Freestanding

The working environment of Freestanding induction cooker is much worse than that of TV. It is always in a hot and humid environment, and induction cooker consumes high power, so the wiring requirements are strict and the quality is relatively good. Plugs and sockets. It must have a lot of elements so as not to damage the cooker. According to statistics, the induction cooker in front of every TV is currently two kinds of electrical appliances for maintenance. As a rough percentage, every 100 TVs will cause about 20 to 30 damages per year. The failure rate of Freestanding induction cookers is much higher than that of TVs, over 50. This means that on average more than 50 induction cookers fail every year. What is the reason for the high failure rate of the induction cooker? The quality is not always bad. Among the substandard furnaces, there are also many high-end furnaces that cost more than 500 yuan. Obstacles caused by human factors in the later use account for the majority.

Freestanding induction cooker

1. The voltage is unstable.

Freestanding induction cookers are the most power-hungry of all appliances. When it is turned on, such as cooking, hot pot and boiling water, the general power consumption is more than 1500 watts (the AC ammeter measures 8A), and a good induction cooker can reach 2200 watts (the AC ammeter measures 10A). And the current is continuously flowing. So any poor contact of any wire connector in a circuit operating at such a large current will cause voltage instability. Up and down. In light of the damage to the secondary power supply circuit, the power tube (IGBT) will be burned out. Therefore, it is recommended to use a dedicated line for power supply to the induction cooker. The fewer joints the better. The socket at the end should be a high-quality, thick copper socket with a current above 16A. Insert more force to prevent slippage. In this way, failures due to voltage can be effectively reduced.

2. Water intake

Water ingress is definitely human error. However, there are many failures caused by inattentive use. Some people overflowed the pot and caused water to enter when cooking. Especially hot milk or rice porridge is easy to overflow the pot. Although once or twice has been found undamaged, it will leak to the board sooner or later if it is not taken seriously.

3. High temperature

Since the Freestanding induction cooker relies on the internal fan to dissipate heat, it should be repaired and maintained when the fan feels that the fan is not spinning or the fan is out of air. High temperature control circuits are designed in-house, but not all such circuits are effective. Also, be careful with boiling water and fried foods for long periods of time. Induction cookers need proper heat dissipation.

As with high-temperature damage to a TV, dust in the stove should be thoroughly cleaned at least every two years. More dust adheres to the surface of the circuit board, hindering heat dissipation. Excellent hands-on ability allows you to open the front cover, remove the fan and heating coil, and unscrew the circuit board for a thorough cleaning. Then install it carefully.

Another reason is high humidity. It is the high humidity circuit board that is leaking water. Also, too much fumes can make the board too dirty, and dust can stick to it, making the Freestanding induction cooker very greasy inside.

As for the oil stains inside and outside the Freestanding induction cooker, I have said it before, but when using soot, mosquito coil ashes, or firewood, sprinkle plant ashes on the surface, and then wipe it with a cloth, it can be effectively removed. It also prevents water ingress of circuit boards caused by liquid cleaning.
