[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower and a method for manufacturing the blower.

[0002]

2. Description of the Related Art Conventionally, there has been proposed an air blower (blower) which is installed in, for example, a dryer or a dust collector.

The same components as those of the embodiment are denoted by the same reference numerals.)

A blower 4 according to this blower has a structure in which vanes 3 are radially arranged side by side at predetermined intervals between left and right substrate bodies 1 and 2. The board body 1 is integrally formed with an appropriate metal member so that the blade plate 3 protrudes from its inner surface, and then the other metal board body 1 is attached to one of the board bodies 2 from which the blade plate 3 protrudes. Are welded.

When the blower 4 rotates in the case body, air is sucked into the blower 4 from an opening 1b provided at the center of one of the substrate bodies 1 and enters the blower 4. The air is exhausted from the space between the blades 3 to the outside of the blower 4 by centrifugal force. The air volume and pressure of the air generated from the blower 4 depend on the radiation angle R of the blades 3 (rotation of the blower 4 It can be changed by changing the angle with respect to the axis L and the thickness (the width of the substrate body in the interval direction).

However, the blower 4 proposed in the prior art has a structure (in which the substrate 1 provided with the blades 3 is provided by integrally molding a metal member). It is difficult to always keep the angle and size constant (the radiation angle R and size of the slat 3 cannot be adjusted after assembling), and if the result is incomplete, the design is changed ( Because of the necessity of balancing), its production requires extremely high-precision technology, and furthermore, it is necessary to produce each of the blowers 4 having conditions capable of generating the air volume and pressure required by the user. Since a dedicated mold is required, there are problems such as extremely low productivity and high cost.

[0007] In view of the above problems, the present invention has been subjected to various studies, and as a result, has invented a very practical and extremely innovative blower and a method of manufacturing the same.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention and will be described below.

The present embodiment is a blower 4 in which a blade 3 having a predetermined width is radially provided between the left and right substrates 1 and 2, and the blade 3 is formed by a rotation axis L of the blower 4. Is provided so that the radiation angle R with respect to the angle can be set arbitrarily.

Hereinafter, each component of the embodiment will be described in detail.

As shown in FIG. 1, each of the substrate bodies 1 and 2 is formed by forming an appropriate metal member into a disk shape, and one of the substrate bodies 1 has a circular opening 1b at the center thereof. Is formed.

The substrate bodies 1 and 2 have through holes 1a and 2a respectively formed at predetermined locations.

The through holes 1a and 2a are holes for inserting fixing bolts as screw members 7 when the blade plate 3 is fixed to the substrate bodies 1 and 2. By fixing the blade 3 at the position 2a, the blade plate 3 is attached to the inner surface of the substrate 1 at a predetermined radiation angle R with respect to the rotation axis L of the blower 4.

The blade 3 is constituted by a plurality of divided blades 5.

As shown in FIGS. 1 and 6, the divided blade plate 5 is formed by integrally molding a member made of a suitable synthetic resin. One slat 3 is formed by laminating five sheets in the direction of 2.

Each of the divided blades 5 has three holes 5a formed in three places. When the holes 5a are stacked between the substrates 1 and 2, the through holes 1a formed in the substrates 1 and 2 are formed. , 2a
In this state, the fixing bolt 7 is fitted and inserted, and is fixed to the substrate body 1 or 2.

Next, a method of assembling the blower 4 according to this embodiment will be described.

First, the blade 3 is formed by laminating the divided blades 5 on the inner surface of the one substrate 2 in the direction of the space between the left and right substrates 1 and 2. At this time, the blade 3 is
Are disposed at a predetermined radiation angle R with respect to the rotation axis L.

After arranging the respective blades 3 on the substrate 2 in this manner, the other substrate 1 is laminated on the end surface of the blade 3,
In this state, the blowers 4 are completed by integrating the substrates 1 and 2 and the blades 3 via the fastening bolts 7.

Further, when the blower 4 according to the present embodiment is rotated in the case body, air is sucked into the blower 4 from an opening 1b provided at the center of one of the substrate bodies 1, and this blower is blown. The air that has entered the body 4 is discharged out of the blower 4 from between the blades 3 by centrifugal force.

The air volume and pressure of the air generated from the blower 4 according to this embodiment are determined by the radiation angle R (the angle of the blower 4 with respect to the rotation axis L) and the thickness (the distance between the substrates). (Width in the direction) can be changed.

Since the present embodiment is constructed as described above, the mounting state of the blade plate 3 between the substrate bodies 1 and 2 can be freely set as shown in FIGS. Since the angle adjustment of the slats 3 can be easily performed when the slats 3 are mounted, there is no waste as in the above-described conventional example, and the conditions such as the air volume and the wind pressure required by the user can be easily obtained. It is very convenient,
In addition, it is excellent in cost and manufacturing.

That is, in the case of the conventional configuration, if the product is not as designed and the radiation angle R and the size are poor, the mold is wasted, and even if it is made as designed, there are various conditions. If it is found that there is an inconvenience after use depending on (use condition, material), the die is also wasted (in this case, it is difficult to balance separately in this case). In this regard, according to the present embodiment, since the blade plate 3 is provided separately from the substrate body 1,
Even if the mounting angle of the wing plate 3 to the wing is not good, only the substrate body 2 needs to be replaced, and the mounting of the wing plate 3 can be performed extremely easily, so that the angle adjustment can be performed very simply and at low cost.

In this embodiment, since the blade plate 3 is composed of a plurality of divided blade plates 5, the width of the blade plate 3 (the width in the direction of the space between the left and right substrates 1 and 2) is changed. Therefore, the conditions such as the air volume and the air pressure required by the user can be more easily obtained.

In this embodiment, the high quality blade plate 3 can be obtained very easily because it is made of a synthetic resin which is simple but can be molded with high precision. Thus, the entire blower 4 can be manufactured lightly and at low cost.
