12 is a cross-sectional view showing a combined state of a suction unit and a suction unit housing of a cleaner according to an embodiment of the present invention. Reference numerals not shown refer to FIGS. 1 to 11. Hereinafter, descriptions overlapping with those of FIGS. 1 to 11 may be omitted.

As shown in FIG. 12, a flow path 870 may be formed in the suction unit housing 800.

The flow path 870 may include at least one bent portion 871 so that air that has passed through the suction unit 100 can be refracted and exhausted.

In addition, at least one sound absorbing material (not shown) may be disposed on the flow path 870.

The at least one sound absorbing material (not shown) may include a first sound absorbing material (not shown) and a second sound absorbing material (not shown).

The flow path 870 may include a first flow path 870a and a second flow path 870b.

Specifically, the air discharged from the suction unit 100 is delivered to the second sound absorbing material (not shown) through the through hole 831 of the extension part 832 formed in the third housing 830. The air that has passed through the second sound absorbing material (not shown) moves along one side 810b of the first housing 810, passes through the exhaust slit 823a of the second housing 820, and is mounted on the sound absorbing material seating part 823 It is delivered to the first sound absorbing material (not shown). The air that has passed through the first sound absorbing material (not shown) is discharged to the outside of the suction unit housing 800.

As the air discharged from the suction unit 100 passes through at least one bent portion 871, the straightness is hindered. That is, as the air discharged from the suction unit 100 passes through at least one bent portion 871, the moving direction changes. Accordingly, it is possible to increase the path through which the noise generated by the suction unit 100 is transmitted to the body, and as a result, it is possible to prevent the noise generated by the suction unit 100 from being directly transmitted to the body.

The flow path 870 may be variously changed according to the shape or arrangement structure of the suction unit housing 800.

The suction unit housing 800 according to the present invention can be applied regardless of the type of vacuum cleaner. That is, the suction unit housing 800 according to the present invention can be applied to various types of vacuum cleaners such as a canister-type cleaner, an upright-type cleaner, and a robot cleaner.
