It relates to a delivery bag having a.

In general, the food made in the restaurant and delivered to each home is cooled in the delivery process there is a problem that the taste of the food falls.

For example, fast foods such as pizza and chicken had to be eaten right after cooking due to the nature of the food. However, if you make pizza or chicken and deliver them to your home, the pizza or chicken will cool and taste. It was not there.

As a means to solve this problem, the Republic of Korea Utility Model Registration No. 20-443498 (Published Date 2009.2.18) has been disclosed. According to this prior art, by installing a heat generating member that generates heat by receiving power (AC) from the outside on the inner bottom of the pizza bag, by supplying power to the heat generating member provided in the pizza bag before delivery of the pizza by the heat generating member After raising the temperature inside the pizza bag, the pizza was put in the pizza bag, the power line was disconnected to cut off the power supply, and the pizza was delivered. Thus, the inside of the pizza bag heated by the heating member was able to prevent the pizza from cooling during delivery to the home.

However, such a pizza bag according to the prior art cuts off the power supplied to the heating element and at the same time the temperature of the heating element begins to fall, while the pizza temperature drops sharply during delivery of the pizza to the home warm pizza to the customer Could not be supplied.

That is, the pizza bag according to the prior art heats the heating element only when connecting the connection line of the power supply device installed in the restaurant to the pizza bag, and after the connection line is separated, since the inside of the bag is heated only by the residual heat of the heating element, As the problem progressed, the pizza deliveryman caused the motorcycle to run at high speed, which caused problems such as traffic accidents and stress. In addition, the bag was old or contaminated, and the bag had to be replaced every six to 12 months. This caused a bag replacement cost, and the hygiene was poor because the heating member was fixed to the bag and the bag could not be washed. There was this.

On the other hand, Korean Utility Model Registration No. 20-0435658 (published: 2007.02.08) discloses a food insulation system using a battery of a motorcycle. The food insulation system is configured to keep food warm by using a battery of the motorcycle as a power source after installing a temperature-keeping means inside the money box provided on the motorcycle. However, since the food insulation system uses the battery of the motorcycle, it is difficult to use the battery when the battery is discharged, and there is a problem that the temperature of the food drops sharply after removing the food from the box installed in the motorcycle. In particular, in winter, the temperature of the food drastically decreased, so that foods such as pizza could not taste properly.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

In the accompanying drawings, Figure 1 is an exploded perspective view showing a delivery bag according to the present invention, Figure 2 is a plan view showing a delivery bag shown in Figure 1, Figure 3 is a combined state of the delivery bag shown in Figure 1 It is a cross section.

As shown in Figures 1 to 3, the delivery bag 10 having a heat generating function using a DC power source according to the present invention is a storage space 14 that can accommodate food, and opening and closing the storage space 14 The cover 16 is provided at the inlet of the storage space 14, the main body 12 having the handle 18, and the heat generating member 20 provided at the bottom of the storage space 14.

This will be described in more detail.

A heat generating member accommodating part 17 for accommodating the heat generating member 20 is formed at a bottom of the accommodating space 14 of the main body 12, and a charging jack protrudes to the outside on one side of the heat generating member accommodating part 17. The through hole 19 is formed, and the inlet of the heat generating member accommodating part 17 is opened and closed by a zipper or a Velcro tape.

With this structure, a diaphragm 17A made of a woven material or a metal thin plate having good thermal conductivity is provided between the storage space 14 and the heat generating member accommodating portion 17. In the present embodiment will be described on the basis of being composed of a thin fabric material. Thus, when the diaphragm 17A provided between the storage space 14 and the heat generating member accommodating portion 17 is made of a thin fabric material or a metal thin plate having good thermal conductivity, the heat generated from the heating wire 26 is not lost. It is to be conducted to the food settled in 14).

The heat generating member 20 is for generating heat by a series power source supplied from the secondary battery 30 in the heat generating member accommodating part 17, and the plate-shaped first heat insulating material 22 having a plurality of pores 22A. At least one plate-shaped second heat insulating material 24 laminated on the top surface of the first heat insulating material 22, a heat storage material 25 laminated on the top surface of the second heat insulating material 24, and the heat storage material 25 A heating wire 26 wired on the upper surface, a metal thin plate 28 for diffusing heat generated from the heating wire 26, and electrically connected to the heating wire 26 so as to supply a DC power to the heating wire 26. , The first and second heat insulating materials 22 and 24 and the heat storage material 25 is formed thinner than the total thickness of the laminated plate-shaped secondary battery provided in the first and second heat insulating materials 22 and 24 and the heat storage material 25 30 and a control unit 40 for controlling the power supply of the secondary battery 30 to be selectively supplied to the heating line 26. The heat generating member 20 is formed in a plate shape having a predetermined thickness as shown in FIG. This is to facilitate storage in the heat generating member accommodating portion 17 to be described later, and to occupy less space.

The first insulating material 22 has a structure in which a plurality of pores 22A are formed between upper and lower plates, and is made of a material having low thermal conductivity such as urethane or plastic. This is to prevent heat generated from the heating wire 26 from being discharged to the outside (bottom of the heat generating member accommodating portion) and being lost, and to prevent external cold air from entering. In other words, each of the pores to block the heat conduction to minimize or block the heat loss.

The second heat insulating material 24 is laminated and attached to the upper surface of the first heat insulating material 22, and is made of a material having a function of blocking heat, such as polyethylene or urethane. In addition, the heat loss of the heat storage material 25 laminated on the upper surface is minimized by being made of a structure and a material such as a sponge. In other words, the heat of the heating wire 26 is minimized to the outside through the heat storage material (25).

The heat storage material 25 is composed of a heat storage urethane foam having a close cell structure, which is an excellent heat storage structure, not an open cell, which is a general urethane structure. The heat storage material 25 is to minimize the heat loss of the heating wire 26, to accumulate heat, and to have a soft elasticity itself to protect the heating wire 26 is wired on the upper surface.

The first and second insulating materials 22 and 24 are bonded and bonded in a laminated state by a special acrylic adhesive (indirect heat resistance of 150 ° C.). The heat storage material 25 described above is bonded to the second heat insulation material 24.

The heat generated from the heating wire 26 by the first and second heat insulating materials 22 and 24 described above is prevented from being discharged to the bottom of the bag 10. That is, the phenomenon of being discharged to the bottom of the heat generating member accommodating part 17 and being lost is minimized or prevented.

The heating wire 26 is made of microfiber filaments having a thickness of 4 to 30 µm, and is manufactured by specially processing a special alloy. These microfiber filaments can be utilized as a thin and soft electric heating element, which is to prevent static electricity due to the properties of electrical conductivity, heat resistance, high strength.

The microfiber filaments are made of a microfiber alloy composition. The microfiber alloy composition is composed of 12 ~ 15% of nickel (Ni), 16 ~ 18% of chromium (Cr) and 2.0 ~ 3.0% of molybdenum (Mo). Yarn having a diameter can be extracted, and it is preferable to use the drawing method to obtain a uniform diameter. Fibers extracted from cutting and melting methods have different diameters in yarns of the same length, making it difficult to match accurate resistance values, and thus, temperature deviations occur at the same length, making uniform temperature specifications difficult. Yarn, an exothermic resistance wire extracted by the above-mentioned drawing method, obtains a resistance value required by combining bundles of 100 to 1000 strands with each other, and has higher ductility than single wire nichrome wire, which is a general resistance wire. Because of this, there is a characteristic that shortening of refraction part and disconnection accident do not occur easily. Insulator use of the heating element can be used as a silicon, Teflon coating and the like with high heat resistance and high withstand voltage.

The heating wire 26 is thin and soft, so as to be concentrically wired as shown in FIG. 2, and wires can be wired in various forms.

The metal thin plate 28 covers the heating line 26 wired to the upper surface of the heat storage material 25 and is for diffusing heat generated from the heating line 26. The metal thin plate 28 may be formed of a silver thin plate, a copper thin plate, and an aluminum thin plate having good thermal conductivity. However, in the present embodiment will be described on the basis of using a relatively low cost aluminum foil.

The metal thin plate 28 diffuses the heat generated by the heating wire 26 to the entire heating member accommodating portion 17, and heats the food placed on the diaphragm 17A as a whole through the diaphragm 17A. In addition, since the metal thin plate 28 is attached to the heat storage material 25 while covering the heating wire 26, the metal thin plate 28 also serves to protect the heating wire 26. In addition, the metal thin plate 28 serves to diffuse the heat generated by the heating wire 26 to heat up the entire storage space 14 to evenly heat the food.

The plate-shaped secondary battery 30 is for supplying a DC power to the heating line 26, is formed thinner than the total thickness of the first and second insulation materials 22 and 24 and the heat storage material 25 is laminated, It is provided in the 2nd heat insulating material 22 and 24 and the heat storage material 25. The secondary battery 30 is composed of an ion lithium or a polymer battery.

The secondary battery 30 includes a charging jack 32 electrically connected to the secondary battery 30, and a charger 34 for charging the secondary battery 30 through the charging jack 32. Include.

That is, the secondary battery 30 is charged through the charger 34, and the charger 34 may be provided with a lamp for notifying of the charging, a lamp for notifying the completion of charging, and the like.

The capacity of the secondary battery 30 is satisfactory as long as it can heat the heating wire 26 for about 15 to 25 minutes, but it is preferable to design in consideration of the average delivery time. And, it is preferable that the heating line 26 is designed to generate a heat amount of 75 to 85 ° C.

The above-described secondary battery 30 is formed such that its thickness is thinner than or equal to the sum of the thicknesses of the first and second heat insulating materials 22 and 24 and the heat storage material 25. Accordingly, the secondary battery 30 may be part of the second heat insulating material 24 and the heat storage material 25 so as to correspond to the installation groove 22B and the installation groove 22B formed in the partial area of the first heat insulating material 22. It is inserted into and installed in the installation holes 24A and 25A formed in the grooves. That is, when all of the heat generating members 20 are combined, the secondary battery 30 is inserted into the installation grooves 22B and the installation holes 24A and 25A so as not to protrude to the surface of the heat generating member 20. . At this time, the installation holes 24A and 25A are covered by the metal thin plate 28, but when the installation groove 22B is opened, the secondary battery is closed by closing the installation groove 22B opened using a separate blocking member. The departure of the 30 can be prevented and protected.

In this way, since the secondary battery 30 is provided in the heat generating member 20 itself, the secondary battery 30 needs to be separately provided, or such a space does not have to be provided in the main body 12.

The control unit 40 is electrically connected to the secondary battery 30 and the heating line 26 to selectively supply power of the secondary battery 30 to the heating line 26, and the heating line 26 is for 15 to 25 minutes. Preferably, the heat storage unit 14 is configured to generate heat so as to maintain the temperature of the storage space 14 at a temperature of 75-85 ° C. The controller 40 preferably includes a circuit, a microcomputer, a memory, an on / off switch, and the like. In addition, the control unit 40 may include a bimetal thermostat so that the heating wire 26 generates heat at a constant temperature, and may include a charging circuit.

Hereinafter, the operation of the present invention will be described.

After the heat generating member accommodating part 17 is opened, the heat generating member 20 is inserted.

In this process, the charging jack 32 is exposed to the outside of the main body 12 as the through hole 19.

Subsequently, when the charger 34 is connected to the charging jack 32, the secondary battery 30 is charged.

When the secondary battery 30 is charged in this manner, the control unit 40 supplies the DC power of the secondary battery 30 to the heating line 26 by the user's operation or the like so that the heating line 26 generates heat.

As such, when the heating wire 26 generates heat, the metal thin plate 28 is heated while dissipating heat while dissipating heat. In this process, the heat increases the storage space 14 through the diaphragm 17A. At this time, the heat generated by the heating wire 26 is transferred to the bottom of the heat generating member accommodating portion 17 by the first heat insulating material 22 and the second heat insulating material 24 having the heat storage material 25 and the pores 22A. Heat loss is prevented.

In the state where the storage space 14 is raised, food such as pizza immediately after cooking is completed, is placed in the storage space 14, and the charging jack 32 and the charger 34 are separated from the customer.

Even if the charger 34 is removed in this manner, the heating wire 26 continues to generate heat.

This is because the secondary battery 30 continuously supplies the DC power to the heating wire 26.

In this process, the heating wire 26 generates heat to maintain the food at an appropriate temperature, for example, 75 to 85 ° C., even while the food is delivered to the customer. This series of operations is performed by the controller 40.

That is, the delivery of food is mainly performed between about 10 to 20. As shown in FIG. 4, since the heating wire 26 receives power from the secondary battery 30 and generates heat, the food is delivered during the time of delivery. For example, even when food is delivered from the store and delivered to the customer, the temperature of the storage space 14 is maintained without being lowered. Therefore, the intrinsic taste of the food can be maintained.

In particular, even in the winter when the outside temperature drops below zero, the heat of the food does not fall because it generates heat during delivery as described above.

After the delivery of the food is completed in the above-described process, the discharged secondary battery 30 is returned to the store, and the charger 34 is connected to the charging jack 32 to charge and reuse.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
