9. The siphon arrangement as claimed in claim 1 , wherein a cross section of the tube is substantially constant over the entire tube length.

10. The siphon arrangement as claimed in claim 1 , wherein the tube is surrounded by a siphon wall.

11. A siphon arrangement comprising:

a housing with an inlet connection piece, an outlet connection piece, and a siphon seat arranged between the inlet connection piece and the outlet connection piece, and

a siphon element arranged in the siphon seat, said siphon element having a siphon portion and an inlet facing toward the inlet connection piece and an outlet opening into the siphon seat,

wherein water can be guided from the inlet connection piece via the inlet into the siphon portion and from the outlet into the siphon seat and then to the outlet connection piece,

wherein the siphon element is mounted in the housing in such a way as to be movable from a use position to a maintenance position, and, when in the maintenance position, can be removed from the housing via an access opening,

wherein the siphon element has the form of a bent tube,

wherein the siphon element is connected to the mounting element by means of a longitudinal guide,

wherein the siphon element is connected to the mounting element by means of a latching connection,

wherein said siphon element is pivotable, and

wherein the latching connection is part of said longitudinal guide or is formed separately from said longitudinal guide.

12. The siphon arrangement as claimed in claim 11 , wherein a seal, against which the inlet of the siphon element rests in a leak-tight manner, is arranged in an entry region of the inlet connection piece into the siphon seat, wherein the siphon element is pressed against the seal in the use position and wherein, shortly before or in the use position, respectively, the sealing surface of the seal is substantially at right angles to the longitudinal movement along the longitudinal guide.

13. A siphon arrangement comprising:

a housing with an inlet connection piece, an outlet connection piece, and a siphon seat arranged between the inlet connection piece and the outlet connection piece, and

a siphon element arranged in the siphon seat, said siphon element having a siphon portion and an inlet facing toward the inlet connection piece and an outlet opening into the siphon seat,

wherein water can be guided from the inlet connection piece via the inlet into the siphon portion and from the outlet into the siphon seat and then to the outlet connection piece,

wherein the siphon element is mounted in the housing in such a way as to be movable from a use position to a maintenance position, and, when in the maintenance position, can be removed, from the housing via an access opening,

wherein the siphon element has the form of a bent tube,

wherein at least one guide structure is arranged between the siphon seat and the siphon element, and

wherein the at least one guide structure is designed in such a way that the siphon element is pressed against the inlet connection piece during the rotation from the maintenance position to the use position.

14. The siphon arrangement as claimed in claim 13 , wherein the guide structure has a guide surface and a guide peg which strikes against the latter, wherein the guide surface is arranged in a fixed manner in the siphon seat and wherein the guide peg is arranged in a fixed manner on the siphon element and comes into contact with the guide surface and slides along the guide surface in the direction of the inlet connection piece during the movement into the use position.

15. The siphon arrangement as claimed in claim 13 , wherein the guide structure has a guide surface and a guide peg which strikes against the latter, wherein the guide surface is arranged in a fixed manner in the siphon seat and wherein the guide peg is arranged in a fixed manner on the siphon element and comes into contact with the guide surface and slides along the guide surface in the direction of the inlet connection piece during the movement into the use position and wherein the guide surface slopes at an angle to the line of movement of the guide peg from the maintenance position to the use position, wherein the guide surface is oriented substantially in the same direction as spa longitudinal guide between the siphon element and the mounting element when the siphon element is in the use position.
