Definitions

• the present invention relates to a heat-insulating door for a household appliance, in particular for a refrigeration appliance.
• Such doors generally have a solid outer skin made up of a plurality of elements that defines an inner cavity filled with insulating material.
• a common design is to integrally form the front and side edges of a door of substantially flat parallelepiped shape of sheet metal, this connect along its vertical edges with a thermoformed inner wall and the open upper and lower sides of the thus obtained hollow body with the help of To seal plastic injection-molded closure parts. These end parts extend over the entire width of the door and therefore, if doors are to be manufactured in different widths, each must be provided to match a desired door width. For the production of each type of final part thus specific shapes are needed, which makes the entire manufacturing complex. Since the costs of the molds must be transferred to the devices manufactured therewith, doors in rarely requested widths are disproportionately expensive.
• Object of the present invention is therefore to provide a door for a household appliance, which can be made inexpensively and in a variety of formats with little specific tools.
• a door for a household appliance having an outer wall, an inner wall and upper and lower end parts, which together define a cavity, an upper side and / or a lower side of the door respectively by two Eckab gleichmaschine and arranged between the Eckab gleich kind intermediate piece is formed. Corner panels can be used consistently regardless of the width of different door models; a broadband customization is then possibly required at the intermediate piece. Since this intermediate piece can generally be of a simpler structure than the Eckab gleichmaschine, it can be provided inexpensively in different widths.
• a one-piece design of the intermediate piece with the outer wall is preferred because then the material of the inner wall with the door closed is not visible on the outside of the appliance.
• each preferably have a contact surface, which is intended for contact with the inner wall.
• the intermediate piece may expediently be extended by a web connecting the contact surfaces of two corner end parts in order to provide the inner wall with a contact surface over the entire length of its upper or lower edge.
• a hook may be formed at one end of the web, which engages in a recess of the EckabBankteils.
• each EckabBankteil has a bearing bush.
• a cable recess is expediently provided on at least one corner end part, in order to guide an electrical line from a body of the joint via a door hinge into the door.
• Outer wall and inner wall are preferably connected together along their vertical edges. Side flanks of the door are preferably through the Outside wall formed to keep the inner wall hidden with the door closed. A connection zone in which the vertical edges of the outer and inner walls are fastened together is expediently arranged on a rear side of the door.
• the outer wall has a at an edge of the door rear extending, cranked edge portion, and one of the EckabBankmaschinen is pushed onto the cranked edge portion.
• Fig. 1 is a schematic perspective view of a door according to the invention of a household appliance
• Fig. 2 is a right upper corner of the outer wall of the door, as seen from the
• FIG. 3 shows the corner of FIG. 2 with an attached corner end part
• Fig. 4 is a horizontal section through the corner of Fig. 3;
• FIG. 5 is a view similar to FIG. 2, according to a second embodiment
• FIG. 6 shows a view analogous to FIG. 3 according to the second embodiment
• Fig. 7 is a horizontal partial section through a EckabBankteil according to the second embodiment.
• Fig. 1 shows a perspective view from the front of a refrigerator door according to the present invention.
• An outer wall 1 cut from sheet metal extends over the front side 2, lateral flanks 3 as well as a predominant part of the upper side and the underside of the essentially flat rectangular door.
• the outer wall 1 is open can be realized in a simple manner by a rectangular piece is cut to the required dimensions of a sheet roll, at the four corners of the sheet metal piece thus obtained in each case a substantially rectangular piece is cut and thereby obtained at the upper and lower edge of the sheet sections are bent twice at right angles to form an intermediate piece 4 extending over the upper side of the door or an intermediate piece extending over the lower side and respectively an edge strip adjoining the intermediate piece on the rear side of the door, and the laterally projecting portions are bent over the lateral flanks 3 and also to form each one on the back cross border strips.
• EckverzBanker 5 fills the gaps between the folded lateral flanks 3 and the spacers 4 at the top and bottom of the door.
• the two upper EckabBankmaschine 5 are each formed a mirror image of each other, as well as the lower EckabBankmaschine 6.
• Upper and lower EckabBankmaschine can be identical to each other.
• Fig. 2 is a partial perspective view of the outer wall 1, seen from the back, in the region of its upper right corner.
• the edge strip 8 is planar in itself, the edge strip 7 has a curved course in order to form a vertical groove 9 open towards the inner cavity of the door.
• An adjacent to this groove 9 flat strip 10 of the outer wall 1 lies with the edge strip 8 in a same plane and is provided to attach thereto, not shown in the figure, the inner wall of the door, for example by gluing.
• Fig. 3 shows the same corner of the door, wherein the existing in Fig. 2 gap between the right flank 3 and the upper intermediate piece 4 is closed by a plugged-up from above Eckab gleichteil 5.
• the corner end part 5 comprises a horizontal base plate 11 in which a bearing bush 12 for receiving a hinge pin of a door hinge is recessed.
• a channel-shaped cable recess 13 which is provided to, if necessary, an electrical cable which extends from a device body, not shown, via the hinge into the interior of the door.
• a not visible in Fig. 3 groove is formed, which receives the designated in Fig. 2 with 14 upper edge of the edge 3, the edge strip 7 and a part of the front side 2 between the edge 3 and the intermediate piece 4 , An edge region of the base plate 11 rests on the intermediate piece 4.
• a to a rear, in Fig. 3 facing the viewer edge of the base plate 1 1 subsequent vertical wall 15 of the Eckab gleichteils 5 has a stepped course with an upper portion 16 which rests against the outside of the strip 10 and at an opposite end of the edge strip 8 and thus determines its orientation and its distance from the front 2 exactly.
• a lower portion 17 of the wall 15 forms a flush connection between the strip 10 and the edge strip 8 and, like this, can serve as a contact surface or bonding substrate for the inner wall.
• Fig. 4 is a horizontal section through the right upper corner of the door, in which the base plate 1 1 of the Eckab gleichteils 5 can be seen from below. It can be seen the cylindrical bushing 12, the subsequent thereto cable recess 13 and various the Eckab gleichteil 5 in itself and in particular the bearing bush 12 with respect to the base plate 1 1 stiffening ribs 18, 19. The rib 19 also extends over the inside of the wall 15th and forms a lateral stop for the intermediate piece 4 and the edge strip. 8
• the wall 20 engages in the groove 9 and thereby fixes the bending angles both between the front side 2, the side flank 3 and the edge strip 7 and between the front side 2, the intermediate piece 4 and the edge strip 8.
• Eckab gleichmaschine 5, 6 the Flank 3 bordering the top and bottom in the same way, a deformation of the edge 3 and in particular a bending outward is excluded under a prevailing during foaming of the inner cavity of the door pressure.
• Figures 5 and 6 show views similar to Figures 2 and 3 according to a second embodiment of the invention.
• the adjoining the intermediate piece 4 edge strip 8 carries here at the right and at the left end in each case one piece cut-out hook 21, which is provided to engage in a downwardly open recess 22 in the wall 15.
• the lower portion 17 of the wall 15 is reduced in width.
• the recess 22 can be seen, which receives the tip of the hook.
• the engagement of the hook 21 in the recess 22 stabilizes the connection of the Eckab gleichteils 5 with the outer wall 1 and also helps to absorb an occurring during foaming internal overpressure without deformation of the outer wall 1.
