Abstract
Description
- The present invention relates to a household appliance and a method for detecting a thermal radiation.
- There are many household appliances having a fluid system containing running or stationary fluid or fluid mixtures, which mixtures may consist of different fluids or fluid(s) with solid and/or gaseous components, where it is necessary obtaining information about the temperature of said fluid or fluid mixture. Examples of such household appliances are washing machines, dish washers or laundry dryers with a condenser (condensation laundry dryers). The detected value or signal of the temperature of the fluid or fluid mixture may be used to control the operation of the household appliance. Further, the detected value of the temperature of the fluid may be displayed in order to inform the operator about the temperature of the fluid.
- In known household appliances the temperature of the fluid is detected by one or more sensor elements, which are in a direct contact with the fluid. For example, the sensor element may be a temperature sensitive electric or electronic element, in particular a temperature sensitive resistor or transistor element. Typically, the sensor element is an NTC (negative temperature coefficient) sensor.
- The sensor element is arranged in a fixed position within the fluid system. The sensor element requires electric connectors and wires in order to send signals out of the fluid system. The passageway for the wires through the wall of the fluid system risks a leakage in said wall. The sensor element and the wires have to be isolated. The temperature sensitive element reacts very slowly on a change of the temperature of the fluid.
- The
US 5,739,534 describes a system for detecting the presence of a fluid in a washing machine. The system comprises means for transmitting two or more infrared signals towards the fluid. The infrared signals have different wavelengths. Further, the system comprises means for detecting the infrared signals reflected on the fluid. By comparing the intensities of the infrared signals the presence of said fluid is determined. - In the
US 5,396,715 a microwave clothes dryer is disclosed. The dryer comprises an infrared sensor the occurrence of heating which might lead to an outbreak of a fire in the clothes. In order to avoid this, the dryer comprises means for introducing water into the chamber of the dryer to wet the clothes. - It is an object of the present invention to provide a household appliance having a fluid system with a new possibility for detecting a temperature of the fluid, which allows in particular a contact less detection of the temperature of the fluid.

- The detection of the thermal radiation of the fluid or fluid mixture can also be indirect in the sense that the thermal radiation of a body, wall or container such as a tub of a washing machine or dish washer or pipe being in thermal contact with the fluid or fluid mixture is detected.
- The term "thermal radiation" includes radiation, in particular electromagnetic radiation, of longer wavelength than visible light such as infrared radiation or radiation from the infrared spectrum as well as even longer wavelengths such as radiation from the microwave or even radio wavelength spectrum, e.g. wavelengths from typically 0.8 mm up to 1000 mm, in particular radiation in the wavelength range between 1 µm and 100 µm for temperatures in a temperature range up to about 100 °C.

For instance, the temperature of the fluid may be determined from the intensity of the thermal radiation.
- According to a preferred embodiment the fluid system comprises at least one transparent or transmissive device which is transmissive for infrared and/or thermal radiation, in particular thermal radiation as defined above, and arranged between the radiation detecting device or sensor element, in particular thermopile sensor element, and the fluid or fluid mixture.
