Pump operated beverage maker

摘要

A beverage maker includes a body and a cover movably attached to the body. The body includes therein (among other components), a tank, a pump, a controller, a switch electrically coupled with the pump, and a pressure release valve in fluid communication with at least the pump and tank for releasing the pressure therein. The cover mechanically actuates the switch into an “on” position, to maintain the pump in an inoperable condition, and mechanically actuate or release the pressure release valve into one of an open or closed position, upon movement of the cover to the closed position thereof The cover releases the switch for return into the “off” position, placing the pump in an operational condition, and mechanically actuating or releasing the pressure release valve into the other of the open or closed positions, upon movement of the cover from the closed position toward the open position.

主权项

1. A beverage maker comprising:
a body housing therein:
a reservoir for receiving a liquid to be used for preparing a beverage;a hot liquid generator (HLG) having an inlet, an outlet and a tank, the inlet of the HLG being connected to the reservoir for receiving liquid into the tank;at least one heater in thermal communication with liquid in the HLG tank;a discharge port in fluid communication with the outlet of the HLG;a pump fluidly connected with the HLG tank for displacing liquid out of the tank outlet to the discharge port;a controller configured to actuate the at least one heater and the pump;a switch electrically coupled with the pump, the switch being biased into an “off” position, to maintain the pump in an inoperable condition, and being actuatable into an “on” position, placing the pump in an operational condition; anda pressure release valve in fluid communication with at least the HLG tank, the pressure release valve being biased into one of an open position for releasing pressure within the tank therethrough and a closed position for preventing the release of pressure within the tank therethrough, and being actuatable into the other of the open and closed positions; and a cover movably attached to an upper end of the body and being movable between an open position, to provide access to the reservoir, and a closed position, closing the upper end; wherein the cover:
mechanically actuates the switch into the “on” position and mechanically actuates or releases the pressure release valve into one of the open and closed positions, upon movement of the cover to the closed position thereof, andreleases the switch for return into the “off” position and mechanically actuates or releases the pressure release valve into the other of the open and closed positions, upon movement of the cover from the closed position toward the open position.
