In this apparatus, means for detecting the temperature of the toilet seat is arranged for controlling the temperature of the heater, and this temperature information must be sent to a control circuit on the toilet body side. Further, many toilets of this type, particularly those having a local cleaning device, are provided with a seating detection switch for detecting seating on the toilet seat. In this case, the seating information detected by the seating detection switch is also controlled by the above-mentioned control. Must be sent to the circuit.

Since the toilet seat is rotatably mounted on the toilet, it is necessary to take this point into consideration, and from the sanitary point of view, the toilet seat can be removed from the toilet body so that it can be washed. If you want to be able to remove it, you have to take this into account. For this reason, conventionally, the rotation of the toilet seat has been ensured by using a cord and a waterproof connector that are drawn out between the control circuit on the toilet body side and the toilet seat to the outside, and the toilet seat has been removed easily. .

[0004]

However, it is difficult to reduce the stress applied to the cord when the toilet seat is rotated. For example, if the cord is connected in a twisted state, the cord may be disconnected due to the stress. There is. Although the waterproof connector is adopted, the connection terminal is exposed when the connector is disconnected, and water will adhere to the connection terminal if the toilet seat is washed or the toilet body is wiped with water. As a result, the connection terminal may be corroded.

The present invention has been made in view of such a point, and an object of the present invention is to prevent the information transmission stability from being impaired when the toilet seat is rotated and the toilet seat is removed, and the toilet seat to be removed. An object of the present invention is to provide a toilet seat with a toilet seat that can ensure waterproofness even when detached.

SUMMARY OF THE INVENTION The present invention relates to a toilet with a toilet seat provided with a temperature detecting means and a seat detecting switch provided with a temperature detecting means and a seat detecting switch. It is characterized in that a non-contact signal transmission means for transmitting the seating information to the toilet body side in a non-contact manner is provided on the toilet seat. In order to transmit the temperature information and the seating information to the toilet body side in a non-contact manner, a connection cord and a connector are not required.

Here, as the non-contact signal transmission means, a means for transmitting a signal by electromagnetic induction using an electromagnetic induction coil can be suitably used. The temperature information and the seating information can be transmitted as a superimposed signal by transmitting this signal or by frequency multiplexing, whereby a plurality of information can be transmitted by one system of signal transmission means.

[0008] A resolution improving means for increasing the resolution of a specific temperature range among the temperatures detected by the temperature detecting means may be provided, or temperature information other than the specific temperature range among the temperatures detected by the temperature detecting means may be provided. Providing a means for applying a limiter is effective in increasing the accuracy of temperature information.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described. The toilet shown in FIG. 1 includes a local cleaning device 15 and a heater 20 built in the toilet seat 2 and is directly or directly attached to the toilet body 1. The toilet seat 2 rotatably mounted via the local cleaning device 15 is provided with the heater 2
0, a temperature detecting element 21 such as a thermistor, a seating detection switch 22 for detecting seating on the toilet seat 2, temperature information detected by the temperature detecting element 21, and a seating detection switch 22.
A signal generating / transmitting unit 24 for transmitting the seating information detected by the control unit, and a power supply unit 23. On the other hand, a control circuit 10 for controlling the operation of a local cleaning device 15 and a cleaning valve 16 for toilet water is provided on the toilet body 1 side, and the control circuit 10 configured by a microcomputer includes: The power transmitting unit 13 and the signal receiving unit 14 are connected. In the figure, reference numeral 12 denotes a power supply unit connected to an AC power supply.

The power supply from the toilet body 1 to the toilet seat 2 is performed by electromagnetic induction coupling using electromagnetic induction coils 31 and 32. That is, the power transmission unit 13 is configured by an oscillation circuit, and generates an electric current in the secondary electromagnetic induction coil 32 on the toilet seat 2 by exciting the primary electromagnetic induction coil 31 provided on the toilet body 1 side. The power supply unit 23 on the toilet seat 2 side supplies power to the heater 20 and the signal generation / oscillation unit 24 based on the current.

The temperature information and the seating information to be sent from the toilet seat 2 to the control circuit 10 are also stored in the electromagnetic induction coil 4 here.
1, 42. The signal generation / oscillation unit 24 outputs a signal including temperature information and seating information to the electromagnetic induction coil 4.
The temperature information and the seating information demodulated and restored by the signal receiving unit 14 are sent to the control circuit 10 via the signal receiving unit 14 of the toilet body 1 via the communication units 2 and 41. Control circuit 1
0 is the electromagnetic induction coil 3 according to the temperature information and the seating information.
The electric power supplied to the heater 20 through 1 and 32 is adjusted by, for example, duty ratio control.

The connection between the electromagnetic induction coils 31 and 32 and the connection between the electromagnetic induction coils 41 and 42 are non-contact, and the electromagnetic induction coils 31 and 41 are provided inside the toilet body 1 side.
What is necessary is just to arrange the electromagnetic induction coils 32 and 42 inside the toilet seat 2, and it is not necessary to expose an electric component such as a connection terminal to the outside at the connection portion, which is extremely advantageous in terms of waterproofness. It has become something.

Although the distance between the electromagnetic induction coils 31 and 32 and the distance between the electromagnetic induction coils 41 and 42 are as short as possible and the positional relationship between them is more accurate, the coupling efficiency is higher. Toilet bowl body 1 as described above
, The electromagnetic induction coils 31, 32, 41, 42 must be arranged to cope with this point. If the toilet seat 2 can be attached and detached in order to make the toilet seat 2 washable, this point must be taken into consideration.

For this purpose, as shown in FIG. 2, an arm 5 is rotatably provided on the side of the toilet body 1 so as to be coaxial with the rotation axis of the toilet seat 2, and the distal end of the arm 5 is An engaging means for engaging the toilet seat 2 is provided.
The arm 5 also rotates in conjunction with the opening and closing rotation of the arm. An electromagnetic induction coil 3 is attached to the tip of the arm 5.
1 and 41 are built in and these electromagnetic induction coils 31 and 41
Are respectively opposed to the electromagnetic induction coils 32 and 42 arranged in the toilet seat 2.

As the engagement means, as shown in FIG. 3, the tip of the arm 3 is slidably engaged with a groove 26 formed on the side surface of the toilet seat 2, or as shown in FIG. The distal end of the arm 5 which can be bent in an L-shape is fitted into a hole 27 provided on the side surface of the toilet seat 2, and the magnets 50, 50 (one of which may be a magnetic piece) which are attracted to each other as shown in FIG. And the toilet seat 2 can be used. In any case, the electromagnetic induction coils 31 and 41 in the arm 5 and the electromagnetic induction coils 32 and
It is preferable that the arm 5 and the toilet seat 2 be positioned relative to each other by a positioning portion such as a concave-convex fit as shown in FIG. 6 so that the positional relationship with the arm 42 is accurately determined.

FIG. 6 shows electromagnetic induction coils 31, 32, 41,
42 shows a specific example. Electromagnetic induction coil 3 for power transmission
Both of the U-shaped core 33 and the U-shaped core 33 are formed by winding a coil 34 via a coil bobbin 35, and the ends of both sides of the core 33 of the electromagnetic induction coil 31 are connected to the electromagnetic induction coil 32. The cores 33 are respectively opposed to the tips of both side pieces. In addition, since the electromagnetic induction coils 41 and 42 for signal transmission may be smaller than those for power transmission, the electromagnetic induction coils 31 and 3 are used here.
The two coil bobbins 35 are fixed to and opposed to each other so as to straddle between the tip portions on both sides of each core 33.

By the way, the information to be sent from the toilet seat 2 to the control circuit 10 of the toilet body 1 is temperature information and seating information, and the temperature information is not ON or OFF but has a continuous value. Therefore, transmission to the control circuit 10 is performed as follows. That is, the temperature information is given as a change in the cycle of the voltage or current of the AC voltage, and the seating information is superimposed on both signals in correspondence with the presence or absence of a signal of the AC voltage or current completely different from the cycle of the temperature information.
FIG. 7 shows a specific circuit example, and FIG. 8 shows waveforms. (A) in FIG.
(b) shows the voltage waveform at point A in FIG. 7, and (c) and (d) show the voltage waveform at point A in FIG.
FIG. 8A shows the voltage waveform at the point, and FIG. 8B shows the voltage when the seat switch 22 is on, and FIG. 8B shows the voltage waveform at the point B in FIG. Is the seat switch 2
8 (c) when the switch 2 is on, and FIG. 8 (d) when the seat switch 22 is off.

Alternatively, two frequency bands of an AC signal for temperature information in a certain temperature range may be prepared, and both frequency bands may be used according to seating information. FIG. 9 shows an example of a specific circuit in this case, and FIG. 10 shows waveforms. In the circuit constituted by the square wave generation circuit C1 and the Colpitts oscillation circuit C3, for example, when the seating switch 22 is turned on for temperature information of 0 ° C. to 50 ° C., as shown in FIG.
Signals corresponding to low frequencies of z to 2 kHz are represented by C in FIG.
Generated at the point, and 4 kHz when the seat switch 22 is off.
A signal corresponding to a frequency of z to 8 kHz is generated at the point C. The oscillation frequency is switched to the above-mentioned frequency band in accordance with the ON / OFF of the seat switch 22.

The temperature information may be represented by the period length of the positive voltage or the period length of the negative voltage of the alternating current, in addition to the period (frequency) as described above. In addition to the frequency division, the temperature information and the seating information may be combined by phase division. When the temperature detecting element 21 is a temperature-resistance converting element such as a thermistor as described above, the temperature detecting element 21 has the configuration shown in FIG.
It is preferable to connect a resistor R for improving the resolution in parallel as shown in FIG. The range required for temperature control of toilet seat 2 is 0-5.
Although it is 0 ° C., an important temperature range is temperature information for warming a person to a proper temperature when sitting on the toilet seat 2 and is approximately 25 to 5
In the range of 0 ° C, detailed temperature information is required.
What is necessary is just to know that the lower temperature is lower than the above range. On the other hand, when a thermistor is used as a temperature-resistance conversion element, it does not have a linear characteristic, but increases as the temperature increases.
The rate of change in resistance per ° C is small. However, by connecting the resistors R in parallel, the change in the combined resistance can be made closer to linear, so that the rate of change in the resistance in a required temperature range can be increased. Further, even if the temperature resistance conversion element (temperature detection element 21) is disconnected and becomes high in resistance, the limiter is activated by the parallel resistance R, and malfunction of the circuit can be prevented.

Regarding the above-mentioned limiter, FIG.
Alternatively, as shown in FIG. 12 (b), a constant voltage element D is connected to the temperature detecting element 21 which is a temperature resistance conversion element alone or in parallel, or as shown in FIG.
The resistors RL may be connected in series. Further, since there is variation in the temperature detection element 21 which is a temperature resistance conversion element, as a means for performing this adjustment, as shown in FIG.
It is preferable that all or a part of the parallel resistor R or the series resistor RL be a variable resistor VR so that the temperature resistor characteristic can be adjusted to a desired value by the variable resistor VR.

FIG. 15 shows an example of a modulation circuit C3 which modulates a signal obtained by synthesizing the temperature information and the seating information and supplies the signal to the electromagnetic induction coil 42. The modulation circuit C3 modulates the signal at a frequency higher than the frequency of the synthesized signal. The modulation circuit C3 using the grounded base Colpitts oscillation circuit is provided with a noise absorption capacitor Cx1 to cope with frequency fluctuation of the oscillation circuit due to the influence of the magnetic flux of the electromagnetic induction coils 31 and 32 for power transmission. Is stabilizing.

FIG. 16 shows an example of a specific circuit. In the circuit shown in the figure, when power is turned on, a current flows from the diode bridge DB1 to the capacitor C1 through the current limiting resistor, and a DC voltage is formed across the capacitor C1.
When the power is turned on, the capacitor C2 is charged by the resistor R3, and when the threshold value of the switching element FET is reached,
The switching element FET is turned on, and the drain voltage of the switching element FET starts to decrease. At this time, feedback is applied to the feedback winding L3 by an induced voltage from the primary winding L1 of the electromagnetic induction coil 31, so that the ON state of the switching element FET is deepened and a current flows. The current flowing through the switching element FET increases almost linearly, and at a certain current value, the transistor T2 is turned on by the voltage rise of the resistor R7 to remove the gate charge, so that the switching element FET is turned off. Resonance by the parallel circuit of L1 and capacitor C3 starts. And one
At the end of one cycle of resonance by the parallel circuit of the next winding L1 and the capacitor C3, the switching element FET is turned on again because the voltage induced in the feedback winding L3 reaches the potential for turning on the gate of the switching element FET. Thereafter, the operation shifts to stable oscillation by continuing the above operation.

In the above circuit, which is an inverter control circuit,
FET control is performed so that the resonance circuit stably supplies a constant output to the electromagnetic induction coil 32 on the secondary side, and the switching element FET can perform zero voltage switching. However,
In consideration of safety, when the power is turned on, the transistor T1 is in an active state, and the gate of the switching element FET is short-circuited to GND so that oscillation is not performed. The oscillation is started and stopped by a control circuit 10 comprising a microcomputer. It is controlled by the output. When the oscillation becomes abnormal due to some trouble, the resonance voltage changes. In this case, the transistor T3 in the normally-off state is turned on and a high signal is input to the control circuit 10, so that an abnormality is detected and the oscillation is stopped. Let it.

When resonance starts in the primary side resonance circuit, a voltage is induced in the electromagnetic induction coil 32 on the secondary side of the separation type transformer, and after rectification, power is sent to the heater 20. On the secondary side, a series circuit of capacitors C7 and C9 and resistors R13 and R14 is connected in parallel to each diode to prevent noise generated due to rectification. The above resistors R13 and R1
4 is determined from both the noise suppression effect and the self-loss, and the resistance value is set to an appropriate value by combining almost zero values. The capacitor C8 is provided in parallel with the electromagnetic induction coil 32 so that the energy from the electromagnetic induction coil 31, which is the primary side, can be effectively extracted to the secondary side.

As a power source for the non-contact signal transmission means,
Here, an auxiliary power supply circuit 2a is provided. In the auxiliary power supply circuit 2a, the coil winding induced voltage (AC) enters the input, and is rectified and smoothed by the diode D10, the resistor R16, and the capacitor C13, and the voltage of the Zener diode D11 (operational amplifier power supply) is formed. In addition, the capacitance of the capacitor depends on the presence or absence of the seat (on / off of the seat detection switch 22), and the resistance value of the temperature detecting element (thermistor) 21 changes with the change of the toilet seat temperature. A square wave is output from the operational amplifier. In order to transmit the square wave including the toilet seat information to the main body, the square wave is modulated by the next-stage Colpitts oscillation circuit 2c. Square wave generation circuit 2b
, The resistors R17 and R18 form a reference voltage of the CR oscillation circuit by voltage division. The inverting input terminal voltage of the operational amplifier is a non-seating time constant R20 + (R21 · SR) / (R
21 + SR) · C12, Seating time constant R20 + (R21
Charge / discharge is repeated at (SR) / (R21 + SR) · (C11 + C12), and the output of the operational amplifier becomes HI during a period of voltage lower than the non-inverting input terminal voltage, and the resistance divided voltage is input to the non-inverting input terminal voltage. When the voltage at the inverting input terminal of the operational amplifier exceeds the voltage at the non-inverting input terminal, the output is inverted. The width of the square wave is determined by the capacitors C11 and C12 and the temperature detecting element 21.
Changes the resistance value of the capacitor C1
1 and C12. 2 when seated and when not seated
By providing a kind of frequency table, information including the seating and temperature signals can be transmitted by one square wave. The range of the output frequency is, for example, when the resonance frequency is about 50 kHz and the signal carrier frequency is 2.5 MHz so that the capacitors C11 and C12 and the resistor R do not affect each other.
20, R21 are set. By inserting the resistor R21 in parallel with the temperature detecting element 21, the accuracy at the practical toilet seat operating temperature (around 20 ° C. to 50 ° C.) is increased. The resistor R20 is for protection when the temperature detecting element 21 is short-circuited. The Zener diodes D12 and D13 stabilize the amplitude of the square wave output with the Zener voltage. The capacitor C14 is for countering noise induced from the power section. The Colpitts oscillation circuit 2c is selected as a modulation circuit because of its advantages that the carrier frequency can be sufficiently higher than the inverter frequency, for example, 1 MHz or higher, that the antenna coil can be used as the circuit inductance, and that the waveform is a sine wave. ing. FIGS. 17 (a), (b), (c) and (d) show waveforms at points a to d in FIG.

Since the temperature information is demodulated on the signal receiving side of the toilet body 1 through a tuning circuit and a filter, the temperature information is sufficiently shifted from each band of the inverter frequency and the square wave signal frequency, and the carrier wave amplitude is hardly attenuated by the separation type transformer core. A frequency band around 2.5 MHz is selected. Tuning detection circuit 1
In a, the toilet seat information signal guided to the electromagnetic induction coil 41 by the electromagnetic induction from the electromagnetic induction coil 42 is tuned by the tuning capacitor C20 to increase the signal amplitude, and then the resonance frequency, for example, the 50 kHz band is changed to the high-pass filter C2.
Cut at 0, R25. Thereafter, the toilet seat signal is demodulated by a detection circuit including the diode D14, the capacitor C21, and the resistor R26. Further, the capacitor C22 and the resistor R
The DC component is cut by the filter constituted by 27. The signal is input to an operational amplifier, and the waveform is shaped by a comparator circuit. The toilet seat information square wave restored by the comparator circuit is input to the control circuit 10, and the control circuit 10 controls the inverter circuit output based on the information.

When the toilet seat 2 can be removed, it is necessary to detect this and stop the power transmission in terms of power consumption and the presence of foreign matter when metal foreign matter is placed nearby. This is preferable because heat generation can be eliminated. Therefore, when a detachment detection switch for the toilet seat 2 (a reed switch sensitive to a magnet can be suitably used) is provided on the toilet body 1 side, power transmission can be turned on / off according to the output of the detachment detection switch. Good.

When the detachment of the toilet seat 2 is detected by the presence or absence of a signal received by the signal receiving unit 14, the above-mentioned attachment / detachment detection switch becomes unnecessary. If the power transmission to the toilet seat 2 is completely stopped, the signal generation / transmission unit 24 on the toilet seat 2 side can send out a signal even when the toilet seat 2 is re-mounted because the power is not supplied. Accordingly, the control circuit 10 of the toilet body 1 cannot detect that the toilet seat 2 is attached. In order to prevent this, if it is detected that the toilet seat 2 has been removed, the power transmission may be stopped completely instead of completely stopping the power transmission. The heating of the heater 20 is negligible and sends enough power to operate the signal generating and transmitting unit 24. Specifically, the power supply to the electromagnetic induction coil 31 is changed from a continuous state to an intermittent power supply state by controlling the ON / OFF period of the inverter. Toilet seat 2
Is mounted, the signal generating / transmitting unit 24 operates to send a signal. In response to this, the toilet body 1 may switch to the normal power transmission mode.

When the user gives an instruction to turn off the heater through the input unit connected to the control circuit 10, the mode is set such that only the electric power sufficient to operate the signal generation / transmission unit 24 is transmitted, as in the above case. By doing so, the control circuit 10 can check the information on the attachment / detachment of the toilet seat 2 and the seating information. Of the power transmission and the signal transmission, it is difficult to employ a non-contact power transmission method other than the electromagnetic induction by the pair of electromagnetic induction coils 31 and 32 which are close to each other. Communication may be performed, or light (including infrared) communication may be performed.

[0030]

As described above, in the present invention, the toilet seat is provided with the non-contact signal transmitting means for transmitting the temperature information of the toilet seat by the temperature detecting means and the seating information by the seat detecting switch to the toilet body side in a non-contact manner. This eliminates the need for a connection cord and connector to transmit temperature information and seating information to the toilet body, and therefore the toilet body and toilet seat can be rotated when the toilet seat is rotated and the toilet seat is removed. The stability of the electrical connection between them is not impaired, and the waterproof property can be ensured even when the toilet seat is removed.

As the non-contact signal transmission means, a means for transmitting a signal by electromagnetic induction using an electromagnetic induction coil can be suitably used. The transmission efficiency can be increased and the electromagnetic waves can be reduced, and it is also advantageous in terms of noise resistance. Then, by transmitting this signal as a superimposed signal of the temperature information and the seating information, or by transmitting it by frequency multiplexing, it is possible to send a plurality of pieces of information by a single signal transmission means, and to simplify the circuit. Can be.

Further, a resolution improving means for increasing the resolution of a specific temperature range among the temperatures detected by the temperature detecting means may be provided, or temperature information other than the specific temperature range among the temperatures detected by the temperature detecting means may be provided. If a means for limiting the temperature is provided, the accuracy of the temperature information can be improved and the possibility of malfunction can be reduced.
