9) Since hot water is accommodated which is superheated by.

Inside the water heater (4), the amount of water supplied through the AiJ Kiharahi raw water supply pipe 3) is increased, so this increased amount of hot water is used for washing in the hot water distribution chamber (7) in the hot water storage toilet seat (2). 1. Hot water is sucked into the pipe through the hot water inlet (5o) fixed upward at the center of the tip of the toilet seat itself.
The hot water suction pipe (49) passes through the through hole (51) of the interlocking shaft (35), and further communicates with the hot water supply side joint pipe (4).
6), through the hot water spout pipe (48), and the hot water spout pipe (48).
8) from a shower nozzle (18) protruding from the tip. The amount of hot water for cleaning spouted from the shower nozzle (18) is determined by the flow rate adjustment valve (15) installed in the raw water supply path.
It can be arbitrarily adjusted by In addition, even if the flow rate adjustment of the flow rate adjustment valve (15) is set to the minimum in order to prevent forgetting to stop the water supply pump, the shower nozzle (18) will eject a flow rate that does not splash hot water on the buttocks. It is configured so that

Since the sanitary cleaning device according to the present invention has a soft soil structure, it can significantly exhibit various excellent effects as described below.

a) Since the toilet seat itself is a hot water storage toilet seat having a hot water circulation chamber inside, the water heater can be small and the device can be made compact. Therefore, even in a small toilet, a compact device can provide an abundance of hot water for private washing.

b) The second toilet seat itself is a hot water storage toilet seat that has a hot water distribution chamber inside, and the rear part of the hot water storage toilet seat is made into a cylindrical shape so that it can communicate with the electric water heater, so that no fluid flows between the hot water storage toilet seat and the electric water heater pipe. Since hot water is constantly circulated by actively generating natural convection caused by temperature differences, this hot water not only heats the toilet seat, but also provides the unique and comfortable warmth of hot water that cannot be obtained with conventional dupping heaters. You can see the top of the toilet seat.

C) Since the hot water spouting machine is integrally installed in the hot water storage toilet seat, the hot water spouting machine, such as the cylindrical bearing and the hot water spouting pipe, are in contact with the constantly heated toilet seat, and the water in the hot water spouting pipe is in contact with the heated toilet seat. The warm water maintains an appropriate temperature, and the short distance to the tip of the shower nozzle prevents cold water from coming out at the beginning of spraying from the shower nozzle, so you can wash your private parts with peace of mind.

d) Since the hot water jetting device is integrated with the hot water storage toilet seat, the hot water jetting device, together with the hot water storage toilet seat, is separated from the top of the toilet bowl during men's errands, and there are no protrusions on the inner periphery of the toilet bowl. , it is very hygienic as it does not easily get urinated.
