DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.
FIG. 1 is a perspective view showing a state in which an air conditioner according to the present invention has a filter pulled out to the front, and FIG. 2 is a cross-sectional view of a main body. FIG. 3 is a perspective view showing the filter, and FIG. 4 is a graph showing the relationship between the addition rate of the additive to the filter and the friction coefficient.
As shown in FIGS. 1 and 2, the air conditioner according to the present invention includes a base 1 installed on a wall surface, and an upper portion mounted on an upper front portion of the base 1 and having a suction port 4 extending from the front end to the vicinity of the rear end. The main body is comprised by the panel 3 and the lower panel 2 in which the blower outlet 5 provided with the several wind direction deflection | deviation plate 5a was mounted | worn by the lower front part.
[0010]
The air passage connecting the suction port 4 and the blowout port 5 is composed of a front heat exchanger 6a inclined backward and a rear heat exchanger 6b inclined forward and formed in an inverted V shape. 6 and a blower fan 7 that sends out the air heat-exchanged by the heat exchanger 6 into the room, and drops below the front heat exchanger 6a and the rear heat exchanger 6b. A dew tray 8 for receiving condensed water is provided.
[0011]
A filter 10 that adsorbs dust contained in the sucked air is slidably mounted on the back surface of the suction port 4, and a passage port through which the filter 10 passes is provided in front of the body. A dust box 11 is provided, and a drive unit 12 for pulling out the filter 10 to the front side of the main body and automatically storing it in the main body is provided below the dust box 11. A slit-shaped insertion / removal opening 9 is formed between the front end of the upper panel 3 and the front end of the lower panel 2 so that the filter 10 can be inserted into and removed from the front surface of the main body.
[0012]
As shown in the perspective view from the back side of FIG. 3, the filter 10 is formed with a rail in the center along the sliding direction, and rails 10d guided by guide rails formed on the main body on both side edges. It consists of a frame 10a made of a soft resin material and a pair of left and right mesh portions 10b molded integrally in the frame 10a. The formed rack 10c is formed.
[0013]
As shown in FIG. 4, the dust box 11 is composed of an upper box 11a and a lower box 11b which are divided into upper and lower parts, and a slit-like passage opening through which the filter 10 passes at the front end and the rear end of the joint. Is formed. The upper box 11a is provided with a brush 13 and a brush 14 supported by a base, and the lower box 11b is provided with a brush 15 supported by the base. A drive device 12 is provided below the dust box 11. The drive device 12 is linked to a drive motor 16 having a pinion gear fitted to a rotating shaft, and is linked to the drive motor 16. It is composed of a gear 17 that engages.
[0014]
When the drive motor 16 is started, the gear 17 linked to the drive motor 16 is rotationally driven, and the filter 10 is moved forward by the rack 10c engaged with the gear 17. When the filter 10 moves, the dust adhering to the surface of the filter 10 is scraped by coming into contact with the brush 13 and the brushes 14 and 15 and stored in the dust box 11.
[0015]
The filter 10 is made of synthetic resin polypropylene as a base material, and the frame body 10a, the mesh portion 10b, and the rack 10c are integrally formed by resin molding. Silicone additives that reduce the coefficient of friction are added during resin molding.
[0016]
As shown in the graph of FIG. 5, when the addition ratio of the silicon-based additive and the friction coefficient of the added base material exceed 5%, the friction coefficient starts from around 0.2 μm. It can be seen that the value rapidly decreases in the range of 0.15 μm. However, when the addition ratio in weight percent is 15% or more, there is a possibility of affecting the characteristics of polypropylene as a base material. In this embodiment, the practical addition ratio is in the range of 5% to 15%.
[0017]
Friction between the brushes 13, 14 and 15 and the surface thereof when the filter 10 is moved and cleaned by the drive device 12 by adding an additive having lubricity to the base material constituting the filter 10. In addition to reducing the force, the frictional force with the guide rail in the main body can be reduced to perform a smooth filter cleaning operation.
[0018]
【The invention's effect】
As described above, according to the present invention, an additive that is excellent in lubricity and reduces the coefficient of friction is added to the base material constituting the filter at the time of resin molding. The air conditioner can reduce the frictional force between the provided brush and the surface of the filter and reduce the frictional force with the guide rail in the main body to perform a smooth filter cleaning operation.
