Abstract:
A fuse mechanism for a heating device according to the invention functions as a thermal fuse. A heater is located on a support. In spatial proximity and with heat conduction to the heater are provided solder contacts with electrical leads to the support. A metallic connection bridge is firmly soldered to the solder contacts and the position thereof with respect to said contacts is such that in the use state on softening the solder connection at the solder contacts the connection bridge is separated by gravity and drops off. In this way the electrical connection from the heater to a electrical supply is separated.
Abstract:
A circuit (1) includes a plate-shaped substrate (2), a thick-film conductor array (8) having first contact parts (11), with which second contact parts (13) of connecting leads (15) are connected two-dimensionally by a compression bond. The second contact parts (13) are configured tape-like by compression from a copper strand. An additional, non-conducting positional seal (30) of a potting compound (31) positively locates the connecting leads (15) in position with respect to the substrate (2), as a result of which very high currents can be handled at very high operating temperatures by simple means.
Abstract:
A liquid pump has a rotor in a pump housing which has a pump chamber, a pump base, a pump-chamber wall and a cover. The rotor rotates just above the pump base, the pump-chamber wall being provided around the outside of and slightly spaced apart from the rotor and having a heating means thereon. An inlet to the rotor is provided centrally in the axial direction towards the rotor and an outlet from the pump housing is provided externally at the periphery of the pump-chamber wall. Blade-like guiding elements which are integrally injection-moulded thereon are arranged on the pump base, radially outside the impeller.
Abstract:
A radial pump for water has a drive motor, a pump chamber and an impeller revolving in the pump chamber. The impeller has a plurality of impeller blades which are designed, at least in regions, to be elastic and have a fixed mounting arranged in a region located near the impeller axis of rotation. They can bend elastically radially outward from this fixed mounting counter to a spring force.
Abstract:
The invention in one embodiment relates to a method for operating a washing machine having a heating unit, wherein the heating unit comprises a carrier and at least one planar heating element disposed thereon. At least one first heating element is attached to the carrier in a planar manner, wherein the carrier has a recess extending in the longitudinal direction in the center region. The washing machine has a washing machine barrel and a drum therein, wherein the heating unit is displaced at the bottom in the washing machine barrel outside of the drum. A heating element is provided on the outside of the carrier in the region of the recess in the region along an apex, or along an apex of the recess, wherein only said heating element is operated in the region of the recess for creating steam in the washing machine.

Abstract:
A steam generator for cooking devices has a vessel and a heating device. Water to be evaporated is contained within a free volume of an inner chamber of the vessel, which forms a water-guiding region. This water is heated through a heating device at least up to boiling temperature, whereby steam is generated that flows along a steam-guiding region of the vessel. The heating device is a thick-film heating device applied to the surface area of the vessel on the water-guiding region. Both the water and the steam flowing past cool the heating device as the water level drops.
