Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of household appliances, specifically relates to a heating container beneficial to bottom heat dissipation. BACKGROUND

[0002] In the field of existing electric heating equipment, heating components (such as heating pipes, heating discs) are widely used in various heating containers, such as electric rice cookers, electric kettles, coffee machines and electric food warmers, etc. The basic working principle of these devices is to generate heat through the heating component, and then transfer the heat to the liquid or solid food in the container to achieve the purpose of heating, cooking or heat preservation. For example, in the prior art, the Chinese patent with publication number CN202589275U discloses a heat preservation intelligent electric kettle, which is provided with an annular heating pipe at the bottom of the inner container. The heat energy generated by the heating pipe can be maximally received by the inner container, and the thermal efficiency is extremely high.

[0003] However, the conventional heating component design generally faces a technical problem, i.e. the effective dissipation of heat. Specifically, when the conventional heating component is working, a large amount of heat will be generated inside due to the conversion of electrical energy into heat energy. If this heat cannot be effectively dissipated in time, it will continue to accumulate inside the device. Especially in the case of long-time operation, the accumulation of heat will cause the temperature inside the device to continuously rise, showing a linear growth trend. This temperature rise not only affects the working efficiency of the heating component and reduces its service life, but also may cause safety hazards, such as the risk of fire caused by overheating. The above-mentioned prior art is mainly used for preventing dry burning, and does not mention how to solve the problem of heat dissipation.

[0004] Therefore, there is an urgent need for a heating container beneficial to bottom heat dissipation. SUMMARY

[0005] In view of the problems in the related art, the utility model provides a heating container beneficial to bottom heat dissipation to overcome the above technical problems existing in the prior art. By setting the first heat dissipation structure, the second heat dissipation structure and the third heat dissipation structure, the heat generated by the heating unit when working can be dissipated through two independent but cooperative paths, ensuring the rapid dissipation of heat and preventing overheating of the container body and the heat dissipation base. This design not only improves the heat dissipation efficiency, but also ensures the uniform distribution and rapid conduction of heat.

[0023] Furthermore, the contact between each of the support feet and the top surface of the power supply base can be point-like, line-like, or surface-like;

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] like Figures 1-10 As shown, this embodiment provides a heating container that facilitates heat dissipation from the bottom, including a container body 1 and a heat dissipation base 2 connected to each other. The heat dissipation base 2 includes a base shell 21 and an isolation cover 22 disposed inside the base shell 21. The isolation cover 22 divides the inner cavity of the base shell 21 into an adjacent heating cavity 24 and an isolation cavity 25.

[0052] The lower end of the container body 1 extends into the heating chamber 24; a heating unit 3 is provided on the outer bottom surface of the container body 1, which is used to heat the liquid in the container body 1; the isolation cover 22 is located below the heating unit 3.

[0053] The isolation cavity 25 is provided with a first coupling part 9, which is exposed on the lower end face of the isolation cavity 25; it also includes a power supply base 4, the upper part of which is provided with a second coupling part. When the container body 1 and the heat dissipation base 2 are placed on the power supply base 4, the first coupling part 9 is coupled to the second coupling part.

[0054] A heat dissipation gap 5 is provided between the bottom surface of the base shell 21 and the top surface of the power supply base 4, and the heat dissipation gap 5 is in communication with the outside air; a first heat dissipation structure 6 is provided with a downward protrusion on the bottom surface of the isolation cover 22, the first heat dissipation structure 6 extends and passes through the isolation cavity 25, and is connected to the bottom surface of the base shell 21, and the first heat dissipation structure 6 connects the heating cavity 24 with the heat dissipation gap 5.

[0055] Firstly, this embodiment achieves efficient heat conduction and dissipation by setting up a heat dissipation base 2 and a container body 1. In particular, the first heat dissipation structure 6 ensures rapid heat dissipation by dissipating the heat generated by the heating unit 3 during operation, preventing overheating of the container body 1 and the heat dissipation base 2. This design not only improves heat dissipation efficiency but also ensures uniform heat distribution and rapid conduction.

[0056] Furthermore, this embodiment combines the container body 1 with the heat dissipation base 2, improving the overall structural compactness. The first heat dissipation structure 6 effectively conducts and dissipates heat without adding extra volume, reflecting the design concept of a compact structure.

[0057] Specifically, a second heat dissipation structure is provided on the bottom surface of the isolation cover 22 around the port of the first heat dissipation structure 6, and the second heat dissipation structure connects the heating cavity 24 and the isolation cavity 25; a third heat dissipation structure is provided on the bottom surface of the base shell 21, and the third heat dissipation structure connects the isolation cavity 25 and the heat dissipation gap 5.

[0058] In this embodiment, the heat generated by the heating unit 3 during operation is dissipated through the following two paths: a portion of the heat is directly conducted through the first heat dissipation structure 6 to the heat dissipation gap 5, and then the heat dissipation gap 5 is transferred to the outside air, forming the first path; another portion of the heat is first conducted through the second heat dissipation structure to the isolation cavity 25, and then through the third heat dissipation structure to the heat dissipation gap 5, and finally the heat dissipation gap 5 is transferred to the outside air, forming the second path.

[0059] This embodiment, by setting up a first heat dissipation structure 6, a second heat dissipation structure, and a third heat dissipation structure, allows the heat generated by the heating unit 3 during operation to be dissipated through two independent but coordinated paths, ensuring rapid heat dissipation and preventing overheating of the container body 1 and the heat dissipation base 2. This design not only improves heat dissipation efficiency but also further ensures uniform heat distribution and rapid conduction.

[0060] Specifically, the first heat dissipation structure 6 includes a first heat dissipation channel 61 disposed on the isolation cover 22 and a second heat dissipation channel 62 disposed on the base housing 21;

[0061] The first heat dissipation channel 61 extends downward from the bottom surface of the isolation cover 22 into the second heat dissipation channel 62, and the first heat dissipation channel 61 and the second heat dissipation channel 62 are connected; the diameter of the first heat dissipation channel 61 is smaller than the diameter of the second heat dissipation channel 62.

[0062] like Figure 7 As shown, the first heat dissipation channel 61 and the second heat dissipation channel 62 are separately configured;

[0063] It should be noted that when the heat sink base 2 is provided with a buffer structure and the first heat sink channel 61 and the second heat sink channel 62 are separately configured, the first heat sink channel 61 can move up and down along the axial direction within the second heat sink channel 62, wherein the second heat sink channel 62 provides sufficient buffer space for the first heat sink channel 61.

[0064] Alternatively, the first heat dissipation channel 61 and the second heat dissipation channel 62 may be integrally formed.

[0065] It should be further explained that when the first heat dissipation channel 61 and the second heat dissipation channel 62 are integrally formed, the heat dissipation channels of the first heat dissipation structure 6 are more concentrated and the heat dissipation efficiency is more efficient.

[0066] Specifically, the bottom center of the base housing 21 is recessed inward to form a first slope 211; the second heat dissipation channel 62 extends upward from the first slope 211 to connect with the first heat dissipation channel 61.

[0067] It should be noted that this embodiment designs a first heat dissipation channel 61 and a second heat dissipation channel 62. The first heat dissipation channel 61 is located on the isolation cover 22, extending downwards from the bottom surface of the isolation cover 22, while the second heat dissipation channel 62 is located on the base shell 21, extending upwards from the first slope 211 formed by the inward indentation at the center of the bottom surface of the base shell 21 to connect with the first heat dissipation channel 61. This design not only ensures smooth heat conduction but also further enhances the heat dissipation effect through the change in channel diameter. Specifically, when the heating unit 3 is working, the generated heat is first conducted to the first heat dissipation channel 61 through the isolation cover 22. Due to the small diameter of the first heat dissipation channel 61, the heat is initially concentrated and the conduction is accelerated at this point. Subsequently, the heat enters the second heat dissipation channel 62 through the connection between the first heat dissipation channel 61 and the second heat dissipation channel 62. Due to the larger diameter of the second heat dissipation channel 62, the heat can be further diffused and dissipated into the heat dissipation gap 5 at this point.

[0068] Specifically, the third heat dissipation structure is disposed on the first slope 211; the third heat dissipation structure includes a plurality of first heat dissipation holes 7; the plurality of first heat dissipation holes 7 are evenly distributed in multiple directions with the second heat dissipation channel 62 as the starting point;

[0069] More specifically, the shape of the first heat dissipation hole 7 includes a circle, a polygon, and an irregular shape; wherein, the irregular shape includes an ellipse, an arc, and a wave shape;

[0070] Specifically, the base shell 21 includes a side shell wall 215, the bottom end of which is connected to the bottom end of the first slope 211 through a transition plane 212. The transition plane 212 is provided with a plurality of irregular grooves 2121, the shape of which includes arc or circle. Each irregular groove 2121 has a through hole 2122 for heat dissipation on its side wall.

[0071] In this embodiment, first heat dissipation holes 7 are provided on the first slope 211 of the base shell 21, which are evenly distributed in multiple directions, increasing the heat dissipation area and further enhancing the uniform distribution of the first heat dissipation holes 7. Moreover, the provision of the irregular groove 2121 and through hole 2122 further increases the heat dissipation path, achieving effective heat dispersion and dissipation, and avoiding overheating caused by local heat accumulation in the isolation cavity 25.

[0072] Specifically, the bottom of the transition plane 212 is provided with a plurality of support feet 214; when the container body 1 and the heat dissipation base 2 are placed on the power supply base 4, each of the support feet 214 is in contact with the top surface of the power supply base 4, and at this time the space between the bottom surface of the base shell 21 and the top surface of the power supply base 4 forms the heat dissipation gap 5.

[0073] The heat dissipation gap 5 is designed to allow heat to be smoothly transferred to the outside air;

[0074] More specifically, the contact between each of the support feet 214 and the top surface of the power supply base 4 includes point-like, line-like, or surface-like contact.

[0075] It should be noted that the bottom of the transition plane 212 is provided with three support feet 214; in this embodiment, the bottom of the transition plane 212 is provided with eight support feet 214 evenly.

[0076] Specifically, the second heat dissipation structure includes a plurality of second heat dissipation holes 8; the plurality of second heat dissipation holes 8 are arranged in a circular array with the port of the first heat dissipation structure 6 as the center, so as to achieve 360° full coverage;

[0077] More specifically, each column is provided with at least two second heat dissipation holes 8; the shape of the second heat dissipation holes 8 includes circular, polygonal, and irregular shapes; wherein, the irregular shapes include elliptical, arc, and wavy shapes;

[0078] This embodiment provides multiple second heat dissipation holes 8 arranged in a circumferential array, which further increases the heat dissipation area. The uniform and radiating arrangement of the second heat dissipation holes 8 also enables the effective dispersion and dissipation of heat within the heating cavity 24, avoiding overheating caused by localized heat accumulation within the heating cavity 24.

[0079] Specifically, the container body 1 includes an integrally formed upper container body 11 and a lower container body 12. The bottom end of the upper container body 11 narrows horizontally inward and connects with the top end of the lower container body 12. The diameter of the upper container body 11 is larger than the diameter of the lower container body 12. The lower container body 12 extends into the inner cavity of the heat dissipation base 2.

[0080] The isolation cover 22 has a raised, annular side wall 221. The top of the side wall 221 is connected to a support ring frame 23, which is used to support the lower container body 12. The heating unit 3 is provided on the outer bottom surface of the lower container body 12. The bottom of the lower container body 12, the support ring frame 23, and the isolation cover 22 together form the heating cavity 24. The bottom of the isolation cover 22 and the base shell 21 together form the isolation cavity 25.

[0081] Specifically, the heat dissipation base 2 is provided with a first coupling part 9 at the bottom center of the base housing 21;

[0082] In this embodiment, the arrangement of the first coupling part 9 and the second coupling part enables the bottom of the heating container to be indirectly electrically connected to the power supply base 4.

[0083] Specifically, the upper end of the support ring 23 narrows horizontally inward to form a narrow opening 231 for abutting against the side wall of the lower container body 12;

[0084] Specifically, the heating unit 3 includes a heating tube 31 and a heat-conducting plate 32. The bottom of the heat-conducting plate 32 is provided with a support column 33 protruding downwards. The lower end of the support column 33 extends into the transition member 34 and is connected to the isolation cover 22 through the transition member 34.

[0085] The supporting ring 23, narrow opening 231, transition piece 34, etc., are mainly used to fix the lower container body 12 and the heating unit 3. This not only makes the internal structure of the heat dissipation base 2 more compact, but also ensures that there is sufficient space for heat dissipation between the heating unit 3 and the isolation cover 22, so as to ensure that the heating unit 3 and the isolation cover 22 remain in a non-contact state, thereby enhancing the durability and service life of the isolation cover 22 and even the entire heating container. At the same time, it further expands the heat dissipation space of the heating cavity 24, so that heat can flow and diffuse in the heating cavity 24, and finally be effectively dissipated through the first path and the second path.

[0086] More specifically, the bottom of the lower container 12 is provided with an arc-shaped bottom surface 121, and the vertical cross-section of the heat conduction plate 32 is arc-shaped. Compared with the traditional planar design, the arc-shaped design is conducive to increasing the heat conduction area of ​​the bottom surface of the lower container 12 and the heat conduction plate 32, resulting in a higher heat conduction rate.

[0087] Specifically, a sealing sleeve 10 is provided at the interface between the base shell 21 and the container body 1 to enhance the sealing of the inner cavity of the heat dissipation base 2 and prevent moisture, impurities and other substances in the outside air from entering.

[0088] In this embodiment, the heating cavity 24 formed by the bottom of the lower container 12, the support ring 23, and the isolation cover 22 provides a stable heat source environment for liquid heating. This design not only improves heating efficiency but also ensures heating uniformity, avoiding problems such as local overheating or underheating.

[0089] Furthermore, this embodiment combines the container body 1 with the heat dissipation base 2. Through the design of the integrally formed upper container body 11 and lower container body 12, and the layout of the lower container body 12 extending into the inner cavity of the heat dissipation base 2, the overall structural compactness is significantly improved. At the same time, the connection design between the protruding annular side wall 221 of the isolation cover 22 and the support ring frame 23 not only enhances the stability of the structure, but also cleverly utilizes space, allowing the heating cavity 24 and the isolation cavity 25 to be arranged compactly.

[0090] Furthermore, the arrangement of the first, second, and third heat dissipation structures effectively conducts and dissipates heat without adding extra volume, further demonstrating the compact design concept. This highly integrated structural design not only reduces the overall size of the device but also improves heat dissipation efficiency.

[0091] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
