Abstract

The purpose of the invention is to provide a range hood that can efficiently emit ultraviolet light to a filter regardless of oil smoke or the like flowing in the hood, that prevents people in the room from experiencing bad odors, and that does not allow ozone to fill a room. A range hood comprises a hood (2), a filter (3), a blower (4) that rotates a fan (42) with a fan motor (43), an ultravioletlight source (5) that emits ultraviolet light on the filter (3), and a control unit (7) that controls the fan motor (43) and the ultraviolet light source (5). The control unit (7) illuminates the ultraviolet light source (5) for a set time after stopping operation from an operating state and simultaneously rotates the fan (42) while the ultraviolet light is being emitted by driving the fan motor(43) for the set time.

Description

technical field [0001] The present invention relates to a cooker hood which collects and discharges cooking fumes and the like generated during heating and cooking. Background technique [0002] In the past, as a cooker hood, the following range hood is known. That is, the range hood includes a cover, a filter, and a blower. After the filter removes oil from the collected cooking fumes, etc., the cooking fumes and the like are discharged outside the house, etc. [0003] In the range hood as described above, oil adheres to the filter to make the filter dirty, so the dirty filter is replaced with a new filter, or the dirty filter is cleaned. However, filter replacement work and filter cleaning work are troublesome. [0004] Therefore, a range hood has been proposed that irradiates ultraviolet rays to the filter when the blower is driven, that is, when the range hood is in operation, thereby decomposing and removing the oil adhering to the filter (for example, refer to Patent...
