Detailed description of the invention
With reference to accompanying drawing.
A kind of electric kettle, comprise kettle main body and be electrically coupled with it base assembly 6 be connected, described kettle main body comprises Handleset 1, pot lid assembly 2, comprises Hu Zui and the kettle body assembly 3 in the liquid containing chamber of five metals material, the heat generating component 4 be arranged in the exterior bottom of described liquid containing chamber, the bottom assembly 5 that is connected with heat generating component 4.
Described liquid containing chamber comprises kettle body 3-1 and back cover sheet 3-2, the seamless cavity volume that upper kettle body 3-1 and the seamless butt welding of back cover sheet 3-2 are formed, back cover sheet 3-2 has the radian to lower convexity, like this after back cover sheet 3-2 completes with upper kettle body 3-1 butt welding, the closed containing cavity of kettle body defines a smooth smooth entirety, outwardly bottom makes the bottom in liquid containing chamber when being heated generation distortion, the extension direction of its bottom integrated downward, and be convenient to cleaning and wiping, and the bottom recessed as common electric kettle and gap between kettle body inwall, can not be formed, incrustation is caused to be not easy to remove.
Described liquid containing chamber is on the whole without vision visible gap, and the exterior bottom edge in liquid containing chamber is provided with reinforced company's relay part of five metals material continuous or spaced apart.
Heat generating component 4 is connected in the centre of back cover sheet 3-2, described reinforced company relay part is arranged at the outer region of described heat generating component 4 on described back cover sheet 3-2, and described reinforced company relay part comprises stiffening ring 13 and at least 2 connection code sons 14 be connected on stiffening ring 13.
The thickness of described stiffening ring 13 is 0.8-1.2 times of back cover sheet 3-2 thickness; The thickness of stiffening ring should not be excessively thin, otherwise insufficient strength, and stiffening ring is unsuitable blocked up, and the excessive stiffening ring of thickness can affect internal structure at the bottom of kettle, and be expressed to other assembly, therefore, the thickness of stiffening ring 13 is preferably suitable with the thickness of back cover sheet 3-2.
The inner side of the inner ring of stiffening ring 13, outer ring or inner ring and outer ring adopts boxing to be welded on back cover sheet 3-2; As shown in Figures 2 and 3, the position in figure shown in A is the weld of boxing, can be welded on back cover sheet 3-2 by the inner side of the inner ring of stiffening ring 13 and outer ring simultaneously, when intensity is enough, also can only by boxing inside inner ring or inside outer ring on back cover sheet 3-2.
Described bottom assembly 5 comprises annular sidewall 5-1 and base plate 5-2, described base plate 5-2 has the nearly heart region 5-3 be connected with described the heat generating component 4 and outer peripheral areas 5-4 be connected with described annular sidewall 5-1, nearly heart region 5-3 refers to the region of geometric center position base plate 5-2 being positioned at bottom assembly 5, and outer peripheral areas 5-4 refers to the baseplate zone beyond nearly heart region 5-3.
Described nearly heart region 5-3 is connected with described heat generating component 4 by connector, and nearly heart region 5-3 arranges bolt hole, and bottom assembly 5 is connected on heat generating component 4 by bolt passing through bolt hole; Stiffening ring 13 is welded on the outside of outer peripheral areas 5-4.
Position relationship between bottom assembly 5 with kettle body assembly 3 is: the top edge of annular sidewall 5-1 coordinates with seamless contact the in the bottom of back cover sheet 3-2; Bottom assembly 5 is by being assembled on electric kettle with being fixedly connected with of heat generating component 4, the height Q2 of bottom assembly 5 is greater than the distance Q1 between the bottom of bottom assembly 5 after actual installation and back cover sheet 3-2, like this, close contact between the top edge of the annular sidewall of the bottom assembly 5 after installation and back cover sheet 3-2, form seamless contact to coordinate, the outside of electric kettle forms overall jointless structure.
Be provided with at least two L shape reinforcement 5-5 in bottom assembly 5, the circumference of L shape reinforcement 5-5 annularly sidewall 5-1 is uniform and be positioned on annular sidewall 5-1 and base plate 5-2 inner surface; The inner surface of L shape reinforcement 5-5 perpendicular to the annular sidewall 5-1 at its place and the inner surface of base plate 5-2.
The bottom of bottom assembly 5 is provided with at least 3 spacing preiection 5-6 for support base cap assemblies 5, when the sinking amplitude of bottom assembly 5 is excessive, spacing preiection 5-6 contacts with base assembly 6, further support base cap assemblies 5, at least 3 spacing preiection 5-6 are distributed in the bottom of bottom assembly 5, determine the principle in face according to 3, play the stable supporting role to whole bottom assembly 5.
The one end connecting code son 14 is fixedly connected on outside stiffening ring 13 by the mode of butt-joint, and the other end connecting code son 14 is fixedly connected with bottom assembly 5 is removable by the mode of screw or button bit; The number of connection code son 14 is at least 3, and according to the principles of 3 fixed one sides, the code son of more than 3 or 3 can ensure that bottom assembly can be fixed in one plane by the connection between code son and bottom assembly.
The effect connecting code son 14 is: when electric heating kettle heating, produce thermal expansion at the bottom of kettle due to the intensification of heat generating component 4 when upholding distortion downwards, to ensure to be connected on heat generating component 4 and to coordinate with seamless contact the between bottom kettle body with the bottom assembly 5 that heat generating component 4 moves down simultaneously.Found by long-term experiment and practical application, cannot function as described above bottom the kettle body only code son 14 being directly welded on electric kettle, reason is as follows: when electric heating kettle heating, the position heat at heat generating component 4 place sharply rises, the corresponding site of the back cover sheet 3-2 bottom the kettle body of welding is heated and upholds distortion downwards, other positions of back cover sheet 3-2 also can produce corresponding distortion, the position at heat generating component 4 place is called heat transfer region, heat transfer region is heated and upholds the distance of being out of shape downwards is M1, the distance that the region at stiffening ring 13 place is out of shape downwards is M2, because the temperature of heat generating component 4 and region is far away higher than the temperature in other place bottom kettle body, according to expansion principle, the distance M1 that heat transfer plate 4-1 region moves down is far longer than other region bottom kettle body, namely M1 is greater than M2, therefore the dynamics of the stressed bolt be connected with bottom assembly 5 on heat transfer plate 4-1 of code son 14, and direct spot welding as young in code is bottom kettle body, it will be code son place local pressure.When pulling force is greater than the deformation force of kettle body board material, the distortion at code son place bottom kettle body can be caused.Along with the working time is longer, be out of shape larger, have a strong impact on kettle body internal look.Do not reach seamless smooth effect.Also have the young direct spot welding of code also having to kettle body the risk that spot welding punctures kettle body, cause kettle body to leak.Also have the weldering trace because spot welding exists, affect kettle outer; Kettle body bottom increases by a circle stiffening ring 13, young 14 of code is welded on stiffening ring 13, be hold whole stiffening ring, and stiffening ring 13 is that boxing is bottom kettle body when code son is stressed, so lifting surface area can be whole bottom, do not have the risk of local deformation and affect kettle body outward appearance.
