System controlling shower water flow

Abstract

The invented system controls hot and cold water flows to a conventional shower. It includes a soap dish; dish cover; fitting with interconnected lower and upper chambers having a through flow capable of interrupting by a ball, the lower chamber downwardly connected to the shower; a cross-shaped valve having a shaft with a fixed pusher lowered by said dish cover when opened by the user during lathering, thereby shutting the water by the ball, and said pusher lifted when the dish cover closed, thereby opening the water; a pressure balance mixer connected to the upper chamber, comprising left and right chambers, conical connectors, frame, balancer, divider, left and right balls, stabilizing the outlet mixed water temperature when the hot or cold water pressure fluctuates, keeping previous regulation settings of the hot and cold taps allowed to be constantly opened, while the cross-shaped valve shuts and opens the outlet mixed flow.

1 . A system controlling a cold water flow inlet from the conventional cold water supply system and a hot water flow inlet from the conventional hot water supply system both outlet to a shower, or tub, or sink device, said controlling system comprising: 
 a mixing means for combining of said cold and hot water flows into one mixed flow;    a soap holding means;    a soap covering means capable to be actuated by a user preferably during the lathering process;    a transmission means for receiving said mixed water flow, and further directing it to the shower, tub, or sink device;    an interrupting valve means capable to close and open said transmission means when being actuated by said soap covering means.    
   
   
       2 . The system according to  claim 1 , wherein 
 said transmission means comprising an upper chamber connected to said mixing means, a lower chamber connected to said shower, or tub, or sink device, a round hole connecting the upper and lower chambers;    said interrupting valve means comprising a cross-shaped valve disposed within said transmission means; said cross-shaped valve including: 
 a rotatable elongated valve shaft supported by said transmission means, said shaft having a rectangular cross-section at its ends for attachment to said soap covering means, said shaft having a segmental cutoff substantially made at the middle of the shaft, said shaft having a threaded hole drilled substantially at the middle of the cutoff perpendicularly to the central longitudinal axis of said shaft;  
 a pusher having a flag-like profile, made as a whole of a head portion with the working profile shaped as part of an ellipse curve and a threaded leg portion capable to be screwed into said threaded central hole;  
 a central ball capable to close said round hole by freely rolling down into the round hole, and capable to open the round hole by rolling out of said round hole while being pushed up by said pusher when the pusher being actuated by the soap covering means.  
   
   
   
       3 . The system according to  claim 1 , wherein said mixing means further comprising a balancing means capable to regulate said cold and hot water flows so that when the pressure of at least one of the flows increasing against the other, thereby changing the temperature of the mixed flow, the flow with increased pressure being reduced by said balancing means resulting in the mixed flow re-acquiring substantially the same temperature it had prior to said increasing of pressure of one of the water flows; said balancing means supported by said mixing means.  
   
   
       4 . The system according to  claim 3 , wherein 
 said mixing means comprising a hot-cold water horizontal tubular mixer with a pressure balancer, said mixer including a housing with a central part downwardly connected to said transmission means, a left chamber and a right chamber attached to the central part with their corresponding ends, said mixer including two conical connectors narrowing respectively to the left and the right ends of the mixer, said connectors attached by their wider ends to the respective ends of the left and right chambers, said connectors attached by their narrower ends to hot and cold water conventional hand-regulated valves correspondingly connected to the hot and cold water supply systems;    said balancing means comprising a hot-cold water pressure balance valve including: 
 a frame mounted inside the central part, said frame having a bottom with an opening, and said frame having two sidewalls each with a groove on its top;  
 a pendulum balancer having a bottom performed as a portion of an annular shape, a window at the center of the bottom, a front wall and a back wall both of a sector-like shape, and two horizontal tongues at the tops of the front and back walls; said balancer suspended on said frame by placing its tongues within the grooves of the frame;  
 a divider having two leaned sides and upper wings horizontally folded out and supported by the top portions of the sidewalls of said frame;  
 a left ball and a right ball disposed respectively within the left and the right chambers of the housing and capable to freely roll along the chambers and the conical connectors until stopped by the narrowing body of connector wherein shutting the water flow in the connector; said left and right balls capable to move said balancer respectively to the right or to the left whenever a pressure difference between the cold and hot water existing and providing the movement of said balancer toward the chamber with the lower pressure, wherein the overlapping areas of the frame's opening and the balancer's window to the left and the right sides of the center of said divider changing, thereby reducing the water flow with the increased pressure and stabilizing the temperature of the mixed water flow.
