Description

Technical field

The present invention relates to a refrigerating apparatus, in particular to a domestic refrigerating apparatus, which comprises a storage chamber and located in the storage chamber, at least the closest container, as well as a container for such a refrigerating apparatus.

State of the art

The air in the storage chamber of the refrigeration unit is constantly dehydrated during operation, in contact with the cold surface of the evaporator. Due to this process, low air humidity in the storage chamber contributes to the drying of unpacked, breathable refrigerated products, such as fresh vegetables, fruits, etc. In a closed container, it is possible to maintain a higher air humidity compared to the rest of the storage chamber, whereby the refrigerated products in such a container dry out more slowly than the products openly lying in the storage chamber. Therefore, such a container is usually called a container or a drawer for vegetables.

The contents of such a container are cooled essentially due to the fact that heat is removed from the container to the surrounding chamber for storage through the walls of the container. In order to ensure the most uniform temperature distribution in the built-in container, it is advisable to provide cooling, preferably on its upper side, since the air cooled at the container lid is directed downward and distributed over the container. As a result of this, however, moisture given off by the cooled air settles mainly on the lid and drips from the lid onto the cooled products. The resulting moistened areas of chilled products impair their storage capacity, creating good conditions for the development of putrefactive bacteria and mold growth.

Disclosure of invention

The objective of the invention is to develop an embedded container for a refrigeration apparatus, in which humidification of refrigerated products with condensate will be minimized.

By a refrigerating apparatus is meant, in particular, a household refrigerating apparatus, that is, a refrigerating apparatus used in a 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 in that the built-in container for the refrigeration apparatus, in particular the household refrigeration apparatus, which comprises a lid open from the upper side and a lid covering the upper side of the lid, the lower surface of the lid is inclined for at least most of its area. The slope leads to the fact that water droplets deposited on the surface of the lid move downhill to the most deeply lowered region of the surface, after which they break off or flow from it. Due to the fact that the refrigerated products are away from these humid places, they can be protected from moisture by condensate. As a result, the storage ability of the refrigerated products can be improved.

To keep the space occupied by the lid within reasonable limits, the slope should not be too large. The more important is the inherent rigidity of the cover, which will not allow the slope to disappear or even change direction due to the deformation of the cover, which could result in condensation getting into places not provided for this. To impart rigidity to the lid, it is advisable that the inclined surface is curved in at least one direction, preferably even in two directions, that is, curved like a cylinder, and preferably even a sphere.

For accurate localization of places where it is possible to swell water, the lower edge of the inclined surface is preferably made in the form of an edge for draining.

If such an edge for draining is made in the form of a rib protruding from the lid, then it will also perform the function of reinforcing the lid.

Preferably, the edge for swelling separates the inclined surface from the supporting surface of the lid adjacent to the tray. Due to this, firstly, condensate leakage out through the area between the tray and the lid is prevented, and secondly, condensation swelling down along the walls of the tray is prevented. Instead, droplets of condensate remain hanging on the drip edge until they reach the critical value necessary for tearing. After that, the drops fall down. Since, as a result, the condensate remains in the container, it can re-evaporate, thereby maintaining the humidity of the air in the container. This, in turn, reduces the drying of refrigerated products in the container.

If the tray contains a bottom plate and walls surrounding the bottom plate, then the drip edge with the lid closed will preferably be located above the bottom plate. This ensures that the flowing water cannot remain hanging on the walls, but will fall directly on the bottom.

Advantageously, the bottom plate comprises at least one raised region and one groove located between the raised region and at least one of the walls. Such a groove improves the stability of the shape of the tray. If, in addition, the drip edge with the lid closed is located above the groove, then the draining condensate will be guaranteed to directly flow into the groove and thereby be kept away from the cooled products lying on the raised area of the bottom plate.

Preferably, such a groove is laid around the perimeter around at least one raised region.

The drip edge should be located above the line that connects the opposite edges of the lid adjacent to the tray. This will allow, in particular, to extend the tray of the built-in container from the refrigerator to gain access to its contents without having to lift the lid.

The invention also relates to a refrigerator with an integrated container of the type described above.

In order to ensure metered air exchange between the interior of the container and the storage chamber surrounding it, the lid of the built-in container in the refrigerator can move along an ascending path between the two extreme ones, i.e. persistent positions, especially closed and wide open extreme positions.

It is advisable that the edge for draining is located on the lid so that it is located above the tray in any of the extreme positions.

In addition, to facilitate the extension of the tray without the lid, it is advisable to make the back wall of the tray below the front wall of the tray.

Brief Description of the Drawings

Other features and advantages of the invention follow from the following description of embodiments, taking into account the attached figures, which depict:

Figure 1: a schematic sectional view of an embedded container of the invention, with a tray and a lid suspended on a shelf of a refrigerator.

Figure 2: perspective view of the cover.

Figure 3: perspective view of the cover according to another embodiment.

Figure 4: a schematic sectional view of a refrigerator equipped with an integrated container shown in figures 1 and 2.

The implementation of the invention

The built-in container, a schematic cross-section of which is shown in figure 1, contains a tray 1 and a cover 2. Each of these parts is made by injection molding of plastic as a whole. Preferably, the plastic has a transparency of glass, so that the user can see the contents of the container without opening it.

The tray 1 has a substantially rectangular parallelepiped shape with an open upper side, and, of course, this upper side has a slight inclination from the front wall 3 of the tray to the rear wall 4 of the tray. Horizontal bridges 5 are formed on the upper edges of the front wall 3 and the rear wall 4, which serve, on the one hand, to provide rigidity and, on the other hand, to provide support for the cover 2. A corresponding jumper may also be provided on the upper edges of the side walls 9 tray 1.

The bottom plate 6 of the tray 1 comprises a raised central region 7 and a groove 8 that extends around the central region 7 and separates it from the front wall 3 and the rear wall 4, as well as the side walls 9 of the tray 1. The central region 7 has an uneven surface, in this case in the form of parallel ribs 10 and grooves 11. This prevents the entire area of the cooled products, not shown in the figure and laid in the tray 1, from touching the bottom 6 and to allow blowing of the cooled products, including from the bottom.

The grooves 11 are also located slightly above the surrounding groove 8. They can be tilted to the side walls 9 so that water, which can drain from the cooled products, does not accumulate in the grooves 11, but flows into the groove 8.

Cover 2 in figure 1 is shown in two positions. The dashed line shows the closed position in which the lid is adjacent to the jumpers 5 on the upper edges of the tray 1, and the solid lines indicate the open position in which the lid is lifted from the tray 1. The central region 13 of the lid 2 is curved in the form of a gentle dome as in the plane of the cross section of figure 1, and in a plane perpendicular to it. The flat edge strip 12, which surrounds the central region 13 around the perimeter and in contact with the jumpers 5 of the tray 1, occupies only a small part of the area of the lid 1. The flat ribs 14, 15 extend a short distance from the edge strip 12 and are essentially parallel to it along the lower side of the central region 13. These ribs form, as shown, in particular in a perspective view of the lid (Figure 2), a closed quadrangular frame. Condensate settling in the middle 16 of the central region surrounded by this frame moves, following the slope of the lower side of the lid, to the edge. In this case, the condensate enters the ribs 14 or 15. The ribs 15 parallel to the side walls 9 are inclined to the rear wall 4, as are the upper edges of the side walls 9. Therefore, condensate droplets falling on one of the ribs 15 are prone to moving backward until they come into contact with rib 14 located near the rear wall. Drops fall from this rib when they reach a critical value.

The width of the groove 8 is selected so that the rear rib 14 is located above the groove 8, at least with the lid 2 closed. As a result, water dripping down from this rib 14 falls directly into the groove 8. The width of the groove 8 in the area near the back the wall 4 can be so large that the rear rib 14 is located above the groove 8 even with the lid 2 open. However, this is not a requirement (see Fig. 1), since with the lid open, moist air can exit the container instead to condense on the roofs DEFINITION 2. Therefore, reducing the risk of formation of water droplets on the rib 14 and fall into the central area 7 of the bottom 6.

As shown in FIG. 2, in the two front corners of the upper side of the cover 2 there are two projections 17 with laterally extending pins 18. In the two rear corners of the upper side of the cover 2 there are two hooks 19, each of which goes into the tongue 20 with the lower side, which has a straight slope in the backward direction. The trunnions 18 in the position in which they are installed in the refrigeration unit enter the slots made at an angle in the slats 21. These slats are located on the lower side of the plate 22 (see figure 1) mounted above the container. Holes 24 are provided in the slats 23 located on the trailing edge of the plate 22, each of which includes a corresponding tongue 20. The trunnions 18 and tongues 20 allow the lid 2 to move between a closed and wide open position along a path that rises forward at an angle.

Figure 3 presents a view of a different embodiment of the lid 2, which is similar to figure 2. On the trailing edge of the lid 2, a flat cutout 25 is formed, which can, for example, be installed on a cold air duct that extends vertically along the rear wall of the refrigerator where the container is installed. According to this embodiment, a corresponding cutout may also be provided in the rear wall of the tray. This shape of the back wall makes it difficult to place large objects to be cooled in the corners of the tray on both sides of the cutout 25, due to which condensate, which due to the inclination of the lid is mainly collected on this rear edge 14, is likely to be able to freely drip onto the bottom of the tray without touching the cooled products.

Figure 4 presents a schematic section of a refrigeration apparatus, which is equipped with an integrated container of the type described above. The housing 30 and the door 31 limit the storage chamber 32, in the lower part of which the plate 22 separates the compartment for the built-in container. The evaporator chamber 33 is located under the cover of the housing 30 and contains an evaporator 34 and a fan 35. The fan draws air from the storage chamber 32 through openings 36 formed in the casing 37 enclosing the evaporator chamber 33 and, after cooling on the evaporator 34, pushes air into the distribution channel 38, which descends down the rear wall of the housing 30. The distribution channel 38 has outlet openings 39, 40 that extend into the storage chamber 32 for storage at various heights. The lowest outlet 40 extends into the compartment of the built-in container under the plate 22. When the lid 2 is in the closed position (again shown by a dotted line), cold air leaving the outlet 40 passes mainly through the channel 41 between the plate 22 and the lid 2 cooling the contents of the container through the lid 2. With the lid 2 open, cold air at least partially passes between the tray 1 and the lid 2, as a result of which excess moisture is removed from the container and, if necessary, the lower one is dried blackthorn cover 2.

The invention can be applied not only in a refrigerator with the No Frost system shown in Figure 4. At no additional cost, a refrigerator with a cold wall can be made so that the flow of cold air caused by cooling on the evaporator at least partially passes over the lid of the built-in container or, if the lid can be rearranged in height, between the tray and the lid of the built-in container.
