DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot and cold water mixing faucet, and more particularly, to a hot and cold water mixing faucet having a temperature control handle and a water discharging and stopping handle. More specifically, the present invention relates to a hot and cold water mixing faucet suitable as a deck type to be installed on a counter of a kitchen or a wash basin or a wash basin.

[0002]

2. Description of the Related Art A single-lever type hot / water mixing faucet is widely used as a hot / water mixing faucet installed in a kitchen, a basin counter, a basin (including a hand basin), and the like. This single-lever hot and cold water mixing faucet controls the water discharge and water discharge temperature (temperature control) with a single lever handle. The water discharge temperature is adjusted by moving the handle left and right, and the handle is moved up and down. By moving, water discharge and flow rate adjustment (flow regulation) are performed.

[0003] Another type of hot and cold water mixing faucet is a two-handle type in which a temperature control handle is provided at the left end of the faucet body and a water discharge / stop handle is provided at the right end. In this case, each handle is turned up and down.

[0004]

When an elderly person or a handicapped person operates the handle of a faucet, the elbow may be placed on the edge of the sink, and only the hand side may be moved to turn the handle.
In such a case, it is relatively easy to turn the handle in the left-right direction, but it is difficult to turn it in the up-down direction. For this reason,
The conventional single-lever hot water mixing faucet and the two-handle hot water mixing faucet are both difficult to operate for a user using such elbows.

An object of the present invention is to provide a hot and cold water mixing faucet which can be easily operated even with an elbow attached.

[0006]

A water mixing faucet according to the present invention is provided with a temperature control valve for adjusting a mixing ratio of hot water and a water discharging and stopping water for controlling water discharge, water stoppage and flow rate in a water faucet body. A temperature control handle for operating the water stop valve from the faucet body and a water stop handle for operating the water stop valve, the temperature control handle and the water stop handle The temperature control valve and the flow control valve are operated by turning only in the horizontal turning direction.

[0007] In such a hot and cold water mixing faucet, both the temperature control handle and the water discharge stop handle are operated to rotate only in the horizontal direction, so that the temperature control operation and the water discharge stop operation can be performed even when the user keeps the elbow attached. Easy to do.

In the present invention, when the water discharge pipe is projected from the faucet body, both the temperature control handle and the water discharge stop handle may be arranged above the water discharge pipe. In this case, the water discharge pipe is less likely to be in the way during operation. In this case, it is preferable to dispose the water discharge handle above the temperature control handle because the water discharge handle is used more frequently than the temperature control handle. For the same reason, it is preferable to make the water discharge / stop handle longer than the temperature control handle. Also,
When the water discharge pipe projects from the faucet body, the water discharge stop handle may be disposed above the water discharge pipe, and the temperature control handle may be disposed below the water discharge pipe.
