Abstract

A modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith for exploitation in a ventilation device or system.

1 . A modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith, 
 said interconnection element being configured for interconnecting said pair of modular blower sub-assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration,    each of said modular blower sub-assemblies comprising blower means and an enclosure disposed about said blower means,    said blower means having an upstream side and a downstream side,    said enclosure comprising a pair of opposed faces interconnected by side wall means,    said enclosure having an axis of rotation relative to said opposed faces,    one of said opposed faces defining a blower opening in air communication with one side of the blower means, the blower means having an axis of rotation transverse to said one opposed face,    said side wall means defining a side blower opening in air communication with the other side of the blower means,    said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass through said side blower opening in a first direction and being configured to be able, on rotation of the enclosure about said axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass through said side blower opening in a second direction transverse to said first direction.    
     
     
         2 . A modular blower assembly for association with an interconnection element configured for interconnecting a pair of modular blower assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration, said modular blower assembly comprising blower means and an enclosure disposed about said blower means, 
 said blower means having an upstream side and a downstream side,    said enclosure comprising a pair of opposed faces interconnected by side wall means,    said enclosure having an axis of rotation relative to said opposed faces,    one of said opposed faces defining a blower opening in air communication with one side of the blower means, the blower means having an axis of rotation transverse to said one opposed face,    said side wall means defining a side blower opening in air communication with the other side of the blower means,    said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass through said side blower opening in a first direction and being configured to be able, on rotation of the enclosure about said axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass through said side blower opening in a second direction transverse to said first direction.    
     
     
         3 . A modular blower combination assembly comprising an interconnection element and a pair of modular blower sub-assemblies associated therewith, 
 said interconnection element configured for interconnecting said pair of modular blower sub-assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration,    each of said modular blower sub-assemblies comprising blower means and an enclosure disposed about said blower means,    said blower means having an upstream side and a downstream side,    said enclosure having a rectangular box-like form and comprising a pair of opposed square broad faces interconnected by a first side wall element and three secondary side wall elements, said enclosure having a central axis of rotation relative to said opposed square broad faces,    one of said opposed broad faces defining a blower air intake opening in air communication with the upstream side of the blower means, the blower means having an axis of rotation transverse to said one opposed face,    said first side wall element defining a side blower air outlet opening in air communication with the downstream side of the blower means,    said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass out of said side blower opening in a first direction and being configured to be able, on rotation of the enclosure 90 degrees about said central axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass out of said side blower opening in a second direction perpendicular to said first direction.    
     
     
         4 . A modular blower combination assembly as defined in  claim 1  wherein the interconnection element comprises an elongated element and has an L-like cross-section having a foot portion and a upstanding leg portion connected thereto, said foot portion being configured for seating said enclosure by engagement with a secondary side wall element.  
     
     
         5 . A modular blower assembly for association with an interconnection element configured for interconnecting a pair of modular blower assemblies in juxtaposed relationship in a respective first configuration and in a respective second configuration, 
 said modular blower sub-assembly comprising blower means and an enclosure disposed about said blower means,    said blower means having an upstream side and a downstream side,    said enclosure having a rectangular box-like form and comprising a pair of opposed square broad faces interconnected by a first side wall element and three secondary side wall elements, said enclosure having a central axis of rotation relative to said opposed square broad faces,    one of said opposed broad faces defining a blower air intake opening in air communication with the upstream side of the blower means, the blower means hsving sn axis of rotation transverse to said one opposed face,    said first side wall element defining a side blower air outlet opening in air communication with the downstream side of the blower means,    said enclosure being configured to be able to engage said interconnection element in a first configuration whereby said side blower opening is disposed in a first position such that air may pass out of said side blower opening in a first direction and being configured to be able, on rotation of the enclosure  90  degrees about said central axis of rotation of the enclosure, to engage said interconnection element in a second configuration whereby said side blower opening is disposed in a second position such that air may pass out of said side blower opening in a second direction perpendicular to said first direction.
