DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a vacuum cleaner. More specifically, the present invention relates to an upright type vacuum cleaner in which a main body is connected to a floor suction tool so that it can be turned upside down.

[0002]

2. Description of the Related Art Conventionally, there is an upright type vacuum cleaner in which a main body accommodating a motor and a dust collecting chamber is connected to a floor suction tool so as to be able to move up and down. In such an upright type vacuum cleaner, cleaning is performed while performing a manual operation such as rotating the main body or swinging the main body in the front-rear direction while holding a handle formed on the upper part of the main body with a hand.

[0003]

However, in the conventional upright type vacuum cleaner, since the motor and the dust collecting chamber are provided in the main body, it is difficult to reduce the size and weight of the main body. In addition, since the main body is relatively large, it has a bad appearance and gives a heavy feeling.

Further, in a conventional upright type vacuum cleaner, a relatively heavy portion (so-called heavy object) such as a motor, a dust collection chamber or a cord reel is arranged at a high portion (upper portion) of a main body. At the time of actual use such as cleaning, the hand load (the load felt at the handle portion) was heavy, and the structure was difficult to operate.

Therefore, the present inventors have invented a vacuum cleaner in which a dust collecting chamber is formed inside a floor suction tool in order to reduce the size and weight of the main body. In such a vacuum cleaner, it is necessary to provide a lid for opening and closing the dust collection chamber in order to replace the dust collection bag. The lid is optimally provided on the suction tool upper surface in view of the work of replacing the dust bag. Further, the lid is attached so as to be swingable rearward (or forward) so that the dust collecting chamber can be exposed in the traveling direction of the suction tool, that is, forward (or rearward), and the front (or rear) side of the lid is mounted. Is provided with an engagement claw for engaging with the floor suction tool.

However, since the engaging claw is provided on the front side (or the rear side) of the lid, when the suction tool is inserted into a low space such as under the bed during actual use, the lid is not placed on the bed. There is a possibility that the engagement of the engaging claw with the suction tool is released by colliding with an obstacle such as, and the lid comes off. Also, the lid may be detached by a collision in the front-rear direction of the suction tool that occurs when the front surface of the suction tool collides with a wall or a step.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a vacuum cleaner in which the size and weight of the main body are reduced and the lid of the dust collection chamber is hardly detached.

[0008]

The vacuum cleaner of the present invention comprises:
What is claimed is: 1. A vacuum cleaner comprising: a floor suction device; and a main body having a motor built therein, which is connected to the floor suction device so that the floor suction device can be turned upside down, wherein a dust collection chamber is formed inside the floor suction device. A lid for opening and closing the dust collection chamber is provided on an upper surface of the floor suction tool, and the lid includes an engagement claw for engaging with the floor suction tool; Characterized in that it is provided on a side substantially parallel to the direction of travel of the suction tool.

It is preferable that a handle for opening the lid is provided so as to protrude from a side of the lid substantially parallel to a traveling direction of the floor suction tool toward a width direction of the suction tool.
