Definitions
- the present invention relates to the rapid freezing of food, and more particularly in the household or hotel sector, providing the possibility of freezing in the most desirable manner, to obtain a quality frozen product.
- the device according to the invention overcomes this drawback by simply using a conventional refrigeration unit used to operate a common type freezer or fridge-freezer, this group cools a cold storage battery, which, when required, restores thus being able to produce a large amount of cold in a very short time.
- the solution provided by the present device resides in the use of air cooled simultaneously by the evaporator of the device and by a cold storage battery, itself previously cooled by said evaporator, this air is drawn from inside a quick-freezing compartment.
- the device according to the invention comprises, a refrigeration unit of conventional type, one evaporator of which is placed in a chamber called “cold accumulation chamber”, inside this chamber are also placed cold accumulators.
- the assembly communicates with a quick-freezing compartment in which the air cooled simultaneously by one evaporator and by the cold accumulators is drawn by fans or the like.
- Figure 1 shows in section, the device according to the invention. With reference to this drawing, this device comprises a compartment here called “cold storage chamber", it is located according to the preferred embodiment shown in the drawing, at the bottom of the cabinet, behind the freezing compartment occupying the entire interior width furniture (1).
- evaporator (2) of the refrigeration unit Inside this chamber are housed the evaporator (2) of the refrigeration unit as well as two cold storage batteries fixed on each side of the evaporator (3) and (7) (here, eutectic plates whose solution is dosed so as to obtain a eutexia point at approximately minus 30 degrees Celcius).
- the present invention does not limit the kind of product used to constitute cold accumulators or the degree of temperature at which these accumulators can give their maximum efficiency.
- This cold storage chamber communicates over its entire width via a duct (4) with the upper bottom of the compartment reserved for rapid freezing (5).
- a series of fans or the like is placed in said duct (9) having the function of drawing the air coming from the cold storage chamber in the rapid freezing compartment (5).
- this air after having cooled the product stored in the rapid freezing compartment, exits through the opening made at the bottom bottom and over the entire width of said compartment in (6), to re-enter the cold storage chamber, this air then cools on contact with the storage battery (7) and the evaporator (2) then passes through the passage located in the lower part of the cold storage chamber (8) and rises along the accumulator battery (3) while continuing to cool on contact with it and with that of the evaporator.
- the envelope of the cold accumulators is provided with corrugations in order to offer a maximum of surface to allow a maximum of exchange of cold.
- the same evaporator cools the freezing compartment (10) through the wall (11) which has inside, an insulating material so that the cold from the cold storage chamber (which is here the order of minus 30 degrees approximately) is attenuated in the freezing compartment, which does not require such a low temperature for the preservation of food.
- the air cooled by the cold storage chamber enters the freezing compartment through a duct which passes through the wall (11) which is provided with a solenoid valve controlled by a thermostat placed in the freezer compartment.
- a grid is arranged at (12) to prevent food projections from obstructing the conduits (4) and (6).
- the door of the rapid freezing compartment is at (13) and that of the freezing compartment at (14).
- the defrosting of the cold storage chamber as well as of the rapid freezing compartment is obtained in a nonlimiting mode by heating cables fixed between one evaporator and the cold accumulators, its operation is ensured automatically by the control means. and conventional detection, which simultaneously activate the fans and lock one solenoid valve of the wall (11) for the duration of the defrost.
- the bottom of the cold storage chamber has a low point and the elements commonly used for the evacuation of defrost water.
- a switch not shown here is fixed within easy reach of the user, it is controlled by a timer which will be set beforehand by the user according to the time necessary for the rapid freezing of the products stored in the rapid freezing compartment, (A manual giving the times necessary for the rapid freezing of the product is provided for user information.) Said switch causes the fans to start and simultaneously the forced operation of the refrigeration unit for the time determined by the timer, after which , the refrigeration unit is controlled by conventional detection devices placed in the cold storage chamber and adjusted according to the desired degree of cold.
- a temperature detection and regulation device such as, for example, a thermostat installed in the storage chamber cold.
- This device can be powered by an independent refrigeration unit or by a group also comprising a second evaporator for cooling a positive temperature compartment which then includes the traditional regulatory elements specific to devices at two temperatures (positive and negative).
