  However, in the configuration of the conventional example, despite the fact that high heat power is necessary for the stir-fried foods, etc. The user feels bothersome and power consumption when operating is increased, so a key to release the thermal power squeezing when there is no pan is provided, so that the thermal power squeezing can be released when fried In the cooking of curry, etc., in order to stir meat and vegetables first, add water and simmer. When you lift the pan and move it, there is a risk that the flame may ignite the combustibles such as clothes. wastefully Expenditure when the pan is lifted after it has been spent or if it is determined to be water cooking, and the fire extinguishes when it exceeds the burn-out temperature, or when the pan is returned just before the burn-out temperature is reached Due to the above, there was a problem that the temperature became higher than the burning temperature and the fire was extinguished.

  The present invention solves the above-mentioned conventional problem, and when it is determined that the cooking mode is a specific cooking mode such as cooking for water based on a signal from the temperature detection means, the thermal power restriction release setting means sets the thermal power restriction release setting. Even if it has been detected, when it is judged that there is no pan from the signal from the pan presence / absence detection means, a signal for reducing the combustion amount is output to the combustion amount variable means, and the release of the thermal power throttling is canceled by display or sound It is an object of the present invention to provide a gas cooker that is configured not to extinguish unnecessarily when the pan is lifted and when the pan is returned.

To cancel Even if it is determined, if it is determined by the signal from the pan presence / absence detection means that the pan is not placed, the setting of the thermal power throttling release setting means is ignored and the combustion amount is reduced to the combustion amount variable means A signal is output.

  According to the above invention, first, since the heating power is varied according to the pan mounting state by the pan presence / absence detection means, when there is no pan, the heating power can be reduced and combustion can be performed. It is possible to avoid a situation in which clothes such as cuffs are ignited during movement. In addition, when the pan is moved frequently depending on the type of cooking, it is possible to prevent the thermal power squeezing operation at the time of no pan detection with the thermal power squeeze release setting means, which improves usability. is there. Furthermore, even when the thermal power throttling operation is canceled by the thermal power throttling cancellation setting unit, when it is determined that the cooking mode is a specific cooking mode by the signal from the temperature detection unit, for example, when it is determined that the cooking is a water product Thereafter, the setting of the thermal throttling release setting means is ignored, and a signal for restricting the combustion amount is output to the combustion amount variable means, so when the pan is lifted and moved, it is applied to combustibles such as clothes. In addition to preventing the fire from being burned, energy consumption is reduced when cooking is finished and the forgetting to put out the fire while the pan is moved, and unnecessary fire extinguishing can be prevented even when the pan is lifted or returned.

  When the gas cooker according to the present invention determines that the cooking mode is a specific cooking mode as in the case of aquatic cooking based on a signal from the temperature detection means, it is a case where the thermal power restriction release setting means has been set to release the thermal power restriction. However, when it is determined that there is no pan based on the signal from the pan presence / absence detection means, a signal for reducing the combustion amount is output to the combustion amount variable means, and the user is informed that the release of the thermal power throttling has been canceled by display or sound.
