1. A suction unit suitable for suctioning an object according to Bernoulli's principle, comprising:
a suction body with an adjoining suction plate having a front side facing away from the suction body and an outer peripheral edge;
the suction body comprising a plurality of entry channels, through which a gaseous medium is introducible through the suction body toward the front side of the suction plate and into a deflection channel, which is one of:
delimited on one side by the front side of the suction plate and on another side by a deflection head of a deflection unit, or
delimited on one side by the front side of the suction plate and on another side by the object when the object is suctioned, wherein the deflection channel is arranged so that the gaseous medium is guidable to outside the outer peripheral edge; and
a deflection chamber, which is arranged in a center of the suction plate, and which is adjoined on one side by the plurality of entry channels and on another side by a plurality of suction channels which are sunk into the suction plate and extend towards the outer peripheral edge of the suction plate,
wherein the suction body is constructed in one piece,
wherein the plurality of entry channels branch from an inlet channel,
wherein the plurality of entry channels run inside the suction body inclined outwards towards the suction plate, and
wherein the deflection unit has a pin-shaped mounting element which adjoins the deflection head and is held in a mounting channel or the inlet channel.
