Beverage maker
View Patent ↗A beverage maker includes a body and a cover movably attached to the body. The body includes therein (among other components), a hot liquid generator (HLG) having a tank, an inlet for receiving liquid into the tank and an outlet, at least one heater in thermal communication with the liquid in the HLG tank, and a discharge port in fluid communication with the outlet of the HLG for discharge of the liquid. The cover is movably attached to the body between a closed position and an open position. At least one valve permits the discharge of the liquid via the discharge port in a closed position of the cover. The at least one valve is mechanically actuated by the cover in the open position of the cover to substantially prevent the discharge of the liquid via the discharge port.
1. A beverage maker comprising:
a body;
a hot liquid generator (HLG) positioned within the body and having a tank, an inlet for receiving liquid into the tank and a first outlet;
at least one heater in thermal communication with the liquid in the HLG tank;
a discharge port in fluid communication with the first outlet of the HLG for discharge of the liquid;
a cover movably attached to the body between a closed position and an open position; and
a pressure release valve in operative engagement with a first orifice of a pressure release line, the pressure release valve in continuous fluid communication with a second outlet of the HLG via the pressure release line, the pressure release valve comprising a valve seat mounted to the cover and a complementary valve stem mounted to the body, the valve stem sealingly engaging the valve seat in the closed position of the cover, thereby preventing release of pressure within the tank therethrough, movement of the cover from the closed position to the open position mechanically disengaging the valve stem from the valve seat, thereby releasing pressure within the tank through the valve stem.
2. The beverage maker of claim 1 , further comprising a deflecting member extending between the cover and the body, and an orifice in the body, the orifice and the pressure release valve being substantially enclosed by the cover, the body and the deflecting member, such that fluid released from the pressure release valve flows into the orifice.
3. The beverage maker of claim 1 , further comprising a flexible tube fluidly communicating the HLG first outlet and the discharge port, and a pinch valve mounted onto the flexible tube, the pinch valve including a biasing member biasing the pinch valve into a pinching position, pinching the flexible tube and obstructing fluid flow from the HLG first outlet to the discharge port, the biasing member being mechanically engaged and actuated by the body into a release position in the closed position of the cover, permitting fluid flow from the HLG first outlet to the discharge port, and the biasing member returning the pinch valve to the pinching position in the open position of the cover.
4. A beverage maker comprising:
a body;
a hot liquid generator (HLG) positioned within the body and having a tank, an inlet for receiving liquid into the tank and a first outlet;
at least one heater in thermal communication with the liquid in the HLG tank;
a discharge port in fluid communication with the first outlet of the HLG for discharge of the liquid;
a cover movably attached to the body between a closed position and an open position; and
a pressure release valve in operative engagement with a first orifice of a pressure release line, the pressure release valve in continuous fluid communication with a second outlet of the HLG via the pressure release line, the pressure release valve mounted to the cover and comprising a valve stem, a valve seat, and a biasing member biasing the valve stem into disengagement from the valve seat, wherein the body engages and mechanically actuates the valve stem into sealing engagement with the valve seat in the closed position of the cover, against the bias of the biasing member, thereby preventing release of pressure within the tank therethrough, and the body being disengaged from the pressure release valve in the open position of the cover, such that the biasing member maintains the valve stem disengaged from the valve seat, thereby releasing pressure within the tank through the pressure valve stem.
5. The beverage maker of claim 4 , further comprising a deflecting member positioned between the cover and the body, and an orifice in the body, the deflecting member directing fluid released from the pressure release valve toward the orifice.
6. The beverage maker of claim 4 , further comprising a flexible tube fluidly communicating the HLG first outlet and the discharge port, and a pinch valve mounted onto the flexible tube, the pinch valve including a biasing member biasing the pinch valve into a pinching position, pinching the flexible tube and obstructing fluid flow from the HLG first outlet to the discharge port, the biasing member being mechanically engaged and actuated by the body into a release position in the closed position of the cover, permitting fluid flow from the HLG first outlet to the discharge port, and the biasing member returning the pinch valve to the pinching position in the open position of the cover.
