Definitions

  • the invention relates to a dishwashing machine and more particularly to a dishwashing machine with a short operating cycle.
  • Dishwashers of known type generally wash twelve place settings in 90 minutes. 5if we remove the pre-wash, we can reduce this time by about 15 minutes.
  • the large capacity of these machines is a drawback for their use in the case of small dishes. This is why, we very recently saw appearing washing machines for only four or five place settings, whose operating cycle was reduced because the quantities of water to be heated are less important than in the machines for twelve place settings.
  • One of the aims of the invention is to provide a dishwashing machine for around five cutlery, the operating cycle of which is short while understanding the complete sequence of the pre-washing, washing, pre-rinsing operations, hot rinse and drying.
  • Another object of the invention is to provide a dish washing machine of reduced dimensions, capable of being simply placed on a kitchen work surface or built in like an oven.
  • the subject of the invention is a dishwashing machine with a short operating cycle, of the type comprising: a tank with electrical resistance for heating the washing water and for drying the washed dishes, a tub with electrical resistance for heating the rinsing water of the dishes, this tank being placed in the upper part of the machine in order to be able to empty into the tank, characterized in that the heating resistance of the tank can only be connected outside periods of operation of the tank resistance.
  • the dishwashing machine 1 is of reduced dimensions, approximately 55 cm in each dimension. It has a tank 2 at its lower part, a door 3 on the front face and a tank 4 at its upper part.
  • This tank 4 has a capacity of approximately 8 liters, that is to say that it can receive a sufficient volume of water to ensure the rinsing of the dishes.
  • It includes a heating resistor 5, and a tube 6 for connection to the tank by constant level overflow. This tube can also be lifted to free a passage to the tank in order to empty the tank.
  • a heating resistor 7 In the bottom of the tank 2 is provided a heating resistor 7, a motor-pump group 8 for feeding the reel 9 and a drain pump 10.
  • the machine is supplied with cold or preferably hot water (around 45 °) by line 11.
  • Two tanks 13 and 14 are provided respectively for the regeneration salt of the resin and the resin itself.
  • Line 11 is divided into two: a line 16, controlled by a solenoid valve 12, to the salt tank 13, and a line 17, controlled by a solenoid valve 15, to the resin tank 14
  • a pipe 18 feeds the tank of the machine 1 under the control of a solenoid valve 21.
  • the pipe 19 has a bypass 20 to feed the tank 4 under the control of a solenoid valve 22.
  • the automatic rinsing and possibly washing machine dispensers have not been shown because they are conventional. They are controlled by the machine program, as well as the solenoid valves and the heating resistors, as well as the motor-pump group of the reel and the drain pump.
  • the operation of the dishwashing machine according to the invention is analyzed in the following manner, assuming at the start the tank 2 empty, the tank 4 full of water, the solenoid valves 12, 15, 21 and 22 closed, the pump 10 and the motor-pump group 8 of the reel stopped, and the resistors 5 and 7 disconnected.
  • the solenoid valves 15 and 21 are open and the drain pump 10 is started. This preliminary rinsing is very short, of the order of a minute, then the solenoid valve 21 closes and the drain pump 10 stops.
  • the solenoid valve 22 opens and the resistor 5 of the tank 4 is connected and begins to heat the water in the tank 4.
  • the water arriving from the line 20 replaces that which was in the tank 4 and which pours into the tank 2
  • the motor-pump group 8 of the reel starts up and provides a pre-wash.
  • the solenoid valve 22 closes. Prewashing takes about one minute. Then the drain pump 10 starts and the tank empties. When the tank 2 is empty the drain pump stops.
  • the solenoid valve 21 opens and feeds the tank 2. During this time, the reel 9 is still rotating. Resistor 5 of the tank is disconnected and that 7 of the tank is connected. When the tank 2 is full, the solenoid valves 15 and 21 close. When the desired washing temperature is reached, the resistance 7 of the tank 2 is disconnected and that 5 of the tank 4 is connected. The detergent is introduced into the tank. The reel 9 continues to rotate for a few minutes to ensure the hot washing of the dishes. During this time, the resistor 5 heats the water in tank 4 to the desired temperature for rinsing. Washing takes about 8 minutes. Then the drain pump 10 starts and empties the tank 2, then it stops.
  • the solenoid valves 15 and 21 open to allow a certain amount of water to enter, then close.
  • the reel 9 always rotates to ensure the pre-rinse which lasts a few tens of seconds. Then the pump 10 starts, empties the tank and then stops.
  • the resistance 5 of the tank is disconnected, and the solenoid valves 15 and 22 are open.
  • the water in the tank is renewed and the very hot water which was contained in tank 4 flows into tank 2.
  • Le. rinse aid is introduced into the tank and the solenoid valves 15 and 22 are closed.
  • the reel 9 always rotates and provides hot rinsing for about a minute and a half.
  • the motor-pump unit 8 then stops and the drain pump 10 starts and empties the tank 2.
  • the solenoid valves 12 and 21 open for a few seconds and then close.
  • the drain pump 10 stops once the tank has been emptied.
  • the resistor 7 of the tank For drying, the resistor 7 of the tank is connected, it heats the tank for about one and a half minutes, then is disconnected. At the end of drying, the program stops.
  • the machine program includes the following stages: preliminary rinsing of the tank, pre-washing, washing, pre-rinsing, rinsing, regeneration of the resin, and hot drying. All of these operations take approximately 15 minutes. During this cycle, the two resistors 5 and 7 are never connected simultaneously to reduce the consumption of electrical energy. Resistor 5 of the tank is connected for approximately 7 and a half minutes, including 1 and a half minutes during the cold pre-wash and 6 minutes during the wash. Resistor 7 is connected for approximately 4 minutes, including 2 and a half minutes at the start of washing and 1 and a half minutes during drying.
  • the arrangement of the container 4 is an essential characteristic of the dishwashing machine according to the invention.
  • This container in fact makes it possible to heat the rinsing water during the pre-washing phase and during part of the washing phase of the machine, and thus shorten the duration of the complete cycle.
  • the dishwashing machine according to the invention therefore makes it possible, without increasing the consumption of electrical energy with respect to known machines, to ensure a complete washing cycle in approximately 15 minutes, for dishes of 4 or 5 place settings.
