Description
Technical Field
[0001] This utility model relates to the technical field of kitchen equipment, and in particular to a fuel vaporization stove with flameout protection function. Background Technology
[0002] Currently, fuel gasification furnaces convert liquid fuel oil into gas for combustion, resulting in more complete combustion. These furnaces have nozzles at the bottom that spray the liquid fuel oil into a mist onto the outer shell of the vaporization core for combustion. However, these fuel gasification furnaces are not fully functional, lacking features such as flameout protection and low water level protection, which can easily lead to safety accidents. Therefore, existing fuel gasification furnaces are not fully functional and are not safe to use. Utility Model Content
[0003] The purpose of this utility model is to provide a fuel gasification stove with flameout protection function that is simple in structure and safe to use.
[0004] The purpose of this utility model is achieved as follows:
[0005] A fuel oil vaporization stove with flameout protection includes a burner head, an oil pump, an oil inlet pipe, an igniter, an exhaust fan, a control board, and an oil vaporizer. The burner head is equipped with an ignition needle and a flame detection needle, and the igniter is electrically connected to the ignition needle. The oil pump is located on the oil inlet pipe, one end of which is connected to the oil inlet of the oil vaporizer, and the steam outlet of the oil vaporizer is connected to the burner head. The oil vaporizer is equipped with a heating element and a temperature probe. The control board is electrically connected to the oil pump, exhaust fan, oil vaporizer, igniter, water level probe, flame detection needle, heating element, and temperature probe. This invention uses the flame detection needle to sense the flame, thus achieving flameout protection and ignition failure protection. It also uses the temperature probe to detect the temperature inside the oil vaporizer, thus achieving high-temperature protection and low-temperature protection. Due to the above design, this fuel oil vaporization stove has more complete functions and is safer and more convenient to use.
[0006] When the flame detector needle of this invention fails to detect the flame on the burner head, it sends a signal to the control board, which then controls the oil pump to stop supplying oil, thereby achieving functions such as flame detection, accidental flameout protection, and ignition failure protection. For example, if the flame on the burner head is extinguished by liquids such as soup or water, or if the ignition needle fails to ignite, oil mist will continue to be emitted from the burner head, posing a safety hazard. Therefore, this invention is safer to use. When the temperature probe of this invention detects that the temperature inside the oil vaporizer has reached the set temperature, it sends a signal to the control board. At this time, the oil inside the oil vaporizer has vaporized and atomized, and the user can control the ignition needle to ignite it.
[0007] The present invention can be further improved in the following ways.
[0008] The control panel is equipped with a display screen, a fire control knob, and a start button. The display screen shows the temperature of the fuel. The fire control knob adjusts the fuel supply by adjusting the power of the fuel pump, thereby adjusting the size of the flame on the burner. The start button controls the ignition needle to ignite the fuel.
[0009] This invention also includes a water level probe, which is electrically connected to the control board. The water level probe is used to detect the water level in the cookware, making it suitable for appliances such as steamers. When the probe detects that the water level in the cookware is too low, the control board stops the oil pump from supplying oil, preventing the burner from igniting and thus achieving dry-burn protection. After the cookware is filled with water, the water level probe sends a signal to the control board, which then controls the oil pump to supply oil, and the burner reignites.
[0010] This utility model also includes a fuel storage tank, and the other end of the fuel inlet pipeline is connected to the fuel storage tank.
[0011] This utility model also includes a furnace chamber, with the furnace head located inside the furnace chamber and the exhaust fan located on the furnace chamber, thereby facilitating the exhaust fan to expel the oil fumes into the room.
[0012] The temperature probe is detachably mounted on the oil vaporizer, making maintenance and replacement convenient.
[0013] The temperature probe is threaded onto one end of the oil vaporizer for easy maintenance and replacement.
[0014] The temperature probe is a thermocouple.
[0015] The oil pump is an electromagnetic pump.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention uses a flame detector needle to sense the flame, thus achieving flameout protection and ignition failure protection. It also uses a temperature probe to detect the temperature inside the oil vaporizer, thus achieving high-temperature protection and low-temperature protection. Finally, it uses a water level probe to detect the water level, thus achieving dry-burning protection. Due to these solutions, this fuel oil vaporizer is more fully functional and safer and more convenient to use. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of the structure of a fuel gasification stove with flameout protection function according to Embodiment 1 of this utility model. Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Example 1, as Figure 1 As shown, a fuel gasification stove with flameout protection function includes a furnace 13, a burner head 1, an oil pump 3, an oil inlet pipe 14, an igniter 12, a water level probe 7, an exhaust fan 11, a fuel storage tank 4, a control board 6, and an oil vaporizer 2. The burner head 1 is equipped with an ignition needle 10 and a flame detection needle 9. The igniter 12 is electrically connected to the ignition needle 10. The oil pump 3 is located on the oil inlet pipe 14. One end of the oil inlet pipe 14 is connected to the oil inlet end of the oil vaporizer 2. The steam outlet end of the oil vaporizer 2 is connected to the burner head 1. The oil vaporizer 2 is equipped with a heating element 21 and a temperature probe 22. The control board 6 is electrically connected to the oil pump 3, the exhaust fan 11, the oil vaporizer 2, the igniter 12, the flame detection needle 9, the heating element 21, and the temperature probe 22. When the flame detection needle 9 of this invention cannot detect the flame of the burner head 1, it sends a signal to the control board 6, and the control board 6 controls the oil pump 3 to stop supplying oil, thereby realizing the functions of flame detection, accidental flameout protection, and ignition failure protection.
[0021] When the temperature probe 22 of this invention detects that the temperature inside the oil vaporizer 2 has reached the set temperature, it sends a signal to the control board 6. At this time, the oil inside the oil vaporizer 2 has vaporized, and the control board 6 controls the ignition needle 10 to ignite. The furnace body of this invention is prior art and will not be described in detail here.
[0022] This is a more specific technical solution of the present invention.
[0023] The control panel 6 is equipped with a display screen 61, a firepower adjustment knob 62, and a start button 63. The display screen shows the temperature of the fuel, the firepower adjustment knob adjusts the fuel supply by adjusting the power of the fuel pump, thereby adjusting the flame size of the burner, and the start button controls the ignition needle to ignite the fuel.
[0024] The other end of the oil inlet pipe 14 is connected to the fuel storage tank 4.
[0025] The furnace head 1 is located inside the furnace chamber 13, and the exhaust fan 11 is located on the furnace chamber 13.
[0026] Temperature probe 22 is detachably mounted on oil vaporizer 2, which facilitates maintenance and replacement.
[0027] Temperature probe 22 is threaded to one end of oil vaporizer 2, which facilitates maintenance and replacement.
[0028] Temperature probe 22 is a thermocouple.
[0029] The control board 6 is electrically connected to the water level probe 7, which is used to detect the water level in the pot, thus adapting to some appliances such as steamers. When the water level probe 7 detects that the water level in the pot is too low, the control board 6 controls the oil pump 3 to stop supplying oil, and the burner 1 does not burn. After the user adds water to the pot 8, the water level probe 7 sends a signal to the control board 6, and the control board 6 controls the oil pump 3 to supply oil, and the burner 1 reignites.
[0030] Oil pump 3 is an electromagnetic pump.
[0031] The working principle of this utility model is as follows:
[0032] When this invention starts working, the control board 6 controls the heating element 21 inside the vaporizer 2 to begin heating, the oil pump 3 starts pumping oil, and the fuel in the fuel storage tank 4 enters the oil inlet pipe 14, then enters the vaporizer 2. The heating element 21 begins heating the oil, and the temperature inside the vaporizer 2 gradually rises until it reaches the vaporization temperature of the fuel. The fuel turns into oil mist, which is then delivered to the burner head 1. The user then presses the start button 63, and the control board 6 controls the ignition needle 10 to ignite the fuel. The burner head 1 begins to burn. The user can adjust the flame size by rotating the flame adjustment knob and adjusting the power of the oil pump 3. During the burning process in the burner head 1, the water level probe 7 monitors the water level in the pot 8 in real time to prevent dry burning. The temperature probe of this invention monitors the temperature inside the vaporizer in real time to prevent fires caused by overheating. When the temperature inside the vaporizer is too high, the temperature probe 22 sends a signal to the control board, which then controls the oil pump 3 to stop supplying oil. Conversely, when the temperature inside the carburetor is low, the condensed fuel cannot pass smoothly through the fuel pump, resulting in insufficient fuel supply.
[0033] A lack of fuel supply or interruption can cause ignition failure, incomplete combustion, or accidental flameout. Temperature probe.
[0034] 22 will send a signal to the control board, which will then control oil pump 3 to stop supplying oil.
