BATHTUB APPARATUS

Japanese Patent JP2023124263

A

To provide a bathtub apparatus capable of appropriately adjusting temperature of hot water discharged from the discharge hole even in the bathtub apparatus supplying hot water in a bathtub by using a general hot water supplier.SOLUTION: A bathtub apparatus (1) has: a bathtub body (2); a water discharge device (8) provided above the bathtub body; a circulation flow passage connected to a water absorption port (9b) and the water discharge port (8a); a circulation pump (6) pumping hot water from the water absorption port to the water discharge port; a supply pipe (10) flowing water or hot water from a hot water supplier (52) into the circulation flow passage; a water amount sensor (24) capable of detecting a flow rate of the hot water supplied by the hot water supplier; and a controller (16) controlling inflow and stop of hot water into the circulation flow passage. When flow rate of hot water detected by the water amount sensor is a prescribed flow rate or less in the case that temperature of the hot water discharged from the water discharge port is raised, the controller decreases flow rate of water to be flown into the circulation flow passage from the supply pipe more than a flow rate of the hot water supplied by the hot water supplier, and drains surplus hot water.SELECTED DRAWING: Figure 3
