2. Description of the Related Art An electric fishing reel is provided with a spool drive motor for winding and driving a spool rotatably supported between side plates of a reel body. Japanese Patent Publication No. 59-15897 and Japanese Utility Model Laid-Open Publication No. 4-47967 are known. In these electric reels, a spool drive motor is disposed between both side plates at the rear or the front of the spool, and the driving force is transmitted to the spool via a speed reduction mechanism attached to the side plate.

[0003]

In the above-mentioned electric reel, a large amount of tensioned fishing line must be wound and driven by a weight, a tackle, a fish or the like in actual fishing. The conventional spool drive motor is arranged so as to be surrounded by the two side plates and surrounded by the spool, so that its heat dissipation is poor. Therefore, when a large amount of tensioned fishing line is driven to wind, it becomes easy to heat up. There are problems such as a decrease in motor performance and a decrease in winding efficiency. SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric fishing reel capable of improving the heat radiation of a spool drive motor and maintaining the motor performance for a long period of time.

In order to solve the above-mentioned problems, an electric reel for fishing according to the present invention comprises a spool drive motor for winding and driving a spool rotatably supported on a side plate of a reel body. Are arranged between the side plates of
The spool drive motor is housed in a motor case so as to form a closed space, and an inlet is formed in the motor case so that the closed space can be filled with a coolant.

[0005]

The spool drive motor for winding and driving the spool disposed between the side plates of the reel body is housed in the motor case so as to form a sealed space. An injection port is formed in the motor case, and a coolant can be filled in the closed space through the injection port. Heat generated when the spool drive motor is driven is cooled by the coolant filled in the closed space of the motor case, thereby preventing overheating of the motor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the accompanying drawings. 1 shows an example of an electric fishing reel, in which a driving force transmission mechanism is cut away, FIG. 2 is a side view of the electric fishing reel shown in FIG. 1, and FIG. 3 is a spool. It is a figure which expands and shows the part of a drive motor.

The reel body 1 comprises left and right frames 1a, 1b
These frames 1a and 1b are covered by side plates 2a and 2b, respectively. A spool 3 is provided between the left and right frames 1a and 1b via a spool shaft 3a.
Is rotatably supported by a bearing 5, and this spool is driven to be wound by a spool drive motor 7 or a manual handle 9 disposed between the frames 1a and 1b.

In this embodiment, the spool drive motor 7 is
As shown in FIG. 2, it is arranged in front of the spool 3 and is arranged in a cylindrical motor case 10 attached between the left and right frames 1a, 1b. Motor case 1
Numeral 0 has an internal space larger than the volume of the spool drive motor 7 housed therein, and forms a sealed space 12 with the spool drive motor housed. As will be described later, the space 12 can be filled with a coolant from the outside, and cools the heat radiation from the spool drive motor 7. Therefore, the airtightness of the space 12 is maintained at least to the extent that the cooling efficiency is not inferior.

The closed space 12 is formed such that the entire periphery of the spool drive motor 7 is filled with a coolant as shown in FIGS. 1 and 2 so that the spool drive motor 7 is sufficiently cooled. Is preferred. For this reason, the spool drive motor 7 is supported by the motor case at both ends of the drive shaft 7 a at a predetermined interval from the inner peripheral surface of the motor case 10, and is held in a state of being prevented from rotating by the detent screw 15. . A one-way clutch 16 is provided at one end of the drive shaft 7a.

An inlet 20 is formed in the motor case 10 so as to be exposed from the outer surface of the reel body 1, and a coolant can be filled into the closed space 12 from this portion. The coolant is a coolant mainly composed of, for example, ammonia, chlorofluorocarbon or the like. As shown by the dotted line in the figure, a commercially available spray type coolant is used. In addition,
The inlet 20 is configured so that once the closed space 12 is fully filled with the coolant, it is not filled any more.
Further, the motor case 10 has an exhaust port 22 through which the vaporized coolant in the closed space is discharged. This exhaust port is provided with a valve 22a made of rubber or the like so that the coolant vaporized in the enclosed space is discharged to the outside when the pressure exceeds a predetermined pressure. In this case, if a means (not shown) for visually confirming the discharge amount of the coolant is provided, it is possible to easily recognize the injection timing of the coolant.

As shown in FIG. 2, between the left and right frames 1a and 1b, the motor case 10 is provided in front of the spool 3.
A known fishing line guide device 25 is disposed above the left and right frames 1a, 1b in conjunction with the rotational drive of the spool 3.
By reciprocating between them, the fishing line is evenly wound around the spool 3. In addition, a display unit 27 is provided between the left and right frames 1a and 1b at a position where it can be easily seen, and displays the amount of fishing line released from the spool 3 and the like.
In this embodiment, a control means for calculating and processing the fishing line release amount, an external power supply connected to the spool drive motor 7, and the like are omitted.

The spool 3 is configured to be rotated by a winding drive of a spool drive motor 7 or a winding operation of a manual handle 9 as in the prior art, and provided on the left frame 1a and the right frame 1b, respectively. First gear reduction mechanism 30 and second gear reduction mechanism 50
The driving force is transmitted via. Hereinafter, the configuration of each of the gear reduction mechanisms 30 and 50 in this embodiment will be described.

The first gear reduction mechanism 30 includes the drive shaft 7
a is attached to the other end. The drive shaft 7a penetrates the cylindrical motor case 10 and protrudes toward the frame 1a, and is rotatably supported by the left frame 1a via a bearing 31. The sun gear 3 is provided on the motor drive shaft 7a.
The sun gear 32 is meshed with a plurality of planetary gears 33. Each of the planetary gears 33 meshes with an internal gear 35 provided on the inner periphery of the frame 1a, and is rotatably supported by a planetary gear support 38 that projects outward through a bracket 37. When the sun gear 32 rotates by the drive of the spool drive motor 7, each planetary gear 33 revolves while rotating, and rotates the planetary gear support 38 in one direction.

The tip of the planetary gear support 38 has a gear 4
The gear 40 is fixed to the gear 40, and the gear 40 is meshed with a gear 41 rotatably supported by the frame 1a. A gear 43 attached to an end of the spool shaft 3a is meshed with the gear 41, and the rotational driving force of the spool drive motor 7 is controlled by the gear reduction mechanism 30 and the gear 4
The power is transmitted to the spool shaft 3a via the first and third spools 43. Also,
As shown in FIG. 2, the drive gear 25a of the fishing line guide device 25 meshes with the gear 43 via intermediate gears 45 and 46 rotatably supported by the frame 2a. At the same time, the fishing line guide device 25 is reciprocally driven in conjunction with it.

The second gear reduction mechanism 50 is mounted on the opposite end of the spool shaft 3a. Spool shaft 3a
A sun gear 52 is attached to the opposite end of the sun gear 52, and a plurality of planet gears 53 mesh with the sun gear 52. Each of the planetary gears 53 meshes with an internal gear 55 engraved on one end of the spool 3 and a planetary gear support 58.
It is supported rotatably. This planetary gear support 58
Is rotatably supported by a spool shaft 3a via a bearing 59 by being fitted to a bracket 57 attached to the spool 3. The bracket 57 is rotatably supported by the right frame 1b via a bearing 60, whereby the spool 3 is rotatably supported between the left and right frames 1a, 1b via the spool shaft 3a.

A pinion gear 73 rotatably supported by a pinion shaft 71 disposed coaxially with the spool shaft 3a and supported movably in the axial direction is clutch-engaged with the planetary gear support 58. This clutch is turned on / off by moving a clutch plate 75 disposed between the planetary gear support 58 and the pinion gear 73 in the axial direction by a clutch lever (not shown).

The above-described manual handle 9 for winding the spool is attached to the distal end of a handle shaft 80 rotatably supported by the right frame 1b. The handle shaft is in mesh with the pinion gear 73. A drive gear 81 is rotatably mounted. A well-known braking device is disposed between the drive gear 81 and the handle shaft 80. By rotating the adjusting member 82, the rotational force of the manual handle 9 is adjusted and transmitted to the drive gear 81. . A ratchet 85 for preventing reverse rotation of the spool 3 is attached to the base end of the handle shaft 80.
When the spool drive motor 7 drives the spool 3 for winding, the handle shaft 80 does not rotate in conjunction with it.

When using the fishing electric reel having the above-described configuration, first, a coolant is injected into the closed space 12 of the motor case 10 through the injection port 20. As described above, the coolant is a coolant mainly composed of, for example, ammonia, chlorofluorocarbon or the like, and a commercially available spray-type coolant is used. FIG. 3 shows a state in which the closed space 12 is filled with a cooling medium.

When a fish hits during actual fishing, when the drive switch of the spool drive motor 7 (not shown) is turned on, the driving force is changed to the first gear reduction mechanism 30, the gears 41 and 43, The power is transmitted to the spool 5 via the spool shaft 3a and the second gear reduction mechanism 50. The fishing line that has been subjected to a high load by the caught fish or the like is evenly wound around the spool 3 via the fishing line guide device 25. Since the spool drive motor 7 performs the winding drive with a considerable load being applied, the spool drive motor 7 is overheated.
The coolant filled in 2 is forcibly cooled by depriving the motor heat and vaporizing.

As a result, a decrease in motor performance due to overheating of the spool drive motor 7 can be prevented, and the motor power can be sufficiently exhibited during actual fishing. And the closed space 12
The vaporized coolant inside is exhausted through the exhaust port 22 when the pressure exceeds a predetermined pressure. In addition, the coolant may be appropriately supplied to the closed space 12 of the motor case 10 in accordance with the conditions of the fishing ground.
It is possible to inject into.

On the other hand, the spool 3 can be wound up by the manual handle 9 without using the spool drive motor 7. In this case, the one-way clutch 16
The rotation of the spool shaft 3a is restricted by the action of the above, so that the rotational driving force by the manual handle is transmitted to the spool 3 via the second gear reduction mechanism 50 without applying a load from the motor side.

As shown in FIG. 4, a support shaft 9a perpendicular to the tip of the handle 9 is attached to the manual handle 9 in this embodiment, and a hollow structure integrally formed of resin with the support shaft 9a. Handle knob 9b is attached. An openable and closable cap 9c is formed on the handle knob 9b having a hollow structure, and an elastic locking piece 9d formed on the cap 9c is locked in a locking hole 9e formed on the main body of the handle knob 9b. As a result, the open state indicated by the dotted line is changed to the closed state as indicated by the solid line. To attach the handle knob 9b to the support shaft 9a, first, the handle knob 9b is fitted into the support shaft 9a, and a retaining ring 9f such as an E-ring is fitted into the tip of the support shaft 9a via a cap opening. This is performed by locking the handle knob 9b so that it can be rotated, and then closing the cap 9c. Thus, the handle knob 9 attached to the manual handle 9
By making b a hollow structure integrally formed of resin, the handle knob can be made light and inexpensive without holes or the like.
