Converging section 272 of Venturi pump 270 is disposed upstream of diverging section 274 of Venturi pump 270 relative to the flow of water F through Venturi pump 270 . As the flow of water F enters converging section 272 of Venturi pump 270 , the flow of water F may increase in velocity and decrease in pressure. Conversely, as the flow of water passes from converging section 272 of Venturi pump 270 into diverging section 274 of Venturi pump 270 , the flow of water F may increase in pressure and decrease in velocity.
- Supply conduit 280 extends between an inlet 282 and an outlet 284 , e.g., along the lateral direction L.
- Inlet 282 of supply conduit 280 is disposed within reservoir 260 , e.g., at or adjacent bottom wall 268 of reservoir 260 .

- the change in pressure for the flow of water F through Venturi pump 270 may assist with drawing detergent from reservoir 260 .
- internal volume 161 of reservoir 260 may be exposed to or contiguous with ambient air about washing machine appliance 100 (e.g., via inlet 267 of reservoir 260 ), and outlet 284 of supply conduit 280 may be positioned on Venturi pump 270 (e.g., converging section 272 of Venturi pump 270 or diverging section 274 of Venturi pump 270 ) such that a pressure of fluid at outlet 284 of supply conduit 280 is less than the pressure of detergent within reservoir 260 at inlet 282 of supply conduit 280 .
- Venturi pump 270 may pump the flow of detergent D from reservoir 260 to Venturi pump 270 via supply conduit 280 when the flow of water F passes through Venturi pump 270 .
- the flow of water F and the flow of detergent D mix and a mixture of water and detergent M exits Venturi pump 270 and flows into tub 118 .
- detergent from reservoir 260 may be dispensed in to tub 118 .
- the shape, construction and location of reservoir 260 can assist with providing a very cost-effective bulk dispense system that delivers accurate fluid additive dosing, e.g., without the use of a costly pressure sensor.
- Venturi pump 270 When Venturi pump 270 is actuated for a predetermined amount of time, the amount of fluid additive dispensed from reservoir 260 to Venturi pump 270 is essentially constant, e.g., because the priming time of Venturi pump 270 is also essentially constant, within a small but acceptable error, whatever the fill level of fluid additive within reservoir 260 .
- the priming time of Venturi pump 270 when reservoir 260 is full will be about equal to the priming time of Venturi pump 270 when reservoir 260 is almost empty due to the low vertical profile of reservoir 260 .
- the level of fluid additive within reservoir 260 can vary by less than six inches between full and empty such that the priming time of Venturi pump 270 is similar in both circumstances.
- a middle portion 286 of supply conduit 280 between inlet and outlet 282 , 284 of supply conduit 280 may be positioned above inlet and outlet 282 , 284 of supply conduit 280 along the vertical direction V.

Description
- The present subject matter relates generally to washing machine appliances, such as vertical axis washing machine appliances.
- Washing machine appliances generally include a tub for containing water or wash liquid, e.g., water and detergent, bleach, and/or other wash additives. A basket is rotatably mounted within the tub and defines a wash chamber for receipt of articles for washing. During normal operation of such washing machine appliances, the wash liquid is directed into the tub and onto articles within the wash chamber of the basket. The basket or an agitation element can rotate at various speeds to agitate articles within the wash chamber, to wring wash fluid from articles within the wash chamber, etc.
- During operation of certain washing machine appliances, a volume of wash liquid is directed into the tub in order to wash and/or rinse articles within the wash chamber. One or more fluid additives may be added to the wash liquid to enhance the cleaning or other properties of the wash liquid. The fluid additives may be in powder or concentrated liquid form, and are generally added to a dispenser box of the washing machine appliance by, e.g., a user of the washing machine appliance. The dispenser box may contain various chambers for containing different additives, e.g., wash detergent and softener. Water may be directed into the chambers of the dispenser box through a plurality of water inlet valves to mix with the additives and the resulting wash liquid is then dispensed into the wash chamber.
- The volume of water or wash liquid needed may vary depending upon a variety of factors. For example, large loads can require a large volume of water relative to small loads that can require a small volume of water. A user may wish to have additional wash liquid dispensed in order to perform a specific task, e.g., prewash an article of clothing or add additional liquid to accommodate an extra-large load. The ability to adjust the amount of water or wash liquid dispensed is a generally commercially desirable feature and increases the user's positive perception of the wash process generally. However, conventional washing machine appliances typically do not have water-on-demand features, and those that do require additional nozzles, hoses, clamps, and other hardware to perform such a function.
- Accordingly, a washing machine appliance that provides a user with more control over the water or wash liquid fill amount is desirable. In particular, a dispenser box having a simple, convenient, integrated system for dispensing an additional predetermined amount of wash liquid would be particularly beneficial.
- The present subject matter provides a washing machine appliance with a supply conduit having an exit positioned for directing water into a basket. A door is positioned over the basket in a closed position. A water valve is coupled to the supply conduit. A controller opens the water valve in response to actuation of a water supply input and a signal from a sensor that the door is in the open position. Additional 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 a first exemplary embodiment, a washing machine appliance is provided. The washing machine appliance includes a tub. A basket is disposed within the tub so that the basket is rotatable within the tub. A door is adjustable between an open position and a closed position. The door is positioned over the basket in the closed position. A supply conduit has an exit positioned for directing water into the basket. A water valve is coupled to the supply conduit. The water valve is actuatable to regulate a flow of water through the supply line into the basket. A control panel is positioned above the tub. The control panel includes a plurality of user inputs including a water supply input. A controller is in operative communication with the water valve and the plurality of user inputs. The controller opens the water valve in response to actuation of the water supply input and a signal from a sensor that the door is in the open position.
- In a second exemplary embodiment, a vertical axis washing machine appliance includes a cabinet having a top panel. A tub is disposed within the cabinet below the top panel. A basket is rotatable about a substantially vertical axis within the tub. A door is mounted to the cabinet at the top panel such that the door is adjustable between an open position and a closed position. The door is positioned over the basket in the closed position. A supply conduit has an exit positioned over the basket. A water valve is coupled to the supply conduit. The water valve is actuatable to regulate a flow of water through the supply line into the basket. A control panel is mounted to the top panel of the cabinet. The control panel includes a plurality of user inputs including a water supply input. A controller is in operative communication with the water valve and the plurality of user inputs. The controller opens the water valve in response to actuation of the water supply input and a signal from a sensor that the door is in the open position. The controller closes the water valve in response to a signal from the sensor that the door is in the closed position or after a predetermined amount of time.
- These and other features, aspects and advantages of the present invention will become better understood with reference to the following description and appended claims. The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIGS. 1 and 2 illustrate an exemplary embodiment of a vertical axiswashing machine appliance 100. InFIG. 1 , a lid ordoor 130 is shown in a closed position. InFIG. 2 ,door 130 is shown in an open position.Washing machine appliance 100 generally defines a vertical direction V, a lateral direction L, and a transverse direction T, which are mutually perpendicular with one another, such that an orthogonal coordinate system is generally defined. - While described in the context of a specific embodiment of vertical axis
washing machine appliance 100, using the teachings disclosed herein it will be understood that vertical axiswashing machine appliance 100 is provided by way of example only. Other washing machine appliances having different configurations, different appearances, and/or different features may also be utilized with the present subject matter as well, e.g., horizontal axis washing machines. -
Washing machine appliance 100 has acabinet 102 that extends between atop portion 103 and abottom portion 104 along the vertical direction V. A wash tub 118 (FIG. 6 ) is disposed withincabinet 102, and awash basket 120 is rotatably mounted withintub 118. A motor (not shown) is in mechanical communication withwash basket 120 to selectively rotate wash basket 120 (e.g., during an agitation or a rinse cycle of washing machine appliance 100). Washbasket 120 defines awash chamber 121 that is configured for receipt of articles for washing.Tub 118 holds wash and rinse fluids for agitation inwash basket 120 withintub 118. An agitator or impeller (not shown) extends intowash basket 120 and is also in mechanical communication with the motor. The impeller assists agitation of articles disposed withinwash basket 120 during operation ofwashing machine appliance 100. -
Cabinet 102 ofwashing machine appliance 100 has atop panel 140, e.g., attop portion 103 ofcabinet 102.Top panel 140 defines anaperture 105 that permits user access to washbasket 120 oftub 118.Door 130, rotatably mounted totop panel 140, permits selective access toaperture 105; in particular,door 130 selectively rotates between the closed position shown inFIG. 1 and the open position shown inFIG. 2 . In the closed position,door 130 inhibits access to washbasket 120. Conversely, in the open position, a user can access washbasket 120. Awindow 136 indoor 130 permits viewing ofwash basket 120 whendoor 130 is in the closed position, e.g., during operation ofwashing machine appliance 100.Door 130 also includes ahandle 132 that, e.g., a user may pull and/or lift when opening and closingdoor 130. Further, althoughdoor 130 is illustrated as mounted totop panel 140, alternatively,door 130 may be mounted tocabinet 102 or any other suitable support. -
Top panel 140 also defines a hole or opening 142, e.g., at a corner oftop panel 140 at or adjacent afront portion 122 oftop panel 140 as shown inFIG. 2 . Opening 142 is configured for receipt of one of a plurality of fluid additives, e.g., detergent, fabric softener, and/or bleach. Opening 142 permits the fluid additive to pass throughtop panel 140 to a reservoir 260 (FIG. 6 ) disposed belowtop panel 140 along the vertical direction V. Thus, a user may pour the fluid additive intoreservoir 260 through opening 142 intop panel 140.Reservoir 260 is described in greater detail below. - A
control panel 110 with at least oneinput selector 112 extends fromtop panel 140, e.g., at arear portion 124 ofcabinet 102 opposite opening 142 aboutaperture 105 along the transverse directionT. Control panel 110 andinput selector 112 collectively form a user interface input for operator selection of machine cycles and features. Adisplay 114 ofcontrol panel 110 indicates selected features, operation mode, a countdown timer, and/or other items of interest to appliance users regarding operation. - Operation of
washing machine appliance 100 is controlled by a controller orprocessing device 108 that is operatively coupled to controlpanel 110 for user manipulation to select washing machine cycles and features. In response to user manipulation ofcontrol panel 110,controller 108 operates the various components ofwashing machine appliance 100 to execute selected machine cycles and features. -
Controller 108 may include a memory and microprocessor, such as a general or special purpose microprocessor operable to execute programming instructions or micro-control code associated with a cleaning cycle. The memory may represent random access memory such as DRAM, or read only memory such as ROM or FLASH. In one embodiment, the processor executes programming instructions stored in memory. The memory may be a separate component from the processor or may be included onboard within the processor. Alternatively,controller 100 may be constructed without using a microprocessor, e.g., using a combination of discrete analog and/or digital logic circuitry (such as switches, amplifiers, integrators, comparators, flip-flops, AND gates, and the like) to perform control functionality instead of relying upon software.Control panel 110 and other components ofwashing machine appliance 100 may be in communication withcontroller 108 via one or more signal lines or shared communication busses. - During operation of
washing machine appliance 100, laundry items are loaded intowash basket 120 throughaperture 105, and washing operation is initiated through operator manipulation ofinput selectors 112.Tub 118 is filled with water and detergent and/or other fluid additives viadispenser box assembly 200, which will be described in detail below. One or more valves can be controlled bywashing machine appliance 100 to provide for fillingwash basket 120 to the appropriate level for the amount of articles being washed and/or rinsed. By way of example for a wash mode, once washbasket 120 is properly filled with fluid, the contents ofwash basket 120 can be agitated (e.g., with an impeller as discussed previously) for washing of laundry items inwash basket 120. - After the agitation phase of the wash cycle is completed, wash
basket 120 can be drained. Laundry articles can then be rinsed by again adding fluid to washbasket 120 depending on the specifics of the cleaning cycle selected by a user. The impeller may again provide agitation withinwash basket 120. One or more spin cycles also may be used. In particular, a spin cycle may be applied after the wash cycle and/or after the rinse cycle to wring wash fluid from the articles being washed. During a spin cycle, washbasket 120 is rotated at relatively high speeds. After articles disposed inwash basket 120 are cleaned and/or washed, the user can remove the articles fromwash basket 120, e.g., by reaching intowash basket 120 throughaperture 105. - Referring now generally to
FIGS. 2 through 5 ,dispenser box assembly 200 will be described in more detail. Although described in greater detail below in the context ofwashing machine appliance 100, it will be understood thatdispenser box assembly 200 may be used in or with any other suitable washing machine appliance, in alternative exemplary embodiments. In addition, other configurations ofdispenser box assembly 200 may be provided as well. For example,dispenser box assembly 200 may be positioned on a front ofcabinet 102, may have a different shape or chamber configuration, and may dispense water, detergent, or other additives. Other variations and modifications of the exemplary embodiment described below are possible, and such variations are contemplated as within the scope of the present subject matter. -
Dispenser box assembly 200 is a box having a substantially rectangular cross-section that defines a top 202 and a bottom 204, e.g., spaced apart along the vertical direction V.Dispenser box assembly 200 also defines afront side 206 and aback side 208, e.g., spaced apart along the transverse direction T. As best shown inFIGS. 2 and 3 ,dispenser box assembly 200 may be mounted underneathtop panel 140 ofcabinet 102, e.g., atrear portion 124 ofcabinet 102, such thatfront side 206 is visible insideaperture 105. More specifically,dispenser box assembly 200 may be mounted totop panel 140 using a plurality of mountingfeatures 210, which may, for example, be configured to receive mechanical fasteners. One skilled in the art will appreciate thatdispenser box assembly 200 may be mounted in other locations and use other mounting mechanisms in alternative exemplary embodiments. -
Dispenser box assembly 200 may define amixing chamber 220 configured to receive one or more additive compartments. For example, according to the illustrated embodiment, mixingchamber 220 may be configured to slidably receive adetergent compartment 222 and asoftener compartment 224. Detergent andsoftener compartments chamber 220 usingslides 226 and are connected to afront panel 228 of dispenser box assembly. In this manner, a user may pull onfront panel 228 to slide detergent andsoftener compartments detergent compartment 222 andsoftener compartment 224 may be conveniently filled with detergent and softener, respectively.Front panel 228 may be then be pushed back into mixingchamber 220, e.g., before a wash cycle begins. - Although the illustrated embodiment shows
detergent compartment 222 andsoftener compartment 224 slidably received in mixingchamber 220 for receiving wash additives, one skilled in the art will appreciate that different configurations are possible in alternative exemplary embodiments. For example, more compartments may be used and the compartments may be accessed by a lid instead of sliding out of mixingchamber 220. In addition, as discussed in greater detail below, mixingchamber 220 may draw wash additives from a separate storage container such that slidingcompartments chamber 220. -
Dispenser box assembly 200 may further include a plurality of valves configured to supply hot and cold water to mixingchamber 220 or directly totub 118. For example, according to the illustrated embodiment, a plurality of apertures may be defined ontop 202 of mixingchamber 220 for receiving water. Each aperture (not shown) may be in fluid communication with a different portion of the mixing chamber. A plurality of valve seats may be positioned over top of each of those apertures to receive a valve that controls the flow of water through each aperture. - For example, a
first valve seat 234 may be in fluid communication with a first aperture for providing hot water intodetergent compartment 222. Asecond valve seat 236 may be in fluid communication with a second aperture for providing cold water intodetergent compartment 222. Athird valve seat 238 may be in fluid communication with a third aperture for providing cold water intosoftener compartment 224. Afourth valve seat 240 may be in fluid communication with a fourth aperture for providing cold water into mixingchamber 220 or directly intotub 118. - Water inlets may be placed in fluid communication with each of
valve seats hot water inlet 244 may be connected to a hot water supply line (not shown) and acold water inlet 246 may be connected to a cold water supply line (not shown). According to the illustrated embodiment, eachwater inlet water inlets water inlets - Notably,
hot water inlet 244 is in direct fluid communication withfirst valve seat 234. However, becausewashing machine appliance 100 uses cold water for multiple purposes,cold water inlet 246 is in fluid communication with acold water manifold 248. As best shown inFIG. 5 ,cold water manifold 248 is a cylindrical pipe that extends along the lateral direction fromsecond valve seat 236 tofourth valve seat 240. In this manner,cold water manifold 248places valve seats cold water inlet 246. - Each of
valve seats water valve 252 for controlling the flow of water through a corresponding aperture into mixingchamber 220.Water valve 252 may be, for example, a solenoid valve that is electrically connected tocontroller 108. However, any other suitable water valve may be used to control the flow of water.Controller 108 may selectively open andclose water valves 252 to allow water to flow fromhot water inlet 244 throughfirst valve seat 234 and fromcold water manifold 248 through one or more ofsecond valve seat 236,third valve seat 238, andfourth valve seat 240. -
Dispenser box assembly 200 may also include one or more outlets (not shown) for directing wash fluid, such as water and/or a mixture of water and at least one fluid additive, e.g., detergent, fabric softener, and/or bleach intotub 118 fromdispenser box assembly 200. For example, whensecond valve seat 236 is open, water may flow fromcold water inlet 246 throughcold water manifold 248 andsecond valve seat 236 intodetergent compartment 222. Water may mix with detergent placed indetergent compartment 222 to create wash liquid to be dispensed intotub 118. - An outlet (not shown) may be positioned on the bottom of
detergent compartment 222 or on the bottom of mixingchamber 220 to dispense the wash fluid intotub 118. According to the illustrated embodiment,dispenser box assembly 200 may include four outlets; each associated with a respective one ofvalves seats chamber 220 neartub 118 or directly ontub 118, but could be positioned in other locations as well. -
FIG. 6 provides a schematic view of certain components ofwashing machine appliance 100.FIG. 7 provides a perspective view of areservoir 260 ofwashing machine appliance 100 fluidly coupled todispenser box assembly 200. Although described in greater detail below in the context ofwashing machine appliance 100 anddispenser box assembly 200, it will be understood thatreservoir 260 may be used in or with any other suitable washing machine appliance and/or withoutdispenser box assembly 200, in alternative exemplary embodiments. In addition, other configurations ofreservoir 260 may be provided as well. For example,reservoir 260 may be positioned on a front ofcabinet 102, may have a different shape or chamber configuration. Other variations and modifications of the exemplary embodiment described below are possible, and such variations are contemplated as within the scope of the present subject matter. -
Reservoir 260 may be filled with detergent, andwashing machine appliance 100 includes features for drawing detergent withinreservoir 260 todispenser box assembly 200. Withindispenser box assembly 200, the detergent fromreservoir 260 is mixed with water and directed intotub 118 ofwashing machine appliance 100. Thus,reservoir 260 may contain a bulk volume of detergent (e.g., or other suitable fluid additive) such thatreservoir 260 is sized for holding a volume of detergent sufficient for a plurality of wash cycles ofwashing machine appliance 100, such as no less than twenty wash cycles, no less than fifty wash cycles, etc. As a particular example, aninternal volume 261 ofreservoir 260 is configured for containing detergent therein, and theinternal volume 261 ofreservoir 260 may be no less than twenty fluid ounces, no less than three-quarters of a gallon or about one gallon. As used herein the term “about” means within half a gallon of the stated volume when used in the context of volumes. Thus, a user can avoid fillingdispenser box assembly 200 with detergent before each operation of washing machine appliance by fillingreservoir 260 with detergent. - As discussed above,
reservoir 260 is positioned below top panel 140 (FIG. 2 ). In particular, aninlet 267 ofreservoir 260 may be positioned at (e.g., directly below) opening 142 oftop panel 140. Thus, a user may pour detergent intoreservoir 260 via opening 142 oftop panel 140 in order to load or fillreservoir 260 with detergent. -
Reservoir 260 includes aplanar sidewall 262, anarcuate sidewall 264, atop wall 266 and abottom wall 268.Planar sidewall 262 andarcuate sidewall 264 orreservoir 260 are spaced apart from each other, e.g., along the lateral directionL. Top wall 266 and abottom wall 268 ofreservoir 260 are also spaced apart from each other, e.g., along the vertical directionV. Planar sidewall 262 andarcuate sidewall 264 ofreservoir 260 may extend along the vertical direction V betweentop wall 266 and abottom wall 268 ofreservoir 260 in order to connecttop wall 266 ofreservoir 260 tobottom wall 268 ofreservoir 260.Reservoir 260 may also include end walls (not labeled) that are spaced apart from each other, e.g., along the transverse direction T, and that extend along the vertical direction V betweentop wall 266 andbottom wall 268 ofreservoir 260 in order to connecttop wall 266 ofreservoir 260 tobottom wall 268 ofreservoir 260.Reservoir 260 may be formed from any suitable material, such as molded plastic. -
Reservoir 260 has a height H along the vertical direction V. The height H ofreservoir 260 may be defined betweentop wall 266 andbottom wall 268 ofreservoir 260.Reservoir 260 also has a width W along the lateral direction L. The width W ofreservoir 260 may be defined betweenplanar sidewall 262 andarcuate sidewall 264 of reservoir 260 (e.g., at the portion ofreservoir 260 whereplanar sidewall 262 andarcuate sidewall 264 ofreservoir 260 are most spaced apart from each other along the lateral direction L).Reservoir 260 further has a breadth B along the transverse direction T. The breadth B ofreservoir 260 may be defined between the opposing end walls ofreservoir 260. -
Reservoir 260 may be sized such thatreservoir 260 is shorter along the vertical direction V than along the transverse direction T and/or the lateral direction L. For example, the height H ofreservoir 260 may be no greater than six inches or no greater than four inches. As another example, the height H ofreservoir 260 may be about four inches. As used herein, the term “about” means within half an inch of the stated height when used in the context of heights. Thus,reservoir 260 may have a small profile along the vertical direction V undertop panel 140. - In contrast to the low vertical profile of
reservoir 260, the width W and/or breadth B ofreservoir 260 may be larger than the height H ofreservoir 260. For example, the width W ofreservoir 260 may be less than twelve inches and greater than six inches or less than ten inches and greater than seven inches. As another example, the width W ofreservoir 260 may be about eight inches. As used herein, the term “about” means within an inch of the stated width when used in the context of widths. With respect to the breadth B ofreservoir 260, as an example, the breadth B ofreservoir 260 may be less than twenty-eight inches and greater than sixteen inches or less than twenty-four inches and greater than eighteen inches. As another example, the breadth B ofreservoir 260 may be about twenty-four inches. As used herein, the term “about” means within three inches of the stated breadth when used in the context of breadths. Thus,reservoir 260 may have a small profile along the vertical direction V undertop panel 140 while still being sized to contain a significant volume of detergent, e.g., no less than three-quarters of a gallon of detergent. -
Washing machine appliance 100 includes various features for drawing detergent fromreservoir 260 and directing the detergent intotub 118. For example,washing machine appliance 100 includes aVenturi pump 270 and asupply conduit 280.Supply conduit 280 extends betweenreservoir 260 and Venturi pump 270, and Venturi pump 270 draws detergent fromreservoir 260 when a valve associated with Venturi pump 270 is open and water flows throughVenturi pump 270. As an example, Venturi pump 270 may be configured to receive a flow of water F when one valve seat position ofwater valve 252 is opened (e.g., thewater valve 252 on second valve seat 236). Thus, when one valve seat position ofwater valve 252 is open, the flow of water F may pass throughVenturi pump 270. - As may be seen in
FIG. 6 , Venturi pump 270 may be disposed on or formed withdispenser box assembly 200. In alternative exemplary embodiments, Venturi pump 270 may be disposed on or formed with any other suitable component ofwashing machine appliance 100. Venturi pump 270 includes a convergingsection 272 and a diverging section 274. Convergingsection 272 of Venturi pump 270 is disposed upstream of diverging section 274 of Venturi pump 270 relative to the flow of water F throughVenturi pump 270. As the flow of water F enters convergingsection 272 ofVenturi pump 270, the flow of water F may increase in velocity and decrease in pressure. Conversely, as the flow of water passes from convergingsection 272 of Venturi pump 270 into diverging section 274 ofVenturi pump 270, the flow of water F may increase in pressure and decrease in velocity. -
Supply conduit 280 extends between aninlet 282 and anoutlet 284, e.g., along the lateraldirection L. Inlet 282 ofsupply conduit 280 is disposed withinreservoir 260, e.g., at or adjacentbottom wall 268 ofreservoir 260.Outlet 284 ofsupply conduit 280 is disposed atVenturi pump 270. A flow of detergent D may entersupply conduit 280 atinlet 282 ofsupply conduit 280, flow throughsupply conduit 280 to Venturi pump 270 and enter Venturi pump 270 viaoutlet 284 ofsupply conduit 280. - The change in pressure for the flow of water F through Venturi pump 270 may assist with drawing detergent from
reservoir 260. For example, internal volume 161 ofreservoir 260 may be exposed to or contiguous with ambient air about washing machine appliance 100 (e.g., viainlet 267 of reservoir 260), andoutlet 284 ofsupply conduit 280 may be positioned on Venturi pump 270 (e.g., convergingsection 272 of Venturi pump 270 or diverging section 274 of Venturi pump 270) such that a pressure of fluid atoutlet 284 ofsupply conduit 280 is less than the pressure of detergent withinreservoir 260 atinlet 282 ofsupply conduit 280. Thus, Venturi pump 270 may pump the flow of detergent D fromreservoir 260 to Venturi pump 270 viasupply conduit 280 when the flow of water F passes throughVenturi pump 270. Within Venturi pump 270, the flow of water F and the flow of detergent D mix and a mixture of water and detergent M exits Venturi pump 270 and flows intotub 118. In such a manner, detergent fromreservoir 260 may be dispensed in totub 118. - The shape, construction and location of
reservoir 260 can assist with providing a very cost-effective bulk dispense system that delivers accurate fluid additive dosing, e.g., without the use of a costly pressure sensor. When Venturi pump 270 is actuated for a predetermined amount of time, the amount of fluid additive dispensed fromreservoir 260 to Venturi pump 270 is essentially constant, e.g., because the priming time of Venturi pump 270 is also essentially constant, within a small but acceptable error, whatever the fill level of fluid additive withinreservoir 260. For example, the priming time of Venturi pump 270 whenreservoir 260 is full will be about equal to the priming time of Venturi pump 270 whenreservoir 260 is almost empty due to the low vertical profile ofreservoir 260. In particular, the level of fluid additive withinreservoir 260 can vary by less than six inches between full and empty such that the priming time of Venturi pump 270 is similar in both circumstances. - As may be seen in
FIG. 7 , amiddle portion 286 ofsupply conduit 280 between inlet andoutlet supply conduit 280 may be positioned above inlet andoutlet supply conduit 280 along the vertical direction V. In addition,top wall 266 ofreservoir 260 may face and be positioned attop panel 140. Thus,supply conduit 280 may extend throughtop panel 140 such thatmiddle portion 286 ofsupply conduit 280 betweenreservoir 260 and Venturi pump 270 is positioned abovetop panel 140 along the vertical direction V. In particular,middle portion 286 ofsupply conduit 280 may be positioned abovetop panel 140 along the vertical direction V and be disposed withincontrol panel 110. In such a manner,supply conduit 280 may extend betweenreservoir 260 and Venturi pump 270. - In some situations, a user may wish to add additional water to wash
tub 121. For example, a user may wish to prewash one or more articles of clothing or may perceive that more water is needed to effectively wash a load. Accordingly,dispenser box assembly 200 may include a system for allowing a user to add water to washtub 121 on demand, i.e., a water-on-demand feature. Such features are discussed in greater detail below in the context ofFIGS. 8 and 9 . -
FIG. 8 provides a schematic view of certain components ofwashing machine appliance 100. As may be seen inFIGS. 2 and 8 ,washing machine appliance 100 includes asensor 250 that is positionedproximate door 130.Sensor 250 is configured for detecting whendoor 130 is in the open position and is in communication withcontroller 108. Thus,sensor 250 may signalcontroller 108 whendoor 130 is in the open position.Sensor 250 may be any suitable type of sensor for detecting whendoor 130 is in the open position. As an example,sensor 250 may be a plunger switch that is actuated whendoor 130 shifts from the closed position to the open position. As another example,sensor 250 may be a reed switch or Hall Effect sensor that is actuated, e.g., by a magnet ondoor 130, whendoor 130 shifts from the closed position to the open position. As an additional example,sensor 250 may be a pressure sensor or an optical sensor that is actuated whendoor 130 shifts from the closed position to the open position. One of ordinary skill in the art will recognize that other types of sensors may be used assensor 250 to detect whendoor 130 is in the open position. -
FIG. 9 provides a front view of arotatable knob 113 of washing machine appliance ofFIG. 1 .Knob 113 is part ofinput selectors 112 oncontrol panel 110. A user may rotate knob to any of the lines illustrated inFIG. 9 to input a control command associated with each line tocontroller 108. As an example, the user may initiate a normal wash cycle by rotatingknob 113 to the top line labeled “normal” inFIG. 9 .Knob 113 may be rotated to any of the other lines to initiate the cycle labeled with each line, as will be understood by those skilled in the art. It should be understood thatknob 113 may include alternative inputs (e.g., positions), more inputs or less inputs in alternative exemplary embodiments. Thus,knob 113 is provided by way of example only and is not intended to limit the present subject matter to any particular number or type of inputs. - As may be seen in
FIGS. 8 and 9 ,washing machine appliance 100 includes one or more user inputs that are configured to control one or more ofvalves 252. According to the exemplary embodiment illustrated inFIG. 9 ,knob 113 includes acold water input 254, ahot water input 256 and a water-detergent mixture input (or fluid additive-water mixture input) 258 for controllingvalves 252 onfirst valve seat 234,fourth valve seat 240 andsecond valve seat 236, respectively. However, one skilled in the art will appreciate that additional inputs may be included and the inputs may controldifferent valves 252 or any combination ofvalves 252. In addition, one skilled in the art will appreciate that any of these inputs can be turned on/off independently or together in any combination. - In alternative exemplary embodiments,
cold water input 254,hot water input 256 and water-detergent mixture input 258 (hereinafter also referred to as “inputs controller 108 that a particular action should be initiated. For example,inputs -
Cold water input 254,hot water input 256 and water-detergent mixture input 258 are located oncontrol panel 110. As shown inFIGS. 1 and 2 ,door 130 is disposed overcontrol panel 110 in the open position. Thus, whendoor 130 is in the open position, user access tocontrol panel 110 fromfront portion 122 oftop panel 140 may be blocked bydoor 130 due todoor 130 being positioned between the user andcontrol panel 110, e.g., along the transverse direction T.Washing machine appliance 100 includes water-on-demand features that allow dispensing of water to washtub 121 despitedoor 130 blockingcontrol panel 110 andinput selectors 112 thereon in the open position. -
Inputs tub 121 on demand, e.g., during or prior to any cycle, whensensor 250 detects thatdoor 130 is in the open position. The additional amount of water may be a specific volume of water orvalves 252 may simply be opened for a specific amount of time. For example, according to an exemplary embodiment, in response to auser rotating knob 113 tohot water input 256 and then openingdoor 130,controller 108 opensvalve 252 seated onfirst valve seat 234 and delivers hot water todetergent compartment 222 or mixingchamber 220 for twenty seconds. However, one skilled in the art will appreciate that water may be delivered for other time durations as controlled by the user, e.g., via settings oncontroller 108, or as set by the manufacturer. Indeed, these values may be set by the manufacturer, determined bycontroller 108 based on the operating parameters selected, selected by the consumer, or set in any other suitable manner. - One skilled in the art will appreciate that the amount of water added to wash
tub 121 uponrotating knob 113 to one ofinputs door 130 may vary depending on the application or wash cycle. Similarly, the amount of water delivered may be preset (as described above) such thatrotating knob 113 to one ofinputs door 130 delivers the predetermined amount of water. Alternatively,valves 252 may be configured to remain open at all times whenknob 113 is rotated to one ofinputs door 130 is open. In this manner, a user may precisely control the amount of water added to washtub 121. In order to ensure thatwash tub 121 is never overfilled, a maximum water level sensor may be included in thewash tub 121. When water reaches the maximum level,controller 108 may automatically close allvalves 252 or perform a drain cycle to prevent water from spilling out ofwash tub 121. - To operate Venturi pump 270 and dispense the mixture of water and detergent M, a user may rotate
knob 113 to water-detergent mixture input 258. In response to rotation ofknob 113 to water-detergent mixture input 258 and openingdoor 130,controller 108 opens one ofvalves 252, e.g.,valve 252 onsecond valve seat 236, such that the flow of water F enters Venturi pump 270 and draws the flow of detergent D fromreservoir 260. Thus, to selectively dispense the mixture of water and detergent M, a user may rotateknob 113 to water-detergent mixture input 258 and thenopen door 130. In such a manner, the user may dispense the mixture of water and detergent M on demand. - As discussed above,
controller 108 receives a signal fromsensor 250 whendoor 130 is in the open position and then opens one ofvalves 252 to dispense wash fluid. By requiring thatdoor 130 be in the open position before dispensing wash fluid, the user may easily accessknob 113 to select one ofinputs door 130 blocking access tocontrol panel 110. After selecting one ofinputs control panel 110, the user opensdoor 130, andsensor 250 is triggered andsignals controller 108 thatdoor 130 is open.Controller 130 the opens the respective one ofvalves 252 associated with the selected one ofinputs door 130 to be open prior to openingvalve 252, the user may easily utilize or view the steam offluid entering basket 120, e.g., without having to race toopen door 130. - Notably,
inputs valves 252 that are already included onwashing machine appliance 100. This obviates the need for additional hardware required for an independent water delivery system, e.g., nozzles, high voltage circuits, mounting hardware, etc. As a result, the water-on-demand feature provides an inexpensive, reliable, simple, and intuitive system to deliver additional water to washtub 121 when the user desires. Similarly, becausevalves 252 and water delivery system may be integrated into an existingcontrol panel 110,washing machine appliance 100 may have a more aesthetically pleasing appearance. In addition, locatinginputs control panel 110 may positioninputs wash tub 121. - 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.
