Description

Technical Field

[0001] This invention relates generally to refrigeration appliances, and more specifically to lighting systems for refrigeration appliances. Background Technology

[0002] Refrigeration appliances typically include a housing that defines a refrigerated compartment for receiving and storing food. Additionally, the appliance includes one or more doors that are rotatably hinged to the housing to allow selective access to the food stored in the refrigerated compartment. The appliance may also include various storage components installed within the refrigerated compartment and designed to facilitate food storage therein. These storage components may include shelves, boxes, racks, or drawers that receive food within the refrigerated compartment and aid in the organization and arrangement of such food.

[0003] Furthermore, traditional refrigeration appliances include lighting systems that illuminate the refrigeration compartment. However, these traditional lighting systems are designed solely to improve visibility within the compartment. In this respect, these traditional lighting systems are passively operated; for example, the lighting system activates when a door switch indicates it is open and deactivates when a door switch indicates it is closed. Moreover, traditional lighting systems lack versatility and the ability to convey information about the operation of the appliances. Even when the lighting system is powered on, it operates with a single, uniform intensity and color throughout the refrigeration compartment.

[0004] Therefore, refrigeration appliances with improved lighting systems would be useful. More specifically, lighting systems for refrigeration appliances that offer general lighting configurations, improved aesthetics, and a richer user experience would be particularly beneficial. Summary of the Invention

[0005] Various aspects and advantages of the invention will be set forth in the description which follows, or will be apparent from the description, or may be learned by practicing the invention.

The controller is configured to receive a command to adjust the temperature in a selected zone among the plurality of cooling zones, adjust the operation of the climate control system to adjust the temperature in the selected zone, identify a selected lighting zone among the plurality of lighting zones corresponding to the selected zone, and illuminate the selected lighting zone to provide feedback on the operation of the climate control system.

[0007] In another exemplary embodiment, a method of operating a refrigeration appliance is provided. The refrigeration appliance includes: a refrigeration chamber defining a plurality of cooling zones; a climate control system for selectively providing cooling airflow to the plurality of cooling zones; and an illumination assembly including a plurality of illumination zones corresponding to the plurality of cooling zones.

[0022] Referring now to embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. Each example is given by way of explanation and does not constitute a limitation thereof. Indeed, it will be apparent to those skilled in the art that various modifications and variations can be made to the invention without departing from its scope or spirit. For example, features shown or described as part of one embodiment can be used in another embodiment, thereby producing yet another embodiment. Therefore, it is desired that the invention cover such modifications and variations falling within the scope of the appended claims and their equivalents.

[0023] As used herein, the terms “first,” “second,” and “third” are used interchangeably to distinguish one component from another, and these terms are not intended to indicate the location or importance of individual components. The terms “upstream” and “downstream” refer to the relative direction of fluid flow within a fluid pathway. For example, “upstream” refers to the direction from which the fluid flow originates, while “downstream” refers to the direction to which the fluid flow terminates. The terms “includes” and “including” are intended to be included in a manner similar to the term “comprising.” Similarly, the term “or” is generally intended to be included (i.e., “A or B” is intended to mean “A or B or both”).

[0024] As used herein throughout the specification and claims, approximate language is applied to modify any quantitative representation that may vary without altering its associated essential function. Therefore, values ​​modified by terms such as “approximately,” “about,” and “roughly” are not limited to the specified precise values. In at least some cases, approximate language may correspond to the precision of the instrument used to measure the value. For example, approximate language may refer to a margin of 10%.

[0025] Figure 1 A perspective view of a refrigeration appliance 100 according to an exemplary embodiment of the present invention is provided. The refrigeration appliance 100 includes a housing or enclosure 102 extending along a vertical direction V between a top 104 and a bottom 106, along a lateral direction L between a first side 108 and a second side 110, and along a transverse direction T between a front side 112 and a rear side 114. Each of the vertical direction V, the lateral direction L, and the transverse direction T is perpendicular to each other and forms an orthogonal direction system.

[0026] The cabinet 102 defines a refrigeration compartment for receiving and storing food. Specifically, the cabinet 102 defines a food preservation compartment 122 disposed at or adjacent to the top 104 of the cabinet 102 and a freezer compartment 124 disposed at or adjacent to the bottom 106 of the cabinet 102. Thus, the refrigeration appliance 100 is generally referred to as a bottom-mounted refrigerator. However, it is understood that the benefits of the invention are applicable to other types and styles of refrigeration appliances, such as top-mounted refrigeration appliances, side-by-side refrigeration appliances, or single-door refrigeration appliances. Furthermore, aspects of the invention can also be applied to other appliances, such as those including fluid dispensers. Therefore, the description set forth herein is for illustrative purposes only and is not intended to limit any particular appliance or configuration in any way.

[0027] The refrigerator door 128 is rotatably hinged to the edge of the cabinet 102 for selective access to the food preservation compartment 122. Additionally, a freezer door 130 is arranged below the refrigerator door 128 for selective access to the freezer compartment 124. The freezer door 130 is coupled to a freezer drawer (not shown) that is slidably mounted within the freezer compartment 124. To prevent cold air leakage, one or more sealing mechanisms (e.g., rubber gaskets, not shown) may be defined at the interfaces where the doors 128, 130 meet the cabinet 102. It should be understood that doors with different styles, positions, or constructions are possible within the scope of this invention.

[0028] Figure 2 A perspective view of the refrigeration appliance 100 is provided with the refrigerator door 128 in the open position. (See diagram below.) Figure 2 As shown, as those skilled in the art will understand, various storage components are installed within the food preservation compartment 122 to facilitate the storage of food therein. In particular, the storage components may include boxes 134 and shelves 136. Each of these storage components is used to receive food (e.g., beverages or / or solid foods) and may assist in the organization of such food. As shown, box 134 may be mounted on the refrigerator door 128 or may slide into the receiving space within the food preservation compartment 122. It should be understood that the storage components shown are for illustrative purposes only, and other storage components may be used, and these other storage components may have different sizes, shapes, and constructions.

[0029] See you again Figure 1 This document describes a dispensing component 140 according to an exemplary embodiment of the invention. While several different exemplary embodiments of the dispensing component 140 will be illustrated and described, similar reference numerals may be used to refer to similar parts and features. The dispensing component 140 is generally used for dispensing liquid water and / or ice. Although an exemplary dispensing component 140 has been illustrated and described herein, it should be understood that various changes and modifications can be made to the dispensing component 140 while remaining within the scope of the invention.

[0030] The dispensing assembly 140 and its various components may be at least partially disposed within a dispenser recess 142 defined on a refrigerator door 128. In this respect, the dispenser recess 142 is defined on the front side 112 of the refrigeration appliance 100, allowing the user to operate the dispensing assembly 140 without opening the refrigerator door 128. Furthermore, the dispenser recess 142 is positioned at a predetermined height that facilitates ice retrieval by the user and allows the user to retrieve ice without bending over. In an exemplary embodiment, the dispenser recess 142 is positioned approximately at chest level with the user.

[0031] Dispensing assembly 140 includes an ice dispenser 144 with a discharge port 146 for discharging ice from the dispensing assembly 140. An actuation mechanism 148, shown as a lever, is mounted below the discharge port 146 to operate the ice or water dispenser 144. In an alternative exemplary embodiment, any suitable actuation mechanism can be used to operate the ice dispenser 144. For example, the ice dispenser 144 may include a sensor (such as an ultrasonic sensor) or a button instead of a lever. The discharge port 146 and the actuation mechanism 148 are external parts of the ice dispenser 144 and are mounted in the dispenser recess 142. In contrast, the refrigerator door 128 may define an ice box chamber 150 that houses an ice maker and ice storage boxes (not shown). Figure 2 The ice maker and ice storage box are configured to supply ice to the dispenser recess 142.

[0032] Control panel 152 is configured to control operating modes. For example, control panel 152 includes one or more selection inputs 154, such as knobs, buttons, touchscreen interfaces, etc., such as water dispensing buttons and ice dispensing buttons, for selecting a desired operating mode, such as crushed ice or non-crushed ice. Additionally, selection input 154 can be used to specify the filling volume or the method of operating dispensing component 140. In this respect, selection input 154 can communicate with the processing device or controller 156. Signals generated in controller 156 operate refrigeration appliance 100 and dispensing component 140 in response to selection input 154. Furthermore, a display 158, such as indicator lights or a screen, can be provided on control panel 152. Display 158 can communicate with controller 156 and can display information in response to signals from controller 156.

[0033] As used herein, "processing device" or "controller" can refer to one or more microprocessors or semiconductor devices, and is not necessarily limited to a single element. The processing device can be programmed to operate the refrigeration appliance 100, the dispensing assembly 140, and other components of the refrigeration appliance 100. The processing device may include or be associated with one or more storage elements (e.g., permanent storage media). In some such embodiments, the storage element includes an electrically erasable programmable read-only memory (EEPROM). Typically, the storage element may store information accessible to the processing device, including instructions that can be executed by the processing device. Optionally, the instructions may be software or any set of instructions and / or data that, when executed by the processing device, causes the processing device to perform operations.

[0034] See again briefly. Figure 1According to an exemplary embodiment, housing 102 also defines a mechanical chamber 170 at or near its bottom 106 for housing a hermetically sealed cooling system 172. Typically, the sealed cooling system 172 is used to transfer heat from the interior of the refrigeration appliance 100 to the exterior (e.g., by performing a vapor compression cycle or another suitable refrigeration cycle). As commonly understood by those skilled in the art, the sealed cooling system 172 contains a working fluid (e.g., a refrigerant) that flows between various heat exchangers in the sealed cooling system 172, where the working fluid undergoes a phase change while transferring heat energy.

[0035] In this respect, such as Figure 5 As best shown, the hermetically sealed cooling system 172 may include a compressor 174, a condenser 176, an expansion device 178, and one or more evaporators 180, which are connected in series via fluid conduits filled with refrigerant. Within the hermetically sealed cooling system 172, refrigerant flows into the compressor 174, which operates to increase the pressure of the refrigerant. This compression of the refrigerant raises its temperature, which is lowered by passing the refrigerant through the condenser 176. Within the condenser 176, heat exchange with the surrounding air occurs to cool the refrigerant. A condenser fan 182 may be used to blow air across the condenser 176 to provide forced convection for faster and more efficient heat exchange between the refrigerant within the condenser 176 and the surrounding air. Thus, as those skilled in the art will know, increasing the airflow through the condenser 176 can, for example, improve the efficiency of the condenser 176 by improving the cooling of the refrigerant contained therein.

[0036] An expansion device 178 (e.g., an electronic expansion valve, capillary tube, or other limiting device) receives refrigerant from the condenser 176. The refrigerant then flows from the expansion device 178 into the evaporator 180. As it leaves the expansion device 178 and enters the evaporator 180, the refrigerant pressure decreases. Due to the pressure drop and / or phase change of the refrigerant, the evaporator 180 is relatively cool. An evaporator fan 184 is typically located at each evaporator 180, for example, to force air across and around at least one evaporator 180, thereby transferring heat from the air to the evaporator 180 (and more specifically, to the working fluid or refrigerant therein).

[0037] Thus, a cooling airflow (generally identified herein by reference numeral 186) exits the evaporator 180 and can be distributed to one or more of the cooling chambers 122 and / or 124. Specifically, one or more conduits may extend between the machine room 170 and the cooling chambers 122 and / or 124 to provide fluid communication between them, for example, to supply cool air 186 from the hermetically sealed, hermetically sealed cooling system 172 (e.g., from its evaporator 180) to one or more of the cooling chambers 122 and / or 124.

[0038] The hermetically sealed cooling system 172 depicted and described herein is provided by way of example only. Therefore, other configurations using the refrigeration system are also within the scope of this invention. For example, according to alternative embodiments, the hermetically sealed cooling system 172 may include additional components, such as at least one additional evaporator, compressor, expander, and / or condenser. For example, the refrigeration appliance 100 may have two or more separate evaporators, such as one primarily dedicated to cooling the food preservation compartment 122 and one primarily dedicated to cooling the freezer compartment 124. Additionally, optional piping system configurations, valves, and flow regulators may be used to route the refrigerant throughout the hermetically sealed cooling system 172.

[0039] In some embodiments, the refrigeration appliance 100 also includes one or more sensors 172 that can be used to facilitate improved operation of the refrigeration appliance 100, as described below. For example, to obtain temperature measurements within one or more refrigerated compartments 122, 124 (or areas / zones within refrigerated compartments 122, 124), the refrigeration appliance 100 may include multiple temperature sensors (generally identified herein by reference numeral 190). A controller 156 may be communicatively coupled to the temperature sensors 190, may receive signals from these temperature sensors 190 corresponding to the temperature of the atmosphere or air at their respective locations, and may implement responsive actions, for example, by directing more or less cooling air 186 toward the area or compartment.

[0040] As used herein, "temperature sensor" or equivalent is intended to refer to any suitable type of temperature measurement system or device positioned in any suitable location for measuring a desired temperature. Thus, for example, temperature sensor 190 can be any suitable type of temperature sensor, such as a thermistor, thermocouple, resistance temperature detector, etc. Furthermore, temperature sensor 190 can be positioned in any suitable location and can output a signal, such as a voltage, to the controller that is proportional to and / or indicates the temperature of the air surrounding temperature sensor 190. Although exemplary arrangements of temperature sensors are described and exemplified herein, it should be understood that, according to alternative embodiments, refrigeration appliance 100 may include any other suitable number, type, and location of temperature and / or other sensors.

[0041] Now generally refer to Figures 3 to 10 This section will describe a climate control system 200 that can be used with a refrigeration appliance 100 according to an exemplary embodiment of the present invention. In this regard, for example, the climate control system 200 may typically include a hermetically sealed cooling system (such as hermetically sealed cooling system 172) for selectively regulating the temperature within the food preservation compartment 122, the freezer compartment 124, or the temperature in a specific area within each of these compartments 122, 124. Specifically, as Figure 3and Figure 5 As best shown, the food preservation compartment 122 typically defines seven zones, within which the temperature can be independently regulated by the climate control system 200.

[0042] Specifically, these zones are identified in the accompanying drawings as Zone 201, Zone 202, Zone 203, Zone 204, Zone 205, Zone 206, and Zone 207. In this regard, for example, Zones 201, 202, and 203 may be primary storage zones, including or partially defined by shelves 136 for supporting food. Additionally, Zone 204 may be a convertible drawer or a cooked food storage drawer. Zones 205, 206, and 207 may be positioned near the bottom of the food preservation compartment 122 and may include preservation drawers or other product storage drawers. It should be understood that the zone configurations described herein are merely exemplary and not intended to limit the scope of the invention in any way. Although the climate control system 200 is described herein as being for selectively regulating the temperature within each of zones 201-207, it should be understood that the refrigeration appliance 100 may include any other suitable number and configuration of zones while remaining within the scope of the invention.

[0043] Typically, the climate control system 200 can independently regulate the temperature within each zone 201-207 by adjusting the temperature and flow rate of the cooling airflow 186 received by each zone 201-207. For example, according to an exemplary embodiment, the temperature of the cooling airflow 186 can be adjusted by regulating the operation of the sealed cooling system 172. Additionally, the refrigeration appliance 100 may also include a flow regulation component 210 for selectively redirecting or regulating the cooling airflow 186 through the refrigeration appliance 100.

[0044] In this respect, the flow regulation assembly 210 may include any suitable number and type of flow regulation devices, such as fans, air handlers, blowers, dampers, control valves, etc. Additionally, the flow regulation assembly 210 may include any suitable number of ducts or duct system configurations for guiding the cooling airflow 186 through the housing 102 as needed. Although an exemplary flow regulation assembly 210 will be described below with reference to exemplary embodiments, it should be understood that variations and modifications can be made to the flow regulation assembly 210 and the climate control system 200 while remaining within the scope of the invention.

[0045] See now for details. Figure 5The image illustrates a portion of the inner liner within the housing 102, revealing aspects, components, and features of the flow control assembly 210. Specifically, as illustrated, the flow control assembly 210 typically includes an air distribution tower 212, which is generally used to direct cooling airflow 186 to each of the respective cooling zones 201-207. According to an exemplary embodiment of the invention, in Figure 6 A schematic diagram of a climate control system 200, including a sealed cooling system 172 and a flow regulation component 210, is provided.

[0046] As illustrated in the figure, air distribution tower 212 typically includes or defines one or more supply air ducts 214 and one or more return air ducts 216, which are fluidly connected to the hermetically sealed cooling system 172 and each of the various zones 201-207. See details. Figure 6 Air distribution tower 212 defines a single supply air duct 214 and a single return air duct 216 for each of zones 201-203, for a total of six ducts. Each of these supply air ducts 214 and return air ducts 216 extends from its respective zone to a central air chamber 218 through which cooling airflow 186 is introduced into air distribution tower 212.

[0047] In this respect, the cooling airflow 186 can exit the evaporator 180 of the sealed cooling system 172 and enter the central air chamber 218. From the central air chamber 218, the flow regulation assembly 210 can typically guide the cooling airflow 186 through the food preservation compartment 122 (e.g., through one or more zones 201-207). To receive supply air and feedback return air, each zone 201-203 may include a supply port 220 fluidly connected to a corresponding supply air duct 214 and a return port 222 fluidly connected to a corresponding return air duct 216. Thus, for example, as Figure 6 As shown in the example implementation, the cooling airflow 186 can pass upward through the air distribution tower 212 before entering the zones 201-203 from the left side of the air distribution tower 212 and returning towards the sealing system 172 from the right side of the air distribution tower 212 via the return port 222.

[0048] Although each of zones 201-203 is exemplified as having dedicated supply and return ports 220, 222, it should be understood that, according to the exemplary embodiment, zones 204-207 of the fourth to seventh grades may include only the supply port 220 and may not include dedicated return ports. For example, according to the exemplified embodiment, each of zones 204-207 includes only the supply port 220 for providing cooling airflow 186 therein. It is worth noting that a closed-loop airflow can be achieved as the cooling airflow 186 passes through a gap in or around the storage box 134 before returning to the central air chamber 218 via a main return device (not shown) or via the return port 222 associated with zones 201-203. Other flow configurations are possible and are within the scope of the invention.

[0049] See now for details. Figures 6 to 10 The flow regulation assembly 210 may also include one or more damper assemblies 230 operatively coupled to the air distribution tower 212, the central air chamber 218, or other supply and return air ducts for selectively guiding the cooling airflow 186 through the refrigeration appliance 100 into zones 201-207. In this respect, according to an exemplary embodiment, a pivoting damper 232 is operatively coupled to each of the supply air duct 214 and the return air duct 216 to regulate the cooling airflow 186 through the air distribution tower 212. Thus, each damper 232 can pivot independently between an open position allowing the cooling airflow 186 through a corresponding supply port 220 or return port 222 and a closed position preventing the cooling airflow 186 from passing through. Additionally, it should be understood that the damper 232 may be positioned in an intermediate position, for example, to partially restrict airflow.

[0050] As exemplified in an exemplary embodiment, damper assembly 230 includes a drive mechanism 234, which typically includes a motor and / or transmission assembly 236 for rotating drive shaft 238. A plurality of mechanical actuators 240 are mounted along drive shaft 238, which selectively and independently push dampers 232 to an open position. For example, according to the exemplified embodiment, each damper 232 may be spring-loaded toward a closed position and actuated toward an open position when a protrusion 242 on the respective mechanical actuator 240 engages a cam actuator 244 defined on the damper 232. According to an exemplary embodiment of the invention, controller 156 can be used to selectively and independently open and / or close each damper 232 to regulate the precise flow rate of cooling airflow 186 entering or returning from each respective zone 201-207.

[0051] Now briefly see Figure 9 and Figure 10Zones 204-207 may also include damper assemblies 230 for regulating the flow of cooling air 186 therethrough. According to an exemplary embodiment, these damper assemblies 230 operate in the same manner as described above. For example, as... Figure 9 As shown, the storage box 134 includes a supply port 220 defined near the rear side of the storage box 134. This rear side of the storage box 134 may directly abut a central air chamber 218, which may define an orifice (not shown) covered by a box damper 250. In this respect, the box damper 250 may function in the same or similar manner as the damper 232 to regulate the cooling airflow 186 into the storage box 134. As described above, the air may be returned via an air distribution tower 212 or via another return air duct defined behind the storage box 134.

[0052] See you again Figures 3 to 5 This section will describe an illumination assembly 260 that can be used with a cooling appliance 100 according to an exemplary embodiment of the present invention. Specifically, as briefly explained above, the illumination assembly 260 is generally designed to provide an improved user experience of the cooling appliance 100 by, for example, providing the user with visual feedback on the flow of cooling air through the cooling appliance 100. Additionally, the illumination assembly 260 can be used to indicate when specific zones 201-207 have reached their setpoint temperature to identify flow restrictions or other operational problems, or to provide any other useful information to the user of the cooling appliance 100.

[0053] Specifically, according to an exemplary embodiment, the lighting assembly 260 typically includes a plurality of light sources 262 disposed throughout the food preservation compartment 122. Specifically, each of these light sources 262 may be positioned or oriented toward a plurality of lighting zones 264. These lighting zones 264 may correspond to a plurality of cooling zones 201-207. In this respect, each of the cooling zones 201-207 includes one or more light sources 262, which can operate as independent light zones, for example, isolating and illuminating that particular zone to attract or focus the user's attention.

[0054] According to an exemplary embodiment, it may be desirable to identify the location of the supply port 220 and / or return port 222, for example, to help users avoid placing food in locations that might obstruct these ports 220, 222. For example, to inform the user of the location of the supply port 220 and return port 222 in each of zones 201-203, a light source 262 may be disposed above or adjacent to at least one of the supply ports 220 and 222. Alternatively, the light source 262 may be disposed in any other suitable portion of zones 201-203. Additionally, each of zones 204-207 may also include a dedicated light source 262 disposed therein for selectively illuminating each of the respective storage compartments 134.

[0055] As used herein, the term "light source" and the like can generally be used to refer to any suitable light source used to illuminate the refrigeration appliance 100 in any suitable manner. For example, light source 262 may include any suitable number, type, location, and configuration of electric light sources, using any suitable optical technology and illuminating in any suitable color. For example, according to the illustrated embodiment, light source 262 includes one or more light-emitting diodes (LEDs), which may each illuminate in a single color (e.g., white LEDs) or each illuminate in multiple colors (e.g., multi-color or RGB LEDs), depending on the control signal from controller 156. However, it should be understood that, according to alternative embodiments, light source 262 may include any other suitable conventional bulbs or light sources, such as halogen bulbs, fluorescent bulbs, incandescent bulbs, light bars, fiber optic light sources, etc. Additionally, it should be understood that the refrigeration appliance 100 may include additional lighting, such as general chamber lighting that can illuminate the entire food preservation compartment 122 and / or freezer compartment 124.

[0056] It is worth noting that the controller 156 can be used to operate the lighting assembly 260 to provide useful information to consumers or users of the cooling appliance 100. In this respect, for example, it is useful for users of the cooling appliance 100 to know when the cooling airflow 186 is provided and which zones 201-207 it travels through. In this respect, according to an exemplary embodiment, the light source 262 can be illuminated in these zones where the cooling airflow 186 is currently being directed, for example, based at least in part on the setting of the damper assembly 230.

[0057] Furthermore, it should be understood that the lighting effects generated by the lighting component 260 can be adjusted to indicate different operating conditions or identify specific situations. For example, the light source 262 can flash to indicate that air is being directed to specific zones 201-207. Additionally, the light source 262 can become constant when specific zones 201-207 reach a setpoint temperature. In this respect, for example, the light source 262 can flash as the specific zone is cooled, but once the setpoint is reached, the temperature can become constant. Thereafter, the light source 262 can maintain a constant intensity until the temperature within the corresponding zone 201-207 drops below or above a predetermined temperature range from the setpoint, such as ±3°F, ±5°F, or any other suitable temperature range. It should be understood that other variations of the light source 262 can be used to provide useful information to the user, such as changes in color, intensity, sequence, flashing rhythm, or any other suitable variation.

[0058] According to other embodiments, the light source 262 can notify the user when airflow restriction occurs. For example, if a user places a gallon of milk directly in front of the supply port 220 or return port 222, the climate control system 200 may no longer be able to cool the corresponding zone to the setpoint temperature. For example, the controller 156 can detect such airflow restriction by monitoring the temperature in the restricted zones 201-207. If the temperature in the restricted zone does not reach the setpoint temperature within a predetermined amount of time, the controller 156 can infer that airflow in that particular zone 201-207 is restricted and can provide the user with a notification of the restriction. Specifically, when the controller 156 detects a restriction, the light source 262 and the corresponding zone 201-207 can flash rapidly, turn red, or illuminate with any other color or intensity to notify the user of the airflow restriction.

[0059] It is worth noting that, according to the exemplary embodiment, the setpoint temperature of each zone 201-207 can be set by the user of the refrigeration appliance 100. For example, the user can input the setpoint temperature using the control panel 152 or using a remote device (such as a mobile phone running a software application) communicatively connected to the controller 156. However, according to other embodiments, such as Figure 3 and Figure 4 For example, the refrigeration appliance 100 may include or operate a temperature control module 280, which may be selectively located in one of a plurality of zones 201-207. The temperature control module 280 is operable and configured to communicate, for example, wirelessly with a controller 156. The controller 156 may locate the temperature control module 280, for example, determining which zone of the plurality of zones 201-207 the temperature control module 280 is located in or placed in, and then the controller 156 may adjust the operation of the refrigeration appliance 100 (e.g., climate control system 200) to regulate the temperature in the zone where the temperature control module 280 is located based on a temperature setting received by the controller 156 from the temperature control module 280.

[0060] In some embodiments, the temperature control module 280 may include a user interface 282 (e.g., a touchscreen interface) for receiving input from a user, such as temperature settings, and / or for providing information to the user, such as displaying visual indicators and / or temperature readings or settings. In some embodiments, the temperature control module 280 may also, or alternatively, receive user input from a remote user interface device (such as a personal computer, smartphone, tablet, smart home system, or other similar device). For example, the remote user interface device may be a smartphone and may run an application or "app," whereby the remote user interface device can receive temperature settings in the application and then wirelessly transmit the temperature settings to the temperature control module 280.

[0061] In some embodiments, the refrigeration appliance 100 may include one or more wireless receivers (not shown), such as antennas, coupled to the controller 156 for sending and receiving signals to and from the controller 156 and the temperature control module 280. For example, the controller 156 may wirelessly communicate with the temperature control module 280 via one or more antennas. In embodiments including more than one wireless receiver, the controller 156 may be used to locate the temperature control module 280 based on wireless signals received from the temperature control module 280 via more than one wireless receiver. For example, the controller 156 may be used to locate the temperature control module 280 by triangulation of the received wireless signals using multiple wireless receivers.

[0062] According to an exemplary embodiment, the refrigeration appliance 100 may also include, or alternatively include, a plurality of mating ports (not shown) corresponding to each of zones 201-207. For example, each mating port may be located in one of the zones 201-207, and each of the zones 201-207 may have one mating port. The mating ports may each be configured (e.g., sized and shaped) to receive a temperature control module 280 therein. For example, the temperature control module 280 may be generally disk-shaped, such as a cylinder with a diameter several times larger than its longitudinal axis (e.g., two or three times larger). In this embodiment, the mating port may be a shallow cylindrical recess within each zone 201-207, such that the temperature control module 280 can be partially nested within the corresponding mating port of the zone where the temperature control module 280 is located.

[0063] Furthermore, each docking port may include a mechanical switch (not shown) that contacts the temperature control module 280 when the temperature control module 280 is located within the docking port. Thus, the controller 156 can be configured to locate the temperature control module 280 based on a signal received from the mechanical switch when the temperature control module 280 actuates the mechanical switch in the corresponding docking port.

[0064] Now that the structure and configuration of the refrigeration appliance 100, climate control system 200, and lighting assembly 260 according to an exemplary embodiment of the invention have been presented, an exemplary method 300 for operating the climate control system and lighting assembly in the refrigeration appliance is provided. Method 300 can be used to operate the climate control system 200 and lighting assembly 260, or to operate any other climate control and lighting assembly. In this regard, for example, a controller 156 can be used to implement method 300. However, it should be understood that the exemplary method 300 is discussed herein only to describe exemplary aspects of the invention and is not intended to be limiting.

[0065] like Figure 11As shown, method 300 includes, in step 310, receiving a command to adjust the temperature in a selected zone among a plurality of cooling zones within the refrigeration appliance. At this point, a command can be received from a user to adjust a specific zone (e.g., one or more of zones 201-207) to a specific setpoint temperature. According to an exemplary embodiment, the command can be received from a user, from a remote device (such as a mobile phone), or from a temperature control module 280 via a selection input 154 through a control panel 152. If a setpoint temperature is received from the temperature control module 280, step 310 may further include, for example, identifying the zone where the temperature control module 280 is located in the manner described above, and adjusting the temperature in the zone corresponding to that location. It is noteworthy that, as described above, the various zones 201-207 of the food preservation compartment 122 can be commanded to operate at different setpoint temperatures.

[0066] Step 320 includes adjusting the operation of the climate control system to regulate the temperature within a selected zone, for example, by directing a cooling airflow into the selected zone. In this regard, for example, the climate control system may operate the sealed cooling system 172 to generate a cooling airflow 186, and may use the flow regulating assembly 210 and / or the damper assembly 230 to independently separate and direct the cooling airflow 186 into each of zones 201-207 to independently control the temperature within each zone 201-207. It is noteworthy that, as described above, it may be desirable to provide the user with information about the operation of the climate control system, such as where the cooling airflow 186 is directed.

[0067] Therefore, step 330 may include identifying a selected lighting area among a plurality of lighting areas of the lighting assembly that corresponds to the selected area. In this regard, as explained above with reference to an exemplary embodiment, the lighting assembly 260 may have a plurality of light sources 262 disposed in lighting areas 264 corresponding to areas 201-207. When the selected areas 201-207 (e.g., as selected in steps 310 and 320) have a temperature regulated by the climate control system 200, the light sources 262 in the corresponding lighting areas 264 may be illuminated to provide useful information about the operation of the cooling appliance 100.

[0068] Specifically, step 340 may include illuminating a selected lighting area to provide feedback on the operation of the climate control system, such as providing visual feedback on the cooling airflow. Thus, once a setpoint is reached and the climate control system 200 begins pumping cooling airflow 186 toward a specific area, the light source 262 corresponding to that area may begin to flash to notify the user that the specific area is being actively cooled. Similarly, once the area approaches or reaches the setpoint temperature, the lighting effect may change, for example, by changing the solid color. If the temperature within the area falls outside the range around the setpoint temperature, the lighting area 264 may implement another lighting effect, such as flashing, changing color, etc.

[0069] According to other embodiments, method 300 may include: in step 350, detecting an airflow restriction that limits cooling airflow to a restricted area among a plurality of cooling zones. For example, the airflow restriction may be detected by determining that a particular zone has not reached its setpoint temperature after a predetermined amount of time. The predetermined amount of time may be selected in any suitable manner or determined by controller 156 as the average amount of time required for the zone to reach its setpoint temperature, the time spent adjusting the zone to a predetermined degree, etc.

[0070] Step 360 may include operating the lighting components to provide user notification of airflow limitation. In this regard, when controller 156 determines, for example, that an airflow limitation exists based on the inability to reach a setpoint temperature, controller 156 may implement a lighting sequence to draw the user's attention to the fact that an airflow limitation exists. According to an exemplary embodiment, controller 156 may predict precisely which supply port 220 or return port 222 has experienced a limitation and may cause the light source 262 positioned above the respective port 220, 222 to flash. According to other embodiments, controller 156 may illuminate all light sources 262 within the restricted area in pure red, thereby indicating an airflow limitation or another problem with the climate control system 200.

[0071] Figure 11 An exemplary control method having steps performed in a specific order for illustrative and discussion purposes is described. Those skilled in the art will understand, using the inventive content provided herein, that the steps of any method described herein can be adapted, rearranged, extended, omitted, or modified in various ways without departing from the scope of the invention. Furthermore, while aspects of the method are illustrated using a refrigeration appliance 100, a climate control system 200, and a lighting assembly 260 as examples, it should be understood that these methods can be applied to the operation of any suitable appliance, climate control system, and / or lighting assembly.

[0072] This invention provides a refrigerator lighting system with a sequence of lighting effects to provide visual feedback based on the operation of a sealed refrigeration system, a flow control system, or the overall airflow within the refrigeration appliance. For example, a refrigerator controller is operatively coupled to the refrigerator lighting system to illuminate the lighting effect sequence based on the state of the airflow system and user commands. This decorative lighting feedback system enhances the perception of product performance, user experience, and appliance quality.

[0073] According to an exemplary embodiment, when a user places food in a specific zone and selects the associated zone temperature, the refrigerator lighting system can illuminate that zone in a specific order, color, or intensity to highlight the zone and provide visual feedback to the user. According to an exemplary embodiment, the lighting sequence, color, or other characteristics may vary, for example, based on the temperature of the airflow, the zone temperature relative to a setpoint temperature, or both.

[0074] For example, when a sealed refrigeration system or flow control device delivers cold air, the light in a specific zone may flash, indicating that the product is operating and the chamber is approaching the temperature setpoint. Furthermore, lighting-based feedback (e.g., via flashing, selective color, etc.) can be used to indicate whether the temperature in that specific zone has reached the user-set temperature. For example, flashing or color can indicate that the zone is not yet at the set temperature, but a steady change in light or color can indicate that the zone is at the user-set temperature, or within a range around the set temperature. Thus, the user can visually identify the airflow conditions in each specific zone and throughout the entire refrigeration appliance.

[0075] According to other embodiments, the refrigerator lighting system can be used to warn the user when the airflow path is blocked and prevents proper operation. Furthermore, the refrigerator lighting system can be used in conjunction with a separate temperature controller (e.g., using a separate temperature control module or temperature control disc) to provide feedback to the user in the area controlled by the temperature control module.

The patentable scope of the invention is defined by the claims and may include other examples that may be conceived by those skilled in the art. Such other examples are expected to fall within the scope of the claims if they include structural elements that are not distinct from the literal language of the claims, or if they include equivalent structural elements that are not substantially distinct from the literal language of the claims.
