Abstract

A vent hood kit comprises a canopy assembly having an intake end and an outlet end, a blower housing selectively and alternatively coupled with the exhaust end of the canopy assembly in an in-line position and an external position, a blower assembly disposed within a blower housing and in communication with the intake end in both the in-line and external positions and an exhaust duct adapter of the blower housing is configured to be in communication with the intake end in both the in-line and external positions.

First claim

What is claimed is:

1. A vent hood kit for a kitchen appliance, the vent hood kit comprising:
a canopy assembly having an intake end and an outlet end;
a removable blower assembly configured to be selectively and alternatively installed between an in-line position and an external position, wherein the removable blower assembly is in communication with the intake end in the in-line and external positions;
a main blower housing fixedly coupled to the outlet end of the canopy assembly, the main blower housing having an exhaust duct adapter and configured to receive the removable blower assembly in the in-line position; and
an accessory blower housing spaced distally from the canopy assembly and having an inlet duct adapter selectively engaged with the exhaust duct adapter, the accessory blower housing configured to receive the removable blower assembly in the external position, wherein the removable blower assembly is selectively movable between the main and accessory blower housing to selectively define the in-line and external positions while the main blower housing is fixedly coupled to the outlet end of the canopy assembly.

2. The vent hood kit of claim 1 , wherein the in-line position is defined by the accessory blower housing being disengaged from the exhaust duct adapter and the removable blower assembly being configured to deliver steam from an area proximate the intake end, through an aperture defined in the exhaust duct adapter and to an area distal from the intake end.

3. The vent hood kit of claim 1 , wherein the external position is defined by the accessory blower housing being engaged with the exhaust duct adapter and the removable blower assembly being configured to deliver steam from an area proximate the intake end, through an aperture defined in an accessory exhaust duct adapter of the accessory blower housing and to an area distal from the intake end.

4. The vent hood kit of claim 3 , wherein a duct extends from the exhaust duct adapter of the main blower housing to the inlet duct adapter of the accessory blower housing when the removable blower assembly is disposed in the external position.

5. The vent hood kit of claim 1 , wherein the removable blower assembly is configured to be selectively disposed between the in-line and external positions.

6. The vent hood kit of claim 1 , wherein the main blower housing includes a plurality of housing walls defining an interior volume, wherein the removable blower assembly is disposed within the interior volume and coupled with at least one of the plurality of housing walls in the in-line position.

7. The vent hood kit of claim 6 , wherein the accessory blower housing includes a plurality of accessory housing walls defining an accessory interior volume, wherein the removable blower assembly is disposed within the accessory interior volume and coupled to at least one of the plurality of accessory housing walls in the external position.

8. The vent hood kit of claim 7 , wherein the plurality of housing walls defines an in-line receptacle and the plurality of accessory housing walls defines an accessory receptacle, and wherein the main blower housing is selectively and alternatively received by the in-line receptacle and the accessory receptacle in the in-line and external positions, respectively.

9. The vent hood kit of claim 1 , wherein a control is configured to operate the removable blower assembly when the removable blower assembly is in either of the in-line and external positions, and wherein a turbulence reduction mechanism is disposed between the intake end of the canopy assembly and one of the exhaust duct adapter of the main blower housing and an accessory exhaust duct adapter of the accessory blower housing.

10. A vent hood kit comprising:
a canopy assembly having an intake end and an outlet end;
a blower housing selectively and alternatively coupled with the outlet end of the canopy assembly in one of an in-line position and an external position;
a blower assembly fixedly disposed within the blower housing and in communication with the intake end in both the in-line and external positions; and
an exhaust duct adapter of the blower housing configured to be in communication with the intake end in both the in-line and external positions, wherein the blower assembly and blower housing are selectively operable between the in-line and external positions; and
a canopy accessory cover that is selectively attached directly to the outlet end of the canopy assembly in the external position, wherein the blower housing is selectively attached directly to the outlet end in the in-line position, the in-line position being free of the canopy accessory cover.

11. The vent hood kit of claim 10 , further comprising:
an inlet accessory cover configured to be selectively attached to an inlet end of the blower housing when the blower assembly is in the external position, wherein the canopy accessory cover and the inlet accessory cover are engaged with one another.

12. The vent hood kit of claim 11 , wherein a duct extends between the canopy accessory cover and the inlet accessory cover when the blower assembly is disposed in the external position, wherein at least one of the canopy assembly, the canopy accessory cover, the inlet accessory cover, the duct and the blower housing includes a noise reduction material.

13. The vent hood kit of claim 10 , wherein an inlet end of the blower housing is attached to the outlet end of the canopy assembly when the blower assembly is in the in-line position.

14. The vent hood kit of claim 10 , wherein the blower assembly is configured to be selectively disposed between the in-line and external positions, and wherein a plurality of intake ports are in communication with the blower assembly, wherein the plurality of intake ports are configured to collect steam from a corresponding plurality of spaces distal from the canopy assembly and direct the steam to the exhaust duct adapter, wherein the plurality of intake ports are engaged with a primary branch adapter that receives ductwork from the corresponding plurality of spaces and directs the steam from the ductwork to the blower assembly.

15. The vent hood kit of claim 10 , wherein the blower housing includes a plurality of housing walls defining an interior volume, wherein the blower assembly is disposed within the interior volume and coupled to at least one of the plurality of housing walls.

16. The vent hood kit of claim 10 , wherein a control is configured to operate the blower assembly when the blower assembly is in either of the in-line and external positions.

17. A vent hood kit comprising:
a blower housing having a plurality of walls defining an inner volume, a blower assembly disposed within the inner volume, and an inlet aperture defined within one of the plurality of walls;
a canopy assembly having an intake end and an outlet end, wherein the outlet end selectively engages the inlet aperture when the blower housing is in one of an in-line position defined by the blower housing being directly connected to the canopy assembly, and an external position defined by the blower housing being distal from the canopy assembly, wherein the blower assembly is in communication with the intake end when the blower housing is in either of the in-line position and the external position, wherein the blower housing includes an integral electrical module that is in selective communication with the canopy assembly and the blower assembly when the blower housing is in either of the in-line and external positions; and
at least one accessory cover that is configured
