Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a vacuum cleaner equipped with a dust collection bag storage section at the rear of the main body case.

[Prior Art] In a conventional vacuum cleaner, as shown in FIG. 10, a mounting body 62 is provided at the front of a dust collection chamber 60, a dust collection bag 61 is mounted, and a dust collection bag 61 is mounted at the rear. A storage section 63 for storing a spare dust collection bag 61 is provided.

This storage section 63 is formed to have an inverted L-shaped cross section, and both ends of the portion disposed on the dust collection case 64 side are rotatably supported inside the dust collection case 64 by a shaft 71. A knob 66 is provided at the upper end of the portion disposed on the auxiliary filter 65 side. Therefore, the dust collection bag 61 is folded into an inverted L shape along the shape of the storage part 63, and the paper filter part 61 of the dust collection bag 61 is folded on the dust collection case 64 side.
b is housed, and a mouth plate 61a is housed on the auxiliary filter 65 side.

In such a configuration, in order to replace the dust collection bag 61 in the dust collection chamber 60, after pressing the clamp 67 and opening the lid 68, remove the dust collection bag 61 containing dirt from the opening 69. Take it out.

Next, a finger is engaged with a knob 66 provided at the upper end of the storage section 63, and the storage section 63 is rotated counterclockwise to tilt it. In this state, storage section 6
Opening plate 6 of the spare dust collection bag 61 stored in 3
1a and pull it out from the storage section 63, and then release the knob 66, the storage section 63 will rotate clockwise due to its own weight and return to its original state inside the dust collection chamber 60. Therefore, a new dust collection bag 61 is attached to the attachment body 62.

In addition, there is a case in which a storage chamber for storing spare paper bags is provided at the rear of the main body case, and this storage chamber is covered with a storage chamber lid that can be opened and closed to allow paper bags to be taken in and out. (Tokukai Akira
58-10022 Publication) [Problems to be solved by the invention] In the former type, the storage section 63 for the spare dust collection bag 61 is provided inside the dust collection case 64, so that the inside of the dust collection chamber 60 is becomes relatively small, and the storage capacity for garbage decreases. In addition, there are uneven parts inside the dust collection case 64, and since the mouth plate 61a of the spare dust collection bag 61 in the storage section 63 is placed on the airflow path, the air that has passed through the paper filter section 61b Flows from around the opening plate 61a toward the electric blower 70, which impairs the flow of the air and causes the paper filter portion 61b to bulge out poorly, and as a result,
Since the capacity for collecting dust inside the paper filter section 61b is reduced, the dust collection bag 61 must be replaced before the paper filter section 61b is full of dust, resulting in problems such as being uneconomical.

Therefore, in order to solve this problem, if the dust collection case 64 is made larger, the vacuum cleaner as a whole becomes larger and heavier, and the work efficiency deteriorates.

Also, from the outside, the storage section 63 inside the dust collection case 64
Since it is not visible, it is easy to forget when to refill the spare dust collection bag 61. Therefore, there was a problem that the dust collection bag 61 ran out when it was needed, causing trouble in the work.

Further, in the latter type, the paper bag stored in the storage chamber is not used as an exhaust filter, so a dedicated exhaust filter is required.

Furthermore, since the exhaust filters of both types are non-removable, they become dirty and unsanitary after being used for many years.

[Means for solving the problem] This invention forms a storage section along the inside of the rear wall of the main body case to store a spare dust collection bag, and a storage section for storing a spare dust collection bag stored in this storage section. The bag is folded into an L-shape with a mouth plate and a filter part, and this filter part is placed along the inside of the rear wall, so you can store a spare dust collection bag and prevent dust from being included in the exhaust air. Since the dust can be collected, there is no secondary contamination of the room due to exhaust air, and there is no need to install a filter on the exhaust side as in the past, so the number of parts can be reduced. This is how it was done.

[Function] Fine dust passing through the dust collection bag and dust such as carbon discharged from the electric blower are exhausted into the storage section along with the exhaust air. Here, fine dust contained in the exhaust air is collected by a filter section, and the resulting clean exhaust air is exhausted to the outside through an exhaust hole formed in the rear wall.
