Then, on one side the action of above-mentioned the first embodiment also is described with reference to the flow chart shown in Fig. 4 on one side.

Under the state of user in the main body cover 15 that dust collecting part is installed on to main body of dust collector 12, if mains cord 44 is connected in the socket etc. of (insertion) wall, to control module 45, from commercial AC power e, provide (applying) power supply (voltage).

And control module 45 becomes the operation input wait state of setting button 38.That is, control module 45(is by operation judges section 51) judge whether to make electric dust collector 11 to start, in other words judged whether to operate the setting button 38(step 1) that electric blower 18 is started.

In this step 1, in the situation that being judged as, control module 45 do not make electric dust collector 11 start (the operating and setting button 38), repeating step 1, in the situation that be judged as, make electric dust collector 11 start (having operated setting button 38), the pattern (by electric power control part 52) that control module 45 utilization sets makes electric dust collector 11(electric blower 18) start (step 2), and (by sweeping efficiency calculating part 59) judges whether the front end (upstream extremity) in wind path W(extension tube 22) connecting floor cleaner brush 23(step 3).

In this step 3, connecting floor cleaner brush 23 in the situation that control module 45 is judged as, carry out as shown in Figure 5 the 1st control that (step 4), do not connect floor cleaner brush 23 in the situation that control module 45 is judged as, and carries out the 2nd shown in Fig. 6 and control (step 5).The dust together be drawn in wind path W with air by the driving of electric blower 18 flows into to dust collecting part through wind path organizator 13 and main body suction inlet 19, and is trapped by this dust collecting part.The air that traps dust is inhaled into electric blower 18, in the time of cooling this electric blower 18 from these electric blower 18 exhausts and to the outside exhaust of the main body cover 15 of main body of dust collector 12.

And, after step 4 and step 5, control module 45(is by operation judges section 51) judge whether to make electric dust collector 11(electric blower 18) stop, in other words having judged whether to operate the setting button 38(step 6) that electric blower 18 is stopped.And, in this step 6, in the situation that being judged as, control module 45 do not make electric dust collector 11 stop (the operating and setting button 38), return to step 3, in the situation that be judged as, make electric dust collector 11 stop (having operated setting button 38), control module 45(is by electric power control part 52) make electric blower 18 stop (step 7), end cleaning.In addition, although connection or the dismounting of judgement floor cleaner brush 23 when the startup of electric dust collector 11 in the present embodiment, but this judgement can be inserted in the timing arbitrarily in the 1st control and the 2nd is controlled, can switch the 1st control and the 2nd control according to connection or the dismounting of the floor cleaner brush 23 of judging at that time.

Then, on one side also control and describe with reference to the flow chart shown in Fig. 5 on one side for the above-mentioned the 1st.

Control module 45(is by display control unit 60) (step 11) then judges whether electric dust collector 11 suitably sucks and air is arranged, in other words judge whether electric blower 18 has brought into play effect (step 12) to remove the demonstration of display unit 20.

In this step 12, control module 45 is in the situation that be judged as that electric blower 18 does not play a role, air amount or sealed situation of wind path W etc. by foreign matter etc. such as obstruction due to dust collecting part etc. and not, return to step 12, brought into play effect in the situation that be judged as electric blower 18, control module 45(is by ground connection test section 67) judge floor cleaner brush 23 whether with swept surface ground connection (step 13).

In this step 13, in the situation that control module 45 be judged as floor cleaner brush 23 not with swept surface ground connection, return to step 13(or step 12), in the situation that be judged as floor cleaner brush 23 and swept surface ground connection, control module 45(is by offset detect section 68) judge floor cleaner brush 23 whether the speed more than the fixing speed to set in advance move (step 14).

And, in this step 14, be judged as floor cleaner brush 23 not in the situation that move with the speed more than the fixing speed of setting in advance at control module 45, return to step 13(or step 12), be judged as floor cleaner brush 23 with the speed more than the fixing speed of setting in advance in the situation that mobile, control module 45(is by amount of movement/time cumulation section 57) amount of movement and traveling time accumulative total (step 15) by floor cleaner brush 23 on swept surface.

Then, whether control module 45 judgements are more than the ormal weight of setting in advance (step 16) by the detected dust amount of optical sensor 53.In this step 16, in the situation that be judged as by the detected dust amount of optical sensor 53 more than the ormal weight for setting in advance, control module 45(adds up section 55 by dust amount) dust amount is added up to (step 17) and advances to step 18.And, in this step 16, in the situation that control module 45 is judged as by the detected dust amount of optical sensor 53, not more than the ormal weight of setting in advance, directly advance to step 18.

And, control module 45(is by adding up section 56 duration of runs) will the duration of runs of electric blower 18 accumulative total (step 18), and amount of movement and the traveling time of the floor cleaner brush 23 based on utilizing step 15 accumulative total on swept surface and utilize the cumulative amount of the dust amount of step 17 accumulative total to come to calculate sweeping efficiencies (step 19) by sweeping efficiency calculating part 59.Specifically, the cumulative amount of the dust amount that will be calculated by dust amount accumulative total section 55 is made as D, will be made as L by the amount of movement of floor cleaner brush 23 on swept surface that amount of movement/time cumulation section 57 calculates, when traveling time is made as to T1, utilizes sweeping efficiency H=D/(LT1) calculated.Afterwards, control module 45 judges in data store 69 whether stored mean value (step 20).In this step 20, in the situation that stored mean value in being judged as data store 69, control module 45 passes through also (by display control unit 60) control display unit 20 of sweeping efficiency calculating part 59 computational tasks efficiency indexs, thereby show as shown in Figure 7 sweeping efficiency and operating efficiency index (step 21), advance to step 6.Specifically, sweeping efficiency calculating part 59 will be stored in data store 69 before sweeping efficiency during cleaning repeatedly or certain in the past during cleaning the time the mean value of sweeping efficiency etc. while being made as A, utilize operating efficiency index K=H/A to be calculated.On the other hand, in step 20, in the situation that do not store mean value in being judged as data store 69, control module 45(is by display control unit 60) control display unit 20, thus only show sweeping efficiency (step 22), to step 6, advance.

Then, for the 2nd shown in above-mentioned steps 5, control, on one side also describe with reference to the flow chart shown in Fig. 6 on one side.

After the processing of the step 11 with control module 45 and the identical step 31 of step 12 and step 32, control module 45(adds up section 58 by respiratory time) respiratory time of actual dust is added up to (step 33).

Then, control module 45(is via handling part 54) judge whether by the detected dust amount of optical sensor 53 be more than the ormal weight of setting in advance (step 34).In this step 34, in the situation that be judged as by the detected dust amount of optical sensor 53 more than the ormal weight for setting in advance, control module 45(adds up section 55 by dust amount) by dust amount accumulative total (step 35), advance to step 36.And, in this step 34, in the situation that control module 45 is judged as by the detected dust amount of optical sensor 53, not more than the ormal weight of setting in advance, directly advance to step 36.

And, control module 45(is by adding up section 56 duration of runs) will the duration of runs of electric blower 18 accumulative total (step 36), the respiratory time based on utilizing step 33 accumulative total, utilize the dust amount of step 35 accumulative total cumulative amount, utilize calculate sweeping efficiencies (step 37) by sweeping efficiency calculating part 59 duration of runs of step 36 accumulative total.Specifically, sweeping efficiency calculating part 59 is made as D at the cumulative amount that will add up the dust amount that section 55 calculates by dust amount, will be made as by the duration of runs that adds up the electric blower 18 that section 56 calculates the duration of runs T2, in the time of will adding up respiratory time that section 58 calculates and be made as T3 by respiratory time, utilize sweeping efficiency H=D/(T2T3) calculated.Afterwards, control module 45, having carried out the step 38 identical to step 22 with above-mentioned steps 20 to the control of step 40, advances to step 6.

As described above, according to above-mentioned the first embodiment, sweeping efficiency calculating part 59 calculates sweeping efficiency except the cumulative amount of dust amount by the product of the amount of movement with floor cleaner brush 23 and traveling time, thereby the amount of movement of floor cleaner brush 23 or traveling time are fewer with respect to the cumulative amount of dust amount, the sweeping efficiency that calculated is larger.Therefore in general, when the purging zone to identical is cleaned, the cumulative amount of dust amount not there will be large change, can be using the above-mentioned sweeping efficiency calculated as the index that whether can effectively be cleaned purging zone.

And, sweeping efficiency calculating part 59 calculates sweeping efficiency except the cumulative amount of dust amount by the product of the duration of runs with electric blower 18 and actual respiratory time, thereby the respiratory time of the duration of runs of electric blower 18 or reality is fewer with respect to the cumulative amount of dust amount, the sweeping efficiency that calculated is larger, even the situation of therefore floor cleaner brush 23 removals being cleaned, also can be using the above-mentioned sweeping efficiency calculated as the index that whether can effectively be cleaned purging zone.

Then, with reference to Fig. 8 to Figure 10, the second embodiment is described.In addition, for the formation identical with above-mentioned the first embodiment and identical symbol is given in effect and the description thereof will be omitted.

This second embodiment is that electric dust collector 11 possesses detecting unit 71(Fig. 8 of the kind that can detect purging zone (sweeping area) in the above-described first embodiment) scheme.

This detecting unit 71 is used sensors, by being disposed at the kind that is read to detect purging zone such as the not shown detected parts of the ad-hoc location of each purging zone in room etc. through such as bar code or IC tag etc. the time.
