Description

Technical Field

[0001] The utility model relates to the technical field of vegetable oil stoves, in particular to a novel vegetable oil stove. Background Art

[0002] As a clean and environmentally friendly fuel, vegetable oil is relatively cheaper than traditional methanol fuel and has certain advantages in terms of cost of use. Therefore, using vegetable oil as a fuel for household stoves is a common alternative. However, due to the characteristics of vegetable oil being difficult to ignite and having high flash point, it is not easy to ignite when ignited, which has certain limitations.

[0003] In order to solve the above technical problems, stoves using vegetable oil as fuel have appeared on the market. For example, authorization announcement number CN220169505U discloses a vegetable oil stove device, which specifically discloses: a burner, an oil storage mechanism and an oil supply assembly, the burner is connected to the oil supply assembly, the oil supply assembly is connected to the oil storage mechanism, and the burner is also equipped with a blowing assembly and an ignition assembly; the oil supply assembly includes a three-way joint, the two ports of the three-way joint are respectively connected to a first oil pump and a second oil pump, the port of the three-way joint away from the first oil pump and the second oil pump is connected to the burner through a first copper tube, the oil inlet end of the first oil pump is connected to a first oil inlet pipe, and the oil inlet end of the second oil pump is connected to a second oil inlet pipe; the first oil inlet pipe and the second oil inlet pipe are both connected to the oil storage mechanism; the blowing assembly, the ignition assembly, the first oil pump, and the second oil pump are all electrically connected to the same control computer through wires.

[0004] Although the above-mentioned plant stove device solves the problem of ignition limitation, there are still some areas that need to be improved. For example, in order to solve the problem of ignition limitation, it pre-stores two different fuels, vegetable oil and methanol, in the oil storage mechanism, and connects the burner head through two oil inlet pipes, and then uses the first oil pump and the second oil pump to transport methanol and vegetable oil to the burner head, so as to achieve ignition through fuel transition; however, in order to transport two different fuels, it is necessary to set up two oil inlet pipes, and respectively set up oil pumps on the oil inlet pipes. This oil delivery structure is relatively complicated, and the method of setting up multiple oil pumps also increases the cost of the stove accordingly; in addition, for home cooking, it is often necessary to always have two fuels to achieve the purpose of convenient ignition, which is not convenient enough when used.

[0005] Therefore, it is necessary to further improve the prior art. Utility Model Content

[0031] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the utility model.

[0032] like Figure 1-Figure 2 As shown, a novel vegetable oil stove comprises: an inner wind furnace 1, an oil tank 2, a fan 3 and a controller 4;

[0033] like Figure 2 As shown, the inner wind furnace 1 includes a furnace 11 and an inner tank 12 arranged in the furnace 11 and having an open top, a cavity 13 is formed between the furnace 11 and the inner tank 12, and a ventilation hole 14 connected to the cavity 14 is provided on the side wall of the inner tank 12; specifically, a plurality of ventilation holes 14 are provided, and the plurality of ventilation holes 14 are evenly distributed on the side wall of the inner tank 12, so that the airflow transported from the outside can enter the inner tank 12 from multiple angles.

[0034] like Figure 2 As shown, a heating module 5 is further provided at the bottom of the furnace 11, and a thermocouple sensor 6 is provided at the bottom of the heating module 5. Through the above arrangement, the heating module 5 can heat the vegetable oil flowing into the inner pot 12, and the thermocouple sensor 6 can monitor the temperature of the heated vegetable oil in real time. In this embodiment, when the temperature of the heated vegetable oil reaches 200 degrees, the thermocouple sensor 6 will automatically shut down.

[0035] like Figure 2 As shown, an ignition device 7 is provided on the inner tank 12; specifically, the ignition device 7 is arranged in the inner tank 12 and parallel to the upper edge of the oil delivery pipe 21. Through the above arrangement, the ignition device 7 can generate an open flame to ignite the vegetable oil flowing into the inner tank 12.

[0036] like Figure 1 As shown, the oil tank 2 is connected to the inner tank 12 through an oil delivery pipe 21, and an oil pump 23, a liquid storage cup 25 and a solenoid valve 26 are sequentially provided on the oil delivery pipe 21 in the direction of the inner tank 12; a return oil pipe 22 connected to the oil tank 2 is provided on the oil delivery pipe 21, and a pressure reflux valve 24 is provided on the return oil pipe 22; in this embodiment, the oil pump 23 is used to extract the vegetable oil in the oil tank 2 and transport it to the inner tank 12 through the oil delivery pipe 21; when the liquid level in the liquid storage cup 25 reaches the specified position of the liquid storage cup 25, the pressure reflux valve 24 will be opened under the influence of the pressure of the oil pump 23, so that the vegetable oil in the liquid storage cup 25 will flow back into the oil tank through the pressure reflux valve 24, thereby forming a situation in which the vegetable oil flows back to the oil tank 2 without stopping the oil pump 23.

[0037] like Figure 1As shown, the controller 4 is electrically connected to the oil pump 23, the solenoid valve 26, the fan 3 and the heating module 5 respectively; the controller 4 is also provided with a fan speed regulator 43 for controlling the speed of the fan 3. In this embodiment, the controller 4 is provided with a power switch 41, the controller 4 is connected to an external power supply 42, and the controller 4 is electrically connected to the oil pump 23, the solenoid valve 26, the fan 3 and the heating module 5 respectively through wires, so as to realize automatic control of the oil pump 23, the solenoid valve 26, the fan 3 and the heating module 5. Among them, the fan 43 speed regulator can control the size of the wind delivered to the cavity 13, so as to realize effective control of the firepower.

[0038] like Figure 2 As shown, the oil delivery pipe 21 is arranged at the lower end of the inner liner 12, and the ventilation hole 14 is relatively arranged above the oil delivery pipe 21, so that the vegetable oil flowing into the inner liner 12 through the oil delivery pipe 21 is not easy to flow back into the cavity 13.

In this embodiment, since the ventilation pipe 31 is arranged at the lower end of the furnace 11, and the ventilation hole 14 is relatively arranged above the ventilation pipe 31, when the airflow blown by the fan 3 flows into the cavity 13 from the bottom, the airflow can rise and be directly blown into the inner tank 12 through the ventilation hole 14 located above it.

[0040] Combination Figure 1-Figure 2 , the specific use principle of the utility model is introduced below to facilitate understanding of the utility model:

[0041] First, connect the controller to an external power supply, turn on the power switch, and then open the solenoid valve. The controller controls the oil pump to transfer the vegetable oil in the oil tank to the inner tank through the oil pipe. After the vegetable oil is transferred and passes through the liquid storage cup, the liquid storage cup controls the flow of the transferred vegetable oil and distributes it to the inner tank according to a predetermined flow rate. When the vegetable oil flows into the liquid storage cup and rises to a specified position in the liquid storage cup, such as the highest point, due to the pressure after the oil pump transfers the oil, the height positioning valve (not shown in the figure) set in the liquid storage cup will open, and the corresponding pipeline reflux valve will open synchronously, so that when the oil pump is not shut down, the vegetable oil in the liquid storage cup will flow back to the oil tank through the oil return pipe, thereby realizing circulating oil supply between the oil pump and the oil tank.

[0042] After the vegetable oil is delivered to the inner tank, the controller will control the heating module to heat the vegetable oil delivered to the inner tank. At the same time, the thermocouple sensor monitors the heating temperature in real time. When the temperature of the heated vegetable oil reaches 180 degrees, the controller will control the fan to blow air into the cavity through the ventilation pipe, and the air flow will then flow into the interior of the inner tank through the ventilation holes. When the temperature of the heated vegetable oil reaches 200 degrees, the thermocouple sensor stops working. At this time, the controller controls the ignition device to ignite the vegetable oil.

[0043] When the fan blows air into the cavity, the controller can adjust the speed of the air flow delivered to the cavity through the fan speed regulator. When the air flow speed increases, the combustion speed of the vegetable oil will be accelerated, and accordingly, the combustion power will also increase; when the air flow speed decreases, the combustion speed of the vegetable oil will be slowed down, and accordingly, the combustion power will also decrease.

[0044] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
