The present disclosure generally relates to an oven, and more specifically, to an oven with a tilting broiler assembly for increasing the efficiency of a pyrolytic cleaning cycle.
Many existing ovens are equipped with self-cleaning functionality, wherein the main heating element and broiler are powered on high for a time sufficient to heat the walls of the interior oven cavity to a temperature in the order of about 475° C. (887° F.), which is generally sufficient to burn any residue thereon to the point of disintegration or detachment from the walls. Notably, the position of the main heating element adjacent to the lower wall (or cavity floor) takes a far shorter time interval to reach about 475° C. (887° F.) (e.g. less than two hours), with the side walls and the back wall taking a far longer time (e.g. at least four hours) to reach the same temperature. In this respect, it has been observed that the overall time needed to run a self-cleaning cycle can be reduced with additional solutions for cleaning/heating the back wall and side walls.
According to one aspect of the present disclosure, an oven includes an interior liner defining an interior cavity between two generally parallel, spaced-apart side walls, a top wall extending between the two side walls, and a back wall extending downwardly from the top wall. The oven further includes a broiler element mounted within the interior liner and moveable between a cooking position, wherein the broiler element extends laterally along the top wall in a direction between the two side walls and longitudinally away from the back wall, and a cleaning position, wherein the broiler element extends laterally along the back wall in the direction between the two side walls and vertically away from the top wall.
According to another aspect of the present disclosure, a broiler assembly for an oven includes a broiler element configured for resistive heating and first and second hinges connected to opposite ends of the broiler element. The first and second hinges are configured to electrically and mechanically connect with an oven. The mechanical connection moveably supports the broiler element within a cavity of the oven in alternating cooking and cleaning positions and the electrical connection facilitates an electrical connection with the oven for effecting heating of the broiler element. The broiler assembly further includes a shield affixed to at least a portion of the broiler element such that the shield moves with the broiler element between the cooking position and the cleaning position.
According to yet another aspect of the present disclosure, a method for cleaning an oven includes moving a broiler element mounted within an interior cavity of the oven. The interior cavity is defined by an interior liner defining an interior cavity between two generally parallel, spaced-apart side walls, a top wall extending between the two side walls, and a back wall extending downwardly from the top wall. The broiler element is moved from a cooking position, wherein the broiler element extends laterally along the top wall in a direction between the two side walls and longitudinally away from the back wall, to a cleaning position, wherein the broiler element extends laterally along the back wall in the direction between the two side walls and vertically away from the top wall. The method further includes powering the broiler element and the main heating element of the oven at temperatures in the order of 475° C. (887° F.) e.g. for less than 2.5 hours, thereby carrying out a pyrolytic cleaning cycle.
These and other features, advantages, and objects of the present disclosure will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.

In a particular aspect, the broiler element 24 can be included in a broiler assembly 26 that further includes a shield 28 affixed to at least a portion of the broiler element 24 such that the shield 28 moves with the broiler element 24 between the cooking position P1 and the cleaning position P2. In this arrangement, a major shield wall 30 of the shield 28 is disposed between the top wall 20 and the broiler element 24 when the broiler assembly 26 is in the cooking position P1. By mounting the broiler element 24 on the shield 28 that sits above the broiler element 24 in the cooking position P1, the shield 28 is positionable against the top wall 20 of the cavity 14. In this manner, the shield 28 effectively covers the top wall 20 and becomes the upper boundary of the cavity 14 during cooking, including with the broiler element 24 in the cooking position P1. As shown, the shield 28 can define a concave inner portion 32 by way of a perimeter wall 34 surrounding the major surface 30 extending away therefrom and downward, in the vertical direction V (when the broiler assembly 26 is in the cooking position P1, as shown in
As further shown in

After removal of the side panel inserts 40 and 42, the broiler assembly 26 can be released from the cooking position P1 for lowering into the cleaning position P2. In the depicted example, the broiler assembly 26 includes a retention pin 46 that engages a portion of the interior liner 12 to maintain the broiler assembly 26 in the cooking position P1 against the force of gravity, which generally urges the broiler assembly 26 toward the cleaning position P2. The retention pin 46 is releasable from the portion of the interior liner 12 to allow movement of the broiler assembly 26 into the cleaning position P2. In the illustrated example, the pin 46 engages with an intermediate face 48 of the liner 12 that extends between the top wall 20 and an outer flange 50 of the liner 12, although other arrangements are possible. Additionally, in the depicted example, the pin 46 is rigidly coupled or otherwise formed with a knob 52 to facilitate grasping of the pin 46 and outward pulling thereof by the user against the inward biasing of the pin 46. In the depicted example, the broiler assembly 26 includes two such pins 46 with connected knobs 52 in spaced apart-locations along the shield 28 and engaging with respective holes 54 in the inner face 48 of the liner 12 for additional support for the broiler assembly 26 in the cooking position P1 and to prevent inadvertent releasing of the broiler assembly 26.

As shown, the hinges 56a and 56b each include a first hinge portion 64a and 64b connected at each end 58a and 58b of the broiler element 24. The first hinge portions 64a and 64b surround the ends 58a and 58b of the broiler element 24 that extend through the apertures 60a and 60b in the shield 28 by being in the form of ceramic insulating sleeves that are positioned between the ends 58a, 58b and the apertures 60a and 60b. Second hinge portions 66a and 66b respectively connect with the first hinge portions 64a and 64b. In particular, the second hinge portions 66a and 66b can each include a receiver 70 that rotatably couples with a connector 72 fixed on the above-described first hinge portions 64a and 64b. As shown, the receiver 70 is defined by a conductive disc 74 with two axles 76 laterally extending therefrom. The connector 72 is defined by a pair of conductive discs 74 spaced apart from each other by a distance generally corresponding with the thickness of the conductive disc 74 of the receiver 70 such that the disc 74 of the receiver 70 can fit therebetween. The conductive discs 74 of the connector 72 each define apertures 78 that receive the axles 76 of the receiver 70 to couple the connector 72 to the receiver 70 in the above-described rotatable manner. In this respect, the centers of the axles 76 and apertures 78 are aligned with and/or define the hinge point 36 about which the broiler assembly 26 rotates.
As further shown, each receiver 70 is rigidly coupled with a post 80 such that the rotation of the connector 72 relative to the receiver 70 facilitates movement of the broiler assembly 26, including the broiler element 24, relative to the sleeve posts 80. The posts 74a and 74b are each configured to extend through a respective aperture 82 in the liner 12. In the depicted example the apertures 82 are defined within the top wall 20, although other arrangements are possible. The posts 80 extend through the apertures 82 for mechanical connection with the oven 10 and, accordingly, may further engage with respective plug holes therein that are mechanically supported above the top wall 20 of the liner 12. The above-described ends 58a and 58b extend away from the hinge point 36 in a direction perpendicular to an axis of the respective posts 74a and 74b when in the cooking position P1 and parallel to the axis when in the cleaning position P2, as shown in the figures. As shown in
As can be appreciated, the oven 10 can further include a controller 88 configured to execute a cooking mode, including by causing heating of the broiler element 24, and a cleaning mode, including operating the broiler element 24, for pyrolytic cleaning of the back wall 22. As discussed above, the present arrangement can facilitate cleaning of the back wall 22 during a cleaning cycle that lasts for less than two-and-a-half hours. In this respect, an additional aspect of the disclosure can be related to a method for cleaning oven 10 and can include moving broiler element 24 within the interior cavity 14 of the oven 10. As discussed above, the interior cavity 14 is defined by an interior liner 12 including two generally parallel, spaced-apart side walls 16 and 18, a top wall 20 extending between the two side walls 16 and 18, and back wall 22 extending downwardly from the top wall 20. The broiler element 24 is moved from the above-described cooking position P1, wherein the broiler element 24 extends laterally along the top wall 20 in a direction D1 between the two side walls 16 and 18 and longitudinally L away from the back wall 22, to a cleaning position P2, wherein the broiler element 24 extends laterally along the back wall 22 in the direction D1 between the two side walls 16 and 18 and vertically V away from the top wall 20. The method further includes causing heating of the broiler element 24 and a cleaning mode including operating the broiler element for pyrolytic cleaning of the back wall 22 for less than 2.5 hours.
The method can further include removing first and second side panel inserts 40 and 42 from the oven cavity 14. As discussed above, the first and second side panel inserts 40 and 42 are initially positioned within the oven cavity 14 respectively adjacent one of each of the two side walls 16 and 18 and beneath the shield 28. The broiler assembly 26 can further include the retention pin 46 engaging a portion of the interior liner 12 to maintain the broiler assembly 26 in the cooking position P1 against the force of gravity. In this respect, moving the broiler element 24 (i.e., with the broiler assembly 26) between the cooking position P1 and the cleaning position P2 includes releasing the retention pin 46 from the portion of the interior liner 12 (e.g., hole 54) to allow movement of the broiler assembly 26 into the cleaning position P2.
