Description

Components for refrigeration units

technical field

The invention relates to an assembly for a refrigeration device, in particular for a domestic refrigeration device, comprising a cabinet that can be opened in the manner of a drawer.

Background technique

In refrigeration appliances, especially domestic refrigeration appliances, the interior space is generally divided into compartments by shelf or plate-type evaporators.

In the case of a freezer, all compartments are generally closed at the front by means of drawer flaps, doors or front panels in order to reduce the ingress of heat and moisture when the refrigerated goods are removed.

Compartments located near the bottom typically include drawers that allow vertical access from above. Highly mounted compartments often have baffles or doors, as in the case of drawers at chest or head height it is difficult to see into or remove refrigerated items from the drawers. Whether it is convenient to dispose of a flap or a door in the case of a compartment located at an intermediate height depends on the height of the user. A technical solution that allows good access to the compartment from the front and above is unknown.

Contents of the invention

It is thus the object of the present invention to provide such a solution.

The object of the invention is achieved in that in the case of an assembly for a refrigeration device with a frame and a box on which the box is movable between an inserted position and an unfolded position, the front of the box is at least Partially recessed and the shutter is movable between a seated position where it at least just covers the recess and a raised position relative to the seated position, so that in the raised position there is good visibility and access to the interior of the box good feasibility. Because the baffle covers the recess in the sitting position, the baffle effectively prevents moisture and heat from entering the cabinet when the door of the refrigeration unit is opened but the cabinet is not pulled out.

In the seated position, the baffle advantageously constitutes an upward continuation of the front panel of the box. Thus, the front panel does not take up any more space than the front panel of a conventional pull-out drawer extending over the entire height of the compartment, and the front panel and the front panel can complement each other in an aesthetically pleasing manner, Produce a common, continuous surface in a satisfactory manner.

In order to enable a movement of the flap between the seated position and the raised position, the flap is advantageously mounted rotatably about an axis.

In order for the flap to close automatically by gravity when the box is inserted, the center of gravity of the flap in the raised position is advantageously located in front of a vertical plane extending through the flap axis.

In the raised position, the baffle advantageously at least partially overlaps in the horizontal direction with a portion of the cover. In the deployed position, a large access opening is thus created which enables convenient handling of the contents of the case.

The case advantageously has a recessed grip which facilitates the unfolding of the case. The recessed grip can be provided on the bottom of the box.

In order to automatically transition the flap to the raised position when the casing is unfolded, the movement of the flap is advantageously linked to the movement of the casing. The case advantageously has at least one guide profile comprising an upper region and a lower region, on which upper region the flap rests when the case is in the unfolded position. Since the upper area passes under the apron when the box is unfolded, the apron is lifted and is lowered back into the seated position as soon as the apron loses contact with the upper area when the box is inserted. In the seated position, the trim rests on the lower region of the guide contour or hangs down without contact with the lower region. In particular, the seating position of the flap can be defined by contact with the flanks of the guide contour, wherein the flanks connect the upper region and the lower region of the guide contour.

In order to save construction space, the guide contour is advantageously part of the side wall of the box.

The frame advantageously has a rear wall within which the box is guided between an inserted position and an extended position. The rear wall serves on the one hand to strengthen the frame and on the other hand to completely isolate the enclosure formed by the frame, box and baffle from the remaining space of the refrigerator or freezer. In order to save structural space, the rear wall of the box and the rear wall of the frame are ideally located in the same vertical plane.

To ensure that the case does not fall out when in use, the case and frame desirably have at least one pair of stop surfaces which contact each other in the deployed position. In order to be able to introduce the case into the frame and remove it again if required, one of the contact surfaces is advantageously elastically deflectable in a direction perpendicular to the direction of movement of the case so that both contact surfaces can be moved past each other.

In order to allow the elastic movement of the stop surface, the stop surface is advantageously arranged on a leaf spring.

In order to save construction space and minimize the number of individual parts, the leaf spring is advantageously arranged integrally with the side wall of the box.

In order for the user to be able to remove the case from the frame without the use of tools, the user must be able to deflect the elastically movable stop surface. This is advantageously possible if the leaf spring is at least partially exposed when the case is in the unfolded position.

The frame of the assembly is advantageously installed in the housing of the refrigeration device, or the frame is advantageously already formed by the inner container of such a refrigeration device housing.

When the frame is installed in the housing of the refrigeration device, the frame and the box advantageously have a pair of contact surfaces which, in the inserted position, come into precise contact with each other. It can thus be ensured that, irrespective of possible manufacturing tolerances of the housing, in the inserted position, the front panel of the housing and the baffle are vertically aligned.

Detailed ways

Figure 1 shows an internal view of a door 2 of a domestic refrigeration device, in particular a freezer or refrigerator. The structure of the door 2 is known, with an outer shell formed from sheet metal, an inner wall 1 deep-drawn in plastic and a cavity closed by the outer shell and inner wall 1 and filled with insulating synthetic resin foam. A peripheral door frame 3 with two uprights 4 extends along the edge of the inner wall 1 . Support protrusions 6 are provided on inner side wings of the upright portion 4 facing each other. The support projection 6 is provided for mounting built-in components. Such a built-in element is the door frame 7 for the bottles. The door frame 7 is in the form of a box with an open top. A recess 8 can be seen on one side wall of the door frame 7 , which is formed as a groove open at the bottom on the outer surface of the side wall facing away from the viewer. Corresponding grooves are also provided on the opposite side walls of the door frame 7 . The door frame 7 is fixed to the inner wall 1 in a known manner, since the bottom-opening groove is mounted on two support projections 6 .

The components of the invention are arranged below the portal frame 7 . This assembly is substantially in the form of a parallelepiped and comprises a frame 9 , a baffle 10 and a box 11 which is displaceably guided in the manner of a drawer on the frame 9 . At least the structure of the assembly can be seen more easily in FIG. 2 , which shows a sectional view of the assembly in the direction of depth.

The frame 9 comprises two lateral cheeks 12, wherein said lateral cheeks form the two narrow sides of a parallelepiped; and a cover profile 13 extending between said lateral cheeks. The cover profile 13 is L-shaped in cross-section, with horizontal wings 14 forming a large part of the top of the parallelepiped and vertical wings 15 forming the rear of the parallelepiped a part of. Since the two wings 14 , 15 are fixed to the lateral cheeks 12 , the cover profile produces a rigid, structurally stable connection between the lateral cheeks 12 . Each lateral cheek 12 has on its outer side a bottom-opened groove 29 (see FIG. 3 ) which, like the groove of the door frame 7 , is used to connect the lateral cheek to the bearing projection of the door 2 Part 6.

The box body 11 includes a bottom panel 16 , right and left sidewalls 17 , a front panel 18 and a rear wall 19 . As shown in FIG. 2 , the top edges of the two side walls 17 are stepped, with a high rear section 20 , a low front section 21 and vertical wings 22 connecting the sections 20 , 21 . The rear wall 19 and the top edge of the front panel 18 are located at the level of the low front section. In the inserted position of the box 11 as shown in FIGS. 1 and 2 , the rear edge of the side wall 17 hits the wing 15 of the cover profile 13 . The rear wall 19 and the wings 15 extend in a common vertical plane and together form a substantially closed rear part of the parallelepiped.

The baffle 10 has an L-shaped cross section. In the position shown in Figures 1 and 2, the front panel 23 of the baffle 10 forms an upward continuation of the front panel 18 of the box 11, so that the two together form the front part of a substantially closed parallelepiped. In the position shown in FIG. 1 , the horizontal wings 24 of the baffle 10 form the top of a parallelepiped.

The baffle 10 is pivotably suspended on the lateral cheeks 12 via two L-shaped lugs 25 , on the free ends of which lugs carry a king pin (not visible in the figure). The center of gravity of the baffle 10 is located in front of the pivot axis 26 shown in dot-dash line in FIG. 2 . The knee element 27 of the lug 25 sits on the vertical side wing 22 and holds the front panel 23 flush with the front panel 18 of the box 11 when the side wall 17 hits the wing 15 precise vertical position.

A recessed grip portion 28 is formed in the bottom panel 16 near its front edge, and the user can grasp the recessed grip portion to pull the box body 11 forward from the frame 9 . At this point, the wing 22 is pressed against the knee element 27 of the lug 25 and the flap 10 is pivoted upwards. As soon as the knee element 27 reaches the upper section 20 of the side wall 17, the flap 10 is in a raised position, in which, as shown in FIGS. The front edge of the profile 13 is behind and engages in a recess between the lug 25 and the front panel 23 . Furthermore, in this position, the center of gravity of the flap 10 is located in front of the axis 26, so that when the box is pushed back to the position shown in FIGS. 1 and 2, the flap 10 is automatically lowered closed again.

Figures 3 and 4 show the assembly with the flap 10 in the raised position and the box 11 in the fully extended position, in a perspective or cross-sectional view similar to Figure 2 . The raised bezel 10 and the low front panel 18 ensure unobstructed access to the cabinet 11 .

A leaf spring 30 integrally formed with the side walls 17 is located in the rear upper corner of each side wall 17 of the case 11 . FIG. 5 shows an enlarged cross-sectional view of the side portion 17 and its surroundings in the longitudinal direction of the leaf spring 30 in the maximum extended position. The latch portion 31 is formed on the outer side of the leaf spring 30 . The upper surface 32 of the latch pointing perpendicular to the direction of movement of the case 11 is in contact with the vertical rib 33 of the lateral cheek 12 and thus limits the freedom of movement of the case so that the horizontal rib 34 of the lateral cheek 12 The engagement with the groove 35 on the side wall 17 of the case 11 will not fail.

In the deployed position, the front part of the leaf spring 30 (on the right in FIG. 5 ) is exposed so that the user can press the front part of the leaf spring with his finger and release the overlap of the stop surface 32 and the rib 33 . The box 11 can then be removed from the frame 9 .

In order to be able to mount the box 11 again in the frame 9 , it is sufficient to once again achieve the engagement between the grooves 35 on both sides of the box and the ribs 34 and then press said box against the frame 9 . The beveled surface 36 on the free end of the leaf spring 30 now comes into contact with the rib 33 , the leaf spring 30 is pushed aside and the box 11 is latched onto the frame 9 again.

Figure 6 shows another embodiment of the assembly of the invention, representing a schematic cross-sectional view of a freezer. The interior of the freezer is divided into compartments. The compartment 37 at the height of the user's head is closed by means of a flap 38 . The user can swing the shutter 38 to one side so that the interior of the compartment can be viewed and accessed horizontally. A drawer 39 is arranged in a compartment near the bottom, said drawer being able to be pulled out by the user so as to be able to see and access it from above. The variant of the assembly of the invention with the box 11 and the baffle 10 is arranged at an intermediate height. The inner container serves as a frame 12 on which the box 11 is guided and on which the flap 10 is pivotably suspended.
