Hoffman, Pequannock, N.J., assignor to General Electric Company, a corporation of New York Filed Dec. 26, 1967, Ser. No. 693,643 Int. Cl. B08b 3/00 US. Cl. 134154 10 Claims ABSTRACT OF THE DISCLOSURE A track assembly for supporting dishracks in a dishwasher is convertible for use in either an in-line or a corner type dishwasher installation. The track assembly is a unitary structure including four tracks disposed in a rectangle and two guide rails one of which is fixed on one of the tracks. The track assembly includes means for detachably mounting the other guide rail on either of two different tracks so that the two guide rails can be associated with either two parallel tracks or two perpendicular adjacent tracks. The track assembly includes mounting feet depending from its corners permitting releasable mounting of the assembly, and carries a plurality of splash bafiles for shielding the dishwasher doors from water spray during the washing operation.
BACKGROUND OF THE INVENTION Dishwashing machines ordinarily include track assem- The commercial type dishwashers ordinarily include a housing with two open sides and associated doors serving respectively as entrance and exit passages through which the dishrack is inserted and withdrawn into and out of the housing. In certain installations a so-called in-line machine is employed wherein the entrance and exit passages are oppositely disposed requiring straight line movement of the dishrack relative to the housing. In these installations the track assembly includes two spaced parallel tracks with fixed guide rails to permit straight line movement of the dishrack. Certain other installations require a so-called corner machine wherein the entrance and exit passages are located at right angles. In this type installation a different track assembly is employed which has four tracks with two guide rails fixed at right angles to permit the necessary right angle movement of the dishrack. Examples of these different type dishwashers and their different associated track assemblies are disclosed in US. Patent 2,051,233.
Heretofore, there has not been available a single basic track assembly design which is readily convertible for use with either an in-line or a corner type dishwasher installation. Provision of such a basic design is desirable in that it permits reduction in the inventory of track assemblies which must be stocked. Further, such a basic track assembly facilitates the design of a universal dishwasher which has three entrance and exit passages and which is usable selectively either in an in-line or a corner installation. Thus, such a universal dishwasher and basic track assembly permits a customer to readily change his installation from in-line to corner" or viceversa using the same machine and the same track assembly with a simple converting operation of the track assembly.
It is necessary that commercial dishwashers be maintained in a sanitary condition which requires periodic cleaning of the interior thereof and the interior parts such as the track assembly and splash baflles usually employed 3,465,763 Patented Sept. 9, 1969 to shield the doors from water spray during the washing operation. Heretofore, the cleaning of the machine and its internal parts have been difficult and time consuming inasmuch as many of the internal parts have not been readily removable. It is thus seen to be desirable that provision be made for mounting the track assembly and the splash bafiles so that they can be readily removed from the machine to permit cleaning of such parts as well as to facilitate cleaning of the dishwasher interior.
OBJECTS OF THE INVENTION It is therefore a primary object of the invention to provide a novel and improved basic unitary track assembly which is readily convertible for use in either an inline or a corner type dishwasher installation.
It is another object of the invention to provide a unitary track assembly as defined in the proceding object which carries a plurality of splash baffles and which is mounted within a dishwasher in a manner permitting its easy removal therefrom for cleaning or other purposes.
SUMMARY OF THE INVENTION In carrying out the invention in one preferred form, a unitary track assembly for supporting dishracks is provided including a pair of spaced parallel first tracks and a pair of spaced parallel second tracks perpendicular to and connecting the first tracks. The tracks include track surfaces which are generally coplanar for supporting a suitable dishrack containing dishes or other articles to be washed. The assembly includes two guide rails one of which is fixed on one track of the first pair of tracks adjacent the outer edge of the associated track surface. Means are provided on the assembly for detachably mounting the second guide rail in association with either the other track of the first pair or one track of the other pair to permit ready convertibility of the assembly for use either in an in-line or a corner installation.
The assembly is releasably mounted in a dishwasher by means of a plurality of depending feet which freely rest upon a corresponding number of supporting brackets in a dishwasher. Also carried by the track assembly are three splash bafiles which depend angularly away from the assembly for extension toward the bottom portions of the dishwasher doors to shield the doors from spray emanating from a water spray pipe in the machine.
Other objects and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings in which:

DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawings, there is illustrated in FIGURE 1 a dishwashing machine represented generally by the numeral including a housing 11 having a plurality of open sides serving as entrance and exit passages for permitting movement of a dishrack into and out of the housing. While the housing 11 may have two open sides, it preferably has three open sides permitting selective installation of the machine for either in-line or corner operation. In FIGURE 1 the machine 10 is shown installed in the corner of a room.
Referring to FIGURE 2, the machine 10 includes an open side 13 having a vertically movable door 14 associated therewith, the remaining two open sides being respectively adjacent the open side 13 to the left thereof, and opposite the open side 13 and having doors 15 and 16 associated therewith. The corner installation of FIG- URE 1 includes a pair of right angle tables 17 and 18 associated respectively with two adjacent open sides of the machine such that a suitable dishrack 19 containing dishes 20 and supported on the table 17 is movable into the machine in the direction of the arrow 21 through the open side 13 when the door 14 is elevated, and is movable out of the machine in the direction of the arrow 22 through the adjacent open side when the door 15 is elevated. It is understood that the directions of movement of the dishrack 19 can be reversed from those indicated by the arrows 21 and 22. As shown in FIGURE 2, the machine 10 is disposed for in-line operation and to this end is associated with two longitudinally spaced tables 24 and 25. The table 24 supports a suitable dishrack (not shown) which is movable in the direction of the arrow 26 into the machine through the open side 13 and which is removed from the machine after the cleaning operation through the opposite open side along the table 25 in the direction of the arrow 27. Here again the direction of movement of the dishrack can be reversed from the direction indicated by the arrows 26 and 27.
In accord with the present invention an improved unitary track assembly is provided which is readily convertible for use in either an in-line or a corner type dishwasher installation. To this end, the track assembly includes a guide rail which can be detachably mounted selectively in association with either of two adjacent tracks such that an associated dishrack can be moved relative to the housing in either a straight line path or a right angle path. The improved track assembly is shown in FIGURES 2, 3 and 4 represented generally by the numeral 28 and is in the form of a unitary frame of generally hollow rectangular configuration.
As shown in FIGURE 2, the assembly 28 is mounted within the machine housing above a water spray pipe 29 for removably supporting a dishrack in position to receive spray from the spray pipe 29. An additional spray pipe (not shown) may be located within the housing above the assembly 28 to provide upper and lower wash and rinse spray pipes as desired. The spray pipes are preferably mounted for rotation about vertical axes so as to completely envelop the dishrack and its contents with wash and rinse fluid.
In order to support the dishrack and to permit its movement relative to the machine housing, the assembly 28 includes four tracks arranged in a rectangular array and comprised of a pair of first spaced parallel tracks 30 and 31 and a pair of second spaced parallel tracks 32 and 33 extending generally perpendicular to and connecting the first tracks 30 and 31. The tracks 32 and 33 are in the form of separate supports which are connected to the tracks 30 and 31 in any suitable manner such as by welding along meeting edges of the tracks and supports as indicated by the letter W in FIGURE 3. The welds are ground smooth so that the tracks 30, 31, 32 and 33 have upper track surfaces which are substantially coplanar.
In order to guide the dishrack for sliding movement relative to the track assembly, the assembly includes a pair of guide rails 34 and 35 associated with selected ones of the tracks 30, 31, 32 and 33. As best shown in FIGURES 3 and 4, the guide rail 34 is associated with the track 30 and is preferably an integral part thereof extending upwardly from the outer edge of the associated track surface generally perpendicular thereto. In accord with the invention the second guide rail 35 is adapted for selective detachable mounting in association with either the track 31 or the track 32. To this end, first means are provided for detachably mounting the rail 35 adjacent the outer edge of the track surface of the track 31, and second means are provided for detachably mounting the guide rail 35 adjacent the outer edge of the track surface of the track 32. The first mounting means preferably comprises a depending lateral flange 37 integral with the track 31 and the second mounting means similarly comprises a depending lateral flange 36 integral with the track 32. The flange 37 extends downwardly and away from the track 31 and includes a plurality of spaced openings 38. The flange 36 similarly extends downwardly and away from the track 32 and includes a plurality of openings (not shown).
As best shown in FIGURE 4, the detachable guide rail 35 includes a flange 39 integral with and depending from the main section of the guide rail. The flange 39 includes a plurality of openings 40 as shown in FIGURE 3 which are aligned with the openings 38 in the flange 37 of the track 31 when the guide rail 35 is operatively positioned in association with the track 31 with its flange 39 hearing against the upper surface of the flange 37 as best shown in FIGURE 4. The rail 35 is secured to the track 31 by releasable fasteners such as screws 41 which extend through the aligned openings 38 and 40. When the guide rail 35 is mounted in association with the track 31 as shown in FIGURE 4, it is in spaced parallel relation with the guide rail 34 to guide the dishrack for straight line movement along the tracks 30 and 31 in the direction of the arrows. This arrangement is employed in an in-line installation as shown in FIGURE 2.
In order to convert the track assembly for use in a corner installation as shown in FIGURE 1, it is only necessary to detach the guide rail 35 from the track 31 and remount it in association with the track 32. This is quickly accomplished by removing the screws 41 and placing the rail 35 in association with the track 32 in the same manner in which it was associated with the track 31. The screws 41 are then inserted through the aligned openings of the rail 35 and the flange 36 on the track 32. Such arrangement is illustrated in FIGURE 3 and is effective to guide the dishrack for movement along a right angle path. The dish rack is slid onto the tracks 30 and 31 by movement thereof in the direction of the right-hand arrow in FIGURE 3 and is guided into position by the rail 34 until it abuts against the rail 35. When it is desired to remove the dishrack from the machine, it is moved in the direction of the left-hand arrow in FIG- URE 3 along the tracks 32 and 33, the dishrack being guided for such movement by the rail 35.
In accord with the invention the assembly 28 is releasably mounted within the machine housing so as to permit its ready removal from the housing for cleaning or other purposes. To this end, the assembly 28 is provided with a plurality of support feet shown in FIG- URES 3 and 4 as comprising four support feet 42, 43, 44 and 45 disposed at the corners of the assembly. The support feet preferably comprise integral extensions of the tracks 30 and 31. Thus, the feet 42 and 43 are in the form of longitudinal extensions of the track 30 formed to depend angularly from the ends of the track 30. Similarly, the feet 44 and 45 are integral longitudinal extensions of the track 31 formed to depend angularly from the ends of such track. Each of the feet includes a long depending section 46 and a short inturned section 47 as shown in FIGURE 5 with reference to the foot 42.
In order to releasably mount the assembly 28 within the machine housing, four generally L-shaped brackets 48 are mounted by opposed inside walls of the housing just below the opposed open sides 13 and 16. Each of the brackets 48 includes vertically and horizontally extending parts 50 and 51 (FIGURE 5) with the horizontal part 51 serving as a shelf to receive the section 47 of the associated support foot whereby the brackets 48 freely and releasably support the assembly 28 for removal from the housing. FIGURE 2 illustrates the support foot 42 in operative engagement with the associated bracket 48. The assembly 28 is readily removed from the housing simply by lifting the assembly to elevate the support feet clear of the brackets 48 and withdrawing the assembly 28 through one of the open sides 13 and 16.
In accord with a further aspect of the invention, the assembly 28 carries a plurality of splash battles for shielding the lower portions of the doors from spray from the spray pipes during operation of the machine so as to prevent leakage of water outside the machine. As shown in FIGURES 3 and 4, the baflies preferably comprise three baflle plates 52, 53 and 54 associated respectively with the tracks 33, 31 and 32. The baffle plate 52 is preferably welded to the underside of a depending flange 55 integral with the track 33, and the baflle plates 53 and 54 are similarly welded to the undersides of flanges 37 and 36 respectively on the tracks 31 and 32. The baflies include respectively short vertical terminal sections 56, 57 and 58 which lie adjacent the lower portions of the doors 14, 15 and 16 when such are closed so as to shield these door portions from water spray during operation of the machine.
Although the invention has been described with reference to certain specific embodiments thereof, numerous modifications are possible and it is desired to cover all modifications falling within the spirit and scope of the invention.
