Hereinafter, a wall-mounted air conditioner indoor unit 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 16, and the wall-mounted air conditioner indoor unit 100 may be used for cooling and heating indoor air.
As shown in fig. 1 to 3 and 6 to 10, the wall-mounted air conditioner indoor unit 100 according to the embodiment of the present invention includes a cabinet 10, a front air guide plate 20, an indoor heat exchanger 60, a main indoor fan 50, and two side fans 40.
As shown in fig. 16, the indoor heat exchanger 60 is disposed in the casing 10, a middle air duct 140 and side air ducts (not shown) disposed at both sides of the middle air duct 140 may be disposed in the casing 10, a front air outlet 110 communicating with the middle air duct 140 may be disposed at a front side of the casing 10, and side air vents communicating with the corresponding side air ducts may be disposed at left and right side walls of the casing 10, respectively. Specifically, a connecting air duct 150 may be further disposed in the casing 10, and the connecting air duct 150 is located between the middle air duct 140 and the side air ducts on the left and right sides, thereby facilitating the circulation of air and air flow. When the wall-mounted air conditioner indoor unit 100 works, indoor air enters the casing 10 to exchange heat with the indoor heat exchanger 60 first, a part of air flow after heat exchange can be discharged from the front air outlet 110 through the middle air duct 140, and another part of air flow after heat exchange can be discharged from the side air vents on the left side and the right side through the side air ducts. Therefore, the wall-mounted air conditioner indoor unit 100 can simultaneously discharge air towards the front and the left and the right sides, so that the air supply efficiency of the wall-mounted air conditioner indoor unit 100 can be improved, and the refrigerating and heating efficiency of the wall-mounted air conditioner indoor unit 100 can be improved.
It will be appreciated that the open/close states of the front air outlet 110 and each side air outlet 120 of the wall-mounted air conditioner indoor unit 100 may be selected according to actual use requirements. For example, when the indoor temperature has been adjusted to the preset temperature, one or more of the front air outlet 110 and the side air outlet 120 may be selectively closed, whereby the power consumption of the wall-mounted air conditioner indoor unit 100 may be reduced without affecting the indoor temperature.
As shown in fig. 6 to 10, the front air deflector 20 is rotatably disposed at the front air outlet 110, and the rotation angle of the front air deflector 20 can be controlled to control the air outlet direction and the air outlet amount of the front air outlet 110. For example, when the wall-mounted air conditioning indoor unit 100 performs a cooling operation, in order to prevent cold air from being directly blown to an indoor user, the front air guide 20 may be adjusted to blow cold air obliquely upward of the wall-mounted air conditioning indoor unit 100, or the front air guide 20 may be adjusted to completely close the front air outlet 110, and the cold air may be discharged through side vents on the left and right sides. Therefore, cold air can slowly circulate in the indoor space in an up-down mode by means of self gravity, so that indoor temperature distribution is more uniform, and use comfort of a user can be improved.
As shown in fig. 15 to 16, the main indoor fan 50 may be disposed in the middle duct 140, the two side fans 40 may be disposed in the two side ducts, respectively, and the direction of the two side fans 40 may be changed so that the side vents are switched between the side air inlets 130 and the side air outlets 120, and when the side vents are the side air inlets 130, the air flow flowing in from the side duct collides with the air flow in the middle duct 140 at a position adjacent to the front air outlet 110. Specifically, the main indoor fan 50 may guide the air flow to flow in the middle duct 140, and the two side fans 40 may guide the air flow to flow in the corresponding side ducts, wherein the rotation direction of the two side fans 40 may be changed. For example, when the two side fans 40 are rotated in the forward direction, the air flow in the casing 10 may be blown out from the side vents, which are the side air outlets 120. When the two side fans 40 are reversed, indoor air may be directed into the cabinet 10 through the side vents, which are the side air inlets 130.
The wall-mounted air conditioning indoor unit 100 may have a normal air outlet mode and a first airless mode. When the wall-mounted air conditioner indoor unit 100 is in the normal air outlet mode, the two side fans 40 rotate forward, the side ventilation openings are the side air outlets 120, and the front air deflector 20 is opened. The wall-mounted air conditioner indoor unit 100 can simultaneously discharge air in the front direction and the left and right directions, and the air supply efficiency of the wall-mounted air conditioner indoor unit 100 can be improved. When the wall-mounted air conditioning indoor unit 100 is in the first airless mode, the two side fans 40 are reversed, the side vents are side air inlets 130, and the front air deflector 20 is opened. At this time, the main indoor fan 50 may guide the air flow after heat exchange to the front air outlet 110, and the two side fans 40 may guide the indoor air flow to the side air channels from the side air inlets 130 on the left and right sides at the same time. The two air streams enter the middle air duct 140 through the connecting air duct 150 and collide with the air stream subjected to heat exchange in the middle air duct 140 at a position adjacent to the front air outlet 110. Thus, the two air streams entering from the side air inlet 130 can be mixed with the air stream with heat exchange completed, so that the temperature of the air stream with heat exchange completed can be more suitable, and the air stream is prevented from being too cold/too hot to cause discomfort of the user. In addition, the two air flows entering from the side air inlet 130 can change the circulation direction of the air flow with heat exchange completion through collision, so that the air flow with heat exchange completion can flow to a plurality of directions of the indoor space, thereby preventing cold air/hot air from directly blowing to indoor users, realizing better windless effect and improving the use comfort of the users.
According to the wall-mounted air conditioner indoor unit 100 of the embodiment of the invention, by arranging the front air outlet 110 and the left and right air outlets 120, the wall-mounted air conditioner indoor unit 100 can blow air in multiple directions of an indoor space, and the refrigerating and heating efficiency of the wall-mounted air conditioner indoor unit can be improved. By arranging the two side fans 40 with variable steering, the temperature of the air flow can be more suitable, the circulation direction of the air flow with heat exchange completed can be changed, thereby realizing better windless effect and improving the use comfort of users.
As shown in fig. 1-2, 7 and 10, according to some embodiments of the present invention, a plurality of first ventilation holes 210 may be provided on the front air guide plate 20, so that a non-wind effect of the wall-mounted air conditioner indoor unit 100 may be enhanced. Specifically, the wall-mounted air conditioner indoor unit 100 may have a second airless mode in which the front air guide plate 20 completely closes the front air outlet 110, and the two side fans 40 are rotated forward. At this time, a part of the heat exchanged air flow is blown out through the left and right side air outlets 120, and another part of the heat exchanged air flow may flow to the indoor space through the plurality of first ventilation holes 210. Since the plurality of first vent holes 210 may be spaced apart from each other, the plurality of first vent holes 210 may have a smaller diameter, and the plurality of first vent holes 210 may function to reduce the circulation speed of the air flow when the air flow passes through the plurality of first vent holes 210. When the air flows out of the plurality of first ventilation holes 210, the circulation speed of the air flow is significantly reduced, thereby achieving a windless effect and improving the comfort level of the user. Alternatively, the front air deflection 20 may be a metal piece to improve the structural strength of the front air deflection 20.
It will be understood, of course, that when the wall-mounted air conditioning indoor unit 100 is in the second non-air-feeling mode, the two side fans 40 may also be reversed, thereby further improving the non-air-feeling effect of the wall-mounted air conditioning indoor unit 100. For example, when the wall-mounted air conditioner indoor unit 100 performs refrigeration, the temperature difference between the temperature of the cold air and the body surface temperature of the user is larger due to the faster air flow rate of the cold air, so that the wall-mounted air conditioner indoor unit 100 can be adjusted to enter the second non-air feeling mode, and meanwhile, the two side fans 40 are reversed, so that the non-air feeling effect of the wall-mounted air conditioner indoor unit 100 can be improved to the greatest extent while the air supply requirement is met, and better use experience can be brought to the user.
As shown in fig. 2 to 5, according to some embodiments of the present invention, a plurality of side air deflectors 30 may be disposed at each side air outlet 120, so that the plurality of side air deflectors 30 may scatter the air flow at the side air outlet 120, and prevent the air flow flowing out from the side air outlet 120 from being directly blown to the user, so that the comfort of the body feeling of the air flow flowing out from the side air outlet 120 may be improved. Alternatively, each of the side air deflectors 30 may be a metal member, so that the structural strength of the side air deflectors 30 may be improved.
In some embodiments of the present invention, the plurality of side air deflectors 30 may be spaced apart in the up-down direction, thereby facilitating the control of the air outlet angle of the air stream. It is of course understood that the distribution of the plurality of side air deflectors 30 is not limited thereto. As shown in fig. 3 to 5, for example, the plurality of side air deflectors 30 may be uniformly spaced in the front-rear direction.
In some embodiments of the present invention, the side air deflector 30 is rotatably provided at the side air outlet 120, so that the air outlet direction and the air outlet amount of the side air outlet 120 can be conveniently adjusted. For example, as shown in fig. 5, the plurality of side air deflectors 30 are uniformly spaced in the front-rear direction, each side air deflector 30 can rotate relative to the air outlet, and the plurality of side air deflectors 30 can change the air outlet direction and the air outlet volume of the side air outlet 120 by changing the rotation angle of the side air deflectors 30. When the plurality of side air deflectors 30 rotate to an angle perpendicular to the airflow flowing direction in the air outlet duct, the side air outlets 120 are completely closed, and when the plurality of side air deflectors 30 rotate to an angle parallel to the airflow flowing direction in the air outlet duct, the side air outlets 120 are completely opened. It will be appreciated that, as shown in fig. 4, the side air deflector 30 may be configured to be fixed relative to the side air outlet 120, so that the side air outlet 120 may blow in one direction, so as to meet specific use requirements.
Alternatively, the opening and closing and opening angles of each side air deflector 30 may be individually controlled, thereby improving the flexibility of use for the user and enabling the wall-mounted air conditioner indoor unit 100 to meet various use demands. For example, when the indoor user concentrates on the right side of the wall-mounted air conditioner indoor unit 100, the side air guide plate 30 at the left air outlet 120 can be controlled to be closed, and the side air guide plate 30 at the right air outlet 120 can be controlled to be opened, so that the wall-mounted air conditioner indoor unit 100 can concentrate on blowing toward the right half part of the indoor space, thereby not only improving the use comfort of the user, but also reducing the energy consumption of the wall-mounted air conditioner indoor unit 100.
According to some embodiments of the present invention, a micro-hole air guide plate may be disposed at each side air outlet 120, and a plurality of side micro-holes may be disposed on the micro-hole air guide plate, thereby improving the windless effect of the wall-mounted air conditioner indoor unit 100. Specifically, when the wall-mounted air conditioner indoor unit 100 is in the non-wind-feeling mode, the micro-hole air guide plate partially or completely closes the side air outlet 120, and when the air flows out of the air outlet duct, the side micro-holes on the micro-hole air guide plate can reduce the circulation speed of the air flow. When the air flow flows out of the side micropores, the circulation speed is obviously reduced, so that the effect of no wind sensation can be realized, and the use comfort of a user is improved.
