Abstract
Abstract of the Disclosure In an apparatus for washing dishes, glasses and the like, the water used for washing and rinsing drains to a collection tank, from which it is extracted by a pump and circulated again through spray means for washing the glasses, etc. At appropriate times a dump valve is opened in the bottom of the collection tank by an automatic timing mechanism and the liquid is dumped quickly into a sump tank below the collection tank, from which it can drain in a slower period of time to the sewer. Means for opening this valve quickly consists of a pivoted arm on which the valve is mounted, the other end of the arm being engaged by a cam member which permits the valve to open at the appropriate time.
The operator is able to observe whether or not additives for the wash and rinse liquid have been added, since the pipes feeding the additives into the collection tank have a visibly-open portion. The water resulting from the last rinse is collected in the collection tank and is employed in the succeeding wash cycle as the wash liquid.
The operator is able to observe whether or not additives for the wash and rinse liquid have been added, since the pipes feeding the additives into the collection tank have a visibly-open portion. The water resulting from the last rinse is collected in the collection tank and is employed in the succeeding wash cycle as the wash liquid.
Description
"7 ~) APPARATUS FOR WASHING DISHES, GLASSES AND THE LIKE
;~ield of the Invention This invention is concerned with improvements in or relating to appara~us for washing dishes, glasses and the like, such as is used as example in restaurants, bars and saloons.
Review of the Prior Art _ Mechanical apparatus is now almost universally used in restaurants, bars and saloons for the washing of the dishes, glasses, etc. involved in the operation. It is preferred by the operator of such an establishment that the apparatus occupies as small a space as possible, and yet be of relatively high capacity 50 as to ensure that washed dishes and glasses are available at all times. One way in which an increase in throughput in the apparatus can be achieved is by shortening the washing and rinsing cycle, but this then results in problems such as disposal in the very brief period of time of the relatively large quantity of water that is used in the washing ancl rinsing periods. Moreover, it is difficult for the operator to know if the required additives are actually being added to the liquids in the operation oE the apparatus.
Definition of the Invention It is therefore an object of the present invention to provide a new apparatus for washing dishes, glasses and the like.
In accordance with the present invention there is provided apparatus for washing dishes, glasses and the like, comprising:-a body receiving a tray of dishes, glasses and the liketo be washed;
. ~
~ . :
:
~ ~ ~8~7~
spray means for spraying the contents of the tray with washing water and subsequently with rinsing water;
a collection tank receiving the water delivered by the spray means;
pump means circulating the liquid from the collection tank to the spray means;
a sump tank disposed at a lower level than the collection tank and connected to a drain;
valve means connecting the collection and sump tanks for dumping the liquid from the collection tank to the sump tank for subsequent draining to the drain; and means for feeding additives to the wash and/or rinse liquid in the collection tank, each said means including a visibly-open pathway portion to permit observation of the flow of such additives.
Description of the Drawings A particular pre~erred embodiment of the invention will now be disclosad by way of example, with reference to the accompanying diagrammatic drawings, wherein:
Figure l is a front elevation of the apparatus;
F-gure 2 is a transverse cross section parallel to the said front elevation and approximately on the line 2-2 of Figure 3:
~ Figure 3 is a plane view of the apparatus of Figures l and 2; and Figure 4 is a side elevation of motor-driven cam actuating mechanism for dump valve means of the apparatus.
Description of the Preferred Embodiment _ ~ _ ., :
.
l ~78~17~
The apparatus of the invention comprises a sheet metal body 10 of approximately square cross section as seen in plan, the upper part of which is provîded with a rotary spray means 12 for washing the underside of a tray (not shown) of dishes, glasses mounted above the spray means. Another spray means will be mounted above the tray in a manner known to those skilled in the art and not illustrated in the present application since the disclosure thereof is not essential to the understanding of the present invention.
The spray means is mounted on a downwardly sloping generally horizontal partition 14 whereby liquid discharged from the spray means drains automatically under gravity into a collection chamber 16. Th~ liquid which drains into the collection chamber is extracted therefrom by a rotary pump 18 driven by a motor 20 and mounted in the hody, this liquid being fed via a pipe 22 to the spray means 12 and by an extension 24 (Figure 3) o~ that pipe to the spray means abov~ and not illustrated.
The collection chamber is divided into two separate portions by means of a divider member ~6, the vertical wall of which is perforated so as to act as a screen filtering out any coarse particles of food, etc., that may have become entrained in the liquid~ A thermometer 28 is provided in one portion of the compartment and a hQater coil 30 is provided in the other portion so as to maintain the water at a desired temperature.
At the start of a washing operation the collection chamber is full of the rinse liquid from the previous washing operation. If however this is the first operation o the day `
., 1 1~81V70 the chamber is fir~t filled with water to the appropriate level so as to provide wash water for the first operation. At the start of the operation the motor 20 is switched on in known manner by an automatic timing circuit, the water which is discharged from the spray means causing the latter to move about its pivot so as~to distribute the water over the glasses, dishes, etc., in the tray.
After a predetermined period of time constituting the washing period a timer~motor 32 begins to rotate whereupon a valve-closing member 34 disengages from a roller 36 and permits a large dump valve 38 to open, causing the cont~nts of-the collection chamber 16 to be delivered rapidly into a sump chamber 40 below the collection chamber, from which the liquid can drain relatively slowly to the sewer by a drain pipe 42.
The sump chamber is also provided with a perforated screen 44 to prevent passage o~ large particles into the sewer.
Referring no~ particularly to Figure 4, in this particular embodiment, the sump valve comprises a relatively large opening 46 in the base of the chamber, ~hich opening is closed by a flexible member 48 backed by a rigid metal member 50.
The resulting valve closure member is carried by one end of a pivot lever 52, the valve being biased into the closed position from the lever by means of a coil spring 54. The other end of the pivoted lever 52 is engaged by a valve operating member consisting of the timer motor 32 which carries on its shaft two cam members consisting of the said closing member 34a and another closin~ member 56. The first member 34 is of relatively .... . .. . . .
l 171~'70 small arcuate extent and is in engagement with the roller 36 at the respective end of the lever while the wash cycle is in process.
A~ter the wash cycle has been operative for a predetermined period of time, the timer motor is operative as described, whereupon the cam member 34 disengages from the roller and the dump valve is opened quickly and ef~ectively to dump the liquid rapidly from the collection tank to the sump tank, much faster than it could otherwise draîn. The valve remains open until the second cam member 56 again engagés the roller and closes the valve for a predetermined period of time during which the pump 18 is again operative to collect water from the collection tank 16 and employ that water for rinsing. The timer motor 32 is arranged so that at the end of its operation cycle the first cam member 3~ is again in engagement with the roller 36 and holds the dump valve closed, whereupon the water that has been supplied ~or rinsing remains in the collection tank 16 and is available or use as wash water for the subsequent operation~
One problem encountered in a glass d~shwashing machine is to ensure that mechanism provided for adding additives to the wash and rinse waters is truly operative, and suitable visual means are provided in the present apparatus. Thus r additives are obtained from containers thereof (not shown) and pumped by respective individual pumps 56, 58 and 60 through respective pipes 6~ and 6~. In the apparatus of the invention these pipes have a visibly-open pathway portion indicated by the reference 66 whereby an operator of the apparatus will see easily and quickly whether or~not the additives are being dispensed into ', ' .~
