Description

The utility model relates to energy, in particular, to devices for heating household and utility rooms and cooking.

A device is known from the prior art according to US patent US4856491 "High efficiency solid fuel burning stove" (IPC F24B1 / 02; F24B13 / 00; F24B5 / 02; published 15.08.1989). The known furnace contains a body containing a front and a back walls, inner and outer side walls, an upper and a lower base, a door with a glass panel and legs. In the upper part of the body there is a branch pipe for connection to a chimney. The upper base includes a removable grate that allows fuel to be loaded into the combustion chamber from above. In the lower part of the body there is an ash pan and a grate with holes allowing ash to drain into the ash pan. The disadvantage of this solution is the absence of holes and valves in the furnace to regulate the oxygen supply, which makes it difficult to control the combustion level. Moreover, the oven does not have a hob, therefore, it is not suitable for cooking. In contrast to this technical solution, in the declared heating and cooking furnace, holes with a latch are made in the door to regulate the air blowing into the combustion chamber, and the furnace body also includes a cooking surface in which a burner is made.

From the prior art, a solution is known for a patent for a utility model RU 121 037 U1 "SOLID-FUEL FURNACE-PLATE" (IPC F24B 1/00; published 10.10.2012), selected as the closest analogue. The known stove-plate contains a steel body, consisting of vertical walls reinforced with ribs and cooling, a cooking floor with burners. At the bottom of the body there is a branch pipe for connection to a chimney. In the front part of the furnace, there is a door for loading fuel and servicing the furnace chamber, made of glass ceramics. An ash pan serves to adjust the intensity of combustion, the width of the opening gap regulates the flow of air into the combustion chamber of the furnace. However, this design does not provide a smooth adjustment of the combustion mode, including its intensity. In contrast to the analogue, the declared heating and cooking stove in the door contains holes with a valve to regulate the air supply to the combustion chamber, which ensures more accurate regulation of the oxygen supply and the combustion level, firewood and coals burn out to a greater extent, leaving a small amount of soot.

The objective of the proposed technical solution is to create a heating and cooking furnace that provides the most accurate dosing of oxygen and allows you to select and maintain optimal combustion modes. The technical result of the proposed solution is to increase the energy efficiency of the furnace, by improving the heat capacity and efficiency. The claimed technical result is achieved by optimizing the combustion parameters, due, in particular, to an increase in the accuracy of regulating the oxygen supply and the speed and direction of the flue gases.

The claimed technical result is achieved in that in a heating and cooking furnace comprising a body formed by walls, a cooking surface in which the burner is made, and a base, forming a combustion chamber inside the body, a branch pipe made in the upper part of the body for connecting to a chimney and located under a flame arrester, a door with a window fixed in the wall of the body, a hole made in the base of the body, with a grate installed in it, under which the ash chamber is located, holes with a gate valve are made in the door to regulate air blowing into the combustion chamber, and the damper is made at an angle to the cooking surface, while a partition is made on the cooking surface in the inner space of the body. The gate valve for regulating the air supply can be made as a gate valve. The wall of the casing may contain openings above the door with a slide latch to regulate the blowing of the door. The door may contain a heat-resistant cord fixed around its perimeter. The base of the body is made with legs. The body can be made of gray cast iron. The walls of the body may include an embossed surface.

The heating and cooking stove comprises a housing formed by walls, a cooking surface in which a burner is made, and a base, which form a combustion chamber inside the housing.

In the upper part of the body there is a branch pipe for connection to the chimney and a flame arrester located under it, which increases the efficiency of the furnace and reduces the height of the flame inside the chimney. The baffle is located at an angle to the hob. A partition is made on the hob in the inner space of the body, between the baffle and the hob. Making the baffle at an angle and placing a partition on the hob in the inner space of the body on the path of flue gases and flame in the inner space of the body allows you to create several volumes with different cross sections in the space between the hob and the baffle. Due to the difference in the cross-sectional dimensions of the volumes through which the path of the flue gases lies, optimal operating conditions of the furnace are provided: the speed of movement and direction of the flue gases, which increases the heating of the furnace as a whole with an increase in its efficiency, and, consequently, an increase in its energy efficiency.

The walls of the body can include a relief surface that allows evenly separating and directing upward flows of flame and gases inside the furnace, thereby improving the heat capacity of the furnace.

A door with a window for loading fuel and providing the user with the opportunity to observe the combustion process is fixed in the wall of the body.

A heat-resistant cord is fixed along the perimeter of the door, which excludes the ingress of air between the door and the front wall of the oven and ensures its hermetic locking, thereby maintaining the preset combustion mode.

The door has holes with a latch to regulate the air blowing into the combustion chamber, which allows the most accurate dosing of oxygen entering the chamber, thereby smoothly adjusting the combustion mode, including the strength and duration of the flame. The gate valve for regulating the air supply can be made as a gate valve.

Above the door in the wall of the body there are holes with a slide gate valve to regulate the blowing of the door. This design prevents the formation of soot, soot and carbon deposits on the glass, which, having an extremely low coefficient of thermal conductivity, make it difficult to transfer heat from the furnace to the outside.

A hole is made in the base of the body with a grate installed in it, designed to accommodate solid fuel. An ash chamber is located under the grate, where ash formed during fuel combustion is poured through the grate holes.

In order to prevent overheating of the floor, there are legs in the base of the case.

The body of the heating and cooking stove can be made of gray cast iron, a wear-resistant material with high heat transfer, which ensures the durability of the stove.

The claimed solution is illustrated with the help of a figure, which conventionally shows a possible version of the claimed device.

Figure 1 is a sectional view of a heating and cooking oven.

The numbers in figure 1 indicate: 1 - body, 2 - door, 3 - legs, 4 - holes with a latch, 5 - holes with a gate valve, 6 - a hob, 7 - a branch pipe for connecting to a chimney, 8 - a burner, 9 - flame arrester, 10 - grate, 11 - ash chamber.

Further, with reference to the figure, possible versions of the claimed technical solution are explained.

The heating and cooking oven comprises a body formed by walls, a cooking surface in which the burners are made, and a base.

To form a more accurate representation of the technical solution, a hob is understood as a hole made on the hob with rings of different sizes installed in it.

The body of the heating and cooking oven, including the door and legs, can be made of gray cast iron and painted. In an advantageous embodiment, the wall thickness is 10 mm. The inside of the body can be lined with refractory plates.

The side walls of the body can have a convex shape, arcuate vertical ribs and include a relief surface.

In the upper part of the body there is a branch pipe for connection to a chimney, under which a flame arrester is located, in particular, in the form of a rectangular plate, located at an angle to the cooking surface. A partition is made on the hob in the inner space of the body.

A door with a window made of heat-resistant glass is fixed on the wall in the front part of the body. A heat-resistant cord, for example, ceramic, fiberglass or basalt, is fixed in the groove along the perimeter of the door, ensuring its tight locking. Another heat-resistant cord can be attached around the perimeter of the door window.

In the door, mainly in its lower part, there are holes with a slide gate valve to regulate the air blowing into the combustion chamber. Also, holes with a gate valve are made above the door in the wall of the housing to regulate the blowing of the door.

An opening is made in the base of the body with a grate installed in it, under which an ash chamber is located. Legs can be made at the base of the body.

The heating and cooking stove is used as follows.

Solid fuel is placed on the grate through the door into the combustion chamber, where it is burned. The air flow through the grate and the adjustable door damper provides the oxidation reaction of the combustible substances to support the combustion process. Due to the tightness of the combustion chamber, provided by a heat-resistant cord, by regulating the degree of opening of the holes with a damper located in the door, it is possible to accurately control and regulate the oxygen supply and thus increase or decrease the intensity and level of the flame and maintain optimal combustion parameters.

Hot gases formed during the combustion of fuel in the combustion chamber heat the walls of the body and the hob and are removed through the chimney.

The hob with hotplates allows you to use the oven not only for heating the room, but also for heating water and cooking.

During operation, the glass of the door remains clean, due to the presence of holes with a slide gate, made above the door. The incoming air acquires a certain direction of movement downward along the glass, due to which an air curtain appears, which cuts off possible carbon deposits.

Combustion products in the form of ash go through the grate into the ash chamber.

The heating and cooking stove is characterized by high accuracy of oxygen supply regulation and the ability to maintain optimal combustion modes.

A specialist in this field, it is obvious that the given example of a heating and cooking oven and its individual parts, as well as the view shown in the figure, do not limit the scope of the proposed technical solution. It is possible to manufacture and use the furnace in other types within the scope of the claimed formula.
