Embodiment
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the application can phase
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As shown in Figures 1 to 5, the embodiment provides a kind of composite bottom cooking utensils, the composite bottom cooking utensils to include pot
Body 10 and magnetic conduction heating member 20, multiple through holes 21 are offered on magnetic conduction heating member 20, magnetic conduction heating member 20 is connected to a pot body
On 10 bottom surface, the composite bottom cooking utensils of the present invention are heated with cooking food using electromagnetic oven, can also be by the composite base
Cooker, which is placed on to directly heat on flame, carrys out cooking food.In the present invention, multiple through holes 21 are evenly distributed on magnetic conduction heating member 20
On, and it is ε that the area summation of multiple through holes 21, which accounts for the percentage of the area of magnetic conduction heating member 20, and ε scope be 40%≤ε≤
90%.
The pot body 10 of the composite bottom cooking utensils and the composite molding of magnetic conduction heating member 20, and control magnetic conduction heating member by adjusting
The area ratio of the area summation of 20 multiple through holes 21 and the gross area of magnetic conduction heating member 20 is to adjust magnetic conduction heating member 20 and pot
Contact area between body 10.Because the area sum of all through holes 21 and the area of the gross area of magnetic conduction heating member 20 are than straight
Deflection of the bottom for influenceing magnetic conduction efficiency and pot body 10 in heating is connect, applies the technical scheme of the present invention and enters area ratio
Row optimization, along with multiple through holes 21 of the present invention are evenly distributed on magnetic conduction heating member 20 so that magnetic conduction heating member 20 and pot
Contact uniformly between body 10, it is thus achieved that rapidly and uniformly being conducted heat between magnetic conduction heating member 20 and pot body 10, eliminate
The bottom of pot body 10 because thermal stress is uneven be deformed the problem of.
When area is than ε ＞ 90%, the magnetic conduction efficiency of magnetic conduction heating member 20 is low, and electromagnetic oven heating speed is too slow, have impact on
The normal use of the composite bottom cooking utensils.When area is than ε ＜ 40%, the bottom of pot body 10 is heated rear caused deflection
Greatly.
Because multiple through holes 21 on the magnetic conduction heating member 20 in the present invention are uniformly distributed so that magnetic conduction heating member 20 with
After pot body 10 connects, uniformly contacted between magnetic conduction heating member 20 and pot body 10 so that electromagnetic oven in heating, cook a meal by the composite base
During tool, magnetic conduction heating member 20 can be considered the thermal source heated to pot body 10, and magnetic conduction heating member 20 can enter to pot body 10
Row uniformly heating, i.e., thermal source is dispersed, farthest avoids deformation effect of the thermal stress to the bottom of pot body 10.
As shown in Fig. 2 the thickness of magnetic conduction heating member 20 is a, in an embodiment of the present invention, thickness a scope is：
0.1mm≤a≤0.6mm.Magnetic conduction heating member 20 is embedded in the bottom surface of pot body 10, that is, ensures magnetic conduction heating member 20 and pot
There is the surface to contact with each other between body 10.
As the thickness a ＞ 0.6mm of magnetic conduction heating member 20, the depth that rib 210 is embedded in the bottom of pot body 10 is excessive, then machine
Tool stress is larger, so that the bottom of pot body 10 is easily deformed, and cause the bottom of pot body 10 and through hole 21 it
Between be not easy it is smooth and full, it is uneven so as to cause to heat, conduct heat.As a ＜ 0.1mm, then embedded depth can be caused inadequate,
Adhesion between magnetic conduction heating member 20 and pot body 10 is small and magnetic conduction heating member 20 is easily come off.
Specifically, magnetic conduction heating member 20 also includes the rib 210 between being located at per two neighboring through hole 21, per two neighboring
Separated between through hole 21 by rib 210.Magnetic conduction heating member 20 is compressed on the bottom surface of pot body 10, and cause magnetic conduction heating member 20 with
The bottom surface of pot body 10 is concordant.The magnetic conduction heating member 20 of the present invention is in netted, and it is stretched rear using high magnetic conductive metal piece
Into the through hole on magnetic conduction heating member 20 can be formed during stretching, without being obtained again by punching.The present invention's leads
Magnetic heating member 20 is compounded in the bottom surface of pot body 10 using the method for cold riveting processing, is compounded to form together after cold riveting is processed
The mechanical stress of pot body 10 and magnetic conduction heating member 20 is smaller and distribution is more uniform so that bottom of the mechanical stress to pot body 10
The influence of portion's deformation reduces.Also, because magnetic conduction heating member 20 is cold riveting in the bottom of pot body 10, it can produce between the two
Excellent adhesion, the problems such as efficiently avoid the coming off of magnetic conduction heating member 20, bubbling, flange, extend composite bottom cooking utensils
Service life.
It is, of course, also possible to magnetic conduction heating member 20 and pot body 10 are processed and be combined into using techniques such as friction pressure welderings
Type.Through hole 21 is crowded with the filling of pot body 10 of composite bottom cooking utensils after composite molding so that magnetic conduction heating member 20 and pot body 10
Between contact abundant, heat transfer direction is more, heat transfer faster evenly, and adhesion is more preferable, so as to reduce thermal stress to pot sheet
The deformation effect of the bottom of body 10.Present invention improves the thermal shock stress when mechanical stress of the bottom of pot body 10 and heating,
Fundamentally reduce deflection.Heat transfer direction of the magnetic conduction heating member 20 to pot body 10 more causes homogeneous heating, and cooks a meal
The outward appearance of tool is more smooth attractive in appearance.
With reference to shown in referring to Fig. 3 to Fig. 5, a width of b of muscle of the rib 210 between two neighboring through hole 21, in the range of：
0.1mm≤b≤0.8mm。
As 210 width b ＞ 0.8mm of rib, the combination process between magnetic conduction heating member 20 and pot body 10 requires higher,
And mechanical stress larger between the two is easily caused, then causes the bottom of pot body 10 that larger deformation occurs.As b ＜
During 0.1mm, processing difficulties of magnetic conduction heating member 20, also, between magnetic conduction heating member 20 and pot body 10 after the completion of cold riveting, both it
Between adhesion it is small, while also cause magnetic conduction heating member 20 permeability it is low.
In an embodiment of the present invention, the thickness a of the width b of rib 210 and above-mentioned magnetic conduction heating member 20 is mutual in technique
Association, it is：The small then b of a are small, and then b is big greatly by a.Preferably, muscle wide 0.1mm to 0.2mm, thickness 0.2mm to 0.5mm；Or muscle
Wide 0.1mm to 0.26mm, thickness 0.1mm to 0.26mm.
In an embodiment of the present invention, the shape of the external periphery outline of magnetic conduction heating member 20 and the bottom shape of pot body 10
It is adapted, it is preferable that be circle.
Above-mentioned pot body 10 includes pot body 11 and pot bottom.Wherein, pot bottom includes curved transition sections 12 and flat bottoms 13,
Pot body 11 is connected with flat bottoms 13 by curved transition sections 12.In the present embodiment, heated only in flat bottoms 13 covered with magnetic conduction
Part 20.During heating, magnetic conduction heating member 20 may be regarded as thermal source, and 20 most surfaces of magnetic conduction heating member contact with flat bottoms, can be with
Increase the heat-transfer area of magnetic conduction heating member 20, so as to reach the purpose quickly heated.In other embodiments, flat bottoms 13 and extremely
Covered with magnetic conduction heating member 20 on small part curved transition sections 12, the adhesion between magnetic conduction heating member 20 and pot body 10 is strong.
