Description

Technical Field

[0001] The present invention relates to the technical field of commercial gas stir-fry stoves, and specifically to an energy-saving commercial gas stir-fry stove. Background Technique

[0002] In order to improve the food delivery efficiency in the catering industry, various cooking utensils have been designed in the market currently. The commercial gas stir-fry stove is one of the many cooking utensils. Since the commercial gas stir-fry stove can use various gases such as liquefied petroleum gas, natural gas, and coal gas as fuel, the applicability of the commercial gas stir-fry stove is strong and it can meet different usage requirements;

[0003] In the prior art, the patent with the application number "CN202310844992.5" and the patent name "An energy-saving gas stir-fry stove" discloses that multiple groups of fan blades rotate on the shaft rod to generate a strong wind, so that the flue gas generated during work can enter the interior of the protective shell through the dust-proof net, then enter the first connecting pipe, and then converge in the third connecting pipe through the connecting valve, and finally pass through the heat absorption chamber. Multiple groups of heating red plates are arranged in the heat absorption chamber to absorb the waste heat in the flue gas, and then transfer it to the inner wall of the water storage chamber through the heat conduction plate, so as to heat the water source in the water storage chamber. The treated flue gas is then discharged through the air outlet pipe. A first filter screen and a second filter screen are movably installed in the inner wall of the air outlet pipe. The first filter screen and the second filter screen can prevent impurities such as particulate matter and grease from entering the internal parts of equipment such as the smoke exhaust pipe and the fan, which helps to reduce the dust accumulation and blockage of the equipment and reduce the load of the equipment;

[0004] In the prior art, the patent with the application number "CN202022825488.5" and the patent name "A gas high-energy-saving self-priming powerful fire stir-fry stove" discloses that a furnace bore is provided in the cyclone stove top. The bottom of the inner surface of the furnace bore is movably connected with a furnace core. A fuel inlet pipe is fixedly connected below the furnace core. An air inlet hole for fuel mixing and transmission is opened at the top of the furnace core. A self-priming air mechanism is arranged at the bottom end of the fuel inlet pipe. A heat accumulation stove is placed on the inner surface of the furnace bore. The inner surface of the heat accumulation stove is slidably connected with a burner cap. There is a combustion chamber on the burner cap. After the stove top gas is ignited and transmitted to the combustion chamber of the furnace core, gas enters from the main gas pipe, and when the gas is sprayed by the gas spray head, air is sucked into the fuel inlet pipe for mixing;

[0005] Although the commercial gas stir-fry stove mentioned above can suck air into the fuel inlet pipe for mixing when injecting gas through the gas nozzle during use, since both the gas nozzle and the fuel inlet pipe are fixedly installed, only simple mixing of air and fuel can be achieved, and the mixing effect cannot be improved by increasing the intersection angle of the airflows. As a result, the fuel and air are not sufficiently mixed, leading to poor combustion efficiency in the later stage and causing some unburned gas to be discharged. This not only wastes energy but also pollutes the environment when the commercial gas stir-fry stove is in use;

[0006] Therefore, we propose an energy-saving commercial gas stir-fry stove to solve the problems raised above. Summary of the Invention

[0037] Compared with the prior art, the beneficial effects of the present invention are as follows: This energy - saving commercial gas stir - fry stove can increase the included angle between the gas and air in the mixing pipe, thereby improving the mixing effect between the gas and air, enabling full mixing between the gas and air, improving the combustion efficiency, reducing pollutants generated by incomplete combustion, improving the thermal efficiency, avoiding energy waste, and saving energy when the commercial gas stir - fry stove is in use. The specific content is as follows:

[0038] (1) When the motor in the stir - fry stove table body drives the control rod to rotate reciprocally at a certain angle, the control rod can drive the mixing pipe to rotate reciprocally at a certain angle through the connecting rod. Therefore, through the rotational shaking of the mixing pipe, the included angle between the gas and air in the mixing pipe can be increased, thereby improving the mixing effect between the gas and air, enabling full mixing between the gas and air, improving the combustion efficiency, reducing pollutants generated by incomplete combustion, improving the thermal efficiency, avoiding energy waste, and saving energy when the commercial gas stir - fry stove is in use;

[0039] Since the first connecting hoses are connected to both the upper and lower ends of the mixing pipe, it is convenient for the connecting rod to drive the mixing pipe to revolve reciprocally at a certain angle around the center of the control rod;

[0040] Furthermore, when the control rod rotates reciprocally, it can pull the control rope reciprocally, and then the control rope can control the vertical rod to rotate reciprocally, so that the vertical rod drives the arc-shaped stirring component to rotate reciprocally. Thus, the stirring component rotates reciprocally around the center of the vertical rod, and then the two sets of stirring components arranged up and down can stir the water in the waste heat recovery tank, enabling the water in the waste heat recovery tank to effectively recover the heat generated on the surface of the furnace body during cooking. Therefore, this part of heat loss can be reduced, facilitating heat recovery. Later, the hot water in the waste heat recovery tank can be utilized, saving energy;

[0041] The main rotating rod drives the regulating plate to rotate, and then the second through hole in the regulating plate can coincide with the four first through holes in the upper and lower surfaces of the fixed frame in sequence. Then, the four upper discharge pipes are connected to the four lower discharge pipes through the second through hole in sequence. Therefore, it is convenient for the commercial gas stir-fry stove to use a variety of different fuels in sequence, avoiding the need to wait for replenishment after one kind of fuel in the commercial gas stir-fry stove is used up before it can be used again;

[0042] When the main rotating rod and the auxiliary rotating rod rotate, they can drive the cross bar and the arc-shaped rack assembly to rotate. Then, the rack assembly can be meshed with the corresponding transmission gears in sequence, causing the transmission gears to drive the "L"-shaped locking rod to rotate. Thus, the locking rod is separated from the card slot, facilitating the stretching out of the second connecting hose to be connected to an external gas storage tank;

[0043] Similarly, when not in use, the lower end of the locking rod can be manually rotated below the lower connecting disc, so that the locking rod hooks the lower part of the lower connecting disc, facilitating the placement of the retracted and unused second connecting hose and preventing the second connecting hose from being randomly draped; BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0056] Please refer to Figures 1-10 , the present invention provides the following technical solutions:

[0057] Embodiment 1: When the energy-saving commercial gas stir-fry furnace in this embodiment is in use, the fuel and air are not fully mixed, resulting in poor combustion efficiency in the later stage. This not only causes waste of energy but also pollutes the environment when the commercial gas stir-fry furnace is in use. To solve this problem, the following technical content is disclosed in this embodiment. The specific structure is as follows. Refer to Figures 1-7 and Figure 9As shown in the figure, it includes a cooking stove top body 1, and a partition plate 2 installed on the upper surface of the cooking stove top body 1. A filter plate 3 is installed in a groove on the front upper surface of the cooking stove top body 1. Sewage pipes 4 are installed through both the left and right side surfaces of the cooking stove top body 1. One end of the sewage pipe 4 is inserted into the groove below the filter plate 3. A control button mounting plate 5 and a wind valve 6 are installed on the front side surface of the cooking stove top body 1. The wind valve 6 is arranged below the control button mounting plate 5. Two furnace bodies 7 are symmetrically installed inside the upper surface of the cooking stove top body 1. A furnace core mechanism 11 is installed inside the furnace body 7, and a conveying pipe 152 is installed below the furnace core mechanism 11.

[0058] A mixing pipe 15 is installed inside the cooking stove top body 1. First connecting hoses 151 are installed at both the upper and lower ends of the mixing pipe 15. The upper first connecting hose 151 is connected to the conveying pipe 152, and the lower first connecting hose 151 is connected to a fixed pipe 153 installed on the upper surface of a fixed frame 17. The upper end of the upper discharge pipe 172 is connected to the fixed pipe 153. A control rod 16 is arranged on the right side of the mixing pipe 15. The upper part of the control rod 16 is connected to a motor inside the cooking stove top body 1. A connecting rod 161 is installed at the outer end of the control rod 16. The side surface of the connecting rod 161 is connected to the outer side surface of the mixing pipe 15. A water storage bucket 8 is installed at the middle position of the upper surface of the cooking stove top body 1. A water faucet 10 is installed above the rear side of the cooking stove top body 1. An air inlet pipe 13 is installed outside the fixed pipe 153. The outer end of the air inlet pipe 13 penetrates through the outer side surface of the cooking stove top body 1 and is connected to an external blower. The wind valve 6 controls the air volume inside the air inlet pipe 13.

[0059] The mixing pipe 15 forms a reciprocating rotation structure with the center of the control rod 16 as the center through the connecting rod 161. A waste heat recovery groove 12 in the shape of a circular ring is formed inside the cooking stove top body 1. The waste heat recovery groove 12 is arranged outside the furnace body 7. A water inlet pipe 101 for injecting water into the waste heat recovery groove 12 is installed on the upper surface of the cooking stove top body 1. A drain pipe 9 for discharging the water inside the waste heat recovery groove 12 is installed on the side of the cooking stove top body 1. Two stirring components 14 are symmetrically installed inside the waste heat recovery groove 12. The two stirring components 14 are arranged in a vertically staggered manner. Both of the two stirring components 14 are arranged in an arc shape structure. A vertical rod 141 is installed through one end of the stirring component 14. A scroll spring 142 is nested and connected to the outer side of the middle part of the vertical rod 141. A control rope 143 is wound and connected to the outer side of the lower end of the vertical rod 141. The stirring component 14 forms a reciprocating rotation structure with the center of the vertical rod 141 as the center. The outer end of the control rope 143 is connected to the control rod 16. The two control ropes 143 are arranged one above the other. The control rope 143 drives the vertical rod 141 to rotate through the rotation of the control rod 16.

[0060] First, move the entire commercial gas stir-fry stove into the working area, and then the entire commercial gas stir-fry stove can be used. At this time, the second through-hole 181 coincides with one group of the first through-holes 171, so that one of the upper discharge pipes 172 communicates with one of the lower discharge pipes 21 directly below. Then, stretch the second connecting hose 22 below one of the lower discharge pipes 21, and connect the second connecting hose 22 to the external gas storage tank. Then, start the control buttons for the ignition and main gas valve on the control button mounting plate 5. At this time, gas enters the fixed pipe 153 through the second connecting hose 22, the lower discharge pipe 21, and the upper discharge pipe 172. At the same time, start the blower connected to the outside of the air inlet pipe 13. The blower sends the external gas into the fixed pipe 153 through the air inlet pipe 13. At the same time, the flow rate of the air in the air inlet pipe 13 can be controlled by the air valve 6. Then, the gas and air in the fixed pipe 153 enter the mixing pipe 15 through the first connecting hose 151 after preliminary mixing;

[0061] Next, start the motor in the stir-fry stove top body 1 to drive the control rod 16 to perform a reciprocating rotation at a certain angle. At this time, the control rod 16 drives the connecting rod 161 to rotate together. Then, the connecting rod 161 drives the mixing pipe 15 to perform a reciprocating revolution at a certain angle with the center of the control rod 16 as the center. At this time, the first connecting hoses 151 at the upper and lower ends of the mixing pipe 15 are stretched. Therefore, by rotating the mixing pipe 15, the gas and air inside can be shaken, thereby increasing the included angle between the gas and air in the mixing pipe 15, greatly improving the mixing effect between the gas and air, enabling the gas and air to be fully mixed, thereby improving the combustion efficiency and avoiding the generation of a certain amount of pollutants due to incomplete combustion in the later stage, thus saving energy;

[0062] Then, the mixed gas and air in the mixing pipe 15 enter the furnace core mechanism 11 and the furnace chamber body 7 through the delivery pipe 152. At this time, ignition and combustion are carried out through the furnace core mechanism 11. Since this part is prior art, no detailed introduction will be made here. Then, the frying pan can be placed on the furnace chamber body 7 for frying operations;

[0063] During use, external water can be injected into the waste heat recovery tank 12 with an annular structure through the water inlet pipe 101. At this time, the water in the waste heat recovery tank 12 can recover the heat generated around the furnace body 7 and on the surface of the stir-fry furnace table body 1. At the same time, when the control rod 16 rotates reciprocally, it will reciprocally pull and wind the two control ropes 143, causing the control ropes 143 to reciprocally drive the vertical rod 141 to rotate. At this time, the scroll spring 142 stores energy. Then, the vertical rod 141 drives the arc-shaped stirring assembly 14 to rotate in the waste heat recovery tank 12. When the control rod 16 rotates in the reverse direction and does not pull and wind the two control ropes 143, at this time, the vertical rod 141 is automatically driven to rotate in the reverse direction by the energy stored in the scroll spring 142, causing the vertical rod 141 to drive the stirring assembly 14 to rotate in the reverse direction. Therefore, through the reciprocating rotation of the two sets of arc-shaped stirring assemblies 14 that are staggered up and down, it is convenient to stir the water in the waste heat recovery tank 12 well, so that the water at different positions in the waste heat recovery tank 12 is evenly heated, causing the water temperature in the waste heat recovery tank 12 to rise to recover the waste heat. Later, the water in the waste heat recovery tank 12 can be discharged through the drain pipe 9 for utilization, and then the waste heat can be recovered and utilized well, saving energy and facilitating the good use of the commercial gas stir-fry furnace.

[0064] Embodiment 2: The energy-saving commercial gas stir-fry furnace in this embodiment is based on Embodiment 1 and is convenient for sequentially replacing and using a variety of different fuels, with convenient operation. The specific structure is as follows. Refer to the attached Figure 3 and the attached Figures 5-9 As shown, two fixed frames 17 are symmetrically installed inside the bottom surface of the stir-fry furnace table body 1. Four first through holes 171 are equally spaced on the upper surface and the lower surface of the fixed frame 17. Upper discharge pipes 172 are sequentially installed in the four upper first through holes 171, and lower discharge pipes 21 are sequentially installed in the four lower first through holes 171. A regulating plate 18 is rotatably connected to the inside of the fixed frame 17 in a fitting manner. A second through hole 181 is opened inside the regulating plate 18. A main rotating rod 19 is installed on the bottom surface of the regulating plate 18. The lower part of the main rotating rod 19 penetrates through the bottom surface of the fixed frame 17. The bottom surface of the lower discharge pipe 21 is connected to the second connecting hose 22 through the upper connecting disc 211.

[0065] Since there are four sets each of the first through holes 171, the upper discharge pipes 172, the lower discharge pipes 21, and the second connecting hoses 22, the lower ends of the four second connecting hoses 22 can be respectively connected to storage tanks for four different internal fuels, and then the lower discharge pipes 21 and the upper discharge pipes 172 corresponding to and coinciding with the second through holes 181 are used to convey the fuels. When the fuels in the corresponding storage tanks are used up by the lower discharge pipes 21 and the upper discharge pipes 172 corresponding to and coinciding with the second through holes 181, the main rotating rod 19 can be manually rotated at this time. The main rotating rod 19 drives the regulation plate 18 to rotate, so that the second through hole 181 in the regulation plate 18 coincides with another set of first through holes 171, upper discharge pipes 172, and lower discharge pipes 21. Therefore, the other set of lower discharge pipes 21 and upper discharge pipes 172 corresponding to and coinciding with the second through hole 181 can be used to convey another fuel. Thus, it is convenient to replace and use another fuel. By operating in this way repeatedly, it is not necessary to use up one fuel and then only replenish one fuel before the commercial gas stir-fry stove can be used. Therefore, the use of the commercial gas stir-fry stove will not be delayed, and it is convenient to quickly replace the fuel, providing sufficient time for replenishing the fuel later.

[0066] Embodiment 3: The energy-saving commercial gas stir-fry stove in this embodiment, on the basis of Embodiment 2, facilitates the stretching use and retractable placement of the four second connecting hoses 22 in sequence. The specific structure is as follows. Refer to the attached Figures 8-10 As shown in the figure, a locking rod 212 with an "L" shape structure is installed below one side of the upper connection disk 211, and a transmission gear 213 is key-connected to the outer side above the locking rod 212; a lower connection disk 221 is installed on the outer side below the second connecting hose 22, and a card slot 222 with a "U" shape structure is opened inside one side of the lower connection disk 221. The lower connection disk 221 and the upper connection disk 211 are arranged in one-to-one correspondence; the lower part of the locking rod 212 is inserted into the card slot 222. Inside the bottom surface of the main rotating rod 19, a secondary rotating rod 20 is connected through a connecting spring 191. A through groove 204 is opened inside the upper part of the secondary rotating rod 20. A limiting post 192 is installed inside the lower part of the main rotating rod 19, and the limiting post 192 penetrates through the through groove 204. The height of the through groove 204 is greater than the diameter of the limiting post 192. The outer side of the secondary rotating rod 20 is connected to a rack assembly 203 through a cross bar 202. The rack assembly 203 is arranged in an arc shape structure, and the rack assembly 203 is meshed and connected with the transmission gear 213. An identification post 201 is installed on the outer side of the secondary rotating rod 20, and the identification post 201 and the first through hole 171 are on the same vertical plane.

[0067] When the entire commercial gas stir-fry stove is just produced and needs to be transported, the second connecting hose 22 can be manually pressed upward in sequence for contraction. At this time, the second connecting hose 22 drives the lower connecting plate 221 below to rise together, so that the lower end of the locking rod 212 is in the card slot 222. Then, the locking rod 212 is manually rotated so that the lower end of the locking rod 212 with an "L" - shaped structure rotates below the connecting plate 221. At this time, the "L" - shaped part at the lower end of the locking rod 212 is attached to the lower surface of the connecting plate 221. Then, the locking rod 212 can limit the connecting plate 221 to prevent the connecting plate 221 from descending, so that the second connecting hose 22 can be well - contracted, stored and placed, and prevent the second connecting hose 22 from hanging down randomly. Therefore, it is convenient for the later transportation and handling of the commercial gas stir - fry stove, and avoids the four groups of second connecting hoses 22 from hanging down and winding around each other;

[0068] When the commercial gas stir - fry stove is transported to the working area and the four groups of second connecting hoses 22 need to be stretched and then connected to the storage tanks with four different internal fuels, the secondary rotating rod 20 is manually rotated at this time. At this time, through the limiting column 192 inserted into the through - slot 204, the secondary rotating rod 20 drives the main rotating rod 19 to rotate together. When the secondary rotating rod 20 rotates, it drives the cross - bar 202 and the rack assembly 203 to rotate together. When the rack assembly 203 rotates, it is sequentially meshed with the four groups of transmission gears 213, so that the rack assembly 203 drives the transmission gears 213 to rotate in sequence. At this time, the transmission gears 213 drive the four groups of locking rods 212 to rotate, so that the lower end of the locking rod 212 rotates to directly below the card slot 222. At this time, the second connecting hose 22 can be manually pulled downward so that the upper connecting plate 211 is separated from the locking rod 212. The second connecting hose 22 is stretched to a certain length, and then the four groups of second connecting hoses 22 can be connected to the storage tanks with four different internal fuels;

[0069] When it is necessary to replace different fuels for use, first manually push the auxiliary rotating rod 20 upward. At this time, the auxiliary rotating rod 20 moves upward within the main rotating rod 19 to squeeze and store energy in the connecting spring 191. Then, the auxiliary rotating rod 20 drives the cross bar 202 and the rack assembly 203 to move upward together, so that the rack assembly 203 is disengaged from the transmission gear 213. At this time, rotate the auxiliary rotating rod 20 and the main rotating rod 19 by 90°. The main rotating rod 19 drives the regulation plate 18 to rotate within the fixed frame 17. Therefore, the second through hole 181 in the regulation plate 18 coincides with the four groups of first through holes 171, the upper discharge pipe 172, and the lower discharge pipe 21 in sequence. Thus, it is convenient to use different fuels, and the adjustment is convenient. At the same time, when the auxiliary rotating rod 20 rotates, it drives the identification column 201 to rotate. Since the identification column 201 and the second through hole 181 are on the same vertical plane, the position of the second through hole 181 can be known by observing the position of the identification column 201, which is convenient for the staff to see which fuel is being used, thereby completing a series of operations.
