Built-in retractable ventilation hood assembly

Abstract

A built-in ventilation hood assembly for air exhausting is disclosed. An example built-in ventilation hood assembly may comprise a housing and a retractable hood unit configured to be slidably mounted within the housing. The retractable hood unit may comprise at least one air intake into which air is drawn. The built-in ventilation hood assembly may further comprise a driving unit configured to slide the retractable hood unit out from the housing or slide the retractable hood unit in to the housing, and a ventilation unit being installed within the housing and configured to draw air in through the at least one air intake.

What is claimed is: 
     
         1 . A built-in ventilation hood assembly for air exhausting, comprising:
 a housing;   a retractable hood unit configured to be slidably mounted within the housing and   wherein the retractable hood unit comprises at least one air intake into which air is drawn;   a driving unit configured to slide out the retractable hood unit from the housing or slide the retractable hood unit into the housing; and   a ventilation unit being installed within the housing and configured to draw air in through the at least one air intake.   
     
     
         2 . The assembly of  claim 1 , wherein the housing is configured to be embedded into a kitchen cabinet above a built-in cooking device. 
     
     
         3 . The assembly of  claim 1 , wherein the housing further comprises one or more guiding members to receive the retractable hood unit. 
     
     
         4 . The assembly of  claim 3 , wherein the guiding members comprise one or more of rails, racks, guides, ramps, ribs, and shafts. 
     
     
         5 . The assembly of  claim 1 , wherein the driving unit comprises at least one electric motor and a transmission unit configured to transmit a force generated by the at least one electric motor to the retractable hood unit. 
     
     
         6 . The assembly of  claim 5 , wherein the transmission unit comprises at least one gear connected with the driving unit and at least one rack coupled to the retractable hood unit. 
     
     
         7 . The assembly of  claim 1 , wherein the ventilation unit comprises at least one of: one or more fans, one or more ducts, and one or more air guiding members. 
     
     
         8 . The assembly of  claim 1 , further comprising a control panel configured to control the driving unit to slide the retractable hood unit in or out, and to control the draw of air through the ventilation. 
     
     
         9 . The assembly of  claim 1 , further comprising at least one air outlet to convey the drawn air flow outside. 
     
     
         10 . The assembly of  claim 9 , wherein the at least one air outlet is configured to be coupled with an external air conduit. 
     
     
         11 . The assembly of  claim 9 , wherein the drawn air flow at least in a part is forced outside the premises in which the built-in ventilation hood assembly is to be mounted. 
     
     
         12 . The assembly of  claim 1 , further comprising a filtering unit configured to treat the drawn air. 
     
     
         13 . The assembly of  claim 14 , wherein the filtering unit comprises a carbon filter. 
     
     
         14 . The assembly of  claim 1 , further comprising one or more illumination devices. 
     
     
         15 . The assembly of  claim 1 , further comprising warning lights to indicate boundaries, angles or walls of the built-in ventilation hood assembly. 
     
     
         16 . The assembly of  claim 15 , wherein the warning lights are automatically powered when the retractable hood unit is extended from the housing. 
     
     
         17 . The assembly of  claim 1 , wherein the retractable hood unit is configured to be retracted from the housing to one or more predetermined lengths.
