Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a portable cold storage box that is mounted on a general vehicle and used for driving, outdoor sports, fishing, camping, etc., or for transporting blood in an emergency, and the inside of the box. This invention relates to a cooling box device for a vehicle consisting of a cold storage and heat storage device.

[Conventional technology]

Recently, the so-called outdoor lifestyle has become popular, and opportunities for camping and enjoying outdoor barbecues are increasing. At that time, cooler boxes made of hard plastic or styrofoam have become indispensable to keep drinks, meat, fruits, etc. cold. These cooler boxes contain ice and cold storage agents along with drinks and food.

Also, for in-vehicle use, the cooling unit of the cooler can be shared□
In addition to internal cooling, there are also cold and hot refrigerators that use electrical heating to keep the interior warm.

[Problem to be solved by the invention]

However, in the case of the above-mentioned cooler box, it is almost impossible to control the internal temperature, and since there is a decrease in the amount of ice and a decrease in the cooling ability of the cold storage agent, it is impossible to keep it cold for a long time. On the other hand, in the case of a vehicle-mounted cold storage, it is possible to control the temperature to some extent, but it is not possible to separate the temperature inside the refrigerator.

In addition, because it is a stationary type inside the car, it cannot be taken out of the car, and because it is installed inside the car so as not to get in the way, it has no choice but to be limited in capacity.
The disadvantage is that the items and amount of storage are limited.

The present invention has been made with the aim of eliminating such drawbacks, and the following points can be further cited as background of the present invention. That is, the recent three-temperature transport (
+5°C1±0°C1-18°C) has become -boat fishing, and the number of users is increasing significantly. However, in the future, as the gourmet boom continues to heat up, the idea of wanting to transport and eat fresh food with one's own hands, without using delivery systems or other transportation systems, will naturally emerge. Conceivable. For example, it is predicted that it will become a daily routine for people to go to a fishing port first thing in the morning, buy freshly caught fish, and put it on their own family's table in the evening. Until now, it would have been very difficult for individuals to deliver products directly from the farm.

In addition, when transporting blood in emergencies, it was difficult to transport the required amount at a stable temperature, but in anticipation of the fact that there would definitely be a need for a means to convert blood into containers, this book was developed. The inventor has made this invention.

[Means to solve the problem]

) has solved the above problem.

[For production]

The inside of the cold box 1 is cooled or heated by inserting the protruding guide plate 7 into the insertion opening 8, starting the engine of the car, and starting cooling or heating by the guide plate 7. When moving the cold box l at the destination, the guide plate 7 can be pulled out from the insertion opening 8.

〔Example〕

Preferred embodiments of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a cold box, which is usually made of hard plastic containing a heat insulating material. A handle 2, a belt 3, etc. are attached to the cold box 1, and/or a finger hook 4 is provided to make it convenient to carry. Naturally, the cold box 1 has a top surface (Figures 2 and 3) or a side surface (the fourth
5) is provided with a lid 5. When the lid 5 is provided on the side, it should be placed so that the stored items do not roll out when opened.
It is preferable to install a telescopic guard 6 such as a bellows 6 (
Figure 4). An insertion opening 8 into which a flat guide plate 7 is tightly inserted is formed on the bottom surface (FIGS. 2 and 3) or side surface (FIGS. 4 and 5) of the cold box 1. Insertion port 8
There is a constant insertion hole 8 inside due to the action of a torsion coil spring, etc.
An inner lid 9 is installed which is pressed against the inner edge of the. The inner lid 9 is pushed open when a force equal to or higher than the spring pressure of the spring is applied from the outside, and the closed state is maintained again when the pressing force is removed. In addition, by providing a sponge or dense bristles on the inner peripheral edge of the insertion port 8, the guide 1'
The airtightness when inserting the plate 7 can be further improved. As shown in FIGS. 2 and 3, when the guide plate door is inserted from the bottom, a partition wall 10 is provided to prevent moisture from adhering to the guide plate 7 and reducing the cooling capacity. It is preferable. It is preferable that the tip of the guide plate 7 be tapered in order to make the guide plate 7 move more smoothly into the insertion port 8.

In addition, when the cold box I is not installed, the guide plate 7
Since the protruding guide foot door is a nuisance, the guide foot door is usually made foldable. Preferably, a concave portion 11 is formed in the floor so that the guide plate 7 is accommodated therein when folded, and M12 is placed over the concave portion 11 so that 112 is flush with the floor. 13 is located at the top of the outside of the cold storage box 1 (
