Abstract
An electrothermal-electric combined utensil comprises a container with a heater, a driving motor for stirring, a big body and a base, the base is provided with a power wire and a lower connector, an upper connector of the big body is plugged into the lower connector, and the power wire is provided with an anti-interference part, which is connected in series or in parallel with an electronic board on the big body. The anti-interference part comprises a common-mode inductor, which is connected with the conductors in the power wire. Because the common-mode inductor added on the power wire not only can filter common-mode electromagnetic interference on the connecting wire and but also can inhibit self electromagnetic interference from being transmitted to the outside, the normal operation of other electronic devices in the same electromagnetic environment cannot be affected; when the utensil is used along with the electronic board, the anti-interference performance of the whole machine can be better enhanced; and meanwhile, the utensil is characterized by no signal attenuation, small size, convenience in use and high balance degree.

Among the figure: 1 is container, and 2 is drive motors, and 3 is electron plate, and 3.1 is input, and 3.2 is output, and 4 is last connector, and 5 is lower connector, and 6 is common mode inductance, and 7 is power line, and 8 is electric capacity, and 9 is base.
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 5, this electric heating electric combined utensil comprises the container 1 that has heater, the drive motors 2 that is used to stir, bodice and base 9, and heater is arranged at the bottom of container 1, the inner chamber of container is provided with mixing component, and the bottom of mixing component connects drive motors 2.Base 9 is provided with power line 7 and lower connector 5, and this lower connector 5 links to each other with the mutual grafting of the last connector 4 of bodice.Electron plate 3 is arranged in the combined utensil.Drive motors 2 and heater are electrically connected with electron plate 3 respectively, to realize heating and agitating function.
Because machine has agitating function, when drive motors 2 work, the wiring of machine connection wire is subjected to spatial limitation, cause the strong and weak electricity connecting line to intersect, situation such as can not clocklike distribute all produces bigger electromagnetic interference to electrical network, therefore power line 7 is provided with anti-interference parts, and the electron plate 3 on these anti-interference parts and the container 1 is connected in series.These anti-interference parts are common mode inductance 6, and common mode electromagnetic interference on the common mode inductance 6 one side energy filtering connecting lines can inhibition itself outwards not sent electromagnetic interference again on the other hand, avoids influencing the operate as normal of other electronic equipments under the same electromagnetic environment.
Wire interconnects in common mode inductance 6 and the power line 7 connects; Common mode inductance is wrapped in the power line, sees Fig. 2.Common mode inductance 6 is played a protective role, prolong its useful life.Common mode inductance 6 and power line 7 be for being connected in series, and be connected with L/N two inputs of electron plate 3.Two electric capacity 8 are set on the output 3.2 of electron plate 3.The output 3.2 of electron plate 3 and electric capacity 8 are for being connected in series, and be connected with ground wire. see Fig. 5, electron plate 3 is used with common mode inductance 6, when the normal current in the circuit is flowed through common mode inductance 6, electric current produces reverse magnetic field and cancels out each other in the inductance coil of same-phase coiling, this moment, the normal signal electric current mainly was subjected to the influence of coil resistance, produced less damping.When common mode current is flowed through common mode inductance 6, because the same tropism of common mode current, can in the coil of common mode inductance 6, produce magnetic field in the same way, thereby increase the induction reactance of coil, make coil show as high impedance, produce stronger damping, with this attenuation common-mode electric current, reach the purpose of filtering, can better improve complete machine device interference free performance.It is unattenuated that simultaneously it has signal, and volume is little, easy to use and have the good characteristics of the degree of balance, and meet China conducted interference and radiated emission are had the relevant requirement for restriction and the safety standard of European Union.
