Description

Technical Field

[0001] This utility model relates to the field of cooking machines, and more particularly to a pot lid and pot for a cooking machine and a cooking machine. Background Technology

[0002] When the cooking machine is in operation, the lid is closed over the opening of the pot. The water inside the pot is heated and turns into steam. When the steam cools on the surface of the lid, it condenses into water droplets. Some of these water droplets fall back into the pot, affecting the taste of the stir-fried food and causing contamination of the ingredients.

[0003] To address this, vents are typically installed on the lid to release steam from the pot, as seen in Chinese utility model patents ZL201921024978.6 (authorization announcement number CN210748815U) and ZL201721851851.2 (authorization announcement number CN208192907U). However, in slow-fry mode, the amount of steam produced is relatively small, allowing it to escape quickly from the vents with minimal water droplet backflow. In high-heat stir-fry mode, the higher power of the machine causes a rapid rise in pot temperature, generating a large amount of steam. This steam is difficult to escape quickly from the vents, causing significant condensation on the lid surface and resulting in a considerable amount of water droplets flowing back into the pot, affecting the taste of the cooked food. Some stir-fry machines employ a condensate drainage design to concentrate the condensate in a storage area, preventing backflow into the pot. However, this increases the complexity of the internal structure, raising manufacturing difficulty and production costs. Summary of the Invention

[0004] The first technical problem to be solved by this utility model is to provide a pot lid for a cooking machine that has a simple structure and can prevent condensation from forming on the inner surface of the pot lid, in contrast to the prior art.

[0005] The second technical problem to be solved by this utility model is to provide a cookware with the above-mentioned lid, in contrast to the prior art.

[0006] The third technical problem to be solved by this utility model is to provide a stir-fry machine with the above-mentioned cookware, in contrast to the prior art.

[0007] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a pot lid for a cooking machine, comprising a lid body, characterized in that the lid body comprises, from the inside to the outside, an inner lining layer, a heating layer, a heat insulation layer and an outer shell layer, wherein the heating layer is disposed on the inner surface of the inner lining layer, and the heat insulation layer is disposed on the inner surface of the outer shell layer.

[0008] Furthermore, the insulation layer is a vacuum layer. By using a vacuum layer to prevent heat transfer to the outer surface of the outer shell, the insulation effect can be guaranteed, and there is no need to add additional insulation materials, which helps to reduce the production cost of the pot lid.

[0009] Furthermore, the heating layer is a heating film coated on the inner surface of the liner or a heating plate stacked on the inner surface of the liner. Designing the heating layer as a heating film or a heating plate simplifies the internal structure of the pot lid and allows for sufficient heating of the liner.

[0010] Furthermore, the inner lining, heating layer, insulation layer, and outer shell layer are continuously arranged from the inside out. The heating layer is a heating plate, and the insulation layer is a vacuum layer formed by the heating plate and the inner and outer perimeter of the outer shell layer. This simplifies the internal structure of the lid. Simultaneously, while ensuring the insulation effect of the insulation layer on the heat generated by the heating layer, an insulation layer can be easily constructed between the heating layer and the outer shell layer without the need for additional insulation material.

[0011] Furthermore, at least one of the inner surface of the inner liner and the inner surface of the outer shell is provided with a groove, and the two are joined together to form a mounting cavity. The heating plate is housed on one side of the mounting cavity, while the heat insulation layer is formed on the other side of the mounting cavity. By forming a mounting cavity between the inner liner and the outer shell, a stable installation of the heating layer can be achieved, and a better heat insulation layer can be formed between the heating layer and the outer shell.

[0012] Furthermore, the inner surface of the outer shell layer is flat, and its outer periphery is recessed with an annular groove. The inner surface of the inner liner layer is provided with a circular groove, and the groove wall extends outward in the circumferential direction to form a convex ring. This convex ring is engaged in the annular groove, and the heating plate is accommodated in the annular groove. The thickness of the heating plate is less than the depth of the annular groove, so as to form the heat insulation layer between the inner surface of the heating layer and the outer shell layer. The snap-fit ​​connection between the inner liner layer and the outer shell layer makes the mounting cavity structure formed between them more stable, thereby better ensuring the stable installation of the heating plate and the stability of the heat insulation layer structure.

[0013] Furthermore, a sealing ring is provided around the outer periphery of the lid. When the lid is closed over the opening of the pot, the sealing ring is circumferentially sandwiched between the outer periphery of the lid and the rim of the pot opening. By providing the sealing ring, water vapor can be prevented from escaping through the gap between the two during cooking and condensing into condensate. Condensate flowing everywhere would affect the user experience.

[0014] Furthermore, a handle is integrally formed on the outer surface of the outer shell layer, making it convenient to lift the pot lid.

[0015] Furthermore, it also includes a stirrer, which includes stirring claws disposed inside the lid body for stirring food and a drive structure for driving the stirring claws to rotate. The drive structure includes a drive motor that passes through a central hole in the lid body along the axial direction.

[0016] It also includes a connecting arm mounted on the outer surface of the outer shell layer. One end of the connecting arm covers the central hole and has a motor mount for mounting the drive motor, while the other end is a hinge seat for hinged to a mounting base fixed on the operating table. In operation, the rotation of the stirring claw enables automatic stirring and stir-frying of food. The connecting arm allows the lid to be rotated on the operating table, facilitating its placement on or removal from the opening of the pot. It also ensures a stable mounting of the drive motor on the lid.

[0017] Furthermore, the heating plate is provided with a positive electrode plate and a negative electrode plate, each electrode plate having a contact post. The connecting arm has corresponding insertion holes for each contact post, and each insertion hole has a contact point. Each contact post is inserted into its corresponding insertion hole and electrically connected to the contact point of that hole. This ensures normal power supply to the heating plate, guaranteeing its heating function.

[0018] The technical solution adopted to further solve the second technical problem mentioned above is: a cookware, including a pot body, characterized in that it also includes a pot lid for a stir-fry machine as described above.

[0019] The technical solution adopted to further solve the third technical problem mentioned above is: a cooking machine, characterized in that it includes the pot as described above.

[0020] Compared with the prior art, the advantages of this utility model are as follows: the cover body includes an inner lining layer, a heating layer, a heat insulation layer and an outer shell layer from the inside to the outside, with a simple structure. The heating layer is set on the inner surface of the inner lining layer, so that the inner lining layer is heated by the heating layer, and water vapor is prevented from condensing on the outer surface of the inner lining layer. At the same time, the heat insulation layer is set on the inner surface of the outer shell layer, so that heat is prevented from being transferred to the outer surface of the outer shell layer. On the one hand, it can prevent heat loss of the heating layer, so that the heat generated by the heating layer can fully heat the inner lining layer, and on the other hand, it can prevent burns to the user.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] like Figure 1 As shown, a cooking machine includes a worktable 5 and a pot set on the worktable 5, wherein the pot includes a pot body 7 and a lid 1 for covering the opening of the pot body 7. In this embodiment, specifically, the worktable 5 is the panel of a gas stove 8, and the gas stove 8 is embedded in a cabinet 9.

[0029] Furthermore, such as Figures 2-5 As shown, the pot lid 1 includes a lid body 10, which includes, from the inside out, an inner lining layer 11, a heating layer 12, a heat insulation layer 13, and an outer shell layer 14. The heating layer 12 is disposed on the inner surface of the inner lining layer 11, and the heat insulation layer 13 is disposed on the inner surface of the outer shell layer 14.

[0030] As can be seen from the above, in this utility model, the cover 10 includes an inner lining layer 11, a heating layer 12, a heat insulation layer 13, and an outer shell layer 14 from the inside to the outside. The heating layer 12 is disposed on the inner surface of the inner lining layer 11, so that the inner lining layer 11 is heated by the heating layer 12, and water vapor is prevented from condensing on the outer surface of the inner lining layer 11. At the same time, the heat insulation layer 13 is disposed on the inner surface of the outer shell layer 14, so that heat is prevented from being transferred to the outer surface of the outer shell layer 14. On the one hand, the heat loss of the heating layer 12 can be avoided, so that the heat generated by the heating layer 12 can fully heat the inner lining layer 11. On the other hand, it can prevent the user from being burned.

[0031] Preferably, the heat insulation layer 13 is a vacuum layer. By using a vacuum layer to prevent heat transfer to the outer surface of the outer shell layer 14, the heat insulation effect is ensured, and the elimination of the need for additional heat insulation material reduces the production cost of the pot lid 1. Preferably, the heating layer 12 is a heating film coated on the inner surface of the inner lining layer 11 or a heating plate stacked on the inner surface of the inner lining layer 11. Designing the heating layer 12 as a heating film or heating plate simplifies the internal structure of the pot lid 1, and allows for sufficient heating of the inner lining layer 11.

[0032] Specifically, such as Figure 3 As shown, the inner lining layer 11, heating layer 12, heat insulation layer 13, and outer shell layer 14 are continuously arranged from the inside to the outside. The heating layer 12 is a heating plate, and the heat insulation layer 13 is a vacuum layer formed by the heating plate and the inner and outer perimeter of the outer shell layer 14. This allows for a simple internal structure of the pot lid 1. At the same time, while ensuring the heat insulation effect of the heat insulation layer 13 on the heat generated by the heating layer 12, the heat insulation layer 13 can be easily constructed between the heating layer 12 and the outer shell layer 14 without the need for additional heat insulation material.

[0033] Furthermore, at least one of the inner surface of the inner liner 11 and the inner surface of the outer shell 14 is provided with a groove 111, and the two are joined together to form a mounting cavity (not shown). The heating plate is accommodated on one side of the mounting cavity, and the heat insulation layer 13 is formed on the other side of the mounting cavity. By forming a mounting cavity between the inner liner 11 and the outer shell 14, the heating layer 12 can be stably installed, and the heat insulation layer 13 can be better formed between the heating layer 12 and the outer shell 14. In this embodiment, specifically, as shown... Figure 3 , Figure 4 as well as Figure 5As shown, the inner surface of the outer shell layer 14 is flat, and an annular groove 141 is recessed on its outer periphery. The inner surface of the inner liner layer 11 has a circular groove 111, and the groove wall of the groove 111 extends outward in the circumferential direction to form a convex ring 1111. The convex ring 1111 is engaged in the annular groove 141. The heating plate is accommodated in the annular groove 141, and the thickness of the heating plate is less than the depth of the annular groove 141, so as to form the heat insulation layer 13 between the heating layer 12 and the inner surface of the outer shell layer 14. The snap-fit ​​connection between the inner liner layer 11 and the outer shell layer 14 makes the mounting cavity structure formed between them more stable, thereby better ensuring the stable installation of the heating plate and the stability of the heat insulation layer 13 structure.

[0034] In addition, such as Figure 2 and Figure 3 As shown, a sealing ring 15 is wrapped around the outer periphery of the lid 10. When the lid 1 is closed over the opening of the pot body 7, the sealing ring 15 is sandwiched circumferentially between the outer periphery of the lid 10 and the edge of the opening of the pot body 7. By setting the sealing ring 15, water vapor can be prevented from escaping through the gap between the two during cooking and condensing into condensate. The resulting condensate flowing everywhere will affect the user experience.

[0035] Furthermore, such as Figure 2 As shown, a handle 21 is integrally formed on the outer surface of the outer shell layer 14, thereby facilitating the lifting of the pot lid 1. Meanwhile, as... Figure 1 and Figure 3 As shown, the device also includes a stirrer 3, which comprises a stirring claw 31 disposed inside the lid 10 for stirring food and a drive structure 32 for driving the stirring claw 31 to rotate. The drive structure 32 includes a drive motor 321 axially inserted into the central hole 100 of the lid 10. Furthermore, it includes a connecting arm 4 mounted on the outer surface of the outer shell layer 14. One end of the connecting arm 4 covers the central hole 100 and has a motor base 41 for mounting the drive motor 321, while the other end is a hinge seat 42 for hinged to a mounting base 51 fixed on the operating table 5. In operation, the rotation of the stirring claw 31 enables automatic stirring and stir-frying of the food. The connecting arm 4 allows the lid 1 to be rotated on the operating table 5, facilitating its placement on or removal from the opening of the pot body 7, and also ensures the stable mounting of the drive motor 321 on the lid 1. In this embodiment, the handle 21 is mounted on the handle base 2, and one side of the handle base 2 is provided with a clearance notch 22 for the motor base 41 of the connecting arm 4 to be inserted. Figure 2 and Figure 4 As shown.

[0036] In addition, such as Figure 4 and Figure 5As shown, the heating plate is provided with a positive electrode plate 61 and a negative electrode plate 62, and each electrode plate has a contact post 63. The connecting arm 4 is provided with a socket 43 corresponding to each contact post 63. Figure 5 The other side of the socket 43 is blocked and not shown. Each socket 43 is provided with a contact (not shown). Each contact post 63 is inserted into the corresponding socket 43 and electrically connected to the contact of the socket 43, so as to provide normal power to the heating plate and ensure the heating function of the heating plate.

[0037] The cooking machine can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the cooking machine to perform corresponding operations, thereby realizing intelligent control of the cooking machine and improving the user experience.
