The device operation indicator light is installed at the upper left corner of the front of the main controller.

[0060] The main controller adopts a wireless radio frequency control mode, and the main controller is inserted into the socket installed on the wall of the toilet.

[0061] The chip model of the offline voice module 104 is JX108. The offline voice module 104 adopts DSP for efficient processing of voice signals, including voice collection, noise reduction, feature extraction, supports 3-5 meter far field voice recognition, and the command recognition rate is 98%.

Figure 6

[0065] The local socket 107 adopts a direct-current control alternating-current solid-state relay 106, and the on-off of the local socket 107 is controlled through a voice instruction. The output parameter is voltage AC220V and current 10A;

[0067] The on-off of the local socket 107 on the front of the main controller is local voice control. When the voice command “turn on the socket”, the B7 (as shown in the offline voice module pin diagram) of the I / O end of the offline voice module 104 generates a high-level signal to trigger the signal end of the solid-state relay 106, the internal light-emitting diode is turned on and the silicon-controlled silicon is turned on.

Figure 15 The main controller is provided with a 5V / 3000mAh lithium battery group A102B, which provides working power supply for the offline voice module 104 and the radio frequency transmitting module 105, and the main controller can still control the flushing of the closestool and the water faucet by voice command in case of power failure. The controller has a continuous operation time of ≥60 days after the lithium battery group is fully charged once.

[0069] The power module 102A is connected with the lithium battery group A102B and the solid state relay 106 respectively, and is used for providing working power supply for the system and charging of the lithium battery group A102B (see the control circuit diagram of the local socket in the description Figure 1 ).

[0070] The pin 7 of the offline voice module 104 is connected with the pin D7 of the radio frequency transmitting module 105; the pin 21 of the offline voice module 104 is connected with the pin D6 of the radio frequency transmitting module 105; the pin 22 of the offline voice module 104 is connected with the pin D5 of the radio frequency transmitting module 105; the pin 5 of the offline voice module 104 is connected with the pin D4 of the radio frequency transmitting module 105; the pin 4 of the offline voice module 104 is connected with the pin D3 of the radio frequency transmitting module 105; the pin 3 of the offline voice module 104 is connected with the pin D2 of the radio frequency transmitting module 105; the pin 1 of the offline voice module 104 is connected with the pin D1 of the radio frequency transmitting module 105; and the pin 2 of the offline voice module 104 is connected with the pin D0 of the radio frequency transmitting module 105 (see the control circuit diagram of the local socket in the description Figure 4 and 6 ).

[0071] When the user gives a voice command, the corresponding I / O end of the offline voice module 104 generates a high level signal to trigger the radio frequency transmitting module 105, and sends a wireless radio frequency signal to space. When the radio frequency receiving module on the closestool flushing controller, the water faucet cold and hot water outlet controller or the bathing hot air blower controller receives the wireless radio frequency signal, the closestool flushing controller, the water faucet cold and hot water outlet controller or the bathing hot air blower controller are actuated through decoding.

[0072] The radio frequency receiving module (receiving frequency is 433.92MHz) receives the coded signal from the transmitting module 105, and after decoding, drives the flush pressing motor 113, the hot water electromagnetic valve 117A, the cold water electromagnetic valve 117B, the first solid-state relay 119A, the second solid-state relay 119B, the single fire switch module A 121A and the single fire switch module B 121B to act, realizing independent addressing and control of multi-path load switch.

[0073] The toilet flush controller comprises a lithium battery pack B110, a first radio frequency receiving module 111, a motor forward and reverse module 112 and a flush pressing motor 113 (see the attached Figure 7 The flush pressing motor 113 is installed on the upper end of the toilet drain valve by a clamp.

[0074] The lithium battery pack B110 is 5V / 3000mAh, is a 18650 battery core, the charging current is 2A, the charging port adopts a type-c port, and has an electric quantity display; the lithium battery pack B110 is fully charged once, and the controller has a continuous use time of ≥90 days.

[0075] The lithium battery pack B110 is connected with the first radio frequency receiving module 111, the motor forward and reverse module 112 and the flush pressing motor 113 respectively; the first radio frequency receiving module 111 is connected with the motor forward and reverse module 112; and the motor forward and reverse module 112 is connected with the flush pressing motor 113.

[0076] The first radio frequency receiving module 111 receives the voice instruction from the main controller, converts it into a 2000 pulse period high level through decoding, drives the motor forward and reverse module 112 to make the motor push rod rotate forward to press the flush downward for the first 1000 pulses, and make the motor reverse to reset for the last 1000 pulses, to complete the toilet flush (see the attached Figure 8 ).

[0077] The lithium battery pack B110 provides uninterrupted power supply for the toilet flush controller, and the toilet can also be flushed through the voice instruction when power is off; the toilet flush controller is a rectangular plastic box, which is pasted on the wall behind the toilet tank, and the flush motor is placed in the toilet tank.

[0078] The faucet cold and hot water outlet controller comprises a lithium battery pack C114A, a second radio frequency receiving module 115, a DC voltage reduction module 114B, a first switch module 116A, a second switch module 116B, a hot water electromagnetic valve 117A and a cold water electromagnetic valve 117B; the hot water electromagnetic valve 117A is connected with a hot water angle valve through a soft water pipe; and the cold water electromagnetic valve 117B is connected with a cold water angle valve through a soft water pipe.

[0079] Lithium battery C114A is 12V / 4000mAh, 18650 battery; the charging current is ≤4A, and the charging port adopts type-c port with power display.

[0080] Lithium battery C114A is connected with first switch module 116A, second switch module 116B, hot water electromagnetic valve 117A and cold water electromagnetic valve 117B respectively; lithium battery C114A is connected with DC voltage reduction module 114B; DC voltage reduction module 114B is connected with second radio frequency receiving module 115; second radio frequency receiving module 115 is connected with first switch module 116A and second switch module 116B respectively; first switch module 116A is connected with hot water electromagnetic valve 117A; second switch module 116B is connected with cold water electromagnetic valve 117B, and the working voltage of hot water electromagnetic valve 117A and cold water electromagnetic valve 117B is DC 12V (see the attached Figure 9 )。

[0081] Second radio frequency receiving module 115 receives voice instructions from the main controller, converts them into high / low level through decoding, drives first switch module 116A and second switch module 116B on / off, and then controls the opening / closing of hot water electromagnetic valve 117A and cold water electromagnetic valve 117B, so as to make the faucet discharge cold water / hot water.

[0082] The faucet controlled by the faucet cold / hot water outlet controller can discharge cold water, hot water and cold / hot mixed water (see the attached Figure 8 Faucet cold / hot water outlet control circuit diagram). Specific voice instructions are: “open hot water”, “open cold water”, “open faucet (cold / hot mixed water)”. The machine replies: “the faucet is opened, and will be closed in 30 seconds” (water saving consideration, the faucet discharges water for 30 seconds once). The total reply for stopping water discharge is: “turn off the water”. The water quantity of the faucet in this application can be accurately quantified (such as a cup of water (100ml) or a basin of water (1000ml)), and can also be time quantified (such as closing after 30 seconds or closing after 3 minutes). Once the lithium battery is fully charged, the controller can work for ≥60 days.

[0083] Lithium battery C114A provides uninterrupted power supply for the controller, and can also control the cold / hot water of the faucet through voice instructions when the power is off, and provides 5V working voltage for second radio frequency receiving module 115. The controller is a rectangular plastic box placed in the bathroom cabinet.

[0084] When the user issues a voice instruction, such as “open hot water”, A25 of offline voice module 104I / O end (such as Figure 4The off-line voice module pin diagram generates a high level signal to trigger the D2 of the radio frequency transmitting module 105, and sends a radio frequency signal to the space. When the second radio frequency receiving module 115 receives the signal transmitted by the radio frequency transmitting module 105, the corresponding hot water electromagnetic valve 117A controlling hot water is turned on through decoding, and the hot water pipe flows out hot water (the principles of other controlled devices are the same).

[0085] The shower hot air fan controller is a rectangular plastic box placed above the ceiling of the bathroom; the shower hot air fan controller includes a 5V power module, a third radio frequency receiving module 118, a first solid state relay 119A, and a second solid state relay 119B (see the attached Figure 11 The 5V power module converts AC 220V to DC 5V, providing working power for the third radio frequency receiving module 118.

[0086] The third radio frequency receiving module 118 is connected with the first solid state relay 119A and the second solid state relay 119B; the first solid state relay 119A is connected with the first hot air fan 120A; the second solid state relay 119B is connected with the second hot air fan 120B (see the attached Figure 11 ).

[0087] The third radio frequency receiving module 118 receives voice commands from the main controller, converts them into high / low level signals through decoding, triggers the signal end of the solid state relay, makes the internal light emitting diode conduct or cut off, and then triggers the silicon controlled rectifier to conduct or close, controlling the PTC electric hot air fan (such as Figure 12 The shower hot air fan control circuit diagram), so that the silicon controlled rectifier conducts to realize local socket load spark-on / off.

[0088] The shower hot air fan controller controls the hot air fan in two grades, according to the indoor temperature required during bathing, through voice commands, one way on or two-way full on.

[0089] The lamp controller is a single fire switch module A 121A; the single fire switch module A 121A includes a power converter, a radio frequency receiving module, and a silicon controlled rectifier drive switch (see the attached Figure 13 and 14 ).

[0090] The ventilation fan controller is a single fire switch module B 121B, which includes a power converter, a radio frequency receiving module, and a relay; the ventilation fan controller realizes intelligent switch power supply and load control through a single fire wire without zero line.

[0091] Single fire switch module A121A and single fire switch module B121B are installed in the switch box (86 type) of the light and ventilation fan wall, and are connected in parallel with the switch "K" (light wall button switch). Single fire switch module A121A and single fire switch module B121B are designed with a micro-current path inside, allowing a small current (μA to mA level) to pass through the load to form a closed loop. Using a resistance-capacitance voltage reduction or switch power supply chip, the small current is converted into a low voltage (such as 3.3V or 5V) required for module operation. When the radio frequency receiving module receives voice instructions from the main controller, it is converted into high / low level through decoding, triggering the signal end of the driving switch, making the silicon controlled rectifier or relay conductive or cut off, to control the on / off of the light (ventilation fan).

[0092] When the user says the wake-up word (such as: Hello Xiao Zhi), the voice collection microphone uses beamforming technology to direct the sound, so that the system is awakened from sleep and enters the working state (the working state can be set within 5-60 seconds).

[0093] The offline voice module 104 extracts the control keywords (such as "turn on the light" and "turn off the faucet"), and then converts the voice command into a control instruction code.

[0094] If the control instruction code corresponds to a regular load, the main controller sends a radio frequency signal containing an address code (A1) and an action code (0x01) through the radio frequency transmission module 105, and drives the solid-state relay, single fire switch module A121A and single fire switch module B121B, flush pressing motor 113, hot water electromagnetic valve 117A and cold water electromagnetic valve 117B at the target receiving end.

[0095] If the control instruction code corresponds to a high-power load (such as a shower hot air machine), the main controller starts zero-crossing detection and triggers the solid-state relay to conduct at the zero-crossing point of alternating current, while monitoring the temperature and current state.

[0096] In the above process, each load is provided with an LED indicator light (green-normal, red-fault); the command reply loudspeaker broadcasts the operation result (such as "the faucet has been opened, and will be closed in 30 seconds").

[0097] The bathroom control device with voice control function solves the problems of single function, unsafe high-power control and strong network dependence of traditional intelligent products through the technical solutions of multi-modal control integration, dynamic addressing and conflict avoidance, and solid-state relay (SSR) multiple safety protection mechanism solution, and is especially suitable for the needs of bathroom control.
