Description

[Detailed explanation of the invention] In the present invention, a water tank 3 is provided at the upper part of the upright cylinder 2, the lower part communicates with the boiler combustion chamber 11, and an upright inner smoke tube 2 concentric with the cylinder 2 is located inside the cylinder 2. is inserted into the upper end of the same type of smoke tube 2 and communicates with the horizontal direction changeable smoke tube 2' which penetrates through the middle of the same type 3,
An ascending water channel 1 is provided in the gap between the cylinder 2 and the smoke cylinder 2', communicating with the bottom of the cylinder 3, and a water intake port 4 is provided on the side surface of the middle part of the cylinder 3, which passes through the water supply port 21 of the boiler 11. And same kind 3
A cold water chamber 6 partitioned by a partition wall 5 is provided inside the chamber, the bottom of the chamber 6 communicates with the lower part of the passage 1, and an automatic cold water faucet 8 with a float 7 is opened at the top of the cold water chamber 6. This relates to a water supply system for a boiler.

The upright cylinder 2 consists of an upright inner smoke tube 2〃 and an outer tube 2'', and the passage 1 is formed by the gaps 2N and 2''.

As shown in the figure, the horizontal direction changeable smoke cylinder 2' changes direction in the horizontal direction, and its upper surface is supported directly below the water intake port 4 and the water surface 9.

The water storage tank 3 and the cold water chamber 6 are communicated through a pipe 10, and the water surfaces 9, 9' of the water tank 3 and the cold water chamber 6 are at the same level.

The automatic cold water faucet 8 is nothing but a so-called system tank faucet that opens and closes by raising and lowering a float 7 floating on the water surface 9 or 9'.

In the figure, reference numeral 11 indicates a hot water boiler, and reference numeral 12 indicates an exhaust port provided on the top surface of the boiler 11, into which the lower end of the upright smoke tube 2 can be removably fitted.

Further, 13 is a flange for attaching the lower end of the upright smoke tube 2, 14 is a screw for attaching the same, 15 is a drain pipe, 16 is an on-off valve provided on the drain pipe 15, 17 is a hot water supply pipe by the hot water boiler 11,
18 is a hot water tap 1; 19 is a vent pipe; 20 is a pipe that communicates the water intake port 4 with the water supply port 21 of the hot water boiler 11; 22 is a cold water supply pipe; 23 is an operating arm provided on the float 7; 24 is the same arm. 2
3 is a pivot pin, 25 is an opening/closing valve operated by the same arm 23, and 26 is a water passage hole.

Therefore, when the water storage tank 3 and the cold water chamber 6 are filled with cold water, the hot water boiler 11 is also filled with cold water.

When the hot water tap 18 is opened, the hot water boiler 11 automatically ignites and heats the cold water in the boiler 11.
Hot water can be supplied from 8.

Exhaust heat from the boiler 11 rises from the exhaust port 12 through the upright chimney 2 and is exhausted to the outside from the redirection chimney 2'.

Such rising exhaust heat heats the water in the passage 1 and raises its temperature, and also heats the water in the water tank 3, so that the temperature of the water in the same kind 3 also rises.

The cold water in the cold water chamber 6 descends through the piping 10, ascends through the passage 1, is heated, rises to near the water surface 9 of the water storage tank 3, passes from the water intake 4 through the piping 20, and flows from the water inlet 21 of the boiler 11 to the boiler 11. Hot water is supplied inside the boiler, the temperature of the same hot water is further increased by heating by the boiler 11, and hot water is supplied from the hot water tap 18.

Therefore, when the water surface 9, 9' falls, the float I descends, the cold water supply tap 8 opens, and cold water is supplied to the cold water chamber 6, and the water surface 9, 9'
The operation of stopping the supply of cold water when the float 7 rises is repeated.

Since the present invention is configured as described above, the temperature of the water supplied to the hot water boiler 11 is increased, and the increased heat is replenished by the exhaust heat of the boiler 11, which has the advantage of significantly improving the thermal efficiency of the boiler 11.
