The present subject matter relates generally to mechanisms for attaching a dispenser to a refrigerator appliance.
BACKGROUND OF THE INVENTIONRefrigerator appliances generally include a cabinet that defines a chilled chamber for receipt of food items. For example, a cabinet can define a fresh food chamber for receipt of fresh food items and a freezer chamber for receipt of frozen food items. Refrigerator appliances can also include an ice maker for production of ice, e.g., within the freezer chamber.
To access ice produced by the ice maker, an ice dispenser can be provided. The dispenser can be mounted to a door of the appliance, e.g., a freezer or a refrigerator door. The dispenser can include a dispenser recess. To dispense ice, a user can insert a glass or cup into the dispenser recess and actuate a lever within the ice dispenser in order to initiate a flow of ice into the glass or cup.
Various mechanisms can be used to attach the dispenser to the appliance's door. For example, the dispenser can be attached to the appliance's door using fasteners that extend through a front panel of the door into the dispenser. Alternatively, the dispenser can be attached to the front panel of the door using heat staking, ultrasonic welding, or other similar methods. However, such methods for attaching the dispenser can be time consuming to manufacture. For example, an assembly worker may be required to insert and secure each fastener individually or, similarly, heat stake each boss individually. Accordingly, such methods can add to the overall cost of producing the refrigerator appliance. Thus, a refrigerator appliance the does not require fasteners, heat staking, or other similar methods to secure a dispenser to a door of the appliance would be useful.
In addition, trim may be required to cover the fasteners or the boss used to secure the dispenser. Trim can be mounted to the door's front panel to, e.g., cover screw heads or other cosmetically unappealing elements used to secure the dispenser to the door. Such trim can add to the overall cost of producing the refrigerator. In addition, trim can be aesthetically displeasing to certain consumers. Accordingly, a design goal for refrigerator appliances can include providing a trim-less dispenser design.
In trim-less designs, the dispenser can be attached to the refrigerator's door using adhesive tape or glue that does not modify the appearance of the door's front panel and, thus, does not require trim on the front panel. However, applying tape and glue can also be a time consuming and labor intensive process. In addition, tape and/or glue can provide a relatively weak bond or connection between the door and dispenser. Further, tape and glue can provide a poor seal for containing insulating foam during manufacture of the door. For example, insulating foam can be sprayed into the door during assembly. Such foam expands during curing and is preferably contained within the door during assembly to avoid subsequent removal of cured excess foam.
Accordingly, a refrigerator appliance with features for securing a dispenser to a door of the appliance such that trim is not required would be useful. In particular, a refrigerator appliance the does not require glue or tape to secure a dispenser to a door of the appliance would be useful. Further, a refrigerator appliance with features for containing insulating foam within a door of the appliance during assembly would be useful.
BRIEF DESCRIPTION OF THE INVENTIONA refrigerator appliance is provided with features for securing a dispenser to a door of the appliance. The dispenser can include a top wall, a bottom wall and a back wall that define a dispenser recess. An insert includes at least one of the top wall, the bottom wall, and the back wall. The insert is mounted to a back of a front panel of the door. As a result, the dispenser can have a trim-less appearance on the front panel of the door. Aspects and advantages of the invention will be set forth in part in the following description, or may be apparent from the description, or may be learned through practice of the invention.

In the closed position, refrigerator doors 128 extend between a top 101 and a bottom 102 along a vertical direction V and also extend between a first side 105 and a second side 106 along a horizontal direction H. When in a closed position, refrigerator doors 128 further have a thickness between a front 103 and a back 104 (
Dispenser 210 includes a bottom wall 222, a top wall, 224, and a back wall 226. Bottom wall 222 and top wall 224 are spaced apart along the vertical direction V. Back wall 226 extends between bottom wall 222 and top wall 224 along the vertical direction V. A dispenser recess 220 is defined by bottom wall 222, top wall, 224, and back wall 226 of dispenser 210.
Discharging outlet 212 and paddle 214 are an external part of dispenser 210 and are mounted in dispenser recess 220. Discharging outlet 212 is defined adjacent top wall 224 and back wall 226 of dispenser 210. Paddle 214 is mounted adjacent back wall 226. Dispenser 210 is positioned at a predetermined elevation convenient for a user to access ice or water enabling the user to access ice without the need to bend-over, and without the need to access freezer compartment 124. In the exemplary embodiment, dispenser 210 is positioned at a level that approximates the chest level of a user.

Tabs 320 are mounted to first exemplary insert 300. Tabs 320 are configured for securing first exemplary insert 300 to door 128 as discussed in greater detail below. Tabs 320 extend between a first end 321 and a second end 322. First end 321 of tabs 320 are fixed to first exemplary insert 320. Second end 322 of tabs 320 are spaced apart from first end 321 of tabs 320 such that tabs 320 extends away from first exemplary insert 300, e.g., along the transverse direction T.

Wedge 520 is mounted in slot 510 such the wedge 520 extends through back wall 226 along transverse direction T. Thus, chock 522 is disposed within slot 510, and lip 524 is disposed adjacent back wall 226. As discussed above, fasteners 530 couple wedge 520 and third exemplary insert 500 such that third exemplary insert 500 is secured to door 128. For example, wedge 520 impacts bottom of slot 510 when third exemplary inset 500 is urged downwardly along vertical direction V. Similarly, wedge 520 impacts back wall 226 adjacent slot 510 if third exemplary inset 500 is urged along transverse direction T. For example, lip 524 of wedge 520 impacts back wall 226 adjacent slot 510 if third exemplary inset 500 is urged along transverse direction T.

In addition, as may be seen in
As discussed above,
The various attachment mechanisms illustrated in the first exemplary insert 200, second exemplary insert 300, third exemplary insert 400, and fourth exemplary insert 500, provide reliable and robust mechanisms for securing the inserts 200, 300, 400, and 500 to the door 120. Also, the various attachment mechanisms provide a seal that can prevent insulating foam from leaking out of door 120. For example, during manufacture of door 120, door 120 is filled with insulating foam. As will be understood by those skilled in the art, without the robust seal provided by the attachment mechanisms such foam could leak out between the dispenser 210 and the door 120 during assembly.
In addition, a gasket (not shown) may be disposed between dispenser 210 and any of the inserts (first exemplary insert 200, second exemplary insert 300, third exemplary insert 400, or fourth exemplary insert 500). As an example, the gasket can be disposed on interior surface 236 and extend between interior surface 236 of door 120 and the insert. The gasket can provide improved sealing and/or prevent foam insulation from leaking out between the dispenser 210 and the door 120 during assembly. Thus, the gasket can have a shape that corresponds to the shape of the interface between the inserts and the door 120 as will be understood by those skilled in the art.
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.
