Abstract

A heating procedure for a washer/drier consists of heating the washing during the wash and/or rinse cycle by injecting hot air, steam or water produced by the drier heater (9). The machine has a single heater unit, located in its drying circuit (5) and fed with electricity during the wash and/or rinse and drying cycles. The single air intake (6) for the heater unit is situated above the water level in the machine's drum (3) to allow the water to be heated by means of hot air during the wash and/or rinse cycles. The drying circuit outlet duct (7) ends at the axis of the drum, and the water recirculation circuit is connected to the drying circuit upstream of the heater.

Description

La présente invention se rapporte à un procédé et à un dispositif de chauffage pour machine à laver séchante.The present invention relates to a method and a device heater for washer-dryer.

Certains types de machine à laver le linge séchantes comportent deux éléments chauffants, un pour chauffer les bains de lavage, et un pour chauffer l'air de séchage. Une telle solution est onéreuse du fait du doublement des éléments chauffants. D'autres types de machines à laver séchantes comportent un seul élément de chauffage pour assurer les deux fonctions précitées. Ce seul élément chauffant est disposé au fond de la cuve de la machine, mais on a constaté que son rendement en fonction séchage est très faible et que sa mise au point est difficile à cause des températures élevées produites au fond de la cuve en fonction séchage.Some types of washer dryers include two heating elements, one for heating the washing baths, and one for heat the drying air. Such a solution is expensive because of the doubling of the heating elements. Other types of washing machines dryers have a single heating element to ensure both aforementioned functions. This single heating element is placed at the bottom of the machine tank, but it was found that its performance as a function drying is very weak and its development is difficult because of the high temperatures produced at the bottom of the tank in drying function.

La présente invention a pour objet un procédé de chauffage pour machine à laver séchante qui permette de réduire le coût de la machine, d'en augmenter la fiabilité liée aux composants critiques, à la température élevée du fond de la cuve et à la régulation de celle-ci, et d'en améliorer le rendement par un chauffage plus rapide jusqu'à la température désirée du linge mouillé.The subject of the present invention is a heating method for drying machine which reduces the cost of the machine, increase reliability linked to critical components, temperature the bottom of the tank and to regulate it, and improve the performance by faster heating to the desired temperature of the wet laundry.

La présente invention a également pour objet une machine à laver séchante pour la mise en oeuvre de ce procédé.The present invention also relates to a washing machine drying for the implementation of this process.

Le procédé de chauffage conforme à l'invention consiste à chauffer le linge à laver et/ou à rincer en injectant de l'air chaud produit par le dispositif de séchage de la machine dans la masse de linge mouillé.The heating method according to the invention consists in heat the laundry to be washed and / or rinsed by injecting hot air produced by the device for drying the machine in the mass of wet laundry.

Le dispositif de chauffage d'une machine à laver séchante conforme à l'invention comporte un unique bloc de chauffage disposé dans le circuit de séchage de la machine, qui est alimenté en énergie en phases de lavage et/ou rinçage et en phase de séchage.The heater of a washer-dryer according to the invention comprises a single heating block arranged in the drying circuit of the machine, which is supplied with energy in phases washing and / or rinsing and drying phase.

La présente invention sera mieux comprise à la lecture de la description détaillée d'un mode de réalisation, pris à titre d'exemple non limitatif et illustré par le dessin annexé, sur lequel :

  • la figure 1 est une vue simplifiée en coupe d'une machine conforme à l'invention, en phase de lavage de linge, et
  • la figure 2 est une vue similaire à celle de la figure 1, mais en phase de séchage de linge.
The present invention will be better understood on reading the detailed description of an embodiment, taken by way of nonlimiting example and illustrated by the appended drawing, in which:
  • FIG. 1 is a simplified sectional view of a machine according to the invention, in the washing phase, and
  • Figure 2 is a view similar to that of Figure 1, but in the drying phase of laundry.

La machine lavante-séchante 1 représentée sur le dessin comporte essentiellement une carrosserie 2 renfermant une cuve 3 à l'intérieur de laquelle tourne un tambour 4. Un circuit de séchage 5 (chauffage et propulsion d'air) a son entrée d'air 6 reliée à la partie supérieure de la cuve 3, au-dessus du niveau d'eau de la cuve, et son tube de sortie 7 est relié au tambour 4. De préférence, l'extrémité de ce tube 7 est coaxiale à l'axe du tambour 4. En variante, l'extrémité du tube 7 peut déboucher au fond de la cuve 3. Ce circuit de séchage 5 comporte, de façon connue en soi, un ventilateur 8 et un bloc 9 de chauffage d'air. Les autres éléments de la machine, inutiles pour la compréhension de l'invention (moteurs, programmateur, capteur thermique, condenseur, circuit de régulation de température, etc.) n'ont pas été représentés sur le dessin. Une charge de linge 10 a été disposée dans le tambour 4.The washer-dryer 1 shown in the drawing essentially comprises a bodywork 2 containing a tank 3 to the interior of which rotates a drum 4. A drying circuit 5 (heating and air propulsion) has its air inlet 6 connected to the part upper part of the tank 3, above the water level of the tank, and its tube outlet 7 is connected to the drum 4. Preferably, the end of this tube 7 is coaxial with the axis of the drum 4. As a variant, the end of the tube 7 can lead to the bottom of the tank 3. This drying circuit 5 comprises, so known per se, a fan 8 and an air heating block 9. Others elements of the machine, useless for understanding the invention (motors, programmer, thermal sensor, condenser, circuit temperature control, etc.) have not been shown in the drawing. A laundry load 10 has been placed in the drum 4.

Comme représenté en figure 1, une quantité appropriée d'eau de lavage 11 est admise dans la cuve 3. Généralement, le niveau d'eau est nettement en-dessous de l'axe du tambour 4, ce qui fait qu'une partie seulement de la charge de linge 10 trempe dans cette eau, le reste du linge étant seulement mouillé.As shown in Figure 1, an appropriate amount of water from washing 11 is allowed in the tank 3. Generally, the water level is clearly below the axis of the drum 4, which makes that part only laundry load 10 soaks in this water, the rest of the laundry being only wet.

L'air chaud insufflé dans le tambour 4 par le tube 7 est ainsi directement en contact avec le linge mouillé, ce qui fait que l'eau de lavage est chauffée surtout indirectement par le linge. Bien entendu, il est avantageux de n'insuffler l'air chaud dans le tambour que lorsque le linge est complètement mouillé. Il est également bien entendu que ce chauffage peut être mis en oeuvre en phase de rinçage.The hot air blown into the drum 4 through the tube 7 is thus directly in contact with wet laundry, so that the washing water is heated mainly indirectly by the linen. Of course, it is advantageous to only blow hot air into the drum when the laundry is completely wet. It is also understood that this heating can be implemented in the rinsing phase.

Comme représenté en figure 2, en phase de séchage, l'eau de la cuve est évacuée, et l'air chaud est envoyé par le circuit 5 de la même façon qu'en figure 1, c'est-à-dire vers l'axe du tambour 4.As shown in Figure 2, in the drying phase, the water from the tank is evacuated, and hot air is sent through circuit 5 in the same way as in FIG. 1, that is to say towards the axis of the drum 4.

Bien entendu, lors du déroulement des différentes phases de lavage, rinçage et séchage, la température de l'air chaud envoyé par le circuit 5 dans le tambour est régulée à une valeur appropriée à chacune de ces phases.Of course, during the course of the different phases of washing, rinsing and drying, the temperature of the hot air sent by the circuit 5 in the drum is regulated to a value appropriate to each of these phases.

Ainsi, grâce à l'invention, on supprime un élément de chauffage avec son capteur de température et les circuits associés, ce qui permet de réduire le coût de la machine. En outre, on améliore la fiabilité de la machine par la suppression de ces éléments, et on améliore le rendement de la machine en lavage, et éventuellement en rinçage, grâce au fait que la température du linge mouillé, directement chauffé par l'air chaud, augmente plus rapidement que lorsque l'on chauffe directement l'eau de lavage.Thus, thanks to the invention, we remove a heating element with its temperature sensor and associated circuits, which allows reduce the cost of the machine. In addition, the reliability of the machine is improved by removing these elements, and we improve the efficiency of the machine washing, and possibly rinsing, thanks to the fact that the temperature of wet laundry, directly heated by hot air, increases faster than when the wash water is heated directly.

De façon avantageuse, on peut augmenter la puissance de l'élément chauffant 10 par rapport à celle d'un élément chauffant de séchage classique, afin de diminuer le temps de chauffage en phase de lavage.Advantageously, the power of the heating element 10 with respect to that of a drying heating element conventional, in order to reduce the heating time in the washing phase.

De façon avantageuse également, on peut supprimer la volume mort de fond de cuve, puisque l'on n'a plus besoin de prévoir de volume supplémentaire pour y loger l'élément chauffant de l'eau de lavage. On diminue ainsi le volume d'eau nécessaire au lavage, et donc aussi l'énergie de chauffage.Also advantageously, the volume can be eliminated bottom of tank dead, since we no longer need to provide volume extra to house the washing water heating element. We thus decreases the volume of water required for washing, and therefore also the energy of heating.

Selon une variante de l'invention, le circuit 5 peut injecter dans le tambour en phase de lavage et/ou rinçage, en plus de l'air chaud (par exemple alternativement) de la vapeur d'eau ou de l'eau chaude. Pour cela, on fait recirculer l'eau de lavage, ou de rinçage, que l'on envoie dans le circuit de séchage, en amont de l'élément chauffant 9 (circuit de recirculation 12 représenté en traits interrompus sur la seule figure 1).According to a variant of the invention, the circuit 5 can inject into the drum in washing and / or rinsing phase, in addition to hot air (for alternatively) steam or hot water. For that, we recirculate the washing or rinsing water, which we send into the drying circuit, upstream of the heating element 9 (recirculation circuit 12 shown in broken lines in Figure 1 only).
