  The present invention relates to a faucet device, and more particularly, a faucet provided with a movable operation part for adjusting a water discharge temperature, and a hot and cold water mixing valve electrically driven based on the operation of the movable operation part. Relates to the device.

  In order to set the temperature discharged from the faucet device, a so-called electronic faucet is known that electrically drives a hot and cold mixing valve based on an analog operation of the operation unit (Patent Document). 1).

  In such a faucet device, the mixing of hot water flowing from the hot water supply pipe of the hot water mixing valve is increased as the operation amount of the operation part from the hot water pipe closing position where the flow rate of hot water flowing from the hot water pipe of the hot water mixing valve is zero is increased. The rate increases and the water discharge temperature rises. Moreover, as the operation amount from the hot water supply pipe closing position of the operation unit becomes smaller, the mixing ratio of hot water flowing from the hot water supply pipe of the hot water / water mixing valve decreases, and the discharged water temperature decreases.

JP 2007-332675 A

  In the water faucet device, the operation unit is operated toward the hot water supply pipe closing position to reduce the flow rate of hot water flowing from the hot water supply pipe of the hot water mixing valve to lower the water discharge temperature and to discharge only water. When the operation part reaches the hot water pipe closing position, the flow rate of hot water flowing from the hot water pipe of the hot water mixing valve decreases, and the water discharge temperature becomes close to the water temperature, so the user closes the hot water pipe. It may be misunderstood as something operated to the position. In this state, the hot water supply valve of the hot water / water mixing valve is not completely closed, and hot water may flow in from the hot water supply pipe little by little.

  Accordingly, an object of the present invention is to provide a water faucet device that can reliably close a hot water supply pipe of a hot and cold water mixing valve that is electrically driven based on an operation of a movable operation portion.

  In order to achieve the above object, a faucet device according to the present invention includes a movable operation part for setting a water discharge temperature, and a hot and cold water mixing valve electrically driven based on the setting of the movable operation part, The hot water mixing valve is a faucet device that can adjust the mixing ratio of hot water flowing in from the hot water supply pipe and water flowing in from the water supply pipe, and the mixing ratio of hot water flowing in from the hot water supply pipe is zero. When moving or rotating from the hot water supply pipe closing position so as to increase the mixing ratio of hot water, the movement distance or rotation angle from the hot water supply pipe closing position is detected in real time and corresponds to the movement distance or rotation angle. An operation detection unit for determining the set temperature in real time and a set value determination for determining the mixing rate setting value of the hot water mixing valve so that the mixing rate of hot water increases as the detected moving distance or rotation angle increases. And a drive unit that drives the hot and cold water mixing valve in response to the mixing rate setting value, and the movable operation unit is configured to increase the hot water mixing rate in order to raise the discharged water temperature from the hot water supply pipe closed position. To move or rotate to stop at the operating temperature position, and then move or rotate to decrease the mixing rate of hot water to lower the discharged water temperature, before the movable operation part returns to the hot water pipe closing position When the hot water supply pipe forced closing position is reached, the set value determination unit determines the mixing ratio set value of the hot water mixing valve so that the mixing ratio of hot water flowing from the hot water supply pipe becomes zero.

  In the faucet device of the present invention configured as described above, the movable operation unit is moved or rotated from the hot water supply pipe closed position so as to increase the mixing ratio of hot water in order to increase the discharged water temperature, and stopped at the use temperature position. Then, after moving or rotating so as to decrease the mixing ratio of hot water to lower the discharged water temperature, when the movable operation unit reaches the hot water supply pipe forced closing position before returning to the hot water supply pipe closed position, The mixing ratio setting value of the hot water mixing valve is determined so that the mixing ratio of hot water flowing in from the pipe is zero, so that the hot water pipe can be reliably closed even if the movable operation unit has not reached the hot water pipe closing position. It can be carried out. In addition, the hot water supply pipe forced closing position in the present invention does not indicate a position at the control limit of the hot water supply valve, but indicates a position that can be controlled so as to change the mixing ratio of hot water.

  In the embodiment of the faucet device according to the present invention, preferably, it further includes a water temperature sensor that detects the temperature in the water supply pipe, and the hot water supply pipe forced closing position is determined by the set water discharge temperature and the water temperature sensor determined by the operation detection unit. The position of the movable operation unit when the difference in the detected water temperature becomes a predetermined constant value may be used, or the predetermined constant temperature is subtracted from the set water discharge temperature corresponding to the use temperature position. The position of the movable operation unit corresponding to the detected temperature may be used, or when the difference between the set water discharge temperature determined by the operation detection unit and the water temperature detected by the water temperature sensor is at the use temperature position. It may be the position of the movable operation unit when the value becomes a predetermined ratio with respect to the difference between the set water discharge temperature and the water temperature detected by the water temperature sensor.

  Further, in the embodiment of the faucet device according to the present invention, preferably, the hot water supply pipe forced closing position may be a position at a predetermined moving distance or rotation angle determined in advance from the hot water supply pipe closing position, The position may be a position obtained by subtracting a predetermined constant moving distance or rotation angle from the use temperature position, or a predetermined constant ratio with respect to the movement distance or rotation angle from the hot water pipe closing position to the use temperature position. The movable operating unit may be moved or rotated from the hot water supply pipe closing position by a distance or an angle.

  In the embodiment of the faucet device according to the present invention, preferably, when the movable operation unit reaches the hot water supply pipe forced closing position, the moving distance or the rotation angle from the use temperature position is a predetermined distance or When the angle is smaller than the angle, the set value determination unit cancels the determination of the mixing rate setting value of the hot and cold water mixing valve so that the mixing rate of hot water flowing from the hot water supply pipe becomes zero. Preferably, when the movable operation part reaches the hot water supply pipe forced closing position, the set water discharge temperature when the movable operation part moves from the set water discharge temperature when the movable operation part is at the use temperature position to the hot water supply pipe forced closing position. When the difference is smaller than a predetermined amount, the set value determination unit cancels determining the mixing rate setting value of the hot water mixing valve so that the mixing rate of hot water flowing from the hot water supply pipe becomes zero.

  In the faucet device configured as described above, the setting is performed when the moving distance or the rotation angle from the use temperature position is smaller than a predetermined distance or angle, or when the movable operation unit is at the use temperature position. When the temperature difference from the temperature to the hot water pipe forced closing position is smaller than a predetermined amount, it is estimated that the user does not want to discharge only water, and the hot water from the hot water pipe Do not stop the inflow. Therefore, the user can adjust the water discharge temperature as it is.

  As described above, according to the faucet device of the present invention, the hot water supply pipe of the hot and cold water mixing valve that is electrically driven based on the operation of the movable operation portion can be reliably closed.

The water discharge temperature can be changed by controlling the motor 16a, changing the position of the valve body, and changing the mixing ratio of the amount of hot water flowing in from the hot water supply pipe 14a and the amount of water flowing in from the water supply pipe 14b. A temperature sensor 22 connected to the control unit 20 is provided between the hot and cold mixing valve 16 and the flow rate adjusting valve 18, and the control unit 20 performs feedback control of the water discharge temperature based on a signal from the temperature sensor 22. preferable. Further, it is preferable that a water temperature sensor 23 for detecting the water temperature in the water supply pipe 14 b is provided in the water supply pipe 14 b and connected to the control unit 20.

  A valve body (not shown) of the flow rate adjusting valve 18 is connected to the motor 18a and is electrically driven by the control unit 20 based on the operation of the movable operation unit 8 for adjusting the discharged water flow rate. By controlling the motor 18a and changing the position of the valve body, the water discharge flow rate can be changed.

  The movable operation parts 8 and 10 have the same structure. As shown in FIG. 3, each of the movable operation units 8 and 10 includes a hollow cylindrical operation unit body 26 that passes through the wash counter 4 in the vertical direction and is fixed to the wash counter 4, and the operation unit body 26 from above. A cylindrical operation handle 28 is attached so as to cover and to be rotatable with respect to the operation unit main body 26. Specifically, the operation portion main body 26 has a flange portion 26a formed at the upper portion thereof, a male screw portion 26b formed at the lower portion thereof, a through hole 26c, and a diameter expansion formed at the lower portion of the through hole 26c. The diameter-expanded step portion 26d has a female screw portion 26e. The operation portion main body 26 is fixed to the wash counter 4 via a packing and washer 31 by a nut 30 screwed into the male screw portion 26b.

The operation handle 28 and the rotary encoder 32 can be rotated infinitely clockwise and counterclockwise. The rotary encoder 32 is preferably of a type that can detect the direction of rotation.

  As shown in FIG. 2, the control unit 20 includes an operation detection unit 40 that detects a rotation direction position of the operation handle 28 of the movable operation units 8 and 10 in real time, and a flow rate or hot water mixing according to the detected rotation direction position. And a set value determining unit 44 for determining a set value of the ratio.

  Specifically, the operation detection unit 40 is configured to detect the rotational direction position of the operation handle 28 of the movable operation units 8 and 10 based on a pulse signal from the rotary encoder 32. Further, the operation detection unit 40 determines whether the moving direction of the movable operation unit 10 and the operation handle 28 is an increasing direction (clockwise) for increasing the flow rate or temperature, or the flow rate or temperature based on the pulse signal from the rotary encoder 32. It is configured to detect whether the direction of decrease (counterclockwise) is decreased.

  In the movable operation portion 8 for adjusting the flow rate, the rotational direction position is determined when the operation handle 28 is rotated from the water stop position where the flow rate discharged from the flow rate adjustment valve 18 is zero so as to increase the flow rate. This is the rotation angle from the water stop position.

  In the temperature adjusting movable operation unit 10, the rotation direction position moves the operation handle 28 from the hot water supply pipe closed position where the mixing ratio of hot water flowing in from the hot water supply pipe is zero or so as to increase the mixing ratio of hot water. It is a rotation angle from the hot water supply pipe closing position when it is rotated. Moreover, it is good for the operation detection part 40 to determine the setting water discharge temperature corresponding to the rotation angle from a hot water supply pipe closed position in real time.

  The hot water supply pipe closing position is preferably determined by the rotational direction position of the operation handle 28 of the movable operation unit 10. As a modification, the water temperature detected by the water temperature sensor 23 is compared with the set water discharge temperature while rotating the operation handle 28 of the movable operation unit 10, and the operation handle 28 when the water temperature is equal to the set water discharge temperature is compared. The position may be determined as a hot water supply pipe closing position. Further, a flow rate sensor may be provided in the hot water supply pipe 14a, and the operation handle 28 of the movable operation unit 10 may be rotated to determine the position of the operation handle 28 when the flow occurs in the hot water supply pipe 14a as the hot water supply pipe closing position. . This method is preferable when the thermo faucet is driven by a motor.

  The set value determination unit 44 determines the rotation direction position (rotation angle) of the operation handle 28 of the movable operation unit 8 for adjusting the flow rate detected by the operation detection unit 40 and the discharge water flow rate to be determined by the set value determination unit 44. The relationship between them is stored by a map or the like. The set value determination unit 44 determines an adjustment set value for the flow rate so that the flow rate increases as the detected rotation angle increases.

  Further, the set value determination unit 44 is configured to detect the rotational direction position (rotation angle) of the operation handle 28 of the temperature adjusting movable operation unit 10 detected by the operation detection unit 40, and hot water mixing to be determined by the set value determination unit 44. The relationship with the mixing ratio set value of the valve 16 is stored as a map or the like. The set value determination unit 44 determines the adjustment set value with respect to the temperature so that the mixing ratio of hot water flowing from the hot water supply pipe 14a increases as the detected rotation angle increases.

  Next, the operation of the control unit 20 will be described.

  When the flow rate adjustment valve 18 is operated by the movable operation unit 8 for adjusting the discharged water flow rate, the rotary encoder 32 generates a pulse by rotating the operation handle 28 of the movable operation unit 8. The operation detection unit 40 detects the rotation direction position (rotation angle) and rotation direction of the operation handle 28 from the number and phase of pulses. Next, the set value determination unit 44 determines an adjustment set value for the water discharge flow rate in accordance with the rotational direction position. The controller 20 drives the motor 18a of the flow rate adjustment valve 18 in accordance with the adjustment set value. The operation detection unit 40 detects the pulse of the rotary encoder 32 in real time, and the control unit 20 repeats the above operation.

  When the hot water mixing valve 16 is operated by the movable operation unit 10 for adjusting the water discharge temperature, the rotary encoder 32 generates pulses by rotating the operation handle 28 of the movable operation unit 10. The operation detection unit 40 detects the rotation direction position (rotation angle) and rotation direction of the operation handle 28 from the number and phase of the pulses, and determines the set water discharge temperature corresponding to the rotation direction position. Next, the set value determination unit 44 determines the mixing ratio set value of the hot water / water mixing valve 16 according to the rotation direction position (set water discharge temperature). When determining the mixing ratio set value, it is preferable that feedback control using the temperature sensor 22 is performed. The controller 20 drives the motor 16a of the hot water / water mixing valve 16 in accordance with the mixing ratio set value. The operation detection unit 40 detects the pulse of the rotary encoder 32 in real time, and the control unit 20 repeats the above operation.

  Further, the operation handle 28 of the movable operation unit 10 is rotated from the hot water supply pipe closed position so as to increase the mixing ratio of hot water in order to increase the water discharge temperature, stopped at the use temperature position, and then the water discharge temperature is decreased. Therefore, after rotating so as to reduce the mixing ratio of hot water, when the operation handle 28 of the movable operation unit 10 reaches the hot water supply pipe forced closing position before returning to the hot water supply pipe closed position, the set value determination unit 44 The mixing ratio set value of the hot water mixing valve 16 is determined so that the mixing ratio of hot water flowing in from the hot water supply pipe 14a becomes zero, and only water is discharged from the hot water mixing valve 16.

  Thereby, even if the movable operation part 10 has not reached the hot water supply pipe closing position, the hot water supply pipe 14a of the hot water mixing valve 16 can be reliably closed.

  Further, when the operation handle 28 of the movable operation unit 10 reaches the hot water supply pipe forced closing position, the rotation angle from the use temperature position is smaller than a predetermined angle, or the operation of the movable operation unit 10 When the difference between the set water discharge temperature when the handle 28 is at the use temperature position and the set water discharge temperature when the handle 28 is moved from the hot water supply pipe forced closing position is smaller than a predetermined amount, the set value determination unit 44 The determination of the mixing ratio set value of the hot water mixing valve 16 is canceled so that the mixing ratio of hot water flowing in from 14a becomes zero.

  In this case, it is estimated that the user does not want to discharge only water, and the inflow of hot water from the hot water supply pipe is not stopped. Therefore, the user can adjust the water discharge temperature as it is.

  Hereinafter, with reference to FIG.4 and FIG.5, the Example of the hot water supply pipe forced closing position is described. In FIG. 4, the hot water pipe closing position of the operation handle 28 is represented by a0, and the positions of the operating water discharge temperatures tL and tL ′ are represented by aL and aL ′.

  In FIG. 4A, the hot water supply pipe forced closing position is determined by the set water discharge temperature t1 and the water temperature sensor 23 in both cases of the use water discharge temperatures tL and tL ′ when the operation handle 28 is stopped at the positions aL and aL ′. This is the position a1 of the operation handle 28 when the detected difference in water temperature tw reaches a predetermined constant value ΔT1.

  In FIG. 4B, in the case of the used water discharge temperature tL when the operation handle 28 is stopped at the position aL, the hot water supply pipe forced closing position is a predetermined temperature determined from the set water discharge temperature tL corresponding to the position aL. This is the position a2 of the operation handle 28 corresponding to the temperature t2 obtained by subtracting ΔT2. When the operation handle 28 stops at the used water discharge temperature tL ′, since tL ′ <ΔT2, there is no hot water supply pipe forced closing position, and the operation handle 28 is rotated to the position a0 corresponding to the water discharge temperature (water temperature) tw. Thus, the inflow rate of hot water from the hot water supply pipe 14a becomes zero.

  In FIG. 4 (c), in both cases of the used water discharge temperatures tL and tL ′ when the operation handle 28 stops at the positions aL and aL ′, the hot water supply pipe forced closing position is set in advance with respect to the used water discharge temperatures tL and tL ′. The positions a3 and a3 ′ of the operation handle 28 corresponding to the determined temperatures t3 and t3 ′ (for example, 20%). If the hot water supply pipe forced closing position of FIG. 4 (c) is adopted, the hot water supply pipe 14a can be closed earlier than the case where the hot water supply pipe forced closing position of FIG. 4 (a) is adopted when the water discharge temperature tL is high. .

  In FIG. 5A, the hot water supply pipe forced closing position is determined in advance from the hot water supply pipe closing position a0 in both of the positions aL and aL ′ when the operation handle 28 stops at the used water discharge temperatures tL and tL ′. A position a4 at a certain rotation angle.

  In FIG. 5B, in the case of the position aL when the operation handle 28 stops at the use water discharge temperature tL, the hot water supply pipe forced closing position is a position a5 obtained by subtracting a predetermined rotation angle ΔA from the position aL. It is. In the case of the position aL ′ when the operation handle 28 stops at the use water discharge temperature tL ′, since aL′−a0 <ΔA, there is no hot water supply pipe forced closing position, and the operation handle 28 is set to the water discharge temperature (water temperature) tw. By rotating to the corresponding position a0, the inflow rate of hot water from the hot water supply pipe 14a becomes zero.

  In FIG. 5C, in both the positions aL and aL ′ when the operation handle 28 stops at the used water discharge temperatures tL and tL ′, the hot water supply pipe forced closing position is the position aL from the hot water supply pipe forced closing position a0. , Positions a6 and a6 ′ rotated from the hot water supply pipe forced closing position a0 by a predetermined constant ratio (for example, 20%) with respect to the rotation angle up to aL ′. If the hot water supply pipe forced closing position of FIG. 5 (c) is adopted, the hot water supply pipe 14a can be closed earlier when the water discharge temperature tL is large than when the hot water supply pipe forced closing position of FIG. 5 (a) is adopted. .

Needless to say, these are also included within the scope of the present invention.

  In the above embodiment, the rotary encoder 32 is used to detect the rotation direction position (rotation angle) in the operation detection unit 40, but other sensors may be used.
