Description

Technical Field

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

[0002] Some existing liquid heating containers adopt IH heating technology (electromagnetic heating technology) to improve the heating efficiency, that is, a magnetic conductive sheet is provided at the bottom of the inner liner of the kettle body, and an electromagnetic heating element is provided on the base, and the heating function of the liquid heating container is realized through electromagnetic induction between the magnetic conductive sheet and the electromagnetic heating element.

[0003] However, the existing magnetic conductive sheet and the bottom of the inner liner are fixedly connected by bonding, and there are easily non-fitting parts between the magnetic conductive sheet and the bottom of the inner liner, resulting in low heat transfer efficiency from the magnetic conductive sheet to the inner liner, which affects the heating efficiency of the liquid heating container. Summary of the Utility Model

[0004] This application provides a liquid heating container, which can solve the problem of low heat transfer efficiency from the magnetic conductive sheet to the inner liner in the prior art.

[0005] This application provides a liquid heating container, including: a kettle body, the kettle body includes an inner liner, a magnetic conductive sheet and a support member; the support member and the bottom wall of the inner liner jointly clamp the magnetic conductive sheet along the axial direction of the kettle body, so that the magnetic conductive sheet fits the outer surface of the bottom wall of the inner liner.

[0006] In the above solution, the support member can jointly limit the axial movement of the magnetic conductive sheet along the kettle body with the bottom wall of the inner liner, thereby improving the installation stability of the magnetic conductive sheet. Moreover, the support sheet can provide an upward supporting force to the magnetic conductive sheet to ensure that the magnetic conductive sheet is closely attached to the outer surface of the bottom wall of the inner liner, improve the fitting effect between the magnetic conductive sheet and the inner liner, and is beneficial to reducing the probability of local poor contact between the magnetic conductive sheet and the inner liner, thereby being beneficial to improving the heat transfer efficiency between the magnetic conductive sheet and the inner liner, and further being beneficial to improving the heating efficiency of the liquid heating container. Moreover, the magnetic conductive sheet and the inner liner in this embodiment are of a split structure, and the qualified rate during production is relatively high. During use, if the magnetic conductive sheet is damaged, it can also be replaced, which is beneficial to extending the service life of the liquid heating container.

[0007] In a possible design, the kettle body further includes a bottom cover and a compression spring; along the axial direction of the kettle body, one end of the compression spring abuts against the bottom cover, and the other end abuts against the surface of the support member away from the magnetic conductive sheet.

[0008] In the above solution, the compression spring can apply an upward axial pressure along the kettle body to the support member, driving the support member to axially squeeze the magnetic conductive sheet upward along the kettle body, thereby further improving the fitting effect between the magnetic conductive sheet and the bottom wall of the inner container. Installing the support member with a compression spring can avoid the problem of excessive local stress caused by rigid fixation, that is, it can ensure that the support member, the magnetic conductive sheet, and the bottom wall of the inner container can all be evenly stressed, reducing the risk of damage to the support member, the magnetic conductive sheet, and the bottom wall of the inner container, and also avoiding the problem that the magnetic conductive sheet warps due to excessive local stress and cannot fit with the bottom wall of the inner container.

[0009] In a possible design, one of the support member and the bottom cover is provided with a mounting post, and the other is provided with a spring sleeve; one end of the compression spring is sleeved on the mounting post, and the other end is installed in the spring sleeve.

[0010] In the above solution, the mounting post can limit one end of the compression spring to prevent the compression spring from displacing or deforming along the radial direction of the kettle body, and the spring sleeve can limit the other end of the compression spring, which can also prevent the compression spring from displacing or deforming along the radial direction of the kettle body. By setting the mounting post and the spring sleeve, the stability of the compression spring can be improved.

[0011] In a possible design, the support member is provided with a plurality of hollow portions, and the plurality of hollow portions are arranged at intervals along the circumferential direction of the support member.

[0012] In the above solution, the plurality of hollow portions are beneficial to reducing the weight of the support member and realizing the lightweight of the kettle body. The plurality of hollow portions are arranged at intervals along the circumferential direction of the support member to make the support member form a radially symmetric structure along the kettle body, so as to ensure that the support member can evenly fix the magnetic conductive sheet and avoid the phenomenon of eccentricity during the installation of the magnetic conductive sheet, thereby further improving the fitting effect between the magnetic conductive sheet and the bottom wall of the inner container.

[0013] In a possible design, the inner container has a receiving cavity. Along the axial direction of the kettle body, at least part of the bottom wall of the inner container is recessed towards the direction of the receiving cavity to form a mounting groove; the magnetic conductive sheet is installed in the mounting groove, and at least part of the support member extends into the mounting groove to jointly clamp the magnetic conductive sheet with the bottom wall of the mounting groove along the axial direction of the kettle body.

[0014] In the above scheme, when the magnetic sheet is installed in the installation groove, the side wall of the installation groove can limit the magnetic sheet and the support member along the axial direction of the kettle body, which can improve the installation stability of the magnetic sheet and the support member compared to the bottom wall of the inner liner with a planar structure. Moreover, since the installation groove is formed by the bottom wall of the inner liner being recessed toward the inside of the accommodating cavity, compared to the method of directly grooving the bottom wall of the inner liner, the thickness of the bottom wall of the inner liner can be kept consistent, ensuring that the structural strength of the bottom wall of the inner liner is not affected. Moreover, the consistent thickness of the bottom wall can also ensure the uniformity of the thermal conductivity of the inner liner, so that the liquid in the accommodating cavity can be heated evenly.

[0015] In a possible design, the magnetic conductive sheet includes a main body portion and a reinforcement portion that are fixedly connected, and the reinforcement portion is arranged circumferentially around the main body portion.

[0016] In the above solution, the reinforcement part can improve the structural strength of the magnetic conductive sheet and reduce the risk of deformation of the magnetic conductive sheet. Moreover, along the radial direction of the kettle body, the reinforcement part can cooperate with the side wall of the installation groove to achieve the effect of installation positioning, which is also conducive to further improving the installation stability of the magnetic conductive sheet and improving the fitting effect between the magnetic conductive sheet and the outer surface of the bottom wall of the inner container.

[0017] In a possible design, the thickness D1 of the magnetic conductive sheet is 0.3 mm to 1 mm.

[0018] In the above scheme, if the thickness D1 of the magnetic conductive sheet is too small (for example, less than 0.3 mm), the eddy current generated by the magnetic conductive sheet is too small, and the heat generated by the eddy current is too little, which will lead to too low heating efficiency of the liquid heating container; if the thickness D1 of the magnetic conductive sheet is too large (for example, greater than 1 mm), more materials are required for the magnetic conductive sheet, and the cost is higher, but the eddy current generated by it will not increase significantly. Therefore, when the thickness D1 of the magnetic conductive sheet is 0.3 mm to 1 mm, the heating efficiency of the liquid heating container can be improved, and the production cost of the liquid heating container can be appropriately reduced.

[0019] In a possible design, the kettle body further includes an outer shell, and along the axial direction of the kettle body, one end of the outer shell is fixedly connected to the inner liner, and the other end of the outer shell is fixedly connected to the bottom cover.

[0020] In the above scheme, the outer shell is used to fix the bottom cover and the inner pot to assemble the kettle body into a complete structure. The outer shell cooperates with the inner pot and the bottom cover to form a sealing structure to protect the components between the inner pot and the bottom cover from erosion by the external environment.

[0021] In a possible design, the liquid heating container also includes a base, which is used to support the pot body; the base is provided with an electromagnetic heating element, and the electromagnetic heating element is used to cooperate with the magnetic conductive sheet to heat the inner pot.

[0022] The electromagnetic heating element is used in cooperation with a magnetic conductive sheet to achieve electromagnetic heating: The electromagnetic heating element can generate an alternating magnetic field. When the kettle body is supported on the base, the magnetic conductive sheet is placed in this alternating magnetic field. The magnetic conductive sheet generates eddy currents due to the induced alternating magnetic field. Since the magnetic conductive sheet is attached to the outer surface of the bottom wall of the inner container, the heat generated by the eddy currents can heat the bottom wall of the inner container, thereby enabling the liquid in the accommodating cavity to be heated. Compared with the heating method using a heating disc, the heat loss of electromagnetic heating is smaller, which is beneficial to improving the heating efficiency of the liquid heating container.

[0023] In a possible design, the electromagnetic heating element is an electromagnetic coil with a disc-shaped structure.

[0024] In the above solution, the electromagnetic coil with a disc-shaped structure has a small volume and thickness, which is convenient for assembly, beneficial to reducing the occupied space of the base, and realizing the lightweight of the liquid heating container.

[0025] It should be understood that the above general description and the following detailed description are only exemplary and do not limit this application. Brief Description of the Drawings

[0059] To better understand the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0061] The terms used in the embodiments of the present application are for the purpose of describing specific embodiments only and are not intended to limit the present application. The singular forms "a", "the", and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms unless the context clearly dictates otherwise.

[0062] It should be understood that the term "and / or" used herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0063] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the perspective shown in the drawings and should not be construed as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0064] The embodiments of the present application provide a liquid heating container, such as Figure 1 and Figure 2 as shown, the liquid heating container includes a kettle body 1 and a base 2. The base 2 is used to support the kettle body 1, and the base 2 is provided with an electromagnetic heating element 21. The electromagnetic heating element 21 is used to cooperate with the magnetic conductive sheet 12 to achieve electromagnetic heating: the electromagnetic heating element 21 can generate an alternating magnetic field. When the kettle body 1 is supported on the base 2, the magnetic conductive sheet 12 is placed in the alternating magnetic field, and the magnetic conductive sheet 12 generates eddy currents due to the induced alternating magnetic field. Since the magnetic conductive sheet 12 is attached to the outer surface of the bottom wall of the inner container 11, the heat generated by the eddy currents can heat the bottom wall of the inner container 11, so that the liquid in the accommodating cavity 111 can be heated. Compared with the heating method of a heating disc, the heat loss of electromagnetic heating is smaller, which is beneficial to improving the heating efficiency of the liquid heating container.

[0065] The kettle body 1 includes an inner container 11, a magnetic conductive sheet 12, and a support member 13. The inner container 11 has a receiving cavity 111 for containing liquid. The support member 13 and the bottom wall of the inner container 11 jointly clamp the magnetic conductive sheet 12 along the axial direction Z of the kettle body 1, so that the magnetic conductive sheet 12 is attached to the outer surface of the bottom wall of the inner container 11. The support member 13 can jointly limit the movement of the magnetic conductive sheet 12 along the axial direction Z of the kettle body 1 with the bottom wall of the inner container 11, thereby improving the installation stability of the magnetic conductive sheet 12. Moreover, the support sheet 13 can provide an upward supporting force to the magnetic conductive sheet 12 to ensure that the magnetic conductive sheet 12 is closely attached to the outer surface of the bottom wall of the inner container 11, improving the fitting effect between the magnetic conductive sheet 12 and the inner container 11, which is beneficial to reducing the probability of local poor contact between the magnetic conductive sheet 12 and the inner container 11, thereby being beneficial to improving the heat transfer efficiency between the magnetic conductive sheet 12 and the inner container 11, and further being beneficial to improving the heating efficiency of the liquid heating container.

[0066] Electromagnetic heating is achieved by arranging the magnetic conductive sheet 12 at the bottom of the inner container 11 to cooperate with the electromagnetic heating element 21 in the base 2. Compared with the method of spraying a magnetic conductive coating on the bottom of the inner container 11, it can reduce the difficulty of the manufacturing process of the liquid heating container, improve the manufacturing efficiency of the liquid heating container, and also reduce the manufacturing cost of the liquid heating container. In addition, the qualified rate of the method of spraying a magnetic conductive coating on the bottom of the inner container 11 is relatively low. During the manufacturing process or use process, if the magnetic conductive coating is damaged, the inner container 11 cannot be used continuously. However, the magnetic conductive sheet 12 and the inner container 11 in this embodiment are of a split structure, and the qualified rate during manufacturing is relatively high. During the use process, if the magnetic conductive sheet 12 is damaged, it can also be replaced, which is beneficial to extending the service life of the liquid heating container.

[0067] Specifically, the outer surface of the bottom wall of the inner container 11 can be polished to ensure a better fitting effect between the magnetic conductive sheet 12 and the bottom wall of the inner container 11, thereby being beneficial to improving the heat transfer efficiency between the magnetic conductive sheet 12 and the inner container 11.

[0068] In this embodiment, the material of the inner container 11 can specifically be transparent glass or plastic, and this embodiment does not limit this. When the material of the inner container 11 is transparent glass, it is convenient for users to observe the liquid level and heating state of the liquid in the receiving cavity 111, and it is also more convenient for cleaning. The material of the magnetic conductive sheet 12 can specifically be carbon or 430 stainless steel, or other magnetic conductive materials, and this embodiment does not limit this.

[0069] In a specific implementation manner, the thickness D1 of the magnetic conductive sheet 12 is 0.3 mm to 1 mm. Specifically, D1 can be 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1 mm, or other values within the above range, and this embodiment does not limit this.

[0070] If the thickness D1 of the magnetic conductive sheet 12 is too small (for example, less than 0.3 mm), the eddy current generated by the magnetic conductive sheet 12 is too small, and the heat generated by the eddy current is too little, which will lead to too low heating efficiency of the liquid heating container; if the thickness D1 of the magnetic conductive sheet 12 is too large (for example, greater than 1 mm), more materials are required for the magnetic conductive sheet 12, and the cost is higher, but the eddy current generated by it will not increase significantly. Therefore, when the thickness D1 of the magnetic conductive sheet 12 is 0.3 mm to 1 mm, it can not only improve the heating efficiency of the liquid heating container, but also appropriately reduce the manufacturing cost of the liquid heating container.

[0071] As Figure 5 shown, the support member 13 is provided with a plurality of hollow portions 132. The plurality of hollow portions 132 are beneficial to reducing the weight of the support member 13 and realizing the light weight of the kettle body 1. The plurality of hollow portions 132 should be arranged at intervals along the circumferential direction of the support member 13 so that the support member 13 forms a radially symmetric structure along the kettle body 1 to ensure that the support member 13 can uniformly fix the magnetic conductive sheet 12 and avoid the phenomenon of eccentricity when the magnetic conductive sheet 12 is installed, thereby further improving the fitting effect between the magnetic conductive sheet 12 and the bottom wall of the inner liner 11.

[0072] The support member 13 can specifically be polyphenylene sulfide (PPS resin) or other high-temperature resistant non-magnetic conductive materials to prevent the support member 13 from melting under the high temperature of the magnetic conductive sheet 12. At the same time, the support member 13 cannot be a heat-conducting material to prevent the support member 13 from transferring the heat of the magnetic conductive sheet 12 to places outside the inner liner 11, thereby reducing heat loss, being beneficial to improving the heating efficiency of the liquid heating container, and also reducing the risk of melting of other components that are not resistant to high temperatures due to heat.

[0073] As Figure 4 shown, the kettle body 1 further includes a bottom cover 14 and a compression spring 15. Along the axial direction Z of the kettle body 1, one end of the compression spring 15 abuts against the bottom cover 14, and the other end abuts against the surface of the support member 13 away from the magnetic conductive sheet 12. The compression spring 15 is in a compressed state during installation, and it can apply an upward pressure along the axial direction Z of the kettle body 1 to the support member 13, driving the support member 13 to axially squeeze the magnetic conductive sheet 12 along the axial direction Z of the kettle body 1, thereby further improving the fitting effect between the magnetic conductive sheet 12 and the bottom wall of the inner liner 11. Even if the kettle body 1 shakes or tilts, the magnetic conductive sheet 12 can always be tightly attached to the bottom wall of the inner liner 11 under the action of the compression spring 15 and the support member 13.

[0074] Specifically, the number of compression springs 15 can be multiple. When multiple compression springs 15 uniformly apply pressure on the surface of the support member 13, it can play a role in uniformly fixing the support member 13. At the same time, the support member 13 can also uniformly squeeze the magnetic conductive sheet 12 upward, avoiding the phenomenon of eccentricity of the magnetic conductive sheet 12. Installing the support member 13 with compression springs 15 can avoid the problem of excessive local stress caused by rigid fixation, that is, it can ensure that the support member 13, the magnetic conductive sheet 12, and the bottom wall of the inner container 11 can all be evenly stressed, reducing the risk of damage to the support member 13, the magnetic conductive sheet 12, and the bottom wall of the inner container 11, and can also avoid the problem that the magnetic conductive sheet 12 warps due to excessive local stress and cannot fit with the bottom wall of the inner container 11.

[0075] Specifically, as Figures 4 to 6 shown, one of the support member 13 and the bottom cover 14 is provided with an installation post 131, and the other is provided with a spring sleeve 141. One end of the compression spring 15 is sleeved on the installation post 131, and the other end is installed in the spring sleeve 141.

[0076] The installation post 131 can limit one end of the compression spring 15 to prevent the compression spring 15 from displacing or deforming along the radial direction X of the kettle body 1. The spring sleeve 141 can limit the other end of the compression spring 15, and can also prevent the compression spring 15 from displacing or deforming along the radial direction X of the kettle body 1. By setting the installation post 131 and the spring sleeve 141, the stability of the compression spring 15 can be improved. Specifically, the positions and numbers of the installation post 131 and the spring sleeve 141 should correspond to the positions and numbers of the compression spring 15 to ensure that the compression spring 15 can be successfully installed in place.

[0077] As Figure 4 shown, the kettle body 1 further includes an outer shell 16. Along the axial direction Z of the kettle body 1, one end of the outer shell 16 is fixedly connected to the inner container 11, and the other end is fixedly connected to the bottom cover 14. The outer shell 16 is used to fixedly connect the bottom cover 14 and the inner container 11 to assemble the kettle body 1 into a complete structure. The outer shell 16 cooperates with the inner container 11 and the bottom cover 14 to form a sealed structure to protect the components between the inner container 11 and the bottom cover 14 from being eroded by the external environment.

[0078] Specifically, as Figure 7 shown, the outer shell 16 includes a fixedly connected bottom portion 161 and a side portion 162. The bottom wall and / or the side wall of the inner container 11 can be fixedly connected to the side portion 162 by gluing. The bottom portion 161 is a ring-shaped structure and is provided with a plurality of first mounting holes 161a spaced along the circumferential direction of the kettle body 1. As Figure 6As shown, the bottom cover 14 is provided with second mounting holes 142 corresponding to the plurality of first mounting holes 161a one by one. The kettle body 1 further includes a fastener, and the fastener sequentially passes through the first mounting holes 161a and the second mounting holes 142 along the circumferential direction Z of the kettle body 1 to realize the fixed connection between the outer shell 16 and the bottom cover 14.

[0079] In addition, as Figure 1 and Figure 2 shown, the kettle body 1 further includes a kettle lid 18 fastened to the top of the inner container 11 and a handle 17 mounted on the side wall of the inner container. The kettle lid 18 is used to prevent the liquid inside the inner container 11 from splashing, and the handle 17 facilitates the user to pick up and move the kettle body 1.

[0080] In this embodiment, the bottom wall of the inner container 11 can be a flat structure, and the magnetic conductive sheet 12 is closely attached to the outer surface of the bottom wall of the inner container 11 under the action of the support member 13, the bottom cover 14 and the compression spring 15. Alternatively, the bottom wall of the inner container 11 can be provided with a mounting groove 112 as Figure 2 shown. Along the axial direction Z of the kettle body 1, at least part of the bottom wall of the inner container 11 is recessed towards the accommodating cavity 111 to form the mounting groove 112. The magnetic conductive sheet 12 is installed in the mounting groove 112, and at least part of the support member 13 extends into the mounting groove 112 to jointly clamp the magnetic conductive sheet 12 with the bottom wall of the mounting groove 112 along the axial direction Z of the kettle body 1.

[0081] When the magnetic conductive sheet 12 is installed in the mounting groove 112, the side wall of the mounting groove 112 can also limit the magnetic conductive sheet 12 and the support member 13 along the axial direction X of the kettle body 1. Compared with the bottom wall of the inner container 11 with a flat structure, the installation stability of the magnetic conductive sheet 12 and the support member 13 can be improved. Moreover, since the mounting groove 112 is formed by recessing the bottom wall of the inner container 11 towards the inside of the accommodating cavity 111, compared with the way of directly grooving on the bottom wall of the inner container 11, the thickness of the bottom wall of the inner container 11 can be kept consistent, ensuring that the structural strength of the bottom wall of the inner container 11 is not affected. Moreover, the consistent thickness of the bottom wall can also ensure the heat conduction uniformity of the inner container 11, so that the liquid in the accommodating cavity 111 can be heated evenly.

[0082] In a specific embodiment, as Figure 3 shown, the magnetic conductive sheet 12 includes a main body portion 121 and a reinforcing portion 122 which are fixedly connected, and the reinforcing portion 122 is arranged around the circumferential direction of the main body portion 121.

[0083] The reinforcing portion 122 can improve the structural strength of the magnetic conductive sheet 12 and reduce the risk of deformation of the magnetic conductive sheet 12. Moreover, along the radial direction of the kettle body 1, the reinforcing portion 122 can be in limit fit with the side wall of the mounting groove 112, playing an effect of installation positioning, and is also beneficial to further improving the installation stability of the magnetic conductive sheet 12 and enhancing the fitting effect between the magnetic conductive sheet 12 and the outer surface of the bottom wall of the inner container 11.

[0084] In a specific embodiment, as Figure 8 shown, the electromagnetic heating element 21 is an electromagnetic coil in a disc shape, with a small volume and thickness, which is convenient for assembly, helps to reduce the occupied space of the base, and realizes the lightweight of the liquid heating container. The base 2 is provided with a receiving groove 22, and the receiving groove 22 extends along the axial direction Z of the kettle body 1. The kettle body 1 can be placed in the receiving groove 22, and the side wall of the receiving groove 22 can limit the kettle body 1 in the radial direction X of the kettle body 1 to improve the stability of the kettle body 1 during the working state and prevent it from tipping over easily.

[0085] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
