[0002] The stove kang is a combination of'stove' and 'kang'. Some technical solutions about stove kang have appeared in the prior art, such as a household layer combustion gasification carbonization stove kang device disclosed in a Chinese patent with application number 2018220704735, which comprises a gasification chamber, a carbonization chamber and a dirt collection chamber arranged below in the stove body. The lower part of the stove body is provided with a gasification chamber, a carbonization chamber and a dirt collection chamber. The stove body is provided with a furnace cover on the top and a fire barrier ring on the side. The gasification chamber, carbonization chamber and dirt collection chamber are separated by low-density grate and high-density grate from top to bottom; the structure is simple, the cost is low, and the operation, use and maintenance are fast. It is used for single-family use, water heating, fire heating and cooking. However, in the prior art, fuel is added into the stove body through the feeding port, then the fuel is ignited, the charcoal falls into the carbonization chamber, the charcoal burns and produces carbon monoxide and carbon dioxide, the carbon monoxide enters the gasification chamber and is ignited to heat the air in the stove body. However, the carbon monoxide generation efficiency in the carbonization chamber is low in the prior art, which causes the charcoal to be unable to burn quickly, and the utilization rate of fuel is low. Therefore, the present application provides a new household layer combustion gasification carbonization stove kang device. SUMMARY

[0003] In order to make up for the shortcomings of the prior art and solve the problem that in the prior art, fuel is added into the stove body through the feeding port, then the fuel is ignited, the charcoal falls into the carbonization chamber, the charcoal burns and produces carbon monoxide and carbon dioxide, the carbon monoxide enters the gasification chamber and is ignited to heat the air in the stove body, but the carbon monoxide generation efficiency in the carbonization chamber is low in the prior art, which causes the charcoal to be unable to burn quickly, and the utilization rate of fuel is low, the present application provides a household layer combustion gasification carbonization stove kang device.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: The household gas-fired carbonization stove and kang device of this invention includes a kang body; a stove body is provided on one side of the kang body, and a flue is provided on the other side; a base is provided at the bottom of the kang body, and a flue is provided between the base and the kang body; one side of the flue is connected to the flue, and the other side is connected to the stove body; an outer wall is provided on the side of the kang body near the flue, and a partition wall is provided on the other side; a feed inlet is provided on the side of the stove body away from the kang body, and a furnace cover is provided on the top of the stove body; the stove body is provided with, from bottom to top, the following components: The furnace has a No. 1 grate and a No. 2 grate, which divide the furnace body from top to bottom into a gasification chamber, a carbonization chamber, and a slag chamber. The carbonization chamber is connected to the feed inlet. The gasification chamber is connected to the flue through an exhaust port. The bottom of the No. 2 grate has an air inlet pipe that is connected to the outside atmosphere. A water tank is located near the furnace cover inside the furnace body. The top of the water tank has a water inlet pipe with a one-way valve inside. The top of the water tank is connected to an exhaust pipe. A set of jet pipes is evenly distributed around the circumference of the air inlet pipe. The jet pipes pass through the No. 1 grate. The pipe is connected to the exhaust pipe. In the existing technology, fuel is added to the stove body through the feed port and then ignited, causing charcoal to fall into the carbonization chamber. The charcoal burns and produces carbon monoxide and carbon dioxide. The carbon monoxide enters the gasification chamber and is ignited, heating the air in the stove body. However, the carbon monoxide generation efficiency in the carbonization chamber is low in the existing technology, resulting in the charcoal not burning quickly and the fuel utilization rate is low. At this time, a water tank is set in the stove body. The heat from the combustion in the stove body heats the water tank. After the water in the tank boils, it produces water vapor. The water vapor passes through the exhaust pipe and the No. 1 pipe and then enters the jet pipe, and then enters the air inlet pipe. The water vapor mixes with the air and enters the carbonization chamber, causing the high-temperature charcoal to react with the water vapor to produce carbon monoxide, thereby increasing the efficiency of carbon monoxide production from the charcoal. This further increases the combustion efficiency of combustible gases in the gasification chamber and further increases the heating efficiency of the stove body. The heated air in the stove body is then filled into the flue through the smoke exhaust hole to heat the kang body and ensure that the kang body is at a suitable temperature.

[0005] Preferably, the side of the jet pipe closest to the center of the air inlet pipe is inclined upwards; an L-shaped bracket is fixedly connected to the bottom of one end of the jet pipe inside the air inlet pipe, and a cover plate is hinged to the end of the bracket away from the jet pipe, with a tension spring fixed between the cover plate and the bracket; the tension spring drives the cover plate to press and seal the jet pipe, reducing the amount of ash produced by charcoal combustion entering the jet pipe and clogging it, thereby further increasing the reaction efficiency of water vapor and charcoal. At the same time, the jet pipe inclined upwards on the side closest to the center of the air inlet pipe allows the high-speed water vapor ejected from the jet pipe to accelerate the airflow in the air inlet pipe, thereby further increasing the oxygen supply in the stove body, increasing the combustion efficiency of combustible materials, and further increasing the heating efficiency of the stove body.

[0006] Preferably, a second pipe is fixedly connected to the bottom of the water tank, and a first pipe is sleeved inside the second pipe and slidably sealed to it. A rotating cavity is provided in the middle of the first pipe, and a first shaft is provided inside the rotating cavity. One end of the first shaft passes through the rotating cavity and extends to the outside of the rotating cavity. The first shaft is rotatably sealed to the rotating cavity. A water wheel is fixedly connected to one end of the first shaft inside the rotating cavity, and a gear is fixedly connected to the other end. A rack is fixedly connected to the bottom of the water tank at a position corresponding to the gear, and the rack meshes with the gear. The top of the water tank is fixedly connected to the stove body via a spring. When fuel is added to the stove body and ignited, the combustion efficiency of the fuel is low due to the low temperature inside the stove body. At this time, when the water tank is pulled by the spring, the stove... The higher position of the stove body reduces the absorption of heat from fuel combustion by the water tank, allowing the stove body to heat up quickly and reach the appropriate combustion temperature. As the temperature inside the stove body rises, the fuel burns fully and releases heat. At this time, the temperature in the water tank gradually rises. After the water in the tank boils, steam is ejected from the jet pipe through pipes one and two. The steam drives the water wheel to rotate, which in turn drives shaft one and the gear to rotate, causing the water tank to move downwards. This reduces the distance between the flame and the water tank inside the stove body, increases the heating efficiency of the water tank, further increases the rate of steam generation, and thus increases the efficiency of carbon monoxide generation, further increasing the heating efficiency of the stove body.

[0007] Preferably, the water tank is rotatably connected to an annular flexible shaft via a bracket, with a set of bristles evenly distributed around the circumference of the flexible shaft. A first bevel gear is fixedly connected to the flexible shaft, and a second shaft is provided on the water tank at a position corresponding to the first bevel gear. The second shaft passes through the water tank and is rotatably and sealingly connected to the water tank. A second bevel gear is fixedly connected to the end of the second shaft near the first bevel gear, and the second bevel gear meshes with the first bevel gear. A first rotating wheel is fixedly connected to the end of the second shaft away from the first bevel gear, and a second rotating wheel is fixedly connected to the first shaft at a position corresponding to the first rotating wheel. A flexible steel belt is sleeved between the first and second rotating wheels. When the first shaft rotates, it drives the second rotating wheel, which in turn drives the first rotating wheel to rotate via the steel belt. This causes the second shaft to drive the flexible shaft to rotate via the second and first bevel gears, ultimately causing the bristles to rotate and clean the inner wall of the water tank, reducing the adhesion and accumulation of scale on the inner wall of the water tank, thereby increasing the heat transfer efficiency of the water tank, further increasing the steam generation efficiency, and increasing the heating efficiency of the stove.

[0008] Preferably, a flap is hinged to the smoke vent via a pivot pin, and a torsion spring for assisting the flap's reset is fitted on the pivot pin; a sliding column is slidably connected in a groove at the bottom of the smoke vent, and a reset spring is provided between the sliding column and the side wall of the groove; a wedge block is fixedly connected to the other end of the sliding column; a push plate is fixedly connected to the sliding column on the side of the flap closer to the water tank; a wedge block is fixedly connected to the end of the sliding column closer to the second pipe; a support rod is fixedly connected to the side of the second pipe at a position corresponding to the wedge block, and the support rod is slidably connected to the wedge block; when the support rod moves downward, it pushes the sliding column to slide away from the second pipe; when the water tank moves downward... During movement, the support rod is driven by the No. 2 pipe, which in turn pushes the wedge block to slide. The wedge block drives the push plate to move via the sliding column, which in turn drives the flip plate to rotate and increases the ventilation efficiency of the smoke exhaust hole. This results in a lower ventilation efficiency of the smoke exhaust hole when the stove is ignited, accelerating the accumulation of heat inside the stove and increasing the efficiency of the fuel reaching the optimal combustion temperature, thus increasing the combustion efficiency of the fuel. When the temperature inside the stove rises, the push plate moves and drives the flip plate to rotate, increasing the ventilation efficiency of the smoke exhaust hole, which in turn allows more oxygen to enter the stove to participate in combustion, further increasing the heating efficiency of the stove.

[0009] Preferably, the top of the flue is provided with a set of horizontally placed U-shaped pipes, the upper part of which is embedded inside the stove body and connected to the water tank through a flexible hose; the other end of the U-shaped pipe is connected to the water tank through a water pipe and a circulation pump; through the connection between the U-shaped pipe and the water tank, and by continuously increasing the circulation speed of the hot water in the water tank through the circulation pump, the heat storage capacity of the stove body is increased, the heating uniformity of the stove body is further increased, and the heat preservation effect of the stove body is increased.

[0010] The beneficial effects of this invention are as follows:

[0011] 1. The household gasification and carbonization stove and kang device of the present invention heats the water tank by the heat of combustion in the stove body. After the water in the tank boils, it produces water vapor. The water vapor passes through the exhaust pipe and the No. 1 pipe and then enters the jet pipe, and then enters the air inlet pipe. The water vapor mixes with the air and enters the carbonization chamber, so that the high-temperature charcoal reacts with the water vapor to produce carbon monoxide, thereby increasing the efficiency of carbon monoxide production from the charcoal, further increasing the combustion efficiency of combustible gas in the gasification chamber, and further increasing the heating efficiency of the stove body. The heated air in the stove body is then filled into the flue through the smoke exhaust hole to heat the kang body and ensure that the kang body is at a suitable temperature.

[0012] 2. The household gas-fired carbonization stove and kang (heated brick bed) device of the present invention, when the water tank moves downward, drives the support rod through the No. 2 pipe, which in turn pushes the wedge block to slide. The wedge block drives the push plate to move through the sliding column, which in turn drives the flip plate to rotate and increases the ventilation efficiency of the smoke exhaust hole. This results in a lower ventilation efficiency of the smoke exhaust hole when the stove is ignited, which accelerates the accumulation of heat in the stove and increases the efficiency of the fuel to reach the optimal combustion temperature, thus increasing the combustion efficiency of the fuel. When the temperature inside the stove rises, the push plate moves and drives the flip plate to rotate, increasing the ventilation efficiency of the smoke exhaust hole, which in turn allows more oxygen to enter the stove to participate in combustion, further increasing the heating efficiency of the stove.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 6 As shown, the household gasification and carbonization stove and kang device of the present invention includes a kang body 1; a stove body 2 is provided on one side of the kang body 1, and a flue 11 is provided on the other side; a base 12 is provided at the bottom of the kang body 1, and a flue 13 is provided between the base 12 and the kang body 1; one side of the flue 13 is connected to the flue 11, and the other side is connected to the stove body 2; an outer wall 14 is provided on the side of the kang body 1 closest to the flue 11, and a partition wall 15 is provided on the other side; a feed inlet 21 is provided on the side of the stove body 2 away from the kang body 1, and a furnace cover 22 is provided on the top of the stove body 2; a first grate 23 and a second grate 23 are arranged sequentially from bottom to top inside the stove body 2. The grate 24, grate 23, and grate 24 divide the stove body 2 from top to bottom into a gasification chamber 25, a carbonization chamber 26, and a slag chamber 27. The carbonization chamber 26 is connected to the feed inlet 21. The carbonization chamber 26 is connected to the flue 13 through the exhaust port 3. The bottom of grate 24 is provided with an air inlet pipe 28, which is connected to the outside atmosphere. A water tank 4 is provided inside the stove body 2 near the furnace cover 22. The top of the water tank 4 is provided with a water inlet pipe 41, which is equipped with a one-way valve. The top of the water tank 4 is connected to an exhaust pipe 42. A set of jets is evenly distributed around the circumference of the air inlet pipe 28. Pipe 43, the jet pipe 43 is connected to the exhaust pipe 42 via pipe 44; during operation, in the prior art, fuel is added into the stove body 2 through the feed inlet 21, and then the fuel is ignited, causing charcoal to fall into the carbonization chamber 26, where the charcoal burns and produces carbon monoxide and carbon dioxide. The carbon monoxide enters the gasification chamber 25 and is ignited, heating the air in the stove body 2. However, in the prior art, the carbon monoxide generation efficiency in the carbonization chamber 26 is low, resulting in the charcoal not burning quickly and the fuel utilization rate is low. At this time, the heat from the combustion in the stove body 2 is used to heat the water through the water tank 4 installed inside the stove body 2. After the water in tank 4 boils, it produces steam. The steam passes through exhaust pipe 42 and pipe 44 and then enters jet pipe 43, and then into air inlet pipe 28. The steam mixes with air and enters carbonization chamber 26, where the high-temperature charcoal reacts with the steam to produce carbon monoxide, thereby increasing the efficiency of carbon monoxide production from the charcoal. This further increases the combustion efficiency of combustible gas in gasification chamber 25 and the heating efficiency of stove 2. The heated air in stove 2 is then fed into flue 13 through exhaust port 3 to heat kang body 1 and ensure that kang body 1 is at a suitable temperature.

[0023] In one embodiment of the present invention, the jet pipe 43 is inclined upward on the side near the center of the air inlet pipe 28; an L-shaped bracket 45 is fixedly connected to the bottom of one end of the jet pipe 43 located inside the air inlet pipe 28, and a cover plate 46 is hinged to the end of the bracket 45 away from the jet pipe 43. A tension spring 47 is fixedly connected between the cover plate 46 and the bracket 45; the tension spring 47 drives the cover plate 46 to press and seal the jet pipe 43, reducing the amount of ash produced by charcoal combustion entering the jet pipe 43 and blocking the jet pipe 43, thereby further increasing the reaction efficiency of water vapor and charcoal. At the same time, in conjunction with the jet pipe 43 being inclined upward on the side near the center of the air inlet pipe 28, the high-speed water vapor ejected from the jet pipe 43 accelerates the air flow rate inside the air inlet pipe 28, thereby further increasing the oxygen supply in the stove body 2, increasing the combustion efficiency of combustible materials, and further increasing the heating efficiency of the stove body 2.

[0024] In one embodiment of the present invention, a second pipe 5 is fixedly connected to the bottom of the water tank 4, and a first pipe 44 is sleeved inside the second pipe 5 and slidably sealed to the second pipe 5; a rotating cavity 51 is provided in the middle of the first pipe 44, and a first shaft 52 is provided inside the rotating cavity 51. One end of the first shaft 52 passes through the rotating cavity 51 and extends to the outside of the rotating cavity 51; the first shaft 52 is rotatably sealed to the rotating cavity 51, and a water wheel 53 is fixedly connected to one end of the first shaft 52 located in the rotating cavity 51, and a gear 54 is fixedly connected to the other end; a rack 55 is fixedly connected to the bottom of the water tank 4 at a position corresponding to the gear 54, and the rack 55 meshes with the gear 54; the top of the water tank 4 is fixedly connected to the stove body 2 by a spring; when fuel is added to the stove body 2 and ignited, the combustion efficiency of the fuel is relatively low due to the low temperature inside the stove body 2. When the water tank 4 is pulled to a higher position by the spring, the heat absorption of the fuel combustion by the water tank 4 is reduced, which allows the stove body 2 to heat up quickly and reach the appropriate combustion temperature. When the temperature inside the stove body 2 rises, the fuel burns completely and releases heat. At this time, the temperature in the water tank 4 gradually rises. After the water in the water tank 4 boils, the steam is ejected from the jet pipe 43 through pipe 44 and pipe 5. The steam drives the water wheel 53 to rotate, which in turn drives shaft 52 and gear 54 to rotate, which in turn drives the water tank 4 to move downward, reducing the distance between the flame inside the stove body 2 and the water tank 4, increasing the heating efficiency of the water tank 4, further increasing the steam generation rate, and thus increasing the carbon monoxide generation efficiency, and further increasing the heating efficiency of the stove body 2.

[0025] In one embodiment of the present invention, the water tank 4 is rotatably connected to an annular flexible shaft 56 via a bracket 45, and a set of bristles 57 are evenly distributed around the circumference of the flexible shaft 56; a first bevel gear 58 is fixedly connected to the flexible shaft 56, and a second shaft 59 is provided on the water tank 4 at a position corresponding to the first bevel gear 58, the second shaft 59 passing through the water tank 4 and being rotatably and sealingly connected to the water tank 4; a second bevel gear 60 is fixedly connected to the end of the second shaft 59 near the first bevel gear 58, and the second bevel gear 60 meshes with the first bevel gear 58; a first rotating shaft is fixedly connected to the end of the second shaft 59 away from the first bevel gear 58. A second rotating wheel 62 is fixedly connected to the first rotating wheel 61 at the corresponding position on the first shaft 52. A flexible steel belt is sleeved between the first rotating wheel 61 and the second rotating wheel 62. When the first shaft 52 rotates, it drives the second rotating wheel 62, which in turn drives the first rotating wheel 61 to rotate through the steel belt. This causes the second shaft 59 to drive the flexible shaft 56 to rotate through the second bevel gear 60 and the first bevel gear 54. Finally, it drives the brush bristles 57 to rotate and clean the inner wall of the water tank 4, reducing the adhesion and accumulation of scale on the inner wall of the water tank 4, thereby increasing the heat transfer efficiency of the water tank 4, further increasing the steam generation efficiency, and increasing the heating efficiency of the stove body 2.

[0026] In one embodiment of the present invention, a flap 64 is hinged to the smoke exhaust hole 3 via a pivot pin 63, and a torsion spring 65 for assisting the flap 64 in resetting is sleeved on the pivot pin 63; a sliding column 67 is slidably connected in the sliding groove 66 at the bottom of the smoke exhaust hole 3, and a reset spring is provided between the sliding column 67 and the side wall of the sliding groove 66; a wedge block 68 is fixedly connected to the other end of the sliding column 67; a push plate 69 is fixedly connected to the sliding column 67 on the side of the flap 64 near the water tank 4; a wedge block 68 is fixedly connected to the end of the sliding column 67 near the second pipe 5; a support rod 70 is fixedly connected to the side of the second pipe 5 at a position corresponding to the wedge block 68, and the support rod 70 is slidably connected to the wedge block 68. When the support rod 70 moves downward, it pushes the sliding column 67 away from the water tank 4. The second pipe 5 slides on one side; when the water tank 4 moves downward, the second pipe 5 drives the support rod 70, which in turn pushes the wedge block 68 to slide. The wedge block 68 drives the push plate 69 to move through the sliding column 67, which in turn drives the flip plate 64 to rotate and increases the ventilation efficiency of the smoke exhaust hole 3. This results in a lower ventilation efficiency of the smoke exhaust hole 3 when the stove body 2 is ignited, which accelerates the accumulation of heat in the stove body 2 and increases the efficiency of the fuel to reach the optimal combustion temperature, thus increasing the combustion efficiency of the fuel. When the temperature inside the stove body 2 rises, the push plate 69 moves and drives the flip plate 64 to rotate, increasing the ventilation efficiency of the smoke exhaust hole 3, which in turn allows more oxygen to enter the stove body 2 to participate in combustion, further increasing the heating efficiency of the stove body 2.

[0027] In one embodiment of the present invention, a set of horizontally placed U-shaped pipes 71 are provided at the top of the flue 13. The upper part of the U-shaped pipes 71 is embedded inside the stove body 2 and connected to the water tank 4 through a flexible hose. The other end of the U-shaped pipes 71 is connected to the water tank 4 through a water pipe and a circulation pump. Through the connection between the U-shaped pipes 71 and the water tank 4, and by continuously increasing the circulation speed of the hot water in the water tank 4 through the circulation pump, the heat storage capacity of the stove body 2 is increased, the heating uniformity of the stove body 2 is further increased, and the heat preservation effect of the stove body 2 is increased.

[0028] In operation, existing technology involves adding fuel to the stove body 2 through the feed inlet 21, then igniting the fuel, causing charcoal to fall into the carbonization chamber 26. The charcoal burns, producing carbon monoxide and carbon dioxide. The carbon monoxide then enters the gasification chamber 25 and is ignited, heating the air in the stove body 2. However, the carbon monoxide generation efficiency in the carbonization chamber 26 is low, resulting in slow combustion of the charcoal and low fuel utilization. To address this, a water tank 4 is installed inside the stove body 2. The heat from the combustion in the stove body 2 heats the water tank 4, causing the water in the tank 4 to boil and produce steam. This steam passes through the exhaust pipe 42 and the first pipe 44, then enters the jet pipe 43, and finally the air intake pipe 28. The steam mixes with the air and then enters the carbonization chamber 26. This process allows the high-temperature charcoal to react with water vapor to produce carbon monoxide, thereby increasing the efficiency of carbon monoxide production from the charcoal. This further increases the combustion efficiency of combustible gases in the gasification chamber 25 and the heating efficiency of the stove body 2. The heated air in the stove body 2 is then introduced into the flue 13 through the exhaust port 3 to heat the kang body 1, ensuring it is at a suitable temperature. The tension spring 47 causes the cover plate 46 to press and seal the jet pipe 43, reducing the amount of ash from charcoal combustion entering and clogging the jet pipe 43. This further increases the reaction efficiency between water vapor and charcoal. Simultaneously, the jet pipe 43, tilted upwards near the center of the air inlet pipe 28, accelerates the flow of high-speed water vapor from the jet pipe 43 into the air inlet pipe 28. The increased airflow further increases the oxygen supply within the stove body 2, increasing the combustion efficiency of combustible materials and thus further increasing the heating efficiency of the stove body 2. When fuel is added to and ignited in the stove body 2, the combustion efficiency is low due to the low temperature inside the stove body 2. At this time, the spring pulls the water tank 4 to a higher position in the stove body 2, reducing the absorption of heat generated by fuel combustion by the water tank 4, thereby allowing the stove body 2 to heat up rapidly and accelerate the stove body 2 to reach the appropriate combustion temperature. When the temperature inside the stove body 2 rises, the fuel burns completely and releases heat. At this time, the temperature in the water tank 4 gradually rises. After the water in the water tank 4 boils, the steam is ejected from the jet pipe 43 through pipe 44 and pipe 5. At this time, the steam drives the water wheel 53 to rotate. This drives the first shaft 52 and gear 54 to rotate, which in turn causes the water tank 4 to move downwards, reducing the distance between the flame inside the stove body 2 and the water tank 4, increasing the heating efficiency of the water tank 4, further increasing the steam generation rate, and thus increasing the carbon monoxide generation efficiency, and further increasing the heating efficiency of the stove body 2; when the first shaft 52 rotates, it drives the second rotating wheel 62, which in turn drives the first rotating wheel 61 to rotate via the steel belt, so that the second shaft 59 drives the flexible shaft 56 to rotate via the second bevel gear 60 and the first bevel gear 54, which in turn drives the brush 57 to rotate and clean the inner wall of the water tank 4, reducing the adhesion and accumulation of scale on the inner wall of the water tank 4, thereby increasing the heat transfer efficiency of the water tank 4, further increasing the steam generation efficiency, and increasing the heating efficiency of the stove body 2;When the water tank 4 moves downward, it drives the support rod 70 through the second pipe 5, which in turn pushes the wedge block 68 to slide. The wedge block 68 drives the push plate 69 to move through the sliding column 67, which in turn drives the flip plate 64 to rotate and increases the ventilation efficiency of the exhaust hole 3. This results in a lower ventilation efficiency of the exhaust hole 3 when the stove body 2 is ignited, accelerating the accumulation of heat inside the stove body 2, thereby increasing the efficiency of the fuel reaching the optimal combustion temperature and increasing the combustion efficiency of the fuel. When the temperature inside the stove body 2 rises, the push plate 69 moves and drives the flip plate 64 to rotate, increasing the ventilation efficiency of the exhaust hole 3, thereby allowing more oxygen to enter the stove body 2 to participate in combustion, further increasing the heating efficiency of the stove body 2. Through the connection between the U-shaped pipe 71 and the water tank 4, and through the continuous increase of the circulation speed of the hot water in the water tank 4 by the circulation pump, the heat storage capacity of the stove body 2 is increased, further increasing the heating uniformity of the stove body 2 and increasing the heat preservation effect of the stove body 2.
