Abstract
Description
Technical Field
[0001] This utility model relates to the field of stove technology, specifically to a multifunctional stove. Background Technology
[0002] A stove is a common structure in daily life, mainly used for heating and transferring heat for cooking, drying, etc. A typical stove includes a stove body and a flue pipe connected to the stove body. Combustible materials (such as firewood and coal) burn inside the stove body, and the smoke is discharged through the flue pipe. The heat generated by the combustion of combustible materials spreads along the stove body and exchanges heat with the air, which can heat the air for heating. The heat generated by the combustion of combustible materials can be used to cook utensils or food, and can be used to dry clothes.
[0003] However, the most common type of stove has a fire opening on the stove body. Cooking utensils can be placed in the fire opening, or food can be directly roasted or clothes dried. The exhaust pipe is located near the fire opening, which drives the smoke and flames to rise and provide high temperature. However, during use, the smoke can easily escape from the fire opening, affecting people's breathing and causing eye discomfort. At the same time, the smoke will leave a smoky smell when roasting food or drying clothes. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0022] In one embodiment, see Figure 1 , 3 This utility model discloses a multifunctional stove, which includes a stove assembly, a heating assembly, and a heating element.
[0023] The furnace assembly includes a furnace body 1, a flue pipe 2 installed on the furnace body 1, a combustion chamber 3 inside the furnace body 1, a grate 4 inside the combustion chamber 3, and a fire port 5 communicating with the combustion chamber 3 on the furnace body 1. The heating assembly includes multiple sets of heating elements 6 spirally installed in the combustion chamber 3 and a sealing element 7 installed at the fire port 5. The sealing element 7 has a sealing cavity 8 inside, and a heat distribution element 9 inside the sealing cavity 8. The sealing element 7 is connected to the fire port 5 to seal the top of the combustion chamber 3. A sealing plate 10 is provided on the sealing element 7. One end of the heating element 6 passes through the furnace and is provided with an exhaust element 11. The other end of the heating element 6 communicates with the sealing cavity 8. The heating element 12 is wound around the outer wall of the furnace body 1. The heating element 12 has heat dissipation holes 13. A first valve plate 14 is movably installed on the heating element 12 near the sealing cavity 8.
[0024] Preferably, the furnace body 1 is provided with a furnace opening 15 that communicates with the combustion chamber 3, and a furnace door 16 is provided at the furnace opening 15.
[0025] Further, see Figure 1 , 3The heating element 6 includes an air supply pipe 601 vertically disposed in the combustion chamber 3 and multiple sets of heating pipes 602 connected to the air supply pipe 601. The heating pipes 602 are spirally disposed in the combustion chamber 3 to increase the area of the heating pipes 602 in the combustion chamber 3.
[0026] Preferably, since the temperature inside the furnace body 1 after combustion is usually 1100℃, in order to ensure that the heating element 6 works normally and is not melted by the high temperature, the air supply pipe 601 and the heating pipe 602 are both made of steel pipe with a melting point of 1500℃-1600℃.
[0027] Preferably, the heating tube 602 includes straight tube sections 6021 at both ends and a spiral section 6022 in the middle.
[0028] Preferably, there is a gap between the spiral sections 6022 of the multiple sets of heating tubes 602. When the combustible material burns and generates a flame in the combustion chamber 3, the flame can pass through the space between the heating tubes 602, thereby increasing the contact area between the heating tubes 602 and the flame, and making the heating tubes 602 heat up faster.
[0029] Preferably, the spiral segment 6022 of the heating tube 602 has a multi-turn annular structure.
[0030] Further, see Figure 1 , 3 The bottom of the combustion chamber 3 is provided with an air inlet pipe 17. One end of the air inlet pipe 17 passes through the combustion chamber 3 and is connected to the exhaust pipe 11. A second valve plate 18 is provided inside the air inlet pipe 17.
[0031] Preferably, the exhaust component 11 adopts a blower in the existing structure, and the air inlet pipe 17 and the air outlet pipe 601 are respectively connected to the air outlet of the blower.
[0032] Preferably, the air inlet pipe 17 is provided with a second slot 19, and the second valve plate 18 is inserted into the second slot 19.
[0033] In the above setup, combustibles such as firewood and coal burn in the combustion chamber 3. The heat generated by the combustion acts on the air supply pipe 601 and the heating pipe 602. The blower delivers external air to the air supply pipe 601 and the heating pipe 602. The spiral structure of the heating pipe 602 increases the contact area with heat, allowing the heating pipe 602 to heat up rapidly. At the same time, it increases the travel distance of the airflow within the heating pipe 602, thereby heating the airflow and allowing the high-temperature hot air to enter the closed chamber 8. The second valve plate 18 controls the airflow delivered by the blower to enter the combustion chamber 3, which increases the oxygen supply in the combustion chamber 3, accelerates the combustion of combustibles in the combustion chamber 3, and causes the interior of the combustion chamber 3 to heat up rapidly.
[0034] Further, see Figure 1 , 3The sealing component 7 includes a sealing disc 701, the interior of which is hollow to form a sealing cavity 8. The sealing disc 701 is fixedly connected to the inner wall of the fire port 5 to seal the fire port 5.
[0035] Preferably, the closed disc 701 is a hollow disc with one end open, and the closed end of the closed disc 701 is located at the top of the combustion chamber 3.
[0036] Preferably, the straight pipe section 6021 of the heating tube 602 passes through the closed end of the closed plate 701, and the straight pipe section 6021 of the heating tube 602 is evenly arranged on the closed end of the closed plate 701, so that the hot air entering the closed cavity 8 along the heating tube 602 is dispersed in the closed cavity 8.
[0037] Preferably, the bottom end of the exhaust pipe 2 passes through the combustion chamber 3 and is located at the top of the combustion chamber 3. When the blower delivers gas to the combustion chamber 3, the flue gas in the combustion chamber 3 moves upward and is discharged along the exhaust pipe 2.
[0038] Further, see Figure 1 , 3 The heat distribution component 9 includes a heat distribution plate 901 disposed within a closed plate 701, and a plurality of heat distribution holes 902 are arranged on the heat distribution plate 901.
[0039] Preferably, a support ring 20 is provided on the inner wall of the closed plate 701, and the heat distribution plate 901 is installed on the support ring 20.
[0040] In the above configuration, the high-temperature hot gas entering the closed cavity 8 along the heat distribution tube is initially dispersed into the closed cavity 8 through the straight tube end of the heat distribution tube, and then dispersed a second time through the heat distribution hole 902 on the heat distribution plate 901, thereby dispersing the high-temperature hot gas in the closed cavity 8; the heat in the combustion chamber 3 is used not only on the heating tube 602, but also at the bottom end of the closed plate 701, further increasing the heat in the closed cavity 8.
[0041] Further, see Figure 1 , 2 The heating element 12 includes a heating pipe 1201, one end of which is connected to the combustion chamber 3, and the other end is wrapped around the outer wall of the furnace body 1.
[0042] Preferably, the opening end of the closed plate 701 is provided with a closing protrusion ring 21, and the closing plate 10 is installed on the closing protrusion ring 21, thereby covering and closing the closed cavity 8, so that the hot air in the closed cavity 8 moves into the heating pipe 1201.
[0043] Preferably, the heating pipe 1201 is provided with a first slot 22, and the first valve plate 14 is movably inserted into the first slot 22.
[0044] Preferably, the furnace body 1 is also provided with a protective cover 23, which encloses the heating pipe 1201, and there is a gap between the protective cover 23 and the heating pipe 1201.
[0045] In the above setup, when heating is needed, the sealing plate 10 can be placed on the sealing protrusion 21, or a pot can be placed on the open end of the sealing plate 701 (the pot has the same sealing effect as the sealing plate 10). This allows hot air to move into the heating pipe 1201 and be discharged from the heat dissipation hole 13, thereby raising the temperature around the furnace body 1 to achieve heating. When a pot is placed on the plate, it can also be heated for cooking.
[0046] Further, see Figure 1 , 3 A heat exhaust pipe 24 is provided between the enclosed cavity 8 and the exhaust pipe 2, and a third valve plate 25 is movably provided on the heat exhaust pipe 24.
[0047] Preferably, the heat exhaust pipe 24 is provided with a third slot 26, and the third valve plate 25 is movably located in the third slot 26.
[0048] In the above setup, if there is no heating requirement, the first valve plate 14 can be inserted into the bottom of the first slot 22 to close the heating pipe 1201, and the third valve plate 25 can be opened to connect the heat exhaust pipe 24 with the flue pipe 2, so that the hot air in the closed cavity 8 can be discharged from the heat exhaust pipe 24 into the flue pipe 2. When cooking with a pot on the closed plate 701, the hot air can be discharged from the flue pipe 2, reducing the temperature around the furnace body 1 and fulfilling the cooking requirement.
[0049] In this embodiment, the burner 5 at the top of the combustion chamber 3 is sealed by the sealing plate 701, so that the flue gas in the combustion chamber 3 can only be discharged from the exhaust pipe 2, avoiding the flue gas from escaping from the burner 5 and affecting human breathing or causing eye discomfort. The heating pipe 602 set in the combustion chamber 3 heats the external airflow and delivers it to the sealed chamber 8, so that high-temperature hot air is used for cooking and roasting, realizing operations such as heating cookware or roasting food at high temperature, and drying clothes, avoiding the flue gas from acting on food and clothes. During the cooking and drying process, the heating pipe 1201 can be selectively controlled to be turned on or off, so that the hot air in the sealed chamber 8 can be delivered to the area around the furnace body 1 for heating through the heating pipe 1201, or directly discharged through the exhaust pipe 2.
[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
