IPC: H05B47/10
Filed: 1993-12-29
Abstract: PURPOSE: To prevent the temp. rise of the water stagnating in a water purifying device while maintaining the sterilization function thereof when the water does not flow therein.  
     CONSTITUTION: A control circuit 20 is disposed in order to decrease the electric current to a UV light emitting tube 16 when the water does not flow in the water purifying device. The control circuit is provided with an RC changeover circuit 22 which is selectively parallel connected with the light emitting tube. As a result, positive impedance is impressed in parallel with negative impedance of the light emitting tube. The control circuit of another embodiment is provided with the impedance to be series connected to a stabilizing circuit 14 for the light emitting tube. In either embodiment, the impedance circuit is driven in response with a water flow detecting switch 28. As a result, while the water flows to the water purifying device, the impedance is removed and the max. electric current is supplied to the light emitting tube and UV luminance is increased. When, no the other hand, the water does not flow thereto, the impedance is so applied as to decrease the electric current to the light emitting tube.
