1. A vacuum cleaner, comprising:
- a housing comprising a bottom, a top and a side interconnecting the top and the bottom;
at least one bottom opening formed in the bottom of the housing;
a cavity formed in the housing in fluid communication with the at least one bottom opening;
an ultra violet light source configured to irradiate ultra violet light to a surface under the bottom;
a hitting duster configured to beat the surface under the bottom;
means for forcing air in a direction within the housing to form a negative pressure in the cavity such that an air flow can be made through the at least one bottom opening from outside the housing to the cavity during operation of the vacuum cleaner;
at least one auxiliary opening formed on at least one of the side and the top, wherein the at least one auxiliary opening is also in fluid communication with the cavity such that a substantial air flow is made through the at least one auxiliary opening from outside the housing to the cavity as a negative pressure is formed in the cavity, even if the at least one bottom opening is completely blocked during operation of the vacuum cleaner; and
wherein the at least one auxiliary opening is provided by a plurality of ribs formed on the at least one of the side and the top of the housing.

Abstract
The sterilizing vacuum cleaner for bed clothes includes a housing including an ultraviolet (UV) irradiating space depressed into a bottom surface thereof, a suction port formed in the UV irradiating space, a discharge port formed in a side surface thereof, an air passage for connecting the suction port and the discharge port, and a sticking prevention passage depressed into the bottom extending to the side surface to prevent an object to be sterilized from adhering to the bottom surface. A first UV light emitter is installed in the housing to irradiate ultraviolet rays to the UV irradiating space of the housing.

12. A method of vacuum cleaning, comprising:
-
providing a vacuum cleaner comprising; a housing comprising a bottom, a top and a side interconnecting the top and the bottom, at least one bottom opening formed in the bottom of the housing; a cavity formed in the housing in fluid communication with the at least one bottom opening, an ultra violet light source configured to irradiate ultra violet light to a surface under the bottom, a hitting duster configured to beat the surface under the bottom, means for forcing air in a direction within the housing to form a negative pressure in the cavity such that an air flow can be made through the at least one bottom opening from outside the housing to the cavity during operation of the vacuum cleaner, and at least one auxiliary opening formed on at least one of the side and the top, wherein the at least one auxiliary opening is also in fluid communication with the cavity such that a substantial air flow is made through the at least one auxiliary opening from outside the housing to the cavity as a negative pressure is formed in the cavity, even if the at least one bottom opening is completely blocked during operation of the vacuum cleaner, wherein the at least auxiliary opening is provided by a plurality of ribs formed on the at least one of the side and the top of the housing; placing the vacuum cleaner over a surface such that the bottom faces the surface to clean; and operating the vacuum cleaner so as to create a negative pressure in the cavity, thereby sucking dust and particles into the cavity from the surface via the at least one bottom opening, and thereby creating a substantial air flow into the cavity via the at least one auxiliary opening. - View Dependent Claims (13, 14, 15, 16, 17)
