As disclosed in Japanese Patent Application Laid-Open No. 4-16216, various motor burnout prevention devices for preventing burnout of a spool drive motor in this type of electric fishing reel have been proposed.

In the motor burnout prevention device disclosed in Japanese Patent Application Laid-Open No. 64-21616, a temperature sensor is attached to a spool drive motor housed in a motor case of a reel body, and the temperature of the spool drive motor reaches a set temperature. Sometimes, power supply to the spool drive motor is stopped.

[0004]

However, since the spool drive motor mounted on the reel body requires a waterproof structure depending on the use environment of the fishing spot, it is not possible to mount the temperature sensor directly on or near the spool drive motor. It is difficult in terms of waterproofness, and in the case of an electric fishing reel in which a spool drive motor is built in the spool, the spool itself may rotate, so the temperature sensor is attached to the spool drive motor itself or in the vicinity thereof. It was pointed out that this was even more difficult.

The present invention has been devised in view of the above circumstances. In order to sufficiently exhibit the performance of a spool drive motor by temperature management by a temperature sensor, the mounting position of the temperature sensor on the reel body is changed by changing the position. It is an object of the present invention to provide an electric fishing reel in which the attachment property is improved and the spool drive motor is prevented from being burned out by temperature management by the temperature sensor.

A temperature sensor directly attached to the switching element,
The set temperature set as the temperature at which the spool drive motor is in danger of burning is compared with the temperature detected by the temperature sensor. When the detected temperature reaches the set temperature, the switching element
The power supply to the spool drive motor is stopped by issuing an OFF command to stop the power supply when the detected temperature falls to the reset temperature.
And a control unit for removing the control signal.

[0007]

[0008]

According to the first aspect of the present invention, the control means compares the set temperature with the detected temperature from the temperature sensor, and when the detected temperature reaches the set temperature, the power supply to the spool drive motor is stopped and the spool drive motor is stopped. Prevent burnout of drive motor. The control means determines that the temperature detected by the temperature sensor is the return temperature.
When it drops to below, the suspension of power supply is released.

A clutch plate is provided between the pinion gear 41 and a boss portion 31a of the gear carrier 31 opposed thereto. 45 are attached.

The clutch plate 45 is a component of a clutch for transmitting / cutting off the winding power from the spool drive motor 7 to the spool 9, and is operated by a clutch motor built in the reel body 1 like a conventional clutch.
That is, the control box 46 mounted on the upper part of the reel body 1
On the operation panel 47, a clutch switch 49 for switching the clutch between ON and OFF is provided. When the clutch switch 49 is operated, for example, when the fishing line is paid out, as shown in FIG. 3, the clutch motor 53 is driven by a command from the control means 51 which has input the signal, and the clutch motor 53 The activated clutch plate 45 releases the engagement between the pinion gear 41 and the boss portion 31a of the gear carrier 31 (clutch OF

Further, the motor output of the spool drive motor 7 is continuously increased and decreased in front of the side portion of the side plate 5 in the same manner as the electric fishing reel disclosed in Japanese Patent Application No. 3-324492 by the present applicant. An adjustment lever 63 for changing the rotation speed is attached so as to be rotatable over a predetermined range. The adjustment lever 63 is connected to a potentiometer 65 built in the side plate 5. Then, as shown in FIG. 3, a change in the resistance value of the potentiometer 65 due to the operation of the adjustment lever 63 is input to the control unit 51, and the control unit 51 sets the duty ratio of the pulse signal according to the displacement amount of the adjustment lever 63. The rotational speed of the spool drive motor 7 can be continuously changed from zero to the maximum speed by variably controlling the motor drive current conduction time ratio by a switching element (power mos) 67 connected to the switching power supply circuit of the spool drive motor 7. It has become.

The digital display 61 is provided with a motor output display section 61a for displaying the motor speed by operating the adjustment lever 63, and the bar display amount of the motor output display section 61a according to the adjustment of the motor speed. The scale of is changed sequentially. The reel body 1
Is connected to a battery 71 and a ship power supply via a power cord (not shown), and
The ON operation of the / OFF switch 73 activates the spool drive motor 7, the control means 51, the clutch motor 53 and the like.

The electric reel for fishing according to the present embodiment has the same structure as the conventional one as described above, and has the above-mentioned switching for the purpose of preventing the spool drive motor 7 from burning out by controlling the temperature with a temperature sensor. The temperature sensor 75 is directly attached to the element 67. That is, as described above, the spool drive motor generally mounted on the reel body is required to have a waterproof structure depending on the use environment of the fishing ground. Therefore, mounting the temperature sensor directly on or near the spool drive motor is waterproof. In addition, in the case of an electric fishing reel having a spool drive motor built in the spool, the spool itself may rotate, so that the temperature sensor may be attached to the spool drive motor itself or in the vicinity thereof. It was difficult.

Therefore, in the present embodiment, the switching element 67
To which was attached a temperature sensor 75 directly, since the switching devices 67 are typically screwed to the reel body 1, directly taking the temperature sensor 75 to the switching devices 67
The attachment is extremely easy as compared with the case where a temperature sensor is attached to the spool drive motor 7 built in the spool 9. The temperature signal detected by the temperature sensor 75 is input to the control means 51 via an amplifier (not shown). The control means 51 has a spool drive motor corresponding to the temperature of the switching element 67 itself. 7 burning hazardous area temperature consider as setting temperature settings are stored, the control unit 51 such a set temperature and the temperature sensor 75
Comparing the detected temperature from, when the detected temperature has reached the set temperature, and is so that stopping the power supply to the spool drive motor 7 issues a OFF command to the switching devices 67.

The above-mentioned set temperature is set in advance by calculating the correlation between the temperature rise of the spool drive motor 7 and the temperature of the switching element 67 by experiment.
When the limit temperature of the spool drive motor 70
When the temperature of the device rises to 70 ° C., the switching element 67
If the temperature rises to 100 ° C, set the temperature to 10
When the temperature is set to 0 ° C. and the temperature of the switching element 67 decreases to 90 ° C., the power supply to the spool drive motor 7 is restored. As shown in FIG. 1, the digital display 61 is provided with a power supply stop display section 61b. When the temperature detected by the temperature sensor 75 reaches the set temperature, the control means 51 turns off the switching element 67. A power supply stop is displayed on the power supply stop display unit 61b when a command is issued, and when the switching element 67 drops to a return temperature of 90 ° C., the display of the power supply stop is released.

The above-mentioned temperature sensor 75 is also ON / O
When the FF switch 73 is turned on, it starts up together with the spool drive motor 7 and the control means 51. The electric fishing reel according to the present embodiment is configured as described above. Next, the operation thereof will be described with reference to the flowchart of FIG. In fishing, when the battery 71 is connected to the reel body 1 and the ON / OFF switch 73 is turned on (step 1), the spool drive motor 7, the control means 51, the clutch motor 53 and the like are activated (step 2).

When the clutch is switched off by operating the clutch switch 49, the spool 9 is in a free state (clutch OFF), so that the fishing line is paid out of the spool 9 by the weight of the device, and the rotation of the spool 9 is reduced. The pulse is converted by the encoder 59 into a pulse corresponding to the payout length of the fishing line, input to the control means 51, and calculated. And
The feed yarn length based on the calculation result is displayed on the digital display 61.
Is displayed, the fisherman may operate the clutch switch 49 to switch the clutch ON at a predetermined water depth while watching the display.

In this state, wait for the fish to hit. Then, when the fish hits, the angler will display the motor output display section 61.
If the output of the spool drive motor 7 is controlled by operating the adjusting lever 63 according to the situation while checking the value a, the fishing line is wound up at a speed corresponding to the output. And
To stop the winding, the adjustment lever 63 may be returned.

As the fishing is performed by driving the spool drive motor 7, the temperature of the spool drive motor 7 and the switching element 67 rises.
Simultaneously with the operation of the FF switch 73, the temperature sensor 75 detects the temperature of the switching element 67, and the control means 51 compares the temperature information detected by the temperature sensor 75 with the set temperature, so that the temperature of the switching element 67 becomes the set temperature. , That is, whether the temperature of the spool drive motor 7 has reached the burnout danger zone (step 3).

If the temperature of the switching element 67 reaches the set temperature due to continuous use for a long time, step 3
When the control means 51 determines that the switching element 67
, The power supply to the spool drive motor 7 is stopped (step 4), thereby preventing the spool drive motor 7 from burning. At the same time, the control means 51 displays a power supply stop on the power supply stop display section 61b.

When the power supply to the spool drive motor 7 is stopped and the spool drive motor 7 is stopped, the temperature of the switching element 67 gradually decreases. Then, it is determined whether or not the temperature of the switching element 67 has decreased to the above-mentioned return temperature based on the temperature information. Then, when the temperature of the switching element 67 decreases to the return temperature, in step 6, the control means 51 issues an ON command to the switching element 67 to restore the power supply to the spool drive motor 7, and at the same time, the power supply stop display section. Since the indication of the stop of the power supply at 61b is released, the angler can operate the adjustment lever 63 again to allow the spool drive motor 7 to wind up.

Then, to end the fishing, ON / OFF
The switch 73 may be turned off. As described above, according to the present embodiment, similarly to the conventional electric fishing reel equipped with the motor burnout prevention device disclosed in JP-A-64-16216, the spool drive motor is controlled by the temperature sensor 75 for temperature control. 7 of performance it is possible to sufficiently exhibit, Thus also, according to this embodiment, the reel body
For mounting the temperature sensor 75 directly to the switching devices 67 to be secured to one, compared with the conventional example of attaching the temperature sensor to the spool drive motor built in the spool directly be attached easily Wamete can the temperature sensor 75 It has become possible.

In the above embodiment, the spool drive motor 7
The present invention is suitable for an electric reel for fishing in which
It was used, for example, Japanese Utility Model No. 7-25766
Spool, like the electric reel for fishing disclosed in
An electric lead with a drive motor located in front of and behind the spool
Needless to say, the present invention can be applied to a computer.

Further, in order to protect the spool drive motor by controlling the energization of the spool drive motor, the present applicant disclosed in Japanese Patent Application Laid-Open No. 7-50963 a current for detecting the current value of the spool drive motor. A detecting means, a breaker for interrupting an electric circuit of the spool drive motor, and a timer for measuring a continuous or intermittent energizing time for each preset motor current specified value, and accumulating the respective energized times, and setting each motor current specified When the breaker operating conditions set in advance by the cumulative value of the values and the energizing times thereof match the breaker operating conditions, the breaker is operated to stop the spool drive motor, while the current value detected by the current detecting means is the current of each motor. When it is lower than the specified value, the energization time is measured by a timer, and this is calculated from the cumulative energization time of all motor current specified values measured and accumulated by the timer. An electric fishing reel provided with a control means for calculating the angle of the spool is disclosed. However, even if the present invention is applied to such an electric fishing reel and the breaker operating condition is met, the burnout risk area of the spool drive motor is reduced. If the switching element has not risen to the temperature, the spool drive motor may not be stopped.

Thus, according to the fishing electric reel, it is possible to prevent the spool drive motor from burning out while taking the performance of the spool drive motor to the utmost. Conventionally, a lead-acid battery (battery) or a ship power source (power generation by engine rotation) has been used as a power source for the electric fishing reel as in the above-described embodiment. It has been pointed out that as the output of the reel is increased, a larger one is required and it is difficult to carry.

Further, in the case of the ship power supply, there is a problem that the voltage fluctuates greatly depending on the engine speed and adversely affects the control means (microcomputer) of the electric fishing reel. Therefore, if a small battery (for example, a lead storage battery, a lithium secondary battery, or a Ni-hydrogen secondary battery) that can be charged using a ship power supply is prepared at about 2 Ah, there is no need to carry a heavy battery, A stable voltage can be supplied to the reel, and the microcomputer is not adversely affected.
