System for storing and dispensing liquid cleaning additive for a high-pressure cleaning appliance

摘要

A system for storing and dispensing a liquid cleaning additive for a high-pressure cleaning appliance has a device for storing the cleaning additive and a device for dispensing the cleaning additive in a controlled manner. In order to develop the system such that it is easier to handle, it is proposed that the storage device has an intermediate tank, which is fixedly held on the high-pressure cleaning appliance, and an independently handlable refill container for filling the intermediate tank, it being possible for liquid cleaning additive to be withdrawn in a controlled manner from said intermediate tank by means of the dispensing device, it being possible for the refill container to be secured on the high-pressure cleaning appliance and to be flow-connected to the intermediate tank, cleaning additive flowing automatically out of the refill container into the intermediate tank upon withdrawal of cleaning additive from the intermediate tank, in order to maintain a predetermined liquid level in the intermediate tank. A refill container for such a system and also a high-pressure cleaning appliance having such a system are also proposed.
