Furthermore, the display control unit 60 controls the display unit 20 so as to display the cleaning efficiency and work efficiency index calculated by the cleaning efficiency calculation unit 59 .

Next, the operation of the first embodiment described above will be described with reference to the flowchart shown in FIG. 4 .

When the user connects (inserts) the power supply cord 44 to (inserts) the power supply cord 44 in the state that the dust collecting unit is installed in the main body case 15 of the cleaner main body 12, the control unit 45 is supplied with ( Applied) power (voltage).

Furthermore, the control unit 45 enters a waiting state for an operation input of the setting button 38 . That is, the control unit 45 judges (via the operation judging unit 51 ) whether or not the electric vacuum cleaner 11 is activated, in other words, whether the setting button 38 for activating the electric blower 18 is operated (step 1 ).

In this step 1, when the control unit 45 determines that the electric vacuum cleaner 11 is not to be activated (the setting button 38 is not operated), step 1 is repeated, and when it is determined that the electric vacuum cleaner 11 is to be activated (the setting button 38 is operated) In the case of , the control unit 45 starts the electric vacuum cleaner 11 (electric blower 18 ) using the set operation mode (through the power control unit 52 ) (step 2), and judges (through the cleaning efficiency calculation unit 59 ) whether the W (the front end (upstream end) of the extension pipe 22) is connected to the floor brush 23 (step 3).

In this step 3, when the control unit 45 determines that the floor brush 23 is connected, the first control (step 4) shown in FIG. 5 is performed, and when the control unit 45 determines that the floor brush 23 is not connected , the second control shown in FIG. 6 is performed (step 5). The dust sucked into the air passage W together with the air by the driving of the electric blower 18 flows into the dust collecting part through the air passage forming body 13 and the main body suction port 19, and is collected by the dust collecting part. The dust-collected air is sucked into the electric blower 18 and exhausted from the electric blower 18 to the outside of the main body casing 15 of the cleaner body 12 while cooling the electric blower 18 .

And after step 4 and step 5, the control unit 45 (through the operation judging part 51) judges whether to make the electric vacuum cleaner 11 (electric blower 18) stop, in other words judges whether to operate the setting button 38 that makes the electric blower 18 stop (step 6 ). And in this step 6, when the control unit 45 determines that the electric vacuum cleaner 11 has not been stopped (the setting button 38 has not been operated), it returns to step 3, and when it is determined that the electric vacuum cleaner 11 is stopped (the setting button is operated) 38), the control unit 45 (via the power control unit 52) stops the electric blower 18 (step 7), and ends the cleaning. In addition, in the present embodiment, although the connection or detachment of the floor brush 23 is judged when the electric vacuum cleaner 11 is started, this judgment can be inserted at any timing in the first control and the second control, and it can be determined based on the timing determined at that time. The connection or detachment of the floor brush 23 switches between the first control and the second control.

Next, the first control described above will be described with reference to the flowchart shown in FIG. 5 .

The control unit 45 (via the display control unit 60) clears the display of the display unit 20 (step 11), and then determines whether the electric vacuum cleaner 11 is properly sucking in air, in other words, whether the electric blower 18 is functioning (step 12).

In this step 12, when the control unit 45 judges that the electric blower 18 is not functioning, for example, the air is not sucked in due to clogging of the dust collecting part, or the air passage W is blocked by a foreign object, etc., it returns to the step 12. , when it is determined that the electric blower 18 is functioning, the control unit 45 (via the ground contact detection unit 67 ) determines whether the floor brush 23 is in contact with the surface to be cleaned (step 13 ).

In this step 13, when the control unit 45 determines that the floor brush 23 is not in contact with the surface to be cleaned, it returns to step 13 (or step 12), and when it is determined that the floor brush 23 is in contact with the surface to be cleaned, the control unit 45 The unit 45 (via the movement amount detection unit 68 ) determines whether or not the floor brush 23 is moving at a speed equal to or higher than a predetermined speed set in advance (step 14 ).

And in this step 14, when the control unit 45 judges that the floor brush 23 is not moving at a speed higher than the predetermined speed set in advance, it returns to step 13 (or step 12), and when it is judged that the floor brush 23 is moving When moving at a speed equal to or higher than the predetermined speed set in advance, the control unit 45 (via the movement amount/time integration unit 57 ) accumulates the movement amount and movement time of the floor brush 23 on the surface to be cleaned (step 15 ).

Next, the control unit 45 determines whether or not the amount of dust detected by the optical sensor 53 is equal to or greater than a predetermined amount set in advance (step 16 ). In this step 16, when it is determined that the amount of dust detected by the optical sensor 53 is greater than or equal to a predetermined amount set in advance, the control unit 45 (through the dust amount integrating unit 55) accumulates the amount of dust (step 17) and Proceed to step 18. Then, in this step 16 , when the control unit 45 determines that the amount of dust detected by the optical sensor 53 is not equal to or greater than a predetermined amount set in advance, the process proceeds directly to step 18 .

Moreover, the control unit 45 (through the operation time accumulation unit 56) accumulates the operation time of the electric blower 18 (step 18), and based on the movement amount and movement time of the floor brush 23 accumulated in step 15 on the surface to be cleaned and the use step The cleaning efficiency is calculated by the cleaning efficiency calculation unit 59 based on the cumulative amount of accumulated dust (step 19). Specifically, the accumulated amount of the dust amount calculated by the dust amount integrating unit 55 is set as D, the moving amount of the floor brush 23 calculated by the moving amount/time integrating portion 57 on the surface to be cleaned is set as L, and the moving amount When the time is T1, the calculation is performed using the cleaning efficiency H=D/(L·T1). After that, the control unit 45 judges whether or not the average value is stored in the data storage unit 69 (step 20 ). In this step 20, when it is determined that the average value is stored in the data storage unit 69, the control unit 45 calculates the work efficiency index through the cleaning efficiency calculation unit 59 and controls the display unit 20 (through the display control unit 60) so that As shown in FIG. 7 , display the cleaning efficiency and work efficiency index (step 21 ), and proceed to step 6 . Specifically, the cleaning efficiency calculation unit 59 uses the work efficiency index when A is the average value of cleaning efficiencies during previous cleanings stored in the data storage unit 69 or cleaning efficiencies during cleanings over a certain period of time in the past, and the like. K=H/A is used for calculation. On the other hand, in step 20, when it is determined that the average value is not stored in the data storage unit 69, the control unit 45 (via the display control unit 60) controls the display unit 20 to display only the cleaning efficiency (step 22), Proceed to step 6.

Next, the second control shown in step 5 above will be described with reference to the flowchart shown in FIG. 6 .

After the processing of Step 31 and Step 32 which are the same as Step 11 and Step 12 of the control unit 45 , the control unit 45 (via the suction time integration unit 58 ) integrates the actual dust suction time (Step 33 ).

Next, the control unit 45 determines (via the processing unit 54 ) whether or not the amount of dust detected by the optical sensor 53 is equal to or greater than a predetermined amount set in advance (step 34 ). In this step 34, when it is determined that the amount of dust detected by the optical sensor 53 is greater than or equal to a predetermined amount set in advance, the control unit 45 (via the dust amount integrating unit 55) accumulates the amount of dust (step 35), Proceed to step 36. Then, in this step 34 , when the control unit 45 determines that the amount of dust detected by the optical sensor 53 is not more than a predetermined amount set in advance, the process proceeds directly to step 36 .

Furthermore, the control unit 45 (via the operating time accumulating unit 56 ) accumulates the operating time of the electric blower 18 (step 36 ), based on the suction time accumulated in step 33 , the accumulated amount of dust accumulated in step 35 , and the cumulative amount of dust accumulated in step 36 . The cleaning efficiency is calculated by the cleaning efficiency calculation unit 59 (step 37 ). Specifically, the cleaning efficiency calculating unit 59 sets the accumulated amount of dust calculated by the dust amount integrating unit 55 as D, the operating time of the electric blower 18 calculated by the operating time integrating unit 56 as T2, and When the suction time calculated by the suction time integration unit 58 is T3, the calculation is performed using cleaning efficiency H=D/(T2·T3). Thereafter, the control unit 45 proceeds to step 6 after performing the control of steps 38 to 40 that are the same as steps 20 to 22 described above.

As mentioned above, according to the above-mentioned first embodiment, the cleaning efficiency calculating part 59 calculates the cleaning efficiency by calculating the cumulative amount of dust removal by the product of the moving amount of the floor brush 23 and the moving time, so that the moving amount or movement of the floor brush 23 The smaller the cumulative amount of time relative to the amount of dust, the greater the calculated cleaning efficiency. Generally, when the same cleaning area is cleaned, the cumulative amount of dust does not fluctuate greatly, so the cleaning efficiency calculated above can be used as an index of whether the cleaning area can be effectively cleaned.

And, the cleaning efficiency calculation part 59 calculates the cleaning efficiency by calculating the cumulative amount of the dust removal amount by the product of the operation time of the electric blower 18 and the actual suction time, so that the operation time of the electric blower 18 or the actual suction time is relative to the dust amount. The smaller the cumulative amount of , the greater the calculated cleaning efficiency. Therefore, even if the floor brush 23 is removed for cleaning, the above-mentioned calculated cleaning efficiency can be used as an indicator of whether the cleaning area can be effectively cleaned. index of.

Next, a second embodiment will be described with reference to FIGS. 8 to 10 . In addition, the same code|symbol is attached|subjected to the same structure and function as said 1st Embodiment, and the description is abbreviate|omitted.

This second embodiment is a configuration in which electric vacuum cleaner 11 includes detection means 71 ( FIG. 8 ) capable of detecting the type of cleaning area (cleaning area) in the above-mentioned first embodiment.

The detection unit 71 detects the type of the cleaning area by using a sensor or the like to read when an unshown detection member disposed at a specific position of each cleaning area such as a room passes by, for example, a barcode or an IC tag.

Further, this detection unit 71 is electrically connected to a cleaning area determination unit 72 as a determination unit of the control unit 45 . The cleaning area determination unit 72 is electrically connected to the cleaning efficiency calculation unit 59 , determines the type of cleaning area detected by the detection unit 71 , and can output the determination result to the cleaning efficiency calculation unit 59 .

And, like the flow chart shown in Figure 9, between step 2 and step 3, the control unit 45 detects the type of the cleaning area through the detection unit 71, and (through the cleaning area judging part 72) judges its type (step 45 ). As a result, in each of the first control and the second control, the cleaning efficiency or work efficiency index is displayed for each type of cleaning area. For example, in FIG. 10 , the cleaning efficiency and work efficiency indexes of each cleaning area are arranged vertically and displayed.

In this way, according to the second embodiment, the cleaning efficiency or work efficiency index is calculated by the cleaning efficiency calculation unit 59 for each type of cleaning area detected by the detection unit 71, and the calculated cleaning efficiency or work efficiency index is used.

It can be connected to a predetermined charging stand (not shown) at a predetermined position or the like, and charging can be performed.

Next, the operation of the fourth embodiment described above will be described with reference to the flowchart shown in FIG. 16 .

When the power switch (not shown) is turned on by the user, or when the power switch is turned on at a predetermined time, etc., when the electric vacuum cleaner 11 is in the activated state, the control unit 45 The electric blower 18 is activated (by the power control unit 52 ) in accordance with the set cleaning mode (step 51 ), while (by the traveling processing unit 99 ), information such as the distance to the obstacle detected by the sensor 86 is processed, While driving the motors 84, 84 (via the travel control unit 98), the driving wheels 83, 83 are driven, and the electric vacuum cleaner 11 (vacuum cleaner main body 77) is autonomously moved (autonomously travels) in accordance with the set cleaning mode (step 52).

Next, the control unit 45 (via the display control unit 60) clears the display of the display unit 20 (step 53), and judges whether the electric vacuum cleaner 11 has properly inhaled air, in other words, judges whether the electric blower 18 is functioning (step 54).

In this step 54, when the control unit 45 judges that the electric blower 18 is not functioning, that air is not sucked in due to clogging of the dust collecting part 82, etc., or that the suction port 91 is blocked by a foreign object, etc., the return is returned. Step 54, when it is determined that the electric blower 18 is functioning, the control unit 45 (via the movement amount detection unit 68) determines whether the electric vacuum cleaner 11 (vacuum cleaner main body 77) is moving at a speed greater than or equal to a predetermined speed set in advance ( Step 55). In addition, the dust sucked together with the air from the suction port 91 by the driving of the electric blower 18 is collected by the dust collecting part 82 . The dust-collected air is sucked into the electric blower 18 , is exhausted from the electric blower 18 while cooling the electric blower 18 , and is exhausted to the outside of the main body casing 81 of the cleaner main body 77 .

In addition, in step 55, when the control unit 45 determines that the electric vacuum cleaner 11 (vacuum cleaner main body 77) is not moving at a speed greater than or equal to a predetermined speed set in advance, the process returns to step 55 (or step 54). When the electric vacuum cleaner 11 (vacuum cleaner main body 77 ) moves at a speed higher than a predetermined speed set in advance, the control unit 45 (via the movement amount/time accumulating unit 57 ) controls the electric vacuum cleaner 11 (vacuum cleaner main body 77 ) on the surface to be cleaned. The above moving amount and moving time are accumulated (step 56).

Next, the control unit 45 determines whether or not the amount of dust detected by the optical sensor 53 is equal to or greater than a predetermined amount set in advance (step 57 ). In this step 57, when it is determined that the amount of dust detected by the optical sensor 53 is greater than or equal to a predetermined amount set in advance, the control unit 45 (via the dust amount integrating unit 55) accumulates the amount of dust (step 58) , (by the operation time integration unit 56 ) the operation time of the electric blower 18 is accumulated (step 59 ). Then, in this step 57 , when the control unit 45 determines that the amount of dust detected by the optical sensor 53 is not equal to or greater than a predetermined amount set in advance, the process proceeds directly to step 59 .

And the control unit 45 judges whether to continue driving the electric vacuum cleaner 11 (electric blower 18 ) (step 60 ), and returns to step 54 when it judges to make it run. And, when it is determined in step 60 that the operation is terminated, the electric blower 18 is stopped, the electric vacuum cleaner 11 (vacuum cleaner body 77 ) is moved to the charging stand, and the cleaning is completed with the charging terminals 101 and 101 connected to the charging stand. (step 61). Next, the control unit 45 uses the cleaning efficiency calculation unit 59 based on the movement amount and movement time of the electric vacuum cleaner 11 (vacuum cleaner body 77 ) accumulated on the surface to be cleaned in step 56 and the accumulated amount of dust accumulated in step 58 . Calculate cleaning efficiency (step 62). The calculation method of the cleaning efficiency in this step 62 is the same as that in the above-mentioned step 19, so it is omitted. Thereafter, the control unit 45 judges whether or not the average value is stored in the data storage unit 69 (step 63 ). In this step 63, when it is determined that the average value is stored in the data storage unit 69, the control unit 45 calculates the work efficiency index through the cleaning efficiency calculation unit 59, and controls the display unit 20 (through the display control unit 60) so that Display cleaning efficiency and operating efficiency indicators (step 64). The calculation method of the work efficiency index in this step 64 is the same as that of the above-mentioned step 21, so it is omitted. On the other hand, in step 63, when it is determined that the average value is not stored in the data storage unit 69, the control unit 45 (via the display control unit 60) controls the display unit 20 to display only the cleaning efficiency (step 65) .

In this way, according to the fourth embodiment, the cleaning efficiency calculation unit 59 calculates the cleaning efficiency by calculating the cumulative amount of dust removed by the product of the moving amount of the cleaner body 77 and the moving time, so that the moving amount or the moving time of the cleaner body 77 is relative to The smaller the cumulative amount of dust, the greater the calculated cleaning efficiency. Generally, when the same cleaning area is cleaned, the cumulative amount of dust does not fluctuate greatly, so the cleaning efficiency calculated above can be used as an index of whether the cleaning area is efficiently cleaned.

Furthermore, since the degree of cleaning achievement can be expressed by the above-mentioned cleaning efficiency and work efficiency indexes, it is possible for the user to promote improvement in cleaning efficiency by changing the setting of the cleaning mode, etc., and can contribute to energy saving. That is, for example, when the cleaning efficiency in the fine cleaning mode is relatively low, or when the cleaning efficiency in the normal cleaning mode is relatively low, it can be determined that there is waste in the autonomous movement distance of the cleaner main body 77, so by setting, for example, By changing the setting of the cleaning mode such as the normal cleaning mode or the partial cleaning mode, the cleaning efficiency can be improved and an appropriate cleaning mode can be selected.

In addition, in the above-mentioned fourth embodiment, the cleaning mode is not only selected from the modes stored in advance, but also can be arbitrarily set by the user, for example. Furthermore, the setting of the cleaning mode may include not only the setting of the movement (travel) mode of the cleaner main body 77 but also the setting of the input (operation mode) of the electric blower 18 , and the like.

Furthermore, like the second and third embodiments described above, the type of cleaning area (cleaning area) is automatically detected or manually input by the user, and the cleaning efficiency calculation unit 59 separates the cleaning area for each type of cleaning area. to calculate the cleaning efficiency or operating efficiency index, and the calculated cleaning efficiency or operating efficiency index can be displayed on the display unit 20 . Also in this case, the same operation and effect as those of the above-mentioned second and third embodiments can be exhibited.

Furthermore, the structure in which electric vacuum cleaner 11 (vacuum cleaner body 77 ) autonomously moves (autonomously travels) includes not only a structure in which the sensor 86 detects an obstacle or the like while moving (traveling), but also a configuration in which the electric vacuum cleaner 11 (vacuum cleaner body 77) moves along a preset movement ( Marching) mode to automatically move (traveling) composition (self-progressing composition), etc.

In addition, the electric vacuum cleaner 11 (vacuum cleaner main body 77 ) that moves autonomously (self-propelled) may be manually operated using a remote controller or the like.

Moreover, according to at least one embodiment described above, based on the cumulative amount of dust detected by the optical sensor 53, the movement amount of the floor brush 23 or the cleaner body 77 on the surface to be cleaned, and the movement of the floor brush 23 or the cleaner body 77 The moving time on the surface to be cleaned is calculated by the cleaning efficiency calculation unit 59, and the calculated cleaning efficiency is displayed by the display unit 20, so that the cleaning efficiency can be effectively notified to the user by the cleaning efficiency .

Furthermore, when the cleaning efficiency calculation unit 59 has an average value of the cleaning efficiencies of previous multiple cleanings stored in the data storage unit 69 or the cleaning efficiencies of the past certain period of cleaning, etc., it uses the average value to divide According to the cleaning efficiency, the operation efficiency index is calculated, and the calculated operation efficiency index is displayed through the display unit 20, so that the user can realize whether the cleaning efficiency is improved compared with the past cleaning, and the cleaning achievement can be more effectively calculated. inform the user.

In addition, in each of the above-mentioned embodiments, the display unit 20 displays the cleaning efficiency and the work efficiency index respectively during cleaning in real time, but it may be configured to display the index when the electric blower 18 (electric vacuum cleaner 11 ) is stopped at the end of cleaning. show.
