Residual heat indicator
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.
Burner power
Rated burner power. This parameter allows you to estimate how much electricity the burner will spend when operating at maximum heating intensity. At the same time, the heat transfer power of different burners can be different, and the actual heating efficiency will also greatly depend on the specs of the dishes. As a result, it hardly makes sense to evaluate the operating capabilities of the stove by the power of the burners. It is quite possible to proceed from the fact that the burner will be enough for a dish of the same diameter.
Child lock
A security measure that allows you to block the controls of the stove. It will be useful in families with small children: when the lock is on, a curious child will not be able to turn on the stove or change settings. To unlock, one needs to perform certain actions, which are easy for an adult and too complex for a child: for example, you need to press two specific buttons simultaneously.
Display
A display on the stove control panel. Usually, it is a very simple one-colour display : 3-4 digits plus a few additional characters (for example, a thermometer icon and a clock icon). However, even on such a display, almost all important information related to the stove operation can be displayed: heating temperature, clock, timer settings, and other relevant data. Thus, the display significantly simplifies the management of the stove and makes it more convenient.
For technical reasons, this function is mainly used in electric stoves; there are also gas models with displays, but they are extremely few.
