Abstract

A countertop oven includes a housing having a rear panel, an upper panel, a bottom panel, a first side panel, an opposing second side panel and an open front end, together defining a cooking cavity therebetween. The cooking cavity is accessible via the open front end of the housing. At least one heating element within the housing selectively heats the cooking cavity. A door is movably attached to the housing via at least one 4-bar linkage mechanism. The door is selectively movable between a closed position, wherein the open front end of the housing is covered by the door, and an open position, wherein the door is positioned generally atop the upper panel of the housing, thereby uncovering the open front end of the housing to access the cooking cavity.

Claims (18)

1. A countertop oven comprising:

a housing having a rear panel, an upper panel, a bottom panel, a first side panel, an opposing second side panel and an open front end, together defining a cooking cavity therebetween, the cooking cavity being accessible via the open front end;

at least one heating element within the housing to selectively heat the cooking cavity; and

a door movably attached to the housing via at least one 4-bar linkage mechanism, the door being selectively movable between a closed position, wherein the open front end of the housing is covered by the door, and an open position in which the door is positioned generally atop and parallel to the upper panel, thereby uncovering the open front end of the housing to access the cooking cavity, and

wherein the 4-bar linkage mechanism comprises a first rocker bar pivotably attached at one end thereof to the door and pivotably attached at an opposing end thereof to the first side panel of the housing, and a second rocker bar pivotably attached at one end thereof to the door and pivotably attached at an opposing end thereof to the first side panel of the housing, the oven housing defining a ground link of the 4-bar linkage mechanism and the door defining a coupler link of the 4-bar linkage mechanism movable between the open and closed positions thereof.

2. The countertop oven of claim 1 , wherein the pivotable attachment between the first rocker bar and the door is positioned proximate a first edge of the door, and the pivotable attachment between the second rocker bar and the door is positioned proximate an opposing second edge of the door.

3. The countertop oven of claim 1 , wherein the pivotable attachment between the second rocker bar and the door is selectively releasable to disengage the door from the second rocker bar and enable the door to pivot about the pivotable attachment between the first rocker bar and the door.

4. The countertop oven of claim 3 , wherein the pivotable attachment between the second rocker bar and the door comprises a pin at the end of the second rocker, the pin being biased into a corresponding aperture in the door, and the pin being selectively depressible to release the door from the second rocker bar.

5. The countertop oven of claim 1 , wherein the door includes a glass panel, the glass panel being pivotably attached to the door at one end thereof and selectively, removably latched to the door at an opposing end thereof, wherein unlatching of the opposing end of the glass panel from the door permits pivoting of the glass panel relative to the door.

6. The countertop oven of claim 5 , wherein the glass panel comprises a latching member biased into a corresponding slot in the door, the latching member being selectively retractable from the slot to unlatch the glass panel from the door.

7. The countertop oven of claim 1 , wherein the door includes a first side panel and an opposing second side panel, the first side panel of the door being permanently coupled to the first side panel of the housing via the 4-bar linkage mechanism.

8. The countertop oven of claim 1 , wherein the door includes a glass panel, the glass panel being selectively detachable from the door.

9. The countertop oven of claim 8 , wherein the glass panel is removably latched to the door, and unlatching of the glass panel from the door permits detaching the glass panel from the door, the glass panel being selectively re-attachable to the door.

10. The countertop oven of claim 9 , wherein the glass panel comprises a latching member biased into a corresponding slot in the door, the latching member being selectively retractable from the slot to unlatch the glass panel from the door.

11. The countertop oven of claim 1 , wherein each of the rear panel, the upper panel, the bottom panel, the first side panel, and the opposing second side panel of the housing are generally planar.

12. The countertop oven of claim 1 , wherein the door is spaced upwardly from the upper panel of the housing by between approximately 15 mm to approximately 40 mm, in the open position of the door.

13. The countertop oven of claim 1 , wherein the door includes a first side panel, an opposing second side panel, and a front panel extending therebetween, the front panel including a glass panel, the glass panel being at least one of pivotably and removably attached to the front panel.

14. The countertop oven of claim 1 , wherein the 4-bar linkage mechanism is a 4-bar quadrilateral linkage mechanism.
