Microwave oven control device and microwave oven

Abstract

The invention discloses a microwave oven control device and a microwave oven. The microwave oven control device comprises a timer, a fan motor, an alternating current power supply, a magnetron temperature controller and a filter plate. The magnetron temperature controller is connected between the timer and the alternating current power supply. The filter plate is connected between the fan motor and the alternating current power supply. A relay is mounted in the filter plate. The timer is connected with the alternating current power supply through a driving coil of the relay, a fixed contact ofthe relay is connected with a first end of the alternating current power supply, a movable contact of the relay is connected with a first end of the fan motor, and a second end of the fan motor is connected to the filter plate. According to the microwave oven control device and the microwave oven, the circuit design is optimized, and the timer can control the on-off states of the relay on the filter plate to control the operation of the fan motor. Therefore, the risk that food is overheated and smokes and is on fire due to abnormal continuous operation of the microwave oven is avoided, and smoking and fire due to the fact that the temperature of a high-voltage transformer is too high can be avoided.

Description

technical field [0001] The invention relates to the technical field of microwave oven control, in particular to a microwave oven control device and a microwave oven. Background technique [0002] At present, the electrical circuit of a mechanical microwave oven is generally composed of components such as a timer, a temperature controller, a fan motor, a high-voltage transformer, a high-voltage capacitor, and a magnetron. When the timer time is set, the circuit will be automatically turned on, and the microwave oven will work automatically until the timer time returns to 0 and the microwave oven will stop working. [0003] In the electrical circuit of the related art, the timer motor and the fan motor are connected in parallel, which has the following defects: [0004] 1. When the quality of the timer is poor, if the timer motor cannot run, the timer cannot return to the time 0, which will cause the microwave oven to continue to run. When there is food in the oven cavity, th...

Problems solved by technology

[0004] 1. When the quality of the timer is poor, if the timer motor cannot run, the timer cannot return to the time 0, which will cause the microwave oven to continue to run. When there is food in the oven cavity, the food will be overheated and cause the risk of smoke and fire

[0005] 2. During the use of the microwave oven, when the internal motor coil of the timer is disconnected due to vibration and other reasons, the timer motor will stop running and the timer cannot return to time 0, which will cause the microwave oven to continue to run. When there is food in the oven cavity when the food is overheated, there is a risk of smoke and fire

[0006] 3. During the use of the microwave oven, when the connection wire of the internal motor of the timer is soldered due to long-term oxidation of the solder joints, the timer motor will also stop running and the timer cannot return to time 0, which will cause the microwave oven to continue to run. With food in the cavity, there is a risk of overheating of the food causing smoke and fire
