Description

The invention relates to combination ovens for space heating and cooking, equipped with double slab flooring separating the firebox from the overlying baking chamber. For the convenience of controlling the heating of the baking chamber, depending on its use, either as the baking chamber itself or as a hearth cooker, the bottom floor plate is provided with adjustable openings. Under the slab there is a rotary gate, with the help of which gases can be directed through the cavity between the floor slabs before they enter the furnace smoke intake system.

In FIG. 1 shows a longitudinal vertical section of the proposed center according to the aircraft of FIG. ten; FIG. 2 - in BB in FIG. ten; FIG. 3 - the same for explosives in FIG. ten; FIG. 4 - the same for GG in FIG. ten; FIG. 5 - plan of the hearth; FIG. b - horizontal section along P - II in FIG. one; FIG. 7 is the same on III - III in FIG. 1; FIG. 8 - the same according to IV - IV in FIG. 1: FIG. 9 is the same in V −V in FIG. one; FIG. 10 is the same for VI - VI in FIG. one; FIG. 11 - the location of the swivel lever that serves to control the gate; FIG. 12 - lifting iron valve baking chamber; FIG. 13 - flap section.

The center fire chamber, covered by double cast iron plate flooring 2, is divided in the middle part by a cast iron rotary gate 3 to reduce the volume of the firebox and the possibility of closing the rectangular opening # of plate 2 from the bottom side, through which hot gases from the firebox enter the interdisciplinary flooring space. The opening and opening of the hole 4 in the plate 2 from the bottom side is performed using the lever 7 with the handle 6, equipped with a counterweight 8 and connected with cables 9, 11 passed through the openings (windows) J2 on the block 10 (or lever transmission) with the gate 3. The drive to the gate is located in the retreat of the furnace between the wall / 5 and the side wall of the hearth. When the cable 9 is pulled, the lever 7 is deflected towards the block 10, the counterweight 9 moves to the opposite end of the lever (in Fig. 11, the position of the lever and the counterweight is shown when turning the gate) and holds the flap covering the opening 4 of the plate 2 while the hearth firebox "two increases; placing the gate 3 in a vertical position is carried out by means of a cable 11.

As a plate / it is applied ordinary type a plate with two rings. The underlying overlapping firebox 2 of the flooring plate has two rectangular openings 4 and 5, one of which 4 is closed by the gate 3, and the second 5 is closed on top of the plate by a cast iron gate 14, which moves between the ribs 15 poured to the plate. inserted into the cavity 16 of the valve 14 through the opening of the burner top plate. Above the slab flooring is a bakery chamber 17 with brick walls, closed by an iron lift gate 18.

Hot gases from the firebox first enter the hole 4 of the lower plate, wash the top cooker / dish for cooking food placed in the hole of the burner, pass between the plates, wash the second dish placed in the second hole of the top cooker hole, and sink into the hole 5 Next, the gases enter the second half of the firebox, blocked by the scraper 3, descend through the hole in the hearth of the firebox under the firebox and pass into the horizontal channel on the side of the hearth, from where they rise to the overlapping collecting channel at the top STI hearth. Lifting ducts, connected in series with each other, are located first in the rear part of the hearth, and then transferred to its front part. From the upper collector, the gases descend along four channels located in the side and rear walls of the hearth, are again united by a second horizontal collector, and pass through the pass under the baking chamber to the front.

foci and exit into the flue pipe, closed with a view. In the warmer months, the descending channels can be turned off by opening the valve 19, as a result of which gases from the first channel, not income until the channels are blocked, flow directly into the chimney.

The gases appearing during cooking on the stove in chamber 17 (chad and steam) are removed through the exhaust channel 20 connected to the blower, and the blown, equipped with an iron ash box, must be closed, and air to the fuel enters through the chamber 17, pulling gases appearing above the stove behind them, or these gases can be removed to the outside through an exhaust duct 2 / equipped with a valve.

The subject matter of the invention.
