Multifunctional induction electrical appliances have long been used in metallurgy and the welding industry. Their production refers to high technology. An improved induction cooker circuit is actively used in the household industry (electric stoves). Even if the equipment fails, this is not a serious problem. But specialized service centers require a significant fee for their services. To save an impressive amount, you can repair the induction cooker with your own hands.
Accessories
The traditional induction cooker circuit consists of several key parts, each of which is designed to perform certain functions. Coordinated work of the unit is achieved due to the presence of the following elements:
- The primary winding (coil) is presented in the form of a massive copper conductor, which is tightly laid in the form of a spiral.
- The degree of heating of the device is continuously monitored by the sensor. In critical cases, the mechanism turns off the power, thereby avoiding damage to the unit and fire.
- The universal alternator circuit board operates exclusively at high frequency. The part is equipped with a heat sink of the output stage. The presence of a fan provides forced cooling of the entire mechanism.
- Ferrites are hidden in the body of the product, which form a ferromagnetic complex in combination with a coil.
- The generator is protected by a powerful housing that does not interfere with efficient airflow of the entire system.
Principle of operation
The induction cooker circuit is not so complicated if you understand how it works before using the product. The operation of the unit is built on electromagnetic pulses - the mechanism of the current flow when the total magnetic flux changes. By its principle of operation, the product is very similar to a classic transformer. A powerful induction-type coil is hidden under a glass-ceramic surface. Under normal conditions, the mechanism interacts with a current frequency of 20 to 200 kHz. The coil is used as the primary winding, and the dishes are the secondary, which the user places on top of the burner.
The scheme of the induction cooker is based on the fact that after placing the pan on the working surface, currents come into play, which perform heating. The glass-ceramic surface of the product glows well, but only from the dishes, and not from the built-in mechanisms.
Cooking food
Absolutely all the control circuit boards of the induction cooker boards are designed for certain dishes with a magnetic bottom. The hob automatically recognizes the suitable structure and instantly activates after turning the burner. Manufacturers allow the use of the following dishes:
- From stainless steel.
- Cast iron.
- Enameled, but only with a flat bottom.
If the dishes themselves are made of steel, but on top is covered with a thick layer of enamel, then such a product can be used.
Choosing a quality model
The circuit of a desktop induction cooker is constructed in such a way that everything depends on the voltage level in the house. If the indicators are lower than the required values, then the main fuse near the switchboard will be knocked out regularly, and the power cord will also burn.
If the consumer understands that there are still problems with the voltage, then it is better to study the scheme of the Endever induction cooker of lower power, which is equipped with the function of independently adjusting the required indicators. This is the easiest and most affordable option. But the heating rate of the installed capacity will be reduced. After purchasing the product, you must lay the cable yourself with the appropriate cross-section. For safety, a separate circuit breaker with suitable rated current can be installed.
Types of malfunctions
Recently, the induction cooker Galaxy GL 3054 has been most popular. The repair scheme for this product is notable for its simplicity and accessibility, due to which users do not need to spend a large amount on restoring the unit to work. The most common problems include:
- There is no reaction to the touch panel. If grease is present on the surface, the system may simply not recognize human touch. To solve this problem, it is enough to perform a careful cleaning of the surface.
- Several burners do not work. It is necessary to check the connection of the stove to the power source. From overheating, the connector of the inductor may fail.
- The cooling fan does not turn off. The cause may be a malfunction of the temperature sensor.
- The stove does not respond to dishes. For cooking, you can use only those pots and pans that were originally designed for such cooking surfaces. Otherwise, check the power supply and temperature sensor.
- The residual heat indicator is not displayed. Most often, the situation arises against the background of a breakdown of the temperature sensor. When replacing the device, you must check the reliability of the connection wiring to avoid possible fire.
Health recovery
In private residential premises and apartments, single-plate induction hobs are increasingly being used. Electrical circuits allow home craftsmen to independently carry out the necessary repair work. The first step is always to disconnect the product from the mains. Only after that the decorative surface is dismantled in order to get full access to the details. Any traces of soot, a change in the traditional colors of the elements, signs of melting should cause concern.
Experts recommend preparing an electric induction cooker circuit in advance, since in this case all repair work will be much faster. You can download the necessary document on the official website of the product manufacturer. Using a multimeter, you need to check the fuse box, cable and the contacts themselves. Be sure to inspect the spirals of induction coils. The products should not have cracks, as well as touches between the turns. It is necessary to test the serviceability of the connecting wiring. Chains are checked with a multimeter. Carefully remove the problem burner along with the generator board. The master will carefully examine the elemental base. Burned radio parts can be seen with the naked eye. When a problem is found, replace the failed parts. In this case, the induction cooker circuit will help. Doing it yourself is not so difficult if you prepare the necessary tools in advance.
Advantages and disadvantages
The modern induction cooker circuit allows you to achieve maximum efficiency, significant energy savings, as well as minimal risks of thermal burns. The product is an excellent assistant in any kitchen. The unit compares favorably with all gas and electrical analogues. The main advantages of the induction cooker are noticeable even to a beginner.
Special attention deserves the modern appearance of the product. The stove organically fits into any kitchen design, and even a child can take care of it. To clean the accumulated fat and other stains, you need to use a regular sponge with detergent. It is forbidden to use metal brushes and other products that can damage the surface.
After removing the frying pan or pan from the stove, the product is automatically turned off, due to which electricity is not wasted. Food is no different from what was cooked on ordinary gas. Additional amenities include the ability to adjust the temperature and the availability of several programs for high-quality cooking.
The disadvantages include the fact that users need to use certain dishes, which are made on the basis of ferromagnetic materials. Such plates are not sold immediately, when compared with the main competitors. The average buyer can not always afford to buy such a product.
Safety for humans
Recently, there have been many different discussions about the harm level of induction cookers. The principle of operation of such products is built on electromagnetic fields, the negativity of which is well known to everyone. Experts have proved that at a distance of 2 cm from the stove, the radiation is always above the permissible norm. If the pan is offset from the center of the burner, then the indicated norm will be overestimated in the region of 15 centimeters from the hob.
Recommendations
Quality connection of induction hobs in residential buildings takes a lot of free time. Before proceeding with the independent installation of the product, it is necessary to take into account the cross-section, phase power and the number of wires of the power cable between the hob and the home switchgear. After installation, you must adhere to the basic rules of operation, as well as regularly clean the surface from contamination. Due to this, the stove will last more than one year.
