Description

[Detailed description of the invention] [Field of industrial application] The present invention is a cooling device equipped with a removable cold storage box, in particular, a cooling machine section and a cooling section are separated, and the contents of the removable cold storage box are separated in the cooling section. This invention relates to a cooling device equipped with a removable cold storage box that can cool a container.

[Conventional technology]

Portable electric refrigerators and ice box-type cold storage boxes are known as simple portable refrigerators.

[The problem that the idea aims to solve]

Conventional portable electric refrigerators have good cooling performance and low running costs, but they are expensive, make noise, and are heavy, making them difficult to carry. On the other hand, conventional ice box type cold storage boxes have the advantages of being cheap, producing no noise, and being light in weight. However, since they use ice, dry ice, cold storage material, etc. However, their cooling performance was not as good as that of electric refrigerators.

The present invention takes advantage of the advantages of both of the above, and includes a removable cold box and a cooling device that cools the inner container of the cold box. To provide a cooling device equipped with a removable cold storage box that can be used alone as a cold storage box even after cooling and removing the cold storage box from a cooling section of the cooling device.

[Means to solve the problem]

In order to achieve the above object, the cooling device equipped with a removable cold storage box of the present invention has an opening in the upper part, a cooling part in which a removable part is provided, an outer box, and an inner container. It has a heavy-walled structure, and the inner container is made of a cool storage material, and a detachable part is provided at the lower part of the inner container, and the lower part of the inner container is attached to the opening of the cooling part through the detachable part. It is characterized by being equipped with a portable cold storage box and a cooling machine section that supplies refrigerant to the cooling section.

[Effect]

To cool the inside of a cold storage box, the lower part of the cold storage box is attached to the opening of the cooling section, and the refrigerant sent from the cooling machine section to the cooling section cools the inner container of the cold storage box made of cold storage material. After cooling the inner container, remove the cold box from the cooling section,
The bottom of the outer box is attached and used as a stand-alone cold storage box. This will be explained below with reference to the drawings.

〔Example〕

FIG. 1 is a configuration diagram of an embodiment of a cooling device equipped with a removable cold storage box according to the present invention, FIG. 2 is an external perspective view of the cooling device, and FIG. 3 is a diagram showing how the removable cold storage box is installed during cooling. FIGS. 4A and 4B are diagrams illustrating the structure of the cold storage box during transportation and use.

In FIGS. 1 to 3, a cooling machine section 2 and a cooling section 3 are arranged adjacent to each other on a substrate 1 with a pipe 4 interposed therebetween. The cooling machine part 2 is the cooling part 3
This is a device for sending cooling refrigerant to the refrigerator, and since the device used in general freezers is used, its explanation will be omitted. A cord 5 is attached to the cooling machine section 2, and power is supplied from a commercial power source or a battery.

An evaporator 8 is disposed on the inner wall of the cooling section 3 and its bottom surface to directly cool the inner container 7 of the cold box 6 to which it is attached. The upper part of the cooling section 3 is open, and a detachable mechanism, for example, a threaded section 9, is provided at the open end. The inside of the cooling section 3 is filled with a heat insulating material 10, and the cooling section 3 is effectively cooled by the evaporator 8. The substrate 1 includes a cooling temperature setting section 11 for setting a cooling temperature.
is provided.

On the other hand, the cold box 6 attached to the cooling section 3 is constructed as follows. In other words, the outer box body 1
The inside of the outer box body 12 is filled with a heat insulating material 13 for blocking heat conduction, and a threaded portion 14 is provided at the lower end of the outer box body 12. The threaded portion 14 is screwed into the threaded portion 9 provided on the cooling section 3, so that the cold box 6 is attached to the cooling section 3. An inner container 7 made of a cold storage material is integrally provided on the inner wall of the outer box body 12 by, for example, adhesive or fitting. It has a double wall structure with an outer box body 12. Further, the upper end of the outer box body 12 is structured to be covered with a lid 16 that is engaged so as to be openable and closable, and the inside of the lid 16 is also provided with a heat insulating material to block heat conduction. 17 is filled. An annular packing 18 is placed on the upper end of the outer box body 12 to maintain close contact with the lid 16.

A metal fitting 19 for attaching a handle is provided on the side surface of the outer box body 12, and a handle 20 for carrying is attached to the metal fitting 19 (see FIG. 4).

The cold box 6 constructed in this manner is attached to the cooling section 3 via the screw portions 9 and 14 of the attachment/detachment mechanism as shown in FIG. Under such a state as shown in FIG.
When the refrigerant is sent to the evaporators 8 disposed on the inner wall and the bottom surface of the inner container 7, these evaporators 8 directly cool the lower part of the inner container 7 made of a cool storage material. The inner container 7 is connected to the cooling section 3 as described above.
Since the inner container 7 is covered with the heat insulating materials 10 and 13 filled in the outer case body 12, the entire inner container 7 is efficiently cooled. After sufficiently cooling, remove the cold box 6 from the cooling section 3 and place it in the outer box bottom body 21 shown in FIGS. 4A and B, which will be used during transportation.
The lower part of the inner container 7 of the cold storage box 6 is attached.
The upper end of the outer box bottom body 21 has a screw portion 22 for attachment and detachment.
The threaded portion 22 and the threaded portion 14 provided on the outer case body 12 are screwed together, and the outer case body 12 and the outer case bottom body 21 are integrated. The outer box bottom body 21
The inside is also filled with a heat insulating material 23 to block heat conduction. In addition, a gasket 24 is provided at the joint between the outer box body 12 and the outer box bottom body 21.
is laid out.

By assembling the outer box bottom body 21 as shown in FIG. 4B, the inner container 7 is covered with a heat insulating material.
It has a heavy-walled structure and functions as a portable cold storage box. At this time, the inner container 7 made of cold storage material
The cooling box itself becomes a cooling source, making it possible to effectively use the inside of the cold storage box, and the displayed internal volume matches the practical internal volume.

Further, it goes without saying that the structure is such that it can be used as a refrigerator with the cold storage box 6 installed in the cooling section 3 without having to take it out.

Note that the cooling section 3 does not necessarily need to be provided adjacent to the cooling machine section 2, and may be arranged above the cooling machine section 2, for example. Furthermore, the mechanism for attaching and detaching the cold storage box 6 and the cooling section 3 or the outer box bottom body 21 is not limited to a screw mechanism.

[Effect of idea]

As explained above, according to the present invention, it is possible to realize a cooling device that can be used as a cold storage box that has both the advantages of a portable electric refrigerator and the advantages of an ice box type cold storage box.

The cold storage box exhibits excellent functions in terms of cooling performance, product price, running cost, noise, weight, etc.
