Description

Description: TECHNICAL FIELD The present invention relates to an electric reel with a charging function.

(Background Art) A battery is used as a means for supplying electric power to a motor of an electric reel, an electronic circuit, and the like. These batteries are required to be reusable. Therefore, it is necessary to charge the battery after use, and the battery is charged by supplying power from a commercial power source or a battery of an automatic operator via a dedicated charger.

(Problems to be Solved by the Invention) However, the above-described conventional method of providing a dedicated charger has the following problems.

First, there is a problem that a special charger must be prepared. In addition, the present inventor proposes a battery in which a rechargeable battery (eg, nickel-cadmium battery) is housed in a battery box attachable to the reel body as a power supply battery for the electric reel, separately from the present invention. However, when charging with a dedicated charger, there is a problem that the battery box must be removed from the reel body one by one, which is troublesome.

Accordingly, an object of the present invention is to provide an electric reel with a charging function that incorporates a charger in order to eliminate the need for a dedicated charger when charging a power supply battery of the electric reel.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, an input terminal for receiving power from the outside, an output terminal for transmitting power to the battery to be charged, and the input terminal and the output terminal are connected to monitor the voltage value of the battery during charging and It is characterized by comprising charge control means for interrupting conduction between the input terminal and the output terminal when the voltage reaches a predetermined voltage value.

(Action) The action will be described.

By providing the electric reel with the charge control means, the battery can be charged by electric power taken in from the outside, and the battery can be charged without a dedicated charger.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

 First, the configuration will be described.

Reference numeral 12 denotes an input terminal, which is provided on the electric reel 10 body. The input terminal 12 has a step-down (eg, DC15V) power from a commercial power supply 30 (100 VAC) through the rectifier transformer 14,
Alternatively, power can be received from a battery 18 (for example, DC 12 V) of the automobile 16 via a cigarette lighter socket or the like.

Reference numeral 20 denotes an output terminal, which is also provided on the electric reel 10 body. The output terminal 20 also serves as a terminal for supplying power from the power supply battery 22 of the electric reel 10 to the electric reel 10. The battery 22 is a rechargeable battery (eg, nickel-
A cadmium battery is accommodated in a battery box (not shown) and can be attached to the electric reel 10 body. In addition,
When the battery box is mounted on the main body of the electric reel 10, the output terminal 20 and the terminal (not shown) of the battery 22 are electrically connected.

Numeral 24 denotes a charging circuit, which is a circuit for transmitting the electric power input from the input terminal 12 to the battery 22 from the output terminal 20. Switching control is performed by a CPU (Central Processing-ssing Unit) described later. When the charging circuit 24 operates, the power supply from the battery 22 to the electric reel 10 via the output terminal 20 is stopped, and the battery 22 can be supplied with charging power from the output terminal 20.

Reference numeral 26 denotes a CPU, which is composed of a microprocessor and an IC memory. The control operation will be described in detail later. After detecting the start of charging, the switching of the charging circuit is controlled to monitor overcharging of the battery 22. The CPU also controls the operation of the motor and other parts.

Reference numeral 28 denotes a timer including a counter, which measures a charging time in response to a clock pulse from the CPU
Send to U26. Timer 28 is also provided for battery 2
This is to prevent overcharge of 2.

The charging circuit 24, the CPU 26, and the timer 28 constitute a charging control unit.

Next, the operation of the electric reel 10 configured as described above will be described.

When the battery 22 housed in the battery box (not shown) is attached to the main body of the electric reel 10 (the output terminal 20 and the terminal of the battery 22 are connected), the input terminal 12
When power is supplied to the input terminal 12, the CPU 26 detects that a voltage has been applied to the input terminal 12, determines that charging has started, and clears and starts the timer 28.

At that time, the CPU 26 determines whether the charging power source is the commercial power source 30 or the automobile 16
It is determined whether the battery 18 (may be a ship). This determination is made when the power is supplied from the commercial power supply 30.Since the current value is small and stable, continuous charging can be performed.
In the case of the battery 18 of the automobile 16, since the current value is large, if the continuous charging is performed, the large current battery 22 may be burned out. Therefore, the intermittent charging is performed at appropriate time intervals (determined by the capacity of the battery 22 or the like). This is because there is a need. Whether the charging power source is the commercial power source 30 or the battery 18 of the vehicle 16 is determined based on the initial voltage applied to the input terminal 12 detected by the CPU 26 at the time of starting charging. In the case of the battery 18 of the car 16,
Since the load is about 14 volts with no load, if the voltage at the time of no load from the commercial power supply 30 is set to 15 volts or more with the rectifier transformer 14, the CPU 26 determines the charging power supply based on the magnitude of the initial voltage (no load voltage). It is possible to determine whether to perform continuous charging or intermittent charging.

In the case of continuous charging, the CPU 26 charging circuit 24 is continuously turned on. On the other hand, in the case of intermittent charging, the CPU 26 turns on the charging circuit 24 intermittently at predetermined time intervals (eg, a duty ratio of 10%). When the charging circuit 24 becomes conductive, a charging voltage appears at the output terminal 20 to charge the battery 22.

During charging, the CPU 26 checks the voltage of the battery 22 at predetermined time intervals (which may be arbitrarily determined), stores the voltage in the IC memory, and compares the current voltage with the previous voltage. Battery 22
Since the voltage rises during charging, the voltage reaches a peak when it reaches full charge, and then falls, the CPU 26 determines that the current voltage is lower than the previous voltage and determines that the battery is fully charged, and the charging circuit 24 Of the battery 22 to prevent overcharging. On the other hand, from timer 28 to CP
The charging time data is constantly sent to U26. The CPU 26 does not attempt to prevent overcharging only by looking at the voltage of the battery 22. Even when the CPU 28 detects that the measured value of the timer 28 has reached 2 hours from the start even if it is not determined that the battery 22 is fully charged, The conduction of the charging circuit 24 is cut off to stop charging. Overcharging of the battery 22 is prevented by the double check by the battery voltage of the CPU 26 and the timer.

Note that the CPU 26 determines whether the battery 22 is fully charged or the timer 28 is fully charged.
When the elapse of time is determined, the user may be notified of the completion of charging by means such as a buzzer or LED blinking (not shown).

When the charging is completed, the user disconnects the input terminal 12 from the charging power source and can immediately use the electric reel 10 with the battery box attached. In order to prevent a short circuit, it is preferable to take appropriate waterproofing measures for the input terminal 12 and the output terminal 20.

As described above, various preferred embodiments of the present invention have been described. However, the present invention is not limited to the above-described embodiments. For example, it is not necessary to measure the elapsed time using a timer. Of course, many more modifications can be made without departing from the scope of the invention.

(Effect of the Invention) When the electric reel with a charging function according to the present invention is used, since a charger is built in the electric reel main body, it is not necessary to prepare a special charger when charging the power supply battery. Since the operation can be performed with the battery mounted on the electric reel, the operation procedure is simple and the operation can be efficiently performed.
