Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 diagram of an air conditioner with dual 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 and a lower air outlet 22. The upper air outlet 21 is provided with a first transverse air deflector 211 which can rotate by a preset rotation angle around the air outlet central line of the indoor unit of the air conditioner; the lower outlet 22 is provided with a longitudinal air deflector 221 and a second transverse air deflector 222, and the longitudinal air deflector 221 can swing around a vertical axis thereof by a preset swing angle.
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. 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 position 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 of 30 ° 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 central line and the indoor size of the air conditioner in the room are determined, the maximum anticlockwise rotation angle theta of the upper air outlet based on the air outlet central line can be calculatedmaxAnd clockwise minimum rotation angle θmin. 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|＞|θminL. If the air outlet center line coincides with the diagonal line of the room and the room is square, | thetamax|＝|θmax|。
As another example of this embodiment, θmaxAnd thetaminThe setting can also be performed by manual setting.

In order to prevent the air from blowing directly onto the wall when the upper duct rotates to the maximum and minimum angles, on one hand, energy loss is caused, and on the other hand, when the air conditioner is in refrigeration or dehumidification operation, the cold air from the air conditioner air outlet causes the wall to be wet and even moldy, and when the air is homogenized, the maximum value of the rotation angle β of the upper duct is equal to
