Description

  The present invention relates to a faucet device, and more particularly to a faucet device capable of selectively discharging different types of water discharge types such as water and hot water, raw water (tap water) and purified water.

Conventionally, water and hot water can be selectively discharged, and a hand-held sensor for water discharge, i.e., a human body-detecting water operation unit that detects the contact without touching the hand, A human body detection type hot water operation unit, and when the user operates one of the operation units, the corresponding water discharge type, that is, one of water and hot water is discharged, and when the other is operated, the water and hot water A water faucet device adapted to switch to the other water discharge is known.
Patent Document 1 below discloses this type of faucet device.
In the faucet device disclosed in Patent Document 1, both the water operation unit and the hot water operation unit are configured to automatically increase and change the water discharge flow rate when the operation duration time is long, specifically, depending on the length of the operation time. There is no.

However, in this faucet device, when the hot water operation unit is operated during the water discharge to switch from the water discharge to the hot water discharge, the water discharge flow rate automatically returns to the minimum flow rate at that time, and the water discharge flow rate is reduced. When it is desired to make the water discharge flow rate the same as that at the time of water discharge, it is necessary to continue the operation of the hot water operation unit to increase the water discharge flow rate.
The same applies to the reverse case, and when switching to water discharge during hot water discharge, even if the corner water discharge flow rate is increased to the desired flow rate, the water discharge flow rate returns to the minimum flow rate when switching to water discharge. Therefore, in order to make the water discharge flow rate the same as the water discharge flow rate at the time of hot water discharge, it is necessary to continue the operation of the water operation unit to increase the water discharge flow rate.

  In a faucet device provided with a water operation unit and a hot water operation unit, the hot water operation unit and the water operation unit may be mistakenly operated. In this case, for example, water will be discharged. In fact, when the operation unit is operated with the water operation unit, even if the corner water discharge flow rate is adjusted to the desired flow rate, it is noticed that the hot water and water are different, and the hot water operation unit is operated again. When the water discharge flow rate returns to the minimum flow rate, the operation for increasing the water discharge flow rate must be performed again in the hot water operation unit, and the operation for adjusting the water discharge flow rate becomes troublesome, In addition, it takes time to obtain a desired flow rate, and the problem remains in terms of ease of use.

  In addition, not only when it is operated by mistake, but when switching from water spouting to hot water spouting or vice versa, even if you want to spout at the water discharge flow rate before switching after switching, Since the water discharge flow rate returns to the minimum flow rate at the time of switching, the operation for adjusting the water discharge flow rate must be performed again, and this also involves the same trouble and also to adjust the water discharge flow rate. It takes time to operate.

  Although the above is an example in the case of switching between water spouting and hot water spouting, the same problem occurs when switching between raw water (tap water) water discharging and purified water water discharging based on the operation of the operation unit corresponding to them.

If it does in this way, operation for adjusting the discharged water flow rate of the discharged water type after switching can be performed easily in a short time.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a water faucet device of the present example, which has a water discharge port 16 at the tip of a main body 14 standing up from a mounting base 12 such as a counter, and for water on the right side and the left side of the tip. An operation unit 18-1 and a hot water operation unit 18-2 are provided.

  In the faucet device 10, as shown in the time chart of FIG. 2, by operating the water operation section 18-1 in the water stop state, water discharge is started from the water outlet 16, and in the water stop state, hot water is started. The hot water discharge is started from the water outlet 16 by operating the operation unit 18-2.

In addition, when the water operation unit 18-1 is operated in the water stop state to start water discharge from the water outlet 16, if the operation on the water operation unit 18-1 is continued, the water discharge is performed according to the operation duration time. The water discharge flow rate from the water port 16 increases and changes.
Similarly, when the hot water operation unit 18-2 is operated in the water stop state to start hot water discharge from the water discharge port 16, and the operation on the hot water operation unit 18-2 is continued, the water discharge port is set according to the operation duration time. The hot water discharge flow rate from 16 increases and changes.

Further, when the operations on the water operation unit 18-1 and the hot water operation unit 18-2 are stopped, the water discharge and the hot water discharge continue at the water discharge flow rate at the time of the operation stop.
And if the water operation part 18-1 is operated again in the state in which the water spouting is performed, the water spouting from the water spout 16 stops at that time.
Similarly, when the hot water operation section 18-2 is operated again while hot water is being discharged, hot water discharged from the water outlet 16 is stopped (water stopped) at that time.

Here, the water operation unit 18-1 and the hot water operation unit 18-2 may be contact type operation units (switches or the like), or human body detection type sensors that detect the hand that is put out without contact. Any of the non-contact type operation units consisting of
Further, here, the water operation section 18-1 and the hot water operation section 18-2 are provided at the tip of the main body section 14, but the water operation section 18-1 and the hot water operation section 18-2 are provided at other locations. It can also be provided in

  In the time chart of FIG. 2, the water discharge flow rate and the hot water discharge flow rate increase and change stepwise as the operation duration time for the water operation portion 18-1 or the hot water operation portion 18-2 becomes longer. However, in some cases, the water discharge flow rate may be continuously increased and changed steplessly.

As shown in the time chart of FIG. 3, in the present embodiment, when the hot water operation unit 18-2 is operated during the water spouting, the water is switched from the water spouting water to the water spouting water, and the water operation is performed during the water spouting water. When the section 18-1 is operated, the hot water spouting is switched to the water spouting at that time.
At this time, in the present embodiment, the final water discharge flow rate before switching and the water discharge flow rate immediately after switching are set to the same water discharge flow rate.
Specifically, when the hot water operation unit 18-2 is operated during the water spouting to switch from the water spouting to the hot water spouting, immediately after the switching at the same water discharging flow rate as the final water discharging flow rate that has already been adjusted before switching. Perform hot water discharge.
Similarly, when switching from hot water discharge to water discharge, the water discharge immediately after switching is performed at the same water discharge flow rate as the final water discharge flow rate of hot water discharge before switching.

In the present embodiment, as shown in the time chart of FIG. 4, when the water operation unit 18-1 or the hot water operation unit 18-2 is operated to switch water discharge, the same operation unit is continuously operated as it is. The final water discharge flow rate before switching is used as the start water flow amount, and the water discharge flow rate changes from there.
Specifically, when the hot water operation unit 18-2 is operated to switch to hot water spout while water is being spouted from the water outlet 16, immediately after switching, the hot water spout is discharged at the same water discharge flow rate as that before the switching. However, if the hot water operating section 18-2 is continuously operated as it is, the discharge flow rate of the hot water discharge gradually increases from there.

Further, by operating the water operation unit 18-1 from this state and switching from hot water discharge to water discharge, the water discharge immediately after switching is performed at the same discharge flow rate as the final discharge flow rate of the hot water discharge before switching. If the water operation unit 18-1 is further operated, the water discharge flow rate further changes from there.
For example, when switching to water discharge, if the maximum flow rate has not yet been reached, the water discharge flow rate further increases from that point, and when the peak maximum flow rate is reached, the water discharge flow rate gradually decreases ( Here, it changes step by step (but may be continuous).

  In the example of FIG. 4, the water discharge flow rate reaches the peak maximum flow rate at the time of water discharge, and then decreases and changes. However, when the water discharge flow rate reaches the peak maximum flow rate during hot water discharge. If the hot water operation section 18-2 is continuously operated as it is, the discharged water flow rate decreases and changes from the maximum flow rate.

FIG.5 and FIG.6 has shown the structural example of the supply apparatus of the water and hot water to the main-body part 14 in the faucet apparatus 10 of this embodiment.
In FIG. 5A, reference numeral 20 denotes a water flow path, and a water stop cock 22, a pressure reducing valve 24, and an electromagnetic valve 26 for opening and closing the water flow path 20 are provided on the water flow path 20.
28 is an electric water heater which introduces and heats water from the water flow path 20 and stores it as hot water. A hot water flow path 30 extends from the electric water heater 28. The hot water channel 30 is connected to the common channel 32 together with the water channel 20.
A flow rate adjustment valve 36 is provided on the common flow path 32, and an electromagnetic valve 34 for opening and closing the hot water flow path 30 is provided.

Here, the electromagnetic valves 26 and 34 and the flow rate adjusting valve 36 are connected to a control unit 38, and the operation of each is controlled by the control unit 38.
The control unit 38 is electrically connected to the water operation unit 18-1 and the hot water operation unit 18-2, and an operation signal is input to the control unit 38 from each. The electromagnetic valves 26 and 34 and the flow rate adjusting valve 36 are controlled by the control unit 38 based on the input of these operation signals to the control unit 38.

As the flow rate adjustment valve 36, for example, a valve that changes the opening of the common flow path 32 in multiple steps or continuously in a stepless manner by driving with a stepping motor or the like is used.
In the case shown in (A), hot water having a temperature held in the electric water heater 28 is supplied as it is.

5B is an example in which a flow rate adjusting valve 36 is provided in each of the water flow path 20 and the hot water flow path 30. In this example, the water flowing in the water flow path 20 and the hot water flowing in the hot water flow path 30 are shown. After the flow rate is adjusted by the flow rate adjustment valve 36, each of these is supplied to the main body 14 through the common flow path 32.
In this example, when hot water is supplied to the main body 14, water is supplied through the water flow path 20, and a predetermined amount of water is added to the hot water from the hot water flow path 30 by the flow rate adjusting action of the flow rate adjusting valve 36. The temperature is adjusted, and hot water having an appropriate temperature adjusted (temperature adjusted) can be supplied to the main body 14.
Of course, if the supply of water from the water flow path 20 is stopped when hot water is supplied, hot hot water having the same temperature as that in the electric water heater 28 can be supplied to the main body 14.

On the other hand, in the case of FIG. 6C, an instant hot water pot 40 is provided on the hot water channel 30 to store and keep the hot water supplied through the hot water channel 30 there. In this example, the main body 14 is supplied through the passage 30 and the common flow path 32.
In this example, a flow rate sensor 42 is also provided on the common flow path 32, and a flow rate detection result by the flow rate sensor 42 is input to the control unit 38, and water sent through the common flow path 32 based on this result. Or it is controlled so that the flow rate of hot water becomes an appropriate flow rate.

According to the present embodiment as described above, the water discharge after switching can be performed at the final water discharge flow rate before switching when the water discharge is switched, and the water discharge after switching is discharged at the same water discharge flow rate as the water discharge before switching. When it is desired to do so, there is no need for any operation for adjusting the water discharge flow rate after switching. For this reason, the operation for adjusting the water discharge flow rate is simplified, the time for adjusting the water discharge flow rate can be shortened, and the usability of the faucet device 10 can be improved.
In the present embodiment, the water discharge flow rate after switching is changed according to the operation duration time for the operation unit corresponding to the water discharge type after switching, with the final water discharge flow rate before switching as the start water discharge flow rate. Therefore, the operation for adjusting the discharged water flow rate can be easily performed in a short time after switching.

Although the embodiments of the present invention have been described in detail above, these are merely examples.
For example, the above embodiment is an example of switching between water and hot water, but the present invention can selectively discharge raw water and purified water, and includes a raw water operation unit and a purified water operation unit corresponding to each, It is also possible to apply to a water faucet device in which the water discharge is switched by these operations and the water discharge flow rate is changed according to the operation duration time of each operation unit .
