Description

Technical Field

[0001] The invention relates to the technical field of gas stoves, in particular to an air-gas linkage type large pot stove. Background Art

[0002] Gas stoves are very common cooking appliances. In the field of commercial stoves, large pot stoves have attracted much attention due to their sufficient firepower.

[0003] The patent with announcement number CN217235677U discloses a high-efficiency and energy-saving wind-air linkage large pot stove, which includes a furnace body, a furnace pit and a fire viewing port. A support shaft is rotatably connected to the furnace body, and the support shaft is arranged horizontally. The support shaft is located below the fire viewing port. The side wall of the support shaft is fixedly connected to a support plate. A fire-resistant reflector is fixed on the side of the support plate close to the furnace body. The mirror surface of the reflector can be aligned with the fire viewing port. A driving mechanism that can drive the support plate to flip is arranged on the furnace body. This solution provides a support plate that can swing up and down, and a reflector that can be aligned with the fire viewing port is arranged on the support plate. The user can open the support plate at any time and observe the flame in the furnace pit through the reflector. The user does not need to bend over to observe the flame, which improves the convenience of using the large pot stove.

[0004] However, in the process of increasing the gas supply and increasing the firepower, the above-mentioned large stove cannot automatically adjust the air supply according to the size of the gas supply. Gas combustion requires air and gas to be mixed in an appropriate proportion. If the gas supply increases but the air volume is not adjusted accordingly, insufficient air supply will lead to incomplete combustion of the gas. Unburned gas will be discharged into the air to form waste gas and harmful substances, such as carbon monoxide, nitrogen oxides, etc., which not only affect the kitchen environment, but also increase fuel loss and waste energy.

[0010] As a further solution of the present invention, the air outlet of the second air pipe is connected to the pot tank.

[0011] As a preferred embodiment of the present invention, the air outlet control mechanism includes two groups of connecting plates, which are connected and installed at one end of the air intake port of the fan.

[0015] Compared with the prior art, the beneficial effects of the wind-gas linkage large pot stove of the present invention are:

[0016] 1. After placing the pot in the pot groove and using the stove to ignite it, you can activate the ignition needle by twisting the flow knob to ignite the gas. After the gas is ignited, you can adjust the gas delivery flow by twisting the flow knob. In the process of twisting the flow knob, the ring groove opened at one end of the connecting ring will be twisted together. The ring groove is semi-annular from shallow to deep and is flush with the laser distance sensor, so that the flow knob can drive the ring grooves of different depths to be flush with the laser distance sensor. After the laser distance sensor detects the depth change of the ring groove, the laser distance sensor can send a signal to the controller, so that the controller can control the air outlet control mechanism to expand the corresponding caliber to allow the air supply mechanism to inhale air through the expanded caliber, so that the air supply mechanism can blow the inhaled air into the pot groove. The laser ranging sensor detects that the deeper the depth of the annular groove is, the larger the diameter of the expansion of the air outlet regulating mechanism will be, so that the air supply mechanism can inhale more air through a larger diameter. As the depth of the annular groove changes, the laser ranging sensor can accurately detect and reflect the changes in gas flow, and then adjust the air supply by controlling the air outlet regulating mechanism. Specifically, the deeper the annular groove is, the controller will automatically expand the air supply diameter and increase the air flow to ensure the best ratio of gas and air. This precise adjustment method can ensure that the firepower remains stable in different adjustment stages, avoid unstable firepower or flameout due to uneven air supply, and maintain the best ratio of gas and air to improve combustion efficiency and reduce energy waste.

[0017] 2. When supplying air to the pot groove to allow the gas to burn fully, the fan can be started to suck outside air into the first air pipe through the air outlet control mechanism connected to one end of the air intake port, and the air can be transported into the two groups of second air pipes through the first air pipe, and then the second air pipes can transport the air into the pot groove to mix with the burning gas, thereby ensuring the best ratio of gas and air, allowing the gas to burn completely, avoiding incomplete combustion caused by insufficient air, thereby improving combustion efficiency, reducing energy waste, making the cooking process more efficient, shortening cooking time, and reducing gas consumption.

[0018] 3. In the process of twisting the flow knob to increase the gas delivery volume, the annular groove opened at one end of the connecting ring will be twisted together. The annular groove is semi-annular from shallow to deep and is flush with the laser distance sensor, so that the flow knob can drive the annular grooves of different depths to be flush with the laser distance sensor. After the laser distance sensor detects the depth change of the annular groove, it can make the laser distance sensor send a signal to the controller, which can control the electric push rod to push the swivel to rotate the corresponding stroke in the connecting column. In the process of the swivel being pushed and rotated, it will drive the inclined slide groove opened at one end to push multiple groups of baffles pulled by the traction rod to slide synchronously to the outer end, so that the baffle can expand the diameter of the connecting plate, and provide a larger air intake for the fan to inhale air. This linkage adjustment ensures that the air intake diameter can be automatically increased according to demand while increasing the gas flow, so as to maintain the optimal ratio of gas and air, which helps to improve combustion efficiency, avoid incomplete combustion of gas, and reduce energy waste.

[0033] A connecting ring 106 is fixedly installed on the outer surface of the flow knob 103. A ring groove 102 is opened at one end of the connecting ring 106. The ring groove 102 is semi-annular from shallow to deep. The ring groove 102 is flush with the laser ranging sensor 105. The laser ranging sensor 105 is fixedly installed in the large stove body 1. The signal transmitting end of the laser ranging sensor 105 is connected to the signal receiving end of the controller. The control output end of the controller is electrically connected to the electrical control end of the air outlet control mechanism 3.

[0034] In the process of rotating the flow knob 103 to increase the firepower, the flow knob 103 can drive the annular groove 102 at one end of the connecting ring 106 to rotate, so that the annular grooves 102 of different depths can be flush with the laser ranging sensor 105, and the laser ranging sensor 105 can detect the depth change of the annular groove 102. The laser ranging sensor 105 can send a signal to the controller, and the controller can control the air outlet regulating mechanism 3 to expand the corresponding caliber to allow the air supply mechanism 2 to blow air into the pot groove. The deeper the depth of the annular groove 102 detected by the laser ranging sensor 105, the larger the caliber of the air outlet regulating mechanism 3 to be expanded by the controller.

[0035] The models of the laser distance sensor 105 and the controller are VL53L0X and Arduino Uno respectively.

[0036] Through the design of the flow knob 103, the annular groove 102, the laser distance sensor 105, the air supply mechanism 2 and the air outlet control mechanism 3, after the pot is placed in the pot groove and the stove 101 is used to ignite, the flow knob 103 can be twisted to activate the ignition needle to ignite the gas, and after the gas is ignited, the gas delivery flow rate can be adjusted by twisting the flow knob 103, and in the process of twisting the flow knob 103, the annular groove 102 opened at one end of the connecting ring 106 will be driven to twist together, and the annular groove 102 is semi-annular from shallow to deep and is flush with the laser distance sensor 105, so that the flow knob 103 can drive the annular grooves 102 of different depths to be flush with the laser distance sensor 105, and after the laser distance sensor 105 detects the depth change of the annular groove 102, the laser distance sensor 105 can send a signal to the controller, and the controller can control the air outlet control mechanism 3 to expand the corresponding caliber to allow the air supply mechanism 2 Air is sucked in through the expanded aperture, so that the air supply mechanism 2 can blow the inhaled air into the pot groove to match it with the delivered gas. The deeper the depth of the annular groove 102 detected by the laser ranging sensor 105, the larger the aperture of the air outlet regulating mechanism 3 will be controlled by the controller to allow the air supply mechanism 2 to inhale more air through a larger aperture. As the depth of the annular groove 102 changes, the laser ranging sensor 105 can accurately detect and reflect the changes in the gas flow rate, and then adjust the air supply by controlling the air outlet regulating mechanism 3. Specifically, the deeper the annular groove 102, the controller will automatically expand the air supply aperture and increase the air flow rate to ensure the optimal ratio of gas and air. This precise adjustment method can ensure that the firepower remains stable in different adjustment stages, avoid unstable firepower or flameout due to uneven air supply, and maintain the optimal ratio of gas and air to improve combustion efficiency and reduce energy waste.

[0037] like Figure 5 As shown, the air supply mechanism 2 includes two groups of fans 201, and the two groups of fans 201 are fixedly installed at both ends of the connecting rod 107 respectively. One end of the air intake port of the fan 201 is connected to an air outlet control mechanism 3, one end of the air outlet of the fan 201 is connected to a first air pipe 202, and one end of the first air pipe 202 is connected to two groups of second air pipes 203.

[0038] The air port of the second air pipe 203 is connected to the pot tank.

[0039] Through the design of the fan 201, the first air pipe 202 and the second air pipe 203, when air is supplied to the pot groove to allow the gas to burn fully, the fan 201 can be started to suck the outside air into the first air pipe 202 through the air outlet control mechanism 3 connected to one end of the air intake port, and the air is transported into the two groups of second air pipes 203 through the first air pipe 202, so that the second air pipe 203 can transport the air into the pot groove to mix with the burning gas, thereby ensuring the best ratio of gas and air, allowing the gas to burn completely, avoiding incomplete combustion caused by insufficient air, thereby improving combustion efficiency, reducing energy waste, making the cooking process more efficient, shortening cooking time, and reducing gas consumption.

[0040] like Figure 6-Figure 8 As shown, the air outlet control mechanism 3 includes two groups of connecting plates 302, and the two groups of connecting plates 302 are connected and installed at one end of the air intake port of the fan 201. A plurality of connecting columns 307 are fixedly installed between the outer peripheries of the two groups of connecting plates 302. Two groups of rotating rings 303 are rotatably installed in the connecting columns 307 of the two groups of connecting plates 302. A plurality of inclined grooves 304 are provided at one end of the two groups of rotating rings 303, and a plurality of guide columns 308 are slidably installed in the plurality of inclined grooves 304. Shielding plates 305 are fixedly installed on the outer surfaces of the plurality of guide columns 308, so that the plurality of shielding plates 305 can slide between the two groups of rotating rings 303.

[0041] The outer surfaces of the multiple groups of connecting columns 307 are all rotatably mounted with traction rods 309 , and the other end of each group of traction rods 309 is rotatably mounted on one end of the outer surface of each group of shielding plates 305 .

[0042] Push plates 306 are fixedly installed on the outer surfaces of the two sets of rotating rings 303. The two sets of pushing plates 306 extend from the connecting disk 302, and the piston rod of the electric push rod 301 is rotatably installed between the two sets of pushing plates 306. The other end of the electric push rod 301 is rotatably installed at one end inside the large stove body 1, and the electric push rod 301 is controlled by the controller, so that the two sets of rotating rings 303 can be pushed and rotated by the electric push rod 301, and then the rotating rings 303 can push multiple sets of baffles 305 pulled by the traction rod 309 to slide synchronously toward the outer end through the inclined slide groove 304, and the pushing distance of the electric push rod 301 changes with the depth of the annular groove 102 detected by the laser ranging sensor 105, so that the deeper the depth of the annular groove 102 is detected, the longer the pushing distance of the electric push rod 301 can be.

[0043] A guide rail groove 310 is formed at one end of each set of shielding plates 305 , and a guide rail block 311 is fixedly mounted at the other end of the shielding plates 305 . The shielding plates 305 slide in the guide rail groove 310 of another set of shielding plates 305 through the guide rail block 311 .

[0044] Through the design of the electric push rod 301, the connecting plate 302, the rotating ring 303, the inclined slide groove 304, the baffle plate 305, the pushing plate 306, the guide column 308 and the traction rod 309, when the flow knob 103 is twisted to increase the gas delivery amount, the annular groove 102 opened at one end of the connecting ring 106 will be twisted together. The annular groove 102 is semi-annular from shallow to deep and is flush with the laser distance sensor 105, so that the flow knob 103 can drive the annular grooves 102 of different depths to be flush with the laser distance sensor 105. After the laser distance sensor 105 detects the depth change of the annular groove 102, it can send a signal to the controller. The controller can control the electric push rod 301 to push the swivel 303 to rotate a corresponding stroke in the connecting column 307. During the process of the swivel 303 being pushed and rotated, the inclined slide groove 304 opened at one end will be driven to push multiple groups of baffles 305 pulled by the traction rod 309 to slide synchronously to the outer end, so that the baffle 305 can expand the diameter of the connecting plate 302, thereby providing a larger air intake for the fan 201 to absorb air. This linkage adjustment ensures that the air intake diameter can be automatically increased according to demand while increasing the gas flow rate, thereby maintaining the optimal ratio of gas to air, which helps to improve combustion efficiency, avoid incomplete combustion of gas, and reduce energy waste.

[0045] When the embodiment of the present invention is used according to the above technical solution, after the pot is placed in the pot groove and the stove 101 is used to ignite, the ignition needle can be activated by twisting the flow knob 103 to ignite the gas. After the gas is ignited, the gas delivery flow rate can be adjusted by twisting the flow knob 103. In the process of twisting the flow knob 103, the annular groove 102 opened at one end of the connecting ring 106 will be driven to twist. The annular groove 102 is semi-annular from shallow to deep and is flush with the laser ranging sensor 105, so that the flow knob 103 can drive the annular grooves 102 of different depths to be flush with the laser ranging sensor 105. After the laser ranging sensor 105 detects the depth change of the annular groove 102, it can send a signal to the controller, so that the controller can control the electric push rod 301 to push the rotating ring 303 to rotate the corresponding stroke in the connecting column 307. , and the process of the rotating ring 303 being pushed and rotated will drive the inclined slide groove 304 opened at one end to push multiple groups of baffles 305 pulled by the traction rod 309 to slide and expand synchronously to the outer end, so that the baffle 305 can expand the diameter of the connecting plate 302, thereby providing a larger air suction port for the fan 201 to absorb air, and then the fan 201 can be started to suck the outside air into the first air pipe 202 through the connecting plate 302 connected to one end of the air suction port, and the air is transported into the two groups of second air pipes 203 through the first air pipe 202, so that the second air pipe 203 can transport the air into the pot groove to mix with the burning gas, thereby ensuring the optimal ratio of gas and air, allowing the gas to be completely burned, and this linkage adjustment ensures that the air suction diameter can be automatically increased according to demand while increasing the gas flow, thereby maintaining the optimal ratio of gas and air.

[0046] In summary, the embodiment of the present invention can automatically expand the air intake diameter according to the gas delivery volume, so that the fan 201 can inhale more air flow through the expanded diameter. The linkage adjustment ensures that the air intake diameter can be automatically increased according to demand while increasing the gas flow, thereby maintaining the optimal ratio of gas and air, so as to improve combustion efficiency, avoid incomplete combustion of gas, and reduce energy waste.
