Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that embodiments of the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail so as not to obscure the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art.

As shown in fig. 1 to 3, the present invention provides a pressure cooking appliance, which mainly comprises a lid body 10 and a pot body 20. The pot body 20 is substantially in a rounded rectangular parallelepiped shape and has a cylindrical-shaped inner pot receiving portion into or from which the inner pot 21 can be freely put or taken out to facilitate the cleaning of the inner pot 21. The inner pot 21 is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. An inner pan gasket 22 is arranged on the upper surface of the pot body 20 at a position surrounding the inner pan 21. When the pressure cooking appliance works, the temperature of the inner pot 21 is high, the inner pot gasket 22 can isolate the inner pot 21 from other parts of the cooker body 20, so that the heat insulation and burn prevention effects are achieved, and the other parts are prevented from being damaged due to the high temperature of the inner pot 21. In addition, a heating device for heating the inner pot 21, etc. may be provided inside the pot body 20.

The lid body 10 may have a shape substantially corresponding to the shape of the pot body 20. The lid body 10 is pivotally connected to the pot body 20 in an openable and closable manner for covering the pot body 20. When the lid 10 is closed on the pot body 20, it covers the inner pot 21 and forms a cooking space with the inner pot 21. Also, the lid body 10 is usually provided with a sealing ring, which may be made of, for example, a rubber material, and is disposed between the lid body and the inner pot 21 for sealing the cooking space when the lid body is in a closed state.

The pressure cooking appliance shown in the invention can be an electric pressure cooker, an electric pressure cooker or other pressure cooking appliances, and the pressure cooking appliance according to the invention can have various functions of cooking rice, cooking porridge, cooking soup and the like. When the pressure cooking appliance works, the cooking space is filled with steam, and the pressure is higher than the external environment, so that the requirements on the connection and sealing between the cover body 10 and the cooker body 20 are higher, and the steam in the cooking space is prevented from leaking to influence the cooking effect. Therefore, the hook 11 is provided on the lid 10, and the hook connecting plate 23 is provided on the pot body 20. When the lid body 10 is closed with the pot body 20, the hook 11 is hooked on the hook connection plate 23, and the lid body 10 can be opened only by releasing the connection between the hook 11 and the hook connection plate 23.

Specifically, as shown in fig. 3 and 4, the hook 11 is rotatably connected to a side of the cover 10 facing the pot body 20 by a rotation shaft 12. Wherein, a hooking part 111 is provided at one end of the hook 11 close to the pot body 20. The hook connecting plate 23 is fixedly arranged below the inner pot washer 22 of the cooker body 20. When the cover body 10 covers the pot body 20, the hooking part 111 of the hook 11 extends into the lower part of the hook connecting plate 23 and hooks the hook connecting plate 23, thereby increasing the connecting strength between the cover body 10 and the pot body 20 when the cover body is covered. Since the pressure cooking appliance generates a large pressure in the cooking space when it is operated, in order to prevent the pot body 20 and the lid body 10 from being separated by the excessive pressure, which may cause damage to a user or the surrounding environment, it is necessary to secure the coupling strength between the hooks 11 and the hook coupling plate 23. Therefore, preferably, the hook 11 and the hook connecting plate 23 may be made of a metal material so that the hooking between the hook 11 and the hook connecting plate 23 is strong enough to resist the pressure in the cooking space. Further preferably, the rotating shaft 12 is provided with a torsion spring 13, the torsion spring 13 penetrates through the rotating shaft 12, one end of the torsion spring 13 abuts against the inner side of the cover 10, the other end of the torsion spring 13 abuts against the hook 11, and the torsion spring 13 acts on the hook 11 to enable the hooking part 111 of the hook 11 to have a tendency to move towards the hook connecting plate 23 in the horizontal direction, so that the torsion spring 13 biases the hook 11 towards a hooking position where the hook connecting plate 111 can be hooked tightly. Therefore, when the hooking part 111 is located below the hook connecting plate 23, the torsion spring 13 can ensure that the hooking part 111 is not separated, thereby ensuring the hooking between the hook 11 and the hook connecting plate 23.

The hook connecting plate 23 is arranged below the inner pot washer 22, and in the process of covering the cover body 10, the hook 11 needs to extend into the lower part of the hook connecting plate 23 through the inner pot washer 22. Because there is the installation clearance between interior pot packing ring 22 and the couple connecting plate 23, consequently, sometimes the phenomenon that the hook portion 111 of couple 11 catches on the edge of interior pot packing ring 22 appears, and the joint strength between lid 10 and the a kind of deep pot body 20 is less like this, if the user begins to cook, has the danger that pressure cooking utensil automatic uncap, causes steam to leak, even causes the harm to user or surrounding environment. Therefore, as shown in fig. 5, the hooking link plate 23 is provided to extend beyond the inner pot ring 22 at the edge by a predetermined distance D, and it is preferable that a height distance between the lower surface of the edge of the inner pot ring 22 and the upper surface of the edge of the hooking link plate 23 is smaller than the thickness of the hooking portion 111 of the hook 11. Therefore, the phenomenon that the hook 11 is hooked on the inner pot gasket 22 can be avoided, and the potential safety hazard is eliminated to a certain extent. Wherein, the range of the predetermined distance D of the hook connecting plate 23 beyond the inner pot gasket 22 is 0-0.5 mm. Within such a range, the hook portion 111 of the hook 11 is not prevented from extending below the hook connecting plate 23 while avoiding the false hooking phenomenon. In an embodiment not shown, the hook may also be flush with the inner pot washer.

The hook 11 passes through the inner pot washer 22 while extending below the hook connection plate 23, and thus, as shown in fig. 4, it is preferable that a guide slope 221 is provided on the inner pot washer 22. The guiding inclined plane 221 extends outwards and downwards at the edge of the inner pot gasket 22, so that the hooking part 111 of the hook 11 is guided by the guiding inclined plane 221 when passing through the inner pot gasket 22, and the cover closing operation is convenient. Further preferably, the guide slope 221 is provided as a smooth surface, so that the friction between the guide slope 221 and the hooking portion 111 can be reduced, and the cover can be easily closed.

Further, it is preferable that the edge of the hooking portion 111 of the hook 11 and the outer edge of the hook connecting plate 23 are rounded or chamfered, so that the hooking portion 111 passes the edge of the hook connecting plate 23 smoothly and smoothly, and the seizure can be reduced.

According to the pressure cooking appliance, the hook connecting plate is flush with the inner pot gasket or extends beyond the inner pot gasket at the outer edge, and when the cover body is covered, the hook can be hung below the hook connecting plate, so that the phenomenon of false hanging is avoided, and the potential safety hazard of the pressure cooking appliance in the use process is eliminated to a certain extent.
