[0052] The embodiment provides a water outlet valve applied to a wall-hanging stove water system. The connection relationship and working principle of the water outlet valve, the water inlet valve, the heat exchange structure and the burner of the wall-hanging stove water system are prior art, and the embodiment will not be repeated. The water outlet valve in the related art is mostly constant flow, that is, the fluid flow at the bathroom outlet of the water outlet valve is constant. Due to the limitation of factors such as building height, the water pressure of different floor heights is different, and the use of the same type of water outlet valve has different experience effects for users of different floor heights, so that the use experience of users of some floors is poor. To solve this problem, the embodiment provides a water outlet valve capable of adjusting the fluid flow at the bathroom outlet to meet the use demand of users. The specific structure of the water outlet valve provided by the embodiment is described in detail below with reference to the drawings.

[0053] Figure 1The diagram shows a schematic of the outlet valve provided in this embodiment from one perspective. Figure 2 A cross-sectional view of the water outlet valve provided in this embodiment is shown in one direction. Figures 1-2 As shown, the water outlet valve provided in this embodiment includes a water outlet valve body 100 and a flow regulating mechanism 200. The water outlet valve body 100 has a heat exchange water outlet channel 1302, a bathroom channel 1303, and a first mounting port. The heat exchange water outlet channel 1302 is connected to the heat exchange structure to receive hot water flowing out from the heat exchange structure. The flow regulating mechanism 200 includes a valve body 1 and a driving member 2. The valve body 1 is partially inserted into the first mounting port. The valve body 1 has an inlet channel 111 and an outlet channel 121 surrounding the inlet channel 111. The inlet of the inlet channel 111 is connected to the heat exchange water outlet channel 1302, and the outlet of the outlet channel 121 is connected to the bathroom channel 1303. The driving member 2 is installed on the valve body 1, and the driving member 2 is configured to selectively connect the passage between the inlet channel 111 and the outlet channel 121, and can regulate the flow rate in the passage between the inlet channel 111 and the outlet channel 121.

[0054] The water outlet valve provided in this embodiment, by setting an inlet channel 111 and an outlet channel 121 surrounding the inlet channel 111 inside the valve body 1, allows the operator to simultaneously form the outlet channel 121 outside the inlet channel 111 in a pipeline facing the same direction during processing, thereby simplifying the structure of the entire water outlet valve, reducing its overall volume, improving processing efficiency, and reducing processing costs; by setting a driving component 2, the passage between the inlet channel 111 and the outlet channel 121 is selectively connected, and the water flow rate in the passage is adjusted, thereby realizing the adjustment of the water flow rate between the heat exchange outlet channel 1302 and the bathroom channel 1303, so as to meet the different water consumption needs of users and improve the user experience.

[0055] Figure 3 A cross-sectional view of the flow regulation mechanism 200 provided in this embodiment is shown. Figure 3 and combined Figure 2 As shown, the valve body 1 also has a connecting port 112 that connects the inlet channel 111 and the outlet channel 121. The driving component 2 includes a servo motor 21, which includes a motor body 211 and a regulating valve core 212 connected to the motor body 211. A sealing part 2121 is formed on the outer periphery of the regulating valve core 212. The servo motor 21 can drive the regulating valve core 212 to move, thereby adjusting the distance between the sealing part 2121 and the connecting port 112, thus realizing the regulation of the water flow in the passage between the inlet channel 111 and the outlet channel 121. Since the servo motor 21 has the advantages of high precision, stable operation, high reliability and easy maintenance, it can realize the precise regulation of the water flow between the inlet channel 111 and the outlet channel 121.

[0056] In operation, the motor body 211 can drive the blocking part 2121 to move between the first position and the second position. When the blocking part 2121 is located at the first position, the outer contour of the blocking part 2121 can completely cover the communication port 112, so that the minimum water flow through the communication port 112 can be close to 0, thereby increasing the adjustment interval of the water flow; when the blocking part 2121 is located at the second position, the spacing between the blocking part 2121 and the communication port 112 is maximum, so that the water flow through the communication port 112 is maximum. In the present embodiment, the motor body 211 can drive the blocking part 2121 to move to any position between the first position and the second position, so that the water flow through the communication port 112 is adjusted between the minimum value and the maximum value. The present embodiment does not limit the maximum spacing between the blocking part 2121 and the communication port 112, and the designer can adaptively adjust it according to actual needs. Specifically, referring to the dashed arrow in Figure 2 , when the blocking part 2121 moves to any position between the first position and the second position, that is, the communication port 112 is opened, the hot water flowing out from the heat exchange structure into the heat exchange outlet water channel 1302 can flow into the bathroom channel 1303 in sequence through the inlet water passage 111, the communication port 112 and the outlet water passage 121.

[0057] Figure 4 The structure schematic diagram of the flow adjusting mechanism 200 provided by the present embodiment is shown. Figure 5 The front view of the flow adjusting mechanism 200 provided by the present embodiment is shown. Figure 6 is a structure schematic diagram of the valve body 1 in one view provided by the present utility model. As Figures 4-6 and in combination with Figure 2 , Figure 3 , the valve body 1 comprises a main valve part 13, an inlet water branch pipe 11 and an outlet water branch pipe 12, the main valve part 13 is provided with a water passing cavity 131; the outlet water branch pipe 12 is connected to the main valve part 13, part of the inlet water branch pipe 11 is inserted into the outlet water branch pipe 12, the inlet water passage 111 is provided in the inlet water branch pipe 11, the gap between the outer wall of the inlet water branch pipe 11 and the inner wall of the outlet water branch pipe 12 forms the outlet water passage 121, and the inlet water passage 111 and the outlet water passage 121 can both communicate with the water passing cavity 131 through the communication port 112. In the present embodiment, the opening of the inlet water branch pipe 11 close to the blocking part 2121 forms the above-mentioned communication port 112, that is, when the blocking part 2121 is at the first position, it blocks the opening position of the inlet water branch pipe 11.

[0058] Optionally, the axis of the water inlet branch pipe 11 and the axis of the water outlet branch pipe 12 are arranged at intervals along the height direction of the water outlet valve body 100. With this arrangement, the spacing between the inner wall of the water outlet passage 121 and the outer wall of the water inlet passage 111 can gradually increase from top to bottom, so as to adapt to the flow mode that water in the water inlet passage 111 is mostly gathered in the lower part of the water inlet passage 111 due to gravity, thereby improving the flow-through efficiency of water in the water inlet passage 111.

[0059] In the present embodiment, as shown in Figure 5 , the spacing L between the axis of the water inlet branch pipe 11 and the axis of the water outlet branch pipe 12 is 0.1 mm to 10 mm. Exemplarily, L can be 0.2 mm, 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm, 6.0 mm, 7.0 mm, 8.0 mm, 9.0 mm, etc. The designer can adjust the specific value of L according to actual use requirements, which is not limited in the present embodiment.

[0060] As shown in Figure 4 and Figure 6 , part of the outer wall of the water inlet branch pipe 11 is in close contact with the inner wall of the water outlet branch pipe 12. With this arrangement, on the one hand, the eccentricity between the water inlet branch pipe 11 and the water outlet branch pipe 12 can be maximized, further ensuring that the water flow in the water outlet passage 121 has a high flow-through efficiency; on the other hand, it is also convenient for fixing the water inlet branch pipe 11, i.e. the water inlet branch pipe 11 can be directly fixed and connected in the water outlet branch pipe 12, without the need for additionally arranging a bracket for fixing the water inlet branch pipe 11, thereby simplifying the processing technology and reducing the material cost to a certain extent.

[0061] Continuing as shown in Figure 2 and Figure 3 , the driving member 2 further comprises a support sleeve 22, and the valve body 1 is further provided with a second mounting port 132 for mounting the driving member 2, and the support sleeve 22 is sealingly connected to the second mounting port 132, and the adjusting valve core 212 is threaded into the support sleeve 22. When the motor body 211 is started, it can drive the adjusting valve core 212 to rotate, thereby driving the plugging part 2121 to move along the axis direction of the adjusting valve core 212 to approach or move away from the communication port 112. By arranging the support sleeve 22, the transmission support of the adjusting valve core 212 can be increased.

[0062] Specifically, the support sleeve 22 comprises a transmission matching portion 221 and an inner sealing portion 222 connected with each other, the transmission matching portion 221 is sealingly connected to the second mounting port 132, the transmission matching portion 221 is threadedly matched with the adjusting valve core 212, and the inner sealing portion 222 sealingly covers the outer periphery of the adjusting valve core 212 and is slidably matched with the adjusting valve core 212. In the embodiment, a third sealing member 231 is arranged between the inner sealing portion 222 and the adjusting valve core 212, so as to ensure the sealing performance of the transmission portion of the adjusting valve core 212 and the water flow area in the valve body 1; and a fourth sealing member 232 is further arranged between the transmission matching portion 221 and the second mounting port 132, so as to enhance the sealing performance of the servo motor 21 and the water flow area in the valve body 1, thereby protecting the power element. In the embodiment, the third sealing member 231 and the fourth sealing member 232 can each be an O-shaped sealing ring, and the number of layers of the O-shaped sealing ring is not limited; for example, the third sealing member 231 can be provided with one, two, three or more layers.

[0063] Optionally, the support sleeve 22 is provided with a limiting portion capable of abutting against the blocking portion 2121, and the limiting portion is used for limiting the maximum distance of the blocking portion 2121 from the communication port 112. That is, when the blocking portion 2121 is located at the second position, the blocking portion 2121 abuts against the limiting portion of the support sleeve 22, so as to limit the maximum opening degree of the blocking portion 2121 by the position of the limiting portion, thereby facilitating the determination of the maximum value of the water flow. When designing the flow regulating valve, the maximum opening degree of the blocking portion 2121 can be changed by changing the length of the inner sealing portion 222, so as to change the regulating range of the regulating water flow. In the embodiment, the free end of the inner sealing portion 222 of the support sleeve 22 forms the limiting portion.

[0064] Figure 7 Fig. 4 shows a structural schematic diagram of the valve body 1 in another view according to the embodiment. Figure 7 In combination with Figure 3 As shown in Fig. 4, the valve body 1 (specifically, the main valve portion 13) is further provided with a guide groove 133, and the end of the adjusting valve core 212 away from the motor body 211 is slidably arranged in the guide groove 133. During the movement of the motor body 211 driving the adjusting valve core 212, the adjusting valve core 212 can be guided and limited by the guide groove 133, so as to ensure the stability of the adjusting valve core 212 during the movement.

[0065] In order to realize the stable connection between the driving member 2 and the valve body 1, as shown in Fig. 5, Figure 3 the driving member 2 is connected to the main valve portion 13 of the valve body 1 by a fastening screw 3, and the screw connection has the advantages of convenient disassembly and assembly and tight connection.

[0066] Figure 8 Fig. 6 shows an exploded structural schematic diagram of the flow regulating mechanism 200 according to the embodiment. As shown in Fig. 6, Figure 8 In combination withFigure 3 As shown, the first sealing member 301 is arranged between the water outlet branch pipe 12 and the first mounting port to avoid water flowing out of the communication port 112 from leaking through the gap between the water outlet branch pipe 12 and the first mounting port, thereby ensuring the safety of the entire water outlet valve.

[0067] Optionally, the second sealing member 302 is arranged between the water inlet branch pipe 11 and the cavity wall of the heat exchange water outlet flow channel 1302 to avoid hot water in the heat exchange water outlet flow channel 1302 from directly flowing into the bathroom channel 1303 through the gap between the water inlet branch pipe 11 and the heat exchange water outlet flow channel 1302, thereby affecting the accuracy of the fluid flow rate at the outlet of the bathroom channel 1303.

[0068] Figure 9 A structural schematic diagram of the water outlet valve provided by the embodiment is shown from another perspective. Figure 10 A cross-sectional schematic diagram of the water outlet valve provided by the embodiment is shown in another direction. Figures 8-9 and in combination with Figure 1 As shown, the water outlet valve body 100 includes a three-way valve part 110, a heating valve part 120, and a heat exchange valve part 130. The three-way valve part 110 is internally provided with a three-way valve cavity extending in a first direction. The heating valve part 120 is connected to the three-way valve part 110, and the heating valve part 120 is internally provided with a heating channel 1201 extending in a second direction. The heat exchange valve part 130 is connected to one side of the three-way valve part 110 and the heating valve part 120 along a third direction, and the heat exchange valve part 130 is internally provided with a heat exchange water outlet flow channel 1302, a bathroom channel 1303, and a first mounting port. The heat exchange valve part 130 also has a heat exchange water inlet flow channel 1301. The three-way valve cavity can selectively communicate with the heating channel 1201 or the heat exchange water inlet flow channel 1301. This design can distribute the entire structure size of the water outlet valve body 100 in three directions arranged at an angle with each other in three-dimensional space, so as to avoid the length of the water outlet valve body 100 in the axial direction of the three-way valve cavity being too long, thereby optimizing the spatial layout of the entire water outlet valve.

[0069] It should be explained that in the embodiment, the height direction of the water outlet valve after actual installation is defined as the up-down direction, wherein 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 water outlet valve body 100 refers to the up-down direction, the width direction of the water outlet valve body 100 refers to the left-right direction, and the thickness direction of the water outlet valve body 100 refers to the front-back direction. 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.

[0070] In other words, in the embodiment, the three-way valve part 110 extends along the front-rear direction, the heating valve part 120 is connected to the lower part of the three-way valve part 110, and the heat exchange valve part 130 is connected to the right side of the three-way valve part 110 and the heating valve part 120, so that the entire water outlet valve main body 100 is arranged in a substantially square shape, the space of the water outlet valve main body 100 in the width direction and the thickness direction is fully utilized, the installation height of the entire wall-mounted stove water system is greatly reduced, and the spatial layout of the entire system is optimized. In addition, in the embodiment, the axis of the three-way valve cavity, the axis of the heating channel 1201, and the extension direction of the heat exchange valve part 130 are arranged perpendicular to each other in pairs. Of course, in other embodiments, the three-way valve cavity, the heating channel 1201, and the extension direction of the heat exchange valve part 130 can also be arranged at other angles between each other, which can also achieve the above-mentioned effects.

[0071] Optionally, the three-way valve cavity comprises a first cavity 1102, a main valve cavity 1101, and a second cavity 1103 which are sequentially communicated along the first direction, the main valve cavity 1101 is in communication with the combustion chamber, and the main valve cavity 1101 can selectively communicate the first cavity 1102 or the second cavity 1103; the heating channel 1201 is in communication with the first cavity 1102, and the heat exchange water inlet flow channel 1301 is in communication with the second cavity 1103. When the main valve cavity 1101 is in communication with the first cavity 1102, the hot water in the combustion chamber can flow to the heating channel 1201 through the main valve cavity 1101 and the first cavity 1102 to provide heating demand for the user; when the main valve cavity 1101 is in communication with the second cavity 1103, the hot water in the combustion chamber can flow to the heat exchange structure through the main valve cavity 1101, the second cavity 1103, and the heat exchange water inlet flow channel 1301 to exchange heat with the domestic water in the heat exchange structure, thereby providing domestic water for the user.

[0072] Optionally, the water outlet valve further comprises a switching mechanism 500 and a driving mechanism 400, the driving mechanism 400 is arranged on the water outlet valve main body 100, and the output end thereof is connected with the switching mechanism 500 to drive the switching mechanism 500 to move in the three-way valve cavity, so as to selectively communicate the heating channel 1201 or the heat exchange water inlet flow channel 1301. That is, by the movement of the switching mechanism 500 in the three-way valve cavity, 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, thereby realizing three-way switching. The specific structure and working principle of the switching mechanism 500 are not described again in the embodiment, and the switching mechanism capable of being applied to the water outlet valve to realize three-way switching in the three-way valve cavity in the prior art is within the protection scope of the embodiment.

[0073] In the embodiment, the driving mechanism 400 is a synchronous motor. Of course, in other embodiments, according to different designs of the switching mechanism 500, the driving mechanism 400 can also be a stepping motor, a servo motor or other driving devices.

[0074] It should be noted that by arranging the three-way valve part 110 in the front-rear direction, the driving mechanism 400 can also be installed on the front side of the outlet valve body 100 (the driving mechanism in the prior art is usually installed between the outlet valve body and the combustion chamber, i.e. the driving mechanism is installed on the upper part of the outlet valve body), so as to avoid the interval area between the outlet valve body 100 and the combustion chamber, fully utilize the space of the outlet valve body 100 in the thickness direction, further shorten the interval between the outlet valve body 100 and the combustion chamber, and reduce the height of the entire wall-mounted boiler waterway system.

[0075] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
