Arrangement in the ventilation of a kitchen appliance
The invention relates to an arrangement in the ventilation of a kitchen appliance. The arrangement is arranged to be connected to a ventilation system. The arrangement includes at least one hood ( 10 ), which is intended to be installed above the kitchen appliance ( 11 ). There is an exhaust-air connection ( 27 ) in each hood ( 10 ), for connecting the hood ( 10 ) to the exhaust-air duct ( 12 ) belonging to the ventilation system. The arrangement also includes a separator ( 15 ), for separating grease form the exhaust air. The arrangement further includes a cell ( 14 ), which is arranged after the hood ( 10 ) and is separate from the hood ( 10 ), and to which a separator ( 15 ) is fitted, and which is connected to the exhaust-air duct ( 12 ).
1. An arrangement in the ventilation of a kitchen appliance, which arrangement is arranged to be connected to a ventilation system including an exhaust-air duct, said arrangement comprising:
a hood which is intended to be installed above the kitchen appliance, and said hood not including any of a sensor, a damper, a water bath, and a heat exchanger;
said hood including an elongated exhaust-air connection for connecting said hood to the exhaust-air duct;
a separator for separating grease from the exhaust air;
a cell arranged after said hood limiting an area in which the vaporous grease condenses;
said cell mounting said separator at an end connected to said exhaust-air duct and having a connection at another end connected to said elongated exhaust-air connection to lead exhaust-air away from the hood;
said cell including an intake-air connection for introducing non-exhaust air into the cell to reduce the temperature of the exhaust air, for promoting the formation of droplets of vaporized grease,
said cell including a temperature sensor for sensing temperature within said cell;
said arrangement also including one of a heat exchanger, a fan motor, and a damper arranged in connection with said intake-air connection for regulating the velocity, quantity, and/or temperature of the intake air, and the heat exchanger, the motor, and the damper are connected to the temperature sensor for controlling them.
2. An arrangement according to claim 1 , characterized in that the cell is an elongated structure and the connection is fitted to the opposite end of the cell to the separator.
3. An arrangement according to claim 1 , characterized in that the ventilation system, the cell is fitted essentially horizontally relative to its longitudinal axis.
4. An arrangement according to claim 1 , characterized in that, in order to feed intake air into the exhaust air, the cell includes a distribution duct and nozzle elements connected to it.
5. An arrangement according to claim 1 , characterized in that the intake-air connection is connected to the intake-air duct belonging to the ventilation system.
6. An arrangement according to claim 1 , characterized in that the cell includes baffle elements for guiding the flow of the exhaust air in the cell.
7. An arrangement according to claim 1 , characterized in that the cell includes washing elements for distributing washing liquid to the cell and/or the separator.
8. An arrangement according to claim 1 , characterized in that the width of the cell is 1.1-2.0 times the width of the exhaust-air duct.
9. An arrangement according to claim 1 , characterized in that the length of the cell is 2-6 times the width of the cell.
10. An arrangement according to claim 1 , characterized in that the cubic capacity of the cell is at least 10% of the minute volume of the flow of exhaust air.
11. An arrangement according to claim 1 , characterized in that the non-exhaust air is arranged to alter the flow of the exhaust air.
