Description

air conditioner

technical field

The invention relates to the field of air conditioners, in particular to an air conditioner with multi-faceted air outlet functions.

Background technique

Generally, air conditioners in the prior art use one cross-flow fan to supply air, and some use two cross-flow fans to supply air. The air conditioner that uses one cross-flow fan to supply air meets the specific structural requirements and heat exchange capacity requirements. , the air conditioner is large in size and has a single air outlet direction; an air conditioner that uses two cross-flow fans to supply air needs to be equipped with dual motors to drive two cross-flow fans respectively, which is costly and will increase the volume of the air conditioner, which is not beautiful . Moreover, it is difficult for existing air conditioners to adopt a cross-flow fan to achieve ultra-thin design and multi-directional air outlet functions under the premise of ensuring performance.

In order to overcome the defects of cross-flow fans, there are also air conditioners that use centrifugal fans instead of cross-flow fans in the prior art. The centrifugal fan is a common component, which is widely used in the field of home appliances, especially in air conditioners, dehumidifiers and other electrical appliances. The centrifugal fan is mainly composed of an impeller and a volute. When the centrifugal fan is working, the impeller rotates at a high speed to suck the air axially, and then discharge it after being compressed by the volute, so as to improve the kinetic energy and static pressure energy of the gas.

For the prior art related to the present invention, please refer to the Chinese Mainland Utility Model Patent No. CN2422569Y announced on March 7, 2001, which discloses an air conditioner with upper and lower air outlets, which includes an air conditioner housing, a heat exchange device, the first centrifugal fan and the second centrifugal fan. There are upper and lower air outlets on the air conditioner casing. The first centrifugal fan includes a first impeller and a first volute sleeved on the outside of the first impeller to guide air flow. The second centrifugal fan includes a second impeller and a second volute sleeved on the outside of the second impeller to guide air flow. The first volute is rotationally symmetrical to the second volute. The first volute has an upper opening communicating with the upper air outlet to form an upper air supply system. The second volute has a lower opening communicating with the lower air outlet to form a lower air supply system. The air conditioner also includes a first motor for driving the first impeller to rotate and a second motor for driving the second impeller to rotate. The upper and lower air supply systems are independently controlled by the first motor and the second motor, which can supply air individually or simultaneously, which is conducive to air convection and improves the speed of adjusting air temperature. However, the structure of this air conditioner uses two motors to drive the two centrifugal fans respectively. The number of motors used increases the cost, and the motor and the centrifugal fan are axially connected, which takes up a lot of space.

Therefore, in view of the above-mentioned technical problems, it is necessary to provide an air conditioner with an improved structure to overcome the above-mentioned defects.
