Description

Gravity Backflow Prevention Device {The hold in check device to upstream current by gravity}

The present invention is located inside the hot water tank (10) of the cold, warm water purifier or cold, water heater,

As a device for preventing the back flow of hot water,

More specifically, the heated water of the hot water tank 10 using gravity

Heat exchange with the reservoir 4 of the reservoir 6 through the hot water inlet 14

To save energy, and to save hot water

A device for feeding.

Generally, water or liquid, such as cold or warm water

In devices that need to supply cold and hot at the same time through heating and cooling

Heat exchange between cold and hot leads to energy loss and cold and cold effect reduction

We have struggled with measures to prevent heat exchange while ensuring continuity of flow.

As shown in Figure 1, the inlet (2) to the water or liquid supplied from the outside

When collected in the reservoir (6) through the reservoir (4) by the cold water import pipe (12)

Flow into the cold water tank (8) and the hot water tank (10) at the lower portion through the hot water inlet pipe (14)

The structure to be entered has been used to date.

This structure is heated by heating the water in the hot water tank (10)

And heat exchange with the reservoir 4 of the reservoir 6 through the hot water inlet pipe 14.

The heating energy of the hot water tank (10) is achieved in the reservoir (4) of the reservoir (6)

Since the result is delivered to keep the water in the hot water tank 10 to a certain temperature

In order to continuously supply more energy than the heat exchanged energy.

It was possible.

In addition, the reservoir 4 of the reservoir 6 is connected to the cold water tank 8 through the cold water inlet pipe 12.

As it is connected, the energy for cooling the cold water tank 8 is further increased.

It has resulted in increased waste of energy.

The example shown in Figure 2 is a structure used so far in cold and hot water,

Water heated in the hot water tank (10) rises up the hot water inlet pipe (14)

When it reaches the surface of the reservoir 4 of the reservoir 6 beyond the separation plate 18, it enters the external bucket 20.

Heat exchange is carried out in the stored water, and the cold water under the separator plate 18

The structure reduces the effect of heat exchange.

However, the heat of the hot water tank 10 is discharged to the atmosphere through the surface of the external water tank 20

There is a lot of energy loss, and the energy which is not released is stored in the reservoir 4 of the reservoir 6

Since it flows in, it transmits heat energy to the cold water under the separator 18.

It has been a source of energy waste.

The purpose of the present invention is to provide cold and hot water, such as cold and warm water

In the device to be manufactured and supplied at the same time, the heated hot water of the hot water tank (10)

Do not heat exchange with the reservoir (6), the heating of the hot water tank (10)

By releasing the inflation pressure by gravity, reducing energy loss

Gravity type that can easily rise to the point of breaking the internal temperature of the hot water tank (10)

It is to provide a backflow prevention device.

According to the present invention, cold and hot water, such as cold, warm water or cold, hot water

In the apparatus that must be manufactured and supplied at the same time, the heated hot water of the hot water tank 10

No heat exchange with the reservoir 4 of the reservoir 6 and no expansion pressure

Gravity backflow prevention device to minimize energy loss to break point

Is provided.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention

As follows.

3 is a cold, warm water purifier or gravity type backflow prevention device according to the present invention

This is an example applied to the general structure of cold and hot water.

The water or liquid supplied by the filter or pump is passed through the inlet (2).

Collected in the reservoir (6) by the cold water import pipe (12)

The hot water inlet 26 flows into the cold water container 8 and the hot water container 10.

The water or liquid collected in the cold water tank 8 is cooled by the refrigerant pipe 16 on the outer wall.

Fall, and the specific gravity is increased to build up in order from the bottom of the cold water tank (8)

Although the heat exchange with the reservoir 4 is very small, the water or liquid in the hot water tank 10

As a result, the specific gravity decreases and rises upward.

At this time, thermally separated from the reservoir 4 of the reservoir 6 by the heat insulation separation tube 24

Pressure tube 22 attached to the uppermost part of the hot water tank 10 is above the water level of the reservoir 4

When positioned, the water level of the hot water tank 10 is equal to the reservoir 4 by atmospheric pressure.

In this form, the water or liquid in the hot water tank (10) exchanges heat with the reservoir (4).

Since it becomes difficult, the heat energy of the hot water tank 10 is reduced.

In addition, the pressure generated by the internal temperature of the hot water tank 10 is increased.

Since it is released through the pressure pipe 22, the internal pressure of the hot water tank 10 is always constant

It is possible to maintain, which is also effective in structural stability.

The gravity backflow prevention device is a cold or hot water purifier as described above

As cooling and heating coexist like cold and hot water,

In devices with continuous structures, losses of thermal energy and

Provides an optimal choice to minimize unnecessary pressure generation.

In addition, the internal temperature of the hot water tank 10 is maintained for a long time by minimizing heat loss.

It is possible.

According to the present invention as described above, the gravity backflow prevention device

It can be applied to devices or appliances to minimize the loss of thermal energy and save electricity.

It can avoid the heat and cold interference and maximize the efficiency
