Description
- The present subject matter relates generally to dishwashing appliances, and more particularly to doors and dispenser assemblies mounted thereon to supply a wash additive to a dishwashing appliance.
- Dishwashers or dishwashing appliances generally include a tub that defines a wash compartment. Rack assemblies can be mounted within the wash compartment of the tub for receipt of articles for washing. In a typically known dishwashing appliance, spray assemblies within the wash compartment can apply or direct wash fluid towards articles disposed within the rack assemblies in order to clean such articles. Multiple spray assemblies can be provided including, for example, a lower spray arm assembly mounted to the tub at a bottom of the wash compartment, a mid-level spray arm assembly mounted to one of the rack assemblies, or an upper spray assembly mounted to the tub at a top of the wash compartment.
- In order to facilitate cleaning of articles in a dishwashing appliance, cleaning agents or wash additives are used. During operation of the dishwashing appliance, the wash additives generally mix with water in the wash compartment to form a fluid that is used to clean articles within the wash compartment. Wash additives include, for example, detergents and rinse agents. In some cases, liquid wash additives are used.
- For some existing appliances, wash additives are stored in one or more reservoirs defined in the doors of dishwashing appliances and are dispensed from these reservoirs during operation of the dishwashing appliance. In many of these existing appliances, the reservoir(s) are generally provided as separable elements that can be mounted to the door by conventional brackets and mechanical fasteners. As an example, multiple screws can be inserted through a bracket surrounding the reservoir and into a portion of the door. Alternatively, a set of bracket tabs may be integrally formed in a stainless steel panel of the door that encloses the wash compartment.
- These existing designs come with various drawbacks. For instance, in the case of a bracket attached to the door via multiple screws, it can be difficult and expensive to properly assemble the appliance. Specifically, the screws must be carefully aligned to ensure a proper seal. Even when done correctly, this is time-consuming and requires purchase of large numbers of screws, which generally adds to the expense of the appliance. In the case of an integral bracket, it can be difficult and expensive to require stainless steel across the entire panel of the door. Moreover, it can be difficult to ensure a proper seal is maintained between the reservoir and door to prevent water from leaking into the door from the wash compartment.

FIGS. 3 and 4 , perspective views are provided for portions of adoor 108 having aninner panel 196 and anouter panel 198, such as that for dishwasher 100 (FIGS. 1 and 2 ). Specifically,FIG. 3 provides a perspective view ofdoor 108, such that afront surface 210 ofinner panel 196 is visible.FIG. 4 provides a perspective view of an interior portion of the door 108 (e.g., betweeninner panel 196 and outer panel 198), such that aback surface 212 ofinner panel 196 is visible. It is understood that as described below, references to the vertical, lateral, and transverse directions (e.g., defined by door 108) are made with respect to thedoor 108 being in the closed position (e.g., as illustrated inFIG. 2 ). Thus,door 108 generally extends along the vertical direction V between atop end 107 and abottom end 108, between the lateral direction L between afirst end 214 and asecond end 216, and along the transverse direction T between an inner side 218 (e.g., at front surface 210) and an outer side 220 (e.g., at outer panel 198). Moreover,inner panel 196 generally faceswash chamber 106 whileouter panel 198 faces the ambient environment. -
Inner panel 196 andouter panel 198 may be formed of different materials or, alternatively, the same material. In certain embodiments,inner panel 196 is or includes a polymer material (i.e., is formed from a polymer material), such those including poly-propylene. In additional or alternative embodiments,outer panel 198 is or includes a metal or glass material (i.e., is formed from a metal or glass material). - In some embodiments, a dispensing
assembly 224 is provided at or oninner panel 196 ofdoor 108 to receive and dispense the wash fluid (e.g., liquid, powder, or pod cleaning agent) to thewash chamber 106. In particular, dispensingassembly 224 may be attached to theinner panel 196 of thedoor 108. A stampedhole 222 defined through theinner panel 196 along an aperture axis A (e.g., parallel to the transverse direction T) may receive a portion of dispensingassembly 224. Thus, dispensingassembly 224 may be fixed to thedoor 108 and thereby move with the door 108 (e.g., as it is moved between the open and closed positions). Generally, attachment of dispensingassembly 224 todoor 108 will be described in greater detail below - Turning now generally to
FIGS. 3 through 5 and 11 ,FIG. 5 provides a magnified view of the interior portion ofdoor 108 and dispensingassembly 224 whileFIG. 11 provides a perspective view of a retainingcup 226 that defines anadditive compartment 228. As shown, dispensingassembly 224 includes a retainingcup 226 defining at least oneadditive compartment 228 to receive or hold a volume of wash additive therein. Retainingcup 226 includes one or more cup walls (e.g., sidewalls 232 and base wall 234) that, when mounted todoor 108, the cup walls generally extend rearward throughinner panel 196 and within the interior portion ofdoor 108 partially enclose theadditive compartment 228. Specifically, an interior surface ofsidewalls 232 definesadditive compartment 228. A front opening may be defined by the one or more sidewalls 232 opposite of thebase wall 234. Optionally, a separate dispensing outlet (not shown) may be provided throughsidewalls 232 orbase wall 234 for the selective release of wash additive or cleaning agent to thewash tub 106. As will be further described below, anexterior surface 236 ofsidewalls 232 defines one ormore reliefs 240 outside of the additive compartment 228 (e.g., within the interior portion of door 108). Eachrelief 240 generally faces towards the front opening. Optionally, one or more of thereliefs 240 may include multiple teeth arranged in an ascending step sequence in the transverse direction T along a path extending away from the front opening. - As shown, retaining
cup 226 is formed as an open box in exemplary embodiments. Nonetheless, any other suitable shape for receiving and containing liquids, such as a cleaning agent, may be provided in alternative embodiments. - In certain embodiments, a
front cover 242 is provided to selectively cover or closeadditive compartment 228. For instance, thefront cover 242 may be placed over the front opening, enclosingadditive compartment 228 and restricting access thereto. Moreover,front cover 242 may be joined to retainingcup 226 forward from stampedhole 222. Thus, when the door 108 (FIG. 2 ) is in the closed position, thefront cover 242 is positioned betweenadditive compartment 228 and washchamber 106. As shown, aradial lip 244 offront cover 242 is larger than the perimeter edge 258 defining stampedhole 222. When assembled, theradial lip 244 may thus be positioned radially outward from the perimeter edge 258. During use, such as when adding wash additive toadditive compartment 228, a portion offront cover 242 may be moved apart (e.g., pivoted away) from the front opening or otherwise adjusted such that access toadditive compartment 228 is permitted. - Turning now to
FIGS. 5 and 6 , as well asFIGS. 9 and 10 , various views are provided to illustrate adiscrete bracket 250 of dispensingassembly 224.FIGS. 5 and 6 provide perspective views ofdiscrete bracket 250 mounted to the rest of dispensingassembly 224 whileFIGS. 9 and 10 provide perspective views ofdiscrete bracket 250 in isolation. - Within the door 108 (i.e., within the interior portion), a
discrete bracket 250 can selectively secureadditive dispensing assembly 224 toinner panel 196. Generally,discrete bracket 250 is separate frominner panel 196 and retainingcup 226 and, thus, can be moved relative to the same prior to assembly. As shown,discrete bracket 250 includes anannular base 252 and one or moreresilient wings 254.Annular base 252 may have a continuous perimeter that defines a central hole that is larger than the lateral and vertical dimensions of retainingcup 226. When mounted,annular base 252 can be disposed about theexterior surface 236. Thus, retainingcup 226 can be received through the central hole ofannular base 252. - The
resilient wings 254 may extend fromannular base 252. In particular, theresilient wings 254 may extend from the inner radial perimeter of theannular base 252 away from theinner panel 196. Additionally or alternatively, theresilient wings 254 may be biased towards the central hole such that a non-parallel or non-perpendicular angle is defined by eachresilient wing 254 relative to the transverse direction T or aperture axis A. If multipleresilient wings 254 are provided, eachresilient wing 254 may be spaced apart from the others (e.g., circumferentially) about the central hole ofannular base 252. In some embodiments,discrete bracket 250 is formed as an integral or unitary (e.g., monolithic) member. For instance,discrete bracket 250 may be stamped from a single piece of sheet metal. Thus,discrete bracket 250 may be a metal material, such as stainless steel. - When assembled, the
resilient wings 254 may contact or engage thereliefs 240 ofexterior surface 236. In particular, the elastic character of theresilient wings 254 may bias theresilient wings 254 radially inwards against theexterior surface 236 while an axial tip of one or moreresilient wings 254 pushes axially against acorresponding relief 240. A planar rim ofannular base 252 may be held in contact (e.g., direct contact) againstback surface 212. The counteracting axial force, for instance, ofradial lip 244 against thefront surface 210 ofinner panel 196 may serve to holddiscrete bracket 250 in place (e.g., without requiring any adhesive or mechanical fasteners). Specifically,discrete bracket 250 may be held within thedoor 108 between aback surface 212 of thedoor 108 and therelief 240 of the retainingcup 226. As shown, eachresilient wing 254 may correspond to adiscrete relief 240 defined byexterior surface 236. - Although exemplary embodiments may hold
discrete bracket 250 about the stampedhole 222 without the need of any adhesive or separate mechanical fasteners, a portion ofinner panel 196 may radially bound a portion ofdiscrete bracket 250. For instance, as shown, a portion of theback surface 212 ofinner panel 196 may define apocket 256 extending (e.g., circumferentially) about a portion ofdiscrete bracket 250. In some such embodiments,discrete bracket 250 is held withinpocket 256. Thus,pocket 256 may limit at least a portion of radial movement (e.g., in the lateral direction L or vertical direction V) ofdiscrete bracket 250 along theback surface 212 ofinner panel 196. - Turning especially to
FIGS. 5 through 8 ,FIGS. 7 and 8 provide cross-section views of dispensingassembly 224 that illustrate engagement between dispensingassembly 224 andinner panel 196. As shown, aflat compression gasket 260 is provided between at least a portion ofinner panel 196 andradial lip 244.Flat compression gasket 260 may be formed from a material configured to compress predominately in a primary direction (e.g., axially). For instance,flat compression gasket 260 may be (e.g., formed from) a closed-cell foam material. - Generally,
flat compression gasket 260 has a continuous perimeter that defines a central hole. Specifically,flat compression gasket 260 defines aminor edge 262 and a largermajor edge 264 about the central hole, and thus has a generally toroidal shape (e.g., defined according to a rectangular cross section). When assembled,flat compression gasket 260 is disposed about retainingcup 226. In particular,minor edge 262 is positioned proximal toexterior surface 236 whilemajor edge 264 is positioned distal to (e.g., further radially outward from)exterior surface 236 relative to the aperture axis A. Thus, retainingcup 226 can also be received through the central hole offlat compression gasket 260. - Generally, the
major edge 264 offlat compression gasket 260 is larger than the perimeter edge 258 defining stampedhole 222. Additionally or alternatively,major edge 264 may be larger than the innermost edge ofannular base 252. Thus, when assembled,major edge 264 may be disposed radially outward from the perimeter edge 258 of stampedhole 222 and the innermost edge ofannular base 252. As shown inFIG. 7 , in some embodiments, theminor edge 262 offlat compression gasket 260 is larger than the perimeter edge 258 defining stampedhole 222. Thus, when assembled,minor edge 262 may be disposed radially outward from the perimeter edge 258 of stampedhole 222. As shown inFIG. 8 , in alternative embodiments, theminor edge 262 offlat compression gasket 260 is smaller than the perimeter edge 258 defining stampedhole 222. Thus, when assembled,minor edge 262 may be disposed radially inward from the perimeter edge 258 of stampedhole 222. - Between the
minor edge 262 andmajor edge 264,flat compression gasket 260 may define a pair of flat surfaces. Specifically,flat compression gasket 260 may define aforward surface 266 and arearward surface 268.Forward surface 266 andrearward surface 268 may be parallel to each other (e.g., perpendicular to the aperture axis A or transverse direction T). Moreover,radial lip 244 may define a complementary rear-facing surface to contactforward surface 266 while thefront surface 210inner panel 196 defines a flat surface (e.g., planar and unrounded about stamped hole 222) complementary torearward surface 268. - During assembly, the retaining
cup 226 may be pushed through the stampedhole 222 andflat compression gasket 260 from thefront surface 210 while thediscrete bracket 250 is pushed in the opposite direction towards theback surface 212 ofinner panel 196. A portion of the exterior surface 236 (e.g., expanding ramp portion) rearward of thereliefs 240 may deflect theresilient wings 254 radially outward before theresilient wings 254 are able to snap back and into engagement with thereliefs 240. The counteracting forces ofdiscrete bracket 250 andradial lip 244 may compressflat compression gasket 260 axially. Advantageously,flat compression gasket 260 may seal the stampedhole 222 both axially and radially (e.g., without requiring any gasket or seal segment that extends through stamped hole 222). - This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they include structural elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal languages of the claims.
