Description

Technical Field

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

[0002] Current liquid heating containers typically consist of two parts: a container body and a power base. The top of the power base has a recess into which the bottom of the container body is placed. The power base contains a heating element that heats the container body, but this results in a relatively high power base. Alternatively, some related technologies have solutions that fix the heating element to the bottom of the container body, but this also results in a relatively high bottom component, leading to an overall high height for the liquid heating container. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a liquid heating container that can reduce the height occupied by the bottom component of the container body, thereby helping to reduce the overall height of the liquid heating container.

[0004] One embodiment of the present invention provides a liquid heating container, comprising: a container body; a fixing frame fixed to the bottom of the container body, the fixing frame having a through hole extending vertically; a heating plate extending at least partially into the through hole for heating the container body; and a protective cover connected to the fixing frame and at least covering the bottom of the heating plate, the protective cover being able to reduce the heat radiation transmitted from the heating plate to the outside of the protective cover.

[0005] The liquid heating container provided in this embodiment has a fixing frame at the bottom of the container body, allowing the heating plate to extend into the through hole of the fixing frame. This facilitates close-range heating of the liquid inside the container by the heating plate, ensuring a certain heating efficiency. Furthermore, the fixing frame and the heating plate at least partially overlap in the horizontal direction, which helps reduce the height occupied by the bottom components of the container body, thereby reducing the overall height of the liquid heating container. Moreover, connecting the protective cover to the fixing frame and at least covering the area below the heating plate prevents a large amount of heat generated by the heating plate from being transferred to the outside of the protective cover, avoiding melting or even damage to the components outside the protective cover.

[0006] Furthermore, in some embodiments, a portion of the protective cover extends into the through-hole to cover the outer periphery of the heating plate, or the protective cover extends to the outer periphery of the mounting bracket.

[0007] In these embodiments, whether the protective cover extends into the through-hole or to the outer periphery of the mounting bracket, the protective cover and the mounting bracket partially overlap in the horizontal direction. This helps to reduce the height of the bottom of the container body, thereby reducing the overall height of the liquid heating container. Furthermore, if part of the protective cover covers the outer periphery of the heating plate, the protective cover can also block the heat radiation from the heating plate to the mounting bracket, preventing melting of the mounting bracket, improving the connection stability between the mounting bracket and the container body, and thus improving the installation stability of the connected protective cover.

[0008] Furthermore, in some embodiments, a portion of the protective cover extends below the mounting bracket for connection with it. This facilitates connection between the protective cover and the mounting bracket without occupying internal space within the through-hole.

[0009] Furthermore, in some embodiments, the protective cover includes a bottom wall and a side wall, the bottom wall being located below the heating plate, and the side wall extending into the through hole to cover the outer periphery of the heating plate.

[0010] In these embodiments, the sidewalls of the protective cover extend into the through-hole, partially overlapping the mounting bracket and heating plate in the horizontal direction. This helps to reduce the overall height of the container bottom, thereby reducing the overall height of the liquid heating container. Furthermore, with the sidewalls extending into the through-hole, the size of the protective cover will not be excessive, facilitating a more rational distribution of space at the bottom of the container.

[0011] Furthermore, in some embodiments, a portion of the sidewall of the cover is bent outward to form a connecting ear, which extends to the bottom of the fixing frame and connects with the fixing frame; or the edge of the bottom wall of the cover has an outwardly protruding connecting rib, which extends to the bottom of the fixing frame and connects with the fixing frame.

[0012] In these embodiments, a portion of the sidewall of the cover can be bent outwards to connect with the fixing frame, resulting in a simple cover structure and easy processing. Alternatively, the edge of the bottom wall of the cover can have outwardly protruding connecting ribs, which connect to the fixing frame. This avoids affecting the sidewall of the cover extending into the through hole of the fixing frame and facilitates connection with the fixing frame.

[0013] Furthermore, in some embodiments, the portion of the protective cover extending below the mounting bracket is connected to the mounting bracket by screws. The connection is secure.

[0014] Furthermore, in some embodiments, a positioning post is provided at the bottom of the mounting bracket, and screws are inserted into the positioning post through the portion of the protective cover located below the mounting bracket; and / or there are multiple screws, circumferentially spaced around the center of the through hole. The design of the positioning post avoids the screws from being directly inserted into the main structure of the mounting bracket, which could cause the mounting bracket to break. In addition, using multiple screws at multiple points to connect the mounting bracket and the protective cover can improve the installation stability of the protective cover.

[0015] Furthermore, in some embodiments, the bottom wall of the protective cover is provided with an opening, and the liquid heating container also includes a temperature controller, which contacts the heating plate through the opening. This facilitates the temperature controller to detect the temperature of the heating plate.

[0016] 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 surrounding walls of the opening, extending to the side of the heating tubes near the center of the plate body. In this way, the ribs can block the heat radiation transmitted from the heating tubes to the thermostat, which helps the thermostat to accurately detect the plate body temperature without being affected by the direct heat radiation from the heating tubes.

[0017] Furthermore, in some embodiments, the protective cover is a reflector or a heat shield.

[0018] 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.

[0019] 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.

[0020] Furthermore, in some embodiments, the fixing frame is provided with an upward-facing glue applicator groove filled with sealant, the container body has a container bottom wall, and the fixing frame is fixedly connected to the container bottom wall by the sealant.

[0021] In these embodiments, the mounting bracket is securely connected to the container body using sealant. Furthermore, compared to the prior art where sealant is filled onto the heating plate, the mounting bracket has an assembly gap with the heating plate. Especially with the protective cover extending between the mounting bracket and the heating plate, the mounting bracket is less affected by the temperature of the heating plate, effectively reducing the likelihood of sealant detachment and ensuring the stability of the mounting bracket's installation.

[0022] Furthermore, in some embodiments, the heating plate is fixed to the protective cover and adheres to the bottom wall of the container. Compared to the prior art where the heating plate is fixed to the bottom wall of the container with sealant, which is prone to detachment due to sealant failure, fixing the heating plate to the protective cover in this embodiment improves the installation stability of the heating plate. Moreover, adhering the heating plate to the bottom wall of the container helps ensure the heat transfer efficiency between the two, thus ensuring the heating efficiency of the heating plate.

[0023] 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

[0034] The following will combine Figures 1 to 10 This invention introduces a liquid heating container provided by an embodiment of the present invention.

[0035] like Figures 2 to 5 , Figure 8 and Figure 9 As shown, one embodiment of the present invention provides a liquid heating container, including: a container body 100; a fixing frame 200 fixed to the bottom of the container body 100, the fixing frame 200 having a through hole 210 extending vertically; a heating plate 300, at least partially extending into the through hole 210 for heating the container body 100; and a protective cover 400 connected to the fixing frame 200 and at least covering the bottom of the heating plate 300, the protective cover 400 reducing the heat radiation transmitted from the heating plate 300 to the outside of the protective cover 400.

[0036] The liquid heating container provided in this embodiment has a fixing frame 200 at the bottom of the container body 100, allowing the heating plate 300 to extend into the through hole 210 of the fixing frame 200. This facilitates the heating plate 300 to heat the liquid inside the container body 100 at close range. Furthermore, the fixing frame 200 and the heating plate 300 at least partially overlap in the horizontal direction, which helps reduce the height occupied by the bottom components of the container body 100, thereby reducing the overall height of the liquid heating container. Moreover, connecting the protective cover 400 to the fixing frame 200 and at least covering the area below the heating plate 300 prevents a large amount of heat generated by the heating plate 300 from being transferred to the outside of the protective cover 400, avoiding melting or even damage to the outer components of the protective cover 400.

[0037] Furthermore, in some embodiments, such as Figure 8 and Figure 10 As shown, a portion of the protective cover 400 extends into the through hole 210 to cover the outer periphery of the heating plate 300, or the protective cover 400 extends to the outer periphery of the mounting bracket 200.

[0038] In these embodiments, whether the protective cover 400 extends into the through hole 210 or extends to the outer periphery of the fixing frame 200, the protective cover 400 and the fixing frame 200 partially overlap in the horizontal direction, which helps to reduce the bottom height of the container body 100 and thus reduce the overall height of the liquid heating container. Furthermore, if a portion of the protective cover 400 covers the outer periphery of the heating plate 300, the protective cover 400 can block the heat radiation from the heating plate 300 to the fixing frame 200, preventing melting of the fixing frame 200, improving the connection stability between the fixing frame 200 and the container body 100, and thus improving the installation stability of the connected protective cover 400.

[0039] Furthermore, in some embodiments, such as Figure 8 and Figure 10 As shown, a portion of the protective cover 400 extends below the mounting bracket 200 for connection with it. This facilitates the connection between the protective cover 400 and the mounting bracket 200.

[0040] As an example, such as Figure 4 , Figure 5 , Figure 8 and Figure 10 As shown, the protective cover 400 may include a bottom wall 420 and a side wall 410. The bottom wall 420 is located below the heating plate 300, and the side wall 410 extends into the through hole 210 to cover the outer periphery of the heating plate 300.

[0041] In this example, the side wall 410 of the protective cover 400 extends into the through hole 210, partially overlapping with the fixing bracket 200 and the heating plate 300 in the horizontal direction. This helps to reduce the overall height of the bottom of the container body 100, thereby reducing the overall height of the liquid heating container. Moreover, with the side wall 410 extending into the through hole 210, the size of the protective cover 400 will not be too large, which is beneficial for the reasonable distribution of space at the bottom of the container body 100.

[0042] 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 escaping through the gap between the protective cover 400 and the container body 100. Of course, a gap can also 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.

[0043] Furthermore, such as Figures 6 to 10 As shown, a portion of the sidewall 410 of the cover can be bent outward to form a connecting ear 411, which extends to the bottom of the fixing frame 200 and connects to it. The protective cover 400 has a simple structure and is easy to manufacture. The connecting ears 411 are multiple and are circumferentially spaced around the center line of the protective cover 400.

[0044] Alternatively, the bottom wall 420 of the cover can have connecting ribs (not shown in the figure) that protrude outward relative to the side wall 410 of the cover. These connecting ribs extend to the bottom of the fixing frame 200 and connect thereto. Connecting to the fixing frame 200 via these connecting ribs ensures that the side wall 410 does not interfere with the insertion of the cover 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 are ring-shaped and continuously distributed circumferentially around the center line of the protective cover 400. Multiple connecting ribs can also be used, spaced apart circumferentially around the center line of the protective cover 400.

[0045] Furthermore, the portion of the protective cover 400 extending below the mounting bracket 200 can be connected to the mounting bracket 200 via screws. The connection is secure.

[0046] As an example, such as Figures 4 to 6 , Figure 8 and Figure 10 As shown, a positioning post 250 is provided at the bottom of the fixing frame 200. The screw passes through the part of the protective cover 400 located below the fixing frame 200 and is inserted into the positioning post 250. The design of the fixing post can prevent the screw from being directly inserted into the main structure of the fixing frame 200 and causing the fixing frame 200 to break.

[0047] Furthermore, multiple screws can be used, circumferentially spaced around the center of the through hole 210. Multiple screws at multiple points connect the mounting bracket 200 and the protective cover 400, improving the installation stability of the protective cover 400.

[0048] Of course, in other embodiments, the protective cover 400 may also be threaded to the fixing bracket 200, or snap-fit ​​connected, etc., and is not limited to the above examples. For example, the outer surface of the cover sidewall 410 of the protective cover 400 has an external thread, and the inner wall of the through hole 210 of the fixing bracket 200 has an internal thread that matches the external thread.

[0049] Furthermore, in some embodiments, such as Figure 2 As shown, the bottom wall 420 of the protective cover 400 is provided with an opening 421. The liquid heating container also includes a temperature controller 500, which contacts the heating plate 300 through the opening 421. This facilitates the temperature controller 500 to detect the temperature of the heating plate 300.

[0050] Furthermore, such as Figure 2 and Figure 3 As shown, the liquid heating container also includes an upper coupler 600, which is connected to the temperature controller 500 in an integrated structure, facilitating the supply of power to the heating plate 300 and the temperature controller 500.

[0051] As an example, such as Figures 8 to 10 As shown, the bottom of the disc body 310 can also be provided with a disc body threaded post 311. The screw passes through the thermostat 500 and is inserted into the disc body threaded post 311, which can realize the fixed connection between the thermostat 500 and the disc body 310 and ensure that the two fit tightly together.

[0052] Furthermore, such as Figures 2 to 5 , Figure 7 and Figure 8 As shown, the heating plate 300 includes a plate body 310 and heating tubes 320 located at the bottom of the plate body 310. The heating tubes 320 are distributed circumferentially around the center line perpendicular to the center line of the plate body 310. The bottom wall 420 of the cover has upwardly protruding ribs 422 on the surrounding walls of the opening 421. The ribs 422 extend to the side of the heating tubes 320 near the center of the plate body 310. In this way, the ribs 422 can block the heat radiation transmitted from the heating tubes 320 to the temperature controller 500, which helps the temperature controller 500 to accurately detect the temperature of the plate body 310 without being affected by the heating tubes 320.

[0053] 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.

[0054] Furthermore, in some embodiments, the protective cover 400 is a reflector or a heat shield.

[0055] 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.

[0056] 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.

[0057] Furthermore, in some embodiments, such as Figure 3 , Figure 6 and Figure 8 As shown, the fixing frame 200 is provided with a glue-applying groove 220 with the groove opening facing upward. The glue-applying groove 220 is filled with sealant. The container body 100 has a container bottom wall 110. The fixing frame 200 is fixedly connected to the container bottom wall 110 by the sealant.

[0058] In these embodiments, the mounting bracket 200 is connected to the container body 100 via sealant, ensuring a secure connection. Furthermore, compared to the prior art where the sealant is filled onto the heating plate 300 and in direct contact with it, the mounting bracket 200 has an assembly gap with the heating plate 300. Especially with the protective cover 400 extending between the mounting bracket 200 and the heating plate 300, the sealant is less affected by the temperature of the heating plate 300, effectively reducing the likelihood of sealant detachment and ensuring the installation stability of the mounting bracket 200, thereby improving the connection stability of the heating plate 300. This embodiment changes the traditional connection method between the heating plate 300 and the container body 100, improving the durability of the sealant and preventing adverse phenomena caused by sealant aging.

[0059] Of course, the fixing frame 200 and the container body 100 can also be fixed in other ways, such as welding connection, etc., and are not limited to the above examples.

[0060] Furthermore, in some embodiments, such as Figures 4 to 6 , Figure 10As 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 fits against the container body 100. The temperature measuring element is away from the heating plate 300 and contacts the bottom wall 110 of the container body 100, ensuring accurate temperature measurement.

[0061] Regarding the connection method of the heating plate 300, further, in some embodiments, such as Figure 8 As shown, the heating plate 300 is fixed to the protective cover 400 and connected to the mounting bracket 200 via the protective cover 400. Compared to related technologies where adhesive is directly applied to the heating plate 300 to connect it to the container bottom wall 110, this design, with the heating plate 300 connected to the container bottom wall 110 via the protective cover 400 and mounting bracket 200, prevents the adhesive from falling off, thus improving the installation stability of the heating plate 300. Furthermore, since both the heating plate 300 and the protective cover 400 are fixed to the mounting bracket 200, and the mounting bracket 200 partially overlaps with the heating plate 300 and the protective cover 400 in the horizontal direction, it helps reduce the bottom height of the container body 100, thereby reducing the overall height of the liquid heating container. Moreover, compared to connecting the heating plate 300 and the protective cover 400 to the container body 100 through different parts, the machining precision of the container body 100 can be reduced, facilitating rapid machining and forming of the container body 100, and improving product qualification rate and assembly efficiency.

[0062] Furthermore, the heating plate 300 is in close contact with the bottom wall 110 of the container body 100. This helps to ensure the heat transfer efficiency between the two and ensures the heating efficiency of the heating plate 300.

[0063] Furthermore, such as Figures 8 to 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.

[0064] 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.

[0065] Moreover, by using the protective cover 400 to support the elastic element 430, not only can the heat radiation transmitted outward from the heating plate 300 be reduced, and the outer parts of the protective cover 400 be prevented from being damaged by the high temperature generated by the heating plate 300, but also the additional support structure to support the elastic element 430 can be eliminated, which can reduce the number of parts and save costs.

[0066] 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.

[0067] 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.

[0068] In addition, such as Figures 8 to 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.

[0069] As an example, such as Figures 8 to 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.

[0070] As an example, such as Figures 8 to 10 As shown, the protective cover 400 may have a bottom wall 420, and an elastic element 430 is supported between the bottom wall 420 and the heating plate 300. The elastic element 430 supports the heating plate 300 vertically, providing good support.

[0071] 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. Moreover, 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.

[0072] Furthermore, in some embodiments, such as Figure 6As shown, the fixing frame 200 is ring-shaped. During assembly, the tooling can be arranged concentrically with the container bottom wall 110 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 container bottom wall 110 of the container body 100, so that the heating plate 300 can evenly heat the container body 100.

[0073] Furthermore, in some embodiments, such as Figures 1 to 3 As shown, the liquid heating container also includes an upper coupler 600, which is integrated with the temperature controller 500. The liquid heating container also includes a container bottom cover 700, with clearance holes on the bottom cover 700 corresponding to the upper coupler 600 to allow the upper coupler 600 to be exposed. The liquid heating container also includes a power base 800, which has a lower coupler 810. The lower coupler 810 can be coupled to the upper coupler 600 to supply power to the heating plate 300 and the temperature controller 500. The container bottom cover 700 is detachably placed on the power base 800.

[0074] The upper surface of the power base 800 can be flat, facilitating the placement and removal of the container bottom cover 700 and the container body 100. Moreover, compared to the recessed upper part of the power base 800, the container bottom cover 700 is partially sunken into the recess, which can reduce the overall height of the power base 800.

[0075] Furthermore, such as Figure 5 , Figure 6 and Figure 10 As shown, the container bottom cover 700 is provided with mounting posts, and the bottom of the fixing bracket 200 is provided with threaded posts 230 corresponding to the positions of the mounting posts. Screws pass through the mounting posts and are inserted into the threaded posts 230 to fix the container bottom cover 700. The container bottom cover 700 is firmly connected. Moreover, fixing the container bottom cover 700 to the fixing bracket 200, compared to directly connecting the container bottom cover 700 to the container body 100, simplifies the machining accuracy of the container body 100 and makes the machining of the container body 100 more convenient.

[0076] Furthermore, in some embodiments, the container body 100 can be a glass container or a stainless steel container.

[0077] Furthermore, in some embodiments, the liquid heating container can be an electric kettle, a health pot, or a teapot, etc.

[0078] 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.
