The present disclosure proposes an air conditioner and a control method of the air conditioner. The air conditioner can be a split wall-mounted air conditioner, and further can be a single cooling machine or a cooling and heating machine. In the description of the following, an air conditioner with cooling and heating functions is taken as an example for illustration. The air conditioner in the present technical solution includes a breeze mode and a cooling/heating mode.
Referring to Fig. 1, an air conditioner 100 includes a housing 30, a first air guiding plate 10 and a second air guiding plate 20. The housing 30 is provided with an air outlet passage (now shown in the figures) formed in the housing 30 and an air outlet (now shown in the figures) communicated with the air outlet passage and arranged in an outer peripheral wall of the housing 30. The first air guiding plate 10 is rotatably arranged at the air outlet and is connected with the housing 30 by a first rotating shaft 12 of the housing 30. The second air guiding plate 20 is rotatably arranged in the air outlet passage, and is rotatable by a second rotating shaft 22 of the housing. The air conditioner 100 includes a breeze mode, in response to the breeze mode, a part of the air outlet is shielded by the first air guiding plate 10, and the second air guiding plate 20 is extended to a lower side of the air outlet along the air outlet passage.
Specifically, components of the air conditioner 100 are installed in the housing 30, and the housing 30 is used to support and protect internal components while beautifying the appearance of the air conditioner. The housing 30 includes a chassis 31, a face frame (not shown in the figures) and a panel 32. The face frame is provided on the chassis 31, the face frame is open at the front, where the panel 32 is provided. And an air outlet is disposed between the lower end of the panel 32 and the face frame. Specifically, the face frame may be rotatably or detachably arranged on the chassis 31, and the panel 32 may be rotatably or detachably provided on the face frame. It can be understood that the air conditioner 100 further includes swinging blades 50, and the swinging blades 50 are rotatably disposed in the air outlet passage, and controls the air blowing direction from left to right, to realize the air supply in the left and right directions. The air conditioner 100 further includes a fan 40 provided in the housing 30.
In the embodiments of the present disclosure, the housing 30 is further provided with an air outlet passage for air circulation. The air outlet passage forms an air outlet in the outer peripheral wall of the housing 30. When the air conditioner 100 is turned on, the air continuously blows to the indoor space through the air outlet, thereby adjusting the indoor temperature. The first air guiding plate 10 rotates around the first rotating shaft 12 to open or close the air outlet. In the present embodiment, the second air guiding plate 20 is provided with a plurality of second air dispersing holes 21 passing through the second air guiding plate 20. The second air dispersing holes 21 are arranged along the thickness direction of the second air guiding plate 20, and the second air guiding plate 20 can rotate in the air outlet passage along the second rotating shaft 22. With respect to the breezing mode, in response to the breeze mode of the air conditioner 100, a part of the air outlet is shielded by the first air guiding plate 10, and the second air guiding plate 20 is extended to a lower side of the air outlet along the air outlet passage. In a preferred embodiment, the first air guiding plate 10 and the second air guiding plate 20 are substantially mutually perpendicular. The far end of the first air guiding plate 10 in the air out-blowing direction of the air outlet, the far end of the second air guiding plate 20 in the air out-blowing direction of the air outlet, and the first rotating shaft 12 are located substantially on a same plane. The blowing air is blocked by the first air guiding plate 10 and diffused to the surroundings through the second air dispersing holes 21 in the second air guiding plate 20, thereby reducing the air volume and speed of the air outlet. Air blown by the air conditioner 100 is prevented from directly blowing onto the human body, so that the air felt by the human body is rather soft. The air conditioner includes various modes rather than a single mode, and the users demand is met.
Further, when the first air guiding plate 10 closes the air outlet, a side of the first air guiding plate 10 close to an upper side of the air outlet is defined as a first side (not shown in the figures), and a side of the first air guiding plate 10 close to a lower side of the air outlet is defined as a second side (not shown in the figures); the first rotating shaft 12 is extended to the first side to form a first surface, and the first rotating shaft 12 is extended to an edge of the upper side of the air outlet to form a second surface. In which α is an included angle between the first surface and the second surface. That is, the initial position of the first guiding wind corresponds to the initial state when the first air guiding plate completely closes the air outlet. The rotating angle of the first air guiding plate 10 around the first rotating shaft 12 from the initial position is α, when the air conditioner works in the breeze mode, the range of α is no less than 30° and no more than 40°. As such, the air speed coming out of the air outlet passage is weak, the wind volume is not large, and the air is prevented to blow on user's body through the blockage of the first air guiding plate 10. By diffusing to the surroundings along the first air guiding plate 10, the air becomes softer and brings more comfort to the user.
Further, when the air conditioner 100 is in the breeze mode and the range of α is no less than 30° and no more than 40°, the distance M is between the first side and the edge of housing at the upper side of the air outlet, and M is no less than 65mm and no more than 70mm. Alternatively, when the air conditioner 100 is operated in the breeze mode, the distance N is between the second side and the edge of the housing on the lower side of the air outlet, and N is no less than 5mm and no more than 25mm. When the air conditioner works in the breeze mode, the air coming out of the air outlet passage is prone to soften under the action of the first air guiding plate 10. As such, the air from the air conditioner 100 diffusing to the surroundings along the first air guiding plate 10, reduces the air speed and volume out coming from the air outlet, and the user feels soft wind.
Referring to Fig. 2, further, the air conditioner further comprises a cooling/heating mode, and in response to the cooling/heating mode, the first air guiding plate is completely avoided for the air outlet, and the inclined angle α is no less than 65° and no more than 90°. In the embodiments of the present disclosure, the second working mode is a cooling/heating mode, and the first air guiding plate 10 and the second air guiding plate 20 respectively rotate to a position substantially parallel to the air out-blowing direction of the air outlet passage. As such, the side of the first air guiding plate 10 close to the upper side of the air outlet is the first side, and the side of the first air guiding plate 10 close to the lower side of the air outlet is the second side. The first rotating shaft 12 is extended to the first side to form a first surface, the first rotating shaft 12 is extended to end edge of housing at the upper side of the air outlet to form a second surface, the included angle between the first surface and the second surface is α, that is, taking the initial state that the first air guiding plate completely closes the air outlet is taken as an initial position, α is the rotation angle of the first air guiding plate 10 around the first rotating shaft 12 from the initial position. When the rotation angle α of the first air guiding plate 10 is within the range of α being no less than 65° and no more than 90°, the first air guiding plate 10 and the second air guiding plate 20 have less resistance to the blowing air from the air outlet passage, so that the air speed and volume coming out of the air outlet passage are relatively large. The ambient temperature can be changed quickly.
Further, when in the cooling/heating mode, a distance M ranges from 95mm to 110 mm between the first side and the edge of the housing at the upper side of the air outlet. Alternatively, a distance N ranges from 25mm to 45mm between the second side and the edge of the housing at the lower side of the air outlet. In the embodiments of the present disclosure, when the air conditioner 100 is in the cooling/heating mode, and α is no less than 65° and no more than 90°, M ranges from is 95mm to 110mm or N ranges from 25mm to 45mm. It is easy to improve the air speed and volume from the air outlet. At present state, the first air guiding plate 10 has little obstruction to the air outlet of the air conditioner 100, so that the air speed blowing from the air outlet passage is high and the air volume is large, and the temperature in the room is quickly adjusted.
In the embodiments of the present disclosure, the first air guiding plate 10 is provided with air dispersing holes 11 passing through the first air guiding plate 10 in a thickness direction. The length of the diffuser holes 11 in the opening direction is equal to or greater than the thickness of the first air guiding plate 10. The air dispersing holes 11 gradually increase in diameter in a direction from the inner side of the first air guiding plate 10 to the outer side of the first air guiding plate 10. The structure of the air conditioner is simple, enabling the air in the air outlet passage to diffuse to the surroundings from the air dispersing holes 11 of the first air guiding plate 10.
The present disclosure further proposes a control method of the air conditioner 100 which is described above. the air conditioner includes a breeze mode and a cooling/heating mode, in which the air conditioner is switchable between the breeze mode and the cooling/heating mode; the method includes: in response to the breeze mode, shielding a part of an air outlet by a first air guiding plate, and moving the second air guiding plate to a lower side of the air outlet in an air outlet passage, in which the first rotating shaft includes: a first surface extending towards a first side; and a second surface extending towards an edge of an upper side of the air outlet; an included angle α between the first surface and the second surface is no less than 30° and no more than 40°; in response to the cooling/heating mode, completely opening the air outlet by the first air guiding plate, and the inclined angle α is no less than 65° and no more than 90°. The specific structure of the air conditioner 100 refers to the above-mentioned embodiment and will not be described herein.
This is only some embodiments of the present disclosure and is not intended to limit the scope of the present disclosure. Any equivalent structural change made under the concept of the present disclosure using the contents of the present disclosure specification and drawings, or directly/indirectly applied in other related technical fields, shall be included in the protection scope of the present disclosure.
