Description

Technical Field

[0001] This utility model relates to the field of heating appliances, specifically a fire-viewing stove. Background Technology

[0002] A fire-watching stove is a traditional heating device, primarily used for warmth, but also for everyday purposes such as boiling water and cooking. People can gather around the stove to warm themselves and chat while the fire burns, hence the name "fire-watching stove." Traditional fire-watching stoves only support a single fuel, such as firewood, and are incompatible with clean energy sources like alcohol, limiting their application scenarios. Their applicability is greatly reduced when a smoke-free environment and environmental requirements are needed indoors. Furthermore, the flame shape of a fire-watching stove is random and uncontrollable, making it difficult to match the heating needs of different cooking utensils. For example, long-handled pots require strip-shaped flames, while round-bottomed kettles require columnar flames, resulting in low thermal efficiency. Therefore, there is an urgent need to design a fire-watching stove to solve these problems. Utility Model Content

The perforated shelf 9 can also be installed on the top of the protective glass 8, and cooking utensils can be placed on the perforated shelf 9 for heating.

[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the main frame 1 of the fire-watching stove has an ash-collecting box inlet on one side. The ash-collecting box 6 can be detachably installed into the main frame 1 of the fire-watching stove through the ash-collecting box inlet. Ash-collecting box brackets 5 are provided on both sides of the main frame 1 of the fire-watching stove and at the bottom of the ash-collecting box 6. The ash-collecting box brackets 5 are fixedly connected to the main frame 1 of the fire-watching stove. The ash-collecting box 6 is transferred into the main frame 1 of the fire-watching stove through the ash-collecting box inlet and is supported by the ash-collecting box brackets 5 to ensure the stability of the ash-collecting box 6 installation. In addition, the ash-collecting box 6 adopts a drawer-like design, which is convenient for loading and unloading, easy for putting in firewood and taking out ash, and convenient for use.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, at the four corners of the top of the main frame 1 of the fire-watching stove, extension baffles 101 are formed above the base plate 2. A glass baffle 7 is fixedly connected to the top of the base plate 2 at each extension baffle 101. A glass retaining groove is formed between the glass baffle 7 and the extension baffle 101. The bottom end of the protective glass 8 is inserted into two adjacent glass retaining grooves for limiting and fixing. The extension baffle 101 and the glass baffle 7 are used to limit and fix the protective glass 8, so that the protective glass 8 is installed around the top of the main frame 1 of the fire-watching stove. The protective glass 8 is easy to disassemble and assemble, which facilitates the transportation and storage of the fire-watching stove.

[0029] In this embodiment, as Figure 1 and Figure 5As shown, the hollowed-out shelf 9 has bent edges 901 on all four sides facing downwards. The bent edges 901 have slots 902 on both sides for the protective glass 8 to be inserted. The slots 902 on the hollowed-out shelf 9 make it easy to assemble the hollowed-out shelf 9 onto the top of the protective glass 8. In actual application, the slots of the hollowed-out shelf 9 are engaged with the two parallel protective glass 8, and the position can be moved and adjusted on the protective glass 8 to ensure the best heating effect.

[0030] In this embodiment, as Figure 2 As shown, the base plate 2 has multiple ventilation holes to improve ventilation and combustion efficiency.

[0031] In this embodiment, as Figure 6 and Figure 7 As shown, it also includes a long strip alcohol box 10. The top outer side of the long strip alcohol box 10 is provided with a first outer edge overlap. The long strip alcohol box 10 passes through the through port 301. The first outer edge overlap is similar in shape to the mounting port 201. The first outer edge overlap is installed inside the mounting port 201 and overlaps with the base plate 3. An alcohol box combustion plate 1001 is detachably installed at the top of the inside of the long strip alcohol box 10. The long strip alcohol box 10 is used to replace the mounting port cover plate 4. The mounting port cover plate 4 is removed, and the ash collection box 6 is removed from the inside of the main frame 1 of the observation furnace. Then, the long strip alcohol box 10 passes through the mounting port 201 and the through port 301, so that the first outer edge overlap is installed into the mounting port 201 and overlaps with the base plate 3 to complete the fixation. By adding alcohol to the long strip alcohol box 10 for combustion, the flame forms a long strip multi-column flame through the alcohol box combustion plate 1001, providing different fuel supply methods for observation and heating of cooking utensils.

[0032] In this embodiment, as Figure 8 , Figure 9 and Figure 10As shown, it also includes a circular alcohol cylinder 11. The outer side of the top of the circular alcohol cylinder 11 is provided with a second outer edge. The circular alcohol cylinder 11 passes through the through-hole 301. The second outer edge is similar in shape to the mounting opening 201. The second outer edge is installed inside the mounting opening 201 and overlaps the base plate 3. The circular alcohol cylinder 11 has a double-layer design. At the bottom of the outer layer of the circular alcohol cylinder 11, multiple first air inlets 1101 are evenly spaced along the circumference. At the top of the inner layer of the circular alcohol cylinder 11, multiple second air inlets 1102 are evenly spaced along the circumference. The circular alcohol cylinder 11 is used to replace the long strip alcohol box 10 and the mounting opening cover plate 4. The long strip alcohol box 10 or the mounting opening cover plate 4 is removed, and the ash collection box 6 is removed from the inside of the main frame 1 of the observation furnace. Then, the circular alcohol cylinder 11 is passed through the mounting port 201 and the through port 301, so that the second outer edge is installed into the mounting port 201 and overlapped on the base plate 3 to complete the fixation. Alcohol is added into the circular alcohol cylinder 11 for combustion. However, during the combustion process, the outside air enters from the first air inlet 1101, flows inside the circular alcohol cylinder 11 and exits from the second air inlet 1102, forming a spiral upward columnar flame. Compared with the long strip alcohol box 10, it provides a different flame shape to adapt to different cooking utensils. Of course, in other embodiments, the fire-viewing stove of this application is not limited to the two replaceable parts of the long strip alcohol box 10 and the circular alcohol cylinder 11. Replaceable parts that can form other flame shapes can be designed according to needs.

[0033] In this embodiment, the main frame 1 of the observation furnace, the base plate 2, the bottom support plate 3, the mounting port cover plate 4, the ash receiving box bracket 5, the ash receiving box 6, the hollow storage plate 9, the long strip alcohol box 10, and the round alcohol cylinder 11 are all made of metal materials, such as stainless steel and carbon steel.

[0034] Working principle: When using this fire-watching stove, the mounting cover plate 4 is installed into the mounting port 201, and the mounting cover plate 4 is fixed on the base plate 3. The firewood is placed inside the ash collection box 6, and after the firewood is lit, it is installed inside the main frame 1 of the fire-watching stove. The flame extends through the base plate 3 and the base plate 2 to the flame combustion zone formed by the protective glass 8 for heating the surrounding people. The perforated shelf 9 can also be installed on the top of the protective glass 8, and cooking utensils can be placed on the perforated shelf 9 for heating.

[0035] Remove the mounting port cover plate 4 and the ash collection box 6 from the inside of the main frame 1 of the observation furnace. Then, pass the long strip alcohol box 10 through the mounting port 201 and the through port 301, so that the first outer edge is installed into the mounting port 201 and overlapped on the base plate 3 to complete the fixation. Add alcohol to the long strip alcohol box 10 to burn it. The flame forms a long strip multi-column flame through the alcohol box combustion plate 1001, providing different fuel supply methods for observation and cooking appliance heating.

[0036] Remove the mounting port cover 4 and the ash collection box 6 from the main frame 1 of the observation stove. Then, pass the circular alcohol cylinder 11 through the mounting port 201 and the through port 301, so that the second outer edge is installed into the mounting port 201 and overlapped on the base plate 3 to complete the fixation. Add alcohol to the circular alcohol cylinder 11 for combustion. During the combustion process, the outside air enters from the first air inlet 1101, flows inside the circular alcohol cylinder 11 and exits from the second air inlet 1102, forming a spiral upward columnar flame. Compared with the long strip alcohol box 10, it provides a different flame shape to adapt to different cooking utensils, so that the observation stove can be used for various fuels to provide observation and cooking utensils heating, and can provide different flame shapes to adapt to different cooking utensils heating use.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
