Description

[Detailed description of the invention] This invention is for storing objects to be cooled, such as fruit, barley tea, juice, canned beer, or fish during fishing, or heated objects such as bento lunches, tea, coffee, and soup, in an insulated container. It is stored with objects and used to cool or heat the stored objects, and it is used as a cooling source by putting liquid in the container body and freezing the liquid in the ice-making compartment or freezer compartment of the refrigerator, Alternatively, the present invention relates to a heat source container in which a high temperature liquid is placed inside the container body and used as a heating source.

Generally, in this type of heat source container, heat transfer from the heat source housed in the container body is carried out through the surrounding wall of the container body, in other words, the heat exchange area is determined by the size of the container body. As described above, when the container body is housed in the heat insulating container together with the object to be cooled or heated and the container body is cooled or heated, there is a problem in that the cooling or heating takes time.

In addition, the container body is usually made of synthetic resin and is formed by blow molding, and in this case, it can be manufactured at a very low cost7, but on the other hand, it has poor heat conduction and is difficult to cool the object to be cooled or the object to be cooled. There was a problem in that it took more time to heat the object.

Therefore, the present invention was devised to solve the above-mentioned problems, and its purpose is to cool objects to be cooled or heat objects to be heated extremely quickly and unevenly. To provide a heat source container that can be used without any problems, has a simple structure, and can be implemented at low cost.

That is, the present invention is a heat source container that stores a liquid in the container body, freezes or heats the sample liquid body as a heat source, and cools or warms the surrounding air by heat transfer from this heat source. A heat exchange plate is formed from a material, and the heat exchange plate is formed separately from the container body, and an opening is provided in the container body, and the heat exchange plate is connected to the container body through the opening. The device is characterized in that it is attached so that a portion thereof is exposed inside the container body, and heat transfer from the heat source is performed via a heat exchange plate.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a container body made of synthetic resin and formed into a hollow shape by blow molding.A liquid injection port 11 is formed in this container body 1, and liquid is poured into the container body 1 from the liquid injection port 11. At the same time, a threaded groove is formed on the inner periphery of this liquid injection port 11.

Reference numeral 2 denotes a disk-shaped heat exchange plate made of a material with good thermal conductivity, for example, metal such as aluminum, and the approximate center of the heat exchange plate 2 is bulged toward one side to form a bottomed cylinder. A shaped mounting portion 21 is formed, and a screw groove is formed on the outer periphery of the mounting portion 21.

Thus, the mounting portion 21 of the heat exchange plate 2 is attached to the container body 1.
The top surface of the mounting part 21 is exposed inside the container body 1, and the mounting part 21 is used to close the liquid injection port, and the heat exchange plate 2 is attached to the container body 1. The heat source attached to the main body 1 and housed in the container main body 1 is exposed to the outside of the container main body 1 from the top surface of the mounting part 21 exposed inside the container main body 1 through the mounting part 21. The heat exchanger plate 2 is moved to the plate-shaped portion.

In addition, 3 in the figure is a heat-insulating container in which the heat source container of the present invention is used, and is composed of a main body 31 and a lid body 32 having a heat-insulating structure.
A step portion 33,32 for receiving the container body 1 is formed on the inner periphery of the upper end opening of the main body 31.

The heat source container of the present invention is constructed as described above. For example, after removing the heat exchange plate 2 from the liquid injection port 11 and pouring liquid into the container body 1 from the liquid injection port 11, After attaching the heat exchange plate 2 again or removing the heat exchange plate 2, insert the container body 1 into the ice making compartment or freezing compartment of the refrigerator,
The liquid in the container body 1 is frozen and turned into ice.

In this way, when storing and cooling objects to be cooled, such as fruit, juice, coffee, canned beer, or fishing fish in the insulated container 1, the container body 1 is removed from the ice-making compartment or freezing compartment of the refrigerator. When the heat exchange plate 2 is taken out and the heat exchange plate 2 is removed, the heat exchange plate 2 is attached to the liquid injection port 12 of the container body 1, and the container body 1 is placed inside the heat insulating container 3, and the heat exchange plate 2 is removed. The inside of the heat insulating container 3 is placed so that it faces downward, so that the object to be cooled in the heat insulating container 3 is placed in the container body 1.
Heat is exchanged with the ice inside through the heat exchange plate 2, and the object to be cooled is rapidly cooled.

However, if the object to be cooled by the lever does not need to be cooled rapidly, the container body 1 may be placed inside the heat-insulating container 3 with the heat exchange plate 2 facing upward, or a small-diameter heat exchanger prepared separately may be used. The heat exchange plate 2 can be replaced with an exchange plate, or a cap (not shown) can be attached to the liquid injection port 11 in place of the heat exchange plate 2, whereby the amount of heat exchange is suppressed and the object to be cooled gradually cools. It will be cooled down.

As in the previous embodiment, the cap of the liquid injection port 11 is attached to the heat exchange plate 2.
When the mounting part 21 is used for the same purpose, the opening and closing of the liquid injection port 11 can be done extremely smoothly and reliably.In other words, the heat exchange plate 2 has a very large diameter compared to a normal cap.
This rotation of the heat exchange plate 2 can be easily performed with a small force.

Furthermore, as shown in FIG. 3, an opening 12 is formed in the container body 1 in addition to the liquid injection port 11, and a heat exchange plate 2 is inserted into the opening 12.
You may also use force to install it.

In this case, a cap 13 is detachably attached to the liquid injection port 11.

In addition, the molding of the container body 1, especially the mounting portion 21 of the heat exchange plate 2,
may be buried integrally by an insert method.

Further, the mounting portion 21 of the heat exchange plate 2 is fitted into the opening 12 of the container body 1, and the mounting portion 21 is caulked to form the opening 12.
It may be installed integrally with the

In this case, as shown in FIG. 3, the opening 12 is provided opposite the liquid injection port 11, and the mounting portion 21 is caulked through the liquid injection port 11.

As explained above, in the present invention, a heat exchange plate made of a material with good thermal conductivity is formed separately from a container body containing a liquid serving as a heat source, an opening is provided in the container body, and the heat exchange plate is made of a material with good thermal conductivity. was attached to the container body through the opening so that a portion of the container body was exposed inside the container body, so that the container body was lightweight and could be formed simply and easily, but on the other hand, it was made of a synthetic resin with poor thermal conductivity. In this case, the heat of the heat source housed in the container body is exposed to the plate-like portion of the heat exchange plate from the attachment portion of the heat exchange plate to the container body exposed to the outside of the container body. This allows heat to be radiated from this plate-shaped portion, increasing the amount of heat exchanged per unit time.

Therefore, when the heat source container is housed in the heat insulating container together with the object to be cooled or heated, the object to be cooled or heated can be rapidly cooled or heated in a short time.

Moreover, since the heat transfer from the heat source housed in the container body is carried out through a heat exchange plate formed separately from the container body, the container body is small and made of synthetic resin with poor heat conduction. However, by forming the heat exchange plate larger than the container body, the amount of heat exchange per unit time can be increased.Furthermore, when housed in an insulated container, the position of the heat exchange plate For example, the amount of heat exchange can be controlled by changing the position of the heat exchanger to the upper side or the lower side with respect to the container body, or by changing the size of the heat exchange plate.

In addition, a heat exchange plate is formed separately from the container body, and
It has an extremely simple structure of just providing an opening in the container body and attaching the heat exchange plate to the opening, and the container body can be made of synthetic resin.
It is lightweight, allows for a large amount of heat exchange per unit time, and can be formed at low cost since the amount of heat exchange can be controlled.
