| Claim: |
1. A heating device comprising: a heat chamber to accommodate an object to be heated; a heater to heat up the heat chamber; an exhaust port formed with the heat chamber; an exhaust fan to eject air from inside the heat chamber through the exhaust port; a filter disposed at the exhaust port; a first temperature detector to detect a temperature in the heat chamber; a second temperature detector to detect a temperature of the air ejected from the exhaust port; and a controller to judge whether the filter is clogged or not based on a rotation number of the exhaust fan and a difference between the temperature of the air inside the heat chamber and the temperature of air which the second temperature detector detected. |
| Claim: |
2. The heating device according to claim 1 comprising: the heat chamber to accommodate the object to be heated; the heater to heat up the heat chamber; the exhaust port formed with the heat chamber; the exhaust fan to eject the air from inside the heat chamber through the exhaust port; the filter disposed at the exhaust port; the first temperature detector to detect the temperature in the heat chamber; and the second temperature detector to detect the temperature of the air ejected from the exhaust port, further including a third temperature detector to detect a temperature of the heater, wherein the controller judges whether the filter is clogged or not based on a rotation number of the exhaust fan, a difference between the temperature of the air inside the heat chamber and the temperature of the air which the second temperature detector detected, and the temperature of the heater which the third temperature detector detected. |
| Claim: |
3. The heating device according to claim 1, wherein the controller further includes an alarm. |
| Claim: |
4. The heating device according to claim 1, wherein the controller controls the rotation number of the exhaust fan and an output of the heater. |
| Claim: |
5. The heating device according to claim 4, wherein the controller controls the temperature in the heat chamber by at least; increasing the rotation number of the exhaust fan, when the temperature in the heat chamber reaches a predetermined temperature; decreasing the rotation number of the exhaust fan or stops the rotation of the exhaust fan, when the temperature comes down to another predetermined temperature; and increasing the rotation number of the exhaust fan, when the temperature is not come down to the another predetermined temperature. |
| Claim: |
6. The heating device according to claim 2, wherein the controller further includes an alarm. |
| Claim: |
7. The heating device according to claim 2, wherein the controller controls the rotation number of the exhaust fan and an output of the heater. |
| Claim: |
8. The heating device according to claim 7, wherein the controller controls the temperature in the heat chamber by at least; increasing the rotation number of the exhaust fan, when the temperature in the heat chamber reaches a predetermined temperature; decreasing the rotation number of the exhaust fan or stops the rotation of the exhaust fan, when the temperature comes down to another predetermined temperature; and increasing the rotation number of the exhaust fan, when the temperature is not come down to the another predetermined temperature. |
