Description

[Detailed Description of the Invention] The present invention relates to a small air blowing device such as a hair dryer.

The purpose of the present invention is to provide a small-sized blower device that prevents air leakage and exhibits the desired high blowing efficiency, and at the same time suppresses the looseness of the lead wires and reliably prevents them from coming into contact with the fan.

In order to achieve the above object, the present invention forms a ventilation chamber that accommodates a fan and a motor, and an electrical equipment room that is separated from the ventilation chamber by a ventilation path and a partition wall that connects to the ventilation chamber and that houses control components inside the equipment case. At the same time, a notch is formed in the partition wall for passing the lead wire between the motor and the parts on the electrical equipment room side, and the notch is closed with a mounting member used for attaching the motor to the equipment case to reduce the size. This is a configuration of air blowing equipment.

Below, a hair dryer is listed as an example of this proposal, and the first
This will be explained in detail with reference to FIGS. 3 to 3.

1 is an equipment case for a small blower device, that is, an outer case for a band-type hair dryer, and a pair of left and right divided cases la and lb
It is constructed by joining two parts, and has a structure that can be divided into left and right parts.

Inside the outer case 1, there is a ventilation chamber 2, a ventilation path 3 connecting the ventilation chamber 2 and an air outlet (not shown), and an electrical equipment compartment 4.
The electrical equipment chamber 4 is located inside the handle portion of the outer case 1 and is separated from the ventilation chamber 2 by partition walls 5, 5.

The partition walls 5, 5 are integrally projected from the inner surfaces of the divided cases 1a, lb, respectively, and abut against each other when the divided cases 1a, lb are joined to partition the ventilation chamber 2 and the electrical equipment room 4.

Note that suction ports (not shown) are provided on both side walls of the ventilation chamber 2, that is, on both side walls of the divided cases la and lb.

Reference numeral 6 denotes an air blower consisting of a motor 7 and a centrifugal cuff 8 rotated by the motor 7, and is housed in the air blowing chamber 2 of the outer case 1.

The motor 7 is attached to a mounting angle 10 by screws 9, 9, and fixed within the outer case 1 using the mounting angle 10.

As shown in FIG. 3, this mounting angle 10 has both ends bent in the same direction so as to face each other, and an engaging piece 11 is formed at one end by folding back.

As shown in FIG. 2, this mounting angle 10 abuts on protrusions 12, 12 protruding from one of the divided cases 1a, and its one end abuts against the inner surface of the outer peripheral wall of the divided case 1a. The other end is in contact with the partition wall 5, and the engagement piece 1 is attached to the upper edge of the partition wall 5.
1.

In addition, a mounting angle 10 is provided on the inner surface of the outer wall of the divided case 1a.
Ribs 13, 13 are formed on both sides of the end of the partition wall 5, and ribs 14, 14 are formed on both sides of the anchor piece 11, respectively. Do the following.

Therefore, this mounting angle 10 is fixed using the split case la.
, lb.

That is, the mounting angle 10 is secured by clamping the end of the mounting angle 10 on the side of the engagement piece 11 between the partition walls 5, 5 of the split cases la and lb, and pressing the other end with the rib 15 of the split case 1b. Fix it.

It is of course necessary to form a notch in at least one of the partition walls 5, 5 in which the mounting angle 10 fits so that when the mounting angle 10 is clamped between the partition walls 5, 5, there will be no gap between them. It is.

Reference numeral 16 indicates a notch formed in the partition wall 5 of the divided case 1a, and is used to lead the lead wire 17 of the motor 7 to the electrical equipment room 4 side.

This notch 16 is formed at a position where the end of the mounting angle 10 abuts, and is narrower than the mounting angle 10.

Therefore, the mounting angle 10 closes the notch 16 while being fixed at a predetermined position.

Reference numeral 18 denotes a heat generating component assembly disposed in the air passage 3, whose lead wire 19 is led to the electrical equipment room 4 through between the outer peripheral wall of the divided case 1a and the partition wall 5, and is provided in the electrical equipment room 4 together with the lead wire 17. connected to control parts such as switches.

The present invention has the above-mentioned configuration, and the lead wire 1 of the motor 7
7 is located within the notch 16 of the partition wall 5, and the mounting angle 10 that closes this part 16 suppresses floating movements such as floating, so that the floating movement may come into contact with the fan 8 and cause the insulation coating to peel off. This eliminates inconveniences such as interference with the rotation of the fan 8.

In addition, the blower 6 can be assembled by joining the split cases la and lb and clamping the mounting angle 10, and by effectively utilizing the configuration in which the outer case 1 is assembled with the pair of left and right split cases la and lb, screws It can be easily installed without requiring any tightening or the like.

Furthermore, by closing the notch 16 on the peripheral wall of the ventilation chamber 2 with the mounting angle 1o as described above, air will not leak from the notch 16 into the electrical equipment room 4 when the fan 8 is rotating. Therefore, air can be blown to the air passage 3 side with high air blowing efficiency.

The mounting angle 10 may be configured to close at least the portion of the notch 16 corresponding to the fan 8, and the entire notch 16 (excluding the portion through which the lead wire 17 is inserted) is sufficient.

) does not need to be specifically occluded. Furthermore, although the mounting angle 10 is used as a mounting member to close the notch 16, for example, when the blower 6 is mounted through a vibration-proof rubber, the vibration-proof rubber may be used. Any member used for attachment may be used.

The present invention has the above-mentioned configuration, but in the past, as shown in FIG.
20, and the notch 16 was left as it was, so air leaked from the notch 16, resulting in a decrease in air blowing efficiency, and the lead wire 17 was inside the notch 16 and floated up. There was a drawback that the fan 8 would come into contact with the fan 8 due to the loose movement.

However, according to the present invention, it is possible to prevent air from leaking from the notch and achieve the desired high air blowing efficiency, and at the same time to suppress the lead wire from floating and reliably prevent it from coming into contact with the fan. This method is extremely advantageous because it uses a mounting member used for mounting the motor without using any special parts.
