DESCRIPTION

OF THE INDUSTRIAL INVENTION WITH THE TITLE:

Refrigerators, freezers, cold rooms with multifunctional built-in vacuum system.

PRIOR STATE OF THE ART

To avoid the rapid deterioration of food, households make extensive use of refrigerators, while to extend the life of food stocks they use vacuum-sealed containers and bags, cold rooms and freezers. In addition, equipment is used to suck the air from the containers and store vacuum-packed foods, while supermarkets and agri-food companies sell some products already in vacuum packaging; this is to prevent the permanence of the air and its contact with food which facilitates contamination, reduces their duration and freshness,

Vacuum-packed products, of course, have higher costs and are often packaged at home using special containers and bags from which the air is extracted, especially before freezing them to reduce their volume, but also to extend the storage of food placed in the refrigerator.

In the sector of the refrigeration industry for food, much progress has been made, especially as regards energy savings and the rationalization of internal spaces and containers, but no innovations have been adopted to easily expel the air from inside the refrigeration equipment, to extend the life and conservation of food; that is, there are no refrigerators with their own "vacuum compartments", although it is known that the oxygen contained in the air releases the so-called free radicals that contribute to the aging and deterioration of vegetables, meat, fish, and foods in general.

This project aims to make up for this deficiency, by providing for the construction of refrigerators and freezers capable of expelling the air contained within them, as soon as the main door or the door of its various sectors is closed, to achieve the aforementioned purposes.

The residual air suction system inside the refrigerators and freezers can also be used for other domestic uses; for example to suck air from laundry containers, pillows, duvets, etc., to reduce their volume and contain the clutter spaces of the wardrobes, when they have to be stored in the changing seasons.

OBJECTIVE THAT INNOVATION INTENDS TO ACHIEVE This project intends to spread and facilitate the vacuum preservation of food and similar products, even short-term ones, to facilitate the work of housewives, to reduce energy waste (avoiding refrigerating the air that enters the refrigerators and freezers when they are opened) and above all to extend the storage times of food, avoiding waste and saving families who need it so much. This with the use of the already existing technique that provides for the suction of air from bags equipped with valves, which can be easily applied and useful in refrigerators and freezers, to increase the shelf life of food in a practical way (without having to prepare them in individual bags) and quick as it will not be necessary to divide the food to be vacuum packed, and inexpensive, also due to the multi-functionality of the air suction system.

ANALYSIS OF THE RESULT ACHIEVED

The innovation in question will allow you to quickly and easily vacuum all the foods in the refrigerator or freezers, without having to divide them by species and without preparing many individual bags. The system will facilitate the work of housewives, reduce energy waste (as it will not have to refrigerate the air that enters when the refrigerators and freezers are opened) and above all the storage times of food will be extended, avoiding waste and saving customers.

The system will also allow other forms of domestic use, for example to suck air from any bag with valves, such as those where clothing, blankets, pillows, etc. are stored, to reduce their volume and encumbrance when stored in end of the season.

Claims (1)

CLAIMS OF THE INDUSTRIAL INVENTION WITH THE TITLE: Refrigerators, freezers, cold rooms with multifunctional built-in vacuum system. The present project for industrial invention claims an air suction system present inside refrigerators, freezers and food and similar containers in order to prolong their conservation, facilitate the task of housewives, contain the overall dimensions and increase the capacity capacity. , and also to reduce electricity consumption. The air intake can take place with an automatic system or with manual control. The use of the system is also claimed for other uses, even of an industrial type and / or relating to the transport of goods that require a stabilized and controlled temperature, such as ice cream, perishable foodstuffs, fruit, etc., (to improve their conservation during transport and distribution), as well as for domestic uses, such as air extraction from laundry containers and bags, blankets, pillows, etc. In a nutshell, the use of an automatic or manually controlled suction system is claimed for the residual air inside the refrigerators, freezers, cold rooms and relative compartments, etc., after their closure, to obtain refrigerators and freezers. in which to store food and the like like a large "vacuum" that can be opened and closed automatically and suddenly, to improve the duration of their conservation, to speed up the work of housewives, as well as to reduce the condensation that forms in household appliances and to save energy, safeguarding the environment and producing savings for users. The system can be applied to the entire refrigerator, freezer, etc., and also to the sub-compartments built inside them. The system consists in applying to refrigerators, freezers, etc., an air suction device whose technique and function is similar to that used to store products under high vacuum, to increase the duration and quality of conservation; that is, the air is extracted to prevent food from oxidizing and deteriorating due to the free radicals that are released from oxygen. The technique involves using an air suction device equipped with ducts connected to the refrigerator compartment, freezer, etc., or with their hermetically sealed compartments and containers equipped with a valve and suction duct, which will operate manually or automatically by closing the door of the appliance or the lids of the containers, so as to expel the air from inside them, as soon as the appliance or the compartment is closed. The suction device can be located in any position, as long as it is functional. The air intake from the container will last until it is exhausted. APPLICATION EXEMPLIFICATION If you use single compartments for vacuum use, these must be equipped with a special valve and relative duct to be able to suck the air inside them and must be watertight, to prevent the air from returning inside the appliance afterwards. principal. The suction can be automatic, that is, with an impulse activated by closing the container, or by manual impulse for each vacuum compartment present in the appliance. To use a single suction device, it must be equipped with several suction pipes, connected to all the containers to be vacuum-sealed. While to avoid blocking the lid of the various vacuum compartments, an air inlet valve must also be provided, with controlled operation, to allow the lid to be lifted when it is necessary to open them. The same applies if you empty the air from the entire appliance, to avoid blocking it. To optimize the use of the containers, it is possible to equip more lids to create sub-compartments; the lids will be watertight, flexible or elasticized to support and favor the air intake and thinning of the vacuum products as much as possible; the lids can also slide inside the guides obtained inside the container. To use the suction system for other domestic uses (for example for the suction of clothing containers) these must be equipped with special valves that can be adapted to the pipes of this suction system.
