Embodiment Construction

[0062] figure 1 It is a schematic diagram of an embodiment of a non-contact heating intensity measurement method of the present invention. This measurement method is also a kind of radiant heat measurement method, and the measured value is an instantaneous (real-time) value. In the figure, 1 is the heat source, 2 is the heat radiation emitted by the heat source, 3 is the Fresnel lens, 4 is the thermopile detection device, 5 is the detection signal, 6 is the control device of the cooking appliance, and R is the distance between the detection device and the heat source. space distance.

[0063] The sensing surface of the thermopile 4 is aimed at the flame to be measured through the Fresnel lens 3, so as to measure the radiant heat of the current flame. The output signal of the thermopile sensor is a voltage signal, which is related to the current thermal radiation power Φ R (unit Watt) is proportional to. By the formula Φ=K×Φ R The current firepower intensity (unit Watt) ca...

Abstract

The invention discloses a brand new control method used for controlling cooking heat. The method realizes cooking heat control by measuring heating intensity of a cooking heat source. The invention also discloses a cooking method and a cooking system by using the control method. Compared with the prior art, the invention regulates relevant factors of the cooking heat according to the heating intensity and change situations of the heat source, thereby being capable of controlling the cooking heat more directly, duly and accurately.

Description

technical field [0001] The present invention relates to a heat control method and device, more specifically, the present invention relates to a cooking heat control method based on data measured by a heating intensity measuring device and a cooking utensil equipped with a heating intensity measuring device. Background technique [0002] Cooking heat is determined by two factors: "fire" and "hou". "Huo" is the size of firepower, and "waiting" is the length of time. Among them, "fire" is a more basic factor, because the length of heating time depends on the size of the firepower. The so-called firepower is actually the heating intensity of the heating source. In the actual cooking process, the heating intensity of heating heat sources such as flames, resistance heat sources, infrared radiation sources, electromagnetic heat sources, etc. will change and need to be adjusted in most cases. For example, the calorific value of the gas source is inconsistent or unstable. Although...
