Description

Refrigeration unit with pull-out shell

The present invention relates to a refrigerator, in particular a household refrigerator, with a body and a door surrounding a heat-insulated storage room, and a withdrawable from the storage room shell. Such trays are usually arranged one by one or several above one another in a lower region of the storage space, so that a user, in particular in the case of a refrigeration device standing on the floor, has to stoop to grab a handle of the tray and to pull out the tray. Most plastic shells are molded in one piece, and for reasons of stability, it is convenient to mount the handle near an edge of the shell where a front wall and a bottom plate of the shell meet. A low-grip handle on a shell located deep down in the storage room forces the user to stoop when pulling out the shell, which makes the use of the shell cumbersome. The object of the invention is to provide a refrigerator with a pull-out shell, which allows a user easier access to the shell.

Refrigeration appliance is understood in particular to mean a household refrigerating appliance, that is to say a refrigeration appliance which is used for domestic management, such as, for example, a refrigerator or a refrigerated freezer combination. The refrigeration device can be a no-frost refrigeration device, in which cold air is supplied to a refrigerator for cooling its storage space

Evaporator chamber is blown into the storage room.

The task with a refrigerator, in particular a household refrigerator, with a body and a door that surrounds a heat-insulated storage room, with a retractable from the storage room shell and with a shell in an inserted into the storage room position overlapping plate solved that a Handle bar extends to a front wall of the shell at least to a front edge of the plate. In particular, the handle bar is pulled up to the front edge of the plate. By this arrangement, the handle bar is accessible from above, from exactly the same direction from which the user will then access the contents of the upwardly open shell. Due to the high placement of the handle bar is the extent to which the user if necessary, to stoop to access the shell, reduced. Preferably, the shell is only partially covered in the inserted into the storage space position of the plate and protrudes at least with its handle over the front edge of the plate.

The handle bar is particularly useful in the case of a shell, which is guided in the body on telescopic rails friction and therefore requires only relatively small forces to wind up.

The handle bar is preferably designed as a separate from the front wall of the shell and attached to the upper edge element. As a result, the handle bar can be easily manufactured with a significantly higher bending strength than the front wall. By the handle bar thus making a significant contribution to a trouble-free operation

required rigidity of the shell, the walls of the shell can be designed to save costs with a relatively small wall thickness. For simplicity, the handle bar is preferably attached to the upper edge of the front wall.

On the one hand due to the high load capacity, on the other hand, but also for creative reasons, the handle bar is preferably made of metal.

The attached handle bar allows the front wall on a large area transparent and preferably even form, so that the contents of the shell is clearly visible over a large area, without the shell must be pulled out. A leading edge of the plate covering the shell in the retracted position may also be reinforced by an attached profile. The uniform

Appearance because of this profile is preferably at least superficially made of the same material as the handle. By being closely adjacent to each other in the retracted position of the shell, they may appear to the viewer as a unit.

The profile mounted on the plate preferably comprises a downwardly directed web. This contributes significantly to the stiffening effect of the profile, on the one hand Others, as will become clear later, interact with the handle bar to complete the shell in the retracted position.

To ensure easy handling, preferably an engagement recess between the handle bar and a front edge of the plate is kept free. In this

Engaging recess can engage the user's fingers from above to pack and pull the handle bar on the back.

The engagement recess may extend over the entire width of the shell; This allows in particular an inexpensive production of the handle bar and the profile by extrusion or extrusion.

Alternatively, the engagement recess may be flanked on both sides by projections of the handle bar. By forming a labyrinth seal with the leading edge of the panel, they contribute to the completion of the interior of the shell from the surrounding storage space and

in particular for limiting the air exchange between the shell and the surrounding storage space.

Preferably, the handle bar comprises a in the retracted position under the plate engaging web. Such a bridge can make a significant contribution to the rigidity of the handle bar with low material costs. In addition, it prevents objects from falling through a gap between the handle bar and the front edge of the plate into the shell.

According to a preferred development, the shell can be closed tightly by an overlying lid. So can evaporate from stored in the shell refrigerated goods

Moisture in the shell are held, which limits the further evaporation of the refrigerated goods and improves its shelf life.

So that the lid remains when removing the shell in the storage room, it is expediently suspended from the plate.

Also, a web of the handle, in particular the above-mentioned, in the retracted position under the plate engaging web can form a support for the lid. The lid is conveniently height adjustable so that when a tight seal of the tray is not desired, it can be kept spaced therefrom.

A slider for adjusting the height of the lid may conveniently be adjustably mounted along a front edge of the plate.

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:

Plate of Fig. 2;

Household freezer. Fig. 1 shows a schematic cross section through a no-frost household refrigeration appliance with a body 1 and a door 2 shown here open, which surround an interior. The interior is divided by a mounted under the ceiling of the body 1 shell 3 in an evaporator chamber 4 and a storage space 5 for refrigerated goods. The storage space 5 is divided by a horizontal plate 6, which may be formed in particular as a glass plate to form near the bottom of a compartment 7 for a removable tray 14.

In the evaporator chamber 4, an evaporator 8 and a fan 9 are housed in a conventional manner. When the fan 9 is in operation, it sucks air from the storage room 5 via openings 10 at a front edge of the shell 3 in the

Evaporator chamber 4, where it cools in contact with the evaporator 8, and pushes the cooled air into a distribution line 1 1, which extends in the rear wall of the body 1 downwards. Several outlet openings 12 of the distribution line 1 1 open in

different heights in the storage room 5; a bottom outlet opening 13 opens below the plate 6 in the compartment 7. The contents of the shell 14 is substantially cooled by an air flow from the outlet opening 13, which passes through a channel 16, which closes between the plate 6 and a shell 14 Lid 15 extends.

A similar arrangement is also feasible in a coldwall refrigeration device by a stream of air cooled by an evaporator embedded in the rear wall of the cabinet through a channel between a lid of a withdrawable tray and a tray

overlying plate is performed.

The guided on telescopic rails 19 shell 14 is shown in Fig. 1 in two positions, for a dashed outline in an inserted into the compartment 7

Stop position and on the other, with solid lines, in one

pulled out stop position in which the entire shell 14 before the

Front edge of the plate 6 is located.

A plastic one-piece or multi-part injection molded body of the

Substantially cuboidal shell 14 comprises a horizontal bottom plate 20, a front wall 21, a rear wall 22 which is slightly lower than the front wall 21, and the walls 21, 22 connecting side walls 23, a uniformly to the rear wall 22 down sloping top edge 24 and one respectively one of the telescopic rails 19 have receiving level 25. At least the front wall 21 is crystal clear and even, so that the contents of the shell 14 can be seen without the shell 14

must be pulled out.

On the upper edge of the front wall 21, a stiffening element 26 is attached. The stiffening element 26 can be extruded profile with a U-shaped portion, the downwardly open groove frictionally fitted on the front wall 21, is latched or glued to it, and a substantially horizontal, flush with the upper edges 24 above the bottom plate 20 extending web 27 and the ends of the groove closing head pieces can be realized at both ends of the profile; Also conceivable is a one-piece production of the entire stiffening element 26 including the head pieces by injection molding.

In the retracted stop position of the shell 14, the stiffening element 26, together with the front edge of the plate 6 defines an upwardly open groove 28, in which a user can engage from above to pull out the shell 14. The web 27, which protrudes counter to the then acting tensile direction, gives the stiffening element 26 considerable bending stiffness, so that the tensile force is distributed over the entire width of the front wall 21 into the main body of the shell 14. A lid 15 is suspended from the plate 6 via interlocking hooks 33, 34 and eyelets 29, 30 which are respectively mounted in the vicinity of the four corners of the plate 6 and the lid 15. The eyelets 29, 30 each have a vertical slot 31, in which the hooks 33, 34 engage with vertical play, so that the lid 15 is indeed vertical, but not horizontally movable. The lid 15 is in Fig. 1 in a

Rest position shown in which he is not supported by the shell 14 but only held on the plate 6. The hooks 33, 34 are located at the lower ends of the slots 31, respectively. As you can see, this rest position is lower than the course of the upper edge 24 of the side walls 23 of the shell 14 in the retracted stop position, and also the inclination of the lid 15 is stronger in the rest position than that of the edges 24. Since the front edge 17 of Cover 15 is higher than the upper edge of the rear wall 22, the shell 14 slides when pushing into the compartment 7 easily under the lid 15 and only shortly before reaching the inserted stop position so that the lid 15 to touch and lift it. Since the inclination of the lid 15 stronger than that of the Edges 24, initially touched only the upper edge of the rear wall 22, the lid 15, and with the progression of the inward movement of the shell 14, the lid 15 is first pivoted. Only when this is raised in the rear area so that its inclination corresponds to that of the upper edges 24 of the side walls 23, there is a flat contact between the edges 24 and the lid 15. If the

Pull-out box has reached its inserted stop position, touch the

Upper edges of the walls 22, 23 of the shell 14 and a rear portion of the web 27, the lid 15, so that the interior of the shell is substantially airtight and in any case closed zugdicht. Thus, a higher humidity can be maintained in the shell 14 by evaporation from refrigerated goods contained therein than in the surrounding storage space 5, the air constantly loses moisture by contact with the evaporator 8. This reduces the desiccation of the refrigerated goods and thereby improves its shelf life. Fig. 3 illustrates this fact with reference to an enlarged section through the front upper edge of the shell 14, the lid 15 and the plate 6. It can be seen here that the front edge of the plate 6 is reinforced by an attached profile 35, which as the stiffening element 26 is made of aluminum and / or a

Surface treatment identical to that of the stiffening element 26 has. The front eyelets 29 are attached to the ends of the profile 35. The rear eyelets 30, which are not visible in FIG. 3, form part of a profile 18 attached to the trailing edge of the plate 6. A rib 36 projects obliquely downwards from a main part of the profile 35 embracing the front edge of the plate 6 and ends just above the web 27 A flat edge region 37 of the lid 15 lies behind the rib 36 on the web 27, so that a possible vertical movement of the lid 15 is not hindered by the rib 36.

The edge region 37 extends on all four sides of the lid 15 about a central region 38. While the edge region 37 is planar in order to rest tightly on the web 27 or the upper edges 24 of the side walls 23 and the rear wall 22, the central region 38 arched to increase the flexural rigidity of the lid 15. FIG. 4 shows a second embodiment of plate 6, cover 15 and shell 14 in a perspective view analogous to FIG. 2. The most striking difference from the representation of FIG. 2 is a slider 39 which is latched onto the profile stiffening the plate 6 35. Fig. 5 shows this slider 39 in a perspective view obliquely from below, together with a piece of the flat front edge portion 37 of the lid 15, but omitting the plate 6 and the profile 35. The slider 39 comprises three one-piece, similar to an asymmetrical U Profile, rectangularly connected wall elements 40, 41, 42 which engage in the finished assembled state of Fig. 4, the profile 35 at its front, top and back. A protruding from the wall member 40 web 43 can serve as a gripping portion for adjusting the slider 39; but it can also represent a pointer, which, for example, in combination with a stamped in the upper edge of the stiffening element 26 scale, a qualitative assessment of the slide position allows. On a side opposite the web 43 of the wall element 40, a finger 44 is formed, which extends in the finished assembled state of FIG. 4 through a gap of the rib 30 through the plate 6 below parallel to the wall element 41. A downwardly angled end portion 45 of the finger 44 engages a slot 46 of the lid 15 which is oblique to the latter

Front edge is aligned. Due to the engagement of the end portion 45 in the slot 46, an adjustment of the slider 39 in the longitudinal direction of the profile 35 forces a movement of the lid 15 in the depth direction of the body first

A second difference from the embodiment of Fig. 2 is the replacement of the vertically elongated slots 31 of the eyelets 29, 30 by both in the vertical and in the depth direction of the body 1 extended openings 47 with an obliquely rising front lower edge, each on a hook 33 of the lid 15 rests. The oblique course of the lower edge causes the movement of the cover 15 controlled by the slider 39 in the depth direction to be coupled to a movement in the vertical direction. That is, by a corresponding positioning of the slider 39, a user can cancel the tight contact of the lid 15 with the shell 14 and set a gap between them, the width of which depends on the position of the slider 39. Therefore, cold air exiting the opening 13 no longer flows only through the channel 16, but to a greater or lesser extent through the interior of the shell 14. Thus, if necessary, excess moisture can be removed from the shell 14, and the risk that in case of excessive evaporation by the refrigerated goods in the shell 14 water condensed on the inner sides of the shell 14 or on the lid 15 and the contents of the shell 14 drenched, can be eliminated.

The stiffening element 26 is in this embodiment, apart from the possible scale with respect to the web 43, identical to that of FIG. 2.

Fig. 6 shows the plate 6, the lid 15 and the shell 14 in a perspective view according to a third embodiment. A height adjustment of the lid 15 is not provided in this embodiment; Nevertheless, the openings 47 of the eyelets 29 at the ends of the profile 35 have the shape shown in Fig. 4, because this shape is readily compatible with the described with reference to FIG. 2 operation of the lid 15. So, if different device models with and without

height-adjustable cover 15 are made, for simplicity, identical eyelets 29 are used in all models. The stiffening element 26 is made in one piece here as an injection molded part. This makes it possible to reduce the extension of the groove 28 in the width direction of the body 1. On both sides of the groove 28 projections 48 are formed on the stiffening element 26, projecting against the profile 29. Fig. 7 shows a section through the front upper edge of the shell 14, the lid 15 and the plate 6 in a plane passing through one of the projections 48 level. A rear wall 49 of the hollow projection 48 is slightly inclined, parallel to the front of the profile 35, and forms with the web 27 at an acute angle, in which the protruding rib 36 of the profile 35 engages. The stiffening element 26 and the profile 35 complement each other in height of the projections 48 to a labyrinth seal, which prevents air flow through the interior of the shell 14 even if a deformation, for. B. due to overload, the lid 15 or the shell 14 prevents a tight contact between the two on a part of its circumference.

FIG. 8 shows, in a manner analogous to FIG. 1, a section through an inventive household freezer. The storage space 5 of the device comprises a plurality of extendable shells 14, 50, the bottom plate 20 of an upper shell 50 marking the height up to which a reinforcing element 25 of the next lower shell 14

is pulled up. To allow convenient engagement with the reinforcing element 25, the upper shell 50 is interposed at a lower front edge Bottom plate 20 and front wall 21, a recess 51. The recess 51 may extend over the entire width of the shell 50 or be limited to a central region of the lower front edge.
