The electric blower 4 generates a flow of air that sucks dust. The electric blower 4 communicates with the suction unit 3 via the dust collection unit 5, and collects dust sucked from the suction unit 3 by the electric blower 4 into the dust collection unit 5. It is configured to

  The power supply unit 6 includes a battery pack 7 containing a plurality of rechargeable secondary batteries, and supplies power to the electric blower 4 and a drive motor 8 described below. The distance measuring sensor (sensor) 9 irradiates light (infrared rays) and measures a distance at an angle between the irradiation light of reflected light reflected by an obstacle such as furniture. A plurality is provided on each of the side and the rear. The level difference sensor (sensor) 10 detects the level difference of the surface to be cleaned (floor surface), and is configured in the same manner as the distance measuring sensor 9 described above, and as shown in FIG. It is provided obliquely downward.

  The rollers 11 are for driving the cleaner main body 1 and are provided on the left and right sides of the cleaner main body 1, and are independently driven left and right by a drive motor 8 mounted on a metal chassis 12, as shown in FIG. The drive motor 8 is constituted by a geared motor having a built-in reduction gear (not shown). The casters 13 support the cleaner body 1 so that it can run freely.

  The panel switch 14 has a function of displaying characters and the like, and has a function of turning on and off when touched, and is provided on the upper surface of the cleaner body 1. The first display means 15 displays a detection state of the distance measuring sensor 9 and the level difference sensor 10, and is configured by a light emitting diode, and is provided above the level difference sensor 10 provided at a corner of the cleaner body 1. . The second display means 16 displays the operating state of the electric blower 4, the drive motor 8, and the like, and is provided on the upper surface of the cleaner body 1. The third display means 17 displays when the cleaner main body 1 is stopped, and is provided on the upper surface of the cleaner main body 1.

  It should be noted that either one of the first display means 15 and the second display means 16 displays a detection state by the distance measuring sensor 9 and the level difference sensor 10 and an operation state of the electric blower 4, the drive motor 8, and the like. It may be. Further, the first display means 15 may be provided on the upper surface of the cleaner body 1.

  The panel switch 14, the first display means 15, the second display means 16, and the third display means 17 are connected to a control device 18. When the user touches the panel switch 14, the control device 18 Controls the operation of the electric blower 4, the drive motor 8 and the like to automatically drive by the rollers 11 driven by the drive motor 8 while sucking dust by the electric blower 4; Is configured to stop at least the drive motor 8 by touching a predetermined part of the drive motor 8. Reference numeral 19 denotes a power switch.

  The cleaner main body 1 includes a suction unit 3, an electric blower 4, a dust collection unit 5, a power supply unit 6, a drive motor 8, a distance measuring sensor 9, a level difference sensor 10, a control device 18, and the like. ing. For this reason, the distance measuring sensor 9 and the step sensor 10 transmit and receive light (infrared rays) through the outer shell 20, and the step sensor 10 is provided obliquely downward at the corner of the cleaner body 1. Light (infrared rays) is transmitted and received through the protruding part 21 having a part protruding. Note that the outer shell 20 may be made translucent.

  A bumper 22 made of an elastic body is provided below the outer shell 20. The handle portion 23 is provided on the upper surface of the cleaner body 1 so as to be able to be pulled out and carries the cleaner body 1.

  The power supply unit 6 is provided behind the roller 11 so that the center of gravity G of the cleaner body 1 is located between the caster 13 and the roller 11 as shown in FIG. For this reason, when the cleaner main body 1 is suspended by the handle 23, the suction unit 3 is tilted so as to be above the roller 11, and when installed on the floor from this state, the suction unit 3 is placed on the floor after the roller 11. So that it abuts.

  The operation of the above configuration will be described. When the power switch 19 is turned on, when starting cleaning, the panel switch 14 sequentially displays whether there is no heat source, whether the door is closed, whether a child or pet is in the room, and so on. Eliminate obstacles. Thereafter, when "start cleaning" is displayed and "OK" is input, the electric blower 4 is driven, the roller 11 is driven by the drive motor 8, and the vehicle starts straight traveling forward. At this time, "cleaning" and "pause" are displayed on the panel switch 14, as shown in FIG.

  While traveling, the distance measuring sensor 9 constantly transmits and receives light (infrared rays) through the transparent or translucent outer shell 20 while performing dust collection work by the electric blower 4, and measures the distance to obstacles such as surrounding furniture. While measuring, the level difference sensor 10 confirms the level difference of the surface to be cleaned in the same manner. The detection state by the distance measuring sensor 9 and the step sensor 10 is displayed by the first display means 15, and the operation state of the electric blower 4, the drive motor 8 and the like are displayed by the second display means 16.

  When the distance from the cleaner main body 1 to an obstacle such as furniture approaches a predetermined distance, the vehicle temporarily stops and then changes its direction by turning a predetermined angle to travel. The same is true when there is a step on the surface to be cleaned. As described above, cleaning is performed by automatically traveling in the cleaning area while avoiding obstacles such as furniture and steps.

  At this time, the exhaust of the electric blower 4 passes between the battery packs 7 as shown by arrows in FIG. 7 so that the exhaust of the electric blower hits the battery pack 7 to cool the battery pack 7. And the temperature rise of the battery can be reduced.

  In addition, since the exhaust of the electric blower 4 is discharged from between the bumper 22 and the cleaner main body 1 as shown by an arrow in FIG. 8, the bumper 22 is provided over almost the entire circumference of the cleaner main body 1. The exhaust of the electric blower 4 can be dispersed and discharged over almost the entire circumference of the cleaner main body 1, the flow velocity at the time of discharge can be reduced, and furniture and the like near the traveling path of the cleaner main body 1 can be discharged. However, the adverse effect of the exhaust can be eliminated.

  Note that the exhaust of the electric blower 4 may be exhausted from the upper surface of the cleaner main body 1 as shown by an arrow in FIG. 9, and in this case, furniture or the like near the traveling path of the cleaner main body 1 may be used. In contrast, the exhaust of the electric blower does not hit, and the adverse effect of the exhaust can be eliminated.

  Next, in a case where an obstacle occurs in the automatic traveling, such as when the vehicle hits an obstacle during traveling, if the user touches the “pause” displayed on the panel switch 14, at least the drive motor 8 is stopped, and Safety can be ensured. At this time, the display of the panel switch 14 is set to “restart”. At this time, since the cleaner main body 1 is stopped, the stop of the cleaner main body 1 can be displayed by the third display means 17 and the position of the cleaner main body 1 can be notified.

  After removing obstacles to the automatic running, when the panel switch 14 touches “OK” displayed at the same time as “restart”, the driving motor 8 drives the roller 11 again to automatically drive the vehicle. Is restarted and the surface to be cleaned is cleaned.

  As described above, the main body of the vacuum cleaner makes the outer shell 20 transparent or translucent, and includes the distance measuring sensor 9 and the step sensor 10 for optically detecting the distance, the heat source, and the like. The transmission and reception of light (infrared rays) of the level difference sensor 10 can be performed through the outer shell 20, the sensor can be reliably operated, the vehicle can run while avoiding obstacles and the like, and the running performance can be improved. . In addition, the structure of the outer shell 20 can be simplified and the cost can be reduced.

  In addition, in order to detect the level difference of the surface to be cleaned (floor surface), it is necessary to provide the level difference sensor 10 obliquely downward, but by arranging it at a corner portion viewed from the upper surface of the cleaner body 1, It can be provided by effectively utilizing the space.

  Further, since the power supply unit 6 is provided behind the roller 11 so that the center of gravity of the cleaner body 1 is located between the caster 13 and the roller 11, when the cleaner body 1 is carried by the handle 23, When the vacuum cleaner main body 1 is installed on the floor from a state of being suspended by the handle 23, the suction force is not applied to the suction part 3 by the roller 11 contacting the floor first, and the suction part 3 is damaged. Can be prevented.

  As shown in FIG. 10, the electric blower 4, the drive motor 8, the distance measuring sensor 9, the level difference sensor 10, and the control device 18 are each connected to a ground wire 24, and the ground wire 24 constitutes the power supply unit 6. It is connected to the negative terminal of the battery 25.

  The operation of the above configuration will be described. When the electric blower 4 is driven and the roller 11 is driven by the drive motor 8 to automatically run and perform cleaning, particularly when the surface to be cleaned is a carpet, static electricity is generated. This static electricity connects the electric blower 4, the drive motor 8, the distance measuring sensor 9, the level difference sensor 10, and the control device 18 to the minus terminal of the battery 25 via the ground wire 24, and therefore, via the ground wire 24. It can escape and prevent destruction by static electricity. In addition, even when a strong electric field is applied, the breakdown due to the strong electric field can be similarly prevented.

  As shown in FIG. 11, the electric blower 4, the drive motor 8, the distance measuring sensor 9, the level difference sensor 10, and the control device 18 are connected to a metal chassis 12 to which the drive motor 8 is attached via a ground wire 24. By connecting the chassis 12 to the minus terminal of the battery 25, similarly, when static electricity or a strong electric field is applied, destruction by the static electricity or the strong electric field can be prevented.

  In this embodiment, the electric blower 4, the drive motor 8, the distance measuring sensor 9, the level difference sensor 10, and the control device 18 are connected to the minus terminal of the battery 25 via the ground wire 24. At least one may be connected to the negative terminal of the battery 25 via the ground wire 24, and the same effect can be obtained.

  As shown in FIG. 12, the dust collecting unit 5 (AA line) shown in FIG. 2 includes a dust box 26 that can be taken out and a filter 27 that is mounted in the dust box 26 and filters dust. The dust box 26 is attached directly above the suction unit 3 so that the dust box 26 can be taken out from a portion other than the front surface of the cleaner body, for example, as shown in FIG. Here, at least one of the dust box 26 and the filter 27 is flame-retarded.

  Also, as shown in FIG. 14, a dust box detection switch 28 is provided on the cleaner body 1 to detect the presence or absence of the dust box 26. As shown in FIG. 28 is turned off, and at least the electric blower 4 is stopped.

  The operation of the above configuration will be described. When the dust box 26 equipped with the filter 27 is stored in the cleaner body 1, the dust box detection switch 28 is turned on. In this state, when the electric blower 4 is driven to suck dust on the surface to be cleaned from the suction unit 3, the dust is filtered by the filter 27 and collected in the dust box 26.

  When the dust collected in the dust box 26 is full, the dust box 26 is taken out and the accumulated dust is discarded. Here, since the dust box 26 can be taken out from a lateral direction other than the front surface of the cleaner body 1, even if the cleaner body 1 starts running while the dust box 26 is being taken out, the dust box 26 can be taken out. The safety can be improved without hitting the person who is taking out the garbage.

  Further, since the dust box 26 is mounted directly above the suction section 3, a hose (not shown) connecting between the dust box 26 and the suction section 3 can be shortened, and the structure can be simplified, and the dust box 26 can be formed easily. It can be easily taken out.

  In addition, when the dust box 26 is not attached, at least the electric blower 4 is stopped by the dust box detection switch 28. Therefore, when the dust box 26 is not attached, dust is not sucked in, and it can be kept clean. .

  In addition, since at least one of the dust box 26 and the filter 27 is subjected to flame retardancy, safety can be ensured even when high-temperature dust such as a lit cigarette is inhaled.

  As shown in FIG. 16, a metal chassis 12 is provided with a drive motor 8 for driving a roller 11 for running the cleaner body 1, and the cleaner body 1 is mounted above the chassis 12. A spring 29 that constantly urges the cleaner body 1 upward is provided between the cleaner body 1 and the cleaner body 1.

  As shown in FIG. 17, when the weight of the cleaner main body 1 is applied to the cleaner body 1 by a weight equal to or more than a predetermined value, the weight detector switch 30 lowers the cleaner body 1 against the spring force of the spring 29, and When the weight detection switch 30 is turned on, at least the drive motor 8 is stopped. Other configurations are the same as those in the first embodiment.

  The operation of the above configuration will be described. When a weight greater than or equal to a predetermined value is applied to the cleaner main body 1 such as when a person rides on the cleaner main body 1, the weight detection switch 30 is turned on to stop at least the drive motor 8 to perform cleaning. A person riding on the machine body 1 can be notified of the abnormal state, and safety can be ensured.

  Also, since the cleaner body 1 is mounted above the chassis 12 via the spring 29, the spring 29 functions as a damper, and the vibration or impact when the cleaner body 1 is run by the rollers 11 is reduced. The reliability can be improved without being transmitted to the main body 1, especially the control device.

  In addition, as shown in FIG. 18, the bumper 22a is provided below the cleaner body 1 and is made of an elastic body to prevent the furniture from being damaged and to be movable when it comes into contact with an obstacle such as furniture. A control device (not shown) is provided for controlling the operation of the electric blower, the drive motor, and the like by the movement of the bumper 22a when the bumper 22a comes into contact with an obstacle such as furniture.

  Here, the bumper 22a is disposed at a position at least 10 mm away from the floor surface (the surface to be cleaned) and 100 mm or less from the floor surface. Other configurations are the same as those in the first embodiment.

  The operation of the above configuration will be described. When the electric blower 4 is driven and the roller 11 is driven by the drive motor 8 to automatically travel and perform cleaning, and when there is an obstacle at a position 10 mm or more from the floor, the obstacle hits the bumper 22a. Thus, the electric blower, the drive motor, and the like are stopped by the control device.

  On the other hand, when the floor surface (the surface to be cleaned) is a carpet, it may be necessary to prevent the electric blower, the drive motor, and the like from stopping when the carpet hits the bumper 22a. By arranging the carpets at a distance as described above, it is possible to prevent the operation of the carpet from being affected.

  Further, a switch such as a stove placed on the floor (cleaning surface) is located at a position higher than the floor by 100 mm. Therefore, even if the bumper 22a hits a stove or the like during traveling, the switch is not turned on by the bumper 22a, and safety can be ensured.

  As shown in FIG. 19, the suction unit 3 a is provided with the rotating brush 2 so as to be rotatable, and when the brushed cloth 32 is fixed before and after the rotating brush 2 and hits the floor surface (cleaning surface), In addition to preventing the floor from being damaged, a raised fabric 33 is provided to improve suction performance. A step detecting switch 34 for detecting a step on the floor is provided near both ends of the suction section 3a. As shown in FIG. 20, the step detecting switch 34 has a rotatable first roller body 35 which comes into contact with the floor surface.

  The first roller body 35 is indicated by a solid line in FIG. 21C when in contact with the floor surface, and is indicated by a dotted line in FIG. The state shown in FIG. As shown in FIG. 21A, a protrusion 36 is provided on the first roller body 35, and when the first roller body 35 is in contact with the surface to be cleaned, suction is performed. The detection switch 37 provided in the section 3a is turned on, and when a wheel is removed due to a step or the like, the detection switch 37 is turned off, and at least the drive motor is stopped.

  Further, as shown in FIG. 21C, a magnet 39 is fixed to the roller portion 38 on the first roller body 35, and a magnetic sensing element 40 such as a Hall element is located at a position where the magnetic flux of the magnet 39 can be detected. The magnetic detecting element 40 is configured to detect the rotation state of the roller unit 38, in other words, the running state of the cleaner body.

  The operation of the above configuration will be described. In a state where the first roller body 35 of the step detecting switch 34 provided near both ends of the suction part 3a is in contact with the surface to be cleaned, the electric blower is driven and the rotary brush 2 is driven at the same time, and the roller is driven by the drive motor. Drives and automatically runs to clean.

  In this state, when the first roller body 35 comes off the concave step, the state shown by the dotted line in FIG. 21C is reached, the detection switch 37 is turned off, at least the drive motor is stopped, and the cleaner is turned off. It is possible to prevent the main body from falling on the concave step.

  Further, in a state in which the roller is driven by the driving motor and the roller is automatically traveling, the roller portion 38 of the first roller body 35 is rotating. Output a good signal. Here, when the roller that automatically travels through the cleaner body slips, the cleaner body does not travel despite the rotation of the drive motor and the roller.

  At this time, since the roller portion 38 of the first roller body 35 stops, there is no output from the magnetic detection element 40, and it is possible to detect that the cleaner main body is stopped. It is possible to eliminate the problem that the vacuum cleaner does not run despite the rotation.

  Further, as shown in FIG. 22, the suction portion 3b is provided with a safety switch 41 having a sliding portion substantially at the front center. As shown in FIG. 23, the safety switch 41 has a rotatable second roller body 42 that comes into contact with the floor surface (the surface to be cleaned).

  The second roller body 42 has the same configuration as the first roller body 35 of the sixth embodiment. When the second roller body 42 is in contact with the floor, the second roller body 42 is in a state shown by a solid line in FIG. When the main body of the vacuum cleaner is tilted and the suction part 3b is separated from the floor surface, a state shown by a dotted line in FIG. 21C is obtained. In this state, at least the rotary brush 3 is stopped.

  The operation of the above configuration will be described. In a state where the second roller body 42 of the safety switch 41 provided substantially at the center of the front part of the suction part 3b is in contact with the floor surface (the surface to be cleaned), the electric blower is driven and the rotating brush 2 is driven at the same time. The roller is driven by the drive motor to automatically run and perform cleaning.

  In this state, when the main body of the cleaner is tilted and the suction portion 3b is separated from the floor surface, the second roller body 42 is brought into a state shown by a dotted line in FIG. 21C, the detection switch 37 is turned off, and at least the rotating brush is turned off. 2 can be stopped, and the safety in the case of an abnormality such as the vacuum cleaner main body tilting and the suction part being separated from the floor surface can be improved.

  Further, in the state where the rollers are driven by the drive motor and the vehicle is automatically traveling, the roller portion of the second roller body 42 is rotating as in the case of the above-described sixth embodiment. A periodic signal is output to the detection element 40. Here, when the roller that automatically travels through the cleaner body slips, the cleaner body does not travel despite the rotation of the drive motor and the roller.

  At this time, since the roller portion of the second roller body 42 stops, there is no output from the magnetic sensing element 40, and it is possible to detect that the cleaner body is stopped, so that the drive motor and the rollers rotate. Despite this, it is possible to eliminate the problem that the cleaner body does not run.

  The safety switch 41 may also serve as the level difference detection switch 34. In this case, the configuration can be simplified and the cost can be reduced.
