Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The first embodiment is as follows:

as shown in fig. 1 to 4, in the reversible blowing air conditioner of this embodiment, the air conditioner 1 is installed at a corner in an angular manner, the air conditioner 1 includes a casing 2, an internal air duct 3, a heat exchanger 4, and a pair of cyclones 5, an upper air inlet 20 and a lower air inlet 21 are provided on the casing 2, two ends of the internal air duct 3 are respectively communicated with the upper air inlet 20 and the lower air inlet 21, the heat exchanger 4 and the pair of cyclones 5 are both disposed in the internal air duct 3, the heat exchanger 4 is disposed below the upper air inlet 20, the pair of cyclones 5 is disposed between the heat exchanger 2 and the lower air inlet 21, and a height H = (0.37-0.5) H from the lower air inlet 21 to the ground during installation, where H is a room height.

Referring to fig. 6, in the present embodiment, the heat exchanger 4 is a tilted plate type heat exchanger, and the tilted plate type heat exchanger forms an angle β with the horizontal plane, where β is 40 ° β or more and 70 ° or less, and preferably, β is 55 °.

In the present embodiment, the upper air inlet 20 is disposed on the top surface of the housing 2, the lower air inlet 21 is disposed on the bottom surface of the housing 2, and both the upper air inlet 20 and the lower air inlet 21 can be configured as an air inlet or an air outlet, so as to solve the problem of single air inlet, and during refrigeration, the upper air inlet 20 is an air outlet, and the lower air inlet 21 is an air inlet; when heating, the upper air inlet 20 is an air inlet, and the lower air inlet 21 is an air outlet.

Further, in order to increase the amount of the inlet air or the outlet air, the upper tuyere 20 and the lower tuyere 21 are polygonal or circular in shape.

In this embodiment, the counter-rotating fan 5 includes a first axial fan blade 50 and a second axial fan blade 51 which are oppositely arranged along the axial direction, and the rotating directions of the first axial fan blade 50 and the second axial fan blade 51 are opposite, that is, if the first axial fan blade 50 rotates clockwise, the second axial fan blade 51 rotates counterclockwise; alternatively, the first axial fan 50 may be rotated counterclockwise, and the second axial fan 51 may be rotated clockwise. The first axial fan 50 and the second axial fan 51 are respectively driven by a first motor 53 and a second motor 54, and are used for providing power and controlling the rotation direction and the rotation speed of the first axial fan 50 and the second axial fan 51.

Due to the mutual combination of the heat exchanger 4 and the air opening, the air flow flowing through the upper air opening 20 and the heat exchanger 4 can uniformly flow into the counter-rotating fan 5, so that the performance of the counter-rotating fan 5 is well released, the air quantity can be increased, and the noise can be reduced. When the upper air inlet 20 is an air outlet, the airflow flowing out of the counter-rotating fan 5 can continuously flow into the heat exchanger 4 and the upper air inlet 20 along the axial direction, and in the process, the airflow does not need to be reversed or deviate from the axial direction, so that the resistance of the inner air duct 3 is small.

Referring to fig. 3, in the present embodiment, the housing 2 is cylindrical, and the front panel of the housing 2 is an arc panel.

The working principle of the reversible air supply air conditioner provided by the embodiment is as follows:

referring to fig. 4, during refrigeration, airflow is sucked from a lower air inlet 21, is pressurized by a cyclone fan 5, is sent into a heat exchanger 4 area, is subjected to heat exchange and rectification by the heat exchanger 4, and is blown out from an upper air inlet 20 to form a lower-inlet upper-outlet air supply effect, and is combined with corner hanging type installation of an air conditioner 1, the airflow is blown out from a wall corner on one side of a room and flows to the opposite corner, and flows at the top of the room.

Referring to fig. 5, during heating, the airflow is sucked from the upper air inlet 20, and is subjected to heat exchange and rectification by the heat exchanger 4, and due to the matching combination of the upper air inlet 20 and the heat exchanger 4, the airflow passing through the heat exchanger 4 can uniformly flow into the counter-rotating fan 5 in the axial direction, and then is pressurized by the counter-rotating fan 5 and blown out from the lower air inlet 21. Because the lower air opening 21 is closer to the ground, hot air quickly falls to the ground, is blown out from a wall corner on one side of a room and flows to the opposite angle, air flow flows on the ground of the room, then the hot air floats upwards, good temperature distribution is formed, and the comfort of a human body is greatly improved.

Example two:

referring to fig. 7 and 8, the reversible blowing air conditioner of this embodiment has substantially the same structure as the reversible blowing air conditioner of the first embodiment, and the main difference is that the heat exchanger 4 is a V-shaped heat exchanger, the tip of the V-shaped heat exchanger is disposed toward the direction of the upper air inlet 20,

it should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
