[0013] In one embodiment, one end of the first connecting block is movably connected to the base and controllably slides relative to the base in a direction away from the inner pot, so that the other end of the first connecting block is separated from the pot cover to form the connecting port.

[0014] In one embodiment, the first connecting block can be rotated and unfolded relative to the base after being separated from the pot cover.

[0015] In one embodiment, the first connecting block can be rotated and unfolded relative to the base under the action of gravity.

[0016] In one embodiment, the first connecting block is a retractable member, and when the first connecting block is separated from the pot cover, the first connecting block can be controllably retracted.

[0018] In one embodiment, the movable member includes a sliding member and a rotating member, the sliding member is slidably disposed in the sliding groove, the rotating member is connected to the movable member, and the first connecting block is rotatably connected to the rotating member;

[0019] The sliding member can controllably slide in the sliding groove to drive the rotating member and the first connecting block to move in a direction away from the inner pot, and the first connecting block can rotate and unfold relative to the rotating member after being separated from the pot cover.

[0020] In one embodiment, the rotating member is a mounting tube, and a mounting hole is provided at one end of the first connecting block connected to the rotating member. The mounting tube is passed through the mounting hole. When the first connecting block is separated from the pot cover, the first connecting block can rotate in cooperation with the mounting tube through the mounting hole.

[0021] In one embodiment, the mounting tube includes a first semicircular tube and a second semicircular tube that are butt-jointed with each other, the sliding member includes at least two sliding members that are spaced apart from each other, the first semicircular tube is connected to a portion of the sliding member, and the second semicircular tube is connected to the remaining portion of the sliding member.

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See also Figure 1 An embodiment of the present invention provides an electric pressure cooker 100, comprising 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 between the cooker body 10 and the cooker cover 20.

[0037] See also Figure 2 Specifically, 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 connected to the base 11, and the other end extends in a direction away from the base 11 to define a receiving cavity with an opening between the outer pot 12 and the base 11. The inner pot 13 is received in the receiving cavity from the opening. The pot cover 20 covers the outer pot 12 and defines the above-mentioned cooking space between the inner pot 13. The base 11 is provided with a heating mechanism 112 to heat the food in the cooking space, and the pot cover 20 is provided with a pressure relief valve 21 to relieve the pressure in the cooking space.

[0038] The outer pot 12 is at least partially controllably separated from the pot cover 20 and / or the base 11 to form a communication port 50 (see FIG. 5 ) connecting the inner pot 13 with the outside. Figure 3 ).

[0039] Through the above arrangement, when the electric pressure cooker 100 finishes cooking, at least a portion of the outer pot 12 can be separated from the pot cover 20 and / or the base 11, thereby forming a connecting port 50 connecting the outside world and the inner pot 13. The outside gas flows to the inner pot 13 through the connecting port 50 and exchanges heat with the surface of the inner pot 13 (i.e., the entire indoor environment cools the inner pot 13). In this way, the temperature inside the inner pot 13 decreases. When the temperature inside the inner pot 13 decreases, the pressure inside the inner pot 13 decreases accordingly. When the pressure inside the inner pot 13 decreases, the time required for pressure release becomes shorter, saving the time required from the end of cooking to eating.

[0040] In one embodiment, a portion of the outer pot 12 is controllably separable from the pot cover 20 and / or the base 11. Specifically, the outer pot 12 includes at least two connecting blocks that are independently arranged from each other, and all the connecting blocks are connected to form the outer pot 12. Figure 4 and Figure 5 Part of the connection blocks are divided into first connection blocks 121, and the remaining connection blocks are divided into second connection blocks 122. The first connection blocks 121 are controllably separated from the pot cover 20 and / or the base 11, and the second connection blocks 122 are connected between the base 11 and the pot cover 20.

[0041] See also Figure 3 That is, when cooking is finished, the first connection block 121 can be separated from the pot cover 20 and / or the base 11 to form a connecting port 50 connecting the outside and the inner pot 13. The second connection block 122 is always connected between the base 11 and the pot cover 20 to prevent the pot cover 20 from being opened due to excessive pressure in the inner pot 13.

[0042] It is understandable that in other embodiments, the outer pot 12 can be completely separated from the pot cover 20 and / or the base 11. For example, in one embodiment, the outer pot 12 is completely controllably separated from the pot cover 20. When cooking is completed, the outer pot 12 can be completely separated from the pot cover 20. However, in this case, the electric pressure cooker 100 is required to further include a connecting mechanism. Before the outer pot 12 is completely separated from the pot cover 20, the connecting mechanism is controlled to be connected between the base 11 and the pot cover 20 to prevent the pot cover 20 from being washed open under the action of high pressure. In another embodiment, the outer pot 12 is completely separated from the base 11. When cooking is completed, the outer pot 12 can be completely separated from the base 11. In this case, the electric pressure cooker 100 is also required to further include a connecting mechanism. Before the outer pot 12 is completely separated from the base 11, the connecting mechanism is controlled to be connected between the base 11 and the pot cover 20 to prevent the pot cover 20 from being washed open under the action of high pressure. In another embodiment, the outer pot 12 may be completely separated from the lid 20 and the base 11. In this case, the electric pressure cooker 100 is also required to include a connecting mechanism. Before the outer pot 12 is completely separated from the lid 20 and the base 11, the connecting mechanism is controlled to be connected between the base 11 and the lid 20 to prevent the lid 20 from being blown open under the action of high pressure.

[0043] Specifically, the first connection 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 connection block 121 is separated from the pot cover 20 to form a communication port 50 .

[0044] Continue reading Figure 2 In one embodiment, the electric pressure cooker 100 further includes a movable member 30, a slide groove 111 is provided on the base 11, the movable member 30 is slidably disposed in the slide groove 111, the first connection block 121 is slidably connected to the base 11 through the movable member 30, the movable member 30 can be controlled to slide in the slide groove 111 to drive the first connection block 121 to move in a direction away from the inner pot 13, so that the outer pot 12 is separated from the pot cover 20. It is conceivable that in another embodiment, the electric pressure cooker 100 can also omit the movable member 30, the slide groove 111 is provided on the base 11, the first connection block 121 is directly slidably disposed in the slide groove 111, the first connection block 121 can be controlled to slide in the slide groove 111 to move in a direction away from the inner pot 13, so that the other end of the first connection block 121 is separated from the pot cover 20 to form a communication port 50.

[0045] 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. An operation panel 40 is provided on the base 1111, and the operation panel 40 is electrically connected to the control mechanism. When cooking is finished, the operation panel 40 can be operated to make the control mechanism control the driving mechanism to move, and the driving mechanism drives the movable member 30 to move in the slide groove 111, so as to drive the first connecting block 121 to move in a direction away from the inner pot 13.

[0046] In one embodiment, after the first connection block 121 is separated from the pot cover 20, it can rotate and unfold relative to the base 11. After the first connection block 121 is unfolded, the communication area of ​​the communication port 50 formed between it and the pot cover 20 increases, which can promote more external gas to enter from the communication port 50 to exchange heat with the outer surface of the inner pot 13. That is, the first connection block 121 and the second connection block 122 of the outer pot 12 of the electric pressure cooker 100 provided in this embodiment are similar to the petals of a flower. The first connection block 121 can be unfolded like a petal when it opens, while the second connection block 122 is always connected between the base 11 and the pot cover 20 (see Figure 3 ).

[0047] See also Figure 6 Specifically, the movable member 30 includes a sliding member 31 and a rotating member 32. The sliding member 31 is slidably disposed in the slide groove 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 can controllably slide in the slide groove 111 to drive the rotating member 32 and the first connecting block 121 to move in a direction away from the inner pot 13, and the first connecting block 121 can rotate and unfold relative to the rotating member 32 after being separated from the pot cover 20.

[0048] It is conceivable that in other embodiments, the electric pressure cooker 100 can omit the movable part 30, and instead a sliding groove and a rotating groove that are interconnected are provided on the base 11. When the first connecting block 121 slides from the sliding groove to the rotating groove, the first connecting block 121 is separated from the pot cover 20, and the first connecting block 121 rotates and unfolds in the rotating groove.

[0049] In a specific embodiment, the first connection block 121 can be rotated and unfolded relative to the rotating member 32 under the action of its own weight. That is, when the upper end of the first connection block 121 is free from the restriction of the pot cover 20, since the lower end of the first connection block 121 is rotatably connected to the rotating member 32, if the upper end of the first connection block 121 is heavier than the lower end, and the outer side of the upper end is heavier than the inner side, the first connection block 121 is lowered and unfolded under the action of gravity. It is conceivable that in other embodiments, the upper end of the first connection block 121 can be controlled by a control mechanism to be unfolded after being free from the restriction of the pot cover 20, which is not limited here.

[0050] Furthermore, the rotating member 32 is a mounting tube, and a mounting hole is provided at one end of the first connecting block 121 connected to the rotating member 32. The mounting tube is passed through the mounting hole. When the first connecting block 121 is separated from the pot cover 20, the first connecting block 121 can rotate in cooperation with the mounting tube through the mounting hole.

[0051] See also Figure 7 and Figure 8 Specifically, the mounting tube includes a first semicircular tube 321 and a second semicircular tube 322 that are arranged opposite to each other, and the sliding member 31 includes at least two that are spaced apart from each other, the first semicircular tube 321 is connected to a part of the sliding member 31, and the second semicircular tube 322 is connected to the remaining part of the sliding member 31. Part of the first connecting block 121 is rotatably connected to the first semicircular tube 321, and the remaining part of the first connecting block 121 is rotatably connected to the second semicircular tube 322, and the second connecting block 122 is connected to the joint between the first semicircular tube 321 and the second semicircular tube 322, and the position between the second connecting block 122 and the base 11 remains unchanged when the first semicircular tube 321 and the second semicircular tube 322 move.

[0052] That is, when cooking is finished, the control mechanism controls the sliding member 31 to move in the chute 111, and the first semicircular tube 321 and the second semicircular tube 322 that were originally connected are separated to form an ellipse. At this time, the upper end of the first connecting block 121 is separated from the pot cover 20. When the upper end of the first connecting block 121 is free from the restriction of the pot cover 20, it is unfolded under the action of gravity. Since the second connecting block 122 is connected to the joint between 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 (that is, after the circle changes to an ellipse, the diameter of the circle is equal to the minor axis of the formed ellipse), the separation of the first semicircular tube 321 and the second semicircular tube 322 will not affect the second connecting block 122, and the second connecting block 122 is still fixed between the base 11 and the pot cover 20.

[0053] Continue reading Figure 3 and Figure 5 In a specific embodiment, the first connection block 121 includes 6 blocks, and the second connection 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 connection blocks 121 can be driven to move in a direction away from the inner pot 13, and the first connection block 121 is unfolded when it moves to the upper end and separates from the pot cover 20. When the first semicircular tube 321 and the second semicircular tube 322 are separated from each other, the second connection block 122 does not move relative to the pot cover 20 and the base 11. It can be understood that in other embodiments, the first connection block 121 can also be set to include 4 blocks, and the second connection block 122 can also include 4 blocks, which is not limited here.

[0054] In addition, the first connection block 121 is configured as a retractable member, and when the first connection block 121 is separated from the pot cover 20, the first connection block 121 can be controllably retracted to reduce the indoor space occupied by the first connection block 121 after it is unfolded.

[0055] In one embodiment, the electric pressure cooker 100 further includes an auxiliary cooling mechanism (not shown), which is disposed on the base 11 and is used to auxiliary cool the inner pot 13. Specifically, the auxiliary cooling mechanism is filled with a coolant, and the coolant flows therein and exchanges heat with the surface of the inner pot 13, thereby reducing the temperature of the inner pot 13.

[0056] More specifically, the auxiliary cooling mechanism has a first position relative to the base 11, which is accommodated in the base 11, and a second position which is extended outside the base 11. The auxiliary cooling mechanism switches between the first position and the second position. During cooking, the auxiliary cooling mechanism is in the first position. After cooking, when 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.

[0057] In another embodiment, the electric pressure cooker 100 further includes a heat insulation mechanism that is independently provided from the pot body 10 and the pot cover 20. When the first connection block 121 is unfolded, the heat insulation mechanism is wrapped around the inner pot 13 to prevent the user from being scalded by touching the inner pot 13. Specifically, the heat insulation mechanism is a mesh structure with hollow holes, and the hollow holes allow external gas to flow to the inner pot 13 and exchange heat with the surface of the inner pot 13. The mesh structure itself can prevent the user from being scalded by directly touching the inner pot 13.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
