(54) HEATING AND COOKING OVEN

II

The invention relates to a combined heating-cooking stoves, working on a solid top, designed for individual houses and country houses.

Known heating-cooking stoves with two furnaces: the main - for heating and additional (formed on) - for cooking, located one under the other and having one common gas duct.

Closest to the proposed heating and cooking furnace, comprising a housing with slab flooring, one below the other main and additional fireboxes connected by a duct, a damper installed in the duct, and a common flue with flap 3.

A disadvantage of the known furnaces is the limited ability to separately control the intensity / combustion when the furnace is operated in a combined mode. So, intense selection

gases from the lower firebox drowns out and ae barks impossible weak burning in the upper firebox. For the same reason, the ignition of the upper furnace is also difficult. At the same time, any kind of prolonged opening of the upper furnace door (for example, for igniting) leads to attenuation of the burning in the lower one, since in this case the air inflow under the lower grate decreases sharply.

The purpose of the invention is to improve the operation of the furnace by providing separate control of the operation of the main and additional furnaces in the combined mode of operation of the furnace.

This goal is achieved by the fact that in a heating-cooking furnace containing a housing with slab flooring, one above the other main furnace and an additional JQ firebox, as well as a common chimney with a flap, the common chimney is equipped with a partition dividing it into two independent channels with autonomously operating dampers, each of the autonomous

channels connected to the corresponding furnace.

In addition, the firebox is equipped with a pivoting wall connecting the autonomous channels of the common chimney with the corresponding firebox.

At the same time, the regulation of the gas flow in each channel is carried out autonomously with ps with the help of independently operated dampers.

FIG. 1 shows the proposed furnace, a longitudinal section in FIG. 2 - the same, cross section.

The kiln contains Kdpnyc 1 with a ribbed stile 2 finned from below, water jacket shielded 3 main furnace 4 with grate 5, additional furnace b limited laterally by the walls of plate nartila, grate heat exchanger 7 additional furnace connected with heat and ampoule and a water-jacketed collector 8, swiveling jets 9, a 1O flue, a rear swiveling wall 11 of an additional fire, a common chimney 12 divided by a partition 13 into two autonomous channels with flaps 14 and 15, an blowing chamber 16 formed When closing zhelyuzi. The surface of the additional firebox is provided with heat insulation 17, and the heat insulation of the United Nations fire chamber is formed by an air net 18 between the case and the water jacket. The slab flooring is closed with reclining for the cooking time. Write a thermally insulated lid 19. On the front side of the furnace there are loading doors 20 and 21. The injection holes 22 with a gate are made on the front panel of the ash drawer 23. On the door 21 there is an air valve 24 for air to pass under the upper grate lattice. The operation of the furnace is possible in any of the three modes: heating, cooking, and combined (heating-cooking). In the heating mode, the pivoting wall 11 is set to position a. Fuel is loaded through the door 20 and burned on the grate B of the main firebox 4. Air enters the fire chamber through the blower holes 22 in the hall holder 23, then passes under it, heats up and enters the colo-nets. The valve 15 is placed in the half-open position, and the valve G 14 is in the fully open position. Pozhelishche zhelyuy 9 nyhod ts in the open (verti-.

the total) position. The air valve 24 is closed. The flue gases, divided into two streams, pass through the grate-heating element 7 and the flue gas duct.

1O. The flue gases exit through both channels of the common chimney 12. At the same time, the heat of combustion is effectively absorbed by the water jacket 3, the heat-exchanger grill 7 with the collector 8 included in

common water circuit heating, and the surface of the flue 10.

In the combined mode, the pivot wall 11 is set to position a. The fuel is simultaneously burned on the grates 5 and 7. Depending on the need, the shutters 14 and 15 are set to any open position, thereby ensuring independent control of the intensity of burning in both furnaces within wide limits, jets 9 are brought to horizontal (closed) position forming a blower chamber 16 for the cooking chamber. The air valve 24 is open: the heat shield 19 flips out, providing access to the slab floor 2. Accessing both furnaces is autonomous: the additional one through the valve 24 and the blower chamber 16, where it is partially heated and fed under the grate 7, into the main grate the same as in the heating mode. The flue gases of the upper furnace 6 are directed to the ribbed floor board 2 and leave the furnace through the upper channel of the common flue 12. The flue gases of the main furnace 4 pass through the flue 10 and the lower flue channel 12, mine the furnace 6. Ignition the upper furnace and transfer from the combined mode to the heating system occurs when the valve 14 is partially open, which eliminates the breakthrough of a large amount of cold air and violation of traction in the heating path. At the end of cooking, the turning wall 11 is FUSED to position B, and the fuel remaining on the upper grate is discharged to the lower grid 5 via the iO flue, after which the turning wall 11 is positioned in position c. Blinds 9. In the cooking mode, the pivot wall 11 is in position d. The fuel is burned on the grate 7. The valve 14 and the air valve 24 are open. The valve 15 and the blowing holes 22 are closed. The blinds 9 can be either closed or open ytom position. The air enters the furnace through valve 24 under the grate 7- Ti pochnye gases exit only through the upper flue passage 12,

In addition to providing separate control over the operation of the main and additional fireboxes, the proposed furnace has additional advantages due to the implementation of the slab flooring 2 with ensuring thermal contact with the walls of the additional firebox 6. Such a design allows the temperature of the slab to be significantly increased, burning heat, burning the walls are intensively transmitted to the surface of the slab flooring, where it is removed by a heated tank. This circumstance alleviates the requirements for thermal insulation of the side panels on top of the cue stove.

In addition, the presence of a highly developed heat-absorbing surface of the flooring due to the side walls and finning makes it possible to use it for heating pshdi in the heating mode.
