DISCLOSURE OF THE INVENTION

The basic task of the invention was to create a large householder for electric appliances, which would have a high resistance to heat and iron.

This task is addressed by the fact that in the case of a heating unit for the electric furnace, which contains the body and the external unit with the cooling system, there is an

Consumable element 9 also has a drawback, and a socket 14 is installed on the threaded port, having a channel 15 and a non-exhausting port 13

20 incidents (not shown otherwise). The bulk elec- trode I is connected to the niche 14 threaded 17.

The element 9 has a cylindrical part 18 with an external diameter, equal to the internal diameter of element b, and a cylindrical part 19. less than the first

25 (18), diameter, and obrazu _. There is an element with a compartment 7 and an area of 20, in which a compartment mounted in the form of a receptacle 21 is located.

At the bottom of step 21, there are two openings, after some 4 and 5, and 5, there are 5

Unit 22 is delivered with a volume of 23 units 2 to remove water in the process of cooling the unit.

The mains I with nipple 14 are screwed into

35 element 9 of the front node 3, and this unit 4 and - 4 - Channels 15 and 16 must be communicated. Then, the electric I is installed in the electric furnace.
