  • Patent number: 7845198
    Abstract: An acceleration sensor for a household device which serves for leveling the appliance and also for weighing the material introduced into the appliance, for example on a laundry unit or crockery and furthermore, in particular for a linen treatment device, for monitoring imbalances. The sensor is based on the principle that a temperature profile, generated by a thermal source, for example, an immersion heater in a sealed chamber which contains a gas, undergoes a displacement as a result of the acceleration, which is measured by temperature sensors arranged on a flat plate.

  • Patent number: 7832236
    Abstract: A foam sensor of a drum washing machine is constructed such that a pair of temperature electrode terminals and a foam electrode terminal are supplied with electricity by a single connector, and thus is able to sense an electrical connection by a signal change of the temperature electrode terminals, in a case where electrical connection of the foam electrode terminal is cut off, thereby preventing a false sensing of foam generation caused by electrical short-circuiting of the foam electrode terminal. Furthermore, the foam electrode terminal is provided integral with the connector, and the temperature sensor portion has a thermistor for sensing a temperature of washing water and temperature electrode terminals inserted into the connector, the thermistor and the temperature electrode terminals being connected by a cord, which makes installation easier.

  • Publication number: 20080105001
    Abstract: A washing machine having a broadcasting receiver for providing various multimedia contents on the washing machine is disclosed. A broadcast signal reception module is provided in the washing machine, such as a washer or dryer, which is frequently used in the user's living space. Therefore, the washing machine can not only perform a washing operation, but also output a broadcast signal. In particular, the provision of the broadcast signal reception module in the washing machine enables reception of a mobile broadcast signal, as well as a fixed broadcast signal, thereby making it possible to provide more various multimedia contents through the washing machine. Therefore, it is possible to increase customer satisfaction with a multifunction-alization of the washing machine and thus use the washing machine more universally, resulting in an increase in the competitiveness of a product.

  • Patent number: 7296236
    Abstract: A universal controller is employed in a domestic appliance including a user interface. In order to determine the particular user interface utilized and, correspondingly, the available cycles, features and options of the appliance, a scan of a keypad matrix associated with the user interface is performed to determine the presence and/or absence of shorts used to reflect the existence of permanently closed keys of the matrix. In accordance with the invention, the shorts can be indicated individually, in sequence and/or in combination in order to indicate to the controller which firmware to execute for a particular user interface.
