Problems solved by technology
[0002] Existing wind rotor air ducts, including centrifugal rotor air ducts and cross-flow rotor air ducts, generally adopt a single-sided air outlet method, and cannot perform multi-directional air outlet
Existing ways of using multi-faceted air outlets, one is to use axial-flow fan blades to deflect the axial wind through a certain curved wall surface at the top, so that the air is released from the four sides in a circumferential direction. The multi-faceted air outlet effect is poor, because The loss caused by the air duct is very large, and the air volume and wind speed are very small
The other is the double-sided air outlet of the cross-flow air duct. The principle is to divide the wind wheel into several sections, and arrange the volute tongue and the volute case in a dislocation manner to realize multi-directional air outlet. The disadvantage is that the outlet positions are not on the same horizontal plane, and the outlet There is a corresponding dislocation of the wind position, which makes the wind effect not good

The invention discloses a cross-flow fan, a fan and a heater with the same. The cross-flow fan includes: a volute and a cross-flow rotor. An air inlet and at least two air outlets are arranged on the same cross section of the volute, and the air inlet and at least two air outlets are distributed along the circumference of the volute at intervals. The cross-flow wind wheel is arranged in the volute to suck the air flow into the volute from the air inlet and blow out the air flow in the volute from at least two air outlets. According to the cross-flow fan of the embodiment of the present invention, since the volute is provided with air inlets and at least two air outlets distributed along the circumferential direction of the volute, multi-directional air supply can be realized, and because at least two air outlets on the volute The two air outlets are located on the same cross section, that is to say, the multi-directional air supply is not realized by dislocation, so as to ensure good air outlet performance and large wind speed and air volume.
Description
technical field [0001] The invention relates to the technical field of household appliance construction, in particular to a cross-flow fan and a fan and a heater having the same. Background technique [0002] Existing wind rotor air ducts, including centrifugal wind rotor air ducts and cross-flow rotor air ducts, generally adopt a single-sided air outlet mode, and cannot perform multi-directional air outlet. Existing ways of using multi-faceted air outlets, one is to use axial-flow fan blades to deflect the axial wind through a certain curved wall surface at the top, so that the air is released from the four sides in a circumferential direction. The multi-faceted air outlet effect is poor, because The loss caused by the air duct is very large, and the air volume and wind speed are very small. The other is the double-sided air outlet of the cross-flow air duct. The principle is to divide the wind wheel into several sections, and arrange the volute tongue and the volute case ...
