Description

Technical Field

[0001] The present invention relates to the field of fan technology, and particularly to a ceiling fan.

Background Art

[0002] In the operation process of a central air-conditioning system, its air outlet or the equipment itself usually needs to be equipped with a fan to enhance the diffusion effect of the air flow, avoid the indoor air supply dead zone or the cold / hot air layer separation phenomenon, and thereby ensure the temperature uniformity.

[0003] However, there are defects in such existing fan designs: the blades disperse the air flow at the air outlet of the air conditioner and disrupt the original air circulation path, resulting in a decrease in the suction efficiency of the central suction port of the central air conditioner. As a result, the air-conditioning system has to increase the operating power to maintain the suction volume, directly causing an increase in energy consumption. On the other hand, since the air supply diffusion range of such a fan is limited, when used in a large indoor space, the indoor temperature distribution is likely to be uneven.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Embodiments of the present invention provide a ceiling fan to solve the problems of the prior art that the energy consumption of the central air conditioner increases due to the change of the air circulation path and the indoor temperature distribution becomes uneven.

Means for Solving the Problems

[0005] The ceiling fan according to the present invention is a mounting base, and The present invention provides a ceiling fan comprising several blades spaced apart and surrounding the outside of a mounting base, wherein each blade includes an airflow diffusion member and an airflow guide member, the airflow diffusion member being integrally connected to the airflow guide member and located on the side of the airflow guide member away from the mounting base, the intake side of the airflow diffusion member being located on the upper part of the blade, and the discharge side of the airflow guide member being located on the upper part of the blade, wherein the airflow diffusion member includes a blade on which an airflow guide curve is formed.

[0006] In one embodiment, the airflow guide surface includes a first surface and a second surface, the second surface being located between the first surface and the airflow guide member, and the first surface being bent and connected to the second surface.

[0007] In one embodiment, the second curved surface is positioned at an angle to the direction of gravity, and the first curved surface is positioned extending toward the upper part of the blade in a direction away from the second curved surface.

[0008] In one embodiment, the airflow guide surface further includes a third surface, the third surface being helical and located between the second surface and the airflow guide member.

[0009] In one embodiment, the airflow guide member is installed at an angle to the direction of gravity.

[0010] In one embodiment, several ventilation holes are installed through the connection between the airflow diffusion member and the airflow guide member, and these ventilation holes are spaced apart in the width direction of the blade.

[0011] In one embodiment, the blade further includes a fixed base, the fixed base being installed on the side closer to the mounting base of the airflow guide member, and the ceiling fan further includes several fan rods, the several fan rods each having one end connected to the mounting base and the other end connected to the fixed base of the several blades, respectively.

[0012] In one embodiment, a slot is provided in the fixed base, and the other end of the fan rod is inserted into the slot.

[0013] In one embodiment, the blade further includes a reinforcing rod, one end of which is connected to the fixed base and the other end which extends toward the airflow diffusion member and is connected to the airflow diffusion member and the airflow guide member.

[0014] In one embodiment, several relief grooves are provided on the reinforcing rod, and several of the relief grooves are arranged at intervals in the direction of extension of the reinforcing rod. [Effects of the Invention]

[0015] The beneficial effects of the ceiling fan according to the embodiment of this invention are as follows:

[0016] This ceiling fan not only enhances indoor airflow and allows the air conditioning system to operate efficiently with low power consumption, but it can also expand the airflow coverage area and ensure a more uniform temperature throughout the room.

[0017] Specifically, in the first embodiment, the airflow diffusion member of the blade corresponds to the outlet of the central air conditioner, and the airflow guide member of the blade corresponds to the central intake of the central air conditioner. When the airflow from the air conditioner outlet acts on the airflow diffusion member, several blades are driven and rotated in sync, diffusing the airflow outward while distributing it radially in the mounting base. At the same time, the airflow guide member guides the air from below upward to the air conditioner's intake as the blades rotate, thereby forming an air circulation path. This reduces the number of times the central air conditioner is forced to increase its output due to insufficient intake, and significantly reduces the system's energy consumption.

[0018] In the second aspect, the airflow guide surface formed by the airflow diffusion member guides and controls the airflow at the air outlet in terms of direction, ensuring efficient rotation of the blade driven by the airflow. At the same time, by optimizing the curvature of the surface, the airflow is diffused along a preset trajectory, further expanding the range of the indoor air supply cover and improving the uniformity of the temperature in the space.

Modes for Carrying Out the Invention

[0020] It should be noted that, as long as there is no contradiction, the embodiments and the features in the embodiments in the present application can be combined with each other. The preferred embodiments of the present invention will be described in detail below by combining the drawings.

[0021] The sealing fan 1000 according to an embodiment of the present invention is applied to the central air conditioner 2000. As shown in FIGS. 1 to 2, the sealing fan 1000 includes a mounting base 10 and several blades 20. The several blades 20 are spaced apart and arranged to surround the outside of the mounting base 10. The blade 20 includes an air flow diffusion member 21 and an air flow guide member 22. The air flow diffusion member 21 is integrally connected to the air flow guide member 22 and is located on the side of the air flow guide member 22 away from the mounting base 10. The suction side of the air flow diffusion member 21 is located at the upper part of the blade 20, and the blowing side of the air flow guide member 22 is located at the upper part of the blade 20. Here, an air flow guide curved surface 211 is formed on the air flow diffusion member 21. The sealing fan 1000 of the present application can solve the problems of the prior art that the energy consumption of the central air conditioner 2000 increases due to the change of the air circulation path and the indoor temperature distribution becomes uneven. The sealing fan 1000 can not only strengthen the flow of indoor air and make the air conditioner system operate efficiently with low power, but also expand the air supply cover range to ensure the uniformity of indoor temperature.

[0022] Specifically, in the first aspect, the air flow diffusion member 21 of the blade 20 corresponds to the air outlet 210 of the central air conditioner 2000, and the air flow guide member 22 of the blade 20 corresponds to the central suction port 220 of the central air conditioner 2000. When the air flow at the air outlet 210 of the air conditioner acts on the air flow diffusion member 21, several blades 20 are synchronously driven to rotate, and while dispersing the air flow in the radial direction of the mounting base 10 and diffusing it outward, the air flow guide member 22 guides the air below upward to the suction port of the air conditioner as the blade 20 rotates, thereby forming an air circulation path and reducing the case where the central air conditioner 2000 forcibly increases the output due to insufficient suction, and greatly reducing the energy consumption of the system.

[0023] In the second embodiment, the airflow guide curved surface 211 formed by the airflow diffusion member 21 guides and controls the airflow from the outlet 210 in a directional manner, ensuring the efficient rotation of the blade 20 by driving the airflow. At the same time, by optimizing the curvature of the curved surface, the airflow is diffused along a preset trajectory, further expanding the range of airflow coverage in the room and improving the uniformity of the temperature in the space.

[0024] Furthermore, in this application, since the airflow diffusion member 21 is integrally connected to the airflow guide member 22 in the blade 20, the assembly steps can be reduced and the installation efficiency of the ceiling fan 1000 can be greatly improved.

[0025] Referring to Figures 3 to 5, in one embodiment, the airflow guide curved surface 211 includes a first curved surface 211 and a second curved surface 2112, the second curved surface 2112 is located between the first curved surface 2111 and the airflow guide member 22, and the first curved surface 2111 is bent and connected to the second curved surface 2112. By installing it in this manner, the first curved surface 2111 and the second curved surface 2112 can increase the contact area with the airflow, and when the airflow contacts the first curved surface 2111 and the second curved surface 2112, a portion of the airflow directly pushes the blade 20 to rotate, improving the rotational efficiency of the blade 20, and the other portion of the airflow is divided into two airflow channels and diffused outward by the curved guide, thereby expanding the airflow coverage area of ​​the ceiling fan 1000 and optimizing the airflow path.

[0026] Preferably, the second curved surface 2112 is installed at an angle to the direction of gravity (shown as U in Figure 4), and the first curved surface 2111 is installed extending toward the upper part of the blade 20 in a direction away from the second curved surface 2112. In this way, since the airflow direction from the outlet 210 of the central air conditioner 2000 is usually directed diagonally downward, by installing the second curved surface 2112 at an angle to the direction of gravity, when the airflow comes into contact with the second curved surface 2112, the second curved surface 2112 can change the direction of the airflow, a portion of the airflow can push and move the second curved surface 2112, and the other portion of the airflow may be guided downward by the second curved surface 2112. Furthermore, in the rotation process of the blade 20, the first curved surface 2111 is directed toward the second curved surface 2112. Therefore, the guided downward airflow can be further divided into two airflow channels, and the air can be divided into two more airflow channels again, diffusing outwards to expand the coverage area. The other airflow channel flows upward along the first curved surface 2111, reducing the dead zone for airflow. This not only allows for precise control of the airflow of the central air conditioner 2000 and improves the power efficiency of the blades 20, but also optimizes the airflow path through multi-stage diversion, ultimately achieving the effect of expanding the coverage area and reducing wasted airflow, further improving the uniformity of indoor air circulation.

[0027] Specifically, the second curved surface 2112 is positioned at an angle of 50° or more and 70° or less with respect to the direction of gravity. Exemplarily, in this embodiment, the angle between the second curved surface 2112 and the direction of gravity is set to 60°.

[0028] In one embodiment, the airflow guide surface 211 further includes a third surface 2113, which is helical and located between the second surface 2112 and the airflow guide member 22. By installing it in this manner, the helical third surface 2113 guides the airflow it contacts to flow gradually along the helical path to the second surface 2112 and the first surface 2111, and in combination with the first surface 2111 and the second surface 2112, completes the outward diffusion and upper circulation airflow paths, minimizing airflow loss and further expanding the coverage area.

[0029] Referring to Figure 4, in one embodiment, the airflow guide member 22 is installed at an angle (shown in Figure 4) to the direction of gravity. By installing it in this manner, the airflow guide member 22 is advantageous in facilitating the intake of the central air conditioner 2000 by forming an upward airflow from the air below during the rotation process and guiding this airflow to the intake port 220. Furthermore, because the airflow guide member 22 is adjacent to the intake port 220 and is installed extending upward toward the intake port 220, the airflow path can be shortened.

[0030] Specifically, the airflow guide member 22 is installed so as to form an angle of 20° or more and 40° or less with respect to the direction of gravity. Exemplarily, in this embodiment, the angle between the airflow guide member 22 and the direction of gravity is set to 25°.

[0031] Referring to Figures 3 to 5, in one embodiment, several ventilation holes 23 are installed through the connection between the airflow diffusion member 21 and the airflow guide member 22, and the ventilation holes 23 are spaced apart in the width direction of the blade 20. By installing them in this way, as the airflow guide member 22 rotates, it forms an airflow from the air below and guides it upward, causing the airflow to flow into the intake port 220 through the ventilation holes 23, increasing the amount of intake air for the central air conditioner 2000, avoiding the airflow guide member 22 and the airflow diffusion member 21 from forming a barrier to the airflow, and further optimizing the air circulation path.

[0032] Referring to Figures 1 to 5, in one embodiment, the blade 20 further includes a fixed base 24, which is installed on the side of the airflow guide member 22 closer to the mounting base 10, and the ceiling fan 1000 further includes several fan rods 30, each having one end connected to the mounting base 10 and the other end connected to the fixed base 24 of the blades 20, respectively. By installing them in this manner, the fan rods 30 extend the distance between the blades 20 and the mounting base 10, aligning the airflow guide member 22 and the airflow diffusion member 21 to positions corresponding to the central air conditioner 20000, expanding the operating coverage area of ​​the ceiling fan 1000 and enhancing the cooling effect. By installing the fixed base 24 on the blades 20, the stability of the connection with the fan rods 30 is improved, ensuring that neither shakes or loosens during the operating process, improving the overall stability of the ceiling fan 1000 and favoring the promotion of air circulation flow.

[0033] In one embodiment, a slot 241 is installed in the fixed base 24, and the other end of the fan rod 30 is inserted into the slot 241. By installing it in this way, the installation of the slot 241 ensures the stability of the connection with the fan rod 30, while also making the mounting method of both quicker and more efficient.

[0034] Referring to Figures 3 to 5, in one embodiment, the blade 20 further includes a reinforcing rod 25, one end of which is connected to a fixed base 24, and the other end which extends toward the airflow diffusion member 21 and is connected to the airflow diffusion member 21 and the airflow guide member 22. By installing it in this manner, the reinforcing rod 25 increases the structural strength of the blade 20, avoids vibration of the blade 20 due to centrifugal force during high-speed rotation, and thereby ensures the stability of the airflow guide path and the safety of its operation.

[0035] In one embodiment, the reinforcing rod 25 is provided with several relief grooves 251, which are spaced apart in the direction of extension of the reinforcing rod 25. By installing them in this manner, the relief grooves 251 reduce the weight of the reinforcing rod 25, thereby reducing the overall weight of the blade 20. This ensures the structural strength of the blade 20 itself while simultaneously making the blade 20 lighter, which is advantageous for the rotation of the blade 20 by airflow.
