[0028] Example

[0029] See also Figure 1 The utility model discloses a microwave oven, which includes a microwave oven body and a fan filter plate structure 50, and the fan filter plate structure 50 is arranged on the microwave oven body. The microwave oven body includes a cavity assembly 10, an outer cover 20, an oven door assembly 30 and a bottom plate assembly 40, and an installation space 101 is provided on one side of the cavity assembly 10. The outer cover 20 is arranged on the cavity assembly 10 from top to bottom, the bottom plate assembly 40 is arranged at the bottom of the cavity assembly 10, the oven door assembly 30 is arranged at the front end of the cavity assembly 10, and the fan filter plate structure 50 is arranged in the installation space 101.

[0030] Please also read Figure 2 and Figure 3The fan filter board structure 50 of the present solution includes a fan assembly 1, a fan bracket 2 and a filter board assembly 3. The fan assembly 1 is mounted on the fan bracket 2. The fan bracket 2 is provided with a first clamping portion 21. The filter board assembly 3 is provided with a second clamping portion 31. The filter board assembly 3 is detachably mounted on the fan bracket 2 through the matching connection between the second clamping portion 31 and the first clamping portion 21. With such a design, on the one hand, the detachable connection between the first clamping portion 21 and the second clamping portion 31 facilitates the installation of the filter board assembly 3 on the fan bracket 2, which can improve production efficiency and facilitate the disassembly, assembly and maintenance of the filter board assembly 3. On the other hand, it can avoid the problem of easily damaging the electronic components on the filter board assembly 3 during the installation of the screws, which can improve the production yield.

[0031] In some embodiments, the first clamping portion 21 is a buckle, and the second clamping portion 31 is a clamping hole, and the buckle and the clamping hole are detachably connected. With such a design, by pressing down the filter board assembly 3, the clamping hole on the filter board assembly 3 can be clamped to the buckle on the fan bracket 2, and the installation of the filter board assembly 3 on the fan bracket 2 can be realized, and the assembly and disassembly are simple and convenient. It can be understood that in other embodiments, according to actual use requirements, the design method of the first clamping portion 21 being a clamping hole and the second clamping portion 31 being a buckle can also be adopted, which is not limited here.

[0032] Further, there are multiple first clamping parts 21 and multiple second clamping parts 31, and multiple first clamping parts 21 are arranged at intervals on the fan bracket 2, and multiple second clamping parts 31 are arranged at intervals on the filter board assembly 3. The design mode of connecting multiple first clamping parts 21 and multiple second clamping parts 31 can improve the stability of the filter board assembly 3 installed on the fan bracket 2. Exemplarily, there are three first clamping parts 21 and three second clamping parts 31, and the three first clamping parts 21 are arranged in a triangle, and the second clamping parts 31 are arranged in a triangle.

[0033] In some embodiments, considering that many electronic components are arranged on the filter board assembly 3, in order to avoid the electronic components being squeezed and damaged by the fan bracket 2 if they are close to the fan bracket 2, a limiting structure 22 is further provided on the fan bracket 2. The limiting structure 22 is used to abut against the filter board assembly 3 to limit the installation position of the filter board assembly 3 on the fan bracket 2, ensuring that a safe distance is maintained between the filter board assembly 3 and the fan bracket 2, thereby protecting the electronic components on the filter board assembly 3.

[0034] Furthermore, the limiting structure 22 is a limiting rib extending in a direction toward the filter board assembly 3, and the first clamping portion 21 is provided at the end of the limiting rib. When the first clamping portion 21 is connected to the second clamping portion 31, the limiting rib abuts against the filter board assembly 3. With such a design, the first clamping portion 21 is provided on the limiting rib, which can simplify the structure of the fan bracket 2.

[0035] From the above, it can be seen that there are three first clamping parts 21, and correspondingly, there are also three limiting ribs, and the three first clamping parts 21 are respectively located on the three limiting ribs.

[0036] From the above, since the first clamping portion 21 is a buckle and the second clamping portion 31 is a bayonet, in order to avoid the limiting rib passing through the bayonet and failing to achieve the limiting effect, preferably, the outer diameter of the limiting rib is larger than the inner diameter of the bayonet.

[0037] In some embodiments, the fan assembly 1 is disposed at the lower part of the fan bracket 2, and the first clamping portion 21 is located at the upper part of the fan bracket 2, so that the filter board assembly 3 is installed at the upper part of the fan bracket 2. With such a design, the filter board assembly 3 and the fan assembly 1 are arranged in partitions, which can avoid mutual interference between the assembly and disassembly of the two, and can also make the entire fan filter board structure 50 more compact.

[0038] Furthermore, the filter plate assembly 3 is a plate-like structure. In order to facilitate the installation of the filter plate assembly 3 on the fan bracket 2, a horizontal mounting plate 23 is provided on the upper part of the fan bracket 2, and a plurality of first clamping portions 21 are spaced apart on the horizontal mounting plate 23, and a plurality of second clamping portions 31 are spaced apart on the plate-like filter plate assembly 3, so that the filter plate assembly 3 is installed in parallel on the horizontal mounting plate 23.

[0039] Furthermore, the fan assembly 1 includes a fan motor 11 and a fan blade 12, which are arranged on both sides of the lower part of the fan bracket 2, and the fan bracket 2 is provided with an avoidance groove 24, the fan motor 11 is fixed to the fan bracket 2, and the motor shaft of the fan motor 11 passes through the avoidance groove 24 and is connected to the fan blade 12, thereby realizing the installation and fixation of the fan motor 11 and the fan blade 12 on the fan bracket 2. With such a design, the structure of the fan filter plate structure 50 is more compact.

[0040] Furthermore, in order to realize the installation of the fan motor 11 on the fan bracket 2, a first mounting hole 111 is provided on the fan motor 11, and a second mounting hole 25 is provided on the fan bracket 2. The first mounting hole 111 and the second mounting hole 25 are connected by fasteners. The fasteners and mounting holes are used to realize the installation and fixation, and the structure is simple and the installation is convenient.

[0041] The utility model provides a microwave oven, which comprises a fan filter plate structure 50 including a fan assembly 1, a fan bracket 2 and a filter plate assembly 3. The fan assembly 1 is mounted on the fan bracket 2. The fan bracket 2 is provided with a first clamping portion 21. The filter plate assembly 3 is provided with a second clamping portion 31. The filter plate assembly 3 is detachably mounted on the fan bracket 2 through the matching connection between the second clamping portion 31 and the first clamping portion 21.
