Description

Technical Field

[0001] The present application relates to the technical field of kitchen equipment, and in particular to a frying and grilling equipment. Background Art

[0002] Frying and baking equipment will produce a lot of oil smoke in the process of frying and baking food. As a mixed pollutant, oil smoke is a very complex aerosol composed of gas, solid and liquid phases, and will change with the type of food and cooking conditions. The intermediate or final products produced in the reaction process will also undergo secondary reactions due to interaction, which will pollute the kitchen environment and even affect the health of users. Therefore, how to deal with the oil smoke generated during the operation of smart frying and baking rice cookers has become an urgent problem to be solved in the application of smart rice cookers.

[0003] The existing patent with announcement number CN220417389U discloses a microwave oven ventilation grid, including an oven body and an exhaust pipe installed at the exhaust port of the oven body, the exhaust pipe includes a first pipe, a second pipe is installed at one end of the first pipe, a collecting pipe is installed at the other end of the second pipe, a condenser, a filter, an activated carbon adsorption net and an exhaust fan are installed in the collecting pipe from bottom to top, and the condenser is filled with a refrigerant. The oil in the flue gas is collected through the collecting pipe, and the condenser filled with refrigerant cools the flue gas flowing through, ensuring that more oil in the flue gas is condensed in the collecting pipe for collection and heat exchange recovery, and the exhaust fan is started to accelerate the circulation of air inside the collecting pipe, and the oil in the flue gas is filtered and adsorbed through the filter and the activated carbon adsorption net, thereby improving the emission quality and reducing the pollution to the surrounding environment.

[0004] However, in the above technology, the exhaust ducts are all located outside the oven body, resulting in a larger overall volume of the oven body and a larger occupied space; and an additional exhaust fan needs to be installed in the exhaust duct to provide driving force, resulting in a higher overall cost, and the top of the oven body is heavy, which easily causes an unstable center of gravity, affecting the overall stability and safety of the equipment. Summary of the invention

[0005] In order to effectively solve the above problems, the present application provides a frying and grilling device.

[0006] The present application provides a grilling device, which adopts the following technical solution: A frying and grilling device comprises an upper shell and a lower shell, wherein a pot body assembly is arranged in the lower shell, a hot air circulation assembly and a hot air outlet connected to the interior of the pot body assembly are arranged in the upper shell, a cold air cavity is also arranged in the upper shell, a second fan is arranged in the cold air cavity, and an oil fume treatment module is also included, wherein the air inlet of the second fan is connected to the oil fume treatment module so that the second fan draws the oil fume discharged from the hot air outlet into the oil fume treatment module for treatment.

[0007] Optionally, the oil fume processing module includes a filter component with a smoke extraction port and an oil fume purification component. The filter component is located on one side of the hot air outlet, and the hot air outlet and the smoke extraction port of the filter component are at least partially arranged to correspond to each other, so that the second fan can draw the oil fume discharged from the hot air outlet into the filter component for filtration.

[0008] Optionally, the filter assembly is located above the hot air outlet.

[0009] Optionally, a accommodating chamber connected to the cold air chamber is also provided in the upper shell body, the oil fume purification component is located in the accommodating chamber or the cold air chamber, and one end of the oil fume purification component is connected to the filter component, and the other end is connected to the air inlet of the second fan.

[0010] Optionally, a accommodating chamber connected to the cold air chamber is further provided in the upper shell body, the oil fume purification component is located in the accommodating chamber or the cold air chamber, the filter component is connected to the second fan and the oil fume purification component, and the oil fume treatment module also includes an air guide component so that the oil fume in the filter component is drawn into the oil fume purification component under the action of the second fan.

[0011] Optionally, a mounting cavity is provided in the upper shell, and the filter assembly has a first working state of being folded in the mounting cavity and a second working state of extending out of the mounting cavity.

[0012] Optionally, the filter assembly is in the first working state, and a corresponding guide structure is provided between the hot air outlet and the smoke outlet, so that the hot air outlet and the smoke outlet are at least partially arranged to correspond to each other.

[0013] Optionally, the filter assembly is in a second working state, and the filter assembly is flipped 60°-90° so that the hot air outlet and the smoke outlet of the filter assembly are at least partially arranged to correspond to each other.

[0014] Optionally, the oil fume purification component includes a smoke collecting box and a negative ion generator connected to the smoke collecting box, a smoke outlet pipe is provided between the smoke collecting box and the air inlet of the second air duct, and the other end of the smoke collecting box away from the smoke outlet pipe is connected to the filter component.

[0015] In summary, this application has at least the following beneficial effects: 1. The heating element is heated. The first fan rotates under the drive of the motor to transfer the heat generated by the heating element to the pot assembly to heat the food in the pot assembly. After the food is heated, a large amount of oil smoke will be generated. Since the pot assembly is relatively sealed, the high-temperature air mixed with a large amount of oil smoke is discharged through the hot air outlet. At the same time, the second fan rotates under the drive of the motor to form a negative pressure environment in the cold air chamber, so that the oil smoke discharged from the outlet can be drawn into the oil smoke treatment module for treatment, thereby improving the purification effect of the oil smoke and greatly reducing the pollution of some harmful substances in the oil smoke to the atmosphere and human body.

[0016] In addition, this solution uses a second fan to provide driving force for the oil fume treatment module, and there is no need to install an additional exhaust fan. The structure is simpler, the product size is smaller, the cost is lower, and it is more convenient to use. While ensuring the oil fume removal effect, the weight of the upper shell is reduced, making the overall center of gravity of the frying and grilling equipment more stable, thereby improving safety in use.

[0017] 2. The second fan draws the oil fume discharged from the hot air outlet into the filter component. Since the inside of the filter component is in a normal temperature environment, the gaseous oil in the oil fume is liquefied when it encounters a normal temperature environment with a lower temperature than itself, and condenses into liquid oil and adheres to the filter component. The filtered oil fume reaches the oil fume purification component under the action of the second fan, and the smoke particles in the oil fume are purified and discharged through the oil fume purification component, which can improve the purification effect of the oil fume and reduce the oil and some harmful substances in the oil fume, which can not only ensure the health of the user, but also avoid the discharged oil fume from polluting the surface of the air fryer shell and the kitchen environment.

[0018] 3. The filter component is located above the hot air outlet. Since the temperature of the oil smoke discharged from the hot air outlet is relatively high, its volume expands after being heated, its density decreases, and its weight becomes lighter. Therefore, the oil smoke will flow upward. With the assistance of the second fan, the air intake of the smoke outlet of the filter component can be increased, thereby greatly improving the oil smoke treatment effect.

[0019] 4. The filter assembly has a first working state of being folded in the installation cavity and a second working state of being extended out of the installation cavity. When the filter assembly is in the first working state, it can absorb the oil smoke discharged from the hot air outlet under the action of the second fan, and at the same time, it can be used for storage, which is very convenient to use; when the filter assembly is in the second working state, it can increase the air intake of the smoke outlet, thereby greatly improving the oil smoke treatment effect.

DETAILED DESCRIPTION

[0027] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments are only specific descriptions of the present application, and their purpose is to allow those skilled in the art to better understand the technical solution of the present application, and should not be regarded as limiting the present application.

[0028] In the description of the present application, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0029] Embodiment 1: The present application embodiment discloses a frying and grilling device, such as Figure 1 and Figure 2As shown, it includes an upper shell 111 and a lower shell 121, a pot body assembly 14 is arranged in the lower shell 121, a hot air circulation assembly 13 and a hot air outlet 15 connected to the inside of the pot body assembly 14 are arranged in the upper shell 111, and the hot air circulation assembly 13 includes a heating element 131, a first fan 132 and a motor 133 for driving the first fan 132 to rotate, a cold air chamber 113 is also arranged in the upper shell 111, and a second fan 115 connected to the motor 133 is arranged in the cold air chamber 113; it also includes an oil fume treatment module 2, and the air inlet of the second fan 115 is connected to the oil fume treatment module 2, so that the second fan 115 draws the oil fume discharged from the hot air outlet 15 into the oil fume treatment module 2 for treatment.

[0030] Among them, the upper shell 111 is also provided with a reflective disk 111 and a motor frame 112, the cold air cavity 113 is formed by the reflective disk 111 and the motor frame 112, and a receiving cavity 114 connected to the cold air cavity 113 is provided between the motor frame 112 and the upper shell 111; the motor 133 is located in the receiving cavity 114 and fixedly arranged on the motor frame 112, the heating element 131 and the first fan 132 are located in the reflective disk 111, and the motor shaft of the motor 133 is connected to the first fan 132 and the second fan 115. A cold air inlet is provided on the upper shell 111 to connect the receiving cavity 114 with the outside, so that the cold air from the outside enters the receiving cavity 114 and the cold air cavity 113 through the cold air inlet under the action of the second fan 115, and can cool down the motor 133 and the upper shell 111.

[0031] The heating element 131 is heated, and the first fan 132 rotates under the drive of the motor 133 to conduct the heat generated by the heating element 131 to the pot body assembly 14 to heat the food in the pot body assembly 14. After the food is heated, a large amount of oil smoke will be generated. Since the pot body assembly 14 is relatively sealed, the high-temperature air mixed with a large amount of oil smoke is discharged through the hot air outlet 15. At the same time, the second fan 115 rotates under the drive of the motor 133 to form a negative pressure environment in the cold air chamber 113, so that the oil smoke discharged from the air outlet can be drawn into the oil smoke treatment module 2 for treatment, thereby improving the purification effect of the oil smoke and greatly reducing the pollution of some harmful substances in the oil smoke to the atmosphere and human body.

[0032] In addition, the present solution adopts a second fan 115 to provide driving force for the oil fume treatment module 2, and there is no need to install an additional exhaust fan. The structure is simpler, the product volume is smaller, the cost is lower, and it is more convenient to use. While ensuring the oil fume removal effect, the weight of the upper shell 111 is reduced, making the overall center of gravity of the frying and grilling equipment more stable, thereby improving safety of use.

[0033] It should be noted that the oil fume treatment module 2 includes a filter component 21 with a smoke extraction port 211 and an oil fume purification component 23. The filter component 21 is located on one side of the hot air outlet 15, and the hot air outlet 15 and the smoke extraction port 211 of the filter component 21 are at least partially arranged to correspond to each other, so that the second fan 115 can draw the oil fume discharged from the hot air outlet 15 into the filter component 21 for filtration.

[0034] The second fan 115 draws the oil smoke exhausted from the hot air outlet 15 into the filter component 21. Since the interior of the filter component 21 is in a normal temperature environment, the gaseous oil in the oil smoke is liquefied when encountering a normal temperature environment with a lower temperature than the gaseous oil, and condenses into liquid oil and adheres to the filter component 21. The filtered oil smoke reaches the oil smoke purification component 23 under the action of the second fan 115. The smoke particles in the oil smoke are purified by the oil smoke purification component 23 and then discharged, which can improve the purification effect of the oil smoke and reduce the oil and some harmful substances in the oil smoke, which can not only ensure the health of the user, but also avoid the discharged oil smoke from polluting the surface of the air fryer shell 1 and the kitchen environment.

[0035] Among them, the filter component 21 is located above the hot air outlet 15. Since the temperature of the oil fume discharged from the hot air outlet 15 is relatively high, its volume expands after being heated, its density decreases, and its weight becomes lighter. Therefore, the oil fume will flow upward. With the assistance of the second fan 115, the air intake of the smoke outlet 211 of the filter component 21 can be increased, thereby greatly improving the oil fume treatment effect.

[0036] As an embodiment, the upper housing 111 is further provided with a receiving chamber 114 connected to the cold air chamber 113, the motor 133 is located in the receiving chamber 114, and the oil fume purification component 23 is located in the receiving chamber 114 or the cold air chamber 113, one end of the oil fume purification component 23 is connected to the filter component 21, and the other end is connected to the second fan 115. In this embodiment, the oil fume purification component 23 is located in the receiving chamber 114.

[0037] Among them, a cold air outlet is provided on the upper shell 111 for connecting the cold air chamber 113 with the outside. During the rotation of the second fan 115, the cold air in the cold air chamber 113 flows outward through the cold air outlet, so that the cold air chamber 113 is in a negative pressure state, and the external cold air enters the accommodating chamber 114 and the cold air chamber 113 through the cold air inlet. At the same time, the oil smoke discharged from the hot air outlet 15 enters the filter component 21 through the smoke extraction port 211 for filtration, and the filtered oil smoke enters the oil smoke purification component 23 for treatment, and the treated oil smoke enters the accommodating chamber 114 and the cold air chamber 113 and is discharged through the cold air outlet.

[0038] Furthermore, the oil fume treatment module 2 also includes an air duct 26, one end of which is connected to the oil fume purification component 23, and the other end extends into the cold air chamber 113, so that the oil fume treated by the oil fume purification component 23 can directly enter the cold air chamber 113, which can shorten the discharge path of the treated oil fume and avoid the treated oil fume from affecting the motor 133.

[0039] In this embodiment, the cold air outlet is connected to the hot air outlet 15, and the hot air outlet 15 is located at the rear side of the upper shell 111, and the cold air outlet is located below the hot air outlet 15, so as to prevent the cold air and the treated oil smoke discharged from the cold air outlet from being drawn into the oil smoke treatment module 2 for further treatment. In other embodiments, the cold air outlet can be located on the left or right side of the upper shell 111 to ensure the overall aesthetics.

[0040] It should be noted that the filter assembly 21 includes a mounting frame 212 with a vent 213, the mounting frame 212 is fixedly connected to the upper shell 111, the oil fume purification assembly 23 is connected to the vent 213, the smoke outlet 211 is located on the side of the mounting frame 212 away from the vent 213, and a filter 214 is provided in the mounting frame 212 and between the vent 213 and the smoke outlet 211, so that the oil fume discharged from the hot air outlet 15 enters the mounting frame 212 through the smoke outlet 211 and flows through the filter 214, so that the gaseous oil in the oil fume condenses into liquid oil and adheres to the filter 214, and the filtered oil fume reaches the oil fume purification assembly 23 through the vent 213.

[0041] Among them, combined Figure 3 The mounting frame 212 is located above the hot air outlet 15, and has an inclination angle of 60°-90° with the upper shell 111, and the filter 214 has the same inclination angle as the mounting frame 212, so that the mounting frame 212 is tilted upward from the inside to the outside, so that the hot air outlet 15 and the smoke outlet 211 of the filter assembly 21 are all arranged correspondingly, which can increase the air intake of the smoke outlet 211, thereby greatly improving the fume treatment effect.

[0042] In other embodiments, in combination Figure 4The upper shell 111 is provided with a mounting cavity 16 above the hot air outlet 15, and the mounting frame 212 is folded and arranged in the mounting cavity 16. The smoke extraction port 211 is arranged outward, and can absorb the oil smoke discharged from the hot air outlet 15 under the action of the second fan 115, and can also be used to store the grilling equipment, which is very convenient to use. The hot air outlet 15 and the smoke extraction port 211 are both provided with grills. The grills at the hot air outlet 15 are arranged to be tilted upward from the inside to the outside, and the grills at the smoke extraction port 211 are arranged to be tilted downward from the inside to the outside, so that the oil smoke discharged from the hot air outlet 15 tends to move upward, and the smoke extraction port 211 tends to be sucked downward, which helps to draw the oil smoke discharged from the hot air outlet 15 into the filter assembly 21 under the action of the second fan 115.

[0043] The oil fume purification component 23 includes a smoke collecting box 231 and a negative ion generator 232 connected to the smoke collecting box 231. A smoke outlet pipe 234 is arranged between the smoke collecting box 231 and the air inlet of the second fan 115. The other side of the smoke collecting box 231 away from the smoke outlet pipe 234 is connected to the filter component 21 through the smoke extraction pipe 233. The negative ions generated by the negative ion generator 232 enter the smoke collecting box 231, combine with positively charged particles such as smoke particles in the oil fume, form larger particles, and sink to the bottom of the smoke collecting box 231. The purified oil fume enters the cold air chamber 113 through the smoke outlet pipe 234 and is discharged through the cold air outlet.

[0044] Among them, an oil collecting chamber 215 is provided in the mounting frame 212 and at one end of the filter 214 close to the upper shell 111. The gaseous grease in the oil smoke condenses into liquid grease and adheres to the filter 214. Since the filter 214 is arranged at an angle, the liquid grease adhered to the filter 214 flows downward along the filter 214 into the oil collecting chamber 215.

[0045] The oil fume treatment module 2 also includes an oil collecting box 25, an oil suction pipe 251 is provided between the oil collecting box 25 and the oil collecting chamber 215, and the height of the oil collecting box 25 is lower than the height of the oil collecting chamber 215, or the position of the oil suction pipe 251 in the oil collecting box 25 is lower than the height of the oil collecting chamber 215, so that the grease in the oil collecting chamber 215 flows into the oil collecting box 25 for easy collection and utilization. The oil collecting box 25 is located below the smoke collecting box 231, and the smoke collecting box 231 is provided with an oil leakage hole 252 connected to the oil collecting box 25, which helps the particles settled to the bottom of the smoke collecting box 231 to drip into the oil collecting box 25 through the oil leakage hole 252.

[0046] It should be noted that, combined with Figure 5The oil collecting box 25 is detachably arranged in the upper shell 111. The upper shell 111 is provided with a first opening 281 communicating with the accommodating chamber 114, and a support frame 28 is provided in the accommodating chamber 114 and on the motor 133 frame 112. The support frame 28 has a second opening corresponding to the first opening 281. The oil collecting box 25 extends into the support frame 28 through the first opening 281 and the second opening, and the side wall of the oil collecting box 25 seals the first opening 281 and the second opening, so that the oil collecting box 25 can be taken out of the support frame 28 for cleaning and replacement. A groove or a handle is provided on the outer side of the oil collecting box 25 to facilitate the pulling and drawing of the oil collecting box 25.

[0047] Embodiment 2: The difference between this embodiment and the above embodiment is that: Figure 6 A accommodating chamber 114 connected to the cold air chamber 113 is also provided in the upper shell 111. The oil fume purification component 23 is located in the accommodating chamber 114 or the cold air chamber 113. The filter component 21 is connected to the second fan 115 and the oil fume purification component 23. The oil fume treatment module 2 also includes an air guide structure so that the oil fume in the filter component 21 is drawn into the oil fume purification component 23 under the action of the second fan 115.

[0048] Specifically, the air guide structure includes an air suction pipe 272 and a smoking duct 27 arranged between the oil fume purification component 23 and the filter component 21. An air suction port is arranged at one end of the smoking duct 27 close to the filter component 21. One end of the air suction pipe 272 is connected to the air suction port, and the other end is connected to the air inlet of the second fan 115; the diameter of the air suction port is smaller than the diameter of the smoking duct 27, and the air suction port is located at the bottom of the smoking duct 27. During the rotation of the second fan 115, the cold air in the cold air chamber 113 flows outward through the cold air outlet, so that the cold air chamber 113 is in a negative pressure state, and the external cold air enters the accommodating chamber 114 and the cold air chamber 113 through the cold air inlet, and at the same time, the wind speed at the air intake port is increased and the air pressure is reduced, thereby forming a pressure difference at the air intake port, causing the oil smoke discharged from the hot air outlet 15 to enter the filter assembly 21 for filtration, and further increasing the flow rate of the oil smoke to the filter assembly 21. Since the diameter of the air intake port is smaller than the diameter of the smoking duct 27, most of the filtered oil smoke enters the oil fume purification assembly 23 through the smoking duct and is discharged.

[0049] In order to further improve the purification effect of oil smoke, a baffle 271 is provided in the smoke duct 27 and at the air suction port, and the baffle 271 is located on the side of the air suction port close to the filter assembly 21, effectively preventing the filtered oil smoke from entering the air suction pipe 272.

[0050] Embodiment 3: The difference between this embodiment and the above embodiment is that: the upper shell 111 is provided with a mounting cavity 16, and the filter assembly 21 has a first working state of being folded in the mounting cavity 16 and a second working state of being extended out of the mounting cavity 16. When the filter assembly 21 is in the first working state, the oil smoke discharged from the hot air outlet 15 can be absorbed by the second fan 115, and the oil smoke can also be stored, which is very convenient to use; when the filter assembly 21 is in the second working state, the air intake of the smoke outlet 211 can be increased, thereby greatly improving the oil smoke treatment effect.

[0051] The grilling device also includes an oil smoke detection module, which can be set as an oil smoke sensor, which is set at the hot air outlet 15 and is used to detect the oil smoke concentration at the hot air outlet 15. When the oil smoke concentration is greater than or equal to a preset threshold, the filter component 21 is in the second working state; when the oil smoke concentration is less than the preset threshold, the filter component 21 is in the first working state, so as to switch the first working state and the second working state of the filter component 21 according to the oil smoke concentration. The preset threshold can be set to 45 -60 , which can be set to 50 .

[0052] When the oil fume concentration at the hot air outlet 15 is less than the preset threshold value, the amount of oil fume at the hot air outlet 15 is small, and the oil fume discharged from the hot air outlet 15 can all enter the filter component 21 and the oil fume purification component 23 for treatment under the suction force of the second fan 115, thereby reducing the grease and harmful substances in the oil fume; when the oil fume concentration at the hot air outlet 15 is greater than the preset threshold value, the amount of oil fume at the hot air outlet 15 is large, and extending the filter component 21 from the installation cavity 16 can increase the air intake of the smoke outlet 211, thereby greatly improving the oil fume treatment effect.

[0053] When the filter assembly 21 is connected to the oil fume purification assembly 23, the smoke extraction pipe 233 disposed between the filter assembly 21 and the oil fume purification assembly 23 is configured as a telescopic pipe, and the telescopic pipe is extended when the filter assembly 21 is in the second working state, wherein the telescopic pipe is configured as an aluminum foil telescopic pipe, which can not only meet the effect of switching the filter assembly 21 between the first working state and the second working state, but also has good high temperature resistance to ensure safety in use. In other embodiments, the oil fume treatment module 2 further includes a telescopic pipe, one end of which is connected to the smoke extraction pipe 233, and the other end is connected to the filter assembly 21 or the oil fume purification assembly 23.

[0054] In the case where the filter assembly 21 is connected to the oil fume purification assembly 23 and the air inlet of the second fan 115, the oil fume treatment module 2 further includes a first telescopic tube and a second telescopic tube, one end of the first telescopic tube is connected to the oil fume purification assembly 23, and the other end is connected to the smoking duct 27; the second telescopic tube is arranged in the middle of the suction duct 272, or one end of the second telescopic tube is connected to the air inlet of the second fan 115, and the other end is connected to the suction duct 272; wherein the telescopic tube is arranged as an aluminum foil telescopic tube, so that the first telescopic tube and the second telescopic tube have high temperature resistance, thereby achieving the effect of switching the filter assembly 21 between the first working state and the second working state, and also improving the safety of use. In other embodiments, the smoking duct 27 and the suction duct 272 are both arranged as aluminum foil telescopic tubes.

[0055] The filter assembly 21 is rotatably disposed in the installation cavity 16, and a rotation shaft that rotates with the machine head is disposed on the filter assembly 21, or a rotation shaft that rotates with the filter assembly 21 is disposed on the machine head, and the switching between the first working state and the second working state is realized by the rotation of the filter assembly 21. In other embodiments, the filter assembly 21 can be pulled out and disposed in the installation cavity 16, and the switching between the first working state and the second working state is realized by pulling out the filter assembly 21.

[0056] It should be noted that a partition is arranged between the accommodating cavity 114 and the installation cavity 16, and an opening for the telescopic tube to be inserted is arranged on the partition. While ensuring that the suction component can provide suction, the probability of external cold air entering the accommodating cavity 114 through the gap of the filter component 21 when the filter component 21 is in the second working state is reduced, thereby improving the heating efficiency and heating effect in the pot body component 14.

[0057] The user can judge the oil fume concentration according to the type of food and switch the working state of the filter component 21. For example, grilled meat, fried eggs, fried ribs, grilled fish and other foods with more fat produce a higher oil fume concentration during cooking, so the filter component 21 is adjusted to the second working state; vegetables and other foods with less fat produce a lower oil fume concentration during cooking, so the filter component 21 is adjusted to the first working state.

[0058] In other embodiments, the cooking device also includes a controller and an alarm. The controller is connected to the oil fume detection module and the alarm. When the oil fume concentration at the air outlet is greater than or equal to a preset threshold, the controller controls the alarm to sound an alarm, thereby reminding the user to switch the working state of the filter component 21.

[0059] Embodiment 4: The difference between this embodiment and the above embodiment is that the oil fume treatment module 2 further includes a driving member for driving the filter assembly 21 to rotate, so that the filter assembly 21 switches between the first working state and the second working state. The driving member includes a driving motor, which is arranged in the upper housing 111 and connected to the rotating shaft, so that the filter assembly 21 rotates under the drive of the driving motor.

[0060] The driving motor is connected to the controller. When the oil fume concentration at the hot air outlet 15 is greater than or equal to a preset threshold, the controller controls the driving motor to start, and the driving motor controls the filter component 21 to switch between the first working state and the second working state. The filter component 21 can adjust its state according to the real-time oil fume concentration at the hot air outlet 15, thereby further improving the oil fume treatment effect.

[0061] In other embodiments, when the oil fume concentration at the hot air outlet 15 is greater than or equal to a preset threshold, the controller controls the drive motor to start and at the same time controls the alarm to sound an alarm, which can not only adjust the working state of the filter component 21 in real time, but also remind the user so that the user can understand the cooking progress and improve the user experience.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
