Detailed ways

The automatic cleaning filter device shown in Figure 1 includes a filter screen body 1, which is fixedly installed at the air inlet of the air conditioner indoor unit body by means of a fixed connection structure, wherein: when the filter screen body 1 is perpendicular to the horizontal plane Both sides of the guide rail 2 are respectively provided with runners 3, and a cleaner is connected between the runners 3. The motor is installed on the cleaner, and at least one runner 3 is connected with the shaft of the motor. The lower end of the net body 1 is provided with a dust box 7 . In order to realize the cleaning function, there may be two aforementioned motors, which are respectively installed at both ends of the cleaner with the crankshaft facing outwards. The aforesaid runner 3 and the guide rail 2 are mated and connected. Meanwhile, the length of the cleaner is the same as the width of the filter body 1 ; or the length of the cleaner is greater than the width of the filter body 1 . In order to realize that the cleaner does not need to damage the filter screen when cleaning the dust, the aforementioned cleaner is a brush 6 whose bristles are in close contact with the filter screen. In order to facilitate the user to observe the situation of dust accumulation in the box, the dust collecting box 7 is made of transparent material, which can be easily removed from the installation position and emptied in time.

Its assembling process is as follows: firstly, the machine shafts of the two motors face outwards, and then they are installed on the two ends of the hair brush 6 respectively. At the same time, the runners 3 are installed at the two ends of the hairbrush 6 respectively. And allow the machine shaft of motor to be connected with runner 3, so that runner 3 provides power. Subsequently, the runners 3 are installed on the guide rails 2 provided on both sides of the filter body 1 according to the engagement mode. It is because of the meshing connection that the guide rail 2 limits the displacement of the runner 3 and also limits the position of the brush 6 connected thereon, ensuring that the brush 6 is in close contact with the filter. Then, the dust box 7 is placed on the lower end of the filter body 1, and the installation of the automatic cleaning filter device is completed. And, in order to realize that the brush 6 can move up and down after the runner 3 cooperates with the guide rail 2, the rotation directions of the crankshafts of the two motors are opposite when they work, that is, they are divided into an up motor 4 and a down motor 5.

During use, after the air conditioner indoor unit body receives the cleaning instruction sent by the user, since the default standby position of the hair brush 6 is in the lower half of the filter body 1, the upward motor 4 starts to work at first. Furthermore, after the upward motor 4 works, the crankshaft drives the mounted runner 3 to start rotating, so that the whole brush 6 along the track of the filter screen body 1 starts to move upward. By closely contacting the brush 6 with the filter screen body 1 , the dust adhering to the surface of the filter screen body 1 is brushed off and falls into the dust collecting box 7 . When the brush 6 moves to the top of the filter body 1, the down motor 5 starts to work, that is to say, the down motor 5 drives another runner 3 to rotate, which makes the brush 6 go down along the guide rail 2 by means of meshing connection. brush, and clean the filter body 1 again. Of course, the automatic cleaning filter device can also be activated with the operation of the air conditioner to realize the automatic cleaning function of the filter screen.

A motor is adopted, and the steering of the motor shaft is forward and reverse bidirectional alternate rotation, which can also realize the up and down movement of the hair brush 6 on the filter screen body 1 . If the length of the brush 6 is greater than the width of the filter body 1, a good cleaning effect can also be achieved.

By using the automatic cleaning filter device, the air conditioner can automatically clean the filter screen according to the needs, thereby avoiding the accumulation of dust and bacteria on the filter screen, ensuring the cleanliness of the filter screen, and reducing the operating noise and noise of the air conditioner. power consumption, which greatly facilitates the use of users.

Of course, the above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. In addition to the above-mentioned embodiments, the utility model can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
