Description
Technical Field
The utility model relates to an electromagnetism cooking utensil technical field especially relates to a quick temperature sensing panel and electromagnetism cooking utensil with temperature sensing device.
Background
Since the electromagnetic heating technology is applied to the cooking industry, temperature control is always a big problem, and the main electromagnetic oven has the following two structures:
the first structure is as follows: the cooker, the microcrystal panel (about 4 mm) and the sensor component (comprising a shell, an insulating layer and a sensor are sequentially arranged from top to bottom, and the position of the sensor is arranged at the center of the coil disc). Because the micrite panel is flat structure, and the sensor subassembly hugs closely in the bottom surface of micrite panel, the characteristics of this kind of structure are that temperature sensor is too far away from between the pan, and the temperature of pan needs to be conducted the micrite panel of 4mm thick earlier, makes the micrite panel generate heat, then by micrite panel with heat conduction to sensor, consequently has the slow problem of heat conduction. In normal household cooking, the heating temperature generally required does not exceed 280 ℃, but because the temperature cannot be rapidly sensed, a pot which is thin may be burnt red, but the temperature cannot be sensed by the sensor. The results from this phenomenon are as follows: 1. potential safety hazards, severe lagging temperature sensing, can cause the oil to reach the ignition point when the amount of oil is small, causing a fire; 2. too high oil temperature produces large amounts of aromatic hydrocarbons, which are severely carcinogenic. 3. The Chinese dishes are cooked and have poor taste.
The second structure is as follows: the hole is formed in the center position of the microcrystalline glass relative to the coil panel, the temperature sensor component is in direct contact with the cooker, and the sensor component comprises a shell, an insulating layer and a sensor. The shell of the sensor is generally made of metal, and when a pot is placed on the top of the sensor, the metal shell can generate heat in an alternating magnetic field (all metals can generate heat under the pot of the induction cooker, and the closer the metal shell is to the pot, the faster the metal shell generates heat), so that the temperature sensing of the sensor is inaccurate; in addition, according to the requirements of safety regulations, an insulating layer is required below the shell of the sensor, and engineering plastics which can resist the temperature of about 350 ℃ are generally adopted, so that the thermal conductivity is poor. The biggest defect of the structure is that the shell can generate heat to continuously accumulate heat, and in addition, the temperature of the cookware cannot be really judged due to the heating of the shell, so that the breakthrough of the temperature sensing technology cannot be realized. At the same time, additional costs are paid for waterproofing and anti-aging.
The above two structures also have the following common disadvantages: in order to ensure that the sensor does not leak electricity, the outer shell is required to be arranged outside the sensor, so that the size of the sensor assembly is large, a special assembly position needs to be designed on the coil panel, and the heat generation efficiency of the coil panel is considered, so that the sensor assembly is usually required to be designed in the center of the coil panel. The heat of electromagnetic heating is mainly concentrated on a circular ring with the diameter of about 90mm, so that the sensor is too far away from the high-temperature area to accurately feed back the temperature. Almost all induction cooker manufacturers need to use their own induction cooker to perform different pot heating experiments, record temperature change curves, compare the temperature change curves with the recorded curves when users use the induction cooker, and evaluate the heating condition of the pots. However, in the actual use process, the quality change of the pan, the type change of the pan and the change of food materials are unpredictable, so that the induction cooker cannot become a mainstream cooking tool and is mainly used for boiling water, making hot pots, cooking porridge and the like. In the aspect of panel use, because accurate temperature sensing cannot be achieved, microcrystalline glass with higher temperature resistance is needed to reduce the risk of excessive heat generation, and therefore the panel cost of the induction cooker is high.
