[0027] See Figures 1 - 4, the present utility model provides a microwave oven, which includes a cavity 1, a first heating component 2 and a first glass plate 3. The cavity 1 includes a side frame and a top plate 11 provided at the upper end of the side frame. The first glass plate 3 is provided on the bottom wall of the top plate 11 and encloses to form a first installation cavity. The first heating component 2 is disposed in the first installation cavity. Setting the first heating component 2 in the first installation cavity at the top of the cavity 1 can prevent the oil on the food from splashing onto the first heating component 2, greatly reducing the cleaning difficulty of the cavity 1. And a first glass plate 3 is provided at the bottom of the first heating component 2, so that the heat generated by the first heating component 2 is first transferred to the first glass plate 3 and evenly diffused on the first glass plate 3, and then transferred to the inside of the cavity 1 through heat radiation and heat convection to heat the food. While realizing the easy cleaning of the microwave oven, the heating of the microwave oven can be made more uniform. On the other hand, the glass has good heat conduction, which can ensure the heating efficiency inside the microwave oven and eliminate the defect that the temperature rise inside the cavity 1 is slow due to setting the first heating component 2 outside the cavity 1.

[0028] Further, a first groove 111 recessed upward is provided on the bottom wall of the top plate 11. The first glass plate 3 and the first groove 111 enclose to form the first installation cavity. Specifically, the first glass plate 3 seals the entire opening of the first groove 111. The size of the first glass plate 3 is larger than that of the first groove 111, so that the first glass plate 3 completely seals the first groove 111. After the heat generated by the first heating component 2 is evenly diffused through the first glass plate 3, it can directly enter the inside of the cavity 1 to heat the food.

[0029] Further, a first installation hole 112 and a second installation hole are provided on the top plate 11. The first installation hole 112 and the second installation hole are respectively located on two opposite side walls of the first groove 111.

The first heating component 2 passes through the first installation hole 112 to extend into the first groove 111, and both ends of the first heating component 2 are respectively inserted into the first installation hole 112 and the second installation hole. During installation, first pass the first heating component 2 through the first installation hole 112 into the first groove 111 until one end of the first heating component 2 is inserted into the second installation hole. At this time, the other end of the first heating component 2 still remains in the first installation hole 112, thereby realizing the fixation of the first heating component 2. In an exemplary embodiment, the second heating component 6 includes a plurality of first heating tubes, and the first heating tubes are strip-shaped stainless steel heating tubes.

[0030] Further, a shielding net 4 is provided on the bottom wall of the top plate 11, and the shielding net 4 covers the first groove 111. In an exemplary embodiment, the shielding net 4 is adhesively bonded to the bottom wall of the top plate 11, and the first glass plate 3 is adhesively bonded to the bottom wall of the shielding net 4 to fix the shielding net 4 and the first glass plate 3. The shielding net 4 covers the first groove 111, which can prevent the microwave in the microwave oven from leaking from the top, causing arcing in the first heating component 2 in the first groove 111.

[0031] Further, the cavity 1 includes a heat shield 5, the heat shield 5 covers the top wall of the top plate 11, and the first installation cavity is located inside the heat shield 5.

The microwave stirring assembly is located at the central position of the bottom plate 12 of the cavity 1. The waveguide box assembly 8 includes a waveguide box and a magnetron. The magnetron is installed on the waveguide box, and the rotation drive shaft is rotationally connected to the waveguide box. The magnetron can convert electrical energy into microwaves. When the microwaves are absorbed by food, the "polar molecules" such as water, sugar, and fat in the food vibrate at high speed. This process is what we see as "the food is heated", thus realizing microwave heating. The microwave stirring vane assembly 9 can continuously change the reflection mode of electromagnetic waves in the microwave oven by rotating the blades, and can disrupt the original fixed standing wave, making the heating intensity at different positions in the microwave oven more uniform.

[0036] Further, the microwave oven includes a door assembly 15. The cavity 1 further includes a front side plate 13. A through hole 14 is provided on the front side plate 13.

The first heating assembly 2, the first glass plate 3, the second heating assembly 6, and the second glass plate 7 are all arranged between the housing assembly 10 and the cavity 1. The housing assembly 10 can prevent users from directly contacting the internal structure of the microwave oven, avoiding potential safety hazards such as accidental contact burns to users.

[0038] Further, the housing assembly 10 includes a housing main body 101, a base 102, and a rear shell 103. The base 102 is disposed at the bottom of the housing main body 101. The rear shell 103 is disposed on the rear side wall of the housing main body 101. The housing main body 101, the base 102, and the rear shell 103 are enclosed and connected to form a receiving cavity with an opening at one end. The cavity 1 is disposed in the receiving cavity. The housing main body 101 is of an inverted U-shaped structure. The housing main body 101, the bottom shell, and the rear shell 103 are all fixedly connected by screws.
