Description

  The present invention relates to a water discharge device, and more particularly, to a water discharge device having a function of performing steam injection from a water discharge device.

  Conventionally, hot water from a water heater (hot water supply device) is led to a mixed faucet (water faucet) (hereinafter simply referred to as a faucet) attached to a basin, for example, and mixed with water spouting (usually water (cold water)). When water is used for hand washing, the hot water from the water heater does not reach the faucet easily because of the long distance between the water heater and the mixing faucet. The problem that it came out occurred.

  For this reason, the user must wait for a long time until the appropriate temperature water comes out while touching the temperature of the water discharged from the faucet by hand until the appropriate temperature water is discharged. In addition, there is a problem that it is uneconomical because the cold water discharged before the desired appropriate temperature water is discharged becomes discarded water.

However, in this case, it is necessary to always supply electric energy to the electric water heater, and this electric water heater stores a large amount of high-temperature water, so that there is a problem that energy consumption is high.

In addition, there exist some which were disclosed by the following patent document 1, patent document 2, and patent document 3 as a prior art relevant to this invention.
The one disclosed in Patent Document 1 uses residual water inside the shower hose connected to the shower head of the mixing faucet. In the one disclosed in Patent Document 1, mist water is injected into the shower head. The mist spouting part to be provided is provided, and the residual water inside the hose is sprayed from the mist spouting part.
However, the one disclosed in Patent Document 1 performs mist injection for the purpose of correcting the sleeping hair, and this mist is a mist of cold water that is injected as it is, which is basically different from the present invention. Yes.

  The one disclosed in Patent Document 2 is provided with a mist spout for mist injection in a hand-washing device installed at the upper part of a toilet low tank. It is different from the invention.

On the other hand, what is disclosed in Patent Document 3 is used for jetting steam mist from a mist jet head provided at the tip of a flexible hose, for sucking a cold, setting a hair, or for moisturizing the skin. Unlike the patent document 1 and the patent document 2, the one disclosed in this patent document 3 injects steam mist.
However, those disclosed in Patent Document 1, Patent Document 2, and Patent Document 3 are not to switch to hot water discharge from the hot water supply device after mist injection, and are fundamentally different from the present invention in this respect. .

Effects and effects of the invention

  As described above, the water discharge device according to claim 1 includes a steam injection device that branches the branch flow channel from the main flow channel, generates steam using the water in the branch flow channel, and supplies the water discharge device with the steam injection. A switching means for switching the flow path between the channel and the branch flow path, and steam injection from the water discharger until the detected temperature for the water in the main flow path connecting the water heater and the water discharger reaches the set temperature, and When the detected temperature reaches the set temperature, the flow path is switched, and the hot water from the hot water supply device can be discharged from the water discharger as it is or with cold water while steam generation is stopped.

According to the water discharge device of the present invention, when the hot water from the hot water supply device reaches the water discharge device, the steam is sprayed in a mist form at the initial stage of water discharge, and when performing hand washing or washing, the steam mist Can be pre-washed.
The mist at this time is a steam mist and is warm, and the user can comfortably perform preliminary washing or the like with the steam mist.

Thus, after a certain period of time, the hot water from the hot water supply device reaches the water discharger, and thereafter, the main washing such as hand washing can be performed using the high temperature water.
At that time, the pre-wash using the initial steam mist can raise the dirt attached to the hands, etc., so the main wash using the high-temperature water after that can be used for hand-washing with a slight amount of high-temperature water used. I can finish it.
Therefore, according to the first aspect, the amount of high-temperature water used can be reduced, and the economy can be improved.
Moreover, hand washing etc. can be completed in a short time, and the usability of the water discharge device is improved.

  In addition, it is not necessary to wait for a long time until high temperature water reaches the water discharge device as in the past, and it is not necessary to be frustrated during that time or to check the temperature of the water discharge by touching the water discharge many times. It is possible to use the water discharging device comfortably.

  In addition, since the amount of water used for generating steam is small (for example, steam can be generated by supplying several cc of water to the steam generator), the economy is high. Since the operation starts, that is, the generation of steam starts in response to the water discharge instruction from the instructing means, not only the energy used is originally reduced, but also the required operation time is short, so that the input energy is small.

In this water discharge device, steam injection and water discharge including high-temperature water may be performed from separate water discharge ports, or may be performed from one water discharge port depending on circumstances.
It is desirable that the temperature sensor for detecting the temperature of the water in the main channel be positioned so as to detect the temperature of water at a position as far as possible from the water heater to the water discharger.
As a specific installation position, a branch portion of the branch channel in the main channel or a position immediately upstream thereof is preferable.

  In addition, when the branch channel is opened at the start of use of the water discharge device and the downstream part of the main channel is closed, the temperature sensor is provided in the branch channel to indirectly know the temperature of the water in the main channel It is also possible in some cases.

In Claim 1, the said water discharging tool can be provided in a washbasin, and can discharge water toward a washbasin.
Further, the branch channel can be communicated with the drain channel, and a steam generator can be further communicated with the branch channel via the water channel (Claim 2).

  The amount of water required for steam generation is very small. Therefore, in order to prevent the cold water remaining in the main flow path from being discharged from the water discharge device at the initial stage, much of the cold residual water in the main flow path is discharged. It is necessary to.

  According to the second aspect of the invention, a lot of cold residual water taken out from the main channel through the branch channel can be discharged to the outside through the drain channel, and steam is generated using only a part thereof. Can do.

  In this case, a tank is provided in the branch flow path, the water flowing into the branch flow path is once stored in the tank, and then flows into the drain flow path, and the water stored in the tank is taken into the water flow. It is possible to supply the steam generator through a path (claim 3).

  On the other hand, the water discharge device according to claim 4 is provided with a water storage temperature raising tank for storing the inflow water of the main flow path and raising the temperature by heating with the heater in the main flow path, and starts heating the stored water with the heater based on the water discharge instruction. When the temperature of the stored water reaches the set temperature, the water from the water heater is not sent to the water discharger via the storage temperature rising tank, and before the temperature of the stored water reaches the set temperature, that is, in the initial stage of water discharge. The steam generator generates steam and jets the steam mist from the water discharger. According to the water discharge device of claim 4, the cold residual water remaining in the main flow path is discharged as waste water. Can be avoided.

  For example, if the capacity of the water storage temperature raising tank is set to a few liters, the cold residual water remaining in the main flow path can be guided to the water storage temperature raising tank and stored therein, and this is heated by the heater. It can be supplied to the water discharger after being warmed. As a result, it is possible to eliminate the need to discharge the cold residual water remaining in the main flow path to the outside as the discarded water.

  In the water discharge device according to claim 4, since it takes some time (for example, about 30 seconds) to raise the temperature of the stored water to the set temperature in the water storage temperature increasing tank, the water branched into the branch channel during that time Is steamed by a steam generator and sent to a water discharger, and steam mist is jetted from the water discharger in the early stage of water discharge.

Therefore, even in the water discharge device according to the fourth aspect, it is possible to perform preliminary washing of hands and the like using the steam mist sprayed in the early stage of use of the water discharger.
After that, it passes through the high temperature water heated in the water storage temperature rising tank or the water temperature rising tank, where it is heated by mixing with the high temperature water in the water storage temperature increasing tank (from the water temperature increasing tank). The water in the upstream part) can be sent to the water discharger and discharged from there to perform the main wash.

In this aspect, the branch channel can be extended from the water storage temperature raising tank.
Further, the steam generator can be provided directly on the branch channel without going through the intake channel.

  Further, in claim 4, a second temperature sensor for detecting the inflow temperature of the water in the main flow path to the water storage temperature raising tank is provided, and the second temperature sensor is a high-temperature water from the hot water supply device. When arrival is detected, heating by the heater of the water storage temperature raising tank can be stopped.

  In any one of these claims 1 to 4, the switching means can be configured with one switching valve (three-way valve) provided at a branching portion of the branching channel from the main channel. As a means, it comprises an open / close valve provided in the downstream portion of the main flow path according to claim 5 and an open / close valve provided in the branch flow path, and closes one open / close valve and opens the other open / close valve. By switching in reverse, the flow path can be switched.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a washbasin, 12 is a faucet (mixed faucet) as a water discharger provided in the washbasin 10.
Reference numeral 14 denotes a water heater (hot water supply device) installed outdoors, and 16 denotes a main flow path from the water heater 14 to the faucet 12. Hot water from the water heater 14 passes through the main flow path 16 to the faucet 12. Sent to.

Reference numeral 20 denotes a branch flow path branched from the main flow path 16, and 22 denotes a branch portion thereof.
Reference numeral 24 denotes a tank provided in the branch flow path 20, and water taken out through the branch flow path 20 is temporarily stored in the tank 24.
The water stored therein flows out of the branch channel 20 to the outside of the tank 24 due to overflow, and further flows into a drain channel (not shown), and is then discharged outdoors.

26 is an open / close valve provided in the branch flow path 20, and 28 is an open / close valve provided in the main flow path 16, both of which are electrically driven valves, and are electrically connected to the control unit 30. Operation controlled.
These open / close valves 26 and 28 together constitute a switching means for switching the flow path.
In the figure, 22A and 22B respectively represent an upstream portion and a downstream portion with respect to the branch portion 22 of the main flow path 16, and the open / close valve 28 is provided in the downstream portion 22B.

The on-off valves 26 and 28 that constitute the switching means function as follows.
That is, when the opening / closing valve 28 is closed and the opening / closing valve 26 is opened, the water flowing through the main channel 16 from the hot water heater 16 side flows into the branch channel 20 at the branching section 22, and the opening / closing valve 26 is opened. By closing and opening the on-off valve 28, the water that reaches the branch portion 22 in the main flow path 16 is supplied to the faucet 12 through the downstream portion 22B as it is.

A steam generator 32 has an IH heater (electromagnetic induction heater) 36 inside the container 34.
The steam generator 32 is connected to the tank 24 through a water intake passage 38, and a part of the water in the tank 24 is supplied to the steam generator 32 through the water intake passage 38 by pumping up by the pump 40. The

The steam generator 32 converts the water supplied in an amount of about several cc into steam almost instantaneously by heating by the IH heater 36.
The steam generated here is sent to the faucet 12 through the steam passage 42 and is jetted into the wash basin 10 from the water outlet 13 of the faucet 12 as steam mist.
In FIG. 1, reference numeral 44 denotes a steam injection device including the steam generator 32 and the steam flow path 42.

The main flow path 16 is provided with a temperature sensor (thermistor) 46 that detects the temperature of water in the main flow path 16 at a position immediately upstream of the branch portion 22.
The temperature detected by the temperature sensor 46 is input to the control unit 30 as a signal.
Reference numeral 48 denotes a switch (water discharge instruction means) operated by a user of the faucet 12.

Next, the action of the water discharging apparatus of this embodiment will be specifically described with reference to the time chart of FIG.
In this example, when the user of the faucet 12 opens the operation unit 50 and turns on the switch 48, the temperature of the water in the main flow path 16 is detected by the temperature sensor 46, and the detected temperature is less than the set temperature. At a certain time, first, the opening / closing valve 28 is closed and the opening / closing valve 26 is opened, so that the branch flow path 20 is opened, and the water flowing in the main flow path 16 is supplied by the high temperature water supplied from the water heater 14. 20 and once stored in the tank 24.

The pump 40 starts pumping simultaneously with the ON operation of the switch 48, takes out a part of the water in the tank 24, and supplies it to the steam generator 32 with a supply amount of about several cc.
The supplied water is steamed almost instantaneously by the steam generator 32, is circulated through the steam flow path 42 by the pressure, is sent to the faucet 12, and is jetted from the water outlet 13 as steam mist.
As shown in FIG. 2, the steam generator 32 starts to operate with a slight delay from the ON operation of the switch 48.

When the steam mist is sprayed from the faucet 12 in this way, the user can wet the hand by applying it to the hand and perform preliminary washing.
The steam generated by the steam generator 32 is sent to the faucet 12 and further cooled until it is sprayed from the faucet 12, and then the steam mist from the faucet 12 to a temperature of about 40 ° C. is supplied to the basin 10. Injected towards.

  Even during pre-washing with the steam mist as described above, the high-temperature water sent from the hot water supply device 14 flows downstream through the main flow path 16, and thereby the temperature of the main flow path 16 by the temperature sensor 46. When the detected water temperature reaches the set temperature, the open / close valve 26 of the branch flow path 20 is closed, and the open / close valve 28 of the downstream portion 22B of the main flow path 16 is opened. The flow path is switched to the downstream portion 22B side.

Accordingly, the high temperature water that has reached the set temperature is supplied to the faucet 12 through the main flow path 16, where it is mixed with cold water to obtain an appropriate temperature water, and then discharged from the spout 13 to the basin 10.
The user can perform the main washing after the preliminary washing using the appropriate temperature water.
When the user finishes the operation, the user closes the operation unit 50 to stop the discharge of the appropriate temperature water.
Here, the IH heater 36 of the steam generator 32 stops heating at a timing before the flow path switching from the branch flow path 20 to the downstream portion 22B side of the main flow path 16 is performed.
In this example, the steam mist and the appropriate temperature water are both discharged from the same outlet 13 of the faucet 12. However, it is of course possible to discharge each from a different outlet. .

According to the water discharging device of the present embodiment as described above, steam is sprayed from the faucet 12 in the form of a mist at the initial stage of water discharge until the high-temperature water from the water heater 14 reaches the faucet 12, Preliminary washing can be performed by the steam mist when washing or the like.
The mist at this time is a steam mist and is warm, and the user can comfortably perform preliminary washing or the like with the steam mist.

Thus, after a certain period of time, the high temperature water from the water heater 14 reaches the faucet 12, and thereafter, the main wash such as hand washing can be performed using the high temperature water.
At that time, the pre-wash using the initial steam mist can raise the dirt attached to the hands, etc., so the main wash using the high-temperature water after that can be used for hand-washing with a slight amount of high-temperature water used. I can finish it.
Therefore, according to this embodiment, the amount of high-temperature water used can be reduced, and economic efficiency can be improved.
Moreover, hand washing etc. can be completed in a short time, and the usability of the water discharge device is improved.

  In addition, it is not necessary to wait for a long time until the hot water reaches the faucet 12 as in the past, and during that time, it is irritated or the water is touched many times to check the temperature of the discharged water. It is not necessary to be able to use the water discharging device comfortably.

  In addition, since the amount of water used for the generation of steam is small, it is economical, and the steam generator 32 starts to operate in response to a water discharge instruction from the switch 48, that is, starts to generate steam. In addition, since the required operating time is short, little energy is required.

FIG. 3 shows another embodiment of the present invention.
In this example, a water storage temperature rising tank 52 is provided in the main flow path 16, and the branch flow path 20 extends from the water storage temperature rising tank 52.
Here, the steam generator 32 is not directly connected to the branch channel 20 via the water intake channel 38 as in the above-described embodiment, but is provided in the branch channel 20 directly, and water is directly supplied from the branch channel 20. In response, steam is generated.

The steam generated by the steam generator 32 is sent to the faucet 12 through the steam flow path 42 and is jetted therefrom as mist-like steam. This is the same as in the above embodiment.
Note that the branch channel 20 can be branched and extended from other parts of the main channel 16 instead of from the water storage temperature raising tank 52.

The water storage temperature raising tank 52 includes a water storage tank 54 that stores water by flowing water in the main flow path 16, a temperature sensor 56 that detects the temperature of the internal water storage, and an IH heater 58 that heats the water storage and raises the temperature. The water in the main channel 16 is caused to flow into the interior and the temperature is raised.
In this example, the water storage temperature raising tank 52 has a capacity of about several liters.

The main flow path 16 is provided with a second temperature sensor (thermistor) 60 for detecting the temperature of the water flowing into the water storage temperature rising tank 52 at a position immediately upstream of the water inflow portion into the water storage temperature rising tank 52. .
The temperature sensor 60, the IH heater 58 of the water storage temperature increasing tank 52, and the temperature sensor 56 are electrically connected to the control unit 30.
The IH heater 36 of the steam generator 32 is also electrically connected to the control unit 30. This is the same in the first embodiment.
A switch 62 also serves as a water discharge instruction means operated by the user.

Next, the operation of the water discharging device of this embodiment will be described below with reference to the time chart of FIG.
In this example, when the user turns on the switch 62, the temperature sensor 56 first detects the water temperature in the water temperature rising tank 52, and when the temperature is lower than the set temperature, the IH heater 58 is heated. The operation starts and the temperature of the internal water storage starts.

At this time, the open / close valve 28 of the main flow path 16 is closed, the open / close valve 26 of the branch flow path 20 is opened, and water in the main flow path 16 is taken out to the branch flow path 20 via the water storage temperature raising tank 52. Steam is generated by the steam generator 32 and sent to the faucet 12 through the steam flow path 42, and steam mist is jetted toward the basin 10 from there.
The steam generator 32 performs the steam generation operation slightly after the ON operation of the switch 62.

  When the water stored in the water storage temperature raising tank 52 reaches the set temperature, the internal IH heater 58 stops the heating operation, and then the user operates the switch 62 again, so that the opening / closing valve of the branch flow path 20 is there. 26 is closed, and the opening / closing valve 28 of the downstream portion 22B in the main flow path 16 is opened, and water is supplied to the faucet 12 through the main flow path 16 this time.

  At this time, the hot water in the water storage temperature rising tank 52 that has reached the set temperature is supplied to the faucet 12 through the downstream portion 22B, and the water in the upstream portion 22A from the water storage temperature increasing tank 52 passes through the water storage temperature increasing tank 52. Via, it is supplied to the faucet 12 through the downstream portion 22B.

  Thus, even if the water in the main channel 16 located upstream from the water storage temperature raising tank 52 is residual water and cold water, the water flows through the water storage temperature raising tank 52. As a result, the water faucet 12 is always supplied with water heated to a temperature equal to or higher than a certain temperature.

When water starts to flow through the main flow path 16 (specifically, the upstream portion 22A), when a predetermined time elapses, the hot water from the water heater 14 reaches the water storage temperature raising tank 52 and flows into it.
At this time, the IH heater 58 of the water storage temperature raising tank 52 does not have to be particularly heated. Therefore, at that time (even if the detected temperature of the discharged water does not reach the set temperature), the temperature sensor 60 can detect the temperature. Based on this, the heating operation of the IH heater 58 can be stopped (however, the heating operation of the IH heater 58 can be continued until the water storage temperature reaches the set temperature).

When the user operates the switch 62 again after completing the preliminary washing with the steam mist and the main washing with the high temperature water, the supply of water to the faucet 12 is stopped there.
Therefore, the faucet 12 can be returned to the original water stop operation state by closing the operation portion 50 of the faucet 12.
However, the water stop operation may be performed by closing the operation unit 50.

According to this embodiment, it is possible to avoid discharging the cold residual water remaining in the main flow path 16 as discarded water.
The cold residual water remaining in the main flow path 16 can be guided to the water storage temperature raising tank 52 and accommodated therein, and this can be heated by the IH heater 58 and then supplied to the faucet 12. As a result, the cold residual water remaining in the main flow path 16 does not have to be drained out of the system as waste water.

  In the water discharge device of this embodiment, since it takes some time (for example, about 30 seconds) to raise the temperature of the stored water to the set temperature in the water storage temperature increasing tank 52, the water is branched into the branch flow path 20 during that time. Water is steamed by the steam generator 32 and sent to the faucet 12, and steam mist is jetted from the water discharger at the initial stage of water discharge.

Therefore, even in the water discharge device of this embodiment, it is possible to perform preliminary washing of hands and the like using the steam mist sprayed in the initial stage of use of the faucet 12.
Then, after passing through the high temperature water heated in the storage water temperature rising tank 52 or the high temperature water in the water storage temperature rising tank 52, the water in the main flow path 16 heated (mixed water) Water in the upstream portion of the temperature raising tank 52) can be sent to the faucet 12 and discharged from there for main washing.

Although the embodiment of the present invention has been described in detail above, this is merely an example.
For example, in the embodiment of FIGS. 1 and 2, a three-way switching valve can be provided at the branch portion of the branch channel 20 and the channel can be switched by the switching operation. Can be used. In addition, the water discharge device of the present invention can be provided downstream of the electric water heater in the cabinet or the like depending on circumstances. The present invention can be configured in various modifications without departing from the spirit of the present invention. is there.
