Description

Technical field

The present invention relates to a refrigerating appliance, in particular to a domestic refrigerating appliance, with a housing and a door that surround a thermally insulated storage chamber, as well as with a container that can be pulled out of the storage chamber.

State of the art

Such containers are most often located individually or in a group of several containers located one above the other in the lower part of the storage chamber, as a result of which the user (in particular, the refrigerator, standing on the floor) is forced to tilt so that he can grab the handle of the container and extend it container. Most often, containers are made of plastic by injection molding as a whole. For reasons of container stability, it is advisable to position the handle near the edge of the container on which the front wall and the bottom plate of the container meet. The deep location of the handle on the container, mounted deep down in the storage chamber, forces the user to tilt strongly when the container is pulled out, which makes it difficult to use the container.

Disclosure of invention

The objective of the invention is to develop a refrigeration apparatus with a retractable container, which will facilitate user access to the container.

A refrigerating apparatus is understood, in particular, as a household refrigerating apparatus, that is, a refrigerating apparatus used in the household, for example a refrigerator or a combined refrigerating-freezing apparatus. The refrigerator can be equipped with the No Frost system, which provides for cooling the storage chamber with cold air entering the storage chamber from the evaporator chamber.

The problem is solved due to the fact that in the refrigerator, in particular the household refrigerator, which contains a housing and a door surrounding a heat-insulated storage chamber, as well as a container that can be pulled out of the storage chamber, and a plate covering the container in the retracted the chamber for storing the position, the gripping bar on the front wall of the container extends at least to the front edge of the plate. In particular, the gripping plate protrudes up to the leading edge of the plate. This design allows you to grab the handle from above, from almost the same direction from which the user will subsequently gain access to the contents of the container open from the upper side. Due to the high position of the gripping bar, the angle that the user has to bend when using the container is reduced. Preferably, the container, when retracted into the storage chamber, is only partially covered by a plate, and at least a gripping bar of the container protrudes above the front edge of the plate.

The gripping plate is especially suitable when the container is guided in the housing along telescopic rails with low friction losses, and only small efforts are required to extend it.

Preferably, the gripping bar is made in the form of an element separate from the front wall of the container, which is fixed to the upper edge of this front wall. As a result, it is possible to easily make a gripping bar, which will have a significantly higher bending strength compared to the front wall. Due to the fact that the gripping plate makes a significant contribution to ensuring the rigidity of the container necessary for normal operation, the walls of the container can have a relatively small thickness, which reduces costs.

Preferably, for the sake of simplicity, the gripping bar is mounted on the upper edge of the front wall.

Preferably, the gripping bar is made of metal. This is due, on the one hand, to high load capacity and, on the other hand, to design considerations.

The mounted gripping bar allows the front wall to be transparent on most of its surface and preferably flat. Thanks to this, you can clearly see the contents of the container without pulling out the container.

The leading edge of the plate covering the container in the retracted position can also be reinforced by the profile mounted on it. Preferably, in order to unify the appearance, at least the surface of this profile consists of the same material as the gripping plate. Since both of these elements in the retracted position of the container are located directly next to each other, the observer can perceive them as a whole.

Preferably, the profile mounted on the plate comprises a downward directed rib. On the one hand, this rib significantly increases the stiffness of the profile, and on the other hand, it can interact with the gripping bar (as will be described below), closing the container in the retracted position.

To ensure ease of handling of the container, a gripping recess is preferably left between the gripping bar and the leading edge of the plate. The user can insert fingers into this recess from above to grab the back of the gripper bar and extend the container.

The recess may extend over the entire width of the container. This allows, in particular, to produce a gripping bar and profile with optimal costs by hot pressing or extrusion.

Alternatively, the recess may be covered on both sides by the protrusions of the gripping bar. Due to the fact that these protrusions, together with the leading edge of the plate, form a labyrinth seal and help isolate the interior of the container from the surrounding storage chamber and, in particular, to limit the air exchange between the container and the surrounding storage chamber.

Preferably, the gripping bar comprises a flange which, when the container is retracted, enters under the plate. Such a flange at low material costs can significantly increase the rigidity of the gripping bar. In addition, the rim eliminates the possibility of objects falling into the container through the gap between the gripping plate and the front edge of the plate.

In a further preferred embodiment, the container may be closed tightly by a cover plate. Thus, it is possible to retain moisture evaporating from the refrigerated products stored in the container in the container. As a result, further evaporation from refrigerated products is limited and their storage ability is improved.

In order for the lid to remain in the storage chamber when the container is pulled out, it is expediently suspended on the plate.

The lid support can also be the edge of the gripping bar, in particular, the aforementioned edge, which, when the container is retracted, enters under the plate.

Suitable cover can be rearranged in height. That is, when tight closure of the container is undesirable, the lid may be held at some distance from the container.

Advantageously, the slider for rearranging the lid in height may be positioned for rearranging along the leading edge of the plate.

The implementation of the invention

The figure 1 presents a schematic sectional view of a household refrigeration unit with a No Frost system, which contains a housing 1 and a door 2 surrounding an internal cavity. The internal cavity is divided by a shell 3, mounted under the cover of the housing 1, into the chamber 4 of the evaporator and chamber 5 for storing refrigerated products. The storage chamber 5 is divided by a horizontal plate 6, which can be made, in particular, in the form of a glass plate. As a result, a compartment 7 for a drawer 14 is formed near the bottom.

The evaporator 8 and the fan 9 are arranged in a known manner in the evaporator chamber 4. When the fan 9 is operating, it draws air from the storage chamber 5 through openings 10 on the leading edge of the shell 3 into the evaporator chamber 4. In this chamber, the air is cooled in contact with the evaporator 8, after which it is pushed by the fan 9 into the distribution channel 11, which descends down the rear wall of the housing 1. Several outlet openings 12 of the distribution channel 11 exit into the storage chamber 5 at various levels. The lowest outlet 13 extends into the compartment 7 under the plate 6. The contents of the container 14 are cooled essentially by the flow of air from the outlet 13, which passes through the channel 16 located between the plate 6 and the lid 15 covering the container 14.

A similar design can be implemented in a refrigerator with a cold wall due to the fact that the flow of air cooled on the evaporator integrated into the rear wall of the housing is directed through the channel between the cover of the drawer and the plate located above it.

A container 14 mounted on telescopic rails 19 is shown in figure 1 in two positions. The extreme retracted (into compartment 7) position is indicated by a dotted line, and the extreme extended position, in which the entire container 14 is located in front of the leading edge of the plate 6, is indicated by solid lines.

The container 14, having a substantially rectangular parallelepiped shape, contains a main element made by injection molding as a unit or as an integral element. The main element contains a horizontal bottom plate 20, a front wall 21, a rear wall 22, the height of which is slightly less than the height of the front wall 21, as well as side walls 23 that connect the walls 21, 22. The side walls 23 have upper edges evenly descending to the rear wall 22 24, as well as ledges 25, each of which includes one of the telescopic rails 19. At least the front wall 21 is transparent and even, so that the contents of the container 14 can be seen without pulling out the container 14.

A gripping bar 26 (hereinafter referred to as stiffening element 26) is put on the upper edge of the front wall 21. The stiffening element 26 can be made in the form of a pressed profile of a U-shaped section, the groove open to the bottom being put on the front wall 21 with a frictional closure, fixed on it or glued to it. In addition, the profile contains a flange 27 extending above the bottom plate 20 flush with the upper edges 24, and plugs covering the groove at both ends of the profile. It is also possible that the entire stiffening element 26, including the plugs, is made as a whole by injection molding.

In the extreme retracted position of the container 14, the stiffening element 26 together with the leading edge of the plate 6 defines a gripping recess 28, which is open upwards, into which the user can insert fingers from above to extend the container 14. The lip 27, which protrudes in the opposite direction to the extension, significantly increases the bending resistance element 26 stiffness. As a result, the pulling force is distributed over the entire width of the front wall 21 and is transmitted to the main element of the container 14.

The cover 15 is suspended on the plate 6 by means of hooks 33, 34 and eyelets 29, 30, which are adjacent to the four corners of the plate 6 and the cover 15. Each of the eyes 29, 30 has a vertical slot 31 into which the hooks enter with a vertical gap 33, 34. Therefore, the cover 15 can move vertically, but cannot move horizontally. In figure 1, the cover 15 is shown in the resting position, in which it is not supported by the container 14 and is held only by the plate 6. The hooks 33, 34 are located on the lower edges of the slots 31. As shown in the figure, this resting position is below the level of the upper edges 24 of the side walls 23 the container 14 in the extreme retracted position, and the inclination of the lid 15 in the resting position is greater than the inclination of the edges 24. Since the front edge 17 of the lid 15 is located above the upper edge of the rear wall 22, the container 14, when inserted into the compartment 7, easily passes under the lid 15 and begins to touch with the cover 15 and lift it only shortly before reaching the extreme retracted position. Since the inclination of the lid 15 is greater than the inclination of the edges 24, only the upper edge of the rear wall 22 first contacts the lid 15. As the container 14 moves inward, the lid 15 first rotates. Only after the back of the lid is raised so that the inclination of the lid corresponds to the inclination of the upper edges 24 of the side walls 23, the edges 24 and the lid 15 will come into contact over the entire area. When the drawer reaches its extreme retracted position, the upper edges of the walls 22, 23 of the container 14 and the back of the flange 27 will touch the lid 15, as a result of which the interior of the container will be closed essentially tight and in any case tight.

Thus, in the container 14 due to evaporation from the refrigerated products stored therein, higher air humidity can be maintained compared to the surrounding storage chamber 5, the air of which constantly loses moisture as a result of contact with the evaporator 8. As a result, the drying of the refrigerated products decreases and improves their ability to store.

Figure 3 illustrates this state of affairs with an enlarged section of the leading upper edge of the container 14, the lid 15 and the plate 6. The figure shows that the front edge of the plate 6 is reinforced by a worn profile 35, which, like the stiffening element 26, is made of aluminum and / or has a surface finish identical to that of the stiffener 26. The front lugs 29 are worn at the ends of the profile 35. The rear lugs 30, not shown in FIG. 3, are part of the profile 18, worn on the trailing edge of the plate 6. From the main part of the profile 35, covering the front edge of the plate 6, a rib 36 protrudes at an angle downward. which ends almost at the edge 27. The smooth edge region 37 of the cover 15 is adjacent to the edge 27 behind the rib 36, as a result of which the rib 36 does not interfere with the possible vertical movement of the cover 15.

The edge region 37 extends along all four sides of the cover 15 around the central region 38. While the edge region 37 is flat, which allows it to fit snugly against the lip 27 and the upper edges 24 of the side walls 23 and the rear wall 22, the central region 38 is curved with the purpose of increasing the stiffness of the cover 15 during bending.

Figure 4 shows a perspective view of the second embodiment of the plate 6, lid 15 and container 14, similar to Figure 2. The most noticeable difference from figure 2 is the slider 39, which is fixed on the profile 35, which makes the plate 6 stiff. Figure 5 shows a perspective view of this the slider 39 at an angle from below, together with the portion of the flat front edge region 37 of the cover 15, but without the plate 6 and profile 35. The slider 39 contains three integral, similar to an asymmetric U-shaped profile connected at right angles to the element 40, 41, 42 walls, which in the assembled state (see Fig. 4) cover the front, upper and rear sides of the profile 35. The transverse rib 43, protruding forward from the wall element 40, can serve as a handle for moving the slider 39, as well as an indicator, which, for example , together with a scale extruded on the upper edge of the stiffening element 26, allows to qualitatively determine the position of the slider. A protrusion 44 is formed on the side of the wall element 40 opposite to the transverse rib 43, which in the assembled state (see FIG. 4) passes through a recess in the rib 36 into the region below the plate 6 parallel to the wall element 41. The end portion 45 of the protrusion 44, bent down, enters the slot 46 of the cover 15, which is oriented at an angle relative to the front edge of the cover. Due to the engagement of the final section 45 over the slot 46, moving the slider 39 in the longitudinal direction of the profile 35 causes the cover 15 to move along the depth axis of the housing 1.

The second difference from the variant shown in figure 2 is the replacement of vertically elongated slots 31 of the eyes 29, 30 with elongated both vertically and along the axis of the depth of the housing 1 with holes 47 with a lower edge rising at an angle forward, on which lies the corresponding hook 33 lids 15. The inclination of the lower edge leads to the fact that the movement of the lid 15 along the depth axis, controlled by the slider, is accompanied by the vertical movement of the lid. That is, by moving the slider 39 to the appropriate position, the user can remove the lid 15 from tight contact with the container 14 and create a gap between the lid and the container, the width of which will depend on the position of the slider 39. Therefore, the cold air leaving the opening 13 is not only distributed along channel 16, but also to a greater or lesser extent along the inner space of container 14. Due to this, if necessary, it is possible to remove excess moisture from container 14 and also prevent the formation of condensate on the inside these sides of the container 14 or cover 15, due to excessive evaporation of chilled goods in the container 14, and impregnating the contents of the container 14, the condensate.

In this embodiment, the stiffening element 26 is identical to the element shown in FIG. 2, with the exception of a possible scale opposite the transverse rib 43.

The figure 6 presents a perspective view of a third embodiment of the plate 6, the cover 15 and the container 14. In this embodiment, the rearrangement of the cover 15 in height is not provided. However, the holes 47 of the eyes 29 at the ends of the profile 35 have the shape shown in figure 4, since this shape is compatible with the principle of operation of the cover 15, described in connection with figure 2, without taking any additional measures. Thus, the same eyes 29 for the sake of simplicity can be used in any models, regardless of the possibility of moving the cover 15 in height.

The stiffening element 26 in this case is made as a whole by injection molding. This allows you to reduce the stretching of the recess 28 along the axis of the width of the housing 1. On both sides of the recess 28, protrusions 48 are formed on the stiffening element 26, which protrude towards the profile 29. Figure 7 shows a section of the front upper edge of the container 14, lid 15 and plate 6 in a plane passing through one of the protrusions 48. The rear wall 49 of the hollow protrusion 48 is located at a slight angle parallel to the front wall of the profile 35, and forms an acute angle with the lip 27, into which the protruding rib 36 of the profile 35 enters. Thus, the stiffening element 26 and the profile 35 complement each other at the level of the protrusions 48, forming a labyrinth seal, which prevents the passage of air through the interior of the container 14 even when the deformation of the lid 15 or the container 14, caused, for example, by overload, prevents the tight contact of these two elements in which or parts of their volume.

Figure 8 shows a section of a domestic freezer according to the invention, similar to figure 1. The storage chamber 5 for storing the freezer contains several drawers 14, 50, the bottom plate 20 of the upper container 50 forming an upper limit to which the stiffening element 26 can be raised located below container 14. To provide convenient access to the stiffening element 26, a recess 51 is provided on the lower front edge of the upper container 50, between the bottom plate 20 and the front wall 21. The recess 51 can walk across the width of the container 50 or be limited to a central region lower front edge.
