<p>PURPOSE:To enable to supply hot water in a short time and to agitate bathing water by a structure wherein a water flow rate control nozzle is provided at a bubble generating part by venturi effect arranged in a hot water supply passage. CONSTITUTION:A bubble generating part 7, which sucks air by venturi effect due to the velocity of hot water stream, is arranged in a hot water supply passage connecting a water heater 2 with a bathtub 4. A water flow rate control nozzle 8 is arranged in the tip pipe of a service hot water outlet pipe 6 in the bubble generating part 7 so as to be controlled by a remote controller 9. Due to the structure as mentioned-above, when automatic feeding of hot water to the bathtub is intended, the short time automatic hot water feeding is made possible, because a large amount of water can feed. In addition, when additional burning is wanted, the raising of the water level in the bathtub can be reduced by throttling the amount of water and further the agitation of bathing water fitted for additional burning is also made possible.</p> |
