Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating device for household equipment such as a water heater.

[0002]

2. Description of the Related Art Conventionally, for example, in a gas fan heater, by pressing two operation switches at the same time (for about 1 second), a locked state (child lock) is established, and normal operation commands are not accepted. .

Then, the lock is released only when the "off" operation is performed by the restriction release switch, and the normal state where the operation instruction signal can be input and returned is returned.

[0004]

However, in the conventional structure, in order to enter the locked state, the user has to remember the operating method once and intentionally perform it whenever necessary, and release it. Therefore, there was a problem that the regulation release switch had to be operated every time.

SUMMARY OF THE INVENTION The first object of the present invention is to solve the above-mentioned problems, and it is a first object of the present invention to automatically invalidate an operation instruction when the operation body is separated from the mount.

A second object is to reduce the current consumption when used while being biased to either the locked state or the unlocked state.

A third object is to enable a specific operation even in the locked state.

[0008]

In order to achieve the above object, a first means of an operating device according to the present invention is an operation switch for inputting an instruction signal to an instrument, and an input operation of the operation switch as a signal. An operation main body having an IC for receiving and an output circuit for outputting an instruction signal from the IC to the instrument,
It is provided with a mounting base for accommodating the operation main body, and an input control switch for disabling the output of the instruction signal when the operation main body is detached from the mounting base and enabling it when the operation main body is mounted.

A second means of the present invention is such that the IC in the first means enables the input regulation switch to be regularly monitored.

Further, according to the third means of the present invention, even when the operation main body is detached from the mounting base and the input regulation switch acts to invalidate, the specific input condition or the signal of the specific operation switch is applied. As long as the IC has a function of sending an instruction signal to the output circuit.

[0011]

With the above-mentioned first means, the operating device of the present invention outputs the instruction signal by the action of the input regulation switch even if the operation main body is operated by a child mischieving the operating main body from the mount. Can be disabled, and driving due to mischief of equipment can be prevented.

Further, in the second means, the current consumption can be reduced even when the operating device by the first means is used while being biased to either the locked state or the unlocked state.

Further, according to the above-mentioned third means, even when the operation main body is removed from the mount and is in a locked state,
Only specific operations can be performed.

[0014]

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

FIG. 1 is a remote controller (hereinafter, also referred to as a remote controller) of a water heater as an embodiment of the present invention, and FIG. 2 is an internal circuit diagram thereof. In both figures, a remote control main body 5 as an operation main body is attached to a mounting base 2, and the mounting base 2 is fixed to a wall 1. A magnet 3 is embedded and mounted in the mounting base 2, and the remote controller main body 5 has a reed switch 4 built in at a position facing the magnet 3. The reed switch 4 is turned on when an electric switch (not shown) is turned on / off by the force of the magnet 3 and the magnet 3 approaches, that is, when the remote controller main body 5 is housed in the mounting base 2. The reed switch 4 is incorporated in the circuit as shown in FIG. 2, and the IC 6 can know the state of the reed switch 4 as a Hi / Low signal by turning the reed switch 4 on and off.

The remote controller body 5 communicates between the output circuit 8 and a control circuit of a water heater (not shown). As shown in FIG. 3, switches 9 and 10 for turning on / off the operation of the water heater are provided on the front surface of the remote controller body 5, and a temperature control switch 11 and a temperature for lowering the temperature to set the hot water temperature. A temperature adjusting switch 12 for raising the temperature, a liquid crystal display 13 for displaying the set temperature and the like are provided.

According to the above construction, when the remote controller main body 5 is mounted on the mounting base 2, the reed switch 4 is turned on by the force of the magnet 3 and the IC 6 inputs the Low signal. At this time, if the program in the IC 6 receives signals from the various switches 9 and 11 when the Low signal is input, the operation can be performed at any time. on the other hand,
When the remote control body 5 is removed from the mounting base 2, the influence of the magnet 3 disappears, the reed switch 4 is turned off, and the IC 6 inputs a Hi signal (a program that does not accept any switch operation when the Hi signal is input) It doesn't work.
Then, the liquid crystal display 13 indicates that the lock is applied.

As described above, according to this embodiment, the mounting base 2
Since the magnet 3 and the reed switch 4 as the input control switch are built in each of the remote control main body 5 and the remote control main body 5, the remote control main function can be locked by separating or storing the remote control main body 5 from the mounting base 2. It can be canceled. Of course, the program of the IC 6 may be operated when the Hi signal is input, or another component such as a light receiving element may be used instead of the reed switch 4 to eliminate the magnet 3.

Further, the transistor 14 having the structure shown in FIG.
Is periodically turned on for only a short time, and a program for detecting the signal input of the reed switch 4 at that timing is set, so that when the reed switch 4 is turned on, the reed switch 4 normally flows constantly. The amount of current can be reduced.

Further, by making the IC 6 accept only the operation of the operation switch 10 in the locked state, the importance and effect of the switch can be improved.
Limit the temperature control switch 11 and 12 to the temperature control range from the unlocked state to the range where there is no risk of burns.
It is also possible for C6 to accept.

[0021]

As is apparent from the above description, in the operating device according to the first aspect of the present invention, the operation main body is provided with the input restriction switch, and when the operation main body is removed from the mounting base, the input restriction switch operates. , The IC detects the signal and invalidates the output of the instruction signal, so the power is not turned off while preventing the operation operation of the equipment by removing the operation main body from the mounting base due to mischievous operation of children etc. It is possible to know the state of the equipment, leaving the display function of.

According to the second aspect of the present invention, when the operation main body is left detached from the mounting base, or the opposite is left attached, whichever continues for a long period of time, the current is usually always supplied to the input regulation switch. With this configuration, the current consumption is reduced where the current continues to flow, so that there is an effect that the life of the battery power source can be extended, for example.

Further, according to the third aspect, there is an effect that, for example, the hot water supply set temperature is limited to a safe range, or only the temperature control switch is locked to enable safer use.
