Abstract
Disclosed is an air heating apparatus including an expansion tank which preserves water, a water heater which receives heat from a combustion gas generated through a combustion reaction and heats the water, a heating heat exchanger which receives the water heated by the water heater and exchanges heat with air that is to be discharged for heating, a fan which sends the air to the heating heat exchanger, and a case, in which the water heater, the expansion tank, the heating heat exchanger, and the fan are disposed in an interior thereof.
Claims17
An air heating apparatus comprising:
- an expansion tank configured to preserve water;
- a water heater configured to receive heat from a combustion gas generated through a combustion reaction and heat the water;
- a heating heat exchanger configured to receive the water heated by the water heater and exchange heat with air that is to be discharged for heating;
- a fan configured to send the air to the heating heat exchanger;
- and
- a case, in which the water heater, the expansion tank, the heating heat exchanger, and the fan are disposed in an interior thereof,
- wherein the case includes:
- an outer box having a first opening in a reference direction that is one direction that is perpendicular to an upward/downward direction;
- a first opening cover coupled to the outer box and covering the first opening when being coupled to the outer box;
- a first partition wall coupled to the outer box, and extending along the reference direction to divide an interior of the outer box to a first division space and a second division space;
- a second partition wall disposed in the interior of the outer box to be perpendicular to the first partition wall to divide the first division space to a (1-1)-th division space and a (1-2)-th division space;
- and
- a third partition wall disposed in the interior of the outer box to be perpendicular to the first partition wall to divide the second division space to a (2-1)-th division space and a (2-2)-th division space, and
- wherein the second partition wall and the third partition wall may be separated from the interior of the outer box;
- wherein the second partition wall is coupled to the interior of the outer box to be separable;
- and
- wherein the third partition wall is coupled to the interior of the outer box to be separable.
