s operation . to draw water from the water tank 3 , the pump 18 pumps water from the water tank 3 out of the water system valve 8 into the tubing 10 . the water runs through the tubing 10 and is measured by the flow meter 16 . the flow meter 16 controls how much water is to be drawn from the water tank 3 . the water is then pumped through the heater 20 by the pump 18 . after the water is heated , it is routed from the flow valve 22 either to be brewed as a beverage or to be dispensed as hot water . the routing directs water to either a water line 10 c that dispenses hot water or a beverage line 10 b that dispenses the beverage . if a user desires hot water , the water simply flows from the flow valve 22 through water line 10 c into the water nozzle 30 and into a waiting cup 50 that may be located on a stand 36 . the water nozzle 30 is separate from the beverage nozzle 28 so that a user can ensure that clean water is dispensed . when a beverage is to be brewed , water flows from the flow valve 22 through the beverage line 10 b to the brewing system 40 . when a user desires to operate the appliance and brew a beverage , a command is pressed on the user interface 32 . the brewing system 40 comprises a brewing chamber 48 , at least one nozzle 28 and piercing needles 24 . a beverage capsule 26 is placed into the brewing system 40 at the brewing chamber 48 . the brewing chamber 48 is anticipated to be operable in the closed position so to access the chamber 48 , it must be opened at a brewer system door 44 . the action closing of brewing system door 44 pushes the beverage capsule 26 down to pierce onto output needle 49 at the bottom of brewing chamber 48 . this point where the output needle 49 punctures the beverage capsule 26 provides an output hole at which brewed beverage can exit the beverage capsule 26 . the brewing chamber 26 also comprises an input needle 24 located in the brewer system door 44 . this input needle 24 can pierce the top of a beverage capsule 26 creating an input hole to allow to flow into the capsule 26 from the flow valve 22 . this input needle 24 is covered by movable needle cover 46 seen in fig7 a and 7b . movable needle cover 46 is moved by actuator 70 . the brewing system door 44 has an open and closed position . the needle cover 46 covers the needle 24 when the brewing system door 44 is in the open position as seen in fig7 a . when the door 44 rotates to the closed position the actuator 70 moves the needle cover 46 into a retracted position and exposes needle 24 to pierce the beverage capsule 26 . once the beverage capsule is in place within the brewing chamber 48 , a beverage can be brewed within the brewing chamber 48 as water flows into the capsule 26 . heated water flows from the flow valve 22 , through tubing 10 , through needle 24 , into beverage capsule 26 . the beverage is brewed within the capsule 26 and flows out of the capsule 26 through the output hole into the beverage nozzle 28 . brewed beverage then flows from the beverage nozzle 28 into the cup 50 located on stand 36 . turning to fig5 a and 5b , the stand 36 folds into and out of the appliance 2 . the stand 36 is also removable as seen in fig6 . fig1 depicts a view of the appliance 2 where the stand 36 is removed and the cup 50 overhangs the appliance &# 39 ; s support surface 76 . the appliance is equipped with a safety sensor 58 . this sensor senses whether or not a user opens the brewing chamber while a hot beverage is being brewed . if the brewing system door 44 is opened while hot water or residual steam is being pumped from the flow valve 22 into the brewing system 40 , this safety sensor 58 triggers the water to stop flowing and switches the flow valve to direct the water to instead flow into the water line 10 c and out water nozzle 30 away from a user . throughout the specification and claims the word “ comprise ” and its derivatives are intended to have an inclusive rather than exclusive meaning unless the contrary is expressly stated or the context requires otherwise . that is , the word “ comprise ” and its derivatives will be taken to indicate the inclusion of not only the listed components , steps or features that it directly references , but also other components , steps or features not specifically listed , unless the contrary is expressly stated or the context requires otherwise . it will be appreciated by those skilled in the art that many modifications and variations may be made to the methods of the invention described herein without departing from the spirit and scope of the invention .
