Description
Technical field
The present invention relates to a kind of air-conditioner and method of operating thereof.
Background technology
After air-conditioner used a period of time, the screen pack of indoor set and outdoor heat exchanger all can have dust stratification in various degree, and this dust stratification also can produce mould when influencing the air-conditioner main performance, directly influence user's health.
For the air-conditioner that dust arrester is not set, the consumer generally not too notes regular check and cleaning.For the air-conditioner that is provided with dust arrester, the control for dust arrester generally all is non intelligent at present, generally adopts following two kinds of methods.
A kind of is by remote controller or by the unlatching of key control dust arrester or close by the user.The shortcoming of this mode is whether only can not accurately judge air-conditioner with user's sensation needs dedusting, so dust arrester can not give play to effect in time, can not fundamentally solve the dust removal problem of air-conditioner.Another kind is dust arrester and air-conditioner synchronous operation, though this mode has solved dust removal problem, dust arrester can also move when air-conditioner does not need dedusting always, the waste electric energy.
Chinese patent literature CN 201103967Y discloses a kind of automatic dedusting air-conditioner on August 20th, 2008, this air-conditioner includes at least one indoor flue dust induction installation that is arranged on, this flue dust induction installation is electrically connected with controller, controller is electrically connected with dust arrester, controller also is connected with the IAQ data display unit, and controller is connected with dust arrester with feedback port by driving port.Air-conditioner can detect and start automatically or close dust arrester according to the dirty degree of room air.Though this air-conditioner can be realized automatic dedusting, therefore not high the and inefficacy easily again of flue dust induction installation complex structure, the precision that it adopts is necessary to do further improvement and perfect.
Summary of the invention
Purpose of the present invention aims to provide a kind of simple and reasonable, flexible operation, cost of manufacture is low, operating cost is low, applied widely air-conditioner and method of operating thereof, to overcome weak point of the prior art.
A kind of air-conditioner by this purpose design comprises MCU, it is characterized in that being provided with the velocity sensor that detects wind speed at the return air inlet of air-conditioner, and velocity sensor is electrically connected with MCU, and MCU also is connected with display unit and buzzer.
A kind of method of operating of air-conditioner is characterized in that may further comprise the steps:
Step 1, after indoor machine of air-conditioner is opened, the velocity amplitude of the detected return air inlet of the automatic reading speed sensor of MCU;
Step 2 judges that whether velocity amplitude is less than setting value; When it is set up, enter step 4, when it is false, enter step 3;
Step 3, indoor machine of air-conditioner continues operation by previous status;
Step 4, display unit shows dust-full, and opens buzzer prompting user and clean.
Another kind of air-conditioner comprises dust arrester and MCU, it is characterized in that being provided with the velocity sensor that detects wind speed at the return air inlet of air-conditioner, and velocity sensor is electrically connected with MCU, and dust arrester is electrically connected with MCU, and MCU also is connected with display unit.
The method of operating of another kind of air-conditioner is characterized in that may further comprise the steps:
Step 1, after indoor machine of air-conditioner is opened, the velocity amplitude of the detected return air inlet of the automatic reading speed sensor of MCU;
Step 2 judges that whether velocity amplitude is less than setting value; When it is set up, enter step 4, when it is false, enter step 3;
Step 3, indoor machine of air-conditioner continues operation by previous status;
Step 4, display unit shows dust-full, and opens the automatic dedusting of dust arrester.
In the described dust arrester opening process, when dust arrester broke down, dust arrester fed back to MCU with fault-signal, and MCU then closes dust arrester.
The present invention is provided with the velocity sensor that detects wind speed by the return air inlet at air-conditioner, velocity sensor is electrically connected with MCU, the precision height and the working stability of velocity sensor are reliable, can in time remind the user that air-conditioner is cleaned, perhaps, can in time control dust arrester air-conditioner is cleaned automatically, make air-conditioner when assurance is created health, comfortable environment for the user, save operation energy consumption, reduce operating cost.
The present invention is not only applicable to the air-conditioner with dust arrester, and is applicable to the air-conditioner of not being with dust arrester, and it has simple and reasonable, flexible operation, cost of manufacture is low, operating cost is low, advantage of wide range of application.
