Definitions

  • the present invention is related to a dishwashing machine with enhanced washing performance by the contribution of a mechanism of valves controlling the flows in the washing lines independently from each other, and with reduced consumption values.
  • the crockery placed in the washing racks is washed by means of the washing water sprayed from the washing mechanisms arranged above and below these racks.
  • Water passing through the pipes connected to these washing means is circulated throughout the system by means of a pump.
  • the normal programs consist of six successive steps, namely; "pre-washing, main washing, regeneration, rinsing, warm rinsing, drying".
  • the drying and regeneration steps are auxiliary steps and during the other successive washing steps in normal programs, a total amount of washing water required for each step is taken-in according to the current loading of the machine.
  • washing cycle is completed.
  • washing operation is realised at both washing racks.
  • a dishwashing machine disclosed in the German Patent Application No. DE 4243869, wherein only the upper washing rack is loaded with the crockery and the upper washing mechanism is operated, taking a half washing capacity as the basis, in order to reduce water, detergent, time and energy consumption, the lower washing mechanism is closed by a valve.
  • Both washing racks are manufactured similarly and each rack is arranged according to a half dishwashing capacity. The user has to place the crockery on the upper rack.
  • this patent application it has been proposed to use another valve to control the upper washing means. This valve may be closed instead of the other one that is used to control the lower washing means as an alternative. In this way, the lower washing means will be operated and the crockery shall be placed only on the lower washing rack.
  • the object of the present invention is to control the washing mechanisms of the dishwashing machine, at a desired program step independently from each other using separate valves for each one. Another object of the invention is to control each washing mechanism continuously and independently from each other according to the program sequences and washing steps.
  • Yet another object of the invention is to control the operations of the washing racks according to the program selections of the main program unit, by the evaluation of the information obtained by the sensors during the washing steps.
  • Another object of the present invention is to control the operation of the washing mechanisms directly in connection with the washing program.
  • Another object of the present invention is to allow the user to control the washing rack directly by using the option and program selection buttons.
  • Yet another object of the present invention is to provide the user with such possibilities as being able to load all washing racks as he/she desires and as required, to wash the dirtiest and massive crockery at the lower, and less dirty and smaller crockery at the upper rack.
  • Another object of the invention is to provide a better cleaning of the detergent present in the detergent dispenser system.
  • Figure 1 - is the schematic view of the prior art dishwashing machine.
  • Figure 2 - is the schematic view of the implementation in the dishwashing machine of the present invention.
  • Figure 3- is the cross section view of the integral (incorporated) container in the dishwashing machine of the present invention.
  • the water system of the dishwashing machines consists of a sump (l)-a pump reservoir-wherein the washing water is collected, a pump (2) which circulates it throughout the system sucking the water from the sump (1), conduits (4,10,11) through which the water is transmitted and the washing mechanisms, (7 and 9) which spray the liquid onto the loaded racks. Water sprayed from the washing mechanisms (5,7 and 9) comes back to the sump (1) by hitting the crockery in the racks (6 and 8) and the walls of the washing tub.
  • the equipment disclosed in this invention to provide the aimed properties and controls, consist of an inlet (12) connected to the delivery side of the washing pump, two outlets (13 and 14) opening to the upper and lower washing mechanisms (7 and 9), control mechanisms (15 and 16) of the said washing mechanisms (13 and 14), components (17 and 18) that in turn control the said control mechanisms (15 and 16), a third outlet (20) wherein a water directing device (19) and a controller component (25) are mounted in front of the container where both valve mechanisms are present, and the washing water is directed towards another mechanism for a different purpose, a fourth outlet (21) for the uppermost spraying component (5), which is not controlled or which can be controlled by an additional valve mechanism, and a container (3) wherein all these inlets and outlets are integrated with their control mechanisms.
  • the present invention provides a facility and flexibility of production by designing dishwashing machines of various types and technical characteristics on a single device with regard to the water system.
  • the most suitable point for the control of the water lines would be the pump outlet.
  • the flow rate that is required for each washing mechanism is controlled by means of a valve mechanism (15 and 16) situated at the pump outlet, by opening and shutting-off using an electrical or pneumatic component (17 and 18) that drives the said mechanism.
  • the said control may be in the form of controlling the section area of the water line and therefore of the required flow rate, at determined ratios.
  • outlets can also be controlled by means of various flap combinations of valve mechanisms and mechanical connections by using a smaller number of components. Or else, all outlets can be commanded by a control cap, the position of which is specified by a code and by a single electrical component that drives the said control cap.
  • the decreases in the pressure due to the parameters of the water system components and the nozzle output flow rates required for the washing process, are provided by the pump.
  • the system flow rates under normal operating conditions are made in such a manner that they will not allow pump air suction.
  • the washing mechanisms disclosed in this invention are controlled in order to detect and eliminate the above described pressure fluctuations. For this reason, one or more of the physical parameters having influence on the washing system are continuously controlled by means of sensors. When these measured values exceed the limit values, the appropriate washing mechanism is shut-off by the main control unit to bring the system close to the optimum working point and thus the washing performance is kept at the desired level.
  • This control is made to provide the decrease of the fluctuations to be held below the defined limits, in case the fluctuation occurring at the pump outlet pressure exceeds the peak values, by reducing the flow rate to the upper or lower washing rack to a certain extent and by measuring the pressure values again.
  • the washing mechanisms can also be controlled directly by the main control unit, according to the washing cycle steps without requiring the control of the washing system physical parameters.
  • a predetermined, smaller amount of water is taken in instead of a maximum amount of water.
  • each washing mechanism starts to operate in a predetermined order required for certain steps in the program.
  • the user may have the opportunity to control directly the operation of the washing mechanisms (7 and 9).
  • the user presses the intense program option button if the crockery with heavy dirt such as pots and pans will be washed.
  • the control system increases the flow rate and pressure of the lower mechanism and provides an optimum washing efficiency, by shutting off the upper mechanism continuously or at certain steps of the washing cycle.
  • the decomposition and a complete cleaning of the detergent contained in the detergent dispenser component is provided by operating only the lower washing mechanism (9), at the beginning of the program step.

Abstract

L'invention concerne un lave-vaisselle capable de réguler les débits dans le lignes de lavage de manière indépendante, au moyen de différentes combinaisons de clapets de retenue, afin de réguler les fluctuations survenant dans la pression de pompe et, par conséquent, dans les débits, à la suite des variations des paramètres d'eau de lavage dues à des facteurs tels que la décomposition de la saleté sur la vaisselle à laver, l'augmentation de la température et l'utilisation de produits chimiques. On peut aussi régler et réduire la consommation d'eau et d'énergie au moyen de commandes mécaniques, de composants pneumatiques et électriques et des programmes de fonctionnement choisis par l'utilisateur.
