Abstract
The device comprises an intake pipe which introduces dry external air into a cooking chamber through an intake. The humid air exits through an outlet pipe connected to an outlet of the cooking chamber; the outlet is located higher than the intake. The outlet pipe is provided with a butterfly valve for regulating a warm air flow. A single-acting valve is predisposed on the intake pipe for allowing a flow of air towards the cooking chamber. The device ensures aspiration of dry external air even where there are no means for forced air circulation.
Claims10
1). A device for de-humidifying a cooking chamber in an apparatus for food cooking, comprising:
- at least one intake pipe, having a first end connected to an inlet of the cooking chamber, and at least a second end, opposite to the first end, which is connected to an external environment;
- at least one outlet pipe having a first end connected to an outlet of the cooking chamber, which outlet is located higher than the inlet, and a second end, opposite the first end, which is connected to an external environment;
- wherein the device comprises at least one intercept device of a flow of air, predisposed on the at least one outlet pipe.
2). The device of claim 1, wherein the at least one intercept device comprises a valve for regulating the flow of air along the outlet pipe.
3). The device of claim 2, comprising a single-acting valve predisposed on the at least one intake pipe for allowing the flow of air to move towards the cooking chamber.
4). The device of claim 3, wherein the single-acting valve is closed by effect of an overpressure in the cooking chamber.
5). The device of claim 4, characterised in that the single-acting valve operates in a vertical tract of the at least one intake pipe and is provided with a shutter which is normally open by effect of a weight thereof, and which is raised into a closed position by effect of a pressure difference.
6). The device of claim 4, wherein the single-acting valve and the at least one intake pipe act as safety devices in a presence of sharp temperature drops.
7). The device of claim 4, comprising a sensor which is predisposed to regulate a humidity in the cooking chamber by sending a signal used for controlling the intercept device.
8). The device of claim 4, comprising means for creating a slight overpressure in the cooking chamber.
9). The device of claim 8, wherein the means for creating a slight overpressure comprise a discharge having a syphon on a bottom of the cooking chamber.
10). The device of claim 9, wherein the means for creating a slight overpressure further comprise an overpressure valve which opens by effect of a predetermined pressure in the cooking chamber.
