Description

LAVAVAJ I LLAS RE QVIBLE APPARATUS Field of the Invention The invention relates generally to equipment for use as commercial dishwashing machines and more specifically smaller individual chamber dishwashers commonly used in smaller commercial kitchens and food preparation areas. The invention involves a combination of a car or table and a dishwashing machine. The car or table comprises a moving car or table with a defined surface angle that deviates from the horizontal that can be used to support objects or items used in conjunction with the machine. An important object is a lamp, made of wire or molded plastic, placed on the cart or table outside the dishwasher to facilitate loading and unloading and movement inside and outside the machine.

Background of the Invention Strict hygiene requirements for commercial kitchens and food preparation areas have resulted in the widespread use of commercial dishwashers. In small commercial kitchens there are high or low temperature batch load machines capable of cleaning an individual grid of plates, cups and silver cutlery at the same time. Since it is necessary to load such a grid, while inside the dishwasher, most users place the machine next to the cabinet, kitchen table or fixed work stations in the area of use. Unfortunately this requires space for machines that can be in smaller stores. Some kitchens will incorporate or, incorporate in the kitchen a sprinkler station of permanent prewash and submerged inside a table or table that can act to hold the objects for insertion inside the machine or can hold the objects recently removed. This allows a user to remove excess food debris from the dish before washing and to allow the handling of hot or moist dishes. This spray station may also comprise a waste disposal to handle the food waste. As long as it is beneficial, such an arrangement consumes valuable space that may not be available. An alternative is needed for such permanent installations. The smallest dishwashers suitable for the home use sliding grilles that are mounted on runners or shelves with wheels. This allows the grid to slide out for easy loading while still holding the grid. Once loaded, the rack can slide into the dishwasher so that the dishes and other parts contained in it can be washed. Larger commercial dishwashers lack this ability, since they generally use a plurality of wire or molded grids. This allows one or more grids to be loaded while a grid is being washed and one or more grids are drying and cooling. As a result, the need for a dishwashing machine remains with a device capable of supporting a rack of frets for convenient loading without consuming excessive space when not in use. Such a device must be easily inserted into the dishwasher in order to consume the minimum space while the tray and the machine are not in use.

BRIEF DESCRIPTION OF THE INVENTION Accordingly, the invention is found in a dishwashing assembly comprising a batch dishwashing machine and a linked table or cart with an upper portion or surface held at an angle that deviates from the horizontal by approximately 5 hours. ° up to 15 ° towards the washing chamber of the machine. This intentional angle or inclination allows ease of loading and unloading and causes any liquid in the tray to drain into the machine. The invention also comprises a method of use in which the table or cart is attached to the machine and an object is inserted or removed from the machine using the table as a support. The table is capable of holding an object or objects such as a molded wire or plastic dish rack in a convenient position outside the dishwasher for loading and unloading. Said carriage comprises a flat tray of a size complementary or greater than said fret grid, wherein the flat tray comprises side and rear barriers capable of supporting the dish grid against substantially horizontal movement and wherein the tray is attached to a support structure such that the tray is held at the desired angle; wherein the support structure is of a suitable weight to allow easy interaction of the tray with the dishwashing machine and comprises means for moving horizontally in relation to the dishwashing machine. The tray is configured to join and be held by the machine.

Brief Description of the Figures Figure 1 is a perspective view of a tray or cart suitable for supporting a fret grill for loading. Figure 2 is an elevation view of the structure shown in Figure 1. Figure 3 is a perspective view of the invention showing the dishwashing machine in combination with the tray or cart of Figures 1 or 2. In this Figure , the carriage is displayed in a charging mode. The dishwasher can be operated with the carriage in this position once the dish rack is slid into the dishwasher. Figure 4 is a perspective view of the invention showing the dishwashing machine in combination with the carriage of Figures 1 and 2. In this Figure, the tray or cart is shown in the storage mode. The dishwasher can not be operated with the carriage in this position.

Detailed Description of the Figures Figure 1 is a perspective view of a carriage 100 of the invention that can be used with a dishwashing machine. An upper tray 10 of a size and shape suitable for supporting a fret grid for loading purposes which is inclined at an angle to the machine is shown (see Figure 2 for the machine and the angle). See also side barriers 120 and rear barrier 130, which serve to prevent an object such as the dish grid (not shown) from sliding out of the support means in an unintended direction. The fourth side of the upper tray 1 10 comprises an edge 141 level with the tray 1 10 and a nozzle 140 that can rest on a complementary surface in the dishwashing machine (see Figure 2 for the complementary surface not observed in this Figure) . Said complementary surface comprises a linear structure which engages the nozzle and provides support along the entire length of the nozzle 140 and the edge 141. The upper tray 1 10 is attached to the rest of the carriage through support articulation means 180. The support 180 is mechanically sufficient to maintain the surface of the table at an angle between 5 ° and 15 °, preferably 6 ° to 12 ° . In an alternative (unobserved) embodiment, the articulation apparatus may comprise a meshing mechanism that allows the tray 1 10 to be held at the desired angle or position without resting on the side of the dishwashing machine. Another alternative (not shown) would be the use of the simple articulation arrangement shown in the Figure together with the simultaneous use of clamps that move from the L-shaped supports 170 to the side barriers 120 to form the angled surface. Those clamps would have suitable detents to hold the tray 1 10 in a position of use. In this case, the car could be used to hold a fret rack in any part of the kitchen, instead of being limited to the placement immediately adjacent to the dishwasher. The fret grid can be brought to the dirty frets, instead of the other way. The car could also be used to hold a rack of frets for cooling and drying, as it could easily be used on either side of the dishwasher. In addition, a clean dish rack can be removed from either side of the dishwasher. The rest of the carriage comprises a vertically oriented U-shaped support structure 160 and a pair of L-shaped support structures 170. These members may be joined together by means known in the art, such as welding, bending or use. of adhesives, means for moving the structure horizontally along the floor are provided with assemblies of slices 150, which may comprise any reasonably sized wheel or slice known to one skilled in the art. The cart itself is preferably made of varnished metal, aluminum or stainless steel, as are most commercial laundry, tarja and dishwashing machines. The carriage assembly provides some opportunities for variation. The modalities shown use tubular stainless steel pieces joined with elbow clamps. Alternatively, the U-shaped support structure 160 could be flexed from a single piece of stainless steel as each L-shaped support structure. As another option, the individual straight pieces of tubular or solid stainless steel could be welded together to form the required structures. Those decisions are within the skill of someone with experience in the technique. Figure 2 is a side elevational view of the carriage 200 of the invention with the tray surface 1 10 at an angle a that is between 5o and 15 °, preferably 6 ° to 12 °. As before, the upper tray 1 10, the side barriers 120 and the rear barrier 130 are observed. A grid 230 (in imaginary line) is shown in the tray 1 10. The fourth side of the upper tray 1 10 comprises a nozzle 140 which rests on a support 240 of the dishwashing machine (shown in imaginary line). The upper tray 1 10 is attached to the rest of the carriage by means of an articulation device 180. In this particular embodiment, the articulation device 180 comprises a vertical articulation 210 which is held in place by the tube 170 and a locking pin. articulation 220. As before, the slice assemblies 150 can comprise any properly dimensioned wheel or slice known to one skilled in the art. Figure 3 is a perspective view of the dishwasher assembly 300 of the invention, in which the carriage is viewed in a loading mode at an angle a to about 9 °. The support structure shown in this Figure differs in some way from that shown in the previous Figures. An upper tray 320, rear barrier 330 and front nozzle 340 is observed. The upper tray is attached to the rest of the support structure by means of articulation assemblies 380 to the L-shaped support structures 370. An object 230 (in imaginary line) such as a grid is shown partially inserted or partially removed from the washing chamber 390 of the machine 300. The remaining element of the supporting structure is the horizontally oriented U-shaped support structure 360. In comparison, the corresponding structural element in Figures 1 and 2 is oriented vertically. The carriage is made mobile by the addition of slice assemblies 350. A batch loading dishwashing machine, such as a low temperature Hobart machine, is also seen in this Figure. While this car is the key to the invention, certain portions of the dishwashing machine must be observed. The carriage is an approximate height but not exactly equal to that of the side panel 342 and the front panel 332, allowing the front nozzle 340 to rest in the dishwashing machine. There is also a side door 382, the rear door 389 and the front door 388, which also comprise a door lift handle 384. Those doors, together with the side panel 342, the front panel 332 and the door supports 386 they define the opening through which the fret grids are to be placed when they are loaded into the flushing chamber 390. The location of this aperture defines a suitable height for the carriage and cooperates also to fix the angle a of the upper tray 310. Another important feature of the dishwashing machine involves its supports, specifically, the legs of the dishwasher 312 and the horizontal clamps 322 cooperate to provide a space into which the car can be inserted when it is not in use in order to save space. In this figure, the car is illustrated in a load or use mode. Figure 4 is a perspective view of the dishwashing assembly 400 of the invention, in which the tray or the carriage is inserted into the washing chamber 390 of the fixed dishwashing machine 300 for storage. An upper tray 310 is seen, which has side barriers 320, rear barrier 330 and front nozzle 340. The upper tray is attached to the rest of the support structure by means of articulation or joint assemblies 380 to the support structures in the form of L 370. The carriage must be adaptable to be inserted into the chamber 390 and withdrawn to the support position of Fig. 3 or removed from the machine together as shown in Figure 2 without support under edge 141. The remaining element of the support structure is the vertically oriented U-shaped support structure 360. The carriage is made mobile by the addition of slice assemblies 350. The carriage support is of a height approximately equal to that of the side panel. 342 and front panel 332, allowing the front nozzle 340 to enter the chamber 390 of the dishwashing machine. There is also a side door 382, the rear door 389 and the front door 388, which also comprise a door lift handle 384. These doors together with the side panel 342, the front panel 322 and the door supports 386 define the opening into which the fret grilles should be placed when loaded. Another important feature of the dishwashing machine involves its supports. Specifically, the legs of the dishwasher 312 and the horizontal clamps 322 cooperate to provide a space within which the carriage can be inserted when not in use in order to save space, as shown in the Figure. When the cart / tray is to be used, the cart or tray is removed from the washing chamber 390 of the dishwashing machine 300. The nozzle 140 of the tray can be brought into close association with the holder 240 of the dishwashing machine for laying trustworthy. Any object that is to be inserted into the machine or removed from the machine can be placed in the tray or cart. The flat surface 10 is ideal for introducing an object such as a grid in a sliding movement along the tray 1 10 into the washing chamber 390 of the dishwashing machine 300. As the machine 300 is operated, the doors 382 , 388 and 389 can be closed to allow safe operation of the machine without removing the tray from the machine holder 240. At the end of the dishwasher cycle, the operations can be repeated with an object or rack for a sufficient number of cycles to complete the washing of dirty objects in a shift or a daily washing regime. When the day's work is completed, the tray or cart can be inserted into the washing chamber 390 of the dishwashing machine 400 for convenient storage during storage periods of the machine. The aforementioned drawings, the explanation and specification describe the elements of the tray or cart, the dishwashing machines and objects to be washed using the cooperation between the tray or grid and the machine. While a variety of embodiments may be made without departing from the spirit and scope of the invention, the invention resides in the claims appended hereinafter.
