A device (1) comprises an intake duct (11) for taking in milk, an intake duct (15) for taking in a cleaning fluid, a central duct (13) in which both intake ducts (11, 15) are merging, and a pump (31) which is arranged in the central duct (13). Cleaning the device (1) involves filling both the central duct (13) and the milk intake duct (11) with the cleaning fluid. In particular, the pump (31) is a bi-directional pump, wherein filling the central duct (13) with the cleaning fluid is realized by operating the pump (31) in one direction while blocking the milk intake duct (11), and wherein filling the milk intake duct (11) with the cleaning fluid is realized by opening the milk intake duct (11) and operating the pump (31) in a reversed direction, wherein cleaning fluid is displaced from the central duct (13) to the milk intake duct (11).

1. A device suitable for whisking milk, the device comprising: a duct system having a milk intake duct for taking in milk,a cleaning fluid intake duct for taking in a cleaning fluid, anda central duct in which both the milk intake duct and the cleaning fluid intake duct are merging,a first valve cap
1. A device suitable for whisking milk, the device comprising: a duct system having a milk intake duct for taking in milk,a cleaning fluid intake duct for taking in a cleaning fluid, anda central duct in which both the milk intake duct and the cleaning fluid intake duct are merging,a first valve capable of switching between a first and second position where the first position selectively blocks the milk intake duct at a position between a milk reservoir and the central duct and leaves the cleaning fluid intake duct open, and where the second position selectively blocks the cleaning fluid intake duct between a cleaning fluid reservoir and the central duct and leaves the milk intake duct open, anda pump which is arranged in the central duct, and which is a bi-directional pumpan air intake duct for taking in air, which merges in the central duct at the same position as the cleaning fluid intake duct, wherein a portion of the cleaning fluid intake duct and a portion of the air intake duct are joined to one duct, and wherein a single-directional check valve is arranged in this one duct. 2. Device according to claim 1, further comprising a sieve which is arranged at an outlet of the duct system. 3. Device according to claim 1, further comprising an outlet duct which is merging into the central duct the outlet duct merging into the central duct on one side of the pump and the air intake duct and the milk intake duct and the cleaning fluid intake duct merging into the central duct on another side of the pump, and a second valve which is a single direction valve and is positioned in one of the outlet duct or the central duct and is capable of blocking one of the outlet duct and the central duct at a position downstream of the merging of the outlet duct to the central duct while leaving another of these ducts open. 4. Device according to claim 3, further comprising a drip tray for receiving waste fluid, wherein one of the central duct and the outlet duct is arranged for emitting the waste fluid to the drip tray, and wherein a sieve is arranged in another of the central duct and the outlet duct. 5. Device according to claim 1, further comprising heating means which are arranged in the central duct. 6. A method for cleaning a device suitable for whisking milk, the device comprising a duct system having a milk intake duct for taking in milk, a cleaning fluid intake duct for taking in a cleaning fluid, and a central duct into which both the milk intake duct and the cleaning fluid intake duct are merging, a first valve capable of switching between a first and second position where the first position selectively blocks the milk intake duct at a position between a milk reservoir and the central duct and leaves the cleaning fluid intake duct open, and where the second position selectively blocks the cleaning fluid intake duct between a cleaning fluid reservoir and the central duct and leaves the milk intake duct open, and a pump which is arranged in the central duct, and which is a bi-directional pump, the milk intake duct and the cleaning fluid intake duct up to their merging into the central duct defines an intake side of the duct system and the central duct from the merging up to an outlet of the central duct defines an outlet side of the duct system, the method comprising: at a first cleaning stage: i) operating the pump to perform a pumping action in a first direction from an intake side of the duct system to an outlet side of the duct system,ii) placing the first valve at a first position for blocking the milk intake duct,at a second cleaning stage: i) operating the pump in a reversed direction from an intake side of the duct system to an outlet side of the duct system,ii) placing the first valve at a second position for allowing the cleaning fluid in the central duct to pass into the milk intake duct, andat a third cleaning stage: i) operating the pump in the original direction again,ii) placing the first valve back to the first position for blocking the milk intake duct again. 7. A method according to claim 6, wherein, in the second cleaning stage, the pump is only operated for pumping a volume of cleaning fluid which corresponds to the volume of the milk intake duct, and wherein the operation of the pump is reversed as soon as this volume has passed the pump.
