Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas stove technology, specifically a gas stove. Background Technology
[0002] Existing gas stoves typically consist of a chassis, a main body, and an air damper adjustment device. The air damper adjustment device controls combustion efficiency by adjusting the air-to-gas mixture ratio. If the gas stove chassis does not have openings, adjusting the air damper requires disassembling the entire stove, which is cumbersome and inconvenient for technicians or service personnel. Furthermore, heat buildup inside the chassis can affect the lifespan of the valve body and burner. Some gas stoves have openings in the chassis below the air damper adjustment device, allowing direct operation and adjustment. However, these openings can easily lead to dust and grease clogging the gas nozzles, or insects entering and clogging the nozzles. Additionally, the openings may lack leak-proof design, allowing liquids to flow into the cabinets. For example, Chinese patent literature discloses a gas stove that facilitates air damper adjustment and battery replacement [Publication No.: CN203349330U]. By providing holes on the panel surface near the air damper adjustment plate, the air damper can be adjusted directly on the gas stove panel without lifting the entire stove. The battery compartment can also be installed near these holes, or in a convenient location for battery replacement. In practical use, this offers advantages such as easy air damper adjustment and battery replacement, and improved cooking comfort. However, with holes on the gas stove panel and the battery compartment also located near these holes, water and spills can easily enter the chassis through the holes, affecting battery life. Therefore, there is an urgent need for a gas stove that can protect the openings from foreign object intrusion, provide convenient air damper adjustment, and has a reliable structure.

[0041] The following is combined with Figures 1-13 The following describes some embodiments of the present invention in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0042] Example 1:
[0043] Reference Figure 1-6This embodiment discloses a gas stove, including a gas stove panel 1, a burner cap 11, and a valve body 12. The burner cap 11 is disposed above the gas stove panel 1 and is used to generate a flame. The burner cap 11 includes an outer ring burner cap 111 and an inner ring burner cap 112, with the outer ring burner cap 111 fitted radially outside the inner ring burner cap 112. The valve body 12 is used to control the gas entering the gas stove and can adjust the gas flow according to the user's needs to adjust the size of the flame at the burner cap 11. It also includes a chassis 2 and a main body 3, including a damper adjustment device 31, which is mounted on the chassis 2. The damper adjustment device 31 includes an operating part 311 and a damper 312. A through hole 21 is provided on the chassis 2, and the operating part 311 faces the through hole 21. The operating part 311 can be operated through the through hole 21 to adjust the size of the damper 312. A hole cover 4 is mounted on the through hole 21 and is provided with an adjustable operating hole 41. The operating part 311 can be operated through the operating hole 41 to adjust the damper 312.
[0044] Reference Figure 6 This embodiment provides a gas stove with an adjustable operating hole 41 provided through the hole cover 4. When the operating hole 41 is open, the technician can reach into the gas stove base 2 through the operating hole 41 and then directly operate the operating part 311 of the air damper adjustment device 31. Without disassembling the overall structure, the size of the air damper 312 can be quickly adjusted to control the mixing ratio of gas and air, which is very convenient. At the same time, it can improve the air flow in the base 2. Because the gas stove continuously generates high temperature, the temperature inside the base 2 is high, forming a low-pressure area inside. In contrast, the outside ambient temperature is normal air, maintaining standard atmospheric pressure, forming a high-pressure area outside. When a pressure difference is formed between the inside and outside, the operating hole 41 allows the cold air from the outside to flow from the high-pressure area to the low-pressure area inside the gas stove base shell. The resulting airflow circulation can reduce the temperature inside the gas stove base 2. At the same time, because the through hole 21 is close to the valve body 12 and the burner, the temperature rise of the burner and valve body 12 is most significant when the gas stove is working. Therefore, the through hole 21 can also reduce the temperature between the valve body 12 and the burner. When the operating hole 41 is closed, the base 2 is sealed, which can prevent insects or oil stains from entering the nozzle and clogging it. It can also isolate external pollutants, thereby extending the service life of the nozzle. It can also prevent overflow from pots or gas stove leaks from entering the gas stove base 2. It can also prevent the overflow or sewage from flowing into the cabinet through the through hole 21, which would cause the cabinet to corrode or become difficult to clean over time, resulting in a poor user experience.
[0045] In this embodiment, refer to Figure 7The hole cover 4 includes a fixing frame 42, which is mounted on the through hole 21. The fixing frame 42 has at least two opposing side frames, and a fixing structure 421 is provided on the side frames. The fixing frame 42 is mounted on the through hole 21 through the fixing structure 421. The hole cover 4 is mounted on the through hole 21 through the fixing frame 42. This arrangement makes the hole cover 4 and the fixing frame 42 not integrally formed, which facilitates installation and disassembly during the production process.
[0046] In this embodiment, the fixing structure 421 is a buckle 4211 set on the frame, and the through hole 21 is provided with a corresponding snap-fit position; or, the fixing structure 421 is a snap-fit position set on the frame, and the through hole 21 is provided with a corresponding buckle 4211; or, the fixing structure 421 is a mounting hole set on the frame and the through hole 21, and is fixedly connected with screws. The above-mentioned snap-fit or screw connection method, on the one hand, fixes the hole cover 4 and the through hole 21 through the fixing structure 421, so that they will not move or rotate during use or transportation, and can also prevent the hole cover 4 from falling off due to unstable installation, ensuring a tight connection between the hole cover 4 and the through hole 21, improving the reliability of the structure. On the other hand, the snap-fit or screw connection is low in cost, very convenient to install and disassemble, and can be adapted to different scenarios, improving installation flexibility.
[0047] In this example, refer to Figure 7 The cover 4 includes a movable plate 43, which comprises a first movable plate 431 and a second movable plate 432. The first movable plate 431 and the second movable plate 432 are movable relative to each other. By moving either movable plate, the technician can adjust the size of the operating hole 41, achieving dynamic adjustment of the size of the operating hole 41. The technician can operate the operating part 311 of the damper 312 without fully opening the operating hole 41, thereby adjusting the size of the damper 312, reducing the risk of foreign object intrusion, and allowing the operating hole 41 to be in an open or closed state according to actual needs, adapting to various operational requirements. If the size of the operating hole 41 is fixed, it cannot be adapted to different tools or hand sizes, resulting in inconvenience in operation.
[0048] In this example, refer to Figure 8The fixed frame 42 includes a long frame A and a short frame B. Two raised ribs 422 are formed on the inner edge of the long frame A, extending in a straight line. Slide grooves are provided on both the first and second movable plates, conforming to the raised ribs. One raised rib corresponds to the slide groove of the first movable plate, and the other corresponds to the slide groove of the second movable plate. Preferably, the cross-section of the raised rib 422 is semi-circular. By forming the raised rib 422 on the long frame of the fixed frame 42, the cooperation between the slide groove and the raised rib allows the first and second movable plates 431 and 432 to move linearly, ensuring smooth adjustment and precise positioning. This also prevents jamming or offset during sliding of the movable plates. The raised rib 422 has a simple structure and requires no additional sliding device. Furthermore, by setting the slide groove, frictional resistance can be reduced, extending the service life of the movable plates.
[0049] In this example, the first movable plate 431 and the second movable plate 432 are connected by a connecting device 44. The connecting device 44 is installed at the center of the intersection of the first movable plate 431 and the second movable plate 432. The connecting device 44 includes a latching groove 442 fixed on the first movable plate 431 and a latching head 441 fixed on the second movable plate 432; or, the connecting device 44 includes a latching head 441 fixed on the first movable plate 431 and a latching groove 442 fixed on the second movable plate 432. The first movable plate 431 and the second movable plate 432 are fixed by the connecting device 44. When it is necessary to adjust the size of the damper 312 or to reduce the temperature of the gas stove base 2, the connecting device 44 is opened and the movable plate 43 is moved so that the operating hole 41 is opened. When it is not necessary to adjust the size of the damper 312, the movable plate 43 can be fixed so that the operating hole 41 is in a closed state to prevent liquid from overflowing into the cabinet. Thus, the first movable plate 431 and the second movable plate 432 are positioned relative to each other when not in use, avoiding accidental opening of the operating hole 41 and causing liquid to overflow into the cabinet.
[0050] In this example, refer to Figure 13-14 The fixed frame 42 has guide grooves 423 at its four top corners. When the movable plate 43 is installed, it is difficult to align the movable plate 43 and the fixed frame 42 in a small space. By designing the guide grooves 423, the curved surface of the guide grooves 423 can guide the movable plate 43 to be quickly positioned in the fixed frame 42 during installation, improving the assembly efficiency and preventing the first movable plate 431 and the second movable plate 432 from rotating left and right.
[0051] In this embodiment, at least one protrusion 424 is provided on the bottom side edge of the fixing frame 42. The protrusion 424 forms a force point. When the technician is disassembling the hole cover 4 structure, fingers or operating tools can be inserted through the protrusion 424 to remove the hole cover 4 from the through hole 21.
[0052] In this embodiment, refer to Figure 4 The edge of the through hole 21 is provided with a flange 211, which is an upwardly curved arc structure. When liquid overflows from the burner into the gas stove base 2, the flange 211 can prevent the overflow from flowing into the cabinet through the through hole 21. The flange 211 also plays a certain role in guiding the overflow, allowing the overflow to flow quickly along the junction of the flange 211 and the base 2 to other flat areas of the base 2, making it convenient for users to clean up the overflow. The upwardly curved arc structure of the flange 211 is used to blunt the edge, making it less sharp. This can prevent assembly personnel from cutting their hands or tools during the assembly of other parts during production, and can also prevent users from cutting their hands or tools when cleaning the gas stove or adjusting the air damper 312, thus improving safety. In addition, the arc structure can enhance the structural strength of the flange 211. At the same time, the flange forms the aforementioned snap-fit position, allowing the hole cover to be installed on the through hole by a snap-fit.
[0053] In this embodiment, there are at least two through holes 21, and they are not arranged in parallel. There are two air damper adjustment devices 31 for the lower air intake burner. Therefore, at least two through holes 21 are provided. The non-parallel arrangement of the through holes 21 is to adapt to the position of the air damper adjustment device, making it easier for technicians to operate the two air damper adjustment devices 31 and support the independent adjustment of the two air dampers 312, thereby improving the combustion control accuracy. On the other hand, the space around the gas stove air damper adjustment device 31 is limited, and the non-parallel arrangement can increase the area of the through holes 21. The non-parallel layout of the through holes 21 allows airflow to enter the chassis 2 from different angles, which helps to reduce the temperature inside the chassis 2.
[0054] Example 2:
[0055] The only difference between this embodiment and Embodiment 1 is that the connecting device 44 includes a latching head 441 and a latching groove 442. Both the first movable plate 431 and the second movable plate 432 have short and long sides. The latching head 441 is installed at the center of the short edge of the first movable plate 431, and the second movable plate 432 has at least one latching groove 442 along the center line of its short side. This multi-position latching groove 442 design allows for precise adjustment of the size of the operating hole 41. The size of the operating hole 41 can be flexibly adjusted according to the user's gas stove usage environment. Once the required size is determined, the first movable plate 431 and the second movable plate 432 can be fixed in place. This allows for adjustment of the air damper 312 when the hole is large, and for heat dissipation of the gas stove chassis 2 when the hole is small, while also preventing liquid spillage into the cabinet to some extent. The latching groove 442, located along the center line of the short side of the second movable plate 432, ensures even force distribution and improves structural reliability.
[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
