The present subject matter relates generally to refrigerator appliances, and more particularly to autofill water dispensing systems for refrigerator appliances.
Some refrigerator appliances include autofill dispensing systems. Autofill dispensing systems typically include a dispenser housing and a pitcher. When the pitcher is positioned in a designated spot, e.g., within the autofill housing, water is automatically dispensed into the pitcher to a predetermined volume. When chilled water is desired, the pitcher is removed from the refrigerator appliance and the desired amount of liquid is manually dispensed, typically by tilting the pitcher to pour the water from the pitcher. When the pitcher is returned to the dispenser housing, it is automatically refilled to the predetermined volume of water.
In some cases, it may be desirable to dispense chilled water from the pitcher without removing the pitcher from the dispenser housing. For example, a filled pitcher may be too heavy for a user to manipulate safely. In such cases, it may be a benefit to the user to be able to dispense water directly from the pitcher without having to remove, carry, pour, or re-fill the pitcher.
Accordingly, an autofill pitcher system with a dispensing housing that addresses one or more of the challenges noted above would be desirable.
Aspects and advantages of the invention will be set forth in part in the following description, may be apparent from the description, or may be learned through practice of the invention.
In one exemplary aspect, a pitcher for use in an autofill pitcher system within a chamber of a refrigerator appliance is provided. The pitcher defines a height direction, a width direction, and a depth direction. The pitcher comprises a pitcher wall connected to a pitcher bottom defining a pitcher volume, the pitcher wall defining an opening at a top edge of the pitcher, and a spigot defining an axis. The spigot is disposed on the pitcher wall such that the axis is generally parallel to the width direction.
In another example aspect, a refrigerator appliance including an autofill pitcher system and a pitcher is provided. The refrigerator appliance defines a vertical direction, a lateral direction, and a transverse direction and comprises a cabinet having a left side and a right side at least partially defining a fresh food chamber. The refrigerator appliance comprises a door rotatably hinged to an edge of the cabinet at one of the left side and the right side. The door is rotatable between an open position to provide access to the fresh food chamber and a closed position to at least partially seal the fresh food chamber. The autofill pitcher system comprises a pitcher having a pitcher wall connected to a pitcher bottom defining a pitcher volume, the pitcher wall defining an opening at a top edge of the pitcher, and a spigot defining an axis. The autofill pitcher system further comprises a dispenser defining a cavity to receive the pitcher. The spigot is disposed on a portion of the pitcher wall such that the axis is generally parallel to the transverse direction at least when the door is closed.
In yet another example aspect, an autofill pitcher system is disclosed. The autofill pitcher system includes a dispenser defining a cavity to receive a pitcher, the dispenser comprising a fill tube adapted to direct water from a water supply to the pitcher. The pitcher defines a height direction, a width direction, and a depth direction and comprises a pitcher wall connected to a pitcher bottom defining a pitcher volume, the pitcher wall defining an opening at a top edge of the pitcher. The pitcher further comprises a spigot in fluid communication with the pitcher volume, the spigot defining an axis, the spigot disposed on a portion of the pitcher wall such that the axis is generally parallel with the width direction.

Turning to the figures,
Refrigerator appliance 100 includes a housing or cabinet 120 defining a chilled chamber, fresh food chamber 122, and one or more freezer chambers, such as a first freezer chamber 124 and a second freezer chamber 125, which may both be arranged below fresh food chamber 122 along the vertical direction V. As illustrated, fresh food chamber 122 is bounded by vertical walls at the left side 105 and at the right side 106, such walls spaced apart in the lateral direction, a horizontal wall at the top 101 and at the bottom by a lower wall 132. In this configuration, refrigerator appliance 100 may generally be referred to as a bottom mount, or bottom freezer, refrigerator. Cabinet 120 also defines a mechanical compartment (not shown) for receipt of a sealed cooling system (not shown).
Left and right refrigerator doors 126, 128, respectively, are rotatably hinged to an edge of cabinet 120 at left 105 and right 106 sides, respectively, for accessing fresh food chamber 122 (
Left door 126 of refrigerator appliance 100 includes an inner surface 134 and an outer surface 136 (
Doors 126, 128 may include storage bins or shelves 138 movably or fixedly attached to the inner surface 134 of the doors 126, 128. In the embodiment illustrated in
The autofill pitcher system 140 comprises a removable pitcher, pitcher 142, a dispenser 160, and controller 200. The details of exemplary pitcher 142 may best be illustrated with reference to
At a second end of the pitcher, opposite the spout 152, a handle 153 may be disposed or formed on pitcher wall 144 to provide a gripping area to aid in manipulating the pitcher 142. Pitcher 142 may include a tap or spigot 182 (disclosed more fully below) disposed on a portion of the pitcher wall 144 and in selectable fluid communication with volume 148. That is, the spigot 182 may be manually selectable between a position that allows fluid communication or blocks fluid communication with the pitcher volume 148. As illustrated, spigot 182 is beneath the handle 153 and provided to dispense a liquid, typically chilled water, from the pitcher volume 148. In other embodiments, the spigot 182 may be located or disposed on other portions of the pitcher wall 144.
Exemplary pitcher 142 is illustrated as a generally hollow rectangular cuboid for ease of illustration only. Other embodiments may have other shapes, for example a hollow cylinder, and may or may not have features such as a spout or a handle.
An orthogonal coordinate system for the embodiment of water pitcher 142 is defined in
As illustrated in
Lid 154 includes first magnet 172 adjacent to the top wall 158 of lid 154. First magnet 172 may communicate with components of the dispenser 160 to indicate that the pitcher 142 is properly located in the dispenser 160. The lid 154 may also include a pitcher full sensor to communicate to the dispenser 160 that the volume 148 is filled to a predetermined level. In the exemplary embodiment of the
As illustrated at least in
Sensor board 168 is vertically above and adjacent to the lid 154 as shown in
The sensor board 168 includes a first sensor 162 secured to the board to detect the first magnet 172 when the pitcher 142 is properly located in the dispenser 160 to accept a flow of water. The sensor board 168 also includes second sensor 163 positioned such that it is vertically above float body 173 when the pitcher is in the dispenser 160. When the pitcher 142 is in a filled condition as illustrated in

Alternatively, if pitcher 142 was received in dispenser 160 such that depth direction D was generally perpendicular to the inner surface 134 of door 126, it may be preferable to position the spigot on a portion of wall 144 such that axis A is perpendicular to inner surface 134 of door 126. Accordingly, at least when door 126 is in a closed position (
In other embodiments, the dispenser 160 is positioned within the cabinet 120, for example in fresh food chamber 122, to receive pitcher 142 in cavity 161. For accessibility and in order to dispense fluid from pitcher 142 without removing the pitcher form the cabinet, spigot 182 may be positioned on wall 144 such that axis A is generally parallel to the transverse direction T of refrigerator appliance 100.
Spigot 182 may be any type of tap or stopper to manually allow or prevent the flow of liquid from the pitcher volume 148 of pitcher 142.
A plunger 188 may slidingly engage with the body 184 and supported for limited displacement in the H direction. Displacement of plunger 188 in the H direction may be constrained by components of the body 184. Both plunger 188 and the engaging portion of body 184 may have matching tapers to facilitate sealing as illustrated. An upper portion of plunger 188 may be pivotally engaged with lever 190 at pivot 191. Resilient member, spring 192, is contained between lever 190 and plunger 188, biasing the plunger in the downward direction (H direction), sealing the body 184 from pitcher volume 148. A downward force F on lever 190 causes the lever 190 to rotate about fulcrum 194 displacing plunger 188 vertically upward (in the H direction). The vertical displacement moves plunger 188 and body 184 from a sealing engagement and allows contents of the pitcher volume 184 to flow into the body 184 and out through opening 196.
Spigot body 184 may include a projection 198 extending from body 184 vertically below lever 190. Projection 198 may provide a user with a resisting surface when applying downward force F on the lever 190. For example, a user's index finger and thumb may be used to activate the spigot 182. In doing so, the user's index finger may engage the projection 198 and the user's thumb engage the lever 190 to apply force F.
The above description of the spigot 182 is merely illustrative and not limiting. Any other form of spigot or tap may be used, for example a spigot may be rotationally displaced to selectively allow or prevent the flow of liquid from the pitcher 142. As explained herein, aspects of the present subject matter are generally directed to an autofill pitcher of a refrigerator where the autofill pitcher includes a spigot to dispense water. For example, the autofill pitcher includes a water filling/dispensing spout at the top, and the spigot at the bottom to dispense water without removing the pitcher from the refrigerator. This feature provides a cleaner look than the method of dispensing water by removing the pitcher and pouring the contents, and gives alternate options to the customers for getting chilled filtered water.
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 language of the claims.
