equipped rack assemblies 144 , 148 . each of the upper and lower racks 144 , 148 is fabricated from lattice structures that include a plurality of elongated members 142 . each rack 144 , 148 is adapted for movement between an extended loading position ( not shown ) in which the rack is substantially positioned outside wash chamber 128 , and a retracted position ( shown in fig2 ) in which the rack is located inside wash chamber 128 . a silverware basket 130 is removably mounted to upper rack assembly 144 . however , silverware basket 130 may also be selectively attached to other portions of dishwasher appliance 100 , e . g ., lower rack 148 or door assembly 118 . silverware rack 130 is configured for receipt of silverware , utensils , and the like , that are too small to be accommodated by the upper and lower racks 144 , 148 . the dishwasher appliance 100 further includes a lower spray assembly 152 that is mounted within a lower region of the wash chamber 128 and above a sump portion so as to be in relatively close proximity to the lower rack 148 . a mid - level spray assembly 146 is located in an upper region of the wash chamber 128 and may be located in close proximity to upper rack 144 . additionally , an upper spray assembly ( not shown ) may be located above upper rack 144 . the lower and mid - level spray assemblies 152 , 146 are fed by a fluid circulation assembly ( not shown ) for circulating water and dishwasher fluid in wash chamber 128 . at least part of the fluid circulation assembly may be located in machinery compartment 154 located below the sump portion of tub 132 as generally recognized in the art . each spray assembly includes an arrangement of discharge ports or orifices for directing washing liquid onto dishes or other articles located in the upper and lower racks 144 , 148 and silverware basket 130 . the lower and mid - level spray assemblies 152 , 146 may be rotatably mounted in wash chamber 128 . accordingly , the arrangement of the discharge ports may provide a rotational force by virtue of washing fluid flowing through the discharge ports . the resultant rotation of the spray assemblies 146 , 152 can provide coverage of dishes and other dishwasher contents with a washing spray . dishwashing appliance 100 includes a sound abating device 170 that is connected to body 134 along opposing sides 166 , 168 and top side 164 . for this exemplary embodiment , sound abating device 170 is constructed from a plurality of resilient strips 172 , 174 , 176 , 178 , and 180 — the construction of which will be further described herein . while sound abating device 170 could be formed as one continuous strip , for the exemplary embodiment shown , strips 172 , 174 , 176 , 178 , and 180 contact each other to form a substantially continuous seal for sound abatement as will be further described . thus , as shown in fig1 , for this exemplary embodiment sound abating device 170 extends in a substantially continuous manner around body 134 and along sides 164 , 166 , and 168 . in addition , sound abating device 170 extends from body 134 into contact with adjacent cabinetry 102 . more particularly , sound abating device 170 extends into contact with the bottom surface 106 of counter - top 104 along top side 164 . along opposing sides 166 and 168 , device 170 extends into contact with inside cabinetry surfaces 103 defining opening 112 . along opposing sides 166 and 168 , sound abating device 170 extends to the top surface 110 of support or floor 108 . sound abating device 170 assists in attenuating the passage of sound generated by dishwashing appliance 100 and transmitted into spaces 212 ( fig5 and 7 ) between appliance 100 and cabinetry 102 by sealing off the same when appliance 100 is installed in opening 112 . an exemplary embodiment of sound abating device 170 is set forth in fig4 and shown installed on appliance 100 in fig5 . fig4 provides an end view and fig5 provides a cross - sectional view that could be taken anywhere along the length of device 170 . in order to attenuate the passage of sound from appliance 100 that is transmitted into the space 212 between appliance 100 and cabinetry 102 , device 170 includes a baffle portion 184 as shown in the exemplary embodiment set forth in fig4 and 5 . baffle portion 184 defines at least one chamber 186 extending longitudinally along sound abating device 170 . chamber 186 is defined by a first leg 202 and a second leg 204 , each of which is attached to a connecting portion 182 along a seam 200 . first leg 202 and 204 are also connected along a distal end 212 of device 170 . each leg 202 , extends away from connecting portion 182 towards cabinetry 102 and into contact with cabinetry surface 103 when dishwashing appliance 100 is installed . as shown in fig5 , by moving dishwashing appliance 100 into the opening 112 of cabinetry 102 , sound abating device 170 is folded or bent along seam 200 from an original position ( shown in fig5 in phantom lines ) to an installed position ( shown in fig5 in solid lines ). a notch 208 on the inside surface of first leg 202 assists in controlling deformation of chamber 186 ; multiple notches on legs 202 , 204 , or both , may be used . even though baffle portion 184 may be slightly compressed in the installed position , chamber 186 is still present as shown . an optional extension 210 also extends from seam 200 chamber 186 , along with legs 202 and 204 , attenuates the propagation of sound through sound abating device 170 . as such , sound abating device 170 reduces or blocks sound created by appliance 100 that is transmitted into the space 212 between appliance 100 and cabinetry 102 and that would otherwise escape into an associated room or space . more particularly , it is believed that sounds generated by different sources in a dishwasher such as appliance 100 are dominated by low frequencies . low frequency sound is more difficult to attenuate without any barrier . with its single or multi - layer construction ( as created by e . g ., one or more chambers ), the sound abating device of the present invention can be fine - tuned for low frequency sound sources to achieve a higher sound transmission loss . the single or multiple layers of the sound abating device ( such as device 170 ) can be constructed of rubber materials , polymeric materials , poroelastic materials , and / or air layers that result in significant impedance mismatch at their interfaces , causing a higher proportion of sound power to be reflected back . this technical advantage allows for less sound power to reach the consumer . the present invention also provides a commercial advantage over certain conventional devices in that it can be implemented with a small incremental cost through addition to existing parts with a relatively highly significant sound performance gain for the entire dishwasher . sound abating device 170 also includes a connecting portion 182 used for attachment to the body 134 of appliance 100 . in this exemplary embodiment , connecting portion 182 defines a slot 192 for the receipt of a flange 190 that extends from body 134 along opposing sides 166 , 168 , and top side 164 . slot 192 extends longitudinally along connecting portion 182 . a plurality of fingers 196 extend into slot 192 are configured for securing connecting portion 182 to flange 190 . fig6 and 7 illustrate another exemplary embodiment of the sound abating device 170 similar in certain respects to the embodiment of fig4 and 5 . however , for the embodiment of fig6 and 7 , sound abating device 170 includes a plurality of chambers 186 and 188 . although only two chambers 186 , 188 are shown , in other embodiments of the invention still more chambers may be used . also , for this exemplary embodiment , connecting portion 182 lacks a slot . instead , connecting portion 182 is attached by e . g ., glue or mechanical fasteners to flange 190 . thus , multiple different techniques and configurations of connecting portion 182 may be used with the present invention . in one aspect of the invention , materials having different durometers are used in the construction of sound abating device 170 . for example , connecting portion 182 has a durometer greater than the durometer of fingers 196 . thus , fingers 196 have a certain flexibility that aids in attachment to flange 190 . similarly , connecting portion 182 has a durometer greater than baffle portion 182 to allow baffle portion to be flexible and bend into space 212 while connection portion has sufficient rigidity to anchor device 170 . a variety of materials may be used in the construction of device 170 . for example , one or more extrusion grade poly - vinyl chlorides ( pvcs ), silicone rubbers , and / or other materials may be used in construction . 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 .
a dishwashing appliance is provided having one or more sound abatement features for blocking sound transmission emanating from the appliance during operation . spaces or gaps present between the dishwashing appliance and the cabinetry in which it is installed can be blocked by features having one or more chambers that attenuate the transmission of sound therefrom . such sound abatement features can be readily incorporated into the design of a dishwashing appliance and provide a relatively inexpensive alternative to conventional designs .
