Description

[0001] Sustainable Refrigeration Door

[0002] OBJECT AND FIELD OF THE INVENTION

[0003] The present invention belongs to the technical field of mechanics, particularly to the field of refrigeration doors, in particular to commercial refrigeration doors that have glass, and more particularly to doors that have elements to support the glass package or insulated glass.

[0004] BACKGROUND OF THE INVENTION

[0005] In the commercial refrigeration sector, doors are one of the most important elements, as they allow access to the refrigerated space and are responsible for maintaining the proper temperature and humidity inside. Commercial refrigeration doors that use insulated glass units are characterized by excellent thermal insulation, which reduces heat loss and maintains the internal temperature of the space.

[0006] A commercial refrigeration door is a structure that allows access to a refrigerated area. They are classified based on their opening, construction material, thermal insulation, and closing system: swing doors, sliding doors, folding doors, and roll-up doors. They can also be classified based on their construction material: commercial refrigeration doors can be classified as: stainless steel doors, aluminum doors, or doors made of combinations of metal and plastic materials.

[0007] Commercial refrigeration doors are essential for maintaining the proper temperature and humidity in refrigerated rooms, which is critical for preserving food and other products.

[0008] Commercial refrigeration doors with insulated glass units offer several advantages, including greater energy efficiency, reduced temperature loss, lower energy consumption, and lower maintenance costs. These advantages make commercial refrigeration doors with insulated glass units a very attractive option for the commercial refrigeration industry.

[0009] In the commercial sector, refrigerated doors with insulated glass are essentially composed of the following elements: - Frame: The frame is the structure that supports the door and holds it in place. It is made of stainless steel, aluminum, or plastic.

[0010] - Door leaves: The door leaves are the moving parts of the door. They are made of insulated glass, which is a type of glass consisting of two or more sheets of glass separated by a space filled with air or gas.

[0011] - Locking system: The locking system is the mechanism that keeps the door closed. It can be manual or automatic.

[0012] Multiple alternatives have been designed for assembling these elements and are available in the prior art. For example, document ES2923577T3, entitled "Door for Mounting a Removable Electronic Display Medium," is a display case door that includes an insulated panel assembly that is transparent to visible light. The door also includes a door frame that extends around a peripheral edge of the insulated panel assembly and is secured thereto, an electronic display superimposed on the insulated panel assembly, and at least one display retainer secured to the door frame and having a coupling end that engages the electronic display to releasably secure the display to the door frame. However, this document does not disclose a door containing a frame profile with an adhesion element and a fastening element for securing a triple insulated glass package.

[0013] Also, document CA1057347, entitled “Insulated Refrigerated Door Frame,” relates to refrigerator cabinets and, more particularly, to a door frame structure for use with such cabinets. In contemporary refrigerated cabinets, heat is absorbed by conduction from the air outside the refrigerator and conducted through the metal door frame around the edge of the door and to the cold portion of the door frame that is in contact with the cold air inside the refrigerator.The present invention overcomes this defect of the prior art by providing a channel-shaped structural member for use as a refrigerator door frame, having a generally U-shaped cross-section including a first flange, a second flange, and an intermediate center portion, wherein the improvement comprises a thermally insulating thermal barrier interposed between said center portion and said second flange, and maintaining said portions in a rigid, spaced-apart relationship. However, this document also does not disclose a door comprising a frame profile with an adhesion element and a fastening element for securing a triple insulated glass package.

[0014] Also, document JP2007504424A, referred to as “Improved Insulation Panel” refers to an insulation panel comprising: a frame member for defining a periphery of the panel; a first wall supported by the frame; and the first wall; a second wall defining an internal space of the panel together with the first wall; and between the first and second walls a panel further comprising at least one intermediate wall disposed in the interior space, wherein the first wall is located in the interior space between the intermediate wall and the first wall. A panel that creates a second space in the intermediate space between the intermediate wall and the second wall, wherein the frame is first, each adjacent surface for receiving and supporting the second and intermediate walls. A panel in which the intermediate wall insulates the first wall from the second wall.However, this document also does not disclose a door containing a frame profile with an adhesion element and a clamping element for fixing a triple insulated glass package, and said invention does not present a lighting conduit.

[0015] Likewise, document CN210688897U, entitled "Refrigerator Door and Heat-Preserving Refrigerator," refers to a utility model describing a heat-preserving refrigerator door, all configured with an aluminum frame incorporated through the inner frame of the door and the door leaf frame to the wooden structure of the refrigerator door with an aluminum package formed. It has an aluminum frame profile incorporated into the door frame, double-sided adhesive tape, insulating material, foam adhesive, and a configuration of four structural seals.However, this document also does not disclose a door containing a frame profile with double-sided tape that is used as an adhesion element for the insulated glass package and does not have a front fastening element to fix a triple insulated glass package and create a system to hold the insulated glass package, and said invention does not have a lighting conduit.

[0016] Finally, document ES2702960T3, entitled "Luminous Glazed Assembly", refers to a luminous glazed assembly comprising: a multiple pane, with main exterior faces called the first exterior face and the second exterior face, comprising a first pane with faces called the internal face and the first face; a second pane with a bonded face and a second face, the bonded face being opposite the internal face, which uses glue to fix the insulated glass package to the profile. However, this document also does not disclose a door containing a frame profile with double-sided tape that is used as an adhesion element for the insulated glass package, together with a front fastening element for fixing a triple insulated glass package to create a system for supporting the insulated glass package; furthermore, said invention does not have a lighting conduit.

[0017] TECHNICAL PROBLEM TO BE SOLVED

[0018] A solution is sought with a frame profile that is easy to hold an insulated glass package, in addition to providing a solution that involves a smaller number of parts, reducing the assembly time and manufacturing cost of a refrigeration door. This invention proposes a frame profile with an adhesive element, such as double-sided tape, used to adhere the insulated glass package on one side and a fastening element on the front to secure and hold the triple insulated glass package on the other side, such that a system is established to support the insulated glass package. In addition, a solution is provided for incorporating a lighting system into the refrigeration frame itself.

[0019] The present invention falls within the technical field of refrigeration systems, specifically focusing on improving the frame profiles that make up refrigeration doors by introducing recycled materials. This innovation aims not only to optimize the structural strength and thermal efficiency of these profiles, but also to promote sustainability through the use of recycled materials.

[0020] Conventional refrigeration doors have traditionally used materials such as stainless steel, aluminum, and engineering plastics. Although these materials are robust, the need to address environmental concerns and move toward sustainable practices has led to a constant search for alternatives, including the use of recycled materials.

[0021] Despite the improvements achieved through the use of recycled materials in some applications, challenges related to energy efficiency and sustainability persist in the design of frame profiles for refrigerated doors. The need is for a comprehensive solution that offers not only improved performance but also a significant reduction in the carbon footprint.

[0022] The present invention proposes a disruptive improvement by introducing high-performance recycled composite materials for the manufacture of refrigeration door frame profiles. This approach not only addresses current challenges in terms of efficiency and durability but also integrates sustainable principles by using recycled materials, thus contributing to waste reduction and promoting environmentally friendly practices.

[0023] The key innovation of the invention lies in the adoption of recycled composite materials for the frame profiles. These materials comprise a matrix reinforced with fibers obtained from recycled sources, such as recycled carbon fiber or fiberglass from industrial waste. The use of a recycled matrix in conjunction with recycled fibers not only provides exceptional structural strength but also actively contributes to waste reduction and the circular economy.

[0024] The introduction of recycled composite materials offers several advantages. These include a significant reduction in the system's carbon footprint by leveraging recycled materials instead of virgin resources, as well as greater design versatility to adapt to diverse cold room needs. Furthermore, sustainability is promoted by closing the life cycle of materials and encouraging environmentally responsible practices in the refrigeration industry.

[0063] DETAILED DESCRIPTION OF THE INVENTION Referring in more detail to the drawings, as shown in Figure 1 through Figure 20, a Sustainable Refrigeration Door (10) is described and it is to be expressly understood that this exemplary embodiment is provided for descriptive purposes only and is not intended to unduly limit the scope of the present inventive concept. Other embodiments and variations of the present invention entitled Sustainable Refrigeration Door (10) are contemplated within the present inventive concept as set forth in the claims herein.

[0064] The Sustainable Refrigeration Door (10) is a system of several elements that are assembled to fix and support the insulated glass package. The Sustainable Refrigeration Door (10) is made up of door profile sections (30) that form the complete frame of 4 sides of the door, a glass package (20) of those commonly used in refrigeration doors with 3 insulated glasses for better thermal efficiency, an adhesive element (40) that keeps one side of the glass package (20) adhered to the door profile section (30), a cover (50) that holds the glass package (20) on the other side and a magnetic seal (70) mounted on the door profile sections (30) to provide the function to the door so that it can magnetically adhere when the refrigerated compartment where the door is installed is closed.

[0065] The Sustainable Refrigeration Door (10) uses four door profile sections (30), one for each side, one for the base and another for the upper part, where the joining means between the door profile sections (30) can be those known in the state of the art, for example with the use of screws.

[0066] The door profile sections (30) are made up of longitudinal profile pieces, each of which has a perimeter wall (33) that is exposed towards the outside of the door frame; likewise, the perimeter wall (33) has two walls, one at each of its ends, projected towards the inside of the frame, at the front end a front wall (31) is projected substantially perpendicularly and at the other end of the perimeter wall (33) a magnetic wall (32) is projected substantially perpendicularly, such that the front wall (31) and the magnetic wall (32) are substantially parallel.

[0067] The length of the front wall (31) and the magnetic wall (32) define the width of the frame of the Sustainable Refrigeration Door (10). The front wall (31) and the magnetic wall (32) are joined by an inner wall (34), which is the surface where the glass package (20) rests on the base, sides and top of the frame.

[0068] The perimeter wall (33) also has a vertical support wall (38) that projects parallel to the magnetic wall (32) through the interior of the profile to the interior wall (34). Likewise, the vertical support wall (38) has a horizontal support wall (39) that projects parallel to the interior wall (34) through the interior of the profile to the front wall (31).

[0069] The vertical support wall (38) and the horizontal support wall (39) are structural elements that give better support and strength to the profile so that the glass package remains firmly in place. In addition, these walls, together with the front wall (31) and the perimeter wall (33), form an interior space in the profile, of a square or rectangular shape to insert elements that give rigidity to the frame or joining elements in the corners of the frame to join the door profile sections (30).

[0070] Each door profile section (30) has a Cover Receiver (36) that has the function of receiving the cover (50) so that it can be assembled. Said cover receiver (36) is arranged at the junction of the perimeter wall (33) and the front wall (31) and is a square or rectangular element with a slot towards the front of the profile. Likewise, each door profile section (30) has a Seal Receiver (37) that has the function of receiving the Magnetic Seal (70). Said seal receiver (37) is a slot in the back of the profile located in the magnetic wall (32).

[0071] On the inner wall (34) an adhesion wall (35) is projected perpendicularly, which provides an outstanding innovation in the Sustainable Refrigeration Door (10), since it has 2 essential functions, first, it provides the surface for the adhesive element (40) to be placed, in such a way that the glass package (20) adheres to the profile, and second, it provides a space to form a lighting channel (320).

[0072] The adhesive element (40) can be a double-sided tape or another element that allows it to be fixed on the adhesion wall (35) and to which the glass package (20) can also adhere.

[0073] Figures 6 and 7 show the placement of the adhesive element (40), then, in figures 8 and 9, the assembly of the glass package (20) on the door profile sections (30) can be seen and how one side of the glass package is adhered to the adhesive element (40), so that when joining the 4 door profile sections (30) of the Sustainable Refrigeration Door (10) the entire glass package (20) is glued and held on the sides.

[0074] Figures 10 and 11 show how the cover (50) is inserted into the Cover Receiver (36) after the glass package (20) has been secured. The cover (50) is a longitudinal element that is inserted into the entire slot of the Cover Receiver (36), where the coupling means is a male type cover connector (51).

[0075] In another embodiment of the Sustainable Refrigeration Door (10), the Cover Receiver (36) may have more than one slot for placing the cover.

[0076] (50); Similarly, the cover (50) may have more than one cover connector

[0077] (51) to be inserted into the slots of the cover receiver (36).

[0078] In figures 15 and 16, the Magnetic Seal (70) is shown, which is a longitudinal element that is inserted into the slot of the Seal Receiver (37) and that has the function of magnetically fixing the door with the refrigeration frame by means of the insertion of the seal connector (71).

[0079] In another embodiment of the Sustainable Refrigeration Door (10), the Seal Receiver (37) may have more than one slot for the placement of the Magnetic Seal (70) to adapt to the magnetic seals (70) known in the state of the art, which may have more than one seal connector (71).

[0080] The lighting channel is a space formed by the adhesion wall (35), the interior wall (34) and the projection of the magnetic wall (32), which projects beyond the interior wall (34).

[0081] In a preferred embodiment, the Sustainable Refrigeration Door (10) has a handle (60) preferably on a side, i.e. on a side section of the door profile (30). The fixing of the handle (60) on the side section of the door profile (30) can be done with known fixing elements and means, for example, with the use of screws or rivets.
