Description

L'invention concerne une machine à laver la vaisselle et plus particulièrement une machine à laver la vaisselle à cycle opératoire court.The invention relates to a dishwashing machine and more particularly to a dishwashing machine with a short operating cycle.

Les machines à laver la vaisselle de type connu assurent en général le lavage de douze couverts en 90 minutes. 5i l'on supprime le pré-lavage, on peut réduire ce temps de 15 minutes environ. Cependant, la grande capacité de ces machines est un inconvénient pour leur utilisation dans le cas des vaisselles peu importantes. C'est pourquoi, on a vu apparaître tout récemment des machines à laver la vaisselle pour quatre ou cinq couverts seulement, dont le cycle opératoire a été réduit car les quantités d'eau à chauffer sont moins importantes que dans les machines pour douze couverts.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. However, 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.

L'un des buts de l'invention est de proposer une machine à laver la vaisselle pour cinq couverts environ, dont le cycle opératoire soit court tout en comprenant la séquence complète des opérations de pré-lavage, de lavage, de pré-rinçage, de rinçage à chaud et de séchage.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.

Un autre but de l'invention est de procurer une machine à laver la vaisselle de dimensions réduites, susceptible d'être simplement posée sur un plan de travail de cuisine ou encastrée à la manière d'un four.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.

L'invention a pour objet une machine à laver la vaisselle à cycle opératoire court, du type comportant : une cuve avec résistance électrique pour chauffer l'eau de lavage et pour assurer le séchage de la vaisselle lavée, un bac avec résistance électrique pour chauffer l'eau de rinçage de la vaisselle, ce bac étant placé dans la partie supérieure de la machine pour pouvoir se vider dans la cuve, caractérisée en ce que la résistance de chauffage du bac n'est susceptible d'être branchée qu'en dehors des périodes de fonctionnement de la résistance de la cuve.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.

Selon d'autres caractéristiques de l'invention :

  • - le bac est muni d'un tube assurant par débordement l'alimentation en eau de rinçage de la cuve de la machine, et susceptible d'être soulevé pour assurer le vidage du bac,
  • - l'alimentation de la cuve d'une part, et du bac d'autre part, est assurée par l'intermédiaire de deux électrovannes situées sur deux canalisations différentes et qui ne sont jamais ouvertes en même temps,
  • - la résistance de chauffage du bac est branchée pendant la phase de pré-lavage et pendant la fin de la phase de lavage de la machine, de façon à fournir l'eau chaude de rinçage dès la fin de la phase de lavage, et raccourcir ainsi le cycle de fonctionnement de la machine.
According to other characteristics of the invention:
  • - the tank is provided with a tube ensuring by overflow the supply of rinsing water to the tank of the machine, and capable of being lifted to empty the tank,
  • - the supply of the tank on the one hand, and of the tank on the other hand, is ensured by means of two solenoid valves located on two different pipes and which are never opened at the same time,
  • - the heating resistance of the tank is connected during the pre-washing phase and during the end of the washing phase of the machine, so as to provide hot rinsing water at the end of the washing phase, and shorten thus the operating cycle of the machine.

D'autres caractéristiques ressortiront de la description qui suit faite avec référence au dessin annexé sur lequel on peut voir un schéma simplifié correspondant à une vue en coupe partielle d'une machine à laver la vaisselle selon l'inventionOther characteristics will emerge from the description which follows, made with reference to the appended drawing in which a simplified diagram can be seen corresponding to a view in partial section of a dishwashing machine according to the invention.

En se reportant au dessin, on peut voir que la machine 1 à laver la vaisselle selon l'invention est de dimensions réduites, environ 55 cm dans chaque dimension. Elle présente une cuve 2 à sa partie inférieure, une porte 3 sur la face avant et un bac 4 à sa partie supérieure. Ce bac 4 a une contenance de 8 litres environ, c'est-à-dire qu'il peut recevoir un volume d'eau suffisant pour assurer le rinçage de la vaisselle. Il comporte une résistance de chauffage 5, et un tube 6 de raccordement à la cuve par débordement à niveau constant. Ce tube peut d'ailleurs être soulevé pour libérer vers la cuve un passage afin de vider le bac.Referring to the drawing, it can be seen that the dishwashing machine 1 according to the invention 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.

Dans le fond de la cuve 2 est prévue une résistance de chauffage 7, un groupe moto-pompe 8 pour l'alimentation du moulinet 9 et une pompe de vidange 10.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.

L'alimentation en eau froide ou de préférence chaude (45° environ) de la machine a lieu par la canalisation 11.The machine is supplied with cold or preferably hot water (around 45 °) by line 11.

Deux bacs 13 et 14 sont prévus respectivement pour le sel de régénération de la résine et la résine elle-même.Two tanks 13 and 14 are provided respectively for the regeneration salt of the resin and the resin itself.

La canalisation 11 se divise en deux : une canalisation 16, contrôlée par une électrovanne 12, vers le bac à sel 13, et une canalisation 17, contrôlée par une électrovanne 15, vers le bac à résine 14 Entre le bac à sel 13 et le bac à résine 14 est disposée une canalisation 18. A la sortie du bac à résine 14, une canalisation 19 alimente la cuve de la machine 1 sous le contrôle d'une électrovanne 21. La canalisation 19 présente une dérivation 20 pour alimenter le bac 4 sous le contrôle d'une électrovanne 22.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 Between the salt tank 13 and the resin tank 14 is arranged a pipe 18. At the outlet of the resin tank 14, a pipe 19 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.

Les distributeurs automatiques de produit de rinçage et éventuellement de lavage n'ont pas été représentés, car ils sont classiques. Ils sont commandés par le programme de la machine, de même que les électrovannes et les résistances chauffantes, ainsi que le groupe moto-pompe du moulinet et la pompe de vidange.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.

Le fonctionnement de la machine à laver la vaisselle selon l'invention s'analyse de la manière suivante, en supposant au départ la cuve 2 vide, le bac 4 plein d'eau, les électrovannes 12, 15, 21 et 22 fermées, la pompe 10 et le groupe moto-pompe 8 du moulinet arrêtés, et les résistances 5 et 7 débranchées.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.

Pour assurer le rinçage préalable de la résine et éliminer le sel qui a été introduit dans le bac à résine 14 au cycle précédent, les électrovannes 15 et 21 sont ouvertes et la pompe de vidange 10 est mise en marche. Ce rinçage préalable est très court, de l'ordre de la minute, puis l'électrovanne 21 se ferme et la pompe de vidange 10 s'arrête.To ensure the preliminary rinsing of the resin and remove the salt which was introduced into the resin tank 14 in the previous cycle, 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.

Pour le pré-lavage, l'électrovanne 22 s'ouvre et la résistance 5 du bac 4 est branchée et commence à chauffer l'eau du bac 4. L'eau qui arrive de la canalisation 20 remplace celle qui était dans le bac 4 et qui se déverse dans la cuve 2 Le groupe moto-pompe 8 du moulinet se met en marche et assure un pré-lavage. Lorsque l'eau du bac 4 est entièrement remplacée, l'électrovanne 22 se ferme. Le pré-lavage dure environ une minute. Puis la pompe de vidange 10 se met en marche et la cuve se vide. Lorsque la cuve 2 est vide la pompe de vidange s'arrête.For pre-washing, 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. When the water in tank 4 is completely replaced, 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.

Pour le lavage à chaud, l'électrovanne 21 s'ouvre et alimente la cuve 2. Pendant ce temps, le moulinet 9 tourne toujours. La résistance 5 du bac est débranchée et celle 7 de la cuve est branchée. Lorsque la cuve 2 est pleine, les électrovannes 15 et 21 se ferment. Lorsque la température de lavage désirée est atteinte, la résistance 7 de la cuve 2 est débranchée et celle 5 du bac 4 est branchée. Le produit de lavage est introduit dans la cuve. Le moulinet 9 continue à tourner quelques minutes pour assurer le lavage à chaud de la vaisselle. Pendant ce temps, la résistance 5 chauffe l'eau du bac 4 à la température désirée pour le rinçage. Le lavage dure environ 8 minutes. Alors la pompe de vidange 10 se met en marche et vide la cuve 2, puis elle s'arrête.For hot washing, 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.

Pour le pré-rinçage, les électrovannes 15 et 21 s'ouvrent pour laisser entrer une certaine quantité d'eau, puis se ferment. Le moulinet 9 tourne toujours pour assurer le pré-rinçage qui dure quelques dizaines de secondes. Alors la pompe 10 se met en marche, vide la cuve puis s'arrête.For pre-rinsing, 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.

Pour le rinçage à chaud, la résistance 5 du bac est débranchée, et les électrovannes 15 et 22 sont ouvertes. L'eau du bac est renouvelée et l'eau très chaude qui était contenue dans le bac 4 coule dans la cuve 2. Le . produit de rinçage est introduit dans la cuve et les électrovannes 15 et 22 se ferment. Le moulinet 9 tourne toujours et assure le rinçage à chaud pendant une minute et demie environ. Le groupe moto-pompe 8 s'arrête alors et la pompe de vidange 10 se met en marche et vide la cuve 2.For hot rinsing, 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.

Pour la régénération de la résine, les électrovannes 12 et 21 s'ouvrent pendant quelques secondes puis se ferment. La pompe de vidange 10 s'arrête une fois la cuve vidée.For the regeneration of the resin, 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.

Pour le séchage, la résistance 7 de la cuve est branchée, elle chauffe la cuve pendant environ une minute et demie, puis est débranchée. A la fin du séchage, le programme s'arrête.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.

On peut remarquer que le programme de la machine comprend les étapes suivantes : un rinçage préalable de la cuve, un pré-lavage, un lavage, un pré-rinçage, un rinçage, une régénération de la résine, et un séchage à chaud. L'ensemble de ces opérations dure environ 15 minutes Durant ce cycle, les deux résistances 5 et 7 ne sont jamais branchées simultanément pour diminuer la consommation d'énergie électrique. La résistance 5 du bac est branchée pendant 7 minutes et demie environ, dont 1 minute et demie pendant le pré-lavage à froid et 6 minutes pendant le lavage. La résistance 7 est branchée pendant 4 minutes environ, dont 2 minutes et demie au début du lavage et 1 minute et demie pendant le séchage.It can be noted that 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.

La disposition du bac 4 est une caractéristique essentielle de la machine à laver la vaisselle selon l'invention Ce bac permet en effet de chauffer l'eau de rinçage pendant la phase de pré-lavage et pendant une partie de la phase de lavage de la machine, et ainsi de raccourcir la durée du cycle complet.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.

Au lieu de laisser de l'eau dans le bac 4, en fin de cycle,on peut procéder à son vidage complet au début de la phase de rinçage à chaud, par soulèvement du tube 6, sans ouverture de l'électrovanne 22. En conséquence, au début de la phase de pré-lavage, il suffit de laisser couler l'eau un peu plus longtemps dans le bac 4 pour assurer, par débordement, l'alimentation en-eau de la cuve 2.Instead of leaving water in tank 4, at the end of the cycle, it can be emptied completely at the start of the hot rinsing phase, by lifting of the tube 6, without opening of the solenoid valve 22. Consequently, at the start of the pre-washing phase, it suffices to let the water run a little longer in the tank 4 to ensure, by overflow, the water supply to tank 2.

La machine à laver la vaisselle selon l'invention permet donc sans accroissement de la consommation d'énergie électrique par rapport aux machines connues d'assurer un cycle de lavage complet en 15 minutes environ, pour une vaisselle de 4 ou 5 couverts.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.
