Description

[Detailed description of the invention] [Industrial application field] The invention relates to a vacuum cleaner which can be used as a floor moving type and as an upright type.

[Prior Art] Conventionally, there are two types of vacuum cleaners: a floor moving type in which the suction opening body and the cleaner main body move separately, and an upright type in which the suction opening body and the cleaner main body move integrally. , Respectively, depending on the purpose of use.

Since the floor moving type can move only the suction opening body, it can be inserted into a gap and is suitable for cleaning a room with many furniture and the like. On the other hand, in the upright type, the cleaner body is not dragged behind the suction port body, and there is no trouble in use. Further, since the suction opening body and the cleaner body are connected in advance, the labor for preparation can be omitted.

By the way, there is known an electric vacuum cleaner which can be used as a floor moving type or an upright type depending on the purpose by using one electric vacuum cleaner.

In the vacuum cleaner 1 shown in FIG. 5, the extension tube 3 is movably inserted into a holding portion 2a serving also as a handle protruding from the upper surface of the cleaner body 2, and the extension tube 3 is attached to the holding portion 2a. Can be locked at an arbitrary position and detached.
Therefore, the extension tube 3 is advanced from the holding portion 2a, and the cleaner body 2 and the extension tube 3 are tilted toward the front wheel 4 so that the holding portion 2a
, The suction port body 5 can be brought into contact with the floor surface F, and the cleaner body 2 and the suction port body 5 can be used as an integrated upright type. on the other hand,
By detaching the extension pipes 3 from the holding portion 2a, each can be moved separately, and the cleaner main body 2 and the suction port 5 can be used as a separate floor moving type.

[Problem to be Solved by the Invention] However, the holding portion 2a is formed on the upper surface of the cleaner body 2 also as a handle, and there is a problem that the function as the handle is impaired. Further, since the holding portion 2a has a function of locking the extension tube 3 at an arbitrary position, it is difficult to smoothly move the extension tube 3 and it is difficult to use the extension tube 3 as an upright type. There was also.

The present invention has been made in view of the above-mentioned problems, and its purpose is to improve the appearance and to not impair the function as a handle, and to be used as an upright type. An object of the present invention is to provide an easy-to-use upright type and floor moving type vacuum cleaner.

[Means for Solving the Problems] In order to achieve the above object, a main body moving wheel is provided at a rear portion of the cleaner main body, and the suction body having the moving wheel on the cleaner main body includes an extension pipe and a dust collecting hose. The extension pipe is connected to the suction pipe and the extension pipe is vertically rotatable with respect to the suction port body. A locked part to be locked is formed on a bottom surface of the cleaner body, and a rear surface of the cleaner body is placed on the suction opening body in a state where the locked part is locked to the locking part. The center of rotation of the extension pipe with respect to the suction port body is arranged to coincide with the axis of the main body moving wheel provided on the rear surface of the cleaner body, and the moving wheel of the suction port body and the main body moving wheel And grounding the surface to be cleaned at the same time That.

[Operation] In the vacuum cleaner according to the present invention, the rear surface of the cleaner main body is disposed above the suction opening body, and the locking portion provided on the extension pipe is locked to the locked portion on the bottom surface of the cleaner main body. In this state, the rotation center of the extension pipe is aligned with the axis of the main body moving wheel provided on the rear surface of the cleaner body, and the moving wheel of the suction port body and the main body moving wheel are simultaneously grounded to the surface to be cleaned. Since the weight of the cleaner body is not applied to the suction port body during use, cleaning can be performed without changing the operability when using the suction port body alone.

[Example] Hereinafter, an example of a vacuum cleaner according to the present invention will be described with reference to the drawings.

The vacuum cleaner 10 shown in FIG. 1 to FIG.
, A suction hose 12 connected to the cleaner body 11, an extension pipe 13 connected to the suction hose 12, and a suction port 14 connected to the extension pipe 13.
