Description

Technical Field

[0001] This utility model relates to the field of kitchenware smoke testing, and in particular to a shielding device and a smoke testing device. Background Technology

[0002] In related technologies, during the smoke generation test of range hoods, in order to better reflect the actual cooking scenarios of users, soy sauce or water is added to the oil pan during the test. This ensures that a large amount of smoke is generated to test the smoke extraction effect of the range hood. However, when soy sauce or water is added to the oil pan, oil splatters out while generating smoke, which not only pollutes the test environment but also quickly consumes test consumables, leading to an increase in the cost of smoke generation testing.

[0006] According to the shielding device of this application, by adopting a multi-layer test plate structure spaced apart in the thickness direction, and setting smoke leakage holes and shielding parts that at least partially overlap with the smoke leakage holes in the projection on two adjacent test plates, a shielding barrier that allows smoke to flow is formed. On the one hand, it can ensure that the smoke can escape smoothly through the smoke leakage holes, ensuring the normal conduct of the smoke test. On the other hand, it can effectively block cooking consumables that are splashed due to heating by means of the multi-layer plate and the shielding parts that overlap in the projection, greatly reducing the splashing and consumption of materials during the test, thereby directly reducing the cost of the smoke test.

[0019] The following is for reference. Figures 1-6 Description of a shielding device 100 according to an embodiment of the present invention.

[0020] The shielding device 100 according to this application includes: a test disc body, the test disc body being configured to be two or more spaced apart in the thickness direction, wherein in two adjacent test disc bodies, the smoke leakage hole on one of the test disc bodies is correspondingly provided with the shielding part on the other test disc body.

[0021] The shielding device 100 consists of two or more test plates spaced apart in the thickness direction. The interlayer gaps create a buffer space, slowing the rise of the smoke and preventing cooking consumables (such as oil and water) from splashing out due to violent boiling, thus reducing spillage and lowering material consumption costs during testing. In two adjacent test plates, one has a smoke vent, and the other has a shielding part 122, with their projections in the thickness direction at least partially overlapping. This design ensures that smoke can escape normally through the smoke vent without affecting smoke generation during the smoke test, while the shielding part 122 physically shields the area above the smoke vent, effectively preventing splashed cooking consumables from directly spilling out of the device. The overlapping projections of the shielding part 122 and the smoke vent in the vertical direction form a staggered shield, achieving multi-stage blocking of splashes without significantly hindering smoke flow, improving shielding efficiency, and preventing smoke accumulation or pressure increase due to complete blockage, thus ensuring the stability of the testing environment.

[0022] According to the shielding device 100 of this application, by adopting a multi-layer test plate structure spaced apart in the thickness direction, and by providing smoke leakage holes and shielding parts 122 that at least partially overlap with the smoke leakage holes in projection on two adjacent test plates, a shielding barrier that allows smoke to flow is formed. On the one hand, it can ensure that the smoke can escape smoothly through the smoke leakage holes, ensuring the normal conduct of the smoke test. On the other hand, it can effectively block cooking consumables that are splashed due to heating by means of the multi-layer plate and the shielding parts 122 that overlap in projection, greatly reducing the splashing and consumption of materials during the test process, thereby directly reducing the cost of the smoke test.

[0023] According to some embodiments of this application, in two adjacent test discs, the lower disc is the first disc 11 and the upper disc is the second disc 12. The first disc 11 has a first smoke leakage hole 111 and a first shielding portion 112 that extend through in the thickness direction. The second disc 12 is disposed on one side of the first disc 11 in the thickness direction. A second smoke leakage hole 121 is formed on the second disc 12, and the second smoke leakage hole 121 is staggered with the first smoke leakage hole 111. A second shielding portion 122 is formed on the second disc 12, and the projection of the second shielding portion 122 and the first smoke leakage hole 111 in the thickness direction at least partially overlaps. The projection of the first shielding portion 112 and the second smoke leakage hole 121 in the thickness direction at least partially overlaps.

[0024] In this embodiment, a first smoke-leaking hole 111 extending through the thickness direction is formed in the first disc 11 for the initial passage of smoke. A second disc 12 is disposed on one side of the first disc 11 in the thickness direction, and a second smoke-leaking hole 121 is formed on the second disc 12. The second smoke-leaking hole 121 and the first smoke-leaking hole 111 are staggered, forming a meandering channel for the smoke, which can effectively slow down the upward flow velocity of the smoke. The second blocking portion 122 formed on the second disc 12 at least partially overlaps with the projection of the first smoke-leaking hole 111 on the first disc 11 in the thickness direction. The second blocking portion 122 directly covers the first smoke-leaking hole 111, preventing smoke from escaping through the first smoke-leaking hole 111. The splashed cooking materials are trapped on the surface of the first plate 11 or between the two plates, greatly reducing the loss of materials due to splashing. The splashed materials can flow back into the pot through the first smoke vent 111. The projection of the second smoke vent 121 on the second plate 12 in the thickness direction at least partially overlaps with the first shielding part 112. The first shielding part 112 directly covers the bottom of the second smoke vent 121, which can block the cooking materials splashing up from the bottom and trap them on the surface of the second plate 12, greatly reducing the loss of materials due to splashing.

[0025] The second smoke vent 121 is staggered with the first smoke vent 111, ensuring that the smoke has a dedicated escape path. After passing through the first smoke vent 111, the smoke can diffuse laterally and continue to rise through the second smoke vent 121, making the smoke diffusion more uniform and allowing for a more realistic simulation of smoke diffusion.

[0026] According to some embodiments of this application, the first smoke leakage holes 111 are configured as a plurality of spaced-apart holes on the first disc body 11, and the plurality of first smoke leakage holes 111 are configured as arc-shaped holes arranged around the center of the first disc body 11, and the plurality of arc-shaped holes are spaced-apart in the circumferential and / or radial directions; the second smoke leakage holes 121 are configured as a plurality of spaced-apart holes on the second disc body 12, and the plurality of second smoke leakage holes 121 are configured as arc-shaped holes arranged around the center of the second disc body 12, and the plurality of arc-shaped holes are spaced-apart in the circumferential and / or radial directions.

[0027] The first smoke-leaking holes 111 are configured as multiple spaced-apart holes on the first plate 11. These multiple first smoke-leaking holes 111 are arc-shaped holes arranged around the center of the first plate 11 and spaced apart circumferentially and / or radially. Correspondingly, the second smoke-leaking holes 121 are also configured as multiple spaced-apart arc-shaped holes on the second plate 12, similarly arranged around the center of the second plate 12 and spaced apart circumferentially and / or radially. By designing the smoke-leaking holes as multiple arc-shaped holes around the center of the plate and spaced apart circumferentially and radially, the shielding range of the shielding device 100 can fully cover the heating area of ​​the cookware, ensuring that no matter which direction the cooking consumables splatter from, they can be effectively intercepted by the upper second shielding part 122, significantly improving the comprehensiveness and reliability of the shielding.

[0028] Furthermore, the staggered arc-shaped holes provide multiple evenly distributed meandering paths for the rising fumes. After being generated from the central heating area at the bottom, the fumes can diffuse evenly in all directions and rise layer by layer through the arc-shaped holes at different radial positions. This design avoids the fumes from rushing out rapidly from a single channel, making their flow smoother and more dispersed. This helps to realistically simulate the diffusion state of fumes in an actual cooking environment, while further reducing the possibility of splashing flammable materials from the bottom.

[0029] According to some embodiments of this application, the shielding device 100 further includes a first support member 13, which is disposed at the bottom of the lowest test pan, or at the bottom of the first pan 11. The first support member 13 can optionally extend radially outward. Extending downward from the bottom of the first pan 11, the first support member 13 effectively adds a support base to the shielding device 100. When it extends radially outward, it significantly increases the bottom support area of ​​the device, reducing the risk of the entire device tilting or slipping on the platform, and improving safety and stability during testing. The optional extension of the first support member 13 enhances the adaptability of the shielding device 100. The extension or retraction of the support member allows the shielding device 100 to be supported on cookware or heating platforms of different diameters, improving the versatility and flexibility of the shielding device 100.

[0030] According to some embodiments of this application, the first support member 13 is rotatably disposed on the test pan body. In some specific embodiments, the first support member 13 is rotatably disposed on the first pan body 11. The rotation axis 132 of the first support member 13 is perpendicular to the first pan body 11. The first support member 13 has an abutment portion 131 protruding radially on the rotation axis 132. The first support member 13 can be rotated to selectively protrude the abutment portion 131 beyond the outer periphery of the first pan body 11. The abutment portion 131 can be controlled to protrude or retract by rotation, which is simple to operate. When the abutment portion 131 is rotated and protrudes, the abutment portion 131 acts as a fulcrum, expanding the effective support diameter of the bottom of the first pan body 11, so that it can be stably mounted on the rim of pots of different sizes, effectively preventing the risk of the entire device tipping over due to instability and enhancing the safety of the testing process.

[0031] According to some embodiments of this application, the shielding device 100 further includes a second support member 14, which is disposed between two adjacent test discs. In a specific embodiment, it may be disposed between the first disc 11 and the second disc 12 to space them apart. The second support member 14 provides structural support between the first disc 11 and the second disc 12, ensuring uniformity of the gap between the two disc layers. This ensures that the dimensions of the flue gas flow channel and the shielding space are constant, standardizing the test conditions and improving the comparability and repeatability of test results from different batches. The second support member 14 connects the first disc 11 and the second disc 12, acting as a support column and enhancing the overall rigidity and stability of the multi-layer disc structure.

[0032] According to some embodiments of this application, the first support member 13 and the second support member 14 are arranged facing each other in the thickness direction. The first support member 13 and the second support member 14 are also facing each other in the vertical direction, so that the pressure transmitted from above and the supporting reaction force from the bottom can be transmitted along a continuous, vertical path. The aligned design of the first support member 13 and the second support member 14 avoids the generation of bending moments or torques within the disc body due to stress, effectively preventing relative displacement or tilting between the two disc bodies when heated or compressed, thereby ensuring the spacing between them, guaranteeing the stability of the flue gas buffer space and shielding effect, and ensuring consistent test conditions.

[0033] According to some embodiments of this application, the shielding device 100 further includes a fixed shaft 15, which sequentially passes through the second disc 12, the second support member 14, the first disc 11, and the first support member 13 in the thickness direction. The first support member 13 rotates around the fixed shaft 15. The fixed shaft 15 passes through the second disc 12, the second support member 14, the first disc 11, and the first support member 13 from top to bottom, so that the second disc 12, the second support member 14, the first disc 11, and the first support member 13 are connected in series to form a compact and stable whole. This not only simplifies the assembly process, but more importantly, ensures the coaxiality and relative positional accuracy of each component in the thickness direction. The fixed shaft 15 provides a stable rotation axis for the rotation of the first support member 13, ensuring that the first support member 13 and its abutment portion 131 can rotate smoothly and stably, achieving reliable unfolding and retraction, and avoiding instability caused by shaft wobbling or offset.

[0034] In some embodiments, a plurality of first support members 13 may be linked together to be adapted to rotate synchronously for deployment and retraction.

[0035] According to some embodiments of this application, the fixed shaft 15, the first support member 13, and the second support member 14 are configured as multiple, corresponding one-to-one, and arranged at intervals on the outer periphery of the first disk 11. Multiple support points are evenly distributed circumferentially, jointly bearing the upper structure and external loads. This allows the force on the shielding device 100 to be evenly distributed across multiple support points, effectively avoiding stress concentration or overturning risks that may occur with single-point support. Multiple sets of through fixed shafts 15 tightly connect the upper and lower disks and interlayer supports, forming an integral frame structure, which greatly enhances the shielding device 100's ability to resist thermal and physical deformation.

[0036] The smoke testing apparatus 200 according to this application is briefly described below.

[0037] like Figure 6 As shown, the smoke testing device 200 according to this application includes a pot body 20 and a shielding device 100. The shielding device 100 is disposed on the pot body 20 and is configured as any of the shielding devices 100 described in the above embodiments. Because the smoke testing device 200 of this application is equipped with a shielding device 100, the consumption of cooking consumables is reduced, thus lowering the cost of smoke testing.
