Abstract

"SISTEMA DE ABERTURA E FECHAMENTO DE PORTA". Um aparelho de mudar estado de porta ajuda um usuário a mover uma porta entre um estado fechado onde a porta (8, 9) é posicionada adjacente a uma estrutura de porta, e um estado aberto. O aparelho de mudar estado de porta inclui um ímã permanente (13, 14) provido sobre a porta, e tendo um campo magnético permanente. Um eletroímã (11, 12) é localizado sobre a estrutura de porta, adjacente ao ímã permanente com a porta em um estado fechado, e é energizável para prover um campo magnético que reforça o campo magnético permanente do imã permanente ou para prover um campo magnético em oposição ao campo magnético permanente do ímã permanente. Um detector de posição de porta detecta o estado aberto ou fechado da porta e uma interface de usuário detecta a presença de um usuário tentando alterar aquele estado. Um controlador (6) recebe entrada do detector de posição de porta e a interface de usuário e energiza o eletroímã (11, 12) para prover um campo magnético reforçado se um usuário está tentando movimentar a porta (8, 9) desde um estado aberto até um estado fechado e provê um campo magnético oposto ao campo magnético permanente do ímã permanente se a porta está fechada e a interface de usuário indica que um usuário está tentando abrir a porta. A invenção é particularmente adaptada para uso em um refrigerador doméstico.
