Description

[0064] Figure 7 yes Figure 1 A schematic structural diagram of the detection module 600. (See attached diagram.) Figure 1 , Figure 3 and Figure 7 In particular, the processing device 100 may also include a detection module 600.

[0065] The detection module 600 can be disposed on the outside of the shielding feature to determine whether electromagnetic wave leakage has occurred in the processing device 100. In this invention, "electromagnetic wave leakage" means that the electromagnetic wave leakage exceeds a safety threshold.

[0066] The detection module 600 may include a detection circuit 610 and a conversion circuit 620.

[0067] The detection circuit 610 may be configured to emit light when electromagnetic wave leakage occurs in the processing device 100. The detection circuit 610 may include a light-emitting element 611.

[0068] The conversion circuit 620 can be configured to generate a reference signal based on the light intensity emitted by the light-emitting element 611, which is used to regulate the electromagnetic wave generating system and reduce the electromagnetic wave leakage of the processing device 100. The conversion circuit 620 may include a photosensitive element 621.

[0069] The electromagnetic wave processing device 100 of the present invention emits light when electromagnetic wave leakage occurs through the detection circuit 610. The conversion circuit 620 generates a reference signal based on the light intensity of the light emitted by the detection circuit 610. The electromagnetic wave generation system can then be adjusted according to the reference signal to reduce the amount of electromagnetic wave leakage. This not only effectively reduces the impact or interference on surrounding food and electrical devices, but also forms line isolation between the detection circuit 610 and the conversion circuit 620, preventing instantaneous damage to the conversion circuit 620 and other control components connected to the conversion circuit 620 when the amount of electromagnetic wave leakage is too large, thus further improving the reliability of the processing device 100.

[0070] In some embodiments, the photosensitive element 621 may be a photodiode. Correspondingly, the reference signal may be a voltage signal.

[0071] In other embodiments, the photosensitive element 621 may be a photoresistor. Accordingly, the reference signal may be a voltage signal or a current signal.

[0072] In some embodiments, the value of the reference signal may be proportional to the amount of electromagnetic wave leakage.

[0073] The controller 450 can be configured to stop the electromagnetic wave generation system from operating during the initial matching phase (by adjusting the frequency or impedance matching circuit to achieve impedance matching between the electromagnetic wave generation system and the object to be processed 500) when the value of the reference signal is greater than a first threshold, so as to stop electromagnetic wave leakage.

[0074] The controller 450 can also be configured to, during the continued processing phase (heating of the workpiece 500 after impedance matching), when the value of the reference signal is greater than a second threshold, control the electromagnetic wave generating system to reduce the power of the electromagnetic waves it generates or stop operating, so as to mitigate or stop electromagnetic wave leakage.

[0075] In the absence of electromagnetic wave leakage, the power of the electromagnetic waves generated by the electromagnetic wave generation system can be greater in the continued processing stage than in the initial matching stage, thereby improving the processing efficiency of the object 500.

[0076] The second threshold can be greater than the first threshold. The first threshold can correspond to an electromagnetic radiation density of 5 W / m².2 The second threshold can correspond to an electromagnetic radiation density of 40 W / m². 2 .

[0077] In some further embodiments, the controller 450 may be configured to, during the continued processing phase, when the value of the reference signal first appears to be greater than a second threshold, control the electromagnetic wave generating system to reduce the power of the electromagnetic waves it generates (e.g., reduce by 50%), and if the value of the reference signal is still greater than the second threshold after the power reduction, control the electromagnetic wave generating system to stop operating, so as to improve safety and user experience.

[0078] In some embodiments, the detection circuit 610 may further include a detection line 612 and a rectifier filter circuit 613.

[0079] The detection circuit 612 can be configured to acquire and process electrical signals related to electromagnetic wave leakage from the device 100; The rectifier and filter circuit 613 can be configured to convert the electrical signal collected by the detection line 612 into a DC signal and power the light-emitting element 611.

[0080] In some embodiments, the detection line 612 may include a receiving antenna disposed outside the shielding features of the door 300 and the cylinder 210 to receive leaked electromagnetic waves.

[0081] In other embodiments, the detection circuit 610 may be configured to be electrically connected to the shielding feature of the door 300 or the shielding feature of the cylinder 210 at a first connection point and a second connection point, i.e., the detection line 612 is an electrical connection. The distances between the first connection point and the second connection point and the grounding point of the shielding feature are different, so as to determine whether electromagnetic wave leakage has occurred in the processing device 100 by the induced voltage change of the shielding feature under the action of leakage electromagnetic waves.

[0082] In some further embodiments, the shielding feature of the cylinder 210 may be grounded to ensure the reliability of the electrical connection.

[0083] The detection circuit 610 can be configured to be electrically connected to the shielding feature of the door 300 to improve the sensitivity of electromagnetic wave leakage detection.

[0084] In some further embodiments, the detection circuit 610 may be configured to be electrically connected to the edge of the shielding plate 330 to improve the sensitivity of electromagnetic wave leakage detection.

[0085] Specifically, the one with the higher potential among the first connection point and the second connection point can be located at the end of the flange in the gap 3311.

[0092] In some further embodiments, the light-emitting element 611 may be fixed between the front cover 360 and the support member 310, so that the conversion circuit 620 can also sense changes in light intensity when the door 820 is opened, regulate the electromagnetic wave generating system, and reduce the impact of electromagnetic waves on the user.
