Exhaust wind filtration device of vacuum cleaner

The present invention relates to a vacuum cleaner which sucks external air at a moment by suction power of a motor and also sucks dust and foreign substances from the cleaning part together with suction air, and in particular, vacuum is installed by mounting a filtering means on an exhaust grill of the vacuum cleaner. The present invention relates to an exhaust wind filtration device for a vacuum cleaner that can reduce filtration and exhaust noise of foreign substances contained in the exhaust wind discharged to the outside of the main body during cleaning.

In general, a vacuum cleaner forcibly sucks dust and other contaminants together with air from the outside by suction power using an internal pressure and an external pressure difference generated as a motor equipped with an impeller on a rotating shaft rotates at a high speed. To clean the contaminated area.

As shown in FIG. 1, the main components of the vacuum cleaner include a suction device 100 which sucks dust or foreign matter by the suction force of air, and a dust collecting location of the dust sucked by the suction device 100. The communication device 200 to be smoothly transferred to the furnace, and the main body 300 is to collect the dust moved by the communication device 200.

Here, the suction device 100 is composed of two transfer wheels 110 installed on both sides and the connecting pipe 120 is formed integrally with the rear upper end of the upper cover to be connected to the communication means 200. have.

Therefore, when the operator applies power to the main body 300 using the power plug 350 of the cord reel device 420 and turns on the power switch, the motor 430 installed in the main body 300 is provided. ) Is rotated at a high speed, a strong suction force is generated.

In addition, when the user operates the power switch of the handle adjusting unit 230, the rotary brush installed in the suction device 100 is rotated at a high speed.

At this time, the outside air is sucked into the suction device 100 by the suction force of the motor 420, the external air introduced into the suction device 100 through the communication device 200 inside the body 300 Of course, the air introduced into the main body 300 is discharged to the outside of the main body 300 through the exhaust grill 460 through the chamber in which the dust collecting chamber 370 and the motor 430 are installed. do.

On the other hand, the dust and foreign matters of the cleaning part is sucked into the suction device 100 together with the external air and introduced into the main body 300 through the communication device 200, as well as the dust and foreign matter introduced into the main body 300. The back is collected by a dust bag 410 installed in the dust collecting chamber 370.

At this time, the odor generated in the dust collecting chamber 360 when collecting dust and foreign matter to the dust bag 410 is removed by the first filter 440 installed in the partition panel 360, as well as the motor when driving the cleaner The smell of carbon powder generated at 430 is removed by the second filter 450.

However, according to the conventional vacuum cleaner, the carbon powder and its odor generated in the motor 430 at the time of cleaning are not completely removed by the second filter 450, and the main body is exhausted by the exhaust force of the motor 430. There is a problem that is discharged to the outside of the 300 to harm the human body.

Accordingly, the present invention has been made to solve the above problems, by purifying the foreign matters such as carbon powder contained in the exhaust wind discharged at the rear of the exhaust grill, even through the filter means to absorb the exhaust noise, cleaner The purpose of the present invention is to provide an exhaust wind filtration device for a vacuum cleaner, which can promote the commercialization of the product.

Hereinafter will be described the action of the filtering means of the present invention configured as described above.

When cleaning the contaminated area using a vacuum cleaner equipped with a filtration means to the front of the exhaust grill 460 as described above, first, the dust of the contaminated area or other foreign matter is strongly Due to the suction force, the dust is collected by the dust bag installed in the dust collecting chamber via the suction device and the communication device.

At this time, the dust bag is to collect only the dust in the outside air, including the dust inside, and the clean air is discharged to the exhaust grill 460, in this way, the exhaust wind discharged through the dust bag includes the odor in the dust chamber. In addition, some of the carbon powder generated from the driving motor may be included.

Therefore, the exhaust wind discharged through the exhaust port 462 of the exhaust grill 460 flows into the air collecting container 500 through the inlet 502, and the exhaust wind introduced into the air collecting container 500 is again. It passes through the diaphragm member 506 and enters the opening 612 of the first connection member 610 through the exhaust port 504.

Thereafter, the exhaust wind introduced into the first connection member 610 passes through the puncturing part 614 through the check valve 616, and the flow rate and pressure of the exhaust wind are partially alleviated. The inlet 512 flows into the inlet 512, whereby the pressure of the exhaust wind is alleviated again by the sponge 513 in the inlet 512, and then into the reservoir 518 in the first filter cylinder 510 through the communication port 515. Inflow.

At this time, the exhaust wind flowing into the reservoir 518 of the first filter cylinder 510 is included in the exhaust wind while sequentially passing through the partition member 516 having through holes 517 formed in different sizes in the stored water. Used carbon powder or odor is filtered by water and purified.

And the through hole 517 formed in the partition member 516 has a larger shape toward the exhaust port 514, can be alleviated when the exhaust wind is passed by the water stored in the reservoir 518 receives the back pressure. The water stored in the reservoir 518 of the first filter barrel 510 is prevented from overflowing with the pressure of the exhaust wind.

In addition, the blocking plate member 519 provided below the exhaust port 514 has a plurality of perforation holes 519a so that the exhaust wind passes through the last partition member 516 in the first filter cylinder 510. Although the water of the water tank 518 is splashed when discharged to the exhaust port 514 via the 517, the blocking plate member 519 collects the splashing water droplets by the surface tension in the plurality of holes 519a. The exhaust port 514 is prevented from being discharged to the outside.

That is, when water droplets form in the punching hole 519a of the blocking plate member 519 with surface tension, the water droplets that spring up later collide with the water droplets formed in the punching hole 519a and fall into the reservoir 518 below. Done.

Meanwhile, the exhaust wind primarily purified while passing through the first filter cylinder 510 as described above is introduced into the second filter cylinder 520 through the second connection member 620 and has a wave shaped exhaust wind flow passage ( After passing through 526, the pressure is once again reduced, and then the exhaust wind passes through the reservoir tank 528 in which a predetermined amount of water is stored in sequence, thereby purifying the carbon powder or odor contained therein. Repeatedly, you get additional purification.

In addition, the exhaust wind purified by sequentially passing through the first filter cylinder 510 and the second filter cylinder 520 is finally discharged to the outside through the exhaust port 524 of the second filter cylinder 520.

In this way, when the carbon powder or odor contained in the exhaust wind discharged to the outside of the main body through the exhaust grill 460 during vacuum cleaning is completely purified by the filtering means, it is possible to reduce environmental pollution as well as damage to the user's body. In addition, the exhaust noise caused by the exhaust wind is also reduced.

As described above, according to the present invention, it is possible to purify carbon dust or odor contained in the exhaust wind discharged to the outside after cleaning using the water stored therein, and thus to remove harmful elements of the human body. Noise can also be reduced, thereby improving the merchandise.
