Definitions

  • the present invention generally relates to a refrigerating apparatus, both for domestic and professional use. More particularly, the present invention relates to a refrigerating apparatus having an improved circulation of refrigerating air.
  • a conventional refrigerating apparatus comprises one or more refrigerating compartments, which allow storing and preserving food by refrigeration.
  • Refrigerating air circulation is of the utmost importance for good food preservation, and is particularly burdensome to design in refrigerating apparatuses integrating refrigerating compartments intended to be at reciprocally different temperatures (or combined refrigerating apparatuses).
  • a combined refrigerating apparatus integrating two refrigerating compartments (e.g., a lower-temperature refrigerating compartment and a higher-temperature refrigerating compartment)
  • most of the known solutions are substantially based on the common approach of continuously circulating refrigerating air between both the refrigerating compartments.
  • cold refrigerating air from a heat pump evaporator is first fed to the lower-temperature refrigerating compartment, where it warms up by thermal exchange with food, and then to the higher-temperature refrigerating compartment. Thereafter, the relatively warm refrigerating air from the higher-temperature refrigerating compartment is returned to the evaporator for a new cycle.
  • EP0793066 discloses an appliance comprising a lower-temperature refrigerating compartment and a higher-temperature refrigerating compartment separated from each other by a horizontal partition wall.
  • the refrigerating air from an evaporator is circulated through the lower-temperature refrigerating compartment, and reaches the higher-temperature refrigerating compartment via a gap between a front edge of the partition wall and an appliance door.
  • GB867292 discloses an appliance comprising a refrigerating compartment, and a fan, arranged at an upper rear thereof, for forcing air downwardly over an evaporator within a rear flue. Part of the refrigerating air from the evaporator flows to a lower part of the refrigerating compartment, and the remainder is diverted by a baffle into a hollow shelf, from which it is discharged, through front apertures, into the refrigerating compartment at the appliance door. Scoops divert some of the refrigerating air flowing within the shelf into a suspended container.
  • the temperature of the refrigerating air flowing into the higher-temperature refrigerating compartment from the lower-temperature refrigerating compartment strongly depends on amount of food stored therein, as well as on user operations (e.g ., appliance doors opening for accessing the refrigerating compartments, which causes heat input). This results in food preservation issues, as well as energy issues (as an uncontrollable number of cycles for restoring the desired temperature within the refrigerating compartments is needed).
  • the refrigerating air from the evaporator upon being fed to the lower-temperature compartment, is split into different flows, each one directly reaching (through the gap in the horizontal partition wall) the higher-temperature refrigerating compartment at different times and with different temperature (as resulting from different thermal exchange experienced by each flow along the corresponding path).
  • the higher-temperature refrigerating compartment is affected by a non-uniform, and non-ideal, temperature within it.
  • the Applicant has tackled the problem of devising an improved solution able to overcome the above-discussed, as well as other, drawbacks.
  • the present invention thus relates to a refrigerating apparatus comprising a cabinet, first and second refrigerating compartments for food storage separate from each other, a first air channel between the cabinet and a first refrigerating compartment wall, and a second air channel between the cabinet and a second refrigerating compartment wall, wherein the first and second air channels are configured for canalizing refrigerating air into the first and second refrigerating compartments, respectively, and wherein the first refrigerating compartment opens out to the second air channel for allowing the refrigerating air within the first refrigerating compartment to flow into the second refrigerating compartment through the second air channel, and the second refrigerating compartment opens out to the first air channel for allowing the refrigerating air within the second refrigerating compartment to flow into the first refrigerating compartment through the first air channel.
  • the refrigerating apparatus comprises a liner delimiting the first and second refrigerating compartments, the liner having a rear wall comprising said first and second refrigerating compartment walls and being spaced apart from a rear panel of the cabinet so as to define a rear air channel comprising said first and second air channels.
  • the liner may comprise, at opposite sides thereof, first and second protruding edges laterally delimiting said rear air channel.
  • the refrigerating apparatus may further comprise a partition baffle between the rear wall and the rear panel for partitioning the rear air channel into the first and second air channels, the partition baffle being shaped such that at least one portion of the first air channel extends between the second refrigerating compartment wall and the cabinet and at least one portion of the second air channel extends between the first refrigerating compartment wall and the cabinet.
  • the partition baffle is preferably made of a single piece with the liner.
  • the partition baffle comprises a U-shaped central portion, and, at the ends thereof, first and second appendices extending towards the first and second protruding edges, respectively.
  • said at least one portion of the first air channel comprises a first portion delimited from below by the U-shaped central portion
  • said at least one portion of the second air channel comprises a second portion delimited by the U-shaped central portion, the first appendix, and the first protruding edge, and a further second portion delimited by the U-shaped central portion, the second appendix, and the second protruding edge.
  • the refrigerating apparatus further comprises, at said at least one portion of the first air channel, first liner openings for fluidly connecting the second refrigerating compartment to the first air channel, and at said at least one portion of the second air channel, second liner openings for fluidly connecting the first refrigerating compartment to the second air channel.
  • the second liner openings may comprise first and second openings in the second portion and in the further second portion, respectively, of said at least one portion of the second air channel.
  • the refrigerating apparatus may further comprise a separator extending substantially horizontally between the rear wall of the liner and the cabinet front for separating the first refrigerating compartment from the second refrigerating compartment, the separator defining at least one air passage fluidly connecting the second refrigerating compartment to the first liner opening to allow air flow from the second refrigerating compartment into the first air channel through the at least one air passage and the first liner opening.
  • the separator may comprise a separator top that defines a bottom of the first refrigerating compartment and a separator bottom that defines a top of the second refrigerating compartment, the separator top and the separator bottom being so shaped as to define between them the at least one air passage.
  • the separator top and the separator bottom are preferably made of materials capable of providing thermal insulation between the first and second refrigerating compartments.
  • the refrigerating apparatus may further comprise, along the rear air channel, at least one heat pump evaporator for properly cooling the refrigerating air down to the intended refrigerating temperature, and a fan for promoting refrigerating air circulation.
  • the at least one evaporator preferably comprises first and second evaporators associated with the first and second refrigerating compartments, respectively.
  • the first evaporator is arranged along the first air channel, and the second evaporator and the fan are arranged along the second air channel.
  • the first and second refrigerating compartments comprise combinations of fridge, freezer or zero-degree compartments.
  • the proposed solution allows achieving ideal temperature within the refrigerating compartments. Indeed, thanks to mechanical separation and thermal insulation between the refrigerating airs in the lower-temperature and higher-temperature refrigerating compartments, the refrigerating air flowing from the higher-temperature refrigerating compartment is channeled to the lower-temperature refrigerating compartment only after having passed a first evaporator, and the refrigerating air flowing from the lower-temperature refrigerating compartment is fed to the higher-temperature refrigerating compartment only upon channeling thereof (which provides a uniform mixing thereof) and, preferably, only after having passed a second evaporator. This results in very good food preservation, as well as energy saving.

  • the refrigerating apparatus 100 comprises a number of well-known electronic, mechanical and/or electro-mechanical components - however, for the sake of description ease and conciseness, only those being relevant for understanding the invention will be introduced and discussed in the following.
  • the refrigerating apparatus 100 is of the combined-type, as integrating a number of refrigerating compartments where food can be stored and preserved by refrigeration at different temperatures.
  • the refrigerating apparatus 100 comprises two refrigerating compartments, namely an upper refrigerating compartment 105 U and a lower refrigerating compartment 105 L .
  • the upper 105 U and lower 105 L refrigerating compartments may comprise combinations of fridge, freezer or zero-degree compartments, which have cooling temperatures over, below or near 0°C, respectively (and typically ranging between 3°C and 7°C, -18°C and -27°C, and 0°C and 3°C, respectively).
  • the upper refrigerating compartment 105 U will be assumed operating at higher temperature (hereinafter, higher-temperature refrigerating compartment) than the lower refrigerating compartment 105 L (hereinafter, lower-temperature refrigerating compartment).
  • Shelves and other structures for supporting and storing food articles may be provided within both upper 105 U and lower 105 L refrigerating compartments (as partly visible in Figures 2 , 3A and 3B ).
  • the refrigerating apparatus 100 comprises a substantially parallepiped-shaped cabinet 110, having a top panel 110 T , a rear panel 110 R , a bottom panel 110 B and side panels (not visible).
  • Upper 115 U and lower 115 L doors are hingedly mounted to a cabinet 110 front to provide selective access to the upper 105 U and lower 105 L refrigerating compartments, respectively.
  • the refrigerating apparatus 100 further comprises a liner 120 having a top wall 120 T , a rear wall 120 R , a bottom wall 120 B .
  • the liner 120 is inwardly spaced apart from the cabinet 110 by means of first 205 1 and second 205 2 protruding edges provided at opposite side ends thereof, on both top and back parts of the apparatus.
  • a gap between the liner 120 and the cabinet 110 itself is thus formed by spacing effect of the first 205 1 and second 205 2 protruding edges.
  • the gap between the liner 120 and the cabinet 110 identifies air channels through which cooling air to and from the upper 105 U and lower 105 L refrigerating compartments is made to flow.
  • a top air channel A CH,T is defined between the top wall 120 T of the liner 120 and the top panel 110 T of the cabinet 110
  • a bottom air channel A CH,B is defined between the bottom wall 120 B of the liner 120 and the bottom panel 110 B of the cabinet 110.
  • the top 120 T and bottom 120 B walls of the liner 120 have lower lengths than the top 110 T and bottom 110 B panels of the cabinet, respectively, which allows refrigerating air flowing through the top A CH,T and bottom A CH , B air channels to be fed into the upper 105 U and lower 105 L compartments, respectively.
  • a rear, substantially straight, air channel A CH,R is instead defined between the rear wall 120 R of the liner 120 and the rear panel 110 R of the cabinet 110.
  • the rear air channel A CH,R comprises, between the cabinet 110 (i.e., the rear panel 110 R thereof) and an upper refrigerating compartment 105 U wall (i.e., an upper part of the rear wall 120 R of the liner 120 associated with, e.g. facing, the upper refrigerating compartment 105 U , hereinafter upper rear wall 120 RU ), a first, e.g.
  • upper, rear air channel A CH,RU for canalizing the refrigerating air into the top air channel A CH,T (and hence into the upper refrigerating compartment 105 U ), and, between the cabinet 110 (i.e., the rear panel 110 R thereof) and a lower refrigerating compartment 105 L wall (i.e., a lower part of the rear wall 120 R of the liner 120 associated with, e.g. facing, the lower refrigerating compartment 105 L , hereinafter lower rear wall 120 RL ) , a second, e.g. lower, rear air channel A CH,RL , separate from the upper rear air channel A CH,RU , for canalizing the refrigerating air into the bottom air channel A CH,B (and hence into the lower refrigerating compartment 105 L ).
  • a second, e.g. lower, rear air channel A CH,RL separate from the upper rear air channel A CH,RU , for canalizing the refrigerating air into the bottom air channel A CH,B (and hence into the
  • one or more heat pump evaporators are provided for properly refrigerating the refrigerating air down to the intended temperatures, and a fan F is provided for promoting refrigerating air circulation.
  • upper E U and lower E L evaporators associated with the upper 105 U and lower 105 L compartments, respectively, are preferably arranged along the upper A CH,RU and lower A CH,RL rear air channels, respectively.
  • the fan F is arranged along the lower rear air channel A CH,RL . Even more preferably (as illustrated) the fan F is arranged above the lower evaporator E L . Provision of the upper evaporator E U , of the lower evaporator E L , and of the fan F, not limiting for the invention, may be achieved by any known housing, mounting and fixing techniques.
  • the upper refrigerating compartment 105 U opens out to (thus, being fluidly connected to) the lower rear air channel A CH,RL for allowing the refrigerating air within the upper refrigerating compartment 105 U to be fed into the lower refrigerating compartment 105 L through the lower rear air channel A CH,RL
  • the lower refrigerating compartment 105 L opens out to (thus, being fluidly connected to) the upper rear air channel A CH,RU for allowing the refrigerating air within the lower refrigerating compartment 105 L to be fed into the upper refrigerating compartment 105 U through the upper rear air channel A CH,RU .
  • separation between the upper A CH,RU and lower A CH,RL rear air channels allows preventing the refrigerating air from the upper refrigerating compartment 105 U (and towards the lower rear air channel A CH,RL ) from mixing with the refrigerating air from the lower refrigerating compartment 105 L (and towards the upper rear air channel A CH,RU ).
  • only one evaporator i.e. the lower evaporator E L (i.e., only the evaporator associated to the lower-temperature refrigerating compartment), is provided.
  • the refrigerating air flowing from the lower refrigerating compartment 105 L would be fed to the upper refrigerating compartment 105 U only upon channeling thereof (through the upper rear air channel A CH,RU and the top channel A CH,T ).
  • Channeling of the refrigerating air instead of feeding it directly into the higher-temperature refrigerating compartment (as for the known solutions), provides air mixing and heat distribution, which results in an almost uniform temperature of the refrigerating air.
  • a partition baffle 210 is preferably provided for partitioning the rear air channel A CH,R into said separate upper A CH,RU and lower A CH,RL rear air channels.
  • the partition baffle 210 is part of the liner 120, preferably made of a single piece with it.

  • Arrangement and shape of the partition baffle 210 are not limiting for the invention, as depending on sizes of the upper 105 U and lower 105 L refrigerating compartments, as well as on other specific design options.
  • the partition baffle 210 is arranged and shaped such that at least one end portion of the upper rear air channel A CH,RU extends between the lower refrigerating compartment 105 L wall (i.e., the lower rear wall 120 RL ) and the cabinet 110 (i.e., the rear panel 110 R part facing the lower rear wall 120 RL ), and at least one end portion of the lower rear air channel A CH,RL extends between the upper refrigerating compartment 105 L wall (i.e., the upper rear wall 120 RU ) and the cabinet 110 (i.e., the rear panel 110 R part facing the upper rear wall 120 RU ) - see Figure 2 , showing the partition baffle 210 substantially astride of the upper 105 U and lower 105 L refrigerating compartments.
  • the partition baffle 210 comprises a substantially U-shaped central portion 210 C , and, at the ends thereof, first 210 1 and second 210 2 appendices extending ( e.g ., slightly inclined) toward the first 205 1 and second 205 2 protruding edges, respectively.
  • the two top end portions of the lower rear air channel A CH,RL are arranged opposite to each other with respect to the bottom end portion of the upper rear air channel A CH,RU , i.e. on the opposite lateral sides of such bottom end portion.
  • the illustrated arrangement and shape of the partition baffle 210 is intended to substantially match suitable air openings of the liner 120 (hereinafter, liner openings).
  • a number of liner openings 215 1 ,215 2 are provided in the rear wall 120 R in correspondence of the top end portions of the lower rear air channel A CH,RL , for fluidly connecting the upper refrigerating compartment 105 L to the lower rear air channel A CH,RL .
  • each top end portion there can be one opening or one group of liner openings.
  • the liner openings 215 1 ,215 2 are in the form of gratings, although this should not be construed limitatively.
  • a number of further liner openings 220 1 ,220 2 are provided, in correspondence of the bottom end portion of the upper rear air channel A CH,RU for fluidly connecting the lower refrigerating compartment 105 L to the upper rear air channel A CH,RU (as discussed herebelow).
  • two openings 220 1 ,220 2 are provided that are horizontally aligned to each other, but the number of such openings can be lower ( i.e. only one opening) or higher, so that also in this case it is possible to refer to a group of openings, where the group can be formed by one or more openings.
  • the refrigerating apparatus 100 further comprises a separator assembly 130 extending substantially horizontally between the rear wall 120 R of the liner 120 (for example, as illustrated, at a central part thereof) and the cabinet 110 front, so as to separate from each other and delimit, together with the liner 120, the upper 105 U and lower 105 L refrigerating compartments.
  • the separator assembly 130 comprises a separator top 130 T , that defines a bottom of the upper refrigerating compartment 105 U , and a separator bottom 130 B , that defines a top of the lower refrigerating compartment 105 L .
  • the representation of Figure 1 is only schematic, whereas in the representation of Figure 3B the separator top 130 T is omitted and only separator bottom 130 B is shown.
  • the separator top 130 T and the separator bottom 130 B are made of materials capable of providing thermal insulation between the upper 105 U and lower 105 L refrigerating compartments.
  • the separator top 130 T and the separator bottom 130 B are superimposed to each other and are so shaped that one or more (e.g., two) air passages 135 1 ,135 2 are defined between them.
  • the air passages 135 1 ,135 2 fluidly connect the lower refrigerating compartment 105 L to the liner openings 220 1 ,220 2 , respectively, so that the refrigerating air from the lower refrigerating compartment 105 L is allowed to flow into the upper rear air channel A CH,RU through the air passages 135 1 ,135 2 and the liner openings 220 1 ,220 2 .
  • the separator bottom 130 B comprises one or more (e.g., two) grooves 305 1 ,305 2 (visible in Figure 3B , showing the separator assembly 130 without the separator top 130 T ).
  • the separator top 130 T is shaped in such a way that, when put on the separator bottom 130 B , the gap between it and the grooves 305 1 ,305 2 defines the corresponding air passages 135 1 ,135 2 .
  • both the separator top 130 T and the separator bottom 130 B preferably have the front side bent downward, so that air from the lower refrigerating compartment 105 L can easily flow in.
  • the front side of the separator top 130 T preferably cooperates with the inner surface of the upper door 115 U (as shown in Figure 1 ) or of the lower door 115 L (in a possible different embodiment not shown) when such door is closed, so as to isolate the lower 105 L and upper 105 U refrigerating compartments from each other.
  • Refrigerating air circulation according to the invention may be summarized as follows.
  • Refrigerating air from the upper evaporator E U is first fed, through the top air channel A CH,T , into the upper refrigerating compartment 105 U , where it absorbs heat from food articles thereby allowing refrigeration thereof. Relatively hot refrigerating air within the upper refrigerating compartment 105 U is then allowed to pass through the liner openings 215 1 ,215 2 , and hence, under fan F action, into the lower rear air channel A CH,RL and the lower evaporator E L housed therein.
  • Refrigerating air from the evaporator E L is then fed, through the bottom air channel A CH,B , into the lower refrigerating compartment 105 L , where, upon absorbing heat from food articles for allowing refrigeration thereof, it is fed back to upper rear air channel A CH,RU (and hence to the upper evaporator E U housed therein) through the air passages 135 1 ,135 2 and the liner openings 220 1 ,220 2 .
  • any component thereof may be separated into several elements, or two or more components may be combined into a single element; in addition, each component may be replicated for supporting the execution of the corresponding operations in parallel.
  • any interaction between different components generally does not need to be continuous (unless otherwise indicated), and it may be both direct and indirect through one or more intermediaries.
