Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention mainly relates to an improvement of an air conditioning outlet device that is attached to the ceiling of a large office or the like and is used in connection with a hot air or cold air duct.

[Problems to be solved by conventional technology and invention]

The wind blown out from the air outlet device attached to the ceiling of the office may disturb the hair of the person directly below, blow away pieces of paper on the desk, or hit only some people directly and strongly. I didn't like it because it made me feel tired.

The present invention was devised for the purpose of solving such undesirable problems.

In addition, although various devices have been conventionally known for the purpose of solving such problems, the current situation is that they have not always been fully achieved.

[Means for solving problems]

In the present invention, when hot air (cold air) weaker than the duct is supplied, the weak hot air (cold air) is directed directly below the weak air outlet, and when similarly strong hot air (cold air) is supplied, the strong The pressure of the hot air (cold air) opens the on-off valve according to the size of the air pressure, directing part of the hot air (cold air) to the direction of diffusion diagonally downward from the strong wind outlet, and distributing the rest. This is an attempt to avoid the above-mentioned undesirable problem by devising a way to discharge the air directly below the weak wind discharge holes.

〔Example〕

The embodiment shown in the figure has ducts (not shown) on the upper walls 4 and 5 of the inner box part 2 and the outer box part 3 in a box body 1 which has a single wall structure on the lower surface and a double wall structure on the other surface. The lower end of the tubular cap 6 for connection to the inner box portion 2
The inner box part 2 is fixed in a mutually intersecting state with its upper end opening to the outside of the outer box part 3.
A plurality of communication holes 8 are provided at a location between the top wall 4 and the top wall 5 of the outer box part 3, and a guide blade 10 is provided in the bottom wall 9 of the inner box part 2 in an obliquely downward direction of diffusion. A large number of strong wind discharge holes 11 are connected to the lower wall 1 of the outer box part 3.
2 are provided with ring-shaped weak wind discharge holes 14 each having a guide vane 13 directed directly downward, and a beam member 15 is provided across the base 6, and a female threaded rod 16 is vertically installed in the middle of the beam member 15. Fix the female threaded rod 1
A male threaded rod 18 with a brim-like head 17 is screwed into the male threaded rod 18 from below, and a conical opening/closing valve 20 whose entire peripheral edge 19 is in pressure contact with the lower edge of the base 6 and is in a fully closed state is vertically slid onto the male threaded rod 18. Freely supported and same male screw rod 18
In the place between the flanged head 17 and the on-off valve 20,
A coil spring 21 is wound around the opening/closing valve 20 and a baffle plate 22 is mounted on the top surface of the opening/closing valve 20. When the wind pressure is above a specified value, the degree of opening varies steplessly according to the magnitude, and when the wind pressure is below a specified value, the opening degree is varied steplessly and closes when the wind pressure is above a specified value. A noise-reducing sponge 2 is placed on the contact surface of the on-off valve 20 at the lower edge of the cap 6.
A slot 24 is provided at the lower end of the male screw rod 18 so that the male screw rod 18 can be turned with a screwdriver to adjust the strength of the coil spring 21.

In the present invention, the on-off valve 20 may be constructed from a perforated plate.

[Action and effect of the invention]

Since the present invention has the above-described configuration, when hot air (cold air) weaker than the duct is supplied, the weak hot air (cold air) is directed directly below the weak air outlet,
Similarly, when strong hot air (cold air) is being supplied, the strong hot air (cold air) uses the wind pressure to open the on-off valve in a width corresponding to the size of the wind pressure, and part of the hot air (cold air) is turned into a strong wind. In the direction of diffusion diagonally downward from the discharge hole,
In addition, the remaining parts are discharged directly downward from the weak wind discharge holes. So-called weak hot air (cold air) with short legs blows out directly below, and strong warm air (cold air) with long legs blows out diagonally, so the result is that the area affected by the wind current is almost the same whether it is weak or strong. To the same degree of height, that is, depending on the height of the influence range,
For example, it has the desirable effect of completely eliminating problems such as hair being disarrayed directly under a strong wind vent, small pieces of paper on a desk being blown away, and only people directly below being directly exposed to the strong wind. Furthermore, a beam member 15 is provided in the base 6, a female threaded rod 16 is vertically fixed in the middle of this beam member 15, and a male threaded rod 18 with a brim-shaped head 17 is screwed into the female threaded rod 16 from below. A conical opening/closing valve 20 whose entire circumferential edge 19 is in pressure contact with the lower end edge of the base 6 is supported on this male threaded rod 18 so as to be vertically slidable, and a flanged head 17 is supported on the male threaded rod 18 .
A coil spring 21 is wound between the on-off valve 20 and the on-off valve 20 to provide an elastic force to the on-off valve 20, which varies the degree of opening steplessly according to the wind pressure when it is above a specified value, and closes when it is below. Therefore, the structure is such that the strength of the on-off valve 20 is automatically adjusted without a special drive device (for example, an electric device, etc.), and the operation is reliable.
