Step S10, when evaporator is cleaned, control compressor turns on into refrigeration;
In the present embodiment, after air-conditioner unlatching, the parameter set according to acquiescence or user is run.Needing to steaming When hair device is cleaned, control enters evaporator cleaning model.The control can include into evaporator cleaning model:1) receive and steam Hair device clear instruction, evaporator cleaning model is entered according to evaporator clear instruction;2) total operation duration of air-conditioner is obtained, Total operation duration reach preset duration (100 hours or 120 hours etc., according to demand and ambient As, for example, ambient dust ratio Larger, then preset duration setting is shorter, is 80 hours or 90 hours etc., and few in ambient dust, then preset duration is set It is longer, be 120 hours or 130 hours etc.) when, automatically into evaporator cleaning model.When evaporator cleaning model is entered, Control compressor turns on into refrigeration mode, and indoor fan is with the shelves operation or out of service of low wind.
Step S20, control triple valve is switched to and connect with filler pipe, and the water pump periodically unlatching first that controls to add water is pre- If the time, stop the second Preset Time, the water of the water pump that adds water squeezes into evaporator by filler pipe;
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:
Step S31, after the number of run of the water pump predetermined period that adds water reaches preset times, or when refrigerating operaton is default Between after, or when evaporator coil temperature reaches preset temperature threshold value, judge that the icing on evaporator meets pre-conditioned.It is described Preset times can be that 2 times or 3 are inferior, and the Preset Time can be 10 minutes or 15 minutes etc., the preset temperature threshold value Can be -5 degree or -10 degree etc..Adding water, water pump 4 is opened, and after compressor opens refrigeration, detects that the water pump 4 that adds water has run several In the cycle, after preset times are reached, judge that the icing on evaporator 1 meets pre-conditioned;Or, being opened in the water pump 4 that adds water, compress After machine opens refrigeration, start timing, after refrigerating operaton Preset Time, judge that the icing on evaporator 1 meets pre-conditioned; Or, being opened in the water pump 4 that adds water, after compressor opens refrigeration, the coil temperature of evaporator 1 is detected, reached in the coil temperature of evaporator 1 During preset temperature threshold value, judge that the icing on evaporator 1 meets pre-conditioned.Icing on evaporator 1 meets pre-conditioned Afterwards, control compressor enters heating mode, and the ice-out that will be tied on evaporator 1 flows into drip tray 11, cleans evaporator 1. When compressor enters heating mode, the ice-out that will can be tied on evaporator 1 takes away the booty on evaporator 1, cleaning evaporation Device 1.
Step S40, flows into the water in drip tray tank and realizes wash cycles by delivery port;
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 Minute etc., the clean level of air-conditioner evaporator 1 is obtained by the time of wash cycles, when certain hour is reached, represent What evaporator 1 was washed in air-conditioner has cleaned up, and terminates cleaning process.In a preferred embodiment, in order to improve evaporator 1 Clean up degree, after wash cycles reach certain hour, close compressor, reduction adds water the rotating speed of water pump 4, and it is right to control The bottom of evaporator 1 is washed, and because of the rotating speed of water pump 4 reduction that adds water, the impulsive force to evaporator 1 can be reduced, that is to say, that water The bottom of evaporator 1 can be left to along evaporator, the time for resting on evaporator 1 can be more long, and cleaning performance can be better.The present embodiment The cleaning process of evaporator 1, melt cleaning when, drip tray 11 be connection air-conditioner outside, i.e. the water of cleaning is drained into air-conditioning Outside device, it is to avoid the filthy water wash cycles of cleaning pervaporation device 1 cause evaporator 1 to clean sordid problem.
The present embodiment is sprayed to evaporator 1 by by the water in water tank 2 by the water pump 4 that adds water, and opens compressor and first freezes Heat again, frozen by freezing, the booty and water on evaporator 1 are coagulated together, reheat and melt, by evaporator 1 Booty is taken away, and is discharged outside air-conditioner after first wash cycles, saves water resource, and the cleaning performance of evaporator 1 is ensured again, improves room Interior environment, and then air-conditioner comfort level is improved, by triple valve 14 between Jiang Shui squeezes into evaporator 1 and drains into air-conditioner outside Switching, saves parts, reduces cost.
In a preferred embodiment of the present invention, with reference to Fig. 4, the icing on an evaporator meet it is pre-conditioned after, control Compressor processed enters heating mode, and ice-out that will be tied on evaporator flows into drip tray, cleaning evaporator with by drip tray In water tank flowed into by delivery port realize between wash cycles, also including:
Step S60, improves the rotating speed of the water pump that adds water, and control filler pipe is rinsed against evaporator;
Step S70, after the ice tied on an evaporator melts completely, recovery add water water pump rotating speed to improve before turn Speed.
The ice condensed on thawing evaporator 1 is heated, so as to take away during the booty on evaporator 1, improves the water pump that adds water Rotating speed, i.e. increase water to the impulsive force of evaporator 1, and then can be with the significantly more efficient booty washed away on evaporator 1.Steaming After the ice tied melts completely on hair device 1, recovery adds water the rotating speed of the rotating speed to before improving of water pump.Ensureing that evaporator 1 is clear While washing effect, save resources, it is to avoid long-term rotating speed high runs the water pump 4 that adds water causes the situation of the wasting of resources.
