Detailed description of the invention
With reference to accompanying drawing 1-7.
A kind of electric kettle, comprise kettle main body and be electrically coupled with it base 6 be connected, described kettle main body comprises Handleset 1, pot lid assembly 2, comprises Hu Zui and the kettle body assembly 3 in liquid containing chamber, 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 is formed by upper kettle body 3-1 and the seamless butt welding of back cover sheet 3-2, described back cover sheet 3-2 has the radian protruded downwards, as shown in Figures 6 and 7, like this after back cover sheet 3-2 completes with upper kettle body 3-1 butt welding, described liquid containing chamber is on the whole without vision visible gap, form 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 bottom assembly 5 comprises annular sidewall 5-2 and base plate 5-3, the external diameter Q3 of described annular sidewall 5-2 is less than the external diameter Q6 bottom kettle body assembly 3, the bottom of described kettle main body combines with the top edge of described annular sidewall 5-2, the bottom of kettle main body combines with the top edge of described annular sidewall 5-2 and specifically refers to: the top edge of annular sidewall 5-2 contacts with back cover sheet 3-2 and coordinates, and contact between the two coordinates for seamless contact coordinates.
Described base plate 5-3 is provided with the elastically deformable region 5-6 distributed continuously or intermittently of positional symmetry distribution centered by its geometric center.Described base plate 5-3 has the nearly heart region 5-4 be connected with described the heat generating component 4 and outer peripheral areas 5-5 be connected with described annular sidewall, described elastically deformable region 5-6 is between described nearly heart region 5-4 and described outer peripheral areas 5-5, described nearly heart region refers to the region of geometric center position base plate 5-3 being positioned at bottom assembly 5, and described outer peripheral areas refers to the periphery in nearly heart region.
Described bottom assembly 5 is formed in one part, described in the Thickness Ratio of described elastically deformable region 5-6, nearly heart region 5-4 and/or described outer peripheral areas 5-5 is thin, when nearly heart region 5-4 along with heat generating component 4 be heated move down time, thus elastically deformable region 5-6 can block stressed transmission between nearly heart region 5-4 and outer peripheral areas 5-5 by the elastic deformation of self because its thickness is thin compared with other positions of base plate, thus makes outer peripheral areas 5-5 can not be subject to nearly heart region 5-4 to sink the impact of movement.
Described elastically deformable region 5-6 is the ring-shaped depression 5-1 distributed centered by the geometric center of this bottom assembly 5, and the position of described ring-shaped depression 5-1 on described base plate 5-3 is: the average distance between described ring-shaped depression 5-1 and described nearly heart region 5-4 is less than the average distance between described ring-shaped depression 5-1 and described outer peripheral areas 5-5.
The degree of depth of described ring-shaped depression 5-1 is the 1/2-1/4 of the base plate 5-3 thickness of described bottom assembly 5, be preferably 1/3, the thickness of ring-shaped depression 5-1 position should not be excessively thin, otherwise the intensity of whole base plate 5-3 can be affected, when the degree of depth of ring-shaped depression 5-1 is the 1/2-1/4 of base plate 5-3 thickness, the requirement of elastically deformable can be reached.
Be provided with at least two L shape reinforcement 5-7 in bottom assembly 5, the circumference of L shape reinforcement 5-7 annularly sidewall 5-2 is uniform and on the inner surface of annular sidewall 5-2 and the plate inner surface between ring-shaped depression 5-1 and annular sidewall 5-2; The inner surface of L shape reinforcement 5-7 perpendicular to annular sidewall 5-2 and the inner surface of base plate 5-3, the position being provided with reinforcement is not yielding.
Described bottom assembly 5 is connected with described heat generating component 4 by least two connectors being arranged on described nearly heart region place, and specifically, nearly heart region 5-4 is provided with bolt hole, and bottom assembly 5 is connected on heat generating component 4 by bolt passing through bolt hole.
The bottom of described bottom assembly 5 is provided with at least 3 spacing preiection 5-8 for support base cap assemblies 5, when the sinking amplitude of bottom assembly 5 is excessive, spacing preiection 5-8 contacts with base assembly 6, further support base cap assemblies 5, at least 3 spacing preiection 5-8 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.
Electric kettle of the present invention during fabrication, first be shaped upper kettle body 3-1 and back cover sheet 3-2, then by upper kettle body 3-1 and back cover sheet 3-2 to being welded into a seamless cavity volume, heat generating component 4 soldering formed by heat transfer plate 4-1 and heat-generating pipe 4-2 is again in the bottom of back cover sheet 3-2, bottom assembly 5 is bolted on 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, the top edge of the annular wall of the bottom assembly 5 after installation with form tight seamless contact because interference combines between back cover sheet 3-2 and coordinate.
When electric heating kettle heating, the position at heat generating component 4 place forms thermal deformation because heat sharply rises at the bottom position of kettle body assembly 3, namely the bottom of back cover sheet 3-2 produces distortion sinking, the heat generating component 4 be welded on bottom back cover sheet 3-2 also sinks thereupon, the bottom assembly 5 be fixedly connected on heat generating component 4 also and then sinks, now, ring-shaped depression 5-1 place due to other positions bottom its Thickness Ratio bottom assembly 5 thin, more easily stressed, therefore, it is possible to play the blocking effect to stressed transmission between nearly heart region 5-4 and outer peripheral areas 5-5, namely when nearly heart region 5-4 sinks along with heat generating component 4, ring-shaped depression 5-1 absorbs the stressed of the sinking that nearly heart region 5-4 passes over by the deformation of self, and make the outer peripheral areas 5-5 being in ring-shaped depression 5-1 periphery can not receive the impact of sinking active force, therefore, remain that at the position that back cover sheet 3-2 contacts with bottom assembly 5 tight seamless contact coordinates, whole kettle body still keeps seamless sealing state.
