Description
FIELD OF THE INVENTION

The present subject matter relates generally to laundry treatment appliances, and more particularly to methods for washing ice hockey equipment within washing machine appliances.


BACKGROUND OF THE INVENTION

Washing machine appliances generally include a cabinet which supports a tub for containing wash fluid, e.g., water and detergent, bleach and/or other wash additives. A basket is 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 or an agitation element 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.


Many articles can be washed within traditional washing machine appliances, such as clothing, towels, linens, bedding, and the like. Other items which can collect sweat, body oils, and other contaminants may be difficult to wash, such as sporting equipment. For one example, ice hockey equipment tends to collect large amounts of sweat through vigorous playing. Many hockey players do not regularly wash equipment, however, for fear of damaging the equipment or damaging the washing machine appliance through contact of hard plastic shells on the drum, the agitator, the lid, or the like. Thus, the equipment tends to develop unpleasant odors and can become a proverbial petri dish of bacteria.


Accordingly, a method of operating a traditional washing machine to wash sporting equipment such as hockey equipment would be beneficial. In particular, a method of washing ice hockey equipment effectively and without damaging the equipment or the washing machine appliance would be useful.

FIGS. 1 through 3 illustrate an exemplary embodiment of a vertical axis laundry machine appliance or laundry treatment appliance (e.g., such as a washing machine) 100. Specifically, FIGS. 1 and 2 illustrate perspective views of laundry machine appliance 100 in a closed and an open position, respectively. FIG. 3 provides a side cross-sectional view of laundry machine appliance 100. Laundry machine appliance 100 generally defines a vertical direction V, a lateral direction L, and a transverse direction T, each of which is mutually perpendicular, such that an orthogonal coordinate system is generally defined.


While described in the context of a specific embodiment of a vertical axis laundry machine, it should be appreciated that vertical axis laundry machine appliance 100 is provided by way of example only. It will be understood that aspects of the present subject matter may be used in any other suitable laundry machine appliance, such as a horizontal axis laundry machine appliance. Indeed, modifications and variations may be made to laundry machine appliance 100, including different configurations, different appearances, and/or different features while remaining within the scope of the present subject matter. For instance, laundry machine appliance 100 may be a combination washing machine and dryer appliance, a stand-alone washing machine, a dryer, or any suitable appliance capable of performing a laundry operation on a laundry load.


Laundry machine appliance 100 has a cabinet 102 that extends between a top portion 104 and a bottom portion 106 along the vertical direction V. As best shown in FIG. 3, a tub 108 is positioned within cabinet 102 and is generally configured for retaining wash fluids during an operating cycle (e.g., a washing cycle). Laundry machine appliance 100 further includes a primary dispenser 110 (FIG. 2) for dispensing wash fluid into tub 108. The term “wash fluid” refers to a liquid used for washing and/or rinsing articles during an operating cycle and may include any combination of water, detergent, fabric softener, bleach, and other wash additives or treatments. Further, it should be noted that primary dispenser 110 is provided by way of example only, and that laundry machine appliance 100 may incorporate any suitable form of detergent dispenser, including manual fill dispensers.


In addition, laundry machine appliance 100 may include one or more wash baskets 112 selectively positioned within tub 108 and generally defining one or more wash chambers 114. For instance, an opening 116 may be formed in cabinet 102 for receipt of articles for washing (e.g., for receipt of one or more removable wash baskets). More specifically, wash basket 112 (e.g., one or more) may be rotatably mounted within tub 108 such that it is rotatable about an axis of rotation A. According to the illustrated embodiment, the axis of rotation A is substantially parallel to the vertical direction V. In this regard, laundry machine appliance 100 is generally referred to as a “vertical axis” or “top load” laundry machine appliance 100. However, as noted above, it should be appreciated that aspects of the present subject matter may be used within the context of a horizontal axis or front load laundry machine appliance as well.


As illustrated, cabinet 102 of laundry machine appliance 100 has a top panel 118. Top panel 118 may define opening 116 of to permit a user access to tub 108. Laundry machine appliance 100 may further include a door 120 which is rotatably mounted to top panel 118 to permit selective access to opening 116. In particular, door 120 may selectively rotate between the closed position (as shown in FIGS. 1 and 3) and the open position (as shown in FIG. 2). In the closed position, door 120 inhibits access to tub 108 (and, selectively, one or more wash baskets 112). Conversely, in the open position, a user can access wash basket 112. A window 122 in door 120 may permit viewing of wash basket 112 when door 120 is in the closed position, e.g., during operation of laundry machine appliance 100. Door 120 also includes a handle 124 that, e.g., a user may pull and/or lift when opening and closing door 120. Further, although door 120 is illustrated as mounted to top panel 118, door 120 may alternatively be mounted to cabinet 102 or any other suitable support.


As best shown in FIGS. 2 and 3, wash basket 112 further defines a plurality of perforations 126 to facilitate fluid communication between an interior of wash basket 112 and tub 108. In this regard, wash basket 112 is spaced apart from tub 108 to define a space for wash fluid to escape wash chamber 114. During a spin cycle, wash fluid within articles of clothing and within wash chamber 114 is urged through perforations 126 wherein it may collect in a sump 128 defined by tub 108. Laundry machine appliance 100 may further include a pump assembly 130 (FIG. 3) that is located beneath tub 108 and wash basket 112 for gravity assisted flow when draining tub 108, e.g., after a wash or rinse cycle.


An impeller or agitator 132 (FIG. 3), such as a vane agitator, impeller, auger, oscillatory basket mechanism, or some combination thereof may be disposed in wash basket 112 to impart an oscillatory motion to articles and liquid in wash basket 112. More specifically, agitator 132 may extend into wash basket and assists agitation of articles disposed within wash basket 112 during operation of laundry machine appliance 100, e.g., to facilitate improved cleaning. In different embodiments, agitator 132 includes a single action element (i.e., oscillatory only), a double action element (oscillatory movement at one end, single direction rotation at the other end) or a triple action element (oscillatory movement plus single direction rotation at one end, single direction rotation at the other end). As illustrated in FIG. 3, agitator 132 and wash basket 112 are oriented to rotate about the axis of rotation A (which is substantially parallel to vertical direction V). The agitator shown in FIG. 3 (agitator 132) is merely an example, and any suitable agitator may be incorporated.


As best illustrated in FIG. 3, laundry machine appliance 100 includes a drive assembly 138 in mechanical communication with wash basket 112 to selectively rotate wash basket 112 (e.g., during an agitation or a rinse cycle of laundry machine appliance 100). In addition, drive assembly 138 may also be in mechanical communication with agitator 132. In this manner, drive assembly 138 may be configured for selectively rotating or oscillating wash basket 112 and/or agitator 132 during various operating cycles of laundry machine appliance 100.


More specifically, drive assembly 138 may generally include one or more of a drive motor 140 and a transmission assembly 142, e.g., such as a clutch assembly, for engaging and disengaging wash basket 112 and/or agitator 132. According to the illustrated embodiment, drive motor 140 is a brushless DC electric motor, e.g., a pancake motor. However, according to alternative embodiments, drive motor 140 may be any other suitable type of motor. For example, drive motor 140 may be an AC motor, an induction motor, a permanent magnet synchronous motor, or any other suitable type of motor. In addition, drive assembly 138 may include any other suitable number, types, and configurations of support bearings or drive mechanisms.


Laundry appliance 100 may include one or more sensors or means for determining a laundry load size provided within wash basket 112. According to one example, a laundry load size or weight may be determined by driving drive motor 140 at a predetermined speed and detecting a basket speed and load output of drive motor 140. For instance, obtaining the basket speed of the wash basket may include measuring a motor frequency, a back electromotive force (EMF) on the motor, or a motor shaft speed (e.g., using a tachometer). It should be appreciated that other systems and methods for monitoring motor power and/or basket speeds may be used while remaining within the scope of the present subject matter.


Referring to FIGS. 1 through 3, a control panel 150 with at least one input selector 152 (FIG. 1) extends from top panel 118. Control panel 150 and input selector 152 collectively form a user interface input for operator selection of machine cycles and features. A display 154 of control panel 150 indicates selected features, operation mode, a countdown timer, and/or other items of interest to appliance users regarding operation.


Operation of laundry machine appliance 100 is controlled by a controller or processing device 156 that is communicatively coupled with control panel 150 for user manipulation to select washing machine cycles and features. In response to user manipulation of control panel 150, controller 156 operates the various components of laundry machine appliance 100 to execute selected machine cycles and features. Controller 156 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 methods described herein. Alternatively, controller 156 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 150 and other components of laundry machine appliance 100 may be in communication with controller 156 via one or more signal lines or shared communication busses.


Referring to FIG. 3, laundry machine appliance 100 includes a water supply conduit 160 that provides fluid communication between a water supply source 162 (such as a municipal water supply) and a discharge nozzle 164 for directing a flow of water into tub 108, and more specifically, into wash chamber 114. In addition, laundry machine appliance 100 includes a water fill valve or water control valve 166 which is fluidly coupled with water supply conduit 160 and communicatively coupled to controller 156. In this manner, controller 156 may regulate the operation of water control valve 166 to regulate the amount of water within tub 108.


Laundry appliance 100 may include a camera assembly configured to capture one or more images of an interior of wash basket 112. Controller 156 may be programmed or configured for analyzing the images obtained by the camera assembly, e.g., in order to determine the level or amount of a laundry load provided within wash chamber 114 or other cycle information, and may use this information to make informed decisions (e.g., regarding the operation of washing machine appliance 100 or regarding details of the laundry loads provided therein). For instance, the camera assembly may include one or more digital cameras capable of capturing still images, video images, or the like. The camera assembly may be attached to cabinet 102, door 120, or the like. As such, the camera may be provided within wash chamber 114, external to appliance 100, or any other suitable location.


Referring still to FIG. 3, a schematic diagram of an external communication system 170 will be described according to an exemplary embodiment of the present subject matter. In general, external communication system 170 is configured for permitting interaction, data transfer, and other communications between appliance 100 and one or more external devices. For example, this communication may be used to provide and receive operating parameters, user instructions or notifications, performance characteristics, user preferences, or any other suitable information for improved performance of appliance 100. In addition, it should be appreciated that external communication system 170 may be used to transfer data or other information to improve performance of one or more external devices or appliances and/or improve user interaction with such devices.


For example, external communication system 170 permits controller 156 of appliance 100 to communicate with a separate device (or multiple separate devices) external to appliance 100, referred to generally herein as an external device 172. For instance, multiple external devices 172 (e.g., a first mobile device belonging to a first user, a second mobile device belonging to a second user, etc.) may selectively communicate with appliance 100 via external communication system 170. As described in more detail below, these communications may be facilitated using a wired or wireless connection, such as via a network 174. In general, one or more external devices 172 may include any suitable devices separate from appliance 100 that are configured to provide and/or receive communications, information, data, or commands from a user or users. In this regard, external device 172 may be, for example, a personal phone, a smartphone, a tablet, a laptop or personal computer, a wearable device, a smart home system, or another mobile or remote device. Additionally or alternatively, external device 172 may include a camera 178. Camera 178 may be configured to capture one or more images (e.g., still images, video clips, burst images, etc.).


In addition, a remote server 176 may be in communication with appliance 100 and/or external device 172 through network 174. In this regard, for example, remote server 176 may be a cloud-based server, and thus may be located at a distant location, such as in a separate state, country, etc. According to an exemplary embodiment, external device 172 communicates with a remote server 176 over network 174, such as the Internet, to transmit/receive data or information, provide user inputs, receive user notifications or instructions, interact with or control appliance 100, etc. In addition, external device 172 and remote server 176 may communicate with appliance 100 to communicate similar information.


In general, communication between appliance 100, external device 172, remote server 176, and/or other user devices or appliances may be carried using any type of wired or wireless connection and using any suitable type of communication network, non-limiting examples of which are provided below. For example, external device 172 may be in direct or indirect communication with appliance 100 through any suitable wired or wireless communication connections or interfaces, such as network 174. For example, network 174 may include one or more of a local area network (LAN), a wide area network (WAN), a personal area network (PAN), the Internet, a cellular network, any other suitable short- or long-range wireless networks, etc. In addition, communications may be transmitted using any suitable communications devices or protocols, such as via Wi-Fi®, Bluetooth®, Zigbee®, wireless radio, laser, infrared, Ethernet type devices and interfaces, etc. In addition, such communication may use a variety of communication protocols (e.g., TCP/IP, HTTP. SMTP, FTP), encodings or formats (e.g., HTML, XML), and/or protection schemes (e.g., VPN, secure HTTP, SSL).


External communication system 170 is described herein according to an exemplary embodiment of the present subject matter. However, it should be appreciated that the exemplary functions and configurations of external communication system 170 provided herein are used only as examples to facilitate description of aspects of the present subject matter. System configurations may vary, other communication devices may be used to communicate directly or indirectly with one or more associated appliances, other communication protocols and steps may be implemented, etc. These variations and modifications are contemplated as within the scope of the present subject matter.



FIG. 4 provides a flowchart illustrating a method 200 of operating a laundry machine (e.g., laundry machine 100) according to an exemplary embodiment of the present disclosure. For instance, method 200 outlines at least one method for washing ice hockey equipment (e.g., shin pads, pants, girdles, shoulder pads, elbow pads, gloves, etc.) within a traditional washing machine appliance. FIG. 4 provides a non-exhaustive method of operation, and the method may include more or fewer steps than shown in FIG. 4, according to specific embodiments. Additionally or alternatively, the steps detailed in method 200 may be performed in any suitable order.


Method 200 may be initiated by a user. For instance, a user may place a laundry load within the basket (or drum) of the washing machine. According to the embodiments described herein, the laundry load may include athletic gear, such as padding. The gear or equipment may be ice hockey equipment. For instance, such hockey equipment items may include shin pads, pants, girdles, shoulder or chest pads, elbow pads, wrist guards, neck guards, gloves, under garments, or the like. Accordingly, the laundry load may include equipment composed of dense foam, light foam, hard plastics, elastics, hook-and-loop connectors, synthetic materials, waterproof or water-resistant materials, moisture wicking materials, and the like.


Method 200 may include determining a load size of the laundry load within the wash basket. One of a plurality of methods may be incorporated for determining the load size of the laundry load. For instance, the load size may be determined according to a power draw required for the motor to rotate the drum within the tub. For another example, a weight of the laundry load within the drum is determined according to one or more weight sensors. Additional or alternative methods may be incorporated for determining the load size of the laundry load. Accordingly, an appropriate or matching amount of detergent to be added may be determined according to the load size. For instance, method 200 may retrieve a corresponding detergent dispense amount based on the determined load size (e.g., from a lookup table). Additionally or alternatively, the corresponding detergent dispense amount may be calculated according to the load size.


At step 202, method 200 may include supplying a first predetermined volume of water to articles within the wash chamber. In detail, after determining the load size of the laundry load, the first predetermined volume of water may be supplied to the wash chamber (e.g., to wet the articles of the laundry load). The first predetermined volume of water may be based on the load size of the laundry load. For instance, the first predetermined volume of water may be sufficient to thoroughly wet the articles within the wash chamber. Thus, the first predetermined volume of water is less than a maximum volume of the wash chamber. Additionally or alternatively, the first predetermined volume of water may be limited such that the laundry load (e.g., the hockey equipment) remains in contact with an agitator provided within the wash chamber (e.g., an agitator tower, an agitator vane, etc.).


At step 204, method 200 may include soaking the articles in the first predetermined volume of water for a first predetermined time period. In detail, upon supplying the first predetermined volume of water to the wash chamber, the method 200 may pause any further actions for the first predetermined time period. For example, during the soak period, no agitation occurs (e.g., the drum and/or agitator are not rotated), no detergent is supplied, etc. Accordingly, the articles (e.g., the equipment) may soak within the first predetermined volume of water. During the soaking period, the articles may begin to retain (e.g., absorb or soak) the water within the wash chamber. For instance, some of the more water-resistant fabrics or materials may utilize the soaking period to absorb water for future cycles. According to at least some embodiments, the first predetermined time period is between about 5 minutes and about 10 minutes. However, the range given is provided by way of example only, and the first predetermined time period may be less than or greater than the examples provided herein.


At step 206, method 200 may include supplying a second predetermined volume of water to the articles within the wash chamber after the first predetermined time period. The second predetermined volume of water may be added in addition to the first predetermined volume of water. For instance, the first predetermined volume of water may not be drained, extracted, or otherwise removed from the wash chamber prior to adding the second predetermined volume of water. Accordingly, the first predetermined volume of water and the second predetermined volume of water may form a first fill volume of water. Thus, the first fill volume of water may be greater than each of the first predetermined volume of water and the second predetermined volume of water. At this point, the articles (e.g., the equipment) may be submerged within the first fill volume of water.


At step 208, method 200 may include supplying a detergent to the wash chamber together with the second predetermined volume of water. For instance, steps 206 and 208 may be performed concurrently. In detail, as the second predetermined volume of water is added to the wash chamber, the determined amount of detergent may also be supplied to the wash chamber. The detergent may be supplied to the wash chamber via an automatic dosing system. For one example, the determined amount of detergent is retrieved from a bulk detergent dispenser and supplied to the wash chamber along with the second predetermined volume of water. According to additional or alternative embodiments, the determined amount of detergent is supplied to the wash chamber from a detergent chamber, cup, assembly, or other known additive system provided within the appliance. Further still, the detergent may be added to the wash chamber manually (e.g., by a user). For instance, a user may be alerted that the detergent is required (e.g., via an on board notification, a remote notification, or the like). Accordingly, the first fill volume of water within the wash chamber may include the determined amount of detergent.


At step 210, method 200 may include performing a first agitation cycle. In detail, the first agitation cycle may include the first fill volume of water and the determined amount of detergent. The first agitation cycle may include one or more agitation motions or movements (e.g., a rotation of the drum, a rotation of the agitator, etc.). The first agitation cycle may be performed for a predetermined agitation time period (e.g., a predetermined first agitation time period). For instance, the predetermined agitation time period may be between about 10 minutes and about 20 minutes. However, it should be noted that the times provided herein are mentioned by way of example only, and that any suitable time period may be incorporated for the agitation time period.


The first agitation cycle may be referred to as a mechanical agitation cycle. For instance, as the first agitation cycle includes the first fill volume of water, the wash chamber may be considered to be at a medium fill level. As mentioned above, the wash articles (e.g., equipment) may be saturated within the wash chamber. Generally, the equipment pieces may be in mechanical contact with the agitator means provided within the wash chamber (e.g., an agitator post, a rotating vane, an impeller, an auger, etc.). The first agitation cycle may thus incorporate a physical wash parameter to the equipment. According to some embodiments, an agitation intensity may be adjusted for the first agitation cycle. For instance, a rotation speed of one or more of the drum, the agitator, or both may be adjusted (e.g., from a normal setting) for the first agitation cycle. Due to the increased physical or mechanical interaction between the equipment and the appliance, a lower intensity agitation may be incorporated. For at least one example, a controller reduces the rotational speed of the basket and/or agitator according to the determined load size of the wash articles (e.g., equipment).


Subsequent to performing the first agitation cycle, the method 200 may include an additional soak cycle. In detail, after completing the first agitation cycle, the method 200 may pause any further actions for a predetermined time period. For example, during the additional (or subsequent) soak period, no agitation occurs (e.g., the drum and/or agitator are not rotated), no detergent is supplied, etc. Accordingly, the articles (e.g., the equipment) may soak within the first fill volume of water together with the determined amount of detergent (e.g., as supplied in step 208). During the additional soaking period, the articles may retain (e.g., absorb or soak) the water together with the detergent within the wash chamber. Similar to the soak cycle described at step 204, the additional soak cycle may be performed for the first predetermined time period (e.g., between about 5 minutes and about 10 minutes). However, the time period for the additional soak period may be less than or greater than the first predetermined time period.


At step 212, method 200 may include supplying a third predetermined volume of water to the articles within the wash chamber. The third predetermined volume of water may be supplied after performing the additional soak cycle, for instance. Moreover, the third predetermined volume of water may be supplied after performing the first agitation cycle. The third predetermined volume of water may be added in addition to the first predetermined volume of water and the second predetermined volume of water (e.g., the first fill volume of water). For instance, the first fill volume of water (and detergent) may not be drained, extracted, or otherwise removed from the wash chamber prior to adding the third predetermined volume of water. Accordingly, the first fill volume of water and the third predetermined volume of water may form a second fill volume of water. Thus, the second fill volume of water may be greater than each of the first predetermined volume of water, the second predetermined volume of water, and the third predetermined volume of water. At this point, the articles (e.g., the equipment) may be fully submerged within the second fill volume of water (i.e., the drum or tub is considered to be at a maximum fill volume).


At step 214, method 200 may include performing a second agitation cycle. The second agitation cycle may include the second fill volume of water. The second agitation cycle may include one or more agitation motions or movements (e.g., a rotation of the drum, a rotation of the agitator, etc.). The second agitation cycle may be performed for a predetermined agitation time period (e.g., a predetermined second agitation time period). For instance, the predetermined agitation time period may be between about 10 minutes and about 20 minutes. In some instances, the predetermined second agitation time period is equal to the predetermined first agitation time period. However, it should be noted that the times provided herein are mentioned by way of example only, and that any suitable time period may be incorporated for the agitation time period.


The second agitation cycle may be referred to as a gentle agitation cycle. For instance, as the second agitation cycle includes the second fill volume of water (e.g., the maximum fill volume), the wash chamber may be considered to be at a full fill level. As mentioned above, the wash articles (e.g., equipment) may be fully submerged within the wash chamber. Due to the typical construction of ice hockey equipment, however, some of the pieces may be buoyant within the second fill volume of water (e.g., some pieces may float). Accordingly, some equipment pieces may be suspended within the wash chamber (e.g., not in direct contact with any mechanical pieces within the wash chamber). The second agitation cycle may thus incorporate a gentle wash parameter to the equipment.


According to some embodiments, the agitation intensity may be adjusted for the second agitation cycle. For instance, a rotation speed of one or more of the drum, the agitator, or both may be adjusted (e.g., from the normal setting or from the mechanical setting mentioned above) for the second agitation cycle. Due to the decreased physical or mechanical interaction between the equipment and the appliance, a higher intensity agitation may be incorporated. For at least one example, a controller increases the rotational speed of the basket and/or agitator according to the determined load size of the wash articles (e.g., equipment). Thus, the water (and detergent) within the wash chamber may be the principle washing action on the equipment.


Method 200 may include draining the second fill volume of water from the tub after performing the second agitation cycle. In detail, upon completion of the second agitation cycle, the appliance (e.g., via the controller) may activate or open a drain valve to remove or drain the second fill volume of water (and detergent) from the wash chamber (or tub). While draining the second fill volume of water, the method 200 may include rotating the drum at a predetermined drain speed. For instance, the drum may be rotated at a low (e.g., under 100 revolutions per minute [RPM]) speed. Accordingly, the draining of the second fill volume of water may be accelerated.



FIG. 5 provides a flowchart illustrating a method 300 of operating a laundry machine (e.g., laundry machine 100) according to an exemplary embodiment of the present disclosure. FIG. 4 provides a non-exhaustive method of operation, and the method may include more or fewer steps than shown in FIG. 4, according to specific embodiments. For instance, method 300 may be performed immediately before, immediately after, or each of before and after method 200 described above. For one example, method 300 is immediately performed after the second fill volume of water is drained from the tub.


At step 302, method 300 may include supplying a first predetermined rinse volume of water to the articles within the wash chamber. As mentioned above, the first predetermined rinse volume of water may be supplied after the second fill volume of water is drained from the tub. The first predetermined rinse volume of water may be similar (e.g., approximately equal) to the first predetermined volume of water (e.g., from step 202). For instance, the first predetermined rinse volume of water may be supplied to the wash chamber (e.g., to the articles of the laundry load). The first predetermined rinse volume of water may be based on the load size of the laundry load. For instance, the first predetermined rinse volume of water may be sufficient to thoroughly wet the articles within the wash chamber. Thus, the first predetermined rinse volume of water is less than a maximum volume of the wash chamber. Additionally or alternatively, the first predetermined rinse volume of water may be limited such that the laundry load (e.g., the hockey equipment) remains in contact with the agitator provided within the wash chamber.


At step 304, method 300 may include performing a first rinse agitation cycle after supplying the first predetermined rinse volume of water. In detail, the first rinse agitation cycle may include the first predetermined rinse volume of water. It should be noted that no additional detergent may be added during the first rinse agitation cycle. The first rinse agitation cycle may include one or more agitation motions or movements (e.g., a rotation of the drum, a rotation of the agitator, etc.). The first rinse agitation cycle may be performed for a predetermined agitation time period (e.g., a predetermined first rinse agitation time period). For instance, the predetermined agitation time period may be between about 10 minutes and about 20 minutes. However, it should be noted that the times provided herein are mentioned by way of example only, and that any suitable time period may be incorporated for the agitation time period.


The first rinse agitation cycle may be referred to as a mechanical agitation cycle. For instance, as the first rinse agitation cycle includes the first predetermined rinse volume of water, the wash chamber may be considered to be at a medium (or low) fill level. As mentioned above, the wash articles (e.g., equipment) may be saturated within the wash chamber. Generally, the equipment pieces may be in mechanical contact with the agitator means provided within the wash chamber (e.g., an agitator post, a rotating vane, an impeller, an auger, etc.). The first rinse agitation cycle may thus incorporate a physical wash parameter to the equipment. According to some embodiments, an agitation intensity may be adjusted for the first rinse agitation cycle. For instance, a rotation speed of one or more of the drum, the agitator, or both may be adjusted (e.g., from a normal setting) for the first rinse agitation cycle. Due to the increased physical or mechanical interaction between the equipment and the appliance, a lower intensity agitation may be incorporated. For at least one example, a controller reduces the rotational speed of the basket and/or agitator according to the determined load size of the wash articles (e.g., equipment).


At step 306, method 300 may include supplying a second predetermined rinse volume of water to the articles within the wash basket. The second predetermined rinse volume of water may be added in addition to the first predetermined rinse volume of water. For instance, the first predetermined rinse volume of water may not be drained, extracted, or otherwise removed from the wash chamber prior to adding the second predetermined rinse volume of water. Accordingly, the first predetermined rinse volume of water and the second predetermined rinse volume of water may form a total rinse volume of water. Thus, the total rinse volume of water may be greater than each of the first predetermined rinse volume of water and the second predetermined rinse volume of water. At this point, the articles (e.g., the equipment) may be submerged within the total rinse volume of water.


At step 308, method 300 may include performing a second rinse agitation cycle after supplying the second predetermined rinse volume of water. The second rinse agitation cycle may include the total rinse volume of water. The second rinse agitation cycle may include one or more agitation motions or movements (e.g., a rotation of the drum, a rotation of the agitator, etc.). The second rinse agitation cycle may be performed for a predetermined agitation time period (e.g., a predetermined second rinse agitation time period). For instance, the predetermined agitation time period may be between about 10 minutes and about 20 minutes. In some instances, the predetermined second rinse agitation time period is equal to the predetermined first rinse agitation time period. However, it should be noted that the times provided herein are mentioned by way of example only, and that any suitable time period may be incorporated for the agitation time period.


The second rinse agitation cycle may be referred to as a gentle agitation cycle. For instance, as the second rinse agitation cycle includes the total rinse volume of water, the wash chamber may be considered to be at a full fill level. As mentioned above, the wash articles (e.g., equipment) may be fully submerged within the wash chamber. Due to the typical construction of ice hockey equipment, however, some of the pieces may be buoyant within the total rinse volume of water (e.g., some pieces may float). Accordingly, some equipment pieces may be suspended within the wash chamber (e.g., not in direct contact with any mechanical pieces within the wash chamber). The second rinse agitation cycle may thus incorporate a gentle wash parameter to the equipment.


According to some embodiments, the agitation intensity may be adjusted for the second rinse agitation cycle. For instance, a rotation speed of one or more of the drum, the agitator, or both may be adjusted (e.g., from the normal setting or from the mechanical setting mentioned above) for the second rinse agitation cycle. Due to the decreased physical or mechanical interaction between the equipment and the appliance, a higher intensity agitation may be incorporated. For at least one example, a controller increases the rotational speed of the basket and/or agitator according to the determined load size of the wash articles (e.g., equipment). Thus, the water (and detergent) within the wash chamber may be the principle washing (or rinsing) action on the equipment.


Subsequent to performing the second rinse agitation cycle, the method 300 may include draining the total rinse volume of water from the tub. In detail, upon completion of the second rinse agitation cycle, the appliance (e.g., via the controller) may activate or open a drain valve to remove or drain the total rinse volume of water from the wash chamber (or tub). While draining the total rinse volume of water, the method 300 may include rotating the drum at a predetermined drain speed. For instance, the drum may be rotated at a low (e.g., under 100 RPM) speed. Accordingly, the draining of the second fill volume of water may be accelerated.


The method 300 may include performing a spin extraction cycle after draining the total rinse volume of water from the tub. In detail, method 300 may accelerate the drum subsequent to draining the total rinse volume in order to extract any excess or trapped water from the equipment. The spin extraction cycle may thus include rotating the drum at a predetermined extraction speed for a spin cycle time. As mentioned above, the wash articles (e.g., the hockey equipment) may include certain materials such as hard plastics and dense foams, which may be susceptible to damage or deformation within the laundry appliance. Accordingly, the spin extraction cycle may be performed at a predetermined rotational speed that is relatively low (e.g., as compared to a normal spin extraction cycle for a normal washing operation). For at least one example, the spin extraction cycle is performed at a rotational speed of between about 400 RPM and about 500 RPM. Additionally or alternatively, the spin extraction cycle may be performed for a time period of between about 5 minutes and about 10 minutes. It should be noted that the ranges provided herein are by way of example, and any suitable rotational speed and duration may be incorporated according to specific embodiments.
