Description

The proposed further modification of the device for heating the oven with a burner of the Primus type, described in patent No. L 12082 (as reference number 77530), aims to make full use of the heat supplied by this burner to a more uniform dough closet To achieve this goal, a detachable cap is used, which serves to warm the air and reflect radiant heat from the burner and the bottom of the casing towards the furnace space, as well as holes in the bottom or walls of the cabinet to draw steam out of it into the exhaust gas channel. In addition, a flange is provided at the bottom of the casing, directing the air washing the bottom through a detachable cap to the burner.

In FIG. 1 shows a vertical section of a brass oven; FIG. 2 is a top view, partly in section; FIG. 3. 5- longitudinal sections of the split cap, FIG. 4 is a top view, FIG. 6 and 7 illustrate ways of cap removal and FIG. 8-piece

connect the walls of the casing, shield and oven.

The furnace stove consists of a four-sided duct 5 (Fig. 1), sloping from the center of the lid 13, on which horizontal platforms 15 were stamped (Fig. 1, 2) with brackets 16 attached to them, and from the bottom 12 the edge of the duct welded to the machines 5, the lid 5 has in its center a hole with a collar representing a branch pipe for flue gases, which is covered by a lid 1 riveted to the collar with three strips, so that between the collar l and the lid an annular gap is formed for the passage of flue gases; the cover 17 is made convex and prevents water droplets from condensation of water vapor in the exhaust gases from entering the furnace. The cover 13 at the bottom is insulated with an asbestos gasket 14, and the bottom 13 is insulated with a gasket 17 made of asbestos or refractory clay. Inside the box 3 there is another box, which serves as a reflective shield, and has its walls S parallel to the walls.

the box 6 and autogenous are welded to the lower ones, whereby in the space 6 between the walls of the box 5 and the shield 2 there is a heat supply medium, for example, ash, air. The oven 1, placed inside the oven, is a rectangular parallelepiped, one face of which serves as a door. The space between the walls of the oven 1 and the shield 2 has a space through which gases move in the direction of the arrows 29. Stops, 9, 1U and 11, which do not give a baking tray mounted on spikes S or a skid 7, come into contact with the walls, are attached to the walls of the oven 1, and thus the walls of the cabinet and the baking sheets form a space through which gases can move. In the bottom of the cabinet, a hole A is arranged, which communicates the space of the oven with the space formed by the hearth of the oven and the visor 4; the latter, with its vertical walls, is attached through the spacers to the walls of the oven, so that a slit 4 is formed between the walls of the cabinet and the visor (Fig. 2). The legs 19 on which the entire furnace is resting are attached to the furnace casing from below. From below to the bottom 2 of the casing, the split cap shown in FIG. 3, 4, 5, 6 and 7, which serves to reflect the rays coming from the Primus burner in all directions into the furnace space. The cap consists of two cones 23 and 82, which enter one another, terminating at the top and bottom with the shoulders 26, 24 and 25, 27. The shoulders 26, 2 and 24, 25 are fastened together by means of gaskets so that annular rings are formed between them. - slots, and the entire cap, by means of the collar 26, is riveted to the bottom 12 of the casing. The cap is made for the legs of the burner "Primuo slots 28, located at an angle of 120 ° to each other. A cap is fitted along these slots and made in a double way, as shown in FIG. 6 and 7. The movable part of the cap is divided along the lines aa (Fig. 3) by two notches 56, and directed to the bracket 21 (Fig. 2) of the door 20 and, together with the latter, during the entry into the burner cap, the Primus moves away and moves towards the stationary parts of the cap. During the operation of the oven, the gases, moving along arrow 29, heat the walls of the oven 1 and exit into the opening of the lid 13, and heat the supplied

on staples 16 vessel with food or water. The dough put in the oven 1 in the baking pans mounted on spikes 8 or skid x 7, on the left of the cabinet, gradually builds up. The vapors formed during the baking of the dough, pulled out through the opening A., move along the walls of the cabinet downward and cool the edges of the nasty and dough, thus saving the latter from excessive heating and burning; due to the same pairs collected above the bottom of the cabinet, the dough on the pan mounted on the spikes 8 is prevented from burning. The vapors pulled through opening A into the space between the hearth and the visor 4 pass through the slot 4 into the space between the walls of the cabinet 1 and shield 2, and continue to move along with the gases in the direction of the arrow 29. Thus, water vapor formed from dough, firstly, regulates the temperature in the oven 1, preventing the edge and the lower part of the dough from burning, and, used to heat the vessel supplied th on the brackets 16 of the lid 13. The air required for combustion is supplied through the gap between the ribs 26,27, then irohodit between cones 23 and 22 and through the gap between shoulders 24,25 to the burner "Primus. On the continuation of the entire described path, the air is heated, taking heat from the wall 12 of the furnace shell and the detachable hood, and this increases the temperature of the burner flame.

The subject of the patent.

1. The modification of the device for heating the oven valve specified in patent No. 12082 with a burner of the type Primus, characterized in that the lamp into which the Primus is inserted is designed as a detachable cap (Figs. 3, 4, 5, 6 and 7), the Primus surrounding the burner and consisting of a fixed part 23 attached to the bottom 12 of the oven casing and a movable part, the movement of which allows the burner and the Primus legs to be inserted into and removed from the hood to communicate the same with; a under the bottom 12 of the air in the upper part of the cap, at its junction with bottom 12, there are gaps.

2. The form of execution specified in. Clause 1 of the tool, characterized in that the oven chamber 1 (Fig. 1-2) communicates with the nozzle which removes the hot gases through one or more openings A B or in the walls of the duvet.

3, When adapting but pp 1-2 application of the rim, in the form of a vertical rim, surrounding the bottom of the IS in place, connecting it to the walls 5.
