Claims12
In a ventilating system for a surface cooking appliance having a ventilating duct extending downwardly through a generally horizontal surface adjacent at least one cooking unit, and a ventilator mounted for vertical movement with respect to said duct and having a lowermost position and an uppermost position, the improvement wherein said ventilator has a substantially rectangular horizontal top having a front edge, a pair of opposite side edges, and a rear edge, said top being shaped to cover and substantially seal the upper end of said duct in said lowermost position of said ventilator, vertical support means extending downwardly from said adjacent the front edge of said top for selectively holding said ventilator at said lowermost position and said uppermost position wherein said top is substantially above said surface, said ventilator having a substantially open side extending downwardly from one of said side edges and being substantially completely open between said top and said surface when said ventilator is in said uppermost position, and a flat vertically oriented filter mounted to substantially completely and removably cover said open side of said ventilator and to move vertically with said ventilator, said vertical support means comprising substantially the sole support for said top.
In a ventilating system for a surface cooking appliance having a ventilating duct extending downwardly through a substantially horizontal surface adjacent a cooking element, and a ventilator mounted for vertical displacement with respect to said duct;
- the improvement wherein said duct has a substantially rectangular cross section, said ventilator has a vertical plate means vertically slidably mounted in said duct to a wall thereof and defining the front of said ventilator, a top depending from and being substantially solely supported by said plate means, said top being shaped to cover the upper end of said duct means in a lowermost position of said ventilator, the sides of said ventilator adjacent said front being substantially completely open between said surface and top in the uppermost position of said ventilator, recesses being provided on both sides of said ventilator adjacent the open sides thereof, and separate planar vertical filters removably mounted in said recesses to cover each of the open sides thereof.
In a ventilating system for a surface cooking appliance having a substantially rectangular ventilating duct extending downwardly through a substantially horizontal surface adjacent at least one cooking element, and a ventilator having a substantially rectangular cross section and mounted for vertical displacement with respect to said duct;
- the improvement wherein said ventilator comprises a vertical plate means defining the front of said ventilator, a vertically extending track on the front inner wall of said duct, said plate means having a vertically extending guide mounted thereon and slidably engaging said vertically extending track, said guide and track serving as the sole support for said ventilator, said ventilator further having a substantially horizontal top depending from said plate means and shaped to cover the upper end of said duct means in the lowermost position of said ventilator, and a rear covering the back side of said ventilator, at least one side of said ventilator being substantially completely open between said top and surface in the uppermost position of said ventilator and being removably covered by at least one planar vertically oriented filter.
