Claims

[Scope of utility model registration request]

Heat exchanger 1 for hot water supply combined with burner 11 for hot water supply
In a bathtub with a water heater, in which a bath heat exchanger 2 combined with a bath burner 21 is housed in a vessel body 3, and exhaust from these combustion parts is discharged from an exhaust port. A bath heat exchanger 2 combined with a bath burner 21 is disposed close to one side wall of the lower part of the body 3, and a hot water heat exchanger 2 combined with a hot water supply burner 11 is disposed close to the other side wall of the upper part of the body 3. A forced exhaust fan 22 is provided above the bath heat exchanger 2, and an air supply fan 12 is provided below the other hot water supply heat exchanger 1. An exhaust port 52 extending in the width direction is provided at the upper end, and this exhaust port is opened at the front of the vessel body 3, and the exhaust box 55 at the upper end of the hot water supply heat exchanger 1 is connected to the exhaust port 52. At the same time, the discharge port of the forced exhaust fan 22 is communicated with the exhaust port section 52 through the communication pipe 23 along the rear wall of the vessel body 3, and the hot water supply fan 22 is connected to the side of the bath heat exchanger 2. The gas control parts group 81 is arranged centrally in the space formed below the heat exchanger 1, and the water system is arranged above the bath heat exchanger 2 and in the space on the side of the hot water supply heat exchanger 1. control parts group 8
2 are centrally arranged, the water supply connection part 83 and the hot water supply connection part 84 are made to protrude from the side wall adjacent to the arrangement part of the control parts group 82, and the gas connection part 85 is made to protrude, and from the said gas connection part 85 A gas communication pipe 86 is disposed across the gas control parts group 81, and the gas communication pipe 86 extends from near the upper part of the bath heat exchanger 2 to the gas control parts group 81, and a control board equipped with electrical parts. 4 is disposed below the hot water supply heat exchanger 1 near the side wall adjacent to the hot water supply heat exchanger 1.
