The dust chamber cover may be opened by pressing the button hanger to lift the dust chamber cover away from the button hanger.

At this time, an open holding rib (not shown) formed at the main body 100 side and an open holding rib catching part (not shown) having an extended rear bent portion of the hinge coupling part of the dust collecting chamber cover are opened. It maintains the state. If the dust chamber cover is kept open, the dust collecting assembly is separated.

Then, the dust of the dust collecting bag 170 is removed, and the dust collecting assembly to which the dust collecting bag 170 is coupled is rearranged to a filter mount (not shown) fixed to the dust collecting chamber. When the upper surface of the dust chamber cover in the open state is pushed as described above, the dust chamber cover is closed.

According to the present invention as described above, there is an advantage that the friction noise generated by the vibration of the fast rotational force of the fan motor 210 is prevented.

The scope of the present invention is not limited to the above-exemplified embodiments, and many other modifications based on the present invention may be made by those skilled in the art within the above technical scope.

For example, in the above embodiment, the receiving portion 115 of the upper surface of the body base 110 and the fixing protrusions 205 of the lower portion of the motor housing 200 are formed in pairs on both sides. It is also possible to further form a pair of receiving portion to the side, so that the fixing projection further formed on the lower portion of the motor housing 200 corresponding thereto.
