DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of converting fish (bait fish) or fish caught as bait for fishing into water of a suitable temperature which has been cooled for a long period of time (that is, the temperature of the water rises). The present invention relates to a fish cooler box for supplying fresh air for keeping fish growing in the water.

[0002]

2. Description of the Related Art It is often used to provide a cooler box for fishing. However, depending on the type of fishing, a fish serving as a bait for catching a target fish may be used. There is a case where it is necessary to keep the bait fish fresh and keep it alive for a long time in the cooler box, or there is a case where you want to keep the fish caught alive and bring it back as a fresh fish That's why.

[0003] To this end, if water is previously put in a clar box, ice for cooling the water is put in, and fish is put in the cold water, the fish in the clar box is put in. Live a relatively long time.

[0004]

2. Description of the Related Art However, under the scorching sun, every time a bait fish is taken out of the crawler box or every time a caught fish is placed, the lid of the crawler box is opened. The fish in the cooler box often die as a result of warming, and there is a limit to keeping the fish in the cooler box alive for a long time.

[0005] This is an important problem for those who enjoy full-scale fishing, especially when a bait fish is put in a cooler box to catch a target fish. Because
When you need to find a desirable fishing spot, which takes time and when you find the best fishing spot,
Since the water in the cooler box has already warmed and fresh water [oxygen] has not been supplied to the water, the prey will die and become unsuitable as a prey. -There are many options.

[0006] Also, even if you search for a desirable fishing place,
If you have to prepare bait fish for fishing, you will need to find a store that sells bait fish, need time to return to the bait fish store, or if it is a kind of fish that can not be caught unless it is early. This can be very annoying because stores selling bait fish may not be open. In other words, depending on the purpose of fishing, it is necessary to purchase bait fish from the previous day, put the bait fish in the cooler box, and keep them, but the bait fish may die. In some cases, it may not serve its purpose as a bait fish.

[0007] Also, for purposes other than storage of bait fish, for example, when fish caught fresh are transported to a destination while being kept alive in a cooler box, and, for example, when a taste is desired, the cooler is used as described above. The fish in the box can be killed because the water in the box is already warm or the oxygen has not been supplied for a long time.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to prevent the temperature of water in a fish cooler box from rising for a long time, and to supply fresh air (oxygen) for fish to the water. The purpose of the present invention is to make it possible to keep the bait fish or the fish caught in the water in the fish cooler box for a long time.

[0009]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a peltier element 9 having one end of a heat conductive pipe 3 whose other end is immersed in water 2 in a fish cooler box 1. A heat sink 4 is provided on a heating surface opposite to the cooling surface side of the Peltier element 9 for radiating heat of the heating surface, and a heat sink 4 is provided on the heating surface of the heat sink 4. For fish
Fan motor 5 for dissipating outside of box 1
The heat conductive pipe 3 and the electromagnetic pump 7 are connected to each other, and the cool air generated on the cooling surface of the Peltier element 9 by the electromagnetic pump 7 is cooled through the heat conductive pipe 3 by the fish pump. -It can be achieved by providing a fish cooler box which is sent to the water in the cooler box 1 to prevent the temperature of the water 2 in the fish cooler box 1 from rising.

[0010] Another object of the present invention is to incorporate a cooling metal body 8 having good thermal conductivity made of a gas-permeable band or the like in the above-mentioned thermal conductive pipe 3 so as to be able to control fish. -It can be achieved by allowing the fish placed in the water 2 in the box 1 to be kept alive for a longer time.

[0011]

In the cover 6, a power supply battery (not shown) is built in or provided outside, and a power switch (not shown) is provided on the surface of the cover 6. When the power switch is turned on, power is supplied to the Peltier element 9 and also to the fan motor 5, so that the Peltier element 9 operates, the fan motor 5 rotates, and the electromagnetic pump 7 operates. I do.

The principle of the Peltier element 9 will be described later. When power is supplied to the Peltier element 9, the heating surface (upper part in the figure) is heated, and the cooling surface on the lower surface (in the figure). Lower part] is cooled.

When the fan motor 5 rotates, air is sucked through the through hole 10 of the cover 6 and is blown to the heat radiating fins 4a of the heat sink 4, and the wind passes through the heat radiating fins 4a and the heat storage press at the lower portion thereof. To dissipate the heat stored in the port 4b to the outside of the fish cooler box 1, that is, from the through hole 10 of the cover 6, so that the heat generated on the heating surface of the Peltier element 9 is sufficiently radiated. Since the cooling surface of the Peltier element 9 is cooled efficiently, cold air is formed on the lower surface of the thermally conductive metal lid 16 in contact with the cooling surface, and the cooled air on the lower surface of the lid 16 causes the thermally conductive pipe (heat pipe) to cool. Cool air is collected in the upper part of the inside of the metal pipe 3 (preferably a good metal pipe).

The electromagnetic pump 7 takes in air [oxygen] from the outside of the fish cooler box 1 through a through hole 10 formed in the cover 6 and connects the air to the electromagnetic pump 7. It continues to be fed into the heat conductive pipe 3 via a communication pipe (preferably a heat conductive metal pipe or a heat conductive synthetic resin) 17 formed of a vinyl tube or the like.

As a result, the cool air filled in the thermally conductive pipe 3 also cools the outer peripheral portion of the thermally conductive pipe 3 and the water 2 in the cooler box 1 in contact with the outer peripheral portion. , The temperature of the water 2 can be prevented from rising.

At the same time, the electromagnetic pump 7 takes in air [oxygen] from the outside of the fish cooler box 1 and continuously sends the air into the heat conductive metal pipe 3 through the communication pipe 17. The cool air on the lower surface of the lid 16, that is, the cool air on the upper part of the heat conductive pipe 3 is sent to the vinyl tube 18 connected to the lower part of the heat conductive pipe 3.
Cooler through foam 19 attached to the lower end of
It is supplied into water 2 in box 1 and cooler box 1
Not only does the temperature of the water 2 in the water 2 rise, but also fresh oxygen [air] required for the fish 20 in the water 2 is supplied.

In addition, since the cooling effect promoting metal body 8 made of a good heat conductor such as a metal scourer made of aluminum or the like is incorporated in the good heat conducting metal pipe 3, 3, the cooling effect of the air passing through the inside of the device 3 can be further enhanced.

If cool air continues to be supplied to the water 2 in the cooler box 1, the inside of the cooler box 1 will be filled with oxygen [air]. In this case, since a window (not shown) is formed in the cooler box 1, the window is opened or an escape portion for the supplied oxygen [air] is formed in an appropriate portion of the cooler box 1. Should be formed.

FIG. 1 is a longitudinal sectional view of a fish cooler box 1 according to one embodiment of the present invention, and FIG. An example of a method for forming the conductive pipe 3 is shown, and FIG. 3 and FIG.

Hereinafter, a fish cooler box 1 according to an embodiment of the present invention will be described with reference to FIGS.

The fish cooler box 1 has its cooler
A water storage unit 1a for storing water 2 for forming a box body, and a lid 1b for closing the upper opening end;
In the water storage section 1a, an amount of water 2 necessary for storing the fish 20 is stored. In this fish cooler box 1, the lid 1b
A through hole 21 for making a fishing bait box detachable is used. Therefore, at all times, a feed box (not shown) is attached to the through hole 21 and the cooler box 1
Is sealed.

In the fish cooler box 1 according to the present invention having such a structure, the bait box is first removed, and the air (oxygen) supply and cooling water producing unit described later is inserted into the removed through hole 21. 22 and the fish cooler box 1
Seal.

The air supply and cooling water production unit 22
First, due to the drawing of the through hole 21, the engaging projection (not shown) of the engagement attaching substrate 23 is engaged with the step of the through hole 21 for the same reason for engaging with the step (not shown). Engage the part.
On the lower surface of this substrate 23, a through-hole for installing the Peltier element 9 and the heat conductive metal cover 16 therein is formed.

On the upper surface of the engagement mounting board 23, a heat storage plate (a portion for storing heat on the heating surface side of the Peltier element 9 described later) 4b is provided with a radiation fin (heat storage plate). A heat sink 4 having a heat dissipating portion 4a is provided, and the heat sink 4 transfers the heat on the heating surface side of the Peltier element 9 transmitted to the heat dissipating fins 4a. A fan motor 5 for dissipating the radiation outside the box 1 is provided. In addition, this fan motor 5
It is preferable to use a DC (direct current) brushless axial fan motor which is most commercially available, easily available, and can be driven by a battery.

The engagement mounting substrate 23 of the heat storage plate 4b
The heating surface side of the Peltier element 9 is bonded to a portion facing the through hole formed by using a heat conductive adhesive or the like.

One end (upper end) of the heat conductive pipe 3 is attached to a lower portion of the engagement mounting substrate 23 by an appropriate means so that the Peltier element 9 is accommodated within the inner diameter thereof. As this material, it is best to use a material with good thermal conductivity, so it is better to use one made of aluminum or its alloy, but it is not limited to this, but in any case, It is formed using a good material.

In order to enhance the cooling effect, the inside of the heat conductive pipe 3 may be formed with a projection that expands in the inner diameter direction, may be formed in a spiral air passage, or may have a lamination gap. However, since the cooling effect of the water 2 can be enhanced, such a method may be employed. However, here, a commercially available metal band-shaped scourer made of aluminum, iron, copper, iron or the like is embedded. are doing. A metal scourer is the most suitable as such a cooling effect promoting metal body 8 because air can pass through it. Even in an experiment, such a metal scourer is placed inside the above-mentioned thermally conductive pipe 3. Good results have been obtained when buried.

Therefore, a cooling effect promoting metal body 8 made of a gas-permeable band such as a commercially available metal band-like scallops made of aluminum or an alloy thereof is built in the heat conductive pipe 3. I have.

The thermally conductive pipe 3 having the cooling effect promoting metal body 8 made of the above-mentioned air-permeable strip or the like is provided with:
The upper and lower open ends are formed of a cylindrical main body 3a, and the inner periphery of the upper and lower open ends thereof are threaded, and the thermally conductive metal lids 16 and 24 having screw portions to be screwed with the screws are used to cover the upper and lower open ends. It is closed.

The thus formed thermally conductive pipe 3 whose both ends are closed by the thermally conductive metal lids 16 and 24 has the thermally conductive metal lid 16 in contact with the cooling surface side of the Peltier element 9. When the power switch (not shown) of the power supply battery (not shown) inside or outside the cover 6 is turned on, the cooling surface of the Peltier element 9 is cooled. Cold air is formed on the lower surface of the metallic cover 16 and the cover 1
By the cool air on the lower surface of 6, cool air is stored in the upper part in the heat conductive pipe 3.

Here, the principle of the Peltier element 9 will be described.
This will be briefly described below with reference to FIGS.

FIG. 3 shows a couple of the Peltier element 9,
FIG. 4 shows a Peltier device 9 formed by combining the couples of FIG.

Referring to FIG. 3, the case where the heat sink 4 (heat storage plate 4b) is cooled by the couple of the Peltier element 9 will be described. A cold junction for heat absorption is provided by a heat junction. The heat sink 4 (heat storage plate 4b).

Here, the power switch (not shown) of the DC power supply 11 (corresponding to a power supply battery built in the cover 6 or provided outside thereof) is turned on, and the electric conductor 12 of the Peltier element 9 is turned on.
When current flows through the heat sink 4, the heat sink 4 (heat storage plate 4b)
In some parts, as electrons flow from one semiconductor to another, they will transition from a low energy state to a high energy state, where the energy is absorbed by the electrons in the form of heat.

A power supply 11 supplies energy for causing the flow of electrons, and a heat sink 4 made of, for example, aluminum or magnesium, which has excellent heat conductivity and serves as a hot junction, is used as a fan motor. 5 (DC brushless axial fan motor) releases extra heat to the outside.

As described above, the Peltier element 9 is a solid-state heat pump, does not use any liquid or gas, and has no moving parts. There is.

In FIG. 3, reference numerals 13-1, 13-
Reference numeral 2 denotes a bismuth telluride semiconductor, which is composed of two types of elements, an excess electron N-type (N-type semiconductor) 13-1 and an insufficient electron P-type (P-type semiconductor) 13-2 due to impurity doping. I have. Reference numeral 14 denotes an electric insulator such as alumina ceramics, and 15 denotes a direction in which a carrier current and a heat flow flow.

That is, the Peltier element 9 has an excess electron N-type (N-type semiconductor) 13-1 and an insufficient electron P-type (P-type semiconductor)
13-2 is joined by a metal piece, that is, an electric conductor 12, and the DC current of the DC power supply 11 is changed from excess electron N-type (N-type semiconductor) 13-1 to insufficient electron P-type (P-type semiconductor) 13-2.
In the excess electron N-type (N-type semiconductor) 13-1, the insufficient electron P-type (P-type semiconductor) 13
At -2, heat is transferred in the forward direction, and the cooling surface of the heat sink 4 (heat storage plate 4b) is cooled, and heat is taken from the surroundings. When the heat of the electric conductor 12 on the high temperature side, that is, on the axial fan motor 5 side is efficiently radiated by the heat radiation fin 4a, the heat is continuously pumped from the low temperature side to the high temperature side.

As described above, the heat generated by the heat sink 4 (heat storage plate 4b) serving as a cold junction is pumped to the heat sink 4 serving as a hot junction. It is proportional to the carrier current flowing through the circuit and the number of couplers.

Therefore, the Peltier element 9 actually used is
Is a module combining the couplers of FIG. 3 as shown in FIG. 4, and is electrically connected in series and thermally connected in parallel.

Since power is supplied to the Peltier element 9 and, at the same time, power is also supplied to the fan motor 5, the fan motor 5 rotates and sucks air from the through hole 10 of the cover 6, and heats the air. The air is blown to the radiation fins 4a of the sink 4 and the wind passes through the radiation fins 4a, and the heat storage plate 4 under the radiation fins 4a.
b to the outside of the fish cooler box 1
That is, since the heat is radiated from the through hole 10 of the cover 6, the heat generated on the heating surface of the Peltier element 9 is sufficiently radiated.

At the same time, since the Peltier element 9 operates and the electromagnetic pump 7 operates, the electromagnetic pump 7 has a pipe through hole, and a pipe is mounted in the pipe through hole. One end of the vinyl tube 18 is connected to the other end, and the other end is connected to and communicated with the thermally conductive pipe 3, so that cool air is continuously fed into the thermally conductive pipe 3.

As a result, the cool air filled in the thermally conductive pipe 3 also cools the outer peripheral portion of the thermally conductive pipe 3 and cools the cooling effect promoting metal body 8 in the thermally conductive metal pipe 3. A cooler that passes through the outer peripheral portion to enhance the cooling effect of air
Since the water 2 in the box 1 is cooled, the temperature of the water 2 can be prevented from rising.

As described above, the electromagnetic pump 7 takes in the air [oxygen] from the outside of the fish cooler box 1 and continuously sends the air into the heat conductive metal pipe 3 through the communication pipe 17. Therefore, the cool air on the lower surface of the lid 16, that is, the cool air in the upper portion of the thermally conductive pipe 3 is connected to a tube provided on the thermally conductive metal lid 24 at the lower portion of the thermally conductive pipe 3 by connecting one end to a vinyl tube. To the water 2 in the cooler box 1 through a foam 19 attached to the other end (lower end) of the vinyl tube 18. In addition to preventing the temperature of the water 2 in the water 2 from rising, fresh oxygen [air] required for the fish 20 in the water 2 is also supplied.

An engaging cylinder 25 is rotatably provided on the outer periphery of the upper end of the heat conductive metal pipe 3. An engaging flange 25a is formed at the upper end of the engaging cylinder 25,
By turning 5, the flange 25a comes out of the through hole 21 or engages with the lid 1b, so that the air (oxygen) supply right cooling water producing unit 22 can be detached from the lid 1b. I do. Since this mechanism is not the purpose of the present invention, a detailed description is omitted.

[0046]

As described above, the fish cooler box of the present invention differs from the conventional simple cooler box in that the water inside is cooled and preserved for a short time. As a result, the water inside the water is kept cold for a long time at the required time. As a result, the temperature of the water can be prevented from rising, and the life of the fish in the water can be extended. Therefore, it is possible to construct a new one that completely satisfies the demands of the conventional fishing maniacs, and also has an advantage that an extremely useful one that solves the conventional disadvantages described above can be configured at a low cost.
