The coin of dynamic delivery device/cCredit card payment circuit connection coin/card reader, the coin/brush for paying control circuit connection washing machine
The power line of card detection interface, power supply interface connection washing machine.
The operation principle of detergent embarking device disclosed in the utility model is：
Step 1, 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 is examined
Survey and pass through network payment circuit and/or the payment signal of coin/cCredit card payment interface to 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, 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 utility model is received except form of inserting coins/swipe the card payment signal it
Outside, in addition to by network mode the payment signal transmitted, this signal directly can not be identified and handled by washing machine, therefore MCU
The signal inserted coins/swiped the card is simulated, virtual coin-in signal is converted to by signal is paid according to the communication protocol pre-established, this is virtual
Coin-in signal is the payment signal for coin/form of swiping the card that washing machine can be received and handled, you can so that passing through network mode
The payment signal of transmission can also control washing machine.
Virtual coin-in signal is sent to washing machine by step 4, MCU by paying control circuit, 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, payment deficiency is represented, washing machine waits user to continue to pay.
Meanwhile feedback signal can be sent to MCU by washing machine by paying control circuit, then MCU receives the feedback letter that washing machine returns
Number, feedback signal when payment function is opened be used for indicate pay complete, forbid continuing to pay or for indicate insufficient in amount,
Allow to continue to pay, the feedback signal is typically the form of low and high level, when feedback signal is high level in the utility model
When be used for indicate insufficient in amount, allow to continue to pay, when feedback signal be low level be used for indicate pay completion, forbid continuing
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 is no longer by payment circuit reception signal, 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, stop powering for washing machine.
Step 6, after working condition of doing washing is entered, MCU is detected detergent embarking device 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 by delivery port, at present washing machine
It is in into water state.When MCU detects that inflow reaches water-carrying capacity threshold value by flow sensing circuit, it is automatic to close detergent
Water intaking valve in delivery device, and open detergent and launch pump, detergent launches pump and is 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
The opportunity of detergent is put, the utility model is not limited this.
When the duration that detergent dispensing pump is in open mode reaches preset duration, close detergent and launch pump, and
Flow detection function is closed, namely inflow is no longer detected by flow sensing circuit, while reopens detergent and throws automatically
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 prompt the working condition of itself to MCU, now the payment function of detergent embarking device, which is in, closes
Closed state, feedback signal are 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, when feedback signal is high level 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 preferred embodiment of the present utility model, and the utility model is not limited to above example.Can
To understand, what those skilled in the art directly exported or associated on the premise of spirit of the present utility model and design is not departed from
Oher improvements and changes, it is considered as being included within the scope of protection of the utility model.
