Panel structure of electromagnetic heating device

Abstract

The invention relates to a panel structure of an electromagnetic heating device, comprising a concave arc panel and an electromagnetic coil arranged at the outer side of the panel; the panel comprises a bottom wall part and a side wall part surrounding the bottom wall part and forming the concave arc panel; the center of the bottom wall part is provided with a vent hole and a temperature sensor; and the inner side wall of the panel is symmetrically provided with a cookware positioning boss. More than three radial convex bars are uniformly arranged along the outer side wall of the panel, and the electromagnetic coil is tightly clung and fixedly connected with the top parts of the radial convex bars; a first electromagnetic coil is correspondingly arranged at the bottom wall part; a second electromagnetic coil is correspondingly arranged at the side wall part; and the second coil is arc-shaped and is matched with the outer side wall of the side wall part. A ring-shaped bottom groove is arranged at the inner side of the panel and positioned at the joint of the bottom wall part and the side wall part; and more than one vent hole which penetrates through the panel is arranged in the bottom groove. Due to the advantages, the panel structure can be widely applied in electrical appliances using the electromagnetic heating device, in particularly to an electromagnetic oven product used for cooking dishes.

Description

technical field [0001] The invention relates to an electromagnetic heating appliance, in particular to a panel structure with a curved panel for the electromagnetic heating appliance. Background technique [0002] The arc-shaped panel structure of the existing electromagnetic heating appliance is more typically disclosed on November 10, 1999, and the name is called the ZL98241610.5 utility model patent of "an electromagnetic cooker coil that is especially suitable for a frying pan". This patent discloses that a coil for passing current is provided inside the induction cooker, and an arc-shaped ceramic panel is arranged above the coil, and an arc-shaped pot can be placed on the top of the panel; the feature is that the coil is matched with the pot The arc shape extends from the inside to the outside to form a concave arc surface, so that each part of the coil maintains the same distance from the upper ceramic panel and the arc-shaped pot. The coil of the utility model can co...

AI Technical Summary

Problems solved by technology

Through the analysis of the above technical solution, it can be found that the technical solution does not consider the thermal influence of the high temperature of the cooking pot on the curved ceramic panel and the heat dissipation of the panel itself, nor does it consider the temperature control of the upper pot, resulting in the use of The induction cooker manufactured by this technology not only cannot work continuously for a relatively long time, but also the heating area of ​​the pot is too small, the taste of cooking is very poor, and the cooked objects in the pot cannot be effectively controlled, resulting in burning problems; Secondly, we have to use expensive high-temperature-resistant panels such as microcrystalline panels, but at present, the domestic production of concave arc-shaped microcrystalline panels has not been effectively solved. Not only is the supply very small, but all rely on imports; Shaped panels, due to the small thermal expansion coefficient of ceramic materials, high temperature is easy to crack

Therefore, after the disclosure of the above-mentioned technical invention, it has not been effectively applied so far.
