Definitions

  • the present application relates to clothes drying systems and, in particular, clothes drying systems that control operations based on surrounding temperatures.
  • Combination washing and drying apparatuses include both a washing cycle for washing clothes and a drying cycle for drying clothes.
  • the washing and drying apparatuses may be either open-loop (vented) or closed-loop (condensing).
  • an open-loop washing and drying apparatus the wet air from a drum where the clothes are dried is directed to the environment.
  • a closed-loop washing and drying apparatus the wet air from the drum is directed to a condenser where moisture is removed from the wet air. The drier air is then directed from the condenser back to the drum for the drying operation.
  • open and closed-loop drying systems have advantages. For example, open-loop drying systems vent the wet air to the environment and replace the vented air with drier intake air. This venting of the relatively wet air can reduce drying time compared to a closed-loop drying system. Closed-loop drying systems may be used in locations where a vent is not present or would require major infrastructure changes to allow access to an outside space, such as in some apartment buildings. These closed-loop drying systems can have longer drying times than open-loop drying systems. It would be desirable to allow some controlled venting into a room to relatively quickly remove moist air from the system, which can reduce drying time compared to a closed-loop drying system.

    (iii) un chauffage (24) de changer une quantité de chaleur fournie à l'air s'écoulant à travers le circuit d'air de séchage en fonction du signal provenant du capteur de température,
    caractérisé en ce que la mémoire comporte en outre une logique qui, lorsqu'elle est exécutée par le circuit de traitement, ordonne à la vanne de commande d'air d'évacuation de réduire une quantité d'air chauffé s'écoulant du tambour dans l'environnement en fonction du signal lorsqu'une température détectée est supérieure à une température par défaut et d'augmenter une quantité d'air chauffé s'écoulant du tambour dans l'environnement lorsqu'une température détectée de l'environnement est inférieure à la température par défaut.
  2. Système selon l'une quelconque des revendications précédentes, dans lequel la mémoire comporte une logique qui, lorsqu'elle est exécutée par le circuit de traitement, ordonne à une vanne de commande d'air d'admission (32) de commander une quantité d'air s'écoulant dans le circuit d'air de séchage à partir de l'environnement au niveau d'une localisation en aval du condenseur à un débit d'admission qui est environ égal au débit de sortie auquel la vanne de commande d'évacuation évacue dans l'environnement.
  3. Système selon l'une quelconque des revendications précédentes comprenant en outre une entrée utilisateur (94) qui permet à un utilisateur de fournir une température sélectionnée par l'utilisateur, dans lequel la mémoire comporte une logique qui, lorsqu'elle est exécutée par le circuit de traitement, ordonne à la vanne de commande d'air d'évacuation de réduire une quantité d'air chauffé s'écoulant du tambour dans l'environnement en fonction du signal lorsqu'une température détectée est supérieure à la température sélectionnée par l'utilisateur et d'augmenter une quantité d'air chauffé s'écoulant du tambour dans l'environnement lorsqu'une température détectée est inférieure à la température sélectionnée par l'utilisateur.
  4. Système selon l'une quelconque des revendications précédentes, dans lequel le capteur de température est localisé à l'extérieur de l'appareil.
  5. Système selon l'une quelconque des revendications précédentes comprenant en outre un capteur de proximité (162) qui fournit un signal indiquant une distance du capteur de proximité par rapport à une ou plusieurs parois qui définissent au moins partiellement une limite de l'environnement.
  6. Système selon l'une quelconque des revendications précédentes, dans lequel la mémoire comporte une logique qui, lorsqu'elle est exécutée par le circuit de traitement, commande un débit d'air à travers le condenseur à l'aide de la vanne de commande d'air d'évacuation (28), d'une vanne de commande d'air d'admission (32) et/ou de la soufflante (27).
  7. Système selon l'une quelconque des revendications précédentes comprenant en outre un autre capteur de température (90) au niveau d'une évacuation d'air d'un système de chauffage, ventilation et conditionnement d'air (HVAC) qui fournit un signal indiquant une température au niveau de l'évacuation d'air, la mémoire comporte une logique qui, lorsqu'elle est exécutée par le circuit de traitement, ordonne à la vanne de commande d'air d'évacuation de commander une quantité d'air chauffé s'écoulant du tambour dans l'environnement en fonction du signal provenant de cet autre capteur de température.
  8. Système selon l'une quelconque des revendications précédentes, la mémoire comporte une logique qui, lorsqu'elle est exécutée par le circuit de traitement, ordonne à la vanne de commande d'air de commander une quantité d'air chauffé s'écoulant du tambour dans l'environnement en fonction d'informations météorologiques reçues sur un réseau sans fil pour une zone géographique où l'appareil est localisé.
  9. Procédé de commande du système de séchage de vêtements comprenant le système selon l'une quelconque des revendications 1 à 8, le procédé comprenant :
    l'acheminement d'air à travers le circuit d'air de séchage vers le tambour (16) ;
    l'acheminement d'air chauffé provenant du tambour vers le condenseur (30) ;
    la fourniture d'un signal à l'aide du capteur de température (90) indiquant une température d'un environnement à l'extérieur de l'appareil ; et
    en fonction du signal provenant du capteur de température, un contrôleur (80) ordonnant à au moins l'un parmi :
    (i) la vanne de commande d'air d'évacuation (28) de changer une quantité d'air chauffé s'écoulant du tambour à travers la vanne de commande d'air d'évacuation et dans l'environnement en fonction du signal provenant du capteur de température ;
    (ii) la soufflante (27) de changer un débit d'air s'écoulant à travers le circuit d'air de séchage en fonction du signal provenant du capteur de température ; et
    (iii) le chauffage (24) de changer une quantité de chaleur fournie à l'air s'écoulant à travers le circuit d'air de séchage en fonction du signal provenant du capteur de température,
    dans lequel le procédé comprend une étape consistant à ordonner à la vanne de commande d'air d'évacuation à l'aide du dispositif de commande de réduire une quantité d'air chauffé s'écoulant du tambour dans l'environnement en fonction du signal lorsqu'une température détectée est supérieure à une température par défaut et d'augmenter une quantité d'air chauffé s'écoulant du tambour dans l'environnement lorsqu'une température détectée de l'environnement est inférieure à la température par défaut.
  10. Procédé selon l'une quelconque parmi la revendication 9, dans lequel le procédé comprend en outre le fait d'ordonner à la vanne de commande d'air d'admission de commander une quantité d'air s'écoulant dans le circuit d'air de séchage provenant de l'environnement au niveau d'une localisation en aval du condenseur à un débit d'admission qui est égal à un débit de sortie auquel la vanne de commande d'air d'évacuation évacue de l'air dans l'environnement.
  11. Procédé selon la revendication 9 comprenant en outre le changement de la température par défaut sur une température sélectionnée par l'utilisateur qui est différente de la température par défaut.
