Description

Technical Field

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

[0002] Cooking equipment will produce a lot of oil smoke in the process of cooking food. As a mixed pollutant, oil smoke is an aerosol composed of a very complex mixture 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 cooking equipment has become an urgent problem to be solved in the application of cooking equipment.

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, all the exhaust pipes are located outside the oven body, resulting in a larger overall volume of the oven body, occupying a larger space, making it inconvenient to transport, and requiring users to install it themselves, which is inconvenient to operate; and there is only one working state in this solution, and different treatment methods cannot be selected according to the fume concentration. Summary of the invention

[0007] Optionally, it also includes an oil fume detection module, which is used to detect the oil fume concentration at the air outlet. When the oil fume concentration is greater than or equal to a preset threshold, the filter component is in the second working state; when the oil fume concentration is less than the preset threshold, the filter component is in the first working state.

[0008] Optionally, the oil fume processing module further comprises a telescopic tube disposed between the filter assembly and the air suction assembly, and the telescopic tube is extended when the filter assembly is in the second working state.

[0009] Optionally, the oil fume treatment module further includes a driving member for driving the filter assembly to rotate, so that the filter assembly can be switched between a first working state and a second working state.

[0011] Optionally, the filter assembly is in the second working state, and the filter assembly is flipped 60°-90° so that the air outlet and the smoking port of the filter assembly are at least partially arranged to correspond to each other.

[0012] Optionally, the oil fume purification component includes a smoke collection box and a negative ion generator connected to the smoke collection box, and a smoke extraction pipe is arranged between the smoke collection box and the suction component; a smoke exhaust port connecting the smoke collection box with the outside is arranged on the shell, and the side of the smoke collection box away from the smoke extraction pipe is connected to the smoke exhaust port through the smoke exhaust pipe.

[0014] Optionally, the filter assembly further includes a filter screen and an oil collecting chamber arranged at the bottom of the filter screen, and the oil fume treatment module further includes an oil collecting box, and an oil suction pipe is arranged between the oil collecting box and the oil collecting chamber.

[0015] Optionally, the oil collecting box is located below the smoke collecting box, and the smoke collecting box is provided with an oil leakage hole connected to the oil collecting box.

[0016] In summary, this application has at least the following beneficial effects: 1. The heating element is heated, and the fan blades rotate under the drive of the motor to conduct the heat generated by the heating element to the pot body assembly to heat the food in the pot body assembly. After the food is heated, a large amount of oil smoke will be generated. Since the pot body assembly is relatively sealed, the high-temperature air mixed with a large amount of oil smoke is discharged through the air outlet. At this time, the suction component is started, and the suction component draws the oil smoke discharged from the air outlet into the filter component. The inside of the filter component is in a normal temperature environment. The gaseous grease in the oil smoke will liquefy when it encounters a normal temperature environment with a lower temperature than its temperature, and condense into liquid grease and adhere to the filter component. The filtered oil smoke reaches the oil smoke purification component under the action of the suction component. The smoke particles in the oil smoke are purified and discharged by the oil smoke purification component, which can improve the purification effect of the oil smoke and greatly reduce the pollution of some harmful substances in the oil smoke to the atmosphere and human body.

[0017] The filter assembly has a first working state in which it is folded in the installation cavity and a second working state in which it extends out of the installation cavity. When the filter assembly is in the first working state, it can absorb the oil smoke discharged from the air outlet under the action of the suction assembly, and at the same time it can also be used for storage to reduce the overall volume, 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, which is convenient for improving the oil smoke treatment efficiency, thereby greatly improving the oil smoke treatment effect.

[0018] In addition, the oil fume treatment module in the cooking device is completely or partially located in the shell. Compared with the prior art, the product is smaller in size and more convenient to transport and store.

[0019] 2. The oil fume detection module is used to detect the oil fume concentration at the air outlet. When the oil fume concentration at the air outlet is less than the preset threshold, the amount of oil fume at the air outlet is small, and the oil fume discharged from the air outlet can all enter the filter component and the oil fume purification component for treatment under the suction of the suction component, thereby reducing the grease and harmful substances in the oil fume; when the oil fume concentration at the air outlet is greater than or equal to the preset threshold, the amount of oil fume at the air outlet is large, and extending the filter component from the installation cavity can increase the air intake of the smoke outlet, thereby greatly improving the oil fume treatment effect.

[0020] 3. The oil fume treatment module also includes a telescopic tube arranged between the filter assembly and the suction assembly. When the filter assembly is in the second working state, the telescopic tube is extended, which can not only meet the effect of switching the filter assembly between the first working state and the second working state, but also has good high temperature resistance to ensure safe use.

[0021] 4. The oil fume treatment module also includes a driving member for driving the filter component to rotate so that the filter component can switch between a first working state and a second working state. When the oil fume concentration at the air outlet is greater than or equal to a preset threshold, the driving member controls the filter component to switch between the first working state and the second working state. The filter component can adjust its state according to the real-time oil fume concentration at the air outlet to further improve the oil fume treatment effect.

[0022] 5. The oil fume purification component includes a smoke collecting box and a negative ion generator connected to the smoke collecting box. A smoke extraction pipe is provided between the smoke collecting box and the air suction component. A smoke exhaust port is provided on the machine head to connect the smoke collecting box with the outside world. The side of the smoke collecting box away from the smoke extraction pipe is connected to the smoke exhaust port through the smoke exhaust pipe. The negative ions generated by the negative ion generator enter the smoke collecting box, 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. The purified oil fume is discharged through the smoke exhaust pipe and the smoke exhaust port. The smoke extraction pipe and the smoke exhaust pipe are located on both sides of the smoke collecting box to ensure that the oil fume entering the smoke collecting box fully reacts with the negative ions, which can further improve the oil fume purification effect.

[0028] 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.

[0029] 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.

[0030] The present application embodiment discloses a cooking device for frying and grilling, such as Figure 1 and Figure 2 As shown, it includes a shell 1, a pot body assembly 14 and a hot air circulation assembly 13 arranged in the shell 1, wherein 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, an air outlet 15 connected to the inside of the pot body assembly 14 is provided on the shell 1, and also includes an oil fume treatment module 2, the oil fume treatment module 2 includes a filter assembly 21 with a smoke extraction port 211, an air suction assembly 22 and an oil fume purification assembly 23, the air suction assembly 22 and the oil fume purification assembly 23 are arranged in the shell 1, and an installation cavity 16 is arranged in the shell 1 and above the air outlet 15, the filter assembly 21 has a first working state folded in the installation cavity 16 and a second working state extending out of the installation cavity 16, the air outlet 15 is at least partially corresponding to the smoke extraction port 211 of the filter assembly 21, and the air suction assembly 22 draws the oil fume discharged from the air outlet 15 into the filter assembly 21 for filtration.

[0031] The heating element 131 is heated, and the fan blade 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, heating the food in the pot body assembly 14, and the oil smoke generated during the heating process is discharged through the air outlet 15. At this time, the suction component 22 is started, and the suction component 22 draws the oil smoke discharged from the air outlet 15 into the filter component 21. The gaseous grease in the oil smoke is liquefied when it contacts the colder filter component 21, condensed into liquid grease and adheres to the filter component 21. The filtered oil smoke reaches the oil smoke purification component 23 under the action of the suction component 22. The smoke particles in the oil smoke are purified by the oil smoke purification component 23 and discharged, which can improve the purification effect of the oil smoke and greatly reduce the pollution of some harmful substances in the oil smoke to the atmosphere and human body.

[0032] In addition, the filter component 21 has a first working state in which it is folded in the installation cavity 16 and a second working state in which it extends out of the installation cavity 16. When the filter component 21 is in the first working state, it can absorb the oil smoke discharged from the air outlet 15 under the action of the suction component 22, and at the same time it can be used for storage, which is very convenient to use; when the filter component 21 is in the second working state, it can increase the air intake of the smoke outlet 211, thereby greatly improving the oil fume treatment effect.

[0033] Taking the air fryer as an example, the shell 1 includes a base 12 and a head 11 covered on the base 12. The head 11 and the base 12 can be fixedly connected or rotatably connected. The pot body assembly 14 is arranged in the base 12, and the hot air circulation assembly 13 is arranged in the head 11. A reflection plate 111 and a motor frame 112 are also arranged in the head 11. A cold air cavity 113 is arranged between the reflection plate 111 and the motor frame 112. An accommodating cavity 114 connected to the cold air cavity 113 is arranged between the motor frame 112 and the head 11. The motor 133 is located in the accommodating cavity 114 and is fixedly arranged on the motor frame 112. The heating element 131 and the fan blade 132 are arranged in the reflection plate 111. The motor 133 shaft of the motor 133 passes through the motor frame 112 and the reflection plate 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 chamber 113, and a cold air inlet is provided on the machine head 11 to connect the accommodating chamber 114 with the outside world, so that the cold air from the outside can enter the accommodating chamber 114 and the cold air chamber 113 through the cold air inlet under the action of the cold air blade 115, and can cool down the motor 133 and the machine head 11.

[0034] In other embodiments, the hot air circulation component 13 is disposed on one side of the pot body component 14 , and a first space is disposed between the pot body component 14 and the rear side of the shell 1 , and the reflective plate 111 and the motor frame 112 are both disposed in the first space.

[0035] Among them, the air suction component 22 and the oil fume purification component 23 are also arranged in the accommodating cavity 114, without occupying additional space. At the same time, the air suction component 22 and the oil fume purification component 23 can be cooled to increase their service life.

[0036] It is understandable that since the concentration of oil smoke emitted by the air fryer is relatively low, usually below 0.1 mg, although the oil smoke concentration below the industry standard will not cause serious damage to human health like high-concentration oil smoke, long-term exposure to an environment containing oil smoke will still have an adverse effect on health. Therefore, the oil smoke emitted from the air outlet 15 is processed by the oil smoke processing module 2 to reduce the grease and harmful substances in the oil smoke, which can not only ensure the health of the user, but also prevent the emitted oil smoke from polluting the surface of the air fryer shell 1 and the kitchen environment.

[0037] The cooking device also includes an oil smoke detection module, which can be set as an oil smoke sensor, which is set at the air outlet 15 and is used to detect the oil smoke concentration at the 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 .

[0038] When the oil fume concentration at the air outlet 15 is less than a preset threshold value, the amount of oil fume at the air outlet 15 is small, and the oil fume discharged from the 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 suction component 22, thereby 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 value, the amount of oil fume at the 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.

[0039] In this embodiment, the filter assembly 21 is connected to the air inlet end of the air suction assembly 22, and the oil fume purification assembly 23 is connected to the air outlet end of the air suction assembly 22, so that the oil fume discharged from the air outlet 15 can be drawn into the filter assembly 21 and the oil fume purification assembly 23. In other embodiments, one end of the oil fume purification assembly 23 is connected to the filter assembly 21, and the other end is connected to the air suction assembly 22, so as to prevent untreated oil fume from flowing through the air suction assembly 22 and causing pollution to the inside of the air suction assembly 22.

[0040] Combination Figure 3 The oil fume treatment module 2 also includes a telescopic tube 24 arranged between the filter component 21 and the suction component 22. When the filter component 21 is in the second working state, the telescopic tube 24 is extended, wherein the telescopic tube 24 is set as an aluminum foil telescopic tube 24, which can not only meet the effect of switching the filter component 21 between the first working state and the second working state, but also has good high temperature resistance to ensure safe use.

[0041] The filter assembly 21 is rotatably disposed in the installation cavity 16, and a rotation shaft that rotates with the head 11 is disposed on the filter assembly 21, or a rotation shaft that rotates with the filter assembly 21 is disposed on the head 11, and the switching between the first working state and the second working state is achieved 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 achieved by pulling out the filter assembly 21.

[0042] Specifically, the filter assembly 21 includes a mounting frame 212 having a vent 213, the mounting frame 212 is rotatably connected to the machine head 11 via a rotating shaft, the suction assembly 22 is connected to the vent 213 via a telescopic tube 24, 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 smoke discharged from the 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 smoke condenses into liquid oil and adheres to the filter 214, and the filtered oil smoke reaches the suction assembly 22 through the vent 213 and the telescopic tube 24.

[0043] It should be noted that a partition is arranged between the accommodating cavity 114 and the installation cavity 16, and an opening is arranged on the partition for the telescopic tube 24 to extend therein. While ensuring that the suction component 22 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.

[0044] The user can judge the oil fume concentration according to the type of food and switch the working state of the filter component 21 by himself. For example, the oil fume concentration generated by foods with more fat, such as barbecue, fried eggs, fried ribs, and grilled fish, is relatively large during the cooking process, and the filter component 21 is adjusted to the second working state; the oil fume concentration generated by foods with less fat, such as vegetables, is relatively small during the cooking process, and the filter component 21 is adjusted to the first working state. In other embodiments, the cooking device also includes a controller and an alarm, and the controller is connected to the oil fume detection module and the alarm. When the oil fume concentration at the air outlet 15 is greater than or equal to the preset threshold, the controller controls the alarm to sound an alarm, and at this time reminds the user to switch the working state of the filter component 21.

[0045] The filter assembly 21 is in the first working state, and a corresponding guide structure is provided between the air outlet 15 and the smoke outlet 211, so that the air outlet 15 and the smoke outlet 211 are at least partially arranged correspondingly. Specifically, grilles are provided at both the air outlet 15 and the smoke outlet 211, and the grilles at the air outlet 15 are arranged upwardly inclined from the inside to the outside, and the grilles at the smoke outlet 211 are arranged downwardly inclined from the inside to the outside, so that the oil smoke discharged from the air outlet 15 tends to move upward, and the smoke outlet 211 tends to be sucked downward, which helps to draw the oil smoke discharged from the air outlet 15 into the filter assembly 21 under the action of the suction assembly 22.

[0046] The filter assembly 21 is in the second working state, the filter assembly 21 is flipped 60°-90° and is located above the air outlet 15, that is, the mounting frame 212 is tilted upward from the inside to the outside, so that the air outlet 15 and the smoke outlet 211 of the filter assembly 21 are at least partially corresponding to each other, which can increase the air intake of the smoke outlet 211, thereby greatly improving the oil fume treatment effect.

[0047] In addition, the air suction component 22 can be set as a fan, the air inlet end of the fan is connected to the filter component 21, and the air outlet end is connected to the oil fume purification component 23, which can achieve oil fume purification while having a simple structure and easy use.

[0048] 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 extraction pipe 233 is arranged between the smoke collecting box 231 and the air suction component 22. A smoke exhaust port for connecting the smoke collecting box 231 with the outside is arranged on the machine head 11. The side of the smoke collecting box 231 away from the smoke extraction pipe 233 is connected to the smoke exhaust port through the smoke exhaust pipe 234. 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 settle down to the bottom of the smoke collecting box 231. The purified oil fume is discharged through the smoke exhaust pipe 234 and the smoke exhaust port. In addition, the smoke extraction pipe 233 and the smoke exhaust pipe 234 are located on both sides of the smoke collecting box 231, so as to ensure that the oil fume entering the smoke collecting box 231 fully reacts with the negative ions, which can further improve the oil fume purification effect.

[0049] The smoke exhaust port is connected to the air outlet 15, and the air outlet 15 is located at the rear side of the machine head 11. The smoke exhaust port is located at the lower part of the air outlet 15, which effectively prevents the oil smoke discharged from the smoke exhaust port from being drawn into the oil smoke treatment module 2 for further treatment, thereby improving the oil smoke purification efficiency. In other embodiments, the smoke exhaust port is located on one side of the air outlet 15, which can be set on the left or right side of the machine head 11, which can ensure the overall aesthetics.

[0050] It should be noted that the filter assembly 21 also includes an oil collecting chamber 215 disposed at the bottom of the filter 214. The gaseous grease in the oil smoke condenses into liquid grease and adheres to the filter 214. The liquid grease adhered to the filter 214 flows downward along the filter 214 into the oil collecting chamber 215. The oil smoke treatment module 2 also includes an oil collecting box 25. An oil suction pipe 251 is disposed between the oil collecting box 25 and the oil collecting chamber 215. When the filter assembly 21 is in the first working state, the grease in the oil collecting chamber 215 flows into the oil collecting box 25 through the oil suction pipe 251, which is conducive to subsequent recovery and utilization.

[0051] 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 collecting box 25 where the oil suction pipe 251 is located 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.

[0052] Combination Figure 4 The oil collecting box 25 is detachably arranged in the machine head 11. The machine head 11 is provided with a first opening 261 communicating with the accommodating chamber 114, and a support frame 26 is provided in the accommodating chamber 114 and on the motor 133 frame 112. The support frame 26 has a second opening corresponding to the first opening 261. The oil collecting box 25 extends into the support frame 26 through the first opening 261 and the second opening, and the side wall of the oil collecting box 25 seals the first opening 261 and the second opening, so that the oil collecting box 25 can be taken out of the support frame 26 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.

[0053] Embodiment 2: 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 1 and connected to the rotating shaft, so that the filter assembly 21 rotates under the drive of the driving motor.

[0054] The driving motor is connected to the controller. When the oil fume concentration at the 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 air outlet 15, thereby further improving the oil fume treatment effect.

[0055] In other embodiments, when the oil fume concentration at the 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's experience.

[0056] 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.
