sidepiece air outlet

105 and 106 and top outlet inlet 110 discharge main bodys 2.Therefore, the cooling operation can be by carrying out with the air of heat exchanger 60 heat exchanges.

With reference to Figure 12, if air-conditioning energising (step S2), then controller determines whether to utilize cleaning filtration function key 810 or cleaning filtration execute key 830 to select cleaning filtration function (step S4).At this, controller represents to be arranged at the master controller in the main control box 800.

If select the cleaning filtration function, then utilize attached/separate detector 850 and determine that dust collecting unit 708 is whether attached or separate (step S6).At this, can utilize dust collecting unit display 880 show dust collecting units 850 attached/separate.For example, if the normal position is separated or be not attached to dust collecting unit 708, then dust collecting unit display 880 is used to show separating of dust collecting unit 708.

If dust collecting unit 708 is attached, then start the cleaning filtration function.At this, can utilize the startup of cleaning filtration function display 870 display filter cleaning functions.

When starting the cleaning filtration function, controller determines whether present mode is to execute pattern (step S8) by the cleaning filtration function automatic control mode of controlled filter device cleaning function key 810 or by the cleaning filtration of controlled filter device cleaning execute key 830.For example, if start the cleaning filtration function by controlled filter device cleaning execute key 830, then present mode is defined as cleaning filtration and executes pattern.

If present mode is defined as cleaning filtration and executes pattern, determine then whether air-conditioning is carrying out air conditioning operation (S10).

On the other hand, if utilize cleaning filtration function key 810 to start the cleaning filtration function, then present mode is defined as cleaning filtration function automatic control mode (step S22), and will compare (step S24) according to the accumulative total air conditioning time and the predetermined value of first timer 820.Consider accumulative total air conditioning time and cleaning air intake filter 203 time relatively set predetermined value.If the accumulative total air conditioning time does not reach the scheduled time, then stop the cleaning filtration function, no longer carry out.

On the other hand, if the accumulative total air conditioning time reaches the scheduled time, determine then whether air-conditioning is carrying out air conditioning operation (step S10).

In this way, determining whether to carry out the air conditioning operation, is in order to determine whether to carry out the cleaning filtration function.Therefore, can prevent that in the air conditioning operating process dust from dispersing and the mobile device external member 701 that is cleaned by

air inlet

201 and 301 inhaled airs stops.And, can prevent that the cleaning filtration function from being disturbed by the blowing power of air blast 70.

If air-conditioning is not being carried out air conditioning operation, then will be according to the accumulative total dwell time and predetermined value comparison (step S12) of the air blast 70 of second timer 840.At this, predetermined value can be after the power breakdown that is supplied to air blast 70 up to air blast 70 and stops the time to be spent fully.

If the accumulative total dwell time reaches predetermined value, then carry out cleaning filtration function (step S20).That is to say, drive cleaning filtration unit 700 according to following " cleaning filtration unit operations control method ".At this, can utilize the startup of cleaning filtration function display 870 display filter cleaning functions/stop.

Simultaneously, controller determines whether the cleaning filtration function finishes (step S16).At this, whether the cleaning filtration function is finished can be according to whether input filter cleaning instruction or determine in steps according to whether finishing institute according to the cleaning filtration control method of user, below this is described in more detail.

If finish the cleaning filtration function, then replacement is stored in the accumulative total air conditioning time (step S18) in first timer 820.Stop cleaning filtration function thereafter.

As mentioned above, if request stops to carry out the cleaning filtration function in carrying out the cleaning filtration function course, then stop the cleaning filtration function.

Operation according to cleaning filtration of the present invention unit 700 is below described.

If the cleaning filtration function is carried out in request, then supply power to and suck unit 705 and external member CD-ROM drive motor 754.Then, the impurity that adheres to air intake filter 203 by sucking unit 705 inhalation power and the CONTACT WITH FRICTION between agitator 760 and the air intake filter 203 be inhaled in the cleaner external member 701.

The impurity that is drawn in the cleaner external member 701 is transported in the dust separation unit 706 along dust flexible pipe 703 by pressure.

Be transported to impurity and air centrifugation in the dust separation unit 706, the impurity that is separated drops to the bottom of dust separation unit 706.Thereafter, impurity is collected in the dust collecting unit 708 by dust jockey 790.

Be transported to suction unit 705 from the isolated air of impurity by pressure by dust separation unit 706, and be discharged in the main body 2 from sucking unit 705.

As mentioned above, when carrying out the cleaning filtration function, cleaner external member 701 moves along air intake filter 203, and agitator 760 rotates.

That is to say,, then rotate travelling gear 759 to rotate external member wheel 752 if drive external member CD-ROM drive motor 754.As a result, cleaner external member 701 moves vertically.Here, cleaner external member 701 vertically moves in intimate contact by mobile guide member 770 and air intake filter 203.

With reference to Figure 13, if carry out cleaning filtration function (the step S14 of Figure 12), then cleaner external member 701 is moved according to following order.

When starting the cleaning filtration function, the reciprocating frequency n of cleaner external member 701 resets to 0 (step S100).Cleaner external member 701 the starting stage always under the situation that the extreme lower position of cleaner external member 701 is waited for, cleaner external member 701 moves up, and drives simultaneously and suck unit 705 (step S110).Therefore, since cleaner external member 701 move upward and by sucking the inhalation power of unit 705, the impurity that adheres to air intake filter 203 is inhaled into cleaning air intake filter 203.

In the process that moves upward of cleaner external member 701, utilize the run duration of the 3rd timer 866 accumulative total cleaner external members 701.The run duration of the cleaner external member 701 that the 3rd timer 866 is monitored and predetermined external member run duration be (step S130) relatively.Predetermined external member run duration is cleaner external member 701 moves to the mobile route of cleaner external member 701 from an end of the mobile route of cleaner external member 701 the normal time that the other end spent.

If the run duration of the cleaner external member 701 that the 3rd timer 866 is monitored, determines then whether cleaner external member 701 is positioned at extreme higher position (step S131) less than predetermined external member run duration.Whether be not positioned at the extreme higher position if external member position detection unit 860 detects cleaner external member 701, then cleaner external member 701 continues to move up.

Under the condition of run duration less than predetermined external member run duration of the cleaner external member 701 that the 3rd timer 866 is monitored, if external member position detection unit 860, especially first photoelectric sensor 862 detect the position of cleaner external member 701, if perhaps the run duration of cleaner external member 701 is more than the scheduled time, then cleaner external member 701 moves downward (step S140).

Because the inhalation power that moves downward and pass through to suck unit 705 of cleaner external member 701, the impurity that adheres to air intake filter 203 is inhaled into to clean air intake filter 203 once more.

Moving downward in the process of cleaner external member 701, utilize the run duration of the 3rd timer 866 accumulative total cleaner external members 701, and the run duration and predetermined external member run duration comparison (step S150) of the cleaner external member 701 that the 3rd timer 866 is monitored.

If the run duration of the cleaner external member 701 that the 3rd timer 866 is monitored, determines then whether cleaner external member 701 is positioned at extreme lower position (step S151) less than predetermined external member run duration.Utilize second photoelectric sensor 864 to detect cleaner external member 701 and whether be positioned at extreme lower position.If cleaner external member 701 is not positioned at extreme lower position, then cleaner external member 701 continues to move downward.

On the other hand, if cleaner external member 701 is positioned at extreme lower position, if perhaps the run duration of the 3rd timer 866 cleaner external member 701 of being monitored is more than the scheduled time, then the reciprocating frequency n accumulative total with cleaner external member 701 is n+1 (step S160).Then, will add up reciprocating frequency and predetermined external member reciprocating frequency relatively (step S180).At this, predetermined external member reciprocating frequency is set at and makes that air intake filter 203 is cleaned fully.

If the accumulative total reciprocating frequency of cleaner external member 701 reaches preset frequency, then cleaner external member 701 stops (step S190), and suction unit 705 stops stopping carrying out the cleaning filtration function.

If the motion process of cleaner external member 701 from a position to the next position, the run duration of the cleaner external member 701 that the 3rd timer 866 is monitored is more than predetermined external member run duration (step S130 or S150), then the testing result of first photoelectric sensor 862 and second photoelectric sensor 864 is left in the basket, and definite cleaner external member 701 is positioned at the next position.That is to say that the moving direction of cleaner external member 701 is changed.Based on the running status of the cleaner external member 701 of the detection of first photoelectric sensor 862 and 864 pairs of cleaner external members 701 of second photoelectric sensor by the submaster controllers control that is arranged in the cleaning filtration control cabinet 890.

If ask forcibly to stop the cleaning filtration function by controlled filter device cleaning execute key 830 in carrying out the cleaning filtration function course, then cleaner external member 701 stops immediately, and the cleaning filtration function is forced to stop.Alternatively, after cleaner external member 701 moved to initial position apace, just after the extreme lower position, the cleaning filtration function was forced to stop.

Figure 14 is according to the flow chart of method of cleaning filtration function that is used to control air-conditioning of embodiment when being shown in the cleaning filtration operating process the enforceable cleaning function halt instruction of input.

With reference to Figure 14, if cleaning filtration function (step S200) is carried out in request, then cleaner external member 701 moves back and forth (step S210).At this, the cleaning filtration function is carried out request and is comprised according to automatic control mode and two kinds of situations of compulsory execution pattern.The reciprocating motion of cleaner external member 701 is carried out in the mode identical with mode shown in Figure 13 with Figure 12.

In the reciprocating motion process of cleaner external member 701, master controller detects the cleaning filtration function stop request (step S220) of whether having imported in real time.

If imported the request of cleaning filtration function stop, determine then whether cleaner external member 701 is positioned at starting point (step S230).The information whether relevant cleaner external member 701 is positioned at starting point can be sent to master controller from the submaster controller of cleaning filtration control cabinet 890.

If cleaner external member 701 is positioned at starting point, then cleaner external member 701 stops (step S240) immediately.On the other hand, if cleaner external member 701 is not positioned at starting point, then cleaner external member 701 temporarily stops (step S231), moves to starting point (step S232) then.

Figure 15 is according to the flow chart of method of cleaning filtration function that is used to control air-conditioning of embodiment when being shown in cleaner external member fault.

With reference to Figure 15, if startup, determines then whether cleaner external member 701 is positioned at initial position (step S300) according to the cleaning filtration function of Figure 12 step S14.If cleaner external member 701 is not positioned at initial position, then cleaner external member 701 moves to initial position (step S301) to start next cleaning.

If start the cleaning filtration function, then cleaner external member 701 moves up or down (step S310) from initial position.Utilize external member position detection unit 860 detect cleaner external member 701 whether reach home, just peak or minimum point (step S320) thereafter.Thereafter, if cleaner external member 701 is positioned at terminal point, then the moving direction of cleaner external member 701 changes (step S330).Thereafter, controller determines whether cleaning filtration finishes (step S340).If cleaning filtration is not finished, then mobile cleaner external member 701 is with duplication filter cleaning function (step S310 is to step S340).

On the other hand, if cleaner external member 701 is not positioned at terminal point, then controller determines whether the cumulative movement time of cleaner external member 701 reaches the scheduled time (step S321).If the cumulative movement time of cleaner external member 701 reaches the scheduled time, then submaster controller changes signal with direction and is sent to cleaner external member 701 (step S322).At this, step S321 can carry out before step S320.That is to say that this method can be carried out according to the step S130 of Figure 13 and the order of step S131.Thereafter, if the cumulative movement time of cleaner external member 701 does not reach the scheduled time, then cleaner external member 701 continues to move.

After direction change signal was sent to cleaner external member 701, master controller or submaster controller determined whether the moving direction of cleaner external member 701 changes (step S323).For example, can whether change according to the direction of rotation of external member CD-ROM drive motor 754 or whether change, determine whether the moving direction of cleaner external member 701 changes according to the direction of rotation of external member wheel 752.For example, Hall element can be installed on external member CD-ROM drive motor 754 or the external member wheel 752 and change to detect direction of rotation.

Changed if master controller or submaster controller detect the moving direction of cleaner external member 701, then clean operation continue to be carried out, and determines that cleaner external member 701 normally moves.That is to say that if cleaning filtration is not finished (step S340), then this method is got back to step S310 to repeat control operation.

On the other hand, if the moving direction of cleaner external member 701 does not change, then master controller or submaster controller stop cleaner external member 701 (step S324).Stop cleaner external member 701 after immediately stop cleaning filtration function thereafter.Alternatively, before stopping the cleaning filtration function, display 600 can be used for producing the alarm signal (step S325) of 701 inefficacies of report cleaner external member or fault.The example of alarm signal comprises chimes of doom, alarm sound and ON/OFF lamp.
