The housing 1 is provided with a cavity 110. The waveguide box 5 includes an inlet 510 and an outlet 520. The inlet 510 is connected to the microwave generator. The lower end of the waveguide box 5 extends into the cavity 110 so that the outlet 520 penetrates the housing 1 and extends into the cavity 110, so that the outlet 520 is connected to the inside of the cavity 110. The microwaves generated by the microwave generator enter the cavity 110 through the inlet 510 and the outlet 520 in sequence to heat the food.

[0030] like Figure 2 and 3 In order to heat the food evenly, it also includes a stirring component, which includes a stirring bracket 2, a stirring shaft 3, a stirring blade 4 and a stirring motor. The stirring bracket 2 includes a sleeve 210, at least two upper limit protrusions 220 and at least two lower limit protrusions 230. The sleeve 210 is clamped at the outlet 520. The upper limit protrusion 220 and the lower limit protrusion 230 respectively limit the upper and lower positions of the sleeve, so that the stirring bracket 2 is directly clamped at the outlet 520, and the connection is firm. The upper limit protrusion 220 and the lower limit protrusion 230 limit the upper and lower positions of the stirring bracket 2, so that the stirring bracket 2 will not fall off, the reliability is high, and the reflection effect of the stirring component on the microwave will not be affected, thereby ensuring a good microwave heating effect. Specifically, when the sleeve 210 is clamped in the outlet 520, the lower end surface of the upper limit protrusion 220 abuts against the position of the inner bottom surface of the waveguide box 5 corresponding to the outlet 520, and the upper end surface of the lower limit protrusion 230 abuts against the bottom surface of the waveguide box 5. Figure 4 and 5 .

[0031] As an example, Figure 2 The upper end of the stirring shaft 3 is directly larger than the diameter of the lower end of the stirring shaft 3, the upper end of the stirring shaft 3 abuts against the upper end surface of the sleeve 210, the lower end of the stirring shaft 3 rotatably fits in the sleeve 210, and the lower end of the stirring shaft 3 extends downward in the cavity 110, so that the stirring shaft 3 can rotate and fit in the sleeve 210; the motor shaft of the stirring motor is connected to the upper end of the stirring shaft 3. Specifically, a connecting hole is provided on the upper end surface of the stirring shaft 3, and the motor shaft of the stirring motor is extended in the connecting hole to be connected with the stirring shaft 3. The connection is simple, and it is convenient for the motor shaft of the stirring motor to drive the stirring shaft 3 to rotate; the stirring blade 4 is connected to the lower end of the stirring shaft 3. Specifically, a fixing hole is provided at the lower end of the stirring shaft 3, and a threaded fastener is used to penetrate the stirring blade 4 and fix it in the fixing hole to fix the stirring blade 4, which is convenient for installation and disassembly.

[0032] Specifically, the stirring assembly and the threaded fastener are both plastic parts, which facilitates microwaves to pass through the gap between the stirring assembly and the emission port 520 and enter the cavity 110 .

[0033] Specifically, the waveguide box 5 includes an upper cover and a lower cover, and the upper cover and the lower cover are fixed together by bolts.

[0034] As an example, Figure 3 For ease of installation, the outer side surface of the upper limit protrusion 220 away from the center of the sleeve 210 is an inclined surface. When the stirring bracket 2 is installed from bottom to top in the cavity 110, the inclined surface of the upper limit protrusion 220 acts as a guide, making it easier for the sleeve 210 to be snapped into the outlet 520.

[0035] As an example, Figure 3 In order to facilitate installation and disassembly, the upper limit projection 220 can produce elastic deformation. Specifically, at least two support plates 211 are provided on the outer side of the sleeve 210, and the support plates 211 are distributed along the outer circumference of the sleeve 210. The upper limit projection 220 is provided on the outer side of the support plate 211 and the upper limit projection 220 corresponds to the support plate 211 one by one; there is a spacing between two adjacent support plates 211, and there is a spacing between the inner side of the support plate 211 and the outer side of the sleeve 210, so that the upper limit projection 220 is deformed when the support plate 211 is squeezed, so that the sleeve 210 is conveniently clamped in the outlet 520. Specifically, the lower end of the support plate 211 is provided on the sleeve 210, and the upper limit projection 220 is provided on the upper end of the support plate 211.

Specifically, in order to facilitate the arrangement of the support plate 211, the outer side of the sleeve 210 is provided with an annular protrusion 212 protruding from the outer side of the sleeve 210, and the support plate 211 is arranged on the annular protrusion 211, which also makes the entire stirring bracket 2 high in strength. Specifically, the cross-section of the upper limit protrusion 220 is a right-angled trapezoid, which facilitates the upper limit protrusion 220 to be inserted into the outlet 520 for installation, and also facilitates the upper limit protrusion 220 to be separated from the outlet 520 for disassembly.

Specifically, the annular protrusion 211 is located at the lower end of the shaft sleeve 210, so that the lower limit protrusion 230 is conveniently provided on the annular protrusion 211.

[0037] As an example, Figure 3The lower limit projection 230 includes a reinforcing plate 231 and at least one convex block 232. The reinforcing plate 231 is used to strengthen the strength of the shaft sleeve 210. The convex block 232 is arranged on the outer surface of the reinforcing plate 231. The convex block 232 is used to abut against the bottom surface of the waveguide box 5 to realize the lower limit of the stirring bracket 2. Specifically, there are two convex blocks 232, which are respectively located on both sides of the left side of the reinforcing plate 231, and the strength is higher.

[0038] As an example, Figure 3 , the outer side of the sleeve 210 is also provided with an extrusion protrusion 213; when the sleeve 210 is clamped in the outlet 520, the extrusion protrusion 213 is squeezed on the inner side wall of the outlet 520, so that the sleeve 210 is clamped in the outlet 520, and it will not rotate circumferentially, and the reliability is high. Specifically, the extrusion protrusion 213 is provided on the outer side of the reinforcing plate 231, and the extrusion protrusion 213 corresponds to the reinforcing plate 231 one by one, so that the reinforcing plate 231 has high strength and is not easy to deform. Specifically, when the number of the protrusions 232 is two, the extrusion protrusion 213 is located above the protrusion 232, and the extrusion protrusion 213 and the two protrusions 232 are distributed in a triangle, so that the strength of the sleeve 210 and the reinforcing plate 231 is further improved.

[0039] As an embodiment, in order to facilitate fixing the waveguide box 5 on the housing 1, it also includes a mounting plate 6, the mounting plate 6 is fixed to the upper surface of the housing 1 by bolts, and the waveguide box 5 is fixed to the mounting plate 6 by bolts.

[0040] Specifically, the principle of the utility model is to respectively provide an upper limit protrusion 220 and a lower limit protrusion 230 on the outer side of the sleeve 210, so that the sleeve 210 is stuck on the shell 1, and at the same time, the upper limit protrusion 220 and the lower limit protrusion 230 are used to limit the upper and lower positions of the stirring bracket 2, which has high reliability, the stirring bracket 2 is not easy to fall off, and the microwave heating effect is ensured.

[0041] Action process: Install the stirring assembly: 1. The sleeve 210 is clamped in the outlet 520 from bottom to top, the upper limit protrusion 220 is squeezed, the support plate 211 is deformed, and the support plate 211 swings toward the center of the sleeve 210, so that the sleeve 210 is clamped in the outlet 520; 2. Continue to push the sleeve 210 upward until the upper limit protrusion 220 extends into the waveguide box 5. At this time, the upper limit protrusion 220 is reset and abuts against the inner bottom surface of the waveguide box 5, and the lower limit protrusion 230 abuts against the outer bottom surface of the waveguide box 5; 3. The stirring shaft 3 is installed in the sleeve 210; 4. Use threaded fasteners to install the stirring blade 4 on the stirring shaft 3.
