JPH04285517A - Upright type electric vacuum cleaner - Google Patents

Abstract

PURPOSE:To enable winding of a cord when a cleaner is housed by pushedly housing the handle, and to enable the winding operation of the cord to be easily carried out even in the case a cord reel is provided at the lower part of the cleaner body. CONSTITUTION:An upright type electric cleaner is constituted in such a way that an operation part 15 is formed in the pipe part 9 of a handle 8 that has been slidably fitted to the cleaner body 1 in which a cord reel 5 is incorporated, and when the handle 8 is housed by pressing it downward, the operation part 15 pushes the other end of the brake operator of a cord winding mechanism 11 to turn the brake operator around a fulcrum 12, so that the control roller 14 of the brake operator is separated from the outer circumference of the cord reel 5 to release the rotating regulation of the cord reel 5.

The present invention is characterized in that the cord reel is provided with a handle that is attached to the handle and has a pipe portion, and that the pipe portion is provided with an operating body that operates the cord winding mechanism of the cord reel when the handle is pressed downward.

The present invention also provides a vacuum cleaner body having a dust collection chamber, an air suction section, an electric blower, and a cord reel, a suction tool attached in communication with the air suction section of the vacuum cleaner body, and one end connected to the vacuum cleaner body. a bellows hose that communicates with the dust collection chamber of the main body and whose other end is detachably connected to the suction section; a handle attached to the vacuum cleaner main body; an attachment attached to the other end of the bellows hose; and the cleaner. an attachment holding part formed on the vacuum cleaner body to detachably and slidably hold the attachment; the attachment holding part is operated by the attachment to move the attachment to the sliding position of the vacuum cleaner main body, and the cord winding portion of the cord reel is operated by the attachment; It is characterized by the provision of a cord winding button to operate the mechanism.

[0006]

According to the first aspect of the present invention, when the handle is pressed downward, the operating body formed on the pipe portion operates the cord winding mechanism of the cord reel, and the cord is wound up.

According to the second aspect of the present invention, when the attachment detachably housed in the vacuum cleaner body is pushed down, the attachment operates the cord winding mechanism of the cord reel, and the cord is wound up.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

1 is a vacuum cleaner body, and inside the vacuum cleaner body 1,
A dust collection chamber 2, an electric blower 3, and a cord reel 5 biased in a direction to wind up a cord 4 are arranged in this order from above. Reference numeral 6 denotes a suction section formed at the bottom of the vacuum cleaner main body 1, to which a bellows hose 10, which will be described later, is connected and a suction tool 7 is attached. Reference numeral 8 denotes a handle having a pipe portion 9, which is slidably attached to the back surface of the vacuum cleaner main body 1. When cleaning, the handle 8 is pulled out and used, and when storing the vacuum cleaner, the handle 8 is slidably attached. is the handle 8
Press down to store. Reference numeral 10 denotes a bellows hose, one end of which communicates with the dust collection chamber 2 of the vacuum cleaner main body 1, and the other end of which is detachably connected to the air intake section 6.

Reference numeral 11 denotes a cord winding mechanism for releasing the rotation restriction of the cord reel 5, which includes a brake operating body 13 rotatable about a fulcrum 12, and a cord winding mechanism rotatably attached to one end of the brake operating body 13. The brake roller 14 is biased by an elastic body (not shown) in the direction of contacting the outer periphery of the cord reel 5, and the brake roller 14 is brought into contact with the outer periphery of the cord reel 5. It is designed to stop rotating.

Reference numeral 15 denotes a protrusion which is an operating body formed on the pipe portion 9 of the handle 8. When the handle 8 is pushed downward and stored, the other end of the brake operating body 13 is pressed and the brake is activated. The operating body 13 is rotated, and the braking roller 14 moves away from the cord reel 5 to wind up the cord 4.

[0012] When cleaning, the handle 8 is pulled upward and the cord 4 is pulled out and used. When storing the vacuum cleaner main body 1, the handle 8 is pressed downward and stored. At this time, the protrusion 15 provided on the pipe portion 9 of the handle 8 is connected to the brake operating body 13 of the cord reel 5.
is pressed to rotate the brake operating body 13, the brake roller 14 of the brake operating body 13 is separated from the outer periphery of the cord reel 5, the brake is released, and the cord 4 is wound up.

Therefore, the cord winding mechanism 11 of the cord reel 5 located below the vacuum cleaner main body 1 can be easily operated without bending down, and the operability can be improved.

A second embodiment of the present invention will be explained based on FIGS. 4 to 8. Incidentally, the same parts as in the first embodiment are given the same reference numerals and the explanation thereof will be omitted.

Reference numeral 16 denotes a gap attachment that is detachably attached to the other end of the bellows hose 10 that has been removed from the air intake section 6. When not in use, the attachment holding section 17 formed on the back of the vacuum cleaner main body 1 allows It is detachably and slidably held on the vacuum cleaner main body 1. Reference numeral 18 denotes a cord winding button, which causes the operation part 19 to project to the sliding position of the gap attachment 16 on the back side of the vacuum cleaner main body 1, and has a cord winding button inside the vacuum cleaner main body 1.
A pressing part 20 is formed that comes into contact with the brake operating body 13, and by pushing down the operating part 19, the pressing part 20 presses the end of the brake operating body 13 in the forward direction.

Reference numeral 21 denotes a fitting body formed at the rear of the suction tool 7, and has a fitting part 22 into which the tip of the pipe part 9 fits when the handle 8 is pressed and stored.

[0017] When winding up the cord 4, for example when storing a vacuum cleaner, the gap attachment 16 is used.
is pushed down, and the operating portion 19 of the cord winding button 18 is pushed down by the tip of the gap attachment 16. As a result, the pressing portion 20 of the cord winding button 18
rotates the brake operating body 13, and the brake operating body 13
The braking roller 14 is separated from the outer periphery of the cord reel 5, the cord reel 5 rotates, and the cord 4 is wound up.

Furthermore, the tip of the pipe portion 9 of the handle 8 is
By fitting into the fitting part 22 of the fitting body 21, the pipe part 9 is prevented from coming into contact with the floor surface and damaging the floor surface when the handle 8 is pressed and stored. In addition, even if a force is applied to the vacuum cleaner body 1 in a direction that twists the suction tool 7 due to hitting the handle 8 in the stored state, the tip of the pipe portion 9 will not fit into the fitting portion 22. Twisting of the cleaner body 1 is restricted, and the load on the connecting pipe (not shown) connecting the suction section 6 and the suction tool 7 is reduced, so there is no risk of the connecting pipe being damaged.

[0019]

According to the structure of claim 1 of the present invention, when storing the vacuum cleaner, the cord can be wound up by pressing and storing the handle, even when the cord reel is located below the main body of the vacuum cleaner. You can easily wind the cord.

Furthermore, according to the structure of claim 2 of the present invention,
When winding up the cord, such as when storing the vacuum cleaner, the cord is rolled up by pressing down on the gap attachment, making it possible to wind up the cord with a simple action.
