Controls
The main type of control elements in a microwave oven.
— Rotary knobs. Mechanical rotary knobs most often are used in the simplest low-cost models: one knob sets the heating power, and the other — the operating time. The accuracy of such adjustments is not very high; this is especially true for the operating time. However, there are also quite advanced microwaves with similar controls — they may provide other ways to use rotary knobs, as well as additional controls (for example, buttons).
— Push-buttons. Control using buttons, usually, implies the presence of a display — otherwise, it would be difficult to control the operation. This option allows you to set the parameters more accurately — in particular, the timer in push-button models is usually electronic. In addition, it is well-suited for models with predefined recipes, special modes, etc. Therefore, buttons are a sign of a model with advanced features, the functionality of which is not limited to constant heating at a certain power.
— Rotary knobs + touch controls. Controls include both rotary knobs and touch controls. The main features of both are described above. Such controls, as well as purely touch controls, are found mainly in fairly advanced models. On the one hand, rotary knobs are more convenient for some tasks (for example, adjusting power or selecting an operating mode). On the other hand, they somewhat complicate the design of the control panel and make it difficult to cle...an. Therefore, this option has not received much popularity.
— Touch controls. Another type of control, similar to the buttons described above, with one difference — the role of the buttons, in this case, is played by touch sensors. Touch controls look more advanced than push-buttons, are easier to operate, and have no protruding parts, making them less dirty and easier to clean. The disadvantage of touch controls can be called a higher cost, which is why this option is found mainly in expensive models.
— Pop-out knobs + touch controls. Pop-out knobs are a variation of the rotary knobs described above, in which the knobs can be recessed into the control panel. Usually, pop-out knobs are designed to stay outside only during the direct setting of the operating mode. And for the time when the oven is not in use or works in one mode, they can be hidden. It gives the unit a neat appearance, reduces the places where dirt can accumulate, and makes the front panel easier to clean. And touch controls complement the style of the device and underline its premium performance.
Inner coating
— Enamel. The most inexpensive and common type of internal coating. The strength and reliability of enamel are generally sufficient for most cases. This material does not tolerate high temperatures, is relatively easily damaged and is prone to sticking small pieces of food and splashes, which makes cleaning difficult. As a result, the enamel is used mainly in inexpensive microwave ovens.
— Acrylic. Another fairly inexpensive material. It is not as widespread as enamel, but mainly because it appeared relatively recently. The main and only advantage of such a coating is its low cost. At the same time, it is not durable and does not tolerate strong heat, which is why it is used mainly in low-power models with a basic set of features.
- Stainless steel. In addition to its solid appearance, the steel coating has good strength and the ability to withstand high temperatures, and it is easy to clean. It is one of the best options if you plan to use the built-in grill extensively. In general, models with such a coating are noticeably more expensive than enamel ones, but this is due not so much to the coating as to more advanced features.
— Ceramics. Due to their hardness, ceramics resist scratches very well, and food particles practically do not stick to them. It makes these coatings very easy to clean. Their main disadvantage is fragility.
- Non-stick. This term may refer to various types of special coatings that prevent food from stick...ing. The best-known option is Teflon. This material has excellent non-stick properties. It is easy to clean but requires careful handling because it scratches easily. At the same time, it is believed that scratches lead to the release of harmful substances. Although, there is no unambiguous evidence for this. But with high heating, Teflon breaks down with the formation of harmful substances. However, in a microwave oven, such heating of the coating is almost impossible to achieve; and where there is such a possibility (for example, in models with a powerful grill), other heat-resistant non-stick materials are usually used.
