Abstract
The disclosure provides a water heater. The water heater includes a water heater main body portion including a heat exchanger and a combustion device; a fan and a motor for driving the fan; an exterior case; and an air supply adapter mounted to an upper wall portion of the exterior case. The combustion device and the motor are positioned in a region near an upper portion within the exterior case. The combustion device is at least partly positioned between the air supply adapter and the fan in a plan view. An air outlet of the air supply adapter opens substantially horizontally, avoiding a direction directly facing the motor. The air flowing out from the air outlet is changed in direction by a side wall portion of the exterior case and flows to reach a portion of the motor.
Claims10
A water heater, comprising:
- a water heater main body portion comprising a heat exchanger for heating water and a combustion device for supplying combustion gas to the heat exchanger;
- a fan for supplying a mixed gas or an air for combustion to the combustion device and a motor for driving the fan;
- an exterior case having an upper wall portion and a side wall portion forming a housing space for housing the water heater main body portion, the fan, and the motor;
- and
- an air supply adapter mounted to the upper wall portion and having an air outlet for having outside air flow into the exterior case;
- wherein the combustion device and the motor are positioned in a region near an upper portion of the water heater within the exterior case, and the combustion device is at least partly positioned between the air supply adapter and the fan in a plan view, and
- the air outlet of the air supply adapter opens substantially horizontally, avoiding a direction directly facing the motor, and the air flowing out from the air outlet is changed in direction by the side wall portion of the exterior case and flows to reach a position of the motor,
- wherein the air outlet is configured to face the side wall portion at an oblique angle that deflects air flowing out from the air outlet around an exhaust duct of an exhaust gas flow passage forming member and into the side wall portion, wherein the side wall portion in turn deflects air to the position of the motor.
