Definitions

  • the present invention relates to a refrigerated drawer structure with forced air cooling, for preserving foodstuffs at low temperature, of the type that can be fitted in a cabinet.
  • U.S. Pat. No. 5,657,639 describes an invention of refrigerated drawers in which a means for generating cold air directs said air through supply ducts towards the drawers.
  • a means for generating cold air directs said air through supply ducts towards the drawers.
  • Patent FR 2,797,684 discloses a refrigerated drawer in which a module containing the compressor-condenser assembly is introduced into one compartment of a cabinet.
  • the drawer is fitted in an insulated cavity, on the bottom of which there is arranged a evaporator facing towards a radial fan that conveys the cooled air into the drawer.
  • This solution has the disadvantage of a loss of depth of the refrigerated drawer in that the rear part of the module is occupied by the compressor and the associated cooling fan.
  • the manner in which the cold air is introduced into the drawer does not ensure rapid cooling of the food products, particularly when the drawer is fully loaded, because the stream of air passes over the top of the drawer space without penetrating therein.
  • the present invention addresses and solves these problems by providing a refrigerated drawer structure having the features listed in the appended claims.
  • FIG. 1 shows an exploded view of the overall refrigerated drawer structure of the present invention
  • FIG. 2 shows a sectional side view of the refrigerated drawer structure illustrated in FIG. 1 ,
  • FIG. 3 shows a sectional front view of the refrigerated drawer structure illustrated in FIG. 1 from the drawer opening side
  • FIG. 4 is a larger scale view of a detail from FIG. 3 .
  • FIG. 5 shows a vertical sectional view of the refrigerated drawer structure illustrated in FIG. 1 seen from the rear side relative to drawer opening.
  • FIGS. 1 to 5 show an example of a refrigerated drawer structure for preserving foodstuffs at low temperature, which can be used within a cabinet, said structure being made up of a module 1 containing a drawer 6 , to the outside of which is attached a frame 7 for supporting the compressor 9 and the condenser 10 of the refrigeration circuit.
  • the module 1 of the drawer can be broken down into various parts 1 a , 1 b and 1 c to facilitate assembly thereof [and] comprises an air space with insulating material (not shown in the drawings) which thermally insulates a compartment V for accommodating the drawer 6 away from the external environment, and spacers D for supporting the compartment V within the module 1 .
  • the compartment V of the drawer comprises an evaporator 2 of the refrigeration system positioned on the front internal wall on which is located a shaped protective cover 4 , the shape of which determines circulatory flow within the drawer.
  • the shaped cover 4 has a central opening 4 a for supplying cold air into the compartment of the drawer and one or more openings 4 b on the lower side for recovering the air.
  • an axial fan 3 to drive the circulation of air within said drawer with the aim of uniformly cooling the articles contained therein.
  • the drawer 6 of the module V runs on two guides 5 a and 5 b applied to the inside of the insulated compartment and comprises a rear wall 6 b equipped with a central lowered portion R of the rear wall in line with the cooling air supply opening 4 a , in such a manner as not to obstruct the introduction of air into the drawer 6 , when the latter is in the closed position.
  • the lowered central portion R of the rear wall 6 b it is possible to use a shaped hole; furthermore, the lowered portion can involve the entire rear wall 6 b.
  • the drawer 6 comprises within it devices K in the form of bars 7 capable of preventing the obstruction of the cooling air supply channel 4 e due to the positioning of articles in the vicinity of said channel. Said devices K prevent the positioning of articles, over the entire length of the drawer, so creating a preferential channel for the flow of cold air circulating in the drawer, which is particularly effective for more rapidly cooling the articles arranged within said drawer.
  • the drawer 6 constitutes the closing element of the refrigerated module, being equipped with a front panel 6 c of thermal insulation, and a sealing gasket 6 d that prevents air from escaping from the compartment V, when the drawer is in the closed position.
  • the drawer 6 is provided on its front side with a decorative panel 6 e matching the cabinet in which the refrigerated drawer structure is to be used.
  • the refrigerated drawer structure is equipped with a control 13 for controlling the temperature of the internal environment, is also provided with a sensor for detecting opening of the drawer and an actuator for stopping operation of the cold air supply fan such that the fan is switched off when the drawer is opened.
  • the compressor 9 and condenser 10 assembly of the refrigeration system is supported on a metal frame 7 outside the module containing the drawer 6 , and also includes a cooling fan 8 , with the aim of enabling the installation thereof within a cabinet (not shown).
  • the above-mentioned frame 7 is constructed such that it can be fixed to the module containing the drawer 1 in the rear zone of said module (above or below), so as to minimise the space it occupies within the cabinet, with the aim of permitting combined use with an auxiliary drawer (not shown) of reduced depth within said cabinet in which the structure is to be installed.
