Description

Water Saving Kit {Water Reducing Kit}

The present invention relates to a water-saving kit, and in particular, it is installed inside the water pipe of a faucet for a kitchen or bathroom washbasin to reduce the cross-sectional area of the pipeline, so that a small amount of water is discharged at an appropriate water pressure even when the valve is habitually opened 100%. Would have made it possible.

The current water supply system is generally configured to increase the discharge amount according to the open state of the valve handle. As shown in the graph of FIG. 1, the discharge amount is increased according to the open state of the valve handle. For example, with a water pressure of 2 kg / cm 2, the discharge amount increases from 10 l / min, 25% to 16 l / min, 50% to 22 l / min and 100% to 29 l / min at 15% open.

However, the amount needed by the user is sufficient at 10 L / min of 15% open in Graph A of FIG. However, the user habitually uses the valve handle in an open state of 50 to 100%, resulting in a large amount of water wasted. In order to prevent this, using a little open valve is difficult to practice at home, and moreover, it is almost impossible in public places due to lack of ownership. On the other hand, if the main valve on the pipeline to reduce the quantity of water to reduce the water pressure of all the lines becomes inconvenient to use.

Recently, the water valve has been designed to be opened by adjusting the handle of the water valve in multiple stages as a method for saving water at home or public places, but it is also necessary for the user to be aware of the operation method of the water valve. Since it was necessary to operate it by tilting, it is a situation that 100% of water saving effect is not exhibited.

On the other hand, in the prior art associated with the present invention, Japanese Patent Laid-Open No. 9-95985 connects three or more through-holes to the circumferential body, so that the through-holes are widened from each other toward the outlet side from the main body inflow surface. The idea of forming an angle of eccentricity is shown. However, the cylindrical main body described herein tends to have a significant drop in feeling such as the inflow surface and the outflow surface are flat, which reduces the discharge amount but causes water hammer.

The present invention has been devised to solve the above-mentioned conventional problems, and the present invention has a feeling of use before and after installation by maintaining the proper amount of water at the same water pressure without increasing the amount of discharge more than necessary even if the valve is installed in the water pipe to open 100%. It is to provide a water-saving kit that can be saved by making it possible to naturally restrain the unnecessary water without changing.

In order to achieve the above object, the present invention, in the water-saving kit mounted in the water pipe, to form a concave inclined surface to prevent the pinch around the inlet portion, is formed for water flow between the inlet and outlet The through hole is formed in a nozzle shape so that the inner diameter of the discharge part is smaller than the inner diameter of the inlet part, but the through hole is formed parallel to the axial direction of the water saving kit to prevent water pressure drop due to the nozzle effect. It provides a water-saving kit formed in a tapered shape that the diameter of the inlet side is smaller than the diameter of the discharge side so that it can be easily inserted into the water pipe of the.

Hereinafter, with reference to the accompanying drawings, preferred embodiments that do not limit the present invention will be described in detail.

Figure 2 is a perspective view of the water-saving kit according to the present invention, Figure 3 is a cross-sectional view taken along line A-A of Figure 2, Figures 4 to 6 shows the installation state of the present invention.

2 to 6, the water-saving kit 10 of the present invention is inside the water pipe, for example, a faucet of the water pipe and the basin as shown in Figs. The inside of the angle valve (1) installed between, that is, the flexible hose (2) connected to the faucet is fitted inside the flexible hose coupling hole (3) of the angle valve (1) is coupled to the end of the flexible hose (2) Installation is possible by tightening the nut 4, and in the case of the kitchen faucet, as shown in FIG. 6, the nut 6 is inserted into the outlet side of the adjustment arm 5 for coupling the faucet 8 to the water pipe. Installation is possible by tightening.

Water-saving kit 10 according to the present invention consists of a short cylindrical shape and a flange 12 is formed on the outside of the discharge portion 11, the diameter of the inlet portion 13 is larger than the diameter of the discharge portion 11 It is slightly tapered in overall shape, and a plurality of through holes 14 for passing water are formed between the inlet portion 13 and the discharge portion 11.

The flange 12 outside the discharge part 11 is for preventing the flow of the water-saving kit during assembly, and is attached to the edge of the flexible hose coupling hole 3 of the angle valve 1 and one end of the flexible hose 2. The nut 4 is installed in close contact between the packings 7 and 7 '.

The water-saving kit 10 is formed so that the diameter of the inlet part 13 is formed in a tapered shape as a whole smaller than the diameter of the discharge part 11 side, so that rust is attached to the inner wall of the tube by using the already installed and reduced tube diameter. It is to facilitate the insertion of the water-saving kit of the present invention into the water pipe or the angle valve.

The plurality of through holes 14 drilled between the inflow portion 13 and the discharge portion 11 are formed such that the inner diameter of the discharge portion 11 side is smaller than that of the inflow portion 13 side. The water flowing into the through hole 14 from the) side is discharged to the discharge part 11 side and pressurized by the reduction of the cross-sectional area of the through hole 14 to be sprayed toward the discharge part 11 to have a nozzle effect. The through hole 14 is formed parallel to the axial direction of the water saving kit 10 so that water injected into the discharge part 11 through the through hole 14 hits the inner wall of the flexible hose 2 to generate noise. To prevent it from happening.

When the water-saving kit 10 of the present invention is installed inside the water pipe, the cross-sectional area of the water pipe is reduced to the sum of the two cross-sectional areas of the through-holes 14, so the discharge amount is limited, and the size and number of the through-holes 14, through-holes ( According to conditions such as the diameter of the inlet 13 side and the diameter difference of the discharge 11 side of 14), it is possible to set and design a quantity suitable for the installation place.

In addition, the water-saving kit 10 of the present invention by forming the inclined surface 16 concave around the inlet portion 13 so that the dead zone (되는) where the flow of tap water is stagnant during the flow of tap water does not occur By preventing the buildup of water on the inlet (13) side to prevent clogging it was possible to use for a long time without being separated.

The water-saving kit of the present invention has excellent strength and corrosion resistance when manufactured with a metal alloy, and can reduce manufacturing cost when injection-molding with a resin. Also, when sintering is produced by adding an antimicrobial agent of special ingredient to a metal powder, It may have an antimicrobial effect on water contaminated during drainage.

After installing the water-saving kit according to the present invention, the discharge amount of water according to the opening ratio of the water valve is about 16% which is about 50% compared to the conventional case when the water valve is opened 100% as shown in FIG. It can be seen that the decrease to ~ 17ℓ / min, the user can use a sufficient amount of water without any inconvenience, and can effectively save the excessive waste of water.

As described above, the water-saving kit of the present invention is installed in the water pipe, so no additional equipment is required, and it does not complicate or mess the kitchen or bathroom piping. After unpacking, or after removing the faucet is inserted into the inside of the angle valve body or control arm and reassembled, it is possible to easily install the main valve without the number of all the lines due to the lock as in the prior art. In addition, the water-saving kit of the present invention is installed in the water pipe and when the water flows along the through-hole of the inlet side, the quantity is reduced to move to the discharge part, so the quantity is reduced by the cross-sectional area of the inlet through-hole, so unnecessary quantity is suppressed. The water-saving effect can be obtained, and since the through-hole has a nozzle shape, the amount of discharged water is reduced by the nozzle effect, but the water pressure is maintained as it is. In addition, the water-saving kit of the present invention can obtain semi-permanent water-saving effect by having sufficient strength and corrosion resistance by cutting the metal alloy, and can be produced at low cost in terms of corrosion resistance as well as corrosion resistance if the manufacturing of water-saving kit is made of resin. . In the case of manufacture by metal sintering, by adding a special ingredient to the metal powder can be produced water-saving kit that has the effect of antibacterial action.
