Abstract
The utility model discloses a failure detection device for an outdoor fan of an air conditioner. The failure detection device for the outdoor fan of the air conditioner comprises an outdoor coil (3), the outdoor fan (4), a throttle device (5), a controller (6), a display screen (7), an outdoor coil temperature sensor (7) and an outdoor ambient temperature sensor (8), wherein the outdoor coil temperature sensor (7) and the outdoor ambient temperature sensor (8) are connected with the controller (6); the outdoor fan (4) is a fan driven by an alternating-current power supply; and the controller (6) judges whether the outdoor fan (4) fails according to the difference between temperature values detected by the outdoor coil temperature sensor (7) and the outdoor ambient temperature sensor (8), and outputs failure information to the display screen (7). When a user finds out that the outdoor fan of the air conditioner fails, the user can directly tell after-sales staff the failure information, and the after-sales staff can also directly judge why the air conditioner cannot play a cooling role through the failure information, so that the after-sales staff can repair the air conditioner in a targeted mode.
Description
Technical field
The utility model relates to a kind of Fail detecting apparatus for outdoor fan of air-conditioner, belongs to after sales service or the detection facility of air-conditioning.
Background technique
At present, in a single day outdoor fan of air-conditioner breaks down and is difficult to detect.Even correlative study is arranged, also only limit to the outdoor fan of air-conditioner of the DC electrical source driving of feedback.
Yet present outdoor fan of air-conditioner is still take the ac power supply driving as main.Because this kind outdoor fan of air-conditioner is the no signal feedback, in case damage produces fault, air-conditioning can not normally use, the after-sales service personnel just can only arrive in the user family could judge failure cause after the start observation.If after the after-sales service personnel complete detection, judge it is the outdoor fan of air-conditioner fault really, also will return and get related accessory and carry out air-conditioning maintenance (large and be non-easy worn part because of the outdoor fan of air-conditioner volume and weight, so seldom carry) again, operating process is comparatively complicated.
The model utility content
The utility model is to solve the fault detection problem of above-mentioned outdoor fan of air-conditioner.
For this reason, the utility model provides a kind of Fail detecting apparatus for outdoor fan of air-conditioner, comprise outdoor fan, controller, display screen, it is characterized in that: also comprise the outdoor coil pipe used temperature transducer and the outdoor environment temperature sensor that are connected with above-mentioned controller; Above-mentioned outdoor fan is the blower fan that ac power supply drives; Above-mentioned controller is judged whether fault of outdoor fan according to the difference of outdoor coil pipe used temperature transducer and the detected temperature value of outdoor environment temperature sensor, and with fault message output on above-mentioned display screen.
Evidence, during the air-conditioning normal operation, the temperature difference of outdoor coil pipe used temperature and outdoor environment temperature is generally 3～7 ℃.Air-conditioning moves under refrigeration mode or dehumidification mode does not have refrigeration, if cause because of the outdoor fan fault, air-conditioning is after unlatching a period of time, and outdoor coil pipe used temperature meeting is risen rapidly, increased the temperature difference when being far longer than above-mentioned normal operation with the temperature difference meeting of outdoor environment temperature is quick.
Fail detecting apparatus of the present utility model utilizes above-mentioned principle exactly, by outer coil pipe temperature transducer and the outdoor coil pipe used temperature of outdoor environment temperature sensor Real-Time Monitoring (hereinafter to be referred as the T dish) and outdoor environment temperature (hereinafter to be referred as the T ring), when T Pan – T ring〉set temperature value and keep the set time value, just judge outdoor fan of air-conditioner and break down, and fault message is exported on display screen.Like this, the user can directly tell fault message after sale personnel when finding the outdoor fan of air-conditioner fault; Personnel also can directly judge the reason that air-conditioning does not freeze by fault message after sale, thereby maintenance shoots the arrow at the target.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 the utility model is used for the structure principle chart of the Fail detecting apparatus of outdoor fan of air-conditioner;
The operational flowchart of Fig. 2 Fail detecting apparatus shown in Figure 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the Fail detecting apparatus that is used for outdoor fan of air-conditioner of present embodiment comprises indoor set 1, compressor 2, outdoor coil pipe used 3, outdoor fan 4, throttling arrangement 5, controller 6, display screen 7, outdoor coil pipe used temperature transducer 7, outdoor environment temperature sensor 8.Wherein, outdoor coil pipe used temperature transducer 7 and outdoor environment temperature sensor 8 are connected with above-mentioned controller 6; The blower fan that outdoor fan 4 drives for ac power supply; Controller 6 is judged whether fault of outdoor fan 4 according to the difference of outdoor coil pipe used temperature transducer 7 and outdoor environment temperature sensor 8 detected temperature values, and with fault message output on above-mentioned display screen 7.
The compressed machine 2 of gas coolant is collapsed into high temperature and high pressure gas, flows to outdoor coil pipe used 3(heat exchanger), outdoor fan of air-conditioner 4 is opened, by outdoor coil pipe used 3 and the outdoor environment air carry out heat exchange, discharge from indoor heat; Refrigerant becomes high temperature high pressure liquid, through throttling arrangement 5 as throttling capillaceous, becomes the low-temp low-pressure gas-liquid mixture by high temperature high pressure liquid, and refrigerant arrive indoor set 1 again, and the interior heat of absorption chamber is got back to compressor 2 after becoming the gas of low-temp low-pressure.
The operating process of this embodiment's the Fail detecting apparatus that is used for outdoor fan of air-conditioner is as shown in Figure 2:
Step 1: initialization;
Step 2: the air-conditioning start enters refrigeration mode or dehumidification mode;
Step 3: judge that whether operation is above 3 minutes? if not, continue to judge; If then enter next step;
Step 4: detect outdoor coil pipe used temperature T dish, finish detection after;
Step 5: sensing chamber's external environmemt temperature T ring, finish detection after;
Step 6: judge that T Pan – T ring is greater than 30 ℃? if not, then return step 4; If then enter next step;
Step 7: whether the above-mentioned temperature difference kept for 10 seconds if not, then returned step 4; If then enter next step;
Step 8: newspaper AC motor fault; Namely show corresponding failure code by display screen;
Step 9: finish
The Fail detecting apparatus that is used for outdoor fan of air-conditioner of present embodiment, controller 6 detects outdoor coil pipe used temperature T dish by outdoor coil pipe used temperature transducer 7, comes sensing chamber's external environmemt temperature T ring by outdoor environment temperature sensor 8.When outdoor fan of air-conditioner 4 had fault, outdoor judgement 3 was because of can not be effectively and outdoor heat exchange, air-conditioning after start a period of time temperature raise fast, thereby cause outdoor environment temperature (T ring) and the increase of outdoor coil pipe used temperature (T dish) difference.When T dish – T ring〉30 ℃ and keep 10s and air conditioner available machine time during 3min, judge the outdoor fan of air-conditioner fault, and showing that with code form screen display is to inform user or personnel after sale.
More than be one of mode of execution of the present utility model, for those skilled in the art, do not spend performing creative labour, on the basis of above-described embodiment, can do multiple variation, can realize the purpose of this utility model equally.But this variation obviously should be in the protection domain of claims of the present utility model.
