Embodiment Construction

[0027] A household appliance 1, in particular a washer-dryer, comprises a cabinet 2 in which heated objects such as clothes are placed, a magnetron 4 for generating microwaves, and a magnetron 4 for feeding the generated microwaves into said cabinet A waveguide, a detector 5 connected to the waveguide 3 for detecting arc formation in the box 2, and a control unit 6.

[0028] The waveguide 3 and the arc detector comprise a slot 10 . The arc detector 5 is connected to the waveguide 3 in such a way that the formed slots 10 coincide and a signal is taken from the waveguide into the arc detector 5, said signal being representative of the field inside the waveguide.

[0029] The arc detector 5 also includes an antenna 7 for capturing signals, a filtering device 9 for filtering interference on the antenna 7, said filtering device preferably comprising a capacitor 12 and / or a ferrite component 13, a A microwave diode 8 for conditioning the electrical signal and a housing 11 for keepi...

Abstract

A household appliance ( 1 ) e.g a washer-dryer, comprises an enclosure ( 2 ) into which objects to be heated are placed, a magnetron ( 4 ) for generating microwaves, a waveguide ( 3 ) for feeding the generated microwave into the enclosure, an arc detector ( 5 ) coupled to the waveguide ( 3 ) for detecting the arcing within the enclosure ( 2 ) and a control unit ( 6 ).

Description

technical field [0001] The invention relates to a household appliance, in particular to a washing machine / dryer which safely uses microwave heating. Background technique [0002] Domestic devices using microwave energy for heating objects are known in the prior art, for example heating silk fabrics in dryers. The main disadvantage of heating with microwave energy is the generation of arcing, which is the phenomenon of electrical breakdown between two metal conductors, such as metal zippers, metal buttons, small metal objects that clothing may have. Arcing may cause objects to melt or burn. Research has been carried out to prevent arcing around metal substrates in enclosures to which microwave fields are applied. [0003] The main feature of US5325600 is a UV tube detector placed near the clothes, which is used to detect the condition of the resonant arc, but the detection and installation in the rotating washing drum is not an easy method, and it causes many structural pro...
