Fig. 8 is a cross-sectional view showing the internal structure of the sweeping state detecting sensor 32 provided in the sweeping state detecting substrate 58. The eighth (a) is a sweeping state t when the posture of the sensor 32 is kept vertical (Y direction), and when the posture of the eighth ("sweeping state detecting sensor 32" is maintained horizontal, the movable tab 40 is displayed. Fig. 9 is an explanatory view of the mounting between the cleaning state detecting sensor 32 and the cleaning state 11 201204305 detecting the substrate 58. The cleaning state detecting sensor 32 is configured by a slightly circular electrode flat portion 37C, 38C; the slightly concave two-electrodes 37, 38 are composed of electrode side portions 37 &, 38a, 38b which erect the outer edge of the electrode flat portion 37c 38c, and, for example, a spherical movable tab 40 (movable body), which is electrically conductive The two electrodes 37 and 38 having a slightly concave shape are opposite to each other with a concave side, and are slightly parallel with an interval therebetween. The outside of the two electrodes 37 and 38 is fixed by a mold 39.

When p 37a and 38a or 37b and 38b are turned on via the movable tab 40: output sweep The state detects the signal of the sensor 32. The output of this signal is described later. Since the cleaning state detection sensor 32 is included, the movable body 40 is changed in accordance with the moving direction of the handle hose 3 in the cleaning operation of the electric vacuum cleaner 100, and the detection state of the sensor 3 can be detected in a simple configuration. Vibration. Knowing the state to detect salty; ig $. When Han Yingyi 32 is arranged as shown in Figure 8(a), in the sweeping action of the electric f vacuum cleaner 1〇0, the direction of movement of the handle hose 3 ( z direction) The movable tab 4G mainly moves in the z direction. The periphery of the electrode side portions %, b 38a, 38b is a circular 'movable tab 4'. It moves inward in the γ plane. When this movement, the tab 4 is movable. In some cases, the conduction between the electrodes 37 and 38 is cut off from the electrodes 3? or 3, =. On the other hand, when the sweep 32 is arranged as indicated by the 8th (8) circle, the sweep of the same moving 2 (10) is also performed at this time. In the operation, the handle (the direction) of the handle hose 3 is moved by the movable piece 4. On the surface of the electrode flat portion 37, the main 12 201204305 is moved in the z direction. However, since the diameter of the movable tab 4 is larger than the electrode plane The distance between the portions 37c and 38c is small, and it is difficult to conduct through the movable tab 40 when the movable tab 4 is moved. The electrodes 37 and 38. Therefore, when the sweep detecting sensor 32 is disposed as shown in Fig. 8(a), it is easy to detect the vibration in the moving direction of (4) + u 3 . The sweep detecting sensor 32 is mounted to the sweeping state. When the substrate 58 is detected and the lid portion 53 is on the upper side (in the case of the eighth (a) and ninth views), the electrode flat portions 37c and 38c are parallel in the vertical direction (γ direction), and the electrodes 37 and (10) are opposed to each other. The direction is the vertical direction in which the front and rear directions (Ζ direction) of the handle hose 3 are moved back and forth by the grip portion 52 in the user's sweeping. The electrode side surface portions 37a and 37bu of the electrode 37 and the electrode side surface portions 383 and 3 of the electrode 38 are connected to the lead wire 37d and the m lead wires 37d and 38d, respectively, and the cleaning state detecting substrate 58 is soldered. The sweeping state detecting sensor 32 is mounted on the cleaning state. The substrate 58 is detected. The cleaning state detecting substrate 32 can be attached to the cleaning state detecting substrate 58 by screws or the like. The cleaning state detecting sensor 32 can be mounted to the cleaning state detecting substrate 5 8 . The cleaning state detecting sensor 32 is mounted to the cleaning state detecting substrate 58. 'The direction in which the electrodes 37 and 38 of the cleaning state detecting sensor 32 are opposed (X: direction) and the normal direction of the mounting surface of the cleaning state detecting substrate 58 (X direction): When the 'sweeping state is detected, the substrate is detected. 58 is supported by the inside of the handle hose 3, and the normal direction of the mounting surface of the scan-like cancer detecting substrate 58 is moved back and forth. The front-rear direction of the hose 3 is perpendicular to the left-right direction. By arranging the state detection substrate 58 and the cleaning state detection sensor 32 in this manner, the movement of the handle hose 3 is moved back and forth (Z direction) with respect to the user in the direction of the user's movement. The movable tab 40 of the device 32 is rocked in the γ z plane centering on the front and rear directions (Z direction) in the motion space 64. In other words, the movable contact piece 40 is displaced in the movement space 64 in accordance with the movement direction of the handle hose 3 in the cleaning operation of the electric vacuum cleaner 》 [Configuration of the electric circuit] Fig. 11 is a first embodiment according to the present invention. The circuit configuration diagram of the electric vacuum cleaner of the example. The electric sweeper of this embodiment is constituted by four parts of the cleaner body 5, the handle hose 3 + the hose 4, the extension tube 2, and the suction device.

In the standard mode action switch, 'the standard strong mode and the standard weak type' can be switched by pressing the switch. The wheel of the standard strong mode is operated by a solid-state 1 GGGW (watt) rotating motor 19. The output of the standard strong mode is operated at a fixed 500 W (watt), and the rotary motor 19 <> sw4 stops the switching of the electric blower 9 and the motor 19. When the (0N) switches SW1, SW2, SW3, and SW4 are pressed, respectively, the circuits between the switches and the resistors R7, R8, R9, and R10 connected in series are closed. When the push is released, the switches SW1, SW2, SW3, and SW4 open the circuit between the switches and the series-connected resistors R7, R8, R9, and R1 0. Therefore, in the state where SW1, SW2, SW3, and SW4 are turned off without pressing 15 201204305, only the circuit of the resistor R6 is closed. According to the 0N (on) state of the switches SW1 to SW4, the voltage is divided by the built-in resistors R4 and R6 in the circuit on the side of the cleaner body 5 (when the switches swi to SW4 are all off), or R6 and The voltage difference between the shunt resistor between R7, R8, and R9 'R1〇 and R4 (when any of switches SW1 to SW4 is -10) changes the input voltage of microcomputer 29. The microcomputer 29 determines the operation mode based on the input voltage and controls the supply of electric power and the motor Μ of the electric blower 9 in accordance with the state of the switches SW1 to SW4 0M (on) of the operation switch 8.

The sweep state detecting device is configured to output the overlap signal voltage outputted from the sweep state detecting sensor 32 to the output of the sweep detecting sensor 32. The circuit eR1 is a pull-up resistor, and R2 and R3 are compared. The voltage division of the reference voltage of the device cp is shown in Fig. 12. The detection signal of the detection state detecting sensor 32 is generated. When the two electrodes 37, 38 of the sweep state detecting sensor 32 are connected via the chip 4, they are connected in series to the sweep state detecting sensor 32 to be connected in parallel with the shunt resistor on the side of the operation switch 8. Then, 16 201204305 is supplied to the comparator CP and the microcomputer 29 by these parallel combined resistors and the history, which are placed on the side of the cleaner body 5 (five) resistor r4, and the divided voltage of the DC voltage supplied from the constant voltage source '28. On the other hand, when the movable tab 4 of the cleaning state detecting sensor 32 does not contact the electrode of at least one of the two electrodes 37 38, the circuit of the conduction (four) 'resistance R5 between the two electrodes is open. As a result, the divided voltage of the DC voltage supplied from the constant voltage source 28 is supplied to the comparator CP and the microcomputer 29 by operating the shunt resistor on the side of the switch 8 and the resistor R4 provided on the side of the cleaner body 5. This voltage is different from the voltage between the moving tabs 4° conducting the two electrodes 37, 38. Next, the operation will be described.

For example, 'the state is stationary in the state of 8 (a) In the case where the circuit is closed, X is maintained as shown in Fig. 8(b), and the movable contact 4 does not contact the electrode 38' to maintain the open circuit dynamics as if it is stationary while rotating around 90 degrees around the z-axis. When the cleaning operation is interrupted, the operating state of the electric vacuum cleaner, that is, when the electric motor 18 201204305 and the motor of the brush motor are maintained in the driving state are interrupted, the vibration generated by the electric blower 9, the motor 19, and the rotating brush during driving is It is transmitted to the sweeping state detecting sensor 32 via the floor, the table, the wall, or the like, or via the hose 4, the extension pipe 2, etc. Further, the 'handle hose 3' is generated by the electric pumping machine 9 in the drive. The airflow flowing in the vicinity of the hose 4, the softening s 4, the vortex inside the extension pipe 2, and the vibration generated by the hose [extending the conflict of the inner wall of the S2, via the hose 4, the extension pipe 2, etc. Sometimes pass v to sweep In addition to the state detecting sensor 32, the vibration transmitted to the sweeping state detecting sensor 32 is detected by the load sweeping state detection salty |3|q 9 λα # , and the sensing state of the sensing device 58 is transmitted. The cleaning state detecting substrate 58, such as the drawing of the loading surface of the first sensor 32, is connected to the paper in the vertical direction on the two sides (reverse side) between the inspection surfaces. In addition, the upper end of the sweeping state detection wide 8 is the upper star of the elastic body, and the upper rib is maintained. The bottom surface of the segment 55 is slidably connected to the mountain direction, the lower scoop is swept, and the motion model of the substrate 58 is detected. The W state is shown in Fig. W. The cleaning state detecting substrate 58 of the cleaning state detecting sensor 32 is modeled by a particle having a weight of 1 m. Fan

For the mass point of the model weight m of the first drawing, the equation of motion when the vibration of the external force F 19 201204305 is applied in the Z direction, as is well known, the time is t, which can be expressed as follows.

Md2Z/dt2 = -ydZ/dt-kZ + F (Formula 1) The product of the mass m of the left-handed mass point and the second-order differential of the time t related to Z'. The first term is the frictional force, the velocity of the particle (related to The product of the first-order differential of z at time t and the number of motor (four), the second term on the right is the restoring force, the product of the Z-direction displacement and the elastic constant at the beginning of the equilibrium point, and the third term on the right is the external force of the vibration. The periodic force of a sinusoidal change. Equation 1 returns to the following differential equation. d2Z/dt2 + 2bdZ/dt + (〇〇) 2Z = F〇COS(pt) (Formula 2) Here, 2b=W /m (Formula 3) (ω 〇)2 = k/m (Formula 4) F = m F 〇 cos (pt) (Expression 5) As shown in the equation 5, the external force F is a vibration in which the sinusoidal change is performed in the mu month sheep p (the frequency of the external force F is 2; r times). The solution of Equation 2 is as follows. Z=Aexp(-bt)cos(ω t+ ) Here, a) + Bcos(Pt-y?) (Equation 6) ω 2 = 〇)2-b2 (Equation 7) β-FO/'/~(( ^〇)2-p^)2K2bp) 2) u ^

Un (magic = 2bp / ((6J〇) 2 - ρ2) (Equation 9) The eXp of the first term on the right side of Equation 6 represents the function of the number of the right side of the equation 6 of the formula 6. '丁'..., external force The general solution of F, shows the 10th 20 201204305 Figure: The natural vibration (or free vibration) of the sports 。 type. As shown in Equation 7, the ", k, &quot;. Equation 6 =:, the special force F Solution, the table item is based on the external movement. The forced vibration of the frequency vibration on the right side of the right side is also at any time. The door has a vibration. The initial condition of any movement, due to the 2nd: right/number function decays, after a certain amount of time. Only the item is left. The natural vibration attenuation friction coefficient of the first item on the right side is "the amplitude of the forced vibration caused by the medium 3 ', and the resonance coefficient "" increases the vicinity of the 匕 (maximum), that is, the resonance occurs. When b is changed to 匕/, the maximum degree of vibration (the rapid degree of resonance), the angular frequency of F is..., according to Equation 8, the square of the amplitude of the forced vibration is inversely proportionally attenuated. In addition, as will be described later, In order to suppress the vibration detection of the action of I: =, it is preferable that the friction coefficient is Tao, and at this time, the size becomes smaller. Therefore, the angular frequency P of the external force F is smaller than "hour". The root, the amplitude B of the forced vibration can be approximated to F〇/W, and the value of p is constant. Therefore, in order to suppress the vibration detection that is not accompanied by the operation during the sweep, it is preferable to reduce the friction coefficient #. The vibration of the middle movement is generated by the movement of the user's 3 in the front-rear direction (Z direction), and the vibration period; the time required to go back and forth in the front-rear direction of 3 is considered to be about 1 second to several seconds because of the movement in the sweeping The angular frequency of the vibration is ~6 [rad] or so. In the other way, the lowest of the (4) of the electric blower 9 and the rotating brush * used by the electric blower 9 is considered to be generated by the rotation of the rotary cymbal. When the rotation speed is 10 sec/sec, the angle of the rotation of the rotating brush during the interruption of the motion is 21 〇 [rad]. Therefore, in order to suppress the vibration during the interruption of the detection sweep operation, ω 〇 It is preferable to select a value smaller than 6. Therefore, as shown in Formula 4, it is necessary to reduce the elastic constant k or increase the mass m. It is not desirable to increase the mass of the best cutting body in a vacuum cleaner that requires weight reduction. The elasticity of the upper pressure retainer 56 is often When the cover detecting hose 58 is twisted or fixed or joined to the frame of the handle hose 3, the elastic body supporting the sweeping state detecting substrate 58 is the frame of the handle hose 3. The handle hose 3 is self-contained. The elastic constant 1 of the frame body is significantly larger than the elastic constant of the carbamate of the upper pressure holder 56, and the value of (4) is also larger than the latter. Therefore, the substrate 58 to the handle hose is detected more than the fixed sweeping state. In the case of the frame of 3, the above-mentioned pressure holder 56 is used as a standard, and the amplitude B of the forced vibration generated by the high-frequency external force is small. In other words, the vibration in the interruption of the high-frequency external force is absorbed by the upper pressure holder, and it is difficult to conduct to As a result of the cleaning state detecting substrate 58 and the cleaning state detecting sensor 32', it is possible to suppress vibration detection that is not accompanied by the cleaning operation. In the sweeping operation, the user-operated handle hose 3 moves back and forth (Z direction) back and forth, and the front and rear directions of the handle hose 3 are required to travel back and forth for about 1 second to several seconds. The sweeping state detecting sensor 32 detects the vibration generated by the back and forth motion 'detecting the sensing portion via the sweeping state', and dials the nickname of the voltage change to the microcomputer 29. The microcomputer that receives the signal 判断 determines that the target m is V. In the electric blower 9 and the electric motor 19, the setting operation is controlled by the operation switch 8. When the operation of the electric blower 9 and the electric motor 19 that continue to be driven is interrupted, the vibration transmitted to the handle hose 3 is suppressed and transmitted to the cleaning. 22 201204305 The movable detecting piece "32" of the state detecting substrate 58 and the cleaning-out sensor 32 is in the operating space 6 疋, and the sensing state detecting unit 31 is detected by the cleaning state.

The sweeping state. The movable bucket detects the vibration generated by this back and forth motion from the 1 4 state 32. The state signal is cleared to the microcomputer 29. By receiving this (four) ^ =31, the round and the power repeatedly change action... This "the tiger's microcomputer 29, judges the sweeping machine as a reopening, and controls the setting operation of the electric blower 8. In the electric vacuum cleaner having the operation switch as described above, the sensing portion is detected by the cleaning state, and the frame of the soft controller is read by the elastic body, and the elastic constant ratio of the sexual body is In the above-mentioned, the elastic constant of the frame of the four 釈s is small, and the vibration of the vibration-detecting main body during the interruption of the cleaning operation can be oscillated at a high frequency in the vibration of the singer. In addition to the second-sweeping state detecting sensor, since there is a movable tab that is displaced in accordance with the moving direction of the handle hose in the sweep of the electric vacuum cleaner, the vibration of the sensor can be detected by detecting the sweeping state with a simple configuration. In the dust-removing two-handle hose, the damper Μ·0 device is installed, and the sweeping state detection based on the movement of the handle hose is suppressed during the cleaning operation of the electric suction machine. 23 201204305 Induction unit operation 'non-detection target> 固有 natural vibration The sorrow and the vibration of the external force of the object can be right-handed to the "mountain", and the detection of the detection state of the detection state is efficiently detected on the 6-u. The side of the branch's side can be folded by the conductive wall provided on the inner wall of the handle hose, and the other side is supported by the elastic body. The sweeping state detects eight electrodes, and there is a gap and the opposite is movable. The electrode is electrically connected to the electrode or the side surface of the electrode connected to the electrode and the electrical periphery is rotatably and electrically conductive, and the electrode is vertical and the % of the electric milk and the press are removed. The direction perpendicular to the direction of movement of the handle hose and the direction of the movement is such that the above-described operating space is formed in a substantially cylindrical shape in the radial direction longer than the above-mentioned electrode in the longitudinal direction of the bottom surface and the upper surface. Miscellaneous s μ t In addition, it is detected by the simple configuration of the detection of the detection of the burglary. The 13th ® is pre-memorized to the form of the microcomputer 29 (memory 1). The value judges which of the switches SW1 to SW4 is pressed. That is, the operation value of the operation switch 8 is judged by using the form value ', 轵M de μ, and the phantom detects the signal of the sensing 〇ρ 31 according to the state. Judging the sweeping state. Also, the heart of the #人s 4疋 No connection to the vacuum cleaner body 5 is judged by this form value. _ 4 _ is the voltage signal waveform of point A and point B in the 11th figure, The display hose 4 is connected to the cleaner body 5, and the voltage signal waveform of the point A of the operation switch 8 is not pressed, and the signal voltage of the operation switch 8 and the signal voltage of the sweep state detecting sensor 32 are superimposed. When the sensor 32 repeats the ON (ON) and 〇 FF (OFF) states 24 201204305, the signal voltage of 1·01V to 1.53V is output. This output waveform is output to the sweep status detecting device 33. The sweep status check The output device 33 determines the threshold value by the ON and OFF of the comparator CP (1.25^ The reference 'comparator cp outputs the voltage waveform at point B. The ON and OFF determination thresholds are the voltages at which the DC voltage of the voltage source 28 is divided by R2 and R3. The ON and OFF determination thresholds higher than the comparator are generated ( At a voltage of 1.25 V), when the output of the comparator cp is 0 V and a voltage lower than the 〇M of the comparator CP and the OFF determination threshold (1.25 V), the output of the comparator CP is 5 V. As described above, due to the overlap The signal voltage of the operation switch 8 and the signal voltage of the sweep state detecting sensor 32 are transmitted from the handle hose 3 to the cleaner body 5 (four), and the signal line 2 can be. The signal line of the common potential of the strip is connected to the line of the resistance side of the operation switch 8 by the block of the hose 4 + hand # answer + α e 4 10 in soft 11 in Fig. 11. The other one is connected to the line on the switch SW1 to SW4 side of the operation switch 8, and the signal voltages in this line overlap. Therefore, it is possible to reduce the number of signal lines and obtain an inexpensive electric vacuum cleaner. Figure 15 shows the sweeping state detected salty.愧m should be.

The blower 9 and the electric motor blower g of the suction device 1 are in the middle of driving, and the electric motor 19 of the material Lei Cong drives the micro-electric controller (control device) 29 ^ ^ ^^ ^ φ ^ The reduction is set separately: 3⁄4 knows that the electric blower 9 is driven, and the first reference value of the motor 19 of the eight-piece 1 and the sweep Φτ in the judgment interrupt ISI Ά Ο η 〃 are judged to be reopened and the electric fan is lowered. 9 and inhalation of electric power it ^ m 9 « % drive of the machine 19 or return to the second reference value before the stop, these reference orders. ° Hidden in the microcomputer 29 (memory device) to determine the interruption of the sweeping action For example, the remainder of the cuckoo is set as follows: The critical v 1W value (the first reference value) of the 仏 voltage (pulse) number 设定 is set to 11. Χ &lt;11 (Condition 1) The pseudo-L boundary value (third reference value) of the determination condition continuous satisfaction order γ is set to 15. Y2 15 (Condition 2) That is, when the number of signal voltages (pulses) is less than 11 times every 1 〇〇ms (milliseconds) (scheduled time) is satisfied 15 times, (4) is the operation interruption. The determination that the sweeping action is reopened is set, for example, as follows. The threshold value (second reference value) of the signal voltage (pulse) number X is set to 2. 2 (Condition 3) The critical value (fourth reference value) of the number of consecutive conditions Y of the judgment condition is set to 4. Y ^ 4 (Condition 4) is the condition that when the number of signal voltages (pulses) is more than 2 times per 100ms (milliseconds) (both 26 201204305 fixed time), the sweep is interrupted. The action is reopened. Further, the third reference value and the fourth reference value are also stored in the microcomputer μ (memory device). ° The first reference value (=11) is set to be larger than the second reference value (=2). The third reference value (=15) is larger than the fourth reference value (=4). Therefore, yes. The cleaning operation is interrupted by the erroneous detection of the detection state detecting unit. </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> </ br> The electric suction used for the payment is followed by the flow chart description of the operation of the control device.

The operation of the induction device 1 32 does not detect the start of the operation, and the vibration of the state detecting sensor 19 is detected, and the motor blower 9 and the motor are activated (S4 is determined to be unproductive). The sensor does not detect the timing of the timing of the undetected timer (undetected time) is 1 sec., 疋 no bundle. The timing of this chronograph is 6 gram 禾,,, ° beam When it is not detected, the time sweeping is not detected. When the time is not detected, enter (10), clear: φ, and the state detection sensor does not detect the timer. ^The processing of the month % is carried out to S7, compared with The profit round-out signal counting process (the next 27 201204305 detection of the falling edge) starts. Next, the process proceeds to S8, and the measurement of 100 ms (established time) is started. Next, the process proceeds to S9, and it is judged that 100 ms (established time) has elapsed. After Oms (millisecond) (scheduled time), the process proceeds to S1 0, and the count value X of the comparator output signal occurring within 1 00 ms (established time) is compared with the first reference value. Next, the process proceeds to S11, and the process S10 is compared. The number of times Y of condition 1 is continuously satisfied and the second reference value. In SI 1 When the condition 2 is satisfied, the process proceeds to S12. In S12, the execution is determined to be changed to the EC0 (engineering change order) shutdown program. The ECO shutdown program determines that the sweep operation is interrupted, and the output of the electric blower 9 is operated regardless of the operation switch 8. The setting is reduced to 100 W. The control is changed to the EC 〇 shutdown program, and the process returns to S8. When the change is made, the EC 〇 shutdown program change process (si3) is performed, the output is changed to 100 W (S14), and the motor is stopped. The second diagram illustrates the flow chart, and judges that the sweeping motion 2 that has been determined to be interrupted is turned off and the drive of the electric blower 9 and the suction motor 1 is resumed or the control is returned to the state before the stop. The electric blower 9 and the suction motor 19 are in the state of reducing or stopping the driving state (8). The control of the motor 9 or the motor 19 is changed. Then, the electric blower detection state is detected and reduced @@, and after the control is changed, 4 Will not detect the motor fan 9 and the electric 乍 unstable electric device is not detected timing: 19: Whether the implementation is finished or not. This time is not 检 timer is not detected The time is continued until the timing is not detected = _S21, and the sweep detection state is not detected. When the timer is not detected, the process is continued. After the processing of 201204305 S21, the process proceeds to S22, and the comparator output signal counting process (falling edge) is started. Detected.) Next, proceed to S23 and start measurement of 1 〇〇ms (established time). Secondly, proceed to S24 and judge that 1 〇〇ms (established time) has elapsed. After l〇〇ms (milliseconds) (established) After the time), the process proceeds to S25, and the count value X of the comparator output signal and the third reference value which occur within 1 〇〇ms (established time) are compared. Next, the process proceeds to S26, where the number of times γ and the fourth reference value of the condition 3 are continuously satisfied in the comparison process. When S26 judges that it satisfies the condition of the second block 4', it proceeds to S27. S27 towel, the execution decision is changed to a coffee strong program. The EC0 strong program judges that the sweeping operation in the interruption is re-opened and returns the control of the output of the electric blower 9 to the state before the decrease. . When the program is unchanged and the EC is reluctant, return to S23. At the time of the change, the (4) strong program change process (S28) is performed, the rim M9cn is changed (S29), and the electric vacuum cleaner of the rl which starts the rotation of the motor is switched, and the drive-out of the drive-out of the electric blower is switched. The threshold value of the heartbeat removal state and the number of operation switch wires of the control unit of the control unit of the signal state dynamics sweeping state check engine and the operation state of the electric blower and the electric state detection state detecting device, and the memory sweeping operation can be reduced. ^ Stopping on the side of the vacuum cleaner body, the signal is easy to malfunction. Moreover, since the configuration is simple and the cost is low, it is determined that the sweeping action of the electric vacuum cleaner 29 201204305 is interrupted due to the output signal voltage of the root one in the motor drive of the induction driving and the suction device. # ...Remember to reduce or stop the first reference value of the electric blower and the sucked motor output, and judge the middle of the nr machine to be cleared (4) 2 reference value, the quasi time of the sweeping operation is extended, and the sweeping action is reopened. When the reference time of the judgment is shortened or the reference time for the interruption of the sweeping operation is shortened and the base rate of the sweeping operation is reopened, the judgment reference time such as pg ^ g &amp; extended drought time can be set and is convenient to use. Further, the control device detects the movement of the handle hose according to the number of pulses of the signal electric dust outputted by the sensing unit in the sweeping state, and the number of comparison pulses and the reference value of 帛1 are lower than the first reference value. When it is judged that the cleaning operation of the electric vacuum cleaner is interrupted, and the second reference value of the pulse number dial is compared, the number of pulses is 帛! When the reference value is equal to or greater than the reference value, it is judged that the cleaning operation of the electric vacuum cleaner that has been determined to be interrupted is reopened, and the setting of the first reference value is larger than the second reference value "can suppress the interruption of the cleaning operation due to the erroneous detection of the detection state detecting portion. In addition, since the judgment criterion of sweeping and reopening in the sweeping operation is loose, the sweeping action can be reopened immediately and is convenient to use. In addition, when the number of pulses is compared with the third reference value and the number of pulses is lower than the first reference value for each predetermined time, and the control device determines that the cleaning operation of the electric vacuum cleaner is interrupted, When the number of pulses is compared with the second reference value and the number of pulses is equal to or greater than the second reference value, and the number of pulses is equal to or greater than the fourth reference value, it is determined that the cleaning operation of the electric vacuum cleaner that is determined to be interrupted is reopened. When the third reference value is set to be larger than the fourth reference value, it is possible to further suppress the determination in the interruption of the cleaning operation caused by the erroneous detection of the detection state detection unit, and to remove the detection from the interruption of the interruption of the 201204305 operation. Easy to use sound. (4) The base shirt 'sweeping action can be re-opened immediately. After the initial tb device's change the control of the electric blower or motor, the initial comparison pulse number and the second value of the second base value, or 疋, the initial comparison pulse number: Ray: After the predetermined time, the counting of the number of pulses starts, the electric blower or the brush; when the operation of the motor is unstable, the motor is not detected, and the cleaning operation state is correctly determined. [Second Embodiment] In the first embodiment, one microcomputer 1 (memory device) stores one first reference value, a flute 9 device, a 隹2 value, a third reference value, and a fourth value. The reference value, but in the second embodiment, the configuration of these reference values can be changed. Fig. 18 is an explanatory diagram of a reference value changing device for changing the first reference value, the second reference value, the third reference value, and the fourth reference value. In the microcomputer 29, a plurality of second reference values, third reference values, and fourth reference values of the "pre-memory first reference value" are combined in the memory device 29a. The memory device 29a is composed of R〇M (read only memory). Then, the first reference value, the second reference value, the third reference value, and the fourth reference value 5 for use in the electric vacuum cleaner temple are recalled in the memory device 29b. The memory device is composed of "Μ (random access memory). The signal voltage at point A in the square of the cleaner body 5 (see Fig. 11) is input to the reference value changing means 29c, and based on the signal voltage, the memory in the device 29a is remembered. One of the combinations of the plurality of memories is stored in the memory device 29b. When the power line 7 of the electric vacuum cleaner 100 is connected to the commercial AC power source 24, none of the switches (SW1 to SW4) in the operation switch 8 of Fig. 11 31 201204305 The Λ point voltage of the ON state is input to the reference value change 裴29c of the microcomputer 29. The Α point voltage at this time becomes the DC voltage of the constant voltage power supply 28 to operate the resistance R6 of the switch 8 and the resistance R4 of the cleaner body 5 According to the input voltage, the reference value changing means 29c converts the reference value data of the standard combination among the combinations of the reference values stored in the recorded 29a to the memory device 29b. Thus, the electric vacuum cleaner 2 operates. The combination of the reference values stored in the memory device 29b is used to determine whether the sweep operation S or the sweep operation is reopened. - According to the user's preference, the combination of the reference values stored in the memory device 29b, When the combination of other reference values stored in the memory 429a is used, when the power supply line 7 of the electric vacuum cleaner 100 is connected to the commercial alternating current power supply ^, any switch (SW1 to other 4) of the operation switch 8 is (10), The power supply line 7 is connected to the commercial AC power supply 24. Thus, the resistors R7 to R10 that are connected in series by the 0N switch, the parallel combined resistance of the resistor and the resistor R6, and the resistor R4 of the cleaner body 5 are divided by the voltage source 28 The voltage of the DC voltage is input to the reference value change device. This voltage is different from the voltage of any switch (10)~ that is not 0N. According to the input voltage, the reference value is changed to i29c, from the memory device... In the reference combination of the internal memory, a set of combined reference value data is memorized to the memory device (5) b. Since there are four operation switches, the voltage input to the reference value changing device 2〇c also has four different power avoidances. It is selected from the four reference value combinations stored in the memory device _. Therefore, the operation command of the electric vacuum cleaner _ is combined with the reference value stored in the memory device 29b to determine whether the cleaning operation is interrupted or the cleaning operation is performed. Therefore, the i-th reference value, the second 32 201204305 reference value, the third reference value, and the fourth reference value can be changed. Further, the 'memory device 29b is configured by a RAM, and each time the power source line 7 is connected to the commercial AC power source 24, The data of the memory device 29b is updated based on the input voltage of the reference value changing device 29c. However, the memory device 29b may be configured with an EPROM (erasable programmable read only memory). Since it is composed of epr〇m The line 7 is connected to the commercial AC power source 24, and which switch of the operation switch 8 does not need 0N, which is convenient to use. Therefore, the device reference value changing device for changing the first reference value and the second reference value can be customized according to the user's preference. Adjust the reference time of the interruption judgment of the sweeping action, which is convenient to use. Further, since the second reference value changing means for changing the third reference value and the fourth reference value is provided, the reference time for the re-opening determination of the cleaning operation can be adjusted according to the user's preference, and it is convenient to use.
