DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower for blowing air to workers in a house where plants grow.

[0002]

2. Description of the Related Art In a house where plants such as flowers and vegetables are grown, the temperature is high and humid particularly in the summer, and an extremely severe environment is required for workers working in the house. For this reason, a blower that blows air toward the worker and improves the environment of high temperature and humidity to improve the work efficiency of the worker is used. The above-mentioned conventional blower generally uses a stand-type fan in which a fan is attached to an upper end of a stand.

[0003]

The stand-type fan used as the above-mentioned conventional blower has a stand having a relatively heavy fan mounted on an upper end thereof, and ensures stability when the stand is placed on the ground. The stand is made sturdy and heavy to prevent falls. For this reason, the conventional stand-type fan is extremely heavy for an operator to carry, and it is not easy to move the installation location together with the work location. In addition, the installation place is limited to a passage in the house or the like, which hinders the work. Therefore, stand-type fans are arranged one by one in a place in the house that does not interfere with the work. As a result, when the area of the house becomes large, the number of necessary stand-type fans increases, and there is a problem that the cost of the business increases.

Accordingly, an object of the present invention is to provide a blower that is easy to carry and can be used by hanging it on a horizontal breath of a house.

[0005]

The above object can be attained by a blower according to the present invention. According to the blower according to the first aspect, when the brace engaging member to which the hanger member is attached in a suspended manner is hung by the horizontal brace extended in the house vertically and horizontally, it is attached to the lower portion of the hanger member. When the blower is suspended and power is supplied to the blower, the blower starts. The blower needs only to have a strength capable of suspending the blower, and does not need to be made strong and heavy in order to prevent it from falling down unlike the stand of the conventional stand type fan. Therefore, the total weight including the hanger member, the breath hooking member and the blower is lighter than that of a conventional stand-type fan, and the portable device is easy to carry. Further, since the air is blown while being hung by the horizontal breath, it does not hinder the work. As a result, even if the area of the house is large, the number of required blowers is extremely reduced as compared with the conventional case.

According to the blower according to the second aspect, the breath catching member can catch either a round bar-shaped horizontal breath or a rectangular horizontal breath, and can be used in most houses.

According to the third aspect of the present invention, the hanger member is provided with the position adjusting means for adjusting the position of the hanger member with respect to the breath retaining member, so that the height of the blower can be appropriately adjusted. .

According to the blower of the fourth aspect, since the hanger member is rotatable with respect to the breath catching member hooked on the horizontal breath, the direction of the blower can be arbitrarily changed. Thereby, the blowable range can be widened.

According to the blower device of the fifth aspect, the hanger member is positioned on the vertical center axis of the hanger member in a state where the hanger member is suspended and attached to the breath retaining member. In addition, the inclination of the blower is suppressed, and the suspended state is stabilized.

[0010] According to the blower mounting device of claim 6,
It is only necessary to have a strength capable of suspending the blower, and it is not necessary to make it strong and heavy to prevent it from falling down like the stand of the conventional stand type fan. Therefore, the total weight including the hanger member, the breath hooking member and the blower is lighter than that of a conventional stand-type fan, and the portable device is easy to carry.

[0011]

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing a state in which a blower 1 is suspended from a horizontal breath 3 in a house 2. Generally, the inside of the house 2 is hot and humid especially in summer,
The environment becomes severe for the worker 4. In order to improve such an environment, the blower 1 is suspended from a horizontal breath 3 in the house 2, and air is blown from the fan 5 of the blower 1 to the worker 4. FIG. 2 is a side view of the blower 1. As shown in FIG. 2, the blower 1
The breathing member 6 is hooked to the horizontal breath 3 inside, and the breathing member 6 is integrated with the hooking piece 7 that hooks on the horizontal breath 3 from above and the hooking piece 7. And a cylindrical collar 8.

Generally, since the horizontal breath 3 in the house 2 is a round bar or a square bar, the hooking piece 7 is made of a first hooking piece 7a hooked on the round bar-shaped horizontal breath 3a. , And a second latching piece 7b latched to the rectangular horizontal breath 3b is formed integrally.

The upper portion of a hanger member 9 made of a lightweight round pipe is inserted through the collar 8. The hanger member 9 has an upper part 9a and an intermediate part 9b formed vertically, an inclined part 9c between the upper part 9a and the intermediate part 9b, and a lower part 9d formed horizontally. A fan mounting plate 10 for fixing the fan 5 with bolts or the like is attached to a lower portion 9d of the hanger member 9. The fan mounting plate 10 is mounted such that when the fan 5 is fixed to the fan mounting plate 10, the center of gravity of the fan 5 is located on the extension of the hanging center axis of the hanger member 9.

The hanger member 9 inserted through the collar 8
A hanger ring 11 is fixed to the upper part 9a of the base member so as to be adjustable in position coaxially with the collar 8. The hanger ring 11 has a plurality of holes 9 previously formed in the hanger member 9.
f (see FIG. 4), a tap hole (not shown) into which the wing bolt 12 to be inserted is screwed is formed. When the fixing position of the hanger ring 11 is determined, the wing bolt 12 is screwed into the tap hole, screwed, and inserted into any one of the holes 9f. When the hanger ring 11 is fixed to the uppermost part of the position adjustable range of the hanger member 9, that is, the hanger ring 11 is fixed to a position where the hanger ring 11 contacts the upper limit pin 9e attached to the uppermost part of the hanger member 9. In this case, the hanger member 9 is positioned at the lowest position, and the position of the electric fan 5 is lowest. Conversely, when the hanger ring 11 is fixed at the lowermost position in the position adjustable range, the hanger member 9 is positioned at the highest position, and the position of the electric fan 5 is highest.

When four tap holes 13a (refer to FIG. 4) are formed in the hook 7 and the first hook 7a is hooked on the horizontal bar-shaped breath 3a, the upper When the two wing bolts 13 are screwed into the two tap holes 13a and screwed forward, the tips are pressed against the horizontal breath 3a.
This locked state is stabilized. Similarly, when the second hook piece 7b is hooked on the rectangular horizontal breath 3b, two wing bolts 13 are screwed into the lower two tap holes 13a, and the screw is advanced. Because the tip is pressed,
This locked state is stabilized. The nuts 13b screwed to the respective wing bolts 13 prevent the respective wing bolts 13 from being loosened.

The wing bolt 14 screwed to the collar 8
When the screw is advanced, the tip portion abuts on the peripheral surface of the hanger member 9 to prevent the hanger member 9 from rotating. The nut 14a prevents the wing bolt 14 from loosening. When the tip of the wing bolt 14 is not in contact with the peripheral surface of the hanger member 9, the hanger member 9 can rotate 360 degrees with respect to the collar 8.

A leg 15 is attached to the lower side of the fan mounting plate 10 so that the blower 1 can be used by placing it on the ground.

FIG. 3 is a side view of the blower 1 without the fan 5, FIG. 4 is a rear view of FIG. 3, and FIG. 5 is a plan view of the fan mounting plate 10.

As described above, the blower 1 is composed of lightweight members such as the breath retaining member 6, the hanger member 9, the fan mounting plate 10, and the like, and the fan 5 is attached thereto. Extremely lightweight compared to a stand-type fan, and easy to carry.

Next, the operation of the blower 1 will be described. In a state where the blower 1 is assembled as shown in FIG.
As shown in FIG. 1, when the retaining piece 7 of the breath retaining member 6 is suspended on the horizontal breath 3 in the house 2, the electric fan 5 is suspended from the horizontal breath 3. In this state, an appropriate height and direction of the fan 5 for blowing air from the fan 5 to the worker 4 are determined. First, the height of the electric fan 5 is determined. When the height of the electric fan 5 is determined, the fixing position of the hanger ring 11 at which the electric fan 5 has an appropriate height is determined as described above. When fixing the hanger ring 11 at that position, a wing bolt 12 is screwed into a tap hole formed in the hanger ring 11, screwed, and inserted into one of the holes 9 f formed in the hanger member 9. .

Next, an appropriate direction of the electric fan 5 is determined. When determining the direction of the electric fan 5, the wing bolt 14 is loosened so that the hanger member 9 can freely rotate. When the fan 5 is tightened at a position where the fan 5 faces the operator 4, the tip of the wing bolt 14 contacts the peripheral surface of the hanger member 9 and locks the rotation of the hanger member 9. Then, the nut 14a is tightened to prevent the wing bolt 14 from loosening.

As described above, when the power supply voltage of 100 volts is supplied to the electric fan 5 in a state where the height and the direction of the electric fan 5 are determined, the electric fan 5 is driven and blown to the worker 4. Electric fan 5 when multiple workers are working nearby
When the so-called swing operation is performed, air is sequentially blown to a plurality of workers. Further, even if the worker 4 moves the work position as the work progresses, the fan 5 is rotated by 360 degrees by the rotation of the hanger member 9 as described above. In the range obtained, the position of the blower 1 does not need to be changed.

As described above, since the fan 5 is fixed to the fan mounting plate 10 and the center of gravity of the fan 5 is located on the extension of the hanging center axis of the hanger member 9,
In a state where the blower 1 is suspended from the horizontal breath 3, the fan 5 has a very small inclination and is stable. Further, as described above, since the leg pieces 15 are attached to the lower side of the fan attachment plate 10, the blower 1 can be placed on the ground and used. Moreover, although the electric fan 5 was used as a fan, it is not limited to an electric fan.
