1. An induction heater, comprising:
- an inverter body having an inlet formed in a bottom surface thereof;
an inverter circuit board provided within the inverter body;
an inverter heat dissipater mounted in the inverter body and contacting the bottom surface of the inverter body such that an inlet of the inverter heat dissipater is connected to the inlet of the inverter body, wherein the inverter heat dissipater is configured to blow air to a front and a rear of the inverter circuit board, the inverter heat dissipater comprising;
an inverter heat dissipation blower configured to blow air into at least one of a first inverter heat dissipation space formed between the inverter body and the inverter circuit board or a second inverter heat dissipation space formed between the inverter body and the inverter circuit board; and
an inverter guide provided between the inverter body and the inverter circuit board and configured to guide air blown by the inverter heat dissipation blower to the inverter circuit board; and
a heat sink provided on a top surface of the inverter circuit board, wherein the heat sink dissipates heat from the inverter circuit board, and wherein an outlet divider divides an outlet of the inverter heat dissipation blower so that more air is blown into the first inverter heat dissipation space than into the second inverter heat dissipation space, andwherein the inverter guide comprises a plurality of guide ribs each having an end portion thereof that is closest to the heat sink bent toward the heat sink.

Abstract
Provided is an induction heater which induces an electric current in a metal utensil (e.g., a cooking utensil) using an electromagnetic force and can thus heat the metal utensil, and more particularly, an induction heater which can prevent electric devices sensitive to temperature from being overheated by forcefully blowing air to the front and the rear of an inverter circuit board. The induction heater is easy to be miniaturized, and a considerable number of devices can be integrated into the induction heater.

15. An induction heater, comprising:
-
an inverter circuit board; an inverter body which defines a space configured to receive the inverter circuit board, the inverter body having an inlet formed in a bottom surface thereof; a heat sink provided on a top surface of the inverter circuit board, wherein the heat sink dissipates heat from the inverter circuit board, and wherein an outlet divider divides an outlet of an inverter heat dissipation blower so that more air is blown into a first inverter heat dissipation space than into a second inverter heat dissipation space, the first and second inverter heat dissipation spaces each being formed between the inverter circuit board and the inverter body; and an inverter heat dissipater mounted in the inverter body and contacting the bottom surface of the inverter body such that an inlet of the inverter heat dissipater is connected to the inlet of the inverter body, wherein the inverter heat dissipater is configured to blow both a main air stream to a first portion of the inverter circuit board and a sub-air stream to a second portion of the inverter circuit board, wherein the inverter heat dissipater includes an inverter guide provided between the inverter body and the inverter circuit board and configured to guide air blown by an inverter heat dissipation blower to the inverter circuit board, and wherein the inverter guide comprises a plurality of guide ribs each having an end thereof that is closest to the heat sink bent toward the heat sink. - View Dependent Claims (16, 17)
