Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a wireless remote control device, and more specifically, a remote control device that allows the user to arbitrarily set a unique system address between a transmitter and a receiver. It is related to the device.

[Background of the idea]

Figure 6 shows the flow rate of an instantaneous water heater by remote control.
This shows a block diagram of a remote control device for controlling water temperature, etc., in which a shower head 1 is provided with a transmitter 2 and a transmitting antenna 3, an instantaneous water heater 4 is provided with a receiver 5, and instructions from the transmitter 2 are provided. The flow rate, water temperature, etc. of the instantaneous water heater 4 are controlled via the receiver 5.

When multiple such systems are installed in the same location, each system's transmitter 2 and receiver 5 must be assigned a unique system address to prevent malfunctions caused by operating other systems. has been done.

Normally, the transmitter 2 uses an encoder IC and the receiver 5 uses a decoder IC to set the system address, and by changing the logic level of multiple address terminals of these encoder ICs and decoder ICs, a unique system address code can be set for each. is being carried out.

By the way, in order to maintain waterproofness of the transmitter/receiver installed in such a hot water shower device, as shown in FIG. The entire board 7 on which is attached is molded with molding agent 8, and the address code setting is done before molding with molding agent 8.
This is done by cutting the conductive pattern 7a connected to the power supply line of the board 7 to which the address terminal 6a of the IC 6 is soldered at the position indicated by arrow A.

However, in the case of such remote control devices, the address is set when the transmitter/receiver is manufactured and then molded with a molding agent, so the user cannot change the address code and the transmission If the machine breaks down, a transmitter that matches the existing address code must be purchased. Another problem is that it is necessary to check whether the address codes of the transmitter and receiver set at the time of product shipment match.

[Purpose of invention]

The present invention solves the above problems by allowing the user to set the communication code as desired.
Moreover, by maintaining waterproofness, the object is to provide a remote control device that can be used even when remote control is performed while wet with water, such as in a hot water shower device, for example.

[Example of idea]

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a sectional view of a transmitter of a remote control device showing an embodiment of the present invention.

This transmitter is attached to the shower head 10, and includes an IC 11 in which the FM modulation circuit, amplifier circuit, etc. that make up the transmitter are integrated, and a power battery 1.
2, Encoder IC 13, Operation instruction switch 1
4 etc. are assembled on the board 15, and the encoder
The IC 13 is arranged so that its address terminal 16 is located at one end of the substrate 15. Then, the board 15 is stored in the transmitter storage recess 10a of the shower head 10 with the mounting surface of the encoder IC 13 facing upward, and the operation instruction switch 14
The recess 10a is covered by a substrate 17 having a hole 17a into which the push button 14a is fitted.

In addition, after installing various parts on the board 15, this transmitter is installed at the address terminal 16 of the encoder IC 13.
All of the parts except for the conductive pattern 18 of the substrate 15 to which it is connected are molded with a molding agent 19.

As shown in FIG. 2, this conductive pattern 18 is formed in a shape with a constricted center part, and by cutting this constricted part 18a, the logic level can be changed and an address code can be set. .

Note that the conductive pattern 18 is cut by the user, and after cutting the constricted portion 18a to match the address of the receiver (not shown), the entire conductive pattern 18 is filled with molding agent, and the molding agent is dried. Then, the board 17 is bonded to the transmitter storage recess 10a using an adhesive or the like.

That is, when assembling the transmitter to the shower head 10, the user does not set the address code, and the surface of the constriction 18a of the conductive pattern 18 for setting the address code is not filled with molding agent 19. This constriction 18
A can be easily cut, and furthermore, after setting the address code, the conductive pattern 18 is molded over the entire surface with a molding agent.
The transmitter is now completely waterproof.

Therefore, according to this embodiment, there is no need to specify an address when replacing a transmitter, and transmitters can be easily replenished.

Furthermore, since the user can confirm the address code of the receiver and set the address of the transmitter, the receiver can reliably receive radio waves from the transmitter.

Note that since the constricted portion 18a of the conductive pattern 18 in the above-described embodiment is in close contact with the substrate 15,
The cutting will be done with a knife, but in this case there is a risk of accidentally cutting the adjacent constricted part 18a, so as shown in FIG. 3, the conductive pattern 20
If the jumper wire 21 is connected to the address terminal 16 using a jumper wire 21, the jumper wire 21 can be cut with pliers or the like, so that the address code can be easily set without cutting other jumper wires.

Further, as shown in FIG. 4, the conductive pattern 24
and address terminals 16 with pins 25 erected, respectively.
A pin hole 26 that is press-fitted with both pins 25, 25,
Shortening socket 27 made of conductive material having 26
By connecting the conductive pattern 23 and the address terminal 16, the address code can be set even more easily.

[Summary of the idea]

As explained above, the present invention is a remote control system which includes a circuit board 15 on which a communication code setting circuit 13 is mounted and which is molded and housed in a case, and which has a code setting change means in a communication code setting location. In the control device, the code setting changing means is a plurality of conductive patterns 18 or 20 having a disconnection pattern that can be selectively disconnected, and a portion other than the disconnection pattern is molded. It is a device.

[Effect of idea]

Therefore, according to the present invention, since the code setting changing means can be operated, the user can check the address code and set an arbitrary address code without having to set the address code in advance. Therefore, even if a replacement is required due to a failure or the like, there is no need to obtain one with a specific address code set.
