The scheme of the device and the principle of operation of the electric stove
Modern city apartments in high-rise buildings have only electrical wiring, without gas pipeline, therefore, electric stoves are installed in the kitchen. Many newcomers are interested in the principle of operation of the electric stove, as well as its device. In this article we will try to give a comprehensive answer.
Basic equipment
The device of any model of electric stove of domestic or imported production is almost similar, but they all have their original nuances. Example, modern Hansa electric stoves from Germany have a special configuration, but we will consider the standard option, which is in every model of electric stove. Traditionally, these products are a combined electrical appliance, designed for cooking, it unites:
- hob with burners;
- oven;
- lower drawer for storing dishes and sheets.
The principle of operation is standard for most electrical appliances: current, passing through the heater heats it to a given temperature. For convenient control on the front front panel there are regulators - they can be mechanical or electronic type depending on the product class. Usually, there are two indicators on the same panel: one, which notifies about the inclusion of the device in the network, and the second announces 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 a diagram of the device of a standard electric stove.
Decipher the notation:
- power regulator;
- terminal box;
- burner;
- support bar;
- oven temperature sensor;
- a loop;
- stopper;
- oven tena holder;
- ten ovens;
- internal facing panel;
- door latch latch;
- latch socket;
- insulating gasket;
- grill ten;
- rim of the burner;
- power cord;
- earth terminal;
- adjusting handles.
Varieties of electric stove surfaces
At the present stage of technology development models of electric stoves are divided into two categories depending on the type of hob.
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 cooking surface is resistant to mechanical damage from accidental falling of small kitchen utensils and heavy pans. There were also shortcomings:
- long cooking time;
- part of the thermal energy is wasted, especially after turning off the burners, which take a long time to cool down, heated kitchen air;
- cleaning the surface takes a long time, forces - you need to use special chemicals.
Glass ceramics
Modern electric stoves are equipped with a glass-ceramic surface, which looks very aesthetically pleasing and stylish. And what are its advantages?
- the entire cooking surface is covered with a high-strength ceramic sheet;
- heating occurs only in the area of the burner, ensuring safety of use;
- the smooth surface excludes accidental overturning of ware;
- the dimensions of the burners can be up to 60 cm in diameter;
- fast heating and cooling - works in the intensive mode the heating element only after a minute completely cools down;
- easy care - the surface is easy to clean with mild detergents.
The electrical circuit is arranged as follows, that when removing utensils from the burner automation instantly turns off the heater.
Management of such plates, usually, is carried out by means of touch sensors, which are located on the hob in a very convenient place, creating safety of their use.
Despite the many advantages, there are disadvantages:
- can not be cooked in aluminum and copper utensils - they leave unattractive marks on the surface, only stainless steel utensils with a smooth bottom can be used;
- it is a glass surface, subject to mechanical impacts from sharp objects, which in any kitchen in abundance.
Heating elements
The difference between electric stoves may be in the arrangement of their burners. Consider the main types.
Spiral burners
Visually, they are very similar to the heating element of an electric kettle - this is a normal heating element, which is designed to heat the kitchen utensils installed on it. Such burners are single and double type - the second option is different, that around the first spiral is the second. These devices are regulated by mechanical rotary switches, where smooth adjustment is used.
Pancake version
Such products have a solid surface, which is heated by two or more heaters, fixed on a metal base. Adjustment is carried out by special switches of rotary type, which connect TEN in various combinations. They have several provisions, they are called step power regulators - this is how they differ from previous devices for adjusting spiral burners.
To protect the products of spiral and pancake-type burners, the developers have come up with an original device, which automatically turns off the heater, if the pan temperature has reached this value, that its contents can spill out and flood the surface of the burner.
Halogen look
Different configurations of heating elements are placed under the glass-ceramic hob in any order, as designers come up with. The dishes are heated by a special halogen emitter: the place marked by the LED indicator heats up in a few seconds. It is good to cook food on such a hotplate without long worries, and energy consumption is not more 2 kilowatts per hour.
This option requires utensils made of cast iron or steel - this should be taken into account by all users when buying such a plate.
Heating control is carried out directly on the top of the hob using the touch buttons, lower cost models include standard control with regulators, located on the front control panel.
Ceramic devices
This type of heating element is similar to a maze, in which the spiral from a nichrome thread is put - the drawing of each ring is ideally thought over for that, 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 a halogen variant in one plate is applied. To control the heating of these devices are often used switches with smooth two-stage adjustment.
Oven
The heat necessary for preparation of various dishes in a case is made by means of a special configuration of Tenov, which are specially made on special technology for application in ovens of electric stoves. The amount of heating inside is regulated by a switch located on the control panel - a thermostat. Most ovens are equipped with a timer, which not only turns off the device at the right time, but can include - if the user pre-installs the required program.
Some models have convection - the fan distributes hot air evenly throughout the cabinet, so there is no need to turn over, example, duck carcass while roasting on a deck.
The entire surface of the oven in the most advanced models has a special high-quality enamel coating, thanks to which to maintain internal purity is quite simple. Example, the Hans brand has a special mode, when you turn on all the dripping fat instantly turns to ash.
How the grill works
Every modern electric stove has a device called a grill. To implement this function, several heating elements are used, whose action is aimed at that, that baking on different modes went evenly. Adjustment is combined, mechanical type regulator, located on the control panel.
Electric stoves are not only considered a unique product for quality cooking - they can be a highlight of the design of your kitchen interior.. Every buyer will find their own model, made in a classic or modern style - a variety of sizes and colors, the presence of a large number of functional features allows you to choose according to personal priorities.
