Description

LL'invention est relative à un lave-linge.The invention relates to a washing machine.

Une machine de ce genre comporte habituellement un tambour perforé contenant le linge tournant à l'intérieur d'une cuve destinée à recevoir l'eau de lavage ou rinçage, ou l'eau expulsée du linge lors de l'essorage. Une résistance chauffante est disposée au fond de la cuve pour porter l'eau de lavage à une température choisie : 30°C, 40°C... 90°C, etc.A machine of this kind usually comprises a perforated drum containing the laundry rotating inside a tank intended to receive the washing or rinsing water, or the water expelled from the laundry during spinning. A heating resistor is placed at the bottom of the tank to bring the washing water to a chosen temperature: 30 ° C, 40 ° C ... 90 ° C, etc.

Un dispositif de commande assure le fonctionnement entièrement automatique du lave-linge (voir FR-A-1 555 955). A cet effet ce dernier comprend un programmateur le plus souvent du type électromécanique, c'est-à-dire comprenant un moteur électrique (appelé "micromoteur" pour ne pas le confondre avec le moteur d'entraînement du tambour) qui entraîne des cames agissant sur l'état d'interrupteurs ou contacts câblés avec les divers organes de la machine : électrovanne, moteur, micromoteur, pompe de vidange, résistance chauffante, etc. Un tel programmateur électromécanique peut être associé à un circuit de contrôle de la vitesse de rotation du moteur d'entraînement du tambour, notamment lors des essorages qui peuvent provoquer, du fait de la vitesse élevée de rotation du tambour, des vibrations dangereuses pour la machine. Un tel circuit agit par exemple sur un interrupteur commandé, de préférence à état solide tel qu'un triac, en série avec le moteur d'entraînement du tambour afin de contrôler la phase de conduction de cet interrupteur à chaque période du signal alternatif d'alimentation, la durée de conduction de l'interrupteur statique étant, à chaque période, fonction de la vitesse désirée.A control device ensures the fully automatic operation of the washing machine (see FR-A-1 555 955). For this purpose the latter includes a programmer most often of the electromechanical type, that is to say comprising an electric motor (called "micromotor" so as not to be confused with the drive motor of the drum) which drives cams acting on the state of switches or wired contacts with the various parts of the machine: solenoid valve, motor, micromotor, drain pump, heating resistor, etc. Such an electromechanical programmer can be associated with a circuit for controlling the speed of rotation of the drum drive motor, in particular during wringing which can cause, due to the high speed of rotation of the drum, vibrations dangerous for the machine. . Such a circuit acts for example on a controlled switch, preferably in solid state such as a triac, in series with the drum drive motor in order to control the conduction phase of this switch at each period of the alternating signal of power supply, the conduction time of the static switch being, in each period, a function of the desired speed.

Un interrupteur de contrôle de température est disposé généralement en série avec la résistance de chauffage de l'eau ; celui-ci est ouvert quand la température désirée est atteinte. Un tel interrupteur de contrôle de température est jusqu'à présent soit un thermostat électromécanique à bulbe, soit un thermostat électronique. Un thermostat électromécanique à bulbe constitue un ensemble mécanique d'une réalisation délicate, donc onéreuse. De plus, à un tel thermostat à bulbe on associe souvent un système de cames - faisant partie du programmateur électromécanique -à avance rapide pour passer à l'étape suivante du programme d'exécution de la machine dès que la température désirée est atteinte, ce qui complique encore la réalisation du programmateur.A temperature control switch is generally arranged in series with the water heating resistor; it is opened when the desired temperature is reached. Up to now, such a temperature control switch has been either an electromechanical bulb thermostat or an electronic thermostat. An electromechanical bulb thermostat constitutes a mechanical assembly of a delicate and therefore expensive construction. In addition, such a bulb thermostat is often associated with a cam system - part of the electromechanical programmer - fast forward to go to the next step of the machine execution program as soon as the desired temperature is reached, this which further complicates the production of the programmer.

Un thermostat dit électronique comporte un détecteur à thermistance ou analogue, un interrupteur ou relais de puissance en série avec la résistance chauffante, et un circuit interface pour commander cet interrupteur ou relais en fonction du signal fourni par la thermistance ou analogue. Un tel ensemble est d'un prix élevé.A so-called electronic thermostat comprises a thermistor or similar detector, a power switch or relay in series with the heating resistor, and an interface circuit for controlling this switch or relay as a function of the signal supplied by the thermistor or the like. Such a set is of a high price.

L'invention remédie aux inconvénients mentionnés ci-dessus.The invention overcomes the drawbacks mentioned above.

Le lave-linge selon l'invention comporte un élément de chauffage de l'eau alimenté en énergie en fonction de l'état, ouvert ou fermé d'un interrupteur d'un programmateur électromécanique comprenant des cames entrainées par un micromoteur électrique et des moyens de contrôle de la température pour interrompre l'alimentation de l'élément chauffant quand une température désirée est atteinte. Il est caractérisé en ce que le micromoteur est en série avec un interrupteur statique dont l'état de conduction dépend du signal de sortie d'un circuit de commande, tel qu'un microprocesseur, recevant, d'une part, un signal d'un capteur de la température de l'eau, et d'autre part, un signal de consigne de température et agissant sur la conduction de l'interrupteur statique pour faire tourner le micromoteur afin d'interrompre l'alimentation de l'élément chauffant quand est atteinte la température de consigne.The washing machine according to the invention comprises a water heating element supplied with energy depending on the state, open or closed of a switch of an electromechanical programmer comprising cams driven by an electric micromotor and means temperature control to interrupt the supply to the heating element when a desired temperature is reached. It is characterized in that the micromotor is in series with a static switch whose conduction state depends on the output signal from a control circuit, such as a microprocessor, receiving, on the one hand, a signal from a water temperature sensor, and on the other hand, a temperature setpoint signal and acting on the conduction of the static switch to rotate the micromotor in order to interrupt the supply of the heating element when the set temperature is reached.

Le circuit de commande contrôle ainsi le micromoteur et n'agit pas directement sur le circuit de puissance (la résistance de chauffage de l'eau), ce qui permet une réalisation relativement peu onéreuse, sans relais de puissance.The control circuit thus controls the micromotor and does not act directly on the power circuit (the water heating resistance), which allows a relatively inexpensive embodiment, without power relay.

Par ailleurs la présence du microprocesseur ne complique pas la réalisation de la machine car ce microprocesseur peut être également utilisé pour commander ou contrôler la vitesse de rotation du moteur d'entraînement du tambour.Furthermore, the presence of the microprocessor does not complicate the production of the machine because this microprocessor can also be used to command or control the speed of rotation of the drum drive motor.

Enfin le programmateur électromécanique ne comporte pas de came à avance rapide.Finally, the electromechanical programmer does not have a fast-forward cam.

D'autres caractéristiques et avantages de l'invention apparaîtront avec la description de certains de ses modes de réalisation, celle-ci étant effectuée en se référant au dessin annexé sur lequel la figure unique représente un programmateur de lave-linge conforme à l'invention.Other characteristics and advantages of the invention will appear with the description of some of its embodiments, this being carried out with reference to the appended drawing in which the single figure represents a washing machine programmer in accordance with the invention .

Dans cet exemple le tambour (non montré) est entraîné en rotation par un moteur électrique (également non montré) du type universel en série avec un triac (non représenté) dont la conduction dépend d'un signal de sortie d'un microprocesseur 10, ce qui permet de contrôler la vitesse de rotation de ce moteur.In this example, the drum (not shown) is rotated by an electric motor (also not shown) of the universal type in series with a triac (not shown), the conduction of which depends on an output signal from a microprocessor 10, which allows to control the rotation speed of this motor.

On met à profit la présence du microprocesseur de contrôle de la vitesse du moteur d'entraînement du tambour pour commander, de façon simple, l'alimentation de la résistance 11 de chauffage de l'eau dans la cuve du lave-linge.The presence of the microprocessor for controlling the speed of the drum drive motor is used to control, in a simple manner, the supply of the resistor 11 for heating the water in the tank of the washing machine.

A cet effet le microprocesseur 10 comporte des entrées 101 et 102 pour l'introduction du signal d'un capteur de température 12 tel qu'une thermistance, et des entrées 10s et 104 recevant le signal fourni par un moyen de consigne de température 13 tel qu'un potentiomètre.To this end, the microprocessor 10 has inputs 10 1 and 10 2 for the introduction of the signal from a temperature sensor 12 such as a thermistor, and inputs 10s and 10 4 receiving the signal supplied by a setpoint means of temperature 13 such as a potentiometer.

Une sortie 10s du microprocesseur 10 est reliée à la gâchette 15 d'un triac 14 dont une borne est reliée directement à une première borne 16 sur laquelle est appliqué le signal d'alimentation en courant alternatif et dont l'autre borne est connectée à une extrémité 171 d'un interrupteur 17 dont la seconde extrémité 172 est reliée à une première borne 181 d'un micromoteur 18 d'entraînement des cames (non représentées) d'un programmateur électromécanique. La seconde borne 182 du micromoteur 18 est reliée à la seconde borne 19 d'alimentation en courant alternatif.An output 10s of the microprocessor 10 is connected to the trigger 15 of a triac 14, one terminal of which is connected directly to a first terminal 16 to which the AC power supply signal is applied and the other terminal of which is connected to a end 17 1 of a switch 17, the second end 17 2 of which is connected to a first terminal 18 1 of a micromotor 18 for driving the cams (not shown) of an electromechanical programmer. The second terminal 18 2 of the micromotor 18 is connected to the second terminal 19 for supplying alternating current.

La borne 181 du micromoteur 18 ainsi que la borne 172 de l'interrupteur 17 sont connectées à une borne 201 d'un interrupteur 20 qui comme, l'interrupteur 17, fait partie du programmateur électromécanique. La seconde borne 202 de l'interrupteur 20 est reliée directement à la borne 16 d'alimentation. La position des interrupteurs 17 et 20 dépend de la position de cames entraînées par le micromoteur 18.Terminal 18 1 of micromotor 18 and terminal 17 2 of switch 17 are connected to terminal 20 1 of switch 20 which, like switch 17, is part of the electromechanical programmer. The second terminal 20 2 of the switch 20 is connected di directly to terminal 16 supply. The position of the switches 17 and 20 depends on the position of the cams driven by the micromotor 18.

La résistance 11 de chauffage de l'eau est, par ailleurs, en série avec un autre interrupteur 21 du programmateur électromécanique ainsi qu'avec un pressostat 22 qui est un interrupteur fermé seulement lorsque le niveau de l'eau dans la cuve dépasse une hauteur prédéterminée. L'ensemble en série de la résistance 11 et des interrupteurs 21 et 22 est disposé entre les bornes 16 et 19.The resistor 11 for heating the water is, moreover, in series with another switch 21 of the electromechanical programmer as well as with a pressure switch 22 which is a switch closed only when the level of water in the tank exceeds a height predetermined. The series assembly of the resistor 11 and of the switches 21 and 22 is disposed between the terminals 16 and 19.

Le fonctionnement est le suivant :The operation is as follows:

Lors d'une phase de lavage proprement dit et quand le niveau de l'eau dans la cuve est suffisant les interrupteurs 21 et 22 sont fermés ce qui met sous tension la résistance 11 de chauffage de l'eau. A ce moment l'interrupteur 17 est fermé et l'interrupteur 20 est ouvert. Le triac 14 reste bloqué tant que la température de l'eau n'a pas atteint la valeur de consigne fixée par le potentiomètre 13. Le microprocesseur 10 compare les signaux fournis par la thermistance 12 et par le potentiomètre 13 et quand ces signaux sont égaux un signal est délivré sur la sortie 105 pour rendre le triac 14 conducteur afin de mettre sous tension le micromoteur 18. Autrement dit, pendant les périodes de chauffage de l'eau le micromoteur 18 est à l'arrêt tant que le triac 14 est bloqué ; il en résulte que les interrupteurs 17, 20 et 21 restent dans la position indiquée ci-dessus : l'interrupteur 17 est fermé, l'interrupteur 20 est ouvert et l'interrupteur 21 est fermé. Quand le triac 14 est conducteur, c'est-à-dire quand la température de l'eau est celle désirée, le micromoteur 18 tourne pour entraîner la (les) came(s) qui permet(tent) d'ouvrir l'interrupteur 21, d'ouvrir l'interrupteur 17 et de fermer l'interrupteur 20. Ainsi, quand l'eau est à la température désirée, le micromoteur 18 est alimenté en permanence par l'intermédiaire de l'interrupteur 20 et l'état du triac 14 est sans effet sur l'alimentation de ce micromoteur.During a washing phase proper and when the water level in the tank is sufficient, the switches 21 and 22 are closed, which puts the water heating resistor 11 under tension. At this time the switch 17 is closed and the switch 20 is open. The triac 14 remains blocked as long as the water temperature has not reached the set value set by the potentiometer 13. The microprocessor 10 compares the signals supplied by the thermistor 12 and by the potentiometer 13 and when these signals are equal a signal is delivered on the output 10 5 to make the triac 14 conductive in order to energize the micromotor 18. In other words, during the periods of water heating the micromotor 18 is stopped as long as the triac 14 is blocked; it follows that the switches 17, 20 and 21 remain in the position indicated above: the switch 17 is closed, the switch 20 is open and the switch 21 is closed. When the triac 14 is conductive, that is to say when the water temperature is the desired one, the micromotor 18 rotates to drive the cam (s) which allow (tent) to open the switch 21, to open the switch 17 and to close the switch 20. Thus, when the water is at the desired temperature, the micromotor 18 is continuously supplied by means of the switch 20 and the state of the triac 14 has no effect on the power supply of this micromotor.

En variante, à la place d'un potentiomètre 13 on prévoit un codeur ou sélecteur ou interrupteur à n positions, n étant le nombre de températures de consigne que l'on désire pouvoir choisir.As a variant, instead of a potentiometer 13, an encoder or selector or switch with n positions is provided, n being the number of setpoint temperatures that it is desired to be able to choose.

Par ailleurs, il est bien entendu que le terme "thermistance" englobe tout type de capteur de température.Furthermore, it is understood that the term "thermistor" encompasses any type of temperature sensor.
