In this embodiment, the main body 110 of the floor cleaning device 100 further includes a dust collection module 113, a track module 114, a power module 115, and a control unit 116. The driving module 111, the wiping module 112, the dust collecting module 113, the track module 114, and the power module 115 are respectively coupled to the control unit 116.

The dust collection module 113 has at least one dust suction motor, a dust suction valve, a dust collecting box, and the like. The dust collection module 113 is configured to perform floor cleaning when the main body 110 moves. In practice, the dust suction module 113 can be disposed at the bottom or the side of the main body 110, but the embodiment is not limited.

The trajectory module 114 can be used to locate and record the cleaning area, the charging area, and the corresponding movement trajectory of the floor cleaning device 110. In detail, the trajectory module 114 can record the movement path trajectory (eg, cleaning route) of the floor cleaning device 100 and the location of the cleaning area. Therefore, after the floor cleaning device 100 is charged, the position of the cleaning area recorded in the track module 114 and/or the movement track can be automatically moved from the charging area to the position of the cleaning area.

In addition, the location of the charging area may be defined by the control unit 116 according to the previously locked unknown location of the charging area in the trajectory module 114, which is not limited in this embodiment. In other words, those skilled in the art having the knowledge of the prior art should be able to infer that the floor cleaning device 100 automatically locates the charging area and moves to the charging area, and therefore will not be described herein.

When the control unit 116 of the floor cleaning device 100 detects that the power module 115 has been charged, the control unit 116 confirms the cleaning area according to the movement track recorded by the track module 114 and/or the position of the cleaning area, and drives the driving. The module 111 moves the body 110 to move the floor cleaning device 100 from the charging area to the cleaning area to continue the floor cleaning operation. For example, the control unit 116 can open at least one of the wiping module 112 and the dust collection module 113 when the floor cleaning device 100 reaches the cleaning area to perform a floor cleaning process. It should be noted that, when the floor cleaning device 100 is moved from the charging area to the cleaning area, the control unit 116 can also turn off the operation of the wiping module 112 and the cleaning module 113 to save power.

Then, the control unit 116 can also control the motor acceleration in the driving module 111 to improve the moving speed of the floor cleaning device 100 and shorten the floor cleaning during the way from the floor cleaning device 100 to the cleaning area and the charging area.

Referring to FIG. 3 and at the same time, FIG. 2 is a schematic flow chart of the steps of the method for saving power of the floor cleaning device according to the first embodiment of the present invention.

First, in step S101, when the floor cleaning device 100 is turned on, the control unit 116 of the floor cleaning device 100 detects whether the power of the power module 115 is lower than a preset value. If the control unit 116 detects that the power of the power module 115 is not lower than a preset value (that is, the power of the power module 115 is higher than a preset value), step S102 is performed. On the other hand, if the control unit 116 detects that the power of the power module 115 is lower than the preset value, step S111 is performed.

In step S102, the control unit 116 can drive the trajectory module 114 to confirm the position of the recorded cleaning area. In step S111, the control unit 116 drives the motor in the driving module 111 to move the body 110 to cause the floor cleaning device 100 to go to the charging area for charging.

Next, in step S112, the control unit 116 determines whether the power module 115 has completed charging. When the control unit 116 determines that the power module 115 has been charged When the power is completed, step S102 is performed to confirm the location of the cleaning area. On the other hand, when the control unit 116 determines that the power module 115 has not been fully charged, it returns to step S112.

Then, if the dust collection module 113 has been activated, the control unit 116 turns off the vacuum motor in step S103 to stop the operation in the dust collection module 113. Control unit 116 may also stop the operation of wipe module 112 to further reduce power consumption.

In step S104, the control unit 116 drives the motor in the driving module 111 to move the body 110 to cause the floor cleaning device 100 to go to the cleaning area. Subsequently, in step S105, the control unit 116 determines whether the floor cleaning device 100 has reached the cleaning area based on the position of the cleaning area recorded in the track module 114 and the route track currently being moved by the floor cleaning device 100. If the control unit 116 determines that the floor cleaning device 100 has reached the cleaning area, step S106 is performed. On the other hand, if the control unit 116 determines that the floor cleaning device 100 has not reached the cleaning area, then returns to step S104 to continue moving the body 110 to advance the floor cleaning device 100 toward the cleaning area.

In step S106, the control unit 116 turns on at least one vacuum motor in the dust collection module 113 to perform vacuuming. Next, in step S107, the floor cleaning device 100 starts the floor cleaning, that is, by starting the vacuum motor, the dust on the floor surface of the assembly floor is started. At the same time, the floor cleaning device 100 can also open the wiping module 112, and after the dust collection module 113 vacuums, wipe the floor.

Then, in step S108, the control unit 116 detects the power state of the power module 115 again, and determines whether the power of the power module 115 is lower than a preset value. When the control unit 116 determines that the power of the power module 115 is lower than the preset value, step S109 is performed. On the other hand, if it is determined that the power of the power module 115 is still higher than the preset value, the process returns to step S107 to continue the line cleaning. Cheng.

In step S109, the control unit 116 drives the trajectory module 114 to record the currently cleaned area and obtain the position corresponding to the cleaning area. Then, in step S110, the control unit 116 turns off the vacuum motor to stop the operation of the dust collection module 113. At the same time, the control unit 116 can also turn off the wiping module 112, thereby saving power. After the control unit 116 closes the vacuum module 112 and/or the wiping module 112, step S111 is executed to drive the motor in the driving module 111 to move the body 110 to cause the floor cleaning device 100 to go to the charging area for charging.

For example, when the local board cleaning device 100 is turned on by the operator, and the control unit 116 of the floor cleaning device 100 determines that the current power of the power module 115 is higher than a preset value, the control unit 116 of the floor cleaning device 100 The track module 114 is controlled to confirm the position of the cleaning area to drive the driving module 111 to move the body 110 to cause the floor cleaning device 100 to go to the position of the cleaning area. During the journey of the floor cleaning device 100 to the cleaning area, the control unit 116 actively closes the wiping module 112 and the dust collection module 113 until reaching the cleaning area. In other words, the control unit 116 automatically opens the wiping module 112 and the dust collection module 113 when the floor cleaning device 100 reaches the cleaning area to perform a corresponding floor cleaning process. When performing the floor cleaning work, the control unit 116 measures the power of the power module 115 at any time, and when the power of the power module 115 is lower than a preset value, the control unit 116 drives the trajectory module 114 to record the position of the current cleaning area. At the same time, the dust control unit 116 and the wiping module 112 are closed. Then, the control unit 116 drives the driving module 111 to move the body 110 to return the floor cleaning device 100 to the charging area for charging.

For another example, when the local board cleaning device 100 is turned on by the operator When the control unit 116 of the floor cleaning device 100 determines that the current power of the power module 115 is lower than a preset value, the control unit 116 of the floor cleaning device 100 drives the driving module 111 to move the body 110 to clean the floor. The device 100 returns to the charging area for charging. When the power module 115 in the floor cleaning device 100 is fully charged, the control unit 116 then controls the trajectory module 114 to confirm the position of the cleaning area to drive the driving module 111 to move the body 110, so that the floor cleaning device 100 can go to the cleaning area. , for the subsequent floor cleaning process.

Accordingly, by actively closing the cleaning function between the charging area and the cleaning area, the cleaning of the wiping module 112 and the cleaning module 113 can effectively reduce the power consumption of the floor cleaning apparatus 100, and extend the operation time of the floor cleaning apparatus 100. The operation and cleaning efficiency of the floor cleaning device 100 is improved.

(Fourth embodiment)

Please refer to FIG. 6. FIG. 6 is a flow chart showing the steps of a method for saving power of a floor cleaning device according to a fourth embodiment of the present invention.

First, in step S401, when the floor cleaning device 100 is turned on, the control unit 116 of the floor cleaning device 100 detects whether the power of the power module 115 is lower than a preset value. If the control unit 116 detects that the power of the power module 115 is not lower than the preset value, step S402 is performed. On the other hand, if the control unit 116 detects that the power of the power module 115 is lower than the preset value, step S412 is performed.

In step S402, the control unit 116 determines that the track module 114 is No route trajectory already exists. More specifically, if the trajectory module 114 has recorded the movement trajectory of the previous floor cleaning device 100, step S403 is performed. If the trajectory module 114 does not have the movement trajectory of the previous floor cleaning device 100, step S406 is performed.

In step S412, the control unit 116 drives the drive module 111 to cause the floor cleaning device 100 to go to the charging area for charging. Next, in step S413, the control unit 116 determines whether the power module 115 has been charged. When the control unit 116 determines that the power module 115 has been charged, step S402 is performed. On the other hand, when the control unit 116 determines that the power module 115 has not been charged, the process returns to step S413.

Then, in step S403, the control unit 116 turns off the vacuum motor to stop the operation of the dust collection module 113. The control unit 116 can also stop the operation of the wiping module 112 at the same time to save power.

In step S404, the control unit 116 drives the motor in the drive module 111 to cause the floor cleaning device 100 to go to the cleaning area. Subsequently, in step S405, the control unit 116 determines whether the floor cleaning device 100 has reached the cleaning area based on the position of the cleaning area recorded in the track module 114 and the current movement of the floor cleaning device 100. If the control unit 116 determines that the floor cleaning device 100 has reached the cleaning area, step S406 is performed. On the other hand, if the control unit 116 determines that the floor cleaning device 100 has not reached the cleaning area, then returns to step S404 to continue moving the floor cleaning device 100.

In step S406, the control unit 116 turns on at least one of the vacuuming motors 113 to perform vacuuming. Next, in step S407, the floor cleaning apparatus 100 starts floor cleaning. Then, in step S408, the control unit 116 detects the power state of the power module 115 again, and determines the power mode. Whether the power of the group 115 is lower than a preset value. When the control unit 116 determines that the power of the power module 115 is lower than the preset value, step S409 is performed. On the other hand, if it is determined that the power of the power module 115 is still higher than the preset value, the process returns to step S407 to continue the floor cleaning process.

In step S409, the control unit 116 drives the trajectory module 114 to record the currently cleaned area and obtain the position corresponding to the cleaning area. Then, in step S410, the control unit 116 turns off the vacuum motor to stop the operation of the dust collection module 113. At the same time, the control unit 116 can also turn off the wiping module 112, thereby saving power. In step S411, the control unit 116 drives the increased motor speed in the drive module 111 to accelerate the moving speed of the body 110, increase the moving speed of the floor cleaning device 100, and execute step S412.

The difference between the power saving method of the floor cleaning device described in FIG. 6 and the power saving method of the floor cleaning device described in FIG. 3 is that the power saving method for the floor cleaning device provided in FIG. 4 has the moving acceleration mechanism described in FIG. 4 and FIG. The trajectory route judgment mechanism. The method for saving the floor cleaning device according to FIG. 6 can determine the position of the cleaning area according to the previously recorded trajectory route, and improve the moving speed of the floor cleaning device 100 between the floor cleaning device 100 and the cleaning area and the charging area. The time required for the board cleaning device 100 to move to the charging area.

In actual implementation, the code of the floor cleaning device power method corresponding to FIG. 6 may be designed on a microcontroller or an embedded controller to execute the method in FIG. 6 by the control unit 116. The method for saving power of the floor cleaning device is described, but the embodiment is not limited. In addition, FIG. 6 is only used to describe a power saving method of the floor cleaning apparatus 100, and thus FIG. 6 is not intended to limit the present invention.

In summary, the embodiment of the present invention provides a floor cleaning device and a power saving method thereof. The floor cleaning device and the power saving method thereof can be moved by the floor cleaning device from the cleaning area to the charging area, or from the charging area to the cleaning area.
