Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a wood-fired stove. Background Technology

[0002] A wood-fired stove is a cooking appliance that uses firewood as its raw material for heating. It typically has a combustion chamber with openings at the top and bottom. At the bottom of the combustion chamber is a furnace bridge to support the firewood, which has numerous oxygen supply holes to allow ventilation during combustion. However, due to the high density and large volume of firewood, incomplete combustion is common, resulting in low energy utilization. This not only leads to firewood waste but also environmental pollution. Furthermore, incomplete combustion produces a large amount of unburned ash, which can clog the oxygen supply holes on the furnace bridge, further hindering oxygen supply for subsequent firewood combustion and severely impacting the normal operation of the wood-fired stove. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wood-fired stove that can improve the energy utilization rate of firewood and reduce the risk of clogging of the oxygen supply hole.

[0004] A wood-fired stove according to a first aspect embodiment of the present invention includes: a stove body having an independent combustion chamber and a first air intake chamber, the combustion chamber being open at its upper end, and a feeding channel extending through the periphery of the combustion chamber and communicating with the combustion chamber through a side wall of the stove body, the first air intake chamber being located below the combustion chamber; a blower being disposed on one side of the stove body, the air outlet of the blower being communicating with the first air intake chamber; and a furnace bridge being disposed at the bottom of the combustion chamber, the furnace bridge having ash collection holes and oxygen supply holes, the number of oxygen supply holes being multiple, the oxygen supply holes being spaced apart and distributed around the ash collection holes, each oxygen supply hole communicating with the combustion chamber and the first air intake chamber, and the cross-sectional area of ​​each oxygen supply hole being smaller than the cross-sectional area of ​​the ash collection hole; wherein, the lower part of the stove body has an ash collection space, and the stove body is also provided with an ash collection channel communicating with the ash collection holes and the ash collection space, the ash collection channel extending vertically through the first air intake chamber and being isolated from the first air intake chamber.

[0023] Reference Figures 1 to 9This utility model provides a wood-fired stove, including a stove body 100, a blower 200, and a stove bridge 300. The stove body 100 has an independent combustion chamber 110 and a first air intake chamber 120. The upper end of the combustion chamber 110 is open. A feeding channel 130 is formed in the side wall of the stove body 100, penetrating the periphery of the combustion chamber 110 and extending to communicate with the combustion chamber 110. The first air intake chamber 120 is located below the combustion chamber 110. The blower 200 is located on one side of the stove body 100, and the air outlet of the blower 200 is connected to the first air intake chamber 120. The stove bridge 300 is located at the bottom of the combustion chamber 110. The furnace body 100 has ash collection holes 310 and oxygen supply holes 320. There are multiple oxygen supply holes 320, which are arranged at intervals around the ash collection holes 310. Each oxygen supply hole 320 is connected to the combustion chamber 110 and the first air intake chamber 120, and the cross-sectional area of ​​each oxygen supply hole 320 is smaller than that of the ash collection hole 310. The furnace body 100 has an ash collection space 140 at the bottom. The furnace body 100 is also provided with an ash collection channel 330 that connects the ash collection holes 310 and the ash collection space 140. The ash collection channel 330 runs through the first air intake chamber 120 in the vertical direction and is isolated from the first air intake chamber 120.

[0024] In the wood-fired stove of this utility model embodiment, firewood is placed into the combustion chamber 110 through the feeding channel 130 during use. By opening ash collection holes 310 and multiple oxygen supply holes 320 on the furnace bridge 300, the oxygen supply holes 320 connect the first air intake chamber 120 and the combustion chamber 110. This allows the air input at high speed from the blower 200 into the first air intake chamber 120 to be sprayed upwards into the combustion chamber 110 through each oxygen supply hole 320. Since each oxygen supply hole 320 is distributed at intervals around the ash collection holes 310, the air entering from each oxygen supply hole 320 can be evenly distributed in the combustion chamber 110. This can improve the combustion efficiency of the firewood in the combustion chamber 110, making the firewood in the combustion chamber 110 burn more completely, which is beneficial to improving the energy utilization rate of the firewood. Furthermore, since the cross-sectional area of ​​each oxygen supply hole 320 is smaller than that of the ash collection hole 310, there is an ash collection space 140 below the furnace body 100. The furnace body 100 is also provided with an ash collection channel 330 connecting the ash collection hole 310 and the ash collection space 140, so that the ash produced after the firewood is burned can fall directly into the ash collection space 140 through the ash collection hole 310 and the ash collection channel 330. The independent ash collection hole 310 on the furnace bridge 300 can facilitate the discharge of ash in the combustion chamber 110, reduce the risk of blockage of the oxygen supply hole 320, and thus ensure the normal input of subsequent air, which is conducive to improving the combustion efficiency of subsequent firewood and ensuring the normal use of the wood-burning stove.

[0025] Reference Figure 5In some embodiments, the ash discharge hole 310 is a strip-shaped through hole extending toward the feed channel 130, thereby facilitating the downward discharge of ash through the ash discharge hole 310. It is understood that the ash discharge hole 310 can be a strip-shaped through hole structure, or it can be a circular through hole or other through hole shapes, and this utility model does not specifically limit it in this regard.

[0026] Reference Figures 1 to 8 In some embodiments, the furnace body 100 has a second air intake chamber 150 surrounding the combustion chamber 110 and the first air intake chamber 120. The bottom wall of the second air intake chamber 150 has a first air intake hole 151, and the outlet of the blower 200 is connected to the first air intake hole 151. The peripheral wall of the first air intake chamber 120 has multiple second air intake holes 121 connected to the second air intake chamber 150, and all the second air intake holes 121 are arranged sequentially at intervals along the peripheral wall of the first air intake chamber 120. Thus, the blower 200 introduces external air at high speed into the second air intake chamber 150 through the first air intake hole 151. The air entering the second air intake chamber 150 then flows back into the first air intake chamber 120 through each of the second air intake holes 121, and is then sprayed upwards into the combustion chamber 110 through each of the oxygen supply holes 320 to provide oxygen for the combustion of the firewood.

[0027] Reference Figure 6 and Figure 7 In some embodiments, the peripheral wall of the combustion chamber 110 is provided with a plurality of third air inlets 111 that communicate with the second air inlet chamber 150. All the third air inlets 111 are arranged sequentially at intervals along the circumference of the combustion chamber 110 and located above the feed channel 130. Therefore, part of the air entering the second air intake chamber 150 flows into the first air intake chamber 120 through the second air intake hole 121 and upwards into the combustion chamber 110 through the oxygen supply hole 320 to provide oxygen for the combustion of firewood in the combustion chamber 110. The other part of the air continues to flow upwards along the second air intake chamber 150 to the third air intake hole 111, and then flows into the combustion chamber 110 through the third air intake hole 111, where it flows from top to bottom. This pushes the residue from incomplete combustion of firewood and the generated carbon monoxide and other gases down to the bottom of the combustion chamber 110 for continued combustion, preventing the carbon monoxide and other gases from being directly discharged outdoors and polluting the air. This further makes the combustion of firewood more complete and helps improve the energy utilization rate of firewood. Reference Figures 1 to 9In some embodiments, a cookware support portion 152 is provided at the upper end of the second air intake chamber 150, surrounding the outer periphery of the combustion chamber 110. The cookware support portion 152 is connected between the outer peripheral wall of the combustion chamber 110 and the inner peripheral wall of the second air intake chamber 150, and is located above all the third air intake holes 111. The upper surface of the cookware support portion 152 is a support surface extending radially upward from the inside to the outside of the combustion chamber 110. This support surface can adapt to the bottom wall of the cookware to provide stable support for the cookware. Thus, the heat generated by the burning of firewood in the combustion chamber 110 can be directly transferred upward to the cookware, thereby heating the cookware. The cookware support portion 152 is located above all the third air intake holes 111, so that the air flowing into the third air intake holes 111 from the second air intake chamber 150 can completely enter the combustion chamber 110 below the cookware, preventing the air flowing into the third air intake holes 111 from flowing upward to other places.

[0028] Reference Figure 6 and Figure 7 In some embodiments, a baffle 153 is provided in the second air intake chamber 150 above the first air intake hole 151. The baffle 153 is spaced apart from the bottom wall of the second air intake chamber 150 and extends radially along the first air intake chamber 120 to the upper end of one of the first air intake holes 151. Thus, under the obstruction of the baffle 153, most of the air flowing into the second air intake chamber 150 through the first air intake hole 151 can be diverted to flow into the first air intake chamber 120 through the second air intake hole 121, and a small portion flows upward to the third air intake hole 111 and flows into the combustion chamber 110 through the third air intake hole 111.

[0029] Reference Figures 2 to 9 In some embodiments, the furnace body 100 has an exhaust chamber 160 surrounding the second air inlet chamber 150. The furnace body 100 also has a smoke exhaust channel 170 communicating with the exhaust chamber 160. The inner peripheral wall of the exhaust chamber 160 has a plurality of first air outlets 161 communicating with the combustion chamber 110. All the first air outlets 161 are arranged sequentially at intervals along the circumference of the combustion chamber 110. Thus, the smoke generated by the combustion of firewood in the combustion chamber 110 can flow upward through each of the first air outlets 161 into the exhaust chamber 160, and then be discharged outward from the smoke exhaust channel 170.

[0030] Reference Figures 2 to 8In some embodiments, a heat insulation cavity is further provided between the second air intake cavity 150 and the exhaust cavity 160. The upper end of the heat insulation cavity is open, and the heat insulation cavity is filled with a heat insulation layer 181. The heat insulation layer 181 can insulate the combustion cavity 110, preventing a large amount of heat from dissipating outward from the combustion cavity 110, thereby improving the energy utilization rate of the firewood in the combustion cavity 110. The first air outlet 161 is located above the heat insulation layer 181 and is connected to the upper end of the combustion cavity 110 through the heat insulation cavity. Thus, the smoke generated by the combustion of firewood in the combustion cavity 110 can flow upward, flow outward through the heat insulation cavity to the first air outlet 161, and then into the exhaust cavity 160.

[0031] Reference Figures 2 to 9 In some embodiments, the exhaust duct 170 is located outside the furnace body 100 and below the second air inlet chamber 150 and the exhaust chamber 160. The bottom wall of the exhaust chamber 160 is provided with a plurality of second air outlets 162 that communicate with the exhaust duct 170. All the second air outlets 162 are arranged sequentially at intervals along the circumference of the exhaust chamber 160. The blower 200 is installed below the exhaust duct 170. A first air inlet duct 171 is provided between the blower 200 and the bottom wall of the second air inlet chamber 150. The first air inlet duct 171 penetrates the exhaust duct 170 in the vertical direction and is isolated from the exhaust duct 170. The lower end of the first air inlet duct 171 is connected to the air outlet of the blower 200, and the upper end of the first air inlet duct 171 is connected to the first air inlet 151.

[0032] By adopting the above structure, the blower 200 can draw outside air upwards through the first air intake channel 171 into the second air intake chamber 150, and then through the second air intake chamber 150 into the combustion chamber 110 to provide oxygen for the combustion of firewood. The smoke discharged from the exhaust chamber 160 can flow through each of the second air outlets 162 into the smoke exhaust channel 170 and be discharged outwards through the smoke exhaust channel 170.

[0033] Reference Figures 2 to 9 The smoke exhaust duct 170 has a smoke exhaust outlet at one end. A guide plate 172 is installed inside the smoke exhaust duct 170. The guide plate 172 is connected between the inner wall of the smoke exhaust duct 170 and the outer peripheral wall of the first air intake duct 171, and the guide plate 172 extends upward from the bottom wall of the smoke exhaust duct 170 along the direction close to the smoke exhaust outlet. Thus, the guide plate 172 can guide the smoke flowing out of the second air outlet 162 to be quickly discharged towards the outlet of the smoke exhaust duct 170.

[0034] Reference Figures 2 to 7In some embodiments, an ignition needle 400 and a gas nozzle 410 for delivering gas are installed in the ash collection space 140. In the horizontal direction, the ignition needle 400 is installed on the side of the ash collection channel 330 near the feed channel 130 and extends toward the ash collection channel 330. The ignition needle 400 is staggered with the ash collection channel 330 in the horizontal direction. The gas nozzle 410 is installed below the ignition needle 400 and is arranged toward the ignition needle 400. An ash baffle 420 is also provided above the ignition needle 400. A second air intake channel 190 is also provided in the ash collection space 140. The second air intake channel 190 is located outside the first air intake channel 171 and extends from bottom to top toward the ignition needle 400. The lower end of the second air intake channel 190 penetrates the side wall of the first air intake channel 171 and is connected to the first air intake channel 171. Therefore, the gas nozzle 410 can spray gas towards the ignition needle 400, and the second air intake channel 190 can supply air towards the ignition needle 400. The ignition needle 400 can then quickly ignite the gas sprayed from the gas nozzle 410 to form a flame. The flame can flow upward through the ash collection channel 330 and ash collection hole 310 into the combustion chamber 110 to ignite the firewood inside. This facilitates the ignition of the firewood in the combustion chamber 110 when the wood-burning stove is first used. In addition, by setting an ash baffle 420 above the ignition needle 400, ash 3 falling from the ash collection channel 330 can be prevented from falling onto the ignition needle 400 or the gas nozzle 410, thus affecting the normal use of the ignition needle 400 and the gas nozzle 410, which helps to protect the ignition needle 400 and the gas nozzle 410.

[0035] Understandably, in the actual use of a wood-fired stove, the firewood in the combustion chamber 110 can be ignited first through the above structure. After the firewood has burned stably, the gas nozzle 410 and the ignition needle 400 can be closed. This makes it convenient to ignite the firewood while also saving gas.

[0036] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
