Definitions
- the present invention relates to a cooling and exhaust system, in particular for a cooking oven. Further, the present invention relates to a cooking oven with a cooling and exhaust system.
- Cooling and exhaust systems usually operate with either an axial fan or cross-flow fan.
- the cooling and exhaust systems with the axial fan provide good results in the high efficiency of a fan shroud.
- Said fan shroud is able to generate high pressure and an air flow throughout the cooling and exhaust system.
- the axial fan is expensive and results in high costs of the whole cooling and exhaust system.
- the cooling and exhaust systems with the cross-flow fan causes only low costs and a good efficiency.
- the cooling and exhaust system with the cross-flow fan is installed above an oven cavity of the cooking oven and directly on a driving plate.
- a discharging channel of the cooling and exhaust system extends from the rear portion to a front portion of the cooking oven. Vapour and/or hot air are eliminated through the lower part of a control panel of the cooking oven, but sometimes through the upper part of said control panel.
- FIG 6 illustrates a schematic sectional side view of the cooling and exhaust system 40 and a corresponding pressure-space-diagram according to the prior art.
- the upper picture represents the cooling and exhaust system 40, while the pressure-space-diagram is shown by the lower picture.
- the cooling and exhaust system 40 comprises a fan shroud 12 and a discharging channel 14.
- An impeller 16 with a plurality of fan blades 18 is arranged inside the fan shroud 12.
- the rotation axis of the impeller 16 extends perpendicular to the plane of the drawing, and the impeller 16 rotates counterclockwise.
- the fan shroud 12 and the impeller 16 form a cross-flow fan.
- An inlet 42 is arranged above the impeller 16.
- the impeller 16 is driven by an electric motor.
- the impeller 16 rotates in the direction of the action of the forwardly inclined fan blades 18 and generates a strong suction of an air stream from the inlet 42.
- the air stream follows via a path through the fan shroud 12 and the discharging channel 14 to an outlet 24.
- An exhaust pipe 32 is installed in the bottom of the discharging channel 14 and communicates with the ceiling of the oven cavity.
- an air suction and a low pressure zone occurs in the exhaust pipe 32, which extracts the vapours from the oven cavity due to the air stream in the discharging channel 14.
- the vapours follow the same path as the air stream from the inlet 42 to the outlet 24.
- the cooling and exhaust system is provided for cooling the components above the oven cavity on the one hand and eliminating the vapours released from the cavity.
- the pressure-space-diagram in the lower picture of FIG 6 shows the distribution of the static pressure along the cooling and exhaust system 40.
- the static pressure may have positive and negative values.
- the distribution of the static pressure depends on the geometry of the fan shroud 12 and on the inner shapes of the cooling and exhaust system 40.
- Experimental results have shown that the suction pressure remains low around the zone of the exhaust pipe 32 during the operation of the cross-flow fan, since the airflow incident angle relative to the horizontal base plate 30 has a low value.
- the low static pressure in the zone of the exhaust pipe 32 is disadvantageous, since a consistent mass of vapour remains inside the oven cavity. Further, the low static pressure in the zone of the exhaust pipe 32 is disadvantageous for the energy consumption.
- the object of the present invention is achieved by the cooling and exhaust system according to claim 1.
- the cooling and exhaust system comprises a fan shroud and a discharging channel, wherein

- a bottom side of the fan shroud is at least partially open, wherein a portion of said bottom side is closed or closable by a base plate, and wherein the base plate is either a part of the cooling and exhaust system or of the cooking oven.
- the position of the base plate may be variable.
- an air stream through the cooling and exhaust system follows a path defined by the geometry of the cooling and exhaust system in a predetermined manner.
- the flow of the air stream through the first inlet is bigger than the flow of the air stream through the second inlet.
- a main air stream is sucked through the first inlet, while the second inlet sucks an additional air stream.
- an exhaust pipe may be arranged in the bottom of the discharging channel, so that the discharging channel is connected or connectable to an oven cavity of the cooking oven.
- the structure of the two inlets, the one outlet and the exhaust pipe allows a high negative static pressure in the discharging channel, so that vapours can be removed from the oven cavity of the cooking oven and exhausted through the discharging channel.
- the impeller is driven by an electric motor energized by alternating or direct current.

- a bigger part of the sucked air stream passes the first inlet 20, while a smaller part of the sucked air stream passes the second inlet 22.
- a large mass of fresh air is sucked by the impeller 16 through the first inlet 12 and creates a main air stream inside the cooling and exhaust system 10.
- said fresh air is sucked from the space around the control panel of the cooking oven, wherein the air around the control panel is replaced by another fresh air pulled into the oven casing from the external environment of the cooking oven.
- the control panel and its components may be cooled down by the air from the external environment.
- the smaller part of the air stream sucked by the impeller 16 passes the second inlet 22.

- the air at the rear side of the oven cavity is generated by heating elements of the cooking oven and accumulated at said rear side of the oven cavity.
- the second inlet 22 compensates the difference between the air flows of the outlet 24 and the first inlet 20.
- the mass of the air stream circulating in the cooling and exhaust system 10 has permanently a constant value.
- the sum of both air streams from the first inlet 20 and second inlet 22 form an air stream 36 inside the discharging channel 14.
- the air stream 36 exhausts through the outlet 24 at the open end of the discharging channel 14.
- the air stream from the second inlet 22 deflects the sum of both air streams from the first inlet 20 and second inlet 22, so that the direction of said sum of both air streams has an airflow incident angle 38 with a high value relating to the base plate 30.
- This is a result of Bernoulli law, in which the sum of the potential energy, kinetic energy and pressure remains constant along a closed aerodynamic channel.

- An exhaust pipe 32 is arranged in the bottom of the discharging channel 14.
- the exhaust pipe 32 is connected or connectable with a ceiling of the oven cavity.
- the air stream from the second inlet 22 causes the relative high negative pressure above the exhaust pipe 32. This results in a relative high suction force of the air stream 34 through the exhaust pipe 32. Said high suction force causes of a relative big amount of extracted vapours from the oven cavity.
- the vapours follow the same path as the air stream 36 inside the discharging channel 14.
- the cooling and exhaust system 10 is provided for cooling components above the oven cavity on the one hand and eliminating vapours released from the oven cavity.
