Embodiment Construction

[0022] refer to figure 1 , the present invention is a kind of leakage detection method, comprises the following steps:

[0023] 1). Transfer the microwave oven 1 towards the detection device 3, and use the push device 2 to push the microwave oven 1 to the detection position, and turn on the power of the microwave oven 1, so that the microwave oven 1 is in the working state;

[0024] 2). Using a number of detection probes 4 on the detection device 3 to detect the leaked wave values ​​of multiple detected positions of the microwave oven 1, each detection probe 4 moves relative to the microwave oven 1 along a preset trajectory, and measures the Leakage value of position;

[0025] 3). The detection device 3 compares the value measured by each detection probe 4 with the standard value, and judges the qualified degree of the microwave oven 1;

[0026] 4). Turn off the power of the microwave oven 1 to complete the detection.

[0027] Specifically, when this leakage wave detection ...

Abstract

The invention discloses a leaky wave detection method. According to the method, a microwave oven is conveyed by a microwave oven conveying device. After that, the position of the microwave oven is adjusted by a pushing device. Finally, the combination part of the oven door and the oven body of the microwave oven, and the front side of the microwave oven are systematically detected by a detection device. In this way, the values of leaky waves at a plurality of detected positions on the microwave oven can be measured. The method is comprehensive in detection range. In combination with the valuesof leaky waves at the plurality of detected positions, the overall quality of the microwave oven can be comprehensively evaluated. As a result, the test result of the method is higher in reliability.The method is applied to the field of electric appliance detection.

Description

technical field [0001] The invention relates to the field of electric appliance detection, in particular to a leakage wave detection method. Background technique [0002] A microwave oven is a modern cooking stove that uses microwaves to heat food. The microwave oven is composed of a power supply, a magnetron, a control circuit, and a cooking cavity. The power supply provides a high voltage of about 4000 volts to the magnetron. Under the excitation of the power supply, the magnetron continuously generates microwaves, and then couples into the cooking cavity through the waveguide system. Near the entrance of the cooking cavity, there is a rotatable stirrer, because the stirrer is a fan-shaped metal, which can reflect microwaves in all directions after rotating, so the microwave energy can be evenly distributed in the cooking cavity. [0003] The principle of microwave heating is that when microwaves irradiate food, there is always a certain amount of water in the food, and w...
