[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] See also Figure 1-6 The utility model provides a low-noise heating kettle body, including an inner pot 1, a heat transfer plate 2 arranged at the bottom of the inner pot 1, and a heating tube arranged on the lower end surface of the heat transfer plate 2. Specifically, the inner pot 1 includes a pot body 11 and a pot bottom 12 arranged at the bottom of the pot body 11. The pot body 11 is a cylindrical structure, and the pot bottom 12 is a hemispherical structure with a bottom plane. The bottom edge of the pot body 11 and the top edge of the pot bottom 12 are welded and fixed up and down to form the inner pot 1. The heat transfer plate 2 is adapted to the shape of the gallbladder bottom 12 (i.e., the hemispherical structure of the bottom plane), and the heat transfer plate 2 is sleeved on the bottom of the gallbladder bottom 12 and is completely fitted with the bottom surface of the gallbladder bottom 12; the heating tube includes a first heating tube 3 and a second heating tube 4, the first heating tube 3 and the second heating tube 4 are both arc-shaped structures and the diameter of the first heating tube 3 is smaller than that of the second heating tube 4, and the first heating tube 3 and the second heating tube 4 are arranged in sequence from the inside to the outside; wherein, the upper end surfaces of the first heating tube 3 and the second heating tube 4 are both provided with arc surfaces, and are completely fitted with the lower end surface of the heat transfer plate 2 through the arc surfaces.

[0038] Therefore, under the action of the first heating tube 3 and the second heating tube 4, the heat transfer plate 2 can be heated, and then the heat is transferred to the inner pot 1 through the heat transfer plate 2 to heat the water in the inner pot 1.

[0039] Therefore, by setting the bottom 12 and the heat transfer plate 2 to a hemispherical structure and fitting them together, the heat conduction area is increased and the heat conduction efficiency is improved compared with the traditional flat plate structure of the heat transfer plate 2; at the same time, the first heating tube 3 and the second heating tube 4 are both provided with curved surfaces and fit closely with the heat transfer plate 2, so that the heating area is larger and the heat is evenly distributed, thereby achieving higher heating power and lower working noise, greatly improving the user experience.

[0040] Preferably, the bottom 12 and the heat transfer plate 2 are stamped and formed by the same molding die, so as to ensure the adaptability of the shapes of the two to the greatest extent, and further ensure the flatness of the fit between the two.

[0041] Furthermore, a positioning structure is provided between the gallbladder bottom 12 and the heat transfer plate 2, and the positioning structure includes a positioning column 121 and a positioning hole 22 that are mutually engaged, the positioning column 121 is provided on the bottom surface of the gallbladder bottom 12, and the positioning hole 22 is provided on the heat transfer plate 2. Thus, by providing the positioning structure, when the gallbladder bottom 12 and the heat transfer plate 2 are stamped together and separated, and then the two are welded together, the positioning structure can realize accurate positioning of the two, thereby ensuring the flatness of the fitting between the two.

[0042] Of course, in other embodiments, the positioning structure can also be a positioning column 121 and a positioning groove that are interlocked. The positioning column 121 is set on the upper end surface of the heat transfer plate 2, and the positioning groove is opened on the bottom surface of the bottom 12 of the tank. It can also achieve the same technical effect, which is not limited here.

[0043] See also Figure 1-4 , and also includes a fixing bracket 5 arranged under the heat transfer plate 2. The edge of the heat transfer plate 2 is bent outward to form a flange 21.

The heat transfer plate 2 is connected and fixed to the fixing bracket 5 through the plurality of nut columns 23.

[0044] Therefore, by arranging the nut column 23 on the flange 21 instead of the heat transfer plate 2, it is possible to avoid deformation of the spherical surface of the heat transfer plate 2 due to force pulling, thereby ensuring the flatness of the fit between the heat transfer plate 2 and the bottom 12 of the pan; at the same time, in order to further improve the supporting strength of the flange 21, a plurality of grooves are integrally stamped on the flange 21 to form a recessed portion 24, and the nut column 23 is inserted into the recessed portion 24 to improve the supporting strength of the nut column 23.

[0045] At the same time, since the temperature of the heat transfer plate 2 is relatively high, in order to prevent the temperature of the heat transfer plate 2 from being transferred to the nut column 23 and then to the fixing bracket 5, a plurality of long strip-shaped through grooves 25 are further provided on the heat transfer plate 2 near the flange 21. The plurality of through grooves 25 are arranged at intervals along the circumferential direction and correspond one to one with the plurality of recessed portions 24. The through grooves 25 can block the heat transferred from the heat transfer plate 2 to the flange 21, thereby reducing the temperature of the nut column 23, thereby reducing the heat transferred from the nut column 23 to the fixing bracket 5.

[0046] Furthermore, the fixing bracket 5 is also provided with a boss 51 corresponding to a plurality of nut columns 23, the boss 51 is penetrated by a heat insulating pad 52, and the heat insulating pad 52 is provided with a positioning groove; when the heat transfer plate 2 needs to be connected to the fixing bracket 5, the nut column 23 can be inserted into the positioning groove, and then a locking bolt is inserted from the other side of the positioning groove and threadedly connected with the nut column 23 to realize the connection between the heat transfer plate 2 and the fixing bracket 5.

[0047] Furthermore, the heating kettle body also includes a shell 6, and a receiving cavity 61 is provided inside the shell 6, and the inner pot 1, the heat transfer plate 2, the heating pipe and the fixing bracket 5 are all arranged in the receiving cavity 61. The fixing bracket 5 is provided with a plurality of positioning slots 53, and the bottom of the receiving cavity 61 is provided with a positioning column 62 that matches with the plurality of positioning slots 53; the positioning slots 53 are provided with through holes, and the positioning column 62 is provided with screw holes. When the fixing bracket 5 needs to be fixed to the receiving cavity 61, the positioning column 62 can be inserted into the positioning slot 53, and then a locking screw is passed through the through hole and threadedly connected to the screw hole to realize the assembly of the fixing bracket 5 and the receiving cavity 61.

[0048] In addition, the utility model also provides a heating device, comprising a base (not shown in the figure) and a low-noise heating kettle detachably placed on the base.

[0049] In summary, the low-noise heating kettle body and heating device provided by the utility model have the following beneficial effects:

[0050] (i) The low-noise heating kettle body of the utility model has a bottom 12 and a heat transfer plate 2 which are both arranged in a hemispherical structure and fit each other, thereby increasing the heat conduction area and improving the heat conduction efficiency; at the same time, the heating tube is provided with an arc surface which fits closely with the heat transfer plate 2, so that the heating area is larger and the heating is uniform, thereby achieving higher heating power and lower working noise, greatly improving the user experience.
