Main body of vacuum cleaner

The present invention relates to a vacuum cleaner which sucks external air by suction force of a motor and sucks dust and foreign substances in the cleaning part together with suction air, in particular, of exhaust pollutants discharged to the outside of the main body during vacuum cleaning. The present invention relates to a main body of a vacuum cleaner, in which emissions are reduced, as well as exhaust noise is reduced.

In general, the main components of the vacuum cleaner as shown in Figure 1, the suction device 100 to suck the dust or foreign matter by the suction force of the air, and the dust collected by the suction device 100 to collect It is composed of a communication device 200 to be smoothly transported to the place, and the main body 300 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.

In addition, the communication device 200, the first extension pipe 210 and the second extension pipe 220 of the plastic material coupled to communicate with the hollow portion of the connecting pipe 120 and the extension pipe 210, 220 Combined with the handle of the power switch (On) / off (OFF) of the power supply and the wind speed control switch 230 for controlling the strength and weakness of the wind speed, and the handle adjustment unit 230 The hose 240 is coupled to communicate with, of course, naturally made, and the connection pipe 250 is integrally coupled with the hose 240 is connected to the main body 300.

In addition, the main body 300 includes a connection port 310 to which the end of the connection pipe 250 is connected, a dust indicator 320 to display the amount of dust collected, and two transport units installed at both sides. The wheel 330, the carrying handle 340 to be easily carried by the operator for the movement of the work place, and a power plug 350 to supply power.

Meanwhile, as shown in FIG. 2, inside the main body 300, the dust collecting chamber 370 formed in front of the partition panel 360 is sucked by the suction device 100 to communicate with the communication device 200. The dust bag 410 is detachably installed to collect the dust and foreign substances of the cleaning part moved into the interior of the main body 300 through the chamber (not shown) formed around the partition panel 360. And a cord reel device 420 for applying external power to the main body 300 and a motor 430 driven by the applied power to generate suction power.

In addition, as shown in FIG. 2, the partition panel 360 of the main body 300 is provided with a first filter 440 to remove odors of dust and foreign matter collected in the dust bag 410. Of course, a second filter 450 is installed at the rear portion of the motor 430 to remove the odor of carbon (carbon) powder generated by the driving of the motor 420.

In addition, the rear portion of the main body 300, as shown in Figure 2, the exhaust grill 460 of a predetermined size so as to surround the rear of the cord reel device 420 and the motor 430 is detachably installed have.

The first exhaust wind guide member 547 and the second exhaust wind guide member 549 are water 900 contained in the exhaust wind flow passage 545, as shown in FIGS. 4, 5, and 8. The second through-hole 541 is formed in a wave shape to prevent backflow into the interior of the connecting pipe 530 as well as to reduce the exhaust noise during the discharge of the exhaust wind.

Hereinafter, the operation of the filter means of the present invention will be described in detail.

First, as shown in FIG. 2, the operator applies power to the main body 300 by using the power plug 350 of the cord reel device 420 and the dust of the cleaning part using the suction device 100. And clean the foreign objects.

That is, when the dust and foreign matters of the cleaning part are sucked into the suction device 100 by the strong suction force of the motor 430 shown in FIG. 2 together with the external air, the dust is introduced into the main body 300 through the communication device 200. The dust bag 410 is collected in the dust collecting chamber 370 is collected.

At this time, the odor generated in the dust collecting chamber 360 when collecting the 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 A portion of the carbon (carbon) powder generated at 430 and its smell are removed by the second filter 450.

In addition, the carbon (carbon) powder and some of the odor and the odor of the motor 430 discharged through the exhaust grill 460 but not completely removed by the second filter 450 are removed while passing through the filter means 500. Will be.

That is, some carbon (carbon) powder and its odor that are not completely removed by the second filter 450 are discharged to the air outlet 461 of the exhaust grill 460 by the exhaust wind of the motor 430. Carbon (carbon) powder and its odor discharged to the air outlet 461 are introduced into the air inlet 513 formed in the front plate 511 of the air collecting container 510 and collected in the air collecting container 510. Will be.

In addition, the carbon (carbon) powder and its odor collected in the air collecting container 510 are discharged through the connecting hole 517 while hovering the air collecting container 510 together with the exhaust wind. Carbon (carbon) powder and odor discharged through) is introduced into the connection pipe (520).

At this time, when the exhaust wind flows into the connecting pipe 520, the valve bearing 700 which is installed inside the first connecting pipe 521 of the connecting pipe 520 to seal the inlet is shown in FIG. As the pressure of the exhaust wind is moved in the direction of the locking step (521a), and at the same time the carbon (carbon) powder and odor discharged through the connection hole 517 while the inlet is opened inside the connection pipe 520 Will flow into.

In addition, carbon (carbon) powder and odor introduced into the connection pipe 520 are connected to the connection pipe coupling tube 530 through the micro holes 525a of the second connection pipe 525 of the connection pipe 520. In addition to the inflow, it is introduced into the filter cylinder 540 through the first through hole 533 of the connection pipe coupling 530 and the second through hole 541 of the filter cylinder 540.

On the other hand, the pressure of the exhaust wind flows from the connecting pipe 520 to the connecting pipe coupling cylinder 530 is primarily reduced by the sponge 800 installed in the connecting pipe coupling cylinder 530 filter ( 540).

In addition, the exhaust wind and carbon (carbon) powder and the odor introduced into the filter cylinder 540 is moved through the exhaust wind air passage 545 is discharged to the outside through the exhaust port 543, wherein the exhaust The wind pressure is discharged to the outside through the exhaust port 543 in a state where the wind pressure is completely reduced secondarily by the curved surfaces of the first exhaust wind guide member 547 and the second exhaust wind guide member 549. The (carbon) powder and its odor are discharged to the outside through the exhaust port 543 in a completely filtered state by the water 900 contained in the lower part of the exhaust wind air passage 545.

Therefore, carbon (carbon) powder and its odor discharged to the outside of the main body 300 through the exhaust grill 460 during vacuum cleaning are completely filtered by the filter means 500 coupled to the rear surface of the exhaust grill 460. In this state, only the exhaust wind is discharged, thereby preventing harm to the human body and reducing exhaust noise caused by the exhaust wind.

As described above, according to the present invention, the filter means using water is coupled to be firmly fixed to the rear surface of the exhaust grill, and carbon (carbon) powder discharged to the outside of the main body 300 through the exhaust grill 460 during vacuum cleaning. Since only the exhaust wind is discharged while the odor is completely filtered by the filter means 500 coupled to the rear surface of the exhaust grill 460, it is not only harmful to the human body but also the exhaust noise by the exhaust wind is prevented. There is an effect that is reduced.
