Referring to fig. 1, an embodiment of the present invention provides an electric pressure cooker 100, which includes a cooker body 10 and a cooker cover 20, wherein the cooker cover 20 covers the cooker body 10 and defines a cooking space for cooking food with the cooker body 10.

Referring to fig. 2, in particular, the pot body 10 includes a base 11, an outer pot 12 and an inner pot 13, one end of the outer pot 12 is coupled to the base 11, and the other end extends in a direction away from the base 11 to define an accommodating cavity with an opening with the base 11, and the inner pot 13 is accommodated in the accommodating cavity from the opening. The cover 20 covers the outer pot 12 and defines the cooking space with the inner pot 13. The base 11 is provided with a heating mechanism 112 for heating food in the cooking space, and the lid 20 is provided with a pressure release valve 21 for releasing pressure in the cooking space.

Wherein at least a portion of the outer pot 12 is controllably separated from the lid 20 and/or the base 11 to form a communication port 50 (see fig. 3) communicating between the outside and the inner pot 13.

With the above arrangement, after the electric pressure cooker 100 finishes cooking, at least a portion of the outer pot 12 can be separated from the lid 20 and/or the base 11, so as to form the communication port 50 communicating between the outside and the inner pot 13, and outside air flows to the inner pot 13 through the communication port 50 and exchanges heat with the surface of the inner pot 13 (i.e. the whole indoor environment cools the inner pot 13). Therefore, the temperature in the inner pot 13 is reduced, when the temperature in the inner pot 13 is reduced, the pressure in the inner pot 13 is correspondingly reduced, and when the pressure in the inner pot 13 is reduced, the time required by pressure relief is shortened, so that the time required from the end of cooking to eating is saved.

In one embodiment, portions of the outer pot 12 are controllably separated from the lid 20 and/or the base 11. Specifically, the outer pot 12 comprises at least two connecting blocks which are arranged independently, and all the connecting blocks are butted to form the outer pot 12. Referring to fig. 4 and 5, a portion of the connection blocks is divided into a first connection block 121, the remaining portion of the connection blocks is divided into a second connection block 122, the first connection block 121 is controllably separated from the lid 20 and/or the base 11, and the second connection block 122 is connected between the base 11 and the lid 20.

Referring to fig. 3, that is, after cooking is finished, the first connection block 121 may be separated from the cover 20 and/or the base 11 to form the communication port 50 communicating between the outside and the inner pot 13. And the second connecting block 122 is always connected between the base 11 and the lid 20 to prevent the lid 20 from being pushed open by excessive pressure in the inner pot 13.

It is understood that in other embodiments, the entire outer pot 12 may be separate from the pot cover 20 and/or the base 11. As in one embodiment, the whole of the outer pot 12 is controllably separated from the cover 20, and when the cooking is finished, the whole of the outer pot 12 can be separated from the cover 20, but it is necessary that the electric pressure cooker 100 further includes a connection mechanism for controlling the connection mechanism to be connected between the base 11 and the cover 20 before the whole of the outer pot 12 is separated from the cover 20, so as to prevent the cover 20 from being washed away by the high pressure. In another embodiment, the whole outer pot 12 is separated from the base 11, and after cooking is finished, the whole outer pot 12 can be separated from the base 11, and at this time, it is also necessary that the electric pressure cooker 100 further includes a connection mechanism, and before the whole outer pot 12 is separated from the base 11, the connection mechanism is controlled to be connected between the base 11 and the cover 20, so as to prevent the cover 20 from being washed away under the action of high pressure. In another embodiment, all of the outer pot 12 may be separated from both the lid 20 and the base 11, and at this time, the electric pressure cooker 100 also needs to include a connection mechanism, and before all of the outer pot 12 is separated from one of the lid 20 and the base 11, the connection mechanism is controlled to be connected between the base 11 and the lid 20, so as to prevent the lid 20 from being opened under the action of high pressure.

Specifically, the first connecting block 121 is slidably connected to the base 11 and controllably slides relative to the base 11 in a direction away from the inner pot 13, so that the other end of the first connecting block 121 is separated from the pot cover 20 to form the communicating opening 50.

With reference to fig. 2, in one embodiment, the electric pressure cooker 100 further includes a movable member 30, the base 11 is provided with a sliding slot 111, the movable member 30 is slidably disposed in the sliding slot 111, the first connecting block 121 is slidably connected to the base 11 through the movable member 30, and the movable member 30 controllably slides in the sliding slot 111 to drive the first connecting block 121 to move in a direction away from the inner pot 13, so as to separate the outer pot 12 from the pot cover 20. It is conceivable that, in another embodiment, the electric pressure cooker 100 may omit the movable member 30, the base 11 is provided with a sliding slot 111, the first connecting block 121 is directly slidably disposed in the sliding slot 111, and the first connecting block 121 controllably slides in the sliding slot 111 to move in a direction away from the inner pot 13, so that the other end of the first connecting block 121 is separated from the pot cover 20 to form the communication opening 50.

Specifically, the electric pressure cooker 100 includes a control mechanism and a driving mechanism, the driving mechanism is connected to the control mechanism, and the movable member 30 is connected to the driving mechanism. The base 1111 has an operation panel 40 thereon, and the operation panel 40 is electrically connected to the control mechanism. After cooking is finished, the operation panel 40 can be operated to enable the control mechanism to control the driving mechanism to operate, and the driving mechanism drives the movable member 30 to move in the sliding slot 111 so as to drive the first connecting block 121 to move towards a direction away from the inner pot 13.

In one embodiment, after the first connection block 121 is separated from the lid 20, the first connection block 121 can rotate and expand relative to the base 11, and after the first connection block 121 expands, the communication area of the communication port 50 formed between the first connection block and the lid 20 is increased, so that more outside air can enter from the communication port 50 to exchange heat with the outer surface of the inner pot 13. That is, the first connecting block 121 and the second connecting block 122 of the outer pot 12 of the electric pressure cooker 100 provided by the present embodiment are similar to petals of a flower, the first connecting block 121 can be unfolded like when the petals meet, and the second connecting block 122 is always connected between the base 11 and the lid 20 (see fig. 3).

Referring to fig. 6, in particular, the movable member 30 includes a sliding member 31 and a rotating member 32, the sliding member 31 is slidably disposed in the sliding slot 111, the rotating member 32 is connected to the movable member 30, and the first connecting block 121 is rotatably connected to the rotating member 32. The sliding member 31 is controllably slidable in the sliding slot 111 to move the rotating member 32 and the first connecting block 121 in a direction away from the inner pot 13, and the first connecting block 121 is separated from the pot cover 20 and then rotatably unfolded relative to the rotating member 32.

It is contemplated that in other embodiments, the movable member 30 may be omitted from the electric pressure cooker 100, and the base 11 is provided with a sliding groove and a rotating groove which are communicated with each other, when the first connecting block 121 slides from the sliding groove to the rotating groove, the first connecting block 121 is separated from the lid 20, and the first connecting block 121 rotates and unfolds in the rotating groove.

In one embodiment, the first connecting block 121 can be rotatably unfolded relative to the rotating member 32 under the effect of its own weight. That is, after the upper end of the first connecting block 121 is separated from the limit of the pot lid 20, since the lower end of the first connecting block 121 is rotatably connected to the rotating member 32, if the upper end of the first connecting block 121 is heavier than the lower end and the outer side of the upper end is heavier than the inner side, the first connecting block 121 is lowered and unfolded under the action of gravity. It is contemplated that in other embodiments, the upper end of the first connecting block 121 may be controlled by the control mechanism to be unfolded away from the limit of the lid 20, which is not limited herein.

Further, rotating member 32 is the installation pipe, and the mounting hole has been seted up to the one end that first linkage block 121 and rotation member 32 are connected, and the installation pipe is worn to locate in the mounting hole, and first linkage block 121 accessible mounting hole rotates with the installation pipe cooperation after first linkage block 121 and pot cover 20 separate.

Referring to fig. 7 and 8, in particular, the mounting tube includes a first semicircular tube 321 and a second semicircular tube 322 that are oppositely disposed, the sliding member 31 includes at least two semicircular tubes that are disposed at an interval, the first semicircular tube 321 is connected to a portion of the sliding member 31, and the second semicircular tube 322 is connected to the other portion of the sliding member 31. Wherein, a part of the first connecting blocks 121 are rotatably connected to the first semicircular pipe 321, the rest of the first connecting blocks 121 are rotatably connected to the second semicircular pipe 322, the second connecting block 122 is connected to the joint of the first semicircular pipe 321 and the second semicircular pipe 322, and the position between the second connecting block 122 and the base 11 is not changed when the first semicircular pipe 321 and the second semicircular pipe 322 move.

That is, after cooking is finished, the control mechanism controls the sliding member 31 to move in the sliding groove 111, the first semicircular tube 321 and the second semicircular tube 322 which are originally butted are separated to form an elliptical shape, at this time, the upper end of the first connecting block 121 is separated from the pot cover 20, and after the upper end of the first connecting block 121 is separated from the limit of the pot cover 20, the upper end is unfolded under the action of gravity. Because the second connecting block 122 is connected to the joint of the first semicircular tube 321 and the second semicircular tube 322, when the first semicircular tube 321 and the second semicircular tube 322 are separated from each other, the size of the joint changes slightly (i.e. after the circle changes into an ellipse, the diameter of the circle is equal to the short axis of the formed ellipse), so that the separation of the first semicircular tube 321 and the second semicircular tube 322 does not affect the second connecting block 122, and the second connecting block 122 is still fixed between the base 11 and the lid 20.

With continued reference to fig. 3 and 5, in one embodiment, the first connecting block 121 is provided to include 6 blocks, and the second connecting block 122 includes two blocks. When the first semicircular tube 321 and the second semicircular tube 322 are separated from each other, the 6 first connecting blocks 121 can be driven to move in a direction away from the inner pot 13, and when the first connecting blocks 121 move to the upper end and are separated from the pot cover 20, the first connecting blocks are unfolded. When the first semicircular tube 321 and the second semicircular tube 322 are separated from each other, the second connecting block 122 does not move relative to the pot cover 20 and the base 11. It is understood that in other embodiments, the first connection block 121 may also include 4 blocks, and the second connection block 122 may also include 4 blocks, which is not limited herein.

In addition, the first connection block 121 is provided as a retractable member, and when the first connection block 121 is separated from the pot cover 20, the first connection block 121 is controllably retracted. So as to reduce the occupation of more indoor space after the first connecting block 121 is unfolded.

In one embodiment, the electric pressure cooker 100 further comprises an auxiliary cooling mechanism (not shown) disposed on the base 11 for auxiliary cooling of the inner pot 13. Specifically, the auxiliary cooling mechanism is filled with cooling liquid, and the temperature of the inner pot 13 is reduced by heat exchange between the cooling liquid flowing in the auxiliary cooling mechanism and the surface of the inner pot 13.

More specifically, the auxiliary cooling mechanism has a first position housed in the base 11 and a second position protruding outside the base 11 with respect to the base 11, and is switched between the first position and the second position. When cooking, the auxiliary cooling mechanism is in the first position, and after the cooking is finished and the first connecting block 121 is separated from the pot cover 20, the auxiliary cooling mechanism is in the second position to cool the inner pot 13 together with the external air.

In another embodiment, the electric pressure cooker 100 further comprises a heat insulation mechanism disposed independently from the cooker body 10 and the cooker cover 20, and when the first connecting block 121 is unfolded, the heat insulation mechanism is wrapped outside the inner cooker 13 to prevent a user from touching the inner cooker 13 and being burned. Specifically, heat-proof mechanism is the network structure who has the fretwork hole, and the fretwork hole allows interior pot 13 of external gas flow to and interior pot 13 surface heat transfer, and network structure itself can prevent that pot 13 is scalded in the user direct contact.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
