Description

Technical Field

[0001] This application relates to the technical field of kitchen equipment, and in particular to a grilling device with a function of removing oil fumes. Background Technology

[0002] Grilling and frying equipment generates a large amount of oil fumes during the grilling and frying process. Oil fumes, as a mixed pollutant, are a very complex aerosol composed of gas, solid, and liquid phases. Their composition changes with the type of food and cooking conditions. The intermediate or final products generated during the reaction process can also undergo secondary reactions due to their interactions, which can pollute the kitchen environment and even affect the health of users. Therefore, how to deal with the oil fumes generated during the operation of smart grilling and frying rice cookers has become an urgent problem to be solved in the application of smart rice cookers.

[0003] A patent with publication number CN220417389U discloses a ventilation grid for a microwave oven, 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 installed at one end of the first pipe, and a collection pipe installed at the other end of the second pipe. Inside the collection pipe, from bottom to top, are a condenser pipe, a filter screen, an activated carbon adsorption screen, and an exhaust fan. The condenser pipe is filled with a refrigerant. The collection pipe collects oil from the flue gas, and the condenser pipe, filled with refrigerant, cools the flowing flue gas, ensuring that more oil in the flue gas condenses in the collection pipe for collection and heat exchange recovery. The exhaust fan is activated to accelerate air circulation inside the collection pipe, and the filter screen and activated carbon adsorption screen filter and adsorb oil from the flue gas, improving emission quality and reducing pollution to the surrounding environment.

[0004] However, in the above technologies, all the exhaust pipes are located outside the oven body, resulting in a large overall size of the oven body, occupying a lot of space, making transportation inconvenient, requiring users to install it themselves, and making operation inconvenient; in addition, this solution only has one location, and cannot select different treatment methods according to the concentration of oil fumes. Utility Model Content

[0005] To effectively solve the above problems, this application provides a grilling device with oil fume removal function.

[0006] This application provides a grilling device with oil fume removal function, which adopts the following technical solution:

[0007] A grilling device with oil fume removal function includes an upper shell and a lower shell. A pot assembly is disposed inside the lower shell, and a hot air circulation assembly and an air outlet communicating with the inside of the pot assembly are disposed inside the upper shell. The device also includes an oil fume treatment module and an installation cavity disposed inside the upper shell. The oil fume treatment module includes a filter assembly, a suction assembly and an oil fume purification assembly. The filter assembly has a first position folded inside the installation cavity and a second position extending out of the installation cavity.

[0008] By adopting the above technical solution, the heat generated by the hot air circulation component enters the pot assembly to heat the food inside. The heated food produces a large amount of oily fumes. Since the pot assembly is relatively sealed, the hot air mixed with a large amount of oily fumes is discharged through the vent. At this time, the suction component is activated, drawing the oily fumes discharged from the vent into the filter assembly. The filter assembly is in a normal temperature environment. When the gaseous grease in the oily fumes encounters the cooler environment, it liquefies and condenses into liquid grease, which adheres to the filter assembly. The filtered oily fumes, under the action of the suction component, reach the oil fume purification component. The oil fume purification component purifies the smoke particles in the oily fumes before discharging them, thus improving the purification effect and significantly reducing the pollution of the atmosphere and human body by some harmful substances in the oily fumes.

[0009] The filter assembly has a first position where it is folded inside the mounting cavity and a second position where it extends out of the mounting cavity. When the filter assembly is in the first position, it can draw in the fumes discharged from the air outlet under the action of the suction assembly. It also helps to store the fumes, reducing the overall volume and making it very convenient to use. When the filter assembly is in the second position, it can increase the air intake of the smoke extraction port, which can improve the efficiency of fume treatment and thus greatly enhance the fume treatment effect.

[0010] In addition, the fume treatment module in this cooking device is entirely or partially housed within the casing, making the product smaller and easier to transport and store compared to existing technologies.

[0011] Optionally, the fume treatment module further includes a telescopic pipe disposed between the filter assembly and the suction assembly.

[0012] By adopting the above technical solution, the telescopic tube extends when the filter assembly is in the second position, which not only satisfies the effect of switching the filter assembly between the first and second positions, but also has good high temperature resistance and ensures safe use.

[0013] Optionally, the filter assembly is rotatably connected to the upper housing.

[0014] By adopting the above technical solution, it is helpful for the filter component to switch between the first position and the second position.

[0015] Optionally, the fume purification component includes a fume collection box and a negative ion generator connected to the fume collection box. A fume extraction pipe is provided between the fume collection box and the suction component. The upper housing is provided with a fume exhaust port that connects the fume collection box to the outside. The side of the fume collection box away from the fume extraction pipe is connected to the fume exhaust port through the fume exhaust pipe.

[0016] Optionally, the smoke exhaust port is connected to the air outlet and is located at the lower part of the air outlet; or, the smoke exhaust port is located on one side of the air outlet.

[0017] Optionally, the filter assembly further includes a mounting bracket, a filter screen disposed within the mounting bracket, and an oil collection chamber disposed within the mounting bracket and at the bottom of the filter screen.

[0018] Optionally, the fume treatment module further includes an oil collection box, which is connected to the oil collection chamber via an oil suction pipe.

[0019] Optionally, the smoke collection box is located above the oil collection box, and the smoke collection box is provided with an oil leakage hole communicating with the oil collection box. Attached Figure Description

[0025] The present application will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely specific illustrations of the present application, and their purpose is to enable those skilled in the art to better understand the technical solutions of the present application, and should not be regarded as limitations on the present application.

[0026] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0027] This application discloses a cooking device for grilling and frying, such as... Figure 1 and Figure 2 As shown, the device includes an upper shell 11 and a lower shell 12. A pot assembly 14 is disposed inside the lower shell 12. A hot air circulation assembly 13 and an air outlet 15 communicating with the interior of the pot assembly 14 are disposed inside the upper shell 11. The hot air circulation assembly 13 includes a heating element 131, a fan blade 132 and a motor 133 for driving the fan blade 132 to rotate. The device also includes an oil fume treatment module 2 and an installation cavity 16 disposed inside the upper shell 11. The oil fume treatment module 2 includes a filter assembly 21, a suction assembly 22 and an oil fume purification assembly 23. Both the suction assembly 22 and the oil fume purification assembly 23 are located inside the upper shell 11. The filter assembly 21 has a first position folded into the installation cavity 16 and a second position extending out of the installation cavity 16.

[0028] The heat generated by the hot air circulation component 13 enters the pot body component 14 to heat the food inside. The heated food produces a large amount of oil fumes. Since the pot body component 14 is relatively sealed, the high-temperature air mixed with a large amount of oil fumes is discharged through the air outlet 15. At this time, the suction component 22 is activated, drawing the oil fumes discharged from the air outlet 15 into the filter component 21. The filter component 21 is in a normal temperature environment. When the gaseous grease in the oil fumes encounters a cooler environment, it liquefies and condenses into liquid grease, which adheres to the filter component 21. The filtered oil fumes, under the action of the suction component 22, reach the oil fume purification component 23. The oil fume purification component 23 purifies the smoke particles in the oil fumes before discharging them, thus improving the purification effect and significantly reducing the pollution of the atmosphere and human body by some harmful substances in the oil fumes.

[0029] The filter assembly 21 has a first position where it is folded inside the mounting cavity 16 and a second position where it extends out of the mounting cavity 16. When the filter assembly 21 is in the first position, it can absorb the oil fumes discharged from the air outlet 15 under the action of the suction assembly 22. At the same time, it can also be stored to reduce the overall volume and is very convenient to use. When the filter assembly 21 is in the second position, it can increase the air intake of the smoke extraction port 211, which can improve the oil fume treatment efficiency and thus greatly improve the oil fume treatment effect.

[0030] Taking an air fryer as an example, the upper shell 11 and the lower shell 12 can be fixedly connected or rotatably connected. The upper shell 11 is also provided with a reflector 111 and a motor frame 112. A cold air chamber 113 is provided between the reflector 111 and the motor frame 112. A receiving cavity 114 communicating with the cold air chamber 113 is provided between the motor frame 112 and the upper shell 11. The motor 133 is located in the receiving cavity 114 and is fixedly installed on the motor frame 112. The heating element 131 and the fan blade 132 are provided in the reflector 111. The motor 133 shaft of the motor 133 passes through the motor frame 112 and the reflector 111 and is connected to the fan blade 132. In addition, a cold air blade 115 connected to the motor 133 is provided in the cold air cavity 113, and a cold air inlet is provided on the upper housing 11 to connect the receiving cavity 114 with the outside world, so that the cold air from the outside world enters the receiving cavity 114 and the cold air cavity 113 through the cold air inlet under the action of the cold air blade 115, which can cool down the motor 133 and the upper housing 11.

[0031] The suction component 22 and the fume purification component 23 are also located in the receiving cavity 114, which does not require additional space. At the same time, they can cool down the suction component 22 and the fume purification component 23, thus improving their service life.

[0032] Understandably, because air fryers emit relatively low concentrations of cooking fumes, typically below 0.1mg, this concentration, while lower than industry standards, will not cause the same severe health damage as high-concentration fumes. However, long-term exposure to an environment containing cooking fumes can still have adverse health effects. Therefore, the fume treatment module 2 treats the fumes emitted from the air outlet 15, reducing the amount of grease and harmful substances in the fumes. This ensures the user's health while preventing the emitted fumes from polluting the surface of the air fryer's upper shell 11 and the kitchen environment.

[0033] The cooking equipment also includes an oil fume detection module, which can be configured as an oil fume sensor located at the air outlet 15. This sensor detects the oil fume concentration at the air outlet 15. When the oil fume concentration is greater than or equal to a preset threshold, the filter component 21 is in the second position; when the oil fume concentration is less than the preset threshold, the filter component 21 is in the first position, allowing the system to switch between the first and second positions of the filter component 21 based on the oil fume concentration. The preset threshold can be set to 45. -60 Specifically, it can be set to 50. .

[0034] When the oil fume concentration at the air outlet 15 is less than the preset threshold, the amount of oil fume at the air outlet 15 is small. Under the suction of the suction component 22, all the oil fume discharged from the air outlet 15 can enter the filter component 21 and the oil fume purification component 23 for treatment, reducing the grease and harmful substances in the oil fume. When the oil fume concentration at the air outlet 15 is greater than or equal to the preset threshold, the amount of oil fume at the air outlet 15 is large. Extending the filter component 21 out of the mounting cavity 16 can increase the air intake of the smoke extraction port 211, thereby greatly improving the oil fume treatment effect.

[0035] In this embodiment, the filter assembly 21 is connected to the air inlet of the suction assembly 22, and the fume purification assembly 23 is connected to the air outlet of the suction assembly 22, which can draw the fumes discharged from the air outlet 15 into the filter assembly 21 and the fume purification assembly 23. In other embodiments, one end of the fume purification assembly 23 is connected to the filter assembly 21, and the other end is connected to the suction assembly 22, to prevent untreated fumes from flowing through the suction assembly 22 and causing pollution inside the suction assembly 22.

[0036] Combination Figure 3 The fume treatment module 2 also includes a telescopic tube 24 disposed between the filter assembly 21 and the suction assembly 22. When the filter assembly 21 is in the second position, the telescopic tube 24 extends. The telescopic tube 24 is set as an aluminum foil telescopic tube 24, which can not only meet the effect of the filter assembly 21 switching between the first position and the second position, but also has good high temperature resistance and ensures safe use.

[0037] In this embodiment, the filter assembly 21 is rotatably disposed within the mounting cavity 16. The filter assembly 21 is provided with a rotating shaft that rotates with the upper housing 11, or the upper housing 11 is provided with a rotating shaft that rotates with the filter assembly 21. The rotation of the filter assembly 21 enables switching between a first position and a second position. In other embodiments, the filter assembly 21 is retractable within the mounting cavity 16, and the retraction of the filter assembly 21 enables switching between the first and second positions.

[0038] Specifically, the filter assembly 21 includes a mounting bracket 212 with a vent 213. The mounting bracket 212 is rotatably connected to the upper housing 11 via a rotating shaft. The suction assembly 22 is connected to the vent 213 via a telescopic tube 24. The smoke extraction port 211 is located on the side of the mounting bracket 212 away from the vent 213. A filter screen 214 is provided inside the mounting bracket 212 and between the vent 213 and the smoke extraction port 211, so that the fumes discharged from the air outlet 15 enter the mounting bracket 212 through the smoke extraction port 211 and flow through the filter screen 214, causing the gaseous grease in the fumes to condense into liquid grease and adhere to the filter screen 214. The filtered fumes reach the suction assembly 22 through the vent 213 and the telescopic tube 24.

[0039] It should be noted that a partition is provided between the receiving cavity 114 and the mounting cavity 16. The partition has an opening for the telescopic tube 24 to extend into. While ensuring that the suction assembly 22 can provide suction, it reduces the probability that cold air from the outside will enter the receiving cavity 114 through the gap in the filter assembly 21 when the filter assembly 21 is in the second position, thereby improving the heating efficiency and heating effect inside the pot assembly 14.

[0040] Users can determine the concentration of cooking fumes based on the type of food and adjust the position of the filter component 21 accordingly. For example, foods with high oil content, such as grilled meat, fried eggs, fried ribs, and grilled fish, produce a higher concentration of cooking fumes, so the filter component 21 is adjusted to the second position; foods with low oil content, such as vegetables, produce a lower concentration of cooking fumes, so the filter component 21 is adjusted to the first position. In other embodiments, the cooking device also includes a controller and an alarm. The controller is connected to the fume detection module and the alarm. When the fume concentration at the air outlet 15 is greater than or equal to a preset threshold, the controller activates the alarm, prompting the user to switch the position of the filter component 21.

[0041] The filter assembly 21 is in the first position, and a corresponding guide structure is provided between the air outlet 15 and the smoke extraction port 211 so that the air outlet 15 and the smoke extraction port 211 are at least partially corresponding. Specifically, both the air outlet 15 and the smoke extraction port 211 are provided with grilles. The grille at the air outlet 15 is inclined upward from the inside to the outside, and the grille at the smoke extraction port 211 is inclined downward from the inside to the outside. This causes the oil fumes discharged from the air outlet 15 to move upward, and the smoke extraction port 211 to have a downward suction tendency. This helps to draw the oil fumes discharged from the air outlet 15 into the filter assembly 21 under the action of the suction assembly 22.

[0042] The filter assembly 21 is in the second position. The filter assembly 21 is rotated 60°-90° and located above the air outlet 15. That is, the mounting bracket 212 is set upward from the inside to the outside, so that the air outlet 15 and the smoke extraction port 211 of the filter assembly 21 are at least partially corresponding. This can increase the air intake of the smoke extraction port 211, thereby greatly improving the oil fume treatment effect.

[0043] In addition, the suction component 22 can be configured as a fan, with its air inlet end connected to the filter component 21 and its air outlet end connected to the fume purification component 23. This allows for fume purification while maintaining a simple structure and ease of use.

[0044] The fume purification component 23 includes a fume collection box 231 and a negative ion generator 232 connected to the fume collection box 231. A fume extraction pipe 233 is provided between the fume collection box 231 and the suction component 22. An exhaust port is provided on the upper housing 11 to connect the fume collection box 231 to the outside. The side of the fume collection box 231 away from the fume extraction pipe 233 is connected to the exhaust port via an exhaust pipe 234. Negative ions generated by the negative ion generator 232 enter the fume collection box 231 and combine with positively charged particles such as smoke particles in the fume, forming larger particles that sink to the bottom of the fume collection box 231. The purified fume is discharged through the exhaust pipe 234 and the exhaust port. Furthermore, the fume extraction pipe 233 and the exhaust pipe 234 are located on both sides of the fume collection box 231, ensuring that the fume entering the fume collection box 231 reacts fully with the negative ions, further improving the fume purification effect.

[0045] The exhaust vent is connected to the air outlet 15, and the air outlet 15 is located on the rear side of the upper housing 11. The exhaust vent is located below the air outlet 15, effectively preventing the oil fumes discharged from the exhaust vent from being drawn into the oil fume treatment module 2 for further treatment, thereby improving the oil fume purification efficiency. In other embodiments, the exhaust vent is located on one side of the air outlet 15, which can be set on the left or right side of the upper housing 11 to ensure the overall aesthetics.

[0046] It should be noted that the filter assembly 21 also includes an oil collection chamber 215 located at the bottom of the filter screen 214. Gaseous grease in the oil fumes condenses into liquid grease and adheres to the filter screen 214. The liquid grease adhering to the filter screen 214 flows downwards along the filter screen 214 into the oil collection chamber 215. The oil fume treatment module 2 also includes an oil collection box 25. An oil suction pipe 251 is provided between the oil collection box 25 and the oil collection chamber 215. When the filter assembly 21 is in the first position, the grease in the oil collection chamber 215 flows into the oil collection box 25 through the oil suction pipe 251, which is beneficial for subsequent recycling and utilization.

[0047] The oil collection box 25 is positioned at a height lower than the oil collection chamber 215, or the oil suction pipe 251 is positioned at a height lower than the oil collection chamber 215, so that the grease in the oil collection chamber 215 flows into the oil collection box 25 for easy collection and utilization. The oil collection box 25 is located below the cigarette collection box 231, and the cigarette collection box 231 has an oil drain hole 252 communicating with the oil collection box 25, which helps particles settling to the bottom of the cigarette collection box 231 drip into the oil collection box 25 through the oil drain hole 252.

[0048] Combination Figure 4 The oil collection box 25 is detachably installed inside the upper housing 11. The upper housing 11 has a first opening 261 communicating with the receiving cavity 114. A support frame 26 is installed inside the receiving cavity 114 and on the motor frame 112. The support frame 26 has a second opening corresponding to the first opening 261. The oil collection box 25 extends into the support frame 26 through the first opening 261 and the second opening, and the sidewalls of the oil collection box 25 seal the first opening 261 and the second opening, allowing the oil collection box 25 to be removed from the support frame 26 for cleaning and replacement. The outer side of the oil collection box 25 is provided with a groove or handle for easy pulling out.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
