In the known air conditioner, after pressure fan 20 starts, room air is drawn to the inside of casing 50, and after heating or freeze by heat exchanger 30, is discharged to the outside by exhaust outlet 52.The wind direction that is discharged to the air outside air-out by exhaust outlet 52 is subjected to the control of the shutter 60 on the exhaust outlet 52.

In the air-conditioner operation process, when motor 70 starts, the angle that rotating shaft 72 rotating driveshafts 80 are certain, and the layout angle of shutter 60` also changes along with the rotation of driving shaft 80.

In the driving shaft 80 of the air conditioner shutter 60` of known technology, the molding structure 84 of axis hole 82 is subjected to can being damaged when extraneous impact or motor 70 and shutter 60` are sagging, and at this moment motor 70 will rotate shutter 60`.

Summary of the invention

In order to solve the problem that above-mentioned technology exists, the invention provides a kind of shutter protection structure of air conditioner, it can prevent the damage and the malfunction of shutter.

To achieve these goals, the technical solution used in the present invention is: the present invention includes: rotating being arranged on the exhaust outlet of discharging air, and be equipped with the shutter of the driving shaft that is formed with axis hole; The motor that rotating shaft combines with the axis hole of driving shaft; The protective material that is arranged at the driving shaft periphery constitutes.

Above-mentioned protective material adopts the hollow type material that surrounds the driving shaft periphery, and is provided with the outstanding epicostal flange of connection that is fixed on the shutter that forms.

The invention has the beneficial effects as follows: the utilization of air conditioner shutter of the present invention protection structure is arranged on the intensity that protective material on the driving shaft is strengthened driving shaft and axis hole molding structure, can prevent that driving shaft from damaging.Protective material adopts the hollow type material that surrounds the driving shaft periphery; and the outstanding epicostal flange of connection that is fixed on the shutter that forms; when driving shaft is subjected to external force on the radial direction; flange on the protective material can be fixed on and connect on the rib, prevents the damage at position between driving shaft and the connection rib.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 4 is the amplification oblique drawing of the partial cross section of indoor machine of air conditioner of the present invention, Fig. 5 is the exploded perspective view of shutter of the present invention and motor, and Fig. 6 is the sectional drawing of shutter of the present invention and motor syndeton.In an embodiment of the present invention, the bottom of casing 50 is provided with the inlet scoop, and the top is provided with exhaust outlet 52, and the inside of casing 50 is provided with heat exchanger and pressure fan.

Several shutters 60 of the direction of the air of adjusting output are set on exhaust outlet 52, drive the motor 70 that shutter 60 rotates and around exhaust outlet 52, be provided with.

Shutter 60 comprises: be vertically set on the exhaust outlet 52 and swing, the perpendicular shutter of the outbound course of the air of control left and right directions and being arranged on the exhaust outlet 52 stirs up and down, and several horizontal shutters of the outbound course of the air of control above-below direction constitute.

Shutter 60 is by stirring simultaneously with each shutter 60 vertical shutter connecting rod that link to each other, if therefore some shutters 60 wherein stir, then other shutter 60 all can and then stir.

Shutter 60 adopts plate structure, at the outstanding connection rib bone 61 that forms in its one side both sides, and at the bolster 62 that connects on the rib 61 towards the relative pivot that is provided as shutter 60.

Some shutter 60` in the shutter 60 are connected with the motor 70 that is arranged on exhaust outlet 52 next doors, when motor 70 starts, with other shutter 60 rotations.

Vertical stand-up connects rib 65 on the one side both sides of the shutter 60` that is connected with motor 70, and connected the rotating shaft 72 of motor 70 on wherein some, and the outstanding driving shaft 80 that forms as shutter 60` pivot, and another connect on rib 65 outstanding form with driving shaft 80 towards relative bolster 68, support shutter 60`.

Rotating shaft 72 in order to insert motor 70 on the driving shaft 80 is provided with axis hole 82 in the longitudinal direction, and in order to make axis hole 82 parallel with shutter 60, makes it and to be connected rib 65 vertical.

Axis hole molding structure 84 that forms axis hole 82 and the protective material 90 of protecting driving shaft 80 are set on the periphery of driving shaft 80.

Protective material 90 adopts hollow, inserts the periphery of driving shaft 80 in the longitudinal direction, surrounds driving shaft 80 thus, and connects on the rib 65 tab-like one-tenth flange 92 for an end is fixed on.

Protective material 90 should adopt in light weight, the metal material that intensity is high.The structure that constitutes four jiaos of type frameworks 97 is a hollow, and is arranged at casing 50 front upper parts, constitutes the diffuser of exhaust outlet 54, forms to support shutter 60 the support holes 97a that the bolster 62,68 of 60` and protective material 90 rotate on its both sides or upper and lower sides.

As above the effect of the present invention of Gou Chenging is as follows.At first, in the operation of air-conditioner process, after motor 70 started, rotating shaft 72 rotated a certain angle driving shaft 80, and shutter 60` is that the center change is provided with angle with driving shaft 80 and bolster 68.Be connected shutter 60` on the motor 70 when stirring, the shutter 60 that connects with motor 70 is not stirring with the shutter 60` that is connected on the motor 70 under the effect of shutter connecting rod.

Protective material 90, rotates with driving shaft 80 when 60` stirs at shutter 60; prevent the wearing and tearing of the outer surface of driving shaft 80; and when external force or impact force action, supporting driving shaft 80 and axis hole molding structure 84 prevent the damage of driving shaft 80 bendings or axis hole molding structure 84 thus.

When flange 92 is subjected to external force on the radial direction or impulsive force at driving shaft 80, is fixed on and connects on the rib 65, prevent driving shaft 80 and the position that connects between the rib 65 is damaged.

Main contents of the present invention are not limited to described embodiment and key diagram; within the technical scope under the present invention, can carry out various variations to the shape or the material of protective material; and go for installing in all air conditioners of shutter, protective material can also be arranged on the periphery of bolster.
