Description

Technical Field

[0001] This utility model belongs to the field of ventilation equipment technology, and more specifically, it relates to a duct fan. Background Technology

[0002] Roof ducted fans are essential ventilation devices in daily life. Existing roof ducted fans typically have a metal roof panel installed at the top to prevent rainwater from entering the room, and an axial flow fan is installed on the underside of the metal hood to ventilate the room. However, due to the large overall size of the axial flow fan, it suffers from problems such as being too tall, too thick, and too large after installation. Therefore, this paper studies and improves upon the existing structure and its shortcomings to provide a ducted fan with greater practical value. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a duct fan, which is achieved by the following specific technical means:

[0004] A duct fan includes a top plate, a mounting base fixedly installed on the bottom side of the top plate, and a fan connected to the bottom side of the mounting base; an air inlet is provided at the center of the bottom side of the fan, and a connection port for connecting to a duct is provided on the outer side near the air inlet; the fan includes an upper shell and a lower shell, and a centrifugal fan is installed between the lower shell and the upper shell; the air inlet is located at the center of the bottom end of the lower shell and communicates with the centrifugal fan.

[0005] Furthermore, solar panels are fixedly embedded in the top of the roof panel.

[0006] Furthermore, an exhaust vent is provided at the connection between the lower and upper housings.

[0007] Furthermore, there are two sets of connection ports, both of which are concentrically positioned with the air inlet.

[0008] Furthermore, the solar panels are electrically connected to the centrifugal fan via a controller.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This utility model utilizes a centrifugal fan, which rotates centrifugally and discharges air from all four directions to achieve a larger air volume. It also solves the problems of existing axial fans being too tall, too thick, and too large. This fan can effectively reduce indoor temperature, provide a fresh and pleasant air environment, and its simple and beautiful design can be integrated into various architectural styles, becoming a beautiful feature on the roof. It combines the three major advantages of environmental protection, energy saving, and high efficiency, avoids stuffiness, and effectively prevents wind and rain backflow, bringing users a comfortable experience like a "fresh air system".

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Example 1, as shown in the attached document Figure 1 To be continued Figure 4 As shown:

[0022] This utility model provides a duct fan, including a top plate 1, a fixing seat 3 fixedly installed on the bottom side of the top plate 1, and a fan 2 connected to the bottom side of the fixing seat 3; an air inlet is provided at the center of the bottom side of the fan 2, and a connection port 204 for connecting to a duct is provided on the outer side near the air inlet; the fan 2 includes an upper shell 201 and a lower shell 203, and a centrifugal fan 202 is installed between the lower shell 203 and the upper shell 201. By using a centrifugal fan 202, the overall volume can be effectively reduced, effectively solving the problems of being too tall, too thick, and too large in size of other existing fans; the air inlet is located at the center of the bottom end of the lower shell 203 and is connected to the centrifugal fan 202.

[0023] An exhaust vent is provided at the connection between the lower housing 203 and the upper housing 201 to facilitate rapid and smooth ventilation.

[0024] The connection port 204 is provided in two sets, both of which are concentric with the air inlet. The inner diameters of the two sets of connection ports 204 are 110mm and 160mm respectively, which is suitable for places that require ventilation by connecting pipes with a diameter of 110mm or 160mm. It provides a flexible and diverse ventilation solution for various buildings and has good adaptability.

[0025] Example 2 differs from Example 1 in that:

[0026] like Figure 5 As shown, a solar panel 4 is fixedly embedded in the top of the top plate 1. The solar panel 4 is electrically connected to the centrifugal fan 202 through a controller. By fixing the solar panel 4 in the top of the top plate 1, solar energy can be used as a power source to convert solar energy into electrical energy to drive the fan 2 to rotate the fan blades, so as to achieve smooth air circulation between indoors and outdoors, effectively reduce indoor temperature, and achieve the characteristics of green energy saving and environmental protection during use.

[0027] When in use, the roof panel 1 with or without solar panels 4 can be selected according to the actual usage scenario. When the roof panel 1 without solar panels 4 is installed, it can be connected to the mains power using wires. When the roof panel 1 with solar panels 4 is installed, solar energy can be used as a power source. The solar energy is converted into electrical energy through the solar panels 4 to drive the fan 2 to rotate the fan blades, so as to achieve smooth air circulation between indoors and outdoors. It can effectively reduce indoor temperature without relying on traditional electricity. Therefore, it is green, energy-saving and environmentally friendly during use, especially under sufficient sunlight, the ventilation effect is particularly significant.

[0028] This fan not only effectively reduces indoor temperature and provides a fresh and pleasant air environment, but also blends into various architectural styles with its simple and beautiful design, becoming a beautiful feature on the roof. It combines the three major advantages of environmental protection, energy saving, and high efficiency, avoiding stuffiness and effectively preventing backflow of wind and rain, bringing users a comfortable experience like a "fresh air system". At the same time, it adopts a centrifugal fan 202, which rotates centrifugally and discharges air in four directions to achieve a larger air volume, and can also solve the problems of existing fans being too tall, too thick, and too large.

[0029] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
