Definitions

  • the present invention relates to a multifunctional partition dishwasher.
  • Known dishwashers usually include in their tub a sliding lower basket not adjustable in height, and a sliding upper basket often adjustable in height in two positions.
  • the guide paths of the rollers of their upper dish basket consist of rails fixed at two different levels on the inner surface of their opposite parallel side walls. These rails strike the cost price of these dishwashers and the method of fixing these rails also poses problems relating to the tightness of the tank of these devices.
  • the cutlery subjected to washing is stored in perforated cutlery baskets, arranged in dish baskets and sprinkled, from bottom to top, with liquid by a watering reel rotating below these baskets. dishes.
  • the openings in the funds of these baskets cutlery is often small so as not to let the cutlery escape.
  • the jets of coolant hardly reach the cutlery with low vigor. It turns out that the cutlery is frequently poorly washed in known dishwashers.
  • kitchen utensils can be washed together with the dishes.
  • their washing results are usually poor or even poor.
  • the food products in the utensils are often heated or brought to relatively high temperatures for cooking. These food products under the effect of heat are physically transformed and tend, depending on their nature, to stick, become encrusted, dry out, or carbonize on the wall of the utensils.
  • the resulting dirt is often abundant and very adherent.
  • soiling from utensils is generally more difficult and takes longer to remove.
  • the combined effect of the temperature, the pressure of the washing liquid, the aggressiveness of the detergent and the duration of the washing usually makes it possible to remove dirt from the dishes and obtain good washing results.
  • the temperature and the pressure of the washing liquid in these known dishwashers cannot be adjusted beyond the maximum or limitable values that can be supported by the dishes without running the risk of damaging them.
  • the maximum values or limits of temperature and pressure of the washing liquid accepted in known dishwashers often prove to be insufficient in the removal of soiling from the utensils for reasonable washing times. Poor or poor washing results for kitchen utensils in known dishwashers are likely to result.
  • the aim of the present invention is to avoid these drawbacks and makes it possible to produce an economical multifunctional partition dishwasher, capable of effectively washing both dishes and utensils and of obtaining excellent results on a regular basis. wash for reasonable wash times.

  • the sliding partition 14 Since the soiling of the utensils is generally abundant and resistant to washing, during operation of the machine 1 by virtue of the sliding partition 14 which serves as a barrier, the loose soiling of the utensils in the compartment 12 does not contaminate the dishes in compartment 11. If the temperature and pressure of the washing and rinsing liquid for utensils in compartment 12 are high and above the limits of temperature and pressure bearable by the dishes, the sliding partition 14 prevents any damage caused by this liquid at high temperature and pressure, to the dishes in the compartment 11.
  • the multifunction sliding partition 14 is adjustable in height in the tank 3, which allows an advantageous adaptation of the volumes of the compartments 11 and 12 to the quantities of dishes and utensils subjected to washing.
  • the multifunction partition 14 includes a central surface closed to any passage of liquid and dirt particles between the two compartments 11 and 12, and front and rear edges open only to one passage, on the one hand of the steam between the two compartments 11 and 12, and on the other hand, liquid and dirt particles from the dishwashing compartment in the utensil washing compartment 12.
  • Such a partition 14 allows the dishwasher and utensils 1 to be used , several methods of washing utensils and dishes and obtaining regular and excellent washing results.
  • the washing of the dishes and that of the utensils are carried out simultaneously in their respective compartments, at the same liquid temperature but at different liquid pressures, a pressure less than or equal to a limit value that can be supported by the dishes for washing dishes and a pressure higher than this limit value for washing utensils.
  • the dishwasher and utensils 1 then comprises, on the one hand, circuits for liquid spraying the utensils 18 and the dishes 20 respectively dimensioned in a known manner or provided with a known system for adjusting the pressure and on the other hand share an operating program ensuring an implementation of this process.
  • the washing of the utensils is carried out first alone in a first phase for a predetermined time, then in a second phase in parallel with washing the dishes.
  • washing of utensils is carried out at the same pressure and the same liquid temperature as those for washing dishes.
  • the dishwasher and utensils 1 then comprises on the one hand in the coolant circuits 18, 20 an all-or-nothing flow control device not shown such as a solenoid valve, a valve which normally opens these two circuits 18 , 20 at a preset time and for a predetermined time closes the only circuit for spraying the dishes 20, the utensils being then only subjected to washing and on the other hand an operating program ensuring an implementation of this process .
  • an all-or-nothing flow control device not shown such as a solenoid valve, a valve which normally opens these two circuits 18 , 20 at a preset time and for a predetermined time closes the only circuit for spraying the dishes 20, the utensils being then only subjected to washing and on the other hand an operating program ensuring an implementation of this process .
  • the washing of the utensils is carried out first alone in a first phase for a predetermined time at a pressure and a liquid temperature respectively higher than the pressure and temperature limit values that can be supported by the dishes and then in a second phase in parallel with washing the dishes at the same pressure and the same liquid temperature as those for washing the dishes.
