Benefits of technology

[0011]The present invention recognizes that it is desirable to provide a steam generating function while also minimizing additional parts and manufacturing costs. The present invention recognizes that important benefits, such as reducing costs, can be provided over the conventional devices by...

Problems solved by technology

Conventionally, water level sensors have not been adequate to closely and accurately control the water level in such a limited and sensitive range.
The present invention recognizes that such analog pressure sensors generally are not highly reliable devices for providing accurate and repeatable water levels, and hence, the conventional pressure sensors cannot maintain a reliable and accurate water level during a steam generation cycle.
Also, these conventional sensors commonly require the tub to be modified to include a penetration of t...

Abstract

A household appliance includes a housing having a door formed in a front panel thereof for accessing an interior of the housing, a tub disposed inside the housing for containing a liquid, the tub having an inner surface and an outer surface, and a steam generator. The steam generator includes a heating element inside the tub, and a liquid level sensor on the outer surface of the tub, the liquid level sensor detecting a level of the liquid inside the tub, wherein the liquid level sensor includes a non-contacting sensor that detects the level of the liquid without directly contacting the liquid.

Description

FIELD OF THE INVENTION[0001]The present invention is directed toward a domestic household appliance, and more specifically, toward a steam generator for a domestic household appliance.BACKGROUND OF THE INVENTION[0002]A household appliance, such as a front-loading clothes washer, includes a housing having a door providing access to a washing unit in the interior of the appliance housing. The washing unit includes a watertight tub for holding washing / rinsing liquid. A cylindrical washing drum is rotatably mounted inside the tub. In operation, clothes or laundry are inserted into the washer through the door and placed in the rotating washing drum inside the tub. In a washing cycle, the household appliance wets the laundry to be washed with washing liquid and mechanically moves the laundry to release contaminants from the laundry. In a rinsing cycle, the household appliance wets the laundry to be rinsed with rinsing liquid and mechanically moves the laundry to release the residual washi...
