Problems solved by technology

The disadvantage of using this method is that it needs more other matching hardware parts, the cost is high, and the structure and processing are complicated. Secondly, because the temperature sensing part is set in the middle of the heating plate, the temperature detection is easily affected by the temperature of the heating plate, making the detection Inaccurate; again, due to the hole in the middle, the contact area between the bottom of the pot and the heating plate is reduced, thus affecting the use effect of the electric heating pot

Embodiment Construction

[0036] Such as Figure 1-Figure 4 Shown is the schematic diagram of the contact surface between the bottom of the pot liner and the heating plate in the prior art when it is cold, at 100°C, 200°C, and 300°C. The distance between them is 0, and the distance between them is 0.1mm at 100°C, 0.5mm at 200°C, and 1mm at 300°C. It can be seen that when the composite pot bottom structure is not used, its Heating will be uneven.

[0037] Such as Figure 5 , Image 6, shown in Fig. 7, Fig. 8, adopted the electric pressure cooker at the bottom of single-layer stainless steel pot liner of the present invention to comprise pot cover (not shown in the figure), shell, pot liner 1, inner cover 2, inner cover chassis 3 and setting The heating plate 4 and the control circuit on the inner cover chassis, the pot liner 1 is a stainless steel single-layer structure, and the bottom of the heating plate is provided with three or more supporting feet, and the supporting legs are equidistantly arrang...

Abstract

The present invention relates to a kind of electric pressure cooker and electric rice cooker. It includes outer shell, pot cover, inner pot, heating disk and temperature detection and control device of electric heating pot. The inner pot is placed in the upper portion of heating disk, and said inner pot is a stainless steel single-layer structure. The temperature detection and control device of invented electroheating pot is formed from heat sensing element and control circuit of electroheating pot, and said heat sensing element is fixed on the heating disk.

Description

technical field [0001] The invention relates to the technical field of electric heating pots, and more specifically relates to the improvement technology of electric heating pots such as electric pressure cookers and electric rice cookers. Background technique [0002] Traditional electric pressure cookers and electric rice cookers are generally equipped with a pot liner on the upper part of the electric heating plate. The pot liner is generally made of aluminum material, and the inner surface of the pot liner is coated with non-stick materials. Since non-stick coatings such as Teflon Dragon can be decomposed above 260°C to produce carcinogenic toxic substances, which is not conducive to people's health. [0003] In order to avoid the defects of the aluminum pot liner, a stainless steel pot liner has appeared since 2000. However, the heating plate for heating the liner adopts the technology of casting the heating element into the aluminum plate. Due to the different thermal ...
