Abstract

PURPOSE:To obtain better temperature keeping effect with a simple structure and permit the utilization of exhaust gas of a motorcar and the like for delivering a thing at a person's house for keeping temperature by a method wherein temperature keeping medium is permitted to be poured into, reserved in and discharged out of the box body of a heat insulating box for delivery at a person's house, further, exhaust gas from the motorcar for delivery is passed through the inside of the box body to keep the temperature in the box body. CONSTITUTION:Medium is cooled by a medium cooling tower on the like, installed separately, and, thereafter, is poured by pressure into a pipe 7 through a pouring port 8, then, a discharg ing valve 10 is closed when the small amount of the medium flows out of a discharging port 9 to fill the pipe 7 up with the medium. The refrigerant, whose temperature is risen after finishing delivery, is discharged out of the pipe 7 by opening the discharging valve 10 while the medium, newly cooled, is poured into the pipe 7 to replace the old medium with the new medium when a next delivery is effected. The exhaust gas pipe of a motorcar 16 is connected to the inlet port 18 of a pipe 17. The exhaust gas passes through the pipe 17 to provide a food compartment 11 in a heat insulating box 12 with sufficient temperature keeping effect, since the temperature of the exhaust gas is pretty high, while the exhaust gas is discharged out of a discharging port 19.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention is suitable for delivering hot food and drinks to customers while keeping them hot and keeping cold food and drinks cold. Regarding insulated boxes for home delivery.

(b) Conventional technology Conventionally, as a vehicle for transporting these cold or hot drinks,
The most commonly seen items are the rice bowls for delivery at soba restaurants, and the ones with a cover attached to the back of the delivery bites at soba restaurants that simply hold food and drinks in place. Alternatively, there are some slightly improved insulated boxes that can be carried around, such as cooler boxes.

(c) Problems to be solved by the invention However, as mentioned above, rice cookers or simple insulated boxes do not have sufficient cold or heat retention effects, so by the time the hot food reaches your home, the hot food will have cooled down. There has been a problem in that the product value is significantly reduced because the product is stored away and cold food and drinking water become lukewarm. In addition, especially in recent years, a new food service industry called home delivery pizza has appeared, and it is undeniable that heat retention measures are extremely important in these industries.

The present invention has been made in view of the above points, and is a novel insulated box for home delivery that has a simple structure, provides even better heat and cold insulation effects, and utilizes exhaust gas from vehicles used for home delivery for heat insulation. The purpose is to provide the following.

(d) Means for Solving the Problems The insulated box for home delivery according to the present invention is capable of injecting and storing a medium for keeping cold or warm inside the insulating box for delivery, and discharging it after use. The structure is such that exhaust gas from automobiles and motorcycles is passed through the body of the insulating box to maintain heat.

(e) Function When delivering to home, an appropriate medium for cold storage or thermal insulation is injected from the outside into the inside of the insulated box and stored there. By doing this, the inner wall portion of the sheath that receives the food and drink is kept in a cooled state or a high temperature state by the medium, so the food and drink remains cold or hot.
delivered to the orderer.

After delivery, the medium that has lost its cold-retaining ability and heat-retaining ability is discharged from the insulated box, and a new medium can be poured into the box. On the other hand, exhaust gas from motorcycles and automobiles traveling during delivery passes through the inside of the insulated box, and this exhaust gas maintains the walls of the box at a high temperature.

Food and drinks inside the box are kept hot.

(f) Example Embodiments of the present invention will be described below based on the drawings.

On the top, a heat insulating material 4 such as urethane foam is placed between the inner box 2 and outer box 3.
Inside the box body 2, which is an insulated box for home delivery consisting of a box body 5 filled with a heat insulating material 5 and a lid body 6 similarly filled with a heat insulating material 4, are cold storage media with names as described below, A pipe 7 into which a heat-retaining medium is placed is tightly wound and attached to the outer surface of the inner box 2. Inlet 8 of the pipe 7 into which the medium is introduced
protrudes from one side of the box body 5, and a discharge port 9 through which the medium is discharged protrudes from the bottom of the box body 2 via a medium discharge valve 10.

Here, to explain the case where this insulation box 1 is used for cold storage, representative examples of the medium for cold storage include liquids with high specific heat such as ethylene glycol and propylene glycol, or liquid carbon dioxide. It will be done. Therefore, after being cooled by a separate medium cooling tower (not shown), etc., the medium is injected by connecting a valve at the end of the hose to the inlet 8 of the pipe 7. It is fed under pressure into the pipe 7 from the inlet 8, and the discharge port 9
When a small amount of the medium has flowed out, the discharge valve 10 is closed and the medium is poured into the pipe up to 7 cups.

By storing the cooling medium in the vibrator 7 in this way, the inner box 2 portion of the box body 5 is cooled, while the conduction of heat from the outside air is prevented by the heat insulating material 4. The cold air in the food and drink storage section 11 in one box will be kept at a low temperature for a long time, and the food and drink inside will be cooled by the cold air.

Therefore, cold dishes (such as cold noodles), beverages such as juice and beer, and various foods and drinks such as sashimi that become better when cooled are placed in the storage section 11 and covered with the lid body 6, as shown in FIG. It is placed on the platform of a home delivery vehicle 20 as shown in FIG. 2 and delivered to a home or the like. The delivered food remains cold and delicious without sacrificing flavor.

In this way, the refrigerant whose temperature has risen after the delivery is discharged to the outside of the vibrator 7 by opening the discharge valve 10, and is replaced with a newly cooled medium and injected at the time of the next delivery. In this way, the cooling medium can be replaced quickly and easily by the valve connection which can be connected to the inlet 8 of the pipe 7 with one touch.

In this embodiment, the pipe 7 is tightly wound around the inner box 2, but a space layer may be provided within the box body 5, and a medium may be filled in the space layer for cooling.

When this insulated box 1 is used as a heat-insulating box for storing hot food and drinks and maintaining it at that temperature,
A hot medium such as hot water may be similarly injected.

Next, the insulation for delivery according to the second invention of the present invention is improved so that the insulated box is heated using the exhaust gas of the delivery vehicle, etc., so that soba, udon, pizza, etc. can be delivered hot and still. Explained on the box.

First, the insulation box 12 for home delivery shown in FIG. 3 has almost the same structure as the insulation box 1 described above, and the insulation material 4 is filled between the inner box 13 and the outer box 14 to form a box body 15. Similarly, insulation material 4
A lid body 16 is provided.

Inside the wall of the box body 15 is a pipe 17 that extends over the entire outer circumferential surface of the inner box 13 and is in close contact with the inner box 13 to allow exhaust gas to flow therethrough.
is wound. One end of the pipe 17 serves as an inlet 18 for exhaust gas, and the other end serves as an outlet 19 for exhaust gas, each of which protrudes outside the box 15.

By the way, what is shown in FIG. 5 is this home delivery insulation box 12.
The exhaust gas pipe 21 of the vehicle 16 is connected to the pipe 1 of the insulation box 12 in a delivery vehicle 20 that carries out delivery by placing the vehicle on its platform.
It is connected to the inlet 18 of 7. Therefore, the exhaust gas passes through the pipe 17 and the exhaust heat is quite high temperature, so the food/drink storage section 11 inside the heat insulating box 12 has a sufficient heat retention effect, and hot food/drinks are not trapped. The exhaust gas is then discharged from the exhaust port 19. In this way, heat retention inside the insulation box 12 becomes more sufficient by using exhaust heat, making it possible to deliver hot food to homes in a still hot state, and reducing product value as much as possible without incurring costs. This can be prevented. In the case of home delivery by Baits or the like instead of the automobile 20, the exhaust gas may be passed through the pipe 17 in the same manner. Alternatively, instead of using the pipe 17, as shown in FIG.
Exhaust heat may be used to obtain a heat retention effect.

(g) Effects of the Invention As described above, according to the present invention, a medium for cold or heat preservation is injected and stored from the outside into the box body of an insulated delivery box, and the medium is used to keep the inside of the box for a long period of time. Since it can be kept cold or hot for a long time, the food and drink inside can be delivered without getting lukewarm or getting cold. Therefore, it can be enjoyed cold or hot, and a decrease in product value can be prevented. When the medium loses its cold or heat retaining effect, it can be ejected from the box and replaced with a new medium.
Moreover, since the medium can be injected by a one-touch valve connection, the operation is simple.

In addition, by adopting a structure in which the exhaust gas from delivery cars, bites, etc. is discharged through the inside of the insulated delivery box, the high-temperature exhaust heat is used to maintain the heat inside the insulated box. It has excellent effects, such as being able to deliver hot food and drinks at the same temperature without much expense.
