Examples

Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present invention provides an air conditioner 100 for regulating and controlling indoor temperature. The air outlet volume can be increased under the condition that the volume of the air conditioner shell is reduced as much as possible, the noise is reduced, the performance of the air conditioner is enhanced, and the attractiveness is improved. In this embodiment, this air conditioner 100 is upper and lower air-out cabinet-type air conditioner, and it can enough carry out the upper end air-out, also can carry out the lower extreme air-out to the effect that the reinforcing was refrigerate or was heated improves user's comfort level.

The air conditioner 100 includes a case 110, a first fan 120, a second fan 130, and a third fan 140. The first fan 120, the second fan 130 and the third fan 140 are all installed in the housing 110, and are sequentially arranged from top to bottom. In this embodiment, the housing 110 is vertically disposed, the first fan 120 is installed at an upper portion of the housing 110, the second fan 130 is installed at a middle portion of the housing 110, and the third fan 140 is installed at a lower portion of the housing 110. The first fan 120 and the second fan 130 are used for air outlet at the upper end of the air conditioner 100, and the third fan 140 is used for air outlet at the lower end of the air conditioner 100.

It is worth noting that the axial directions of the first fan 120 and the second fan 130 are both horizontal directions, the axial direction of the third fan 140 is vertical directions, that is, the first fan 120 and the second fan 130 are both vertically placed, the third fan 140 is horizontally placed, and the placing direction of the third fan 140 is different from the placing direction of the first fan 120 and the second fan 130, so as to save the occupied space, reduce the volume of the housing 110, and improve the aesthetic degree. Specifically, the axial direction of the third fan 140 is arranged in a preset plane, the preset plane is a vertical plane, the axial directions of the first fan 120 and the second fan 130 are both perpendicular to the preset plane, and the projection of the connection line between the central point of the first fan 120 and the central point of the second fan 130 on the preset plane is crossed with the axis of the third fan 140 and is arranged at a preset included angle, so that the first fan 120 and the second fan 130 are arranged in a staggered manner, thereby increasing the air output, reducing the noise, saving the occupied space and reducing the height of the housing 110.

It should be noted that, a central point of the first fan 120 is a central point of a line segment formed by a projection of the first fan 120 on an axis thereof, a central point of the second fan 130 is a central point of a line segment formed by a projection of the second fan 130 on an axis thereof, and since the axes of the first fan 120 and the second fan 130 are both perpendicular to the preset plane, a projection of a connecting line between the central point of the first fan 120 and the central point of the second fan 130 on the preset plane forms a line segment, and the line segment intersects with an axis of the third fan 140 on the preset plane and is arranged at a preset included angle, which is denoted as a for easy understanding.

It should be noted that the range of the preset included angle is 3 degrees to 20 degrees, so as to increase the air output, reduce the noise and ensure the performance of the air conditioner. If the degree of the preset included angle is less than 3 degrees, the distance between the first fan 120 and the second fan 130 in the horizontal direction is small, the overlapped part of the first fan 120 and the second fan 130 is large, the air output is reduced, and the noise is increased; if the degree of the preset included angle is greater than 20 degrees, the first fan 120 and the second fan 130 are too much deviated, which may increase the left-right width of the housing 110 and affect the appearance.
