Heat dissipation structure for smoke-exhausting induction hob

Abstract

This invention relates to a heat dissipation structure for a smoke-exhausting induction cooker, comprising a main body, a power module, a heat conductor, a shielding structure, and a smoke exhaust fan. The main body includes an air guide seat and a panel covering the air guide seat. The air guide seat has an accommodating space and a smoke exhaust duct. The panel has an opening in the duct that connects to the smoke exhaust duct. The power module, comprising a circuit board and a coil, is disposed within the accommodating space. The heat conductor thermally conducts heat to the circuit board and protrudes into the smoke exhaust duct. The shielding structure surrounds the periphery of the port of the smoke exhaust duct and separates the accommodating space from the smoke exhaust duct. The smoke exhaust fan is electrically connected to the circuit board, disposed on one side of the air guide seat, and connects to the smoke exhaust duct; thereby achieving smoke exhaust and heat dissipation for the power module, while reducing costs.

Claims

1. A heat dissipation structure for a smoke-exhausting induction cooker, comprising: a body including an air guide seat and a panel covering the air guide seat, the air guide seat having an accommodating space and an oil fume duct communicating with the accommodating space, the panel having an air duct opening communicating with the oil fume duct; a power module disposed in the accommodating space, including a circuit board and at least one coil electrically connected to the circuit board; a heat conductor thermally connected to the circuit board and protruding into the oil fume duct; and a shielding structure surrounding the periphery of the port of the oil fume duct and separating the accommodating space and the oil fume duct; and a smoke exhaust fan electrically connected to the circuit board, disposed on one side of the air guide seat and communicating with the oil fume duct, wherein the smoke exhaust fan generates airflow when operating to draw out air from the oil fume duct and simultaneously remove heat from the heat conductor, thereby dissipating heat from the power module.

2. The heat dissipation structure of the exhaust-type induction cooker as described in claim 1, wherein the air guide base includes an air guide pipe that connects to the oil fume duct, and the exhaust fan is disposed at the end of the air guide pipe facing the external environment.

3. The heat dissipation structure of the exhaust-type induction cooker as described in claim 1, wherein the heat conductor includes a heat-conducting side and a heat dissipation side perpendicular to the heat-conducting side, the heat-conducting side is attached to the circuit board, and the heat dissipation side protrudes into the fume duct.

4. The heat dissipation structure of the exhaust-type induction cooker as described in claim 3, wherein the heat conductor is provided with a plurality of protrusions on the heat conduction side, the circuit board is provided with a plurality of through holes, and the heat conductor is positioned on the circuit board by inserting the protrusions into the through holes.

5. The heat dissipation structure of the exhaust-type induction cooker as described in claim 3, wherein the heat conductor has a groove on the heat conduction side, and the heat conductor abuts against the circuit board through the groove, thereby causing the heat dissipation side to protrude into the fume duct.

6. The heat dissipation structure of the exhaust-type induction cooker as described in claim 1, wherein the shielding structure includes a plurality of partitions that surround the periphery of the port of the fume duct, thereby forming the shielding structure.

7. The heat dissipation structure of the exhaust-type induction cooker as described in claim 6 further includes a heat sink assembly, wherein the heat sink assembly is detachably attached to the heat dissipation side of the heat conductor and frames a portion of the periphery of the port of the fume duct, thereby forming the shielding structure with the partitions.

8. The heat dissipation structure of the exhaust-type induction cooker as described in claim 1 further includes a heat sink assembly, which is detachably attached to the heat dissipation side of the heat conductor, and the heat conductor and the heat sink assembly extend from one end of the port of the fume duct to the other end, thereby forming the shielding structure.

9. The heat dissipation structure of the exhaust-type induction cooker as described in claim 8, wherein the heat sink assembly includes a base plate and a plurality of fins, the base plate being attached to the heat dissipation side of the heat conductor, and the fins being arranged parallel and spaced apart on the base plate.

10. The heat dissipation structure of the exhaust-type induction cooker as described in claim 8, wherein the heat sink assembly further includes a plurality of fasteners, the heat sink assembly being connected to the heat dissipation side of the heat conductor through the fasteners.
