DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0038] At present, there are various kinds of cooking utensils, including electric rice cookers, pressure cookers, electric stew pots, etc. Take the pressure cooker as an example, it has been widely used in family life. According to the different needs of food, it is cooked in two states of closing the lid and opening the lid, and the opening and closing of the pressure cooker lid needs to be detected.

[0039] The pressure cooker includes an upper cover and a pot body, the upper cover includes a cover body, a lid and a detected piece, the cover body covers the pot body, the lid has a locking position for cooperating with the pot body to lock the buckle and an unlocking position for cooperating with the pot body to unlock the buckle, and the position of the lid is detected by the cooperation of the detected piece and the detection device.

[0040] However, the detected piece is exposed on the surface of the upper cover in the related art, so that the detected piece is easily damaged by the external environment. The detected piece can be protected by designing a protective cover, but the design of the protective cover increases the overall volume of the upper cover.

[0041] Based on this, please refer to Figures 1 to 4 The upper cover 1 and the cooking utensil provided in the embodiments of the present application aim to improve the problem that the detected piece 15 is easily affected by the external environment.

[0042] In the embodiments of the present application, the cooking utensil can include one of a pressure cooker, an electric rice cooker, an electric stew pot, a soybean milk machine and a juicer, and the specific type of the cooking utensil is not limited in the embodiments. In order to facilitate the description of the following content, the cooking utensil in the following embodiments is a pressure cooker, and the advantages of the cooking utensil of the present application for easy opening and closing of the cover are introduced in detail.

[0043] The cooking utensil includes a pot body and an upper cover 1, the pot body includes an outer shell, an inner container and a detection device 2, the inner container and the detection device 2 are both installed on the outer shell, and the upper cover 1 is coverably arranged on the outer shell. The outer shell can be made of many materials, the outer shell can be made of metal material, the outer shell can also be made of hard plastic, and the outer shell can also be made of other materials, which are not limited here.

[0044] The inner container is used for directly containing food, and is detachably arranged on the outer shell, which is convenient for users to clean and replace, can also prevent users from directly contacting the surface of the heated inner container, and reduces the risk of scalding; the outer shell can be provided with a heat preservation layer to reduce heat loss, so that the food in the inner container can be heated more quickly and uniformly. The upper cover 1 is usually provided with a weight and an exhaust valve core, the exhaust valve core is mainly used for controlling the release of pressure in the pot. When the pressure in the pot reaches a certain level, the exhaust valve core will open to allow steam to be discharged, so as to prevent the pressure from being too high to cause danger. The weight usually cooperates with the exhaust valve core as a safety device. When the pressure in the pot is too high and the exhaust valve core cannot release the pressure in time or completely, the weight will be lifted by the steam pressure, serving as a second line of defense to forcibly release the pressure and prevent the pot body from being broken.

[0045] The upper cover 1 comprises an inner cover 11, a face cover 12, a pot cover 13, a transmission member 14 and a detected member 15. The face cover 12 is mounted on the inner cover 11. The pot cover 13 is used to seal the inner container to form a cooking cavity. The pot cover 13 is rotatably mounted on the inner cover 11 and located on the side of the inner cover 11 away from the face cover 12. The pot cover 13 has a locking position for cooperating with the pot body to lock the pot body and an unlocking position for cooperating with the pot body to unlock the pot body. The pot cover 13 is provided with a transmission part 131. The transmission part 131 penetrates through the inner cover 11 and extends into the space between the inner cover 11 and the face cover 12. The transmission member 14 is fixedly connected with the transmission part 131 and located between the inner cover 11 and the face cover 12. The detected member 15 is mounted on the transmission member 14 and is switched between a detection position and a disengagement position under the driving of the transmission member 14. The detected member 15 is used to trigger the detection device 2. The pot cover 13 is rotated to drive the transmission member 14 to move, so as to drive the detected member 15 to switch between the detection position and the disengagement position. When the detected member 16 is located at the detection position, the detected member 15 triggers the detection device 2. When the detected member 16 is located at the disengagement position, the detected member 15 cannot trigger the detection device 2.

[0046] The face cover 12 is arranged on the outermost part and serves to mount components, protection and aesthetics. The face cover 12 can be composed of components of at least two different materials such as plastic, glass and metal. In this way, the face cover 12 has high structural strength, better appearance and gloss, and can improve the aesthetics of the cooking appliance. The face cover 12 at least partially covers the inner cover 11. That is, the face cover 12 can completely cover the inner cover 11 or partially cover the inner cover 11. No specific limitation is made herein.

[0047] In one structure, the inner cover 11 is annular. The inner cover 11 provides fixation and support for the pot cover 13. The pot cover 13 is used in cooperation with a sealing ring to form a sealed space with the cooking cavity of the inner container. The pot cover 13 can be made of stainless steel. The weight and the exhaust valve core are mounted on the pot cover 13 and the face cover 12. It can be understood that in other embodiments, the pot cover 13 can be annular and used to fix the sealing ring in cooperation with the inner cover 11 or the sealing ring is fixed by the pot cover 13 alone. The pot cover 13 is buckled on the pot opening of the inner container, and the sealing of the entire pot opening of the inner container is realized by the inner cover 11.

[0048] When the pot cover 13 is located at the locking position, the pot cover 13 is tightly connected with the inner container to form a closed limited volume space, so that the steam in the inner container is firmly sealed to ensure that the pressure in the inner container remains at a high level during the heating operation or at the end of cooking.

[0049] The pot cover 13 is provided with a transmission part 131, the transmission part 131 is fixedly connected with the transmission part 14 through the inner cover 11, and the transmission part 131 rotates with the pot cover 13 and drives the transmission part 14 to move. It can be understood that the inner cover 11 is provided with an activity channel 112 extending along the circumference of the pot cover 13, and the opposite walls of the activity channel 112 are provided through the inner cover 11 to allow the transmission part 131 to pass through the inner cover 11. Since the outer circumferential wall of the pot cover 13 needs to be sealed with the inner container, the lower surface of the pot cover 13 is located in the inner container, so the transmission part 131 is formed by protruding from the upper surface of the pot cover 13.

[0050] When the inner cover 11 is provided with a convex 111 for accommodating the pot cover 13, the activity channel 112 can be provided on the outer circumferential wall of the convex 111, and the two walls of the activity channel 112 in the radial direction of the convex 111 are provided through the activity channel 112. At this time, the transmission part 131 at least partially extends along the radial direction of the convex 111. Specifically, the transmission part 131 can be inclined, and the transmission part 131 can be formed by an extension section and a connecting section. The extension section extends along the axial direction of the pot cover 13, and the connecting section extends along the radial direction of the convex 111 and is connected with the end of the extension section away from the pot cover 13. Here, they will not be listed one by one.

[0051] Preferably, referring to Figure 4 , the inner cover 11 is provided with an activity channel 112 extending along the circumference of the pot cover 13, and the activity channel 112 is provided through the inner cover 11 along the axial direction of the pot cover 13. The transmission part 131 is connected with the transmission part 14 through the activity channel 112. In this way, the transmission part 131 only needs to extend along the axial direction of the pot cover 13, thereby optimizing the structure of the pot cover 13 and facilitating the processing of the pot cover 13.

[0052] The shape of the transmission part 131 is various, the transmission part 131 can be cylindrical, the transmission part 131 can also be cuboid, and the transmission part 131 can also be other irregular shapes, which will not be limited here.

[0053] Please refer to Figure 4 , the number of transmission parts 131 is multiple, and the multiple transmission parts 131 are fixedly connected with the transmission part 14. In this way, the transmission stability of the pot cover 13 to the transmission part 14 can be improved, and when a single transmission part 131 is damaged, the transmission part 14 can also be driven to move by other transmission parts 131, thereby improving the service life of the upper cover 1.

[0054] The connection mode of the transmission part 131 and the transmission part 14 is various, the transmission part 131 can be inserted and matched with the transmission part 14, the transmission part 131 and the transmission part 14 can also be buckled and matched, and the transmission part 131 and the transmission part 14 can also be connected through screws, which will not be limited here. The transmission part 14 is made of various materials, the transmission part 14 can be made of metal material, and the transmission part 14 can also be made of hard plastic, which will not be limited here.

[0055] The detection piece 15 can be mounted on the transmission piece 14 by adhesion, can be mounted on the transmission piece 14 by buckling, or can be mounted on the transmission piece 14 by screw connection, and the specific mode is not limited herein. The detection piece 15 can trigger the detection device 2 by Bluetooth signal transmission, can trigger the detection device 2 by abutting, or can trigger the detection device 2 by magnetic signal, and the specific mode is not limited herein.

[0056] When the pot cover 13 is switched between the locked position and the unlocked position, the pot cover 13 drives the transmission piece 14 to move through the transmission part 131, and drives the detection piece 15 to switch between the detection position and the disengagement position, so that the movement of the pot cover 13 is synchronized with the movement of the detection piece 15, and thus the position of the pot cover 13 can be determined by determining the position of the detection piece 15.

[0057] When the pot cover 13 is located at the locked position, the detection piece 15 can be located at the detection position, and at this time, the detection piece 15 triggers the detection device 2, so as to identify that the pot cover 13 is located at the locked position. When the pot cover 13 is switched to the unlocked position, the detection piece 15 is switched to the disengagement position, and the detection piece 15 cannot trigger the detection device 2, so as to identify that the pot cover 13 is located at the unlocked position.

[0058] When the pot cover 13 is located at the locked position, the detection piece 16 can also be located at the disengagement position, and at this time, the detection piece 15 cannot trigger the detection device 2, so as to identify that the pot cover 13 is located at the locked position. When the pot cover 13 is switched to the unlocked position, the detection piece 15 is switched to the detection position, and the detection piece 15 triggers the detection device 2, so as to identify that the pot cover 13 is located at the unlocked position.

[0059] In the embodiment of the application, the upper cover 1 and the cooking utensil are characterized in that the transmission piece 14 and the detection piece 15 are arranged between the inner cover 11 and the face cover 12, so that the face cover 12 and the inner cover 11 can protect the transmission piece 14 and the detection piece 15, and the space between the inner cover 11 and the face cover 12 can be fully utilized to reduce the volume of the upper cover 1. Compared with the protection cover arranged to protect the detection piece 15, the face cover 12 and the inner cover 11 are used to protect the detection piece 15 in the embodiment of the application, so that the structure of the upper cover 1 is simplified, the assembly efficiency of the cooking utensil is improved, the cooking utensil is convenient to maintain, and the cost of the cooking utensil is reduced.

[0060] Please refer to Figure 4In some embodiments of the present application, the transmission member 14 has an extension portion 141 and a mounting portion 142, one end of the extension portion 141 is connected with the transmission portion 131, the other end of the extension portion 141 extends along the radial direction of the pot cover 13 and is connected with the mounting portion 142, the mounting portion 142 extends towards the direction close to the pot body, and the detected member 15 is mounted on the mounting portion 142. In this way, by mounting the detected member 15 on the mounting portion 142, the detected member 15 is arranged close to the detection device 2, so that the detected member 15 can better trigger the detection device 2, thereby avoiding misjudgment of the detection device 2. At the same time, the extension portion 141 extends along the radial direction of the pot cover 13, so that the mounting portion 142 can extend towards the direction close to the pot body to avoid interference between the mounting portion 142 and the pot cover 13, and to avoid the influence of the pot cover 13 on the detected member 15 triggering the detection device 2.

[0061] It should be noted that there are many ways to connect the extension portion 141 and the mounting portion 142, the extension portion 141 and the mounting portion 142 can be integrally formed, or the extension portion 141 and the mounting portion 142 can be detachably connected. Preferably, the extension portion 141 and the mounting portion 142 are detachably connected, so that when the extension portion 141 or the mounting portion 142 is damaged, only the corresponding damaged part needs to be replaced, thereby reducing the maintenance cost of the upper cover 1.

[0062] Specifically, referring to Figure 2 The detected member 15 is mounted on the end of the mounting portion 142 away from the extension portion 141. In this way, the detected member 15 is arranged close to the detection device 2, so that the detected member 15 can better trigger the detection device 2, thereby avoiding misjudgment of the detection device 2.

[0063] Further, referring to Figure 2 The inner cover 11 includes a convex portion 111 for accommodating the pot cover 13, the surface cover 12 is arranged on the convex portion 111, the mounting portion 142 is arranged opposite to the outer peripheral wall of the convex portion 111 and is located between the outer peripheral wall of the convex portion 111 and the surface cover 12. It can be understood that the mounting portion 142 extends along the outer peripheral wall of the convex portion 111 towards the direction close to the pot body. In this way, the space between the outer peripheral wall of the convex portion 111 and the surface cover 12 is fully utilized, thereby simplifying the structure of the inner cover 11. At the same time, the convex portion 111 accommodates the pot cover 13, so that the convex portion 111 plays a protective role for the pot cover 13.

[0064] Referring to Figure 4In some embodiments of the present application, the transmission member 14 further has a connecting portion 143, the extension portion 141 is connected with the transmission portion 131 through the connecting portion 143, and the connecting portion 143 is integrally formed with the extension portion 141. In this way, the connecting portion 143 is integrally arranged with the extension portion 141, thereby reducing the number of components of the upper cover 1, simplifying the structure of the upper cover 1, and further improving the assembly efficiency of the upper cover 1 as a whole.

[0065] Referring to Figure 4 In some embodiments of the present application, the transmission member 14 further has a connecting portion 143, the extension portion 141 is connected with the transmission portion 131 through the connecting portion 143, and the connecting portion 143 is integrally formed with the extension portion 141.
