Abstract

The invention relates to a refrigerator having two movably connected housing parts that delimit a heat-insulated interior and a seal member that is fastened to a first of the housing parts and contacts the other of the housing parts in an airtight manner in the closed disposition of both housing parts. A lifting element lifts the seal member from a contact surface on the second housing part to permit pressure compensation between the inner chamber and the surroundings of the refrigerator. The lifting element is at least in part formed by a thermally deformable material and, in a first shape thereof, it establishes a sealed contact between the seal member and the contact surface, and in a second state resulting from the effect of heat or cold, it lifts the seal member from the contact surface in order to ensure pressure compensation.
