Vacuum cleaner and dust bag for vacuum cleaner

Abstract

A vacuum cleaner includes a dust chamber (15); a dust bag (1) provided in the dust chamber (15); and an electric blower (16) for generating suction air flow for drawing and collecting dust and dirt in the dust bag (1). A deodorant (3a) is supplied into the dust bag (1) by the suction air flow and directly attached to the dust and dirt, the deodorant (3a) having a granule or powder shape.

Description

technical field [0001] The present invention relates to an electric vacuum cleaner and a dust collecting bag used in the electric vacuum cleaner, more specifically, the present invention relates to an electric vacuum cleaner capable of deodorizing the dust accumulated in the dust collecting bag and a dust collecting bag for the electric vacuum cleaner bag. Background technique [0002] In the existing method of deodorizing the dust accumulated in the dust bag of the electric vacuum cleaner, some of the dust bag and the dust filter are impregnated with a deodorant, and the peculiar smell emitted by the dust is eliminated by the deodorant. Deodorization is carried out (for one example, refer to Japanese Patent Laid-Open Publication No. Hei 5-70871). [0003] In addition, the method that also has is to set up the deodorizing aromatic agent in the dust collection chamber that dust collection bag is packed in electric vacuum cleaner (one example wherein can refer to Japanese Pat...

AI Technical Summary

Problems solved by technology

[0004] But, adopt the existing deodorizing method described in the above-mentioned first piece of comparative literature, because deodorant just is impregnated in the filter material of dust bag and dust filter, the contact area of ​​filter material and dust is little again. , and the contact time is instantaneous, so there is a problem that a sufficient deodorizing effect cannot be produced

In this way, during the operation of the electric vacuum cleaner equipped with the above-mentioned conventional dust collection bag and dust collection filter, the exhaust air flow of the electric vacuum cleaner will contain different stench due to the type of dust and the accumulation period, which makes the user feel very uncomfortable. Comfortable

[0005] In addition, if the structure described in the above-mentioned second reference document is used to install a deodorant fragrance in the dust collection chamber, although the deodorizing components diffuse into the dust collection chamber, they can be absorbed into the dust collection bag in the electric vacuum cleaner. Deodorize the dust, so that the exhaust odor during work can be alleviated to a certain extent, but the function of the deodorizing fragrance is only to add other fragrances to the odor of the dust, although it can alleviate the exhaust odor to a certain extent, but The odor cannot be fundamentally eliminated, and the exhaust of the electric vacuum cleaner still contains unpleasant odors that vary depending on the type of dust inhaled

[0006] In addition, if the above-mentioned existing structure is adopted, in a bag-type vacuum cleaner that absorbs a large amount of dust and has a long storage period, since the dust suction airflow basically passes through the dust, when the dust suction capacity increases The amount of odor generation will also increase, and the amount of odor generation will increase significantly when it is close to the maximum allowable capacity of the dust bag

If only relying on the deodorizing effect of the deodorant fragrance, there will be a problem that almost no effect will be achieved
