[0002] A heating and cooking stove is a device that integrates heating and cooking functions, typically used in homes, camping, or other situations requiring simultaneous heating and cooking. However, in practical use, similar dual-purpose stoves have several drawbacks. For example, during operation, frequent manual refueling is required, necessitating the use of one person, making single-person operation inconvenient. Furthermore, precise control of the amount added during manual refueling is difficult, easily leading to over- or under-addition of fuel, causing inconsistent heat levels and affecting cooking results. Additionally, it lacks the function of using waste heat to boil water; hot water needs to be boiled separately during cooking, increasing preparation time and reducing efficiency. Therefore, we designed a biomass heating and cooking dual-purpose stove to address these issues. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This embodiment proposes a biomass heating and cooking dual-purpose stove, including a stove body 1, a combustion mechanism 2 and a storage mechanism 3 arranged in front and back within the stove body 1. The stove body 1 is the protection mechanism of the dual-purpose stove, ensuring the safety of the dual-purpose stove during operation. The combustion mechanism 2 is the combustion and heat release mechanism of biomass fuel. Heating and cooking can be carried out by the combustion of biomass in the combustion mechanism 2. The storage mechanism 3 is the storage and placement mechanism of biomass fuel. Fuel can be automatically added to the combustion mechanism 2 by the storage mechanism 3.

[0027] Specifically, the combustion mechanism 2 includes a combustion chamber 201. A filling layer 5 is fixedly installed on the upper part of the combustion chamber 201. A furnace liner 202 is fixedly installed in the center of the filling layer 5. A frame plate 206 is fixedly installed inside the furnace liner 202. Multiple sets of heat-conducting plates 203 extending to the outside of the furnace body 1 are fixedly installed on the front and both sides of the filling layer 5. One end of each heat-conducting plate 203 is in contact with the outer wall of the furnace liner 202. A water-heating inner tank 503 is fixedly installed on the rear side of the filling layer 5. A water-filling pipe 501 extending to the outside of the furnace body 1 is fixedly installed on the upper side of one side of the water-heating inner tank 503. A drain valve 502 extending to the outside of the furnace body 1 is fixedly installed on the lower side of one side of the water-heating inner tank 503.

[0028] The storage mechanism 3 includes a storage cavity 301, a lifting plate 304 is slidably installed inside the storage cavity 301, a drive plate 307 extending to the outside of the furnace body 1 is fixedly installed on the back of the lifting plate 304, a lifting motor 305 is fixedly installed at the bottom of the back of the furnace body 1, a threaded rod 306 that is threadedly connected to the drive plate 307 is fixedly installed at the output end of the lifting motor 305, and a feeding channel 207 that communicates with the storage cavity 301 is opened on the upper back of the furnace liner 202.

[0029] During operation, the filling layer 5 can fix the furnace 202 inside the combustion chamber 201. The rack 206 installed inside the furnace 202 can support the biomass fuel, facilitating the combustion and heat release of the biomass fuel in the furnace 202. The heat generated when the fuel burns inside the furnace 202 can be used for heating. The heat conduction plate 203 can conduct the heat generated when the furnace 202 is in operation to the outside of the furnace body 1. The heating efficiency of the dual-purpose stove is improved by the heat conduction plate 203. Furthermore, cookware can be placed on top of the furnace 202 for cooking. The inner liner 503 installed inside the filling layer 5 can be filled with water through the water inlet pipe 501. The residual heat of the furnace 202 during operation can heat the water in the inner liner 503, thus realizing the function of recovering residual heat during the operation of the dual-purpose stove. The drain valve 502 can drain the hot water after boiling in the furnace 202, making it convenient for personnel to use hot water during cooking. The storage cavity 301 can store biomass fuel. The threaded rod 306 is threadedly connected to the drive plate 307 on the back of the lifting plate 304. The drive plate 307 and the lifting plate 304 can be raised and lowered by the lifting motor 305 driving the threaded rod 306. When the lifting plate 304 is raised, it can lift the biomass fuel in the storage cavity 301. The lifted biomass fuel can enter the interior of the furnace 202 through the feeding channel 207, thus realizing the function of automatic filling during the operation of the dual-purpose stove, avoiding the need for manual filling by staff, which increases manpower and improves the convenience of cooking when using the dual-purpose stove by a single person.

[0030] Furthermore, a cover plate 4 is provided on the front side of the top of the furnace body 1 to cooperate with the furnace liner 202. Multiple sets of through holes 401 are opened on the outer side of the top surface of the cover plate 4, and a lifting lug 402 is fixedly installed at the center of the top of the cover plate 4. The cover plate 4 can close the top of the furnace liner 202 when the dual-purpose furnace is heating, which avoids the possibility of fire caused by the flame when the biomass fuel is burning in the furnace liner 202, thus increasing the safety of the dual-purpose furnace during heating operations. The through holes 401 can be used for ventilation when the cover plate 4 is closed to the top of the furnace liner 202, ensuring that the biomass fuel is fully burned and heats evenly in the furnace liner 202. The lifting lug 402 makes it easy for personnel to place and remove the cover plate 4 with the help of appropriate tools.

[0031] A pusher motor 302 is fixedly installed on the upper back of the furnace body 1. The output end of the pusher motor 302 extends into the storage cavity 301 and is fixedly installed with a pusher auger 303. One end of the pusher auger 303 extends into the feeding channel 207. The pusher motor 302 drives the pusher auger 303 to rotate in the storage cavity 301 and the feeding channel 207. The pusher auger 303 can evenly and equally discharge biomass raw materials into the furnace liner 202, ensuring the uniformity of automatic feeding of the furnace body and improving the combustion quality of the flame when the dual-purpose furnace is in use.

[0032] A level gauge 504 extending to the outside of the furnace body 1 is fixedly installed on the other side of the inner water tank 503. The level gauge 504 can measure the water level in the inner water tank 503, making it convenient for personnel to know the water level in the inner water tank 503.

[0033] A flue pipe 204 is fixedly installed on one side of the furnace body 1. One end of the flue pipe 204 extends into the interior of the furnace chamber 202. A mesh plate 205 is fixedly installed on one end of the flue pipe 204. The flue pipe 204 can discharge the smoke and harmful substances generated during the operation of the dual-purpose furnace, thus preventing people from being poisoned when using the dual-purpose furnace for heating. The mesh plate 205 can block the flame, preventing the flame from entering the flue pipe 204 and causing heat loss.

[0034] An ash removal door 102 is movably installed on the lower front of the furnace body 1, and a closing plate 103 is movably installed on the top of the storage chamber 301. Both the ash removal door 102 and the closing plate 103 have grooves on their surfaces. The ash produced when biomass fuel burns in the furnace chamber 202 falls into the bottom of the combustion chamber 201 through the gaps in the support plate 206. Personnel can clean the ash by opening the ash removal door 102. The closing plate 103 can close and protect the top of the storage chamber 301, preventing sparks from the furnace chamber 202 from falling into the storage chamber 301 and causing a fire, and preventing water from cooking from wetting the biomass fuel. The grooves facilitate the operation of opening the ash removal door 102 and the closing plate 103.

[0035] In addition, a base 101 is fixedly installed at the bottom of the furnace body 1. The base 101 can support the bottom of the furnace body 1 and isolate the furnace body 1 from the ground, thus preventing water on the ground from corroding the furnace body 1.
