Description
Technical field
The present invention and air-conditioning technical field, in particular to a kind of dirty stifled detection of outdoor machine of air-conditioner and self-cleaning method
And air conditioner.
Background technique
It is more severe that air-conditioner outdoor unit installs and uses environment, is easy because of dust, leaf etc. accidentally enters condenser fin
In or the foreign matters such as polybag be adsorbed on condenser, cause outdoor unit dirty stifled.The dirty stifled outdoor unit that will affect of outdoor unit radiates,
Air conditioner refrigeration effect is caused to decline, efficiency reduces, and causes the waste of the energy.And if outdoor unit is dirty stifled serious, in outdoor environment temperature
Spend it is higher when, also result in exhaust it is excessively high, influence unit reliability and service life.And home-use outdoor machine of air-conditioner is typically mounted at
Equipment platform is hung on exterior wall, and user tends not to notice the dirty stifled situation of outer machine.
Summary of the invention
Problems solved by the invention is to provide a kind of dirty stifled detection of outdoor machine of air-conditioner and self-cleaning method, and it is reliable to increase unit
Property and service life.
To solve the above problems, the present invention provides a kind of dirty stifled detection of outdoor machine of air-conditioner and self-cleaning method, comprising:
External disk temperature Tc, outer ring temperature T0 and delivery temperature Tp and outer blower when by obtaining air conditioner refrigerating operation turn
Fast S judges the outer dirty stifled situation of machine condenser；
If judging, outer machine condenser is blocked up there are dirty, by transformation cooling and warming mode and is adjusted outer blower fan turning, is made cold
Condenser carries out automatically cleaning.
Thus, it is possible to which it is dirty stifled to have temperature sensor detection outdoor unit by oneself by air-conditioner set, and automatically cleaning is carried out, intelligence is high
Effect, being capable of energy saving and promotion user experience, increase air-conditioner set reliability and service life.
In some embodiments, external disk temperature Tc, the outer ring temperature T0 and row by obtaining when air conditioner refrigerating operation
