The present subject matter relates generally to washing machine appliances and more particularly to washing machine appliances having a pretreat cover.
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.
One issue with many conventional washing machine appliances is that consumers have no place to pretreat articles before washing. In many conventional washing machine appliances, there is not an adequate surface or component on which to perform pretreat activities. Accordingly, such activities must be performed in a separate utility sink, a kitchen sink, or in another suitable location using apparatus separate from the washing machine appliance. This can be inconvenient and time-consuming for the consumer.
Accordingly, improved apparatus for allowing convenient pre-treatment options in association with washing machine appliances are desired.
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.
A washing machine appliance is provided. The washing machine appliance defines vertical, lateral, and transverse directions, and may include a cabinet comprising a top panel that defines an opening. A tub may be positioned within the cabinet, and a wash basket may be rotatably mounted within the tub. Further, the wash basket may define a wash chamber for receiving articles for washing. A door of the washing machine appliance may be rotatably mounted to the top panel to permit selective access to the opening, and the door may be rotatable between an open position and a closed position. The washing machine appliance may also include a pretreat cover that is movable between a stowed position and a deployed position. In one embodiment, the pretreat cover may be a board that is rotatable between the deployed and stowed positions. In another embodiment, the pretreat cover may be a flexible screen that is movable between the deployed and stowed positions. The pretreat cover may be spaced apart from the opening when in the stowed position. In contrast, the pretreat cover may be at least partially disposed in the opening when in the deployed position.
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.
A full and enabling disclosure of the present invention, including the best mode thereof, directed to one of ordinary skill in the art, is set forth in the specification, which makes reference to the appended figures.
Reference now will be made in detail to embodiments of the invention, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present invention covers such modifications and variations as come within the scope of the appended claims and their equivalents.
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 axis washing 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 a cabinet 102 that extends between a top portion 103 and a bottom portion 104 along the vertical direction V. A wash basket 120 (
Cabinet 102 of washing machine appliance 100 has a top panel 140. Top panel 140 defines an opening 105 (
A control panel 110 with at least one input selector 112 (
Operation of washing machine appliance 100 is controlled by a controller or processing device 108 (
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 of washing machine appliance 100 may be in communication with controller 108 via one or more signal lines or shared communication busses.
During operation of washing machine appliance 100, laundry items are loaded into wash basket 120 through opening 105, and washing operation is initiated through operator manipulation of input selectors 112. Wash basket 120 is filled with water and detergent and/or other fluid additives via additive dispenser 200, which will be described in detail below. One or more valves can be controlled by washing machine appliance 100 to provide for filling wash 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 wash basket 120 is properly filled with fluid, the contents of wash basket 120 can be agitated (e.g., with an impeller as discussed previously) for washing of laundry items in wash 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 wash basket 120 depending on the specifics of the cleaning cycle selected by a user. The impeller may again provide agitation within wash 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, wash basket 120 is rotated at relatively high speeds. After articles disposed in wash basket 120 are cleaned and/or washed, the user can remove the articles from wash basket 120, e.g., by reaching into wash basket 120 through opening 105.
Referring now generally to
Additive dispenser 200 is a box having a substantially rectangular cross-section that defines a top 202 and a bottom 204 spaced apart along the vertical direction V. Additive dispenser 200 also defines a front side 206 and a back side 208 spaced apart along the transverse direction T. As best shown in
Additive dispenser 200 may define a mixing chamber 220 configured to receive one or more additive compartments. For example, according to the illustrated embodiment, mixing chamber 220 may be configured to slidably receive a detergent compartment 222 and a softener compartment 224. Compartments 222, 224 are slidably connected to the mixing chamber 220 using slides 226 and are connected to a front panel 228 of additive dispenser. In this manner, a user may pull on front panel 228 to slide compartments 222, 224 along the transverse direction T. Once extended, detergent compartment 222 and softener compartment 224 may be conveniently filled with detergent and softener, respectively. Front panel 228 may be then be pushed back into mixing chamber 220 before a wash cycle begins.
Although the illustrated embodiment shows detergent compartment 222 and softener compartment 224 slidably received in mixing chamber 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 mixing chamber 220. Alternatively, mixing chamber 220 may draw wash additives from a separate storage container such that sliding compartments 222, 224 are not needed. Other configurations of mixing chamber 220 and compartments 222, 224 are also possible and within the scope of the present subject matter.
Additive dispenser 200 may further include a plurality of valves configured to supply hot and cold water to mixing chamber 220 or directly to wash tub 121. For example, according to the illustrated embodiment, a plurality of apertures may be defined on top 202 of mixing chamber 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 into detergent compartment 222. A second valve seat 236 may be in fluid communication with a second aperture for providing cold water into detergent compartment 222. A third valve seat 238 may be in fluid communication with a third aperture for providing cold water into softener compartment 224. A fourth valve seat 240 may be in fluid communication with a fourth aperture for providing cold water into mixing chamber 220 or directly into wash tub 121.
Water inlets may be placed in fluid communication with each of valve seats 234, 236, 238, 240. More specifically, a hot water inlet 244 may be connected to a hot water supply line (not shown) and a cold water inlet 246 may be connected to a cold water supply line (not shown). According to the illustrated embodiment, each water inlet 244, 246 may include a threaded male adapter configured for receiving a threaded female adapter from a conventional water supply line. However, any other suitable manner of fluidly connecting a water supply line and water inlets 244, 246 may be used. For example, each water supply line and water inlets 244, 246 may have copper fittings that may be sweated together to create a permanent connection.
Notably, hot water inlet 244 is in direct fluid communication with first valve seat 234. However, because washing machine appliance 100 uses cold water for multiple purposes, cold water inlet is in fluid communication with a cold water manifold 248. Cold water manifold 248 may be a cylindrical pipe that extends along the lateral direction from second valve seat 236 to fourth valve seat 240. In this manner, cold water manifold 248 places valve seats 236, 238, and 240 in fluid communication with cold water inlet 246.
Each of valve seats 234, 236, 238, 240 may be configured to receive a water valve 252 for controlling the flow of water through a corresponding aperture into mixing chamber 220. Water valve 252 may be, for example, a solenoid valve that is electrically connected to controller 108. However, any other suitable water valve may be used to control the flow of water. Controller 108 may selectively open and close water valves 252 to allow water to flow from hot water inlet 244 through first valve seat 234 and from cold water manifold 248 through one or more of second valve seat 236, third valve seat 238, and fourth valve seat 240.
Additive dispenser 200 may further include one or more nozzles (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 into wash tub 121 from additive dispenser 200. For example, when second valve seat 236 is open, water may flow from cold water inlet 246 through cold water manifold 248 and second valve seat 236 into detergent compartment 222. Water may mix with detergent placed in detergent compartment 222 to create wash liquid to be dispensed into wash tub 121.
A nozzle (not shown) may be placed on the bottom of detergent compartment 222 or on the bottom of mixing chamber 220 to dispense the wash fluid into wash tub 121. According to the illustrated embodiment, additive dispenser 200 may include four nozzles associated with valves seats 234, 236, 238, 240, respectively. However, it will be understood that different nozzle configurations may be used in alternative exemplary embodiments. For example, nozzles may be positioned on a bottom of mixing chamber 220 near wash tub 121 or directly on wash tub 121, but could be positioned in other locations as well.
As discussed herein, in some situations, a user may wish to cause the flow of water separate from the flows associated with typical wash cycles. For example, a user may wish to obtain water for use when pretreating articles in a wash basin, as discussed herein. The user may thus utilize a suitable input selector 112 or other dedicated input to cause water to be flowed on-demand and independently of the typical wash cycles of the washing machine appliance 100.
As will be discussed below in more detail, the washing machine appliance 100 may include a pretreat cover that may advantageously be movable to and from a deployed position in which the pretreat cover can be utilized by a user for pretreating needs, such as scrubbing, treating, etc. When in the deployed position, the pretreat cover may further advantageously be sized to provide adequate surface area for pretreating needs while not completely blocking access to the washing basket 120 through the opening 105. The pretreat cover may further advantageously be movable to and from a stowed position in which the pretreat cover is out of the way and does not impede with the user's access to the wash basket 120 through the opening 105.
In some embodiments, the pretreat cover may be a board (

In alternative embodiments, the board 300 may define a drain hole 340 (
The board 300 may define an aperture 350 extending therethrough along the vertical direction V. In particular, the aperture 350 may extend through both the top and bottom surfaces 306, 308 along the vertical direction V. In some embodiments, the board 300 may be rotatably connected to the top panel 140 via a support member 360 extending through the aperture 350 along the vertical direction V. In some embodiments, the support member 360 may be integrally formed with the top panel 140 as a single unitary component. Regardless, it should be appreciated that the board 300 may rotate relative to the support member 360. In particular, the board 300 may rotate between the deployed (

When in the stowed position, at least a portion of the flexible screen 400 may be spooled within a housing 410 that is positioned beneath an upper surface 142 of the top panel 140 along the vertical direction V. More specifically, the housing 410 may be positioned between the upper surface 142 and the wash basket 120 along the vertical direction V. The housing 410 may define an opening 412 (
The flexible screen 400 may also include a latch 420. As shown, the latch 420 may be attached to the flexible screen 400 via one or more mechanical fasteners 422. It should be appreciated, however, that the latch 420 may be attached to the flexible screen 400 via any suitable method. Alternatively, the latch 420 may be integrally formed with the flexible screen 400 as a singular component.
As the flexible screen 400 moves from the stowed position (
The flexible screen 400 may define a plurality of apertures 430. Further, each aperture of the plurality of apertures 430 may be in fluid communication with the wash basket 120 when the flexible screen 400 is in the deployed position. Accordingly, water used to pretreat articles of clothing laid on the flexible screen 400 may drain into the wash basket 120 through the plurality of apertures 430.
