Frontal cooling towers for a ventilation system of a cooking appliance
First Claim
1. A cooking appliance comprising:
- a housing having a sidewall and a front panel, wherein a heating cavity is defined within the housing;
an operable door panel rotationally coupled proximate the front panel and operable to provide selective access to the heating cavity via an aperture defined within the front panel;
a heat source in thermal communication with the heating cavity and the front panel;
a blower disposed within an interstitial space at least partially defined by an outer surface of the housing; and
a ventilation tower attached to the sidewall and positioned proximate the front panel, wherein selective operation of the blower draws ventilation air from an external region proximate the front panel and into the interstitial space via the ventilation tower,wherein the ventilation tower is positioned adjacent a handle of the operable door panel, wherein movement of the ventilation air at least partially limits thermal communication between the heat source and the handle.

Abstract
A cooking appliance includes a housing having a sidewall and a front panel, wherein a heating cavity is defined within the housing. An operable door panel is rotationally coupled proximate the front panel and operable to provide selective access to the heating cavity via an aperture defined within the front panel. A heat source is in thermal communication with the heating cavity and the front panel. A blower is disposed within an interstitial space at least partially defined by an outer surface of the housing. A ventilation tower is attached to the sidewall and positioned proximate the front panel. Selective operation of the blower draws ventilation air from an external region proximate the front panel and into the interstitial space via the ventilation tower.

8. A heating and ventilation system for a cooking appliance, the heating and ventilation system comprising:
-
a heat source that selectively delivers heat to a heating cavity defined within a housing; an outer ventilation path that extends around at least a portion of an exterior of the housing; a ventilation tower disposed proximate a sidewall of the housing and in communication with the outer ventilation path; a blower disposed within the outer ventilation path and selectively operable to move ventilation air from the ventilation tower and into the outer ventilation path, wherein the ventilation tower includes a side vent that cooperates with the blower to direct cooling air from areas external to the outer ventilation path into the ventilation tower to at least partially define the ventilation air; an operable door panel coupled to the housing proximate a front panel of the housing, wherein the operable door panel provides selective access to the heating cavity via an aperture defined within the front panel; and a handle attached to the operable door panel, wherein the ventilation tower is positioned adjacent the front panel and proximate the handle of the operable door panel, wherein movement of the ventilation air through the side vent at least partially limits thermal communication from the heat source and to the handle. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A heating appliance comprising:
-
an upper housing including an upper heat source that delivers heat to an upper heating cavity defined within the upper housing; a lower housing including a lower heat source that delivers heat to a lower heating cavity defined with in the lower housing; a heating and ventilation system that includes an outer ventilation path extending around an outer surface of each of the upper and lower housings; upper and lower ventilation towers disposed at sidewalls of the upper and lower housings, respectively, each of the upper and lower ventilation towers in communication with the outer ventilation path; at least one blower disposed within the outer ventilation path and selectively operable to move ventilation air from at least one of the upper and lower ventilation towers and into the outer ventilation path, wherein each ventilation tower of the upper and lower ventilation towers includes a side vent that cooperates with the at least one blower to direct cooling air from areas external to the outer ventilation path and the upper and lower housings and into the outer ventilation path to partially define the ventilation air; an upper door coupled to the upper housing, wherein the upper door provides selective access to the upper heating cavity; and an upper handle attached to the upper door, wherein the upper ventilation tower is positioned proximate the upper handle, wherein movement of the ventilation air through the side vent of the upper ventilation tower and into the outer ventilation path at least partially limits thermal communication from the upper heat source and to the upper handle. - View Dependent Claims (16, 17)
