DETAILED DESCRIPTION
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
Referring now to the drawings, FIGS. 1-10 illustrate an exemplary embodiment of a rack system 100 suitable for installation to a kitchenware washing assembly 102. The rack system 100 may be used to hold kitchenware within a tank 104 of the washing assembly 102 during washing operation. As will be described in more detail hereinafter, the rack system 100 may be adjusted within the tank 104 of the washing assembly 102, for example, to accommodate different sizes, types, etc. of kitchenware. In the illustrated embodiment, the kitchenware includes sheet pans 106 and 108. While the illustrated sheet pans 106 and 108 are differently sized, sheet pans 106 and 108 can be similarly sized within the scope of the present disclosure. In addition, in other exemplary embodiments, rack systems can accommodate sheet pans having more than two different sizes. It is to be understood that the present disclosure should not be limited to rack systems used to hold/accommodate sheet pans. For example, rack systems can accommodate kitchenware including trays, dishes, sheet ware for displaying, for example, large volumes of food, pots, silverware, dishware, food service ware and equipment, food trays, grease filters, gratings, other kitchen items that may require cleaning, etc. within the scope of the present disclosure.
As shown in FIGS. 1 and 2, the washing assembly 102 generally includes the tank 104 for holding fluid (e.g., water, cleaning fluid, etc.) for washing the kitchenware, an inlet 110 for removing fluid from the tank 104, and outlets 112 (only one is visible) for discharging fluid into the tank 104. Intake plates may be positioned over the inlet 110 within the scope of the present disclosure. Discharge plates may be positioned over one or more of the outlets 112 within the scope of the present disclosure. One or more pumps (not shown) may be located, for example, under the tank 104 for circulating the fluid in the tank 104 from the inlet 110 to the outlets 112 for use in washing the kitchenware. Fluid conduits 114 may couple the one or more pumps, in fluid communication, between the inlet 110 and the outlets 112. The washing assembly 102 may include a number of inlets and outlets other than disclosed herein within the scope of the present disclosure. And washing assemblies configured (e.g., sized, shaped, constructed, etc.) differently than disclosed herein may be used.
The illustrated washing assembly tank 104 is generally rectangular in shape and generally includes a forward wall 116, an opposing rearward wall 118, a bottom wall 120 (FIG. 2), and two side walls 122 and 124. The walls 116, 118, 120, 122, and 124 are arranged to hold the fluid in the tank 104 for washing operation. Because it is desirable to have the fluid discharge into the tank 104 from the outlets 112 in a generally downwardly angled direction (e.g., to help avoid splashing fluid out of the tank 104, etc.), the side walls 122 and 124 can include portions that are angled generally downwardly. The outlets 112 can be located on these generally downwardly angled portions of the side walls 122 and 124 such that the fluid discharging into the tank 104 from the outlets 112 is directed in the generally downwardly angled direction. Alternative embodiments, however, can include tanks formed with more or less than four walls (e.g., more or less than a forward wall, a rearward wall, and two side walls, etc.) and/or tanks formed in any other suitable configuration including, for example, cup-shaped, cylindrical, cubical, triangular, trapezoidal, circular, ovular, prismatic, a configuration having four walls generally perpendicular to the bottom, etc.
With reference now to FIGS. 3-6, the illustrated rack system 100 generally includes first and second mounting fixtures 126 and 128 connectable to the tank 104 of the washing assembly 102, and three racks 130, 132, and 134 connectable to the mounting fixtures 126 and 128. A hanging basket 135 (FIGS. 1 and 3) is also connectable to the second mounting fixture 128. In the illustrated embodiment, the racks 130, 132, and 134 may be understood to be connectable to the washing assembly tank 104 via the mounting fixtures 126 and 128. And the hanging basket 135 may be understood to be connectable to the washing assembly tank 104 via the second mounting fixture 128.
The mounting fixtures 126 and 128 each include a base plate 136 and a flange 138. And the flange 138 extends generally away from the base plate 136 in a generally forwardly direction. The flange 138 of each mounting fixture 126 and 128 can be integrally, monolithically, etc. formed as one piece of material with the base plate 136. Openings 140 are formed in the flange 138 of each mounting fixture 126 and 128, and the racks 130, 132, and 134 can connect to the mounting fixtures 126 and 128 at the openings 140. The openings 140 allow the racks 130, 132, and 134 to be connected to, disconnected from, adjusted (e.g., moved, slid, etc.) relative to, reconnected to, etc. the mounting fixtures 126 and 128 as desired. Openings 141 are formed generally above the openings 140 in each mounting fixture 126 and 128, and generally between the base plate 136 and the flange 138 of each mounting fixture 126 and 128. The hanging basket 135 can connect to the second mounting fixture 128 at the openings 141 and hang at least partly within the washing assembly tank 104 for washing, for example, kitchenware (e.g., utensils, etc.). The openings 141 allow the hanging basket 135 to be connected to, disconnected from, adjusted (e.g., moved, slid, etc.) relative to, reconnected to, etc. the mounting fixture 128 as desired. The hanging basket 135 could be connected to the first mounting fixture 126 within the scope of the present disclosure.
In other exemplary embodiments, rack systems may include more than or less than two mounting fixtures and/or more than or less than three racks. In addition, exemplary embodiments may include more than or less than one hanging basket. For example, in one exemplary embodiment, a rack assembly may include four racks. In still other exemplary embodiments, rack systems may include mounting fixtures configured (e.g., sized, shaped, constructed) differently than disclosed herein but still capable of supporting and/or holding a rack and/or a hanging basket; and/or allowing connection of a rack and/or a hanging basket thereto; and/or allowing adjustment of a rack and/or a hanging basket relative thereto. In further exemplary embodiments, hanging fixtures other than hanging baskets may be connectable to washing assembly tanks, for example, for holding items within the tank for washing. In still other exemplary embodiments, hanging baskets may be configured (e.g., sized, shaped, constructed, etc.) differently than illustrated herein.
With additional reference to FIGS. 7-10, rack 130 of the rack system 100 will be described with it to be understood that a description of racks 132 and 134 is substantially the same. The rack 130 includes a frame 142 comprising multiple spaced apart support sections 144 (broadly, supports) configured (e.g., sized, shaped, constructed, etc.) to hold kitchenware (e.g., the sheet pans 106 and 108, etc.) in the rack 130 (e.g., FIGS. 3 and 4, etc.). Each support section 144 has a generally rectangular shape with rounded corners. A longitudinal support member 146 extends generally between upper and lower sides 148 and 150 of each support section 144 to help provide rigidity, strength, stability, etc. thereto. And connection members 152, 154, and 156 connect the multiple support sections 144 of the frame 142 together. Connection members 152 and 154 extend through each support section 144 and connect to the longitudinal support members 146 of each support section 144; and connection member 156 extends generally under each support section 144 and connects to the lower side 150 of each support section 144. Together, the connection members 152, 154, and 156 can help securely hold the support sections 144 in a generally aligned orientation and may provide rigidity, strength, stability, etc. to the frame 142 of the rack 130.
The illustrated rack 130 also includes a forward mount 158 and a rearward mount 160 that connect to a respective forward support section 144 and rearward support section 144 of the rack frame 142. The mounts 158 and 160 can be used to connect the rack 130 to the forward and rearward walls 116 and 118 of the washing assembly tank 104 (e.g., via the openings 140 in the mounting fixtures 126 and 128, etc.). The forward mount 158 includes a pair of pins 162 that connect (e.g., by a weld connection, a solder connection, an adhesive connection, a mechanical fastener connection, etc.) to longitudinal sides 164 and 166 of the forward support section 144, generally toward the upper side 148 of the support section 144. The two pins 162 are each configured (sized, shaped, constructed, etc.) to fit in one of the openings 140 of the mounting fixture 126 connected to the forward wall 116 of the washing assembly tank 104 (FIGS. 1 and 3). A transverse support member 168 extends between the pins 162 to help provide rigidity, strength, stability, etc. thereto. The rearward mount 160 includes a pair of generally U-shaped members 170 that connect (e.g., by a weld connection, a solder connection, an adhesive connection, a mechanical fastener connection, etc.) to longitudinal sides 164 and 166 of the rearward support section 144. The U-shaped members 170 also each include a pin 172 at a free end thereof, each configured (sized, shaped, constructed, etc.) to fit in one of the openings 140 of the mounting fixture 128 connected to the rearward wall 118 of the washing assembly tank 104 (FIGS. 1 and 3). Transverse support members 174 extend between the U-shaped members 170 to help provide rigidity, strength, stability, etc. thereto. The forward and/or rearward mounts 158 and/or 160 can each include more than or less than two pins within the scope of the present disclosure.
The illustrated rack 130 includes nine support sections 144 connected together to form the frame 142. The nine support sections 144 are each similarly oriented at an angle A1 of about fifty-five degrees (FIG. 8). This angled orientation can help, for example, the sheet pans 106 and 108 received by the rack system 100 fit generally completely within the tank 104 of the washing assembly 102 (and thus can help clean the entire sheet pans 106 and 108 without having to adjust them during cleaning operation). Each support section 144 is spaced laterally apart from an adjacent support section 144 by a distance of about 1.8 inches (about 4.5 centimeters) to define a gap between the support sections 144 for receiving the sheet pans 106 and 108 into the rack 130. This spacing allows the sheet pans 106 and 108 to fit between adjacent support sections 144, while also helping restrict the sheet pans 106 and 108 from undesired movement during washing operation (e.g., movement out of the rack 130, etc.). Also in the illustrated rack 130, the longitudinal sides 164 and 166 of each support section 144 may include a length dimension of about 17.9 inches (45.5 centimeters), and upper and lower sides 148 and 150 of each support section 144 may include a length dimension of about 3.0 inches (7.6 centimeters). Further, an overall length dimension of the rack 130 may be about 27.3 inches (69.3 centimeters), and an overall height dimension of the rack 130 may be about 14.3 inches (36.3 centimeters). In other exemplary embodiments, rack systems may include racks having more than or less than nine support sections. In still other exemplary embodiments, rack systems may include racks and/or rack support sections with dimensions, angular orientations, etc. different from those disclosed herein.
Components of the rack 130, including the frame 142, the forward mount 158, the rearward mount 160, etc., and/or components of the hanging basket 135 may be formed from metal rods (e.g., steel rods, aluminum rods, etc.) which can be bent, shaped, etc. to the desired form described and illustrated herein. In other exemplary embodiments, components of the rack 130 and/or components of the hanging basket 135 may be formed from materials, including, for example, plastics, nylons, polymers, metals, combinations thereof, etc., and may be formed by processes other than bending (e.g., mold processes, etc.). In addition, components (e.g., the frame 142, the forward mount 158, the rearward mount 160, etc.) of the rack 130 and/or components of the hanging basket 135 may be formed with members having other than circular cross-sections, for example, oval cross-sections, square cross-sections, rectangular cross-sections, other polygonal cross-sections, etc.
With reference again to FIGS. 1, 3, and 4, installation of the rack system 100 to the washing assembly 102 will be described. The mounting fixtures 126 and 128 can be connected to the forward and rearward walls 116 and 118 of the tank 104 by fasteners 176. For example, the fasteners 176 may extend through openings formed in each of the base plates 136 of the mounting fixtures 126 and 128 and through corresponding openings in the forward and rearward walls 116 and 118 of the tank 104. Alternatively, the mounting fixtures 126 and 128 may be connected to the walls 116 and 118 of the tank 104 by other mechanical fasteners, by adhesive, by solder, etc. within the scope of the present disclosure. And in other exemplary embodiments, mounting fixtures may be connected to other walls of tanks, for example left and right side walls of the tanks, bottom walls of the tanks, etc. In still other exemplary embodiments, mounting fixtures may be formed integrally, monolithically, etc. with walls of washing assembly tanks. Here, the tank walls may define mounting fixtures for connecting racks to the tanks.
The racks 130, 132, and 134 of the rack system 100 can be connected to the mounting fixtures 126 and 128 at any desired location within the washing assembly tank 104 to accommodate, as necessary, one or more sizes of the sheet pans 106 and 108 to be washed. The illustrated racks 130, 132, and 134 connect to the mounting fixtures 126 and 128 by positioning each of the pins 162 and 172 of the forward and rearward mounts 158 and 160 in the corresponding openings 140 in each of the flanges 138 of the mounting fixtures 126 and 128. These pin-and-opening connections can securely hold the racks 130, 132, and 134 at their desired location within the tank 104 (e.g., during placement of sheet pans 106 and 108 into the rack system 100, during washing operation of the sheet pans 106 and 108, during removing of the sheet pans 106 and 108 from the rack system 100, etc.). The openings 140 are spaced along each of the mounting fixture flanges 138 such that each of the forward and rearward mounting pins 162 and 172 of each rack 130, 132, and 134 can each be received into one of the openings 140. It should thus be appreciated that the racks 130, 132, and 134 can be connected to the mounting fixtures 126 and 128 at generally any desired location within the washing assembly tank 104 to accommodate, as necessary, different sizes of sheet pans to be washed. In the illustrated embodiment, the openings 140 in the mounting fixtures 126 and 128 are spaced apart along the flange 138 by a distance of about 0.5 inches (1.3 centimeters), and the two forward mounting pins 162 and the two rearward mounting pins 172 are each spaced apart by a distance of about 3.0 inches (7.6 centimeters). In other exemplary embodiments, rack systems may include racks with mounting pins and/or mounting fixtures with openings spaced differently than disclosed herein.
One or more of the racks 130, 132, and 134 connected to the mounting fixtures 126 and 128 can be adjusted within the washing assembly tank 104 from one location to another location as desired. For example, the pins 162 and 172 of the respective forward and rearward mounts 158 and 160 of one or more of the racks 130, 132, and 134 can be removed from the respective mounting fixture openings 140 in which they are received. The racks 130, 132, and/or 134 can then be adjusted as desired (e.g., moved from a first location to a second location relative to the mounting fixtures 126, 128, etc.). And the pins 162 and 172 of the respective forward and rearward mounts 158 and 160 of the racks 130, 132, and/or 134 can then be positioned in the proper mounting fixture openings 140 (e.g., at the second position, etc.). Adjusting one or more of the racks 130, 132, and 134 may be done, for example, to properly locate one or more of the racks 130, 132, and 134 to receive the sheet pans 106 and 108 to be washed, to accommodate different sized sheet pans from one washing cycle to another washing cycle, etc.
In the illustrated rack system 100, the racks 130, 132, and 134 may be resiliently flexible. The frame 142, the forward mount 158, and/or the rearward mount 160 of each rack 130, 132, and 134 may be flexed to provide room to move the mounting pins 162 and/or 172 into the respective mounting fixture openings 140 to connect the racks 130, 132, and 134 to the walls 116 and 118 of the tank 104 (e.g., via the openings 140 in the mounting fixtures 126 and 128, etc.). The resilient flexibility of the racks 130, 132, and 134 may also allow the frame 142, the forward mount 158, and/or the rearward mount 160 to be flexed to provide room to move the mounting pins 162 and/or 172 out of the respective mounting fixture openings 140 to disconnect the racks 130, 132, and 134 from the walls 116 and 118 of the tank 104 (e.g., from the openings 140 in the mounting fixtures 126 and 128, etc.).
The sheet pans 106 and 108 to be washed may be placed in the installed rack system 100 by sliding each sheet pan 106 and 108 between support sections 144 of two adjacent racks 130, 132, or 134. In the illustrated embodiment, for example, sheet pans 106 are received between rack 130 and rack 132 in a generally widthwise orientation, and sheet pans 108 are received between rack 132 and rack 134 in a generally lengthwise orientation. Racks 130 and 132 are thus connected to the mounting fixtures 126 and 128 such that a spacing between the racks 130 and 132 closely matches a width dimension of sheet pans 106. For example, the width dimensions of the sheet pans 106 may be sized up and then used to determine proper placement of the racks 130 and 132 to accommodate the sheet pans 106 therebetween. And rack 134 is connected to the mounting fixtures 126 and 128 such that a spacing between racks 132 and 134 closely matches a length dimension of the sheet pans 108. For example, the length dimensions of the sheet pans 108 may be sized up and then used to determine proper placement of the rack 134 relative to rack 132 to accommodate the sheet pans 108 therebetween. Sheet pans 106 can be slid between support sections 144 of racks 130 and 132 with one side of each sheet pan 106 received between adjacent support sections 144 of rack 130, and an opposite side of each sheet pan 106 received between corresponding adjacent support sections 144 of rack 132. And sheet pans 108 can be slid between support sections 144 of racks 132 and 134 with one side of each sheet pan 108 received between adjacent support sections 144 of rack 132 (together with one side of each sheet pan 106), and an opposite side of each sheet pan 108 received between corresponding adjacent support sections 144 of rack 134.
The connection members 152 and 154 extending through the support sections 144 of each rack 130, 132, and 134 generally divide each support section 144 widthwise in half such that each of the racks 130, 132, and 134 can receive sides of two different sheet pans 106 and 108 into the racks 130, 132, and 134 on opposite sides of the connection members 152 and 154. The sides of the sheet pans 106 and 108 received between the adjacent support sections 144 of each rack 130, 132, and 134 may abut against the connection members 152 and 154 within the racks 130, 132, and 134. This may help stop the sheet pans 106 and 108 from extending laterally through the each rack 130, 132, and 134 between the support sections 144 (e.g., when they are placed in the racks 130, 132, and 134, during washing operation, etc.). Thus, connection members 152 and 154 may, for example, be viewed as stops of the rack system 102.
Once the sheet pans 106 and 108 to be cleaned are placed in the rack system 100, the washing assembly 102 may be operated to clean the sheet pans 106 and 108. The washing assembly tank 104 may be filled to an operating level with cleaning fluid, and the one or more pumps can be operated to pump the fluid from tank 104 through the inlet 110 to the outlets 112. The sheet pans 106 and 108 and the rack system 100 can be generally oriented within the tank 104 so that fluid from the outlets 112 is dispersed into the tank 104 in a direction that allows the fluid to move generally between the sheet pans 106 and 108 (e.g. the support sections 144 of each of the racks 130, 132, and 134 holding the sheet pans 106 and 108 can be generally aligned generally transverse to the fluid being dispersed into the tank 104). This orientation may substantially improve cleaning operation because the moving fluid can pass between the sheet pans 106 and 108. In addition, the sheet pans 106 and 108 may be at an angle in the rack system 100 so that the operating level of the cleaning fluid substantially covers the sheet pans 106 and 108. When washing operation is finished, the sheet pans 106 and 108 may be removed, and the rack system 102 may be adjusted, for example, to accommodate different kitchenware for subsequent washing operations.
In the illustrated embodiment, the hanging basket 135 may be connected to the washing assembly tank 104 via the second mounting fixture 128 of the rack system 100. The hanging basket 135 may include one or more hooks configured (e.g., sized, shaped, constructed, etc.) to be received into the openings 141 of the second mounting fixture 128 to connect the hanging basket 135 to the tank 104. The hanging basket 135 may be located as desired within the tank 104 by positioning the one or more hooks of the hanging basket 135 in one or more of the plurality of openings 141 of the second mounting fixture 128. The hanging basket 135 may also be adjusted within the tank 104. For example, the hanging basket 135 may be disconnected from the second mounting fixture 128 by removing the one or more hooks from the openings 141 of the second mounting fixture 128. The hanging basket 135 may then be adjusted as desired, and subsequently reconnected to the tank 104 at the second mounting fixture 128 in the adjusted position. In the illustrated embodiment, the hanging basket 135 is disclosed as connectable to the second, rearward mounting fixture 128. In other exemplary embodiments, hanging baskets may be connectable to a first, forward mounting fixture, or hanging baskets may be connectable to both a first, forward mounting fixture and a second, rearward mounting fixture.
In other exemplary embodiments, rack systems may include racks that are integral with walls of washing assembly tanks. For example, at least one of the walls of a washing assembly tank may be configured (e.g., sized, shaped, constructed) to receive at least part of kitchenware to be washed in the tank. In one exemplary embodiment, a first rack of a rack system includes multiple aligned and generally parallel slots, grooves, etc. formed in a wall of a washing assembly tank. The slots, grooves, etc. are spaced apart and can define, for example, a gap sized to receive, for example, a side edge of a sheet pan into the rack. And a second rack of the rack system is spaced apart from the first rack to receive an opposite side edge of the sheet pan. The sheet pan can be held between the racks for washing in the tank.
In further exemplary embodiments, rack systems may include racks with grooves, channels, etc. formed therein to receive kitchenware in the grooves, channels, etc. to hold the kitchenware in the racks.
