Abstract

PROBLEM TO BE SOLVED: To provide a device which deodorizes a toilet room and a toilet bowl without connecting to a commercial power supply by utilizing a vacuum water drain system. SOLUTION: A vacuum pipe 3 is connected with a Western-style toilet bowl 2 in a toilet room 1, and deodorizing pipes 12, 13 which are branched from the vacuum pipe 3 are communicated with a bowl 2a and an air exhaust port 16 through deodorizing valves 14, 15. When a user sits on a stool 4, the valves 14, 15 are opened for deodorization, and a generator 11b generates power. Generated electricity is charged into a battery of a control device 22. Consequently, it is possible to exhaust odor from the stool and the toilet room efficiently by utilizing negative pressure of the vacuum pipe. The connection with a commercial power supply is unnecessary.
