Summary of the Invention
Problems to be Solved by the Invention
[0005] However, considering safety and the like, it is preferable to provide a blade guard on the rear side as well. However, if a blade guard is provided, it becomes impossible to easily clean the rear side of the blower blades. Although it is possible to clean by removing the front guard and the blower blades, it is preferable to be able to easily clean the rear side of the blower blades where dust easily adheres.
[0006] This invention was made in view of the above circumstances, and its objective is to provide a blower with a lighting function that allows for easy cleaning of the rear side of the blower blades. [Means for solving the problem]
[0007] To solve the above problems, the blower with lighting function according to the present invention Blower and A ring-shaped lighting unit is positioned around the blower, A fan support section for supporting the fan in the lighting section, A mounting part that is attached to the part to be mounted and connected to the lighting part, A connecting part that connects the mounting part and the lighting part, It comprises a front guard that protects the front of the blower and a rear guard that protects the rear of the blower, A part of the rear guard is detachably attached.
[0008] The operation and effects of a fan with lighting function based on this configuration will be explained. This device is equipped with a front guard that protects the front of the fan and a rear guard that protects the rear. The rear guard is not entirely removable, but a part of it is detachable. By removing this part, a portion of the rear of the fan blades is exposed, allowing dust removal work to be performed while the blades are rotating. It is not necessary to remove the entire fan blades. As a result, the rear of the fan blades can be easily cleaned.
[0009] In this invention, it is preferable that a portion of the rear guard is formed in a fan shape when viewed from above. This allows a portion of the rear guard to be detachable while maintaining the overall design of the rear guard.
[0010] The blower according to the present invention is pivotally supported by the blower support so as to be rotatable around a horizontal axis relative to the lighting unit, and it is preferable that the rear guard and the shaft having the horizontal axis are integrally formed.
[0011] By integrally forming the rear guard and the shaft, the number of parts can be reduced and assembly can be made easier.
[0012] In this invention, it is preferable that the connecting portion extends in the same horizontal direction as the shaft portion. This prevents the connecting portion from getting in the way when attaching or detaching a part of the rear guard, making attachment and detachment easier.
[0013] In this invention, it is preferable that the rear surface of the rear guard is located in front of the rear surface of the lighting unit.
[0014] With this configuration, the blower can rotate around the blower support without interfering with other components. [Brief explanation of the drawing]

[0016] A preferred embodiment of the blower with lighting function according to the present invention (hereinafter simply referred to as the blower) will be described with reference to the drawings. Figure 1 is an external perspective view of the blower as seen from below. Figure 2 is a front view of the blower. Figure 3 is a side view of the blower. Figure 4 is an external perspective view of the blower as seen from the rear.
[0017] The air blower device includes a lighting unit 1 and a blower 2. The lighting unit 1 is formed in a ring shape and includes a support body 10 and a ring-shaped cover 11. Inside the lighting unit 1, there are an LED substrate 12 and a number of LED elements 13 mounted on this LED substrate 12 (see FIGS. 5 and 6). The support body 10 and the ring-shaped cover 11 are joined by an appropriate method (such as screws, adhesion, press-fit, etc.).
[0018] Although the specific shape of the LED substrate 12 is not shown in the drawings, a plurality of LED substrates 12 can be arranged side by side in a ring shape. The ring-shaped cover 11 is made of a resin with light transmissivity and irradiates the illumination light emitted by the LED elements 13 downward. The air blower device is attached to the ceiling (corresponding to the attachment part). In particular, it is used in places where lighting and ventilation are required, such as bathrooms and toilets, but as the present invention, it is not limited to specific usage locations.
[0019] As shown in the cross-sectional views of FIGS. 5 and 6, the blower 2 has a cylindrical central part 20, blower blades 21, and a shaft fitting part 22 integrally formed. Seven blower blades 21 are provided around the central part 20. The number and shape of the blower blades 21 can be determined appropriately. In addition, a front guard 30 and a rear guard 31 are provided in front of and behind the blower blades 21 so as not to directly touch the blower blades 21. A number of openings are formed in the front guard 30 and the rear guard 31. The front guard 30 and the rear guard 31 are joined by the combination of the groove 30c formed in the front guard 30 and the boss 31c formed in the rear guard 31 (see FIG. 5).
[0020] As shown in FIG. 6, the frontmost surface 30a of the blower 2 is positioned lower than the frontmost surface 11a of the lighting unit 1. The blower 2 is provided with a motor 5, and the blower blades 21 are fixed to the motor shaft 5a fixed to the motor 5 by a well-known method. If the front guard 30 is removed, the entire blower blades 21 can be removed.
[0021] The blower 2 is supported with respect to the lighting unit 1 by a bearing 15 and a collar 17 (these correspond to a blower support portion) (see FIG. 5). As shown in FIG. 5, a pair of bearings 15 and collars 17 are provided on the left and right. The bearing 15 sets a horizontal axis, and the posture of the blower 2 can be inclined around this axis. Thereby, the blowing direction of the blower 2 can be inclined. FIG. 7 is a perspective view showing the state where the blower 2 is inclined.
[0022] The bearing 15 has a through hole 15a formed therein, and wiring can be passed through here. Thereby, power can be supplied to the motor 5 that drives the blower blades 21. The collar 17 is formed in a cylindrical shape and is fitted on the outer periphery of the bearing 15.
[0023] The mounting portion 4 extends in the vertical direction and includes a support column portion 40, a base 41, and a connecting shaft 42. The support column portion 40 has a cylindrical shape, and a power supply circuit, a control circuit, etc. (not shown) are mounted in the internal space. The base 41 is attached to a socket (attached portion) (not shown) provided on the ceiling. In this embodiment, a connection method by a socket and a base is described, but other attachment methods may be adopted and it is not limited to a specific connection method.
[0024] The mounting portion 4 is connected to the connecting portion 14. The connecting portion 14 is integrally formed with the support main body 10, but may be constituted by a separate member from the support main body 10. The connecting portion 14 is arranged in the direction along the axis of the blower 2. As shown in FIG. 7, when the blower 2 is rotated around the axis, it is possible to avoid interference with the connecting portion 14 and secure the maximum possible rotation angle.
[0025] A connecting member 16 is provided in the center of the connecting section 14, and a spherical section 16a is provided at its upper part. By fitting the inner surface of the connecting shaft 42 into this spherical section 16a, the entire blower 2 and lighting section 1 can be moved in the direction of arrow C in Figure 6. This allows the overall posture (tilt angle) of the blower 2 and lighting section 1 to be adjusted. For example, any angle between ±150° can be set, and the blower 2 and lighting section 1 can be adjusted to direct the airflow towards people in the room.
[0026] The inside of the connecting member 16 is hollow, allowing wiring to pass through. This enables power to be supplied to the lighting unit 1 and the blower 2.
[0027] As shown in Figure 8, the fan-shaped guard 32, which is part of the rear guard 31, can be removed. The fan-shaped guard 32 is formed in a fan shape in plan view, and its central angle is 60°. The central angle can be determined as appropriate, taking into consideration ease of cleaning, etc. The fan-shaped guard 32 is fixed to the rear guard 31 by screws 33. Screw holes 34 are formed in the rear guard 31. By removing the fan-shaped guard 32, the rear side of the blower blades 21 is exposed, allowing for the removal of dust and other debris adhering to the rear side. Although only a portion of the blower blades 21 is exposed, the entire rear side can be cleaned by rotating the blower blades 21 by hand while cleaning. The fan-shaped guard 32 does not have to be exactly the same shape as a fan in a mathematical sense, but may be a similar shape. It is not limited to a specific shape.
[0028] The blower according to this invention is installed to blow air downwards, so dust tends to accumulate more easily on the rear side of the blower blades 21 than on the front side. Therefore, the frequency of cleaning the rear side increases. By removing a part of the rear guard 31 as described above, cleaning can be performed efficiently without having to remove the entire blower blades 21. In addition, the position of the screw 33 is such that it does not interfere with the connecting part 14 in a plan view, so the fan-shaped guard 32 can be easily attached and detached.
[0029] As shown in Figures 5 and 7, a shaft portion 35 is integrally formed with the rear guard 31. The shaft portion 35 is a hollow cylindrical shape, with bearings 15 fitted to both ends. This allows the blower 2 to be rotatably supported around its axis. As also shown in Figure 8, the shaft portion 35 is located directly below the connecting portion 14 and extends in the same direction. As shown in Figure 6, the rear surface 31a of the rear guard 31 is lower than the rear surface 10a of the support body 10 of the lighting unit 1. Also, as shown in Figure 5, an appropriate gap is formed between the outer circumferential surface 31b of the rear guard 31 and the inner wall surface 11b of the ring-shaped cover 11 of the lighting unit 1. This prevents obstruction when the blower 2 rotates around its axis.
[0030] As shown in Figure 5, a cover 18 is provided on the lower surface of the connecting portion 14, and the inside of the connecting portion 14 is hollow. Wiring from the power supply circuit etc. provided in the mounting portion 4 is supplied to the LED board 12 of the lighting portion 1 via the connecting member 16 and through the inside of the connecting portion 14. Furthermore, the wiring is also connected to the blower 2 via the hole 15a of the bearing 15 and through the inside of the shaft portion 35.
[0031] <How to use> A brief explanation of how to use the blower device according to this invention will be provided. The blower device itself can be installed by inserting the nozzle 41 into a socket set on the ceiling. The tilt direction of the blower 2 can be set by manually moving the blower 2 itself and rotating it around its axis (bearing 15). The tilt direction including the lighting unit 1 and the blower 2 can also be set in direction C as shown in Figure 6.
[0032] The operation of the blower can be controlled via a remote control. This allows for switching the blower 2 on and off, adjusting the rotation speed of the blower blades 21, setting the forward and reverse rotation of the blower blades 21, and switching the color temperature of the lighting unit 1. As mentioned above, cleaning of the blower blades 21 can be done by removing the fan-shaped guard 32 to clean the rear of the blower blades 21. Additionally, the entire blower blade 21 can be cleaned by removing the front guard 30.
[0033] The blower with lighting function according to the present invention can be used as a pure lighting device when the blower is not used, and can be used as a pure blower when the lighting unit is not used. [Explanation of Symbols]
