-Hereinafter, the configuration and water saving principle of the washbasin faucet water saving device according to the present invention will be described in detail with reference to the accompanying drawings.

-The main difference between water and air, which is a major difference from other technologies in the technology of realizing the effect of saving water while mixing water and air, which is the basic principle of the technology applied to the water-saving device 100 of the wash basin faucet for the present invention The basic principle of the air intake noise prevention technology that completely prevented the occurrence of air intake noise is as follows.

One narrow air passage communicating with the atmosphere is formed at one end of the hollow inner pipe which is completely sealed to the outside, and is uniformly spaced between the pipe while completely enclosing the pipe in a sealed state with the atmosphere outside the pipe. A separate hollow outer pipe is provided to have a level volume, and a narrow air inlet and outlet is formed at one end of the inner pipe to allow air to flow between the inner and outer pipes, and to communicate with the atmosphere at the other end of the outer pipe. After securing the narrow air passages, insert the barrel into the air passage of the external pipe communicating with the atmosphere, and push the barrel into a certain depth in the direction of the inner pipe, and then use the vacuum pump as a part of the air outlet passage of the internal pipe communicating with the atmosphere. Air is drawn into the air inlet passage in communication with the atmosphere of the external pipe. It can be seen that the suction noise of the machine is significantly reduced in the state of inserting the barrel to a certain depth than when the barrel is not inserted.

The above phenomenon is a common phenomenon regardless of the size or shape of the hollow pipe, and if it is not inserted, the air sucked into the air inlet of the outer pipe is spread evenly throughout the space between the outer pipe and the inner pipe. As a result of the resonance, noise is generated to a certain level. However, when the air outlet is plugged into the inner pipe through an air passage communicating between the outer pipe and the inner pipe in a state in which air is evenly spread throughout the space between the outer pipe and the inner pipe. After being introduced, the inner pipe is not connected to the air passage of the inner pipe. Instead, the air flows only in the space between the inner end of the barrel and the inner pipe, and the inner pipe communicates between the outer pipe and the inner pipe. To a group of air passages communicating with the atmosphere of internal pipes As the air escapes, it can be confirmed through a simple experiment that the noise generated by the resonance phenomenon appears as the air is evenly spread throughout the space between the outer pipe and the inner pipe.

In other words, the air flowing in and out of a certain space is spread in a space having a certain volume, and the inflow pressure is reduced to a certain level. The noise can be suppressed to a certain level by the above-described decompression device.

-The present invention uses the above-described principles of natural phenomena, and when using the water-saving device using the device of the present invention without the noise reduction device as described above, air intake noise such as air intake noise of the jet engine is generated, but When using the air intake noise prevention device such as can prevent the occurrence of the air intake noise as described above, the air intake noise prevention device serves as a noise reducer such as the role of a muffler to reduce the noise of automobile exhaust gas Do this.

-The overall configuration principle of the water-saving device 100 of the present invention washbasin flush faucet to prevent the occurrence of noise due to air intake using the above principles With reference to the accompanying drawings will be described in more detail.

The water-saving device 100 of the present invention is connected to the discharge port 30 of the washbasin 10 flushing faucet 20 by the connection part 39, and compresses water in the traveling direction of the flow channel 31. The tube 32 is formed,

-The water flowed through the compression pipe 32 is reduced in diameter and the flow rate is rapidly increased at the same time as the water saving, the flow velocity is maximized at the end of the compression pipe 32 in a direction that is in line with the water flow direction The pressure is lowered among the various components of the water-saving device 100 of one example, the conditions for inhaling the air in the atmosphere is formed by the effect of the pressure lower than the atmospheric pressure, the compression tube 32 is reduced pressure At the end of the air through the air inlet 34 formed at right angles to the compression tube (32) is mixed with water passing through the compression tube (32) in a state where the flow rate is higher than before the air is introduced By flowing in the direction of the discharge pipe 35, the water pressure is prevented from being lowered due to water saving by mixing water and air through air suction, and the flow rate of water discharged by the pressurizing effect of the suction air is increased. Sense of pressure may be elevated, such as to implement the effect of the pressure of the water saving effect at the same time being.

-In the case of the air-mixed water saving method through the compression as described above, even in the case of low water pressure lower than the normal water pressure compresses the water flowing through the compression pipe 32 to a certain level, the pressure according to the flow rate rise in the compression portion Since the pressurization effect is obtained through the inflow of atmospheric air due to deterioration and the mixing of the inflow air and water, the foam form has a plurality of net forms commonly used as water-saving devices in a general washbasin 10 and a washing faucet 20. When using the water saving device 43 for discharging the water at a low water pressure as described above, the water pressure of the discharged water is too low to solve the problem of using the water properly through the water saving device 100 of the present invention.

-With reference to the accompanying drawings a preferred manufacturing method of the present invention washbasin flush faucet water saving device 100 utilizing the above principle Explain

-In the case of the water saving device 100 according to the present invention, the device is used in general water pressure not high pressure, and the material of the present device is made of a plastic material used in the manufacture of a conventional shower since the manufacture of components is usually performed by injection. You can also use

-The present invention has a water-saving part (200) consisting of one body and a separate decompression tube (33) and a decompression tube (33), which is inserted into the air intake and noise prevention air inlet pipe (36), waterproof ring It consists of 40 and the waterproof packing 41. As shown in FIG.

-In the case of water-saving part 200 is produced in the form of one injection, the connection part 39 is a part for connecting the water-saving device 100 of the present invention to the discharge port 30 of the washbasin (10) flush faucet 20, the Since the discharge port 30 is basically machined with a female screw, the discharge port 30 is formed of a male screw engaged with the female screw of the discharge port 30. However, when the discharge port 30 is formed with a male screw, the discharge port 30 should be processed with a female screw. Depends on the screw form, the shape of the connection portion 39 is not essential in the present invention, it is sufficient that only the shape that can attach the water-saving device 100 of the present invention to the discharge port (30).

-In the case of the coupling part 38, the water is finally discharged by mixing with the air through the water-saving device 100 of the present invention and pressurized water, if necessary, separate water, such as a conventional water-saving device 43 The female screw was formed with the internal space empty so that the spraying device could be installed by screwing, etc. The specification of the female screw is to be matched to the specification of a separate water spraying device to be attached to the female screw part. If the coupling portion of the separate water jetting device to be attached to the coupling portion 38 is formed of a female screw, the coupling portion 38 has an internal volume level when the coupling portion 38 is a female screw. Processed as a male screw while maintaining the shape of the coupling portion 38 is not a key point in the present invention, it is sufficient that only a form that can be attached to a separate water injection device

-Compression tube 32, discharge tube 35, and coupling portion 38 is in the form of a right-to-left movement in a straight line, so post-processing is required through the injection process in a state that is set to a predetermined value in consideration of the shrinkage rate at the time of injection. It is also possible to manufacture the finished form without the waterproof ring insert groove 37 for inserting the waterproof ring 40 and the connection part 39 screw portion formed with the compression pipe 32 therein is also commonly used in the conventional injection method Since the technology is a separate description of the manufacturing is omitted.

-In the case of the waterproof ring 40, the water-saving water device 100 is leaked by the effect of the waterproof ring 40 when the water-saving part 200 is inserted into the pressure-sensitive tube 33 and coupled as shown in FIG. Since it serves to prevent the to be surely to be configured at both ends of the water-saving portion 200 in contact with the decompression tube 33 as shown in Figure 4, in spite of the Figure 4 a plurality of at each end The waterproof ring 40 may be provided.

4, in the case of the air suction port 34 configured to be in communication with the decompression unit 42 at a right angle with the compression pipe 32 at one end of the end of the compression pipe 32 in the flow channel 31 direction, as shown in FIG. Since it is a part which abuts the end surface of the compression pipe 32 and the discharge pipe 35, the residue of injection remains in the said contact part because of the structure of injection molding, The cross section of the compression pipe 32 and the discharge pipe 35 and When there is foreign matter in the part of the air inlet 34 which is in contact with the air inlet 34, a part of the water that has passed through the compression tube 32 is separated from the air inlet through the air inlet 34. Since the air inlet 34 can be flowed back to the air inlet 34 in the form of a water splash phenomenon, the air inlet 34 which is in contact with the end face of the compression pipe 32 and the discharge pipe 35 through a drilling operation after injection. It is necessary to completely remove foreign substances in the) part.

Compression tube 32, discharge tube 35, air inlet 34 portion of the structure must be circular only to prevent the reduction of water pressure in proportion to the water savings, which is a feature of the present invention as described above In spite of saving water, it does not maintain the characteristics that the discharge water pressure rises to a certain level, and the configuration of the front, rear, left and right isomorphic shape such as square where pressure acts uniformly may be used. It is the best.

While being in communication with the atmosphere at one end of the pressure reducing tube (33) is formed to a certain depth to the decompression unit 42 to prevent the generation of air intake noise during air intake while introducing the outside air into the decompression unit 42 Air intake noise is prevented to maintain the induction pipe shape so that the introduced air is introduced into the compression tube 32 through the air inlet 34 and mixed with the water compressed by the compression tube 32 is discharged to the discharge tube 35 In the case of the combined air inlet pipe (36) is the most suitable to be inserted separately into the grooves drilled in one end of the pressure reducing pipe (33) due to the nature of the coupling with the pressure reducing pipe (33) and coupling to the pressure reducing pipe (33) The position of the position is not an important point of the present invention as long as it does not interfere with the communication with the decompression unit 42.

-In the case of the water-saving unit 200, the water-saving unit 100 is shown as a circle in the water-saving device 100 of the present invention shown in FIGS. 1 to 9, but there is no problem in implementing the characteristics of the internal components described above. (200) The form of appearance is not an important key point of the present invention.

6 and 7 in the case of attaching the existing water-saving device 43 of the net form to the water-saving device 100 of the present invention shown in Figure 6 is not essential and whether each user or manufacturer is cooking as needed Although the shape, shape, size, etc. may not be specified even when using the combined water-saving device 43 as described above, the water injection from the water-saving device 43 is not required. The size of the cross-sectional area is characterized in that it is necessarily formed larger than the size of the cross-sectional area of the compression tube (32).

In the case of the attachment of the water-saving device 43 of the existing mesh type attached to the coupling portion 38, the size of the total cross-sectional area of the injection hole in which water is injected from the attachment is determined by the cross-sectional area of the compression pipe 32. When the size is less than or equal to the size, depending on the degree of water pressure or the flow rate drawn in, in some cases, the attachment causes a braking effect, so that the total amount of water passing through the compression pipe 32 cannot be discharged. In some cases, since the air is discharged to the outside through the air inlet pipe 36 of the combined use of inhalation noise prevention, it is necessarily characterized in that the compression pipe 32 is formed to be larger than a certain level.

In the present invention, when the inner diameter of the discharge tube 35 is not larger than the inner diameter of the compression tube 32, water passing through the compression tube 32 generates a braking effect in the discharge tube 35, and thus, the air suction port 34 and Since the phenomenon of reverse ejection in the direction of the air inlet pipe 36 combined with the air intake and noise prevention appears, the inner diameter of the discharge tube 35 is necessarily formed to be larger than a predetermined level larger than the inner diameter of the compression tube 32.

The ratio of the size of the discharge tube 35 to the compression tube 32 is proportional to the size according to the degree of water pressure flowing into the compression tube 32, the desired water saving rate, and the desired pressure ratio. In all cases, the inner diameter of the discharge tube 35 is necessarily larger than the inner diameter of the compression tube 32 in any case.

-The size of the appropriate decompression unit 42 has been determined through a number of experiments, but there is a certain level difference depending on the degree of water pressure introduced into the water-saving device of the present invention. 10 to 20 times the size of the sum of the volume of the inner diameter of the discharge tube 35, more preferably the size of 12 to 16 times the most preferred size is 14 times.

-The size of the inner diameter of the noise prevention combined use air inlet pipe 36 communicated to the outside from the pressure reducing pipe 33 communicates with the pressure reducing unit 42 to reduce the pressure reducing unit 42 through the air inlet pipe 36 for noise prevention combined use. ) Is preferably a certain level larger than the size of the inner diameter of the air inlet 34 to suck the air introduced into the compression tube 32, and more preferable cross-sectional area is about 2-5 times the size of the cross-sectional area of the air inlet 34. In summary, the test results of various cases show that the most preferable inner diameter of the air inlet pipe 36 for preventing air intake and noise at the normal water pressure (1.5 to 2.5 bar) level is 3.3 times the size of the inner diameter of the air inlet (5). Level.

The degree of depth for inserting the air inlet pipe 36 for preventing air intake and noise from the pressure reducing tube 33 into the pressure reducing unit 42 is determined between the distance between the pressure reducing tube 33 and the outside of the compression tube 32. Although 1/2 ~ 3/4 degree is preferable, various test results of various cases are summed up, and at the normal water pressure (1.5 ~ 2.5 bar) level, the distance between the pressure reducing pipe 33 and the compression pipe 32 outside It is most preferable to form the air inlet pipe 36 for both the air intake and noise prevention in the direction of the compression pipe 32 up to a depth of 2/3.

-The size of the compression pipe 32 varies in size depending on various variables such as the amount of water drawn in, the amount of water to be discharged, the water pressure of the water drawn in, and the target water saving rate, which cannot be specified. It is necessary to decide in consideration of this.

-When the ratio of the length of the compression tube 32 and the discharge tube 35 is a combination of the test results of various cases, there is a certain level difference depending on the degree of water pressure introduced into the water saving device of the present invention, but the ratio of the preferred length is the discharge tube The length of the discharge tube 35 is 1.5 to 3.5 times the length of the compression tube 32, but at the normal water pressure (1.5 to 2.5 bar) level, the length of the discharge tube 35 is 2-3 to the length of the compression tube.
