FIG. 5 is a plan view of the operating device 20 shown in FIG. FIG. 6 is a functional block diagram of the electric vacuum cleaner 10. FIG. FIG. 7 is a flowchart showing a flow of operations of the vacuum cleaner 10.

  As shown in FIG. 1, the vacuum cleaner 10 of this embodiment includes a head unit 11, a hollow first pipe part 12a connected to the head part 11, and a hollow first pipe connected to the first pipe part 12a. Two pipe parts 12b and a main body part 13 connected to the second pipe part 12b are provided. The head part 11 and the main body part 13 are connected to each other through pipe lines inside the two pipe parts 12a and 12b. The main body 13 has a drive unit 13a that performs a suction operation, and the vacuum cleaner 10 operates the drive unit 13a to provide dust in the area to be cleaned in the head unit 11. A cleaning operation is performed in which the air is sucked from the suction port and collected in a garbage bag in the main body 13 through the two pipe portions 12a and 12b.

  As shown in FIG. 1, in the middle of the two pipe portions 12a and 12b, a grip portion 14 that is gripped by an operator during cleaning is provided. As shown in FIGS. 1 and 2, the gripping unit 14 is provided with an operation device 20, and the operator operates the operation device 20 to perform suction in the head unit 11. The suction force changes according to the operation amount of the operation unit 23b of the apparatus 20, that is, the push-down amount.

  As shown in FIG. 2, a foreign matter sensor 15 for detecting the amount of foreign matter passing therethrough is provided in the conduit of the second pipe portion 12b. As the foreign matter sensor 15, a device that counts the number of dusts as foreign matter or a device that detects the volume of foreign matter in the space can be used. Information corresponding to the target state can be detected based on the detection result of the foreign matter sensor 15. That is, it is possible to detect the amount of dust and the degree of dirt in the area of the floor F (FIG. 1) where the head unit 11 is placed.

As the foreign matter sensor 15, various types of sensors such as an optical type, an electric resistance type, an electrostatic type, and a magnetic type can be used. For example, an optical foreign matter sensor includes a light emitting element and a light receiving element. Based on the ratio between the intensity of light emitted from the light emitting element and the intensity of light received by the light receiving element, the foreign matter present between both elements Calculate the amount. In addition, in an electric resistance type, electrostatic type, or magnetic type foreign matter sensor, detection is based on a change in electrical resistance, capacitance, or magnetic field that changes according to the amount of foreign matter in a certain area around the sensor. I do.
The foreign matter sensor 15 is not limited to the position shown in FIG. 2 and can be arranged in an arbitrary number at arbitrary positions in the pipe lines of the two pipe portions 12a and 12b. It can also be provided in the head portion 11.

  As shown in FIG. 6, the detection result by the foreign matter sensor 15 is output to a control device 35 as a control unit. In the control device 35, the operation reaction force applied to the operation unit 23 b of the operation device 20 is changed by controlling the drive of the motor 30 in accordance with the detection result given from the foreign matter sensor 15. More specifically, when the amount of foreign matter is less than a predetermined value, the operation reaction force is set to a constant initial value, for example, zero, and when the amount of foreign matter exceeds a predetermined value, an operation reaction larger than the initial value is set. Set the force. Accordingly, since the amount of dust can be transmitted to the operator's finger touching the operation unit 23b, the operator pushes down the operation unit 23b more strongly without visually confirming the suction force. It is possible to intuitively take measures such as increasing

  Further, in addition to changing the operation reaction force in the operation unit 23b in accordance with the amount of foreign matter, the operator is notified that the amount of foreign matter has exceeded a predetermined value by means of vibration, sound, light, etc. Good. It is preferable that these notification means are provided on the surface or the periphery of the operation unit 23b of the operation device 20 because the information is easily transmitted to the operator.

Hereinafter, the controller device 20 will be described in detail.
3 includes a main body frame 22, a moving member 23 slidably supported by the main body frame 22, and a motor 30 supported by the main body frame 22 and applying forward and backward force to the moving member 23. Prepare.

  The main body frame 22 is formed of a metal plate, and is formed by bending side plate portions 22a and 22b and a rear plate portion 22c facing each other into a U-shape. The moving member 23 is made of a synthetic resin material or a lightweight metal material, and has a main body portion 23a and an operation portion 23b that is provided at the tip of the main body portion 23a and that directly contacts the hand or finger of the operator of the vacuum cleaner 10.

Guide protrusions 22d and 22d are provided inside the side plate portions 22a and 22b of the main body frame 22, and guide grooves 23c and 23c are formed on both side surfaces of the main body portion 23a. The guide protrusions 22d and 22d are inserted into the guide grooves 23c and 23c. When the guide grooves 23c and 23c slide with the guide protrusions 22d and 22d, the moving member 23 moves forward along the side plate portions 22a and 22b (see FIG. Y1 direction) and back (Y2 direction) can be reciprocated along a linear trajectory.

  A pinion shaft 29 is rotatably supported on the side plate portions 22 a and 22 b of the main body frame 22, and the pinion gear 24 is fixed to the pinion shaft 29 so that it can rotate together. A rack 23d is integrally formed on the upper surface of the main body 23a, and the teeth of the rack 23d are arranged in the front-rear direction (Y1-Y2 direction). The pinion gear 24 is always meshed with the rack 23d.

A motor 30 is fixed to the outside of the side plate portion 22 a, and an output gear 26 is fixed to the output shaft of the motor 30. A reduction gear train 25 is provided inside the side plate portion 22a. The reduction gears 25a and 25b constituting the reduction gear train 25 are respectively formed integrally with a large-diameter gear and a small-diameter gear, and are rotatably supported by a gear shaft fixed to the side plate portion 22a. The output gear 26 meshes with the large-diameter gear of the reduction gear 25a, the small-diameter gear of the reduction gear 25a meshes with the large-diameter gear of the reduction gear 25b, and the small-diameter gear of the reduction gear 25b meshes with the pinion gear 24. Is decelerated and transmitted to the pinion gear 24.
The moving member 23 may not be linearly moved as long as it can move forward and backward. For example, the moving member 23 may move forward and backward along a curved locus.

  As shown in FIGS. 3 and 4, a compression coil spring 27 is provided between the rear plate portion 22 c of the main body frame 22 and the rear end portion of the moving member 23. Due to the urging force of the compression coil spring 27, the meshing backlash between the rack 23d and the pinion gear 24 and the meshing backlash of the reduction gear train 25 are suppressed.

  As shown in FIG. 3, a position detector 28 is provided outside the side plate 22 b of the main body frame 22. The position detection unit 28 includes a detection case 28a fixed to the side plate 22b, a stator unit fixed to the detection case 28a, and a rotor unit 28b that rotates within the detection case 28a. A tip end portion 29 a of the pinion shaft 29 protrudes laterally from a bearing portion formed on the side plate portion 22 b and is fitted to the rotor portion 28 b, and the rotor portion 28 b rotates together with the pinion gear 24 and the pinion shaft 29. To do.

  The position detection unit 28 is a magnetic detection type encoder, a rotating magnet is fixed to the rotor unit 28b, a magnetic detection element such as a GMR element is provided in the stator unit, and the rotation angle of the rotor unit 28b is detected by the magnetic detection element. Is done. The position detection unit 28 may be a resistance change type or optical type encoder.

  In the example shown in FIG. 3, the position detection unit 28 is provided in the power transmission path from the output shaft of the motor 30 to the rack 23 d, but a linear detection type position detection unit is provided between the moving member 23 and the main body frame 22. May be provided.

  It is preferable that the position detection unit 28 can output different values for all the forward and backward strokes of the moving member 23 so that the absolute position of the moving member 23 can be detected. As a result, when the power supply to the controller device 20 is cut off, and when the power is supplied thereafter, it is possible to know at which position in the front-rear direction the moving member 23 is stopped.

  However, an encoder or the like provided in the motor 30 may be used as the position detection unit 28 so that only the relative movement position of the moving member 23 is detected. In this case, when the energization of the controller device 20 is cut off and then energized, a so-called calibration process is performed in which the control is started after the moving member 23 is moved to the reference position in the backward direction or the forward direction. Done.

As shown in FIG. 6, the operating device 20 has a control device 35.
The control device 35 governs the operation of the electric vacuum cleaner 10 and is incorporated in the main body 13 and the grip 14. The control device 35 is composed mainly of a CPU (Central Processing Unit) and a storage unit 35a. When electric power is supplied to the vacuum cleaner 10, the control described below is performed based on a program stored in the storage unit 35a. The control device 35 includes a display unit 36 such as a color liquid crystal panel and a speaker.

The detection output detected by the position detection unit 28 is detected by the position detection circuit 37 and given to the control device 35. In the control device 35, the control signal output to the drive unit 13a of the main body unit 13 is changed according to the amount of the operation unit 23b pushed down in the Y2 direction by the operator as a result of detection by the position detection unit 28. . For example, as the amount of depression of the operation unit 23b by the operator increases, the amplitude of the drive pulse of the drive unit 13a is increased or the drive frequency is shortened, thereby increasing the suction amount in the head unit 11.
Instead of such control, suction may be performed when the pressing amount of the operation unit 23b is equal to or greater than a certain value, and suction may not be performed when the amount is less than the certain value.

  The detection result detected by the foreign matter sensor 15 is output to the control device 35. In the control device 35, a control signal is given to the motor driver 38 so that an operation reaction force corresponding to the amount of foreign matter detected by the foreign matter sensor 15 is presented to the operation unit 23b, and the motor 30 is controlled according to this signal. Is done. For example, the operation reaction force is increased as the amount of foreign matter detected by the foreign matter sensor 15 increases. Thus, the operator can intuitively know the amount of dust in the area to be cleaned with his / her hands and fingers in the operation unit 23b which controls the suction amount. For this reason, it is possible to continue the operation by setting the desired suction amount by an intuitive operation, for example, by changing the push-down amount of the operation unit 23b according to the amount of dust.

  Alternatively, the operation of the drive unit 13a may be stopped when the control device 35 determines that the amount of foreign matter is greater than or equal to a predetermined value based on detection by the foreign matter sensor 15. Thereby, when the inside of a pipe line is clogged with a foreign material, it can avoid performing a forced suction, and can prevent failure of the vacuum cleaner 10.

Next, the operation of the operation device 20 will be described.
In the operating device 20, the moving member 23 can be moved to an arbitrary position by giving a control command from the control device 35 to the motor driver 38 to control the operation of the motor 30. For example, as shown in FIG. 4, the moving member 23 can be stopped at a position advanced in the Y1 direction, and can be stopped at a position retracted in the Y2 direction as shown in FIG. The initial position of the moving member 23 can be set to any position in accordance with the control flow executed by the control device 35.

  For example, when the operating device 20 is stopped, the moving member 23 is moved backward as shown in FIG. 5, and when the power is supplied to the operating device 20, the motor 30 is started and the moving member 23 is moved to FIG. It is possible to move forward to the position shown in FIG. 2 and set that position as the initial position of the operation unit 23b.

  When the moving member 23 is set to the initial position shown in FIG. 4, when the operation unit 23 b is pushed backward (Y2 direction) by a finger or hand, the backward movement of the moving member 23 is detected by the position detection unit 28. The retraction distance is calculated by the position detection circuit 37 and notified to the control device 35. The control device 35 outputs a drive signal corresponding to the retreat distance to the drive unit 13a. Thereby, when the retreat distance is large, a large suction force is generated, and when the retraction distance is small, the suction force is controlled to be small. More specifically, by changing the amplitude, pulse width, frequency, etc. of the pattern of the drive signal, the drive intensity, frequency, etc. of the drive unit 13a are changed, whereby the suction strength by the head unit 11, Change the suction pattern.

  A detection result by the foreign matter sensor 15 is given to the control device 35, and a command for giving an operation reaction force corresponding to the amount of foreign matter indicated by the detection result is notified to the motor driver 38, and the motor 30 operates according to this command. In the control device 35, the magnitude of the operation reaction force is determined according to the amount by which the operation unit 23 b is pushed down by the operator and the amount of foreign matter detected by the foreign matter sensor 15.

Next, with reference to FIG. 7, the flow of operation | movement of the vacuum cleaner 10 is demonstrated.
The electric vacuum cleaner 10 is operated by operating a power switch provided on the main body 13 to start operation. When the operation unit 23b is pressed in this state, suction is started (step S1). The amount by which the operation unit 23 b is pushed down is detected by the position detection circuit 37 based on the detection result by the position detection unit 28 and given to the control device 35.

  The control device 35 generates a drive signal corresponding to the push-down amount detected by the position detection circuit 37 and sequentially outputs the drive signal to the drive unit 13 a of the main body unit 13. The drive unit 13a is driven by a drive signal given from the control device 35. As a result, the target area is cleaned by the electric vacuum cleaner 10 with a suction amount corresponding to the amount of depression of the operation unit 23b (step S2). .

  On the other hand, the detection by the foreign matter sensor 15 also starts with the start of the operation of the electric vacuum cleaner 10, and the detection result is given to the control device 35 every fixed time, for example, 0.1 second. Based on the detection result of the foreign matter sensor 15, the control device 35 determines whether or not foreign matter (garbage) is detected by a predetermined amount or more during the latest unit time, for example, 1 second (step S3).

  When it is determined in the detection result by the foreign matter sensor 15 that the foreign matter is a predetermined amount or more (YES in step S3), the control device 35 changes the drive signal for the motor driver 38 according to the amount of the foreign matter, thereby The operation state of the unit 23b is controlled (step S4). As this control, for example, the motor 30 is driven so that an operation reaction force corresponding to the amount of foreign matter is presented to the operation unit 23b.

  As control of the operation state in step S4, vibration of intensity or frequency corresponding to the amount of foreign matter may be presented to the operation unit 23b. As the vibration presenting means, for example, a piezoelectric body disposed on the surface of the operation unit 23b is used. A drive current is applied to the piezoelectric body from the control device 35, and the intensity and frequency of the vibration to be presented are changed by controlling the amplitude, pulse width, frequency, and the like of the pulse.

  When it is determined in the detection result by the foreign matter sensor 15 that the foreign matter detected during the most recent unit time is less than the predetermined amount (NO in step S3), the control device 35 has enough dust in the target region. Predetermined information that is collected and notifies that the cleaning of the area has been completed is presented to the operation unit 23b (step S5), thereby completing the cleaning of the area (step S6). Examples of the predetermined information presented in step S5 include release of an operation reaction force, an operation reaction force or vibration at a specific frequency.

As described above, the operation of the vacuum cleaner 10 according to the above-described embodiment is controlled in accordance with the operation amount with respect to the operation unit 23b. In addition, the foreign matter sensor 15 detects the state of dust or dirt in the area to be cleaned, and according to the detection result, an operation reaction force is presented to the operation unit 23b to control the operation state. Thereby, since the state of the object is presented on the operation unit 23b, the state of the object can be recognized without depending on vision or hearing, and the work corresponding to the state can be continued intuitively.
In addition, for an area that is difficult to visually recognize, such as a gap in furniture, the state can be grasped by the operation reaction force presented on the operation unit 23b, and an appropriate cleaning operation can be performed.

A modification will be described below.
(1) Instead of the foreign matter sensor 15 or in addition to the foreign matter sensor 15, an atmospheric pressure sensor may be provided in one of the two pipe portions 12a and 12b. Information corresponding to the target state can be detected based on the detection result of the atmospheric pressure sensor. Since the change in the atmospheric pressure in the pipe line corresponds to the amount of dust in the pipe line and the suction port of the head unit 11, the detection result by the barometric sensor indicates that the dust in the area of the floor F on which the head unit 11 is placed. Corresponds to the amount and dirt.

  Various sensors can be used as the atmospheric pressure sensor. For example, in an electrostatic sensor, a change in atmospheric pressure is detected as a change in capacitance by a change in the distance between electrodes facing each other. In addition, an electrical resistance sensor detects an electrical resistance that varies depending on the atmospheric pressure using the piezoelectric effect. Furthermore, in the vibration type sensor, vibration is applied to a thin metal cylinder, and the atmospheric pressure is detected based on the frequency that changes depending on the atmospheric pressure.

  The detection result by the atmospheric pressure sensor is output to the control device 35, and a control signal is given to the motor driver 38 so that the operation reaction force is presented to the operation unit 23b according to the atmospheric pressure in the pipe unit, and the motor 30 is controlled. . For example, the operation reaction force is increased as the amount of foreign matter in the pipe portion increases and the atmospheric pressure decreases. As a result, as in the case of control by the foreign matter sensor 15, the operator can intuitively know the amount of dust in the area to be cleaned with his / her hands and fingers.

(2) A posture sensor for detecting the posture of the vacuum cleaner 10 may be further provided. For example, a gyro sensor is used as the attitude sensor. When the posture sensor is disposed in the first tube portion 12a, the position and orientation of the grip portion 14 can be determined. The force with which the operator grips the grip portion 14 and the force with which the operator presses the operation portion 23b differs depending on the position and orientation of the grip portion. Therefore, if the operation reaction force is controlled according to the detection result by the posture sensor, the force does not depend on the posture. It is possible to ensure a state in which the operator can easily operate.

(3) Although the case where it applied to a vacuum cleaner as an electric appliance of this invention was shown in the said embodiment, this invention is applicable also to electric appliances other than a vacuum cleaner. For example, when applied to a dryer (hair dryer), the basic configuration is the same as that shown in FIG. 6, and the following temperature sensor or the like is used instead of the foreign matter sensor 15. In this dryer, the drive unit 13a sends out winds having different air volumes and temperatures to the operator's hair according to the control of the control device 35. Here, the adjustment of the air volume is performed using the operating device 20 shown in FIGS. 3 to 5 and is controlled so that the air volume increases as the operation unit 23b is pushed in the Y2 direction.

  The dryer includes, for example, a temperature sensor, a humidity sensor, and a distance sensor instead of the foreign matter sensor 15 of FIG. The temperature sensor and the humidity sensor detect the temperature or humidity around the air outlet, and detect the temperature and humidity as the hair state of the target area of the air blowing destination based on the detection result. The distance sensor is a sensor that optically detects the distance between the dryer and the hair in the target region.

The detection result by the temperature sensor and the humidity sensor and the detection result by the distance sensor are given to the control device 35, and the control device 35 detects the state of the hair in the target region more accurately by combining these detection results. be able to. Further, the control device 35 outputs a drive signal corresponding to the hair state to the motor driver 38, whereby the motor 30 is driven, thereby presenting an operation reaction force on the operation unit 23b. For example, when the hair temperature is higher than a predetermined value, for example, 60 ° C or higher, or when the hair humidity is lower than a predetermined value, for example, 20% or lower, or the distance from the hair is lower than a predetermined value, For example, an operation reaction force is presented when the distance is 3 cm or less. Therefore, the operator can know whether the temperature and position of the dryer are appropriate in the operation unit 23b without visual confirmation, and can know the dry state of the hair. It is possible to intuitively cope with changes in the amount of pushing in.
Although the present invention has been described with reference to the above embodiment, the present invention is not limited to the above embodiment, and can be improved or changed within the scope of the purpose of the improvement or the idea of the present invention.

  As described above, the electric appliance according to the present invention is useful in that the state of the target can be recognized and the operation can be intuitively continued according to the state.
