- the present invention relates to a home composting system for compost production starting from biodegradable organic substances.
- the present invention relates to a cooker hood configured both for cooking fumes suction and for organic waste decomposition. Summary of the invention
- the present invention relates to an organic waste home composting system integrated in a cooker hood, which uses the heat of cooking fumes to speed up the decomposition process of the waste contained in a dedicated chamber, so that optimal temperature, humidity and ventilation conditions are provided and maintained therein and the waste decomposition and compost ripening occurs correctly.
- Wastes are positioned inside a chamber provided in the hood central body and they are subjected to a forced thermo-ventilation when, while traditionally functioning, the hood sucks cooking fumes from suitable openings provided therefor, and, before being discharged outside the room where the hood is arranged, the air is conveyed inside the chamber containing the waste, thus speeding up the compost production .
- Waste home composting systems are known at the state of the art and commonly used.
- An example is described in Patent application CN1858027A relating to a method for transforming cooking waste in fertilizer, with the following steps: waste immersion in water, elimination of salt, sugar, water and oil, separation of not degradable organic substance and crushing at 2 cm dimension .
- Patent US9499963B2 relating to a device for waste treatment, which can be arranged under the sink, which comprises a separator extracting liquid from organic waste and conveying it directly to the sewer.
- the remaining solid, in form of organic pulp is dried in a drier and put in a removable container.
- WO1992020451 Another example is described in WO1992020451, in which it is shown a kitchen composter which consists in a chamber floor-mounted and connected to a waste disposer for water elimination and collection of triturated food waste, suitable to produce compost for garden.
- WO1992020451 need, to be installed, expensive and complex structural and plant interventions of the apartment .
- composting systems even the smallest or mini ones, are to be used in middle and large dimensions outdoor spaces, and they are not configured to allow their use in an inhabited place.
- Another technical problem is the energetic consumption needed for the composter functioning and in particular for creating the heat needed for the decomposition process.
- the device according to the present invention uses the heat present in cooking fumes to speed up the organic waste decomposition process.
- the consumptions are low since active cycle consumption is of only 150W, while in case of inactive cycle it is not over 2W.
- the present invention provides a cooker hood which is also a kitchen composter, able to compost organic waste by exploiting the heat derived from the cooktop.
- the present invention provides a composting system configured to function also with no heat deriving from the cooktop, by providing heat by means of an inner resistance, and by activating automatic thermo-ventilation cycles.
- the present invention provides a composting system which eliminates the problem of bad odours linked to the compost production .
- the present invention provides an adjustable hood, which by means of a slider can be height-adjusted according to needs.
- another aim of the present invention is to provide a device indicating to the user the end of the composting process by light signaling means.
- the hood can be provided with a sensor which activates suction and waste composting automatically when the heat coming from the cooktop is detected.
- the device is also particularly apt to be used frequently, for constant recycling of small quantities of wastes.
- the present invention reaches the prefixed aims since it is a cooker hood for cooking fumes with integrated waste composting chamber, comprising: a hollow cylindrical body (1) comprising a first base (11) through which the inner volume of said cylindrical body communicates with a suction duct, and a second open base (7); a plurality of internally hollow appendixes, provided with downwards-directed openings (4) and whose inner recess communicates with the inner volume of said cylindrical body (1); at least a fume extraction means, and characterized in that it comprises further an extractable container (8), configured to be filled with organic wastes and to be introduced inside said central cylindrical body (1) through said second base (7) and to seal, when introduced, said opening (7) of the central body, said hood being configured to suck air through said downwards-directed openings (4), to make it pass inside said extractable container (8), and after, to expel it outside.
- Figure 1 shows a prospective view of the device according to the invention, highlighting the main elements thereof.
- Figure 2 show a front view of the invention during its functioning.
- Figure 3 shows a bottom view of the invention.
- Figure 4 shows the invention utility in creating organic compost useful to nourish plants.
- the hood according to the invention comprises a central cylindrical body (1), hollow inside, and configured to be arranged horizontally on a cooktop (6).
- the cylindrical body comprises a first base (11) integral to and communicating with a fumes suction duct, and a second open base (7).
- the device comprises further a plurality of internally hollow appendixes, starting from the central body, provided with downwards-directed openings and whose inner recess communicates with the inner volume of the cylinder (1).
- said appendixes comprise a couple of "C" shaped peripheral frames (2) which define a rectangular shape as a whole, the central cylindrical body being arranged therebetween.
- the two frames communicate on the side surface of the central cylindrical body (1) from opposite portions and at the first base (1) and second base (7).
- the first base (11) is configured to communicate with a suction duct conveying the fumes outwards.
- the device comprises also a fumes extraction means (i.e. a fan) configured to suck fumes through said central cylindrical body and to convey them outside through the suction duct.
- a fumes extraction means i.e. a fan
- the fan is introduced inside the fumes suction duct.
- the frames (2) are provided on the inner edges with suction slits (4) which convey in said central cylindrical body (1) the fumes coming from the cooktop (6) through the interspaces (3) made up by the hollow shape of said couple of frames (2).
- the frames (2) are provided, at lower sides, with light sources (13) configured to light up the cooktop (6).
- the device is characterized in that it comprises an extractable container (8), configured to be filled with organic waste and to be introduced inside said central cylindrical body (1) through the opening (7).
- the extractable container (8) has the shape of a half cylinder, and an helicoidal screw (14) is keyed therein, with axis parallel to the axis of the central cylindrical body (1).
- the container is also configured to seal, once introduced, said opening (7) of the central body.
- the helicoidal screw (14) is moved by an electric motor (15) controlled by an electronic unit (5), and is configured to rotate waste and push them, while rotating, towards the bottom of the extractable container (8).
- the bottom of the extractable container is configured to keep the waste introduced therein, and to allow instead the passage of suction fumes.
- the bottom of said extractable container is closed by a net or similar device.
- the device as a whole is configured to suck air from the room - and so also cooking fumes coming from a hot plate under the hood - through suction slits (4), to make them pass through the appendixes inside the central body, and in particular inside the extractable container containing the waste, and so to expel them outside.
- the composting process of organic waste contained in said extractable container (8) is speeded up.
- the device comprises also inside the central cylindrical body (1) an electric resistance (12) for generating heat useful to speed up the composting process of the organic waste contained in the extractable container (8).
- the device comprises also a sensor configured to detect if the extractable container is closed or open, a sensor configured to measure temperature inside the extractable container, and a control unit configured to acquire the data detected by said sensors and to control the air suction means and said electric resistance as a function of said values.
- the hood comprises preferably a sensor for heat detection, and it is configured so that said control unit activates suction and composting of the organic waste contained in the extractable container (8) automatically when heat coming from hot plates (6) is detected.
- a warning light (9) indicating the end of the composting process of the organic waste contained in the container .
- said control unit switches on said warning light when the following conditions are satisfied:
- the extractable container has remained closed for a time longer than the whole time of predetermined treatment; - inside the hood, there are observed temperatures higher than a threshold minimum temperature for a time longer than a whole predetermined time of high temperature treatment.
