    [0020] Referring now to the figures, FIGS. 1 and 2 provide perspective views of a refrigerator appliance (e.g., refrigerator appliance 100) according to an exemplary embodiment of the present disclosure. As shown, refrigerator appliance 100 includes a cabinet or housing 102 that extends between a top 104 and a bottom 106 along a vertical direction V, between a first side 108 and a second side 110 along a lateral direction, and between a front 112 and a back 114 along a transverse direction T. Housing 102 may define one or more chilled chambers for receipt of food items for storage. In some embodiments, housing 102 defines fresh food chamber 122 positioned at or adjacent top 104 of the housing 102 and a freezer chamber 124 arranged at or adjacent bottom 106 of housing 102. As such, refrigerator appliance 100 may generally be referred to as a bottom mount refrigerator.

    [0021] It is recognized, however, that the benefits of the present disclosure apply to other types and styles of refrigerator appliances such as, for example, a top mount refrigerator appliance, a side-by-side style refrigerator appliance or a standalone icemaker 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 refrigerator chamber configuration.

    [0022] Refrigerator doors 128 may be rotatably hinged to an edge of housing 102 for selectively accessing fresh food chamber 122. In addition, a freezer door 130 may be arranged below refrigerator doors 128 for selectively accessing freezer chamber 124. Freezer door 130 may be coupled to a freezer drawer (not shown) slidably mounted within freezer chamber 124. Refrigerator doors 128 and freezer door 130 are shown in the closed configuration in FIG. 1.

    [0023] In some embodiments, various storage components are mounted within fresh food chamber 122 to facilitate storage of food items therein, as would be understood. In particular, the storage components may include storage bins 116, drawers 118, and shelves 120 that are mounted within fresh food chamber 122. As such, storage bins 116, drawers 118, and shelves 120 are configured for receipt of food items (e.g., beverages or solid food items) and may assist with organizing such food items. As an example, drawers 118 may receive fresh food items (e.g., vegetables, fruits, or cheeses) and increase the useful life of such fresh food items.

    [0024] In some embodiments, refrigerator appliance 100 also includes a dispensing assembly 140 for dispensing liquid water or ice. Dispensing assembly 140 may include a dispenser 142, for example, positioned on or mounted to an exterior portion of refrigerator appliance 100 (e.g., on one of doors 128). Moreover, as shown in FIG. 1, dispenser 142 may include a discharging outlet 144 for accessing ice and liquid water. Further, an actuating mechanism 146, shown as a paddle, may be mounted below discharging outlet 144 for operating dispenser 142. In alternative embodiments, any suitable actuating mechanism may be used to operate dispenser 142. A user interface panel 148 may also be provided for controlling the mode of operation. For example, user interface panel 148 may include 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.

    [0025] Still referring to FIG. 1, discharging outlet 144 and actuating mechanism 146 may be an external part of dispenser 142 and may be mounted in a dispenser recess 150. Dispenser recess 150 may be 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 additional embodiments, dispenser recess 150 is positioned at a level that approximates the chest level of a user.

    [0026] In further embodiments, as shown in FIG. 2, refrigerator appliance 100 may include a sub-compartment 162 defined on refrigerator door 128. Sub-compartment 162 may be referred to as an icebox. Further, as shown, sub-compartment 162 extends into fresh food chamber 122 when refrigerator door 128 is in the closed position. Although sub-compartment 162 is shown in door 128, additional or alterative embodiments may include sub-compartment 162 fixed within fresh food chamber 122. In an embodiment, an ice maker and/or an ice storage bin (not shown) may be positioned or disposed within sub-compartment 162. Accordingly, during use, ice may be supplied to dispenser recess 150 (FIG. 1) from the ice making assembly or ice storage bin in sub-compartment 162 on a back side of refrigerator door 128.

    [0027] In additional or alternative embodiments, chilled air from a sealed system (not shown) of refrigerator appliance 100 may be directed into components within sub-compartment 162. For instance, sub-compartment 162 may receive cooling air from a chilled air supply duct 165 and a chilled air return duct 167 (FIG. 2) disposed on a side portion of cabinet 102 of refrigerator appliance 100. In this manner, supply duct 165 and return duct 167 may recirculate chilled air from a suitable sealed cooling system through sub-compartment 162.

    [0028] In optional embodiments, as shown in FIG. 2, an access door 166 may be hinged to refrigerator door 128. Thus, access door 166 may permit selective access to sub-compartment 162. Any manner of suitable latch 168 may be configured with sub-compartment 162 to maintain access door 166 in a closed position. As an example, latch 168 may be actuated by a user in order to open access door 166 to provide access into sub-compartment 162. Access door 166 may also assist with insulating sub-compartment 162 (e.g., by thermally isolating or insulating sub-compartment 162 from fresh food chamber 122). It is noted that although access door 166 is illustrated in exemplary embodiments, alternative embodiments may be free of any separate access door.

    [0029] Referring particularly to FIG. 3, operation of refrigerator appliance 100 may generally be controlled by a processing device or controller 176. Controller 176 may, for example, be operatively coupled to control panel 148 for user manipulation to select features and operations of refrigerator appliance 100, such as temperature set points. Thus, controller 176 may operate various components of refrigerator appliance 100 to execute selected system cycles, processes, and/or features. In exemplary embodiments, controller 176 is in operative communication (e.g., electrical or wireless communication) with each of the chambers or compartments therein, for example, to regulate temperature as described herein.

    [0030] More specifically, as shown in FIG. 3, a block diagram of one embodiment of suitable components that may be included within controller 176 in accordance with example aspects of the present disclosure is illustrated. As shown, controller 176 may include one or more processor(s) 178, computer, or other suitable processing unit and associated memory device(s) 180 that may include suitable computer-readable instructions that, when implemented, configure the controller to perform various different functions, such as receiving, transmitting and/or executing signals (e.g., performing the methods, steps, calculations and the like disclosed herein).

    [0031] As used herein, the term processor refers not only to integrated circuits referred to in the art as being included in a computer, but also refers to a controller, a microcontroller, a microcomputer, a programmable logic controller (PLC), an application specific integrated circuit, and other programmable circuits. Additionally, memory device(s) 180 may generally include memory element(s) including, but not limited to, computer readable medium (e.g., random access memory (RAM)), computer readable non-volatile medium (e.g., a flash memory), a floppy disk, a compact disc-read only memory (CD-ROM), a magneto-optical disk (MOD), a digital versatile disc (DVD) and/or other suitable memory elements.

    [0032] Such memory device(s) 180 may generally be configured to store suitable computer-readable instructions that, when implemented by processor(s) 178, configure the controller to perform various functions as described herein. Additionally, controller 176 may also include a communications module 182 to facilitate communications between the controller and the various components of refrigerator appliance 100. An interface can include one or more circuits, terminals, pins, contacts, conductors, or other components for sending and receiving control signals. Moreover, controller 176 may include a sensor interface 184 (e.g., one or more analog-to-digital converters) to permit signals transmitted from temperature probe(s) 210 described herein to be converted into signals that can be understood and processed by processor(s) 178.

    [0033] As mentioned, refrigerator appliance 100 may include at least one sensor 200. The at least one sensor 200 may be positioned within cabinet 102 of appliance 100. For instance, the at least one sensor 200 may include a first temperature sensor or probe 210 and a second temperature sensor or probe 220. First temperature sensor 210 may be positioned within fresh food chamber or compartment 122 and second temperature sensor 220 may be positioned within freezer chamber or compartment 124. Thus, as would be understood, each of first temperature sensor 210 and second temperature sensor 220 may be configured to sense, measure, monitor, or otherwise determine a temperature within each of fresh food chamber 122 and freezer chamber 124, respectively. Additionally or alternatively, three or more sensors may be included as certain embodiments warrant, such as for additional chambers or compartments (e.g., an ice storage compartment, an ice maker, a beverage compartment, a drawer, etc.).

    [0034] As used herein, temperature sensor or the equivalent is intended to refer to any suitable type of temperature measuring system or device positioned at any suitable location for measuring the desired temperature. Thus, for example, first temperature sensor 210 or second temperature sensor 220 may be or include any suitable type of temperature sensor, such as a thermistor, a thermocouple, a resistance temperature detector, a semiconductor-based integrated circuit temperature sensor, etc. In addition, first temperature sensor 210 or second temperature sensor 220 may be positioned at any suitable location and may output a signal, such as a voltage, to a controller (e.g., controller 176) that is proportional to or indicative of the temperature being measured. Although exemplary positioning of temperature sensors is described herein, it should be appreciated that appliance 100 may include any other suitable number, type, and position of temperature or other sensors according to alternative embodiments.

    [0035] FIG. 4 schematically illustrates refrigerator appliance 100 communicating with a remote user interface device 1000. Also shown (but not numbered) in FIG. 4 is a user such as may interact with the remote user interface device 1000, e.g., via a user interface 1002 of the remote user interface such as a touchscreen in the illustrated embodiment. For example, the remote user interface device 1000 may be a device such as a cell phone, smart phone, smart assistant, or any similar device in operative communication with controller 176 via a wireless connection. As shown in FIG. 4, refrigerator appliance 100, and in particular, controller 176 thereof, may be configured to communicate with a separate device external to appliance 100, such as a communications device or other remote user interface device 1000. Remote user interface device 1000 may be a laptop computer, smartphone, tablet, personal computer, wearable device, smart home system (such as a smart assistant speaker), or various other suitable devices. Refrigerator appliance 100 may include a network communication module, e.g., a wireless communication module, for communicating with the remote user interface device 1000. In various embodiments, a network communication module may include a network interface such that controller 176 of refrigerator appliance 100 can connect to and communicate over one or more networks with one or more network nodes. A network communication module may also include one or more transmitting, receiving, or transceiving components for transmitting/receiving communications with other devices communicatively coupled with refrigerator appliance 100. The network communication module may be in communication with, e.g., coupled or connected to, controller 176 to transmit signals to and receive signals from controller 176.

    [0036] As schematically illustrated in FIG. 4, refrigerator appliance 100 may be configured to communicate with the remote user interface device 1000 either directly or through a network 2000 (e.g., a smart home network). Thus, in various embodiments, refrigerator appliance 100 and remote user interface 1000 may be configured to communicate wirelessly with each other or with network 2000. Network 2000 may be or include various possible communication connections and interfaces, e.g., such as Zigbee, BLUETOOTH, WI-FI, or any other suitable communication connection. The remote user interface device 1000 may include a memory for storing and retrieving programming instructions. For example, the remote user interface device 1000 may be a smartphone operable to store and run applications, also known as apps, and may include a remote user interface provided as a smartphone app. Additionally or alternatively, multiple remote user interface devices 1000 may be connected with refrigerator appliance 100. For instance, one or more smart phones, one or more smart assistant devices (smart speakers), or the like may be simultaneously connected with refrigerator appliance 100 (e.g., through network 2000).

    [0037] Now that the general descriptions of an exemplary appliance have been described in detail, a method 300 of operating an appliance (e.g., refrigerator appliance 100) will be described in detail. Although the discussion below refers to the exemplary method 300 of operating refrigerator appliance 100, one skilled in the art will appreciate that the exemplary method 300 is applicable to any suitable domestic appliance capable of performing a cooling operation (e.g., such as a freezer, an icemaker, etc.). In exemplary embodiments, the various method steps as disclosed herein may be performed by controller 176 and/or a separate, dedicated controller. FIG. 5 provides a flow chart illustrating a method of operating a refrigerator appliance. Hereinafter, method 300 will be described with specific reference to FIG. 5.

    [0038] At step 302, method 300 may include determining the refrigerator appliance is operating according to a predetermined operating mode. For instance, a controller (e.g., controller 176) may determine that the appliance (e.g., refrigerator appliance 100) has been placed into a specific operating mode. A user may adjust one or more control programs or operational parameters of the appliance according to a requested mode. According to at least some embodiments, the predetermined operating mode is a vacation mode. The vacation mode may be indicative of an extended period of time for which the appliance may be idle, unused, or otherwise unmanipulated. Accordingly, the vacation mode may assume that doors (e.g., refrigerator doors 128, freezer door 130, etc.) may not be opened while the appliance is in the predetermined (vacation) mode. Thus, during the predetermined (vacation) mode, one or more of the doors of the appliance are maintained in the closed position, such that chambers (e.g., fresh food chamber 122, freezer chamber 124) are sealed.

    [0039] As mentioned above, the appliance may be remotely connected with a network (e.g., cloud) with which information may be shared regarding operational parameters of the appliance. For instance, the appliance may periodically send signals to the cloud or remote network including, e.g., temperature signals, power signals, alerts, images, or the like. In some instances, method 300 may include detecting a loss of communication between the appliance (e.g., refrigerator appliance) and the remote network after determining the refrigerator is in the predetermined operating mode (vacation mode). The remote network (e.g., cloud) may determine that no signals are being received from the appliance when one or more sampling events are missed (e.g., relating to information sent from the appliance to the remote network).

    [0040] Method 300 may thus further include determining a duration of the loss of communication between the appliance and the remote network. For instance, the remote network may resume a connection with the appliance after a predetermined down time or dark time. After resuming the connection, method 300 may calculate, estimate, or otherwise determine the length of the down time. The length or duration of the loss of communication (down time) may be stored, e.g., temporarily within the remote network or on the appliance, such as within a memory (e.g., memory device 180). Additionally or alternatively, certain information (e.g., metadata) may be stored relating to the down time, such as a day, month, year, time of day, or the like. The data and metadata may be packaged together into a notification or alert, described below.

    [0041] At step 304, method 300 may include receiving a temperature signal from the at least one sensor after determining the refrigerator appliance is operating according to the predetermine operating mode. In detail, after the appliance is confirmed to be operating according to the predetermined mode (e.g., vacation mode), the at least one sensor (e.g., first temperature sensor 210, second temperature sensor 220) may measure the temperature within one of the chambers (e.g., fresh food chamber 122, freezer chamber 124, etc.) at predetermined intervals. The predetermined intervals may be set according to a schedule. For instance, the at least one sensor may send temperature signals at sampling events or time frames that are spaced apart (e.g., equally). Additionally or alternatively, the at least one sensor may be transmit the sensed temperature according to a predetermined trigger.

    [0042] According to some embodiments, method 300 may include determining that a predetermined length of time has elapsed since a most recent defrost phase. For instance, after receiving the temperature signal, method 300 may compare the time at which the temperature signal was obtained against a defrost phase. In detail, the appliance may regularly perform defrost phases or operations to remove frost buildup from certain parts of the appliance (e.g., evaporator coils, sidewalls, etc.). As would be understood, during the defrost phases, a temperature within the cabinet (e.g., within the fresh food chamber or the freezer chamber) may temporarily increase. Accordingly, temperature signals obtained within the predetermined length of time since a most recent defrost phase may be ignored or flagged as an anticipated temperature rise.

    [0043] Additionally or alternatively, as mentioned above, method 300 may determine that the appliance has been disconnected (e.g., remotely) from the remote network for a certain length of time. Upon reestablishing the connection, the temperature signal may be obtained and transmitted to the controller (e.g., either on board the appliance or at the remote network). The temperature signal may be analyzed within a predetermined time frame from reestablishing the connection.

    [0044] At step 306, method 300 may include determining that the temperature signal is above a predetermined temperature threshold. In detail, while the appliance is operating according to the predetermined operation mode (e.g., vacation mode), temperature fluctuations may be predictable due to the doors remaining in the closed position. Accordingly, abnormally high temperatures may be flagged. Each temperature signal obtained by the at least one sensor and transmitted to the controller may be analyzed against the predetermined temperature threshold. As mentioned above, at step 308, method 300 may include determining that the temperature signal is received outside of a defrost phase. Accordingly, those temperature signals at or near the most recent defrost period (e.g., within the predetermined length of time) may be ignored as anticipated and within a normal operating range. Any temperature signal above the predetermined temperature threshold and outside of the defrost phase may be flagged and stored (e.g., within the memory).

    [0045] At step 310, method 300 may include emitting an alert in response to determining that the temperature signal is outside of the defrost phase and the value of the temperature signal is above the predetermined temperature threshold. The alert may include the value of the temperature signal (e.g., in degrees Fahrenheit, degrees Celsius, etc.) and a date on which the temperature signal was received or obtained. As mentioned above, the appliance may remain in the predetermined operating (vacation) mode for an extended period of time, such as days, weeks, months, etc. The alert may thus include a timestamp of the temperature signal along with the value. The alert (or notification) may be emitted to one or more communications devices. For instance, the alert may be emitted or transmitted to a user interface of the appliance (e.g., a display or display screen), a remote user device (e.g., mobile phone, smartphone, etc.), a connected smart appliance (e.g., smart speaker, kitchen hub, etc.), or the like. For instance, the alert may be presented to a user via a mobile app (e.g., a push notification), a text message, an email, or the like.

    [0046] According to some instances, the alert may include the duration of the loss of communication between the appliance and the remote network (e.g., the down time). For instance, in the event the loss of communication or outage was detected or determined, the alert may include information related to the outage, including a date stamp, a length of time, and the temperature detected immediately after reestablishing communication. Further, the alert may include general information related to items within the appliance. For instance, the alert may include guidance, tips, or the like pertaining to temperatures at which certain food items may be considered spoiled, unhealthy, dangerous, or the like.

    [0047] 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.
