Electrothermal stainless steel kettle teapot
The utility model relates to the small household appliances field, particularly relates to the electrothermal kettle teapot.
At present, the common use of electrothermal stainless steel kettle, but electric heater all is arranged on the position in the water in the kettle, and electric heater damages the back and is difficult for repairing, and not easy to clean clean after dirty, and water quality is impacted.Therefore, very need a kind of electric heater be arranged on kettle and hold outside the water section, have good heat transfer efficiency and the convenient new-type electrothermal stainless steel kettle teapot that kettle is keeped in repair.
The purpose of this utility model is to provide a kind of electrothermal stainless steel kettle teapot of new construction, and its heater is not placed in the water, and is placed on and the direct mutually position contacting of water, has good heat transfer efficiency, and conveniently kettle is keeped in repair.
The purpose of this utility model is achieved in that promptly provides a kind of electrothermal stainless steel kettle teapot, by at the bottom of kettle body, the kettle and electric heater constitute, electric heater be arranged at the bottom of the kettle below, and contact at the bottom of the kettle, electric heater is connected with at the bottom of the kettle in the brazing mode.
Kettle teapot of the present utility model is simple in structure, lays rationally, and assembling and maintenance are easily.Because electric heater not with kettle in water directly contact, so can ensure the cleaning of water in the kettle; Electric heater can adopt bigger power.The brazing connection has good heat transfer efficient.
Describe embodiment of the present utility model with reference to the accompanying drawings in detail.Wherein
Fig. 1 is the structure diagram of the utility model kettle teapot;
Fig. 2 turns schematic perspective view when seeing with the kettle teapot among Fig. 1;
Fig. 3 is along the cutaway view of A-A among Fig. 2.
Consult Fig. 1, it is the cutaway view of the primary structure of the utility model kettle teapot.Wherein, kettle teapot is by kettle body 1, at the bottom of the kettle 2 and electric heater 3 constitute.Electric heater 3 be not arranged at the bottom of the kettle 2 above, and be arranged at the bottom of the kettle 2 below, and contact with at the bottom of the kettle, and with the brazing mode with 2 be connected at the bottom of the kettle.Because when using electric heater, the transmission of heat mainly by conduction pattern, therefore, is connected electric heater 3 in the brazing mode with at the bottom of the kettle, just having guaranteed has fabulous heat transfer efficiency, also convenient maintenance to electric heater 3.
As shown in Figure 1, electric heater 3 is provided with the neighboring of 2 baseplane at the bottom of the kettle.
2 periphery has adopted the ridge structure of convex-concave bending at the bottom of the kettle, and this structure increases the intensity of kettle teapot and non-deformability greatly.In addition, as can be seen, 2 modes with flanging are connected with kettle body 1 at the bottom of the kettle, and this flanging connected mode is convenient for maintaining also.
Consult Fig. 2, it is the face upwarding stereogram of Fig. 1 or is called the stereogram that the kettle teapot with Fig. 1 position turns, so that see the situation that is provided with of electric heater 3 clearly.As shown in the figure, electric heater 3 be 2 baseplane at the bottom of the kettle the neighboring inwardly the mode of coiling be provided with, electric heater 3 has coiled a circle about half, the heating sucker rod that is used for generating heat extracts from the metal outer pipe of electric heater 3.Fig. 3 is the cutaway view along the A-A face.
Consult Fig. 3, clearly show that wherein brazing 4 that the metal outer pipe 3-1 of electric heater 3 is piled is welded at the bottom of the kettle 2 following periphery place.The heating sucker rod 3-3 of the heating of electric heater 3 has electric insulation layer 3-2, and it has the electric insulation effect, thereby heating sucker rod 3-3 can not be electrically connected with metal outer pipe 3-1.In addition, 2 neighboring protuberance at the bottom of the kettle.2 middle parts are planes at the bottom of the kettle, and its periphery extends upwardly to the certain altitude place and forms a little circular arc, extend downwards afterwards, flatten again, tilt upward again, upwarp part m and form.The flattening that upwarps part m and link to each other partly is the part that is connected with kettle body 1.The bottom perimeter of kettle body 1 inserts and upwarps the other flattened region of part m, pushes down the bottom perimeter of kettle body 1 by upwarping part m then, makes at the bottom of the kettle 2 to link together with kettle body 1.
