  • the thermoelectric element film that outputs the ON signal is determined based on the sheet sensor signal, as shown in FIG.
  • thermoelectric element filter by controlling the current to the thermoelectric element filter by adding driving information and environmental information, it is possible to perform finer control that also takes into account the transfer of heat with the outside of the vehicle. As a result, the air conditioning inside the vehicle is appropriate and comfort is improved. In addition, since wasteful consumption of energy is suppressed, fuel consumption can be improved and drivability can be improved.
  • the thermoelectric element film 19 can also be configured to be operated by a request signal by an artificial operation.

  • thermoelectric element film 19 can heat the glass surface by controlling the direction of current flow. This can be used to perform defrosting and defrosting.
  • Fig. 13 is a block diagram showing an example of this.
  • Controller 20 has information 2 3 from an infrastructure medium that transmits signals wirelessly, such as a mobile phone and a wireless terminal, and ambient temperature sensor information 2 4 Is entered. And The controller 20 is configured to output an operation signal to the thermoelectric element film 19 based on these pieces of information 2 3 and 24 to heat the glass surface.

If a negative determination is made in step S 3 2 because there is no operation request, this routine is temporarily terminated without performing any particular control. On the other hand, if an affirmative determination is made in step S 3 2 due to an operation request, outside air temperature sensor information is read (step S 3 3).
  • thermoelectric element film 19 It is determined whether or not the operation is necessary based on the read outside air temperature sensor information (step S 3 4). That is, it is determined whether it is necessary to energize the thermoelectric element film 19 to operate it as a means for heating the glass surface. Specifically, it is determined whether or not the outside air temperature is equal to or lower than a preset reference temperature.

  • step S 3 4 if a negative determination is made in step S 3 4, there is no possibility of frost adhering because the outside air temperature is high, so this routine is temporarily terminated without performing any particular control. That is, the thermoelectric element film 19 is not energized. On the other hand, if a positive determination is made in step S 3 4, frost may adhere to the glass surface, so an ON signal (actuation signal) is sent to thermoelectric element film 19. Is output (step S 3 5). As a result, the thermoelectric element film 19 functions as a heater, the glass surface is heated, and defrosting is performed.

Defrosting and anti-fogging can be performed. The same applies to mirrors installed in the bathrooms of residences. The same effect can be obtained by applying to the above.
  • the present invention can be applied not only to the window of a vehicle but also to a translucent part of a building window. In that case, indirect cooling can be achieved by passing an electric current through the thermoelectric element film to cool the interior of the room or showcase. In these cases, the information to be used for control can be appropriately determined according to the application.

Abstract

La présente invention concerne un dispositif d'ajustement de la température, prévu pour refroidir et chauffer uniformément toute une région à travers laquelle de la lumière est amenée à passer, permettant ainsi d'ajuster une température au voisinage de la région sur l'une des températures élevées ou faibles. Dans un dispositif d'ajustement des températures, visant à ajuster une température d'au moins un côté de surface des plaques transmettant la lumière (11-17) pour partager un espace prédéterminé, des films de transmission de lumière flexibles (F1-F10), dans lesquels des éléments thermoélectriques de transmission de la lumière pour amener un effet de Peltier sont définis dans leurs régions de transmission de la lumière, sont fixés sur les plaques de transmission de la lumière. Un contrôleur est prévu pour commander un débit de courant électrique des éléments thermoélectriques en réponse à un signal de demande, de sorte que le contrôleur chauffe et refroidisse de manière sélective les plaques de transmission de la lumière.
