Definitions
- the present invention relates to an oven door including an exterior panel formed of plastic.
- An oven door includes an interior panel for sealing a heating chamber of the oven and an exterior panel spaced from the interior panel to provide a layer of insulation, e.g., solid and/or air, between the interior panel and the exterior panel.
- the exterior panel also aesthetically covers the interior panel.
- the exterior panel is typically formed of several metal components that are separately formed and subsequently assembled together.
- the exterior panel also typically includes a glass pane for viewing the heating chamber of the oven.
- the material cost for manufacturing the metal components and the glass pane is relatively high.
- relatively high manufacturing costs are associated with forming the components and the glass panel separately and subsequently assembling the components and the glass panel.
- the exterior panel can be formed of stainless steel to provide this appearance; however, stainless steel is a relatively expensive material thereby increasing the cost to manufacture exterior panels formed of stainless steel.
- the exterior panel can also be formed of another type of metal and subsequently painted to either have a stainless steel appearance or to have another color desired by the consumer.
- Such paint adds cost not only for the paint itself but also for manufacturing costs associated with applying the paint to the exterior panel. The paint is also subject to scratching, chipping, cracking, etc.
- a handle is connected to the exterior panel and extends away from the exterior panel for moving the oven door between open and closed positions.
- the handle typically includes a flat surface that abuts a flat surface of the exterior panel.
- a threaded fastener extends through the flat surface of the handle and the flat surface of the exterior panel to affix the handle to the exterior panel.
- an oven door having an exterior panel having lower material and assembly costs and having a color desired by consumers.
- an oven door having a handle that reliably connects to the exterior panel and has an aesthetic appearance.
- the present invention includes an oven door for closing an opening to a heating chamber of an oven.
- the oven door comprises an interior panel for facing the heating chamber.
- the interior panel has a glass sheet for viewing the heating chamber.
- An exterior panel is affixed to the interior panel for facing away from the heating chamber and includes a frame portion formed of plastic defining an aperture aligned with the glass sheet for viewing the heating chamber.
- a non-opaque panel is fixed relative to the frame portion and extends across the aperture and has an inside surface facing the interior panel.
- the exterior panel has a masking portion formed of plastic and integrally formed with the frame portion and extending from the frame portion into the aperture along the inside surface of the non-opaque panel and defining a window for viewing the heating chamber through the glass sheet.
- the present invention also includes an oven door for closing an opening to a heating chamber of an oven.
- the oven door comprises an interior panel for facing the heating chamber and an exterior panel formed of plastic and having an exterior side for facing away from the heating chamber.
- the exterior panel presents a pocket defined by a wall extending from the exterior side toward the interior panel and a bottom extending transversely from the wall spaced from the exterior side.
- a handle has a boss portion extending into the pocket for stabilizing the handle relative to the exterior panel and a gripping portion extending from the boss portion away from the exterior panel for moving the oven door between open and closed positions.
- the bottom is disposed between the boss portion of the handle and the interior panel.
- the handle has a post extending from the gripping portion through the boss portion and being connected to the interior panel for coupling the interior panel, the exterior panel, and the handle.
- the frame portion of the exterior panel By forming the frame portion of the exterior panel from plastic, the costs associated with material and manufacturing of the frame portion is advantageously decreased.
- the manufacturing process of forming the frame portion is more efficient, and thus less costly, by decreasing or eliminating secondary assembly steps.
- Forming the exterior from plastic also allows the designer more styling freedom because plastic is relatively easy to form into intricate shapes.
- the plastic of the exterior panel also provides superior insulation to reduce the amount of heat that is transferred to the an exterior side of the exterior panel.
- the plastic of the frame portion can be advantageously colored. Further, since the plastic is colored, as opposed to being painted, desired coloring of the frame portion is accomplished without secondary steps such as painting, thereby advantageously making the manufacturing process of the exterior panel more efficient and less costly. In addition, since the plastic itself is colored, the coloring is more durable than paint.
- the interaction between the handle and the exterior panel advantageously increases the stability and durability of the oven door.
- the exterior panel firmly retains the handle to increase the stability of the handle relative to the exterior panel.
- the bottom is disposed between the boss portion and the handle and since the post extends from the handle, the bottom of the exterior panel is retained between the handle and the interior panel when the post is connected to the interior panel.
- the interior panel, the exterior panel, and the handle are coupled together when the post is connected to the interior panel.

Description
- The subject patent application claims priority to and all the benefits of U.S. Provisional Patent Application No. 61/371,074 which was filed on Aug. 5, 2010, the entire specification of which is expressly incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to an oven door including an exterior panel formed of plastic.
- 2. Description of the Related Art
- An oven door includes an interior panel for sealing a heating chamber of the oven and an exterior panel spaced from the interior panel to provide a layer of insulation, e.g., solid and/or air, between the interior panel and the exterior panel. The exterior panel also aesthetically covers the interior panel.
- The exterior panel is typically formed of several metal components that are separately formed and subsequently assembled together. The exterior panel also typically includes a glass pane for viewing the heating chamber of the oven. The material cost for manufacturing the metal components and the glass pane is relatively high. In addition, relatively high manufacturing costs are associated with forming the components and the glass panel separately and subsequently assembling the components and the glass panel.
- Also, some consumers desire ovens having different colors. As one example, some consumers desire stainless steel ovens and are willing to pay higher prices for an oven that has a stainless steel appearance. As such, the exterior panel can be formed of stainless steel to provide this appearance; however, stainless steel is a relatively expensive material thereby increasing the cost to manufacture exterior panels formed of stainless steel. The exterior panel can also be formed of another type of metal and subsequently painted to either have a stainless steel appearance or to have another color desired by the consumer. Such paint adds cost not only for the paint itself but also for manufacturing costs associated with applying the paint to the exterior panel. The paint is also subject to scratching, chipping, cracking, etc.
- In addition, a handle is connected to the exterior panel and extends away from the exterior panel for moving the oven door between open and closed positions. The handle typically includes a flat surface that abuts a flat surface of the exterior panel. A threaded fastener extends through the flat surface of the handle and the flat surface of the exterior panel to affix the handle to the exterior panel. As the handle is used over time, the interface between the abutting flat surfaces of the handle and the exterior panel begins to loosen such that the handle wobbles relative to the exterior panel. Such an occurrence gives an unwanted feel and appearance of low quality.
- Accordingly, there remains opportunity to manufacture an oven door having an exterior panel having lower material and assembly costs and having a color desired by consumers. There also remains opportunity to manufacture an oven door having a handle that reliably connects to the exterior panel and has an aesthetic appearance.
- The present invention includes an oven door for closing an opening to a heating chamber of an oven. The oven door comprises an interior panel for facing the heating chamber. The interior panel has a glass sheet for viewing the heating chamber. An exterior panel is affixed to the interior panel for facing away from the heating chamber and includes a frame portion formed of plastic defining an aperture aligned with the glass sheet for viewing the heating chamber. A non-opaque panel is fixed relative to the frame portion and extends across the aperture and has an inside surface facing the interior panel. The exterior panel has a masking portion formed of plastic and integrally formed with the frame portion and extending from the frame portion into the aperture along the inside surface of the non-opaque panel and defining a window for viewing the heating chamber through the glass sheet.
- The present invention also includes an oven door for closing an opening to a heating chamber of an oven. The oven door comprises an interior panel for facing the heating chamber and an exterior panel formed of plastic and having an exterior side for facing away from the heating chamber. The exterior panel presents a pocket defined by a wall extending from the exterior side toward the interior panel and a bottom extending transversely from the wall spaced from the exterior side. A handle has a boss portion extending into the pocket for stabilizing the handle relative to the exterior panel and a gripping portion extending from the boss portion away from the exterior panel for moving the oven door between open and closed positions. The bottom is disposed between the boss portion of the handle and the interior panel. The handle has a post extending from the gripping portion through the boss portion and being connected to the interior panel for coupling the interior panel, the exterior panel, and the handle.
- By forming the frame portion of the exterior panel from plastic, the costs associated with material and manufacturing of the frame portion is advantageously decreased. The manufacturing process of forming the frame portion is more efficient, and thus less costly, by decreasing or eliminating secondary assembly steps. Forming the exterior from plastic also allows the designer more styling freedom because plastic is relatively easy to form into intricate shapes. The plastic of the exterior panel also provides superior insulation to reduce the amount of heat that is transferred to the an exterior side of the exterior panel.
- In addition, the plastic of the frame portion can be advantageously colored. Further, since the plastic is colored, as opposed to being painted, desired coloring of the frame portion is accomplished without secondary steps such as painting, thereby advantageously making the manufacturing process of the exterior panel more efficient and less costly. In addition, since the plastic itself is colored, the coloring is more durable than paint.
- Finally, the interaction between the handle and the exterior panel advantageously increases the stability and durability of the oven door. By receiving the boss portion in the pocket, the exterior panel firmly retains the handle to increase the stability of the handle relative to the exterior panel. Also, since the bottom is disposed between the boss portion and the handle and since the post extends from the handle, the bottom of the exterior panel is retained between the handle and the interior panel when the post is connected to the interior panel. As such, the interior panel, the exterior panel, and the handle are coupled together when the post is connected to the interior panel.

Specifically, theexterior panel 20 has anexterior side 28 that faces outwardly relative to the rest of theoven 10 and has an aesthetically pleasing appearance. Theexterior panel 20 includes aframe portion 30 defining anaperture 32 aligned with theglass sheet 26 of theinterior panel 18 for viewing theheating chamber 12. Theframe portion 30 typically has a one-piece construction.Insulation 34, such as that shown inFIG. 5 , can be disposed between theframe portion 30 of theexterior panel 20 and theinterior panel 18. - The
exterior panel 20 can define agroove 36 and theinterior panel 18 can define aflange 38 that extends into thegroove 36 to couple theexterior panel 20 and theinterior panel 18. In the alternative, or in addition, other complementary features and/or fastener 70 s (not shown) can also attach theexterior panel 20 and theinterior panel 18 to each other. - At least a portion of the
exterior panel 20, including theframe portion 30, can be formed of plastic such as a polyester. The plastic can be glass filled or can be free of glass filling. One example of a type of suitable polyester is glass filled thermoplastic polyester commercially available from BASF Corporation in Florham Park, N.J. under the tradename Ultramid® B4040G3. However, it should be appreciated that theexterior panel 20 can be formed of any type of suitable material without departing from the nature of the present invention. The plastic of theexterior panel 20 can have any color. As one example, the plastic of theexterior panel 20 can simulate the look of metal such as stainless steel. - The
non-opaque panel 22 is fixed relative to theframe portion 30 and extends across theaperture 32 defined by theframe portion 30. Thenon-opaque panel 22 has aninside surface 40 facing theinterior panel 18. Thenon-opaque panel 22 can be, for example, transparent, speckled, screened, translucent, frosted, etc. - As set forth further below, the
exterior panel 20 and/or thenon-opaque panel 22 can be formed and/or combined by plastic injection molding. A plastic injection mold (not shown) is used for the plastic injection molding and, specifically, receives molten plastic to shape the molten plastic. However, it should be appreciated that theexterior panel 20 and/or thenon-opaque panel 22 can be formed in any way without departing from the nature of the present invention. - The
first oven door 14 typically includes avent portion 42 for venting heated air from between theinterior panel 18 and theexterior panel 20. Thevent portion 42 is typically formed of the same type of material as theframe portion 30 and is typically integrally formed with theframe portion 30 of theexterior panel 20, i.e., formed together simultaneously or at substantially the same time so as to form a single part. Alternatively, thevent portion 42 can be formed separately from theframe portion 30 and subsequently attached to theframe portion 30. Thevent portion 42 can be blended with theframe portion 30 so that thevent portion 42 and theframe portion 30 have a common surface appearance. Alternatively, thevent portion 42 and theframe portion 30 can have different surface texture and/or color. - In the first embodiment of the
first oven door 14, with reference toFIGS. 2 and 3 , theexterior panel 20 has a maskingportion 44 typically formed of plastic. The maskingportion 44 is typically integrally formed with theframe portion 30 as shown inFIGS. 2 and 3 , i.e., formed together simultaneously or at substantially the same time so as to form a single part. Alternatively, the maskingportion 44 is integrally formed with thenon-opaque panel 22 such that the maskingportion 44 and thenon-opaque panel 22 in combination are assembled to theframe portion 30 in theaperture 32. In any event, the maskingportion 44 extends from theframe portion 30 into theaperture 32 along theinside surface 40 of thenon-opaque panel 22 and defines awindow 46 for viewing theheating chamber 12 through the glass sheet of theinterior panel 18. - The masking
portion 44 is typically formed of the same type of plastic as the rest of theexterior panel 20 as set forth above. However, it should be appreciated that the maskingportion 44 can be formed of any type of suitable material without departing from the nature of the present invention. The plastic of the maskingportion 44 can have any color and typically has a different color than the plastic of theframe portion 30. As one example, the color of the plastic of the maskingportion 44 is black. Alternatively, the color of the plastic of the maskingportion 44 can be the same as the color of the plastic of theframe portion 30. - With continued reference to
FIGS. 2 and 3 ,non-opaque panel 22 is formed separately from theexterior panel 20 and theexterior panel 20 supports thenon-opaque panel 22. Thenon-opaque panel 22 can be fixed to the maskingportion 44 of theexterior panel 20. As one example, thenon-opaque panel 22 can be adhered to the maskingportion 44. For example, thenon-opaque panel 22 can be adhered to the maskingportion 44 with an adhesive; however, it should be appreciated that thenon-opaque panel 22 can be adhered to the maskingportion 44 with any type of adhesive without departing from the nature of the present invention. In the alternative to adhering, thenon-opaque panel 22 can be, for example, overmolded, fastened, mechanically retained, etc., to the maskingportion 44 and/or the rest of theexterior panel 20. - The masking
portion 44 is typically recessed relative to theframe portion 30, as best shown inFIG. 2 , so that thenon-opaque panel 22 is flush with theframe portion 30 along theexterior side 28 when supported by theexterior panel 20, as shown inFIG. 1 . In other words, the maskingportion 44 defines arecess 48 that receives thenon-opaque panel 22. Alternatively, the maskingportion 44 is positioned relative to theframe portion 30 such that thenon-opaque panel 22 is not flush, i.e., is stepped, with theframe portion 30 along theexterior side 28 when supported by theexterior panel 20. - In the first embodiment of the
first oven door 14, thenon-opaque panel 22 is typically formed of glass. Alternatively, thenon-opaque panel 22 is formed of plastic. When formed of plastic, for example, thenon-opaque panel 22 can be glass filled or can be free of glass filling. As one example, thenon-opaque panel 22 can be formed from an unfilled polyethersufone commercially available from BASF Corporation in Florham Park, NJ under the tradename Ultrason® E2010. In the configuration where thenon-opaque panel 22 is formed of plastic, thenon-opaque panel 22 can be fixed to the maskingportion 44 by, for example fusing, welding, overmolding, etc., in addition to the fixing configurations set forth above. - With continued reference to the first embodiment of the
first oven door 14, theframe portion 30 and the maskingportion 44 of theexterior panel 20 are typically simultaneously formed in the injection mold. For example, one shot of molten plastic can be injected into the injection mold to form theframe portion 30 and the maskingportion 44, i.e., theframe portion 30 and the maskingportion 44 are integrally formed of a single type of plastic have a single color and surface texture. - Alternatively, for example, a first shot of molten plastic can be injected into the injection mold to form the
frame portion 30 and a second shot of molten plastic can be injected into the injection mold to form the maskingportion 44. In such a configuration, the first shot and the second shot can include plastic of different type, color, and/or surface texture, i.e., the resultingframe portion 30 and maskingportion 44 can have different plastic type, color, and/or texture. Alternatively, as set forth above, the maskingportion 44 and thenon-opaque panel 22 can be integrally formed and subsequently assembled to theframe portion 30, in which case the framenon-opaque panel 22 and the maskingportion 44 can be formed by a first shot and a second shot, respectively, of molten plastic. In any event, it should be appreciated that the injection mold can receive more than two shots with the additional shots forming additional features. As one example, thevent portion 42 can be formed by a third shot so that thevent portion 42 and theframe portion 30 can include have different plastic type, color, and/or surface texture. - Regardless of whether the
frame portion 30 and the maskingportion 44 are formed from one or two shots of molten plastic, thenon-opaque panel 22 can be subsequently attached to theframe portion 30 and/or the maskingportion 44 after formation of theframe portion 30 and maskingportion 44 in the injection mold, e.g., after theexterior panel 20 is removed from the injection mold. Alternatively, thenon-opaque panel 22 can be inserted into the injection mold before the molten plastic is injected such that, upon injection into the injection mold, the molten plastic partially encapsulates thenon-opaque panel 22, i.e., thenon-opaque panel 22 is overmolded by the molten plastic of theexterior panel 20 in the injection mold. Specifically, in the scenario where a single shot forms theexterior panel 20, the single shot partially encapsulates thenon-opaque panel 22. In the scenario where a first shot and a second shot form theexterior panel 20, the first and/or the second shot partially encapsulates thenon-opaque panel 22. - With reference to
FIG. 4 , in the second embodiment of thefirst oven door 14, thenon-opaque panel 22 is integrally formed with theexterior panel 20, i.e., formed together simultaneously or at substantially the same time so as to form a single part. Thenon-opaque panel 22 is typically formed of plastic. Thenon-opaque panel 22 can be formed from the same type of plastic as that of theexterior panel 20 or can be formed from a different type of plastic than that of theexterior panel 20. The plastic can be glass filled or can be free of glass filling. One example of a type of suitable plastic for thenon-opaque panel 22 is an unfilled polyethersufone commercially available from BASF Corporation in Florham Park, NJ under the tradename Ultrason® E2010. However, it should be appreciated that thenon-opaque panel 22 can be formed of any type of suitable material without departing from the nature of the present invention. - In the second embodiment of the
first oven door 14, the maskingportion 44 can be formed of plastic and integrally formed with theframe portion 30 of theexterior panel 20 and/or thenon-opaque panel 22. In such a configuration, the maskingportion 44 is typically formed of the same type of plastic as the rest of theexterior panel 20 as set forth above. However, it should be appreciated that the maskingportion 44 can be formed of any type of suitable material without departing from the nature of the present invention. The plastic of the maskingportion 44 can have any color and typically has a different color than the plastic of theframe portion 30. Alternatively, the color of the plastic of the maskingportion 44 can be the same as the color of the plastic of theframe portion 30. As one example, the color of the plastic of the maskingportion 44 is black. - When formed of plastic and integrally formed with the
frame portion 30 and/or thenon-opaque panel 22, the maskingportion 44 can extend along insidesurface 40 of thenon-opaque panel 22. In the alternative to being integrally formed with theframe portion 30 and/or thenon-opaque panel 22, the maskingportion 44 can be formed separately from and subsequently combined with theexterior panel 20 and thenon-opaque panel 22. In such a configuration, the maskingportion 44 can be, for example, plastic, metal, a decal, etc. The maskingportion 44 of such a configuration can be partially or fully encapsulated by theframe portion 30 and/or thenon-opaque panel 22 during formation of theframe portion 30 and/or thenon-opaque panel 22 or can be attached or adhered to theframe portion 30 and/or thenon-opaque panel 22. - In the second embodiment of the
first oven door 14, theframe portion 30 and thenon-opaque panel 22 are typically simultaneously formed in the injection mold. For example, a first shot of molten plastic can be injected into the injection mold to form theframe portion 30 and a second shot of molten plastic can be injected into the injection mold to form thenon-opaque panel 22. In such a configuration, the first shot and the second shot can include plastic of different type, color, and/or surface texture, i.e., the resultingframe portion 30 andnon-opaque panel 22 can have different plastic type, color, and/or surface texture. - The first shot of molten plastic forming the
frame portion 30 can also integrally form the maskingportion 44 with theframe portion 30. Alternatively, a third shot of molten plastic, in addition to the first shot for theframe portion 30 and the second shot for thenon-opaque panel 22, can be injected into the injection mold to integrally form the maskingportion 44 with theframe portion 30 and/or thenon-opaque panel 22. It should be appreciated that the injection mold can receive more than three shots with the additional shots forming additional features. - As set forth above, the masking
portion 44 can alternatively be formed separately from theframe portion 30 and thenon-opaque panel 22. For example, the maskingportion 44 can be subsequently attached to theframe portion 30 and/or thenon-opaque panel 22 after formation of theframe portion 30 andnon-opaque panel 22 in the injection mold, e.g., after theframe portion 30 and thenon-opaque panel 22 are removed from the injection mold. Alternatively, the maskingportion 44 can be inserted into the injection mold before the molten plastic is injected such that, upon injection into the injection mold, the molten plastic partially encapsulates the maskingportion 44, i.e., the maskingportion 44 is overmolded by the molten plastic of theframe portion 30 and/or thenon-opaque panel 22 in the injection mold. - With reference to
