Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cold storage device in which a plurality of cold storage plates are supported inside a cold storage plate type refrigerator, which is a type of vehicle-mounted cooling container.

[Prior Art] In a conventional cold storage device, a cold storage plate mounting device is made up of a number of columns vertically installed at regular intervals inside a cold storage plate type refrigerator, and the cold storage plate is sandwiched between these columns to store cold. It is designed to sandwich the side walls of the plate. The cold storage plate is fixed to the pillar of the cold storage plate attachment with bolts.

On the other hand, a cold storage plate is made up of a flat cold storage container with good thermal conductivity and a cold storage agent filled in this cold storage container. The evaporation pipe is housed within this cold storage plate.

On the other hand, in a cold storage plate type refrigerator, the inside of the refrigerator is cooled through an evaporation pipe by a refrigeration system using commercial power at the base. At this time,
The cold storage plate is also cooled and stored by the evaporation pipe. When the cold storage plate type refrigerator is transported by a truck or the like, the inside of the refrigerator is cooled by the cold storage plate. At this time, in order to efficiently cool the inside of the refrigerator, a fan provided inside the refrigerator creates a wind circuit that circulates inside the refrigerator. A part of this wind circuit runs along the side wall of the cold storage plate.

[Problems to be solved by the invention] As mentioned above, in the conventional cold storage plate mounting tool, the cold storage plate had to be fixed to the pillar with bolts, and the installation work was very troublesome.

Furthermore, in the conventional cold storage plate mount, the pillars close the space between the cold storage plates and act as a resistance for the wind circuit that circulates inside the refrigerator. For this reason, there was a problem in that the inside of the refrigerator was not efficiently cooled by the cold storage plate.

Therefore, an object of the present invention is to provide a cold storage device having a cold storage plate mounting tool that allows the cold storage plate to be easily attached and allows the cold storage plate to efficiently cool the inside of the refrigerator.

[Means for Solving the Problems] According to the present invention, in a cold storage device including a plurality of cold storage plates disposed in a cold storage plate type refrigerator and a cold storage plate attachment that supports the cold storage plates, the above-mentioned mounting The tool includes a frame body in which the plurality of cold storage plates can be arranged, and a plurality of fixing parts that are attached to the frame body at intervals in the predetermined direction, and have a pair of clamping parts facing each other in a predetermined direction. and each of the plurality of cold storage plates is inserted between the pair of sandwiching parts so as to be removable in a direction intersecting the predetermined direction.

[Function] In the present invention, the installation of the cold storage plate is completed by simply holding the cold storage plate between the fixtures.

Furthermore, since the cold storage plate mount according to the present invention is provided with the fixing devices at regular intervals, when the cold storage plates are attached to each of the fixing devices, there is a gap between the cold storage plates. Therefore, since the air circulating inside the refrigerator can pass through this, the air inside the refrigerator is efficiently cooled by the side wall of the cold storage plate.

Referring to FIG. 1, the cold storage device includes a frame 1, a fixture 6, and a cold storage plate 20. The frame body 1 is made up of a combination of vertical bars 2, horizontal bars 3, and vertical bars 4. These rods 2, 3, and 4 are made of metal and have a substantially L-shaped cross section. The frame 1 is fixed in a regenerator type refrigerator (not shown) with bolts or the like.

The fixture 6 consists of four vertical rod parts 7, two horizontal rod parts 8 whose both ends follow the vertical rod parts 7, and two horizontal rod parts 9 that connect the vertical rod parts 7 on the same side. Become. The vertical rod portion 7 and the horizontal rod portion 8 constitute one clamping portion. The clamping parts face each other, and between them,
The side edges of the cold storage plate 20, which will be described later, are held. The fixture 6 is formed by bending a wire having a circular cross section so that it has a substantially U-shape when viewed from the front and side. The fixtures 6 are attached to the upper and lower parts of the frame 1 at regular intervals. Frame 1
The fixture 6 at the top of the frame 1 and the fixture 6 at the bottom of the frame 1 face each other, and hold one cool storage plate 20 between them.

The cold storage plate 20 shown in FIG. 1 includes a first sealed container 21 and a second sealed container 2 filled with a cold storage agent.
2, and the evaporation pipe 23 is sandwiched between the first hermetic container 21 and the second hermetic container 22 for use. Note that this type of cold storage plate was filed by the present applicant prior to the present invention (for example, Utility Model Application No. 62-35341).

Side walls 24 of the first and second closed containers 21 and 22
The fittings each have a vertical groove 25 with a semicircular cross section corresponding to the vertical rod part 7 of the fixture 6, and a horizontal groove 26 with a semicircular cross section at a height corresponding to the horizontal rod part 8 of the fixture 6. A matching groove 27 is provided. This fitting groove 2
The cold storage plate 20 is configured not to come into contact with the frame 1 when the fixture 6 is fitted to the frame 7.

FIG. 2 is an enlarged sectional view showing a fitted state of the fixture and the cold storage plate in the embodiment shown in FIG. 1.

With reference to FIG. 2, the horizontal rod portion 8 of the fixture 6;
Side walls 24 of the first and second two sealed containers 21 and 22
The lateral groove 26 provided in the lateral groove 26 is configured to fit tightly. Therefore, the horizontal rod portion 8 and the lateral groove 26 are in surface contact with each other.

Returning to FIG. 1, in order to attach the cold storage plate 20 to the cold storage plate mounting tool, it is only necessary to push the cold storage plate 20 in the direction of the arrow and have the side edges of the cold storage plate 20 sandwiched by the fixtures 6. At this time, the cold storage plate 20 is smoothly guided into the frame 1 by the horizontal rod portion 8 of the fixture 6 and the horizontal grooves 26 of the cold storage plate 20.

FIG. 3 is a perspective view showing the state in which the embodiment shown in FIG. 1 is used.

Referring to FIG. 3, the cold storage plate attachment 10 is installed in a cold storage plate type refrigerator (not shown). Four cool storage plates 20 are mounted on this cold storage plate attachment 10 at equal intervals. Therefore, a gap is created between the cold storage plates 20. Air within the refrigerator can pass through this gap as shown by the arrow due to the suction force of a fan 28 (simplified illustration).
Therefore, the resistance of the wind circuit that circulates inside the refrigerator is low. Furthermore, since the air inside the refrigerator passes between the cold storage plates 20 and 20, the air inside the refrigerator passes between the cold storage plates 20 and 20.
It is efficiently cooled by the side wall 24 of. The air cooled in this manner is sent to every corner of the refrigerator by the fan 28 to cool the stored items. The air that has cooled the stored items is made to pass between the cold storage plates 20 again by the suction force of the fan 28.
