DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling an electric device, and more particularly to a method for dealing with an abnormality in at least a part of an electric device having a plurality of energized parts. The present invention relates to a control method of an electric appliance suitable for application to household electric appliances such as a hot water washing device for washing a buttocks of a toilet user with hot water, for example.

[0002]

2. Description of the Related Art In a hot water washing apparatus, hot water from a hot water source such as a hot water tank is supplied to a washing nozzle, and the washing water is jetted upward or diagonally upward from the tip of the washing nozzle to wash the buttocks of a human body. Have been. In recent years, a hot water washing apparatus provided with a hot air drying mechanism for blowing hot air to the buttocks after washing to dry the hips has been widely used. The toilet seat of a Western-style toilet provided with this hot water washing device is usually a heating toilet seat having a heater. Japanese Unexamined Patent Application Publication No. 5-295783 discloses that when a failure occurs in such a device, a function of prompting repair by displaying a failed portion by a light emitting element is described.

[0003]

In the case of a hot water washing device with a heated toilet seat, 100 V is applied to the heater of the heating toilet seat, the heater of the hot water tank of the hot water washing device, or the heater of the hot air fan for drying the buttocks. . Even if one of the heaters is disconnected, the remaining heaters can be energized. Therefore, the user uses a hot water washing device with a heated toilet seat without asking for repairs and without any inconvenience. Often continue to do so. If the failure location is left as described above, the failure is likely to increase.

[0004] It is an object of the present invention to prevent an electric device from being forcibly continued to be used as it is when an abnormality such as a failure occurs in a part of the energized portion.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a method for controlling an electric device having a plurality of energized parts, the method comprising the steps of: It is characterized in that energization of the energized part is stopped.

According to such a control method of an electric device, even if an abnormality occurs only in a part of the energized portion, the electric device stops the energization of at least one or all of the energized portions, so that the abnormal state of the electric device occurs. It is prevented from being used further while being held.

It is preferable that the energized portion is a portion to which a voltage of 100 V or more is applied.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a hot water washing device with a heated toilet seat as an electric device according to an embodiment, and FIG. 2 is a flowchart showing control contents of the hot water washing device.

In FIG. 1, water such as tap water flows into a hot water tank 3 via a water supply pipe 1 and a main valve 2. The hot water tank 3 is provided with a heater 4 and a thermistor 5 for detecting temperature, and the water is heated at a predetermined temperature (hot water).
It is said. This hot water is sent to a washing nozzle 9 via a pipe 6, a flow sensor 7, and a flow rate (washing strength) adjusting valve 8.
It is jetted upward or obliquely upward from the tip of the nozzle 9 and poured onto the buttocks of the occupant of the heating toilet seat 10. Although not shown, a pump for supplying hot water to the nozzle 9 may be provided.

The heating toilet seat 10 has a toilet seat body 12 supported by a toilet seat box 11 so as to be freely rotatable in the vertical direction, and a heater 13 provided on the toilet seat body 12. The main valve 2, the hot water tank 3, the flow sensor 7, and the washing nozzle 8 are installed in the toilet seat box 11.

A warm air fan 20 and a controller 30 for blowing hot air onto the buttocks of the seated person are installed in the toilet seat box 11. The hot air fan 20 includes a blower 21 and an air heater 22. The thermistor 24 is installed in the toilet seat box 11 near the circuit board in order to measure the temperature of the circuit board (not shown) of the controller 30.

The controller 30 transmits and receives signals to and from a controller 40 such as a remote controller, and also controls the thermistors 5 and 2.
4 and a thermistor (not shown) provided on the toilet seat body 12
Receives a temperature signal.

The controller 40 includes a liquid crystal display panel 41
Besides, a washing switch 42, a hot air switch 43, a stop switch 44, a heating toilet seat switch 45, a temperature switch 4 for adjusting the temperature of hot water, hot air or a heating toilet seat.
6. It has a speaker 47 for generating sound.

When the washing switch 42 is pressed, the main valve 2 is opened, hot water is spouted from the washing nozzle 9, and when the stop switch 44 is pressed, the main valve 2 closes and the hot water stops.

When the hot air switch 43 is pressed, the hot air fan 2
When the warm air blows from 0 and the stop switch 44 is pressed, the warm air stops. When the heating toilet seat switch 45 is pressed, the heater 13 of the heating toilet seat 10 is energized to heat the toilet seat, and when the heating toilet seat switch 45 is pressed again, the energization to the heater 13 is stopped.

The temperature of the heating toilet seat 10 is adjusted by operating the temperature switch 46 in a state where the heating toilet seat switch 45 is turned on and neither the buttocks washing nor the hot-air drying is performed, and in a state where hot water is jetted out. By operating the temperature switch 46, the temperature of the hot water is adjusted. By operating the temperature switch 46 while the hot air is being blown out, the temperature of the hot air is adjusted.

The temperature and operating state of the hot water, hot air, and heating toilet seat are displayed on the liquid crystal panel 41 together with the date and time.
The controller 30 may use a battery as a power source or a commercial power source as a power source.

A 100 V AC voltage from a commercial power supply is applied to the heaters 4, 13 and 22.

In this hot water washing apparatus with a heated toilet seat, when an abnormality such as disconnection occurs in any of the heaters 4, 13, and 22, the power supply to all the remaining heaters is stopped.

As a result, the heating toilet seat 10 remains cold, only cold water flows out from the washing nozzle 9 and only normal-temperature air is blown out from the hot-air fan 20. , Repair shops, manufacturers, etc., to prevent the abnormality from expanding.

If an abnormality occurs in the heater, the fact is displayed on the liquid crystal display panel 41,
Control such as utterance from 7 or blinking of some or all of the display lamps may be executed.

In the present invention, when an abnormality occurs in at least a part of the heater or the like, the power supply to all the power supply parts including the heater may be stopped.

In the present invention, when an abnormality occurs not only in the heater but also in the thermistor and various sensors, the control may be performed so as to stop energizing all the heaters and other energized parts.

Although the above embodiment relates to a hot water washing apparatus with a heated toilet seat, the present invention can be applied to control of various other electric appliances.

[0026]

As described above, according to the present invention, even when an abnormality occurs only in a part of the electric equipment, the user can receive the maintenance, and the expansion of the failure can be prevented.
