Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooking utensil technology, and more specifically, to a pot assembly and a cooking utensil. Background Technology
[0002] Currently, cooking appliances include an outer pot, an inner pot, and a heating plate. The heating plate is placed inside the outer pot, and the inner pot is placed on the heating plate. When cooking food, the food in the inner pot is heated by the heating plate.
[0003] In related technologies, in order to improve the uniformity of heating of the inner pot by the heating plate, a heat transfer element is set to transfer the heat of the heating plate to the side wall of the inner pot. However, since the heat transfer element will expand and deform during the heating process, a gap will appear between the inner pot and the heat transfer element during the cooking process, thereby reducing the heat transfer efficiency between the heat transfer element and the inner pot. Utility Model Content
[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the first aspect of this utility model proposes a pot assembly.
[0006] The second aspect of this utility model provides a cooking utensil.
[0007] In view of the above, the first aspect of the present invention provides a pot assembly, including a first pot body, a heating plate, a second pot body, and a heat transfer element; the first pot body has a receiving cavity with an opening on one side; the heating plate is disposed in the first pot body; the second pot body can be placed in the receiving cavity and located on the heating plate, or the second pot body can be detached from the receiving cavity; the heat transfer element is disposed around the heating plate and extends toward the opening of the receiving cavity, and the heating plate can move relative to the heat transfer element; wherein, when the second pot body is placed in the receiving cavity, the second pot body is in contact with the heating plate, and the heating plate is located in a first position; when the second pot body is detached from the receiving cavity, the heating plate is located in a second position, and the second position is closer to the opening of the receiving cavity than the first position.
[0008] The pot assembly provided in this application includes a first pot body, a heating plate, and a second pot body. The heating plate is disposed within the first pot body, and the second pot body can be placed within the first pot body. The heating plate heats the second pot body. When the cooking appliance is in operation, food is placed in the second pot body, and the heating plate heats the second pot body, thereby cooking the food in the second pot body. The pot assembly also includes a heat transfer element, which is disposed around the heating plate and extends into the opening of the receiving cavity. When the heating plate heats the second pot body, the heat transfer element can transfer more heat from the heating plate to the second pot body, thereby improving the heating efficiency of the heating plate on the second pot body. Furthermore, because the heat transfer element extends into the opening of the receiving cavity, it can transfer heat to the side wall of the second pot body, thereby increasing the heated area of the second pot body and making the heating of each area of the second pot body more uniform, thus improving the heating effect of the heating plate on the second pot body.
[0009] When the second pot is placed in the receiving cavity, it is in contact with the heat transfer element, and the heating plate is in the first position. When the second pot is removed from the receiving cavity, the heating plate is in the second position, which is closer to the opening of the receiving cavity than the first position. This means that during the process of placing the second pot in the receiving cavity, when the second pot is in contact with the heating plate, the heating plate moves away from the opening of the receiving cavity under the drive of the second pot's own gravity. This allows the heating plate and the heat transfer element to make closer contact with the second pot, further improving the heat transfer efficiency between the heating plate and the second pot. Furthermore, since the heating plate moves from the second position to the first position under the drive of the second pot, and returns to the second position when the second pot is removed from the receiving cavity, even if the second pot and / or the heat transfer element expand and deform to a certain extent during the heating process, the heating plate can still move to the position where the second pot and the heat transfer element are in close contact under the drive of the second pot. This ensures close contact between the second pot and the heat transfer element, reduces the gap between them, and further improves the heat transfer efficiency between them.
[0010] Furthermore, because the heating plate can move relative to the heat transfer element, the position of the heat transfer element is not affected during the up-and-down movement of the heating plate. This allows the second pot to have a closer contact with the heat transfer element, while also improving the tightness of the contact between the second pot and the heating plate, further enhancing the heating efficiency of the cooking appliance. The ability of the heating plate to move relative to the heat transfer element also allows both the heat transfer element and the heating plate to be adapted to various shapes of second pots, thus improving the versatility of both the heating plate and the heat transfer element.
[0011] In addition, the pot assembly in the above-mentioned technical solution provided by this utility model may also have the following additional technical features:
[0012] Optionally, in some technical solutions of this utility model, the pot assembly includes a first elastic member, one end of which abuts against the heating plate and the other end of which abuts against the bottom wall of the first pot body. When the heating plate is in the first position, the first elastic member is in a compressed state.
[0013] In this technical solution, one end of the first elastic member abuts against the heating plate, and the other end abuts against the bottom wall of the first pot body. When the second pot body is placed in the receiving cavity, the first elastic member is in a compressed state. The first elastic member in a compressed state will provide elastic force to the heating plate, thereby making the contact between the heating plate and the second pot body more compact.
[0014] Since the elastic force of the first elastic element cannot overcome the weight of the second pot, when the second pot is placed inside the first pot, it will drive the heating plate to move to the first position. After the second pot is removed from the receiving cavity, the heating plate will lose the pressure from the second pot. At this time, the elastic force provided by the first elastic element will overcome the weight of the heating plate itself and drive the heating plate to move to the second position. When the second pot is placed back into the receiving cavity, it can drive the heating plate to the first position again.
[0015] Optionally, in some technical solutions of this utility model, the pot assembly further includes a first connecting member, which passes through the first pot body and the first elastic member and is connected to the heating plate.
[0016] In this technical solution, the first connecting member passes through the first pot body and the first elastic member, and is connected to the heating plate, thereby limiting the movement of the heating plate and making its movement between the first and second positions more stable. Furthermore, the first connecting member passes through the first elastic member, with both ends of the first elastic member abutting against the heating plate and the first pot body respectively, making the extension and contraction of the first elastic member more stable, further improving the stability of the heating plate's movement between the first and second positions. The heating plate is installed on the first pot body via the first connecting member and the first elastic member, simplifying the installation structure of the heating plate and improving its assembly efficiency.
[0017] Optionally, in some technical solutions of this utility model, the heating plate is provided with a mounting post, and the first elastic member is sleeved on the mounting post; the bottom wall of the first pot body is provided with a first through hole, which is opposite to the mounting post; the first connecting member passes through the first through hole and is connected to the mounting post.
[0018] In this technical solution, the heating plate and the first pot body are respectively provided with opposite mounting posts and first through holes. The first connector passes through the first through hole and is connected to the mounting post, making the assembly process of the heat transfer component simpler and more convenient.
[0019] In some technical solutions of this utility model, optionally, the heat transfer element includes a heat transfer part and a contact part; the heat transfer part is disposed between the heating plate and the first pot body, and extends to the side of the heating plate away from the second pot body; the contact part is connected to the heat transfer part, arranged around the second pot body, and contacts the area of the second pot body not covered by the heating plate.
[0020] In this technical solution, the heat transfer component includes a heat transfer section disposed between the heating plate and the first pot body, extending towards the side of the heating plate away from the second pot body, enabling heat transfer between the heat transfer section and the heating plate. Furthermore, because the heat transfer section is disposed between the heating plate and the first pot body, it can prevent the heat generated by the heating plate from being transferred to the first pot body, thereby reducing heat loss and improving the utilization rate of the heat generated by the heating plate. The heat transfer component also includes a contact section connected to the heat transfer section, arranged around the second pot body, and in contact with the area of the second pot body not covered by the heating plate. This allows the heat generated by the heating plate to be transferred to more areas of the second pot body, further increasing the heated area of the second pot body and improving the uniformity of heating in different areas of the second pot body, effectively enhancing the heating effect of the heating plate on the second pot body.
[0021] In some technical solutions of this utility model, optionally, the heat transfer part includes a bending part, which is arranged along the bottom wall of the heating plate. When the heating plate is in the first position, at least part of the heating plate is in contact with the bending part.
[0022] In this technical solution, the bent portion is arranged along the bottom wall of the heating plate. When the heating plate is in the first position, at least a portion of the heating plate is in contact with the bent portion. When the cooking appliance is working, the contact between the heating plate and the bent portion enables faster heat transfer between the heating plate and the bent portion, thereby accelerating the heat transfer between the heating plate and the heat transfer component and further improving the utilization rate of the heat generated by the heating plate.
[0023] During the operation of a cooking appliance, even if the heat transfer component deforms due to heat, the heating plate can move relative to the heat transfer component. Therefore, the heating plate can automatically adjust its position according to the deformation of the heat transfer component, so that the heating plate is at least partially in contact with the bent part, thereby further improving the utilization rate of the heat generated by the heating plate.
[0024] Furthermore, during operation, even if the cooking appliance is placed on an inclined countertop or tilted due to support from foreign objects, the heating plate can automatically adjust its position according to the tilt angle of the cooking appliance because it can move relative to the heat transfer components. This allows the heating plate to at least partially contact the bent part, further improving the utilization rate of the heat generated by the heating plate.
[0025] Optionally, in some technical solutions of this utility model, the bent portion is annular and arranged along the circumference of the heating plate.
[0026] In this technical solution, the bending part is ring-shaped and arranged around the circumference of the heating plate, so that the bending part is more evenly distributed at the bottom of the heating plate, thereby improving the uniformity of heat transfer between the heat transfer component and the heating plate.
[0027] In some technical solutions of this utility model, optionally, the contact portion is arranged at an angle relative to the height direction of the pot assembly from the side near the opening of the receiving cavity to the side connected to the heat transfer portion.
[0028] In this technical solution, the contact part is arranged at an angle relative to the height of the pot assembly. After the second pot body is placed in the receiving cavity, it automatically matches the contact part according to the position of the second pot body, thereby further improving the tightness of the contact between the contact part and the second pot body.
[0029] In some technical solutions of this utility model, optionally, the heat transfer component further includes a connecting part, which is connected to the side of the heat transfer component away from the contact part, extends toward the center of the heating plate, and is located on the side of the heating plate away from the second pot body. The connecting part is used to support the heat transfer component.
[0030] In this technical solution, the heat transfer component also includes a connecting portion, which connects to the side of the heat transfer component away from the contact portion. The connecting portion supports the heat transfer component, thereby improving its stability. The connecting portion extends towards the center of the heating plate and is located on the side of the heating plate away from the second pot body. When the heat generated by the heating plate is transferred to the bottom wall of the first pot body, the heat will come into contact with the connecting portion, causing the connecting portion to heat up. The heat is then transferred to the second pot body through the connecting portion, the heat transfer portion, and the contact portion, thereby reducing the heat loss generated by the heating plate and improving the utilization rate of the heat generated by the heating plate.
[0031] Optionally, in some technical solutions of this utility model, there is a gap between the connecting part and the heating plate.
[0032] In this technical solution, there is a gap between the connecting part and the heating plate, so that the heat transfer element will not collide with the heating plate when it moves up and down, thereby improving the stability of the heating plate during the movement.
[0033] In some technical solutions of this utility model, optionally, the distance between the connecting part and the heating plate is greater than 0 and less than or equal to 15 mm.
[0034] In this technical solution, the distance between the connecting part and the heating plate is greater than 0 and less than or equal to 15 mm. This allows the connecting part to be closer to the heating plate, thereby obtaining more heat and reducing heat loss. It also ensures that there is a sufficient gap between the connecting part and the heating plate to confirm the movement of the heat transfer element, preventing the heat transfer element from being blocked during movement, and further improving the tightness of the contact between the second pot body and the heat transfer element.
[0035] Optionally, in some technical solutions of this utility model, when the second pot body is separated from the receiving cavity, the side where the contact part is connected to the heat transfer part is lower than the heating plate in the height direction of the pot assembly.
[0036] In this technical solution, in the height direction of the pot assembly, the side where the contact part is connected to the heat transfer part is lower than the heating plate. When the second pot body is placed inside the first pot body, the second pot body will first contact the heating plate and will move downward a certain distance, thereby ensuring that the second pot body can have a closer contact with the heat transfer element.
[0037] Optionally, in some technical solutions of this utility model, the second pot body includes an arc-shaped portion; in the height direction of the pot assembly, the contact portion extends in an arc shape, and when the second pot body is placed in the receiving cavity, the contact portion fits against the arc-shaped portion.
[0038] In this technical solution, the contact portion extends in an arc shape along the height direction of the pot assembly. When the second pot body is placed in the receiving cavity, the contact portion fits into the arc shape, so that the shape of the contact portion can match the arc shape of the second pot body, thereby increasing the contact area between the contact portion and the second pot body, and further improving the heat transfer efficiency between the second pot body and the heat transfer component.
[0039] In some technical solutions of this utility model, optionally, the heating plate is provided with a guide post, the first pot body is provided with a second through hole, and the guide post passes through the second through hole.
[0040] In this technical solution, the guide post passes through the second through hole to guide the movement of the heating plate and further improve the stability of the heating plate during its movement.
[0041] In some technical solutions of this utility model, optionally, the distance between the first position and the second position is greater than 0 and less than or equal to 10 mm.
[0042] In this technical solution, the distance between the first position and the second position is greater than 0 and less than or equal to 10 mm, which enables the heat transfer element to adapt to arc-shaped parts with different curvatures, further improving the second pot body model or type that the heat transfer element can adapt to.

Detailed Implementation
[0054] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0055] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0056] The following reference Figures 1 to 7 This invention describes pot assemblies and cooking utensils according to some embodiments of the present invention.
[0057] In one embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a pot assembly is provided, including a first pot body 100, a heating plate 200, a second pot body 300, and a heat transfer element 400; the first pot body 100 has a receiving cavity 110 with an opening 120 on one side; the heating plate 200 is disposed within the first pot body 100; the second pot body 300 can be placed within the receiving cavity 110 and located on the heating plate 200, or the second pot body 300 can be detached from the receiving cavity 110; the heat transfer element 400 is disposed around the heating plate 200 and extends toward the opening 120 of the receiving cavity 110, and the heating plate 200 is movable relative to the heat transfer element 400; wherein, as Figure 1 , Figure 2 and Figure 3 As shown, when the second pot body 300 is placed in the receiving cavity 110, the second pot body 300 is in contact with the heating plate 200, as... Figure 4 As shown, the heating plate 200 is in the first position. Figure 4 (The position indicated by the middle arrow E); as Figure 5 , Figure 6 and Figure 7 As shown, when the second pot body 300 detaches from the receiving cavity 110, as Figure 4 As shown, the heating plate 200 is in the second position. Figure 4 (As indicated by the middle arrow F), the second position is closer to the opening 120 of the receiving cavity 110 than the first position.
[0058] In this embodiment, the pot assembly includes a first pot body 100, a heating plate 200, and a second pot body 300. The heating plate 200 is disposed inside the first pot body 100, and the second pot body 300 can be placed inside the first pot body 100. The heating plate 200 can heat the second pot body 300. When the cooking appliance is working, the food is placed inside the second pot body 300, and the heating plate 200 heats the second pot body 300, thereby realizing the cooking of the food inside the second pot body 300. The pot assembly also includes a heat transfer element 400, which is arranged around the heating plate 200 and extends into the opening 120 of the receiving cavity 110. When the heating plate 200 heats the second pot body 300, the heat transfer element 400 can transfer more heat from the heating plate 200 to the second pot body 300, thereby improving the heating efficiency of the heating plate 200 on the second pot body 300. Furthermore, since the heat transfer element 400 extends into the opening 120 of the receiving cavity 110, it can transfer heat to the side wall of the second pot body 300, thereby increasing the heated 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 plate 200 on the second pot body 300.
[0059] When the second pot body 300 is placed in the receiving cavity 110, it is in contact with the heat transfer element 400, and the heating plate 200 is in the first position. When the second pot body 300 is removed from the receiving cavity 110, the heating plate 200 is in the second position, which is closer to the opening 120 of the receiving cavity 110 than the first position. This means that during the process of placing the second pot body 300 in the receiving cavity 110, when the second pot body 300 contacts the heating plate 200, the heating plate 200 moves away from the opening 120 of the receiving cavity 110 under the force of its own weight. This allows the heating plate 200 and the heat transfer element 400 to have a closer contact with the second pot body 300, further improving the contact between the heating plate 200 and the second pot body 300. The heating plate 200 moves from the second position to the first position under the drive of the second pot body 300, and returns to the second position when the second pot body 300 leaves the receiving cavity 110. Therefore, during the process of heating the second pot body 300 by the heating plate 200, even if the second pot body 300 and / or the heat transfer element 400 expand and deform to a certain extent, the heating plate 200 can still move to the position where the second pot body 300 and the heat transfer element 400 are in close contact under the drive of the second pot body 300, thereby making the second pot body 300 and the heat transfer element 400 in close contact, reducing the gap 220 between the second pot body 300 and the heat transfer element 400, and thus improving the heat transfer efficiency between the heat transfer element 400 and the second pot body 300.
[0060] Furthermore, because the heating plate 200 can move relative to the heat transfer element 400, the position of the heat transfer element 400 is not affected during the up-and-down movement of the heating plate 200. This allows the second pot body 300 to have a tighter contact with the heat transfer element 400, while also improving the tightness of the contact between the second pot body 300 and the heating plate 200, further enhancing the heating efficiency of the heating plate 200 for the cooking appliance. Since the heating plate 200 can move relative to the heat transfer element 400, both the heat transfer element 400 and the heating plate 200 can be adapted to various shapes of second pot bodies 300, thereby improving the versatility of the heating plate 200 and the heat transfer element 400.
[0061] Specifically, during the process of the second pot body 300 entering the first pot body 100, the second pot body 300 first contacts the heating plate 200, and then the second pot body 300 pushes the heating plate 200 downwards until the second pot body 300 contacts the heat transfer element 400, at which point the second pot body 300 and the heating plate 200 stop moving. When the second pot body 300 or the heat transfer element 400 deforms, the heating plate 200 will automatically adjust its position relative to the heat transfer element 400 according to the deformation of the second pot body 300 and / or the heat transfer element 400, thereby making the contact between the second pot body 300 and the heat transfer element 400 tighter. When the second pot body 300 of different shapes is placed into the receiving cavity 110, the heat transfer element 400 can also make a tighter contact with the second pot body 300.
[0062] Furthermore, the heat transfer element 400 can be a single sheet metal part arranged in a ring, or it can be one or more heat transfer plates.
[0063] Specifically, the first pot body 100 can be the outer shell of a cooking utensil or an outer pot disposed inside the outer shell of the cooking utensil. The second pot body 300 is an inner pot or inner liner.
[0064] Specifically, the heat transfer element 400 is located below the maximum circumferential portion of the second pot body 300.
[0065] Specifically, the heat transfer component 400 is fastened to the upper surface of the bottom wall 130 of the first pot body 100 by means of screws, bent tongue-shaped structure fastening, welding, etc.
[0066] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0067] like Figure 2 and Figure 3 As shown, the pot assembly includes a first elastic member 500. One end of the first elastic member 500 abuts against the heating plate 200, and the other end abuts against the bottom wall 130 of the first pot body 100. When the heating plate 200 is in the first position, the first elastic member 500 is in a compressed state.
[0068] In this embodiment, one end of the first elastic member 500 abuts against the heating plate 200, and the other end abuts against the bottom wall 130 of the first pot body 100. When the second pot body 300 is placed in the receiving cavity 110, the first elastic member 500 is in a compressed state. The first elastic member 500 in the compressed state will provide elasticity to the heating plate 200, thereby making the contact between the heating plate 200 and the second pot body 300 more compact.
[0069] Since the elastic force of the first elastic element 500 cannot overcome the gravity of the second pot body 300, when the second pot body 300 is placed inside the first pot body 100, it will drive the heating plate 200 to move to the first position. After the second pot body 300 is removed from the receiving cavity 110, the heating plate 200 will lose the pressure from the second pot body 300. At this time, the elastic force provided by the first elastic element 500 overcomes the gravity of the heating plate 200 itself and drives the heating plate 200 to move to the second position. When the second pot body 300 is placed back into the receiving cavity 110, it can drive the heating plate 200 back to the first position.
[0070] Furthermore, there are multiple first elastic elements 500, and the multiple first elastic elements 500 are arranged along the circumference of the heating plate 200. Figure 1 Arranged in the direction indicated by the middle arrow H), when the second pot body 300 is placed, since the shape of the matching part between the bottom of the second pot body 300 and the inner wall of the heat transfer element 400 is not conducive to the flat placement of the second pot body 300, the heating plate 200 can achieve close contact with the second pot body 300 through multiple first elastic elements 500, thereby making the second pot body 300 more flat.
[0071] Furthermore, during the operation of the cooking appliance, the heat transfer element 400 will undergo thermal deformation, which may cause poor contact between the second pot body 300 and the heating plate 200. By providing the first elastic element 500, when the heating plate 200 and the second pot body 300 come into contact, there is always a tendency for them to be in pre-tight contact with each other. This can eliminate the phenomenon of poor contact caused by the expansion of the heating plate 200 or the second pot body 300, and keep them in a state of tight contact at all times.
[0072] Specifically, the first elastic element 500 can be a spring, or it can be a rubber ring or a silicone ring.
[0073] Furthermore, the pot assembly also includes a second elastic member and a second connecting member. The second elastic member abuts against the connecting portion 430, and when the second pot body 300 is placed in the receiving cavity 110, the second elastic member is in a compressed or stretched state. The second connecting member passes through the second elastic member and the connecting portion 430, and is connected to the heating plate 200; both ends of the second elastic member abut against the connecting portion 430 and the end of the second connecting member, respectively, or both ends of the second elastic member are connected to the connecting portion 430 and the heating plate 200, respectively. This allows the heat transfer member 400 to move relative to the heating plate 200.
[0074] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0075] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the pot assembly also includes a first connector 600, which passes through the first pot body 100 and the first elastic member 500 and is connected to the heating plate 200.
[0076] In this embodiment, the first connecting member 600 passes through the first pot body 100 and the first elastic member 500, and is connected to the heating plate 200, thereby limiting the movement of the heating plate 200 between the first and second positions. Furthermore, the first connecting member 600 passes through the first elastic member 500, with both ends of the first elastic member 500 abutting against the heating plate 200 and the first pot body 100 respectively, making the extension and contraction of the first elastic member 500 more stable, further improving the stability of the movement of the heating plate 200 between the first and second positions. The heating plate 200 is installed on the first pot body 100 via the first connecting member 600 and the first elastic member 500, simplifying the installation structure of the heating plate 200 and improving the assembly efficiency of the heating plate 200.
[0077] Specifically, the end of the first connector 600 is engaged with the bottom wall 130 of the first pot body 100 on the side away from the heating plate 200. When the heating plate 200 is in the first position, there is a gap 220 between the end of the first connector 600 and the bottom wall 130 of the first pot body 100. When the heating plate 200 is in the second position, the end of the first connector 600 is in contact with the bottom wall 130 of the first pot body 100.
[0078] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0079] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the heating plate 200 is provided with a mounting post 210, and the first elastic member 500 is sleeved on the mounting post 210; the bottom wall 130 of the first pot body 100 is provided with a first through hole 140, which is opposite to the mounting post 210; the first connector 600 passes through the first through hole 140 and is connected to the mounting post 210.
[0080] In this embodiment, the heating plate 200 and the first pot body 100 are respectively provided with opposite mounting posts 210 and first through holes 140. The first connector 600 passes through the first through hole 140 and is connected to the mounting post 210, making the assembly process of the heat transfer component 400 simpler and more convenient.
[0081] Specifically, the first connecting member 600 is a bolt or screw, and the first elastic member 500 is sleeved on the bolt or screw and abuts against the head of the bolt or screw.
[0082] The mounting post 210 is provided with threaded holes, into which bolts or screws are tightened.
[0083] Specifically, the heating plate 200 is provided with two or more mounting posts 210, and the first pot body 100 is provided with two or more first through holes 140.
[0084] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0085] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the heat transfer element 400 includes a heat transfer portion 410 and a contact portion 420; the heat transfer portion 410 is disposed between the heating plate 200 and the first pot body 100, and extends toward the side of the heating plate 200 away from the second pot body 300; the contact portion 420 is connected to the heat transfer portion 410, arranged around the second pot body 300, and contacts the area of the second pot body 300 not covered by the heating plate 200.
[0086] In this embodiment, the heat transfer element 400 includes a heat transfer section 410, which is disposed between the heating plate 200 and the first pot body 100 and extends toward the side of the heating plate 200 away from the second pot body 300, so that the heat transfer section 410 can transfer heat with the heating plate 200; and since the heat transfer section 410 is disposed between the heating plate 200 and the first pot body 100, the heat transfer section 410 can block the heat generated by the heating plate 200 from being transferred to the first pot body 100, thereby reducing the loss of heat generated by the heating plate 200 and improving the utilization rate of the heat generated by the heating plate 200. The heat transfer element 400 also includes a contact portion 420, which is connected to the heat transfer portion 410 and arranged around the second pot body 300. It contacts the area of the second pot body 300 that is not covered by the heating plate 200, thereby allowing the heat generated by the heating plate 200 to be transferred to more areas of the second pot body 300. This not only further increases the heated area of the second pot body 300, but also further improves the uniformity of heating in various areas of the second pot body 300, effectively improving the heating effect of the heating plate 200 on the second pot body 300.
[0087] Specifically, the heat transfer part 410 can prevent the heat generated by the heating plate 200 from being transferred to the first pot body 100, that is, the heat transfer part 410 can prevent the heat generated by the heating plate 200 from being lost radially along the heating plate 200. The heat transferred radially along the heating plate 200 will come into contact with the heat transfer part 410, thereby causing the heat transfer part 410 to heat up. Although some heat will be transferred to the first pot body 100 after the heat transfer part 410 heats up, more of the heat transferred radially along the heating plate 200 will be transferred to the second pot body 300 through the heat transfer part 410 and the contact part 420, thereby reducing energy loss.
[0088] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0089] like Figure 3 and Figure 7 As shown, the heat transfer section 410 includes a bending section 412, which is arranged along the bottom wall of the heating plate 200. When the heating plate 200 is in the first position, at least a portion of the heating plate 200 is in contact with the bending section 412.
[0090] In this embodiment, the bent portion 412 is arranged along the bottom wall of the heating plate 200. When the heating plate 200 is in the first position, at least a portion of the heating plate 200 is in contact with the bent portion 412. When the cooking appliance is in operation, the contact between the heating plate 200 and the bent portion 412 enables a faster heat transfer efficiency between the heating plate 200 and the bent portion 412, thereby accelerating the heat transfer between the heating plate 200 and the heat transfer element 400, and further improving the utilization rate of the heat generated by the heating plate 200.
[0091] During the operation of the cooking appliance, even if the heat transfer element 400 deforms due to heat, the heating plate 200 can move relative to the heat transfer element 400. Therefore, the heating plate 200 can automatically adjust its position according to the deformation of the heat transfer element 400, thereby making the heating plate 200 at least partially in contact with the bent part 412, further improving the utilization rate of the heat generated by the heating plate 200.
[0092] Furthermore, during the operation of the cooking appliance, even if the cooking appliance is placed on an inclined countertop or tilted due to the support of foreign objects at the bottom, the heating plate 200 can move relative to the heat transfer element 400. Therefore, the heating plate 200 can automatically adjust its position according to the tilt angle of the cooking appliance, thereby making the heating plate 200 at least partially in contact with the bent part 412, further improving the utilization rate of the heat generated by the heating plate 200.
[0093] Specifically, when the second pot 300 is not placed, the heat transfer element 400 has a step on its inner side, namely the bend 412, and the upper part of the step does not contact the lower outer part of the heating plate 200. When the second pot 300 is placed, the heat transfer element 400 has a step on its inner side, and the upper part of the step contacts the lower outer part of the heating plate 200. The contact can be partial or circumferential. Simultaneously, with this contact between the heat transfer element 400 and the heating plate 200, if the heating plate 200 or the second pot 300 expands and causes poor contact, affecting heat transfer efficiency, the heating plate 200 transfers heat to the heat transfer element 400 through this contact area, and the heat transfer element 400 transfers heat to the second pot 300. This reduces the inefficiently utilized heat radiated into space by the heating plate 200 due to poor contact.
[0094] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0095] like Figure 3 and Figure 7 As shown, the bent portion 412 is annular and arranged around the circumference of the heating plate 200.
[0096] In this embodiment, the bending portion 412 is annular and arranged around the circumference of the heating plate 200, so that the bending portion 412 is more evenly distributed on the bottom of the heating plate 200, thereby improving the uniformity of heat transfer between the heat transfer element 400 and the heating plate 200.
[0097] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0098] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the contact portion 420 extends from the side near the opening 120 of the receiving cavity 110 to the side connected to the heat transfer portion 410 in the height direction relative to the pot assembly. Figure 2 (In the direction indicated by the middle arrow G) arranged at an angle.
[0099] In this embodiment, the contact portion 420 is arranged at an angle relative to the height direction of the pot assembly. After the second pot body 300 is placed in the receiving cavity 110, it automatically matches the contact portion 420 according to the position of the second pot body 300, thereby further improving the tightness of the contact between the contact portion 420 and the second pot body 300.
[0100] Specifically, when placing the second pot body 300, since the shape of the matching part between the bottom of the second pot body 300 and the upper surface of the heating plate 200 is not conducive to the flat placement of the second pot body 300, the tilting arc of the first elastic member 500 and the heat transfer member 400 towards the center is used to make the second pot body 300 automatically flat.
[0101] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0102] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the heat transfer element 400 also includes a connecting portion 430, which is connected to the side of the heat transfer element 410 away from the contact portion 420 and extends toward the center of the heating plate 200. The connecting portion 430 is located on the side of the heating plate 200 away from the second pot body 300 and is used to support the heat transfer element 400.
[0103] In this embodiment, the heat transfer element 400 further includes a connecting portion 430, which is connected to the side of the heat transfer element 410 away from the contact portion 420. The connecting portion 430 is used to support the heat transfer element 400, thereby improving the stability of the heat transfer element 400. The connecting portion 430 extends towards the center of the heating plate 200 and is located on the side of the heating plate 200 away from the second pot body 300. When the heat generated by the heating plate 200 is transferred to the bottom wall 130 of the first pot body 100, the heat will come into contact with the connecting portion 430, causing the connecting portion 430 to heat up. The heat is then transferred to the second pot body 300 through the connecting portion 430, the heat transfer element 410, and the contact portion 420, thereby reducing the loss of heat generated by the heating plate 200 and improving the utilization rate of the heat generated by the heating plate 200.
[0104] Furthermore, the heat transfer part 410, the contact part 420 and the connecting part 430 are integrally stamped sheet metal parts, and the connecting part 430 is the flange at the bottom of the heat transfer part 400.
[0105] The surface of the heat transfer component 400 can be textured, or it can be treated with surface spraying, oxidation, smoothing, or other treatments to enhance the heat transfer effect.
[0106] Furthermore, the connecting part 430 is provided with a clearance space, in which the mounting post 210, the first connecting member 600 and the first elastic member 500 are all located. This can prevent the connecting part 430 from interfering with the movement of the heating plate 200, and also allow the connecting part 430 to cover a larger area of the bottom of the heating plate 200, thereby more effectively blocking the heat generated by the heating plate 200 from being transferred to the bottom wall 130 of the first pot body 100.
[0107] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0108] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, there is a gap 220 between the connecting part 430 and the heating plate 200.
[0109] 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 plate 200 during the movement.
[0110] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0111] like Figure 6 As shown, 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.
[0112] 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.
[0113] Specifically, the distance L1 between the connecting part 430 and the heating plate 200 is 5 mm.
[0114] The distance L1 between the connecting part 430 and the heating plate 200 is 8 mm.
[0115] The distance L1 between the connecting part 430 and the heating plate 200 is 10 mm.
[0116] The distance L1 between the connecting part 430 and the heating plate 200 is 15 mm.
[0117] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0118] like Figure 6 As shown, when the second pot body 300 detaches from the receiving cavity 110, on the side where the contact portion 420 is connected to the heat transfer portion 410 in the height direction of the pot assembly ( Figure 6 The position indicated by the middle arrow I) is 200 degrees below the heating plate.
[0119] In this embodiment, in the height direction of the pot assembly, the side where the contact part 420 is connected to the heat transfer part 410 is lower 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 heating plate 200 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.
[0120] Furthermore, when the second pot body 300 is not placed on the heating plate 200, in the height direction, the corresponding position of the heat transfer element 400 (outer side of the heating plate 200, inner side of the heat transfer element 400) is lower than the heating plate 200.
[0121] This embodiment provides a pot assembly, which, in addition to the technical features of the above embodiments, further includes the following technical features.
[0122] like Figure 2 and Figure 6 As shown, the second pot body 300 includes an arc-shaped portion 310; in the height direction of the pot assembly, the contact portion 420 extends in an arc shape, and when the second pot body 300 is placed in the receiving cavity 110, the contact portion 420 fits against the arc-shaped portion 310.
[0123] In this embodiment, the contact portion 420 extends in an arc shape along the height direction of the pot assembly. 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.
[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 2 and Figure 6 As shown, the heating plate 200 is provided with a guide post 230, and the first pot body 100 is provided with a second through hole 150, with the guide post 230 passing through the second through hole 150.
[0126] In this embodiment, the guide post 230 passes through the second through hole 150 to guide the movement of the heating plate 200 and further improve the stability of the heating plate 200 during its 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.
[0128] like Figure 4As shown, the distance L2 between the first position and the second position is greater than 0 and less than or equal to 10 millimeters.
[0129] In this embodiment, the distance L2 between the first position and the second position is greater than 0 and less than or equal to 10 mm, so that the heat transfer element 400 can adapt to the arc-shaped part 310 with different curvatures, further improving the model or type of the second pot body 300 that the heat transfer element 400 can adapt to.
[0130] Specifically, the distance L2 between the first position and the second position is 2 millimeters.
[0131] The distance L2 between the first position and the second position is 5 millimeters.
[0132] The distance L2 between the first position and the second position is 7 millimeters.
[0133] The distance L2 between the first position and the second position is 10 mm.
