Chlorine generator

Abstract

A chlorine generator includes a main water channel for connecting to a pool and a subsidiary water channel connected between two points on the main water channel. A feed valve, a brine tank, a pump and an electrolytic tank are located on the subsidiary water channel. Salt is added into the brine tank and dissolved in water drawn in from the main water channel, and the high concentration saline solution is pumped from the brine tank into the electrolytic tank where chlorine is generated from the saline. The chlorinated solution from the electrolytic tank is then mixed with the water in the main water channel. A stirring device is provided at the bottom of the brine tank to stir the water therein to facilitate the generation of high concentration saline solution. Salt is electrolyzed without being dissolved into the swimming pool directly, thereby reducing harmful effects to swimmers.

1 . A chlorine generator, comprising:
 a brine tank;   a main water channel;   a subsidiary water channel connected between an upstream point and a downstream point on the main water channel;   a stirring device located at the bottom side of the brine tank; and   an electrolytic tank for generating chlorine from a saline solution by an electrolysis reaction,   wherein the brine tank, the stirring device and the electrolytic tank are located on the subsidiary water channel, whereby chlorinated water from the electrolytic tank enters the main water channel.   
     
     
         2 . The chlorine generator as claimed in  claim 1 , further comprising a feed valve located between the main water channel and the brine tank on the subsidiary water channel for controlling water flow from the main water channel to the brine tank. 
     
     
         3 . The chlorine generator as claimed in  claim 2 , wherein the feed valve is a press-down valve, a rotary valve or a push-pull valve. 
     
     
         4 . The chlorine generator as claimed in  claim 1 , wherein the stirring device includes stirring blades driven by a motor or by water power. 
     
     
         5 . The chlorine generator as claimed in  claim 1 , further comprising a pump located on the subsidiary water channel between the stirring device and the electrolytic tank for pumping saline from the brine tank into the electrolytic tank, wherein the stirring device and the pump are either mounted on a common shaft driven by a motor or are driven by separate motors. 
     
     
         6 . The chlorine generator as claimed in  claim 1 , wherein the electrolytic tank includes a plurality of vertical titanium plates for carrying out the electrolysis reaction, and wherein water flows upward inside the electrolytic tank. 
     
     
         7 . The chlorine generator as claimed in  claim 1 , further including a flow valve in the main water channel for turning off the electrolytic tank when the water flow in the main water channel is below a predetermined value. 
     
     
         8 . The chlorine generator as claimed in  claim 1 , wherein the brine tank includes a dismountable upper drum and a lower drum, where the upper drum is capable of fitting in the inside of the lower drum when turned over for packaging. 
     
     
         9 . The chlorine generator as claimed in  claim 1 , further comprising a filter screen or a water permeable sack inside the brine tank. 
     
     
         10 . The chlorine generator as claimed in  claim 1 , further comprising a salt port cover for covering a salt port of the brine tank, the salt port cover capable of functioning as a measuring cup. 
     
     
         11 . The chlorine generator as claimed in  claim 1 , further comprising a water level detector inside the brine tank for turning off the electrolytic tank when the water level inside the brine tank is below a predetermined value.
