Being labeled as of each parts in accompanying drawing: 1 shell, 11 air ports, 2 air channels, 21 spiral cases, 22 wind tongues, 211 end caps, 212Teeth, 3 through-flow fan blades, 4 motors, 41 gears.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Referring to Fig. 1 and Fig. 2.
The cross flow fan assembly of the positive-negative air-blowing of one embodiment of the invention, comprises shell 1, air channel 2 and is arranged on air channelThrough-flow fan blade 3 in 2, described air channel 2 is arranged in described shell 1, and the two ends in described air channel 2 are (along through-flow fan blade 3The two ends of axis) be rotatably installed in respectively on described shell 1 wall. The structure that realizes rotation installation in mechanical field is a lot, exampleAs installed by axle and bearing, do not repeat at this.
The present invention can be applied on any electrical equipment that needs air-supply, as air-conditioning, air purifier etc., and therefore above-mentioned shell1 is a relative concept, if be applied on air-conditioning, air conditioner housing is used as above-mentioned shell 1, is applied in airOn clarifier, air purifier is as above-mentioned shell 1 use.
In the present embodiment, in described shell 1, be also provided with the driving mechanism for driving described air channel 2 to rotate, driving mechanism bagDraw together motor 4 and be arranged on the gear 41 on the output shaft of described motor 4, the two ends in described air channel 2 all have end cap 211,Described end cap 211 has circular outer peripheral face, and the outer peripheral face of described end cap 211 is provided with teeth 212, described gear 41 withThe teeth 212 of the outer peripheral face of described end cap 211 are meshed.
The air channel of cross flow fan is generally made up of spiral case 21 and wind tongue 22, and as shown in Figure 2, both form for wind circulationPassage, end cap 211 above-mentioned belongs to a part for spiral case 21, existing end cap is not generally circular, with skyAdjust the clampings such as shell to coordinate, the air channel of existing cross flow fan cannot be rotated. And the present invention becomes to have one by end cover designsCircular outer peripheral face, to form engaged transmission with gear.
Certainly,, in the situation that there is no above-mentioned driving mechanism, also can realize adjustment duct outlet by rotating manuallyObject.
Referring to Fig. 3, when the present invention is applied to cabinet air-conditioner, two air ports 11 are set on shell 1, one of them air port 11Be positioned at the upper end of described shell 1, upward, another air port 11 is positioned at the lower end of described shell 1 in air port, and air port is towards sideFace. According to result of use, the optimum air-supply that heats should be that vertical downward direction blows to floor, blow by the surface on floor,Optimum refrigeration air-supply is vertically upward. In Fig. 3, Fig. 4, arrow represents wind direction.
When air-conditioning heating, referring to Fig. 3, the air outlet in air channel 2 is aimed at the air port, lower end 11 of air conditioner housing 1, is starting like thisAfter through-flow fan blade 3, heat wind and blow from top to bottom, behind ground, then rise gradually gradually;
When air conditioner refrigerating, referring to Fig. 4, starter motor 4, motor 4 drives air channel 2 to rotate by gear 41, makes air channel 2Air outlet aim at the air port, upper end 11 of air conditioner housing 1, starting after through-flow fan blade 3 like this, refrigeration wind blows from bottom to up,Arrive behind top, room, then become to falling gradually.
Can find out, the present invention changes the position of the air outlet in air channel by rotating air channel, realizes that blower fan is forward and reverse to be blown with thisThe function of wind, thus hot blast and cold wind are blown over more equably in room, effectively improve room temperature lack of homogeneityProblem, has strengthened the comfort of human body greatly.
In the present embodiment, referring to Fig. 3, described air channel 2 has an air inlet and an air outlet, the entering of described air channel 2Angle between the line of center, air port, air outlet center and through-flow fan blade 3 axis (in figure shown in a of angle) is 90-150 degree,Be preferably 122 degree. This design meets the air port design of the cabinet air-conditioner of example in figure more, ensures that air-supply is smooth, makesAir-conditioning is heating, and hot blast blows to ground, and when refrigeration, cold wind blows to roof.
Be more than one embodiment of the present invention. It should be pointed out that for the person of ordinary skill of the art, notDepart under the prerequisite of the principle of the invention, can also make some distortion and improvement, all belong to protection scope of the present invention.
