Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese application with application number 202410287106.8 filed on March 13, 2024 and application name “Cooking appliance control method and cooking appliance”, and the claimed application will be incorporated into this application by reference. Technical Field

[0003] The embodiments of the present application relate to the technical field of cooking appliances, and more particularly to a cooking appliance control method and an air fryer. Background Art

[0004] An air fryer is a machine that uses air to "fry". It mainly uses air to replace the hot oil in the frying pan to cook the food. At the same time, the hot air blows away the moisture on the surface of the food, making the ingredients achieve an effect similar to that of frying.

[0005] Because air fryers use hot air to bake, moisture evaporates from the surface of food. In existing air fryers, this moisture is expelled through the exhaust port along with the air under the action of the fan, making the surface of the food increasingly dry. However, with the increasing diversification of cooking needs, if users need to retain a certain amount of moisture on the surface of the cooked food, existing air fryers cannot achieve this.

[0006] To deal with this situation, existing air fryers usually need to add a water supply box at the bottom of the baking tray, or install a water pump in the air fryer to continuously spray water on the surface of the food during the cooking process to prevent the surface of the food from being too dry.

[0007] However, adding a water replenishing box requires users to add water every time they cook, which is inconvenient; installing a water pump also requires regular water addition, which also increases costs. Summary of the Invention

[0033] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 , Figure 1 A partial cross-sectional view of an air fryer provided in one embodiment of the present application is shown. The air fryer 100 includes a cavity 110, an exhaust duct 120, and a regulating device 130. The exhaust duct 120 is connected to the cavity 110 at one end and to the outside at the other end. The regulating device 130 is used to control the change in the cross-sectional area of ​​the exhaust duct 120.

[0035] like Figure 1 As shown, the regulating device 130 may include a shielding member 131 and a driving member 132 connected to the shielding member. In the embodiment of the present application, there is at least one shielding member 131. The shape of the shielding member 131 may include, but is not limited to, a fan-shaped or rectangular shape. The coverage of the shielding member 131 should include the opening range of the exhaust passage. That is, the size of the shielding member 131 is larger than the opening range of the exhaust passage 120.

[0036] The shielding member 131 is disposed in the exhaust passage 120 , and the driving member 132 is used to drive the shielding member 131 to move, so that the cross-sectional area of ​​the exhaust duct 120 changes.

[0037] like Figure 1 As shown, when the driving member 132 drives the shielding member 131 to move above the exhaust passage 120 , the shielding member 131 does not block the exhaust passage 120 at all. At this time, the cross-sectional area of ​​the exhaust passage 120 is the largest.

[0038] like Figure 2 As shown, when the driving member 132 drives the shielding member 131 to move to abut against the exhaust channel 120, the cross-sectional area of ​​the exhaust channel 120 is the smallest. In some embodiments, no air holes are provided on the shielding member 131, the minimum cross-sectional area of ​​the exhaust channel 120 is 0, the cavity 110 is not connected to the outside world, and the cavity 110 is in a closed state. In other embodiments, as Figure 2 As shown, a vent hole 1311 is provided on the shielding member 131 , the minimum cross-sectional area of ​​the exhaust channel 120 is equal to the cross-sectional area of ​​the vent hole 1311 , the cavity 110 is connected to the outside, and the cavity 110 is not in a closed state.

[0039] In some embodiments, see Figure 2 The shielding member 131 may be a baffle 131A, and a vent hole 1311 may be formed through the baffle 131A. The cross-sectional area of ​​the vent hole 1311 is smaller than the maximum cross-sectional area of ​​the exhaust channel 120. When the baffle 131A is controlled to move by the driving member, the exhaust channel 120 may change between the minimum and maximum values ​​of its cross-sectional area.

[0040] In some embodiments, as Figure 2As shown, the driving member 132 may be a solenoid valve 132A, and the shielding member 131 may be a baffle 131A provided at the exhaust passage 120, with the baffle 131A abutting against the exhaust passage 120 on the side close to the exhaust passage 120. The valve body of the solenoid valve 132A is fixedly connected to the baffle 131A, and the valve seat is fixedly connected to the air fryer 100, so that when the solenoid valve 132A is activated, the movement of the valve body can drive the movement of the baffle 131A (for example, Figure 2 ), so that the baffle 131A reduces the cross-sectional area of ​​the exhaust channel 120 when moving downward and increases the cross-sectional area of ​​the exhaust channel 120 when moving upward, thereby achieving regulation of the cross-sectional area of ​​the exhaust channel 120.

[0041] To close the exhaust passage 120, the solenoid valve 132A can be de-energized. In this state, the portion of the valve body extending beyond the valve seat reaches its maximum length, causing the flap 131A to face the exhaust passage 120, minimizing the cross-sectional area of ​​the exhaust passage 120. At this point, because the vent 1311 faces the exhaust passage 120, the exhaust passage 120 is at least partially open, thereby balancing the pressure within the cavity 110 and preventing the air fryer 100 from becoming a pressure cooker.

[0042] If the exhaust channel 120 needs to be opened, the solenoid valve 132A can be kept in the powered state. In this state, the valve body moves to the upper end of the valve seat under the magnetic force of the electromagnetic coil, and the baffle 131A moves completely to the top of the exhaust channel, so that the cross-sectional area of ​​the exhaust channel 120 is at its maximum value.

[0043] In some embodiments, the voltage intensity of the solenoid valve 132A can be controlled to precisely adjust the positional relationship between the valve body and the valve seat, thereby adjusting the cross-sectional area of ​​the exhaust passage 120 , which will not be described in detail here.

[0044] In other embodiments, Figure 3 As shown, the driving member 132 in the regulating device 130 can be the valve seat 1321 of the solenoid valve 132B, and the blocking member 131 can be the valve body 1322 of the solenoid valve 132B. It will be appreciated that if the valve body 1322 is sufficiently large, it can directly serve as the aforementioned blocking member 131. When the solenoid valve 132B is activated, the valve body 1322 of the solenoid valve 132B moves up and down, thereby changing the cross-sectional area of ​​the exhaust passage 120.

[0045] In some other embodiments, Figure 4As shown, the driving member 132 can be a motor 132C, which is fixedly mounted on the air fryer 100. The shielding member 131 can be a baffle 131C, which is connected to the motor 132C via a connecting rod. It is understood that the motor 132C can drive the baffle 131C to rotate about the output shaft of the motor 132C, thereby controlling the baffle 131C to move closer to or further away from the exhaust passage 120. When the baffle 131C rotates to face the exhaust passage 120, the cross-sectional area of ​​the exhaust passage 120 is minimized. When the baffle 131C rotates left or right, the cross-sectional area of ​​the exhaust passage 120 gradually increases.

[0046] See also Figure 5 , Figure 5 A partial cross-sectional view of another air fryer provided in one embodiment of the present application is shown. The air fryer 200 includes a cavity 210, an exhaust duct 220, and a regulating device 230. The exhaust duct 220 is connected to the cavity 210 at one end and to the outside at the other end. The regulating device 230 is used to control the change in the cross-sectional area of ​​the exhaust duct 220.

[0047] like Figure 5 and Figure 6 As shown, the regulating device 230 may include a first baffle 231, a second baffle 232, two gears (for example, a first gear 233 and a second gear 234) arranged in meshing relationship, and a motor 235. Figure 5 and Figure 6 The first gear 233 in the middle is connected to the motor 235, the first baffle 231 and the second baffle 232 are respectively installed on the first gear 233 and the second gear 234, and the first baffle 231 and the second baffle 232 are both arranged in the exhaust channel 220. When the motor 235 drives the first gear 233 and the second gear 234 to rotate relative to each other, the first baffle 231 and the second baffle 232 move away from or towards each other to change the cross-sectional area of ​​the exhaust channel 220.

[0048] In some embodiments, as Figure 5 and Figure 6 As shown, the air vent 236 can be opened on the first baffle 231 or the second baffle 232, or a portion of the air vent 236 can be opened on the first baffle 231 and the second baffle 232 respectively, so that a complete air vent 236 is formed when the first baffle 231 and the second baffle 232 rotate to abut each other.

[0049] See also Figure 5During cooking, if exhaust duct 220 needs to be closed, motor 235 can be started in the forward direction. The output shaft of motor 235 rotates, driving first gear 233 to rotate. Since first gear 233 meshes with second gear 234, second gear 234 rotates in the opposite direction of first gear 233, causing first baffle 231 connected to first gear 233 and second baffle 232 connected to second gear 234 to approach each other until they are joined to form a complete baffle. The air vent 236 on the baffle faces exhaust duct 220, allowing exhaust duct 220 to be closed and pressure balanced by air vent 236.

[0050] See also Figure 6 If the exhaust passage 220 needs to be opened, the motor 235 is started in reverse, and the principle is the same as above, so that the first baffle 231 connected to the first gear 233 and the second baffle 232 connected to the second gear 234 move away from each other, so that the first baffle 231 and the second baffle 232 completely do not block the exhaust passage 220, so that the exhaust passage 220 is opened.

[0051] It should be noted that, through the above-mentioned gear pair structure, the two baffles 231 and 232 are rotated and combined to block the exhaust channel 220, which saves more space compared to the previous embodiment in which a single baffle rotates to block the exhaust channel.

[0052] See also Figure 7 , Figure 7 A partial cross-sectional view of another air fryer provided in one embodiment of the present application is shown. The air fryer 300 includes a cavity 310, an exhaust duct 320, and a regulating device 330. The exhaust duct 320 is connected to the cavity 310 at one end and to the outside at the other end. The regulating device 330 is used to control the change in the cross-sectional area of ​​the exhaust duct 320.

[0053] like Figure 7 As shown, the adjustment device 330 may include a fixedly connected toggle member 331 and a follower 332. The follower 332 is arranged in the exhaust channel 320. The toggle member 331 is used for the user to toggle to drive the follower 332 to move, so that the cross-sectional area of ​​the exhaust channel 320 changes.

[0054] In some embodiments, the toggle member 331 can at least partially extend out of the cooking utensil for the user to toggle, and the follower member 332 is rotatably arranged in the exhaust channel through the damping shaft so that when the user stops toggle, the follower member 332 remains in the current position and does not move.

[0055] In some embodiments, the toggle member 331 may further include a first portion 3311 and a second portion 3312, wherein the first portion 3311 is connected to the follower 332 and forms an angle with the second portion 3312, and the second portion 3312 at least partially extends out of the cooking utensil for the user to toggle. The length of the first portion 3311 may be smaller than the length of the second portion 3312. In some embodiments, such as Figure 7 As shown, the follower 332 may be provided with an air hole for balancing the air pressure.

[0056] See also Figure 8 , Figure 8 FIG. 4 shows a partial cross-sectional view of another air fryer provided by an embodiment of the present application. The air fryer 400 includes a cavity 410, a first exhaust channel 420, a second exhaust channel ( Figure 8 Not shown), the first baffle 430, the second baffle ( Figure 8 ) and an elastic adjustment device 440.

[0057] One end of the first exhaust channel 420 is connected to the cavity 410, and the other end is connected to the outside. An elastic adjustment device 440 is disposed in the first exhaust channel 420, and a first baffle 430 is disposed in the first exhaust channel 420 and between the elastic adjustment device 440 and the cavity 410. When the elastic adjustment device 440 and the first baffle 430 are in different positions, the cross-sectional area of ​​the first exhaust channel 420 varies.

[0058] One end of the second exhaust channel is connected to the cavity 410, and the other end is connected to the outside. The second baffle is set in the second exhaust channel. When the second baffle is in different positions, the cross-sectional area of ​​the second exhaust channel is different. It is understood that the second baffle and its control mechanism, not shown, can be referred to in Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 The baffle and its control mechanism shown (eg Figure 1-2 The solenoid valve and baffle shown, Figure 5-6 The gear pair and baffle shown can both serve as the second baffle and its control structure in the air fryer 400.

[0059] In some embodiments, the elastic adjustment device 440 may include a spring hinge. Figure 8 One end of the spring hinge is fixed to the cavity 410, and the other end is fixedly connected to the first baffle 430, so that when the pressure in the cavity 410 changes, the first baffle 430 can rotate around the rotation axis of the spring hinge, thereby changing the cross-sectional area of ​​the first exhaust channel 420.

[0060] Specifically, when the cooking pressure in the cavity 410 is less than or equal to the pressure threshold, under the elastic force of the spring hinge, the first baffle 430 will be pressed toward the direction of the first exhaust channel 420, that is, the first baffle 430 will abut against the outside of the cavity 410, thereby blocking the first exhaust channel 420.

[0061] The air fryer 400 is designed with two exhaust channels and two shields. Depending on different cooking conditions (e.g., cooking mode), it can switch between blocking the first exhaust channel 420 and blocking the second exhaust channel. It can also adjust the first exhaust channel 420 and the second exhaust channel simultaneously. For example, only the first exhaust channel 420 can be opened, only the second exhaust channel can be opened, or both exhaust channels can be opened or closed simultaneously.

[0062] For example, the air fryer 400 can include at least two cooking modes: a crispy roast mode and a tender roast mode. For example, when the user selects the tender roast mode, the second flap is locked and cannot move. As the cooking pressure within the cavity 410 gradually increases with the cooking temperature, the air within the cavity 410 expands, pushing the first flap 430. The first flap 430 overcomes the elastic force provided by the spring hinge, rotating about the spring hinge's axis and away from the first exhaust duct 420. At this point, the first exhaust duct 420 gradually opens, i.e., its cross-sectional area gradually increases. As the cooking pressure within the cavity 410 decreases, the elastic force provided by the spring hinge overcomes the pressure, causing the first flap 430 to gradually rotate toward its original position. Under the influence of atmospheric pressure and the cooking pressure within the cavity 410, the pressure within the cavity 410 is dynamically adjusted via the spring hinge and the first flap 430.

[0063] When the user selects the crispy cooking mode, the first flap 430 is locked and cannot move. As the cooking pressure in the cavity 410 gradually increases with the cooking temperature, the second flap's control mechanism fully opens the flap to its limit position and locks it when it reaches the limit position. After the second flap is locked until cooking is complete, the cross-sectional area of ​​the second exhaust passage remains at its maximum value.

[0064] In some embodiments, the first baffle 430 and / or the second baffle may be provided with ventilation holes for balancing the cooking pressure.

[0065] In some embodiments, the air fryers 100 to 400 may further include the following components:

[0066] ① Heating element: It is located above the cavity and is used to heat the cavity. The heating element may include but is not limited to an infrared disk or a dry-heating tube.

[0067] ② Fan: It is installed above the heating element and facing the heating element. It is used to blow the high-temperature air around the heating element into the cavity and discharge the water vapor, oil smoke or excess heat generated in the cavity to the outside of the cavity through the exhaust channel.

[0068] ③ Temperature sensor: This is located inside the cavity and is used to monitor the temperature inside the cavity in real time, allowing the air fryer to control the cooking process based on the detected temperature. There can be at least one temperature sensor.

[0069] ④ Pressure sensor: at least one pressure sensor can be set in the cavity to detect the pressure in the cavity to prevent explosion due to excessive pressure in the cavity, or to control specific cooking operations according to the pressure in the cavity.

[0070] See also Figure 9 , Figure 9 The flow chart of the cooking appliance control method provided by an embodiment of the present application is shown. The cooking appliance control method can be applied to Figure 1-4 The air fryer 100 shown in FIG. The cooking appliance control method may specifically include the following steps S110 and S120.

[0071] Step S110: When the air fryer is in the first state, controlling the cross-sectional area of ​​the exhaust passage to be within a first range.

[0072] In some embodiments, the cross-sectional area of ​​the exhaust passage may be controlled to be within a first range before the cooking environment of the cavity reaches a trigger condition.

[0073] Among them, the cooking environment refers to various data in the cavity, such as temperature, pressure, humidity, etc., which can be measured in real time through corresponding sensors (such as temperature sensors, pressure sensors, hygrometers, etc.).

[0074] The method described in this embodiment is applied to Figure 1-4 In the air fryer shown, the cooking process is controlled electrically, that is, automatically controlled by relevant electronic components in the air fryer.

[0075] In some embodiments, the air fryer may have pre-set cooking modes, and different cooking modes correspond to different cooking processes.

[0076] In some embodiments, trigger parameters can be obtained, which include at least one of the temperature, pressure and cooking time in the cavity; when the trigger parameters reach the trigger threshold, it is determined that the cooking environment of the cavity meets the trigger conditions; when the trigger parameters do not reach the trigger threshold, it is determined that the cooking environment of the cavity does not meet the trigger conditions.

[0077] When the trigger parameter is the temperature in the cavity, the trigger threshold can be set to a preset temperature (i.e., the ideal temperature that needs to be maintained when cooking ingredients). Cooking modes may include a tender baking mode and a crispy baking mode. Compared to the crispy baking mode, the tender baking mode has higher requirements on the moisture content in the air. For example, the tender baking mode requires the moisture content of the air in the cavity to be higher than the humidity threshold, while the crispy baking mode requires the moisture content of the air in the cavity to be lower than the humidity threshold. The preset temperatures corresponding to different cooking modes may be different or the same, and this application does not limit this.

[0078] The cooking appliance control method provided in the embodiment of the present application is described in detail below by taking the temperature in the cavity as an example of a trigger parameter.

[0079] In some embodiments, different cooking modes may correspond to pre-set cooking times. When using an air fryer, the user may first select a cooking mode based on actual needs (e.g., food cooking needs), then start the air fryer. The air fryer then determines the corresponding cooking time based on the user-selected cooking mode and controls the heating element to start working, rapidly raising the temperature in the cavity to cook the food.

[0080] The cooking mode for this cooking can be pre-selected by the user before starting cooking, and can be selected by using a mode selection button provided on the air fryer. There can be only one mode selection button, which can be pressed multiple times to present different options, or a function selection button can be provided for each cooking function, which is not limited here.

[0081] In some embodiments, before the cooking environment reaches a trigger condition, that is, before the temperature in the cavity reaches a preset temperature, the cross-sectional area of ​​the exhaust passage can be controlled to be within a first range.

[0082] The first range may refer to completely closing the exhaust passage, or may be a range set by the user to close most of the exhaust passage.

[0083] It is understandable that the trigger threshold is set to ensure that the temperature in the cavity of the air fryer reaches a preset temperature, so that the ingredients can be cooked. Before the trigger parameter reaches the trigger threshold (that is, the temperature in the cavity reaches the preset temperature), it is necessary to prioritize ensuring that the temperature in the cavity rises quickly to near the preset temperature. Therefore, before the temperature in the cavity reaches the preset temperature, the cross-sectional area of ​​the exhaust channel can be controlled to be in the first range (for example, completely closed) to avoid the situation where heat energy is lost with the gas, resulting in a decrease in the heating efficiency in the cavity.

[0084] Step S120: When the air fryer is in the second state, controlling the cross-sectional area of ​​the exhaust passage to be within a second range.

[0085] In some embodiments, when the cooking environment in the cavity reaches a trigger condition, the cross-sectional area of ​​the exhaust passage is controlled to be within a second range.

[0086] After the cooking environment reaches the trigger condition, in order to ensure the cooking effect of the ingredients, the temperature in the cavity needs to be maintained within a certain range near the preset temperature. Therefore, the cross-sectional area of ​​the exhaust channel can be controlled to be within the second range according to the current cooking mode.

[0087] The second range may refer to a range between a minimum value and a maximum value of the cross-sectional area of ​​the exhaust passage, or may be a range set by the user, or may refer to fully opening the exhaust passage.

[0088] As mentioned above, different cooking modes may have different cooking processes. The following takes ① crispy baking mode and ② tender baking mode as examples to describe the cooking processes respectively.

[0089] In the crispy roasting mode (1), once the temperature inside the cavity reaches the preset temperature, the moisture content in the air inside the cavity needs to be minimized to achieve a crispy roasted food. Therefore, to fully drain the moisture, the cross-sectional area of ​​the exhaust passage can be controlled to the maximum value within the second range, i.e., fully open.

[0090] For the ② tender baking mode, after the temperature in the cavity reaches the preset temperature, in order to achieve the tender baking effect of the ingredients, it is necessary to maintain a certain moisture content in the air in the cavity. Therefore, in order to reduce moisture loss, the exhaust channel can be closed. However, completely closing the exhaust channel will cause the temperature and pressure inside the cavity to continue to rise during the heating process, turning it into a pressure cooker, and the tender baking effect cannot be achieved. In order to achieve a better tender baking effect, the cross-sectional area of ​​the exhaust channel can be controlled to change periodically within the second range, so that the expanded gas is partially discharged to achieve the effect of pressure relief. At the same time, the temperature in the cavity is ensured to be within a stable range, thereby ensuring the cooking effect. Specifically, after the temperature in the cavity reaches the preset temperature, the cross-sectional area of ​​the exhaust channel can be controlled to change periodically between the maximum and minimum values ​​of the second range.

[0091] In some embodiments, after the temperature in the cavity reaches a preset temperature, the cross-sectional area of ​​the exhaust channel can be controlled to be a first area, wherein the first area is within a second range; the cooking parameters are obtained, and the cooking parameters include cooking time or cooking pressure; it is detected whether the cooking parameters meet the first change condition; when the cooking parameters meet the first change condition, the cross-sectional area of ​​the exhaust channel is controlled to be a second area, and the second area is within a second range and the second area is greater than the first area; it is detected whether the cooking parameters meet the second change condition; when the cooking parameters meet the second change condition, the operation of controlling the cross-sectional area of ​​the exhaust channel to be the first area is repeated, and the cycle is repeated until the cooking is completed (for example, the total duration of the cooking process reaches the cooking time corresponding to the tender roasting mode).

[0092] When the cooking parameter is the cooking time, when the temperature in the cavity reaches the preset temperature, the cross-sectional area of ​​the exhaust channel can be controlled to be the first area, and the timing can be continued from the current moment; it can be detected whether the continuous timing time reaches the first preset time; when the continuous timing time reaches the first preset time, the cross-sectional area of ​​the exhaust channel can be controlled to be the second area, and the timing can be restarted from the current moment; it can be detected whether the restarted continuous timing time reaches the second preset time; when the restarted continuous timing time reaches the second preset time, the steps of controlling the cross-sectional area of ​​the exhaust channel to be the first area and starting the timing from the current moment are repeated until the cooking is completed.

[0093] Among them, the first preset time can be set to be longer than the second preset time, so that the exhaust channel remains in the first area most of the time and in the second area for a short period of time, so that water vapor will not be lost too much, ensuring a better tender roasting effect.

[0094] It can be understood that by controlling the cross-sectional area of ​​the exhaust channel to change periodically, most of the water vapor evaporated from high temperature can be retained in the cavity and flow with the high-temperature air, thereby utilizing the moisture of the food itself to tenderize the surface of the food, so that the surface of the food will not be baked too dry and hard. At the same time, it can also balance the cooking pressure in the cavity to prevent the air fryer from becoming a pressure cooker.

[0095] When the cooking parameter is cooking pressure, when the temperature in the cavity reaches a preset temperature, the cross-sectional area of ​​the exhaust channel can be controlled to be at a first area; detect whether the pressure in the cavity reaches a first pressure threshold; when it is detected that the pressure in the cavity reaches the first pressure threshold, control the cross-sectional area of ​​the exhaust channel to be at a second area; detect whether the pressure in the cavity is less than or equal to the second pressure threshold, wherein the second pressure threshold is less than the first pressure threshold; when the pressure in the cavity is less than or equal to the second pressure threshold, repeat the steps of controlling the cross-sectional area of ​​the exhaust channel to be at the first area until the cooking is completed.

[0096] The first pressure threshold may be a critical value of the pressure inside the cavity, that is, exceeding the first pressure threshold may result in a greater risk, or exceeding the first pressure threshold may achieve the cooking effect of a pressure cooker; when the first pressure threshold is reached, the exhaust channel is controlled to be in the second area (for example, fully open), and the pressure in the cavity gradually decreases until it drops to the second pressure threshold. At this time, the exhaust channel is controlled to be in the first area (for example, fully closed), and the pressure in the cavity gradually increases. Through the above embodiment, the pressure in the cavity cycles back and forth between the first pressure threshold and the second pressure threshold.

[0097] The second pressure threshold needs to be slightly greater than the atmospheric pressure, which can be set by the designer according to actual cooking needs and is not limited here. Setting the pressure threshold slightly greater than the atmospheric pressure has the following advantages:

[0098] First, it improves cooking efficiency. Under conditions slightly higher than atmospheric pressure, the temperature inside the air fryer will be higher, and the food will be cooked faster, thus completing the cooking process more quickly and reducing the time the food is cooked at high temperature, thereby retaining more nutrients and taste.

[0099] Second, it prevents food from bursting. During cooking, if the gas inside the food is heated and expands, it may cause the food to burst. However, a slight increase in pressure can suppress the expansion of the gas, thus preventing the food from bursting, which helps maintain the integrity and aesthetics of the food.

[0100] In some embodiments, the exhaust passage can be kept at least partially open at all times through the air vents. During the heating process in the cavity, some expanded air can be discharged through the air vents, thereby achieving a pressure relief effect and ensuring cooking safety.

[0101] Based on the above steps S110 to S120, when the air fryer is in the first state, the cross-sectional area of ​​the exhaust channel is controlled to be within a first range; when the air fryer is in the second state, the cross-sectional area of ​​the exhaust channel is controlled to be within a second range, so that the air fryer can control the moisture content of the air in the cavity by adjusting the size of the exhaust channel. When a higher moisture content is required for cooking, moisture loss can be reduced, and the moisture of the ingredients themselves can be used for cooking without adding additional water. When a lower moisture content is required for cooking, moisture in the air can be quickly discharged to meet cooking needs.

[0102] See also Figure 10 , Figure 10 A flow chart of a cooking appliance control method according to another embodiment of the present invention is shown. The cooking appliance control method can be applied to Figure 1-4 The air fryer 100 shown in FIG. The cooking appliance control method may specifically include the following steps S210 and S220.

[0103] Step S210: In response to the air fryer starting to perform cooking, the air fryer enters the first stage, in which the regulating device regulates the cross-sectional area of ​​the exhaust passage to be within a first range.

[0104] Step S220: When the cooking environment in the cavity reaches the trigger condition, the cooking process enters the second stage corresponding to the current cooking mode. In the second stage, the regulating device regulates the cross-sectional area of ​​the exhaust passage to be within the second range.

[0105] In the embodiment of the present application, the control operations performed by the air fryer in the corresponding second stage may be different in different cooking modes, while the first stage may not distinguish between cooking modes, that is, the control operations performed by the air fryer in the first stage are the same in different cooking modes.

[0106] Specifically, the user can first select the cooking mode for this cooking according to actual needs (such as food cooking needs), and then start the air fryer. At this time, the air fryer determines the corresponding cooking time according to the cooking mode selected by the user, and controls the heating element to start cooking.

[0107] As mentioned above, different cooking modes can have different pre-set cooking times. When the air fryer starts cooking, the timer can be started immediately.

[0108] The first stage is the period from the start of cooking until the cooking environment in the cavity reaches the trigger condition. The second stage is the period from the start of cooking until the cooking environment in the cavity reaches the trigger condition until the cooking ends (i.e., the timer reaches the cooking time corresponding to the selected cooking mode).

[0109] In some embodiments, when the current cooking mode is the tender baking mode and the cooking environment in the cavity reaches the trigger condition, it enters the second stage corresponding to the tender baking mode. In the second stage corresponding to the tender baking mode, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to periodically change within the second range.

[0110] In some embodiments, when the current cooking mode is the tender roasting mode and the cooking environment in the cavity reaches the trigger condition, the first sub-stage of the second stage corresponding to the tender roasting mode is entered, wherein in the first sub-stage, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the first area; obtains cooking parameters, which include cooking time or cooking pressure; detects whether the cooking parameters meet the first change condition; when the cooking parameters meet the first change condition, enters the second sub-stage of the second stage corresponding to the tender roasting mode, wherein in the second sub-stage, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the second area, the second area is within the second range and the second area is greater than the first area; detects whether the cooking parameters meet the second change condition; when the cooking parameters meet the second change condition, enters the first sub-stage again until the current cooking is completed.

[0111] By periodically switching between the first sub-stage and the second sub-stage, the cross-sectional area of ​​the exhaust passage is controlled, ensuring a better tender roasting effect while maintaining pressure balance in the cavity.

[0112] Corresponding to the above-mentioned embodiment, in this embodiment, the cooking parameters may include cooking time or cooking pressure, the first change condition may be the first preset time or the first pressure threshold, and the second change condition may be the second preset time or the second pressure threshold.

[0113] In some embodiments, when the current cooking mode is the tender roasting mode, and the cooking parameters are the cooking time, the first change condition is the first preset time, and the second change condition is the second preset time, when the cooking environment in the cavity reaches the trigger condition, the first sub-stage in the second stage corresponding to the tender roasting mode is entered, and the timing is continuous from the current moment, wherein, in the first sub-stage, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the first area; detects whether the continuous timing time reaches the first preset time; when the continuous timing time reaches the first preset time, the second sub-stage in the second stage corresponding to the tender roasting mode is entered, and the timing is restarted from the current moment, and in the second sub-stage, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the second area; detects whether the restarted continuous timing time reaches the second preset time; when the restarted continuous timing time reaches the second preset time, re-executes the steps of entering the first sub-stage in the second stage corresponding to the tender roasting mode until the current cooking is completed.

[0114] In other embodiments, when the current cooking mode is the tender roasting mode, and the cooking parameter is the cooking pressure, the first change condition is the first pressure threshold, and the second change condition is the second pressure threshold, when the cooking environment in the cavity reaches the trigger condition, the first sub-stage in the second stage corresponding to the tender roasting mode is entered, wherein in the first sub-stage, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the first area; detects whether the pressure in the cavity reaches the first pressure threshold; when it is detected that the pressure in the cavity reaches the first pressure threshold, the second sub-stage in the second stage corresponding to the tender roasting mode is entered, wherein the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the second area; detects whether the pressure in the cavity is less than or equal to the second pressure threshold, wherein the second pressure threshold is less than the first pressure threshold; when the pressure in the cavity is less than or equal to the second pressure threshold, repeats the steps of entering the first sub-stage in the second stage corresponding to the tender roasting mode until the current cooking is completed.

[0115] In some embodiments, when the current cooking mode is the crispy baking mode and the cooking environment in the cavity reaches the trigger condition, it enters the second stage corresponding to the crispy baking mode. In the second stage corresponding to the crispy baking mode, the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the maximum value of the second range.

[0116] Among them, when judging whether the cooking environment meets the trigger conditions, the trigger parameters can be obtained, and the trigger parameters include at least one of the temperature, pressure and cooking time in the cavity; when the trigger parameters reach the trigger threshold, it is determined that the cooking environment of the cavity meets the trigger conditions; when the trigger parameters do not reach the trigger threshold, it is determined that the cooking environment of the cavity does not meet the trigger conditions.

[0117] Based on the above steps S210 to S220, in response to the air fryer starting to execute cooking, the first stage is entered, and the regulating device adjusts the cross-sectional area of ​​the exhaust channel to be within a first range; when the cooking environment in the cavity reaches the trigger condition, the second stage corresponding to the current cooking mode is entered, and the regulating device adjusts the cross-sectional area of ​​the exhaust channel to be within a second range in the second stage, so that the air fryer can adjust the size of the exhaust channel by switching between different stages, thereby controlling the moisture content of the air in the cavity. When a higher moisture content is required for cooking, moisture loss can be reduced, and the moisture of the food itself can be used for cooking without adding additional water; when a lower moisture content is required for cooking, moisture in the air can be quickly discharged to meet cooking needs.

[0118] See also Figure 11 , Figure 11 A flow chart of a cooking appliance control method according to another embodiment of the present invention is shown. The cooking appliance control method can be applied to Figure 5-6The air fryer 200 shown in FIG. The cooking appliance control method may specifically include the following steps S310 and S320.

[0119] Step S310: before the cooking environment of the cavity reaches a trigger condition, controlling the plurality of baffles to be in a preset position so that the cross-sectional area of ​​the exhaust passage is within a first range.

[0120] Step S320: When the cooking environment in the cavity reaches a trigger condition, the plurality of baffles are controlled to move according to the current cooking mode so that the cross-sectional area of ​​the exhaust passage is within a second range.

[0121] As above, the cooking appliance control method provided in the embodiment of the present application is described by taking the crispy baking mode and the tender baking mode as examples.

[0122] When the cooking environment in the cavity reaches a trigger condition and the current cooking mode is the crispy baking mode, the multiple baffles are controlled to move so that the cross-sectional area of ​​the exhaust channel is the maximum value of the second range.

[0123] Specifically, see Figure 5-6 The plurality of baffles may include a first baffle and a second baffle. Under the control of the motor, the plurality of baffles move in opposite directions to fully open the exhaust passage, that is, the cross-sectional area is the maximum value of the second range.

[0124] When the cooking environment in the cavity reaches a trigger condition and the current cooking mode is a tender roasting mode, the plurality of baffles are controlled to move periodically so that the cross-sectional area of ​​the exhaust passage changes periodically within a second range.

[0125] Specifically, when the cooking environment in the cavity reaches the trigger condition and the current cooking mode is the tender roasting mode, the first baffle and the second baffle are controlled to move toward each other so that the cross-sectional area of ​​the exhaust channel is the first area, wherein the first area is within the second range; the cooking parameters are obtained, and the cooking parameters include cooking time or cooking pressure; it is detected whether the cooking parameters meet the first change condition; when the cooking parameters meet the first change condition, the first baffle and the second baffle are controlled to move away from each other so that the cross-sectional area of ​​the exhaust channel is the second area, wherein the second area is within the second range and the second area is greater than the first area; it is detected whether the cooking parameters meet the second change condition; when the cooking parameters meet the second change condition, the steps of controlling the first baffle and the second baffle to move toward each other so that the cross-sectional area of ​​the exhaust channel is the first area are repeated until the current cooking is completed.

[0126] Corresponding to the above-mentioned embodiment, in this embodiment, the cooking parameters may include cooking time or cooking pressure, the first change condition may be the first preset time or the first pressure threshold, and the second change condition may be the second preset time or the second pressure threshold.

[0127] In some embodiments, when the current cooking mode is the tender roast mode, and the cooking parameters are the cooking time, the first change condition is the first preset time, and the second change condition is the second preset time, when the cooking environment in the cavity reaches the trigger condition and the current cooking mode is the tender roast mode, the first baffle and the second baffle are controlled to move toward each other so that the cross-sectional area of ​​the exhaust channel is the first area, and the timing is continuous from the current moment; it is detected whether the continuous timing time reaches the first preset time; when the continuous timing time reaches the first preset time, the first baffle and the second baffle are controlled to move away from each other so that the cross-sectional area of ​​the exhaust channel is the second area, and the timing is restarted from the current moment; it is detected whether the restarted continuous timing time reaches the second preset time; when the restarted continuous timing time reaches the second preset time, the steps of controlling the first baffle and the second baffle to move toward each other so that the cross-sectional area of ​​the exhaust channel is the first area, and the timing is restarted from the current moment until the current cooking is completed.

[0128] In other embodiments, when the current cooking mode is the tender roasting mode, and the cooking parameter is the cooking pressure, the first change condition is the first pressure threshold, and the second change condition is the second pressure threshold, when the cooking environment in the cavity reaches the trigger condition, the first baffle and the second baffle are controlled to move toward each other so that the cross-sectional area of ​​the exhaust channel is in the first area; detect whether the pressure in the cavity reaches the first pressure threshold; when it is detected that the pressure in the cavity reaches the first pressure threshold, control the first baffle and the second baffle to move away from each other so that the cross-sectional area of ​​the exhaust channel is in the second area; detect whether the pressure in the cavity is less than or equal to the second pressure threshold, wherein the second pressure threshold is less than the first pressure threshold; when the pressure in the cavity is less than or equal to the second pressure threshold, repeat the steps of controlling the first baffle and the second baffle to move toward each other so that the cross-sectional area of ​​the exhaust channel is in the first area until the current cooking is completed.

[0129] Among them, when judging whether the cooking environment meets the trigger conditions, the trigger parameters can be obtained, and the trigger parameters include at least one of the temperature, pressure and cooking time in the cavity; when the trigger parameters reach the trigger threshold, it is determined that the cooking environment of the cavity meets the trigger conditions; when the trigger parameters do not reach the trigger threshold, it is determined that the cooking environment of the cavity does not meet the trigger conditions.

[0130] Based on steps S310 to S320, before the cooking environment in the cavity reaches the trigger condition, the plurality of baffles are controlled to be in a preset position so that the cross-sectional area of ​​the exhaust passage is within a first range; when the cooking environment in the cavity reaches the trigger condition, the plurality of baffles are controlled to move according to the current cooking mode so that the cross-sectional area of ​​the exhaust passage is within a second range, Figure 5-6 The linkage between the multiple baffles shown ensures the cooking effects of different cooking modes while taking up less space.

[0131] See also Figure 12 , Figure 12 A flow chart of a cooking appliance control method according to another embodiment of the present invention is shown. The cooking appliance control method can be applied to Figure 7 The air fryer 300 shown in FIG. The cooking appliance control method may specifically include the following steps S410 and S430.

[0132] Step S410: prompting the user to adjust the cross-sectional area of ​​the exhaust passage to a first range.

[0133] The method described in this embodiment is applied to Figure 7 In the air fryer shown, the cooking process is controlled manually, that is, manually controlled through relevant mechanical components in the air fryer.

[0134] In an embodiment of the present application, the air fryer may have a component for prompting the user, for example, voice prompts may be provided through a speaker, or prompts may be provided to the user through a screen, etc., which is not limited in this embodiment of the present application.

[0135] When the air fryer is started, after the user selects a cooking mode, the user may be prompted to manually adjust the cross-sectional area of ​​the exhaust passage.

[0136] In some embodiments, before the cooking environment meets the triggering condition, the exhaust duct may be located in different positions in different cooking modes. The air fryer may determine, based on the cooking mode selected by the user, the position within the first range to which the user should adjust the cross-sectional area of ​​the exhaust duct, and prompt the user with the position.

[0137] For example, when the user selects the crispy baking mode, the air fryer determines that in the crispy baking mode, the exhaust duct should be in a completely closed state before the cooking environment reaches the trigger condition, that is, a prompt message such as "Please close the exhaust duct completely" is displayed on the display screen, so that the user can control the exhaust duct cross-sectional area of ​​the air fryer according to the prompt message.

[0138] Step S420: When the cross-sectional area of ​​the exhaust passage is adjusted to a first range, cooking begins.

[0139] In some embodiments, the air fryer can detect the cross-sectional area of ​​the exhaust passage.

[0140] When it is detected that the cross-sectional area of ​​the exhaust passage is adjusted to the position indicated in step S410, cooking begins and the temperature in the cavity continues to rise.

[0141] Step S430: When the cooking environment of the cavity reaches a trigger condition, prompt the user to adjust the cross-sectional area of ​​the exhaust passage to within a second range.

[0142] When the cooking environment in the cavity reaches a trigger condition, a reminder is issued to prompt the user to adjust the cross-sectional area of ​​the exhaust passage to within a second range; wherein the reminder includes at least one of a sound reminder and a light reminder.

[0143] As before, if the current cooking mode is the crispy baking mode, the user may be notified to adjust the cross-sectional area of ​​the exhaust passage to the maximum value of the second range, and the embodiments of the present application will not be described in detail here.

[0144] Based on steps S410 to S430, by sending corresponding prompt information to the user at the corresponding cooking stage, the user can timely control the cross-sectional area of ​​the exhaust channel of the air fryer, thereby regulating the pressure and moisture content in the air fryer and improving the cooking effect.

[0145] See also Figure 13 , Figure 13 A flow chart of a cooking appliance control method according to another embodiment of the present invention is shown. The cooking appliance control method can be applied to Figure 8 The air fryer 400 shown in FIG. The cooking appliance control method may specifically include the following steps S510 and S520.

[0146] Step S510: When the cooking pressure in the cavity is less than or equal to the pressure threshold, the elastic adjustment device is in the initial position, and the first baffle and the second baffle are both closed, so that the cross-sectional areas of the first exhaust channel and the second exhaust channel are both within the first range.

[0147] The method described in this embodiment is applied to Figure 8 In the air fryer shown, the cooking process is automatically controlled, that is, automatically controlled by relevant mechanical components in the air fryer.

[0148] If the cavity is closed, the temperature and pressure within the cavity are positively correlated. The cooking pressure corresponding to the ideal cooking temperature for this cooking session can be set as a pressure threshold. When the cooking pressure is less than or equal to the pressure threshold, it indicates that the temperature within the cavity has not yet reached the ideal temperature and should continue to rise. At this point, the pressure within the cavity is insufficient to overcome the elastic force provided by the elastic adjustment device, and both the first and second exhaust channels are completely closed.

[0149] Step S520: When the cooking pressure in the cavity is greater than the pressure threshold, according to the current cooking mode, the first baffle and / or the second baffle are controlled to open so that the position of the elastic adjustment device and / or the second baffle changes, and the cross-sectional area of ​​the first exhaust channel and / or the second exhaust channel is in the second range.

[0150] Different adjustment schemes can be designed for different cooking modes. For example, in the crispy baking mode, the first baffle can be locked, and the pressure and moisture in the cavity can be regulated only by the second baffle. In the tender baking mode, the second baffle can be locked, and the pressure and moisture in the cavity can be regulated only by the first baffle. Alternatively, in the tender baking mode or the crispy baking mode, the pressure and moisture in the cavity can be regulated by combining the first baffle and the second baffle. In other words, the cooking mode and the locking status of the baffles can be freely combined, and this is not limited in the embodiments of the present application.

[0151] Below, taking "setting in crispy baking mode, locking the first baffle, and regulating the pressure and moisture in the cavity only by the second baffle; in tender baking mode, locking the second baffle, and regulating the pressure and moisture in the cavity only by the first baffle" as an example, the cooking appliance control method provided in the embodiment of the present application is described.

[0152] When the cooking mode is tender roasting, the second flap can be locked using a buckle or other component to completely close the second exhaust passage, while the first flap is unlocked. The position of the elastic adjustment device changes according to the pressure difference between the internal pressure of the cavity and the external atmospheric pressure, thereby controlling the cross-sectional area of ​​the first exhaust passage to always vary within a second range.

[0153] When the cooking pressure within the cavity exceeds the pressure threshold, the temperature has reached the desired level and the pressure within the cavity is sufficient to overcome the elastic force provided by the elastic adjustment device. The pressure provided by the expanding air within the cavity overcomes the elastic force provided by the elastic adjustment device, pushing the first baffle open, thereby increasing the cross-sectional area of ​​the first exhaust channel and achieving pressure balance. After the pressure is balanced, the first baffle rebounds, reducing the cross-sectional area of ​​the first exhaust channel, thereby preventing significant moisture loss.

[0154] When the cooking mode is crispy baking mode, the first flap can be locked using a buckle or other component to completely close the first exhaust channel, while the second flap is unlocked. When the cooking pressure within the cavity exceeds the pressure threshold, the second flap can be controlled to open using methods similar to those described in the previous embodiments (e.g., via a motor, solenoid valve, etc.), so that the cross-sectional area of ​​the second exhaust channel is at the maximum value in the second range, ensuring sufficient moisture loss.

[0155] Based on steps S510 to S520, the cross-sectional area of ​​the exhaust passage can be automatically adjusted following the pressure change through the coordination of the spring hinge and the cooking pressure in the cavity, thereby ensuring the pressure balance in the cavity while ensuring the cooking effect.

[0156] The above is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as above with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present application. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
