Description

Technical Field

[0001] The invention belongs to the technical field of gas stoves, and in particular relates to a Chinese cooking stove with an improved wind and gas linkage module structure. Background Art

[0002] The Chinese cooking stove is a high-power stove specially designed for hotels, guesthouses, canteens, fast food restaurants and other places for quickly frying Chinese dishes. It has the characteristics of fast heating speed, controllable temperature, strong firepower and strong enough power. The traditional Chinese cooking stove generally includes a stove body, an air intake module and an air intake module. The air intake module includes a small fire gas path and a small fire gas valve controlling the small fire gas path, a main gas path and a main air valve controlling the main gas path. The air intake module includes a fan, an air intake path and an air intake valve controlling the air intake path. When in use, first open the small fire gas valve and light a small fire (long-lasting fire), then open the main gas valve, and at the same time adjust the air intake valve and light the main fire.

[0003] A Chinese utility model patent with publication number "CN2429763Y" discloses an air-wind linkage device for a gas-fired blast stove, including a gas pipe and an air duct. The gas pipe is provided with a gas valve. The rear end of a rotating shaft on the gas valve is connected with a connecting rod, and the other end of the connecting rod is fixed to an air valve flap arranged in the air duct. The connecting rod of this scheme is directly connected to the gas valve and the air valve flap. When the gas valve is rotated, the air valve flap can also be driven to rotate, so that the gas valve and the air valve flap are linked.

[0004] The air-wind linkage device of the above-mentioned gas-fired blast stove provides a solution for simultaneously opening and closing the gas valve and the air valve flap through a connecting rod. However, there are gaps between the connecting parts of the connecting rod structure, making it difficult to achieve precise transmission. This also leads to errors when adjusting the wind and air, and the structure is relatively complex and the cost is relatively high.

[0005] The Chinese utility model patent with the publication number "CN214949221U" discloses an air-air linkage regulating air valve, including a main air valve and an air duct with elbows at both ends, and an regulating air blade and a flow-limiting air blade are arranged in the air duct. The regulating air blade is connected to a rotating shaft, one end of which passes through the air duct and is provided with an air valve gear, the main air valve is connected to an air valve gear, and the air valve gear and the air valve gear are engaged with each other, and the gear transmission is more accurate and efficient.

[0006] The through hole for adjusting the air intake on the ball valve inside the common gas valve on the market is circular. This results in a sharp change in the connecting area of ​​the ball valve in the gas pipe even if the ball valve is rotated slowly and at a uniform speed, which in turn causes a sharp change in the growth rate of the air intake, making it impossible to accurately control the air intake. Similarly, the above two solutions both adjust the air intake through the air valve flap (adjusting the air blade), and the air valve flap (adjusting the air blade) cannot accurately control the air intake when adjusting the air intake.

[0007] In the above two existing technical solutions, since the ventilation volume of the ball valve and the ventilation volume of the air duct increase nonlinearly relative to the rotation of the ball valve, it is difficult for the gas stove to maintain a stable air-air ratio when the combustion changes, and it is difficult to ensure the stability of the combustion of the gas stove. That is, if the increase in the air intake at the gas valve exceeds the increase in the air intake of the air valve flap, the gas will not be fully burned due to insufficient oxygen; on the contrary, if the increase in the air intake is greater than the increase in the air intake, the combustion effect will be affected by excessive air volume; and if the air-air ratio is to be kept consistent, the design difficulty and process requirements of the two will be greatly increased, and the manufacturing cost will be greatly increased. Summary of the invention

[0008] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a Chinese cooking stove which can accurately control the air intake, has a more stable air ratio, and has a simple structure and low cost.

[0009] The purpose of the present invention can be achieved by the following technical solutions:

[0010] A Chinese cooking stove with an improved air-wind linkage module structure comprises a stove stand, a stove head, a mixing chamber, a fan and an air-wind linkage module, wherein the air-wind linkage module comprises a mounting plate, an air duct and an air duct fixedly connected to the mounting plate, a small fire valve, a solenoid valve, a main air valve, a main air valve and a linkage mechanism, wherein the main air valve comprises a main air shaft, a main air handle and an opening and closing member respectively fixedly connected to both ends of the main air shaft, wherein the opening and closing member is provided with a front-to-back through-channel, wherein both ends of the channel are gas inlets and outlets, and at least one gas inlet and outlet is in the shape of a long strip; the main air valve comprises a gate installation opening opened on the upper surface of the air duct, a rectangular gate inside the air duct, and a gate, wherein the gate vertically cuts into the gate opening from the gate installation opening; the linkage mechanism is respectively connected to the main air valve and the main air valve, and the main air valve drives the gate to slide up and down in the gate opening through the linkage mechanism to control the opening and closing of the air duct and adjust the air intake.

[0011] In this scheme, the small fire valve, the main gas valve, and the solenoid valve are respectively connected to the airway and can control the small fire air intake, the main fire air intake and the total air intake respectively. When the main gas valve is rotated, the connecting area between the long strip gas inlet and outlet and the air intake pipe increases slowly, and its growth trend is linear relative to the rotation angle of the gas valve, that is, the growth trend of the air intake is linear and slowly increases, and the air intake can be adjusted more accurately, which is more controllable than the prior art. When the gas stove is turned off, the gate piece in the gate completely closes the gate. With the rotation of the main gas valve, the gate piece in the gate of the main air valve is driven to rise through the linkage mechanism, and the rectangular gate is gradually opened from completely closed. The ventilation area of ​​the gate increases steadily and slowly, and the air intake relative to the rotation angle of the gas valve is also linear. The growth trend of the air intake is linear and slowly increases, and the air intake can also be controlled more accurately. Since the growth trend of air intake is linear and slow when the main air valve and the main air valve are adjusted, it is easier to synchronize the growth of air intake and air intake through simple design and debugging. The main air valve and the main air valve are connected through a linkage mechanism to form a linkage whole. The main air valve, the main air valve and the linkage mechanism cooperate with each other. When in use, only by adjusting the rotation angle of the main air valve, the air-air ratio can be kept in a stable ratio state to maintain the best combustion effect. This patent can keep the air-air ratio stable and precisely controlled through simple structural design improvements. Compared with the prior art, it is less difficult to design, simpler in structure and lower in production cost.

[0012] In the air-wind linkage module for the gas Chinese cooking stove, the linkage mechanism includes a driven shaft rotatably connected to the mounting plate, a main air gear fixedly mounted on the main air shaft, and a driven gear fixedly connected to the driven shaft. The driven gear is meshed with the main air gear. A rotating part is also fixedly connected to the driven shaft. The linkage mechanism also includes a pull rod, which is vertically arranged. The upper end of the pull rod is rotatably connected to the rotating part, and the lower end of the pull rod is fixedly connected to the gate plate.

[0013] When the main air valve is rotated, the main air gear drives the driven gear to rotate, thereby driving the driven rotating shaft and the rotating part on the driven rotating shaft to rotate, and the connecting part on the rotating part rotates circumferentially along the connection point between the rotating part and the driven rotating shaft, driving the pull rod and the gate plate at the bottom of the pull rod to rise and fall. The transmission has high accuracy and efficiency, simple and compact structure, high transmission efficiency, and precise linkage control of the main air valve and the main air valve can be completed only through a simple mechanical structure, and the production cost is also lower.

[0014] Furthermore, a connecting piece is fixedly arranged on the rotating piece, and the outer end of the connecting piece is rotatably connected with the pull rod. The structure is simple, the rotation efficiency is high, and the production and processing are convenient.

[0015] Furthermore, the rotating member is circular, and the connection point between the driven shaft and the rotating member is located at the center of the rotating member. The structure is simple and modular, and is easy to produce and assemble.

[0016] Furthermore, the driven shaft passes through the mounting plate, and the rotating member, the connecting member, the pull rod, the main air valve and the air duct are all located on the back of the mounting plate. The air duct, the small fire valve, the solenoid valve and the main air valve are arranged on the front of the mounting plate facing the user for easy operation, and the rotating member, the connecting member, the pull rod, the main air valve and the air duct that do not need to be operated during use are arranged on the back of the mounting plate, saving space on the front and also preventing the user from accidentally touching the above components during operation.

[0017] In the air-gas linkage module for the gas Chinese cooking stove, air inlets and air outlets are arranged at both ends of the air duct.

[0018] Furthermore, a main air valve is provided at one end of the air inlet, and a low-fire air outlet is provided on the air duct. The low-fire air outlet and the low-fire valve are connected to the stove through a three-way pipe.

[0019] The main air valve is used to debug the total air intake during the production stage, so as to further improve the stability of the ratio of air intake and gas volume. After debugging, no secondary adjustment is required by the user, which is convenient for user operation. The small fire air outlet is connected to the small fire valve and the stove head through the delivery pipe and the three-way joint respectively, providing a stable air volume for the small fire.

[0020] Furthermore, the two ends of the air duct are connected to the fan and the mixing chamber through air ducts respectively, and the main air valve is connected to the mixing chamber through the main air pipe.

[0021] The stove, mixing chamber and fan are all installed on the stove frame. The modular air-gas linkage module is more convenient to assemble and disassemble with the stove. The air and gas are premixed in the mixing chamber and then sent to the stove, which further improves the combustion efficiency and also improves the stability of the stove fire.

[0022] Furthermore, the channel is in the shape of a through long strip, which has a simple structure, is easy to process, reduces processing costs, and is conducive to modular production.

[0023] Compared with the prior art, the technical effects of the present invention are:

[0024] First, in the Chinese cooking stove with improved wind-air linkage module structure, the strip channel of the opening and closing parts is a long rectangular strip, and the gate is also a rectangle. When adjusting the air intake and air intake, the growth trends of the two are linear, and the air intake and air intake can be adjusted more accurately.

[0025] Secondly, the Chinese cooking stove with improved wind and gas linkage module structure achieves the coordinated cooperation of the main gas valve, the main air valve and the linkage mechanism, and adjusts the growth rates of the air intake and the air intake to be similar. When in use, only the main gas valve needs to be adjusted to ensure that the ratio of wind and gas is always in the optimal stable state, thereby maintaining the best combustion effect.

[0026] Third, the Chinese cooking stove improved by the air-wind linkage module structure has a simple overall structure, high transmission accuracy and efficiency, and can complete precise linkage control of the main air valve and the main air valve only through a simple mechanical structure. It can also be produced in a modular manner, with lower production costs, and is more convenient to assemble and disassemble with the stove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1 , Figure 8 As shown, a Chinese cooking stove with an improved air-wind linkage module structure comprises a stove frame 9, a stove head 91, a mixing chamber 92, a fan 93 and an air-wind linkage module 95. The stove head 91, the mixing chamber 92, the fan 93 and the air-wind linkage module are all installed on the stove frame 9. The modular air-wind linkage module 95 is more convenient to assemble and disassemble with the stove frame 9. The air and gas are premixed in the mixing chamber 92 and then fed into the stove head 91, which further improves the combustion efficiency and also improves the stability of the stove head fire.

[0040] like Figure 2 , Figure 3 As shown, the air and gas linkage module 94 includes a mounting plate 1, an air duct 2 and an air duct 3 fixedly connected to the mounting plate 1, a low-fire valve 4, a solenoid valve 5, a main air valve 6, a main air valve 7 and a linkage mechanism 8. The low-fire valve 4, the main air valve 6 and the solenoid valve 5 are respectively connected to the air duct 3 and can respectively control the low-fire air intake, the main fire air intake and the total air intake.

[0041] Preferably, Figure 4 As shown, the main air valve 6 includes a main air shaft 61, a main air handle 62 and an opening and closing member 63 respectively fixedly connected to both ends of the main air shaft 61. The opening and closing member 63 is provided with a long rectangular strip channel 631 which runs through the front and back. When the air intake increases, the connecting area between the strip channel 631 and the pipeline gradually increases, and its growth trend is linear, so that the growth trend of the air intake is also linear, which can more accurately control the air intake and the increase range of the air intake.

[0042] Preferably, Figure 5 As shown, the main air valve 7 includes a gate installation opening 71 opened on the upper surface of the air duct 2, a rectangular gate 72 inside the air duct 2, and a gate 73. The gate 73 is laterally cut into the gate 72 from the gate installation opening 71. When the gas stove is turned off, the gate 72 is completely closed by the gate 73 in the gate 72. With the rotation of the main air valve 6, the gate 73 in the gate 72 of the main air valve 7 is driven to rise through the linkage mechanism 8, and the gate 72 is gradually opened from being completely closed. Because the gate 72 is also rectangular, the growth trend of the ventilation area of ​​the gate 72 is also linear, so the growth trend of the air intake is also linear, and the air intake and the growth trend of the air intake can also be more accurately controlled.

[0043] Furthermore, one end of the linkage mechanism 8 is connected to the main air valve 6 and the other end is connected to the gate plate 73. When in use, the main air valve 6 is rotated, and the gate plate 71 is driven by the linkage mechanism 8 to slide up and down in the gate 72 to control the opening and closing of the air duct 2 and adjust the air intake. The main air valve 6 and the main air valve 7 form a linked whole through the linkage mechanism 8. While opening and closing the main air valve 6, the opening and closing of the main air valve 7 and the air intake can also be adjusted. Because the growth trends of the air intake and the air intake are linear when the main air valve 6 and the main air valve 7 are gradually opened, the growth range of the air intake and the air intake can be adjusted to be the same through debugging. Through the coordinated cooperation of the main air valve 6, the main air valve 7 and the linkage mechanism 8, when in use, only the main air valve 6 is adjusted to ensure that the wind and gas ratio is always in the optimal stable state, thereby maintaining the best combustion effect.

[0044] Preferably, Figure 7 As shown, the linkage mechanism 8 includes a driven shaft 81 rotatably connected to the mounting plate 1, a main air gear 82 fixedly mounted on the main air shaft 61, and a driven gear 83 fixedly connected to the outer end of the driven shaft 81. The driven gear 83 is meshed with the main air gear 82. A circular rotating member 84 is also fixedly connected to the driven shaft 83. The connection point between the driven shaft 81 and the rotating member 84 is located at the center of the rotating member 84. A connecting member 85 is provided on the rotating member 84. A pull rod 86 is connected to the outer end of the connecting member 85. The pull rod 86 is vertically arranged and the lower end of the pull rod 86 is fixedly connected to the gate plate 73. When the main air valve 6 is rotated, the main air gear 82 drives the driven gear 83 to rotate, thereby driving the driven rotating shaft 81 and the rotating member 84 on the driven rotating shaft 81 to rotate, and the connecting member 85 on the rotating member 84 rotates circumferentially along the connection point between the rotating member 84 and the driven rotating shaft 81, driving the pull rod 86 and the gate plate 73 at the bottom end of the pull rod 86 to rise and fall. The transmission has high accuracy and efficiency, and the precise linkage control of the main air valve 6 and the main air valve 7 can be completed only through a simple mechanical structure, and the production cost is also lower.

[0045] Preferably, Figure 2 , Figure 3 As shown, the driven shaft 81 passes through the mounting plate 1, and the rotating member 84, the connecting member 85, the pull rod 86, the main air valve 6 and the air duct 2 are all located on the back of the mounting plate 1. The air duct 3, the small fire valve 4, the solenoid valve 5 and the main air valve 6 are arranged on the front of the mounting plate facing the user for easy operation, and the rotating member 84, the connecting member 85, the pull rod 86, the main air valve 6 and the air duct 2 are arranged on the back of the mounting plate 1, which saves space on the front and also prevents the user from accidentally touching the above components during operation.

[0046] Preferably, Figure 6As shown, an air inlet 21 and an air outlet 22 are provided at both ends of the air duct 2 and are connected to the fan and the stove body through the ventilation pipe 9 respectively. A main air valve 23 is also provided at one end of the air inlet 21, and a small fire air outlet 24 is also provided on the air duct 2. The main air valve 23 is used to debug the total air intake volume during the production stage, thereby further improving the stability of the ratio of the air intake volume and the air intake volume. After the debugging is completed, the user does not need to make a secondary adjustment, which is convenient for the user to operate and use. The small fire air outlet 24 is connected to the small fire valve 4 and the stove head 91 respectively through the delivery pipe and the three-way pipe 41 to provide a stable air volume for the small fire.

[0047] Preferably, Fig. 9 , Fig.10 As shown, the channel 631 is in the shape of a through long strip as a whole, which is easy to process, reduces processing costs, and is conducive to modular production.

[0048] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope defined by the claims of the present invention.
