Description:
FIELD OF THE DISCLOSURE 
     The present disclosure relates to a cooking assembly. More particularly the present disclosure relates to a built-in oven and cooktop cooking assembly for recreational vehicle applications. 
     BACKGROUND OF THE DISCLOSURE 
     The recreational vehicle (RV) market has been growing in recent years. Increasingly, consumers want to retain the conveniences and luxuries of home while away from home. In particular, consumers are demanding more luxuries and aesthetic appeal in the kitchen. 
     Cooking appliances such as ovens and cooktops for use in the recreational vehicle industry are subject to numerous regulations. Such regulations impact design specifications of ovens such as but not limited to the location of air inlet ports and air outlet ports. For example, Article 1.21.3 of the American National Standard For Recreational Vehicle Cooking Gas Appliances states: “Vent openings and flue deflectors shall not be located on a front vertical surface below the 36 in (914 mm) level.” Additionally, these regulations also can constrain the size of such appliances. Therefore, maximizing the size of the cooking appliances while maintaining compliance with the regulations in the recreation vehicle industry is a constant goal of manufacturers.

In some embodiments, height  64  is about 20.3 inches. In some embodiments, first cutout  18  has a width  52  which may be as little as 22 inches, 22.5 inches, 23 inches, as great as 24 inches, 24.5 inches, 25 inches, or within any range defined between any two of the foregoing values. In some embodiments, width  52  is about 23.5 inches. 
     As shown in  FIG. 2 , first cutout  18  spans a portion of front surface  16  and is spaced from top surface  12 , bottom surface  19 , back surface  17 , and side surfaces  14 . Top edge  18   c  of first cutout  18  is spaced from top surface  12  by a distance  62 . Suitable distances  62  include values that may be as little as 1 inch, 2 inches, 4 inches, as great as 6 inches, 7 inches, 8 inches, or within any range defined between any two of the foregoing values. In an exemplary embodiment, distance  62  is 4 inches. Side surfaces  18   b ,  18   c  of cutout  18  are also spaced from side surfaces  14  by distances  68   a  and  68   b , respectively, as measured on both edges of cutout  18  as shown in  FIG. 2 . Distances  68  vary depending on the configuration of cabinet  13  and countertop  11  of housing  10  within the context of a kitchen area. Distances  68  may be as little as 2 inches, 3 inches, 4 inches, as great as 6 inches, 7 inches, 8 inches, or within any range defined between any two of the foregoing values. In one embodiment, distances  68  may have the same value of at least 2 inches. In other embodiments, distances  68   a  and  68   b  may be different. 
     Second cutout  20  is configured to receive cooktop  40  and vent assembly  30  as described further below and is formed in the top surface  12  of housing  10  extending towards bottom surface  19 . Second cutout  20  is defined by first and second side edges  20   b ,  20   c , front edge  20   d , and back edge  20   a . First and second edges  20   b  and  20   c  may be parallel or substantially parallel and front edge  20   d  and back edge  20   a  may be parallel or substantially parallel. Further, first and second edges  20   b  and  20   c  may be perpendicular or substantially perpendicular to front edge  20   d  and back edge  20   a.    
     Second cutout  20  has a height  72  which may be as little as 23 inches, 23.5 inches, 24 inches, as great as 25 inches, 25.5 inches, 26 inches, or within any range defined between any two of the foregoing values. As shown in  FIG. 2 , height  72  of second cutout  20  intersects a portion of the interior defined by first cutout  18 . As such, in an exemplary embodiment, height  72  of second cutout  20  may be the sum of height  64  and distance  62 . Second cutout  20  has a width  54  defined between first edge  20   b  and second edge  20   c . In some embodiments, width  54  may be as little as 22 inches, 22.5 inches, 23 inches, as great as 24 inches, 24.5 inches, 25 inches, or within any range defined between any two of the foregoing values. Cutout  20  spans a distance  56  along top surface  12  defined between front edge  20   d  and back edge  20   a . In some embodiments, distance  56  may be as little as 15 inches, 15.5 inches, 16 inches, as great as 17 inches, 17.5 inches, 18 inches, or within any range defined between any two of the foregoing values. For example, width  54  may be 23.5 inches. In some embodiments, first cutout  18  and second cutout  20  have equal or substantially equal widths, i.e. width  54  and width  52  are equal or substantially equal to one another. In some embodiments, first edge  20   b  of second cutout  20  may be aligned or substantially aligned with second edge  18   b  of the first cutout  18 . Similarly, second edge  20   c  of second cutout  20  may be aligned or substantially aligned with first edge  18   a  of the first cutout  18 . In some embodiments, distance  56  is 16.75 inches. 
     Second cutout  20  spans a portion of top surface  12  and is spaced from back surface  17 , front surface  16 , bottom surface  19 , and side surfaces  14 . First edge  20   d  of second cutout  20  is spaced from front surface  16  by a distance  70  that may be as little as 1 inch, 1.25 inches, 1.5 inches, as great as 1.75 inches, 1.85 inches, 2 inches, or within any range defined between any two of the foregoing values. In some embodiments, distance  70  is 1.625 inches. Side edges of  20   b ,  20   c  of cutout  20  are also spaced from side surfaces  14  by distances  68   a  and  68   b  as measured from edges  20   b ,  20   c  as shown in  FIG. 2 . Distances  68   a  and  68   b  may be as little as 2 inches, 3 inches, 4 inches, as great as 6 inches, 7 inches, 8 inches, or within any range defined between any two of the foregoing values. In some embodiments, distances  68   a  and  68   b  may be equal and may be, for example, at least 2 inches. However, it is contemplated that, in alternate embodiments, distances  68   a  and  68   b  be different from one another. Finally, back edge  20   a  of second cutout  20  is spaced from back surface  17  by a distance  60  that may be as little as 2 inches, 3 inches, 4 inches, as great as 6 inches, 7 inches, 8 inches, or within any range defined between any two of the foregoing values. In an exemplary embodiment, distance  60  is at least 2 inches. 
     Housing  10  with first cutout  18  and second cutout  20  defines a space having a depth  58  for accommodating oven  22  and cooktop  40 . Depth  58  may be as little as 17 inches, 17.5 inches, 18 inches, as great as 19 inches, 19.5 inches, 20 inches, or within any range defined between any two of the foregoing values. In some embodiments, depth  58  is about 18.4 inches. Back edge  20   a  is spaced apart from back surface  17  by a distance  60 . In some embodiments, distance  60  may be as little as 2 inches, 3 inches, 4 inches, as great as 6 inches, 7 inches, 8 inches, or within any range defined between any two of the foregoing values. In some embodiments, distance  60  is at least 2 inches. 
     As mentioned earlier, first cutout  18  is sized and shaped to receive oven  22  as shown in  FIG. 1 . Referring now to  FIGS. 1, 3 and 8 , oven  22  includes a front panel  38 , a top panel  24 , back panel  46 , bottom panel  39 , and first and second side panels  28   a  and  28   b  (referred to collectively as side panels  28 ) to define oven enclosure  50 . As shown, front panel  38  includes an oven door  26  pivotably connected to oven  22 . Opening oven door  26  allows a user to access oven enclosure  50 . Side panels  28  include indentations  23  that are configured to allow a user fit their hand within indentations  23  for the purposes of lifting and/or moving oven  22 . For example, indentations  23  may have a suitable size and shape for a human hand. An air inlet  48  may be formed along the bottom surface of the oven  22  and may be defined between the front panel  38  and the bottom panel  39 . In use, oven enclosure  50  is in fluid communication with air inlet  48 . 
       FIG. 9  is a cross-sectional view of oven  22  taken along line  9 - 9  in  FIG. 8 . As shown in  FIG. 9 , burner  42 , plates  31  and  35 , and shelves  44  are positioned within oven enclosure  50 . In some embodiments, plates  31  and  35  are metal plates. Burner  42  is positioned below shelves  44  within oven enclosure  50 . During use, burner  42  heats air within oven enclosure  50 . To provide heat, burner  42  is connected to an energy source  45 , such as propane or natural gas, by a conduit or pipe. In some embodiments, burner  42  can be connected to dials  25  on front panel  38 . For example, dials  25  may be used to control the amount of heat applied (i.e., the temperature within oven  22 ). 
     Plates  31  and  35  are coupled to one another and positioned between shelves  44  and burner  42 . Plate  31  is positioned closer to burner  42  than plate  35  and may include a plurality of apertures (not shown) to permit air to flow through plate  31 . Plate  35  is removable and is positioned above plate  31  and may may block air flow through the center portion of the oven, directing air flow towards the walls of oven enclosure  50  and towards air outlet  49 . In some embodiments, plate  35  may be removed from oven enclosure  50  such that heated air only moves through the apertures of plate  31  as the air ascends within oven enclosure  50 . 
       FIG. 10  is a cross-sectional diagram of the oven  22  taken along line  10 - 10  of  FIG. 8  and illustrates the flow of air within oven enclosure  50 . As shown, air enters oven  22  through the air inlet  48  in the direction of arrow  51 . As air absorbs heat generated by burner  42 , the heated air begins to rise and moves in the direction of arrow  53  through the holes of metal plate  31  due to natural convection. As the air continues to rise along arrow  53 , a portion of the heat is transferred to shelves  44  and the content that may be resting on shelves  44  (e.g., food items). The heated air then exits the oven  22  through air outlet  49  and vent assembly  30  in the direction of arrow  55 . 
     As shown in at least  FIG. 3 , top panel  24  of oven  22  includes a plurality of apertures  36  that are positioned along the surface of top panel  24 . Apertures  36  are positioned above electronic components within oven  22  and serve to dissipate heat generated from the electronic components. As mentioned earlier, top panel  24  also includes air outlet  49   
     As also shown in  FIG. 3 , vent assembly  30  includes a vent  32  and a vent cover  34 . Vent  32  provides an extension of air outlet  49  ( FIG. 10 ) by a conduit  33 , which couples vent  32  to oven  22  at air outlet  49 . Conduit  33  is in fluid communication with oven enclosure  50  and provides a pathway for air to flow upward from oven enclosure  50  through vent assembly  30 . As such, air exiting oven enclosure  50  will move through air outlet  49  and conduit  33  toward vent cover  34  to exit oven  22 . 
     Vent cover  34  is coupled to vent  21  along the top surface of vent  32  and includes apertures  37 . Vent cover  34  serves to distribute exiting air from oven  22 . When heated air moves through conduit  33  of vent  32 , vent cover  34  allows some of the heated air to continue moving vertically along arrow  61  through vent cover  34  without significantly changing its flow path. However, a portion of the heated air is unable to flow along this path due to the small size of apertures  37  along this flow path. As such, vent cover  34  funnels the remaining heated air outwards towards the edges of vent  32  and vent cover  34  such that the heated air can exit oven  22  through the apertures  37  provided on this part of vent cover  34  as indicated by arrow  63 . 
     Vent cover  34  also prevents external debris from entering oven  22  due to the relatively small size of apertures  37 . In an alternate embodiment, vent assembly  30  is made of a single piece where vent  32  and vent cover  34  are integrally formed. 
     Cooking assembly  100  includes a cooktop  40 . When cooking assembly  100  is assembled, cooktop  40  is inserted into second cutout  20  ( FIG. 7 ), is coupled to oven  22  along top panel  24 , and is spaced apart from back surface of housing  10 . Furthermore, when coupling cooktop  40  onto oven  22  along top panel  24 , connector  67  on cooktop  40  couples to front panel  38  (e.g., connector  67  of cooktop  40  couples to connector  71  ( FIG. 10 ) protruding from front panel  38 ) such that dials  25  on the front panel  38  can control the settings of cook top  40  (e.g., flowrate of gas to control the flame height). Cooktop  40  spans the exposed area of top panel  24  within second cutout  20  such that no gap exists between top surface  12  of housing  10  and cooktop  40 . In some embodiments, the upper surface of cooktop  40  is substantially flush with top surface  12 . 
       FIGS. 4-7  illustrate a method of assembling cooking assembly  100 . First, housing  10  is cut to form a first cutout  18  in front surface  16  and a second cutout  20  is formed in top surface  12 . As illustrated in  FIG. 4 , oven  22  is inserted into first cutout  18  of housing  10  in the direction of arrow  74  until front panel  38  and oven door  26  protrudes from front surface  16 . Oven  22  can be coupled to housing  10 . In some embodiments, oven  22  is coupled to housing  10  by a plurality of screws. However, it is contemplated that, in alternate embodiments, alternate fastening means may be used such as fasteners or couplers. After oven  22  is inserted into first cutout  18 , oven  22  is connected to an energy source  45  and a power source  47  by a conduit such as a pipe or cord. In some embodiments, the power source is a 12V power source. Power source  47  provides electricity to cooking assembly  100  such that oven  22  and cooktop  40  perform a function when a user actuates one of dials  25 . Energy source  45  provides an energy source, such as natural gas or propane, to cooktop  40  and oven  22  such that cooktop  40  and oven  22  provide heat for example to cook or bake foodstuff. 
     After oven  22  is inserted into first cutout  18  and connected to the energy source  45  and power source  47 , vent  32  of vent assembly  30  is inserted into second cutout  20  in the direction of arrow  76  such that vent  32  is coupled to oven  22  as shown in  FIG. 5 . Conduit  33  connects to oven  22  to form a fluid path for the air from the interior of the oven  22  through the vent  32 . In one embodiment, vent  32  is coupled to oven  22  at air outlet  49  by a pair of screws  41 . However, it is contemplated that, in alternate embodiments, alternate fastening means may be used such as fasteners, couplers, etc. 
     After inserting vent  32 , vent cover  34  is coupled to vent  32  as shown by arrow  78  in  FIG. 5 . In some embodiments, vent cover  34  is coupled to vent  32  by a pair of screws  43 . However, it is contemplated that, in alternate embodiments, alternate fastening means may be used such as fasteners, couplers, etc. 
     After mounting vent cover  34  onto vent  32 , cooktop  40  is connected to the energy source  45  as shown in  FIG. 7 . In one embodiment, cooktop  40  is also connected to a power source  47 . In a further alternate embodiment, the power source is a 1.5V power source. Cooktop  40  is then inserted into second cutout  20  and coupled to the top panel  24  of oven  22  in the direction of arrow  80 . In one embodiment, cooktop  40  is coupled to oven  22  by a plurality of screws. However, it is contemplated that, in alternate embodiments, alternate fastening means may be used such as fasteners or couplers. In some embodiments, cooktop  40  has the same or substantially the same width as oven  22 . When installed, cooktop  40  is spaced apart from front surface  16 , back surface  17 , and side surfaces  14 . 
     In the fully assembled configuration, oven  22  fits within first cutout  18  of housing  10 , and the front panel  38  is substantially flush with front surface  16 . Alternatively, the front panel  38  may protrude from the front surface  16 . In some embodiments, the housing  10  may be positioned on a substrate, such as a floor, such that bottom surface  19  of housing  10  is on the substrate. When installed, housing  10  surrounds the front panel  38  of oven  22 . For example, housing  10  is positioned below oven  22  between the floor and the oven  22  and above oven  22 . Because oven  22  is positioned within first cutout  18 , which does not extend to the floor, the front surface  16  of housing  10  maintains a flowing appearance below the oven  22 . Additionally, because first cutout  18  does not extend to top surface  12 , the front surface  16  of housing  10  maintains a flowing appearance above the oven. In contrast, typical slide-in oven models require a break or cutout to be formed in the kitchen cabinet from the top surface of the cabinet to the floor to enable the oven to be fit into a defined space extending the height of the cabinets. This design creates breaks in the cabinets and has less visual appeal. 
     Similarly, cooktop  40  may fit within second cutout  20  of housing  10  such that cooktop  40  is substantially flush with the top surface  12  of housing  10 . Alternatively, cooktop  40  may protrude from the top surface  12  of housing  10 . When cooktop  40  is installed, housing  10  surrounds the cooktop  40  on four sides. Because cooktop  40  does not extend fully from the front surface  16  to the back surface  17  (i.e., cooktop  40  does not adjoin or intersect front surface  16  or back surface  17 ), top surface  12  has a flowing appearance. In contrast, the top surface  12  would have a less flowing appearance if the cooktop  40  extended to front surface  16  at least because top surface  12  having distance  70  would be eliminated. 
     Moreover, in some embodiments when vent assembly  30  is coupled to oven  22  within housing  10 , vent cover  34  is substantially flush with the top surface  12  of housing  10 . In other words, the top surface of the vent cover  34  is in the same horizontal plane as top surface  12  of cooktop  40 . Alternatively, vent cover  34  may protrude from the top surface  12  of housing  10 . When vent cover  34  is installed, housing  10  surrounds vent cover  34  on four sides. Because vent cover  34  is positioned within second cutout  20  and does not extend fully from back surface  17  to front surface  16  (i.e., vent cover  34  does not adjoin or intersect back surface  17  of front surface  16 ), top surface  12  has a flowing appearance. 
     Having a two-part cooking assembly  100  comprised of a separate oven  22  and cooktop  40  provides for easier installation as each component is inserted and connected to their respective power and gas sources as appropriate. It also provides for easy removal of components of cooking assembly  100  such as cooktop  40 . For example, for the removal of cooktop  40 , a user would need to decouple cooktop  40  from oven  22 , disconnect cooktop  40  from power source  47  and energy source  45 , and pull cooktop  40  out of second cutout  20  for proper removal. Additionally, the two-part assembly provides flexibility to the consumer as a consumer has the choice of selecting from different types of ovens  22  and different types of cooktops  40  for cooking assembly  100  and is only constrained by the spatial limitations of first cutout  18  and second cutout  20  in housing  10 . Furthermore, in recreational vehicles, there are regulations regarding the location of vent openings based on the size of the ovens. Because cooktop  40  and oven  22  are separated, oven  22  can be of a greater size since the size of cooktop  40  is not considered when complying with recreational vehicle regulations.
