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 in particular to a cooking appliance control method and an air fryer. Background Art

[0004] An air fryer is a machine that can use 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] Since the air fryer uses hot air to bake, the moisture on the surface of the food will evaporate. In the prior art, this moisture will be discharged through the exhaust port with the air under the action of the fan, making the surface of the food drier and drier. However, with the increasingly diversified cooking needs, if the user needs to keep a certain amount of moisture on the surface of the cooked food, the air fryer in the prior art cannot achieve this.

[0006] To deal with this situation, existing air fryers usually need to add a water replenishing 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 the user to add water every time cooking, which is inconvenient; installing a water pump also requires regular water addition, which also increases costs. Utility Model Content

[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0029] See also Figure 1 , Figure 1 The air fryer 100 includes a cavity 110, an exhaust passage 120, and a regulating device 130. One end of the exhaust passage 120 is connected to the cavity 110, and the other end is connected to the outside. The regulating device 130 is used to control the change of the cross-sectional area of ​​the exhaust passage 120.

[0030] 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, the number of the shielding member 131 is at least one, and 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.

[0031] 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.

[0032] 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 completely shield the exhaust passage 120 , and at this time the cross-sectional area of ​​the exhaust passage 120 is the largest.

[0033] 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, and the cavity 110 is in a closed state. In other embodiments, Figure 2As shown, the shielding member 131 is provided with an air hole 1311 , the minimum cross-sectional area of ​​the exhaust channel 120 is equal to the cross-sectional area of ​​the air hole 1311 , the cavity 110 is connected with the outside, and the cavity 110 is not in a closed state.

[0034] 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, and 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 value and the maximum value of its cross-sectional area.

[0035] In some embodiments, Figure 2 As shown, the driving member 132 may be a solenoid valve 132A, and the shielding member 131 may be a baffle 131A disposed at the exhaust passage 120, and the baffle 131A is in contact with the exhaust passage 120 on one side thereof 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 started, the movement of the valve body can drive the movement of the baffle 131A (for example, Figure 2 The baffle 131A reduces the cross-sectional area of ​​the exhaust passage 120 when it moves downward, and increases the cross-sectional area of ​​the exhaust passage 120 when it moves upward, thereby achieving the regulation of the cross-sectional area of ​​the exhaust passage 120.

[0036] If the exhaust passage 120 needs to be closed, the solenoid valve 132A can be kept in the off state. In this state, the portion of the valve body extending out of the valve seat reaches the limit length, so that the baffle 131A is just facing the exhaust passage 120, so that the cross-sectional area of ​​the exhaust passage 120 is at the minimum value. At this time, since the air vent 1311 is facing the exhaust passage 120, the exhaust passage 120 is at least partially opened, thereby balancing the pressure in the cavity 110, so that the air fryer 100 will not become a pressure cooker.

[0037] If the exhaust channel 120 needs to be opened, the solenoid valve 132A can be kept powered on. 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.

[0038] In some embodiments, the voltage intensity of the solenoid valve 132A can be controlled to accurately 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.

[0039] In other embodiments, Figure 3As shown, the driving member 132 in the regulating device 130 may be a valve seat 1321 of the solenoid valve 132B, and the shielding member 131 may be a valve body 1322 of the solenoid valve 132B. It is understandable that when the size of the valve body 1322 is large enough, the valve body 1322 may directly serve as the shielding member 131. When the solenoid valve 132B is started, the valve body 1322 of the solenoid valve 132B moves up and down to change the cross-sectional area of ​​the exhaust passage 120.

[0040] In some other embodiments, Figure 4 As shown, the driving member 132 may be a motor 132C, which is fixedly arranged on the air fryer 100, and the shielding member 131 may be a baffle 131C, which is connected to the motor 132C through a connecting rod. It is understandable that the motor 132C can drive the baffle 131C to rotate around the output shaft of the motor 132C, thereby controlling the baffle 131C to approach or move 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 the minimum value; when the baffle 131C rotates to the left or right, the cross-sectional area of ​​the exhaust passage 120 gradually increases.

[0041] See also Figure 5 , Figure 5 A partial cross-sectional view of another air fryer provided by an embodiment of the present application is shown. The air fryer 200 includes a cavity 210, an exhaust passage 220, and a regulating device 230. One end of the exhaust passage 220 is connected to the cavity 210, and the other end is connected to the outside. The regulating device 230 is used to control the change of the cross-sectional area of ​​the exhaust passage 220.

[0042] like Figure 5 and Figure 6 As shown, the adjustment 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, wherein any one of the first gear 233 and the second gear 234 (in Figure 5 and Figure 6 The first gear 233 in the figure 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, the first baffle 231 and the second baffle 232 are both arranged in the exhaust passage 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, so that the cross-sectional area of ​​the exhaust passage 220 changes.

[0043] In some embodiments, Figure 5 and Figure 6As shown, the air hole 236 can be opened on the first baffle 231 or the second baffle 232, or a portion of the air hole 236 can be opened on the first baffle 231 and the second baffle 232 respectively, so that a complete air hole 236 is formed when the first baffle 231 and the second baffle 232 rotate to abut each other.

[0044] See also Figure 5 During the cooking process, if the exhaust passage 220 needs to be closed, the motor 235 can be started forward, and the output shaft of the motor 235 rotates, driving the first gear 233 to rotate; since the first gear 233 is meshed with the second gear 234, the second gear 234 rotates in the opposite direction to the first gear 233, so that the first baffle 231 connected to the first gear 233 and the second baffle 232 connected to the second gear 234 are close to each other until they are spliced ​​into a complete baffle. The air vent 236 on the baffle is directly opposite to the exhaust passage 220, so that the exhaust passage 220 can be closed, and the air vent 236 is used for pressure balance.

[0045] 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 do not completely block the exhaust passage 220, so that the exhaust passage 220 is opened.

[0046] 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 single baffle rotating to block the exhaust channel in the previous embodiment.

[0047] See also Figure 7 , Figure 7 The air fryer 300 includes a cavity 310, an exhaust passage 320, and a regulating device 330. One end of the exhaust passage 320 is connected to the cavity 310, and the other end is connected to the outside. The regulating device 330 is used to control the change of the cross-sectional area of ​​the exhaust passage 320.

[0048] like Figure 7 As shown, the adjustment device 330 may include a fixedly connected toggle member 331 and a follower member 332 , wherein the follower member 332 is disposed in the exhaust channel 320 , and the toggle member 331 is used for being toggled by a user to drive the follower member 332 to move so that the cross-sectional area of ​​the exhaust channel 320 changes.

[0049] In some embodiments, the toggle member 331 can at least partially extend out of the cooking utensil for the user to toggle it, and the follower member 332 is rotatably disposed in the exhaust passage via a damping shaft so that when the user stops toggling it, the follower member 332 remains in the current position and does not move.

[0050] 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 less than the length of the second portion 3312. Figure 7 As shown, the follower 332 may be provided with an air hole for balancing the air pressure.

[0051] See also Figure 8 , Figure 8 FIG. 4 is 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.

[0052] One end of the first exhaust channel 420 is connected to the cavity 410, and the other end is connected to the outside. The elastic adjustment device 440 is arranged in the first exhaust channel 420, and the first baffle 430 is arranged 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 is different.

[0053] 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 arranged 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, which are 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 in the figure can both be used as the second baffle and its control structure in the air fryer 400.

[0054] In some embodiments, the elastic adjustment device 440 may include a spring hinge. Figure 8One 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.

[0055] 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 in 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.

[0056] The air fryer 400 is designed with two exhaust channels and two baffles, and can switch between blocking the first exhaust channel 420 and blocking the second exhaust channel according to different cooking conditions (e.g., cooking mode), and can also adjust the first exhaust channel 420 and the second exhaust channel at the same time. For example, only the first exhaust channel 420 is opened, or only the second exhaust channel is opened, or both exhaust channels are opened or closed at the same time.

[0057] For example, the air fryer 400 may include at least two cooking modes, namely, a crispy baking mode and a tender baking mode. Taking the switching of blocking the first exhaust channel 420 or blocking the second exhaust channel as an example, when the user selects the cooking mode as the tender baking mode, the second baffle is locked and cannot move. In the process in which the cooking pressure in the cavity 410 gradually increases as the cooking temperature increases, the air in the cavity 410 expands, and the expanded air pushes the first baffle 430. The first baffle 430 overcomes the elastic force provided by the spring hinge, thereby rotating around the rotation axis of the spring hinge and away from the first exhaust channel 420. At this time, the first exhaust channel 420 is gradually opened, that is, the cross-sectional area gradually increases. In the process in which the cooking pressure of the cavity 410 is continuously reduced, the elastic force provided by the spring hinge overcomes the pressure, and the first baffle 430 gradually rotates in the direction of the original position. Under the action of the atmospheric pressure and the cooking pressure in the cavity 410, the pressure in the cavity 410 is dynamically adjusted by the spring hinge and the first baffle 430.

[0058] When the user selects the crispy baking mode as the cooking mode, the first baffle 430 is locked and cannot move. When the cooking pressure in the cavity 410 gradually increases as the cooking temperature rises, the control mechanism of the second baffle controls the second baffle to fully open to the limit position and is locked when the limit position is reached. After the second baffle is locked until the cooking is finished, the cross-sectional area of ​​the second exhaust passage is kept at the maximum value.

[0059] In some embodiments, the first baffle 430 and / or the second baffle may be provided with air holes for balancing the cooking pressure.

[0060] In some embodiments, the air fryers 100 to 400 may further include the following components:

[0061] ① Heating element: It is arranged above the cavity and is used to heat the cavity. The heating element may include but is not limited to an infrared plate or a dry-burning tube.

[0062] ② Fan: It is installed above the heating element and directly 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.

[0063] ③ Temperature sensor: It is set inside the cavity and used to detect the temperature inside the cavity in real time, so that the air fryer can control the specific cooking operation according to the detected real-time temperature. The number of temperature sensors can be at least one.

[0064] ④ Pressure sensor: at least one pressure sensor can be arranged 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.

[0065] See also Fig. 9 , Fig. 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. The cooking appliance control method may specifically include the following steps S110 and S120.

[0066] Step S110: before the cooking environment of the cavity reaches a trigger condition, controlling the cross-sectional area of ​​the exhaust passage to be within a first range.

[0067] 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.).

[0068] 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, it is automatically controlled through relevant electronic components in the air fryer.

[0069] In some embodiments, the air fryer may have a pre-set cooking mode, and different cooking modes correspond to different cooking processes.

[0070] In some embodiments, 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 parameter reaches the trigger threshold, it is determined that the cooking environment of the cavity meets the trigger condition; when the trigger parameter does not reach the trigger threshold, it is determined that the cooking environment of the cavity does not meet the trigger condition.

[0071] 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 crisp baking mode. Compared with the crisp 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 crisp 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.

[0072] The cooking appliance control method provided in the embodiment of the present application is described in detail below by taking the trigger parameter being the temperature in the cavity as an example.

[0073] In some embodiments, different cooking modes may correspond to preset cooking times. When using the air fryer, the user may first select the cooking mode for this cooking according to actual needs (e.g., 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 working, so that the temperature in the cavity rises rapidly to cook the food.

[0074] The cooking mode for this cooking can be pre-selected by the user before starting cooking, and can be selected through a mode selection button set on the air fryer. There can be only one mode selection button, and different options can be presented by pressing it multiple times; or a function selection button can be set for each cooking function, which is not limited here.

[0075] 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.

[0076] 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.

[0077] 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 as to cook the food. Before the trigger parameter reaches the trigger threshold (that is, the temperature in the cavity reaches the preset temperature), it is necessary to prioritize the temperature in the cavity to quickly rise 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.

[0078] Step S120: 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.

[0079] After the cooking environment reaches the trigger condition, in order to ensure the cooking effect of the food, the temperature in the cavity needs to be kept within a certain range near the preset temperature. Therefore, the cross-sectional area of ​​the exhaust passage can be controlled to be within the second range according to the current cooking mode.

[0080] 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 a user, or may be to fully open the exhaust passage.

[0081] 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.

[0082] For the ① crispy roasting mode, when the temperature in the cavity reaches the preset temperature, in order to achieve the crispy roasting effect of the food, the moisture content in the air in the cavity needs to be reduced as much as possible. Therefore, in order to fully lose moisture, the cross-sectional area of ​​the exhaust channel can be controlled to be the maximum value of the second range, that is, it is fully opened.

[0083] 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 water 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, and 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 value and the minimum value of the second range.

[0084] In some embodiments, after the temperature in the cavity reaches a preset temperature, the cross-sectional area of ​​the exhaust channel is 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 baking mode).

[0085] 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 has reached 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 has reached 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 continuously from the current moment are repeated until the cooking is finished.

[0086] The first preset time length can be set to be greater than the second preset time length, so that the exhaust passage 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, thereby ensuring a better tender roasting effect.

[0087] It can be understood that by controlling the cross-sectional area of ​​the exhaust passage 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 in 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, the cooking pressure in the cavity can be balanced to prevent the air fryer from becoming a pressure cooker.

[0088] 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 step of controlling the cross-sectional area of ​​the exhaust channel to be at the first area until the cooking is completed.

[0089] Among them, the first pressure threshold can be a critical value of the pressure inside the cavity, that is, when exceeding the first pressure threshold, a greater risk may occur, or when exceeding the first pressure threshold, the cooking effect of the pressure cooker may be achieved; 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 implementation, the pressure in the cavity cycles back and forth between the first pressure threshold and the second pressure threshold.

[0090] 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 to be slightly greater than the atmospheric pressure has the following advantages:

[0091] First, improve 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 nutrition and taste.

[0092] Second, prevent food from bursting. During the cooking process, if the gas inside the food is heated and expands, it may cause the food to burst. However, a slightly increased pressure can suppress the expansion of the gas and prevent the food from bursting, which helps maintain the integrity and aesthetics of the food.

[0093] In some embodiments, the exhaust passage can be kept at least partially open at all times through the air holes. During the heating process in the cavity, part of the expanded air can be discharged through the air holes, thereby achieving a pressure relief effect and ensuring cooking safety.

[0094] Based on the above steps S110 to S120, by controlling the cross-sectional area of ​​the exhaust channel to be within a first range before the cooking environment in the cavity reaches the trigger condition; and controlling the cross-sectional area of ​​the exhaust channel to be within a second range when the cooking environment in the cavity reaches the trigger condition, 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.

[0095] See also Fig.10 , Fig.10 A flow chart of a cooking appliance control method provided by another embodiment of the present application is shown. The cooking appliance control method can be applied to Figure 1-4The air fryer 100 shown. The cooking appliance control method may specifically include the following steps S210 and S220.

[0096] Step S210: In response to the air fryer starting to perform cooking, entering the first stage, in which the regulating device adjusts the cross-sectional area of ​​the exhaust passage to be within a first range.

[0097] Step S220: When the cooking environment in the cavity reaches the trigger condition, entering the second stage corresponding to the current cooking mode, in which the regulating device adjusts the cross-sectional area of ​​the exhaust passage to be within the second range.

[0098] 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.

[0099] 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.

[0100] As mentioned above, different cooking modes can have different pre-set cooking times. When the air fryer starts cooking, the timing can be started immediately.

[0101] The process from the start of cooking to the cooking environment in the cavity reaching the trigger condition is the first stage. The process from the start of cooking to the end of cooking (i.e., the timing time reaches the cooking time corresponding to the selected cooking mode) is the second stage.

[0102] 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 change periodically within the second range.

[0103] In some embodiments, when the current cooking mode is the tender roast mode and the cooking environment in the cavity reaches the trigger condition, the first sub-stage in the second stage corresponding to the tender roast 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, the cooking parameters 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 roast mode, 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.

[0104] By periodically switching between the first sub-stage and the second sub-stage, the cross-sectional area of ​​the exhaust passage is controlled, ensuring that a better tender roasting effect is achieved while the pressure in the cavity is balanced.

[0105] 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 a first preset time or a first pressure threshold, and the second change condition may be a second preset time or a second pressure threshold.

[0106] 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, the first sub-stage in the second stage corresponding to the tender roast 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 roast 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 roast mode until the current cooking is completed.

[0107] In other embodiments, when the current cooking mode is the tender roast 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 roast 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 roast mode is entered, and the regulating device adjusts the cross-sectional area of ​​the exhaust channel to the second area in the second sub-stage; 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 roast mode until the current cooking is completed.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] See also Fig.11 , Fig.11 A flow chart of a cooking appliance control method provided by another embodiment of the present application is shown. The cooking appliance control method can be applied to Figure 5-6The air fryer 200 shown. The cooking appliance control method may specifically include the following steps S310 and S320.

[0112] Step S310: before the cooking environment of the cavity reaches a trigger condition, control 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.

[0113] 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.

[0114] 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.

[0115] When the cooking environment in the cavity reaches a trigger condition and the current cooking mode is a crispy baking mode, the plurality of baffles are controlled to move so that the cross-sectional area of ​​the exhaust passage is a maximum value within a second range.

[0116] 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.

[0117] 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.

[0118] 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 the cooking time or the 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.

[0119] 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 a first preset time or a first pressure threshold, and the second change condition may be a second preset time or a second pressure threshold.

[0120] 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 continued 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 continued 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 continued from the current moment are repeated until the current cooking is completed.

[0121] 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; it is detected 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 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 in the second area; it is detected 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, 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 are repeated until the current cooking is completed.

[0122] 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.

[0123] Based on step S310 to step 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 occupying less space.

[0124] See also Fig.12 , Fig.12 A flow chart of a cooking appliance control method provided by another embodiment of the present application is shown. The cooking appliance control method can be applied to Figure 7 The air fryer 300 shown. The cooking appliance control method may specifically include the following steps S410 and S430.

[0125] Step S410: prompting the user to adjust the cross-sectional area of ​​the exhaust passage to a first range.

[0126] The method described in this embodiment is applied to Figure 7 In the air fryer shown, the cooking process is controlled manually, that is, it is manually controlled through relevant mechanical components in the air fryer.

[0127] In an embodiment of the present application, the air fryer may have a component for prompting the user, for example, a voice prompt may be provided through a speaker, or a prompt may be provided to the user through a screen, etc., which is not limited in the embodiment of the present application.

[0128] 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.

[0129] In some embodiments, before the cooking environment reaches the trigger condition, the exhaust passage may be at different positions in different cooking modes. The air fryer may determine, based on the cooking mode selected by the user, to which position in the first range the user should adjust the cross-sectional area of ​​the exhaust passage, and prompt the user with the position.

[0130] 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.

[0131] Step S420: When the cross-sectional area of ​​the exhaust passage is adjusted to a first range, cooking begins.

[0132] In some embodiments, the air fryer can detect the cross-sectional area of ​​the exhaust passage.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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 herein.

[0137] Based on step S410 to step 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 to improve the cooking effect.

[0138] See also Fig.13 , Fig.13 A flow chart of a cooking appliance control method provided by yet another embodiment of the present application is shown. The cooking appliance control method can be applied to Figure 8 The air fryer 400 shown. The cooking appliance control method may specifically include the following steps S510 and S520.

[0139] 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.

[0140] The method described in this embodiment is applied to Figure 8 In the air fryer shown, the cooking process is automatically controlled, that is, it is automatically controlled through relevant mechanical components in the air fryer.

[0141] If the cavity is in a closed state, the temperature and pressure in the cavity are positively correlated. The cooking pressure corresponding to the ideal temperature of this cooking can be set as the pressure threshold. When the cooking pressure is less than or equal to the pressure threshold, it means that the temperature in the cavity has not reached the ideal temperature and should continue to rise. At this time, the pressure in the cavity is not enough to overcome the elastic force provided by the elastic adjustment device, and the first exhaust channel and the second exhaust channel are both in a completely closed state.

[0142] 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 is 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 within the second range.

[0143] Different adjustment schemes can be designed for different cooking modes. For example, it can be set that in the crispy baking mode, the first baffle is locked, and the pressure and moisture in the cavity are 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. It is also possible to regulate the pressure and moisture in the cavity by combining the first baffle and the second baffle in the tender baking mode or the crispy baking mode. That is, the cooking mode and the locking status of the baffle can be freely combined, and the embodiments of the present application are not limited here.

[0144] The following describes the cooking appliance control method provided in the embodiment of the present application by taking "setting in the crispy baking mode, locking the first baffle, and only using the second baffle to regulate the pressure and moisture in the cavity; in the tender baking mode, locking the second baffle, and only using the first baffle to regulate the pressure and moisture in the cavity" as an example.

[0145] When the cooking mode is tender roasting mode, the second baffle can be locked by means of a buckle or other components to control the second exhaust channel to be in a completely closed state, while the first baffle is in an unlocked state. 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 channel to always change within the second range.

[0146] When the cooking pressure in the cavity is greater than the pressure threshold, it means that the temperature has risen to the ideal temperature, and the pressure in the cavity is sufficient to overcome the elastic force provided by the elastic adjustment device. Under the pressure provided by the air expanding in the cavity, the elastic force provided by the elastic adjustment device is overcome to push the first baffle open, thereby increasing the cross-sectional area of ​​the first exhaust channel and achieving the effect of balancing the pressure. After the pressure is balanced, the first baffle rebounds, thereby reducing the cross-sectional area of ​​the first exhaust channel, thereby preventing serious loss of moisture.

[0147] When the cooking mode is the crispy baking mode, the first baffle can be locked by means of components such as buckles, and the first exhaust channel can be controlled to be in a completely closed state, while the second baffle is in an unlocked state. When the cooking pressure in the cavity is greater than the pressure threshold, the second baffle can be controlled to open by means of the method described in the above embodiments (e.g., by means of a motor, a solenoid valve, etc.), so that the cross-sectional area of ​​the second exhaust channel is at the maximum value of the second range, thereby ensuring sufficient loss of moisture.

[0148] Based on step S510 to step S520, through the coordination of the spring hinge and the cooking pressure in the cavity, the cross-sectional area of ​​the exhaust passage can be automatically adjusted following the pressure change, thereby ensuring the pressure balance in the cavity while ensuring the cooking effect.

Although the present application has been disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technical personnel in the field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present application.
