[Why the Soymilk Maker Does Not Turn] What should I do if the Soymilk Maker does not turn?
What should I do if the Soymilk Maker does not turn Soymilk machine does not turn how to repair
As people pay more and more attention to health care, soymilk machine is gradually becoming more and more popular with consumers, but sometimes soymilk machine also encounters such and such problems The problem is that the soymilk machine does not rotate, which is one of them, which causes a lot of trouble for us to use, so what’s the matter with the soymilk machine motor not rotating? How to repair the motor of the soymilk machine not turning? Below, I will give you a detailed introduction to the reasons why the motor of the soymilk machine does not turn and other relevant information.
1. What’s wrong with the motor of the soymilk machine not turning?
1. The motor in the machine is damp and the coil is short-circuited.
The soymilk machine motor does not rotate
Solution: replace the series motor.
2. The relay cannot be pulled in or the legs are broken.
Resolution: Replace the relay.
3. The continuous use time is long, which leads to the high temperature transition of the series motor.
Solution: Turn off the switch, suspend use, and slowly cool down the motor.
4. Improper use leads to water in the machine and partial short circuit of the computer board.
Solution: Dry the computer board and the water inside the machine with a hair dryer.
5. What is the reason why the Joyoung Soymilk Maker can only heat the motor but does not turn?
Usually the relay or motor is damaged.
The soymilk machine motor does not rotate
Second, what is the matter with the soymilk machine being repaired but the motor does not rotate?
When repairing the soymilk machine, most people always say that after the machine is repaired, use the cleaning function to test the machine and the motor can rotate, and add water to test the machine with the whole bean function, and do not make beans after the water is boiled. In fact, we When repairing most soymilk machines, it is not possible to directly add water to test the machine, because the water can not produce foam after boiling, and most machines have two sensors, one is the water level detection, that is, the long sensor needle, the other It is the anti-overflow detection electrode, that is, the short induction needle, so when we repair the machine, we only need to add soapy water to the clean water or add some detergent to the machine, and the machine can proceed according to the program. The water level sensor needle detects the water level and sends the signal to the main board. The main board gets the signal and starts to drive the heating rod to heat the water. After the water boils, more and more foam is generated. The foam will rise with the continuous boiling of the water in the bucket. When the foam rises to contact After reaching the anti-overflow electrode, the anti-overflow electrode immediately sends a signal to the main board to inform the main board that the water has boiled, and the main board stops heating the heating rod immediately, and at the same time outputs a signal to drive the motor to start beating beans. During the whole process of making soy milk, the above process It will repeat several times until the machine alarms.
Of course, this is only for most models. Some genuine Joyoung machines are equipped with temperature sensors in the water level detection needle. This kind of machine can be tested directly with clean water, because the water boils to a certain level. After the temperature is reached, the motor can start to make beans, but now there are fewer models of this type, because manufacturers do not use temperature sensors in order to save costs.
Third, the maintenance process of the Midea soybean milk machine motor not running
A Midea soybean milk machine was not powered on because of the water, and the power supply part was repaired by a friend After that, there was a fault that the motor could be heated but could not be rotated. If I could not figure it out, I came to me for help. I disassembled the analysis circuit. Power supply, the triac is triggered by the optocoupler controlled by the single-chip microcomputer. I first short-circuit the T1 and T2 pins of the thyristor, and use the fruit and vegetable juice file to test (the motor in this file will turn immediately, and the heating plate will not participate in the work), the motor can rotate , indicating that there is no problem with the motor and the bridge rectifier, and then short-circuit the output pins 4 and 6 of the optocoupler, the motor can also rotate, indicating that there is no problem with the triac. The signal is pulled low to control, artificially pull the MC signal to the ground, and the motor can also rotate, indicating that the optocoupler is also normal, and then check that the MC signal of the single-chip microcomputer is at a high level at any time, and no abnormality is found in the peripheral components, and the fault is determined. On the microcontroller, you can only replace the original computer board, but the price is too high.
Four. Soymilk machine motor maintenance method
1. Motor maintenance
Fully automatic commercial soybean milk The principle is to grind the beans into fine soy milk through high-speed collision cutting. Due to the characteristics of the ultra-high speed of the motor and the large heat generation, the commercial soybean milk machine is equipped with a forced cooling system for the motor. However, since it takes a long time to complete a soybean milk production from the beginning, the work of the motor is intermittent. Due to the production process It will be heated and boiled, so there will be a lot of heat transferred to the motor, so to protect the motor, we recommend letting the soymilk maker rest for a period of time, about 15-20 minutes, or Add cold water and press the stir button to stir once (it is best not to use this method).
2. Maintenance of consumable parts such as knife set and mushroom head
The motor life of the fully automatic commercial soybean milk maker is quite long, and it is more prone to problems The only thing is that the crushing system combined with the motor is easy to be damaged, because these accessories are loss-type accessories, but if you pay attention to maintenance during the use process, the life can be greatly extended. It is best for non-professionals not to disassemble these accessories, especially the soymilk maker with a large capacity of more than 20 liters. Its knife group and mushroom head – two parts directly related to grinding and cutting, proper maintenance can greatly increase the number of uses. . The culprit that damages these two components is heat, so it is best to choose a maintenance method that can stop the soymilk machine from working for 15-20 minutes to cool down.
