Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household appliances, and particularly relates to a wall-hanging stove water system. BACKGROUND

[0002] The wall-hanging stove water system is a water heater using natural gas as energy, which has a powerful central heating function for a family, can meet the heating demand of multiple rooms, and can provide domestic water for bathing, kitchen and other places. The water inlet valve and the water outlet valve are essential structures in the wall-hanging stove water system. The main function of the water inlet valve is to regulate the water flow entering the wall-hanging stove, ensure the normal operation of the wall-hanging stove, and add water to the wall-hanging stove when the water in the wall-hanging stove is insufficient, so as to ensure the continuity of hot water supply. The main function of the water outlet valve is to control the opening and closing of the water inlet and outlet, shunt, and control the direction and flow of water flow, so as to ensure the uniform delivery of hot water in the pipeline and the normal heating of the heating radiators.

[0003] Specifically, the tap water in the water supply channel entering the heat exchange plate through the water inlet valve can exchange heat with the hot water in the heat exchange channel of the heat exchange plate, so as to increase the temperature of the tap water, and flow out of the outlet of the bathroom channel of the water outlet valve to provide domestic hot water for users. However, the user will intermittently close the shower to save water when taking a bath. When the shower is in the closed state, the water in the water supply channel will continue to exchange heat with the hot water in the heat exchange channel, causing the water temperature to continue to rise; when the shower is opened again, there is a risk of scalding the user when the hot water with high temperature in the water supply channel flows out.

[0068] Before any embodiments of the present utility model are explained in detail, it is to be understood that the present utility model is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the above-described accompanying drawings.

[0069] In the present application, the terms "comprise", "contain", "have" or any other variant thereof are intended to cover a non-exclusive inclusion, so that a process, method, article or device that includes a list of elements not only includes those elements, but also includes other elements not expressly listed or inherent to such process, method, article or device. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of another identical element in the process, method, article or device that includes the element.

[0070] In the present application, the term "and / or" is a description of the association relationship of the associated objects, which means that there can be three kinds of relationships. For example, A and / or B can represent three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents a "and / or" relationship between the front and rear associated objects.

[0071] In the present application, the terms "connection", "combination", "coupling" and "installation" can be direct connection, combination, coupling or installation, or indirect connection, combination, coupling or installation. Among them, direct connection means that two parts or components are connected together without setting intermediate parts, and indirect connection means that two parts or components are connected with at least one intermediate part, and the two parts or components are connected through the intermediate part. In addition, "connection" and "coupling" are not limited to physical or mechanical connection or coupling, and can include electrical connection or coupling.

[0072] In the present application, those skilled in the art will understand that the relative terms used in connection with the number or condition (for example, "about", "approximately", "substantially" and the like) include the values indicated by the context. For example, the relative terms at least include the error degree related to the measurement of the specific value, the tolerance caused by manufacturing, assembly, use and the like related to the specific value. Such terms should also be regarded as disclosing the range defined by the absolute values of the two endpoints. The relative term can refer to the addition or subtraction of a certain percentage (for example, 1%, 5%, 10% or more) of the indicated value. The numerical value without the relative term should also be disclosed as a specific value with tolerance. In addition, "substantially" when expressing the relative angular positional relationship (for example, substantially parallel, substantially perpendicular), can refer to the addition or subtraction of a certain degree (for example, 1 degree, 5 degrees, 10 degrees or more) based on the indicated angle.

[0073] In the present application, those skilled in the art will understand that the functions performed by the components can be performed by one component, multiple components, one part, or multiple parts. Similarly, the functions performed by the parts can also be performed by one part, one component, or multiple parts in combination.

[0074] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and the like are described in the orientation and positional relationship shown in the drawings, and should not be construed as limiting the embodiments of the present application. In addition, it should also be understood in the context that when referring to one element connected to another element "on" or "under", it can be directly connected to another element "on" or "under", or indirectly connected to another element "on" or "under" through an intermediate element. It should also be understood that the terms "upper", "lower", "left", "right", "front", "back" and the like not only represent the positive direction, but also can be understood as the side direction. For example, the lower side can include the lower side, the lower left side, the lower right side, the front lower side and the back lower side.

[0075] Figure 1 A first structure schematic diagram of the wall-mounted stove water system provided by the embodiment is shown. Figure 2 A second structure schematic diagram of the wall-mounted stove water system provided by the embodiment is shown. Figure 3 A waterway structure diagram of the wall-mounted stove water system provided by the embodiment is shown. Figures 1-3 As shown, the present application provides a wall-mounted stove water system, which comprises a combustion chamber 200, a heat exchange structure 300, a water inlet valve 100a and a water outlet valve 100b, wherein the combustion chamber 200 can heat the water therein; the heat exchange structure 300 comprises a heat exchange passage 310 and a water supply passage 320 in heat exchange cooperation; the water inlet valve 100a comprises a water inlet valve body 1a, which has a water inlet interface 111a, a second heat exchange inlet channel 112a, a second heat exchange outlet channel 113a and a water pump interface 114a, the water inlet interface 111a is connected in communication with an external water source, the second heat exchange outlet channel 113a is connected in communication with the water pump interface 114a, the second heat exchange inlet channel 112a is connected in communication with the water inlet interface 111a, and the second heat exchange inlet channel 112a and the second heat exchange outlet channel 113a are connected with the inlet of the water supply passage 320 and the outlet of the heat exchange passage 310 respectively, and the water pump interface 114a is connected in communication with the cold water inlet 202 of the combustion chamber 200 through a water supply pump (not shown in the figure); the water outlet valve 100b comprises a water outlet valve body 1b, which has a hot water inlet 111b, a heating passage 121b, a first heat exchange inlet channel 131b, a first heat exchange outlet channel 132b and a bathroom passage 133b, the hot water inlet 111b is connected in communication with the hot water outlet 201 of the combustion chamber 200, and the hot water inlet 111b can selectively communicate with the heating passage 121b or the first heat exchange inlet channel 131b, the first heat exchange inlet channel 131b and the first heat exchange outlet channel 132b are connected with the inlet of the heat exchange passage 310 and the outlet of the water supply passage 320 respectively, and the first heat exchange outlet channel 132b is connected in communication with the bathroom passage 133b.

[0076] In working, when the hot water inlet 111b is communicated with the heating channel 121b, the hot water heated by the combustion chamber 200 can flow into the heating system 500 through the hot water outlet 201, the connecting pipeline 401, the hot water inlet 111b and the heating channel 121b, so as to provide heating demand for the user. The water in the heating system 500 which is heat-exchanged with the outside can flow into the combustion chamber 200 through the water inlet valve 100a to be heated again, so as to form a heating circulation loop. When the hot water inlet 111b is communicated with the first heat-exchange inlet channel 131b, the hot water heated by the combustion chamber 200 can flow into the heat-exchange structure 300 through the hot water outlet 201, the connecting pipeline 401, the hot water inlet 111b and the first heat-exchange inlet channel 131b, and then flow into the heat-exchange channel 310. After being heat-exchanged with the water in the water supply channel 320, the hot water flows into the second heat-exchange outlet channel 113a of the water inlet valve 100a, and then flows back to the combustion chamber 200 through the water pump interface 114a to be heated again, so as to form a heat-exchange circulation loop. The water in the external water source can flow into the water supply channel 320 of the heat-exchange structure 300 through the water inlet interface 111a and the second heat-exchange inlet channel 112a, and then flow into the bathroom system through the first heat-exchange outlet channel 132b of the water outlet valve 100b and the bathroom channel 133b, so as to provide domestic water for the user.

[0077] It should be explained that the heating system 500 specifically refers to the terminal heat dissipation components such as heating radiators, floor heating pipes or fan coil units. The water heated in the combustion chamber 200 can be pumped into the above-mentioned terminal heat dissipation components through the water outlet valve 100b, and then the heat is dissipated to the indoor air through heat dissipation, so as to improve the indoor environment temperature and meet the heating demand of the user. The bathroom system specifically refers to the water device for the user to perform shower, washing and other operations. Therefore, the heating system 500 and the bathroom system are both relatively mature technologies in the field, and the specific structure of the heating system 500 and the bathroom system will not be described herein.

[0078] The material of the connecting pipeline 401 is not limited in the embodiment, which can be purple copper pipe, corrugated pipe, stainless steel pipe or plastic pipe. It should be further explained that the combustion chamber 200 is a relatively mature technology in the field, and the specific structure of the combustion chamber 200 will not be described herein.

[0079] The wall-mounted boiler water system in the related art often has a high overall installation height, which cannot meet the miniaturization demand of the wall-mounted boiler water system. In order to solve this problem, the water outlet valve 100b of the wall-mounted boiler water system provided in the embodiment can fully utilize the space in the thickness direction of the water outlet valve body 1b, so as to reduce the height of the water outlet valve 100b, and then reduce the installation height of the entire wall-mounted boiler water system, so as to meet the miniaturization demand of the wall-mounted boiler water system.

[0080] Figure 4A first structural schematic diagram of the water outlet valve 100b is shown. Figure 5 A second structural schematic diagram of the water outlet valve 100b is shown. Figure 6 A first sectional structural schematic diagram of the water outlet valve 100b is shown. Figures 4-5 And in combination with Figure 3 As shown, in the embodiment, the water outlet valve body 1b has a three-way valve cavity 110b in communication with the hot water inlet 111b, the three-way valve cavity 110b can selectively communicate with the heating channel 121b or the first heat exchange inlet flow channel 131b, and the axis direction of the three-way valve cavity 110b is arranged at an angle with the axis direction of the heating channel 121b. Compared with the prior art scheme of coaxially arranging the three-way valve cavity 110b and the heating channel 121b, the design can arrange the three-way valve cavity 110b and the heating channel 121b in two directions respectively, so as to avoid the case that the length of the water outlet valve body 1b along the axis direction of the three-way valve cavity 110b is too long, thereby optimizing the spatial layout of the entire water outlet valve 100b, reducing the installation height of the wall-hanging stove water system, and meeting the miniaturization demand of the wall-hanging stove water system.

[0081] Specifically, the water outlet valve body 1b includes a three-way valve part 11b, a heating valve part 12b, and a heat exchange valve part 13b, the three-way valve part 11b is provided with the three-way valve cavity 110b described above, and the three-way valve cavity 110b extends along a first direction; the heating valve part 12b is connected to the three-way valve part 11b, the heating valve part 12b is provided with the heating channel 121b described above, and the heating channel 121b extends along a second direction; the heat exchange valve part 13b is connected to one side of the three-way valve part 11b and the heating valve part 12b along a third direction, and the first heat exchange inlet flow channel 131b, the first heat exchange outlet flow channel 132b, and the bathroom channel 133b are all provided in the heat exchange valve part 13b; the first direction, the second direction, and the third direction are arranged at an angle with each other, which can make the entire structural size of the water outlet valve body 1b be distributed in three directions arranged at an angle with each other in three-dimensional space, further avoiding the case that the length of the water outlet valve body 1b along the axis direction of the three-way valve cavity 110b is too long, thereby optimizing the spatial layout of the entire water outlet valve 100b.

[0082] It needs to be explained that, as Figure 4 , Figure 5 And in combination with Figure 1As shown, the height direction of the water outlet valve 100b after actual installation is defined as the up-down direction, wherein the side of the water outlet valve 100b close to the combustion chamber 200 is defined as up, the side of the water outlet valve 100b away from the combustion chamber 200 is defined as down, the side of the water outlet valve 100b close to the heat exchange structure 300 is defined as back, and the side of the water outlet valve 100b away from the heat exchange structure 300 is defined as front; when a user stands facing the front of the water outlet valve 100b, the side of the water outlet valve 100b toward the right hand of the user is defined as right, and the side of the water outlet valve 100b toward the left hand of the user is defined as left. In addition, the height direction of the water outlet valve body 1b refers to the up-down direction, the width direction of the water outlet valve body 1b refers to the left-right direction, and the thickness direction of the water outlet valve body 1b refers to the front-back direction. Among them, the first direction specifically refers to the front-back direction, the second direction specifically refers to the up-down direction, and the third direction specifically refers to the left-right direction.

[0083] In other words, in the present embodiment, the three-way valve part 11b extends along the front-back direction, the heating valve part 12b is connected to the lower part of the three-way valve part 11b, and the heat exchange valve part 13b is connected to the right side of the three-way valve part 11b and the heating valve part 12b, so that the entire water outlet valve body 1b is arranged in a substantially square shape, fully utilizes the space of the water outlet valve body 1b in the width direction and the thickness direction, greatly reduces the installation height of the entire wall-mounted stove water system, and optimizes the space layout of the entire system.

[0084] Optionally, as shown, Figure 6 The three-way valve cavity 110b includes a first cavity 1102b, a main valve cavity 1101b and a second cavity 1103b which are sequentially communicated along the first direction, the main valve cavity 1101b is communicated with the hot water inlet 111b, and the main valve cavity 1101b can selectively communicate the first cavity 1102b or the second cavity 1103b; the heating channel 121b is communicated with the first cavity 1102b, and the first heat exchange inlet flow channel 131b is communicated with the second cavity 1103b. When the main valve cavity 1101b is communicated with the first cavity 1102b, the hot water in the combustion chamber 200 can be circulated in the heating water circulation loop; when the main valve cavity 1101b is communicated with the second cavity 1103b, the hot water in the combustion chamber 200 can be circulated in the heat exchange circulation loop.

[0085] Optionally, the water outlet valve 100b further comprises a switching mechanism 5b movably arranged in the three-way valve cavity 110b to selectively connect the heating passage 121b or the first heat exchange inlet channel 131b. That is, by moving the switching mechanism 5b in the three-way valve cavity 110b, the passage between the main valve cavity 1101b and the first cavity 1102b or the passage between the main valve cavity 1101b and the second cavity 1103b can be selectively opened to realize three-way switching. The specific structure and working principle of the switching mechanism 5b will not be described here. Any switching mechanism that can be applied to the water outlet valve 100b to realize three-way switching in the three-way valve cavity 110b in the prior art is within the scope of the present embodiment.

[0086] Further, the water outlet valve 100b further comprises a driving mechanism 4b, the output end of the driving mechanism 4b being connected to the switching mechanism 5b to drive the switching mechanism 5b to move in the three-way valve cavity 110b. In the present embodiment, the driving mechanism 4b is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 5b, the driving mechanism 4b can also be a stepper motor, a servo motor or other driving devices.

[0087] It should be noted that by arranging the three-way valve part 11b in the front-rear direction, the driving mechanism 4b can also be installed on the front side of the water outlet valve body 1b (the driving mechanism in the prior art is usually installed between the water outlet valve body and the combustion chamber, i.e. the driving mechanism is installed on the upper part of the water outlet valve body), so as to avoid the spacing area between the water outlet valve body 1b and the combustion chamber 200, fully utilize the space of the water outlet valve body 1b in the thickness direction, further shorten the distance between the water outlet valve body 1b and the combustion chamber 200, and reduce the height of the entire wall-mounted stove water system.

[0088] To ensure the stability of the water pressure in the wall-mounted stove water system and realize reasonable control of the circulating water flow, the water outlet valve 100b in the related art often needs to be externally connected with a bypass pipe with water replenishing function, but the externally connected bypass pipe often occupies a large amount of installation space of the water outlet valve 100b, which is not conducive to the installation of the water outlet valve 100b in a narrow space such as a control cabinet or a valve well. To solve this problem, as shown in Figure 4 and Figure 5 In the present embodiment, the water outlet valve 100b further comprises an automatic water replenishing assembly 2b configured to guide the water in the first heat exchange outlet channel 132b into the first heat exchange inlet channel 131b to replenish water into the heat exchange passage 310 to prevent dry burning of the wall-mounted stove water system and affect the service life of the entire wall-mounted stove water system.

[0089] Figure 7 Fig. 2 shows a second cross-sectional structure schematic view of the water outlet valve 100b provided by the present embodiment. As shown in Figure 7 and in combination with Figure 4As shown, the water outlet valve body 1b is further provided with a water replenishment inlet flow channel 1341b, a water replenishment outlet flow channel 1342b and a third communication port 1343b capable of communicating the two, the water replenishment inlet flow channel 1341b is in communication with the first heat exchange outlet flow channel 132b, and the water replenishment outlet flow channel 1342b is in communication with the first heat exchange inlet flow channel 131b; the automatic water replenishment assembly 2b is adjustably mounted on the water outlet valve body 1b, and the output end of the automatic water replenishment assembly 2b can move towards or away from the third communication port 1343b, so as to selectively open the passage (i.e. the third communication port 1343b) between the water replenishment inlet flow channel 1341b and the water replenishment outlet flow channel 1342b. By arranging the automatic water replenishment assembly 2b, when the heating water circuit is short of water, the output end of the automatic water replenishment assembly 2b can move away from the third communication port 1343b to open the third communication port 1343b, so that the water in the first heat exchange outlet flow channel 132b flows into the first heat exchange inlet flow channel 131b through the water replenishment inlet flow channel 1341b, the third communication port 1343b and the water replenishment outlet flow channel 1342b in turn, and then replenishes water into the heating water circuit through the heat exchange structure 300, so as to ensure the stability of the water pressure of the entire wall-mounted boiler water circuit system, and avoid dry burning of the wall-mounted boiler, thereby prolonging the service life of the entire wall-mounted boiler water circuit system; by arranging the water replenishment inlet flow channel 1341b and the water replenishment outlet flow channel 1342b inside the water outlet valve body 1b, the external bypass pipe in the prior art is omitted, thereby reducing the size of the entire water outlet valve 100b, further optimizing the spatial layout of the water outlet valve 100b, and reducing the material cost to a certain extent.

[0090] Figure 8 A cross-sectional structure schematic diagram of the automatic water replenishment assembly 2b provided by the present embodiment is shown. As shown in the figure, Figure 8 and in combination Figure 7 As shown, the automatic water replenishment assembly 2b is an electromagnetic valve assembly, which includes an electromagnetic coil 21b and a blocking piece 22b, and the electromagnetic coil 21b is mounted on the water outlet valve body 1b; the blocking piece 22b is connected to the output end of the electromagnetic coil 21b, so as to move towards or away from the third communication port 1343b under the driving action of the electromagnetic coil 21b. The electromagnetic valve assembly has the advantages of high efficiency, reliability, safety, easy automation control, energy saving, and strong adaptability, and can realize automatic and timely water replenishment to the heating water circuit, which can greatly save manpower and improve the user experience.

[0091] In the embodiment, the blocking member 22b comprises a sealing seat 221b connected to the output end of the electromagnetic coil 21b and a sealing pad 222b fixedly installed on the lower side of the sealing seat 221b. The sealing pad 222b can be made of rubber and is soft. The sealing seat 221b supports the sealing pad 222b, thereby achieving good sealing effect. The specific structure and working principle of the electromagnetic coil 21b are prior art and will not be described here.

[0092] As shown in Figure 4 and Figure 6 , the water outlet valve body 1b is provided with a pressure detection member 3b for detecting the pressure in the three-way valve cavity 110b. The pressure detection member 3b is in signal connection with the automatic water replenishing assembly 2b. By arranging the pressure detection member 3b, the water shortage signal of the heating water circuit can be obtained by detecting the pressure in the three-way valve cavity 110b, so as to accurately control the starting time of the automatic water replenishing assembly 2b and realize timely and accurate water replenishment of the heating water circuit. In addition, the water amount in the combustion chamber 200 can also be indirectly obtained by obtaining the pressure in the three-way valve cavity 110b, so as to start the combustion chamber 200 for heating when the water amount is sufficient, thereby avoiding dry burning. The specific structure and detection principle of the pressure detection member 3b will not be described here. The pressure detection members that can be applied to the water outlet valve 100b and can detect the pressure in the three-way valve cavity 110b in the prior art are within the protection scope of the embodiment.

[0093] As shown in Figure 7 , a one-way valve 135b is arranged in the water replenishing and outlet flow channel 1342b to allow fluid (specifically water) to flow from the water replenishing and outlet flow channel 1342b to the first heat exchange inlet flow channel 131b only, thereby avoiding the water in the first heat exchange inlet flow channel 131b flowing back to the first heat exchange outlet flow channel 132b through the water replenishing and outlet flow channel 1342b and affecting the quality of the domestic water. The one-way valve 135b is a relatively mature valve structure in the prior art. The specific structure and working principle of the one-way valve 135b will not be described here.

[0094] Figure 9 A local enlarged view at A is shown. Figure 6 As shown in Figure 9 and in combination with Figure 5 , Figure 6As shown, the water outlet valve body 1b further comprises a bypass valve part 15b connected to the heating valve part 12b, and the bypass valve part 15b has a bypass flow channel 151b and a pressure relief passage 152b in communication with the outside; the bypass flow channel 151b is provided with a bypass valve core 141b and a pressure relief valve core 142b, which are spaced apart and movably arranged, and the space between the two forms a pressure relief main cavity, which is in communication with one side of the three-way valve cavity 110b close to the first heat exchange inlet flow channel 131b; the bypass valve core 141b can selectively open the passage between the heating passage 121b and the pressure relief main cavity, and the pressure relief valve core 142b can selectively open the passage between the pressure relief main cavity and the pressure relief passage 152b. Wherein, the "one side of the three-way valve cavity 110b close to the first heat exchange inlet flow channel 131b" specifically refers to the second cavity 1103b.

[0095] By arranging the bypass valve part 15b and movably arranging the bypass valve core 141b and the pressure relief valve core 142b in the bypass flow channel 151b of the bypass valve part 15b, when the three-way valve cavity 110b is in communication with the heating passage 121b, and the water pressure in the heating passage 121b is high, the water in the heating passage 121b can push the bypass valve core 141b to move to open the passage between the heating passage 121b and the pressure relief main cavity, so that the water in the heating passage 121b flows into the heat exchange structure 300 through the pressure relief main cavity, the three-way valve cavity 110b and the first heat exchange inlet flow channel 131b, thereby playing a pressure relief role and supplementing water for the heat exchange structure 300 to avoid damage of the heat exchange structure 300 due to lack of water and dry burning, thereby ensuring the use safety of the entire wall-mounted stove waterway system; if the pressure in the heating passage 121b is too high, the water circulation in the wall-mounted stove waterway system still cannot play a pressure relief effect, at this time, the water in the pressure relief main cavity can push the pressure relief valve core 142b to move to open the passage between the pressure relief main cavity and the pressure relief passage 152b, thereby making the pressure in the water outlet valve 100b be discharged from the pressure relief passage 152b to the outside, thereby playing a pressure relief role; when the three-way valve cavity 110b is in communication with the first heat exchange inlet flow channel 131b, if the pressure inside the water outlet valve body 1b is high, the water in the pressure relief main cavity can also push the pressure relief valve core 142b to move to open the passage between the pressure relief main cavity and the pressure relief passage 152b, thereby making the pressure in the water outlet valve 100b be discharged from the pressure relief passage 152b to the outside, thereby playing a pressure relief role. The water outlet valve 100b, by arranging the bypass valve core 141b and the pressure relief valve core 142b in the bypass valve part 15b, is equivalent to integrating the bypass valve and the safety valve in the prior art, which can reduce the overall size of the water outlet valve 100b to some extent, facilitate installation, and further ensure the use safety of the entire wall-mounted stove waterway system.

[0096] Optionally, the spring preload of the pressure relief valve core 142b is greater than the spring preload of the bypass valve core 141b. The purpose of this arrangement is that when the internal pressure of the outlet valve body 1b is high, pressure relief can be achieved primarily through the internal water circulation of the boiler's water system. Specifically, water in the heating channel 121b opens the bypass valve core 141b, flowing through the pressure relief main chamber, the three-way valve chamber 110b, and the first heat exchange inlet channel 131b to the heat exchange structure 300. If complete pressure relief cannot be achieved through the internal water circulation of the boiler's water system, the pressure relief valve core 142b opens the passage between the pressure relief main chamber and the pressure relief channel 152b to release the internal pressure of the outlet valve body 1b to the outside. This design reduces the activation frequency of the pressure relief valve core 142b, thereby extending its service life. Optionally, the outlet of the pressure relief channel 152b is set downward so that when the main body of the water outlet valve 1b needs to release pressure to the outside, the water flowing from the main pressure relief chamber to the pressure relief channel 152b can flow out quickly under its own gravity, ensuring the timeliness of the pressure relief process.

[0097] In this embodiment, the bypass valve core 141b is a one-way valve core structure, allowing only water in the heating channel 121b to flow through the pressure relief main chamber to the three-way valve chamber 110b, thus preventing backflow of water in the three-way valve chamber 110b. The one-way valve core structure is a commonly used valve structure in the art, and the specific structure and working principle of the bypass valve core 141b will not be described in detail in this embodiment. Furthermore, this embodiment does not limit the specific structure of the pressure relief valve core 142b; any pressure relief valve core in the prior art that can achieve a pressure relief effect is within the protection scope of this embodiment.

[0098] like Figure 5 As shown, to facilitate maintenance by operators, the bypass valve section 15b is connected to the front side of the heating valve section 12b. Operators can perform maintenance on the outlet valve 100b from the front without disassembling the entire outlet valve 100b, improving operational convenience. In this embodiment, the axial direction of the bypass valve section 15b is parallel to the axial direction of the three-way valve section 11b, meaning the bypass valve section 15b also extends in the front-to-back direction. This design allows the bypass valve section 15b to be located between the three-way valve section 11b and the heating valve section 12b, making the structure of the entire outlet valve 100b more compact, the bypass connection distance shorter, and thus shortening the response time. Of course, in other embodiments, the axial direction of the bypass valve section 15b can also be set at an angle to the axial direction of the three-way valve section 11b. In this example, to facilitate maintenance of the bypass valve section 15b by the operator, the extension direction of the bypass valve section 15b can be set to gradually slope downwards away from the heating valve section 12b, so as to avoid the end of the pressure relief valve core 142b interfering with other structures and affecting the operator's operation.

[0099] In related technologies, the inlet valve 100a is mostly a constant flow rate valve, meaning the flow rate cannot be adjusted during use. However, as the weather changes, the water temperature also changes. When the water temperature is high, the same amount of gas is sufficient to heat the water to a very high temperature. For example, a wall-mounted boiler with a thermal power of 20KW can only heat cold water from 5℃ to 40℃ at a maximum flow rate of 8L / min. When the outside temperature is high in summer, the cold water temperature can reach 25℃. If the flow rate is still limited to 8L / min, the water temperature will rise rapidly, and may even exceed 40℃, scalding the user and affecting the user experience.

[0100] Figure 10 The diagram shows a structural schematic of the inlet valve 100a provided in this embodiment from one perspective. Figure 11 A cross-sectional view of the inlet valve 100a provided in this embodiment is shown. To solve the above problems, such as... Figures 10-11 As shown, in this embodiment, the inlet valve 100a further includes a first flow regulating component 2a. The inlet valve body 1a also has an inlet channel 1221a and an outlet channel 1222a. The inlet of the inlet channel 1221a is connected to the inlet interface 111a, and the outlet of the outlet channel 1222a is connected to the second heat exchange inlet channel 112a. The first flow regulating component 2a is adjustablely installed on the inlet valve body 1a and can selectively open the passage between the inlet channel 1221a and the outlet channel 1222a and regulate the water flow rate in the passage. By setting the first flow regulating component 2a, the water flow rate in the passage between the inlet channel 1221a and the outlet channel 1222a can be adjusted, thereby adjusting the inlet flow rate of the inlet valve 100a to meet different temperature requirements and improve the user experience.

[0101] Optionally, the inlet valve body 1a also has a first connecting port 1251a, and the end of the inlet channel 1221a away from the inlet interface 111a can be connected to the outlet channel 1222a through the first connecting port 1251a; the first flow regulating component 2a includes a servo motor 21a, and the output end of the servo motor 21a is provided with a first blocking part 2121a. The servo motor 21a is disposed on the inlet valve body 1a, and the first blocking part 2121a is located inside the inlet valve body 1a. The servo motor 21a is configured to drive the first blocking part 2121a to move closer to or away from the first connecting port 1251a, so as to adjust the distance between the first blocking part 2121a and the first connecting port 1251a.

[0102] The water inlet valve 100a in the embodiment is provided with the servo motor 21a, and the first blocking part 2121a is arranged at the output end of the servo motor 21a. When the servo motor 21a is started, the first blocking part 2121a can be driven to move close to or away from the first communication port 1251a, so as to adjust the distance between the first blocking part 2121a and the first communication port 1251a, and then adjust the water inflow between the water inlet channel 1221a and the water outlet channel 1222a, so as to meet different water temperature requirements and improve the user experience. By using the above arrangement, the use of the flow limiting ring can be omitted, the material cost is reduced to a certain extent, and the water flow at the water outlet channel 1222a can be flexibly adjusted. In addition, the servo motor 21a has the advantages of high precision, stable operation, high reliability and easy maintenance, and can realize accurate adjustment of the water flow in the water outlet channel 1222a.

[0103] It should be explained that, in actual use, the servo motor 21a can drive the first blocking part 2121a to move between the first position and the second position. When the first blocking part 2121a is located at the first position, the outer contour of the first blocking part 2121a can completely cover the first communication port 1251a, so that the minimum water flow through the first communication port 1251a can be close to 0, thereby increasing the adjustment range of the water flow; when the first blocking part 2121a is located at the second position, the distance between the first blocking part 2121a and the first communication port 1251a is maximum, so that the water flow through the first communication port 1251a is maximum. In the embodiment, the servo motor 21a can drive the first blocking part 2121a to move to any position between the first position and the second position, so that the water flow through the first communication port 1251a is adjusted between the minimum value and the maximum value. The maximum distance between the first blocking part 2121a and the first communication port 1251a is not limited in the embodiment, and the designer can adaptively adjust it according to the model and heat exchange efficiency of the wall-hanging stove.

[0104] Figure 12 The structure schematic diagram of the second valve body 12a provided by the embodiment is shown. Figure 13 The structure schematic diagram of the second valve body 12a provided by the embodiment is shown. Figure 14 The structure schematic diagram of the first valve body 11a provided by the embodiment is shown. Figures 12-14 And combined with Figure 11As shown, the water inlet valve body 1a includes a first valve body 11a and a second valve body 12a, the first valve body 11a is provided with a mounting interface 116a, and the water inlet interface 111a and the second heat exchange inlet channel 112a are both formed on the first valve body 11a; the second valve body 12a includes a water inlet and outlet branch pipe 122a, the water inlet and outlet branch pipe 122a is inserted into the mounting interface 116a, and a partition 1223a is arranged in the water inlet and outlet branch pipe 122a along the axial direction of the water inlet and outlet branch pipe 122a to separate the inner hole channel of the water inlet and outlet branch pipe 122a into a water inlet channel 1221a and a water outlet channel 1222a. By arranging the partition 1223a in the water inlet and outlet branch pipe 122a, the water inlet channel 1221a and the water outlet channel 1222a separated by the partition 1223a in the same branch pipe can be formed, the structure is compact, and the volume of the entire water inlet valve 100a can be reduced to a certain extent.

[0105] Specifically, the first valve body 11a is further provided with a communication water cavity 117a, the communication water cavity 117a is in communication with the mounting interface 116a, the water inlet and outlet branch pipe 122a is inserted into the mounting interface 116a and extends into the communication water cavity 117a, and the water inlet and outlet branch pipe 122a separates the communication water cavity 117a into a water inlet cavity 1171a and a water outlet cavity 1172a, the water inlet cavity 1171a is in communication with the water inlet interface 111a and the water inlet channel 1221a, and the water outlet cavity 1172a is in communication with the water outlet channel 1222a and the second heat exchange inlet channel 112a. After the external cold water flows into the water inlet interface 111a, it flows to the water inlet channel 1221a through the water inlet cavity 1171a, and then flows to the water outlet cavity 1172a from the water outlet channel 1222a.

[0106] Optionally, the cross-sectional area of the water inlet channel 1221a is S1, and the cross-sectional area of the water outlet channel 1222a is S2, wherein S1 / S2<1. That is, the water flow passage of the water inlet channel 1221a is smaller than that of the water outlet channel 1222a, so as to reduce the water resistance in the water outlet channel 1222a.

[0107] As shown in Figure 11 and Figure 13 The water inlet valve body 1a further has a first water supplement channel 1211a independent of the water inlet channel 1221a, one end of the first water supplement channel 1211a is in communication with the water inlet interface 111a, and the other end of the first water supplement channel 1211a is in communication with the water outlet channel 1222a when the first flow regulating assembly 2a opens the passage between the water inlet channel 1221a and the water outlet channel 1222a. Specifically, the other end of the first water supplement channel 1211a can be in communication with the water outlet channel 1222a through a first communication port 1251a. By arranging the first water supplement channel 1211a, the water inlet flow at the same node can be increased, thereby improving the regulation efficiency of the water inlet flow.

[0108] Specifically, the external cold water flows into the water inlet interface 111a and is divided into two paths, one of which flows to the first water supplement channel 1211a, and the other of which flows to the water inlet channel 1221a. When the first blocking part 2121a is attached to the first communication port 1251a, the water in the first water supplement channel 1211a and the water inlet channel 1221a cannot flow into the water outlet channel 1222a through the first communication port 1251a; when the servo motor 21a is started to drive the first blocking part 2121a away from the first communication port 1251a, the cold water in the first water supplement channel 1211a and the cold water in the water inlet channel 1221a can be combined in the water outlet channel 1222a through the first communication port 1251a, and then flow into the water supply channel 320 of the heat exchange structure 300 through the second heat exchange inlet channel 112a, and exchange heat with the hot water in the heat exchange channel 310 of the heat exchange structure 300 to form warm water, and then flow to the water outlet valve 100b, and finally flow to the bathroom system from the outlet of the bathroom channel 133b of the water outlet valve 100b to provide users with domestic water. When the external temperature is high, the cold water flowing into the water inlet interface 111a has a high temperature, and the same amount of gas is sufficient to heat the water to a very high temperature. At this time, the servo motor 21a can drive the first blocking part 2121a to move away from the first communication port 1251a, so as to increase the distance between the first blocking part 2121a and the first communication port 1251a, thereby increasing the water inlet flow rate between the first water supplement channel 1211a and the water outlet channel 1222a and between the water inlet channel 1221a and the water outlet channel 1222a, so as to reduce the temperature of the warm water after heat exchange by increasing the flow rate of the cold water, thereby avoiding that the temperature of the warm water after heat exchange is too high to scald the user.

[0109] Optionally, the cross-sectional area of the first water supplement channel 1211a is S0, the cross-sectional area of the water inlet channel 1221a is S1, and the cross-sectional area of the water outlet channel 1222a is S2, wherein (S0+S1) / S2<1. That is, the sum of the water flow path of the first water supplement channel 1211a and the water flow path of the water inlet channel 1221a is less than the water flow path of the water outlet channel 1222a, which can further reduce the water resistance in the water outlet channel 1222a.

[0110] Continue as Figures 11-14As shown, the second valve body 12a further comprises a water supplement branch pipe 121a which is arranged in parallel with the water inlet and outlet branch pipe 122a, and the first valve body 11a is further provided with a water supplement interface 115a, the water supplement branch pipe 121a is inserted into the water supplement interface 115a and connected with the water inlet cavity 1171a, and the first water supplement channel 1211a is arranged in the water supplement branch pipe 121a. Optionally, the second valve body 12a further comprises a main valve part 125a, and the water supplement branch pipe 121a and the water inlet and outlet branch pipe 122a are connected to the main valve part 125a, and the first flow adjusting assembly 2a is installed on the main valve part 125a. By arranging the main valve part 125a, the overall support of the water supplement branch pipe 121a and the water inlet and outlet branch pipe 122a can be realized to ensure the integrity of the second valve body 12a.

[0111] As shown in Figure 10 , Figure 11 and Figure 13 , the water inlet valve 100a further comprises a manual water supplement valve 3a, and the water inlet valve body 1a further has a second water supplement channel 1241a and a second communication port 1240a, one end of the second water supplement channel 1241a can be connected with the first water supplement channel 1211a through the second communication port 1240a, and the other end of the second water supplement channel 1241a is connected with the water pump interface 114a; the manual water supplement valve 3a is adjustably installed on the water inlet valve body 1a and can selectively block the second communication port 1240a. When the heating water circuit is short of water, the manual water supplement valve 3a can be adjusted to open the second communication port 1240a, so that the water in the first water supplement channel 1211a flows to the second water supplement channel 1241a through the second communication port 1240a and then flows to the water pump interface 114a to be delivered to the combustion chamber 200 by the water pump for heating to supplement the heating water circuit. The specific structure and working principle of the manual water supplement valve 3a are not limited in the embodiment, and the manual water supplement valve which can be applied to the water inlet valve in the prior art is within the protection scope of the embodiment.

[0112] Specifically, the second valve body 12a further comprises an outer ring branch pipe 124a which is arranged around the outer periphery of the water supplement branch pipe 121a, and the space between the two forms the second water supplement channel 1241a.

[0113] Optionally, the second valve body 12a further comprises a mounting branch pipe 123a which is connected to the main valve part 125a, and the mounting branch pipe 123a is provided with a mounting cavity, and the manual water supplement valve 3a is partially installed in the mounting cavity to realize stable installation of the manual water supplement valve 3a.

[0114] Figure 15 A cross-sectional structure schematic diagram of the first flow adjusting assembly 2a provided by the embodiment is shown. As shown in Figure 15 and in combination with Figures 11-13As shown, the servo motor 21a comprises a motor body 211a and a regulating valve core 212a connected with the motor body 211a, and the outer periphery of the regulating valve core 212a is outwardly convex to form the first blocking part 2121a. Further, the water inlet valve body 1a is further provided with a first mounting port 1253a for mounting the first flow regulating assembly 2a, and the first flow regulating assembly 2a further comprises a support sleeve 22a which is sealingly connected to the first mounting port 1253a, and the regulating valve core 212a is arranged in the support sleeve 22a and is threadedly connected with the support sleeve 22a. When the motor body 211a is started, it can drive the regulating valve core 212a to rotate, thereby driving the first blocking part 2121a to move along the axis direction of the regulating valve core 212a to approach or move away from the first communication port 1251a. By arranging the support sleeve 22a, the transmission support of the regulating valve core 212a can be increased. In the embodiment, the first mounting port 1253a is arranged at the end of the main valve part 125a away from the water replenishing branch pipe 121a, and the first communication port 1251a is a sealing step convexly arranged on the inner wall of the first mounting port 1253a.

[0115] Specifically, the support sleeve 22a comprises a transmission matching part 221a and an inner sealing part 222a connected with each other, the transmission matching part 221a is threadedly matched with the regulating valve core 212a, and the inner sealing part 222a is sleeved on the outer periphery of the regulating valve core 212a, and a first sealing member 231a is arranged between the inner sealing part 222a and the regulating valve core 212a, so as to ensure the sealing performance of the transmission part of the regulating valve core 212a and the water flowing area in the water inlet valve body 1a. Optionally, a second sealing member 232a is further arranged between the transmission matching part 221a and the first mounting port 1253a, so as to enhance the sealing performance of the servo motor 21a and the water flowing area in the water inlet valve body 1a, thereby protecting the power element. In the embodiment, the first sealing member 231a and the second sealing member 232a can both be O-shaped sealing rings, and the number of layers of the O-shaped sealing rings is not limited; for example, the first sealing member 231a can be arranged in one layer, two layers, three layers or even more layers.

[0116] It should be explained that when the first blocking part 2121a is located at the second position, the first blocking part 2121a abuts against the support sleeve 22a, so as to limit the maximum opening degree of the first blocking part 2121a by the position of the support sleeve 22a, thereby facilitating the determination of the maximum value of the water flow. When designing the water inlet valve 100a, the maximum opening degree of the first blocking part 2121a can be changed by changing the length of the part of the support sleeve 22a for abutting against the first blocking part 2121a, thereby changing the regulating range of the water flow.

[0117] Optionally, the water inlet valve body 1a (specifically the main valve part 125a) is further provided with a guide groove 1252a, and the one end of the adjusting valve core 212a away from the motor body 211a is slidably arranged in the guide groove 1252a. When the motor body 211a drives the adjusting valve core 212a to move, the adjusting valve core 212a can be guided and limited by the guide groove 1252a, so as to ensure the stability of the adjusting valve core 212a during movement.

[0118] Figure 16 The structural schematic diagram of the water inlet valve 100a provided by the embodiment is shown in another view. As shown in Figure 16 and combined with Figure 11 , the water outlet channel 1222a and the second heat exchange inlet channel 112a are provided with a flow detection assembly. The flow detection assembly includes an impeller 41a and a flow sensor 42a, and the first valve body 11a of the water inlet valve body 1a is provided with an impeller cavity 118a. The impeller cavity 118a is in communication with the water outlet channel 1222a through a water outlet cavity 1172a, and the impeller cavity 118a is also in communication with the second heat exchange inlet channel 112a. The impeller 41a is arranged in the impeller cavity 118a, and the flow sensor 42a is signal connected with the impeller 41a. Combined with Figure 11 , the water flows out of the water outlet channel 1222a, enters the impeller cavity 118a through the water outlet cavity 1172a, and rotates the impeller 41a by impacting the blades of the impeller 41a, so that the flow sensor 42a outputs a water flow signal, so as to detect the water flow entering the second heat exchange inlet channel 112a, facilitate accurate control of the flow, and finally the water flows into the heat exchange structure 300 through the outlet of the second heat exchange inlet channel 112a.

[0119] In the related art, the water temperature of the water flowing out of the outlet of the sanitary channel 133b of the water outlet valve 100b can only be adjusted by the heat exchange efficiency of the heat exchange structure 300 and the initial temperature of the water flowing into the water supply channel 320 of the heat exchange structure 300, so that the temperature of the water flowing out of the outlet of the sanitary channel 133b of the water outlet valve 100b is relatively high, which affects the user's water experience.

[0120] Figure 17 The structural schematic diagram of the second flow adjusting assembly 6b provided by the embodiment is shown. In order to solve the above problems, as shown in Figure 17 and combined with Figure 1 , Figure 4 , Figure 7 , Figure 10 , Figure 11As shown, in the present embodiment, the water outlet valve 100b further comprises a second flow adjusting assembly 6b, and the water inlet valve body 1a further has a water outlet interface 119a in communication with the water outlet channel 1222a; the water outlet valve body 1b further has a cold water flow channel 136b in communication with the bathroom channel 133b; the wall-hanging stove waterway system further comprises a water temperature adjusting pipeline 402, two ends of the water temperature adjusting pipeline 402 being in communication with the water outlet interface 119a and the cold water flow channel 136b respectively; the second flow adjusting assembly 6b comprises an adjusting member 61b movably arranged in the water outlet valve body 1b, and the flow of cold water in the cold water flow channel 136b can be adjusted by adjusting the relative position between the adjusting member 61b and the water outlet valve body 1b. With such an arrangement, when the first communication port 1251a is opened, the water in the water inlet interface 111a can flow into the cold water flow channel 136b through the first water supplement channel 1211a and / or the water inlet channel 1221a, the first communication port 1251a, the water outlet channel 1222a, the water outlet interface 119a and the water temperature adjusting pipeline 402 in sequence, the second flow adjusting assembly 6b adjusts the amount of cold water flowing from the cold water flow channel 136b to the bathroom channel 133b according to the user's demand, and mixes the cold water with the hot water flowing from the water supply channel 320 of the heat exchange structure 300 to the first heat exchange outflow channel 132b, and finally flows out from the bathroom channel 133b, so as to adjust the water temperature at the outlet of the bathroom channel 133b and avoid the situation that the hot water flowing out from the bathroom channel 133b is too high in temperature, thereby improving the user's water experience.

[0121] Optionally, the water outlet valve body 1b further has a mixing chamber 137b located between and in communication with the first heat exchange outflow channel 132b and the cold water flow channel 136b, and the outlet of the mixing chamber 137b is in communication with the bathroom channel 133b, so that the cold water flowing into the cold water flow channel 136b and the hot water flowing into the first heat exchange outflow channel 132b can be mixed in the mixing chamber 137b and then flow into the bathroom channel 133b. By arranging the mixing chamber 137b, the cold water flowing into the cold water flow channel 136b and the hot water flowing into the first heat exchange outflow channel 132b can be mixed in the mixing chamber 137b, so as to increase the mixing space of the cold water and the hot water and ensure that the cold water and the hot water can be fully mixed before flowing out from the outlet of the bathroom channel 133b, thereby improving the uniformity of the mixing of the cold water and the hot water.

[0122] In the embodiment, the cold water flowing into the cold water flow channel 136b and the hot water flowing into the first heat exchange outflow channel 132b both flow into the mixing chamber 137b first for mixing. To improve the mixing effect of the two, the inner wall of the mixing chamber 137b towards the cold water flow channel 136b is arc-shaped. When the cold water in the cold water flow channel 136b flows into the mixing chamber 137b, it can rotate in the arc-shaped inner wall of the mixing chamber 137b, playing a mixing and stirring role, thereby achieving the effect of sufficient mixing of the cold water and the hot water. Of course, in other embodiments, the inner wall of the mixing chamber 137b towards the first heat exchange outflow channel 132b can also be arc-shaped, which can also achieve the above-mentioned effect.

[0123] Optionally, the axis direction of the mixing chamber 137b is arranged at an angle with the axis direction of the bathroom channel 133b. This design can make the axis direction of the mixing chamber 137b inclined relative to the horizontal plane, so as to increase the flow path of the mixed water before entering the bathroom channel 133b, and at the same time, increase the mixing time of the cold water and the hot water, thereby further ensuring that the two can be fully mixed. Optionally, the angle α between the axis direction of the mixing chamber 137b and the axis direction of the bathroom channel 133b is 5°-45°. For example, the angle α between the axis direction of the mixing chamber 137b and the axis direction of the bathroom channel 133b can be 10°, 12°, 15°, 18°, 20°, 25°, 28°, 30°, 32°, 35°, 38°, 40°, 42°, etc., and the designer can adjust the specific value of α according to actual needs.

[0124] Optionally, the axis direction of the first heat exchange outflow channel 132b is arranged at an angle with the axis direction of the cold water flow channel 136b. This design can make the cold water in the cold water flow channel 136b flow into the mixing chamber 137b from one side of the mixing chamber 137b, and the hot water in the first heat exchange outflow channel 132b flow into the mixing chamber 137b from the other side of the mixing chamber 137b, and collide, thereby achieving a better water mixing effect. In the embodiment, the angle between the axis direction of the first heat exchange outflow channel 132b and the axis direction of the cold water flow channel 136b is 90°, which can achieve the maximum impact effect of the cold water on the hot water in the bathroom channel 133b, thereby achieving the best water mixing effect. Of course, in other embodiments, the angle between the axis direction of the first heat exchange outflow channel 132b and the axis direction of the cold water flow channel 136b can also be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0125] Figure 18 Part of the structure of the water outlet valve body 1b provided in the embodiment is shown. As shown in FIG. 1b, the water outlet valve body 1b comprises a first heat exchange outflow channel 132b and a cold water flow channel 136b. The first heat exchange outflow channel 132b and the cold water flow channel 136b are connected to each other through a mixing chamber 137b. The first heat exchange outflow channel 132b is connected to a bathroom channel 133b, and the cold water flow channel 136b is connected to a cold water inlet channel 134b. Figure 18 In combination with Figure 7 , Figure 17As shown, the outlet valve body 1b further has a fourth communication port 138b capable of communicating the cold water flow channel 136b and the mixing chamber 137b, and the second flow adjusting assembly 6b further comprises an adjusting driving member 62b arranged on the outlet valve body 1b, the adjusting member 61b comprises an adjusting rod 611b and a second blocking portion 612b sleeved on the adjusting rod 611b, one end of the adjusting rod 611b is threadedly connected to the outlet valve body 1b, the other end penetrates through the outlet valve body 1b and is connected to an output end of the adjusting driving member 62b, and can rotate under the driving action of the adjusting driving member 62b, so as to make the second blocking portion 612b close to or away from the fourth communication port 138b, thereby realizing the adjustment of the size of the passage between the cold water flow channel 136b and the mixing chamber 137b, which is simple in structure and convenient for assembly and adjustment. When the temperature of the hot water in the first heat exchange outflow channel 132b is relatively low, the adjusting driving member 62b can be started to drive the adjusting rod 611b to rotate, thereby driving the second blocking portion 612b to move to a position abutting against the fourth communication port 138b, so as to stop the supply of cold water into the cold water flow channel 136b; the flow passage between the cold water flow channel 136b and the mixing chamber 137b can also be adjusted by adjusting the distance between the second blocking portion 612b and the fourth communication port 138b, so that the cold water and the hot water are mixed in the mixing chamber 137b at a suitable ratio. The flow passage between the cold water flow channel 136b and the mixing chamber 137b refers to the channel for the flow of cold water between the cold water flow channel 136b and the mixing chamber 137b, and the greater the flow passage, the greater the flow of cold water into the cold water flow channel 136b. In the embodiment, the adjusting driving member 62b can be a driving motor with a rotary driving function.

[0126] It should be noted that the specific structure of the adjusting member 61b is not limited in the embodiment, and the adjusting member 61b can also be other adjusting members capable of blocking the fourth communication port 138b, and the specific structure of the adjusting driving member 62b is also not limited in the embodiment, and the adjusting driving member 62b can be selected according to the specific structure of the adjusting member 61b.

[0127] As Figure 10 , Figure 11 and Figure 16As shown, the water inlet valve 100a further comprises a circulating water pump 6a, and the first valve body 11a of the water inlet valve body 1a is further provided with a second mounting port 110a, which is located between the second heat exchange inlet channel 112a and the water outlet interface 119a, and the circulating water pump 6a is mounted in the second mounting port 110a. The circulating water pump 6a can pump the water in the bathroom channel 133b of the water outlet valve 100b into the water outlet interface 119a, and then flow into the water supply channel 320 of the heat exchange structure 300 through the second heat exchange inlet channel 112a to be re-heated. The water after heat exchange flows out to the bathroom channel 133b of the water outlet valve 100b, so as to avoid that the water temperature in the bathroom channel 133b is too low when the user re-opens the bathroom channel 133b after closing it, which affects the user experience. By integrating the circulating water pump 6a on the water inlet valve 100a, the overall structure of the water inlet valve 100a is compact, the integration degree is high, and the zero-cold-water function of the water outlet valve 100b can be realized, further improving the user experience.

[0128] Specifically, when the circulating water pump 6a is started, it can make the water in the bathroom channel 133b of the water outlet valve 100b flow into the water supply channel 320 of the heat exchange structure 300 through the cold water channel 136b, the water temperature adjusting pipeline 402, the water outlet interface 119a, and the second heat exchange inlet channel 112a in sequence; at the same time, the first flow regulating assembly 2a can also adjust the water flow curve in the water outlet channel 1222a to cooperate with the circulating water pump 6a, so as to adjust the output power of the circulating water pump 6a to the best state.

[0129] In order to accurately adjust the water temperature of the domestic water flowing out from the outlet of the bathroom channel 133b, as shown in Figure 1 and Figure 7 As shown, the water outlet valve 100b further comprises a first temperature detection member 71b mounted on the water outlet valve body 1b and used for detecting the temperature of the mixed water in the bathroom channel 133b, and the first temperature detection member 71b is electrically connected with the first flow regulating assembly 2a and / or the second flow regulating assembly 6b. By arranging the first temperature detection member 71b, the adjusting driving member 62b can adjust the spacing between the second blocking part 612b and the fourth communication port 138b according to the temperature of the mixed water detected by the first temperature detection member 71b, that is, adjust the flow of cold water flowing into the cold water channel 136b, and then realize the accurate control of the water temperature of the mixed water in the bathroom channel 133b; in addition, when the spacing between the second blocking part 612b and the fourth communication port 138b has reached the maximum, but the temperature of the mixed water in the bathroom channel 133b is still high, the first flow regulating assembly 2a is started to adjust the spacing between the first blocking part 2121a and the first communication port 1251a, so as to increase the water flow in the water outlet channel 1222a.

[0130] Optionally, the first temperature detecting member 71b is arranged at a position close to the outlet of the bathroom passage 133b, so that the first temperature detecting member 71b obtains the temperature of the mixed water after the cold water and the hot water are fully mixed. The present embodiment does not limit the specific position of the first temperature detecting member 71b arranged in the bathroom passage 133b, and the designer can adjust the position according to the actual situation.

[0131] To further realize the accurate adjustment of the water temperature of the domestic water flowing out of the outlet of the bathroom passage 133b, the outlet valve 100b further comprises a second temperature detecting member 72b, which is installed on the outlet valve body 1b and is used for detecting the temperature of the hot water in the first heat exchange outlet channel 132b. The second temperature detecting member 72b is electrically connected with the first flow adjusting assembly 2a and / or the second flow adjusting assembly 6b. By arranging the second temperature detecting member 72b, the adjusting driving member 62b can adjust the distance between the second blocking part 612b and the fourth communication port 138b according to the temperature of the mixed water detected by the second temperature detecting member 72b, that is, adjust the flow of the cold water flowing into the cold water channel 136b, so as to realize the accurate control of the water temperature of the mixed water in the bathroom passage 133b. In addition, when the temperature of the hot water in the first heat exchange outlet channel 132b is very high and the distance between the second blocking part 612b and the fourth communication port 138b has reached the maximum, the first flow adjusting assembly 2a can also be started to adjust the distance between the first blocking part 2121a and the first communication port 1251a, so as to increase the water flow in the outlet passage 1222a.

[0132] Optionally, as shown in Figure 1 、 Figure 4 、 Figure 7 and Figure 16 , the inlet valve 100a further comprises a third temperature detecting member 5a, which is installed on the inlet valve body 1a and is used for detecting the temperature of the cold water in the outlet passage 1222a. The third temperature detecting member 5a is electrically connected with the first flow adjusting assembly 2a and / or the second flow adjusting assembly 6b. It can be understood that the temperature of the cold water flowing into the inlet interface 111a will change with the change of the ambient temperature. By arranging the third temperature detecting member 5a, the temperature of the cold water flowing into the cold water channel 136b can be accurately detected, so as to further accurately adjust the water temperature of the domestic water flowing out of the outlet of the bathroom passage 133b.

[0133] In other words, the third temperature detecting member 5a is equivalent to detecting the temperature of the cold water flowing into the cold water flow channel 136b, the second temperature detecting member 72b is used to detect the temperature of the hot water in the first heat exchange outflow channel 132b, the first temperature detecting member 71b is used to detect the temperature of the mixed water in the bathroom channel 133b, and the second flow adjusting assembly 6b can comprehensively adjust the spacing between the second blocking part 612b and the fourth communication opening 138b according to the detection results of the first temperature detecting member 71b, the second temperature detecting member 72b and the third temperature detecting member 5a; when the spacing between the second blocking part 612b and the fourth communication opening 138b has reached the maximum, but the temperature of the mixed water in the bathroom channel 133b is still high, the first flow adjusting assembly 2a can be started to adjust the spacing between the first blocking part 2121a and the first communication opening 1251a, so as to increase the water flow in the water outlet channel 1222a, and then the water temperature of the mixed water in the bathroom channel 133b can be accurately adjusted.

[0134] In the embodiment, the first temperature detecting member 71b, the second temperature detecting member 72b and the third temperature detecting member 5a are all NTCs. Of course, in other embodiments, the first temperature detecting member 71b, the second temperature detecting member 72b and the third temperature detecting member 5a can also be other temperature sensors such as thermocouples, thermal resistors and the like, and the types of the first temperature detecting member 71b, the second temperature detecting member 72b and the third temperature detecting member 5a can be the same or different.
