Description:
FIELD OF THE TECHNOLOGY 
       [0001]    The present technology relates to a domestic cooking appliance. More particularly, the present technology relates to an enhancement for a domestic cooking appliance where different modules can be detected and/or controlled. 
       BACKGROUND 
       [0002]    In the modern kitchen, one common appliance is a domestic cooking appliance, e.g., a cooktop, which may be a stand alone unit or combined with other devices such as an oven or range. Most domestic cooking appliances include one or more heat generating or cooking devices. Some common devices include gas burners, resistive heaters, and inductive heaters, all of which can be provided in various sizes and configurations. 
         [0003]    Generally, domestic cooking appliances come with a fixed configuration of heat generating devices, typically of one type. For example, a domestic cooking appliance usually includes only one of gas, resistive or inductive heating. A common configuration is one large, two medium and one small heat generating device. 
       BRIEF SUMMARY 
       [0004]    Custom kitchens are very desirable in contemporary households. To meet the need of customizable kitchens, custom appliances are also desirable. However, in order to meet a desired level of customization, a very large number of traditional domestic cooking appliances would need to be provided by a single manufacturer because more than the more common heat generating devices such as gas burners, resistive heaters and inductive heaters are desired. A wide array of devices such as a gas burner, a resistive heater, an induction heater, a griddle, a grill, a steamer, and a teppan yaki, perhaps with different sizes of each, is desirable in a domestic cooking appliance for a custom kitchen. However, to provide domestic cooking appliances with all of these devices in all possible configurations is not practically feasible from a manufacturing standpoint. One option would be to design and manufacture each possible configuration, but this likely would result in too many custom parts and configurations. Another option would be to include all appropriate electrical connections, including power and control, for all possible configurations and then populate each location on the domestic cooking appliance with the desired devices. This also is not desirable at least because a wiring harness with appropriate connectors and wiring provided to each location on the domestic cooking appliance would be overly cumbersome and expensive. 
         [0005]    Thus, a need has developed to address one or more shortcomings of the prior art. 
         [0006]    The present technology addresses one or more the shortcomings of the prior art. 
         [0007]    An aspect of the present technology includes a domestic cooking appliance with a plurality of bays adapted to receive a plurality of different types of modules, e.g., modules adapted to provide different functions, detect the type of module and control the type of module. 
         [0008]    Another aspect of the present technology includes a domestic cooking appliance comprising a cooktop including a plurality of bays adapted to receive a plurality of different types of modules; a module connected to a bay of the plurality of bays; and a controller, wherein the controller is adapted to determine the bay in which the module is connected and a type of the module of the plurality of different types of modules. 
         [0009]    In examples, (a) the plurality of bays each comprise a first connector and the module comprises a second connector adapted to mate with the first connector, and the controller determines the type of the module of the plurality of different types of modules based upon a configuration of the second connector, (b) the first connector is an electrical connector, (c) the second connector comprises a plurality of pins and a jumper configuration between pins that causes the plurality of pins to generate a binary code when power is supplied to the plurality of pins, (d) the jumper configuration between pins includes no jumpers between pins, (e) the jumper configuration between pins includes one jumper between two pins, (f) the jumper configuration between pins includes a first jumper between a first pin and a second pin and a second jumper between a third pin and a fourth pin, (g) the controller determines the type of the module based upon a code assigned to the type of module, (h) the plurality of different types of modules comprises one or more of a gas burner, a resistive heater, an induction heater, a griddle, a grill, a steamer, and a teppan yaki, (i) the bays are cooktop bays and the plurality of different types of modules are cooktop modules, (j) the domestic cooking appliance further comprises a non-cooktop bay, and a non-cooktop module connected to the non-cooktop bay, and the controller is adapted to determine a type of the non-cooktop module, (k) the non-cooktop module comprises an oven, a warming drawer, or a steam oven, (l) the domestic cooking appliance further comprises a display, wherein the controller is adapted to update the display to indicate the bay in which the module is connected, (m) the domestic cooking appliance further comprises a display, wherein the controller is adapted to update the display to indicate the bay in which the module is connected and the type of module, (n) the domestic cooking appliance further comprises a combination of modules, including the module, connected to the plurality of bays, and the controller is adapted to determine whether the combination of modules together requires an excessive amount of electrical current, and disable at least one module of the combination of modules to prevent excessive current consumption by the domestic cooking appliance, (o) the domestic cooking appliance further comprises a display, wherein the controller is adapted to update the display to indicate the at least one disabled module, (p) the controller determines the at least one module to disable by allowing other modules that are previously powered to remain powered, (q) a first bay of the plurality of bays comprises a first connector, a second bay of the plurality of bays includes a second connector, and the first connector and the second connector are configured to mate with different connectors, (r) the different connectors are associated, respectively, with the plurality of different types of modules, and/or (s) the first connector and the second connector have different structural configurations of their respective mating interfaces. 
         [0010]    Another aspect of the present technology includes a domestic cooking appliance comprising a plurality of bays adapted to receive a plurality of different types of modules, a plurality of modules each connected to a different bay of the plurality of bays, and a controller, wherein the controller is adapted to determine whether the plurality of modules together require an excessive amount of current, and disable a portion of the plurality of modules to prevent excessive current consumption by the domestic cooking appliance. 
         [0011]    In examples, (a) the domestic cooking appliance further comprises a display, wherein the controller is adapted to update the display to indicate a type of module in each of the plurality of bays and to indicate which of the plurality of modules are disabled, (b) the controller determines the portion of the plurality of modules to disable by allowing other modules that are previously powered to remain powered, (c) the controller is adapted to determine a type of module of the plurality of different types of modules, (d) the controller associates a maximum power consumption the type of module and prevents the type of module from being turned on if doing so will cause the domestic cooking appliance to exceed a predetermined power threshold, and/or (e) the controller determines the type of module based upon a configuration of a connector of the type of module. 
         [0012]    Another aspect of the present technology includes a method of controlling a domestic cooking appliance with a plurality of modules connected to the domestic cooking appliance, the method comprising: operating a first module; determining whether a second module can be operated without exceeding a predetermined power threshold; and powering the second module when the predetermined power threshold is not exceeded and preventing the second module from operating when the predetermined power threshold is exceeded.

         [0015]    In an example, the module recognition interface uses a jumper configuration associated with each different type of module to identify the type of module positioned in a respective bay. 
         [0016]    Other aspects, features, and advantages of this technology will become apparent from the following detailed description when taken in conjunction with the accompanying drawings, which are a part of this disclosure and which illustrate, by way of example, principles of this technology.

     DETAILED DESCRIPTION 
       [0021]    The following description is provided in relation to several examples which may share common characteristics and features. It is to be understood that one or more features of any one example may be combinable with one or more features of the other examples. In addition, any single feature or combination of features in any of the examples may constitute additional examples. 
         [0022]    Throughout this disclosure, terms such as first, second, third, etc. may be used. However, these terms are not intended to be limiting or indicative of a specific order, but instead are used to distinguish similarly described features from one another, unless expressly noted otherwise. Throughout this disclosure, “substantially” includes at least deviations from ideal or nominal values that are within manufacturing, operational and/or inspection tolerances. 
         [0023]    The term electrical connector is also used throughout this disclosure. A connector encompasses at least an electrical connection, e.g., with a plug and/or receptacle, and may also encompass, additionally or alternatively, similar and/or related structures such as pin(s), jumper(s) between pin(s), wiring and/or wiring harness(es), etc. 
         [0024]      FIG. 1  illustrates an exemplary but non-limiting domestic cooking appliance  100  with a cooktop  102 . The cooktop  102  includes a plurality of bays (e.g., four bays  104   a ,  104   b ,  104   c ,  104   d  are illustrated) populated with modules  106 . There are numerous types of modules that may be dictated by the needs and desires of a user. Some exemplary but non-limiting examples of modules are a gas burner, a resistive heater, an induction heater, a griddle, a grill, a steamer, and a teppan yaki. Only two different types of modules are illustrated in  FIG. 1  for ease of illustration only. Any type of module may be included or inserted into each of the bays. The domestic cooking appliance  100  also includes a plurality of non-cooktop bays (e.g., two bays  108   a ,  108   b  are illustrated) populated with non-cooktop modules  110 . Some exemplary but non-limiting examples of non-cooktop modules are an oven, a warming drawer and a steam oven. The domestic cooking appliance  100  is illustrated with two displays  112 , although any number of displays  112  may be included. 
         [0025]      FIG. 2  illustrates an exemplary but non-limiting schematic according to the present technology. The schematic includes seven modules  114 , which may be modules  106  or non-cooktop modules  110 , but any number of modules  114  could be included with the present technology. Each of the modules  114  is at least functionally connected to a configuration module  116 . A functional connection may include a connection that is able to relay information and/or provides electrical signals for control and/or power. 
         [0026]    In  FIG. 2 , the configuration module  116  interfaces with a main control board  118 . Together the configuration module  116  and main control board  118  may be considered a controller  120  for the domestic cooking appliance  100 . Alternatively, either the configuration module  116  or main control board  118  alone may be considered a controller  120  for the domestic cooking appliance  100 . The configuration module  116  and main control board  118  may be physically separate devices or the same physical device, in which case the configuration module  116  and main control board  118  may be considered as functional distinctions within the same physical device. The configuration module  116  and main control board  118  may be in the form of general purpose computers with appropriate programming or special purpose computers or any other suitable control system. 
         [0027]    The functional connection between the modules  114  and the configuration may be in the form of an electrical connector  122 , which is illustrated in greater detail in  FIG. 3 . The electrical connector  122  includes a first mating half  124  associated with a module  114  and a second mating half  126  associated with the configuration module  116 . In an example of the present technology, a first mating half  124  associated with any of the types of modules  114  can physically mate with any second mating half  126 . But as discussed below, each type of module  114  may include a functional difference with the respective first mating half  124 . 
         [0028]    As illustrated in  FIG. 3 , the electrical connector  122  includes signal lines, illustrated as three signal lines S 0 , S 1 , S 2 , and voltage lines, illustrated as three lines with five volts. With this configuration, the electrical connector effectively can function as a three digit binary code by including connections between one or more of the signal lines S 0 , S 1 , S 2  and a voltage line. Thus, the respective first mating half  124  may include a functional difference. Of course, any number signal and voltage lines may be included so as to provide a smaller or larger binary code if necessary. 
         [0029]      FIG. 3  illustrates a jumper  128  or similar electrical connection that connects S 1  to a five volt line. In this configuration, S 0  and S 2  would have zero voltage and S 1  would have a five volt signal, corresponding to a binary number two. Of course, any combination of jumpers  128  or lack of jumper  128  may be provided to correspond to different codes or binary numbers. In the configuration illustrated in  FIG. 3 , from zero to three jumpers  128  could be provided, and of course a higher number is possible if more signal lines are provided. The configuration module  116  may include appropriate logic, either through hardware or software, to identify or correlate a particular binary code with a type of module  114 . Based upon the identified module, appropriate control decisions can be performed by the controller  120  and/or domestic cooking appliance  100 . Use of a jumper  128  across signal lines may be beneficial because it provides a simple and cost effective solution. 
         [0030]    Although an electrical connector  122  with a jumper  128  has been described above, the present technology is not so limited. Any interface that allows for identification of the modules  114  is envisioned with the present technology. For example, any piece of hardware or software that provides appropriate identification may be used. Exemplary but non-limiting examples include radio frequency identification (RFID), software codes accessible by a communications bus, and/or physical keys that provide identification. 
         [0031]    By associating each type of module  114  with a code, the controller  120  can identify the type of module  114  connected in each of the cooktop bays and/or non-cooktop bays. This provides several advantages. 
         [0032]    For example, during the manufacturing process, the domestic cooking appliance  100  can include a wiring harness (not illustrated) that allows any type of module  114  to be connected in any type of bay, either the cooktop bays or the non-cooktop bays. With such a universal wiring harness, customized domestic cooking appliances  100  with any combination of types of modules  114  can be manufactured. If the wiring harness were not universal, providing wiring for each type of module  114  in each possible bay would be prohibitive because of the large number of different parts required. 
         [0033]    The controller  120  can also use the identity of each type of module  114  for control purposes. For example, different types of modules  114  may have very different electrical power consumption requirements—a gas burner may require electrical power only to drive an ignition source whereas an induction heater may continuously draw several amps of electricity during a heating operation. If several induction heaters are operated at the same time, the current draw may be such that the power supply connected to the domestic cooking appliance  100 , or the domestic cooking appliance  100  itself, may be unable to handle the current necessary to operate several induction heaters. In this scenario, the controller  120  can determine that “too many” induction heaters are installed in the domestic cooking appliance  100  and only allow a number of induction heaters to be operated that will remain within an appropriate current level. In other words, if all of the modules  114  installed are induction heaters, and only two induction heaters can be safely operated, the controller  120  can prevent or disable a third module  114  from being operated after two other modules  114  are operated. The controller  120  may allow a first module  114  to be turned on because the current draw is not excessive, followed by a second module  114  and so on until the current limit would be exceeded by turning on another module  114 . At that point, any module  114  that would cause excessive current draw would be prevented from operating. Of course, this control scheme can apply to any type or combination of modules  114  that may draw excessive current or other resource. For example, if a limit is placed on natural gas consumption, gas burners could also be disabled once a limit of gas consumption is reached by one or more other burners. 
         [0034]    The domestic cooking appliance  100  can also use the identification of the modules  114  in conjunction with the display  112 . As illustrated in  FIG. 4 , the display  112  can include symbols  130  or other nomenclature such as text, color-coded lights, images, etc., that corresponds to a type of the module  114 . When the type of module  114  is detected, the display can provide some sort of indication on the display that corresponds to the type of module  114  and location in a given bay  104  or non-cooktop bay  108 . The display can also provide an indication when a module  114  has been disabled, as detailed above, and is shown in  FIG. 4  by way of an “X” through two of the symbols. Any indication that a module  114  has been disabled may be provided. For example, the symbols could be illuminated only when enabled (not disabled), grayed out when disabled, or any other indication that would inform users that the module  114  is disabled or otherwise unavailable. 
         [0035]    Identification of the modules  114  can also be used to reconfigure a domestic cooking appliance  100 . For example, if a new location or configuration of the modules  114  that are installed in a domestic cooking appliance is desired, the modules can be disconnected and moved between locations and the domestic cooking appliance will identify the new locations and operate accordingly. Similarly, spare or new modules  114  could be swapped with existing modules  114  if new or different features are desired for the domestic cooking appliance  100 , and the domestic cooking appliance  100  will identify the new modules  114  and operate accordingly. 
         [0036]    Of course, the preceding examples are not limiting and any changes in the control scheme of the domestic cooking appliance  100  can take advantage of identifying the modules  114  that have been installed in accordance with the present technology. 
         [0037]    While the present technology has been described in connection with several practical examples, it is to be understood that the technology is not to be limited to the disclosed examples, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the technology.
