Abstract

PURPOSE:To prevent an outlet device from producing a sliding sound so as to make it advantageous by fixing a sealing material consisting of a silicone plate with a fabriclike flexible texture to a circular periphery of a damper fixed to a damper shaft. CONSTITUTION:When a damper motor is actuated to blow air into a room through a grille 3, a damper 7 provided inside a cylindrical part 5 encased in a main body 2 is made to turn by 90 deg. from a horizontal position to a vertical position. Contrarily, when the supply of air to the room is stopped, the damper is made to turn by 90 deg. to assume the horizontal position. To the damper 7 all along its circular periphery is fixed a plate 8 of silicone resin with a fabriclike texture. Respecting the material applicable to this silicone plate 8, at least it is required that the friction coefficient of the material is not large and that the material is not smooth. The sealing material 8 is designed to press against the inner surface of the cylindrical part 5 so hard that, when the damper is turned, frictional resistance is produced therebetween as the damper turns, that is, with an effect to shut off heat to the surfaces of contact and with no involvement of a sliding sound.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air outlet device for a ceiling-embedded air conditioner.

BACKGROUND OF THE INVENTION Conventional buildings are equipped with ventilation and air conditioning units in the attic for air conditioning and ventilation. This ventilation air conditioning unit has a configuration in which air is emitted from an air outlet on the ceiling surface through a duct. This outlet has a configuration as shown in FIG. That is, a main body 2 having an adapter 1 serving as a duct connection port
and a grill lv3 joined to this main body 2.

This grid/l/3 is provided with a control plate 4 for adjusting the wind direction. A cylindrical portion 5 is provided inside the main body 2, and this cylindrical portion 5
A disc-shaped damper 7 fixed to a damper shaft 6 connected to a damper motor (not shown) is provided inside the damper 7, and the damper 7 is in contact with the inner periphery of the cylindrical portion 6 over the entire outer periphery of the damper 7, and is flexible. A sealing material 8 made of a resin material and having a smooth surface is fixed thereto. The tip of the sealing material 8 is strongly pressed against the inner circumference of the cylindrical portion 5 and is curved. In this way, when the cooled air and heated air are to be ventilated into the window, the damper 7 is rotated 90 degrees and oriented vertically to ventilate the air to the grille 3 side. To stop the air blowing, the damper 7 was further rotated 90° horizontally as shown in FIG. 2 to stop the ventilation into the window.

Problems to be Solved by the Invention In such a conventional configuration, the damper 7 is opened and closed by rotating 90' each time the air conditioning is started or stopped. Since the flexible sealing material 8 that slides between the inner surface and the inner surface of the cylindrical portion 6 has a smooth surface, sliding noise is generated when the flexible sealing material 8 rotates while being in contact with the inner surface of the cylindrical portion 6. Since this sliding noise is directly transmitted to the occupants through the grille 3, there is a problem in that it gives discomfort to the occupants.

The present invention solves the above-mentioned conventional problems, and aims to provide a good air outlet device that prevents the generation of sliding noise.

Means for Solving the Problem In order to solve this problem, the present invention includes a cylindrical part formed in the main body of the outlet device, and a circular damper fixed to the damper shaft inside the cylindrical part. The damper has a structure in which a sealing material of a flexible textured silicon plate is fixed to the outer periphery of the damper.

Effect: With this configuration, when the damper starts rotating from a horizontal position to an open vertical direction, the sealing material moves in a curved manner while coming into contact with the inner periphery of the cylindrical portion, and the surface of the sealing material is caused by friction. Since the coefficient is small, the generation of sliding noise is prevented.

EXAMPLE An example of the present invention will be described below with reference to FIG. Note that the same reference numerals as in the prior art indicate the same thing, and the explanation will be omitted. A cylindrical portion 6 is provided inside the main body 2, and a damper motor (not shown) causes the go! When blowing into the room from J/I/3, from the horizontal position of damper 7,
°Rotate to make it vertical. Furthermore, when stopping the air blowing into the room, the damper 7 is rotated 90 degrees to make it horizontal. The entire outer peripheral end of the damper 7 is made of resin and has a textured silicone plate 8 fixed to the damper 7, and the textured silicone plate 8 has at least a small coefficient of friction.
Moreover, it is not smooth, for example, the height of the peak is Rmax of about 25 μm in 100 meshes.

In the above configuration, as described above, the damper 7 rotates when blowing into the room or when stopping, but when rotating, it strongly contacts the inner circumference of the cylindrical portion 6. The sealing material 8 rotates while creating frictional resistance, that is, rotates while making intermittent contact with the contact surfaces, and no sliding noise is generated. In this embodiment, the material has a frictional resistance comparable to that of cloth, but it is also possible to eliminate the sound during rotation even if the material is uneven or wavy to the extent that there is no air leakage.

Effects of the Invention As is clear from the description of the above embodiments, the present invention has the effect of using a textured silicon plate fixed to a damper with a sealing material that has a low coefficient of friction and is not smooth.
It has all the effects of being able to prevent sliding noise when the damper is opened and closed, making it quieter, and eliminating discomfort for residents near the air outlet device.
