Description

Technical Field

The water system is mainly used to control the flow direction of the water, so that the wall-mounted boiler can switch between floor heating state and bathroom state as needed.

[0003] The existing wall-mounted boiler water system, such as a low-position side-insertion integrated water circuit disclosed in the authorization announcement number CN215809268U, includes a plate heat exchanger, a water inlet module and a water outlet module. The plate heat exchanger is provided with a first exchange pipe and a second exchange pipe. The water inlet module and the water outlet module are connected through the plate heat exchanger. The water inlet module includes a water pump and an integrated interface component. The water outlet module includes a multi-channel switching integrated block, a one-way reflux component and a channel switching component. The flow direction of the water circuit is controlled by cooperating with the water inlet module and the water outlet module to switch the wall-mounted boiler to the floor heating state or the bathroom state.

[0004] When the wall-mounted boiler is switched to the bathroom state, the water inlet module and the water outlet module cooperate to control the water path to form a circulating water flow and a bathroom water flow. The circulating water flow and the bathroom water flow flow through the first exchange pipe and the second exchange pipe respectively and generate heat exchange, so that the bathroom water flow is heated and flows out for use.

[0005] However, when the water pressure and flow rate of the bathroom water flow are low and the water temperature of the circulating water flow is high, excessive heat exchange occurs between the circulating water flow and the bathroom water flow, causing the bathroom water flow to be heated too high, thereby causing discomfort to the user; therefore, further improvements can be made.

[0009] Optionally, the transmission mechanism includes a fixed component, a movable component, a transmission component, a first sealing component and a second sealing component, the fixed component is fixedly arranged on the valve body module, the first sealing component is connected between the fixed component and the valve body module, the movable component is threadedly connected to the fixed component, the movable component is slidably engaged with the output end of the servo module, so that the servo module is used to drive the movable component to rotate, and the movable component moves linearly relative to the fixed component and the servo module during the rotation process, one end of the transmission component is connected to the movable component, the end of the transmission component away from the movable component is penetrated by the fixed component, and the end of the transmission component away from the movable component is connected to the adjusting mechanism, and the second sealing component is connected between the transmission component and the fixed component.

[0011] Through the above technical solution, when the servo module is driven by external power, the output end of the servo module drives the movable component to rotate through the clamping column and the clamping groove, and the movable component realizes linear up and down movement relative to the fixed component through threaded cooperation. At the same time, the movable component moves linearly up and down relative to the output end of the servo module. In the process of linear up and down movement of the movable component, the clamping limit of the first limit mechanism and the second limit mechanism is used to drive the transmission component and the plug mechanism to move linearly up and down synchronously, that is, the output end of the transmission mechanism has the function of moving up and down when driven by external power.

[0012] Optionally, the adjusting mechanism includes a piston assembly and a third sealing ring, the piston assembly is provided with a third sealing groove, the third sealing ring is embedded in the third sealing groove, and the third sealing ring and the first water inlet channel are both provided with matching abutment slopes; the movable assembly and the piston assembly are both provided with connecting holes, the two ends of the transmission assembly are respectively penetrated through two groups of connecting holes, and the transmission assembly is provided with a first limiting mechanism at corresponding positions on both sides of the movable assembly, and the transmission assembly is provided with a second limiting mechanism at corresponding positions on both sides of the piston assembly; the valve body module is provided with a guide assembly at a corresponding position below the piston assembly, and the transmission assembly is penetrated through the guide assembly.

[0013] Through the above technical scheme, when the output end of the transmission mechanism drives the adjusting mechanism to move downward, the abutting slope of the third sealing ring is squeezed with the abutting slope of the first water inlet channel, so that the adjusting mechanism is blocked in the first water inlet channel, so that cold water cannot be injected into the first water inlet channel; when the output end of the transmission mechanism drives the adjusting mechanism to move upward, the abutting slope of the third sealing ring is separated from the abutting slope of the first water inlet channel, so that the adjusting mechanism is separated from the first water inlet channel, so that cold water can be injected into the first water inlet channel.

[0016] Optionally, the first limiting mechanism includes two groups of elastic retaining springs, both groups of the elastic retaining springs are clamped and arranged on the transmission assembly, and the two groups of the elastic retaining springs are respectively located on the upper and lower sides of the movable assembly; the second limiting mechanism includes a mounting block, a fixed magnetic component, a follower magnetic component and a buffer spring, the mounting block is fixedly arranged on the transmission assembly and is located on the upper side of the piston assembly, the fixed magnetic component is fixedly arranged on the transmission assembly and is located on the lower side of the piston assembly, the follower magnetic component is fixedly arranged on the piston assembly, and the buffer spring is connected between the mounting block and the piston assembly, so that the piston assembly always has a tendency to move downward until the fixed magnetic component and the follower magnetic component are in fit.

[0017] Through the above technical solution, when the servo module drives the transmission assembly upward as an external power, the transmission assembly drives the adjustment mechanism upward through the second limiting mechanism until it is separated from the first water inlet channel. At this time, the buffer spring pushes the piston assembly downward until the fixed magnetic part and the follower magnetic part are in contact with each other to form a magnetic effect. Under the dual effects of elastic force and magnetic attraction, the piston assembly can have good stability and is not prone to up and down shaking, so that the gap size between the adjustment mechanism and the first water inlet channel and the corresponding cold water flow rate have good stability; conversely, when the servo module drives the transmission assembly downward as an external power, the transmission assembly drives the adjustment mechanism downward through the second limiting mechanism until it is blocked in the first water inlet channel. At this time, if the servo module runs excessively and causes the transmission assembly to move downward excessively, the fixed magnetic part and the follower magnetic part are separated and the buffer spring is compressed, so that the transmission assembly can continue to move downward relative to the adjustment mechanism, and excessive extrusion and damage between the third sealing ring of the adjustment mechanism and the first water inlet channel are avoided as much as possible to ensure the stability of the structure.

[0018] Optionally, the valve body module is provided with a stirring assembly at a corresponding position inside the first water inlet channel, and the stirring assembly is slidably engaged with the transmission assembly. The valve body module is provided with a rotating assembly at a corresponding position below the first water inlet channel, and when the movable assembly drives the transmission assembly to move linearly to a predetermined position through the first limiting mechanism, the rotating assembly drives the stirring assembly to rotate through the transmission assembly.

[0019] Through the above technical solution, Optionally, the stirring assembly includes a sliding ring and a stirring frame, the sliding ring is slidably sleeved on the transmission assembly, the sliding ring is fixedly provided with a transmission block, the transmission assembly is provided with a transmission groove slidably adapted to the transmission block, and the stirring frame is fixedly provided on the sliding ring; the rotating assembly includes an installation chamber, a rotating member, a guide cylinder, a thrust rod and a thrust spring, the installation chamber is fixedly provided on the first water inlet channel, the transmission assembly extends to the installation chamber at one end away from the movable assembly, the rotating member is fixedly provided on the one end of the transmission assembly away from the movable assembly, and the rotating member is fixed along its axis Four groups of inclined wedge blocks are fixedly arranged, the guide cylinder is fixedly arranged in the installation chamber, and eight groups of avoidance grooves are arranged along the axis of the guide cylinder, the avoidance grooves are plugged and matched with the inclined wedge blocks, and an inclined wedge surface is arranged between two adjacent groups of the avoidance grooves, the thrust rod is slidably arranged in the guide cylinder, and eight groups of guide teeth are arranged along the axis of the thrust rod, the unfolded surface of the guide teeth is an isosceles triangle structure, and the tooth tips of the guide teeth are aligned with the center of the avoidance groove; the thrust spring is connected between the installation chamber and the thrust rod, so that the thrust rod always has a tendency to move upward until the guide teeth exceed the inclined wedge surface.

[0020] Through the above technical scheme, during the rotation of the transmission component, the transmission block and the transmission groove cooperate to drive the stirring frame to rotate, so that the stirring frame cleans the inner wall of the first water inlet channel to avoid the attachment of excessive impurities as much as possible; since the water flow velocity in each area of ​​the gap between the adjustment mechanism and the first water inlet channel is different, the impurities in the water flow have different wear rates on each area of ​​the third sealing ring. In addition, by driving the third sealing ring to rotate through the second limiting mechanism during the rotation of the transmission component, the various areas of the third sealing ring can be continuously rotated and switched to cope with wear, thereby reducing the overall wear rate of the third sealing ring.

[0024] Through the above technical solution, under the special condition that the cold water pressure output by the faucet is relatively small, even if the power of the burner is reduced to the minimum value, the temperature of the hot water output from the bathroom is too high due to the slow flow rate of cold water in the basic water channel structure and excessive heat exchange with the hot water; at this time, the sensor module detects that the temperature of the hot water output from the mixed water outlet channel is higher than the preset temperature value and feeds back the situation to the control module, the control module controls the servo module to drive the output end of the transmission mechanism to move upward, the output end of the transmission mechanism drives the adjustment mechanism to move upward to separate from the first water inlet channel, so that part of the cold water from the faucet flows through the connecting pipe and the first water inlet channel to the second water inlet channel in sequence, and the cold water of this part is mixed with the hot water and then output from the mixed water outlet channel, so as to reduce the temperature of the hot water in the bathroom; at this time, the control module controls the operation of the servo module according to the real-time monitoring of the sensor module, so that the gap between the adjustment mechanism and the first water inlet channel and the corresponding cold water flow rate are kept in a reasonable range, so as to avoid the hot water temperature output from the mixed water outlet channel being too high or too low to cause discomfort to the user.

[0043] In the above, the regulating mechanism 21 moves downward to block the first water inlet channel 11 or moves upward to be separated from the first water inlet channel 11, which is specifically manifested as follows in this embodiment: The adjusting mechanism 21 specifically includes a piston assembly 211 and a third sealing ring 212; wherein, the piston assembly 211 is located at the connection between the first water inlet channel 11 and the valve body module 1, a connecting hole for the transmission assembly 223 to pass through is arranged at the center of the piston assembly 211, and two groups of elastic retaining springs of the second limiting mechanism 6 are respectively located at the upper and lower sides of the piston assembly 211, a third sealing groove is arranged on the outer periphery of the piston assembly 211, the third sealing ring 212 is embedded in the third sealing groove, and the third sealing ring 212 and the first water inlet channel 11 are both provided with matching abutment slopes.

[0044] When the output end of the transmission mechanism 22 drives the adjusting mechanism 21 to move downward, the abutting slope of the third sealing ring 212 is squeezed with the abutting slope of the first water inlet channel 11, so that the adjusting mechanism 21 is blocked in the first water inlet channel 11, so that cold water cannot be injected into the first water inlet channel 11; when the output end of the transmission mechanism 22 drives the adjusting mechanism 21 to move upward, the abutting slope of the third sealing ring 212 is separated from the abutting slope of the first water inlet channel 11, so that the adjusting mechanism 21 is separated from the first water inlet channel 11, so that cold water can be injected into the first water inlet channel 11.

[0045] In this embodiment, a guide assembly 7 is provided at a corresponding position of the valve body module 1 below the piston assembly 211. The guide assembly 7 is a guide block, which is fixedly arranged on the inner wall of the first water inlet channel 11. The guide block is provided with a guide hole adapted to the transmission assembly 223, and the transmission assembly 223 is arranged through the guide assembly 7.

[0046] When the regulating mechanism 21 is separated from the first water inlet channel 11 to inject cold water, the guide assembly 7 can improve the stability of the transmission assembly 223 and the piston assembly 211, and try to avoid the piston assembly 211 from shaking and making noise due to the impact of water flow.

[0047] In this embodiment, the mixed water outlet channel 13 includes a first mixing section 131, a second mixing section 132 and a third mixing section 133 which are connected in sequence; wherein the front end of the first mixing section 131 is connected to the side wall of the valve body module 1, the second water inlet channel 12 is connected to the middle of the first mixing section 131, the sensing end of the sensor module 4 is arranged in the middle of the third mixing section 133, the angle between the first mixing section 131 and the second mixing section 132 is 90 degrees, and the second mixing section 132 and the third mixing section 133 are arranged in parallel.

[0048] After the cold water injected into the first water inlet channel 11 and the hot water injected into the second water inlet channel 12 converge in the first mixing section 131, the cold water and the hot water flow through the second mixing section 132 and the third mixing section 133 in turn and are output. In the process of flowing from the first mixing section 131 to the second mixing section 132 and from the second mixing section 132 to the third mixing section 133, the cold water and the hot water can be mixed more fully, thereby improving the uniformity of the hot water output from the mixed water outlet channel 13.

[0049] Implementation principle: Under normal conditions, hot water flows through the second water inlet channel 12 and the mixed water outlet channel 13 in sequence for output; When the temperature of the hot water output from the mixed water outlet channel 13 is too high, the sensor module 4 detects that the temperature of the hot water output from the mixed water outlet channel 13 is higher than the preset temperature value and feeds back the situation to the control module. The control module controls the output end of the servo module 3 to rotate forward. The output end of the servo module 3 drives the movable component 222 to rotate forward through the clamping column 228 and the clamping groove 229. The movable component 222 moves upward in a straight line relative to the fixed component 221 through threaded cooperation. The movable component 222 also moves upward in a straight line relative to the output end of the servo module 3. During the process of the movable component 222 moving upward in a straight line, the piston is driven by the clamping limit of the first limit mechanism 5 and the second limit mechanism 6. The component 211 moves upward in a straight line synchronously, so that the abutting slope of the third sealing ring 212 is separated from the abutting slope of the first water inlet channel 11, so that the regulating mechanism 21 is separated from the first water inlet channel 11, so that the first water inlet channel 11 can be injected with cold water, and the cold water injected into the first water inlet channel 11 and the hot water injected into the second water inlet channel 12 are mixed and outputted from the mixed water outlet channel 13. At this time, the control module controls the operation of the servo module 3 according to the real-time monitoring of the sensor module 4, so that the gap between the regulating mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate are maintained in a reasonable range, so as to avoid the hot water temperature outputted from the mixed water outlet channel 13 being too high and causing discomfort to the user; When the hot water output from the mixed water outlet channel 13 is too cold, the output end of the servo module 3 drives the movable component 222 to rotate in the opposite direction through the clamping column 228 and the clamping groove 229, so that the abutting inclined surface of the third sealing ring 212 can be squeezed with the abutting inclined surface of the first water inlet channel 11, thereby realizing that the regulating mechanism 21 is blocked in the first water inlet channel 11, so that the first water inlet channel 11 cannot be injected with cold water.

[0050] Embodiment 2: The difference between this embodiment and the first embodiment is that this embodiment is further provided with a buffer structure, which is used to buffer the overload of the piston assembly 211. This embodiment is also provided with a cleaning structure, which is used to clean the first water inlet channel 11 in real time.

[0051] In the above, the buffer structure is used to buffer the piston assembly 211 from overload, which is specifically manifested as follows in this embodiment: Reference Figure 6-7 The first limiting mechanism 5 also includes two groups of elastic retaining springs in the prior art, and the two groups of elastic retaining springs are both clamped and arranged in the retaining spring grooves reserved in the transmission component 223, and the two groups of elastic retaining springs of the first limiting mechanism 5 are respectively located on the upper and lower sides of the movable component 222, so that the movable component 222 can drive the transmission component 223 to move up and down synchronously in the process of moving up and down in a straight line; the second limiting mechanism 6 specifically includes a mounting block 61, a fixed magnetic suction member 62, a follower magnetic suction member 63 and a buffer spring 64, the mounting block 61 is fixedly arranged on the transmission component 223, and the mounting block 61 is located at the piston On the upper side of the component 211, the fixed magnetic component 62 and the follower magnetic component 63 both use permanent magnets. The fixed magnetic component 62 is fixedly set on the transmission component 223, and the fixed magnetic component 62 is located on the lower side of the piston component 211. The follower magnetic component 63 is fixedly set at the bottom of the piston component 211. The buffer spring 64 adopts a compression spring structure, and the two ends of the buffer spring 64 are respectively fixedly connected between the mounting block 61 and the piston component 211. Under the elastic force of the buffer spring 64, the piston component 211 always has a tendency to move downward until the fixed magnetic component 62 and the follower magnetic component 63 are in contact with each other.

[0052] When the servo module 3 acts as an external power to drive the transmission component 223 to move upward, the transmission component 223 drives the adjustment mechanism 21 to move upward through the second limit mechanism 6 until it is separated from the first water inlet channel 11. At this time, the buffer spring 64 pushes the piston component 211 to move downward until the fixed magnetic element 62 and the follower magnetic element 63 fit together to form a magnetic attraction effect. Under the dual effects of elastic force and magnetic attraction, the piston component 211 can have good stability and is not prone to up and down shaking, so that the gap size between the adjustment mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate have good stability; In other words, when the servo module 3 acts as an external power to drive the transmission component 223 to move downward, the transmission component 223 drives the adjustment mechanism 21 to move downward through the second limiting mechanism 6 until it is blocked in the first water inlet channel 11. At this time, if the servo module 3 over-operates and causes the transmission component 223 to move excessively downward, the fixed magnetic component 62 and the follower magnetic component 63 will be disengaged and the buffer spring 64 will be compressed, so that the transmission component 223 can continue to move downward relative to the adjustment mechanism 21, thereby avoiding excessive extrusion and damage between the third sealing ring 212 of the adjustment mechanism 21 and the first water inlet channel 11 to ensure the stability of the structure. In addition, since the squeezing force between the adjusting mechanism 21 and the first water inlet channel 11 is the sum of the elastic force and the magnetic attraction force, when the transmission component 223 moves excessively downward, the fixed magnetic attraction component 62 and the follower magnetic attraction component 63 are disengaged, and the buffer spring 64 is compressed, the magnetic attraction force exerted on the adjusting mechanism 21 decreases as the transmission component 223 moves downward, and the elastic force exerted on the adjusting mechanism 21 increases as the transmission component 223 moves downward, and the fluctuation of the sum of the elastic force and the magnetic attraction force is relatively small, that is, as the transmission component 223 moves excessively downward, the fluctuation of the squeezing force between the adjusting mechanism 21 and the first water inlet channel 11 is relatively small, thereby avoiding excessive squeezing and damage between the third sealing ring 212 of the adjusting mechanism 21 and the first water inlet channel 11 as much as possible, thereby ensuring the stability of the structure.

[0053] In the above, the cleaning structure is used to clean the first water inlet channel 11 in real time, which is specifically manifested as follows in this embodiment: A stirring assembly 8 is provided at a corresponding position of the valve body module 1 inside the first water inlet channel 11, and the stirring assembly 8 is slidably engaged with the transmission assembly 223. A rotating assembly 9 is provided at a corresponding position of the valve body module 1 below the first water inlet channel 11, and when the movable assembly 222 drives the transmission assembly 223 to move linearly to a predetermined position through the first limiting mechanism 5, the rotating assembly 9 drives the stirring assembly 8 to rotate through the transmission assembly 223.

[0054] The stirring assembly 8 specifically includes a sliding ring 81 and a stirring frame 82; wherein the sliding ring 81 is a circular ring structure, which is slidably mounted on the transmission assembly 223, a transmission block 83 is fixedly arranged on the inner periphery of the sliding ring 81, and a transmission groove 84 slidably adapted to the transmission block 83 is arranged on the outer periphery of the transmission assembly 223, the stirring frame 82 is fixedly arranged on the sliding ring 81, and the stirring frame 82 is fitted with the inside of the first water inlet channel 11, and under the support of the stirring frame 82, the sliding ring 81 is fitted with the bottom of the guide assembly 7.

[0055] Reference Figure 8-10 The rotating assembly 9 specifically includes an installation chamber 91, a rotating member 92, a guide cylinder 93, a thrust rod 94 and a thrust spring 95; wherein the installation chamber 91 is fixedly arranged at the bottom of the first water inlet channel 11, and the valve body module 1, the first water inlet channel 11 and the installation chamber 91 are coaxially arranged, the bottom end of the transmission assembly 223 passes through the fourth sealing ring reserved at the bottom of the first water inlet channel 11 and extends to the installation chamber 91, the rotating member 92 is fixedly arranged at the bottom of the transmission assembly 223, and the rotating member 9 Four groups of inclined wedges 96 are evenly and fixedly arranged along the axis of the outer circumference. The four groups of inclined wedges 96 are all vertical long strip structures, and the bottom ends of the four groups of inclined wedges 96 are 45-degree inclined surfaces; the guide cylinder 93 is a cylindrical structure, and the inner diameter of the guide cylinder 93 is larger than the outer diameter of the rotating member 92. The guide cylinder 93 is fixedly arranged in the installation chamber 91. The guide cylinder 93 is evenly and fixedly arranged along the axis of the guide cylinder 93. Eight groups of avoidance grooves 97 are plugged and matched with any inclined wedge 96, that is, the rotating member 92 is inserted into When the guide tube 93 is pushed, the four groups of inclined wedge blocks 96 can be inserted into the four groups of avoidance grooves 97. In addition, an inclined wedge surface 98 is provided between two adjacent groups of avoidance grooves 97. The inclined wedge surface 98 is also a 45-degree inclined surface. The thrust rod 94 is a hollow round rod structure, and the inner diameter of the guide tube 93 coincides with the outer diameter of the thrust rod 94. The thrust rod 94 is slidably arranged on the guide tube 93. Eight groups of protrusions are provided on the outer periphery of the thrust rod 94. The eight groups of protrusions are respectively slidably arranged in the eight groups of avoidance grooves 97 to limit the thrust rod 94. The thrust rod 94 can only move up and down due to the rotational freedom. Eight groups of guide teeth 99 are evenly and fixedly arranged on the top of the thrust rod 94 along its axis. The unfolded surface of the guide teeth 99 is a right-angled isosceles triangle structure, and the tips of the eight groups of guide teeth 99 are respectively aligned with the centers of the eight groups of avoidance grooves 97. The thrust spring 95 is a compression spring structure. The thrust spring 95 is connected between the installation chamber 91 and the thrust rod 94, so that the thrust rod 94 always has the tendency to move upward until the guide teeth 99 exceed the inclined wedge surface 98. It is worth mentioning that the sum of the thickness of the guide teeth 99 and the thickness of the guide tube 93 mentioned above is equal to the thickness of the inclined wedge block 96, that is, the inclined wedge block 96 can contact the tips of the guide teeth 99 and the inclined wedge surface 98 at the same time during the movement.

[0056] In the initial state, the inclined wedge block 96 is staggered with the avoidance groove 97; when the transmission assembly 223 moves downward to a predetermined position (specifically, since the friction between the adjustment mechanism 21 and the first water inlet channel 11 will affect the rotation of the transmission assembly 223, the predetermined position means that there is still a gap between the adjustment mechanism 21 and the first water inlet channel 11), the inclined wedge block 96 first contacts the guide tooth 99, and the inclined wedge block 96 is guided to the bottom of the guide tooth 99, and the transmission assembly 223 continues to move downward, and the inclined wedge block 96 then contacts the inclined wedge surface 98, and the inclined wedge block 96 is guided to completely enter the avoidance groove 97, so that the thrust rod 94 is pressed against The thrust spring 95 is compressed; when the transmission assembly 223 moves upward to a predetermined position (specifically, since the friction between the adjusting mechanism 21 and the first water inlet channel 11 will affect the rotation of the transmission assembly 223, the predetermined position means that there is still a gap between the adjusting mechanism 21 and the first water inlet channel 11), the rotating member 92 moves upward synchronously, the inclined wedge block 96 completely withdraws from the avoidance groove 97, and the thrust rod 94 moves upward under the action of the thrust spring 95 until the guide tooth 99 exceeds the inclined wedge surface 98. At this time, the guide tooth 99 guides the inclined wedge block 96 for a second time, so that the inclined wedge block 96 is restored to be offset from the avoidance groove 97, and the cycle is repeated.

[0057] In the above, during the process that the inclined wedge block 96 is guided to the bottom of the guide tooth 99, the inclined wedge block 96 is guided to completely enter the avoidance groove 97, and the guide tooth 99 guides the inclined wedge block 96 for the second time, the rotating member 92 will drive the transmission assembly 223 to rotate in the same direction, and the overall rotation angle is 45 degrees, that is, 1 / 8 of a circle; at this time, during the rotation of the transmission assembly 223, the transmission block 83 and the transmission groove 84 cooperate to drive the stirring frame 82 to rotate, so that the stirring frame 82 cleans the inner wall of the first water inlet channel 11 and tries to avoid the attachment of excessive impurities; due to the difference in water flow velocity in each area of ​​the gap between the adjustment mechanism 21 and the first water inlet channel 11, the impurities in the water flow wear different areas of the third sealing ring 212 at different speeds. In addition, by driving the third sealing ring 212 to rotate through the second limiting mechanism 6 during the rotation of the transmission assembly 223, the various areas of the third sealing ring 212 can be continuously rotated and switched to cope with wear, thereby reducing the overall wear speed of the third sealing ring 212.

[0058] The application also discloses an integrated water system with a servo water mixing valve.

[0059] Reference Figure 1-3, an integrated water channel system with a servo mixing valve, including a basic water channel structure 10 and the above-mentioned servo mixing valve, wherein the basic water channel structure 10 is an ordinary water channel structure in the prior art, such as a low-position side-inserted integrated water channel disclosed by the applicant in CN215809268U, which will not be repeated here. The basic water channel structure 10 is provided with a bathroom water inlet interface 101 and a bathroom water outlet interface 102. The second water inlet channel 12 of the servo mixing valve is connected to the bathroom water outlet interface 102, so that the second water inlet channel 12 is connected to the mixing water outlet channel 13 and is used to input hot water. The first water inlet channel 11 of the servo mixing valve is connected to the bathroom water inlet interface 101 through a preset connecting pipe 103, so that the first water inlet channel 11 is connected to the bottom of the valve body module 1 and is used to input cold water.

[0060] In the application of the wall-mounted boiler water system, under normal conditions, the hot water heated by the burner circulates in the basic water channel structure 10, and the cold water output by the faucet flows in the basic water channel structure 10 and generates heat exchange with the hot water, thereby realizing the output of bathroom hot water; In the special condition where the cold water pressure outputted by the faucet is low, even if the power of the burner is reduced to the minimum value, the temperature of the hot water outputted from the bathroom is too high due to the slow flow rate of the cold water in the basic water channel structure 10 and the excessive heat exchange with the hot water; At this time, when the sensor module 4 detects that the temperature of the hot water output by the mixed water outlet channel 13 is higher than the preset temperature value, it feeds back the situation to the control module, and the control module controls the servo module 3 to drive the output end of the transmission mechanism 22 to move upward, and the output end of the transmission mechanism 22 drives the adjustment mechanism 21 to move upward until it is separated from the first water inlet channel 11, so that part of the cold water from the faucet passes through the connecting pipe 103 and the first water inlet channel 11 to flow to the second water inlet channel 12 in turn, and this part of the cold water is mixed with the hot water and then output from the mixed water outlet channel 13, so as to reduce the temperature of the bathroom hot water; at this time, the control module controls the operation of the servo module 3 according to the real-time monitoring of the sensor module 4, so that the gap between the adjustment mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate are maintained in a reasonable range, so as to avoid the hot water temperature output by the mixed water outlet channel 13 being too high or too low to cause discomfort to the user.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
