Technical Field
[0001] The present application relates to the technical field of oil pan fire prevention devices, and in particular to a back kitchen frying pan fire prevention device. Background Art
[0002] Fried foods are widely loved by people because of their crispy taste, fragrant aroma and appetite-stimulating properties. When frying food in an oil pan, due to the high frying temperature, it is easy for an open flame to appear when the oil pan is used. If the open flame generated by the oil pan during cooking is not extinguished in time, it is not only easy to threaten the safety of the cooking staff, but also easy to ignite other objects nearby, causing a larger fire and causing more property losses. Summary of the invention
[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a back-kitchen frying stove device to solve the problem that the frying temperature is high and an open flame is likely to occur when the oil pan is used. If the open flame generated by the oil pan during cooking is not extinguished in time, it is not only easy to threaten the safety of the cooking personnel, but also easy to ignite other objects nearby and cause a larger fire.
[0004] According to an embodiment of the present application, a back-kitchen frying and fire-proof stove device includes: a shell body portion, a heating pot portion and a fire-proof covering portion.
[0005] The main body of the housing includes a frame shell, a microcomputer operation screen and a flame sensor, wherein the microcomputer operation screen is installed on the front side of the frame shell, the flame sensor is arranged on the upper rear side of the frame shell, and both sides of the upper side of the frame shell are provided with openings; The heating pot part includes a pot body and a heating assembly, the pot body is installed inside the mounting opening at the top of the frame shell, and the heating assembly is arranged at the bottom of the pot body; The fireproof covering part comprises a pot cover, a support arm, a handle, a transmission shaft, a support, a plug rod, a limit block and an electromagnet with a hole-shaped structure in the middle. Two groups of the supports are respectively fixed on the top of the frame shell located on the rear side of the pot body, the transmission shaft rotatably passes through the support, the bottom end of the support arm and the end of the transmission shaft are fixedly arranged, and the handle is installed between the top ends of the two support arms, the pot cover is located between the two support arms, shaft rods are arranged on both sides of the pot cover, the shaft rods are rotatably arranged with the support arms, the bottom end of the plug rod movably passes through the through opening, and the top end of the plug rod is rotatably arranged with the side of the pot cover, the limit block is located inside the frame shell, and the limit block is fixed at the bottom end of the plug rod, the electromagnet is installed inside the frame shell and is located below the through opening, the plug rod movably passes through the electromagnet, and the electromagnet and the limit block are magnetically adsorbed and matched.
[0006] Pull the handle upwards, and the support arm and the plug rod will drive the pot lid closed on the pot body to move upwards, until the limit block at the bottom of the plug rod contacts the electromagnet, and the electromagnet will magnetically absorb and fix the limit block, so that the pot lid is positioned after being flipped upwards. The heating component heats the oil inside the pot body, and the food can be fried and cooked by putting it into the pot body. When a flame appears on the pot body, the flame sensor can detect the flame on the pot body, and the electromagnet will be powered off through the cooperation of the microcomputer operation screen. After the power is off, the electromagnet loses its magnetic attraction to the limit block, and resets the lid to close on the pot body under the action of gravity. At this time, the oil in the pot body is isolated from the external air, and the flame inside the pot body will automatically extinguish, which not only plays a good fire prevention role, but also plays a good protection role for the safety of the cook.
[0007] After the electromagnet in the above-mentioned back-kitchen frying anti-fire stove device is powered off, the pot cover falls down and closes on the pot body by gravity. Due to the heavy weight of the pot cover as a whole and the fast speed of moving downward to close, the cooks may be easily injured while cooking. In addition, the impact caused by the fast falling of the pot cover may easily cause damage to the device components.
[0008] The back-kitchen frying and fire-proof stove device also includes a covering buffer part, which includes a pillar, a sleeve with an arc structure, a sleeve rod with an arc structure, a connecting column and a piston. The bottom end of the pillar is fixedly connected to the top of the frame shell, the sleeve is fixed above the pillar, the connecting column connects the transmission shaft and the sleeve rod, the piston is arranged at the bottom end of the sleeve rod, and the piston is located inside the sleeve, the rotating transmission shaft drives the piston to move inside the sleeve through the connecting column and the sleeve rod, and an exhaust hole is arranged at the top of the sleeve.
[0009] When the electromagnet is powered off and the pot cover moves downward under the action of gravity, the rotating transmission shaft will drive the sleeve rod to rotate around the axial position of the transmission shaft through the connecting column, and the rotating sleeve rod will drive the piston at the end to move inside the sleeve to squeeze the air inside the sleeve, and the air inside the sleeve will eventually be slowly discharged from the exhaust hole. In the process of the piston squeezing the air inside the sleeve, the over-pressure air inside the sleeve will slow down the rotation speed of the transmission shaft through the sleeve rod and the connecting column, that is, there is a certain buffering effect when the pot cover falls down and closes. The pot cover slowly closes on the pot body. The closed pot cover will block the flame inside the pot body and play a good fire prevention role. This design can effectively slow down the speed of the pot cover moving down, and prevent the cook from being accidentally injured by the falling pot cover when the pot cover suddenly falls, and the pot cover can effectively reduce the impact between the pot cover and the pot body after closing the pot body through the buffer cover, and also play a good protective role for the components in the device.
[0010] In some embodiments of the present application, the interior of the support is a hollow structure, and the covering buffer portion is arranged inside the support.
[0011] In some embodiments of the present application, the heating assembly includes an electric heating tube, and the electric heating tube is installed at the bottom of the pot body.
[0012] In some embodiments of the present application, the heating assembly further includes a shield shell, which is located outside the electric heating tube and is fixed to the bottom of the pot body.
[0013] In some embodiments of the present application, the frame housing further includes a start switch, the start switch is electrically connected to the microcomputer operation screen, and the microcomputer operation screen is electrically connected to the flame sensor and the electromagnet.
[0014] In some embodiments of the present application, the shell body also includes a fuse, which is connected to the start switch and the microcomputer operation screen.
[0015] In some embodiments of the present application, the shell body also includes a working indicator light, and the working indicator light is connected to the power supply through the start switch.
[0016] In some embodiments of the present application, the heating pot part also includes a temperature sensor, and the temperature sensor and the electric heating tube are electrically connected to the microcomputer operation screen respectively.
[0017] In some embodiments of the present application, the handle is rotatably connected to the support arm, and a rubber sleeve is provided on the outside of the handle.
[0018] Although the above-mentioned back-kitchen frying anti-fire stove device can extinguish the flame by closing the pot cover over the pot body, the oil temperature inside the pot body is too hot. When the pot cover is opened, the oil inside the pot body may reignite due to the high oil temperature, which may easily cause injuries to the cook.
[0019] The back-kitchen frying and fire-proof stove device also includes a heat-conducting and heat-dissipating part, which includes a heat-conducting pipe, a heat sink and a heat-dissipating fan. The pot cover includes a box body and a box cover. The shaft is connected to the side of the box body. The side of the box body is provided with an air inlet hole. The box cover is covered on the top of the box body, and the heat-dissipating fan is connected and installed on the top of the box cover. The heat-conducting pipe is fixedly arranged at the bottom of the box body, and a plurality of groups of heat sinks are arranged inside the box body above the heat-conducting pipe.
[0020] The back-kitchen frying and fire prevention stove device also includes an air supply part, which includes an air collecting cover shell and a connecting pipe. The insertion rod is a tubular structure, and the top end of the insertion rod is rotatably connected to the air inlet hole on the side of the box body. The air collecting cover shell is located outside the pot body, the top end of the connecting pipe is connected to the bottom end of the insertion rod, and the bottom end of the connecting pipe is connected to the air collecting cover shell, and ventilation holes are provided on both sides of the frame shell.
[0021] When flames appear inside the pot body, the pot cover is closed on the pot body, and the heat pipe under the pot cover is immersed in the boiling oil inside the pot body. The temperature of the oil is conducted to the heat sink inside the box body along the heat pipe. When the electromagnet is powered off, the microcomputer operation screen synchronously controls the cooling fan to start, and the cooling fan quickly discharges the heat on the heat sink, that is, quickly cools down the oil inside the pot body. While the cooling fan discharges the air inside the box body, it also causes negative pressure inside the box body. The negative pressure inside the box body will cause the air on the side of the pot body to be replenished into the box body through the wind collecting cover, the connecting pipe and the plug rod. The wind collecting cover set on the side of the pot body will cause the air on the side wall of the pot body to circulate quickly, which has a certain heat dissipation effect on the pot body. That is, through the cooperation of the heat conduction and heat dissipation part and the air replenishment part, the heat conduction and the air circulation caused by the negative pressure generated by itself can be cleverly utilized to quickly cool down the oil inside the pot body, avoid the situation of the oil inside the pot body re-igniting after the pot cover is opened, and further improve the safety of the device when used.
[0022] The beneficial effects of the present application are as follows: the present application obtains a back-kitchen frying stove device through the above-mentioned design. By pulling the handle upward, the pot cover closed on the top of the pot body moves upward, and the electromagnet magnetically adsorbs and fixes the limit block, so that the pot cover is positioned after being flipped upward. When a flame appears on the pot body, the flame sensor can detect the flame on the pot body, and the electromagnet is powered off through the cooperation of the microcomputer operation screen. After the power is off, the electromagnet loses the magnetic attraction to the limit block, and resets the pot cover to close on the top of the pot body under the action of the gravity of the pot cover. At this time, the oil in the pot body is isolated from the external air, and the flame inside the pot body will automatically go out, which not only plays a good fire prevention role, but also plays a good protective role for the safety of the cooking personnel.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0030] A back-kitchen frying fire prevention stove device according to an embodiment of the present application is described below with reference to the accompanying drawings.
[0031] See also Figure 1-Figure 9 According to an embodiment of the present application, a back-kitchen frying and fire-proof stove device includes: a shell body part 10, a heating pot part 20 and a fire-proof covering part 30.
[0032] Among them, the heating pot part 20 and the fireproof covering part 30 are both installed above the shell body part 10. The heating pot part 20 is used for frying food, and the fireproof covering part 30 can extinguish the flame of the oil pan, ensuring the safety of the cooking personnel while avoiding property losses caused by the fire.
[0033] See also Figure 1-Figure 4The main body 10 of the housing includes a frame shell 110, a microcomputer operation screen 120 and a flame sensor 130. The microcomputer operation screen 120 is installed on the front side of the frame shell 110, the flame sensor 130 is arranged on the upper rear side of the frame shell 110, and through openings 140 are arranged on both sides of the upper side of the frame shell 110. The heating pot part 20 includes a pot body 210 and a heating assembly 220. The pot body 210 is installed inside the installation opening at the top of the frame shell 110, and the heating assembly 220 is arranged at the bottom of the pot body 210. The fireproof covering part 30 includes a pot cover 310, a support arm 330, a handle 340, a transmission shaft 350, a support 360, a plug rod 370, a limit block 380 and an electromagnet 390 with a hole-shaped structure in the middle. The two sets of supports 360 are respectively fixed on the top of the frame shell 110 located at the rear side of the pot body 210, the transmission shaft 350 rotates and penetrates the supports 360, the bottom end of the support arm 330 is fixedly arranged with the end of the transmission shaft 350, and the handle 340 is installed between the top ends of the two support arms 330. The pot cover 310 is located between the two support arms 330, and the shaft rod 320 is arranged on both sides of the pot cover 310. The shaft rod 320 and the support arm 330 are rotatably arranged. The bottom end of the plug rod 370 movably penetrates the through hole 140, and the top end of the plug rod 370 is rotatably arranged with the side of the pot cover 310. The limit block 380 is located inside the frame shell 110, and the limit block 380 is fixed to the bottom end of the plug rod 370. The electromagnet 390 is installed inside the frame shell 110 and below the through hole 140. The plug rod 370 movably penetrates the electromagnet 390, and the electromagnet 390 and the limit block 380 are magnetically adsorbed and matched.
[0034] The working principle of the back kitchen frying and fire prevention stove device is as follows: pull the handle 340 upward, and drive the pot cover 310 covered on the pot body 210 to move upward through the cooperation of the support arm 330 and the plug rod 370, until the limit block 380 at the bottom of the plug rod 370 contacts the electromagnet 390, and the electromagnet 390 magnetically absorbs and fixes the limit block 380, so that the pot cover 310 after turning upward is positioned. The heating component 220 heats the oil inside the pot body 210, and the food can be fried and cooked by putting it into the pot body 210. When the pot body 210 has a flame, the flame sensor 130 can detect the flame of the pot body 210, and the electromagnet 390 is powered off through the cooperation of the microcomputer operation screen 120. After the power is off, the electromagnet 390 loses the magnetic attraction to the limit block 380, and resets to cover the pot body 210 under the gravity of the pot cover 310. At this time, the oil in the pot body 210 is isolated from the external air, and the flame inside the pot body 210 will automatically go out, which not only plays a good fire prevention role, but also plays a good protective role for the safety of the cooking personnel.
[0035] After the electromagnet 390 in the above-mentioned back-kitchen frying anti-fire stove device is powered off, the pot cover 310 falls down and covers the pot body 210 by gravity. Due to the heavy weight of the pot cover 310 as a whole and the fast downward closing speed, the cooks may be easily injured while cooking, and the impact caused by the fast falling of the pot cover 310 may also easily cause damage to the device components.
[0036] See also Figure 5 and Figure 6 The back kitchen frying fire prevention stove device also includes a covering buffer part 40, which includes a pillar 410, a sleeve 420 with an arc structure, a sleeve rod 430 with an arc structure, a connecting column 440 and a piston 450. The bottom end of the pillar 410 is fixedly connected to the top of the frame shell 110 by bolts, and the sleeve 420 is fixed on the top of the pillar 410 by welding. The connecting column 440 connects the transmission shaft 350 and the sleeve rod 430, and the piston 450 is arranged at the bottom end of the sleeve rod 430, and the piston 450 is located inside the sleeve 420. The rotating transmission shaft 350 drives the piston 450 to move inside the sleeve 420 through the connecting column 440 and the sleeve rod 430, and the top of the sleeve 420 is provided with an exhaust hole 460.
[0037] When the electromagnet 390 is powered off and the pot cover 310 moves downward under the action of gravity, the rotating transmission shaft 350 will drive the sleeve rod 430 to rotate around the axial position of the transmission shaft 350 through the connecting column 440, and the rotating sleeve rod 430 will drive the piston 450 at the end to move inside the sleeve 420 to squeeze the air inside the sleeve 420, and the air inside the sleeve 420 will eventually be slowly discharged from the exhaust hole 460. In the process of the piston 450 squeezing the air inside the sleeve 420, the over-pressured air inside the sleeve 420 will slow down the rotation speed of the transmission shaft 350 through the sleeve rod 430 and the connecting column 440, that is, the pot cover 310 has a certain buffering effect when it falls and closes, and the pot cover 310 slowly closes on the pot body 210. After closing, the pot cover 310 will block the flame inside the pot body 210, playing a good fire prevention role. This design can effectively slow down the speed at which the pot cover 310 moves downward, and prevent the cook from being accidentally injured by the falling pot cover 310 when the pot cover 310 suddenly falls. In addition, the pot cover 310 is closed on the pot body 210 through the buffer cover, which can effectively reduce the impact between the pot cover 310 and the pot body 210, and also play a good protective role for the components in the device.
[0038] Among them, the arc-shaped structures of the sleeve rod 430 and the sleeve tube 420 both rotate around the axis of the transmission shaft 350, and the radius of the sleeve rod 430 and the sleeve tube 420 are the same, that is, when the transmission shaft 350 rotates, it can drive the piston 450 at the end of the sleeve rod 430 to move compressed air inside the sleeve tube 420.
[0039] Furthermore, the support 360 has a hollow structure inside, and the covering buffer part 40 is arranged inside the support 360. The support 360 is used to support the transmission shaft 350, and can also protect the components in the covering buffer part 40, so as to prevent the oil stains during cooking from contaminating the components in the covering buffer part 40, that is, to prevent the oil stains from entering the sleeve 420, and ensure that the piston 450 inside the sleeve 420 is in a flexible moving state for a long time, so as to play a good buffering role.
[0040] For specific settings, see Figure 3 The heating assembly 220 includes an electric heating tube 222, which is installed at the bottom of the pot body 210. The electric heating tube 222 heats the oil inside the pot body 210 at the bottom of the pot body 210. The heating assembly 220 also includes a shield shell 221, which is located outside the electric heating tube 222, and the shield shell 221 is fixed to the bottom of the pot body 210 by bolts, and the shield shell 221 protects the electric heating tube 222 at the bottom of the pot body 210. When the electromagnet 390 is powered off, the electric heating tube 222 in the heating assembly 220 is also powered off and stops heating the pot body 210.
[0041] In the above specific implementation, please refer to Figure 2 The frame 110 also includes a start switch 170, which is electrically connected to the microcomputer operation screen 120, and the microcomputer operation screen 120 is electrically connected to the flame sensor 130 and the electromagnet 390. The power supply outside the start switch 170 is connected to control the power switch of the entire device. The shell body 10 also includes a fuse 150, which is connected to the start switch 170 and the microcomputer operation screen 120, and the fuse 150 is used to protect the device components that use electricity. The shell body 10 also includes a working indicator light 160, which is connected to the power supply through the start switch 170. After the start switch 170 is turned on, the working indicator light 160 lights up, indicating that the device has been powered on. The heating pot part 20 also includes a temperature sensor 230, and the temperature sensor 230 and the electric heating tube 222 are electrically connected to the microcomputer operation screen 120 respectively. The temperature sensor 230 is used to detect the temperature inside the pot body 210 . A temperature regulating switch can be additionally provided on the front of the frame shell 110 , and the oil temperature inside the pot body 210 can be adjusted by the temperature regulating switch.
[0042] Furthermore, the handle 340 is rotatably connected to the support arm 330 , and a rubber sleeve is provided on the outside of the handle 340 . The provision of the rubber sleeve prevents the cook from slipping when holding the handle 340 and prevents the cook from being burned by the handle 340 .
[0043] Although the above-mentioned back-kitchen frying anti-fire stove device can extinguish the flame by covering the pot body 210 with the pot cover 310, the oil temperature inside the pot body 210 is too high. When the pot cover 310 is opened, the inside of the pot body 210 may re-ignite due to the excessively high oil temperature, which may easily cause injuries to the cook.
[0044] See also Figure 7-Figure 9 The back kitchen frying fire prevention stove device also includes a heat conduction and heat dissipation part 50, which includes a heat conduction pipe 510, a heat sink 520 and a heat dissipation fan 530. The pot cover 310 includes a box body 311 and a box cover 312, the shaft 320 is connected to the side of the box body 311, the side of the box body 311 is provided with an air inlet 313, the box cover 312 covers the top of the box body 311, and the heat dissipation fan 530 is connected and installed on the top of the box cover 312, the heat conduction pipe 510 is fixedly arranged at the bottom of the box body 311, and multiple groups of heat sinks 520 are arranged inside the box body 311 above the heat conduction pipe 510. The back kitchen frying fire prevention stove device also includes an air supply part 60, which includes an air collection cover 610 and a connecting pipe 620. The plug rod 370 is a tubular structure, and the top end of the plug rod 370 is rotatably connected to the air inlet 313 on the side of the box body 311, and the air collection cover 610 is located outside the pot body 210. The top end of the connecting pipe 620 is connected to the bottom end of the plug rod 370, and the bottom end of the connecting pipe 620 is connected to the air collection cover 610, and ventilation holes 180 are provided on both sides of the frame shell 110.
[0045] When flames appear inside the pot body 210, the pot cover 310 is closed on the pot body 210, and the heat pipe 510 below the pot cover 310 is immersed in the boiling oil inside the pot body 210. The temperature of the oil is transmitted to the heat sink 520 inside the box body 311 along the heat pipe 510. When the electromagnet 390 is powered off, the microcomputer operation screen 120 synchronously controls the cooling fan 530 to start, and the cooling fan 530 quickly discharges the heat on the heat sink 520, that is, quickly cools down the oil inside the pot body 210. The cooling fan 530 discharges the air inside the box body 311 to the outside and also causes negative pressure inside the box body 311. The negative pressure inside the box body 311 will cause the air on the side of the pot body 210 to be replenished into the box body 311 through the air collecting cover 610, the connecting pipe 620 and the plug rod 370. The air collecting cover 610 arranged on the side of the pot body 210 will cause the air on the side wall of the pot body 210 to circulate quickly, which has a certain heat dissipation effect on the pot body 210. That is, through the cooperation of the heat conduction and heat dissipation part 50 and the air replenishment part 60, the heat conduction and the air circulation caused by the negative pressure generated by itself can be cleverly utilized to quickly cool down the oil inside the pot body 210, so as to avoid the situation where the oil inside the pot body 210 re-ignites after the pot cover 310 is opened, and further improve the safety of the device when in use.
