Description

Technical Field

[0001] The invention relates to the technical field of kitchen equipment, in particular to a cooking device. Background Art

[0002] Cooking devices such as ovens and cooking machines usually include a box with an inner cavity and an opening on one side, a door for opening or closing the opening on the box, and a cooking body for holding ingredients to be cooked. In actual use, users often open the door when adding ingredients or taking out cooked food, which requires the cooking body to be moved out of the box. Therefore, users often expect that the cooking body and the door can be linked in some way to meet their above needs.

[0003] The cooking devices currently on the market are mainly divided into the following types according to the way the door body moves relative to the box body: cooking devices with flip-type door opening and drawer-pull-type door opening structures. In order to realize the linkage between the cooking body and the door body, the flip-type door opening structure usually connects the door body and the cooking body through a series of relatively complex connecting rod mechanisms to realize the linkage between the two. When the cooking device is working, the internal temperature is high, and the complex connecting rod mechanism will cause a certain degree of inconvenience in manufacturing and assembly, and due to the complex structure, the reliability is poor. The drawer-pull-type door opening structure often directly connects the cooking body with the door body, so that when the door body is pulled out, the cooking body is taken out together. Although this form does not require a complex connecting rod mechanism to realize the linkage between the door body and the cooking body, the drawer-type door opening method requires the user to cross the door body and perform relevant operations on the cooking body from above. When the cooking device is embedded at a high position, the user's operation is relatively inconvenient. Summary of the invention

[0004] Based on this, it is necessary to provide a cooking device that can address the above problems, and the cooking device can achieve the linkage between the door body and the cooking body, and the operation is relatively convenient.

[0005] A cooking device, comprising:

[0006] A box body, wherein the inner cavity of the box body is formed with an opening on one side of the box body;

[0007] A door body, one end of which is rotatably connected to the box body and is used to open or close the opening;

[0008] A cooking body, slidably disposed in the inner cavity;

[0009] A linkage mechanism, the linkage mechanism includes a traction rope, a pulley and a reset member, the traction rope is connected between the door body and the cooking body, and crosses the pulley arranged in the inner cavity, when the door body is flipped relative to the box body to open the opening, the traction rope can pull the cooking body out of the box body as the door body rotates, and the reset member is arranged in the inner cavity and is used to pull the cooking body toward the inner cavity.

[0010] With such a configuration, one end of the door body is rotatably connected to the box body. Therefore, when it is necessary to perform relevant operations on the cooking body in the inner cavity, the door body can be flipped open, and the user does not need to cross the door body to perform relevant operations on the cooking body. At the same time, the traction rope in the linkage mechanism crosses the pulley in the inner cavity and is directly or indirectly connected to the door body and the cooking body respectively. When the door body is flipped open, the traction rope can synchronously pull the cooking body in the inner cavity out, and when the door body is closed, the reset member pulls the cooking body back into the inner cavity. Compared with the use of a complex connecting rod mechanism to realize the linkage between the door body and the cooking body, the linkage mechanism formed by the fixed pulley principle has a simpler structure, and the pulley, traction rope and other structural parts can also be arranged more flexibly in the box body.

[0011] In one embodiment, the cooking device further includes a linkage selection component, which includes: a linkage selection pulley, which is arranged on the door body; and a locking pin, which can move relative to the linkage selection pulley so that the linkage selection pulley has a locked state and an unlocked state, in which the linkage selection pulley is fixed relative to the door body, and at least a portion of the traction rope is wound around the linkage selection pulley; in the unlocked state, the linkage selection pulley can rotate relative to the door body, thereby releasing at least a portion of the traction rope wound around the linkage selection pulley.

[0012] With such a configuration, in some cooking scenarios, the user does not want the cooking body to always be linked to the door body. For example, when putting ingredients into the cooking body after preheating the cooking body, completely taking the cooking body out of the box will usually cause the preheating temperature of the cooking body to be greatly affected. In this embodiment, the linkage relationship between the door body and the cooking body can be disconnected in time through the linkage selection component: when the user wants the cooking body to be completely pulled out as the door body is flipped open, the linkage selection pulley is switched to a locked state through the locking pin. At this time, the linkage selection pulley is fixed relative to the door body, and the traction rope can normally pull the cooking body out as the door body is flipped open; and when the user wants the cooking body to be only partially moved out instead of completely moved out of the inner cavity, the linkage selection pulley can be switched to an unlocked state at an appropriate time through the movement of the locking pin relative to the linkage selection pulley. In this unlocked state, the linkage selection pulley can rotate freely relative to the door body, and the traction rope wound on the linkage selection pulley is released due to the rotation of the linkage selection pulley, thereby failing to apply a pulling force to the cooking body.

[0013] In one of the embodiments, the linkage selection assembly further includes an elastic member, and in the unlocked state, the elastic force of the elastic member can drive the linkage selection pulley to rotate to reel in the traction rope.

[0014] In this way, when the linkage selection pulley is in an unlocked state, the rotation of the door body will cause the traction rope wound on the linkage selection pulley to be at least partially released, thereby adapting to the change in the distance between the door body and the cooking body when the door body is further flipped open, and avoiding pulling the traction rope and causing the cooking body to be further pulled out. When the door is closed in this state, the distance between it and the cooking body becomes shorter due to the reverse rotation of the door body. At this time, the elastic force applied to the linkage selection pulley by the elastic member drives the linkage selection pulley to rotate, which can prevent the traction rope from being rewound around the linkage selection pulley, thereby preventing the traction rope from being in a loose state.

[0015] In one of the embodiments, the linkage selection assembly further includes a driving member for driving the locking pin to move relative to the linkage selection pulley.

[0016] With such arrangement, the locking pin is driven by the driving member to move, so that the switching of the working state of the linkage selection pulley can be realized by electronic control.

[0017] In one of the embodiments, the linkage selection assembly further includes a lever connected to the motion output end of the driving member;

[0018] The locking pin is provided with a linkage portion that can be connected and matched with the shifting rod. When the driving member drives the shifting rod to rotate, the shifting rod can drive the locking pin to approach or move away from the linkage selection pulley through the linkage portion.

[0019] With such arrangement, the cooperation between the lever and the linkage portion enables the drive member to be flexibly arranged in a position according to needs.

[0020] In one of the embodiments, the cooking device further includes a controller and an angle detection device for detecting the rotation angle of the door body, and the controller can control the driving member according to the detection result of the angle detection device.

[0021] With such a configuration, during some cooking processes, the user wishes to completely flip the door open, but wishes to move the cooking body only partially out of the box. At this time, the controller can detect the angle of rotation of the door according to the angle detection device, so that when the door rotates to a certain angle, the locking pin is driven to move through the driving member to change the state of the linkage selection pulley.

[0022] In one embodiment, the cooking device further comprises a memory, wherein at least one preset cooking program is stored in the memory, and during the execution of the cooking program, the controller can control the driving member according to the execution progress.

[0023] With this arrangement, the controller controls the drive member according to the execution progress of the preset cooking program, thereby making the entire cooking process more automated.

[0024] In one embodiment, the lower end of the door body is rotatably connected to the box body; the pulley includes a first pulley and a second pulley, wherein: the first pulley is set corresponding to the sliding path of the cooking body so that the direction of the pulling force applied by the traction rope to the cooking body is parallel to the sliding direction of the cooking body; the second pulley is set corresponding to the height of the connection between the traction rope and the door body.

[0025] In this way, the arrangement of the first pulley and the second pulley allows the force of the user flipping open the door to be better converted into the force of pulling the cooking body to move, and the arrangement of the two pulleys also allows the traction rope to be arranged more regularly in the inner cavity of the box.

[0026] In one embodiment, the wrap angle of the traction rope on the second pulley is greater than 180 degrees.

[0027] With such arrangement, the wrap angle between the traction rope and the second pulley is greater than 180 degrees, so that the second pulley can provide directional guidance for the traction rope more stably, ensuring the movement stability of the cooking body in linkage with the flipping of the door body.

[0028] In one embodiment, the cooking device also includes a slide rail assembly for guiding the sliding of the cooking body, and the slide rail assembly includes an inner slide rail fixed on both sides of the sliding direction of the cooking body, and an outer slide rail arranged in the inner cavity and slidingly matched with the inner slide rail.

[0029] With such arrangement, the cooperation of the inner and outer slide rails can make the cooking body slide more smoothly and stably.

[0030] In one embodiment, the reset member is configured such that one end is connected to a side wall of the box body opposite to the opening, and the other end is connected to the inner slide rail or a spring of the cooking body.

[0031] With such arrangement, the spring is directly used as the reset member, which can simplify the structure of the overall linkage mechanism.

[0032] In one embodiment, the linkage mechanism is provided in two groups, and the two groups of linkage mechanisms are respectively provided on both sides of the sliding direction of the cooking body.

[0033] In this way, the two sets of linkage mechanism chalks are not arranged on both sides of the sliding direction of the cooking body, which can balance the forces on both sides of the cooking body and improve its sliding stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] See also Figure 1 and Figure 2 As shown in Figure 1 FIG. 1 shows a schematic structural diagram of a cooking device in an embodiment of the present invention. Figure 2 Another state of the cooking device in this embodiment is shown in FIG. One embodiment of the present invention provides a cooking device, comprising a box body 1, a door body 2, a cooking body (not shown in the figure), and a linkage mechanism 3. The inner cavity of the box body 1 is formed with an opening on one side of the box body 1, and one end side of the door body 2 is rotatably connected to the side of the box body 1, so that the door body 2 can open or close the opening by rotating relative to the box body 1.

[0057] like Figure 2 As shown in the figure, the lower end side of the box body 1 is connected to the lower end side of the door body 2 by a hinge 22, thereby realizing the rotational connection between the door body 2 and the box body 1. In other embodiments, the two can also be rotationally connected by other similar forms.

[0058] The cooking body can be slidably arranged in the inner cavity of the box body 1. Figures 9 to 11 As shown in , the cooking body can be a grill pan 7 as shown. Figure 12 to Figure 14 As shown in , the cooking body can also be the heating element 71 and the cooking pot body 72 shown in the figure, wherein the heating element 71 heats the cooking pot body 72 and the food therein. In other embodiments, the cooking body can also be in other forms, such as just a bracket.

[0059] The linkage mechanism 3 is used to establish a linkage relationship between the door body 2 and the cooking body. It includes a pulley arranged in the inner cavity of the box body 1, a traction rope 31 connected between the door body 2 and the cooking body, and a reset member 32. Among them: the traction rope 31 and the pulley constitute a fixed pulley mechanism, the traction rope 31 pulls the cooking body to slide out of the box body 1 with the force of flipping the door body 2, and the pulley is used to change the direction of the front pulling force of the traction rope 31. It can be understood that the traction rope 31 can be directly connected to the door body 2 and the cooking body, or it can form an indirect connection relationship with them through some intermediate connecting parts. The traction rope 31 is connected between the two mainly to establish a linkage and coordination relationship between the two. For example, in some embodiments, the traction rope 31 is connected to a structure such as a sliding device that can be detachably arranged on the cooking body.

[0060] The reset member 32 is disposed in the inner cavity of the housing 1 and is used to pull the cooking body toward the inner cavity. Figure 1 In the embodiment shown, the reset member 32 is configured as a spring, one end of which is connected to the inner wall of the housing 1 opposite to the opening, and the other end is connected to the cooking body. The reset member 32 is used to bring the cooking body back into the housing 1 in the reverse direction when the door 2 is rotated back to close the opening. In other embodiments, the reset member 32 can also be implemented in other forms. For example, the reset member 32 can be configured as an elastic winding device fixed to the inner wall of the housing 1. The elastic winding device can automatically wind up the traction rope 31 using an elastic member such as a coil spring, so as to bring the cooking body back into the housing 1 through the traction rope 31.

[0061] Combination Figure 2 As shown in the mark in , the resultant force acting on the door body 2 at the hinge 22 is F2, and its value is equal to the gravity exerted on the door body 2, the pulling force exerted on it by the traction rope 31 and other external forces. F2 is opposite to the opening direction of the door body 2, so as to keep the door body 2 in the open state. Furthermore, in order to ensure that the cooking body will not be pulled back into the box body 1 by the reset member 32 when the door body 2 is open, the maximum value of F2 should be greater than the pulling force F1 of the reset member 32, that is, the force keeping the door body 2 in the open state is greater than the reset force of the reset member 32.

[0062] In the related prior art, the door body opening methods include flip opening and closing and pull-out opening and closing. Among them: when realizing the linkage between the cooking body and the door body, the pull-out opening and closing method can simply connect the surface of the door body facing the inner side of the box directly to the cooking body, forming a drawer-like structure. If the flip opening and closing method hopes to link the door body with the cooking body, it is usually necessary to connect the door body and the cooking body through a more complicated connecting rod mechanism.

[0063] For cooking devices with a box body on the outside, such as steam ovens, many users will choose embedded installation in order to save kitchen space and beautify the kitchen layout. When the cooking device is embedded at a high height, the drawer-type linkage structure requires the user to cross the door body and perform related operations on the cooking body from above, which is inconvenient. Therefore, the flip-type opening and closing method has certain advantages. However, complex connecting rod mechanisms often affect the entire body, and there are many constraints in structural design. For example, in order to make the opening and closing angle of the door body and the distance the cooking body is pulled out meet a certain proportional relationship, it is usually necessary to limit the length, connection relationship, connection position and other factors of each rod in the connecting rod mechanism, which has a great impact on its layout in the inner cavity. Once other structural parts in the inner cavity interfere with it, it is usually difficult to solve the interference by changing the layout position or structure of the connecting rod mechanism, and other structural parts need to be designed to avoid it. In addition, the working temperature in the inner cavity can easily have an adverse effect on the hinge in the connecting rod mechanism.

[0064] Different from the solutions in the prior art, when the cooking device in this embodiment is embedded, since one end of the door body 2 is rotatably connected to the box body 1, the door body 2 is opened in a flipping manner, and the door body 2 can be flipped open to Figure 2 In the position shown, the door body 2 will hardly affect the user's operation of the cooking body. At the same time, the door body 2 and the cooking body are linked by a fixed pulley mechanism formed by the traction rope 31 and the pulley. Compared with the connecting rod mechanism, the structure of the linkage mechanism 3 is greatly simplified. To achieve a fixed ratio between the flipping and opening angle of the door body 2 and the sliding distance of the cooking body, it is only necessary to change the length of the traction rope 31 between the two, and the position of the pulley can be flexibly arranged in the box body 1.

[0065] In order to convert the force applied by the user to the door body 2 into the force for pulling the cooking body to move as much as possible, in the illustrated embodiment, the pulley includes a first pulley 33 and a second pulley 34, and the first pulley 33 is arranged corresponding to the sliding path of the cooking body so that the traction rope 31 can apply a pulling force to the cooking body along a direction roughly parallel to the sliding direction of the cooking body, and the second pulley 34 is arranged at the height where the traction rope 31 is connected to the door body 2, so as to maximize the use of the force applied by the user to the door body 2.

[0066] In one embodiment, in order to ensure the movement stability of the traction rope 31 as much as possible during the process of pulling the cooking body, the traction rope 31 is arranged according to Figure 1 and Figure 2 , that is, the traction rope 31 is wound around the second pulley 34 from the side close to the door body 2, and then wound around the second pulley 34 and connected to the corresponding position of the door body 2 in a substantially horizontal direction, so that the wrap angle α of the traction rope 31 on the second pulley 34 is greater than 180°. Figure 1 As shown in FIG. 1 , when the door body 2 is in a closed state, the wrap angle α is approximately 270°, and as shown in FIG. Figure 2 As shown in , when the door body 2 is flipped to a fully opened state, the wrap angle α of the traction rope 31 on the second pulley 34 exceeds 270°. The larger the wrap angle α, the more stable the relative position between the traction rope 31 and the second pulley 34, and the traction rope 31 can be reliably prevented from being disengaged from the second pulley 34 due to various reasons.

[0067] In order to make the movement of the cooking body relative to the box body 1 more stable, the cooking device may further include a slide rail assembly 4 for guiding the cooking body to slide, and the slide rail assembly 4 includes an inner slide rail 41 fixed on both sides of the sliding direction of the cooking body, and an outer slide rail 42 arranged in the inner cavity of the box body 1 and forming a sliding fit with the inner slide rail 41. In the embodiment provided with the slide rail assembly 4, the reset member 32 may also be selectively connected to the inner slide rail 41, thereby being "indirectly" connected to the cooking body. Similarly, the traction rope 31 may also be connected to the inner slide rail 41, thereby being "indirectly" connected to the cooking body.

[0068] The linkage mechanism 3 can be provided in one or two groups as required. When the linkage mechanism 3 is provided in two groups, the two groups of linkage mechanisms 3 are respectively provided on both sides of the sliding direction of the cooking body. It can be understood that the linkage mechanism 3 is provided on one side to provide sufficient pulling force to the cooking body to realize the linkage between the cooking body and the door body 2, while the linkage mechanism 3 is provided on both sides to make the forces on both sides of the cooking body more balanced, so as to ensure that it is stably pulled out of the box body 1.

[0069] Regardless of the aforementioned flip-type opening and closing method or the pull-out type opening and closing method, the linkage relationship between the door body and the cooking body cannot be changed, that is, when the cooking device is designed with a linkage relationship between the door body and the cooking body, the user only needs to open the door body later and the cooking body will be taken out. However, in actual cooking, there are some situations where the user wants to disconnect the linkage relationship between the door body and the cooking body. For example, the cooking body has just been preheated before the door body 2 is opened. When the door body 2 is opened to put food into the cooking body, the user usually hopes that the temperature of the cooking body is as unaffected as possible by the opening of the door body 2. Therefore, in this case, the more ideal linkage method is that the cooking body moves outward with the door body 2 for a certain distance to meet the needs of putting food, but do not move it out completely to avoid affecting the temperature. For the pull-out type opening and closing solution, in this case, the user can only manually control the distance that the door body is pulled open, which is inconvenient to operate, and the door body greatly affects the user's operation. As for the flip-type opening and closing solution, if the door body only flips a small angle, so that the cooking body moves outward for a certain distance and then stops, not only does the half-open and half-closed door body itself need to be manually fixed by the user, but the door body will also affect the user's action of putting in food.

[0070] To solve this problem, Figures 3 to 6In the illustrated embodiment, the cooking device further includes a linkage selection component 5, which enables the user to disconnect the linkage relationship between the door body 2 and the cooking body as needed, so that the door body 2 can be flipped to a fully open position, and the cooking body only moves out a certain distance. In practice, the user can choose to disconnect the linkage relationship between the door body 2 and the cooking body before the door body 2 is first rotated to a preset angle, and then make the two linked after the door body 2 is rotated to the preset angle, so that the further rotation of the door body 2 can appropriately pull the cooking body out a certain distance; or the user can also choose to make the cooking body linked with it when the door body 2 starts to rotate, and then disconnect the linkage relationship between the two after the door body 2 is rotated to the preset angle, so that the further rotation of the door body 2 will not drive the cooking body to move further outward. In both methods, the purpose of fully opening the door body but not completely moving the cooking body out of the cabinet 1 can be achieved.

[0071] The linkage selection assembly 5 includes a linkage selection pulley 51 and a locking pin 53, wherein: the linkage selection pulley 51 is arranged on the door body 2, and the locking pin 53 can move relative to the linkage selection pulley 51, so that the linkage selection pulley 51 has a locked state and an unlocked state. In the locked state, the locking pin 53 locks the rotation of the linkage selection pulley 51 relative to the door body 2, and the traction rope 31 is partially wound on the linkage selection pulley 51, so that the linkage selection pulley 51 is only connected to the traction rope 31 to the door body 2, and the flipping and opening of the door body 2 can normally drive the cooking body to move outward through the traction rope 31. In the unlocked state, the locking pin 53 releases the rotation restriction on the linkage selection pulley 51, and the linkage selection pulley 51 can rotate freely relative to the door body 2. In this way, when the door body 2 is opened, the linkage selection pulley 51 cannot pull the cooking body through the traction rope 31 because it can rotate freely. At this time, the part of the traction rope 31 wound around the linkage selection pulley 51 is released as the linkage selection pulley 51 rotates to adapt to the change in the distance between the door body 2 and the cooking body when the door body 2 is flipped open.

[0072] The cooking device in the above embodiment not only realizes the selection of whether the door body 2 and the cooking body are linked through the linkage selection component 5, but also when the door body 2 and the cooking body are disconnected from the linkage relationship, that is, after the linkage selection pulley 51 is switched to the unlocked state, the flipping process of the door body 2 no longer drives the cooking body, and thus the flipping process of the door body 2 is easier and more labor-saving.

[0073] Furthermore, the linkage selection assembly 5 may further include an elastic member 52, the elastic force of which can drive the linkage selection pulley 51 to rotate when the linkage selection pulley 51 is in the unlocked state, so that the traction rope 31 can be kept in a straight state. In some embodiments, the elastic member 52 is designed as a torsion spring, the elastic force of which can drive the linkage selection pulley 51 to rotate in one direction, so that the traction rope 31 can be wound onto the linkage selection pulley 51 as needed.

[0074] When the linkage selection pulley 51 is in the locked state, the elastic member 52 basically does not play a role. In the process of opening the door body 2, at a certain time, the linkage selection pulley 51 is switched to the unlocked state, and the action of further rotating the door body 2 may cause a part of the traction rope 31 wound on the linkage selection pulley 51 to be released. In this state, in the process of reversely rotating the door body 2, the elastic member 52 can drive the linkage selection pulley 51 to rotate, so that the released part of the traction rope 31 is rewound onto the linkage selection pulley 51 to prevent the traction rope 31 from being loosely connected between the door body 2 and the cooking body.

[0075] It is understood that after the traction rope 31 is rolled up to a certain extent, the user can switch the linkage selection pulley 51 to the locked state again, so that the traction rope 31 cannot be further rolled up. Alternatively, after the cooking body is brought back into the box body 1 by the reset member 32, the linkage selection pulley 51 can be switched to the locked state again, so that the loose traction rope 31 can be rolled up and kept in a straight state. This option is related to the timing of disconnecting the linkage relationship between the door body 2 and the cooking body as described above.

[0076] In one embodiment, the linkage selection pulley 51 and the elastic member 52 can be disposed on the handle 21 on the door body 2. Figure 4 As shown in the mark in, in the unlocked state, in order to prevent the pulling force of the elastic member 52 from further pulling out the cooking body, the equivalent pulling force F3 of the elastic member 52 acting on the traction rope 31 should be smaller than the elastic force F1 of the reset member 32. Since the elastic member 52 is only used to reel in the traction rope 31, its elastic force should not be too large, and it is sufficient to just realize the natural reeling of the traction rope 31, thereby preventing the elastic member 52 from pulling the reeling traction rope 31 to pull the cooking body out of the box 1.

[0077] Combination Figures 5 to 8 As shown in , in order to realize the electronically controlled switching of the working state of the linkage selection pulley 51, the linkage selection assembly 5 further includes a driving member 54, and the driving member 54 is used to drive the movement of the locking pin 53 relative to the linkage selection pulley 51. In order to flexibly arrange the position of the driving member 54, the linkage selection assembly 5 may further include a lever 55, one end of which is connected to the motion output end of the driving member 54, and the locking pin 53 is provided with a linkage part 531 that can cooperate with the other end of the lever 55. When the driving member 54 drives the lever 55 to rotate, the lever 55 cooperates with the linkage part 531 to drive the locking pin 53 to approach or move away from the linkage selection pulley 51.

[0078] It can be understood that in other embodiments, the linkage between the driving member 54 and the locking pin 53 can also be achieved with other transmission mechanisms. For example, a linear motor is directly selected as the driving member 54 and is directly connected to the locking pin 53, so that the linear motor can directly drive the locking pin 53 to translate closer to or away from the linkage selection pulley 51.

[0079] As mentioned above, in some cases, the user hopes that the linkage relationship between the cooking body and the door body 2 will be disconnected after the door body 2 is flipped open to a certain angle, or that the door body 2 will be linked with the cooking body only after it is flipped open to a certain angle. In order to facilitate the automatic control of this process, the cooking device also includes a controller, and an angle detection device 6 for detecting the rotation angle of the door body 2. The controller can control the operation of the drive member 54 according to the detection result of the angle detection device 6.

[0080] In addition, in order to facilitate users who are not good at cooking to cook normally through the cooking device, the cooking device can also include a memory, in which at least one preset cooking program is stored. During the execution of the cooking program, the controller can control the drive member 54 according to the execution progress.

[0081] The following is a flow chart of executing a cooking program pre-stored in a memory, which includes the following steps:

[0082] S1 displays recipes for the user to choose, wherein the recipes correspond one to one with the cooking programs pre-stored in the memory;

[0083] S2: After the user inputs the selection result (taking braised pork as an example), the cooking device reminds the user to put the ingredients into the cooking body in any appropriate way;

[0084] S3 The controller controls the driving member 54 to move, so that the locking pin 53 moves to the position of inserting the linkage selection pulley 51, so that the linkage selection pulley 51 switches to the locked state. At this time, the user opens the door body 2 to drive the cooking body to slide out of the box body 1, so that the user can put food into the cooking body;

[0085] S4 After the door 2 is closed, the cooking body is heated for a preset time, after which the cooking device reminds the user in any appropriate manner that the heating process is finished;

[0086] S5 The controller controls the driving member 54 to move, so that the locking pin 53 moves to the position of inserting the linkage selection pulley 51, so that the linkage selection pulley 51 switches to the locked state. At this time, the user opens the door 2 to drive the cooking body to slide out of the box 1. At this time, the user can take out the food in the cooking body, wash it, and then put it back into the cooking body, and add oil and appropriate spices to the cooking body.

[0087] S6 After the door 2 is closed, the cooking body is heated for a preset time to perform a stir-frying process, after which the cooking device reminds the user to add seasoning in any appropriate manner;

[0088] S7: The controller controls the driving member 54 to move, so that the locking pin 53 moves to a position where the linkage selection pulley 51 is withdrawn, so that the linkage selection pulley 51 is switched to an unlocked state. At this time, the user can flip and open the door body 2 alone.

[0089] S8 When the angle detection device 6 detects that the rotation angle of the door body 2 exceeds a preset angle (for example, 45°), the controller controls the driving member 54 to move according to the signal sent by the angle detection device 6, so that the locking pin 53 moves to a position where it is inserted into the linkage selection pulley 51, so that the linkage selection pulley 51 switches back to the locked state. At this time, when the user further flips the door body 2, the cooking body can be driven to slide out of the box body 1, for example, to Fig.14 In the state shown in , the user can heat the seasoning into the cooking body;

[0090] S9 When the door body 2 is closed, when the angle detection device 6 detects that the door body 2 has rotated more than 45 degrees, the controller controls the driving member 54 to move, so that the locking pin 53 moves to the position of exiting the linkage selection pulley 51, so that the linkage selection pulley 51 switches back to the unlocked state. As the door body 2 is closed, the elastic member 52 winds the traction rope 31 around the linkage selection pulley 51 to keep the traction rope 31 straight. After that, the cooking body is heated for a preset time to perform the stewing and juice collection process. After that, the cooking device reminds the user of the end of the cooking program in any appropriate way.

[0091] S10 The controller controls the driving member 54 to move, so that the locking pin 53 moves to the position of inserting the linkage selection pulley 51, so that the linkage selection pulley 51 switches to the locked state. At this time, the user opens the door body 2 to drive the cooking body to slide completely out of the box body 1, so that the user can take the food.
