In addition, the main body is formed by the combination of the upper case 41 and the lower case 21.

Next, the operation and effect of the noise device of the vacuum cleaner of the present invention configured as described above will be described.

First, when the main switch (not shown) is turned on, the suction motor 31 is operated to suck dust and air into the dust collecting chamber 211 through the pipe member 26 and to the dust collecting chamber 211. The sucked dust is collected in a dust collecting bag (not shown), and the filtered air is sucked into the suction motor 31 and exhausted to the outside.

At this time, the suction motor 31 generates noise due to the operation of the suction motor 31, and a part of the noise generated by the suction motor 31 is partially supported by the support 23. It is radiated to the dust collecting chamber 211 through the longitudinal lattice 122 formed in the suction hole 231, the suction hole 111 of the sound absorbing member 11 and the protrusion 123 of the cover member 12, Dust collection room 211 Radiated noise is reflected inside the dust collection room 211 through the radial grating 121 formed in the cover member 12 of the noise means (10) the sound absorbing member The sound absorbed by (11) can attenuate the noise generated by the suction motor 31.

That is, the noise generated by the suction motor 31 and radiated to the dust collecting chamber 211 is absorbed by the noise means 10 without being radiated to the outside through the pipe member 42. The sound of the suction motor 31 is attenuated by being absorbed by the member 11.

In addition, when the suction motor 31 is operated and dust and air are sucked into the dust collecting chamber 211 through the pipe member 42, the dust is collected in a dust collecting bag (not shown) and the dust filtered air is sucked in. Suction motor 31 is sucked by the suction force of the motor (31).

At this time, the air sucked into the suction motor 31 is minimized the carriage resistance is rectangular grid 122 formed in the protrusion 123 of the cover member 12 along the streamlined surface formed on the front surface of the cover member 12 Flows into).

That is, the air flowing into the rectangular lattice 122 formed in the protrusion 123 of the cover member 12 flows into the rectangular grid 122 along the streamline of the cover member 12, so that frictional resistance of air is caused. The noise due to the flow rate of the air is minimized, as a part of the noise generated by the flow rate of the air is absorbed by the sound absorbing member 11 through the plurality of radial gratings 121 formed on the cover member 12. Attenuate (騷 音).

In addition, a part of noise generated by the flow rate of air that is not sucked into the sound absorbing member 11 is reflected by hitting the inner wall of the dust collecting chamber 211, so that the noise means 10 Is absorbed by the sound absorbing member 11.

That is, the sound-absorbing member 11 of the noise means 10 does not radiate to the outside through the pipe member 42 even when noise caused by the suction flow generated in the dust collecting chamber 211. The sound absorbed by) decreases the noise caused by the intake flow.

In addition, a protrusion 123 having a plurality of rectangular grids 122 into which air is introduced is formed at the center of the cover member 12 so that a large amount of air is provided in the rectangular grid 122 of the protrusion 123. Since the vortex does not occur even if it is introduced, it is possible to supply more air to the suction motor 31.

As described above, according to the vacuum cleaner of the present invention, the suction member of the noise means absorbs the noise generated by the suction of air such as noise and dust generated from the suction motor. By reducing the noise more effectively, the quality of the vacuum cleaner can be improved.
