Embodiment, broadly falls into the scope of protection of the invention.
Referring to Fig. 1 to Fig. 3, the present invention provides the electric cooking appliance of a kind of low noise, and for boiling liquid, described electric cooking appliance can
Think boiling water pot or stewing out of water electric cooking pot.Described electric cooking appliance includes that cooker body 3 and heater, described cooker body 3 include diapire 31 He
Upwardly extend the sidewall 32 of setting from described diapire 31, described diapire 31 surrounds to hold the receiving of liquid with described sidewall 32
Chamber 301, described heater includes the first heater 6 being located at described diapire 31 and is located at the second heating of described sidewall 32
Device 5, the liquid accommodated in chamber 301 described in described secondary heating mechanism 5 heated and boiled produces bubble from described sidewall 32.
Refer to Fig. 1 to Fig. 3, illustrate as a example by stewing out of water electric cooking pot below.The electric cooking appliance of described low noise includes
Base 7, the outer housing 2 being arranged on described base 7, the heater being located in outer housing 2 and cooker body 3, be positioned in cooker body 3 interior
Gallbladder 4 and be covered on the lid 1 in described cooker body 3.For stewing out of water electric cooking pot, described cooker body 3 is stewing out of water electric cooking pot
Outer pot, described cooker body 3 includes diapire 31 and from the described diapire 31 upwardly extending sidewall of periphery 32, described diapire 31 usually circle
Shape, described sidewall 32 usually cylindrical tube shape, described diapire 31 surrounds a receiving chamber 301 with sidewall 32, in order to hold water or its
His liquid to be heated.Certainly, described diapire 31 and sidewall 32 can also be other shapes.Described heater includes the first heating
Device 6 and secondary heating mechanism 5.Described first heater 6 is located at below described diapire 31, in order to heat receiving chamber from below
Water in 301.In the present embodiment, described first heater 6 is around discoid heat-generating pipe, in other embodiments, and institute
Stating first heater 6 can also be for solenoid or heating resistor sheet etc..Described secondary heating mechanism 5 is located at described sidewall 32
Periphery, described secondary heating mechanism 5 is positioned at the top of described diapire 31, and is arranged on the middle and lower part of described sidewall 32.At this
