This induction cooker achieves the purpose of oil fume filtration by utilizing the cooperation of the worm gear fan and the oil fume filter cotton blocks.

[0003] However, the above-mentioned induction cooker still has the following defects: the oil fume filter cotton block can only filter the grease in the oil fume. When consumers use the induction cooker to cook hot pot, the pot will produce a lot of water vapor, which will also contain a small amount of grease. The water vapor in the oil fume will eventually be discharged into the room. The water vapor floating upward will increase the moisture content of the indoor ceiling paint. After long-term use, it will cause the paint to peel off and affect the life of the ceiling.

[0004] Therefore, the applicant has improved and perfected the structure of the induction cooker, adding multi-functional features to the induction cooker and solving the above-mentioned problems, so that consumers can choose to use it. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned existing problems and provide a smoke extraction device for an induction cooker with a simple and reasonable structure.

[0006] A fume extraction device for an induction cooker includes an induction cooker body. The induction cooker body contains a heating coil and a control system electrically connected to the heating coil. A heating support area is located on the top of the induction cooker body corresponding to the heating coil. A fume extraction device is located on one side of the induction cooker body near the heating support area. The fume extraction device includes a fume extraction assembly and a support column. The fume extraction assembly is connected to the top of the support column. A filter duct is provided within the fume extraction assembly. A metal filter screen for condensing water vapor is provided at the air intake or, possibly, the air outlet of the filter duct.

[0007] The objective of this utility model can also be achieved by the following technical measures:

[0008] As a more specific embodiment, the support column is provided with a downward-flowing drainage channel, the bottom of the smoke extraction assembly is provided with a rear drain outlet connected to the drainage channel, and the induction cooker body is provided with a water collection box located below the drainage channel.

[0009] As a further embodiment, the smoke extraction assembly includes a housing and two fans. The housing defines a filter duct for straight-flow airflow, and the two fans are arranged side-by-side within the housing. The housing is inclined, with the air intake facing the heating support area and lower than the air outlet. A front metal filter is detachably connected to the air intake, and a rear metal filter is detachably connected to the air outlet.

[0010] As a further embodiment, both the front and rear metal filters include a metal frame, and the metal frame contains multiple parallel metal horizontal grilles.

A front drain outlet is provided at the bottom of the water collection trough, and a drainage component connecting the water collection trough and the drainage channel is provided between the front drain outlet and the support column.

[0012] As a further embodiment, the bottom of the front metal filter screen extends with an inner drain nozzle corresponding to the front drain outlet, and the side wall of the support column is provided with a side water inlet that connects to the drainage channel. The side water inlet extends with an outer water inlet that connects to the inner drain nozzle. The outer water inlet and the inner drain nozzle cooperate to form a drainage component.

[0013] As a further embodiment, the support column is provided with two spaced drainage channels, which together enclose a lead wire groove.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] See Figures 1 to 6 As shown, an induction cooker includes an induction cooker body 1. The induction cooker body 1 has a heating coil and a control system electrically connected to the heating coil. The top of the induction cooker body 1 has a heating support area 2 corresponding to the heating coil. The induction cooker body 1 has a smoke extraction device 3 on one side of the heating support area 2. The smoke extraction device 3 includes a smoke extraction assembly 5 and a support column 6. The smoke extraction assembly 5 is connected to the top of the support column 6. The smoke extraction assembly 5 has a filter duct 301. The filter duct 301 has a metal filter screen for condensing water vapor at the air intake 302 or, if it also includes, the air outlet 303.

[0028] During use, water vapor is drawn into the filter duct 301 and comes into contact with the low-temperature metal filter screen. This causes the water vapor to cool down and condense into water droplets on the metal filter screen, which are then collected and treated. The water droplets also absorb at least some of the grease, thus enabling the induction cooker to achieve smokeless and water vaporless exhaust. The smoke extraction device with this structure is compact and operates quietly, reducing the amount of water vapor floating to the ceiling and thus minimizing the lifespan of the ceiling paint.

[0029] Furthermore, the metal filter screen can be quickly disassembled and cleaned after use, keeping the fumigation device 3 clean and preventing grease from adhering to the surface of the metal filter screen, which would prevent water vapor from contacting the surface of the metal filter screen and reduce condensation efficiency.

[0030] The smoking device 3 is connected to the rear side of the induction cooker body 1 located in the heating support area 2. The induction cooker body 1 located in the front side of the heating support area 2 is provided with a control panel 13 and / or a control knob 14.

[0031] The support column 6 has a downward-directing drainage channel 601, the bottom of the smoke extraction assembly 5 has a rear drain outlet 501 that connects to the drainage channel 601, and the induction cooker body 1 has a water collection box 7 located below the drainage channel 601.

[0032] The smoke extraction assembly 5 cools water vapor through a metal filter, causing it to condense into water droplets. These droplets fall to the bottom of the filter duct 301 and then flow into the water collection box 7 through the rear drain outlet 501 and drain channel 601. This allows consumers to conveniently collect and dispose of the condensate after using the induction cooker. The water collection box 7 is located inside the induction cooker body 1. Using a larger water collection box 7 avoids the support column 6 becoming too large due to the water collection box 7, which would occupy the limited space on the top surface of the induction cooker body 1. In other embodiments, the water collection box 7 can also be located at the lower part of the support column 6, which helps to reduce the width and height of the induction cooker body 1.

[0033] The smoke extraction assembly 5 includes a housing 51 and two fans 52. The housing 51 defines a filter duct 301 for straight airflow. The two fans 52 are arranged at left and right intervals inside the housing 51. The housing 51 is inclined, with the air intake 302 facing the heating support area 2 and lower than the air outlet 303. A front metal filter 53 is detachably connected to the air intake 302, and a rear metal filter 54 is detachably connected to the air outlet 303.

[0034] The width of the outer shell 51 is preferably adapted to the heating support area 2. Therefore, two or more fans 52 need to be arranged inside the outer shell 51 so that the suction of the smoke assembly 5 can be evenly distributed along the width direction. When the fan 52 is working, it draws outside air into the filter duct 301. The flowing space can remove the heat from the front metal filter screen 53 and the rear metal filter screen 54, keeping them at a low temperature. At the same time, water vapor in the air flows through the surfaces of the front metal filter screen 53 and the rear metal filter screen 54, causing the water vapor to cool down and condense into water droplets.

[0035] Water vapor is mainly cooled by the front metal filter 53, while the rear metal filter 54 plays an auxiliary role in condensation. Therefore, in other embodiments, the rear metal filter 54 can be replaced by a protective grille or other types of filter made of other materials or with other structures.

[0036] Both the front metal filter 53 and the rear metal filter 54 include a metal frame 531. The metal frame 531 contains multiple parallel metal horizontal grilles 532. These horizontal grilles 532 are arranged at an angle, and the inner side of each horizontal grille 532 is lower than its outer side (e.g., ...). Figure 5 (As shown in the figure). The metal filter screen of this structure ensures that after water droplets form on the surface of the metal horizontal grille 532, the water droplets can only flow into the filter air duct 301, preventing the water droplets from flowing out and causing water leakage in the smoke extraction assembly 5.

[0037] The outer casing 51 extends a water-blocking ring 511 from the inner peripheral wall of the air intake 302. The front metal filter screen 53 is located in front of the water-blocking ring 511, and a water collection groove 512 is formed between its metal outer frame 531 and the water-blocking ring 511. A front drain outlet 515 is provided at the bottom of the water collection groove 512. A drainage component connecting the water collection groove 512 and the drainage channel 601 is provided between the front drain outlet 515 and the support column 6.

[0038] The bottom of the front metal filter screen 53 extends an inner drain nozzle 533 corresponding to the front drain outlet 515. The side wall of the support column 6 is provided with a side water inlet 602 that connects to the drainage channel 601. The side water inlet 602 extends an outer water inlet 61 that connects to the inner drain nozzle 533. The outer water inlet 61 and the inner drain nozzle 533 cooperate to form a drainage component.

[0039] The water-blocking ring 511 can limit the depth of the front metal filter 53 inserted into the air intake 302. The metal outer frame 531 includes a bottom frame and a front frame wall connected to the front side of the bottom frame. The water-blocking ring 511 serves as the rear frame wall. Thus, the bottom frame, the front frame wall, and the rear frame wall together enclose and limit the water collection groove 512. The water droplets on the metal horizontal grille 532 can only drip into the water collection groove 512. This eliminates the need for a sealing structure in the gap between the front metal filter 53 and the outer casing 51. After the water droplets in the water collection groove 512 flow out, they flow along the connected inner drain nozzle 533 and the outer water nozzle 61, and finally flow into the drainage channel 601 through the side water inlet 602 (the water droplet flow path of the front metal filter 53 is shown by the grid arrow in the attached figure).

[0040] The rear metal filter 54 is placed therein. The inner peripheral wall of the outer shell 51 also extends with a number of spaced limiting ribs 514. One end of the limiting rib 514 is connected to the water-blocking ring 511 to improve the strength of the water-blocking ring 511. The other end of the limiting rib 514 is used to limit the rear metal filter 54 and restrict the depth of the rear metal filter 54 into the air outlet 303. The water droplets flowing out of the rear metal filter 54 will drip directly onto the bottom of the outer shell 51. Since the outer shell 51 is set at an angle, the water droplets will flow towards the water-blocking ring 511. The water-blocking ring 511 can also intercept this part of the condensate. The rear drain 501 is set between the water-blocking ring 511 and the rear metal filter 54. Therefore, this part of the condensate flows into the drain channel 601 through the rear drain 501 (the water droplet flow path of the rear metal filter 54 is shown by the black arrow in the attached figure).

[0041] In this embodiment, the front metal filter 53 and the rear metal filter 54 have the same structure, allowing consumers to easily reassemble them at the air intake 302 and air outlet 303 after disassembly and cleaning, without having to spend time comparing and reassembling them. The inner drain nozzle 533 on the front metal filter 53 can protrude from the outer shell 51 to cooperate with the external water nozzle 61, but the rear metal filter 54 is completely connected inside the air outlet 303. Therefore, the outer shell 51 is provided with a limiting groove 513 that cooperates with the inner drain nozzle 533. The cooperation between the inner drain nozzle 533 and the limiting groove 513 can also limit and fix the bottom of the rear metal filter 54.

[0042] The support column 6 is provided with two spaced drainage channels 601, and the two drainage channels 601 enclose and define a lead wire groove 65. The top of the lead wire groove 65 is provided with a lead wire opening 651. The bottom of the outer shell 51 is provided with a wire guide tube 613. The lower part of the wire guide tube 613 is inserted into the lead wire opening 651, and the upper part of the wire guide tube 613 is placed in the filter air duct 301 and is at least higher than the rear drain outlet 501.

[0043] This structure separates the condensate from the lead wire groove 65 to prevent short circuits or electrical leakage caused by water leakage. Since the condensate generated by the rear metal filter screen 54 flows into the bottom of the outer casing 51, the upper part of the conduit 613 is higher than the main drain outlet 501, which can prevent the condensate in this part from flowing into the lead wire groove 65 through the conduit 613, thus also preventing water leakage.

[0044] like Figure 7 As shown, the rear end of the induction cooker body 1 is recessed into a cavity 102, and the water collection box 7 is slidably connected to the cavity 102. The cavity 102 is provided with an insertion through hole, and the bottom end of the support column 6 is connected to the insertion through hole, so that the drainage channel is directly connected to the water collection box.

[0045] A positioning sensor connected in series with the control system is provided on the rear side of the accommodating cavity 102. The water collection box 7 is provided with a sensing structure that cooperates with the positioning sensor. The control system senses whether the water collection box 7 is pushed in place through the positioning sensor to start or stop the working circuit of the smoking device 3. This structure prevents the smoking device 3 from being started when the water collection box 7 is not installed, causing condensate water to flow directly into the accommodating cavity 102 and increasing the cleaning burden on consumers.

[0046] The positioning sensor is a magnetic sensor; the magnetic sensor includes a Hall switch or a reed switch 11, and the sensing structure includes a magnet block 12 connected to the rear wall of the water collection box 7. After the water collection box 7 is fully pushed into place, the magnet block 12 forms a magnetic interaction with the Hall switch or the reed switch 11.

[0047] Alternatively, the positioning sensor is a micro switch, and the sensing structure is the rear wall of the water collection box 7. After the rear wall of the water collection box 7 is pushed into place, it presses against the on / off switch of the micro switch to form a dynamic contact.

[0048] In this embodiment, the front metal filter 53 or the rear metal filter 54 can be installed at the air intake 302 or the air outlet 303 respectively by interference fit. Of course, a first magnet block 55 can be added to the top surface of the front metal filter 53 or the rear metal filter 54, and a second magnet block (not marked in the figure) can be added at the air intake 302 or the air outlet 303. By using the cooperation of the first magnet block 55 and the second magnet block, the front metal filter 53 or the rear metal filter 54 can be magnetically fixed at the air intake 302 or the air outlet 303.

[0049] In addition, to facilitate the installation and removal of the front metal filter 53 or the rear metal filter 54, the front sides of the front metal filter 53 and the rear metal filter 54 are also connected to a pull tab 57.

[0050] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
