First Claim
Patent Images
1. An electronic faucet comprising:
- a valve assembly including a valve housing having an interior region for receiving a fluid, a solenoid valve positioned to control fluid flow through the interior region, the solenoid valve including a solenoid coil and a moveable valve member operably coupled to the solenoid coil;
a controller operably coupled to the solenoid valve, the controller including an electronic circuit board coupled to the valve assembly and a processor mounted to the electronic circuit board to control the solenoid valve, the solenoid coil being mounted to the electronic circuit board;
a temperature sensor mounted to the electronic circuit board; and
a heat transfer device extending between the temperature sensor and the interior region to transfer heat from fluid in the interior region to the temperature sensor.

Abstract
An electrically operable valve assembly for an electronic faucet includes a valve housing having an interior region for receiving a fluid, a solenoid valve, and a temperature sensor positioned outside the interior region. A heat transfer device extends between the temperature sensor and the interior region to transfer heat from fluid in the interior region to the temperature sensor. A controller is in communication with the temperature sensor and operative to control the solenoid valve.
