However, since the timing of handwashing differs from person to person, the preset coordination of water supply to the toilet bowl and water supply to the handwashing bowl does not allow all users to use one toilet device when multiple users use it. It does not necessarily mean that it is easy for the user to use. For example, there are people who want to wash their hands at the same time as cleaning the toilet bowl, and people who want to wash their hands after cleaning the toilet bowl and adjusting their clothes. will not be satisfactory.

Furthermore, since the amount of hand washing water varies from person to person, if a fixed hand washing water supply time is set according to the case where a large amount of hand washing water is required, the water supply amount will be wasted for people who only need a small amount of hand washing water.

In other words, there are various modes of cooperation between the water supply to the toilet bowl and the water supply to the hand-washing bowl, as well as the water supply time of the hand-washing water supply. It is more desirable to be able to choose.

The present invention was proposed in consideration of such circumstances, and its purpose is to provide a toilet device with a handwash basin that can supply water to a handwash bowl in a desired water supply manner with individual and simple operations. It is in.

In order to achieve the above object, the toilet device with a hand wash basin of the present invention performs water supply control by making it possible to perform cooperative water supply to the hand wash bowl in conjunction with the water supply to the toilet bowl, the hand wash bowl, and the wash bowl. In the toilet device with a handwash bowl, the controller includes a registration section that allows registration of a plurality of water supply modes for the handwash bowl , and a selection section for selecting one of the water supply modes registered in the registration section. The control unit is characterized in that the control unit performs the water supply control based on the water supply mode selected by the selection unit when the water supply instruction means instructs the water supply to the toilet bowl. do.

Since the toilet device with a hand wash basin of the present invention has the above-described configuration, it is possible to supply water to the toilet bowl and to the hand wash bowl in a desired water supply mode for each use.

A cleaning position adjustment switch 56 is provided. Note that details of the selection switch 46a will be described later. A user setting switch 60 is also provided. This will also be discussed later.

Among these switch groups, the cleaning strength adjustment switch 55 and the cleaning position adjustment switch 56 are included in the setting switch group. These switches are provided with display lamps 55a and 56a that indicate strength and weakness, front and rear, and each time they are operated, the strength and weakness, front and rear, are cyclically switched, and the display lamps 55a and 56a are also switched accordingly. It should be noted that these are rather set for each individual each time they are used.

In addition, the switch group on the back panel section 36 can be used to set automatic toilet lid opening, power deodorization settings, various temperature settings, butt cleaning width, volume of running water sound, and splash suppression settings. Various switches included in the setting switch group are arranged. As for the butt cleaning width switch 57, it is possible to set it in five stages similarly to the cleaning strength, and an indicator lamp 57a is also provided.

Further, as a group of setting switches on the back panel section 36, a water supply interval switch 61, a hand washing water supply time switch 62, and a hand washing water temperature switch 63 are arranged.

The water supply interval, hand wash water supply time, and hand wash water temperature that can be set with these switches are included in the water supply mode to the hand wash bowl 21 described above. The water supply interval is the time interval between the water supply to the hand washing bowl 21 and the water supply to the toilet bowl 11, and can be set by operating the water supply interval switch 61.

The water supply interval can be set to, for example, 0 seconds (water supply to the toilet bowl 11 and water supply to the hand-washing bowl 21 are almost simultaneous), 3 seconds, 5 seconds, and 10 seconds, and four displays corresponding to these settings are possible. A lamp 61a is also provided. Each time this water supply interval switch 61 is operated, in addition to these four types of time intervals, automatic water supply can be cyclically set with the indicator lamp 61a turned on. Note that the indicator lamps 61a correspond one-to-one to the above-mentioned four types of time intervals, and when automatic water supply is not performed, all of the indicator lamps 61a are turned off.

Further, the hand washing water supply time is the time interval at which water is supplied to the hand washing bowl 21, and three types of cyclic time settings of 5 seconds, 10 seconds, and 20 seconds can be set by operating the hand washing water supply time switch 62. . The set hand washing water supply time is valid both in the case of water supply by operating the hand wash water supply operation section 22 and in the case of water supply in conjunction with the water supply of the toilet bowl 11.

The hand washing water temperature is the temperature of the water supplied to the hand washing bowl 21, and by operating the hand washing water temperature switch 63, three types of cyclic temperature settings can be made: room temperature (no setting), 36° C., and 42° C. The set hand-washing water temperature is valid both when water is supplied by operating the hand-washing water supply operation unit 22 and when water is supplied in conjunction with the water supply from the toilet bowl 11. Further, when the temperature is set at 36° C. or 42° C., the heater section 8 operates.

Note that the number of seconds and number of steps for the water supply interval, the number of seconds and number of steps for the handwashing water supply time, and the temperature and number of steps for the handwashing water temperature that can be set with the above switch regarding the water supply mode to the handwashing bowl 21 are only examples. Needless to say, it may be a numerical value.

At the timing of the operation of the various setting switch groups shown above, preparations are made for operations such as water supply, and setting information is saved in the corresponding setting information storage area. . Note that the means for setting various functions includes not only the operation of each setting switch but also the operation of a combination of a plurality of switches.

Next, the selection section 46 will be explained in detail. In this embodiment, the selection section 46 includes four selection switches 46a. These selection switches 46a can be assigned to each member of the family, for example, to set the mode of water supply to the hand washing bowl 21 and the mode of operation of the private part washing device 15.

Specifically, the above three types of water supply modes can be registered for each selection switch 46a, and furthermore, the operating mode of private part washing can also be registered. In other words, by operating one selection switch 46a, settings can be changed simultaneously for a plurality of water supply modes and operation modes registered and linked to that selection switch 46a, and the settings for the subsequent private washing operation and hand washing water supply can be changed at the same time. Cleaning, water supply, etc. can be carried out in various manners.

The settings for each selection switch 46a can be registered by a combination of the user setting switch 60 on the back panel section 36 and each setting switch. First, when the user selects a desired selection switch 46a, the corresponding display lamp 46b lights up. In this state, each function is set in sequence, and once the desired water supply mode and operation mode have been set, registration is completed by performing a special operation such as pressing and holding the user setting switch 60. When the registration is completed, the display lamp 46b turns off. Setting information for the selection switch 46a is registered in a corresponding area of the registration section 31. Note that the user setting to the selection switch 46a is not limited to the above-mentioned operating procedure, but may be other settings.

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

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

The selection switch 46a (1) (corresponding to item number 1 in FIG. 3) for deep cleaning has water supply interval of 3 seconds, hand washing water supply time of 10 seconds, hand washing water temperature and room temperature, butt washing, and washing strength. The settings are 4 (slightly strong), cleaning width 3 (normal), and cleaning position 4 (slightly forward).

In addition, the selection switch 46a (1) for small washing includes water supply interval: 3 seconds, hand washing water supply time: 5 seconds, hand washing water temperature: room temperature, bidet washing, washing strength: 2 (slightly weak), washing width: 2 (slightly thin) and cleaning position 3 (middle) are set.

The selection switch 46a (2) (corresponding to item number 2 in Fig. 3) for deep cleaning has water supply interval of 5 seconds, hand washing water supply time of 20 seconds, hand washing water temperature of 36°C, butt washing, and washing strength.・2 (slightly weak), cleaning width 2 (slightly thin), and cleaning position 3 (middle) are set.

In addition, the selection switch 46a (2) for small washing has water supply interval of 3 seconds, hand washing water supply time of 5 seconds, hand washing water temperature of 36°C, bidet washing, washing strength of 1 (weak), and washing width of 1. (thin) and cleaning position 2 (slightly behind) are set.

The selection switch 46a (3) (corresponding to item number 3 in Figure 3) for deep cleaning has water supply interval of 0 seconds, hand washing water supply time of 10 seconds, hand washing water temperature of 43°C, butt washing, and washing strength.・2 (slightly weak), cleaning width 5 (thick), and cleaning position 4 (slightly forward) are set.

Furthermore, for the selection switch 46a(3) for small washing, the water supply interval is set to 0 seconds, the water supply time for hand washing is 5 seconds, and the water temperature for hand washing is set to room temperature. No settings have been made for the private part cleaning device 15.

The selection switch 46a (4) (corresponding to item number 4 in Fig. 3) for deep cleaning includes water supply interval - no setting, hand washing water supply time - no setting, butt washing, washing strength - 5 (strong), The cleaning width is set to 4 (slightly thick) and the cleaning position is set to 3 (middle). 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. Moreover, the water supply mode etc. are not set for the small wash of the selection switch 46a(4).

Such settings become effective when any selection switch 46a is operated. In other words, if either of the large/small cleaning switches 41, 42 is operated while any of the selection switches 46a is operated, the water supply will be switched to the corresponding large or small water supply according to the selected selection switch 46a. Among the modes, water supply in the corresponding water supply mode is executed. In the case of private part cleaning, when either the butt/bidet cleaning switch 51 or 52 is operated, the setting is changed to the corresponding private part cleaning operation mode according to the selected selection switch 46a, and the corresponding private part cleaning operation mode is changed. Embodiments of local cleansing are performed.

When any of the selection switches 46a is operated, the display lamps 55a, 56a, 61a, 62a, and 63a corresponding to the setting switch are changed to the corresponding state and are lit, and at the same time, the setting information (water supply mode, etc.) is changed to the specified state. will be rewritten and saved in the settings information storage area. The corresponding setting information storage area is also rewritten as to whether or not the hand washing bowl 21 is linked to the water supply.

Next, the operation of the control unit 30 when an instruction to supply water to the toilet bowl 11 is given will be explained with reference to the flowchart of FIG. The means A for instructing water supply to the toilet bowl 11 includes not only the operation of the cleaning operation section 40 (large flush switch 41, small flush switch 42), but also the timing of leaving the toilet seat 12 (the state of the seating sensor from on to off). change).

When receiving an instruction for either large or small flushing, the control unit 30 controls the flushing 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. The presence or absence of interlocking is determined by referring to the corresponding setting information storage area (S102). If 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 a delay equal to the water supply interval time, the hand-washing control valve 5a is controlled to start water supply to the hand-washing bowl 21, and after a delay equal to the hand-washing water supply time, hand-washing is started. Water supply to the bowl 21 is stopped (S103 to S106). Further, the hand washing water temperature may be set by changing the setting of the heater section 8 at the timing when the selection switch 46a is operated.

As the delay time interval in S103 in FIG. 4, the time interval set in the corresponding setting information storage area as the water supply time is used. That is, when the selection switch 46a is operated and selected, the information in 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. will be adopted.

As the delay time interval in S105 in FIG. 4, the time interval set in the corresponding setting information storage area as the hand washing time is used. In other words, when the selection switch 46a is operated and selected, the information in the registration unit 31 corresponding to the selection is adopted, and when the selection switch 46a is not selected, the time interval set as the water supply interval is adopted. be done.

Note that the water supply interval may be set to a negative value. That is, in the case of a negative setting, when an instruction to supply water to the toilet bowl 11 is given, water is first supplied to the hand washing bowl 21, and after a delay of n seconds, water is supplied to the toilet bowl 11. Needless to say, this operation does not follow the flowchart of FIG. 4, but may follow another operation flow.

Further, the instruction to supply water to the toilet bowl 11 based on the timing of leaving the seat may be determined as large or small by detecting the length of the sitting time, and the water supply may be controlled accordingly. In this case, if the sitting time is longer than the predetermined time, the water supply mode and operation mode will be automatically selected based on the registered information for the large wash, and if the sitting time is less than the predetermined time, the water supply mode and operation mode will be automatically selected based on the registered information for the large wash. The water supply mode and operation mode may be automatically selected based on the registered information.

As described above, since the water supply mode can be determined and registered for each individual in the selection unit 46 of the toilet device 1, the user can operate the selection switch 46a before or during use of the toilet, and then You can wash your hands in a way that suits you by following the toilet bowl cleaning instructions. For example, the user may operate the selection switch 46a when the user is seated or when the user stands up in front of the toilet in the case of men's toilets.

In particular, since the water supply interval can be set variously, water can be supplied at different timings for hand washing for each user. For example, users who want to wash their hands after cleaning the toilet bowl 11 after sitting down and arranging their clothes, users who want to wash their hands after cleaning the toilet bowl 11 and before leaving their seats, and users who want to wash their hands immediately for men's errands. It can be adapted to various aspects such as persons.

In addition, various time intervals can be set for the hand washing water supply time, so it can be set to be convenient for both users who want to wash their hands easily and users who wash their hands thoroughly with soap.

In addition, since the operating mode of the private parts cleaning device 15 can be registered in the registration unit 31 in combination with the water supply mode, settings related to a series of water supply (private cleaning, toilet bowl cleaning, hand washing water supply) can be changed for each user with a single touch. I can do it.

Furthermore, since the two types of registration for large/small cleaning can be assigned to one selection switch 46a, there is no need to provide many selection switches 46a for large/small cleaning, and the operation of the selection switch 46a does not become complicated.

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

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