  • Toy washing machine
    Patent number: 6582276
    Abstract: A toy washing machine has a safety function to prevent the release of water and the like. The safety function locks the door of the toy washing machine when the machine is filled with water. As water is poured into the machine, it flows to a container positioned below an internal drum cabin. The container has a float that rises as the container fills with water. The rising of the float activates a lever device that is connected to a pin. The pin locks the door and prevents the door from opening when water is within the machine. The door of the machine has a seal made of heterotypic silicon rubber that prevents leakage.
