DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device for performing local cleaning.

[0002]

2. Description of the Related Art A conventional sanitary washing device is provided with a hot water washing device for jetting hot water for local washing, a hot air drying device for jetting hot air for drying, and a toilet seat heating device for warming a toilet seat. There is. Each device is operated by a switch group of an operation unit, and a comfortable cleaning can be performed by a control unit that controls a temperature, an operation time, and the like.

[0003] Among the above devices, the toilet seat heating device controls energization of the heater so as to maintain the temperature of the toilet seat at substantially the body temperature (37 ° C). In a hot water washing device, the set temperature is discharged when hot water is jetted. The energization to the heater of the water heater is controlled so as to be obtained. In some cases, the room is cooled or heated. Therefore, it is necessary to keep the power on all the time, and there is a disadvantage that power is wasted when the unused time period is long, such as at night.

It is also conceivable to turn on the power every time the heater is used to heat it. However, it takes a certain time to heat the washing water in the water heater to a comfortable temperature, so that low-temperature washing water is discharged. There is also a problem that comfortable cleaning cannot be performed.

Therefore, as disclosed in Japanese Patent Publication No. 2-43857, the use time zone and the non-use time zone of the sanitary washing device are set in advance, and the connection of the power supply is automatically switched so that the sanitary washing device is not used. It has been considered that the power consumption is reduced to zero to improve the economic efficiency, and that the cleaning water and the toilet seat are preheated for comfortable cleaning during use.

In the sanitary washing device described in the publication,
An energization start time storage for storing the energization start time and an energization duration storage for storing the energization duration are provided.
The energization of the heating means is controlled based on the information stored in these storages. For example, when the energization start time is set to 6:00 am and the energization continuation time is set to 18 hours, energization is performed from 6:00 am to midnight in accordance with a general household life time.

[0007]

However, in the sanitary washing apparatus described in the above publication, a set of energization start time and energization continuation time can only be set, so that an efficient time according to the lifestyle of the user can be obtained. Could not set.

For example, in the case of a co-earning family, it is useless to turn on electricity at this time because they are not at home during the day.
However, in the above-described conventional sanitary washing device, it is impossible to control the energization time separately.

In view of the above, the present invention makes it possible to set a plurality of energizing times so that the power consumption can be efficiently reduced in accordance with the lifestyle of the user, and to prevent erroneous setting of the time. Aim.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view of a toilet seat device according to the present invention, in which 1 is a toilet bowl having a toilet bowl 1a formed therein, 2 is a flush water tank, 3 is a heated toilet seat, and 4 is a toilet lid. Further, reference numeral 5 denotes a toilet seat device main body, which has a hot water washing device 6 and an indoor heating device 7 therein, and both of these devices 6, 7 and the heating toilet seat 3
A control unit A for controlling the temperature of the water and the end time of the hot water washing is built in, and an operation unit B is provided on the panel unit. Further, reference numeral 8 denotes a washing nozzle which forms a part of the hot water washing device and is capable of moving back and forth in the direction of the toilet bowl 1a, and 9 denotes a hot air outlet provided near the nozzle 8.

FIG. 2 is a block diagram showing a control system by the control unit A and the operation unit B. First, the hot water cleaning system will be described. The cleaning nozzle 8 communicates with a hot water tank 12 having a built-in heater 10 and a temperature sensor 11, and the hot water tank 12 has a solenoid valve 13 in the middle to supply water such as tap water. Communicating. 1
Reference numeral 4 denotes a water amount controller provided between the hot water tank 12 and the washing nozzle 8. S-5 is a hot water switch for switching the presence or absence of energization of the heater 10. The control unit A controls the temperature of the washing water via the temperature sensor 11 and the heater 10. The setting of the hot water temperature is based on the hot water temperature of the operation unit B. This is performed by the setting volume C-1. The cleaning nozzle 8 is advanced and retracted in the axial direction by the motor 15, and moves forward to reach the bidet cleaning position by operating the cleaning switch S-1 and operating the bidet cleaning switch S-2. The detection of the cleaning position and the storage position of the cleaning nozzle 8 is performed by the position sensor 16.

Next, the indoor heating system will be described. The indoor heating device 7 includes a blower fan 19, a heater 20 provided in the flow path, and an indoor temperature sensor 21, and the power supply to the blower fan 19 and the heater 20 is controlled by the indoor heating system. The setting of the heating temperature is performed by the switch S-3 and the heating temperature setting volume C-
Perform by 2.

A heater 17 for heating and a temperature sensor 18 are mounted on the toilet seat 3, and the temperature of the toilet seat is controlled by both of them and the control unit A. The switching of the power supply to the heater 17 is performed by a toilet seat switch S-6. The temperature is set by the toilet seat temperature setting volume C-3.

S-4 is a stop switch for stopping the operation of each device, and S-7 is a water pressure adjusting knob for controlling the cleaning water force from the cleaning nozzle 8.

Next, the means for setting the operable time of each device described above will be described.

M-1 is an energization time setting means provided in the operation section B, and sets a plurality of sets of an operation start time and an operation end time at which a washing process including hot water washing, toilet seat heating, and indoor heating becomes operable. A set can be set.

As shown in FIG. 3, the user can set a plurality of operation start times (first times) and corresponding operation end times (second times) in the energizable time setting means M-1. A time setting switch M-11 for inputting, a holding circuit M-12 for temporarily holding each input time, and a time set based on the relationship between the times held in the holding circuit M-12 A set time discrimination circuit M-13 for discriminating inappropriateness is provided. Set time discrimination circuit M-1
At 3, when each time is input, it is determined whether each operation time determined by each operation start time and the corresponding operation end time, that is, each time zone overlaps. Since the set time is considered to be inappropriate, the setting of the operation time by the energizable time setting means M-1 is disabled. That is, the contents of the holding circuit M-12 are not stored in the storages M-2 and M-3 shown in FIG.

The set time discrimination circuit M-13 includes a display M
-5 is connected, and when the set time discrimination circuit M-13 determines that the set time is inappropriate, a display indicating that the set time is inappropriate is displayed on the display device M-5. . Although a dedicated display device may be used as the display device M-5, it is desirable that the display device also serves as another display device, for example, a time display unit of a clock.

M-2 and M-3 are operation start time storages for storing a plurality of operation start times according to operation signals of the energizable time setting means M-1, and a plurality of operation start times corresponding to the plurality of operation start times. It is an operation end time storage for storing an operation end time.

M-4 receives the output signals from both storage devices M-2 and M-3, and when the output signal is an operation time signal, outputs an output signal for activating the control unit A to the non-operation time. When the signal is a signal, it is an operation determining means for generating an output signal for inactivating the control unit A. That is, the operation determining means M-4
Compares the operation time between each operation start time and the corresponding operation end time with the current time indicated by the clock circuit M-6. When the current time becomes the operation start time, the operation time , And when the current time reaches the operation end time, the output of the non-operation time signal is started.

Therefore, the control unit A can output or stop the output by the signal from the operation determining means M-4. Can be set.

For example, in the case of a family with double income, the first operation start time is 6:00 am, the first operation end time is 9:00 am, the second operation start time is 4:00 pm, and the second operation end time is 4:00 pm. Is 11 o'clock in the afternoon, a total of 10 hours, that is, 3 hours in the morning and 7 hours from the evening to the night, can be set as the washable time zone. In this operation time zone, a signal can be output from the control unit A, so that the warm water and the toilet seat 3 are controlled to keep the temperature at a predetermined temperature, so that ordinary comfortable washing can be performed. In addition, from 9:00 am to 4:00 pm when the user is not at home, there is a low possibility that the user will be used at 11 pm
In the non-operating time of 14 hours from time to 6:00 am,
Since there is no output signal from the control unit A and all power supply is stopped, power consumption when not in use can be efficiently prevented in accordance with the lifestyle of the user.

It is to be noted that the power consumption may be reduced by making the amount of energization smaller than that in the operation time zone, instead of stopping all energization in the non-operation time zone.

FIG. 4 is a flowchart showing the above timer operation. When the current time reaches the operation start time (step 101), the power of the heating means is turned on (step 102), and when the current time reaches the operation end time (step 103), the power of the heating means is turned off (step 104). .

Next, a specific example of an apparatus and a control circuit for setting the above-mentioned possible cleaning operation time will be described with reference to FIGS. In FIGS. 5 and 6,
The illustration of various switches S1 to S7 shown in FIG. 1 for the user to directly operate the toilet seat device is omitted.

FIG. 5 shows an operation / display device 30 for setting and displaying time. The operation / display device 30 corresponds to the energizable time setting means M-1 and the display device M-5 shown in FIG. The operation / display device 30 includes:
An operation switch unit 31 and a display unit 32 are provided. The operation switch unit 31 includes a changeover switch 31a for switching the operation mode of the timer, an hour switch 31b for setting "hour", a minute switch 31c for setting "minute", and a timer switch for enabling the timer operation. , And a release switch 31e for disabling the timer operation. The display unit 32 includes a time display unit 32a for displaying the current time and the set time, and a mode display unit 32b for displaying the operation mode of the timer.

The signals from the switches 31a to 31e are
As shown in FIG. 6, a clock circuit 33 (FIG.
(Corresponding to the clock circuit M-6 of FIG. 3) and the microcomputer 35 via the input interface 34. The microcomputer 35 is connected to a ROM (read only memory) 36 in which a timer control program and the like are written, and a RAM (random access memory) 37 for storing a plurality of sets of operation start times and operation end times. I have. The RAM 37 stores an energization start time memory M-2 and an energization end time memory M shown in FIG.
-3. Further, the microcomputer 35
Is connected to the display unit 32, the hot water washing control circuit 39, the heating toilet seat control circuit 40, and the indoor heating control circuit 41 via the output interface 38. Hot water washing control circuit 39,
The heating toilet seat control circuit 40 and the indoor heating control circuit 41 control the operations of the hot water washing device 6, the heating toilet seat 3, and the indoor heating device 7 shown in FIG. The above microcomputer 3
5 corresponds to the determination means M-4 and the control unit A shown in FIG.

Next, the operation of the circuit shown in FIG. 6 will be described.

In the embodiment shown in FIG. 6, the timer has a plurality of operation modes, and each time the changeover switch 31a is pressed, the "current time adjustment" mode, the "timer 1 on time" mode, and the "timer 1 off". The mode of the “time” mode, the “timer 2 on time” mode, and the “timer 2 off time” mode are sequentially switched. The current mode is
In the mode display section 32b, it is possible to know by sequentially displaying the characters "time adjustment", "on time 1", "off time 1", "on time 2", and "off time 2".

In each mode, as shown in the flowchart of FIG. 7, every time the hour switch 31b is pressed (step 201), the time is advanced by one hour (step 202).
Each time the minute switch 31c is pressed (step 203), the time advances by one minute (step 204). Switch 31a
Is turned on (step 205), the microcomputer 35 determines whether there is no overlap in the operation time determined from the set time (step 206). If there is no overlap, the set time is stored in the RAM as it is.
37 is stored in a predetermined area (step 207). For example, the time set in the “timer 1 on time” mode is stored in the “timer 1 on time” area of the RAM 37. The same applies to other modes.

For example, a “timer 1 on time” mode,
Assume that 6:00 am, 9:00 am, 4:00 pm, and 11:00 pm are set in the “timer 1 off time” mode, “timer 2 on time” mode, and “timer 2 off time” mode, respectively. In each setting, the time display section 32a displays “AM 6:00”, “AM 9:00”, “PM
4:00 ”and“ PM 11:00 ”are sequentially displayed, and time data corresponding to these times is stored in the RAM 3.
7 are sequentially stored in corresponding areas.

If it is found that the operation times overlap when the changeover switch 31a is turned on, the set time is regarded as inappropriate and the data is not stored in the RAM 37. In addition, the display time is blinked at a predetermined cycle on the time display section 32a to notify the user that the setting is impossible (step 208).

For example, “timer 1 on time”, “timer 1 off time”, “timer 2 on time”, and “timer 2 off time” are 7:00 am, 9:00 am, 8:00 am, 1 am
When trying to set 1 o'clock, it is known that the operation time overlaps when 8:00 am is input as the "timer 2 on time". At this time, the time input to call the user's attention is changed to The display is blinked for a predetermined time, for example, 3 seconds, and then the display is blanked to wait for re-input.

Further, in each mode, the switch 31b or the minute switch 31 for a predetermined time (for example, 15 seconds).
When c is not operated, the mode automatically returns to the clock display mode, and the current time is displayed on the time display section 32a.

When the reservation switch 31d is pressed and the timer operation is enabled, the current time indicated by the clock circuit 33 is used to store the "timer 1 on time" and "timer 1 off time" stored in the RAM 37. , Or the time between “timer 2 on time” and “timer 2 off time”, that is, whether or not it is the operation time. If it is the operation time, the hot water cleaning control circuit 39,
The hot water cleaning device 6, the heating toilet seat 3, and the indoor heating device 7 can be operated via the heating toilet seat control circuit 40 and the indoor heating control circuit 41.

In the above-described embodiment, when the time is improperly set, the user is visually alerted by the display device. , An electronic buzzer, a synthesized voice, or the like.

In the above-described embodiment, the operation time is defined by the set of the operation start time and the operation end time. However, the operation time is defined by the set of the operation start time (first time) and the operation continuation time. It may be specified. In this case, FIG.
May be provided with an energization duration storage unit instead of the energization end time storage unit M-3, and the energization duration time may be set from the energization time setting unit M-1. However, the timer operation in this case is an operation as shown in the flowchart of FIG.
That is, when the current time reaches the operation start time (step 301), the power of the heating means is turned on (step 30).
2) If the current time is during the operation continuation time, this state is continued (step 303), and when the operation continuation time ends, the power supply of the heating means is turned off (step 30).
4).

Further, in the above-described embodiment, the operation section is provided on the toilet seat apparatus main body side. However, the remote operation control section having the operation section and the display section is located at an easily operable position away from the toilet seat apparatus main body. And the toilet seat device main body may be controlled by remote control using infrared rays or the like.

Further, a seat detecting means M-7 is provided on the toilet seat, and when the seat detecting means M-7 detects the seating of the user, the seat is detected even during a non-operating time zone. During this time, the operation determining unit M-4 may be configured to supply power to each heating unit.
