Definitions

• the invention relates to a refrigerator with a body and at least one door, which together define a heat-insulated interior.
• Front plate made of ferromagnetic material provided on the back of a heating tube, which is acted upon to prevent condensation of the end plate with hot gas.
• heating wires may be arranged in the frame area. They are partly foamed up when filling the double wall of the carcass.
• interchangeable heating wires have been proposed, which are inserted into one of the support of the sealing profile on the closing edge of the door serving hollow profile of the body.
• Cooling or freezing appliances in which two doors close a contiguous interior, are becoming increasingly popular.
• the plurality of doors is not only practical when opening the device, but also has a favorable effect on the
• a refrigerator with a body and at least one door, which together define a heat-insulating interior and a door-facing frame of the body is provided with an electric frame heater, the frame heating comprises at least one Peltier element ,
• the advantage of the Peltier element in relation to the heating tube is that it is supplied with electricity and therefore it is just as easy to install in the frame area as a heating wire. Compared to the heating wire, however, it shows a much better energy balance:
• a Peltier element is an electrical component based on the Peltier effect named after Jean Peltier.
• a Peltier element usually consists of two thin ceramic plates between which series-connected, differently doped semiconductors are arranged so that in the vicinity of the first ceramic plate are all semiconductor boundary layers at which the current passes from a semiconductor of a first doping type in a semiconductor of the second doping type while the barrier layers, at which a current transition from a semiconductor of the second doping type to one of the first type takes place, are adjacent to the second ceramic plate.
• the fact that at a current flow through the semiconductor heat is conveyed from one ceramic plate to another, so that depending on the current direction, one plate cools and the other heated, called the Peltier effect.
• This heat transfer from plate to plate which results in addition to the Joule heat flow in the Peltier element, improves the energy balance of the Peltier element relative to the heating wire, in which only Joule heat is released.
• the interior of the refrigerator is divided by a separating body in two closable by each door zones, and the Peltier element is arranged in the separating body, because in such a separating body, the attachment of a heating tube is particularly difficult.
• the separator may be a continuous partition between the two zones, in which case the two zones may be operated at different storage temperatures.
• the separator may also merely have the form of a bar which forms part of the frame of the body and behind which the two zones are interconnected.
• the invention provides that the separating body together with at least one the doors is movable.
• the separating body is articulated on a side wall of the body.
• This embodiment is characterized in that the separating body can be mounted with the usual in refrigeration equipment hinges with which the doors are attached to the body. These consist mostly of a bearing pin bearing arm which is fixed to the frame, and a matching bearing pin sleeve which is to be attached to the door or on the separating body.
• the separating body like the doors, can optionally have a right or left stop.
• the separating body is hinged to one of the doors.
• This embodiment variant is particularly suitable for refrigerators with side by side instead of superimposed doors.
• the separating body should in this case be pivotable about an axis which runs parallel to one of the mutually facing edges of the doors.
• FIG. 1 shows a perspective view of a two-door refrigeration device according to the present invention, in which both doors are open;
• Fig. 2 is a perspective view of the same refrigerator with only one open door
• FIG 3 shows a vertical section through the separating body of the refrigerating appliance of Figures 1 and 2.
• FIG. 4 shows a perspective view of a second embodiment of a refrigeration device according to the invention
• FIG. 5 shows a horizontal partial section through a hinge connection between separating body and door of the refrigeration device from FIG. 4.
• the reference numeral 1 designates a refrigerator according to the invention.
• the perspective view shows the body 2 of the refrigerator 1 with hinged thereto, shown in the open position, superimposed doors 3a and 3b.
• the doors 3a and 3b are hinged about 10, 11 with a frame 6 as Front of the carcass 2 connected.
• Each door 3a, 3b is provided on the inside with a circumferential elastic magnetic profile seal 5.
• those three which are visible in the figure, are in the closed position of the doors 3a, 3b on the frame 6 of the body.
• the fourth strands of both doors 3a, 3b adhere magnetically in the position of Fig.
• a bar-shaped separating body 9 which is pivotally suspended on the adjacent hinges 11 of the two doors 3a, 3b.
• the doors 3a, 3b and the separating body 9 have the same pivot axis and perform the same pivoting movement when opening and closing the doors 3a and 3b. In the closed position of the doors 3a, 3b, the separating body 9 dips into a cooling space 4 of the body 2.
• the doors 3a and 3b can be opened together, so that the cooling space 4 is easily accessible.
• the lateral flanks of the doors are provided with an undercut 12. This extends over the entire height of the doors 3a, 3b, so that they can be grasped at any height; In particular, it is possible to simultaneously attack with one hand on both doors to open them.
• FIG. 2 shows a perspective view of the refrigeration device 1 with open upper door 3a and closed lower door 3b.
• the other door 3b prevents the partition 9 therefrom
• the partial opening of the refrigerator reduces on the one hand the loss of cold in the interior 4 and on the other hand, the relatively large force that the user must spend when opening a large refrigerator door.
• the separating body 9 consists of a cuboid body of heat-insulating material, in which a ferromag netic plate 13 is embedded, to which the magnetic seals 5 of the doors 3 a, 3 b adhere.
• the plate 13 extends in the vertical over the entire space between the seals 5 of the two doors, can penetrate into the moist ambient air, but only over part of the width of the seals. 5
• a Peltier element 14 is housed, which is here in a conventional manner with two ceramic plates 15, 16 and between these a plurality of differently doped semiconductor pieces 17, 18 is shown.
• One of the ceramic plates 15 touches the ferromag netic plate 13; the other 16 is located close to the rear side of the separating body 9.
• the plates 15, 16 are thus thermally coupled in each case closely to the surroundings or the cooling space 4.
• the Peltier element 14 is supplied with direct current so that the plate 15 acts as a warm and the plate 16 as a cold side; i.e. the heat output which the Peltier element 14 delivers to the ferromagnetic plate 13 is composed of Joule heat and heat released by the current flow in the element 14, which heat is conveyed out of the cooling space 4 by the Peltier effect.
• FIGS. 4 and 5 show a further embodiment of the invention.
• the perspective view shows the refrigerator 21 with body 22, doors 23a and 23b and a refrigerator 24.
• the doors 23a, 23b extend over the entire height of
• the door 23a is on the inside in the usual way with a circumferential elastic magnetic profile seal
• one of the four strands of the magnet profile seal 25 is replaced by an airtight hinge having a separating body in the form of a vertical one
• Power supply lines for the Peltier element are passed through the hinge 30 and the door 23b.
• a groove 40 is formed in each case, in which engage with the door closed 23b from the bottom or ceiling of the cooling space 24 projecting pins 41.
• FIG. 5 The position of the separating body 29 with the door 23b closed is shown in FIG. 5 as a filled outline with a closed contour.
• the pin 41 is located at one end of the groove 40, and the front of the partition body 29, in which the ferromagnetic plate is not shown, is flush with the front of the body 22, so that the magnetic profile seal 25 of the closed door 23 a on its whole Length is tight against either the body 22 or the separator body 29.
• the door 23a can be opened and closed in the usual way so that it need not be discussed further here.
• the door 23b is shown in the figure in two positions, as an empty outline in the closed position and as a filled outline in partially open position.
• the partition body 29 is entrained via the hinge 30, and the pin 41 slides along the groove 40, thereby pivoting the partition body 29.
• the area of the front side of the partition body 29 against which the magnet profile seal 25 abuts the door 23a pivots first into the interior of the refrigerator 24 and thus dissolves from the seal 25.
• the pivoting movement allows the separating body 29 to be preferred to the closed door 23a. In this case, the separating body 29 finally reaches a position shown as an empty solid outline in which a side edge 42 abuts against it on the rear side of the door 23b.
