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, and more particularly, to an electric vacuum cleaner having a function of deodorizing a bad smell discharged from the electric vacuum cleaner and a storage case having the function of deodorizing. It concerns vacuum cleaners.

[0002]

2. Description of the Related Art In an electric vacuum cleaner, a bad odor generated from dust collected in a dust collecting bag is discharged from an exhaust port every time cleaning is performed, and the person who fills the room and cleans the surroundings. Was a source of discomfort to.

In order to eliminate such a bad odor, there is a filter at the exhaust port containing activated carbon. However, since the deodorizing effect of activated carbon does not last for a long time, it is necessary to replace the filter frequently. Not only is it troublesome, but there is a problem that the financial burden on the user increases. Also,
It is possible to put granular activated carbon in the dust bag,
In this method, activated carbon prepared separately has to be put in a dust bag, which is troublesome, and the amount of the activated carbon is not constant, which may be wasteful, or a small amount may not provide a sufficient deodorizing effect. There are various problems.

Therefore, for example, Japanese Patent Laid-Open No. 61-62431.
As shown in Japanese Patent Laid-Open No. 63-160628, an electric vacuum cleaner in which activated carbon fibers are woven into a dust collecting bag to absorb a bad odor, or as shown in Japanese Patent Laid-Open No. 63-160628, There has been proposed an electric vacuum cleaner in which a fragrance bag whose entire circumference is sealed is arranged at a part or one side of a collecting filter, and the fragrance is gradually exhibited from the fragrance bag and exhausted from an exhaust port.

In addition, for example, the actual utility model Sho 60-188557.
As shown in Japanese Unexamined Patent Application Publication No. JP-A-61-64857, an electric vacuum cleaner in which a mouthpiece of a paper bag filter is impregnated with an aromatic agent, and as shown in Japanese Utility Model Laid-Open No. 61-64857, a deodorant and / or an aromatic agent is discharged through an air discharge passage An electric vacuum cleaner installed at the outlet has been proposed.

[0006]

Among the electric vacuum cleaners provided with the above-mentioned means for removing odors, those using activated carbon have a short effective period and therefore the dust collecting bag must be frequently replaced. For this reason, not only is it troublesome, but there is a problem that it causes an increase in cost. Moreover, since deodorization by activated carbon is physically performed, it is desirable to use a large amount in order to improve the deodorization effect. In the case of the machine, the deodorizing effect was not sufficient because the capacity was limited.

When a fragrance (fragrance) is used,
It is difficult to select because some people like and dislike the scent, and in this case, since there is no deodorizing effect, the malodor continues to increase, so a mixed odor of perfume and malodor is emitted along with the exhaust, and depending on the perfume used It may be more uncomfortable than before.

Therefore, even if the shutter 26 is opened or the lid 27 is removed during use, no odor is emitted.

Example 10. The tenth embodiment of the present invention is
As shown in FIG. 4, the connection part 29 of the hose 28 is connected to the suction port 4 of the cleaner body 1, and the hand pipe 30 is inserted into the exhaust port 5 to form a loop-shaped air passage. Then, a volatile deodorant (for example, deodorant SD-NAN sold by Shoko Chemical Laboratory Co., Ltd.) is adhered or impregnated in this air passage (for example, the partition wall 8), or is kneaded. It is the one in which the embedded member 31 is attached.

In the present embodiment configured as described above,
The connection part 29 of the hose 28 is connected to the suction port 4 of the cleaner body 1, and the hand pipe 30 is connected to the exhaust port 5 to drive the electric blower 10. As a result, an air flow in the direction of the arrow is generated and circulates in the looped air passage. As a result, the member 31
Of the deodorant volatilizes and circulates in the air passage together with the air flow, and removes the bad odors in the hose 28 and the cleaner body 1 to make them odorless. In this case, if the circulation time of the air flow is lengthened, the temperature in the air duct rises, so that the heat activates the volatile deodorant, which can enhance the deodorant effect.

Example 11. FIG. 5 is a vertical sectional view of an eleventh embodiment of the present invention. The same parts as those in the embodiment of FIG. 1 are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 32 denotes an adapter formed by molding synthetic resin, for example, which is provided on one wall of the main body 33 and a hollow main body 33 having a cylindrical shape, a box shape, or the like.

The air sucked from 5 passes through the impregnating material 36, and is discharged from the dust bag 13 through the blower chamber 7 and the exhaust port 5. At this time, the gasified deodorant passes through the dust collecting bag 13 and the inside of the cleaner body 1 together with the air flow, and removes the bad odor in the air passage.

If the adapter 32 is connected to the suction port 4 even during storage after cleaning, the deodorant in the adapter 32 volatilizes and flows into the dust collecting bag 13 to generate a bad odor. When the bad odor in the dust bag 13 flows out from the opening 35 through the impregnating material 36, the air deodorized and deodorized by the deodorant flows out. When the deodorant volatilizes and the deodorizing effect decreases, only the impregnating material 36 needs to be replaced.

Example 12. FIG. 6 shows another embodiment of the adapter 32.
