Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to an inner tank heating structure and a heating kettle body. Background Art

[0002] This section only provides background information related to the present application to help those skilled in the art understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] The bottom of the inner pot and the heat transfer plate in the existing heating kettle body are both flat plate structures, and the heat transfer plate is riveted with a nut column for connecting with the heat insulation bracket. In order to achieve higher heating power and reduce working noise, some merchants set the bottom of the inner pot and the heat transfer plate into a hemispherical structure to increase the heat conduction area between the two.

[0004] When the heat transfer plate is a hemispherical structure and the nut column is riveted on the spherical arc surface, the nut column will be arranged in an inclined shape, so it is difficult to connect with the heat insulation bracket; in addition, when the nut column is subjected to a large pulling force, the spherical arc surface of the heat transfer plate is prone to deformation, resulting in incomplete fit between it and the bottom of the pot, thereby reducing the heat conduction efficiency. In addition, since the temperature of the heat transfer plate is high, the temperature of the nut column riveted on the heat transfer plate is also high. When the nut column is directly connected to the heat insulation bracket, the heat on the nut column can be transferred to the heat insulation bracket to increase the temperature of the heat insulation bracket, thereby causing the outer shell temperature of the heating kettle to be high, affecting the user experience.

[0040] Embodiment 1

[0041] See also Figure 1-4 The utility model provides an inner tank heating structure 1, comprising an inner tank 11, a heating component and a heat insulating bracket 14, wherein the inner tank 11 comprises a tank body 111 and a tank bottom 112, wherein the tank body 111 is a cylindrical structure, and the tank bottom 112 is a hemispherical structure with a bottom plane, and the bottom edge of the tank body 111 and the top edge of the tank bottom 112 are welded and fixed up and down to form the inner tank 11; the heating component comprises a heat transfer plate 12 and a heating element arranged on the lower end surface of the heat transfer plate 12, wherein the heat transfer plate 12 is adapted to the shape of the tank bottom 112 (i.e., the hemispherical structure with a bottom plane), and it is attached to the bottom of the tank bottom 112 to achieve heat conduction; preferably, the heating element is a heating pipe 13; the heat insulating bracket 14 is connected to the heat transfer plate 12 and is located below the heat transfer plate 12.

[0042] The edge of the heat transfer plate 12 is bent outward to form a flange 121 . The flange 121 is arranged horizontally and is provided with a connector 15 for connecting to the heat insulation bracket 14 . A heat insulation member is provided at the connection between the heat insulation bracket 14 and the connector 15 .

[0043] Since the heat transfer plate 12 is a hemispherical structure, the edge of the heat transfer plate 12 is turned outward to form a flange 121 and the connector 15 is riveted to the flange 121, so that the connector 15 can be arranged vertically, thereby facilitating its connection with the heat insulation bracket 14; in addition, when the connector 15 is subjected to a large pulling force, only the flange 121 will be deformed, while the spherical arc surface on the heat transfer plate 12 can still be completely fitted with the bottom 112 of the bladder, thereby ensuring the fit between the two, thereby ensuring the heat conduction efficiency.

[0044] Secondly, by providing a heat insulating member, contact between the connecting member 15 and the heat insulating bracket 14 is avoided, thereby preventing or greatly reducing heat conduction to the heat insulating bracket 14, thereby avoiding an increase in the temperature of the heat insulating bracket 14; in addition, since the heat insulating bracket 14 is provided, the heat radiation generated by the heating element can be blocked to a large extent, so that the temperature of the outer shell 2 of the heating kettle body will not be too high, thereby improving the user experience.

[0045] In this embodiment, the bladder body 111 and the bladder bottom are both made of stainless steel.

[0046] See also Figure 4 Preferably, the heat insulating member is a heat insulating pad 16, which is inserted into the heat insulating bracket 14; specifically, the heat insulating pad 16 includes a body portion 161 and a boss portion 162 disposed on the body portion 161, and the heat insulating bracket 14 is provided with a plurality of positioning bosses 141, and the positioning bosses 141 are provided with a second through hole 1411 in a stepped shape, and the body portion 161 passes through the second through hole 1411 and abuts against the step surface through the boss portion 162 to achieve limited abutment. Among them, a first through hole 163 in a stepped shape is provided in the heat insulating pad 16.

[0047] Furthermore, the connecting member 15 is a nut column riveted on the flange 121, which extends from one end of the first through hole 163 and abuts against the step surface; in addition, it also includes a first locking bolt 17, which extends from the other end of the first through hole 163 and is threadedly connected to the nut column, thereby realizing the connection and fixation between the heat transfer plate 12 and the insulation bracket 14.

[0048] Therefore, the nut column and the first locking bolt 17 are connected to the insulation bracket 14 through the insulation pad 16, thereby effectively preventing or reducing the heat on the nut column or the first locking bolt 17 from being transferred to the insulation bracket 14, avoiding the temperature of the insulation bracket 14 to increase.

[0049] Preferably, the thermal insulation pad 16 is made of PET material.

[0050] Preferably, the thermal insulation bracket 14 is made of PP plastic material, which has a certain deformation ability; when the inner tank heating structure 1 falls or is subjected to a large force, the thermal insulation bracket 14 can produce a certain deformation to achieve a buffering effect, thereby protecting the components and extending their service life.

[0051] See also Figure 1-4 In order to further improve the support strength of the flange 121, a plurality of grooves are integrally stamped on the flange 121 to form a recessed portion 123, and the nut column is riveted on the recessed portion 123 to improve the support strength of the nut column. At the same time, since the temperature of the heat transfer plate 12 is relatively high, in order to reduce the temperature of the heat transfer plate 12 being transferred to the nut column, a plurality of long strip-shaped through grooves 122 are provided on the heat transfer plate 12 near the flange 121. The plurality of through grooves 122 are arranged at intervals along the circumferential direction and correspond to the plurality of recessed portions 123 one by one. The through grooves 122 can block the heat transferred from the heat transfer plate 12 to the flange 121, thereby reducing the temperature of the nut column, thereby reducing the heat transferred from the nut column to the heat insulation bracket 14.
