Description

Hot water shut-off device and a faucet that automatically shuts off hot water}

The present invention relates to a hot water shutoff device and a faucet in which hot water is automatically shut off using the same. More specifically, when the faucet user lowers the faucet lever after use, the lever automatically moves to the cold water and the tap water is locked, thereby preventing unexpected and sudden hot water discharge and unnecessary boiler operation. Is about a faucet that is blocked.

A faucet is a device that allows or blocks cold and hot tap water, and the faucet generally includes a main body part 10 that is the center of the faucet, a lever part 20 for turning on or locking the tap water, a discharge part 30 for discharging tap water, and a faucet. It includes a fixing part 40 fixed to a wall surface, a sink, a sink, and the like.

The lever part 20 generally includes a lever body 21 operably coupled to the main body and a lever 22 used to turn on or lock tap water, and the discharge part 30 discharges the tap water through It includes a secondary body 31 and a discharge port 32 that serves as an outlet from which tap water comes out.

In a general faucet, the amount of cold water and hot water supplied to the cold water pipe and the hot water pipe, respectively, is controlled by a lever. When the lever is raised, tap water comes out, and when it is lowered, it is submerged.

And in general, hot water comes out when the lever is rotated to the left, and cold water comes out when the lever is rotated to the right (although there is a faucet that controls hot and cold water in the opposite direction).

The average user who uses tap water tends to involuntarily raise it up vertically without rotating the lever locked by all users when he/she wants to use it. That is, when all users place the lever toward hot water, hot water is often introduced, and when all users place the lever toward cold water, cold water is often introduced.

If all users put the lever on the hot water side, if the current user unknowingly raises the lever, the current user may be surprised by the sudden hot water discharge, or in severe cases, the current user may be burned. There was a problem that the boiler was operated unnecessarily because the lever was placed on the hot water side when not in use.

Moreover, in the case of infants, the elderly, and the disabled who are unable to smoothly control the hot and cold water of tap water, there is a problem that the probability of getting burned due to the sudden discharge of hot water increases.

In order to solve this problem, a technology for installing a device that can return the lever to the cold water inside the faucet has been developed, but the structure of the faucet becomes complicated, and the faucet manufacturing cost increases rapidly. It cannot be used, and there is a problem that the faucet itself needs to be replaced in order to apply the return device.

In addition, a technology to install a blocking bar to block the rotation of the lever toward the hot water has been developed, but the structure of the device is also complicated, so manufacturing cost has increased, and the use of hot water is limited in normal times, so the blocking bar must be lowered to use hot water. There was a hassle.

Therefore, production is simple and production cost is low. When hot water is used, hot water can be conveniently used, and when water is not used, the lever is always located on the cold water side to prevent safety accidents and to save energy. There was a need to develop a hot water shut-off device that anyone could easily and conveniently install on the faucet installed in the house and a faucet that cuts off hot water.
