Description

Hot water circulation device using steam pressure

The present invention relates to a hot water circulation device using vapor pressure, and more particularly, it uses vapor pressure to supply hot water using vapor pressure, to prevent overheating of a tank, and to prevent steam from flowing into a heat exchanger. It relates to the hot water circulation system.

In general, a hot water circulation device such as a hot water mat is used for the purpose of heating.

Such a hot water circulation device installs a hot water pipe in the mat, circulates the hot water in the pipe to heat the mat, and a mechanical configuration such as a circulation motor is used to circulate the hot water.

However, in the case of a mechanical configuration such as a circulation motor, electricity or a battery is required, and there is a disadvantage that not only generates noise, but also frequently breaks down due to deterioration of the motor when used for a long time.

Accordingly, recently, in order to solve the problem of the hot water circulation system using the existing circulation motor, a hot water circulation system using steam pressure that can continuously supply hot water by a heat source without using electricity or a battery has been developed. It is disclosed in No. 2016-089991 (hereinafter referred to as 'conventional hot water circulation device using vapor pressure').

1A and 1B are schematic views of a hot water circulation device using a conventional vapor pressure.

As shown in FIGS. 1A and 1B, the conventional hot water circulation device using vapor pressure includes a first tank 110 having an accommodating space 111 in which water is accommodated, and the first tank 110 is installed under the inside The second tank 120 in which the heating space 121 is formed, one end communicates with the receiving space 111 and the other end communicates with the heating space 121 so that the water accommodated in the receiving space 111 is heated in the heating space ( 121), a water inlet pipe 130 guiding it to be obtained, a heating means 140 installed under the second tank 120 to heat the water contained in the second tank 120, and one end of the second tank 120 ) connected to the lower side of the water outlet pipe 150 and the other end connected to one end of the heat exchanger (H) disposed in the heating area, and the water inlet pipe 130 and the water outlet pipe 150 are respectively installed on one side The check valve 160 and one end are connected to the other end of the heat exchanger (H), and the other end is composed of a return pipe 170 communicating with the receiving space 111 of the first tank 110 .

And, as the water in the second tank 120 is heated by the heating means 140, steam is generated, and as the pressure of the second tank 120 is increased by the generated steam, the inlet pipe 130 side check valve ( 160) is closed.

Next, as the pressure in the second tank 120 is continuously increased, the water in the second tank 120, that is, the hot water generated by heating the water moves to the heat exchanger H through the outlet pipe 150, The heating zone is heated by exchanging heat with the heating zone through the heat exchanger (H).

Thereafter, the hot water passing through the heat exchanger H flows into the first tank 110 through the recovery pipe 170 and repeats the above operation.

However, in the conventional hot water circulation device using vapor pressure, when the pressure in the second tank 120 is lowered to a predetermined pressure or less, the check valve 160 on the inlet pipe 130 side is opened so that water can be continuously supplied, To this end, hot water is discharged through the water outlet pipe 150, and the remaining steam is also discharged, so that the vapor pressure must be extinguished.

5 is a view showing a state in which water located in the upper space flows into the lower space according to the first embodiment of the present invention, and FIG. 6 is a state in which the opening/closing means according to the first embodiment of the present invention shields the through hole. 7 is a view showing a state in which hot water is discharged through the outlet according to the first embodiment of the present invention, and FIG. 8 is a low pressure in the lower space according to the first embodiment of the present invention. It is a diagram showing a state in which water flows into the lower space while the water is falling.

The operation of the hot water circulation device 1 using vapor pressure according to the first embodiment of the present invention having such a configuration will be described with reference to the accompanying FIGS. 5 to 8 as follows.

First, the water level in the lower space 11 is low, and the float 51 is positioned to be supported by the stopper 53b, so that the user pours water into the upper space 11a while the opening/closing unit 52 opens the through hole 21. When supplied, water in the upper space (11a) flows into the lower space (11b) through one side of the open through hole (21), and the steam or air existing in the lower space (11b) passes through the other side of the through hole (21). It flows out into the upper space (11a).

When water flows into the lower space 11b and the water level rises, and the float 51 rises together to reach the opening/closing unit 52, the opening/closing unit 52 is pressed in the direction of the upper space 11a by buoyancy ( 21) is shielded.

When the through hole 21 is blocked, the inflow of water into the lower space 11b is stopped, and the user stops supplying water when the water is filled in the upper space 11a.

After that, when the heating means 30 is operated and the lower space 11b is heated, the temperature of the water in the lower space 11b rises, and when the boiling point is reached, steam is generated to increase the pressure in the lower space 11b. .

When the pressure in the lower space 11b increases, the outlet-side check valve 14 is opened and the hot water generated in the lower space 11b is discharged to the heat exchanger 40 through the outlet 13 . At this time, the temperature of the hot water moved to the heat exchanger 40 becomes the boiling point.

The hot water discharged to the heat exchanger 40 exchanges heat with the heating area and then flows into the upper space 11a through the inlet 12 .

When the water in the lower space 11b is discharged, the water level in the lower space 11b is lowered, and the float 51 descends together. At this time, even if the float 51 descends and does not press the opening/closing unit 52 upward, the pressure in the lower space 11b acts on the opening/closing unit 52, so that the opening/closing unit 52 blocks the through hole 21 The state is maintained, and hot water is continuously discharged to the heat exchanger 40 .

After that, when the float 51 continues to descend to reach the stopper 53b, the gravity of the float 51 is applied downward to the stopper 53b, and the opening/closing unit 52 is moved downward so that the through hole 21 is forced to open

The steam of the lower space 11b is discharged to one side of the open through hole 21 and condensed or discharged to the atmosphere while passing the water in the upper space 11a, and the other side of the through hole 21 is from the upper space 11a. Low-temperature water flows into the lower space 11b.

Since the water in the lower space 11b is maintained below the boiling point while the water flows into the lower space 11b, no steam is generated even if the water in the lower space 11b is continuously heated.

When water flows into the lower space 11b and the water level rises, the float 51 rises and presses the opening/closing unit 52 upward with buoyancy, the through hole 21 is blocked and the water inflow is stopped.

In this state, the heating of the lower space 11b continues, and when the temperature of the water in the lower space 11b increases and steam is generated and the pressure increases, the check valve 14 on the outlet side is opened and the lower space ( The hot water of 11b) is discharged to the heat exchanger 40 through the outlet 13 .

By repeating this process, the water cycle continues.

9 is a view showing a state in which water is introduced into the lower space according to the second embodiment of the present invention, and steam or air in the lower space is discharged to the upper space, and FIG. 10 is a second embodiment of the present invention. It is a view showing a state in which the opening and closing means according to the shielding the through hole.

The basic configuration of FIGS. 9 and 10 is the same as the embodiment of FIGS. 2 to 8 , but further includes a pipe body 70 through which water from the upper space 11a flows into the lower space 11b.

The tube body 70 is coupled to the bottom surface of the partition means 20 so that the upper end communicates with the upper space 11a, and is formed to extend downward, and when the pressure in the lower space 11b is less than a preset pressure, the tube body 70 is opened. A check valve 71 is provided.

The operation of the hot water circulation device 1 using the vapor pressure according to the second embodiment of the present invention having such a configuration is as follows.

Prior to the description, the tank 10 is initially empty, the float 51 is positioned to be supported by the stopper 53b, the opening/closing unit 52 opens the through hole 21, and the check valve 14 on the outlet side and the tube side check valve 71 are assumed to be in an arbitrary state.

When a user supplies water to the upper space 11a, the water opens the pipe-side check valve 71, passes through the pipe 70, and flows into the lower space 11b.

Steam or air existing in the lower space 11b while the water is introduced is discharged to the upper space 11a through the through hole 21 to be condensed or discharged to the atmosphere.

When water flows into the lower space 11b and the water level rises, and the float 51 rises to reach the opening/closing unit 52, the opening/closing unit 52 is pressed by buoyancy to block the through hole 21.

When the through hole 21 is blocked, the inflow of water into the lower space 11b is stopped, and the user stops supplying water when the water is filled in the upper space 11a.

After that, when the heating means 30 is operated and the lower space 11b is heated, the temperature of the water in the lower space 11b rises, and when the boiling point is reached, steam is generated to increase the pressure in the lower space 11b. .

When the pressure in the lower space 11b increases, the tube-side check valve 71 is closed, the outlet-side check valve 14 is opened, and the hot water generated in the lower space 11b passes through the outlet 13 through the heat exchanger. (40) is discharged.

The hot water discharged to the heat exchanger 40 exchanges heat with the heating area and then flows into the upper space 11a through the inlet 12 .

When the water in the lower space 11b is discharged, the water level in the lower space 11b is lowered, and the float 51 descends together. At this time, even if the float 51 descends and does not press the opening/closing unit 52 upward, the pressure in the lower space 11b acts on the opening/closing unit 52, so that the opening/closing unit 52 blocks the through hole 21 The state is maintained, and hot water is continuously discharged to the heat exchanger 40 .

After that, when the float 51 continues to descend together with the water level in the lower space 11b to reach the stopper 53b, the gravity of the float 51 is applied downward to the stopper 53b, and the opening/closing unit 52 opens. The through hole 21 is forcibly opened by moving downward.

The steam of the lower space 11b escapes through the open through hole 21 and is condensed or discharged to the atmosphere while passing through the water in the upper space 11a.

Then, when the vapor of the lower space 11b is discharged and the pressure is lowered, the outlet side check valve 14 is closed, the tube side check valve 71 is opened, and the water in the upper space 11a is discharged to the tube body 70 It is introduced into the lower space (11b) through the.

Since the water in the lower space 11b is maintained below the boiling point while the water flows into the lower space 11b, no steam is generated even if the water in the lower space 11b is continuously heated.

When water flows into the lower space 11b and the water level rises, the float 51 rises together and presses the opening/closing unit 52 upward with buoyancy, and the opening/closing unit 52 blocks the through hole 21 and water inflow is stopped.

In this state, as the heating of the lower space 11b continues, the temperature of the water in the lower space 11b increases, and when steam is generated and the pressure increases, the tube-side check valve 71 is closed, and the outlet-side check valve (14) is opened, the hot water in the lower space (11b) is discharged to the heat exchanger (40) through the outlet (13).

By repeating this process, the water cycle continues.

* Fig. 11 is a view showing a state in which water flows into the lower space from the upper space according to the third embodiment of the present invention, and Fig. 12 is a state in which the opening and closing means according to the third embodiment of the present invention shields the through hole is a diagram showing

The basic configuration of FIGS. 11 and 12 is the same as the embodiment of FIGS. 9 and 10 , but a spiral heating pipe 60 is added so that water flowing in from the upper space 11a passes through the heating pipe 60 to the lower part. By introducing the steam into the space 11b and heating the heating pipe 60 to the lower space 11b, steam can be rapidly generated, and the hot water discharged from the lower space 11b is maintained below the boiling point. It is structured in a way that can be

One end of the heating pipe 60 of this embodiment passes through one side of the tank 10 and is connected to the tube body 70 , and the other end passes through the other side of the tank 10 and is higher than the highest water level of water accommodated in the lower space. placed in the same or higher position.

In this embodiment, the heating pipe 60 is disposed at a position corresponding to the heating means 30, and is preferably formed in a spiral shape in order to increase heat transfer efficiency.

The operation of the hot water circulation device 10 using the vapor pressure according to the third embodiment of the present invention having such a configuration is as follows.

Initially, the tank 10 is empty inside and the float 51 is positioned to be supported by the stopper 53b so that the opening/closing unit 52 opens the through hole 21, and the outlet side check valve 14 and the tube side check valve (71) is in an arbitrary state.

Here, when the user supplies water to the upper space 11a, the water opens the check valve 71, passes through the heating pipe 60, and flows into the lower space 11b.

Steam or air existing in the lower space 11b while the water is introduced is discharged to the upper space 11a through the through hole 21 to be condensed or discharged to the atmosphere.

When water flows into the lower space 11b and the water level rises, and the float 51 rises to reach the opening/closing unit 52, the opening/closing unit 52 is pressed by buoyancy to block the through hole 21.

Accordingly, when the inflow of water into the lower space 11b is stopped and the water is filled in the upper space 11a, the water supply is stopped.

Then, when the heating means 30 is operated to heat the heating pipe 60, the temperature of the water in the heating pipe 60 rises, and when the boiling point is reached, steam is generated.

When steam is generated in the heating pipe 60 and the internal pressure is increased, the tube-side check valve 71 is closed and the generated steam is introduced into the lower space 11b.

When steam is continuously introduced into the lower space 11b and the internal pressure increases, the outlet-side check valve 14 is opened, and the water in the lower space 11b is discharged to the heat exchanger 40 through the outlet 13 . do.

The hot water discharged to the heat exchanger 40 exchanges heat with the heating area and then flows into the upper space 11a through the inlet 12 .

When the water in the lower space 11b is discharged, the water level in the lower space 11b is lowered, and the float 51 descends together. At this time, even if the float 51 descends and does not press the opening/closing unit 52 upward, the pressure in the lower space 11b acts on the opening/closing unit 52, so that the opening/closing unit 52 blocks the through hole 21 The state is maintained, and hot water is continuously discharged to the heat exchanger 40 .

After that, when the float 51 continues to descend and the float 51 reaches the stopper 53b, the gravity of the float 51 is applied downward to the stopper 53b, and the opening/closing unit 52 is moved downward. The through hole 21 is forcibly opened.

The steam of the lower space 11b is discharged through the open through hole 21 and condensed while passing through the water of the upper space 11a or discharged to the atmosphere.

When the steam is discharged and the pressure in the lower space 11b is lowered, the outlet side check valve 14 is closed, the tube side check valve 71 is opened, and low-temperature water from the upper space 11a is heated through the heating pipe 60 is introduced into the lower space 11b through the At this time, the high-temperature water remaining in the heating pipe 60 is mixed with the incoming low-temperature water and flows into the lower space 11b.

Since the heating pipe 60 and the lower space 11b are cooled and maintained below the boiling point while low-temperature water is introduced from the upper space 11a, no steam is generated even if the heating pipe 60 is continuously heated.

When water flows into the lower space 11b and the water level rises, the float 51 rises together and presses the opening/closing unit 52 upward with buoyancy, and the opening/closing unit 52 blocks the through hole 21 and water inflow is stopped.

In this state, when the heating of the heating pipe 60 continues and the temperature of the water in the heating pipe 60 increases, steam is generated, the pressure increases, and the outlet side check valve 14 is opened, and the lower space 11b ) of hot water is discharged to the heat exchanger 40 through the outlet 13 .

By repeating this process, the water cycle continues.

The basic configuration of FIGS. 13 and 14 is the same as the embodiment of FIGS. 9 to 10 , but additional partition means 80 and an overflow pipe 90 are added so that hot water below the boiling point is discharged to the heat exchanger 40 . It is formed in a structure that can be

13 and 14, the additional partitioning means 80 is formed to be inserted into the middle depth between the tank 10 and the partitioning means 20 in the shape of a container with an open upper portion, thereby forming the lower space 11b into the first space. It divides up and down into the part 11ba and the 2nd space part 11bb.

The additional partition means 80 has a communication hole 81 formed on one side, an overflow tube 90 is formed to extend upward of the communication hole 81, and the lower end of the tube body 70 is extended on the other side. 2 is coupled in communication with the space portion 11bb

The overflow pipe 90 is mixed with the hot water of the second space 11bb when the water of the upper space 11a flows into the second space 11bb through the pipe body 70 to form the first space ( 11ba) serves as a passageway

In addition, the overflow pipe 90 serves as a passage through which steam is introduced into the first space 11ba when steam is generated in the second space 11bb, and the steam flows into the first space 11ba. is formed in the shape of a chimney so that the water of the first space 11ba can be introduced into the upper part of the first space 11ba, that is, the gas phase without contacting it.

On the other hand, although the overflow pipe 90 according to this embodiment is shown as having an upper end spaced apart from the bottom surface of the partition means 20, the present invention is not necessarily limited thereto, and the upper end of the overflow pipe 90 is It may be formed in a structure in which the discharge hole 91 is formed at the upper end in close contact with the bottom surface of the partition means 20 .

The operation of the hot water circulation device 1 using the vapor pressure according to the fourth embodiment of the present invention having such a configuration is as follows.

Initially, the inside of the tank 10 is empty, the float 51 is positioned to be supported by the stopper 53b, the opening/closing unit 52 opens the through hole 21, and the outlet side check valve 14 and the tube side check The valve 71 is in an arbitrary state.

When the user supplies water to the upper space 11a, the water opens the check valve 71, passes through the tube body 70, and flows into the second space 11bb.

When the second space portion 11bb is filled with water, the first space portion 11ba is filled with water through the overflow pipe 90 .

Steam or air existing in the first space portion 11ba and the second space portion 11bb while the water is introduced is discharged into the upper space 11a through the through hole 21 to be condensed or discharged to the atmosphere.

When water flows into the first space 11ba and the water level rises, the float 51 rises together to reach the opening/closing unit 52, and pressurizing the opening/closing unit 52 with buoyancy to block the through hole 21 do.

When the through hole 21 is blocked, the inflow of water into the first space 11ba and the second space 11bb is stopped, and when the water is filled in the upper space 11a, the water supply is stopped.

Thereafter, when the heating means 30 is operated to heat the second space portion 11bb, the internal water temperature rises, and when the boiling point is reached, steam is generated.

The generated steam is introduced into the upper region of the first space 11ba through the overflow pipe 90 .

When steam is continuously introduced and the pressure of the first space portion 11ba increases, the tube-side check valve 71 is closed, the outlet-side check valve 14 is opened, and the water in the first space portion 11ba is opened. It is discharged to the heat exchanger 40 through the outlet 13 .

Water discharged to the heat exchanger 40 passes through the heat exchanger 40 and flows into the upper space 11a through the inlet 12 .

When the water in the first space 11ba is discharged, the water level decreases and the float 51 descends together. At this time, even if the float 51 descends and does not pressurize the opening/closing unit 52, the pressure in the first space 11ba acts on the opening/closing unit 52, so that the shielding state of the through hole 21 is maintained, and the hot water It is continuously discharged to the heat exchanger (40).

As described above, in the first circulation, unheated low-temperature water is filled in the first space 11ba, so low-temperature water flows into the heat exchanger 40, but from the second circulation, hot water is supplied to the first space ( 11ba), so hot water flows into the heat exchanger 40, which will be described in more detail below.

After that, when the float 51 continues to descend and reach the stopper 53b, the gravity of the float 51 is applied downward to the stopper 53b, and the opening/closing unit 52 is moved downward so that the through hole 21 is forced to open

The steam of the first space portion 11ba is discharged through the open through hole 21 and is condensed or discharged to the atmosphere while passing through the water of the upper space 11a.

When the steam is discharged and the pressure of the first space portion 11ba is lowered, the outlet side check valve 14 is closed and the tube side check valve 71 is opened, so that low-temperature water from the upper space 11a can be discharged into the tube body 70 ) through the second space 11bb.

On the other hand, when liquid water is changed to steam, since the volume is increased by about 1000 times or more, even if the steam generated by evaporation of the water in the second space 11bb pushes out all the water in the first space 11ba The water in the second space 11bb hardly decreases and remains at a high temperature.

Accordingly, when low-temperature water flows into the second space 11bb from the upper space 11a, the low-temperature water is mixed with the high-temperature water in the second space 11bb to generate water of an average temperature, that is, hot water. , since low-temperature water continuously flows into the second space 11bb, the generated hot water flows into the first space 11ba through the overflow pipe 70 .

At this time, the mixing ratio of the low-temperature water and the high-temperature water is changed according to the size ratio of the first space portion 11ba and the second space portion 11bb, and thus the temperature of the hot water is determined. 2 By designing the size of the space portion 11bb according to the purpose, a desired temperature of hot water can be set.

When water continuously flows into the first space 11ba and the water level rises, the float 51 rises and pressurizes the opening/closing unit 52 with buoyancy to block the through hole 21 while stopping the water inflow.

If heating continues in the second space 11bb in this state, steam is generated, and the generated steam flows into the first space 11ba through the overflow pipe 90 .

When the pressure of the first space 11ba increases due to steam inflow, the tube-side check valve 71 is closed, the outlet-side check valve 14 is opened, and the hot water filled in the first space 11ba is discharged through the outlet ( 13) through the heat exchanger (40).

The water discharged to the heat exchanger 40 undergoes heat exchange while passing through the heat exchanger 40 , and is introduced into the upper space 11a through the inlet 12 .

By repeating this process, the water cycle continues.

On the other hand, it is preferable that the opening/closing unit is formed to be smaller than the specific gravity of the water so that the float can rise by itself when the opening/closing unit cannot be lifted because the float cannot rise vertically.

Although the present invention has been described with reference to the above-mentioned preferred embodiments, various modifications and variations are possible without departing from the spirit and scope of the invention. Accordingly, it is intended that the appended claims cover such modifications and variations as fall within the scope of the present invention.
