Description


[0001] The present invention has as its subject a refrigeration apparatus for food products, for example refrigerators, freezers, fridge freezers.

[0002] Refrigerators are known comprising a refrigeration compartment intended for containing food products.

[0003] In this connection the use is known of shelves attached to a back-panel of a door which allows access to the refrigeration compartment. Such shelves could be designed for containing food products such as, for example, eggs, diced food etc.

[0004] These shelves could furthermore be closed by a cover. The cover is usually hinged to the shelf and is movable between an open configuration in which it allows access to the contents of the shelf and a closed configuration in which it simply rests on the shelf.

[0005] In this context, the technical objective at the base of the present invention is to provide a food refrigeration apparatus which enables an improvement of the existing apparatuses.

[0006] In particular, it is an object of the present invention to make available a refrigeration apparatus for foodstuffs which can be used for keeping perishable products fresh by means of the temperature, while preventing such products (for example medicines) from being accidentally used by an inattentive user.

[0007] The stated technical objective and the specified aims are substantially attained by a food refrigeration apparatus comprising the technical characteristics set forth in one or more of the appended claims.

[0008] Further characteristics and advantages of the present invention will become clearer from the indicative, and therefore non-limiting, description of a preferred but not exclusive embodiment of a food refrigeration apparatus, as illustrated in the accompanying drawings, in which:
  • figures 1 and 2 show perspective views of the refrigeration apparatus according to the present invention;
  • figures 3 and 4 show two perspective views of a component of the refrigeration apparatus of figures 1 and 2.


[0009] In the accompanying drawings, no. 1 indicates a refrigeration apparatus for food products.

[0010] The apparatus 1 comprises:
  • a refrigeration compartment 2 for foodstuffs;
  • a door 3, movable between a closed position and an open position. In the closed position it opportunely obstructs access to said compartment 2 and in the open position it permits access to said compartment 2.


[0011] The door 3 comprises a first shelf 4 for positioning articles. In English technical jargon such a shelf is known as a "door shelf". In the closed position of the door 3 said first shelf 4 faces said compartment 2 and/or it projects inside said compartment 2.

[0012] The door 3 comprises a back-panel 31 to which the first shelf 4 is attached. In technical jargon the term "back-panel" is well-known. Usually the term is intended to mean a panel of the door 3 which in the closed position of the latter faces towards the compartment 2.

[0013] The first shelf 4 comprises a cover 40, movable between a closed configuration and an open configuration. In the open configuration the cover 40 allows access to the articles positioned on the first shelf 4; in the closed configuration the cover 40 prevents access by a user to articles placed on the first shelf 4.

[0014] The apparatus 1 comprises locking means 5 for the cover 40 in said closed configuration.

[0015] The locking means 5 for example comprise a protrusion 9 and a suitable housing 90 for retaining said protrusion 9.

[0016] Opportunely the locking means 5 are of snap type. This for example provides for an elastic deformation of the protrusion 9 during engagement with and disengagement from said retaining housing 90.

[0017] The apparatus 1 comprises unlocking means for said locking means 5. The unlocking means preferably are manually operable. The unlocking means are such as to minimise the risk of undesired unlocking of the cover 40.

[0018] For example the unlocking means could comprise two buttons which must be pressed simultaneously to unlock said locking means.

[0019] In the preferred solution the locking means 5 and the unlocking means coincide. Opportunely the locking means 5 and the unlocking means comprise an ordinary lock.

[0020] The apparatus 1 comprises a housing 41, delimited in combination by:
  • the first shelf 4 with the cover 40 in the closed configuration;
  • a first portion 32 of the back-panel 31. In the open configuration of said cover 40 it is at least partially tilted with respect to its position in the closed configuration and overlaps with at least a part of the first portion 32 of the back-panel 31. In the closed configuration of the cover 40, said first portion 32 of the back-panel 31 advantageously contributes to delimiting said housing 41 at least rearwards and/or upwards and/or laterally. Opportunely the first portion 32 of the back-panel 31 comprises an upper profile and two lateral profiles which project in relief and which contribute, in combination with the shelf 31, to delimiting said housing 41.


[0021] As exemplified in figure 1, the door 3 comprises a plurality of shelves 400 attached to the back-panel 31. The first shelf 4 is the shelf positioned highest compared with the remaining shelves of the back-panel 31. This presents a double advantage. On the one hand it enables a reduction in the possibilities of access to the contents of the first shelf 4 by children; on the other hand it makes it possible to exploit the geometry of the back-panel 31 which contributes to upwards delimiting the housing 41.

[0022] The characteristics of the first shelf 4 could also be applied to another shelf or other shelves attached to the back-panel.

[0023] Opportunely the cover 40 is hinged and can rotate around a first axis 30. In the open configuration the cover 40 is rotated around the first axis 30 with respect to its position in the closed configuration.

[0024] The first shelf 4 opportunely comprises a tray 42. The tray 42 in its turn comprises:
  • a front part 43 which is at least in part surmounted by the cover 40 in the closed configuration (preferably it is completely surmounted);
  • a rear part 44.


[0025] The cover 40 rests on the rear part 44 in a configuration of maximum opening.

[0026] Front and rear are to be understood with reference to a user who with the door 3 open is facing the first shelf 4.

[0027] The cover 40 is advantageously hinged to the tray 42. The cover 40 comprises:
  • a first side 401 which in the closed configuration of the cover 40 is shielded by the front part of the tray 42;
  • a second side 402 which in the closed configuration is shielded by the first portion 32 of the back-panel 31 and which in the maximum opening configuration rests on the rear part 44 of the tray 42.


[0028] The front part 43 of the tray 42 comprises lateral delimitation walls 45.

[0029] The rear part 44 of the tray 42 comprises lateral delimitation walls 46.

[0030] The rear part 44 of the tray 42 comprises lateral delimitation walls 46 which are higher than the lateral delimitation walls 45 of the front part 43 of the tray 42; the first axis 30 of rotation of the cover 40 with respect to the tray 42 is higher than the delimitation walls 46 of the rear part 44; the first axis 30 of rotation of the cover 40 lies in proximity to a transition zone between the front part 43 and the rear part 44. Opportunely the first axis 30 of rotation of the cover 40 is substantially parallel to the first and/or to the second side 401, 402. Advantageously the tray 42 comprises two uprights to which the cover 40 is hinged.

[0031] Opportunely the apparatus 1 comprises an ozoniser and/or an ioniser 7 which emit particles (ozone or ions) having a purifying effect on the contents of the compartment 2 and/or on the air introduced into the compartment 2.

[0032] The active components of the ozoniser and/or of the ioniser 7 are advantageously located in a housing fixed to the ceiling of the compartment 2 (for example to protect them from impacts and so as not to be immediately reachable by a user). These active components are furthermore in fluid communication with the compartment 2 through an opening 92 formed in a wall delimiting said housing. The opening 92 is designed for introducing ozone, ions and air purified by the action of said ozoniser and/or of said ioniser 7 into the compartment.

[0033] The cover 40 comprises at least one hole 91 which in the closed configuration of the cover 40 puts the inside of the first shelf 4 in fluid communication with said compartment 2.

[0034] As exemplified in the accompanying drawings the cover 40 comprises a plurality of through holes 91 which in the closed configuration of the cover 40 put the inside of the first shelf 4 in fluid communication with said compartment 2 (and therefore with the outside of the first shelf 4). The holes 91 are preferably distributed along the cover 40 so as to affect an extended zone of the cover 40. In this connection the smallest area which without discontinuity encompasses all the holes has an area greater than or equal to 30% of a face of the cover 40 which in the closed configuration faces the outside of the first shelf 4.

[0035] Opportunely the smallest area which without discontinuity encompasses all the holes 91 has an area greater than or equal to 30% of a surface of the first shelf 4 designed for bearing articles (i.e. the supporting surface).

[0036] Let a set be defined consisting of every hole 91 which:
  • is formed in the cover 40; and which
  • in the closed configuration of the cover 40 puts the inside of the first shelf 4 in fluid communication with said compartment 2.


[0037] The set may coincide with a single hole or may comprise a plurality of through holes. The area given by the sum of all of the holes forming part of said set is greater than 20% of a face of the cover 40 which in the closed configuration faces towards the outside of the first shelf 4.

[0038] The holes 91 of said plurality of holes are organised along at least three side-by-side rows, each of said rows extending for at least 75% of the maximum width of the cover 40 (the maximum width of the cover 40 is measured along a direction parallel to the first axis 30 of rotation of the cover 40).

[0039] The holes 91 of said plurality of holes preferably face upwards (i.e. face towards the opening 92 designed for introducing particles of ozone, ions and air purified by the action of said ozoniser and/or of said ioniser into the compartment 2). These expedients contribute to ensuring that the ozone and/or the ions with purifying and antibacterial action, coming from the ozoniser and/or the ioniser, can penetrate to the inside of the first shelf 4, but at the same time they enable the contents of the first shelf 4 to be protected from a direct flow of cold air.

[0040] The cover 40 advantageously comprises more than thirty holes 91. The cover 40 is preferably made of an at least partially transparent material. In this way the user can look inside the first shelf without opening the cover 40.

[0041] The invention thus conceived enables multiple advantages to be attained.

[0042] In particular this constructional solution makes it possible to create a housing 41 in which products may be placed which must be kept at temperatures below ambient and which must be protected from accidental access by undesired users. For example a typical application could be the use of the housing 41 as a medicine container in which the products are protected from undesired access by children.

[0043] The invention thus conceived is susceptible of numerous modifications and variants, all falling within the scope of the inventive concept characterising it. Furthermore all the details can be replaced by other technically equivalent elements. In practice, all the materials used, as well as the dimensions, can be any according to requirements.

[0044] Still with reference by way of example to figures 1-4 it is an object of the present invention to make available a foodstuff refrigeration apparatus which can be used for optimising hygiene inside the refrigeration apparatus, at the same time making it possible to protect such products from a direct flow of cold air. In the accompanying drawings, no. 1 indicates a refrigeration apparatus for food products. The refrigeration apparatus 1 advantageously comprises a refrigerator or a fridge freezer.

[0045] The apparatus 1 comprises:
  • a refrigeration compartment 2 for foodstuffs;
  • a door 3, movable between a closed position and an open position. In the closed position it opportunely obstructs access to said compartment 2 and in the open position it permits access to said compartment 2.


[0046] The door 3 comprises a first shelf 4 for positioning articles. In English technical jargon such a shelf is known as a "door shelf". In the closed position of the door 3 said first shelf 4 faces said compartment 2 and/or projects inside said compartment 2.

[0047] The first shelf 4 comprises a cover 40 movable between a closed configuration and an open configuration. In the open configuration the cover 40 allows access to the articles positioned on the first shelf 4. In the closed configuration the cover 40 prevents access by a user to articles placed on the first shelf 4.

[0048] Opportunely the apparatus 1 comprises an ozoniser and/or an ioniser 7 for emitting particles (ozone or ions) having a purifying effect on the contents of the compartment 2 and/or on the air introduced into the compartment 2. The door 3 comprises a back-panel 31 to which the first shelf 4 is attached. In technical jargon the term "back-panel" is well-known. Usually the term is intended to mean a panel of the door 3 which in the closed position of the latter faces towards the compartment 2.

[0049] The active components of the ozoniser and/or of the ioniser 7 (i.e. the purifying particle generators) are advantageously located in a housing fixed to the ceiling of the compartment 2 (for example to protect them from impacts and so as not to be immediately reachable by a user). These active components are in fluid communication with the compartment 2 through an opening 92 formed in a wall delimiting said housing. This opening 92 is designed for introducing ozone, ions and/or air purified by the action of said ozoniser and/or of said ioniser into the compartment.

[0050] Opportunely said ozoniser and/or said ioniser 7 is in fluid communication with an opening 92 formed in the ceiling of the compartment 2 and designed for introducing purifying particles and/or air purified by the action of said ozoniser and/or ioniser 7 into the compartment 2.

[0051] The cover 40 comprises at least one hole 91 which in the closed configuration of the cover 40 puts the inside of the first shelf 4 in fluid communication with said compartment 2 (or in any event with the outside of the first shelf 4).

[0052] As exemplified in the accompanying drawings the cover 40 comprises a plurality of through holes 91 which in the closed configuration of the cover 40 put the inside of the first shelf 4 in fluid communication with said compartment 2 (or at any rate with the outside of the first shelf 4). The holes 91 are preferably distributed along the cover 40 so as to affect an extended zone of the cover 40. In this connection, advantageously the smallest area which without discontinuity encompasses all the holes has an area greater than or equal to 30% of the area of a face of the cover 40 which in the closed configuration faces towards the outside of the first shelf 4.

[0053] Opportunely the smallest area which without discontinuity encompasses all the holes 91 has an area greater than or equal to 30% of a surface of the first shelf 4 designed for bearing articles (i.e. the supporting surface).

[0054] The holes 91 are organised along at least three side-by-side rows, each of said rows extending for at least 75% of the maximum width of the cover 40. The width is measured along a direction parallel to an axis 30 of rotation of the cover 40. As will be better explained below, in the preferred solution, to pass from the open configuration to the closed configuration, the cover 40 rotates around an axis 30 of rotation.

[0055] The holes 91 of said plurality of holes preferably face upwards (i.e. face towards the opening 92 designed for introducing air purified by the action of said ozoniser and/or of said ioniser 7 into the compartment). The above expedients contribute to ensuring that the particles (ozone and/or ions) with purifying and antibacterial action coming from the ozoniser and/or the ioniser can penetrate to the inside of the first shelf 4. At the same time these expedients make it possible to protect the contents of the first shelf 4 from a direct flow of cold air.

[0056] The cover 40 advantageously comprises more than thirty holes 91. The cover 40 is preferably made of an at least partially transparent material. In this way the user can look inside the first shelf without opening the cover 40.

[0057] Let a set be defined consisting of every hole 91 which is formed in the cover 40 and which in the closed configuration of the cover 40 puts the inside of the first shelf 4 into fluid communication with said compartment 2.

[0058] The set may coincide with the first hole 91 or may also comprise said plurality of through holes. The area given by the sum of all of the holes 91 forming part of said set is greater than 20% of a face of the cover 40 which in the closed configuration faces the outside of the first shelf 4.

[0059] Advantageously the apparatus 1 comprises locking means 5 for the cover 40 in said closed configuration.

[0060] The locking means 5 for example comprise a protrusion 9 and an appropriate housing 90 for retaining said protrusion 9.

[0061] Opportunely the locking means 5 are of snap type. This for example provides for an elastic deformation of the protrusion 9 during engagement with and disengagement from said retaining housing 90.

[0062] The apparatus 1 comprises unlocking means for said locking means 5. The unlocking means are manually operable. The unlocking means are such as to minimise the risk of undesired unlocking of the cover 40.

[0063] For example (solution not illustrated) the unlocking means could comprise two buttons which must be pressed simultaneously to unlock said locking means. In the solution shown in the accompanying drawings, unlocking could be performed by overcoming the resistance offered by the locking means (at least a part of which can be elastically deformed to permit closure and opening).

[0064] In the preferred solution the locking means 5 and the unlocking means could even coincide. Opportunely the locking means 5 and the unlocking means comprise an ordinary lock.

[0065] The apparatus 1 comprises a housing 41 delimited in combination:
  • by the first shelf 4 with the cover 40 in the closed configuration;
  • by a first portion 32 of the back-panel 31. In the closed configuration of said cover 40 it is at least partially tilted with respect to its position in the closed configuration and overlaps with at least a part of the first portion 32 of the back-panel 31. In the closed configuration of the cover 40 said first portion 32 of the back-panel 31 advantageously contributes to delimiting said housing 41 at least rearwards and/or upwards and/or laterally. Opportunely the first portion 32 of the back-panel 31 comprises an upper profile and two lateral profiles which project in relief and which contribute, in combination with the first shelf 4, to delimiting said housing 41.


[0066] As exemplified in figure 1 or 2, the door 3 comprises a plurality of shelves 400 attached to the back-panel 31. The first shelf is the shelf positioned highest compared with the remaining shelves of the back-panel. This presents a double advantage. On the one hand it enables a reduction in the possibilities of access to the contents of the first shelf by children; on the other hand it makes it possible to exploit the geometry of the back-panel which contributes to upwards delimiting the housing 41.

[0067] The characteristics of the first shelf 4 could also be applied to another shelf or other shelves attached to the back-panel 31.

[0068] Opportunely the cover 40 is hinged and can rotate around the axis 30 of rotation. In the open configuration the cover 40 is rotated around the axis 30 of rotation with respect to its position in the closed configuration.

[0069] The first shelf 4 opportunely comprises a tray 42. The tray 42 in its turn comprises:
  • a front part 43 which in the closed configuration is at least in part surmounted by the cover 40 (preferably it is completely surmounted);
  • a rear part 44 on which the cover 40 rests in a configuration of maximum opening; said cover 40 being hinged to the tray 42. Front and rear are to be understood with reference to a user who with the door open is facing the first shelf 4.


[0070] The cover 40 comprises:
  • a first side 401 which in the closed configuration of the cover 40 is shielded by the front part of the tray 42;
  • a second side 402 which in the closed configuration of the cover 40 is in proximity to (advantageously shielded by) said first portion 32 of the back-panel 31 and which in the maximum opening configuration of the cover 40 rests on the rear part 44 of the tray 42.


[0071] The front part 43 of the tray 42 comprises lateral delimitation walls 45.

[0072] The rear part 44 of the tray 42 comprises lateral delimitation walls 46.

[0073] The rear part 44 of the tray 42 comprises lateral delimitation walls 46 which are higher than lateral delimitation walls 45 of the front part 43 of the tray 42; the axis of rotation of the cover 40 with respect to the tray 42 is higher than the delimitation walls 46 of the rear part 44; the axis of rotation of the cover 40 lies in proximity to a transition zone between the front part 43 and the rear part 44. Opportunely the axis 30 of rotation of the cover 40 is parallel to the first and/or to the second side 401, 402. Advantageously the tray 42 comprises two uprights to which the cover 40 is hinged. The invention thus conceived enables multiple advantages to be attained.

[0074] In particular this constructional solution allows the particles emitted by the ozoniser/ioniser to also affect products placed inside said first shelf 4, protecting them at least partially from contact with a cold air flow.

[0075] The invention thus conceived is susceptible of numerous modifications and variants, all falling within the scope of the inventive concept characterising it. Furthermore all the details can be replaced by other technically equivalent elements. In practice, all the materials used, as well as the dimensions, can be any according to requirements.
