DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner for performing exhaust deodorization.

[0002]

2. Description of the Related Art Conventionally, a bad smell generated from dust collected in a dust collecting portion of a vacuum cleaner may be discharged to the outside of the vacuum cleaner together with an exhaust flow of an electric blower. As a means, a dust collecting paper bag treated with a deodorizing agent, a deodorizing mechanism such as covering the dust collecting chamber with a deodorizing agent, or a deodorizing filter at an exhaust port is generally used.

[0003]

The bad smell in vacuum cleaners is caused by organic substances collected as garbage, such as food debris, hair, dandruff, and fleas and mites adhering to these substances being oxidized or trapped inside the dust bag. It is generated because it is converted into a substance that emits offensive odor by the decomposition action of microorganisms.

[0004] The conventional deodorizing mechanism described above has some effect in removing the offensive odor when the amount of dust is small. However, when the use of the vacuum cleaner is long, such as one month, the amount of dust increases. However, the odor of the garbage became strong and the effect could not be expected.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a vacuum cleaner capable of maximizing the effect of a deodorant and preventing emission of a bad odor for a long time.

[0006]

To achieve the above object, a vacuum cleaner according to the present invention is provided with a deodorizing body and a fan in a dust collecting chamber, and the fan is operated for a predetermined time before the electric blower is driven. By driving, the odor due to the dust in the dust collection chamber is repeatedly removed by passing through a deodorizing body.

Further, in the vacuum cleaner of the present invention, the fan is periodically operated to remove a bad smell.

[0008]

According to the constitution of the present invention, each time the cleaner is used, the odorous components inside the dust collecting chamber are stirred and passed through the deodorizing body repeatedly, thereby increasing the effectiveness of the deodorizing body. Without this, it is possible to improve the performance of exhaust gas deodorization and maintain the effect for a long time.

[0009] Further, by operating the fan regularly, the odor can be removed in advance when the vacuum cleaner is used, so that the vacuum cleaner can be used without any difference from the use of a normal vacuum cleaner.

(Embodiment 1) An embodiment of the present invention will be described below with reference to FIG. A dust collecting chamber 2 inside the cleaner body 1;
An electric blower 3 is provided. Further, a dust-collecting paper bag 4 and a fan 5 are arranged in the dust-collecting chamber 2, and when the fan 5 is driven, an air flow is generated in the direction of the arrow, and the air in the dust-collecting chamber 2 is removed. 4 is repeatedly passed.

In a vacuum cleaner of a type in which sucked dust is collected by a paper bag, the dust collecting paper bag 4 is detachably attached to the dust collecting chamber 2 as shown in FIG. As the paper bag 4, a dust bag carrying or mixing activated carbon (hereinafter referred to as a deodorant) was used.

As the deodorant, one prepared using activated carbon fiber paper manufactured by Kuraray Chemical Co., Ltd. was used. This activated carbon paper has a basis weight of 50 g / m ² and an activated carbon content of 50 g / m ² .
%, And about 0.36 m ^{2 was} used for the bag.

[0013] Vacuum cleaner odors include dust odors, pet and food odors, moldy odors and other living odors. These components include a variety of components such as lower fatty acids, acetaldehyde, and ammonia. It is.

Activated carbon fiber paper has an effect on all kinds of odors in daily life, and can cope with any of the above-mentioned garbage odors.

FIG. 2 shows a control circuit for operating the fan 5 provided in the dust collection chamber 2 for a certain period of time before driving the vacuum cleaner and sucking dust.

The control means 6 in the control circuit shown in FIG. 2 can be easily realized by using a microcomputer or the like. When the switch 7 of the vacuum cleaner is turned on, the control means 6 operates before the electric blower 3 is operated. The fan 5 provided in the dust collection chamber 2 is controlled so that it can be operated for a predetermined time. The measuring means 8 can operate the fan 5 provided in the dust collecting chamber 2 for a certain period of time by using a timer or the like, and the switch 7 is attached to the outside of the cleaner body 1. It is assumed that the user can operate the fan 5 in the dust collection chamber 2 as needed. In the figure, reference numeral 9 denotes a power supply circuit.

With this control circuit, when the switch 7 is turned on, the fan 5 provided in the dust collecting chamber 2 is operated for about 3 minutes before the operation of the cleaner main body 1, and thereafter, the dust suction of the cleaner main body 1 is performed. Is what begins.

The direction of air flow from the fan 5 is the direction of suction from the dust-collecting paper bag 4, and the air path of the fan 5 is the direction of the arrow in FIG.

At this time, when the fan 5 is operated, the odor inside the dust-collecting paper bag 4 is sucked out by the fan 5 and passes through the dust-collecting paper bag 4, that is, the deodorizing body. It will pass through the deodorant. Therefore, during the operation of the fan 5, the malodorous components inside the dust collection chamber are agitated and pass through the deodorizing body many times.

FIG. 3 is a schematic diagram of a test for collecting exhaust gas from a vacuum cleaner and evaluating the deodorizing performance.
1 is an odor bag.

The cleaner body 1 shown in FIG. 3 is an unused product which has been sufficiently operated to remove odors such as resin and the like. The cleaner body 1 has a deodorizing body, a fan 5, a control circuit, and a sampling device. The exhaust gas was sampled according to No. 10, and a sensory test was conducted by a six-stage odor intensity method.

First, 40 g of vacuum cleaner dust is put in the dust-collecting paper bag 4 as a deodorizing body, and the temperature is assumed to be 30 in summer.
Stored in a room air-conditioned at 80 ° C. and 80% humidity. After operating the fan 5 for 3 minutes by the control circuit shown in FIG.
The vacuum cleaner was operated for 15 minutes to collect 40 grams of dust. Before the dust was sucked, the exhaust gas was sampled and subjected to a sensory test. This operation was repeated once a day for 7 days in the air-conditioned room to examine how the odor intensity changes. As a blank experiment, fan 5
And measure the odor intensity without the control circuit,
The effects were compared.

FIG. 4 shows the results. In addition, a result displays the average of a panel. Although there is a disparity, the amount of garbage from a general household vacuum cleaner is about 100 g per month, and here, the standard of the amount of garbage for two months is 200 g. According to the results, the odor intensity of the exhaust gas with the fan 5 and the control circuit attached was lower than that of the blank experiment. In particular, even if the amount of dust becomes 200 g or more after the fifth day, the effect is improved. It can be seen that the exhaust gas deodorizing effect can be maintained even if it is stored in the dust collection chamber 2 for more than a month.

(Embodiment 2) A second embodiment of the present invention will be described with reference to FIG.

In FIG. 5, the same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. In the dust collection chamber 2, a filter member 12 that covers the dust collection paper bag 4 and has a deodorizing function is disposed.

The filter member 12 has a deodorant 13 therein.

MS-6 is an impregnated charcoal of aniline phosphate and aniline, and MS-7 is an impregnated charcoal of aniline. This deodorant is made of a 7 mm thick solid knitted fabric RH made by Asahi Kasei.
The filter member 12, that is, a deodorizing body is prepared by uniformly bonding a total of 170 g to 37-1 and bonding a polyester mesh made by Mitsubishi Rayon using an adhesive interlining made by Kurashiki Spinning. The deodorizing body is formed so as to be arranged in the cleaner body 1 so as to cover the dust collecting paper bag 4. The created filter member 12 is arranged so as to cover the outside of the dust collection paper bag 4.

Regarding the effect of the deodorant 13, MS-4 is particularly effective on hydrocarbons, MS-5 is ammonia, MS-6 is acetaldehyde, and MS-7 is particularly effective on hydrogen sulfide. When used in a formulation, it has an extremely effective effect on all kinds of offensive odors, and can cope with any odor.

Other conditions, such as a fan control circuit and an air passage for the fan 5, are the same as in the first embodiment.

At this time, when the fan 5 is operated, as in the first embodiment, the odor inside the dust-collecting paper bag 4 is sucked out by the fan 5 and passes through the filter member 12 to go around the inside of the dust-collecting chamber 2. After that, it passes through the filter member 12 again. Therefore, during the operation of the fan 5, the offensive odor component in the dust collection chamber 2 is stirred and repeatedly passed through the filter member 12.

As in the case of Example 1, evaluation is performed by a sensory test according to the method shown in FIG. Further, similarly to the first embodiment,
As a blank experiment, the odor intensity was measured without the filter member 12 and the fan 5 attached, and the effects were compared.

FIG. 6 shows the results. According to the results, in this case also, the odor intensity of the exhaust gas with the fan 5 and the control circuit attached was lower than that of the blank experiment, and the exhaust deodorizing effect was maintained even if the collected dust was stored in the dust collection chamber 2 for more than two months. It turns out that it has the effect that can be done.

In comparison with FIG. 4, it can be seen that this case has a very strong effect.

(Embodiment 3) A third embodiment of the present invention will be described. The third embodiment is the same as the first embodiment, except for the control circuit.

FIG. 7 shows a control circuit which can automatically operate the fan 5 of the dust collecting chamber 2 periodically even when the vacuum cleaner is not operated, that is, even when the power cord of the vacuum cleaner is not connected to the outlet.

In the control circuit of FIG. 7, the control means 6, the switch 7, and the measuring means 8 are the same as those in FIG. 2, and the rechargeable battery 14 can be used even if the vacuum cleaner is not connected to the outlet.
It is assumed that the rechargeable battery 14 can be operated for a predetermined time by the voltage from the rechargeable battery 14 and that the rechargeable battery 14 is charged while the vacuum cleaner is connected to the outlet by the charging circuit 15.

The control circuit automatically operates the fan 5 for about three minutes per day. A sensory test was conducted in the same manner as in Example 1 to examine how the odor intensity changes.

FIG. 8 shows the results. Again, fan 5
Further, the odor intensity of the exhaust gas to which the control circuit was attached was lower than that of the blank experiment, and it was found that the exhaust gas had an effect of maintaining the exhaust deodorizing effect.

(Embodiment 4) A fourth embodiment of the present invention will be described. The fourth embodiment is the same as the second embodiment, except for the control circuit. Further, it is assumed that the control circuit is the same as that of the third embodiment.

Similarly, a sensory test was conducted to examine how the odor intensity changes. The results are shown in FIG. Here, too, it can be seen that the odor intensity of the exhaust gas to which the fan 5 and the control circuit are attached is lower than that of the blank experiment, and that the exhaust gas deodorizing effect can be maintained.

[0040]

According to the structure of the present invention as described above, the fan is operated for a certain period of time before the electric blower is driven, whereby the odorous components in the dust collecting chamber are agitated and arranged in the dust collecting chamber. The exhausted deodorant passes through the deodorant many times, so that the performance of the exhaust deodorizer can be improved and the effect can be maintained for a long time without increasing the effectiveness of the deodorant. It can be prevented from being released and can be cleaned without discomfort.

Also, by operating the fan regularly, the odor can be removed in advance when the vacuum cleaner is used, so that it can be used as in a normal vacuum cleaner.
It is easy to use.
