The suction port 2 in the upper part of the front surface is opened and closed by an opening / closing body 7 made of a decorative plate, and a driving device for driving the opening / closing body 7 includes a driving motor 8 and a driving shaft 8a of the driving motor 8.
And a drive link 9 having both ends connected to the opening / closing body 7
A biasing means for biasing the lower end of the opening / closing body 7 toward the front panel 1a, and a lower end of the drive link 9 extending along the lower end of the drive link 9 so as to rotate as the drive link 9 rotates. And a contact piece 11 for bringing a lower portion of the opening and closing body 7 into contact with the back surface of the opening and closing body 7 and separating the lower end of the opening and closing body 7 from the front panel 1a. The open / close body 7 is driven by a drive motor 8 and the drive link 9.
Is rotated to separate the upper portion of the opening / closing member 7 from the front panel 1a so that air can be sucked from the suction port 2 at the upper portion of the front surface. Further, the lower end of the opening / closing body 7 which rotates and abuts on the contacting piece 11 is separated from the front panel 1a. This makes it possible to solve the problem, and has a structure in which the opening and closing body 7 can open and close the suction port 2 at the upper part of the front surface according to the amount of suction air while improving the design.

An urging means for urging the lower end of the opening / closing member 7 toward the front panel 1a is attached to a connection portion between the drive link 9 and the opening / closing member 7. The torsion coil spring 10 is locked to the locking portion 10a of the opening / closing body 7, whereby the lower end of the opening / closing body 7 can be constantly biased toward the front panel 1a. Thus, the opening / closing body 7 has a structure in which the opening / closing body 7 does not rattle.

A first stopper 12 for positioning the drive link 9 on the front panel 1a or the drive motor 8 at a position where the opening 2 on the front surface is closed by the opening / closing member 7; The lower end of the front panel 1a
The second stopper 12 that is positioned at a predetermined position away from the
With this arrangement, the rotation angle of the drive link 9 driven by the drive motor 8 can be accurately regulated to a predetermined angle.

Further, a bush 13 abutting on the front panel 1a is additionally provided at the lower end of the opening / closing body 7, so that the lower end of the opening / closing body 7 urged by the torsion coil spring is connected to the bushing. The front panel 1a is brought into contact with the front panel 1a through the opening 13, so that the lower end of the opening / closing body 7 and the front panel 1a are not mutually damaged so that the design is not impaired.

Further, the bush 13 is provided along the longitudinal direction of the lower end of the opening / closing body 7 so that the lower end of the opening / closing body 7 can be accurately protected in the longitudinal direction.

The bush 13 is made of a synthetic resin having lubricity, so that the lower end of the opening / closing body 7 is connected to the front panel as shown in FIG.
When moving upward while maintaining contact with 1a, the structure is such that the movement can be performed more smoothly, and the lower end of the opening and closing body 7 and the front panel 1a are not damaged from each other.

The drive shaft 8a is formed to have a substantially elliptical cross section. As shown in FIG. 2, when the opening / closing body 7 is rotated to separate the upper part thereof from the front panel 1a, By making the suction air flow sucked from the suction port 2 at the upper part of the front face pass through both sides of the short diameter portion having the substantially elliptical cross section, the air resistance by the drive shaft 8a can be suppressed to be small. It has a configuration.

Further, the drive shaft 8a having a substantially elliptical cross section is formed in a cylindrical shape, so that the drive shaft 8a is reduced in weight without reducing its strength.

Further, by providing the opening 7a in the opening / closing member 7, air can be sucked from the opening 7a and the suction port 2 on the upper surface when the amount of intake air is small depending on the operating condition, for example. As a result, an appropriate intake air amount can be supplied. The vent 7a
Since the opening and closing body 7 may be formed in a size and a shape capable of forming a necessary minimum ventilation path, the opening / closing body 7 has a degree of freedom in design that can enhance a design and have a characteristic. In addition, the configuration has an advantage that it can be formed into a shape to which fine dust and the like are not easily attached.

Further, since the ventilation hole 7a is constituted by a plurality of horizontal rails and / or a vertical rail connecting these, the opening / closing body 7 has an improved design as described above. Thus, the structure has a degree of freedom in design that can be given a characteristic, and can have appropriate strength.

A display unit 14 is provided below the front panel 1a.
The opening and closing member 7 is rotated to separate the upper part from the front panel 1a, and at the same time, the lower part of the opening and closing member 7 covering the lower part of the front panel 1a moves upward and the display unit
14, the drive link 8 is rotated by the drive motor 8 when the intake air amount is large depending on the operation state, as shown in FIG. When the lower end of the opening / closing member 7 is moved upward, the amount of intake air and the amount of air blown out from the outlet 3 become large, for example, indicating that strong air conditioning is being performed. The structure is such that the effect that the part 14 can be seen dramatically can be achieved.

Further, the display unit 14 is constituted by a printed display on which driving information is printed and / or an LED, whereby, as described above, the display unit 14 can be changed more dramatically. In addition, the structure has an effect of producing an effect of being clearly visible.

Further, the drive motor 8 comprises a stepping motor, and the drive link 9 can be sequentially rotated from the position of the first stopper 12 to the position of the second stopper 12 by the stepping motor. ,
The rotation angle of the drive link 9 can be changed linearly between the first stopper 12 and the second stopper 12 so that the amount of suction air sucked from the suction port 2 can be more finely adjusted. The configuration is as follows.

Furthermore, the drive link 9 is sequentially rotated, and the display section 14 is sequentially visible in response to the lower portion of the opening / closing body 7 moving upward. For example, it is possible to impress a stepwise change in the amount of suction air sucked from the suction port 2 by, for example, a scale or color change designed in the vertical direction.

With the above construction, as shown in FIGS. 1 to 3, the suction port 2 at the upper part of the front face is opened and closed by an opening / closing body 7 made of a decorative plate, and a driving device for driving the opening / closing body 7 is driven. A motor 8, a drive shaft 8a of the drive motor 8 and a drive link 9 having both ends connected to the open / close body 7; and the screw for urging the lower end of the open / close body 7 toward the front panel 1a. A biasing means comprising a coil spring 10 and a lower end of the drive link 9, the tip end of which is brought into contact with the back surface of the opening and closing body 7 as the drive link 9 is rotated,
A contact piece 11 for separating the lower end of the opening / closing body 7 from the front panel 1a. When a large amount of air is sucked from the suction port 2, the opening / closing body 7 is moved by the driving motor 8 and the driving link 9. It turns to separate the upper part of the opening / closing body 7 from the front panel 1a so that air can be sucked from the suction port 2 in the upper part of the front face. When the filter 6 is inserted and removed, the drive link 9 is further moved. The lower end of the opening / closing body 7 that rotates and abuts on the contacting piece 11 is the front panel 1a.
So that the above-described problems in the prior art can be solved, and the opening / closing member 7 opens and closes the suction port 2 in the upper part of the front surface in accordance with the amount of suction air while improving the design. In addition, the air conditioner is configured such that the display section 14 for displaying the driving information can be sequentially and accurately viewed.
