Description

Hot water circulation system using steam pressure}

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

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

Such a hot water circulation device installs a hot water pipe in the mat and heats the mat by circulating hot water in the pipe, 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 circulating motor, electricity or a battery is required, noise is generated, and failure is frequent due to deterioration of the motor when used for a long time.

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

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

As shown in FIGS. 1A and 1B, the conventional hot water circulation device using vapor pressure includes a first tank 110 in which a receiving space 111 for receiving water is formed, and is installed under the first tank 110 and is In the second tank 120 in which the heating space 121 is formed, one end is in communication with the receiving space 111 and the other end is in communication with the heating space 121 so that the water received in the receiving space 111 is a heating space ( 121, an inlet pipe 130 for guiding to be received, a heating means 140 installed below the second tank 120 to heat the water contained in the second tank 120, and a second tank 120 at one end. ) Connected to the lower side of the water outlet pipe 150 connected to one end of the heat exchanger (H) and the other end disposed in the heating zone, and installed on one side of the inlet pipe 130 and the water outlet pipe 150, respectively. 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 recovery pipe 170 in communication with the receiving space 111 of the first tank (110).

In such a conventional hot water circulation device using vapor pressure, when water is introduced into the first tank 110 to a certain level, the check valve 160 on the inlet pipe 130 side is opened by gravity and pressure difference, and the inlet pipe 130 Water flows from the first tank 110 to the second tank 120 through ).

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

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

Thereafter, the hot water that has passed through the heat exchanger (H) is introduced into the first tank 110 through the recovery pipe 170 and the above operation is repeated.

However, in the conventional hot water circulating device using vapor pressure, when the pressure in the second tank 120 is lowered below a certain pressure, the check valve 160 on the inlet pipe 130 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.

Accordingly, there is a problem in that the second tank 120 is overheated and the steam flows into the heat exchanger (H) and condenses while passing through the heat exchanger, thereby obstructing the circulation of hot water.

In addition, since the conventional hot water circulating device 100 using vapor pressure has a structure in which hot water having a boiling point temperature is introduced into the heat exchanger, there is a problem that a heating device such as a hot water mat becomes too hot.

5 is a view showing a state in which water located in the upper space according to the first embodiment of the present invention flows into the lower space, and FIG. 6 is a state in which the opening and 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 being built.

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 FIGS. 5 to 8.

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

When water flows into the lower space 11b, the water level rises, and the float 51 rises together and reaches the opening/closing unit 52, the opening/closing unit 52 is pressurized toward the upper space 11a by buoyancy and the through hole ( 21) is shielded.

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

Thereafter, when the heating means 30 is operated and the lower space 11b is heated, the temperature of the water in the lower space 11b increases, and when the boiling point is reached, steam is generated and the pressure in the lower space 11b increases. .

When the pressure in the lower space 11b increases, the check valve 14 on the outlet side is opened so that 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 transferred to the heat exchanger 40 becomes the boiling point.

The hot water discharged to the heat exchanger 40 heat exchanges with the heating zone 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 with it. At this time, even if the float 51 descends and does not pressurize the opening/closing unit 52 upward, the pressure in the lower space 11b acts on the opening/closing unit 52, thereby shielding the through hole 21 by the opening/closing unit 52 The state is maintained, and hot water is continuously discharged to the heat exchanger 40.

Thereafter, when the float 51 continues to descend and 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 so that the through hole 21 is It is forcibly opened.

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

While water flows into the lower space 11b, the water in the lower space 11b is maintained below the boiling point, so that steam does not generate even if the water in the lower space 11b is continuously heated.

When water flows into the lower space 11b, the water level rises, and the float 51 rises together 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, 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 discharge port 13.

As this process is repeated, the water circulation continues.

9 is a view showing a state in which water flows into a lower space and vapor or air from the lower space is discharged to the upper space according to the second embodiment of the present invention, 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 through hole is shielded.

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 of the partition means 20 so that the upper end is in communication with the upper space 11a, is formed extending 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 vapor pressure according to the second embodiment of the present invention having such a configuration is as follows.

Prior to the description, initially, the inside of the tank 10 is empty, 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 It is assumed that the check valve 71 and the pipe body side are in an arbitrary state.

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

While water is introduced, the steam or air existing in the lower space 11b is discharged to the upper space 11a through the through hole 21 and condensed or discharged to the atmosphere.

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

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

Thereafter, when the heating means 30 is operated and the lower space 11b is heated, the temperature of the water in the lower space 11b increases, and when the boiling point is reached, steam is generated and the pressure in the lower space 11b increases. .

When the pressure in the lower space 11b increases, the pipe-side check valve 71 is closed, and the outlet-side check valve 14 is opened, so that the hot water generated in the lower space 11b is transferred to the heat exchanger through the discharge port 13. It is discharged to 40.

The hot water discharged to the heat exchanger 40 heat exchanges with the heating zone 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 with it. At this time, even if the float 51 descends and does not pressurize the opening/closing unit 52 upward, the pressure in the lower space 11b acts on the opening/closing unit 52, thereby shielding the through hole 21 by the opening/closing unit 52 The state is maintained, and hot water is continuously discharged to the heat exchanger 40.

Thereafter, when the float 51 continues to descend along 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 It is moved downward and the through hole 21 is forcibly opened.

Vapor from the lower space (11b) escapes through the open through hole (21), and is condensed while passing through the water of the upper space (11a) or discharged to the atmosphere.

In addition, when the steam in the lower space 11b is discharged and the pressure is lowered, the outlet-side check valve 14 is closed, and the pipe-side check valve 71 is opened so that the water in the upper space 11a flows through the pipe body 70. It is introduced into the lower space 11b through.

While water flows into the lower space 11b, the water in the lower space 11b is maintained below the boiling point, so that steam does not generate 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 to pressurize the opening/closing unit 52 upward with buoyancy, and the opening/closing unit 52 shields the through hole 21 The inflow is stopped.

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

As this process is repeated, the water circulation continues.

11 is a view showing a state in which water flows from the upper space to the lower 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. It is a drawing shown.

The basic configuration of Figs. 11 and 12 is the same as the embodiment of Figs. 9 and 10, but the spiral heating pipe 60 is added so that the water flowing from the upper space 11a passes through the heating pipe 60 and It flows into the space (11b), and the steam generated by heating the heating pipe (60) flows into the lower space (11b) to quickly generate steam, and the hot water discharged from the lower space (11b) is maintained below the boiling point. It is formed in a structure that can be made.

The heating pipe 60 of this embodiment has one end passing through one side of the tank 10 and connected to the tube body 70, and the other end passing through the other side of the tank 10 to be less than the maximum water level of water accommodated in the lower space. It is 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 vapor pressure according to the third embodiment of the present invention having such a configuration is as follows.

Initially, the inside of the tank 10 is empty 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 pipe 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.

While water is introduced, the steam or air existing in the lower space 11b is discharged to the upper space 11a through the through hole 21 and is condensed or discharged to the atmosphere.

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

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

Thereafter, 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 increases, the check valve 71 on the tube body is closed and the generated steam flows into the lower space 11b.

When steam continuously flows into the lower space 11b and the internal pressure increases, the check valve 14 on the outlet side 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 heat exchanges with the heating zone 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 with it. 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, thereby shielding the through hole 21 by the opening/closing unit 52 The state is maintained, and hot water is continuously discharged to the heat exchanger 40.

Thereafter, 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 moves downward. The through hole 21 is forcibly opened.

Vapor from 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, and the pipe body side check valve 71 is opened so that low temperature water from the upper space 11a is heated by the pipe 60 It is introduced into the lower space 11b through. 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 the low-temperature water flows in the upper space 11a, steam does not generate 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 to pressurize the opening/closing unit 52 upward with buoyancy, and the opening/closing unit 52 shields the through hole 21 The inflow is stopped.

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

As this process is repeated, the water circulation continues.

13 is a view showing a state in which water flows from the upper space to the second space according to the fourth embodiment of the present invention, and FIG. 14 is a state in which the opening and closing means according to the fourth embodiment of the present invention shields the through hole. Fig. 15 is a view showing a structure in which a discharge hole is formed at an upper end of an overflow pipe according to an embodiment of the present invention.

The basic configuration of FIGS. 13 and 14 is the same as the embodiment of FIGS. 9 to 10, but the additional compartment means 80 and the 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 used.

As shown in Figs. 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 part, so that the lower space 11b is formed as a first space. It is divided up and down into a part 11ba and a second space part 11bb.

The additional partition means 80 has a communication hole 81 formed on one side, an overflow pipe 90 extending above the communication hole 81, and the lower end of the tube body 70 is extended to the other side. It is coupled to communicate with the 2 space part (11bb)

When the water of the upper space 11a flows into the second space 11bb through the pipe body 70, the overflow pipe 90 is mixed with the hot water of the second space 11bb to form the first space ( 11ba)

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

On the other hand, in the overflow pipe 90 according to the present embodiment, the upper end is shown to be spaced apart from the bottom of the partition means 20, but 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 a state in close contact with the bottom surface of the partition means 20.

The operation of the hot water circulation device 1 using 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, 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 checks the outlet side check valve 14 and the tube side. 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 pipe body 70, and flows into the second space 11bb.

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

While water flows in, the vapor or air existing in the first and second spaces 11ba and 11bb escapes to the upper space 11a through the through hole 21 and is 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 the opening/closing unit 52 is pressed with buoyancy to close the through hole 21. do.

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

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

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

When steam continuously flows in and the pressure in the first space 11ba increases, the pipe-side check valve 71 is closed, and the outlet-side check valve 14 is opened, so that the water in the first space 11ba is opened. It is discharged to the heat exchanger 40 through the discharge port 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 is lowered and the float 51 descends with it. 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, thereby maintaining the shielded state of the through hole 21, and hot water is It is continuously discharged to the heat exchanger 40.

As described above, in the first circulation, since the first space 11ba is filled with unheated low-temperature water, the 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.

Thereafter, when the float 51 continues to descend and 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 so that the through hole 21 is It is forcibly opened.

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

When the steam is discharged and the pressure in the first space 11ba is lowered, the outlet-side check valve 14 is closed and the pipe-side check valve 71 is opened so that low-temperature water from the upper space 11a is lowered. ) Is introduced into the second space 11bb.

On the other hand, when liquid water changes to vapor, the volume is about 1000 times or more, so even if the vapor 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.

Therefore, when the low-temperature water flows from the upper space 11a to the second space 11bb, the low-temperature water and the high-temperature water in the second space 11bb are mixed to produce water of an average temperature, that is, hot water. , Since the low-temperature water continuously flows into the second space part 11bb, the generated hot water flows into the first space part 11ba through the overflow pipe 70.

At this time, the mixing ratio of the low-temperature water and the high-temperature water varies according to the size ratio of the first space part 11ba and the second space part 11bb. As a result, the temperature of hot water is determined. 2 It is possible to set the desired temperature of hot water by designing the size of the space part 11bb according to the purpose.

When the water level rises due to the continuous inflow of water into the first space 11ba, the float 51 rises and presses the opening/closing unit 52 with buoyancy to block the through hole 21 and the water inflow is stopped.

In this state, when heating is continued in the second space part 11bb, steam is generated, and the generated steam flows into the first space part 11ba through the overflow pipe 90.

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

Water discharged to the heat exchanger 40 undergoes heat exchange while passing through the heat exchanger 40, and flows into the upper space 11a through the inlet 12.

As this process is repeated, the water circulation continues.

Accordingly, the scope of the appended claims will include such modifications or variations that fall within the gist of the present invention.
