Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a vacuum cleaner having an aromatic function.

(b) Prior art As a technology prior to the present invention, for example,
-111857, Japanese Patent Application Laid-open No. 143017/1983,
A vacuum cleaner is disclosed in which a fragrance is stored behind a filter in a dust collector. However, these conventional techniques have the disadvantage that a large amount of suction air hits the fragrance, and therefore the fragrance contained in the exhaust gas is too strong and the fragrance lacks persistence.

Furthermore, in Japanese Utility Model Application Publication No. 62-148243, an air freshener is provided outside the hole 10a communicating with the atmosphere side of the dust collection meter, but in this case, in the normal use state before the dust collection meter is activated, The fragrance of the air freshener does not come out at all, and once the dust collection meter is activated, all of the air that passes through the dust collection meter hits the air freshener. The drawback is that the fragrance contained therein is too strong and the fragrance is not long-lasting.

Furthermore, as a prior art, there is Japanese Patent Application Laid-Open No. 55-99231, but in this case, the aromatic agent is disposed at a position away from the passage path of the suction air, so the amount of the aromatic agent emitted is always constant, and the dust collection Even when there is a small amount of air freshener and the amount of air freshener emitted is small, there is no change in the amount of air emitted even when there is a large amount of collected dust and the odor from the dust is severe and a large amount of air freshener needs to be emitted. I couldn't resolve it.

(c) Problems to be Solved by the Invention The present invention provides a method for continuously imparting an appropriate amount of fragrance to the exhaust stream discharged from the main body of a vacuum cleaner over a long period of time, while also preventing the suction performance from deteriorating. The aim is to create a vacuum cleaner that is easy to use.

(d) Means for Solving the Problems The vacuum cleaner of the present invention includes a dust collection chamber that can be opened and closed by a dust collection lid, and a blower storage chamber that houses an electric blower that communicates the suction side with the dust collection chamber. a vacuum cleaner body having a vacuum cleaner body; a groove portion formed by a rib protruding from a low wall of a meter storage chamber formed on the upper part of the vacuum cleaner body;
a cover body that covers the upper surface of the groove portion, which integrally includes an aromatic agent storage portion at the upper end portion and a communication pipe facing the groove portion at the other end portion; an air passage formed by the cover body and the groove portion; A dust collection meter connected to an opening formed at one end of the air passage, a communication hole communicating with the suction side of an electric blower provided at the bottom of the other end of the air passage, and a part that can be detachably attached to the air freshener storage section. It is characterized by being similar to the stored air freshener.

(e) Effect With the above configuration, the cover covering the groove provided in the meter storage chamber forms an air passage and a communication pipe, and also forms an air freshener storage section.

Further, while the amount of dust collected is small, air does not flow to the dust collection meter, and only a small amount of the amount of air emitted from the fragrance is emitted into the suction space due to natural diffusion. When the amount of dust collected further increases and air flows into the dust collection meter, the air in the communication pipe flows due to the air flow, and the amount of aromatic agent diffused increases.

The air passes through and is sucked into the electric blower 9, and is then exhausted to the outside of the cleaner body 1 from the exhaust port 7 of the blower storage chamber 8. At this time, the aroma emitted from the aromatic metal 35 gradually spreads into the suction space 28 via the communication pipe 32 and the air passage 27, and an appropriate amount is mixed with the suction air and exhausted outside the vacuum cleaner main body 1. A suitable amount of fragrance can be continuously applied to the stream over a long period of time. Furthermore, since the flow path of the suction air is not obstructed by the aromatic metal 35, the suction performance of the suction air does not deteriorate.

Furthermore, adjustment of the amount of fragrance from the aromatic metal 35 can be performed by replacing the adjustment plate 37 with any preliminary adjustment plate 40, 4.
This can be done arbitrarily by replacing it with 1.

In addition, when the aromatic agent is completely diffused from the aromatic metal 35, the aromatic agent is transferred to the aromatic metal 35 from the refilling aromatic agent storage bin 44 stored in the aromatic agent storage chamber 30.
It is only necessary to impregnate the exhaust gas with the fragrance, and the exhaust stream can be scented again with a simple operation.

If it is desired to obtain a different aroma, the preliminary aroma metal 39 is impregnated with an aromatic agent having a different aroma and used in place of the aroma metal 35.

Since the preliminary adjustment plates 40, 41, the preliminary aroma metal 39, and the replenishment aroma agent storage bottle 44 are stored in the aroma agent storage chamber 30, they will not be lost.

(G) Effects of the Invention Since the vacuum cleaner of the present invention is configured as described above, the fragrance emitted from the air freshener is mixed with the suction air in an appropriate amount according to the required amount and is exhausted outside the vacuum cleaner body. , it is possible to continuously impart an appropriate amount of aroma to the exhaust stream over a long period of time. Furthermore, since the air passage is formed by the cover and the groove, and the communication tube is also integrally formed, the fragrance storage section can be constructed with a simple structure and a small number of parts.
