Description

A fan lamp with open turbine blades Technical Field

[0001] The utility model relates to a fan lamp, in particular to a fan lamp with open turbine blades. Background Art

[0002] Fan lights can provide both ventilation and illumination, integrating ventilation and illumination into a multifunctional product. Compared to separate fan lights and lamps, they take up significantly less space, making them popular with consumers. To improve the aesthetics and safety of fan lights, bladeless fan lights have emerged. These blades are hidden within the housing and are therefore invisible to the user.

[0003] As a practitioner who has been engaged in the research and development of fan lamps for a long time, the inventor discovered during the development and testing of fan lamps that existing bladeless fan lamps have the following defects: a bloated structure, making it difficult to achieve an ultra-thin design; low air volume and high noise. The reason for this is due to the fan blade structure used. Specifically, the fan blades used in the existing bladeless fan lamps include a bottom plate, a top plate, and a center column connecting the top and bottom plates. The center column is provided with a number of blades. When the fan lamp is working, air can only be sucked in from the inner side of the fan blades. After being driven by the blades at high speed, it is thrown out from the outer side. In addition, such a fan blade structure leaves a large space around the blades, making it difficult to get close to the inner wall of the shell, resulting in turbulent air flow. Such a structure limits the air supply of the fan lamp, causing users to feel that the air volume is insufficient when exposed to the wind. In order to increase the air supply, the solution is to increase the height of the fan blades to increase the side space of the fan blades, thereby achieving the purpose of increasing the air intake and air supply; or to increase the speed of the fan blades. The result is: although the air supply volume is improved to a certain extent, the overall height of the fan light increases accordingly. As a result, the appearance of the fan light will become bloated, and it is difficult to achieve revolutionary improvement and optimization of the appearance. In addition, the high speed brings high noise, and the user experience is discounted.

[0004] For this reason, it is necessary to improve and optimize the existing bladeless fan lamp.

[0006] The utility model aims to solve at least one of the problems in the prior art. To this end, the utility model provides a fan lamp with open turbine blades, which has a simple structure, a large air flow and low noise.

[0007] The technical solution adopted by the utility model to solve its technical problems is:

[0008] A fan lamp with open turbine blades, comprising:

[0009] The housing is provided with an air inlet at the upper portion thereof and an air guide wall extending downward;

[0010] a motor disposed in the housing, the motor comprising a central shaft and a rotor, the rotor being rotatable relative to the central shaft, the central shaft being connected to the housing;

[0011] The fan blade is a turbine-type fan blade connected and fixed to the rotor, and includes a base plate and blades arranged above the base plate. The blades are arched and multiple, and there is no top plate above the blades to form an open structure. The top of the blades is arranged opposite to the inner wall of the housing;

[0012] A lighting assembly includes a chassis and a light-transmitting panel disposed on the chassis, wherein the chassis is disposed below the fan blades; in a radial direction, a gap is formed between the lighting assembly and the air guide wall, wherein the gap forms an air supply gap;

[0013] When the fan lamp is in the air supply working state, the motor drives the fan blades to rotate, and the fan blades rotate toward the side where the blades are arched.

[0014] Optionally, the side end and the upper end of the blade are arranged close to the inner wall of the shell, wherein the side end of the blade is ≤7mm away from the wind guide wall; the upper end of the blade is ≤7mm away from the inner top wall of the shell.

[0015] Optionally, the bottom plate of the fan blade is a flat plate, or the bottom plate of the fan blade is an upwardly convex arc plate; the chassis is correspondingly configured as a flat plate or an arc plate.

[0016] Optionally, an air guide plate is provided on the inner wall of the shell, and there are one or more air guide plates, which divide the air supply gap into several air supply areas.

[0017] Optionally, a slot is provided on the chassis, and the air guide plate is inserted into the slot.

[0018] Optionally, the lighting assembly further comprises a dough ring, which is sleeved on the periphery of the chassis and the light-transmitting panel, and the light-transmitting panel is fixed to the chassis via the dough ring; there is a gap between the dough ring and the air guide wall of the shell to form an air supply gap.

[0019] Optionally, the chassis is fixed on the central axis.

[0020] Optionally, a receiving cavity is provided on the shell above the fan blades, and an atmosphere light source is provided in the receiving cavity.

[0021] Optionally, an air inlet grille is further provided on the shell, and the air inlet grille is installed on the shell from bottom to top.

[0022] Optionally, the fan lamp is a ceiling lamp, a makeup mirror lamp, a floor lamp or a chandelier.

[0023] The utility model has at least one of the following beneficial effects: the utility model embodiment is configured to have fan blades including a bottom plate and blades arranged above the bottom plate, the blades are arched and multiple, there is no top plate above the blades to form an open structure, and the top of the blades is arranged opposite to the inner wall of the shell; in the radial direction, there is a gap between the lighting component and the wind guide wall, and the gap forms an air supply gap. When the fan light is in the air supply working state, the motor drives the fan blades to rotate, and the fan blades rotate toward the side where the blades are arched. The air between the fan blade bottom plate and the inner top wall of the shell is radially thrown out under the drive of the arched blades. As a result, a vacuum zone is formed between the bottom plate and the inner top wall of the shell. The outside air flows into the air inlet and enters between the fan blade bottom plate and the inner top wall of the shell under the action of the pressure difference. The thrown air is squeezed into the air supply under the action of the shell guide wall. The air flows into the air gap and is eventually blown out from the air supply gap to form a wind flow. In particular, the fan blades have no top plate, so that the upper part of the blades is directly opposite to the inner wall of the shell, and the air is more easily driven by the blades and thrown out. Compared with the fan lamp in the prior art, the structure described in the embodiment of the utility model is easier to take in air, which means it has a larger air intake volume. Combined with the narrow air supply gap, it can produce a larger air supply volume. Since the fan blades are an open structure without a top plate, on the one hand, there is no top plate to occupy the height space inside the fan lamp, and on the other hand, the fan blades can be set flatter, so that the overall height of the fan lamp is reduced, which is beneficial to the ultra-thin design of the fan lamp. Due to the larger air intake and air supply volume, the speed requirement of the motor is reduced, and the noise of the fan lamp during operation is controlled and optimized, which is beneficial to improving the user experience.

DETAILED DESCRIPTION

[0044] To make the purpose, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless there is any conflict, the embodiments and features in the embodiments described below can be combined with each other in any manner.

[0045] Many different implementations or examples are provided below to implement the structure of the present invention.

[0046] Referring to Figures 1 to 11, a fan lamp with open turbine blades according to an embodiment of the present invention comprises: a shell 1, which is generally made of plastic parts. An air inlet 11 is provided on the upper part of the shell 1, and an air guide wall 12 extending downward is provided on the shell 1. The air guide wall 12 extends downward so that the air supply gap formed in the end can face the user, so as to facilitate the user to receive the wind. It can be understood that the so-called downward extension is obtained by observing at the angle shown in Figures 1 and 1.1. In actual use, the air guide wall 12 can be extended horizontally so that the air supply gap can face the user, such as a floor fan lamp; a motor 2, which is arranged in the shell 1, and the motor 2 has a central axis 21 and a rotor 22. The rotor 22 is rotatable relative to the central axis 21. The motor 2 is an outer rotor motor, and the central axis 21 is rotatable. The shaft 21 is connected to the housing 1, and the connection can be a direct connection or an indirect connection through other components so that the two are relatively fixed; the fan blade 3 is a turbine-type fan blade, which is connected and fixed to the rotor 22. The fan blade 3 moves in conjunction with the rotor 22. The fan blade 3 includes a bottom plate 31 and blades 32 arranged above the bottom plate 31. The blades 32 are arched and there are multiple blades. There is no top plate above the blades 32 to form an open structure. The top of the blades 32 is arranged opposite to the inner wall of the housing 1, that is, a wind cavity is formed between the blades 32 and the inner wall of the housing 1. It can be understood that, when projected in the axial direction of the central axis 21, the blades 32 can completely overlap with the inner wall of the housing 1, or they can partially overlap. As shown in this embodiment, a portion of the blades 32 is exposed and visible in the air inlet grille;

[0047] The lighting assembly 4 includes a chassis 41 and a light-transmitting panel 42 mounted on the chassis 41. The chassis 41 is positioned below the fan blades 3. In the radial direction, the lighting assembly is spaced apart from the air guide wall 12, forming an air supply gap 5. The light-transmitting panel 42 may be a light guide plate, such as the fan light with a light guide plate structure shown in FIG1.1, or a lampshade, such as the lampshade shown in FIG11. The installation of the light guide plate, lampshade, and related light-emitting unit is well known in the art and will not be further described here.

[0048] When the fan lamp is in the air supply working state, the motor drives the fan blades to rotate, and the fan blades rotate toward the side where the blades are arched. Taking the ceiling lamp shown in Figure 1 and Figure 1.1 as an example, observing the fan blades from the ceiling toward the bottom, the positive projection shown in Figure 4.2 is obtained, and the rotation direction of the fan blades 3 is counterclockwise. It can be understood that if the blades are arched in the opposite direction, the fan blades rotate in a clockwise direction. It can be understood that under the structure shown in Figure 1 and Figure 1.1, the fan blades 3 rotate counterclockwise to the air supply state. Under the same rotation speed, the wind force is strong and the noise is small; according to the program setting, the fan blades 3 can also rotate clockwise (that is, rotate toward the concave side of the blades). At this time, the fan lamp has weak wind force and loud noise under the same rotation speed of the fan blades. This function is no longer a normal air supply function, but a circulating fan function that drives the flow of indoor air.

[0049] Specifically referring to Figure 1.1 , in some embodiments of the present invention, the side and upper ends of the blades 32 are disposed proximate to the inner wall of the housing 1 , wherein the side ends of the blades 32 are ≤7 mm from the air guide wall 12 ; and the upper ends of the blades 32 are ≤7 mm from the inner top wall of the housing 1 . This structure maximizes the radial and axial dimensions of the blades, allowing them to move more air, thereby increasing airflow. Furthermore, the height space between adjacent blades is closer to a closed state, making it easier to form a negative pressure, allowing outside air to be drawn in and then ejected along the air duct formed between the adjacent blades.

[0050] Specifically referring to FIG10 , in some embodiments of the present invention, the bottom plate 31 of the fan blade 3 is a flat plate; specifically referring to FIG1.1 and FIG4.3 , the bottom plate 31 of the fan blade 3 is a convex curved plate, and the chassis 41 is correspondingly configured as a flat plate or a curved plate. Configuring the bottom plate 31 of the fan blade as a convex curved plate provides a certain wind-guiding effect, allowing the wind ejected between adjacent blades 32 to more easily form an obtuse angle with the wind-guiding wall 12 rather than a right angle, thereby reducing wind loss and increasing air delivery.

[0051] Specifically referring to Figures 1.1, 2, 5, and 6.1, in some embodiments of the present invention, an air deflector 13 is provided on the inner wall of the housing 1. One or more air deflectors 13 are provided. These air deflectors 13 divide the air supply slit 5 into several air supply areas, making the air output of the fan light more uniform. Furthermore, this prevents the interaction of high-speed air with the blades, which can cause wind force cancellation, thereby increasing the air supply volume. In this embodiment, the spacing between the side ends of the blades 32 and the air deflectors 13 is controlled to be ≤7 mm.

[0052] In order to improve the structural strength of the air deflector 13 and facilitate accurate installation of the chassis 41 , in some embodiments of the present invention, a slot 43 is provided on the chassis 41 , and the air deflector 13 is inserted into the slot 43 .

[0053] With specific reference to Figures 1.1, 2, 8, and 8.1, in some embodiments of the present invention, the lighting assembly 4 further comprises a dough ring 44, which is sleeved around the periphery of the chassis 41 and the light-transmitting panel 42. The light-transmitting panel 42 is secured to the chassis 41 via the dough ring 44. A gap is formed between the dough ring 44 and the air guide wall 12 of the housing 1 to form an air supply gap 5. The dough ring 44 can be secured to the chassis 41 via an undercut 45. The dough ring 44 forms a component of the air supply gap 5, making the exposed side of the air supply gap 5 neat and aesthetically pleasing.

[0054] Specifically referring to FIG. 1.1 , in some embodiments of the present invention, in order to simplify the connection, fixation and installation structure of the lighting assembly 4, the chassis 41 is fixed on the central axis 21, and the central axis 21 of the motor 2 is used to suspend the lighting assembly 4, which is reliable in structure and simple to assemble.

[0055] Specifically referring to FIG1.1, in some embodiments of the present invention, a receiving cavity 14 is provided on the housing 1 above the fan blades 3, and an ambient light source (not shown in the drawing, but may be an LED light strip) is provided in the receiving cavity 14. Taking the ceiling lamp shown in FIG1.1 as an example, when the user needs to take a break, if the lighting component 4 serving as the main light is turned on, the light from the lighting component 4 directly enters the human eye, and even if the light of the lighting component 4 is dimmed, it will give the user a sense of discomfort. The light emitted by the ambient light source in the receiving cavity 14 first shines on the ceiling, and then enters the human eye after diffuse reflection from the ceiling, making the light softer and more comfortable.

[0056] Specifically referring to Figures 1.1 and 9 , in some embodiments of the present invention, the housing 1 is further provided with an air intake grille 6, which is mounted on the housing 1 from bottom to top. Compared to the prior art structure in which the air intake grille is mounted on the housing 1 from top to bottom, the assembly method of this embodiment not only avoids the exposure of assembly screws, but also allows the air intake grille 6 to be integrally formed, thereby improving assembly efficiency.

[0057] The fan lamp shown in the embodiment of the present invention has a wide range of uses, and can specifically be a ceiling lamp, a makeup mirror lamp, a floor lamp, or a chandelier, etc.

[0058] Specifically refer to FIG1.1, where the dotted arrows indicate a schematic diagram of the air inlet and air supply circuit. As can be seen from the above structural analysis, the embodiment of the utility model is configured such that the fan blade 3 includes a bottom plate 31 and a plurality of blades 32 arranged above the bottom plate 31. The blades 32 are arched and are provided in a plurality of shapes. There is no top plate above the blades 32, forming an open structure, and the top of the blades 32 is arranged opposite to the inner wall of the shell 1; in the radial direction, there is a gap between the lighting component 4 and the wind guide wall 12, and the gap forms an air supply gap 5. When the fan light is in the air supply working state, the motor drives the fan blades to rotate, and the fan blades rotate toward the side of the blade arch. The air between the fan blade bottom plate 31 and the inner top wall of the shell 1 is driven by the arched blades and is thrown radially outward. As a result, a vacuum zone is formed between the bottom plate 31 and the inner top wall of the shell 1. The outside air flows into the air inlet 11 under the action of the pressure difference and enters between the fan blade bottom plate 31 and the inner top wall of the shell 1. The thrown air is squeezed into the air supply gap 5 under the action of the shell guide wall 12, and is finally blown out from the air supply gap 5 to form wind The fan blades have no top plate, so that the upper part of the blades is directly opposite to the inner wall of the shell, and the air is more easily driven by the blades and thrown out. Compared with the fan lamp in the prior art, the structure described in the embodiment of the utility model is easier to take in air, which means it has a larger air intake volume. Combined with the narrow air supply gap, it can produce a larger air supply volume; since the fan blades are an open structure without a top plate, on the one hand, there is no top plate to occupy the height space inside the fan lamp, and on the other hand, the fan blades can be set flatter, so that the overall height of the fan lamp is reduced, which is beneficial to the ultra-thin design of the fan lamp. Due to the larger air intake and air supply volume, the speed requirement of the motor is reduced, and the noise of the fan lamp during operation is controlled and optimized, which is beneficial to improving the user experience.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
