Description
Waterproof fan
[0001] The present invention relates to an electric fan that provides a blowing function, and more specifically, the present invention relates to a waterproof electric fan that applies a waterproof structure to an electric device in a structure that rotates blades using electric power to generate blowing air, so that it can be easily washed with water to remove contamination during use without having to disassemble for cleaning, has a rechargeable battery so that the fan can be used wirelessly or the blades can be rotated for washing to maximize the cleaning effect, and uses an anti-static material so that contamination can be minimized.
[0002] In general, a fan can generate airflow by means of rotational power. By connecting a motor and blades and supplying power to the motor, the blades rotate by the rotational power of the motor, and airflow can be generated.
[0003] However, since it has an open structure for ventilation, contamination may occur due to the inflow of dust and foreign substances when used for a long period of time.
[0004] When contamination occurs, the blade and cover must be separated and washed individually to prevent electrical device failure.
[0005] And when disassembling for cleaning, it is firmly fixed for safe use, so it becomes difficult for the elderly, women, or children to disassemble it.
[0006] In addition, in order to use it safely in a separated state, all moisture must be removed, dried, and then combined before use, which causes a problem in that it cannot be used while washing and drying are taking place.
[0007] Previously introduced fans only had waterproof batteries, but the electrical components were not waterproof, so liquids could flow into the electrical components, and thus, if contamination occurs, the electrical components must be separated and cleaned, which is a problem.
[0008] Additionally, if the parts are combined and used without being completely dry, liquid may enter the electrical device, causing the electrical device to malfunction.
[0009] The present invention aims to provide a waterproof fan that uses electric power to rotate blades to generate airflow, applies a waterproof structure to an electric device, and allows easy washing with water to remove contamination during use without the need to disassemble for washing, has a rechargeable battery to enable wireless use of the fan or to perform washing with water while rotating the blades to maximize the washing effect, and uses an anti-static material to minimize contamination.
[0010] In addition, the purpose is to provide a waterproof fan that can be easily detached and attached to the head using a waterproof terminal, making it easy to separate for storage, and can be easily reassembled and used by reattaching the waterproof terminal when reusing.
[0011] In order to solve the above problem, the present invention can provide a waterproof fan characterized by including a waterproof head part that provides a blowing function; a stand provided at the lower part of the waterproof head part to support the waterproof head part; and a waterproof control part that is connected to the waterproof head part and controls the operation of the waterproof head part.
[0012] In addition, the waterproof head part may include an antistatic blade that provides a blowing function by rotation, an antistatic housing that is provided on the outside of the antistatic blade to protect the antistatic blade and form a space where blowing air is generated, a safety cover that is provided on both sides of the antistatic housing to form an inlet and outlet path for blowing air and prevent contact with the antistatic blade, a BLDC motor that is connected to the antistatic blade to provide power to rotate the antistatic blade, and a motor molding that is provided to surround the outside of the BLDC motor.
[0013] In addition, the motor molding may have a retainer oil seal installed on the outside of the rotational axis of the BLDC motor connected to the anti-static blade.
[0014] Here, a power cable for supplying power to the BLDC motor side is installed at the bottom of the motor molding, and a cable cover may be provided on the outside of the power cable to prevent liquid from flowing into the power cable side.
[0015] In this case, the safety cover may be coated with anti-static powder on the mesh structure.
[0016] In addition, the safety cover may be made of an anti-static resin material.
[0017] Additionally, the stand may include a vertical support extending to the lower portion of the waterproof control unit and supported from the ground, and a ground support plate provided at the lower end of the vertical support to prevent the vertical support from falling over on the ground.
[0018] In addition, the above-mentioned ground support plate may be provided with a foldable support member that rotates by a hinge.
[0019]
[0020] Here, the vertical support may be provided with a plurality of detachable structures.
[0021] In this case, the foldable support member may include a foldable support bar that is provided to be rotatable downward from a center portion connected to the vertical support member, and a rotation hinge that supports the foldable support bar to be rotatable only in a downward direction.
[0022] In this case, the power connection part may be provided with a waterproof cover that can be opened and closed.
[0023] In addition, the waterproof control unit may be equipped with a molding type controller PCB, and may be equipped with a power connection unit capable of connecting power on one side.
[0024] Additionally, the waterproof control unit may be provided on the ground support plate.
[0025] In this case, a rechargeable battery is further provided on the ground support plate, and the waterproof control unit controls whether to charge or stop charging the rechargeable battery, and can control whether to supply or cut off power from the rechargeable battery to the BLDC motor (140) provided in the waterproof head unit.
[0026] In addition, the waterproof head and the waterproof control unit can be provided to be detachably attached by a head-side waterproof terminal and a control-side waterproof terminal.
[0027] A waterproof fan according to one embodiment of the present invention is waterproofed throughout, thereby having the effect of preventing breakdown due to liquid inflow.
[0028] In addition, the housing, etc. are treated with anti-static treatment or anti-static material to minimize contamination by dust, etc., and contaminants such as dust can be easily removed when washed with water.
[0029] And, in case of contamination, it has the effect of being easy to clean using a shower or hose without having to disassemble.

[0038] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided to ensure that the disclosure is thorough and complete, and to sufficiently convey the spirit of the invention to those skilled in the art. Like reference numbers designate like elements throughout the specification.
[0039] The present invention relates to a waterproof fan having a molding structure for anti-static and waterproofing, and is particularly characterized in that a BLDC motor is applied and installed inside an anti-static housing with a molding structure, and an anti-static blade is installed to be waterproofed by a retainer oil seal so that it can be washed with water without the need for separate disassembly during cleaning.
[0040] Hereinafter, a waterproof fan according to an embodiment of the present invention will be described in detail with reference to the attached drawings.
[0041] FIG. 1 is a perspective view of a waterproof fan according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing the internal structure of a waterproof fan according to an embodiment of the present invention.
[0042] Referring to FIGS. 1 and 2, the present invention comprises a waterproof head part (100) that provides a ventilation function, a stand (200) that supports the waterproof head part (100) from the ground, and a waterproof control part (300) that can control the operation of the waterproof head part (100).
[0043] Here, the waterproof head part (100) is configured to include an anti-static blade (110) that can generate airflow by rotation, and an anti-static housing (120) that is provided around the outer circumference of the anti-static blade (110) to form a space where airflow is generated while protecting the anti-static blade (110).
[0044] 'Prevention of charge' refers to the function of suppressing the generation of static charges and inducing rapid dispersion and annihilation of generated charges.
[0045] Meanwhile, the blade or housing of the waterproof head part (110) of the present invention is mainly made of plastic. However, due to the nature of the material, plastic has little ability to absorb moisture from the air and has very high insulation resistance, so it has a property of accumulating rather than dissipating generated static electricity. Accordingly, the present invention can prevent the phenomenon of dust being absorbed on the surface of the blade or housing due to accumulated static electricity by applying an antistatic material to the blade or housing of the waterproof head part (110).
[0046] The above-mentioned antistatic material forms a thin film that exhibits antistatic properties on a plastic surface, and can release static electricity generated on the surface when it absorbs moisture in the air.
[0047] The above-mentioned anti-static material may be added to and extruded from a polymer resin forming the blade or housing of the waterproof head portion (100), or may be coated on the surface of the blade or housing of the waterproof head portion (100).
[0048] Among these, the antistatic material used for coating can be manufactured by adding a binder to conductive carbon such as carbon fiber, carbon block, carbon nanotube, indium tin compound, antimony tin compound, metal particles such as silver, and conductive polymers such as polyaniline, polypyrrole, and polythiophene.
[0049] By applying such antistatic treatment or antistatic material, contamination such as dust can be minimized during use of the fan, and even when washing with water, dust can be easily separated and washed with water.
[0050] And, on both sides of the anti-static housing (120), a safety cover (130) is provided that forms a mesh structure in the form of a flesh, and can prevent foreign substances from being rolled in from the outside or a user's body from coming into contact with the anti-static blade (110) and causing a safety accident while maintaining the path through which the air is generated.
[0051] At this time, the safety cover (130) is made of anti-static resin material, so contamination is reduced and contamination can be easily removed when washed with water.
[0052] Alternatively, the safety cover (130) may be provided in a mesh form and may be made of antistatic powder coating or antistatic material.
[0053] A BLDC motor (140) that provides power to rotate the anti-static blade (110) is provided at the rear of the anti-static housing (120).
[0054] The above BLDC motor (140) is installed in a molding structure by a motor molding (150) when installed in an anti-static housing (120).
[0055] And, on the side of the rotation shaft where the BLDC motor (140) and the anti-static blade (110) are connected, the rotation shaft is opened to rotate in the motor molding (150), and a retainer oil seal (151) is installed to maintain waterproof performance and operate.
[0056] At this time, the BLDC motor (140) is installed with a power cable (160) connected for power supply.
[0057] The above power cable (160) is connected from the BLDC motor (140) through the lower part of the motor molding (150) to maintain waterproof performance, and the outer side where the power cable (160) is connected is connected to be waterproof by a cable cover (170) that prevents the inflow of liquid from the outside.
[0058] The above stand (200) is installed to extend to the lower portion of the waterproof head portion (100) and is capable of supporting the waterproof head portion (100) vertically from the ground, and is configured to include a vertical support member (210) extending vertically from the lower portion of the waterproof head portion (100) toward the ground, and a ground support plate (220) provided at the lower portion of the vertical support member (210) and having a circular plate shape to support the vertical support member (210) so that it does not fall over.
[0059] The above waterproof control unit (300) is provided at a position where the waterproof head unit (100) is coupled at the top of the vertical support (210), and can control the operation of the BLDC motor (140) that provides rotational power to the anti-static blade (110).
[0060] This waterproof control unit (300) is configured to include a molding type controller PCB (310) manufactured with a molding structure on the PCB itself to prevent liquid from entering, and a power connection unit (320) that supplies power to a BLDC motor (140).
[0061] Although not shown, the molding type controller PCB (310) may be provided with a control signal input unit in the form of a pressure-type or touch button exposed to the outside of the housing, or a wireless control signal receiving unit such as a remote control. The control signal input unit or the wireless control unit may also be molded for waterproofing, similar to the molding type controller PCB (310), and may be configured to be molded together with the molding type controller PCB (310) as an integral part.
[0062] At this time, the power connection part (320) is provided with a waterproof cover (330) that can connect or disconnect the power and prevent liquid from flowing in after disconnecting the power cable during cleaning.
[0063] This allows for easy cleaning using a shower or hose without having to disassemble each part when contamination by foreign substances occurs, and allows for immediate use after cleaning without requiring a separate drying time.
[0064] FIG. 3 is an exemplary diagram showing a state in which a foldable support and a split vertical support are applied to a stand in a waterproof fan according to the first embodiment of the present invention.
[0065] Referring to FIG. 3, the stand (200) may be equipped with a foldable support member (230) that can be easily carried and stored.
[0066] The above-mentioned folding support member (230) is configured to be rotatable only in the downward direction and not to be rotatable in the upward direction on the surface in contact with the ground, and includes a plurality of folding support bars (231) that support the ground and a rotating hinge (232) that can support the folding support bars (231) to be folded only in the direction of the ground.
[0067] The above-mentioned foldable support bar (231) unfolds when in use and supports the ground to prevent falling over, and can be folded downward when carrying or storing, thereby minimizing the volume for carrying or storing.
[0068] Additionally, the vertical support (210) may be provided with a split structure so as to be composed of a plurality of connectable and detachable segments.
[0069] Accordingly, when in use, multiple joints can be connected to fix the waterproof head (100) at an appropriate height, and when carrying and storing, the joints can be separated to minimize the volume.
[0070] Figure 4 is a perspective view showing an exploded state of a waterproof fan according to one embodiment of the present invention.
[0071] Referring to FIG. 4, the waterproof head unit (100) and the waterproof control unit (300) of the present invention can be provided in a separable manner.
[0072] At this time, the waterproof head part (100) is provided with a head-side waterproof terminal (180) at the bottom, and the waterproof control part (300) is provided with a control part-side waterproof terminal (340) connected to the head-side waterproof terminal (180) at the top.
[0073] Accordingly, by connecting the head-side waterproof terminal (180) and the control-side waterproof terminal (340) to each other, the waterproof function can be maintained and used, and when separated, the head-side waterproof terminal (180) and the control-side waterproof terminal (340) can be easily separated for cleaning, storage, and portability.
[0074] FIG. 5 is an exemplary diagram showing a state in which a waterproof control unit is provided at the bottom of a stand in a waterproof fan according to a second embodiment of the present invention.
[0075] Referring to FIG. 5, the waterproof control unit (300) may be provided on the lower side of the stand (200).
[0076] At this time, the waterproof control unit (300) is provided to be built into the ground support plate (220), so that when connecting the power cable, it is connected to the ground side, so that the user's movement is not restricted and cable management is easy.
[0077] The present invention, which is constructed as described above, prevents liquid inflow through a waterproof function when using an electric fan, so that it can be washed with water without disassembly, and can be used immediately after washing without requiring a separate drying time, without causing any damage to electronic devices.
[0078] FIG. 6 is an implementation diagram showing a state in which a waterproof control unit is provided at the bottom of a stand in a waterproof fan according to a third embodiment of the present invention.
[0079] The embodiment illustrated in FIG. 6 is similar to the embodiment illustrated in FIG. 5 in that the waterproof control unit (300) for controlling the BLDC motor (140) that provides rotational power to the anti-static blade (110) is provided to be built into the ground support plate (220).
[0080] However, in the embodiment illustrated in FIG. 6, the waterproof control unit (300) may further include a rechargeable battery (340) in addition to the molding type controller PCB (310).
[0081] Accordingly, the external power supplied through the control unit side waterproof terminal (340) can charge the rechargeable battery (340) and drive the BLDC motor (140) using the charged power, so that the waterproof fan can be configured to be used wirelessly.
[0082] In addition, according to the waterproof fan according to the present invention, a rechargeable battery is provided so that the fan can be used wirelessly, and the blades can be rotated even when washing with water to maximize the washing efficiency or drying efficiency.
[0083] The above molding type controller PCB (310) can control whether to charge the rechargeable battery (340), prevent overcharging, or stop charging when charging is complete, and can perform a function of supplying or cutting off power supplied from the rechargeable battery (340) to the BLDC motor (140) according to a control signal input by a user received from the aforementioned control signal input unit.
[0084] In this way, when a rechargeable battery (340) is provided on the ground support plate (220), a waterproof head part (100) or the like is provided on the upper part, thereby reducing the possibility of overturning, such as tipping over, which may occur even with a small external force, thereby further improving the stability of the product.
[0085] While this specification has described preferred embodiments of the present invention, those skilled in the art will appreciate that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention as defined in the claims below. Therefore, any modified implementation that fundamentally includes the elements of the claims should be considered within the technical scope of the present invention.
