ELECTRIC FURNACE Russian patent published in 2023 - IPC A61H33/06 

FIELD: electrical engineering.

SUBSTANCE: design of an electric heating device intended for heating and steam generation used for equipping baths and saunas. The electric furnace consists of a body with a lid, inside of which there are electric heating coils in a convector heater with heat-insulating walls and a heater module with heat-accumulating elements, a convection channel, the convection channel body is fixed on the back wall of the furnace body, the convection heater inside the body is located under a closed heater, with an internal electrically insulating material is fixed on the sides of the convector heater walls, the front wall of the convector heater has convection holes, the rear part of the convector heater enters the hole in the rear panel of the convection channel box, on the lid of the furnace body there is a bowl of the outer heater and a convection grill, against which the hole of the convection channel box rests, the hole at the bottom of the bowl of the outdoor heater, it has a branch pipe from the inside, the body of the closed heater with a lid is protected by heat-insulating material, inside the closed heater there is a structure made of shaped pipes with row of holes, insulated heating elements, temperature sensor, in the lid of the closed heater there is a number of slots with a nozzle above them, turned towards the convection channel box, the upper edge of the rear panel of the convection channel box is made flush with the lid of the closed heater.

EFFECT: creation of a structure that provides a stable high-temperature regime for heating heat-storage elements of a closed heater.
