[0002] The water circuit assembly system is a water heater that uses natural gas as energy and is used for heating and providing domestic hot water. In the existing water circuit assembly system, when users need hot water, they need to drain the cold water in the pipe before they can get hot water, which wastes water resources and affects user experience. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a water outlet valve, and the technical solution is as follows:

[0004] A water outlet valve is connected to a heat exchange structure in a water circuit component system, the water outlet valve includes a second valve part, the second valve part is provided with a first connecting interface, a second connecting interface, a third connecting interface and a domestic water outlet interface, the first connecting interface is connected to the second connecting interface, the domestic water outlet interface is connected to the third connecting interface, the first connecting interface is connected to the heat exchange structure; the first connecting interface, the second connecting interface and the third connecting interface can form a second circulation loop of unidirectional flow, and the water in the second circulation loop can circulate through the heat exchange structure for heat exchange to provide domestic hot water to the domestic water outlet interface.

[0005] Such an arrangement enables the water in the second flow path to cyclically exchange heat with the heat exchange structure, ensuring that the water in the second flow path is always hot. When a user needs hot water, he or she can get hot water immediately without waiting, thus avoiding wasting water resources.

[0006] In one embodiment, the water circuit assembly system includes a power element, the second communication interface is used to connect to an inlet of the power element, and the third communication interface is used to connect to an outlet of the power element.

[0007] Such a setting can reduce the impact of water flow on components such as the water flow sensor and the flow limiting ring on the water inlet valve, and can effectively protect such components. In addition, the power element is set on the water outlet valve, and there is no obstruction at the front end of the power element, which can reduce the flow loss of water flow and avoid dry pumping of the power element due to excessive water flow resistance at the front end of the power element, causing negative pressure in the pipeline.

[0008] In one embodiment, the second communication interface is disposed opposite to the first communication interface, and the third communication interface and the second communication interface are independent and separated from each other in the second valve portion.

[0009] Such a configuration facilitates installation and can provide space for connecting other components between the second communication interface and the third communication interface.

[0010] In one embodiment, the water outlet valve includes a three-way valve portion connected to the heat exchange structure, a three-way valve cavity is defined in the three-way valve portion, and the three-way valve cavity is separated from the first communication interface, the second communication interface, and the third communication interface in the second valve portion.

[0011] Such an arrangement can protect the components in the three-way valve cavity from being affected by the power components.

[0012] In one embodiment, the water outlet valve also includes a valve core assembly located in the three-way valve cavity, and the valve core assembly can move along the axial direction of the water outlet valve. The valve core assembly includes a valve stem, a first sealing seat and a second sealing seat. A first sleeve is provided in the three-way valve cavity. The valve cavity includes a second cavity, a first cavity and a heating water outlet cavity. The first sealing seat and the second sealing seat can respectively cooperate with the first sleeve to selectively block the gap between the second cavity and the first cavity or the gap between the first cavity and the heating water outlet cavity.

[0013] This arrangement is used to achieve three-way switching.

[0014] In one embodiment, a bypass flow channel and a water outlet channel are provided in the three-way valve portion, the heating water outlet chamber is connected to the bypass flow channel, the second chamber is respectively connected to the water outlet channel and the bypass flow channel, and a first one-way valve is provided in the bypass flow channel, and the first one-way valve is used for one-way conduction of water from the bypass flow channel to the second chamber.

[0015] With such an arrangement, when the valve core assembly is located at the upper part and needs to be moved downward, water can flow from the inlet into the first chamber, and then from the first chamber into the heating water outlet chamber, and a portion of the water flows from the heating water outlet chamber into the second chamber, so that the pressure in the second chamber is balanced with that in the first chamber, thereby enabling the valve core assembly to be moved downward smoothly, thereby preventing the valve core assembly from being supported by high pressure and causing the valve core assembly to be unable to move downward.

[0016] In one embodiment, the three-way valve portion is further provided with a plug hole connected to the water outlet channel, and the plug hole is used to plug in a measuring element.

[0017] With this arrangement, the state of water in the water channel can be detected.

[0020] With this arrangement, when users need water, they can get hot water in time, which improves user experience and increases the utilization rate of water resources.

[0021] In one embodiment, the water circuit component system also includes a water outlet end, which is connected to the domestic water outlet interface. A second one-way valve is provided on the second circulation loop, and the inlet of the second one-way valve is respectively connected to the domestic water outlet interface and the water outlet end, and the outlet of the second one-way valve is connected to the domestic water inlet interface.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time. When a component is considered to be "fixed to" another component, it may be directly fixed on the other component or there may be a central component at the same time.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0042] See also Figures 1 to 12 The present invention provides a water channel component system 100, which can meet the heating needs of each room and provide constant temperature sanitary hot water for use in family bathing, kitchen and other places.

[0043] See also Figure 2 The water circuit assembly system 100 includes a combustion chamber 10, a heat exchange structure 20, a water inlet valve 30 and a water outlet valve 40. The water outlet valve 40 and the water inlet valve 30 are respectively installed at both ends of the heat exchange structure 20. The water inlet valve 30 and the water outlet valve 40 are respectively connected to the combustion chamber 10 through pipes. The combustion chamber 10 is usually installed on the wall of the room. The water inlet valve 30 can provide water to the combustion chamber 10. The water heated by the combustion chamber 10 enters the heat exchange structure 20 through the water outlet valve 40 for heat exchange. The water after heat exchange is returned to the combustion chamber 10 for heating, forming a first circulation loop.

[0044] The first circulation loop is provided with a wall-mounted boiler circulation pump 11 to provide power for the water circulation in the first circulation loop. The water inlet valve 30 is also provided with a water pump interface 34, and the wall-mounted boiler circulation pump 11 is connected to the water pump interface 34.

[0045] Specifically, the water outlet valve 40 includes a three-way valve portion 410 and a second valve portion 41 connected to each other, and the three-way valve portion 410 and the second valve portion 41 are integrally formed. A heating water outlet interface 411 is provided at one end of the three-way valve portion 410, and a heating water inlet interface 32 is provided at the water inlet valve 30, and the heating water inlet interface 32 is connected to the water pump interface 34. A part of the water coming out of the combustion chamber 10 enters the heat exchange structure 20 from the water outlet valve 40 for heat exchange, and a part enters the water outlet valve 40 and flows out from the heating water outlet interface 411 of the water outlet valve 40 to provide hot water for heating to the user. The cooled heating water enters the heating water inlet interface 32 of the water inlet valve 30, and returns to the combustion chamber 10 through the water pump interface 34, forming a heating water circuit.

[0046] Furthermore, a domestic water outlet interface 412 is provided on the second valve part 41, and the water circuit assembly system 100 also includes a water outlet end 60, and the domestic water outlet interface 412 is connected to the water outlet end 60, which is used to provide domestic hot water to the bathroom, kitchen or other places where hot water is needed. The water inlet valve 30 is also provided with a domestic water inlet interface 31 and a second outlet interface 33, and the domestic water inlet interface 31 is connected to the second outlet interface 33 to form a first flow path, the domestic water inlet interface 31 is connected to an external water source, and the second outlet interface 33 is connected to the heat exchange structure 20, and the water entering the domestic water inlet interface 31 passes through the second flow path, and then enters the heat exchange structure 20 from the second outlet interface 33, exchanges heat with the hot water from the combustion chamber 10, and flows out from the domestic water outlet interface 412 after being heated to form a domestic water circuit.

[0047] See also Figure 5 The second valve part 41 is provided with a first communication interface 413 and a second communication interface 414 which are interconnected. The first communication interface 413 is connected to the heat exchange structure 20. The second valve part 41 is also provided with a third communication interface 405 which is connected to the domestic water outlet interface 412. The first communication interface 413, the second communication interface 414 and the third communication interface 415 can form a second flow path for unidirectional flow. The water in the second flow path can cyclically exchange heat through the heat exchange structure 20 to provide domestic hot water to the domestic water outlet interface 412. It can be understood that since the water in the second flow path can flow unidirectionally and cyclically, it can be ensured that the water in the second flow path is always hot, and hot water can be provided to the domestic water outlet interface 412 at any time, realizing zero cold water supply.

[0048] In this embodiment, the heat exchange structure 20 is a plate heat exchanger. In other embodiments, the heat exchange structure 20 may also be a floor heating or other heat exchange structure, as long as it can provide heat to the water in the second flow path.

[0049] The first flow path and the second flow path are connected through the domestic water outlet interface 412 and the heat exchange structure 20 to form a second circulation loop, and the water in the first circulation loop exchanges heat with the water in the second circulation loop through the heat exchange structure 20. The water in the second water circulation loop is always hot, and when the water outlet 60 needs hot water, hot water can be directly obtained. If the second circulation loop is not set, it is necessary to use an external water source, such as the water pressure of tap water, to make the water in the domestic water circuit flow, and once the external water source is closed, the water in the domestic water circuit loses power, and the water in the domestic water circuit will slowly cool down. When the user needs hot water, the cold water in the domestic water circuit needs to be drained before hot water can be obtained, which causes a bad user experience and wastes water resources.

[0050] The orientation of the first connecting interface 413 is opposite to that of the second connecting interface 414, and the axis of the second connecting interface 414 is perpendicular to the axis of the third connecting interface 405, so that there is enough space between the second connecting interface 414 and the third connecting interface 405 to install other components, and the second connecting interface 414 and the third connecting interface 405 are independent and separated from each other in the second valve portion 41, that is, the second connecting interface 414 and the third connecting interface 405 are not connected in the second valve portion 41, and need to be connected through an external component. Such an arrangement facilitates the installation of other components between the two.

[0051] The water circuit assembly system 100 further includes a connecting pipe 42 and a power element 43, wherein both ends of the connecting pipe 42 are respectively connected to the second communication interface 414 and the third communication interface 405, and the power element 43 is disposed between the first communication interface 413 and the third communication interface 405 and is respectively connected to the first communication interface 413 and the third communication interface 405 through the connecting pipe 42. The power element 43 is used to circulate the water in the second circulation loop. In this embodiment, the power element 43 is a circulating water pump. In other embodiments, the circulating power can also be formed by the principle that cold water sinks and hot water floats, or other power elements can be used to circulate the water.

[0052] It can be understood that there are no components on the second valve part 41, and the power element 43 is arranged on the second valve part 41, which will not cause damage to the components. In addition, since there are only the first communication interface 413 and the second communication interface 414 at the front end of the power element 43, and there are no components, the flow resistance of water can be reduced. If the water at the front end of the power element 43 has a large flow resistance, the power element 43 will be dry-drawn, causing the pipeline in front of the power element 43 to be damaged due to negative pressure; if the power element 43 is arranged on the water inlet valve 30, since the water inlet valve 30 is provided with components such as a water flow sensor (not shown) and a current limiting ring (not shown), the power generated by the power element 43 will produce an impact force on the water flow sensor and the current limiting ring, causing damage to the above components.

[0053] The connecting pipe 42 is detachably connected to the second communication port 414 and the third communication port 405 respectively for easy installation.

[0054] Please continue to see Figure 2 A second one-way valve 50 is provided in the second circulation loop, and the inlet of the second one-way valve 50 is respectively connected to the water outlet end 60 and the domestic water outlet interface 412 of the water outlet valve 40, and the outlet of the second one-way valve 50 is connected to the domestic water inlet interface 31 of the water inlet valve 30, so as to realize the one-way conduction of water from the domestic water outlet interface 412 of the water outlet valve 40 to the domestic water inlet interface of the water inlet valve 30, thereby preventing unheated water from directly flowing out of the water outlet end 60, thereby causing the user to obtain cold water.

[0055] See also Figure 8 The three-way valve portion 410 is provided with a three-way valve cavity 415, and the three-way valve cavity 415 is not connected with the first connecting interface 413, the second connecting interface 414 and the third connecting interface 405. With such a configuration, the devices in the three-way valve cavity 415 will not be affected by the power element 43, and the front end of the power element 43 only has the first connecting interface 413 and the second connecting interface 414, which will not increase the flow resistance of water and cause the power element 43 to dry out.

[0056] A water outlet channel 417 connected to the three-way valve cavity 415 is provided in the three-way valve portion 410, and one end of the water outlet channel 417 passes through the valve wall of the three-way valve portion 410 to form a first outlet interface 4171. The three-way valve portion 410 is also provided with an inlet interface 416, and the first outlet interface 4171 is connected to the heat exchange structure 20, and the inlet interface 416 is connected to the combustion chamber 10. The hot water coming out of the combustion chamber 10 enters the three-way valve cavity 415 from the inlet interface 416, and then enters the first outlet interface 4171 or the heating water outlet interface 411.

[0057] See also Figure 4 The three-way valve portion 410 is also provided with a socket 419, which is connected to the water outlet channel 417. The socket 419 is used to connect a measuring element (not shown). The measuring element is sealedly connected to the socket 419 and is used to monitor the state of water in the water outlet channel 417, such as measuring water temperature, pressure and other data.

[0058] See also Figure 6 and Figure 8 The water outlet valve 40 also includes a valve core assembly 44, which is arranged in the three-way valve chamber 415. A first sleeve 4154 is arranged in the three-way valve chamber 415. The cooperation between the valve core assembly 44 and the first sleeve 4154 divides the three-way valve chamber 415 into a first chamber 4151, a second chamber 4152 and a heating water outlet chamber 4153. The first chamber 4151 is communicated with the inlet interface 416, the second chamber 4152 is communicated with the water outlet channel 417, and the heating water outlet chamber 4153 is communicated with the heating water outlet interface 411.

[0059] See also Fig. 9The valve core assembly 44 includes a valve stem 441, a first sealing seat 442 and a second sealing seat 443. The first sleeve 4154 includes a first portion 4155 and a second portion 4156. The first portion 4155 and the second portion 4156 are respectively sealed and connected to the inner wall of the three-way valve chamber 415. The first portion 4155 is located between the first chamber 4151 and the second chamber 4152. The second portion 4156 is located between the first chamber 4151 and the heating water outlet chamber 4153. The first sealing seat 442 can block the first portion 4155, and the second sealing seat 443 can block the second portion 4156. The valve stem 441 is respectively inserted into the first sealing seat 442 and the second sealing seat 443. The valve stem 441 can move along the axial direction of the water outlet valve 40, thereby driving the first sealing seat 442 and the second sealing seat 443 to move along the axial direction of the water outlet valve 40. When the valve stem 441 moves upward, the first sealing seat 442 blocks the first part 4155, and the second sealing seat 443 and the second part 4156 are spaced apart. At this time, the inlet interface 416, the first cavity 4151, the heating water outlet cavity 4153 and the heating water outlet interface 411 are connected; when the valve stem 441 moves downward, the second sealing seat 443 blocks the second part 4156, and the first sealing seat 442 and the first part 4155 are spaced apart. At this time, the inlet interface 416, the first cavity 4151, the second cavity 4152, the water outlet channel 417 and the first outlet interface 4171 are connected, thereby realizing three-way switching.

[0060] Furthermore, a bracket 4157 is provided between the first portion 4155 and the second portion 4156 , and the valve stem 441 is inserted into the bracket 4157 . The bracket 4157 is used to support the first portion 4155 and the second portion 4156 , and plays a fixing role for the valve stem 441 .

[0061] Preferably, the bracket 4157 is in an "H" shape, including two side rods 4157a and a cross rod 4157b, the two side rods 4157a are respectively arranged on both sides of the valve stem 441, and the two ends of the two side rods 4157a are respectively abutted against the first part 4155 and the second part 4156, the two ends of the cross rod 4157b are respectively connected to the two side rods 4157a, and the cross rod 4157b is provided with a second sleeve 4157c, and the valve stem 441 is penetrated in the second sleeve 4157c. Such an arrangement can not only support and guide the first part 4155, the second part 4156 and the valve stem 441, but also reduce the pressure loss of water entering from the water inlet interface.

[0062] See also Figure 6The outlet valve 40 further includes a driving mechanism 45, which is disposed outside the three-way valve portion 410 and connected to the valve stem 441. The driving mechanism 45 can drive the valve core assembly 44 to reciprocate up and down. A first elastic member 444 is disposed between the first portion 4155 and the driving mechanism 45, and a second elastic member 445 is disposed between the second portion 4156 and the first portion 4155. The first elastic member 444 and the second elastic member 445 are both sleeved outside the valve stem 441 to reset the valve core assembly 44. In this embodiment, the driving mechanism 45 is a synchronous motor. In other embodiments, according to different designs of the valve core assembly 44, the driving mechanism 45 can also be a stepping motor or other driving mechanisms 45.

[0063] Specifically, a first bypass port 4153a is provided on the inner wall of the heating water outlet chamber 4153, a second bypass port 4152a is provided on the inner wall of the second chamber 4152, and a bypass flow channel 418 is provided in the three-way valve portion 410. The bypass flow channel 418 is connected to the heating water outlet chamber 4153 through the first bypass port 4153a, and is connected to the second chamber 4152 through the second bypass port 4152a. A first one-way valve 4181 is provided in the bypass flow channel 418. The first one-way valve 4181 is used for one-way conduction of water from the heating water outlet chamber 4153 to the second chamber 4152. When the water pressure in the inlet interface 416 is relatively high, the valve core assembly 44 cannot move downward due to the high pressure, and the driving mechanism 45 will continue to work, causing damage to the driving mechanism 45. The bypass channel 418 can increase the pressure in the second chamber 4152, thereby preventing the valve core assembly 44 from being unable to move downward due to the high pressure; and, since the heating water outlet chamber 4153 has a relatively large space, the first bypass port 4153a is set on the inner wall of the heating water outlet chamber 4153, which can reduce the flow resistance of water entering the bypass channel 418; the first one-way valve 4181 can prevent water from flowing back from the second chamber 4152 to the heating water outlet chamber 4153.

[0064] See also Figures 1 to 3 The water outlet valve 40 further includes a fastening structure 46 , and the fastening structure 46 is used to fasten the connection between the connecting pipe 42 and the second valve part 41 .

[0065] Specifically, the fastening structure 46 includes a first fastening member 461, a second fastening member 462, a first fastening block 463 and a second fastening block 464. The first fastening block 463 and the second fastening block 464 are fixed on the second valve portion 41. A first fastening hole 401 is provided on the second valve portion 41 outside the second communication interface 414. The first fastening hole 401 is communicated with the second communication interface 414. A second fastening hole 402 is provided on the second valve portion 41 outside the third communication interface 405. A first fastening groove (not shown) and a second fastening groove (not shown) are respectively provided on the outer side walls at both ends of the connecting pipe 42. Both ends of the connecting pipe 42 are respectively inserted into the second communication interface 414 and the third communication interface 405. The first fastening member 461 and the second fastening member 462 are respectively inserted into the first fastening hole 401 and the second fastening hole 402 and extend into the first fastening groove and the second fastening groove, and respectively abut against the groove walls of the first fastening groove and the second fastening groove. The first fastening block 463 and the second fastening block 464 are used to fasten the first fastening member 461 and the second fastening member 462 to fix the connection between the connecting pipe 42 and the second valve portion 41 .

[0066] Furthermore, the first fastener 461 and the second fastener 462 are both "U"-shaped, and the first fastener 461 and the second fastener 462 have two first insertion arms 4611.

[0068] During operation, under the action of the power element 43, water flows out from the domestic water outlet interface 412, passes through the second one-way valve 50, enters the domestic water inlet interface 31 of the water inlet valve 30, and then enters the heat exchange structure 20 to perform heat exchange with the hot water from the combustion chamber 10. The heated water enters the water outlet valve 40 through the first connecting interface 413, flows through the power element 43 from the second connecting interface 414, and then enters from the third connecting interface 405, and flows out through the domestic water outlet interface 412 to form a zero cold water circulation loop. In this way, it is ensured that the water in the second circulation loop is always hot. And by setting the power element 43 on the water outlet valve 40, since there are no components at the front end of the power element 43, it will not cause damage to the components, and will not increase the flow resistance of the water, which can ensure the normal operation of the pipeline.
