Further, the switch 196 of the second position detecting means 102 is provided at the bottom of the other lock recess (not shown) of the fireplace body 2 in relation to the second lock means, and the lock pin 92 is inserted into this lock recess. When the second locking means is brought into the locked state, the lock pin 92 presses the switch 106, and thus the second position detecting means 102 detects the first angular position of the fireplace body 2.

  This fireplace is controlled as follows using the detection signals of the first and second position detection means 100 and 102. In FIG. 8, detection signals from the first and second position detection means 100 and 102 are sent to the controller 108. Further, the fireplace operation panel 110 (see also FIG. 1) controls an ignition switch 112 for burning the combustion burner 28, a fire extinguishing switch 114 for stopping the combustion of the combustion burner 28, and a combustion heat amount. And an operation signal from the ignition switch 112, the fire extinguishing switch 114, and the heat amount volume 116 is sent to the controller 108. The control controller 108 includes an ignition signal generating means 118 for generating an ignition signal, a fire extinguishing signal generating means 120 for generating a fire extinguishing signal, and a forced fire extinguishing signal generating means 122 for generating a forced fire extinguishing signal. Contains. The combustion burner 28 includes an ignition device 124 for igniting the fuel gas, an electromagnetic on-off valve 126 for supplying and stopping the supply of the fuel gas, and a flow rate for adjusting the supply flow rate of the fuel gas. A control valve 128 is provided.

  With this configuration, when the ignition switch 112 is ignited, the ignition signal generation means 118 of the control controller 108 generates an ignition signal based on the operation signal from the ignition switch 112, and based on this ignition signal As the ignition device 124 operates, the electromagnetic on-off valve 126 is opened, and the fuel gas supplied through the pipe 52 is combusted. When the heat quantity volume 116 is operated in such a combustion state, the opening degree of the flow control valve 128 is adjusted in accordance with the operation amount of the heat quantity volume 116, thereby the fuel gas supplied to the fuel burner 28. The supply amount is adjusted. Further, when the fire extinguishing switch 112 is extinguished, the fire extinguishing signal generating means 120 of the control controller 108 generates a fire extinguishing signal based on the operation signal from the fire extinguishing switch 114, and the electromagnetic on-off valve 126 is closed based on the fire extinguishing signal. Thus, the supply of the fuel gas through the pipe 52 is stopped, and the combustion of the combustion burner 28 is finished.

  In this embodiment, the control is further performed as follows based on the detection signals of the first and second position detection means 100 and 102. The first position detection means 100 detects the first angular position of the fireplace body 2 (in this embodiment, the first lock means 88 is held in a locked state), or the second position detection means 102 is the fireplace body 2. When the second angular position is detected (in this embodiment, the second locking means is held in the locked state), the ignition signal generating means is allowed to generate an ignition signal, that is, the combustion burner 28 is allowed to burn. It is configured to be. Therefore, when the fireplace body 2 is located at the first angular position (or the second angular position), when the operator performs an ignition operation on the ignition switch 112, the ignition signal generation means 118 of the controller 108 generates an ignition signal. As described above, the combustion burner 28 is burned. On the other hand, when the fireplace body 2 is not located at either the first angular position or the second angular position (for example, located at a position between the first angular position and the second angular position) Even if the operator ignites the ignition switch 112, the ignition signal generating means 118 does not generate an ignition signal, and the combustion burner 8 does not burn.

  Further, when the fireplace main body 2 is not positioned at either the first angular position or the second angular position (for example, rotating and moving from the first angular position toward the second angular position), forced fire extinguishing is performed.
