When the wall-mounted indoor unit works, the wind wheel 2 drives air flow to enter from the air inlet 111, the air flow is sent to the air outlet through the air outlet air duct 1a after heat exchange of the heat exchanger 1, and finally the air flow is blown into a room from the air outlet.
Referring to fig. 2, the first wind deflector 10 is rotatably connected to the housing 100, and the controller controls the first driving device to drive the first wind deflector 10 to rotate so as to open or close the first air outlet; the rotational connection may be a pin joint or a hinge, or a crank structure connection.
Specifically, the first wind deflector 10 is pivotally connected to the housing 100, the first driving device is installed in the housing 100, the first driving device includes a first motor and a first crank, one end of the first crank is connected to the first wind deflector 10, the other end of the first crank is connected to the first motor, the first motor is connected to the controller, and the controller controls the first motor to drive the first crank to rotate so as to drive the first wind deflector 10 to rotate. Obviously, the structure of the first driving device is not limited to this, and the first driving device may further include a first motor and a driving gear connected to the first motor, the pivot shaft of the first wind deflector 10 is mounted with a driven gear meshed with the driving gear, and the first motor drives the driving gear to rotate so as to drive the driven gear to rotate, thereby driving the first wind deflector 10 to rotate.
Referring to fig. 2, the second wind deflector 20 is rotatably connected to the housing 100, and the controller controls the second driving device to drive the second wind deflector 20 to rotate so as to open or close the second air outlet; the rotational connection may be a pin joint or a hinge, or a crank structure connection.
Specifically, the second wind deflector 20 is pivotally connected to the housing 100, the second driving device is installed in the housing 100, the second driving device includes a second motor and a second crank, one end of the second crank is connected to the second wind deflector 20, the other end of the second crank is connected to the first motor, the second motor is connected to the controller, and the controller controls the second motor to drive the second crank to rotate so as to drive the second wind deflector 20 to rotate.

Referring to fig. 2, the controller controls the first motor to drive the first wind deflector 10 to rotate, or controls the second motor to drive the second wind deflector 20 to rotate, so as to switch on or off the first wind deflector 10 and the second wind deflector 20, so that the air outlet path of the wall-mounted indoor unit is changed by switching, and the air outlet effect without wind sense is achieved.
The timing of selectively controlling the driving operations of the first driving device and the second driving device by the controller should be set according to actual needs, and is not particularly limited herein. For example, referring to fig. 3, in the initial stage of cooling, the controller controls the first motor to drive the first wind deflector 10 to rotate so as to open the first air outlet, and at the same time, the controller controls the second motor to drive the second wind deflector 20 to rotate so as to close the second air outlet, so that the air flow of the wall-mounted indoor unit comes out from the first air outlet, and rapid cooling is achieved, which is equivalent to a conventional air outlet mode. Referring to fig. 4, after a period of cooling, the controller controls the first motor to drive the first wind deflector 10 to rotate so as to close the first air outlet, and at the same time, the controller controls the second motor to drive the second wind deflector 20 to rotate so as to open the second air outlet, so that the air flow of the wall-mounted indoor unit comes out from the second air outlet; at this time, if the second air outlet is arranged on the upper side of the first air outlet, the air flow is blown out to a higher position from the second air outlet in a deflection manner and naturally drops in a spraying manner; if the second air outlet is arranged at the lower side of the first air outlet, the air flow is blown out from the second air outlet to the wall hanging of the wall hanging indoor unit in a deflection manner. In the two cases, the air flow is not directly blown to the user, so that the user cannot feel the wind sense, and the wall-mounted indoor unit can realize wind-free air outlet.
According to the technical scheme, the wall-mounted indoor unit is provided with two air outlet paths by arranging the first air outlet and the second air outlet which are communicated with the air outlet duct 1a on the shell 100; the first wind outlet is rotatably provided with a first wind shield 10, the second wind outlet is rotatably provided with a second wind shield 20, the controller is utilized to selectively control the first driving device to drive the first wind shield 10 to rotate so as to open or close the first wind outlet, or control the second driving device to drive the second wind shield 20 to rotate so as to open or close the second wind outlet, so that the switching of the wind outlet path of the wall-mounted indoor unit is realized. If the wall-mounted indoor unit is switched to the state that only the first air outlet is opened, the air flow of the wall-mounted indoor unit is discharged from the first air outlet, so that normal air outlet is realized; when the wall-mounted indoor unit is switched to the state that only the second air outlet is opened, the air flow of the wall-mounted indoor unit is deflected upwards or downwards from the second air outlet and cannot be directly blown to a user, so that the user cannot feel the air flow, and the comfort level of the wall-mounted indoor unit is improved.
Referring to fig. 3 and 4, it is considered that if the second air outlet is disposed above the first air outlet, the air flow blown out from the second air outlet is easy to flow back into the housing 100 from the air inlet 111. Therefore, in this embodiment, in order to avoid the backflow of the air flow of the wall-mounted indoor unit, the second air outlet is disposed at the lower side of the first air outlet, and the front side of the second wind deflector 20 adjacent to the first air outlet is pivotally connected to the housing 100.
Specifically, the second air outlet is disposed at the bottom of the face shell 110, and the front side portion of the second wind deflector 20 adjacent to the first air outlet is pivotally connected to the housing 100, so that when the second wind deflector 20 is opened, the inner surface of the second wind deflector 20 faces the wall of the wall-mounted indoor unit, and the air flow is blocked by the inner surface of the second wind deflector 20 and blows to the wall, so that on one hand, the air flow is prevented from blowing to the user, and on the other hand, the air flow is prevented from flowing back.
Referring to fig. 4, in order to adjust the air flow through the second air outlet, the wall-mounted indoor unit has a volute 120 for forming an air outlet duct 1a, the volute 120 is provided with an air passage 2a communicating the air outlet duct 1a with the second air outlet, and a spoiler 30 is rotatably installed in the air passage 2 a.
Specifically, the volute 120 is located in the housing 100, the volute 120 is configured to form an air outlet duct 1a, the side portion of the spoiler 30, which is closer to the first air outlet, is pivoted to the volute 120, and the opening of the air outlet duct 2a is adjusted by controlling the rotation angle of the spoiler 30, so as to control the air flow through the second air outlet. For example, when the spoiler 30 rotates until the plate surface thereof coincides with the air outlet direction of the air passing channel 2a, the air flow through the second air outlet is large; when the spoiler 30 rotates to an angle between the plate surface and the air outlet direction of the air passage 2a, the air flow passing through the second air outlet is secondary; when the spoiler 30 rotates to a position where the plate surface thereof is perpendicular to the air outlet direction of the air passage 2a, the air flow through the second air outlet is small.
As for the manner of controlling the rotation of the spoiler 30, it may be manually controlled, or may be controlled by a motor drive.
Referring to fig. 5, in order to enhance the windless air-out effect of the second air outlet, the spoiler 30 is provided with a plurality of flow disturbing holes on the surface thereof, and after the air flow sequentially passes through the turbulence holes on the spoiler 30, the air speed of the air flow is reduced and becomes softer, thereby achieving the windless air-out effect. For example, when the first wind deflector 10 is opened, the spoiler 30 is rotated to the inner side of the air outlet channel 1a so as to be perpendicular to the air outlet direction of the air outlet channel 1a or form an included angle, and the air flow of the wall-mounted indoor unit blows into the room through the spoiler holes on the spoiler 30, so that the air outlet of the first air outlet is free from wind. Or when the second wind deflector 20 is opened, the spoiler 30 is rotated to the inner side of the air passage 2a to be perpendicular to the air outlet direction of the air passage or form an included angle, and the air flow of the wall-mounted indoor unit is blown into the room through the spoiler holes on the spoiler 30, so that the second air outlet is enabled to have no air sensing.
Referring to fig. 3, in the present embodiment, a baffle 40 located in the air passage 2a is rotatably installed in the scroll case 120. By adjusting the angle through which the spoiler 30 rotates, the direction of the airflow in the air outlet channel 1a can be adjusted to deviate towards the first air outlet or the second air outlet, so that the airflow through the first air outlet and the second air outlet can be controlled.
Referring to fig. 3, in order to enhance the windless air outlet effect of the first air outlet, an air outlet hole may be formed in the baffle 40. When the air deflector rotates to an angle (right angle or acute angle) between the plate surface of the air deflector and the air outlet direction of the air outlet channel 1a, after the air flow passes through the air dispersing holes on the air deflector, the air speed of the air flow is reduced, so that the air flow speed of the air flow blown to the first air outlet is smaller and softer, and the user cannot feel the flow of the air flow, thereby achieving the effect of no air outlet of the first air outlet.
With continued reference to fig. 3, considering that the temperature difference between the inner side and the outer side of the air passage 2a is relatively large when the air flow passes through the air passage 2a, condensed water is easily generated on the rear wall surface of the volute 120 adjacent to the air passage 2a, it is preferable that an insulation layer 3 is disposed on the inner wall surface of the air passage 2a, and the insulation layer 3 is made of an insulation material, which may be insulation cotton or insulation foam.
Referring to fig. 3, in the same way, considering that the temperature difference between the inner plate surface of the first wind deflector 10 and the outer plate surface thereof is large when the air flow blows out from the first air outlet, condensed water is easily generated on the outer plate surface of the first wind deflector 10, the inner plate surface of the first wind deflector 10 is preferably also provided with the heat insulation layer 3 to avoid the condensed water generated on the outer plate surface of the first wind deflector 10 when the air flow passes through the first air outlet.
Referring to fig. 6 and 7, in another embodiment of the present invention, in order to achieve the adjustable turbulence range of the spoiler 30, based on the above embodiment, the number of the spoiler 30 is plural, and the plurality of spoiler 30 are spliced in sequence along the length direction of the wind channel 2a, and each spoiler 30 is pivotally connected to the volute 120.
Specifically, each spoiler 30 is disposed in a strip shape, and the plurality of spoilers 30 are spliced in sequence along the extending direction of the air-passing channel 2a, and the side portion, adjacent to the first air outlet, of each spoiler 30 is pivoted with the volute 120, so that the air-passing channel 2a is sectionally disturbed by controlling the number of spoilers 30 to achieve the effect of sectionally disturbing the air, thereby realizing sectionally or completely windless air-out of the first air outlet (as shown in fig. 6).
