[0016] Figure 1 is a front view of a refrigerator 100 according to an example embodiment. Figure 2 is a perspective view of the refrigerator 100 . Figure 3 FIG. 1 is a front view of the refrigerator 100, showing the fresh food door 128 in an open state. The refrigerator 100 extends from the top 101 to the bottom 102 along a vertical direction V. The refrigerator 100 also extends from the first side 105 to the second side 106 along a lateral direction L. Figure 2 As shown, a transverse direction T may be further defined that is perpendicular to the vertical direction V and the transverse direction L. The refrigerator 100 extends along the transverse direction T from the front portion 108 to the rear portion 110 .

[0017] Refrigerator 100 may include a cabinet or housing 120 defining an upper fresh food compartment 122 (see Figure 3 ) and a lower freezer or frozen food storage chamber 124 located below the fresh food chamber 122 in a vertical direction V. An auxiliary food storage chamber may be located between the fresh food storage chamber 122 and the frozen food storage chamber 124, for example in the vertical direction V. Because the frozen food storage chamber 124 is located below the fresh food storage chamber 122, the refrigerator 100 may generally be referred to as a bottom-mounted refrigerator. In an exemplary embodiment, the housing 120 may also define a mechanical compartment (not shown) for accommodating a sealed cooling system (not shown). Using the teachings disclosed herein, those skilled in the art will understand that the present technology can be used with other types of refrigerators (e.g., side-to-side) or freezers. Therefore, the description provided herein is for illustrative purposes only and is not intended to limit the technology in any way.

[0018] The refrigerator doors 128 can each be rotatably hinged to an edge of the housing 120 to access the fresh food compartment 122. It should be noted that while two doors 128 in a "French door" configuration are shown, any suitable door arrangement using one, two, or more doors is within the scope and spirit of the present disclosure. A freezer door 130 can be arranged below the refrigerator door 128 to access the freezer compartment 124. In an exemplary embodiment, the freezer door 130 is coupled to a freezer drawer (not shown) that can be slidably mounted within the freezer compartment 124. An auxiliary door 127 may be coupled to an auxiliary drawer that can be slidably mounted within the auxiliary compartment.

[0019] The operation of the refrigerator 100 may be regulated by a controller 134 that is operatively connected to a user interface panel 136. The user interface panel 136 may provide options for a user to manipulate the operation of the refrigerator 100 to modify environmental conditions therein, such as temperature selections, etc. In some embodiments, the user interface panel 136 is adjacent to a dispensing assembly 132. In response to user manipulation of the user interface panel 136, the controller 134 may operate various components of the refrigerator 100. The operation of the refrigerator 100 may be regulated by the controller 134, for example, the controller 134 may regulate the operation of various components of the refrigerator 100 in response to programming and / or user manipulation of the user interface panel 136.

[0020] The controller 134 may include a memory and one or more microprocessors, CPUs or similar devices, such as general or special purpose microprocessors, operable to execute programming instructions or microcontrol codes associated with the operation of the refrigerator 100. The memory may represent a random access memory, such as a DRAM, or a read-only memory, such as a ROM or FLASH. In one embodiment, the processor executes programming instructions stored in the memory. The memory may be a component separate from the processor or may be built into the processor. It should be noted that the controller 134 disclosed herein is capable of and may be operated to perform any method and related method steps disclosed herein.

[0021] The controller 134 can be placed in multiple locations of the refrigerator 100. In the illustrated embodiment, the controller 134 is located within the door 128. In such an embodiment, input / output ("I / O") signals can be routed between the controller and the various operating components of the refrigerator 100. In one embodiment, the user interface panel 136 represents a general purpose I / O ("GPIO") device or functional block. In one embodiment, the user interface 136 includes an input component, such as one or more electrical, mechanical or electromechanical input devices, including knobs, buttons, and touch pads. The user interface 136 may include a display component, such as a digital or analog display device designed to provide operational feedback to the user. For example, the user interface 136 may include a touch screen that provides input and display functions. The user interface 136 may communicate with the controller via one or more signal lines or a shared communication bus.

[0022] Using the teachings disclosed herein, those skilled in the art will appreciate that the present subject matter can be used with other types of refrigerators such as refrigerator / freezer combinations, side-by-side, bottom mount, compact, and any other style or model of refrigerator. Thus, other configurations of refrigerator 100 can be provided, and it should be understood that the configurations shown in the drawings and the descriptions provided herein are for exemplary and illustrative purposes only.

[0023] In some embodiments, for example, Figure 4 As shown, refrigerator 100 includes a water filter 200 connected thereto. For example, water filter 200 may be connected to a water supply line (not shown) such that water filter 200 receives a stream of water 1000, such as raw water or unfiltered water, from the water supply line and provides filtered water 1002 to portions of the water supply line downstream of filter 200 and / or to various fixtures or components of refrigerator 100 (e.g., an ice maker, a water dispenser, etc.). Water filter 200 may include a housing or body 202 defining a liquid receiving space 201, wherein an inlet 204 opens through housing 202 to liquid receiving space 201, and an outlet 208 exits from liquid receiving space 201. As shown in FIG. Figure 4 As shown, unfiltered water 1000 can flow into the filter 200 through the inlet 204. The water may then flow through a filter medium 206, such as a membrane, activated carbon or other suitable filter medium, including a combination of multiple media, to produce filtered water 1002, which is discharged from the water filter 200 through an outlet 208. In other or alternative embodiments, the filter medium 206 may include one or more filter electrodes (e.g., anodes, cathodes, etc.) that receive current to filter the water. One or more electrodes may be located in the liquid receiving space 201. For example, the filter electrode can perform a deionization reaction in the water to remove impurities. As described below, the power provided to the filter electrode may be wirelessly transmitted to the water filter 200 by the refrigerator 100.

[0024] The body 202 may define an electronic component room 203. In detail, the electronic component room 203 may be fluidically separated from the liquid receiving space 201. Figure 4 Schematically, the electronic component room 203 can be formed at a location adjacent to the body 202 and the liquid receiving space 201. Thus, a portion of the body 202 can be located between the liquid receiving space 201 and the electronic component room 203. Additionally or alternatively, the body 202 can define a top, a bottom, opposite sides, and an outward radial portion. Thus, it can be said that the electronic component room 203 is located within the housing of the water filter 200 (e.g., as defined by the body 202).

[0025] One or more electronic components may be disposed (e.g., positioned) within the electronic component room 203. Thus, these electronic components (described below) may be fluidically isolated from the liquid receiving space 201 and, thereby, isolated from the water flow received within the liquid receiving space 201. Thus, the electronic component room 203 may be defined as an electronic receiving space. In some cases, the electronic component room 203 may be selectively accessed (e.g., by a user). For example, a waterproof access door may be provided on the body 202 of the water filter 200 to access the electronic component room 203. According to other embodiments, the electronic component room 203 is sealed relative to the liquid receiving space 201 and the ambient atmosphere.

[0026] Figures 5 to 7 A schematic representation of a water filter (e.g., water filter 200) and a refrigerator (e.g., refrigerator 100) is provided. In some embodiments, a wireless power transmitter 312 is provided for powering one or more electronic devices within refrigerator 100. In particular, wireless power transmitter 312 can be mounted on or within cabinet 120, in operable communication (e.g., wireless or contactless communication) with water filter 200, transmitting an electromagnetic field thereto, which may subsequently power one or more electronic components. For example, wireless power transmitter 312 can transmit an electromagnetic field to an antenna (described below) located within electronic component room 203.

[0027] As shown, the wireless power transmitter 312 may be physically separated from the water filter 200 by a certain distance at a discrete part of the refrigerator 100 (e.g., the docking port of the water filter 200). When assembled, the wireless power transmitter 312 may therefore be wirelessly coupled to the water filter 200 (e.g., never in direct or conductive contact with the water filter). Furthermore, an air gap may be maintained between the two. For example, the electronic component room 203 of the water filter 200 may be electrically sealed so that no wires or buses pass through the body 202. For example, when the water filter 200 is installed in the refrigerator 100, there will be no direct physical contact between the components in the electronic component room 203 and the wireless power transmitter 312. Advantageously, this can avoid potential failure or leakage points while still allowing power to be supplied to one or more electronic components in the water filter 200.

[0028] In addition or alternatively, the wireless power transmitter 312 can operate (e.g., transmit an electromagnetic field) in accordance with one of a variety of protocols. These protocols may include, for example, a near field communication (NFC) protocol, a Xi protocol, a radio frequency identification (RFID) protocol, a laser protocol, a microwave protocol, etc. It should be understood that the list of potential protocols is not exhaustive and any suitable wireless protocol can be used. For example, among a variety of protocols, the wireless power transmitter 312 may transmit a power charging signal (e.g., for wireless charging of electronic components), a wireless authentication signal (e.g., confirming that the water filter 200 has the ability to receive wireless charging), a data transmission signal (e.g., a wireless signal including data related to the components of the water filter 200), etc.

[0029] refer to Figures 5 to 7 , an antenna 210 may be provided within the water filter 200. In particular, the antenna 210 may be embedded within the housing 202 of the water filter 200. For example, in some embodiments, the antenna 210 is located within the electronic component room 203. The antenna 210 may be configured to receive an electromagnetic field 212 (e.g., transmitted by a wireless power transmitter 312 within the refrigerator 100). Thus, the antenna 210 may be configured to receive an electromagnetic field (e.g., by operating a protocol of the wireless power transmitter 312) according to a relevant protocol, as is understood by people.

[0030] The received electromagnetic field 212 can be converted into a usable signal by the power harvesting circuit 214. In detail, the power harvesting circuit 214 can be disposed in the electronic component room 203. The power harvesting circuit 214 can be electronically connected to the antenna 210. Therefore, the electromagnetic field 212 can be transmitted to the power harvesting circuit 214 through one or more electrical connections. The power harvesting circuit 214 can then generate a current or voltage and transmit the current or voltage to the onboard controller. According to some embodiments, the onboard controller is integrated with the power harvesting circuit 214. However, a separate, dedicated controller may be included in the water filter 200 (e.g., in the electronic component room 203).

[0031] Typically, the wireless power transmitter 312 and the antenna 210 may be configured to exchange electromagnetic fields that generate an electric current. For example, the wireless power transmitter 312 may transmit an electromagnetic field (e.g., initiated by the controller 134), which is received at the antenna 210 (also referred to as a wireless power receiver). At the antenna 210, a current or voltage may be generated and then transmitted to the onboard controller (e.g., through an onboard rectification circuit or activation circuit). For example, the electromagnetic field may induce a current at the power harvesting circuit 214, which may be received by the onboard controller (e.g., within the power harvesting circuit). During operation, the onboard controller may be powered by the power harvesting circuit 214.

[0032] As will be appreciated, the wireless power transmitter 312 and the power harvesting circuit 214 may be a pair of resonant induction coils. However, it should be appreciated that any other suitable wireless power transfer method (eg, inductive coupling, capacitive coupling, etc.) may be used.

[0033] As described above, the water filter 200 may include one or more electronic components 216. Specifically, these electronic components 216 may include light emitting diodes (LEDs), electrodes (e.g., filter electrodes for ionizing water), electrode life sensors (e.g., for determining the remaining life or efficiency of the electrodes), water volume sensors, water circulation sensors, etc. For example, the electrode life sensor may include a voltage sensor on the electrode, a water quality sensor next to the electrode, a chemical reaction sensor, etc. These electronic components can be operatively coupled to the power harvesting circuit 214 (e.g., via a positive and negative voltage connection). Therefore, the current or voltage generated by the power harvesting circuit 214 can be transmitted to the one or more electronic components 216 to power them. In addition or alternatively, one or more electronic components 216 may include a battery (e.g., a rechargeable battery). For example, the power harvesting circuit 214 may have a built-in battery. Therefore, the electrical signal or voltage can be stored in the battery to power the one or more electronic components 216 at a selected time.

[0034] refer to Figure 6According to some embodiments, the water filter 200 may include multiple antennas. For example, the water filter 200 may include a first antenna 210 and a second antenna 211. The first antenna 210 and the second antenna 211 may be located at different locations within the electronic component room 203. For example, the first antenna 210 may be disposed in a first portion of the electronic component room 203, and the second antenna 211 may be disposed in a second portion of the electronic component room 203 relative to the first portion. In addition or alternatively, the first antenna 210 may be electrically connected to the power harvesting circuit 214. The second antenna 211 may also be selectively electrically connected to the power harvesting circuit 214. For example, the first antenna 210 and the second antenna 211 may be respectively connected to the power harvesting circuit 214 (e.g., respectively provide or receive current to or from the power harvesting circuit 214). As described below, the first antenna 210 and the second antenna 211 may operate according to different protocols, and thus perform different functions in terms of the power harvesting circuit 214.

[0035] The first antenna 210 may be configured to receive the first electromagnetic field 212. The first electromagnetic field 212 may be transmitted by the first wireless power transmitter 312 according to the first protocol. As described above, wireless communication between the refrigerator 100 and the water filter 200 (e.g., via the first antenna 210 or the second antenna 211) may be established and performed using a variety of protocols. Therefore, the water filter 200 may be configured to support multi-protocol communication through multiple antennas. For example, the second antenna 211 may be configured to receive the second electromagnetic field 213. The second electromagnetic field 213 may be transmitted by the second wireless power transmitter 313 according to the second protocol. The second protocol may be different from the first protocol. Therefore, when the first antenna 210 operates according to the first protocol and the second antenna 211 operates according to the second protocol, the first antenna 210 and the second antenna 211 may be located adjacent to each other in the electronic component room 203. Advantageously, the volume of the electronic component room 203 may be relatively small, increasing the volume of the liquid receiving space 201, allowing more water to be filtered in a shorter time.

[0036] According to some embodiments, the second antenna 211 is coupled to a wireless authentication module 217. Specifically, the one or more electronic components 216 may include a wireless authentication module 217 for confirming the wireless capability of the water filter 200. As described above, the second antenna 211 may be configured to receive the second electromagnetic field 213 according to a second protocol (e.g., different from the first protocol 212 of the first antenna 210). According to some embodiments, the controller 134 of the refrigerator 100 may determine that the water filter 200 has the ability to receive wireless power through communication with the second antenna 211. Advantageously, the refrigerator 100 can avoid unnecessary emission of the electromagnetic field 212 (e.g., when authentication is not confirmed), thereby saving energy and reducing the operating costs of the refrigerator 100.

[0037] Reference Figure 7 According to another embodiment, the water filter 200 may include an information bus 218. The information bus 218 may provide a connection through which data can be transmitted between one or more electronic components 216. For example, the second antenna 211 operates according to a third protocol that allows wireless information transmission between the water filter 200 (e.g., the electronic components thereon) and the refrigerator 100. Data about one or more electronic components (e.g., filter life, water volume, etc.) can be transmitted from the first electronic component 216 via the information bus 218. Then, the data or information can be transmitted to the refrigerator 100 via the second antenna 211 (e.g., via the second electromagnetic field 213) according to the third protocol.

[0038] According to other embodiments, the water filter 200 (e.g., within the electronic component room 203) may implement three or more antennas. Each antenna may be configured to operate according to a unique protocol to avoid electromagnetic interference. For example, the first antenna may establish wireless authentication of the water filter, the second antenna may allow power transmission from the refrigerator 100 to the water filter 200, and the third antenna may allow data transmission (e.g., regarding one or more electronic components 216 between the water filter 200 and the refrigerator 100).

[0039] This written description uses examples to disclose the invention, including the best mode, and also to enable any skilled person 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 differ from the literal language of the claims, or if they include equivalent structural elements with insignificant differences from the literal language of the claims.
