DE19505067A1 - Cold chest with partitions to protect against heat - Google Patents

Abstract

A cold chest for domestic and industrial use has operating modes that optimise energy usage and give effective heat protection. It also contains supplementary thermoelectric cooling elements for base load operation and transparent movable partitions. When the cold chest is open, the compartments inside (which lie on top of each other) can be protected from intruding warm air. They are made of thermal material, provided with seals and insulation. Variants of the partitions can be rotatable, tilting or sliding plates and are locked in place by magnets. There can also be foil types which are flat, folded, Venetian blind-like or roller blind-type.

Description

The invention relates to a refrigerator with thermal insulation for domestic and commercial energy-optimized use.

This refrigerator should initially be equipped with thermoelectric Peltier / cooling elements permanently provide the basic cooling load, however master the peak load operating conditions in future.

The multi-segmented created room divisions ensure you minimal air / heat exchange from the environment to the stored Refrigerated goods.

Compact designs are like the additional retrofittable ones Constructions that are as light as possible from a hygienic point of view designed to be removable and replaceable.

It is known that for the partial fulfillment of this task the opaque refrigerator fridge subconsciously finds use.

Furthermore, this applies to freezers from the drawer and through Door arrangements is made.

The invention is generally based on the object that constructive through a combined use with cooling elements speed of the cooling units should be reduced.

Furthermore, that with each refrigerated goods removal a very limited Air exchange enables relatively precise determination and control can be.

This object is achieved in that initially in the combined operation of the cooling unit / element, the range of Base and peak load via design-based energy-saving Division of labor becomes manageable.

Furthermore, that different performance cooling elements continuously as well as block by block in connection with an improved In future, thermal insulation will require an energy-reduced unit Carry out cooling operation.

Furthermore, that individually usable enclosed interiors stored refrigerated goods bacterially, thermally and air technically from Protect external environmental influences more optimally.  

Rigid interchangeable and functionally movable partition elements thus ensure passive and active bacteria / and heat protection.

The latter is mainly influenced by the transmission and ventilation certainly. The door is permeable to joints as well special attention is paid to the heat extraction of the refrigerated goods.

The air exchange of the interior, however, is energetic Though meaningless calculations or balance sheets, additional ones Insulated air layers, on the other hand, could be used for an energy-saving Cooling operation with new cooling technologies can be decisive.

The achievable advantage of the invention is in principle in that Improvement not only of the theoretical, but above all of operator-dependent energy consumption itself.

Some embodiments of the invention are in the drawings when the refrigerator is open with its superimposed Interiors are shown and are described in more detail below described:

Figs. 1 shows an open refrigerator with slidable screens - the sequence of numbers referred to in the side view to represent the magnetic polarity in a breakpoint:

1 magnet on the lower edge of the partition (possibly a sliding slot)
2 Magnet on the top edge of the separator attracting in opposite polarity
3 common holding magnet attached in / on the housing
Repulsive magnets 1 to 3
and 2 to 3 attracting gives better effect.

A single-acting roller blind variant is presented in FIG. 2 and a roller shutter system with an indicated magnetic holding by means of the above-mentioned magnetic polarity principle 2 + 3 is shown in FIG. 3 as an example.

Fig. 4 shows an overall view in addition to the Principle presen- tation of a group lock (with hidden magnet holder) in the upper refrigerator area, the electrothermal cooling element (according to Peltier) initially primarily to cover the basic cooling load.
