Embodiment Construction

[0026] The following description and the accompanying drawings sufficiently illustrate specific embodiments herein to enable those skilled in the art to practice them. Portions and features of some embodiments may be included in or substituted for those of other embodiments. The scope of the embodiments herein includes the full scope of the claims, and all available equivalents of the claims. Herein, the terms "first", "second", etc. are only used to distinguish one element from another element without requiring or implying any actual relationship or order between these elements. In fact the first element can also be called the second element and vice versa. Furthermore, the terms "comprising", "comprising" or any other variation thereof are intended to cover a non-exclusive inclusion such that a structure, means or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed elements, or also elements inherent in th...

Abstract

The invention relates to a power output circuit. The power output circuit comprises two or more circulators connected in a cascaded manner, and the two or more circulators comprise a primary circulator and a final circulator, wherein the primary circulator is configured to send a power signal from a heated environment to a next-stage circulator, and the final-stage circulator is configured to sendthe power signal to the heated environment. According to the embodiment of the invention, through the cascaded connection structure of two or more circulators, the energy reuse of the power signal isrealized, the energy consumption is reduced, and the energy utilization rate is improved.

Description

technical field [0001] The present application relates to the field of microwave technology, for example, to power output circuits and microwave heating equipment. Background technique [0002] At present, with the development of semiconductor microwave ovens, increasing the power of microwave ovens is the key to increasing the heating speed of microwave ovens. During the use of the microwave oven, due to the difference in the impedance of the heated food in the heating chamber, the output impedance of the microwave transmitting module is mismatched, resulting in serious energy loss. In the related art, a circulator is used to feed the energy emitted by the heating chamber into the heating chamber again so as to improve the energy utilization rate. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] In the process of using the circulator to realize energy...
