Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a water circuit structure for an integrated water purifier and heat purifier. Background Technology

[0002] Integrated water purifiers and heaters, providing both room temperature and hot water, are gaining popularity and becoming an indispensable household appliance. Common integrated water purifiers on the market include a filter and a heating tank. Their working principle involves the filter directly outputting purified water from the tap water source, or heating the water in the heating tank before outputting it, thus providing either room temperature or hot water when connected to a tap.

[0003] Integrated water purifiers and heaters typically have a water level detection device inside the heating tank. This device limits the maximum water level in the tank. During water replenishment, when the device detects a high water level, it provides feedback, causing the system to stop replenishing the tank. The detection elements (such as floats or electrodes) of the water level detection device are usually located inside the heating tank. Due to limitations in the installation space of the detection elements and the detection method, the maximum water level is generally lower than the top surface of the heating tank. In other words, when water is replenished to the high water level, the tank is not completely full, and a significant amount of air accumulates in the unfilled space at the top of the tank, increasing the risk of bacterial growth. In addition, most integrated water purifiers and heaters use a pump to draw water from the heating tank to the faucet. This method has some problems. For example, the pump is the largest component in the integrated water purifier and heater, taking up most of the installation space. This limitation hinders the development of integrated water purifiers towards thinner and smaller designs. Moreover, the vibration generated by the pump during operation is not conducive to noise reduction in integrated water purifiers and heaters. Utility Model Content

[0004] This application provides a water circuit structure for an integrated water purifier and heater to improve the technical problems of existing integrated water purifiers, such as the easy growth of bacteria when the heating tank is not full, and the large space occupied and high vibration and noise of the water pump used to draw water from the heating tank.

[0005] The technical solution adopted in this application is as follows:

[0006] A water circuit structure for an integrated water purifier and heater includes a filtration unit and a heating tank. The filtration unit includes a filter element and a booster pump for pressurizing water into the filter element. The heating tank has a water inlet and a hot water outlet. The filter element is connected to the water inlet through a heating water inlet pipe. The filter element can fill the heating tank to full water under the pressure of the booster pump, and can continue to add water to the full heating tank to push the hot water in the heating tank out from the hot water outlet.

[0007] In this technical solution, the purified water filtered by the filter element can enter the heating tank through the heating water supply pipeline, allowing the heating tank to heat the water. The filter element, under the pressure of the booster pump, can fill the heating tank to full capacity. When the heating tank is full, the booster pump continues to supply purified water produced by the filter element, creating a water outlet state where room temperature water enters through the inlet and hot water is ejected from the outlet. The ejected hot water can be delivered to the faucet of the integrated water purifier and heater for user use, while the room temperature water entering the heating tank compensates for the loss of hot water, ensuring the heating tank remains full at all times. Therefore, in this solution, the method of replenishing water to the heating tank through a booster pump and filter element and then pushing the hot water out has several advantages. First, compared to the existing method of pumping water from the heating tank, it saves the need for a dedicated water pump, thus saving installation space reserved for such a pump in the integrated water purifier and heater unit. This contributes to the unit's slimmer and smaller design, as well as vibration reduction and noise reduction. Second, as most of the hot water in the heating tank is gradually discharged through the hot water outlet under the action of pushing out room temperature water, the water in the heating tank gradually cools down, slowly turning from hot water to warm water. This ensures that the initial output of the water outlet is hot water, followed by warm water, guaranteeing a large supply of both hot and warm water at temperatures above room temperature, thus improving the user experience. Third, because the heating tank is always kept full of water, it effectively prevents external air from entering and accumulating inside the tank, thereby reducing bacterial growth.

[0008] The water circuit structure of the integrated water purifier and heat pump also includes a pure water tank. The filter element replenishes water to the pure water tank through a room temperature water supply pipeline. The pure water tank is connected to the room temperature water outlet of the integrated water purifier and heat pump through a room temperature water supply pipeline. A water pump is provided on the room temperature water supply pipeline. The water pump and the booster pump can operate simultaneously so that the pure water tank and the heat pump can discharge water together.

[0009] In this technical solution, the pure water filtered by the filter element can enter the pure water tank for storage through the ambient temperature water replenishment pipeline. The pure water tank can directly discharge water to the ambient temperature water outlet of the integrated water purifier and heat pump through the ambient temperature water supply pipeline. Compared with the water supply method where the filter element produces water while simultaneously delivering the produced water to the ambient temperature water outlet, the water pre-stored in the pure water tank can provide a large flow rate to the ambient temperature water outlet, increasing the water output per unit time. In addition, when the water pump and the booster pump work together, the process of the filter element replenishing water to the heating tank and the process of the pure water tank discharging water to the ambient temperature water outlet occur simultaneously. Thus, while water is being discharged from the ambient temperature water outlet, hot water in the heating tank is also being pushed out, achieving simultaneous discharge of ambient temperature water and hot water. This allows for the mixing of ambient temperature water and hot water in the faucet of the integrated water purifier and heat pump, achieving a large flow rate of warm water output.

[0010] The ambient temperature water supply pipeline is equipped with a water tank supply valve, and the pure water tank is equipped with a water level detection device, which includes a low water level detection float and a high water level detection float that is higher than the low water level detection float.

[0011] In this technical solution, the water tank replenishment valve controls the opening and closing of the room temperature water replenishment pipeline, the water level detection device detects the water level in the pure water tank, the low water level detection float detects the low water level, and the high water level detection float detects the high water level. When the low water level in the pure water tank is detected, the system can control the filter element to produce water and replenish the pure water tank in a timely manner until the high water level detection float detects the high water level.

[0012] The heating water supply pipeline is equipped with a hot water tank supply valve, and the hot water outlet is connected to the hot water discharge port of the integrated water purifier and heat pump.

[0013] In this technical solution, the hot water supply valve controls the opening and closing of the heating water supply pipeline. When the hot water supply valve is opened, the hot water pushed out from the hot water outlet can flow to the hot water discharge outlet.

[0014] The hot water outlet is connected to the inlet of the reversing valve, the first outlet of the reversing valve is connected to the hot water outlet of the integrated water purifier and heat pump through the hot water discharge pipe, and the second outlet of the reversing valve is connected to the wastewater discharge pipe of the filter element through the exhaust pipe.

[0015] In this technical solution, when the first outlet valve is opened, the filter element can replenish water to the hot tank and push the hot water out. The hot water flows to the hot water discharge port through the reversing valve. When the second outlet valve is opened, the filter element cannot replenish water to the hot tank. The steam generated in the hot tank due to heating can flow to the wastewater discharge pipeline through the reversing valve.

[0016] The hot tank is equipped with a heating element for heating, which can heat the tank during the process of the filter element replenishing water into the hot tank.

[0017] In this technical solution, during the process of the filter element replenishing water to the hot water tank and pushing out hot water, the heating element can be controlled to be in a heating state continuously, forming a working mode of heating while water is being discharged, ensuring that warm water is always discharged throughout the entire water discharge process.

[0018] Both the water inlet and the hot water outlet are located at the top of the hot water tank. The water inlet is connected to a water guide pipe, which is used to guide the water entering through the water inlet to the bottom of the hot water tank.

[0019] In this technical solution, when the filter element replenishes water to the hot tank, room temperature water enters from the water inlet at the top of the hot tank and flows to the bottom of the hot tank under the guidance of the water pipe. The room temperature water pushes the hot water out from the hot water outlet from the bottom of the hot tank. The room temperature water at the bottom is far from the hot water outlet, and the water discharged from the hot water outlet is as hot as possible.

[0020] The water inlet is located at the bottom of the hot water tank, and the hot water outlet is located at the top of the hot water tank.

[0021] In this technical solution, when the filter element replenishes water to the hot tank, room temperature water enters from the water inlet at the bottom of the hot tank, and hot water is pushed out from the hot water outlet at the top of the hot tank. Since the density of room temperature water is greater than that of hot water, the hot water mainly concentrates in the upper part of the hot tank, while the replenished room temperature water mainly concentrates in the lower part of the hot tank. Therefore, it helps to slow down the mixing of hot water and room temperature water and ensures that the water discharged from the hot water outlet during the process of replenishing water to the hot tank is as much hot water as possible.

[0022] The hot tank is equipped with a water-blocking part. The projection of the water-blocking part on the horizontal plane covers the projection of the water inlet on the horizontal plane, so that the water-blocking part stops the water flow entering from the water inlet and changes the flow direction of the water.

[0023] In this technical solution, the room temperature water added to the hot tank by the water baffle is blocked, so that the room temperature water changes its flow direction. The room temperature water turns from its original vertical upward direction to avoid directly rushing the hot water at the top, thereby slowing down the mixing of room temperature water and hot water, so as to ensure that the water pushed out from the hot water outlet is at a high temperature as much as possible.

[0024] The filter element is connected to the ambient temperature water outlet of the integrated air purifier and heat dissipation unit via an ambient temperature water discharge pipe, and an ambient temperature water outlet valve is provided on the ambient temperature water discharge pipe.

[0025] In this technical solution, the filter element can directly discharge water to the ambient temperature water outlet through the ambient temperature water discharge pipe. When this solution is combined with the aforementioned solution where the pure water tank is connected to the ambient temperature water outlet of the integrated water purifier and heater through the ambient temperature water supply pipe, the booster pump can be controlled to run while the water supply pump and the water outlet pump are running together. At this time, while ambient temperature water is discharged from the ambient temperature water outlet and hot water in the hot water tank is pushed out, the filter element also directly discharges ambient temperature water to the ambient temperature water outlet. Water is discharged from all three water lines at the same time. When the water from the three water lines mixes in the faucet of the integrated water purifier and heater, a super-large flow of warm water is achieved, which greatly increases the water flow rate. Moreover, the water discharged from the pure water tank and the water discharged from the hot water tank can dilute the high TDS value water discharged from the filter element, thereby reducing the TDS value of the discharged water.

[0026] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: the pure water filtered by the filter element can enter the hot water tank through the heating water supply pipeline, so that the hot water tank heats the water, and the filter element can replenish the hot water tank to a full state under the pressure of the booster pump. When the hot water tank is full, the pure water produced by the filter element continues to be replenished into the hot water tank through the booster pump, so that the hot water tank forms a state where room temperature water enters through the water supply inlet and hot water is pushed out through the hot water outlet. The pushed-out hot water can be delivered to the faucet of the integrated water purifier and heat pump for users to use, while the room temperature water entering the hot water tank makes up for the gap left by the hot water discharge, so that the hot water tank is always kept full. Therefore, in this solution, the method of replenishing water to the heating tank through a booster pump and filter element and then pushing the hot water out has several advantages. First, compared to the existing method of pumping water from the heating tank, it saves the need for a dedicated water pump, thus saving installation space reserved for such a pump in the integrated water purifier and heater unit. This contributes to the unit's slimmer and smaller design, as well as vibration reduction and noise reduction. Second, as most of the hot water in the heating tank is gradually discharged through the hot water outlet under the action of pushing out room temperature water, the water in the heating tank gradually cools down, slowly turning from hot water to warm water. This ensures that the initial output of the water outlet is hot water, followed by warm water, guaranteeing a large supply of both hot and warm water at temperatures above room temperature, thus improving the user experience. Third, because the heating tank is always kept full of water, it effectively prevents external air from entering and accumulating inside the tank, thereby reducing bacterial growth.

[0035] In the embodiments of this application, a water circuit structure for an integrated water purifier and heat pump is provided, specifically providing... Figure 1 The embodiments of the water circuit structure of the integrated water purifier and heat pump shown are illustrated below for ease of explanation and understanding. All descriptions provided in this application are based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is merely a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solutions provided in this application.

[0036] Reference Figure 1As shown, the water circuit structure of the integrated water purifier and heater provided in this application includes a filtration unit and a heating tank 10. The filtration unit includes a filter element 11 and a booster pump 12 for pressurizing water into the filter element 11. The heating tank 10 is provided with a water inlet 101 and a hot water outlet 102. The filter element 11 is connected to the water inlet 101 through a heating water inlet pipe 13. The filter element 11 can fill the heating tank 10 with water to a full state under the pressurization action of the booster pump 12, and can continue to fill the full heating tank 10 with water, thereby pushing the hot water in the heating tank 10 out from the hot water outlet 102.

[0037] In a preferred embodiment, the filter element 11 can be a reverse osmosis filter element or a composite filter element composed of a reverse osmosis membrane and other filter media to improve the filtration effect. The inlet end of the booster pump 12 is connected to a raw water inlet valve 14. The filter element 11 can also discharge wastewater through a wastewater discharge pipe 15, which is equipped with a wastewater valve 16. When the raw water inlet valve 14 is open, tap water can enter the water circuit structure of the integrated water purifier and heat pump. Under the pressure of the booster pump 12, it enters the filter element 11 and is filtered into pure water. When the wastewater valve 16 is open, wastewater can be discharged. The pure water produced by the filter element 11 can enter the heating tank 10 for storage through the heating water supply pipe 13. Then, the heating tank 10 heats the water for later use. A temperature detection element can be installed at the bottom of the heating tank 10 to provide feedback on the heating temperature inside the tank.

[0038] In this technical solution, the pure water filtered by the filter element 11 can enter the heating tank 10 through the heating water supply pipe 13, so that the heating tank 10 heats the water. Under the pressure of the booster pump 12, the filter element 11 can fill the heating tank 10 with water. When the heating tank 10 is full, the pure water produced by the filter element 11 continues to be added to the heating tank 10 through the booster pump 12, so that the heating tank 10 forms a state where room temperature water enters through the water supply inlet 101 and hot water is pushed out through the hot water outlet 102. The pushed-out hot water can be delivered to the faucet of the water purifier and heat pump for the user to use, while the room temperature water entering the heating tank 10 makes up for the gap left by the hot water discharge, so that the heating tank 10 is always full of water. Therefore, in this solution, the method of replenishing water to the heating tank 10 and ejecting hot water through the booster pump 12 and filter element 11 has several advantages. First, compared to the existing method of drawing water from the heating tank using a pump, it saves the need for a dedicated water pump, thus saving the installation space reserved for such a pump in the integrated water purifier and heater, which helps to make the integrated water purifier and heater thinner, smaller, and reduce vibration and noise. Second, as most of the hot water in the heating tank 10 is gradually discharged from the hot water outlet 102 under the ejection action of room temperature water, the water in the heating tank 10 gradually cools down, slowly turning from hot water to warm water. This ensures that the heating tank 10 outputs hot water at the beginning and warm water at the end, guaranteeing a large supply of hot and warm water at temperatures higher than room temperature, thus improving the user experience. Third, since the heating tank 10 is always kept full of water, it effectively prevents external air from entering and accumulating inside the heating tank 10, thereby reducing bacterial growth.

[0039] In a preferred embodiment of this application, the water circuit structure of the integrated water purifier and heat pump further includes a pure water tank 17. The filter element 11 replenishes water to the pure water tank 17 through a room temperature water supply pipe 18. The pure water tank 17 is connected to the room temperature water outlet 20 of the integrated water purifier and heat pump through a room temperature water supply pipe 19. A water outlet pump 21 is provided on the room temperature water supply pipe 19. The water outlet pump 21 and the booster pump 12 can operate simultaneously to make the pure water tank 17 and the heat tank 10 discharge water together. In this technical solution, the pure water filtered by the filter element 11 can be replenished into the heating tank 10 through the heating water supply pipe 13, and can also be stored in the pure water tank 17 through the room temperature water supply pipe 18. The pure water tank 17 can directly discharge water to the room temperature water outlet 20 of the integrated water purifier and heat pump through the room temperature water supply pipe 19. Compared with the water supply method of the filter element 11 producing water while simultaneously delivering the produced water to the room temperature water outlet 20, the water pre-stored in the pure water tank 17 can be supplied to the room temperature water outlet 20 in a large flow rate, increasing the water output per unit time. In addition, when the water pump 21 and the booster pump 12 work together, the process of the filter element 11 replenishing water into the heating tank 10 and the process of the pure water tank 17 discharging water to the room temperature water outlet 20 are carried out simultaneously. Thus, while water is being discharged from the room temperature water outlet 20, the hot water in the heating tank 10 is also pushed out, realizing the simultaneous discharge of room temperature water and hot water. This allows for the mixing of room temperature water and hot water in the faucet, achieving a large flow rate of warm water output. In addition, by adjusting the duty cycles of the outlet pump 21 and the booster pump 12 respectively, the flow rate of room temperature water from the pure water tank 17 to the room temperature water outlet 20 and the flow rate of hot water from the hot tank 10 can be adjusted, thereby mixing water of different temperatures as required.

[0040] Furthermore, the ambient temperature water supply pipeline 18 is equipped with a water tank supply valve 22, and the pure water tank 17 is equipped with a water level detection device 23. The water level detection device 23 includes a low water level detection float and a high water level detection float that is higher than the low water level detection float. In this technical solution, the water tank supply valve 22 controls the opening and closing of the ambient temperature water supply pipeline 18, and the water level detection device 23 detects the water level of the pure water tank 17. The low water level detection float detects the low water level, and the high water level detection float detects the high water level. When a low water level is detected in the pure water tank 17, the system can control the filter element 11 to produce water and supply water to the pure water tank 17 in a timely manner until the high water level detection float detects the high water level.

[0041] In a preferred embodiment of this application, the heating water supply pipeline 13 is equipped with a hot water tank supply valve 24, and the hot water outlet 102 is connected to the hot water discharge port 25 of the integrated water purifier and heater. In this technical solution, the hot water tank supply valve 24 controls the opening and closing of the heating water supply pipeline 13. When the hot water tank supply valve 24 is open, the hot water pushed out from the hot water outlet 102 can flow to the hot water discharge port 25. Specifically, both the ambient temperature water discharge port 20 and the hot water discharge port 25 can be connected to a faucet, so that the ambient temperature water discharged from the ambient temperature water discharge port 20 and the hot water discharged from the hot water discharge port 25 are mixed in the faucet before being discharged.

[0042] Furthermore, the hot water outlet 102 is connected to the inlet 261 of the reversing valve 26, the first outlet 262 of the reversing valve 26 is connected to the hot water outlet 25 of the integrated water purifier and heat pump unit through the hot water discharge pipe, and the second outlet 263 of the reversing valve 26 is connected to the wastewater discharge pipe 15 of the filter element 11 through the exhaust pipe 27. In this technical solution, when the first outlet 262 is open, the filter element 11 can replenish water to the heating tank 10 and push out the hot water, which flows through the reversing valve 26 to the hot water outlet 25 for discharge; when the second outlet 263 is open, the filter element 11 cannot replenish water to the heating tank 10, and the steam generated in the heating tank 10 due to heating can flow through the reversing valve 26 to the wastewater discharge pipe 15 for discharge. Furthermore, those skilled in the art will understand that in commercially available integrated water purifiers, the heating tank is typically connected to a faucet via an exhaust pipe, allowing steam generated inside the heating tank to be discharged through the faucet. However, when a user fills their water tank, their face is usually positioned directly in front of and above the faucet, making it easy for steam to directly hit the user's face, causing burns and posing a safety hazard. Therefore, in this solution, the steam generated during the heating process of the heating tank 10 can be discharged through the reversing valve 26 into the wastewater discharge pipe 15. The wastewater discharge pipe 15 is typically connected to a municipal sewer or wastewater collection container, thus avoiding the safety hazard caused by steam being discharged through the faucet. Preferably, a check valve 20 can be installed on the exhaust pipe 27 to prevent wastewater from flowing through the exhaust pipe 27 towards the reversing valve 26 when the filter element 11 discharges wastewater.

[0043] In a preferred embodiment of this application, the heating tank 10 is equipped with a heating element 103 for heating. The heating element 103 can heat the water as the filter element 11 replenishes the water into the heating tank 10. In this technical solution, during the process of the filter element 11 replenishing water into the heating tank 10 and pushing out hot water, the heating element 103 can be controlled to be in a heating state continuously, forming a working mode of heating while water is being discharged, ensuring that warm water is always discharged throughout the entire water discharge process. Specifically, under the pressure boosting action of the booster pump 12, when the filter element 11 replenishes pure water into the heating tank 10, the heating element 103 in the heating tank 10 heats up simultaneously. Although the water temperature gradually decreases as the water discharge from the heating tank 10 increases, the heating element 103 compensates for the temperature drop, making the cooling and heating processes occur simultaneously, thus extending the time for warm water to be discharged.

[0044] In a preferred embodiment of this application, the water inlet 101 and the hot water outlet 102 are both located at the top of the hot water tank 10. The water inlet 101 is connected to a water guide pipe 104, which is used to guide the water entering through the water inlet 101 to the bottom of the hot water tank 10. In this technical solution, when the filter element 11 replenishes water to the hot tank 10, room temperature water enters from the water inlet 101 at the top of the hot tank 10 and flows to the bottom of the hot tank 10 under the guidance of the water guide pipe 104. The room temperature water pushes the hot water out from the hot water outlet 102 from the bottom of the hot tank 10. The room temperature water at the bottom is far from the hot water outlet 102, so the water discharged from the hot water outlet 102 is as much hot water as possible. Moreover, since the density of room temperature water is greater than that of hot water, the hot water is mainly concentrated in the upper part of the hot tank 10, while the replenished room temperature water is mainly concentrated in the lower part of the hot tank 10. This helps to slow down the mixing of hot water and room temperature water, and further ensures that the water discharged from the hot water outlet 102 is as much hot water as possible.

[0045] In other embodiments not shown in the accompanying drawings, the water inlet can be located at the bottom of the hot water tank, and the hot water outlet at the top of the hot water tank. In this technical solution, when the filter element replenishes water to the hot water tank, room temperature water enters from the water inlet at the bottom of the hot water tank, and hot water is pushed out from the hot water outlet at the top of the hot water tank. Similarly, because the density of room temperature water is greater than that of hot water, the hot water mainly concentrates in the upper part of the hot water tank, while the replenished room temperature water mainly concentrates in the lower part of the hot water tank. This ensures that during the process of replenishing water to the hot water tank, the water discharged from the hot water outlet is as much as possible hot water at a higher temperature. Furthermore, a water-blocking part can be provided inside the hot water tank. The projection of the water-blocking part on the horizontal plane covers the projection of the water inlet on the horizontal plane, causing the water-blocking part to stop the water flow entering through the water inlet and change the direction of water flow. In this technical solution, the room temperature water added to the hot tank by the water baffle is blocked, so that the room temperature water changes its flow direction. The room temperature water turns from its original vertical upward direction to avoid directly rushing the hot water at the top, thereby slowing down the mixing of room temperature water and hot water, so as to ensure that the water pushed out from the hot water outlet is at a high temperature as much as possible.

[0046] In a preferred embodiment of this application, the filter element 11 is connected to the ambient temperature water outlet 20 of the integrated water purifier and heater via an ambient temperature water outlet pipe 28, and an ambient temperature water outlet valve 29 is provided on the ambient temperature water outlet pipe 28. When the ambient temperature water outlet valve 29 is open, the filter element 11 can directly discharge water into the ambient temperature water outlet 20. When the ambient temperature water outlet valve 29 is closed, the filter element 11 can no longer discharge water into the ambient temperature water outlet 20. While filter element 11 discharges room temperature water into room temperature water outlet 20, at least one of booster pump 12 and outlet pump 21 can be controlled to operate, thus forming three water supply states: First, while filter element 11 discharges room temperature water into room temperature water outlet 20, outlet pump 21 also draws room temperature water from pure water tank 17. Pure water tank 17 then supplies room temperature water to room temperature water outlet 20 through room temperature water supply pipeline 19, thereby achieving a large flow rate of room temperature water output. Furthermore, the water discharged from pure water tank 17 can dilute the high TDS value water discharged from filter element 11, thereby reducing the TDS value of the discharged water. Second, while filter element 11 discharges room temperature water into room temperature water outlet 20, under the boosting action of booster pump 12, filter element 11 replenishes pure water into the outlet. In the hot water tank 10, hot water is pushed out of the hot water tank 10 and discharged through the hot water outlet 25. It is possible to control the mixing of the room temperature water discharged from the room temperature water outlet 20 and the hot water discharged from the hot water outlet 25 to produce warm water. The third method is that while the filter element 11 discharges room temperature water to the room temperature water outlet 20, the water pump 21 also takes room temperature water from the pure water tank 17, and the booster pump 12 also pressurizes the filter element 11 to replenish water to the hot water tank 10. The room temperature water from the filter element 11 and the pure water tank 17 is discharged through the room temperature water outlet 20, and the hot water from the hot water tank 10 is discharged through the hot water outlet 25. It is possible to control the mixing of the room temperature water discharged from the room temperature water outlet 20 and the hot water discharged from the hot water outlet 25 to produce warm water. It is a three-way water mixing to achieve ultra-high flow rate of warm water output.
