Description

Technical Field

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

[0002] Liquid heating containers typically include a body, a bottom lid, and a heating plate, with the heating plate fixedly installed between the body and the bottom lid. In existing technology, positioning ribs are usually provided on the inner wall of the body to limit the heating plate's axial movement. However, the structure of these positioning ribs easily traps dirt and grime, making daily cleaning inconvenient for users. Utility Model Content

[0003] This application provides a liquid heating container that solves the problem of inconvenient cleaning of the body of liquid heating containers in the prior art.

[0004] This application provides a liquid heating container, comprising: a body with an inner sidewall having a receiving groove, the receiving groove having a first sidewall; a heating plate with a flange extending radially away from the center of the heating plate, at least a portion of the flange being located within the receiving groove; and a bottom cover fixedly connected to the body, the bottom cover having a supporting rib, the flange being clamped between the first sidewall and the supporting rib along the axial direction of the liquid heating container.

[0005] In the above solution, when the heating plate is assembled with the kettle body and bottom cover, at least a portion of the flange is located within the receiving groove. At this time, along the axial direction of the liquid heating container, the flange can be clamped between the first sidewall and the supporting rib, thereby restricting the axial movement of the heating plate within the liquid heating container and achieving a fixed installation of the heating plate. In the radial direction of the liquid heating container, the second sidewall can limit the flange's movement, further restricting the radial movement of the heating plate and improving its installation stability. Furthermore, the supporting rib can also provide support from below the heating plate, further enhancing its installation stability. Compared with the existing technology of setting positioning ribs on the inner wall of the kettle body to fix the heating plate, this application adopts the method of opening a receiving groove on the inner wall of the kettle body and using the first side wall of the receiving groove to cooperate with the supporting ribs to fix the heating plate. This can reduce the dead corners inside the kettle body, facilitate daily cleaning by users, reduce the risk of bacterial growth, improve the user experience, improve the safety of drinking water, and simplify the internal structure of the kettle body. It is also conducive to improving the production efficiency of liquid heating containers and reducing the production difficulty and cost of liquid heating containers.

[0006] In one possible design, the liquid heating container further includes a sealing ring mounted on the flange; the sealing ring includes a main body portion, at least a portion of which is located within the receiving groove, and along the axial direction of the liquid heating container, the main body portion is clamped between the first sidewall and the flange.

[0007] In the above solution, the sealing ring acts as a seal between the inner wall of the kettle body and the heating plate, preventing liquid in the first cavity from flowing towards the bottom cover. The main body is clamped between the first side wall and the flange, restricting the axial movement of the sealing ring in the liquid heating container and improving the installation stability of the sealing ring.

[0008] In one possible design, a groove is provided at the end of the first sidewall away from the center of the vessel body along the radial direction of the liquid heating container.

[0009] In the above design, the groove provides space for the deformation of the sealing ring, allowing it to deform more easily. This enables the sealing ring to adhere tightly to the kettle body and heating plate under its own restoring force, thereby improving the sealing effect. By providing deformation space for the sealing ring through the groove, the friction between the sealing ring and the first sidewall can also be reduced, lowering the wear rate and thus helping to extend the service life of the sealing ring.

[0010] In one possible design, the sealing ring further includes an extension fixedly connected to the main body, the extension extending axially along the liquid heating container; the receiving groove also has a second sidewall radially along the liquid heating container, the extension being clamped between the second sidewall and the flange.

[0011] In the above solution, when the sealing ring is installed on the flange, the extension can be held radially between the second side wall and the flange of the liquid heating container, filling the gap between the second side wall and the flange, thereby improving the sealing performance of the sealing ring and further improving the sealing effect between the kettle body and the heating plate.

[0012] In one possible design, an installation space is formed between the sidewall of the bottom cover and the supporting rib along the radial direction of the liquid heating container; at least a portion of the sidewall of the vessel body is located within the installation space.

[0013] In the above solution, the side wall of the bottom cover and the supporting ribs can limit the body of the pot in the radial direction of the liquid heating container, thereby improving the installation stability between the pot body and the bottom cover.

[0014] In one possible design, the bottom cover is provided with a snap-fit ​​part, and the body of the pot is provided with a snap-fit ​​mating part, wherein the snap-fit ​​part and the snap-fit ​​mating part are snapped together and fixed.

[0015] In the above scheme, the snap-fit ​​connection method has a relatively simple structure and is detachable, making it more convenient for installation and maintenance.

[0016] In one possible design, the snap-fit ​​portion includes a first snap-fit ​​portion disposed on the inner side wall of the bottom cover, protruding towards the center of the bottom cover along the radial direction of the liquid heating container; the snap-fit ​​mating portion includes a snap-fit ​​groove located on the outer side wall of the vessel body, and the first snap-fit ​​portion is snapped and fixed to the snap-fit ​​groove.

[0017] In the above solution, the snap-fit ​​groove can simultaneously limit the first snap-fit ​​part in the axial direction and circumferential direction of the liquid heating container, thereby improving the fixed connection effect between the kettle body and the bottom cover.

[0018] In one possible design, the outer wall of the kettle body is further provided with a support portion, which is located below the snap-fit ​​groove; at least a portion of the first snap-fit ​​portion overlaps with the support portion.

[0019] In the above solution, the support part can provide support and limit the first snap-fit ​​part, which helps to improve the connection reliability between the first snap-fit ​​part and the snap-fit ​​groove, thereby improving the connection stability between the kettle body and the bottom cover.

[0020] In one possible design, the snap-fit ​​portion further includes a second snap-fit ​​portion, which is fixedly connected to the support rib and protrudes in a direction away from the center of the bottom cover along the radial direction of the liquid heating container; the snap-fit ​​mating portion includes a connecting hole located on the side wall of the kettle body, and the second snap-fit ​​portion is snapped and fixed to the connecting hole.

[0021] In the above solution, the kettle body and the bottom cover can be fixedly connected by the snap-fit ​​of the second snap-fit ​​part and the connecting hole. The connecting hole can limit the second snap-fit ​​part in both the axial direction and the circumferential direction of the liquid heating container, thereby improving the fixed connection effect between the kettle body and the bottom cover.

[0022] In one possible design, the outer wall of the vessel body is provided with a limiting step, which abuts against the top wall of the bottom cover along the axial direction of the liquid heating container.

[0023] In the above scheme, the limiting step and the top wall of the bottom cover abut against each other along the axial direction of the liquid heating container to restrict the relative movement between the kettle body and the bottom cover along the axial direction of the liquid heating container. At the same time, the bottom cover can provide support for the kettle body, which helps to improve the installation stability of the kettle body.

[0024] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0054] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0055] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0056] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0057] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0058] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0059] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0060] This application provides a liquid heating container, such as... Figure 1As shown, the liquid heating container includes a body 1, a heating plate 2, and a bottom cover 3, with the body 1 and bottom cover 3 fixedly connected. The heating plate 2 is disposed between the body 1 and the bottom cover 3, forming a first cavity 16 for containing liquid, which the heating plate 2 heats. The bottom cover 3 and the heating plate 2 form a second cavity 36 for housing various electrical components. The liquid heating container also includes a base 5, which is electrically connected to the bottom cover 3 to supply power to the heating plate 2 and the electrical components inside the bottom cover 3.

[0061] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the kettle body 1 is provided with a receiving groove 11, which has a first side wall 111 and a second side wall 112. The bottom cover 3 includes a cover body 35 and a supporting rib 31 disposed within the cover body 35. The bottom of the supporting rib 31 is fixedly connected to the inner bottom wall of the cover body 35 and extends along the axial direction Z of the liquid heating container. The heating plate 2 is provided with a flange 21, which extends along the radial direction X of the liquid heating container in a direction away from the center of the heating plate 2. When the heating plate 2 is assembled with the kettle body 1 and the bottom cover 3, at least a portion of the flange 21 is located within the receiving groove 11. At this time, along the axial direction Z of the liquid heating container, the flange 21 can be clamped between the first side wall 111 and the supporting rib 31, thereby restricting the movement of the heating plate 2 in the axial direction Z of the liquid heating container and realizing the fixed installation of the heating plate 2. In the radial direction X of the liquid heating container, the second sidewall 112 can limit the movement of the flange 21, thereby restricting the movement of the heating plate 2 in the radial direction X of the liquid heating container and improving the installation stability of the heating plate 2. Furthermore, the supporting rib 31 can also provide support below the heating plate 2, further enhancing the installation stability of the heating plate 2.

[0062] Compared with the existing technology of setting positioning ribs on the inner side wall of the kettle body 1 to fix the heating plate 2, the embodiment of this application adopts the method of opening a receiving groove 11 on the inner side wall of the kettle body 1 and using the first side wall 111 of the receiving groove 11 to cooperate with the supporting rib 31 to fix the heating plate 2. This can reduce the dead corners of hygiene inside the kettle body 1, facilitate daily cleaning by users, reduce the risk of bacterial growth, improve the user experience, improve the safety of drinking water, and simplify the internal structure of the kettle body 1. This is conducive to improving the production efficiency of liquid heating containers and reducing the production difficulty and production cost of liquid heating containers.

[0063] In this embodiment, the supporting ribs 31 and the cover 35 can be an integral structure or a separate structure, and this embodiment does not impose any restrictions on this. The bottom cover 3 can be provided with multiple supporting ribs 31, which can be evenly distributed in the circumferential direction of the cover 35 or unevenly distributed in the circumferential direction of the cover 35, and this embodiment does not impose any restrictions on this.

[0064] In one specific implementation, such as Figure 3 As shown, multiple support rib groups can be evenly spaced along the circumference of the cover 35, with each pair of support ribs 31 forming a support rib group. This helps to improve the support effect of the support ribs 31 on the heating plate 2, ensures that the heating plate 2 can be evenly stressed along the circumference of the cover 35, and reduces the risk of stress concentration at the contact point between the heating plate 2 and the support ribs 31.

[0065] In one specific embodiment, the liquid heating container may further include a sealing ring 4, which is installed on the flange 21 to provide a seal between the inner wall of the vessel body 1 and the heating plate 2, preventing liquid in the first cavity 16 from flowing to the bottom cover 3. Figure 2 As shown, the sealing ring 4 includes a main body 41. When the sealing ring 4 is installed on the flange 21, at least a portion of the main body 41 is located within the receiving groove 11. Along the axial direction Z of the liquid heating container, the main body 41 can be clamped between the first side wall 111 and the flange 21, thereby restricting the movement of the sealing ring 4 in the axial direction Z of the liquid heating container and improving the installation stability of the sealing ring 4. Moreover, along the radial direction X of the liquid heating container, both sides of the main body 41 can respectively abut against the second side wall 112 and the heating plate 2, which is beneficial to the sealing effect between the pot body 1 and the heating plate 2.

[0066] like Figure 2 As shown, the sealing ring 4 may be provided with an extension 42 fixedly connected to the main body 41. The extension 42 is arranged circumferentially along the main body 41 and extends downward along the axial direction Z of the liquid heating container. When the sealing ring 4 is installed on the flange 21, the extension 42 can be clamped between the second side wall 112 and the flange 21 along the radial direction X of the liquid heating container, filling the gap between the second side wall 112 and the flange 21, thereby improving the sealing performance of the sealing ring 4 and further improving the sealing effect between the kettle body 1 and the heating plate 2.

[0067] In this embodiment, the sealing ring 4 can also act as a buffer between the kettle body 1 and the heating plate 2, reducing the risk of wear between the kettle body 1 and the heating plate 2 due to mutual friction during assembly and daily use, which is beneficial to improving the service life of the liquid heating container.

[0068] In one specific implementation, such as Figure 2As shown, along the radial direction X of the liquid heating container, a groove 111a is provided at the end of the first sidewall 111 furthest from the center of the pot body 1. The groove 111a provides space for the deformation of the sealing ring 4, facilitating a larger deformation of the sealing ring 4. This allows the sealing ring 4 to adhere tightly to the pot body 1 and the heating plate 2 under its own restoring force, thereby improving the sealing effect of the sealing ring 4. By providing deformation space for the sealing ring 4 through the groove 111a, the friction between the sealing ring 4 and the first sidewall 111 can also be reduced, lowering the wear rate and thus helping to extend the service life of the sealing ring 4.

[0069] In one specific implementation, such as Figure 5 As shown, an installation space 32 is formed between the side wall of the lid 35 and the supporting rib 31. When the kettle body 1 is connected to the bottom cover 3, at least a portion of the side wall of the kettle body 1 can extend into the installation space 32. At this time, the side wall of the lid 35 and the supporting rib 31 can limit the kettle body 1 in the radial direction X of the liquid heating container, thereby improving the installation stability between the kettle body 1 and the bottom cover 3.

[0070] In this embodiment, the connection between the kettle body 1 and the bottom cover 3 can be achieved by adhesive bonding, snap-fitting, or bolting. Preferably, the kettle body 1 and the bottom cover 3 are connected by snap-fitting, as snap-fitting is easier to operate and can be disassembled compared to adhesive bonding, facilitating maintenance. Snap-fitting is also easier to assemble and disassemble than bolting. Specifically, a snap-fitting part can be provided on the bottom cover 3, and a snap-fitting mating part can be provided on the kettle body 1. The fixed connection between the kettle body 1 and the bottom cover 3 is achieved through the snap-fitting fixation between the snap-fitting part and the snap-fitting mating part.

[0071] In one specific implementation, such as Figure 4 As shown, the snap-fit ​​portion includes a first snap-fit ​​portion 33, which is disposed on the inner sidewall of the cover 35. Along the radial direction X of the liquid heating container, the first snap-fit ​​portion 33 protrudes towards the center of the bottom cover 3. Figure 5 As shown, the snap-fit ​​part includes a snap-fit ​​groove 12, which is located on the outer side wall of the kettle body 1. The kettle body 1 and the bottom cover 3 can be fixedly connected by the snap-fit ​​of the first snap-fit ​​part 33 and the snap-fit ​​groove 12. The snap-fit ​​groove 12 can limit the first snap-fit ​​part 33 in both the axial Z direction and the circumferential direction of the liquid heating container, thereby improving the fixed connection effect between the kettle body 1 and the bottom cover 3.

[0072] Furthermore, a support portion 13 can be provided on the outer wall of the kettle body 1, located below the snap-fit ​​groove 12. When the first snap-fit ​​portion 33 snaps into the snap-fit ​​groove 12, at least a portion of the first snap-fit ​​portion 33 can overlap the support portion 13. The support portion 13 can provide a supporting and limiting effect on the first snap-fit ​​portion 33, which helps to improve the connection reliability between the first snap-fit ​​portion 33 and the snap-fit ​​groove 12, thereby improving the connection stability between the kettle body 1 and the bottom cover 3. The surface of the support portion 13 facing the cover 35 can be set as an inclined surface. The inclined surface can form a guiding engagement with the first snap-fit ​​portion 33 during the installation of the kettle body 1 and the bottom cover 3, thereby improving the assembly efficiency between the kettle body 1 and the bottom cover 3.

[0073] In another specific implementation, such as Figure 4 As shown, the snap-fit ​​portion also includes a second snap-fit ​​portion 34, which is fixedly connected to the support rib 31. Along the radial direction X of the liquid heating container, the second snap-fit ​​portion 34 protrudes in a direction away from the center of the bottom cover 3. Figure 5 As shown, the snap-fit ​​part includes a connecting hole 14, which is located on the side wall of the kettle body 1. The second snap-fit ​​part 34 is snapped and fixed to the connecting hole 14. Figure 2 As shown, the kettle body 1 and the bottom cover 3 can be fixedly connected by the snap-fit ​​of the second snap-fit ​​part 34 and the connecting hole 14. The connecting hole 14 can simultaneously limit the second snap-fit ​​part 34 in the axial Z direction and the circumferential direction of the liquid heating container, thereby improving the fixed connection effect between the kettle body 1 and the bottom cover 3. The surface of the second snap-fit ​​part 34 facing the kettle body 1 can be set as a slope. The slope can form a guide and fit with the side wall of the kettle body 1 during the installation of the kettle body 1 and the bottom cover 3, thereby improving the assembly efficiency between the kettle body 1 and the bottom cover 3.

[0074] In this embodiment, the kettle body 1 and the bottom cover 3 are fixedly connected by multiple snap-fit ​​parts and multiple snap-fit ​​mating parts. Specifically, the multiple snap-fit ​​parts and multiple snap-fit ​​mating parts can all be first snap-fit ​​parts 33 and snap-fit ​​grooves 12, or all be second snap-fit ​​parts 34 and connecting holes 14, or partly be first snap-fit ​​parts 33 and snap-fit ​​grooves 12 and the other part be second snap-fit ​​parts 34 and connecting holes 14. This embodiment does not limit the specific configuration. Preferably, the multiple snap-fit ​​parts and multiple snap-fit ​​mating parts are configured such that partly are first snap-fit ​​parts 33 and snap-fit ​​grooves 12 and the other part are second snap-fit ​​parts 34 and connecting holes 14. This ensures that the kettle body 1 is fixedly connected to both the lid 35 and the supporting rib 31, which helps improve the reliability of the connection between the kettle body 1 and the bottom cover 3.

[0075] In one specific embodiment, the outer side wall of the kettle body 1 may also be provided with a limiting step 15. When the kettle body 1 is connected to the bottom cover 3, the limiting step 15 can abut against the top wall of the cover 35 along the axial direction Z of the liquid heating container to restrict the relative movement of the kettle body 1 and the bottom cover 3 along the axial direction Z of the liquid heating container. At the same time, the bottom cover 3 can provide support for the kettle body 1, which is beneficial to improving the installation stability of the kettle body 1.

[0076] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
