Description

[Technical Field]

[0001] The present invention relates to cookware, and more particularly to smokeless cookware. [Background technology]

[0002] Some home cooking appliances, such as home roasters, allow food to be cooked while it is being eaten. When used in a dining room, a typical home electric roaster has a heat pipe for heating. When cooking food, oil from the food leaks and drips onto the heat pipe, generating a large amount of oil smoke. However, dining rooms generally do not have range hoods, and the oil smoke evaporates into the indoor environment, causing pollution. To address this issue, prior art deep-frying appliances have a oil smoke intake assembly on one side of the roaster and an exhaust port on the other side. The oil smoke intake assembly and the exhaust port form an air duct inside the roaster body and circulate air to the outside. However, because the oil smoke is located in the middle of the roaster where heat generation is high, the oil smoke spreads upward along with the hot steam from the food, and the oil smoke intake assemblies on the sides cannot fully absorb it, resulting in some oil smoke still spreading into the indoor environment. Furthermore, because the distance between the exhaust port and the oil smoke intake assembly is far, the oil smoke cannot fully enter the circulating air, resulting in a poor oil smoke purification effect.

[0064] As shown in Figures 1 to 11, an embodiment of the present invention provides a smokeless cooking appliance including a housing 1, an upper portion of which is provided an accommodating cavity 11, and two sides of which are provided with a first through hole 12 and a second through hole 13, a cooking assembly 4 mounted on the upper portion of the housing 1 and mounted within the accommodating cavity 11, the cooking assembly 4 including a heating plate 40, and two sides of which are provided with a first connection box 41 and a second connection box 42, respectively, a third through hole 411 at a position corresponding to the first through hole 12 of the first connection box 41, and a fourth through hole 421 at a position corresponding to the second through hole 13 of the second connection box 42.

[0065] The fan flue 2 is installed across the top of the cooking assembly 4, and the entire fan flue 2 has a linear, C-shaped hollow structure. Two partition plates 20 are installed inside the cross beams of the fan flue 2, and the two partition plates 20 divide the fan flue 2 into two spaces whose interiors do not communicate with each other. In the two spaces, fan mounting grooves 21 are installed corresponding to positions directly above the cooking assembly 4, and the fan mounting grooves 21 communicate with the interior of the fan flue 2. In the fan flue 2, a first downward air duct 25 and a second downward air duct 26 are provided facing downward on both sides of the two fan mounting grooves 21, and a smoke exhaust port is provided at the end of each of the first downward air duct 25 and the second downward air duct 26. A smoke suction device 5 is mounted in each of the two fan mounting grooves 21, and the exhaust ports of the two smoke suction devices 5 are connected to the smoke exhaust ports of the first downward air duct 25 and the second downward air duct 26, respectively. The smoke exhaust port of the first downward air duct 25 of the fan flue 2 is inserted into the third through-hole 411 of the second connection box 41, and the smoke exhaust port of the second downward air duct 26 of the fan flue 2 is inserted into the fourth through-hole 421 of the second connection box 42. To facilitate the installation of the smoke suction device 5, the fan flue 2 includes a flue body 22, a flue cover plate 23 removably attached to the bottom of the flue body 22, two partition plates 20 provided inside the flue body 22, and two fan mounting grooves 21 provided on either side of the two partition plates 20, smoke inlets 24 provided at positions corresponding to the two fan mounting grooves 21 on the flue cover plate 23, and first mesh filters 6 for absorbing oily smoke are removably attached to the openings of the two fan mounting grooves 21. The two first mesh filters 6 are fitted onto the edges of the smoke inlets 24, respectively.

[0066] The first mesh filter 6 includes a mesh filter frame 61, and a mating key 611 is provided at the upper end of the mesh filter 61. Correspondingly, a mating groove 241 is provided at the edge of the smoke inlet 24. Through the mating between the mating key 611 and the mating groove 241, the first mesh filter 6 and the flue cover plate 23 can be detachably fitted together. A ventilated filter net 62 is attached to the inside of the mesh filter frame 61, the center of the filter net 62 being recessed downward relative to the edge, and a mounting hole 63 is provided in the center of the filter net 62, within which an oil storage lid 64 is attached, with an edge 641 extending outward from the edge of the opening of the oil storage lid 64, the outer diameter of which is larger than the inner diameter of the mounting hole 63. Therefore, when the oil storage lid 64 is attached to the mounting hole 63 from above, the oil storage lid 64 fits into the mounting hole 63, and oil spilled from the surface of the filter net 62 is collected in the oil storage lid 64, preventing the oil from dripping onto the cooking assembly 4. Two protrusions 65 protruding outward are further provided on the bottom of the mesh filter frame 61 so that the first mesh filter can be rotated and fitted when attached.

[0067] As shown in FIG. 2, two air guide pipes 3 are attached to the lower part of the housing 1. As shown in FIG. 5, the air guide pipe 3 has an L-shaped structure and includes a duct main body 31 and a duct cover plate 32, with the duct cover plate 32 covering the upper part of the duct main body 31. An air intake port 35 is provided at one end of the air guide pipe 3, and the air intake ports 35 of the two air guide pipes 3 correspond to the positions of the first through-hole 12 and the second through-hole 13 of the housing 1 and communicate with them. As shown in FIG. 6, three air duct partition plates 33 are provided inside the duct main body 31 to divide the interior of the duct main body 31 into four air cavities 34, and the ends of the air cavities 34 are arranged sequentially along the length of the duct main body 31. When the pipe cover plate 32 covers the pipe body 31, an air inlet 35 is formed between one end of the pipe cover plate 32 and the pipe body 31, and four air outlets 36 are provided on the surface of the other end of the pipe cover plate 32, each corresponding to the end of an air cavity 34 inside the pipe body 31. Oil smoke enters the four air cavities 34 through the air inlet 35 of the air guide pipe 3, flows to the end of the air cavities 34, and is discharged from the air outlet 36 corresponding to each air cavity 34. Since multiple air outlets 36 are provided along the length of the pipe body 31, oil smoke inside the air guide pipe 3 is dispersed and discharged along the length.

[0068] A second mesh filter 37 is further attached inside the air guide pipe 3, and the second mesh filter 37 is attached to the air intake ports of the four air cavities 34 to filter the oily smoke sucked into the inside of the air guide pipe 3.

[0069] As shown in FIG. 3, smoke guide devices 14 are provided on both sides of the top surface of the housing 1 at positions corresponding to the exhaust ports 36 of the two air guide pipes 3, respectively. The smoke guide ports of the smoke guide devices 14 are arranged facing the smoke intake ports 24 of the fan flue 2, and are used to guide the oil smoke toward the smoke intake devices 5 and reduce the amount of oil smoke discharged into the room.

[0070] 8, both ends of the fan flue 2 communicate with the air guide pipe 3 via the first connection box 41 and the second connection box 42, respectively. When the smoke suction device 5 in the fan flue 2 is operating, the air below is sucked into the fan flue 2. On one side of the first connection box 41, the air is discharged into the air along paths a, b, c, d, e, f, g, h, and then sucked back into the smoke suction device 5 through the smoke guiding device 14, forming a circulation circuit for the oily smoke. Similarly, on one side of the second connection box 42, the air is discharged into the air along paths a'-b'-c'-d' and e'-f'-g'-h', and then sucked back into the smoke suction device 5 through the smoke guiding device 14, forming a circulation circuit for the oily smoke. 10, the air pressure inside the oil smoke circulation system is P1, and the air pressure outside the oil smoke circulation system is P2. Because the wind speed inside the oil smoke circulation system is faster than the wind speed outside the circulation system, the air pressure P2 outside the oil smoke circulation system is greater than the air pressure P1 inside the oil smoke circulation system, reducing the possibility of oil smoke spilling out. The smoke guiding devices 14 are arranged on both sides of the cooking assembly 4, sequentially from the first connection box 41 to the second connection box 42. An air flow forms a "curtain" between the smoke guiding devices 14 and the smoke suction device 5, and the pressure P2 outside the "curtain" is greater than the pressure P1 inside the "curtain," reducing the possibility of oil smoke inside the "curtain" spilling out.

[0071] 4, the cooking assembly 4 further includes a grill 43, which is disposed above the heating plate 40 and has a groove below it for fitting with the heat pipe of the heating plate 40. A circuit board is disposed inside the first connection box 41, and the circuit board is electrically connected to the smoke suction device 5 and the heating plate 40, respectively. The circuit board further includes an electrical connection interface for connecting to an external power source.

[0072] As shown in FIG. 2, an oil collection plate 8 is provided below the cooking assembly 4 to collect oil and foreign matter dripping from the heating plate 40. The oil collection plate 8 is mounted in the housing cavity 11, and an oil leakage screen 81 is provided in the middle of the oil collection plate 8. As shown in FIG. 11, the inner surface of the bottom of the oil collection plate 8 is inclined toward the oil leakage screen 81, which helps oil stains on the surface of the oil collection plate 8 to flow into the oil leakage screen 81. A sink 15 is provided on the upper surface of the housing 1 below the oil collection plate 8, and an oil storage box 9 is installed within the sink 15 to collect oil that has leaked from the oil collection plate 8. After the oil has accumulated in the oil storage box 9 for a certain period of time, it can be directly removed and cleaned, making cleaning easier. Two air guide pipes 3 are located on either side of the outer surface of the sink 15, making the internal structure more compact.

[0073] As shown in FIG. 2, the present invention further includes a base 7, which is fixedly connected to the bottom of the housing 1, and the sink 15 and the air guide pipe 3 of the housing 1 are accommodated inside the base 7.

[0074] Preferably, the smoke suction device 5 of the present invention uses a negative pressure blower.

[0075] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0076] 1. A fan flue 2 is installed above the cooking assembly 4, and the two lower connection ports of the fan flue 2 are respectively connected to the air guide pipe 3. The air guide pipe 3 has exhaust ports 36 installed on both sides of the upper surface of the cooking assembly 4. The oil smoke from the upper surface of the cooking assembly 4 is sucked in by the smoke suction device 5 in the fan flue and passes through the air guide pipe 3. The oil smoke from the exhaust port of the air guide pipe 3 is again sucked into the fan flue 2 by the smoke suction device 5, which circulates the oil smoke and reduces the oil smoke spilling out.

[0077] 2. The air guide pipe 3 is divided into a plurality of air cavities 34, and the exhaust ports 36 of each air cavity 34 are respectively arranged along the edge of the cooking assembly 4, forming a "curtain" at the edge of the cooking assembly 4, which can further reduce the oily smoke generated by the cooking assembly 4 from spilling out.

[0078] 3. A smoke guide device 14 is provided outside the exhaust port 36, with its smoke guide outlet facing the smoke inlet 24. The smoke guide outlet of the smoke guide device 14 guides the oil smoke discharge direction into the smoke inlet 24, which helps the oil smoke to be sucked back into the fan flue 2 and further reduces the oil smoke generated by the cooking assembly 4 from spilling out.

[0079] 4. A mesh filter for filtering oily smoke is installed at the smoke intake 24 of the fan flue to adsorb and filter oily smoke components, so that the oily smoke generated during the cooking process is adsorbed within the main body and the oily smoke emitted into the room is reduced. The mesh filter is also detachable, making it easy to clean and replace.

[0080] 5. An oil collecting plate 8 is provided below the heating plate 40 to collect oil and foreign matter that has fallen from the heating plate 40. A sink 15 is provided below the oil collecting plate 8 on the upper surface of the housing 1. An oil storage box 9 is installed inside the sink 15. After the oil has accumulated in the oil storage box 9 for a certain period of time, it can be directly removed and cleaned, making cleaning easy.

[0081] Compared with the prior art, the smokeless cookware of this invention is equipped with a double oil smoke filtering passage, which forms a circulation between the oil smoke outlet and the oil smoke inlet of the double oil smoke filtering passage, thereby realizing circulating filtration of oil smoke. In addition, the design of this invention forms a "curtain" between the exhaust port and the smoke inlet, which further reduces the possibility of oil smoke spilling out and improves the effectiveness of oil smoke absorption and filtering.

[0082] The above is only a preferred embodiment of the present invention, and does not limit the present invention. Those skilled in the art can make various modifications and changes to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
