Abstract

The shelf (1) for a refrigeration device comprises a closed main section (2) and a grid-like edge section (3).

Description

The shelf of refrigerating plant

Technical field

The present invention relates to be used for be assembled to the shelf of the inner room of refrigerating plant.In the refrigerating plant in modern times, this shelf often is applied to the glass plate that is enclosed in the frame of plastic.Infringement is avoided at the edge of frame of plastic cover glass plate, and is provided with protection web, bolt etc., and they are used for the shelf that suspends on the sidewall of the inner room of refrigerator.

Background technology

Can utilize the space efficiently in order to make, this shelf should extend on the big as far as possible bottom section of inner room.Here the problem that is produced is, utilization has the refrigerating plant of cold wall construction, be placed in the freezing article that contact with evaporator wall on this shelf with freeze wall, even this is that the temperature that is lower than 0 ℃ can easily reach in this area contents because required temperature is positive in refrigerating plant.In order to prevent that freezing article from contacting with evaporator wall, the shelf that is used for this device is provided with upright backstop web usually in its Background Region, and described backstop web prevents that freezing article are too near to evaporator wall.

Utilize frostless refrigerating plant, indoorly do not reach any surface that is lower than 0 ℃ of temperature usually, thereby do not have article freezing danger on wall interior.However, freezing article still must be held and leave rear wall, and to keep a gap between the trailing edge of rear wall and shelf, by described gap, cold air can circulate, thereby guarantee in the height of inner room the even cooling to inner room.This has also caused the part of inner space well not used.This problem also caused the rear wall of inner room and will whole height from formed air-flow between the edge of this rear wall shelf at interval at inner room in along streamlined flow, thereby half place's air circulation is lower below in each cabin.

Summary of the invention

The objective of the invention is to form a kind of shelf that allows the refrigerating plant of efficient usage space.

At the shelf of the body section that is provided with encirclement, the edge section by shelf is set to grid and realizes above-mentioned purpose.If necessary, can use grid to hold freezing article.Meanwhile, these parts of the grid that the article that are not frozen occupy can be used for the not exchange of the air between the homonymy of shelf.In fact eliminated the obstruction completely by the freezing grid of erectting on the top of grid that article caused, this is because the user loads shelf seldom so to high-density, thereby covers their edge section in the mode without any the gap.

In addition, the free cross section of the grid of the exchange of air of the volume that is enough to be used in expecting can easily be set up by the edge section with enough degree of depth, and the wherein said degree of depth is at least 3 centimetres, especially greater than 3 centimetres.

If the body section of shelf is implemented in known manner by the glass plate that is enclosed in the framework, then grid advantageously can be set to parts with framework.

Especially advantageously the rib that has inclination for grid.These ribs can be along the lateral refraction air-flow of grid of flowing through, and thereby guarantees that enough cooling blasts are by the cabin by shelf limited.Structure by the difference on the zones of different of grid tilts depends on air circulation, and the cooling air is divided to the shelf below or is diverted on its area supported along different directions, thereby different zones is supplied with the cooling air.In this case, can force to realize cooling air circulation statically or by the use fan.

The angled cross section of rib preferably has the wing of inclination of refraction air-flow, and the wing of level at height place that is positioned at the upside of shelf, and wherein if necessary, freezing article can be placed on the wing of described level.

For flow resistance is kept lower, rib preferably is in the position at obtuse angle.

Preferably, rib is downward-sloping towards body section, thereby the even velocity component is applied to the cooling blast in the cabin that is arranged in the shelf below.

In order to improve stability, rib preferably is connected with each other by web.

Description of drawings

By the explanation of the following illustrative examples that provides of reference accompanying drawing, will know other characteristics of the present invention and advantage.Accompanying drawing shows:

Fig. 1 is the perspective view of shelf of the present invention;

Fig. 2 is the cutaway view of posterior region of the shelf of Fig. 1; And

Fig. 3 is the schematic cross sectional views that is equipped with the refrigerating plant of shelf of the present invention.

The specific embodiment

In Fig. 1, be divided into body section 2 with the shelf shown in the mode of perspective view, when shelf 1 is contained in the refrigerating plant, described body section be positioned at the door the front side just be positioned at the door near; And the edge section 3 of close rear wall.Body section 2 is to be formed by plate 4, and wherein said plate 4 is to be made by safety glass, and described safety glass is surrounded by single-piece molding framework 5, and described framework is made of plastics.Also unshowned in the drawings metal profile can embed in the framework 5, with reinforced frame.

Edge section 3 is arranged to parts with framework 5, and comprises a plurality of ribs 6, and the end of described rib is connected to the lateral profile of framework 5 by the profile 7 that forms concordant extension.The flexible a little tongue 8 of corresponding formation on the rear end of profile 7, described tongue is used for shelf 1 is locked in groove, and wherein said groove is formed on the sidewall of inner room of described refrigerating plant.

Between profile 7 and be parallel to these profiles, rib 6 also is connected by a plurality of webs 9.As shown in Figure 2, web 9 has upper edge 10, described upper edge 10 respectively between two ribs 6 in the past backward, just in Fig. 2 from right to left, downward-sloping, thereby in the perspective view of Fig. 1, do not find out web 9, and described web does not prevent that the uper side surface of edge section 3 is by wiping.

Rib 6 comprises the angled cross section with horizontal tail 11 respectively, and the described wing 11 is concordant with the upside of framework 5, thereby rib 6 forms smooth surface in combination, and freezing article can be placed on the described smooth surface.The angled wing 12 of rib 6 is towards the front side, just, downward-sloping towards the right side of Fig. 2, thus make the cooling blast that points to shunt forward downwards, the cooling blast of wherein said downward sensing impacts rib 6 from the top, and thereby produces the air-flow that points to forward below shelf 1.Simultaneously, the angled shape of rib 6 is utilized less material to make to have higher load capacity.

Fig. 3 shows operation of the present invention with reference to the schematic cross sectional views with frostless refrigerating plant of evaporimeter 13, and wherein said evaporimeter is contained in the independent chamber 14 in the upper-side area of refrigeration device housing.Also unshowned in the accompanying drawings ventilator is by near the inlet 16 of the door in the chamber 4 cooling chamber 15 suction airs from device, and wherein air flows along evaporimeter 13, and discharges cooling once more at outlet 17 places near the rear wall of housing.Cooling blast flows along the rear wall of housing, and when so doing, impacts the edge section 3 of a plurality of shelves 1, and the rib of described edge section is shunted cooling blast forward.Thereby the part of air-flow flows forward below a shelf 1 in each cabin 18, and all cabins 18 are cooled off equably.Cooling blast is in the forward edge of shelf 1 and be suspended between the door bracket 19 on the door of device and upwards flow, and gets back to inlet 16.

Edge section 3 when not being frozen the article covering, provides bigger free cross section, and it only provides small resistance at cooling blast.Therefore, if the very most of of the surface of edge section 3 occupied by freezing article, then air-flow is not blocked significantly.
