When detection device detects that multiple blowers in fan assembly 3 break down, fan trouble detection device issues alarm signal,
Accident warning device can issue fault alarm prompting after receiving signal, such as accident warning device can be by the tool of fan assembly 3
Body fault condition is notified in the form of short message or in the form of voice to user, and then may remind the user that in fan assembly 3
Multiple blowers break down, and user can remind according to fault alarm and close air-conditioner outdoor unit 100, are then reported for repairment.Failure
Warning device improves the intelligence degree of air-conditioner outdoor unit 100, can effectively and timely remind user, is conducive to improve user
Usage experience.Simultaneously it is found that fan trouble detection device can pass through the event for the fan assembly that accident warning device will test
Barrier information passes to the controller of air-conditioner outdoor unit 100.
According to some embodiments of the present invention, fan trouble detection device is by detecting the revolving speed of each blower and making a reservation for turn
Whether speed is identical to judge whether blower breaks down.It follows that fan trouble detection device is by detecting each blower
Revolving speed and the desired speed of the default of air-conditioner outdoor unit 100 be compared to judge whether each blower breaks down.
When fan trouble detection device detects that the revolving speed of blower is identical as desired speed, then determine that the blower does not break down,
It operates normally.When fan trouble detection device detects the revolving speed of blower with corresponding desired speed difference, then the wind is determined
Machine breaks down.It follows that detection mode is simple, reliable.Optionally, fan trouble detection device is by detecting each blower
Revolving speed whether be located within the scope of desired speed and judge whether blower breaks down.
According to some embodiments of the present invention, fan trouble detection device is by detecting the operating current of each blower and pre-
Determine whether operating current is identical to judge whether blower breaks down.It follows that fan trouble detection device is to pass through detection
The predetermined work electric current of the default of the operating current and air-conditioner outdoor unit 100 of each blower is compared to judge each wind
Whether machine breaks down.When fan trouble detection device detect blower operating current it is identical as scheduled operating current when,
Then determine that the blower does not break down, operates normally.When fan trouble detection device detect the operating current of blower with it is right
When the predetermined work electric current difference answered, then determine that the blower breaks down.It follows that detection mode is simple, accurate.It is optional
Ground, fan trouble detection device judge by the way that whether the operating current of each blower of detection is located in predetermined work current range
Whether blower breaks down.
