[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a valve device.

[0002]

2.

An eddy current governor that regulates the rotation and a plurality of cams that are transmitted with the rotation of the hoisting shaft that rotates by the release force of the spring and rotate, and have cam shapes corresponding to the respective operation times of the plurality of valve mechanisms. A switching timer unit for manual operation is disclosed.

[0003] JP-A-2000-309974, JP-A-200
0-309969 and JP-A-2000-309968,
An opening and closing valve is provided in each of the plurality of flow paths to mechanically open and close the valve body, and a cam for transmitting a mechanical operating force for opening and closing each valve body is provided for each of the opening and closing valves. A motor is provided to apply a mechanical operating force to each opening / closing valve through a cam, and the output timing of the mechanical operating force from the motor to each cam or the like has a predetermined time lag for each cam or the like. A channel switching unit having a simple structure that is configured and provided with a manual operation unit that can directly drive the drive shaft of a motor directly and manually and that can be operated both electrically and manually is disclosed.

[0004]

A valve device having both a manual operation and an electric operation has a manual operation portion located near the valve device in order to enhance the convenience of the user and simplify the internal structure. The electric operation unit is provided separately from the valve device so that it can be operated from a remote place by a remote controller or the like.
However, since these have different operating principles and objectives, the internal design of the device is different, and when viewed from the user, the operating time, etc., when operating with the manual operation unit and when operating with the electric operation unit is different. The operating conditions are different and you may feel uncomfortable. In addition, when this valve device is used in a water discharging device or the like, since the water discharging state is greatly different depending on which operation is performed, especially for a user who is unfamiliar with the operation, the user may generate undesired water splash, Even when water is stored in the container, it may be inadvertently overflowed, which may impair the convenience of the user.

[0005] Further, in a valve device of the type in which the operation is normally performed electrically and the manual operation is performed only at the time of a power failure or the like, the time setting is performed because the manual operation itself is designed on the premise of an emergency backup operation. There was a problem that the start and stop of water flow were not performed reliably, such as forgetting to stop water after water flow due to lack of normal operation. In addition, it is necessary to hide the manual operation unit in the apparatus so that the operation is not performed during normal use, and to provide a special mechanism for preventing an erroneous operation.

SUMMARY OF THE INVENTION An object of the present invention is to provide a valve device and a valve operating time setting method of the valve device for reliably performing water flow that meets the user's intention, whether manual operation or electric operation. That is.

[0007]

Means, actions and effects for solving the problem.
Has a time setting means for setting the water flow time,
A valve device that performs water flow control by selectively using an operation force based on a manual operation and a motorized driving force, wherein the time setting means independently controls the water flow time by the manual operation and the water flow time by the electric motor independently. Can be set. If the time can be set independently for manual operation and electric operation, it is possible to set the optimal time for each operation and set the washing mode according to the purpose and application, and it is easy to operate with almost the same operating time Can be set to By setting the operation time with the electric operation to be substantially the same as the operation time of the manual operation, the user may feel uncomfortable or confused whether the electric operation is performed or the manual operation is performed. This prevents accidents such as splashing or carelessly overflowing water.

According to a second aspect of the present invention, a power supply means for supplying power, a motor driven directly or indirectly by the power supplied by the power supply means, and a motor driven by the motor to open and close a valve. A first valve element for starting or stopping water, an armature control means for communicating the power supply means with the armature to turn on / off the power supply, and driving the armature control means so that the armature operates for a predetermined time. Timer means, an operating means, a second valve element which is driven directly or indirectly by an operating force applied from the operating means to start or stop water flow by opening and closing the valve, and a driving speed of the second valve element. Since there is provided speed setting means for decelerating and setting the speed to a predetermined speed, time control can be performed reliably and accurately. Further, even when aging or the like occurs, the time set value does not fluctuate, and high reliability and stable water flow can be obtained for a long time. Furthermore, since the time can be set with a simple configuration, the time can be arbitrarily set according to the design conditions, purpose, or application, and the design can be easily changed. In addition, since the time can be set independently, the degree of design freedom is high, and a manual and an electric motor can be freely laid out. Further, it is possible to easily set substantially the same operation time.

According to the third aspect of the present invention, the timer means is configured to be able to change the time set value, so that the operation time of the electric operation can be arbitrarily set, and the time can be adjusted with a simple configuration. In addition, since the time adjustment of the electric operation can be easily configured as compared with the mechanical time adjustment by the manual operation unit, it is particularly suitable for fine adjustment of the set time.

According to the present invention, the timer means has a plurality of selectable different time setting values. Therefore, if the assembling tolerance and design variation of the manual operation unit are grasped in advance, strict time adjustment can be performed. At least, the time can be easily adjusted by selecting the closest one from the set values. Further, changes at the installation site or the like are easy.

In the present invention, the number of electric time setting values is larger than that of manual operation. In the case of electric operation, there is no need to transmit the driving force directly from the activation unit operated by the user, and therefore, the electric activation unit can be installed at any position. In addition, since it is easy to provide a plurality, even if the set value is increased, the apparatus does not become large or the configuration is not complicated, and the time can be set in accordance with the user's request. Further, since the variation of the set value of the electric timer is very small compared to the manual mechanical timer, even if the time set value is set to a large value and the set value is slightly different, the desired valve operation is performed. Can be performed accurately and with good reproducibility.

According to the present invention, the electric time setting value has a smaller set value than the manual time setting value. Compared with a manual mechanical timer, an electric timer has less variation in the set value, and even if the time set value is reduced, the influence of the time variation due to the error is small. In addition, since the time set value by motor is very easy to change, the time set value can be set small according to the function limit of the valve device, and the maximum water saving effect without impairing the original function of the valve device. Get easily.

According to a seventh aspect of the present invention, there is provided a water flow physical quantity control means for controlling a physical quantity such as a water flow rate, a water flow cycle, and a water flow time in conjunction with the time setting means. Enables not only simple water stoppage but also complicated water flow control, and has a time setting that is accurate and easily recognizable by the user, so operation is reliable and even if you are unfamiliar with handling, you may be puzzled even if you are unfamiliar with handling There is no.

[0014] In claim 8, the water flow physical quantity control means is a quantitative means for controlling the flow rate of water flow to a substantially constant amount. In the present invention, the time can be accurately controlled regardless of whether the operation is electric operation or manual operation, and furthermore, since it has the same time set value, the fixed amount water stoppage function for making the flow rate per operation approximately constant is provided. It can be easily configured. By providing the constant flow valve, it is not necessary to provide a special mechanism for controlling the amount of water, so that the apparatus can be made compact.

According to the ninth aspect, the physical quantity control means has a common structure between the manual operation and the electric operation, and thus has an operation mechanism in the manual operation and an operation mechanism in the electric operation. Nevertheless, the device itself can be very small. Further, since the configuration is simplified, the reliability is high, and it is not necessary to newly design each time when the time is set manually and electrically.

According to a tenth aspect of the present invention, there is provided a main valve which communicates with the first valve body and / or the second valve body to perform opening / closing driving of a larger flow rate. Direct opening / closing drive of water passage requires a large opening / closing drive torque of the valve. However, when a margin torque for performing accurate time control is also taken into account, the entire apparatus becomes very large. Therefore, by using the first valve body and / or the second valve body as a control valve for controlling the opening and closing of the main valve, the size of the valve device itself can be either one of the manual operation and the electric operation, but the size of the valve device itself is one. The size can be made substantially the same as in the case of. In particular, by using the second valve body that is manually operated as the control valve of the main valve, the driving force of the valve operation can be significantly reduced. This can reduce the set values of operating force and driving force during manual operation,
Excellent operability.

In the eleventh aspect, the second valve body is a first valve body. To set the valve control time accurately,
It is necessary to take into account the response delay of the valve body. When setting the same time for manual water supply and electric water supply,
It is necessary to add a response delay of the valve to these time setting values in advance. For example, when a completely different valve mechanism is used for manual operation and electric operation, it is necessary to reflect the response delay of each valve to each set time. However, if the second valve body and the first valve body are a common valve, the response delay of the valves is completely the same, so that the set time of both can be made substantially the same, and the design, inspection, confirmation, etc. of the device Can be easily done.
Naturally, further miniaturization of the valve device itself is also feasible.

According to a twelfth aspect, the faucet device is provided with the above-described valve device.

In a thirteenth aspect, a toilet device is provided with the above-described valve device. In toilet flushing, it is required to reduce the amount of water used per flush. However, if the amount of cleaning water is unnecessarily reduced, the original cleaning function may be reduced. In particular, when the flushing water amount is gradually reduced in the same toilet apparatus, the flushing function may suddenly decrease when a certain threshold value is exceeded. By setting substantially the same water flow time for manual operation and electric operation, it is possible to have the same cleaning function whether the operation is manual or electric and, of course, the substantially same set value does not exceed this threshold value. By setting the range in advance, the maximum water saving effect can be always obtained and a stable cleaning function can be easily obtained.

According to the present invention, the valve operation time in manual operation and the valve operation time in electric operation can be set independently of each other, and the valve element driven by the operation force based on the manual operation and the electric motor drive. An operating time setting method of a valve device that performs water flow by selectively using a valve body,
The operation time of the valve body is determined so that the water flow time by manual operation and the water flow time by electric motor are substantially the same. In consideration of the response characteristics and the operation delay time between the valve element driven by the manual operation and the valve element driven by the electric power so that the water passage time in the manual operation and the water passage time in the electric operation are substantially the same. By determining the operation time of the valve element, a valve device that is excellent in operability and can be easily used by an unskilled user can be configured very simply.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1, 15 (a) and 15
(B), FIG. 16, FIG. 17, and FIG. 18 are schematic views of the manual operation unit in the first embodiment of the present invention. Manual operation unit 20
Are provided with valve bodies 4 and 7. Water inlet 5 in valve body 4
The valve body 4 is formed by water supplied from the valve body and the valve seat facing the valve 3 of the movable body, and water is discharged from the water outlet 2 with the opening and closing of the valve body 4. Similarly, the valve element 7 is configured such that water is supplied from the water inlet 8, the valve element 7 is formed by the valve seat of the movable body 6 and the opposite valve seat, and water is discharged from the water outlet 9 as the valve element 7 opens and closes. It has become. Each of the valve bodies 4 and 7 is configured to be closed when not in operation. Note that the valve element 7 has a configuration in which the pressure resistance is increased in order to control the primary pressure.

The operation principle of the manual operation section 20 will be described in the order of manual operation. When the operating means 19 is rotated clockwise or a pressing operation is performed, the first gear 18 and the first cam 17 directly connected to the operating means 19 rotate. When not actuated, the valve 6 is pressed by the primary pressure against the opposing valve seat and the valve body 7
Is closed. With the rotation of the operating means 19, the first cam 17 drives the valve 6 in the opening direction, and when the rotation angle reaches a predetermined rotation angle, the valve 6 is opened. In synchronization with this, the first gear 18 also rotates, and the second gear 15 rotates counterclockwise. Since the clutch 14 is directly or integrally formed with the second gear 15 and the urging means 16 is directly connected thereto, the clutch 14 is disengaged while the second gear 15 is rotating counterclockwise. The driving force is transmitted only to the urging means 16, and the driving energy is stored.

The operating means 19 is provided with a stopper (not shown), which restricts the operation of the operating means 19 when a predetermined rotation angle β or a predetermined operation amount is reached, so that no further operation can be performed. ing. The drive energy accumulated in the urging means 16 at the stage when the stopper is reached is maximized. At this time, when the operating means 19 is released, the clutch 14 is engaged and the driving force of the urging means 16 is transmitted to the second cam 13. It is to be noted that the operating means 19 is set to a predetermined rotation
Alternatively, the clutch 14 is not engaged when the operation is not performed for a predetermined amount or more. Even when the operation means 19 is released, the second cam 13 is not driven and the operation means 19, the first gear 18, the first cam 17 and the valve 6 return to the initial position.

The clutch 14 is configured to be engaged when the rotation angle θ of the operating means 19 is set to a position of α <θ ≦ β and disengaged. In this case, the second angle is (θ−α). There is an idle running section in which the cam 13 is not driven. Second cam 13
Has a third gear 12 and a third cam 10 directly connected or integrally formed. Both the first cam 17 and the second cam 13 can drive the valve 6, and when the clutch 14 is engaged and the second cam 13 is driven, the first cam 17 rotates counterclockwise. The valve 6 starts to be driven in the closing direction, but the second cam 13 keeps the valve 6 open instead. Therefore, the valve 6 keeps the open state until the manual operation 20 stops operating. The third gear 12 drives the speed setting means 11 and drives the valve body driving body 21 at a substantially constant speed by the braking force generated by the speed setting means 11. Valve drive 21
Are constituted by a second cam 13, a third gear 12, and a third cam 10, and are integrally formed or directly connected to each other.
The third cam 10 drives the valve 3 to control the opening and closing of the valve element 4.
With the driving of the valve body driving body 21, the third cam 10 drives the valve body 4 to open to start water flow after a predetermined time has elapsed, and further closes the valve body 4 after a predetermined time to stop water flow. . Further, after a predetermined time, the second cam 13 closes the valve body 7 to stop all water flow. The valve body driving body 21 continues idling for a predetermined time after the closing drive of the valve body 7 in order to surely perform water stoppage in consideration of mechanical built-in tolerance and design tolerance. When the urging unit 16 returns to the initial position, the manual operation unit 20 stops and enters the initial state.

Further, by directly driving the valve element 7 by the operating means 19 and the first cam 17, even when the supply water pressure is high, the valve element 7 can be reliably driven to open, and the primary pressure is directly applied. Since the driving of the speed setting means 11 is started after the valve element 7 is previously opened, the driving load can be made uniform and reduced. Therefore, the set load of the urging means 16 can be reduced, and the operating force can be reduced. Can be reduced.

Since the valve body driving body 21 is adjusted to a substantially constant speed and driven based on the driving energy stored in the urging means 16 as described above, the second cam 13 and the third cam 1 are driven.
With the structure of 0, the closing of the valve body 7 and the opening and closing of the valve body 4 are performed at predetermined precise timing, and the reliable water flow control by the valve body 7 and the valve body 4 is realized. Note here, after a predetermined time T ₁ of the valve body 7 is open drive, the valve element 4 is open drive, then the valve body 4 is closed driven after the predetermined time T _2, the valve body 7 after a further predetermined time T ₃ Is driven to close. That is, the total operation time T of the valve elements 4 and 7 is T = T ₁ + T ₂ +
Represented by T _3, T, is accurately managed and controlled by T _1, T 2, _T any time even speed setting means 11 for _3.

Arrows shown in FIGS. 15A, 16, 17, and 18 indicate the respective rotation directions after the operating means 19 is opened. FIG. 15 (b)
Shows an engagement groove of the second cam 13 which engages with the clutch 14 according to the rotation direction.

FIGS. 2 and 3 are schematic diagrams of the speed setting means 11. FIG. 2 is a sectional view of the speed setting means 11,
FIG. 3 is an external view showing the inside from the top. The speed setting means 11 causes the drive unit 23 to engage a gear (not shown), and drives the drive unit 23 via this gear to generate a predetermined braking force. The driving force applied to the driving unit 23 is transmitted to the gear train 30. The gear train 30 includes a driving unit 23, a first speed increasing gear 24, a second speed increasing gear 25, a third speed increasing gear 26, a fourth speed increasing gear 27, and a rotor gear 37,
The driving force is transmitted to the rotor gear 37 in order from the first speed increasing gear. The rotor 28 and the rotor gear 37 are integrally formed, so that even when the rotor gear 37 rotates at a high speed, the rotor 28 can be reliably driven without being affected by the inertia of the rotor 28.

A permanent magnet 31 is fitted into the rotor 28, and the permanent magnet 31 rotates simultaneously with the rotation of the rotor 28. A first yoke 32 and a second yoke 33 are provided on the outer periphery of the permanent magnet 31 at a predetermined separation distance. The first yoke 32 and the second yoke 33 are obtained by bending the surface of a soft iron plate with a plating process into a predetermined shape. A copper wire is wound around the first yoke 32 and the second yoke 33 to form a first coil 34 and a second coil 35. With the rotation of the permanent magnet 31, the first coil 34 and the second coil 35 are subjected to electromagnetic conversion to generate an electromotive force. The end of each winding is connected to an electrode (not shown) so that these electromotive forces can be extracted to the outside, so that the electromotive force generated by electromagnetic conversion can be extracted to the outside of the speed setting means 11. . Although a coil body including a plurality of coils and a yoke is used here, a single coil may be used according to a required torque load.

The section from the drive section 23 to the rotor 28 is a speed increasing section, and constitutes a speed increasing device. The speed increase ratio between the drive unit 23 and the rotor 28 is set to approximately 16 times. This allows the rotor 28 to rotate at a high speed even when the drive unit 23 is rotated slowly, so that a large electromotive force can be extracted from the electrode unit and the braking force can be increased. Therefore, the speed setting means 11 can be configured very small. it can. It is desirable that the speed increase ratio is appropriately set to an optimum value according to design conditions such as a required load torque during rotation, a load torque at startup and a rotation speed.

The gear train 30 is configured to be sandwiched between the lid 29 and the fixing plate 38, and each gear is perforated at the center and penetrated by a stainless steel pin. The gear train 30 is rotatably positioned and fixed by inserting or fitting a pin into a recess or opening provided in the lid 29 and the fixing plate 38. Drive unit 23
Is taken out through the opening of the lid 29,
9 is provided with a bearing 36. Since the bearing 36 is provided in the middle of the path for transmitting the driving force,
It is possible to effectively prevent the condensed water from entering along the transmission path. In particular, since a speed increasing device that rotates at a high speed is provided, the operation becomes unstable due to the intrusion of the dew condensation water, or the electric leakage can be prevented. Further, the gear train 30 and the bearing 36 are oiled with grease or the like in order to facilitate high-speed driving and prevent adverse effects due to moisture and water droplets. The bearing 36 also prevents these oils from leaking.

The permanent magnet 31 is a cobalt ferrite magnet having a high coercive force, and is magnetized substantially uniformly in the circumferential direction. Here, the S pole and the N pole are equally spaced in the circumferential direction by 6 respectively.
A 12-pole configuration in which poles are alternately used is used. In addition, the composition of the permanent magnet 31 may include neodymium, samarium, cobalt, chromium, and the like. By using a material having a high coercive force, a small and high braking force is exhibited. Also,
Multipolar anisotropic magnets can also be used.

Thus, by using the manual operation unit 20 as shown in the present embodiment, the opening and closing drive of the valve body 4 and the valve body 7 can be performed at accurate timing.

Further, the manual operation unit 20 can be used in the following manner. Speed setting means 11
It is also possible to take out the output from the driving unit 23 by applying the driving power to. That is, by driving the speed setting means 11 at a predetermined speed, it becomes possible to drive the valves 3 and 6 to control the valve elements 4 and 7 in the same manner as in the manual operation. With such a configuration, it is possible to operate using a common unit regardless of whether it is manual or electric.

FIG. 9 shows a control block diagram for enabling the above operation. The control unit 101 includes a memory 102
, The controller 106, the driver 103, the electric load 108, the switch 104, and the operation detecting unit 10.
7 and a timer 109. The controller 106 includes a CPU, a gate array, a programmable controller, a logical operator, and the like. The coil body of the speed setting unit 11 and the starting unit 105 are connected.
Although the speed setting means 11 has a first coil 34 and a second coil 35, only one of them is shown here. The memory 102 includes a RAM, a ROM, a flash memory, a magnetic recording medium, an optical recording medium, and the like. It is remembered. Driver 103 is controller 1
Based on the instruction from 06, electric power for driving the speed setting means 11 as an actuator is supplied.

The speed setting means 11 usually includes the electric load 10
8 is connected, and is configured such that a braking force proportional to the rotation speed of the speed setting means 11 is applied by consuming the electromotive force generated from the speed setting means 11 when a manual operation is performed. The means 11 is driven at a predetermined rotation speed. The operation detecting unit 107 is connected to the coil of the speed setting unit 11 and detects the voltage applied to the coil or the generated electromotive force. When a manual operation is being performed, the operation detection unit 107 can measure the electromotive force of the speed setting unit 11, and when a predetermined frequency and voltage are detected, the controller determines that the speed setting unit 11 is operating manually. 106 is recognizable. Switch 1 for manual operation
04 is in the initial position and connects the speed setting means 11 and the electric load 108, so that the speed setting means 11 generates a predetermined braking force. In this case, even if the activation unit 105 is activated, the controller 106 can recognize that the speed setting unit 11 is already operating by manual operation. After detecting the inactivity of the setting means 11, the speed setting means 1
Since the control procedure can be set so as to activate the driver 103 so as to drive the motor 1, a reliable operation can be performed with high reliability without imposing an excessive load on the speed setting unit 11.

The switch 104 indicates a normal standby position, and connects the speed setting means 11 to the electric load 108. This is preferable because the operating speed is immediately set to a predetermined value when a manual operation is applied. Alternatively, the operation detection unit may directly detect the operation of the cam or gear of the manual operation unit 20 or the operation of the speed setting unit 11. For this, an encoder, a Hall element, photoelectric detection and the like can be used. As the switch 104, not only a mechanical switch such as a relay but also a diode switch and a transistor switch can be used. Switch 1
A noise removing unit such as a coupling capacitor or a photoelectric coupler may be provided in the connection path from the signal line 04 to the operation detection unit 107 in order to prevent malfunction of noise.

This configuration is preferable because, for example, even if the control unit 101 becomes inoperable due to a power failure or the like, the operation state by manual operation is not affected. Further, the control unit 101 is set to the normal standby mode, and when the activation unit 105 is activated, when the driver 103 is driven, or by a detection signal provided from outside such as a human body detection unit (not shown), the control unit 101 is activated. If a control procedure is determined in advance so as to switch to the operation mode, power consumption during standby can be minimized and the energy saving effect is high.

When the operation by electric power is selected, the switch 10 is controlled based on an instruction from the controller 106.
4 separates the speed setting means 11 and the electric load 108,
By connecting the speed setting means 11 and the driver 103 instead, it becomes possible to supply drive power for using the speed setting means 11 as an actuator. Here, the operation detection unit detects a signal in which the power supplied from the driver 103 and the electromotive force generated in the coil body by driving the speed setting unit 11 are overlapped. Since the power signal supplied from the driver 103 can be easily obtained by the controller 106, the difference between the power signal and the superimposed signal is calculated so that the controller 106 generates the back electromotive force synchronized with the rotation frequency generated by the speed setting means 11. Since the signal is obtained, it is possible to monitor the speed at which the speed setting means 11 or the manual operation unit 20 is driven even during the electric operation. This also occurs when the controller 106 is driven at a speed higher than a predetermined speed by applying both the manual driving force and the electric driving force in a case where a manual operation is performed during the electric operation. Detects that a manual operation has been performed,
An instruction to switch to the electric load 108 can be issued from the driver 103 to the switch 104. Thereby, the operation is immediately switched from the electric operation to the manual operation, and the valve bodies 4 and 7 are driven at a predetermined operation speed.

Here, a variable resistor is used for the electric load 108. This may be a fixed type, but it is possible to arbitrarily adjust the operating speed of the speed setting means 11 in the case of manually operating by making it variable.
An array unit that prepares a plurality of electrical loads such as resistors in advance to enable adjustment, and sets a plurality of selectable load amounts by connecting or disconnecting them in series or in parallel It may be. If the combination of array units can be switched by a dip switch or the like, a desired set value can be easily obtained from a plurality of load amounts. If the speed of the manual operation can be arbitrarily adjusted in this manner, the amount of washing water and the operation sequence can be changed according to the purpose and application. For example, fine adjustment at the time of shipment from the production line, change according to the operating conditions at the installation site, or change according to the specifications of the product to be mounted, for various purposes and applications using a common unit It can be easily handled. Further, if the load amount can be changed in conjunction with the manual operation unit 20 or the operation means 19, a plurality of cleaning modes can be easily set, which is preferable. In addition, a light-emitting body such as a light bulb or a light-emitting diode, a rechargeable storage battery, or the like can be connected to the electric load 108. It is preferable to connect the light emitter because it is possible to inform the user of the operation without supplying electric energy from outside. Further, when a storage battery is connected, the generated power can be used other than during operation, which is preferable.

If a stepping motor or a synchronous motor is used as the speed setting means 11, the positioning torque is easy because the holding torque is large, and the amount of operation is determined according to the number of pulses applied from the driver 103, so that simple and accurate time control is performed. Becomes possible. Even in the case of manual operation, the number of pulses corresponding to the number of rotations can be obtained, so that it is possible to easily confirm whether the motor is operating at a predetermined number of rotations. If a brush motor or a DC brushless motor is used, the starting torque for starting to move from a stationary state can be set small, so that the operating force in manual operation can be set small, and the electric load 108 is large because the power generation is large and the internal resistance is small. This is preferable because the torque adjustment range obtained by the change can be widened and the braking force can be set widely. These may be selected optimally according to the application and purpose within the design range of the valve device.

The starting unit 105 has a wired connection, but may be a wireless connection using a remote controller or the like. In the case of a wireless connection, there is provided transmitting means for detecting activation and transmitting a start signal, and output means for detecting and outputting a signal, and the output means detects a signal transmitted wirelessly from the transmitting means. The output means is connected to the controller 106 by wire and transmits an output signal to the controller 106. With this configuration, the activation unit 105 can be moved to an arbitrary location,
We do not choose setting place. Also, since no driving force is required,
Even elderly people and children can easily operate.

It is desirable that the activation unit 105 and the operation unit 19 are installed at different positions. For example, operating means 1
9 can be reliably driven if it is fixedly installed on the valve device main body or in the vicinity of the valve device, and the transmission loss of the driving force is small. The activation unit 105 may be provided movably or may be installed separately from the valve device, and remote control is also facilitated. Further, the activation unit 105 may be configured to operate in conjunction with the driving of the operation unit 19. Starting unit 105
May be a combination of a plurality of the above configurations. Activation unit 1
05 may be provided in plurality, or a plurality of cleaning modes may be selectable. Controller 10
By arranging the manual operation unit 20 and the manual operation unit 20 at a predetermined distance, there is no possibility of electric leakage.

FIGS. 4, 5, and 6 show schematic views of a valve body according to the first embodiment of the present invention. FIG. 4 shows the manual operation unit 2.
FIG. 5 is a cross-sectional view, and FIG. 6 is an operation principle diagram of the valve body 151 driven by 0. The valve body 151 includes a main valve portion 152 and a switching valve portion 156,
It is fixed by a snap fit at the fastening portion 155. The main valve section 152 includes a main valve 154 and a water supply port 153. The switching valve unit 156 includes a first switching valve 159,
It comprises a second switching valve 165 and a vacuum breaker 163. A constant flow valve 172 for controlling the flow rate to be substantially constant irrespective of the water supply pressure is inserted into the fastening portion 155. The main valve 154 and the first all-replacement valve 159 are provided with a pilot port 171 and a pilot port 160, respectively. Note that the constant flow valve 172 may be inserted into the flow path inside the water supply port 153 as shown in FIG. The constant flow valve 172 is formed of a substantially trapezoidal coil spring, and the gap area of the coil spring changes due to a pressure difference between the front and rear. When the pressure difference is large, the displacement amount of the coil spring increases and the gap area decreases. When the pressure difference is small, the displacement amount of the coil spring decreases and the gap area increases. Since the air passes through the gap at a flow rate proportional to the square root of the pressure difference, the spring constant and structure of the coil spring are determined so that the area of the gap is inversely proportional to the square root of the pressure difference.

The water supplied from the water supply port 153 to the main valve section 152 is controlled to flow and stop by the main valve 154, flows through the constant flow valve, and then flows into the switching valve section 156. Normally, the pilot port 160 is closed and the first all-replacement valve 159 is in a closed state, so that the inflowing water passes through the second inflow path 157, pushes up the second switching valve 165, and flows to the second outflow path 162. . Next, pilot port 160
Is opened, a small hole portion 173 in which a part of the water passes through the first inflow passage 158 and is opened in the first all-replacement valve 159.
Through the pilot port 160 to the outside. As the pressure drops when passing through the small hole 173,
The back pressure of the first all-replacement valve 159 decreases and is driven to the open state, and the water flows to the first outflow passage 161. When there is water flow to the first outflow channel 161, the pressure in the first outflow channel 161 increases due to a load (not shown) communicating with the downstream side of the first outflow channel 161, and this pressure passes through the communication port 164, and the second switching valve 165. Increase back pressure. When the predetermined back pressure is reached, the second switching valve 165 is driven to the closed state, and the flow to the second outflow passage 162 stops. By controlling the opening and closing of the pilot port 160 in this manner, the switching valve portion 156 selectively switches between the first outflow path 161 and the second outflow path 162 to perform water flow to the outside. The same applies to the main valve portion 152,
The open / close state of the pilot port 171 is controlled to
6, the back pressure changes, and the opening and closing of the main valve 154 can be controlled. Vacuum breaker 163
Is opened to the atmosphere when the valve body 151 is in a non-operating state and water is stopped, or when the first water passage 167 and / or the second water passage 168 is in a negative pressure state. A predetermined air gap is provided in a water passage (not shown) communicating with the second outflow passage 162 and these flow passages. The valve body 151 is installed so as to be directed substantially vertically downward in the direction of gravity as shown in FIG.

The valve body 151 and the manual operation section 20 are connected as follows. Water inlet 8 and pilot port 171,
The water inlet 5 and the pilot port 160 communicate with each other. Both the water outlet 2 and the water outlet 9 are open to the atmosphere.
As a result, the main valve 154 is driven to open and close by opening and closing the valve element 7, and the first replacement valve 159 is driven to open and close by opening and closing the valve element 4. That is, by applying a predetermined operation to the operation means 19 of the manual operation unit 20, the first cam 17 drives the valve element 7 to open, and in conjunction with this, the main valve 154 is opened,
The water flows out from the second outflow channel 162. When the operating means 19 is released, for example, when the user releases his / her hand from the operating means 19, the first gear 18 reverses to engage the clutch 14, and the braking force by the speed setting means 11 and the urging means 16 The valve body 7 is maintained in the open state by the second cam 13 which is driven to rotate at a predetermined speed by the balance of the load. Third cam 10
Is the valve element 4 to open drive after a predetermined time T _1, the second switching valve becomes the first switching valve 159 in conjunction with which an open state 16
5 is closed, the outflow from the second outflow channel 162 stops, and water flows out from the first outflow channel 161 instead. Then the third cam 10 after a predetermined time T ₂ are the valve 4 was closed drive, outlet passage into the second outflow passage 162 similarly switched. Further the second cam 13 after a predetermined time T ₃ the valve 7 is closed driven, the main valve 154 to stop all water passing by closed. Finally, the manual operation unit 20 performs idle running for a predetermined time and stops operation. Valve body 1 for electric operation
The control procedure of 51 is the same as in the case of manual operation.

FIG. 7 is a timing chart showing the operation of the valve body and the flow of water. FIG. 7A shows a timing chart of water passage, in which the vertical axis represents the water flow amount and the horizontal axis represents time. Further, the water flow rate indicates the water flow rate of the first outflow path 161 and the water flow rate of the second outflow path 162, and the total water flow rate which is the sum of the two. FIG. 7B shows a timing chart of the opening degree of the valve bodies 4 and 7, wherein the vertical axis represents the opening degree and the horizontal axis represents time. The opening is
The opening degrees of the valve element 4 and the valve element 7 are shown. t = T

These _{T x, T y, T g} represents the operation delay time of the valve body 151 which is controlled by the opening and closing operation of the valve body 4, 7 none. Since these operation delay times are inherent times determined by the structure of the valve, etc., they can be grasped in advance, and the drive time of the valve body should be determined in consideration of these operation delay times with respect to the desired water flow time. I just need. Note _{here, T b = T 2 -T x} , T c = T 3 +

_{In z} ), all operations are stopped and the operation returns to the initial position. By providing a predetermined idle running distance even after the end of the valve body control as described above, it is possible to reliably stop water even when mechanical accuracy is deteriorated due to aging or the like.

As described above, when the valve body control methods in the manual operation and the electric operation are completely the same, the operation delay time is completely the same, so that the valve body control time can be made the same. The speed setting means 11 in the operation and the timer in the electric operation have substantially the same time setting.

FIG. 8 shows a valve configuration according to the second embodiment of the present invention. The valve body 151 includes a manual operation unit 2
0 and the electric operation unit 181 are connected. Electric operation unit 1
A valve element 182 and a valve element 187 are provided at 81 and open and close pilot ports 160 and 171 respectively. As the valve elements 182 and 187 in the electric operation, solenoid valves using solenoids are used, and the valve elements are opened and closed by turning on and off electric power from power supply means (not shown). Have different structures. That is, different pilot control valves are used for manual operation and electric operation, and a common main valve is controlled. By doing this,
Since the actuators and mechanisms optimal for manual operation and electric operation are respectively provided, the operability is excellent and the structure can be simplified.

The valve bodies 182 and 187 are provided with water inlets 183 and 186, respectively, and are provided with water outlets 184 and 185, respectively. Each of the water outlets 184 and 185 is open to the atmosphere. The valve body 151, the manual operation unit 20, and the electric operation unit 181 are connected by a hose, and are arranged according to the design. In particular, since the electric operation unit 181 is fixed to the valve body 151 and the manual operation unit 20 is configured separately from the valve body 151, the degree of freedom in layout is improved. A power supply unit (not shown) is connected to the electric operation unit 181, and the power supply unit and the valve main body 151 are connected to each other by a predetermined distance so that there is no risk of electric leakage. The manual operation unit 20 and the electric operation unit 181 are connected in parallel to the valve body 151, respectively, and the valve body 151 is controlled by operating one of them. As a matter of course, the power supply means is provided with timer means for controlling the electric operation unit for a predetermined time.

As described above, when using different valve body control methods, it is desirable to set the time in accordance with each operation delay time. For example, when the operation delay time is different between the manual operation and the electric operation, the timer setting in the electric operation and the speed setting means 11 in the manual operation are performed so that the water passage time is made substantially the same according to each operation delay time. The time, cycle, speed, and the like of the valve body control respectively determined in the above may be set differently.

FIG. 19 shows an example in which a time setting value for electric operation and a time setting value for manual operation, which can be selected by a user or the like, are shown. Four types of setting values are shown for electric operation, and two types of setting values are shown for manual operation. Two types, electric and manual, that is, E1 and M1, and E3 and M2 have the same time set value. E3 and M2 assume the most frequently used normal mode, and this mode is normally selected. On the other hand, E1 and M1 are set to a short time, and a water saving mode in which the water flow time is shorter than the normal mode is assumed. The user can arbitrarily select the normal mode and the water saving mode. E2 in electric
Is set to have a shorter water flow time than the previous water saving mode, and represents a super water saving mode. E4
The total water flow time is the same as E1, but the time distribution is set differently, and the water flow time is the same, but usually according to the purpose and use of the installation site or according to the user's preference. The mode is a fine adjustment mode for finely adjusting the mode. All of these may be changed by the same setting means, or different setting means may be provided to prevent careless changes.

FIG. 10 is a schematic block diagram of the valve drive in this embodiment. Here, the operating means 1 corresponding to the manual operation unit 20 and the electric operation unit 181 respectively.
9 or the activation unit 105, depending on which is selected and operated, the main valve unit 15 which is a common valve body manually or electrically.
2 is shown. Both the manually driven valve body 7 and the electrically driven valve body 201 operate the pilot to control the main valve 152 capable of opening and closing at a larger flow rate. Fifteen
The water driven to open and close by 2 is output. By operating the pilot, the valve bodies 7, 201 themselves can be configured to be very small, so that the response delay can be minimized, and the time setting can be made accurately and easily. The valve body 201 may be of any type. In this case, the structure is simple and reliable power saving operation is possible. Even when the power supply is cut off due to a power failure during operation, etc. Uses a solenoid valve that uses a solenoid that automatically returns and stops water. It should be noted that the waste water section 202 through which a very small flow rate of water for pilot control is performed may be merged with the water discharge section 203 or may be taken out to the outside as open to the atmosphere.
