In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

The term "two or more" includes two or more cases.
[0034] The following is in conjunction with the appendix Figure 1-9 This application describes a cooking apparatus 100 according to some embodiments.
[0035] like Figure 1 As shown, the cooking device 100 according to an embodiment of this application includes: a pot body 10 and a food carrier 30.
[0036] like Figure 1 As shown, a cooking cavity 11 is formed inside the pot body 10, and at least a portion of the food carrier 30 is located inside the cooking cavity 11. In this way, food can be placed inside the food carrier 30 to achieve steaming or cooking.
[0037] In some implementations, the food carrier 30 can be a steamer, a steaming tray, or other structure capable of steaming or cooking food.
[0038] For example, when the food carrier 30 is a steamer, the steamer has multiple through holes. The steamer is located inside the cooking cavity 11 and is spaced apart from the bottom wall of the cooking cavity 11. When steaming food, water can be placed inside the cooking cavity 11, and the food can be placed inside the steamer. The steamer is spaced apart from the water surface. Then, the water in the cooking cavity 11 is heated so that the steam heats the food, thereby enabling the cooking device 100 to have a steaming function.
[0039] like Figure 2 As shown, the cooking device 100 also includes a stirring element 20, which is rotatably mounted inside the cooking cavity 11. Thus, food can be placed inside the cooking cavity 11, and the stirring element 20 can be used to stir and break up the food, thereby enabling the cooking device 100 to have a stirring function.
[0040] like Figure 2 and Figure 3 As shown, the food carrier 30 is connected to the stirring member 20. When the stirring member 20 rotates, it drives the food carrier 30 to move along the extension direction of the rotation axis of the stirring member 20.
[0041] It is understandable that when the mixing component 20 rotates along the rotation axis, the mixing component 20 will drive the food carrier 30 to rise or fall in the axial direction of the mixing component 20, so that the rotation of the mixing component 20 and the lifting and lowering movement of the food carrier 30 can be realized synchronously. In this way, the lifting and lowering movement of the food mixing component 20 can be realized through the rotation of the mixing component 20, so that the lifting and lowering movement of the food carrier 30 does not need to be manually controlled.
[0042] Meanwhile, the lifting and lowering motion of the food mixing component 20 and the rotation of the mixing component 20 can utilize the same drive structure, which saves on the setting of the drive structure. For example, when the food carrier 30 is required, it is only necessary to connect the food carrier 30 to the mixing component 20, without the need to set a separate drive structure for the lifting and lowering motion of the food mixing component 20, which saves on the setting of at least one drive structure, thereby reducing the difficulty and cost of setting up.
[0043] In particular, in this embodiment, the stirring member 20 and the food carrier 30 are connected, and the stirring member 20 can drive the food carrier 30 to move along the extension direction of the rotation axis of the stirring member 20 when it rotates. This facilitates the simultaneous use of the food carrier 30 in scenarios such as stirring the bottom of the pot and lifting and lowering the food carrier 30 to drain water (or oil), thus meeting the user's needs.
[0044] For example, in some usage scenarios, the food carrier 30 is a steamer, where edible ingredients are placed inside the steamer and water is placed inside the cooking cavity 11. At this time, the rotation of the stirring element 20 can cause the food carrier 30 to descend along the axis of the stirring element 20 so that the ingredients and water can come into full contact. Alternatively, the rotation of the stirring element 20 can cause the food carrier 30 to rise along the axis of the stirring element 20 so that the ingredients and water can be separated, thereby realizing the draining function of the cooking device 100.
[0045] Alternatively, in other usage scenarios, the food carrier 30 can be a steamer. In this case, the ingredients and the liquid used for cooking the ingredients can be placed in the cooking cavity 11. The liquid used for cooking the ingredients can be, but is not limited to, water. Seasonings or seasoning packets can be placed in the steamer. During actual cooking, the ingredients and liquid in the cooking cavity 11 can be stirred by the stirring member 20 to ensure the cooking effect. At the same time, the rotation of the stirring member 20 can drive the food carrier 30 to move axially. For example, when the stirring member 20 rotates clockwise, the food carrier 30 moves upward along the axial direction of the stirring member 20. In this way, the auxiliary ingredients in the food carrier 30 can be separated from the soup in the cooking cavity 11, so that there is no need to manually retrieve or sort the seasonings or seasoning packets, thereby improving the convenience of the cooking equipment 100.
[0046] According to the embodiments of the present application, the stirring element 20 can drive the food carrier 30 to move along the extension direction of the rotation axis of the stirring element 20 when it rotates. In this way, the rotation of the stirring element 20 and the lifting and lowering movement of the food carrier 30 can be realized synchronously, so that the stirring element 20 and the food carrier 30 do not need to be adjusted independently, thereby reducing the difficulty of using the cooking device 100 and facilitating the simultaneous use of multiple functions such as stirring the bottom of the pot and lifting and lowering the food carrier 30 to drain water (or oil), thus meeting the user's needs.
[0047] In some embodiments, such as Figure 3 As shown, one of the stirring component 20 and the food carrier 30 is provided with a mating protrusion 22 and the other is provided with a mating groove 31. The mating protrusion 22 is inserted into the mating groove 31 and is threadedly engaged with the mating groove 31.
[0048] For example Figure 3 As shown, the food carrier 30 is provided with a mating protrusion 22, such as Figure 4 As shown, the food carrier 30 is provided with a mating groove 31, and the mating protrusion 22 is inserted into the mating groove 31 and threadedly engaged with the mating groove 31. It can be understood that the food carrier 30 and the inner wall of the cooking cavity 11 are in a maximum engagement in the rotation direction of the stirring member 20, and the inner wall of the mating groove 31 is provided with an internal thread, and the outer peripheral wall of the mating protrusion 22 is provided with an external thread, with the internal thread and the external thread engaging.
[0049] When the mixing element 20 rotates, the mating protrusion 22 rotates relative to the mating groove 31. Since the food carrier 30 and the inner wall of the cooking cavity 11 are in upper limit mating in the rotation direction of the mixing element 20, the food carrier 30 can only move up and down relative to the mating protrusion 22. Thus, when the mixing element 20 rotates, it can drive the food carrier 30 to move along the extension direction of the rotation axis of the mixing element 20. In this way, the rotation of the mixing element 20 and the up and down movement of the food carrier 30 can be realized synchronously. Therefore, the mixing element 20 and the food carrier 30 do not need to be adjusted independently, which reduces the difficulty of using the cooking equipment 100. Moreover, the threaded mating method is relatively simple, which helps to reduce the installation cost and installation difficulty.
[0050] In some embodiments, such as Figure 3 , Figures 5-7 As shown, the stirring member 20 includes a stirring blade portion 21 and a mating protrusion 22. The stirring blade portion 21 is connected to the outer peripheral wall of the mating protrusion 22. In the extension direction of the rotation axis of the stirring member 20, the mating protrusion 22 protrudes from the stirring blade portion 21.
[0051] Therefore, by setting the mating protrusion 22 to protrude from the stirring blade portion 21 in the extension direction of the rotation axis of the stirring member 20, it is possible to realize the insertion of the mating protrusion 22 and the mating groove 31. In particular, when the mating protrusion 22 and the mating groove 31 are inserted, the risk of interference between the food carrier 30 and the stirring blade portion 21 is reduced, thereby protecting the stirring blade portion 21 and the food carrier 30.
[0052] In some embodiments, such as Figure 6 and Figure 7 As shown, the mixing component 20 also includes a connecting portion 23, which is connected between the mating protrusion 22 and the mixing blade portion 21, and the connecting portion 23 is used to limit the food carrier 30 in the extension direction of the rotation axis of the mixing component 20.
[0053] Understandably, when the protrusion 22 is inserted into the groove 31, the connecting part 23 and the food carrier 30 can be limited and matched in the extension direction of the rotation axis of the stirring member 20 to reduce the risk of interference between the food carrier 30 and the stirring blade 21, thereby protecting the stirring blade 21 and the food carrier 30.
[0054] In some embodiments, such as Figure 3 As shown, the cross-sectional area of the connecting portion 23 gradually increases in the direction from the mating protrusion 22 to the stirring blade portion 21.
[0055] As a result, the radial dimension of the connecting part 23 gradually increases, thereby gradually enhancing the limiting ability of the connecting part 23 in the extension direction of the rotation axis of the stirring member 20. That is, as the opening of the limiting groove gradually increases, it can also achieve limiting cooperation with the food carrier 30 in the extension direction of the rotation axis of the stirring member 20, thereby improving the stability of the limiting cooperation between the two.
[0056] In some embodiments, such as Figure 3 As shown, in the direction from the mating protrusion 22 to the stirring blade 21, the cross-sectional area of the connecting part 23 increases in a stepped manner.
[0057] As a result, the radial dimension of the connecting part 23 increases in a stepwise manner, so that the limiting ability of the connecting part 23 in the extension direction of the rotation axis of the stirring member 20 is gradually enhanced. That is, as the opening of the limiting groove gradually increases, it can also achieve limiting cooperation with the food carrier 30 in the extension direction of the rotation axis of the stirring member 20, thereby improving the stability of the limiting cooperation between the two.
[0058] In some embodiments, such as Figure 3 As shown, the opening of the mating groove 31 is provided with a mating inclined surface 311, which is suitable for being fitted onto the connecting part 23. In the extension direction of the rotation axis of the stirring component 20, the length of the mating inclined surface 311 is less than the length of the connecting part 23.
[0059] Therefore, after the mating protrusion 22 is inserted into the mating groove 31, the end of the mating inclined surface 311 away from the mating groove 31 will not contact the connection between the connecting part 23 and the stirring blade part 21, thereby reducing the risk of interference between the food carrier 30 and the stirring blade part 21, and thus protecting the stirring blade part 21 and the food carrier 30.
[0060] In some embodiments, such as Figure 1 As shown, one of the pot body 10 and the food carrier 30 is provided with a slot 32 and the other is provided with a buckle 12. The buckle 12 and the slot 32 are engaged in a circumferential upper limit engagement with the stirring member 20 and a sliding engagement in the extension direction of the rotation axis of the stirring member 20.
[0061] It is understandable that when the mixing element 20 rotates, the mating protrusion 22 rotates relative to the mating groove 31. Since the food carrier 30 and the inner wall of the cooking cavity 11 are in a maximum engagement in the rotation direction of the mixing element 20, the food carrier 30 can only move up and down relative to the mating protrusion 22. This allows the mixing element 20 to drive the food carrier 30 to move along the extension direction of the rotation axis of the mixing element 20 while rotating. As a result, the rotation of the mixing element 20 and the up and down movement of the food carrier 30 can be achieved synchronously. Therefore, the mixing element 20 and the food carrier 30 do not need to be adjusted independently, which reduces the difficulty of using the cooking equipment 100. Moreover, the threaded engagement method is relatively simple, which helps to reduce the setup cost and setup difficulty.
[0062] Thus, by setting the buckle 12 and the slot 32, the food carrier 30 and the pot body 10 are slidably engaged in the direction of extension of the rotation axis of the stirring member 20, and the food carrier 30 and the pot body 10 are engaged in the circumferential upper limit engagement of the stirring member 20, which can prevent the food carrier 30 and the pot body 10 from rotating relative to each other.
[0063] In some embodiments, such as Figure 1 As shown, the buckle 12 is disposed on the inner wall of the cooking cavity 11, as... Figure 8 As shown, the card slot 32 is provided on the food carrier 30.
[0064] It is understandable that the cooking cavity 11 needs to maintain a certain degree of airtightness during cooking, while the food carrier 30 has relatively lower requirements for airtightness, especially when the food carrier 30 is a steamer, as it already has multiple ventilation holes. Therefore, in this embodiment, the buckle 12 is disposed on the inner wall of the cooking cavity 11, and the slot 32 is disposed on the food carrier 30, in order to reduce design difficulty and minimize the impact on the cooking effect.
[0065] In some embodiments, such as Figure 1As shown, the cooking device 100 also includes a drive unit 40, which is mounted on the pot body 10. The stirring element 20 is connected to the output shaft 41 of the drive unit 40. Along the axial direction of the output shaft 41, the food carrier 30 is located on the side of the stirring element 20 away from the drive unit 40. The drive unit 40 can be a drive motor, a stepper motor, etc., and is not limited here.
[0066] Therefore, by setting the drive member 40, the stirring member 20 can be driven to rotate. At this time, the axial direction of the output shaft 41 coincides with the rotation axis of the stirring member 20, and the food carrier 30 is located on the side of the stirring member 20 away from the drive member 40, so as to avoid interference between the food carrier 30 and the drive member 40 when the stirring member 20 rotates and drives the food carrier 30 to move in the axial direction of the output shaft 41.
[0067] In some embodiments, the drive member 40 is disposed on the bottom wall of the cooking cavity 11, with at least a portion of the output shaft 41 extending into the cooking cavity 11 to be connected to the stirring member 20. Since the drive member 40 is disposed on the bottom wall of the cooking cavity 11, the encroachment on the space inside the cooking cavity 11 can be minimized.
[0068] In some embodiments, such as Figure 3 and Figure 6 As shown, the stirring component 20 is provided with a insertion slot 24, and the output shaft 41 is inserted into the insertion slot 24.
[0069] This allows the output shaft 41 to be inserted into the insertion slot 24 to connect with the stirring component 20, thereby enhancing the connection stability between the output shaft 41 and the stirring component 20. The insertion connection method is relatively simple and helps to reduce design difficulty.
[0070] In some embodiments, the cross-section of the insertion slot 24 is triangular, quadrilateral or polygonal, and the portion of the output shaft 41 inserted into the insertion slot 24 is designed to conform to the shape of the cross-section of the insertion slot 24.
[0071] Therefore, after the output shaft 41 is inserted into the insertion slot 24, the output shaft 41 and the insertion slot 24 can be limited in the circumferential direction of the output shaft 41, thereby preventing relative rotation between the stirring component 20 and the output shaft 41, and thus enhancing the connection stability between the output shaft 41 and the stirring component 20.
[0072] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
