Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device that allows an outdoor liquid heating device placed outside the bathroom to be operated inside the bathroom.

The applicant of this application had previously applied for this kind of device in 1983.
According to No. 000894, for example, as shown in FIG. 1, the communication of light beams between optical fibers A and B is interrupted by an optical switch element E attached to an operating knob D in a bathroom C, and a bathroom is installed outdoors using an optical method. Pot device F
We proposed a system that can be remotely controlled. According to this, there is no need for electrical wiring in the bathroom C, causing no insulation defects, and the operating load on the operating knob D is also lightened, which eliminates the need for electrical or mechanical devices of this kind that are conventionally used. Although this type of device has the effect of reliably resolving the problems caused by this type of device, the widespread use of this type of device has been slow due to the high cost of optical fiber.

The purpose of the present invention is to provide an inexpensive remote control device that eliminates the need for electrical wiring in the bathroom and reduces the operational load.

That is, the present invention provides a remote control device that allows the operation of an outdoor liquid heating device 2 to be confirmed in a bathroom 3 via an optical fiber 1. It is characterized in that it is carried out by a pneumatic switch 5 via a pneumatic transmission member, and the optical fiber 1 is housed inside the pipe 4.

The present invention will be explained below using an example in which the present invention is implemented in a remote control device for an outdoor liquid heating device. In FIG. 2, the heating device 2 includes a heat exchanger 6 and a burner 7 connected to the bathtub. Reference numeral 8 denotes a push-lock switch, which has a mechanism that keeps the contacts closed with the first push and opens them with the next push. A light emitter 9 is connected in parallel with the push-lock switch 8, and a combustion control section 10 is connected in series. When the push-lock switch 8 is closed, the light emitter 9 emits light, and the solenoid valve 11 is opened to supply gas to the burner 7 and the spark plug 12 ignites it. Thereafter, the solenoid valve 11 is held open by the flame detection element 13. Therefore, the hot combustion air of the burner 7 heats the water in the heat exchanger 6 leading into the bathtub. The next push opens the push-lock switch 8, stops the light emitter 9 from emitting light, and closes the electromagnetic valve 11, stopping combustion. On the other hand, it is installed in bathroom 3,
When the operating knob 15 formed of a flexible member having a through hole 14 is pushed so as to close the through hole 14 with a finger, air pressure is applied to the inside of the pipe 4 which is formed airtight and penetrates the room wall 16 in the bathroom 3. is transmitted and reaches the air pressure switch 5 installed outdoors, and the pin 19 interlocking with the diaphragm 18 moves against the spring material 17.
A pushing force is applied to the push-lock switch 8.
Inside the pipe 4, an optical fiber 1 is installed with one end facing the display section 16 close to the operation knob 15 and the other end facing the light emitter 9, which prevents the airtightness inside the pipe 4 from being impaired. It is accommodated without any problems. Therefore, the light emitter 9
The operation of the heating device 2 is displayed on the display unit 16 provided in the bathroom 3 through the optical fiber 1.

As explained above, the operation of the heating device 2 is controlled by a remote control device using the pneumatic switch 5, and the operation is controlled via the optical fiber 1 in the bathroom 3.
Since the optical fiber 1 is housed in the pipe 4, it is not only cheaper than the above-mentioned system using two optical fibers, but also compared to the conventional example. This has the effect of simplifying installation work.

Although the present invention has been explained using an example in which the heating device 2 is implemented in a bathtub, it is not limited to this, and an outdoor-installed water heater may also be used. However, it is also possible to set the other end of the optical fiber 1 opposite to the flame of the burner 7 and display this flame inside the bathroom 3. In such a case, the flame of the light emitter 9 This has the effect of ensuring reliable display regardless of malfunctions or the like.

As described above in detail, the present invention provides a remote control device that allows the operation of the outdoor liquid heating device 2 to be checked in the bathroom 3 via the optical fiber 1. Operation, pipe 4
The pneumatic switch 5
It is characterized in that the optical fiber 1 is housed inside the pipe 4, which eliminates the need for electrical wiring in the bathroom, reduces the operating load, and
This has the practical effect of providing an inexpensive remote control device.
