The screw 80 is inserted into. Then, the cover member 60 is screwed to the back surface 220 by screwing the two screws 80 into the two screw holes 228 of the back surface 220, respectively. When the cover member 60 is screwed to the back surface portion 220, the waterproof member 110 provided on the back surface 60a of the cover member 60 comes into contact with the facing surface 227 of the housing 20 and is in a crushed state. As a result, the waterproof member 110 comes into close contact with the facing surface 227 in a liquidtight manner. The waterproof member 110 does not have to be integrally molded with the cover member 60.

As described above, in the first waterproof structure, the waterproof member 110 is located between the back surface 60a of the cover member 60 and the facing surface 227 of the housing 20 facing the back surface 60a. The waterproof member 110 can reduce the possibility of water entering the accommodating recess 223 covered by the cover member 60. Therefore, it becomes difficult for water to splash on the motor 40 and the jack connector 50.

Further, since the cover member 60 is screwed to the housing 20, the elastic member as the waterproof member 110 can be strongly pressed against the facing surface 227 of the housing 20. As a result, the possibility of water entering the accommodating recess 223 can be further reduced. Therefore, it becomes more difficult for water to splash on the motor 40 and the jack connector 50.

The method of fixing the cover member 60 to the housing 20 may be a method other than screwing. For example, the back surface 60a of the cover member 60 may be provided with a claw portion, and the back surface portion 220 may be provided with a fitting recess for fitting the claw portion.

<Second waterproof structure>
The second waterproof structure includes a waterproof member related to the wiring 70. FIG. 10 is a diagram schematically showing a structure of the jack connector 50 in the vicinity of the terminal 52. As shown in FIG. 10, at the end of each electric wire 71 of the wiring 70, the wire 71a is exposed from the insulating coating 71b. The wire 71a is soldered to the terminal 52 of the jack connector 50. The second waterproof structure includes a waterproof member 120 that covers the solder connection portion between the wiring 70 and the portion to which the wiring 70 is soldered. The waterproof member 120 is made of, for example, a silicone resin. For example, the waterproof member 120 is formed by applying a silicone resin to the solder connection portion.

The waterproof member 120 is provided for each electric wire 71. The waterproof member 120 covers the solder connection portion between the electric wire 71 and the terminal 52. For example, the waterproof member 120 covers the entire area of the exposed wire 71a and the entire area of the terminal 52 to which the wire 71a is soldered. As a result, the strands 71a and the terminals 52 are not exposed.

As described above, since the waterproof member 120 covers the solder connection portion between the electric wire 71 and the terminal 52 to which the electric wire 71 is soldered, it is difficult for water to splash on the solder connection portion. This makes it possible to reduce the possibility that a defect will occur in the solder connection portion.

The solder connection portion between one electric wire 71 and one terminal 52 and the solder connection portion between the other electric wire 71 and the other terminal 52 may be covered with a common waterproof member 120. Further, the waterproof member 120 may include a heat-shrinkable tube that covers the solder connection portion between the electric wire 71 and the terminal 52. In this case, silicone resin or the like may be applied to both end edges of the heat-shrinkable tube in order to prevent water from entering through the opening of the heat-shrinkable tube.

FIG. 11 is a diagram schematically showing a connection portion between the connector 72 of the wiring 70 and the connector 484 of the control board 48. The second waterproof structure may include a waterproof member 121 that covers the connection portion between the connector 72 and the connector 484 so that water does not enter. The waterproof member 121 is made of, for example, a silicone resin. For example, the waterproof member 121 is formed by applying a silicone resin to the connection portion between the connector 72 and the connector 484.

The connector 72 is, for example, a receptacle, and the connector 484 is, for example, a plug. The connector 72 fits into the connector 484. The waterproof member 121 covers the fitting portion so that water does not enter from the fitting portion between the connector 72 and the connector 484.

As described above, since the waterproof member 121 covers the connection portion between the connector 72 and the connector 484, the possibility of water entering the connectors 484 and 72 from the connection portion can be reduced. Therefore, it is possible to reduce the possibility that a defect in the electrical connection between the wiring 70 and the control board 48 will occur.

The waterproof member 121 may include a heat-shrinkable tube that covers the connection portion between the connector 72 and the connector 484. In this case, silicone resin or the like may be applied to both end edges of the heat-shrinkable tube in order to prevent water from entering through the opening of the heat-shrinkable tube.

FIG. 12 is a perspective view schematically showing an example of the wiring 70 and the connector 484. As shown in FIG. 12, each wire 71 of the wiring 70 has a terminal 71c at its end. The connector 72 of the wiring 70 is provided with two insertion ports 73 into which the terminals 71c of the two electric wires 71 are inserted. When water enters the insertion port 73, a defect in the electrical connection between the wiring 70 and the control board 48 may occur.

Therefore, as shown in FIG. 13, the second waterproof structure may include a waterproof member 122 that covers the insertion port 73. The waterproof member 122 is made of, for example, a silicone resin. For example, the waterproof member 122 is formed by applying a silicone resin to each insertion port 73. The waterproof member 122 makes it difficult for water to enter through the insertion port 73 into which the electric wire 71 is inserted. Therefore, the possibility of defective electrical connection between the wiring 70 and the motor 40 is reduced.

The waterproof member 122 may be provided with a heat shrinkable tube that covers the insertion port 73. For example, when a heat-shrinkable tube covering the wiring 70 is provided from the connector 72 to the electric wire 71, the insertion port 73 is covered with the heat-shrinkable tube. Further, a heat shrinkable tube may be provided from the connector 484 to the electric wire 71 to cover the connector 484 and the wiring 70. In this case, the heat-shrinkable tube covers the connection portion between the connector 72 and the connector 484 and also covers the insertion port 73 of the connector 72. When the heat-shrinkable tube is provided, silicone resin or the like may be applied to both ends of the heat-shrinkable tube in order to prevent water from entering through the opening of the heat-shrinkable tube.

The second waterproof structure does not have to be provided with the waterproof member 120. Further, the second waterproof structure does not have to include the waterproof member 121. Further, the second waterproof structure does not have to include the waterproof member 122. The second waterproof structure may include at least one of the waterproof members 120, 121, 122.

Further, each electric wire 71 of the wiring 70 may be directly soldered to the control board 48 in the motor housing 41. In this case, the solder connection portion between the electric wire 71 and the control board 48 may be covered with a waterproof member.

<Third waterproof structure>
The third waterproof structure includes a waterproof member 130 for preventing water from entering the connection portion between the jack connector 50 and the plug connector 811. As shown in FIGS. 5 and 8 above, the waterproof member 130 is located in the housing 20 between the insertion hole 225b into which the plug connector 811 is inserted and the plug connector 811. Specifically, the waterproof member 130 is located between the insertion hole 225b and the insertion port 51 in the jack connector 50 into which the plug connector 811 is inserted. The waterproof member 130 is an annular member. The waterproof member 130 is, for example, an O-ring made of waterproof rubber.

The annular waterproof member 130 is fixed in the connector accommodating portion 225 so that the hole at the center thereof faces the insertion port 51 of the jack connector 50 and the insertion hole 225b of the housing 20. For example, a groove is formed on the inner surface of the connector accommodating portion 225, and the waterproof member 130 is fitted in the groove. The waterproof member 130 is in contact with, for example, the jack connector 50. In this example, the inner surface of the connector accommodating portion 225 and the back surface 60a of the cover member 60 covering the connector accommodating portion 225 form a peripheral wall surface that surrounds the annular waterproof member 130 in the circumferential direction. The waterproof member 130 adheres to the peripheral wall surface in a liquidtight manner.

FIG. 14 is a diagram schematically showing an example of a state in which the jack connector 50 and the waterproof member 130 are viewed from the lower side (in other words, from the insertion hole 225b side). In FIG. 14, the waterproof member 130 is shown with diagonal lines. As shown in FIG. 14, the inner diameter of the annular waterproof member 130, in other words, the diameter of the central hole 131 of the waterproof member 130 is smaller than the diameter of the insertion port 51 of the jack connector 50. When the jack connector 50 and the waterproof member 130 are viewed from the insertion hole 225b side, the hole 131 of the waterproof member 130 is located concentrically with, for example, the insertion port 51 of the jack connector 50. When the jack connector 50 and the waterproof member 130 are viewed from the insertion hole 225b side, the peripheral edge around the insertion port 51 of the jack connector 50 is hidden behind the waterproof member 130 so that it cannot be visually recognized. Further, the diameter of the hole 131 of the waterproof member 130 is smaller than the outer diameter of the plug connector 811 inserted into the insertion port 51.

When the plug connector 811 is inserted into the insertion port 51 of the jack connector 50, the plug connector 811 is first inserted into the insertion hole 225b of the housing 20. Next, the plug connector 811 is inserted into the hole 131 of the waterproof member 130 located on the back side of the insertion port 51. At this time, the plug connector 811 is inserted into the hole 131 of the waterproof member 130 while expanding the diameter of the hole 131. Then, the plug connector 811 is inserted into the insertion port 51 of the jack connector 50 on the back side of the waterproof member 130.

FIG. 15 is a diagram schematically showing an example of how the plug connector 811 is inserted into the jack connector 50. When the plug connector 811 is inserted into the jack connector 50, the outer periphery of the portion of the plug connector 811 exposed from the jack connector 50 is surrounded by the annular waterproof member 130. Since the plug connector 811 is inserted into the hole 131 while expanding the diameter of the hole 131 of the waterproof member 130, the inside of the waterproof member 130 is in close contact with the outer periphery of the plug connector 811 in a liquidtight manner. On the other hand, as described above, the outer side of the waterproof member 130 is in close contact with the peripheral wall surface formed by the inner surface of the connector accommodating portion 225 and the back surface 60a of the cover member 60 in a liquidtight manner. As a result, water entering through the insertion hole 225b of the housing 20 is less likely to enter the jack connector 50 side beyond the waterproof member 130.

As described above, in this example, when the plug connector 811 is connected to the jack connector 50, the waterproof member 130 surrounds the outer circumference of the plug connector 811. Therefore, it becomes difficult for water to enter the jack connector 50 side of the waterproof member 130. This makes it difficult for water to enter the connection portion between the plug connector 811 and the jack connector 50. Therefore, the possibility of poor connection between the plug connector 811 and the jack connector 50 is reduced.

<4th waterproof structure>
The fourth waterproof structure includes the waterproof member 140 shown in FIG. 5 described above. The waterproof member 140 is an annular member. The waterproof member 140 is located between the tubular convex surface 224b on the outside of the motor accommodating portion 224 and the tubular connecting portion 32 of the blade portion 30 that covers the tubular convex surface 224b. The waterproof member 140 surrounds the tubular convex surface 224b in the circumferential direction. In other words, the waterproof member 140 surrounds the peripheral wall portion 2241 of the motor accommodating portion 224 in the circumferential direction. The waterproof member 140 is located between the peripheral wall portion 2241 and the peripheral wall portion 321 of the tubular connecting portion 32 that surrounds the peripheral wall portion 2241 in the circumferential direction. In the example of FIG. 5, the waterproof member 140 is located between the peripheral end portion on the rear side of the peripheral wall portion 321 and the peripheral wall portion 2241.

As described above, the fourth waterproof structure is a waterproof member 140 that surrounds the tubular convex surface 224b in the circumferential direction between the tubular connecting portion 32 of the blade portion 30 and the tubular convex surface 224b on the outer side of the motor accommodating portion 224. To be equipped. As a result, it is possible to reduce the possibility that water enters through the gap between the tubular connecting portion 32 and the tubular convex surface 224b and the motor 40 is splashed with water.

FIG. 16 is a schematic view showing an example of how water enters through the gap between the tubular connecting portion 32 and the tubular convex surface 224b when the waterproof member 140 is not provided. The fan 10 shown in FIG. 16 is not provided with the waterproof member 150 and the cover member 160, which will be described later. Arrow 960 shown in FIG. 16 indicates the flow of water.

As shown in FIG. 16, for example, consider a case where water that has entered the housing 20 from the exhaust side through the exhaust port 222 enters the gap between the tubular connecting portion 32 and the tubular convex surface 224b. In this case, water may pass through the gap between the tubular connecting portion 32 and the tubular convex surface 224b and enter the through hole 2240a in the bottom portion 2240 of the motor accommodating portion 224 through which the motor shaft 44 passes. The water that has entered the through hole 2240a may enter the housing 41 through the through hole through which the motor shaft 44 passes and the gap between the inner ring and the outer ring of the bearing 46. As a result, the motor 40 may not operate normally.

On the other hand, when the fan 10 is provided with the waterproof member 140, it becomes difficult for water to enter the gap between the tubular connecting portion 32 and the tubular convex surface 224b. This makes it possible to reduce the possibility of water splashing on the motor 40.

Further, in this example, the control board 48 is provided in the motor housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by the waterproof member 140.

The waterproof member 140 may be, for example, a bearing having waterproof performance. In this case, the outer ring of the bearing is fixed to the inner peripheral surface of the peripheral wall portion 321 of the tubular connecting portion 32. Further, the inner ring of the bearing is fixed to the outer peripheral surface of the peripheral wall portion 2241 of the motor accommodating portion 224. This reduces the possibility that the waterproof member 140 hinders the rotation of the blade portion 30. In a bearing having waterproof performance, for example, a gap between an inner ring and an outer ring (for example, a space where a ball exists) is sealed with resin, metal, or the like.

The waterproof member 140 may be other than a bearing. For example, the waterproof member 140 may be composed of an O-ring made of waterproof rubber. Further, the waterproof member 140 may be composed of an annular oil seal.

<Fifth waterproof structure>
The fifth waterproof structure includes the waterproof member 150 shown in FIG. The waterproof member 150 is located between the tubular concave surface 224c inside the motor accommodating portion 224 and the motor 40. The waterproof member 150 surrounds the motor shaft 44 along the circumferential direction of the tubular concave surface 224c. The waterproof member 150 is, for example, an O-ring made of waterproof rubber.

FIG. 17 is an enlarged diagram schematically showing the vicinity of the waterproof member 150. As shown in FIG. 17, the motor housing 41 has a convex portion 410 provided on the bottom portion 2240 of the motor accommodating portion 224 and projecting into a through hole 2240a through which the motor shaft 44 passes. The convex portion 410 is, for example, a tubular convex portion. The bearing 46 is fixed to the tubular concave surface inside the convex portion 410. The motor shaft 44 penetrates the convex portion 410, passes through the through hole 2240a of the motor accommodating portion 224, and is fixed to the connecting portion 32 of the blade portion 30.

The annular waterproof member 150 surrounds the tubular convex portion 410 of the housing 41 along the circumferential direction. The waterproof member 150 is sandwiched between the peripheral portion 2240b located around the through hole 2240a and the motor housing 41 in the bottom portion 2240 of the motor accommodating portion 224. The waterproof member 150 is in liquid-tight contact with the outer surface of the housing 41 and the tubular concave surface 224c inside the motor accommodating portion 224.

Here, in this example, although the waterproof member 140 is provided between the motor accommodating portion 224 and the connecting portion 32 of the blade portion 30, water allows water to pass through a gap between the motor accommodating portion 224 and the connecting portion 32. Through it, it may enter the through hole 2240a of the motor accommodating portion 224. In this case, when the waterproof member 150 is not present, as shown by arrow 961 in FIG. 18, water enters between the housing 41 of the motor 40 and the motor accommodating portion 224 through the through hole 2240a, and the motor 40 May turn behind. As a result, water may splash on the wiring 70 and the like on the rear side of the motor 40.

Further, in this example, although the waterproof member 110 is provided between the cover member 60 and the housing 20, water may enter the motor accommodating portion 224 from between the cover member 60 and the housing 20. In this case, when the waterproof member 150 is not present, as shown by arrow 962 in FIG. 17, water enters between the housing 41 of the motor 40 and the motor accommodating portion 224, and further, on the front side of the motor 40. May also enter. As a result, water may enter the housing 41 through the through hole through which the motor shaft 44 passes and the bearing 46, as in FIG. 16 described above.

In this example, since the fifth waterproof structure includes the waterproof member 150, the possibility that water will flow to the rear side of the motor 40 through the path shown by the arrow 961 in FIG. 18 is reduced. It also reduces the possibility of water entering the housing 41 through the path indicated by arrow 962.

Further, in this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by the waterproof member 150.

In the example of FIG. 17, the waterproof member 150 is located near the through hole 2240a, but the position of the waterproof member 150 is not limited to this. For example, as shown in FIG. 19, the waterproof member 150 may be provided so as to surround a portion on the rear side of the motor housing 41. Note that in FIGS. 17 to 19, the control board 48 is not shown.

<6th waterproof structure>
The sixth waterproof structure includes a cover member 160 shown in FIG. The cover member 160 covers a through hole through which the motor shaft 44 penetrates in the connecting portion 32 of the blade portion 30. The cover member 160 is attached to the connecting portion 32 with screws or the like. The cover member 160 is made of, for example, a resin.

FIG. 20 is a diagram schematically showing an example of a state in which the connecting portion 32 is viewed from the front side with the cover member 160 removed. In FIG. 20, diagonal lines are shown on the motor shaft 44 and the metal fitting 33. The metal fitting 33 included in the flat plate portion 320 of the connecting portion 32 has a through hole 33a through which the motor shaft 44 penetrates. The cover member 160 covers the intake side opening 33aa in the through hole 33a. In other words, the cover member 160 covers the opening 33aa of the through hole 33a on the side opposite to the opening surface on the motor accommodating portion 224 side.

FIG. 21 is a diagram showing an example of a state in which the cover member 160 is attached to the connecting portion 32 shown in FIG. As shown in FIG. 21, the outer shape of the cover member 160 is, for example, circular in a plan view. The cover member 160 is attached to the flat plate portion 320 so as to cover the entire convex portion 320a of the connecting portion 32, for example. As a result, the end face of the motor shaft 44 exposed from the flat plate portion 320 is covered with the cover member 160. Further, the surface of the metal fitting 33 on the intake side exposed from the flat plate portion 320 is covered with the cover member 160. Further, the opening 33aa on the intake side in the through hole 33a of the metal fitting 33 is covered with the cover member 160.

In this way, since the cover member 160 covers the opening 33aa on the intake side of the through hole 33a through which the motor shaft 44 passes in the connecting portion 32, it becomes difficult for water to enter through the opening 33aa. Water entering through the opening 33aa may enter the through hole 2240a of the motor accommodating portion 224 and then into the housing 41 of the motor 40, as shown in FIG. The cover member 160 makes it difficult for water to enter through the opening 33aa, so that the possibility of water entering the housing 41 can be reduced.

Further, in this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by the cover member 160.

<7th waterproof structure>
The seventh waterproof structure includes a waterproof member 170 that can be attached to and detached from the jack connector 50. The waterproof member 170 covers the insertion port 51 of the jack connector 50. It can be said that the waterproof member 170 is a waterproof cover. The waterproof member 170 is made of, for example, waterproof rubber.

FIG. 22 is a diagram schematically showing an example of how the waterproof member 170 is attached to the jack connector 50. As shown in FIG. 22, the waterproof member 170 includes, for example, a main body portion 171 that covers the insertion port 51, and an attachment portion 172 for attaching the waterproof member 170 to the housing 20. The main body 171 has, for example, a protrusion that is inserted into the insertion port 51. When the protrusion is inserted into the insertion port 51, the insertion port 51 is covered with the main body portion 171. The main body 171 is removable from the jack connector 50. When using the fan 10, the user removes the main body 171 from the jack connector 50 and inserts the plug connector 811 into the exposed insertion port 51.

One end of the mounting portion 172 is connected to the main body portion 171. The other end of the mounting portion 172 is connected to, for example, the housing 20. As a result, even if the main body 171 is removed from the jack connector 50, the possibility that the main body 171 is lost is reduced.

As described above, the seventh waterproof structure includes a waterproof member 170 that is removable from the jack connector 50 and covers the insertion port 51 of the jack connector 50. As a result, when the fan 10 is not used, the waterproof member 170 can cover the insertion port 51. Therefore, it is possible to prevent water from entering through the insertion port 51 when the fan 10 is not in use.

<8th waterproof structure>
In this example, although the waterproof member 140 is provided between the motor accommodating portion 224 and the connecting portion 32 of the blade portion 30, water may enter the gap between the motor accommodating portion 224 and the connecting portion 32. is there. Further, once water enters the gap between the motor accommodating portion 224 and the connecting portion 32, the presence of the waterproof member 140 makes it easy for water to collect in the gap.

Therefore, in this example, by providing the through hole 325 in the connecting portion 32, the water that has entered the gap between the motor accommodating portion 224 and the connecting portion 32 can be discharged to the outside of the connecting portion 32. Achieve a waterproof structure.

FIG. 23 is a schematic cross-sectional view showing an enlarged structure near the connecting portion 32. For convenience of explanation, FIG. 23 shows a fan 10 without the waterproof members 140 and 150 and the cover member 160. As shown in FIG. 23, in the connecting portion 32, the peripheral wall portion 321 is provided with a plurality of through holes 325 penetrating in the thickness direction thereof. Further, the flat plate portion 320 is provided with a plurality of through holes 325 penetrating in the thickness direction thereof.

As shown by arrow 965, the water that has entered the gap between the motor accommodating portion 224 and the connecting portion 32 is discharged to the outside of the connecting portion 32 from the through holes 325 provided in the peripheral wall portion 321 and the flat plate portion 320. Will be done. As a result, water is less likely to collect in the gap between the motor accommodating portion 224 and the connecting portion 32, and the motor 40 is less likely to get wet with water. The number and location of the through holes 325 provided in the connecting portion 32 are not limited to the above example.

In this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by providing the through hole 325 in the connecting portion 32.

As described above, the first to eighth waterproof structures have been described as the waterproof structures of the fan 10 according to this example. The fan 10 does not have to include a part of the first to eighth waterproof structures. That is, the fan 10 may include at least one of the first to eighth waterproof structures. Further, the fan 10 may have a waterproof structure different from the first to eighth waterproof structures. Other waterproof structures will be described below.

<9th waterproof structure>
FIG. 24 is a diagram schematically showing an example of a state in which the structures of the motor 40, the motor accommodating portion 224, and the blade portion 30 are viewed from the exhaust side. FIG. 24 shows a cross section of the motor accommodating portion 224. Further, the fan 10 shown in FIG. 24 is not provided with the waterproof member 140.

As shown in FIG. 24, the gap 500 between the motor accommodating portion 224 and the connecting portion 32 of the blade portion 30 has an annular opening surface 501 on the exhaust side. If water enters the gap 500 from the annular opening surface 501, water may splash on the motor 40 as described above.

The ninth waterproof structure of this example includes a protrusion 180 for making it difficult for water to enter from the annular opening surface 501. The protrusion 180 is provided on the outer tubular convex surface 224b of the motor accommodating portion 224.

FIG. 25 is a diagram schematically showing an example in which a protrusion 180 is provided in the structure shown in FIG. 24. FIG. 26 is a diagram schematically showing an example of the cross-sectional structure of the motor 40, the motor accommodating portion 224, the blade portion 30, and the protrusion 180. The fan 10 shown in FIGS. 26 and 26 is not provided with the waterproof members 140 and 150 and the cover member 160. Further, in FIG. 26, the motor 40 is shown in a simplified manner. Further, in FIG. 26, only a part of the plurality of blades 31 included in the blade portion 30 is shown.

As shown in FIGS. 25 and 26, the protrusion 180 is provided on the outer peripheral surface of the motor accommodating portion 224 so as to project outward from the outer peripheral surface of the peripheral wall portion 2241. The protrusion 180 is made of, for example, a resin. The protrusion 180 is formed integrally with, for example, the motor accommodating portion 224. The protrusion 180 is an annular plate-shaped protrusion, and surrounds the peripheral wall portion 2241 in the circumferential direction so as to cover the annular opening surface 501. In other words, the protrusion 180 surrounds the outer tubular convex surface 224b of the motor accommodating portion 224 in the circumferential direction so as to cover the annular opening surface 501. It can be said that the protrusion 180 is a flange portion. The protrusion 180 is inclined toward, for example, the annular opening surface 501. In other words, the protrusion 180 is inclined toward the intake side.

As described above, the protrusion 180 surrounds the outer tubular convex surface 224b of the motor accommodating portion 224 in the circumferential direction so as to cover the annular opening surface 501. This makes it difficult for water to enter the gap 500 from the annular opening surface 501. As a result, the possibility of water splashing on the motor 40 can be reduced.

Further, in this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by the protrusion 180 covering the annular opening surface 501.

The shape of the protrusion 180 is not limited to the above example. For example, the protrusion 180 may have the shape shown in FIG. 27. In the example of FIG. 27, the protrusion 180 is not inclined toward the intake side, and the main surface on the front side of the protrusion 180 (in other words, the main surface covering the annular opening surface 501) is uneven. An annular convex portion 180b and an annular concave portion 180a are formed concentrically on the main surface on the front side of the protrusion 180.

Further, in the example of FIG. 27, the protrusion 190 is provided on the tubular convex surface 32b on the outer side of the connecting portion 32. The protrusion 190 is made of, for example, a resin. The protrusion 190 is formed integrally with, for example, the connecting portion 32. The protrusion 190 is provided on the peripheral wall portion 321 of the connecting portion 32. The protrusion 190 is an annular protrusion and surrounds the peripheral wall portion 321 in the circumferential direction. In other words, the protrusion 190 surrounds the outer tubular convex surface 32b of the connecting portion 32 in the circumferential direction. It can be said that the protrusion 190 is a flange. The protrusion 190 surrounds the tubular convex surface 32b in the circumferential direction so as to face the protrusion 180. The main surface on the rear side of the protrusion 190 is uneven. The rear main surface of the protrusion 190 faces the front main surface of the protrusion 180. An annular convex portion 190b and an annular concave portion 190a are formed concentrically on the main surface on the rear side of the protrusion 190.

The annular convex portion 180b of the protrusion 180 has entered the annular recess 190a of the protrusion 190. Further, the annular convex portion 190b of the protrusion 190 is inserted into the annular recess 180a of the protrusion 180. As a result, the gap 510 between the protrusion 180 and the protrusion 190 constitutes a labyrinth gap that communicates with the annular opening surface 501.

As described above, when the gap 510 between the protrusion 180 and the protrusion 190 forms a labyrinth gap communicating with the annular opening surface 501, it becomes more difficult for water to enter the gap 500 from the annular opening surface 501. As a result, the possibility of water splashing on the motor 40 is further reduced.

<10th waterproof structure>
In the above example, one end of the cable 810 extending from the battery device 800 is connected to the jack connector 50. Therefore, water may enter from the connection portion between the jack connector 50 and the cable 810, that is, the connection portion between the jack connector 50 and the plug connector 811.

Therefore, in the waterproof structure of this example, one end of the cable 810 is non-detachably fixed in the housing 20. As a result, water does not enter from the connection portion between the jack connector 50 and the cable 810.

When one end of the cable 810 is non-detachably fixed in the housing 20, for example, a terminal in which one end of the cable 810 is fixed in the connector accommodating portion 225 (the connector accommodating portion 225 in which the connector 50 is not accommodated). Is provided. Hereinafter, this terminal may be referred to as a cable fixing terminal.

One end of the cable 810 is, for example, soldered to the cable fixing terminal. Further, one end of each electric wire 71 of the wiring 70 is, for example, soldered to the cable fixing terminal. As a result, the electric power generated by the battery device 800 is supplied to the motor 40. The other end of the cable 810 is taken out of the housing 20 as shown in FIG. In this example, the insertion hole 225b of the housing 20 is the take-out hole 225b from which the cable 810 is taken out. In the example of FIG. 28, the cable 810 includes a connector 812 at the other end. The connector 812 is removable from the battery device 800.

An annular waterproof member 200 may be provided in the connector accommodating portion 225 near the take-out hole 225b. In this case, the cable 810 is passed through the through hole 201 at the center of the waterproof member 200, as shown in FIG. 29. The inside of the waterproof member 200 is in close contact with the outer periphery of the cable 810 in a liquidtight manner. Further, the inner surface of the connector accommodating portion 225 and the back surface 60a of the cover member 60 covering the connector accommodating portion 225 form a peripheral wall surface surrounding the annular waterproof member 200 in the circumferential direction. The waterproof member 200 adheres to the peripheral wall surface in a liquidtight manner. This makes it difficult for water to enter the inside of the waterproof member 200.

<11th waterproof structure>
When water enters the housing 20 from the intake side, the water may enter the motor 40 by passing through the gap 500 between the motor accommodating portion 224 and the connecting portion 32 of the blade portion 30.

Therefore, in the waterproof structure of this example, when the fan 10 is viewed from the intake side, the entire area of the connecting portion 32 of the blade portion 30 behind the central portion 210b in the intake portion 210 where the intake port 210a is not provided. The diameter of the central portion 210b is increased so that it can be hidden. FIG. 30 is a diagram schematically showing an example of the situation. In FIG. 30, only the state of the central portion 210b and the blade portion 30 when the fan 10 is viewed from the intake side is shown.

As shown in FIG. 30, when the fan 10 is viewed from the intake side, the outer shape of the central portion 210b is located outside the outer shape of the connecting portion 32, that is, the outer circumference of the peripheral wall portion 321 of the connecting portion 32. As a result, the entire area of the connecting portion 32 is hidden behind the central portion 210b.

In this way, by enlarging the outer shape of the central portion 210b that constitutes the closed region when the fan 10 is viewed from the intake side, it becomes difficult for water to enter from the intake portion 210. As a result, it becomes difficult for the motor 40 to be engaged.

Further, in this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by enlarging the outer shape of the central portion 210b.

When the fan 10 is viewed from the exhaust side, the outer shape of the cover member 60 may be so large that the entire area of the connecting portion 32 is hidden behind the cover member 60. FIG. 31 is a diagram schematically showing an example of the situation. FIG. 31 shows only the appearance of the cover member 60 and the blade portion 30 when the fan 10 is viewed from the exhaust side.

As shown in FIG. 31, when the fan 10 is viewed from the exhaust side, the outer shape of the cover member 60 is located outside the outer shape of the connecting portion 32. As a result, the entire area of the connecting portion 32 is hidden behind the cover member 60. By enlarging the outer shape of the cover member 60 in this way, it becomes difficult for water to enter the fan 10 from the exhaust side. As a result, it becomes difficult for the motor 40 to be engaged.

Further, in this example, the control board 48 is provided in the housing 41. Therefore, not only the motor 40 but also the control board 48 can reduce the possibility of being splashed with water by enlarging the outer shape of the cover member 60.

In the eleventh waterproof structure, when the fan 10 is viewed from the intake side, a part of the outer shape of the connecting portion 32 may be located outside the outer shape of the central portion 210b. Further, when the fan 10 is viewed from the exhaust side, a part of the outer shape of the connecting portion 32 may be located outside the outer shape of the cover member 60.

As described above, the first to eleventh waterproof structures have been described as the waterproof structures for the fan 10. The fan 10 may have a waterproof structure other than the first to eleventh waterproof structures. For example, the motor 40 itself may have a waterproof structure. For example, the motor 40 may be provided with a waterproof structure that makes it difficult for water to enter the housing 41. Further, the fan 10 may include at least one of the first to eleventh waterproof structures.

<Other examples of clothing fans>
In the above example, the control board 48 drives the motor 40 based on the output signal of the sensor unit 483, but the motor 40 may be sensorlessly driven. FIG. 32 is a diagram showing an example of the configuration of a control board 48 (also referred to as a control board 48A) that performs sensorless drive to the motor 40.

As shown in FIG. 32, the control board 48A does not include a sensor unit 483 that detects the rotational position of the rotor 43. In the control board 48A, the control circuit 481 obtains the rotation position of the rotor 43 without using the output signal of the sensor that detects the rotation position of the rotor 43. The control circuit 481 detects, for example, the induced voltage generated in the U-phase coil, the V-phase coil, and the W-phase coil of the stator 42, and obtains the rotation position of the rotor 43 based on the detection result. Then, the control circuit 481 controls the rotation of the rotor 43 by controlling the inverter 482 based on the obtained rotation position of the rotor 43. The control circuit 481 detects the induced voltage generated in the U-phase coil, the V-phase coil, and the W-phase coil by monitoring the drive signal output by the inverter 482 to the U-phase coil, the V-phase coil, and the W-phase coil. Can be done.

In the above example, the control board 48, the stator 42 of the motor 40, and the rotor 43 are arranged in the same space, but the arrangement space in which the control board 48 is arranged and the arrangement in which the stator 42 and the rotor 43 are arranged are arranged. The space may be divided by a wall portion. FIG. 33 is a diagram showing an example of a partial cross-sectional structure of the fan 10 (also referred to as a fan 10A) in this case.

As shown in FIG. 33, the control board 48 is provided, for example, on the outside of the motor housing 41 and in the accommodating recess 223. The control board 48 is fixed to, for example, the back surface 60a of the cover member 60. FIG. 34 is a diagram showing an example of how the control board 48 is fixed to the back surface 60a of the cover member 60. Various methods can be considered as a method of fixing the control board 48 to the cover member 60. The control board 48 may be fixed to the cover member 60 by, for example, a fitting method. Further, the control board 48 may be screwed to the cover member 60. Further, the control board 48 may be joined to the cover member 60 with an adhesive tape, a silicone resin, or the like.

The fan 10A includes, for example, the above-mentioned first waterproof structure. That is, the fan 10 includes the above-mentioned waterproof member 110 located between the cover member 60 and the back surface portion 220 of the housing 20. The waterproof member 110 is fixed to, for example, the back surface 60a of the cover member 60. As shown in FIG. 34, the control board 48 is located inside the annular waterproof member 110.

The fan 10A is provided with a wall portion 600 that separates the arrangement space in which the control board 48 is arranged in the housing 20 and the arrangement space in which the stator 42 and the rotor 43 of the motor 40 are arranged in the housing 20. In this example, the wall portion 600 is composed of a part of the motor housing 41. Specifically, the flat portion on the rear side of the cylindrical motor housing 41 constitutes the wall portion 600.

Further, in this example, the control board 48 includes a connector 485 for electrically connecting the motor 40 and the control board 48. The connector 485 is mounted on the substrate 480. For example, the wiring 470 extending from the motor 40 is connected to the connector 485. The connector 484 of the control board 48 and the jack connector 50 are electrically connected to each other by wiring 70, for example, as shown in FIG. 8 or the like described above.

FIG. 35 is a diagram schematically showing an example in which the connector 485 and the wiring 470 are connected. The wiring 470 includes, for example, three electric wires 471 and a connector 472 to which the three electric wires 471 are connected. The three electric wires 471 extend from the inside to the outside of the motor housing 41, and the connector 472 is connected to the tip of the three electric wires 471. Like the wire 71 of the wire 70, each wire 471 has a terminal at its end. Similar to the connector 72 of the wiring 70, the connector 472 is provided with two insertion ports into which the terminals of the two electric wires 471 are inserted. The motor housing 41 is provided with a through hole 41a through which three electric wires 471 pass. The connector 472 is, for example, a receptacle, and the connector 485 is, for example, a plug. The connector 472 fits into the connector 485.

One end of the three electric wires 471 on the side opposite to the connector 472 side is electrically connected to the U-phase coil, the V-phase coil, and the W-phase coil of the stator 42, respectively, in the motor housing 41, for example. One end of the electric wire 471 may be directly connected to the coil of the stator 42, or may be connected via a member such as a terminal. The inverter 482 of the control board 48 is electrically connected to the U-phase coil, the V-phase coil, and the W-phase coil of the stator 42 through the connector 485 and the wiring 470. The inverter 482 can give a drive signal to each of the U-phase coil, the V-phase coil, and the W-phase coil through the connector 485 and the wiring 470.

As described above, the fan 10A is provided with a wall portion 600 that separates the arrangement space in which the control board 48 is arranged in the housing 20 and the arrangement space in which the stator 42 and the rotor 43 are arranged in the housing 20.

On the other hand, as shown in FIG. 5 and the like described above, when the wall portion 600 is not provided and the control board 48, the stator 42, and the rotor 43 are arranged in the same space, the motor 40 It is necessary to take waterproof measures for both the control board 48 and the control board 48. Therefore, waterproof measures may be complicated.

When the wall portion 600 is provided as in this example, it is possible to individually take waterproof measures for the control board 48 and waterproof measures for the motor 40. Therefore, it becomes easy to take waterproof measures for the fan 10A.

Further, in this example, the control board 48 is located in the accommodating recess 223 covered with the cover member 60, and the waterproof member 110 is located between the cover member 60 and the housing 20, so that the control board 48 is water. It becomes difficult to get wet.

Further, in this example, since the control board 48 is fixed to the back surface 60a of the cover member 60, the control board 48 can be arranged in the accommodating recess 223 by attaching the cover member 60 to the housing 20. .. Therefore, the assembly workability of the fan 10A is improved.

The control board 48 of the fan 10A may have the configuration shown in FIG. 7 or the configuration shown in FIG. 32. In the latter case, that is, when the control board 48 drives the motor 40 sensorlessly, there is no sensor for detecting the rotational position of the motor 40, so it is necessary to arrange the control board 48 near the motor 40. Absent. Therefore, the degree of freedom in arranging the control board 48 is improved. For example, as in this example, the control board 48 can be fixed to the cover member 60.

The fan 10A may be provided with the above-mentioned second waterproof structure. For example, the solder connection portion between the electric wire 71 of the wiring 70 and the terminal 52 of the jack connector 50 may be covered with the waterproof member 120 as shown in FIG. 10 above. Further, the connection portion between the connector 484 of the control board 48 and the connector 72 of the wiring 70 may be covered with the waterproof member 121 as shown in FIG. 11 above. Further, as shown in FIG. 13 described above, the insertion port 73 of the connector 72 may be covered with the waterproof member 122.

Further, the connection portion between the connector 485 of the control board 48 and the connector 472 of the wiring 470 may be covered with the waterproof member 121 as in FIG. Further, the insertion port of the connector 472 into which the terminal of the electric wire 471 is inserted may be covered with the waterproof member 122 as in FIG.

Further, as shown in FIG. 36, the control board 48 may be covered with the waterproof member 650. This makes it difficult for the control board 48 to get wet with water. The waterproof member 650 is made of, for example, a silicone resin. For example, the waterproof member 650 is formed by applying the silicone resin to the back surface 60a of the cover member 60 so as to cover the control substrate 48.

In the example of FIG. 36, the waterproof member 650 covers, for example, the connection portion between the connector 484 and the connector 72. As a result, it becomes difficult for water to enter from the connection portion between the connector 484 and the connector 72, as in the case where the waterproof member 121 is provided. Further, in the example of FIG. 36, the waterproof member 650 covers the insertion port 73 of the connector 72. As a result, it becomes difficult for water to enter from the insertion port 73, as in the case where the waterproof member 122 is provided. Further, since the waterproof member 650 covers the connection portion between the connector 485 and the connector 472, it is difficult for water to enter from the connection portion. Further, since the waterproof member 650 covers the insertion port of the connector 472 into which the terminal of the electric wire 471 is inserted, it becomes difficult for water to enter from the insertion port.

As shown in FIG. 37, the through hole 41a of the motor housing 41 through which the wiring 470 passes may be closed by the waterproof member 660. This makes it difficult for water to enter the motor housing 41. The waterproof member 660 is made of, for example, a silicone resin. For example, the waterproof member 660 is formed by applying a silicone resin to the housing 41 so as to close the through hole 41a. In the example of FIG. 37, the fan 10A includes waterproof members 650 and 660, but does not have to include at least one of the waterproof members 650 and 660.

Further, the fan 10A may include at least one of the above-mentioned third to eleventh waterproof structures. Further, each electric wire 71 of the wiring 70 may be directly soldered to the control board 48. In this case, the solder connection portion between the electric wire 71 and the control board 48 may be covered with a waterproof member. Further, each electric wire 471 of the wiring 470 may be directly soldered to the control board 48. In this case, the solder connection portion between the electric wire 471 and the control board 48 may be covered with a waterproof member.

Further, in the fan 10A, as shown in FIG. 38, the jack connector 50 may be mounted on the control board 48. In this case, the connector 484 and the wiring 70 are not required, so that the assembly workability of the fan 10A is improved. The jack connector 50 is provided with, for example, a terminal for fixing, and is mounted on the control board 48 by soldering the terminal to the board 480. The method of fixing the jack connector 50 to the substrate 480 is not limited to this.

Also, the location of the control board 48 is not limited to the above example. For example, the control board 48 may be fixed to the outer surface of the motor housing 41. FIG. 39 is a diagram showing an example of how the control board 48 is fixed to the outer surface of the motor housing 41. In the example of FIG. 39, the control board 48 is fixed to the outer surface of the flat portion on the rear side of the cylindrical motor housing 41. In other words, the control board 48 is fixed to the surface of the wall portion 600 on the cover member 60 side. The jack connector 50 may be mounted on the control board 48 fixed to the outer surface of the motor housing 41.

When the control board 48 is fixed to the motor housing 41, when the control board 48 is replaced, the motor 40 also needs to be replaced. On the other hand, when the control board 48 is fixed to the cover member 60, it is not necessary to replace the motor 40 when replacing the control board 48. As a result, maintenance costs can be reduced.

In the above example, the wall portion 600 is composed of a part of the motor housing 41, but may be composed of a part of the housing 20. FIG. 40 is a diagram showing an example of how the wall portion 600 is composed of a part of the housing 20. In the example of FIG. 40, the housing 20 includes a housing recess (also referred to as a housing portion) 229 that houses the connector 50 and the control board 48 instead of the housing recess 223. The central portion of the back surface portion 220 of the housing 20 is recessed, and the accommodating recess 229 is formed in the central portion. The accommodating recess 229 has an opening surface 229a on the surface of the housing 20. The cover member 60 is attached to the back surface 220 of the housing 20 so as to cover the opening surface 229a.

In the example of FIG. 40, the control board 48 is fixed to, for example, the back surface 60a of the cover member 60. Similar to the above, the back surface 60a of the cover member 60 is provided with, for example, an annular waterproof member 110. The waterproof member 110 is located between the cover member 60 and the back surface portion 220. The control board 48 is located inside the annular waterproof member 110, as in FIG. 34 described above.

The accommodating recess 229 is, for example, a tubular accommodating portion with one end closed. The accommodating recess 229 includes a bottom portion 2290 and a tubular peripheral wall portion 2291 erected on the bottom portion 2290. The jack connector 50 is fixed to, for example, the bottom 2290. An insertion hole 2292 into which the plug connector 811 of the cable 810 is inserted is provided in the lower portion of the peripheral wall portion 2291. The plug connector 811 is inserted into the insertion hole 2292 of the housing 20 from the lower side of the jack connector 50, and then is inserted into the jack connector 50. The jack connector 50 may be mounted on the control board 48.

In the above example, the motor 40 was an inner rotor type motor, but in the example of FIG. 40, it is an outer rotor type motor. The motor 40 is not housed in the housing recess 229. The motor 40 includes a stator 42, a rotor 43, a motor shaft 44, and a bearing 45, but does not include a housing 41 and a bearing 46. The stator 42 and the bearing 45 are fixed to the housing 20. The stator 42 is located inside the rotor 43. The rotor 43 is fixed to the inner surface of the peripheral wall portion 321 of the tubular connecting portion 32 included in the blade portion 30. The rotor 43 is press-fitted into, for example, the inner space of the tubular connecting portion 32. The front end of the motor shaft 44 is fixed to the metal fitting 33 of the connecting portion 32 in the same manner as described above. When the rotor 43 rotates, the connecting portion 32 to which the rotor 43 is fixed rotates. In the example of FIG. 40, the tubular connecting portion 32 functions as a motor housing.

In the example of FIG. 40, the wall portion 600 that separates the arrangement space in which the control board 48 is arranged and the arrangement space in which the stator 42 and the rotor 43 are arranged is composed of the accommodation recess 229 of the housing 20. Also in the example of FIG. 40, since the wall portion 600 is provided, the waterproof measures for the control board 48 and the waterproof measures for the motor 40 can be taken individually. As a result, it becomes easier to take waterproof measures.

As described above, the garment with a fan 1 and the fan 10 have been described in detail, but the above description is an example in all aspects, and the disclosure is not limited thereto. In addition, the various examples described above can be applied in combination as long as they do not contradict each other. And it is understood that innumerable examples not illustrated can be assumed without departing from the scope of this disclosure.
