Automatic liquid dispenser

A liquid dispenser for transfer of liquid from a storage container to a receiving container having a receiving aperture facing upwards, comprising a flow controller, a liquid conductor, a liquid outlet element, a vertical actuator, a spatiality sensor, a substantially horizontally arranged sheet shaped horizontal support and a control unit,

• wherein:
• said flow controller is selected from the group of flow controllers consisting of valves and pumps and adapted to be in either an on-state, in which said liquid is transferred from said storage container via said liquid conductor and said liquid outlet element and said receiving aperture to said receiving container, or an off-state, in which said liquid is prevented from being transferred from said storage container to said receiving container, as dependent on electrical input from said control unit;
• said vertical actuator is in mechanical communication with said liquid outlet element and adapted to set said liquid outlet element in a maximum spatial state, in which said liquid outlet element is arranged at a maximum distance from said receiving container without contacting the same, or in a minimum spatial state, in which said liquid outlet element is arranged at a minimum distance above said receiving container without contacting the same and simultaneously arranged with its liquid exit hole in the vertical projection of the receiving aperture, as dependent on electrical input from said control unit;
• said spatiality sensor is adapted to detect a force change being due to the transition between a non-contacting state, in which said liquid outlet element is not contacting said receiving container, and a contacting state, in which said liquid outlet element is contacting said receiving container, and to provide information on such detection of force change in the form of electrical output to said control unit;
• said horizontal support having said spatiality sensor arranged at its upper or lower side and being adapted to allow placement of said receiving container on its upper side;
• and
• said control unit is adapted to give electrical output to said vertical actuator and to said flow controller, as dependent on the processing of electrical input from said spatiality sensor.
