Description
Technical Field

[0002] Ceiling-mounted or recessed air conditioners, also known as ceiling-mounted units, are installed within the ceiling, saving indoor space. Compared to other types of air conditioners, they are not only space-saving but also aesthetically pleasing, combining comfort and decoration, making them ideal for homes and offices. Ceiling-mounted air conditioners are gaining popularity among users.
[0003] like Figure 1 As shown, the ceiling fan 12 typically has loads 7 such as water pumps and electronic expansion valves arranged on the positive pressure side (the side where the evaporator 6 is located). These loads 7 need to be connected to electronic components on the main board inside the electrical box 2 via wires. The electrical box 2 is generally located on the negative pressure side. Although there is a partition (fan plate 3) between the positive and negative pressure sides, the presence of the wiring hole 4 will create a positive and negative pressure connection structure. This means that cold air from the positive pressure zone will be introduced into the negative pressure zone and may mix with humid air. Ultimately, under cooling conditions, condensation may occur on the wiring from the positive pressure zone to the negative pressure zone through the wiring hole 4, and humid air may enter the electrical box 2 through the wiring hole 4 to form condensation, threatening the reliability of the ceiling fan 12.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0036] See Figures 2-6 The present invention provides a flow guiding structure, including a flow guiding body 1, which is disposed between an electrical box 2 and a fan plate 3, for separating the wire passage hole 4 on the electrical box 2 from the wire passage hole 4 on the fan plate 3, so as to prevent the air on the positive pressure side from flowing directly into the wire passage hole 4 on the electrical box 2 from coming out of the wire passage hole 4 on the fan plate 3.
[0037] This airflow guiding structure directs the wiring through the wire hole 4 on the fan plate 3 to the wire hole on the electrical box 2. At the same time, it utilizes the high airflow velocity on the side of the ceiling fan 5 to guide the airflow by means of the velocity difference. The airflow field of the fan 5 carries away some of the cold air flowing to the side of the electrical box 2 through the wire hole 4 on the fan plate 3, thereby reducing the amount of cold air entering the electrical box 2 and preventing cold air from directly flowing into the interior of the electrical box 2 and forming condensation.
[0038] In this embodiment, the flow guide body 1 can be installed on the electrical box 2, or on the fan plate 3, or simultaneously on both the electrical box 2 and the fan plate 3, to prevent straight-line communication between the wire hole 4 on the electrical box 2 and the wire hole 4 on the fan plate 3.
[0039] In this illustrative embodiment, the flow guide body 1 is provided with a wire hole and a wire cavity communicating with the wire hole. The wire hole is positioned near the air inlet of the fan 5. The wire cavity can be connected to the wire passage hole 4 on the electrical box 2. The wire passing through the fan plate 3 can go around the flow guide body 1 to the wire hole and enter the wire cavity through the wire hole to enter the electrical box 2 through the wire passage hole 4 on the electrical box 2. Alternatively, the wire cavity can be connected to the wire passage hole 4 on the fan plate 3. The wire passing through the fan plate 3 can enter the wire cavity and pass through the wire hole to the outside of the wire cavity to enter the electrical box 2 through the wire passage hole 4 on the electrical box 2.
[0040] like Figure 2 As shown, in a specific implementation of one embodiment of the present invention, the guide body 1 has a concave structure with an opening, and the internal space of the guide body 1 forms a wire cavity 8. A wire through hole is provided on the side wall of the guide body 1 near the fan 5. The opening of the guide body 1 is connected to the electrical box 2 so that the wire cavity 8 is connected to the wire through hole 4 on the electrical box 2 (e.g., Figure 4 (as shown), or, as Figure 3As shown, the opening of the guide body 1 is connected to the fan plate 3 so that the wire cavity 8 is connected to the wire hole 4 on the fan plate 3.
[0041] In an optional embodiment of the present invention, the cross-sectional shape of the flow guiding structure in the direction parallel to the axis of the wire hole 4 on the fan plate 3 is a horizontally arranged U-shape. The flow guiding body 1 is mounted on the electrical box 2 by a fixed connection or a movable connection. Of course, the flow guiding body 1 can also be mounted on the fan plate 3 by a fixed connection or a movable connection.
[0042] To facilitate the disassembly and replacement of the flow guide structure, preferably, the flow guide structure and the electrical box 2 or the flow guide structure and the fan plate 3 are connected by a sliding connection. Specifically, a slide rail 9 can be provided on the electrical box 2 or the fan plate 3, and the flow guide body 1 is slidably connected to the slide rail 9. The connection method is simple.
[0043] In another specific implementation of the present invention, combined with Figure 5 and Figure 6 The flow guide body 1 includes an electrical box connection part 10 and a fan plate connection part 11, both of which are plate-shaped structures. The electrical box connection part 10 and the fan plate connection part 11 are connected and form a wire cavity between them. The electrical box connection part 10 is connected to the electrical box 2, and the fan plate connection part 11 is connected to the fan plate 3. The electrical box connection part 10 and the fan plate connection part 11 are disposed between the wire passage hole 4 on the electrical box 2 and the wire passage hole 4 on the fan plate 3 to separate the two wire passage holes 4.
[0044] In order to better separate the wire hole 4 on the electrical box 2 from the wire hole 4 on the fan plate 3, the electrical box connecting part 10 is located above the wire hole 4 on the electrical box 2, and the fan plate connecting part 11 is located below the wire hole 4 on the fan plate 3. The wire cavity is connected to the wire hole 4 on the electrical box 2. The wires passing through the fan plate 3 can go around the wire hole along the fan plate connecting part 11 and can enter the wire cavity between the electrical box connecting part 10 and the fan plate connecting part 11 through the wire hole to enter the electrical box 2 through the wire hole 4 on the electrical box 2.
[0045] Alternatively, the electrical box connection part 10 is located below the wire hole 4 on the electrical box 2, and the fan plate connection part 11 is located above the wire hole 4 on the fan plate 3. The wire cavity is connected to the wire hole 4 on the fan plate 3. The wires passing through the fan plate 3 can enter the wire cavity and pass through the wire hole to the outside of the wire cavity, and then enter the wire hole 4 on the electrical box 2 along the connection plate of the electrical box 2.
[0046] In this embodiment, the electrical box connecting part 10 is fixedly or movably connected to the electrical box 2, and the fan plate connecting part 11 is fixedly or movably connected to the fan plate 3. Typically, the electrical box connecting part 10 and the electrical box 2, and the fan plate connecting part 11 and the fan plate 3, are configured with the same connection method. To facilitate the disassembly and replacement of the flow guiding structure, preferably, the flow guiding structure and the electrical box 2, as well as the flow guiding structure and the fan plate 3, are both configured with sliding connections. Specifically, slide rails 9 are provided on both the electrical box 2 and the fan plate 3. The electrical box connecting part 10 is slidably connected to the slide rail 9 of the electrical box 2, and the fan plate connecting part 11 is slidably connected to the slide rail 9 of the fan plate 3.
[0047] As an optional implementation, the electrical box connection part 10 and the fan plate connection part 11 are configured as an integrally formed structure, which is structurally stable and easy to process, and forms a "V"-shaped structure between the electrical box connection part 10 and the fan plate connection part 11. Of course, the specific shape of the air guiding structure is not limited here, the purpose is to separate the wire passage hole 4 on the electrical box 2 from the wire passage hole 4 on the fan plate 3, so as to prevent the air on the positive pressure side from flowing directly into the wire passage hole 4 on the electrical box 2 from coming out of the wire passage hole 4 on the fan plate 3. At the same time, part of the cold air flowing to the electrical box 2 side through the wire passage hole 4 on the fan plate 3 will be guided to the air inlet of the fan 5. Taking advantage of the high airflow velocity on the fan 5 side of the ceiling fan, the airflow is guided by the velocity difference. The flow field of the fan 5 carries away part of the cold air flowing to the electrical box 2 side through the wire passage hole 4 on the fan plate 3, thereby reducing the amount of cold air entering the electrical box 2.
[0048] The wires coming out through the wire hole 4 on the fan plate 3 must be deflected by the aforementioned flow guiding structure before entering the electrical box 2. Assuming the air velocity in the fan 5 flow field is V1 and the velocity of the cold air flow is V2, the velocity of V1 is actually much greater than V2. By utilizing the velocity difference between the fluids, the cold air flowing out from the positive pressure side through the wire hole 4 on the fan plate 3 is easily carried away by the fan 5 flow field, thus preventing condensation inside the electrical box 2.
[0049] According to another aspect of the present invention, a ceiling fan is provided, including the above-described flow guiding structure. In this embodiment, the ceiling fan includes a fan plate 3 and an electrical box 2, wherein the axis of the wiring hole on the fan plate 3 is collinear with the axis of the wiring hole on the electrical box 2, or the wiring hole on the fan plate 3 and the wiring hole on the electrical box 2 are misaligned.
[0050] The wiring holes 4 of the fan board 3 and the electrical box 2 are designed to be staggered vertically, which is more suitable for use. Figure 3The flow guide structure shown allows the wires leading out through the wire holes 4 on the fan plate 3 to pass through the flow guide structure more easily, then bend back, and finally enter the electrical box 2 along the flow guide structure. This way, even if cold air is not carried away by the fan 5 and condensation forms, it is not easy for the folded wires to enter the electrical box 2. Since the electrical box connection part 10 and the fan plate connection part 11 are both plate-shaped structures, when the wires bend along the electrical box connection part 10 or / and the fan plate connection part 11, the condensation on the wires will flow down and drip, further achieving the effect of preventing condensation inside the electrical box 2.
[0051] In addition, a humidity detection structure, which is a humidity-detecting resistor, is installed inside the electrical box 2 to detect the humidity inside the electrical box 2. By detecting the humidity inside the electrical box 2, a series of controls can be implemented on the unit. This includes controlling the compressor frequency, the speed of the internal fan 5, and the opening of the air guide vane to enhance the function of the airflow guiding device and improve the anti-condensation effect of the electrical box 2. Condensation is most likely to occur in the indoor unit under conditions of low speed, low output, and small air guide vane opening.
[0052] Furthermore, the present invention also provides an air conditioning device, including the aforementioned ceiling-mounted unit. This air conditioning device also has the aforementioned beneficial effects.
[0053] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
