The present invention relates to a beverage preparation device having a water circulation system that includes a water source with an outlet, a pump with a support member for holding and securing the pump in the device, and an integral water conduit having an inlet and outlet for guiding water from the water source to the pump. The conduit outlet is connected to the pump and the water source outlet is connected to the water conduit inlet via an annular sealing member that forms an integral protruding portion of one of the conduit inlet or the source outlet. The pump support is integral with the water conduit, in particular with the conduit outlet.

1. A beverage preparation device having a water circulation system that comprises: a housing,a water source having an outlet,a pump having a support member for holding and securing the pump in the device housing, andan integral water conduit having an inlet and outlet for guiding water from the water source to the pump, with the conduit outlet connected to the pump;wherein the water source outlet is connected to the water conduit inlet via an annular sealing member that forms an integral protruding portion of one of the conduit inlet or the source outlet; andwherein the pump support is integral with the water conduit and separate from the housing. 2. The device of claim 1, wherein the pump support is integral with the conduit outlet of the water conduit. 3. The device of claim 1, wherein the conduit outlet incorporates electrical circuitry connected to the pump. 4. The device of claim 3, wherein the conduit outlet or the electrical circuitry is connected to the pump by a snap fit connector. 5. The device of claim 1, wherein the water source is a water tank for containing water having a level in the tank that is measured via an optical water level detector. 6. The device of claim 1, wherein the integral conduit has an intermediate portion that is connected to a sensor comprising a flow meter, pressure sensor or temperature sensor. 7. The device of claim 6, wherein the intermediate portion of the conduit has an intermediate outlet and intermediate inlet for guiding water into and out from the sensor between the water source and the pump, with the outlet and intermediate inlet being integral with the conduit extending from the water source to the pump. 8. The device of claim 1, wherein the annular sealing member is integral with the water conduit inlet and compressed against the source outlet, or vice versa, to seal the connection between the water conduit and water source. 9. The device of claim 1, wherein the pump support has a pump connector integral with the conduit or conduit outlet for mechanically connecting the pump to the support; and a foot member integral with the pump connector for securing the support in the beverage preparation device, with the conduit outlet optionally extending through the pump connector to a water inlet of the pump. 10. The device of claim 1, wherein the water conduit incorporates electrical circuitry connected to the pump. 11. The device of claim 1, wherein the water source comprises a tank for containing water and for supplying water to a pump of the device; and an optical sensor for measuring a water level in the tank, with the optical sensor comprising: a light emitter for emitting to the water in the tank a light beam (A,A′) that is deflectable by the water as a function of the water level; and a light detector for detecting the emitted light beam upon deflection, wherein the light emitter and light detector are arranged such that the emitted light beam (A,A′) is deflectable onto the detector when the water level reaches a predetermined lower value in the tank. 12. The device of claim 11, wherein the light detector is located at a bottom part of the water tank, the light emitter and detector being arranged so that the emitted light beam (A′) undergoes a succession of reflections and refractions and so that the detector receives a portion of the reflected light beam (A′) when the water level in the water tank reaches the predetermined lower value, or vice versa. 13. A beverage preparation device having a water circulation system that comprises: a housing,a water source having an outlet,a pump having a support member for holding and securing the pump in the device housing, andan integral water conduit having an inlet and outlet for guiding water from the water source to the pump, with the conduit outlet connected to the pump and incorporating electrical circuitry therein, and, wherein the conduit outlet or the electrical circuitry is connected to the pump by a snap fit connector;wherein the water source outlet is connected to the water conduit inlet via an annular sealing member that forms an integral protruding portion of one of the conduit inlet or the source outlet; andwherein the pump support is integral with the water conduit and separate from the housing to form a compact arrangement that conserves space within the housing. 14. The device of claim 13, wherein the integral conduit has an intermediate portion that is connected to a sensor comprising a flow meter, pressure sensor or temperature sensor. 15. The device of claim 14, wherein the intermediate portion of the conduit has an intermediate outlet and intermediate inlet for guiding water into and out from the sensor between the water source and the pump, with the outlet and intermediate inlet being integral with the conduit extending from the water source to the pump. 16. The device of claim 13, wherein the annular sealing member is integral with the water conduit inlet and compressed against the source outlet, or vice versa, to seal the connection between the water conduit and water source. 17. The device of claim 13, wherein the pump support has a pump connector integral with the conduit or conduit outlet for mechanically connecting the pump to the support; and a foot member integral with the pump connector for securing the support in the beverage preparation device, with the conduit outlet optionally extending through the pump connector to a water inlet of the pump. 18. The device of claim 13 wherein the water source comprises a tank for containing water and for supplying water to a pump of the device; and an optical sensor for measuring a water level in the tank, with the optical sensor comprising: a light emitter for emitting to the water in the tank a light beam (A,A′) that is deflectable by the water as a function of the water level; and a light detector for detecting the emitted light beam upon deflection, wherein the light emitter and light detector are arranged such that the emitted light beam (A,A′) is deflectable onto the detector when the water level reaches a predetermined lower value in the tank. 19. The device of claim 18, wherein the light detector is located at a bottom part of the water tank, the light emitter and detector being arranged so that the emitted light beam (A′) undergoes a succession of reflections and refractions and so that the detector receives a portion of the reflected light beam (A′) when the water level in the water tank reaches the predetermined lower value, or vice versa.
