Description

The present invention mainly relates to a branch faucet in which a new spout can be attached to and detached from a pipe extending from the faucet to the spout.

There are many types of existing branch faucets, and they can be switched to two systems, such as those that supply water or hot water to a water purifier or dishwasher separately from the faucet, or those that supply water from the faucet or water from the shower. There is a branch faucet to use. It was installed by choosing a branch faucet depending on the purpose of use. There is no branch faucet that can be easily attached when equipment is in use and removed when not in use. Instead, it is always connected and has a cock that shuts off the water when you want to prevent water from flowing into the equipment. branch faucets are common.

I cannot find any prior art document information that should be described for devices, instruments, etc. that are similar or related to the present invention.

However, installing a new spout requires construction and cannot be easily increased. If there is no faucet in the place where you want to put the washing machine, it is convenient to draw water with a hose, but many spouts and faucets installed indoors do not have a structure to attach a new hose. In addition, if the shower hose or the like is attached to the bathroom vanity from the beginning, it may take up space and become an obstacle. For existing branch faucets, you can switch the spout by twisting the branch lever or cock, and for wall-mounted mixer taps for bathrooms, turning the switching handle up opens the water outlet on the shower side, and turning it down on the spout side opens the water outlet. It is a switching type, etc., and any type can be used only from the installed spout by performing the operation to switch the branch of the two systems. Therefore, it is not possible to easily attach or detach an object installed on the branch faucet. In addition, there are no stand-mounted single-lever type hot and cold water mixing faucets that can branch and switch the spout to two systems, and faucets with a branch outlet can branch water or hot water depending on whether the water supply pipe is on the hot or cold side. It is a branch faucet that can be connected, and there is no one that branches the mixed water.

The present invention, as shown in the side view before connection in FIG. 3 and the side view after connection in FIG. It is a structure for switching the water outflow channel by connecting a new one when you want to use more water outlets in the system. The structure of this water discharge pipe branch is composed of a T-shaped branch pipe 1, an insertion branch pipe 2, a compression coil spring 4, a joint pipe 6, a switching release button 8, and an insertion connection pipe 7. As a mechanism for branching, an insertion branch pipe equipped with a compression coil spring is inserted from the insertion opening 1a of the T-shaped branch pipe. As shown in the image diagram of FIG. 30, the insertion branch pipe stays at a fixed position unless a strong force is applied between the compression coil spring support 1c of the T-shaped branch pipe and the insertion branch pipe stopper 5 due to the repulsive action of the spring. The joint pipe is fitted into the T-shaped branch pipe insertion port in that state and fixed. At that time, it is necessary to fit the joint pipe into the T-shaped branch pipe while pushing the insertion branch pipe with a finger until the anti-rotation guide 2a2b of the insertion branch pipe does not hit the inside of the joint pipe. Adjust so that the anti-rotation guide 2a2b of the insertion branch pipe fits into the anti-rotation rail 6a6b of the pipe. From the other side of the joint pipe, the insertion branch pipe insertion part 7a of the insertion connection pipe is inserted into the insertion branch pipe, and then further pushed into the joint pipe until it is fixed by the fixing claw B stopper 7b. As shown in the image of FIG. 21, the plug-in branch pipe is pushed up to the plug-in branch pipe bearing 1b where the T-shaped branch pipe hits, so that the water flow can be switched at right angles, and the hose connected to the plug-in connection pipe You will be able to spout water from the shower head. When removing the shower head or the like, pressing the switch release button removes the fixing claw B stopper of the insertion connection pipe, pushes it out by the force of the compression coil spring, and at the same time the water outflow path returns to the original water supply path. Connect the plug-in connection pipe to the water inflow channel side of the shower head that you want to connect mainly to the water discharge pipe, and insert the plug-in connection pipe into the plug-in switching branch faucet until it stops with the fixed claw B stopper. When the water outflow channel is switched and the switch release button is pressed, the fixing claw B stopper of the insertion connection pipe is released, the insertion branch pipe is pushed out by the force of the compression coil spring, and at the same time the water outflow channel can be removed. Returning to the original water supply path, the shower head can be easily attached to and detached from the discharge pipe. However, if the insertion branch pipe rotates, it will not function properly, so the branch water receiving port 2e must always face the water inflow channel side. For this reason, the rotation prevention guide 2a2b of the insertion branch pipe is fitted into the rotation prevention rail 6a6b of the joint pipe, and the rotation prevention guide 7c7d of the insertion connection pipe is fitted into the rotation prevention rail 2c2d of the insertion branch pipe. The tube and the plug-in tube are no longer rotated. Therefore, the fixing claw B stopper of the plug-in connection pipe is accurately fitted into the plug-in pipe fixing hole B6d of the joint pipe.

As described above, the present invention is a faucet for bathroom vanities, kitchens, and the like, where the plug-in switchable branch faucet of the present invention is installed in a pipe that spouts water from a cartridge for a single-lever type hot and cold water mixing faucet. When a plug-in connection pipe such as a shower head with a plug-in connection pipe connected to the inflow channel side is inserted into the plug-in switching branch faucet to a position where it is stopped by a fixed claw B stopper, the water outflow channel is switched simultaneously with the connection. When the switching release button is pressed, the fixing claw B stopper of the insertion connection pipe is released, and the insertion branch pipe is pushed out by the force of the compression coil spring, and the insertion connection pipe can be removed. . Thus, a new spout can be easily attached and detached. In addition, most bathroom vanities are equipped with a single-lever type hot and cold water mixing faucet called a one-hole type with a table (with a counter) or a separate washbasin type with a table (with a counter). According to the present invention, it is possible to install a single-lever type hot and cold water mixing faucet with a built-in spout switching branch that can be switched to two systems on the bathroom vanity, and new possibilities can be added to the utilization of the bathroom vanity. .
