[0002] As a popular traditional food, hot pot produces a lot of fumes and odors during cooking. If these fumes and odors are not properly handled, they will affect the indoor air quality and may also pose a potential threat to consumers' health. With the improvement of environmental awareness and the pursuit of a healthy lifestyle, the traditional hot pot dining method urgently needs to be improved to reduce the impact of fumes on the environment and human body. Therefore, an induction cooker hot pot table with integrated smoke removal and purification function came into being to solve this problem. This hot pot table not only provides traditional hot pot cooking functions, but also effectively removes fumes and odors through a built-in purification system, thereby improving the dining environment and enhancing customers' dining experience.

[0003] Hot pot cooking usually involves heating oil at high temperatures. When the oil is heated above the smoke point, it produces oil smoke, which contains tiny droplets of oil. In addition, when the ingredients are cooked in the hot pot, some food fragments may carbonize or decompose due to the high temperature, forming solid particles, which are released into the air along with the oil smoke. Currently, many hot pot tables can only perform preliminary purification of the oil smoke produced. Preliminary purification not only has poor results but also wastes materials and increases costs.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0028] Example 1

[0029] The present embodiment provides a smoke removal and purification hot pot table with a multi-layer filtering structure, comprising a table top, a table box, a smoke exhaust mechanism and a purification box.

[0030] refer to Figure 1-Figure 3 In this embodiment, the table top 1 is provided with an opening for placing the pot body 9 in the middle, and the opening is a circular opening. The circular opening is covered with an exhaust hood 4 around the periphery, and the exhaust hood 4 is also a circular exhaust hood 4, wherein the exhaust hood 4 is provided with a plurality of exhaust holes around the periphery, and the plurality of exhaust holes are arranged alternately. The alternate arrangement of the exhaust holes can ensure uniform distribution of exhaust air, and the problem of uneven exhaust air caused by too large or too small intervals between the exhaust holes can be avoided by alternate arrangement, so that the oil smoke can be evenly sucked into the exhaust hood 4, and the alternate arrangement of the exhaust holes can also increase the oil smoke capture area of ​​the exhaust hood 4, so that the exhaust hood 4 can cover a wider area, and improve the efficiency of adsorbing and removing oil smoke. In addition, the exhaust holes can be arranged alternately to reduce the resistance of the air duct. When the oil smoke is discharged through the exhaust holes, the alternately arranged exhaust holes can reduce the obstruction of the air flow, making the exhaust air more smooth and reducing the pressure loss of the exhaust system.

[0031] The exhaust hood 4 used in this embodiment is cast by an integrated mold, and the material is ABS plastic. Compared with the traditional sheet metal welded exhaust hood 4, this design shows significant advantages in many aspects, including: the exhaust hood 4 formed in one piece has no welding seams, and the overall structure is more solid and stable, which can withstand the wear and impact in daily use and extend the service life. The ABS material cast by the mold makes the exhaust hood 4 smooth, not easy to accumulate oil and food residues, and easy to clean and maintain. The ABS material is easy to process and shape, so that the design of the exhaust hood 4 can be more delicate and complex, meeting the diverse design requirements. ABS plastic has good heat resistance, can remain stable in a high temperature environment, and is suitable for the use of cooking equipment such as hot pot tables. Compared with traditional metal materials, ABS plastic has strong corrosion resistance to chemical substances such as acids and alkalis, and is not easy to rust or corrode. The exhaust hood 4 made of ABS material is lighter than the exhaust hood 4 welded by sheet metal, which is easy to install and carry, and reduces the weight of the overall hot pot table. ABS plastic has good electrical insulation, which can protect users from the risk of electric shock from electrical equipment such as induction cookers 12.

[0032] In this embodiment, the table top 1 is fixedly connected to the table box 2 by welding. The inside of the table box 2 is provided with an induction cooker 12, a first filter device 7, a second filter device 7 and a smoke exhaust mechanism 10 from top to bottom. The purification box 3 is provided on one side of the table box 2.

[0033] refer to Figure 4The first filter device 7 used in this embodiment includes a filter frame 701 and a composite filter layer. Since the table box 2 is a trapezoidal structure, the filter frame 701 can be stuck in the table box 2 with a trapezoidal structure. The composite filter layer is arranged in the filter frame 701, wherein the composite filter includes a fiber mesh layer and an activated carbon layer. The fiber mesh layer is composed of a coarser fiber mesh layer to form a pre-filter layer for capturing large particles of impurities and dust to extend the service life of other filter layers, and a medium-efficiency filter layer is composed of a finer fiber mesh layer to capture smaller particles.

[0034] In a preferred embodiment, the composite filter layer is a HPEA filter, which is made of a special electrostatic material and has a high-efficiency electrostatic adsorption performance. It can capture smaller particles, such as bacteria and harmful chemicals, and is used for the first layer of oil fume filtration and air purification.

[0035] The activated carbon layer is used to absorb gaseous harmful substances and odors, such as volatile organic compounds and odors in oil smoke. Specifically, the fiber mesh layer is arranged on the top of the filter frame 701 and close to the smoke outlet, and the activated carbon layer is arranged on the bottom of the filter frame 701 and close to the second filter device 7.

[0036] refer to Figure 5 The second filtering device 7 used in this embodiment includes a filtering box 801, a pressing plate, oil-absorbing cotton, an activated carbon block, and activated carbon cotton. The top of the filtering box 801 is provided with an opening, and the bottom is set to be hollow. In this embodiment, the bottom is set to be hollow, that is, a grid structure, and the grid structure is used for air leakage. The activated carbon cotton is laid in the hollow at the bottom of the filtering box 801. The hollow design of the bottom can place the activated carbon cotton at the very bottom, effectively utilizing the entire height of the filtering box 801, increasing the surface area for adsorbing oil smoke, and improving the purification efficiency.

[0037] An activated carbon block is placed on the top of the activated carbon cotton, and the activated carbon blocks are evenly arranged on the activated carbon cotton. The activated carbon block has a large specific surface area and pore structure, and can more effectively adsorb organic gases and odor substances in the air. Placing the activated carbon block on the top of the activated carbon cotton can increase the adsorption capacity of the entire filter layer and improve the purification effect. At the same time, adding the activated carbon block can share the adsorption burden of the activated carbon cotton and reduce the adsorption saturation rate of the activated carbon cotton, thereby extending the service life of the filter device, reducing the frequency of replacing the filter material, and reducing maintenance costs. The activated carbon block in this embodiment is a honeycomb structure. The honeycomb structure provides a large surface area, which makes it have good sound absorption performance. When air passes through the activated carbon block, the sound waves will be repeatedly reflected and absorbed in its tiny pores, thereby weakening the propagation and diffusion of the sound and reducing the noise level when the fan is working.

[0038] The activated carbon block is paved with oil-absorbing cotton on top. Activated carbon is mainly used to absorb gaseous organic matter and odor, not liquid grease. Therefore, placing the oil-absorbing cotton on the activated carbon layer can prevent oil stains from directly contacting the activated carbon, and avoid the pollution of grease from affecting the adsorption effect of the activated carbon. As an oil-absorbing material, the oil-absorbing cotton can effectively absorb grease particles. Placing the oil-absorbing cotton on the activated carbon layer can remove the grease particles in the oil smoke before it passes through the activated carbon layer, reduce the burden on the activated carbon, and improve its efficiency in adsorbing gaseous organic matter.

[0039] A pressure plate is provided on the top of the oil-absorbing cotton. The pressure plate is a hollow structure, which is also a grid structure. The pressure plate is located on the top of the filter device and is used to fix and compact the filter material to ensure that the filter material is firmly fixed in place to avoid loosening or falling off during operation. Both sides of the pressure plate are threadedly connected to the inner wall of the filter box 801 to achieve fixation.

[0040] This embodiment proposes a preferred method that the inner wall of the table box 2 is provided with a slide groove, and the outer wall of the filter box 801 in the second filter device 7 is provided with a slider, and the slider is adapted to the slide groove to realize the sliding connection of the filter box 801 to the table box 2. The dynamic connection allows the filter box 801 to slide out of the table box 2 easily, which is convenient for maintenance, cleaning and replacement of filter materials of the filter device, which can reduce the workload of maintenance personnel and improve maintenance efficiency. It should be clear that since the second filter device 7 is movably connected to the table box 2, screws are also required to fix the second filter device 7 to the table box 2 to prevent the second filter device 7 from sliding at will during the use of the hot pot table.

[0041] A preferred method is to further include a table frame 5, a stove frame 6 and a control motherboard 11, wherein the table frame 5 is fixed to the outer edge of the top of the table box 2 by screws, and the table board 1 is fixed by adding the table frame 5, so that the table frame 5 serves as a connecting structure between the table board 1 and the table box 2, providing additional support and stability. This design can disperse pressure and weight, and reduce deformation or damage of the table board 1 when it is in direct contact with the table box 2. In addition, the table frame 5 can play a certain shock-absorbing role, especially in scenarios such as hot pot tables that need to withstand heat sources and heavy objects, the table frame 5 can absorb and disperse vibrations caused by heating of the pot body 9 or other activities, thereby protecting the table board 1 and the table box 2.

[0042] The table frame 5 used in this embodiment is an H-shaped table frame 5. The H-shaped table frame 5 provides good lateral and longitudinal stability, can bear more weight and resist twisting or bending. In addition, the H-shaped table frame 5 occupies a smaller floor area, providing more leg room for customers, making seating arrangements more flexible and improving space utilization efficiency.

[0043] The cross beams of the table frame 5 are respectively provided with fixings, the table top 1 is fixed to the fixings of the cross beams of the table frame 5 by screws, the stove frame 6 is composed of an outer shell and a bracket, the bottom of the outer shell is connected to the exhaust mechanism by the bracket, the outer wall of the outer shell of the stove frame 6 is fixed to the inner wall of the table box 2 by screws, the outer shell is a semi-closed outer shell, and the four corners of the top surface of the outer shell are respectively provided with smoke exhaust ports, the inner part of the outer shell of the stove frame 6 is provided with the induction cooker 12, the induction cooker 12 is electrically connected to the control main board 11, and the control main board 11 is arranged at the bottom of the table box 2.

[0044] The present embodiment proposes a smoke exhaust mechanism 10 including a mixed flow fan and a flue, wherein the mixed flow fan is threadedly connected to the bottom of the table box 2, and the mixed flow fan is connected to the purification box 3 through the flue, and the purification box 3 is detachably connected to the table box 2. Since the working principle of the mixed flow fan is between that of the axial flow fan and the centrifugal fan, the mixed flow fan has the characteristics of large air volume and low noise of the axial fan, and the static pressure capacity of the centrifugal fan.

[0045] Therefore, the airflow generated by the mixed flow fan is a composite airflow with both axial and radial directions. The characteristics of this composite airflow make the air outlet structure of the mixed flow fan relatively free. The air outlet of the mixed flow fan is directly facing the area where exhaust is required. Since the air outlet of the mixed flow fan is not restricted by a specific air duct, it can be installed and arranged more flexibly. It does not require a complex air duct system and can directly discharge the air, which makes the application of the mixed flow fan in the hot pot table more convenient and effective.

[0049] The multi-layer filter block is composed of a honeycomb activated carbon layer and a composite filter layer fixed in sequence, which is used for preliminary filtration and adsorption of pollutants in the air. The composite filter layer faces the air outlet and effectively captures larger particles and dust; the activated carbon layer uses its porous structure to absorb harmful gases and odors.

[0050] The metal louver layer covers the surface of the activated carbon layer to protect the activated carbon layer from damage and plays a certain structural support role.

The honeycomb activated carbon layer and the composite filter layer are responsible for filtering and adsorbing pollutants in the air; the metal louver layer protects the activated carbon layer and guides the airflow; the windless component layer further breaks up the wind flow through a variety of materials and structures, reducing the wind feeling while continuing to filter the air.
