Abstract: The present invention relates to a freezer, comprising a cooled interior and comprising a wall that surrounds the cooled interior at least in regions, and comprising a refrigeration circuit, wherein the wall is formed at least in part by a vacuum insulation body and/or by an insulation body which comprises or is made of polyurethane, in particular comprises or is made of polyurethane foam, or only by a vacuum insulation body or only by an insulation body which comprises or is made of polyurethane, in particular comprises or is made of polyurethane foam, and in that the refrigeration circuit comprises a refrigerant mixture.

Abstract: The present invention relates to a refrigerator unit and/or a freezer unit that has at least one voice control that comprises the following components: at least one detection device for speech recognition and at least one executing device that is configured to carry out at least one action of the refrigerator unit and/or freezer unit on the basis of speech recognized by the detection device.

Abstract: The invention relates to an apparatus for position detection having a magnet and a sensing element which has switched states or parameter values depending on the magnetic field generated by the magnet, with the apparatus furthermore having a means for influencing the magnetic field, with the means being made and arranged such that different switched states or parameter values of the sensing element can be generated in dependence on the position of the magnet, the sensing element and the means for influencing the magnetic field with respect to one another.

Abstract: The present invention relates to a refrigerator unit and/or freezer unit having a first electronic controller which controls a second electronic controller. In accordance with the invention, the first electronic controller transmits control signals to the second electronic controller by the selective switching of one or more mains half cycles of a mains voltage. The present invention furthermore comprises a corresponding method for the operation of a refrigerator unit and/or freezer unit.
