Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a faucet device having an operation drive unit such as a timer that automatically stops water supply after a predetermined set time has elapsed.

2. Description of the Related Art Various proposals have been made regarding faucets equipped with timers that are used in bathrooms and the like and which stop water supply after a predetermined period of time.

For example, the device disclosed in Japanese Utility Model Application Publication No. 41-752 has a main valve that closes the main valve hole, and this main valve is further provided with a sub-valve hole, which is closed by the sub-valve. The valve is closed, and this sub-valve is operated by a timer.

Problems that the invention aims to solve However, since this device has a complicated water path, there is a risk that the water flow resistance will be large and the water supply capacity will be reduced.

In addition, Japanese Utility Model Application Publication No. 48-8,757 discloses a system in which the valve operating rod of a valve for opening and closing a flow path is pressurized by a cam operated by a timer.

However, this device has a complicated mechanism and is large in size.

Furthermore, although there are devices that electrically control both the set time of a timer and the amount of water supplied from a faucet, the reality is that they are expensive because they use motors, solenoid valves, etc.

The present invention was made to solve the drawbacks and problems associated with the conventional technology described above, and it is possible to freely mechanically set the water supply time or the amount of water supplied from the faucet between normally closed and normally open. To provide an inexpensive and small-sized faucet device that can not only be easily attached to a water pipe or the like but also direct the water supply direction of the faucet in a predetermined direction.

Means for Solving the Problems In order to achieve the above object, the present invention provides a flow control section for adjusting the flow rate on the flow path inlet side of the main body connected to the end of the water pipe. In a faucet device, a valve body for opening and closing the flow path is installed on the outlet side of the flow path, and the valve body is configured to be opened and closed by a valve operating mechanism connected to an operation drive unit, the valve body comprising: It is a free ball valve of a size that allows a flow path to be closed by water pressure, and the valve actuation mechanism includes a valve actuation piece that displaces the ball valve from a flow path closing position, and a drive member that rotates this valve actuation piece. a fixed plate through which the drive member is inserted and attached to the main body; a rotary plate provided opposite to the fixed plate and rotated by a control rod protruding from the operation drive unit; a protrusion that is fitted into a guide groove formed in the rotary disk and protrudes from the driving member so as to transmit the rotation of the rotary disk to the driving member; each having an arcuate flange that rides on each other according to a predetermined rotation angle of the rod to move the rotary plate and the stationary plate closer to each other and thereby engage and disengage the protrusion and the guide groove;
Further, the present invention is characterized in that a clutch portion is configured such that the rotary disk is brought into pressure contact with the fixed disk by a spring.

As described above, in the present invention, the ball valve, which is closed due to water pressure, can be displaced by the valve operating piece to open the flow path. The time etc. can be adjusted freely, and since the flow rate can be adjusted separately from this valve operating mechanism, the amount of water supplied can also be adjusted freely. Additionally, the faucet can be attached simply by cutting a thread at the end of the water pipe, making it easy to install.

6b and 37b are formed.

A center hole 38 is formed in the center of this fixed plate 31, and the first, second and third B.
The shaft portion 40 of the drive member 39 shown in the figure is inserted therethrough.

This drive member 39 has two large and small dovetail-shaped protrusions 41a and 41b that are fitted into large and small guide grooves 35a and 35b formed in the rotary disk 30, and a threaded portion 42 on the lower surface of the shaft portion 40. is formed, and a valve actuation piece 43 is attached.

As shown in FIGS. 2 and 3B, this valve actuating piece 43 consists of a disc part 43a that is attached to the stationary plate 31 in close contact, and a tongue part 43b that hangs down from the disc part 43a. 43b displaces the ball valve 13 and opens the synthetic resin valve seat 44 fitted into the main body 11.

In addition, in FIGS. 1 and 2, reference numeral 0 indicates an 0 ring, 45 a seal ring, and 46 a coil spring that is urged downwardly by the rotary disk 30.

Further, as shown in FIG. 1, the flow rate control section 15 has one end screwed to communicate with the main body 11 and an inlet 47 at the other end, and a water passage hole 48 on the outer peripheral surface of the other end. A connecting pipe 49 is formed, a valve cylinder 50 is fitted so as to cover the water inlet 48 of the connecting pipe 49, and a valve cylinder 50 is provided in the valve cylinder 50 so as to close the inlet 47 by a coil spring 51. It has a resilient control valve 52, and the connecting pipe 49 and the valve cylinder 5
By changing the relative position with respect to the inlet 47
and/or the opening degree of the water passage port 48 is adjusted. In other words, the control valve 52
The valve stem 53 is supported by a spring receiver 54, which is the open part 7, and its opening degree is determined by rotating the flow rate control sleeve 54 screwed into both the connecting pipe 49 and the valve cylinder 50. The opening degree of the inlet 47 or the water passage port 48 is controlled, and the inlet 4
The amount of water flowing into the connecting pipe 49 from the water inlet 7 or the water inlet 48 is controlled, and the amount of water flowing into the main body 11 is adjusted.

The water inlet 48 has a through hole 48a and an inclined hole 48b, both of which allow for smooth changes in flow rate, and reference numeral 55 in the figure is a water pipe.

Next, the operation will be explained. First, in order to attach the faucet device 10 to a water supply, a thread is cut at the end of the water pipe 55, and the valve cylinder 50 is screwed into the thread. In this case, if a faucet or the like is attached to the valve barrel 50 in advance, the valve barrel 50 can be attached by simply screwing into the water pipe 55.

In addition, in order to adjust the amount of water discharged by this faucet device 10, loosen the flow rate control sleeve 54 and connect the connecting pipe 49.
The connecting pipe 49 and the valve barrel 50 may be connected by the flow rate control sleeve 54 while keeping the faucet device 10 in a state where the faucet device 10 can discharge water in a predetermined direction by leaving the side free from the valve barrel 50.

After installation in this way, in order to spray water for a predetermined time using the timer T, turn the knob 17 from the 0 position until it reaches a predetermined rotation angle within 90 degrees. When the knob 17 is at the 0 position, the inside of the faucet device 10 is in the state shown in FIG. 4A. That is, the ball valve 13 is brought into contact with the valve seat portion 44 by water pressure to close the valve seat portion 44, and the valve operating piece 43 is located on the side of the ball valve 13, and the dovetail of the drive member 39 is closed. protrusion 41
a, 41b are fitted into the large guide groove 35b and the small guide groove 35a, and the vertical surface 32b of the first flange 32 on the rotary plate 30 side and the vertical surface 36b of the first flange 36 on the fixed plate 31 side are in contact with each other. It is becoming.

Next, when the knob 17 is rotated clockwise until it reaches a predetermined rotation angle of 90 degrees or less, the state shown in FIG. 5B is obtained. The rotation of this knob 17 is caused by the projection 1 of the first system flow.
The engagement of 9 and 21 causes the mainspring spring 25 in the timer T to be wound by a predetermined amount.

Further, in the second system flow, the rotation of the control rod 22 causes the rotary disk 30 to rotate by a predetermined angle within 90 degrees, and the first flanges 32 and 36 of the rotary disk 30 and the fixed plate 31
The vertical surfaces 32b, 36b, 33b, and 37b are separated from the mutually abutting state.

When the rotation angle becomes 90°, the inclined surfaces 32a and 33a of the first flange 32 and second flange 33 on the rotary plate 30 side are the same as the inclined surfaces 36a and 33a of the first flange 36 and second flange 37 on the fixed plate 31 side, respectively. 37
It comes into contact with a.

In other words, between 0 and 90 degrees, the flange 32 on the rotary plate 30 side rotates on the rotary plate 31, and on the contrary, the flanges 36 and 37 on the fixed plate 31 side only rotate on the rotary plate 30, so to speak, the clutch portion 23 They are in a connected state, and the semicircular flanges 34a, 34a rotate the valve operating piece 43 via the drive member 39.

Therefore, the ball valve 13, which was in the closed state only by water pressure at the 0 position, is displaced from the valve seat portion 44 by the operation of the valve actuation piece 43.
Water passes through the valve seat portion 44 and flows out from the water outlet 60.

While this water is being sprayed, the mainspring spring 25 releases its torsional energy and
Rotate the drive shaft 20 counterclockwise. Due to this rotation, the protrusion 21a engages with the second protrusion 19, and the knob 1
7 is returned to its original position, the control rod 22 is also returned to its original position, and the valve operating piece 43 returns to its original position from the position where the ball valve 13 was pushed away. In this case, since water pressure is constantly acting on the ball valve 13, when the valve actuating piece 43 is displaced, the valve seat portion 44 is gradually closed, and finally reaches the 0 position described above.

Next, when the knob 17 is rotated beyond 90 degrees, the first and second flanges 32 and 33 of the rotary disk 30 have their inclination angles 32a and 33a that are different from those of the first and second flanges of the rotary disk 31.
The flanges 36 and 39 ride on the inclined surfaces 36a and 39a, and are guided by the inclined surfaces, so that the flanges 32 and 33 on the rotary plate side are connected to the flanges 3 on the fixed plate side.
6 and 37, and the rotary plate 30 is in a position separated from the fixed plate 31.

In other words, this separation means that the semicircular flanges 34a, 34b on the rotary disk 30 side are disengaged from the drive member 39, and as a result, the clutch portion 23 becomes disengaged. The member 39 remains stationary on the fixed platen 31.

Therefore, the valve operating piece 43 which is in an interlocking relationship with the driving member 39 is in a state of being inserted between the ball valve 13 and the valve seat portion 44, and the ball valve 13
The valve is in a position away from the valve seat 44, that is, a normally open state where the maximum amount of water can be discharged. Note that since the valve operating piece 43 may be located at a position where the valve seat portion 44 is closed, it is necessary to have a shape that does not interfere with the flow of water. Further, although the driving member 39 is resiliently repelled by the coil spring 46, since the driving member 39 of the rotary disk 30 and the semicircular flanges 34a and 34b are slippery, there is no problem in operation. The member 39 is stopped by two O-rings installed in the center hole 38 of the stationary platen 31, and remains stationary at a predetermined position without being displaced.

After starting water discharging in this way, the mainspring spring 25 releases torsional energy, and the ball valve 13 remains in the normally open state where the maximum amount of water can be discharged until the rotation position of 90°. The above-mentioned closing starts from the position , but since this is the same effect as described above, the explanation will be omitted.

Finally, when the knob 17 is rotated beyond 330°, the protrusion 61 (see Fig. 2) provided at the 330° position on the casing 24 of the timer T is replaced by the first protrusion 62 (see Fig. 2) provided on the knob 17 side. (see Figure 2).

Since this protrusion 61 is formed into an inclined surface that is easy to cross over and difficult to return to, the first protrusion 61 of the knob 17
Although the protrusion 62 can go over the protrusion 61, it is difficult to return, and the knob 17 can only return until the first protrusion 62 comes into contact with the protrusion 61.

In this state, the valve operating piece 43 and the ball valve 1
Since the relationship 3 corresponds to the above-described rotation angle of 90° or more, it is in a normally open state, and the torsional energy of the mainspring spring 25 of the timer is released by the protrusion 61 and the first protrusion. It comes into a stopped state due to contact with 62.

In addition, in order to release the lock between the protrusion 61 and the first protrusion 62, the protrusion can be removed by slightly pulling up the entire knob 17.

In addition, in the above-mentioned embodiment, the operation drive section 16 has a timer T, but the present invention is not limited to the above-mentioned one, but also has a structure in which the timer T is not used.
Direct knob 17 and valve actuation mechanism 1 as shown in FIG.
4 may be directly connected. If you do this,
Although you cannot set the water supply time, you can freely and easily adjust the water supply amount.

Effects of the invention As stated above, according to the invention, the valve body is
It is a free ball valve of a size that allows a flow path to be closed by water pressure, and the valve actuation mechanism includes a valve actuation piece that displaces the ball valve from a flow path closing position, and a drive member that rotates this valve actuation piece. a fixed plate through which the drive member is inserted and attached to the main body; a rotary plate provided opposite to the fixed plate and rotated by a control rod protruding from the operation drive unit;
a protrusion that is fitted into a guide groove formed in the rotary disk and protrudes from the driving member so as to transmit the rotation of the rotary disk to the driving member; Each of the control rods has an arcuate flange that rides on each other in accordance with a predetermined rotation angle of the control rod to bring the rotary plate and the stationary plate closer to each other and engage and disengage the protrusion from the guide groove. Since the clutch part is configured such that the plate is pressed against the fixed plate by a spring, the water supply time etc. can be adjusted mechanically, and the water supply amount can also be freely adjusted independently of the water supply time etc. Additionally, the faucet device can be attached simply by cutting a thread at the end of the water pipe, making it easy to install.
