Problems solved by technology

In contrast to domestic appliances, dishwashing machines for commercial use are subject to the problem that the throughput times must be considerably reduced.

However, one problem with commercial dishwashing machines such as these is that, when the front door is opened, considerable amounts of vapor in. the form of water vapor can escape into the working environment, for example a large kitchen, thus considerably increasing the temperature and the air humidity in this area.

This water vapor makes the work of the operator considerably harder.

For example, operation of machines such as these by those wearing spectacles is subject to considerable difficulties.

However, in practice, this procedure is not only associated with the disadvantage of reduced throughput of plates and dishes to be cleaned,
