Definitions

  • the invention relates to a two-door type refrigerating appliance (1) having a cell for fresh food and a cell for frozen food, equipped with energy-saving elements.
  • Combined refrigerating appliances usually are characterized in that they have big freezer compartments, generally having a capacity of more than 70/80 It.
  • the cell for frozen food of these types of refrigerating appliances is located in the lower part of the appliance and is made of plastic material.
  • the cell for frozen food therefore consists of a housing made of plastic material inserted within a chair-shaped carrier structure, which supports the cell for fresh food.
  • the plastic housing used for the cell for frozen food in combined refrigerating appliances is such to allow the insertion of a series of elements, among which: drawers, shelves and an evaporator arrangement.
  • the cell for frozen food is located in the upper part of the appliance and of reduced size : while in “combined” refrigerating appliances the size of the cell for frozen food may even be 40-50% of the volume of the cell for fresh food, in “two-door” refrigerating appliances the volume of the cell for frozen food is in most cases smaller than 30% of the volume of the cell for fresh food; typically said cell for frozen food having a volume of less than 60 It.
  • the smaller size of the cell for frozen food allows it to be made of aluminum. Within the cell for frozen food there are some visible shelves, which may be metal grids or solid shelves made of a plastic or glassy material. As it will become apparent later, the aluminum structure offers the advantage of allowing to provide an evaporator running all around said structure, thus remaining within the walls of the cell for frozen food.
  • the food is cooled in a known way through a cooling system comprising a motor operating a compressor, whose task is to compress a gas, generally R134a or R600a, which then reaches high pressure, and to keep it in the gaseous state and to send it to a condenser, where it condenses and it becomes a high-pressure liquid; thanks to a coil located on the rear of the refrigerating appliance, the liquid dissipates its heat and cools down. Subsequently, the high-pressure refrigerant liquid flows through an expansion unit.
  • the expansion unit is a component fitted between the condenser and the evaporator system of the refrigerating appliance, having the function of causing a sharp pressure drop.
  • the expansion unit therefore acts as a pressure differential.
  • the presence of a pressure differential in a refrigerating cycle is very important, as it causes a variation of the gas boiling point. Without this pressure variation, the refrigerant liquid would not reduce its temperature significantly, reaching some tens of °C below zero, and therefore no refrigeration would take place; the system would just be a simple container of the refrigerant element, e.g. R134a or R600a.
  • the refrigerant exiting the expansion unit is then sent to a coil, called evaporator, which runs within the walls of the refrigerating appliance in order to absorb heat from within the cell which has to be cooled. Having absorbed heat, the refrigerant liquid evaporates and returns to the gaseous state. This allows to obtain the refrigeration process within the refrigerating appliance.
  • the gas is subsequently sent to the compressor and the cycle starts again.
  • the evaporator can be provided in two different and complementary way.
  • the evaporator In "two-door" refrigerating appliances according to the state of the art, the evaporator is made in two parts, one associated with the cell for frozen food and the other associated with the cell for fresh food, and is fitted between the outer part of said refrigerating appliance and the cells; an insulating foam is then injected between the two walls. In particular, the evaporator envelops the cell for frozen food completely.
  • the cooling system comprises an evaporator arrangement: the evaporator, which in "two-door” refrigerators is a coil located outside the cell to be cooled, in “combined” refrigerating appliances is provided through a self-standing tubular structure arranged in the form of shelves within the cell. Solutions of evaporator arrangements are known from Patents GB 2133518 and GB 2133519.
  • Aim of the present invention is to solve the above-mentioned problems related to known refrigerating appliances by providing a refrigerating appliance of the type known as "two-door" which allows to save electrical energy and to obtain excellent performance.
  • a further aim of the present invention is to provide a solution for the above problems of the known art, being said solution both economical and efficient.
  • a two-door type refrigerating appliance (1) comprising:
  • said cell for frozen food comprises a dividing shelf, below which said evaporator section runs.
  • Fig.1 illustrates a "two-door" refrigerating appliance, indicated as a whole with reference 1.
  • Said refrigerating appliance comprises two cells (cell for fresh food (2) and cell for frozen food (3)) which may be accessed independently from each other through respective closing systems (6,7).
  • said closing systems (6,7) e.g. doors, are shown in the open position, so as to show the inside of said cell for fresh food (2) and of said cell for frozen food (3).
  • figure 1 does not show the cooling system of the refrigerating appliance in its entirety.
  • Said system shown in figures 2 and 3, and further described later, comprises the above-described known elements, i.e.: compressor, condenser, expansion unit (in particular, one or more capillary tubes) and one or more evaporators.
  • the "two-door" refrigerating appliance being the object of the invention comprises a cell for frozen food (3), located in the upper part of said refrigerating appliance and having a reduced size; in particular, said size is such as to allow for the insertion of just one dividing shelf (4).
  • the spaces (12,13) defined by said shelf (4) within the cell for frozen food (3) are big enough to allow the placing of food.
  • said spaces are not less than 10 cm high.
  • the cell for frozen food (3) comprises an additional section (5,14) of the evaporator, i.e. that element of the internal cooling system in which the refrigerant liquid flows (e.g. R134a, R600a, freon).
  • element of the internal cooling system in which the refrigerant liquid flows e.g. R134a, R600a, freon.
  • said additional evaporator section (5,14) runs outside the cell for frozen food and exits from at least one of said walls, thus running within the cell for frozen food (3).
  • said refrigerating appliance (1) therefore has an evaporator section, hereafter referred to as "outer evaporator” (14) and indicated in figures 1 and 2 by a broken line, which, as in the prior art, extends around the cell for frozen food (3) and the cell for fresh food (2), as well as another evaporator section, hereafter referred to as “inner evaporator” (5) and indicated in figures 1 and 2 by a continuous line, which runs within said cell for frozen food (3).
  • fig. 2 shows a preferred embodiment of the cooling system of a refrigerating appliance according to the invention: a compressor (15) compresses a refrigerant (e.g. freon or R134a or R600a), being in the gaseous state, into a condenser (16) wherein it condenses and cools down.
  • a refrigerant e.g. freon or R134a or R600a
  • the refrigerant flows through a filter (17) which traps any impurities being present in the circuit, and subsequently flows in a capillary tube (20) before entering the evaporator.
  • the refrigerant flows in an evaporator consisting of a system of pipes, being generally arranged as a coil running mostly within the walls of the refrigerating appliance and then returning to the compressor (15). Along this path from the capillary to the compressor, the refrigerant element in the liquid state absorbs heat and evaporates, thus cooling the inside of the refrigerating appliance.
  • the evaporator according to the invention also exits from a point (18) of a wall of the cell for frozen food (3) and runs within the volume of said cell for frozen food.
  • This exposed section of the evaporator (5) enters again the walls of the refrigerating appliance at a point (19) of said cell for frozen food (3). From that point, the "inner evaporator” (5) becomes “outer evaporator” (14) again and resumes its path, hidden from view, within the walls of the refrigerating appliance (1) as far as the compressor (15).
  • this technical solution allows to produce a refrigerating appliance wherein, for the same volumes, the cooling of the food in the cell for frozen food (3) takes place with a saving of energy: the increase of the refrigerating area, in fact, allows the cooling system to absorb a larger amount of calories from the cell for frozen food, without the need of increasing the operation cycles (i.e. the time periods during which the compressor is on) of the system, and therefore permits to reduce the energy consumption without having to increase the compressor power or to improve the insulating elements.
  • the location of the "inner evaporator" (5) is such to improve the cooling of the cell for frozen food (3), in that a cooling evaporating surface is brought within said cell for frozen food.
  • the refrigerating appliance (1) is a machine that takes heat from a thermal source (the food within a cell) and yields it to another thermal source (the refrigerant element), and from this to the external environment thanks to the work carried out by the machine itself, which therefore draws energy from the electric network.
  • said amount of heat (Q) should be equal to the energy (E) drawn from the electric network, but actually, due to various dispersions, there is just a proportionality between these two physical quantities.
  • said increase of the evaporating area is made possible by the "inner evaporator” (5), i.e. an evaporator section which, besides enveloping entirely the cell for frozen food (3) while remaining between the walls of said refrigerating appliance and the outer walls of the cells for fresh food (2) and/or for frozen food (3), inventively also runs within said cell for frozen food (3).
  • the "inner evaporator” (5) i.e. an evaporator section which, besides enveloping entirely the cell for frozen food (3) while remaining between the walls of said refrigerating appliance and the outer walls of the cells for fresh food (2) and/or for frozen food (3), inventively also runs within said cell for frozen food (3).
  • FIG. 3 shows the cooling circuit, i.e. a circuit diagram of a cooling system, of a second embodiment of a two-door type refrigerating appliance according to the invention.
  • the two-door type refrigerating appliance has two cells, namely a cell for frozen food (3) and a cell for fresh food (2), represented therein through the respective evaporators 31 and 32.
  • the cooling system includes a compressor (15), upstream of which there are, in sequence, a condenser (16), a hot pipe (33), a filter (17) and a three-way solenoid valve (34), which is controlled by an electronic thermostat (40); at this point, the cooling circuit is split into two circuits represented by two capillaries, namely a refrigerator capillary (35) and a freezer capillary (36), being connected to said solenoid valve (34), which can perform the hydraulic switching between said two capillaries (35) and (36), so that they may be supplied alternately by the compressor (15) depending on whether it is necessary to cool the cell for frozen food (3) only, or both the cell for fresh food (2) and the cell for frozen food (3).
  • a compressor upstream of which there are, in sequence, a condenser (16), a hot pipe (33), a filter (17) and a three-way solenoid valve (34), which is controlled by an electronic thermostat (40); at this point, the cooling circuit is split into two circuits represented by two capillaries,
  • Both capillaries (35) and (36) cross a return pipe (39) in a first heat exchanger (37), from which they exit by following separate paths.
  • the refrigerator capillary (35) passes through a second heat exchanger (38) and then conveys the refrigerant fluid circulating within to the upper part of an evaporator (32) of the cell for fresh food (2).
  • the fluid After having run all the evaporator (32) of the cell for fresh food (2), the fluid goes back up and flows through said second heat exchanger (38), thereby absorbing heat from the refrigerator capillary (35), and then enters an evaporator of the cell for frozen food (31).
  • the evaporator coil of the cell for frozen food (31) envelops the whole outside surface (section called “outer evaporator”) of the cell for frozen food (3) and, according to the invention, before terminating into said return pipe (39) and going back to the compressor (15), also runs within (section called “inner evaporator” (5)) said cell for frozen food (3), as described with reference to figure 2.
  • freezer capillary (36) runs directly into the upper part of the evaporator of the cell for frozen food (31), therefore without passing through said second heat exchanger (38).
  • the electronic control system of the refrigerating appliance consists of a first temperature sensor (42), located in the cell for fresh food (2), which provides information about the temperature of the air in the cell for fresh food (2) to an electronic thermostat (40); likewise, a second temperature sensor (43) sends information about the temperature of the air in the cell for frozen food (3) to the same electronic thermostat (40).
  • control logic of said electronic thermostat (40) can, depending on the values read by said temperature sensors (42, 43), decide moment by moment whether to cool both cells (2,3) in cascade or the cell for frozen food (3) only, by sending a suitable signal to the solenoid valve (34), which in turn will switch the refrigerant fluid either in the refrigerator capillary (35) or in the freezer capillary (36).
  • Figure 3 at last also shows a third sensor (41), located on the evaporator (32) of the cell for fresh food (2) and used for controlling the defrosting of said evaporator.
  • a third sensor located on the evaporator (32) of the cell for fresh food (2) and used for controlling the defrosting of said evaporator.
  • the two embodiment examples of two-door type refrigerating appliances according to the invention advantageously allow to save energy due to a larger evaporating area, obtained thanks to the evaporator section extending within the cell for frozen food.
  • said evaporator section running and visible within said cell for frozen food (“inner evaporator” (5)) is provided as a coil whose straight sections have a length almost corresponding to the depth of said cell for frozen food (3), being the coil loops close enough to be used as a bearing surface for food.
  • a solution of this type may therefore be used as a shelf within the cell for frozen food.
  • the evaporator runs around the side walls (9), the upper wall (11) and the lower wall (10) of the cell for frozen food, whereas it comes out from the rear wall (8) (i.e. facing a user who stands in front of said refrigerating appliance (1) and opens the corresponding door (6) of said cell for frozen food (3)).
  • the evaporator After running within the cell for frozen food (3), the evaporator enters again said rear wall (8) to run within the other walls of said cell for frozen food and return, as described, to the compressor.
  • the "inner evaporator" (5) exits from the rear wall (8) or from any other wall (9,10,11). It is nonetheless advantageous that its shape makes it usable as a shelf.
