Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic transformer installation, and more specifically, to a microwave oven electronic transformer installation structure and a microwave oven. Background Technology
[0002] An electronic transformer is an important component in a microwave oven. It converts low voltage into high voltage, thus enabling food to be heated quickly.
[0003] However, currently, electronic transformers are generally installed directly on the protective casing. This method is relatively simple, and people can easily disassemble the electronic transformer during self-repair. Therefore, a microwave oven that can reinforce the electronic transformer substrate and prevent non-professionals from performing self-repair, thus ensuring safe use, is what is currently needed.
[0004] Therefore, it is necessary to propose a microwave oven electronic transformer installation structure and a microwave oven that can solve the above problems. Utility Model Content
[0005] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a microwave oven electronic transformer mounting structure and a microwave oven.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a microwave oven electronic transformer mounting structure for mounting an electronic transformer substrate, including a first mounting shell and a second mounting shell;
[0007] The first mounting housing has a mounting buckle on one side and a guide mounting protrusion on the other side. The second mounting housing has a buckle block on one side and a mounting clip block on the other side. The first mounting housing is connected to the buckle block of the second mounting housing through the mounting buckle. The guide mounting protrusion of the first mounting housing is connected to the mounting clip block of the second mounting housing.
[0008] The four corners of the electronic transformer substrate are respectively fixed between the first mounting housing and the second mounting housing. The bottom of the electronic transformer substrate is provided with a protrusion, which is engaged between the guide mounting protrusion and the mounting block.
[0009] A wire channel for wire entry is provided between the first mounting housing and the second mounting housing. The mounting buckle and buckle block facilitate the fixation of the first mounting housing and the second mounting housing. The guide mounting groove and mounting clip block provide a stronger connection to the electronic transformer substrate during installation, and can also be directly fixed to the microwave oven, thus facilitating installation. In practical applications, the installation between the guide mounting groove and the mounting clip block can be fixed with screws with unique bayonet joints, thus avoiding self-repair by non-professionals.
[0010] Furthermore, the outer side of the guide mounting protrusion is provided with a limiting inner groove, which facilitates the clamping and fixing of the guide mounting protrusion.
[0011] Furthermore, the electronic transformer substrate is provided with a heat sink, and the first mounting housing is provided with heat dissipation ducts. The heat dissipation ducts are connected to the heat sink, and the heat dissipation ducts provided on the first mounting housing can facilitate heat dissipation of the heat sink.
[0012] Furthermore, a through slot is provided on the electronic transformer substrate on one side of the heat sink, and a heat-conducting groove connected to the through slot is provided in the second mounting housing. By providing a through slot on the electronic transformer substrate and a heat-conducting groove connected to the through slot in the second mounting housing, heat can be dissipated on both sides simultaneously when the heat sink dissipates heat, thereby accelerating the heat dissipation speed.
[0013] Furthermore, both the first mounting housing and the second mounting housing are provided with mounting holes, which facilitate the installation and fixation of the first mounting housing, the electronic transformer substrate, and the second mounting housing.
[0014] Furthermore, both the first mounting housing and the second mounting housing are made of plastic material. In practical applications, the first mounting housing and the second mounting housing can also be made of other materials, all of which are within the protection scope of this utility model.
[0015] This utility model also discloses a microwave oven with an electronic transformer mounting structure, including a microwave oven body, wherein the electronic transformer mounting structure is disposed within the microwave oven body.
[0016] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0017] The microwave oven electronic transformer mounting structure disclosed in this utility model facilitates the fixing of the first mounting shell and the second mounting shell through the setting of mounting buckles and buckle blocks. Furthermore, through the setting of guide mounting protrusions and mounting clips, the microwave oven electronic transformer mounting structure can further strengthen the connection with the electronic transformer base plate during installation, and can also be directly fixed to the microwave oven, thereby facilitating installation.

[0026] like Figure 1As shown, a microwave oven electronic transformer mounting structure is used to mount an electronic transformer substrate 1, including a first mounting housing 2 and a second mounting housing 3; the first mounting housing 2 has a mounting buckle 4 on one side and a guide mounting groove 5 on the other side; the second mounting housing 3 has a buckle block 6 on one side and a mounting latch block 7 on the other side; the first mounting housing 2 is connected to the buckle block 6 of the second mounting housing 3 through the mounting buckle 4, and the guide mounting groove 5 of the first mounting housing 2 is connected to the mounting latch block 7 of the second mounting housing 3; the four corners of the electronic transformer substrate 1 are respectively fixed between the first mounting housing 2 and the second mounting housing 3, and the bottom of the electronic transformer substrate 1 is provided with a protrusion 8. The protrusion 8 is engaged between the guide mounting protrusion 5 and the mounting block 7; a wire channel 9 for wire entry is provided between the first mounting housing 2 and the second mounting housing 3. The mounting buckle 4 and the buckle block 6 facilitate the fixation of the first mounting housing 2 and the second mounting housing 3. With the guide mounting protrusion 5 and the mounting block 7, the microwave oven electronic transformer mounting structure can be further strengthened to the electronic transformer base plate 1 during installation, and can also be directly fixed to the microwave oven, thus facilitating installation. In practical applications, the installation between the guide mounting protrusion and the mounting block can be fixed with screws with unique bayonet joints, thus avoiding self-repair by non-professionals.
[0027] like Figure 2-3 As shown, the guide mounting protrusion 5 is provided with a limiting inner groove 9 on its outer side. The limiting inner groove 9 can facilitate the clamping and fixing of the guide mounting protrusion 5. The electronic transformer base plate 1 is provided with a heat sink 10, and the first mounting housing 2 is provided with a heat dissipation duct 11. The heat dissipation duct 11 is connected to the heat sink 10. The heat dissipation duct 11 provided on the first mounting housing 2 can facilitate the heat dissipation of the heat sink 10.
[0028] like Figure 4-5 As shown, a through groove 12 is provided on the electronic transformer substrate 1 on one side of the heat sink 10, and a heat-conducting groove 13 connected to the through groove 12 is provided in the second mounting housing 3. By providing a through groove 12 on the electronic transformer substrate 1 and a heat-conducting groove 13 connected to the through groove 12 in the second mounting housing 2, heat dissipation can be carried out on both sides of the heat sink 10 at the same time when it dissipates heat, thus accelerating the heat dissipation speed. Mounting holes 14 are provided on both the first mounting housing 2 and the second mounting housing 3. The mounting holes 14 facilitate the installation and fixation between the first mounting housing 2, the electronic transformer substrate 1 and the second mounting housing 3.

[0030] Example
[0031] In this embodiment, the first mounting housing and the second mounting housing are respectively secured to both sides of the electronic transformer substrate. The tops of the first and second mounting housings are fastened using conventional methods such as mounting buckles and fasteners, while the bottoms of the first and second mounting housings are fixed using guide mounting protrusions and mounting clips. Since protrusions are provided on the electronic transformer substrate and are located between the guide mounting protrusions and mounting clips, and the installation between the guide mounting protrusions and mounting clips can be fixed using screws with unique bayonet joints, and since the fixing is directly locked to the microwave oven, even if non-professionals can open the mounting buckles and fasteners, they cannot remove the electronic transformer substrate without damaging the first and second mounting housings, thus avoiding unauthorized repairs by non-professionals. Of course, in practical applications, an integrated stop block can also be provided on the microwave oven shell above the first and second mounting housings to prevent the tops of the first and second mounting housings from being opened.
