SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a toilet apparatus provided with a timer means for setting a heating operation time, comprising a use detecting means for detecting use of a toilet and the timer means. Is characterized in that when a use detection output is given from the use detection means during the heating operation time, the heating stop time which has been already set is extended.

The timer means can set a heating start time, and during the timer operation from the heating start time set by the timer means to the heating stop time,
The heating stop time may not be extended by the use detection output.

[0007]

When the use detecting means detects the use of the toilet, the timer means extends the already set heating stop time. Therefore, the heating operation does not stop during use of the toilet.

[0008] Further, when the timer means can set a time zone from the start to the stop of the heating, the heating operation time is not extended by the use detection during the timer operation, so that the set heating time can be reduced. The timer operation is not extended unnecessarily. Therefore, it is possible to prevent the heating from operating during an undesired time period.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 3 is an external perspective view of the toilet device according to the present invention. The toilet apparatus 1 includes a toilet body 2 and a
And a toilet seat 3 having a function such as heating. The toilet seat 3 includes a toilet seat body 3a, a toilet lid 3b, and a sleeve 3c. The rear part of the toilet seat 3 houses a heater 4 for supplying hot water for washing, including a nozzle 4 for washing the buttocks and bidet, a use detecting means 5, a heater and a fan for drying the buttocks, a controller, a power supply, and the like. Is done. The toilet body 3a has a built-in heating element 6 for heating the toilet seat.

The upper surface of the sleeve 3c is an operation / display section 7, on which various operation switches, operation knobs, and status display lamps are arranged. FIG. 4 shows a specific example of the operation / display unit 7. FIG. 5 is a sectional view of the sleeve taken along line AA. The room heating means 8 is accommodated inside the sleeve 3c. The indoor heating means 8
Fan motor 8a and heater 8b provided downstream thereof
In the indoor heating operation state in which the fan motor 8a is driven and the heater 8b is energized, warm air is blown obliquely from the outlet 8c toward the floor.

FIG. 1 is a functional block diagram showing the control of the indoor heating of the toilet apparatus. The timer means 10 comprises a clock means 11 for measuring time, an operation time setting means 12, a heating operation control means 13, an on time storage means 14 and an off time storage means 15.

When the timer operation ON / OFF switch 21 is operated in a state where the timer operation is not set (a state in which the heating timer operation indicator 23 is turned off), the operation time setting unit 12 operates the clock unit 11. The start time of the timer operation is calculated by adding the time set by the on-time setting unit 22 to the current time data 11a supplied from the server, and the calculated operation start time is written into the on-time storage means 14. The on-time setting unit 22 is configured using a variable resistor or the like, and has a scale every hour. The entry time setting unit 22 is configured to perform setting at least in units of 15 minutes.

For example, when 10 hours later is set in the entry time setting section 22 and the timer operation on / off switch 21 is operated at 8:00 pm, the operation time setting means 12 sets the data of the operation start time 6:00 am to the input time. Write to the storage means 14. Also,
The operation time setting means 12 outputs a timer operation command 12a to notify the heating operation control means 13 of the timer operation state, and turns on the heating timer operation indicator 23 to set the timer operation to the user. Is displayed.

If the timer operation on / off switch 21 is operated while the heating timer operation indicator 23 is lit, the operation time setting means 12 determines that the timer operation has been cancelled, and The output of the operation command 12a is stopped, and the heating timer operation display is turned off.

Upon receipt of the timer operation command 12a, the heating operation control means 13 compares the operation start time data 14a stored in the on-time storage means 14 with the time data 12a from the clock means 11 and operates. At the time, a heating operation command 13a is output. Also, the heating operation control means 13
Calculates the operation end time by adding a preset operation time, for example, 6 hours, to the operation start time, and stores the data 14b related to the calculated operation end time in the cutoff time storage unit 15
Write to Based on the output of the heating operation command 13a, the indoor heating means 8 is activated, and the indoor heating operation indicator 24 is turned on to visually indicate that the indoor heating operation is in progress.

After outputting the heating operation command 13a, the heating operation control means 13 compares the operation end time with the current time, and stops outputting the heating operation command 13a when the operation end time is reached. Therefore, when the timer operation is set, the heating operation is automatically performed at the same time every day as shown in FIG.

The heating operation control means 13 can also start or start the heating operation by operating the indoor heating on / off switch 25.
It is configured to stop. When the heating operation command 13a is not output, the indoor heating on / off switch 25
Is operated, the heating operation control means 13 outputs the heating operation command 13a to operate the room heating means 8 and turns on the room heating operation indicator 24. The heating operation control means 13 adds a preset heating operation time, for example, 6 hours, to the time when the indoor heating on / off switch 25 is operated, and outputs the added value as operation end time data as off time storage means. Write to 15. Then, when the operation end time comes, the output of the heating operation command 13a is stopped,
The heating operation and the heating operation display are stopped. The above operation is shown in FIG.

In the state where the timer operation is set and before the time when the timer operation is started, the indoor heating ON / OFF switch 25 is operated to start the heating operation. When the start time of the timer operation comes, the heating operation control means 13 is configured to continuously output the heating operation command 13a until the end time of the timer operation is reached. Therefore, the room heating operation is continued until the end time of the timer operation, as shown in FIG.

When the indoor heating ON / OFF switch 25 is operated in a state where the heating operation command 13a is output, that is, in the heating operation state, the heating operation control means 13 stops the output of the heating operation command 13a. Then, the heating operation is stopped.

If the indoor heating on / off switch 25 is operated during the heating operation by the timer, the heating operation is also stopped. However, when the indoor heating on / off switch 25 is operated again during the heating operation time period by the timer, the heating operation control means 13 starts the heating operation from the operation time again, and operates for, for example, 6 hours from the operation time again. The heating operation is stopped at the time. FIG. 2D shows the manual turning on / off operation during the timer operation.

The heating operation control means 13 outputs a heating operation command 1
When the detection output 26a for detecting the use of the toilet apparatus 1 or the toilet in which the toilet apparatus 1 is installed is given from the use detection means 26 in a state where 3a is output, that is, in the heating operation state, FIG. e) As shown in
The configuration is such that time data after a preset operation extension time (for example, 6 hours) from that time is calculated and written to the off time storage means 15 to change the operation end time.
The extension of the operation end time is performed in both the manual heating operation and the timer operation. Therefore, the operation end time is initially set during use of the toilet, and the indoor heating operation is not stopped.

However, extending the heating operation time during the timer operation means that the heating operation is continued until a time period that the user does not want, and power is consumed unnecessarily for heating. Therefore, control can be performed so that the operation end time is not extended even if the detection output 26a from the use detection means 26 is given during the timer operation (FIG. 2 (f)).

The use detection output 26 is used to prevent the heating operation time from being unnecessarily prolonged due to erroneous detection or the like.
The configuration may be such that the operating time is extended when a continues for a predetermined monitoring time. In this case, the heating operation control means 13 is configured to output the heating operation command 13a while the use detection output 26a is given so that the heating operation is not stopped during the monitoring time. Also, the heating operation is continued while the use detection output 26a is given, and when the use detection output 26a stops, that is, when the use of the toilet ends, the operation time is extended. Is also good. During use of the toilet, not only the indoor heating is continued but also the heating operation is extended for a predetermined time, so that the heating operation state can be secured for the next toilet user after a short time.

The use detecting means 26 uses a seating detection system for detecting seating on the toilet seat. In addition, by detecting infrared rays emitted from the human body with, for example, a pyroelectric sensor,
It is good also as composition which detects use of a restroom including small use of a boy.

The room heating means 8 includes a room temperature control means 27. The room temperature control means 27 is activated when the heating operation command 13a is supplied, and outputs a room temperature detection output 28a of a room temperature detection means 28 such as a thermistor provided upstream of the fan motor 8a, and a room heating temperature setting means 29. By controlling the energization of the fan motor 8a and the heater 8b by comparing with the indoor heating temperature 29a set in the above, the toilet indoor temperature is controlled to be substantially the set temperature.

With the above configuration, when the use of the toilet is detected during the indoor heating operation, the toilet apparatus 1 according to the present invention extends the heating operation for a preset extension time from the detection point. Therefore, the operation is not stopped during the use of the toilet and the heating is not stopped. Also,
Since the heating operation is extended for a predetermined time, the heating operation state can be secured for the next toilet user after a short time.

The timer means 10 is used not only for the heating operation but also for the control of the power supply time period of the heating toilet seat and the control of the power supply time period of the heater for heating and keeping the washing water warm. be able to.

In this embodiment, the cutoff time storage means 15
The timer means 10 for stopping the operation at the operation end time written in the above has been described.
When the use detection output 26a is given, the operation time may be extended by resetting or presetting the counter value.

The operation time may be extended by, for example, one hour only when the usage detection output 26a is given when the remaining time of the heating operation is a predetermined time such as 30 minutes.

[0030]

As described above, the toilet apparatus according to the present invention is configured to extend the heating stop time set by the timer means when the use of the toilet is detected, so that the heating is stopped during use of the toilet. Never. In addition, since the heating operation is extended for a predetermined time, the heating operation state can be secured for the next toilet user after a short time.

In addition, since the heating operation time is not extended by the use detection during the timer operation, the heating operation time zone set for the heating operation is not extended unnecessarily. For this reason, it is possible to prevent heating from operating during an undesired time period.
