Description

The Invention relates to a plug-in refrigerator and freezer, as a commercial refrigeration furniture primarily for the use in a food market for storage and presentation of fresh and frozen foods. The Chest is only connected to the existing electrical network. These chests will be back to back or one at a time Wall placed in blocks.

At present, ready-to-plug-in refrigerators and freezers, for example of the ART brand, are being installed in the discount area. Under www.aht.at (Supermarket Supermarket Chests), for example, a plug-in refrigerator and freezer Athens XL is offered. These chests work on the principle of an outer skin condenser and an inner container evaporator. In the foamed side walls of the chest are each Cu tubes for the liquefaction process (warm) and for the evaporation process (cold). The compressor, including the electrical system, is located in a compartment at the bottom right of the chest.

adversely is that the machine compartment arranged below a considerable Takes up space and reduces the internal volume of the chest. The refrigeration concept, the liquefaction and evaporation in selbiges insulating body (side wall of the Chest) has energetic disadvantages. Furthermore is an orderly automatic defrost of the chest in the filled Condition not possible. Furthermore, machine set and chest always firmly connected. As a result, a service must be provided Place expire and can not outside the store occur. Every single chest must have a compressor.

DE 20 47 445 A describes a heat-insulated container having a freezing or cooling device arranged at its one end, wherein the cooling part are arranged in a compartment inside the tub insulation of the container and the machine part in another compartment outside the heat insulation.

In DE 14 76 953 a freezer is described with a removable total cooling system, which is easily removable with the common housing, in which all parts are housed except for the evaporator, placed on a freezer with overhead opening.

DE 102 35 487 A1 describes a ready-to-plug freezer in which the evaporator, the condenser, the compressor and the refrigerant lines is designed as a common unit removable from the refrigerator.

all The three aforementioned solutions is common that a high technical complexity is required, since every freezer must have its own cooling technology.

task The invention is a plug-in refrigerator and freezer to propose with an automatic defrost function, which at a low apparatus engineering effort a better energetic Behavior and a high service friendliness possesses.

According to the invention the problem solved by the features of claim 1. Ausgestaltende features are in the dependent claims 2 to 4 described.

The plug-in refrigerator and freezer is in Block and / or wall installation with at least two consecutively or side by side arranged chest carcasses with thermally insulated Equipped walls. In block layout remains between the chest body backs an outboard Gap for an external condenser. In Wall installation is the external condenser behind the back of the chest in front of the wall. The external condenser For example, a lattice liquefier or a lamellar liquefier be. The plug-in refrigerator and freezer contains a separate cooling module for several chests. The cooling module has at least two spaced evaporator cassettes, with the gap between the evaporator cassettes is greater than the distance between the inner sides of two adjacent chests walls including their insulation. In each evaporator cassette is at least an evaporator and at least one fan included. Preferably several fans provided.

The Fans suck in the return air from the inside of the chest carcass a suction port and pass over cooled air a cold air opening back to the goods interior.

Above the evaporator cassettes is a receiving unit for a Cold block with at least one compressor and lines arranged for at least two evaporator cassettes. Here can also be housed the control and regulating equipment. Outside the evaporator cassettes is at least one external condenser intended.

The Cooling module is from the top of the walls of the chest carcasses plugged so that the evaporator cassettes within the Warenauslageraumes and the external liquefier respectively outside behind a chest back wall.

In block configuration, the external condenser is in a space between the evaporators arranged cassettes, which is then in addition to the wall thickness of the back-to-back adjacent chests correspondingly wide.

Of the External condenser can be demountable and in Transport position in the space between two juxtaposed Evaporator cassettes are arranged.

A Variant is that a cooling module with four evaporator cassettes for a chest of two next to each other and two behind each other arranged chests is provided.

Of the Chest body was completely from the refrigeration components separated and is in its function mainly Isolierkorpus. This Truhenteil can manufacturing technology in a completely separate process can be made for. B. via the rotational sintering process made of complete plastic. In this rotation hollow body is subsequently the insulating insulation material inserted, for example Styrodur plates. The chest carcass contains again all grooves and shapes to accommodate more plug-in modules.

following The invention will be closer to an embodiment explained. Show it:

1 Freezer fridge module before assembly

2 refrigeration module

3 Freezer with inserted cooling module

4 Cooling module in transport position

1 shows a plug-in freezer in a block of four before assembly.

Two next to each other and two successively arranged chest carcasses 1 have an insulation made of foam boards. All juxtaposed chest carcasses 1 stand with their side walls directly to each other. Behind one another stand the chest carcasses 1 not directly, but on separating gap 15 together. The separation gap 15 is dimensioned so that in between a trained as a lattice liquefier external condenser 5 Can give off heat to the environment. The chest carcasses are on top with a glass cover 12 Mistake.

This in 2 illustrated cooling module 2 has four evaporator cassettes 6 , one for each chest carcass. The gap 11 between the evaporator cassettes 6 is slightly larger than the distance of the goods facing inner sides of two adjacent chests walls. In every evaporator cassette 6 are an evaporator and four fans included. The fans suck the return air from the inside of the chest via a suction opening 8th and conduct cooled air over a cold air opening 7 again to the goods interior.

Above the four evaporator cassettes 6 is a recording unit 4 for a cold block with a common compressor for all four evaporator cassettes 6 intended. Furthermore, here the corresponding lines and the necessary control and regulation technology for the operation of the freezer are included. On the recording unit 4 is a removable cover 3 attached, which ensures constant access to the compressor. For the derivation of the compressor waste heat is an exhaust port 9 in the cover 3 intended.

Outside the evaporator cassettes 6 , in the space 10 between the four chests back, the housing is the external liquefier 5 intended. Four grids each with condenser fins are attached to the cold block and connected and protrude on both sides into the intermediate space 10 ,

The cooling module 2 is from the top of the walls of the four chest carcasses 1 attached. The evaporator cassettes 6 are located within the goods storage room.

In 3 is a built-in cooling module shown. On the space above the separation gap 15 to the right and left of the refrigeration module are each a separating gap cover 13 each with a grille 14 attached.

The external condenser 5 can be demountable and in transport position in the space 11 between two adjacent evaporator cassettes 6 to be ordered. This is in 4 shown.

The Advantages of the invention are that an improvement in the energetic balance is achievable, since a two or a four-unit always can supply several chest carcasses. There is a high degree of flexibility because the chest carcasses separated from the plug-in refrigeration unit are, with the same possibility, a plug-in design offer. The chest and the cooling modules containing the technical parts can be produced separately and only on site through Inserting the refrigeration unit are used. Because the evaporator is housed in a cassette and is no longer in the chest carcass the ice is not concentrated in the chest carcass. It can be defined in the separate cassette, where the evaporator can be defrosted targeted, without the goods must be cleared.

in the Service case could chest and refrigeration unit separated be replaced. In addition, offers at the chest an added value, since these are now equipped with a front glazing can be. The outer container will not work anymore needed for liquefaction.
