このような加熱調理器において、電池に代えて商用電源を電力供給源として使用することが考えられる。その場合、加熱調理器には、電池に代えて、商用電源に接続される電力供給手段が備えられる。ガス加熱ユニットは、その電力供給手段から供給される電力を利用して動作する。 In such a cooking device, it is conceivable to use a commercial power source as a power supply source instead of a battery. In that case, the cooker is provided with a power supply means connected to a commercial power source instead of the battery. The gas heating unit operates by utilizing the electric power supplied from the electric power supply means.

ただし、一般的に、商用電源の電圧は乾電池等の電池の電圧に比べて大きい。そのため、商用電源を電力供給源とする加熱調理器において、利用者が誤ってガス加熱ユニットの可触部に触れた場合、電池が電力供給源である場合に比べて、感電の可能性が高くなる。商用電源を電力供給源とする加熱調理器を採用する場合において、利用者がガス加熱ユニットの可触部に触れたとしても、感電を防止し得る対策が求められている。 However, in general, the voltage of a commercial power source is larger than the voltage of a battery such as a dry battery. Therefore, in a cooking cooker that uses a commercial power source as a power supply source, if the user accidentally touches the touchable part of the gas heating unit, there is a higher possibility of electric shock than when the battery is the power supply source. Become. In the case of adopting a cooking device that uses a commercial power source as a power supply source, there is a demand for measures that can prevent electric shock even if the user touches the touchable part of the gas heating unit.

本明細書では、商用電源を電力供給源とする加熱調理器において、利用者がガス加熱ユニットの可触部に触れたとしても、感電を防止できる技術を提供する。 The present specification provides a technique for preventing electric shock even if a user touches a touchable portion of a gas heating unit in a cooking device using a commercial power source as a power supply source.

本明細書が開示する加熱調理器は、商用電源に接続される電力供給手段と、前記電力供給手段から供給される電力を利用して動作するガス加熱ユニットと、絶縁手段と、を備える。前記ガス加熱ユニットは、ガスを燃焼させて加熱を行うガス加熱部と、前記ガス加熱部による加熱を制御するガス加熱制御部と、前記ガス加熱部の近傍において、利用者が接触可能な態様で露出している可触部であって、前記ガスへの点火を行う点火部と、前記ガスの燃焼炎を検知する炎検知部と、のうちの少なくとも一方を含む前記可触部と、を有している。前記絶縁手段は、前記電力供給手段と前記可触部の間において絶縁性能を発揮可能な手段である。 The cooking cooker disclosed in the present specification includes a power supply means connected to a commercial power source, a gas heating unit that operates by using the power supplied from the power supply means, and an insulating means. The gas heating unit is in a manner in which a user can contact a gas heating unit that burns gas to heat the gas, a gas heating control unit that controls heating by the gas heating unit, and a gas heating unit in the vicinity of the gas heating unit. An exposed touchable portion having an ignition portion that ignites the gas, a flame detection portion that detects a combustion flame of the gas, and the touchable portion including at least one of them. are doing. The insulating means is a means capable of exhibiting insulating performance between the power supply means and the touchable portion.

上記の構成によると、加熱調理器は、電力供給手段と可触部の間において絶縁性能を発揮可能な絶縁手段を備える。絶縁手段を備えることにより、利用者がガス加熱ユニットの可触部に触れたとしても、利用者が感電する事態は生じ難い。従って、上記の構成によると、商用電源を電力供給源とする加熱調理器において、利用者がガス加熱ユニットの可触部に触れたとしても、感電を防止することができる。 According to the above configuration, the cooking cooker is provided with an insulating means capable of exhibiting insulating performance between the power supply means and the touchable portion. By providing the insulating means, even if the user touches the touchable part of the gas heating unit, it is unlikely that the user will get an electric shock. Therefore, according to the above configuration, in a cooking device using a commercial power source as a power supply source, even if the user touches the touchable portion of the gas heating unit, electric shock can be prevented.

前記絶縁手段は、前記電力供給手段と前記可触部の間において、二重絶縁相当の絶縁性能以上の絶縁性能を発揮可能な手段である。

The insulating means is a means capable of exhibiting an insulating performance equal to or higher than that of double insulation between the power supply means and the touchable portion.

ここで、「二重絶縁」とは、基礎絶縁及び付加絶縁の両方で構成される絶縁のことを意味してもよい（ＪＩＳ規格参照）。二重絶縁の絶縁性能は、基礎絶縁の絶縁性能に比べて高い。「基礎絶縁」とは、感電に対する基礎的な保護を行うために、充電部（即ち、電気系統と接続されている部分）に施した絶縁のことを意味してもよい（ＪＩＳ規格参照）。「付加絶縁」とは、基礎絶縁が破損した場合に感電に対する保護を行うために、基礎絶縁に追加された独立の絶縁のことを意味してもよい（ＪＩＳ規格参照）。 Here, "double insulation" may mean insulation composed of both basic insulation and additional insulation (see JIS standard). The insulation performance of double insulation is higher than that of basic insulation. "Basic insulation" may mean insulation applied to the charging section (ie, the section connected to the electrical system) to provide basic protection against electric shock (see JIS standard). "Additional insulation" may mean independent insulation added to the foundation insulation to provide protection against electric shock if the foundation insulation is damaged (see JIS standard).

この構成によると、絶縁手段は、電力供給手段と可触部の間において、二重絶縁相当の絶縁性能以上の絶縁性能を発揮可能である。そのため、電力供給手段と可触部の間に基礎絶縁１個分のみの絶縁性能を発揮する絶縁手段が備えられている場合に比べて、高い絶縁性能を発揮可能である。そのため、上記の構成によると、利用者が感電する事態をより適切に防止することができる。 According to this configuration, the insulating means can exhibit an insulating performance equal to or higher than that of double insulation between the power supply means and the touchable portion. Therefore, higher insulation performance can be exhibited as compared with the case where an insulation means that exhibits insulation performance of only one basic insulation is provided between the power supply means and the touchable portion. Therefore, according to the above configuration, it is possible to more appropriately prevent the situation where the user receives an electric shock.

前記絶縁手段は、二重絶縁相当の少なくとも２個の独立した絶縁構造を含んでもよい。 The insulating means may include at least two independent insulating structures equivalent to double insulation.

ここで、二重絶縁相当の少なくとも２個の独立した絶縁構造とは、少なくとも２個の基礎絶縁構造のことであってもよいし、少なくとも１個の基礎絶縁構造と少なくとも１個の付加絶縁構造との組合せであってもよい。例えば、１個の基礎絶縁構造は、一次側と二次側の配線を直接接続させない電源変換部（いわゆるトランス）を設ける構造を含む。この構成によると、絶縁手段は、二重絶縁相当の絶縁性能以上の絶縁性能を適切に発揮することができる。 Here, at least two independent insulating structures corresponding to double insulation may be at least two basic insulating structures, or at least one basic insulating structure and at least one additional insulating structure. It may be a combination with. For example, one basic insulation structure includes a structure provided with a power conversion unit (so-called transformer) that does not directly connect the wiring on the primary side and the secondary side. According to this configuration, the insulating means can appropriately exhibit the insulating performance higher than the insulating performance equivalent to the double insulation.

前記絶縁手段は、少なくとも１個の強化絶縁構造を含んでもよい。 The insulating means may include at least one reinforced insulating structure.

ここで、「強化絶縁」とは、感電に対し二重絶縁と同程度の保護を持つ、充電部に施した単一の絶縁のことを意味してもよい（ＪＩＳ規格参照）。例えば、強化絶縁構造は、一次側と二次側の配線を直接接続させない電源変換部（いわゆるトランス）を設けるとともに、一次側と二次側の配線をいずれの箇所においても所定距離以上離隔させる構造を含む。この構成によると、絶縁手段は、二重絶縁相当の絶縁性能以上の絶縁性能を適切に発揮することができる。 Here, "reinforced insulation" may mean a single insulation applied to the charging portion, which has the same degree of protection against electric shock as double insulation (see JIS standard). For example, the reinforced insulation structure is provided with a power conversion unit (so-called transformer) that does not directly connect the wiring on the primary side and the secondary side, and the wiring on the primary side and the secondary side are separated by a predetermined distance or more at any location. including. According to this configuration, the insulating means can appropriately exhibit the insulating performance higher than the insulating performance equivalent to the double insulation.

上記の加熱調理器は、前記電力供給手段から供給される電力を利用して動作する電気加熱ユニットをさらに備えてもよい。前記電気加熱ユニットは、電気を熱に変換して加熱を行う電気加熱部と、前記電気加熱部による加熱を制御する電気加熱制御部と、を有していてもよい。 The above-mentioned cooking cooker may further include an electric heating unit that operates by utilizing the electric power supplied from the electric power supply means. The electric heating unit may have an electric heating unit that converts electricity into heat for heating, and an electric heating control unit that controls heating by the electric heating unit.

ここで、「電気加熱部」とは、電熱器（例えばシーズヒータ等、電気をジュール熱に変換する加熱器）、ＩＨ加熱器（即ち、電気を利用して発生する磁力を利用して加熱対象物（鍋等）を誘導加熱する加熱器）等、電気を熱に変換して加熱対象物を加熱可能な各種加熱部を含む。 Here, the "electric heating unit" is an electric heater (for example, a sheathed heater or the like, a heater that converts electricity into Joule heat), an IH heater (that is, a heating target using magnetic force generated by using electricity). It includes various heating parts that can heat an object to be heated by converting electricity into heat, such as a heater that induces and heats an object (pot, etc.).

この構成によると、加熱調理器が、商用電源を電力供給源とする電気加熱ユニットとガス加熱ユニットとを両方備える場合において、利用者がガス加熱ユニットの可触部に触れたとしても、感電を防止することができる。 According to this configuration, when the cooking cooker includes both an electric heating unit and a gas heating unit whose power supply source is a commercial power source, even if the user touches the touchable part of the gas heating unit, an electric shock is generated. Can be prevented.

前記ガス加熱ユニットと前記電気加熱ユニットのうちの第１のユニットは、前記電力供給手段に電気的に接続されており、前記ガス加熱ユニットと前記電気加熱ユニットのうちの前記第１のユニットとは異なる第２のユニットは、前記第１のユニットに電気的に接続されていてもよい。 The gas heating unit and the first unit of the electric heating unit are electrically connected to the power supply means, and the gas heating unit and the first unit of the electric heating unit are connected to each other. The different second units may be electrically connected to the first unit.

この構成によると、第２のユニットが動作できない状況が発生する場合（例えば、第２のユニットに不具合が発生する場合）においても、電力供給手段に電気的に接続されている第１のユニットを継続して動作させることができるため、第２のユニットが動作できない間に、加熱調理器を用いた調理が全く行えない事態の発生を防止することができる。 According to this configuration, even when a situation occurs in which the second unit cannot operate (for example, when a problem occurs in the second unit), the first unit electrically connected to the power supply means can be used. Since it can be continuously operated, it is possible to prevent the occurrence of a situation in which cooking using the cooking device cannot be performed at all while the second unit cannot operate.

前記ガス加熱ユニットと前記電気加熱ユニットは、それぞれ、前記電力供給手段に電気的に接続されていてもよい。 The gas heating unit and the electric heating unit may be electrically connected to the electric power supply means, respectively.

この構成によると、ガス加熱ユニットと電気加熱ユニットとのうちの一方が動作できない状況が発生する場合（例えば、当該加熱ユニットに不具合が発生する場合）においても、電力供給手段に電気的に接続されている他方の加熱ユニットを継続して動作させることができるため、一方の加熱ユニットが動作できない間に、加熱調理器を用いた調理が全く行えない事態の発生を防止することができる。 According to this configuration, even when one of the gas heating unit and the electric heating unit cannot operate (for example, when a malfunction occurs in the heating unit), it is electrically connected to the power supply means. Since the other heating unit can be continuously operated, it is possible to prevent the occurrence of a situation in which cooking using the heating cooker cannot be performed at all while one heating unit cannot operate.

As shown in FIG. 1, the electric heating unit 10 is directly connected to the power supply means 4. The electric heating unit 10 has a built-in conversion unit for converting a high-voltage AC power source (in this case, a commercial power source (for example, AC200V)) into a DC power source that can be used by the electric heating unit 10. The electric heating unit 10 heats using a DC power source after being converted by the built-in conversion unit.

電気加熱制御部１２は、電気加熱部１０による加熱を制御する制御部である。図１に示されるように、電気加熱制御部１２は、電力供給手段４と電気的に接続されている電力供給系統から、基礎絶縁構造３０を介して電力供給を受けて動作する。基礎絶縁構造３０については後で詳しく説明する。 The electric heating control unit 12 is a control unit that controls heating by the electric heating unit 10. As shown in FIG. 1, the electric heating control unit 12 operates by receiving electric power from the electric power supply system electrically connected to the electric power supply means 4 via the basic insulation structure 30. The basic insulation structure 30 will be described in detail later.

ガス加熱ユニット８も、電力供給手段４から供給される電力を利用して動作する加熱ユニットである。上記の通り、ガス加熱ユニット８は電気加熱ユニット６に電気的に接続されている。即ち、ガス加熱ユニット８は、電気加熱ユニット６を介して、電力供給手段４からの電力の供給を受けている。ガス加熱ユニット８は、ガス加熱部２０と、ガス加熱制御部２２と、可触部２４と、を有している。 The gas heating unit 8 is also a heating unit that operates by using the electric power supplied from the electric power supply means 4. As described above, the gas heating unit 8 is electrically connected to the electric heating unit 6. That is, the gas heating unit 8 is supplied with electric power from the electric power supply means 4 via the electric heating unit 6. The gas heating unit 8 has a gas heating unit 20, a gas heating control unit 22, and a touchable unit 24.

ガス加熱部２０は、ガスを燃焼させることにより、載置されている加熱対象物（例えば鍋）を加熱するための加熱部である。図示しないが、ガス加熱部２０は、ガスを供給するためのガス供給路、供給されたガスを燃焼させるバーナ等を有している。ガス加熱制御部２２は、ガス加熱部２０による加熱を制御する制御部である。可触部２４は、ガス加熱部２０の近傍において、利用者が接触可能な態様で露出している部分である。可触部２４は、ガスへの点火を行うための点火部２６と、ガスの燃焼炎を検知する炎検知部２８とを有している。図１に示されるように、ガス加熱部２０、ガス加熱制御部２２、可触部２４も、電力供給手段４と電気的に接続されている電力供給系統から電力供給を受けて動作する。 The gas heating unit 20 is a heating unit for heating an object to be heated (for example, a pot) placed on the gas by burning the gas. Although not shown, the gas heating unit 20 has a gas supply path for supplying gas, a burner for burning the supplied gas, and the like. The gas heating control unit 22 is a control unit that controls heating by the gas heating unit 20. The touchable portion 24 is a portion in the vicinity of the gas heating portion 20 that is exposed in a manner that the user can contact. The touchable portion 24 has an ignition unit 26 for igniting the gas and a flame detection unit 28 for detecting the combustion flame of the gas. As shown in FIG. 1, the gas heating unit 20, the gas heating control unit 22, and the touchable unit 24 also operate by receiving electric power from an electric power supply system electrically connected to the electric power supply means 4.

また、上述の電気加熱制御部１２と、ガス加熱制御部２２とは、それぞれ、フォトカプラを備える通信用回路を内蔵している。電気加熱制御部１２と、ガス加熱制御部２２とは、送信側の発光ダイオードに光を発光させ、受信側のフォトトランジスタを導通させることで信号伝達を行う。このように、上述の電気加熱制御部１２と、ガス加熱制御部２２とは、電気的に絶縁された状態で相互に通信可能に構成されている。 Further, the above-mentioned electric heating control unit 12 and the gas heating control unit 22 each have a built-in communication circuit including a photocoupler.

As described above, the above-mentioned electric heating control unit 12 and the gas heating control unit 22 are configured to be able to communicate with each other in an electrically insulated state.

図１に示されるように、本実施例の加熱調理器２は、加熱調理器２の電力供給系統中の位置Ｐ１、Ｐ２、Ｐ３のそれぞれに、基礎絶縁構造３０、４０、５０が設けられている。即ち、本実施例の加熱調理器２では、商用電源に接続される電力供給手段４と、外部に露出して利用者が接触可能な可触部２４と、の間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。 As shown in FIG. 1, in the cooking device 2 of the present embodiment, basic insulating structures 30, 40, and 50 are provided at positions P1, P2, and P3 in the power supply system of the cooking device 2, respectively. There is. That is, in the heating cooker 2 of the present embodiment, the power supply means 4 connected to the commercial power source and the touchable portion 24 exposed to the outside and contactable by the user are equivalent to double insulation. Insulation means that can exhibit insulation performance that exceeds the insulation performance have been constructed.

ここで、「二重絶縁」とは、基礎絶縁及び付加絶縁の両方で構成される絶縁のことを意味してもよい（ＪＩＳ規格参照）。二重絶縁の絶縁性能は、基礎絶縁の絶縁性能に比べて高い。「基礎絶縁」とは、感電に対する基礎的な保護を行うために、充電部（即ち、電気系統と接続されている部分）に施した絶縁のことを意味する（ＪＩＳ規格参照）。「付加絶縁」とは、基礎絶縁が破損した場合に感電に対する保護を行うために、基礎絶縁に追加された独立の絶縁のことを意味する（ＪＩＳ規格参照）。基礎絶縁構造３０、４０、５０は、例えば、一次側と二次側の配線を直接接続させない電源変換部（いわゆるトランス）を設ける構造である。また、他の例では、基礎絶縁構造３０、４０、５０は、一次側と二次側の配線をいずれの箇所においても所定距離以上離隔させる構造（いわゆる離隔による絶縁構造）であってもよい。 Here, "double insulation" may mean insulation composed of both basic insulation and additional insulation (see JIS standard). The insulation performance of double insulation is higher than that of basic insulation. "Basic insulation" means insulation applied to the charging part (that is, the part connected to the electrical system) in order to provide basic protection against electric shock (see JIS standard). "Additional insulation" means independent insulation added to the foundation insulation to protect against electric shock if the foundation insulation is damaged (see JIS standard). The basic insulation structures 30, 40, and 50 are, for example, a structure provided with a power conversion unit (so-called transformer) that does not directly connect the wiring on the primary side and the secondary side. Further, in another example, the basic insulating structures 30, 40, and 50 may have a structure that separates the wiring on the primary side and the secondary side by a predetermined distance or more at any position (so-called insulation structure by separation).

図１の例において基礎絶縁構造３０が設けられている位置Ｐ１は、電気加熱ユニット６内の電力供給系統のうち、電力供給手段４側の上流端部分と、電力を利用する電気加熱制御部１２と、の間の位置である。そのため、例えば、基礎絶縁構造３０は、高圧の交流電源である商用電源（例えばＡＣ２００Ｖ）を、電気加熱制御部１２で利用可能な低圧の直流電源（例えばＤＣ１２Ｖ）に変換するための降圧トランスである。ここで、「トランス」の語は、交流電源の変圧（降圧）を行う変圧部、変圧後の交流電源を整流して直流電源に変換する整流器、及び、直流電源を平滑する平滑コンデンサ、を含む装置のことを意味する場合がある。以下、本明細書において言及される各種の「トランス」についても同様とする。 In the example of FIG. 1, the position P1 where the basic insulating structure 30 is provided is the upstream end portion of the electric power supply system in the electric heating unit 6 on the side of the electric power supply means 4, and the electric heating control unit 12 that uses electric power. And the position between. Therefore, for example, the basic insulation structure 30 is a step-down transformer for converting a commercial power source (for example, AC200V), which is a high-voltage AC power source, into a low-voltage DC power source (for example, DC12V) that can be used by the electric heating control unit 12. .. Here, the term "transformer" includes a transformer unit that transforms (steps down) an AC power supply, a rectifier that rectifies an AC power supply after transformation and converts it into a DC power supply, and a smoothing capacitor that smoothes the DC power supply. Sometimes it means a device. The same shall apply hereinafter to the various "transs" referred to herein.

基礎絶縁構造４０が設けられている位置Ｐ２は、電気加熱ユニット６とガス加熱ユニット８とを電気的に接続するユニット間電力供給部である。そのため、例えば、基礎絶縁構造４０は、一次側と二次側との間で昇降圧を行わない絶縁トランスである。絶縁トランスも、上記の変圧部、整流器、及び、平滑コンデンサ、を含む。ただし、絶縁トランスは、その一次側において、直流電源を交流電源に変換する変換器をさらに含んでいる。これにより、絶縁トランスでは、変換部における直流電源から交流電源への変換、変圧部における交流電源の変圧（ただし昇降圧は行わない）、整流器における整流と直流電源への変換、及び、平滑コンデンサによる直流電源の平滑、が行われる。以下、本明細書で言及する絶縁トランスについても同様とする。 The position P2 where the basic insulating structure 40 is provided is an inter-unit power supply unit that electrically connects the electric heating unit 6 and the gas heating unit 8. Therefore, for example, the basic insulation structure 40 is an isolation transformer that does not perform buck-boost between the primary side and the secondary side. The isolation transformer also includes the above-mentioned transformer, rectifier, and smoothing capacitor. However, the isolation transformer further includes a converter that converts a DC power source into an AC power source on the primary side thereof. As a result, in the isolation transformer, the conversion from the DC power supply to the AC power supply in the conversion part, the transformation of the AC power supply in the transformer part (however, the buck-boost is not performed), the rectification in the rectifier and the conversion to the DC power supply, and the smoothing capacitor are used. Smoothing of the DC power supply is performed. Hereinafter, the same applies to the isolation transformer referred to in the present specification.

基礎絶縁構造５０が設けられている位置Ｐ３は、ガス加熱ユニット８内の電力供給系統のうち、ガス加熱ユニット８側の上流端部分と、電力を利用する各要素（即ち、ガス加熱部２０、ガス加熱制御部２２、及び、可触部２４）と、の間の位置である。例えば、基礎絶縁構造５０は、一次側と二次側との間で昇降圧を行わない絶縁トランスである。 The position P3 where the basic insulation structure 50 is provided is the upstream end portion of the power supply system in the gas heating unit 8 on the gas heating unit 8 side and each element that uses the power (that is, the gas heating unit 20, It is a position between the gas heating control unit 22 and the touchable unit 24). For example, the basic insulation structure 50 is an isolation transformer that does not perform buck-boost between the primary side and the secondary side.

以上、本実施例の加熱調理器２の構造を説明した。上記の通り、本実施例の加熱調理器２では、電力供給手段４と可触部２４との間に、合計３個の基礎絶縁構造３０、４０、５０が設けられている。即ち、本実施例の加熱調理器２では、電力供給手段４と可触部２４との間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。このような絶縁手段が備えられているため、本実施例によると、商用電源を電力供給源とする加熱調理器２において、利用者がガス加熱ユニット８の可触部２４に触れたとしても、感電を防止することができる。特に、本実施例では、電力供給手段４と可触部２４との間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されているため、電力供給手段４と可触部２４との間に基礎絶縁構造１個分のみの絶縁性能を発揮する絶縁手段が備えられている場合に比べて、高い絶縁性能を発揮可能である。即ち、利用者が感電する事態をより適切に防止することができる。 The structure of the cooking device 2 of this embodiment has been described above. As described above, in the cooking device 2 of the present embodiment, a total of three basic insulating structures 30, 40, and 50 are provided between the power supply means 4 and the touchable portion 24. That is, in the heating cooker 2 of the present embodiment, an insulating means capable of exhibiting an insulating performance exceeding the insulating performance equivalent to double insulation is constructed between the power supply means 4 and the touchable portion 24. Since such an insulating means is provided, according to the present embodiment, even if the user touches the touchable portion 24 of the gas heating unit 8 in the cooking cooker 2 using a commercial power source as a power supply source, the user touches the touchable portion 24. It is possible to prevent electric shock. In particular, in this embodiment, since an insulating means capable of exhibiting an insulating performance exceeding the insulating performance equivalent to double insulation is constructed between the power supply means 4 and the touchable portion 24, the power supply means 4 and the power supply means 4 are used. Higher insulation performance can be exhibited as compared with the case where an insulating means that exhibits insulation performance of only one basic insulating structure is provided between the touchable portion 24 and the touchable portion 24. That is, it is possible to more appropriately prevent the situation where the user receives an electric shock.

また、本実施例の加熱調理器２は、商用電源を電力供給源とする調理器であり、電気加熱ユニット６とガス加熱ユニット８を両方備えるハイブリッドタイプの調理器である。利用者は、加熱調理器２を利用して電気式加熱とガス式加熱を両方行うことができる。そして、利用者がガス加熱ユニット８の可触部２４に触れたとしても、感電する可能性は十分に抑制されている。利用者は、加熱調理器２を利用して、安全に電気式加熱とガス式加熱を行うことができる。 Further, the cooking device 2 of the present embodiment is a cooking device using a commercial power source as a power supply source, and is a hybrid type cooking device including both an electric heating unit 6 and a gas heating unit 8. The user can perform both electric heating and gas heating by using the cooking device 2. Even if the user touches the touchable portion 24 of the gas heating unit 8, the possibility of electric shock is sufficiently suppressed. The user can safely perform electric heating and gas heating by using the cooking device 2.

また、本実施例の加熱調理器２では、電気加熱ユニット６が電力供給手段４に電気的に接続されており、ガス加熱ユニット８が電気加熱ユニット６に電気的に接続されている。即ち、電力供給手段４、電気加熱ユニット６、ガス加熱ユニット８がこの順に直列に接続されている。そのため、仮に、ガス加熱ユニット８に不具合が発生する等して、ガス加熱ユニット８が動作できない状況が発生する場合であっても、電力供給手段４に電気的に接続されている電気加熱ユニット６を継続して動作させることができる。そのため、ガス加熱ユニット８が動作できない間に、加熱調理器２を用いた調理が全く行えない事態の発生を防止することができる。 Further, in the heating cooker 2 of the present embodiment, the electric heating unit 6 is electrically connected to the electric power supply means 4, and the gas heating unit 8 is electrically connected to the electric heating unit 6. That is, the power supply means 4, the electric heating unit 6, and the gas heating unit 8 are connected in series in this order. Therefore, even if a situation occurs in which the gas heating unit 8 cannot operate due to a malfunction in the gas heating unit 8, the electric heating unit 6 electrically connected to the power supply means 4 Can be operated continuously. Therefore, it is possible to prevent the occurrence of a situation in which cooking using the cooking device 2 cannot be performed at all while the gas heating unit 8 cannot operate.

（第２実施例）
図２に示される第２実施例の加熱調理器１０２について、第１実施例と異なる点を中心に説明する。本実施例の加熱調理器１０２も、第１実施例と同様に、電力供給手段４と、電気加熱ユニット６と、ガス加熱ユニット８と、を備える。電力供給手段４、電気加熱ユニット６、及び、ガス加熱ユニット８は、いずれも、第１実施例と同様の構成を有する。ただし、本実施例では、ガス加熱ユニット８は電力供給手段４に電気的に接続され、電気加熱ユニット６はガス加熱ユニット８に電気的に接続されている点が第１実施例とは異なる。即ち、本実施例では、電力供給手段４とガス加熱ユニット８と電気加熱ユニット６とがこの順で直列に接続されている。図２では、第１実施例の加熱調理器２（図１参照）と同じ構成を有する要素を、図１と同じ符号を用いて示している。本実施例では、第１実施例の加熱調理器２（図１参照）と同じ構成を有する要素についての詳しい説明は省略する。 (Second Example)
The cooking device 102 of the second embodiment shown in FIG. 2 will be described focusing on the differences from the first embodiment. The heating cooker 102 of this embodiment also includes a power supply means 4, an electric heating unit 6, and a gas heating unit 8 as in the first embodiment. The electric power supply means 4, the electric heating unit 6, and the gas heating unit 8 all have the same configuration as that of the first embodiment. However, in this embodiment, the gas heating unit 8 is electrically connected to the electric power supply means 4, and the electric heating unit 6 is electrically connected to the gas heating unit 8, which is different from the first embodiment. That is, in this embodiment, the power supply means 4, the gas heating unit 8, and the electric heating unit 6 are connected in series in this order. In FIG. 2, elements having the same configuration as the cooking utensil 2 (see FIG. 1) of the first embodiment are shown using the same reference numerals as those in FIG. In this embodiment, detailed description of the elements having the same configuration as the cooking cooker 2 (see FIG. 1) of the first embodiment will be omitted.

図２に示されるように、本実施例の加熱調理器１０２でも、商用電源に接続される電力供給手段４と、外部に露出して利用者が接触可能なガス加熱ユニット８の可触部２４と、の間における位置Ｐ１１、Ｐ１２、Ｐ１３のそれぞれに、基礎絶縁構造１３０、１４０、１５０が設けられている。即ち、本実施例の加熱調理器１０２でも、商用電源に接続される電力供給手段４と、外部に露出して利用者が接触可能な可触部２４と、の間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。 As shown in FIG. 2, also in the heating cooker 102 of the present embodiment, the touchable portion 24 of the power supply means 4 connected to the commercial power source and the gas heating unit 8 exposed to the outside and contactable by the user. Basic insulating structures 130, 140, and 150 are provided at positions P11, P12, and P13, respectively. That is, even in the heating cooker 102 of this embodiment, the power supply means 4 connected to the commercial power source and the touchable portion 24 exposed to the outside and contactable by the user are equivalent to double insulation. Insulation means that can exhibit insulation performance that exceeds the insulation performance have been constructed.

図２の例において基礎絶縁構造１３０が設けられている位置Ｐ１１は、電力供給手段４とガス加熱ユニット８とを電気的に接続する電力供給部である。そのため、例えば、基礎絶縁構造１３０は、高圧の交流電源である商用電源（例えばＡＣ２００Ｖ）を、ガス加熱部２０、ガス加熱制御部２２、及び、可触部２４で利用可能な比較的低圧の直流電源（例えばＤＣ１２Ｖ）に変換するための降圧トランスである。 In the example of FIG. 2, the position P11 where the basic insulating structure 130 is provided is a power supply unit that electrically connects the power supply means 4 and the gas heating unit 8. Therefore, for example, in the basic insulation structure 130, a commercial power source (for example, AC200V) which is a high voltage AC power source can be used as a relatively low voltage direct current which can be used in the gas heating unit 20, the gas heating control unit 22, and the touchable unit 24. It is a step-down transformer for converting to a power source (for example, DC12V).

基礎絶縁構造１４０が設けられている位置Ｐ１２は、ガス加熱ユニット８内の電力供給系統のうち、電力供給手段４側の上流端部分と、電力を利用する各要素（即ち、ガス加熱部２０、ガス加熱制御部２２、及び、可触部２４）と、の間の位置である。例えば、基礎絶縁構造１４０は、上記の降圧トランスであってもよいし、一次側と二次側との間で昇降圧を行わない絶縁トランスであってもよい。 The position P12 where the basic insulation structure 140 is provided is the upstream end portion of the power supply system in the gas heating unit 8 on the power supply means 4 side, and each element that uses the power (that is, the gas heating unit 20, It is a position between the gas heating control unit 22 and the touchable unit 24). For example, the basic insulation structure 140 may be the above-mentioned step-down transformer, or may be an isolation transformer that does not perform buck-boost between the primary side and the secondary side.

基礎絶縁構造１５０が設けられている位置Ｐ１３は、ガス加熱ユニット８内の電力供給系統のうち、位置Ｐ１２と、可触部２４と、の間の位置である。例えば、基礎絶縁構造１５０は、上記の絶縁トランスであってもよい。 The position P13 where the basic insulating structure 150 is provided is a position between the position P12 and the touchable portion 24 in the power supply system in the gas heating unit 8. For example, the basic insulation structure 150 may be the above-mentioned isolation transformer.

なお、図２の例では、電気加熱ユニット６内の電力供給系統のうち、ガス加熱ユニット８側の上流端部分と、電気加熱部１０との間の位置である位置Ｐ５０に、絶縁構造３００が設けられている。本実施例の絶縁構造３００は、ガス加熱ユニット８から供給される低圧の直流電源（例えばＤＣ１２Ｖ）を、電気加熱部１０で利用可能な高圧の交流電源（例えばＡＣ２００Ｖ）に昇圧させるための昇圧トランスである。絶縁構造３００として利用される昇圧トランスは、その一次側において直流電源を交流電源に変換する変換器と、交流電源の変圧（昇圧）を行う変圧部と、を備えるが、整流器と平滑コンデンサは備えない。そのため、絶縁構造（昇圧トランス）３００から電気加熱部１０には高圧の交流電源（例えばＡＣ２００Ｖ）が供給される。上記の通り、電気加熱部１０は、高圧の交流電源（この場合は商用電源（例えばＡＣ２００Ｖ））を、電気加熱部１０で利用可能な直流電源に変換するための変換部を内蔵している。電気加熱部１０は、内蔵された変換部によって変換された後の直流電源を利用して加熱を行う。 In the example of FIG. 2, in the power supply system in the electric heating unit 6, the insulating structure 300 is located at the position P50, which is the position between the upstream end portion on the gas heating unit 8 side and the electric heating unit 10. It is provided. The insulating structure 300 of this embodiment is a step-up transformer for boosting a low-voltage DC power supply (for example, DC12V) supplied from the gas heating unit 8 to a high-voltage AC power supply (for example, AC200V) that can be used by the electric heating unit 10. Is. The step-up transformer used as the insulation structure 300 includes a converter that converts a DC power source into an AC power source on the primary side thereof, and a transformer unit that transforms (boosts) the AC power source, but includes a rectifier and a smoothing capacitor. not. Therefore, a high-voltage AC power supply (for example, AC200V) is supplied from the insulating structure (step-up transformer) 300 to the electric heating unit 10. As described above, the electric heating unit 10 has a built-in conversion unit for converting a high-voltage AC power source (in this case, a commercial power source (for example, AC200V)) into a DC power source that can be used by the electric heating unit 10. The electric heating unit 10 heats using a DC power source after being converted by the built-in conversion unit.

以上、本実施例の加熱調理器１０２の構造を説明した。上記の通り、本実施例の加熱調理器１０２でも、電力供給手段４と可触部２４との間に、合計３個の基礎絶縁構造１３０、１４０、１５０が設けられている。即ち、本実施例の加熱調理器１０２でも、電力供給手段４と可触部２４との間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。従って、本実施例でも、利用者がガス加熱ユニット８の可触部２４に触れたとしても、感電することを防止することができる。 The structure of the cooking device 102 of this embodiment has been described above. As described above, also in the cooking device 102 of this embodiment, a total of three basic insulating structures 130, 140, and 150 are provided between the power supply means 4 and the touchable portion 24. That is, even in the heating cooker 102 of this embodiment, an insulating means capable of exhibiting an insulating performance exceeding the insulating performance equivalent to double insulation is constructed between the power supply means 4 and the touchable portion 24. Therefore, even in this embodiment, even if the user touches the touchable portion 24 of the gas heating unit 8, it is possible to prevent an electric shock.

また、本実施例の加熱調理器１０２では、電力供給手段４、ガス加熱ユニット８、電気加熱ユニット６がこの順に直列に接続されている。そのため、仮に、電気加熱ユニット６に不具合が発生する等して、電気加熱ユニット６が動作できない状況が発生する場合であっても、電力供給手段４に電気的に接続されているガス加熱ユニット８を継続して動作させることができる。そのため、電気加熱ユニット６が動作できない間に、加熱調理器１０２を用いた調理が全く行えない事態の発生を防止することができる。 Further, in the cooking apparatus 102 of this embodiment, the electric power supply means 4, the gas heating unit 8, and the electric heating unit 6 are connected in series in this order. Therefore, even if a situation occurs in which the electric heating unit 6 cannot operate due to a problem in the electric heating unit 6, the gas heating unit 8 electrically connected to the power supply means 4 is connected. Can be operated continuously. Therefore, it is possible to prevent the occurrence of a situation in which cooking using the cooking device 102 cannot be performed at all while the electric heating unit 6 cannot operate.

（第３実施例）
図３に示される第３実施例の加熱調理器２０２について、第１実施例と異なる点を中心に説明する。本実施例の加熱調理器２０２も、第１実施例と同様に、電力供給手段４と、電気加熱ユニット６と、ガス加熱ユニット８と、を備える。電力供給手段４、電気加熱ユニット６、及び、ガス加熱ユニット８は、いずれも、第１実施例と同様の構成を有する。ただし、本実施例では、電気加熱ユニット６とガス加熱ユニット８が、それぞれ、電力供給手段４に電気的に接続されている点が第１実施例とは異なる。即ち、本実施例では、電力供給手段４に対して、電気加熱ユニット６とガス加熱ユニット８が互いに並列に接続されている。図３でも、第１実施例の加熱調理器２（図１参照）と同じ構成を有する要素を、図１と同じ符号を用いて示している。本実施例では、第１実施例の加熱調理器２（図１参照）と同じ構成を有する要素についての詳しい説明は省略する。 (Third Example)
The cooking device 202 of the third embodiment shown in FIG. 3 will be described focusing on the differences from the first embodiment. The heating cooker 202 of this embodiment also includes a power supply means 4, an electric heating unit 6, and a gas heating unit 8 as in the first embodiment. The electric power supply means 4, the electric heating unit 6, and the gas heating unit 8 all have the same configuration as that of the first embodiment. However, this embodiment is different from the first embodiment in that the electric heating unit 6 and the gas heating unit 8 are electrically connected to the electric power supply means 4, respectively. That is, in this embodiment, the electric heating unit 6 and the gas heating unit 8 are connected in parallel to the electric power supply means 4. Also in FIG. 3, elements having the same configuration as the cooking utensil 2 (see FIG. 1) of the first embodiment are shown using the same reference numerals as those in FIG. In this embodiment, detailed description of the elements having the same configuration as the cooking cooker 2 (see FIG. 1) of the first embodiment will be omitted.

図３に示されるように、本実施例の加熱調理器２０２でも、商用電源に接続される電力供給手段４と、外部に露出して利用者が接触可能なガス加熱ユニット８の可触部２４と、の間における位置Ｐ２１、Ｐ２２、Ｐ２３のそれぞれに、基礎絶縁構造２３０、２４０、２５０が設けられている。即ち、本実施例の加熱調理器２０２でも、商用電源に接続される電力供給手段４と、外部に露出して利用者が接触可能な可触部２４と、の間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。 As shown in FIG. 3, also in the heating cooker 202 of the present embodiment, the touchable portion 24 of the power supply means 4 connected to the commercial power source and the gas heating unit 8 exposed to the outside and accessible to the user. Basic insulating structures 230, 240, and 250 are provided at positions P21, P22, and P23, respectively. That is, even in the heating cooker 202 of the present embodiment, the power supply means 4 connected to the commercial power source and the touchable portion 24 exposed to the outside and contactable by the user are equivalent to double insulation. Insulation means that can exhibit insulation performance that exceeds the insulation performance have been constructed.

図３の例において基礎絶縁構造２３０が設けられている位置Ｐ２１は、電力供給手段４とガス加熱ユニット８とを電気的に接続する電力供給部である。そのため、例えば、基礎絶縁構造２３０は降圧トランスである。 In the example of FIG. 3, the position P21 where the basic insulating structure 230 is provided is a power supply unit that electrically connects the power supply means 4 and the gas heating unit 8. Therefore, for example, the basic insulation structure 230 is a step-down transformer.

基礎絶縁構造２４０が設けられている位置Ｐ２２は、ガス加熱ユニット８内の電力供給系統のうち、電力供給手段４側の上流端部分と、電力を利用する各要素（即ち、ガス加熱部２０、ガス加熱制御部２２、及び、可触部２４）と、の間の位置である。例えば、基礎絶縁構造２４０は、降圧トランスであってもよいし、絶縁トランスであってもよい。 The position P22 where the basic insulation structure 240 is provided is the upstream end portion of the power supply system in the gas heating unit 8 on the power supply means 4 side, and each element that uses the power (that is, the gas heating unit 20, It is a position between the gas heating control unit 22 and the touchable unit 24). For example, the basic insulation structure 240 may be a step-down transformer or an isolation transformer.

基礎絶縁構造２５０が設けられている位置Ｐ２３は、ガス加熱ユニット８内の電力供給系統のうち、位置Ｐ２２と、可触部２４と、の間の位置である。例えば、基礎絶縁構造２５０は、絶縁トランスであってもよい。 The position P23 where the basic insulating structure 250 is provided is a position between the position P22 and the touchable portion 24 in the power supply system in the gas heating unit 8. For example, the basic insulation structure 250 may be an isolation transformer.

なお、図３の例では、電気加熱ユニット６内の電力供給系統のうち、電力供給手段４側の上流端部分と、電気加熱制御部１２との間の位置である位置Ｐ６０にも、絶縁構造４００が設けられている。本実施例の絶縁構造４００は、電気加熱ユニット６のための絶縁構造であって、基礎絶縁構造と強化絶縁構造のどちらであってもよい。また、図３に示すように、本実施例でも、電気加熱部１０は、電力供給手段４に直接接続されている。 In the example of FIG. 3, in the power supply system in the electric heating unit 6, the position P60, which is the position between the upstream end portion on the power supply means 4 side and the electric heating control unit 12, also has an insulating structure. 400 is provided. The insulating structure 400 of this embodiment is an insulating structure for the electric heating unit 6, and may be either a basic insulating structure or a reinforced insulating structure. Further, as shown in FIG. 3, in this embodiment as well, the electric heating unit 10 is directly connected to the power supply means 4.

以上、本実施例の加熱調理器２０２の構造を説明した。上記の通り、本実施例の加熱調理器２０２でも、電力供給手段４と可触部２４との間に、合計３個の基礎絶縁構造２３０、２４０、２５０が設けられている。即ち、本実施例の加熱調理器２０２でも、電力供給手段４と可触部２４との間において、二重絶縁相当の絶縁性能を上回る絶縁性能を発揮可能な絶縁手段が構築されている。従って、本実施例でも、利用者がガス加熱ユニット８の可触部２４に触れたとしても、感電することを防止することができる。 The structure of the cooking device 202 of this embodiment has been described above. As described above, also in the cooking device 202 of the present embodiment, a total of three basic insulating structures 230, 240, and 250 are provided between the power supply means 4 and the touchable portion 24. That is, also in the heating cooker 202 of this embodiment, an insulating means capable of exhibiting an insulating performance exceeding the insulating performance equivalent to double insulation is constructed between the power supply means 4 and the touchable portion 24. Therefore, even in this embodiment, even if the user touches the touchable portion 24 of the gas heating unit 8, it is possible to prevent an electric shock.

また、本実施例の加熱調理器２０２では、電気加熱ユニット６とガス加熱ユニット８が、それぞれ、電力供給手段４に電気的に接続されている。即ち、電力供給手段４に対して、電気加熱ユニット６とガス加熱ユニット８が互いに並列に接続されている。そのため、仮に、電気加熱ユニット６とガス加熱ユニット８のうちの一方に不具合が発生する等して、一方の加熱ユニットが動作できない状況が発生する場合であっても、電力供給手段４に電気的に接続されている他方の加熱ユニットを継続して動作させることができる。そのため、一方の加熱ユニットが動作できない間に、加熱調理器２０２を用いた調理が全く行えない事態の発生を防止することができる。 Further, in the cooking device 202 of the present embodiment, the electric heating unit 6 and the gas heating unit 8 are electrically connected to the electric power supply means 4, respectively. That is, the electric heating unit 6 and the gas heating unit 8 are connected in parallel to the electric power supply means 4. Therefore, even if a problem occurs in one of the electric heating unit 6 and the gas heating unit 8 and one of the heating units cannot operate, the power supply means 4 is electrically operated. The other heating unit connected to can be continuously operated. Therefore, it is possible to prevent the occurrence of a situation in which cooking using the cooking device 202 cannot be performed at all while one of the heating units cannot operate.
