Beverage preparation machine

A beverage preparation machine for preparing a beverage from a beverage ingredient pod, the machine comprising:

• an extraction device for extracting a beverage ingredient by supplying an extraction liquid into the pod, the extraction device comprising:
• upstream and downstream pod enclosing parts relatively movable between an open position for inserting and/or ejecting the pod and a closed position for forming an extraction chamber enclosing the pod during extraction,
• the upstream pod enclosing part defining a cage and bearing:
• an upstream piercing arrangement for opening a bottom wall of the pod, and
• a liquid injector,
• the downstream pod enclosing part comprising a downstream piercing arrangement for opening a lid of the pod, the downstream pod enclosing part further comprising a beverage outlet for dispensing extracted beverage,
• a liquid supply system connected to the upstream enclosing part, the liquid supply system comprising:
• a liquid supply,
• a pump to drive liquid from the liquid supply,
• a heater to adapt a temperature of the liquid,
• a motor to actuate movement of at least one of the upstream and downstream pod enclosing parts between the opened position and the closed position;
• and
• a control system configured to control actuation of the motor,
• wherein the liquid supply system comprises:
• a cold tube to supply cold pumped water from the pump, and a hot tube to supply pumped hot water from the heater, the said cold tube and the said hot tube supplying a common connector with water,
• a first peristaltic valve to enable supply of the common connector with water either from the cold tube or from the hot tube,
• a first tube to supply water to the liquid injector, and a second tube to supply water to an in-cup beverage dispensing area, the common connector supplying the first and second tubes with the water,
• a second peristaltic valve to enable supply of the first tube or the second tube with water dispensed through the common connector,
• and wherein the machine comprises mechanical triggers attached to at least one of the upstream and downstream pod enclosing parts, the triggers designed and positioned to close or open water paths in the hot and cold tubes and the first and second tubes and pod paths in the extraction device according to the movement of at least one of the upstream and downstream pod enclosing parts during preparation of the beverage from the pod.
