Faucet body a is the counter etc. is installed on the installation surface e, and the water treatment equipment b, primary and secondary side water supply channels d1 and d2 It is arranged below the installation surface e. On the upstream side of the faucet body a in the primary water supply channel d1, A stopcock d1' is provided.

[0016] The faucet main body a has a discharge port a1 at the tip of a spout portion 1 extending on the peripheral wall, and a main body. Inside the body a, the primary and secondary side water supply channels d1 and d2 are drawn in, and a handle is also installed. An on-off valve (not shown) is activated by the operation in step 2 to open and close either one of the water supply channels d1, d2. (without).

[0017] The water treatment device b is replaceably loaded with a cartridge 3 containing a filter such as a hollow fiber. With a well-known water purifier, the tap water (raw water) flowing in from the inlet b1 is filtered into the cartridge 3. The purified water is filtered and sent out from outlet b2.

[0018] A quantitative water stop part f installed on the installation surface e is installed in the middle of the secondary side water supply channel d2. establish.

[0019] The quantitative water stop part f is constructed as shown in FIGS. An outflow port 22 is provided, and a flow connecting the inflow port 21 and the outflow port 22 is provided inside the outflow port 22. A road 23 is defined. The inlet 21 is the outlet b2 of the water treatment device b, and the outlet 22 is the outlet a1 are connected to each other through the above-mentioned secondary side water supply channel d2. The upper surface of the main body 20 will be described later. A setting handle 51 is provided and an exchange point 20 is provided adjacent to the setting handle 51. a and a starting point 20b are provided as shown in FIG.

[0020] 24 is a valve seat formed at the inlet of the flow path 23, and a piston valve body is mounted on the valve seat 24. 25 corresponds to form a water stop valve f1. The water stop valve f1 opens and closes the flow path 23. The piston valve body 25 slides on the inner peripheral surface of the lid 26 screwed onto the main body 20. A pressure chamber 27 is formed behind the piston valve body 25 by the valve body 25 and the lid 26. ing.

[0021] The pressure chamber 27 communicates with the inlet 21 through a small hole 28 formed in the piston valve body 25. and is connected to the flow path 23 by a relief valve f2. relief valve f2 The relief valve body 29 is always biased in the valve closing direction by a spring 30, and The valve shaft 31 is slidably inserted into the cylindrical guide 25a of the piston valve body 25 and the tip thereof The end protrudes into the flow path 23.

[0022] 32 is a drainage groove formed along the axial direction on the outer circumference of the valve shaft 31, and The water in the chamber 27 is made to flow out into the flow path 23.

[0023] 33 is a retaining ring attached to the outer periphery of the lower end of the valve shaft 31, and is attached to the cylindrical guide. This corresponds to the lower end of the door 25a.

[0024] This retaining ring 33 is attached to the cylindrical guide 2 as the relief valve body 29 is displaced upward. 5a and push up the piston valve body 25 via this guide 25a. do.

[0025] f3 is a water volume function unit, which includes a water volume setting cam 40, a reduction gear train 41, and a blade wheel 4. 2 are connected to each other, and these are made of synthetic resin such as polyacetal resin. The cartridge-type It is attached to the main body 20.

[0026] The water amount setting cam 40 has a notch 40b in a part of the curved cam surface 40a. shaped, and is fixed to the camshaft 44 and placed in the flow path 23 directly below the water stop valve f1. It is. As the cam 40 rotates, the cam surface 40a is relieved. The valve body 29 contacts the lower end of the valve shaft 31 and pushes up the shaft 31 against the elastic force of the spring 30. to open the relief valve f2, and when it rotates approximately one turn, the elastic force of the spring 30 opens the relief valve f2. The valve shaft 31 falls into the notch 40b from the end of the cam surface 40a and opens the relief valve f2. Make the valve close.

[0027] On the other hand, the camshaft 44 has a gear 45 attached to one end and a reduction gear train at the other end. 41 final gears 41n are attached.

[0028] The gear 45 is a handle shaft 4 of a setting handle 51 that constitutes an operating section f4 to be described later. 6, the setting handle 51 engages with the gear 47 pivoted on the 1, the rotation is transmitted to the camshaft 44 via the handle shaft 46, and the water The amount setting cam 40 is made to rotate approximately one revolution in the opposite direction to the setting handle 51.

[0029] The final gear 41n of the reduction gear train 41 is connected to the camshaft 4 via frictional attachment means. 4, and the rotation from the gear input 41 is transmitted to the camshaft 44, but conversely the rotation from the gear input 41 is transmitted to the camshaft 44. The rotation of the camshaft 44 due to the rotational operation of the dollar shaft 46 is not transmitted to the gear train 41. The sea urchin is turning.

[0030] Further, the first gear 41a of the reduction gear train 41 is connected to the rotating shaft 48 of the impeller 42. It meshes with the attached gear 49.

[0031] The impeller 42 is fixed to the rotating shaft 48 and blocks the flow path 23 on the downstream side of the water amount setting cam 40. The rotating shaft 48 and the The gear 49 is made to rotate.

[0032] Therefore, the rotation of this impeller 42 is reduced by the reduction gear train 41, and the rotation of the impeller 42 is reduced by the reduction gear train 41. When the total number of rotations of the impeller 42 reaches the effective amount of water used by the filter, the state shown in Fig. 5 is reached. The camshaft 44 and water volume settings are set at a reduction ratio that allows the cam 40 to rotate to the state shown in Figure 3. The signal is transmitted to the cam 40.

[0033] Then, there is an operation part f4 that operates the water flow function part f3 to set the water flow rate. You will be contacted.

[0034] The operation part f4 communicates with the water metering function part f3 via the ratchet part f5, and the ratchet part Only the turning operation of the setting handle 51 in the setting direction g1 by the g part f5 is the water metering function. If the setting handle 51 is operated in the opposite direction, In this case, the operating section f4 moves idly.

[0035] The setting handle 51 is linked to the handle shaft 46 via the transmission member 50, and is shown in FIG. When the water stop valve f1 is closed as shown in 2.3, the setting handle 51 is provided on the outer surface. The index 51a is set to point to the exchange point 20a (see FIG. 4).

[0036] The transmission member 50 transmits the rotation of the setting handle 51 to the water metering function part f3. Ru.

[0037] The transmission member 50 is spline-fitted to the handle shaft 46 and rotates integrally with the shaft 46. The ratchet teeth 52 are connected to the front surface on the setting handle 51 side. It is formed in a continuous ring shape.

[0038] As shown in FIG. The shape has an inclined surface 52b that becomes lower toward the setting direction g1 of the handle 51. , a pin 53 provided on the setting handle 51 is adapted to engage.

[0039] The pin 53 is housed in a housing hole 54 formed in the setting handle 51 so as to be freely retractable. It is urged toward the transmission member 50 by a spring 55. Therefore, these transmissions Ratchet tooth 52 of member 50, pin 53 of setting handle 51 and spring 55 The ratchet portion f5 is formed by the above steps.

[0040] When the setting handle 51 is rotated in the setting direction g1, the pin 53 is rotated. The rotation of the setting handle 51 is transmitted by being locked to the upright surface 52a of the ratchet teeth 52. The rotation of the member 50 causes the handle shaft 46 to rotate.

[0041] Also, when the setting handle 51 is rotated in the opposite direction to the above, the pin 53 will be ratcheted. The setting handle 51 passes over the inclined surface 52b of the tooth 52, and the rotation is transmitted. It is not transmitted to the member 50. Therefore, the handle shaft 46 does not rotate.

[0042] Therefore, the purified water discharged from the discharge port a1 is filtered by the quantitative water stop part f. To close the flow path 23 when the body's effective amount of water is reached, first turn the setting handle 51 As shown in FIG. b (see Figure 6). When the setting hand 51 rotates approximately once, the rotation changes. It is transmitted to the handle shaft 46 via the ratchet part f5, and the shaft 46 rotates.

[0043] Then, the rotation of the handle shaft 46 is transmitted to the cam shaft 44 via gears 47 and 45. , the cam 40 is moved approximately once in the opposite direction to the setting handle 51 (in the direction of arrow g2 in FIG. 3). Then push up the relief valve body 29 against the spring 30 and open the relief valve f2. Ru.

[0044] With the opening of the relief valve f2, the water in the pressure chamber 27 flows to the flow path 23. 7 becomes equal to atmospheric pressure, thereby causing water pressure and latching of the relief valve body 29. When the ring 33 pushes up the cylindrical guide 25a, the piston valve body 25 moves smoothly. , and the water stop valve f1 opens (the state shown in FIG. 5).

[0045] Then, with the opening of this water stop valve f1, the flow path 23 is opened, and the purified water from the water treatment device b is Water flows into the channel 23.

[0046] From this state, if you open the on-off valve by operating the handle 2, purified water will be discharged from the outlet a1. It will be done. At this time, the impeller 42 rotates due to the purified water flowing through the flow path 23, and its rotation is reduced. The speed is reduced by the high speed gear train 41 and transmitted to the camshaft 44, and the cam 40 , the setting handle 51 is rotated in the opposite direction to g1, and the water stop valve f1 is opened. The valve state is maintained (FIGS. 5 and 6).

[0047] Then, the total flow rate of purified water flowing through the flow path 23, that is, the purified water discharged from the discharge port a1. However, when the above-mentioned effective amount of water used by the filter body is reached, the cam 40 returns to the state shown in FIG. By this, the valve 31 of the relief valve body 29 is removed from the notch part from the cam surface 40a of the cam 40. 40b, the relief valve f2 closes, and the air enters the pressure chamber 27 through the small hole 28. Purified water flows in from the inlet 21, and as the water flows in, the piston valve body 25 gradually lowers. As the water drops, the water stop valve f1 closes slowly and the water discharge is automatically stopped (see Figure 3). (see).

[0048] In this state (the state shown in Figure 3), operate the handle 2 of the faucet body a to open the on-off valve. However, water is not discharged from the discharge port a1. Also, at this time, the setting handle 51 is By returning to the initial state (the state shown in FIG. 4) and pointing the index 51a to the exchange point 20a, The filter body has reached its expiration date, that is, it is time to replace the cartridge 3. Make the user aware.

[0049] Furthermore, during use, the indicator 51a of the setting handle 51 is as shown in FIG. It is located between FIG. 4 and serves as a rough guide to when the cartridge 3 should be replaced.

[0050] In addition, from the state shown in FIG. 4, the user may accidentally move the setting handle 51 in the opposite direction to the setting direction g1. When turned in the opposite direction, only the setting handle 51 is rotated idly by the ratchet part f5. , the handle shaft 46 does not rotate.

[0051] Therefore, the camshaft 44 and the cam 40 do not rotate in opposite directions, and the cam 40. No excessive force is applied to the reduction gear train 41, valve shaft 31, etc. Therefore, damage to the water metering function part f3 can be prevented.

[0052] In addition, the above-mentioned quantitative water stop part f is not necessarily provided in the middle of the secondary side water supply channel d2. Instead, it may be provided in the middle of the primary water supply channel d1 as shown in FIG. Further, in the water faucet with a water treatment device according to claim 1, the water stop valve f1 and the relief valve f It is possible to achieve the intended purpose without providing 2.

[0053] Next, see FIGS. 12 and 13 for an embodiment of the faucet with a water treatment device according to claim 3 or 4. and explain. First, an embodiment according to claim 3 will be explained. This embodiment is a water treatment plant shown in FIG. In place of the quantitative water stop part f in a water faucet with a control device, a flow meter is installed in the middle of the secondary side water supply channel d2. In addition to providing a control unit i, a control unit i and a warning unit j are provided.

[0054] The flowmeter h is connected to an inlet 61 connected by a flow path 60, as shown in FIG. 13, for example. A casing 63 having an outlet 62 and an outlet 62 is provided in the middle of the flow path 60. The impeller 64 rotates by being driven by purified water flowing through the impeller 64, and the rotation shaft of the impeller 64. A magnet 66 integrally provided with the magnet 65 and a sensing element that detects the magnetic field of the magnet 66. The detection element 67 detects the number of pulses or the pulse interval due to the rotation of the magnet 66. It detects it, outputs an electrical signal, and sends the same signal to the control section i.

[0055] The control unit i is electrically connected to the flowmeter h, the warning means j, and the power supply k, and is configured to control the flow rate. Upon receiving the electric signal from the meter h, the warning means j is activated based on the signal, and the user This allows the user to recognize that it is time to replace the cartridge 3.

[0056] That is, the control unit i controls the number of pulses or the pulse interval detected by the sensing element 67 of the flowmeter h. Calculate the instantaneous flow rate from , count the flow rate, and adjust the total flow rate to the preset setting When the constant flow rate, that is, the amount of water effectively used by the filter body is reached, a command is issued to activate the warning means j. It is something that can be done.

[0057] The warning means j is a lamp that lights up or makes a sound when receiving a command from the control unit i. A buzzer or the like is placed above the installation surface e, and is controlled as described above to notify the user of the cart. Informs when to replace ridge 3. In addition, the flow meter h mentioned above may be provided in the middle of the primary side water supply channel d1.

[0058] The faucet with a water treatment device according to claim 4 has a control part i of the faucet shown in FIG. It is configured as described below. That is, the number of pulses detected by the sensing element 67 of the flow meter h or calculates the instantaneous flow rate of the secondary side water supply channel d2 from the pulse interval, and the instantaneous flow rate is When the set instantaneous water flow rate is reached, a command is issued to activate the warning means j. Well, it was configured.

[0059] The set instantaneous water flow rate is the second value of water treatment device b when the filter body reaches its expiration date. The instantaneous water flow rate on the next side, more specifically, the filtration capacity due to the accumulation of bacteria and impurities in the filter body. As the power decreases (the filter becomes clogged), the moment on the secondary side of water treatment device b The flow rate also gradually decreases, and the instantaneous flow rate is set when the decrease reaches the lowest limit. Ru.

[0060] Next, an example of a water faucet with a water treatment device according to claim 5 or 6 is shown in FIG. 14. I will refer to and explain. In this embodiment, the faucet warning means j shown in FIG. In addition, an electric valve l is provided in the middle of the secondary water supply channel d2.

[0061] The electric valve l is of a well-known structure (for example, an electric valve operated by a command from the control unit i). The amount of water flowing through the primary or secondary water supply channels d1 and d2 is filtered using magnetic on-off valves, etc., as described above. The effective amount of water used in the body is reached, or the instantaneous water flow rate of the secondary side water supply channel d2 is the lowest limit. When it reaches, it operates and closes the secondary side water supply channel d2. In addition, the electric valve l is the primary side water supply channel. It may be provided in the middle of d1. Incidentally, in the faucet described in claim 5, it is not necessary to necessarily provide a warning means j. Needless to say, there is no such thing.

[0062] In addition, in the embodiments shown in Figures 12 and 14, only the faucet body a is placed on the installation surface e. Since all you have to do is set the (peripheral surface) can be used effectively, and the area around the faucet body is neat.

[0063]

[Effect of the idea]

Since the faucet with a water treatment device of the present invention is constructed as explained above, the filter body can be used effectively. It is possible to make the user aware that the expiration date has been reached. Therefore, the life of the filter Without realizing that it is broken, that is, the filtration ability to purify water is lost. There is no need to worry about continuing to use the filter.
