Detailed Description
With reference to the figures outlined above, the present invention proposes a cooking device (1) comprising: a cavity (2) defining an open volume in which any cooking process takes place; an upper wall (3) placed on top of the cavity (2); at least one flue (4) on the upper wall (3) for filtering fumes and air inside the cavity (2); at least one external channel (6) and at least one internal channel (7) configured to be implemented in the flue (4) for filtering the exhaust air (H); at least one negative electrode (8) for placement adjacent to the internal channel (7); at least one positive electrode (9) for placement adjacent to the external channel (6); and at least one power supply (10) for generating an electric field between the negative electrode (8) and the positive electrode (9).
Referring now in detail to the drawings and initially in particular to fig. 1 thereof, a cooking device (1) having a flue (4) is shown. The chimney (4) is placed on the upper wall (3) of the cavity (2) for exhausting fumes and air inside the cavity (2) during the cooking process. Preferably, the flue (4) is centrally located in the upper wall (3) for providing better gas discharge. The present invention relates to a new flue (4), said flue (4) comprising nested channels.
As shown in fig. 2, at least one external channel (6) and at least one internal channel (7) are implemented inside the flue (4). An internal passage (7) is located inside the cavity (2) at the inlet of the flue (4), said internal passage (7) being in direct contact with the exhaust air (H) from the cavity (2). Two associated internal channels (7) are associated with the negative electrode (8). Additionally, two associated external channels (6) are placed parallel to each other. Has at least one positive electrode (9) placed adjacent to each external channel (6), preferably parallel to each external channel (6). The negative electrode (8) may be a metal mesh for placement between the two internal channels (7) and the positive electrode (9) may be a tubular metal plate for placement adjacent to the external channels (6).
The power supply (10) is used for supplying high voltage to generate an electric field. The power supply is connected to the flue (4) by means of any connection unit, preferably by means of a cable. As can be seen in fig. 2, the power supply has a positive end (101) and a negative end (102), the positive end (101) being configured to be coupled to the positive electrode (9) and the negative end (102) being configured to be coupled to the negative electrode (8).
Firstly, by contact with the negative electrode (8), the exhaust air (H) from the cavity (2) passes through the internal passage (7) to the flue (4). Thus, all of the odor molecules in the exhaust air (H) are negatively charged with the negative electrode (8) and the negative end (102) of the power supply (10). Subsequently, negatively charged exhaust air molecules (X) move through the flue (4) and are directed to the area surrounding the external channel (6). Has two positive electrodes (9) placed adjacent to the external channel (6) parallel thereto. The positive electrode (9) is preferably a positively charged tubular metal plate. At least one positive electrode end (101) of the power supply source (10) is connected to the positive electrode (9). During passage through the flue (4), negatively charged exhaust air molecules (X) accumulate on the positive electrode (9) due to the electric field generated by the high voltage power supply (10). Thus, negatively charged exhaust air molecules (X) are trapped by the positive electrode (9) before leaving the flue (4) to the outside of the cooking device (1). The filtered air (F) flowing out of the flue (4) is thus discharged from the cooking device (1) in a clean and odorless manner.
In addition to this, when the power supply (10) is switched off and the electric field is removed, negatively charged exhaust air molecules (X) accumulated inside the flue (4) slide down through the gap between the outer channel (6) and the inner channel (7) and accumulate in the collection chamber (5) at the bottom of the flue (4). This readily accessible collection chamber (5) inside the cavity (2) can be easily removed by the user and cleaned by the user. The collection chamber (5) is fitted to the flue (4) by means of a connecting member (11). The connecting member (11) may be a jaw fit, threaded connection or tight fit for providing a durable assembly.
