Title: Hot water supplier
Inventor: MIYOSHI MASARU
IPC: F24H1/00
Filed: 1991-12-10
Abstract: PURPOSE:To improve convenience with easy hot water supply into a bath tank in a hot water supplier by automatically constricting the amount of water before a set water amount is attained and informing users through a buzzer of that fact. CONSTITUTION:A hot water supplier comprises a water passage including a water amount sensor 1, a heat exchanger 4, and a water amount proportional valve 23, and a gas passage including a parent solenoid valve 9, a proportional control valve 8, and a burner 6, and further a controller 25. When the accumulated water amount of an effluent hot water amount calculator 22 and a previous water amount before reaching a set water amount of a water amount adjusting knob 20 are coincident with each other during hot water being supplied into a bath tank, a buzzer 21 is actuated to inform users of a fact that the bath tank 13 is just before it is filled with water. Further, a hot water supply suppression indicator 24 issues an instruction signal to control the water amount proportional valve 23 and hereby restrict the flow rate of effluent hot water in the heat exchanger 4. Hereby, since the buzzer is actuated with the previous water amount before the water amount reaches the set water amount and hence the flow rate of effluent hot water are suppressed, a hot water supply state is checked with redundancy for adjustment thereof and even users unfamiliar with the use of the apparatus can supply hot water with ease for improvement of convenience.
