Description

請求項３の発明は、複数のガスバーナと、複数のガスバーナへのガス供給の元となる共通のガス供給路と、共通のガス供給路から分岐して各ガスバーナに続く分岐路と、を備え、降圧回路及び主電力路から駆動電流が供給される駆動対象負荷として、分岐路に設けられるとともに駆動軸の回転角度に応じて分岐路の開度を設定するモータを有する。
請求項４の発明は、複数のガスバーナと、複数のガスバーナへのガス供給の元となる共通のガス供給路と、共通のガス供給路から分岐して各ガスバーナに続く複数の分岐路と、を備えており、降圧回路及び主電力路から駆動電流が供給される駆動対象負荷として、複数の分岐路にそれぞれ設けられ、駆動軸の回転角度に応じて分岐路の開度を設定する複数のモータと、少なくとも共通のガス供給路に配置され、当該共通のガス供給路の開閉を切り替える元電磁弁と、が設けられている。
このように複数のモータ及び元電磁弁が設けられる構成は電力消費が大きくなりやすく、電池寿命がより問題になるため、このような構成のものに対して本発明の特徴を適用すればより一層有用である。また、この構成では、電池電圧が相対的に低くなった場合、複数のモータ及び元電磁弁に対する駆動電圧の供給元を一斉に切り替えることができ、電池寿命を延ばしつつこれら全ての駆動部を安定的に動作させ得る構成を、複雑な構成や制御を伴うことなく実現できる。 The invention of claim 3 includes a plurality of gas burners, a common gas supply path that is a source of gas supply to the plurality of gas burners, and a branch path that branches from the common gas supply path and continues to each gas burner, A drive target load to which drive current is supplied from the step-down circuit and the main power path includes a motor that is provided in the branch path and sets the opening of the branch path according to the rotation angle of the drive shaft.
The invention of claim 4 includes a plurality of gas burners, a common gas supply path as a source of gas supply to the plurality of gas burners, and a plurality of branch paths branched from the common gas supply path and continuing to each gas burner. A plurality of motors that are provided in a plurality of branch paths as drive target loads to which drive current is supplied from the step-down circuit and the main power path, and set the opening degree of the branch paths according to the rotation angle of the drive shaft And an original solenoid valve that is disposed at least in the common gas supply path and switches between opening and closing of the common gas supply path.
Since the configuration in which a plurality of motors and original solenoid valves are provided in this manner tends to increase power consumption and the battery life becomes more problematic, if the features of the present invention are applied to such a configuration, the characteristics of the present invention are further increased. Useful. In addition, with this configuration, when the battery voltage becomes relatively low, it is possible to simultaneously switch the supply source of the drive voltage to the plurality of motors and the original solenoid valve, and to stabilize all these drive units while extending the battery life Can be realized without complicated configuration and control.
