HIGH-FREQUENCY CURRENT HEATING DEVICE Russian patent published in 2014 - IPC F24C7/02 

FIELD: heating.

SUBSTANCE: invention relates to a high-frequency current heating device with a heater. The high-frequency current heating device includes a heating chamber, into which a heating object is placed, a rotating turntable made on lower surface of the heating chamber, onto which a heated object is arranged so that it can be rotated, a high-frequency current heating section that heats up the heated object that is arranged in the heating chamber, a circulation fan casing arranged above the upper surface of the heating chamber, the first heater for heating of the heating chamber, which is located inside the circulation fan casing, a circulation fan to provide the heating chamber with heat from the first heater in the form of hot air, which is located inside the circulation fan casing, inlet air holes for drawing the air inside the heating chamber by means of rotation of the circulation fan, which are made at the front on the right side on upper surface of the heating chamber, outlet air holes to supply the air to the heating chamber by means of rotation of the circulation fan, which are made at the back on the right side on upper surface of the heating chamber, the second heater for heating of the heated subject, which is located on the left side of upper surface of the heating chamber and installed at an inclination angle in the backward direction above upper surface of the heating chamber, at least one radiation hole made on upper surface of the heating chamber under the second heater and passing at an inclination angle in a backward direction on the left side of upper surface of the heating chamber; with that, radiation heat is supplied diagonally from the heated subject side, a reflector made around the area above the second heater, an insulating panel closing from above the first heater and the second heater for hot air isolation from the first and the second heaters, a convection unit including inlet air holes and outlet air holes to provide hot air circulation in the heating chamber; with that, the first and the second heaters are located relative to each other on upper surface of the heating chamber, and inlet air holes, outlet air holes and radiation holes are located in places out of the centre of the heating chamber.

EFFECT: providing uniform heating, improving preparation efficiency and reducing external shape of the device.
