Definitions

  • the present invention refers to a refrigerator and/or a freezer provided with a compartment in which vacuum is produced by means of a vacuum pump.
  • a container closable in a vacuum-tight manner and able to be moved within said compartment, said container being provided with a pipe through which the vacuum is produced and which is arranged to cooperate with a counter-pipe provided in the usual cabinet of the refrigerator or the like and opening into a wall of said compartment, said counter-pipe being connected to the vacuum pump, at least one of the cooperating ends of said pipes comprising a hollow elastic element arranged to form a seal against the other end.
  • a refrigerator is disclosed with means for maintaining a partial vacuum in the food compartment including a suction pump to draw air out the same compartment and also to draw off odours; means are comprised which are automatic in their operation so that when the refrigerator is opened they will permit air to rush into the food compartment and raise the pressure therein to atmospheric pressure.
  • the whole food compartment and not only a separate container, different from said compartment, is subjected to the vacuum operation so that, if the user wishes to store the food in the refrigerator compartment without subjecting it to the vacuum, this way of operation is impossible to be achieved.
  • the handle to open the door is associated to a mechanism, to let the air into the compartment, which is complicated and burdensome.
  • a food storage and preservation system showing a plurality of food storage containers each having related door, related vacuum associated devices, and a centralised air treatment module comprising a vacuum pump and switch sensor that activates when a container door opens or closes; this food system is created to stay both inside or outside of a refrigerator.
  • a refrigerator which comprises a vacuum cabinet, which includes a vacuum compartment and an open top drawer in the vacuum compartment.
  • the suggested solution is basically well known in the art, with the adding of a timer, operated by the door closing, and automatically controlling the vacuum pump operation.
  • Said refrigerator suffer the drawback that the venting means to the atmosphere comprise a pushing valve that has to be operated manually each time the vacuum compartment is pulled out; this operation may be uneasy and also may be often forgotten, thus not making the vacuum compartment user friendly.
  • a refrigerator which comprises a vacuum cabinet which includes a vacuum compartment and a drawer in the vacuum compartment, said compartment being associated to a related top lid; even in this case the vacuum compartment is complicated both to be produced and to be operated, as the lid has to be automatically disengaged while the drawer is pulled-out, and remains inside the refrigeration compartment, while the drawer stays outside it. All that implies complicated mechanical means as especially showed in the figures 3 and 4 of the relevant patent.
  • a refrigerator according to the preamble of claim 1 is known from US-A-2894845 .
  • An object of the present invention is therefore to provide a refrigerator or the like comprising a movable container internally under vacuum, which obviates the drawbacks of known constructions.
  • a particular object is to provide a refrigerator with a vacuum container type where the operation of the vacuum valve is controlled by the same handle used to open/close the door.
  • a further object is to provide a refrigerator of the aforesaid type, where the same handle is also used to operate the vacuum pump according to the same handle operation.
  • Another object of this invention is to arrange such type of refrigerator so as, alternatively from the just given solutions, said vacuum pump and/or said vacuum valve are operated by the closing movement of said drawer into said box.
  • a refrigerator or freezer comprises a cabinet 1 containing a refrigeration compartment 2 and a freezer compartment 3, each provided with its closure door 4 and 4a, respectively.
  • the refrigerator is also provided with a box 5 wherein a drawer 6 that can be inserted or extracted.
  • a vacuum valve 13 normally consisting of a regulated pressure valve or similar well known in the art, whose function and structure are not further explained, whereas the operation of this valve 13 will be described in detail hereinafter.
  • the box 5 is maintained in known manner at a specified temperature, being substantially lodged into said refrigerated compartment 2 or being in some way externally lapped by a flow of cold air. Said box 5 can be opened directly from the outside, and it can be accessible without opening the compartment closure door 4, as exemplified in Figure 2 ; as an alternative to this "drawer-type" embodiment, the whole box 5 may be fully contained in the compartment 2, so that if the user wants to open it, he has to first open the external door 4b and then he can act on a box closing wall 10 ( Fig. 1 ) of the drawer 6.
  • the front closing wall 10 protrudes from the general contour of the drawer 6, and the dimensions and arrangement of the box 5, the drawer 6 and the front closing wall 10 thereof relative to each other are so selected as to ensure that said drawer is capable of being fully inserted in said box up to the point at which the back surface 12 of said front closing wall 10 comes into abutting against the peripheral edge 11 of said box 5 ( Fig. 5-8 ), thereby closing the latter in a vacuum-tight manner.
  • the actual vacuum-tightness can be ensured by arranging appropriate sealing means 14 either against and along the peripheral edge 11 of the box 5 or, alternatively, in the most appropriate position according to the most fitting pattern of the back surface 12 of the front closing wall 10.
  • said front closing wall 10 is provided with a pivotally turning handle 15 which is hinged on two corresponding hinging pins 16 arranged on the two opposite, vertical sides of said front closing wall 10.
  • this handle 15 is made capable of performing a raising and lowering movement about the horizontal axis passing through said two pins 16, as illustrated symbolically in Figures 3 and 4 .
  • the handle 15 is further provided, at its inner ends, with two respective extension links 17 ( Fig. 5-8 ), which are curved in such manner as described in greater detail below.
  • two engagement means which are represented by two projections 18 in the example being considered.
  • the shapes, dimensions and arrangement of the above noted elements relative to each other are so selected as to ensure that, upon the drawer 6 having been pushed into its closed position, wherein it is preferably pushed with the use of said handle 15 on the front side thereof, by subsequently turning the same handle 15 downwards said extension links 17 are caused to engage the respective projections 18 in such a manner as to retain said front wall 10 in the closing position thereof (see Figures 6 and 8 ).
  • Said extensions 17 will of course engage the corresponding members 18 by establishing a kind of semi-elastic, loosable link, so that it will be possible for this link to be released for pulling out and opening the drawer by simply lifting said handle 15, i.e. turning it upwards, so as to release said extension links 17 from the respective projections 18.
  • the need for such a special control device to be used gives rise to a couple of major drawbacks: the first one of these drawbacks is represented by the same air release device, which may in fact be subject to deterioration and, as a result, may eventually constitute an undesired route for the air to pass through, while the second one of said drawbacks certainly lies in the fact that, before the drawer can be pulled out and opened, the need arises for said additional manipulation to be performed in view of operating said air release control device.
  • an improved embodiment of the present invention provides for said vacuum valve 13 to be so arranged as to be capable of being acted upon in such a manner that, as soon as the drawer 6 starts to be opened, and therefore as soon as the handle 15 is lifted, the resulting rotary movement of said extension links 17 causes the latter to act on an electric switch 19, which is preferably located on the outside of said box 5 in a position close to the respective projections 18.
  • Said electric switch 19 is connected via an appropriate link-up 20 to said vacuum valve 13, in such a manner that, as soon as said handle is operated, the release movement of the members 17 and 18 to disengage from each other is preceded by the actuation of said switch 19.
  • This causes said vacuum valve 13 to open, so as to almost instantly restore the internal pressure of the drawer to the ambient value. In this way, the continued turning movement of the handle eventually enables the drawer to be released from its box 5.
  • the switch 19 is also connected to said vacuum pump 7 via appropriate electrical connections (of any known kind and not shown). Upon the drawer having been so released from the box, it can then be pulled out by simply pulling it with the help of the handle 15.
  • Closing the drawer and re-establishing a vacuum inside it are on the contrary performed as follows: the drawer is inserted all the way into its box 5 and, immediately thereafter, the handle 15 is turned down, thereby achieving the following results:
  • control means 30 ( Figure 2 ) may be advantageously integrated with more general control and regulation means that are already present in the refrigeration apparatus.
  • said regulated pressure valve 13 may be most easily implemented with the use of a simple three-way valve of a kind that is well known as such in the art.
  • a refrigerating apparatus as described allows further advantageous improvements; in the facts even if the positive effect on food storage under vacuum condition is well known, yet the vacuum devices are not usually available in the domestic environment; so the food producers directly provide their food products properly packaged under vacuum conditions.
  • These kind of packaging consist of hermetic soft bags, mainly made of plastic sheets, from which air is withdrawn and soon after they are sealed and closed.
  • the embodiment of the present invention offers the possibility of arranging vacuum bag packages directly at home.This improvement is obtained as follows:
  • a dispenser 41 is pivotally mounted on the external wall 40 of the refrigerating apparatus according to the instant invention; said dispenser 41 consists of a prolonged member, internally provided with an hollow duct 42, opened at the outside with a mouth 43, and opened towards said wall 40 with a mouth 44 ( Figures 9 and 10 ).
  • said dispenser is provided with a hinge element that connects said dispenser with said external wall 40 in a rotating way.
  • a second duct 46 connected to a part of said apparatus that is normally kept under vacuum condition; this part may be, e.g. the same box 5 or a stretch of said duct 8 connected to said vacuum pump 7, or even to a buffer tank 25 that will be better described hereunder.
  • said second duct 46 is apt to intake the outside air from its external mouth 47, that, on the outside, is associated to a gasket 49.
  • the described elements are sized and reciprocally arranged so that:
  • the air contained in said bag is at once sucked into said first conduit 42 and second conduit 46, from which it is evacuated away in the remaining portion of said conduit 46, till the vacuum condition in the bag is achieved.
  • the operation continues by hermetically closing the bag opening in a position where the dispenser is not involved, by pushing down the dispenser, and finally by taking away the bag.
  • Such a dispenser may for instance comprise a mouthpiece which could be operated in a vertical direction in parallel with the direction of the airflow creating the vacuum.
  • the mouthpiece is preferably spring loaded to keep the mouthpiece in a normally closing position. Moving the mouthpiece vertically will open the mouth 47 in order for air to flow.
  • said alternative dispenser could both replace the dispenser illustrated in fig. 10 and 11 and also the container for collecting liquid described below in order to create a more user-friendly solution. The gravity will also in this solution create the liquid-air separation.
  • a trap for liquid is provided, that is basically formed by:
  • said trap is able to collect the liquids incidentally entering through said portion 46a, as they would fall by gravity on the bottom of said container 51, so preventing them from entering into the second conduit 46b and from it to the vacuum pump 7 and even to the box 5.
  • said container is provided with means, not shown, that, when needed, can permit to open the same container and to evacuate the liquids possibly there stagnating.
  • a ball valve 55 is provided close to the opening 53. Said valve is arranged in such a way that, when the liquid level 54 approaches the level of said second opening 53, the ball valve 55 will float and rise until it will close said opening 53, so achieving the requested safety.
  • a drawback that can be experienced during the working of a refrigeration apparatus as described refers to the evacuation rate of the box 5 and especially to the air suction in the bag as previously described; said drawback is due to the fact that the vacuum pump has to be necessarily sized in the volume and in the produced noise, and so its suction ability must be limited and as a results this increases the time requested for the vacuum done.
  • a buffer vacuum tank 25 i.e. an hermetic chamber that is inserted in the pipe connecting the vacuum box 5 to the vacuum pump 7.
  • a control valve 28 is positioned between the vacuum box 5 and the buffer vacuum tank 25, while said vacuum valve 13 is arranged between the buffer vacuum tank 25 and the vacuum pump 7.
  • valves 13 and 28 are connected and controlled by said control means mentioned before ( Figure 2 ), so accomplished and connected in order to permit their functioning according to the following procedure:
