Description

La présente invention concerne une voiture de train.The present invention relates to a train car.

De manière connue, par exemple de CN 201 151 395 Y , une voiture de train comprend une plateforme desservant au moins un cabinet de toilettes. Pour assurer la ventilation du cabinet de toilettes, et évacuer les mauvaises odeurs, le cabinet de toilettes comprend au moins une entrée d'air, pour faire entrer de l'air de la plateforme à l'intérieur du cabinet de toilettes et une bouche d'extraction d'air, pour évacuer l'air du cabinet de toilettes à l'extérieur du voiture.In known manner, for example from CN 201 151 395 Y , a train car includes a platform serving at least one toilet. To ensure the ventilation of the toilet cabinet, and evacuate bad odors, the toilet cabinet includes at least one air inlet, to bring air from the platform inside the toilet cabinet and an outlet. 'air extraction, to evacuate the air from the toilet cabinet to the outside of the car.

On génère ainsi un courant d'air entre l'entrée d'air et la bouche d'extraction, ce qui permet, en plus de l'évacuation des mauvaises odeurs, de conserver la température du cabinet de toilettes à un niveau proche de celui de la plateforme, laquelle est souvent climatisée.An air current is thus generated between the air inlet and the extraction outlet, which allows, in addition to the evacuation of bad odors, to keep the temperature of the toilet cabinet at a level close to that. of the platform, which is often air-conditioned.

De manière connue en soi, lorsqu'un train passe sous un tunnel, on ferme toutes les ouvertures du voiture communiquant avec l'extérieur pour éviter la propagation d'ondes de pression désagréables pour les oreilles des passagers. En d'autres termes, le train est complètement fermé et étanche lorsqu'il passe sous un tunnel. Il n'y a alors plus d'extraction d'air dans le cabinet de toilettes.In a manner known per se, when a train passes under a tunnel, all the openings of the car communicating with the outside are closed to prevent the propagation of pressure waves which are unpleasant for the ears of the passengers. In other words, the train is completely closed and watertight when it goes through a tunnel. There is then no more air extraction in the toilet.

Cela peut poser des problèmes en période de forte chaleur sur un trajet comportant une succession de tunnels. Effectivement, à cause de l'absence de ventilation à l'intérieur du cabinet de toilettes lorsque le train passe sous un tunnel, la température à l'intérieur du cabinet de toilettes grimpe, ce qui peut conduire à des malaises, notamment en présence de personnes âgées.This can cause problems during periods of strong heat on a route comprising a succession of tunnels. Indeed, because of the lack of ventilation inside the toilet cubicle when the train passes through a tunnel, the temperature inside the toilet cubicle rises, which can lead to discomfort, especially in the presence of the elderly.

Pour pallier ces inconvénients, on pourrait envisager d'installer un système de climatisation dans le cabinet de toilettes. Cela reviendrait à insuffler de l'air froid dans le cabinet de toilettes. Toutefois, lorsque le train passe sous un tunnel et que la bouche d'excitation d'air est fermée, insuffler de l'air froid à l'intérieur du cabinet de toilettes entrainerait une augmentation de pression et des fuites d'air vers la plateforme, avec potentiellement des nuisances odorantes pour les passagers.To overcome these drawbacks, one could consider installing an air conditioning system in the bathroom. It would be like blowing cold air into the toilet. However, when the train passes through a tunnel and the air excitation port is closed, blowing cold air inside the toilet cabinet will cause pressure build-up and air leaks to the platform. , potentially with odor nuisance for passengers.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention, en proposant une voiture dans lequel le cabinet de toilettes peut être refroidi même en l'absence de ventilation, et sans engendrer de fuites d'air en direction de la plateforme.It is these drawbacks that the invention more particularly intends to remedy, by proposing a car in which the toilet cabinet can be cooled even in the absence of ventilation, and without causing air leaks in the direction of the platform. .

A cet effet l'invention concerne une voiture de train, un train et une méthode de contrôle de la température conformes aux revendications annexées.To this end, the invention relates to a train car, a train and a temperature control method according to the appended claims.

Grâce à l'invention, le module Peltier produit, par convection avec l'air ambiant à l'intérieur du cabinet de toilettes, un courant d'air froid qui se dirige sous son propre poids en direction du sol du cabinet de toilettes. On diminue alors la température à l'intérieur du cabinet de toilettes et on crée en outre un léger brassage de l'air par convection. L'avantage à utiliser un module Peltier est que celui-ci peut fonctionner sans extraction d'air, c'est-à-dire même lorsque le train passe sous un tunnel et que celui-ci ne modifie pas la pression à l'intérieur du cabinet de toilettes. Il n'y a donc pas de risques de provoquer des fuites d'air vers la plateforme.Thanks to the invention, the Peltier module produces, by convection with the ambient air inside the toilet cabinet, a current of cold air which is directed under its own weight towards the floor of the toilet cabinet. The temperature inside the toilet cabinet is then reduced and a slight air circulation is also created by convection. The advantage of using a Peltier module is that it can operate without air extraction, that is to say even when the train passes through a tunnel and the latter does not modify the pressure inside. from the toilet. There is therefore no risk of causing air leaks to the platform.

L'invention est d'autres avantages de celle-ci apparaitront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'une voiture conforme à son principe, donnée uniquement à titre d'exemple et faite en référence à la figure 1 représentant un schéma d'un cabinet de toilettes appartenant à une voiture conforme à l'invention.The invention and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a car in accordance with its principle, given only by way of example and made by reference. to the figure 1 showing a diagram of a toilet belonging to a car according to the invention.

La figure 1 montre un cabinet de toilettes 2 faisant partie d'une voiture de train (non représenté). Typiquement, le cabinet de toilettes est desservi par ce qu'on appelle une plateforme d'accès voyageurs (non représentée), correspondant à l'espace entre les voitures qui donne accès au quai grâce aux portes d'accès voyageurs. Le train peut être un train à grande vitesse ou au contraire un train de voyageurs standard.The figure 1 shows a toilet 2 forming part of a train carriage (not shown). Typically, the toilet is served by what is called a passenger access platform (not shown), corresponding to the space between the cars which gives access to the platform through the passenger access doors. The train can be a high speed train or on the contrary a standard passenger train.

Le cabinet de toilettes 2 comprenant au moins une entrée d'air 4, pour faire entrer de l'air de la plateforme à l'intérieur du cabinet de toilettes et une bouche d'extraction d'air 6, pour évacuer l'air du cabinet de toilettes 2 à l'extérieur du voiture. Dans l'exemple, l'entrée d'air 4 est une grille intégrée à une porte 8 du cabinet de toilettes et la bouche d'extraction d'air 6 est intégrée au plafond 10 du cabinet de toilettes. En variante, on pourrait imaginer que la bouche d'extraction d'air 6 soit intégrée à une paroi du cabinet de toilettes, de préférence en partie haute, à proximité du plafond 10.The toilet cabinet 2 comprising at least one air inlet 4, to bring air from the platform inside the toilet cabinet and an air extraction outlet 6, to evacuate the air from the toilet. 2 toilets outside the car. In the example, the air inlet 4 is a grille integrated into a door 8 of the toilet cabinet and the air extraction outlet 6 is integrated into the ceiling 10 of the toilet cabinet. As a variant, one could imagine that the air extraction outlet 6 is integrated into a wall of the toilet cabinet, preferably in the upper part, near the ceiling 10.

Typiquement, la bouche d'extraction d'air 6 communique avec une gaine d'extraction d'air 7 ouverte sur l'extérieur du voiture. Dans l'exemple, la gaine d'extraction d'air 7 s'étend à partir du plafond 10 du cabinet de toilettes.Typically, the air extraction mouth 6 communicates with an air extraction duct 7 open to the outside of the car. In the example, the air extraction duct 7 extends from the ceiling 10 of the toilet cabinet.

Le cabinet de toilettes est équipé d'un système de refroidissement, qui ne comprend pas de système de climatisation avec insufflation d'air froid. En effet, le système de refroidissement comprend un module Peltier 12. Typiquement, le module Peltier 12 est intégré au plafond 10 du cabinet de toilettes 2, c'est-à-dire logé dans le faux-plafond du cabinet de toilettes. En variante, on pourrait imaginer que le module Peltier 12 soit intégré à une paroi latérale du cabinet de toilettes 2, de préférence en partie haute, à proximité du plafond 10.The toilet room is equipped with a cooling system, which does not include an air conditioning system with cold air blowing. Indeed, the cooling system comprises a Peltier module 12. Typically, the Peltier module 12 is integrated into the ceiling 10 of the toilet cabinet 2, that is to say housed in the false ceiling of the toilet cabinet. As a variant, one could imagine that the Peltier module 12 is integrated into a side wall of the toilet cabinet 2, preferably in the upper part, near the ceiling 10.

Le module Peltier 12 comprend une surface froide 120 orientée vers l'intérieur du cabinet de toilettes et une surface chaude 122 orientée de manière opposée à la surface froide 120, c'est-à-dire vers l'extérieur du cabinet de toilettes 2.The Peltier module 12 comprises a cold surface 120 oriented towards the interior of the toilet cabinet and a hot surface 122 oriented in a manner opposite to the cold surface 120, that is to say towards the outside of the toilet cabinet 2.

Avantageusement, le système de refroidissement comprend un dispositif thermique 14 pour évacuer la chaleur de la surface chaude 122 du module Peltier 12. Effectivement, pour être efficace, la surface chaude 122 du module Peltier 12 doit être refroidie. Cela signifie que la chaleur de la surface chaude 122 doit être évacuée.Advantageously, the cooling system comprises a thermal device 14 for removing heat from the hot surface 122 of the Peltier module 12. Indeed, to be effective, the hot surface 122 of the Peltier module 12 must be cooled. This means that the heat of the hot surface 122 must be removed.

Dans l'exemple, le dispositif thermique 14 comprend au moins une ailette. Cette ailette permet par définition d'augmenter la surface de contact avec l'air pour augmenter les échanges convectifs, et donc le transfert de chaleur. En variante, le dispositif thermique 14 pourrait également comprendre, en remplacement ou en complément, un caloduc.In the example, the thermal device 14 comprises at least one fin. By definition, this fin makes it possible to increase the contact surface with the air in order to increase convective exchanges, and therefore heat transfer. As a variant, the thermal device 14 could also comprise, in replacement or in addition, a heat pipe.

Avantageusement, le dispositif thermique 14, quel qu'il soit, est disposé de façon à transférer la chaleur de la surface chaude 122 du module Peltier 12 au volume d'air contenu à l'intérieur de la gaine d'extraction d'air 7. Comme la gaine d'extraction d'air 7 s'étend à partir du plafond 10, le volume d'air chaud dans la gaine 7 ne s'échappe pas à l'intérieur du cabinet de toilettes 2.Advantageously, the thermal device 14, whatever it is, is arranged so as to transfer the heat from the hot surface 122 of the Peltier module 12 to the volume of air contained inside the air extraction duct 7. As the air extraction duct 7 extends from the ceiling 10, the volume of hot air in the duct 7 does not escape inside the toilet cabinet 2.

Le fonctionnement du système de refroidissement est le suivant. Tant que le train n'est pas dans un tunnel, la gaine d'extraction 7 est ouverte et on a la présence d'un courant d'air entre l'entrée d'air 4 et la bouche d'extraction d'air 6, comme représenté par les flèches F1 à la figure 1. Ce courant d'air permet, d'une part, d'évacuer les mauvaises odeurs à l'extérieur du voiture et, d'autre part, de conserver la température du cabinet de toilettes 2 à un niveau proche de celui de la plateforme, laquelle est de préférence climatisée. Lorsque le train passe sous un tunnel, en revanche, la gaine d'extraction d'air 7 se ferme et il n'y a plus de ventilation à l'intérieur du cabinet de toilettes 2. On active alors le module Peltier 12 pour éviter d'avoir une température trop élevée à l'intérieur du cabinet de toilettes.The operation of the cooling system is as follows. As long as the train is not in a tunnel, the extraction duct 7 is open and there is an air current between the air inlet 4 and the air extraction outlet 6 , as represented by the arrows F1 at the figure 1 . This air current allows, on the one hand, to evacuate bad smells outside the car and, on the other hand, to keep the temperature of the toilet cabinet 2 at a level close to that of the platform, which is preferably air conditioned. When the train passes under a tunnel, on the other hand, the air extraction duct 7 closes and there is no more ventilation inside the toilet cabinet 2. The Peltier module 12 is then activated to avoid to have too high a temperature inside the toilet.

Typiquement, le voiture est équipé d'un mécanisme (non représenté) pour arrêter automatiquement l'extraction d'air à l'intérieur du cabinet de toilettes 2 lorsque le train passe sous un tunnel. Ce type de mécanisme est connu en soi, c'est pourquoi il n'est pas décrit plus avant.Typically, the car is equipped with a mechanism (not shown) to automatically stop the extraction of air inside the toilet cabinet 2 when the train passes under a tunnel. This type of mechanism is known per se, which is why it is not described further.

Eventuellement, le module Peltier 12 peut être activé aussi lorsque la simple ventilation naturelle ne suffit pas à refroidir le cabinet de toilettes 2 qui, on le rappelle, n'est pas climatisé. Cela peut arriver en période de grosse chaleur ou plus simplement dans les pays chauds. Typiquement, on peut envisager d'activer le module Peltier uniquement lorsque la température mesurée est supérieure à une première valeur seuil, par exemple égale à 25°C. Pour cela, il convient de mesurer en permanence la température à l'intérieur du cabinet de toilettes 2.Optionally, the Peltier module 12 can also be activated when simple natural ventilation is not sufficient to cool the toilet cabinet 2 which, it will be recalled, is not air-conditioned. This can happen in periods of great heat or more simply in hot countries. Typically, it is possible to envisage activating the Peltier module only when the measured temperature is greater than a first threshold value, for example equal to 25 ° C. For this, it is necessary to continuously measure the temperature inside the toilet cabinet 2.

Avantageusement, le cabinet de toilettes 2 est équipé d'un capteur de température (non représenté) et d'une unité électronique (non représentée) de commande du module Peltier 12, laquelle est capable de collecter la température mesurée par le capteur et de commander l'activation du module Peltier 12 en fonction de la température mesurée, notamment d'activer le module Peltier 12 uniquement lorsque la température mesurée est supérieure à une valeur seuil, par exemple de l'ordre de 25°C. Ce type de régulation permet de faire fonctionner le module Peltier uniquement lorsque nécessaire et donc de faire des économies d'énergie.Advantageously, the toilet cabinet 2 is equipped with a temperature sensor (not shown) and an electronic unit (not shown) for controlling the Peltier module 12, which is capable of collecting the temperature measured by the sensor and of controlling activating the Peltier module 12 as a function of the measured temperature, in particular activating the Peltier module 12 only when the measured temperature is greater than a threshold value, for example of the order of 25 ° C. This type of regulation makes it possible to operate the Peltier module only when necessary and therefore to save energy.

Le module Peltier 12 produit, par convection avec l'air ambiant à l'intérieur du cabinet de toilettes 2, un courant d'air froid F2 qui se dirige sous son propre poids en direction du sol du cabinet de toilettes. On diminue alors la température à l'intérieur du cabinet de toilettes 2 et on crée en outre un léger brassage de l'air par convection. Le module Peltier 12 peut fonctionner sans extraction d'air, c'est-à-dire même lorsque le train passe sous un tunnel et son fonctionnement ne modifie pas la pression à l'intérieur du cabinet de toilettes. Il n'y a donc pas de risques de provoquer des fuites d'air vers la plateforme.The Peltier module 12 produces, by convection with the ambient air inside the toilet cabinet 2, a stream of cold air F2 which is directed under its own weight towards the floor of the toilet cabinet. The temperature inside the toilet cabinet 2 is then reduced and, in addition, a slight stirring of the air is created by convection. The Peltier module 12 can operate without air extraction, that is to say even when the train passes through a tunnel and its operation does not modify the pressure inside the toilet cabinet. There is therefore no risk of causing air leaks to the platform.

La méthode utilisée pour contrôler la température à l'intérieur du cabinet de toilettes 2 comprend donc au moins deux étapes consistant à :

  1. a) mesurer la température à l'intérieur du cabinet de toilettes 2,
  2. b) activer le module Peltier 12 uniquement lorsque la température mesurée est supérieure à une première valeur seuil et/ou lorsque le voiture de train passe sous un tunnel.
The method used to control the temperature inside the toilet cabinet 2 therefore comprises at least two steps consisting of:
  1. a) measure the temperature inside the toilet cabinet 2,
  2. b) activate the Peltier module 12 only when the measured temperature is greater than a first threshold value and / or when the train car passes through a tunnel.

Avantageusement, on peut également envisager de désactiver le module Peltier 12 lorsque la température mesurée chute en dessous d'une seconde valeur seuil, inférieure à la première valeur seuil. Typiquement, cette seconde valeur seuil peut être de l'ordre de 15°C. On évite alors qu'il fasse trop froid dans le cabinet de toilettes 2.Advantageously, it is also possible to envisage deactivating the Peltier module 12 when the measured temperature drops below a second threshold value, lower than the first threshold value. Typically, this second threshold value can be of the order of 15 ° C. This prevents it from getting too cold in the bathroom 2.

Les caractéristiques du mode de réalisation et des différentes variantes peuvent être combinées entre elles pour générer de nouveaux modes de réalisation de l'invention dans le domaine défini par la portée des revendications jointes.The characteristics of the embodiment and of the different variants can be combined with one another to generate new embodiments of the invention in the field defined by the scope of the appended claims.
