Problems solved by technology

[0002]In a large air-cooled refrigerator, there are usually many power components. In the case of user use, the state of self-inspection is not allowed, and in the prior art, there is no method for systematically inspecting each part in the refrigerator. Generally, each part must be individually inspected , this is very troublesome

Embodiment Construction

[0014] Refrigerator self-checking method of the present invention is such, as figure 1 As shown, a general refrigerator includes a CPU, a power supply, and the connection between the power supply and the CPU. It is characterized in that: the refrigerator also includes a detection port, and the detection port is set as a socket connected to the CPU. The power supply of the refrigerator is connected to the power detector. During the initial power-on, the level status of the input port, if the input is high, set the refrigerator to be in normal working state; if the input is low, set the refrigerator to be in the self-test state, and then add a short circuit on the row Plug in, the CPU input pin becomes low level, enters the self-test program, and then connects each power component sequentially, and observes whether the curve of the power detector shows a power curve consistent with the power component. If the power curve does not change, the power component If it is damaged, rep...

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 detectionmethod 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 [0001] The invention relates to a self-inspection method for electrical equipment, in particular to a self-inspection method for a refrigerator. Background technique [0002] In large-scale air-cooled refrigerators, there are often many power components. After the assembly is completed, we need to make a correct judgment on whether each component can operate correctly. However, in the case of user use, the self-test state is not allowed. And in the prior art, there is no method that can systematically detect each part in the refrigerator. Generally, each part will be detected separately, which is very troublesome. Contents of the invention [0003] The technical purpose of the present invention is to overcome the above defects and provide a self-inspection method for refrigerators that can find faulty parts very accurately by performing self-inspection on the original components of the refrigerator. [0004] The technical scheme of the self-checking method...
