Description

Technical Field

[0001] This invention relates to the field of burner technology, and in particular to an adjustable burner for a gas combination stove. Background Technology

[0002] Traditional household gas stoves have poor adjustability. The pot support is of a fixed size and cannot be adjusted to fit different sizes of cookware. This means that the gas stove can only use cookware of a fixed size and is not suitable for cookware of different sizes. If cookware of different sizes is used directly, the gas cannot heat the cookware evenly, and there are heating blind spots at the bottom of the cookware, resulting in temperature differences. This affects the heating effect of the burner and makes it less practical. Summary of the Invention

[0003] In order to overcome the shortcomings of existing gas stoves where the pot support size cannot be adjusted according to the specifications of the kitchen utensils used, making them unsuitable for different sizes of kitchen utensils and resulting in poor practicality, the purpose of this invention is to provide an adjustable burner for a gas combination stove with an adjustable pot support size.

A nozzle for spraying gas is installed at the end of the pipe. A guide rail that slides with the nozzle is fixedly connected to the top of the vent frame. A central opening is opened in the middle of the guide rail for the top of the burner body to pass through.

[0006] Preferably, the adjusting mechanism includes a worm gear, a fixed seat, and a worm. The worm gear is rotatably mounted on the vent frame, and the worm gear has evenly spaced spiral guide holes. The passage pipe slides in conjunction with the spiral guide holes. After the worm gear rotates, it can push the passage pipe outward through the spiral guide holes. Fixed seats are fixedly connected to both sides of the bottom of the stove cover. A worm is rotatably mounted on the fixed seat and meshes with the worm gear. The worm rotates through one side of the gas stove.

[0007] Preferably, a limiting mechanism is also included, which includes a rack, a second gear, and a clamping block. The side of the slide rod away from the second pot support is fixedly connected to a rack that slides and engages with the slide seat. The upper part of the slide seat is rotatably provided with a second gear that meshes with the rack. The side of the second gear away from the rack is fixedly connected to a clamping block that limits the position of the kitchen utensils above the second pot support.

[0008] Preferably, the gas stove also includes an air supply mechanism, which includes an air box, an air supply pipe, a connecting pipe, and an exhaust frame. The air boxes are symmetrically installed inside the gas stove to supply gas to the top of the burner body. The side of the air box closest to the burner body is connected to the air supply pipe, and the air supply pipe is connected to the guide rail. An exhaust frame located in the center opening is fixed between the middle of the guide rail and the burner body. An air outlet is opened on the exhaust frame to allow air to flow.

[0009] Preferably, the device also includes a rotating mechanism, which includes a guide ring, a rotating ring, and a gear ring.

Detailed Implementation

[0036] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] Example 1: An adjustable burner for a gas combination stove, as shown in the attached image. Figures 1-10The system includes a gas stove 1, a stove cover 2, a burner body 3, mounting rails 4, a pot support 41, a slide 42, a slide rod 43, a second pot support 44, an elastic element 45, a screw 46, a gear 47, an expansion mechanism 5, and an adjustment mechanism 6. Dust filters are fixed to the front and rear sides of the bottom of the gas stove 1. The burner body 3 is installed on both the left and right sides inside the gas stove 1, and gas passages are opened on both the left and right sides inside the burner body 3. The stove cover 2 has symmetrically arranged combustion ports corresponding to the burner body 3. Mounting rails 4 are symmetrically fixed to the left and right sides of the stove cover 2, located above the burner body 3. A first pot support 41 and a slide 42 are slidably mounted on the mounting rails 4 on both sides of the stove cover 2 at even intervals along the circumference. The first pot support 41 is used to support small kitchen utensils, and a second pot support 44 is rotatably mounted on the slide 42 to support large kitchen utensils. The first pot support 41 and the second pot support 44 are used to support small and large kitchen utensils respectively. The tops of both the first pot support 41 and the second pot support 44 are serrated to increase the friction between the first pot support 41 and the kitchen utensils, so that the kitchen utensils are placed stably. The sliding base 42 is provided with a sliding rod 43 whose top contacts the second pot support 44. An elastic element 45 is fixed between the sliding rod 43 and the sliding base 42 for elastically returning the sliding rod 43 upward after being pressed down. The elastic element 45 is a return spring. The end of the first pot support 41 and the sliding base 42 away from the combustion port is fixed with a screw 46 that is movable and cooperates with the stove cover 2. The screw 46 is threaded with a gear 47 that rotates and cooperates with the stove cover 2. The gear 47 is used to drive the screw 46 to move and adjust the position of the first pot support 41 and the second pot support 44. The burner body 3 is provided with an expansion mechanism 5 to expand the gas combustion diameter. An adjustment mechanism 6 is provided between the expansion mechanism 5 and the gas stove 1.

[0038] As attached Figure 1 , Figure 3 , Figure 4 , Figure 6 As shown in the figure, the extension mechanism 5 includes a ventilation frame 51, a support plate 52, a guide rail 53, a pipe 54, and a nozzle 55. A ventilation frame 51 is fixedly connected to the burner body 3 and communicates with one of the gas passages inside the burner body 3. A support plate 52 is fixedly connected to the upper part of the ventilation frame 51. A pipe 54 for conveying gas is slidably provided on the support plate 52 at even intervals along the circumference and communicates with the ventilation frame 51. The pipe 54 is a high-temperature resistant flexible hose. A nozzle 55 for spraying gas is installed at the top of the pipe 54. The nozzle 55 surrounds the top of the burner body 3. A guide rail 53 that slides with the nozzle 55 is fixedly connected to the top of the ventilation frame 51. A central opening is opened in the middle of the guide rail 53 for the top of the burner body 3 to pass through.

[0039] As attached Figure 1 , Figure 8 , Figure 9 and Figure 10The adjustment mechanism 6 includes a worm gear 61, a fixed seat 62, and a worm 63. The worm gear 61 is rotatably mounted on the ventilation frame 51 and located below the support plate 52. The worm gear 61 has evenly spaced spiral guide holes. The passage pipe 54 is slidably engaged with the spiral guide holes. After the worm gear 61 rotates, it can push the passage pipe 54 outward through the spiral guide holes. Fixed seats 62 are fixedly connected to both sides of the bottom of the stove cover 2. The worm 63, which meshes with the worm gear 61, is rotatably mounted on the fixed seat 62. The worm 63 rotates through the front side of the gas stove 1.

[0040] In use, adjust the size of pot support 1 (41) and pot support 2 (44) according to the specifications of the cookware. When adjustment is needed, rotate gear 1 (47) forward and backward. When gear 1 (47) rotates forward, the screw 46 under pot support 1 (41) moves pot support 1 (41) away from the burner. Simultaneously, the screw 46 under pot support 2 (44) also moves pot support 2 (44) away from the burner via the slide block 42. This moves pot support 1 (41) and pot support 2 (44) outward, expanding the placement space on them and increasing their size. When gear 1 (47) rotates backward, the screw 46 under pot support 1 (41) moves pot support 1 (41) closer to the burner. The screw 46 under pot support 2 (44) also moves pot support 1 (41) closer to the burner via the slide block 42. The sliding seat 42 moves the second pot support 44 closer to the combustion port, thereby moving the first pot support 41 and the second pot support 44 inward, reducing the placement space on the first pot support 41 and the second pot support 44, thus reducing their size. By rotating the gear 1 47 in both directions, the positions of the first pot support 41 and the second pot support 44 are adjusted to a suitable position to support the cookware, thus achieving the effect of adjusting the first pot support 41 and the second pot support 44, allowing the invention to be used with cookware of different sizes. Since the size of the first pot support 41 and the second pot support 44 has changed, in order to ensure uniform heating of the bottom of the cookware during subsequent gas combustion, the position of the nozzle 55 needs to be adjusted. This is done by rotating the worm gear 63, which drives the worm wheel 61. Rotating the worm gear 61 pushes the tube 54 outward through the spiral guide hole, causing the tube 54 to move the nozzle 55 on it outward together. When it is necessary to move the nozzle 55 inward, reverse the worm gear 63, causing the worm gear 61 to reverse and push the tube 54 inward through the spiral guide hole, causing the tube 54 to move the nozzle 55 on it inward together. By rotating the worm gear 63 in both directions, the nozzle 55 can be moved outward or inward to a suitable position, allowing the nozzle 55 to spray gas around the bottom of the cookware, expanding the diameter of the burned gas and covering the bottom of the cookware, so that the bottom of the cookware is heated evenly and the heating effect is guaranteed. When using this invention to heat objects inside the cookware, according to the size of the cookware, larger cookware is placed on the second pot support 44, and smaller cookware is placed on the first pot support 41. When the cookware is placed on the second pot support 44, the second pot support 44 will be pressed down, pushing the sliding rod 43 downwards and compressing the elastic element 45. Then, the burner body 3 is ignited by the gas stove 1, allowing gas to enter the burner body 3. The burner body 3 is ignited by its igniter, causing the gas to burn in the combustion port. Simultaneously, one of the gas passages within the burner body 3 will deliver some gas through the vent frame 51 and the pipe 54 to the nozzle 55. Finally, the nozzle 55 sprays out gas, which ignites the gas sprayed from the nozzle 55, evenly heating the bottom and surrounding area of ​​the cookware. When not in use, the burner body 3 is turned off by the gas stove 1, the cookware is removed, the elastic element 45 returns to its original position, and the second pot support 44 is pushed back up by the sliding rod 43.Thus, the present invention can be used through the above operations.

[0041] Example 2: Based on Example 1, as shown in the attached... Figure 1 , Figure 3 and Figure 4 It also includes a limiting mechanism 7, which includes a rack 71, a second gear 72 and a clamping block 73. The side of the slide rod 43 away from the second pot support 44 is fixedly connected to the rack 71, which slides and engages with the slide seat 42. The upper part of the slide seat 42 is rotatably provided with a second gear 72 that meshes with the rack 71. The side of the second gear 72 away from the rack 71 is fixedly connected to a clamping block 73 that limits the kitchen utensils above the second pot support 44.

[0042] When the cookware is placed on the second pot support 44, and the sliding rod 43 is pressed down, the sliding rod 43 drives the rack 71 to move downward. The rack 71 drives the clamping block 73 to rotate upward through the second gear 72. The upward rotating clamping block 73 will hold the cookware in place, thus limiting the size of the cookware on the second pot support 44 and ensuring the stability of the cookware, preventing it from falling off the second pot support 44. When the cookware is removed from the second pot support 44, the elastic element 45 resets, causing the sliding rod 43 to move upward and reset. The sliding rod 43 drives the clamping block 73 to reverse and reset through the second gear 72.

[0043] As attached Figure 1 , Figure 11 , Figure 12 and Figure 13 It also includes an air supply mechanism 8, which includes an air box 81, an air supply pipe 82, a connecting pipe 83, and an exhaust frame 84. The air box 81, consisting of a box and a fan, is symmetrically installed on the left and right sides of the rear side inside the gas stove 1. It is used to supply gas to the combustion port above the burner body 3. The air box 81 is connected to the front side of the air supply pipe 82. The air supply pipe 82 and the guide rail 53 are connected by a connecting pipe 83 at even intervals along the circumference. An exhaust frame 84 located in the center of the guide rail 53 is fixed between the middle of the guide rail 53 and the burner body 3. An air outlet is opened on the exhaust frame 84 for air circulation.

[0044] When in use, start the bellows 81. The fan inside the bellows 81 delivers air to the air outlet frame 84 through the air supply pipe 82 and connecting pipe 83. The air finally moves upward through the air outlet of the air outlet frame 84 to the combustion port, thereby providing sufficient air to the burner body 3 to prevent insufficient air during gas combustion and to ensure that the gas can burn normally, playing an auxiliary role. When no air supply is needed, turn off the bellows 81.

[0045] As attached Figure 1 , Figure 14 , Figure 15 , Figure 16 and Figure 17It also includes a rotating mechanism 9, which includes a guide ring 91, a rotating ring 92 and a gear ring 93. The guide ring 91 is fixedly connected to both the left and right sides of the top of the stove cover 2. The rotating ring 92 is rotatably mounted on the guide ring 91. The front end of the worm 63 and the rotating ring 92 are provided with protrusions to increase the friction between the hand and the worm 63 and the rotating ring 92, so as to facilitate the rotation of the worm 63 and the rotating ring 92. The gear ring 93 that meshes with the gear 47 is fixedly connected inside the rotating ring 92.

[0046] When it is necessary to adjust the size of the pot support 41 and the second pot support 44, rotate the rotating ring 92. The rotating ring 92 drives the gear ring 93 to rotate, and the gear ring 93 drives the gear 47 to rotate, so that all the pot supports 41 and the second pot support 44 on the mounting track 4 move outward at the same time. When it is necessary to move the pot supports 41 and the second pot support 44 inward at the same time, reverse the rotating ring 92. The rotating ring 92 drives the gear ring 93 to rotate in the opposite direction, and the gear ring 93 drives the gear 47 to rotate in the opposite direction, so that all the pot supports 41 and the second pot support 44 on the mounting track 4 move inward at the same time. In this way, the operation process of the present invention is optimized and convenient to use, without the need for manual adjustment of the position of the pot supports 41 and the second pot support 44 by rotating the gear 47 one by one.

[0047] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
