Further, the driving mechanism for driving the air duct rotation is additionally provided in the shell.
Further, the driving mechanism includes the gear on motor and the output shaft that the motor is arranged in, described
The both ends in air duct all have end cap, and the end cap has circular outer peripheral surface, and the outer peripheral surface of the end cap is equipped with teeth, described
Gear is meshed with the teeth of the outer peripheral surface of the end cap.
Further, there are two air ports, one of air port to be located at the upper end of the shell for tool on the shell, another
Air port is located at the lower end of the shell.
Further, the air duct has an air inlet and an air outlet, the air inlet center in the air duct, outlet air
Angle between mouth center and the line of through-flow fan blade axis is 90-150 degree.
The invention has the benefit that
The present invention changes the position of the air outlet in air duct by rotation air duct, and the function of blower positive-negative air-blowing is realized with this
Can, so that hot wind and cold wind more uniformly be blown in the room, the problem of room temperature uniformity difference is effectively improved, greatly
The big comfort for improving human body；In addition, the configuration of the present invention is simple, small to existing equipment change, it is easy to make, it is at low cost.
Detailed description of the invention

Fig. 2 is the structural schematic diagram in air duct and through-flow fan blade in one embodiment of the invention.
Fig. 3 is the use state diagram that one embodiment of the invention is used for air-conditioning heating air-supply.
Fig. 4 is the use state diagram that one embodiment of the invention is used for air conditioner refrigerating air-supply.
The label of each component in attached drawing are as follows: 1 shell, 11 air ports, 2 air ducts, 21 spiral cases, 22 wind tongues, 211 end caps, 212 teeth
Tooth, 3 through-flow fan blades, 4 motors, 41 gears.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings:
Referring to Fig. 1 and Fig. 2.
The cross flow fan component of the positive-negative air-blowing of one embodiment of the invention, including shell 1, air duct 2 and setting are in wind
Through-flow fan blade 3 in road 2, the air duct 2 is arranged in the shell 1, and the both ends in the air duct 2 are (along 3 axis of through-flow fan blade
Both ends) be rotatably installed on 1 wall of shell respectively.It realizes that there are many structure of rotational installation in machinery field, such as passes through
Axis and bearing are installed, and this will not be repeated here.
The present invention can apply on the electric appliance of any need air-supply, such as air-conditioning, air purifier, therefore above-mentioned outer
Shell 1 is an opposite concept, if applied on air-conditioning, air conditioner housing is used as above-mentioned shell 1, is applied net in air
Change on device, air purifier is used as above-mentioned shell 1.
In the present embodiment, the driving mechanism for driving the air duct 2 to rotate, driving mechanism are additionally provided in the shell 1
Including motor 4 and the gear 41 that is arranged on the output shaft of the motor 4, the both ends in the air duct 2 all have end cap 211,
The end cap 211 has a circular outer peripheral surface, and the outer peripheral surface of the end cap 211 is equipped with teeth 212, the gear 41 with it is described
The teeth 212 of the outer peripheral surface of end cap 211 are meshed.
The air duct of cross flow fan is usually to be made of spiral case 21 and wind tongue 22, as shown in Fig. 2, the two is formed for wind circulation
Channel, end cap 211 above-mentioned belongs to a part of spiral case 21, existing end cap be generally not it is circular, outside air-conditioning
Shell etc. is engaged by clamping, so that the air duct of existing cross flow fan can not rotate.And the present invention by end cover designs at have a circle
Outer peripheral surface, with gear formed engaged transmission.
Certainly, in the case where no above-mentioned driving mechanism, by manually rotate also can be realized adjustment air duct go out
The purpose in air port.
Referring to Fig. 3, when the present invention is applied to cabinet air-conditioner, two air ports 11, one of air port 11 are set on shell 1
Positioned at the upper end of the shell 1, upward, another air port 11 is located at the lower end of the shell 1 in air port, and air port is towards side.Root
According to using effect, optimal heating air-supply should be that vertical downward direction blows to floor, be blown by the surface on floor, optimal
Refrigeration air-supply is vertically upward.Arrow represents wind direction in Fig. 3, Fig. 4.
When air-conditioning heating, referring to Fig. 3, the lower end air port 11 of the air outlet alignment air conditioner housing 1 in air duct 2 is starting in this way
After through-flow fan blade 3, heating wind blows from top to bottom, rises gradually behind ground, then gradually；
When air conditioner refrigerating, referring to fig. 4, start motor 4, motor 4 drives air duct 2 to rotate by gear 41, makes going out for air duct 2
Air port is directed at the upper end air port 11 of air conditioner housing 1, and in this way after starting through-flow fan blade 3, refrigeration wind blows from bottom to up, reaches room
Between behind top, then the drop that gradually becomes.
As can be seen that the present invention changes the position of the air outlet in air duct by rotation air duct, realize that blower is positive and negative with this
To the function of blowing, so that hot wind and cold wind more uniformly be blown in the room, room temperature uniformity is effectively improved
The problem of difference, greatly strengthens the comfort of human body.
In the present embodiment, referring to Fig. 3, the air duct 2 have an air inlet and an air outlet, the air duct 2 into
Angle (in figure shown in a of angle) between the line of 3 axis of air port center, air outlet center and through-flow fan blade is 90-150 degree, preferably
Ground is 122 degree.It is this to design the air port design for being more in line with exemplary cabinet air-conditioner in figure, guarantee that air-supply is smooth, air-conditioning is made to exist
Heating, hot wind blow to ground, and when refrigeration, cold wind blows to roof.
It is above one embodiment of the present invention.It should be pointed out that for those of ordinary skill in the art,
Without departing from the principles of the invention, various modifications and improvements can be made, belongs to protection scope of the present invention.
