When discharging the residual water relates to a freeze protection tap water provided with an auxiliary discharge pipe that can be used as the air inlet pipe.

Although many water taps for freeze prevention of water pipes have been devised in the past, in most cases, when only one water pipe is installed and attached to a washing machine, tap water cannot be supplied where additional tap water should be used. In order to discharge the residual water by introducing into the drainage valve, a complicated drainage valve and a locking device are adopted, which makes it difficult to use, and it is difficult to repair or replace parts due to failure or wear.

The applicant of the present invention proposes a drain valve for water pipe freeze prevention, which compensates the above-mentioned drawbacks and makes the structure of the valve extremely simple and easy to use. It was announced as Utility Model Publication No. 94-292 has already been registered, but the pre-registered water pipe freeze-drain drain valve is because the water inside the water pipe is to be drawn out only when the air flows from the faucet, lock the faucet or When the water supply hose attached to the washing machine is connected to the faucet, the drain valve of the faucet or the washing machine is shut off manually or automatically, so that no air flows through the outlet of the faucet so that the water is discharged easily through the drain passage of the drain valve. Problem and the drainage passage is the central part of the valve support rod. Because there were shortcomings finely pierced the air inlet and drainage is difficult being smoothly conducted simultaneously. To improve this, the applicant of the present invention uses a water head head device of a water pipe freeze prevention valve, which prevents freezing of water pipes by discharging the residual water filled in the water discharge pipes, Utility Model Registration Application Nos. 93-15708 and 93-27333. As proposed above, the above designs also have a structure in which a spun head and a plurality of packing rings are formed in which a vantilizing groove is formed on an outer circumferential surface in order to introduce external air into the faucet, and the structure is complicated and its function is complicated. Since the site must be precisely processed, there are disadvantages such as an increase in manufacturing cost.

The present invention is convenient to use because it can discharge the tap water to the auxiliary outlet pipe as well as the outlet pipe by installing the auxiliary outlet pipe at a predetermined angle away from the outlet pipe to solve the above disadvantages, When draining residual water to prevent freezing of water pipes, the auxiliary water outlet pipe is used as an air inlet so that a separate air inlet pipe or an air inlet device is not required, and the freeze wave prevention device is provided with an auxiliary water outlet pipe that can simplify the valve structure. The purpose is to provide a water war.

In order to achieve the above object, the freeze-proof water tap of the present invention has a water pipe coupled to a water pipe, in which upper and lower through holes and a valve installation pipe communicate with each other, and a first inner plate having a first hole is formed. The other end of the pipe is connected to the faucet with a water outlet pipe is formed, the first spun rod is inserted into the water pipe along the longitudinal direction and one end of the first spun rod in close contact with the first valve seat A first valve disc is provided to block water flow, and a first spun head screwed with a faucet is attached to the other end of the first spun rod, and the faucet is provided with an auxiliary discharge pipe at a predetermined angle. A second inner plate is formed in the faucet inner wall having a second through hole which communicates the water outlet pipe and the auxiliary water outlet pipe with each other, the second valve device for opening and closing the second hole at one end. A second spun rod with a cradle is attached to the second spun head screwed to the faucet and attached to the other end of the second spun head in a known manner by means of an adjustment knob. The second valve disc at the end of the second spun rod ends by opening and closing the second spun rod through the rotation operation of the adjustment knob to open and close the second through hole.
