Description

Technical Field

[0001] The invention relates to the field of stoves, in particular to a liquid fuel stove. Background Art

[0002] Liquid fuel stoves refer to cooking stoves that use liquid fuel as energy and are directly heated by fire. Liquid fuels have a relatively high ignition point and require a relatively high temperature to ignite, so they are safer, but they also bring a problem, that is, ignition is difficult, so it is necessary to preheat the liquid fuel to be burned to a relatively high temperature for ignition, so that it can be ignited more conveniently and burn more fully, so an electrical device for heating the fuel is needed. However, in order to use the electric heating rod in the heater safely, a lot of liquid fuel is needed to cool the heating rod before heating, otherwise the heating rod will dry burn and burn it. During the heating process, the volume of the liquid fuel increases with the increase of the heating temperature, but the volume of the corresponding container is unchanged, so the liquid fuel will overflow from the liquid fuel atomizing nozzle hole to the outside and everywhere, so a shower tray with a concave oil collecting trough on the surface is needed to store the overflowed liquid fuel and make it flow back to the fuel tank through the oil return hole and the oil return pipe. Then the purpose of beautifying the environment is achieved, while also reducing energy waste and safety. At the same time, since combustion requires sufficient oxygen, a ventilation duct is required. The flame light will leak down from this ventilation duct, causing the loss of radiant heat, so a shower tray is also needed to reflect the leaked light back and heat the combustion air coming in from the ventilation duct twice to achieve the purpose of reducing consumption. Summary of the invention

[0003] The present invention proposes a reflective shower tray liquid fuel stove, which solves the energy-saving and environmental protection problems caused by oil and light leakage due to the need for heating and ventilation when the liquid fuel stove is in use. Therefore, the reflective shower tray technology is needed to solve the above problems.

[0004] The technical solution of the present invention is achieved in this way:

[0005] The present invention proposes a reflective shower tray liquid fuel stove, which includes an oil pipeline, a regulating valve, an electric heating rod, a heater, a liquid fuel atomizing nozzle, an electric pulse igniter, an igniter, a furnace throat, a reflective shower tray, a concave oil collecting groove arranged on the surface of the reflective shower tray, an oil return hole of the concave oil collecting groove on the reflective shower tray, an oil return pipe, and a fuel tank. The reflective shower tray is installed at the lowest end of the heater, and all leaked oil is stored and collected as much as possible, and flows back to the fuel tank through the oil return hole and the oil return pipe, while not affecting the flow of preheated air, and can also reflect the leaked flame light back through the reflective shower tray, and preheat the preheated air twice in succession, so as to reduce energy loss and improve the environment and safety.

[0006] Furthermore, the preheated air is the air that must be involved in the combustion of the fuel when the flame burns, which is called combustion-supporting air. It is achieved by utilizing the high air velocity at the throat and the pressure is lower than the atmospheric pressure. The air in the atmosphere is squeezed and drawn in under the action of this pressure difference and participates in the combustion. In order to ensure the air volume for combustion, a certain flow area is required, so the throat is a relatively large hollow position.

[0007] Furthermore, when the burning flame hits the flame divider (the flame divider is to ensure that the burning speed of the flame is equal to the flow speed of the fuel, so as to solve the problem of flame failure and ensure that the fuel can burn normally), some of the flame light will (leak) reverse through the hollow throat and perform the first convection heat release to the preheated air squeezed in. After heat release, it will leave the combustion system, which is a heat energy loss in the form of heat radiation.

[0008] Furthermore, when the leakage light radiation is at the lowest position of the heater, it is blocked by the reflective shower plate, and then reflected back to the combustion system by the reflective shower plate in the form of reflected light, and the preheated air is preheated for the second time. Therefore, the reflective shower plate significantly improves the thermal efficiency of the stove, reduces the thermal pollution around the stove, and improves the surrounding environment of the stove.

[0009] Furthermore, in order to ensure that the heater does not dry burn, there must be enough liquid fuel around the electric heating rod to cool it, and the regulating valve must be closed under the condition of sufficient liquid fuel. When the electric heating rod is turned on to heat the liquid fuel, the volume of the heated liquid fuel increases, and the regulating valve is closed, that is, the volume in the system remains unchanged, and liquid fuel overflows from the liquid fuel atomizing nozzle hole to the outside floor at all times, and the floor is full of liquid fuel, which is very unsafe. At this time, a reflective shower tray is installed to store and collect all the overflowing fuel oil as much as possible, and return it to the fuel tank through the guide hole and the return oil pipe, which plays a role in energy saving, safety and environmental protection.

[0010] Beneficial effects of the present invention:

[0011] In summary, the reflective shower tray liquid fuel stove of the present invention can preheat the combustion-supporting air and reduce light leakage loss, thereby reducing both the loss of radiation energy and the overflow loss of fuel, thereby protecting the environment and working conditions and improving the thermal efficiency of the stove.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments only show a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0015] Example

[0016] Referring to the figure of the reflective shower tray liquid fuel stove, first open the regulating valve to make the liquid fuel fill the entire heater, and when there is a dotted fuel oil overflowing in the liquid fuel atomizing nozzle, close the regulating valve, start the electric heating rod to heat the fuel oil, and when it is heated to the ignition temperature of the fuel oil, press the electric pulse igniter to make the electric pulse ignition have continuous electric sparks, and then open the regulating valve, so that the liquid fuel heated to the ignition temperature is atomized by the liquid fuel atomizing nozzle, and the fuel oil is ignited by the continuous ignition sparks. In this process, some fuel overflows from the atomizing nozzle, and flows into the reflective shower tray under the action of the earth's gravity, and then flows back to the fuel tank through the reflux hole and the return oil pipe to achieve the purpose of energy saving and environmental protection. Due to the presence of the ignition divider, the flame speed is equal to the fuel movement speed. At this time, some flame rays radiate in the opposite direction under the action of the ignition divider. Since the throat part of the stove head is hollow, these flame rays will leak through this throat part and radiate into the reflective shower tray, but reflect back through the reflective shower tray. Since the airflow velocity is the highest and the pressure is the lowest at the throat of the furnace head, which is lower than the atmospheric pressure, a large amount of air is squeezed in under the action of atmospheric pressure. The reverse flame light performs the first convection heat release on the compressed air by using the convection heat release method. The preheated air is sucked into the flame under the action of the flame entrainment and participates in the combustion of the flame. At the same time, the reverse flame light leaked under the action of the reflective shower tray is reflected back by the reflective shower tray and performs convection heat release on the squeezed air again, so as to improve the thermal efficiency of the stove and achieve the purpose of energy saving and environmental protection.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
