The heat exchange structure includes a heat exchange channel and a water supply channel for heat exchange. The water outlet valve includes a three-way valve part and a second valve part that are connected to each other. A heating water outlet interface is provided at one end of the three-way valve part, and a heating water inlet interface is provided at the water inlet valve. The heating water inlet interface is connected to the combustion chamber through a water pump. Part of the water coming out of the combustion chamber enters the heat exchange channel of the heat exchange structure through the water outlet valve, and the other part of the water enters the water outlet valve and flows out from the heating water outlet interface of the water outlet valve to provide users with hot water for heating.

In addition, the water inlet valve also includes a domestic water inlet interface, which is connected to an external water source to provide water to the water supply channel of the heat exchange structure. After the water in the water supply channel undergoes heat exchange with the heat exchange channel, it can flow into the water outlet valve and flow out from the domestic water outlet interface of the water outlet valve to provide users with hot water for home bathing, kitchen, etc. However, in the related art, the water temperature of the water flowing out from the domestic water outlet interface of the water outlet valve can only be adjusted by the heat exchange efficiency of the heat exchange structure and the initial temperature of the water flowing into the water supply channel of the heat exchange structure, resulting in a higher temperature of the water flowing out from the domestic water outlet interface of the water outlet valve, which affects the user's water use experience.

[0054] Figure 1 The schematic diagram of the structure of the water outlet valve provided by the utility model is shown in one viewing angle. Figure 1 As shown, the utility model provides a water circuit component system, which includes a combustion chamber (not shown in the figure), a heat exchange structure (not shown in the figure), a water inlet valve (not shown in the figure) and a water outlet valve, wherein the heat exchange structure includes a heat exchange channel and a water supply channel for heat exchange; the water outlet valve includes a valve body 1, and the valve body 1 is provided with a non-connected heating channel 10 and a bathroom channel 20, the inlet of the heating channel 10 is connected to the combustion chamber, and the valve body 1 is also provided with a heat exchange water inlet channel 121 connected to the heating channel 10 and a heat exchange water outlet channel 131 connected to the bathroom channel 20, the heat exchange water inlet channel 121 is connected to the inlet of the heat exchange channel of the heat exchange structure, and the outlet of the heat exchange channel is connected to the combustion chamber through the water inlet valve; the water inlet valve can also supply water to the water supply channel, and the outlet of the water supply channel is connected to the heat exchange water outlet channel 131. That is to say, the hot water heated by the combustion chamber can enter the heat exchange channel of the heat exchange structure through the heating channel 10, and after exchanging heat with the water in the water supply channel, it flows into the combustion chamber through the water inlet valve to form a heat exchange circulation loop; the water that enters the water supply channel of the heat exchange structure through the water inlet valve and undergoes heat exchange with the water in the heat exchange channel to form hot water, which can flow into the bathroom channel 20 through the heat exchange water outlet channel 131, and the water flowing out from the outlet of the bathroom channel 20 can supply the user's domestic water needs.

[0055] However, in the prior art, the water temperature of the water flowing out of the outlet of the bathroom channel can only be adjusted by the heat exchange efficiency of the heat exchange structure and the initial temperature of the water flowing into the water supply channel of the heat exchange structure, resulting in a higher temperature of the water flowing out of the outlet of the bathroom channel of the water outlet valve, which affects the user's water use experience. In order to solve the above problem, the utility model also provides a water outlet valve, which can adjust the temperature of the hot water flowing out of the outlet of the bathroom channel 20 for use in the user's home bathing, kitchen and other places, so as to improve the user's water use experience. The specific structure of the water outlet valve provided by the utility model is introduced below through multiple embodiments.

[0056] Embodiment 1

[0057] Figure 2 FIG. 2 shows a schematic cross-sectional view of the water outlet valve provided in this embodiment. Figure 2 Combined with Figure 1 As shown, the outlet valve includes a valve body 1 and an adjusting component 2. The valve body 1 has a bathroom channel 20 and a heat exchange outlet flow channel 131 and a cold water flow channel 132 both connected to the bathroom channel 20. The heat exchange outlet flow channel 131 is connected to the hot water outlet of the heat exchange structure, and the cold water flow channel 132 is connected to an external water source. The cold water flowing into the cold water flow channel 132 and the hot water flowing into the heat exchange outlet flow channel 131 can flow out from the outlet of the bathroom channel 20 after mixing; the adjusting component 2 includes an adjusting member 21 movably arranged in the valve body 1, and the flow rate of cold water in the cold water flow channel 132 can be adjusted by adjusting the relative position of the adjusting member 21 and the valve body 1. It should be explained that the hot water outlet of the heat exchange structure is the outlet of the above-mentioned water supply channel.

[0058] The outlet valve provided in this embodiment, by setting a cold water flow channel 132 connected to the bathroom channel 20 on the valve body 1, the cold water in the external water source can enter the valve body 1 through the cold water flow channel 132, and mix with the hot water flowing into the heat exchange outlet flow channel 131 and then flow out from the outlet of the bathroom channel 20, thereby adjusting the temperature of the hot water flowing out of the bathroom channel 20 for the user's home bathing, kitchen and other places; by setting an adjusting member 21 that can move relative to the valve body 1 in the valve body 1, when the adjusting member 21 moves relative to the valve body 1, the flow of cold water flowing into the cold water flow channel 132 can be adjusted to adjust the temperature of the hot water flowing out of the bathroom channel 20 for the user's home bathing, kitchen and other places to a set comfortable temperature. The above-mentioned setting structure is simple, easy to adjust, and can improve the user's water experience.

[0059] In this embodiment, the regulating member 21 is a rotating valve core rotatably disposed in the cold water flow channel 132. The rotating valve core can be rotated to adjust the size of the flow path between the cold water flow channel 132 and the bathroom channel 20, so that the cold water and the hot water are mixed in a suitable ratio, thereby ensuring that the domestic water flowing out of the bathroom channel 20 has a suitable water temperature. It should be explained that the flow path between the cold water flow channel 132 and the bathroom channel 20 refers to the channel between the cold water flow channel 132 and the bathroom channel 20 for the cold water to flow. The larger the flow path, the greater the flow rate of the cold water flowing into the cold water flow channel 132.

[0060] Optionally, the rotating valve core is a cylindrical structure or a semi-cylindrical structure to facilitate its rotation in the valve body 1 and ensure that the arc-shaped surface of the rotating valve core is always in contact with the inner wall of the cold water channel 132 close to the bathroom channel 20 during rotation, so as to avoid the cold water flowing into the cold water channel 132 from flowing out directly from the outlet of the bathroom channel 20 without mixing with the hot water.

[0061] In order to realize the rotation of the rotating valve core, the regulating assembly 2 also includes an adjusting driving member 22, which is arranged on the valve body 1, and the output end of the adjusting driving member 22 is connected to the rotating valve core to drive the rotating valve core to rotate. In this embodiment, the adjusting driving member 22 is a servo motor, that is, the regulating assembly 2 is a servo regulating valve, and the valve core of the servo regulating valve forms the above-mentioned regulating member 21. The servo regulating valve is a relatively mature technology in the prior art, and the specific structure of the servo regulating valve is not repeated in this embodiment.

[0062] Figure 3 FIG. 2 shows a schematic diagram of the structure of the water outlet valve provided in this embodiment from another perspective. Figure 3 Combined with Figure 2 As shown, in order to accurately adjust the water temperature of domestic water flowing out of the outlet of the bathroom channel 20, the water outlet valve also includes a first temperature detection member 31, which is arranged in the bathroom channel 20, and the first temperature detection member 31 is used to detect the temperature of the mixed water in the bathroom channel 20, and the first temperature detection member 31 is electrically connected to the adjustment component 2. With this arrangement, the adjustment component 2 can adjust the relative position of the adjustment member 21 relative to the valve body 1 according to the mixed water temperature detected by the first temperature detection member 31, that is, adjust the flow rate of cold water flowing into the cold water flow channel 132, thereby achieving accurate adjustment of the water temperature of the mixed water in the bathroom channel 20. In this embodiment, the first temperature detection member 31 is a thermistor (NTC). Of course, in other embodiments, the first temperature detection member 31 can also be other temperature sensors such as thermocouples, thermal resistors, etc.

[0063] It should be noted that, in this embodiment, the cold water flowing into the valve body 1 through the cold water flow channel 132 and the hot water flowing into the valve body 1 through the heat exchange outlet flow channel 131 are in contact at the inlet of the bathroom channel 20, and are fully mixed in the process of flowing in the bathroom channel 20, and then flow out from the outlet of the bathroom channel 20. In order to ensure the accuracy of the water temperature value of the mixed water obtained by the first temperature detection component 31, the first temperature detection component 31 is set at a position close to the outlet of the bathroom channel 20, so that the first temperature detection component 31 obtains the water temperature of the mixed water after the cold water and the hot water are fully mixed. This embodiment does not limit the specific position of the first temperature detection component 31 in the bathroom channel 20, and the designer can adjust its setting position according to actual conditions.

[0064] In order to further realize the accurate regulation of the water temperature of the domestic water flowing out from the outlet of the bathroom channel 20, the water outlet valve also includes a second temperature detection member 32, which is arranged in the heat exchange outlet flow channel 131, and the second temperature detection member 32 is used to detect the temperature of the hot water in the heat exchange outlet flow channel 131, and the second temperature detection member 32 is electrically connected to the adjustment component 2. By setting the second temperature detection member 32, the temperature of the hot water flowing into the heat exchange outlet flow channel 131 can be detected, and the adjustment component 2 can adjust the relative position of the adjustment member 21 relative to the valve body 1 by combining the detection results of the first temperature detection member 31 and the second temperature detection member 32, that is, adjust the flow rate of the cold water flowing into the cold water flow channel 132, and further improve the accuracy of the water temperature regulation of the mixed water in the bathroom channel 20. In this embodiment, the second temperature detection member 32 is a thermistor (NTC). Of course, in other embodiments, the second temperature detection member 32 can also be other temperature sensors such as thermocouples, thermal resistors, etc.

[0065] like Figure 1 and Figure 2 As shown, the axial direction of the heat exchange outlet flow channel 131 and the axial direction of the cold water flow channel 132 are set at an angle. With this setting, the cold water flowing into the bathroom channel 20 from the cold water flow channel 132 can impact the hot water in the bathroom channel 20 from one side of the axial direction of the heat exchange outlet flow channel 131, thereby achieving a better water mixing effect. In this embodiment, the angle between the axial direction of the heat exchange outlet flow channel 131 and the axial direction of the cold water flow channel 132 is 90°. This design can achieve the maximum impact effect of cold water on the hot water in the bathroom channel 20 to achieve the best water mixing effect. Of course, in other embodiments, the angle between the axial direction of the heat exchange outlet flow channel 131 and the axial direction of the cold water flow channel 132 can also be set to 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0066] In order to improve the mixing effect of cold water and hot water in the bathroom channel 20, in this embodiment, the inner wall of the bathroom channel 20 facing the cold water flow channel 132 is arranged in an arc shape. When the cold water in the cold water flow channel 132 flows into the bathroom channel 20, it can rotate within the arc-shaped inner wall of the bathroom channel 20 to play a mixing and stirring role, thereby achieving the effect of fully mixing the cold water and hot water.

[0067] Continue as Figure 1-Figure 2 As shown, the valve body 1 includes a three-way valve portion 11, a first valve portion 12 and a second valve portion 13. The first valve portion 12 and the second valve portion 13 are both formed on one side of the three-way valve portion 11 and are arranged at intervals along the axial direction of the three-way valve portion 11. The heat exchange water inlet channel 121 is opened on the first valve portion 12; a heating channel 10 is opened in the three-way valve portion 11 and the first valve portion 12, and the inlet of the heating channel 10 is connected to the burner; the bathroom channel 20 is opened in the second valve portion 13, and the side wall of the second valve portion 13 is provided with the above-mentioned cold water channel 132 and heat exchange water outlet channel 131. The first valve portion 12 and the second valve portion 13 are arranged on the same side of the three-way valve portion 11, which can facilitate the installation of the heat exchange structure.

[0068] Figure 4 FIG. 2 shows a schematic diagram of the structure of the water outlet valve provided in this embodiment from another perspective. Figure 4 Combined with Figure 1 and Figure 2 As shown, the heating channel 10 includes a valve cavity 101 disposed in the three-way valve portion 11 and a hot water outlet channel 102 disposed in the first valve portion 12. The three-way valve portion 11 is also provided with an inlet interface 111 and a heating outlet interface 112. The inlet interface 111 is in communication with the valve cavity 101 and is connected to the combustion chamber, and the heating outlet interface 112 can supply the water in the valve cavity 101 to the household heating equipment. Among them, the inlet interface 111 is disposed opposite to the heat exchange inlet channel 121 and the heat exchange outlet channel 131, so that the inlet interface 111 is not blocked by the heat exchange structure when connected to the combustion chamber through a pipeline. It should be noted that the inlet of the above-mentioned heating channel 10 is the inlet interface 111.

[0069] Figure 5 FIG. 4 is a schematic diagram showing the structure of the valve core assembly 4 provided in this embodiment. Figure 5 Combined with Figure 2As shown, the water outlet valve also includes a valve core assembly 4, which is arranged in the valve cavity 101. A separation sleeve 113 is provided in the valve cavity 101. The valve core assembly 4 cooperates with the separation sleeve 113 to divide the valve cavity 101 into a first cavity 1011, a second cavity 1012 and a heating cavity 1013. The first cavity 1011 is connected to the inlet interface 111, the second cavity 1012 is connected to the hot water outlet channel 102, and the heating cavity 1013 is connected to the heating outlet interface 112. The valve core assembly 4 can cooperate with the separation sleeve 113 to selectively block the gap between the second cavity 1012 and the first cavity 1011 or the gap between the first cavity 1011 and the heating cavity 1013.

[0070] Specifically, the valve core assembly 4 includes a valve stem 41, a first sealing seat 42 and a second sealing seat 43, and the separation sleeve 113 includes a first portion 1131 and a second portion 1132. The first portion 1131 and the second portion 1132 are respectively sealed and connected to the inner wall of the valve cavity 101. The first portion 1131 is located between the first cavity 1011 and the second cavity 1012, and the second portion 1132 is located between the first cavity 1011 and the heating cavity 1013. The first sealing seat 42 can block the first portion 1131, and the second sealing seat 43 can block the second portion 1132. The valve stem 41 is sequentially inserted into the first sealing seat 42 and the second sealing seat 43, and the valve stem 41 can move along the axial direction of the three-way valve portion 11, thereby driving the first sealing seat 42 and the second sealing seat 43 to move along the axial direction of the three-way valve portion 11. When the valve stem 41 moves upward, the first sealing seat 42 blocks the first part 1131, and the second sealing seat 43 is spaced apart from the second part 1132. At this time, the inlet interface 111, the first cavity 1011, the heating cavity 1013 and the heating water outlet interface 112 are connected; when the valve stem 41 moves downward, the second sealing seat 43 blocks the second part 1132, and the first sealing seat 42 is spaced apart from the first part 1131. At this time, the inlet interface 111, the first cavity 1011, the second cavity 1012, the hot water outlet channel 102 and the heat exchange inlet channel 121 are connected, thereby realizing three-way switching.

[0071] Optionally, the outlet valve further includes a driving mechanism 5, which is disposed outside the three-way valve portion 11 and connected to the valve stem 41. The driving mechanism 5 can drive the valve core assembly 4 to reciprocate up and down. A first elastic member 61 is disposed between the first portion 1131 and the driving mechanism 5, and a second elastic member 62 is disposed between the second portion 1132 and the first portion 1131. The first elastic member 61 and the second elastic member 62 are both sleeved outside the valve stem 41 for resetting the valve core assembly 4. In this embodiment, the driving mechanism 5 is a synchronous motor. Of course, in other embodiments, according to different designs of the valve core assembly 4, the driving mechanism 5 can also be a stepping motor or other driving modules.

[0073] This embodiment provides a water outlet valve, the structure of which is substantially the same as that of the water outlet valve in the first embodiment, except that the structure of the valve body 1 is different.

[0074] Figure 6 A schematic structural diagram of the water outlet valve provided in this embodiment at one viewing angle is shown. Figure 7 FIG. 2 shows a cross-sectional schematic diagram of the water outlet valve provided in this embodiment. Specifically, Figure 6-Figure 7 As shown, a mixing chamber 30 is also provided in the valve body 1. The mixing chamber 30 is located between the heat exchange outlet flow channel 131 and the cold water flow channel 132 and is connected to both. The outlet of the mixing chamber 30 is connected to the bathroom channel 20. The cold water flowing into the cold water flow channel 132 and the hot water flowing into the heat exchange outlet flow channel 131 can be mixed in the mixing chamber 30. A sealing port 133 that can connect the cold water flow channel 132 and the mixing chamber 30 is also provided in the valve body 1. The adjustment member 21 can adjust the opening of the sealing port 133 by moving relative to the valve body 1. By providing the mixing chamber 30 in the valve body 1, the cold water flowing into the cold water flow channel 132 and the hot water flowing into the heat exchange outlet flow channel 131 can be mixed in the mixing chamber 30, so as to increase the mixing space of the cold water and the hot water, ensure that the cold water and the hot water can be fully mixed before flowing out from the outlet of the bathroom channel 20, and improve the uniformity of the mixing of the cold water and the hot water.

[0075] It should be noted that, in this embodiment, the cold water flowing into the cold water flow channel 132 and the hot water flowing into the heat exchange outlet water flow channel 131 both flow into the mixing chamber 30 for mixing first. To improve the mixing effect of the two, the inner wall of the mixing chamber 30 facing the cold water flow channel 132 is set in an arc shape. When the cold water in the cold water flow channel 132 flows into the mixing chamber 30, it can rotate in the arc-shaped inner wall of the mixing chamber 30 to play a mixing and stirring role, thereby achieving the effect of fully mixing the cold water and the hot water. Of course, in other embodiments, the inner wall of the mixing chamber 30 facing the heat exchange outlet water flow channel 131 can also be set in an arc shape, which can also achieve the above effect.

[0076] Optionally, in this embodiment, the distance between the setting position of the first temperature detection component 31 in the bathroom channel 20 and the mixing chamber 30 is greater than 5 mm, so as to ensure that the first temperature detection component 31 obtains the water temperature of the mixed water after the cold water and the hot water are fully mixed, thereby improving the accuracy of the detection result obtained by the first temperature detection component 31.

[0077] Figure 8 A schematic structural diagram of the water outlet valve provided in this embodiment from another perspective is shown. Fig. 9 Shows Figure 8 The cross-sectional view at AA. Figure 8-Figure 9As shown, in this embodiment, the adjusting member 21 is rotatably disposed at the sealing opening 133 , and when the adjusting driving member 22 is started, it can drive the adjusting member 21 to rotate to adjust the opening of the sealing opening 133 .

[0078] Continue as Figure 7 As shown, the axial direction of the mixing chamber 30 is set at an angle with the axial direction of the bathroom passage 20. This design can make the axial direction of the mixing chamber 30 tilt relative to the horizontal plane to increase the flow path of the mixed water entering the bathroom passage 20, while increasing the time for the cold water and hot water to mix, and further ensure that the two can be fully mixed. Optionally, the angle α between the axial direction of the mixing chamber 30 and the axial direction of the bathroom passage 20 is 5° to 45°. Exemplarily, the angle α between the axial direction of the mixing chamber 30 and the axial direction of the bathroom passage 20 can be set to 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.

[0079] Embodiment 3

[0080] This embodiment provides a water outlet valve, the structure of which is substantially the same as that of the water outlet valve in the second embodiment, except that the structure of the regulating component 2 is different.

[0081] Fig.10 A schematic structural diagram of the water outlet valve provided in this embodiment is shown. Fig.11 Shows Fig.10 A cross-sectional view at BB. Specifically, Figure 10-11 Combined with Figure 7 As shown, in this embodiment, the adjusting component 2 also includes an adjusting driving member 22 arranged on the valve body 1, and the adjusting member 21 includes an adjusting rod 211 and an adjusting valve core 212 sleeved on the adjusting rod 211. One end of the adjusting rod 211 is threadedly connected to the valve body 1, and the other end passes through the valve body 1 and is connected to the output end of the adjusting driving member 22, and can rotate under the driving action of the adjusting driving member 22 to make the adjusting valve core 212 approach or move away from the sealing port 133. The structure is simple and easy to assemble and adjust.

[0082] Optionally, the regulating rod 211 and the regulating valve core 212 are an integrated structure, which omits the steps of assembling multiple parts, saves assembly time, and improves assembly efficiency.

[0083] In this embodiment, a seal is also provided on the regulating valve core 212, and the seal also has the function of sealing the sealing port 133, so as to stop supplying cold water to the cold water channel 132 when the temperature of hot water in the heat exchange water outlet channel 131 is low, thereby further improving the user experience.

[0084] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
