Description

Technical Field

[0001] This utility model relates to a household appliance flow guiding device, and in particular to a retractable and adjustable smoke guide. Background Technology

[0002] Currently, the sizes of existing range hoods on the market vary, making it difficult to match various sizes of cooktops. There's a specific distance between each side of the range hood and the cooktop for optimal performance. However, currently, a single range hood size is often designed for a single cooktop size. This forces manufacturers to produce range hoods in multiple sizes to accommodate different cooktop dimensions. Furthermore, existing machines can only be used on relatively flat surfaces. While the two side air ducts of the integrated design can be folded up, the two middle air ducts cannot be folded up or disassembled, causing inconvenience in storage and increasing production, packaging, and transportation costs. Moreover, existing range hoods are directly plugged in without power storage, requiring a cord connection, which is extremely inconvenient. Some range hoods also use metal cross-flow impellers, which undoubtedly increases the difficulty of cleaning.

[0003] In summary, existing air guide fans suffer from drawbacks such as poor compatibility, high production difficulty and cost, inconvenience in use, transportation difficulties, poor flexibility in use, and difficulty in cleaning. These drawbacks severely limit their further promotion and application in this field.

[0004] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

This detachable connection method enables the connection of the power control module 1, the first retractable flow guiding module 21, the second retractable flow guiding module 22, the third retractable flow guiding module 23, and the fourth retractable flow guiding module 24. This not only reduces production difficulty and costs but also effectively improves production efficiency, flexibility, and versatility. Furthermore, disassembly and transportation are possible during transport, reducing transportation difficulty and costs, facilitating wider application, and enhancing market competitiveness.

[0054] The air duct 200 includes a large air duct 260 and a small air duct 270. The small air duct 270 is retractably disposed inside the large air duct 260 and together with the large air duct 260 forms a retractable air duct.

The first damping limiting piece 281 and the second damping limiting piece 282 match each other and are used to restrict the small air guide duct 270 from being pulled out of the large air guide duct 260. Additionally, the large air duct 260 has a first fixing hole, and the first damping limiting piece 281 has a first protrusion 2811 that is pressed into the first fixing hole to fix the first damping limiting piece 281 onto the large air duct 260. The small air duct 270 has a second fixing hole, and the second damping limiting piece 282 has a second protrusion 2821 that is pressed into the second fixing hole to fix the second damping limiting piece 282 onto the large air duct 270.

The upper part of the large air duct 260 and the small air duct 260 is provided with an air outlet 201 that is slit-shaped and runs through the front and back. The air outlet 201 on the large air duct 260 and the air outlet 201 on the small air duct 270 are interconnected and partially overlap. The bottom of the large air duct 260 and the small air duct 270 are provided with a recessed wire mounting groove 202. The wire mounting groove 202 is used for the wires inside the case module to prevent the wires from affecting the airflow and blocking the air outlet 201.

[0058] Specifically, in this embodiment, the power control module 1, the first retractable flow guiding module 21, and the second retractable flow guiding module 22 are horizontally distributed and sequentially detachably connected, while the third retractable flow guiding module 23 and the fourth retractable flow guiding module 24 are vertically arranged, and the third retractable flow guiding module 23 and the fourth retractable flow guiding module 24 are perpendicular to the power control module 1, the first retractable flow guiding module 21, and the second retractable flow guiding module 22.

[0059] In some embodiments, the implementer may also select one or more of the current guiding modules to connect and use with the power control module 1 as needed. For example, refer to Figure 11 , Figure 11 The illustration shows the application state after the first retractable flow guiding module 21 is disassembled and the second retractable flow guiding module 22 is directly connected to the power control module 1. It has the characteristics of high application flexibility, which can improve the user experience and can match and adapt to different usage environments.

The power control module 1, the first retractable current guiding module 21, the second retractable current guiding module 22, the third retractable current guiding module 23, and the fourth retractable current guiding module 24 are electrically connected via an electrical connection assembly. The detachable connection device enables the power control module 1, the first retractable current guiding module 21, the second retractable current guiding module 22, the third retractable current guiding module 23, and the fourth retractable current guiding module 24 to be electrically connected. The detachable connection function allows for simultaneous connection of the power control module 1, the first retractable current guiding module 21, the second retractable current guiding module 22, the third retractable current guiding module 23, and the fourth retractable current guiding module 24 via an electrical connection component after they are connected through the detachable connection device. In this way, the rechargeable battery in the power control module 1 can provide power to the first retractable current guiding module 21, the second retractable current guiding module 22, the third retractable current guiding module 23, and the fourth retractable current guiding module 24.

Then, the air inside the first retractable air guiding module 21, the second retractable air guiding module 22, the third retractable air guiding module 23, and the fourth retractable air guiding module 24 is blown out through the air outlet 201. The blown airflow forms an air curtain barrier, isolating harmful air such as smoke inside the air curtain. The air inside the air curtain can only be sucked away by the matching smoke extractor 6, ensuring fresh and safe air.
