Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having a structure in which a hose, an extension pipe, a floor nozzle and the like are connected to a main body of the electric vacuum cleaner.

[0002]

2. Description of the Related Art Conventionally, electric vacuum cleaners of this type are disclosed in Japanese Patent Publication No.
The configuration shown in Japanese Patent Publication No.-4683 is common.

A description will be given below with reference to FIG. In the figure, reference numeral 21 is a main body of the electric vacuum cleaner in which a dust collection chamber 22, a motor 23 and the like are arranged. Reference numeral 24 denotes an intake port provided in the electric vacuum cleaner body 21 in front of the dust collection chamber 22 and connected to the connection pipe 26 of the hose 25. A handle 27 to be gripped by a user is formed at the tip of the hose 25, an extension pipe 28 is connected to the tip thereof, and a floor nozzle 30 is connected to the tip of the extension pipe 28 via a floor nozzle pipe 29. .

A lid 3 that can be opened and closed is provided on the upper portion of the dust collection chamber 22.
1 is provided. At the rear of the electric vacuum cleaner body 21, a rest portion 32 and rollers 33 for moving left and right are provided, and the structure is such that the electric vacuum cleaner body 21 can be stored upright.
Furthermore, the extension pipe 28 also has a convex engaging portion A34.
Thus, the electric vacuum cleaner main body 21 can be housed by being locked by the engaging portion B35 having a concave shape.

Further, recently, as a simpler form of storage, there is a structure in which the vacuum cleaner body 21 is stored without standing upright. As shown in FIG. 10, a concave shape is formed on a side portion or a rear portion of the vacuum cleaner body 21. There is also one in which the engaging portion B35 having the convex portion is disposed and the engaging portion A34 having the convex shape disposed in the floor nozzle pipe 29 is locked and stored.

[0006]

However, in the above-mentioned conventional structure, the operation of the vacuum cleaner is interrupted every time it is necessary to move or clean up the object during cleaning, and the hose and extension pipe are placed on the floor. I feel inconvenience. In addition, even if the engaging part is locked to the side or rear part of the vacuum cleaner main body to put it in the stored state during cleaning, the weight of the hose and handle part is added as a bending moment because the support part is in the low position. If stability is poor and force is applied to the handle part, the engaging part is easily broken, and if it is broken, it can not be used as a vacuum cleaner and repair requires a lot of cost and labor. I have a problem.

[0007] The present invention solves such problems, and an object thereof is to provide an electric vacuum cleaner with improved usability.

[0008]

In order to solve this problem, the first means of the present invention is to dispose a locking portion integrally with an extension pipe and detachably lock to the locking portion. A support having a slightly inclined engaging portion is detachably attached to the connection pipe or the extension pipe with a screw or the like.

The second means is to open the engaging portion in the vertical direction and to make the length of the engaging portion longer than the length of the engaging portion.

The third means is that the fitting portion of the engaging portion and the engaging portion is formed into a substantially V shape and the fitting length is longer than the fitting width.

[0011]

According to the first means of the present invention, when it is necessary to move or clean up an object during cleaning, the hose is inserted by inserting the engaging portion provided on the extension pipe into the engaging portion attached to the connection pipe. The extension pipe can be stored while standing up, and the troublesomeness of placing a hose on the floor is eliminated and usability can be improved. In addition, the engaging part is slightly tilted forward so that the center of gravity of the hose or handle is vertically above the support part, and the stability is good, and even if the fitting part breaks due to excessive force For use, it is sufficient to replace only the support provided with the engaging part,
It can be repaired at low cost. Also, the support body provided with the engaging portion is attached to the extension pipe, a part of the support body is locked to the vacuum cleaner body, and the locking portion of the other extension pipe is locked to the engaging portion. It also has excellent stability when stored.

According to the second means, the size of the cleaner main body is increased because the engaging portion is opened in the vertical direction and the length of the engaging portion is longer than the engaging portion length. It can be used even when the supporting position differs depending on the size of the floor nozzle, etc., and expands the range of use.

According to the third means, the fitting portions of the engaging portion and the engaging portion are substantially V-shaped, and the length of the fitting portion is made longer than the width of the fitting portion. It is possible to eliminate rattling in the fitted state and to obtain more stability. Further, when an excessive force is applied, slippage occurs on the slope of the engagement portion and the slippage occurs, so that the support is not damaged.
