The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings cooking apparatus 100 according to an embodiment of the present invention is described, the cooking apparatus 100 can be roasting
The equipment such as case, micro-wave oven.
As shown in Fig. 1-Fig. 7, cooking apparatus 100 according to an embodiment of the present invention includes cabinet 10, heat generating member 30 and antenna
Component.
Cooking cavity is limited in cabinet 10, for placing food to be cooked, heat generating member 30 is set in cabinet 10, for example,
Heat generating member 30 can be heat-generating pipe, and heat generating member 30 is mainly made of heater and heat carrier, and heater is located at the inside of heat carrier,
So that the heat of heater can be transferred to heat carrier, thus using the food in heat carrier heating heating chamber 11, meanwhile,
It is insulated from each other between heater and heat carrier, cause heat carrier to charge after being powered to avoid heater, and then influence antenna sets
The radiation effect of part.
Antenna module mainly includes current feed department 20 and irradiation unit, and one end of current feed department 20 is connected with microwave source, the other end with
Irradiation unit is connected, thus by the microwave energy transfer of microwave source to irradiation unit, and then pass through in irradiation unit feed-in heating chamber 11, it is real
Now to the microwave heating of food in heating chamber 11, achieve the purpose that auxiliary heating.
Further, heat carrier forms the irradiation unit, that is to say, that antenna module and heater share heat carrier, lead
Hot body both plays the role of the effect of transmitting fever body heat content and protective separation heater, meanwhile, heat carrier also functions to radiation
The effect of microwave energy, to reduce number of components, and then reduce manufacturing cost, and can reduce by sharing heat carrier
The space hold of component is set as two individual components compared to the irradiation structure by heat-generating pipe and antenna in the related technology
Scheme, the interference for the heat-generating pipe that can be subject to avoid the setting of the irradiation structure of antenna.
