Flange assembly for securing a heating device to a fluid container

Abstract

The present invention relates to a flange assembly for holding a heating device to a fluid container of an appliance accommodating a fluid to be heated, in particular a domestic appliance, comprising a flange unit arranged for being mounted to an opening of the fluid container by at least one fixing unit and having a non-sealing and a sealing and attachment position, wherein the flange unit is reversibly moveable from the non-sealing to the sealing and attachment position by means of the fixing unit for being configured to engage the opening of the fluid container in the sealing and attachment position, wherein the flange unit comprises a sealing element and a tensioning element, wherein the sealing element and the tensioning element are moveable relative to each other in an axial direction by means of the fixing unit such that the sealing element and the tensioning element can be pressed against each other, wherein the sealing element and the tensioning element are, in the sealing and attachment position, arranged to provide a sealing in a sealing direction perpendicular to the axial direction, wherein the sealing element and/or the tensioning element of the flange unit comprise at least one tapered portion, wherein the tapered portion is arranged such that the relative movement of the sealing element and the tensioning element in the axial direction causes a predefined displacement of the tapered portion in the sealing direction. The invention further relates to a heating system including the flange assembly according to the present invention.
