DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water floor heating device for heating by flowing hot water through a heat radiating pipe on a floor.

[Prior art]

As shown in FIG. 3, the hot water floor heating device heats hot water in a boiler 1 to boil it, and circulates this hot water between a lung heat pipe 2 in the indoor floor and the boiler 1 by a circulation pump 3. It is formed. A temperature control circuit that works by detecting the floor temperature or room temperature or the temperature of the floor and the room is provided in a controller 6 attached to a wall or the like in the room, and a valve 5 provided in the circulation pipe 4 is connected to a signal from the temperature control circuit. By opening and closing according to the above, the temperature of the heating is controlled by flowing or stopping the flow of the hot water through the heat radiating pipe 2.

However, in the conventional controller 6, the main switch of the entire apparatus cannot control the output signal to the boiler 1 or the circulation pump 3 to turn on / off the power supply. And a switch for the circulating pump 3 need to be provided, and these switches need to be operated, respectively, and there is a problem that operability is poor. Further, in the conventional apparatus, the operation of the circulation pump 3 is continued even while the valve 5 is closed in response to the signal from the temperature control circuit and the flow of the hot water to the heat radiation pipe 2 is stopped. There is also a problem that the life of the device is shortened and power consumption is wasted. The present invention has been made in view of the above points, and an object of the present invention is to provide a floor heating device that has good operability, can prolong the life of a circulation pump, and can reduce power consumption. It is the purpose.

[Means for Solving the Problems]

The present invention includes a boiler 1 for heating hot water, a circulating pump 3 for circulating hot water between a radiating pipe 2 on the floor and the boiler 1, and a valve 5 provided on a circulating pipe 4 through which hot water is circulated. In the hot water floor heating device, the controller 6 disposed in the room includes a main switch Sw and a boiler relay Ry ₁ that controls on / off of energization of the boiler 1 in conjunction with on / off operation of the main switch Sw. , When the main switch Sw is on, the power supply standby state
A valve relay Ry ₂ for opening and closing the on-off by valve 5 by a signal from tc, on-off control the power supply to the valve relay Ry ₂ on and off in conjunction with the actuating circulation pump 3 pump it is characterized in that comprising providing a use relay Ry _3.

[Operation]

In the present invention, the valve relay when the can control the energization of the boiler 1, also the valve 5 is closed in conjunction with the operation of the main switch Sw which is provided to the controller 6 by the boiler relay Ry ₁ The power supply to the circulation pump 3 can be stopped by Ry ₂ and the pump relay Ry ₃ to stop the operation of the circulation pump 3.

【Example】

Hereinafter, the present invention will be described in detail with reference to examples. As shown in FIG. 1, the hot water floor heating apparatus includes a boiler 1 for heating and boiling hot water, and a circulation pump 3 for circulating the hot water between a heat radiating pipe 2 of the indoor floor and the boiler 1. A valve 5 formed of a motor-operated valve, a thermal valve, or the like is attached to a circulation pipe 4 between the boiler 1 and the heat radiation pipe 2. Also, the controller 6 is a heat radiation pipe 2
Is mounted on a wall of a room provided with the. The controller 6 is provided with a main switch Sw. As shown in the circuit diagram of FIG. 2, the main switch Sw is turned on in conjunction with turning on the main switch Sw, and is turned off in conjunction with turning off the main switch Sw. A boiler relay Ry ₁ is incorporated in the controller 6. The boiler relay Ry ₁ is electrically connected to the boiler 1 so that the boiler 1 is energized by being turned on, and the boiler 1 is stopped by being turned off. An output signal is output. The Yes and valve relay Ry ₂ are operated via the output relay the signal from the temperature control circuit Tc is provided to the controller 6, the valve 5 is energized when the relay Ry ₂ is turned on for the valve to the valve control circuit Vc open the valve relay Ry ₂ have the energization to the valve control circuit Vc turned off so that the valve 5 is stopped closed. As shown in the circuit diagram of FIG. 2 the valve relay Ry ₂ becomes the first standby state by the main switch Sw is turned on, the state main switch Sw is not made the current supply to the turned off valve control circuit Vc become. Furthermore the controller 6 is provided with a pump relay Ry _3. The pump relay Ry ₃ is turned on in conjunction by being turned on the valve relay Ry ₂ as shown in the circuit diagram of FIG. 2, the valve relay Ry ₂ are turned off in conjunction by being turned off Things. Pump relay Ry ₃ is Yes electrically connected to the circulation pump 3, so that energization of the circulation pump 3 by being turned on is made, also the energization of the circulation pump 3 by being turned off is stopped The output signal is output as follows. In the floor heating apparatus configured as described above, when the main switch Sw is first turned on, the boiler relay Ry ₁ is also turned on, so that the boiler 1 is energized and the boiler 1 starts operating. 1 automatically burns and hot water is boiled to a predetermined set temperature. The room and temperature control circuit Tc is activated, such as by comparing the detected temperature and the indoor set temperature of the bed temperature, the detected temperature is sent a signal to the valve relay Ry ₂ when lower than the room temperature setting valve relay Ry ₂ Is turned on, the valve control circuit Vc is energized, and the valve 5 is opened. And this time is the start of energization of the valve relay Ry ₂ relay for simultaneously pump as turned on Ry ₃ circulating pump 3 is also turned on, hot water circulation pump 3 is boiled in a boiler 1 operates It is supplied to the heat radiation pipe 2 and circulated. Conversely detected temperature is ready valve relay Ry ₂ a signal is sent to valve relay Ry ₂ are off when higher than the room temperature setting, the valve 5 energization of the valve control circuit Vc is stopped is closed Then, the circulation of the hot water to the heat radiation pipe 2 is stopped. And this time valve relay Ry ₂ have the energization of pump relay Ry ₃ at the same time as the turn off even turned off to the circulation pump 3 is stopped, operation of the circulation pump 3 is stopped.

【The invention's effect】

As described above, according to the present invention, a controller arranged in a room includes a main switch, a boiler relay for controlling on / off of energization to the boiler in conjunction with on / off operation of the main switch, When the switch is on, the power is put into a standby state and the signal from the temperature control circuit turns the valve on and off to open and close the valve, and the power to the circulation pump is turned on in conjunction with the on / off operation of the valve relay.・ Because a pump relay that controls off is provided, the power supply to the boiler can be controlled by the function of the boiler relay according to the operation of the main switch, and the power supply to the circulation pump is controlled by the function of the pump relay. This eliminates the need to provide and operate a switch for a boiler or a circulation pump, thus improving operability. , And the addition can be stopped circulating pump and stops energizing the circulating pump while closing the valve by the action of relay valve relay and pump,
It is possible to prevent unnecessary operation of the circulation pump, maintain the life of the circulation pump for a long time, and reduce power consumption.
