Definitions

  • the present invention relates to a door, especially for a household appliance which is fitted with a heat-insulating glazing.
  • a refrigerator with an insulated glazed door is known, for example, from U.S. Pat. No. 5,622,414.
  • the door of this refrigerator is substantially constructed of two glass panels held at a fixed distance from one another by two spacers, of which the outer panel projects by a small distance over the inner panel in an edge zone in order to provide a working surface for a hinge for pivoting the door.
  • the spacer is also lengthened beyond the edge of the inner panel in order to form a contact surface to which a plate of the hinge can be screwed. Since the hinge plate and the spacer must generally be made of metal for reasons of mechanical stability, a poor thermal insulation action of the door is obtained in this edge zone. There is thus a risk that condensation will deposit externally on this poorly insulated area of the door which, if not removed, can result in damage.
  • condensation could certainly be avoided by electrical heating using heating wires attached to the surface of the outer glass panel but this type of heating increases both the manufacturing costs of the appliance and also, as a result of intensified heat input exactly at a weak point of the thermal insulation, the power consumption of the appliance during operation and thus its operating costs.
  • a heat-insulating door for a household appliance having the features of the preamble of claim 1 is known from U.S. Pat. No. 5,588,421.
  • This door comprises a frame made of sheet metal which ends on an outer side flush with a front glass plate and in which an opening is cut wherein a smaller inner plate is affixed.
  • This door is primarily described as a door for a baking oven but should also be suitable for refrigerators.
  • the problem would also arise here that the heat conduction of the frame adjacent to the cool zone of the refrigerator would result in the formation of condensation on the exposed outer surfaces of the frame.
  • the poor thermal insulation effect of the frame would also result in a high energy consumption of the refrigerator.
  • the object is solved by a door having the features of claim 1 .
  • the frame does not extend over the edge of the outer pane so that it is not visible for an observer looking at the door from the front and gives the impression that the door is formed substantially by the outer pane.
  • the frame is preferably connected to the outer frame by gluing.
  • the outer pane is provided with opaque decoration at least in its edge area.
  • the decoration is preferably attached to the surface of the outer pane facing the inner pane.
  • a gap between the inner pane and the frame is preferably filled by a compressible sealing strip.
  • this sealing strip is attached between the inner pane and the inner frame part.
  • the thermal insulation element is preferably a plastic profile element which engages in positive contact in grooves at least in the outer frame part.
  • the grooves are at least locally undercut.
  • a particularly high insulation effect can be achieved with a thermal insulation element embodied as a hollow profile.
  • a flexible sealing profile which is provided to abut in an airtight fashion against the body of the household appliance when a door mounted on a household appliance is closed and thus to seal its interior, is preferably retained in a groove of the frame which is bounded at least by the inner frame part and the thermal insulation element.
  • a good insulation effect with a small thickness of the door at the same time can be achieved if the inner frame part, the thermal insulation element and the outer frame part are adjacent to one another from inside to outside not or not only in the thickness direction of the door but primarily transverse thereto, in a plane parallel to the inner pane of the door.
  • FIG. 1 is a perspective view of a wine store cupboard as an example of a household appliance with a door according to the invention
  • FIG. 2 is a section through an edge region of the door according to a first embodiment
  • FIG. 3 is a section through an edge region of the door and parts of the refrigerator body adjacent thereto according to a second embodiment of the invention.
  • FIG. 1 shows a perspective view of a bottle store cupboard as an example of a refrigerator with a door according to the invention.
  • the body 1 of the bottle store cupboard can be free-standing or constructed as a built-in model as shown here. Whereas in most built-in refrigerators in the built-in state, the front of the door is covered by a furniture panel, the door 2 of the appliance shown here is provided to remain freely visible in the built-in state.
  • the outside of the door is formed by a glass panel 3 which is glued at its back to a frame 4 made of metal. Acting on the frame 4 are two hinge supports 5 fixedly connected to the body 1 of which only the upper one can be seen in the figure.
  • An inner glass panel 6 (see FIG. 2 or 3 ) whose edges are surrounded by the frame 4 forms an insulating glazing together with the outer glass panel 3 .
  • the interior of the body 1 is visible therethrough; disposed therein is a plurality of bottle carriers 7 , each formed by front and rear horizontal carriers 8 and cylindrical-segment-shaped shells 9 suspended between the carriers.
  • a handle 10 attached to the outer glass panel 3 is screwed in the frame 4 through two holes in the glass panel 3 .
  • FIG. 2 shows a section through an edge region of the door 2 according to a first embodiment of the invention.
  • the outer glass panel 3 is connected to the outer frame part 12 by means of an adhesive layer 11 .
  • the outer frame part 12 is joined together from four extruded profile pieces, e.g., of aluminium which each extend along an edge region of the outer panel 3 .
  • the edges of the outer glass panel 3 are in each case bordered by a projecting rib 13 of the outer frame part 12 which ends flush with the outside of the glass panel 3 and protects its edge from damage.
  • An aluminium cover profile 14 is placed on the edge of the glass panel 3 and the outer frame part 12 from outside.
  • the two legs of the cover profile 14 having an approximately U-shaped cross-section bear two flat, inwardly directed ribs 15 , 16 of which one 15 presses elastically against the outside of the glass panel 3 and the other 16 is clipped into a flat groove on the inside of the outer frame part 12 .
  • the inner glass panel 6 is connected at its edges to the inner frame part 19 by means of an adhesive layer 21 .
  • the inner glass panel 6 is thus connected rigidly to the outer glass panel 3 by means of the frame parts 12 , 19 and the webs 3 and the layer of air enclosed in the gap 22 located therebetween form an effective insulation over a large part of the surface of the door 2 .
  • the webs 18 are substantially responsible for the thermal insulation effect which, on the one hand as a result of their small cross-sectional area and on the other hand, as a result of the fact that they consist of a poorly heat-conducting plastic, present a considerable heat transfer resistance.
  • a further contribution to the insulation effect comes about because the inner frame part 19 and the outer frame part 12 are hollow profile elements in which heat transport is substantially only possible along the walls.
  • a flexible seal 23 which engages in a gap 24 defined by the webs 18 between the frame parts 12 , 19 and is anchored therein, and which is filled with ferromagnetic material in a fashion known per se on a side facing away from the anchoring on an opposing side so that it nestles tightly against the front of the body 1 as a result of magnetic force when the door is closed.
  • the inner frame part 19 shields the seal 23 from the interior of the refrigerator so that cold air can only penetrate from there in a narrow intermediate space 25 between the seal 23 and the inner frame part 19 to a small extent.
  • FIG. 3 shows a second embodiment of the edge region of a door according to the invention and a region of the refrigerator body 1 adjacent thereto.
  • the structure of the door comprising an outer glass panel 3 , an outer frame part 12 composed of aluminium hollow-profile elements which bears the outer glass panel 3 and a hinge, an inner glass panel 6 surrounded by the outer frame part 12 and an inner frame part 19 is the same as in the embodiment in FIG. 2 but in the embodiment in FIG. 3 the inner frame part 19 has no supporting function for the inner glass panel 6 but merely serves for thermal insulation.
  • the inner glass panel 3 is connected to the outer glass panel 3 by means of a spacer element 26 , which can comprise an aluminium profile for example, as is known from window construction for buildings, and which interconnects the two glass panels 3 , 6 hermetically by means of gluing or putty.
  • the two glass panels 3 , 6 and the spacer element 26 can be pre-assembled using technique known from insulated glass window construction and the intermediate space between the glass panels 3 , 6 can be filled with a known gas having a better insulation capacity than air.
  • an opaque decoration 27 is applied to the back of the outer glass panel 3 in an edge region, e.g. by screen printing, which decoration extends from the edge of the pane 3 inwards as far as over the spacer element 26 to conceal this and the frame 4 on the ready-mounted door.
  • the two frame parts 12 , 19 forming the frame 4 are rigidly connected by a plastic profile element, here in the form of a hollow profile 28 , which has ribs engaging in grooves 17 of the frame parts 12 , 19 in a form- and force-locking fashion.
  • the inner frame part 19 is separated from the inner glass panel 6 by a gap which is filled with a circumferential foam strand 29 .
  • the foam strand 29 has a plurality of easily deformable ribs 30 which nestle closely against the glass panel 6 .
  • the strand 29 is anchored on the inner frame part 19 by a projection 31 which engages in positive contact into an undercut groove of the frame part 19 .
  • a magnetic seal 23 which provides for an airtight connection of the door 2 to the front of the body 1 is anchored in a groove 32 which is formed on the one hand by the inner frame part 19 and on the other hand by a rib 33 which is thickened at the end and protrudes from the hollow profile 28 towards the body 1 .
  • the magnetic seal 23 has a flexible tongue 34 which, when the door 2 is closed, nestles against its back over the entire length of the outer frame part 12 and thus closes a cavity 35 between the rib 33 and the outer frame part 12 in an airtight fashion and thereby contributes additionally to the thermal insulating effect of the door in the area of the seal 23 .
  • the inner frame part 19 Since, in this embodiment, the inner frame part 19 has no supporting function and is exposed to no strong mechanical loadings, it can be executed as very thin walled which likewise improves its insulating effect or, instead of metal, it can be made of a comparatively better-insulating plastic material. Another possible modification is to construct the inner frame part 19 in one part with the plastic hollow profile 28 .
