HOT AND COLD WATER SUPPLY SYSTEM THAT CAN UTILIZE RESIDUAL WATER

摘要

According to the present invention, a hot and cold water supply system supplies residual water stored in a tank for residual water to a low tank of a toilet bowl in order to have an advantage of eliminating wasting of water since the residual water is not wasted. Moreover, the tank for residual water is installed inside a cabinet arranged above the low tank of a toilet bowl to enable an easy installation and an easy additional installation to existing facilities and to reduce the costs without a large scale construction to bury the tank for residual water in a wall or a floor of a bathroom. Moreover, the residual water is smoothly supplied since the residual water is supplied from the tank for residual water to the low tank of a toilet bowl in the gravity direction.
