Features of the device electric cooker

Modern city apartments in high-rise buildings have only electrical wiring, without a gas pipeline, therefore in the kitchen electric cookers are installed. Many new settlers are interested in the principle of the electric stove, as well as its structure. In this article we will try to give a comprehensive answer.

Basic equipment

The device of any model of electric stoves of domestic or imported production is almost the same, but everyone has their own original nuances. For example, modern Hansa electric stoves from Germany have a special package, but we will consider the standard version that every model of electric stove has.Traditionally, these products are a combined electric appliance designed for cooking, it combines:

• cooking surface with burners;
• oven;
• bottom drawer for storing dishes and baking sheets.

The principle of operation is standard for most electrical appliances: the current passing through the heating element heats it to a predetermined temperature. For convenient control on the front of the front panel are located regulators - they can be mechanical or electronic type, depending on the class of the product. As a rule, on the same panel are located two indicators: one, announcing the inclusion of the device in the network, and the second notifies about the inclusion of the oven. On some plates there is only the first indicator. With the help of regulators, users can set the cooking mode on any hob or in the oven.

The figure below shows the layout of a standard electric cooker.

We decipher the notation:

1. power regulator;
2. terminal box;
3. hob;
4. support plate;
5. oven temperature sensor;
6. a loop;
7. stopper;
8. holder of the oven;
9. Teng oven;
10. internal facing panel;
11. door catch;
12. latch socket;
13. insulating gasket;
14. Teng for grilling;
15. ring rim;
16. power cord;
17. ground terminal;
18. adjusting knobs.

Variety of surfaces electric stoves

At the present stage of development of technology, electric stove models are divided into two categories depending on the type of cooking surface.

Enamel

Classic electric stoves - enameled surface with cast iron burners. The advantages of such a device are obvious:

• low cost;
• easy maintenance and repair.

In addition, the coating of the hob resistant to mechanical damage from accidental dropping of small kitchen utensils and heavy pans. Not without flaws:

• long cooking time;
• part of the heat energy is wasted, especially after turning off the hotplates that cool down for a long time, heating the kitchen air;
• cleaning the surface takes a lot of time, effort - you need to use special chemicals.

Glass ceramics

Modern electric stoves are equipped with a glass-ceramic surface that looks very aesthetically pleasing and stylish. And what else are its advantages?

• the entire hob is covered with high-strength ceramic sheet;
• heating occurs only in the zone of the burnerthat ensures safety of use;
• smooth surface eliminates accidental tipping dishes;
• dimensions of the burners can be up to 60 cm in diameter;
• fast heating and cooling - the heating element operating in intensive mode only cools down completely after a minute;
• easy care - the surface is easy to clean with mild detergents.

The electrical circuit is designed in such a way that when the dishes are removed from the burner, the automation instantly turns off the heating element.

These plates are usually controlled by touch sensors, which are located on the hob in a fairly convenient location, creating a safety of their use.

Despite the abundance of advantages, there are also disadvantages:

• you can not cook in aluminum and copper dishes - they leave unattractive traces on the surface, you can only use stainless steel dishes with a smooth bottom;
• This is a glass surface exposed to mechanical stress from sharp objects, which are abundant in any kitchen.

Heating elements

The difference between electric stoves can be in the device of their burners.Consider the basic types.

Spiral type burners

Visually, they are very similar to electric kettle heating element - This is an ordinary heater, which is designed to heat the kitchenware installed on it. Such rings are single and double - the second option is different in that the second spiral is located around the first helix. These devices are regulated by mechanical rotary switches that use stepless adjustment.

Pancake option

Such products have solid surfacewhich is heated by two or more heaters mounted on a metal base. The adjustment is made by special rotary switches that connect the heating elements in various combinations. They have several positions, they are called step power regulators - this is how they differ from previous devices for adjusting spiral burners.

To protect the products of the spiral and pancake-type burners, the developers came up with an original device that automatically turns off the heating element if the temperature of the pan has reached such a value that its contents can spill out and fill the burner surface.

Halogen view

Different configurations of heating elements are placed under the glass-ceramic hob in random order, as the designers come up with. The dishes are heated by special halogen emitter: The place indicated by the LED indicator heats up in a few seconds. On such a burner, it is good to cook foods without prolonged languor, and the power consumption is no more than 2 kilowatts per hour.

This option requires dishes made of cast iron or steel - this must be taken into account by all users when purchasing such a plate.

Heating is controlled directly on the top of the hob by touch buttons, in lower-cost models, standard control is enabled using knobs located on the front control panel.

Ceramic devices

This type of heating element is similar to a maze in which it is laid. nichrome filament spiral - the drawing of each burner is thought out ideally so that the spiral heats the maximum area. These products are mounted directly under the glass-ceramic surfaces of the panel, where cooking takes place, quite often their combination with the halogen variant is used in one plate.To control the heating of these devices are often used switches with a smooth two-step adjustment.

Oven

The heat necessary for cooking various dishes inside the cabinet is produced using a special configuration of heating elements that are specially manufactured using a special technology for use in ovens of electric stoves. The amount of heating inside is regulated by a thermostat switch located on the control panel. Most ovens equipped with a timer, which not only turns off the device at the right time, but also can turn it on - if the user installs the necessary program in advance.

Some models have convection - the fan distributes the hot air evenly throughout the cabinet, so there is no need to turn, for example, the duck carcass during baking on the pan.

On the entire surface of the oven in the most advanced models applied special high quality enamel coating, thanks to which to maintain internal cleanliness is quite simple. For example, the Hans brand has a special mode - pyrolytic cleaning, with the inclusion of which all the dripping fat instantly turns into ashes.

How does the grill work

Each modern electric stove has a device called a grill. To implement this function, use several heating elements, whose action is aimed at ensuring that the baking in different modes went evenly. The adjustment is made by a combined, mechanical type regulator located on the control panel.

Electric stoves are not only a unique product for high-quality cooking - they can be a highlight of the design of your kitchen interior. Each buyer will find his model, made in a classic or modern style - a variety of dimensions and colors, the presence of a large number of functional features allows choose an electric stove according to personal priorities.
