Definitions
- the present invention relates to a refrigerating appliance according to the preamble of the first claim, and typically applies to household refrigerators used for preserving and/or storing foodstuffs.
- refrigerating appliances comprise at least one internal compartment adapted to contain foodstuffs and to be cooled by means of a refrigerating circuit.
- Said internal compartment may be a refrigerated one, i.e. kept at an average temperature between 0°C and 10°C, suitable for preserving fresh foodstuffs.
- Household refrigerating appliances which comprise a refrigerator compartment and a freezer compartment, the latter being arranged on top of the refrigerator compartment: such refrigerating appliances are commonly called “double-door refrigerators" by those skilled in the art of household refrigeration.
- refrigerating appliances are also known wherein heat is subtracted from the foodstuffs by forced convection, i.e. by providing cold air circulation inside the refrigerator compartment: these refrigerating appliances therefore stand out from static-type refrigerating appliances (i.e. without forced convection) and are commonly called "no-frost refrigerators" by those skilled in the art.
- the above-mentioned known refrigerating appliances suffer from the drawback that their refrigerator compartment cannot contain hot items such as food cooked in containers (plates, heat-resistant pans, etc.) having a temperature significantly higher than room temperature.
- Patent application EP1564514 describes a household refrigerating appliance comprising a variable-speed compressor driven by the electronic control system based on the temperature detected by sensors located inside the refrigerator compartment. When the sensors detect a considerable rise of temperature caused by hot food placed in the refrigerator compartment, the electronic control system will switch the compressor to maximum power.
- Patent application JP2003-014354 describes a container made of insulating material and suitable for containing hot food just cooked. The food is first placed in the container (having a lid also made of insulating material), which in turn is placed in a household refrigerating appliance. According to JP2003-014354 , the insulating material used for manufacturing the container prevents the hot food from altering the preservation conditions of other foodstuffs.
- the invention aims at providing an appliance wherein the presence of hot items in the refrigerator compartment will not cause any alterations in the preservation conditions of other foodstuffs stored in the same appliance.
- the present invention is based on the general idea of providing a refrigerating appliance in which a refrigerated compartment includes a thermally insulated cell, the inside of which is preferably cooled: thus it will be possible to store hot foodstuffs, or any foodstuffs having a temperature much higher than room temperature, in the cell, without the heat of said foodstuffs radiaring in the refrigerated compartment.
- Such an appliance eliminates any incompatibility issues between the preservation conditions of the foodstuffs stored in the refrigerated compartment and the applicable standards.
- the cell is defined by a separating septum which separates it from the rest of the refrigerator compartment.
- Fig. 1 shows a refrigerator-freezer 1, i.e. a household refrigerating appliance comprising at least two inner compartments 2 and 3 having different temperatures, so that at least two different foodstuffs preservation states are allowed.
- a refrigerator-freezer i.e. a household refrigerating appliance comprising at least two inner compartments 2 and 3 having different temperatures, so that at least two different foodstuffs preservation states are allowed.
- compartment 2 is a refrigerator compartment, i.e. it is suitable for preserving fresh foodstaffs at a temperature between 0 °C and 10 °C, whereas freezer compartment 3 is suitable for preserving frozen foodstuffs; the freezer compartment is located on top of refrigerator compartment 2, in accordance with the typical configuration of double-door refrigerators.
- Both compartments 2 and 3 are closed by respective doors: in particular, door 20 closes refrigerator compartment 2, while door 30 closes freezer compartment 3.
- FIG. 1 shows some items which are commonly found inside a refrigerator compartment, such as shelves 4, 5 and 6 arranged at different heights, but for simplicity's sake it does not show other typical items contained in a refrigerator compartment, such as the lower drawer for vegetables or the lighting device of refrigerator compartment 2, which may advantageously be turned on in accordance with the method described in patent application WO2006/095217 .
- Fig. 1 does not show any additional devices which may be housed in refrigerator compartment 2 of refrigerator-freezer 1, such as an air purification device in refrigerator compartment 2, or a special container adapted to preserve vacuum-packed foodstuffs.
- Double-door refrigerator-freezer 1 shown in Fig. 1 is a no-frost type refrigerating appliance, i.e. the heat is removed by forced convection through circulation of cold air in refrigerator compartment 2 and in freezer compartment 3.
- the cooling power is generated by compressor 10, which is a part of a refrigerating circuit that also comprises evaporator coil 11 (the other components of the refrigerating circuit are not shown in Fig. 1 , since they are well known to those skilled in the art of household refrigeration; for the same reason, the drawing does not show the defrosting device commonly associated with evaporator coil 11), which is located in the rear of freezer compartment 3.
- the air cooled by evaporator coil 11 is circulated by fan 12, when the latter is driven by motor 15, and is partly released in freezer compartment 3 and partly conveyed to refrigerator compartment 2 through supply duct 83, obtained in separating wall 18 between refrigerator compartment 2 and freezer compartment 3.
- Supply duct 83 is connected to distribution means 90 for distributing cold air into refrigerator compartment 2, which comprise venting means 91, 92, 93 and 94 located at different heights in refrigerator compartment 2 (in this example, distribution means 90 consist of a conduit, while venting means 91, 92, 93 and 94 consist of a series of cold air outlets or apertures).
- a gate valve 80 is connected between supply duct 83 and distribution means 90; said gate valve 80, which is traditionally present in double-door refrigerating appliances and is known in the art of household refrigeration as "damper", adjusts the flow rate of the cold air supplied to refrigerator compartment 2 according to the temperature sensed therein.
- the cold air is warmed by the heat subtracted by forced convection from the foodstuffs contained in refrigerator compartment 2 and then returns to the evaporating pack 11 through return section 81 and intake duct 82, obtained in separating wall 18 between refrigerator compartment 2 and freezer compartment 3.
- Refrigerating appliance 1 comprises a cell 9 for cooling hot foodstuffs, the inner temperature of which is lower than that in refrigerator compartment 2; cell 9 is located in the upper portion of the latter and is separated from the rest of the refrigerator compartment by a thermoinsulating separating septum 7 which makes it suitable for storing hot foods.
- Separating septum 7 comprises a layer made from plastic material, preferably polystyrene or polyurethane, which works as a thermoinsulating layer since, as known, this kind of material is a good insulator against heat transfer by conduction.
- the thickness of the plastic layer is preferably between 10 mm and 20 mm, more preferably about 15 mm: in fact, a plastic layer this thick can provide an effective insulating action even in the presence of temperature differences between cell 9 and the remaining volume of refrigerator compartment 2 of about 100°C (though not less effective, thicker layers would be bulkier and would imply a greater reduction in the capacity of the refrigerator compartment 2).
- separating septum 7 may be an insulating panel having at least one inner layer in a vacuum.
- the top surface of separating septum 7 may be coated with a protective coating 77 made from a material capable of withstanding temperatures much higher than room temperature.
- Said protective coating 77 allows the user to place hot food into cell 9 still in the container used for cooking (e.g. if the hot food is a soup, the cooking container may be a metal pot with a lid), without having first to transfer the hot food from the cooking container to another suitable container, such as a Pirex ® glass container.
- the material used for protective coating 77 is preferably heat-resistant rubber capable of withstanding temperatures much higher than room temperature.
- refrigerating appliance 1 is of the no-frost type and comprises distribution means 90 for distributing cold air in refrigerator compartment 2, there will be cold air venting means 91 in cell 9.
- distribution means 90 for distributing cold air in refrigerator compartment 2
- cold air venting means 91 in cell 9.
- Cell 9 is closed by an element 8, i.e. a panel as described below, which also defines the capacity thereof; said capacity is preferably about 15 litres.
- Closing element 8 prevents the air that has become significantly warmer in cell 9 after having exchanged heat with the hot foodstuffs from diffusing in refrigerator compartment 2, in which case it would change the preservation conditions of the foodstuffs stored therein, so that refrigerating appliance 1 would no longer be compliant with the standards specifying food preservation temperatures.
- closing element 8 is also used for allowing the user of refrigerating appliance 1 to gain access to cell 9 in order to store or remove foodstuffs; to this end, element 8 is movable and/or removable, so that the user can open cell 9 through it.
- the separating septum 7 is a removable component.
- closing element 8 is a panel associated with separating septum 7, thus forming a drawer: in this manner, the inside of cell 9 becomes easily accessible by pulling out said drawer either partially or totally with respect to refrigerator compartment 2.
- Fig. 1 shows the positioning of hot foodstuffs and of a number of standard preservation packs in a refrigerator prototype according to the present invention derived from the Ariston MTM 1911 F double-door no-frost refrigerating appliance. It should be reminded that a standard preservation pack is a test element having a parallelepiped shape, made from a material having physical characteristics almost identical to those of beef, in the geometrical centre of which there is a thermocouple for detecting the inner temperature of the pack.
- a hot food P in particular consisting of 3 litres of soup.
- the hot food P is contained in a heat-resistant Pirex ® glass pan with a lid, resting on the separating septum 7.
- the temperature of hot food P is monitored through a suitable temperature probe.
- a number of standard preservation packs have been placed in refrigerating appliance 1 in order to verify the compliance with the requirements of the ISO 15502 preservation standard even in the presence of hot food P.
- said preservation packs are:
- Fig. 2 is a diagram which includes a number of curves showing the progress of temperature TP of hot food P, temperature TS of first preservation pack S, temperature TK of second preservation pack K, temperature TW of third preservation pack W, and temperature TF of fourth preservation pack F as a function of time H.
- the temperature of the standard preservation packs placed in refrigerator compartment 2 turns out to be constantly complying with the ISO 15502 preservation standard as hot food P is being cooled. In fact, at no time their temperature rises above 10°C, the maximum value of temperature TS of preservation pack S being 9°C, the maximum value of temperature TK of preservation pack K being 7.8°C, and the maximum value of temperature TW of preservation pack W being 4.9°C. Nor is freezer compartment 3 affected by the thermal load placed in cell 9 to such an extent as to exceed the parameters of the ISO 15502 standard.
- temperature TF of preservation pack F located in the least cold area of freezer compartment 3, reaches a maximum temperature of-16°C, while said standard requires the average operating temperature in freezer compartment 3 to be approximately -18°C and the temperature reached during transient periods (for instance due to door 30 being opened or to evaporator coil 11 being defrosted) not to exceed -15°C (transient periods may last up to 6h).
- refrigerating appliance 1 is controlled electronically and comprises electronic control means operationally connected to refrigerating power generation means (represented by compressor 10 in Fig. 1 ).
- Electronically controlled refrigerating appliance 1 also comprises sensor means and user interface means, both of which are operationally connected to the electronic control means.
- sensor means refers to one or more devices (temperature probes, humidity probes, etc.) suitable for detecting the value of at least one physical quantity pertaining to the operation of refrigerating appliance 1
- interface means refers to one or more devices (push-buttons, knobs, LEDs, displays, etc.) suitable for allowing the user to set a parameter related to the operation of refrigerating appliance 1 and/or for displaying at least one piece of information pertaining to the operation of refrigerating appliance 1.
- At least two different modes of operation of refrigerating appliance 1 are possible:
- the switching from the first to the second mode of operation may take place as follows:
- the present invention offers several advantages.
- the user of refrigerating appliance 1 can put foodstuffs into refrigerator compartment 2 as soon as it is done, without having to wait for it to cool down to room temperature.
- This anticipated action (which does not jeopardize the compliance with the parameters defined by the ISO 15502 standard, nor does it change the preservation conditions of the other foodstuffs contained in refrigerator compartment 2) eliminates the risk that the user forgets to put the food into refrigerator compartment 2 once it has cooled down to room temperature, in which case the food would remain too long outside refrigerating appliance 1, where it would be much more subject to bacteria and other pathogenic and/or deteriorating agents.
- refrigerating appliance 1 allows the user to cook large quantities of foodstuffs, such as soups or other foodstuffs having similar consistency, to be eaten within a span of a few days, since cell 9 has a large capacity and ensures optimal preservation conditions.
- refrigerating appliance 1 requires neither any critical electronic control nor features such as a variable-speed compressor, which would inevitably imply higher production costs.
- refrigerating appliance 1 allows the user to avoid using specific containers for storing hot foodstuffs in refrigerating appliance 1, said containers generally suffering from the drawbacks of not being suitable for containing all kinds of foodstuffs, of having a rather limited capacity, and of taking up much space inside refrigerating appliance 1.
- front closing element 8 may be complemented by side walls arranged along the edge of separating septum 7, thus forming a drawer.
- cell 9 would be defined by the drawer thus formed, the side walls of which shall preferably be thermally insulated through layers of polystyrene, polyurethane or the like, just like separating septum 7.
