Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water tank for storing articles that require refrigeration, such as a trough, and more particularly to a water tank in which an article placement plate provided in the tank can be moved up and down.

In the past, items that needed to be stored in cold water, such as troughs, were placed in deep tanks, but in such tanks, it was necessary to reach deep into the water to remove items that had been sunk to the bottom of the tank. The work was difficult, especially in the winter.

For this reason, recently, for example,
As disclosed in Japanese Patent No. 26369, an article placement plate is provided in a water tank, the article placement plate is attached to a telescopic bellows, and water is introduced into or discharged from the bellows to place an article. A water tank with a mounting plate that can be moved up and down has been developed.

However, in a vertical movement device using such a bellows that has free flexibility, when the articles are unevenly distributed on the article placement plate, the bellows does not expand and contract in a straight line in the vertical direction. Therefore, there is a drawback that the mounting plate tilts in the water, and the article to be taken out remains deep in the water.

Therefore, the purpose of the present invention is to use a nested device that expands and contracts vertically in a straight line as a device for moving the article table up and down, so that the table plate will not be tilted even if the articles on the table are unevenly distributed. The objective is to provide a refrigerated water tank with

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 shows an aquarium 10 consisting of a box with an open top, which is filled with water 12 to the desired level.

At the center of the water tank 10, a nested cylindrical member 14 that extends from multiple stages is arranged.

A screw is provided on the outer peripheral surface of the lower end of the lowermost element 16 of the cylindrical member 14, and the screw engages with a screw provided on the inner peripheral surface of a fixture 20 fixed to the bottom 18 of the water tank 10, A cylindrical member 14 is fixed to the bottom 18 of the aquarium 10.

A water supply and drainage port 22 is provided in the center of the fixture 20 for supplying and discharging tap water into the cylindrical member 14.
The water supply and drainage port 22 extends to the outside of the tank through a hole provided in the bottom of the tank.

A water supply/drainage port 22 is connected to a water pipe 26 via a water supply valve 24 and to a drain pipe 3 via a drain valve 28 outside the ice tank 10.
Connected to 0.

At the top of the uppermost element 32 of the cylindrical member 14 is an article 33
An article placement plate 36 for placing items (for example, troughs, etc.) is fixed by screws 34.

It is desirable to provide an appropriate number of holes 38 in the article placement plate 36 in order to reduce the resistance force received from water when the article placement plate 36 moves up and down in water.

FIG. 1 shows the cylindrical member 14 in its most extended position.

The cylindrical member 14 is extended by closing the drain valve 28 and then opening the water supply valve 24 to allow tap water from the water pipe 26 into the cylindrical member 14.

At this time, in order to prevent the cylindrical member 14 from elongating beyond a predetermined length, each stage element of the cylindrical member is provided with a shoulder portion 40 and an inwardly protruding portion 42 for engaging adjacent elements. It is.

The inner circumferential surface and the outer circumferential surface of each stage of the cylindrical member 14 of the aquarium according to the present invention have a length of "°" with respect to the adjacent element, respectively.
Since the cylindrical member 14 has a sufficient support surface that is tightly fitted to form a water-tight engagement with the cylindrical member 14, even when objects are placed unevenly on the mounting plate 36, the cylindrical member 14 as a whole remains in a straight line. Since it expands and contracts in the vertical direction, the mounting plate 36 does not tilt.

To contract the expanded cylindrical member 14, the water supply valve 2
4 and then open the drain valve 28 to remove the cylindrical member 14.
This is done by draining the water from the drain pipe 30.

At this time, the water in the cylindrical member 14 is removed from the mounting plate 36 and the article 3.
3 is discharged from the drain pipe 30 under pressure due to the weight of the tank. In order to perform this discharge operation more quickly and reliably, a tension spring (not shown) is installed between the lower surface of the mounting plate 36 and the bottom 18 of the tank. It is preferable to provide a cylindrical member (1) or, as shown in the figure, to increase the weight by making the uppermost element 32 of the cylindrical member 14 a solid member so that water within the cylindrical member can be actively drained. .

FIG. 2 shows the aquarium cylindrical member 14 according to the present invention in a completely retracted state.

As shown in the figure, the heights htt of the elements on each stage of the cylindrical member 14 are all set to the same height, and the area supporting the mounting plate 36 when the cylindrical member is completely contracted increases, so that articles can be more stably stored. can be placed.

As described above, the device for vertically moving the mounting plate of a refrigerated water tank according to the present invention uses a cylindrical member with a cylindrical shape, and the elements of each stage of the cylindrical member are adjacent to each other with a sufficiently long sliding contact area. Since it is in contact with the element, a sufficient supporting capacity can be obtained, and even if the articles on the mounting plate are unevenly distributed, the mounting plate can be moved up and down without tilting.
