Description

[Detailed description of the invention] <Industrial application field> The present invention has an electric blower installed inside the vacuum cleaner body, and the operation of the electric blower causes air to be sucked in through the air intake port provided in the vacuum cleaner body. A dust collection bag having a suction opening for collecting dust is provided, the dust collection bag is stored in a dust collection chamber provided in the vacuum cleaner body, and the dust collected in the dust collection bag is deodorized and sterilized. The present invention relates to a vacuum cleaner equipped with an ozone generator that generates ozone.

<Prior Art> Conventional vacuum cleaners have an electric blower built into the main body of the vacuum cleaner, and when the electric blower operates, a suction system collects dust sucked in through an intake port provided in the main body of the vacuum cleaner. A dust collection bag having an opening is provided, the dust collection bag is stored in a dust collection chamber provided in the vacuum cleaner body, and ozone is generated to deodorize and sterilize the dust collected in the dust collection bag. A generator is provided, and the ozone generated by the ozone generator is sucked in by the operation of the electric blower, and at the same time, ozone is supplied into the dust bag from the suction opening of the dust bag, and the ozone is collected. There was a device that deodorized and sterilized the dust collected in dust bags.

Further, when the electric blower is stopped, ozone is generated by the ozone generator, and the ozone is naturally diffused from the suction opening of the dust bag into the dust bag or inside the dust collection chamber (to the outside of the dust bag). There was one that deodorized and sterilized the inside of the dust collection bag or the inside of the dust collection chamber.

<Problem to be solved by the invention> In the former type of vacuum cleaner described above, the ozone generated by the ozone generator reaches inside the dust collected in the dust bag and deodorizes and sterilizes it, but there is a problem in that the concentration of ozone decreases because outside air is drawn in by the electric blower, making it impossible to perform sufficient deodorization and sterilization.

In the case of the latter, ozone is deodorized and sterilized by the natural diffusion of ozone, so the ozone concentration does not decrease. The problem was that it was not possible to do so.

An object of the present invention is to provide a vacuum cleaner that eliminates the above-mentioned problems.

<Means for solving the problem> In order to solve the above-mentioned problems, the vacuum cleaner of the present invention has an electric blower built into the main body of the vacuum cleaner.
A dust collection bag having a suction opening for collecting dust sucked in through an intake port provided in the vacuum cleaner body by the operation of the electric blower is provided, and the dust collection bag is provided in the vacuum cleaner body. An ozone generator is installed in the dust collection chamber, which generates ozone to deodorize and sterilize the dust collected in the dust collection bag, and the ozone generated by the ozone generator is passed through the suction opening of the dust collection bag. A first ozone supply path is provided to supply the ozone into the dust collection bag, and a second ozone supply path is provided to supply the ozone into the dust collection chamber, and the second ozone supply path is provided when the electric blower is operated. A valve is installed to close the

<Function> In the vacuum cleaner described above, when the electric blower is operated, the valve closes the second ozone supply path, so that the ozone generated by the ozone generator is collected through the first ozone supply path. The dust enters the dust collecting bag through the suction opening of the bag, and the dust is deodorized and sterilized. When the electric blower is stopped, the valve is opened, and the ozone generated by the ozone generator is transferred to the first and second dust collection bags. The ozone is naturally diffused into the dust collection bag and the dust collection chamber (outside the dust collection bag) from the ozone supply path, and deodorizes and sterilizes the dust inside the dust collection bag and the entire inside of the dust collection chamber.

<Example> An example of the vacuum cleaner of the present invention will be described with reference to the drawings.

The vacuum cleaner of the present invention has an electric blower 2 installed inside a vacuum cleaner body 1.

An exhaust port 9 is provided on the exhaust side of the electric blower 2.

The dust collection bag 4 has a mounting part 11 having a suction opening 10 for sucking dust, and the mounting part 11 is attached to a dust collection bag holder 12 provided inside the lid 5 of the dust collection chamber 3. A dust collection bag 4 is stored in the dust collection chamber 3. The lid 5 has a suction opening 10 for the dust collection bag 4.
A gasket 13 is provided which communicates the dust collection chamber opening 6 of the lid 5 with the dust collection chamber opening 6 of the lid 5.

The ozone generator 7 is provided with a case body 14 on the lid 5 of the dust collection chamber 3, and the case body 14 has a first opening 15 for supplying ozone into the dust collection bag 4 on the lid 5 of the dust collection chamber 3. A supply wall section that is provided near the dust collection chamber opening 6 of No. 5 through the lid 5, and supplies ozone from the first opening into the dust collection bag 4 from the suction opening 10 of the dust collection bag 4. 16 to the above package 1
3, the first opening 1 of the case body 14
5. A first ozone supply path 17 is formed by the supply wall portion 16 of the packing 13 and the suction opening 10 of the dust collection bag 4. Further, a second opening 18 is provided in the case body 14 and serves as a second ozone supply path for penetrating the lid 5 and supplying ozone into the dust collection chamber 3.
and the second opening 1 is provided in the case body 14.
Valve gasket 20 can open and close valve 19 that closes valve 8.
It is provided through. The valve 19 is always urged in the open direction by a spring 21. The case body 14 is provided with an inlet 22 for letting the air in the vacuum cleaner body 1 flow in when the electric blower 2 is operated, and the case body 13 is provided with an ozone generating electrode 23 and a lead is connected to the ozone generating electrode 23. A high pressure generator (not shown) is connected via line 24.

The operation of the vacuum cleaner configured as above will be explained.

First, when the power plug (not shown) of the vacuum cleaner is inserted into a power outlet, power is supplied to the high voltage generator, which generates high voltage.The high voltage is applied to the ozone generating electrode 23 via the lead wire 24, and the Ozone is generated by discharging the ozone generating electrode 23. At this time, since the valve 19 opens the second opening 18 by the bias of the spring 21, the ozone is supplied from the second opening 18 and the first ozone supply path 17 to the dust collection chamber 3.
and into the dust collection bag 4. Since the electric blower 2 is stopped and outside air is not being sucked in, highly concentrated ozone is supplied to deodorize and sterilize the entire inside of the dust collection chamber 3 and the dust inside the dust collection bag 4. The power supply to the high voltage generator may be continued for a certain period of time or until cleaning is started.

Next, when the electric blower 2 is operated to start cleaning, the electric blower 2 is operated and the high pressure generated by the high pressure generator is transferred to the ozone generating electrode 2.
3 to generate ozone, the operation of the electric blower 2 causes the air inlet 8 of the vacuum cleaner body 1 to
Dust is sucked into the dust collection bag 4 through the dust collection chamber opening 6 of the lid 5 and the suction opening 10 of the attachment part 11 of the dust collection bag 4. At this time, the case body 1 of the ozone generator 7
Air is also sucked into the dust collection chamber 3 from the inlet 22 of No. 4 through the second opening 18, and this air pressure causes the valve 19 to close against the bias of the spring 21 and open the second opening 1.
8 is closed, and ozone generated by the ozone generating electrode 23 is supplied from the first ozone supply path 17 into the dust collecting bag 4 together with dust. On this occasion,
Although the concentration of ozone decreases due to the intake of outside air, the ozone penetrates into the inside of the dust due to the action of the electric blower 2, and deodorizes and sterilizes the dust.

In order to generate ozone when the electric blower 2 is stopped, an ozone generation switch is provided on the vacuum cleaner body 1, and by turning on the ozone generation switch, ozone is generated for a certain period of time when desired by the user. Good too.

<Effects of the invention> The present invention can supply ozone both when the electric blower is stopped and when it is in operation, but when the electric blower is stopped, high concentration ozone is not drawn in because outside air is not being sucked in. By being supplied into the dust collection bag and the dust collection chamber and naturally diffusing, the inside of the dust collection bag and the dust collection room are deodorized and sterilized.

Furthermore, while the electric blower is in operation, ozone is sucked into the dust collection bag together with the outside air, so that the ozone penetrates into the dust and effectively deodorizes and sterilizes it.
