Problems solved by technology

[0002] The traditional microwave heating technology uses the magnetron to generate microwaves to heat the object to be heated. However, the distribution of the electric field strength of the microwave in this heating method is prone to unevenness, so that the part of the object to be heated located in the weak electric field area will suffer due to the weaker absorption intensity. A weak electric field produces a low heating area without significant heating, while the part of the heated object located in the strong electric field area will produce a high heating area that is significantly heated due to the strong electric field absorption intensity, thus causing the heated object to form after being heated by microwaves. Condition of uneven heating
[0003] In addition, in order to increase the temperature of the object to be heated in the low heating area, the electric field strength distribution can generally be changed by a mechanical turntable or a microwave stirrer, but the effect is still limited

Abstract

The invention discloses a distributed microwave phase control method, which comprises the following steps that a plurality of phase control power modules input microwaves into a cavity through each input port, so that the microwaves in the cavity are distributed in a first electric field; and each phase control power module adjusts the phase of the microwaves input into the cavity by each input port, so that the microwaves in the cavity generate second electric field distribution complementary to the first electric field distribution due to the change of the phase.

technical field [0001] The invention relates to microwave control technology, in particular to a distributed microwave phase control method. Background technique [0002] The traditional microwave heating technology uses the magnetron to generate microwaves to heat the object to be heated. However, the distribution of the electric field strength of the microwave in this heating method is prone to unevenness, so that the part of the object to be heated located in the weak electric field area will suffer due to the weaker absorption intensity. A weak electric field produces a low heating area without significant heating, while the part of the heated object located in the strong electric field area will produce a high heating area that is significantly heated due to the strong electric field absorption intensity, thus causing the heated object to form after being heated by microwaves. The condition of uneven heating. [0003] In addition, in order to increase the temperature o...
