Description

TECHNICAL FIELD The present invention relates to an electric vacuum cleaner provided with an after filter in order to further clean the air discharged from the vacuum cleaner into the room.

[Conventional technology]

As for the vacuum cleaner with an after filter,
As described in Japanese Utility Model Laid-Open No. 60-67751, a vacuum cleaner with a case with a built-in after filter attached to the exhaust port,
It is known to attach a bag-shaped filter to an exhaust port.

[Problems to be solved by the invention]

The above-mentioned conventional after filter has a problem that it is difficult to replace the filter case because it is troublesome to attach and detach the filter case, and there is a problem that it costs a lot to replace the filter.

In addition, it was a big problem to use the entire filter in reverse and to keep the hands clean when replacing the filter.

[Means for solving problems]

A feature of the present invention is that a first case and a second case each having a lower end that can be opened and closed by a hinge and a first case and a second case that are clamped and fixed between the two cases when the first case and the second case are closed. A filter for collecting dust that forms a space between them, an air inlet formed at the upper end of the first case, an air outlet formed at the lower end of the second case, and the second An after filter formed by a handle for gripping formed on the upper end of the case, and an after filter storage chamber having an opening for attaching and detaching the after filter on the upper side are formed adjacent to the air blowing chamber, and the after filter storage is formed. The chamber is separated from the blower air chamber by a partition wall, and is in close communication with the air intake formed in the first case when the after filter is stored in the after filter storage chamber. That is a passage to the electric vacuum cleaner comprising a combination of a cleaner body which is formed on the partition wall.

[Action]

According to the above configuration, the operation is completed only by handling the after filter having the filter held between the first case and the second case as one component and mounting it in the after filter storage chamber.

Therefore, it does not take time to attach and detach the filter case,
Moreover, the replacement of the filter is easy and inexpensive.

In addition, the after filter allows air to enter from the top, passes through the filter, and is then discharged to the outside from the bottom, so that the entire filter can be used effectively.In addition, when replacing the filter, the filter falls by its own weight simply by opening the case. It doesn't pollute.

〔Example〕

Embodiments of the present invention will be described with reference to the accompanying drawings. In FIG. 3, 1 is a cleaner body, 3 is a dust collecting filter, 2 is a dust collecting part, 4 is an electric blower, and 6 is a dust collecting case lid that closes the dust collecting chamber. 12 is hose 9 when not using a vacuum cleaner, extension pipe
It is a storage case that stores 10, mouthpiece 11, etc.

The dust collecting section 2 is composed of a dust collecting case 31 whose side and bottom surfaces are made of a filter material and a filter mounting base 32, and the dust collecting section 2 is connected to a suction port of the medial blower 4 by a connection flow path 35. . In the storage room 24 of the blower 4, the air flow is directed to the exhaust window 25 by the wall surface of the cleaner body 1 and the ribs 36 inside.

The after filter case 14 is connected to the exhaust window 25.

As shown in FIG. 1 and FIG. 2, the after filter case 14 is divided into two parts, a case 15 and a case 16, a lower part is connected by a hinge 18 and a shaft 17, and an upper part is a top lid 19 of the case 16. By engaging the claws on the lower surface with the projections on the upper surface of the case 15, the flat filter 23 is held by the joint between the case 15 and the case 16. A space is formed between the case and the filter. Case
An air intake window 27 that abuts an exhaust window 25 provided in the blower housing chamber 24 is provided on the front surface of the fan 15, and an air outflow slit 28 is provided on the rear surface of the case 16. 26 is a packing provided on the contact surface of the window 27. Between the rib 20 provided on the lower part of the case 15 and the bottom plate 23, the rib provided on the lower part of the case 16
A pack of deodorant or fragrance can be placed between 21 and the bottom plate 48. Reference numeral 29 is a protrusion for locking the case 16 to the rear surface plate of the main body case of the vacuum cleaner, and 30 is a handle for pulling out the case.

〔The invention's effect〕

According to the present invention, the after filter is handled as one component, and the work is completed simply by mounting it in the after filter storage chamber. Therefore, it is easy to attach and detach the filter case, and the filter can be easily replaced. It costs nothing.

In addition, the after filter allows the air to enter from above, pass through the filter, and be exhausted from the rear to the outside, so that the entire filter can be used effectively.Furthermore, when replacing the filter, simply open the case and the filter will drop under its own weight. Therefore, his hands are not soiled.
