Abstract

<P>PROBLEM TO BE SOLVED: To save resources and increase convenience by detecting the physical and chemical properties of a fluid inside a fluid (gas, liquid, powder, etc.) carrying pipe and discharging the fluid out of a set condition range into a bypass part and by immediately using the fluid output from a faucet with optimal condition. <P>SOLUTION: A sensor for the properties of the fluid and a fluid path switch part are provided just near the faucet inside the fluid carrying pipe and when the sensor detects the deviation from the set condition, the fluid is discharged into a fluid path with different properties through the bypass part. When the sensor detects the set condition, the fluid is directly discharged into the faucet. Thereby, the fluid with the set condition can be immediately obtained from the cock. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

The present invention detects the physical and chemical properties of the fluid in the fluid (gas, liquid, powder, etc.) conveyance pipe, discharges the fluid outside the set condition range to the bypass section, and the fluid output from the faucet is in the optimum condition. Regarding making it available immediately.

The case where the fluid transfer pipe is a hot water supply pipe will be described.

When the part A where hot water is stored or generated by cogeneration and the faucet B installed at the location where the hot water is used has a certain distance, the user of the hot water will try to receive hot water after a certain period of time has elapsed since the previous use. Then, since the temperature in the pipe between AB is lower than the necessary temperature, if at least the remaining portion is not discharged, hot water of the necessary temperature cannot be obtained, and the water must be discarded in advance. It was.

In some cases, additional water had to be discarded until the piping warmed above a certain temperature.

For example, if you try to raise the temperature of a bath tub that has fallen during bathing, if you add it to the bath tub without discarding the lowered temperature, cold water will enter first, and the temperature of the tub will increase further. When we tried to raise the temperature, including the amount that it fell, it required a lot of hot water, wasted energy, water resources and time, and was not good for health.

Further, in the method of Japanese Patent Application No. 2000-359790 (P2000-359790), the amount of hot water used by the user of hot water at a time is very small, and the time until the temperature of the pipe between AB is lower than the set temperature is exceeded. When used frequently every time, the tank capacity is theoretically infinite and unsuitable for realistic installation.

Furthermore, in order to mix cold water with hot water, if a mechanism is used that adjusts the temperature by mixing with cold water at the faucet, or if the required set temperature is high, the tank water cannot be recovered. Sometimes it was.
Japanese Patent Application Laid-Open No. 2002-162119 (P2002-162119A) Japanese Patent Application No. 2000-359790 (P2000-359790)

The present invention detects the physical and chemical properties of the fluid in the fluid (gas, liquid, powder, etc.) conveyance pipe, discharges the fluid outside the set condition range to the bypass section, and the fluid output from the faucet is in the optimum condition. By making it available immediately, the purpose is to shorten the time required to secure the required fluid and to save resources and energy. Taking a hot water supply system as an example, if there is a faucet at a position away from the water heater, cold water will flow out for a while after opening. A large amount of cold water until it is changed to hot water is washed away. In addition, the change from cold water to hot water cannot be detected visually or the like, and it is bothersome to check each by hand, resulting in discomfort such as irritation.

In order to achieve the above object, in the method of the present invention, the sensor 20 and the liquid path switching unit 30 for detecting the physical and chemical properties of the fluid in the immediate vicinity of the tap B in the fluid conveying pipe, the temporary outflow of the fluid outside the set conditions First, the bypass unit 40 and the path 50 for sending fluid from the bypass unit have a basic structure, and in some cases, the units 40 and 50 may function as a single unit.

20 is set immediately before B as much as possible between the faucet B from the fluid supply source A in the pipe 10 (the pipe 11 from A to 20 (30), the pipe 12 from 20 (30) to B). ) Depending on the setting conditions, 30 is interlocked, and if the condition is not satisfied, the valve in the 20 direction is closed and the valve in the 40 direction is opened. If the condition is satisfied, the reverse operation is performed.

The structure of 40 adopts a method in which 40 becomes higher than 50 using power 41, gravity 42, pressure 43 in the temporary storage tank, or the like as a method of sending fluid in the 50 direction.

As an example of the structure 43, a pipe 432 is connected to 50 downward from the lowermost end of the sealed tank 431, and a discharge port 435 is provided at a position higher than both the highest liquid level 433 and the lowest liquid level 434 in the 431. 30 with pipe 436. Above 433 to 434 is filled with a compressible fluid 437 that does not cause an unexpected change in the fluid in the piping.

50 is allocated to one or more of pipes 521 connected to pipes 511, 50 connected to pipes for sending fluid to A, pipes 521 dedicated to fluids under conditions of 50, etc. It has a function and may be omitted in some cases.

When B has a mechanism that can mix the fluid of 11 and the fluid discharged from 50, it may be sent directly from 50 to B.

If possible and necessary, a function of changing to the discharge condition from B is added to either or both of 12 and B.

By using the present invention, the fluid coming out of the faucet B is a set condition from the beginning, and the trouble of extracting and discarding the fluid that does not satisfy the condition is reduced, which saves resources and improves convenience.

Since fluids with setting conditions are output from the beginning, troubles such as changing the setting conditions by users who are uneasy about the setting conditions by the time the setting conditions are reached are reduced, improving economy and safety. Contribute.

The conditions of the sensor 20 are set.

Whether faucet B is in use or not (setting changeable), 20 knows the fluid conditions, and if the conditions are not met, 30 is switched and fluid is passed to 40.

When 20 knows that the condition has been met, it switches 30 and flows fluid to B, allowing the user of the supply system to use it normally.

The fluid that does not satisfy the condition and flows to 40 is processed as in 0009 to 0013.
