Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a damper adjustment structure and an integrated stove. Background Technology

[0002] Gas combustion is affected by air mixing degree and air volume. Adjusting the primary air intake can improve these factors. The primary air intake utilizes the ejector principle, where high-speed fluid generates negative pressure to draw surrounding air into the burner. The primary air intake volume can be adjusted by regulating the air intake area at the burner. Primary air adjustment is a crucial factor in the completeness of gas combustion. Current integrated cooktops often employ a flexible shaft structure for primary air adjustment, incorporating a damper and gear mechanism at the burner head, with the flexible shaft connecting to the gears, and the adjustment position located below the cooktop panel. However, this flexible shaft structure requires high precision components, is prone to jamming, and can cause permanent damage to the flexible shaft if over-adjusted. Furthermore, the cost of this structure is very high.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation of the present invention and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present invention encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0033] like Figure 1 , Figure 2 As shown, this embodiment of the utility model provides a damper adjustment structure, including a damper plate 1, an adjusting rod 2, and a valve body 3. The damper plate 1 is rotatable around its own axis, and its edge is provided with adjusting teeth 11 distributed in an arc shape. One end of the adjusting rod 2 is provided with a gear 21 corresponding to the adjusting teeth 11, and the other end of the adjusting rod 2 is provided with an adjusting part 22. The valve body 3 is provided with a through mounting hole 31, and the adjusting part 22 is located in the mounting hole 31.

[0034] The damper adjustment structure provided in this embodiment of the utility model has an air inlet baffle at the inlet of the burner injector tube during installation. The air inlet baffle and the damper plate 1 have corresponding air inlet holes. When the damper plate 1 rotates, the overlapping area (air inlet area) of the air inlets between them changes, thereby achieving the purpose of primary air conditioning. When adjustment is needed, the adjusting part 22 of the adjusting rod 2 can be rotated using a tool, which in turn causes the gear 21 of the adjusting rod 2 to rotate. Since the gear 21 meshes with the adjusting gear 11, it can drive the damper plate 1 to rotate, achieving the purpose of adjustment. Compared with the existing flexible shaft structure, this embodiment of the utility model adopts a rigid shaft structure, which is simple and stable, not easily damaged, has low requirements for component precision, is not easily jammed, and has low overall cost. Furthermore, using a flexible shaft structure for adjustment requires the installation of a rotary adjuster, whose bracket can partially obstruct the air inlet holes of the damper plate, resulting in a reduced and uneven amount of injected air, insufficient mixing with the combustion gas, and combustion problems such as high flue gas concentration and low thermal efficiency. This embodiment of the invention employs a rigid shaft structure, eliminating the need for a rotary adjuster. Therefore, it does not obstruct the air intake or affect the amount of air injected. Finally, in this embodiment, the adjusting rod 2 passes through the valve body 3, allowing it to share an opening on the same panel, thus avoiding the need for additional openings on the cooktop (especially integrated cooktops) casing.

[0035] The valve body 3 is a device for controlling the amount of gas injected. It generally has a valve stem and a knob 32. The knob 32 is connected to the valve stem, and the valve stem can be rotated by the knob 32 to adjust the amount of gas injected. Figure 3 , Figure 4 As shown, in one embodiment of this utility model, a knob decorative plate 33 is provided on the outer side of the valve body 3, which covers the mounting hole 31 and the adjustment part 22. This prevents accidental contact with the adjustment part 22 and subsequent changes in combustion conditions when disassembling the knob 32. Furthermore, the knob 32 covers the knob decorative plate 33, making the overall appearance more aesthetically pleasing after assembly.

[0036] To limit the position of the adjusting rod 2, such as Figure 5 As shown, in one embodiment of this utility model, the adjusting rod 2 is provided with a cylindrical limiting protrusion 23, which is located inside the adjusting part 22. The valve body 3 has a limiting block 34 corresponding to the limiting protrusion 23 on its inner side. The limiting block 34 has a limiting groove 341 corresponding to the adjusting rod 3, and the limiting groove 341 has a clearance groove 342 corresponding to the limiting protrusion 23 in its center. The opening width of the limiting groove 341 is smaller than the diameter of the adjusting rod 2. The limiting protrusion 23 is located within the clearance groove 342, and the opening width of the limiting groove 341 is smaller than the diameter of the adjusting rod 2, which can limit the position of the adjusting rod 2 in the front-back, up-down, and left-right directions. Furthermore, the adjusting rod 2 or the limiting block 34 is made of a material with low hardness that can deform, such as plastic, to facilitate assembly.

[0037] like Figure 1 As shown, in order to facilitate the rotation of the adjusting rod 2, in one embodiment of this utility model, the adjusting part 22 is provided with a cross-shaped or straight groove, which can be easily adjusted with an existing screwdriver.

[0038] like Figure 1 , Figure 2 As shown, in one embodiment of this utility model, there are two damper plates 1, two adjusting rods 2, and two mounting holes 31, corresponding to the structure of two ejector tubes. Furthermore, in order to avoid the adjusting teeth 11 of the two damper plates 1 affecting each other, the two damper plates 1 have a height difference in the axial direction, so that the adjusting teeth of the two damper plates are staggered to avoid mutual collision.

[0039] like Figure 6 As shown, this utility model also provides an integrated stove, including the aforementioned damper adjustment structure. Further, the integrated stove also includes a housing 4 and a burner 5 disposed within the housing 4. The burner 5 generally includes a main body 51 and an injector tube 52. The burner 51 is connected to the injector tube 52. An air inlet baffle 53 is provided at the inlet of the injector tube. The damper plate 1 is mounted on a nozzle 54 and is spring-loaded against the air inlet baffle 53 of the injector tube 52, but can rotate axially. The nozzle 54 extends into the injector tube 52 through the opening of the air inlet baffle 53, spraying high-velocity gas to form a negative pressure, drawing air into the burner 5. Further, the housing 4 is provided with an adjustment hole 41 corresponding to the valve body 3. The mounting hole 31 is located inside the adjustment hole 41. The adjustment rod 2 can share the adjustment hole 41 with the valve body 3, avoiding additional openings on the housing 4, reducing processing costs, and improving the appearance.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
