Definitions

  • the present invention is related to a time control system for the workin process of a continuous dish-washer by which an essential saving of energy can b achieved.
  • Tunnel dish-washers have a conveyor which carries the dish goods through plurality of zones in the longitudinal direction of the machine. It is piorly know to use devices at the conveyor to start and/or stopp the running of the machine a times when the goods is put into or taken out of the machine. If the running i occasionally interrupted or the function of the machine fails, the washing will b insufficient which is first discovered at the re-use of the goods. On the othe hand, the machine can still be running during periods when dish goods for som reason is not remaining in the machine which means losses of energy. By the wa of a more accurate control of the working process it is possible to eliminate suc drawbacks of the machine.
  • the problem to - drive the machine in well determine intervals is solved without the influence of disturbances in the form of e.g. th opening of doors, a stop of the conveyor etc.
  • a sensin member in the input end of the machine will start an electronic timer which onl counts the time when the machine is runnning and is put to zero as soon a another batch of goods comes into the input end. If no more goods will come th machine is stopped after a predetermined time period.
  • several of the zone in the machine are controlled by its own timer which reduces the use of energy to just the zone where, for the time being, dish goods are treated. The properties which thus make an improvement of the dish washer are more closely defined in the characterizing clause of Claim 1.
  • FIG. 1 a vertical projection of a dish-washer according to the invention
  • Fig. 2 a wiring diagramme of an electronic timer in the dish-washer.
  • a conveyor 10 for conveying dish goods on racks essentially horizontally through the machine.
  • a pre-washing zone 11 begins having a tank 12 in the bottom and a circulation system 13.
  • a drain 14 is provided in this zone through which exceeding liquid passes off.
  • the next zone is the detergent washing zone 15 which has a separate
  • the next step is the post-washing zone 1 with a tank 19 having a drain 20 for exceeding liquid which is passed to th pre-washing zone.
  • the tank 19 is a collecting tank for rinsing liquid from th finishing zone 21 which is the final rinse.
  • the spraying system 22 in this zone i supplied via a heater 23 directly from the water mains and rinses then the good with clean, hot water. This is applicable to a three-tank embodiment of th machine. It may also be carried out as a two-tank embodiment which means tha the detergent washing zone and the post-washing zone are merged. After that rack has left the final rinse it is suitably passed to a roller conveyor where th dish goods are self-drying.
  • the timer has i principle the following working mode.
  • a switch 24 at the input of the machine makes a contact when it is actuate by a rack put into the machine and supplies a start signal on a wire 25 to the inpu of an inverter 26 (a Schmitt trigger) which conducts the inverted and into a rea pulse shape converted signal to a counter 27 which in this example is a standar module MC 14541 according to conventional TTL-technics.
  • the properties of thi counter are important in that the counting speed (the pulse frequency) i externally controlled by an adjustable control circuit 28 and that the counter b an interruption in the control stops at a reached number and proceeds therefro when re-started after the interruption.
  • the output 29 of the counter supplies signal during the time the counting proceeds up to a predetermined number an then the signal ceases.
  • the signal is amplified by transistor 30 which supplies a control current to a relay 31 controlling a rela contact 32 which makes the conveyor start and switches in the driving circuit (not shown) of the first zones 11,15 and eventually 18 of the dish-washer.
  • th pulse frequency is adjustable (here by means of a potentiometer 33 in the contro circuit) the period of driving the machine can be synchronized with the conveyin speed of the rack so that the driving ceases at the moment when the rack leave the last zone of that part of the procedure which is controlled by the timer.
  • the above-said interruptions may occur when someone opens a door of th machine or when the conveyor for some reason is blocked. Against i.a. thes events there are safety contacts 34 positioned in the machine. If any one of thos contacts is closed a zero signal is obtained on the output of the inverter 35 t which a number of diods 36 are connected. These d ⁇ ods will then short-circuit th control signals to the transistor and the counter. The effect of this short-circui will be that the counter stops on the number it has reached and the relay falls s that the driving circuits are broken and the goods is stopped. When the safet contact is re-opened the control signal is re-established so that the count proceeds counting from the reached number and the procedure goes on. During th interruption no part of the procedure is excluded as the rack and the spray syste stand still until the driving is taken up again.
  • the control circuits for the final rinse are substantially identical with th now described device and make thus a doubling of the timer in the foregoing.
  • I the diagramme we therefore use the same reference-numbers on the component as before but with the addition of a ⁇
  • the relay contact 32' thus controls drivin circuits for the conveyor and the spray system 22.
  • th counter 27 has reset circuits which set the counter on zero, when another rack i put into the inlet end and actuates the switch 24.

Abstract

La commande temporelle de fonctionnement d'une machine à laver la vaisselle en continu permet d'économiser de l'énergie grâce à une division du processus de fonctionnement en plusieurs parties de traitement qui ne durent que pendant le traitement des articles de vaisselle. Les parties de traitement sont commandées par des horloges pourvues de circuits de commande et de circuits de réglage sur zéro pour le réglage du temps de fonctionnement, l'élimination des perturbations provoquées par des interruptions, la remise à zéro en entrant les articles de vaisselle, etc.
