Embodiment 1
In FIG. 1, 1 is a vacuum cleaner according to Embodiment 1 of the present invention. This vacuum cleaner 1 has a suction port for air (dust-containing air) containing dust and dust on the floor surface, and a suction port having a rotating brush (not shown) that scrubs up dust on the floor surface. A body 2 is provided. One end of a hollow cylindrical suction pipe 3 is connected to the suction port body 2. The other end of the suction pipe 3 is provided with a hand operating part 4 having a grip part 4c on which an operation switch part 4a for changing the operating state of the vacuum cleaner 1 is arranged. In addition, one end (front end) of a flexible bellows-like hose 5 is connected to the other end of the hand operation unit 4 via the hand operation unit 4 bent in the middle.

  The vacuum cleaner main body 6 is connected to the other end (rear end) of the hose 5. 2 to 4 show the appearance of the cleaner body 6. FIG. The other end of the hose 5 is connected to a hose connection portion 7 provided at the front end portion of the cleaner body 6. The vacuum cleaner main body 6 is provided with a suction air passage 11 communicated with the hose connection portion 7.

  The vacuum cleaner main body 6 accommodates an electric blower 9 that generates suction air, a control circuit board, a cord reel of a power cord, and the like. Wheels 10 are attached to both sides of the rear portion of the cleaner body 6. The vacuum cleaner body 6 is energized when the power cord is connected to an external power source, and the electric blower 9 is driven to perform a suction operation. The suction port body 2, the suction pipe 3, the hand operating section 4, the hose 5, and the suction air path 11 constitute a part of a suction path for allowing dust-containing air to flow from the outside to the inside of the cleaner body 6. .

  The dust collection unit 8 is mounted and accommodated in a dust collection unit storage portion 6 a formed on the upper side of the cleaner body 6. At this time, the dust collection unit 8 extends from the cleaner main body 6 and is predetermined in a state where almost half of the lower side of the dust collection unit 8 is covered by the housing member 12 disposed on the outer periphery of the dust collection unit 8. Is housed in a position. The cleaner body 6 in a state where the dust collection unit 8 is accommodated in the dust collection unit accommodation portion 6a will be described with reference to FIG. The dust collection unit 8 includes a dust collection container 13 including a substantially cylindrical swivel part 13a and a dust collection part 13b. Further, the dust collection unit 8 is provided with an inlet (not shown) for taking dust-containing air into the dust collection container 13 through the suction air passage 11. The swivel part 13a of the dust collecting container 13 swirls the dust-containing air that has flowed from the inflow port to separate the air and dust (dust). And the dust collection part 13b captures the dust (dust) separated from the dust-containing air by the swivel part 13a.

  Inside the dust collecting container 13, a substantially cylindrical discharge pipe 15 is disposed substantially concentrically with respect to the substantially cylindrical shape of the dust collecting container 13. The discharge pipe 15 includes a mesh member 15a on a part of its side wall, and the mesh member 15a constitutes a communication portion 16 that communicates the dust collecting container 13 and the discharge pipe 15. Further, the dust collection unit 8 has a filter 17 that collects fine dust that cannot be removed by the swivel unit 13a and the like, and a discharge port 18 that discharges air from which dust is separated from the dust-containing air by the swivel unit 13a and the like. Is provided.

  Furthermore, a gap is formed in the dust collecting container 13 from the side wall or bottom wall of the discharge pipe 15 toward the inner wall of the dust collecting container 13 and between the dust collecting container 13 and the inner wall. A partition wall 19a arranged in a state is provided. Then, the revolving part 13a and the dust collecting part 13b of the dust collecting container 13 are partitioned by the partition wall 19a. Further, the partition wall 19a suppresses air from flowing from the swivel unit 13a to the dust collection unit 13b, and prevents dust accumulated in the dust collection unit 13b from being re-scattered into the swivel unit 13a.

  An outlet (not shown) is provided at the rear end of the suction air passage 11, and when the dust collection unit 8 is mounted and accommodated in the dust collection unit accommodation portion 6 a of the cleaner body 6, The outlet of the suction air passage 11 and the inlet of the dust collection unit 8 are joined, and the suction air passage 11 and the swivel part 13a of the dust collection container 13 are communicated. Further, an exhaust air passage 20 is provided on the upper rear side of the cleaner body 6. In a state where the dust collection unit 8 is accommodated in the dust collection unit accommodation portion 6 a, the discharge port 18 of the dust collection unit 8 is connected to the exhaust air passage 20.

  In front of the exhaust air passage 20 inside the cleaner body 6, an electric blower housing portion 6 b in which the electric blower 9 is housed is disposed. The electric blower 9 drives suction of dust-containing air dust into the dust collecting container 13 of the dust collecting unit 8. That is, when the electric blower 9 operates, the air pressure in the electric blower housing portion 6b in which the electric blower 9 is housed decreases. This decrease in the atmospheric pressure propagates from the electric blower housing 6 b to the exhaust air passage 20, the discharge port 18, the dust collecting container 13, and the suction air passage 11. And the fall of this atmospheric pressure finally reaches the suction port body 2 and becomes the air suction force in the suction port body 2.

Thus, the dust-containing air containing the dust sucked together with the air through the suction port body 2 by the suction force driven by the electric blower 9 passes through the suction pipe 3, the hand operating section 4 and the hose 5 to be cleaned. Reach body 6. The dust-containing air that has reached the cleaner body 6 passes through the suction air passage 11 of the cleaner body 6 and flows into the swivel part 13 a of the dust collection container 13 from the inlet of the dust collection unit 8. This dust-containing air flows in a substantially tangential direction with respect to the side wall of the swivel portion 13a and becomes a swirling airflow. Then, while forming a forced vortex region in the vicinity of the central axis and a quasi-free vortex region on the outer periphery thereof, it flows downward due to its path structure and gravity. At this time, since centrifugal force acts on dust (dust) in the air, it is pressed against the inner wall of the swivel unit 13a and separated from the air.

  The dust separated from the dust-containing air rides on the descending swirling airflow, travels below the swiveling portion 13a, and is collected by the dust collecting portion 13b. At this time, the partition wall 19a prevents the flow of air (air) from the swivel unit 13a to the dust collection unit 13b, and the re-scattering of dust accumulated in the dust collection unit 13b is suppressed. The air from which the dust (dust) has been removed flows into the discharge pipe 15 from the swivel part 13 a through the communication part 16. The air that has flowed into the discharge pipe 15 is discharged from the discharge port 18 to the exhaust air passage 20 after the fine dust that could not be separated by the swivel unit 13 a is removed by the filter 17. After that, the air is discharged to the outside of the cleaner body 6 through an exhaust air path 20 and an exhaust path including an exhaust port (not shown).

  The operation switch unit 4a of the hand operation unit 4 instructs to start and stop driving the electric blower 27 and to control the output (for example, “strong”, “medium”, and “weak”).

Next, a method for calculating the accumulated moving distance information and the reciprocating speed information will be described.
The accumulated moving distance information and the reciprocating speed information are the accelerations in the front-rear direction detected by the acceleration sensor 4b when the user of the vacuum cleaner 1 grips the grip part 4c and reciprocates the hand operating part 4 in the front-rear direction, for example. It calculates using the information of the sine change of. When the hand operation unit 4 reciprocates, the suction port body 2 connected to the hand operation unit 4 via the suction pipe 3 also reciprocates. Here, it is assumed that the reciprocating movement of the suction port body 2 is the same as the reciprocating movement of the hand operating unit 4.

  FIG. 9A shows the longitudinal acceleration detected by the acceleration sensor 4b when the user of the vacuum cleaner 1 grips the grip portion 4c and performs a reciprocating motion that moves the hand operating portion 4 in the front-back direction, for example. The restrictive change of is shown. The vertical axis is acceleration and the horizontal axis is time. FIG. 9B is an enlarged view of the horizontal axis in FIG. 9A, and is a diagram for explaining a change in acceleration for one cycle of reciprocation.

As shown in FIG. 9 (a), when the cleaning operation starts at time t1 and stops at time t2, the acceleration during that time changes substantially in a sine wave shape. The cleaning operation time TS (= t2-t1) corresponds to the acceleration detection time.
As shown in FIG. 9B, the waveform for one cycle of the reciprocating motion has an acceleration amplitude of a and a cycle of T. The period T is calculated by T = 1 / f, where f is an acceleration frequency detected by the acceleration sensor.

If this waveform is repeated over the cleaning operation time TS, the acceleration A (t) can be expressed by the following equation.
A (t) = a × sin (2πt / T) (Formula 1)
When the acceleration A (t) is integrated at time t, a velocity V (t) is obtained as shown in the following equation.
V (t) = − a × (T / (2π)) × cos (2πt / T) (Formula 2)
A × T / (2π) = B in Formula (2) (Formula 3)
Is the maximum value of the speed in the reciprocating operation, and B in Equation 3 corresponds to the reciprocating speed information.

When the velocity V (t) is integrated at time t, the displacement amount X (t) in the front-rear direction from the reference position of the reciprocating operation is obtained as in the following equation.
X (t) = − a × (T / (2π)) ^ 2 × sin (2πt / T) (Formula 4)
Here, ^ represents a power.
A × (T / (2π)) ^ 2 = A in Formula (4) (Formula 5)
Is the amplitude on one side of the displacement amount of the reciprocating motion, and corresponds to the reciprocating amplitude information. That is, 4A corresponds to the cumulative movement distance when the suction port body 2 is reciprocated once (T seconds).
Therefore, the cumulative movement distance XT of the suction port body 2 during the cleaning operation time TS is expressed by the following equation.
XT = 4A × TS / T (Formula 6)
On the day of the cleaning operation (today), when the cleaning operation is performed intermittently, the cumulative movement distance XT of the day is the sum of the cumulative movement distances XT expressed by Equation 6.

Although the reciprocating speed information is the maximum speed value B in the reciprocating operation, the average speed (= 4 A / T) obtained by dividing the accumulated moving distance 4A when the reciprocating movement is performed by T seconds may be used as the reciprocating speed information.
Further, when the reciprocating speed information in each reciprocating operation is different when the reciprocating operation is performed a plurality of times over the cleaning operation time TS, the average value, median value, maximum value, minimum value, etc. of each reciprocating speed may be used as the reciprocating speed information. .
In addition, on the day (today) of the cleaning operation, when the cleaning operation is performed intermittently, the average value, median value, maximum value, minimum value, etc. in each cleaning operation are averaged by the number of the cleaning operations performed intermittently. The value may be used as the reciprocating speed information.

  The hand control unit 4d calculates the accumulated movement distance and the reciprocating speed information from the sine change of the acceleration of the hand operation unit 4 detected by the acceleration sensor 4b, and stores the information in the information storage unit 30 of the wireless tag 21. In the information storage unit 30, the cumulative movement distance information and the round-trip speed information on the day (today) on which the cleaning operation was performed, the cumulative movement distance information for each day of the week, the round-trip speed information, and each week of the month Accumulated moving distance information and reciprocating speed information are stored. When the wireless tag 21 on the hand control unit 4d detects the proximity of the portable information terminal 24, the wireless tag 21 wirelessly transmits the accumulated movement distance information and the round-trip speed information received from the hand control unit 4d to the portable information terminal 30. Display on display 24a

Embodiment 2
In the first embodiment, the case of cumulative travel distance information and reciprocating speed information is shown as information to be displayed on the display unit 24a of the portable information terminal 24. However, in the second embodiment, the cleaning skill level is ranked. As a result, as a result of scoring the skill level of cleaning, the point that the highest score information and advice information so far are displayed is different.

  FIG. 15 shows information displayed on the display unit 24 a of the portable information terminal 24. Results of ranking cleaning skills (charisma housewives), results of scoring cleaning skills (90 points), maximum score information so far (95 points) and advice information (speed of moving the brush back and forth) If you take a little more slowly, you can get more trash.) A plurality of preset cleaning skill ranks (new housewives, master housewives, charismatic housewives, etc.) are provided, and the cleaning skill rank is displayed from the scoring results of skill levels.

FIG. 16 shows an instantaneous change in acceleration detected by the acceleration sensor 4b when the suction port 2 collides with an obstacle such as a wall. The vertical axis is acceleration and the horizontal axis is time. A peak value in an instantaneous change in acceleration within a 100 ms period determined from an experimental value is detected. Threshold values A and B are set in advance, and the number of times that the peak value in the instantaneous change in acceleration exceeds the range from threshold values A to B is counted. Here, the instantaneous change in acceleration refers to a change in acceleration over time in which the acceleration changes in the positive and negative directions within a time of 100 ms.
In FIG. 16, the peak value in the instantaneous change of the acceleration within the period of 100 ms determined from the experimental value is detected, but the number of times exceeding the thresholds A and B may be counted regardless of the time.

FIG. 17 is a diagram showing information on the hand control unit 4d side for determining the skill level of cleaning and how the portable information terminal 24 side performs data processing based on the information.
Based on the difference between the reciprocating speed information and the optimal reciprocating speed information, the hand control unit 4d classifies into the classes of A: slowly, B: slightly slow, C: standard, D: slightly fast, E: fast, The cleaning operation time in the class is calculated. For example, the original control unit 4d calculates the reciprocating speed information from the sinusoidal reciprocating motion of the acceleration sensor 4b, classifies the information into the classes A to E based on the difference between the reciprocating speed information and the optimal reciprocating speed information, The cleaning operation times classified into the classes are integrated and stored in the information storage unit 30.
Further, the hand control unit 4d stores the number of times that the peak value in the instantaneous change in acceleration detected by the acceleration sensor exceeds a preset threshold value in the information storage unit 30 as F: wall collision detection number.

The portable information terminal 24 side receives the cleaning operation time information of the reciprocating speed information classified from class A to E and the number of wall collision detections F, and uses the received data to obtain a score P that is a standard of proficiency Is calculated. It is evaluated that the proficiency level is higher as the ratio of the cleaning time classified into C: standard class is larger than the total cleaning time. Moreover, it is evaluated that the proficiency is higher as the number of wall collisions is smaller.
As an example of calculating the score P, the score using the reciprocating speed information is PV (full score of 50), the score using the number of wall collisions is PC (full score of 50), and the score P is calculated as the sum of PV and PC. .

An example of a method for calculating the score PV using the reciprocating speed information will be shown. Cleaning time TA classified as class A, cleaning time TB classified as class B, cleaning time TC classified as class C, cleaning time TD classified as class D, cleaning time TE classified as class E Then, the score PV using the reciprocating speed information is calculated by the following equation.
PV = 50 × TC / (TA + TB + TC + TD + TE) (Formula 7)
The total cleaning time TT is expressed by the following equation.
TT = TA + TB + TC + TD + TE (Formula 8)

The example of the calculation method of the score PC using the wall collision frequency is shown. When the number of wall collisions is F (times) in the total cleaning time TT (minutes), the number of collisions FA per unit time is calculated by the following equation.
FA = F / TT (Formula 9)
PC = 50 × (1-FA / 10) (Formula 10)
The score P is calculated by the following formula.
P = PV + PC (Formula 11)

The score P is assigned to a preset cleaning skill level (new housewives, master housewives, charismatic housewives, etc.), and the cleaning skill rank and the skill level scoring results are displayed on the portable terminal. In addition, the portable terminal stores past scoring information and the previous cleaning skill rank and displays the information.
Correspondence between the score P and the cleaning skill level rank (new housewife, master housewife, charismatic housewife, etc.), which is a preset rank range, is set as follows, for example.
Score P less than 80: New housewife.
Score P is 80 or more and less than 90: Master housewife.
Score P 90 or more: Charismatic housewife.

  Although the scoring process is performed on the portable information terminal 24 side, the scoring process may be performed on the electric vacuum cleaner 1 side.
