All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, the descriptions of the directions of up, down, left, right, front, and back, and the clockwise and counterclockwise directions are all defined as shown in the drawings of the specification, and when the placement manner of the air conditioner is changed, the descriptions of the corresponding directions, and the clockwise and counterclockwise directions will also be changed according to the change of the placement manner, and the description of the present invention is not repeated herein.
Fig. 1 is a schematic structural view of an air conditioner with double air outlets according to an embodiment of the present invention. The embodiment of the invention provides an air conditioner with double air outlets, which comprises: an air conditioner case 1, an air blowing device 2 and a controller 3.
The air supply device 2 is arranged in the air conditioner casing 1. The air supply device 2 includes an upper air outlet 21, a lower air outlet 22, a first air outlet motor 23, and a second air outlet motor 24. The upper air outlet 21 is provided with a first transverse air deflector 211; the upper air outlet 21 can rotate by a preset rotation angle around the air outlet central line of the indoor unit of the air conditioner; the lower air outlet 22 is provided with a longitudinal air deflector 221 and a second transverse air deflector 222; the longitudinal air deflector 221 can swing around the vertical axis thereof by a preset swing angle; the first transverse air guiding plate 211 and the second transverse air guiding plate 222 can swing up and down by a preset swing angle around the horizontal direction.
Specifically, the upper and lower air outlets 21 and 22 of the air conditioner are respectively connected to corresponding air outlets, a centrifugal fan is disposed in the upper air outlet corresponding to the upper air outlet 21, and a cross-flow fan is disposed in the lower air outlet corresponding to the lower air outlet 22, so as to realize an air outlet function of the air conditioner. The first outlet motor 23 may be a centrifugal fan motor, and the second outlet motor 24 may be a cross-flow fan motor. In the embodiment of the invention, the centrifugal fan arranged in the upper air outlet channel has the characteristic of long air supply distance, and the cross-flow fan arranged in the lower air outlet channel has the characteristics of short air supply distance, low noise and low motor power. The multi-dimensional air outlet form is formed by combining the upper air outlet and the lower air outlet, a plurality of special airflow organizations can be realized, and various user comfort experiences are built.
Further, the upper air outlet 21 may rotate around an indoor unit air outlet center line of the air conditioner by a preset rotation angle, and the rotation angle range of the upper air outlet 21 is set according to an indoor installation position of the air conditioner. For example, when the air conditioner is installed at a corner position of a room, the rotation angle range of the upper outlet 21 is 90 °; when the air conditioner is installed at the middle part of an indoor wall, the rotating angle range of the upper air outlet 21 is 180 degrees, so that indoor comprehensive large-angle air supply is realized.
Fig. 2 is a schematic view of the rotation angle of the upper outlet in the top view according to the embodiment of the present invention. In this embodiment, the upper air outlet 21 is located at an initial position coinciding with the front center of the air conditioner, the front center is set to coincide with the air outlet center line, and the rotation angle of the initial position is 0 °. When the air conditioner is in a shutdown state or a standby state, the rotation angle of the upper air outlet 21 is 0 °. When the air conditioner is in an operating state, the upper air outlet 21 can rotate counterclockwise or clockwise around the air outlet center line of the air conditioner relative to the initial position, the counterclockwise rotation angle is set to be greater than 0 degrees, and the clockwise rotation angle is set to be less than 0 degrees.
For example, the rotation angle of the upper outlet 21 is-30 °, which means that the upper outlet 21 rotates clockwise 30 ° around the air outlet centerline of the air conditioner relative to the initial position; the rotation angle of the upper outlet 21 is 30 °, which means that the upper outlet 21 is rotated 30 ° counterclockwise around the outlet centerline of the air conditioner with respect to the initial position.
Preferably, a TFT intelligent touch color display screen is arranged on the air conditioner, and a user can set related parameters of the air conditioner through the display screen. For example, first, a top plan view of a current room is visually displayed to a user by inputting parameters such as a length, a width, and a graphic layout of the room into the display screen, and then generating a room graphic, a length scale, a width scale, and a display scale. Second, the relative position of the window or the balcony is set according to the top plan view, which facilitates the user to determine the installation position of the air conditioner. And thirdly, setting the placing position and the orientation of the air conditioner, and previewing the placing position by dragging the air conditioner marker in the top plan view by a user to preliminarily determine the orientation and the air outlet central line of the air conditioner. Fourthly, after the actual position of the air conditioner is determined, the user can set an air outlet central line. The air outlet central line can be not the central line or the central axis of a room, and can be set by combining the indoor size or furniture placement and the main movement range of a user.
After the actual position, the outlet center line and the indoor size of the air conditioner are determined, the maximum counterclockwise rotation angle θ of the upper outlet 21 in fig. 2 based on the outlet center line can be calculated max And clockwise minimum rotation angle θ min . The counterclockwise rotation angle is set to be a positive number, and the clockwise rotation angle is set to be a negative number.
In the example of fig. 2, since the air outlet center line coincides with the diagonal line of the room and the room is rectangular, the magnitude of the angle is compared with | θ | max |＞|θ min L. If the air outlet center line coincides with the diagonal line of the room and the room is square, | theta max |＝|θ max |。
As another example of this embodiment, θ max And theta min The setting can also be performed by manual setting.
In this embodiment, the display screen may also be used for the user to set the table. When the user opens the restaurant wind function for the first time, the actual position of the dining table in the guest restaurant needs to be set through the display screen. The table may be located, for example, by dragging the table identifier to the top plan view. After the position is confirmed, the size of the dining table marker can be adjusted on the display screen through the scale, finally, according to the relative positions of the scale, the air conditioner and the dining table, the distance parameter rho (unit cm) between the center of the dining table and the air conditioner is calculated, the included angle parameter alpha (unit degree) between the center of the dining table and the air conditioner and the air outlet center line is stored, the distance parameter and the included angle parameter are stored, and when the wind function of the dining room is started next time, the two parameters are directly called. For details, see fig. 3, where fig. 3a is the left side of the air outlet center line of the dining table, and fig. 3b is the right side of the air outlet center line of the dining table, that is, the distance parameter and the included angle parameter are obtained by calculation according to the actual position of the air conditioner, the actual position of the dining table, the air outlet center line, and the indoor size.
