Title: Electric vacuum cleaner
Inventor: MURAKAMI MINORU
IPC: A47L7/00
Filed: 1989-10-07
Abstract: PURPOSE:To sufficiently kill harmful microbes without excessively raising the temperature of an electrically-driven air blower by disposing a far infrared ray radiator within the chamber of dust collecting chamber of warm air circulating channel of exhaust air from the electrically-driven air blower. CONSTITUTION:A far infrared ray radiator 26 is disposed within a dust collecting chamber 18 by mounting a return current channel communicating with the dust collecting chamber. Then when the exhaust side of an electrically- driven air blower is connected to the dust chamber, and the electrically-driven air blower is driven, heated exhaust air is sent back to the dust collecting chamber through return current channel to kill harmful microbes in the dust collecting chamber. At this moment, the far infrared ray radiator in the dust chamber absorbs thermal energy from the heated air stream, and emits it in the form of far infrared ray. Since far infrared ray penetrades into organisms with ease, harmful microbes can be effectively killed at rather low temperature, and the motor of the air blower needs not to be over-heated. Besides even when the electric air blower is turned off at an earlier time, the far infrared ray, which continues to be radiated from the accumulated far infrared ray radiator will never fail to kill harmful microbes.
