US Patent 7827831 Detergent flush-in device

A flush-in device is provided for a washing machine and has at least one flushable chamber open at the top. In order that, during flushing, liquid does not easily enter into an outer area of the flush-in device as a result, for example, of leakage and/or water of condensation and in order to simplify the construction of the flush-in device, especially in a sealing area and to reduce assembly expenditure, at least one annular channel at least partially surrounding the upper opening of the flushable chamber is provided and any liquid which has already penetrated into the annular channel can be led away via this channel.
