Can be easily adjusted.

According to the present invention, it is characterized in that the discharge pipe 20 for finally discharging water to the discharge port 16 of the faucet body 10 is rotatably fastened 360 degrees in the forward and backward directions.

To this end, as shown in FIG. 2, a hollow rotation support rod 20-1 is integrally protruded from the rear end of the discharge pipe 20, and the rear end of the discharge pipe 20 and the rotation support rod 20-1 are integrally formed. 1) A locking groove 20-2 is formed at the boundary between the two, and a seal is formed between the rotation support rod 20-1 and the second male screw portion 18 formed in the discharge port 16 of the faucet body 10 ( 22) is provided and coupled by the second rotation guide nut 24.

At this time, the second rotation guide nut 24 has a structure in which a second stopper end 24-1 bent inwardly is integrally formed at the front end thereof and a female screw 24-2 is formed on the inner diameter of the rear end. are provided

Preferably, in a state where the second stopper end 24-1 of the second rotation guide nut 24 is caught in the locking groove 20-2, the front end of the rotation support rod 20-1 is connected to the discharge pipe ( 20) can be integrated by a method such as thermal fusion or welding.

Thus, the second stopper end 24-1 of the second rotation guide nut 24 can be inserted into the locking groove 20-2 to prevent separation, and the second stopper end 24 -1) becomes a 360 degree rotatable state in the locking groove 20-2.

In addition, the second male screw portion 18 formed in the discharge port 16 of the faucet body portion 10 with the female screw 24-2 of the second rotation guide nut 24 interposed therebetween the seal 22 By screwing with, the assembly of the discharge pipe 20 to the faucet body 10 is completed.

As described above, in a state in which the discharge pipe 20 is assembled to the discharge port 16 of the faucet body 10, when the second rotation guide nut 24 is rotated in one direction (tightening direction), FIG. As shown, the rotation support rod 20-1 is tightly fixed to the discharge port 16 while compressing the seal 22, so that the discharge pipe 20 having the rotation support rod 20-1 is fixed so as not to move become a state

On the other hand, when the second rotation guide nut 24 is slightly rotated in the other direction (unwinding direction), as shown in FIG. 16), the rotation support bar 20-1 becomes rotatable by 360 degrees along the front-back direction, and the discharge pipe 20 having the rotation support bar 20-1 is also along the front-back direction. It becomes possible to rotate 360 degrees.

Therefore, as shown in FIG. 5, the user can hold the discharge pipe 20 and easily rotate it to a desired position (a position for supplying water to the washing machine) along the forward and backward directions.

In this way, when trying to connect the discharge pipe 20 of the faucet and the hose connector of the washing machine, the faucet body 10 connected to the water supply pipe is rotated 360 degrees in the vertical direction or connected to the faucet body 10. By rotating the discharge pipe 20 forward and backward by 360 degrees, the discharge arrangement direction of the discharge pipe 20 can be easily adjusted toward the hose connector of the washing machine, and the discharge pipe of the faucet and the hose connector of the washing machine can be easily adjusted in a narrow space. It is possible to provide convenience in that the hose connection between the tubes can be easily made.

Meanwhile, an antifouling coating layer made of an antifouling coating composition may be applied to the faucet body 10 to effectively prevent adhesion and removal of contaminants.

The antifouling coating composition contains tetraethyl ammonium hydroxide and methyl ethyl ketone (MEK) in a molar ratio of 1:0.01 to 1:2, and the total content of tetraethyl ammonium hydroxide and methyl ethyl ketone is the total aqueous solution It is 1 to 10% by weight relative to.

The molar ratio of tetraethyl ammonium hydroxide and methyl ethyl ketone is preferably 1:0.01 to 1:2. If the molar ratio is out of the above range, the coating property of the faucet body 10 is reduced or the surface moisture after application is reduced. There is a problem in that the coating film is removed due to increased adsorption.

The tetraethyl ammonium hydroxide and methyl ethyl ketone are preferably 1 to 10% by weight in the total aqueous solution of the composition. If the content is less than 1% by weight, there is a problem in that the coating property of the faucet body 10 is lowered, and 10% by weight If it exceeds, crystallization is likely to occur due to an increase in the thickness of the coating film.

On the other hand, as a method of applying the antifouling coating composition to the faucet body 10, it is preferable to apply it by a spray method. In addition, the final coating film thickness of the faucet body 10 is preferably 700 to 2500 Å, more preferably 900 to 2000 Å. If the thickness of the coating film is less than 700 Å, there is a problem of deterioration in the case of high-temperature heat treatment, and if it exceeds 2500 Å, there is a disadvantage in that crystallization of the coated surface is easy to occur.

In addition, this antifouling coating composition can be prepared by adding 0.1 mol of tetraethyl ammonium hydroxide and 0.05 mol of methyl ethyl ketone to 1000 ml of distilled water, followed by stirring.

The reason why the ratio of the constituent components and the thickness of the coating film were numerically limited as described above was that the present inventors showed the optimal antifouling coating effect at the ratio as a result of analyzing the test results while repeating several failures.

In addition, the seal 22 may be made of a rubber material, and the raw material content ratio of the seal 22 is 58% by weight of rubber, 6% by weight of diphenylguanidine, 6% by weight of thiocarbanilide, and 3% by weight of zinc laurate. , 19% by weight of carbon black, 4% by weight of 3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE), and 4% by weight of precipitated sulfur were mixed.

Diphenylguanidine and thiocarbanilide are added to improve acceleration, etc., zinc claurate is added to act as a softener, and carbon black is added to increase or improve wear resistance, thermal conductivity, and the like.

3C (N-PHENYL-N'-ISOPROPYL-P-PHENYLENEDIAMINE) is added as an antioxidant, and a precipitate is added to act as an accelerator.

Therefore, according to the present invention, elasticity, toughness, and rigidity of the seal 22 are increased, so durability is improved, and thus the life of the seal 22 is increased.

The tensile strength of the rubber material is formed at 155Kg/㎠.

The reason for limiting the components and components of the rubber material and limiting the numerical values of the mixing ratio is that, as a result of the inventor's analysis through test results while repeating several failures, the optimal effect in the constituent components and numerically limited ratios showed up

In addition, when the front end of the rotation support rod 20-1 is integrated with the rear end of the discharge pipe 20 by thermal welding, an adhesion enhancer may be applied between them to increase bonding strength.

The adhesion enhancer may include 60 parts by weight of water, 17 parts by weight of 2-heptadecylimidizol, 15 parts by weight of N-acyl taurate, 7 parts by weight of ammonium persulfate, and 1 part by weight of sodium acetate.

2-Heptadecylimidizol is added to improve adhesion and hardening acceleration, N-acyltaurinate acts as a surfactant, ammonium persulfate acts as a catalyst, and sodium acetate acts as a buffer. .

The reason for limiting the constituent materials and components and limiting the numerical values of the mixing ratios as described above is that, as a result of the present inventors' analysis through test results while repeating several failures, the optimal effect in the constituent components and numerically limited ratios was obtained. showed up
