Description

[Detailed description of the invention] [Field of industrial application] This invention is a method for blowing out air-conditioned air from the ceiling etc. into rooms to be air-conditioned such as clean rooms, bio-clean rooms, clean rooms for manufacturing precision machinery, and various animal rooms. More specifically, the present invention relates to an air blower for air conditioning equipped with a face for forming a blower outlet in which a plurality of blowholes are dispersedly formed.

[Conventional technology]

As shown in FIG. 7, this type of air-conditioning air blower has a plurality of blades 3 arranged in parallel at intervals.
There are those equipped with a face 3 that changes the blowing direction by swinging a, and as shown in Fig. 8,
An anemo-shaped face 3 that changes the blowing direction by changing its position in the blowing direction of the cone 3c, or a face 3 that changes the blowing direction by swinging the tube 3d as shown in FIG. There have been conventionally known devices equipped with the following.

[Problems to be solved by the invention] However, the conventional blower for air conditioning has the following disadvantages.

In other words, in the first type, the position of the blow-off holes formed between adjacent blades in the blow-out direction is constant, so the degree of freedom in changing the blow-out direction is small. Since the size of the blowout hole also changes, it is possible to optimize both the blowout direction and the blowout amount in each blowout direction, for example, if emphasis is placed on directionality, the blowout amount in that blowout direction will not be optimal. It's difficult.

In the second type, the shape of the cone is constant and the blowing direction is changed only by changing the position of the cone in the blowing direction, so the degree of freedom in changing the blowing direction is small. Since the amount of blowing in each direction also changes, it is difficult to optimize both the blowing direction and the blowing amount in each blowing direction, as in the first case.

In the third type, only the air blown out from the blow-off hole formed by the cylinder is subject to change in blow-off direction, so the degree of freedom in changing the blow-off direction is small.

In short, with conventional air-conditioning air blowers, although the blowing direction can be changed to some extent, the range of change in the blowing direction is small and the blowing form cannot be changed significantly, and as a result, the blowing can be performed in a way that meets the conditions. To do this, you have to prepare multiple types of cones with different numbers and shapes of blades, different sizes and shapes of cones, and different sizes and shapes of tubes, and select the one that meets your conditions from among them. Not necessarily,
As a result, the workability is poor and the cost is high.

An object of the present invention is to provide an air blower for air conditioning that can produce a variety of blowing forms. [Means for solving the problems] The characteristic configuration of the air blower for air conditioning according to the present invention is as follows:
The face is formed into a container shape from a material that is flexible and has self-retaining properties, and the face is provided with a support that supports an intermediate portion of the face, and a position of the intermediate portion of the face that is supported by the support. The point is that a face shape adjusting means for changing the face shape is provided. The effects and effects thereof are as follows.

[Effect]

The face is flexible and self-retaining, and can be changed into various shapes as shown in Figure 3 A, B, C, and D by means of a face shape adjustment means, and can be changed to various shapes by means of a face shape adjustment means, and can be changed to various shapes as shown in FIG. The support and its self-retention properties allow it to maintain its shape against the blowing air pressure. By changing the shape as described above, the direction and position of the blow-off hole can be adjusted. In this way, the blowing direction can be changed by adjusting the direction and position of the blowing hole, so that a variety of blowing forms can be created.

[Effect of idea]

As a result, the present invention is able to create a blowout form that is suitable for the conditions, only requires one type, reduces costs through mass production, is superior in workability, and is suitable for use in clean rooms where delicate air blowing is required. It has now become possible to provide an air blower for air conditioning that is extremely useful as a product.

〔Example〕

Next, an example of the present invention will be shown.

As shown in Figures 1 and 2, this is a blower for blowing out air conditioning air from the ceiling. It consists of a face 3 for forming an air outlet attached to a frame 2.

The face 3 is attached to a mounting frame 3A to the frame 2.
And the face main body 3B attached to this mounting frame 3A
The mounting frame 3A includes the blowout opening 1.
Face main body 3B in the covering position and opening position.
It is attached to one side of the shaft via a hinge 4 so as to be able to swing vertically.

The face main body 3B is formed into a truncated conical container shape from a flexible and self-retaining material (synthetic resin, etc.), excluding the bottom part and the peripheral part attached to the mounting frame 3A. A plurality of blow-off holes 3b are formed in a distributed manner in the portion. A handle 3c is integrally formed on the outer surface (lower surface) of the bottom.
The face main body 3B is a colorless or colored transparent body, and the bottom portion is constructed separately.

The blower also includes a chain 6 as a support for suspending and supporting the bottom part (an example of the middle part) of the face main body 3B from a bar 5 connected to the mounting frame 3A, and a chain 6 as a support for suspending and supporting the bottom part (an example of the middle part) of the face main body 3B; and face shape adjusting means for changing the position relative to the bar.

The face shape adjusting means includes the chain 6
This is a means for changing the effective length of the chain 6 by changing the link 6a to be locked to the bar 5.

In the above configuration, by changing the effective length of the chain 6 and deforming the face main body 3B, the face main body 3B can be changed as shown in FIG.
It can be made into various shapes as shown in C and D. Note that the work of changing the effective length of the chain 6 and the work of deforming the face main body 3B are
This is done with the face 3 in the open position.

Incidentally, in the face 3 shown in FIG. 3A, the face main body 3B is formed into a conical shape with the bottom part farthest from the bar 5. In this case, all of the blow-off holes 3b face diagonally downward, and the face body 3B is shaped conically. As a result, all of the supplied air is blown out obliquely downward and in the radial direction away from the center of the blower.

The face 3 shown in FIG.
Among them, the face main body 3B is deformed so that the inner circumferential part connected to the bottom is located horizontally at the same level as the bottom, and in this case, the air is formed in the conical outer circumferential part. Blowout hole 3b

The face 3 shown in FIG. 3C has its bottom closest to the bar 5, and the face body 3B is deformed so that the inner circumference around the bottom has a conical shape with the bottom at the top. In this case, the air flows obliquely downward from the blow-off hole 3b formed in the outer circumferential portion of the conical shape, and
The air is blown out in the radial direction away from the center of the blower, and is blown out diagonally downward from the blow-off hole 3b formed in the inner circumferential portion and toward the center of the blower, and the outer circumferential portion and the inner circumferential portion are The air is blown downward from the blow-off hole 3b formed at the connecting part.

The face 3 shown in FIG. 3D has the bottom portion moved closer to the bar 5 to some extent, and the face main body 3B is deformed so that the outer peripheral part of the face main body 3B is cylindrical and the inner peripheral part is positioned horizontally. In this case, air is blown out horizontally and in a radial direction away from the center of the blower from the outlet 3b formed on the outer circumference, and air is blown out from the outlet 3b formed on the inner periphery. It is blown out downward from the top.

In addition, in the face 3 shown in FIG. It is maintained through the cooperation of
