報の第３図（本願図面の第５図）のものがある。 Conventionally, the connection pipe used in cold regions that connects the hot water mixer tap and the water supply pipe is equipped with a water drain device to prevent connection, as shown in Figure 3 of the earlier application Publication No. 1983-27718 (the drawing of the present application). (Figure 5).

る。 To briefly explain the above FIG.
1 is provided with a valve port 42 and a drain hole 43 diagonally downward, and a drain chamber 44 and a drain chamber 4 are provided at the extension lower part of the drain hole 43.
A valve portion 46 is provided with a threaded port 45 that communicates with the drain hole 43, and the threaded port 45 closes the drain hole 43 except when draining water.
A drain plug 47 is screwed in and has a drain hole 43a that communicates with the drain chamber 44 and drains residual water in the hot water and water mixing tap and flow path 41a to the outside when draining water.

にするなどの不都合が後を絶たなかつた。 In the case of the above, after opening the drain valve and draining water, leave your hands that have leaked into the residual water during the period (about 2 to 3 minutes) until the draining is finished to avoid the cold. Waiting during the increasing night hours was extremely painful work. In particular, this work is often done by children, so they often end up closing the drain valve at an appropriate time, which can result in residual water freezing the faucets or connecting pipes, or closing the drain valve. As a result of forgetting to do so, there was no end to the inconveniences, such as flooding indoors when the water was turned on the next morning.

ようにしたものである。 The basic structure of this device is to have a valve mechanism on the top of the main body that freely supplies hot water at an appropriate temperature by operating a pair of ceramic plate valves via a single lever. In the middle of the water flow path of the hot water mixer faucet body, which has a hot water flow path and a water flow path, a valve port that is opened and closed with a check valve having an actuated head and a drainage chamber that communicates through the valve port is provided. A push rod having an operating head is supported through a sleeve nut in a screw hole provided in the drainage chamber, and the push rod maintains the correspondence between the packing wound around the circumferential surface and the inner circumferential surface of the through hole of the sleeve nut using dynamic friction. By interposing the push rod in a slidable manner, when the operating head of the push rod acts on the affected head of the check valve to perform drainage to prevent freezing, the push rod operates in one movement, and when water flows through the water flow path, the push rod operates in one motion. The push rod is designed to gradually return to the standby position due to the water pressure applied to the working head when water is flowing through the water flow path received by the working head.

了する。 Now, in order to perform freezing prevention drainage, the main valve of the water pipe has been shut off and the drainage mechanism 21 has been changed to the water stop valve shown in Fig. 1, and then we will explain how to perform freezing prevention drainage. When the push rod 14 is pushed in the direction of arrow F, the push rod 14 is pushed all at once to the position shown in FIG. Moving. In this case, since the operating head 11 of the push rod 14 moves together, the operating head 11 pushes up the waiting check valve 18 while engaging with the operated head 19 on the lower surface of the check valve 18 in the advancing direction. Due to this operation, the check valve 18 integrated with the operated head 19 is lifted and the valve port 5 is opened, so that the remaining water in the flow path 3 is discharged to the water pipe through the reverse route when water is passed. At the same time, since the normal drainage hole provided in the main valve is opened at the same time as the main valve is closed, this remaining water directly flows out through the drain hole. If the pressing rod 14 is left in the state of being pushed inside the through hole 10, drainage will be completed over time.

るものとする。 In order to use the water supply that has been prevented from freezing by the above-mentioned drainage the next morning, open the main valve and let the water flow as usual, and the water flowing through the water flow path 3 will flow into the drainage chamber 7 in Figure 3 A. The water pressure during reaching the drain chamber 7 and passing through the drainage chamber 7 is applied to the push rod 14 and the working head 11, and this water pressure overcomes the frictional force between the packing 13 of the push rod 14 and the inner wall surface of the through hole 10 of the sleeve nut 9. The push rod 14 is gradually pushed back in the opposite direction of the arrow F and automatically returns to the starting position shown in FIG. 1, and the above operation is repeated to perform anti-freeze drainage. Note that, at the same time as draining water from the water flow path 3, water is also drained from the discharge pipe 35 using the drain plug 50. It is also assumed that the drainage mechanisms 21 and 21a of the other embodiments operate in the same manner as described above.
