Definitions

  • This invention relates to a refrigeration appliance, such as a domestic refrigerator, freezer or the like, comprising a plurality of compartments with their own access apertures closed by usual doors, one of said compartments being advantageously of the convertible type with controlled temperature and being connected via a pipe to a pumping member for generating vacuum in said compartment.
  • Refrigeration appliances such as refrigerators, of the stated type in which vacuum is generally generated within the entire compartment or in a box member provided with its own lid or closure element have been known for some time.
  • the known constructions are often ineffective because of the inevitable seepage of air into the compartment, with consequent breaking of the vacuum
  • this seepage is prevented by locating a box member with its own lid inside the compartment.
  • this method is more costly than the first and comprises means, often not of simple construction, for opening the lid when the compartment door opens.
  • An object of the present invention is to provide a refrigeration appliance of the aforestated type which is of simple construction and low cost.
  • a further object is to provide a refrigeration appliance of the aforesaid type in which vacuum is reliably obtained in a compartment thereof.
  • a further object is to provide a refrigeration appliance of the aforesaid type in which by opening said compartment the vacuum therein is automatically broken, said opening being achieved without requiring particular force by the user.
  • a device of the stated type characterised in that a box member open on one side is removably contained in at least one of its compartments and is at least to a limited extent movable in a guided manner along walls of said compartment, the box member comprising an internal cavity arranged to communicate with the pipe connected to the pumping member via connection means, at the aperture of said box member there being provided means for its sealed closure supporting stiffening means arranged to lie against the cavity of said box member in which the vacuum is generated.
  • an upright refrigerator is indicated overall by 1 and comprises a cabinet 2 insulated with a usual insulating material (such as polyurethane) 3 and comprising three compartments 4, 5, 6. These compartments have their own access apertures 4A, 5A, 6A closed by corresponding doors 7, 8 and 9; said compartments are specifically a usual freezer compartment 4, a refrigeration or preserving compartment 6 and a convertible compartment 5 able to be used at variable but controlled temperature, for example close to 0°C or to the temperature of a freezer compartment (-18°C).
  • a usual insulating material such as polyurethane
  • a pipe 10 connected to a usual pumping member (not shown) for creating vacuum.
  • the pipe 10 is associated with a deformable member or sucker 11 arranged to cooperate with a box member 13 removably contained in the compartment 5.
  • the box member 13 constructed of a mechanically strong material (such as metal), comprises side walls 14, a rear wall 15, a top 16 and a base or lower part 17.
  • the rear wall 15 comprises a through hole 18 to connect the interior cavity 20 of the box member 13 to the sucker 11 and hence to the pipe 10.
  • Said cavity is open on that side 22 thereof where the door 8 is provided.
  • the box member 13 comprises, externally on its side walls 14, wheels 25 (such as ball bearings or wheels of anti-friction material) movable within guides 26 associated with side walls 27 of the compartment 5. Said movement is limited by bosses 30 provided on the roof 31 and/or on the bottom 32 of the compartment 5, and with which corresponding axially movable elements 33 cooperate against the action of a spring 35.
  • wheels 25 such as ball bearings or wheels of anti-friction material
  • each element 33 comprises a substantially annular body 36 having a cavity 34 containing a substantially T-shaped pin 37.
  • the head 38 of this latter cooperates with an annular edge projecting into the cavity 34.
  • the pin is fixed in known manner to the outside of the top 16 of the box member 13, the spring being mounted about it to cooperate with said top and with the body 36.
  • the box member 13 supports guides 40 within which there slide wheels 41 (wheels of anti-friction material or ball bearings) of a usual basket 42 contained advantageously removably in the box member 13.
  • the basket 42 is rigid with that side 43 of the door 8 which faces the open side 22 of the cavity 20 and is arranged to seal this latter.
  • a member 45 of a material of high mechanical strength comprising an end edge 46 arranged to cooperate via a seal member 47, maintaining vacuum in the box member 13, with a flanged edge 49 of this latter arranged in a relative seat 50 provided in a position corresponding with the compartment 5.
  • one of said edges 46 cooperates with a microswitch 51 positioned to correspond with the flanged edge 49 of the box member 13 and connected to a usual control circuit (not shown) for the pumping member.
  • the door 8 (formed in the usual manner with a plastic structure 53 into which polyurethane or another insulating material 54 is injected and with which the member 45 is rigid) carries usual magnetic gaskets 57 ensuring the thermal seal of the compartment.
  • the door 8 is pulled to separate it from the cabinet 2.
  • the box member 13 is returned into contact with the sucker 11 and the microswitches 51 close. In this manner, if the operating pushbutton for the pumping member is again pushed, the pumping member immediately operates to create vacuum in the box member 13 to help to hermetically seal the door 8 against the cabinet 2.
  • the box member 13 can be extracted from the compartment 5, for example for cleaning. To achieve this, the box member has to be pulled directly with the door open, to overcome the resistance of the springs 35 against which the elements 33 move.
  • the microswitch 51 is positioned on the rear wall 5K of the compartment 5 (as shown by dashed lines in Figure 2 and indicated by 51K). It cooperates with the box member 13 on opening and closure of the door with resultant movement of the box member 13 along the guides 26.
  • a fixed stop 5H (indicated by dashed lines in Figure 2) is associated with the rear wall 5K of the compartment 5, and against which the box member 13 halts when the door 8 is opened.
  • the bosses 30 and elements 33 can be omitted.
