<p>The present invention relates to a water control valve cartridge, which includes a single control knob that is capable of controlling the flow rate and the temperature of water, the control knob being manipulated within a predetermined planar area and controlling the flow rate or the temperature of water exclusively, or controlling the flow rate and temperature of the water at the same time, the control knob also reducing the number of elements of the cartridge and simplifying the combined construction of the cartridge, and improving the construction for manipulation of the control lever. The water control valve cartridge includes a water inlet and discharge unit for supplying and discharging water into and from the valve cartridge, the water inlet and discharge unit comprising cold and hot water inlet holes respectively connected to cold and hot water pipes, and a water discharge hole; an opening ratio control unit for controlling opening ratios of the cold and hot water inlet holes of the water inlet and discharge unit; a control lever for controlling forward, backward, leftward and rightward movement of the opening ratio control unit through a joystick motion; a valve control unit comprising a control knob that moves in a plane and actuates the control lever; and a housing for restricting the forward, backward, left-ward and rightward movement of the opening ratio control unit while supporting the control lever that executes the joystick motion. In the operation of the water control valve cartridge, the control knob is manipulated forwards or backwards to control the flow rate of the water, and is manipulated leftwards and rightwards to control the temperature of the water. Thus, the motion of the control knob when controlling the flow rate of the water does not interfere with the motion of the control knob when controlling the temperature of the water. Therefore, the present invention prevents a change in the temperature of the water when the flow rate of the water is controlled, and prevents a change in the flow rate of water when the temperature of the water is controlled. Further, the control knob can be finely manipulated, thus preventing undesired consumption of an excessive quantity of water and easily maintaining the water at a desired temperature.</p> |
