Row.
The invention also includes: before the mould quantity in detection air-conditioning air output is detected, judged whether lower than the first limit value；
If so, cleaning air-conditioning, if it is not, then continuing to execute the corresponding steps of mould quantity in detection air-conditioning.
The mode of the cleaning air-conditioning is to be cleaned using the gas after pressurized, heated to air-conditioning heat exchanger.
After cleaning air-conditioning in the present invention, the mould quantity or air output in air-conditioning are detected, judges whether to need to clean again；
If so, air-conditioning is cleaned again, if it is not, air-conditioning operates normally；
The mould quantity or air output in air-conditioning are detected again, judges whether to need to clean again, need to tear machine open if so, reminding
Cleaning；If it is not, air-conditioning operates normally.
The mould quantity or air output in air-conditioning are detected after air-conditioning startup self-detection.
First limit value is 500 m3/h, and second limit value is 10.
The present invention also proposes that one kind is adopted and carries out self-cleaning air-conditioning with the aforedescribed process.
Air-conditioning includes: on the partition being arranged in air-conditioning and spray head is directed at the nozzle of heat exchanger, drives the electricity of nozzle rotation
Machine, one end connection transfer pipeline of nozzle, the air pump of the connecting conveying pipe road other end, the heater of heated transportation pipeline, use
In the first sensor of detection mould quantity.
Further, further include second sensor for detecting air output.
Preferably, the motor is stepper motor.
The rotation angle of the nozzle is 120 degree.
The center for being fixed on middle partition of the nozzle.
Compared with prior art, the present invention detects air output and mould quantity by sensor group, if simultaneously above limit
Value, then cleaned using heat exchanger of the high temperature and pressure hot-air to air-conditioning.To avoiding mould excessive number in air-conditioning
Influence the health of user.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is flow chart of the invention；
Fig. 2 is structure diagram of the invention.
Specific embodiment
As shown in Figure 1, the invention proposes a kind of self cleaning methods of air-conditioning, comprising: survey air-conditioning by first sensor
Interior mould quantity judges whether to be higher than the second limit value；If so, illustrating the mould excessive number in air-conditioning, air-conditioning, benefit are cleaned
It is cleaned with heat exchanger of the high temperature and pressure hot-air to air-conditioning, if it is not, then illustrating that mould quantity is normal, closes automatically cleaning mould
Formula, air-conditioning operate normally；It can prevent the mould excessive number in air-conditioning and influence the health of user.
The invention also includes air output is detected before the mould quantity in detection air-conditioning, judge whether lower than the first limit value；
If so, may be that dust in air-conditioning excessively influences outlet air, air-conditioning is cleaned, if it is not, then illustrating the ash inside air-conditioning
Dirt quantity does not influence outlet air, then detects to the mould quantity of air-conditioning.Judge whether to be higher than the second limit value；If so, cleaning is empty
It adjusts, if it is not, air-conditioning operates normally.By detecting the air output of air-conditioning, air-conditioning is cleaned, the effect of air-conditioning is further improved
Energy.Wherein the first limit value can be set as 500 m3/h, and the second limit value can be set as 10.
In the present invention, air-conditioning heat exchanger is cleaned using the gas after pressurized, heated, specific cleaning step is to open
Dynamic air pump and heater；Whether the pressure value of detection air pump reaches the first preset value, and whether the temperature for detecting heater reaches
To the second preset value, if so, opening nozzle and stepper motor clean air-conditioning heat exchanger.If it is not, continuing to detect, know
Road is met the requirements, then is cleaned.Wherein the second preset value can be set as 100 DEG C.It is also effective using the gas of high temperature and pressure
Mould and dust are removed, the cleanliness of air-conditioning is improved.
The present invention detects air output or detects the mould quantity in air-conditioning, see that cleaning is after the completion of executing cleaning air-conditioning
It is no to reach effect, if to need to clean again；
If so, air output or mould quantity is not still up to standard, air-conditioning is cleaned again；If it is not, then illustrating up to standard, air-conditioning is just
Often starting；
After having cleaned air-conditioning, air output is detected again or detects the mould quantity in air-conditioning, detects whether to need to clean again；If
It is to illustrate that cleaning has been unable to reach effect, prompting needs to tear open machine cleaning, avoids wasting；If it is not, then explanation has reached needs
Effect, closes automatically cleaning mode, and air-conditioning normally starts.
The mould quantity or air output in air-conditioning are detected in the present invention, after air-conditioning startup self-detection, and repeated detection is avoided to waste
Electric energy.
As shown in Fig. 2, the present invention also proposes a kind of air-conditioning, the above method is used, comprising: nozzle 1, motor 2, transfer pipeline
3, heater 5, air pump 4 and sensor, nozzle 1 are arranged on the middle partition 6 of air-conditioning, and spray head is directed at heat exchanger 7, motor 2
Be arranged close to nozzle 1, rotation can be driven, change jet hole direction can each place of heat exchanging device 7 cleaned,
3 one end of transfer pipeline connects nozzle 1, the air pump 4 of other end connection, and through-hole air pump 4 is blown toward one end of nozzle, heater
5 are attached on transfer pipeline 3 in back-shaped, and heated transportation pipeline 3 makes jet hole spray the gas of high temperature and pressure, dispel dust and mould
Bacterium excludes it outside air-conditioning, and wherein sensor includes first sensor and second sensor, and second sensor can detect outlet air
Amount, first sensor can detect mould quantity.
In the present invention, most heat exchanging device cleanings twice, if still not meeting limit value, are prompted to need to tear open machine cleaning, be kept away
Exempt to waste.
In the present invention, motor is stepper motor, makes nozzle that swing be repeated.Wherein the rotation angle of nozzle can be set
It is 120 degree, covers the setting area of heater.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
