Abstract

PURPOSE:To prevent the release of malodors by using a dust collecting bag formed by coating or impregnating a blank material, such as nonwoven fabric, with an acidic material having a carboxyl group or basic zinc carbonate material. CONSTITUTION:The dust collecting bag 1 is constituted of the nonwoven fabric consisting of fiber materials of pulp, natural fibers, synthetic fibers, etc., as a blank material and is formed by coating or impregnating this blank material with the acidic material having the carboxyl group and basic zinc carbonate material. For example, 1,2,3,4-butanetetracarboxylic acid is used as the acidic material having the carboxyl group at this time and 2ZnCO3.Zn(OH)2.H2O is used as the basic zinc carbonate material. The generation of malodorous elements from the refuse collected in the dust collecting bag is suppressed by a chemical reaction in the dust collecting bag 1 subjected to this treatment and, therefore, the release of the malodors during the operation of the cleaner is prevented and the execution of the cleaning without an uncomfortable use is possible. The generation of the malodors is similarly prevented when the dust collecting bag 1 is coated with the blank material subjected to a treatment or the blank material subjected to the treatment is disposed within the dust collecting bag 1 as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner capable of deodorizing exhaust gas.

[0002]

2. Description of the Related Art Conventionally, a bad odor generated from dust collected in a dust collecting portion of an electric vacuum cleaner may be discharged to the outside of the electric vacuum cleaner together with an exhaust flow of an electric blower. As a general means, a dust-collecting paper bag treated with a deodorant or a deodorizing filter provided at the exhaust port has been generally used.

[0003]

The offensive odor in the vacuum cleaner is caused by the organic substances collected as dust, such as food residue, hair, dandruff, and fleas and mites adhering to these substances, being oxidized or dusted inside the dust bag. It is generated because the substance decomposes into a malodorous substance by the decomposition action of microorganisms.

The above conventional deodorizing mechanism had some effect in removing these bad odors when the odor of the dust was low, but when the odor of the dust was strong, particularly, the odor of acidic substances generated from organic substances In regard to the above, there was almost no removal effect.

The present invention is intended to solve the above problems, and a first object of the present invention is to provide an electric vacuum cleaner capable of strongly preventing the discharge of offensive odors.

A second object of the present invention is to provide an electric vacuum cleaner having a more effective malodor removing effect.

[0007]

In order to achieve the above first object, the vacuum cleaner of the present invention is made of a non-woven fabric or the like made of a fiber material such as pulp, natural fiber or synthetic fiber, and at least the material is It has a dust bag coated or impregnated with an acidic substance having a carboxyl group or a basic zinc carbonate substance.

The vacuum cleaner according to the present invention has a dust bag covered with the treated material.

Further, in the electric vacuum cleaner of the present invention, the treated material is arranged inside a dust bag.

Furthermore, in order to achieve the above second object, the vacuum cleaner of the present invention has the treated material arranged in the exhaust port.

[0011]

With the constitution of the present invention, the malodorous substances such as ammonia and amines having basicity are changed into the substance having no malodorous substance by the chemical reaction with the acidic substance having the carboxyl group, and the acidic property is changed. The malodorous substances such as lower fatty acids represented by isovaleric acid are converted into substances having no malodorous substance by a chemical reaction with basic zinc carbonate, and both basic and acidic odors are removed.

The dust-collecting bag 1 used was a material manufactured by Miki Special Paper Co., Ltd. As the drug, 1,2,3,4-butanetetracarboxylic acid is used as an acidic substance having a carboxyl group, and 2ZnCO ₃ · Zn (OH) ₂ is used as a basic zinc carbonate substance.
- using the H ₂ O. In addition, here, the dust collection bag 1 that has been treated as both the inner paper and the outer paper is used.

FIG. 2 shows the outline of a test for collecting the exhaust of the vacuum cleaner and evaluating the performance of the dust bag of the vacuum cleaner. Reference numeral 21 is a vacuum cleaner, 22 is an exhaust collector, and 23 is an odor bag. is there. The vacuum cleaner 21 in FIG. 2 is a new one that has been sufficiently color-operated to remove the odor of resin and the like, and the vacuum cleaner 21 has no normal dust collecting bag (hereinafter referred to as a normal bag). ,
Further, a dust bag subjected to the above treatment (hereinafter referred to as a treatment bag) was attached, exhaust gas was sampled by the sampling device 22, and a sensory test was conducted by a 6-stage odor intensity method.

First, 20 g of vacuum cleaner dust was put in each of the normal bag and the processing bag, and the temperature was 25 ° C. and the humidity was 60%.
Store for 1 day in an air-conditioned room below. And vacuum cleaner 2
1, a dust bag is attached, and the exhaust gas is sampled in the odor bag 23 as shown in FIG. After that, sensory tests of the exhaust of the normal bag and the treated bag are performed. There will be 6 panels.

By repeating this operation, it is investigated how the odor intensity changes as the amount of dust increases to 20 g, 40 g, 60 g and 80 g.

The results are shown in FIG. The results are the average of the panels. From this result, it is found that the odor intensity of the exhaust gas of the initial processing bag is lower than that of the normal bag by 1 point or more, and the processing bag has a strong deodorizing effect against dust of the vacuum cleaner.

(Embodiment 2) Next, an embodiment of the second invention will be described with reference to FIG. In FIG. 4, 41 is a cleaner body, 42 is a dust collecting bag, and 43 is a processing material provided to cover the dust collecting bag 42, which treats paper so as to have a deodorizing function.
