Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a shower device for squeezing water from a hot and cold water mixing valve in a shower device to an on-off valve for shower water discharge.

(Prior Art) FIG. 3 shows a conventional shower device having a large number of shower spouts. The shower device supplies hot water from a hot water supply source (not shown) to the hot water inlet of the hot and cold water mixing valve (101) through the first hot water supply passage (102), and the hot and cold water mixing valve (10) is supplied.
Hot water mixed to the desired hot water temperature in 1) is connected to the 2nd path (103a) (1
Hot water is supplied to each of the nine water discharge solenoid valves (104) via the second hot water supply passage (103) that is branched to 03b).

Each water discharge solenoid valve (104) is arranged in parallel with the drain valve (105) in a pair, and various shower water discharge ports (S ₁ ) to (S) are provided on the downstream side of both valves (104) (105). The third hot water supply channel (106) is connected to ₅ ).

In addition, a circulation path (111) for returning the hot water in the first hot water supply path (102) toward the hot water supply source is piped in front of the hot water check valve (110) of the hot and cold water mixing valve (101). .

Then, the hot water supplied from the first hot water supply passage (102) is mixed with the water in the water supply passage (107) by the hot and cold water mixing plug (101) and then supplied to the second hot water supply passage (103), and an arbitrary water discharge solenoid valve is provided. (104) is intended to be discharged from a given shower spout through the third hot water passage by opening (106) to _{(S 1) ~ (S 5} ).

The (112) provided in the second hot water supply passage (103) is a water shutoff valve, and one drainage passage (108) is branched from the downstream side of the valve (112), and the drainage passage (108) A drain valve (109) is provided on the way.

By the way, the temperature of the hot water remaining in the first hot water supply passage (102) decreases with the lapse of time after using each shower. Therefore, a person who uses the shower after a while will first take the low-temperature water remaining in the second hot water supply passage (103). As described above, in order to prevent the low temperature water in the second hot water supply passage from being discharged at the beginning of use, it is necessary to replace the low temperature water in the second hot water supply passage with a new hot water supply before using the low temperature water. is there. In the shower device described above, the hot water in the first hot water supply passage (102) is returned to the hot water supply source through the circulation passage (111) and circulated to replace the hot water, and the hot and cold water mixing tap (101) and thereafter. No. 2,
For hot water remaining in the third hot water supply passages (103) (106), the water shutoff valve (112) is closed to stop hot water from the hot and cold water mixing tap (101), and then the drainage valves (105) and ( By opening valve 109), water is drained from one drainage channel (108) and replaced with new hot water.

Note that, as described above, the replacement of hot water supply performed by draining water from one drainage channel (108) is referred to as drain water of sluice.

(Problems to be solved by the invention) However, in the above-described water draining system of the shower device, the water shutoff valve (112) is closed to stop hot water supply from the hot and cold water mixing tap. Above, the residual water in the second and third hot water supply channels (103) (106) whole system is one drainage channel (108)
It took a considerable amount of time to drain the water because it was drained from the water and replaced with a new hot water supply after this was completed.

In addition, it was not possible to spout water from any of the shower spouts (S ₁ ) to (S ₅ ) while draining water from the drainage channel (108).

The present invention is the second from the hot and cold water mixing valve to the shower opening / closing valve.
By performing the sewage water in the hot water supply passage separately and independently from the third hot water supply passage, the sewage water in the second hot water supply passage can be surely completed in a short time and immediately after the opening / closing valve for shower water discharge. It is an object of the present invention to supply hot water at an appropriate temperature and also to allow water to be discharged from a part of the shower water outlet in parallel with the slush water in the second hot water supply passage.

(Means for Solving the Problem) In order to solve the above-mentioned problems, the shower device of the present invention connects the hot water source to the hot and cold water mixing tap through the first hot water supply passage, and connects the hot water and hot water mixing tap to the secondary side. A second hot water supply passage is connected and branched into a plurality of passages, and one or a plurality of opening / closing valves are connected to these branch passages, respectively, and a third hot water supply passage connected to the secondary side of the opening / closing valve is connected. A drain valve for water is provided at the most downstream portion of each branch of the second hot water supply passage, which is connected to the shower water outlet, and the drain passage is connected to the secondary side of the drain valve to discharge the drain water. The passage was connected to the drain port at the bottom of the device.

In addition, the second hot water supply passage may be configured as a single system passage, and a drain valve for water may be provided at the most downstream portion thereof.

(Operation) According to the above-mentioned means, the shunt water system passage of the second hot water supply passage is independent, and is further divided into shunt water passages of each branch passage unit. When the temperature of the hot water remaining in each second hot water supply passage decreases after the shower has been used, the drainage valve for all the water in each branch passage is opened. Low-temperature water flows into the respective drainage channels from the most downstream part of each branch and is drained from the drainage port at the bottom of the device.

When the remaining hot water in the second hot water supply channel is drained by the respective drain valves, the hot water supply in the entire second hot water supply channel is replaced with the hot water of the appropriate temperature supplied from the hot and cold water mixing tap, and is optional for the next shower use. When the opening / closing valve is opened, it is supplied to the shower spout which communicates with the opening / closing valve through the third hot water supply passage.

It should be noted that by operating the drainage valves of the respective branch passages independently of each other, all the water in the second hot water supply passage is separately provided for each branch passage unit.

Further, in the case where the second hot water supply passage is configured as a single system passage, when the drain valve is opened, the residual hot water in the second hot water supply passage flows out independently from one drain valve and passes through the drain passage. Be drained.

(Effects of the Invention) As described above, the present invention provides the second hot water supply passage with the drain valve for sewage water at the most downstream portion of each branch passage.
The sewage water passage of the hot water supply passage is made independent from the third hot water passage, and is divided into shunt water passages for each branch passage, and new hot water is supplied from the hot and cold water mixing tap while the low-temperature water in the second hot water passage is separated. It is designed to drain water from the most downstream part of the branch road. Therefore, since the sluice system passage of the second hot water supply passage is shortened by the division, the low temperature water remaining in the second hot water supply passage is surely drained in a short time and replaced with an appropriate temperature hot water supply, and the shower It can be immediately supplied to the spout.

It is also possible to execute the sewage water in the second hot water supply path for each branch path. For example, while the sewage water in the predetermined branch path is being sprayed, the spout water is discharged from a shower spout that connects to another branch path. It is possible to do it.

In the case where the second hot water supply passage is configured as a single system passage, the number of hot water supply passages connecting the on-off valve and the shower spout decreases, but the hot water supply and all water passages can be simplified and The replacement of the hot water and the hot water in the second hot water supply passage can be surely performed as in the case where the second hot water supply passage is branched.

The temperature of the hot water in the first hot water supply path (2) is measured by the temperature thermistor (19), and the measured information is sent to the control unit.

Then, from the first hot water supply passage (2), a hot and cold water mixing plug (3)
The hot water supplied to is mixed with the water supplied from the water supply channel (10) at an arbitrary temperature by the hot water mixing valve (3) and flows into the second hot water supply channel (7).

The second hot water supply passage (7) is branched into a plurality of system passages, for example, branch passages (7a) (7b) of two system passages, and both of these branch passages (7a) (7b)
Includes a water flow sensor (14a) (14b) for measuring the flow rate of hot water passing through the branch passages (7a) (7b), a flow control valve (13a) (13b) for controlling the flow amount, and a branch passage ( 7a)
(7b) Temperature thermistor (22a) (22
b) is installed in order from the upstream side.

On one branch passage (7a) 3 single shower spout overhead showers with the _{(a 1) (a 1 -1} ) (a 1 -
2) (a ₁ -3), struck was hot water outlet _{(a 3 -1) (a 3} -

b) includes 5 for micro shower spout (a ₂ ), under shower spout (a ₆ -1) (a ₆ -2), and body shower spout (a ₄ -1) (a ₄ -2). On-off valves (8b) are connected.

And Thus, the shower _{(a 1) ~ (a 6} ) is contacted to the branch passage (7a) side of the second hot water path _{(7) (a 1) (} a 3)
(A ₅ ) and the branch road (7b) side is contacted (a ₂ ) (a ₄ )
It will be divided into two paths of (a ₆ ). For example, by opening the desired on-off valves (8 a) (8 b) one by one, the overhead shower (a ₁ ) and the body shower (a ₄ ),
Like the hand shower (a ₅ ) and body shower (a ₄ ),
The showers that connect to the different branches (7a) and (7b) are simultaneously discharged. Further, the flow rate of the hot water supplied to both branch passages (7a) (7b) is automatically opened in each branch passage (7a) (7b) by automatic control of the flow rate adjusting valves (13a) (13b). corresponding to the type of the spout _{(a 1 -1) ~ (a} 6 -2) is adjusted to the optimum flow rate.

The above-mentioned second hot water supply passage (7) is a branch passage (7
Although a) and (7b) are branched, the second hot water supply passage may be divided into two or more passages and one or a plurality of opening / closing valves may be provided in each branch passage.

Then, drainage valves (20a) and (20b) for the soot water, which are, for example, electromagnetic valves, are provided at the most downstream parts of the branch passages (7a) and (7b) of the second hot water supply passage (7). The second drainage channels (21a) and (21b) connected to the secondary side of the above are connected to the drainage channel (5) described above, respectively.

Each on-off valve (8a) (8b) and each of the shower spout _{(a 1 -1) ~ (a} 6 -2) and the third hot water passage to contact (9a)
Immediately downstream of the on-off valves (8a) and (8b) in (9b), drainage valves (11a) and (11b) for the soot water, which are electromagnetic valves, are provided, and these drainage valves (11a) and (11b) are provided. The third drainage channel (12a) (12b) is connected to the secondary side of the above, and these are collected one by one, and then the second drainage channel (21a) is connected via the common drainage valve (11c) (11d). ) (21b).

The common drainage valves (11c) (11d) are valves for preventing backflow, and drainage collected by opening the valves following the respective drainage valves (11a) (11b) to collect the second drainage channels (21a) (21b). It drains the water inside.

The under shower (a ₆ ) has its spout (a ₆ -1).
Since (a ₆ -2) is located at the bottom of the device, the
The hot water remaining in the hot water supply passage (9b) naturally flows out from the spout, so no water structure is required. In addition, the hand shower (a ₅ ) suspended on one side of the tower (A ′)
Since there is no concern that the low-temperature water discharged from the user will directly reach the user, no water structure is provided for the hand shower (a ₅ ).

Each on-off valve (8a) (8b) and flow control valve (13
a) (13b), and the first, second and third hot water supply passages (2), (7),
Drain valves (4) for each sewage provided in (9a) and (9b),
(20a) (20b), and operation control by (11a) (11b) (not shown) control unit for operating the tower body as described above (A ') center of the operation panel (a _7), whereby, the 1, first
2, 3 each hot water channel (2), (7), performs a water discharge from (9a) stearyl and water (9b), each shower spout _{(a 1 -1) ~ (a} 6 -2) There is.

Then, the temperature of the hot water remaining in the first hot water supply passage (2) gradually decreases with the lapse of time after the shower is used, but next, the showers (a ₁ ) to (a ₆ ) are used. When, the temperature in the first hot water supply passage (2) is a predetermined temperature (for example, 47 ℃ ± 3
C.) or lower, the control unit (not shown) opens the drain valve (4) without opening the on-off valve (8) to open the drainage valve (4) inside the first hot water supply passage (2). Cold / hot water is drained from immediately before the hot water supply port of the hot and cold water mixing valve (3), and discharged from the drain port (6) to the outside through the drainage channel (5).

When the inside of the first hot water supply passage (2) is replaced with new hot water supplied from the hot water supply tank (1b) as the water is made up, the temperature of the hot water in the first hot water supply passage (2) becomes the above-mentioned predetermined value. The temperature rises to the range of temperature, and the control unit which detects this by the temperature thermistor (19) closes the drain valve (4) and stops the water.

Therefore, even when the shower is reused in a state where the temperature of the hot water supply in the first hot water supply passage (2) has decreased with the passage of time, hot water of a predetermined temperature that does not mix cold and hot water can be supplied to the hot and cold water mixing plug (3). Can be immediately supplied to.

Both the branch paths (2) of the second hot water supply passage (7) continue after the hot water in the first hot water supply passage (2) is finished and the hot water supply in the first hot water supply passage (2) is maintained at a predetermined temperature or higher. If the hot water remaining in 7a) and (7b) is below the predetermined temperature (for example, 33 ° C ± 3 ° C), the drain valves (20a) (2) of both branches (7a) (7b)
0b) is opened for a predetermined time and water is drained from the second drainage channels (21a) and (21b) to replace the hot water in the second hot water supply channel (7) with hot water mixed at the set temperature.

The drain valve (20a) (20b) valve opening time described above is sufficient to replace the remaining hot water in both branch passages (7a) (7b) of the second hot water supply passage (7) with new hot water. It is determined by measuring in advance, and is about 5 seconds in this embodiment, for example.

When replacing the hot water supply in the second hot water supply passage (7), the hot water temperature in the branch passages (7a) and (7b) is used as a reference for management, and
a) It may be done by continuing the water until the temperature of the hot water in (7b) becomes equal to or higher than the above predetermined temperature.

As described above, according to the slag water structure of the second hot water supply passage (7) in the shower device (A), the slop water system passages of the second hot water supply passage (7) are respectively the third hot water supply passages (9a) (9b). ) Is independent from each other and is divided into all water channels of each branch channel. As for the fresh water, the residual low temperature water in the second hot water supply passage (7) is separately supplied from the most downstream parts of both branch passages while new hot water is supplied from the hot and cold water mixing tap (3). It is possible to reliably replace the residual low-temperature water in (7) with hot water of a suitable temperature in a short time, and immediately supply the water after the on-off valves (8a) and (8b).

Further, the control and management of the sewage water operation in the second hot water supply passage (7) is based on the hot water temperature management using the temperature thermistors (22a) and (22b) and the hot water supply time management by the timer of the control unit (not shown). There is an advantage that it can be surely performed by a relatively simple means.

The hot water remaining in each of the third hot water supply passages (9a) and (9b) after the use of each shower (a ₁ ) to (a ₆ ) is the shower spout (a ₁₎ used each time the shower used is stopped. -1)
~ (A ₆ -2) drain valve (11a) (11b) and (11c) (11
Open d) to drain water from the third drainage channel (12a) or (12b) and leave the third hot water supply channel (9a) (9b) empty. Therefore, when the shower water outlet is used next time, the hot water having the set temperature in the second hot water supply passage (7) can be discharged as it is.

Thus, in the shower device according to the present embodiment, the residual low-temperature water in the second hot water supply passage (7) is watered in a short time,
It is possible to immediately supply hot water suitable for each opening / closing valve (8a) (8b) and thereafter. At the same time, the sewage water in each of the third hot water supply passages (9a) and (9b) can be individually supplied independently of the spill water in the second hot water supply passage (7), so that each shower (a _{When the} steps ₁ ) to (a ₆ ) are repeatedly used, the remaining hot water in the third hot water supply passages (9a) and (9b) can be drained by each shower that has been used up. It is possible to immediately discharge hot water of an appropriate temperature.

In the above embodiment, the drain valves (20a) (20b) of the respective branch passages (7a) (7b) are simultaneously opened so that the branch passages (7a) (7b)
Although all the water in b) was drained at the same time, the drain valve (20a) (20
By controlling b) separately, it is possible to separately execute all the water in the second hot water supply passage (7) for each branch passage (7a) (7b). If only the hot water supply in 7a) is at a low temperature below a predetermined level, only the drain valve (20a) should be opened independently and the water in the branch passage (7a) should be drained to the other branch passage (7a). Contact shower (a ₂ )
It is also possible to discharge water from (a ₄ ) (a ₆ ).

The second hot water supply passage in the above-mentioned shower device may be configured as a single passage without branching, and a drain valve may be provided at the most downstream portion thereof. When the second hot water supply passage is configured as a single system passage, there is only one hot water supply passage to which the on-off valve and the shower spout can be connected, which limits the size of the pipes and shower spout water. The water passage can be simplified, and further, the replacement of the hot water with the hot water in the second hot water supply passage can be surely performed as in the case where the second hot water supply passage is branched as described above. .
