Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable cooler, and more particularly to a foldable cooler.

Conventionally, there were things called portable refrigerators or simple refrigerators, but the former was a smaller ordinary household refrigerator, and the power supply was dual-purpose (AC 100V and DC 12V).
), and the latter did not use a cooling cycle, but instead used a heat storage material (ice or other chemical substance) stored inside the refrigerator.

However, in the former case, it cannot be used where there is no power supply.

In other words, it is impossible to cool the car, and even if it is loaded into a car, it will not cool down if the engine is stopped, and the battery cannot be used for a long time. Therefore, there has been a desire for a portable cooler that is small, lightweight, easy to carry, and has excellent cooling capacity.

The present invention was developed in view of the above points, and its purpose is to make the cooling unit having a compressor, condenser, and evaporator and the storage with heat storage material attached to it detachable, so that the storage can be removed. To provide a portable cooler in which the cooling unit can be made more compact and its transportability and operability can be further improved.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 is a cooling unit, and 2 is a storage, both of which are detachable using clasps or the like.

The former cooling unit 1 includes a compressor 4, a condenser 5, and an evaporator 6.
, a switch panel (not shown) is installed, and this compressor 4
is used for both alternating and direct use.

A hand-rest part for carrying may be provided on the side surface of the cooling unit 1.

On the other hand, the storage 2 is made of a highly insulating material and has a box-like shape with an open top, a heat storage material 9 is attached to the inner surface, and the top opening can be covered with a top lid 10.

The top surface is open for taking things in and out of the storage 2, but the top surface may be closed and a door may be provided on the side.

Furthermore, when the clasp is removed and the storage 2 is removed from the cooling unit 1, the storage 2 can be carried around by attaching a belt 11.

The cooling unit 1 is formed in a U-shape, and is configured such that the storage 2 is inserted from the side with a guide plate 12 as a guide, and the evaporator mounting base 13 serves as the top cover of the storage 2.

When the storage compartment 2 is pulled out, the cooling unit 1 becomes as shown in FIG. As shown in the figure, it is smaller and easier to carry.

15 is a capillary tube.

In this case, the refrigeration cycle piping near the hinge 14 is made of bendable, flexible material.

On the other hand, the storage 2 pulled out from the cooling unit 1 can be easily carried by covering it with a top lid 10 and attaching a belt 11, as shown in FIG.

The operation of the present invention configured as above will be explained with reference to the drawings.

Attach cooling unit 1 and storage 2 with clasps, and compressor 4
If energized, it can be used as a refrigerator.

As mentioned above, the storage 2 is made of a highly insulating material,
Since a heat storage material 9 is attached inside, when the cooling unit 1 is operated, the food and other items stored in the storage 2 are cooled, and the heat storage material 9 absorbs cold air, and the cooling unit 1 stops operating. do.

Furthermore, even when removed, its cold retention is higher than that of a regular refrigerator, making it useful as a cold storage.

For example, consider loading a car and going out.

By first cooling the vehicle using household power and then continuing to cool it using the engine power while in the car, it is possible to maintain a cool state for a long time even if the car engine is turned off after reaching the destination.

If the storage compartment 2 is removed and the belt 11 is attached, it can be carried around, and cold food and drinks can be easily obtained in a place where a car cannot enter.

Although not shown, if a fan for blowing air is provided separately, the storage compartment 2 can be removed and the fan can be operated to use it as a car cooler, or at home, it can also be used as a so-called portable cooler.

Moreover, the storage 2 can be used as a cooler if it is cooled by a different method.

Furthermore, if the cooling unit 1 is folded, it can be made more compact, and for example, when returning from a trip by car, it can be folded and placed in the trunk to make more use of the seat.

As described above, according to the present invention, the cooling unit having the AC/DC compressor, condenser, and evaporator, and the storage with the heat storage material attached can be freely attached and detached. It is capable of cooling operation, and as a result, the storage compartment has a higher degree of cold retention compared to conventional so-called simple refrigerators that use ice and other chemicals, and the storage compartment can also be used as a cold storage, eliminating the stereotype of a conventional refrigerator. This novel idea has extremely beneficial effects, such as being able to be made more compact and more transportable and manoeuvrable, even though it uses a refrigeration cycle.
