Patent ID: 8607693

Claim:
A device for the preparation of a frothy liquid for human consumption, the device comprising: a liquid inlet for human consumption liquid to be frothed, said liquid inlet being connectable to a liquid supply, a jet forming nozzle connected to said liquid inlet and adapted to form a jet of liquid, a liquid flow deflecting member, which liquid flow deflecting member has an inlet, an outlet and a channel which extends between the inlet and the outlet, a collision chamber arranged between the jet forming nozzle and the inlet of the liquid flow deflecting member, one or more air inlets in communication with the collision chamber for the entry of air into said collision chamber, and a discharge passage connected to said collision chamber to discharge the frothed liquid, wherein the jet forming nozzle and the inlet of the liquid flow deflecting member are in communication with the collision chamber and are arranged on opposed locations with respect to the collision chamber, and wherein the jet forming nozzle is adapted to emit a traversing liquid jet that traverses the collision chamber along a path and enters the inlet of the liquid flow deflecting member and passes through the channel thereof to the outlet of said liquid flow deflecting member, and wherein said outlet of the liquid flow deflecting member is arranged in communication with the collision chamber and aimed at the path of the traversing liquid jet between the jet forming nozzle and the inlet of the liquid flow deflecting member, so that in use the liquid jet emerging from the outlet of the flow deflecting member collides with the traversing liquid jet between the jet forming nozzle and the inlet of the liquid flow deflecting member, said collision causing air to be mixed with the liquid thereby generating frothed liquid.
