Description

Technical Field

[0001] This application relates to the field of household appliances, and particularly to a heating plate assembly and a liquid heating container. Background Art

[0002] A liquid heating container generally includes a container body and a heating plate assembly disposed at the bottom of the container body. The heating plate assembly includes a plate body, a heat conducting plate, and a heating tube. In the prior art, the plate body is connected to the bottom of the container body and serves as the container bottom. The heat conducting plate is connected to the bottom of the plate body, and the heating tube is connected to the side of the heat conducting plate facing away from the plate body. After the heating tube is energized, heat can be generated, and the heat is transferred to the plate body through the heat conducting plate, thereby heating the liquid in the container body.

[0003] During the working process of the liquid heating container, the temperature of the area on the heat conducting plate directly opposite to the heating tube is significantly higher than other areas, resulting in uneven heating of the bottom of the container body, and further resulting in uneven heating of the liquid in the container body, generating vibrations or large noises caused by the rupture of bubbles. Utility Model Content

[0004] This application provides a heating plate assembly and a liquid heating container, which can solve the problem of large noise caused by uneven heating of the bottom of the container body.

[0005] In a first aspect of this application, a heating plate assembly is provided, including a plate body provided with a first heat receiving portion and a second heat receiving portion; a heating tube installed on the bottom wall of the plate body, the heating tube including a top, a bottom, and a side; a heat conducting plate assembly including a first heat conducting portion, the first heat conducting portion being respectively connected to the top and the first heat receiving portion; the heat conducting plate assembly further including a second heat conducting portion and / or a third heat conducting portion, the second heat conducting portion being respectively connected to the bottom and the second heat receiving portion, and the third heat conducting portion being respectively connected to the side and the second heat receiving portion.

[0006] In the above solution, the heat conduction plate assembly can accelerate the heat conduction rate, reduce the heat loss during the heat transfer process, and also improve the heat conduction uniformity, ensuring that the heat of the heating tube is evenly conducted to the plate body. The first heat conduction part is used to evenly conduct the heat at the top to the first heat receiving part. Compared with the way that the top of the heating tube is directly connected to the first heat conduction part, it can improve the heat receiving uniformity of the first heat receiving part. When the heat conduction plate assembly is provided with a second heat conduction part or a third heat conduction part, the heat at the bottom or side of the heating tube can be directly conducted to the second heat receiving part, increasing the effective heat receiving area of the second heat receiving part. Compared with the way that the heat of the heating tube is indirectly conducted to the second heat receiving part through the first heat receiving part, it can reduce the temperature difference between the second heat receiving part and the first heat receiving part, improve the overall heat receiving uniformity of the plate body, make the liquid at the bottom of the container body evenly heated, and reduce the possibility of generating noise due to the local aggregation and rupture of bubbles caused by the relatively high local temperature of the plate body. Moreover, when the heat conduction plate assembly is provided with a second heat conduction part or a third heat conduction part, three-dimensional heat conduction of the heating tube can be realized, and more heat generated by the heating tube can be conducted to the plate body, which is beneficial to reducing the heat dissipation of the heating tube, improving the heat conduction efficiency of the heating plate assembly, and further improving the heating efficiency of the liquid heating container. When the heat conduction plate assembly is provided with the first heat conduction, second heat conduction part and third heat conduction part at the same time, the heat at the top, bottom and side of the heating tube can be conducted to the plate body as much as possible, thereby further improving the overall heat receiving uniformity of the plate body.

[0007] In a possible design, along the axial direction of the heating plate assembly, the first heat conduction part is clamped between the first heat receiving part and the top.

[0008] In the above solution, the two surfaces of the first heat conduction part that are oppositely arranged along the axial direction of the heating plate assembly are respectively attached to the first heat receiving part and the top, so that the first heat conduction part can quickly conduct the heat at the top to the first heat receiving part along the axial direction of the heating plate assembly. The heat conduction path is short, which can reduce the heat loss during the heat conduction process, thereby improving the heat conduction efficiency of the first heat conduction part.

[0009] In a possible design, the heat conduction plate assembly includes a first heat conduction plate and a second heat conduction plate; the second heat conduction plate includes the second heat conduction part, and the second heat conduction plate further includes a contact heat conduction part connected to the second heat conduction part. The contact heat conduction part is attached to the second heat receiving part along the axial direction of the heating plate assembly; the first heat conduction plate includes the first heat conduction part, and the first heat conduction plate is an annular structure with a through hole, and the through hole is used to accommodate the contact heat conduction part.

[0010] In the above solution, the heat conduction plate assembly is composed of a separate first heat conduction plate and a second heat conduction plate, which is convenient for installation. The first heat conduction plate is used to conduct the heat at the top of the heating tube to the first heat receiving part. By providing through holes, the first heat conduction plate can provide an avoidance space for the contact heat conduction part of the second heat conduction plate, so that the contact heat conduction part can fit with the second heat receiving part, enabling the second heat conduction plate to conduct the heat at the bottom of the heating tube to the second heat receiving part through the second heat conduction part and the contact heat conduction part, thereby realizing three-dimensional heat conduction of the heating tube. Moreover, since the contact heat conduction part fits with the second heat receiving part, it can increase the effective heat transfer area between the second heat conduction plate and the second heat receiving part, which is beneficial to improving the heat conduction efficiency and effect of the heating plate assembly.

[0011] In a possible design, a plurality of first limiting parts are arranged on the side wall of the first heat conduction plate, and the plurality of first limiting parts are spaced apart along the circumferential direction of the first heat conduction plate; the first limiting part is in limiting cooperation with the heating tube along the radial direction of the heating plate assembly.

[0012] In the above solution, the first limiting part is in limiting cooperation with the heating tube along the radial direction of the heating plate assembly, which can prevent relative movement between the first heat conduction plate and the heating tube along the radial direction of the heating plate assembly, and is beneficial to improving the structural stability of the heating plate assembly.

[0013] In a possible design, at least a part of the second heat receiving part is recessed in the direction close to the bottom along the axial direction of the heating plate assembly to form a first sub-heat receiving part and a second sub-heat receiving part. Along the axial direction of the heating plate assembly, both ends of the first sub-heat receiving part are respectively connected to the first heat receiving part and the second sub-heat receiving part; when the heat conduction plate assembly includes the second heat conduction part, the second heat conduction part is respectively connected to the bottom and the second sub-heat receiving part, and / or, when the heat conduction plate assembly includes the third heat conduction part, the third heat conduction part is respectively connected to the side part and the first sub-heat receiving part.

[0014] In the above solution, when the heat conduction plate assembly is provided with a second heat conduction part, the second heat conduction part is used to directly conduct the heat at the bottom of the heating tube to the second sub-heating part. Compared with the second heating part with a planar structure, the second heating part provided with the second sub-heating part shortens the heat transfer distance between the second heat conduction part and the second heating part, which is beneficial to reducing the heat loss during the heat conduction of the second heat conduction part and improving its heat conduction efficiency. When the heat conduction plate assembly is provided with a third heat conduction part, the third heat conduction part is used to directly conduct the heat at the side of the heating tube to the first sub-heating part. Compared with the second heating part with a planar structure, the second heating part provided with the first sub-heating part makes the second heating part closer to the side, facilitating the conduction of the heat at the side to the second heating part, which is beneficial to reducing the heat loss during the heat conduction of the third heat conduction part and improving its heat conduction efficiency. When the heat conduction plate assembly is provided with the first heat conduction part, the second heat conduction part and the third heat conduction part at the same time, the heat at the top, bottom and side of the heating tube can be conducted to the disk body as much as possible. And because the distance between the second heating part of the disk body and the bottom and side is shortened, the heat conduction rate of the heating disk assembly is faster and the heat loss is less, which is beneficial to further improving the heating efficiency of the liquid heating container.

[0015] In a possible design, when the heat conduction plate assembly includes the third heat conduction part, along the radial direction of the heating disk assembly, the third heat conduction part is clamped between the first sub-heating part and the side.

[0016] In the above solution, the two surfaces of the third heat conduction part that are oppositely arranged along the radial direction of the heating disk assembly are respectively attached to the first sub-heating part and the side, so that the third heat conduction part can quickly conduct the heat at the side to the first sub-heating part along the radial direction of the heating disk assembly. The heat conduction path is short, which can reduce the heat loss during the heat conduction process, thereby improving the heat conduction efficiency of the third heat conduction part.

[0017] In a possible design, the heat conduction plate assembly includes a first heat conduction plate, and the first heat conduction plate includes the connected first heat conduction part and the third heat conduction part; the first heat conduction plate further includes a contact heat conduction part, along the axial direction of the heating disk assembly, the contact heat conduction part is connected to one end of the third heat conduction part away from the first heat conduction part; the contact heat conduction part is attached to the second sub-heating part along the axial direction of the heating disk assembly.

[0018] In the above solution, the contact heat conduction part can conduct the heat of the third heat conduction part to the second sub-heating part, thereby reducing the temperature difference between the second sub-heating part and the first sub-heating part, improving the heat reception uniformity of the second heating part, and further improving the overall heat reception uniformity of the disk body, so that the liquid at the bottom of the container body is uniformly heated, reducing the possibility of noise generated by the local aggregation and rupture of bubbles due to the relatively high local temperature of the disk body.

[0019] In a possible design, the heat conducting plate assembly includes a first heat conducting plate and a second heat conducting plate; the second heat conducting plate includes the second heat conducting portion, and the second heat conducting plate further includes a contact heat conducting portion connected to the second heat conducting portion, and the contact heat conducting portion is attached to the second sub-heated portion along the axial direction of the heating plate assembly; the first heat conducting plate includes the connected first heat conducting portion and the third heat conducting portion, and the first heat conducting plate is an annular structure with a through hole, and the through hole is used to accommodate the contact heat conducting portion.

[0020] In the above solution, the heat conducting plate assembly is composed of a separate first heat conducting plate and a second heat conducting plate, which is convenient for installation. The first heat conducting plate is used to conduct the heat at the top to the first heated portion, and is also used to conduct the heat at the side to the first sub-heated portion. The heat at the bottom can be conducted to the second sub-heated portion through the second heat conducting portion and the contact heat conducting portion, so as to realize the three-dimensional heat conduction of the heating tube. Moreover, since the contact heat conducting portion is attached to the second sub-heated portion, the effective heat transfer area between the second heat conducting plate and the second sub-heated portion can be increased, which is beneficial to improving the heat conduction efficiency and heat conduction effect of the heating plate assembly.

[0021] In a possible design, a plurality of second limiting portions are provided on the side wall of the second heat conducting plate, and the plurality of second limiting portions are spaced apart along the circumferential direction of the second heat conducting plate; the second limiting portion and the third heat conducting portion jointly limit the radial movement of the heating tube along the heating plate assembly.

[0022] In the above solution, the second limiting portion and the third heat conducting portion can jointly limit the radial movement of the heating tube along the heating plate assembly. The second limiting portion and the heating tube can also be mutually limited in the radial direction of the heating plate assembly, preventing the relative movement of the second heat conducting plate and the heating tube along the radial direction of the heating plate assembly, which is beneficial to improving the structural stability of the heating plate assembly.

[0023] In the second aspect of the present application, a liquid heating container is provided, including a container body; a heating plate assembly, the heating plate assembly is the heating plate assembly described above, and the plate body is connected to the bottom of the container body and jointly encloses a containing cavity for containing liquid with the container body.

[0024] In the above solution, the heat conducting plate assembly is used to conduct the heat of the heating tube to the plate body, so as to heat the liquid in the containing cavity. The heating plate assembly can accelerate the heat conduction rate, reduce the heat loss in the heat transfer process, and can also improve the uniformity of heat conduction, ensuring that the heat of the heating tube is evenly conducted to the plate body, which is beneficial to improving the heating efficiency of the liquid heating container, making the liquid heating container have the advantages of high efficiency and silence.

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0065] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the angles shown in the drawings and should not be construed as limitations on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0066] The embodiments of the present application provide a liquid heating container, including a container body and a heating plate assembly disposed at the bottom of the container body. As Figure 1 shown, the heating plate assembly includes a plate body 1, a heating tube 2, and a heat conduction plate assembly 3. The plate body 1 is used for fixedly connecting with the bottom of the container body and jointly enclosing a containing cavity with the container body, and the containing cavity is used for containing liquid. Along the axial direction Z of the heating plate assembly, the heating tube 2 and the heat conduction plate assembly 3 are disposed on the side of the plate body 1 away from the containing cavity. The heat conduction plate assembly 3 is used for conducting the heat of the heating tube 2 to the plate body 1, so as to heat the liquid in the containing cavity. The heat conduction plate assembly 3 can accelerate the heat conduction rate, reduce the heat loss during the heat transfer process, and also improve the uniformity of heat conduction, ensuring that the heat of the heating tube 2 is evenly conducted to the plate body 1, which is beneficial to improving the heating efficiency of the liquid heating container.

[0067] Specifically, as Figure 2 shown, the plate body 1 is provided with a first heat receiving portion 11 and a second heat receiving portion 12. The heating tube 2 is installed on the bottom wall of the plate body 1, and the heating tube 2 includes a top portion 21, a bottom portion 22, and a side portion 23. The heat conduction plate assembly 3 includes a first heat conduction portion 301, and the first heat conduction portion 301 is respectively connected to the top portion 21 and the first heat receiving portion 11 to evenly conduct the heat of the top portion 21 to the first heat receiving portion 11. Compared with the way that the top portion 21 of the heating tube 2 is directly connected to the first heat conduction portion 301, the heat receiving uniformity of the first heat receiving portion 11 can be improved. The heat conduction plate assembly 3 further includes a second heat conduction portion 302 and / or a third heat conduction portion 303. The second heat conduction portion 302 is respectively connected to the bottom portion 22 and the second heat receiving portion 12 to conduct the heat of the bottom portion 22 to the second heat receiving portion 12; the third heat conduction portion 303 is respectively connected to the side portion 23 and the second heat receiving portion 12 to conduct the heat of the side portion 23 to the second heat receiving portion 12.

[0068] When the heat conducting plate assembly 3 is provided with the second heat conducting part 302 or the third heat conducting part 303, the heat at the bottom 22 or the side part 23 of the heating tube 2 can be directly conducted to the second heat receiving part 12, increasing the effective heat receiving area of the second heat receiving part 12. Compared with the way that the heat of the heating tube 2 is indirectly conducted to the second heat receiving part 12 through the first heat receiving part 11, the temperature difference between the second heat receiving part 12 and the first heat receiving part 11 can be reduced, improving the overall heat receiving uniformity of the disc body 1, enabling the liquid at the bottom of the container body to be heated evenly, and reducing the possibility of noise generated by the local aggregation and rupture of bubbles due to the relatively high local temperature of the disc body 1. Moreover, when the heat conducting plate assembly 3 is provided with the second heat conducting part 302 or the third heat conducting part 303, three-dimensional heat conduction of the heating tube 2 can be realized, conducting more heat generated by the heating tube 2 to the disc body 1, which is beneficial to reducing the heat dissipation of the heating tube 2 and improving the heat conduction efficiency of the heat conducting plate assembly 3, and further beneficial to improving the heating efficiency of the liquid heating container. When the heat conducting plate assembly 3 is simultaneously provided with the first heat conducting part 301, the second heat conducting part 302 and the third heat conducting part 303, the heat at the top 21, the bottom 22 and the side part 23 of the heating tube 2 can all be conducted to the disc body 1 as much as possible, thereby further improving the overall heat receiving uniformity of the disc body 1 and the heating efficiency of the liquid heating container, making the liquid heating container have the advantages of high efficiency and silence.

[0069] In this embodiment, the disc body 1 needs to be in contact with the liquid in the accommodating cavity. Therefore, the material of the disc body 1 can be food-grade stainless steel, such as SUS304 stainless steel or SUS316L stainless steel, or other models of stainless steel, and this embodiment does not limit this.

[0070] In a specific implementation manner, as Figure 2 shown, along the axial direction Z of the heating disc assembly, the first heat conducting part 301 is clamped between the first heat receiving part 11 and the top 21, that is, the two surfaces of the first heat conducting part 301 arranged oppositely along the axial direction Z of the heating disc assembly are respectively attached to the first heat receiving part 11 and the top 21, so that the first heat conducting part 301 can quickly conduct the heat of the top 21 along the axial direction Z of the heating disc assembly to the first heat receiving part 11. The heat conduction path is short, which can reduce the heat loss during the heat conduction process, thereby improving the heat conduction efficiency of the first heat conducting part 301.

[0071] As Figure 2 shown, the first heat receiving part 11 corresponds to the position of the first heat conducting part 301 along the axial direction Z of the heating disc assembly. Along the radial direction X of the heating disc assembly, the size of the first heat conducting part 301 should be greater than or equal to the size of the top 21 to ensure that the first heat conducting part 301 conducts more heat of the top 21 to the first heat receiving part 11.

[0072] Taking the heating tube 2 as an example of a circular heating tube 2, the remaining specific structures of the heating plate assembly will be described below. The first heat conduction part 301 is matched with the structure of the heating tube 2 and is also a circular structure; the first heat receiving part 11 is matched with the structure of the first heat conduction part 301 and is also a circular structure. Correspondingly, the second heat receiving part 12 is the part of the disc body 1 surrounded by the circular first heat receiving part 11.

[0073] As Figures 1 to 3 shown, in a specific embodiment, the part of the disc body 1 connected to the heat conduction plate assembly 3 is a planar structure. The heat conduction plate assembly 3 is a split structure for convenient installation, including a first heat conduction plate 31 and a second heat conduction plate 32. The first heat conduction plate 31 is a circular structure with a through hole 312. The first heat conduction plate 31 includes a first heat conduction part 301, that is, the first heat conduction plate 31 is used to conduct the heat of the top 21 to the first heat receiving part 11. The second heat conduction plate 32 includes a second heat conduction part 302. The second heat conduction plate 32 further includes a contact heat conduction part 304 connected to the second heat conduction part 302. The contact heat conduction part 304 is accommodated in the through hole 312 and is attached to the second heat receiving part 12 along the axial direction Z of the heating plate assembly, that is, the heat of the bottom 22 can be conducted to the second heat receiving part 12 through the second heat conduction part 302 and the contact heat conduction part 304, so as to realize the three-dimensional heat conduction of the heating tube 2. Moreover, since the contact heat conduction part 304 is attached to the second heat receiving part 12, the effective heat transfer area between the second heat conduction plate 32 and the second heat receiving part 12 can be increased, which is beneficial to improving the heat conduction efficiency and heat conduction effect of the heating plate assembly.

[0074] Specifically, as Figure 2 shown, the second heat conduction part 302 is a circular structure corresponding to the heating tube 2. Along the radial direction X of the heating plate assembly, the size of the second heat conduction part 302 should be greater than or equal to the size of the bottom 22 to ensure that the second heat conduction part 302 conducts more heat of the bottom 22 to the second heat receiving part 12. The second heat conduction part 302 and the contact heat conduction part 304 can be connected through a connecting part 305. When the connecting part 305 is perpendicular to the second heat conduction part 302 and the contact heat conduction part 304 respectively, the heat transfer distance between the second heat conduction part 302 and the contact heat conduction part 304 is the shortest and the heat conduction effect is the best.

[0075] As Figure 3As shown, the heating tube 2 includes a heating section 201 and connecting sections 202 located at both ends of the heating section 201. The heating section 201 is provided with a heating wire, and the connecting sections 202 are used to connect with other components of the liquid heating container and are not provided with heating wires. Therefore, a notch 322 corresponding to the position of the connecting section 202 can be provided on the second heat conducting plate 32. On the one hand, the notch 322 can expose the connecting section 202, facilitating connection with other components; on the other hand, setting the notch 322 can make the shape of the second heat conducting portion 302 match that of the heating section 201, avoiding waste of materials of the second heat conducting plate 32, and also being beneficial to reducing the weight of the second heat conducting plate 32 and the manufacturing cost of the heating disc assembly.

[0076] As Figure 2 and Figure 3 shown, a plurality of first limiting portions 311 are provided on the side wall of the first heat conducting plate 31. The plurality of first limiting portions 311 are spaced apart along the circumferential direction of the first heat conducting plate 31. The first limiting portions 311 can specifically extend in the direction of approaching the heating tube 2 along the axial direction Z of the heating disc assembly, so as to be in limiting cooperation with the heating tube 2 in the radial direction X of the heating disc assembly, thereby preventing relative movement between the first heat conducting plate 31 and the heating tube 2 along the radial direction X of the heating disc assembly, which is beneficial to improving the structural stability of the heating disc assembly.

[0077] In addition, in this embodiment, between the first heat conducting plate 31 and the disc body 1, between the first heat conducting plate 31 and the heating tube 2, between the second heat conducting plate 32 and the disc body 1, and between the second heat conducting plate 32 and the heating tube 2, they can all be fixedly connected by welding, which can not only improve the structural stability of the heating disc assembly but also be beneficial to improving the heat conduction efficiency of the heating disc assembly.

[0078] As Figures 4 to 7 shown, in another specific embodiment, the portion where the disc body 1 is connected to the heat conducting plate assembly 3 is not a planar structure. At least part of the second heat receiving portion 12 is recessed in the direction of approaching the bottom 22 along the axial direction of the heating disc assembly, so as to form a first sub-heat receiving portion 121 close to the side portion 23 and a second sub-heat receiving portion 122 close to the bottom 22. Along the axial direction Z of the heating disc assembly, both ends of the first sub-heat receiving portion 121 are respectively connected to the first heat receiving portion 11 and the second sub-heat receiving portion 122. When the heat conducting plate assembly 3 includes a second heat conducting portion 302, the second heat conducting portion 302 is respectively connected to the bottom 22 and the second sub-heat receiving portion 122, and / or when the heat conducting plate assembly 3 includes a third heat conducting portion 303, the third heat conducting portion 303 is respectively connected to the side portion 23 and the first sub-heat receiving portion 121.

[0079] As Figure 5As shown in the figure, when the heat conduction plate assembly 3 is provided with the second heat conduction part 302, the second heat conduction part 302 is used to directly conduct the heat of the bottom 22 of the heating tube 2 to the second sub-heated part 122. Moreover, compared with the second heated part 12 with a planar structure, the second heated part 12 provided with the second sub-heated part 122 shortens the heat transfer distance between the second heat conduction part 302 and the second heated part 12, which is beneficial to reducing the heat loss of the second heat conduction part 302 during the heat conduction process and improving its heat conduction efficiency. As Figure 7 shown in the figure, when the heat conduction plate assembly 3 is provided with the third heat conduction part 303, the third heat conduction part 303 is used to directly conduct the heat of the side part 23 of the heating tube 2 to the first sub-heated part 121. Moreover, compared with the second heated part 12 with a planar structure, the second heated part 12 provided with the first sub-heated part 121 makes the second heated part 12 closer to the side part 23, facilitating the conduction of the heat of the side part 23 to the second heated part 12, which is beneficial to reducing the heat loss of the third heat conduction part 303 during the heat conduction process and improving its heat conduction efficiency.

[0080] As Figure 5 shown in the figure, when the heat conduction plate assembly 3 is simultaneously provided with the first heat conduction part 301, the second heat conduction part 302 and the third heat conduction part 303, the heat of the top 21, bottom 22 and side part 23 of the heating tube 2 can be conducted to the disc body 1 as much as possible. And because the distance between the second heated part 12 of the disc body 1 and the bottom 22 and the side part 23 is shortened, the heat conduction rate of the heating disc assembly is faster and the heat loss is less, which is beneficial to further improving the heating efficiency of the liquid heating container.

[0081] Specifically, as Figure 5 and Figure 7 shown in the figure, when the heat conduction plate assembly 3 includes the third heat conduction part 303, along the radial direction X of the heating disc assembly, the third heat conduction part 303 is clamped between the first sub-heated part 121 and the side part 23, that is, the two surfaces of the third heat conduction part 303 arranged oppositely along the radial direction X of the heating disc assembly are respectively attached to the first sub-heated part 121 and the side part 23, so that the third heat conduction part 303 can quickly conduct the heat of the side part 23 to the first sub-heated part 121 along the radial direction X of the heating disc assembly. The heat conduction path is short, which can reduce the heat loss during the heat conduction process, thereby improving the heat conduction efficiency of the third heat conduction part 303.

[0082] For the case where the connection part between the disc body 1 and the heat conduction plate assembly 3 is not a planar structure, the present application provides two specific embodiments, as Figure 7 and Figure 8As shown, in the first specific embodiment, the heat conduction plate assembly 3 only includes an integral first heat conduction plate 31. The first heat conduction plate 31 includes a connected first heat conduction portion 301 and a third heat conduction portion 303, and also includes a contact heat conduction portion 304. Along the axial direction Z of the heating plate assembly, the contact heat conduction portion 304 is connected to one end of the third heat conduction portion 303 away from the first heat conduction portion 301, and the contact heat conduction portion 304 is attached to the second sub-heated portion 122 along the axial direction Z of the heating plate assembly.

[0083] In this example, since the second heat conduction portion 302 is not provided in the heat conduction plate assembly 3, the contact heat conduction portion 304 can conduct the heat of the third heat conduction portion 303 to the second sub-heated portion 122, thereby reducing the temperature difference between the second sub-heated portion 122 and the first sub-heated portion 121, improving the heat uniformity of the second heated portion 12, and further improving the overall heat uniformity of the disk body 1, so that the liquid at the bottom of the container body is uniformly heated, and reducing the possibility of noise generated by the local aggregation and rupture of bubbles due to the relatively high local temperature of the disk body 1.

[0084] As Figure 5 and Figure 9 As shown, the heat conduction plate assembly 3 is a split structure for convenient installation, including a first heat conduction plate 31 and a second heat conduction plate 32. The first heat conduction plate 31 is an annular structure with a through hole 312. The first heat conduction plate 31 includes a first heat conduction portion 301 and a third heat conduction portion 303, that is, the first heat conduction plate 31 is used to conduct the heat of the top 21 to the first heated portion 11, and is also used to conduct the heat of the side portion 23 to the first sub-heated portion 121. The second heat conduction plate 32 includes a second heat conduction portion 302. The second heat conduction plate 32 also includes a contact heat conduction portion 304 connected to the second heat conduction portion 302. The contact heat conduction portion 304 is accommodated in the through hole 312 and is attached to the second sub-heated portion 122 along the axial direction Z of the heating plate assembly, that is, the heat of the bottom 22 can be conducted to the second sub-heated portion 122 through the second heat conduction portion 302 and the contact heat conduction portion 304, so as to realize the three-dimensional heat conduction of the heating tube 2. And, since the contact heat conduction portion 304 is attached to the second sub-heated portion 122, it can increase the effective heat transfer area between the second heat conduction plate 32 and the second sub-heated portion 122, which is beneficial to improving the heat conduction efficiency and heat conduction effect of the heating plate assembly.

[0085] Specifically, as Figure 5As shown, the second heat conduction part 302 is an annular structure corresponding to the heating tube 2. Along the radial direction X of the heating plate assembly, the size of the second heat conduction part 302 should be greater than or equal to the size of the bottom 22 to ensure that the second heat conduction part 302 conducts more heat from the bottom 22 to the second sub-heated part 122. The second heat conduction part 302 and the contact heat conduction part 304 can be connected through a connecting part 305. When the connecting part 305 is perpendicular to the second heat conduction part 302 and the contact heat conduction part 304 respectively, the heat transfer distance between the second heat conduction part 302 and the contact heat conduction part 304 is the shortest and the heat conduction effect is the best.

[0086] The first heat conduction plate 31 may further include a clamping part 313. Along the axial direction Z of the heating plate assembly, the clamping part 313 is fixedly connected to one end of the third heat conduction part 303 away from the first heat conduction part 301. Along the axial direction Z of the heating plate assembly, the clamping part 313 is clamped between the second sub-heated part 122 and the second heat conduction part 302, which can limit the movement of the first heat conduction plate 31 along the axial direction Z of the heating plate assembly and is beneficial to improving the structural stability of the first heat conduction plate 31.

[0087] As Figure 9 shown, the heating tube 2 includes a heating section 201 and connecting sections 202 at both ends of the heating section 201. The heating section 201 is provided with a heating wire, and the connecting sections 202 are used for connecting with other components of the liquid heating container and are not provided with heating wires. Therefore, a notch 322 corresponding to the position of the connecting section 202 can be provided on the second heat conduction plate 32. On the one hand, the notch 322 can expose the connecting section 202 to facilitate connection with other components; on the other hand, setting the notch 322 can make the shape of the second heat conduction part 302 match the shape of the heating section 201, avoid wasting the material of the second heat conduction plate 32, and is also beneficial to reducing the weight of the second heat conduction plate 32 and the manufacturing cost of the heating plate assembly.

[0088] As Figure 9 shown, a plurality of second limiting parts 321 are provided on the side wall of the second heat conduction plate 32. The plurality of second limiting parts 321 are spaced along the circumferential direction of the second heat conduction plate 32. The second limiting parts 321 can specifically extend along the axial direction Z of the heating plate assembly towards the direction close to the heating tube 2 so as to jointly limit the movement of the heating tube 2 along the radial direction X of the heating plate assembly with the third heat conduction part 303. The second limiting parts 321 and the heating tube 2 can also be mutually limited in the radial direction X of the heating plate assembly to prevent relative movement between the second heat conduction plate 32 and the heating tube 2 along the radial direction X of the heating plate assembly, which is beneficial to improving the structural stability of the heating plate assembly.

[0089] In the above embodiments, the first heat conducting plate 31 and the second heat conducting plate 32 can be made of aluminum with good heat conducting performance and low price. The thickness of the first heat conducting plate 31 and the second heat conducting plate 32 should be 1.5 mm to 3 mm, so that the first heat conducting plate 31 and the second heat conducting plate 32 can not only have good heat conducting performance, but also maintain a certain structural strength to avoid the failure of the heat conducting plate assembly 3. Specifically, the thickness of the first heat conducting plate 31 and the second heat conducting plate 32 can be 1.5 mm, 1.7 mm, 1.9 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm or 3 mm, or other values within the above range, and this embodiment does not limit this.

[0090] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
