[0037] A wall-mounted boiler is a commonly used household heating device that integrates bathroom and heating functions and realizes these two functions through different channels.

[0038] When the existing wall-mounted boiler is working, the bathroom outlet water temperature on the outlet valve of the wall-mounted boiler fluctuates greatly, and it takes a long time for the water temperature to stabilize. Especially when the bathroom inlet water temperature of the outlet valve is relatively high, such as in summer or when the wall-mounted boiler has a stop water temperature rise situation, even if the wall-mounted boiler burns at the minimum power, the bathroom outlet water temperature is still relatively high, which cannot meet the user's demand for a lower bathroom water temperature and affects the user experience. The comfort level is not high.

[0039] The present utility model proposes an outlet valve 100 for a wall-mounted boiler.

[0040] Please refer to Figures 1 to 8As shown, in an embodiment of the present utility model, the water outlet valve 100 includes a valve body 10 and a flow rate regulating assembly 20. A sanitary ware water flow channel 12 is provided inside the valve body 10, as well as a high-temperature water inlet channel 11 and a low-temperature water inlet channel 13 that are communicated with the input end of the sanitary ware water flow channel 12. The flow rate regulating assembly 20 is arranged in the valve body 10. The flow rate regulating assembly 20 is used for electrically connecting to a control member 200 of a wall-mounted boiler, and regulating the water flow rate of the low-temperature water inlet channel 13 according to the instruction of the control member 200.

[0041] In the present utility model, the water inlet temperature of the low-temperature water inlet channel 13 is lower than the water inlet temperature of the high-temperature water inlet channel 11. The low-temperature water inlet channel 13 can be used to connect to a normal-temperature tap water system or a near-zero-degree ice water input pipeline. The high-temperature water inlet channel 11 can be used to connect to the high-temperature water outlet pipeline of the wall-mounted boiler. The sanitary ware water flow channel 12 can be used to connect to the sanitary ware water outlet system of the wall-mounted boiler. Among them, the high-temperature water inlet channel 11 is connected to the sanitary ware water flow channel 12 to form a sanitary ware flow channel arranged on the water outlet valve 100. The control member 200 is a part of the wall-mounted boiler control system itself and can be electrically connected to the flow rate regulating assembly 20 in a wired or wireless manner, and is used to send an instruction to the flow rate regulating assembly 20 to make the flow rate regulating assembly 20 regulate the water flow rate of the low-temperature water inlet channel 13.

[0042] The low-temperature water inlet channel 13 is provided with a low-temperature water inlet 131 for connecting to a tap water system. The sanitary ware high-temperature water inlet channel 11 is provided with a high-temperature water inlet 111 for connecting to the high-temperature water outlet pipeline of the wall-mounted boiler. The output end of the sanitary ware water flow channel 12 is provided with a sanitary ware water outlet 121, and the sanitary ware water outlet 121 is used for connecting to the sanitary ware water outlet system of the wall-mounted boiler.

[0043] The technical solution of the present utility model is based on the sanitary ware flow channel formed by connecting the existing high-temperature water inlet channel 11 and the sanitary ware water flow channel 12. A low-temperature water inlet channel 13 is added, and the low-temperature water inlet channel 13 is connected to the output end of the sanitary ware water flow channel 12. When high-temperature water is output from the high-temperature water inlet channel 11 to the sanitary ware water flow channel 12, low-temperature water can be introduced into the sanitary ware water flow channel 12 through the low-temperature water inlet channel 13 and mixed with the high-temperature water to reduce the output water temperature of the sanitary ware water flow channel 12. And a flow rate regulating assembly 20 is provided to regulate the opening degree of the low-temperature water inlet channel 13, so as to be able to regulate the flow rate of the low-temperature water input into the sanitary ware water flow channel 12, and thus the output water temperature can be regulated according to the water temperature required by the user, so as to meet the use experience of the user using the sanitary ware water outlet system of the wall-mounted boiler in summer, and avoid the situation of relatively high output water temperature caused by the temperature rise when the wall-mounted boiler stops heating.

[0044] Refer to Figure 1 , Figure 3As shown, in an embodiment of the utility model, the water outlet valve also includes a temperature measuring element 30, which is arranged in the bathroom water outlet channel 12. The temperature measuring element 30 is used to measure the water temperature in the bathroom water outlet channel 12. The temperature measuring element 30 is used to electrically connect the control component 200 so that the control component 200 can control the flow regulating component 20 according to the feedback signal of the temperature measuring element 30.

[0045] In the above-mentioned embodiments, the temperature measuring element 30 can be configured as one of a thermocouple, a thermal resistor, an infrared temperature sensor or a fiber optic temperature sensor, which is not limited here.

[0046] When in use, the above-mentioned temperature measuring element 30 can be set on the inner wall forming the bathroom water outlet channel 12. The above-mentioned temperature measuring element 30 can be electrically connected to the control component 200 through a wired connection to transmit the water temperature signal inside the bathroom water outlet channel 12 to the control component 200. The control component 200 can control the operation of the flow regulating component 20 according to the acquired water temperature signal, adjust the opening of the low-temperature water inlet channel 13, and adjust the output water temperature of the bathroom water outlet channel 12 by adjusting the flow of the low-temperature water inlet channel 13.

[0047] Alternatively, in other embodiments, the temperature measuring element 30 can also transmit signals to the control component 200 via a wireless connection. Such a setting can reduce the line setting and there is no need to drill holes in the pipe wall forming the bathroom water outlet channel 12 for threading.

[0048] In an embodiment of the utility model, the flow regulating component 20 is used to increase the water flow rate of the low-temperature water inlet channel 13 according to the instruction of the control component 200 when the water temperature in the low-temperature water inlet channel 13 is lower than the preset value. The flow regulating component 20 is used to reduce the water flow rate of the low-temperature water inlet channel 13 according to the instruction of the control component 200 when the water temperature in the low-temperature water inlet channel 13 is higher than the preset value.

[0049] The preset value is the water temperature of the bathroom water that the user intends to use, and the preset value can be adjusted according to the actual usage. When the bathroom water outlet system of the wall-mounted boiler is used in summer, the preset value can be appropriately lowered, and when the bathroom water outlet system of the wall-mounted boiler is used in winter, the preset value can be appropriately increased.

[0050] With such a setting, the control member 200 can compare the temperature value in the bathroom water outlet channel 12 measured in real time by the temperature measuring element 30 with a preset value. When the obtained temperature value is less than the preset value, the control flow regulating assembly 20 will reduce the opening degree of the low-temperature water inlet channel 13, so that the low-temperature water entering the bathroom water outlet channel 12 is reduced, and the water temperature after mixing with the high-temperature water is increased, thereby raising the water temperature. When the obtained temperature value is greater than the preset value, the control flow regulating assembly 20 will increase the opening degree of the low-temperature water inlet channel 13, so that the low-temperature water entering the bathroom water outlet channel 12 is increased, and the water temperature after mixing with the high-temperature water is decreased, thereby reducing the water temperature.

[0051] Refer to Figure 1 、 Figure 3 As shown, in the embodiment of the present invention, the temperature measuring element 30 is arranged close to the input end of the bathroom water outlet channel 12. With such a setting, the water temperature after mixing from the high-temperature water inlet channel 11 and the bathroom water outlet channel 12 into the bathroom water outlet channel 12 can be measured at a position closer to the input end of the bathroom water outlet channel 12. When there is a difference between the measured water temperature and the preset value, since the measuring position is at a longer distance from the bathroom water outlet 121, there is enough space in the bathroom water outlet channel 12 for the mixing of high-temperature water and low-temperature water after the flow rate of the low-temperature water inlet channel 13 changes, so that the water temperature output from the bathroom water outlet 121 is closer to the preset value.

[0052] Alternatively, in other embodiments, the temperature measuring element 30 can be provided in multiple numbers, and the multiple temperature measuring elements 30 are spaced apart along the extending path of the bathroom water outlet channel 12. In this way, the water temperature at each part in the bathroom water outlet channel 12 can be measured, and thus the water temperature after mixing in the bathroom water outlet channel 12 can be measured more accurately.

[0053] In other embodiments, a mixing assembly can also be provided in the bathroom water outlet channel 12. The mixing assembly is used to disturb the water in the bathroom water outlet channel 12 to accelerate the mixing of the high-temperature water from the high-temperature water inlet channel 11 and the low-temperature water from the low-temperature water inlet channel 13. Among them, the mixing assembly can be arranged between the temperature measuring element 30 and the output end of the bathroom water outlet channel 12.

[0054] Among them, the mixing assembly can be set as a driverless impeller. The rotation center of the driverless impeller is arranged along the extending direction of the bathroom water outlet channel 12. When the high-temperature water from the high-temperature water inlet channel 11 and the low-temperature water from the low-temperature water inlet channel 13 collide and disturb when entering the bathroom water outlet channel 12, it will drive the driverless impeller to rotate, thereby accelerating the mixing of high-temperature water and low-temperature water.

[0055] Refer to Figure 1 、 Figure 3 、 Figure 4As shown, in the embodiment of the present utility model, the flow rate adjustment assembly 20 includes a driving member 22 and a valve core 21 drivingly connected to the driving member 22. The valve core 21 is disposed in the low-temperature water inlet channel 13, and the driving member 22 is used to drive the valve core 21 to move within the low-temperature water inlet channel 13 so as to adjust the water flow rate of the low-temperature water inlet channel 13.

[0056] Among them, the driving member 22 can drive the valve core 21 to rotate within the low-temperature water inlet channel 13 to adjust the water flow rate, such as a ball valve or a butterfly valve can be used; or the driving member 22 can drive the valve core 21 to linearly move within the low-temperature water inlet channel 13 to adjust the water flow rate, such as a globe valve or a pneumatic control valve can be used.

[0057] Continue to refer to Figure 1 、 Figure 3 、 Figure 4 In the embodiment of the present utility model, the valve core 21 includes a valve core body 212 disposed in the low-temperature water inlet channel 13 and a rotating portion 211 drivingly connected to the driving member 22;

[0058] One end of the valve core body 212 away from the rotating portion 211 abuts against the inner wall of the valve body 10. A water passing groove 2121 is formed on the circumferential side of the valve core body 212. A water passing gap is formed between the water passing groove 2121 and the inner wall of the low-temperature water inlet channel 13. The driving member 22 is used to drive the valve core body 212 to rotate so as to adjust the size of the water passing gap.

[0059] In the above embodiment, the present utility model selects the method of driving the driving member 22 to rotate within the low-temperature water inlet channel 13 to adjust the water flow rate. Since a water passing groove 2121 is formed on one side of the valve core body 212, a water passing gap is formed between the water passing groove 2121 and the inner wall of the low-temperature water inlet channel 13. When the driving member 22 drives the valve core body 212 to rotate, the gap between the water passing groove 2121 and the inner wall of the low-temperature water inlet channel 13 will change. When the water passing groove 2121 faces the inner wall of the low-temperature water inlet channel 13, the gap between the two is the largest, which can provide the largest water passing gap for the low-temperature water inlet channel 13. When the water passing groove 2121 faces away from or faces the low-temperature water inlet 131, there is no gap or the gap is the smallest between the water passing groove 2121 and the inner wall of the low-temperature water inlet channel 13, so as to provide the smallest water passing gap for the low-temperature water inlet channel 13. When the valve core body 212 rotates, it can gradually change between the largest water passing gap and the smallest water passing gap to realize the adjustment of the water flow rate.

[0060] Refer to Figure 3 、 Figure 4As shown, in an embodiment of the present utility model, the valve core body 212 and the inner wall of the low-temperature water inlet channel 13 are provided with a second sealing portion 132, and the first sealing portion 2122 is used to seal with the second sealing portion 132 when the valve core body 212 is rotated to a preset position, so that the water flow from the low-temperature water inlet channel 13 to the bathroom water outlet channel 12 is blocked by the first sealing portion 2122 when the valve core body 212 is rotated to a preset position.

[0061] In the above-mentioned embodiment, the preset position refers to the position where the first sealing portion 2122 can be sealed and docked with the second sealing portion 132. When a water gap is formed between the water groove 2121 and the inner wall of the low-temperature water inlet channel 13, the first sealing portion 2122 and the second sealing portion 132 are docked with the surrounding wall away from the water groove 2121, so that the water in the low-temperature water inlet channel 13 can only flow out from the water gap and cannot flow out from other positions. When the water groove 2121 is facing or facing away from the low-temperature water inlet 131, a water gap cannot be formed between the water groove 2121 and the inner wall of the low-temperature water inlet channel 13, and since the first sealing portion 2122 is docked with the second sealing portion 132, the water in the low-temperature water inlet channel 13 cannot flow into the bathroom water outlet channel 12, thereby achieving complete blocking of the water outlet of the low-temperature water inlet channel 13.

[0062] See also Figure 3 , Figure 6 , Figure 8 As shown, optionally, the first sealing portion 2122 is an outer arc-shaped peripheral wall of the valve core body 212, and the second sealing portion 132 is an inner arc-shaped groove opened on the inner wall of the low-temperature water inlet flow channel 13;

[0063] And / or, one end of the valve core body 212 away from the rotating portion 211 is a spherical surface, and when the valve core body 212 rotates, the spherical surface seals with the inner wall surface of the low-temperature water inlet channel 13.

[0064] Among them, two inner arc grooves can be provided, and the two inner arc grooves are relatively arranged in the low-temperature water inlet channel 13. During the rotation of the valve core body 212, the outer arc-shaped circumferential wall of the valve core body 212 can at least abut against one of the inner arc grooves, and the other inner arc groove can form a water-passing gap with the water-passing groove 2121, or when the water-passing groove 2121 rotates to face the low-temperature water inlet 131 or away from the low-temperature water inlet 131, the arc-shaped outer circumferential wall of the valve core body 212 abuts against both inner arc grooves, and there is no gap for water to pass between the valve core body 212 and the low-temperature water inlet channel.

[0065] In addition, one end of the valve core body 212 away from the rotating part 211 can be set to be spherical, which is used for sealing cooperation with the arc-shaped inner wall of the low-temperature water inlet channel 13. During the rotation of the valve core body 212, the end of the valve core body 212 away from the rotating part 211 can always be in sealing cooperation with the arc-shaped inner wall of the low-temperature water inlet channel 13, thereby preventing water from leaking from this place.

[0066] Optionally, the driving member 22 is a stepping motor. In this way, the rotation angle of the valve core 21 can be controlled more precisely to achieve servo control and more precise adjustment of the water flow rate. Of course, in other embodiments, the driving member can also be set as a servo motor, which is not limited herein.

[0067] Refer to Figure 3 As shown, in the embodiment of the present utility model, the low-temperature water inlet channel 13 has an output end connected to the bathroom water outlet channel 12, and the valve core 21 is arranged at the output end of the low-temperature water inlet channel 13.

[0068] With such a setting, the valve core 21 can be arranged closer to the bathroom water outlet channel 12, so as to shorten the flow path length from the water outlet position of the low-temperature water inlet channel 13 to the bathroom water outlet channel 12. When adjusting the water temperature, low-temperature water can be input into the bathroom water outlet channel 12 more quickly, thereby improving the response speed of water temperature adjustment.

[0069] In addition, such a setting can also prevent the water flowing from the high-temperature water inlet channel 11 to the bathroom water outlet channel 12 from flowing back into the low-temperature water inlet channel 13.

[0070] In other embodiments, the valve core 21 can also be arranged at a position close to the bathroom water outlet 121, which can also achieve the delivery of low-temperature water into the bathroom water outlet channel 12, which is not limited herein.

[0071] Optionally, a check valve structure is also arranged in the low-temperature water inlet channel 13. The check valve structure is arranged on the flow path between the valve core 21 and the output end of the low-temperature water inlet channel 13, and the check valve structure is used to control the unidirectional flow of water from the low-temperature water inlet 131 towards the output end of the low-temperature water inlet channel 13.

[0072] With such a setting, when the high-temperature water inlet channel 11 delivers high-temperature water to the bathroom water outlet channel 12 and the valve core 21 opens the low-temperature water inlet channel 13, it can be avoided that the water pressure in the high-temperature water inlet channel 11 is higher than the water pressure in the low-temperature water inlet channel 13, resulting in the water in the high-temperature water inlet channel 11 flowing back into the low-temperature water inlet channel 13. Since the low-temperature water inlet channel 13 is connected to the water supply pipeline, it can be avoided that the water in the wall-mounted boiler pollutes the water supply pipeline.

[0073] Refer to Figure 1 、 Figure 3 、 Figure 7As shown, in the embodiment of the present utility model, a heating flow channel 14 is further provided in the valve body 10, and the heating flow channel 14 is arranged at an interval from the bathroom water outlet flow channel 12.

[0074] Among them, the heating flow channel 14 has a heating water inlet 142 and a heating water outlet 141. The heating water inlet 142 is used to connect to the high-temperature water outlet system of the wall-mounted boiler, and the heating water outlet 141 is used to connect to the heating pipeline water inlet system for indoor use. In this way, the water outlet valve 100 can be applied to the water outlet operations of both the wall-mounted boiler bathroom system and the heating system.

[0075] The present utility model also proposes a wall-mounted boiler, which includes a control member 200 and a water outlet valve 100. The specific structure of the water outlet valve 100 refers to the above embodiment. Since this wall-mounted boiler adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here. Among them, the control member 200 is electrically connected to the flow rate adjustment assembly 20 of the water outlet valve 100.

[0076] Optionally, the wall-mounted boiler further includes a bathroom module and a heating module. The bathroom module is connected to the high-temperature water inlet flow channel 11, and the heating module is connected to the heating flow channel 14.

[0077] In the above embodiment, the wall-mounted boiler further includes a burner, a heat exchanger, and a water circulation system. Specifically, the burner is responsible for burning gas to generate heat energy, the heat exchanger transfers the heat energy generated by combustion to water or air, and the water circulation system is responsible for circulating the heat-exchanged water through pipelines to the heating module or the bathroom module to achieve the heating function and the bathroom function.

[0078] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
