Description

[Technical field]

[0001] The present invention relates to a solid fuel heating device for heating mobile structures with the option of cooking hot food. [Background technology]

[0002] The prior art teaches a furnace for a mobile structure with a movable shutter and a spark arrester, comprising a housing including a combustion chamber with a door, a fire grate, an ashtray with an ash drawer, a chimney, a protective casing convector and a support, the combustion chamber includes a damper with an option to move the combustion chamber, and further comprising a spark arrester adjacent to the combustion chamber, the spark arrester consisting of a cavity and a chimney tube immersed in the cavity. [Patent Document 1: Russian Patent Application Publication No. 145329, Publication Date September 20, 2014]

[0003] The closest analogy to the claimed invention is a mobile furnace with a convertible convector shell. The furnace comprises a housing in the form of a hexagonal prism, and the side screens are made so that their position relative to the side walls of the housing can be changed by rotating the lower hinges.

[0004] [Patent Document 1] Russian Patent Application Publication No. 145329 [Patent Document 2] Russian Design Application Publication No. 98663 Summary of the Invention [Problem to be solved by the invention]

[0005] The main problem with the known technical solutions is that they do not have a cooking surface in the same oven.

[0006] The technical problem to be solved in the present invention is to provide a stove which operates in combination with the use of masonry and its use as a cooking surface.

[0007] The technical result is to expand the field of application of the furnace while maintaining its volume in a transportable form. [Means for solving the problem]

[0008] The essence of the claimed device is as follows:

[0009] The furnace with cooking surface comprises a housing with an opening for a chimney and a support, in which there is a combustion chamber with a door, a fire grate, an ashtray and a chimney. Unlike the closest prior art, the furnace housing is equipped with side screens. The front and rear walls of the housing are equipped with oblique grooves for changing the position of the screens, while the screens are provided with rods that move in the grooves.

[0010] In one embodiment, the ash drawer is equipped with a drawer and the furnace is equipped with a built-in spark arrestor that prevents sparks from escaping the housing. Optionally, the spark arrestor is made in the form of a vertical partition in the furnace housing that separates the space between the chimney opening and the air circulation slot.

[0011] In one embodiment, the chimney may be made in one piece, or in another embodiment, it may be modular in the form of multiple segments, which reduces the volume of the furnace during shipping and allows the segments to be assembled based on the condensate generated in the chimney, allowing the condensate to flow down without penetrating the joints between the segments.

[0012] Optionally, the screen is equipped with additional air circulation openings, which perform a protective function and generate convection currents along the furnace housing, accelerating the heating process of the mobile home or other structure.

[0013] In one embodiment, the grooves for changing the position of the screens are made straight with openings at the ends that fix the position, or alternatively made in the shape of a circular arc. This design allows the position of the screens to be reliably changed in the direction upwards from the furnace housing. When the screens are extended, they form a side wall that protrudes above the upper (top) surface of the furnace housing. In this embodiment, masonry is used. When the oven operates with the screens in the folded position, the upper surface can be used as a cooking surface for cookware of any size. Furthermore, to regulate the intensity of the heating process, the furnace can be used in a mode in which only one of the screens is extended.

[0014] The furnace is transported in the folded position of the screen, which significantly reduces the volume of the stove, while in the extended position of the screen, the furnace can be used together with the masonry not only for cooking surface use, but also for heating mobile homes and other structures such as tents and mobile baths. Since the above essential configurations are novel and ensure the achievement of the claimed technical result, it can be concluded that the claimed invention meets the criteria for novelty patentability.

[Diagram 3] FIG. 1 is a front view of the furnace with one screen in the extended position. [Figure 4] FIG. 3 / 4 view of furnace with screen in extended position. [Diagram 5] FIG. 3 / 4 view of furnace with screen in folded position. [Figure 6] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] The principles of the claimed invention are illustrated in the following drawings.

[0017] The heating furnace with hob comprises a housing 1 with a chimney opening 14, a support 2 and a side screen 3, in which there is a combustion chamber 4 with a door 5, a fire grate 6, an ashtray 7 with a drawer 8, a modular chimney 9 and a spark arrestor partition 10. The front wall 11 and the rear wall (not shown) of the housing 1 are provided with an oblique groove 12 for changing the position of the screen 3, which is provided with a rod (not shown) moving in the groove 12 and with openings 13 for air circulation.

[0018] The operating principle of the claimed invention is as follows.

[0019] The furnace is installed on a support 2 and has a modular chimney 9, fuel is loaded into the combustion chamber 4 through a door 5 on the grate 6. When the furnace is used for heating, the screens 3 are stretched by moving along the grooves 13, thus creating convection currents along the furnace housing, on whose upper surface the masonry is located, bricks or stones being fixed in place by the protruding parts of the screens 3. When the furnace is used for cooking, the screens are moved to form a plane on the top surface, on which cooking utensils are placed. If it is necessary to reduce the intensity of the heating process, only one of the screens 3 is used.
