A preferred embodiment of the present invention will be described with reference to fig. 4 to 10.

As shown in fig. 4, the cooking utensil 20 according to the present invention includes a pot body (not shown in the figure) and a cover assembly 1. The pot body is generally constructed in a rounded rectangular parallelepiped shape, and an inner pot 21 is provided inside thereof. The inner pot 21 may be configured to be removably disposed in the pot body to facilitate removal for cleaning. The lid assembly 1 is provided to the pot body in an openable and closable manner. Therefore, the lid assembly 1 generally has a shape adapted to the shape of the pot body so as to closely cover the pot body. When the cover assembly 1 is opened relative to the pot body, the opening of the inner pot 21 in the pot body is exposed, and a user can add food materials to the inner pot 21 or take cooked food out of the inner pot 21. When the cover body assembly 1 is covered on the cooker body, the cover body assembly covers the inner pot 21 and forms a cooking space with the inner pot 21.

Hereinafter, the cover assembly 1 according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 4 to 6, the cap body assembly 1 includes an upper cap 2 and an inner cap assembly including an inner cap 3 and a sealing ring 12. In the illustrated embodiment, the inner lid 3 is connected below the upper lid 2 for closing the inner pot 21 during cooking. And, inner cup 3 can be dismantled for upper cover 2 to the convenience of customers is dismantled and is washd inner cup 3 at any time. The sealing ring 12 is located between the inner lid 3 and the inner pot 21 and is attached to the inner lid 3. In particular, the sealing ring 12 is directly connected to the inner cap 3 without passing through any intermediate part. Preferably, the sealing ring 12 is a separate member from the inner cap 3, that is, it is a non-integrally formed integral piece, so that the sealing ring 12 and the inner cap 3 can be separately manufactured or can be manufactured in different factories as required, thereby improving convenience and flexibility. More preferably, the sealing ring 12 is removable with respect to the inner cap 3 to facilitate cleaning or replacement, respectively, of the sealing ring 12 and the inner cap 3. In particular, the sealing ring 12 is arranged in a ring shape to be correspondingly sealingly arranged around the inner lid 3. And the sealing ring 12 may be made of an elastic material such as rubber, silicon gel, etc. to seal against steam generated during cooking. It should be noted that the directional terms such as "upper", "lower", etc. mentioned herein are all relative to the cooking appliance placed on a horizontal surface.

Fig. 7 shows a preferred embodiment of the connection of the sealing ring 12 with the inner cap 3. Specifically, the seal ring 12 includes a first flange portion 13 that is surrounded along the entire circumferential length thereof. Accordingly, the outer edge of the inner lid 3 is provided with a second flange portion 14 that engages with the first flange portion 13. The first flange portion 13 may be wrapped outside the second flange portion 14 so that the seal ring 12 may be fitted to the inner lid 3. Preferably, as shown in connection with fig. 9, the first flange portion 13 is provided with a lateral opening 16 so that the second flange portion 14 enters the space defined inside the first flange portion 13 via the opening 16.

As shown in fig. 9 and 10, the first flange portion 13 and the second flange portion 14 are preferably arc-shaped in cross section. It will be appreciated that the smoothly transitioning arcuate cross-section allows the second flange portion 14 to easily enter the interior of the first flange portion 13 through the opening 16 without being affected by the frictional forces of the contacting surfaces. Therefore, this facilitates the fitting between the first flange portion 13 and the second flange portion 14, and can improve the sealing property.

Further preferably, the extension angle of the first flange portion 13 and the second flange portion 14 in the circumferential direction is greater than or equal to 270 °, so that the first flange portion 13 and the second flange portion 14 have a substantially unclosed circular cross section. In the case where the first flange portion 13 and the second flange portion 14 have arc-shaped cross sections, this scheme makes the contact area when the two are assembled as large as possible, so that the second flange portion 14 coated outside the first flange portion 13 is restrained by a radial force. Therefore, it is possible to improve the assembling tightness of both, and to prevent the first flange portion 13 from falling off from the second flange portion 14. Exemplarily, the extension angle of the first flange part 13 and the second flange part 14 in the circumferential direction may be 280 °, 285 °, and the like, and those skilled in the art can set the extension angle according to actual needs. In the above manner, the seal ring 12 can be directly attached to the inner lid 3 without any additional fastener, and can be easily detached from the inner lid 3. This reduces the number of parts, the assembly process difficulty and the production cost.

With further reference to fig. 7 and 9, the sealing ring 12 further includes an abutting portion 15 extending obliquely downward from the lower end of the first flange portion 13, the abutting portion 15 being sealed against the flange to the inner pot 21 in the covered state where the lid assembly 1 is covered to the pot body. The abutment 15 preferably has an upwardly curved curvature. Preferably, the maximum angle a formed between the extension direction of the abutment 15 and the horizontal plane is less than 90 °. It can be understood that in the closed state of the cover body assembly 1, the sealing ring 12 is subjected to the force applied by the cover body assembly 1 towards the inner pot 21, so that the abutting part 15 of the sealing ring 12 is further compressed to tend to abut against the flanging of the inner pot 21 in parallel, and the sealing of the cooking space is completed; meanwhile, the abutting portion 15 generates a reverse acting force against deformation caused by the acting force of the inner pot 21 thereto, so that the contact surface of the abutting portion 15 with the inner pot 21 tends to be more closely attached to the inner pot 21, thereby enhancing the sealing of the cooking space. Further preferably, the angle a satisfies: 30 degrees is more than A and less than 60 degrees. This preferred embodiment may further improve the sealing effect between the abutment 15 and the inner pot 21.

As shown in fig. 5 and 8, the inner lid 3 is further provided with a mounting sleeve 5, and the mounting sleeve 5 is made of an elastic material such as rubber, silicone, or the like. The upper cover 2 is provided with an installation shaft 4 extending along the direction towards the inner cover 3, and the installation sleeve 5 can be sleeved on the installation shaft 4 and can be taken down from the installation shaft 4, so that the inner cover 3 can be detachably installed on the upper cover 2. Further, a through hole 7 is formed in the inner cover 3, an annular clamping groove 8 is formed in the mounting sleeve 5, and the end portion, which surrounds the through hole 7, of the inner cover 3 can be inserted into the clamping groove 8, so that the mounting sleeve 5 can be mounted on the inner cover 3. Preferably, the end of the inner cap 3 surrounding the through hole 7 is configured to have a U-shaped structure to fill the space of the catching groove 8 as much as possible with the volume of the U-shaped structure, thereby reducing unnecessary slight relative movement, increasing the tightness of the fit of the inner cap 3 and the catching groove 8, and improving the stability of the assembly. Furthermore, a hole is provided in the mounting sleeve 5 which is fittable to the outer radial dimension of the mounting shaft 4, around which hole a clamping groove 8 is formed, via which the mounting sleeve 5 can be arranged on the mounting shaft 4 and can be moved on the mounting shaft 4 in its axial direction. Accordingly, the inner lid 3 is movably connected to the upper lid 2 by the mounting sleeve 5 so as to be movable in the height direction of the cooking appliance 20.

Preferably, the mounting sleeve 5 is disposed substantially in the middle of the inner lid 3. It will be appreciated that the mounting sleeve 5 contacts and applies a force to the inner lid 3 at a central position of the inner lid 3 so that the point of application of the force to the inner lid 3 can substantially coincide with its own center of gravity, whereby the inner lid 3 can have a stable equilibrium state. This therefore makes it possible to optimize the form of the force, increasing the stability of the inner lid 3 in the assembled state.

As shown in fig. 8, the upper portion of the mounting sleeve 5 is further provided with an elastic member 9, and the elastic member 9 is connected to a portion constituting the catching groove 8 and extends toward the upper cover 2. Specifically, the elastic member 9 can abut against the upper cover 2 as the inner cover moves in the height direction of the cooking appliance 20 to be elastically deformed, and also can form a seal between the inner cover 3 and the upper cover 2. Preferably, the longitudinal section of the elastic element 9 has an arc shape, which solution further facilitates the deformation of the elastic element 9 when it is applied against the upper cover 2. When the elastic member 9 is deformed, a downward force is applied to the inner lid 3, so that the abutting portion 15 of the inner lid 3 can be tightly attached to the inner pot 21, which will be described in detail below. The elastic member 9 is preferably deformed by 1 to 20mm, more preferably by 4 to 6mm, and for example, the elastic member 9 may be deformed by 4mm, 5mm, or 6 mm. Further, the upper end of the elastic element 9 is provided with a sealing surface 10, the bottom of the upper cover 2 is provided with an abutting surface 11 matched with the sealing surface 10, and the sealing surface 10 is tightly attached to the abutting surface 11 in a sealing state. It should be noted that, in order to clearly show that the elastic member 9 has a certain amount of elastic deformation and compression when abutting against the upper cover, fig. 8 shows that the elastic member 9 extends through a part of the upper cover 2, but actually the elastic member 9 only abuts against the upper cover 2 and does not pass through the upper cover 2.

Preferably, the end of the mounting shaft 4 is provided with a ring of stop flanges 6, so that the mounting shaft 4 is substantially inverted T-shaped. The stop flange 6 prevents the mounting sleeve 5 from falling off the mounting shaft 4. When the cooking is finished and the user intends to clean the inner cover 3, the user can pull the inner cover 3 by hand to separate the mounting sleeve 5 on the inner cover 3 from the mounting shaft 4, so as to finish the disassembly and facilitate the cleaning. Because the mounting sleeve 5 is made of elastic material, the mounting sleeve 5 can be conveniently sleeved on the mounting shaft 4.

In the closing process of the cover body assembly 1, the inner cover 3 firstly contacts the flanging of the inner pot 21, and because the inner pot 21 is stationary, an upward acting force is applied to the inner cover 3, and under the acting force, the mounting sleeve 5 on the inner cover 3 moves upwards along the mounting shaft 4, so that the elastic piece 9 on the upper part of the mounting sleeve 5 contacts the abutting surface 11 of the stationary upper cover 2 to generate deformation; when the cover assembly 1 is completely covered, the inner cover 3 stops moving upwards, and due to the fact that the elastic piece 9 is in a pressed deformation state, downward reaction force can be applied to the inner cover 3 by the generated elastic force, and therefore the abutting portion 15 of the sealing ring 12 abuts against the turned edge of the inner pot 21 tightly, air leakage is prevented, and therefore sealing of the sealing ring 12 to the cooking space can be further enhanced through matching of the movable inner cover 3 and the elastic piece 9.

According to the above technical scheme of the utility model, the dismouting process of inner cup 3 has been simplified on the one hand to can convenience of customers carry out the dismouting operation. On the other hand, through the cooperation of installation cover 5 and elastic component 9, can also improve sealed precision, reduce the gas leakage probability.
