Definitions
- the present invention relates to a refrigerator with a magnetically sealed door, especially a household fridge or freezer.
- Free-standing refrigerators generally have a housing with a metallic outer skin, the ferromagnetic material needed to close the magnetic seal can represent.
- the housing of outside is not exposed to any significant mechanical stress and for one User is not visible, but it is technically and economically interesting to do so To manufacture the housing as far as possible from plastic. In this case it turns out Problem of attaching the necessary for the closure of the magnetic seal ferromagnetic material in the area of the door opening.
- the object of the present invention is to provide a refrigeration device with an at least partially to create non-magnetic material existing housing, in which an am Frame of the housing attached ferromagnetic tape using a Magnetic seal allowed, and the risk of the tape coming off is eliminated.
- the belt has a plurality of Straps for anchoring in openings in the housing and at least as rigid is that when opening and closing the door, no magnetic forces act on it functionally relevant deformation of the belt.
- this is Tape preferably along a line of contact between the two shells arranged. So it can be used at the same time due to dimensional deviations to hide the gaps between the shells caused by the manufacture of the shells and so on to reduce the requirements for their manufacturing accuracy.
- the band can be fixedly mounted on a first of the two shells and together with this delimit one slot into one edge area of the other Shell engages.
- the edge region of the other shell preferably extends in the slot undulating, e.g. a wave crest for each band and a wave trough for that Band opposite region of the first shell can be facing.
- Such Waveform increases the stability of the other shell in one to the main plane of the Slit vertical direction; at the same time it increases the flexibility of the shell Depth direction of the slot. By compressing the selected border area in limited extent, an excess can be easily compensated.
- the Flexibility of the corrugated edge area can also be used to create a To achieve a sealing effect between the two shells.
- the band is a substantially L-shaped profile with a visible one Leg facing the magnetic seal and a hidden leg facing engages between the two shells.
- this profile shape contributes to the stiffness of the Tape, on the other hand it allows the attachment of the profile Arrange tabs on the concealed leg completely invisibly.
- Complementary to these tabs are expediently openings in one hidden leg facing surface of the frame is formed.
- the concealed leg can be attached facing surface of the frame a step along a connecting the openings Line may be provided as a stop when attaching the tape to the frame can serve for the tabs.
- second tabs are each formed on the longitudinal ends of the band. These second tabs can, like the first, be fastened in openings in the Serve housing; if the refrigerator includes several such tapes, is to Simplification of their assembly preferably provided that the second tabs at least one of these straps between the frame and other such straps intervention.
- Figure 1 shows a perspective view of a tape 1 made of ferromagnetic Material for use with a magnetic seal on the door of a refrigerator.
- the Band is made of sheet metal, preferably a painted or powder-coated sheet punched and bent into the shape of an L-shaped profile, with a first leg, which remains visible after the assembly of the tape 1 on the frame of a refrigerator and is therefore referred to as a visible leg 2, and a second leg which for The tape is anchored and is not visible after it has been installed on the refrigerator and is therefore referred to as a hidden leg 3.
- the hidden leg 3 several pairs of cuts are formed, and that of each pair of cuts limited tabs 4 are bent approximately vertically from the hidden leg 3.
- the band is bent by 180 ° and on the (not visible) back in led back.
- Figure 2 shows a partial section through the wall of a refrigerator in the area thereof Door opening.
- the housing comprises an inner and an outer shell 10 and 11 respectively inner shell 10 is in one piece here, e.g. by deep drawing, made of plastic; the outer shell, of which only one profile element acting as a frame in the figure 12 can be seen, can also consist of plastic.
- One of the two shells 10, 11 enclosed cavity 13 is with a heat insulating foam material filled.
- the profile element 12 has an when the door is open (from the right in the figure) visible frame surface 14, which is essentially perpendicular to the frame surface 14 into the interior of the cavity 13 extending contact surface 15 and one attached to it adjoining edge strips 16 parallel to the frame surface 14.
- the contact surface 15 has a plurality of slot-shaped openings through which, as in FIG recognize, in each case a tab 4 of the band 1 can be carried out. After performing the tab 4 is bent against the contact surface 15, so that the hidden leg 3 of the tape 1 rests on a surface of the contact surface 15 and on the opposite surface is held by the folded tab 4.
- the width of the contact surface 15 and the hidden leg 3 are each so dimensioned that after fastening the tape 1 to the profile element 12 Frame surface 14 and the visible leg 2 a uniform, flush surface form. If the door of the refrigerator (not shown in the figure) is closed, then there is a magnetic seal arranged on the edge of the door on the visible leg 2 on.
- the visible leg 2 and the edge strip 16 delimit a gap 17 in the one Edge area 18 of the inner shell 10 engages.
- This edge region 18 runs in the Area of the gap 17 undulating, with a first, flat groove 19, which is dimensioned, flush with the retracted lower edge of the visible leg 2 to record a first "wave crest" 20, which supports the visible leg 2, a "wave trough” 21 touching the edge strip 16 and a second "wave crest” 22, which forms the outer end of the edge region 18.
- This wavy course of the Edge area 18 gives it considerable strength against from the side of the door (from pressure exerted on the right in FIG. 2, at the same time it gives it a certain elasticity in Depth direction of the gap 17, which is a limited compression of the edge region 18th allows if this when assembling the refrigerator with the contact surface 15 or the concealed leg 3 mounted thereon comes into contact.
- an elastic Sealing tape 22 shown here as a thin-walled hose, may be arranged.
- Figure 3 shows a modification of the tape 1 of Figure 1.
- the hidden legs 3 are not flat, as shown in FIG. 1, but have a step 30 which extends along the same line as the bent tabs 4 are each connected to the concealed leg 3.
- Level 30 of the concealed leg corresponds to Level 30 of the concealed leg a complementary level 31 on that of the concealed Leg-facing contact surface 15.
- These complementary levels increase to one the stiffness of the band 1, on the other hand they facilitate the assembly of the band 1, since when it is introduced from the front of the refrigerator (from the right in FIG. 4) the tabs 4 of the hidden leg 3 meet the step 31 exactly when they aligned with the openings in the contact surface 15 corresponding to them.
- Volume 1 needs only slightly upwards after reaching this stop to be moved to its final installation position, in which the Tabs 4, as already described with reference to Figure 2, against the opposite Side of the contact surface can be bent.
- FIG. 5 shows a schematic front view of a refrigerator, in the area of his Door opening is equipped with the straps 1 described above.
- Figure 5 shows only that upper area of the door opening; the lower one is designed analogously.
- Bands 1 surround the Door opening on all four sides.
- the tabs 4 of all strips 1 each engage in openings in the surrounding profile elements 12, as in FIG Figure 2 and 4 shown in section.
- the terminal tabs 7 of the vertical bands 1 engage in corresponding openings in the upper, horizontal profile element 12.
- the terminal tabs 7 of the horizontal band 1 are between each vertical band 1 and the edge region 18 of the inner shell.
- the bands 1 thus form an uninterrupted, everywhere flush border of the Door opening of the refrigerator, on which the magnetic seal of the door on its entire Circumference can be tight.
