[0018] Figure 1 An automatic dishwasher 10 capable of automatically operating a cycle to process dishes is shown. As used in this specification, the term "dishes" is intended to be general for any items (single or plural) that can be processed in the dishwasher 10, including but not limited to dishes, plates, cans, bowls, pans, glassware, silverware and other utensils. As shown, the dishwasher 10 is a built-in dishwasher embodiment, which is designed to be installed under a countertop. However, this description is applicable to other dishwasher embodiments, such as stand-alone, multi-liner, drawer or sink, and, for example, dishwashers with different widths, sizes and capacities. The dishwasher 10 shares many features of conventional automatic dishwashers, which may not be described in detail herein except as necessary for a complete understanding of the various aspects of the present disclosure.

[0019] The dishwasher 10 has various systems, some of which are controllable to achieve an automatic operating cycle. A housing is provided to support the various systems necessary to achieve the automatic operating cycle. As shown, for a built-in embodiment, the housing includes a frame in the form of a base 12 on which an open interior liner 14 is supported, and the open interior liner 14 at least partially defines a processing chamber 16 having an open face 18 for receiving dishes. A closure member in the form of a door assembly 20 can be hingedly or pivotally mounted to the base 12 to move between open and closed positions relative to the interior liner 14 to selectively open and close the open face 18 of the interior liner 14. In the open position, the processing chamber 16 is accessible to a user, such as Figure 1 As shown, in the closed position, the door assembly 20 covers or closes the open face 18 of the processing chamber 16. Thus, the door assembly 20 provides selective accessibility to the processing chamber 16 for loading and unloading dishes or other items.

[0020] In the case of a built-in dishwasher implementation, in addition to a dedicated frame structure such as the base 12, the cabinet can be formed by other parts of the dishwasher 10 (such as the liner 14 and the door assembly 20), which together form a single frame through which various systems can be supported. In other implementations, such as a drawer dishwasher, the cabinet can be a liner that is slidable relative to the frame, wherein the closure is a part of the cabinet or a work surface of the surrounding cabinet. In a sink-type implementation, the sink forms the liner, and a cover that closes the open top of the sink forms the closure. Sink-type implementations are more common in recreational vehicles.

[0021] The systems supported by the enclosure, while being essentially non-limiting, may include a dish holding system 30, a spray system 40, a recirculation system 50, a drainage system 60, a water supply system 70, a drying system 80, a heating system 90, and a filtration system 100. These systems are used to effect one or more treatment cycles of the dishes, of which there are many, one of which includes a conventional automatic wash cycle.

[0022] The basic conventional automatic washing operation cycle has a wash phase, in which the detergent / water mixture is recirculated and then drained, followed by a rinse phase, in which separate water or rinse agent is recirculated together and then drained. An optional drying phase may follow the rinse phase. More commonly, the automatic washing cycle has multiple wash phases and multiple rinse phases. Multiple wash phases may include a pre-wash phase, in which water is sprayed or recirculated onto the dishes with or without detergent, and may include a stay or soak phase. There may be multiple pre-wash phases. The wash phase (in which water with detergent is recirculated on the dishes) follows the pre-wash phase. There may be more than one wash phase; the number of which may be sensor-controlled based on the amount of dirt sensed in the wash liquid. One or more rinse phases will follow the wash phase, and in some cases, between the wash phases. The number of wash phases may also be sensor-controlled based on the amount of dirt sensed in the rinse liquid. The amount of water, treatment chemicals, and / or rinse aid used during each of the multiple wash or rinse steps may vary. The wash and rinse phases may include heating the water, even to the point where one or more of the phases is hot enough for a sufficient period of time to sanitize the dishes. A drying phase may follow the rinse phase. The drying phase may include drip drying, a non-heated drying step (so-called "air only"), heated drying, condensation drying, air drying, or any combination. These multiple phases or steps may also be performed by dishwasher 10 in any desired combination.

[0023] A controller 22 may also be included in the dishwasher 10 and may be operably coupled to and control various components of the dishwasher 10 to implement an operating cycle. As shown, the controller 22 may be located within the door assembly 20, or it may alternatively be located somewhere within the cabinet. The controller 22 may also be operably coupled to a control panel or user interface 24 for receiving user selected inputs and transmitting information to the user. The user interface 24 may include operating controls such as dials, lights, switches, and displays, so that a user can input commands such as operating cycles to the controller 22 and receive information, such as about the selected operating cycle.

[0024] The dish holding system 30 may include any suitable structure for receiving or holding dishes within the processing chamber 16. An exemplary dish holder is shown in the form of an upper dish rack 32 and a lower dish rack 34 (commonly referred to as a "rack"), which are located within the processing chamber 16. The upper dish rack 32 and the lower dish rack 34 define an interior and are typically mounted to be slidably moved into and out of the processing chamber 16 through the open face 18 to facilitate loading and unloading. Drawer guides / slides / rails 36 are typically used to slidably mount the upper dish rack 32 to the inner container 14. The lower dish rack 34 typically has wheels or rollers 38 that roll along rails 39 formed in the side walls of the inner container 14 and onto the door assembly 20 when the door assembly 20 is in the open position.

[0025] A special dish holder can also be provided. One such special dish holder is a third-level rack 28 located above the upper dish rack 32. Similar to the upper dish rack 32, the third-level rack is slidably mounted to the inner tank 14 using a drawer guide / slide / rail 36. The third-level rack 28 is generally used to hold utensils (such as dishes, spoons, knives, scrapers, etc.) on the side or in a planar orientation. However, the third-level rack 28 is not limited to holding utensils. If an item can be assembled in the third-level rack, it can be washed in the third-level rack 28. The third-level rack 28 generally has a much shorter height or a much lower profile than the upper dish rack 32 and the lower dish rack 34. Typically, the height of the third-level rack is short enough so that a typical glass cannot stand vertically in the third-level rack 28, and the third-level rack 28 can still slide into the processing chamber 16.

[0026] Another dedicated dish holder may be a silverware basket (not shown), which is typically carried by one of the upper dish rack 32 or the lower dish rack 34 or mounted to the door assembly 20. The silverware basket typically holds utensils, etc., in an upright orientation as compared to the sideways or flat orientation of the third rack 28. Another dedicated dish holder may be a chopstick basket 150 ( Figure 4), which is generally located in the processing chamber 16 and carried by one of the upper dish rack 32 or the lower dish rack 34. The chopstick basket 150 can be configured to receive chopsticks to be processed, but it should be understood that the chopstick basket 150 can also receive utensils other than chopsticks.

[0027] A dispenser assembly 48 is provided to store treatment chemicals (e.g., detergents, anti-stain agents, etc.) and dispense them into the treatment chamber 16. The dispenser assembly 48 may be mounted on the inner surface of the door assembly 20, as shown, or may be located at other locations within the housing or treatment chamber 16 so that the dispenser assembly 48 is positioned to be accessed by a user to refill the dispenser assembly 48, whether it is necessary to refill the dispenser assembly 48 before each cycle (i.e., for a single-use dispenser) or only periodically (i.e., for a bulk dispenser). The dispenser assembly 48 may dispense one or more types of treatment chemicals. The dispenser assembly 48 may be a single-use dispenser (which holds a single dose of treatment chemicals) or a bulk dispenser (which holds a large amount of treatment chemicals and is suitable for dispensing a certain dose of treatment chemicals from a batch supply during an operating cycle) or a combination of single-use and bulk dispensers. The dispenser assembly 48 may further be configured to hold a plurality of different treatment chemicals. For example, the dispenser assembly 48 may have a plurality of compartments defining different chambers in which treatment chemicals may be held.

[0028] Go to Figure 2 , the spray system 40 is used to spray liquid in the processing chamber 16, and may have a plurality of spray assemblies or sprayers 41, 42, 43, 44, 45, 130, some of which may be dedicated to a specific one of the dish holders, a specific area of ​​the dish holder, a specific type of cleaning, or a specific level of cleaning, etc. The sprayers 41, 42, 43, 44, 45, 130 may be fixed or movable (such as in rotation) relative to the processing chamber 16 or the dish holder. Exemplary sprayers 41, 42, 43, 44, 45, 130 are shown and include an upper spray arm 41, a lower spray arm 42, a third-stage sprayer 43, a deep cleaning sprayer 44, and a spot sprayer 45. The upper spray arm 41 and the lower spray arm 42 may be rotating spray arms, which are respectively located below the upper dish rack 32 and the lower dish rack 34, and rotate around a generally centrally located and vertical axis. The third-stage sprayer 43 is located above the third-stage rack 28. The third stage ejector 43 is shown as being fixed, but may be movable (such as in rotation). In addition to or in lieu of the third stage ejector 43, an ejector 130 may be at least partially located below a portion of the third stage frame 28. The ejector 130 is shown as a fixed tube carried by the third stage frame 28, but may be movable (such as in rotation about a longitudinal axis).

[0029] The deep cleaning jet 44 is a manifold extending along the rear wall of the liner 14 and has a plurality of nozzles 46 with a plurality of holes 47 (which produce a stronger and / or higher pressure jet than the upper jet arm 41), a lower jet arm 42 or a three-stage jet 43. The nozzle 46 can be fixed or movable (such as in rotation). The jet emitted by the deep cleaning jet 44 defines a deep cleaning area, which, as shown, will extend along the rear side of the lower dish rack 34. Therefore, dishes (such as dishes with baked goods) that need deep cleaning can be positioned in the lower dish rack 34 to face the jet 44 for deep cleaning. Although only shown as a unit on the rear wall of the liner 14, the deep cleaning jet 44 may include multiple units and / or extend along multiple parts (including different walls) of the liner 14, and may be arranged above, below or beside any one of the dish holders for which deep cleaning is desired.

[0030] Like the deep cleaning jet, the spot jet 45 can emit an intensified and / or higher pressure jet specifically to a discrete location within one of the dish holders. Although the spot jet 45 is shown below the lower dish rack 34, it can be adjacent to any portion of any dish holder or along any wall of the inner pot that requires special cleaning. In the shown position below the lower dish rack 34, the spot jet can be used independently of the lower spray arm 42 or in combination with the lower spray arm 42. The spot jet 45 can be fixed or movable (such as in rotation).

[0031] These injectors 41, 42, 43, 44, 45, 130 are illustrative examples of suitable injectors and are not meant to be limited to the types of suitable injectors 41, 42, 43, 44, 45, 130. Additionally, it should be understood that not all of the exemplary injectors 41, 42, 43, 44, 45, 130 need to be included in the dishwasher 10, and that fewer than all of the injectors 41, 42, 43, 44, 45, 130 described may be included in a suitable dishwasher 10.

[0032] The recirculation system 50 recirculates the liquid sprayed into the treatment chamber 16 back to the sprayers 41, 42, 43, 44, 45, 130 of the spray system 40 to form a recirculation loop or line, through which the liquid can be repeatedly and / or continuously sprayed onto the dishes in the dish holder. The recirculation system 50 may include a sump 51 and a pump assembly 52. ​​The sump 51 collects the liquid sprayed into the treatment chamber 16 and may be formed by an inclined or recessed portion of the bottom wall of the liner 14. The pump assembly 52 may include one or more pumps (such as a recirculation pump 53). The sump 51 may also be a separate module fixed to the bottom wall and including the pump assembly 52.

[0033] A plurality of supply conduits 54, 55, 56, 57, 58 fluidly couple the ejectors 41, 42, 43, 44, 45, 130 to the recirculation pump 53. A recirculation valve 59 may selectively fluidly couple each of the conduits 54-58 to the recirculation pump 53. Although each ejector 41, 42, 43, 44, 45, 130 is shown as having a corresponding dedicated supply conduit 54-58, one or more subsets of the plurality of ejectors including from the entire group of ejectors 41, 42, 43, 44, 45, 130 may be supplied by the same conduit without requiring a dedicated conduit 54-58 for each ejector 41, 42, 43, 44, 45, 130. For example, a single conduit may supply the upper ejector arm 41 and the third stage ejector 43. Another example is ejector 130 being supplied with liquid by conduit 56, which also supplies the third stage ejector 43.

[0034] Although shown as a single valve, the recirculation valve 59 may be implemented with multiple valves. Additionally, one or more of the conduits 54-58 may be directly coupled to the recirculation pump 53, while one or more of the other conduits 54-58 may be selectively coupled to the recirculation pump 53 with one or more valves. There are essentially an unlimited number of piping schemes to connect the recirculation system 50 to the injection system 40. The piping shown is not limiting.

[0035] Drain system 60 drains liquid from process chamber 16. Drain system 60 includes a drain pump 62 that fluidly couples process chamber 16 to a drain line 64. Drain pump 62 fluidly couples sump 51 to drain line 64 as shown.

[0036] Although separate recirculation 53 and drain pumps 62 are shown, a single pump may be used to perform both the recirculation and drain functions, such as by configuring the single pump to rotate in opposite directions or by providing a suitable valve system. Alternatively, the drain pump 62 may be used to recirculate liquid in conjunction with the recirculation pump 53. When a recirculation pump 53 and a drain pump 62 are used, the drain pump 62 is typically more robust than the recirculation pump 53 because, unlike the recirculation pump 53, the drain pump 62 tends to have to remove solids and dirt from the sump 51, while the recirculation pump 53 tends to recirculate liquid from which solids and dirt have been filtered out, at least to some extent.

[0037] The water supply system 70 is used to supply fresh water to the dishwasher 10 from a water supply source (such as a household water supply) through a household water valve 71. The water supply system 70 includes a water supply unit 72 having a water supply conduit 73 with a siphon 74. Although the water supply conduit 73 can be directly fluidly coupled to the inner tank 14 or any other part of the dishwasher 10, the water supply conduit is shown to be fluidly coupled to a water supply tank 75, which can store the supplied water before use. The water supply tank 75 is fluidly coupled to the sump 51 through a supply line 76, which can include a controllable valve 77 to control when water is released from the water supply tank 75 to the sump 51.

[0038] The water supply tank 75 may be conveniently sized to store a predetermined volume of water, such as that required for the operating cycle phase, which is often referred to as a "charge" of water. Storing water in the water supply tank 75 prior to use is advantageous because the water in the water supply tank 75 may be "treated" in some manner, such as softened or heated prior to use.

[0039] A water softener 78 may be provided with the water supply system 70 to soften fresh water. The water softener 78 is shown as fluidly coupling the water supply conduit 73 to the water supply tank 75 so that the supplied water automatically passes through the water softener 78 on the way to the water supply tank 75. However, the water softener 78 may directly supply water to any other part of the dishwasher 10 other than the water supply tank 75, including directly supplying the inner tank 14. Alternatively, the water softener 78 may be fluidly coupled downstream of the water supply tank 75, such as in series with the supply line 76. In any case where the water softener 78 is fluidly coupled, it may be accomplished with a controllable valve so that the use of the water softener 78 is controllable rather than mandatory.

[0040] A drying system 80 is provided to assist in drying the dishes during the drying phase. The drying system shown includes a condensing assembly 81 having a condenser 82 formed by a curved conduit 83, wherein an inlet is fluidly coupled to an upper portion of the liner 14 and an outlet is fluidly coupled to a lower portion of the liner 14, whereby moisture-saturated air within the liner 14 is drawn from the upper portion of the liner 14, through the curved conduit 83, wherein liquid condenses out of the moisture-saturated air and returns to the processing chamber 16, where it is ultimately evaporated or drained by a drain pump 62. The curved conduit 83 may be operated in an open loop configuration in which air is exhausted to atmosphere or in a closed loop configuration in which air is returned to the processing chamber, or by a combination of operating in one configuration and then in the other.

[0041] To increase the condensation rate, the temperature difference between the outside of the curved conduit 83 and the water-saturated air can be increased by cooling the outside or surrounding air of the curved conduit 83. To this end, an optional cooling box 84 is added to the condensation assembly 81, wherein the curved conduit 83 is located within the cooling box 84. The cooling box 84 is fluidly coupled to at least one of the injection system 40, the recirculation system 50, the drainage system 60, or the water supply system 70 so that liquid can be supplied to the cooling box 84. The liquid provided to the cooling box 84 from any of the systems 40-70 can be selected by the source and / or the stage of the operating cycle so that the temperature of the liquid is lower than the temperature of the water-containing air or even lower than the ambient air.

[0042] As shown, liquid is supplied to a cooling tank 84 through a drain system 60. A valve 85 fluidly connects the drain line 64 to a supply conduit 86 that is fluidly coupled to the cooling tank 84. A return conduit 87 fluidly connects the cooling tank 84 back to the processing chamber 16 via a return valve 79. In this manner, a fluid loop is formed by the drain pump 62, the drain line 64, the valve 85, the supply conduit 86, the cooling tank 84, the return valve 79, and the return conduit 87, through which liquid can be supplied from the processing chamber 16 to the cooling tank 84 and returned to the processing chamber 16. Alternatively, if reuse of the water is not desired, the supply conduit 86 can be fluidly coupled to the drain line 64.

[0043] In order to supply cold water from the domestic water supply to the cooling tank 84 through the domestic water valve 71, the water supply system 70 will first supply cold water to the treatment chamber 16, and then the drainage system 60 will supply the cold water in the treatment chamber 16 to the cooling tank 84. It should be noted that the water supply tank 75 and the cooling tank 84 can be configured so that one tank performs two functions.

[0044] The drying system 80 can use ambient air instead of cold water to cool the outside of the curved duct 83. In this configuration, the blower 88 is connected to the cooling box 84 and can supply ambient air to the interior of the cooling box 84. The cooling box 84 can have a vented top 89 to allow ambient air to pass through, thereby allowing a steady flow of ambient air blown over the curved duct 83.

[0045] Cooling air from the blower 88 can be used instead of or in combination with cold water. When the cooling box 84 is not filled with liquid, the cooling air will be used. Advantageously, the use of cooling air or cooling water or a combination of the two can be selected based on the specific environmental conditions of the site. If the ambient air is lower than the cold water temperature, the ambient air can be used. If the cold water is colder than the ambient air, the cold water can be used. When choosing between cooling air and cooling water, cost-effectiveness can also be considered. The blower 88 can be used to dry the interior of the cooling box 84 after it has been drained. Suitable temperature sensors for cold water and ambient air can be provided, and their temperature signals are sent to the controller 22, which can determine which of the two is colder at any time or stage of the operating cycle.

[0046] A heating system 90 is provided for heating water used in the operating cycle. The heating system 90 includes a heater 92 (such as an immersion heater) located at a location in the treatment chamber 16 where the heater 92 is immersed in the water supplied to the treatment chamber 16, such as in or near the storage tank 51. However, it should also be understood that the heater 92 does not have to be an immersion heater; it can also be an inline heater located in any of the conduits. There can also be more than one heater 92, including immersion heaters and inline heaters. The heater 92 can also heat the air contained in the treatment chamber 16. Alternatively, a separate heating element (not shown) can be provided for heating the air circulating through the treatment chamber 16.

[0047] The heating system 90 may also include a heating loop 93 including a heat exchanger 94, shown as a curved conduit 95 located within the water supply tank 75, with a supply conduit 96 supplying liquid from the treatment chamber 16 to the curved conduit 95, and a return conduit 97 fluidly coupled to the treatment chamber 16. The heating loop 93 is fluidly coupled to the recirculation pump 53, either directly or through a recirculation valve 59, so that liquid heated as part of the operating cycle can be recirculated through the heat exchanger 94 to transfer heat to the charge of fresh water residing in the water supply tank 75. Since most wash stages use liquid heated by the heater 92, this heated liquid can be recirculated through the heating loop 93 to transfer heat to the charge of water in the water supply tank 75, which is typically used in the next stage of the operating cycle.

[0048] A filtration system 100 is provided to filter undissolved solids from the liquid in the processing chamber 16. The filtration system 100 includes a coarse filter 102 and a fine filter 104, which may be a removable basket 106 residing in the sump 51, wherein the coarse filter 102 is a screen 108 surrounding the removable basket 106. Additionally, the recirculation system 50 may include a rotary filter in addition to or in lieu of either or both of the coarse filter 102 and the fine filter 104. Other filter arrangements are contemplated, such as ultrafiltration systems.

[0049] like Figure 3 As schematically shown in FIG. 1 , the controller 22 may be coupled to a heater 92 for heating wash liquid during an operating cycle, a drain pump 62 for draining liquid from the treatment chamber 16, a recirculation pump 53 for recirculating wash liquid during an operating cycle, and a dispenser assembly 48 for selectively dispensing treatment chemicals to the treatment chamber 16. The controller 22 may be provided with a memory 110 and a central processing unit (CPU) 112. The memory 110 may be used to store control software that may be executed by the CPU 112 when completing an operating cycle using the dishwasher 10 and any additional software. For example, the memory 110 may store one or more pre-programmed automatic operating cycles that may be selected by a user and executed by the dishwasher 10. The controller 22 may also receive input from one or more sensors 114. Non-limiting examples of sensors that may be communicatively coupled to controller 22 include ambient air temperature sensors, treatment chamber temperature sensors, water supply temperature sensors, door open / close sensors, and turbidity sensors, to name a few examples, to determine a dirt load associated with a selected set of dishes, such as dishes associated with a particular zone of the treatment chamber. Controller 22 may also be in communication with recirculation valve 59, household water valve 71, controllable valve 77, return valve 79, and valve 85. Optionally, controller 22 may include or communicate with wireless communication device 116.

[0050] Figure 4 A perspective view of a chopstick basket 150 that may be provided with a dishwasher 10 is shown. The chopstick basket 150 may include a base or bottom 152, which may define at least one foot 162. As shown herein, the bottom 152 may define a plurality of feet 162. The feet 162 are configured to allow the chopstick basket 150 to be placed on a surface, such as a countertop, to allow the chopstick basket 150 to be loaded before being placed in the dishwasher 10. Any suitable number of feet 162 may be provided, and their size and spacing may be set to allow the chopstick basket 150 to be stably placed upright on a flat or substantially flat surface.

[0051] The peripheral sidewall 154 may extend upward from the bottom 152 and may at least partially define an interior 180 of the chopstick basket 150. The peripheral sidewall 154 may terminate at an upper edge 156 that may define an open top 182 of the chopstick basket 150 spaced above the bottom 152.

[0052] The chopstick basket 150 may also include a cover 170 that can be removably coupled to the chopstick basket 150 and is configured to selectively cover the open top 182. The cover 170 may include a top surface 178 that may define a plurality of chopstick insertion openings 174. The chopstick insertion openings 174 are configured to receive and hold chopsticks placed in the chopstick basket 150. The chopstick insertion openings 174 may have any suitable shape and size so that the chopsticks can be received in the chopstick insertion openings 174. As a non-limiting example, the chopstick insertion openings 174 may be hexagonal in shape so that the contact points between the chopstick insertion openings 174 and the chopsticks are configured to reduce the formation of water droplets on the chopsticks (particularly on the top of the chopsticks) after processing during the operating cycle of the dishwasher 10. However, it should be understood that any suitable shape can be used for the chopstick insertion openings 174, and other non-limiting examples of the chopstick insertion openings 174 include chopstick insertion openings 174 that are square, polygonal, circular, elliptical, oval, etc. The cover 170 may also include side surfaces 172 depending downwardly from the top surface 178 , which may be used to properly align and center the cover 170 over the upper edge 156 .

[0053] The cover 170 may be configured to move relative to the chopstick basket 150 to selectively cover the open top 182. As a non-limiting example, the cover 170 may slide relative to the chopstick basket 150. The upper edge 156 or the peripheral sidewall 154 may define a cover guide 158, which may be provided as a cover guide channel 158 that is recessed inwardly into the upper edge 156 or the peripheral sidewall 154 toward the interior 180. The cover guide channel 158 may be provided on at least one side of the chopstick basket 150, such as, for example, on two opposite sides of the chopstick basket 150. The cover guide channel 158 may also define at least one stopper 160 corresponding to at least one position of the cover 170 relative to the chopstick basket 150. At least one guide pin 176 may protrude inwardly from the side 172 of the cover 170 to be received in the cover guide channel 158 and guide the sliding movement of the cover 170 relative to the chopstick basket 150. The at least one guide pin 176 may include two guide pins 176 , one of which protrudes from each side 172 of the cover 170 .

[0054] As a non-limiting example, when the cover 170 is in the first covering position, wherein the cover 170 completely covers the open top 182, at least one guide pin 176 may be received and retained in the stopper 160 at one end of the cover guide channel 158. When the cover 170 is in the second at least partially uncovered position, the cover 170 may at least partially expose the open top 182, and at least one guide pin 176 may be received and retained in the stopper 160 at an end of the cover guide channel 159 opposite the first covering position. The configuration of the guide pin 176 in the stopper 160 in the second at least partially uncovered position may further allow the cover 170 to pivot downward from the second at least partially uncovered position to a third storage position, wherein the guide pin 176 is still received in the same stopper 160 and the cover 170 extends along the peripheral side wall 154 of the chopstick basket 150.

[0055] exist Figure 5 , a perspective view of the bottom 152 of the chopstick basket 150 shows that the bottom 152 can define a plurality of openings, which are shown herein as chopstick tip bases 164. The chopstick tip bases 164 can be configured to accommodate the tips of chopsticks placed in the chopstick basket 150, and can be sized and shaped accordingly to accommodate the chopstick tips. The chopstick tip bases 164 can be more specifically defined by an inclined wall 166 provided with the bottom 152 to define each chopstick tip base 164. The positioning of the chopstick tip bases 164 can correspond to the positioning of the chopstick insertion openings 174. Specifically, each chopstick tip base 164 can be aligned with the chopstick insertion openings 174.

[0056] Figure 6 A side view of a chopstick basket 150 coupled to a bracket 200 is shown. The bracket 200 may include at least one coupling mechanism (which is shown herein as a pair of hooks 202) for coupling the bracket 200 to the upper dish rack 32 or the lower dish rack 34. Although the bracket 200 is shown herein as having two hooks 202 for coupling the bracket 200 to the upper dish rack 32 or the lower dish rack 34, it should be understood that any suitable number of hooks 202 may be included. In addition, other coupling mechanisms other than the hooks 202 may be used. Any suitable type of coupling mechanism that can removably or non-removably couple the bracket 200 to the upper dish rack 32 or the lower dish rack 34 may be used, and non-limiting examples of the coupling mechanism include an interference fit coupling mechanism, a snap fit coupling mechanism, or a screw coupling mechanism. In addition, the bracket 200 may include an additional lower hook (not shown) or other lower coupling mechanism for increasing the stability of the bracket 200 against the dish racks 32, 34.

[0057] The bracket 200 may allow the chopstick basket 150 to be coupled to any of the dish racks 32, 34 at any suitable or desired position. For example, the chopstick basket 150 may be coupled to any of the front wall, side wall, or rear wall of any of the dish racks 32, 34. In addition, the bracket 200 may be coupled to any of the dish racks 32, 34 so that the chopstick basket 150 is positioned within the dish racks 32, 34, or positioned on the outer edge of any of the dish racks 32, 34 and not within the interior of any of the dish racks 32, 34.

[0058] The rack 200 includes a rack body 204 that can be maintained in an upright position when the rack 200 is coupled to one of the dish racks 32, 34. The rack body 204 defines a first upright channel 206 and a second non-upright channel 208 that intersects the first upright channel 206. In one example, the first upright channel 206 can be straight and vertical, wherein vertical can mean substantially vertical, and wherein substantially vertical can mean 10° or less from the vertical direction in either direction, and the second non-upright channel 208 can intersect the first upright channel 206 at an orthogonal angle, wherein orthogonal can mean substantially orthogonal, and wherein substantially orthogonal can mean 10° or less from the orthogonal direction in either direction, and further, wherein the second non-upright channel 208 can bend downward as it extends away from the first upright channel 206.

[0059] The chopstick basket 150 may also include at least two coupling pins, which are shown herein as an upper coupling pin 184 and a lower coupling pin 186. The upper coupling pin and the lower coupling pin may be configured to couple the chopstick basket 150 to the bracket 200 by being received in the channels 206, 208 of the bracket 200. The chopstick basket 150 is shown in a first upright position relative to the bracket 200. The chopstick basket 150 may slide downward relative to the bracket 200 so that the lower coupling pin 186 slides in the first upright channel 206 until the lower coupling pin 186 reaches the bottom of the first upright channel 206. When the lower coupling pin 186 is located at the bottom of the first upright channel 206, the upper coupling pin 184 is received in the first upright channel 206 so that the upper coupling pin 184 is positioned at the intersection of the first upright channel 206 and the second non-upright channel 208. The chopstick basket 150 can be resiliently held in the first upright position by the interference fit of the lower coupling pin 186 and the upper coupling pin 184 within the first upright channel 206. When the chopstick basket 150 is in the first upright position, the chopsticks received in the chopstick basket 150 can be held upright for handling during the operation cycle. The upper coupling pin 184 and the lower coupling pin 186 can be shaped and configured such that the removal of the chopstick basket 150 from the bracket 200 can only be accomplished by lifting the chopstick basket 150 (specifically the upper coupling pin 184 and the lower coupling pin 186) upward out of the first upright channel 206.

[0060] Figure 7 The chopstick basket 150 is shown in a second non-upright position coupled to the bracket 200. In the second non-upright position, the chopstick basket 150 can be tilted relative to the first upright channel 206 in either direction away from the vertical direction of the first upright position. When the chopstick basket 150 is tilted, the upper coupling pin 184 moves from the first upright channel 206 to either end of the second non-upright channel 208. The chopstick basket 150 is again elastically retained in the second non-upright position by the interference fit of the upper coupling pin 184 within the second non-upright channel 208. It should also be understood that, instead of or in addition to the interference fit, the chopstick basket 150 can be elastically retained in the second non-upright position by including a stopper (not shown) at either end or both ends of the second non-upright channel 208 into which the upper coupling pin 184 can move or fall.

[0061] When the chopstick basket 150 is in the second non-upright position, the chopsticks received in the chopstick basket 150 can be kept in the non-upright position for handling during the operation cycle. When the chopsticks are kept in the non-upright position for handling, the formation of water drops on the chopsticks (and specifically at the top of the chopsticks or at the contact point between the chopsticks and either or both of the chopstick insertion opening 174 and the chopstick top base 164) can be reduced at the end of the operation cycle compared to handling chopsticks kept in an upright position during handling. In one example, when the chopstick basket 150 is in the second non-upright position, the angle of the chopsticks relative to the vertical direction during handling can be greater than 10° from the vertical direction and less than or equal to 45° from the vertical direction.

[0062] When the chopstick basket 150 is positioned on or near the side wall of any one of the dish racks 32, 34, when the chopstick basket 150 is in the second non-upright position, the chopstick basket 150 can be tilted toward or away from the open face 18 of the inner pot 14. When the chopstick basket 150 is positioned on or near the rear wall or the front wall of any one of the dish racks 32, 34, when the chopstick basket 150 is in the second non-upright position, the chopstick basket 150 can be tilted toward the side wall of the inner pot 14.

[0063] Figure 8A cross-sectional view of the chopstick basket 150 is shown, which shows a cross section of the bottom 152 and wherein the chopstick basket 150 is in a second non-upright position. The chopsticks 400 are received within the interior 180 of the chopstick basket 150, wherein the top ends 404 of the chopsticks 400 are seated within one of the chopstick top end bases 164. While the conventional upright handling position of the chopsticks may result in the formation of water droplets and water spots on the top ends 404 of the chopsticks 400 during or after an operating cycle, the second non-upright position of the chopstick basket 150 allows the chopsticks 400 including the top ends 402 to be held in a non-upright position for handling. In this way, instead of water gathering and remaining on the top ends 402, the water droplets 402 may extend downward along the chopsticks 400, falling from the top ends 402 of the chopsticks 400, including between the top ends 402 and the angled wall 166 or chopstick top end bases 164 due to gravity and the angle of the chopsticks 400 and the chopstick basket 150 in the second non-upright position.

[0064] Fig. 9 Another chopstick basket 250 is shown in accordance with aspects of the present disclosure. The chopstick basket 250 includes many of the same features of the chopstick basket 150, wherein the reference numerals of similar features are increased by 100. The chopstick basket 250 may be identical to the chopstick basket 150, except that the upper edge 256 has a different structure. Rather than including a recessed cover guide channel 158, the chopstick basket 250 may define a cover guide 258, which may be provided as a cover guide rib 258 that protrudes outwardly from the upper edge 256 or the peripheral sidewall 254 and away from the interior 280. The cover guide rib 258 may be provided on at least one side of the chopstick basket 250, such as, for example, on two opposing sides of the chopstick basket 250.

[0065] Likewise, cover 270 includes many of the same features of cover 170, with like features having reference numerals increased by 100. Cover 270 may be identical to cover 170, except that it includes a guide pin 176 to travel within cover guide 158, at least one cover rib 276 ( Fig.10 ) may be configured to engage with the cover guide rib 258 to guide the sliding movement of the cover 270 relative to the chopstick basket 250 and retain the cover 270 on the chopstick basket 250. Although the at least one cover rib 276 is shown herein as a plurality of cover ribs 276, it should be understood that any suitable number of cover ribs 276 may be provided, including only one cover rib 276 that may span any desired length of the side wall 272 of the cover 270.

[0066] The cover 270 is shown in a second at least partially uncovered position, wherein the cover 270 does not completely cover the open top 182, leaving at least a portion of the open top 182 uncovered. When the cover 270 is in the second at least partially uncovered position, chopsticks can still be held by the chopstick insertion opening 274 of the cover 270 in the portion of the interior 280 that is still covered by the cover 270, while taller utensils or utensils that may not fit in the chopstick insertion opening 274 can be placed in the uncovered portion of the interior 280. Utensils that may or may not be chopsticks can also be placed in the chopstick insertion opening 274 of the portion of the cover 270 that does not cover the interior 280, thereby expanding or extending the capacity of the chopstick basket 250 compared to when the cover 270 is in the first covering position. Although the second at least partially uncovered position is shown herein as having an open top 282 that is only partially uncovered by the cover 270, it should be understood that the second at least partially uncovered position may include the open top 282 being completely or almost completely uncovered by the cover 270, such that all or nearly all of the chopstick insertion opening 274 is not covered by the open top 282 or the interior 280.

[0067] Fig.10 The cover 270 is shown in a third storage position. When the cover 270 has been slid to the second at least partially uncovered position, the cover 270 can be pivoted downwardly to the third storage position such that the cover 270 extends or hangs along the peripheral sidewall 254. The cover 270 can include at least one cover hook 288 that can engage with the upper edge 256 to retain the cover 270 in the third storage position. Although the at least one cover hook 288 is shown herein as two separate cover hooks 288, it should be understood that any suitable number of cover hooks 288 can be provided, including a single cover hook 288 that can span up to the entire width of the upper edge 256. In addition, the cover hook 288 can be any suitable coupling mechanism that allows the cover 270 to remain coupled to or hang from the upper edge 256 when the cover 270 is in the third storage position. It should also be understood that the cover 270 can be completely removed from the chopstick basket 250 such that when the cover 270 is in the third storage position, the cover 270 can be lifted to remove the cover hooks 288 from the upper edge 256 .

[0068] Fig.11Another chopstick basket 350 is shown in accordance with aspects of the present disclosure. The chopstick basket 350 includes many of the same features of the chopstick basket 150, wherein the reference numerals of similar features are increased by 200. The chopstick basket 350 may be identical to the chopstick basket 150, except that the upper edge 356 has a different structure. Rather than including a recessed cover guide channel 158, the chopstick basket 350 may define a cover guide 358, which may be provided as a pair of cover guide openings 358 defined in the upper edge 356 or the peripheral sidewall 354. The cover guide openings 358 may be provided in two opposing sides of the chopstick basket 350.

[0069] Likewise, the cover 370 includes many of the same features of the cover 170, with reference numerals for similar features being increased by 200. The cover 370 differs from the cover 170 in that, rather than including the guide pins 176 protruding inwardly from the sidewalls 172, the cover 370 may include guide pins 376 protruding outwardly from the cover 370 and receivable within the cover guide openings 358 of the chopstick basket 350. The cover 370 may include the sidewalls 372, with the guide pins 376 protruding outwardly from the sidewalls 372. In another example, the cover 370 need not include the sidewalls 372, and the guide pins 376 may instead protrude outwardly from the top surface 378.

[0070] When the guide pin 376 is received in the cover guide opening 358, the cover 370 can be configured to pivotally move relative to the chopstick basket 350 about the guide pin 376. The cover 370 can have a full range of pivotal movement relative to the chopstick basket 350, so that the cover 370 can be in a first covering position that completely covers the open top 382, ​​in a second at least partially uncovered position, wherein the cover 370 is at least partially pivoted away from the chopstick basket 350 to at least partially expose the open top 382, ​​or in a third storage position, wherein the cover 370 can be rotated downward from the second at least partially uncovered position to extend along the peripheral side wall 354.

[0071] Although a plurality of chopstick baskets 150, 250, 350 and a plurality of covers 170, 270, 370 have been described herein, it should be understood that any one of the chopstick baskets 150, 250, 350 and any one of the covers 170, 270, 370 may be provided in conjunction with the stand 200 and may allow any one of the chopstick baskets 150, 250, 350 to be movable between a first upright position and a second non-upright position. In addition, although the covers 170, 270, 370 have been described herein as being slidable or pivotable relative to the chopstick baskets 150, 250, 350, it should be understood that any suitable cover may be provided in conjunction with any of the chopstick baskets 150, 250, 350 and the stand 200, non-limiting examples of which include a cover that is hingedly attached, a cover that is attached by an interference fit, or a cover that is snap-fitted into or onto the chopstick baskets 150, 250, 350.

[0072] Aspects described herein can be used to provide a chopstick basket for a dishwasher that is configured to improve the handling performance of chopsticks. Handling chopsticks in an upright position can result in water droplet formation on the chopsticks during and after the operating cycle. By placing the chopstick basket in a second, non-upright position, the chopsticks can be handled while being held at an angle, thereby reducing water droplet formation on the top of the chopsticks and at the point where the chopsticks contact the chopstick insertion port on the chopstick basket cover. Having a chopstick basket that can occupy an upright handling position or a non-upright handling position also provides users with increased choices and flexibility. In addition, providing a non-upright handling position can also allow for accommodating taller sizes than standard chopsticks or utensils.

[0073] In addition, aspects described herein provide chopstick baskets with various cover configurations, which can be used with or without a bracket, thereby allowing movement between a first upright position and a second non-upright position. In one example, when the cover is in at least a partially uncovered position, having a slidable cover allows additional processing space for chopsticks or utensils. The cover can also slide from a covered position to at least a partially uncovered position, and then can be pivoted downward to a third storage position to allow the user to have additional flexibility. The cover can completely cover the chopstick basket, partially cover the chopstick basket, or hang along the sidewall of the chopstick basket, but still be held or coupled to the chopstick basket by the chopstick basket in any position. This can ensure that even when the cover is not used with the chopstick basket, it can also be easily and conveniently stored, and will not be as easily lost as a fully removable cover without a storage position coupled to the chopstick basket.

[0074] It should also be understood that various changes and / or modifications may be made without departing from the spirit of the present disclosure. As a non-limiting example, although the present disclosure is described for use with a door assembly that can pivot about a horizontal axis, it should be appreciated that the door assembly can take on a variety of configurations, including a door assembly that can pivot about a vertical axis and / or a door assembly for a drawer dishwasher.

[0075] To the extent not described, different features and structures of various aspects can be used in combination with each other as needed. The feature not shown in all aspects is not meant to be interpreted as not being able to be, but is done for the sake of brevity of description. Therefore, various features of different aspects can be mixed and matched as needed to form new aspects, whether or not the new aspects are explicitly described. The present disclosure covers combinations or permutations of the features described herein.

[0076] This written description uses examples to disclose various aspects of the disclosure, including the best mode, and also enables any person skilled in the art to practice various aspects of the disclosure, including making and using any device or system and performing any combined method. Although various aspects of the disclosure have been described in detail in conjunction with certain specific details of the present invention, it should be understood that this is by way of illustration and not limitation. Reasonable changes and modifications are possible within the scope of the foregoing disclosure and the drawings without departing from the spirit of the disclosure as defined by the appended claims.
