[0002]

2. Description of the Related Art Conventionally, a battery is used in a remote control device installed in a bathroom or the like, and when the battery is exhausted, the operation becomes uncertain even if various instructions are given. There is insufficient means to notify the user of this dead battery and to indicate the need for battery replacement, and the user may have operated the remote control whether each device such as a bubble bath in the bathroom has failed. There was a problem that it was difficult to determine whether the mistake was made or whether the battery was exhausted, causing anxiety. Further, in the conventional remote control device, when one operation switch becomes conductive due to some trouble such as a defective switch, the other switches do not work and the bubble bath or the like cannot be stopped immediately, which is a dangerous state. If there is a problem that the switch is in the conductive state and the signal keeps coming out due to some trouble, the pump etc. in the bubble bath suddenly starts up just by pointing the remote control, which is dangerous. There was a problem.

Next, FIG. 7 is a block diagram of a main circuit of the remote controller. In FIG. 7, a signal processing section connected to each of the operation switches 71 to 77 is provided on a substrate inside the remote controller main body 6. 20, the signal transmission circuit 21, and the voltage detection circuit 22 are provided, and the battery 9 that supplies electric power to the signal processing unit 20, the signal transmission circuit 21, and the voltage detection circuit 22.
Is provided. When any of the operation switches 71 to 77 is turned on, the instruction signal is sent to the signal processing unit 2.
0, the signal processing unit 20 is composed of a microcomputer, and each of the operation switches 71 to
This is a circuit for processing a signal output from 77 to generate a control code, and the signal processing section 20 is provided with a consumption signal sending means 20a. The voltage detection circuit 22 is a circuit that detects a voltage drop of the battery 9, and is composed of, for example, a constant voltage diode and a voltage comparison circuit.
The voltage of the battery 9 drops in accordance with the discharge current and the discharge time, and when it drops below the reference voltage, the voltage detection circuit 22 detects it and outputs a signal to the wear signal sending means 20a, and the wear signal sending means 20a wears. Generate a warning signal. This consumption warning signal is added to the control code when each signal operated by the operation switches 71 to 77 is converted into each control code by the signal processing unit 20. The signal transmission circuit 21 is a circuit that modulates the control code output from the signal processing unit 20 and drives the light emitting element 8 to emit infrared rays.

On the other hand, the substrate inside the holder 2 is provided with a signal receiving circuit 23, a signal processing section 24, and a signal external memory 25. The signal processing section 24 has a power source provided in the holder 2. Switch 12, lock switch 1
3, the filter medium washing switch 14 is connected, and the signal processing unit 24 has a display unit (LE which is turned on when the battery is exhausted).
D) 15 is connected, and as shown in FIG. 2, the display portion 15 is arranged under the filter medium cleaning switch 14 and is provided at a position easily visible from the front side of the holder 2. A liquid crystal display 3 is connected to the signal processing unit 24, and a pump unit 26 for ejecting bubbles into the bathtub 1 is also connected.

The signal receiving circuit 23 is a circuit for receiving signals modulated by infrared rays from the signal transmitting circuit 21 of the remote controller body 6 and demodulating the respective control signals. The signal processing unit 24 is a circuit for identifying each control code given from the signal receiving circuit 23, giving a necessary control signal to the pump unit 26, and displaying an operating condition on the liquid crystal display 3. , A microcomputer, and is provided with a consumption display means 24a and a consumption signal memory control means 24b. When the various control signals input from the signal receiving circuit 23 include a consumption warning signal, the consumption display means 24a detects the consumption warning signal and turns on the display unit (LED) 15. Is. Even if the consumption warning signal is not input from the signal receiving circuit 23, the display unit 15 is turned on when the consumption signal memory control means 24b gives an instruction.
Further, the signal external memory 25 is connected to the consumption signal memory control means 24b and stores the consumption warning signal once the consumption warning signal is given to the signal processing section 24. The consumption signal memory control means 2
Reference numeral 4b is for controlling the writing and reading of the signal external memory 25. When the signal receiving circuit 23 outputs a consumption warning signal, the signal is stored and held in the signal external memory 25, and the battery 9 is a new one. The consumption signal memory control means 24b clears (erases) the consumption warning signal stored in the signal external memory 25 when the consumption warning signal is no longer output from the remote controller main body 6 side.

In the remote controller constructed as described above, when the user turns on the operation switch 71 of the remote controller main body 6, the signal processing section 20 generates a jet-on control code. At this time, if no signal is output from the voltage detection circuit 22, the consumption signal transmission means 20a does not generate a consumption warning signal, and only the control signal for jet injection is transmitted from the signal transmission circuit 21. If the battery 9 is exhausted and the battery is dead at this time, when the voltage of the battery 9 becomes lower than the reference voltage, the voltage detection circuit 22 outputs a signal to the exhaustion signal sending means 20a and the signal processing unit 20. Adds an exhaustion warning signal to the jet-on control code. This signal is given to the signal transmission circuit 21, the control code and the consumption warning signal are modulated as a transmission signal, and the infrared rays are transmitted through the light emitting element 8.

When the signal receiving circuit 23 on the holder 2 side receives the infrared ray, the signal processing section 24 causes the signal receiving circuit 23 to operate.
If the output signal is identified, and this signal is a jet-in control code, the pump unit 26 is operated to eject bubbles into the bathtub 1. At this time, the signal processing unit 24 checks whether or not the control code includes a consumption warning signal, and when detecting the consumption warning signal, outputs the signal to the consumption display means 24a and the consumption signal memory control means 24b, The consumption display means 24a turns on the display unit 15, and the consumption signal memory control means 24b stores the consumption warning signal in the signal external memory 25.

Incidentally, not only when the operation switch 71 of the remote controller body 6 is turned on, but also when any of the other operation switches 72 to 77 is turned on, the control code corresponding to each of the switches 72 to 77. When the battery 9 is exhausted, an exhaustion warning signal will be sent each time the transmission is performed. Even when the power switch 12 of the holder 2 is turned off, the consumable display means 24a is configured to keep lighting the display unit 15 unless a new battery is exchanged and the signal is received. . Therefore, when the battery is dead, the display (LE
Since D) 15 is lit, the lit state can be visually confirmed to check the battery exhaustion, so that it is possible to accurately inform the user of the need for battery replacement and prevent malfunctions from occurring. It will be possible.

Next, referring to FIG. 8, a flow chart of the switch priority function control performed by the signal processing unit 20 in the remote controller main body 6 will be described. In step S1 of FIG. 8, when the voltage detection circuit 22 detects the voltage drop of the battery 9, the voltage drop flag is set in step S3. That is, as described above, the consumption signal sending means 20a
A consumption warning signal is output together with the control code to the signal transmission circuit 21 to generate a situation in which the consumption warning signal is transmitted to the holder side. If the voltage of the battery 9 has not dropped, the voltage drop flag is cleared in step S2.
The side display unit 15 is turned off, and a situation is generated in which the consumption warning signal stored in the signal external memory 25 is cleared.

Next, when the operation switch 71 is turned on in step S4, the other operation switches 72, 73, 7 are operated in the signal processing unit 20 in step S5.
Even when the signals from 4, 75, 76 and 77 are being output, the control codes corresponding to these operation switches 72 to 77 are cleared, and the control code for the operation switch 71 is generated in step S6. In addition, the control code is added with the signal indicating the presence or absence of the voltage drop flag in step S2 or step S3, and in step S7, the control code corresponding to the operation switch 71 and the voltage drop data are output to the signal transmission circuit 21. Then, in step S8, the signal is output to the signal transmission circuit 21. As a result, the signal transmission circuit 21 transmits the voltage drop data together with the control code to the holder 2 side.

As described above, in this example, the remote controller main body 6
The operation switches 71 to 77 are assigned priority orders, and the operation switch 71 is set to the highest priority order, and the operation switches 72, 73, 74, 75, 7
The order of priority is set to be lower in the order of 6,77. Therefore, even when the operation switches 72 to 77 are in the energized state due to a failure or leakage of water due to intrusion of water and these signals are input to the signal processing unit 20, the operation switch 71 having a high priority is turned on. At this time, the control code for the lower operation switch is cleared in the signal processing section 20, a control code for the operation switch 71 is generated and transmitted to the holder 2 side. Therefore, even when the operation switches 72 to 77 are in the energized state due to a failure or the like, the pump unit 26 of the bathtub 1
Can be stopped by operating the operation switch 71,
It is constructed so that the danger can be well avoided.

Incidentally, in step S9 of FIG.
When the operation switch 72 having the second highest priority is turned on, the operation switches 73, 74, 75, 76, 77
Even when the signal from any of the above is output, the signal processing unit 20 clears these data in step S10,
In step S11, a control code for the operation switch 72 is generated, and a signal indicating the presence or absence of a voltage drop flag is added and transmitted. Similarly, steps S12 and S1.
Also in S3 and S14, when the operation switch 73 is turned on, the control code for the lower switch is cleared to generate the control code for the operation switch 73, and a signal indicating the presence or absence of the voltage drop flag is added and transmitted. .
When the lowest operation switch 77 is turned on in step S15, a control code for this switch 77 is generated, and a signal indicating the presence or absence of a voltage drop flag is added to the control code and output.

Next, FIG. 9 shows another control flow chart executed in the signal processing section 20 in the remote controller main body 6. In FIG. 9, steps S21 to S are performed.
At 23, the presence or absence of the voltage drop of the battery 9 is detected in the same manner as described above, and when any of the operation switches 71 to 77 is turned on at step S24, this ON operation is performed at step S25. The signal indicating the presence / absence of the voltage drop flag is added to the control code for the generated switch, and it is determined in step S26 whether or not the data is the same as the data stored in the signal processing unit 20. In step S27, the data set in step S25 is stored in memory, and in step S28, the signal processing unit 2
The transmission counter in 0 is cleared to zero, and step S2
In step 9, the transmission counter starts counting, and in step S30, it is determined whether the transmission counter has counted 3 pulses. In the meantime, in step S31, the control code and the voltage drop data are sent to the signal transmission circuit 21.
To the signal transmission circuit 21 in step S32. As a result, the signal transmission circuit 21 transmits data to the holder 2 side with 3 pulses.

As described above, in the control of FIG. 9, when any of the operation switches 71 to 77 of the remote controller main body 6 is turned on, a signal in which the voltage drop data of the battery is added to the control code corresponding to the switch is set to 3 The pulse, that is, the signal is transmitted only for about 0.1 second, and then the control is performed in step S33 so as to clear the memory of the transmission data. When each operation switch 71 to 77 is pressed, the communication performance is The signal is sent to the holder 2 side in 3 pulses (approx.
Since it is only cut off in seconds, each operation switch 71
The battery 9 does not continue to be consumed even when ~ 77 is in an energized state due to a failure or intrusion of water, and
When each of the operation switches 71 to 77 is in the energized state and continues to be in the on state, the pump unit 26 is suddenly activated by simply pointing the remote controller main body 6 to the holder 2 side, and the bathtub 1
However, there is a risk that bubbles will be ejected to the inside, but since the signal is cut off after 3 pulses (about 0.1 seconds), such a situation can be prevented and safety is improved. Become.

The flowcharts shown in FIGS. 10 to 11 show the control in the signal processing section 20 in the remote controller main body 6, and the control shown in FIGS. The control shown in FIG. 9 is combined, and in step S41 to step S43, the voltage drop of the battery 9 is detected, and in step S44 to
In step S54, priorities are set for the operation switches 71 to 77 of the remote controller main body 6, and when a switch with a higher priority is turned on, when a signal from a lower switch is being input to the signal processing unit 20. Also, the data of this lower switch is cleared, the presence or absence of the voltage drop flag is added to the control code of the upper switch that has been turned on, and the result is output to the signal transmission circuit 21.
Even when power is on due to water intrusion, the upper operation switch 7
It is intended to avoid the danger by making it possible to stop the pump unit 26 and the like by 1. Also, FIG.
In step S55 to step S63 of 1, the transmission is terminated in 3 pulses (about 0.1 seconds) when any of the operation switches 71 to 77 is turned on, and the remote controller main body 6 is moved to the holder 2 side when the switch fails. The pump unit 26 and the like are controlled so that the pump unit 26 and the like are not actuated only by directing it toward the.

Although FIG. 12 shows another example of the remote controller main body 6, in FIG. 12, the remote controller main body 6 is further provided with a time operation switch 78. The second side is configured to generate time by time display or voice, and since this time operation switch 78 is an operation that does not affect the human body, it has the lowest priority and is set as described above. In the signal processing unit 20, the time operation switch 78
When any of the other high-priority operation switches 71 to 77 is turned on when the power is turned on due to a failure or the like, the data for the time operation switch 78 is cleared and the turned-on high priority is set. Operation switches 71-7
The control code for 7 is transmitted to the holder 2 side. Even when the time operation switch 78 is turned on, a signal of 3 pulses (about 0.1 seconds) is transmitted to the holder 2 side and is terminated.
