Description
Technical field
The present invention relates to refrigerator art, circuit and a kind of refrigerator are detected in particular to a kind of master control borad fault.
Background technology
When at present, the problems such as refrigerator appearance is not freezed, a room illumination lamp does not work, compressor can not start, maintenance personal
The reason for needing to analyze refrigerator, the concrete reason that lookup refrigerator breaks down, and be directed to the failure is solved.Due to
The master control borad of refrigerator can control the operation that each is loaded, so when refrigerator breaks down, being just easy to be considered master control
Plate there is a problem, at present, typically all take the maintenance mode for changing master control borad to repair refrigerator.
But, have the drive circuit much loaded on master control borad, for example, the device such as resistance, electric capacity, change master control borad then without
Method knows which circuit or device occur in that failure on master control borad, thus bring difficulty to optimization design.In addition, this dimension
The mode of repairing can not accurately judge that out the basic reason that refrigerator breaks down, many failures (such as secondary refrigerant leakage, the refrigeration of refrigerator
Effect difference etc.) it can not be showed when refrigerator is just started working, it is necessary to can just be shown after refrigerator runs a period of time
Come, and these failures you be most likely not failure that master control borad goes wrong and produced, directly change master control borad and be likely to
Can not solve problem or it is simply temporary transient solve the problems, such as, cause these failures to there is also in the later stage.
In addition, in the related art, can also be to each device of master control borad, each driving when refrigerator breaks down
Circuit is detected, to judge whether it breaks down, and this mode is cumbersome and time consuming.
Therefore, how more rapidly and accurately to judge whether master control borad breaks down, as urgently to be resolved hurrily at present
Technical problem.
The content of the invention
The present invention is based on above mentioned problem, it is proposed that a kind of new technical scheme, can more rapidly and accurately sentence
Whether disconnected master control borad breaks down.
Therefore, it is an object of the present invention to propose a kind of master control borad fault detection circuit.
It is another object of the present invention to propose a kind of refrigerator, circuit is detected with above-mentioned master control borad fault.
To achieve the above object, the embodiment of first aspect present invention proposes a kind of master control borad fault detection circuit, uses
In refrigerator, including：On sense command receiver module, the master control borad for being arranged on the refrigerator, for receiving fault detect order；Dimension
Control panel is repaiied, the sense command receiver module is connected to, for receiving the event from the sense command receiver module
Hinder sense command, and open command or out code are sent to load driving circuits according to the fault detect order, to control
The working condition of the load driving circuits；The load driving circuits, are connected to the master control borad and the maintenance control panel,
Wherein, the working condition when the load driving circuits and the open command that sends of maintenance control panel or the closing
When instructing corresponding control result consistent, the master control borad fault-free, otherwise, the master control borad breaks down.
The master control borad fault detection circuit of embodiments of the invention, when whether the circuit that user wants detection master control borad occurs
During failure, fault detect order can be sent, sense command receiver module can just receive the fault detect order, then repair
Control panel just according to the fault detect order, controls being turned on and off for load driving circuits.If load driving circuits do not have
Failure, then load driving circuits will be turned on and off according to fault detect order, the work of such load driving circuits
State is just consistent with the corresponding control result of instruction that maintenance control panel is sent, and user is accomplished by other portions beyond master control borad
Part carries out inspection and maintenance.If load driving circuits break down, the working condition of load driving circuits is just controlled with maintenance
The corresponding control result of instruction that making sheet is sent is inconsistent, and such user is assured that master control borad breaks down, it is necessary to master
Control plate is repaired or changed.By above-mentioned technical proposal, it can more rapidly and accurately judge whether master control borad occurs
Failure, it is to avoid blindly repair and change the phenomenon of master control borad when refrigerator breaks down, so he more rapidly finds therefore
Hinder the basic reason occurred, saved maintenance time, be that user brings convenience, improve Consumer's Experience.

State.
The master control borad fault detection circuit 11 of embodiments of the invention, the open command sent according to maintenance control panel 112
The working condition of load driving circuits 113 is changed into connected state, or the out code sent according to maintenance control panel 112 will
The working condition of load driving circuits 113 goes off state, if the working condition of load driving circuits 113 can normally be cut
Change, it was demonstrated that master control borad does not have failure, otherwise prove that master control borad is faulty, it is necessary to repair and change.
According to one embodiment of present invention, load driving circuits 113 include：Load is indicated, master control borad and dimension is connected to
Control panel 112 is repaiied, when indicating that load sends instruction or stop indicating according to out code according to open command, master control borad is without reason
Barrier, otherwise, master control borad breaks down.
The master control borad fault detection circuit 11 of embodiments of the invention, according to the prompting for indicating load, can interpolate that load
Whether the working condition of drive circuit 113 can normally switch, for example, indicating that load is an indicator lamp, when load driving electricity
When the working condition on road 113 normally switches, indicator lamp, which will light, reminds user's master control borad fault-free, works as load driving circuits
When 113 working condition can not normally switch, indicator lamp will not light, and now master control borad, which breaks down, needs repairing and change.
In addition, indicating that the opening and closing of load and the working condition of load driving circuits 113 normally switch between improper switching
Corresponding relation, can according to the need for user oneself set, improve Consumer's Experience.
