DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle mechanism for a hot water flush toilet seat.

[0002]

2. Description of the Related Art A nozzle mechanism of a conventional hot water flush toilet seat is disclosed in, for example, JP-A-61-142237. In this conventional apparatus, at the time of cleaning,
Even if the flow rate or injection amount of the washing water changes, the washing area is appropriately changed so as not to give a user a sense of incongruity.

[0003]

However, in the conventional apparatus, when the flow rate is small (large), that is, when the cleaning water pressure or the injection water pressure is high (low), the cleaning area becomes narrow (wide). Therefore, hemorrhoids could not meet the desire to clean the vicinity of the anus with a large flow rate (low washing water pressure) over a wide range.

[0004] Therefore, an object of the present invention is to provide a nozzle mechanism for a hot water flush toilet seat that can meet such demands.

[0005]

Means for Solving the Problems In order to solve the above-mentioned technical problems, the technical means adopted in the first aspect of the present invention is to provide a first jet port and a second jet port for independently injecting cleaning water into a tip portion. A nozzle provided with an ejection port, an ejection control means for injecting the washing water from one or both of the first ejection port and the second ejection port, and a position adjusting mechanism for adjusting the position of the nozzle. That is, the nozzle mechanism of the warm water flush toilet seat provided is configured.

[0006]

According to the first technical means, in the case where a human body part to be cleaned is to be cleaned with only the cleaning water from one of the first and second jet ports, the selected jet port can be cleaned. Since it is possible to surely aim the cleaning portion, the cleaning can be accurately performed, and when the cleaning water is jetted from both the first jet port and the second jet port, both the jet portions are cleaned. So that it is located in the middle of the exit,
Extensive local (particularly anal) irrigation can be performed with low irrigation water pressure.
