Description

DESCRIPTION COOLER WITH A ROOM WHERE FOOD IS KEPT FRESH This invention is an electromagnetic device that allows food to be identified and kept fresh. It relates to a cooling device comprising a chamber with a heating medium.

In refrigerating appliances, different types of foods, especially raw foods such as meat, fruit and vegetables, conditions must be kept. Ideal temperature and humidity levels different for vegetables and meat products. In addition, to preserve their freshness, vegetables and exposure of fruits to electromagnetic radiation, preferably in the visible light range. must be dropped. On the other hand, meat products are in the visible spectrum. It is not directly affected by electromagnetic radiation, but in a relatively short time. may be corrupted. Therefore, meat products have sterilizing properties. It is vital to sterilize superficially using electromagnetic radiation. carries. Although special storage rooms exist in the art, such refrigeration appliances with storage rooms, stored in said room has the ability to detect food and act according to the type of food stored is not.

Patent numbered USZOO7104841A1 in the state of the art A household appliance with a container in which vegetables are kept fresh. is explained.

The object of this invention is to insulate vegetables, fruit, insulated from the remaining area of a compartment. and where food such as meat is stored, the type of food in it is identified, and the by means of lighting in the form of electromagnetic radiation, which varies according to the The subject is the realization of a cooling device in which the freshness of the food is preserved.

The first claim and this will, which are carried out to achieve the purpose of this invention The cooling device described in the dependent claims is a body, the largest it comprises a small compartment and a door providing access to the inside of the compartment. door, at least it is fixed to the body in a rotational manner by means of a hinge.
