Description

[Detailed Description of the Invention] The present invention relates to a blower with an improved power cord drawer locking structure.

Conventionally, as a locking structure for a power cord in a blower, there is one described in Japanese Utility Model Publication No. 53-52075.

The cord described in this publication stores the knot of the cord in the cylindrical body to prevent the cord from being pulled out, but this does not prevent the cord from being pulled out when the cord is pulled in the direction toward the opening of the cylindrical body.

In view of the above points, it is an object of the present invention to provide a blower that can be securely held regardless of the direction in which the power cord is pulled.

In order to achieve the above-mentioned purpose, this proposal forms a motor mounting part supported by a support bar in the center of a cylindrical opening formed in the blower body, and connects a power cord knot to the outside of the opening near the support bar. A companion part to be inserted is formed, a wind tunnel having an edge abutting the opening is formed in the cover covering the inner surface of the main body, and an edge is close to the opening of the box part on the outside of the wind tunnel. By forming a ring to prevent the knot from being pulled out, the knot is constructed in the same state as if it were stored in a box with no opening.

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes a box-shaped blower, which is divided into front and rear parts and consists of a blower main body 2 equipped with a motor and the like, and a cover 3 that covers the inner surface of the main body.

A substantially cylindrical opening 4 is formed in the main body 2, and a mounting portion 6 for the motor 5 is mounted at the center of the opening 4 through a number of support bars 7.
... are connected and formed.

The motor 5 is housed in a recess 8 formed on the rear surface of the mounting portion 6, and the flange 9 of the motor is fixed at several locations with screws 10.

A mounting nut 1 is attached to the rotating shaft 11 protruding from the motor 5.
At 2, the blade 13 is fixed.

Further, an annular rib 14 is provided protruding from the front surface of the mounting portion 6,
A rotating shaft 17 for fixing the rotating shaft portion 16 of the looper 15 protrudes within the space surrounded by the ribs 14, and the rotation speed for controlling the speed at which the looper 15 rotates by the wind blown by the blades 13 is reduced. A case body 18 is installed in which a group of gears meshed with the shaft 1T are inserted.

The looper 15 rotates to send wind over a wide range, and the wind direction plate 19 changes its angle little by little.
It is equipped with...

A groove 21 is formed in one of the support bars γ extending upwardly, through which the power supply cord 20 to the motor is inserted.

Bosses 22.22 for fastening to the cover 3 are formed above and below the opening 4 of the main body 2 and at the base end of the support bar 7.7.

A switch 24, a timer 25, etc. are mounted on the outer peripheral wall of the main body 2, that is, the upper wall 23, and a pair of engaging recesses 26 are formed in a portion of the back surface of the upper wall 23.

Further, a pair of claw pieces 28 are provided protruding from the tip of the lower wall 27 of the main body 2, and the claw pieces 28 are engaged with an engagement hole 29 provided on the cover 3 side.

30 extends longer than the claw piece 28, and has an elastic leg 31 made of rubber or the like for supporting the main body attached to the tip.

A support leg 32 that can be raised freely is provided at the front of the outer surface of the lower wall 27.
The iron legs can be held either in the raised state or in the collapsed state as appropriate.

A mating portion 35 is formed outside the opening 4 near the boss 22 to accommodate a knot 34 of a power cord 33 wired along the outside of the opening.

At several locations near the outside of the opening 4 are projecting pins 36, 36, . . . for holding the power cord 33 along the outside.

Therefore, the power supply cord 20 is connected to the switch 24 and the timer 25, and the power cord 33, which has one end connected to the switch 24 and the timer 25, is connected to the pin 36.
After the knot 34 is held and wired between the pin 36 and the outside of the opening 4, and the knot 34 is housed in the phase portion through the notch 37 formed in the phase portion 35, another notch in the phase portion 35 is inserted. The power cord 33 is pulled out from the assembly part 38.

A trumpet-shaped wind tunnel 39 is formed in the cover 3 so as to cover the circumference I of the blade 13.

Of the outer circumferential wall of the cover 3, an upper wall 40 is provided with a pair of L-shaped hook pieces 41 that engage with the engagement recess 26 on the main body side.

The cover 3 connects the cursor-shaped hook piece 41 to the engagement recess 2.
6 and when the lower part of the cover 3 is circuited using this hooking point as a fulcrum, the claw piece 28 on the lower wall of the main body engages with the engagement hole 2.
9, and the main body 2 and cover 3 overlap.

When overlapped as described above, the edge of the wind tunnel 39 comes into contact with the four edges of the opening of the main body.

A tongue piece 40 that abuts the one boss 22 and a lid piece 41 that abuts the other boss 22 and closes the groove 21 are provided on the edge of the wind tunnel 39.
At step 2.42, attach the tongue piece 40 and lid piece 41 to the boss 22.22.
The main body 2 and the cover 3 are fixed to each other so that the main body 2 and the cover 3 are completely overlapped with each other.

The free end edge of the lid piece 41 is engaged with the flange 9 of the motor using its elasticity.

The outer surface of the wind tunnel 39 is formed with a vertical rib 43 whose edge is located close to the opening of the phase part 35, so that when the power cord 33 is pulled, the knot 34 is connected to the phase part 3.
5 to prevent it from being pulled out.

In this embodiment, the rib 43 and the tongue piece 40 fixed by the screw 42 are arranged close to each other, so that when the power cord 33 is pulled, the rib 43 connects to the knot 3.
4, the wind tunnel 39 does not bend even when pressed at
It is something that will be maintained reliably.

Further, the end edge of the vertical rib 43 is cut into the notch 38 of the phase portion 35.
By inserting the power cord 33 inside the power cord 33, the power cord 33 can be held even more reliably.

The power cord 33 is pulled out from the cover through a cord pull-out opening 44 formed on the rear surface of the cover 3.

A guard 46 is detachably attached to the rear opening 45 of the cover of the wind tunnel 39.

A U-shaped frame-shaped handle 47 is attached to the upper rear surface of the cover 3 using the screw 4.
It is fixed at 8.

A pair of L-shaped cord hooks 49 are formed at the lower part of the rear surface and are bent outward, and the power cord 33 pulled out from the cover 3 is looped around the double-folded hooks 49. is retained.

As described above, the present invention has a motor mounting part supported by a support bar in the center of a cylindrical opening formed in the blower body, and a matching part into which a power cord knot is inserted outside the opening near the support bar. A wind tunnel is formed in the cover that covers the inner surface of the main body, the edge of which contacts the opening, and outside of the wind tunnel, the edge is close to the partner opening and the knot is pulled out. It has a rib that acts as a stopper, and the power cord can be securely held by simply inserting the knot of the power cord into the phase part and attaching the cover to the main body, and the structure is simple. This has great practical effects.
