Problems solved by technology
[0003] The existing air conditioner is designed with one air inlet and one air outlet. When cooling, the cold air is affected by gravity and tends to decline. When heating, hot air tends to rise. The air supply direction of the air conditioner can only be adjusted by the air deflector at the air outlet. Up or down, but according to the use effect, the adjustment range of the current air deflector design is still relatively small, which cannot effectively solve the problem of temperature uniformity. The temperature of the feet is 2-3°C, causing discomfort to the human body

Embodiment Construction
[0017] The present invention will be further described below in conjunction with accompanying drawing:
[0018] see figure 1 and figure 2 .
[0019] A cross-flow fan assembly for forward and reverse blowing according to an embodiment of the present invention includes a housing 1, an air duct 2, and a cross-flow vane 3 disposed in the air duct 2, the air duct 2 is disposed in the housing 1, and Both ends of the air duct 2 (both ends along the axis of the cross-flow vane 3 ) are respectively rotatably mounted on the wall of the casing 1 . In the field of machinery, there are many structures to achieve rotational installation, such as installation through shafts and bearings, which will not be described here.
[0020] The present invention can be applied to any electrical appliance that needs air supply, such as air conditioners, air purifiers, etc. Therefore, the above-mentioned shell 1 is a relative concept. If it is applied to an air conditioner, the air conditioner shell ...

The invention discloses a cross-flow fan assembly blowing air forwards and reversely. The cross-flow fan assembly blowing air forwards and reversely comprises an air duct and cross-flow fan blades which are arranged in the air duct, and further comprises a shell; the air duct is arranged in the shell; and the two ends of the air duct are both rotationally installed on the wall of the shell. The position of an air outlet of the air duct is changed by rotating the air duct so that the functions of a draught fan for blowing air forwards and reversely can be achieved, hot air and cold air are blown over the interior of a room more uniformly, the problem that the temperature uniformity of the room is poor is effectively solved, and the comfort feeling of a human body is greatly improved; and besides, the cross-flow fan assembly blowing air forwards and reversely is simple in structure, modification of an existing device is little, manufacturing is easy, and cost is low.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a cross-flow fan assembly for forward and reverse blowing. Background technique [0002] With the development of the economy, household air conditioners and commercial air conditioners are becoming more and more popular, but with people's further requirements on the quality of life, on the basis of air conditioners, the requirements for room temperature uniformity are getting higher and higher. [0003] The existing air conditioner is designed with one air inlet and one air outlet. When cooling, the cold air is affected by gravity and tends to decline. When heating, hot air tends to rise. The air supply direction of the air conditioner can only be adjusted by the air deflector at the air outlet. Up or down, but according to the use effect, the adjustment range of the current air deflector design is still relatively small, which cannot effectively solve the problem of temperature u...
