With reference to Fig. 2 a and Fig. 2 b, the air-conditioner of the embodiment of the present invention includes:Evaporator 1, water tank 2, tank 3, add water water pump 4
With filler pipe 5, the bottom of the evaporator 1 is provided with drip tray 11, and the water tank 2 is connected with the tank 3, the drip tray
11 are provided with delivery port 12 near one end of tank 3, and the water outlet 12 is connected with outlet pipe 13, and the outlet pipe 13 connects described
Drip tray 11 and the tank 3, the water pump 4 that adds water are arranged in the tank 3, the filler pipe 5 and the water pump 4 that adds water
Between connected by triple valve 14, the triple valve 14 is also associated with drainpipe 15, during practice, by triple valve
14 control, the control connection filler pipe 5 of triple valve 14, it is also possible to which, by the control to triple valve 14, control triple valve 14 is connected
Drainpipe 15.By the switching of triple valve 14, realization adds water the connection filler pipe 5 of water pump 4 to the water filling of evaporator 1, and switches to
Added water the communicated drainage pipe 15 of water pump 4, and water is discharged outside air-conditioner.
Refrigeration mode is turned on into control compressor, the coil temperature of evaporator 1 is constantly reduced, opened in control compressor
Open while into refrigeration mode, the control water pump 4 that adds water is opened, control triple valve 14 is switched to and connected with filler pipe 5, and add water water
Water in tank 3 is squeezed into evaporator 1 by pump 4 by filler pipe 5.
Preferably, the filler pipe 5 is provided with shower nozzle against one end of evaporator 1, by shower nozzle spray water to evaporator
1, the contact area of water and evaporator 1 is improved, by spraying into the cleaning dynamics increased to evaporator 1.It is understood that described
Filler pipe 5 can also be middle part or middle and lower part the position water spray against the evaporator 1, not be the upper end of opposite evaporator 1
During water spray, the shower nozzle of the connection of filler pipe 5 needs the setting of fountain height.Specifically it is set to, the injection flow rate near upper end is more than lower end
Injection flow rate.When evaporator 1 is cleaned, control compressor is opened, and the water pump 4 that controls to add water periodically open first it is default when
Between, stopping the second Preset Time, the water of the water pump 4 that adds water squeezes into evaporator 1 by filler pipe 5.That is, a cycle is the water pump that adds water
4 open operation the very first times, after unlatching reaches the very first time, the second time out of service, it is out of service reach second when
Between after, into second period, first open the very first time, then the second time out of service, so repeatedly until terminating to add water.It is logical
Cross the control water pump 4 that adds water first to open the very first time, the second time out of service, within this cycle, the water pump 4 that adds water sprays into evaporation
Water on device 1 just flows into the bottom of evaporator 1, without flowing into drip tray 11, causes the wasting of resources.The very first time and
Second time pre-set, and the rotating speed according to humidity, temperature, air conditioning operating mode and the water pump that adds water in current environment sets
One time and the value of the second time.By the value for setting the very first time and the second time, it is ensured that the water pump 4 that adds water sprays into evaporator 1
Water be entirely localized on evaporator 1.Preferably, early stage is opened in compressor, the very first time sets shorter, opened in compressor
For a period of time, for example, after 5 minutes or 8 minutes, evaporator temperature is relatively low, water start on evaporator 1 freeze, now first when
Between can set long, can 20s long or 30s etc. with respect to compressor unlatching early stage;Or the water pump 4 that adds water is opened in compressor
The rotating speed of early stage is less than the rotating speed in unlatching a period of time.
Step S30, icing on an evaporator meet it is pre-conditioned after, control compressor enters heating mode, will steam
The ice-out tied on hair device flows into drip tray, cleans evaporator;
Specifically, with reference to Fig. 3, judge the icing on evaporator meet it is pre-conditioned including:

In cleaning process, the control continual communication of triple valve 14 filler pipe 5, and the water in drip tray 11 is through the He of delivery port 12
Outlet pipe 13 flows into tank 3, and the water flowed down from evaporator 1 that control drip tray 11 is collected is not expelled to outside air-conditioner.Water receiving
Disk 11 collects the cleaning water of evaporator 1, and flowing into tank 3 by delivery port 12 recycles, and tank 3 is again flowed into, by the water that adds water
The water that pump 4 and filler pipe 5 will flow into inflow tank in drip tray 11 squeezes into evaporator evaporation to the wash cycles of evaporator 1, saves
Water resource.
Step S50, after wash cycles reach preset times, controls triple valve communicated drainage pipe, by the water in drip tray
Drain into outside air-conditioner.
The preset times can be that 1 time or 2 times or 3 are inferior, and the water of early stage cleaning evaporator 1 is messy, it is impossible to do too
Multiple wash cycles, not so cleaning performance is poor.After wash cycles reach preset times, triple valve communicated drainage pipe is controlled,
Water in drip tray 11 is drained into outside air-conditioner, not recycling water cleaning evaporator 1.Specifically, in drip tray 11
Water drains into tank 3 by its delivery port 12 and outlet pipe 13, then the water in tank is passed through into the row of drainpipe 15 by the water pump 4 that adds water
To air-conditioner.Using one water pump 4 is added water by triple valve 14 to realize being sprayed water to evaporator 1 and by inside air-conditioner
Clean the filthy water of evaporator 1, material-saving part, reduces cost.
Further, according to step S10, step S20, step S30, step S40 and step S50 wash cycles evaporator 1;
After predetermined threshold value is reached according to step S10, step S20, step S30, step S40 and step S50 wash cycles number of times, control
The communicated drainage pipe 15 of triple valve 14, by the water emptying in drip tray 11 and tank 3, terminates the cleaning of evaporator 1.The default threshold
Value can be that 5 times or 8 are inferior, after wash cycles evaporator 1 reaches predetermined threshold value, it is meant that evaporator 1 is cleaned up, close
Compressor, switching three-way valve 14 to drainpipe 15, by the water emptying in drip tray 11 and tank 3, completes the cleaning behaviour of evaporator 1
Make.
It is understood that after wash cycles number of times reaches predetermined threshold value, the communicated drainage pipe 15 of triple valve 14 is controlled, will
Water emptying in drip tray 11 and tank 3, terminates the cleaning of evaporator 1.The state of compressor is obtained, is refrigeration in compressor
When, control compressor enters heating mode, melts the ice tied on evaporator 1, after ice melts completely, close compressor;
When compressor is the state for heating, the state for being frozen on evaporator 1 is obtained, when ice melts completely, close compressor,
Freeze when not melting completely, compressor is continued to run with until closing after the thawing completely that freezes.By compressor state and steaming
The situation of ice-out rationally controls the closing of compressor on hair device 1.
In one embodiment, or after the duration of wash cycles reaches certain hour, close compressor is cut
Triple valve 14 to drainpipe 15 is changed, by the water emptying in drip tray 11 and tank 3.The certain hour can be 30 minutes or 45
