Definitions

  • the present invention relates to a multi-zone refrigerator and/or freezer, with an inner container, the inner container at least partially enclosing two zones, in particular temperature zones, the multi-zone refrigerator and/or freezer having thermal insulation in the form of a full vacuum insulation body.
  • Multi-zone refrigerators and/or freezers known from the prior art for example refrigerators and/or freezers with several zones at different temperatures, have one or more intermediate webs.
  • An intermediate web at least partially delimits one zone from another zone and is often provided with thermal insulation in order to make heat transfer from the warmer zone to the colder zone more difficult or prevent.
  • refrigerators and/or freezers from the prior art are designed in such a way that they have thermal insulation in the form of a foam, for example a polyurethane foam, i.e. a foam insulation.
  • Versions of multi-zone refrigerators and/or freezers with foam insulation are known, which have a one-piece inner container with a drawn intermediate web and an attached cross connector. Also known Versions with two drawn inner containers that are connected to each other by cross connectors. Also known are versions with a one-piece drawn inner container with an inserted insulated intermediate bar including a cross connector
  • the object of the present invention is to provide a simple multi-zone refrigerator and/or freezer with vacuum insulation, wherein the vacuum insulation should in particular have a low level of complexity.
  • the invention provides that the zone separation is achieved by an inserted intermediate web.
  • a full vacuum system is understood to mean thermal insulation that consists exclusively or predominantly of an evacuated area that is filled with a core material.
  • the boundary of this area can be formed, for example, by a vacuum-tight film and preferably by a high-barrier film.
  • the only thermal insulation that can be present is a film body that has an area surrounded by a vacuum-tight film in which there is a vacuum and in which a core material is arranged.
  • Foaming and/or vacuum insulation panels as thermal insulation or other thermal insulation apart from the full vacuum system between the inside and the outside of the container or device are preferably not provided.
  • a vacuum insulation body preferably comprises at least one vacuum-tight casing which surrounds at least one evacuated region, wherein one or more core materials, such as perlite, are preferably arranged in the evacuated region.
  • the intermediate web is connected to the inner container by a non-positive and/or positive connection.
  • the intermediate web has thermal insulation in the form of polyurethane foam and/or a vacuum insulation body, preferably in the form of a vacuum panel or a perlite vacuum body.
  • a cross connector is, for example, an element, in particular a metal element, on which the door seal of a door of the multi-zone refrigerator and/or freezer rests when the door is closed.
  • the refrigerator and/or freezer has a screw connection between the cross connector and a side wall of the inner container, which is preferably designed by means of an additional component, in particular with a metal plate, in particular in the front area of the refrigerator and/or freezer.
  • the screw connection by means of an additional component is preferably designed such that the additional component is screwed to the cross connector and/or to the intermediate web and to the inner container.
  • a hinge and/or a bearing component preferably a bearing block, for a door is arranged on the intermediate web, wherein the hinge and/or the bearing component preferably forms a connection between a cross connector and a side wall of the inner container.
  • the refrigerator and/or freezer or the inner container is completely insulated, preferably from an environment, with thermal insulation in the form of one or more full vacuum insulation bodies.
  • Complete insulation with thermal insulation in the form of one or more full vacuum insulation bodies preferably means that every thermal insulation in the refrigerator and/or freezer is thermal insulation in the form of a full vacuum insulation body.
  • the refrigerator and/or freezer has other types of thermal insulation, such as foam insulation. These other types can be located in particular in the interior of the refrigerator and/or freezer.
  • one zone has a temperature between -3 °C and 10 °C, preferably between 5 °C and 7 °C, and the other zone has a temperature between -30 °C and -18 °C.
  • the intermediate web has a receptacle which is designed to at least partially accommodate a component, in particular a lighting component, an operating element and/or a condensate pipe.
  • the intermediate web at least partially comprises one or more refrigeration components, in particular an evaporator, a refrigerant valve, an air duct and/or a fan.
  • one or more refrigeration components in particular an evaporator, a refrigerant valve, an air duct and/or a fan.
  • the multi-zone refrigerator and/or freezer with vacuum insulation i.e. with at least one vacuum insulation body
  • the intermediate web can serve as a holder for a cross connector.
  • the intermediate web can be connected to the inner container in various ways in order to ensure and/or increase housing stability.
  • a force-fitting and/or form-fitting connection to the inner container and/or a screw connection between a cross connector and a side wall of the inner container is conceivable.
  • the intermediate bar in combination with a side wall can serve as a mounting option for a hinge and/or a bearing block of an appliance door.
  • the thickness of the intermediate bar on the cross connector can depend on the type of refrigerator and/or freezer. In built-in appliances, the thickness of the intermediate bar is preferably in a certain range, for example due to hinges.
  • the intermediate bar preferably has a thickness between 90 mm and 130 mm, in particular between 100 mm and 120 mm.
  • a body 10 or a housing of a multi-zone refrigerator and/or freezer is shown.
  • the body 10 has an inner container into which an intermediate web 1 is inserted.
  • the body 10 is provided with thermal insulation in the form of one or more vacuum insulation bodies.
  • the intermediate web means that two zones, preferably temperature zones, in the body are at least partially separated from one another.
  • an inner container 2 is shown with an intermediate web 1 arranged thereon, the inner container 2 having a contour 3 which is designed in such a way that an intermediate web 1, which is inserted into the inner container 2, can form a positive connection with this contour and thereby on the Inner container 2 is attached.
  • the contour 3 is arranged in one piece on the inner container and includes projections extending into the interior of the inner container, for example in the form of two rails.
  • the inner container 2 is a deep-drawn part and the contour 3 was formed during deep-drawing.
  • the intermediate web 1 has contours corresponding to the projections or rails.
