Description

An electromagnetic cooker

Technical Field

The utility model relates to the field of electromagnetic cookers, in particular to an electromagnetic cooker with excellent heat dissipation.

Background Art

The principle of induction cooker is electromagnetic induction, that is, using alternating current to pass through the coil to generate an alternating magnetic field with constantly changing direction. Eddy current will appear inside the conductor in the alternating magnetic field. This is because the eddy electric field drives the movement of carriers in the conductor; the Joule heating effect of the eddy current causes the conductor to heat up, thereby achieving heating.

In the prior art, a heat dissipation fan is usually arranged inside the induction cooker to prevent the induction cooker panel from overheating and affecting its service life. The induction cooker vents in the prior art are usually arranged at the sides and bottom of the induction cooker. The heat dissipation fan in the induction cooker inhales cold air from the vents at the bottom and discharges hot air from the vents at the sides. A portion of the hot air flowing outward from the sides will be sucked into the induction cooker housing from the bottom vents again, resulting in reduced heat dissipation performance, which greatly affects the service life of the induction cooker. How to improve the heat dissipation performance of the induction cooker is a technical problem to be solved by the utility model.

1 to 4, an embodiment of an induction cooker of the present invention is provided:

An induction cooker includes a shell 1 and a panel 2. A coil disk 3, a control circuit board 4, and a cooling fan 5 are installed in the shell 1. The coil disk 3 is located above the control circuit board 4 and the cooling fan 5. The bottom of the shell 1 includes a support surface 11 and a recessed area 12 formed by a recess and lower than the support surface 11. The recessed area 12 is located in the front half of the bottom of the shell 1. Support parts 13 are provided on both sides of the front end of the recessed area 12. The induction cooker is supported by the support surface 11 and the support part 13, and the support is stable.

The front middle part and the left and right sides of the recessed area 12 are horizontally connected to the outside of the housing 1 , so that air can flow into the recessed area 12 from the front part and the left and right sides of the recessed area 12 .

A three-dimensional air inlet cover 14 protruding downward and communicating with the inner cavity of the housing 1 is provided in the recessed area 12. The heat dissipation fan 5 is fixed above the air inlet cover 14 through a bracket. An air outlet slot 15 communicating with the inner cavity of the housing 1 is provided on the rear wall of the housing 1. The control circuit board 4 is located between the heat dissipation fan 5 and the air outlet slot 15. When the heat dissipation fan 5 is started, air enters from the air inlet cover 14 and exits from the air outlet slot 15. The air flow in the inner cavity of the housing is accelerated by the heat dissipation fan 5 to achieve the purpose of heat dissipation. The support surface 11 is blocked between the air inlet cover 14 and the air outlet slot 15, thereby preventing the hot air discharged from the air outlet slot 15 from mixing from the bottom and being sucked into the housing 1 again by the heat dissipation fan 5. The blocking of the air inlet area and the air outlet area can improve the heat dissipation performance of the induction cooker.

The air inlet cover 14 includes a lower air inlet surface located at the bottom surface and side air inlet surfaces arranged around the lower air inlet surface. The lower air inlet surface and the side air inlet surfaces have air inlets arranged in a turbine shape, which vortex the air inlet and increase the air inlet speed.

An airflow guide wall 6 is installed in the housing 1. The airflow guide wall 6 surrounds the outer periphery of the cooling fan 5. The airflow guide wall 6 has an air guide port facing the air outlet slot 15. The control circuit board 4 is located between the air guide port and the air outlet slot 15. The airflow guide wall 6 guides the airflow to flow in the direction of the air guide port, and blows air to the control circuit board 4 in a concentrated manner.

A heat sink 41 is provided on the control circuit board 4. The heat sink 41 has a plurality of heat sinks. The heat sinks are spaced to form heat sink grooves. The heat sink grooves are opposite to the air guide ports. The heat sink 41 quickly removes the heat from the control circuit board 4. The heat sink increases the heat dissipation area. The heat sink allows air to pass through the air sink to quickly remove the heat. The heat dissipation performance is further improved by providing the heat sink 41.

The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
