[0041] Figure 1 A front view of the water outlet valve provided by the embodiment is shown. Figure 2A sectional view of the water outlet valve in one direction is shown. Figures 1-2 As shown in the figure, the water outlet valve provided by the embodiment is applied to a wall-hanging stove water system. The water outlet valve comprises a valve body 1, which has a three-way valve cavity 110, a heating passage 121, a heat exchange water inlet flow channel 131, a heat exchange water outlet flow channel (not shown in the figure) and a bathroom passage 132 in the valve body 1. The inlet of the three-way valve cavity 110 is connected to the hot water outlet of the combustion chamber of the wall-hanging stove water system, and the three-way valve cavity 110 can selectively communicate with the heating passage 121 or the heat exchange water inlet flow channel 131. The heat exchange water inlet flow channel 131 and the heat exchange water outlet flow channel are both used to connect the heat exchange structure of the wall-hanging stove water system. In operation, when the three-way valve cavity 110 is connected to the heating passage 121, the hot water in the combustion chamber can flow to the heating system through the three-way valve cavity 110 and the heating passage 121 in sequence, so as to provide heating demand for users. The water in the heating system, which is heat-exchanged with the outside, can flow to the combustion chamber through the water inlet valve of the wall-hanging stove water system to be heated again, so as to form a heating water circulation loop. When the three-way valve cavity 110 is connected to the heat exchange water inlet flow channel 131, the hot water in the combustion chamber can flow to the heat exchange passage of the heat exchange structure through the three-way valve cavity 110 and the heat exchange water inlet flow channel 131 in sequence, so as to exchange heat with the cold water in the water supply passage of the heat exchange structure. After heat exchange, the water in the heat exchange passage can flow to the combustion chamber through the water inlet valve to be heated again, so as to form a heat exchange circulation loop. In addition, after the cold water in the water supply passage exchanges heat with the hot water in the heat exchange passage, the cold water in the water supply passage forms warm water, which then flows to the bathroom system through the heat exchange water outlet flow channel and the bathroom passage 132 in sequence, so as to provide domestic water for users. The above is the prior art, and the embodiment will not be described in more detail.

[0042] The water outlet valve in the related art usually has a high installation height. To solve this problem, in the embodiment, the axis direction of the three-way valve cavity 110 is arranged at an angle with the axis direction of the heating passage 121. Compared with the scheme in the prior art in which the three-way valve cavity 110 and the heating passage 121 are coaxially arranged, the design can arrange the three-way valve cavity 110 and the heating passage 121 in two directions respectively, so as to avoid the case that the length of the valve body 1 along the axis direction of the three-way valve cavity 110 is too long, thereby optimizing the spatial layout of the entire water outlet valve, reducing the installation height of the wall-hanging stove water system, and meeting the miniaturization design requirement of the wall-hanging stove water system.

[0043] Figure 3 A sectional view of the water outlet valve in another direction is shown. Figure 3 and in combination with Figure 1 , Figure 2As shown, the valve body 1 includes a three-way valve part 11, a heating valve part 12, and a heat exchange valve part 13. The three-way valve part 11 is provided with the three-way valve cavity 110 described above, and the three-way valve cavity 110 extends along a first direction. The heating valve part 12 is connected to the three-way valve part 11, and the heating valve part 12 is provided with the heating passage 121 described above, which extends along a second direction. The heat exchange valve part 13 is connected to one side of the three-way valve part 11 and the heating valve part 12 along a third direction, and the heat exchange water inlet flow channel 131, the heat exchange water outlet flow channel, and the bathroom passage 132 are all provided in the heat exchange valve part 13. The first direction, the second direction, and the third direction are arranged at an angle with each other. This design can make the overall structure size of the valve body 1 be distributed in the three directions arranged at an angle with each other in the three-dimensional space, further avoid the length of the valve body 1 along the axis direction of the three-way valve cavity 110 being too long, and thus optimize the space layout of the entire water outlet valve.

[0044] As shown in Figure 1 and Figure 2 need to be explained. The height direction of the water outlet valve after actual installation is defined as the up-down direction. The side of the water outlet valve close to the combustion chamber is defined as up, the side of the water outlet valve away from the combustion chamber is defined as down, the side of the water outlet valve close to the heat exchange structure is defined as back, and the side of the water outlet valve away from the heat exchange structure is defined as front. When a user stands facing the front of the water outlet valve, the side of the water outlet valve facing the right hand of the user is defined as right, and the side of the water outlet valve facing the left hand of the user is defined as left. In addition, the height direction of the valve body 1 refers to the up-down direction, the width direction of the valve body 1 refers to the left-right direction, and the thickness direction of the valve body 1 refers to the front-back direction. In this embodiment, 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.

[0045] In other words, in this embodiment, the three-way valve part 11 extends along the front-back direction, the heating valve part 12 is connected to the lower part of the three-way valve part 11, and the heat exchange valve part 13 is connected to the right side of the three-way valve part 11 and the heating valve part 12, so that the entire valve body 1 has a substantially square layout, fully utilizes the space of the valve body 1 in the width direction and the thickness direction, greatly reduces the installation height of the entire wall-mounted stove waterway system, and optimizes the space layout of the entire system.

[0046] As shown in Figure 2 and Figure 3As shown, the three-way valve cavity 110 includes a first cavity 1102, a main valve cavity 1101 and a second cavity 1103 which are sequentially communicated along a first direction, the main valve cavity 1101 is communicated with the hot water outlet of the combustion chamber, and the main valve cavity 1101 can selectively communicate the first cavity 1102 or the second cavity 1103; the heating channel 121 is communicated with the first cavity 1102, and the heat exchange water inlet flow channel 131 is communicated with the second cavity 1103. When the main valve cavity 1101 is communicated with the first cavity 1102, the hot water in the combustion chamber can be circulated in the heating water circulation loop; when the main valve cavity 1101 is communicated with the second cavity 1103, the hot water in the combustion chamber can be circulated in the heat exchange circulation loop.

[0047] As shown in Figure 3 , the second cavity 1103 and the heat exchange water inlet flow channel 131 are communicated through the second communication flow channel 1002, and the axis of the second communication flow channel 1002 is inclined relative to the axis of the three-way valve cavity 110. With this design, on the one hand, compared with the straight channel in the prior art, the embodiment increases the cross-sectional area of the second communication flow channel 1002 inlet, thereby reducing the water resistance from the second cavity 1103 to the heat exchange water inlet flow channel 131; on the other hand, it is convenient for the processing of the second communication flow channel 1002, reduces the use of sealing plugs, and at the same time can reduce the potential risk point of leakage.

[0048] Optionally, the inclination angle of the second communication flow channel 1002 relative to the axis of the three-way valve cavity 110 is 25°-75°. This angle range can facilitate the processing of the valve body 1, and can avoid the size of the valve body 1 in the left-right direction or the front-back direction being too large, resulting in a larger installation space of the water outlet valve and increasing the installation difficulty. Exemplarily, the inclination angle of the second communication flow channel 1002 relative to the axis of the three-way valve cavity 110 can be 30°, 40°, 45°, 50°, 60°, etc.

[0049] As shown in Figure 1 and Figure 2 , the water outlet valve further includes a switching mechanism 3 which is movably arranged in the three-way valve cavity 110 to selectively communicate the heating channel 121 or the heat exchange water inlet flow channel 131. That is, by moving the switching mechanism 3 in the three-way valve cavity 110, the passage between the main valve cavity 1101 and the first cavity 1102 or the passage between the main valve cavity 1101 and the second cavity 1103 can be selectively opened, so as to realize three-way switching. The specific structure and working principle of the switching mechanism 3 will not be described herein, and the switching mechanism which can be applied to the water outlet valve in the prior art to realize three-way switching in the three-way valve cavity 110 is within the protection scope of the embodiment.

[0050] Further, the water outlet valve further comprises a driving mechanism 2, an output end of the driving mechanism 2 is connected to the switching mechanism 3 to drive the switching mechanism 3 to move in the three-way valve cavity 110. In the embodiment, the driving mechanism 2 is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 3, the driving mechanism 2 can also be a stepping motor or other driving device.

[0051] It should be noted that by arranging the three-way valve part 11 along the front-rear direction, the driving mechanism 2 can also be installed on the front side of the valve body 1 (the driving mechanism in the prior art is usually installed between the valve body and the combustion chamber, i.e., the driving mechanism is installed on the upper part of the valve body), so as to avoid the interval area between the valve body 1 and the combustion chamber, fully utilize the space of the valve body 1 in the thickness direction, and further shorten the interval between the valve body 1 and the combustion chamber, thereby reducing the height of the entire wall-mounted stove water system.

[0052] Continuing as shown in Figure 2 The valve body 1 is further provided with a machining hole 1003 extending into the valve body 1 along the axis direction of the machining hole 1003 to form the first communication flow channel 1001, and the machining hole 1003 is sealingly connected with a plugging structure 4. By arranging the machining hole 1003, the operator can continue to drill into the valve body 1 along the axis direction of the machining hole 1003 to form the first communication flow channel 1001, thereby facilitating the machining of the first communication flow channel 1001, saving time and effort, and improving the machining efficiency of the water outlet valve, and avoiding interference between the drilling tool and other structures on the valve body 1 when machining the first communication flow channel 1001; by arranging the plugging structure 4, the machining hole 1003 can be sealed to prevent water in the valve body 1 from leaking from the machining hole 1003, thereby ensuring the use safety of the entire water outlet valve.

[0053] In the embodiment, the axis direction of the machining hole 1003 is parallel to the axis direction of the three-way valve cavity 110, so as to facilitate accurate positioning of the operator when machining the machining hole 1003, and further improve the machining convenience of the first communication flow channel 1001.

[0054] Optionally, the projection of the machining hole 1003 on the reference plane 1000 overlaps with the projection of the three-way valve cavity 110 on the reference plane 1000, and overlaps with the projection of the heating passage 121 on the reference plane 1000; wherein the reference plane 1000 passes through the axis of the heating passage 121 and is perpendicular to the axis direction of the three-way valve cavity 110. By adopting this arrangement, the operator can make the first communication flow channel 1001 directly communicate with the three-way valve cavity 110 and the heating passage 121 during the process of drilling the machining hole 1003 to form the first communication flow channel 1001, without changing the machining path, and the machining efficiency can be further improved.

[0055] To ensure the sealing between the plugging structure 4 and the machining hole 1003, at least one sealing element 5 is arranged between the plugging structure 4 and the machining hole 1003. The sealing element 5 can be an O-shaped sealing ring, and the number of the O-shaped sealing ring is not limited in the embodiment, which can be two, three or more, and the number of the sealing element 5 can be adjusted according to the actual sealing requirement. Alternatively, the outer wall of the plugging structure 4 is provided with a containing groove 41 for containing the sealing element 5, so as to stably install the sealing element 5 and avoid the sealing element 5 from falling off or moving in the use process. Of course, in other embodiments, the containing groove 41 can also be arranged on the hole wall of the machining hole 1003, which can also achieve the above effect.

[0056] In some embodiments, the plugging structure 4 is a sealing plug, which is simple in structure, easy to install, convenient to obtain materials, and can reduce the machining cost to a certain extent.

[0057] In some embodiments, the plugging structure 4 can be a sensing component. The sensing component can be a temperature detection element or a pressure detection element, which is used to detect the temperature or pressure of the water flowing from the three-way valve cavity 110 to the heating channel 121, so as to control other mechanisms according to the current temperature or pressure of the water in the three-way valve cavity 110, realize the normal use of the entire wall-mounted stove water system, and improve the use experience of the user.

[0058] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Without departing from the spirit and scope of the present application, various changes and modifications can be made to the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
