Patent ID: 7861742

Claim:
A cartridge of a water supply valve, comprising: water supply and discharge means ( 1 ) provided with cold and hot water supply holes ( 1 a and 1 b ) to separately supply cold and hot water into the cartridge and a water discharge hole ( 1 c ) to discharge a mix of the cold and hot water from the cartridge; a control unit ( 15 ) to open or close the cold and hot water supply holes ( 1 a and 1 b ) of the water supply and discharge means ( 1 ); and a housing ( 2 ) assembled at a first end thereof with an end of the water supply and discharge means ( 1 ) to define a chamber therein and receiving elements of the cartridge in the chamber to protect the elements, wherein the cartridge further comprises valve control means ( 11 ) which includes: a flow rate control knob ( 12 ) coupled by a hinge to a second end of the housing ( 2 ), which is assembled with the water supply and discharge means ( 1 ), so that the flow rate control knob ( 12 ) is moved back and forth in a first direction and within a pre-determined angular movement range and actuates a control lever ( 14 ), an end of which is coupled to the control unit ( 15 ), thus causing the control unit ( 15 ) to open or close the cold and hot water supply holes ( 1 a and 1 b ) of the water supply and discharge means ( 1 ); and a temperature control knob ( 13 ) slidably and movably coupled on the flow rate control knob ( 12 ) such that the temperature control knob ( 13 ) linearly moves back and forth in a second direction perpendicular to the first movement direction of the flow rate control knob ( 12 ) and within a predetermined linear movement range without causing interference with operation of the flow rate control knob ( 12 ), and actuates the control lever ( 14 ), which is coupled to the control unit ( 15 ), thus causing the control unit ( 15 ) to control the opening ratios of the cold and hot water supply holes ( 1 a and 1 b ) of the water supply and discharge means ( 1 ).
