Description

Technical Field

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

[0002] Liquid heating containers typically include a container body, a bottom cover, a heating plate, and a heat insulation cover. The bottom of the container body has an opening, and the heating plate is connected to the container body via sealant to seal the opening. The bottom cover is directly connected to the bottom of the container body to support it. The heat insulation cover is located on the inner bottom of the bottom cover and covers the heating plate from below. The components at the bottom of the container body are assembled separately, resulting in low assembly efficiency. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a liquid heating container that can improve the assembly efficiency of the liquid heating container.

[0004] One embodiment of the present invention provides a liquid heating container, comprising: a container body having a container bottom wall; a fixing frame fixed to the container bottom wall, the fixing frame having a through hole extending vertically; a heating plate connected to the fixing frame, at least a portion of the heating plate extending into the through hole to heat the liquid inside the container body; and a container bottom cover connected to the fixing frame, the container bottom cover surrounding the fixing frame and the heating plate, and circumferentially supporting the bottom of the container body.

[0005] The liquid heating container provided in this embodiment connects both the heating plate and the container bottom cover to a fixed frame, so that the fixed frame is connected to the bottom wall of the container. Compared with the heating plate and the container bottom cover being connected to the container body separately, which requires the container body to be connected to the heating plate and the container bottom cover at different positions, this method is beneficial to improving the assembly efficiency of the liquid heating container. Moreover, it can simplify the processing precision of the container body and improve the product processing qualification rate.

[0006] Furthermore, having a bottom wall in the container body, compared to an open bottom, prevents leakage. Also, placing the heating plate into the through-hole of the mounting bracket to heat the container, with the heating plate close to the bottom wall, ensures efficient heating. Additionally, the partial horizontal overlap between the heating plate and the mounting bracket helps reduce the height of the container's bottom, thus reducing the overall height of the liquid heating container.

[0007] Furthermore, in some embodiments, the fixing frame is provided with an upward-facing glue applicator, which is filled with sealant, and the fixing frame is fixedly connected to the bottom wall of the container by the sealant.

[0008] In these embodiments, the mounting bracket is securely connected to the bottom wall of the container using sealant. Furthermore, compared to the prior art where the sealant is filled onto the heating plate, the heating plate extends into the through-hole of the mounting bracket, creating an assembly gap between them. This reduces the impact of the heating plate's temperature on the mounting bracket, effectively lowering the chance of sealant detachment and ensuring the installation stability of the mounting bracket, thereby ensuring the installation stability of the heating plate and the container bottom cover.

[0009] Furthermore, in some embodiments, the liquid heating container further includes a protective cover connected to the mounting bracket. The protective cover covers at least the bottom of the heating plate and can reduce the heat radiation transmitted from the heating plate to the outside of the protective cover. The heating plate is disposed on the protective cover.

[0010] In these embodiments, a protective cover is used to at least cover the bottom of the heating plate to prevent heat transfer from the heating plate to the outside of the protective cover, thus avoiding high-temperature damage to the outer components of the protective cover. Furthermore, connecting the protective cover to the mounting bracket, rather than fixing it to the container bottom cover, simplifies the structure of the container bottom cover and facilitates assembly. In addition, placing the heating plate on the protective cover, in other words, using the protective cover to support the heating plate, improves the installation stability of the heating plate.

[0011] Furthermore, in some embodiments, a portion of the protective cover extends into the through-hole to cover the outer periphery of the heating plate.

[0012] In these embodiments, the protective cover can also block the heat radiation from the heating plate to the mounting bracket, preventing the bracket from melting and improving the connection stability between the bracket and the container body. This, in turn, improves the installation stability of the connected protective cover and heating plate. Moreover, the partial overlap between the protective cover and the mounting bracket in the horizontal direction helps to reduce the overall height of the container body's bottom.

[0013] Furthermore, in some embodiments, the protective cover is a reflector or a heat shield.

[0014] In these embodiments, the protective cover can be a reflector, which reduces the outward transfer of heat radiation by reflecting the heat radiation generated by the heating element. This prevents melting of the outer components of the protective cover and also helps to reflect the heat radiation back to the container, improving the heating efficiency of the heating plate. The protective cover can also be a heat insulation cover, which can block heat and reduce the outward transfer of heat radiation from the heating plate, thereby preventing damage to the protective cover components due to high temperatures.

[0015] Furthermore, in some embodiments, the mounting bracket is made of plastic. This is lightweight and low-cost. Moreover, because the mounting bracket has a through-hole into which the heating plate extends, and because there is an assembly gap between the heating plate and the mounting bracket, the heating plate does not directly transfer heat to the mounting bracket, thus preventing the mounting bracket from melting. Especially when part of the protective cover also extends into the through-hole, the protective cover, in conjunction with heat insulation, can further prevent the mounting bracket from deforming due to high temperatures.

[0016] Furthermore, in some embodiments, the container bottom cover is secured to the mounting bracket by a first screw. The connection between the two is secure.

[0017] Furthermore, in some embodiments, a vertically extending threaded post is provided at the bottom of the mounting bracket, and the first screw passes through the container bottom cover and is inserted into the threaded post. Providing a threaded post on the mounting bracket here can prevent damage to the mounting bracket during the tightening of the first screw, and the threaded post can increase the tightening depth of the first screw, thereby improving the connection stability between the mounting bracket and the container bottom cover.

[0018] Furthermore, in some embodiments, the bottom wall of the protective cover is provided with an opening, and the liquid heating container also includes a thermostat, which is fixedly connected to the bottom of the heating plate through the opening.

[0019] In these embodiments, an opening is provided in the protective cover to facilitate the thermostat's monitoring of the heating plate temperature. Furthermore, fixing the thermostat to the bottom of the heating plate eliminates the need for a support structure on the container bottom cover, simplifying the container bottom cover structure and making manufacturing easier.

[0020] Furthermore, in some embodiments, the thermostat is secured to the heating plate by a second screw. The connection between the two is secure.

[0021] Furthermore, in some embodiments, the heating plate includes a plate body and heating tubes located at the bottom of the plate body. The heating tubes are circumferentially distributed around a center line perpendicular to the center line of the plate body. The bottom wall of the cover has upwardly protruding ribs on the four sides of the opening, and the ribs surround the outer periphery of the thermostat.

[0022] In these embodiments, the raised ribs can block the heat radiation from the heating element to the thermostat, which helps the thermostat to accurately detect the plate temperature without being affected by the heating element.

[0023] Furthermore, in some embodiments, the liquid heating container further includes: an upper coupler connected to a temperature controller, the container bottom cover having a clearance hole through which the upper coupler is exposed; a power base having a flat upper surface, a lower coupler in the middle of the upper surface of the power base, the container bottom cover being detachably placed on the upper surface of the power base, and the upper coupler being coupled to the lower coupler.

[0024] In these embodiments, the container bottom cover and the power base are detachable, allowing for easy removal of the container body and base to collect or pour liquids. Furthermore, the upper surface of the power base is flat, which reduces the overall height of the power base compared to a recessed top to accommodate the container body.

[0025] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and in part will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0036] The following will combine Figures 1 to 10 This invention introduces a liquid heating container provided by an embodiment of the present invention.

[0037] like Figures 1 to 5 As shown, one embodiment of the present invention provides a liquid heating container, comprising: a container body 100 having a container bottom wall 110; a fixing frame 200 fixed to the container bottom wall 110, the fixing frame 200 having a through hole 210 extending vertically; a heating plate 300 connected to the fixing frame 200, at least a portion of the heating plate 300 extending into the through hole 210 to heat the liquid in the container body 100; and a container bottom cover 700 connected to the fixing frame 200, the container bottom cover 700 surrounding the fixing frame 200 and the heating plate 300, and circumferentially supported on the bottom of the container body 100.

[0038] The liquid heating container provided in this embodiment connects both the heating plate 300 and the container bottom cover 700 to the fixing frame 200, so that the fixing frame 200 is connected to the container bottom wall 110. Compared with the heating plate 300 and the container bottom cover 700 being connected to the container body 100 respectively, which requires the container body 100 to be connected to the heating plate 300 and the container bottom cover 700 at different positions, this method is beneficial to improving the assembly efficiency of the liquid heating container. Moreover, it can simplify the processing precision of the container body 100 and improve the product processing qualification rate.

[0039] Furthermore, having a bottom wall 110 in the container body 100, compared to an open bottom, prevents water leakage from the bottom of the container body 100. Also, by inserting the heating plate 300 into the through hole 210 of the fixing frame 200 to heat the container body 100, the proximity of the heating plate 300 to the bottom wall 110 ensures efficient heating. Moreover, the partial horizontal overlap between the heating plate 300 and the fixing frame 200 helps reduce the height of the bottom of the container body 100, thereby reducing the overall height of the liquid heating container.

[0040] In addition, compared with the existing technology of applying glue to the heating plate 300 to directly connect it to the container body 100, using the fixing bracket 200 to connect to the container body 100 can prevent the sealant from falling off due to long-term contact with the high temperature of the heating plate 300, and can improve the installation stability of the heating plate 300.

[0041] Regarding the connection method between the fixing frame 200 and the container body 100, further, in some embodiments, such as Figure 6 , Figure 9 and Figure 10 As shown, the fixing frame 200 is provided with a glue applicator 220 with the groove opening facing upward. The glue applicator 220 is filled with sealant, and the fixing frame 200 is fixedly connected to the bottom wall 110 of the container through the sealant.

[0042] In these embodiments, the mounting bracket 200 is securely connected to the container bottom wall 110 via sealant. Furthermore, compared to the prior art where sealant is filled onto the heating plate 300, the heating plate 300 extends into the through hole 210 of the mounting bracket 200. This creates an assembly gap between the mounting bracket 200 and the heating plate 300, reducing the impact of the heating plate 300's temperature on the mounting bracket 200. This effectively lowers the likelihood of sealant detachment, ensuring the installation stability of the mounting bracket 200, and consequently ensuring the installation stability of the heating plate 300 and the container bottom cover 700.

[0043] Of course, the connection between the fixing frame 200 and the bottom wall 110 of the container is not limited to this; they can also be connected by welding, etc.

[0044] Furthermore, in some embodiments, such as Figures 2 to 5 , Figure 10As shown, the liquid heating container also includes a protective cover 400, which is connected to the fixing frame 200. The protective cover 400 covers at least the bottom of the heating plate 300, which can reduce the heat radiation transmitted from the heating plate 300 to the outside of the protective cover 400. The heating plate 300 is disposed on the protective cover 400 and connected to the fixing frame 200 through the protective cover 400.

[0045] In these embodiments, a protective cover 400 is used to cover at least the bottom of the heating plate 300 to prevent heat transfer from the heating plate 300 to the outside of the protective cover 400, thus avoiding high-temperature damage to the outer components of the protective cover 400. Furthermore, connecting the protective cover 400 to the mounting bracket 200, rather than fixing it to the container bottom cover 700, simplifies the structure of the container bottom cover 700 and facilitates assembly. In addition, by placing the heating plate 300 on the protective cover 400—in other words, using the protective cover 400 to support the heating plate 300—compared to the related art where adhesive is directly applied to the heating plate 300 to connect it to the container bottom wall 110, the connection of the heating plate 300 to the container bottom wall 110 via the protective cover 400 and the mounting bracket 200 prevents sealant from falling off, thus improving the installation stability of the heating plate 300.

[0046] Furthermore, such as Figure 10 As shown, a portion of the protective cover 400 can extend into the through hole 210 to cover the outer periphery of the heating plate 300. Another portion of the protective cover 400 extends below the mounting bracket 200 to connect with the mounting bracket 200.

[0047] The protective cover 400 can block the heat radiation from the heating plate 300 to the mounting bracket 200, preventing the mounting bracket 200 from melting and improving the connection stability between the mounting bracket 200 and the container body 100. This, in turn, improves the installation stability of the protective cover 400 and the heating plate 300 connected to it. Furthermore, by extending part of the protective cover 400 under the mounting bracket 200 for connection, it does not occupy the internal space of the through hole 210, making connection convenient.

[0048] As an example, such as Figure 7 and Figure 10 As shown, the protective cover 400 includes a bottom wall 420 and side walls 410 distributed circumferentially along the outer edge of the bottom wall 420. The side walls 410 at least partially extend into the through hole 210. The bottom wall 420 is located below the heating plate 300, directly or indirectly supporting the heating plate 300. The top of the side wall 410 of the protective cover 400 can contact the bottom wall 110 of the container body 100, thus preventing heat from leaking out through the gap between the protective cover 400 and the container body 100. Alternatively, a gap can be left between the top of the side wall 410 of the protective cover 400 and the bottom wall 110 of the container body 100.

[0049] As an example, such as Figure 6 , Figure 7 and Figure 10 As shown, a positioning post 250 is provided at the bottom of the fixing frame 200, causing a portion of the side wall 410 of the cover to bend outward to form a connecting ear 411. The connecting ear 411 extends to the bottom of the positioning post 250, and a screw passes through the connecting ear 411 and is inserted into the positioning post 250. The fixing frame 200 and the protective cover 400 are connected by screws, ensuring a secure connection. Moreover, the design of the fixing post prevents damage to the fixing frame 200 during screw tightening. The design of the connecting ear 411 simplifies the structure of the protective cover 400 and facilitates manufacturing.

[0050] Alternatively, the bottom wall 420 of the cover can have outwardly protruding connecting ribs (not shown in the figure) extending below the fixing frame 200, with screws passing through the connecting ribs and connecting to the fixing frame 200. Connecting to the fixing frame 200 via connecting ribs avoids affecting the insertion of the side wall 410 into the through hole 210 of the fixing frame 200, while also facilitating connection to the fixing frame 200. The connecting ribs can be ring-shaped, or there can be multiple connecting ribs distributed circumferentially around the center line of the protective cover 400.

[0051] In addition, there can be multiple screws at this location, circumferentially spaced around the center line of the protective cover 400.

[0052] Of course, the protective cover 400 can also be threaded or snapped to the fixing bracket 200. For example, the outer surface of the side wall 410 of the protective cover 400 has external threads, and the inner wall of the through hole 210 of the fixing bracket 200 has internal threads that are compatible with the external threads, etc., and is not limited to the above examples.

[0053] Furthermore, in some embodiments, the heating plate 300 is attached to the outer surface of the container bottom wall 110, which facilitates the rapid transfer of heat from the heating plate 300 to the container body 100.

[0054] Regarding the connection method between the heating plate 300 and the protective cover 400, further, in some embodiments, such as Figure 2 , Figure 3 and Figure 10 As shown, the liquid heating container may also include an elastic element 430, which is sandwiched between the protective cover 400 and the heating plate 300 to press the heating plate 300 against the outer surface of the container bottom wall 110 of the container body 100.

[0055] Here, the elastic element 430 is used to press the heating plate 300 against the bottom wall 110 of the container body 100. On the one hand, this ensures that the heating plate 300 is fully attached to the container body 100, thereby ensuring the heating effect of the heating plate 300. On the other hand, it eliminates the need to apply glue to the heating plate 300 to connect it to the container body 100, thereby preventing the heating plate 300 from falling off due to glue failure and improving the installation stability of the heating plate 300.

[0056] As an example, the elastic element 430 can be a spring, such as a disc spring, which has good elasticity and high temperature resistance. Of course, the elastic element 430 can also be other structures.

[0057] As an example, there are multiple elastic elements 430, which are distributed circumferentially around the center line perpendicular to the heating plate 300. This multi-point support of the heating plate 300 by multiple elastic elements 430 facilitates full contact between the heating plate 300 and the bottom wall 110 of the container body 100, thereby ensuring effective heating. For example, the number of elastic elements 430 can be 3, 4, or 6, etc.

[0058] As an example, the elastic element 430 is supported between the bottom wall 420 of the protective cover 400 and the heating plate 300. The elastic element 430 supports the heating plate 300 vertically, providing good support. Furthermore, to prevent displacement of the elastic element 430, the end of the elastic element 430 away from the heating plate 300 can be fixedly connected to the bottom wall 420. Alternatively, a limiting element can be provided on the bottom wall 420 to limit the movement of the elastic element 430.

[0059] In addition, such as Figure 9 and Figure 10 As shown, a guide member 312 can also be provided on the protective cover 400 or the heating plate 300, so that the guide member 312 cooperates with the elastic member 430 to limit the elastic member 430 from stretching and deforming along the extension direction of the guide member 312. This design allows the elastic member 430 to accurately press the heating plate 300 in a set direction during assembly, which is beneficial for the heating plate 300 to be installed in place. Moreover, even if the liquid heating container falls from a platform and is bumped after assembly or during use, the elastic member 430 is not easily displaced due to the guide member 312, which helps the elastic member 430 to stably press the heating plate 300, thereby ensuring that the heating plate 300 is always in close contact with the bottom wall 110 of the container body 100.

[0060] As an example, such as Figure 9 and Figure 10 As shown, the guide member 312 can also be a guide post, which is integrally formed with the heating plate 300 or connected to it as an integral structure. The elastic member 430 is a spring, which is sleeved on the outer periphery of the guide post. Alternatively, the guide member 312 can be a sleeve, with the elastic member 430 being a spring, which partially extends into the sleeve.

[0061] Of course, the liquid heating container may also omit the elastic element 430, and instead use a protective cover 400 to directly press the heating plate 300 against the bottom wall 110 of the container. In this case, to prevent the heating plate 300 from moving horizontally, the protective cover 400 and the heating plate 300 can be fitted with a concave-convex structure, such as a limit post on the protective cover 400 and a limit groove on the heating plate 300 that matches the limit post.

[0062] Furthermore, in some embodiments, the protective cover 400 is a reflector or a heat shield.

[0063] In these embodiments, the protective cover 400 can be a reflector, which reduces the outward transmission of heat radiation by reflecting the heat radiation generated by the heating element 320. This prevents melting of the outer components of the protective cover 400 and also helps to reflect the heat radiation back to the container body 100, improving the heating efficiency of the heating plate 300. The protective cover 400 can also be a heat insulation cover, which can block heat and reduce the outward transmission of heat radiation from the heating plate 300, thereby preventing damage to the components of the protective cover 400 due to high temperatures.

[0064] Furthermore, in some embodiments, the mounting bracket 200 is a plastic bracket. It is lightweight and low-cost. Moreover, because the mounting bracket 200 has a through-hole 210 into which the heating plate 300 extends, and because there is an assembly gap between the heating plate 300 and the mounting bracket 200, the heating plate 300 does not directly transfer heat to the mounting bracket 200, thus preventing the mounting bracket 200 from melting. Especially when a portion of the protective cover 400 also extends into the through-hole 210, the protective cover 400, in conjunction with heat insulation, can further prevent the mounting bracket 200 from deforming due to high temperatures.

[0065] Regarding the connection between the container bottom cover 700 and the fixing frame 200, in some embodiments, the container bottom cover 700 is fixed to the fixing frame 200 by a first screw. The connection between the two is secure.

[0066] Furthermore, in some embodiments, such as Figures 3 to 6 , Figure 8 and Figure 9 As shown, the bottom of the mounting bracket 200 has a vertically extending threaded post 230, and the container bottom cover 700 has a mounting post 720. The first screw passes through the mounting post 720 and is inserted into the threaded post 230. The threaded post 230 on the mounting bracket 200 prevents damage to the mounting bracket 200 during the tightening of the first screw, increases the tightening depth of the first screw, and improves the connection stability between the mounting bracket 200 and the container bottom cover 700. Similarly, the mounting post 720 on the container bottom cover 700 also prevents damage to the container bottom cover 700 during the tightening of the first screw.

[0067] Furthermore, in some embodiments, such as Figures 2 to 5 , Figure 8 and Figure 9 As shown, the bottom wall 420 of the protective cover 400 is provided with an opening 421, and the liquid heating container also includes a temperature controller 500, which is fixedly connected to the bottom of the heating plate 300 through the opening 421.

[0068] In these embodiments, an opening 421 is provided on the protective cover 400 to facilitate the thermostat 500 in monitoring the temperature of the heating plate 300. Moreover, by fixing the thermostat 500 to the bottom of the heating plate 300, there is no need to provide a support structure on the container bottom cover 700 to support the thermostat 500, which simplifies the structure of the container bottom cover 700 and facilitates its manufacturing.

[0069] Furthermore, the thermostat 500 can be fixed to the heating plate 300 by a second screw. The connection between the two is secure.

[0070] As an example, such as Figure 4 , Figure 5 and Figure 9 As shown, the heating plate 300 includes a plate body 310 and a heating tube 320 located at the bottom of the plate body 310. The heating tube 320 is distributed circumferentially around the center line perpendicular to the plate body 310. The bottom of the plate body 310 may also be provided with a plate body threaded post 311. A second screw passes through the thermostat 500 and is inserted into the plate body threaded post 311, which can realize the fixed connection between the thermostat 500 and the plate body 310 and ensure that the two fit tightly.

[0071] Furthermore, such as Figure 4 , Figure 5 and Figure 7 As shown, the bottom wall 420 of the cover has upward-protruding ribs 422 on the surrounding walls of the opening 421, and the ribs 422 surround the outer periphery of the thermostat 500. The ribs 422 can block the heat radiation from the heating element 320 to the thermostat 500, which helps the thermostat 500 to accurately detect the temperature of the plate 310 without being affected by the heating element 320.

[0072] Of course, the rib 422 can also have a notch to facilitate electrical connection between the thermostat 500 and surrounding components, such as the heating element 320.

[0073] Furthermore, in some embodiments, such as Figures 1 to 5As shown, the liquid heating container also includes: an upper coupler 600 connected to a temperature controller 500, a container bottom cover 700 having a clearance hole 710 through which the upper coupler 600 is exposed; a power base 800, with a lower coupler 810 in the middle of the upper surface of the power base 800, the container bottom cover 700 being detachably placed on the upper surface of the power base 800, and the upper coupler 600 being coupled to the lower coupler 810.

[0074] In these embodiments, the container bottom cover 700 and the power base 800 are detachable, making it convenient to remove the container body 100 and the container base separately to receive or pour liquids, while also facilitating the supply of power to the heating plate 300 and the thermostat 500.

[0075] Furthermore, the upper surface of the power base 800 is flat, which reduces the overall height of the power base 800 compared to a recessed top to accommodate the container 100.

[0076] Furthermore, in some embodiments, such as Figure 4 and Figure 6 As shown, a temperature measuring hole 240 is provided at the edge of the mounting bracket 200 away from the heating plate 300. The liquid heating container also includes a temperature measuring element, which extends into the temperature measuring hole 240 and is in contact with the bottom wall of the container body 100. The temperature measuring element is in contact with the bottom wall of the container body 100 away from the heating plate 300, ensuring accurate temperature measurement.

[0077] Furthermore, in some embodiments, such as Figure 6 As shown, the fixing frame 200 can be ring-shaped. During assembly, the tooling can be arranged concentrically with the bottom wall of the container body 100. This makes it convenient for the heating plate 300, which can be inserted into the through hole 210 of the fixing frame 200, to also be arranged concentrically with the bottom wall of the container body 100, so that the heating plate 300 can evenly heat the container body 100.

[0078] Furthermore, in some embodiments, the container body 100 can be a glass container or a stainless steel container.

[0079] Furthermore, in some embodiments, the liquid heating container can be an electric kettle, a health pot, or a teapot, etc.

[0080] 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.
