Background

In the field of electric appliances, there are many kinds of equipment with air outlet function, such as fans, air conditioners, fan heaters, air purifiers and the like, wherein, the column type fans and the air conditioners (indoor units) are widely applied to the household life because of beautiful overall design, small occupied space and better air outlet performance compared with the traditional air outlet equipment. But current column fan and air conditioner also have obvious defect, for example because there is cylindrical shell, the fixed flexibility of inside air-out structure is not high enough, can not realize blowing to a plurality of not equidirectionals or region simultaneously, can only realize blowing in turn to the equidirectional realization through setting up wobbling wind-guiding grid reciprocating pendulum, and this kind of reciprocating pendulum's mode of blowing can't satisfy the user demand of user to the air-out operation at all under many use scenes.

In order to solve the technical problem, various technical schemes appear in the prior art:

for example, chinese patent No. CN201520561551.5 discloses a vertical air conditioner with a swinging blade, in which an air outlet of the air conditioner is provided with an upper and a lower swinging blades, and each swinging blade can swing independently to blow air in different directions. For example, chinese patent No. CN201710425073.9 discloses a vertical indoor unit of an air conditioner, which has three air outlets, and the outlet air has a swing air deflector to blow air in different directions; for another example, CN20152069294.6 discloses a tower fan, the body of which is designed in multi-section mode, each section is provided with an independent driving and air inlet and outlet structure, and each section of the body can rotate independently to blow air in different directions.

The volute air duct wall 210 is provided with an air guide cambered surface 211; the air guide cambered surface 211 is arranged close to a part of cylindrical surface of the cross-flow wind wheel 100; the two ends of the air guide cambered surface 211 are respectively an air inlet side and an air outlet side, and the distance between the air guide cambered surface 211 and the cylindrical surface of the cross-flow wind wheel 100 is gradually increased from the air inlet side to the air outlet side; the volute tongue air duct wall 220 is plate-shaped, one end of the volute tongue air duct wall is close to the cross-flow wind wheel 100, and the other end of the volute tongue air duct wall extends outwards away from the cylindrical surface of the cross-flow wind wheel 100; the air outlet ends of the volute tongue duct wall 220 and the volute duct wall 210 are arranged opposite to each other on two sides of the air outlet 232 and are located on the same side of the cross-flow wind wheel 100.

When the cross-flow wind wheel 100 rotates around the rotation axis of the cross-flow wind wheel in a specific direction, the air is driven to enter the inner side of the volute casing air channel wall 210 through the annular plate 310, the air can continuously flow along the air guide cambered surface 211 and finally flows out from an outlet on the other side of the cross-flow wind wheel 100, and the distance between the air guide cambered surface 211 and the cross-flow wind wheel 100 can reduce noise and further improve air outlet quantity and air outlet speed; therefore, when the cross-flow wind wheel 100 rotates, air can be driven to enter from one side of the cross-flow wind wheel 100 along a specific direction and then flow out from the other side. Compared with the existing air outlet equipment, the air guide structure arranged by the air outlet equipment is integrally designed with the air duct layer structure, the structure is simplified, the air duct layer structure can be accurately matched with each layer for use, the production and installation cost and the difficulty can be greatly reduced, and the air guide structure is completely arranged without being wrapped by the equipment shell 521, so that the equipment shell 521 can be removed by the special design of the air guide structure, the selection range of the inlet and outlet directions of the inlet and outlet air array mechanism 140 in the horizontal direction is larger outside the stable inlet and outlet air path of the air outlet equipment, the control precision of air guide and air outlet can be improved, the application range of the air outlet equipment is further expanded, and the air outlet effect is further improved.
