- the cleaning selection means 1 2 3 can be used to selectively set the cleaning nozzle according to the purpose of use and taste, for example, equivalent to water or local cleaning water.
- the washing water at various temperatures can be selected and used, such as 40 ° C washing water, 7 ° C high-temperature water, and steam exceeding 100 ° C.
- the cleaning operation is performed when a selection operation is performed by the cleaning selection means 123, and the cleaning operation is prohibited during the seating detection. It is safe because cleaning is performed only by non-sitting and conscious operation, and hot water does not come out while sitting.
- a heat exchange chamber 127 having a larger cross-sectional area than the inlet water is formed in the center of the area where the heater 119 is disposed.
- Heat can be heated with high heat exchange efficiency while preventing pressure rise at 7, and the heat exchange chamber 1 27 is divided into multiple spaces by weirs 12 9 and filled with metal fibers 13 Exchange efficiency can be further improved and clean steeple System can occur.
- the basic configuration is the same as that of the first and second embodiments, but in this embodiment, the safety of the nozzle cleaning operation using high-temperature cleaning water is further improved.
- a non-volatile memory for storing the accumulated time of operating the nozzle cleaning mode is connected to the control units 23 and 121, and reset means is provided for resetting the accumulated value.
- the control units 23 and 121 include a signal indicating whether or not a human body is seated on the toilet seat, a signal regarding the temperature of the washing water, and a signal regarding the flow rate of the washing water. Is entered.
- the warm water flush toilet seat 230 having the above circuit configuration is provided with a toilet seat 2332 and a toilet seat 232 attached to a main body 231, which is fixed to the rear of the upper surface of a toilet (not shown).
- the upper toilet lid 2 3 3 is mounted so that it can be opened and closed vertically.
- An operation unit 234 is disposed on one side of the main unit 231, and an operation command signal is input to the control units 231 and 221.
- the operation unit 2 3 4 has a bottom cleaning switch 2 3 5 for selecting and setting the bottom cleaning mode, a bidet cleaning switch 2 36 for selecting and setting the bidet cleaning mode, and cleaning nozzles 17, 18, 1 1.
- the high-temperature cleaning switch 237 is provided in a recess 239 formed on the upper surface of the operation unit 234, and the switch cannot be operated unless it is pushed with a finger. The switch is not accidentally operated by touching the hand.
- the nozzle cleaning mode is selected and set when the high-temperature cleaning switch 237 and the posterior cleaning switch 235 are simultaneously pressed for a certain period of time or longer. As shown in Fig.
- a seat / high-temperature washing switch 240 that combines the buttocks washing switch and high-temperature washing switch is provided, and the seating state is detected by the seating detecting means 222. Pressing the buttocks / high-temperature washing switch 240 while detecting a condition may select and set the buttocks washing mode, and press and hold the switch while not seated to select and set the high-temperature washing mode.
- the control unit 23, 121 sends the buttocks from the washing nozzles 17 and 1 16 to the local area. A desired temperature and a desired amount of cleaning water are blown out to perform cleaning.
- washing water is similarly blown out from the bidet washing nozzles 18 and 117 toward the local area to perform washing.
- the operation mode becomes the nozzle cleaning mode, and the high-temperature cleaning water is discharged to the tip outer surfaces of the posterior cleaning nozzles 17 and 1 16 and the bidet cleaning nozzles 18 and 1 17 so that the cleaning nozzle 17 , 1 8, 1 16, 1 17
- the dirt on the outer surface of the tip is surely cleaned, and good hygiene is ensured.
- the detection signal is output from the seating sensors 25 and 124, so operation in the nozzle cleaning mode is prohibited, and safety can be ensured. it can. Also, if the flow rate of the washing water is set small in the nozzle washing mode, the seat sensors 25 and 124 Even if the nozzle cleaning mode is selected in the operating state, the high-temperature cleaning water is strongly jetted out and scattered, and there is no danger that the high-temperature cleaning water will be applied to a local part of the human body, thus ensuring high safety.
- the cleaning nozzle cleaning mode when the operation of the nozzle cleaning mode is stopped, if the cleaning water at the temperature at the time of the local cleaning is supplied for a certain period of time, the cleaning nozzles 17 and 17 Since the cleaning water at the temperature at the time of the normal local cleaning is replaced in 18, even if the normal local cleaning is immediately performed, the high-temperature cleaning water is not discharged, so that it is safe.
- the generation of high-temperature cleaning water may cause scales in the heat exchangers 12 and 120 to damage the apparatus. If the cumulative operation time of the nozzle is stored in the non-volatile memory 222 and the operation of the nozzle cleaning mode is prohibited when the cumulative operation time exceeds a predetermined value, a problem that may cause a failure in the apparatus due to the generation of scale may be caused. It can be prevented before it happens. In addition, after performing the maintenance and inspection to eliminate the possibility of such an adverse effect, it is possible to easily return to the original state by resetting the accumulated value by the resetting means 224.
- the cleaning nozzles 17, 18, 116, 117 are moved out and back by a mechanical moving mechanism, but as the nozzle units 16, 115, A cleaning nozzle for ejecting cleaning water to a local part of the human body is supported between the cleaning position and the standby position so as to be able to move back and forth, and is urged to move toward the standby position so that the cleaning water is supplied at a predetermined flow rate or more. Then, the cleaning nozzle protrudes to the cleaning position and sprays the cleaning water toward the local area (not shown; refer to Japanese Patent Application Laid-Open No. 2001-152825).
- the temperature of the cleaning water for nozzle cleaning for cleaning the outer surface of the cleaning nozzle is higher than the temperature of the cleaning water for local cleaning by the heating device. It is suitable for surely cleaning dirt adhering to the cleaning nozzle and ensuring good hygiene.
- control unit that detects and controls the presence or absence of the human body sitting on the toilet seat, the amount of flushing water flowing, the temperature of the flushing water heated by the heat exchanger, etc., and a dedicated switch to select various flushing modes. Because of the provision of an operating unit, it is suitable for preventing the danger of high-temperature washing water being used during local washing and ensuring high safety.
