Definitions

  • Temperature cooler for rapid cooling and/or rapid freezing of products to be stored at low temperature for domestic use
  • the present invention concerns a temperature cooler for rapid cooling and/or rapid freezing of products to be stored at low temperature .
  • the coolers in question conventionally use a powerful refrigerating plant capable of performing the rapid cooling or rapid freezing, to the core , of the food products introduced into an insulated compartment .
  • the refrigerating plant and the compartment are generally designed with dimensions such as to ensure the so-called "core" cooling of a food product roughly from a starting temperature of about 70 °C to a temperature of about 3 °C in a time period of no more than 90 minutes .
  • the refrigerating plant and the compartment generally have dimensions such as to ensure core freezing of the said product to a temperature of about -18 °C in a time not greater than about 4 hours .
  • the power levels installed are consequently considerably greater than those envisaged in conventional refrigerating plants intended for the conservation of the refrigerated or frozen product .
  • plants with evaporators , fans and relatively large-size condensers for circulation of large air flows are used .
  • coolers are intended for collective catering services , such as restaurants , refectories and food or pastry workshops , where the size of the support structure of the cooler is relatively unimportant .
  • they improve to such an extent the conservation capacity of the food products that there has also been a demand for them in smaller environments , such as domestic environments .
  • the compressor and the condenser are , as is known, preferably positioned above (or below) the insulated compartment , while the evaporator with the associated fan are preferably positioned inside the compartment itself .
  • Adopting this constructional criterion penalizes in particular the aesthetic appearance of the cooler since the fins of the condenser are arranged visibly in the front part thereof in the manner of partition from the external environment so that they are passed through by the air sucked in by a fan situated between them.
  • Temperature coolers of the known type are unable to satisfy the market requirements , such as those typically of a "family" environment and those for example of a small food workshop , since they excessively impair the aesthetic appearance of the furniture inside which they are fitted .
  • the main object of the present invention is to provide a temperature cooler which is able to satisfy, on the one hand, the requirements typical of the dimensions associated with built-in furniture , without adversely affecting the thermo- technical performance , and allow at the same time a configuration of the cooling plant able to satisfy the most demanding aesthetic and hygiene requirements .
  • a further object of the present invention is to provide a cooler which is constructionally simple and inexpensive to produce and operationally entirely reliable .
  • Figures 1 and 2 are partially sectioned side views , with some parts removed so that other parts are more clearly visible, of a temperature cooler constructed in accordance with the present invention and shown with a flap arranged in two different operating positions ;
  • Figures 3 and 4 show a view, on a larger scale , of Figures 1 and 2 , respectively;
  • Figure 5 shows a front view of the cooler according to the present invention .
  • the temperature cooler according to the present invention has been denoted in its entirety by 1.
  • the support structure 2 has a substantially box-like form and is provided with facing side walls L, L' , with facing front and rear walls A and P, respectively, and with facing top and bottom walls S and I , respectively, the latter wall optionally being provided with support feet .
  • the support structure 2 contains internally an insulated compartment 4 inside which an access opening removably closed by a door 6 is formed .
  • the compartment 4 is also defined in a conventional manner by an end wall , facing the opening, by a pair of side walls , by a ceiling and by a base .
  • the side walls have , formed in them in an entirely conventional manner, guides for supporting a grille in turn intended to support trays , pans or other containers for the food to be cooled .
  • the cooler comprises a ventilation unit and a cooling plant which do not form the subject of a specific claim.
  • the compartment 4 has , arranged above it , a part of the cooling plant composed of the compressor 3 and the condenser 5.
  • the latter is provided with a plurality of heat exchange fins 7 which are arranged in the vicinity of the front wall A of the cooler 1 and are passed through by a flow of air sucked in by a first electric fan 11 situated behind the condenser 5 immediately adj acent to the fins 7.
  • a chamber 9 is formed, with a housing, inside the compartment 4.
  • This chamber 9 is separated by partition 10 into two parts , one which houses an evaporator 12 and the other one which houses an electric fan 11 ' able to force the air of the compartment 4 through the evaporator 12 in order to cool or freeze the products .
  • the electric fan 11 is designed with dimensions suitable for the air flows required in a temperature cooler, in the case in question for example for a flow of about 500 m 3 /h.
  • the refrigerating plant is similarly designed, in relation to the dimensions of the compartment , with an electric compressor having a power, for example , of about 500 Watt .
  • the cooler 1 comprises a movable flap 13 which is mounted on the support structure 2 along the front wall A so as to removably close the front area occupied by the fins 7 of the condenser 5.
  • the flap 13 is actuated by actuating means 14 described in detail below so as to move between an operating position 15 , shown in Figures 1 and 3 , where it is raised from the fins 7 of the condenser 5 so as to allow the intake of air, and a non-operative position 16 , shown in Figures 2 and 4 , where it is arranged so as to cover the fins 7 when operationally no air intake is envisaged, for example when the cooling plant is not functioning .
  • the movable flap 13 has the form substantially of a parallelepiped with a rectangular front side and is hinged frontally on the cooler 1 on its upper side 17 so as to rotate rotatably about an axis Y parallel to the front wall A of the cooler 1.
  • the actuating means 14 comprise at least one arm 18 having a first end 19 connected to the movable flap 13 so as to cause raising or lowering thereof about the axis Y, and a second end 20 connected to a cam 21 actuated by a motor 22.
  • the first end of the arm 18 has , mounted thereon, a magnet 23 for connection to the inner surface 24 of the movable flap 13 which is specially made of treated steel or some other metal able to be attracted by a magnet .
  • the magnet 23 is preferably formed by two rings of magnetized neodymium
  • the presence of the magnet 23 ensures a reliable connection of the arm 8 to the flap 13 so as to cause the movement of the latter and at the same time allows the flap 13 to be raised completely, separating it from the arm 18 , so that it is possible to clean behind the flap 13 itself the corresponding fins of the condenser which require periodic cleaning and maintenance .
  • the end-of-travel positions are ensured by a switch 25 which is operated directly by the profile of the cam 21 on which it rests by means of a lever 26.
  • the flap 13 forms in a non-operative position a continuous surface with the door 6 of the compartment , which is in an adjacent position underneath the flap 13. This allows the cooler 1 , once it has been designed with its support structure suitable for built-in mounting inside a piece of furniture, to be incorporated in an aesthetically pleasing manner in a kitchen environment , in particular forming visible surfaces which are substantially flat .
  • the support structure 2 may for example be designed with dimensions suitable for possible built-in mounting inside kitchen furniture, for example with a width L of 560 mm and a depth P of 549 mm.
  • the compartment 4 with the abovementioned dimensions allows the core cooling, to a temperature of about 3 0 C in a time period not greater than about 90 minutes or core freezing to a temperature of about - 18°C in a time period not greater than about 4 hours , of a food product which has an initial temperature of about 70 0 C .
