Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a local cleaning device provided in a toilet bowl to perform local cleaning of a human body after use.

(Prior Art) A local cleaning device is widely used in which a toilet nozzle is provided with a jet nozzle, and after washing the nozzle, the washing water is jetted from the jet nozzle to locally wash the toilet.

By the way, as this kind of local cleaning apparatus, as shown in FIG. 4, infrared rays are converted into a signal and transmitted from a transmission section 100 of a remote controller operation section, and this is received by a reception section 102, and at the same time, a transmission section 106 of a human body detection sensor 104. Another type of infrared signal generated from (FIG. 4 (B)) is received by the receiving unit 108 of the sensor 104, and when these two types of infrared signals are received, a signal from the control unit 110 causes Actuating the actuator 112 such as a solenoid valve, the ejection nozzle 114 (Fig. 4 (A))
There is a device that is designed to perform necessary operations such as spraying washing water from.

In the case of this type of local cleaning device, conventionally, the receiving unit 102 of the remote control device and the receiving unit 108 of the human body detection sensor 104 are respectively provided at different positions of the device main body, and each of them faces the different receiving window portions 114 and 116. It was arranged.

(Problems to be solved by the invention) However, in the case of arranging the receiving units in separate window portions in this way, the window portions are required in two places, which complicates the device configuration.

(Means for Solving the Problem) The invention of the present application has been made in order to solve such a problem, and the gist of the first solving means is, therefore, the transmitter of the remote controller operation unit and the human body detection sensor. Infrared and other signals emitted from the respective transmitters are received by the receiver and the sensor receiver of the remote control device arranged facing the reception window, respectively, and the actuators are operated to wash water from the nozzle for locally cleaning the human body. In a local cleaning device that performs a predetermined operation such as squirting, the receiving portion and the sensor receiving portion of the remote control device are arranged at the same position and the same receiving window portion is used as a common receiving window portion. Especially.

(Operation and Effect of First Solving Means) As described above, according to the present invention, the reception unit of the remote control device and the reception unit of the human body detection sensor, which are conventionally separate from each other, are arranged at the same position, and one reception window is shared. It was made to do.

According to the invention of the present application, since only one reception window is required, the complexity of the device configuration is eliminated.

(Second Solving Means) The gist of the second solving means of the present application is that the receiving unit of the remote control device is also used as the sensor receiving unit.

(Operation and Effect of Second Solving Means) According to the second solving means of the present application, one receiving unit is sufficient for the receiving unit of the remote control device and the receiving unit of the human body detection sensor which are separately provided in the related art. .

In the conventional remote control type local cleaning device, infrared rays are emitted from both the transmitter (light emitting part) of the remote controller and the transmitter (light emitting part) of the human body detection sensor, and it is necessary to receive both of them. Therefore, the two receivers are provided separately.

However, since the infrared rays from the transmitter of the remote control device and the infrared rays from the transmitter of the human body detection sensor are both pulsed and emitted as a signal, it is not always necessary to provide the receivers separately. Therefore, in the present invention, the same receiving unit is used as both the receiving unit of the remote control device and the receiving unit of the human body detection sensor.
As a result, only one receiving unit, which has been conventionally required for two units, will be sufficient.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIG. 1, 10 is a local cleaning apparatus of this example, which includes a main body 12 and
With a jet nozzle 16 provided on the toilet bowl 14, the washing water is jetted upward from the jet nozzle 16 based on the opening and closing of an electromagnetic valve provided on the passage of the washing water, so that the local area of the human body is washed. Has become.

The local cleaning device 10 has a remote control device and a human body detection sensor 15 for detecting the presence or absence of a human body sitting on the toilet bowl 14. Reference numeral 18 denotes a transmitter of this remote control device, from which infrared rays are pulsed and transmitted, and the receiver 22 is arranged facing the window 20 (FIG. 1B) of the main body box. It will be received at. The received infrared signal is input to the control unit 24.

As shown in (B), the human body detection sensor 15 has an infrared ray transmitting portion 26 and an infrared ray receiving portion 28, which are arranged so as to face the common window portion 20. From the transmitter 26, a pulsed infrared signal of a different type from that from the transmitter 18 of the remote controller is emitted toward the human body 32,
The reflected light is received by the receiver 28. The received infrared rays are converted into electric signals and input to the upper control unit 24. Then, based on the electric signal, the control unit 24 determines whether or not there is a reflected light amount equal to or more than a predetermined fixed light amount, and determines whether or not there is a human body. Thus, when there is a signal from the remote control transmitter 18 and a human body detection signal from the human body detection sensor 15, the electromagnetic valve is opened to cause the jetting nozzle 16 to eject the washing water, or to warm the temperature. Each actuator 30 is operated so as to operate the wind heater and perform a predetermined operation such as drying of the cleaning section.

FIG. 2 is a flow chart showing the execution contents of control by the control unit 24. As shown in the figure, in this example, first, in step S1, the remote control transmitter 18
From the human body detection sensor 15 when it is determined that an infrared signal corresponding to each operation switch has been received by the receiving unit 22, and the switch operation has been performed. To emit infrared rays from the transmitter 26 (S2). And the receiving part of the sensor 15
When an infrared ray of a certain amount or more is received at 28 (S
3) Judging that a human body is present, actuate the actuator such as the electromagnetic valve (S4), and perform the necessary operation corresponding to the switch of the remote control operation unit.

Next, in S5, whether or not the stop switch of the remote control operation unit is pressed, specifically, whether or not an infrared signal corresponding to the stop switch is emitted from the remote control transmission unit 18 and this is received by the reception unit 22 is determined. When it is determined that the stop switch is operated, the operation of the device including the actuator, the sensor, etc. is stopped (S6).

On the other hand, when the operation unit of the remote control device is not operated at all, the process returns to S2 and repeats the steps of S2 to S5.

In S3, when the receiving unit 28 of the sensor 15 does not receive a predetermined amount of infrared rays, that is, when it is determined that there is no human body, it is determined that the remote control operating unit has been operated by a mischief or the like, and the operation stop state of the device is determined. To maintain.

As described above, in this example, the control unit 24 determines whether or not the operation unit of the remote control device is operated, and only when there is an operation, the sensor 15 is activated to detect the human body. That is, the sensor 15 performs the human body detecting operation only when it is determined that it is necessary. This eliminates the need for the sensor 15 to continue to work all the time, and accordingly, the power consumption by the sensor 15 is reduced and the life of the sensor 15 is improved.

Further, since the receiving unit 22 of the remote control device and the receiving unit 28 of the sensor 15 do not need to work at the same time, it is possible to use them as one receiving unit.

FIG. 3 shows a specific example thereof, and in this example, the receiving unit 34 serves as both the receiving unit of the remote control device and the receiving unit of the human body detection sensor 15 as shown in the drawing.

In this way, by using one receiving unit 34 as the receiving unit of the remote controller and the receiving unit of the sensor 15, the number of receiving units can be reduced.

Although the embodiments of the present invention have been described in detail above, the present invention can be configured in other forms.

For example, the above-mentioned control content by the control unit is merely an example of the present invention, and it is possible to execute the control in other modes, and to operate the device by transmitting or receiving a signal other than infrared rays. It is also possible to
The present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention.
