FIG. 1 is a timing chart showing an operation sequence of a function for controlling a toilet environment of a sanitary washing device. In accordance with the order set by the user, the toilet seat heater is turned on to perform a toilet seat temperature control operation to control until the temperature reaches a predetermined set temperature. When the control of the toilet seat heater is completed, the control of the hot water heater starts up and performs the hot water control. Then, control is performed until a predetermined set temperature is reached. Hereinafter, the operation of the indoor heating heater is similarly performed.

As an example, when the function for controlling the toilet environment is started, the time until the target value is reached is estimated. When the boiling time is calculated using a standard hot-water storage toilet seat (1000 ml tank, 600 W heater, heater thermal efficiency 95%, washing temperature 40 ° C.), the washing water 100
Assuming that 0 ml is boiled, the current water temperature of the tank is estimated to be 15 ° C., and the necessary heat capacity (joules) = 100.
0 × (40−15) × 4.19 = 104750 (joules) When this is boiled with a heater of 600 W and a heater thermal efficiency of 95%, required time (second) = 125700 ÷ 600 ÷ 0.95 = 1
84 (seconds) Hot water will boil in about 3 minutes and 3 seconds. Next, the heating toilet seat is determined by the heat capacity of the toilet seat, the outside air temperature, etc. According to the actual measurement graph, the standard heating toilet seat (60 W heater, ambient temperature 15 ° C.) is used until the toilet seat surface temperature of the toilet seat temperature adjustment volume MAX reaches 40 ° C. It takes about 7 minutes to reach the target temperature. (Refer to FIG. 3 for details.) Also, in the case of indoor heating, the size of the room, the heat insulation, etc. are affected, but a standard size toilet booth (W: 1.7 × D: 0.8 × H: 2) (unit: meter) is as follows. Room heating (400W heater, ambient temperature 15 ° C) is room heating adjustment volume MAX
It takes about 50 minutes to raise the room temperature by 10 ℃. (See FIG. 4 for details.) As described above, in the sanitary washing device having the function of controlling the toilet environment, it takes time to bring the temperature to the set temperature. If the priority function is determined and used, it can be used without increasing current consumption.

Usually, it is considered that the function of controlling the toilet environment is operated by a timer operation in order to save power, but all functions are originally provided in the environment (the toilet room, the toilet seat, the toilet seat, etc.).
It is well known that it takes time to make washing water) comfortable, temperature, humidity and odorless. For example, if the first function is the hot water, the second is the toilet seat, and the third is the indoor heating, the priority operation setting means sets the functions in that order. The toilet environment detecting means is various sensors such as a hot water thermistor and a toilet seat thermistor. The microcomputer registers the toilet seat shown in FIGS. 3 and 4 and the relationship between the temperature and time in the room with the table value in the memory of the microcomputer. The required time can be easily estimated for the current temperature and the target temperature. When the user sets a timer operation as a use time zone from 6:00 in the morning, the microcomputer monitors the indoor temperature and the water temperature. At the time of use start time 6:00, the function to control the toilet environment is calculated from the temperature so as to be the set temperature, and at a certain point, the microcomputer performs a calculation when it takes 7 minutes for toilet seat, 3 minutes for washing water, and 50 minutes for indoor heating, When the sum of the current time and the required time exceeds the use start time, the operation is performed according to the priority operation order. By doing so, the function of controlling the toilet environment at the use start time 6:00 is set to the set temperature.

Further, the current consumption is suppressed by focusing on the current consumption.
The following method is used to suppress the display of the power consumption of the device. Since the heater capacity is 60 W for toilet seat, 600 W for washing water, and 400 W for indoor heating, the maximum power consumption is the maximum power consumption when the washing water heater heats hot water. Therefore, if the maximum power consumption is limited to this 600 W and the other load is prevented from entering at the same time, the maximum power consumption is 600 W
Can be displayed. And within the range not exceeding 600W
The toilet seat heater and the indoor heating can be simultaneously energized. (A total of 460 W and less than 600 W is required.) By doing so, the required time can be reduced.

FIG. 2 is a timing chart showing the operation sequence of a plurality of functions of the sanitary washing device and the human body detection signal. If the human body detection signal is detected to be ON during the priority operation, for example, if the indoor heating heater is operating, the operation is interrupted.
When the OFF of the human body detection signal is detected, the indoor heating operation is performed again. Hereinafter, the same applies to the operations of the toilet seat heater and the washing water heater, and the priority operation is interrupted when the human body detection signal is turned on, and normal control (priority operation is not performed) is performed.

FIG. 3 is a graph of the toilet seat surface temperature and the energizing time of the sanitary washing device. AC100V, 50 as conditions
This is an example when / 60 Hz is applied, the indoor temperature condition is 15 ° C., and the toilet seat temperature adjustment volume is at the MAX position. In this way, the temperature reaches the set temperature within several minutes to 10 minutes, although there is a difference depending on the model.

FIG. 4 is a graph of the indoor heating temperature adjustment characteristic of the sanitary washing device. The relationship between the room temperature and the energizing time is shown. There are two conditions of AC100V, 50 / 60Hz, and the outside air temperature in the room is 5 ° C and 15 ° C. This is an example of a general model. It takes until it reaches the temperature.

FIG. 5 shows measurement points and room dimensions of the indoor heating temperature of the sanitary washing device. The dimensional unit is expressed in mm. The temperature near the feet in the toilet space where such aiming is not possible is measured.

FIG. 6 shows a hot water (wash water) temperature adjustment volume 86, a toilet seat temperature adjustment volume 87, and a room warm temperature adjustment volume 89, which indicate an operation section and a display panel. Display LED
12, an indoor heating priority display LED 13 is provided to indicate the order in which the priority operation is set. Here, for each function, for example, the colors green, yellow, and red correspond to 1, 2, and 3, respectively, in an order in which each volume is turned clockwise from a turned-off state (a state turned completely to the left) to a set state. The priority operation order is displayed for all the operated functions. When canceling, for example, when the toilet seat temperature adjustment volume, which is set second in priority, is turned off, the room warming function set to priority 3 rises to priority 2 and the display changes from red to yellow. . This is just
Since the priority order is set, the priority order becomes important only when a normal operation starts, for example, when the temperature of the thermistor is reduced to a control start state.

FIG. 7 is a block diagram showing the internal configuration of the microcomputer peripheral circuit 90 incorporated in the sanitary washing device and its peripheral devices. The microcomputer peripheral circuit 90 includes a CPU 91 for executing various arithmetic processes for controlling the temperature of the washing water and the like according to a preset control program, and a control program and control data necessary for the CPU 91 to execute various arithmetic processes.

And an output processing circuit 96 that outputs a signal to a solenoid valve, a heater for washing water, or the like in accordance with the result of calculation by the CPU 91. I have. The backup memory 9
Reference numeral 4 denotes a backup device that is backed up by a built-in battery, an electrically readable / writable backup device such as a flash memory, and various devices whose data is not erased even when the power is turned off can be applied.

The hot water tank is provided with a hot water thermistor 51 and a float switch 62. These various sensors and switches are electrically connected to the input processing circuit 95 of the microcomputer peripheral circuit 90, and various actuators (water stop electromagnetic valves 71, Hot water heater 76,
The process of adjusting the nozzle position by the flow regulating motor 73 and the nozzle drive motor 74), the process of performing cleaning, and the like are executed. The rough operation of the sanitary washing device based on the processing executed by the CPU 91 of the microcomputer peripheral circuit 90 is as follows. When the user sits on the toilet seat, a signal to that effect is output from the seating sensor. Thereafter, when the user operates the operation switch, for example, when the buttocks washing SW 81 is pressed, the nozzle driving motor 74 is driven to drive the nozzle. Are integrally extended to the washing position, the water stop electromagnetic valve 71 is opened, and the flow control switching valve 72 is connected to the buttocks washing flow path to start jetting of washing water from the nozzle head of the nozzle. Then, when the user presses the stop switch 84 on the operation panel after the washing is completed, the water shutoff electromagnetic valve 71 is closed and the flow control switching valve 72 is connected to the neutral position to terminate the ejection of the washing water, and thereafter, the nozzle drive is performed. The motor 74 is reversed to retract the nozzle to the storage position. Similarly, when the bidet cleaning SW 82 is pressed, the nozzle advances to the bidet cleaning position, communicates with the bidet cleaning flow path by the flow control switching valve 72, starts jetting of cleaning water from the nozzle head, and presses the stop SW 84. This completes the cleaning.

In the toilet seat temperature control, the toilet seat temperature is detected by the toilet seat thermistor 52 in accordance with the set value of the toilet seat temperature adjustment volume 87, and the toilet seat heater 77 is controlled. Therefore, the toilet seat surface is maintained at an appropriate temperature by the toilet seat heater 77 inside the toilet seat surface.

The drying operation is performed by a drying temperature adjusting volume 8.
In accordance with the set value of 8, the drying thermistor 53 detects the drying temperature sent by the drying motor 75 and controls the drying heater 78 to keep the drying temperature at an appropriate temperature.

Similarly, in the room heating operation, the room heating heater 41 is energized in accordance with the set value of the room temperature adjusting volume 89, and the room heating motor 42 emits warm air. Here, the room temperature is detected by the room temperature thermistor 31, and the hot air is continuously output until the room temperature is reached. When the room temperature decreases, the room temperature thermistor 31 detects the temperature and emits warm air to keep the room temperature.

[0027]

According to the present invention, when a plurality of electric appliances are installed, the toilet environment is maintained while keeping the power consumption within a predetermined range without simultaneously operating the function of controlling the toilet environment. Since the function of controlling the toilet environment can be simultaneously operated to prevent the current consumption from temporarily increasing, no new wiring work or the like is required to increase the current capacity of the indoor wiring.
