  However, the cleaning water for cleaning the buttock and the bidet and the cleaning water for cleaning the cleaning nozzle are hot water of about 40 ° C. When the cleaning nozzle is retracted and stored, the hot water is not stored in the nozzle guide tube storage recess. If left, mold is likely to occur.

  For this reason, in order to suppress the occurrence of mold, the hot water is smoothly formed by forming a gap between the nozzle guide tube storage recess, the nozzle guide tube and the cleaning nozzle so that no hot water remains in the nozzle guide tube storage recess. It is necessary to be able to drain to the bowl side.

  On the other hand, when washing (cleaning) a toilet bowl with a detergent, a liquid or foam detergent is sprayed on the toilet. If the gap is large, when the toilet is washed with detergent, the detergent sprayed around the opening / closing lid passes through the gap and enters the interior beyond the recess of the nozzle guide tube storage, and dust adheres to the viscous detergent and solidifies. There is a risk of adverse effects in terms of hygiene and equipment performance due to adhesion to electronic equipment.

  On the other hand, when the gap is reduced, hot water remains attached between the inner surface of the nozzle guide tube housing recess and the nozzle guide tube and the cleaning nozzle, which may cause mold. Further, since the gap is small, a brush for cleaning the generated mold does not enter, and it is difficult to clean the mold.

  The present invention was invented in view of the above-described conventional problems, and an object of the present invention is to provide a toilet that can suppress the generation of mold and prevent dirt such as toilet cleaner from entering inside. It is in.

  In the toilet of the present invention, a local cleaning device is disposed behind the bowl portion, and a cleaning nozzle is provided so as to be freely inserted into and removed from the nozzle guide tube provided in the local cleaning device, and the cleaning nozzle is disposed in the nozzle guide tube. An open / close lid that closes in a state of retreating to hide the cleaning nozzle and opens when the cleaning nozzle protrudes into the bowl portion, and enters the tip end portion of the nozzle guide tube to enter the outer surface of the nozzle guide tube It is characterized by providing a wall for prevention.

  In addition, a nozzle guide tube storage recess that stores the nozzle guide tube and has an open end on the bowl side is provided, and both side surfaces and a bottom surface of the nozzle guide tube storage recess, and both side surfaces and a lower surface of the nozzle guide tube. A gap is formed between the side walls of the nozzle guide tube storage recess and the side surfaces of the nozzle guide tube to close the water ingress prevention wall. It is preferable that a gap between the bottom surface of the nozzle guide tube storage recess is continuous at a position below the lower end.

  Since the wall for preventing water ingress is provided at the tip of the nozzle guide tube, the wall for preventing water ingress can prevent dirt such as detergent for toilet flushing from entering the inside. Infiltration can also be prevented.
