Description

Technical Field

[0001] This invention relates to the technical field of water supply pipelines, and in particular to a water circuit regulating component and a water supply system having the same. Background Technology

[0002] A gas appliance with zero cold water function has a water circuit regulating component in its pipeline. The water circuit regulating component includes a hot water pipe, a cold water pipe, and a connecting pipe between the hot water pipe and the cold water pipe. The connecting pipe contains a valve element. When the water temperature at the outlet of the gas appliance does not reach the predetermined requirement, the outlet of the pipeline (e.g., a shower head) is in a closed state, the valve element opens the connecting pipe, and the water in the hot water pipe flows back to the cold water pipe through the connecting pipe, and then returns to the hot water tank of the gas appliance through the cold water pipe for further heating.

[0003] When gas appliances use pressurization functions to supply hot water, the water in the pipes has a larger head after being pressurized by the water pump. Due to the resistance of the mixing pipe and shower head in the gas appliance pipes, the water in the hot water pipes will flow to the cold water pipes through the connecting pipes, resulting in cross-contamination.

[0004] In addition, in some areas where water pressure is high, when using cold water, the large pressure difference can cause valve components to open the connecting pipe, leading to the problem of gas appliances being accidentally started. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a water circuit regulating component that can prevent hot and cold water from flowing together, thereby saving energy.

[0006] The present invention also proposes a water supply system including the above-mentioned water circuit regulating components, which provides a better user experience and lower energy consumption.

[0007] A water circuit regulating assembly according to an embodiment of the present invention includes: a valve body having a hot water pipe, a cold water pipe, and a connecting pipe connecting the hot water pipe and the cold water pipe; a valve element disposed within the connecting pipe, wherein when the water pressure in the hot water pipe is greater than the water pressure in the cold water pipe, the valve element unidirectionally conducts the water circuit from the hot water pipe to the cold water pipe; and a temperature control element disposed within the connecting pipe, wherein when the water circuit from the hot water pipe to the cold water pipe is conducted and the water temperature in the connecting pipe reaches a predetermined value, the temperature control element cuts off the connecting pipe.

[0008] According to the water circuit regulating assembly of the present invention, the opening and closing of the connecting pipe is controlled by simultaneously setting a valve element and a temperature control element in the connecting pipe. In this way, even if the pressurization function is used in the water supply system, crossflow between the hot water channel and the cold water channel can be prevented, reducing the loss of hot water and energy consumption.

[0009] According to some embodiments of the present invention, the cold water pipe is provided with an installation interface opposite to the connecting pipe, and the installation interface is provided with an end cap for closing the installation interface. The valve element and the temperature control element are assembled into the connecting pipe through the installation interface, wherein the valve element is disposed adjacent to the hot water pipe.

[0010] In an optional embodiment, the end cap provides a first water channel and a second water channel that are interconnected, wherein the first water channel is connected to the connecting pipe and the second water channel is connected to the cold water pipe.

[0011] Further optionally, the end cap includes an insertion portion and a closing portion, the insertion portion being embedded in the outlet of the connecting pipe, the insertion portion forming the first waterway.

[0012] In one specific embodiment, the temperature control element includes at least a telescopic rod, which closes the inlet of the first water channel when the water temperature in the connecting pipe reaches a predetermined value.

[0013] Alternatively, when the water temperature in the connecting pipe reaches a predetermined value, the temperature control element applies a resisting force to the valve element, causing the valve element to close the inlet of the connecting pipe.

[0014] In one specific embodiment, the end cap includes an abutment portion and a pipe portion connected to each other, wherein the pipe portion forms a first water channel and a second water channel, the temperature control element is built into the end cap, the temperature control element includes at least a telescopic rod, one end of the telescopic rod is connected to the abutment portion, and the other end of the temperature control element is disposed opposite to the valve element.

[0015] In one specific embodiment, the valve body further includes a valve housing with both ends open. An abutment plate is provided at one end of the valve housing adjacent to the cold water pipe. The temperature control element is integrated on the valve element. The temperature control element includes at least a telescopic rod, one end of which is connected to the valve element, and the other end of which is disposed opposite to the abutment plate. When the water temperature in the connecting pipe reaches a predetermined value, the telescopic rod abuts against the abutment plate.

[0016] In some embodiments of the present invention, the valve element includes at least: a valve plug, a push rod, and an elastic element. The elastic element is sleeved on the push rod. When the water pressure in the hot water pipe is less than or equal to the water pressure in the cold water pipe, the elastic element applies a pushing force to the push rod to reset the valve plug, thereby closing the inlet of the connecting pipe.

[0017] Optionally, at least a portion of the telescopic rod is made of a phase change material, and the length of the telescopic rod extends or shortens as the water temperature inside the connecting pipe changes.

[0018] Alternatively, the telescopic rod may be provided with a return spring.

[0019] The water supply system according to the embodiments of the present invention includes the water circuit regulating component of the above embodiments. Since the water circuit regulating component according to the embodiments of the present invention can ensure that the water supply system has zero cold water and pressurization function, it avoids the crossflow of hot and cold water and saves energy. Therefore, the water supply system according to the embodiments of the present invention has a good user experience and low energy consumption.

[0020] In some embodiments of the invention, the water supply system includes: a heating device and a water outlet device, wherein a hot water path and a cold water path are provided between the heating device and the water outlet device, the hot water pipe is connected in series with the hot water path, and the cold water pipe is connected in series with the cold water path.

[0021] In an optional embodiment, the water supply system is provided with multiple water outlet devices, and the water path regulating component is set at the last water outlet device.

[0022] In some embodiments of the invention, the heating device includes a heating device and a water outlet device, with a hot water path and a cold water path provided between the heating device and the water outlet device, and a return water path connected between the hot water path and the cold water path, the hot water pipe being connected in series with the return water path, and the cold water pipe being connected in series with the cold water path.

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] The water supply system 1000 of this invention typically includes a heating device 200 and a water outlet device 300. The heating device 200 can be a gas water heater, a wall-hung boiler, a phase change water heater, or an electric water heater, etc., and the water outlet device 300 can be a shower head, a faucet, etc.

[0050] A hot water circuit 400 and a cold water circuit 500 are usually provided between the heating device 200 and the water outlet device 300. The hot water circuit 400 is connected to the hot water interface 202 of the heating device, and the cold water circuit 500 is connected to the cold water interface 201 of the heating device.

[0051] As is well known to those skilled in the art, a return water path 600 is typically provided between the hot water path 400 and the cold water path 500 to return residual cold water in the pipeline to the heating device 200 for heating, thereby enabling the water supply system 1000 to have a zero-cold-water function. However, when the water supply system 1000 adds a pressurization function or uses cold water alone, some hot water in the hot water path 400 can easily flow into the cold water path 500, resulting in a waste of hot water. Based on the above facts, the present invention provides a water path regulating component 100, which can both ensure that the water supply system 1000 obtains a zero-cold-water function and prevent hot water from flowing into the cold water path 500, thereby improving the user experience and saving energy.

[0052] The following is a reference appendix. Figures 1-9 A water circuit regulating assembly 100 according to an embodiment of the present invention is described.

[0053] like Figures 1-9 As shown, the water circuit regulating assembly 100 includes: valve body 10, valve element 20 and temperature control element 30.

[0054] The valve body 10 has a hot water pipe 11, a cold water pipe 12, and a connecting pipe 13 that connects the hot water pipe 11 and the cold water pipe 12. For example, the valve body 10 is generally a U-shaped or H-shaped pipe structure. In the pipe connection of the water supply system 1000, the hot water pipe 11 is connected to the hot water circuit 400, and the cold water pipe 12 is connected to the cold water circuit 12. It should be noted that the "connection" here can be a direct connection or an indirect connection.

[0055] In addition, the hot water pipe 11, the cold water pipe 12 and the connecting pipe 13 can be integrally molded parts, which facilitates the processing and molding of the pipeline structure. The valve body 10 can be a copper casting or a stainless steel part.

[0056] Valve element 20 is located inside the connecting pipe 13. When the water pressure in the hot water pipe 11 is greater than the water pressure in the cold water pipe 12, valve element 20 unidirectionally connects the water path from the hot water pipe 11 to the cold water pipe 12. For example, when the water supply system 1000 is first used, the water pump is started, and the water in the hot water path 400 is driven by the water path regulating component 100 to flow back to the cold water path 500. At this time, the water outlet device 300 is in the closed state, and valve element 20 is in the position that connects the hot water pipe 11 and the cold water pipe 12.

[0057] The temperature control element 30 is located inside the connecting pipe 13. When the water path from the hot water pipe 11 to the cold water pipe 12 is open and the water temperature in the connecting pipe 13 reaches a predetermined value, the temperature control element 30 cuts off the connecting pipe 13. In other words, when the water temperature in the hot water path 400 has reached the predetermined value, meaning there is no residual water in the hot water path 400, if the water pressure in the hot water pipe 11 is still greater than the water pressure in the cold water pipe 12, the temperature control element 30 can block the flow of water from the hot water pipe 11 to the cold water pipe 12. This prevents cross-flow between the hot water pipe 11 and the cold water pipe 12. It should be noted that the "predetermined value" refers to the water temperature at which the temperature control element 30 completely cuts off the connecting pipe 13. When the water temperature in the connecting pipe 13 is between the predetermined value and the normal water temperature, the temperature control element 30 can act as a flow cut-off element in the connecting pipe 13. That is, when the water temperature in the connecting pipe 13 has not yet reached the predetermined value, the water flow rate in the connecting pipe 13 can be reduced to a certain extent, reducing the amount of hot water flowing to the cold water pipe 12.

[0058] Since the connecting pipe 13 is equipped with both a valve element 20 and a temperature control element 30, the water circuit regulating component 100 of this embodiment has multiple operating states. When the water supply system 1000 is not in use (i.e., the water supply system 1000 is not supplying hot or cold water), the valve element 20 closes the inlet of the connecting pipe 13, such as... Figure 1 , Figure 4 and Figure 7As shown; when the water supply system 1000 initially uses hot water, valve element 20 opens the inlet of connecting pipe 13, and temperature control element 30 does not cut off connecting pipe 13, allowing water in hot water pipe 11 to flow back to cold water pipe 12, as... Figure 2 , Figure 5 and Figure 8 As shown; when hot water is used externally in the water supply system 1000 for a period of time, and the water temperature in the connecting pipe 13 has reached the predetermined value, valve element 20 opens the inlet of the connecting pipe 13, and temperature control element 30 cuts off the connecting pipe 13, as shown. Figure 3 , Figure 6 and Figure 9 As shown.

[0059] In short, according to the water circuit regulating component 100 of the present invention, the opening and closing of the connecting pipe 13 is controlled by simultaneously providing a valve element 20 and a temperature control element 30 in the connecting pipe 13. In this way, even if the pressurization function is used in the water supply system 1000, crossflow between the hot water channel and the cold water channel can be prevented, reducing the loss of hot water and energy consumption.

[0060] In some embodiments of the present invention, the cold water pipe 12 is provided with an installation interface 121 opposite to the connecting pipe 13. An end cap 14 for sealing the installation interface 121 is provided inside the installation interface 121. The valve element 20 and the temperature control element 30 are assembled into the connecting pipe 13 through the installation interface 121, wherein the valve element 20 is located adjacent to the hot water pipe 11. That is, the installation interface 121 penetrates the wall thickness of the cold water pipe 12, thereby facilitating the installation of the valve element 20 and the temperature control element 30 within the connecting pipe 13, effectively controlling the opening and closing of the connecting pipe 13. By simultaneously installing the valve element 20 and the temperature control element 30 within the connecting pipe 13, residual water backflow is achieved, while crossflow between the hot water channel and the cold water channel branches can be avoided.

[0061] In optional embodiments, such as Figures 1-9 As shown, the end cap 14 forms a first water channel 141 and a second water channel 142 that are interconnected. The first water channel 141 is connected to the connecting pipe 13, and the second water channel 142 is connected to the cold water pipe 12. That is, the end cap 14 not only prevents water leakage from the valve body 10 through the mounting interface 121, but also forms a water channel connecting the cold water pipe 12 and the connecting pipe 13, ensuring unobstructed water flow.

[0062] Some optional examples, such as Figures 1-3As shown, the end cap 14 includes an insertion portion 143 and a closing portion 144. The insertion portion 143 is inserted into the outlet of the connecting pipe 13, forming a first water channel 141. The temperature control element 30 opens or closes the inlet of the first water channel 141. In this embodiment, a valve element 20 is disposed at the inlet of the connecting pipe 13, and the opening degree of the inlet of the connecting pipe 13 is adjusted by the valve element 20. The greater the pressure difference between the hot water pipe 11 and the cold water pipe 12, the greater the opening degree of the inlet of the connecting pipe 13, and vice versa. When there is a pressure difference between the hot water pipe 11 and the cold water pipe 12 and the water temperature in the connecting pipe 13 is equal to or greater than a predetermined value, the temperature control element 30 adjusts the opening degree of the outlet of the connecting pipe 13.

[0063] Optionally, the temperature control element 30 includes at least a telescopic rod 31. When the water temperature in the connecting pipe 13 reaches a predetermined value, the telescopic rod 31 closes the inlet of the first water channel 141. In this embodiment, when the connecting pipe 13 is opened by the valve element 20 and the water temperature in the connecting pipe 13 reaches the predetermined value, the telescopic rod 31 closes the inlet of the first water channel 141. That is, the valve element 20 and the temperature control element 30 respectively control the opening and closing of the inlet and outlet of the connecting pipe 13. It should be noted that when the cold water pipe 12 is supplying cold water, a pressure difference will also occur between the hot water pipe 11 and the cold water pipe 12. At this time, the telescopic rod 31 can also play a throttling role, reducing the proportion of hot water mixed into the cold water pipe 12.

[0064] In other embodiments of the present invention, the temperature control element 30 applies a resisting force to the valve element 20, causing the valve element 20 to close the inlet of the connecting pipe 13. In this embodiment, both the temperature control element 30 and the valve element 20 can jointly control the opening degree of the inlet of the connecting pipe 13. The water circuit regulating assembly 100 includes at least the following two operating states: when the water pressure in the hot water pipe 11 is greater than the water pressure in the cold water pipe 12, and the water temperature in the connecting pipe 13 is lower than a predetermined value, the valve element 20 opens the water circuit from the hot water pipe 11 to the cold water pipe 12. At this time, the temperature control element 30 does not apply force to the valve element 20, and the valve element 20 opens the connecting pipe 13; when the water pressure in the hot water pipe 11 is greater than the water pressure in the cold water pipe 12, and the water temperature in the connecting pipe 13 is at a predetermined value, the temperature control element 30 applies a resisting force to the valve element 20, forcing the valve element 20 to disconnect the connecting pipe 13.

[0065] Optionally, such as Figures 4-6As shown, the end cap 14 includes an abutment portion 145 and a pipe portion 146 connected to each other. The pipe portion 146 forms a first water channel 141 and a second water channel 142. A temperature control element 30 is built into the end cap 14. The temperature control element 30 includes at least a telescopic rod 31. One end of the telescopic rod 31 is connected to the abutment portion 145, and the other end of the temperature control element 30 is disposed opposite to the valve element 20. Thus, when the water pressure in the hot water pipe 11 is greater than the water pressure in the cold water pipe 12, and the water temperature in the connecting pipe 13 is at a predetermined value, the telescopic rod 31 will abut against the valve element 20, causing the valve element 20 to close the inlet of the connecting pipe 13.

[0066] In optional embodiments, such as Figures 7-9 As shown, the valve body 10 also includes a valve housing 15, which is open at both ends. A contact plate 151 is provided at one end of the valve housing 15 adjacent to the cold water pipe 12. The temperature control element 30 is integrated onto the valve element 20. In this embodiment, the valve element 20 and the temperature control element 30 can be uniformly assembled within the valve housing 15 and then installed as a whole into the valve body 10 through the mounting interface 121. After the end cap 14 is installed within the mounting interface 121, it abuts against the valve housing 15, thereby securely fixing the valve housing 15 and the end cap 14 within the connecting pipe 13.

[0067] The temperature control element 30 includes at least one telescopic rod 31. One end of the telescopic rod 31 is connected to the valve element 20, and the other end of the telescopic rod 31 is disposed opposite to the abutment plate 151. When the water temperature in the connecting pipe 13 reaches a predetermined value, the telescopic rod 31 abuts against the abutment plate 151. In this embodiment, the telescopic rod 31 is usually connected to the valve element 20, and the telescopic rod 31 and the valve element 20 are integrated as a whole and built into the valve housing 15, and can move synchronously with each other. When the water temperature in the connecting pipe 13 has reached the predetermined value, and the valve element 20 cannot reset and close the inlet of the connecting pipe 13 in time, the telescopic rod 31 can abut against the abutment plate 151 due to the water temperature, causing the valve element 20 to disconnect the connecting pipe 13.

[0068] In optional embodiments, such as Figures 1-9 As shown, the valve element 20 includes at least: a valve plug 21, a push rod 22, and an elastic element 23. The elastic element 23 is sleeved on the push rod 22. When the water pressure in the hot water pipe 11 is less than or equal to the water pressure in the cold water pipe 12, the elastic element 23 applies a pushing force to the push rod 22, causing the valve plug 21 to reset, thereby sealing the inlet of the connecting pipe 13. The valve plug 21 and the push rod 22 can be a single integral component, such as... Figures 1-6 As shown, valve plug 21 and push rod 22 can also be two independent components connected to each other, such as Figures 7-9 As shown. The operating principle of valve element 20 is known to those skilled in the art and will not be described in detail here.

[0069] Optionally, at least a portion of the telescopic rod 31 is made of a phase change material, and its length extends or shortens as the water temperature inside the connecting pipe 13 changes. The phase change material has the property of absorbing heat and expanding, releasing heat and shortening. As the water temperature inside the connecting pipe 13 rises, the telescopic rod 31 gradually absorbs heat and extends. Thus, when the valve element 20 connects the connecting pipe 13 and the water temperature reaches a predetermined value, the length of the telescopic rod 31 can reach the point of closing the inlet of the first water channel 141 and cutting off the connecting rod, or it can apply a resisting force to the valve element 20, causing the valve element 20 to disconnect the connecting pipe 13. When the water temperature inside the connecting pipe 13 gradually decreases, the telescopic rod 31 releases heat and its length shortens, thereby opening the inlet of the first water channel 141, or the telescopic rod 31 moves away from the valve element 20, causing the valve element 20 to connect the connecting pipe 13.

[0070] like Figures 1-9 As shown, the telescopic rod 31 is equipped with a return spring 32. In this way, after the water temperature in the connecting pipe 13 decreases, the return spring 32 can apply a restoring force to the telescopic rod 31, so that the telescopic rod 31 can return to its original position as soon as possible.

[0071] The water supply system 1000 according to an embodiment of the present invention includes the water circuit regulating component 100 of the above embodiment. Since the water circuit regulating component 100 according to an embodiment of the present invention can ensure that the water supply system 1000 has both zero cold water and pressurization functions, it avoids cross-flow of hot and cold water and saves energy. Therefore, the water supply system 1000 according to an embodiment of the present invention has a good user experience and low energy consumption.

[0072] In some alternative embodiments, such as Figure 10 As shown, the water supply system 1000 includes a heating device 200 and a water outlet device 300. A hot water path 400 and a cold water path 500 are arranged in parallel between the heating device 200 and the water outlet device 300. A hot water pipe 11 is connected in series with the hot water path 400, and a cold water pipe 12 is connected in series with the cold water path 500. The cold water path 500 is connected to both the cold water inlet of the heating device 200 and the municipal tap water supply. The hot water path 400 is connected to the hot water inlet of the heating device 200. Therefore, the cold water path 500 can supply cold water to the heating device 200 and also supply cold water to other devices. At the beginning of use, residual water in the hot water path 400 can flow back to the cold water path 500 through the water path regulating component 100, and then enter the heating device 200 for heating. That is, the cold water circuit 500, the water circuit regulating component 100, the hot water circuit 400 and the heating device 200 form a closed heating water circuit. After the water temperature of the hot water circuit 400 reaches the predetermined value, the connecting pipe 13 in the water circuit regulating component 100 is disconnected.

[0073] Hot water circuit 400 and cold water circuit 500 can be connected in parallel. In this way, a mixing valve can be installed at the outlet of hot water circuit 400 and cold water circuit 500 to adjust the hot water volume and cold water volume, thereby obtaining a more comfortable water temperature.

[0074] In a water supply system 1000 with multiple water outlet devices 300, the water flow regulating component 100 is placed at the last water outlet device 300. This reduces the number of water flow regulating components 100 required for the water supply system 1000, thus saving costs. Of course, one water flow regulating component 100 can also be installed for each water outlet device 300, depending on the customer's needs.

[0075] In other embodiments, such as Figure 11 As shown, the heating equipment includes a heating device 200 and a water outlet device 300. A hot water path 400 and a cold water path 500 are arranged in parallel between the heating device 200 and the water outlet device 300. A return water path 600 is also connected between the hot water path 400 and the cold water path 500. A hot water pipe 11 is connected in series with the return water path 600, and a cold water pipe 12 is connected in series with the cold water path 500. That is, a separate return water path 600 is provided between the hot water path 400 and the cold water path 500. This allows residual water in the hot water path 400 to be quickly returned to the heating device 200 for heating, preventing hot water from entering the cold water path 500.
