The upper cover assembly is mainly used to centrally mount various functional components of the cover body 20 for sensing and controlling the working state of the cooking appliance, such as sensors, etc. The detachable cover is located at the innermost side of the cover body 20 and is arranged below the lining cover. The detachable cover is detachably connected to the lining cover, for example by buckling, to facilitate cleaning and replacement. The detachable cover is used to face the cooking space, i.e. when the cover body 20 is in the closed position, the detachable cover is located directly above the cooking space.

[0122] The cover body 20 is provided with a steam passage 22. The steam passage 22 can be in communication with the cooking space, and the steam passage 22 can be in communication with the outside. In one example, the steam passage 22 is surrounded by the lining cover and the detachable cover, i.e. the steam passage 22 is formed between the lining cover and the detachable cover. In one example, the cover body 20 is provided with an exhaust structure having the steam passage 22, which is respectively sealingly connected to the lining cover and the detachable cover to communicate the cooking space with the outside. In this scheme, the steam passage 22 is mainly used to control the discharge of steam to prevent excessive steam pressure in the cooking appliance. The steam passage 22 does not have the function of automatically adjusting the pressure, but relies on manual operation or a preset threshold to control the discharge of steam.

[0123] The present scheme is provided with a micro-pressure valve 30 in the cover body 20. The micro-pressure valve 30 is provided with a steam chamber 101, a micro-pressure valve air outlet 102 and a micro-pressure valve air inlet 103 in communication with the steam chamber 101, and the steam chamber 101 is in communication with the steam passage 22 through the micro-pressure valve air inlet 103. The micro-pressure valve 30 can adjust the pressure in the pot, and when the pressure reaches a certain degree, it will automatically release excess steam to keep the pressure in the pot stable. By the setting of the micro-pressure valve 30, the cooking process is carried out in a micro-pressure environment to accelerate the cooking speed of food, while retaining the nutritional ingredients and original flavor of the food.

[0124] As shown in Figure 10 and Figure 11As shown, the cover 20 is optionally provided with a mounting groove 21 for mounting the micro-pressure valve 30. The mounting groove 21 is optionally formed in the gasket. In some embodiments, the bottom of the mounting groove 21 is open to serve as an outlet end of the steam passage 22. The micro-pressure valve inlet 103 is sealingly connected to the outlet end of the steam passage 22 to fluidly connect the steam chamber 101 and the steam passage 22. The micro-pressure valve 30 can be inserted into the opening at the bottom of the mounting groove 21.

[0125] The micro-pressure valve 30 is optionally detachably connected to the mounting groove 21, so that the user can easily detach the micro-pressure valve 30 from the cover 20 for cleaning or replacement, thereby improving the maintenance convenience of the cooking appliance. The connection between the micro-pressure valve 30 and the mounting groove 21 includes but is not limited to plug-in connection, clamping connection.

[0126] In the present application, the micro-pressure valve 30 is provided with a decorative piece 200. The decorative piece 200 not only serves the purpose of decoration, but also serves the purpose of mounting to the external structure. Specifically, the decorative piece 200 is used to mount to the mounting groove 21 of the cover 20. The provision of the decorative piece 200 improves the aesthetic appearance of the micro-pressure valve 30, and makes it more harmonious and unified with the overall style of the cooking appliance.

[0127] The decorative piece 200 is optionally made of transparent material or translucent material. In some embodiments, the decorative piece 200 is provided with a visible area made of transparent material or translucent material. In other embodiments, the mounting groove 21 is provided with a decorative area provided with patterns or decorative lines. In the state where the micro-pressure valve 30 is mounted to the mounting groove 21, the micro-pressure valve 30 covers the decorative area, and the decorative area corresponds to the visible area. When the micro-pressure valve 30 is mounted to the mounting groove 21, the user can still see the patterns or decorative lines of the decorative area through the visible area of the decorative piece 200, thereby maintaining the overall aesthetic appearance.

[0128] The decorative piece 200 is optionally exposed on the surface of the cover 20, and the decorative piece 200 is provided with a handle 240 that is tilted away from the lower cover 300. The handle 240 is spaced apart from the surface of the cover 20. The provision of the handle 240 facilitates the user to hold and operate the micro-pressure valve 30, thereby improving the convenience of use.

[0129] The following will be described in detail Figures 1 to 11 The micro-pressure valve 30 will be described.

[0130] The micro pressure valve 30 comprises a micro pressure valve body 100, a decoration piece 200 and a lower cover body 300. The micro pressure valve body 100 comprises an upper mounting portion 110 and a lower mounting portion 120 connected in the axial direction thereof. In the present scheme, the axial direction of the micro pressure valve body 100 is the up-down direction of the cooking appliance. The upper mounting portion 110 has a first end portion 111 and a second end portion 112 in the axial direction, and the outer diameter of the first end portion 111 is larger than that of the second end portion 112. The decoration piece 200 is connected to the outer peripheral side of the upper mounting portion 110. The decoration piece 200 is used for mounting to the external structure. In the present scheme, the micro pressure valve body 100 is provided with a variable diameter, which constitutes a limit to the axial upward direction of the decoration piece 200. The lower cover body 300 is connected to the lower mounting portion 120. In some embodiments, the decoration piece 200 is limited axially between the first end portion 111 and the lower cover body 300. The provision of the lower cover body 300 not only provides additional structural support for the micro pressure valve 30, but also ensures that the downward movement of the decoration piece 200 in the axial direction is limited. In the present scheme, the first end portion 111 of the micro pressure valve body 100 and the lower cover body 300 form a limit to the decoration piece 200 in two directions in the axial direction, so that the decoration piece 200 is effectively supported and fixed in the axial direction, and therefore does not need additional fixing parts to maintain stability, simplifying the structure and assembly process of the micro pressure valve 30 and improving the assembly efficiency. In some embodiments, the decoration piece 200 is fixedly connected with the upper mounting portion 110. Alternatively, the fixed connection between the decoration piece 200 and the upper mounting portion 110 includes but is not limited to snap connection, slot connection. In the present scheme, the fixed connection ensures the close fit between the decoration piece 200 and the upper mounting portion 110, which is not easy to loosen or fall off due to vibration or external impact. On the basis of the foregoing embodiments, while the decoration piece is fixedly connected with the upper mounting portion 110, the lower cover body 300 further limits the decoration piece 200. Through the dual action of fixed connection and limiting structure, the position of the decoration piece 200 in the micro pressure valve 30 is more stably fixed, thereby effectively reducing the loosening or falling off phenomenon caused by vibration or external impact, thereby improving the overall stability of the micro pressure valve 30.

[0131] In some embodiments of the present application, the outer diameter of at least part of the upper mounting portion 110 gradually increases in the direction from the second end portion 112 to the first end portion 111. That is, the upper mounting portion 110 of the micro pressure valve body 100 is configured as a circular truncated cone or a stepped shape. Alternatively, the transition between the first end portion 111 and the second end portion 112 of the upper mounting portion 110 can be continuous and smooth, or segmented and stepped.

[0132] As the outer diameter of the upper mounting portion 110 gradually increases, the decorative piece 200 will gradually contact different diameter portions of the upper mounting portion 110 during the installation process. When the decorative piece 200 is completely installed in place, the larger diameter will prevent it from moving further towards the first end portion 111. The decorative piece 200 is tightly fitted with the largest diameter portion of the upper mounting portion 110, forming a stable installation state.

[0133] The inner peripheral wall of the decorative piece 200 is adapted to the outer peripheral wall of the micro-pressure valve body 100. Specifically, the inner peripheral wall of the decorative piece 200 is adapted to the outer peripheral wall of the upper mounting portion 110.

[0134] Optionally, the inner diameter of the decorative piece 200 gradually increases in the direction away from the lower cover body 300. The decorative piece 200 is adapted to the upper mounting portion 110 of the micro-pressure valve body 100, ensuring that the decorative piece 200 can be stably installed on the micro-pressure valve body 100.

[0135] In this scheme, the first end portion 111 is located above the second end portion 112. Through the above scheme, the upward limit of the decorative piece 200 along the axial direction is realized, i.e. Figure 1 The upward movement limit is shown. The following describes the downward limit of the decorative piece 200 along the axial direction in combination with specific embodiments.

[0136] Referring to Figure 4 and Figure 5 the first embodiment, the decorative piece 200 is axially limited between the first end portion 111 and the lower cover body 300.

[0137] The lower cover body 300 abuts against the decorative piece 200 along the axial direction. Therefore, the lower cover body 300 can limit the axial displacement of the decorative piece 200. In the state that the lower cover body 300 is assembled to the micro-pressure valve body 100, the limiting structure of the lower cover body 300 will prevent the decorative piece 200 from moving downward along the axial direction.

[0138] Optionally, the outer diameter of the lower cover body 300 is smaller than the inner diameter of the decorative piece 200. Since the outer diameter of the lower cover body 300 is smaller than the inner diameter of the decorative piece 200, the lower cover body 300 can be tightly fitted below the decorative piece 200, thereby preventing the decorative piece 200 from moving downward along the axial direction.

[0139] Referring to Figure 6 and Figure 7 the second embodiment, the decorative piece 200 is fixedly connected with the upper mounting portion 110.

[0140] The micro-pressure valve body 100 is provided with a first limiting part 130, and the decoration piece 200 is provided with a second limiting part 210, and when the decoration piece 200 is installed to the micro-pressure valve body 100, the first limiting part 130 is clamped with the second limiting part 210. Therefore, the clamping of the first limiting part 130 and the second limiting part 210 can limit the axial displacement of the decoration piece 200. The scheme can ensure the stable installation of the decoration piece 200 on the micro-pressure valve body 100, and prevent the decoration piece 200 from falling off or loosening due to vibration, impact or other external factors during use.
