Description

[Detailed description of the invention] This invention relates to the improvement of vacuum cleaners, and allows for efficient cleaning work by making it possible to select the performance and dust collection capacity according to the place of use, that is, the type of dust. The purpose is to provide a vacuum cleaner that can be used.

In general, the dust targeted by vacuum cleaners can be broadly classified into fine dust and coarse fibrous dust.

In a general household, the composition ratio by volume is 15:85 of sandy dust to fibrous dust, but it is often seen that it is biased to one side depending on the place of use.

This tendency is particularly noticeable in areas where commercial vacuum cleaners are used. For example, in buildings such as hotels, urine collected from hallways and other areas is mostly sandy dust, but in areas covered with paper, on the contrary, it is carpeted. Since there are many loose hairs, most of the dust storage capacity is occupied by fibrous dust.

It goes without saying that in manufacturing factories, the composition of dust is often biased to one side depending on the product being manufactured.
If you use a conventional vacuum cleaner in such places, the filter will easily become clogged in places with a lot of sandy dust, and the dust collection capacity will be insufficient in places with a lot of fibrous dust, so you will have to empty the dust frequently. A troublesome problem arose.

Therefore, this invention aims to solve the above problems.
One embodiment of the present invention will be described below with reference to the accompanying drawings.

In Fig. 1, reference numeral 1 denotes a vacuum cleaner main body having a main body handle 2 on the upper part, and an electric blower 5 is built in through a front shock absorber 3 and a rear shock absorber 4, and the front and rear shock absorbers 3.4 are supported by support plates. 6, and this support plate 6 is attached to plate 7.

Reference numeral 8 denotes a dust box, which houses a bag-shaped filter 11 fitted with a filter frame 9 and having a mouthpiece 10 sewn thereon.

Inside this filter 11, there is a filter 11 for dust collection.
A main filter support 12 and a sub-filter support 13 are provided in order to maintain the shape of the filter.
3a is engaged with the groove 12a of the main filter support 12, so that the main filter support 12 can be detachably assembled.

A patch plate 14 is sewn to the bottom of the filter 11, and an elastic support arm formed integrally with the main filter support 12 is inserted into the hole 14a provided in the patch plate 14. 12b is fitted, and the filter 11
is detachably attached to the main filter support 12.

Furthermore, a handle 12C of the main filter support 12 is provided to be held by hand when taking out or removing dust.

15.16 are casters and rollers for movement.

In the above configuration, when using the vacuum cleaner in a place with a lot of sand and dust, if the main filter support 12 and the sub filter support 13 are combined and used, the filter 11 can be greatly expanded and retained its shape. , the effective dust collection area of the filter 11 is maximized, and therefore the filter 11 is also less likely to be clogged, and its fine dust collection performance is improved.

In addition, in places with a lot of fibrous dust, the sub filter support 1
3 is removed and the main filter support 12 is used alone, the dust collection capacity increases by the space occupied by the sub filter support 13.

In this case, the effective dust collection area of the filter 11 is
However, in the case of fibrous dust, it itself has air permeability, and in the case of sandy dust, the dust collection area of the filter determines the dust collection capacity, whereas the dust collection capacity determines the dust collection capacity. There is no problem since it will determine the dust ability.

In addition, as shown in Fig. 3, in the above configuration, by using the main filter support 12 alone and changing the dust box 8 to a small dust box 8', a small and lightweight model can be created. It has the advantage of being able to measure the development of

In this way, according to the present invention, efficient cleaning work can be performed depending on the location of use, that is, the type of dust, and at the same time, it is possible to develop a compact and lightweight model by simply changing the dust box. It has great practical value, such as the ability to diversify models.
