Controls that are directly responsible for adjusting the power of the burners. At the same time, other control elements can be provided in the design. For example, rotary knobs are often combined
with buttons, to which additional functions are designated.
—
Rotary knobs. The traditional, most common option, found in hobs of all types — both gas and
electric — and price categories. Rotary knobs are quite convenient and functional while being simple in design and inexpensive.
—
Pop out knobs. A variation on the rotary knobs described above, in which the control knobs can be recessed into the control panel. The specific design may be different: in some models, the handle is recessed during operation; in others, it remains recessed until the corresponding burner is in use and pops out from the panel during operation. This design gives the hob a neat appearance, reduces the number of places where dirt can accumulate, and makes the front panel easier to clean. Unlike rotary knobs, pop out knobs are mainly used in electrical models.

Touch controls. Touch controls are found only in electric hobs. This option has several advantages. First, the touch controls look neat and have no protruding parts, making them easy to clean. Secondly, the control is carried out with light touches and req
...uires minimal effort. Thirdly, touch controls give the stove a stylish and technological appearance. On the other hand, such stoves are quite expensive and may be inconvenient for some users who are accustomed to traditional rotary knobs. Therefore, relatively few touch control models are produced. Usually, it is compact hobs for 1 – 2 burners without an oven, where rotary knobs would not be very appropriate.
— Slider. A kind of touch control represented by sensitive tracks. To adjust the heating intensity of the burners or quickly access other settings of the hob, slide your finger along the corresponding touch scale to the selected value. The convenience of slider control also lies in the fact that you can immediately set the required heating power by clicking on a certain area of the scale.
— Push-buttons. Control, carried out exclusively with the help of buttons, is used very rarely in modern stoves. Most models with such controls are compact portable stoves for one or two burners: it is not always convenient to equip such devices with rotary knobs, but the buttons fit well into the design. They are also cheaper than touch controls. On the other hand, the price difference is not so great, and the buttons are somewhat less convenient to use and clean — mainly for this reason they are noticeably less common.The residual heat indicator is is used in electric stoves. It allows you to determine the presence of hot burners when the power is off, thus reducing the risk of burning yourself on a burner that has not had time to cool down. In addition, the presence of such an indicator helps to save energy.
The heating power, the performance of the device and the speed of cooking depend on the diameter of the burners. The larger the burner, the more heat dissipation it has. Also, the diameter of the burner allows you to determine what sizes of dishes are suitable for use on the hob. Indeed, for induction models, this value is critical for high-quality heating. Burners can have the following diameter:
- small — about 145 mm, power within 1200 W;
- medium — about 180 mm, power within 1700 W;
- large — about 220 mm and more, power within 2000 W.
Some hobs use dual-circuit burners that allow you to adjust the diameter of the heating zone. If it is indicated that the diameter of the burner is 180, 200, 220 mm, then the heating zone on a particular burner can be narrowed and/or expanded, depending on the size of the dishes used.
