Abstract
Description
Technical Field
[0001] The utility model relates to the field of waveguides, and particularly relates to a waveguide. Background Technique
[0002] A waveguide is a device used to guide the propagation of electromagnetic waves and is widely used in fields such as wireless communication, radar, and microwave ovens. Its basic structure is a metal pipe with a specific shape, usually rectangular or circular. The working principle of the waveguide is to reflect and transmit electromagnetic waves inside it, enabling the electromagnetic waves to propagate along the direction of the pipe. Its design is usually based on a specific working frequency range to ensure effective transmission and minimum energy loss.
[0003] The key features of the waveguide include high-efficiency power transmission ability and low-loss characteristics. Compared with traditional cables, the waveguide can better maintain signal quality in high-frequency applications. Due to the precise control of its size and shape, the waveguide can effectively suppress signal attenuation and interference in high-frequency signal transmission. In addition, the material of the waveguide is generally selected as a metal with good conductivity, such as copper or aluminum, to ensure the best electromagnetic wave conduction effect. Although the waveguide is relatively bulky and inflexible in low-frequency applications, in microwave and higher-frequency applications, the waveguide is still an ideal choice for transmitting and processing electromagnetic signals.
[0004] Currently, for the waveguide box of microwave oven products, since the waveguide box needs to be welded to the cavity, according to the latest UL standard and the requirement of cavity concealment, the test rod cannot reach deep into the cavity. Therefore, most of them solve the concealment problem by plugging holes on the outer shell, bottom plate or rear plate. However, such a method has a great impact on the heat dissipation of the product. For this reason, a waveguide is proposed to solve the above problems. Content of the Utility Model

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figures 1 - 4 As shown in the figure, an embodiment provided by the present utility model: A waveguide includes a cavity component 1. The cavity component 1 is an internal part of a microwave oven, commonly used for heating food. A lid 2 is fixedly connected to the outside of the cavity component 1. The lid 2 is used to connect the waveguide box 3 to the cavity component 1. A waveguide box 3 is fixedly connected to the outside of the lid 2. The waveguide box 3 is used to receive and transmit electromagnetic wave signals. A stirring motor bracket 4 is fixedly connected to the top of the waveguide box 3. A stirring motor baffle 5 is fixedly connected to the left side of the stirring motor bracket 4. The stirring motor bracket 4 is used to connect and fix the stirring motor to keep the stirring motor stable. The stirring motor baffle 5 is to block the welding process hole 7, playing a role of concealment and not affecting heat dissipation. A magnetron bracket 6 is fixedly connected to the left side of the waveguide box 3. The magnetron bracket 6 is used to connect an installation seat of the magnetron. A welding process hole 7 is provided inside the waveguide box 3. The welding process hole 7 is for a test rod to extend into the inside of the waveguide box 3 for testing. A plurality of welding points 8 are provided on the outside of the lid 2 and the outside of the waveguide box 3. The cavity component 1 and the waveguide box 3 are fixedly connected by welding through the welding points 8. The welding process hole 7 is provided directly below the stirring motor baffle 5 to block the welding process hole 7. The waveguide box 3 is in an "L" shape to better fit the cavity component 1. The lid 2 and the waveguide box 3 are fixedly connected by welding through the welding points 8. The lid 2 and the cavity component 1 are fixedly connected by welding through the welding points 8. The waveguide box 3 and the stirring motor bracket 4 are fixedly connected by welding through the welding points 8. The waveguide box 3 and the magnetron bracket 6 are fixedly connected by welding through the welding points 8. The welding points 8 are used to weld and fix each part to form a whole.
[0031] Working principle: During welding and installation, first weld the lid 2 and the waveguide box 3 through the solder joints 8, then weld the lid 2 to the cavity assembly 1 through the solder joints 8. Next, weld the magnetron bracket 6 to the left side of the waveguide box 3. Then, weld the stirrer motor bracket 4 with the stirrer motor baffle 5 to the top of the waveguide box 3 through the solder joints 8, and make the stirrer motor baffle 5 cover the welding process hole 7. The stirrer motor baffle 5 and the welding process hole 7 are not completely fitted, and the stirrer motor baffle 5 is "Z" - shaped when viewed from the side. This will create a gap between the process hole and the baffle, which can be used for heat dissipation. While hiding the hole, it will not affect heat dissipation.
[0032] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
