  A general self-propelled cleaning device detects a detection signal transmitted from the charging device when the capacity or operating time of electricity reaches a predetermined value, and the charging process is performed back. A device used for reversing charging induction of this type of self-propelled cleaning device generally transmits one or a plurality of induction signals from the horizontal direction of the main body, and the self-propelled cleaning device detects a transmission signal from the charging device. Thus, the position of the charging device is determined, and the charging device is turned back to charge.

  The prior art charging device employs a method in which a signal is transmitted horizontally, detected by a self-propelled cleaning device, and guided back. However, regardless of the type of inductive signal on the charger, whether it is infrared, ultrasonic or laser beam, the resulting signal is limited by furniture and ornaments placed around the charger, limiting the signal coverage. It is done. Furthermore, in order for ordinary people to consider the space and aesthetics, it is often found that the charging device is attached to the corner of the room. For this reason, the signal is shielded by the place element or furniture of the place, so that the self-propelled cleaning device cannot effectively detect, the detection time of the induction signal by the self-propelled cleaning device becomes long, and the limited work time The disadvantage of reducing the efficiency remains.

  Therefore, an object of the present invention is to provide a self-propelled cleaning device reversing charge induction method that can shorten the signal detection time by the self-propelled cleaning device and improve the efficiency of the limited working time. To do.

  Another object of the present invention is to provide a self-propelled cleaning device reversing charging induction facility that can shorten the signal detection time by the self-propelled cleaning device and the self-propelled cleaning device improves the efficiency of limited work time. To do.

  In accordance with the object of the present invention, the self-propelled cleaning device reversing charging induction method transmits a first detection signal from the first detection signal source to the moving traveling surface of the self-propelled cleaning device from above the self-propelled cleaning device. And means for moving the self-propelled cleaning device toward the first detection signal source after the first signal detection unit of the self-propelled cleaning device receives the first signal detection signal.

  In accordance with the object of the present invention, another self-propelled cleaning device recharging method is the first self-propelled cleaning device after the first signal detection unit receives the first detection signal. When the means for moving toward the detection signal source and the self-propelled cleaning device are moving toward the first detection signal source, the second signal detection unit of the self-propelled cleaning device is moved from the second detection signal source. Means for moving toward the second detection signal source after receiving the second detection signal to be transmitted.

  In accordance with another object of the present invention, a self-propelled cleaning device pull-back charging facility is provided with a first detection signal source, a charging device for transmitting the first detection signal, and a first detection signal for detecting the first detection signal. An apparatus main body provided with a first signal detection unit. The first signal detection unit receives the first detection signal transmitted from the upper side of the device body to the moving travel surface of the device body, and then moves to the first detection signal source.

  In accordance with another object of the present invention, a self-propelled cleaning device reversing charging facility is provided with a first detection signal source and a second detection signal source, and transmits a first detection signal and a second detection signal, respectively. An apparatus main body provided with a device, a first signal detection unit for detecting a first detection signal, and a second signal detection unit for detecting a second detection signal. The first signal detection unit receives the first detection signal transmitted from the upper side of the device main body to the moving traveling surface of the device main body, and then moves to the first detection signal source, and the second signal detection unit performs the second detection signal. After moving to the second detection signal source.

  The method and the equipment of the embodiment of the present invention mainly transmit the first detection signal from the charging device to one reflecting surface in the room, diffract it on the traveling surface on which the device main body moves, When one detection signal area is formed and the apparatus main body enters the first detection signal area, it is moved in the direction of the first detection signal source according to the intensity of the first detection signal. On the other hand, since the second detection signal is transmitted from the horizontal direction toward the charging device toward the first detection signal after being diffracted, the second detection signal is detected while the device main body moves forward toward the first detection signal source. And moved toward the second detection signal source. Furthermore, the first detection signal after diffraction is transmitted toward the upper side of the device main body, transmitted toward the upper side of the device main body, and received by the first detection signal unit attached to the uppermost surface of the device main body. The first detection signal can avoid interference of obstacles such as furniture installed on the running surface, and the first detection signal after diffraction is wide in range, so that the device body makes the first detection signal relatively simple. Then, the device main body is guided by the second detection signal in a narrower range, and is electrically connected to the charging device.

  Please refer to FIG. 1 and FIG. The recharging method according to the embodiment of the present invention can be realized by the following method, for example.

  The charging device 1 includes a first signal transmission source 11 provided obliquely above the charging device 1, a second signal transmission source 12 provided at the tip of the charging device 1, and a conductive material provided with positive and negative electrodes to output electricity. A unit 13 and an outlet 14 connected to a DC power source are included.

  The device main body 2 includes a drive mechanism 21 that drives and moves the device main body 2 by drive wheels 211 attached to both sides of the device main body 2, and a main cleaning brush 221 and side cleaning brush 222 having hair, or any one of them. A cleaning mechanism 22 that performs floor surface cleaning by one or a suction port that only has a dust suction function, a dust collection mechanism 23 that collects dust cleaned by the cleaning mechanism 22, and a calculation or determination of various data, 2, a control unit 24 that controls various functions, a charging unit 25 that contacts and electrically connects the conductive unit 13 of the charging device 1, a first signal detection unit 26 that is provided on the uppermost surface of the device body 2, and the device body 2. And a second signal detection unit 27 provided on the side surface of

  The first signal detection unit 26 attaches a plurality of first signal detection elements 261 to the center of the uppermost surface of the device body 2 at regular intervals such as in the circumferential direction, and the second signal detection unit 27 includes a plurality of second signal detection units 27. The signal detection elements 271 are attached to the peripheral portion on the front side of the device body 2 at equal intervals.

  Still referring to FIG. A transmission source such as an infrared ray, an ultrasonic wave, or a laser beam is generated from the first signal transmission source 11, and the first detection signal 111 is transmitted from the charging device 1 upward to the reflection surface 3. The reflection surface 3 is, for example, a surface that is not the traveling surface 4 of the device main body 2 such as a ceiling or a wall, and the first detection signal 111 is diffracted by the reflection surface 3 to the traveling surface 4 where the device main body 2 moves from the reflection surface 3. The second signal transmission source 12 generates a transmission source such as an infrared ray, an ultrasonic wave, or a laser beam, and the second detection signal 121 is transmitted from the horizontal direction of the charging device 1 toward the first detection signal 111 after diffraction. As a result, the first detection signal 111 and the second detection signal 121 are partially overlapped, and the first detection signal 111 and the second detection signal 121 have different signal frequencies.

  Continuing to refer to FIG. 3 and FIG. In the present embodiment, the first detection signal 111 after diffraction is formed on the traveling surface 4 of the device main body 2 in the first detection signal area 112 having a wide range. After the device main body 2 performs a cleaning operation for a certain time or when the electric capacity of the internal battery falls to a predetermined value, the first signal detection unit 26 on the uppermost surface of the device main body 2 detects the first detection signal 111. Be started. Then, after the device main body 2 enters the first detection signal area 112, the first signal detection element 261 attached to the first signal detection unit 26 detects the first detection signal 111. Since the first signal detection elements 261 are installed at different positions, the control unit 24 determines whether the first signal transmission source 11 is based on the intensity received by the first signal detection element 261 of each of the first signal detection units 26. After determining the direction and distance to the device body 2, the device body 2 is moved toward the position of the first signal transmission source 11. When the device main body 2 is moving toward the first signal transmission source 11, the second signal detection unit 27 installed on the front side of the device main body 2 starts to detect the second detection signal 121 and displays the second detection signal 121. When detected, the device main body 2 moves in the direction of the second signal transmission source 12 and stops moving after being electrically connected to the charging unit 25 of the device main body 2 and the conductive unit 13 of the charging device 1.

  When the embodiment of the present invention is carried out, instead of providing the second signal transmission source 12 for transmitting the second detection signal 121, the first detection signal 111 after diffraction is directly used to connect the device main body 2 to the charging device. 1 can be charged by charging.

  The method and the equipment of the embodiment of the present invention mainly transmits the first detection signal 111 from the charging device 1 to the one reflecting surface 3 in the room, diffracts the traveling surface 4 on which the device body 2 moves, and travels. When the first detection signal area 112 having a large range is formed on the surface 4 and the device main body 2 enters the first detection signal area 112, the direction of the first detection signal source 11 depends on the intensity of the first detection signal 111. Moved to. On the other hand, since the second detection signal 121 is transmitted from the horizontal direction toward the charging device 1 to the first detection signal 111 after diffraction, the second detection signal 121 is detected during the process in which the device body 2 moves forward toward the first detection signal source 11. The signal 121 is detected and moved toward the second detection signal source 12. Further, the first detection signal 111 after the diffraction is transmitted toward the upper side of the device main body 2 and received by the first detection signal unit on the uppermost surface of the device main body 2. The main body 2 can detect the first detection signal 111 relatively easily, since the first detection signal after diffraction can be covered with a wide range. The direction and distance of the first detection signal source 11 are clearly grasped, and the device main body 2 is guided by the second detection signal 121 in a narrower range to be electrically connected to the charging device 1. Thereby, the time for the device main body 2 of the self-propelled cleaning device to detect the detection signal can be shortened, and the efficiency of the operation time in which the device main body 2 is limited can be improved.
