Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner which emits a scent.

[0002]

2. Description of the Related Art Conventionally, an electric vacuum cleaner of this type has a structure as shown in FIG. 3, for example. That is, an electric blower 1 including a motor and a fan is housed in the rear body, and an exhaust port 2 is formed in the rear body. The front body has a dust collecting chamber 4 in which a paper bag 3 for filtering dust is stored.
A hose 5 is connected to the tip of the dust collection chamber 4, and an extension pipe and a floor nozzle (not shown) are attached. In general, a storage box 8 is provided on the upper part of the rear body, and the sintered alloy 6 impregnated with the liquid fragrance is arranged on the outside air and the communication port 7.

In the above structure, when the electric vacuum cleaner is operated, the air flow containing dust is sucked into the paper bag 3 in the dust collecting chamber 4 through the floor nozzle, the extension pipe (not shown) and the hose 5.
After being filtered, it is exhausted from the exhaust port 2 through the electric blower 1. At that time, a minute outside airflow including the fragrance flows into the electric blower 1 part from the sintered alloy 6 part impregnated with the liquid fragrance stored on the communication port 7 communicating with the outside air and exhausted from the exhaust port 2 together. By doing so, the scent was released.

[0004]

However, in the case of such a structure, a minute amount of outside air flows from 6 parts of the sintered alloy impregnated with the liquid perfume stored on the communication port 7 communicating with the outside air and burned. Since the vaporized fragrance is released by the external air flow passing through 6 parts of the bonded gold, the vaporized fragrance is very unstable in release, and there is a problem in that the amount of release is small.

The sintered alloy 6 stored in the storage box 8 and impregnated with the liquid perfume is always exposed to the outside air even when the vacuum cleaner is stopped. It had a problem that it vaporized and disappeared immediately.

Therefore, it is a first object of the present invention to provide a structure in which the vaporized fragrance is released very stably and the released amount is large. A second object is to ensure the release and stop of the vaporized fragrance, and to provide a leak-free structure.

[0007]

In order to achieve the above first object, the present invention accommodates a perfume box in which a perfume or a permeating material impregnated with a perfume is sealed inside a cleaner body having a built-in electric blower. However, two pipes are connected to the scent box, one of the pipes communicates with the outside of the cleaner body, and the other pipe communicates with the dust collection chamber.

In order to achieve the second object, the present invention has a structure in which a valve is attached to the end of a pipe communicating with the dust collecting chamber.

[0009]

In the above structure, when the electric vacuum cleaner is operated,
First, a negative pressure is generated in the dust collection chamber, and the air-fuel mixture containing the fragrance in the fragrance box is sucked through the pipe communicating with the dust collection chamber. The sucked air-fuel mixture passes through the electric blower unit and is diffused from the exhaust port to the outside air together with the exhaust flow. At the same time, since the inside of the fragrance box has a negative pressure, the outside air is sucked from the pipe side communicating with the outside of the cleaner body, and the sucked outside air is mixed with the vaporized liquid fragrance to generate a mixture. The generated air-fuel mixture is diffused again. As described above, the vaporized fragrance is diffused reliably and stably, and a large diffusion amount is maintained.

By installing a valve at the end of the pipe communicating with the dust collecting chamber, the vaporized fuel is released and stopped by opening and closing the pressure valve by operating and stopping the vacuum cleaner.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. 1 and 2, the same parts as those of the conventional example are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 9 in the figure is a fragrance box housed in the dust collection chamber 4, inside which the fragrance 1
It has a penetrant 11 impregnated with 0 and is sealed. Two pipes 12 and 13 are connected to the scent box 9 so as to communicate with the inside, the end of the pipe 12 communicates with the outside of the cleaner body, and the end of the pipe 13 collects dust. It communicates with the inside of the chamber 4. A pressure valve 14 is arranged at the end of the pipe 13 to open and close by the pressure difference in the dust collecting chamber 4 due to the operation and stop of the electric vacuum cleaner. That is, the inside of the dust collection chamber 4 becomes negative pressure due to the operation of the electric vacuum cleaner, and is opened, and the operation is closed when the operation of the electric vacuum cleaner is stopped.

The operation of the above structure will be described. When the main body of the vacuum cleaner is operated, an air flow containing dust is generated by the floor nozzle,
After being drawn into the paper bag 3 in the dust collection chamber 4 through an extension pipe (not shown) and the hose 5 and filtered, it passes through the electric blower 1 and
The gas is exhausted from the exhaust port 2. At that time, when the vacuum cleaner is operated, the inside of the dust collection chamber 4 first becomes a negative pressure, so that the pressure valve 1
4 is opened, and the air-fuel mixture containing the fragrance 10 in the fragrance box 9 is sucked into the dust collection chamber 4 through the pipe 13. The sucked air-fuel mixture passes through the electric blower 1 part and is diffused from the exhaust port 2 to the outside air together with the exhaust flow. At the same time, since the inside of the fragrance box 9 has a negative pressure, the outside air is sucked from the pipe 12 communicating with the outside of the cleaner body, and the sucked outside air is mixed with the vaporized liquid fragrance 10 to generate a mixture. The generated air-fuel mixture is diffused again. As described above, the fragrance 10 can be reliably and stably diffused, and a large diffusion amount can be maintained. Then, when the operation of the electric vacuum cleaner is stopped, the pressure valve 14 is closed so that the airflow into and out of the perfume box 9 is closed, and although the pipe 12 communicates with the outside air, there is no pressure difference, There is no movement and there is no diffusion of the air-fuel mixture of the fragrance 10. Almost no natural diffusion, and by disposing the pressure valve 14 at the end of the pipe 13, diffusion of the fragrance 10
The stop can be reliably performed.

In the above embodiment, the perfume box 9 has the penetrant 11 impregnated with the perfume 10 and is sealed, but the perfume 10 alone may be used. It is sufficient that the outside air is mixed with the vaporized fragrance 10 to generate a mixture.

[0014]

As is apparent from the above description of the embodiments, the electric vacuum cleaner of the present invention accommodates a perfume box in which a perfume or a penetrant impregnated with a perfume is sealed in the vacuum cleaner body, and the perfume box is provided. By connecting two pipes on the top, connecting one of the pipes to the outside of the vacuum cleaner body, and the other one to the dust collection chamber A negative pressure is created in the dust container storage chamber, and the air-fuel mixture containing the fragrance in the fragrance box is sucked into the dust collection chamber through the pipe. The sucked air-fuel mixture passes through the electric blower unit and is diffused from the exhaust port to the outside air together with the exhaust flow. At the same time, since the inside of the fragrance box has a negative pressure, the outside air is sucked from the side of the pipe communicating with the outside of the cleaner body, and the sucked outside air is mixed with the vaporized liquid fragrance to generate a mixture. The generated air-fuel mixture is diffused again. As described above, the fragrance has an effect that it can be reliably and stably diffused, and a large diffusion amount can be maintained.

By attaching a pressure valve to the end of the pipe communicating with the dust collection chamber, the pipe communicating with the inside of the dust collection chamber is opened and closed by opening and closing the pressure valve by operating and stopping the vacuum cleaner. It diffuses and stops the scent, and has the effect of reliably spreading and stopping the scent.
