  • the Hall-effect sensor may determine the angular or rotational position of the disc 128 and hence shaft 122 based upon the detection of magnets. It should be appreciated that other sensors or encoders may be used for sensor 124 and device 126.
  • a torque sensor or a capacitive touch sensor may be used to provide an indication of manual input from the user applied to the handle 102.
  • Rotary position sensor 124 provides a digital signal to a controller 132 that indicates the water temperature desired by the user.
  • the controller 132 utilizes the signal indicative of the desired temperature to establish a set-point temperature.
  • a temperature sensor 134 such as a thermistor, is in thermal communication with the mixed water passing through the outlet 118. More particularly, the temperature sensor 134 provides a signal indicative of the mixed water temperature to the controller 132. Controller 132 compares the set-point temperature, as detected by the temperature sensor 134 following manual adjustment as indicated by the angular position sensor 124, and adjusts the drive motor 104 to maintain the desired set-point temperature.
  • a clutch mechanism (not shown) may be used to release a locked gear drive of the drive motor 104 when manual control of the valve member 120 is required (i.e., manual mode of operation). Alternatively, a double-axle shaft stepper motor arrangement could be utilized.
  • One shaft 106 drives the valve member 120, while the opposing shaft 122 connects to the control handle 102.
  • the field windings (not shown) within motor 104 may be released, allowing manual control of the valve member 120 via the operator handle 102.
  • the field windings may be re-engaged, and the controller 132 returns to an automatic mode, illustratively a stepping (either one-half or micro-step) mode.
  • a rotationally loose coupling may be provided to allow the shafts 106, 122 to be adjusted without substantial resistance or conflicting rotational movement from the motor 104.
  • an illustrative method of operation begins at block 150 with a user activating the mixing valve 100 by turning the manual handle 102 to either a visual positional temperature set-point or by sampling the mixed temperature by hand.
  • the electronic controller 132 is inactive.
  • the controller 132 determines, based upon a signal received from the sensor 124, whether the manual handle 102, and hence shaft 122, is being rotated by user input. More particularly, the controller 132 determines through input from rotary position sensor 124 whether the shaft 122 is being moved independently, or without assistance, from the motor 104. Alternatively, the controller 132 could determine whether user input is applied to the handle 102 through signals received from a torque sensor or a touch sensor.
  • the sensor 124 may be a rotary position sensor, a touch sensor, or a torque sensor.
  • the process returns to immediately before block 152. If the handle 102 has been rotated, then the valve member 120 is adjusted accordingly. More particularly, the motor 104 is illustratively released from shafts 106, 122, such that rotation of handle 102 moves valve member 120 with little or no resistance from motor 104.
  • the controller 132 detects this event at block 156 by input from sensor 124. More particularly, this event may be detected either through the delay of input from the sensor 124 or by lack of input from a touch sensor or a torque sensor coupled to the handle 102.
  • the controller 132 When the controller 132 recognizes this event, it assumes the mixed temperature is at the desired value and stores the current mixed temperature measured by sensor 134 as the target set-point temperature at block 158. At block 160, the controller 132 begins controlling the motor 104 to maintain the mixed temperature proximate to the target set-point temperature. At this point, the control valve 100 behaves generally as a conventional electronic thermostatic valve. More particularly, if the mixed temperature should drift or deviate from the stored target set-point temperature, the controller 132 at block 162 engages the motor 104 in the appropriate direction and speed to compensate for the error and bring the mixed temperature back to the desired set-point temperature, after which the motor 104 disengages to allow the handle 102 to rotate freely to allow new set-point temperature changes to occur.
  • the controller 132 determines through the rotary position sensor 124 (or through a touch sensor or a torque sensor input as detailed herein) that the shaft 122 is being moved without the aid of the motor 104 (block 164), it relinquishes control of the shafts 106, 122 to the user to define a new set-point temperature.
  • the controller 132 detects the user has released, it then resumes control using the current temperature as the new set-point temperature by returning to block 158.
  • a touch or torque sensor may be used to detect user input or intervention rather than the rotary position sensor 124, since the possibility exists that the user may like to make adjustments at the same moment the motor 104 is engaged by the controller 132 attempting to control set-point temperature. This would result in the two systems (human and electronic) fighting for control.
  • the user may need to physically overpower the motor 104 in order for the controller 132 to detect asynchronous inputs from the motor 104 and the position sensor 124.
  • the electronic system i.e. motor 104 relinquishes control whenever the user makes a set-point temperature change and then regains it immediately as soon as the input is released and relinquished.
  • the controller 132 simply shuts down input to the motor 104. No other manual input is necessary to provide for manual operation.
  • the mixing valve assembly 100 simply behaves like a conventional unregulated mixing valve.
  • the mixing valve assembly 200 includes many of the same features detailed herein with respect to electronic mixing valve assembly 100. As such, similar components are identified by like reference numbers.
  • a torque sensor 202 is positioned intermediate the control handle 102 and the motor 104. More particularly, the torque sensor 202 is operably coupled to the shaft 122 and is configured to detect the magnitude and direction of torque therein.
  • Electronic mixing valve assembly 200 also includes a user interface 204 including a control pad 206 having user input buttons to provide for additional input from the user.
  • the control pad 206 illustratively includes an up button 208 and a down button 210 which may be depressed by the user to raise and lower, respectively, the set-point temperature.
  • a plurality of preset buttons 212 are also provided and may provide preset set-point temperatures to the controller 132 when depressed.
  • a temperature indicator illustratively a liquid crystal display 214, provides for a visual indication of the temperature detected by the temperature sensor 134.
  • An ON/OFF button 216 is provided to activate or deactivate the valve assembly 200.
  • the user in operation the user illustratively opens the valve 108 by rotating the control handle 102 and hence shaft 122.
  • the torque sensor 202 provides a signal of torque in shaft 122 to the controller 132 which, in response, energizes the motor 104 to rotate shaft 122 in the same direction.
  • the controller 132 adjusts the motor 104 in an attempt to minimize torque in shaft 122.
  • the motor 104 is energized to follow the direction and the speed of the control handle 102. This results in corresponding rotation of shaft 106 and adjustment of valve member 120.
  • the torque minimization process performed by the controller 132 results in opening the valve 108 or adjusting temperature by movement of valve member 120, and provides for consistent easy operation of the valve 108.
  • the controller 132 When a user releases the handle 102, the torque drops and the controller 132 releases the motor 104. The controller 132 then stores the set-point temperature as indicated by the temperature sensor 134. The valve assembly 200 now behaves as a conventional electronic mixing valve using the stored mixed temperature as the set- point and adjusting the temperature by controlling the motor 104 as necessary.
  • the torque sensor 202 sends a signal to the controller 132.
  • the signal provides an indication of the torque magnitude and direction.
  • the controller 132 rotates the motor 104 in the same direction attempting to minimize torque within the shaft 122.
  • the rotary position sensor 124 is optional, but may be included to aid in defining the temperature set-point without the need to wait for the mixed temperature to reach the sensor 134.
  • the controller 132 releases the motor 104 allowing it to free-wheel. In other words, the shafts 106, 122 are free to rotate with little or no resistance from the motor 104.
  • valve assembly 200 can be used as a conventional mixing valve without temperature or pressure balance compensation.
  • Using the valve assembly 200 allows for simple intuitive operation similar to conventional manual valves while allowing full electronic control and the associated benefits plus manual override without user intervention.
