Micro-wave oven with baking function

Abstract

The invention relates to a microwave oven with barbecue function. The microwave oven comprises an external box body, a heating cavity body, an electric control room, an oven door and a barbecue grill with two ends which are respectively connected with the middle parts of two side surfaces of the heating cavity body and a centrosymmetric shape, and the barbecue grill can rotate and comprises a body which is positioned in the middle part and shaped like a broken line in a plane, vertical parts which are formed by extending from the two ends of the body along the direction which is perpendicularto the plane and fixed parts which are formed by outward extending from the tail ends of the vertical parts along the horizontal direction. The barbecue grill in the microwave oven with barbecue function has the centrosymmetric structure, so that when the barbecue grill is positioned in upper and lower gears, the barbecue grill can realize the same area of thermal radiation, thereby achieving thesame heating effect and having good uniformity of food cooking. The two side surfaces of the barbecue grill can be utilized as radiating surfaces, thereby being capable of reducing the corrosion degree of one side surface thereof and effectively prolonging the service life thereof. As the barbecue grill can realize the overturning automatically, the degree of automation is high and the safety is good.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven with a barbecue function. Background technique [0002] Generally, a microwave oven is a device that uses microwaves of about 2450 MHz per second emitted by a magnetron as a heating source to heat food by destroying the molecular arrangement in the food, thereby using the frictional heat generated between molecules. Wherein the microwave oven with grilling function can also utilize the radiant energy produced by the grilling tube arranged inside it to grill food. figure 1 It is a three-dimensional view of the external structure of a microwave oven with a barbecue function in the prior art. figure 2 for figure 1 A three-dimensional view of the internal structure of the microwave oven shown. Such as Figure 1 ~ Figure 2 As shown, this prior art microwave oven 1 with barbecue function mainly includes: an external box body 2 constituting the external structure of the microwav...

Problems solved by technology

But there is following problem in this prior art microwave oven with barbecue function: as mentioned above, because the barbecue pipe 11 in this microwave oven is fixed on the top surface of heating cavity 4, only one side can be used as radiation on it. and when grilling, the fat from the food will inevitably splash onto the radiating surface, causing corrosion on that side, which shortens its lifespan as it is prone to damage

But there is following problem in this prior art heater: as image 3 As shown, the heater 60 is composed of a heater body 62, a vertical portion 64 and a fixed portion 66, wherein one side of the heater body 62 is linear, and the other side is curved, that is, it belongs to a non-centrosymmetric structure, so when After it is rotated 180°, it cannot achieve equal-area heat radiation, so that the uniformity of heating cannot be guaranteed.

In addition, because the curved part is mainly concentrated in the center of one side, that is, the heat radiation area at the center is large, so the temperature at this part is relatively high, and as a result, the food under this part is prone to local overcooking.

In addition, when the heater 60 needs to be turned over, it needs to be done manually, which not only has the risk of scalding, and the degree of automation is low, but also occurs between the heater 60 and the food if it is not properly operated when grilling food with a large volume. interference problem
