Description
Technical Field
The invention relates to the technical field of intelligent control of tap water outlet. More particularly, the invention relates to an intelligent double-control faucet and a control method thereof.
Background
In the fields of modern intelligent home and public health facilities, induction-controlled faucets are widely concerned and applied with convenience and sanitation. Such faucets typically combine traditional mechanical operation with advanced sensing techniques in order to provide a more intelligent, humanized use experience. However, the induction control faucet widely used in the market still has some technical limitations and user experience shortcomings in design, and is characterized in the following aspects:
first, mechanical handle and inductive control linkage problem
The existing induction control faucet generally adopts a 'dual-mode' operation design, namely, a user needs to manually open a mechanical handle to enable the faucet to enter a standby state, and then the faucet can be started to discharge water through induction (such as infrared induction). This design was initially designed to introduce the convenience of induction control while maintaining conventional operating habits. However, in the actual use process, because the habit of directly controlling the water flow by using the mechanical handle for a long time is very deep, after many users finish the use, the water outlet of the faucet is usually closed by directly operating the mechanical handle instead of closing by using the sensing function. This behavior causes the sensing system inside the faucet to fail to properly register the closed condition, so that the faucet cannot properly discharge water the next time an attempt is made to pass the sensing operation. The "misoperation trap" in the design not only affects the user experience, but also limits the effective application of the induction control technology.
Second, the control box has high cost and battery endurance problem
In advanced induction control faucets that regulate water temperature and water volume, complex control box systems are typically provided. The control boxes are internally integrated with a plurality of driving motors for accurately controlling the opening degree of the valve, the power of the heating element and the like so as to realize fine adjustment of water temperature and water flow. While this design provides a high degree of personalized customization and comfort, a concomitant problem is a significant increase in hardware cost. The use of multiple drive motors not only increases manufacturing costs, but also increases the complexity of post-maintenance. In addition, since the control box needs to be operated by power, most of the induction taps use a battery as an energy supply in order to maintain simplicity and portability of the design. However, the energy consumption of multiple driving motors results in high battery consumption, and frequent battery replacement not only brings inconvenience to users, but also increases long-term use cost, especially in public places.

The water outlet pipe 3 is used for flowing out the water treated by the valve body 5 and the water body transmission structure 6. The sensor 4 is used for detecting the operation of a user and generating a signal to be sent to the controller 7. The sensor 4 is configured to detect a user operation and generate signals to be sent to the controller 7, where the signals may include a touch, proximity or movement of the user. Specifically, the sensor 4 is selected from an infrared sensor, a touch sensor or a proximity sensor, and in this embodiment, the sensor 4 is an infrared sensor and is disposed on the opposite side of the faucet body 1 to the mechanical handle 2, so as to ensure that a user can conveniently control the faucet through sensing operation.

Preferably, the valve body 5 has two water inlets 53 corresponding to two different water inlet modes (such as cold water and hot water), and the mechanical handle 2 adjusts the water inlet ratio and water inlet amount of the two water inlets 53 by driving the valve rod 52 to rotate, so as to adjust the water outlet temperature of the water outlet 51.
The water transport structure 6 comprises two independent water inlet channels 61 and two solenoid valves 62. The two water inlet channels 61 are respectively and correspondingly connected with the two water outlets 51 independently, and each water inlet channel 61 is provided with an electromagnetic valve 62 as a control element. The two water inlet channels 61 are communicated with a single water outlet channel 63, and the water outlet channel 63 is communicated with the water outlet pipe 3. Each electromagnetic valve 62 respectively regulates and controls the communication state between the water inlet channel 61 and the water outlet channel 63, thereby realizing the control of water outlet. Each water inlet channel 61 is provided with a water flow detector 64, and each water flow detector 64 detects whether water flow exists in the water inlet channel 61, and specifically, the water flow detector 64 selects a hall water flow sensor.
The controller 7 is configured to have a state memory module capable of recording and storing the opening and closing states of the two solenoid valves 62 before the sensing operation occurs and the detection result of the last water flow detector 64, wherein when the sensor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 selects and sends a control command opposite to the last sensing control command to the corresponding solenoid valve 62 according to the state information (opening/closing) of the solenoid valve 62 stored in the controller 7 and corresponding to the last effective sensing control command before the current signal is received, and the controller 7 is a core component of the intelligent double-control faucet and is responsible for receiving the signal of the sensor 4 and sending the control command. Specifically, for example, the hand of the user approaches the sensor 4, and the sensor 4 detects a trigger condition and sends a signal to the controller 7. Specifically, the state memory module is selected as the internal memory of the controller 7. When the controller 7 needs to perform a certain operation (such as water discharge), it will first trace back to the open and closed states of the two solenoid valves 62 before the sensing operation, by looking up the state record stored in the internal memory.

The battery compartment assembly 8 allows for easy removal and replacement of batteries to ensure continued operation of the intelligent dual control faucet. Because the control box 10 does not need to be provided with a large number of driving motors, only the control elements are required to be powered, the electricity consumption is low, and the batteries do not need to be replaced frequently.

The filter element is used for removing impurities, particles and the like in water so as to ensure the cleaning of water quality and the safety of water. Specifically, the filter element is selected from the group consisting of screen 112.
Control box 10 the control box 10 is a closed outer shell 101, and the water body transmission structure 6 and the controller 7 are integrated inside. In this embodiment, the casing 101 is internally integrated with the water body transmission structure 6 and the controller 7, where the two water inlet channels 61 are symmetrically spaced, and the controller 7 and the water outlet channel 63 are disposed in a space between the two water inlet channels 61. The symmetry sets up and helps guaranteeing the evenly distributed of rivers, reduces vortex and torrent, improves the play water stability.

At least three threaded nozzles 102 are hermetically penetrated on the shell 101 and are respectively and correspondingly communicated with the water inlet ends of the two water inlet channels 61 and the outlet ends of the water outlet channels 63 in a sealing way;
The quick-connection adapter comprises a plurality of quick-connection adapter connectors 103, wherein one end of each quick-connection adapter connector 103 is a threaded end 104, the other end of each quick-connection adapter connector 103 is a clamping end 105, and the threaded ends 104 are in sealing threaded connection with the threaded pipe orifice 102;
the two connecting pipes 106, one end of the two connecting pipes 106 is respectively in sealed communication with the two water outlets 51, the other end is provided with a buckling joint 107, and is respectively in sealed communication connection with the buckling ends 105 of the quick-connection adapter 103 on the two water inlet channels 61, and the water inlet end of the water outlet pipe 3 is also provided with the buckling joint 107, and is in sealed communication connection with the buckling ends 105 of the quick-connection adapter 103 on the water outlet channel 63.

In another embodiment, the controller 7 is configured with a timing module for monitoring the time when the feedback signal from the water flow detector 64 is continuously received from the time when the feedback signal is received by the controller 7, and if a set threshold value of the time is exceeded, the operation of closing the solenoid valve 62 is performed.
In the above technical solutions, in some places where water is needed frequently but water resources are wasted due to forgetting to turn off the faucet, for example, in daily activities such as dish washing, hand washing, etc., the user may forget to turn off the faucet due to other things, which results in unnecessary waste of water resources. When the time of water flow (such as water flowing out time exceeds 3 minutes) exceeds a set threshold, the tap water flow is automatically closed, so that the tap is automatically closed when not used for a long time, and the waste of water resources is avoided.
Based on the structure of the intelligent double-control faucet, the invention also provides a control method of the intelligent double-control faucet. The method comprises the following steps:
When the sensor 4 detects a preset trigger condition and sends a signal to the controller 7, the controller 7 selects and sends a control command opposite to the last valid sensing control command to the corresponding solenoid valve 62 according to the state information of the solenoid valve 62 corresponding to the last valid sensing control command stored in the controller before receiving the current signal.
In the above-described solution, the controller 7 starts to operate when the sensor 4 detects a preset triggering condition (e.g. the user's hand is close to the sensor 4) and sends a signal to the controller 7.
The controller 7 selects and issues a control command opposite to the last valid sensing control command to the corresponding solenoid valve 62 according to the state information of the solenoid valve 62 corresponding to the last valid sensing control command stored in the controller before receiving the current signal. For example, if the effective induction control command is that the electromagnetic valve I is opened and the electromagnetic valve II is closed, the induction operation will close the electromagnetic valve I and open the electromagnetic valve II.
The controller 7 simultaneously monitors the time from the issuance of the control command to the receipt of the feedback signal. If the time exceeds the set threshold (in this embodiment, the threshold is set to be in millisecond level) and no feedback signal (such as sensing water outlet operation) is received, in this embodiment, the feedback signal is a water flow signal sent by the hall water flow sensor, and when water passes through the water inlet channel I (the water inlet channel I corresponds to the electromagnetic valve I one by one, the electromagnetic valve 62 changes from closed to open), the corresponding water flow detector 64 generates a feedback signal of water flow, and the controller 7 determines that the control command is completed at this time and is a valid control command.
In the embodiment, specifically, two water inlets 53 (a water inlet I and a water inlet II) and two water outlets 51 (a water outlet I and a water outlet II) of the valve body 5 are respectively communicated with a hot water source and a cold water source, the water inlet I and the water inlet II respectively enter a water mixing cavity in the valve body 5 through a cold water channel 108 and a hot water channel 109, the water outlet I and the water outlet II are respectively communicated with a water mixing cavity in the valve body 5 (mixed hot water and cold water respectively communicated with the water outlet I and the water outlet II through a mixed water channel I110 and a mixed water channel II 111), the position I and the position II of the mechanical handle 2 respectively correspond to two swinging angles of the valve rod 52, respectively correspond to the water outlet I and the water outlet II and the water mixing cavity are communicated, and the rotating position of the mechanical handle 2 corresponds to the rotating angle of the valve rod 52 and corresponds to controlling the water quantity of the water inlet I and the water inlet II entering the water mixing cavity;
Specifically, two water inlet channels 61 (water inlet channel I and water inlet channel II) in the control box 10 are respectively and correspondingly communicated with the water outlet I and the water outlet II in a sealing manner through two independent connecting pipes I and II, the electromagnetic valve I and the electromagnetic valve II respectively control the on-off of the water inlet channel I and the water inlet channel II, and the hall water flow sensor I and the hall water flow sensor II respectively monitor water flow signals of the water inlet channel I and the water inlet channel II.
In this embodiment, through one operation (sensing or mechanical handle 2), the operation intention of the user is realized, and the detailed description of the control logic for opening or closing the tap water outlet is realized:
1. After the faucet is installed or the battery is replaced, the control box 10 is communicated with the battery, and after the power is turned on, the initial state is set to be that the electromagnetic valve I is in a closed state and the electromagnetic valve II is in an open state;
The controller 7 monitors whether the Hall water flow sensor II generates a feedback signal (whether water flows through or not), if the Hall water flow sensor II does not generate the feedback signal (at the moment, the Hall water flow sensor II does not generate the feedback signal, which means that the mechanical handle 2 is currently positioned at the position I, the water outlet I is communicated, the water outlet II is disconnected, the water inlet channel II does not flow water, and the faucet does not discharge water), the electromagnetic valve II is kept in an open state, and the initial state adjustment of the faucet is completed, specifically, the mechanical handle 2 is positioned at the position I, the electromagnetic valve I is in a closed state, the electromagnetic valve II is in an open state, and the faucet is in a water closing state;
If there is a feedback signal (at this time, the hall water flow sensor II generates a feedback signal to indicate that the mechanical handle 2 is currently located at the position II, the water inlet channel II has water flow through, and the faucet discharges water), the controller 7 controls the electromagnetic valve II to be closed, the electromagnetic valve I to be opened, and the initial state adjustment of the faucet is completed this time, specifically, the mechanical handle 2 is located at the position II, the electromagnetic valve I is in an open state, the electromagnetic valve II is in a closed state, and the faucet is in a water-off state.
The above is the control logic when the faucet is installed or restored to an original state.
2. In the normal use process, for convenience of description, the adjustment is performed based on the initial state of completion:
before the user intends to discharge water for the faucet and operates, the state recorded in the built-in memory of the controller 7 is that the electromagnetic valve I is closed, the electromagnetic valve II is opened, and the Hall water flow sensor I and the Hall water flow sensor II are all water-free flow signals:
① Mechanical handle 2 water outlet-mechanical handle 2 water shut off control:
when a user operates the mechanical handle 2 to switch the current position (the position I is switched to the position II), at the moment, the water outlet I is disconnected, the water outlet II is communicated, the electromagnetic valve II is in an open state, the Hall water flow sensor I has no water flow signal, the Hall water flow sensor II has a water flow signal and feeds back to the controller 7, and the controller 7 records the current water outlet state, so that the water outlet of the faucet is controlled by one-time operation;
After that, when the user operates the mechanical handle 2 again to switch the current position, (the position II returns to the position I), at the moment, the water outlet I is communicated, the water outlet II is disconnected, the electromagnetic valve I is in a closed state, the Hall water flow sensor I has no water flow signal, the Hall water flow sensor II has no water flow signal and feeds back to the controller 7, and the controller 7 records the current water closing state, so that the water closing of the tap is realized by one-time operation control.
② Sensor 4 water outlet-sensor 4 water shut off control:
When the user triggers the sensor 4 and sends a signal to the controller 7, at this moment, the controller 7 inquires that the last effective induction control instruction before the current induction operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends out a feedback signal for controlling the electromagnetic valve I to be opened and the electromagnetic valve II to be closed and receiving a water flow signal of the Hall water flow sensor I, at this moment, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the mechanical handle 2 is currently positioned at the position I, the Hall water flow sensor I has a water flow signal and is fed back to the controller 7, and the controller 7 records the current water outlet state, thereby realizing one-time operation control of tap water outlet.
And after that, when the user triggers the sensor 4 again, a signal is sent to the controller 7, the controller 7 inquires that the last effective induction control instruction before the current induction operation is to control the electromagnetic valve I to be opened and the electromagnetic valve II to be closed, so that the controller 7 sends out control signals for controlling the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, and no water flow signals are required to be received from the Hall water flow sensor I and the Hall water flow sensor II, at the moment, the electromagnetic valve I is closed and the electromagnetic valve II is opened, no water flow signals are generated from the Hall water flow sensor I and the Hall water flow sensor II, and the signals are fed back to the controller 7, and the controller 7 records the current water closing state, so that the water closing of the tap is realized by one operation control.
③ Sensor 4 water outlet-mechanical handle 2 water closing control:
When the user triggers the sensor 4 and sends a signal to the controller 7, at this moment, the controller 7 inquires that the last effective induction control instruction before the current induction operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends out a feedback signal for controlling the electromagnetic valve I to be opened and the electromagnetic valve II to be closed and receiving a water flow signal of the Hall water flow sensor I, at this moment, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the mechanical handle 2 is currently positioned at the position I, the Hall water flow sensor I has a water flow signal and is fed back to the controller 7, and the controller 7 records the current water outlet state, thereby realizing one-time operation control of tap water outlet.
And thereafter, the user operates the mechanical handle 2 to switch the current position (the position I is switched to the position II), at the moment, the water outlet I is disconnected, the water outlet II is communicated, the electromagnetic valve I is opened, the electromagnetic valve II is closed, the Hall water flow sensor I and the Hall water flow sensor II have no water flow signals, the signals are fed back to the controller 7, and the controller 7 records the current water closing state, so that the water closing of the tap is realized by one-time operation control.
④ The water outlet of the mechanical handle 2 is controlled by the water outlet-sensor 4:
when a user operates the mechanical handle 2 to switch the current position (the position I is switched to the position II), at the moment, the water outlet I is disconnected, the water outlet II is communicated, the electromagnetic valve II is in an open state, the Hall water flow sensor I has no water flow signal, the Hall water flow sensor II has a water flow signal and feeds back to the controller 7, and the controller 7 records the current water outlet state, so that the water outlet of the faucet is controlled by one-time operation;
And after that, when the user triggers the sensor 4, a signal is sent to the controller 7, the controller 7 inquires that the last effective induction control instruction before the current induction operation is to control the electromagnetic valve I to be closed and the electromagnetic valve II to be opened, therefore, the controller 7 sends out a feedback signal for controlling the electromagnetic valve I to be opened and the electromagnetic valve II to be closed and receiving no water flow signals of the Hall water flow sensor I and the Hall water flow sensor II, at the moment, the electromagnetic valve I is opened and the electromagnetic valve II is closed, the Hall water flow sensor I and the Hall water flow sensor II have no water flow signals and feed back to the controller 7, and the controller 7 records the current water closing state, so that the water closing of the tap is realized by one-time operation control.
The above is the control logic during normal use of the faucet. The second initial state is the same as the first initial state control logic, and is only numbered in reverse, and will not be described again here.
3. When the operation is in error, for convenience of description, the adjustment is performed based on the initial state of completion:
⑤ When the hall water flow sensor I and the hall water flow sensor II have water flow signal feedback after the induction operation, it indicates that the mechanical handle 2 is located between the position I and the position II, and the electromagnetic valves I and II are both in an open state, and the controller 7 selects one of the electromagnetic valves 62 to be closed (in this embodiment, selects to close the electromagnetic valve I);
⑥ When it is continuously detected that there is a water flow signal feedback from the hall water flow sensor I and/or the hall water flow sensor II, and the time exceeds a set threshold (in this embodiment, the set threshold time is 3 min), the controller 7 controls the solenoid valve 62 corresponding to the hall water flow sensor to be closed.
Through the embodiment, the faucet with the intelligent double control function can be conveniently operated (the induction or mechanical handle 2) at one time, the operation intention of a user is realized, the water outlet of the faucet is opened or closed, the functions of fault detection and automatic recovery are realized, and the reliability and the user experience of the faucet are improved.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the invention would be readily apparent to those skilled in the art, and accordingly, the invention is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
