Abstract

A refrigeration appliance, in particular a domestic refrigeration appliance, includes a storage chamber delimited by an inner container and a pressure sensor disposed outside the storage chamber. The pressure sensor communicates with the storage chamber by way of a connection housing anchored in an opening of a wall surface of the inner container. An exposed surface of the connection housing facing the storage chamber is flush with the surrounding wall surface.

First claim

1 . A refrigeration appliance or domestic refrigeration appliance, comprising:
an inner container having a wall surface and delimiting a storage chamber; a pressure sensor disposed outside said storage chamber; and a connection housing anchored in an opening formed in said wall surface of said inner container; said connection housing providing communication between said pressure sensor and said storage chamber; and said connection housing having an exposed surface facing said storage chamber and being flush with a surrounding part of said wall surface.

2 . The refrigeration appliance according to claim 1 , which further comprises a layer of insulation material surrounding said inner container, said pressure sensor being disposed outside said layer of insulation material.

3 . The refrigeration appliance according to claim 1 , which further comprises a deflectable membrane dividing said connection housing into a pressure sensor part and an inner container part.

4 . The refrigeration appliance according to claim 1 , wherein said inner container has a border area surrounding said opening and being sunk into said wall surface.

5 . The refrigeration appliance according to claim 4 , wherein said connection housing includes a cover, said exposed surface is part of said cover and said border area and said cover define a gap providing communication between said pressure sensor and said storage chamber.

6 . The refrigeration appliance according to claim 5 , which further comprises a layer of insulation material surrounding said inner container, said connection housing including a backing piece engaging in said layer of insulation material, and a pipe connected to said backing piece and communicating with said pressure sensor.

7 . The refrigeration appliance according to claim 6 , wherein said pipe emanating from said backing piece extends upwards.

8 . The refrigeration appliance according to claim 6 , wherein said backing piece has a nozzle, and an insertion cartridge fastens said pipe to said nozzle.

9 . The refrigeration appliance according to claim 1 , which further comprises a bayonet coupling anchoring said connection housing in said opening.

10 . The refrigeration appliance according to claim 9 , wherein:
said inner container has a border area surrounding said opening; said opening includes a circular central area; said connection housing includes a cylindrical pipe section extending through said circular central area; said bayonet coupling includes a crosspiece protruding radially outwardly from said pipe section and extending in a peripheral direction of said pipe section; and at least one protrusion is provided through which said crosspiece can be passed to overlap with said border area when said bayonet coupling is in a locked position.

11 . The refrigeration appliance according to claim 10 , wherein said crosspiece is one of at least two crosspieces of said bayonet coupling protruding radially outwardly from said cylindrical pipe section and being separated from each other by gaps in a peripheral direction, said crosspieces having different dimensions in at least one of a radial direction or a peripheral direction or said gaps having different dimensions in a peripheral direction.

12 . The refrigeration appliance according to claim 11 , wherein said at least one protrusion includes at least two protrusions in said opening, at least one of said at least two protrusions being dimensioned to only allow one of said two crosspieces through in a direction of a longitudinal axis of said pipe section.

13 . The refrigeration appliance according to claim 6 , wherein said inner container has an external side, and said backing piece has a peripheral apron being elastically deformed in contact with said external side of said inner container.
