Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vacuum cleaner, and more particularly to appearance of the vacuum cleaner, improvement of usability, and reduction of mold processing costs.
[0002]
[Prior art]
A conventional vacuum cleaner will be described with reference to FIGS.
[0003]
In a vacuum cleaner in which an electric blower 2 and a dust collection chamber 3 communicating with the electric blower 2 are contained inside the main body 1, one end is pivotally supported on the upper portion of the main body 1 and can be rotated in the front-rear direction. In addition, a lid 4 that covers the dust collection chamber 3 so as to be openable and closable is disposed. A handle portion or a hand hole 5 for opening the lid 4 is provided in front of the lid 4. One end is pivotally supported, and the handle 6 can be rotated in the front-rear direction and rotated to the upper side of the main body 1 to carry the main body. The lid 4 and the handle 6 rotate independently of each other. The configuration was as follows.
[0004]
[Problems to be solved by the invention]
In such a conventional vacuum cleaner, it is necessary to form a handle portion or a hand hole 5 for opening the lid 4 covering the dust collecting chamber 3 in the external portion of the lid 4, so that the appearance of the appearance is impaired. Furthermore, there is a problem that the die processing is complicated and costly.
[0005]
In addition, because of the design, only a handle portion or a hand hole small enough to fit a finger could be formed, and the usability was poor.
[0006]
The present invention is intended to solve the above-described conventional problems, and aims to improve the appearance of a vacuum cleaner, improve usability, and reduce mold processing costs.
[0007]
[Means for Solving the Problems]
To achieve the above object, the present invention provides an electric blower, a main body including a dust collection chamber communicating with the electric blower, and a lid that pivotally supports the upper portion of the main body to open and close the dust collection chamber. A handle that is also pivotally supported on the upper portion of the main body and is used for carrying the main body , a first engagement portion provided on the lid, and a second engagement portion provided on the handle the provided, in conjunction with opening and closing operation of said the rotation of the handle cover, when the handle is rotated to a substantially upright position when the body carrying said a first engagement portion and second engagement portion When the handle is further rotated from the substantially upright position when the main body is carried, the first engaging portion and the second engaging portion come into contact with each other, and the lid in which it is to open and can be opened the lid by operating a large handle for body carrying Improved usability, those which can further handle part or is not necessary because the provision Teana improve appearance of appearance and the reduction of the die processing cost for closing the lid. In addition, the lid is not opened when the main body is carried, and the lid can be opened by rotating the handle further than the substantially upright position when carrying the main body, so that the usability is improved.

DETAILED DESCRIPTION OF THE INVENTION
The invention according to claim 1 of the present invention includes an electric blower, a main body including a dust collection chamber communicating with the electric blower, and a lid pivotally supported on the upper portion of the main body to open and close the dust collection chamber. A handle that is also pivotally supported on the upper portion of the main body and is used for carrying the main body , a first engagement portion provided on the lid, and a second engagement portion provided on the handle the provided, in conjunction with opening and closing operation of said the rotation of the handle cover, when the handle is rotated to a substantially upright position when the body carrying said a first engagement portion and second engagement portion When the handle is further rotated from the substantially upright position when the main body is carried, the first engaging portion and the second engaging portion come into contact with each other, and the lid in which it is to open, use it is possible to open the lid by operating a large handle for body carrying Sex is improved, it is more grip or is not necessary because the provision Teana improve appearance of appearance and the reduction of the die processing cost for closing the lid. In addition, the lid is not opened when the main body is carried, and the lid can be opened by rotating the handle further than the substantially upright position when carrying the main body, so that the usability is improved.

【Example】
Example 1
Hereinafter, first and second embodiments of the present invention will be described with reference to FIGS.
[0010]
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 the main body 1, one end is pivotally supported by a rotating shaft 1 a provided on the upper portion of the main body 1. A lid 4 that can rotate in the direction and covers the dust collecting chamber 3 so as to be openable and closable is disposed, and a handle 6 for carrying the main body whose one end is pivotally supported in the front-rear direction of the main body on the rotation shaft 1a. 3A, the lid 4 is provided with a first engaging portion 7, the handle 6 is provided with a second engaging portion 8, and the handle 6 is provided as shown in FIG. 3B. When the main body is rotated to a substantially upright position when the main body is carried, the first engaging portion 7 and the second engaging portion 8 are prevented from coming into contact with each other. When it is further rotated from the carrying position (in the rear direction of the main body 1 in the figure), the first engaging portion 7 and the second engaging portion 8 come into contact with each other and the lid To have such open configuration.
[0011]
The operation of the above configuration is as follows.
[0012]
Since the lid 4 can be opened by operating a large handle 6 for carrying the main body, the usability is improved, and it is not necessary to provide a handle portion or a hand hole for opening and closing the lid 4, so that the appearance is good. Improve and reduce mold processing costs.
[0013]
(Example 2)
A third embodiment of the present invention will be described below with reference to FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0014]
The bearing hole 10 of the handle 6 that engages with the rotating shaft 9 is made into an oval shape as shown in FIG. 6A, and when the main body 1 is carried using the handle 6, the weight of the main body 1 as shown in FIG. Thus, the handle 6 is moved upward so that the first engaging portion 7 and the second engaging portion 8 do not come into contact with each other as shown in FIG.
[0015]
The operation of the above configuration is as follows.
[0016]
Since the lid 4 and the handle 6 do not come into contact with each other when the main body 1 is carried, the lid 4 will not be accidentally opened due to shaking of the main body 1 when carrying the main body 1.
[0017]
【The invention's effect】
By the present invention lever, so that you can open the lid by operating a large handle for body carrying by interlocking the opening and closing operation of the lid for covering the rotating and the dust collecting chamber of the handle for body carrying Therefore, usability is improved, and it is not necessary to provide an opening / closing handle portion or a hand hole in the lid, so that the appearance can be improved and the die processing cost can be reduced.
[0018]
In addition , when the handle is rotated further forward or backward than the substantially upright position when carrying the main body, the lid is opened so that the lid does not open when the main body is carried, and the handle is substantially upright when carrying the main body. Since the lid can be opened by further rotating than the position, usability is improved.
