Description

Technical Field

[0001] This utility model relates to the field of cooking equipment, specifically to a liquid heating container. Background Technology

[0002] Existing liquid heating containers typically use heating elements, which are directly connected to the outside of the container bottom. This results in concentrated heating in the area of ​​the container bottom directly in contact with the heating element, while other areas receive less heat. When the heating element is operating, it causes uneven distribution of air bubbles at the container bottom, with denser bubbles in the area in contact with the heating element. The concentrated bursting of these bubbles at the bottom can cause resonance and generate significant noise. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a liquid heating container to at least solve the problem of excessive noise during the heating process.

[0004] One embodiment of this utility model provides a liquid heating container, which includes: a container body, the container body including a container bottom, the container bottom including an annular heating region; a heating plate including a heat-conducting plate and a heating element, the heat-conducting plate being disposed on the lower surface of the container bottom, and the heating element being disposed on the lower surface of the heat-conducting plate and located below the annular heating region; wherein, a plurality of first protrusions are formed on the upper surface of the annular heating region, a first groove is formed on the lower surface of each first protrusion, a plurality of second protrusions are formed in the area of ​​the heat-conducting plate corresponding to the plurality of first protrusions, each second protrusion being inserted into a corresponding first groove, and forming a gap channel for accommodating flux between the second protrusion and the first groove.

[0005] The liquid heating container provided in this embodiment has multiple first protrusions on the upper surface of the container bottom opposite the heating element. During the heating process, a large number of bubbles are generated in the area where the multiple first protrusions are located. However, the undulating structure of the multiple protrusions allows the bubbles to quickly detach from the container bottom, reducing the number of bubbles adhering to the container bottom and lowering the noise generated by bubble bursting. Furthermore, this embodiment welds the container bottom to the heat-conducting plate and pre-designs multiple second protrusions on the heat-conducting plate, allowing the second protrusions to extend into the first grooves formed on the back of the first protrusions. A gap is reserved between the first protrusions and the first grooves as a flow channel for accommodating flux. Compared to planar welding between the heat-conducting plate and the container bottom, the contact area between the flux and the heat-conducting plate and the container bottom is increased, which is beneficial for firmly welding the heat-conducting plate to the container bottom. Moreover, the first grooves can also guide the heat-conducting plate to align quickly, facilitating rapid installation. The container bottom and heat-conducting plate have simple structures and are easy to process and assemble.

[0006] In some embodiments, the first protrusion is a first rib extending circumferentially around the centerline of the container bottom, and a plurality of first ribs are spaced apart in the radial direction of the container bottom, wherein a plurality of first ribs are broken at at least one point in the circumferential direction.

[0007] In these embodiments, the first protrusion is a first rib, extending circumferentially around the center line of the container bottom, and roughly distributed in a ring shape. This facilitates the detachment of air bubbles from the container bottom from multiple directions, resulting in good noise reduction. Multiple first ribs are spaced apart in the radial direction of the container bottom, similar to a large ring enclosing a smaller ring, which is a reasonable layout and easy to manufacture. Furthermore, having at least one break in the circumferential direction of some of the first ribs—for example, all the first ribs being broken at least one place in the circumferential direction—reduces the obstruction effect of the first ribs on the container bottom on the liquid, thus reducing water residue on the container bottom after pouring.

[0008] In some embodiments, the second protrusion is a second rib extending circumferentially around the center line of the heating plate, and a plurality of second ribs are spaced apart in the radial direction of the bottom of the container, wherein a plurality of second ribs are broken at at least one point in the circumferential direction.

[0009] In these embodiments, the second protrusion is a second rib, also circumferentially distributed around the center line of the heating plate, facilitating insertion into the corresponding first groove. Furthermore, since both the first and second protrusions are ribs, the structure is simple and easy to manufacture. Moreover, by breaking at least one of the second ribs circumferentially, the flux flows more easily in the gap channel during welding, ensuring sufficient contact with the heat-conducting plate and increasing the welding strength between the heat-conducting plate and the container bottom.

[0010] In some embodiments, the heating element is a heating tube with a circumferential notch, and a relief opening is provided at the position of the heat conduction plate opposite to the notch. The area of ​​the bottom of the container opposite to the relief opening is the temperature measurement area. Among them, a number of first ribs are circumferentially broken by the temperature measurement area, and a number of second ribs are circumferentially broken at the relief opening.

[0011] In these embodiments, the bottom of the container has a temperature-measuring area. This temperature-measuring area is disconnected from the first circumferentially extending rib, has no uneven structure, and is relatively flat. This allows for a relatively flat temperature-measuring area to be fitted with the temperature-measuring device, facilitating accurate temperature measurement. Furthermore, this temperature-measuring area corresponds vertically to the notch on the circumferential surface of the heating element, and the corresponding position of the heat-conducting plate has a clearance opening. This allows the temperature-measuring device to fit directly into the temperature-measuring area of ​​the container bottom via the clearance opening, improving measurement accuracy. Moreover, since the temperature-measuring device is roughly located in the notch area of ​​the heating element, the heat generated by the heating element will not significantly affect the temperature-measuring device, further ensuring measurement accuracy.

[0012] In some embodiments, the heating element is a heating tube with a circumferential notch, and the portion of the heating element circumferentially opposite to the notch is a concentrated heating portion. The annular heating region includes a concentrated heating region vertically opposite to the concentrated heating portion. The concentrated heating region protrudes upward as a whole to form a third protrusion, and the lower surface of the third protrusion forms a second groove. A plurality of first ribs are circumferentially broken by the third protrusion, and the protrusion height of the first ribs is the same as the protrusion height of the third protrusion. The portions of a plurality of second ribs opposite to the second groove are inserted into the second groove.

[0013] In these embodiments, the concentrated heating portion of the heating element reaches a high temperature during heating, resulting in a high temperature in the corresponding concentrated heating areas above and below the container bottom. Therefore, by making the entire concentrated heating area of ​​the container bottom protrude upwards to form a third protrusion, and forming a second groove on the lower surface of the third protrusion, more flux can be filled between the second protrusion and the second groove when the heat-conducting plate is attached to the lower surface of the container bottom. Since the flux can affect the heat transfer from the heat-conducting plate to the container bottom, it can reduce the heat conduction efficiency between the concentrated heating portion of the heating element and the container bottom, which is beneficial to improving the uniformity of the overall heat conduction efficiency of the heating element. Moreover, making the entire concentrated heating area of ​​the container bottom protrude upwards to form a third protrusion, compared to multiple first protrusions, can reduce the contact area between the container bottom and the liquid. Through localized action, it can also neutralize the heat conduction efficiency between the container bottom and the liquid in the circumferential direction, which is beneficial to the uniform heating of the liquid in the container and improves the heating effect.

[0014] In some embodiments, a plurality of second ribs are broken at the same position in the circumferential direction, and / or all second ribs are broken at multiple points in the circumferential direction. This facilitates the flux flow within the gap channel to fully contact the heat-conducting plate, thereby improving the welding strength between the heat-conducting plate and the container bottom.

[0015] In some embodiments, the distance between the highest points of two radially adjacent first ribs ranges from 1 mm to 10 mm. This arrangement makes the first ribs reasonably laid out, which can both enable bubbles to quickly detach from the bottom of the container and facilitate the processing and forming of the container bottom and the heat-conducting plate.

[0016] Specifically, if the distance between the highest points of two radially adjacent first ribs is less than 1mm, the distance is too small, making it difficult to process the container bottom, and the positioning effect between the heat-conducting plate and the container bottom will also be poor. Conversely, if the distance between the highest points of two radially adjacent first ribs is greater than 10mm, the distance is too large, reducing the number of first ribs in the area corresponding to the heating element on the container bottom, which will affect the noise reduction effect. Therefore, designing the distance between the highest points of two radially adjacent first ribs to be between 1mm and 10mm can avoid the above problems.

[0017] In some embodiments, the protrusion height of the first rib ranges from 0.2mm to 2mm. This design ensures that the height of the first rib is reasonable, enabling bubbles to quickly escape from the container while also facilitating the processing and shaping of the container bottom and the heat-conducting plate.

[0018] Specifically, if the height of the first rib is less than 0.2mm, it is too low and the rib is too gentle, failing to effectively gather small air bubbles into larger ones and hindering the detachment of bubbles from the container bottom surface, thus failing to achieve noise reduction. Conversely, if the protrusion height of the first rib is greater than 2mm, the mold and forming of the container bottom cannot be completed, and liquid easily accumulates. Therefore, in this embodiment, the protrusion height of the first rib is between 0.2mm and 2mm, which facilitates processing, provides good noise reduction, and increases the contact area between the liquid and the container bottom within this height range, promoting uniform heating of the container bottom and reducing bubble formation, thereby achieving noise reduction. Furthermore, a sufficiently high first rib allows the first groove to have a certain depth, facilitating the insertion of the second rib into the first groove and guiding the heat transfer plate into place quickly.

[0019] In some embodiments, the top fillet radius of the first rib is 1 to 3 times that of the top fillet radius of the second rib. This allows for a suitable gap between the second rib and the first groove after the second rib extends into the first groove, ensuring a secure weld between the heat-conducting plate and the container bottom without significantly affecting the heat transfer speed.

[0020] Specifically, if the top fillet radius of the second rib is too small, and the ratio of the top fillet radius of the first rib to that of the second rib is too large, the gap between the top of the second rib and the first groove will become larger, requiring more flux and wasting material. Furthermore, the flux's heat conduction speed will affect the heat transfer speed from the heating element to the bottom of the container. If the top fillet radius of the second rib is too large, and the ratio of the top fillet radius of the first rib to that of the second rib is too small, the second rib will not easily insert into the first groove, resulting in poor positioning between the heat-conducting plate and the bottom of the container. Therefore, keeping the ratio of the top fillet radius of the first rib to that of the second rib between 1 and 3 can avoid these problems.

[0021] In some embodiments, the included angle between the two facing sides of two radially adjacent first ribs ranges from 90° to 150°, and / or the included angle between the two facing sides of two radially adjacent second ribs ranges from 90° to 150°.

[0022] If the included angle between the two facing sides of two radially adjacent first ribs is too small, the gap between the two adjacent first ribs will be too small, making it difficult to process and shape the first ribs. If the included angle between the two facing sides of two adjacent first ribs is too large, the gap between the two adjacent first ribs will be too large, and the area where the first ribs are located will be too flat, which is not conducive to the aggregation of small air bubbles into large air bubbles at the first ribs, and cannot achieve a good noise reduction effect. Moreover, an excessively large included angle results in a smaller number of first ribs, which is not conducive to increasing the contact area between the liquid and the bottom of the container, and is not conducive to uniform heating of the bottom of the container. Therefore, in these embodiments, the included angle between the two facing sides of two radially adjacent first ribs is between 90° and 150°, which can avoid the above problems at the same time, resulting in good noise reduction effect and promoting uniform heating of the bottom of the container. In addition, the included angle between the two facing sides of two radially adjacent second ribs is also between 90° and 150°, which facilitates the matching with the first groove, thereby facilitating the insertion of the second rib into the first groove.

[0023] In some embodiments, the heat-conducting plate is an aluminum plate or a copper plate. Aluminum or copper plates have good thermal conductivity, fast heat transfer, and are readily available and inexpensive materials.

[0024] In some embodiments, the thickness of the heat-conducting pad ranges from 1 mm to 10 mm.

[0025] In these embodiments, if the heat-conducting plate is too thin, the heating element will transfer heat very quickly in the longitudinal direction, increasing the formation of air bubbles at the bottom of the container and causing excessive noise when heating water. If the heat-conducting plate is too thick, it will increase the difficulty of molding the heat-conducting plate and increase the cost. Therefore, the thickness of the heat-conducting plate is made between 1mm and 10mm to facilitate the processing and molding of the heat-conducting plate and to avoid the problem of excessive noise when heating water due to an excessively thin heat-conducting plate.

[0026] In some embodiments, the thickness of the heat-conducting plate ranges from 1mm to 5mm. It offers good thermal conductivity, is easy to manufacture, saves materials, reduces costs, and is lightweight, making it convenient for users to handle liquid heating containers.

[0051] The following will combine Figures 1 to 12 This invention introduces a liquid heating container provided by an embodiment of the present invention. The liquid heating container can be an electric kettle, a health-preserving kettle, or a teapot, etc., and will not be listed here.

[0052] like Figures 1 to 4 , Figures 7 to 9 As shown, one embodiment of the present invention provides a liquid heating container, which includes: a container body 10, the container body 10 including a container bottom 110, the container bottom 110 including an annular heating region; a heating plate 20, including a heat-conducting plate 210 and a heating element 220, the heat-conducting plate 210 being disposed on the lower surface of the container bottom 110, and the heating element 220 being disposed on the lower surface of the heat-conducting plate 210 and located below the annular heating region; wherein, a plurality of first protrusions 111 are formed on the upper surface of the annular heating region corresponding to the heating element 220, a first groove 112 is formed on the lower surface of each first protrusion 111, a plurality of second protrusions 211 are formed on the heat-conducting plate 210 corresponding to the plurality of first protrusions, each second protrusion 211 being inserted into the corresponding first groove 112, and forming a gap channel 212 for accommodating flux between the second protrusion and the first groove 112.

[0053] The liquid heating container provided in this embodiment has multiple first protrusions 111 on the upper surface of the container bottom 110 opposite to the heating element 220. During the heating process of the heating element 220, a large number of bubbles are generated in the area where the multiple first protrusions 111 are located. However, the undulating structure of the multiple protrusions allows the bubbles to quickly detach from the container bottom 110, reducing the number of bubbles attached to the container bottom 110 and reducing the noise caused by bubble bursting. Moreover, the design of multiple first protrusions 111 can also increase the contact area between the container bottom 110 and the liquid inside the container body 10, which is beneficial to improving the heating efficiency of the container bottom 110.

[0054] Furthermore, in this embodiment, the container bottom 110 is welded to the heat-conducting plate 210, and the heat-conducting plate 210 is pre-designed to have multiple second protrusions 211, which extend into the first groove 112 formed on the back of the first protrusion 111. A gap is reserved between the first protrusion 111 and the first groove 112 as a flow channel 212 for accommodating the flux. The flow channel 212 serves to accommodate and guide the welding machine. Compared to planar welding between the heat-conducting plate 210 and the container bottom 110, the contact area between the flux and the heat-conducting plate 210 and the container bottom 110 is increased, which is beneficial for firmly welding the heat-conducting plate 210 to the container bottom 110. Moreover, the first groove 112 can also guide the heat-conducting plate 210 to quickly align, facilitating rapid alignment between the heat-conducting plate 210 and the container bottom 110. The container bottom 110 and the heat-conducting plate 210 have a simple structure and are easy to process and assemble.

[0055] Furthermore, since the area on the heat-conducting plate 210 corresponding to the first protrusion 111 is provided with a second protrusion 211, and the upper surface of the heat-conducting plate 210 is entirely flat, compared to the first groove 112 being filled with a thicker flux, the amount of flux can be reduced because flux affects the heat transfer rate, thereby reducing the influence of flux on the heat transfer rate and improving heating efficiency.

[0056] It should be noted that in this application, the first protrusion 111 protrudes upward based on the root of the first protrusion 111, without considering how the first protrusion 111 is shaped.

[0057] Specifically, the first protrusion 111 and the first groove 112 can be formed by pressing the container bottom 110. Using the middle of the upper surface of the container bottom 110 as a reference surface, the portion of the container bottom 110 opposite the heating element 220 can be pressed downwards to form multiple grooves on the upper surface of the container bottom 110. A first protrusion 111 is formed between adjacent grooves, with the top of the first protrusion 111 flush with the reference surface. Alternatively, the container bottom 110 can be pressed upwards and downwards simultaneously to form multiple first protrusions 111 and multiple first grooves 112, with the middle of the protrusion height of the first protrusion 111 flush with the reference surface. Furthermore, the container bottom 110 can be pressed upwards to form multiple first protrusions 111, with the roots of the multiple first protrusions 111 flush with the reference surface. Regardless of how the first protrusion 111 and the first groove 112 located on the lower surface of the first protrusion 111 are formed, as long as they have the corresponding concave and convex structures, they can enable the rapid detachment of bubbles and reduce noise, which is in line with the technical concept of this application.

[0058] Additionally, it should be noted that the width of the annular heating region in this application can be greater than the width of the cross-section of the heating element 220, and the two do not necessarily have to be the same. The annular heating region only needs to cover the heating element 220 in the vertical direction.

[0059] Furthermore, in some embodiments, such as Figure 4 , Figure 5 and Figure 10 As shown, the first protrusion 111 is a first rib extending circumferentially around the center line of the container bottom 110, and a plurality of first ribs are distributed at intervals in the radial direction of the container bottom 110, wherein some of the first ribs are broken at at least one point in the circumferential direction.

[0060] In these embodiments, the first protrusion 111 is a first rib, extending circumferentially around the center line of the container bottom 110, and is roughly distributed in a ring shape. This facilitates the detachment of air bubbles from the container bottom 110 from multiple directions, resulting in good noise reduction. Multiple first ribs are distributed at intervals in the radial direction of the container bottom 110, similar to a large ring enclosing a smaller ring, resulting in a reasonable layout, simple structure, and convenient processing. Furthermore, by having at least one of the first ribs broken in the circumferential direction—for example, all the first ribs broken in at least one place in the circumferential direction—the obstruction effect of the first ribs on the container bottom 110 on the liquid can be reduced, making it easier to reduce water residue on the container bottom 110 after pouring.

[0061] As an example, such as Figure 5 As shown, all or part of the first ribs are broken at the same point in the circumferential direction, which facilitates the water to flow out of the bottom 110 of the container when the container body 10 is poured, and also facilitates cleaning and processing.

[0062] As an example, such as Figure 10As shown, a portion of the first ribs near the center of the container bottom 110 are arranged in a ring, while another portion of the first ribs away from the center of the container bottom 110 are broken at a first point in the circumference. Some of these first ribs are also broken at a second point in the circumference. The circumferential break points of the multiple first ribs can be designed as needed.

[0063] Furthermore, in some embodiments, such as Figure 11 and Figure 12 As shown, the second protrusion 211 is a second rib extending circumferentially around the center line of the heating plate 20. A plurality of second ribs are distributed at intervals in the radial direction of the container bottom 110, and some of the second ribs are broken at at least one point in the circumferential direction.

[0064] In these embodiments, the second protrusion 211 is a second rib, also circumferentially distributed around the center line of the heating plate 20, facilitating insertion into the corresponding first groove 112. Furthermore, both the first protrusion 111 and the second protrusion 211 are ribs, resulting in a simple structure and easy processing. Moreover, by breaking at least one of the second ribs circumferentially, the flux flows more easily in the gap channel 212 during welding, fully contacting the heat-conducting plate 210, thereby increasing the welding strength between the heat-conducting plate 210 and the container bottom 110.

[0065] As an example, such as Figure 11 and Figure 12 As shown, all or part of the second ribs are broken at the same or similar position in the circumferential direction, which facilitates the flux to flow in the gap channel 212 and fully contact the heat conduction plate 210, and is also easy to process.

[0066] As an example, such as Figure 11 and Figure 12 As shown, all the second ribs are broken at multiple points in the circumference. This facilitates the flux flow within the gap channel 212 to fully contact the heat-conducting plate 210, thereby improving the welding strength between the heat-conducting plate 210 and the container bottom 110.

[0067] In a specific embodiment, such as Figure 5 and Figure 6 As shown, the heating element 220 is a heating tube with a circumferential notch 221. The heat conduction plate 210 is provided with a clearance opening 213 at a position that is vertically opposite to the notch 221. The area where the container bottom 110 is vertically opposite to the clearance opening 213 is the temperature measuring area 113. Among them, a number of first ribs are circumferentially broken by the temperature measuring area 113, and a number of second ribs are circumferentially broken at the clearance opening 213.

[0068] In this embodiment, the container bottom 110 has a temperature measuring area 113. This temperature measuring area is interrupted by the first circumferentially extending rib and has no concave-convex structure, being relatively flat, for example, extending horizontally. This allows the container bottom 110 to reserve a relatively flat temperature measuring area 113 to fit against the temperature measuring device, facilitating accurate temperature measurement. Furthermore, the temperature measuring area 113 corresponds vertically to the notch 221 on the circumferential direction of the heating element, and the heat-conducting plate 210 has a corresponding clearance opening 213. This allows the temperature measuring device to fit against the temperature measuring area 113 of the container bottom 110 via the clearance opening 213, directly measuring the temperature of the container bottom 110, thus improving measurement accuracy. Moreover, since the temperature measuring device is roughly located in the notch 221 area of ​​the heating element, the heat generated by the heating element will not significantly affect the temperature measuring device, further ensuring measurement accuracy.

[0069] It is worth noting that the number of first ribs that are circumferentially broken by the temperature measuring area 113 is related to the area occupied by the temperature measuring area 113. If the area occupied by the temperature measuring area 113 is larger, and there are more first ribs extending circumferentially to the edge of the temperature measuring area 113, then there will be more first ribs that are broken at that point. The first ribs located radially inside the temperature measuring area 113 can be broken at the temperature measuring area 113, or they can maintain a continuous ring-shaped distribution without breaking.

[0070] Similarly, the design of the clearance opening 213 will also block the circumferential distribution of the second rib. Of course, the second rib located inside the clearance opening 213 can be circumferentially broken at the clearance opening 213, or it can maintain a continuous ring distribution without breaking.

[0071] Figure 5 A top view of the container bottom 110 is shown. Figure 5 The dashed line shows the outline of the heat-conducting plate 210 and the heating element 220 below the container bottom 110. Figure 5 As can be seen, the clearance 213 and the notch 221 of the heating element are vertically opposite each other, and the temperature measuring area 113 and the clearance 213 are downwardly opposite each other, thus facilitating the temperature measuring device to contact the temperature measuring area 113 at the notch 221 of the heating element for temperature measurement. The area occupied by the multiple first protrusions 111 forms an annular region. The temperature measuring area 113 is located within this annular region and close to its outer edge. Some of the first protrusions 111 within the annular region are circumferentially separated by the temperature measuring area 113. This temperature measuring area 113 is far from the heating body of the heating element, which is beneficial for accurate temperature measurement. Of course, in other examples, all the first protrusions 111 can also be circumferentially separated by the temperature measuring area 113 to prevent water from remaining in the bottom 110 of the container when pouring water.

[0072] Furthermore, such as Figure 6 and Figure 10As shown, the heating element 220 is a heating tube with a circumferential notch 221. The part of the heating element 220 that is circumferentially opposite to the notch 221 is the concentrated heating part 222. The annular heating area includes the area that is vertically opposite to the concentrated heating part 222 as the concentrated heating area. The concentrated heating area protrudes upward as a whole to form a third protrusion 114. The lower surface of the third protrusion 114 has a second groove. Among them, a number of first ribs are circumferentially broken by the third protrusion 114, and the protrusion height of the first ribs is the same as the protrusion height of the third protrusion 114. The parts of multiple second ribs that are opposite to the second groove are inserted into the second groove.

[0073] The concentrated heating portion 222 of the heating element 220 reaches a high temperature during heating, resulting in a high temperature in the corresponding concentrated heating areas above and below the container bottom 110 and the concentrated heating portion 222. Therefore, the concentrated heating area of ​​the container bottom 110 is made to bulge upward to form a third protrusion 114, and a second groove is formed on the lower surface of the third protrusion 114. The second groove has a large volume, so when the heat conduction plate 210 is attached to the lower surface of the container bottom 110, more flux can be filled between the second protrusion and the second groove. Since the flux can affect the heat transfer from the heat conduction plate 210 to the container bottom 110, it can reduce the heat conduction efficiency between the concentrated heating portion 222 of the heating tube and the container bottom 110, which is beneficial to improving the uniformity of the overall conduction efficiency of the heating tube. Furthermore, by making the concentrated heating area of ​​the container bottom 110 protrude upward to form a third protrusion 114, compared with multiple first protrusions 111, the contact area between the container bottom 110 and the liquid can be reduced. Through local action, the heat conduction efficiency between the container bottom 110 and the liquid in the circumferential direction can also be neutralized, which is conducive to the uniform heating of the liquid in the container body 10 and improves the heating effect.

[0074] It should be noted that the width of the annular heating area can be equal to or greater than the radial width of the concentrated heating area at the bottom 110 of the container. If the width of the annular heating area is equal to the radial width of the concentrated heating area at the bottom 110 of the container, then all the first ribs can be circumferentially interrupted by the third protrusion 114. If the width of the annular heating area is greater than the radial width of the concentrated heating area at the bottom 110 of the container, then... Figure 10 As shown, a portion of the first rib can be circumferentially broken by the third protrusion 114.

[0075] Furthermore, in some embodiments, such as Figure 7 and Figure 8 As shown, the distance X between the highest points of two radially adjacent first ribs ranges from 1mm to 10mm. This arrangement makes the first ribs reasonably laid out, which not only enables bubbles to quickly detach from the container bottom 110, but also facilitates the processing and forming of the container bottom 110 and the heat-conducting plate 210.

[0076] Specifically, if the distance X between the highest points of two radially adjacent first ribs is less than 1 mm, the interval is too small, making it difficult to process the container bottom 110, and the positioning effect between the heat-conducting plate 210 and the container bottom 110 will also be poor. Conversely, if the distance X between the highest points of two radially adjacent first ribs is greater than 10 mm, the interval is too large, reducing the number of first ribs in the area corresponding to the heating element 220 on the container bottom 110, which will affect the noise reduction effect. Therefore, designing the distance X between the highest points of two radially adjacent first ribs to be between 1 mm and 10 mm can avoid the above problems.

[0077] As an example, the distance X between the highest points of two radially adjacent first ribs is 3mm, 5mm or 8mm.

[0078] Furthermore, in some embodiments, such as Figure 7 and Figure 8 As shown, the protrusion height Y of the first rib ranges from 0.2mm to 2mm. This setting makes the height of the first rib reasonable, which can both enable bubbles to quickly escape from the container and facilitate the processing and forming of the container bottom 110 and the heat-conducting plate 210.

[0079] Specifically, if the protrusion height Y of the first rib is less than 0.2mm, the height is too low, the rib is too gentle, and it cannot effectively gather small air bubbles at the first rib into large air bubbles, nor is it conducive to the bubbles detaching from the surface of the container bottom 110, thus failing to achieve the noise reduction effect. Conversely, if the protrusion height Y of the first rib is greater than 2mm, the mold and forming of the container bottom 110 cannot be completed, and liquid is prone to accumulate. Therefore, in this embodiment, the protrusion height Y of the first rib is between 0.2mm and 2mm, which is convenient to process, has a good noise reduction effect, and the rib within this height range can also increase the contact area between the liquid and the container bottom 110, which is conducive to the uniform heating of the container bottom 110, thereby reducing the occurrence of air bubbles and achieving the noise reduction effect. Moreover, the first rib is high enough, and the first groove 112 can also have a certain depth, which is conducive to guiding the second rib to be inserted into the first groove 112, thereby guiding the heat transfer plate 210 to be quickly installed in place.

[0080] As an example, the protrusion height Y of the first rib is 0.5mm, 1mm, or 1.4mm.

[0081] Furthermore, in some embodiments, such as Figure 7 and Figure 8As shown, the top fillet radius Ra of the first rib is 1 to 3 times the top fillet radius Rb of the second rib. In this way, after the second rib extends into the first groove 112, there can be a gap channel 212 of appropriate size between the second rib and the first groove 112, which ensures that the heat conduction plate 210 and the container bottom 110 are firmly welded together, without significantly affecting the heat conduction speed.

[0082] Specifically, if the top fillet radius Rb of the second rib is too small, the ratio of the top fillet radius Ra of the first rib to the top fillet radius Rb of the second rib will be too large. This will result in a larger gap flow channel 212 between the top of the second rib and the first groove 112, requiring more flux and wasting material. Moreover, due to the influence of the flux's heat conduction speed, it will affect the heat transfer speed from the heating element 220 to the container bottom 110. If the top fillet radius Rb of the second rib is too large, the ratio of the top fillet radius Ra of the first rib to the top fillet radius Rb of the second rib will be too small. In this case, the second rib will not be easily inserted into the first groove 112, leading to a poorer positioning effect between the heat-conducting plate 210 and the container bottom 110. Therefore, keeping the ratio of the top fillet radius Ra of the first rib to the top fillet radius Rb of the second rib between 1 and 3 can avoid the above problems. As an example, the top fillet radius Ra of the first rib is 1.5 times or 2 times the top fillet radius Rb of the second rib.

[0083] Furthermore, in some embodiments, such as Figure 7 and Figure 8 As shown, the included angle ∠a between the two facing sides of two radially adjacent first ribs ranges from 90° to 150°, and / or the included angle between the two facing sides of two radially adjacent second ribs ranges from 90° to 150°, that is, the included angle ∠b ranges from 90° to 150°.

[0084] If the included angle ∠a between the two facing sides of two radially adjacent first ribs is too small, the gap between the two adjacent first ribs will be too small, making it difficult to process and shape the first ribs. If the included angle ∠a between the two facing sides of two adjacent first ribs is too large, the gap between the two adjacent first ribs will be too large, and the area where the first ribs are located will be too flat, which is not conducive to the aggregation of small air bubbles into large air bubbles at the first ribs, and cannot achieve a good noise reduction effect. Moreover, an excessively large included angle ∠a results in a smaller number of first ribs, which is not conducive to increasing the contact area between the liquid and the container bottom 110, and is not conducive to the uniform heating of the container bottom 110. Therefore, in these embodiments, the included angle ∠a between the two facing sides of two radially adjacent first ribs is between 90° and 150°, which can avoid the above problems at the same time, resulting in good noise reduction effect and promoting uniform heating of the container bottom 110. In addition, the included angle between the two facing sides of two radially adjacent second ribs is also between 90° and 150°, which facilitates the matching with the first groove 112, thereby making it easier for the second rib to be inserted into the first groove 112.

[0085] Furthermore, the included angle ∠a is greater than the included angle ∠b, which facilitates the insertion of the second rib into the first groove 112. The difference between the included angles ∠a and ∠b is between 5° and 15°.

[0086] As an example, the included angle ∠a is 100° or 130°, and the included angle ∠b is 90° or 120°.

[0087] Furthermore, in some embodiments, the heat-conducting plate 210 is an aluminum plate or a copper plate. Aluminum or copper plates have good thermal conductivity, fast heat transfer, and are readily available and inexpensive materials.

[0088] Furthermore, in some embodiments, such as Figure 7 and Figure 8 As shown, the thickness H of the heat-conducting plate 210 ranges from 1 mm to 10 mm.

[0089] In these embodiments, if the heat-conducting plate 210 is too thin, the heating element 220 will transfer heat longitudinally very quickly, increasing the generation of air bubbles at the bottom 110 of the container and causing excessive noise when the liquid is heated. If the heat-conducting plate 210 is too thick, it will increase the difficulty of molding the heat-conducting plate 210 and increase the cost. Therefore, the thickness H of the heat-conducting plate 210 is made between 1mm and 10mm to facilitate the processing and molding of the heat-conducting plate 210 and to avoid the problem of excessive noise when heating water due to the heat-conducting plate 210 being too thin.

[0090] Furthermore, the thickness of the heat-conducting plate 210 ranges from 1mm to 5mm. It offers good thermal conductivity, is easy to manufacture, saves materials, reduces costs, and its lightweight design makes it convenient for users to handle liquid heating containers. For example, the thickness of the heat-conducting plate 210 can be 2mm or 4mm.

[0091] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
