Description

FIELD OF THE DISCLOSURE

[0001] The present subject matter relates generally to domestic appliances and more particularly to methods of operating domestic appliances during a religious holiday, such as a Sabbath.BACKGROUND OF THE DISCLOSURE

[0002] Certain religious customs, such as Orthodox Jewish customs, require that certain traditions be maintained during designated times or holidays, which can influence how certain appliances, such as an oven appliance, may be used. For instance, the Sabbath (e.g., Shabbos or Shabbat) is set aside as a time when no work should be performed. This prohibition on work may apply not only to an observer's direct physical actions, but also to actions initiated through the observer's appliances. For instance, the observer may be required to abstain from causing an appliance to change its normal pattern of operation. In other words, a user may be prohibited from actions that would result in a direct response from the appliance, such as activating a heating element or heat-adjusting system. Nonetheless, many appliances are configured to provide this kind of direct response. In the field of oven appliances, heating elements are often activated according to a closed-loop algorithm to achieve or maintain a set temperature within the cooking chamber. Thus, a user opening the door to an oven appliance may influence when the heating elements to activate. Unfortunately, such actions may violate the sanctity of the day.

[0003] In order to properly observe certain religious holidays (e.g., Sabbath or other Orthodox Jewish customs), some appliances provide a method of manually disabling certain functions. Other appliances adjust functions to be more in line with religious law. For instance, features that normally (e.g., at times other than the Sabbath) operate according to a measured condition may be instead operated according to a set timer for the duration of the Sabbath. For example, in the case of oven appliances, heating elements may be selectively turned on and off according to a basic timer or timed cycle. As another example, in the case of a refrigerator appliance, one or more inputs may be configured to disable electrical displays or lights within the refrigerator appliance. In today's world, individuals who observe the Sabbath often share a space with those who do not. To uphold their Sabbath practices, they may set shared appliances, such as refrigerators, to a Sabbath operation mode. However, this can cause inconvenience for individuals who do not observe the Sabbath, as they may be unable to access certain functions or settings on the appliances.

[0004] Accordingly, systems and methods for a domestic appliance that can obviate one or more of the above-mentioned drawbacks would be beneficial.BRIEF DESCRIPTION OF THE DISCLOSURE

[0005] Aspects and advantages of the invention will be set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.

[0006] In one exemplary aspect of the present disclosure, a method of operating a domestic appliance is provided. The method may include determining an anticipated Sabbath condition at the domestic appliance. The method may also include directing the domestic appliance to a Sabbath-compliant state based on the anticipated Sabbath condition. The method may also include receiving a non-observing signal following directing the domestic appliance to the Sabbath-complaint state. The method may also include temporarily directing the domestic appliance to a non-observing state in response to receiving the non-observing signal, the non-observing state being based on the non-observer condition.

[0007] In another exemplary aspect of the present disclosure, a domestic appliance is provided. The domestic appliance may include a cabinet. The domestic appliance may include a controller configured to initiate a temporary non-observing state.

[0017] Repeat use of reference characters in the present specification and drawings is intended to represent the same or analogous features or elements of the present invention.DETAILED DESCRIPTION

[0018] Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.

[0019] As used herein, the terms “first,”“second,” and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. The terms “includes” and “including” are intended to be inclusive in a manner similar to the term “comprising.” Similarly, the term “or” is generally intended to be inclusive (e.g., “A or B” is intended to mean “A or B or both”). In addition, here and throughout the specification and claims, range limitations may be combined or interchanged. Such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise. For example, all ranges disclosed herein are inclusive of the endpoints, and the endpoints are independently combinable with each other. The singular forms “a,”“an,” and “the” include plural references unless the context clearly dictates otherwise.

[0020] Approximating language, as used herein throughout the specification and claims, may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “generally,”“about,”“approximately,” and “substantially,” are not to be limited to the precise value specified. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value, or the precision of the methods or machines for constructing or manufacturing the components or systems. For example, the approximating language may refer to being within a 10 percent margin (e.g., including values within ten percent greater or less than the stated value). In this regard, for example, when used in the context of an angle or direction, such terms include within ten degrees greater or less than the stated angle or direction (e.g., “generally vertical” includes forming an angle of up to ten degrees in any direction, such as, clockwise or counterclockwise, with the vertical direction V).

[0021] The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” In addition, reference to “an embodiment” or “one embodiment” does not necessarily refer to the same embodiment, although it may. Any implementation described herein as “exemplary” or “an embodiment” is not necessarily to be construed as preferred or advantageous over other implementations.

[0022] Except as explicitly indicated otherwise, recitation of a singular processing element (e.g., “a controller,”“a processor,”“a microprocessor,” etc.) is understood to include more than one processing element. In other words, “a processing element” is generally understood as “one or more processing element.” Furthermore, barring a specific statement to the contrary, any steps or functions recited as being performed by “the processing element” or “said processing element” are generally understood to be capable of being performed by “any one of the one or more processing elements.” Thus, a first step or function performed by “the processing element” may be performed by “any one of the one or more processing elements,” and a second step or function performed by “the processing element” may be performed by “any one of the one or more processing elements and not necessarily by the same one of the one or more processing elements by which the first step or function is performed.” Moreover, it is understood that recitation of “the processing element” or “said processing element” performing a plurality of steps or functions does not require that at least one discrete processing element be capable of performing each one of the plurality of steps or functions.

[0023] Generally, the present disclosure provides a domestic appliance, such as a domestic appliance that may be found in a household, and a method of operating the appliance during Sabbath. For example, the domestic appliance may be an oven appliance, a refrigerator appliance, water heater appliance, air conditioning unit, microwave oven appliance, dishwasher appliance, laundry appliance, or any other domestic (e.g., household) appliance. The appliance may automatically determine when Sabbath occurs based on a specific geographic location. Moreover, the appliance may automatically enter and remain in a Sabbath-compliant state during Sabbath. The Sabbath-compliant state may prevent a Sabbath observing user from performing any work without having to mentally consider when the Sabbath begins or ends. This may occur, for instance, while still keeping food within the refrigerator appliance cold or at an otherwise suitable temperature.

[0024] Notably, the present disclosure provides a practical and user-friendly solution for non-observing users who share appliance with Sabbath observing users. The present subject matter advantageously provides systems and methods for allowing all users that utilize a shared appliance (e.g., Sabbath observing users and non-Sabbath observing users) to utilize the shared appliance without comprising the religious beliefs or practices of the Sabbath observing users. The present disclosure advantageously provides a method wherein a non-observing state of the domestic appliance can be initiated or directed during the Sabbath. For example, a non-observing user may be able to transmit a signal to the domestic appliance that temporarily directs that domestic appliance to the non-observing state. Thus, the present disclosure may advantageously allow individuals to switch shared appliances to their regular mode temporarily.

[0025] Referring now to the figures, FIG. 1 provides a perspective view of an oven appliance 10 according to an exemplary embodiment of the present disclosure. FIG. 2 provides a section view of oven appliance 10 taken along the 2-2 line of FIG. 1. As may be seen, oven appliance 10 defines a vertical direction V, a lateral direction L and a transverse direction T. The vertical direction V, the lateral direction L and the transverse direction T are mutually perpendicular and form an orthogonal direction system. Oven appliance 10 is provided by way of example only and is not intended to limit the present subject matter in any aspect. Thus, the present subject matter may be used with other oven appliance configurations (e.g., that define one or more interior cavities for the receipt of food or having different pan or rack arrangements than what is shown in FIG. 2). Further, the present subject matter may be used in a stand-alone cooktop, range appliance, or any other suitable appliance.

[0026] Oven appliance 10 generally includes a cooking assembly. In particular, the cooking assembly may include one or more heating elements. For example, in some embodiments, the cooking assembly, and thus the oven appliance 10 includes an insulated cabinet 12 with an interior cooking chamber 14 defined by an interior surface 15 of cabinet 12. Cooking chamber 14 is configured for the receipt of one or more food items to be cooked. Oven appliance 10 includes a door 16 rotatably mounted to cabinet 12 (e.g., with a hinge—not shown). A handle 18 may be mounted to door 16 and assists a user with opening and closing door 16 in order to access cooking chamber 14. For example, a user can pull on handle 18 to open or close door 16 and access cooking chamber 14.

[0027] In some embodiments, oven appliance 10 includes a seal (not shown) between door 16 and cabinet 12 that assists with maintaining heat and cooking fumes within cooking chamber 14 when door 16 is closed as shown in FIG. 2. Multiple parallel glass panes 22 may provide for viewing the contents of cooking chamber 14 when door 16 is closed and assist with insulating cooking chamber 14. A baking rack 24 is positioned in cooking chamber 14 for the receipt of food items or utensils containing food items. Baking rack 24 is slidably received onto embossed ribs or sliding rails 26 such that rack 24 may be conveniently moved into and out of cooking chamber 14 when door 16 is open.

[0028] In certain embodiments, a gas fueled or electric bottom heating element 40 (e.g., a gas burner, a radiant heating element, microwave heating element, or a resistive heating element) is positioned in cabinet 12, for example, at a bottom portion 30 of cabinet 12. Bottom heating element 40 is used to heat cooking chamber 14 for both cooking and cleaning of oven appliance 10. The size and heat output of bottom heating element 40 can be selected based on, for example, the size of oven appliance 10.

[0029] In additional or alternative embodiments, a top heating element 42 (e.g., a gas burner, a radiant heating element, or a resistive heating element) is positioned in cooking chamber 14 of cabinet 12, for example, at a top portion 32 of cabinet 12. Top heating element 42 is used to heat cooking chamber 14 for both cooking / broiling and cleaning of oven appliance 10. Like bottom heating element 40, the size and heat output of top heating element 42 can be selected based on for example, the size of oven appliance 10.

[0030] As shown in FIG. 2, in certain embodiments, a cooling air flow passageway 28 can be provided within cabinet 12 between cooking chamber 14 and cooktop 70. For example, a portion of passageway 28 may be between cooking chamber 14 and cooktop 70 along a vertical direction V. Passageway 28 is shown schematically in the figures. As will be understood by one of skill in the art using the teachings disclosed herein, cooling air flow passageway 28 may have a variety of configurations other than as shown. Air flowing through passageway 28 can provide convective cooling.

[0031] In optional embodiments, the oven appliance 10 additionally includes a cooktop 70. Cooktop 70 may be disposed on the cabinet 12 such that the total volume of cabinet 12 is generally divided between the cooking chamber 14 and cooktop 70. As shown, cooktop 70 may include a top panel 72. By way of example, top panel 72 may be constructed of glass, ceramics, enameled steel, and combinations thereof. Heating assemblies 74 (e.g., induction heating elements, resistive heating elements, radiant heating elements, or gas burners) may be mounted, for example, on or below the top panel 72. While shown with four heating assemblies 74 in the exemplary embodiment of FIG. 1, cooktop 70 may include any number of heating assemblies 74 in alternative exemplary embodiments. Heating assemblies 74 can also have various diameters. For example, each heating assembly of heating assemblies 74 can have a different diameter, the same diameter, or any suitable combination thereof.

[0032] As shown, oven appliance 10 includes a user interface panel 76, which may be located as shown, within convenient reach of a user of the oven appliance 10. User interface panel 76 is generally a component that allows a user to interact with the oven appliance 10 to, for example, turn various heating elements (such as heating elements 40, 42, 74) on and off, adjust the temperature of the heating elements, set built-in timers, etc. Although user interface panel 76 is shown mounted to a backsplash fixed to cabinet 12, alternative embodiments may provide user interface panel 76 at another suitable location (e.g., on a front portion of cabinet 12 above door 16).

[0033] In some embodiments, a user interface panel 76 may include one or more user-interface inputs78 and a graphical display 80, which may be separate from or integrated with the user-interface inputs 78. The user-interface inputs 78 may include analog control elements (e.g., knobs, dials, or buttons) or digital control elements, such as a touchscreen comprising a plurality of elements thereon. Various commands for a user to select through the engagement with the user-interface inputs 78 may be displayed (e.g., by touchscreen at the inputs 78 or by the graphical display 80), and detection of the user selecting a specific command may be determined by a controller 50 (e.g., described in more detail below), which is in communication with the user-interface inputs 78, based on electrical signals therefrom. Additionally or alternatively, graphical display 80 may generally deliver certain information to the user, which may be based on user selections and interaction with the inputs 78, such as whether a one or more heating elements 40, 42 within cooking chamber 14 are activated, the temperature at which cooking chamber 14 is set, or whether a holiday mode (e.g., Sabbath-compliant state) has been initiated. In certain embodiments, a discrete holiday mode input is included with the inputs 78. User engagement of the holiday mode input may activate the oven appliance 10 or initiate a particular cooking operation (e.g., such as method 300, described below with respect to FIG. 6).

[0034] Generally, oven appliance 10 includes a controller 50 that controls operation of the various components of the oven appliance 10. Controller 50 may include a memory (e.g., non-transitive media) and microprocessor, such as a general or special purpose microprocessor operable to execute programming instructions or micro-control code associated with a cleaning cycle. The memory may represent random access memory such RAM, ROM, EEPROM, EPROM, flash memory devices, magnetic disks, etc., and combinations thereof. The memory devices can store data and instructions that are executed by the processor to cause oven appliance 10 to perform various operations. For example, instructions could be instructions for directing activation of one or more of the heating elements 40, 42, such as may be provided according to one or more programmed cooking modes or operations (e.g., such as method 300, described below with respect to FIG. 6).

[0035] In some embodiments, controller 50 is in operable (e.g., wired or wireless) communication with a temperature sensor 55 (e.g., thermistor, thermocouple, etc.) disposed within cabinet 12 (e.g., within cooking chamber 14 or otherwise in thermal communication with cooking chamber 14) to detect a temperature at cooking chamber 14.

[0036] Referring now to FIG. 3, a perspective view of a refrigerator appliance 100 according to an example embodiment of the present disclosure is provided. FIG. 4 provides another perspective view of refrigerator appliance when one or more doors 128, 130 are open. Refrigerator appliance 100 includes a cabinet or housing 120 that extends between a top portion 104 and a bottom portion 106 along a vertical direction V, between a first side 108 and a second side 110 along a lateral direction L, and between a front side 112 and a rear side 114 along a transverse direction T. Each of the vertical direction V, lateral direction L, and transverse direction T are mutually perpendicular to one another and form an orthogonal direction system.

[0037] Housing 120 defines chilled chambers for receipt of food items for storage. In particular, housing 120 defines fresh food chamber 122 positioned at or adjacent top portion 104 of housing 120. Refrigerator appliance 100 also includes a freezer chamber 124 that is, for example, arranged at or adjacent bottom portion 106 of housing 120. As such, refrigerator appliance 100 is generally referred to as a bottom mount refrigerator. It is recognized, however, that the benefits of the present disclosure apply to other types and styles of refrigerator appliances such as, e.g., a top mount refrigerator appliance or a side-by-side style refrigerator appliance. Consequently, the description set forth herein is for illustrative purposes only and is not intended to be limiting in any aspect to any particular chilled chamber configuration.

[0038] Refrigerator doors 128 are rotatably hinged to an edge of housing 120 for selectively accessing fresh food chamber 122. In addition, a freezer door 130 is arranged below refrigerator doors 128 for selectively accessing freezer chamber 124. Freezer door 130 is coupled to a freezer drawer (not shown) slidably mounted within freezer chamber 124. Refrigerator doors 128 and freezer door 130 are shown in a closed configuration in FIG. 1.

[0039] Refrigerator appliance 100 also includes a dispensing assembly 140 for dispensing liquid water or ice. Dispensing assembly 140 includes a dispenser 142 positioned on or mounted to an exterior portion of refrigerator appliance 100, e.g., on one of doors 128. Dispenser 142 includes a discharging outlet 144 for accessing ice and liquid water. An actuating mechanism 146, shown as a paddle, is mounted below discharging outlet 144 for operating dispenser 142. In alternative example embodiments, any suitable actuating mechanism may be used to operate dispenser 142. For example, dispenser 142 can include a sensor (such as an ultrasonic sensor) or a button rather than the paddle. A user interface panel 148 is provided for controlling the mode of operation. For example, user interface panel 148 includes a plurality of user inputs (not labeled), such as a water dispensing button and an ice-dispensing button, for selecting a desired mode of operation such as crushed or non-crushed ice.

[0040] Discharging outlet 144 and actuating mechanism 146 are an external part of dispenser 142 and are mounted in a dispenser recess 150. Dispenser recess 150 is positioned at a predetermined elevation convenient for a user to access ice or water and enabling the user to access ice without the need to bend-over and without the need to open doors 128. In example embodiments, dispenser recess 150 is positioned at a level that approximates the chest level of a user.

[0041] As shown, for instance in FIG. 4, at least one door 128 may define a sub-compartment, e.g., icebox compartment 160. Icebox compartment 160 extends into fresh food chamber 122 when refrigerator door 128 is in the closed position. Although icebox compartment 160 is shown in door 128, additional or alterative embodiments may include an icebox compartment defined within door 130. As discussed in greater detail below, an ice making assembly or icemaker (not pictured) may be positioned or disposed within icebox compartment 160. Thus, ice may be supplied to dispenser recess 150 (see FIG. 1) from the ice making assembly or icemaker in icebox compartment 160 on a back side of refrigerator door 128.

[0042] An access door—e.g., icebox door 162—may be hinged to icebox compartment 160 to selectively cover or permit access to opening of icebox compartment 160. Icebox door 162 permits selective access to icebox compartment 160. Any manner of suitable latch 164 is provided with icebox compartment 160 to maintain icebox door 162 in a closed position. As an example, latch 164 may be actuated by a consumer in order to open icebox door 162 for providing access into icebox compartment 160. Icebox door 162 can also assist with insulating icebox compartment 160, e.g., by thermally isolating or insulating icebox compartment 160 from fresh food chamber 122. This thermal insulation helps maintain icebox compartment 160 at a temperature below the freezing point of water. In addition icebox compartment 160 may receive cooling air from a chilled air supply duct 166 and a chilled air return duct 168 disposed on a side portion of housing 120 of refrigerator appliance 100. In this manner, the supply duct 166 and return duct 168 may recirculate chilled air from a suitable sealed cooling system 200 (see FIG. 3) through icebox compartment 160.

[0043] Operation of the refrigerator appliance 100 can be generally controlled or regulated by a controller 190 (see FIG. 5; see also 190A and 190B). As will be described in greater detail below, controller 190 may include multiple modes of operation (e.g., a Sabbath-compliant state and a non-Sabbath-compliant state) that control or regulate various portions of refrigerator appliance 100 according to one or more discrete criteria. In other words, controller 190 may be configured to control refrigerator appliance 100 differently in a non-Sabbath-compliant state than in a Sabbath-compliant state.

[0044] In some embodiments, controller 190 is operatively coupled to user interface panel 148 or various other components, as will be described below. User interface panel 148 provides selections for user manipulation of the operation of refrigerator appliance 100 (e.g., during a non-Sabbath-compliant state of operation). As an example, user interface panel 148 may provide for selections between whole or crushed ice, chilled water, or specific modes of operation. In response to one or more input signals (e.g., from user manipulation of user interface panel 148 or one or more received sensor signals), controller 190 may operate various components of the refrigerator appliance 100 according to the current mode of operation.

[0045] Controller 190 may include a memory and one or more microprocessors, CPUs or the like, such as general or special purpose microprocessors operable to execute programming instructions or micro-control code associated with operation of refrigerator appliance 100. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In some embodiments, the processor executes programming instructions stored in memory. For certain embodiments, the instructions include a software package configured to operate appliance 100 and, e.g., execute an operation routine including the example method 300 described below with reference to FIG. 6. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively, controller 190 may be constructed without using a microprocessor, e.g., using a combination of discrete analog or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.

[0046] Controller 190, or portions thereof, may be positioned in a variety of locations throughout refrigerator appliance 100. In example embodiments, controller 190 is located within the user interface panel 148. In other embodiments, the controller 190 may be positioned at any suitable location within refrigerator appliance 100, such as for example within a fresh food chamber, a freezer door, etc. In additional or alternative embodiments, controller 190 is formed from multiple controllers or controller components mounted at discrete locations within or on refrigerator appliance 100. For instance, as illustrated in FIG. 3, a primary controller 190A may be mounted at one location (e.g., within the user interface panel 148) while a secondary controller 190B may be mounted at another location (e.g., within cabinet 120). Input / output (“I / O”) signals may be routed between controller 190 and various operational components of refrigerator appliance 100. For example, user interface panel 148 may be operatively coupled to controller 190 via one or more signal lines or shared communication busses.

[0047] In some embodiments, one or more temperature sensors 180 are included with refrigerator appliance 100. As an example, a temperature sensor 180 may be in operable communication with a refrigerated chamber 122 or 124 of the refrigerator appliance 100. One or more temperature sensors 180 may be mounted to a liner 132 within cabinet 120. During operations, temperature sensor 180 may thus detect the temperature within refrigerated chamber 122 or 124. As another example, a temperature sensor 180 may be mounted in operable communication with the ambient environment (e.g., the area outside of refrigerator appliance 100). One or more temperature sensors 180 may be mounted to an outer portion of cabinet 120. During operations, temperature sensor 180 may thus detect the ambient temperature for the area surrounding cabinet 120.

[0048] Temperature sensor 180 may be any suitable temperature sensor operatively coupled to controller 190. For example, temperature sensor 180 may be a thermistor, a thermocouple, a resistance thermometer, etc. During certain operations, measurements from temperature sensor 180 may be utilized to initiate or terminate one or more cycles of sealed cooling system 200, as will be described in detail below.

[0049] In additional or alternative embodiments, a door switch 182 is provided in operable communication with one or more corresponding doors 128, 130 of refrigerator appliance 100. In certain modes of operation (e.g., during a non-Sabbath-compliant state of operation), an internal light 184 within refrigerator appliance 100 may be illuminated or dimmed based on whether the corresponding door (e.g., one of doors 128) is detected as being opened (see FIG. 4) or closed (see FIG. 3). Door switch 182 may be positioned at any suitable location to detect the opening / closing of the corresponding door 128 (e.g., along a door 128). Although illustrated as a mechanical plunger switch, door switch 182 may be any suitable position sensor configured to detect the closed or open location(s) of a corresponding door 128.

[0050] In some embodiments, controller 190 is operatively coupled to the various components of dispensing assembly 140 and may control operation of the various components. For example, the various valves, switches, etc. may be actuatable based on commands from the controller 190 (e.g., during a non-Sabbath-compliant state of operation). As discussed, interface panel 148 may additionally be operatively coupled to the controller 190. Thus, the various operations may occur based on user input or automatically through controller 190 instruction.

[0051] Referring now to FIG. 5, refrigerator appliance 100 may include a sealed refrigeration or cooling system 200. In general, sealed cooling system 200 is charged with a refrigerant that is flowed through various components and facilitates cooling of the fresh food compartment 122 and the freezer compartment 124. Sealed cooling system 200 may be charged or filled with any suitable refrigerant, such as R441A, R600a, R600, R290, etc.

[0052] Sealed cooling system 200 includes a compressor 202 for compressing the refrigerant, thus raising the temperature and pressure of the refrigerant. Compressor 202 may for example be a variable speed compressor 202, such that the speed of the compressor 202 can be varied between zero (0) and one hundred (100) percent by controller 190. Sealed cooling system 200 may further include a condenser 204, which may be disposed downstream of compressor 202, e.g., in the direction of flow of the refrigerant. Thus, condenser 204 may receive refrigerant from the compressor 202, and may condense the refrigerant by lowering the temperature of the refrigerant flowing therethrough due to, e.g., heat exchange with ambient air. A condenser fan 206 may be used to force air over condenser 204 as illustrated to facilitate heat exchange between the refrigerant and the surrounding air. Condenser fan 206 can be a variable speed fan—meaning the speed of condenser fan 206 may be controlled or set anywhere between and including, e.g., zero (0) and one hundred (100) percent. The speed of condenser fan 206 can be determined by, and communicated to, fan 206 by controller 190, e.g., in certain modes of operation.

[0053] Sealed cooling system 200 further includes an evaporator 210 disposed downstream of the condenser 204. Additionally, an expansion device 208 may be utilized to expand the refrigerant, thus further reduce the pressure of the refrigerant, leaving condenser 204 before being flowed to evaporator 210. Evaporator 210 generally is a heat exchanger that transfers heat from air passing over the evaporator 210 to refrigerant flowing through evaporator 210, thereby cooling the air and causing the refrigerant to vaporize. An evaporator fan 212 may be used to force air over evaporator 210 as illustrated. As such, cooled air is produced and supplied to refrigerated compartments 122, 124 of refrigerator appliance 100. In certain embodiments, evaporator fan 212 can be a variable speed evaporator fan 212—meaning the speed of fan 212 may be controlled or set anywhere between and including, e.g., zero (0) and one hundred (100) percent. The speed of evaporator fan 212 can be determined by, and communicated to, evaporator fan 212 by controller 190, e.g., in certain modes of operation.

[0054] Evaporator 210 may be in communication with fresh food compartment 122 and freezer compartment 124 to provide cooled air to compartments 122, 124. Alternatively, sealed cooling system 200 may include more two or more evaporators 210, such that at least one evaporator 210 provides cooled air to fresh food compartment 122 and at least one evaporator 210 provides cooled air to freezer compartment 124. In other embodiments, evaporator 210 may be in communication with any suitable component of the refrigerator appliance 100. For example, in some embodiments, evaporator 210 may be in communication with the ice maker (e.g., during a non-Sabbath-compliant state of operation), such as with an ice compartment of the ice maker. From evaporator 210, refrigerant may flow back to and through compressor 202, which may be downstream of evaporator 210, thus completing a closed refrigeration loop or cycle.

[0055] As shown in FIG. 5, a defrost heater 214 may be utilized to defrost evaporator 210, e.g., to melt ice that accumulates on evaporator 210. Defrost heater 214 may be positioned adjacent or in close proximity (e.g., below) evaporator 210 within fresh food compartment 122 or freezer compartment 124. In certain modes of operation, defrost heater 214 may be activated periodically; that is, a period of time tice elapses between when defrost heater 214 is deactivated and when defrost heater 214 is reactivated to melt a new accumulation of ice on evaporator 210. The period of time tice may be a preprogrammed period such that time tice is the same between each period of activation of defrost heater 214 (e.g., during a Sabbath-compliant state of operation), or the period of time may vary (e.g., during a non-Sabbath-compliant state of operation). Additionally or alternatively, in certain modes of operation (e.g., a non-Sabbath-compliant state of operation) defrost heater 214 may be activated based on some other condition, such as the temperature of evaporator 210 or any other appropriate condition.

[0056] In some embodiments, a defrost termination thermostat 216 may be used to monitor the temperature of evaporator 210 (e.g., during a non-Sabbath-compliant state of operation) such that defrost heater 214 is deactivated when thermostat 216 measures that the temperature of evaporator 210 is above freezing, e.g., greater than thirty-two degrees Fahrenheit (32° F.). In some embodiments, thermostat 216 may send a signal to controller 190 or other suitable device to deactivate defrost heater 214 when evaporator 210 is above freezing. In other embodiments, defrost termination thermostat 216 may comprise a switch such that defrost heater 214 is switched off when thermostat 216 measures that the temperature of evaporator 210 is above freezing.

[0057] As noted above, controller 190 may include multiple unique modes of operation, such as a Sabbath-compliant state and a non-Sabbath-compliant state. Moreover, controller 190 may automatically (e.g., without active user input or engagement) determine when to enter or exit each mode of operation. Moreover, controller 190 may automatically initiate a desirable mode (e.g., Sabbath-compliant state) from the determination.

[0058] In some embodiments, such as the example embodiments of FIG. 3, controller 190 includes a discrete primary controller 190A and secondary controller 190B operatively coupled to each other. Primary controller 190A may be generally configured to initiate or regulate various features of refrigerator appliance 100 while secondary controller 190B is configured to determine when a Sabbath condition occurs (e.g., when work-prohibiting Sabbath traditions must be followed). In some such embodiments, secondary controller 190B is programmed to include a preset Jewish calendar. During installation, a user may specify the initial time. A clock module (not shown) may be provided within controller 190 to maintain a current date and time once the initial time is specified. During installation, a user may further specify a geographic location (e.g., zip code, city and state, latitude and longitude, etc.) of the refrigerator appliance 100. Additionally or alternatively, the geographic location may be automatically determined [e.g., by a global positioning satellite unit (not pictured) within controller 190]. Once installed, secondary controller 190B may automatically track and determine when a Sabbath condition occurs along the Jewish calendar at the specified geographic location. For instance, secondary controller 190B may compare the current time to the preset Jewish calendar (e.g., continuously or at a predetermined interval). In some such embodiments, secondary controller 190B may include a communications module to receive information (e.g., from a remote server or website) regarding sunrise and sunset for the specified geographic location. Accordingly, secondary controller 190B may transmit a Sabbath condition signal to the primary controller 190A to indicate exactly when the Sabbath begins or ends.

[0059] In response to the determined Sabbath condition, controller 190 (e.g., primary controller 190A) may institute or enter into a Sabbath-compliant state. The Sabbath-compliant state may generally provide specific instructions or conditions for how various components of refrigerator appliance 100 may operate. For instance, the user interface panel 148 may be deactivated such that it is held in a constant non-responsive state. In turn, attempted user inputs will be ignored in the Sabbath-compliant state. Moreover, the user interface panel 148 may maintain an unlighted or singular display reading (e.g., “SAB”) to indicate or confirm the Sabbath-compliant state has been entered. Further, actuating mechanism 146 may be prevented from responsively delivering ice, as it would in a non-Sabbath-compliant state. Additionally or alternatively, door switch 182 may be deactivated during the Sabbath-compliant state such that opening / closing the corresponding door 128 has no effect on the internal light 184. In turn, internal light 184 may be maintained in a constant on or constant off state during the Sabbath-compliant state.

[0060] In some embodiments, the Sabbath-compliant state may limit the operation of the sealed cooling system 200, as shown in FIG. 5. For instance, a set cooling cycle may be provided for the compressor 202 in the Sabbath-compliant state. The cooling cycle generally includes a time span (e.g., in minutes) or a speed (e.g., as a percent between zero and one hundred percent) at which compressor 202 runs or operates. The compressor 202 may thus operate to compress or motivate the sealed refrigerant through the sealed cooling system 200 for the duration of the cooling cycle.

[0061] During the Sabbath-compliant state (e.g., while refrigerator appliance 100 remains in the Sabbath-compliant state), the cooling cycle may be repeated. For instance, the cooling cycle may be initiated along a set compressor interval. The set compressor interval may be defined as a repeating increment or unit of time (e.g., minutes) that is greater than the time span of the cooling cycle. Optionally, the set compressor interval may encompass a period wherein the compressor 202 is active (e.g., during the cooling cycle) and a period wherein the compressor 202 is not active. As the set compressor interval repeats, one individual compressor interval may follow another individual compressor interval. At the beginning or end of each individual interval, a new cooling cycle is initiated. In other words, the compressor 202 may be activated at least once at the beginning or end of each set compressor interval. Thus, the compressor interval may define a time pattern that the cooling cycle is repeated along. This pattern of may be repeated as long as refrigerator appliance 100 remains in the Sabbath-compliant state.

[0062] The time span of the cooling cycle may be fixed or, alternatively, variable in the Sabbath-compliant state. In embodiments wherein the time span is fixed, the compressor 202 will run or operate for the same amount of time during each new compressor interval. The time span may be predefined before assembly (e.g., according to gathered test data) or may be defined after installation. For instance, controller 190 may be configured to gather information regarding the run time of compressor 202 during non-Sabbath cooling cycles. In other words, controller 190 may detect one or more continuous operational run times of compressor 202 while refrigerator appliance 100 is in a non-Sabbath-compliant state. Specifically, controller 190 may detect and record how long compressor 202 is required to operate before entering the Sabbath-compliant state. In some such embodiments, the time span of the Sabbath-compliant state cooling cycle may be set according to the recorded continuous operational run time(s). As an example, the time span of the cooling cycle in the Sabbath-compliant state may be set as the most recent recorded continuous operational run time that has been detected during a non-Sabbath-compliant state. As another example, the time span of the Sabbath-compliant state cooling cycle may be set as an average of multiple recorded continuous operational run times that have been detected during a non-Sabbath-compliant state.

[0063] In embodiments wherein the time span is variable, the run time of the compressor 202 may vary between different compressor intervals. In other words, the compressor 202 may run for a first amount of time during one individual compressor interval, but run for a second (e.g., different) amount of time during another (e.g., subsequent) individual compressor interval. In some such embodiments, the time span of the cooling cycle is at least partially dependent on a detected temperature (e.g., a temperature detected at one or more of the temperature sensors 180). The detected temperature may be compared to a preset baseline temperature. If the detected temperature is greater than the preset baseline temperature, the time span of the cooling cycle may be increased. If the detected temperature is equal to or less than the preset baseline temperature may be left unchanged. In some embodiments, a temperature may be detected or gathered repeatedly. In other words a new detected temperature may be repeatedly compared to the preset baseline temperature. The detection may occur according to a predetermined pattern (e.g., of time). Alternatively, detection may occur according to a randomized time pattern or interval. As a randomized time pattern, the period between successive detections may vary such that occurrence of each detection cannot be predicted in advance. Advantageously, a user's actions are prevented from causing work to be done at the compressor 202 or refrigerator appliance 100.

[0064] In certain embodiments, the time span can be incrementally adjusted. Specifically, time may be added to an initial index or increment of time (e.g., a predetermined segment of time—e.g., in minutes) for the time span of the cooling cycle. In other words, an additional index of time is selectively added to an initial index of the time span for the cooling cycle. For instance, if the detected temperature exceeds a preset baseline temperature, an index of time may be added to an initial run time segment (e.g., the initial index or of the time span for the cooling cycle) such that the compressor 202 continues to operate until both the initial run time segment and the added index of time expire. As an example, the time span of the cooling cycle may be indexed based on a detected temperature within the refrigerated chamber 122 or 124. As another example, the time span of the cooling cycle may be indexed based on a detected temperature from the ambient environment. Optionally, multiple indexes of time may be added to a cooling cycle during the course of an individual compressor interval. Additionally or alternatively, multiple indexes are separated by periods of compressor inaction (e.g., during an individual compressor interval).

[0065] In some embodiments, the Sabbath-compliant state includes a deactivation period is required for each individual compressor interval. In other words, the controller 190 may require compressor 202 to maintain an inactive (e.g., non-compressing) state for at least a portion of each compressor interval. In turn, the deactivation period may generally define an amount of time during which compressor 202 must remain inactive. The deactivation period may be independent of the received temperature signal. Thus, if the controller 190 determines that the deactivation period has not been met during a current individual compressor interval (e.g., due to continuous operation of the compressor 202), the controller 190 may initiate the deactivation period. Advantageously, the refrigerator appliance 100 may ensure the sealed cooling system 200 does not freeze without requiring work from a user.

[0066] Turning now to FIG. 6, a flow chart is provided of method 300 according to example embodiments of the present disclosure. Generally, the method 300 provides processes or steps of operating a domestic appliance. The method 300 can be performed, for instance, by a controller of the domestic appliance. For example, the controller may be in operable communication with one or more components of the domestic appliance. As should be appreciated, the method 300 may also be applied to a group of domestic appliances. For example, the group of domestic appliances may include two or more domestic appliances, such as an oven appliance and a refrigerator appliance. The group of domestic appliances may include one or more controllers that may be in operable communication with one or more components of the group of domestic appliances.

[0067] FIG. 6 depicts steps performed in a particular order for purpose of illustration and discussion. Those of ordinary skill in the art, using the disclosures provided herein, will understand that (except as otherwise indicated) the steps of the methods disclosed herein can be modified, adapted, rearranged, omitted, or expanded in various ways without deviating from the scope of the present disclosure.

[0068] Many domestic appliances are shared by users that do observe the Sabbath (hereinafter “Sabbath observing users”) and users that do not observe the Sabbath (hereinafter “non-observing users”). Notably, embodiments of the present subject matter allow non-observing users of a shared domestic appliance to temporarily disable a Sabbath-compliant state of the domestic appliances during the Sabbath. Advantageously, methods within the scope of this disclosure may facilitate compliance with religious customs, such as Orthodox Jewish customs (e.g., while efficiently or effectively accounting for variations in a particular appliance unit or installed environment).

[0069] At 310, the method 300 includes determining an anticipated Sabbath condition (e.g., an upcoming Sabbath according to Jewish Law). Determining an anticipated Sabbath condition may include determining that a Sabbath (e.g., designated religious holiday or period of religiously-required rest) will soon begin. In some embodiments, a programmed calendar is referenced (e.g., within the controller) or a corresponding signal is received to indicate an upcoming or imminent Sabbath condition. In some other embodiments, determining the anticipated Sabbath condition includes determining the anticipated Sabbath condition automatically according to a preset geographic location for the domestic appliance. In some embodiments, the geographic location corresponds to the current physical location of the domestic appliance. Moreover, the geographic location may be automatically determined (e.g., by a global positioning satellite unit within the controller) or manually specified by a user (e.g., a zip code, city and state, latitude and longitude, or the like). Along with the geographic location, it is understood that determining a Sabbath condition includes monitoring the current time (e.g., as maintained at a clock within the controller) and comparing the current time to a programmed Jewish calendar. In turn, 310 may include determining a Sabbath start time and a Sabbath end time. At 310, the method 300 may further include comparing the current time to the determined Sabbath start and end times (e.g., continuously or at a predetermined interval). In some embodiments, 310 determining the Sabbath start time and the Sabbath end time is further based on sun data, such as a sunrise time and a sunset time (e.g., as received from a remote server or website).

[0070] Optionally, 310 may be performed prior to the actual start of the anticipated Sabbath condition. For instance, 310 may be performed at a predetermined amount of time (e.g., greater than or equal to 24 hours) prior to the start of the anticipated Sabbath. Thus, 310 may include determining the anticipated Sabbath will start within the predetermined time (e.g., in a day's time). In other words, 310 may include determining the predetermined time until the start of the Sabbath condition. In such embodiments, the domestic appliance may begin preparing for the Sabbath condition before the Sabbath actually starts (e.g., starting at the predetermined time, such as at least 24 hours in advance).

[0071] At 320, the method 300 includes directing the domestic appliance to a Sabbath-compliant state based on the anticipated Sabbath condition. For example, the method 300 may direct the domestic appliance to operate in the Sabbath-compliant state until the anticipated Sabbath condition expires. The parameters of the Sabbath-compliant state may be programmed by the manufacturer, set by the user, or determined and set in any other suitable manner. The Sabbath-compliant state is intended to allow the domestic appliance to be used by Sabbath observing users (e.g., users observing the Sabbath). The Sabbath-compliant state may be a state of the domestic appliance wherein usual, everyday operation of electrical components of the appliance are overridden to comply with Jewish Law. In this regard, directing the domestic appliance to the Sabbath-compliant state may include adjusting at least one operating parameter of the domestic appliance. As used herein “operating parameter” of a domestic appliance refers to any cycle setting, operating time, compressor speed, fan speed, part configuration, or other operating characteristics that may affect the performance of the domestic appliance. Thus, references to operating parameters adjustments or “adjusting at least one operating parameter” are intended to refer to control actions intended to affect system performance of the domestic appliance while honoring the Sabbath.

[0072] For example, when the domestic appliance is an oven appliance, adjusting at least one operating parameter of the domestic appliance may include disabling or shutting off an automatic shut off feature of the domestic appliance. The automatic shut off feature of the domestic appliance may be a feature that is intended to turn off heating elements of the oven appliance if they are left on for longer than a predetermined amount time. However, in the Sabbath-compliant state, the heating elements of the oven appliance may remain on throughout the day (e.g., such that the temperature of the cooking chamber is at or below a predetermined temperature threshold). For instance, in the Sabbath-compliant state power may be supplied to the heating elements without cutting off power to the domestic appliance in entirety.

[0073] As another example, when the domestic appliance is a refrigerator appliance, adjusting at least one operating parameter of the domestic appliance may include disabling lights, user interfaces, or other electrical elements that might otherwise be activated when (e.g., in response to) the refrigerator door is open. Moreover, when the domestic appliance is a refrigerator appliance, adjusting at least one operating parameter of the domestic appliance may include directing the compressor to operate on a predetermined timer so that opening the door, which typically results in the compressor turning on (e.g., due to a potential rise in temperature within the chilled chambers of the refrigerator), will have no immediate effect on the electrical operation of the appliance.

[0074] As should be appreciated, the above examples related to directing a domestic appliance in the Sabbath-compliant state are provided by way of example only and are not intended to limit the Sabbath-compliant state. In additional or alternative embodiments, the present subject matter may direct any suitable domestic appliance to the Sabbath-compliant state.

[0075] At 330, the method 300 includes receiving, at the domestic appliance, a non-observing signal at or during the Sabbath-compliant state following directing the domestic appliance to the Sabbath-compliant state. For instance, when the domestic appliance is directed to the Sabbath-compliant state or during the Sabbath compliant state, the non-observing signal may be received at the domestic appliance. Receiving the non-observing signal may include receiving from an external device associated with a non-observing user the non-observing signal. Specifically, the external device may be in operative communication with the domestic appliance. In this regard, the external device and the domestic appliance may be in communication such that the external device may transmit information or signals to the domestic appliance and the domestic appliance may be capable of transmitting information or signals (e.g., limited information or signals) to the external device. For example, the external device may transmit the non-observing signal to the domestic appliance and the domestic appliance may be capable of transmitting limited information, such as confirmation signals or messages to the external device.

[0076] The external device associated with the non-observing user may be any suitable remote device that is capable of transmitting a short-range wireless communication signal to the domestic appliance. For example, the external device may be smartphone, smartwatch, tablet, a short-range wireless communications module such as a Bluetooth® beacon, or the like. Communications may be transmitted from the external device using any suitable communications wireless devices or protocols, such as via Wi-Fi®, Bluetooth®, Zigbee®, wireless radio, or the like. In addition, such communication may use a variety of communication protocols (e.g., TCP / IP, HTTP, SMTP, FTP), encodings or formats (e.g., HTML, XML), or protection schemes (e.g., VPN, secure HTTP, SSL).

[0077] At 340, the method 300 includes temporarily directing the domestic appliance to a non-observing state at or during the Sabbath-compliant state of the domestic appliance in response to receiving the non-observing signal. For instance, when the domestic appliance is directed to the Sabbath-compliant state or during the, the domestic appliance may temporarily be directed to the non-observing state (e.g., in response to receiving the non-observing signal). The non-observing state being based on a non-observer condition. In some embodiments, the non-observer condition is determined prior to the start of the Sabbath. For example, determining the non-observer condition may include determining operating parameters of the domestic appliance that correspond to a non-observing user of the domestic appliance. Specifically, the non-observer condition of the domestic appliance may correspond to any suitable operating parameters of the domestic appliance. For instance, the non-observer condition may temporarily return or enable functionality (e.g., fully or partially) of the domestic appliance that was inhibited during the Sabbath-compliant condition. Advantageously, individuals who do not observe the Sabbath can easily and conveniently access functions and settings on shared appliances, without disrupting the Sabbath practices of those who do.

[0078] As should be appreciated, the non-observing state is “temporary” as it may last for only a limited period of time (e.g., during the Sabbath or at the Sabbath condition). Temporarily directing the domestic appliance to the non-observing state may include temporarily directing or adjusting one or more components of the domestic appliance according to a non-observer condition. The parameters of the non-observing state may be programmed by the manufacturer, set by the user, or determined and set in any other suitable manner. The non-observing state is intended to allow the domestic appliance to be used by a non-observing user during a religious holiday such as the Sabbath. In some embodiments, temporarily directing or adjusting one or more components of the domestic appliance includes temporarily permitting power to one or more elements of the domestic appliance. For example, heating elements, electrical components, user interfaces, fans, compressors, or any other suitable components of the domestic appliance may receive power such that operation of the domestic appliance may be temporarily returned to the non-observing state.

[0079] The method 300 may also include initiating an exit command following temporarily directing the domestic appliance to the non-observing state. Initiating the exit command may occur in response to a user initiated signal or activity being received or detected at the domestic appliance. In response to the exit command being initiating, the method 300 may direct the domestic appliance to return to the Sabbath-compliant state. In particular, directing the domestic appliance to return to the Sabbath-compliant state may be based on the anticipated Sabbath condition (e.g., as determined at 310). As mentioned above, the parameters of the Sabbath-compliant state may be programmed by the manufacturer, set by the user, or determined and set in any other suitable manner. In this regard, when the non-observing user is finished using the appliance (e.g., in response to the same), the method 300 may return to the Sabbath-compliant state.

[0080] In some embodiments, initiating the exit command includes detecting user activity at the domestic appliance. In some such embodiments, initiating the exit command also includes initiating a countdown timer in response to detecting the user activity. For instance, after a detectable user interaction (e.g., an interaction that may typically send a signal to a controller of the domestic appliance, such as interaction with a user interface, opening of a door, or any other suitable interaction) at the domestic appliance is detected, a countdown timer may be initiated. Further, in some such embodiments, initiating the exit command includes directing the domestic appliance to resume the Sabbath-compliant state following a timeout condition of the countdown timer being met. The timeout condition may be any suitable amount of time such as less than or equal to five minute, such as less than or equal to three minutes, such as less than or equal to one minute, such as less than or equal to thirty seconds. For example, if there is no user activity at the domestic appliance for a predetermined amount of time, the domestic appliance will return to the Sabbath-compliant state.

[0081] In some other embodiments, initiating the exit command includes receiving, from an external device, a user initiated exit command signal. For instance, after the non-observing user is done utilizing the domestic appliance, the non-observing user may transmit an exit command signal to the domestic appliance. The exit command signal may indicate that the non-observing user is done utilizing the domestic appliance in the non-observing state and that the domestic appliance is to be directed back to the Sabbath-compliant state. In some such embodiments, initiating the exit command also include directing the domestic appliance to resume the Sabbath-compliant state following receiving the user initiated exit command signal.

[0082] This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
