Description

Technical Field

[0001] The utility model relates to the technical field of automatic temperature control systems for faucets, in particular to a constant temperature controller for controlling water temperature, which is particularly suitable for use in shower systems. Background Art

[0002] At present, the intelligent faucet has poor stability in terms of realizing intelligence, and has not well combined intelligent technology with functional experience, ignoring the convenience and stability of using intelligent faucets. At present, the intelligent valve control systems on the market are basically controlled by a flat-opening water mixing valve core. For example, a Chinese invention patent application with application number CN202210152317.1 (publication number CN114484009A) discloses "a control valve and its control method" and discloses such a flat-opening water mixing valve core that can realize intelligent control, including a valve body and a main control board, a valve core for controlling the water outlet temperature and the water outlet flow rate is arranged in the valve body, an execution unit 1 and an execution unit 2 are arranged on the valve body, a detection unit 1 for detecting the water flow temperature and a detection unit 2 for detecting the water flow pressure are arranged on the valve body, the main control board can receive the signal of the detection unit 1 and drive the valve core to control the water outlet flow through the execution unit 1, and the main control board can receive the signal of the detection unit 2 and drive the valve core to control the water outlet temperature through the execution unit 2.

[0003] The above solution has the following defects:

[0004] 1. Due to the large fluctuations in hot water pressure or hot water temperature in most users' usage scenarios, the valve core needs to rotate continuously to adjust the temperature. The valve core does not react quickly to water pressure fluctuations. Due to the water pressure difference, the fluctuation range of water output becomes larger, and the water temperature will fluctuate in a certain period of time, affecting the experience.

[0005] 2. This type of intelligent control box currently has only one water outlet, which is not convenient for use in a shower system. If it is to be used in a shower system, an additional water distribution faucet needs to be installed after the water outlet, resulting in a more dispersed control part.

[0006] 3. It has only one temperature sensor, and it is set at the end. It can only compare the outlet water temperature with the set temperature. It may also cause the outlet water temperature to be extremely unstable. The outlet water temperature will be too high or too low, and the user experience will be poor. Since the water inlet pressure and flow rate are unknown, multiple adjustments are required to reach the set temperature.

[0007] 4. This type of intelligent control box currently has only one water outlet, which is not convenient for use in a shower system. If it is to be used in a shower system, an additional water distribution faucet needs to be installed after the water outlet, resulting in a more dispersed control part.

[0008] 5. The water inlet flow of a single channel can only be controlled in some areas.

[0009] Therefore, the automatic temperature control module of the existing faucet needs further improvement. Utility Model Content

[0010] The first technical problem to be solved by the utility model is to provide a thermostatic controller for controlling water temperature with reasonable structure, little influence by water inlet pressure fluctuation and capable of automatically adjusting water outlet temperature, in view of the current status of the prior art.

[0011] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a thermostatic controller for controlling water temperature, characterized in that: it includes a valve seat, the valve seat has a cold water inlet channel, a hot water inlet channel, a first valve core installation cavity, a second valve core installation cavity, a cold water outflow channel, a hot water outflow channel, a mixing water cavity, a third valve core installation cavity and a mixed water outflow channel, the mixing water cavity is connected to the mixed water outflow channel; a first flow regulating valve core is installed in the first valve core installation cavity, the cold water inlet channel is connected to the first water inlet end of the first flow regulating valve core, the first water outlet end of the first flow regulating valve core is connected to the cold water outflow channel, and the first regulating valve core is installed in the first valve core installation cavity. The first movable valve plate of the flow valve core is driven to rotate by the first motor to adjust the cold water flow; the second flow regulating valve core is installed in the second valve core installation cavity, the hot water inlet channel is connected with the second water inlet end of the second flow regulating valve core, the second water outlet end of the second flow regulating valve core is connected with the hot water outflow channel, and the second movable valve plate of the second flow regulating valve core is driven to rotate by the second motor to adjust the hot water flow; the balancing valve core is installed in the third valve core installation cavity, the cold water outflow channel is connected with the cold water inlet of the balancing valve core, the hot water outflow channel is connected with the hot water inlet of the balancing valve core, and the cold water outlet and hot water outlet of the balancing valve core are both connected with the mixing water chamber.

[0012] Further improvement, there are multiple mixed water outflow channels, the valve seat has a fourth valve core installation cavity, a water diversion valve core is installed in the fourth valve core installation cavity, the water outlet of the mixed water cavity is connected to the third water inlet of the water diversion valve core, and the multiple third water outlets of the water diversion valve core are connected to the mixed water outflow channels accordingly, and the third movable valve plate of the water diversion valve core is driven to rotate by the third motor so that the third water inlet is selectively connected to one of the third water inlet. After the hot and cold water are mixed in the mixed water cavity, they flow to the water diversion valve core, and the water is directed to one of the mixed water outflow channels through the water diversion valve core. The corresponding mixed water outflow channel is connected to the corresponding water outlet structure (shower, faucet, overhead spray) in the shower system, and there is no need to set up an additional water diversion valve outside the module. Therefore, this module has a compact structure and good integrity, and is particularly suitable for shower systems.

[0013] As an improvement, a manual switch valve core is installed in the water mixing chamber to manually control the water outlet of the water mixing chamber. The setting of the manual switch valve core allows the total water outlet to be manually closed when the motor is damaged, making it more user-friendly.

[0014] As an improvement, a water flow generator is also installed in the water mixing chamber, and the manual switch valve core is arranged below or above the water flow generator. The water flow generator is a structure that uses water flow to generate electricity. It is a prior art. In this solution, the water flow generator is arranged in the water mixing chamber. The water flows flowing in from both sides jointly drive the impeller of the water flow power generation component to rotate, and the power generation efficiency is higher. The electric energy generated by the water flow power generation component can be supplied to the display screen, and can also be supplied to the battery or other electrical components.

[0015] Preferably, the manual switch valve core is a ball valve, the fourth water inlet end of the manual switch valve core is arranged at the bottom, the fourth water outlet end is arranged at the top, and the manual switch valve core is inserted into the mixing water chamber laterally. The ball valve can make the water passage conduction a straight up and down structure, reduce energy loss, and make the water outlet pressure higher. Alternatively, the fourth water inlet end of the manual switch valve core is arranged at the bottom, the fourth water outlet end is arranged at the side, the manual switch valve core is inserted into the mixing water chamber from top to bottom, and is fixed in the mixing water chamber by threaded connection to the fourth gland of the mixing water chamber.

[0016] In order to quickly and accurately adjust the water outlet temperature automatically, further improvements are made, including a first flow sensor, arranged in the cold water inlet channel to detect the flow of cold water; a second flow sensor, arranged in the hot water inlet channel to detect the flow of hot water; a first temperature sensor, arranged in the hot water outflow channel to detect the water temperature of hot water; a second temperature sensor, arranged in the mixing water chamber to detect the water temperature of mixed water. The flow rates of cold water and hot water are measured by two flow sensors, and the temperature of cold water is basically constant. The temperature of hot water is detected by the first temperature sensor, and the data of the two detected flow rates and the temperature of hot water are sent to the information control module. The information control module will calculate the flow rates and the temperature of hot water based on the model (the model knows how much flow rate of hot water and how much flow rate of cold water are mixed to obtain mixed water with the corresponding flow rate and temperature), that is, it roughly knows how much angle range the movable valve plates of the two flow regulating valve cores need to rotate respectively so that the mixed water can reach the set temperature and flow rate. At this time, the movable valve plate of the flow regulating valve core will rotate to an angle in advance (this angle is close to the angle that needs to be rotated to in the end), and finally, it will be compared with the water temperature signal of the mixed water measured by the second temperature sensor. The information control module sends a final signal to the two motor control modules, and the movable valve plate of the flow regulating valve core can quickly rotate to the correct angle. Because its response speed is very fast, the problem of the mixed water outlet being hot and cold will be significantly improved.

[0017] Although the cold water temperature does not change much, there is still a clear difference between winter and summer. In order to automatically adjust the outlet water temperature more accurately, further improvements are made, including a third temperature sensor, which is installed in the cold water outflow channel to detect the temperature of the cold water. Combined with the cold water temperature signal detected by the third temperature sensor, the cold water temperature data is sent to the information control module together with the two flow rates and hot water temperature data mentioned above, so that it can be clearer how much the movable valve plates of the two flow regulating valve cores need to rotate respectively, and the movable valve plate of the flow regulating valve core will rotate in advance to an angle closer to the set temperature.

[0018] In order to make the layout of each flow channel reasonable, as a preferred layout, the above-mentioned cold water outflow channel, hot water outflow channel, mixed water outflow channel, mixed water chamber, third valve core installation chamber and fourth valve core installation chamber are all located between the first valve core installation chamber and the second valve core installation chamber, the first valve core installation chamber and the cold water inlet flow channel are coaxially arranged, the second valve core installation chamber and the hot water inlet flow channel are coaxially arranged, and the axes of the cold water inlet flow channel and the hot water inlet flow channel are parallel and the mouth ends are facing downward, which is conducive to the connection of the cold water inlet pipe, the hot water inlet pipe and the outlet pipe with this module. The connection direction of each water pipe is connected from bottom to top, and the pipe connection is more convenient and reasonable. The mouth ends of the first valve core installation chamber, the second valve core installation chamber and the fourth valve core installation chamber face upward, and the mouth end of the third valve core installation chamber faces downward. Because the water inlet flow channel and the corresponding valve core installation chamber are coaxially arranged and connected from top to bottom, it is conducive to the molding of the product, and it is more convenient to pull the core of the mold during the manufacturing process.

[0019] In order to facilitate the forming of each flow channel in the valve seat, the cold water outflow channel and the hot water outflow channel are coaxially arranged transversely, the cold water outflow channel transversely penetrates the side wall of the first valve core installation cavity, and a first plug seal is provided at the perforation position of the side wall of the first valve core installation cavity, and the hot water outflow channel transversely penetrates the side wall of the second valve core installation cavity, and a second plug seal is provided at the perforation position of the side wall of the second valve core installation cavity; the third valve core installation cavity is arranged below the first axis, and the mixing water cavity and the fourth valve core installation cavity are arranged above the first axis. The cold water outflow channel and the hot water outflow channel correspondingly penetrate the first valve core installation cavity and the second valve core installation cavity and are located on the same axis, so that the cold water outflow channel and the hot water outflow channel can be formed by lateral core pulling.

[0020] In order to realize the convenient installation of the flow regulating valve core and the water diversion valve core, the first water inlet end of the above-mentioned first flow regulating valve core is arranged at the bottom, the first water outlet end is arranged at the side, and the first flow regulating valve core is inserted into the first valve core installation cavity from top to bottom; the second water inlet end of the second flow regulating valve core is arranged at the bottom, the second water outlet end is arranged at the side, and the second flow regulating valve core is inserted into the second valve core installation cavity from top to bottom; the third water inlet end of the water diversion valve core is arranged at the side, the third water outlet end is arranged at the bottom, and the water diversion valve core is inserted into the third valve core installation cavity from top to bottom. The flow regulating valve core and the water diversion valve core are both inserted into the valve core installation cavity from top to bottom, and then constrained by the pressure cover, which is very convenient to assemble, and the pressure cover also provides a suitable installation position for the motor. The pressure cover only needs to open a through hole for the output shaft of the power supply motor to pass through. After the output shaft of the motor passes through the through hole, it can be plugged with the valve stem of the flow regulating valve core, so that the motor can drive the valve stem to rotate, and then drive the rotation of the moving valve plate of the flow regulating valve core to achieve flow regulation.

[0021] Compared with the prior art, the advantages of the first technical solution of the utility model are as follows: the controller adopts two independent flow regulating valve cores and one balancing valve core to execute the control scheme. The two flow regulating valve cores are used to control the inflow of cold water and hot water respectively, and realize the control of water temperature and flow. In particular, when the water pressure of hot and cold water fluctuates, the flow of hot and cold water can be adjusted by moving the piston in the balancing valve core to ensure that the proportion of the two is mixed according to the preset ratio, which effectively solves the problem that the fluctuation range of water output becomes larger due to the water pressure difference, and the water temperature of the water output fluctuates in a certain period of time. In addition, the flow regulating valve cores are all controlled by motors, thus providing a basis for the automatic control of the shower system.

[0022] The second technical problem to be solved by the present invention is to provide a constant temperature shower system control module with a reasonable and compact structure, integrated with a water separation function, and capable of automatically adjusting the outlet water temperature in view of the current status of the prior art.

[0023] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a thermostatic controller for controlling water temperature, characterized in that: it includes a valve seat, the valve seat has a cold water inlet channel, a hot water inlet channel, a first valve core installation cavity, a second valve core installation cavity, a cold water outflow channel, a hot water outflow channel, a mixing water cavity, a fourth valve core installation cavity and a mixed water outflow channel, the cold water outflow channel and the hot water outflow channel are connected to the mixing water cavity, and there are multiple mixed water outflow channels; a first flow regulating valve core is installed in the first valve core installation cavity, the cold water inlet channel is connected to the first water inlet end of the first flow regulating valve core, the first water outlet end of the first flow regulating valve core is connected to the cold water outflow channel, and the first flow regulating valve core The first movable valve plate is driven by the first motor to rotate and adjust the cold water flow; the second flow regulating valve core is installed in the second valve core installation cavity, the hot water flow channel is connected with the second water inlet end of the second flow regulating valve core, and the second water outlet end of the second flow regulating valve core is connected with the hot water outflow channel, and the second movable valve plate of the second flow regulating valve core is driven by the second motor to rotate and adjust the hot water flow; the water diverter valve core is installed in the fourth valve core installation cavity, the water outlet end of the mixing chamber is connected with the third water inlet end of the water diverter valve core, and multiple third water outlet ends of the water diverter valve core are connected with each mixed water outflow channel accordingly, and the third movable valve plate of the water diverter valve core is driven by the third motor to rotate so that the third water inlet end is selected to be connected with one of the third water outlet ends.

[0024] Compared with the prior art, the second technical solution of the utility model has the following advantages: the controller uses two independent flow regulating valve cores and one water diversion valve core to execute the control scheme. The two flow regulating valve cores are used to control the inflow of cold water and hot water respectively, so as to realize the control of water temperature and flow. After the cold and hot water are mixed in the mixing water chamber, they flow to the water diversion valve core, and the water flows to one of the mixed water outflow channels through the water diversion valve core. The module integrates each valve core into a valve seat, and the corresponding mixed water outflow channel is connected to the corresponding water outlet structure (shower, faucet, overhead spray) in the shower system. There is no need to set up a water diversion valve outside the module. Therefore, the module has a compact structure and good integrity, and is particularly suitable for shower systems. In addition, both the flow regulating valve core and the water diversion valve core are controlled by motors, thus providing a basis for the automatic control of the shower system.

[0047] The balancing valve core 10 is installed in the third valve core installation cavity 1h, the cold water outflow channel 1e is connected to the cold water inlet 101 of the balancing valve core 10, the hot water outflow channel 1f is connected to the hot water inlet 102 of the balancing valve core 10, and the cold water outlet 103 and the hot water outlet 104 of the balancing valve core 10 are both connected to the mixing water cavity 1g.

[0048] There are multiple mixed water outflow channels 1i, and the valve seat 1 has a fourth valve core installation cavity 1j, in which a water-dividing valve core 6 is installed. The water outlet end of the mixing water cavity 1g is connected to the third water inlet end 61 of the water-dividing valve core 6, and multiple third water outlet ends 62 of the water-dividing valve core 6 are connected to each mixed water outflow channel 1i accordingly.

[0050] Of course, the directions of entry of cold water and hot water can be interchanged, that is, the cold water flow channel 1a can also enter hot water, and the hot water flow channel 1b can also enter cold water.

[0051] This controller uses two independent first flow regulating valve cores 2a, second flow regulating valve cores 2b and a balancing valve core 10 to execute the control scheme. The first flow regulating valve core 2a and the second flow regulating valve core 2b are used to control the inflow of cold water and hot water respectively, and realize the control of water temperature and flow. In particular, the setting of the balancing valve core 10 can adjust the flow of cold and hot water by moving the piston in the balancing valve core when the water pressure of hot and cold water fluctuates, ensuring that the proportion of the two is mixed according to the preset ratio, effectively solving the problem that the fluctuation range of the water output becomes larger due to the water pressure difference, and the water temperature of the water output will be hot and cold in a certain period of time. In addition, the flow regulating valve cores are all controlled by motors, thus providing a basis for the automatic control of the shower system.

[0052] This module further includes

[0053] The first flow sensor 4a is disposed in the cold water inlet passage 1a to detect the flow rate of cold water.

[0054] The second flow sensor 4b is disposed in the hot water inlet passage 1b to detect the flow rate of hot water.

[0055] The first temperature sensor 5a is disposed in the hot water outflow passage 1f to detect the water temperature of the hot water.

[0056] The second temperature sensor 5b is disposed in the water mixing chamber to detect the temperature of the mixed water.

[0057] like Figure 6 As shown, the first flow sensor 4a, the second flow sensor 4b, the first temperature sensor 5a, the second temperature sensor 5b and the third temperature sensor 5c are electrically connected to the information control module, and the motor control module is also electrically connected to the information control module. The information control module is also provided with a touch button for setting the outlet water temperature and starting or shutting down. It also includes a display module electrically connected to the information control module, and the display module is used to display the current water temperature, flow rate and the set outlet water temperature information.

[0058] like Figure 7As shown, after the user enables the start function through the information control module, the display module is started to display the lighted display information (current water temperature, cold water flow, hot water flow and set water outlet temperature information); the first flow sensor 4a is started to detect the cold water flow, and the cold water flow signal is transmitted to the information control module; the second flow sensor 4b is started to detect the hot water flow, and the hot water flow signal is transmitted to the information control module; the second temperature sensor 5b is started to detect the hot water temperature, and the hot water temperature signal is transmitted to the information control module. After the user sets the temperature to be reached and the required outflow flow of the mixed water in the control module, the information control module sends a signal to the motor control module according to the embedded model and algorithm, that is, it roughly knows how much angle range the movable valve plates of the first flow regulating valve core 2a and the second flow regulating valve core 2b need to rotate respectively so that the mixed water can reach the set temperature and flow. At this time, the movable valve plates of the first flow regulating valve core 2a and the second flow regulating valve core 2b will be rotated to an angle in advance driven by the first motor 3a and the second motor 3b (this angle is close to the angle to be rotated in the end), the third temperature sensor 5c detects the real-time water temperature of the mixed water, and transmits the real-time water temperature signal to the information control module for comparison, and the information control module sends a signal to the motor control module to control the first motor 3a and the second motor 3b to adjust the movable valve plates of the first flow regulating valve core 2a and the second flow regulating valve core 2b to quickly rotate to the correct angle (the temperature of the mixed water at this angle reaches the set temperature and flow), so its response speed is very fast, and the situation of the mixed water outlet being hot and cold will be significantly improved. After the hot and cold water are mixed in the water mixing chamber 1g, they flow to the water diversion valve core 6, which directs the water flow to one of the mixed water outflow channels 1i. This module integrates each valve core into a valve seat 1, and the corresponding mixed water outflow channel 1i is connected to the corresponding water outlet structure (shower, faucet, top spray) in the shower system. There is no need to set up an additional water diversion valve outside the module. Therefore, this module has a compact structure and good integrity, and is particularly suitable for shower systems. In addition, the flow regulating valve core and the water diversion valve core are both motor-controlled, thus providing a basis for the automatic control of the shower system.

[0059] like Figure 8 Shown is the second embodiment of the utility model.

[0060] The difference between this embodiment and the first embodiment is that it further includes a third temperature sensor 5c, which is arranged in the cold water outflow channel 1e to detect the water temperature of the cold water. Specifically, the third temperature sensor 5c is arranged on the first plug 11a.

[0061] By combining the cold water temperature signal detected by the third temperature sensor 5c and sending the cold water temperature data together with the aforementioned two flow rates and hot water temperature data to the information control module, it can be clearer what angle range the movable valve plates of the two flow regulating valve cores need to rotate respectively, and the movable valve plates of the flow regulating valve cores will rotate in advance to an angle closer to the set temperature.
