  Here, the installation position of the steam cover 31 is described above the front end of the human body local cleaning unit 20, but it can be extended to the vicinity of the rear end of the human body local cleaning unit 20.

  Below, operation | movement of the warm water washing toilet seat 1 of this invention is demonstrated.

FIG. 3 is a block diagram illustrating the flow of water. Water supplied from a water supply source 5 having a water pressure such as water supply passes through the water stop valve 53 for the hot water tank unit controlled by the control board 51 and is heated to about 40 ° C. in the hot water tank unit 10. Then, the flow rate is adjusted by the first flow rate adjusting valve 26 and is injected as hot water from the human body local washing unit 20 to the human body local part. The water supplied from the water supply source 5 passes through the water stop valve 54 for the steam generation unit controlled by the control board 51 and passes through the second flow rate adjustment valve 52 after a predetermined time has elapsed after the hot water injection to the human body is completed. Then, the flow rate is adjusted to 0.5 cm ³ / s or less, and the steam generation unit 40 converts the flow rate into dry steam that does not contain liquid, and the spray is sprayed from the cleaning nozzle unit 30 to the tip of the human body local cleaning unit 20 as dry steam. At this time, the control board 51 energizes the sheathed heater 43 with about 20% more heat than the amount of heat required to make the water sent from the second flow rate adjustment valve 52 dry steam with the steam generation unit 40.

FIG. 4 is a timing chart of water flow to the steam generation unit 40 and energization. The control board 51 stops spraying (a) after injecting warm water of about 40 ° C. from the buttocks cleaning nozzle 21, and stores the buttocks cleaning nozzle 21 in the main body 2 of the warm water cleaning toilet seat 1 with a motor, Operate and deliver (b) water at a flow rate of 0.5 cm ³ / s or less to the steam generation unit 40. At the same time, the control board 51 energizes (b) the sheathed heater 43 of the steam generation unit 40. The steam generation unit 40 instantaneously vaporizes all of the supplied water into dry steam, and sends it to the steam nozzle 32 for the throat nozzle. The steam injection port 32 for the buttocks nozzles jets the fed steam to the tip of the buttocks nozzle 21 to clean the tip of the buttocks nozzle 21. After injecting steam from the steam generation unit 40 for 30 seconds, the control board 51 stops (c) energization of the sheathed heater 43 and, at the same time, reduces the amount of water delivered from the second flow rate adjustment valve 52 to the steam generation unit 40. The steam generation unit 40 is cooled by increasing the pressure to ⁵ cm ³ / s or more, and the second flow rate adjustment valve 52 is stopped (d) after 10 seconds. In the present embodiment, the vapor injection time is set to 30 seconds, but the user can arbitrarily change the injection time depending on the state of attachment of the filth. Similarly, the cooling time until the second flow rate adjustment valve 52 is stopped is 10 seconds, but it is possible to change the time according to the capacity of the steam generation unit and the cooling efficiency change.

  The operation of the bidet cleaning nozzle 23 is the same.

  Here, after the buttocks cleaning nozzle 21 is stored in the main body 2 of the hot water cleaning toilet seat 1 by the electric motor 25 or the bidet cleaning nozzle 23 is stored in the main body 2 of the hot water cleaning toilet seat 1 by the motor. In the above description, a series of operations from the start to the stop of the operation of the second flow rate adjusting valve 52 is described. However, the user can substitute the button by pressing the buttocks cleaning nozzle cleaning switch or the bidet cleaning nozzle cleaning switch. It is.

  Below, the effect of the warm water washing toilet seat 1 of this invention is demonstrated.

  The warm water flush toilet seat 1 of the present invention first stops energization of the steam generation unit 40, and then stops water flow to the steam generation unit 40 after a predetermined time has elapsed, thereby causing thermal deformation and ignition of the resin main body 2. Can be prevented. Furthermore, by making it possible to change the amount of water flow to the steam generation unit 40, the amount of water flow is reduced during steam generation while the steam generation unit 40 is energized, and the generated steam is clustered into large particles. It is possible to obtain a dry vapor that is completely gasified and atomized without containing the heated hot water. This makes it easy for the vaporized fine particles to permeate inside the filth such as manure and scale adhering to the tip of the buttocks nozzle 21 or the tip of the bidet nozzle 23, and crushing and peeling the filth with steam having a weight less than that of hot water. Alternatively, it can be dissolved and removed. By being able to wash with steam having a weight less than that of hot water, it becomes possible to further prevent the accumulated heat deterioration of the buttocks nozzle 21 or the bidet nozzle 23. It is also possible to obtain a sterilizing effect at the tip of the butt nozzle 21 or the tip of the bidet nozzle 23.

  In addition, by using a pump capable of pumping water even in a high-pressure environment such as the second flow rate adjustment valve 52, even if a request for generating high-pressure steam in the steam generation unit 40 is issued from a user or a seller, Water from the water supply source 5 can be fed into the steam generation unit 40 against the steam pressure. Thereby, it becomes possible to inject vapor | steam more reliably to the human body local cleaning unit 20, and also it becomes possible to raise cleaning power.

  Moreover, the warm water washing toilet seat 1 of this invention fastens the steam generation unit 40 to the main body 2 of the warm water washing toilet seat 1 via the heat insulating body 45, and the effect which prevents the thermal deformation of the resin-made main body 2 improves. .

  Moreover, the warm water washing toilet seat 1 of the present invention first stops energization to the steam generation unit 40, and then stops water flow to the steam generation unit 40 after a predetermined time has elapsed, thereby thermally deforming the resin-made main body 2. Can be prevented.
