Abstract
The utility model relates to an improved structure of an electrical heating unit for a vacuum thermos bottle, which is characterized by comprising vacuum interlayer lateral wall with depressed parts, and a bottom which is higher than the vacuum interlayer lateral wall with depressed parts and provided with a heating panel. Circular rings are arranged below the circumference of the bottom. The bottom is connected with the depressed parts of the vacuum interlayer lateral wall by lower circular rings of the circular rings. The heating panel is a cast aluminium electric hot plate. The upper surface of the heating panel is convex. The bottom is a spherical surface matched with the upper surface of the heating panel. A gap between a side face of the heating panel and the circular rings is 0.05-1.00mm. Compared with the prior art, the utility model has the advantage that the side face of the electric hot plate can be fully and closely connected with the vacuum interlayer lateral wall.
Description
Technical field:
The utility model relates to a kind of household electrical appliance heating element structure.
Background technology:
Existing thermos mainly contains two kinds with electric heating element structure, and a kind of is that electric heating body is arranged in the thermos, and a kind of is that electric heating body is arranged on outside the thermos.The advantage that electric heating body is arranged in the thermos is that electric heating body can fully contact with water, and heat exchanger effectiveness is the highest, and shortcoming is that easy outer surface at electric heating body forms incrustation scale, thereby seriously influences the water quality of the heat transfer efficiency and the drinking water of electric heating body.Electric heating body is arranged on outside the thermos, though overcome the shortcoming of structure in first,,, make the heat transfer efficiency of heater be subjected to very big influence because existing technology has only been utilized the wherein one side of heater.For this reason, the inventor has invented the technology of patent application 200920051525.2, this technology is the aluminium alloy plate of side flanging outside being provided with below electric boiling plate, like this, the thermal expansion by when heating swells outer side flanging and leans against the heating surface area that increases the hot water water in bottle on the in-flanges of vacuum interlayer sidewall.This technology is owing to have only the in-flanges of electric boiling plate side to lean against on the vacuum interlayer sidewall, and other position of electric boiling plate side does not contact with the vacuum interlayer sidewall, makes the vacuum interlayer sidewall fully not obtain heat energy from electric boiling plate.
Summary of the invention:
The vacuum thermos that provides a kind of electric boiling plate side fully to abut against with the vacuum interlayer sidewall improvement structure of electric heating body is provided goal of the invention of the present invention.
The utility model is to realize like this, the end that has heating plate of the in-flanges that comprise the vacuum interlayer sidewall that has in-flanges, exceeds the vacuum interlayer sidewall, it below the bottom perimeter annulus, the end, link together by the following annulus of annulus and the in-flanges of vacuum interlayer sidewall, heating plate is a cast aluminium electrothemic plate, the heating plate upper surface is an epirelief sphere, and the end is a sphere that matches with the heating plate upper surface, and the gap between heating plate side and annulus is 0.05-1.00mm.During heating, heating plate expands, and its lateral parts closely contacts because of expansion with the bottom periphery annulus, thereby has increased the heat transfer area of heating plate.Container body neighboring, bottom (inner rim contacts with the alloy aluminium sheet) is exposed and is contacted with heating liquid, so, can reach heating board top and periphery together to the purpose of liquid heat, heat efficiency utilization is higher, heat-transfer effect is significantly improved than common heating mode, and near the temperature rise ratio common heating structure making bottom the heating board obviously reduces, and near electronic component and the wiring board that is contained in the bottom had very big benefit.The heating plate upper surface adopts sphere, and heating plate expands, and its lateral parts and bottom periphery annulus make the bottom periphery annulus produce an outside pulling force because of expansion closely contacts, and like this, under the effect of pulling force, the end just more is close on the sphere heating plate.Adopting the gap between heating plate side and annulus is 0.05-1mm, in the time of can making heating, the heating plate lateral parts closely contacts because of expansion with the bottom periphery annulus, simultaneously, again can be not excessive because of expansive force, cause the end to produce inelastic deformation, the internal diameter of bottom periphery annulus is enlarged, finally after the internal diameter of constantly accumulation enlarges, cause the heating plate lateral parts after thermal expansion, all can not closely contact, influenced heat-transfer effect with the bottom periphery annulus.
Compared with the prior art the utility model has the advantage that the electric boiling plate side can fully abut against with the vacuum interlayer sidewall.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the present invention includes the vacuum interlayer sidewall 2 that has in-flanges 1, exceed the end that has heating plate 34 of the in-flanges 1 of vacuum interlayer sidewall 2, be annulus 5 below the ends 4 periphery, the end 4, link together by the following annulus 5a of annulus 5 and the in-flanges 1 of vacuum interlayer sidewall 2, heating plate 3 is cast aluminium electrothemic plates, heating plate 3 upper surface 3a are epirelief spheres, the end 4 is spheres that match with heating plate 3 upper surface 3a, 3b is perforation in the middle of the heating plate 3, present convex at the end 4 of corresponding perforation, so that the installing Temperature Detector, the gap B that heating plate 3 side 3c and annulus are 5 is 0.05-1.00mm.The gap B that heating plate 3 side 3c and annulus are 5 is to be best between 0.05-0.50mm.
Claims (3)
1. a vacuum thermos is with the improvement structure of electric heating body, the end that has heating plate of the in-flanges that it is characterized in that comprising the vacuum interlayer sidewall that has in-flanges, exceeds the vacuum interlayer sidewall, it below the bottom perimeter annulus, the end, link together by the following annulus of annulus and the in-flanges of vacuum interlayer sidewall, heating plate is a cast aluminium electrothemic plate, and the gap between heating plate side and annulus is 0.05-1.00mm.
2. vacuum thermos according to claim 1 is characterized in that with the improvement structure of electric heating body the gap between heating plate side and annulus is between 0.05-0.50mm.
3. vacuum thermos according to claim 1 is characterized in that with the improvement structure of electric heating body the heating plate upper surface is an epirelief sphere, and the end is a sphere that matches with the heating plate upper surface.
