Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply piping system having an on-off valve centralized operation mechanism, and a centralized on-off valve operation mechanism in a water supply piping system.

[0002]

2. Description of the Related Art A converging portion is formed by collecting pipes intensively at one place, and a header having a structure for supplying tap water by dividing water from the converging portion to each water-using device is installed under the floor. There is known a piping system using a header method in which a header is directly connected to a water-using device by a single synthetic resin water pipe, and a pipe connection is not performed between the pipes.

[0003]

However, the header method using such a header still has the following problems.

[0004] That is, the terminal water outlet at the end of the water distribution pipe distributed from the header is connected to a water-using device, but such connection work must be performed by a construction worker on site, and the connection cannot be easily performed. There is, in particular, every time the replacement of the water use equipment must be connected to the terminal water outlet, this connection work can be configured to be connected with one touch, but at the time of the connection work The water pipe is placed in a predetermined position, for example, a water faucet provided at a terminal water spout, and is stopped and connected once, then the water faucet is opened and water is spouted to send water to the water use equipment. It is necessary to operate a faucet, such as connecting a gas appliance to an indoor outlet of a gas pipe or connecting an electric appliance cord to a power outlet like a normal gas outlet or power outlet. Conveniently water use through to connect the instrument to the branch pipe water, did not constitute the structure performs waterproofing.

[0005] In addition, if there is an unused diversion pipe that is not supplied for a long period of time among a large number of diversion pipes derived from the header, which is a junction of pipes, the tap water in the pipe rots, and various bacteria enter the unused diversion pipe. There is a possibility that the bacteria may occur, and the bacteria may flow into another water pipe and become unsanitary.

On the other hand, Japanese Patent Laid-Open No. Hei 4-254628 discloses a technique in which a switch provided near an end water outlet operates an electromagnetic on-off valve provided at a start end of a water pipe.

In this case, since the operating means for operating the on-off valve are respectively arranged near the water outlet at the end of the water pipe, the operation of the on-off valve is performed at the end of the water pipe having the predetermined operating means. There was a drawback that it was necessary to go to the spout, and the centralized control of each open / close valve of the water distribution panel could not be performed.

[0008] In addition, the water outlet end of the water pipe is not provided with the idea of easily connecting or disconnecting a water-using device like an indoor outlet of a gas appliance or a power outlet of an electric appliance. It is not a technique specific to water use equipment and water supply, for example, a technique in which a water outlet end of a water pipe opened indoors automatically stops water when a water supply pipe of a water use equipment is detached.

As described above, conventionally, in the case of supplying electricity to a house, the supply of electricity to each power outlet can be centrally managed by a switchboard installed at a required position indoors. Therefore, when leaving home for a long period of time, the power supply to the power outlets can be cut off by using the switchboard to prevent accidents such as electrical leakage from electrical appliances. In the case of water supply, it is not configured so that the supply of water from the water pipe to each water-using device can be centrally managed.To shut off the water supply to each water-using device, If water stoppage is required at the water outlet that leads to the water use equipment, the operation becomes complicated, and if water leakage occurs in the water use equipment if the water stop operation is forgotten and left for a long time, Pollutes the house by the leak It was there.

Furthermore, the technique disclosed in the above-mentioned publication controls the opening and closing valves at the start of the water pipe at the water outlet at the end of each water pipe, so that the flow control operation positions are dispersed at various locations. It becomes the terminal water outlet, and it is therefore difficult to easily perform relative flow adjustment such as preferentially selecting the terminal water outlet that should give priority to securing the flow rate from the terminal water outlets and reducing the flow rate of the other water outlets. .

Also, since the flow path from the on-off valve to the terminal water outlet is in an open state, there is a possibility that backflow of sewage may occur. It was not possible to prevent the invasion of various bacteria and lacked the feasibility. In other words, it is necessary to sufficiently consider that the water supply equipment is formed with hygiene considerations and must not impair hygiene.

[0012]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a header for forming a merging portion by concentrating and merging the starting ends of flexible water pipes respectively piped to a water-using device at one location. A water supply pipe was connected to the header, and an on-off valve was provided at the start end of each of the diversion pipes branched from the header, and on-off valve operating means for operating each on-off valve were intensively arranged at predetermined positions. It is another object of the present invention to provide a water supply piping system having a centralized operation mechanism for an on-off valve.

[0013] Further, a water pipe connected to a water pipe of a water-using device or a water outlet for connecting to the water pipe is connected to a diversion pipe branched and piped from the header. Connect a water discharge section that is configured to automatically flow water to the water distribution pipe by the connection operation of the water supply pipe, and to automatically stop water by removing the water supply pipe, and adjust the water discharge amount to the water separation pipe branched from the header. Connecting a water discharge section configured so as to be adjustable, an on-off valve provided at the beginning of each diversion pipe branched and piped from the header has a flow rate adjustment mechanism, and further, the beginning of each diversion pipe branched and piped from the header The on-off valve provided in the section is configured so that the flow rate can be adjusted, and the on-off valve operating means for opening and closing the on-off valve is centrally arranged on the operation panel, and at the end water outlet of the diversion pipe Water discharge adjustment Operating means, and remotely controlling the on-off valve operating means provided centrally on the operation panel by radio signals from the water discharge amount adjusting operation means, adjusting the flow rate of the on-off valve having the flow rate adjusting function, and discharging the water from the terminal water outlet. It has a feature in that it is configured so that the amount of water can be adjusted.

Further, according to the present invention, the headers of the flexible water diversion pipes respectively piped to the water use equipment are concentrated and merged into one place to form a header which becomes a junction, and the water supply pipe is connected to the header. In addition to the connection, an on-off valve is provided at the start end of each diversion pipe branched from the header, and an operation panel on which the on-off valve operating means of the on-off valve is centrally arranged is arranged at a predetermined position. And a centralized operation mechanism for the on-off valve in the water supply piping system.

The present invention is also characterized in that a main switch for closing all on-off valves provided at the starting end of each water diversion pipe branched from the header is provided on the operation panel.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, tap water supplied from outside through a water supply pipe is supplied to a header which is a junction of a water distribution panel installed indoors.

Then, tap water is branched and sent from the junction in the water distributor to each terminal water outlet via a flexible water distributor.

The water distribution pipe is laid from the water distribution board to the ceiling, the wall, or under the floor, and is connected to the water discharge part with a small number of connection parts.

(Structure of water discharge section) A coupling board having a water discharge pipe as a water discharge section is provided at an end water discharge port of a water distribution pipe branched from a header, and the coupling board has a water supply pipe for water sprinkling. And a water pipe connected to a toilet tank, a local washing and drying device, a mixing faucet for a bathroom, a dressing table, a kitchen, and a water-using appliance such as a washing machine, are detachably connected. The coupling board is configured to allow the coupling board to pass water, and the coupling board is automatically stopped when the water pipe is removed. Alternatively, the water pipe can be attached and detached by a simple operation as another embodiment. Or as another embodiment, the terminal water outlet of the water pipe has a water discharge amount adjusting operation means like a faucet, or,
As another embodiment, the water discharge part provided at the end water discharge port of the water distribution pipe may be provided with a water discharge amount adjustment operation means for transmitting a wireless signal to an on-off valve operation means for operating an on-off valve of the water distribution pipe. .

(On-off valve and its operating means) On each branch of the water distribution panel, an on-off valve is provided, and the on-off valve is closed by an on-off valve operating means provided centrally on the operation panel. By doing so, the inside of the diversion pipe that has been stopped at the end water outlet of the diversion pipe and the other diversion pipe are cut off, and there is no exchange of water, so if the water use equipment is not used for a long time, Even if the water rots and germs are generated, if the water is stopped at the branch of the water pipe, the germs will not flow back and be mixed into another water pipe through the junction or the junction.

In addition, by closing the on-off valves at the branch portions of the water distribution board, even if the water-using equipment breaks down when the water-using equipment is not used for a long period of time, the water-using equipment is inadvertently prepared. Since water is not passed through the house, water leakage does not occur in the water use equipment and the house is not polluted.

Further, since a water pipe such as a water-using device can be connected to the coupling board with one touch, when the water-using device is not used for a long period of time, the water-using device such as a faucet fitting is coupled with the water pipe. It is also possible to remove them from the ring machine and store them separately, thereby prolonging the product life of the water pipes and the water use appliances.

As described above, when the water stop operation is performed at the terminal water discharge port of the water distribution pipe and then the on / off valves provided at the respective branch portions of the water distribution board are closed, the on / off valve operating means is provided intensively. Since the on-off valve is operated by the operation panel, the water supply can be centrally controlled by the operation panel as in the case of the conventional power distribution panel. It is possible to provide a new and new form of water supply piping system.

The following modes are conceivable as operation modes of the on-off valve.

That is, in the first embodiment, the on-off valve operating means provided intensively on the operation panel disposed at a predetermined position, for example, the on-off valve is constituted by an electromagnetic valve, thereby concentrating the operation panel. The provided switch and each solenoid valve are electrically connected to each other, and the on-off valve can be opened and closed by electrically operating the solenoid valve by operating a switch in the operation panel.

In the second mode, the on-off valve can be mechanically operated by operating a remote lever via a wire interlockingly connected between the lever and the valve shaft of the on-off valve. .

As described above, the operation panel is provided in a place where the occupancy frequency is high indoors, and the on-off valve operation means for operating the on-off valves provided at each branch of the water distribution panel in the operation panel. The on-off valve operating means are remote levers and are connected to the valve shaft of the on-off valve via wires and are operated mechanically by operating the remote levers centrally arranged in the operation panel. The on / off valve is operated.The on / off valves provided at each branch of the water distribution panel are each constituted by an electromagnetic valve. Electrically conducting switches are provided in a concentrated manner, and a predetermined switch is used to open and close a predetermined on-off valve.

Further, the on-off valve may have a flow control function in addition to the simple on-off function, and the on-off operation and the flow control operation of the on-off valve having the flow control function are arranged at predetermined positions. It can be configured so that it can be performed by the on-off valve operating means provided centrally on the installed operation panel, and the water discharge amount adjustment operation means provided at the end water outlet of the water separation pipe concentrates on the operation panel with a radio signal The on-off valve operating means provided in a specific manner may be configured to be remotely controllable. In this case, the simple closing operation of the on-off valve is performed by the on-off valve operating means of the operation panel, and when the desired water discharge amount is adjusted in the vicinity of the terminal water outlet of the water separation pipe, the on-off valve operating means is operated by a radio signal. The required amount of water discharged from the water pipe can be obtained by remotely controlling the on-off valve having a flow rate adjusting function at the start end of the water pipe. In addition, by operating one of the open / close valves of each water pipe, it is possible to secure the water discharge amount preferentially to the necessary water use equipment among the water use equipment in each place. The water discharge priority can be easily set within the specified water discharge capacity range.

That is, there is a limit to the water supply capacity supplied to the house, and in order to effectively supply water to each water use appliance within this limited range, water supply directly to the human body is preferentially supplied. It is desirable that priority be set to restrict other water supply.

Therefore, the on / off valve having the flow rate adjusting function is configured to be operated by the on / off valve operating means intensively provided on the operation panel disposed at a predetermined position, and the discharge provided at the terminal water discharge of the water separation pipe. The flow rate of the on-off valve of the water distribution pipe can be controlled from the operation panel or from the water discharge amount adjustment operation means by making it possible to remotely control the on-off valve operation means provided centrally on the operation panel by a radio signal from the water amount adjustment operation means. By performing the adjustment, the above-mentioned preferential water supply can be performed.

Furthermore, it is difficult to equally apply the amount of water and the water pressure to each house as the fate of tap water, and the amount of water and the water pressure vary depending on the location of the water use equipment. For this purpose, the above-described priority water supply technology of the present invention can be used.

(Operation panel) The operation panel 100 has a centralized arrangement of on-off valve operating means 101 for operating an on-off valve 79 provided at the start end of each of the water pipes 13 branched and piped inside the water distribution board 6. By performing the opening and closing operation of each on-off valve 79 by each on-off valve operating means 101, it is possible to centrally manage the supply of water with the operation panel 100 in the same sense as the distribution panel in the electric supply. You can do it.

The operation panel 100 is installed in a place where the frequency of living indoors is high, for example, in a kitchen, living room, entrance, or the like. As shown in FIGS.
A switch 1 as an on-off valve operating means 101 electrically connected to an electromagnetic valve as an on-off valve 79 provided at the start end of each water pipe 13
02 and the switches 102 and power supply 1
The main switch 104 is provided between the main switch 104 and the main switch 104. In the figure, 1
05 is an electric wire for connecting the on-off valve 79 and the switch 102.

When each switch 102 is turned on while the main switch 104 provided on the operation panel 100 is turned on, an on-off valve (solenoid valve) 79 corresponding to the switch 102 is opened to connect to the water pipe 13. When the switch 102 is turned off, the on-off valve (solenoid valve) 79 is closed, and the water supply to the water pipe 13 is stopped. Moreover, when the main switch 104 is turned off, all of the on-off valves (solenoid valves) 7 regardless of the state of each switch 102

It is not necessary to move to the water distribution board 6 and the terminal water discharge port 73 of each water pipe 13 to operate the on-off valve, and the on-off valve 79 is centralized by the operation valve 100. In this way, the water supply can be centrally managed by operating the water supply system in a centralized manner, and the water supply piping system 1 can be a new form of the water supply system, which is a completely new concept of the existing water supply.

Further, since a plurality of on-off valve operating means 101 are arranged in a concentrated manner on the operation panel 100, any one of the water diversion pipes 13 can shut off the water simply by looking at the on-off valve operation means 101 of the operation panel 100. It can be easily confirmed whether or not the state is established.

Further, since the plurality of on-off valve operating means 101 are arranged in a concentrated manner on the operation panel 100, a controller is provided on the operation panel 100 on which the plurality of on-off valve operating means 101 are centrally arranged. It is easy to configure the on-off valve operating means 101 to be controlled collectively by the controller.For example, when a large amount of hot water exceeding a predetermined amount is used in the hot-water mixing tap 11 for a bathroom. The water supply to the washing machine 68 is stopped by closing the on-off valve 79 at the start end of the water pipe 13 communicating with the water faucet 9 for the washing machine, and the water supply to the hot / water mixing faucet 11 for the bathroom is prioritized. Priority can be given to direct water supply directly to the human body, such as to be able to control so as not to cause discomfort to the user of the bathroom, while limiting other water supply. Limited, supplied to the house Water can be effectively supplied to each water-using device within the range of water supply.

Further, since each on-off valve 79 can be closed by the on-off valve operating means 101 disposed on the operation panel 100, for example, when nailing is performed on a wall, the nail is erroneously inserted to the water pipe 13 as well. Even in the case where water is leaked due to striking, only the on-off valve 79 provided at the start end of the water pipe 13 needs to be closed, and repair of the water leakage is performed while using other water-using equipment. be able to. If one water-using device is not used for a long period of time, closing only the open / close valve 79 at the start end of the water-dividing tube 13 that leads to the water-using device can temporarily prevent the unused water-dividing tube 13 from being used for a long time. Even if the water inside the rot decomposes and germs propagate, the germs do not flow into other water pipes 13 and can be used hygienically.

In this embodiment, an electric switch 102 is used as the opening / closing valve operating means 101, and the switch 102 and the opening / closing valve 79 are connected by the electric wire 105. It can be connected by wireless communication.
A lever is used as the opening / closing valve operating means 101, and the lever as the opening / closing valve operating means 101 is mechanically connected to the opening / closing valve 79 by interlockingly connecting the lever to the valve shaft of the opening / closing valve 79 using a push-pull wire. You can also.
