Abstract
Description
Technical Field
[0001] The invention relates to a gas stove, in particular to a heat radiation plane environment-friendly gas stove with a double-layer partition wall type heat regenerator for waste heat recovery. Technical Background
[0002] Currently, common gas stoves consist of a stove housing, a burner plate, a pot support, and other parts. The combustion method is generally an open gas stove with an exposed stove plate, also known as an atmospheric stove. In actual use, existing open gas stoves have the following major defects:
[0003] Existing gas stoves have low thermal efficiency and large heat loss. The main reason is that when the open-burning flame heats the pot, the outer flame also heats the surrounding air without participating in the heating of the pot body. Only a part of the flame heat energy and radiation is absorbed by the bottom of the pot, and the temperature of the flue gas is still very high when it leaves the pot. Due to the lack of any heat recovery device, large amounts of heat from these two parts are discharged into the indoor air environment of the kitchen, resulting in huge energy waste.
[0004] Various chemical pollutants generated by the open combustion of existing gas stoves, such as carbon monoxide, nitrogen oxides and other toxic and harmful gases, are all discharged into the indoor air, polluting the indoor environment and endangering the health of users.
[0005] The high-temperature exhaust gas emitted by the open combustion of existing gas stoves generates heat pollution in the kitchen, especially in the summer, when the cooking environment is extremely hot and the air environment in the kitchen is poor, which endangers the health of users.
[0006] Common gas stoves consist of a stove housing, a hob burner, and a pot support. During everyday cooking, spills inevitably form, and the resulting dirt and clumps can stick to these parts, making them difficult to clean. Accumulated oil can even clog the flame outlet, causing the gas flame to weaken or even fail to ignite. This not only wastes gas but also poses a significant safety hazard. Summary of the Invention
[0007] To address the problems associated with open-top gas stoves, the present invention aims to provide an energy-saving, environmentally friendly gas stove in which the cookware is placed on a flat, high-temperature resistant micro-ceramic glass plate atop the gas stove. The stove utilizes the thermal radiation generated by the combustion of gas on the upper surface of a porous medium plate burner for heating. The stove features a closed combustion chamber that isolates high-temperature flue gas and thermal radiation from the indoor air, with waste heat recovered by a double-walled heat regenerator and exhaust gases discharged outdoors through an exhaust pipe. This design effectively improves stove thermal efficiency, significantly reduces energy waste, and effectively reduces thermal pollution from high-temperature exhaust gases in the kitchen. It also effectively reduces chemical pollutants in the kitchen environment. It effectively eliminates the safety hazard of cooking stains clogging the burner holes in the stovetop burner. The easy-to-clean flat glass heat-radiating heating plate effectively reduces the tedious daily cleaning of the gas stove.
[0008] The technical solution of the present invention is a flat, environmentally friendly gas stove with a double-layer partition wall and heat radiation. It is a new type of energy-saving and environmentally friendly gas stove that heats the pot by using a closed combustion chamber that isolates high-temperature flue gas from indoor air when the pot is heated, and heat radiation generated by the combustion of gas on the surface of a porous medium plate burner through a flat, high-temperature resistant microcrystalline glass plate on the top of the gas stove. Waste heat is recovered by a double-layer partition wall regenerator. The gas stove comprises a flat high-temperature resistant microcrystalline glass plate; a gas stove upper shell; a high-temperature resistant heat-insulating sealing felt ring; a heat-insulating combustion chamber; a porous medium plate burner; an ignition needle; a flameout protection needle; a flue gas hole; a burner mixed gas inlet; a flue gas pipe; an air-gas full premixing pipe; a full premixing pipe air inlet interface; a full premixing pipe mixed gas outlet interface; a full premixing pipe gas nozzle interface; a gas regulating valve; a gas regulating knob; a gas nozzle; a double-layer partition wall type heat exchanger; a double-layer partition wall type heat exchanger air inlet; a double-layer partition wall type heat exchanger air outlet; a double-layer partition wall type heat exchanger exhaust gas inlet; a double-layer partition wall type heat exchanger exhaust gas outlet; a gas inlet pipe; a gas inlet solenoid valve; an exhaust gas exhaust pipe; an electronic igniter; a circuit control module; a power socket; a main power switch; a combustion-supporting blower; a gas supply connecting pipe; a gas stove bottom shell; an ignition wire outlet hole; a heat-insulating combustion chamber support; a double-layer partition wall type heat exchanger support; a gas stove support leg and other devices.
[0009] The flat high-temperature resistant microcrystalline glass plate is installed on the top of the upper shell of the gas stove, and the cookware is placed on the flat high-temperature resistant microcrystalline glass plate when in use.
[0010] The bottom of the flat high-temperature resistant microcrystalline glass plate is covered on a high-temperature resistant heat-insulating sealing felt ring that is attached to the flanged ring on the top of the heat-insulating combustion chamber.
[0011] The described heat-insulating combustion chamber is fixedly arranged on the bottom shell of the gas stove. The outer side wall of the heat-insulating combustion chamber is covered with a high-temperature resistant heat-insulating felt. A high-temperature resistant heat-insulating sealing felt ring is fitted on the top flanging ring of the heat-insulating combustion chamber, so as to isolate the high-temperature waste flue gas in the flat high-temperature resistant microcrystalline glass plate and the cylindrical heat-insulating combustion chamber from the room, forming a closed combustion chamber.
[0012] The porous medium plate burner is fixed in the heat-insulating combustion chamber. The medium material of the porous medium plate can be made of ceramics or metals. The porous medium combustion plate converts the heat energy generated by combustion into infrared heat radiation, which passes through the flat high-temperature resistant microcrystalline glass plate, effectively transferring the heat energy so that the heated cookware can absorb the heat energy. The high-temperature waste flue gas in the closed combustion chamber cannot be discharged through any other channels, and can only be discharged into the waste gas inlet of the double-layer partition heat regenerator through the flue gas holes arranged at the bottom of the fixed heat-insulating combustion chamber, and finally discharged from the waste gas exhaust pipe into the kitchen room.
[0013] The described double-layer partition heat regenerator is made of metal materials and is fixedly installed on the bottom shell of the gas stove by support columns. The double-layer partition heat regenerator has a coiled structure feature that extends from the inner circle to the outer circle in an involute form, coils outside the outer circle of the heat-insulating combustion chamber and maintains a certain distance. The channels of the double-layer partition heat regenerator have a rectangular "day" - shaped cross-sectional structure, and are divided into a lower-layer waste gas channel and an upper-layer air channel by an intermediate plate layer. The two ends of the lower-layer waste gas channel are respectively provided with two holes, namely: the waste gas inlet at the inner circle end and the waste gas outlet at the outer circle end. The waste gas inlet is fixedly connected to the flue gas hole of the heat-insulating combustion chamber by a flue gas pipe, and the waste gas outlet is fixedly connected to the waste gas discharge pipe. The two ends of the upper-layer air channel of the double-layer partition heat regenerator are respectively provided with two holes, namely: the air outlet at the inner circle end and the air inlet at the outer circle end. The air outlet is fixedly connected to the air-gas full-premixing pipe, and the air inlet is fixedly connected to the air outlet of the combustion-supporting blower.
[0014] After combustion, the high-temperature waste gas is discharged from the flue gas holes under the action of the air pressure of the combustion-supporting blower, passes through the flue gas pipe, and then continues to be discharged into the waste gas inlet at the inner circle end of the double-layer partition heat regenerator. When the high-temperature waste flue gas flows in the waste gas channel with a relatively long dimension of the double-layer partition heat regenerator, it releases heat to the double-layer partition heat regenerator. At the same time, the normal-temperature air flowing in the opposite direction is gradually heated when it is discharged by the combustion-supporting blower and flows in the air channel pipe of the heated double-layer partition heat regenerator. The heated high-temperature air enters the air-gas full-premixing pipe and mixes with the gas ejected by the gas nozzle, and then continues to be discharged into the cavity of the porous medium plate burner for full mixing. Because the double-layer partition heat regenerator has very long air and waste gas channels, it provides sufficient heat exchange time and sufficient temperature difference for the normal-temperature air and the high-temperature waste gas when they flow in the pipe, and has a relatively high heat exchange and heat regeneration effect.
[0015] The heat-insulating combustion chamber is equipped with a porous medium plate burner, an ignition pin, and a flameout protection pin. After the ignition device ignites, the mixed combustible gas burns on the surface of the porous medium plate burner, converting the heat energy generated by the combustion into infrared heat radiation that passes through the flat, high-temperature-resistant micro-ceramic glass plate above, effectively transferring the heat energy to the heated cookware. This also increases the overall temperature of the double-walled regenerator. After the exhaust gas temperature drops, it is discharged through the exhaust outlet at the outer end of the double-walled regenerator into the exhaust pipe connected to the outside, completely exhausting the exhaust gas from the kitchen.
[0016] The heat radiation flat environmentally friendly gas stove with a double-layer partition wall heat regenerator of the present invention is provided with a combustion-supporting blower for forced air intake, which provides a larger oxygen supply and can maintain a smaller distance between the porous medium plate burner and the flat high-temperature resistant microcrystalline glass plate, so that the thermal efficiency of infrared heat radiation heating cookware is higher.
[0017] Furthermore, a waste gas catalytic purification device can be installed at the rear end of the waste gas exhaust pipe to treat pollutants such as nitrogen oxides and sulfides produced by combustion, so that various toxic and harmful polluting gases can be completely treated before being discharged to the outdoors, making the indoor and outdoor environment completely pollution-free.
[0018] Some parts of the heat radiation flat environmentally friendly gas stove with a double-layer partition wall heat regenerator of the present invention, such as the ignition needle, flameout protection needle, gas nozzle, combustion-supporting blower, gas air intake solenoid valve, gas regulating valve, igniter, circuit control module, etc., can all adopt standard products available on the market.
[0019] The beneficial effects achieved by the heat radiation flat environmentally friendly gas stove with a double-layer partition wall heat regenerator of the present invention are as follows:
[0020] The present invention discloses a heat radiation flat environmentally friendly gas stove with a double-layer partition wall heat regenerator, which realizes efficient recovery of sensible heat and latent heat of high-temperature waste flue gas and is used to preheat normal temperature air entering the double-layer partition wall heat regenerator, thereby improving the thermal efficiency of the gas stove and reducing gas consumption.
[0021] The present invention is a heat radiation flat environmentally friendly gas stove with a double-layer partition wall heat regenerator, which reduces the exhaust gas temperature and then discharges it to the outside, effectively reducing the thermal pollution caused by high-temperature exhaust gas emissions and effectively reducing the chemical pollution caused by exhaust gas emissions, thereby providing a more comfortable and healthy kitchen cooking environment.
[0022] The combustion-supporting blower provides sufficient excess air coefficient, and the gas is completely burned in a closed environment with sufficient oxygen supply, which effectively improves the combustion efficiency of the fuel, reduces the generation of nitrogen oxides, and saves energy and is environmentally friendly.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described with reference to the accompanying drawings and embodiments. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,and Figure 5 .
[0030] In the description of this application, it should be understood that the terms "upper", "lower", "top surface", "bottom surface" and the like indicate positions or location relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0031] This embodiment works as follows: the main power switch (29) is turned on, and the combustion-supporting blower (30) is started. Under the wind pressure of the combustion-supporting blower (30), the air outside the gas stove passes through the double-layered partition wall type heat exchanger air inlet (19), the double-layered partition wall type heat exchanger air outlet (20), the air-gas full premixing pipe (11), the porous medium plate burner (5), the heat-insulating combustion chamber (4), the smoke hole (8), the double-layered partition wall type heat exchanger exhaust gas inlet (21), the double-layered partition wall type heat exchanger exhaust gas outlet (22), and finally discharged into the outdoor atmosphere through the exhaust gas exhaust pipe (25) connected to the outdoor. The gas regulating valve (15) is opened by the gas regulating knob (16), and the gas enters the air-gas full premixing pipe (11) from the gas nozzle (17), and is fully mixed with the combustion-supporting air entering from the air outlet (20) of the double-layer partition wall type heat regenerator in the air-gas full premixing pipe (11). When the gas regulating valve (15) is opened, the electronic igniter (26) is also started at the same time, igniting the mixed combustible gas ejected from the plate holes of the porous medium plate burner (5), and burning on the surface of the porous medium plate burner (5), converting the heat energy generated by the combustion into infrared heat radiation with strong penetrating ability, which passes through the flat high-temperature resistant microcrystalline glass plate (1) on the upper part of the gas stove, effectively transferring the heat energy so that the cookware absorbs the heat energy and heats the cookware.
[0032] The heat-insulating combustion chamber (4) is fixedly mounted on the gas stove bottom shell (32) by a heat-insulating combustion chamber support (34). The heat-insulating combustion chamber (4) has an opening with an outer flange. When assembled, the outer flange is slightly lower than the bottom surface of the flat high-temperature resistant microcrystalline glass plate (1). The outer wall surface and the bottom of the heat-insulating combustion chamber (4) are fixedly covered with a high-temperature resistant heat-insulating material felt to ensure that heat is not transferred to the stove shell.
[0033] When in use, the bottom of the cookware is placed on the flat high-temperature resistant microcrystalline glass plate (1). To prevent the heat radiation temperature from exceeding the maximum heat-resistant limit temperature of the flat high-temperature resistant microcrystalline glass plate (1), the distance between the bottom surface of the flat high-temperature resistant microcrystalline glass plate (1) and the top surface of the porous medium plate burner (5) is maintained within 15 millimeters. The bottom surface of the high-temperature resistant heat-insulating sealing felt ring (3) is attached to the outer turned-up edge of the upper opening of the heat-insulating combustion chamber (4). The top surface of the high-temperature resistant heat-insulating sealing felt ring (3) is in contact with the flat high-temperature resistant microcrystalline glass plate (1). The high-temperature resistant heat-insulating sealing felt ring (3), the heat-insulating combustion chamber (4), and the flat high-temperature resistant microcrystalline glass plate (1) together form an effective closed isolation between the high-temperature chamber of the cooker and the surrounding air, forming a closed combustion chamber.
[0034] The described flue gas pipe (10) is of a U-shaped pipe structure. One end of the pipe opening is connected to the flue gas hole (8) at the bottom of the heat-insulating combustion chamber (4), and the other end of the pipe opening is connected to the waste gas inlet (21) of the double-layer partition regenerator. The flue gas pipe (10) is arranged at the bottom of the heat-insulating combustion chamber (4). The waste flue gas of the formed closed combustion chamber cannot be discharged through any other channels and can only be discharged into the waste gas inlet (21) of the double-layer partition regenerator through the flue gas hole (8) fixed at the bottom of the heat-insulating combustion chamber (4).
[0035] The described double-layer partition regenerator (18) is made of a metal material with good heat conduction performance and has a rectangular "day" - shaped structure. It is fixedly installed on the bottom shell (32) of the gas stove by the double-layer partition regenerator support column (35). The air and waste gas channels are separated by the middle layer metal plate. The double-layer partition regenerator (18) has a double-channel structure of an upper air channel and a lower waste gas channel. Two end parts of the lower waste gas channel are respectively provided with two holes, namely: the waste gas inlet (21) of the double-layer partition regenerator at the inner ring end of the double-layer partition regenerator (18) and the waste gas outlet (22) of the double-layer partition regenerator at the outer ring end. Two end parts of the upper air channel are respectively provided with two holes, namely: the air inlet (19) of the double-layer partition regenerator at the outer ring end of the double-layer partition regenerator (18) and the air outlet (20) of the double-layer partition regenerator at the inner ring end. Among them, the waste gas inlet (21) of the double-layer partition regenerator is fixedly connected to the flue gas pipe (10), the air outlet (20) of the double-layer partition regenerator is fixedly connected to the air-gas full-premixing pipe (11), the air inlet (19) of the double-layer partition regenerator at the outer ring end is fixedly connected to the air outlet of the combustion air blower (30), and the waste gas outlet (22) of the double-layer partition regenerator at the outer ring end is fixedly connected to the waste gas exhaust pipe (25).
[0036] The high-temperature flue gas flowing in the double-layered partitioned heat exchanger (18) releases heat to the double-layered partitioned heat exchanger (18) as it flows through the exhaust gas passage, causing the overall temperature of the double-layered partitioned heat exchanger (18) to rise. After the temperature of the exhaust gas decreases, it is discharged from the kitchen through the exhaust gas outlet (22) of the double-layered partitioned heat exchanger and the exhaust gas exhaust pipe (25) connected to the outside. The double-layered partitioned heat exchanger (18) of the present invention utilizes the waste heat of the flue gas to efficiently reheat and preheat the air at room temperature, thereby significantly improving the thermal efficiency of the gas stove and reducing gas consumption. Furthermore, the exhaust gas temperature is lowered and then discharged to the outside. This significantly reduces the thermal pollution caused by the high-temperature exhaust gas.
[0037] In the lower exhaust gas channel and the upper air channel inside the double-layer partition wall type regenerator (18), the exhaust gas fluid and the air fluid flow in opposite directions.
[0038] The combustion-supporting blower (30) immediately pumps room-temperature air into the air inlet (19) of the double-layer partition wall type heat exchanger after the main power switch (29) is turned on. When the gas regulating knob (16) is turned on, the electronic igniter (26) ignites the ignition needle (6), and the gas regulating valve (15) opens the gas channel at the same time, and the gas enters the gas nozzle (17) and is ejected. After the gas is ignited and burned, the room-temperature air discharged by the combustion-supporting blower (30) flows in the air channel tube of the heated double-layer partition wall type heat exchanger (18) and is gradually heated. The heated high-temperature air enters the air-gas full premixing tube (11) and mixes with the gas ejected from the gas nozzle (17), and is further discharged into the cavity of the porous medium plate burner (5) for full mixing. The combustion-supporting blower (30) provides sufficient excess air coefficient, and the gas is completely burned in a closed environment with sufficient oxygen supply, effectively improving the combustion efficiency of the fuel, reducing the generation of harmful pollutants such as nitrogen oxides, and saving energy and protecting the environment.
[0039] The gas nozzle (17) is arranged at the full premixing tube gas nozzle interface (14) at the end of the air-gas full premixing tube (11), and one end of the gas supply connecting pipe (31) is connected to the gas nozzle (17) and the other end is connected to the gas regulating valve (15).
[0040] The air-gas full premixing pipe (11) is arranged at the bottom of the heat-insulating combustion chamber (4); the upper full premixing pipe air inlet interface (12) is connected to the double-layer partition wall type regenerator air outlet (20); the full premixing pipe mixed gas discharge interface (13) passes through the bottom of the heat-insulating combustion chamber (4) and is connected to the burner mixed gas inlet (9); the full premixing pipe gas nozzle interface (14) at the side end is installed with a gas nozzle (17).
[0041] The combustion-supporting blower (30), the gas intake solenoid valve (24) and the flameout protection needle (7) of this embodiment are controlled in a linkage manner and are controlled by the circuit control module (27). After the main power switch (29) is turned on, the combustion-supporting blower (30) and the gas intake solenoid valve (24) are started at the same time. If any of the components of the combustion-supporting blower (30) and the flameout protection needle (7) stops working, the gas intake solenoid valve (24) immediately stops supplying power, shuts off the gas intake, and eliminates safety hazards.
[0042] The flameout protection needle (7) device is a known technology and will not be described in this embodiment.
[0043] The surface of the double-layered wall-type heat regenerator (18) is covered with high-temperature resistant fireproof heat-insulating material to ensure that heat is not transferred to the gas stove shell.
[0044] The gas stove upper shell (2) is a rectangular body with a circular hole in the middle of its top surface. The diameter of the circular hole is larger than that of the heat-insulating combustion chamber (4) and is a channel for heat radiation to transmit heat energy through the top flat high-temperature resistant microcrystalline glass plate (1).
[0045] The flat high-temperature resistant microcrystalline glass plate (1) is a rectangular plate with the same length and width as the gas stove upper shell (2), and is used for carrying cookware.
[0046] The porous medium plate burner (5) is a cylindrical upper opening structure with a hollow tube in the middle. The porous medium plate is arranged at the upper opening. The bottom surface of the porous medium plate burner (5) is provided with a burner mixed gas inlet (9). The ignition needle (6) and the flameout protection needle (7) are arranged on the top of the porous medium plate burner (5). The line of the ignition needle (6) and the line of the flameout protection needle (7) pass through the hollow tube in the middle. The porous medium plate burner (5) is arranged in the heat-insulating combustion chamber (4).
[0047] One end of the exhaust gas exhaust pipe (25) is connected to the exhaust gas outlet (22) of the double-layer partition wall heat regenerator, and the other end is connected to the outside. The exhaust gas is completely discharged from the kitchen, thereby providing a more comfortable and healthy kitchen cooking environment.
[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by ordinary technicians in this technical field within the technical scope described in the present invention should be covered by the scope of protection of the present invention.
