A heating apparatus includes a ceramic heater including a plurality of ceramic plates having a plate shape, and a housing including an inlet hole and an outlet hole, the housing in which the ceramic heater is installed. The ceramic plates are disposed vertically in the housing in a parallel manner and the outlet hole is disposed in an upper portion of the housing, such that when a fluid flows through a flow path formed along the ceramic plates, bubbles, generated by the fluid heated by the ceramic plates, ascend toward edges of the ceramic plates.

1. A heating apparatus comprising: a ceramic heater including a plurality of ceramic plates having a plate shape; anda housing including an inlet hole and an outlet hole, the housing in which the ceramic heater is installed, the outlet hole being disposed higher than the inlet hole,wherein the ceramic plates are disposed vertically in the housing in a parallel manner and the outlet hole is disposed in an upper portion of the housing such that when a fluid flows through a flow path formed along the ceramic plates, bubbles, generated by the fluid heated by the ceramic plates, ascend toward upper edges of the ceramic plates,wherein the ceramic plates are fixed to a fixing member disposed at a first side of the housing,wherein a gap is defined between upper ends of the ceramic plates and the housing such that the bubbles ascending towards the upper edges of the ceramic plates are placed in the gap before discharging through the outlet hole, thereby preventing the bubbles from contacting the ceramic plates,wherein the heating apparatus is inclined such that a side of the outlet hole is placed at the upper portion to allow the bubbles generated by the fluid by heating to be discharged through the outlet hole. 2. The heating apparatus of claim 1, wherein the ceramic heater comprises: a first ceramic plate disposed adjacent to the inlet hole; anda second ceramic plate disposed adjacent to the outlet hole,wherein a partition wall is installed between the first ceramic plate and the second ceramic plate. 3. The heating apparatus of claim 2, wherein the first ceramic plate and the second ceramic plate are attached to the first side of the housing and spaced apart from a second side of the housing, and the partition wall is attached to the second side of the housing and spaced apart from the first side thereof. 4. The heating apparatus of claim 1, wherein the flow path is widened from the inlet hole toward the outlet hole. 5. The heating apparatus of claim 1, wherein the ceramic plates have an area that is greater than a cross-section of the flow path. 6. The heating apparatus of claim 1, wherein heating wires are installed inside the ceramic plates and disposed at the center of the ceramic plates in a thickness direction, respectively. 7. The heating apparatus of claim 2, wherein power applied to the first ceramic plate is different from power applied to the second ceramic plate. 8. The heating apparatus of claim 7, wherein the power applied to the second ceramic plate is higher than the power applied to the first ceramic plate. 9. The heating apparatus of claim 7, wherein fixed power is applied to the first ceramic plate and variable power is applied to the second plate.
