Description
System regions
The present invention relates to refrigerator system fields, and in particular to a kind of electric flap feedback control system.
Background system
Wind cooling refrigerator in existing system all uses electric flap mostly, but the electric flap in existing system is generally not
The position feed back signal of the aperture of air door can be transmitted to CPU, not the position feedback information of electric flap.Under normal circumstances may be used
The angle of air door rotation is controlled using control pulse frequency number, but under special circumstances, for example door shaft of air door is stuck, Huo Zhefeng
Door heater operation irregularity when air door is frozen in, is possible to be distorted, controls mesh to be achieved with pulse frequency driving
Cursor position may not be actual position.Not only expensive if directlying adopt angular displacement sensor, cost is too high, Er Qiejie
Structure is complicated, it is difficult to assemble.
In existing system, refrigerator air door driving motor is DC stepper motor, and stepper motor is as dynamical element, through gear
Decreasing transmission amplifies motor output torque, drives door-plate rotation；The forward and reverse rotation of motor is controlled by pulse sequence, realizes door
Plate opens/closes movement.Air door is installed in air duct in refrigerator, is controlled by temperature sensor.Temperature of refrigerating chamber is higher than setting
When value, control unit issues instruction, and air door is opened；After temperature reaches setting value, control unit issues instruction, and air door is closed, from
And it realizes and the cold airflow in air duct is controlled.
But after complete machine is completed, air door switch situation cannot see that, can not determine that air door is in and beat on or off
Closed state.So finding damper faults in time in order to more intuitive judgement throttle condition, it is ensured that refrigerator temperature control is more accurate, grinds
Hair, which will design a kind of electric flap feedback control system that understand that throttle opening, to have great importance.
Summary of the invention
For above-mentioned existing system problem, the present invention provides a kind of electric flap feedback control systems, in air door of air duct
It is equipped with Hall switch at position, the on-off signal feedback of Hall switch is shown on the display panel of refrigerator, can intuitively be known
Know throttle condition, finds damper faults in time, it is ensured that refrigerator temperature control is more accurate.
The present invention uses system schema below:
A kind of electric flap feedback control system, including channel air door, controller, display panel, Hall switch and with suddenly
You switch mutual corresponding flat thin magnet, and the channel air door includes air door door-plate and air door bracket, the Hall switch and magnet
Piece is separately positioned on the air door door-plate and air door bracket, and Hall switch and display panel are connected with controller respectively.
Further, the controller is single-chip microcontroller.
Further, two control lines one ground connection of the Hall switch, another connects single-chip processor i/o port.
In above-mentioned technical proposal, a Hall switch is installed above air door door-plate and on bracket, air door is opened Hall and opened
Shutdown is opened, and air door is closed Hall switch closure, and the control line one of Hall switch two is grounded one and is connected to single-chip processor i/o, finally
The on-off signal of Hall switch is shown on refrigerator display panel, throttle condition can be more intuitively determined, find wind in time
Door failure, it is ensured that refrigerator temperature control is more accurate.
Further, the channel air door is binary channels air door or single channel air door.
The invention has the advantages that:
Hall switch has the characteristics that contactless, low-power consumption, long life, response frequency are high, above air door door-plate
With one Hall switch of installation on bracket, air door is opened Hall switch and is disconnected, and air door is closed Hall switch closure, Hall switch two
Control line one ground connection one is connected to single-chip processor i/o, and the on-off signal of Hall switch is finally shown to refrigerator display panel
On, more intuitively determine throttle condition, find damper faults in time, it is ensured that refrigerator temperature control is more accurate.Its structure is simple, at low cost
It is honest and clean, it can be widely applied in refrigerator field.
Detailed description of the invention
Fig. 1 is the installation site structural schematic diagram of binary channels air door Hall switch；
Fig. 2 is the installation site structural schematic diagram of single channel air door Hall switch.
Wherein, 1 is Hall switch, and 2 be flat thin magnet.
Specific embodiment
