Burning device

BACKGROUND OF THE INVENTION The present invention relates to an outdoor device consisting of 5 refractory materials which is elongated. In addition, the unit has a vertical slot, a removable cover made of refractory material and a bottom.

It is known to burn fire outdoors in discrete forms. Fire can be burned 10 outdoors eg. open fires, tar pots, ovens assembled from barbecues, or jack candles.

These previously known ways to burn fire outdoors do not take sufficient account of safety considerations, energy efficiency, environmental cleanliness, post-heat recovery, fire management and maintenance. In addition, weather fluctuations 15 greatly influence the enjoyment of the end result. Smoke hazards in previously known smoking patterns are variable and difficult to control.

The device according to the invention is characterized by a structure made of refractory material which is elongated. The device has an elongated vertical slot 20. The unit has a detachable lid and base made of refractory material and a base.

The device according to the invention has several significant advantages. The oblong structure and the vertical gap allow effective fire burning. 25 Refractory and Charging The building material builds up hard internal heat in the unit, which contributes to efficient combustion. A variety of solid combustible materials can be burned in the unit. Due to its protective structure, ignition of the material to be burned in the unit is easy and the material to be burned is low. It is safe to stay around the unit as some of the walls are protected. Thus, directing the sight of the fire 30 is also easy for those who enjoy the fire. The removable deck construction allows the regulator draft to be adjusted.

In use, the invention provides an easy way to keep an open fire and to enjoy a flame with a small amount of combustible material The ease of ignition and good protection reduces the 35 threshold to enjoy fire. The heat that binds to the refractory mass can also be used to cook food if desired. Ways could be, for example, brewing food, grilling, smoking and even brewing coffee in a soup pan. The unit produces heat, light and joy at all times of the year.

The device of the invention is suitable for all kinds of outdoor spaces where it is desired to entertain 40 and make the environment comfortable with live fire or to cook in a new way. The structure can be made up of modules that allow anyone to build the structure and height that they need, including easy storage, transport and production.

The product of the invention can be sold e.g. hardware stores, department stores, garden stores, gas stations and the web.

The invention is characterized by what is defined in the claims.

The invention will be described in more detail below with reference to the accompanying drawings, in which Figure 5 shows a front / top view of the combustion apparatus according to the invention, Figure 2 shows the same front and rear view, Figure 3 shows the lid of a combustion apparatus; Fig. 7 shows a liquid biofuel combustion unit The combustor body (2) consists of a refractory material, preferably made of rocky or ceramic pulp. Solid stone or metal is also a good material. The product is characterized by elongation, the possible modular structure 15 allowing the determination of a suitable height for each purpose. The longitudinal slot (3) in this example is 5 cm wide, the bottom opening (4) in this example is 12 x 12 cm, the opening sizes may vary depending on the application.

The device includes a base (5) which is also made of refractory material. 20 The sole ensures safe combustion when the mass absorbs heat, so that the device is not exposed to high heat and is easy to clean.

The apparatus comprises a detachable lid part (7) of refractory material and may have a handle for ease of handling. Thanks to the cover section, the fire draft and the desired direction of the fire can be controlled. Thanks to the lid portion, the inside temperature 25 of the device is also raised and maintained at the desired level when the lid is held. The inside temperature of the appliance can be monitored with a thermometer mounted on the frame (2). These allow the appliance to be used for the preparation and cooking of food.

The material to be burned may be e.g. wood-based wood valves of various sizes and shapes, products made of wood-based materials, for example wood pellets. In addition, wood and cardboard-based products or coal made of wood and other materials are suitable as combustible material. Liquid biofuels can be burned with 5 dedicated combustion units (16).

The combustion of fine-grained products takes place in combustion baskets (9), which may be several depending on the length of the structure. The upper basket is placed on a freely adjustable intermediate level (14). The blades on the sides of the intermediate plate (14) press against the wall of the hollow core (6) and stop the intermediate plate (14) at the desired height. The other combustible material-10 materials are burned in the hollow core (6) directly from the bottom (5).

The combustion baskets are inserted into the hollow inner part (6) from the upper part or from the possibly wider lower opening (5).

The material of the device may vary, the most important material requirement being strength, heat resistance and the ability to absorb heat. It is important for operational safety that, although 15 masses allow high heat to be generated inside the product, the mass does not make the outer surface of the product too hot.

Other modifiable features of the device include the ability to manufacture devices for various purposes, wherein the size of the longitudinal aperture (3), the lower aperture (4) and the hollow core (6) varies, so that the fire appearance and fire rate can be controlled.

The possible modular structure (10) of the frame (2) allows a structure of different heights to be used. The modular design also facilitates transportation and storage. The module (10) may also be provided with a window (12) or aperture (11) from walls other than the slot, thus providing light coming in many directions.

25 The elongated design and shape of the device may vary according to space and situation.

Viewed from above, the shape can be a triangle, an oval, a circle, a square, or some other irregular shape. Multiple devices are stacked against each other to create an impressive array of devices with fire and light in many directions. It is also possible to construct a device having more than one hollow core (6) in the same device.

The device can also be coated with various refractory materials for the environment or for different applications, such as ceramic tiles, coatings imitating the nature of wood bark, trunk, or stone.

Various embodiments of the invention have been described above. The invention also has a variety of cooking embodiments, some of which are exemplified herein.

The appliance also has cooking facilities. After the combustion event, the hollow core (6) generates a large amount of internal heat, which can be controlled by the device lid 5 (7), which can be utilized e.g. A great way is to bake, prepare or smoke food in the cooking unit (13) inside the hollow (6) after the burning event.

Roasting of the sausage runs smoothly in the hollow inside of the appliance (6) after the burn event, since the heat in the appliance is long when the appliance lid (7) is closed.

10 Heat from the hollow core (6), during and after a fire, can be used to roast, grill, grill, brew, stew, flatten or brew coffee in a soup pan. Cooking can take place directly from the hollow core (6) over the heat of the flood or over the grate (15) placed on the burner.

The invention may have other embodiments which may vary within the scope of the claims.
