Heating panel for cooking tool and frying dish used by heating panel

Abstract

The invention provides a heating panel for a cooking tool and a frying dish used by the heating panel. A first insulation layer is covered on the panel bottom face of the heating panel. A thick-film heating circuit is arranged between the panel bottom face and the first insulation layer. The thick-film heating circuit is connected with a control circuit. A thick-film temperature detecting circuit is further arranged on the heating panel. The thick-film temperature detecting circuit is arranged along the arranging route of the thick-film heating circuit. Due to the fact that the thick-film temperature detecting circuit is arranged along the arranging route of the thick-film heating circuit, the thick-film temperature detecting circuit can detect temperatures at all positions of the thick-film heating circuit, boundedness and hysteresis of temperature detecting are avoided, so that the control circuit can obtain accurate temperature information at any moment, accordingly accuracy and timeliness of frying dish temperature control are improved, a control seat which can be connected in an insertion-extraction mode is additionally arranged on the frying dish, when the frying dish is washed, the control seat can be pulled out first, so that the problem that the control circuit is wetted is avoided, and convenience is brought to a user.

Description

technical field [0001] The invention relates to a heating panel applied to a cooking tool, and a frying pan using the heating panel. Background technique [0002] Traditional heating panels use single-point temperature sensing, which is mainly a Hall temperature sensor. The Hall temperature sensor is usually set near the electric heating tube to directly detect the temperature of the electric heating tube for control. When the electric heating tube is heating, since the temperature of the electric heating tube is the same everywhere, the temperature sensor only needs to be set near a certain point of the electric heating tube, and the temperature of the electric heating tube can be inferred by measuring the temperature value of the point of the electric heating tube. [0003] Although the temperature of the electric heating tube does not change much when heating, when the surface of the heating panel touches liquid or food, the temperature will drop in a straight line at an ...

Problems solved by technology

So when a specific point or a specific area on the surface of the heating panel is in contact with liquid or food alone, the temperature measured by the temperature sensor elsewhere is not equivalent to the temperature at that point; or, the distance between a specific point or a specific area and the temperature sensor When it is far away, the temperature sensor cannot directly sense the temperature change of cooking, so the cooking process of the existing heating panel is prone to misunderstanding of temperature control, which makes it difficult to control the temperature; and because the frying pan has high requirements for temperature control, the above The phenomenon will seriously affect the cooking quality of the frying pan, for this reason, a kind of technical solution that can solve the above-mentioned problems is urgently needed
