DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a kitchen unit for the handling of portions of household garbage at the source, i.e. in the individual households, said kitchen unit being in the form of a box, preferably a module, which fits into a kitchen table.
The invention also relates to the use of said kitchen unit for the handling of portions of household garbage at the source, i.e. in the individual households, whereby with said use the household garbage is divided into two portions.
Out of regard for the environment, it must be seen to be an objective to re-use organic kitchen garbage such as potato peelings, meat leavings and similar materials as fodder, for example for pigs and other domestic or breeding animals. In addition to organic garbage, the sorting at the source also includes paper, glass, cardboard, tin cans and plastic containers.
This makes it necessary for the garbage to be sorted at the source, which will be effective only if said sorting is made as easy as possible, which means that it must take place immediately in the ordinary household kitchens in connection with the preparation of foodstuffs.
Furthermore, the collection must be arranged in such a manner that it is not necessary for the housewife, for example in a multi-story apartment house, to go to a central collection point with even the smallest portion of garbage. This means that the possibility must be established of storing the garbage in the kitchen until a suitable amount of garbage can justify the inconvenience involved in transferring the garbage to the central collection point, in which case said transfer can be expected to take place only once or twice during the course of a week.
With a transfer which takes place only once or twice a week, there is the disadvantage that the organic material which is stored in a kitchen at around 20.degree. C. will begin to putrefy, the result being that it not only becomes unusable, but also that it starts to smell.


THE KNOWN TECHNIQUE

From EP patent publication No. 0 298 322, there is known a piece of kitchen equipment which consists of several compartments in which individual containers are placed to receive each their kind of garbage.
The individual container for the receipt of the organic material is placed in a cold storage box which is insulated against heat and can cool the garbage to a temperature of, for example, 5.degree. C. or less. Therefore, when stored for no longer than a week, the organic material will not start to putrefy and thus not be ruined.
However, there remains a disadvantage in connection with moist paper and cardboard which has been used for the packaging of foodstuffs, whereby the paper and the cardboard has been more or less soaked through by meat juices or has been defiled by fatty substances of different kinds, and can therefore begin to putrefy and to smell in the kitchen.
This putrefaction can be avoided if such packagings are dried so that there is no bacterial growth with subsequent putrefaction. A drying can be effected by the application of heat, but this requires energy without being economically expedient.


THE OBJECT OF THE INVENTION

With the invention it is desired to provide a kitchen unit of the kind disclosed in the preamble, in that with said kitchen unit the drying of the wet packaging can be effected in the most economical manner possible, and the storage can take place under such conditions that the used packaging does not start to putrefy, even when stored in a warm kitchen for longer periods.
The new feature of the invention is that the kitchen unit has a refrigeration circuit and a first heat insulated compartment which is arranged for the storage of a first portion of especially wet garbage which is intended to be cooled, in that the refrigeration circuit's evaporator is placed in said first compartment, and a second compartment which is arranged for the storage of a second portion of garbage which preferably has a low concentration of wet material, in that the refrigeration circuit's condenser or parts thereof are place
