Description

FIELD OF THE INVENTION

The present subject matter relates generally to appliances and more particularly to a flexible cover member for providing selective access to an opening of an appliance.

BACKGROUND OF THE INVENTION

Washing machine appliances generally include a tub for containing wash fluid, e.g., water, detergent, and/or bleach. A basket is rotatably mounted within the tub and defines a wash chamber for receipt of articles for washing. During operation of such washing machine appliances, wash fluid is directed into the tub and onto articles within the wash chamber of the basket. The basket can rotate at various speeds to agitate articles within the wash chamber in the wash fluid, to wring wash fluid from articles within the wash chamber, etc. For example, during operation of certain washing machine appliances, a spin cycle is performed to wring wash fluid from the articles within the wash chamber. The spin cycle typically entails rotating the basket at a relatively high rate of speed for a period of time. Typically, and desirably, the tub is generally empty of wash fluid and suds (caused by interaction between water and detergent, etc.). Washing machine appliances also typically include a rigid top lid (or rigid front door) for securing the articles within the wash chamber and for preventing the articles, as well as the water and detergent, from exiting the wash chamber during operation. Such appliances may also include various other compartments or chambers having various rigid doors or lids for providing selective access thereto.

Accordingly, the art is continuously seeking new and improved washing machine appliances. Thus, the present disclosure is directed to an appliance, such as a washing machine appliance, having a flexible cover member (rather than the rigid lid or door) for providing selective access to an opening of an appliance.

DETAILED DESCRIPTION

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.

Referring now to the drawings, FIG. 1 illustrates a perspective view of a washing machine appliance 50 according to an exemplary embodiment of the present subject matter. As may be seen in FIG. 1, the washing machine appliance 50 includes a cabinet 52 and a cover 54. A backsplash 56 extends from the cover 54, and a control panel 58 including a plurality of input selectors 60 is coupled to backsplash 56. The control panel 58 and input selectors 60 collectively form a user interface input for operator selection of machine cycles and features, and in one embodiment, a display 76 indicates selected features, a countdown timer, and/or other items of interest to machine users. A lid 62 is mounted to the cover 54 and is rotatable between an open position (not shown) facilitating access to a wash tub 64 (FIG. 2) located within the cabinet 52 and a closed position (shown in FIG. 1) forming an enclosure over the tub 64.

Referring now to FIG. 2, a front, cross-sectional view of the washing machine appliance 50 is illustrated. As may be seen in FIG. 2, the tub 64 includes a bottom wall 66 and a sidewall 68. A wash basket or wash drum 70 is rotatably mounted within the tub 64. In exemplary embodiments as shown, the basket 70 is rotatable about a vertical axis V. Thus, the washing machine appliance 50 in these embodiments is generally referred to as a vertical axis washing machine appliance. Further, as shown, the basket 70 defines a wash chamber 73 for receipt of articles for washing and extends, e.g., vertically, between a bottom portion 80 and a top portion 82. The basket 70 includes a plurality of openings or perforations 71 therein to facilitate fluid communication between an interior of the basket 70 and the tub 64.

A spout 72 is configured for directing a flow of fluid into the tub 64. In particular, the spout 72 may be positioned at or adjacent to the top portion 82 of the basket 70. The spout 72 may be in fluid communication with a water supply (not shown) in order to direct fluid (e.g., liquid water) into the tub 64 and/or onto articles within the chamber 73 of the basket 70. A valve 74 regulates the flow of fluid through the spout 72. For example, the valve 74 can selectively adjust to a closed position in order to terminate or obstruct the flow of fluid through the spout 72. A pump assembly 90 (shown schematically in FIG. 2) is located beneath the tub 64 and the basket 70 for gravity assisted flow to drain the tub 64.

Still referring to FIG. 2, an agitation element 92, shown as an impeller in FIG. 2, is disposed in the basket 70 to impart an oscillatory motion to articles and liquid in the chamber 73 of the basket 70. In various embodiments, the agitation element 92 includes a single action element (i.e., oscillatory only), double action (oscillatory movement at one end, single direction rotation at the other end) or triple action (oscillatory movement plus single direction rotation at one end, singe direction rotation at the other end). As illustrated in FIG. 2, the agitation element 92 is oriented to rotate about vertical axis V. The basket 70 and the agitation element 92 are driven by a pancake motor 94. Thus, as a motor output shaft 98 is rotated, the basket 70 and the agitation element 92 are operated for rotatable movement within the tub 64, e.g., about vertical axis V. Further, the washing machine appliance 50 may also include a brake assembly (not shown) selectively applied or released for respectively maintaining the basket 70 in a stationary position within the tub 64 or for allowing the basket 70 to spin within the tub 64.

Operation of the washing machine appliance 50 is controlled by a processing device or controller 78, that is operatively coupled to the user interface input located on washing machine backsplash 56 (shown in FIG. 1) for user manipulation to select washing machine cycles and features. As such, in response to user manipulation of the user interface input, the controller 78 operates the various components of the washing machine appliance 50 to execute selected machine cycles and features.

The controller 78 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 78 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 58 and other components of washing machine appliance 50 may be in communication with controller 78 via one or more signal lines or shared communication busses.

In an illustrative embodiment, laundry items are loaded into the chamber 73 of the basket 70, and washing operation is initiated through operator manipulation of control input selectors 60. The tub 64 is filled with water and mixed with detergent to form a wash fluid. The valve 74 can be opened to initiate a flow of water into the tub 64 via the spout 72, and the tub 64 can be filled to the appropriate level for the number of articles being washed. In certain embodiments, the detergent may be poured directly into the basket 70 via a user. In alternative embodiments, the washing machine appliance 50 may be further equipped with a detergent dispenser 84 (FIG. 2) in which the detergent may be poured. In certain embodiments, as an example, the dispenser 84 may be a smart dispenser than can be controlled via the controller 78 as further described herein. Once the tub 64 is properly filled with wash fluid, the contents of the basket 70 are agitated with the agitation element 92 for cleaning of laundry items in the basket 70. More specifically, the agitation element 92 is moved back and forth in an oscillatory motion.

After the agitation phase of the wash cycle is completed, the tub 64 is drained. Laundry articles can then be rinsed by again adding fluid to the tub 64, depending on the particulars of the cleaning cycle selected by a user, the agitation element 92 may again provide agitation within the basket 70. One or more spin cycles may also be used. In particular, a spin cycle may be applied after the wash cycle and/or after the rinse cycle in order to wring wash fluid from the articles being washed. During a spin cycle, the basket 70 is rotated at relatively high speeds.

While described in the context of a specific embodiment of the washing machine appliance 50, using the teachings disclosed herein it will be understood that the washing machine appliance 50 is provided by way of example only. Other washing machine appliances having different configurations (such as horizontal-axis washing machine appliances), different appearances, and/or different features may also be utilized with the present subject matter as well.

Referring still to FIG. 2, a pressure chamber 86 may be defined in the tub 64. The pressure chamber 86 may be provided for facilitating tub pressure measurements. For example, a hose 88 may connect the pressure chamber 86 to a pressure sensor 96. The pressure sensor 96 may measure the pressure in the pressure chamber 86 or at another suitable location within the tub 64, and may be in operative communication with the controller 78. The pressure sensor 96 may be a component of the controller 78, or may be a separate component from the controller 78 which is in communication with the controller 78 through a suitable wired or wireless connection. The pressure sensor 96 may, for example, be an analog pressure sensor, a digital pressure sensor, a mechanical pressure switch, or any other suitable device capable of measuring pressure as required herein.

Referring now to FIGS. 3-8, various embodiments of a cover member 100 for an appliance, such as washing machine appliance 50, are illustrated according to the present disclosure.
