more suitable for the wind diffusing characteristics, so that the wind pressure applied to the second air deflector 20 and the third air deflector 30 can be effectively reduced, and the air supply range can be increased.
In one embodiment of the present invention, the second air guiding plate 20 is provided with a plurality of groups of first air diffusing holes 21 distributed at intervals in the length direction, each group of first air diffusing holes 21 comprises a plurality of first air diffusing holes 21 distributed at intervals in the width direction, and the first air diffusing holes 21 of two adjacent groups are distributed in a staggered manner, so that the appearance aesthetic property of the second air guiding plate 20 can be improved, and when the air conditioning indoor unit 100 is in a breeze mode or a windless mode, the maximum range of wind can be diffused to all directions in a room, thereby further reducing the wind speed of the air outlet and realizing the purpose of effectively reducing the wind speed.
Further, the third air deflector 30 is also provided with a plurality of groups of second air dispersing holes 31 which are distributed at intervals in the length direction, each group of second air dispersing holes 31 comprises a plurality of second air dispersing holes 31 which are distributed at intervals in the width direction, and the second air dispersing holes 31 of two adjacent groups are distributed in a staggered manner, so that the appearance aesthetic property of the third air deflector 30 can be improved, and the air supply range can be increased.
Referring to fig. 7, a detailed description is given of a control method of an air conditioning indoor unit 100 according to an embodiment of the present invention, wherein the air conditioning indoor unit 100 is the air conditioning indoor unit 100 according to the above embodiment of the present invention, and an air outlet mode of the air conditioning indoor unit 100 includes a breeze mode, and the breeze mode includes a first breeze mode. It should be noted that, the structure of the indoor unit 100 is described in detail above, and will not be described here again.
The control method of the air conditioner indoor unit 100 according to the embodiment of the invention includes the following steps:
s1: receiving an air-out mode instruction to be set;
s2: when the received air outlet mode instruction is a first breeze mode instruction, the first air deflector 10 is controlled to rotate to a position forming an included angle with the air outlet direction of the air outlet so as to reflect the air blown out from the air outlet; and controls the second air deflector 20 and the third air deflector 30 to rotate to the positions corresponding to the air outlet direction of the air duct.
The instruction for setting the air outlet mode may be issued by a user through remote control or directly operating a key on the panel 43 of the indoor unit 100, which is not limited herein. After the air conditioner is started, when an air outlet mode setting instruction sent by a user is not received, setting is performed according to the preset air outlet mode as the current air outlet mode.
Further, the breeze mode further includes a second breeze mode, and the step S2 further includes:
