First and second ribs 822 and 823 of size are formed.

In addition, the inner parts of the third cover 83 are different from each other to prevent the vibration caused by the driving of the vacuum motor M1 and to reduce noise while supporting the side portions when the vacuum motor M1 is seated. Third and fourth ribs 832 and 833 of size are formed.

In this case, the first rib 822 is the same shape as the third rib 832, and the second rib 823 is configured in the same shape as the fourth rib 833.

In addition, the second and third covers 82 and 83 are each provided with leg portions 824.

In this case, the soundproof pad 85 is configured on the bottom surface of the main body 100 to block the noise during the driving of the vacuum motor M1 while allowing the leg portion 824 to be raised.

The air discharge grill 84 discharges the air sucked into the vacuum motor M1 from the air suction grill 811 of the front cover 812 of the first cover 81 in an inclined direction at a predetermined angle. By reducing the noise generated during the air discharge, it is coupled to the grill coupling portions 821 and 831 of the second and third covers 82 and 83 so as to be detachable.

At this time, the horizontal grill walls 841 of the air discharge grill portion 84 is preferably configured to have a constant inclination angle (for example, 45 °) to guide the air discharge in the inclined direction upward at a predetermined angle, but not necessarily The inclination angle is not limited to the inclination angle, and the inclination angle can be changed as a state to face upward.

The dust collecting container 100 is made of a transparent body to make it possible to easily identify the dust collection state of the foreign matter, as well as to easily identify the sewage time of the filter to the outside, one side of the cover to rotate around the hinge 101 is configured, and on the other side, the filter network 102 and the HEPA filter 103 are coupled to each other.

At this time, the HEPA filter 103 is a high-performance dust collection filter that removes at least 0.3 micron particles (eg, dust, bacteria, viruses), and purifies the collected polluted air and discharges it into the room.

Although the insect repellent is not shown in the figure, it may be integrally configured in the main body 10 of the vacuum cleaner or may be configured to be detachable as a module. As shown in FIG. 10, an output mode selection key 91 is provided. , An ultrasonic generator 92, and an ultrasonic output unit 93.

The output mode selection key 91 is configured to select the output mode of the ultrasonic wave in the form of a push switch and then output the selection signal to the microcomputer 200.

The ultrasonic generator 92, when the control operation of the microcomputer 200 from the output mode of the ultrasonic wave selected by the output mode selection key 91, ticks, fleas, crawling pests, cockroaches and flying insects, mice And ultrasonic waves in the range of 1-50 kHz to combat outdoor harmful algae such as wind rats and blue bristles.

The ultrasonic output unit 93 is configured to output a certain level of ultrasonic waves generated from the ultrasonic generator 93 to the outside to apply stress that the pest can not withstand.

That is, the vacuum cleaner according to the embodiment of the present invention, as shown in Figures 1 to 5 and 10 attached, first the mode switch in the state in which the user switched on the power switch 41 of the power switching unit 40 ( Use 42) to select the operation mode.

At this time, the operation mode of the mode switch 42 is switched according to the number of times the user presses the mode switch 42, the operation mode is the first mode, the vacuum motor (M1) for operating the vacuum motor (M1) ) And the second mode of operating the ultraviolet lamp 50, the third mode of operating the vacuum motor M1 and the brush motor M2, the vacuum motor M1 and the brush motor M2 and the ultraviolet lamp 50. The fourth mode of operating and the fifth mode of operating the ultraviolet lamp 50.
