Description

Refrigerating unit as an attachment for two refrigerated bunkers.

The invention relates to a refrigerator as an attachment for two refrigerated bunkers that have their backs facing each other.

In supermarkets and markets in the that are sold groceries are used refrigerated bunkers for Save perishable goods. In the field of bunkers fridges distinguishes between freezer bunkers, which they maintain a state of freezing, and the refrigerating bunkers of positive temperature, in which the goods are stored at temperatures above zero. The concept of "chest refrigerator "is used here for both types of bunkers, which means that the invention makes no distinction between both groups Rather, the invention is applicable to both freezer bunkers like temperature refrigerated bunkers positive.

The use of refrigerated bunkers is linked to a high level of space occupation, usually running out of Use the space on top of a refrigerator chest. This is especially valid for freezer bunker blocks, in those who stand against each other two freezer bunkers back to back. The space above the Freezer bunker blocks are left unused.

The invention pursues the purpose of creating a refrigerator that can be used in combination with two refrigerated bunkers that are placed back to back and allow a profitable use of the space that exists above the refrigerating bunkers.

The invention is defined by the characteristics of claim 1. According to it is provided an easel that is arranged between both refrigerated bunkers and carries a refrigerator cabinet that contains two cold rooms that stand out above the refrigerator bunkers, as well as a refrigerating machine that is common to both cold rooms.

The invention offers the advantage that the cabinet Fridge is accessible by two opposite sides and contains two cold rooms, but only a single refrigerating machine. The circumstance that the refrigerator cabinet has a machine refrigerator means that cold is not produced in one location remote away from the refrigerator and is not contributed to the furniture Fridge through cold transport pipes. Rather the refrigerator cabinet is a refrigerator that is "ready to plug in, "which is enough to connect with a plug electric to the usual outlet. This way you have a high level of flexibility in terms of readiness and mobility of the refrigerator cabinet. The refrigerator cabinet serves as an attachment superimposed to expand the assortment of frozen items without it is necessary to occupy an additional area of the premises commercial. In general only one easel is necessary for both cold rooms that protrude sideways mutually opposite. Thanks to this, the weight is also balanced of the refrigerator cabinet. The easel does not necessarily have to Submit a single column. Said easel can also be provided with several columns that are joined together by a beam. The important thing is that the easel is arranged in the plane middle of the refrigerator cabinet, so that it protrudes between the refrigerated bunkers. The easel does not cause it practically any discomfort in the face of the use of Refrigerating bunkers and refrigerator cabinet.

According to a preferred configuration of the invention, between the cold rooms a chamber is provided of distribution that has exit openings that give both cold rooms and establish communication with them. The distribution chamber is used to distribute to both cameras fridges adjacent to the cold air that has been produced by the refrigerating machine The introduction of cold air also has place through the back wall of each of the cameras.

Preferably, the distribution chamber It contains at least one evaporator of the refrigeration unit. This has the advantage that cold air is produced directly in the chamber distribution and do not have to cover large routes to get to the destination point Thanks to this, losses are minimized of cold. Two-stage refrigeration can also take place, the last stage must in any case take place in the chamber of distribution.

According to a preferred configuration of the invention is provided to be arranged on each side of the distribution chamber at least two cold rooms that present each your own door. This way they are not directly transmitted to the adjacent cold rooms the repercussions that are caused by the opening of a door in a cold room The cold rooms certainly have a common cold source, but different extraction openings with Your own doors. These cold rooms are essentially thermally isolated from each other.

The easel can have feet that protrude in the direction of mutually opposite sides below of the refrigerated bunkers that are placed on their supports. This allows stable positioning of the stand, without that additional space is needed. It is not particularly necessary provide a foundation for the easel on the ground.

In a specific embodiment of the invention is arranged on one side of the refrigerator cabinet a machinery compartment containing the compressor of the refrigerating machine with the corresponding motor drive

The refrigerator cabinet can be provided with an equipment that facilitates handling and maintenance. So, one pressure pipe leading from the compressor to the evaporator can heat a collecting bowl in which the collection is collected and evaporated condensation water that forms in the evaporator. A pipe of pressure leading from the compressor to the evaporator can also constitute a heating device for heating the gaskets of the doors.

It is clarified below in more detail a preferred embodiment of the invention with reference to the drawings. This exemplary embodiment describes a solution. preferred, but should not be understood as something that limits the scope of the protection that is sought.
