Description

Technical Field

[0001] The utility model relates to the technical field of gas cookers, in particular to a gas cooker. Background Art

[0002] The burner of a gas stove usually includes two air inlets, each of which is provided with a damper plate. Rotating the damper plate can change the air inlet area of ​​the burner and the external environment. Existing gas stoves adjust the gas flow rate by rotating the valve stem of the valve body connected to the burner to achieve different dimensions and calorific value areas. For different dimensions and calorific value areas, it is necessary to manually adjust the damper plate to adjust the air inlet area between the air inlet and the external environment. Otherwise, the flame will be separated and the fire will not be ignited due to the large air inlet area; or the combustion will be insufficient due to the small air inlet area, and the smoke will be too much, which will affect the combustion performance of the gas stove. However, users usually do not know how to adjust, and professional maintenance personnel are required to come to the door to adjust, which brings great inconvenience to users and increases after-sales costs.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In the description of the present application, it should be understood that the terms "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0040] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0041] like Figure 1 and Figure 2 As shown, this embodiment provides a gas cooker, including a panel assembly 7, a bottom shell assembly 8, a burner 4 and a valve body 1, the burner 4 and the valve body 1 are both arranged in the bottom shell assembly 8, and the panel assembly 7 is covered on the bottom shell assembly 8. A nozzle 6 is arranged at one end of the valve body 1, and the nozzle 6 is connected to the burner 4 through a spring 5, and gas is provided to the burner 4 through the valve body 1. A valve stem 11 that can rotate relative to the valve body 1 and control the opening size of the valve body 1 is arranged in the valve body 1, and the amount of gas entering the burner 4 is adjusted or changed by rotating the valve stem 11. The burner 4 includes at least two air inlets, and each air inlet is correspondingly provided with a damper plate 2, and the damper plate 2 can rotate relative to the air inlet to change the air inlet area of ​​the air inlet. The damper plate 2 is provided with an adjustment hole, and the damper plate 2 rotates relative to the air inlet to change the connection area between the adjustment hole and the air inlet, which can change the air inlet area between the air inlet and the external environment, thereby changing the air inlet area of ​​the burner 4, that is, changing the air inlet amount of the burner 4.

[0042] The combustion of a gas stove requires the provision of gas and oxygen. The gas and oxygen are mixed and burned to produce a flame. The combustion performance of the gas stove is related to the amount of gas supplied to the burner 4 by the valve body 1 and the amount of air entering the burner 4 through the air inlet. The amount of gas and the amount of air need to be supplied to the burner 4 at a set ratio to ensure that the gas is fully burned. If the air intake is too large, the flame generated by the combustion of the burner 4 will be separated or unable to ignite. If the air intake is too small, the gas will not burn fully and more smoke will be generated. The valve stem 11 of the gas stove is connected to the knob 71. The user drives the valve stem 11 to rotate by rotating the knob 71, and then adjusts the amount of gas to achieve adjustment of different dimensions and calorific value areas.

[0043] In order to ensure the combustion performance of the gas cooker in different dimensions and calorific value areas, the gas cooker provided in this embodiment also includes a damper adjustment mechanism 3, such as Figure 2 and Figure 3As shown, the damper adjustment mechanism 3 includes a transmission member and at least two groups of adjustment components, each group of adjustment components is connected to a damper plate 2, and the adjustment component is used to adjust the air inlet area of ​​the damper plate 2 relative to the air inlet. The valve stem 11 is simultaneously connected to at least two groups of adjustment components through the transmission member, and the air inlet area of ​​the air inlet increases with the increase of the opening of the valve body 1. By setting a damper adjustment mechanism 3, the valve stem 11 is connected to the damper plate 2 through the damper adjustment mechanism 3, so that the damper plate 2 can rotate with the rotation of the valve stem 11, and the valve stem 11 is connected to at least two groups of adjustment components through a transmission member, and each group of adjustment components is correspondingly connected to a damper plate 2. The rotation of the valve stem 11 can simultaneously adjust the air inlet area of ​​at least two air inlets, and the air inlet area of ​​the air inlet increases with the increase of the opening of the valve body 1, so that the air inlet area of ​​the burner head 4 increases or decreases with the increase or decrease of the gas amount, thereby ensuring the combustion performance of the gas stove in different dimensions and calorific value areas, avoiding flame separation and failure to ignite due to excessive air inlet area, or insufficient combustion and excessive smoke due to too small air inlet area, making it more convenient for users to use, and eliminating the need for professional maintenance personnel to make on-site adjustments, thereby reducing after-sales costs.

[0044] In one embodiment, the transmission member includes a driving gear 31, and the adjustment assembly includes a driven gear 32 and a transmission shaft 33. The driving gear 31 is provided on the valve stem 11, and the driven gear 32 is meshed with the driving gear 31 for transmission. The two ends of the transmission shaft 33 are respectively connected to the driven gear 32 and the damper plate 2 to drive the damper plate 2 to rotate. Exemplarily, the burner head 4 includes two air inlets, two damper plates 2 are provided, and two adjustment assemblies are also provided. The driving gear 31 is sleeved on the valve stem 11, and the two driven gears 32 are arranged at intervals in the circumference of the driving gear 31, and the two driven gears 32 are meshed with the driving gear 31 for transmission, so as to rotate the valve stem 11 through the knob 71. The rotation of the valve stem 11 drives the driving gear 31 to rotate, and the driving gear 31 drives the two driven gears 32 to rotate at the same time, so that the two damper plates 2 can be driven to rotate respectively through the two transmission shafts 33, so that the valve stem 11 rotates to adjust the amount of gas supplied to the burner 4, and the two damper plates 2 can adjust the air inlet areas of the two air inlets as the valve stem 11 rotates, so that the air inlet areas of the two air inlets increase with the increase of the gas amount and decrease with the decrease of the gas amount, so that the air inlet areas of the two air inlets can be automatically adjusted in different dimensions and calorific value areas, avoiding the flame separation and failure to ignite due to too large an air inlet area; or the problems of insufficient combustion and excessive smoke due to too small an air inlet area, thereby improving the combustion performance.

[0045] The driving gear 31 and the driven gear 32 can be cylindrical gear meshing transmission, or helical gear or bevel gear meshing transmission. The helical gear or bevel gear meshing transmission can change the direction of the output shaft, so that the transmission shaft 33 can be directly connected to the damper plate 2 to drive the damper plate 2 to rotate.

[0046] Specifically, Figure 4 As shown, a first limiting surface 311 is provided in the center hole of the driving gear 31, and a second limiting surface 111 is provided on the outer periphery of the valve stem 11, which cooperates with the first limiting surface 311 and limits the rotation of the driving gear 31 relative to the valve stem 11. The first limiting surface 311 and the second limiting surface 111 cooperate to achieve the fixing of the driving gear 31 and the valve stem 11, so that the driving gear 31 can rotate with the rotation of the valve stem 11, thereby ensuring that the meshing transmission of the driving gear 31 and the driven gear 32 can transmit the rotational force of the valve stem 11, and further ensuring that the damper plate 2 can rotate with the rotation of the valve stem 11. Of course, in other embodiments, the center hole of the driving gear 31 can also be interference-fitted with the valve stem 11.

[0047] In one embodiment, the adjustment assembly further includes an adjustment gear 34, which is connected to one end of the transmission shaft 33 away from the driven gear 32, and a toothed adjustment portion 21 is provided on the circumference of the adjustment damper plate 2, and the adjustment gear 34 is meshed with the toothed adjustment portion 21. The driven gear 32 drives the transmission shaft 33 to rotate, the transmission shaft 33 drives the adjustment gear 34 to rotate, and the adjustment gear 34 drives the damper plate 2 to rotate, so as to adjust the air intake area of ​​the air inlet.

[0048] In one embodiment, the transmission ratio of the transmission member to the adjustment component is 1:1.9 to 1:2. In this embodiment, the valve stem 11 rotates 180° and the damper plate 2 can rotate 360°. When the valve stem 11 rotates to the point where the gas amount supplied by the valve body 1 to the burner 4 is the maximum, the damper plate 2 rotates to the air inlet to obtain the optimal air inlet area corresponding to the maximum gas amount; when the valve stem 11 rotates to the point where the gas amount supplied by the valve body 1 to the burner 4 is the minimum, the damper plate 2 rotates to the air inlet to obtain the optimal air inlet area corresponding to the minimum gas amount.

[0049] In this embodiment, the maximum air inlet area of ​​the air inlet is 15 grids, the optimal air inlet area corresponding to the maximum gas volume is 12 grids, and the optimal air inlet area corresponding to the minimum gas volume is 3 grids.

[0050] In one embodiment, the diameter of the driving gear 31 is the same as the diameter of the driven gear 32, and the diameter of the driven gear 32 is 1.9 to 2 times the diameter of the adjusting gear 34. Of course, in other embodiments, the diameter of the driving gear 31 can also be set to be 1.9 to 2 times the diameter of the driven gear 32, and the diameter of the adjusting gear 34 can be the same as the diameter of the driven gear 32.

[0051] In one embodiment, the axial direction of the driven gear 32 and the axial direction of the adjusting gear 34 are both parallel to the axial direction of the driving gear 31, and the transmission shaft 33 is bendable to connect the driven gear 32 and the adjusting gear 34. Since the plane where the air inlet is located is parallel to the axial direction of the valve stem 11 and is arranged on a vertical plane, the adjusting gear 34 is meshed with the toothed adjusting portion 21 for transmission, the axial direction of the driven gear 32 and the axial direction of the adjusting gear 34 are both parallel to the axial direction of the valve stem 11, and the driven gear 32 and the adjusting gear 34 are arranged at intervals in the horizontal direction. In order to realize the transmission between the driven gear 32 and the adjusting gear 34, the transmission shaft 33 is arranged to be bendable to realize the transmission connection between the driven gear 32 and the adjusting gear 34.

[0052] In one embodiment, the transmission shaft 33 includes a first transmission shaft 331, a second transmission shaft 332 and a connecting shaft 333, wherein the first transmission shaft 331 is arranged at the center of the driven gear 32, the second transmission shaft 332 is arranged at the center of the adjusting gear 34, and the connecting shaft 333 is bendably connected to the first transmission shaft 331 and the second transmission shaft 332. The first transmission shaft 331 and the second transmission shaft 332 are respectively connected to the driven gear 32 and the adjusting gear 34 to ensure the stability of the meshing. The connecting shaft 333 can be made of a bendable material with lower hardness. The first transmission shaft 331 and the second transmission shaft 332 are connected by the connecting shaft 333, so as to realize the transmission of force between the driven gear 32 and the adjusting gear 34 whose axes are parallel and arranged at intervals in the horizontal direction. In this embodiment, the connecting shaft 333 is made of steel wire.

[0053] In one embodiment, the damper adjustment mechanism 3 further includes a first mounting plate 35, the first mounting plate 35 passes through the valve stem 11 and is connected to the end surface of the valve body 1, and the first transmission shaft 331 is rotatably arranged on the first mounting plate 35. The first mounting plate 35 is set as a horizontal plate, and a through hole, a connecting hole and a first matching hole are arranged on the horizontal plate. The through hole is arranged at the center of the horizontal plate, and two connecting holes are arranged symmetrically relative to the through hole. After the horizontal plate passes through the valve stem 11 through the through hole, two screws are respectively passed through the two connecting holes and are screwed to the valve body 1. There are also two first matching holes, and the two first transmission shafts 331 are connected to the first matching holes in a one-to-one correspondence.

[0054] Specifically, Figure 3 and Figure 5As shown, the first transmission shaft 331 is provided with a first positioning member 3311 and a first clamping groove 3312, the driven gear 32 is provided between the first positioning member 3311 and the first clamping groove 3312, and the first transmission shaft 331 is clearance-matched with the first matching hole, so that the first transmission shaft 331 can rotate relative to the first mounting plate 35. After the first transmission shaft 331 passes through the first matching hole, a first clamping member 3313 is provided in the first clamping groove 3312 to clamp with the first mounting plate 35, so that the first transmission shaft 331 is rotatably provided on the first mounting plate 35, the center hole of the driven gear 32 is interference-matched with the first transmission shaft 331, so that the driven gear 32 can drive the first transmission shaft 331 to rotate, and the first positioning member 3311 and the first mounting plate 35 limit the driven gear 32 to prevent the first transmission shaft 331 from moving up and down during the rotation process, thereby ensuring the stability of the engagement between the driven gear 32 and the driving gear 31, and further ensuring the stable transmission of the rotation force.

[0055] Of course, in other embodiments, first bearings may be provided in both first matching holes, and the two first transmission shafts 331 may respectively cooperate with the inner rings of the two first bearings to enable the first transmission shaft 331 to rotate relative to the horizontal plate, thereby causing the driving gear 31 to rotate, driving the driven gear 32 to rotate, and the driven gear 32 drives the first transmission shaft 331 to rotate. The first transmission shaft 331 transmits the rotational force to the second transmission shaft 332 through the connecting shaft 333, and the second transmission shaft 332 drives the adjusting gear 34 to rotate, and the adjusting gear 34 drives the damper plate 2 to rotate.

[0056] In one embodiment, if Figure 2 and Figure 3 As shown, the damper adjustment mechanism 3 also includes a second mounting plate 36, and the second mounting plate 36 includes a first connecting plate 361 and a second connecting plate 362 which are perpendicularly arranged to each other, the first connecting plate 361 is perpendicular to the first mounting plate 35, the damper plate 2 is rotatably arranged on the first connecting plate 361, and the second transmission shaft 332 is rotatably arranged on the second connecting plate 362.

The rotation of the damper plate 2 can change the connection area between the adjustment hole and the corresponding hole, thereby adjusting the air inlet area of ​​the air inlet. Two second matching holes are arranged on the second connecting plate 362 corresponding to the two damper plates 2, and the two second matching holes are connected to the two second transmission shafts 332 in a one-to-one correspondence.

[0057] Specifically, the second transmission shaft 332 is provided with a second positioning member 3321 and a second clamping groove 3322, the adjusting gear 34 is provided between the second positioning member 3321 and the second clamping groove 3322, the second transmission shaft 332 is clearance-matched with the second matching hole, and after the second transmission shaft 332 passes through the second matching hole, a second clamping member 3323 is provided in the second clamping groove 3322 to clamp with the second connecting plate 362. The second transmission shaft 332 is rotatably provided on the second connecting plate 362, and the center hole of the adjusting gear 34 is interference-fitted with the second transmission shaft 332, so that the rotational force transmitted from the driven gear 32 to the connecting shaft 333 through the first transmission shaft 331 can be transmitted to the adjusting gear 34 through the second transmission shaft 332, and then the adjusting gear 34 is matched with the toothed adjusting portion 21 to drive the damper plate 2 to rotate. Moreover, the second positioning member 3321 and the second connecting plate 362 limit the adjusting gear 34 to prevent the second transmission shaft 332 from moving up and down during rotation, thereby ensuring the stability of the engagement between the adjusting gear 34 and the toothed adjusting portion 21, and then enabling the damper plate 2 to rotate with the rotation of the valve stem 11, thereby achieving adjustment of the air inlet area of ​​the air inlet.

[0058] Of course, in other embodiments, a second bearing may also be disposed in the second matching hole, and the second transmission shaft 332 may be rotatably disposed on the second connecting plate 362 via the second bearing.
