[0061] Embodiment 1

[0062] The present embodiment provides a cooking device, which can cook food by hot steam, thereby meeting the user's demand for food steaming. At the same time, it can realize automatic door opening and closing operation, thereby improving the user experience of the cooking device.

[0063] Specifically, Figures 1 to 3 As shown, the cooking device comprises a body 2, a hinge mechanism 4, a door 3 and an ejection mechanism 1. The body 2 has a cooking cavity 211 with an open front side, and the lower end of the door 3 is rotatably mounted on the front side of the body 2 through the hinge mechanism 4, so that the door 3 can be rotated relative to the body 2 to open or close the cooking cavity 211. The ejection mechanism 1 is mounted on the top of the body 2 and has a push rod 11 that can move in the front-to-back direction, and the push rod 11 has a first extension stroke for pushing the door 3 forward to flip to a first preset angle and a second extension stroke for pushing the door 3 to flip to a second preset angle, the first preset angle is smaller than the second preset angle, and the first extension stroke is smaller than the second extension stroke.

[0064] The hinge mechanism 4 can overcome the gravity of the door 3 when the push rod 11 retracts and the flip angle of the door 3 is less than or equal to a first preset angle so that the door 3 closes the cooking cavity 211, and when the flip angle of the door 3 is greater than or equal to a second preset angle, the door 3 slowly opens the cooking cavity 211 under the cooperation of gravity and the hinge mechanism 4.

[0065] The cooking device provided in this embodiment is provided with a hinge mechanism 4 and an ejection mechanism 1. When the push rod 11 moves forward to the first extension stroke, the door 3 can be flipped relative to the body 2 at a first preset angle, so that an exhaust opening for exhaust is formed between the top of the door 3 and the front side of the body 2, so that the hot steam in the cooking cavity 211 can be discharged to the external environment through the exhaust opening, thereby improving the exhaust speed and efficiency, avoiding excessive humidity in the cooking cavity 211 affecting the subsequent cooking process, improving the humidity control accuracy in the cooking cavity 211, and also avoiding excessive hot steam in the cooking cavity 211 when the door 3 is opened, resulting in steam blowing on the face and scalding the user The problem arises; at the same time, when the push rod 11 retracts from the first extension stroke, the machine door 3 can be automatically closed under the action of the hinge mechanism 4, thereby realizing the automatic closing operation of the machine door 3 after exhaust, improving the automaticity of door closing, improving the continuity and reliability of cooking, and improving the user experience of the cooking equipment; furthermore, when the push rod 11 extends forward to the second extension stroke, the machine door 3 can be pushed open to a second preset angle relative to the machine body 2 under the pushing action of the push rod 11, so that the machine door 3 can be gradually and slowly opened under the action of the hinge mechanism 4 and the gravity of the machine door 3, realizing the automatic door opening operation of the machine door 3, improving the convenience of opening the machine door 3, and improving the degree of automation of the cooking equipment.

[0066] It is worth noting that the door 3 has a critical opening angle. When the opening angle of the door 3 is less than the critical opening angle, the door 3 can be reset and closed under the action of the hinge mechanism 4. When the opening angle of the door 3 is greater than the critical opening angle, the door 3 can be flipped forward to be fully opened. The first preset angle is less than the critical opening angle, and the second preset angle is greater than the critical opening angle.

[0067] Generally speaking, the critical opening angle is 6° to 8°, but it is worth noting that the critical opening angle is related to the structure of the hinge mechanism 4 and the structure of the door 3, and this embodiment does not limit the specific value of the critical opening angle.

[0068] In this embodiment, 0.5°≤the first preset angle≤6°, so as to better ensure that the hinge mechanism 4 can drive the door 3 to close after the door 3 is opened to the first preset angle, avoid the problem that the door 3 is relatively difficult to close due to the first preset angle being close to the critical opening angle, ensure the smoothness and reliability of closing the door 3, and reduce the influence of processing errors or assembly errors of the hinge mechanism 4 on automatic door closing.

[0069] Furthermore, 7°≤the second preset angle≤10°, so as to realize the automatic opening of the door 3 while avoiding the problem that the second preset angle is too large and causes a larger second extension stroke requirement for the push rod 11, thereby reducing the size requirement for the ejection mechanism 1 and improving the overall structural compactness of the cooking equipment.

[0070] The machine body 2 includes an inner pot 21 with an open front side and a housing surrounding the outer side of the inner pot 21. The inner cavity of the inner pot 21 forms a cooking cavity 211, and the ejection mechanism 1 is installed between the housing and the top of the inner pot 21. When the push rod 11 is in a retracted state, the push rod 11 extends forward to a preset length of the front side of the inner pot 21, thereby shortening the distance between the push rod 11 and the machine door 3 when the push rod 11 is in a retracted state, thereby shortening the stroke length of the first extension stroke for pushing the machine door 3 open to a first preset angle, increasing the speed at which the machine door 3 is pushed open, thereby improving the automatic door opening and closing control speed and control accuracy of the cooking device, and improving the user experience of the cooking device.

[0071] Specifically, the door 3 further includes a front frame 22 surrounding the front outer side of the inner liner 21, and the front frame 22 protrudes forward from the front opening of the inner liner 21. A front plate 25 is connected between the periphery of the front opening of the inner liner 21 and the front frame 22 to close the gap between the front frame 22 and the inner liner 21. When the push rod 11 is in the retracted state, the front end of the push rod 11 extends forward from the front plate 25. It is worth noting that the structure of the door 3 and the body 2 can be set with reference to the prior art, which is not the focus of the present invention and will not be repeated here.

[0072] Furthermore, when the push rod 11 is in the retracted state, the front end of the push rod 11 extends out of the front plate 25 by a length of 0 mm to 3 mm, so as to avoid the push rod 11 extending too long to interfere with the closing of the machine door 3 .

[0073] In order to improve the installation convenience of the ejection mechanism 1, the body 2 also includes a top support plate 23 located above the inner pot 21. The cooking device has a steam condensation device 5, which includes a heat dissipation fan 51 and a hood 52. The hood 52 has a heat dissipation air duct inside. The heat dissipation air duct is connected to the cooking cavity 211 through a steam pipe. The heat dissipation fan 51 guides the external cooling air flow into the heat dissipation air duct, and at the same time promotes the steam in the cooking cavity 211 to enter the heat dissipation air duct, so that the external cooling air flow can dissipate heat and condense the steam. The steam condensation device 5 is installed on the upper side of the top support plate 23 and is located inside the casing to utilize the space between the top of the inner pot 21 and the casing, and reduce the size of the cooking device in the left and right directions. The specific structure of the steam condensation device 5 can be set with reference to the prior art, which is not the focus of this embodiment, and this embodiment does not limit or elaborate on it.

[0074] The left and right sides of the top support plate 23 extend outward from the inner pot 21 in the left and right directions, the ejection mechanism 1 is installed on the top support plate 23 and is located outside the left or right side of the inner pot 21, and the push rod 11 is located below the top support plate 23. This arrangement can avoid interference between the ejection mechanism 1 and the steam condensation device 5 above the top support plate 23, improve the rationality of the internal structure layout of the cooking device, and improve the compactness of the structure; at the same time, it can also reduce the impact of the gas discharged from the exhaust port of the heat dissipation duct on the ejection mechanism 1, and improve the safety and reliability of the ejection mechanism 1.

[0075] In another embodiment, the ejection mechanism 1 can be installed on the upper side of the top support plate 23 and located on the left or right side of the front end of the top support plate 23. In another embodiment, the ejection mechanism 1 can also be installed on the upper end of the wind cover 52 and located in the middle of the machine body 2 in the left-right direction.

[0076] The cooking device further includes a steam generator and a water tank 6, wherein the water tank 6 is connected to the water inlet of the steam generator to supply water to the steam generator, and the steam outlet of the steam generator is connected to the cooking cavity 211 to provide steam to the cooking cavity 211. In this embodiment, the water tank 6 is mounted on the top support plate 23, and the water tank 6 and the ejection mechanism 1 are respectively located on the left and right sides of the top support plate 23, thereby avoiding interference between the ejection mechanism 1 and the water tank 6.

[0077] Furthermore, in order to improve the installation convenience of the ejection mechanism 1, an installation opening 231 is provided on the top support plate 23, and a mounting seat 13 is provided on the upper side of the fixed component of the ejection mechanism 1. The mounting seat 13 is inserted into the installation opening 231, and the mounting seat 13 has fixed ears on opposite sides. The fixed ears are placed on the upper side of the top support plate 23 and are detachably connected to the top support plate 23, and the fixed component is partially located in the installation opening 231. This arrangement allows the fixed component of the ejection mechanism 1 to be partially located in the installation opening 231, thereby increasing the height of the push rod 11 without changing the size of the ejection mechanism 1, so that the action position of the push rod 11 and the machine door 3 is as close to the top of the machine door 3 as possible, so as to reduce the push force required by the push rod 11 to push the machine door 3 open, and improve the convenience of the ejection mechanism 1 pushing the machine door 3.

[0078] Furthermore, the left and right sides of the top support plate 23 are folded downward to form folded edges 232, and the ejection mechanism 1 is located between the folded edges 232 and the liner 21, so that the folded edges 232 shield and protect the ejection mechanism 1. In other embodiments, the fixed component of the ejection mechanism 1 can also be detachably connected to the lower side of the top support plate 23, that is, the ejection mechanism 1 is installed as a whole below the top support plate 23.

[0079] In this embodiment, the ejection mechanism 1 is a push rod motor, and the motor body 12 of the ejection mechanism 1 forms a fixed component. In other embodiments, the ejection mechanism 1 can also adopt other existing structures that can realize the extension and retraction of the push rod 11, and the present invention does not limit the specific structure of the ejection mechanism 1.

[0080] like Figure 4 As shown, in this embodiment, the body 2 further includes a base 24, which is located at the lower side of the inner container 21 and connected to the housing and the front frame 22. The specific structure of the body 2 can be set with reference to the prior art, and this embodiment does not limit or elaborate on this.

[0081] like Figures 5 to 10 As shown, the hinge mechanism 4 includes a fixed hinge arm 41, a rotating hinge arm 42 and a force-applying assembly. The fixed hinge arm 41 is mounted on the bottom of the machine body 2, the rotating hinge arm 42 is mounted on the machine door 3, and the lower end of the rotating hinge arm 42 is hinged to the fixed hinge arm 41 through a first hinge shaft 45; the force-applying assembly is mounted on the fixed hinge arm 41, and the force-applying assembly can apply a first force to the machine door 3 to prevent the machine door 3 from turning downward when the turning angle of the machine door 3 relative to the machine body 2 is less than or equal to a first preset angle, so that the machine door 3 returns to a closed state under the first force; the force-applying assembly can apply a second force to the machine door 3 to prevent the machine door 3 from turning downward when the machine door 3 is opened to a second preset angle relative to the machine body 2, so that the machine door 3 is slowly opened under the action of gravity and the second force.

[0082] Specifically, the force-applying assembly includes a first force-applying assembly 43 and a second force-applying assembly 44. The first force-applying assembly 43 is installed on the fixed hinge arm 41 and has a force-applying state acting on the rotating hinge arm 42 and a separated state separated from the rotating hinge arm 42; the second force-applying assembly 44 is connected between the fixed hinge arm 41 and the rotating hinge arm 42, and the second force-applying assembly 44 has an initial state in which no obstructing force is applied to the rotating hinge arm 42 and a rotation-blocking state in which an obstructing force is applied to the rotating hinge arm 42. When the angle at which the door 3 is flipped relative to the machine body 2 is less than or equal to the first preset angle, the first force-applying assembly 43 is in a force-applying state and the second force-applying assembly 44 is in an initial state; when the angle at which the door 3 is flipped relative to the machine body 2 is greater than or equal to the second preset angle, the first force-applying assembly 43 is in a separated state and the second force-applying assembly 44 is in a rotation-blocking state. That is, the first force-applying assembly 43 and the second force-applying assembly 44 are respectively used to apply force to the door 3 when the door 3 is flipped at different angles, which is more conducive to the control of the force applied to the door 3.

[0083] The first force-applying assembly 43 includes a first elastic member 431, a first sliding member 432, and a roller 433 mounted on the first sliding member 432. The first sliding member 432 extends in the left-right direction and can be slidably mounted on the fixed hinge arm 41 in the front-back direction; the first elastic member 431 extends in the front-back direction, and the rear end of the first elastic member 431 is connected to the fixed hinge arm 41, and the front end of the first elastic member 431 is fixed to the first sliding member 432. The second force-applying assembly 44 includes a second sliding member 442 and a second elastic member 441, the second sliding member 442 can be slidably mounted on the fixed hinge arm 41 in the front-back direction, and the front end of the second sliding member 442 is hinged to the fixed hinge arm 41 through a second hinge shaft 46, and the second hinge shaft 46 is arranged at intervals on the rear side of the first hinge shaft 45; the second elastic member 441 extends in the front-back direction, and the rear end of the second elastic member 441 is fixed to the fixed hinge arm 41, and the front end of the second elastic member 441 is connected to the second sliding member 442.

[0084] A pressing portion 421 is provided at the rear side of the lower end of the rotating hinge arm 42. The pressing portion 421 has a pressing groove. When the angle at which the door 3 is turned over is less than or equal to the first preset angle, the pressing portion 421 is located above and behind the hinge axis of the fixed hinge arm 41, the roller 433 is pressed in the pressing groove, and the first elastic member 431 is in a compressed state, while the second elastic member 441 is basically in a naturally extended state. The roller 433 maintains a position of pressing the pressing portion 421 downward under the elastic force of the first elastic member 431, so as to prevent the pressing portion 421 from turning over upward, thereby preventing the rotating hinge arm 42 and the door 3 from rotating.

[0085] When the door 3 continues to flip downward, the pressing force of the pressing portion 421 on the roller 433 overcomes the elastic force of the first elastic member 431, so that the roller 433 moves backward to pass over the pressing portion 421 and disengage from the pressing portion 421, so that the first force-applying assembly 43 is in a separated state. The second hinge shaft 46 moves forward due to the rotation of the rotating hinge arm 42, pulling the second sliding member 442 to slide forward, so that the second elastic member 441 is in an extended state, and then the second elastic member 441 applies a force to the second sliding member 442 to prevent the second sliding member 442 from sliding forward, so that the second sliding member 442 applies a force to the second hinge shaft 46 to prevent the second hinge shaft 46 from moving forward, and then applies a force to the rotating hinge arm 42 to prevent the rotating hinge arm 42 from continuing to rotate downward.

[0086] It is worth noting that the specific structure of the hinge mechanism 4 can be set with reference to the existing technology, and the structure of the hinge mechanism 4 provided in this embodiment is only an exemplary structure. The existing structure of the hinge mechanism 4 that can force the door 3 to close when the flip angle of the door 3 is less than or equal to the first preset angle and slowly open the door 3 when the flip angle of the door 3 is greater than or equal to the second preset angle can be applied to the present invention.

[0087] Embodiment 2

[0088] This embodiment provides a control method for a cooking device to achieve exhaust and door opening control of the cooking device, thereby improving the user experience of the cooking device.

[0089] The control method provided in this embodiment is applied to the cooking device as in the first embodiment, and this embodiment will not describe the specific structure of the cooking device in detail.

[0090] like Fig.11 As shown, the control method includes:

[0091] When the preset exhaust condition is met, the push rod 11 is controlled to extend forward to a first extension stroke, so that the door 3 is pushed open and flipped to a first preset angle;

[0092] When the preset door opening condition is met, the control push rod 11 is extended forward by a second extension stroke to open the door 3 .

[0093] The control method of the cooking device provided by the present invention, when the preset exhaust condition is met, the machine door 3 is opened to a first preset angle relative to the machine body 2, so that a larger exhaust opening can be formed between the machine body 2 and the machine door 3, thereby increasing the exhaust speed, avoiding excessive humidity in the cooking cavity 211 and affecting the cooking experience, and improving the humidity control accuracy in the cooking cavity 211; at the same time, it can also avoid the problem of steam blowing in the face when the door is opened after cooking; at the same time, when the push rod 11 retracts from the first extension stroke, the machine door 3 can be automatically switched to a closed state under the action of the hinge mechanism 4, thereby improving the convenience and reliability of closing the machine door 3 after exhaust; furthermore, after the preset door opening condition is met, the machine door 3 can be pushed open by the push rod 11 to the second preset angle, so that after the machine door 3 is pushed open, the machine door 3 can be gradually opened under the action of gravity, realizing the automatic door opening operation of the machine door 3, and improving the convenience of the door opening operation of the machine door 3.

[0094] In this embodiment, the preset door opening condition includes: receiving a door opening command.

[0095] Specifically, the user can send a door opening command to the controller of the cooking device through touch panel interaction, mobile APP, button selection or voice, and when the controller receives the door opening command, it determines that the preset door opening conditions are met.

[0096] In this embodiment, the preset exhaust conditions include a first preset exhaust condition and a second preset exhaust condition, wherein the first preset exhaust condition includes: the humidity value in the cooking cavity 211 is greater than or equal to the first preset humidity value; the second preset exhaust condition includes: the remaining cooking time is less than or equal to the preset time.

[0097] That is, during the cooking process, if the humidity in the cooking cavity 211 is high and exceeds the humidity requirement for cooking, exhaust is required to reduce the humidity in the cooking cavity 211, thereby controlling the humidity in the cooking cavity 211, improving the humidity control accuracy in the cooking cavity 211, better meeting cooking requirements, and improving the cooking experience. At the same time, when cooking is about to end, the cooking cavity 211 can be exhausted to avoid the problem of hot steam blowing in the face when cooking is finished and the door 3 is opened, causing burns or poor user experience, thereby improving the safety and user experience of the cooking device.

[0098] In order to judge the first preset exhaust condition, the cooking equipment has a humidity detection device, which is used to detect the humidity in the cooking cavity 211. The humidity detection device is communicatively connected to the controller, and the humidity value detected by the humidity detection device is sent to the controller. The controller judges whether the first preset exhaust condition is met based on the comparison between the humidity value and the first preset humidity value.

[0099] It is worth noting that the first preset humidity is not a fixed value built into the controller, and the value of the first preset humidity is related to the cooking mode and the cooking stage. For example, when the cooking mode is the fruit and vegetable drying mode, when the humidity value in the cooking cavity 211 reaches a certain preset humidity value, exhaust is required to meet the drying requirements, and because each fruit and vegetable contains different moisture and the drying speed is different, the first preset humidity value is different; and when the cooking mode is the baking mode, if the humidity in the cooking cavity 211 is greater than the preset humidity value, exhaust is required to avoid the cooking cavity 211 from being too wet and affecting the taste of the cooking, and the preset humidity value is different from the humidity value of fruit and vegetable drying; for another example, in a cooking scene where the humidity value needs to be precisely controlled, if the humidity of the cooking cavity 211 is greater than the humidity required for the cooking degree, exhaust is required quickly to meet the precise control of the humidity, and the humidity values ​​required for different cooking stages are different, resulting in different humidity values ​​that meet the first preset exhaust condition.

[0100] That is, in this embodiment, the control method further includes:

[0101] Identify cooking modes;

[0102] determining cooking parameters based on the cooking mode;

[0103] Based on the cooking parameters, a first preset humidity value is determined.

[0104] Among them, cooking parameters include cooking temperature, cooking humidity and cooking time.

[0105] In this embodiment, the control method also includes: after the door 3 is pushed open and flipped to a first preset angle due to exhaust, if the preset exhaust conditions and the preset door opening conditions are no longer met, the push rod 11 is controlled to retract so that the hinge mechanism 4 drives the door 3 to close.

[0106] That is, during the exhaust process, it is detected in real time whether the preset door opening conditions and the preset exhaust conditions are met. If the door does not need to be opened and exhaust is no longer needed at this time, the push rod 11 is controlled to retract to achieve automatic closing of the machine door 3, thereby avoiding the problem of dust or foreign matter entering the cooking chamber 211 due to the machine door 3 being opened for a long time.

[0107] Specifically, the control method further includes:

[0108] If the door 3 is pushed open and flipped to the first preset angle due to exhaust, it is first determined whether the preset door opening condition is met. If the preset door opening condition is currently met, the push rod 11 is controlled to extend forward to the second extension stroke;

[0109] If the preset door opening condition is not met at present, it is determined whether the preset exhaust condition is met. If the preset exhaust condition is not met, the push rod 11 is controlled to retract. If the preset exhaust condition is met, the current exhaust state is maintained.

[0110] That is, during the process of opening the door to exhaust, if the preset door opening conditions are met, the push rod 11 is controlled to extend to fully open the door 3, thereby meeting the user's need to open the door and improving the user experience; if the preset door opening conditions are not met, it indicates that the current user has no need to open the door, and when the preset exhaust conditions are not met, the door 3 should be closed.

[0111] Specifically, the control method includes: when the door 3 is pushed open due to meeting the first preset exhaust condition, if the humidity value in the cooking cavity 211 is less than or equal to the first preset humidity value and the preset door opening condition is not met at present, the push rod 11 is controlled to retract. Therefore, during the exhaust process, if the humidity value in the cooking cavity 211 is reduced to meet the cooking needs and there is no need to open the door at present, the door 3 is controlled to close to meet the subsequent cooking needs and ensure the continuity of cooking.

[0112] Furthermore, the control method further includes: when the door 3 is pushed open due to meeting the second preset exhaust condition, if the duration of the door 3 being pushed open is greater than or equal to the preset duration and the preset door opening condition is not met at present, the push rod 11 is controlled to retract, thereby avoiding the problem of dust or other foreign matter entering the cooking cavity 211 due to the door 3 being opened for a long time.

[0113] Embodiment 3

[0114] This embodiment provides a control method for a cooking device, and the control method provided in this embodiment is basically the same as that in the second embodiment, with only some differences in settings. This embodiment will not repeat the same contents as those in the second embodiment.

[0115] In this embodiment, the control method includes: when the door 3 is pushed open due to meeting the preset exhaust condition, if the preset door opening condition is not currently met and the humidity value in the cooking cavity 211 is equal to or less than the second preset humidity value, the push rod 11 is controlled to retract.

[0116] That is, in this embodiment, no matter what the preset exhaust condition is, if the humidity value of the inner tank 21 is detected to be reduced to the second preset humidity value during the door opening exhaust process, it indicates that there is no need for exhaust, and if the preset door opening condition is not met at present, the door 3 can be closed. In this way, the control logic of closing the door 3 during the exhaust process can be simplified, and the control cost can be reduced.

[0117] The preset exhaust conditions can be set with reference to the second embodiment, that is, the preset exhaust conditions include a first preset exhaust condition and a second preset exhaust condition. No matter whether the door 3 is opened due to the first preset exhaust condition or the second preset exhaust condition, it is because the humidity value in the cooking cavity 211 needs to be lowered. Therefore, when the humidity value in the cooking cavity 211 is reduced to the second preset humidity value, it indicates that the exhaust process can be ended.

[0118] It can be understood that the second preset humidity value may be different according to the different preset exhaust conditions that cause the door 3 to be pushed open. When the door 3 is pushed open due to the first preset exhaust condition, the second preset humidity value is less than or equal to the first preset humidity value; when the door 3 is pushed open due to the second preset exhaust condition, the second preset humidity value may be different from the value set when the door 3 is pushed open due to the first preset exhaust condition.

[0119] In other embodiments, no matter the door 3 is pushed open because the first preset exhaust condition is met or the second preset exhaust condition is met, the second preset humidity value is the same, and the second preset humidity value is less than or equal to the first preset humidity value.

[0120] Embodiment 4

[0121] This embodiment provides a control method for a cooking device, and the control method provided in this embodiment is a further improvement based on the control method provided in the second embodiment. This embodiment will not repeat the same contents as those in the second embodiment.

[0122] In this embodiment, the controller of the cooking device has built-in different first preset angles corresponding to different humidity values ​​of the cooking cavity 211, and the preset exhaust conditions include first preset exhaust conditions, which include the humidity value in the cooking cavity 211 being greater than or equal to the first preset humidity value.

[0123] The control method further includes: during the cooking process, detecting the humidity value in the cooking cavity 211 in real time, and when the detected humidity value is greater than a first preset humidity value, determining a first preset angle based on the detected humidity value.

[0124] In this way, the first preset angle can be selected and controlled through the detected humidity value, thereby controlling the opening angle of the door 3 and further controlling the exhaust efficiency, thereby avoiding the problem that the humidity value in the cooking cavity 211 quickly decreases to below the cooking requirement when the difference between the detected humidity value and the first preset humidity value is small and the first preset angle is large. It can also ensure rapid dehumidification when the difference between the detected humidity value and the first preset humidity value is large, thereby improving the humidity control accuracy.

[0125] The control method provided in this embodiment can also be used as a further improvement of the control method in the third embodiment.

[0126] Embodiment 5

[0127] This embodiment provides a control method for a cooking device, and the control method provided in this embodiment is a further improvement based on the control method provided in the second embodiment. This embodiment will not repeat the same contents as those in the second embodiment.

[0128] In this embodiment, the controller of the cooking device has built-in different first preset angles corresponding to different remaining cooking times, and the preset exhaust conditions include second preset exhaust conditions, and the second preset exhaust conditions include: the remaining cooking time is less than or equal to the preset time.

[0129] The control method includes: determining a first preset angle based on a current remaining cooking time.

[0130] During the cooking process, after the user selects a cooking mode, the cooking time is basically determined. However, in some cooking scenarios, the user may adjust the cooking time during the cooking process, so that the remaining time after the user's adjustment is less than the preset time. As a result, if the exhaust is opened according to a fixed first preset angle, the exhaust speed may be slow, affecting the user's door opening experience. Therefore, in this embodiment, when the remaining cooking time is less than the preset time, the first preset angle is determined based on the current remaining cooking time, so as to better meet the demand for rapid exhaust.

[0131] It can be understood that in other embodiments, when the door 3 needs to be opened to a first preset angle due to meeting the second exhaust condition, the first preset angle can be a fixed value, and the first preset angle is close to the critical opening angle to achieve rapid exhaust after cooking is about to end.

[0132] The control method provided in this embodiment can also be used as a further improvement of the control methods provided in Embodiment 3 and Embodiment 4.

[0133] Embodiment 6

[0134] This embodiment provides a control method for a cooking device, and the control method provided in this embodiment is a further improvement of the control method provided in the second embodiment. This embodiment will not repeat the same contents as those in the second embodiment.

[0135] In this embodiment, the cooking device has multiple cooking modes built in, and the controller of the cooking device has different first preset angles corresponding to the different cooking modes built in.

[0136] The control method also includes:

[0137] Before cooking begins, identify the cooking mode;

[0138] According to the cooking mode, a first preset angle is determined.

[0139] When the cooking device has multiple cooking modes, each cooking mode has different requirements for exhaust gas.

[0140] For example, in the steaming mode, saturated steam is basically used to steam the food, so that during the cooking process, there is basically no need to exhaust due to excessive humidity in the inner pot 21. Because the amount of steam in the inner pot 21 is large after cooking in the steaming mode, the air should be exhausted quickly when cooking is about to end to prevent steam from blowing in the face. Therefore, in the steaming mode, the exhaust condition is basically the second exhaust condition. At this time, the first preset angle can be set to a relatively large angle to meet the need for quick exhaust.

[0141] In baking mode or steaming mode, the humidity and temperature requirements in the cooking cavity 211 are relatively high. In order to make the food taste better, it is necessary to control the temperature and humidity in the cooking cavity 211. At this time, if exhaust is performed because the first preset exhaust condition is met, the first preset angle can be set to a relatively small angle or the first preset angle can be selected according to the difference between the current humidity value in the cooking cavity 211 and the first preset humidity value to better meet the humidity control requirements.

[0142] In the fruit and vegetable drying mode, the food in the cooking cavity 211 gradually matures and dries as the cooking time increases, and the humidity value in the inner pot 21 also slowly rises. When the humidity value in the inner pot 21 is greater than the preset humidity value, it is determined that the first preset exhaust condition is met, and the door 3 needs to be opened to a first preset angle to quickly exhaust the internal moisture and maintain the drying process. When the first preset angle is too large, it may cause the temperature in the cooking cavity 211 to drop and affect the drying temperature. Therefore, the first preset angle can be set by comprehensively considering the drying temperature and exhaust requirements.

[0143] Therefore, the control method provided in this embodiment determines the first preset angle through the cooking mode, which can better meet the exhaust requirements under different cooking modes, and simplify the control logic while improving the control accuracy.
