TECHNICAL FIELD
[0001] The utility model relates to the technical field of cooking utensils, in particular to a pot assembly, a heating assembly and a cooking utensil. BACKGROUND
[0002] At present, the cooking utensil includes an outer pot, an inner liner and a heating disc, the heating disc is arranged in the outer pot, the inner liner is placed on the heating disc, and then when the cooking utensil cooks food, the food in the inner liner is heated through the heating disc.
[0003] In the related art, in order to improve the heating uniformity of the heating disc on the inner liner, a heat transfer piece is arranged to transfer the heat of the heating disc to the sidewall of the inner liner, but due to the expansion and deformation of the inner liner during heating, a gap will appear between the inner liner and the heat transfer piece during the cooking process of the cooking utensil, thereby reducing the heat transfer efficiency between the heat transfer piece and the inner liner. SUMMARY
[0004] The utility model aims at least to solve one of the technical problems existing in the prior art or related art.
[0005] Therefore, the first aspect of the utility model provides a pot assembly.
[0006] The second aspect of the utility model provides a heating assembly.
[0007] The third aspect of the utility model provides a cooking utensil.
[0008] Therefore, the first aspect of the utility model provides a pot assembly, which comprises a first pot body, a heating disc, a second pot body and a heat transfer piece; the first pot body has a containing cavity with an opening on one side; the heating disc is arranged in the first pot body; the second pot body can be placed in the containing cavity and located on the heating disc, or the second pot body can be separated from the containing cavity; the heat transfer piece is arranged around the heating disc and extends towards the opening of the containing cavity, and the heat transfer piece can move relative to the heating disc; when the second pot body is placed in the containing cavity, the second pot body is in contact with the heat transfer piece, and the heat transfer piece is located at a first position; when the second pot body is separated from the containing cavity, the heat transfer piece is at a second position, and the second position is closer to the opening of the containing cavity than the first position.
[0009] The pot assembly provided in the application comprises a first pot body, a heating disc and a second pot body. The heating disc is arranged in the first pot body, and the second pot body can be placed in the first pot body. The heating disc can heat the second pot body. When the cooking appliance works, the food is placed in the second pot body, and the heating disc heats the second pot body, thereby realizing the cooking of the food in the second pot body. The pot assembly further comprises a heat transfer member. The heat transfer member is arranged around the heating disc and extends towards the opening of the containing cavity. When the heating disc heats the second pot body, the heat transfer member can transfer more heat from the heating disc to the second pot body, thereby improving the heating efficiency of the heating disc on the second pot body. Moreover, since the heat transfer member extends towards the opening of the containing cavity, the heat transfer member can transfer heat to the side wall of the second pot body, thereby improving the heating area of the second pot body, making the heating of each area of the second pot body more uniform, and thereby improving the heating effect of the heating disc on the second pot body.
[0010] When the second pot body is placed in the containing cavity, the second pot body is in contact with the heat transfer member, and the heat transfer member is in the first position. When the second pot body is separated from the containing cavity, the heat transfer member is in the second position, which is closer to the opening of the containing cavity relative to the first position. That is, when the second pot body is placed in the containing cavity and the second pot body is in contact with the heat transfer member, the heat transfer member moves away from the opening of the containing cavity under the driving force of the gravity of the second pot body, thereby enabling the heat transfer member to be in closer contact with the second pot body, and further improving the heat transfer efficiency between the heat transfer member and the second pot body. Moreover, since the heat transfer member moves from the second position to the first position under the driving force of the second pot body, and the heat transfer member returns to the second position when the second pot body is separated from the containing cavity, even if the second pot body and / or the heat transfer member expands and deforms to a certain extent during the heating of the second pot body by the heating disc, the second pot body can be in close contact with the heat transfer member, thereby reducing the gap between the second pot body and the heat transfer member, and improving the heat transfer efficiency between the heat transfer member and the inner container.
[0011] And since the heat transfer piece can move relative to the heating disc, the position of the heating disc will not be affected during the up and down movement of the heat transfer piece, which also enables the second pot body to be in closer contact with the heat transfer piece while improving the tightness of the contact between the second pot body and the heating disc, further improving the heating efficiency of the heating disc on the cooking utensil. Since the heat transfer piece can move relative to the heating disc, the heat transfer piece and the heating disc can also adapt to second pot bodies of various shapes, thereby improving the versatility of the heating disc and the heat transfer piece. Specifically, during the process of the second pot body entering the first pot body, the second pot body first contacts the heat transfer piece, then the second pot body pushes the heat transfer piece to move downward, and after the second pot body contacts the heating disc, the second pot body and the heat transfer piece stop moving. When the second pot body deforms, the heat transfer piece will automatically adjust its position relative to the heating disc as the second pot body deforms, thereby enabling the second pot body to be in closer contact with the heat transfer piece. For second pot bodies of different shapes placed in the receiving cavity, the heat transfer piece can also be in closer contact with the second pot body.
[0012] In addition, the pot assembly in the above technical solution provided by the utility model can also have the following additional technical features:
[0013] In some technical solutions of the utility model, optionally, the heat transfer piece comprises a heat transfer part and a contact part; the heat transfer part is arranged between the heating disc and the first pot body and extends to the side of the heating disc away from the second pot body; the contact part is connected with the heat transfer part, is arranged around the second pot body, and is in contact with the area of the second pot body not covered by the heating disc.
[0014] In this technical solution, the heat transfer piece comprises a heat transfer part, the heat transfer part is arranged between the heating disc and the first pot body and extends to the side of the heating disc away from the second pot body, so that the heat transfer part can perform heat transfer with the heating disc; and since the heat transfer part is arranged between the heating disc and the first pot body, the heat transfer part can block the heat generated by the heating disc from being transferred to the first pot body, thereby reducing the loss of the heat generated by the heating disc and improving the utilization rate of the heat generated by the heating disc. The heat transfer piece further comprises a contact part, the contact part is connected with the heat transfer part, is arranged around the second pot body, and is in contact with the area of the second pot body not covered by the heating disc, thereby enabling the heat generated by the heating disc to be transferred to more areas of the second pot body, which can further improve the heated area of the second pot body and further improve the uniformity of the heating of each area of the second pot body, effectively improving the heating effect of the heating disc on the second pot body.
[0015] Specifically, the heat transfer part can block the heat generated by the heating disc from being transmitted to the first pot body, i.e., the heat transfer part can block the heat generated by the heating disc from flowing in the radial direction of the heating disc. The heat transmitted in the radial direction of the heating disc can contact the heat transfer part, and then the heat transfer part is heated. Although the heat transfer part is heated, some heat can still be transmitted to the first pot body, but more heat transmitted in the radial direction of the heating disc can be transmitted to the second pot body through the heat transfer part and the contact part, thereby reducing energy loss.
[0016] In some technical solutions of the present application, the heat transfer part further comprises a connecting part connected to the side of the heat transfer part away from the contact part, extending to the center of the heating disc, and located on the side of the heating disc away from the second pot body, and the connecting part is used to support the heat transfer part.
[0017] In this technical solution, the heat transfer part further comprises a connecting part connected to the side of the heat transfer part away from the contact part, the connecting part is used to support the heat transfer part, thereby improving the stability of the heat transfer part. The connecting part extends to the center of the heating disc, and the connecting part is located on the side of the heating disc away from the second pot body. When the heat generated by the heating disc is transmitted to the bottom wall of the first pot body, the heat will contact the connecting part, the connecting part is heated, and then the heat is transmitted to the second pot body through the connecting part, the heat transfer part and the contact part, thereby reducing the loss of the heat generated by the heating disc and improving the utilization rate of the heat generated by the heating disc.
[0018] Further, the heat transfer part, the contact part and the connecting part are one-piece stamped metal parts, and the connecting part is a flange at the bottom of the heat transfer part.
[0019] The surface of the heat transfer part can be designed with a texture, or can be treated with surface spraying, oxidation, polishing or other treatments to enhance the heat transfer effect.
[0020] In some technical solutions of the present application, the pot assembly further comprises an elastic part abutting against the connecting part, and when the second pot body is placed in the accommodating cavity, the elastic part is in a compressed state or a stretched state.
[0021] In this technical solution, the elastic part abuts against the connecting part, and when the second pot body is placed in the accommodating cavity, the elastic part is in a compressed state or a stretched state. The elastic part in the compressed state or the stretched state can provide an elastic force to the connecting part, thereby driving the heat transfer part to contact the second pot body more closely.
[0022] Since the elastic force cannot overcome the gravity of the second pot body, when the second pot body is placed in the first pot body, the heat transfer part is driven to move to the first position. After the second pot body is taken out of the accommodating cavity, the heat transfer part loses the pressure from the second pot body. At this time, the elastic force provided by the elastic part overcomes the gravity of the heat transfer part, and drives the heat transfer part to move to the second position. When the second pot body is placed in the accommodating cavity again, the heat transfer part can be driven to the first position again.
[0023] Further, the elastic members are multiple, and the multiple elastic members are arranged along the circumference of the heating disc. When the second pot body is placed, since the shape of the matching part between the bottom of the second pot body and the upper surface of the heating disc is not conducive to the flat placement of the second pot body, the heat transfer member can automatically level the second pot body through the multiple elastic members, and thus the placement of the second pot body is more flat.
[0024] Specifically, the elastic member can be a spring, and the elastic member can also be a rubber ring or a silica gel ring.
[0025] In some technical solutions of the utility model, optionally, the pot assembly further comprises a first connecting piece, the first connecting piece is arranged through the elastic member and the connecting part, and is connected with the heating disc; the two ends of the elastic member are respectively abutted with the end of the connecting part and the first connecting piece, or the two ends of the elastic member are respectively connected with the connecting part and the heating disc.
[0026] In the technical solution, the first connecting piece is arranged through the elastic member and the connecting part, and is connected with the heating disc, thereby limiting the heat transfer member, and the movement of the heat transfer member between the first position and the second position is more stable. Furthermore, the first connecting piece is arranged through the elastic member, and the two ends of the elastic member are respectively abutted with the end of the connecting part and the first connecting piece, or the two ends of the elastic member are respectively connected with the connecting part and the heating disc, so that the expansion and contraction of the elastic member is more stable, and the stability of the movement of the heat transfer member between the first position and the second position is further improved. The heat transfer member is installed on the heating disc through the first connecting piece and the elastic member, which simplifies the installation structure of the heat transfer member and improves the assembly efficiency of the heat transfer member.

Furthermore, the heating disc is provided with the mounting column, the first connecting piece is arranged through the first through hole and is connected with the mounting column, heat can be transferred to the connecting part through the mounting column and the first connecting piece, and then is transferred to the second pot body through the heat transfer part and the contact part, thereby improving the heat transfer efficiency between the heating disc and the second pot body.
[0031] Specifically, the first connecting piece is a bolt or a screw, and the elastic piece is sleeved on the bolt or the screw and abuts against the head of the bolt or the screw.
[0032] The mounting column is provided with a threaded hole, and the bolt or the screw is screwed into the threaded hole.

[0035] In the technical solution, the second connecting piece is arranged through the elastic piece and the connecting part, and is connected with the heating disc, thereby limiting the heat transfer piece, so that the movement of the heat transfer piece between the first position and the second position is more stable. Moreover, the second connecting piece is arranged through the elastic piece, and the two ends of the elastic piece respectively abut against the connecting part and the bottom wall of the first pot body, so that the expansion and contraction of the elastic piece is also more stable, further improving the stability of the movement of the heat transfer piece between the first position and the second position. The heat transfer piece is installed on the bottom wall of the first pot body through the second connecting piece and the elastic piece, which simplifies the installation structure of the heat transfer piece and improves the assembly efficiency of the heat transfer piece.
[0036] In some technical solutions of the utility model, optionally, the connecting part and the heating disc have a gap therebetween.
[0037] In the technical solution, the connecting part and the heating disc have a gap therebetween, so that the heat transfer piece does not collide with the heating disc when reciprocating up and down, thereby improving the stability of the heating piece during movement.

[0039] In the technical solution, the distance between the connecting part and the heating disc is greater than 0 and less than or equal to 15 mm, so that the connecting part can be closer to the heating disc, thereby obtaining more heat and reducing heat loss, and the connecting part and the heating disc can have sufficient gap to confirm the movement of the heat transfer piece, so as to avoid the heat transfer piece being blocked during movement, further improving the tightness of the contact between the second pot body and the heat transfer piece.

[0048] Further, when the second pot body is not placed on the heating disc, in the vertical direction, the corresponding position of the heat transfer member (the outer side of the heating disc, the inner side of the heat transfer member) is higher than the heating disc.

[0092] In this embodiment, the pot assembly includes a first pot body 100, a heating disc 200 arranged in the first pot body 100, and a second pot body 300 capable of being placed in the first pot body 100 and heated by the heating disc 200; when the cooking appliance is in operation, food is placed in the second pot body 300, and the heating disc 200 heats the second pot body 300, thereby realizing the cooking of the food in the second pot body 300. The pot assembly further includes a heat transfer member 400 arranged around the heating disc 200 and extending toward the opening 120 of the containing cavity 110; when the heating disc 200 heats the second pot body 300, the heat transfer member 400 can transfer more heat from the heating disc 200 to the second pot body 300, thereby improving the heating efficiency of the heating disc 200 on the second pot body 300; and since the heat transfer member 400 extends toward the opening 120 of the containing cavity 110, the heat transfer member 400 can transfer heat to the sidewall of the second pot body 300, thereby improving the heating area of the second pot body 300 and making the heating of each area of the second pot body 300 more uniform, thereby improving the heating effect of the heating disc 200 on the second pot body 300.
[0093] And since the heat transfer piece 400 can move relative to the heating disc 200, the position of the heating disc 200 will not be affected during the up-and-down movement of the heat transfer piece 400, which also makes the second pot body 300 more closely contact the heat transfer piece 400 while improving the tightness of the contact between the second pot body 300 and the heating disc 200, further improving the heating efficiency of the heating disc 200 on the cooking utensil. Since the heat transfer piece 400 can move relative to the heating disc 200, the heat transfer piece 400 and the heating disc 200 can also adapt to second pot bodies 300 of various shapes, thereby improving the versatility of the heating disc 200 and the heat transfer piece 400. Specifically, during the process of the second pot body 300 entering the first pot body 100, the second pot body 300 first contacts the heat transfer piece 400, and then the second pot body 300 pushes the heat transfer piece 400 to move downward until the second pot body 300 contacts the heating disc 200, and the second pot body 300 and the heat transfer piece 400 stop moving. When the second pot body 300 deforms, the heat transfer piece 400 will automatically adjust its position relative to the heating disc 200 along with the deformation of the second pot body 300, thereby making the second pot body 300 more closely contact the heat transfer piece 400. For different shapes of the second pot body 300 placed in the accommodating cavity 110, the heat transfer piece 400 can also more closely contact the second pot body 300.
[0094] Specifically, the first pot body 100 can be a shell of the cooking utensil, or can be an outer pot arranged inside the shell of the cooking utensil.
[0095] The embodiment provides a pot assembly, in addition to the technical features of the above-mentioned embodiment, the embodiment further includes the following technical features.
[0096] As shown in Figure 5 and Figure 6 The heat transfer piece 400 includes a heat transfer part 410 and a contact part 420; the heat transfer part 410 is arranged between the heating disc 200 and the first pot body 100, and extends away from the side of the heating disc 200 away from the second pot body 300; the contact part 420 is connected with the heat transfer part 410, arranged around the second pot body 300, and contacts the area of the second pot body 300 not covered by the heating disc 200.
[0097] In this embodiment, the heat transfer piece 400 includes a heat transfer portion 410, which is arranged between the heating disc 200 and the first pot body 100 and extends away from the second pot body 300 to the side of the heating disc 200, so that the heat transfer portion 410 can transfer heat with the heating disc 200; and since the heat transfer portion 410 is arranged between the heating disc 200 and the first pot body 100, the heat transfer portion 410 can block the heat generated by the heating disc 200 from being transferred to the first pot body 100, thereby reducing the loss of heat generated by the heating disc 200 and improving the utilization rate of the heat generated by the heating disc 200. The heat transfer piece 400 further includes a contact portion 420 connected with the heat transfer portion 410, arranged around the second pot body 300, and in contact with the area of the second pot body 300 not covered by the heating disc 200, thereby enabling the heat generated by the heating disc 200 to be transferred to more areas of the second pot body 300, which can further improve the heating area of the second pot body 300 and further improve the uniformity of heating of each area of the second pot body 300, effectively improving the heating effect of the heating disc 200 on the second pot body 300.
[0098] Specifically, the heat transfer portion 410 can block the heat generated by the heating disc 200 from being transferred to the first pot body 100, i.e., the heat transfer portion 410 can block the heat generated by the heating disc 200 from being lost in the radial direction of the heating disc 200. The heat transferred in the radial direction of the heating disc 200 will contact the heat transfer portion 410, thereby causing the heat transfer portion 410 to heat up, although some heat will be transferred to the first pot body 100 after the heat transfer portion 410 heats up, more heat of the heat transferred in the radial direction of the heating disc 200 will be transferred to the second pot body 300 through the heat transfer portion 410 and the contact portion 420, thereby reducing energy loss.
[0099] The present embodiment provides a pot assembly, in addition to the technical features of the above-mentioned embodiments, the present embodiment further includes the following technical features.
[0100] As shown in Figure 5 and Figure 6 The heat transfer piece 400 further includes a connecting portion 430 connected with the heat transfer portion 410 away from the side of the contact portion 420, extending to the center of the heating disc 200, and the connecting portion 430 is located on the side of the heating disc 200 away from the second pot body 300, and the connecting portion 430 is used to support the heat transfer piece 400.
[0101] In this embodiment, the heat transfer piece 400 further comprises a connecting portion 430 connected to the heat transfer portion 410 on the side away from the contact portion 420, the connecting portion 430 is used to support the heat transfer piece 400, thereby improving the stability of the heat transfer piece 400. The connecting portion 430 extends to the center of the heating disc 200, and the connecting portion 430 is located on the side of the heating disc 200 away from the second pot body 300. When the heat generated by the heating disc 200 is transmitted to the bottom wall 130 of the first pot body 100, the heat will contact the connecting portion 430, the connecting portion 430 will be heated, and then the heat will be transmitted to the second pot body 300 by the connecting portion 430, the heat transfer portion 410 and the contact portion 420, thereby reducing the loss of heat generated by the heating disc 200 and improving the utilization rate of the heat generated by the heating disc 200.
[0102] Further, the heat transfer portion 410, the contact portion 420 and the connecting portion 430 are one-piece stamped metal parts, and the connecting portion 430 is a flange at the bottom of the heat transfer piece 400.
[0103] The surface of the heat transfer piece 400 can be designed with a texture, or can be treated with surface spraying, oxidation, polishing or other treatments to enhance the heat transfer effect.
[0104] The present embodiment provides a pot assembly, in addition to the technical features of the above-mentioned embodiments, the present embodiment further comprises the following technical features.
[0105] As shown in Figure 7 , Figure 8 and Figure 9 , the pot assembly further comprises an elastic member 500 abutting against the connecting portion 430, when the second pot body 300 is placed in the accommodating cavity 110, the elastic member 500 is in a compressed state or a stretched state.
[0106] In this embodiment, the elastic member 500 abuts against the connecting portion 430, when the second pot body 300 is placed in the accommodating cavity 110, the elastic member 500 is in a compressed state or a stretched state, the elastic member 500 in a compressed state or a stretched state will provide an elastic force to the connecting portion 430, thereby driving the heat transfer piece 400 to contact the second pot body 300 more closely.
[0107] Because the elastic force cannot overcome the gravity of the second pot body 300, when the second pot body 300 is placed in the first pot body 100, it will drive the heat transfer piece 400 to move to the first position, after the second pot body 300 is taken out of the accommodating cavity 110, the heat transfer piece 400 will lose the pressure from the second pot body 300, at this time the elastic force provided by the elastic member 500 overcomes the gravity of the heat transfer piece 400 itself, driving the heat transfer piece 400 to move to the second position, when the second pot body 300 is placed in the accommodating cavity 110 again, it can drive the heat transfer piece 400 to the first position again.
[0108] Further, the plurality of elastic members 500 are arranged along the circumferential direction of the heating disc 200 (indicated by the arrow H). When the second pot body 300 is placed, the heat transfer member 400 can automatically level the second pot body 300 through the plurality of elastic members 500, so that the second pot body 300 is placed more flatly, because the bottom of the second pot body 300 and the matching part on the upper surface of the heating disc 200 are not shaped to facilitate the flat placement of the second pot body 300. Figure 1 Further, the plurality of elastic members 500 are arranged along the circumferential direction of the heating disc 200 (indicated by the arrow H). When the second pot body 300 is placed, the heat transfer member 400 can automatically level the second pot body 300 through the plurality of elastic members 500, so that the second pot body 300 is placed more flatly, because the bottom of the second pot body 300 and the matching part on the upper surface of the heating disc 200 are not shaped to facilitate the flat placement of the second pot body 300.
[0109] Specifically, the elastic member 500 can be a spring, and the elastic member 500 can also be a rubber ring or a silica gel ring.

[0112] In this embodiment, the first connecting member 600 is arranged through the elastic member 500 and the connecting part 430, and is connected with the heating disc 200, thereby limiting the heat transfer member 400, so that the movement of the heat transfer member 400 between the first position and the second position is more stable. Moreover, the first connecting member 600 is arranged through the elastic member 500, and the two ends of the elastic member 500 are respectively abutted with the end of the first connecting member 600 and the connecting part 430, or the two ends of the elastic member 500 are respectively connected with the heating disc 200 and the connecting part 430, so that the stretching and contraction of the elastic member 500 is more stable, further improving the stability of the movement of the heat transfer member 400 between the first position and the second position. The heat transfer member 400 is installed on the heating disc 200 through the first connecting member 600 and the elastic member 500, which simplifies the installation structure of the heat transfer member 400 and improves the assembly efficiency of the heat transfer member 400.
[0113] Specifically, the two ends of the elastic member 500 are respectively abutted with the end of the first connecting member 600 and the connecting part 430, and the elastic member 500 is in a compressed state when the second pot body 300 is placed in the accommodating cavity 110.
[0114] The two ends of the elastic member 500 are respectively connected with the heating disc 200 and the connecting part 430, and the elastic member 500 is in a stretched state when the second pot body 300 is placed in the accommodating cavity 110.

In addition, the heating disc 200 is provided with the mounting column 210, the first connecting piece 600 is arranged through the first through hole 432 and connected with the mounting column 210, heat can be transferred to the connecting portion 430 through the mounting column 210 and the first connecting piece 600, and then transferred to the second pot body 300 through the heat transfer portion 410 and the contact portion 420, so that the heat transfer efficiency between the heating disc 200 and the second pot body 300 is further improved.
[0118] Specifically, the first connecting piece 600 is a bolt or a screw, and the elastic piece 500 is sleeved on the bolt or the screw and abuts against the head of the bolt or the screw.
[0119] The mounting column 210 is provided with a threaded hole, and the bolt or the screw is screwed in the threaded hole.
[0120] Specifically, the heating disc 200 is provided with two or more mounting columns 210, and the connecting portion 430 is provided with two or more first through holes 432.
[0121] The embodiment provides a pot assembly, and in addition to the technical features of the above embodiment, the embodiment further comprises the following technical features.

[0123] In this embodiment, the second connector 700 passes through the elastic member 500 and the connecting portion 430, and is connected to the heating plate 200, thereby limiting the movement of the heat transfer member 400 and making its movement between the first and second positions more stable. Furthermore, the second connector 700 passes through the elastic member 500, with both ends of the elastic member 500 abutting against the connecting portion 430 and the bottom wall 130 of the first pot body 100, respectively, making the expansion and contraction of the elastic member 500 more stable and further improving the stability of the movement of the heat transfer member 400 between the first and second positions. The heat transfer member 400 is installed on the bottom wall 130 of the first pot body 100 via the second connector 700 and the elastic member 500, simplifying the installation structure of the heat transfer member 400 and improving its assembly efficiency.
[0124] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0125] like Figure 6 As shown, there is a gap 220 between the connecting part 430 and the heating plate 200.
[0126] In this embodiment, there is a gap 220 between the connecting part 430 and the heating plate 200, so that the heat transfer element 400 will not collide with the heating plate 200 when it moves up and down, thereby improving the stability of the heating element during the movement.
[0127] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0129] In this embodiment, the distance L1 between the connecting part 430 and the heating plate 200 is greater than 0 and less than or equal to 15 mm. This allows the connecting part 430 to be closer to the heating plate 200, thereby obtaining more heat and reducing heat loss. It also ensures that there is a sufficient gap 220 between the connecting part 430 and the heating plate 200 to confirm the movement of the heat transfer element 400, preventing the heat transfer element 400 from being blocked during movement, and further improving the tightness of the contact between the second pot body 300 and the heat transfer element 400.
[0130] Specifically, the distance L1 between the connecting part 430 and the heating plate 200 is 5 mm.
[0131] The distance L1 between the connecting part 430 and the heating plate 200 is 8 mm.
[0132] The distance L1 between the connecting part 430 and the heating plate 200 is 10 mm.
[0133] The distance L1 between the connecting part 430 and the heating plate 200 is 15 mm.
[0134] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0136] In this embodiment, in the vertical direction of the pot assembly, the contact portion 420 extends in an arc shape. When the second pot body 300 is placed in the receiving cavity 110, the contact portion 420 fits against the arc-shaped portion 310, so that the shape of the contact portion 420 can match the arc-shaped portion 310 of the second pot body 300, thereby increasing the contact area between the contact portion 420 and the second pot body 300, and further improving the heat transfer efficiency between the second pot body 300 and the heat transfer element 400.
[0137] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0139] In this embodiment, in the vertical direction of the pot assembly, the side where the contact part 420 is connected to the heat transfer part 410 is higher than the heating plate 200. When the second pot body 300 is placed inside the first pot body 100, the second pot body 300 will first contact the contact part 420 and will move downward a certain distance, thereby ensuring that the second pot body 300 can have a closer contact with the heat transfer element 400.

[0157] In this embodiment, during the process that the second pot body 300 is placed on the heating disc 200, when the second pot body 300 contacts the heat transfer piece 400, the heat transfer piece 400 moves downward under the driving of the gravity of the second pot body 300, so that the heat transfer piece 400 can be in closer contact with the second pot body 300, further improving the heat transfer efficiency between the heat transfer piece 400 and the second pot body 300, and since the heat transfer piece 400 moves downward under the driving of the second pot body 300, and the heat transfer piece 400 will return to the original position when the second pot body 300 is separated from the heating disc 200, so during the process that the heating disc 200 heats the second pot body 300, even if the second pot body 300 and / or the heat transfer piece 400 produces certain expansion and deformation, the second pot body 300 can be in close contact with the heat transfer piece 400, reducing the gap between the second pot body 300 and the heat transfer piece 400, and further improving the heat transfer efficiency between the heat transfer piece 400 and the inner container.
