Description
- This application claims the benefit of U.S. Provisional Application No. 61/734,046, filed Dec. 6, 2012, which is incorporated in its entirety herein by reference.
- 1. Field of the Invention
- This application relates generally to kitchen appliances and, more particularly, to induction cooktops.
- 2. Description of Related Art
- Many kitchens lack the amount of countertop surface area desired by residents, who would benefit from additional space usable for preparation of food items, for example. A portion of the already-limited countertop surface area available for food preparation is also occupied by other kitchen necessities such as cooktops on which food can be cooked.
- One such cooktop commonly found in kitchens is an induction cooktop. Induction cooktops conduct a high-frequency current through a heating coil to generate a high-frequency magnetic flux that induces a current in cookware made of a ferromagnetic material. This induced current causes the cookware, and the food contained therein, to be heated. To generate the high-frequency current conducted through the heater coils, however, induction cooktops have utilized bulky circuitry fixed immediately adjacent to each heater coil. Such circuitry rendered induction cooktops to be fixed, permanent installations that consumed valuable countertop space.
- Accordingly, there is a need in the art for an adjustable induction cooktop having an adjustable cooking surface including a heating coil configured to be pivotally or otherwise adjusted relative to a generator board. The adjustable cooking surface can thus be adjusted to expose, and render usable, a countertop or other work surface concealed by the cooking surface while the cooking surface is in a cooking orientation in which cookware is inductively heated as a result of the conduction of electric current through the heating coil.
- According to one aspect, the subject application involves a cooktop assembly including a generator that produces a high-frequency alternating current and is configured to be coupled to a surface of a cabinet. The cooktop assembly further includes an adjustable cooking surface comprising a heating coil electrically connected to the generator to conduct the high-frequency alternating current produced by the generator and induce an induced current in a cooking vessel supported by the movable portion while the movable portion is in a cooking orientation. An adjustable coupling pivotally couples the adjustable cooking surface to the generator and supports the adjustable cooking surface at a plurality of different angular orientations relative to the generator.
- According to another aspect, the subject application involves a cooktop assembly including an adjustable cooking surface with a heating coil that conducts an alternating electric current and induces an induced current in a cooking vessel supported by the adjustable cooking surface to heat the cooking vessel. A hinge pivotally supports the adjustable cooking surface to be pivotally adjusted between a cooking orientation, in which an externally-exposed surface of the adjustable cooking surface is substantially horizontal, and a stowed orientation in which the externally-exposed surface is substantially vertical. A generator is coupled to the hinge to generate and supply the alternating electric current conducted by the heating coil, and a duct is formed within a hinge housing to convey cooling air entering an air inlet generally toward the adjustable cooking surface.
- According to another aspect, the subject application involves a cooktop assembly including a generator that produces a high-frequency alternating current and is configured to be coupled to a surface of a cabinet. An adjustable cooking surface is also provided, and includes a heating coil electrically connected to the generator to conduct the high-frequency alternating current produced by the generator and induce an induced current in a cooking vessel supported by the movable portion while the movable portion is in a cooking orientation. A hinge pivotally couples the adjustable cooking surface to the generator and supports the adjustable cooking surface at a plurality of different angular orientations relative to the generator. An air inlet is formed in at least one of a hinge housing forming a portion of the hinge and a generator housing enclosing at least a portion of the generator to allow for the introduction of cooling air into the cooktop assembly. A duct is formed within the hinge housing to convey cooling air entering the air inlet generally toward the adjustable cooking surface. A damping device coupled to the hinge slows pivotal adjustment of the adjustable cooking surface toward a countertop surface of the cabinet to which the cooktop assembly is to be installed relative to an undamped rate at which the adjustable cooking surface can be pivotally adjusted.

- Referring now to
FIGS. 1-4 , an exemplary embodiment of acooktop assembly 10 is illustrated. Thecooktop assembly 10 may be arranged with respect to acabinet 12 that may be part of a kitchen, for example. Thecabinet 12 includes acountertop 14 and optionallydoors 16 and/ordrawers 18 that provide access tostorage space 20. Thecountertop 14 provided atop thecabinet 12 may be formed of a durable, and optionally heat-resistant solid material with a flat surface on which food items can be handled and prepared for cooking and/or serving. Illustrative examples of the material from which thecountertop surface 14 can be formed include, but are not limited to, granite, marble, quartz, concrete or the like. - According to one embodiment, the
cooktop 10 includes anadjustable cooking surface 22 that is movable relative to a stationary generator 24 (shown in thecutaway region 26 of thegenerator housing 28 appearing inFIG. 4 ). Thecooking surface 22 is coupled to thegenerator 24 by ahinge 30, for example, such that thecooking surface 22 can be pivoted around thehinge 30 relative to thegenerator 24 along thearcuate path 32 shown for illustrative purposes inFIG. 1 . In other words, thegenerator 24 is installed at a fixed location of thecabinet 12 and is not designed to pivot about thehinge 30 like thecooking surface 22. According to an embodiment of thecooktop assembly 10, thecooking surface 22 can optionally be pivotally adjusted about an axis ofrotation 36 established by thehinge 30 between a cooking orientation as shown inFIGS. 2 and 3 in which an externally-exposedsurface 34 on which a cooking vessel (e.g., pot, pan, etc. . . . ) (not shown) is to be supported while food therein is cooked is substantially horizontal, and a stowed orientation in which the externally-exposedsurface 34 is arranged in a substantially-upright, vertical orientation as shown inFIGS. 1 and 4 ). The externally-exposedsurface 34 of thecooking surface 22 is said to be substantially-horizontal in the cooking orientation, meaning that the externally-exposedsurface 34 is not sloped to an extent that risks allowing the cooking vessel to slide. Also, the externally-exposedsurface 34 of thecooking surface 22 is said to be substantially-vertical in the stowed orientation, meaning that thecooking surface 22 is upright enough to allow the portion of thecountertop 14 that is concealed by thecooking surface 22 in the cooking orientation to be exposed for use in the preparation of food items. In the stowed orientation, thecooking surface 22 remains extended vertically above thecountertop 14 as shown inFIGS. 1 and 4 . According to an embodiment, thecooking surface 22 andhinge 30 can optionally lack a vertically-adjustable support structure that would allow thecooking surface 22, or a substantial portion thereof, to be adjusted to be recessed below thecountertop 14 when not in use to cook food items. - The
cooking surface 22 may be configured in a panel-like shape according to the present embodiment. A glass pane can form the externally-exposedsurface 34, and overlay atray portion 38 with upright side walls forming a bottom and sides of thecooking surface 22. The bottom of thecooking surface 22 opposes, and optionally rests on thecountertop 14 while thecooking surface 22 is in the cooking orientation. For the embodiments shown inFIGS. 1 and 4 , thebottom feature 21 includes an insignia, logo, trademark/service mark, etc. . . . provided to the bottom of thetray portion 38 of thecooking surface 22 to be visible to occupants of the kitchen while thecooking surface 22 is in its stowed orientation. However, thebottom feature 21 can take on any desired appearance and/or structure. For instance, thebottom feature 21 can include a so-called flat-panel television (e.g., LCD, LED, OLED, plasma displays, etc. . . . ) on which motion picture video and/or still images and/or computer-generated images can be displayed, a dry-erase board (e.g., glossy, white or other colored surface for nonpermanent markings), chalkboard, any other surface, and any combination thereof in place of, or in addition to the logo shown in, and described with reference toFIGS. 1 and 4 for illustrative purposes. - At least one, and optionally a plurality (e.g., four (4), five (5), etc. . . . ) heating coils 40 (shown by hidden lines in
FIGS. 1 , 2 and 4) are supported within thetray portion 38 and concealed by the glass pane forming the externally-exposedsurface 34 of thecooking surface 22. A space or other suitable duct can be established between the one or more heating coils 40 and the glass pane on which the cooking vessel is to be supported to allow for the passage of cooling air there through to provide a cooling effect to the heating coil(s) 40. The components included as part of thecooking surface 22 can be kept to a minimum to minimize the profile of thecooking surface 22 resting on thecountertop 14 in the cooking orientation. According to alternate embodiments of thecooktop assembly 10, of all of the electronic components utilized to conduct electric currents to inductively heat the cooking vessel, thecooking surface 22 can be limited to include only thecoils 40 and optionally a portion of the cable(s) 42 described below can be housed within thecooking surface 22. - Each of the heating coils 40 can be formed as a substantially-flat, spiral coil formed from a length of an electrically-conductive material such as copper, for example, wound several turns in a common plane. To be considered substantially-flat, every turn of the coil does not necessarily have to be arranged exactly in the same common plane, as minor deviations are permissible. However, the major planar surface of the resulting
heating coil 40 closest to the overlaid glass pane of thecooking surface 22, when considered as a whole, should be approximately parallel with the externally-exposedsurface 34 on which cooking vessel rests while being inductively heated. Since thegenerator 24 that drives eachcoil 40 is arranged separate from thecooking surface 22, the cooking surface can optionally have a height (in the vertical dimension, extending normally upward from thecountertop 14 when thecooking surface 22 is viewed in the cooking orientation) that is less than one (1″) inch. Accordingly, the vertical distance from thecountertop 14 to the externally-exposedsurface 34 can be approximately one (1″) inch or less. - In operation to heat a cooking vessel supported on the externally-exposed
surface 34, a high-frequency (e.g., at least 10 kHz, at least 20 kHz, etc. . . . ) alternating current is conducted through the wound coil. The high-frequency alternating current is produced by a collection of electric circuitry referred to herein as thegenerator 24 from an alternating current (e.g., having a voltage of approximately 220 V at a frequency of 50 Hz, or having a voltage of approximately 240 V at 60 Hz) supplied by a conventional AC mains electrical outlet in a residential dwelling. A flexible cable 42 (shown as hidden lines inFIG. 4 ) or other suitable electrically-conductive material extends between thegenerator 24 and at least one, and optionally a plurality of heating coils 40 to conduct the high-frequency electric current between thegenerator 24 and the respective heating coil(s) 40. Thecable 42 can be of a suitable length to maintain the electrical connection between the heating coil(s) 40 and thegenerator 24 regardless of the orientation in which thecooking surface 22 is arranged. - The
generator 24 can optionally be at least partially, and optionally fully, enclosed within a rectangular, box-shapedgenerator housing 28. Thehinge 30, which can optionally include a plurality of concentrically-aligned cylindrical portions, allows thecooking surface 22 to be adjusted toward the horizontal cooking orientation, and adjusted in the opposite direction approximately 90° toward the upright stowed orientation. To minimize the likelihood of damage to thecooking surface 22 and/orunderlying countertop 14 from the inadvertent dropping of thecooking surface 22, the cooktop assembly can optionally be provided with a dampingdevice 44 to slow pivotal adjustment of thecooking surface 22 toward thecountertop 14 from a rate at which thecooking surface 22 would otherwise drop under the force of gravity alone, without the damping device 44 (an “undamped” rate). Shown as hidden lines inFIGS. 1 and 4 , the damping device can optionally include a fluid-filled cylinder containing relatively-adjustable segments, the relative rotation of which are impeded by a viscous (e.g., having a greater viscosity than water at room temperature and pressure) fluid. According to embodiments of thecooking apparatus 10, the dampingdevice 44 can be enclosed within a cylindrically-shapedhinge 30. - Installed on the
cabinet 12, thehinge 30 can be at least partially inserted into an aperture formed adjacent to a rearward region of thecountertop 14. The aperture may have inside dimensions similar to the external dimensions of thehinge 30. According to the embodiments illustrated inFIGS. 1-4 , thegenerator housing 28 extends downwardly, through the aperture into an interior (e.g., within the storage space 20) of thecabinet 12, or optionally reward of the storage space 20 (e.g., between a wall and a rear partition establishing the depth of the storage space 20). Parts of thecabinet 12 may be cut out or otherwise customized to accommodate installation of thecooktop assembly 10. - The
cooktop assembly 10 can also optionally include one ormore air inlets 48, shown inFIG. 5 , through which cooling air can enter thegenerator housing 28. Theinlet 48 can be formed as a grate or other restricted aperture, optionally adjacent to a lower region of thegenerator housing 28 in the vertical orientation, where cooler air than that adjacent to the uppermost region of thegenerator housing 28 near thehinge 30 may be available. Cooling air entering thegenerator housing 28 through theair inlet 48 can optionally pass over the circuitry forming thegenerator 24 through natural convection or forced convection created through operation of a fan such as a so-called squirrel-cage blower or fan 50 (FIG. 5 ), thereby providing a cooling effect to that circuitry as the cooling air travels upward, generally toward thehinge 30. According to the embodiment illustrated inFIG. 5 , the cooling air may follow a path indicated generally by arrow 52, and enter the cooktop assembly adjacent the lower region of thegenerator housing 28, move upward therein, and then exit thegenerator housing 28 to be introduced to a duct within the interior of thehinge 30. The cooling air is then expelled from thehinge 30 into the duct between the heating coil(s) 40 and the glass pane forming the externally-exposedsurface 34, where it cools the heating coil(s) 40 en route to being expelled from aforward region 54 of thecooking surface 22 as illustrated by the move past the hinge and the induction coils, and exit at the front of the cooking surface 22 (FIG. 5 ). - As shown in
FIGS. 6 and 7 , another embodiment of thecooktop assembly 10 may be configured similarly so as to include thehinge 30 and thecooking surface 22, but lack the vertically-oriented,upright generator housing 28 of the preceding embodiments. Instead, thecooking surface 22 include a substantially-cylindrically shapedhinge housing 60 that houses the circuitry forming thegenerator 24 that supplies the high-frequency electric current required to power the heating coil(s) 40. Thus, according to the present embodiment, thegenerator 24 is disposed within an interior cavity defined by thehinge 30. Similar to the preceding embodiments, thehinge 30 may be at least partially inserted into an aperture formed adjacent to a rearward portion of thecabinet countertop 14. In the present embodiment, however, thehinge housing 60 includes anair inlet 62 through which cooling air can enter a duct or other interior passage defined in thehinge housing 60. Again, a suitable fan orblower 64 can be provided to achieve the desired airflow through thehinge housing 60 and/orcooking surface 22. Just as for the preceding embodiments, the cooling air exiting thehinge housing 60 in a forward direction can be introduced to a duct, the space between the one or more heating coils 40 and the glass pane on which the cooking vessel is to be supported, or other interior passage defined within thecooking surface 22 to provide a cooling effect to the heating coil(s) 40, and optionally other features involved in inducing the electric current in the cooking vessel, before being exhausted from aforward region 54 of thecooking surface 22 in the direction generally parallel to the direction indicated byarrow 66. Additionally, or alternately, the cooling air can be directed along a length of thehinge 30 in the direction ofarrow 68, in a transverse direction relative to the cooling air path indicated byarrow 66. Thus, some embodiments of thecooktop assembly 10 can be configured to achieve a multi-dimensional cooling effect for different portions of thecooktop assembly 10. - Any of the embodiments described herein can optionally include a balance spring in place of, or in addition to the damping
device 44, to support at least a portion of the cooking surface's 22 weight and give the impression that thecooking surface 22 is lightweight. The balance spring can optionally be a helical spring or other suitable device, optionally disposed within thehinge 30 similar to the dampingdevice 44, to provide thecooking surface 22 with a near “neutral buoyancy” that allows thecooking surface 22 to be raised by the application of a force that is less than would be required to pivotally adjust thecooking surface 22 without the balance spring. - Moreover, the
cooktop assembly 10 may be provided with a controller that turns off and/or interferes with activation of all heat-generating operations once thecooking surface 22 is adjusted away from the cooking orientation. Such a feature can be embodied in a number of ways such as a switch, a level sensor, or parts provided on a printed circuit board. Furthermore, thecooktop assembly 10 may also be provided with a locking feature that prevents movement of thecooking surface 22 away from the cooking orientation if the presence of a kitchenware is sensed on the externally-exposed surface. For example, an inductive signal can be generated by the heating coil(s) 40 or by a sensor adjacent to the heating coil(s) 40, or a weight sensor can be utilized to detect the presence of the cooking vessel or other foreign object. Thus, the locking feature, which can be positioned adjacent to the damping device within thehinge 30, would allow thecooking surface 22 to be raised only if no item is present on the externally-exposed surface of thecooking surface 22. This can be enabled by using induction coils with a pan sense capability. - The entirety of the
cooktop assembly 10 may be “factory-made”, ready for installation, such that thegenerator 24, hinge 30 and heating coil(s) 40 require no assembly at the site of installation by the end-user or service technician, and only the mounting of thecooktop assembly 10 to thecabinet 12 is necessary. This is beneficial with respect to the heating coil(s) 40 which are high voltage, high current and high frequency devices. Because the quality and torque of the connection of the heating coil(s) to thegenerator 24 can affect proper operation of thecooktop assembly 10, distributing thecooktop assembly 10 in a factory-made form ensures proper assembly is achieved. - The aforementioned embodiments of the
cooktop assembly 10 allow the space underneath thecooking surface 22 to be used as countertop space for preparation of food items to be served and/or cooked. It is also possible to configure the cabinet with drawers directly below the cooking surface because the space directly underneath thecooking surface 22 and the cooking surface when the cooktop assumes the lowered position is not occupied by components of the cooktop. - Illustrative embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above devices and methods may incorporate changes and modifications without departing from the general scope of this invention. It is intended to include all such modifications and alterations within the scope of the present invention. Furthermore, to the extent that the term “includes” is used in either the detailed description or the claims, such term is intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
