  In the electronic faucet device of the prior art, water having a flow rate or temperature corresponding to the operation of the user is discharged, but no consideration is given to erroneous operation. For example, if the operation unit is operated at high speed to quickly discharge water and the operation amount of the operation unit is accidentally rotated beyond the water amount setting position corresponding to the easy-to-use water discharge amount, the water discharge amount will increase too much. , There is a risk of splashing water from the installed sink or basin and soiling clothes and surroundings. Further, if the same operation is performed at the time of temperature setting, high-temperature water having a temperature higher than a desired temperature may be discharged, which may waste heat energy and cause discomfort to the user.

  There is a conventional hot and cold water mixing faucet that can be temperature-controlled mechanically as one that can be applied to the above problem. This has a lock button in the water discharge temperature setting part, and it cannot be set to a temperature higher than a specified value unless the button is pressed. However, with this method, when the user desires high-temperature water discharge, the user must always press the lock button, which is troublesome.

  Therefore, an object of the present invention is to provide a water faucet device that can bring the operation of the faucet device closer to the operation desired by the user and improve the operation feeling of the user.

  In order to achieve the above object, the water faucet device according to the present invention has a flow rate or temperature controlled by a movable operation part for adjusting the flow rate or temperature and a valve body electrically driven based on the operation of the movable operation part. A faucet device having a flow rate adjustment valve or a hot and cold water mixing valve to be adjusted, an operation detection unit that detects the moving speed or rotation speed of the movable operation unit in real time, and as the movement speed or rotation speed is increased A drive speed determination unit that determines the valve body drive speed so as to increase the valve body drive speed of the flow rate adjustment valve or the hot water / water mixing valve, and a flow rate or temperature adjustment setting value based on the moving speed or rotation speed of the movable operation unit And a drive unit for driving the valve body of the flow rate adjustment valve or the hot and cold water mixing valve at the valve body drive speed, and the moving speed or rotation speed of the movable operation part is determined in advance. If the adjustment set value determined by the set value determining unit is greater than or equal to a predetermined high flow rate set value or high temperature set value, the drive speed determining unit The drive speed is determined to be 0.

  In the faucet device of the present invention configured as described above, the driving speed determination unit determines the valve body driving speed so as to increase the valve body driving speed as the moving speed or the rotational speed is increased. When the moving speed or rotational speed of the part is high, it is estimated that the user desires rough adjustment of the flow rate or temperature, and the valve body drive speed of the flow rate adjustment valve or the hot water mixing valve is increased. Thereby, the adjustment set value of the flow rate or the temperature can be quickly reached the target adjustment set value desired by the user. Further, when the moving speed or rotational speed of the movable operation unit is low, it is estimated that the user desires to finely adjust the flow rate or temperature, and the valve body drive speed of the flow rate adjustment valve or the hot water / water mixing valve is reduced. . Thereby, the adjustment set value can be gradually brought closer to the target adjustment set value desired by the user. On the other hand, when the moving speed or rotational speed of the movable operation unit is large, the moving speed or rotational speed becomes too higher than expected by the user, or the user's operation cannot catch up, and the flow rate or temperature adjustment setting value May be larger than the adjustment setting desired by the user. In the faucet device of the present invention, when the moving speed or rotational speed of the movable operation unit is higher than a predetermined high-speed reference speed, the adjustment set value determined by the set value determining unit is a predetermined high value. When the flow rate set value or the high temperature set value is exceeded, the drive speed determination unit determines the valve body drive speed to be 0, and stops the valve body of the flow rate adjustment valve or the hot and cold water mixing valve. Thereby, when the moving speed or the rotational speed of the movable operation unit is higher than the high-speed reference speed, it is possible to prevent the adjustment setting value of the flow rate or the temperature from being excessively larger than the adjustment setting value desired by the user. Thus, the operation of the faucet device can be brought close to the operation desired by the user, and the operation feeling of the user can be improved.

  In the faucet device according to the present invention, preferably, the valve body drive speed is proportional to the moving speed or the rotational speed.

  In the faucet device according to the present invention, it is preferable that the drive speed determination unit maintains the valve body drive speed at 0 regardless of the moving speed or the rotation speed of the movable operation unit after determining the valve body drive speed to 0. Then, after the moving speed or the rotational speed of the movable operation unit becomes zero, the valve body driving speed is determined so that the valve body driving speed is increased again as the moving speed or the rotational speed is increased.

  In the faucet device configured as described above, immediately after the drive speed determining unit determines the valve body drive speed to 0, while the moving speed or the rotational speed is smaller than the high speed reference speed, it is still moving (that is, When the moving speed or rotational speed exceeds 0), it is estimated that the user does not want to increase the flow rate or temperature adjustment setting value, and the valve body is driven regardless of the moving speed or rotational speed of the movable operation unit. Maintain speed at zero. Then, after the moving speed or rotational speed of the movable operation unit becomes zero, it is estimated that the user is allowed to increase the flow rate or temperature adjustment set value by operating the movable operation unit, and the moving speed or The valve body drive speed is determined so as to increase the valve body drive speed as the rotational speed is increased. Thus, the operation of the faucet device can be brought close to the operation desired by the user, and the operation feeling of the user can be improved.

  In the faucet device according to the present invention, preferably, the adjustment set value determined by the set value determining unit is larger than a predetermined high flow rate set value or a high temperature set value, and the moving speed or rotation of the movable operation unit. When the speed is greater than a predetermined low speed reference speed, the drive speed determination unit determines the valve body drive speed to be zero.

  In the faucet device according to the present invention, the adjustment range larger than the high flow rate set value or the high temperature set value is narrow, and therefore the moving speed or rotational speed of the movable operating unit within the range is determined by the movable operating unit. However, if the speed is higher than the reference temperature at low speed, the drive speed determination unit will operate the valve body drive speed. Is set to 0, and the valve body of the flow rate adjusting valve or the hot and cold water mixing valve is stopped. When the adjustment set value is equal to or higher than the high flow rate set value or the high temperature set value, it can be prevented that the adjustment set value becomes a large adjustment set value that is not desired by the user.

  In the faucet device, preferably, the ratio of the valve body driving speed to the moving speed or the rotational speed is higher than that when the flow rate or temperature adjustment set value is less than the high flow rate set value or the high temperature set value. The adjustment set value is larger when it is higher than the high flow rate set value or the high temperature set value.

  In the faucet device configured as described above, when the adjustment set value is larger than the high flow rate set value or the high temperature set value and the moving speed or the rotational speed is smaller than the low speed reference speed, the user can It is estimated that it is desired to positively change the adjustment set value while recognizing that the adjustment set value is higher than the high flow rate set value or the high temperature set value. The ratio of the valve body driving speed to the moving speed or the rotational speed is such that the flow rate or temperature adjustment set value is higher than the high flow rate set value or the high temperature set value. Alternatively, the user-friendliness can be improved by increasing the value higher than the high temperature set value.

  The faucet device according to the present invention preferably has a notifying unit for notifying that the valve body driving speed is maintained at 0 regardless of the moving speed or the rotating speed of the movable operating unit.

  In the water faucet device configured in this way, the user can recognize that the valve body drive speed is 0, so that it is possible to prevent misidentification that the water faucet device has failed when the valve body does not operate. it can.

  As described above, according to the faucet device of the present invention, the operation of the faucet device can be brought close to the operation desired by the user, and the operation feeling of the user can be improved.

  Exemplary embodiments of the invention will now be described with reference to the accompanying drawings.

  FIG. 1 is a schematic view of a faucet device. FIG. 2 is a schematic view of a faucet function unit of the faucet device. FIG. 3 is a cross-sectional view of the movable operation unit of the faucet device.

  As shown in FIG. 1, a faucet device 1 according to the present invention includes a wash counter 4 in which a wash bowl 2 is disposed, a faucet body 6 having a water discharge port 6 a provided to discharge water into the wash bowl 2, and It has two movable operation parts 8 and 10 provided in the wash counter 4 near the wash bowl 2, and a faucet function part 12 (see FIG. 2) arranged below the wash counter 4. One movable operation unit 8 is for performing water discharge from the water discharge port 6a of the faucet body 6 and switching the water stop and adjusting the water discharge flow rate, and the other movable operation unit 10 adjusts the water discharge temperature. Is to do.

  As shown in FIG. 2, the faucet function unit 12 is connected between a hot water mixing valve 16 and a hot water mixing valve 16 connected to the hot water supply pipe 14a and the water supply pipe 14b, and between the hot water mixing valve 16 and the water outlet 6a. A flow rate adjusting valve 18 and a control unit 20 for controlling the faucet function unit 12 are provided.

  The control unit 20 includes an input interface for inputting signals from the movable operation units 8, 10 and the like, a memory for storing a control program and control data, a microprocessor for executing the control program, a hot and cold mixing valve 16 and a flow rate adjusting valve. 18 has an output interface (not shown) for outputting a signal.

  The valve body 16b of the hot / cold water mixing valve 16 is connected to the motor 16a and is electrically driven by the control unit 20 based on the operation of the movable operation unit 10 for adjusting the water discharge temperature. 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.

  The valve body 18b 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. Further, the rotary encoder 32 is fixed to the plate 32b by a nut 32a, and the plate 32b is expanded by a nut 34 that is screwed into the female screw portion 26e so that the rotary encoder 32 is positioned in the through hole 26c. 26d is fixed. The operation handle 28 includes a circular upper wall 28a, a side wall 28b extending downward from the periphery of the upper wall 28a, and a shaft portion 28c extending downward from the center of the upper wall 28a. The rotary shaft 32d is connected. An annular packing 36 is preferably provided between the operation handle 28 and the operation portion main body 26. 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 the rotation speed of the operation handle 28 of the movable operation units 8 and 10 in real time, and a flow rate adjustment valve 18 and a hot and cold mixing valve as the rotation speed is increased. 16 has a drive speed determination unit 42 that determines the valve body drive speed and a set value determination unit 44 that determines a temperature adjustment set value based on the rotation speed. . Further, the notification unit 46 is connected to the control unit 20. The notification unit 46 may be, for example, a light that lights or blinks, or may be a buzzer.

  The operation detection unit 40 is configured to detect the rotation speed of the operation handle 28 of the movable operation units 8 and 10 based on the pulse signal from the rotary encoder 32. Further, the operation detection unit determines whether the rotation direction of the operation handle 28 of the movable operation units 8 and 10 is an increasing direction (clockwise) that increases 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.

  The drive speed determination unit 42 increases the valve body drive speed of the hot and cold water mixing valve as the rotation speed of the operation handle 28 is increased in both cases where the rotation direction of the operation handle 28 is an increase direction and a decrease direction. Thus, the valve body drive speed is determined. The valve body drive speed is preferably proportional to the rotation speed.

  For example, the set value determination unit 44 determines the flow rate or temperature adjustment set value by adding a temperature change corresponding to a value obtained by multiplying the rotational speed by time to the current temperature adjustment set value.

  Next, the operation of the control unit 20 will be described. Since the case where the hot water mixing valve 16 is controlled by the movable adjustment unit 10 for adjusting the discharged water temperature and the case where the flow rate adjusting valve 18 is controlled by the movable adjusting unit 8 for adjusting the discharged water flow rate are the same, only the former will be described.

  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 speed and rotation direction of the operation handle 28 from the number, phase, and time of pulses. Next, the drive speed determination unit 42 determines the valve body drive speed. This determination method will be described later in detail. Next, the adjustment value determination unit 44 determines a new temperature adjustment setting value by adding a temperature change corresponding to a value obtained by multiplying the rotational speed by time to the current temperature adjustment setting value. On the other hand, the control unit 20 drives the valve body 16b of the hot / cold water mixing valve 16 at a valve body drive speed via the motor 16a. 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.

  Next, how to determine the valve body drive speed in the drive speed determination unit 42 will be described. When the rotation direction of the operation handle 28 is a decreasing direction, the valve body drive speed is determined so as to increase the valve body drive speed as the rotation speed of the operation handle 28 is increased. The valve body drive speed is preferably proportional to the rotation speed. When the rotation direction of the operation handle 28 is an increasing direction, the valve body drive speed is determined so as to increase the valve body drive speed as the rotation speed of the operation handle 28 is increased. The valve body drive speed is preferably proportional to the rotation speed.

  When the rotation direction of the operation handle 28 is the increasing direction, the rotation speed is higher than the predetermined high-speed reference speed VH2, and the temperature adjustment setting value determined by the setting value determination unit 44 is determined in advance. When it becomes equal to or higher than the set high temperature value (for example, 40 ° C.), the drive speed determination unit 42 determines the valve body drive speed to be 0, and the motor 16a of the hot / cold water mixing valve 16 Stop.

  By this operation, it is possible to prevent the adjustment set value of the flow rate or temperature from becoming too larger than the adjustment set value desired by the user.

  Thereafter, the drive speed determination unit 42 maintains the valve body drive speed at 0 regardless of the operation handle rotation speed, and after the rotation speed becomes 0, increases the valve body drive speed as the rotation speed is increased again. Thus, the valve body drive speed is determined. While the valve body drive speed is maintained at 0 regardless of the rotation speed of the operation handle, the notification section 46 preferably informs the user of this fact.

  By this operation, water discharge at a temperature higher than the high temperature set value can be performed according to the desire of the user.

  When the rotation direction of the operation handle 28 is the increasing direction, when the rotation speed is lower than the predetermined high-speed reference speed VH2, the temperature adjustment setting value determined by the setting value determination unit 44 is determined in advance. Even when the temperature is higher than the high temperature set value, the drive speed determination unit 42 determines the valve body drive speed so as to increase the valve body drive speed as the rotational speed is increased. However, when the adjustment setting value determined by the setting value determination unit is larger than the high temperature setting value and the rotation speed of the operation handle 28 is larger than the predetermined low speed reference speed VH1, the driving speed determination unit. 42 determines the valve body drive speed to 0, and stops the valve body 16b of the hot and cold water mixing valve 16.

  By this operation, even when the user operates the operation handle at a low speed, it is possible to prevent the user from unintentionally setting a large adjustment set value.

  As a modified example, when the rotation direction of the operation handle 28 is an increasing direction, when the valve element drive speed determined by the drive speed determination unit 42 is proportional to the rotation speed of the operation handle 28, the valve element drive with respect to the rotation speed is performed. The speed proportional coefficient (that is, the ratio of the valve drive speed to the rotational speed) should be larger when the temperature adjustment set value is higher than the high temperature set value than when the temperature adjustment set value is less than the high temperature set value. May be.

  By this operation, even if the operation handle 28 is operated very slowly in order to make the temperature higher than the high temperature set value, the valve drive speed becomes relatively large, and the adjustment set value of the water discharge temperature increases. User convenience can be improved.

  Next, with reference to FIG.4 and FIG.5, the operation example which adjusts water discharge temperature is demonstrated. In these figures, v1 to v4 represent the rotational speed of the operation handle 28, VH1 and VH2 represent the low speed reference speed and the high speed reference speed, respectively, and the relationship 0 <v1 <v2 <VH1 <v3 <VH2 <v4. It is in. Further, the valve body driving speeds corresponding to v1 to v4 are represented by b1 to b4, and these valve body driving speeds have a relationship of b1 (b1 ′) <b2 (b2 ′) <b3 <b4.

  FIG. 4 is a time chart illustrating a first operation example. FIG. 4B shows the rotation angle of the operation handle 28 for adjusting the water discharge temperature, and FIG. 4A shows the corresponding water discharge temperature adjustment set value.

  As shown in FIG. 4B, in steps S1 to S4, the operation handle 28 is rotated twice so as to increase the water discharge temperature, and the rotation of the operation handle 28 is stopped twice. The rotation speed in step S1 is v1, and the rotation speed in step S2 is v4. Next, in steps S5 to S6, the operation handle 28 is rotated at the respective rotation speeds v2 and v4 so as to decrease the water discharge temperature, and in step S7, the rotation of the operation handle 28 is stopped. Next, after the operation handle 28 is rotated at the rotation speeds v2 and v3 so as to increase the water discharge temperature in steps S8 and S9, the rotation of the operation handle 28 is stopped in step S10, and the water discharge is performed in step S11. It is rotated at a rotational speed v4 so as to reduce the speed, and the rotation of the operation handle 28 is stopped in step S12. Next, in steps S13 and S14, the operation handle 28 is rotated at the rotation speeds v4 and v1 so as to increase the water discharge temperature. In step S15, the rotation of the operation handle 28 is stopped. In step S16, the operation handle 28 is stopped. Is rotated at a rotational speed v1 so as to increase the water discharge temperature.

  As shown in FIG. 4 (a), in steps S1 to S3a, since the adjustment set value of the water discharge temperature is less than the high temperature set value, the valve body drive speed is b1, 0 corresponding to the rotational speeds v1, 0, v4. , B4, and the adjustment setting value of the water discharge temperature reaches the high temperature setting value. In step S3b, since the rotational speed v4 is larger than the predetermined high-speed reference speed VH2, when the adjustment value of the water discharge temperature is equal to or higher than the high temperature set value, the valve body drive speed becomes 0 and the adjustment of the water discharge temperature. The set value is maintained at the high temperature set value. In step S4, since the rotational speed is zero, the valve body drive speed remains zero. In steps S5 to S7, since the water discharge temperature is decreased, the valve body drive speed changes to b2, b4, 0 corresponding to the rotation speeds v2, v4, 0, and the water discharge temperature adjustment set value is 0. Become.

  In step S8a, since the adjustment setting value of the water discharge temperature is less than the high temperature setting value, the valve body driving speed is b2 corresponding to the rotation speed v2. Next, in step S8b, since the rotational speed v2 is smaller than the predetermined high-speed reference speed VH2, the valve element drive speed remains b2 even if the discharge temperature adjustment set value is equal to or higher than the high temperature set value. The adjustment setting value of the water discharge temperature is larger than the high temperature setting value.

  In step S9, since the rotational speed v3 is higher than the predetermined low speed reference speed VH1, the valve body drive speed becomes 0, and the adjustment value of the water discharge temperature does not change.

  In step S10, since the rotational speed is zero, the valve body driving speed remains zero. In Steps S11 to S13a, the adjustment set value of the water discharge temperature is less than the temperature decreasing direction or the high temperature set value, so that the valve body drive speed changes as b4, 0, and b4. In step S13b, since the rotational speed v4 is greater than the predetermined high-speed reference speed VH2, when the water discharge temperature adjustment set value is equal to or higher than the high temperature set value, the valve body drive speed becomes 0 and the water discharge temperature adjustment. The set value is maintained at the high temperature set value. Thereafter, in step S14, the valve body drive speed is maintained at 0 regardless of the rotation speed. In S15, the rotational speed becomes 0, the valve body drive speed is increased, and the adjustment value of the water discharge temperature can be changed. In step S16, since the rotational speed v1 is smaller than the predetermined high-speed reference speed VH2, the adjustment setting value of the water discharge temperature is equal to or higher than the high temperature set value, but the valve body drive speed is maintained at b1, and the discharge water temperature The adjustment set value is larger than the high temperature set value.

  FIG. 5 is a time chart showing a second operation example. FIG. 5B shows the rotation angle of the operation handle 28 for adjusting the water discharge temperature, and FIG. 5A shows the corresponding water discharge temperature adjustment set value. FIG. 5B is the same as FIG.

  Further, the change in the water discharge temperature set value shown in FIG. 5A is that the valve body drive speed is b2 ′ (> b2) in step S8b, and the valve body drive speed is b1 ′ (> b1) in step S16. The time chart shown in FIG. 4A is the same as that shown in FIG. As in the second operation example, the proportional coefficient of the valve body drive speed with respect to the rotation speed is larger when the temperature adjustment set value is equal to or higher than the high temperature set value than when the temperature adjustment set value is less than the high temperature set value. It may be.
