The present invention relates to a water container, and more particularly, to a storage container of a hot water system.

Hot water storage systems often use containers with a hot water outlet at the top and an inlet at the bottom to receive the amount of hot water discharged.

In such an arrangement, slightly less specific hot water forms an isolation layer and is placed in the cold water level. There is a tendency for heat to be transferred from hot water to cold water by conduction through the container wall, but this can be eliminated by the container wall having a large amount of insulator installed inside. In addition, although heat tends to be conducted directly through the water itself, the main cause of hot water cooling by cold water is turbulence caused by inlet cold water.

Since the efficiency of a hot water storage container depends on avoiding mixing cold water and hot water in the container as much as possible, it is desirable to minimize the flow of water supplied into the container by the incoming cold water. The main purpose of the present invention is to provide an inlet structure for the storage container so that the influent can flow in the container with minimal disturbance movement at the confluence between the hot and cold water in the container and little effect on stratification.

According to the present invention, a water container 1 including an inlet device and an outlet device is provided, and the inlet device includes a first open end 5 and a second closed end arranged to enter water. 6) an inner tubular member 3 having a plurality of holes 7 along its length and an outer tubular member surrounding an inner conduit member and having an opening 8 along its length; , 4).

In particular, the inner conduit member 3 can be arranged such that the spacing between the openings 7 from the open end 5 gradually increases with respect to a given length of the inner conduit member. Moreover, the outer conduit member 4 can be arranged with the closed end adjacent to the closed end 6 of the inner conduit member 3 such that the opening at its outlet is directed downward in the generally assembled position.

According to a particular type of the invention as shown in the accompanying drawings, the inlet structure is composed of an inner conduit member 3 having one end closed and the other end having an outer diameter of 3/4 inch (19.05 mm) in length. Is provided. The member has an open end 5 protruding through a side wall or end wall near the bottom and is inserted into the reservoir and is connected to the cold water source by screwing, flaring or other suitable coupling. This member is arranged so as not to touch the opposite wall of the container. Thus, in a cylindrical tank measuring 1600.2 mm (60 inches) in length, its member (3) placed horizontally on the shaft is about 304.8 mm so that about 1270 mm (50 inches) emerges from one end wall into the vessel and does not touch the opposite end wall. (1ft) away The member is also provided with a series of conveniently formed holes 7 which are completely radially drilled through the tube, with some of the holes extending horizontally and others vertically.

Although it is desirable for the gap to be reduced again towards the closed end 6, it is generally desirable for the holes to be closer to each other near the inlet end 5 and the gap to be gradually larger towards the closed end 6. . The satisfactory spacing of the holes 7 from the wall near the inlet end 5 in one arrangement is 63.5 mm (2-1 / 2 inch), 57.15 mm (2-1 / 4 inch) and 85.73 mm (3-3 / 8 inch), respectively. ), 142.88 mm (5-5 / 8 inch), 165.1 mm (6-1 / 2 inch), 263.53 mm (10-3 / 8 inch), 155.58 mm (6-1 / 8 inch), and 222.25 mm (8-3 / 4 inch) It has been found that a gap of 3-1 / 8 inch (79.38 mm) or more is left with respect to the closed end 6 of the member. In this latter arrangement, the first, fifth, seventh and eighth holes are drilled vertically and the rest are drilled horizontally.

The special form of the present invention also includes an outer conduit 4 made of a tube which is closed at one end and slightly shorter than the size of the inner member 3 in the storage container and whose outer diameter is 38.1 mm (1-1 / 2 inch). . The outer conduit member 4 is assembled to the inner conduit member so as to coaxially surround the closed end of the outer member with or adjacent the closed end 6 of the inner member 3.

The outer conduit member 4 has a notch cross section 8 cut into a series of V-shapes on the wall to allow communication between the inside and the outside, all of which are notably supported on the inner member. It is arranged in a row on the lower side of the outer member. Each notch has a 60 ° angle and a width of 15.88 mm (5/8 inch) by 12.7 mm (1/2 inch) deep at the bottom.

The arrangement of the holes 7 of the inner conduit member 3 is as above, but the arrangement of the outer conduit member 94 is notched with a gap of about 43.93 mm (1-3 / 8 inch) between its open end and the wall of the tank. The spacing of the 8 is gradually 79.38 mm (3-1 / 8 inch), 130.18 mm (5-1 / 8 inch), 152.4 mm (6 inch), 114.3 mm (4-1 / 2 inch), 114.3 mm (4) -1/2 inch), c 387.35 mm (15-1 / 4 inch) and 130.18 mm (5-1 / 8 inch), and are arranged so that a gap of 111.13 mm (4-3 / 8 inch) or more remains with respect to the closed end wall.

It can be seen at the particular spacing mentioned above that most of the kinetic energy of the water entering the inlet device is used, and the water flows through the holes in the inner member into the space between the inner and outer members, and then generates very little disturbance. It swings through the notch in the outer member and the open end therein in a protruding manner, so that little splitting occurs in the layer of water at the point of separation between the two thermal zones.

In the actual experiment using the special arrangement described above it was found that the entire volume in the storage tank could be withdrawn before the water temperature was reduced to any indicated size.

Claims (1)

In the inlet device for a water container, the inlet device comprises an inner conduit member 3 located in the water container 1 and an outer conduit member 4 surrounding the inner conduit member 3, wherein the inner conduit The member 3 has a plurality of openings 7 extending horizontally and vertically along its length and having a first open end 5 and a second closed end 6 protruding through the side wall and connected to a cold water source. The outer conduit member 4 is slightly shorter than the size of the inner conduit member 3 and is arranged in a row at the lower side thereof so that the V-shaped opening 8 can communicate with the inside and the outside.
