Microwave oven capable of rapidly heating feeble microwave absorbing material

Abstract

The invention relates to a microwave oven capable of rapidly heating a feeble microwave absorbing material. The microwave oven is capable of rapidly heating the feeble microwave absorbing material, and the microwave oven has a certain effect for a material which has difficulty in absorbing microwaves. The microwave oven is characterized in that an auxiliary electric field produces a circuit, the circuit is controlled by virtue of the auxiliary electric field, and the circuit is composed of positive and negative metal battery plates; the electric supply controls the circuit through a voltage transformation circuit, a rectification filter and the auxiliary electric field, and the positive and negative metal battery plates transmit an auxiliary electric field in a microwave cavity; the auxiliary electric field causes multiple polarization of the heated feeble microwave absorbing material, the electric dipole moment of molecules is further increased, and the polarized feeble microwave absorbing material can produce greater combined electric field force and torque under the irradiation of the microwave field, so that the friction, extrusion and collision among the molecules are more intense, the microwave energy can be rapidly absorbed so as to be converted into self heat energy, and the rapid heating effect can be achieved.

Description

technical field [0001] The invention relates to a microwave oven for quickly heating weak wave-absorbing substances. Specifically, the microwave oven can quickly heat some weak wave-absorbing substances, and even works on heating difficult wave-absorbing substances, and belongs to the field of microwave heating. Background technique [0002] Microwave is a new technology that has emerged in recent decades. Compared with traditional heating, microwave has the advantages of internal heating, fast heating, clean and hygienic, easy automatic control, and energy saving. However, microwave heating is selective to materials, it is difficult to heat substances composed of weak polar molecules (weak absorbing substances), and it cannot heat substances composed of non-polar molecules (difficult to absorb waves), so it is difficult to achieve large-scale applications and limits development of the microwave industry. [0003] In industry, auxiliary heating is generally used for weak ab...

AI Technical Summary

Problems solved by technology

These auxiliary heating methods have disadvantages: 1. The heating process is relatively complicated; 2. The energy loss is large, and it is necessary to do useless work to heat the strong absorbing material; 3. The weak absorbing material needs to be mixed with the strong absorbing material during the heating process. New impurities may be generated in weak absorbing substances
