Abstract
A liquid dispensing unit and method for sensing temperature of an electric valve. In one embodiment, the liquid dispensing unit includes a manifold which has a liquid passageway adapted to connect to a source of heated liquid. An electrically operated dispensing valve is coupled to the manifold. The dispensing valve includes an external surface and a liquid passageway which is in fluid communication with the liquid passageway of the manifold. The dispensing valve is selectively operative to dispense the heated liquid. The liquid dispensing unit further includes a temperature sensing device operatively associated with the dispensing valve. The temperature sensing device has a sensing element contacting the external surface of the dispensing valve to measure the temperature of that external surface and thereby indirectly measure the temperature of the heated liquid within the dispensing valve.
