Definitions
- the present invention relates to a refrigerator with an inner lining and / or an inner door and a method for their preparation.
- the housing of a refrigerator and its door usually has a multi-layered structure, with a solid outer skin, a deep drawn from a plastic plate one-piece serving as inner lining or inner door inner container and an insulating layer which fills a gap between the inner container and the outer skin.
- the production of the inner container by deep drawing is simple and inexpensive, but the dimensions of the container thus manufactured can vary quite considerably compared to other production techniques. This can lead to problems when other parts with tight tolerances must be mounted in or on the container.
- EP 0 535 520 A1 describes an inner container of a refrigeration device in which an insert part is held in a form-fitting manner in a recess of the container wall. The anchoring of the insert in the container wall takes place during deep drawing by a
- the manufacturing tolerances for deep drawing are quite large. It may easily be the case that the board in the vicinity of the insert does not exactly lie against the wall surface of the drawing core, so that the finished container wall is recessed in the vicinity of the insert. It is difficult to make sure that the board, when deep drawing, is located in the space between the wall surface of the board
- the object of the invention is to provide a refrigeration device with a deep-drawn inner lining and / or a deep-drawn inner door and a method for its production, which facilitate the installation of mounting parts on the inner lining or the inner door with small tolerances.
- the object is achieved by a refrigeration device with the features of claim 1.
- the insert from the recess at least up to a flush with the surface surrounding a wall surface of the Inner lining or the inner door extends, the insert itself can serve as a stop for the positioning of a fixture. Since the positions of the inserts with respect to a deep-drawn core used for manufacturing the inner panel or the inner door are defined more accurately than the surrounding areas of the panel or door wall, a fitting can be reliably mounted in use of the inserts as a stop exactly.
- the insert is above the flush level.
- An insert may then be mounted adjacent to a projecting over the surrounding surface of a cladding or door wall stop surface of the insert.
- the insert may conveniently be provided with a wall of the inner lining or the inner door embraced spring.
- this spring may also be provided on the insert a groove, engages the cladding wall or the door wall.
- the width of the groove should at least equal the thickness of the inner door wall or the inner lining wall in the environment be the depression. Also, a cross-section of the groove which is widespread toward an open side facilitates the penetration of the wall material.
- the groove may be expediently limited on one side by a flush with the surrounding surface of the inner door wall or the inner lining wall circumferential flange.
- an inner lining or an inner door of the type described above is obtained by the insert is attached to a flat surface of the draw core adjacent or in a recess of the draw core engaging the draw core, a circuit board is pulled from a plastic material on the draw core to to shape the inner lining or the inner door, remove the fastening of the insert on the drawing core and then remove the inner lining or the inner door together with the enclosed insert from the drawing core.
- FIG. 1 to 4 each show a partial section through an insert core carrying a draw core and the insert part enclosing and on the pull core wall of a refrigerator interior lining.
- Fig. 5 is a schematic perspective view of an exercise for the
- Invention usable core before a deep drawing process
- Fig. 6 shows the same drawing core after the deep drawing process.
- Fig. 1 shows a section through a portion of a wall 1 of a refrigeration device inner container made of thermoformable plastic, mounted on a pulling core 2. On a displaceable in a bore 3 of the pulling core 2 holder 4, an insert 5 is attached. That around - A -
- an axis L-1 rotationally symmetrical insert part 5 running in the sectional plane has approximately the shape of an upside-down cup whose edge 6 is pressed by the holder 4 against the wall surface 7 of the pull core surrounding the bore 3.
- the wall surface 7 is - at least in the environment shown in the figure of the bore 3 - flat.
- Fig. 2 shows a section through an inner container wall 1, a pulling core 2 and a fitting of a displaceable holder 4 on the wall surface 7 of the pulling core 2 fitting insert 5 according to a second embodiment of the invention.
- a circumferential groove 13 is formed on the circumferential side wall 11 of the cup-shaped insert 5 to a distance from both the edge 6 and the cup bottom 10.
- the groove 13 has a rounded cross section, and its width is greater than its depth, so that the wall 1 can easily completely fill the cross section of the groove 13.
- the side wall 11 has a curved portion 14 to which the wall 1 can nestle over the entire surface, so that not, as shown in Figure 1, between the wall 1 and the edge 6, a gap 15 may arise. in which hard to remove impurities can collect.
- the circumferential side wall 11 carries on the one hand a flush on the wall surface 7 adjacent peripheral flange 16 and on the other hand, spaced from the flange 16 by a groove 17, a circumferential rib 18.
- the groove 17 has in its entrance region a width b, the larger is as the thickness d of the wall 1 in the vicinity of the insert 5.
- the wall 1 snuggles against the rib 18 and penetrates into the groove 17, so that the rib 18 acts as a spring, which in engages a groove formed during deep drawing of the wall 1, and thus the insert 5 anchored positively. It is not necessary that the material of the wall 1 penetrates into the groove 17 narrowing towards its bottom to the bottom, since a gap 15 remaining after deep drawing is shielded by the flange 16 against the interior of the container and therefore no contamination can collect.
- the insert 5 in the embodiment of Figure 4 differs from that of Figure 3 by the absence of the flange 16. instead, the side wall 11 is over the
- Wall surface 7 also extended by a cylindrical portion 20 which in a
- Container forms the end face 19 of the extension portion 20 or the correspondingly extended pin 8, a stop surface on which any built-in parts can be accurately placed, regardless of how exactly during deep drawing the wall 1 to the
- Wall surface 7 of the pull core 2 has created.
- FIG. 5 shows a perspective schematic view of a pulling core 2 which is suitable for producing an inner container for a refrigerating appliance with inserts 5 anchored in the wall according to the embodiment of FIG. 4.
- a pulling core 2 which is suitable for producing an inner container for a refrigerating appliance with inserts 5 anchored in the wall according to the embodiment of FIG. 4.
- four inserts 5 are complained.
- the pull core 2 retractable elements 22.
- the holder 4 and the retractable elements 22 are retracted into the interior of the pulling core, as shown in Fig.
