Description

  The present invention relates to an electric vacuum cleaner, and more particularly to an electric vacuum cleaner in which a storage case equipped with a dust collection pack can be attached to and detached from a dust collection chamber.

2. Description of the Related Art There is known a vacuum cleaner in which a dust collection pack is detachable in a dust collection chamber formed inside a main casing of the vacuum cleaner. However, when the dust collection pack is full of dust and inflated, it is difficult to take out the dust collection chamber.
Therefore, the dust collection pack is attached to the storage case, and the storage case is stored in the dust collection chamber. A vacuum cleaner has been proposed (see, for example, Patent Document 1).

JP 2000-70194 A

The storage case is provided with a handle that is gripped by the user to facilitate removal from the dust collection chamber.
Since the handle is erected directly from the storage case, it has to be formed small in the space of the dust collection chamber. For this reason, the handle may be difficult to grasp.

  In addition, a vacuum cleaner has been proposed in which the handle of the storage case is tilted with the lid closed, but it remains tilted when the lid is opened, and the user raises the handle himself. I had to grab it.

  An object of the present invention is to provide an electric vacuum cleaner having a dust collection pack storage case that can be attached to and detached from a dust collection chamber, and a handle of the storage case that can be tilted.
