Description
Technical field
The utility model belongs to the air-conditioner technical field, is specifically related to a kind of air-conditioner.
Background technology
Existing family expenses and commercial split-type air conditioner device all comprise the control system, just change control circuit, outdoor radiator and heat radiation motor, and the control system connects the heat radiation motor through just changeing control circuit, and heat radiation motor and aerofoil fan are in transmission connection and rotate to drive aerofoil fan.During the air-conditioner electrifying startup, control system command heat radiation motor forward rotation sucks air thereby drive aerofoil fan, and outdoor heat exchanger is carried out forced-convection heat transfer, to improve the coefficient of heat transfer, increases exchange capability of heat.After the long-term use of air-conditioner; Be exposed to outdoor heat exchanger owing to existing inevitable dust to cause heat exchanger windward side dust stratification in the air; Heat exchanger heat exchange resistance is increased, thereby even block the air channel and the Performance And Reliability of air-conditioning system is caused have a strong impact on.In order to address this problem, existing method mainly is to clean through manual work timing heat exchanging device, and dust stratification is cleaned out.Obviously, not only workload is big for the method for cleaning through manual work, and particularly very inconvenient in the exterior wall operation of skyscraper in the exterior wall operation, also can cause great danger to personnel, moreover this method can not tackle the problem at its root.
The utility model content
The utility model technical problem to be solved provides a kind of air-conditioner of dedusting automatically.
The utility model solves the technical scheme that its technical problem adopted: air-conditioner, comprise the difference connection control system and the just commentaries on classics control circuit of the motor that dispels the heat, and also comprise reverse turn control circuit, reverse turn control circuit is the connection control system and the motor that dispels the heat respectively.
The beneficial effect of the utility model is: the utility model has only on the basis of just changeing control circuit at former air-conditioner increases a reverse turn control circuit; Automatic control through the control system; Can when air-conditioner is started shooting, start heat radiation motor inverted command earlier, make heat radiation motor antiport, change the flow direction of air in the air channel through reverse turn control circuit; The dust stratification of the windward side during with heat exchanging device operate as normal oppositely purges removing, realizes automatic dedusting; When dispelling the heat the motor antiport after a period of time, the control system is just changeing order through just changeing control circuit startup heat radiation motor again, and this moment, air-conditioning ran well.In addition, also can take the dust stratification of aforesaid way heat exchanging device windward side oppositely to purge removing during the air-conditioning shutdown, and then normal shutdown.The utility model air-conditioner increases a reverse turn control circuit; Need not change former outdoor heat exchanger air channel structure, also can not influence the normal heat exchange of heat exchanger, through when starting shooting and/or shut down, starting heat radiation motor inverted command, the dust stratification of heat exchanging device windward side oppositely purges; In time, effectively remove dust stratification; Guarantee the air-conditioner long-term stable operation, reduce the workload of air-condition heat exchanger manual maintenance, practice thrift operating cost.

Fig. 2 is the utility model air-conditioner heat exchange motor steering control block diagram;
Fig. 3 is heat exchanger and heat exchange motor position sketch map;
Be labeled as among the figure: control system 1, just change control circuit 2, heat radiation motor 3, aerofoil fan 4, reverse turn control circuit 5, heat exchanger 6, heat exchanger windward side 6-1, exhaust outlet 7.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in accompanying drawing 1 and 3; Existing family expenses and commercial split-type air conditioner device all comprise control system 1, just change control circuit 2, outdoor radiator 6 and heat radiation motor 3; Control system 1 connects heat radiation motor 3 through just changeing control circuit 2, and heat radiation motor 3 is in transmission connection with aerofoil fan 4 and rotates to drive aerofoil fan 4.As shown in Figure 1, during the air-conditioner electrifying startup, control system 1 instruction heat radiation motor, 3 forward rotation suck air thereby drive aerofoil fan 4 by heat exchanger windward side 6-1, discharged by exhaust outlet 7, thereby outdoor heat exchanger 6 is carried out forced heat-exchanging.Air-conditioner is long-term use after, be exposed to outdoor heat exchanger windward side 6-1 dust stratification owing to existing inevitable dust to cause in the air, heat exchanger 6 heat exchange resistances are increased, thereby even the obstruction air channel Performance And Reliability of air-conditioning system caused have a strong impact on.
As shown in Figure 2, the utility model air-conditioner not only comprises the respectively just commentaries on classics control circuit 2 of connection control system 1 and heat radiation motor 3, also comprises reverse turn control circuit 5, and reverse turn control circuit 5 is connection control system 1 and heat radiation motor 3 respectively.
As shown in Figure 1; The heat radiation motor 3 of architomia air-conditioner can only rotate to a direction with aerofoil fan 4; Therefore the flow direction of air can only suck air by heat exchanger windward side 6-1 in the air-conditioner operation process; Discharge by exhaust outlet 7 again, therefore, will be when air-conditioner uses for a long time at 6-1 place, heat exchanger windward side dust stratification.The utility model has only on the basis of just changeing control circuit 2 at former air-conditioner increases a reverse turn control circuit 5; Through the automatic control of control system 1, can, air-conditioner start heat radiation motor 3 inverted command earlier when starting shooting through reverse turn control circuit 5, make heat radiation motor 3 antiports; Reverse turn control circuit 5 as shown in Figure 2 is in the state of unlatching; Be in closing state and just changeing control circuit 2, thereby change the flow direction of air in the air channel, be i.e. in the opposite direction during air-flow direction and air-conditioning normal operation; The dust stratification of windward side 6-1 during with heat exchanging device 6 operate as normal oppositely purges removing, realizes automatic dedusting; When dispelling the heat motor 3 antiports after a period of time, control system 1 is just changeing order through just changeing control circuit 2 startup heat radiation motors 3 again, and this moment, air-conditioning ran well.Through experiment confirm, described antiport a period of time, optimum length is at five to 60 seconds, and the heat radiation motor 3 each antiports in the air-conditioner can be removed dust stratification clean in five to 60 seconds.In addition, the air-conditioning shutdown time also can take the dust stratification of aforesaid way heat exchanging device windward side 6-1 oppositely to purge removing, and process is identical during with start, normal shutdown again after the dedusting end.It will be understood by those skilled in the art that; The utility model starts heat radiation motor 3 inverted command and oppositely purges dedusting in the time of might not being limited in start and/or shutdown; When being necessary, also can be implemented in the reverse purging of realization in the operation of air conditioner through the control command that changes control system 1.The utility model air-conditioner increases a reverse turn control circuit 5; Need not change former outdoor heat exchanger 6 and air channel structure, also can not influence heat exchanger 6 normal heat exchange, through when starting shooting and/or shut down, starting heat radiation motor 3 inverted command, the dust stratification of heat exchanging device windward side 6-1 oppositely purges; In time, effectively remove dust stratification; Guarantee the air-conditioner long-term stable operation, reduce the workload of air-condition heat exchanger 6 manual maintenance, practice thrift operating cost.
