Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice storage tank of a long-term storage device for preserving fruits, vegetables, flowers, fish and the like. Strictly speaking, the ice storage tank is sometimes called an ice storage tank because it keeps water and ice coexisting.
Further, the storage device may be referred to as a storage system or a storage.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Patent Application Laid-Open Publication No. 4-55647, a group of ice storage tanks is stacked by using wooden spacers arranged vertically and horizontally so that air can flow around. Has been raised. For this purpose, a method has mainly been adopted in which plastic containers are stacked in a stack via spacers.

The present invention has been made in view of the above-mentioned problems of the prior art, and further enhances the function of an ice storage chamber disclosed in Japanese Patent Application Publication No. 4-55647.

[0004]

In the prior art, the amount of water stored is limited to 80% of the ice storage tank mainly because plastic containers are used for stacking. This was to cope with a problem in that when the water in the ice storage tank was frozen, the expansion caused the ice to push up the spacer. Therefore, there was a problem that the ice storage space could not be maximized. In addition, when water is injected into the group of ice storage tanks, when water is supplied or supplied, it is necessary to pour water while stacking containers, which is troublesome.

[0005]

Means for Solving the Problems As means for solving the problems, an overflow port for water is added to the structure of the ice storage tank itself only by the water injection means provided above the group of ice storage tanks. Means for assembling the ice storage tank group by making a slope on the surface were designed.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG.
1 is a perspective view of a representative embodiment of the present invention. further,
2 and 3 are views as viewed from the side from the top. The ice storage tank 1 is made of steel, but is made of aluminum,
A similar structure can be formed with plastic. One sheet of steel is roll-formed to have the tank structure shown in FIG.
A hole 3 for attaching the support rod 10 of the ice storage tank group 12 is provided in the edge 4 of the tank. In addition, the injected water 5
The notch 8 is pushed and bent to form the overflow port 2 so that the water is efficiently injected into the lower water injection tank 1b.

The ice storage tank 1 of FIG. 1 is assembled with a support rod 10 to form an ice storage tank group 12 of FIG. When water flows out of the faucet 14 of the water injection means attached to the uppermost part by the control solenoid valve 14, when the water that has entered the uppermost ice storage tank 1 a is filled, the outer side surface 5 of the ice storage tank 1 is removed from the overflow port 2. The structure is such that water flows into the ice storage tank 1b immediately below it. The ice storage tanks 1c and 1d immediately below are filled and filled with water, respectively.

FIG. 5 shows an embodiment of the overflow port 2 cut along the line AA 'in FIG. Since the notch 8 is bent as shown in the figure, when the tank is full, water flows through the notch portion through the outer side surface 5 through 6 and 7. Since the outer side surface is inclined, water can be injected into the ice storage tank 1b immediately below without scattering to the outside.

Thus, whether or not the ice storage tank group 12 is full by the water injection means 13 is completed by detecting the water detecting sensor 11 and turning off the solenoid valve 14.

[0010]

According to the effect of the present invention, since the ice storage tank can be completely filled with water, the space efficiency is good. 80 in the tank
% Or more can be easily satisfied. Furthermore, since the entire ice storage tank group can be completely filled with water only by attaching the water injection means to the uppermost part, water can be injected after all the ice storage tanks are assembled, so that there is an effect that workability is good.

Since the outer side surface 5 of the ice storage tank is used, the lower ice storage tank is relatively gently poured into the ice storage tank and is hardly scattered.

A notch is formed in the steel plate, and the notch is pressed and bent to form an overflow port. Therefore, the steel plate can be manufactured without any trouble.

[0013] Since one sheet is roll-formed, it can be mass-produced inexpensively and efficiently. Moreover, since the plating treatment is performed, it is strong against rust and durable. In addition, they can be stacked and transported, which is effective in saving space during transportation.

In the present invention, when replenishing water in the ice storage tank,
All can be performed automatically, and maintenance is excellent.

As described above, the present invention can provide an inexpensive, durable and space-saving ice storage tank as the low-temperature and high-humidity storage system for vegetables and the like becomes large-scale. When the storage device is widely used, the effect of mass production of the storage device can be considered to reduce costs.
