FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. 1 to 4, the same components as those in FIG. 5 are denoted by the same reference numerals, and description thereof will be omitted. FIG. 1 shows a sanitary washing device A provided with various functions such as a local washing / drying function, an automatic closing function of a toilet lid 2, and a deodorizing function in a toilet room. In FIG. This is a remote control device for operating the sanitary washing device A, which is installed at a predetermined position (where the user can easily operate while sitting on the toilet seat 3).

The remote controller 9 includes switches 10a and 10 for remotely operating various functions of the sanitary washing device A.
b,..., and a transmission unit 1 for transmitting the command set by the switches 10a, 10b,.
1. A human body detection sensor 12 for irradiating infrared rays, ultrasonic waves, or the like to detect the presence or absence of a user in a toilet room is provided.

The human body detection sensor 12 irradiates the toilet bowl 3 with infrared rays or ultrasonic waves, and detects the presence or absence of a user of the sanitary washing device A based on the reception time of the reflected light. In a state of sitting on the toilet seat 3 (or in a state of standing in front of the toilet 1 at the time of small use), the infrared rays or ultrasonic waves radiated on the toilet 1 are used by a user sitting on the toilet seat 3 (use of the user standing in front of the toilet 1). Can be reflected and received in a relatively short time, but when the user is not sitting on the toilet seat 3 (not standing in front of the toilet bowl 1), the irradiated infrared rays and ultrasonic waves are used for sanitary washing. Since the light is reflected by the side wall of the device A or the entrance / exit door (a portion facing the remote control device 9), the time from irradiation to reception of light is inevitably longer than when there is a user. .

As a result, the human body detecting sensor 12 can easily detect whether or not there is a user who uses the sanitary washing device A shown in FIG. 1 by detecting the light receiving time. And the switches 10a, 1
, The transmission unit 11, and the human body detection sensor 12 are electrically connected to a control unit provided in the remote control device 9 and described later.

On the other hand, a receiving unit 13 for receiving a signal transmitted from a transmitting unit 11 provided in the remote control device 9 is provided at an upper portion of a front surface of the control device 4 provided in the sanitary washing device A. It is electrically connected to a control unit (not shown). The remote control device 9 and the control unit provided in the control device 4 are both configured using a microcomputer including a CPU and the like.

The receiving unit 13 provided in the remote control device 9 does not need to be installed at the upper front of the control device 4, and may be located at a position where the signal transmitted from the transmitting unit 11 of the remote control device 9 can be satisfactorily received. If so, there is no particular problem with the mounting position. When the receiving unit 13 is not installed at a position where the signal transmitted from the transmitting unit 11 can be directly received, the signal transmitted by the transmitting unit 11 is, for example, a wall or a floor in a toilet room,
Alternatively, reception may be performed after reflection on a ceiling or the like.

Further, the sanitary washing device A shown in FIG. 1 includes a remote control device 9 and a control device 4 installed on a wall surface in the toilet room.
Although the signal transmission unit 11 and the reception unit 13 are provided to transmit and receive signals, respectively, the remote control device 9 and the control units provided in the control device 4 are directly connected to each other via a signal line, and the signals are transmitted and received. It goes without saying that transmission and reception may be performed in a wired manner.

FIG. 2 is a block diagram schematically showing the configuration of the human body detecting device of the present invention comprising the remote controller 9 and the controller 4. As described above, the switches 10a, 10b,...
1, the human body detection sensor 12 is electrically connected to the control unit 14, and the receiving unit 13 installed in the control device 4
Is electrically connected to the control unit 15 inside. The control section 15 is electrically connected to a plurality of loads 16a, 16b,... Which operate various functions of the sanitary washing device A.

Next, the operation of the human body detecting device when the user sits on the toilet seat 3 will be described with reference to the flowchart of FIG. First, with the user sitting on the toilet seat 3 of the sanitary washing device A shown in FIG. 1, for example, the local washing switch 10a on the remote control device 9 installed on the wall surface in the toilet room is turned on (step in FIG. 3). S ₁ ) Then,
The control unit 14 of the remote control device 9 transmits a signal corresponding to the turning on of the switch 10 a from the transmission unit 11 to the sanitary washing device A.

The control unit 15 (see FIG. 2) receives this signal by the receiving unit 13 installed at the upper front of the control device 4.
Drives a load (for example, an electric motor 16a for extending the nozzle 6 or an electromagnet 16b for opening a water supply valve, not shown) for executing the local washing function, and jets the washing water appropriately to the local area after the toilet. .

As a result, the user can clean the local area cleanly, and the cleaning operation is performed until the ON state of the local cleaning switch 10a turned on by the user is released or until a predetermined time elapses. Continued. Then, when the switch 10a is released or when a predetermined time elapses, the control unit 14 stops the local cleaning operation from the transmission unit 11 to the reception unit 13 provided in the control device 4. Transmit the signal of

Based on the signal received by the receiving unit 13, the control unit 15 in the control unit 4 returns the nozzle 6 extended by rotating the electric motor 16a, for example, in the reverse direction to the original position. By stopping the supply of electricity to the water supply valve and closing the water supply valve in the open state, the cleaning operation of the local part is terminated.

Further, when the part washing switch 10a is turned on (step S _1), the control device 14 in the remote control unit 9 activates the timer built, to measure the predetermined time (e.g., 1 minute) (step S _2). And
When the timer measures the predetermined time (Step S _3), to turn on this by powering the human body detection sensor 12 provided in the remote control device 9 (Step S _4).

When the human body detection sensor 12 is turned on, for example, infrared rays or ultrasonic waves are irradiated onto the toilet 1 from the remote control device 9 shown in FIG. whether) is detected seated on the toilet seat 3 (step S _5). As a result, if the user is still seated on the toilet seat 3, the remote controller 9
The control unit 14 stops power supply to the human body detection sensor 12 and turns it off (step S ₆ ).

[0034] After that performs measurement for a predetermined time (1 min) back to the step S ₂ again, after, repeating the same operation as described above. In other words, the human body detection device of the present invention shown in FIG. 2 requires a predetermined time (one minute) after the user turns on the local cleaning switch 10a after turning on the switch 10a, for example, after the user turns on the local cleaning switch 10a. After the elapse, the human body detection sensor 12 provided in the remote control device 9 is turned on (normally, after the local cleaning switch 10a is turned on,
After a lapse of minutes, the user is likely to leave the toilet room), and the presence or absence of the user is detected.

At this time, if it is detected that the user is still sitting on the toilet seat 3, the human body detection sensor 12 is immediately turned off to minimize power consumption. Then, the human body detection sensor 12 once turned off is turned on again after a lapse of a predetermined time (1 minute), and determines again whether or not the user is sitting on the toilet seat 3.

As a result, if the user is still seated, the human body detection sensor 12 is turned off again. As described above, the human body detection sensor 12 is provided every predetermined time (one minute) as long as the user is sitting on the toilet seat 3.
2 is turned on to detect the presence or absence of a user.

Further, in step S ₅ illustrated in FIG. 3,
As a result of detecting the presence / absence of a user, when detecting a state in which the user is separated from the toilet seat 3 (a state in which there is no user of the sanitary washing device A), the controller 14 of the remote controller 9 shown in FIG.
Stops the power supply to the human body detection sensor 12 and turns it off (step S ₇ ), and transmits a signal to the sanitary washing device A from the transmitter 11 to close the toilet lid 2 (step S ₇ ). ₈ ).

The control unit 15 shown in FIG. 2 receiving this signal at the receiving unit 13 drives the electric motor 16d for closing the toilet lid 2 (or an electromagnet for closing the toilet lid 2) 16d to drive the toilet lid 2. Is automatically closed. After closing the service lid 2, after opening the toilet lid 2 manually by entering again the user flights chamber of the sanitary washing device A, to introduce a local cleaning switch 10a of the remote control device 9 (Step S ₁ ) until the human body detecting sensor 12 maintains the oFF state, then, if the local cleaning switch 10a is turned on, sequentially repeating the step S ₃ and subsequent operation.

When the toilet lid 2 is closed by the electric motor 10d, when the user manually opens the closed toilet lid 2, the connection state between the electric motor 10d and the toilet lid 2 is released. Alternatively, the electric motor 10d is rotated in a direction opposite to the direction in which the toilet lid 2 is closed, and the toilet lid 2 is opened. Furthermore, when the user manually closes the toilet lid 2,
The connection between the toilet lid 2 and the electric motor 10d can be easily released, or the electric motor 10d can be manually rotated in the forward direction.

If the washing mode is set to return to the initial state (a steady state desired at the time of starting the function) when the toilet lid 2 is closed, the sanitary washing device A can be more conveniently used. Can be used.

As described above, the human body detecting device shown in FIG.
Since the off state of the human body detection sensor 12 that was turned off when the user of the sanitary washing device A no longer exists was configured to be maintained until the user turned on the local cleaning switch 10a again, the human body was not used. The detection sensor 12 is not turned on, so that power consumption can be suppressed and the life of the sensor 12 can be extended.

In the standby state of the sanitary washing device A,
Since the toilet lid 2 is automatically closed, an unpleasant odor in the toilet bowl 1 can be well blocked by the toilet lid 2 and the odor can be prevented from diffusing into the toilet room.

Next, another embodiment of the present invention will be described with reference to the flowchart of FIG. In FIG. 3, description is operation of steps S ₂₁ ~ step S ₂₈ is identical to the steps S ₁ ~ Step S ₈ shown in FIG. 2 will be omitted.

That is, when the toilet lid 2 is closed,
Since the sanitary washing device A is in a so-called standby state in which the toilet seat 3 is not used, for example, the power supplied to the heater for heating the toilet seat 3 is reduced to lower the heat retaining temperature of the toilet seat 3 by a certain temperature (for example, when the toilet lid 2 is closed). Therefore, the toilet seat 3 can be maintained at a constant temperature with low power consumption even in the winter season when the ambient temperature is lowered), and a local drying function for drying a local part after washing and a function for deodorizing the toilet room are in operation. At some point, this may be stopped. Further, the power supply to all loads other than the minimum required load (for example, a heater for heating the toilet seat 3) may be stopped.

As described above, by reducing the power consumption of the sanitary washing device A in the standby state, the sanitary washing device A can be operated with the minimum required amount of electric power, thereby suppressing unnecessary power consumption. Is economical. Note that the power saving function of the sanitary washing device A is not limited to transmitting a power saving signal from the remote control device 9 but detects that the toilet lid 2 is closed on the sanitary washing device A side. , The power saving mode of various functions may be set.
