This application relates generally to a refrigerator appliance door, and more particularly, an appliance door including an endcap at a distal edge thereof, wherein a wireless module is disposed on the endcap, and wherein the wireless module is configured to wirelessly communicate with a mobile device.
Conventional appliances, including refrigeration appliances, can be connected to a remote computer server, often referred to as a ‘cloud server’ or simply the ‘cloud,’ which is then connected to a remote mobile device to thereby provide electronic data communication and control capabilities between an end user and the refrigerator appliance from remote locations of the end user. The refrigerator appliance is generally connected to the ‘cloud’ via a wireless module. Conventionally, such wireless modules are positioned within a cabinet of the refrigerator appliance or even on an external surface of the cabinet.
Placing the wireless module within the cabinet generally results in smaller possible connective ranges for wireless data transmission and reception due to the various obstructions surrounding the wireless module. Moreover, such placement can make installation or repair servicing of the wireless module difficult, as various elements must be removed (by specific tools) before gaining access to the wireless module. Additionally, because the cabinet is typically made of metal, placing the wireless module within the cabinet, or even on an external surface thereof diminishes wireless data transmission and reception connectivity.
In accordance with one aspect, there is provided a refrigerator appliance door comprising an outer skin extending between first and second distal edges thereof. The outer skin forms an external appearance of the refrigerator appliance door. An inner liner is disposed adjacent the outer skin such that a space is formed therebetween. A first endcap is disposed at the first distal edge of the outer skin. The first endcap partially encloses the space formed between the outer skin and the inner liner. The refrigerator appliance door further includes a wireless module configured to wirelessly communicate with a mobile device. The wireless module is positioned on the first endcap.
In accordance with another aspect, there is provided an appliance comprising a cabinet defining a compartment for storing food items in a cooled environment. A door is pivotably attached to the cabinet to provide selective access to the compartment. The door comprises an endcap disposed adjacent a top wall of the cabinet when the door is in a closed position. The door further includes a wireless module configured to wirelessly communicate with a mobile device. The wireless module is positioned on the endcap and includes a printed circuit board and an antenna. The antenna faces outwards and away from the endcap.

The cover comprises a top wall that is coplanar with the top wall of the first endcap. The cover has a securing clip extending outwards from the top wall thereof. The securing clip is configured to engage with a corresponding tab protruding from the peripheral wall of the first pocket in order to secure the cover to the first endcap.
Referring now to the drawings,
Two fresh-food compartment doors 108 shown in
A center flip mullion 112 (shown in
As shown in
The fresh-food compartment 102 serves to minimize spoiling of articles of food stored therein. This is accomplished by maintaining the temperature in the fresh-food compartment 102 at a cool temperature that is typically above 0° C., so as not to freeze the articles of food in the fresh-food compartment 102. It is contemplated that the cool temperature is a user-selectable target fresh-food temperature preferably between 0° C. and 10° C., more preferably between 0° C. and 5° C. and even more preferably between 0.25° C. and 4.5° C. A fresh-food evaporator (not shown) is dedicated to separately maintaining the temperature within the fresh-food compartment 102 independent of the freezer compartment 106.
As best shown in
A control unit or user interface 128 is disposed on an upper portion of the door 124. The user interface 128 is positioned such that it is not visible when the VCZ drawer assembly 120 is in a closed position (as shown in
As further shown in
The freezer compartment 106 is used to freeze and/or maintain articles of food stored therein in a frozen condition. For this purpose, the freezer compartment 106 includes a freezer evaporator (not shown) that removes thermal energy from the freezer compartment 106 to maintain the temperature therein at a user-selectable target freezer temperature, e.g., a temperature of 0° C. or less during operation of the refrigerator 100, preferably between 0° C. and −50° C., more preferably between 0° C. and −30° C. and even more preferably between 0° C. and −20° C. The freezer compartment 106 is also in communication with the VCZ compartment 104 such that a portion of the cooling air supplied by the freezer evaporator (not shown) may be selectively supplied to the VCZ compartment 104.

As shown, the fresh-food compartment door 108 comprises an outer skin 200, an inner liner 300, a first (top) endcap 400, a second (bottom) endcap 500, a cover 600, and a wireless module 700. The outer skin 200 is a plate-like member, bent to form an external appearance of the fresh-food compartment door 108. The outer skin 200 includes a front panel 202 and opposing side panels 204 extending (rearwardly) away therefrom. The front panel 202 and the side panels 204 can all be formed integrally (i.e., from a single material, such as metal) during a single manufacturing process to form a planar, plate-like member, wherein the side panels 204 are subsequently bent away from the front panel 202. However, it is contemplated that the front panel 202 and the side panels 204 can be formed separate and distinct from one another and subsequently secured together.
The outer skin 200 extends between a first (top) distal edge 206 and a second (bottom) distal edge 208. The distance between the first distal edge 206 and the second distal edge 208 of the outer skin 200 is equal to or greater than a corresponding vertical distance of the cabinet opening providing access into the fresh-food compartment 102. That is, the first distal edge 206 of the outer skin 200 is generally disposed adjacent a top wall of the cabinet 110 (shown in
The inner liner 300 is sized and shaped to be received by respective edges of the side panels 204 of the outer skin 200. That is, in an installed position, the inner liner 300 extends generally parallel to the front panel 202 such that the inner liner 300 extends (in a vertical direction) between the first and second distal edges 206, 208, and is spaced from the front panel 202 via the side panels 204. Accordingly, when the inner liner 300 is secured to the outer skin 200, a space is formed therebetween. Typically, the inner liner 300 is made of a molded plastic material.
The inner liner 300 faces the fresh-food compartment 102 when the fresh-food compartment door 108 is in a closed position (shown in
The first and second endcaps 400, 500 are configured to engage with respective hinges (attached to the cabinet 110) such that the fresh-food compartment door 108 is pivotably secured to the cabinet 110 between its opened and closed positions. More specifically, as will be further discussed below, the first endcap 400 is configured to accept and engage with a hinge 409 (shown in
Now moving on to
As mentioned above, the first and second pockets 404, 406 are recessed from the top wall 402 of the first endcap 400. More specifically, the first and second pockets 404, 406 are formed in (i.e., integral during a single manufacturing process with) the first endcap 400. However, it is contemplated that the first and/or second pockets 404, 406 may be formed separate and distinct from the first endcap 400 and subsequently secured thereto. The first and second pockets 404, 406 are recessed from the top wall 402 such that they each extend away from the top wall 402 (i.e., in a vertically downward direction), and are spatially separated from one another via a boundary 408. The first pocket 404 may be considered a hinge pocket, wherein the first pocket 404 is configured to accept various elements of the hinge 409 (shown in
As further shown in
As depicted, the second wall 414 does not extend completely between the third wall 416 and the fourth wall 418. Rather, the second wall 414 extends from the third wall 416 to an edge 420 such that a gap 422 is disposed between the edge 420 of the third wall 416 and the fourth wall 418. The gap 422 is configured to permit the hinge 409 (shown in
At least one tab 426 (i.e., a protrusion) extends outwards from the peripheral wall and into the first pocket 404. More specifically,
As further show, a locating pin 428 is positioned on the bottom wall 410 and extends vertically outwards therefrom and into the first pocket 404. While
Further, a retention clip 436 is disposed on the bottom wall 410 and extends vertically outwards therefrom and into the first pocket 404. The retention clip 436 is a resilient member wherein a distal end thereof is capable of movement (in short distances). While
A securing member 438 also is disposed on the bottom wall 410 and extends vertically outwards therefrom and into the first pocket 404. The securing member 438 includes an upstanding wall 440 and a fin 442 extending laterally outward from a surface of the upstanding wall 440. Specifically,
Now moving on to
Securing clips 606 extend outwards and away from the top wall 602 in the same general direction that the side wall 604 extends away from the top wall 602. While
As further shown in
Now with reference to
The wireless module 700 functions as a transceiver, capable of both transmitting and receiving information wirelessly through a transmission medium. For example, the wireless module 700 may be configured to transmit/receive information through transmission mediums including, but not limited to, WiFi, Bluetooth, Zigbee, etc. In one example, the wireless module 700 is configured to transmit via one of the IEEE WiFi 802.11 band standards at a frequency of 2.4-2.5 Ghz or 5 Ghz. More specifically, the wireless module 700 shares a communication bus (not shown) with a user interface (not shown) and/or with a main control board (not shown) of the refrigerator 100. That is, the wireless module 700 communicates with an internal communication bus of the refrigerator 100, preferably to a main control board, that sends/receives information to a remote computer server, referred to herein as a cloud server. Of note, the communication between the wireless module 700 and the internal communication bus can be achieved via a wired connection that will run through the door and into the cabinet by the door hinge, or even a wireless connection. An end user may access the cloud server via a mobile application installed on a remote mobile device that is not physically connected to the appliance including, but not limited to, mobile phones, tablets, computers/laptops, smart-devices, etc. In this manner, communication and control capabilities are provided between the end user and the refrigerator 100 from remote locations of the user. For example, the end user may remotely control the temperature of any one of the dedicated compartments (e.g., fresh-food compartment 102, VCZ compartment 104, freezer compartment 106), control ice-making operations of the ice maker 118, and other functions associated with the refrigerator 100. To accomplish the remote control, the user can transmit a command from their mobile device to the cloud server, which in turn will then communicate the command to the appliance. Moreover, the end user may receive notifications from the refrigerator (e.g., conclusion of ice-making operations, expiration of water filter(s), alarms, alerts, etc.). Two-way communication between the appliance and the mobile device can occur in like manners via the intermediary cloud server. Further still, the refrigerator 100 is capable of wirelessly transmitting technical information (e.g., status of refrigerator elements) to improve technical support during servicing/repair. It is contemplated that the wireless module 700 can be configured for direct wireless communication with the mobile device without relying upon the cloud server being an intermediary device.
As the wireless module 700 wirelessly transmits/receives information over a transmission medium (via a communication bus), it is important to position the wireless module 700 at a location in/on the refrigerator 100 that is not overly obstructive in order to ensure proper connectivity and increased range of wireless communication. Further, it is important to place the wireless module 700 at a location where surrounding elements thereof are not made of a material (e.g., metal) that would negatively affect the functionality of the wireless module 700. Additionally, it is beneficial for the wireless module 700 to be outwardly accessible with respect to the refrigerator 100 in order to permit efficient service/replacement thereof.
Reference will now be made to assembly of the fresh-food compartment door 108. Of note, it is to be understood that the below steps are only an example of the assembly process. That is, assembly may be accomplished with additional or fewer steps, and/or in a sequential order that differs from the order described below.
Briefly moving back to
Further, during assembly of the wireless module 700, distal ends of respective retention clips 436 are laterally shifted out of the way to permit the wireless module 700 to be seated on the locating pins 428. This can be accomplished by a user personally moving each of the distal ends of the retention clips 436, or by simply sliding the wireless module 700 into place and thus permitting the peripheral edges of the printed circuit board 702 to displace the distal ends of the retention clips 436 to provide the necessary clearance. After the wireless module 700 is correctly seated on the locating pins 428, the retention clips 436 spring back to their original placement (via an inherent biasing force) such that the distal ends of each retention clip 436 is disposed above the first surface 704 of the printed circuit board 702. Further still, the distal ends of each retention clip 436 may physically contact the first surface 704 of the printed circuit board 702 to ensure proper securement within the first pocket 404 (i.e., the wireless module 700 is secured against vertical movement).
Accordingly, the design of the first endcap 400 permits the wireless module 700 to be installed within the first pocket 404 in a relatively simple and tool-less manner. Additional screws and/or complex securing members are not necessary to ensure proper securement of the wireless module 700 within the first pocket 404, although optionally could be used. Rather, the locating pins 428 are configured and spaced to provide only a single installed orientation of the wireless module 700, and installation can be accomplished by simply dropping the wireless module 700 into seated engagement with the locating pins 428 (e.g., either by manual/user operation, or by automation). Also, the retention clips 436 ensure that the wireless module 700 continuously remains in the installed position. Further, this design provides efficient removal of the wireless module 700 from the first pocket 404 in the event that service work is necessary. That is, the respective distal ends of the retention clips 436 only need to be laterally shifted (i.e., away from the wireless module 700) in order to permit the necessary clearance for removal of the wireless module 700 from the first pocket 404.
Next, with respect to
Thereafter, the cover 600 is installed within the first pocket 404 in a covering manner with respect to the wireless module 700 (as depicted in
As shown in
Thereafter, the remaining parts of the fresh-food compartment door 108 are assembled. For example, with respect to
The above-noted design of the first endcap 400 and the placement of the wireless module 700 therein provides several technical advantages. Initially, as discussed above, the first endcap 400 is manufactured from plastic. Accordingly, the material of the first endcap 400 permits consistent connection between the wireless module 700 and the end user's (remote) mobile device, as opposed to other materials (e.g., metal) known to hinder wireless connectivity. Next, the wireless module 700 is provided within the first endcap 400, which is located adjacent a top-most wall of the cabinet 110. This placement helps to ensure that the wireless module 700 will not be unduly obstructed (from above) when installed at a location selected by the end user. That is, as the fresh-food compartment doors 108 of the refrigerator 100 are often left unobstructed (from above) in order to permit proper pivoting thereof, there is a higher probability of the wireless module 700 not being overly obstructed. Further still, the wireless module 700 is spaced from the bottom wall 410 of the first pocket 404 (via the respective bases 430 of the locating pins 428) and is arranged such that the antenna 708 faces upwards (i.e., a direction opposite to and away from the bottom wall 410 of the first pocket 404), which ensures proper spacing and orientation of the antenna 708 for allowing maximum range connectivity. Also, the cover 600 both conceals and protects the wireless module 700 from accidental damage, while also permitting quick access thereto for servicing. Of note, other electronics can likewise benefit from these advantages provided by the above-described placement/arrangement. For example, temperature and/or humidity sensors (not shown) can be disposed within the first pocket 404 and covered by the cover 600. Again, such placement would both protect the sensor(s) from accidental damage, dust and/or debris, while also providing an easy access point for servicing/repair.
The above-noted advantages are not solely directed to the wireless module 700 being located within the first pocket 404 of the first endcap 400. For example, with respect to
The invention has been described with reference to the example embodiments described above. Modifications and alterations will occur to others upon a reading and understanding of this specification.
