Definitions
- the present invention relates to a cooling and exhaust system, in particular for a cooking oven, according to the preamble of claim 1. 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.
