Abstract
The invention relates to a self detection method of electrical equipment, in particular to a refrigerator self detection method, which can be used for extremely and accurately find fault parts by the self detection of original parts of the refrigerator. The refrigerator comprises a CPU, a power supply and a detection port, wherein the CPU is connected with the power supply, the detection port is provided with a socket connected with the CPU, and the power supply of the refrigerator is connected with a power detection instrument. The refrigerator self detection method comprises the following steps: firstly, setting an initial power-on time and inputting a port level state; setting the refrigerator to be in a normal working state if a high level is inputted and setting the refrigerator to bein a self detection state if a low level is inputted; and then judging whether the parts are normal or not according to the display of the power detection instrument. The refrigerator self detection method is easy and practical, has very intuitive fault detection rate and can be widely used in the fields of refrigerator manufacture and maintenance.
Description
Technical field
The present invention relates to a kind of self checking method of electric equipment, specifically, relate to a kind of a kind of self checking method of refrigerator.
Background technology
In the large-sized wind cooling refrigerator, often power component is many, after assembling is finished, can we will make correct judgement by correct operation to each parts, and in the situation that the user uses, do not allow to occur again the state of self check, and just do not have in the prior art a kind of method that can systematically detect each part in the refrigerator at all, generally be to detect separately each part separately, bother so very much.
Summary of the invention
Technical purpose of the present invention is to overcome above defective, provides a kind of original components and parts to refrigerator to carry out self check, can find very exactly a kind of self checking method of the refrigerator of failed part.
The technical scheme of the self checking method of refrigerator of the present invention is such: refrigerator comprises CPU, power supply, power supply is connected with CPU, it is characterized in that: refrigerator comprises that is also detected a mouth, detect mouth and be set to a socket that is connected with CPU, the power supply of refrigerator connects power detecting instrument, during at first setting powers on for the first time, and the input port level state, if be input as high level, set refrigerator and be in normal operating conditions; If the low level of being input as is set refrigerator and is in the self check state, then carry out the following step:
1. add that in socket a short circuit is slotting, the CPU input pin becomes low level, enters self-check program;
2. then connect in turn each power component, whether the curve of observing power detecting instrument shows the powertrace that conforms to power component;
3. if the powertrace of step 2 conforms to the power of power component, enter step 4, if do not change, then this power component damages, and keeps in repair or changes;
4. force reefer refrigeration a period of time, observe checkout equipment temperature of refrigerating chamber curve and whether descend, if do not descend or downtrending and normal diversity ratio larger, show that the reefer refrigerating circuit has fault; Normal if descend, show that the reefer refrigerating circuit is normal, enter step 5:
5. the operation identical with step 4 carried out in the refrigerating chamber refrigerating circuit.
The self checking method of refrigerator of the present invention, the method simple possible, the fault recall rate is more directly perceived, can be widely used in the production of refrigerator and maintenance field.
Description of drawings
Fig. 1 is the electric current structural representation of refrigerator self checking method of the present invention;
Fig. 2 is the powertrace synoptic diagram of embodiments of the invention.
Embodiment
Refrigerator self checking method of the present invention is such, as shown in Figure 1, general refrigerator all comprises CPU, power supply, and power supply is connected with CPU, it is characterized in that: refrigerator comprises that is also detected a mouth, detect mouth and be set to a socket that is connected with CPU, the power supply of refrigerator connects power detecting instrument, during at first setting powers on for the first time, and the input port level state, if be input as high level, set refrigerator and be in normal operating conditions; If the low level of being input as, set refrigerator and be in the self check state, then add that in socket a short circuit is slotting, the CPU input pin becomes low level, enter self-check program, then connect in turn each power component, whether the curve of observing power detecting instrument shows the powertrace that conforms to power component, if powertrace does not change, then this power component damages, keep in repair or change, if the power of the variation of powertrace and power component conforms to, then carry out again the detection of reefer refrigerating circuit or refrigerating chamber refrigerating circuit, as shown in Figure 2, after refrigerator entered the self check state, we connected in turn power component.Suppose to have the power device of 4 1W, we connect first the device of first 1W, we demonstrate the curve of 1W at power detection device so, connect second power device behind the 5s, we demonstrate the curve of 2W at power detection device so, connect the 3rd power device behind the 5s, and we demonstrate the curve of 3W at power detection device so, connect in turn, we can obtain the power shown in the figure two.If one is made a mistake, the position that we break down very intuitively.
After the power self check finishes, we force refrigerator to walk separately reefer refrigeration 20 minutes, whether we also can view refrigerator chamber refrigerated storage temperature curve at checkout equipment and descend so, if do not descend or downtrending and normal diversity ratio larger, the road that we just can judge the refrigeration of refrigerator freezes whether fault is arranged.
Then our closing cold room, force refrigerator to walk separately freezing refrigerating circuit, whether we also can view the freezer compartment of refrigerator temperature curve at checkout equipment and descend so, if do not descend or downtrending and normal diversity ratio larger, the freezing road that we just can judge refrigerator freezes whether fault is arranged.
Claims (2)
1. a kind of self checking method of a refrigerator, refrigerator comprises CPU, power supply, power supply is connected with CPU, it is characterized in that: refrigerator comprises that is also detected a mouth, detects mouth and is set to a socket that is connected with CPU, and the power supply of refrigerator connects power detecting instrument, during at first setting powers on for the first time, the input port level state if be input as high level, set refrigerator and is in normal operating conditions; If the low level of being input as is set refrigerator and is in the self check state, then carry out the following step:
1, add that in socket a short circuit is slotting, the CPU input pin becomes low level, enters self-check program;
2, then connect in turn each power component, whether the curve of observing power detecting instrument shows the powertrace that conforms to power component;
If 3, the powertrace of step 2 conforms to the power of power component, enter step 4, if do not change, then this power component damages, and keeps in repair or changes;
4, force reefer refrigeration a period of time, observe checkout equipment temperature of refrigerating chamber curve and whether descend, if do not descend or downtrending and normal diversity ratio larger, show that the reefer refrigerating circuit has fault; Normal if descend, show that the reefer refrigerating circuit is normal, enter step 5:
5, the operation identical with step 4 carried out in the refrigerating chamber refrigerating circuit.
