Vacuum cleaner

1. A vacuum cleaner, comprising:

a cleaner body in which a ultraviolet (UV) irradiation unit is mounted in a dust receptacle mounting unit;

a dust receptacle detachably mounted in the dust receptacle mounting unit, the dust receptacle comprising a UV transmission window formed in a position facing the UV irradiation unit; and

a switching device mounted in the dust receptacle mounting unit to switch power applied to the UV irradiation unit according to whether the dust receptacle is mounted, wherein the switching device comprises:

a switching member protruding from the dust receptacle mounting unit in a position facing the dust receptacle;

a switching projection protruding from the dust receptacle in a position facing the switching member, so that pressure is applied to the switching member when the dust receptacle is in a mounting position; and

a guide rib extending from a circumference of the switching member to guide movement of the switching projection.

2. The vacuum cleaner as claimed in claim 1 , wherein the UV transmission window is configured with an opening disposed in a position facing the UV irradiation unit of the dust receptacle mounting unit, and with a fluoropolymer film attached to the opening.

3. The vacuum cleaner as claimed in claim 1 , wherein the UV irradiation unit comprises:

a UV lamp; and

a protection grill configured to house the UV lamp.

4. A vacuum cleaner comprising:

a cleaner body in which a ultraviolet (UV) irradiation unit is mounted in a dust receptacle mounting unit;

a dust receptacle detachably mounted in the dust receptacle mounting unit, the dust receptacle comprising a UV transmission window formed in a position facing the UV irradiation unit;

a lifting unit to move the dust receptacle upwards or downwards; and

a switching device mounted in the dust receptacle mounting unit to switch power applied to the UV irradiation unit according to vertical movement of the dust receptacle, wherein the switching device comprises:

a switching member protruding from the dust receptacle mounting unit in a position facing the dust receptacle;

a switching projection protruding from the dust receptacle in a position facing the switching member so that pressure is applied to the switching member when the dust receptacle is in the mounting position; and

a guide rib extending from a circumference of the switching member to guide the ascent and descent of the switching projection.

5. The vacuum cleaner as claimed in claim 4 , wherein the lifting unit comprises:

an adjustment lever to rotate to adjust the extent of a mounting position of the dust receptacle; and

a lifting board to move the dust receptacle upwards or downwards according to a change in the mounting position of the dust receptacle adjusted by the adjustment lever.

6. The vacuum cleaner as claimed in claim 4 , wherein the guide rib restricts further ascent of the switching projection when the dust receptacle reaches the highest point.

7. The vacuum cleaner as claimed in claim 4 , wherein the UV transmission window is configured with an opening disposed in a position facing the UV irradiation unit of the dust receptacle mounting unit, and with a fluoropolymer film attached to the opening.

8. The vacuum cleaner as claimed in claim 4 , wherein the UV irradiation unit comprises:

a UV lamp; and

a protection grill wherein to house the UV lamp.
