Abstract

This invention relates to the constant temperature water supply system which keeps the temperature of the water from the tap for hot water constant.
It consists of a cold and hot water storage tank, a water supply pipe from a cold and hot water storage tank to a water tap, a recovery pipe from a water tap to a hot water storage tank, and a valve, a water tap, and a water supply pump with no change in water pressure regardless of the operation of the valve.
The water consumed until a suitable temperature of water comes out is saved, and the hot water waiting in the water supply pipe while the tap is closed is prevented from cooling. The correct temperature of water is always available, making the user comfortable.

Description

Constant Water Suppply System

It is a system that maintains a constant temperature of water coming out of a hot and cold tap or shower head.

When you wash your face in the sink or shower, it takes time to set the water temperature. Even if you adjust the hot water to come out, the water filled in the hot water pipe may be cool, or if you are using water elsewhere, cold water comes out. If you take out the water for a while, the water of the desired temperature comes out, or if you use hot water elsewhere while you are using the water of the desired temperature, the temperature of the water suddenly changes. All of this is a source of waste of water and energy.

The hot water supply pipe stopped at the water tap is extended to the hot water storage tank so that the hot water flows through the water tap to the hot water storage tank at all times, and the water control valve of each tap changes the water pressure regardless of the operation of the valve. A valve without a valve is adopted so that the amount of water supplied is always equal to the sum of the amount of water discharged through the tap and the amount of water returned to the return pipe.

The water consumed until the right temperature is reached (about 12 liters per minute in the case of a shower facility) and the hot water in the water supply line is prevented from cooling while the tap is closed. The correct temperature of water is always available, making the user comfortable.

1 is a system diagram illustrating the principle of the present invention.
2 is a cross-sectional view of the three-way valve.

This invention relates to the constant temperature water supply system which keeps the temperature of the water discharged from the tap for cold / hot water constant.

It demonstrates concretely with drawing.

1 is a schematic diagram showing the interrelation of each component for explaining the contents of the present invention.

Hot water supplied from a recovery water tank 1 having a heater and a power supply (not shown) and a water supply pump 2 is stored in the hot water tank 4 through a supply pipe 3. The recovery water tank 1 is located below the tap water 6, and the recovery water tank is equipped with a thermometer 8 and the hot water tank with a water gauge 9.

When the tap water is turned by turning the handle for adjusting the hot water of the three-way valve 10 having three pipes (not shown) and the flow regulating handle of the faucet (6), the water of the hot water tank (4) and the cold water tank (5) The sum is discharged to the water tap 6. Of the hot water supplied through the hot water supply pipe (3), the remaining water discharged to the tap water is recovered to the recovery water tank (1) through the recovery pipe (7). The hot water tank may be installed with a constant pressure pump.

The three-way valve 10 is equal to the cross-sectional area of the inlet pipe 12 into which the hot water is introduced, equal to the area of the two outlet pipes 13 and 14 from which the hot water is discharged, minus the area blocked by the water plate 11. Since the flow of water is free fall through the recovery pipe 7, the hot water discharged to the tap water 6 has no fluctuations in the water pressure and the flow rate of the inlet pipe and the discharge pipe regardless of the position of the index plate 11, Since there is no time for the hot water to circulate continuously, the temperature of the hot water is always constant. You will always be able to use the correct temperature water.

2 is a cross-sectional view of the three-way valve 10, and is a diagram of a process of varying the position of the index plate 11 inside the valve by adjusting the hot water control valve.

The three-way valve structure has one inlet pipe 12 and two outlet pipes 13 and 14 connected to the casing, and the outlet of the inlet pipe side and the first discharge pipe 13 or the second discharge pipe 14 side is entirely inside. Or the water stop plate 11 which can block a part is assembled by the structure which moves left and right by the handle operated from the outside. The cross-sectional areas of the inlet pipe 12 and the two outlet pipes 13 and 14 are the same.

2-a shows a state in which the first discharge pipe 13 is completely closed and the second discharge pipe 14 is unfolded, and all of the warm water flowing in is discharged to the water tap 6.

2-b is a view of the state in which the first discharge pipe 13 is developed and the second discharge pipe 14 is completely closed, and all of the hot water introduced is discharged to the recovery water pump 1.

2-c is a state in which the first discharge pipe 13 and the second discharge pipe 14 are half-opened, and the incoming hot water is discharged into the water tap (6) half and into the recovery water tank (1). The sum of the areas of the open parts of the discharge pipe is always half the cross-sectional area of the two discharge pipes.

As described above, according to the constant temperature water supply system according to the present invention, when the handle is fixed at an appropriate position, hot water at a constant temperature is always discharged at a constant flow rate. When you wash your face in the sink or take a shower, the above conditions are valid even if you are using water from another tap.
