に手間がかかるという欠点があつた。(Conventional technology and problems) Conventionally, when filling a heating appliance and its hot water passage with water, the heating operation switch is turned on, water is injected into the expansion tank, and the circulation pump is activated by the float switch installed in the expansion tank. Turn on and off to fill with water, but at this time the burner also ignites, so if the gas valve is open, the burner will ignite. However, the water passing through the heat exchanger is still mixed with air, and the circulation is not smooth, so it may become stale inside the heat exchanger.
The burner may flicker. Also, if the gas valve is closed, the burner will not ignite even though it will ignite, so the controller will detect an abnormality of ignition failure and stop the entire appliance, so reset the power and try again to detect the abnormality. It is necessary to fill water until the appliance stops, and then reset it again.For these reasons, there is a drawback that filling the heating water circuit with water is time consuming.

をもうけた器具を提供することにある。 The purpose of the present invention is to provide a heating appliance and an appliance equipped with a dedicated switch for filling the hot water passageway with water, which can be easily filled with water.

温出力手段Ａを構成している。 FIG. 2 shows a part of the electric circuit in the control unit, in which the water filling switch 12 and the heating operation switch 13 are connected, a self-holding circuit 21 that holds the input signal from the switch, and a self-holding circuit 21 that holds the input signal from the switch, and a A thermistor control circuit 22 is provided that controls the load of the burner 2 and the like by increasing and decreasing the load. 17 is a resistor connected in parallel with the thermistor 3, and a normally open relay contact 16 and a normally closed relay contact 20 are connected in series. Further, a normally open relay contact 19 is connected in series to the thermistor 3. 15 and 18 are relays, which are turned ON by input from water filling sweets 12.
The relay 15, which is turned on, drives the relay contact 16 to close, and the relay 18, which is turned on by the input of the heating operation switch 13, closes the relay contact 19 and at the same time drives the relay contact 20 to open. The relay 15, the relay contact 16, and the resistor 17 constitute a pseudo hot water temperature output means A.

となり何ら支障はない。 During normal use, when heating operation switch 13 is turned on, relay 18 is turned on and relay contact 19 is closed, and at the same time as the thermistor 3 is connected to the thermistor control circuit 22, the circulation pump 6 is driven. When the hot water temperature is low, the burner 2 is caused to perform an ignition operation to heat the heat exchanger 1. The heated hot water is circulated to the radiator 9. However, as mentioned above, there are problems with performing such operations when filling with water after construction is completed. Therefore, when filling the circulation circuit with water, turn on the water filling switch 12. When the water filling switch 12 is turned on while filling water into the expansion tank 8, the relay 15 is turned on, and the contact 16 driven by it is turned on. During normal use, combustion is controlled by the resistance change of the hot water tap thermistor 3, and the burner is turned on and off when the temperature detected by the hot water tap thermistor is 85℃, the burner is extinguished, and when the temperature detected by the hot water tap thermistor is 85℃, it is re-ignited.
The control is performed, and here the resistor 17 is
Thermistor resistance above 70℃ (e.g. 80℃
If the resistance value is set equal to the resistance value of The circuit can be easily filled with water. When the water filling is completed, press the water filling switch 12 again and turn on the relay 15.
Turn OFF and leave relay contact 16 open. By the way, if you forget to release the water filling switch 12, the relay contact 16 will remain closed. However, when the relay 18 is turned on by turning on the heating operation switch 13, the relay contact 20 opens, so only the thermistor 3 is connected to the thermistor control circuit 22, and there is no problem.

た。(Effects of the invention) As described above, the present invention includes a heat exchanger heated by a burner, a hot water temperature detection section, a burner and a control section that ignite and extinguish the water according to the temperature of the hot water detected there. In a heater consisting of a pump that circulates hot water, the control section is equipped with a water filling switch and is connected to an operation switch, both switches are connected to a self-holding circuit that holds input signals of both switches, and the self-holding circuit A first relay for the water filling switch and a second relay for the operation switch are connected to the first relay.
A contact that closes when turned on and a resistor constitute a pseudo hot water temperature output means, and the pseudo hot water temperature output means is connected to a thermistor control circuit that controls a load such as a burner, and there is a connection between the pseudo hot water temperature output means and the thermistor control circuit. Since we have provided a contact that opens when the second relay is turned on, we can pseudo-change the hot water temperature detection using the pseudo hot water temperature output means so that the controller does not enter ignition operation when the water filling switch is turned on. Only the pump has a float switch.
Since it is operated in conjunction with ON and OFF, the heating water circuit can be easily filled with water.

にするためである。 In addition, as in the embodiment, the water filling switch 12 is not just a pump ON/OFF switch, but can be reset by the water filling switch itself, the heating operation switch, or the main power supply OFF, so there is no need to worry about forgetting to release the water filling switch. Malfunctions can also be prevented. In other words, turn on the heating operation switch.
When turned on, the relay for the heating operation switch turns on, which opens the contact connecting the thermistor control circuit and the pseudo hot water temperature output means, which automatically turns the water filling switch off. .
