Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner, and more particularly, to an improvement in appearance, usability, and reduction of mold processing cost.

[0002]

2. Description of the Related Art A conventional vacuum cleaner will be described with reference to FIGS.

[0003] In an electric vacuum cleaner in which an electric blower 2 and a dust collecting chamber 3 communicating with the electric blower 2 are contained inside a main body 1, one end of the main body 1 is pivotally supported at one end. A cover 4 that is rotatable and covers the dust collection chamber 3 so as to be openable and closable is provided, and a handle portion or a hand hole 5 for opening the cover 4 is provided in front of the cover 4. One end is pivotally supported at the upper part and is rotatable in the front-rear direction.
A handle 6 for carrying the main body by turning it upward is arranged, and the lid 4 and the handle 6 turn independently of each other.

[0004]

In such a conventional vacuum cleaner, a handle portion or a hand hole 5 for opening a cover 4 for covering the dust collecting chamber 3 is formed on an external portion of the cover 4. Because of the necessity, the external appearance is impaired, and there is a problem that mold processing is complicated and costly.

[0005] In addition, since only a small grip portion or hand hole small enough for a finger to be formed can be formed, the usability is poor.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and has as its object to improve the appearance of a vacuum cleaner, improve usability, and reduce mold processing costs.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an electric blower, a main body including a dust collecting chamber communicating with the electric blower, and a rotatably supported pivot on an upper portion of the main body. A lid for opening and closing the dust collecting chamber, and a handle rotatably supported on the upper part of the main body and rotatably supported for carrying the main body, wherein the rotation of the handle and the opening / closing operation of the lid are linked. Therefore, the lid can be opened by operating a large handle for carrying the main body, so that usability is improved, and further, it is not necessary to provide a handle portion or a hand hole for opening and closing the lid, so that the appearance is improved. In addition, the mold processing cost can be reduced.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION
An electric blower, a main body including a dust collecting chamber communicating with the electric blower, a lid rotatably supported at an upper portion of the main body to open and close the dust collecting chamber, and a rotatable upper part of the main body. A handle is pivotally supported on the main body, and a handle for carrying the main body is arranged, and the rotation of the handle and the opening and closing operation of the lid are linked, and the lid can be opened by operating a large handle for carrying the main body. Therefore, the usability is improved, and it is not necessary to provide a handle portion or a hand hole for opening and closing the lid, so that the appearance can be improved and the die processing cost can be reduced.

According to a second aspect of the present invention, there is provided a vacuum cleaner according to the first aspect, wherein the cover is opened when the handle is rotated further forward or backward from a substantially upright position when the main body is carried. The lid is not opened when the main body is carried, and the lid can be opened by rotating the handle further than a substantially upright position when the main body is carried, thereby improving usability.

According to a third aspect of the present invention, the bearing hole of the rotating shaft of the handle for carrying the main body is made oblong, and when the main body is carried using the handle, the handle moves upward due to the weight of the main body. The vacuum cleaner according to claim 1, wherein when the handle is moved upward, the lid that covers the dust collection chamber and the handle are not in contact with each other. Since the handle does not abut, the lid does not accidentally open due to swinging back and forth of the main body when carrying the main body.

[0011]

(Embodiment 1) First and second embodiments of the present invention will be described below with reference to FIGS.

In a vacuum cleaner in which an electric blower 2 and a dust collecting chamber 3 communicating with the electric blower 2 are contained inside a main body 1, one end is attached to a rotating shaft 1a provided on the upper part of the main body 1. A lid 4 that is supported and is rotatable in the front-rear direction and that covers the dust collection chamber 3 so as to be openable and closable is provided. A handle 6 is provided, a first engaging portion 7 is provided on the lid 4 as shown in FIG. 3A, and a second engaging portion 8 is provided on the handle 6 as shown in FIG.
When the handle 6 is rotated to a substantially upright position when the main body is carried as in (B), the first engagement portion 7 and the second engagement portion 8 are prevented from coming into contact with each other. When the handle 6 is further rotated than the position at the time of carrying the main body as shown in FIG. 5 (in the rear direction of the main body 1 in the figure), the first engagement portion 7 and the second engagement portion 8 The lid 4 is brought into contact with the lid 4 and opened.

The operation of the above configuration is as follows.
By operating the large handle 6 for carrying the main body, the lid 4 can be opened, so that the usability is improved, and the lid 4 does not need to be provided with a handle for opening and closing or a hand hole, so that the appearance is improved. It is possible to improve and reduce the mold processing cost.

(Embodiment 2) Hereinafter, a third embodiment of the present invention will be described with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

As shown in FIG. 6A, the bearing hole 10 of the handle 6 which engages with the rotating shaft 9 is formed into an oblong shape, and when the main body 1 is carried using the handle 6, the main body as shown in FIG. The handle 6 is moved upward by its own weight so that the first engagement portion 7 and the second engagement portion 8 do not come into contact with each other when the main body 1 is carried as shown in FIG. 7B. .

The operation of the above configuration is as follows.
Since the cover 4 and the handle 6 do not abut when the main body 1 is carried, the lid 4 does not accidentally open due to the back and forth swing of the main body 1 when the main body 1 is carried.

[0017]

According to the first aspect of the present invention,
Usability is improved because the lid can be opened by operating the large handle for carrying the main body by interlocking the rotation of the handle for carrying the main body and the opening and closing operation of the lid covering the dust collection chamber, thereby improving the usability. Further, since it is not necessary to provide a handle portion or a hand hole for opening and closing the lid, the appearance can be improved and the mold processing cost can be reduced.

According to the second aspect of the present invention, the cover is opened when the handle is further rotated forward or backward from the substantially upright position when the main body is carried, so that the main body is carried when the main body is carried. Since the lid can be opened by opening the lid further than the substantially upright position when carrying the main body without opening the lid, the usability is improved.

According to the invention of claim 3 of the present invention, the bearing hole of the rotating shaft of the handle for carrying the main body is made oblong, and when the main body is carried using the handle, the handle is lifted by its own weight. To prevent the lid from coming into contact with the handle so that the lid does not accidentally open due to the back and forth swing of the main body when carrying the main body.
