Abstract
The utility model designs a 160B refrigerator controller service life testing circuit which belongs to the field of testing circuits of household electric products; a two-phase utility power supply passes through a power switch and a fuse, and is accessed to a power interface of a CN1 interface of a 160B controller, a power cord is divided into 5 circuits of power supplies which are accessed to a compressor interface and two valve interfaces of the CN1 interface as well as a fan interface and a defrosting interface in a CN2 interface after being respectively and serially connected with indicator lamps; the indicator lamps are connected on the positive and negative voltage interfaces of an LED lighting power supply of a CN4 interface after being serially connected with a resistor, and an analog load resistor is paralelly connected on a +5V power supply of the CN4 interface; a +12V power supply is parallelly connected with two resistors as the analog load resistors; and a switch control interface of the CN4 interface is parallelly connected with a start button. The 160B refrigerator controller service life testing circuit uses the visual signals of the indicator lamps to simulate the action of corresponding relays, is direct and reliable and has high recognizability; the loads are added on the output ends of all the power supplies so as to realize full-load test, further meet the use conditions of finished refrigerator products, enhance the strength and direction of the service life tests, and improve the quality grade of the qualified products.
Description
Technical field
The utility model relates to a kind of application circuit, particularly a kind of refrigerator controller that is applied to the 160B model.
Background technology
Present household electrical appliances all adopt Based Intelligent Control, have just produced corresponding controller, and this quasi-controller adopts the form of single circuit board more, and a plurality of peripheral circuit interfaces are arranged.The quality of controller directly influences the quality of entire equipment, so particularly important for the quality testing of controller.
The control panel of 160B model is a control panel commonly used in the refrigerator, has 3 road external interfaces to connect the control corresponding actuating of relay on this control panel, finishes corresponding function, and this three road interface is: CN1 is power supply, compressor, pipeline valve interface; CN2 is blower fan and defrost control; CN4 be LED illumination ,+5V and+output of 12V low tension.The detection main contents of the control panel of this model are carried out function and life test to above-mentioned 3 road external interfaces exactly.
Summary of the invention
The utility model is intended to invent a kind of life test circuit that model is the refrigerator controller of 160B that is applied to, and can test down the Board Under Test full load condition, and test event is complete, directly perceived.
The utility model circuit two-phase mains supply inserts the power interface of the CN1 interface of 160B beta version behind power switch and fuse, power lead is told 5 road power supplys, connect respectively behind the pilot lamp, insert fan interface and defrost interface in the compressor interface of CN1 interface, two valve interfaces, the CN2 interface; Be connected on after pilot lamp and the series connection of resistance on the generating positive and negative voltage interface of LED mains lighting supply of CN4 interface, other have fictitious load resistance be connected in parallel on the CN4 interface+the 5V power supply on; Two resistance in parallel are as fictitious load resistance on the+12V power supply; Start key in parallel on the switch control interface of CN4 interface.
The pilot lamp that connects on this use new LED mains lighting supply preferably uses light emitting diode.
Use the refrigerator controller of this circuit test 160B, utilize the visual signal simulation corresponding relays action of pilot lamp, intuitive and reliable, identification is high; Increasing in each power supply output has load, realizes the full load test, more meets the operating position of refrigerator finished product, has strengthened the intensity and the specific aim of life test, has improved the quality grade of specification product.
Description of drawings
Fig. 1, the circuit connection diagram that this use is novel.
Embodiment
As shown in Figure 1, the main control chip of tested 160B model control panel is the paster chip S3F9498XZZ-32SOP of Samsung, zero-power line L end and live wire N that two-phase power supply is connected to the CN1 interface of tested controller after by power switch K1 and fuse F1 hold, be in series with pilot lamp on the compressor relay interface COMP end of CN1 interface, get from power supply; Also be connected to pilot lamp respectively on two valve relay interface V1, V2 ends of CN1 interface, the blower fan relay end Fan end of CN2 interface and the defrost relay interface HS end, get from power lead.The LED power interface LED+ of the CN4 interface of tested controller and LED-end are parallel with the LED test section that light emitting diode D1 and resistance R 1 are in series.Resistance R 2 in parallel on Switching Power Supply+5V end, the parameter of R2 is 12 Ω 5W; Two resistance R 3 in parallel, R4 on the+12V end, the parameter of resistance R 3 and R4 is 68 Ω 5W.The switch terminals of CN4 interface also has a start key SW1.
The utility model circuit can cooperate software, controls frequent, the balanced break-make of each interface, improves the effect of life test.
