Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] like figure 1 As shown, an electric heating cooker is a soup pot used for cooking soup, including an inner pot 1, a heater 2 for heating the inner pot 1, and an inner pot temperature detector for detecting the temperature of the inner pot 1 10. The heater temperature detector 20 and the controller 3 that detect the temperature of the heater 2, the inner pot temperature detector 10, the heater temperature detector 20 and the heater 2 are respectively connected to the controller 3 with electrical signals . The inner pot 1 is placed on the upper surface of the heater 2, and the heat emitted by the heater 2 is mainly transferred to the inner pot 1 through direct conduction. The controller 3 controls the on and off of the heater 2 or the magnitude of the heating power through a thyristor circuit.

Abstract

The invention discloses a temperature control method of electric heating kitchenware, which comprises the following steps of: starting a heater and coming to a heating temperature rise period, when the temperature of an inner pot reaches first upper limit temperature value A1 of the inner pot or the temperature of the heater reaches first upper limit temperature value B1 of the heater, driving the heater by a controller to reduce heating power or stopping heating, and making the heater come to a constant temperature heating period; when the temperature of the inner pot is reduced to constant temperature target temperature T1 and the temperature of the heater is lower than second upper limit temperature value B2 of the heater, driving the heater by the controller to increase heating power; and when the temperature of the inner pot is increased to constant temperature target temperature T1 or the temperature of the heater reaches second upper limit temperature value B2, driving the heater by the controller to reduce heating power or stopping heating. In this way, the temperature control method not only realizes simple control structure and smaller consumed electric power, but also makes food cooking temperature T0 remain unchanged substantially. Due to the above characteristics, the temperature control method can be applied to the electric heating kitchenware such as general electric rice cooker, soup pot, oven and the like.

Description

technical field [0001] The invention relates to an electric heating cooker for cooking, in particular to a temperature control method for constant temperature cooking of the electric heating cooker. Background technique [0002] In the prior art, when it comes to electric cooking utensils such as electric rice cooker, electric pressure cooker, etc., the temperature sensing device is usually used to directly detect the bottom temperature of the inner pot. When the detected bottom temperature of the inner pot is higher than the set value, the temperature sensing device will act Cut off the power to the heater directly or through the controller of the electric cooker. The obvious defect of the electric cooker with this structure is that it only controls the temperature of the inner pot body itself, but cannot control the temperature of the heater. During the cooking process, the temperature of the inner pot body varies greatly, usually at ±10°C, Thereby the range of temperatur...
