14 is another example of the hand grip part 330 provided with the detection part 400.

The first detection unit of the detection unit 400 includes a first capacitance sensor 417 for detecting a straight moving direction and a straight moving force such as forward and backward of the slide unit 334, and the second detection unit includes a slide unit 334 And a second capacitance sensor 427 for detecting a rotational movement direction and a rotational movement force such as left and right rotation.

The structure of the hand grip part 330 having such first and

second capacitance sensors

417 and 427 will be described.

The hand grip part 330 includes a shaft member 350 mounted to the slide part 334.

The shaft member 350 moves in a straight line along the guide part 332 in conjunction with the linear movement of the slide part 334. Here, the shaft member 350 is made of a flexible material.

In addition, the shaft member 350 further includes a contact member 350a capable of contacting the second capacitance sensor.

The first capacitive sensor 417 includes a first sensor 417a for sensing a straight direction corresponding to the forward, and a second sensor 417b for sensing a straight direction corresponding to the reverse, and a second electrostatic The capacitive sensor 427 includes a third sensor 427a for sensing a rotational direction corresponding to the right turn and a fourth sensor 427b for sensing the rotational direction corresponding to the left turn.

The first sensor 417a and the second sensor 417b of the first capacitive sensor are located at both ends of the shaft member 350.

Accordingly, when the shaft member 350 moves forward in association with the linear movement of the slide unit 334, the shaft member 350 is closer to the first sensor 417a and further away from the second sensor 417b. . As a result, the capacitance detected by the first sensor 417a increases, and the capacitance detected by the second sensor 417b decreases.

On the contrary, when the shaft member 350 moves backward in association with the backward movement of the slide unit 334, the shaft member 350 is further moved away from the first sensor 417a and closer to the second sensor 417b. . As a result, the capacitance detected by the first sensor 417a is reduced, and the capacitance detected by the second sensor 417b is increased.

That is, the moving distance of the slide part corresponding to the capacitance of the first sensor or the second sensor of the first capacitance sensor is stored in advance in the cleaner.

Although two first capacitive sensors are used here, it is also possible to detect the linear movement distance of the slide part with only one first capacitive sensor.

The third sensor 427a and the fourth sensor 427b of the second capacitance sensor are located at both ends of the contact member 350a provided in the shaft member.

That is, the third sensor 427a of the second capacitance sensor is located on the right side with respect to the shaft member, and the fourth sensor 427b is located on the left side with respect to the shaft member.

Accordingly, when the shaft member 350 rotates right in conjunction with the right rotation of the slide unit 334, the contact member 350a rotates in right direction in conjunction with the right rotation of the shaft member, and the contact member 350a is rotated by the right rotation of the contact member 350a. Is closer to the third sensor 427a and farther from the fourth sensor 427b. As a result, the capacitance detected by the third sensor 427a increases, and the capacitance detected by the fourth sensor 412b decreases.

On the contrary, when the shaft member 350 rotates left in conjunction with the left rotational movement of the slide unit 334, the contact member 350a rotates left in response to the left rotation of the shaft member, and thus the contact member 350a rotates through the third sensor 427a. Further away from and closer to the fourth sensor 427b. As a result, the capacitance detected by the third sensor 427a is reduced, and the capacitance detected by the fourth sensor 427b is increased.

That is, the rotation angle, which is the movement distance of the slide part corresponding to the capacitance of the third sensor or the fourth sensor of the second capacitance sensor, is stored in advance in the cleaner.

Although two second capacitive sensors are used here, it is also possible to detect the rotational angle of the slide unit with only one second capacitive sensor.

In this way, it is possible to detect the linear movement and rotation of the slide part using the first capacitance sensor and the second capacitance sensor.

Here, although the capacitive sensor is used as the first detection unit and the second detection unit, it is also possible to use a strain gauge that measures the degree of deformation when deformed by an external force applied through the shaft member or the contact member, and also detects the force or load. It is also possible to use a load cell.

15A and 15B illustrate still another example of the hand grip unit 330 provided with the detection unit 400.

The first detection unit of the detection unit 400 includes a first strain gauge 418 that detects a straight moving direction and a straight moving force such as forward and backward of the slide unit 334, and the second detection unit includes a slide unit 334 And a second strain gauge 428 for detecting a rotational movement direction and a rotational movement force, such as left and right rotation of the device.

The structure of the hand grip portion 330 having such first and

second strain gauges

418 and 428 will be described.

The hand grip part 330 further includes a body part, a cap part, a guide part disposed between the body part and the cap part, and further includes an operation member 360 mounted to the guide part.

The operation member 360 can be mounted to the guide portion by a flexible shaft member 360a).

Here, the operation member 360 is made of a joystick shape, and moves back, front, left, and right by the shaft member.

The first strain gauge 418 includes a first gauge 418a for sensing a straight direction corresponding to the advance, and a second gauge 418b for sensing a straight direction corresponding to the reverse, and a second strain gauge 428 includes a third gauge 428a for sensing a rotational direction corresponding to the right rotation and a fourth gauge 428b for sensing the rotational direction corresponding to the left rotation.

The first gauge 418a of the first strain gauge is located in front of the operating member 360, and the second gauge 418b is located behind the operating member 360.

Accordingly, when the operation member 360 moves forward, the first gauge is deformed by the operation member, and when the operation member 360 moves backward, the second gauge is deformed by the operation member.

That is, according to whether the first gauge and the second gauge are deformed and the degree of deformation, it is possible to know whether the movement direction intended by the user is forward or backward, and the movement distance intended by the user.

In addition, the vacuum cleaner is stored in advance with the straight movement distance of the cleaning tool assembly corresponding to the deformation degree of the first gauge and the second gauge of the first strain gauge.

The third gauge 428a of the second strain gauge is located on the right side of the operation member 360, and the fourth gauge 428b is located on the left side of the operation member 360.

Accordingly, when the operation member 360 moves to the right, the third gauge is deformed by the operation member, and when the operation member 360 moves to the left, the fourth gauge is deformed by the operation member.

That is, according to whether the third gauge and the fourth gauge are deformed and the degree of deformation, it is possible to know whether the rotation direction intended by the user is a right rotation or a left rotation, and also the rotation angle of the cleaning tool assembly intended by the user.

In addition, the rotation angle of the cleaning tool assembly corresponding to the deformation degree of the third gauge and the fourth gauge of the second strain gauge is stored in advance in the cleaner.

As such, it is possible to detect the straight movement and the rotational movement of the cleaning tool assembly by using the first strain gauge and the second strain gauge.

Here, although the strain gauge is used as the first detection unit and the second detection unit, it is also possible to use a capacitance sensor whose capacitance changes due to the movement of the operation member, and also use a load cell for detecting the force or load applied by the operation member. It is also possible.

It is also possible to use magnetic sensors and high frequency oscillation inductive sensors.

Here, the direction of the force is at least one of the front, rear, left, and right, the magnitude of the force is the displacement of the cleaning tool assembly, the movement distance when going straight and the rotation angle of the rotary type.

In addition, the direction of the force is determined by whether the value of the detection signal before the slide portion increases or decreases, and the magnitude of the force is determined by the difference between the detected value before the slide portion movement and the detected value after the slide portion movement.

The driving module 500 adds the moving force of the cleaner by driving the moving unit provided in the cleaning tool assembly based on the signal detected by the detection unit.

As shown in FIG. 17, when it is determined that the direction of the force acting on the handle part is the forward direction, the controller 510 controls the rotation direction of the pair of wheel motors in the first direction so that the cleaning tool assembly moves forward. If it is determined that the direction of the force acting on the handle part is the reverse direction, the cleaning tool assembly is moved backward by controlling the rotation direction of the pair of wheel motors in the second direction.

In addition, the control unit 510 checks the moving distance corresponding to the magnitude of the force acting on the handle part when moving forward or backward, checks the number of revolutions of the wheel motor corresponding to the identified moving distance, and pairs with the identified number of revolutions. To control the rotation of the wheel motor.

As shown in FIGS. 18A and 18B, when it is determined that the direction of the force acting on the handle part is a right rotation direction, the controller 510 controls the rotation direction of the pair of wheel motors in the first direction, but at different rotation speeds. When the cleaning tool assembly is turned to the right and the direction of the force acting on the handle part is determined to be the left turning direction, the cleaning tool assembly is controlled by controlling the rotation direction of the pair of wheel motors in the first direction with different rotation speeds. Turn left.

In addition, the control unit 510 checks the rotation angle corresponding to the magnitude of the force acting on the handle part during the right turn or the left turn, and confirms the number of revolutions of the pair of wheel motors corresponding to the identified rotation angle, respectively, Each channel controls the rotation of a pair of wheel motors.

The storage unit 520 may store a movement direction corresponding to the magnitude of the force, and store a movement distance (or rotation angle) corresponding to the amount of change in the magnitude of the force.

The storage unit 520 may store a detection signal corresponding to the initial position of the slide unit.

The driving unit 530 rotates each wheel motor connected to the pair of wheels based on the command of the control unit 410.

This allows the cleaning tool assembly to move back and forth or to rotate left and right.

In this way, by controlling the movement of the cleaning tool assembly in response to the user's intention, it is possible to reduce the horizontal load felt by the user by holding the handle of the cleaner, thereby improving steering performance, and the vertical imputation through the handle. By removing the load, the fatigue during the cleaning operation can be eliminated, and the convenience can be improved.

WB means the weight of the lower portion around the rotating part 729. That is, the weight of the cleaning tool assembly 720 is meant. WU means the weight of the upper portion around the rotating part (729). That is, the weight of the main body 710 and the handle portion 730.

Accordingly, the position of the main wheel 727 should protrude rearward. The protruding distance of the main wheel 727 is related to the design factor and steering performance of the upright cleaner. In other words, when the protrusion distance is increased, it is possible to safely prevent the rear tip of the cleaner, but the steering of the upright cleaner becomes a problem. It also hurts aesthetics by design.

The first detector 23 and the second detector 24 may output an electrical signal corresponding to the force applied from the user according to the manipulation of the handle part 20 of the user and transmit the electrical signal to the controller 40. More specifically, when a force is applied to the handle part 20 according to the manipulation of the handle part 20 of the user, the displacement of the control part (632 of FIG. 20) provided in the handle part 20 is changed, and the first detection part 23 is applied. ) And the second detector 24 may output such a displacement as an electrical signal of a corresponding voltage. The output signal may be transmitted to the controller 40.

The state sensor 30 may detect a current state of the cleaner, output an electrical signal according to the detection result, and transmit the electrical signal to the controller 40. As described above, the state detection sensor 30 may include an inclination sensor 31 or an acceleration sensor 32 to detect the inclination of the main body.

As described above, the obstacle sensor 33 may detect the obstacle 99 existing in the moving direction of the cleaner, output an electrical signal according to the detection result, and transmit the electrical signal to the controller 40.

The control unit 40 receives an electrical signal output from at least one of the input unit 10, the detection unit 22 of the handle unit 20, the state sensor 30, and the obstacle sensor 33 and according to the received electrical signal. The operation of the cleaner may be controlled by generating a control signal.

For example, the controller 40 may determine the speed or direction of the

wheels

42a and 42b of the cleaner according to the electrical signal transmitted from the detector 22 of the handle part 20. More specifically, the control unit 40 determines the magnitude of the force applied by the user to the handle unit 20 according to the electrical signal, and according to the determined first drive unit 41a or the right wheel (for driving the left wheel 42a). An operation of each of the second drivers 41b for driving 42b may be determined. The controller 40 may generate a control signal corresponding to the speed or direction of the

wheels

42a and 42b of the cleaner. The generated control signal may be transmitted to the corresponding

drivers

41a and 41b.

In addition, the controller 40 may receive information about the rotation speed or the rotation speed of each of the

wheels

42a and 42b from at least one of the first driving unit 41a and the second driving unit 41b. The controller 40 determines whether the

wheels

42a and 42b are operating at the required level based on the rotational speed or the rotational speed, and at least one of the first drive unit 41a and the second drive unit 41b according to the determination result. Additional control signals may be further generated to reset one operation. In other words, the control unit 40 may receive a feedback signal according to the operation of the driving

units

41a and 41b and adjust the driving

units

41a and 41b according to the feedback signal. For example, if the rotational speed or the number of rotations of the one or two

wheels

42a, 42b is lower than the required value, the controller 40 may increase the rotational speed or the number of rotations of the one or two

wheels

42a, 42b. The control signal may be generated, and the generated control signal may be transmitted to at least one of the first driver 41a and the second driver 41b. On the contrary, when the rotational speed or the number of rotations of the one or two

wheels

42a and 42b is higher than the required value, the controller 40 controls to reduce the rotational speed or the number of rotations of the one or two

wheels

42a and 42b. The signal may be generated, and the generated control signal may be transmitted to at least one of the first driver 41a and the second driver 41b.

The controller 40 transmits a control signal to the power supply 43 for supplying current to each of the driving

units

41a and 41b, thereby supplying current to each of the driving

units

41a and 41b, or for each of the driving

units

41a and 41b. The intensity or direction of the current supplied to the 41b may be adjusted, and each of the driving

units

41a and 41b may rotate at a predetermined speed in a predetermined direction according to whether the current is supplied, or the intensity and the direction.

The controller 40 may control the

respective driving units

41a and 41b not to be driven even when the handle jaw 20 is operated according to the electrical signal output from the state sensor 30. In addition, the controller 40 may control the operation of each of the driving

units

41a and 41b according to the electrical signal output from the obstacle sensor 33.

The controller 40 may include a processor and related circuits that may be implemented by one or more semiconductor chips and related components, and the processor may be a micro-controller unit (MCU).

The first drive part 41a may rotate the left wheel 42a at a predetermined rotation speed in a predetermined direction, and the second drive part 41b may rotate the right wheel 42b at a predetermined rotation speed in a predetermined direction. You can. The first driving unit 41a and the second driving unit 41b may be implemented as motors, and various motors, such as a DC motor, an AC motor, a cross-flow motor, a BLDC motor, a linear induction motor, or a step motor, may be implemented as motors. May be employed.

The first driver 41a may further include a sensor for detecting the rotational speed or the rotational speed of the left wheel 42a. Similarly, the second driver 41a may further include a sensor for detecting the rotation speed or the rotation speed of the left wheel 42a. The sensor of the first driver 41a may transmit the detected rotation speed or the rotation speed to the controller 40. As a sensor provided in the first driving unit 41a or the second driving unit 41a, various types of sensors that may be considered by a system designer may be employed to detect the rotational speed or the rotational speed of the motor.

The left wheel 42a may rotate in a predetermined direction and speed according to the operation of the first driver 41a. The right wheel 42b may rotate in a predetermined direction and speed according to the operation of the second driver 42b. The left wheel 42a and the right wheel 42b may be driven independently of each other. In other words, the left wheel 42a and the right wheel 42b may rotate at different speeds in different directions from each other. It is of course also possible for the left wheel 42a and the right wheel 42b to rotate at the same speed in the same direction.

According to the rotation of the left wheel 42a and the right wheel 42b, the cleaner 1 moves or rotates in a predetermined direction, so that the user can move or rotate the cleaner 1 with less force. Will be. Therefore, the convenience of cleaning using a cleaner can be improved.

The power source 43 may supply power to each component of the cleaner, and may also supply a predetermined current to the first driver 41a and the second driver 41b as shown in FIG. 49. The power source 43 may supply power to each component of the cleaner under the control of the controller 40. The power source 43 may be implemented as a battery such as a storage battery, and the battery may be a secondary battery that can be charged by an external commercial current. Of course, according to the embodiment, the battery may be a primary battery.

Hereinafter, various embodiments of a method of controlling an operation of a cleaner will be described with reference to FIGS. 51 to 57. The method for controlling the operation of the cleaner described below may be performed by using the cleaner of one or two or more embodiments of the above-described first to eleventh embodiments.

Hereinafter, a method of controlling the operation of the cleaner according to the first embodiment of the present invention will be described.

First, a user's force may be applied to the handle part in a state in which the cleaner is driven (S50). The force applied here may include at least one of a force for moving the control unit in the front-rear direction and a force for rotating the control unit.

At least one of the first detector and the second detector may detect a force applied by the user and output an electrical signal according to the detected force (S52).

The processor of the cleaner may receive an electrical signal and determine a rotation direction and a rotation speed of at least one of the left wheel and the right wheel according to the sensed force (S53). In this case, the moving speed of the cleaner according to the rotational speed of at least one of the left wheel and the right wheel may be determined to be smaller than a predetermined threshold. For example, the moving speed of the cleaner may be determined to be smaller than 1.5m per second. Accordingly, it is possible to prevent the deterioration of safety due to excessive high speed movement of the cleaner.

According to an embodiment of the present invention, an error may also occur due to the inaccuracy of the structure inside the handle part, as measured values by the sensor, for example, the first detection part and the second detection part. In other words, the neutral position of the sensor may be different from the desired position during fabrication. Therefore, the controller can prevent a malfunction due to an error by considering a section within a predetermined range as a dead zone based on a desired neutral position of the sensor. The size of the day zone can be arbitrarily determined by the system designer.

For example, the system designer may set the controller to regard the dead zone as a dead zone within ± 1 mm based on the neutral position in the case of the first detector that detects the linear movement force. Here, the neutral position means a position at which the first detector does not output any signal or outputs a signal called a reference position, and the neutral position may be determined by a system designer's arbitrary selection. In addition, in the case of the second detection unit that detects the rotational movement force, the system designer may set the controller to regard the dead zone within ± 1 degree (1 °) based on the neutral position. The controller may determine the rotation direction and the rotation speed of at least one of the left wheel and the right wheel by reflecting the set dead zone. In detail, when a movement or rotation within the dead zone occurs, the controller determines that there is no such movement or rotation, and ignores the signal output from the first detection unit or the second detection unit. In other words, the control unit may control the operation of the driving unit only when the linear movement force or the rotary movement force detected by the first detection unit or the second detection unit exceeds a predetermined range.

According to the rotation direction and speed of the wheel determined by the controller, a current is applied to the driving unit, and the driving unit is driven according to the applied current (s54). According to the driving of the driving unit, at least one of the left wheel and the right wheel rotates in a predetermined direction and a predetermined speed.

If feedback is required (Yes in S55), the feedback signal is transmitted to the controller, and the controller may adjust the operation of the driver by transmitting a control signal for resetting the operation of the driver according to the feedback signal (S56).

If the feedback situation is not necessary (NO in s55), the driving unit is driven according to the signal transmitted from the control unit, and at least one of the left wheel and the right wheel rotates according to the driving of the driving unit.

Hereinafter, a method of controlling the operation of a cleaner according to a second embodiment of the present invention will be described.

First, when the cleaner starts driving (S57), and the user cleans using the cleaner, the user may detect that an obstacle exists in the cleaner moving direction, and thus may manipulate the input unit (S58). The input unit may be implemented by a physical button or a touch pad provided on the top or bottom surface of the handle unit described with reference to FIGS. 50A and 50B.

Then, the controller may transmit a control signal to the driver to reduce the rotational speed of the wheel according to the manipulation of the input unit. If necessary, the controller may block the current applied to the driver (S59). In this case, the wheel may stop rotating.

According to the change of the operation of the wheel as described above, the operation of the cleaner may also be changed (S60). In detail, since the rotation speed of the wheel is reduced or the rotation of the wheel is stopped, the cleaner may move less even when the same force is applied.

Hereinafter, a method of controlling an operation of a cleaner according to a third embodiment of the present invention will be described.

First, after the cleaner starts driving by the user (s61), an electrical signal may be continuously output for at least one of the first detector and the second detector (for example, s62). Here, the first detection unit 23 may include the above-described movement detection sensor, and the second detection unit 24 may include the above-described rotation detection sensor.

If the electrical signal is continuously output from the at least one of the first detection unit and the second detection unit for a predetermined time, the controller determines that the handle is broken or malfunctions and cuts off the current applied to the driving unit. The operation may be blocked (s63). The predetermined time may be arbitrarily determined by the system designer. The predetermined time may be arbitrarily selected by the system designer, for example between 0.5 seconds and 2 seconds.

The controller determines that the cleaner does not cause a malfunction when the signals output from the first detector and the second detector are output only within a predetermined time, for example, when the signals are output only within 0.5 seconds, and maintains the current operation of the cleaner. Can be (s64).

If the electrical signal is continuously output from at least one of the first detector and the second detector for a predetermined time so that the controller blocks the operation of the driver, the output of the electrical signal is interrupted or new electrical is generated from the first detector and the second detector. When the signal is output (YES in s65), the operation of the drive unit of the cleaner can be resumed. In this case, the controller may control the operation of the cleaner driver according to the electrical signals previously output from the first detector and the second detector, and operate the cleaner driver according to the new electrical signals output from the first detector and the second detector. It may also be controlled (s66).

If there is no change in the electrical signal (NO in s65), the control unit may maintain the standby state of operation of the driving unit (S67).

Hereinafter, a method of controlling the operation of a cleaner according to a fourth embodiment of the present invention will be described.

54 is a flowchart illustrating a fourth embodiment of a method of controlling an operation of a cleaner.

The controller may determine whether the state of the cleaner is being charged (S68). Here, the cleaner may be a wireless cleaner using a storage battery as a power source.

If the state of the cleaner is being charged, the controller stops controlling the cleaner operation according to the user's application of force (s69). In other words, if the state of the cleaner is being charged, the controller may ignore any electrical signal input from the first and second detectors.

In this case, if the state of the cleaner is not being charged, the controller may control the operation of the cleaner by controlling the operation of the driver according to the applied force of the user sensed by the first and second detectors (S70).

Hereinafter, a method of controlling an operation of a cleaner according to a fifth embodiment of the present invention will be described.

55 is a flowchart of a fifth embodiment of a method of controlling an operation of a cleaner.

When the cleaner is driven (s71), a cruise function may be used according to a user's selection (s72). The cruise function means that the cleaner is controlled to move at a constant speed according to a user's selection or a predefined setting.

When an obstacle is detected on the moving path by the obstacle detecting sensor while the cruise function is used, the controller may stop the operation of the driving unit by blocking a current applied to the driving unit. Accordingly, when an obstacle exists on the moving path, the cleaner may be prevented from colliding with the obstacle.

If the obstacle is not detected, the operation of the cleaner may be maintained (s74).

Meanwhile, if the cruise function is not used, the operation of the cleaner may be maintained regardless of the cruise function (s76).

Hereinafter, a method of controlling the operation of a cleaner according to a sixth embodiment of the present invention will be described.

Referring to FIG. 56, the state detection sensor may detect an inclination of the cleaner body and transmit a detection result to the controller (S77). Here, the inclination of the main body means the degree of inclination of the main body from the normal of the reference plane, and the reference plane may include a ground surface or a bottom surface of the cleaning tool assembly 1420.

The controller determines whether the inclination is less than or greater than the first critical angle. (S78) If the inclination is less than the first critical angle, the controller determines that the main body is standing perpendicular to or perpendicular to the ground, and the cleaner is not in use. It may be determined that (s79). Here, the first threshold may be arbitrarily selected by the system designer. For example, the first threshold may be 30 degrees.

On the contrary, if the inclination is greater than the first critical angle, it may be determined that the main body is inclined to some extent, and accordingly, it may be determined that the cleaner is currently in use (s80).

The state detection sensor detects the tilt of the cleaner body (S81). As described above, the inclination of the main body means the degree of inclination of the main body from the normal of the reference plane, and the reference plane may include a ground surface or a bottom surface of the cleaning tool assembly 1420.

The controller determines whether the inclination is less than or greater than the second critical angle (s82). If the inclination is greater than the second critical angle, the controller determines that the cleaner is lying on the ground and lying down (s83), and the inclination is the second critical angle. If smaller, the cleaner is erected at an angle, so it may be determined that the cleaner is in use (s84). Here, the second critical angle may be arbitrarily selected by the system designer. For example, the second critical angle can be any value between 80 degrees and 90 degrees.

On the other hand, if it is determined that the cleaner is lying, the control unit ignores the transmitted electric signal even if at least one of the first detection unit and the second detection unit (s85), the wheel according to the abnormal operation of the handle unit This rotation can be prevented (s86).
