The present invention relates to a water body recirculation system, in particular to a water heater co-distribution, forcing a water body to circulate on a closed return path including a water heater, and continuously heating the initial water body with insufficient temperature until it is hot enough to avoid any loss and waste of the initial water body. A water body recirculation system.

Usually at home, use hot water to bathe, wash your face, wash clothes, wash dishes, etc. When you need hot water for housework, when the hot water tap is just opened, the water that flows out is usually cold and cold. After the time, the water that has flowed out will start to warm up. After a while, the water that flows out will become hot enough to start bathing, washing clothes, doing housework, etc., while waiting for cold water to turn hot water. In the middle of these warm or cold water, usually everyone inadvertently let it drain.

In recent years, due to the intensification of global warming, water resources, especially fresh water, have begun to be scarce.

Fig. 1 is a schematic view showing the switching device of the present invention in an open state; the water reflow heating system 300 of the present invention is preferably applied to a water heater 500, which is preferably a domestic natural gas water heater and a household gas. The water heater, the household electric water heater, the industrial water heater, the water heater, or the electric water heater, the water heater 500 has a heater inlet 510 and a heater outlet 520. Usually, the cold water enters the water heater 500 from the heater inlet 510, and passes through the water heater. After heating 500, it becomes hot water and is discharged from the heater outlet 520. In the present embodiment, the water heater is preferably a domestic water heater.

In the first embodiment of the present invention, the water body reflow heating system 300 mainly includes a main device such as a switching valve device 100, a control module 200, an operation panel 210, and a display panel 220. The switching valve device 100 further includes a cold pipe (first pipe body). 10. Heat pipe (second pipe body) 20, cold pipe inlet (first inlet) 11, cold pipe outlet (first outlet) 12, heat pipe inlet (second inlet) 21, heat pipe outlet (second outlet) 22, cold Pipe valve (first valve) 13, heat pipe valve (second valve) 23, communication device 30, temperature detector 40, pressure detector 50, drive blade 60 and the like, cold pipe outlet 12 and water heater 500 The heater inlet 510 is coupled to communicate with the heater outlet 520 of the water heater 500. The cold tube inlet 11 is coupled to the original water supply pipe connected to the water heater 500, and the heat pipe outlet 22 is coupled. Connected to the hot water tap, the communication device 30 in the present embodiment is preferably a communication tube.

The drive blade 60 is disposed within the communication device 30 and is subjected to a power motor (not shown) The drive can be rotated at different rotational speeds to drive the water body in the communication device 30. The drive blade 60 is preferably a propeller blade to drive the water body in the communication device 30 in a submerged manner, or the drive blade 60 is preferably a waterwheel type. The blade drives the water body in the communication device 30 in a semi-immersed manner. The communication device 30 is shaped to include a chamber or a protrusion for accommodating the drive blade 60. The temperature detector 40 monitors the temperature change of the water body. The pressure detector 50 monitors the pressure change of the water body. The temperature detector 40 and the pressure detector 50 are preferably disposed near the wall of the heat pipe 20 at the heat pipe inlet 21 to detect the water heater at the heater outlet 520. The water temperature and water pressure are used as the basis for controlling the cold pipe valve 13 and the heat pipe valve 23. The heat pipe 20 near the heat pipe inlet 21 can also be provided with other types of detectors, such as a flow rate detector ( Not shown), a flow detector (not shown), etc., to detect the flow condition parameters of the water heater at the heater outlet 520 as a basis for regulating the cold tube valve 13 and the heat pipe valve 23.

The cold pipe valve 13 can be in the return position CC (completely blocking the flow of the water body in the cold pipe 10, or completely opening the communication between the cold pipe 10 and the communication device 30), the open position AC (the flow of the completely open water body in the cold pipe 10) ), or moving back and forth between the reflow position CC and the open position AC (obtaining different valve opening degrees), the heat pipe valve 23 can also be in the reflow position CH (completely blocking the flow of the water body in the heat pipe 20, or completely opening the heat pipe 20 with The communication device 30 is connected, the open position AH (the flow of the completely open water body in the heat pipe 20), or the return position CH and the open position AH (to obtain different valve opening degrees) are moved back and forth, through different valve opening combinations, Different functions can be obtained. The position or state switching of the cold pipe valve 13 and the heat pipe valve 23 is synchronously controlled by the power motor of the driving blade 60, or the position or state of the cold pipe valve 13 and the heat pipe valve 23 are switched, and can also be respectively transmitted through Two additional dedicated motors (not shown) are completed.

In the open state, the cold pipe valve 13 is in the open position AC, and the heat pipe valve 23 Also in the open position AH, in this state, cold water having a relatively low temperature flows from the cold pipe inlet 11 into the cold pipe 10, enters the switching valve device 100, flows out from the cold pipe outlet 12, and then enters from the heater inlet 510. The water heater 500, after flowing and heating the cold water in the water heater 500, flows out from the heater outlet 520 of the water heater 500, then flows into the heat pipe 20 from the heat pipe inlet 21, and then flows out from the heat pipe outlet 22 to discharge the switching valve device 100. A small portion of the cold water flowing into the cold pipe 10 may enter the communication device 30, but does not affect the flow of cold water into the water heater 500 via the cold pipe 10.

When the switching valve device 100 is in the open state, the water flow flows in the switching valve device 100, and unlike the flow process in which the normal cold water enters the water body heater 500 and is discharged after being heated by the water body heater 500, the switching valve device 100 does not change the flow of the water flow. In the process, the water flows along the open path 70 of the cold pipe inlet 11, the cold pipe 10, the heater inlet 510, the water heater 500, the heater outlet 520, the heat pipe inlet 21, the heat pipe 20, and the heat pipe outlet 22.

However, when the water heater 500 is just started, until the initial water body can be stably heated to the required temperature D, it usually takes a period of time T, and it is necessary to wait for the temperature of the internal ignition system, the combustion chamber, and the heat exchanger and the like of the water heater. Rising, to gradually heat the initial water body from a low temperature state to a relatively high demand temperature D, and to maintain the water body temperature stably at the demand temperature D, the length of the time T, depending on the performance of the water heater 500 And it is different.

However, during this time T, the faucet continues to flow out of these colder water, warm water, or water that does not reach the required temperature D. Usually, because the temperature of these initial water bodies is too cold, users generally do not actually use the water. However, it will not be stored, most of them are randomly discharged, which actually causes waste of water resources. However, the present invention proposes that the switching valve device 100 can form a closed return flow path together with the water heater 500, and is forced to have no The initial water body reaching the required temperature D is continuously circulated in the water heater 500, and is repeatedly heated to the required temperature D, such as This can effectively avoid the waste of water resources.

2 is a schematic diagram of the switching valve device in the reflow state; when the switching valve device 100 is in the reflow state, the driving blade 60 will start to rotate at this time, and the cold pipe valve 13 moves to the return position CC, and the heat pipe valve 23 also Moving to the return position CH, since the cold pipe valve 13 and the heat pipe valve 23 are both closed, a closed return path 80 is substantially formed between the cold pipe 10, the water heater 500, the heat pipe 20, and the communication device 30, and The water body is continuously circulated in the return path 80 formed by the cold pipe 10, the water heater 500, the heat pipe 20, and the communication device 30 under the driving of the driving blade 60. During the circulating flow, the water body continues to be subjected to the water heater 500. The heating is continued until the temperature detector 40 detects that the temperature of the water body is greater than or equal to the required temperature D, and then switches the switching valve device 100 to the open state.

Therefore, through the switching valve device 100, the cold water body that does not reach the required temperature D can be continuously circulated in the return path 80, and is continuously heated by the water body heater 500 until it is hot enough, and since the driving blade 60 can strongly recool the water. The circulation path 80 continuously circulates to ensure the operation of the water heater ignition system, and continuously heats the cold water body until the water temperature reaches the demand temperature D, and then returns the switching valve device 100 to the open state.

The switching between the open state and the reflow state of the entire switching valve device 100 can be automatically completed by the control module 200 in conjunction with the temperature detector 40, the pressure detector 50, etc., and the user can access the switching valve device through the operation panel 210. 100 performs related settings, and switches information such as the operating conditions of the valve device 100, the water temperature, and the like to the user through the display panel 220.

Taking a family bathroom and a domestic water heater as an example, the water reflow heating system 300 of the present invention actually uses the situation that the water reflow heating system of the present invention is first assembled with the water heater pipeline, that is, the cold water inlet 11 and the original water supply of the water heater. Pipe connection, heat pipe outlet 22 is connected with the pipeline of the hot water tap of the bathroom, connects the cold pipe outlet 12 with the water inlet of the water heater, connects the heat pipe inlet 21 with the water outlet of the water heater, and the hot water tap can be mixed with hot water and hot water. Faucet, or pure water faucet.

At the beginning, the switching valve device 100 is in an open state, the user sets the required temperature D through the operation panel 210, and reads information such as temperature and water pressure through the display panel 220 to confirm that the system is normal, and then the user opens the faucet, and the water body begins to follow. The open path enters the switching valve device 100 and the water heater, activates the ignition system of the water heater, and the water heater begins to heat the water body. At this time, the temperature detector 40 and the pressure detector 50 continuously monitor the water temperature and the water pressure.

If the water temperature W at the heat pipe inlet 21 (close to the water outlet temperature of the water heater) is much smaller than the demand temperature D, and the water pressure value is lowered or the flow rate is increased, the switching valve device 100 is switched by the control of the control module 200. In the return state, the water body is left in the closed return path 80 including the water heater, and the driving of the driving blade 60 forces the water body to circulate in the return path, and is constantly heated by the water heater.

If the water temperature W at the heat pipe inlet 21 is still less than the demand temperature D, and the water pressure value is rebounded, the switching valve device 100 is continuously maintained in the reflow state by the control of the control module 200, and the driving blade 60 is continuously operated to make the water body The circulation is circulated in the return path to receive heating of the water heater.

If the water temperature W at the heat pipe inlet 21 is already close to the demand temperature D, the water pressure value may be ignored and the cold pipe valve 13 or the heat pipe valve in the switching valve device 100 may be partially opened or partially closed by the control demand of the control module 200. 23, or reduce the rotational speed of the driving blades in the communication device 30, at this time, new cold water from the cold pipe inlet 11 is added to the return path, and the water heater is heated to help shorten the heating time of the water body to an acceptable temperature.

If the water temperature W at the heat pipe inlet 21 has reached the demand temperature D, the water pressure value can be ignored, and the switching valve device 100 is switched to the open state by the control of the control module 200, and the rotation of the driving blade 60 is stopped. The water body naturally flows out of the hot water tap for the user to use.

As shown in FIGS. 1 and 2, in the second embodiment of the present invention, the water body reflow heating system 300 includes the components of the first embodiment, and further includes a first sheet disposed on the path of the heat pipe 20. To the valve 90, the extension pipe 91, and the second check valve 92, the first check valve 90 and the second check valve 92 are preferably disposed at the heat pipe valve 23 of the heat pipe 20 or at the return position CH.

When the switching valve device 100 is in the reflow state, although the water body in the closed return path 80 can continuously circulate in the return path 80, it is continuously heated by the water heater 500, but due to the reflow state, the heat pipe valve 23 In the return position CH, the water body in the heat pipe 20 is blocked by the heat pipe valve and cannot flow to the hot water tap, so the water body in the pipe is still from the heat pipe valve 23 to the small draft pipe 95 between the hot water taps. cold.

Therefore, the present invention further provides two one-way check valves of different check directions in the path of the heat pipe 20, that is, the first check valve 90 and the second check valve 92. The first check valve 90 preferably only allows the water body to pass from. The heat pipe 20 flows into the draft pipe 95 without allowing the water body to flow from the draft pipe 95 into the heat pipe 20. The second check valve 92 preferably only allows the water body to flow from the draft pipe 95 into the heat pipe 20 without allowing the water body to flow from the heat pipe 20 into the draft pipe 95, and then borrows Appropriate water pressure is applied in a suitable manner from a body of water from between the heater outlet 520 to the return position CH or between the heat pipe inlet 21 and the return position CH, for example by additionally providing a pressurizing motor (not shown) for recirculation. A part of the path 80 that does not reach the required temperature D of the micro hot water or the warm water can flow into the first check valve 90, substantially follows the flow path 81, flows into the draft tube 95 through the first check valve 90, and the warm water is in the draft tube 95. After convection, mixing with cold water or heating cold water, From the second check valve 92, the draft water pipe 95 flows back to the return path 80, and continues to receive heating of the water heater 500.

The extension pipe 91 can more efficiently bring the warm water flowing from the return path 80 through the first one-way valve 90 into the draft water pipe 95, and more effectively enter the position deeper into the draft water pipe 95 or even near the end of the draft water pipe 95, and then flow in. The warm water of the draft tube can produce a better mixing and heating effect with the cold water in the draft tube 95, and improve the overall heating effect on the water body in the draft tube.

Therefore, in the second embodiment of the present invention, the first check valve 90 and the second check valve 92 are disposed in the heat pipe 20, so that warm water can be branched from the return path 80 into the draft pipe 95 while heating the inside of the draft pipe 95. Cold water, this can more effectively reduce the waste of cold water that is not needed when used.

The creation water body recirculation system 300 can be simply assembled with a domestic water heater, and when the hot water tap is just opened, or when the water heater is just started, those initial water bodies that are not hot enough are repeatedly forced to circulate and continue inside the water heater. Heat until the water temperature is hot enough to naturally flow out of the hot water tap for the user to use.

Through the use of the created water body recirculation system, the initial water body can be heated continuously in the water heater to be hot enough to flow out from the faucet, which not only avoids the waste of the initial water body being discharged, effectively saves water resources, and does not require additional space. Water storage containers for storing these waters are very practical, simple, effective, and can be directly compatible and integrated with existing domestic water heater systems.
