Embodiment 1
[0084] The present invention is realized by the following technical solutions: as figure 1 As shown, a multi-magnetron microwave heating device performance testing system is used to test the performance of a microwave heating device in which multiple magnetrons are fed into a microwave heating cavity at the same time. The testing system includes sampling units connected in sequence, AD The conversion module and the data processing and display unit are characterized in that: the sampling unit includes a system sampling module and a single-tube sampling module connected with the magnetron in one-to-one correspondence, and the single-tube sampling module includes a single-tube power supply sampling module, a magnetron parameter The sampling module, microwave power meter, system sampling module, single-tube power supply sampling module, magnetron parameter sampling module, and microwave power meter are respectively connected with the AD conversion module.
[0085] The system sampl...
Embodiment 2
[0098] This embodiment is optimized on the basis of Embodiment 1, and the performance testing method uses a performance testing system to collect, analyze, process and display data.
[0099] The data that needs to be collected in the performance testing method are:
[0100] Water mass M for water load W , in step S1, the mass of the water load is calculated after measuring the volume by a measuring instrument such as a graduated cylinder, or the mass of the water load placed in the microwave heating cavity is directly weighed;
[0101] Initial water temperature T1, in step S1, directly measure the initial temperature of the water load through a thermometer or a temperature sensor;
[0102] Test the water temperature T2, in step S2, directly measure the temperature of the water load when testing the performance of the microwave system through components such as a thermometer or a temperature sensor;
[0103] The start time time1 when the magnetron starts to work, in step S2, th...
Embodiment 3
[0144] In this example, on the basis of Example 1 or 2, three loads were prepared according to the mass ratio of 0.5N:1N:1.5N for the performance test of the microwave heating device. Among them, N is the number of magnetrons working in the corresponding microwave heating device.
[0145] For example, there are 9 working magnetrons in the microwave heating device, that is, when N=9, the masses of three water loads are 4.5KG, 9.0KG, and 13.5KG respectively.
[0146] Another example: there are 10 working magnetrons in the microwave heating device, that is, when N=10, the masses of three water loads are 5.0KG, 10.0KG, and 15.0KG, respectively.
