Description

[Detailed description of the invention] Industrial application field The present invention relates to a blowing device for an air shower for a clean room, and eliminates the cause of dust generation from the blowing device, thereby making it possible to blow out air from an air shower with a high degree of cleanliness. This is what I am trying to do.

BACKGROUND TECHNOLOGY Conventionally, in the blowing device of an air shower for use in a clean room, a method has been adopted in which the blowing body of the air shower is rotatably installed in the intended installation area via a cushion material made of elastic fibers such as felt. Ta. Although this method has the advantage of a simple structure and the ability to move the air shower outlet of the blower to any angle, the cushion material becomes a source of dust, and the supplied clean air is It had the disadvantage of causing contamination.

Problems to be Solved by the Invention The present invention attempts to solve the above-mentioned problems, and is capable of directing the supplied clean air from the outlet of the blowing body while keeping it clean, and also by using the air shower of the blowing body. The aim is to make it possible to move the outlet port to any angle.

Means for solving the problems In order to solve the problems mentioned above, the present invention
A spherical blowing body is formed by providing an inlet and an outlet for clean air, and a support body is rotatably fixed to two points on the peripheral wall of the blowing body through the axis of the blowing body, and this support The body is rotatably fixed to a fixed frame fixed to the intended installation part of the blow-off body with two fixed shafts located on a straight line through the axis of the blow-off body, and these two fixed shafts are rotated. The shafts are formed at 90 degrees from each other, and the outlet of the blower body is protruded from the protruding opening in the intended installation part, and the outer circumferential surface of the blower body and the protruding opening are opposed to each other without any intervening material. It is something.

Function Since the present invention is constructed as described above, there is no need to install the blowing body of the air shower in a rotatable manner at the intended installation site via a cushion material made of elastic fibers such as felt, and the generation of dust is eliminated. The blower body can be installed at a target position without using an inclusion that becomes a source, and the blowing direction of the air shower of the blower body can be set in exactly the same manner as before. That is, if the blower body is rotated according to the rotating axis of the support body, the blower body is fixed to two points on the outer circumferential wall via the axis, and the support body is rotatably fixed around the rotation axis. , following the rotation axis.
Allows for 180 degree rotation. Also, this support
If the support body rotates according to the fixed axis of the fixed frame,
It is rotatably fixed to the fixed frame with two fixed axes located on a straight line, and these two fixed axes are referred to as the rotating axes.
Since they are formed at 90 degree positions, it is possible to rotate in a direction that is 90 degrees different from rotation along the fixed axis. Therefore, the blower body can be rotated in 360 degrees, and the outer peripheral surface of the blower body can be placed opposite the intended installation area without intervening objects, making it possible to blow out a clean air shower. It is something.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a blowing body, and a part of a spherical outer circumferential wall 2 is cut out to form an inlet 3 for clean air. A clean air outlet 4 is provided on the opposite side of the air outlet 3. A support 5, which is annularly located around the outer periphery of the spherical blow-off body 1, is rotatably fixed to two points on the outer surface of the outer circumferential wall 2 via the axis of the spherical blow-off body 1. There is. Then, this support body 5 is attached to the blowing body 1
It is rotatably fixed to a fixed frame 10 fixed to the installation target part 8 with two fixed shafts 11 and 12 located on a straight line through the axis of the blowing body 1, and these two fixed shafts 11, 12 are formed at positions of 90 degrees from the rotation axes 6 and 7, respectively. The installation purpose part 8 may have any shape depending on the purpose of installation as long as it has a protruding opening 14 through which the outlet 4 of the blowing body 1 can protrude. like,
It may be fixed to the bottom wall 17 of a conical recess 16 provided with a connecting flange 15 on the outer periphery. In addition, the outlet 4 of the blower body 1 is projected from the protruding opening 14 of the installation target portion 8 without using an intervening material such as felt, and the installation target portion 8 and the outer peripheral wall 2 of the blower body 1 are connected to each other through an intervening material such as felt. The protruding opening 14 can be opened without intervening objects.
is facing.

In the configuration as described above, the blowing body 1
If rotated according to the rotation axes 6 and 7 of the support 5,
Since the blowing body 1 has a support 5 rotatably fixed to two points on the outer circumferential wall 2 via the axis center with rotation axes 6 and 7, the blower body 1 has a support body 5 rotatably fixed at two points on the outer circumferential wall 2 through the axis. allows for rotation. Further, this support body 5 is attached to a fixed frame 10.
If the supporting body 5 is rotated according to the fixed shafts 11 and 12 of fixed, and these two fixed shafts 11 and 12,
Since the rotation axes 6 and 7 are formed at 90 degrees, rotation according to the rotation axes 6 and 7 means 90 degrees.
It is possible to rotate 180 degrees in different directions. Therefore, the blower body 1 can be rotated in 360 degrees, and the outer peripheral surface of the blower body can be installed facing the installation target part 8 without intervening objects, making it possible to blow out a clean air shower. That is.

Further, in the above embodiment, the support body 5 was formed in an annular shape around the outer periphery of the blowing body 1, but in other different embodiments, the support body 5 was formed in a linear shape as shown in FIG. and its both ends are connected by rotating shafts 6 and 7.
A supporting member 18 fixed to the inner surface of the blowing body 1, and a rising portion 1 projecting outward from the center of the supporting member 18.
A fixed frame 10 is fixed to the U-shaped member 20 of the support body 5 with a fixed shaft 11. Also in this example,
The blowing body 1 operates in exactly the same manner as in the previous embodiment.
Enables clean air shower to be emitted in 360 degrees.

Effects of the invention Since the present invention is constructed as described above, there is no need to install the blowing body of the air shower in the intended installation part via a cushion material such as felt when blowing out the air shower for a clean room. Eliminates the drawback that the cushion material is a source of dust, allows the supplied clean air to be directed out of the outlet of the blower while remaining clean, and allows the outlet of the air shower of the blower to be set at any angle. It is.
