Motorized extractor hood for kitchens of vertical sliding type

Abstract

The present invention relates to a motorized extractor hood for kitchens, of the type housed and vertically sliding inside a vertical compartment ( 2 ) obtained on the back of the cabinet (M) in which the oven and/or stove is installed, which also contains an actuator ( 3 ) designed to move the hood that comprises a specularly opposite pair of identical vertical racks ( 5 ), respectively fixed onto the lateral walls ( 2 b ) of the compartment ( 2 ), which engage with corresponding sprocket wheels ( 6 ) coupled at the two ends of a horizontal shaft ( 7 ) revolvingly supported by the hood ( 1 ).

1 . Motorized extractor hood for kitchens, which is housed and vertically slides inside a vertical compartment ( 2 ) obtained on the back of the cabinet (M) in which the stove is installed, and comprising an actuator ( 3 ,  30 ) used for sliding, characterised in that it also comprises a specularly opposite pair of identical vertical racks ( 5 ), respectively fixed onto the lateral walls ( 2   b ) of the compartment ( 2 ), which engage with corresponding sprocket wheels ( 6 ) coupled at the two ends of a horizontal shaft ( 7 ) revolvingly supported by the hood ( 1 ). 
   
   
       2 . Motorized extractor hood for kitchens according to  claim 1 , characterised in that the actuator ( 3 ) is fixed onto the bottom wall ( 2   a ) of the said compartment ( 2 ). 
   
   
       3 . Extractor hood according to  claim 1 , characterised in that the actuator ( 3 ) consists in a jack ( 3 ) with vertical axis, with motor-driver pump ( 4 ) mounted on the bottom of the said compartment ( 2 ), the stem ( 3   a ) of the jack ( 3 ) being coupled in the centre of the lower side ( 1   a ) of the hood ( 1 ), and the cylinder ( 3   b ) being fixed to the bottom wall ( 2   a ) of the said compartment ( 2 ). 
   
   
       4 . Extractor hood according to  claim 1 , characterised in that the actuator ( 30 ) consists in an electrical motor ( 30 ) mounted on board the hood ( 1 ), which drives the shaft ( 7 ) into rotation. 
   
   
       5 . Extractor hood according to  claim 1 , characterised in that the shaft ( 7 ) runs near and parallel to the lower side ( 1   a ) of the hood ( 1 ), from which it protrudes laterally only with the two ends where the said sprocket wheels ( 6 ) are coupled.
