Abstract
A method for removing odors produced in a toilet main unit of a toilet is made available. Specifically, a deodorizing unit having an air expulsion port and an air suctioning port is provided in a rear portion of the toilet main unit, and air is circulated by expelling air through the expulsion port such as to laterally swirl the air along an inner surface of the toilet's bowl, and by suctioning swirled returning air via the suctioning port. Deodorization is carried out in the course of circulating the air.
Claims7
A deodorizing method for removing odors within a flush-toilet toilet bowl, the deodorizing method comprising:
- providing, in a rear portion of a toilet main unit, a deodorizing device having an air expulsion port and an air suctioning port;
- circulating air by expelling air through the expulsion port toward a lateral inner surface of the toilet bowl to laterally swirl the air along an inner surface of the toilet bowl, and suctioning swirled returning aft via the suctioning port;
- and carrying out deodorization in the course of circulating the air.
A deodorizing device for removing odors within a flush-toilet toilet bowl, the deodorizing device comprising:
- a deodorization passage, provided in a rear portion of a toilet main unit, having at one end thereof an air expulsion port, having at another end thereof an air suctioning port, and furnished midway thereof with a deodorizing section;
- and
- a blower enabled for generating a flow of air in the deodorization passage;
- wherein the expulsion port is arranged so as to open toward a lateral inner surface of the toilet bowl to enable air expelled therefrom to swirl laterally along an inner surface of the toilet bowl, and the suctioning port is arranged so as to open on a flow pathway of air returning from swirling along the toilet bowl.
A flush toilet furnished with a deodorizing device for removing odors within a main unit of the toilet, the deodorizing device comprising:
- a deodorization passage, provided in a rear portion of a toilet main unit, having at one end thereof an air expulsion port, having at another end thereof an air suctioning port, and furnished midway thereof with a deodorizing section;
- and
- a blower enabled for generating a flow of air in the deodorization passage;
- wherein the expulsion port is arranged so as to open toward a lateral inner surface of the toilet bowl to enable air expelled therefrom to swirl laterally along an inner surface of a bowl of the toilet, and the suctioning port is arranged so as to open on a flow pathway of air returning from swirling along the toilet bowl,
- wherein the flush toilet is configured to enable an air-swirling passage within the toilet bowl, and said deodorization passage to form a circulation passage for circulating air, and
- wherein the swirling passage is configured by a rim-like pathway formed in an upper portion of the toilet main unit.
A deodorizing method for removing odors within a flush-toilet toilet bowl, the deodorizing method comprising:
- providing, in a rear portion of a toilet main unit, a deodorizing device having an air expulsion port and an air suctioning port;
- generating a flow of air so as expel the air through the expulsion port toward a lateral inner surface of the toilet bowl such as to laterally swirl the air along an inner surface of the toilet bowl, and to suction swirled returning air via the suctioning port;
- and carrying out deodorization in the course of generating the flow of air.
