Electric pressure cooker for quick cooking

Abstract

The invention belongs to the field of kitchen appliances, and relates to an electric pressure cooker, in particular to an electric pressure cooker for quick cooking. The electric pressure cooker comprises a cooker body; an upper cover assembly is arranged on the cooker body; the interior of the cooker body is sleeved with an inner pot; a main control circuit is arranged in the cooker body; the electric pressure cooker is characterized in that a carbon fiber heating device is arranged on the outer wall of the inner pot; the carbon fiber heating device is formed by combining flat bundles of carbon fibers and glass fibers according to a predetermined proportion; an electrical connection terminal is arranged at the end of the carbon fiber heating device; the carbon fiber heating device is fixed on the outer wall of the inner pot by means of a soft insulator; heat-conducting glue or heat-conducting grease is arranged between the carbon fiber heating device and the outer wall of the inner pot; an electric contact convex column matched with the electrical connection terminal is arranged in the cooker body; the electric contact convex column is electrically connected with the main controlcircuit. The electric pressure cooker for quick cooking is simple in structure, easy to connect, rapid in heating speed, uniform in heat transfer and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the field of kitchen appliances, and relates to an electric pressure cooker, in particular to an electric pressure cooker for fast cooking. Background technique [0002] At present, the kitchen electric cooking utensils on the market generally have the following heating methods: [0003] One is to heat the bottom of the pot body through the electric heating plate. The current electric cooker generally uses the heat transfer method of the electric heating plate and the pot body. This method of heating is convenient for processing and assembly, but the thermal efficiency is low. If the surface curvature of the electric heating plate or the inner pot If the curvature of the bottom is deformed, it will cause abnormal heating. [0004] The second is to achieve heating by directly welding or crimping and casting the heating tube at the bottom of the pot body. Although this method can effectively improve the thermal efficiency, the h...

Problems solved by technology

[0003] One is to heat the bottom of the pot body through the electric heating plate. The current electric cooker generally uses the heat transfer method of the electric heating plate and the pot body. This method of heating is convenient for processing and assembly, but the thermal efficiency is low. If the surface curvature of the electric heating plate or the inner pot If the curvature of the bottom is deformed, it will cause abnormal heating

[0004] The second is to achieve heating by directly welding or crimping and casting the heating tube at the bottom of the pot body. Although this method can effectively improve the thermal efficiency, the heat generated is concentrated at the electric heating tube, and the heat around the electric heating tube is still uneven. The temperature difference between the hot end and the cold end is large, which may easily lead to burnt phenomenon during cooking

[0005] The third is through the electromagnetic heating method, which can effectively improve the thermal efficiency, and the heat transfer is relatively uniform, but it has high requirements on the material of the pot body, and the cost of the pot body and electric control is also very high, accompanied by the generation of eddy current The coil also generates a lot of heat, and it is necessary to add related heat dissipation equipment to dissipate heat, and at the same time take away part of the electric energy, resulting in a certain amount of electric energy loss

[0006] Fourth, by directly printing the electric heater on the bottom of the pot body or printing the electric heating film on the substrate, and then welding it on the bottom of the pot body, the electric heating film is heated relative to the electric heating tube, and the heat transfer at the bottom is relatively uniform, and there will b
