Comparison Whirlpool OAKZ9 7921 CS NB vs Whirlpool AKZM 8420 NB

The number of cooking modes provided in the design of the oven. In this case, the cooking mode means the general opertaion mode — for example, “heating”, “heating + convection”, etc. Accordingly, this indicator strongly depends on additional equipment (see "Features"). However, even in similar models, the number of modes may be different. In general, the more cooking modes, the more cooking options, the easier it will be to choose the optimal mode for a specific situation.

The number of preinstalled cooking programmes stored in the oven's memory — usually designed for a specific dish or just a defrost mode. If you have the appropriate programme, you do not have to keep track of the time, manually change the temperature and rearrange the dish in the oven — just put the ingredients there and start the programme, and the device will do the rest on its own. At the same time, unlike individual cooking modes (see above), the programmes are more complex — they provide changing temperatures, turning on special modes, turning off when time has elapsed, etc. The larger the set of automatic programmes, the wider the possibilities of the oven; their number in modern models can be in the tens. On the other hand, such programmes cannot be changed at will, so if you need both creativity and maximum convenience, you should pay attention to models with the ability to record custom programme in memory.

The number of layers of glass in the viewing window of the oven door.

Modern models, usually, have from 2 to 4 glasses. The more glasses, the less heat loss and the more economical the oven, but this parameter also affects the cost.

The presence of an automatic door closer in the design of the oven.

Such a device is responsible for pulling the door when closing, and in some models, when opening. The idea is that the user does not need to close/open the door completely — just pull it to the right place, and then the door will be smoothly brought to a fully open or closed state by the door closer. Such a system performs two functions. Firstly, it reduces to almost zero the risk of leaving the oven not completely closed (which is fraught with various unpleasant situations): the auto-closer is usually able to attract even a fairly wide open door. Secondly, such a device provides a very smooth opening and closing, without shock, which has a positive effect on the service life of the entire oven.

Type of guides for installing baking sheets that are used in the oven.

— Frame. Classic guides have the form of slots with protrusions in the side walls of the oven. This design is simple and inexpensive. However, it is not very convenient — when removing baking sheets, you have to pull your hand into a heated oven, which means you will need a mitten or potholder. And the extraction itself may require effort, especially if the guides are dirty and the trays go tight in them.

— Telescopic. Retractable guides on which the baking sheet “leaves” the oven, usually, immediately when the door is opened. Such devices are more convenient than frame ones, but they are more expensive and not suitable for all situations (for example, sometimes to check a dish you only need to open the lid without pulling it out). Therefore, in most models, telescopic guides are only on one level. But telescopic guides on two levels or even three levels already classifies the device as a top segment.

The type of inner cleaning provided in the oven. Note that pollution has to be removed with a rag or sponge, but modern ovens often provide various tricks that facilitate the process. The options might be:

— Catalytic. A special wall coating is used in ovens with this cleaning method: it breaks down fats and other stubborn dirt into constituent elements that can be easily removed. The effectiveness of such a coating decreases over time, but it is enough for at least several years of full use. It should be noted that the catalytic coating can be implemented by applying it to special removable plates that are installed on the back or side walls of the oven chamber.

— Steam cleaning. Cleaning with hot steam, which softens dried-on dirt and partially breaks down fats. In some models, there is a built-in steam generator for this, in others it is enough to put a container of water in the working chamber and turn on the cleaning program.

— Pyrolytic. Cleaning by heating the chamber to a very high temperature — about 500 ° C. At this temperature, most of the contaminants are incinerated into ash, which can then be easily removed. Pyrolytic cleaning is considered the most effective, but ovens with this function are expensive, time consuming, require significant electricity/gas consumption, and can lead to unpleasant odors.

The country in which, according to the manufacturer, this or that model is manufactured. Even though most of the capacities are concentrated in China, European factories for the production of household appliances have not disappeared. And certain models can be produced on them. In general, such a division into a Chinese or European factory ( Germany, Italy, Poland, Turkey) should not particularly affect the quality of products, but still the stereotype of a reliable European assembly is present in us. However, it is possible that the model may have a country of manufacture, for example, Poland, and in the store under the same article, you will meet China.
