Ribs are so formed inside a bent part 22 of the member 16 as to reduce a longitudinal direction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a blowing device, for example,
The present invention relates to a blowing device suitable for blowing cold air at a low speed in a food factory or the like so as not to lower the sensible temperature of an operator.

[0002]

2. Description of the Related Art As a device of this type, a duct which is arranged on or near a floor and has an upward air outlet on its peripheral wall and a downward pipe which is bent in an inverted L shape and is connected to the air outlet. It is known to have a cloth other end opening closing blowout member having one end opening.

[0003]

In the above-mentioned conventional apparatus, the inner portion of the bent portion of the outlet member is crushed irregularly. Therefore, the crushed portion not only has an unsightly appearance, but also has a large air resistance.

Further, it is conceivable that the bent portion is three-dimensionally cut and sewn so that the bent portion is not crushed, but this is time-consuming and causes a high cost.

An object of the present invention is to provide an conditioned air blowing device that solves the above problems.

[0006]

SUMMARY OF THE INVENTION An air-conditioned air blower according to the present invention includes a duct which is arranged on or near a floor and has a peripheral wall provided with an upward blowout port, and a duct which is bent in an inverted L-shape and blows out. And a cloth other end opening closing outlet member having a downward one end opening connected to a blower, and the inside of the bent portion of the outlet member is crimped so as to shrink it in the lengthwise direction. It is characterized by that.

[0007]

In the conditioned air blowing device according to the present invention, the inside of the bent portion of the air outlet member is crimped so as to shrink it in the lengthwise direction. Since it is kept in the shape of, the same part is prevented from being crushed irregularly.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, a steel duct 14 extends in the left-right direction along a rear wall surface 13 near a floor 12 of a room 11. On the peripheral wall of the duct 14, a plurality of upward air outlets 15 are provided at intervals in the duct length direction. A lower end opening of an inverted L-shaped outlet member 16 is connected to each outlet 15.
The outlet member 16 is formed of a breathable cloth in the shape of an elongated bag, extends upward from the duct 14, and has an upper end ceiling.
It is composed of a vertical portion 21 reaching near 17 and a bent portion 22 connected to the upper end of the vertical portion 21 and a horizontal portion 23 extending forward from the bent portion 22 and the front end reaching near the front wall surface 18. . The front end opening of the horizontal portion 23 is closed.

In a natural state in which air is not supplied to the air outlet member 16, the air outlet member 16 is crushed and becomes open, but when air is supplied to the air outlet member 16, the air outlet member 16 is opened.
Bulges into a cylindrical shape.

A drive pulley 32 with a motor 31 is provided behind the lower end of the vertical portion 21 of the duct 14, and a driven pulley 32 is provided above the front end of the horizontal portion 22 thereof.
33 has a pair of guide pulleys 34,
35 are arranged, and an endless rope 36 is wound around these pulleys 32 to 35.

A plurality of suspension rings 37 are attached to the outlet member 16 at intervals in the length direction of the outlet member. On the other hand, the rope 36 is provided with a suspender 38 to which a suspension ring 37 is detachably attached so as to correspond to the suspension ring 37.

Referring to FIG. 2, inside the bent portion 22, a plurality of pleats 41 arranged in the lengthwise direction thereof are attached,
As a result, the inner portion is contracted.

FIG. 3 shows how the pleats 41 are attached. In the portion that should be the bent portion 22 of the blowout member 16 in a natural state, a plurality of strings 42 arranged in the width direction of the blowout member 16 are arranged so that the front and back surfaces of the cord 42 alternate at regular intervals. The string 42 is sewn to the same portion in a state where the string 42 is pierced and pulled so that a wavy wrinkle is formed on the same portion.

When air is supplied to the sewn-out outlet member 16 of the cord 42, the outlet member 16 swells and the creases are overlapped at the bent portion 22, as shown in FIG.
A beautiful fold 41 can be attached.

As shown in FIG. 4, when the suspension wheel 37 is hooked on the suspending tool 38 on the floor 12 in sequence and the drive sprocket 32 is driven in the counterclockwise direction in FIG.
36, and finally, as shown in Fig. 1,
The outlet member 16 is in a state in which the set is stretched in an inverted L shape, and the air is supplied in this state.

[0017]

According to the present invention, since the inner portion of the bent portion is kept in a constant shape by the pleats, the irregular portion is prevented from being crushed irregularly, so that the appearance of the bent portion is improved. It will not be damaged and the air resistance of the bent part will be reduced.
