Abstract
The utility model provides a cross flow fan of air-conditioning with double directional air supply outlets, which comprises a rotating shaft, a middle wind wheel, and a leaf. The utility model is characterized in that: the cross flow fan is separated into two or more sections at least along the shaft, and the rotation directions of leaves which are arranged on the neighboring sections are opposite. An air-conditioning with double directional air supply outlets, which comprises a shell with double directional air supply outlets on the upper side and the lower side of which are both provided with air supply gates and a cross flow fan, is characterized in that: the cross flow fan is separated into two or more sections at least along the shaft, and the rotation directions of leaves which are arranged on the neighboring sections are opposite. When the cross flow fan rotates forwards (or backwards), leaves of odd sections rotates to supply air. And when the cross flow fan rotates backwards (or forwards), leaves of even sections rotates to supply air. The wall hanging air-conditioning with a cross flow fan which has the function of double directional air supply upwards and downwards can realize the best air supply type of cool air supply upwards and warm air supply downwards. The utility model is simple in structure, convenient in manufacture, low in cost. Further, the air-conditioning volume is not increased.
Description
Technical field
The utility model belongs to the improvement of air conditioner axial-flow fan, is a kind of two-way air-out air conditioner axial-flow fan specifically.
Background technique
In existing air conditioner, occur for improving air-supply effect air conditioner existing two-way or the four-way air-out.But this class air conditioner must the plural fan of configuration.Both increase the fabricating cost of transmission part and air conditioner, strengthened the air conditioner volume again.And an axial-flow fan of existing wall-hanging air conditioner can not be realized two-way air-supply.
Summary of the invention
The utility model is at the deficiencies in the prior art, and a kind of air conditioner axial-flow fan is provided, and only adopts an axial-flow fan just can realize the two-way air-out of air conditioner.
Technical solutions of the utility model are: a kind of two-way air-out air conditioner axial-flow fan, comprise rotating shaft, middle wind wheel and blade, and it is characterized in that described axial-flow fan is divided into more than two sections vertically at least, and the blade sense of rotation that two neighboring sections is provided with is opposite.
On the described axial-flow fan in two the blade between the wind wheel be one section, the blade sense of rotation of its odd number section is consistent with the positive veer of axial-flow fan, the blade sense of rotation of its even number section is consistent with the axial-flow fan reverse directions.
A kind of two-way air-out air conditioner, the housing and the axial-flow fan that comprise the two-way air-out that is equipped with outlet grid up and down, it is characterized in that described axial-flow fan is one, axial-flow fan is divided into more than two sections vertically at least, and the blade sense of rotation that two neighboring sections is provided with is opposite.
Described two-way air-out air conditioner, on its axial-flow fan in two the blade between the wind wheel be one section, the blade sense of rotation of its odd number section is consistent with the positive veer of axial-flow fan, the blade sense of rotation of its even number section is consistent with the axial-flow fan reverse directions.
The utility model compared with prior art has many advantages and good effect:
Because of axial-flow fan of the present utility model is divided into more than two sections vertically at least, and the blade sense of rotation that two neighboring sections is provided with is opposite.When axial-flow fan forward (or oppositely) rotation, the blade rotation air-out of its odd number section; When axial-flow fan reverse (or forward) rotation, the blade rotation air-out of its even number section.So, only adopt the wall-hanging air conditioner of an axial-flow fan just can have up or down two-way air-out function, can realize upwards blowing a cold wind over, downwards the best air supply mode of blowing hot-air.It is simple in structure, and is easy to make, and cost is lower, and does not strengthen the air conditioner volume substantially.
Description of drawings
Fig. 1 is the plan view of the utility model axial-flow fan;
Fig. 2 is that Figure 1A-A is to sectional drawing;
Fig. 3 is that Figure 1B-B is to sectional drawing;
The schematic representation that Fig. 4 upwards blows a cold wind over for the utility model wall-hanging air conditioner;
Fig. 5 is the schematic representation of the downward blowing hot-air of the utility model wall-hanging air conditioner.
Embodiment
Among the figure, 1, axial-flow fan; 2, blade; 3, axial-flow fan rotating shaft; 4, middle wind wheel; 5 housings.
Referring to Fig. 1-Fig. 3, a kind of wall-hanging air conditioner axial-flow fan 1 of two-way air-out, blade 2 between wind wheel 4 is as one section in two on it, and blade 2 sense of rotation of its odd number section are consistent with axial-flow fan 1 positive veer, and blade 2 sense of rotation of its even number section are consistent with axial-flow fan 1 reverse directions.
Referring to Fig. 4, Fig. 5, a kind of two-way air conditioner that goes out only disposes a two-way air-out wind axial-flow fan 1, and when axial-flow fan 1 was rotated in the forward, the blade 2 rotation air-out of its odd number section just can upwards be blown a cold wind over by the outlet grids above the housing 5; When axial-flow fan 1 counterrotating, the blade 2 rotation air-out of its even number section just can be by the downward blowing hot-air of outlet grid below the housing 5.Thereby the wall-hanging air conditioner of having realized only adopting an axial-flow fan 1 just can be realized the function of two-way air-out.
Claims (4)
