Wherein, the shape that at least a portion of blast pipe 3 is spiral pipeline refers to, at least a portion of blast pipe 3 extends spirally around fixed axis (can be straight line or curve).The shape that at least a portion of blast pipe 3 is roundabout pipeline refers to, blast pipe 3 at least a portion comprise straight sections and arc tube connector portion, wherein straight sections is at least two, and arc tube connector portion is at least one, and arc tube connector portion is cascaded straight sections to form blast pipe 3.
In embodiment more of the present utility model, heater 4 is coated on the outer surface of blast pipe 3.Thus, make the simple in structure of blast pipe 3, be convenient to the formation of blast pipe 3.
Certainly, heater 4 and blast pipe 3 can also for example, have heating chamber (not shown) by other fit form in heater 4, and blast pipe 3 is communicated with described heating chamber.Thus, can improve the efficiency that heater 4 is connected with blast pipe, and heat because gas directly enters in the heating chamber of heater 4, can improve the efficiency of heating surface of heater 4.
Advantageously, blast pipe 3 and heater 4 by welding, be threaded or bolt is connected.Thus, make blast pipe 3 and heater 4 easy to connect, and efficiency of assembling is high, but also can improves the sealing property of the junction of heater 4 and blast pipe 3.
As shown in the figure, blast pipe 3 comprises the first air intake pipeline section 31 that is positioned at heater 4 front sides and the second air intake pipeline section 32 that is positioned at heater 4 rear sides, wherein the front side of heater 4 and rear side are according to airflow direction and fixed, particularly, the first air intake pipeline section 31 is between heater 4 and air inlet 201, and the second air intake pipeline section 32 is between heater 4 and air outlet 202.Because the temperature of the first air intake pipeline section 31 is lower, higher to the heating effect of gas temperature poor and the second air intake pipeline section 32, better to the heating effect of gas, therefore, in embodiment more of the present utility model, the first air intake pipeline section 31 is straight tube, and the second air intake pipeline section 32 is bend pipe.Thus, not only can make air-flow enter rapidly in cooking cavity, to improve the cooking efficiency of electric cooker, but also can heat fully air-flow, improve the heating effect of 4 pairs of air-flows of heater.
In addition, heater 4 is cellular heater or ptc heater.Thus, make the simple in structure of heater 4, and the efficiency of heating surface is high, security is good.
Advantageously, heater 4 is provided with for regulating the temperature-adjusting device (not shown) of the heating-up temperature of heater 4.Thus, can regulate easily the heating-up temperature of heater 4, so that the gas that air inlet pipe 3 is discharged reaches predetermined temperature, but also can avoid the heater 4 that heater 4 excess Temperatures cause to damage.
Preferably, the porch of blast pipe 3 is provided with the fan 6 that enters blast pipe 3 for driving gas.Thus, can make air-flow by blast pipe 3, enter cooking cavity fast, thereby improve the cooking efficiency of electric cooker.
The electric cooker that an embodiment of the utility model has been shown in Fig. 1, in figure, arrow shows the flow direction of gas.
According to the electric cooker of the utility model embodiment, on upper cover 2, be formed with air inlet 201 and air outlet 202, and in upper cover, be provided with blast pipe 3, and blast pipe 3 is provided with heater 4.The entrance of blast pipe 3 is entrances of gas or gas liquid mixture, and heater 4 is the heater of steam or other gases.Heater 4 and blast pipe 3 can be splits, and heater 4 is wrapped in the surface of blast pipe 3.In addition, heater 4 can also be threaded connection with blast pipe 3, welding, bolt are connected, and the modes such as compression fit link together.Gas or gas liquid mixture can directly enter heater 4 and bending structure need not be set, and just in the rear end of heater 4, bending structure are just set.Heater 4 has temperature auto-adjusting circuit, preferred, selects PTC as heater.Heater also can be selected honeycomb heating element.
Blast pipe 3 is bend pipe, increases the path of gas in blast pipe 3, extends the heat time of gas, the temperature while improving gas discharge.
