Description

Technical Field

[0001] This invention relates to an intelligent three-way valve for use in the field of heating, ventilation, and air conditioning (HVAC), and more specifically, to a temperature-controlled electric three-way valve and its regulating system. Background Technology

[0002] Thermostatic three-way valves are mainly used in domestic hot water systems. With the continuous improvement of people's living standards and the increasing awareness of energy conservation and environmental protection, the application of domestic hot water systems is becoming more and more widespread. However, traditional domestic hot water systems often cannot effectively regulate and control the hot water temperature, leading to problems such as energy waste and inconvenience. Against this backdrop, thermostatic three-way valves have emerged. They can monitor the water temperature and flow rate in the hot water pipes in real time and achieve a constant water temperature by adjusting the ratio of hot and cold water supply. Therefore, using thermostatic three-way valves can effectively save energy consumption, reduce operating costs, and ensure users receive a comfortable and stable hot water supply experience.

[0003] Traditional thermostatic three-way valves typically adjust the opening of the hot and cold water inlets based on the outlet water temperature. Furthermore, the water flow rate of a traditional thermostatic three-way valve is not related to the outlet water temperature. This approach usually has the following drawbacks: When the water flow rate at a particular inlet of the three-way valve fluctuates, the temperature sensor cannot detect the anomaly. Checking the outlet temperature will lead to inconsistent water temperatures at the overall outlet. The water flow rate at the outlet of the three-way valve is uncontrollable, and it cannot automatically close the outlet when abnormal water temperature occurs, potentially causing damage to downstream equipment and users.

[0004] To address the two aforementioned shortcomings, a technical solution is provided. Summary of the Invention

The equipment control module controls the separator and motor through the variable speed motor drive parameters, separator control parameters, and water distribution plate motor drive parameters.

[0012] In a preferred embodiment, the temperature-controlled electric three-way valve and regulating system are characterized in that the controller includes the following control steps; S1: The data acquisition module collects the water temperature in the cold water pipe, the water temperature in the hot water outlet pipe, the water temperature in the outlet pipe, the water flow velocity in the cold water pipe, the water flow velocity in the hot water pipe, the direction and speed of the planetary carrier shaft in real time, and uploads the data to the processing module.

S2.1: When the equipment is started and the separator is in the off state, the direction and speed of the planetary carrier shaft rotation are determined. Generate variable speed motor drive parameters : ; In the formula The sign indicates the direction of rotation of the planetary carrier axis. The absolute value is the rotational speed; S2.2: When the equipment is in operation, the flow rate is determined based on the readings from the cold water pipe flow rate sensor. hot water pipe flow rate sensor reading Cold water pipe temperature sensor reading hot water pipe temperature sensor reading Preset water temperature information Generate separator control parameters : ; S2.3: When it is necessary to use a motor to control the outlet water temperature, the reading from the outlet temperature sensor shall be used.

When the speed change motor drive parameters are greater than 0, the movable bracket moves away from the fixed bracket through the speed change motor.

When both the parameters of the water distribution plate drive motor and the variable speed motor drive parameters are equal to 0, the brake device is locked, the separator is closed, and the regulating mechanism is used again to control the outlet water temperature.

When the water pressure at the inlet pipe decreases, causing changes in water flow, this equipment can maintain the water temperature at the outlet using only the mechanical structure. Moreover, the mechanical structure adjusts the water temperature promptly and effectively, without affecting the water temperature at the outlet.

When there is no water supply due to an abnormality at the hot water inlet or cold water inlet, the regulating mechanism (50) will control the water distribution plate to automatically block the inlet without abnormality, so that the user will not be affected by water temperature issues when using the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1

[0020] like Figures 1-8As shown, a temperature-controlled electric three-way valve and its regulating system include a three-way valve body and a controller 701. The controller 701 is fixed on the surface of the three-way valve body. A cold water inlet pipe 10 and a hot water inlet pipe 20 are provided on one side of the three-way valve body. Water flow sensors are provided on the cold water inlet pipe and the hot water inlet pipe. An outlet pipe 601 is provided on the other side of the three-way valve body. The three-way valve body is characterized by having a mixing mechanism connected to the cold water inlet pipe, the hot water inlet pipe, and the outlet pipe. A water distribution plate 609 is provided inside the mixing mechanism 60. The water distribution plate 609 is used to control the mixing ratio of cold and hot water. A water flow sensor shaft is provided on the water flow sensor. An regulating mechanism 50 is connected to the water flow sensor shaft. The regulating mechanism 50 controls the opening and closing angle of the water distribution plate 609 by the difference in the rotation speed of the flow sensor shaft.

[0021] The bottom of the device is equipped with a cold water inlet pipe 10 and a hot water inlet pipe 20. Water flow sensors and temperature sensors are installed on the cold water inlet pipe 10 and the hot water inlet pipe 20. A mixing mechanism 60 is installed at the end of the cold water inlet pipe 10 and the hot water inlet pipe 20. The device drives the water distribution plate 609 to rotate through the water distribution plate rotating shaft 606 inside the mixing mechanism 60. The water distribution plate 609 can set the opening ratio of the cold and hot water pipes according to preset information, thereby affecting the temperature of the cold and hot water after mixing. A water tank plate 610 is installed at the rear end of the water distribution plate 609. The water tank plate 610 has openings. A baffle plate 611 is installed at the top of the water tank plate 610. The baffle plate 611 can block the openings on the water tank plate 610 under the action of the baffle plate rotating shaft 612. A water outlet pipe 601 is installed at the rear end of the baffle plate 611.

[0022] The adjusting mechanism 50 contains a small gear 508, with a first rotating shaft 503 connected to its center. A short-belt driven pulley 502 is connected to the other end of the first rotating shaft 503. A steering gear 515 is mounted on the first rotating shaft 503. Planetary gears mesh around the small gear 508, with the outer gear ring 509 of the planetary gears meshing with the small gear 508. A planet carrier 501 is fixed to the center of each planetary gear 504. A long-belt driven pulley 510 is connected to one end of the sun gear 510 of the planetary gears. 11. A planetary carrier shaft 505 is provided on the planetary carrier 501. One end of the planetary carrier shaft 505 is connected to a separator 506. The other end of the separator 506 is provided with a second shaft 514. The separator 506 can disconnect the planetary carrier shaft 505 and the second shaft 514. The end of the second shaft 514 is connected to a linkage gear 507 box. A coupling 512 is provided on the linkage gear 507 box. A speed sensor 513 for detecting the rotational speed of the planetary carrier shaft 505 is provided inside the adjustment mechanism 50.

[0023] One end of the water distribution plate shaft 606 in the mixing mechanism 60 is connected to the water distribution plate 609, and the other end is connected to the water distribution plate drive motor 602 in the adjusting mechanism 50 and the transmission shaft through a gear mechanism. The other end of the transmission shaft is connected to the separator 506, which can transmit the rotation of the planetary carrier shaft 505 to the transmission shaft. The other end of the planetary carrier 501 is connected to the planetary gear 504. The external gear ring 509 of the planetary gear containing the planetary gear 504 meshes with the pinion 508. The sun gear 510 of the planetary gear is connected to the long belt driven pulley 511. The pinion 508 is connected to the short belt driven pulley 502 of the steering gear 515 via the first rotating shaft 503. When the speeds of the short belt driven pulley 502 and the long belt driven pulley 511 are inconsistent, the planetary gear 504 will drive the planetary carrier 501 to rotate. At this time, the speed sensor 513 in the adjustment mechanism 50 will detect the rotation of the planetary carrier shaft 505. If the separator 506 is engaged at this time, the planetary carrier 501 will directly drive the water distribution plate 609 to rotate. The function of the steering gear 515 is to make the rotation directions of the two shafts inconsistent through the internal structure.

[0024] The transmission mechanism 30 is disposed between the water flow sensor and the regulating mechanism 50. A long belt drive pulley 304 is fixed on the rotating shaft of the hot water pipe flow velocity sensor 203. A long belt 302 is disposed on the long belt drive pulley 304, and the other end of the long belt 302 is connected to a long belt driven pulley 511. A speed change mechanism 40 is disposed on the rotating shaft of the cold water pipe flow velocity sensor 103. The drive shaft 403 in the speed change mechanism 40 is connected to the rotating shaft of the cold water pipe flow velocity sensor 103. A drive fixed pulley 405 and a drive movable pulley 404 are disposed on the drive shaft 403. A steel belt 414 is disposed between the drive fixed pulley 405 and the drive movable pulley 404, and the other end of the steel belt 414 is connected to the driven shaft 411. The driven shaft 411 is provided with a driven fixed pulley 412 and a driven movable pulley 413. The transmission mechanism 40 is provided with a fixed bracket 408 and a movable bracket 410. The driving shaft 403 and the driven shaft 411 are provided on the fixed bracket 408. The driving fixed pulley 405 and the driven fixed pulley 412 are fixed on the fixed bracket 408 through the driving shaft 403 and the driven shaft 411. The driving movable pulley 404 and the driven movable pulley 413 are connected to the movable bracket 410 through the movable shaft. The end of the driven shaft 411 is connected to a short belt 301 driving pulley. The short belt driving pulley 303 is provided with a short belt 301. The other end of the short belt 301 is provided with a short belt driven pulley 502.

[0025] The transmission mechanism 30 includes a long belt 302, a short belt 301, and a speed change mechanism 40. The long belt 302 is connected to a long belt driven pulley 511 at both ends and a long belt 302 driving pulley on the hot water pipe flow velocity sensor. The short belt 301 is connected to a short belt driven pulley 502 at both ends and a short belt driving pulley 303 on the speed change mechanism 40. The speed change mechanism 40 is located between the cold water pipe flow velocity sensor 103 and the adjustment mechanism 50.

[0026] The power transmitted by the speed change mechanism 40 comes from the rotating shaft of the cold water pipe flow rate sensor 103. The motor 401 of the speed change mechanism 40 drives the driven gear 407 to rotate through the gear shaft 406. The rotation of the driven gear 407 can drive the driven rack to move laterally. The movement of the driven rack will drive the driven frame to move. The movement of the driven frame will drive the driving pulley 404 and the driven pulley 413 to move horizontally. When the driving pulley rotates under the drive of the flow rate sensor shaft, the driving pulley will drive the steel belt 414 to rotate. The steel belt 414 will drive the driven pulley to rotate. The driven pulley will drive the short belt driving pulley 303 to rotate. If the speed change mechanism motor 401 starts working at this time, it will change the rotation ratio between the driving pulley and the driven pulley. When the transmission ratio reaches the expected effect, the brake device 402 can be used to prevent the driven frame from moving.

[0027] The mixing mechanism 60 has a base box 605 at its bottom, on which a cold water inlet 607 and a hot water inlet 608 are provided. A water distribution plate shaft 606 is installed on the base box 605. One end of the water distribution plate shaft 606 is connected to a water distribution plate drive motor 602, and the other end is connected to a water distribution plate 609. The water distribution plate 609 can block the cold water inlet 607 and the hot water inlet 608 under the drive of the water distribution plate drive motor 602. A water tank plate 610 is provided on the top of the water distribution plate 609. The body of the water tank plate 610 is provided with a water tank plate opening 614. A water baffle plate 611 is provided on the top of the water tank plate 610. A water baffle plate shaft 612 is provided on the water baffle plate 611, and the other end of the water baffle plate shaft 612 is connected to a water baffle plate drive motor 603.

[0028] The main function of the mixing mechanism 60 is to mix the cold water and hot water entering the equipment in a certain proportion. The mixing ratio of cold and hot water is achieved through the water distribution plate 609, as shown in the reference. Figure 6 As shown, the water distribution plate 609 is fixed on the water distribution plate rotating shaft 606 and can be driven by the water distribution plate drive motor 602 and the adjustment mechanism 50. The water distribution plate 609 can control the opening ratio of the cold water inlet 607 and the hot water inlet 608, thereby controlling the water temperature. The liquid passing through the water distribution plate 609 will flow onto the water tank plate 610. The water tank plate 610 has openings, and a baffle plate 611 is provided on the top of the water tank plate 610. The function of the baffle plate 611 is to block the openings on the water tank plate 610, thereby realizing the opening and closing of the valve.

[0029] A cold water inlet pipe 10 is equipped with a cold water pipe temperature sensor 102, a hot water inlet pipe 20 is equipped with a hot water pipe temperature sensor 202, and an outlet pipe 601 is equipped with an outlet pipe temperature sensor 604.

[0030] By installing corresponding water temperature sensors on the cold water inlet pipe 10, hot water inlet pipe 20, and outlet pipe 601, the water temperature can be monitored in real time, providing a reference and standard for water temperature control, ensuring that users obtain the required comfortable water temperature, and improving the water use experience.

[0031] The above describes how the various parts of the mechanical structure work in coordination; the following describes how the systems cooperate with each other.

[0032] When the equipment starts, the transmission ratio of the control speed change mechanism 40 is: At this point, disconnect separator 506 and use water distribution plate drive motor 602 to drive water distribution plate 609 to rotate. The customer can then set the outlet water temperature. When the customer is satisfied with the outlet water temperature, the desired water temperature can be obtained. If the speed sensor 513 detects that the planetary carrier shaft 505 is rotating, it means that the ratio of the water flow velocity in the hot and cold water pipes is inconsistent with the transmission ratio of the speed change mechanism 40. At this time, it is necessary to adjust the position of the driven frame by adjusting the motor 401 of the speed change mechanism 40. As the driven frame moves, the transmission ratio of the speed change mechanism 40 decreases. When the transmission ratio of the speed change mechanism 40 is equal to the ratio of the water flow velocity in the hot and cold water pipes, the speed sensor 513 can detect that the planetary carrier shaft is no longer rotating. Then, the brake device 402 brakes and engages the separator 506. In this way, the equipment completes the initialization.

[0033] After initialization is complete, the equipment starts working. If the hot water flow rate decreases, the rotation speed of the water flow sensor shaft on the hot water pipe will decrease. As a result, the rotation speeds of the sun gear 510 and the pinion 508 will be inconsistent, causing the planetary carrier 501 to begin to deflect. The planetary carrier 501 then drives the separator 506 to rotate. The separator 506, through its rotating shaft, drives the water distribution plate shaft 606 to rotate towards the inlet with a flow rate higher than expected. The water distribution plate 609 will then further block the inlet with a flow rate higher than expected and further open the inlet with a flow rate lower than expected, keeping the ratio of water flow velocity entering the three-way valve consistent, thereby ensuring the water temperature.

[0034] After initialization is complete, the equipment starts working. If the hot water temperature drops, the separator 506 is disconnected. The rotation angle of the water distribution plate 609 is controlled according to the outlet water temperature. The outlet water temperature is controlled by the water distribution plate drive motor 602 to ensure the minimum functional limit.

[0035] Example 2

[0036] The controller 701 includes the following control modules; The data acquisition module collects the water temperature inside the cold water pipe, the water temperature inside the hot water outlet pipe, the water temperature inside the outlet pipe 601, the water flow velocity inside the cold water pipe, the water flow velocity inside the hot water pipe, the direction and speed of rotation of the planetary carrier shaft 505, and the preset water temperature information, and sends the data to the processing module. The processing module processes the data uploaded by the data acquisition module to generate variable speed motor drive parameters, separator 506 control parameters and water distribution plate 609 motor drive parameters, and sends the generated results to the equipment control module. The equipment control module controls the separator 506 and the motor through the variable speed motor drive parameters, the separator 506 control parameters, and the water distribution plate 609 motor drive parameters.

[0037] The advantage of this design lies in its ability to precisely monitor and control water temperature and flow rate, as well as to monitor the rotation direction and speed of the planetary carrier shaft 505 in real time. Data acquired by the data acquisition module is processed by the data processing module to generate corresponding drive and control parameters, thereby achieving precise control of the separator 506 and the motor. This design improves system stability and efficiency, ensuring that water temperature and flow rate remain within preset ranges, and enabling intelligent management and optimized operation of the equipment. Simultaneously, monitoring the rotation direction and speed of the planetary carrier shaft 505 allows for timely detection of abnormalities and the implementation of corresponding measures to ensure the normal operation of the system. In summary, this design enhances the system's reliability, flexibility, and intelligence, providing users with a more comfortable and efficient user experience.

[0038] The controller 701 includes the following control steps; S1: The data acquisition module collects the water temperature inside the cold water pipe, the water temperature inside the hot water outlet pipe, the water temperature inside the outlet pipe 601, the water flow velocity inside the cold water pipe, the water flow velocity inside the hot water pipe, the direction and speed of rotation of the planetary carrier shaft 505 in real time, and uploads the data to the processing module. S2: The processing module processes the information uploaded by the acquisition module and performs data processing. S2.1: When the equipment is started and the separator 506 is in the off state, the direction and speed of rotation of the planetary carrier shaft 505 are determined according to... Generate variable speed motor drive parameters The specific calculation expression can be: In the formula The positive and negative signs indicate the direction of rotation of planetary carrier shaft 505. The absolute value is the rotational speed; taking the planetary carrier shaft 505 as viewed from the direction of the planetary carrier 501, the clockwise rotation of the planetary carrier shaft 505 is the positive direction. When the planetary carrier shaft 505 rotates clockwise, it means that the rotational speed of the short belt driven wheel 502 is greater than that of the long belt driven wheel 511. When setting the preset water temperature information, the rotational speed of the short belt driven wheel 502 can be reduced by adjusting the transmission ratio of the speed change mechanism 40, so that the planetary carrier shaft 505 stops rotating, and the speed change mechanism 40 in the transmission mechanism (30) is initialized.

[0039] S2.2: When the equipment is in operation, the readings from the cold water pipe flow rate sensor 103 are used to determine the flow rate. hot water pipe flow rate sensor 203 reading Cold water pipe temperature sensor 102 reading hot water pipe temperature sensor 202 reading Preset water temperature information Generate control parameters for separator 506 The specific calculation expression can be: The latter part of the formula calculates the outlet water temperature. The outlet water temperature is inferred by collecting information from the equipment inlet. This can anticipate water temperature fluctuations and improve regulation efficiency. The specific prediction process is to add the product of cold water temperature and cold water inlet volume to the product of hot water temperature and hot water inlet volume, and divide by the total inlet volume. When it is predicted that the water entering the equipment cannot meet the expected temperature through the current mixing ratio, the separator 506 is disconnected and the water distribution plate drive motor 602 is used to control the water distribution plate 609 to adjust the current cold and hot water mixing ratio.

[0040] S2.3: When it is necessary to use a motor to control the outlet water temperature, the reading from the outlet temperature sensor shall be used. Preset water temperature information Generate the motor drive parameters for the water distribution plate 609. The specific calculation expression can be: This involves comparing the water temperature inside the 601 outlet pipe with the preset water temperature to ensure that the outlet water temperature remains consistent even when the inlet water temperature is lower than expected. S3: The equipment control module controls the operation of the equipment based on the control parameters generated by the processing module; S3.1: When the equipment starts, the separation device is disconnected, and the speed change mechanism 40 is initialized by the speed change motor drive parameters. When the speed change motor drive parameters are greater than 0, the movable support 410 is moved away from the fixed support 408 by the speed change motor. When the speed change motor drive parameters are less than 0, the movable support 410 is moved closer to the fixed support 408 by the speed change motor. When the speed change motor drive parameters are equal to 0, the brake device 402 is locked, the separator 506 is closed, and the initialization ends. When the speed change motor drive parameters cannot be equal to 0, the distance between the movable support 410 and the fixed support 408 is adjusted to minimize the absolute value of the speed change drive motor, and the brake device 402 is locked. S3.2: Set a threshold range for the control parameters of separator 506. This range is the error range of mechanical temperature regulation. When the control parameters of separator 506 are within the threshold range, separator 506 is closed to use mechanical temperature regulation. When the control parameters of separator 506 exceed the threshold, separator 506 is opened and the water distribution plate drives motor 602 to control the outlet water temperature. S3.3: If the separator 506 is disconnected during equipment operation, the water distribution plate drive motor 602 is used to control the outlet water temperature. When the motor drive parameter of the water distribution plate 609 is greater than 0, the water distribution plate 609 rotates towards the cold water inlet 607. When the motor drive parameter of the water distribution plate 609 is less than 0, the water distribution plate 609 rotates towards the hot water inlet 608.

[0041] S3.4: Set a time threshold. When the parameters of the water distribution plate drive motor 602 are equal to 0, and the parameters of the water distribution plate drive motor 602 do not change within a certain period of time, the brake device 402 is released, and the movable bracket 410 is controlled to move according to the new drive parameters of the variable speed motor 401. When both the parameters of the water distribution plate drive motor 602 and the drive parameters of the variable speed motor 401 are equal to 0, the brake device 402 is locked, the separator 506 is closed, and the regulating mechanism 50 is used again to control the outlet water temperature.

[0042] The control system is configured in this way for the following advantages: The data acquisition module collects the water temperature and flow rate of the cold water pipe, hot water outlet pipe, and outlet pipe 601 in real time, and sends the data to the processing module for processing. The processing module generates drive parameters for the variable speed motor, control parameters for the separator 506, and drive parameters for the water distribution plate 609 motor based on the collected data, and controls the operation of the separator 506 and the motor through the equipment control module. This allows for precise adjustment of water temperature and flow, meeting users' needs for different temperatures and flow rates. The data acquisition module in the controller 701 monitors the readings of each sensor in real time and transmits the data to the processing module for processing. The processing module generates corresponding control parameters based on preset water temperature information and other parameters, and sends the results to the equipment control module. The equipment control module controls the operation of the separator 506 and the motor based on the received control parameters, thereby achieving intelligent temperature and flow control. By precisely controlling the water flow rate and clutch state, energy can be effectively utilized and saved. When it is necessary to adjust the water temperature or flow rate, the controller 701 can intelligently adjust according to actual needs, avoiding unnecessary energy waste and reducing energy costs. The controller 701 is designed to allow users to adjust the water temperature and flow according to their needs. By setting a threshold range, when mechanical temperature control cannot meet the requirements, the separator 506 is disconnected, and the water distribution plate drives the motor 602 to control the outlet water temperature.
