The present application provides an air conditioner and a method for controlling an air conditioner. The air conditioner may be a split wall type air conditioner, and the air conditioner may be a single refrigerating machine or a refrigerating and heating machine. In the description of the present application, the refrigerating and heating machine is taken as an example for illustration. The working mode of the air conditioner in this solution includes a breezeless mode and a cooling/heating mode.
Referring to FIGS. 1 to 2, an air conditioner 100 includes a housing 30, which includes an air outlet passage (not labeled)formed in the housing 30, and an air outlet (not labeled)formed in an edge of the housing 30 and communicated with the air outlet passage; a first air guiding plate 10 rotatably disposed at the air outlet, and connected with the housing 30 through a first rotating shaft 12 on the housing 30; and a second air guiding plate 20 rotatably disposed in the air outlet passage, and is capable of rotating through a second rotating shaft 22 on the housing 30; where the air conditioner 100 has a breezeless mode, in response to the breezeless mode, at least a part of the air outlet is shielded by the first air guiding plate 10.
Specifically, components of the air conditioner 100 are mounted inside the housing 30, and the housing 30 is further used to beautify the appearance while supporting and protecting the internal components. The housing 30 includes a chassis 31, a face frame (not labeled), and a panel 32. The face frame is disposed on the chassis 31, and a front side of the face frame is open. The panel 32 is disposed on a front side of the face frame. An air outlet is defined between a lower end of the panel 32 and the face frame.
Specifically, the face frame may be rotatably or detachably disposed on the chassis 31, and the panel 32 may be rotatably or detachably disposed on the face frame. It can be understood that the air conditioner 100 further includes a swinging blade 50. The swinging blade 50 is rotatably disposed in the air outlet passage, and controls the air swing in the direction of the left and right sides to realize air supply in the left and right direction. The air conditioner 100 further includes a fan 40 disposed inside the housing 30.
In the embodiment of the present application, an air outlet passage configured for air circulation is further provided inside the housing 30, and an air outlet is formed by the air outlet passage on an edge of the housing 30. The air is blown into an indoor space through the air outlet to adjust the indoor temperature when the air conditioner 100 is turned on. The first air guiding plate 10 is rotated around the first rotating shaft 12 to realize opening or closing of the air outlet. In this embodiment, a plurality of second vent holes 21 passing through the second air guiding plate 20 are provided on the second air guiding plate 20, and the second vent holes 21 are arranged along a thickness direction of the second deflector 20, and the second air guiding plate 20 may rotate in the air outlet passage around the second rotating shaft 22. In response to the breezeless mode, the first air guiding plate 10 is rotated by an angle for shielding at least a part of the air outlet. The air blown by the air conditioner 100 is blocked by the first air guiding plate 10, so that the air volume and the air speed at the air outlet are reduced. The air blown by the air conditioner 100 is prevented from being directly blown on the human body, so that the blowing feeling is softer, which provides various modes, avoids simple blowing feeling, and satisfies customer requirements.
Further, when the first air guiding plate 10 closes the air outlet, the first air guiding plate 10 includes a first side (not labeled) close to an upper wall of the air outlet, and a second side (not labeled) close to a lower wall of the air outlet; where the first rotating shaft 12 includes: a first surface (not labeled) extending towards the first side; and a second surface (not labeled) extending towards an edge of the upper wall of the air outlet, where α is an angle between the first surface and the second surface, and the angle α is no less than 0° and no more than 5°, after the air conditioner 100 is in a breezeless mode. In this state, the air speed of the air coming out from the air outlet passage is lower and the air volume is smaller, the air is blocked by the first air guiding plate 10, and spreads along the first air guiding plate 10 to the surroundings, thereby the air blown by the air conditioner 100 is prevented from being directly blown on the human body, so that the blowing feeling is softer, which is easy for the user to accept and gives the user a comfortable feeling.
Further, in response to the breezeless mode, and the angle α is no less than 0° and no more than 5°, a distance M between the first side and the edge on the upper wall of the air outlet is no less than 0mm and no more than 20mm; or, in response to the breeze mode, a distance N between the second side and an edge of the lower wall of the air outlet is no less than 30 mm and no more than 55 mm. In response to the breezeless mode, the air coming out from the air outlet passage is softened by the action of the first air guiding plate 10. At this time, when the air blown from the air conditioner 100 is diffused to the surroundings along the first air guiding plate 10, the air speed and the air volume coming out from the air outlet are reduced, so that the user does not feel the cold/hot air blown directly from the air outlet of the air conditioner 100.
Referring to FIG. 2, further, the air conditioner 100 further include a cooling/heating mode, in response to the cooling/heating mode, the first air guiding plate 10 is completely open of the air outlet, and the angle α is no less than 65° and no more than 90°. In the embodiment of the present application, the second working mode is a cooling/heating mode, and the first air guiding plate 10 and the second air guiding plate 20 are rotated to be roughly parallel to an air outlet direction of the air outlet passage. At this time, the first air guiding plate 10 includes a first side close to an upper wall of the air outlet, and a second side close to a lower wall of the air outlet; where the first rotating shaft 12 includes a first surface extending towards the first side; and a second surface extending towards an edge of the upper wall of the air outlet. α is an angle between the first surface and the second surface, namely, the first air guiding plate 10 is at an initial position when the first air guiding plate 10 completely closes the air outlet, and the first air guiding plate 10 is rotated around the first rotating shaft 12 at an angle of α from the initial position. When the rotating angle α of the first air guiding plate 10 no less than 65° and no more than 90°, the first air guiding plate 10 and the second air guiding plate 20 have little resistance to the air in the air outlet passage, so that the air speed and the air volume coming out of the air outlet passage are large, which is convenient to change the ambient temperature quickly.
Further, in response to the cooling/heating mode, a distance M between the first side and the edge of the upper wall of the air outlet is no less than 95mm and no more than 110mm. Or, in response to the cooling/heating mode, a range of a distance N between the second side and the edge of the lower wall of the air outlet is no less than 25 mm and no more than 45 mm. In the embodiment of the present application, in response to the cooling/heating mode and the angle α is no less than 65° and no more than 90°, M is no less than 95mm and no more than 110mm, or N is no less than 25mm and no more than 45mm, so that it is easy to increase the air speed and the air volume at the air outlet. At this time, the first air guiding plate 10 has little obstruction to the air coming out of the air conditioner 100, so that the air blown from the air outlet passage has a high air speed and a large air volume, thereby temperature inside the room may be quickly adjusted.
Further, in the embodiment of the present application, the first air guiding plate 10 is provided with a vent hole 11 passing through the first air guiding plate 10 along a thickness direction of the first air guiding plate 10.
Further, a length of the vent hole 11 in an opening direction of the vent hole 11 is equal to or larger than a thickness of the first air guiding plate 10. The vent hole 11 gradually increases in diameter along a direction from an inner side of the first air guiding plate 10 to an outer side of the first air guiding plate 10. The structure is simple and convenient for the air of the air outlet passage to diffuse from the vent hole 11 of the first air guiding plate 10 to the surroundings.
The present application further provides a method for controlling the air conditioner 100, which is described above. The air conditioner 100 includes a breezeless mode and a cooling/heating mode, and the air conditioner 100 is switchable between the breezeless mode and the cooling/heating mode; the method includes: in response to the breezeless mode, a part of an air outlet is shielded by a first air guiding plate 10, and a first rotating shaft 12 includes: a first surface extending towards a first side; and a second surface extending towards an edge of an upper wall of the air outlet; the first side is a side of the first air guiding plate 10 close to the upper wall of the air outlet; and α is an angle between the first surface and the second surface, and the angle α is larger than 40° and no more than 55°; in response to the cooling/heating mode, the air outlet is completely opened by the first air guiding plate 10, and the range of the angle α is no less than 65° and no more than 90°. The specific structure of the air conditioner 100 is referred to the above embodiments, and will not be further described herein.
The foregoing description merely depicts some embodiments of the present application and therefore is not intended to limit the scope of the application. The equivalent structural transformation by using the content of the specification and drawings of the present application, or direct/indirect application in other related technical fields shall all fall in the scope of the application.
