The application scenario diagram of detergent embarking device disclosed by the invention is as shown in figure 5, device disclosed by the invention
The first-class water supply installation of the fire hose is connected by water inlet, the water inlet of washing machine is connected by delivery port, detergent delivers dress automatically
Detection of swiping the card connects the coin put/payment circuit of swiping the card connection coin/card reader, the coin for paying control circuit connection washing machine/
Mouth, power supply interface connect the power line of washing machine.
Based on the device shown in Fig. 1, the invention also discloses a kind of detergent automatic delivery method, its flow chart can be as
Shown in Fig. 6, this method includes following several steps：
Step one, when washing machine is not used in user, the payment function of the device is opened, and MCU can constantly detect whether to connect
Receive the pulse signal for payment.
Step 2, if MCU does not detect the pulse signal for payment, MCU is persistently detected, until MCU inspections
Survey and received by network payment circuit and/or coin/payment interface of swiping the card the payment signal of impulse form, then it represents that user
Need to use washing machine and user is paid, now MCU opens washing machine by power supply interface and supplied for washing machine
Electricity, wherein, the payment signal that MCU is received includes payment.
Step 3, is touched because the existing washing machine based on coin/card-scanning type is only capable of receiving and handles coin/swiping card mode
The payment signal of hair, and the payment signal that the MCU in the present invention is received is in addition to the payment signal for form of inserting coins/swipe the card,
Also include the payment signal transmitted by network mode, this signal directly can not be recognized and handled by washing machine, therefore MCU is simulated
The signal inserted coins/swiped the card, is converted to virtual coin-in signal, the virtual coin according to the communication protocol pre-established by signal is paid
Signal is the payment signal for coin/form of swiping the card that washing machine can be received and handled, you can so that being transmitted by network mode
Payment signal can also control washing machine.
Step 4, MCU controls circuit that virtual coin-in signal is sent into washing machine by paying, and the virtual coin-in signal is
The signal of impulse form, the umber of pulse that washing machine is included by the virtual coin-in signal can determine payment, golden when paying
When volume reaches the amount of money needed for each washing pre-set, expression is paid successfully, can be started normal operation, be worked as payment
During the amount of money needed for each washing not up to pre-set, represent that payment is not enough, washing machine waits user to continue to pay.
Meanwhile, washing machine can control circuit that feedback signal is sent into MCU by paying, then MCU receives the feedback letter that washing machine is returned
Number, feedback signal when payment function is opened be used for indicate pay complete, forbid continue pay or for indicate insufficient in amount,
Allow to continue to pay, the feedback signal is typically the form of low and high level, is used when feedback signal is high level in the present invention
In indicating insufficient in amount, allowing to continue to pay, it is used to indicate to pay when feedback signal is low level complete, forbid continuing branch
Pay, then MCU after feedback signal is received, by detect feedback signal level judge feedback signal for indicate implication.
Step 5, when being completed when feedback signal indicates to pay, forbidding continuing to pay, the detergent embarking device is closed
Payment function, MCU no longer receives signal by payment circuit, or does not reprocess the signal received by payment circuit, together
When the detergent embarking device and washing machine all enter laundry working condition.When feedback signal indicates insufficient in amount, permission
When continuing to pay but not continuing to pay signal by payment circuit, MCU closes washing machine by power supply interface
Power supply, stops powering for washing machine.
Step 6, detergent embarking device is after laundry working condition is entered, and MCU is detected by flow sensing circuit
Water velocity, when water velocity is more than 0, then it represents that entering in the water intaking valve and washing machine in detergent embarking device
Water valve has already turned on, and the detergent embarking device is washing machine normal water supply, current washing machine by delivery port
It is in into water state.When MCU detects inflow by flow sensing circuit reaches water-carrying capacity threshold value, detergent is closed automatic
Water intaking valve in delivery device, and detergent dispensing pump is opened, detergent, which delivers pump, to be used to throw in the detergent in detergent box
Put into washing machine, wherein, water-carrying capacity threshold value is systemic presupposition value or User Defined value, can be with by adjusting water-carrying capacity threshold value
Change the opportunity of automatic detergent adding, it is necessary to which explanation, MCU can also control automatic throwing by controlling the duration of water inlet
Put the opportunity of detergent, the present invention is not limited this.
When detergent, which delivers duration of the pump in open mode, reaches preset duration, close detergent and deliver pump, and
Flow detection function is closed, namely inflow is no longer detected by flow sensing circuit, is thrown automatically while reopening detergent
The water intaking valve in device is put, preset duration is systemic presupposition value or User Defined value, can be changed by adjusting preset duration
The injected volume of each putting detergent.
Step 7, washing machine can be spaced by paying control circuit by feedback signal at predetermined time intervals in the process of running
MCU is sent to, so as to point out the working condition of itself to MCU, now the payment function of detergent embarking device, which is in, closes
Closed state, feedback signal is used to indicate that washing machine is currently running or end of run when payment function is closed, predetermined time interval
For systemic presupposition value or User Defined value, the same feedback signal is low and high level signal, when feedback signal is low level
When it is used to indicate that washing machine is currently running, feedback signal be high level when be used for indicate end of run.
When MCU receives the feedback signal for indicating washing machine end of run, MCU is closed by power supply interface
The power supply of washing machine, while MCU reopens payment function.
Above-described is only the preferred embodiment of the present invention, and the invention is not restricted to above example.It is appreciated that this
Other improvement and become that art personnel directly export or associated without departing from the spirit and concept in the present invention
Change, be considered as being included within protection scope of the present invention.
