The progress. Under the normal operation of the air pump device 3, the air inlet valve 45 and the air outlet valve 46, the heated air in the gas heating cavity 12 flows upward into the baking space 11 to maintain the air in the baking space 11 Baking temperature. The air in the baking space 11 will contain unclean components (such as volatile components of paint) as the baking process progresses, and the unclean hot air will flow upward into the air outlet cavity 13 and then into the internal air outlet duct 15 . Since the air outlet end of the internal air outlet pipe 15 communicates with the air pump pipe 32 and the air inlet space 411 of the air filter and exchange device 4, part of the dirty air in the internal air outlet pipe 15 will flow out of the air pump pipe 32 to the outside.

In addition, the room temperature air flowing into the intake space 411 from the external intake duct 43 will cause the mixing of the two The air temperature in the intake space 411 is reduced to a certain extent, but it is still maintained at a state higher than the room temperature. After the air in the intake space 411 passes through the filter net 42, the unclean components in the air can be filtered by the filter net 42 and then flow into the outlet space 412. A part of the air in the air outlet space 412 will flow out from the external air outlet pipe 44 to the external environment, so as to realize an external ventilation procedure, and another part of the air will flow into the internal air inlet pipe 14 and finally flow to the gas heating chamber Inside the body 12 for gas heating procedures. In the above-mentioned gas circulation and ventilation process, since the unclean components in the air are filtered through the filter 42 and a part of the gas in the baking space 11 is in and out of the outside air, it can ensure The degree of cleanliness of the gas in the baking space 11. On the other hand, since the air flowing into the gas heating cavity 12 is mixed with the high temperature gas (eg 200°C) flowing out of the baking space 11 and filtered from the external ambient air (eg 25°C), it can maintain At a temperature higher than room temperature to a certain extent (for example, 80°C), the heater 2 only needs to heat the air from the higher temperature (80°C) to the process temperature, not from a lower room temperature Start heating, because it can effectively save energy. Moreover, by adjusting the gas flow of the inlet valve 45 and the outlet valve 46, the ratio of intake and exhaust can be controlled, so as to adjust the ratio of the internal gas circulation and the external ventilation program to be suitable for different baking Application and operation of process conditions.

In summary, the new energy-saving baking equipment 100 of the present invention can effectively reduce the energy consumption caused by the operation of the heater 2 and maintain the baking space through the drive of the air pump device 3 and the configuration of the air filter exchange device 4 The cleanliness of the air within 11 can indeed achieve the purpose of new cost.
