Description

Technical Field

[0001] This invention relates to the field of stove technology, and in particular to a multi-functional heating stove that can be used for various fuels. Background Technology

[0002] Heating stoves are common heating devices used in people's daily lives and are widely used in homes, offices, hotels, shopping malls, hospitals, schools and other facilities.

[0003] Existing heating stoves can be categorized into electric stoves, wood-fired stoves, oil-fired stoves, gas-fired stoves, and coal-fired stoves, depending on the fuel used or the heating principle employed. However, existing stoves typically only support one type of fuel or employ a single heating method. Furthermore, their structure is usually designed based on the type of fuel or heating method used, resulting in a limited range of fuel options. Users must use the corresponding type of fuel when they need heating, indicating a significant limitation in fuel selection for current heating stoves. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-functional, universal fuel-based heating stove, which solves the problem of limited fuel selection in existing heating stoves.

[0005] According to an embodiment of the present invention, a multi-functional fuel-based heating stove includes a stove body, a flue gas exhaust assembly on the stove body, an air inlet at the bottom of the stove body, and a combustion assembly including a shell disposed within the stove body and the shell forming a combustion chamber. The shell has a plurality of first through holes spaced apart, an air outlet communicating with the flue gas exhaust assembly at the top, and first and second feed inlets respectively on opposite sides of the shell. A first feeding assembly includes an extension disposed on the stove body, the extension forming a feeding channel communicating with the interior of the stove body. One end of the feed channel is located near the first feed inlet; the second feeding assembly includes an auger and a hopper that cooperates with the auger, with the end of the auger away from the hopper passing through the furnace body and cooperating with the second feed inlet; the gas supply assembly includes a first conduit and a blower that cooperates with the first conduit, with one end of the first conduit extending into the furnace body and communicating with the air inlet; the electric heating assembly includes an electric heating tube disposed in the furnace body, the electric heating tube surrounding the shell; the control assembly includes a controller, and the auger, the blower and the electric heating tube are respectively electrically connected to the controller.

[0006] Compared with the prior art, the present invention has the following beneficial effects: By employing a combustion chamber located inside the furnace body to accommodate solid fuel, and with a first feed port and a second feed port respectively provided on both sides of the shell surrounding the combustion chamber, manual feeding can be performed through the feeding channel in the first feeding assembly from the first feed port, or automatic feeding can be performed through the auger and hopper in the second feeding assembly from the second feed port. Furthermore, the multi-functional fuel-based heating furnace can also heat the furnace body by introducing hot gas into the furnace body through the first conduit and blower in the gas supply assembly, or by heating the interior of the furnace body through the electric heating element in the electric heating assembly. Moreover, the aforementioned auger, blower, and electric heating element can all be controlled... The controller in the control unit switches the furnace on and off, solving the technical problem of the limited fuel selection in existing heating stoves. This results in a wider range of fuel selection for multi-fuel multi-functional heating stoves, allowing them to choose the heating method according to actual needs, thus improving their versatility. Furthermore, by combining the positional and cooperative relationships of the furnace body, combustion components, first feeding components, second feeding components, gas supply components, electric heating components, and control components, the multi-fuel multi-functional heating stove achieves intelligent operation, making it more convenient for users.

Detailed Implementation

[0009] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0010] like Figures 1 to 11 As shown in the figure, this embodiment of the invention proposes a multi-functional fuel-based heating stove, which includes a stove body 100, a flue gas assembly 200, a combustion assembly 300, a first fuel feeding assembly 400, a second fuel feeding assembly 500, a gas supply assembly 600, an electric heating assembly 700, and a control assembly 800. The multi-functional fuel-based heating stove can generate heat through multiple methods such as burning fuel, supplying heating gas, and electric heating to meet the user's needs in different scenarios.

[0011] Please refer to Figure 1 and Figure 4The multi-fuel multi-functional heating stove includes a base 102 and a stove body 100 mounted on the base 102. The bottom of the stove body 100 has an air inlet 101 for air to enter the stove body 100, and the air inlet 101 is connected to the air supply assembly 600. The exhaust assembly 200 is mounted on the stove body 100 and communicates with the interior of the stove body 100 to exhaust waste gas generated inside the stove body 100. The combustion assembly 300 includes a housing 301 disposed within the furnace body 100. The housing 301 encloses a combustion chamber 302 for containing fuel. The housing 301 has a plurality of first through holes 303 spaced apart to allow gas to enter the housing 301. The top of the housing 301 has an outlet 304 communicating with the exhaust assembly 200. The housing 301 has a first feed inlet 305 and a second feed inlet 306 on opposite sides. The first feed inlet 305 is used by the first feeding assembly 400 to add fuel to the combustion chamber 302, and the second feed inlet 306 is used by the second feeding assembly 500 to add fuel to the combustion chamber 302.

[0012] Specifically, when the multi-functional fuel-based heating furnace uses fuel combustion for heating, the high temperature generated when the fuel burns and releases heat in the combustion chamber 302, and the airflow generated when the gas in the combustion chamber 302 is discharged from the exhaust assembly 200, will create a negative pressure in the combustion chamber 302. Consequently, the gas supplied by the gas supply assembly 600 into the furnace body 100 will pass through the first through hole 303 on the shell 301 and enter the combustion chamber 302, thereby keeping the fuel in the combustion chamber 302 in a state of combustion and causing the temperature in the combustion chamber 302 to rise rapidly to achieve heating.

[0013] Please combine Figure 5 and Figure 6In this embodiment, the housing 301 includes a first conical portion 310 and a second conical portion 311 connected together. The first conical portion 310 is located above the second conical portion 311, and the first feed inlet 305 and the second feed inlet 306 are both disposed on the first conical portion 310. The air outlet 304 is located at the end of the first conical portion 310 away from the second conical portion 311. The second conical portion 311 is provided with a furnace bridge 308 for supporting fuel. The furnace bridge 308 is located below the first feed inlet 305 and the second feed inlet 306, and the end of the second conical portion 311 away from the first conical portion 310 has an ash discharge port 307, which allows the ash generated after fuel combustion to be discharged from the combustion chamber 302. Furthermore, the diameter of the connection between the first conical portion 310 and the second conical portion 311 is larger than the diameter of the air outlet 304 and the diameter of the ash outlet 307, so that the heat generated by fuel combustion is fully utilized and the combustion chamber 302 can be heated rapidly.

[0014] Optionally, the housing 301 may also be one or a combination of cylindrical, conical, spherical, ellipsoidal, and frustum-shaped.

[0015] like Figure 3 and Figure 6 As shown, in order to fix the housing 301 inside the furnace body 100, a plurality of fixing plates 103 are arranged vertically at intervals inside the furnace body 100. The fixing plates 103 are fixedly connected to the inner wall of the furnace body 100 and the housing 301 respectively, so that the position of the housing 301 inside the furnace body 100 remains stable. The fixing plates 103 are respectively provided with through holes 104 penetrating the fixing plates 103 so that the gas supplied by the gas supply assembly 600 can reach various areas inside the furnace body 100, ensuring that the gas supplied into the combustion chamber 302 meets the requirements for fuel combustion.

[0016] In detail, the housing 301 is also provided with a cover 105, which surrounds the air outlet 304 and the two ends of the cover 105 are respectively fixedly connected to two adjacent fixing plates 103. The cover 105 is used to separate the first through hole 303 from the exhaust assembly 200 to prevent the gas input by the gas supply assembly 600 from being directly discharged from the exhaust assembly 200 to the outside of the furnace body 100, and to prevent the exhaust gas discharged from the air outlet 304 from re-entering the combustion chamber 302 through the first through hole 303 and affecting the normal combustion of fuel.

[0017] like Figure 4 and Figure 5As shown, the base 102 is provided with an ash box 110 for collecting ash falling from the ash outlet 307. The ash box 110 is located directly below the ash outlet 307 and can be pulled out of the base 102 for easy cleaning by the user. The base 102 is also provided with a movable ash discharge damper 111 and a pull rod 112 for moving the ash discharge damper 111. The ash discharge damper 111 is located between the furnace bridge 308 and the ash box 110, and is located directly below the housing 301. By pulling the pull rod 112, the ash discharge damper 111 can be moved directly below the ash outlet 307 or moved away from directly below the ash outlet 307. When the ash discharge damper 111 is located directly below the ash discharge port 307, the ash falling from the combustion chamber 302 first falls onto the ash discharge damper 111, and then the ash on the ash discharge damper 111 can be shaken off into the ash box 110 by pulling the lever 112 to move the ash discharge damper 111.

[0018] Please combine Figure 2 and Figure 4 The first feeding component 400 includes an extension 401 fixedly connected to the furnace body 100. The extension 401 forms a feeding channel 402 that communicates with the interior of the furnace body 100. One end of the feeding channel 402 that communicates with the interior of the furnace body 100 is located near the first feed inlet 305. When adding fuel manually, a tool is used to pass the fuel through the feeding channel 402 and the first feed inlet 305 in sequence and put it into the combustion chamber 302 to complete the feeding. The feeding channel 402 can be used for solid fuels such as wood, charcoal, and honeycomb briquettes. Other types of fuels can also be placed in the combustion chamber 302 using a container.

[0019] Preferably, the extension 401 is also provided with a rotatable cover plate 403, which covers the opening of the feeding channel 402 away from the first feed port 305. When fuel needs to be added, rotating the cover plate 403 will open the feeding channel 402, and fuel can be put into the combustion chamber 302 through the feeding channel 402. After the feeding operation is completed, rotating the cover plate 403 will close the feeding channel 402 to prevent heat from being lost from the feeding channel 402 and ensure that the temperature inside the furnace body 100 is kept within an appropriate range.

[0020] Please refer to Figure 4 and Figure 12The multi-fuel multifunctional heating furnace also includes an oil-water box 309, which is used to hold liquid fuel, such as fuel oil. The oil-water box 309 can enter and exit the combustion chamber 302 through the feeding channel 402 and the first feeding port. The oil-water box 309 has a separated first chamber 312 and a second chamber 313. When using the oil-water box 309 to hold fuel, liquid fuel can be placed in either the first chamber 312 or the second chamber 313, or liquid fuel can be placed in one of the first chamber 312 and the second chamber 313 and water can be placed in the other. When liquid fuel and water are placed in the oil-water box 309 at the same time, the water placed in the oil-water box 309 will evaporate and produce water vapor as the liquid fuel burns. The water vapor will react with the carbon produced by the combustion of the liquid fuel to form water gas, ensuring that the liquid fuel burns completely and releases heat, thereby improving the heating efficiency of the multi-fuel multifunctional heating furnace.

[0021] like Figure 2 and Figure 3 As shown, the second feeding assembly 500 includes an auger 501 and a hopper 502 that cooperates with the auger 501. One end of the auger 501, away from the hopper 502, passes through the furnace body 100 and cooperates with the second feed inlet 306. The auger 501 includes blades and a motor 503 that drives the blades to rotate. After adding coal, wood chips, or pellet fuel to the hopper 502, starting the motor 503 automatically feeds the fuel into the combustion chamber 302 through the rotation of the blades, achieving automatic feeding.

[0022] Please combine Figure 2 , Figure 7 and Figure 8 The gas supply assembly 600 includes a first conduit 601 and a blower 602 that cooperates with the first conduit 601. One end of the first conduit 601 passes through the base 102 and extends into the furnace body 100, and the first conduit 601 is connected to the air inlet 101. When the multi-fuel multi-functional heating furnace heats the room by introducing hot gas, the hot gas from the outside is injected into the first conduit 601 and then blown into the furnace body 100 by the blower 602, thereby heating the base 102 and the interior of the furnace body 100.

[0023] Optionally, the gas supply assembly 600 further includes a plurality of branch pipes 603 respectively connected to the first conduit 601. The branch pipes 603 respectively pass through the air inlet 101 and extend into the furnace body 100. The branch pipes 603 respectively cooperate with the through hole 104 so that the branch pipes 603 are vertically arranged in the furnace body 100. The lengths of the various branch pipes 603 are not exactly the same, so that the gas input into the furnace body 100 through the gas supply assembly 600 can evenly reach various areas in the furnace body 100.

[0024] like Figure 8 , Figure 10 and Figure 11 As shown, the gas supply assembly 600 also includes a transfer pipe 604 connected to the end of the first conduit 601 away from the furnace body 100. The transfer pipe 604 is used to connect the gas supply assembly 600 to an external source of hot gas. The adapter pipe 604 includes a first pipe body 605 and a second pipe body 606. The first pipe body 605 is fixed on the base 102. The second pipe body 606 is sleeved on the first pipe body 605 and can move relative to the first pipe body 605 along the axis of the first pipe body 605. The first pipe body 605 is connected to the first conduit 601, and a first vent hole 607 penetrating the first pipe body 605 is provided on the outer peripheral wall of the first pipe body 605. A second vent hole 608 penetrating the second pipe body 606 is provided on the second pipe body 606. By moving the second pipe body 606, the first vent hole 607 and the second vent hole 608 can be connected or misaligned. The end of the second pipe body 606 away from the base 102 has a third vent hole 612 and an end cap 611 covering the third vent hole 612. The end cap 611 is detachably connected to the second pipe body 606.

[0025] Specifically, when the second tube 606 is moved to align the first vent 607 with the second vent 608, the outlet of the externally supplied hot gas source can pass through the second vent 608 and the first vent 607 in sequence, connecting the first tube 605 with the externally supplied hot gas source. At this time, the end cap 611 closes the third vent 612, allowing hot gas to be introduced into the first conduit 601 through the first tube 605, thereby supplying hot gas into the furnace body 100. When it is necessary to introduce room temperature gas into the furnace body 100 to ensure the combustion chamber... When the fuel in 302 is burning normally, or when the temperature inside the furnace body 100 is too high and cold gas needs to be introduced to lower the temperature inside the furnace body 100 to a suitable range, the second tube 606 is moved relative to the first tube 605 by pushing and pulling, and the first vent 607 and the second vent 608 are misaligned. At this time, the second tube 606 closes the first vent 607, and then the end cap 611 is opened so that cold gas can be introduced from the third vent 612, so that the user can adjust the type of gas introduced by the gas supply component 600 according to the needs.

[0026] like Figure 10 As shown, to limit the travel distance of the second tube 606 relative to the first tube 605, a groove 609 penetrating the second tube 606 is provided on the outer peripheral wall of the second tube 606. A positioning rod 610 is provided on the outer peripheral wall of the second tube 606, and the positioning rod 610 extends into the groove 609. When the second tube 606 moves to the point where the positioning rod 610 abuts against the inner wall of the groove 609, the second tube 606 cannot continue to move, thereby preventing the second tube 606 from accidentally detaching from the first tube 605. Furthermore, by setting the length of the groove 609, when the positioning rod 610 abuts against one end of the groove 609, the first vent 607 and the second vent 608 are aligned. When the positioning rod 610 abuts against the other end of the groove 609, the second tube 606 completely closes the first vent 607 to facilitate user operation.

[0027] like Figure 4 and Figure 6 As shown, the electric heating component 700 includes an electric heating tube 701 disposed within the furnace body 100, the electric heating tube 701 surrounding the shell 301. When the multi-fuel multi-functional heating furnace uses electric heating, turning on the electric heating tube 701 heats the interior of the furnace body 100, causing the temperature of the shell 301 to rise and be conducted to the outside.

[0028] Please combine Figure 1 , Figure 7 and Figure 9 In this embodiment, the control component 800 includes a controller 801 and multiple control buttons 802 for operating the controller 801. The controller 801 is disposed within the base 102, and the control buttons are located on the surface of the base 102. The motor 503, the blower 602, and the heating element 701 are electrically connected to the controller 801. By operating the corresponding control buttons 802, the motor 503, the blower 602, and the heating element 701 can be switched on and off, realizing intelligent control of each component of the multi-fuel multi-functional heating furnace, which is convenient for user operation. Furthermore, the base 102 is also provided with a partition 113 for protecting the control component 800. The partition 113 is used to prevent heat from the combustion chamber 302 from being transferred to the controller 801, preventing the control component 800 from malfunctioning due to high temperature.

[0029] like Figure 7 The base 102 is also equipped with an atomizer 900 and a second conduit that cooperates with the atomizer 900. The atomizer 900 is electrically connected to the controller 801. One end of the second conduit away from the atomizer 900 passes through the air inlet and extends into the furnace body 100. When firewood or charcoal is burned in the combustion chamber 302, the water mist sprayed into the furnace body 100 by the atomizer 900 will turn into high-temperature water vapor under high temperature. The high-temperature water vapor reacts with the carbon in the firewood or charcoal to form water gas, thereby ensuring complete combustion of the fuel and improving the heating efficiency of the multi-fuel multi-functional heating furnace.

[0030] like Figure 3 and Figure 4 As shown, in this embodiment, the furnace body 100 is provided with a flue seat 114 for mounting the smoke exhaust assembly 200. The flue seat 114 communicates with the interior of the furnace body 100. The smoke exhaust assembly 200 includes a plug-in seat 201 that mates with the flue seat 114 and a smoke exhaust pipe 203 disposed on the plug-in seat 201. The plug-in seat 201 is hollow and is also provided with a plug-in interface 202 for accommodating one end of the smoke exhaust pipe 203. The position of the exhaust pipe 203 can be fixed by inserting the end into the plug interface 202. Then, the flue seat 114 can be inserted into the plug seat 201 to fix the plug seat 201 and the exhaust pipe 203 on the furnace body 100. The cooperation between the flue seat 114 and the plug seat 201 makes the exhaust pipe 203 connected to the inside of the furnace body 100, so as to ensure that the exhaust gas generated in the combustion chamber 302 is stably discharged from the furnace body 100 through the exhaust pipe 203.

[0031] Please refer to Figure 2 and Figure 5The oven body 100 is also equipped with a baffle 109, which, together with the inner wall of the oven body 100, forms a space separated from the shell 301. Food can be placed in this space and baked using the heat generated in the combustion chamber 302. The oven body 100 is also equipped with a rotatable cabinet door 108, which can be rotated to open or close the space, facilitating the placement of food or the removal of baked food. Baking trays, racks, or skewering can be placed in this space for baking food.

[0032] like Figure 1 and Figure 4 As shown, the multi-fuel multi-functional heater also includes a tabletop 106. The tabletop 106 is disposed on the top of the heater body 100, and the top surface of the heater body 100 has an opening 107 penetrating through the heater body 100. The tabletop 106 covers the opening 107 to heat the tabletop through the heat inside the heater body 100. Food, cooking utensils, etc. can be placed on the tabletop, so that food can be cooked on the tabletop 106 or cooked food can be placed on the tabletop 106 to keep it warm, making the multi-fuel multi-functional heater more practical.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
