The means for setting various functions includes not only the operation of each setting switch but also the combined operation of a plurality of switches.

Next, the selection unit 46 will be described in detail. In the present embodiment, four selection switches 46a are provided as the selection unit 46. For example, four family members can be assigned to each of these selection switches 46a to set the water supply mode for the hand-washing bowl 21 and the operation mode of the local washing device 15.

Specifically, the above three types of water supply modes can be registered for each selection switch 46a, and the operation mode of local cleaning can also be registered. By operating one selection switch 46a, a plurality of water supply modes and operation modes registered and associated with the selection switch 46a can be changed at the same time, and the subsequent local washing operation and hand washing water supply can be set. Cleaning, water supply, etc. can be performed in various manners.

The setting for each selection switch 46a can be registered by the combination operation of the user setting switch 60 of the back panel portion 36 and each setting switch. First, when the user operates and selects the desired selection switch 46a, the corresponding indicator lamp 46b is turned on. In that state, each function is set in sequence, and when the setting of the desired water supply mode and operation mode is completed, the registration is completed by performing a special operation such as pressing and holding the user setting switch 60. When the registration is completed, the indicator lamp 46b goes out. The setting information for the selection switch 46a is registered in the corresponding area of the registration unit 31. The user setting for the selection switch 46a is not limited to the above operation procedure, and may be other than that.

Further, in the present embodiment, it is possible to register the water supply modes for the two types of water supply, large / small washing, for each selection switch 46a. For example, one selection switch 46a can be set by setting the setting made after one operation of the selection switch 46a as a setting for large cleaning and setting the setting made after two consecutive operations of the same selection switch 46a as a setting for small cleaning. Settings for large / small cleaning can be registered in. Further, regarding the operation mode of the local cleaning, the operation mode of the buttocks may be set corresponding to the large cleaning, and the operation mode of the bidet may be set corresponding to the small cleaning. Of course, the local cleaning device 15 may be provided with a selection switch for local cleaning different from the selection switch 46a as a switch for individual setting.

Registration as shown in FIG. 3, for example, can be made to the selection unit 46. Since the toilet bowl device 1 of the present embodiment is provided with four selection switches 46a, the selection switches 46a can be assigned to each of, for example, four family members.

For large cleaning of the selection switch 46a (1) (corresponding to item 1 in FIG. 3), water supply interval: 3 seconds, hand wash water supply time: 10 seconds, hand wash water temperature / room temperature, butt wash, wash strength / 4 (slightly strong), cleaning width 3 (normal), and cleaning position 4 (slightly front) are set.

For small cleaning of the selection switch 46a (1), water supply interval: 3 seconds, hand wash water supply time: 5 seconds, hand wash water temperature / room temperature, bidet wash, wash strength: 2 (slightly weak), wash width: 2 (Slightly fine), cleaning position 3 (intermediate) is set.

For large cleaning of the selection switch 46a (2) (corresponding to item 2 in FIG. 3), water supply interval: 5 seconds, hand wash water supply time: 20 seconds, hand wash water temperature: 36 ° C, ass wash, wash strength.・ 2 (slightly weak), cleaning width ・ 2 (slightly thin), and cleaning position ・ 3 (intermediate) are set.

For small cleaning of the selection switch 46a (2), water supply interval: 3 seconds, hand wash water supply time: 5 seconds, hand wash water temperature: 36 ° C, bidet wash, wash strength: 1 (weak), wash width: 1 (Fine) and cleaning position 2 (slightly behind) are set.

For large cleaning of the selection switch 46a (3) (corresponding to item 3 in Fig. 3), water supply interval: 0 seconds, hand washing water supply time: 10 seconds, hand washing water temperature: 43 ° C, ass washing, washing strength・ 2 (slightly weak), cleaning width ・ 5 (thick), and cleaning position ・ 4 (slightly front) are set.

Further, for the small washing of the selection switch 46a (3), the water supply interval of 0 seconds, the hand washing water supply time of 5 seconds, and the hand washing water temperature and room temperature are set. No setting has been made for the local cleaning device 15.

For large cleaning of the selection switch 46a (4) (corresponding to item 4 in FIG. 3), water supply interval / no setting, hand washing water supply time / no setting, butt washing, washing strength / 5 (strong), The cleaning width 4 (slightly thick) and the cleaning position 3 (intermediate) are set. That is, in this setting, the water supply to the hand-washing bowl 21 is not linked to the water supply to the toilet bowl 11. Further, the water supply mode and the like are not set for the small cleaning of the selection switch 46a (4).

Such a setting becomes effective when any of the selection switches 46a is operated. That is, if any of the large / small cleaning switches 41 and 42 is operated while any of the selection switches 46a is operated, the water supply is adjusted to the selected selection switch 46a and the corresponding large and small water is supplied. Of the modes, the water supply of the corresponding water supply mode is executed. In the case of local cleaning, if any of the butt / bidet cleaning switches 51 and 52 is operated, the setting is changed to the corresponding local cleaning operation mode according to the selected selection switch 46a, and the corresponding Local cleaning of the embodiment is performed.

When any of the selection switches 46a is operated, the indicator lamps 55a, 56a, 61a, 62a, 63a corresponding to the setting switch are changed and lit to the corresponding states, and at the same time, the setting information (water supply mode, etc.) is predetermined. It is rewritten and saved in the setting information storage area of. The corresponding setting information storage area is also rewritten with respect to whether or not the hand-washing bowl 21 is linked to water supply.

Next, the operation of the control unit 30 when the water supply instruction to the toilet bowl 11 is given will be described with reference to the flowchart of FIG. As the water supply instruction means A to the toilet bowl 11, in addition to the operation of the cleaning operation unit 40 (large cleaning switch 41, small cleaning switch 42), the seating timing of the toilet seat 12 (state from on to off of the seating sensor). There is a change).

When receiving an instruction for either large or small washing, the control unit 30 controls the washing water control valve 4a to supply water to the toilet bowl 11 (S101 in FIG. 4), and supplies water to the hand washing bowl 21. Whether or not there is interlocking with the above is determined by referring to the corresponding setting information storage area (S102). If the water supply to the hand-washing bowl 21 is not linked, the process ends without automatically supplying water to the hand-washing bowl 21 (Y in S102).

If the water supply to the hand-washing bowl 21 is linked, after delaying the water supply interval by the time, the hand-washing control valve 5a is controlled to start water supply to the hand-washing bowl 21, delaying the hand-washing water supply time, and then hand-washing. The water supply to the bowl 21 is stopped (S103 to S106). Further, the hand-washing water temperature may be set by changing the heater unit 8 at the timing when the selection switch 46a is operated.

As the time interval of the delay in S103 of FIG. 4, the time interval set in the corresponding setting information storage area is used as the water supply time. That is, when the selection switch 46a is operation-selected, the information of the registration unit 31 corresponding to the selection is adopted, and when the selection switch 46a is not selected, the time interval set by the water supply interval switch 61 is adopted. Is adopted.

As the time interval of the delay in S105 of FIG. 4, the time interval set in the corresponding setting information storage area is used as the hand-washing time. That is, when the selection switch 46a is operation-selected, the information of the registration unit 31 corresponding to the selection is adopted, and when the selection switch 46a is not selected, the time interval set by the water supply interval is adopted. Will be done.

The water supply interval may be set to minus. That is, in the case of a negative setting, when a water supply instruction is given to the toilet bowl 11, water is first supplied to the hand-washing bowl 21, and after an n-second delay, water is supplied to the toilet bowl 11. Needless to say, this operation has another operation flow regardless of the flowchart of FIG.

Further, the instruction of water supply to the toilet bowl 11 at the time of leaving the seat may be determined to be large / small by detecting the length of the seating time, and the water supply may be controlled accordingly. In this case, if the seating time is longer than the predetermined time, the water supply mode and the operation mode are automatically selected based on the registration information for the large washing, and if the sitting time is less than the predetermined time, for the small washing. The water supply mode and the operation mode may be automatically selected based on the registration information of.

As described above, since the selection unit 46 can determine and register the water supply mode for each individual in the toilet device 1, the user can operate the selection switch 46a before or during the use of the toilet, and then after that. You can wash your hands according to the toilet bowl cleaning instructions. For example, the user may operate the selection switch 46a at the timing of sitting or the timing of standing up in front of the toilet bowl in the case of men's small use.

In particular, since the water supply interval can be set in various ways, water can be supplied according to different hand-washing timings for each user. For example, a user who wants to wash his / her hands after washing the toilet bowl 11 and then sits down and prepares clothes, a user who wants to wash his / her hands after washing the toilet bowl 11 and before leaving the seat, and a user who wants to wash his / her hands immediately after washing the toilet bowl 11. It can be adapted to various aspects such as a person.

In addition, since the hand-washing water supply time can be set at various time intervals, it can be set so that it is easy to use for both users who want to wash their hands easily and users who wash their hands thoroughly with soap.

Further, since the operation mode of the local washing device 15 can be registered in the registration unit 31 in combination with the water supply mode, the settings related to a series of water supply (local washing, toilet bowl washing, hand washing water supply) can be changed with one touch for each user. Can be done.

Further, since two types of registration of large / small cleaning can be assigned to one selection switch 46a, it is not necessary to provide many selection switches 46a for each large / small, and the operation of the selection switch 46a is not complicated.

In the above embodiment, there are three modes of water supply to the hand-washing bowl 21 that can be registered in the registration unit 31 (selection unit 46) for each user: water supply interval, hand-washing water supply time, and hand-washing water temperature. There may be. Further, as a water supply mode, other functions related to the hand-washing device 20 may be set.

Further, in the above embodiment, the registration unit 31 registers the water supply mode to the hand-washing bowl 21 and the operation mode of the local cleaning device 15, but in addition to the operation mode of the local cleaning device 15 or Alternatively, other function settings may be included. For example, the presence / absence of running water sound, its volume, the presence / absence of splash suppression, and the like may be assigned to the selection switch 46a. These are not started by the operation of the cleaning operation unit 40, but the sound may be generated at the timing when the selection switch 46a is operated for the running water sound, and the selection switch 46a is operated for the splash suppression. The foam may be injected at the same timing.
