Tank content e.g. cleaning fluid, heating device for use in e.g. dishwasher, has microwave source providing microwave input for heating tank content stored in tank of flow dishwasher, where source is formed as vacuum drift tube

摘要

The device has a microwave source (27), which provides a microwave input (30) for heating tank content such as cleaning fluid (7), stored in a tank (9) of a cleaning device such as flow dishwasher (1). A wall limiting the microwave source is arranged in a base or into the tank. The source has a hollow space provided in a hollow conductor extending into the content. The source is formed as a vacuum drift tube, which generates vibrations within the microwave range of about 0.3 to 300 gigahertz.
