Description

Technical Field

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

[0002] In current liquid heating containers, the bottom of the container body is usually open, and the edge of the heating plate is equipped with a glue-applying groove. The bottom of the container body is inserted into the glue-applying groove, and glue is injected into the groove to seal the opening, thus forming a sealed cavity capable of holding liquid. However, because the glue is inside the heating plate and is in long-term contact with the liquid inside the container, there is a significant risk of it detaching, which could cause the heating plate to fall off, posing a safety hazard. Utility Model Content

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

[0004] One embodiment of this utility model 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 running vertically through it; a heating plate extending into the through hole and fitting against the bottom wall of the container body; a protective cover connected to the fixing frame and at least covering the bottom of the heating plate, the protective cover reducing the heat radiation transmitted from the heating plate to the outside of the protective cover; and an elastic member sandwiched between the protective cover and the heating plate to press the heating plate against the outer surface of the bottom wall of the container body.

[0005] The liquid heating container provided in this embodiment connects the fixing frame to the bottom of the container body and the protective cover to the fixing frame. An elastic element is provided between the protective cover and the heating plate. The elastic element presses the heating plate against the bottom wall of the container body. On the one hand, this ensures that the heating plate and the container body are fully fitted, thereby ensuring the heating effect of the heating plate. On the other hand, it eliminates the need to apply glue to the heating plate to connect it to the container body, thereby avoiding the heating plate from falling off due to glue failure and improving the installation stability of the heating plate.

[0006] Furthermore, by using a protective cover to support the elastic component, the heat radiation transmitted outward from the heating plate can be reduced, preventing damage to the outer components of the protective cover due to the high temperature generated by the heating plate. In addition, it eliminates the need for additional support structures to support the elastic component, reducing the number of parts and saving costs.

[0007] Furthermore, in some embodiments, a portion of the protective cover extends into the through-hole and surrounds the outer periphery of the heating plate.

[0008] In these embodiments, the protective cover can also block the heat radiation from the heating plate to the mounting bracket, which can prevent the mounting bracket from melting, improve the connection stability between the mounting bracket and the container body, and thus improve the installation stability of the protective cover and elastic element connected thereto.

[0009] Furthermore, in some embodiments, the protective cover includes a bottom wall and side walls distributed circumferentially along the outer edge of the bottom wall, at least a portion of which extends into the through hole and surrounds the outer periphery of the heating plate.

[0010] In these embodiments, the sidewall of the protective cover extends 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. Moreover, by having the sidewall of the protective cover extend into the through hole, the size of the protective cover will not be too large, which is beneficial for the reasonable distribution of space at the bottom of the container.

[0011] 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.

[0012] 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, and the ribs extend to the side of the heating tubes near the center of the plate body.

[0013] 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.

[0014] Furthermore, in some embodiments, the protective cover is a reflector or a heat shield.

[0015] 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.

[0016] 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.

[0017] Furthermore, in some embodiments, the elastic element is a spring, and / or there are multiple elastic elements, which are circumferentially spaced around the center line perpendicular to the heating plate.

[0018] In these embodiments, the elastic element can be a spring, which has good elasticity and high temperature resistance. There are multiple elastic elements, which are circumferentially distributed around the center line perpendicular to the heating plate. This allows the elastic elements to fully support the heating plate at multiple points, ensuring that the heating plate is fully in contact with the bottom wall of the container, thereby guaranteeing the heating effect.

[0019] Furthermore, in some embodiments, the liquid heating container further includes a guide member disposed on the protective cover or heating plate. The guide member cooperates with the elastic member to limit the elastic member's expansion and contraction along the extension direction of the guide member. The guide member's design allows the elastic member to accurately press the heating plate along a set direction during installation, facilitating proper installation of the heating plate. Moreover, even if the liquid heating container tilts or is bumped, the elastic member will not detach from the guide member, ensuring stable pressure on the heating plate and guaranteeing that the heating plate remains tightly fitted to the bottom wall of the container.

[0020] 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 of the container body by the sealant.

[0021] In these embodiments, the mounting bracket is securely connected to the container body via sealant. Furthermore, compared to the prior art where the 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 sealant on the mounting bracket is less affected by the temperature of the heating plate, effectively reducing the chance of sealant detachment and ensuring the installation stability of the mounting bracket.

[0022] Furthermore, in some embodiments, a temperature measuring hole is provided at the edge of the mounting bracket away from the heating plate, and the liquid heating container also includes a temperature measuring element that extends into the temperature measuring hole and fits against the bottom wall of the container. Since the temperature measuring element is in contact with the bottom wall of the container away from the heating plate, the temperature measurement is accurate.

[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 11 This invention introduces a liquid heating container provided by an embodiment of the present invention.

[0035] like Figures 2 to 6 , Figure 9 and Figure 10 As shown, one embodiment of the present invention provides a liquid heating container, comprising: 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 extending into the through hole 210 and fitting against the bottom wall 110 of the container body 100; 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; and an elastic member 430 sandwiched between the protective cover 400 and the heating plate 300 to press the heating plate 300 against the outer surface of the bottom wall 110 of the container body 100.

[0036] The liquid heating container provided in this embodiment allows the heating plate 300 to press against the outer surface of the bottom wall 110 of the container body 100. Here, it is assumed that the container body 100 has a bottom wall 110, which, compared to an open bottom, prevents water leakage from the bottom of the container body 100. Furthermore, by connecting the fixing bracket 200 to the bottom of the container body 100 and the protective cover 400 to the fixing bracket 200, and by providing an elastic element 430 between the protective cover 400 and the heating plate 300, the heating plate 300 is pressed against the bottom wall 110 of the container body 100. This ensures that the heating plate 300 and the container body 100 are fully fitted, thus guaranteeing the heating effect of the heating plate 300. It also eliminates the need for adhesive to connect the heating plate 300 to the container body 100, preventing the heating plate 300 from detaching due to adhesive failure and improving the installation stability of the heating plate 300.

[0037] 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.

[0038] In addition, the through hole 210 provided on the fixing frame 200 allows the heating plate 300 to extend into it. The two partially overlap in the horizontal direction, which also helps to reduce the overall height of the bottom of the container body 100, thereby reducing the overall height of the liquid heating container.

[0039] Furthermore, such as Figure 9 and Figure 10 As shown, 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 of other structures.

[0040] Furthermore, such as Figure 6 As shown, 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 the 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.

[0041] Furthermore, such as Figure 5 , Figures 9 to 11As 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. In this way, the elastic member 430 can accurately press the heating plate 300 in a set direction during the assembly process, which is conducive to the proper installation of the heating plate 300. 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 easy to displace due to the guide member 312, which is conducive to the stable pressing of the heating plate 300 by the elastic member 430, thereby ensuring that the heating plate 300 is always in close contact with the bottom wall 110 of the container body 100.

[0042] As an example, such as Figure 5 , Figures 9 to 11 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.

[0043] Furthermore, such as Figure 6 and Figure 9 As shown, the protective cover 400 can 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. Furthermore, to prevent the elastic element 430 from shifting, the end of the elastic element 430 away from the heating plate 300 can be fixedly connected to the bottom wall 420. Of course, as... Figure 6 As shown, a limiting member 423 can also be provided on the bottom wall 420 of the cover to limit the elastic member 430, such as the guide member 312 or other limiting structures.

[0044] Regarding the connection method between the mounting bracket 200 and the protective cover 400, further, in some embodiments, such as Figures 9 to 11 As shown, a portion of the protective cover 400 extends into the through hole 210 and surrounds 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.

[0045] In these embodiments, the protective cover 400 can also block the heat radiation from the heating plate 300 to the fixing frame 200, which can prevent the fixing frame 200 from melting, improve the connection stability between the fixing frame 200 and the container body 100, and thus improve the installation stability of the protective cover 400 and the elastic element 430 connected thereto.

[0046] In addition, a portion of the protective cover 400 extends to the bottom of the bracket 200 and connects to the bracket 200, which facilitates connection and does not occupy the internal space of the through hole 210.

[0047] Furthermore, such as Figure 8 and Figure 11 As shown, the protective cover 400 may include a bottom wall 420 and side walls 410 distributed circumferentially along the outer edge of the bottom wall 420, with at least a portion of the side walls 410 extending into the through hole 210 and surrounding the outer periphery of the heating plate 300. By having the side walls 410 of the protective cover 400 extend into the through hole 210 and partially overlap with the fixing frame 200 and the heating plate 300 in the horizontal direction, it is beneficial to reduce the overall height of the bottom of the container body 100, thereby reducing the overall height of the liquid heating container. Furthermore, by having the side walls of the protective cover 400 extend into the through hole 210, the size of the protective cover 400 will not be excessive, which is beneficial for the reasonable distribution of space at the bottom of the container body 100.

[0048] 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.

[0049] 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 between the two is secure.

[0050] As an example, such as Figure 4 , Figure 5 , Figures 7 to 11 As shown, a positioning post 250 is provided at the bottom of the fixing bracket 200, and a part of the side wall 410 of the protective cover 400 is bent outward to form a connecting ear 411. The screw passes through the connecting ear 411 and is inserted into the positioning post 250.

[0051] As an example, the protective cover 400 includes a side wall 410 and a bottom wall 420. The outer edge of the bottom wall 420 protrudes from the side wall 410 to form a connecting rib (not shown in the figure). Screws pass through the connecting rib and are inserted into the fixing frame 200.

[0052] Of course, the protective cover 400 and the fixing frame 200 can also have other connection methods. For example, the part of the protective cover 400 that extends into the bottom of the fixing frame 200 can be connected to the fixing frame 200 by a snap-fit, or the protective cover 400 and the fixing frame 200 can be connected by a thread, etc., which will not be listed in detail here.

[0053] Furthermore, in some embodiments, such as Figure 6 As shown, the bottom wall 420 of the protective cover 400 may be 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 design facilitates the temperature controller 500 to detect the temperature of the heating plate 300.

[0054] Furthermore, such as Figure 5 , Figure 6 , Figure 8 and Figure 11 As shown, the heating plate 300 may include 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 may have upwardly protruding ribs 422 on the surrounding wall surface of the opening 421. The ribs 422 extend to the side of the heating tubes 320 near the center of the plate body 310. 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.

[0055] 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.

[0056] Furthermore, such as Figure 5 and Figure 11 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.

[0057] Furthermore, the liquid heating container also includes an upper coupler 600, which is integrated with the temperature controller 500 to facilitate power supply to the heating plate 300 and the temperature controller 500.

[0058] Furthermore, in some embodiments, the protective cover 400 is a reflector or a heat shield.

[0059] 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 100, improving the heating efficiency of the heating plate 300. Of course, 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.

[0060] 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, they are not directly connected, 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.

[0061] Furthermore, in some embodiments, such as Figure 3 , Figure 7 and Figure 9 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 of the container body 100 by the sealant.

[0062] 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 application 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.

[0063] Of course, the mounting bracket 200 can also be connected to the container body 100 in other ways, such as by welding, and is not limited to the examples above.

[0064] Furthermore, in some embodiments, such as Figure 5 and Figure 7 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 (not shown in the figure), which extends into the temperature measuring hole 240 and is in contact with the bottom wall 110 of the container body 100. The temperature measuring element is in contact with the bottom wall 110 of the container body 100 away from the heating plate 300, ensuring accurate temperature measurement.

[0065] Furthermore, in some embodiments, such as Figure 5 and Figure 7As shown, the fixing frame 200 is ring-shaped. During assembly, the tooling can be arranged concentrically with the 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 bottom wall 110 of the container body 100, so that the heating plate 300 can evenly heat the container body 100.

[0066] Furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 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.

[0067] 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.

[0068] Furthermore, such as Figure 4 , Figure 5 and Figure 11 As shown, a mounting post can be provided on the container bottom cover 700. A threaded post 230 is provided on the bottom of the fixing bracket 200 corresponding to the position of the mounting post. Screws pass through the mounting post and are inserted into the threaded post 230 to fix the container bottom cover 700. The container bottom cover 700 is securely connected. Furthermore, fixing the container bottom cover 700 to the fixing bracket 200 simplifies the machining accuracy of the container body 100 compared to directly connecting the container bottom cover 700 to the container body 100, making the machining of the container body 100 easier.

[0069] Furthermore, in some embodiments, the container body 100 can be a glass container or a stainless steel container.

[0070] Furthermore, in some embodiments, the liquid heating container can be an electric kettle, a health pot, or a teapot, etc.

[0071] 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.
