Description

Technical Field

[0001] The invention relates to a gas and electricity dual-purpose multifunctional stove and a use method thereof, belonging to the field of stoves. Background Art

[0002] At present, stoves are used more and more widely. They can not only be used for heating, but also for boiling water and cooking to meet daily life needs. There are many stoves on the market, including stoves that use biomass fuel as energy, stoves that use electricity as energy, and stoves that use gas as energy, but basically each type of stove uses a relatively single energy source and cannot meet a wide range of life uses. Summary of the invention

[0003] The purpose of the present invention is to overcome the single energy utilization of stoves. It can use gas (natural gas, liquefied petroleum gas, biogas, etc.) and electricity for heating alone, or use a mixture of the two energy sources for heating. The structure adds a waste heat gas heating table design compared to traditional stoves, and has multiple rows of air inlet holes, which promotes the full combustion of combustible gas, improves energy utilization, and protects the environment. The stove is simple to use, has multiple functions, and has a good promotion prospect.

[0004] In order to solve the above technical problems, the present invention proposes the following technical solutions: a multifunctional gas and electric dual-purpose stove, which includes a base, a furnace wall shell is fixedly installed on the top of the base, a furnace chamber is arranged inside the furnace wall shell, a table top is supported on the top of the furnace wall shell, a turntable is rotatably supported and installed at the center of the table top through an annular slide rail, and a gas disc is installed at the bottom of the furnace chamber; a plurality of electric heating tubes are vertically and evenly installed on the periphery of the furnace wall shell and between the base and the table top.

[0005] The electric heating tubes are evenly arranged on the base at intervals of 90 degrees and close to the furnace wall shell.

[0006] A temperature sensor is fixed on the inner wall of the furnace wall shell.

[0007] A gas-electric dual-purpose heating plate is installed at the center of the tabletop; both the gas-electric dual-purpose heating plate and the gas plate can use natural gas, liquefied petroleum gas and biogas.

[0008] The upper periphery of the gas-electric dual-purpose heating plate is provided with ventilation holes, the ventilation holes are communicated with the interlayer of the desktop, and the periphery of the desktop is provided with a detection sensor for detecting gas leakage.

[0009] A cavity is left between the furnace wall shell and the furnace, the entire furnace is provided with an annular air inlet hole, and furnace vent holes are provided on the upper and lower parts of the furnace wall shell.

[0010] The furnace wall shell and the top cavity of the furnace are connected with the interlayer of the desktop through an air inlet, and the side wall of the interlayer of the desktop is connected with an exhaust pipe.

[0011] A micro-control computer board is installed on the top of the desktop. The micro-control computer board is connected to the electric heating tube and the gas-electric dual-purpose heating plate, and controls the opening and closing of the controller.

[0012] An air guide pipe is arranged on the base, and the air guide pipe is communicated with the furnace wall shell.

[0013] The method for using any one of the multifunctional gas and electric dual-purpose stoves comprises the following steps:

[0014] Step 1: Introduce gas into the furnace shell through the gas guide pipe;

[0015] Step 2: Start the gas plate, burn the gas through the gas plate, and then generate gas flame inside the furnace to heat the stove;

[0016] Step 3: During the initial heating, the temperature in the furnace cannot be raised immediately. At this time, the electric heating tube is used for auxiliary heating. The output power of the electric heating tube is controlled by the temperature sensor temperature measurement feedback to achieve the effect of temperature compensation.

[0017] Step 4: When cooking or heating the hot pot during a meal, start the gas-electric dual-purpose heating plate, and select electric heating or gas heating to heat and cook the cookware placed on the gas-electric dual-purpose heating plate;

[0018] Step 5: During the combustion process, air enters the furnace through the air inlet holes of the furnace wall shell, promoting the complete combustion of the combustible gas on the gas disk. The heat generated is transferred to the furnace wall for heating. The exhaust gas generated has waste heat and enters the desktop interlayer through the cavity between the furnace and the furnace wall shell through the air inlet duct to preheat the desktop.

[0019] The present invention has the following beneficial effects:

[0020] 1. The gas-electric dual-purpose multifunctional stove of the present invention can be heated by gas and electricity alone, or by a mixture of the two energy sources. As long as there is one energy source, the stove can work normally, thereby improving the energy adaptability of the stove.

[0021] 2. When the gas leaks accidentally, the gas leak detection sensor will automatically alarm, thereby improving the safety performance of the stove during use.

[0022] 3. For gas-electric dual-purpose multifunctional stoves, mixed heating is when the gas fuel begins to burn in the furnace, the temperature often cannot be raised immediately. At this time, electric heating tubes can be used for auxiliary heating. The output power of the electric heating tubes can be controlled through temperature sensor temperature measurement feedback to achieve the effect of temperature compensation.

[0023] 4. The gas-electric dual-purpose multifunctional stove can be heated by a single energy source, and can use gas fuel alone or electricity alone. The electric heating module is divided into two parts, one is the electric heating tube used for heating, which is evenly arranged on the base at intervals of 90 degrees, close to the stove wall. This design allows the electric heating tube to be as close to the heater as possible, enhances the heating effect, saves electricity, and can better maintain independence from the gas heating area without interfering with each other; the other is the desktop heating area, which is heated by the gas-electric dual-purpose heating plate and the electric heating plate. The heating area can be used alone for cooking food or heating hot pot during meals, meeting multiple uses in life.

[0024] 5. A cavity is left between the furnace and the furnace wall shell. The furnace has an annular air inlet hole throughout its body. Air inlets are opened at the upper and lower parts of the furnace wall shell. Air can enter the furnace through the air inlet holes of the furnace wall shell to promote the full combustion of the combustible gas on the gas disk. The heat generated is conducted to the furnace wall for heating. The exhaust gas generated has waste heat, which enters the desktop cavity through the air inlet duct through the cavity between the furnace and the furnace wall shell to preheat the desktop, thereby increasing the heat dissipation area of ​​the stove, improving the utilization of waste heat, and enhancing the heating effect of the stove.

[0025] 6. The tabletop has a turntable, and there is an annular slide rail on the tabletop, so that the turntable can rotate on the tabletop, so that the stove has the function of a dining table and has strong practicality in life.

[0026] 7. The exhaust gas after combustion is discharged through the flue of the exhaust pipe. When the exhaust gas is discharged, the air next to the exhaust pipe is heated. The heat emitted can be used for heating, which improves the utilization rate of energy.

[0027] 8. It has a micro-control computer board, combined with a temperature sensor, which can feedback control the furnace temperature, can control the required heating temperature to the maximum extent, can meet the user's various set temperatures, and is easy to use.
