Abstract
Description
A microwave oven electronic transformer mounted on a substrate Technical Field
[0001] This utility model relates to the field of spare parts installation, and more specifically, to a mounting base plate for an electronic transformer used in a microwave oven. Background Technology
[0002] Currently, microwave ovens are widely used because they can quickly heat food. The electronic transformer used in microwave ovens is an essential part of them, and it can greatly shorten the cooking time.
[0003] Most electronic transformers are typically installed directly in a sealed, insulated structure through through-holes. However, this can be difficult in confined spaces. Furthermore, if an electronic transformer is installed in a poorly ventilated cavity, it may experience heat conduction difficulties.
[0004] Therefore, it is necessary to propose a mounting substrate for an electronic transformer used in microwave ovens to solve the above problems. Summary of the Invention
[0005] To overcome at least one of the defects (deficiencies) of the prior art described above, this utility model provides a mounting substrate for an electronic transformer used in microwave ovens.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: an electronic transformer mounting base for microwave ovens, used to support the electronic transformer base, including a mounting base body and a limiting strip disposed on the mounting base body;
[0007] The limiting strip is hollow and is connected to the heat dissipation groove on the electronic transformer substrate.
[0008] The limiting clip is provided with a connecting mounting bracket, and the bottom of the electronic transformer substrate is provided with a mounting groove. The electronic transformer substrate is fitted onto the connecting mounting bracket of the limiting clip through the mounting groove. By setting the limiting clip to a hollow shape and connecting the limiting clip to the heat dissipation groove on the electronic transformer substrate, heat dissipation is facilitated. Compared with the traditional installation method, this utility model provides a mounting groove at the bottom of the electronic transformer substrate. During installation, the electronic transformer substrate only needs to be fitted onto the connecting mounting bracket of the limiting clip through the mounting groove to achieve installation, which facilitates installation in narrow spaces.
[0009] Furthermore, the connecting mounting bracket is provided with heat dissipation through holes, which facilitates heat dissipation at the connection between the connecting mounting bracket and the mounting groove.
[0010] Furthermore, it also includes support bars. The connecting mounting bracket is connected to the limiting strip via support bars. By setting support bars, a gap can be created between the connecting mounting bracket and the limiting strip, which facilitates heat dissipation. At the same time, support bars of different heights can be used during production as needed, thus facilitating use in different application scenarios.
[0011] Furthermore, reinforcing ribs are provided between adjacent support bars to enhance the connection strength between the support bars.
[0012] Furthermore, the connecting mounting bracket is equipped with a limiting block, which can limit the installation of the electronic transformer substrate.
[0013] Furthermore, the mounting base body is provided with support feet, which facilitates the fixing and installation of the mounting base body.
[0014] Furthermore, the mounting base plate body is provided with heat dissipation holes, which facilitate heat dissipation of the mounting base plate body.
[0015] Compared with the prior art, the beneficial effects of this utility model's technical solution are:
[0016] The microwave oven electronic transformer with mounting base disclosed in this utility model has a hollow limiting strip that is connected to the heat dissipation groove on the electronic transformer base plate, which facilitates heat dissipation. Compared with the traditional installation method, this utility model has a mounting groove at the bottom of the electronic transformer base plate. During installation, the electronic transformer base plate can be installed simply by fitting it into the connecting mounting bracket of the limiting strip through the mounting groove, which is convenient for installation in narrow spaces.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0025] As shown in Figures 1-5, an electronic transformer mounting base for microwave ovens supports an electronic transformer base 1. The base includes a mounting base body 2 and a limiting strip 3 mounted on the mounting base body 2. The limiting strip 3 is hollow and connected to a heat dissipation groove 4 on the electronic transformer base 1. A connecting mounting bracket 5 is provided on the limiting strip 3, and a mounting groove 6 is provided at the bottom of the electronic transformer base 1. The electronic transformer base 1 is mounted on the connecting mounting bracket 5 of the limiting strip 3 through the mounting groove 6. By making the limiting strip 3 hollow and connecting it to the heat dissipation groove 4 on the electronic transformer base 1, heat dissipation is facilitated. Compared to traditional installation methods, this invention, by providing a mounting groove 6 at the bottom of the electronic transformer base 1, allows for easy installation by simply mounting the electronic transformer base 1 onto the connecting mounting bracket 5 of the limiting strip 3 through the mounting groove 6, thus facilitating installation in confined spaces.
[0026] In this utility model, a heat dissipation through hole 7 is provided on the connecting mounting bracket 5. The heat dissipation through hole 7 facilitates heat dissipation at the connection between the connecting mounting bracket 5 and the mounting groove 6. In addition, a support bar 8 is also included. The connecting mounting bracket 5 is connected to the limiting clip 3 through the support bar 8. The support bar 8 allows for a gap between the connecting mounting bracket 5 and the limiting clip 3, which facilitates heat dissipation. At the same time, support bars 8 of different heights can be used during production as needed, thus facilitating use in different application scenarios. A reinforcing rib 9 is provided between adjacent support bars 8. The reinforcing rib 9 strengthens the connection strength between the support bars 8. Furthermore, a limiting block 10 is provided on the connecting mounting bracket 5. The limiting block 10 limits the installation of the electronic transformer substrate 1.
[0027] In this utility model, a support foot 11 is provided on the mounting base body 2. The support foot 11 facilitates the fixing and installation of the mounting base body 2. The mounting base body 2 is provided with heat dissipation holes 12 to facilitate heat dissipation of the mounting base body 2.
