20220000326
This application claims priority under 35 U.S.C. §119 to Korean Application No. 10-2020-0080836 filed on Jul. 1, 2020, whose entire disclosure(s) is/are hereby incorporated by reference.
The present invention relates to a control device for remotely controlling a robot cleaner, and more particularly, to a control device for a robot cleaner that provides a function and a user interface (UI) for enhancing user convenience.
A robot cleaner is a household robot that autonomously drives on a surface to be cleaned with a certain area and removes dust or foreign substances around it, and according to its function, it is generally classified into a suction-type robot cleaner that sucks dust by vacuum, and a wet-type robot cleaner with a web mop function that wipes the surface to be cleaned using a mop.
On the other hand, the wet robot cleaner (hereinafter referred to as “robot cleaner”) having the wet mop function has a water container, and it is configured to supply the water contained in the water container to the mop, and to wipe a floor surface with the moisture mop, thereby effectively removing foreign substance strongly attached to the floor surface.
Such a robot cleaner may be controlled using a button provided on the robot cleaner body, or may be remotely controlled by a user terminal, and the like.
However, in a case in which the robot cleaner is controlled using the button provided on the robot cleaner body, it is not practically easy to mount various control functions on the robot cleaner body. Thus, very limited operations such as only on-off control of starting and pausing of cleaning, returning to a charging station, and the like is possible, and there is a problem that remote control is not possible.
In addition, in a case of remotely controlling through a user terminal, conventionally only a limited user interface is provided, so there is a problem that detailed set values of main functions related to the cleaning operation of the robot cleaner cannot be directly input from a user.
Korean Patent Registration No. 10-1352518 discloses a remote control system of a mobile robot configured to include a mobile robot that receives a control signal, performs a charging command included in the control signal, and transmits a response signal to the control signal, and a terminal device that generates the control signal corresponding to the charging command and transmits it to the mobile robot, and generates and displays a control screen based on the response signal.
However, the screen of the terminal device disclosed in Korean Patent Registration No. 10-1352518, is configured to remotely control only limited functions of patrol, cleaning, and charging operations, and there is a problem that the user cannot directly input detailed settings of the mobile robot.
Korean Patent Registration No. 10-2021827 discloses a cleaner that includes a body, a mop module, and a pump, and is configured to perform autonomous driving while mopping and control the pump of the cleaner to change an amount of the water supplied to the mop module.
However, as the pump control of Korean Patent Registration No. 10-2021827 is performed by the control unit of the cleaner, there is a problem that the amount of water supplied to the mop module cannot be directly input from the user.
Korean Patent Registration No. 10-0619753 discloses a robot cleaner that includes a remote control means that converts call information data for calling the location of the robot cleaner into wireless call information data and transmits it when a call means is pressed by a user. The robot cleaner stays in power saving mode if the residual voltage of a battery drops below a certain voltage during cleaning, receives call information data wirelessly from the remote control means, analyzes the received call information data, and selects and outputs a melody for announcing the location according to the analysis result.
However, the remote control means disclosed in Korean Patent Registration No. 10-0619753 is a remote control that does not have a screen, which is a display means. Thus, there is a problem of not providing an interface through which the user can directly input detailed settings of the robot cleaner or an interface that displays information received from the robot cleaner for checking.

Referring to
Hereinafter, the arrangement structure of the main screen 1000 displayed by the process S2000 of
Here, a user means a subject who wants to remotely control the robot cleaner 1 using the control device 5.
Here, the main screen 1000 may be a screen that is first displayed by the control unit 580 when the application stored in the control device 5 is initially executed.
Alternatively, when the application is an application for controlling a plurality of household devices including the robot cleaner 1, the main screen 1000 may be the screen displayed when the user selects the robot cleaner 1 among the plurality of household devices on a separate initial screen by a user's touch screen.
That is, the main screen 1000 means a first control screen displayed in relation to the control of the robot cleaner 1 when the application is initially executed.
The main screen 1000 may receive a control signal for controlling the robot cleaner 1 from the user as a touch input, and for this purpose, the main screen 1000 may have one or more divided areas.
For example, the main screen 1000 may include a first area Al, a second area A2, and a third area A3.
The first area Al may be located in the upper area of the main screen 1000, and a status bar area Al in which a current date/time information, connected communication network information, the battery information of the control device, and the like are displayed and a title area A02 in which name information of a control object (for example, “wet mop robot cleaner”) is displayed may be located on the upper portion of the first area A1.
The control unit 580 arranges and displays a status display module 1100 indicating the current operation status of the robot cleaner 1 in the first area Al of the main screen 1000.
The control unit 580 arranges and displays a user set module 1200 that receives a set value for controlling the robot cleaner 1 through the user's touch input in the second area A2 of the main screen 1000.
In this case, the set value for controlling the robot cleaner 1 means a value of a parameter that is related to the cleaning operation of the robot cleaner 1, and may be changed by the user.
The second area A2 is located lower than the first area A1 and is approximately located in the lower area of the main screen 1000. Preferably, the second area A2 is arranged below the center in the longitudinal direction of the display unit 551 so that the user's touch input can be easily performed.
The third area A3 is located between the first area Al and the second area A2.
The control unit 580 arranges and displays an operation performing module 1300 for operating the robot cleaner 1 through the user's touch input in the third area A3 of the main screen 1000.
On the other hand, when the user remotely controls the robot cleaner 1 using the control device 5, it is common to perform a touch input using a finger while supporting the lowermost edge of the control device 5 with a palm.
That is, while the control device 5 is in use, the first area Al is the area farthest from the area where the user can easily perform touch input without moving the support point in which the user supports the control device 5 with the palm of the hand, and the second area A2 becomes an area closest to the area in which the touch input can be easily performed.
Accordingly, in the control device 5 according to an embodiment of the present invention, the module that does not require editing by the user, that is, the status display module 1100 that does not need to receive the user's touch input is arranged in the first area A1, and the user set module 1200 that needs to directly input the set values for controlling the robot cleaner 1 from the user is arranged in the second area A2, so that a user interface with high useability can be provided.
Hereinafter, the status display module 1100, the user set module 1200, and the operation performing module 1300 arranged in each area of the main screen 1000 will be described in more detail.
The status display module 1100 may include at least one of a cleaning mode display unit 1110, a reservation status display unit 1130, and a progress time display unit 1120.
Referring to

Here, when the cleaning status is displayed, the information on the cleaning mode (for example, deep cleaning, zigzag cleaning, or intensive cleaning) having a preset driving type of the robot cleaner 1 may be displayed together.
At the lower right of the device icon, the icons corresponding to one or more currently set functions of the robot cleaner 1 including the cleaning mode may be displayed. For example, the set function may include whether to mute, the cleaning mode described above, a set water supply amount, whether to set interlocking cleaning, a camera connection state, and a remaining battery charge, and the like.
Next, the total time during which the robot cleaner 1 have performed the cleaning operation may be displayed on the progress time display unit 1120. The total time that the cleaning operation has been performed is the time from when the robot cleaner 1 leaves the charging station and starts the cleaning operation to the current point in time during which the cleaning operation has been performed, and may be displayed in the order of hours, minutes, and seconds.
Next, the reservation information of some functions of the robot cleaner 1 may be displayed on the reservation status display unit 1130. In this case, as the reservation information, the names of some reserved functions and whether the functions are reserved (ON or OFF) may be displayed in text. In addition, some of the functions may be displayed on the reservation status display unit 1130 only when reserved and not displayed when not reserved.
Hereinafter, the operation performing module 1300 arranged in the third area A3 of the main screen 1000 will be described.
The user set module 1200 arranged in the second area A2 of the main screen 1000 will be described after the operation performing module 1300 is first described.
Referring to
The monitoring operation unit 1310 includes a preset icon and text, and when the monitoring operation unit 1310 is selected by the user's touch input, the control unit 580 transmits a control signal to the robot cleaner 1 to start the operation of monitoring a room.
Here, the room monitoring operation may be, for example, the operation for transmitting to the control device 5 a photographing screen in which an area in which a motion is detected is photographed several times through an image photographing means provided in the robot cleaner 1, when a motion is detected in the room. In this case, the image photographing means may be, for example, a camera provided in front of the body 50 of the robot cleaner 1.
When the photographing screen is transmitted to the control device 5, an alarm or vibration sounds in the control device 5, and a user can check the photographing screen through the control device 5.
The cleaning operation unit 1320 includes a preset icon and text, and when the cleaning operation unit 1320 is selected by the user's touch input, the control unit 580 transmits a control signal to the robot cleaner 1 to start the cleaning operation. or to temporarily stop the cleaning operation being performed. For example, when the cleaning operation unit 1320 is selected while the robot cleaner 1 is located on the charging station, the robot cleaner 1 starts the cleaning operation and drives, and when the cleaning operation unit 1320 is selected while the robot cleaner 1 performs the cleaning operation, the robot cleaner 1 temporarily stops the cleaning operation.
The charging operation unit 1330 includes a preset icon and text, and when the charging operation unit 1330 is selected by the user's touch input, the control unit 580 transmits a control signal to the robot cleaner 1 to return to the charging station.
Hereinafter, the user set module 1200 arranged in the second area A2 of the main screen 1000 will be described.
The user set module 1200 may include at least one of a cleaning mode set unit 1210, a cleaning area set unit 1220, an interlocking cleaning set unit 1240, and a repeated cleaning set unit 1250.
When the cleaning mode set unit 1210 is selected by the user's touch input, the cleaning mode (for example, deep cleaning, zigzag cleaning, or intensive cleaning) having a preset driving type is displayed in a drop-down menu form on the main screen 1000, and the user can select one of the cleaning modes.
Next, when the cleaning area set unit 1220 is selected by the user's touch input, the main screen 1000 is switched to a screen for designating an area to perform the cleaning operation on the surface to be cleaned or an area to prohibit the cleaning operation.
Next, when the interlocking cleaning set unit 1240 is selected by the user's touch input, the main screen 1000 is switched to a screen for selecting another robot cleaner to cooperate with the robot cleaner 1 to perform the interlocking cleaning operation.
Here, the interlocking cleaning operation means a cooperative operation that when another robot cleaner (for example, a suction-type robot cleaner) selected by the user's touch input completes the cleaning operation of sucking dust, the robot cleaner 1 performs a wet mop cleaning operation successively.
In this interlocking cleaning operation, when the other selected robot cleaner transmits a cleaning completion signal to the robot cleaner 1 after completion of the cleaning operation, the control unit 110 may be performed to control the robot cleaner 1 to start the cleaning operation.
Next, the repeated cleaning set unit 1250 is to repeat the cleaning operation for a preset number of times in the cleaning mode set by the cleaning mode set unit 1210.
Hereinafter, the process S3000 of
The user set module 1200 includes a water supply set unit 1230 that receives a set value of target water supply amount to be supplied to the mops 30 and 40 by the water supply unit 140 of the robot cleaner 1 from the user.
First, the control unit 580 receives the user's touch input for setting the target water supply amount to be supplied to the mops 30 and 40 on the water supply set unit 1230 through the display unit 551 (S3110).
In this case, referring to
In this case, the image object 1235 may have a water droplet shape as shown in
In addition, the water droplet-shaped image object 1235 is formed so that the inside of the image object 1235 is filled with shadows according to the set water supply amount, and through this, the user can intuitively grasp the degree of the set water supply amount. For example, the image object 1235 filled with 0% shading corresponds to the “dry mop” mode, which is a mode in which the water supply amount is 0. As the target point 1233 on the slider 1231 moves from left to right, the shadow of the image object 1235 is gradually filled in, and the water supply mode is changed to correspond from “low wet mop” mode to “high wet mop” mode.
In addition, a mode display item 1239 in which the set water supply amount mode is displayed in text may be arranged on the upper side of the slider 1231. For example, at the same time as the target point 1233 moves on the slider 1231, the text of the mode display item 1239 may be changed to “dry mop”, “low wet mop” or “high wet mop” in real time and displayed.
In addition, a first slider area 1231a from a preset point on the slider 1231 to the right end point of the slider 1231 corresponding to the maximum water supply amount may be displayed in a first color. In this case, the preset point may be a point where the water supply amount corresponds to the “high wet mop” mode.
The second slider area 1231b, which is another point on the slider 1231 other than the point marked with the first color, may be displayed with a second color to be distinguishable from the point marked with the first color.
Due to this, the user can intuitively grasp the appropriate range of the water supply amount to be supplied to the mops 30, 40.
On the other hand, the target point 1233 may be slid left and right on the slider 1231 by the user's touch input, and the water supply amount corresponding to the point where the target point 1233 stops on the slider 1231 may be set as a set value of the target water supply amount to be supplied to the robot cleaner 1.
In this case, the user's touch input for moving the location of the target point 1233 is performed by touching down the target point 1233 and then dragging it to a desired location, or by tapping directly at the desired location and locating the target point 1233.
In addition, a third color may be displayed from the left end of the slider 1231 to the target point 1233 set by the user's touch input, and accordingly, the user can intuitively grasp the water supply amount set by himself or herself.
In addition, when the target point 1233 slid by the user is located between the preset point and the point corresponding to the maximum water supply amount, that is, when the target point 1233 is located in the first slider area 1231a, the entire color of the slider 1231 is converted to the first color, and a warning message 1237 may be displayed at the bottom of the slider 1231.
For example, the warning message 1237 may be a message saying “Please be careful for excessively wet wet mop.”
Accordingly, when the set value of the target water supply amount is excessively set, there is an effect of drawing attention to the user through a warning message 1237, and it is possible to prevent in advance a phenomenon in which water flows to the floor surface, which is the surface to be cleaned, due to excessive wetness of the mops 30 and 40 coupled to the robot cleaner 1.
On the other hand, in order to increase the efficiency of mop cleaning, it is preferable to set the target water supply amount differently according to the degree of contamination of the floor surface whenever the robot cleaner 1 starts a new cleaning operation. That is, setting the target water supply amount is a main function of the robot cleaner 1 including the wet mop function, and the user's accessibility to this function must be high.
In the control device 5 according to an embodiment of the present invention, the water supply set unit 1230 is arranged on the main screen 1000, so that the user can set the set value of the target water supply amount with minimal touch input after the application is executed.
Also, preferably, the water supply set unit 1230 may be arranged relatively on the upper portion of the second area A2 of the main screen 1000.
Accordingly, the control device 5 according to an embodiment of the present invention provides the effect of increasing the convenience of the user's sliding operation for setting the target water supply amount.
Meanwhile, when the set value of the target water supply amount is set by the user's touch input, the control unit 580 transmits a control signal corresponding to the information on the set value of the target water supply amount to the robot cleaner 1 (S3120).
In this case, the control signal may be a control signal for controlling the water pump 143 of the robot cleaner 1. More specifically, the control signal for the water pump 143 that is transmitted from the control unit 580 to the robot cleaner 1 through the wireless communication unit 510 is received by the communication unit 160 of the robot cleaner 1, and the control unit 110 of the robot cleaner 1 may control the water supply amount supplied to the mops 30 and 40 in a manner that varies the driving time of the motor for operating the water pump 143 of the robot cleaner 1.
For example, as the driving time of the water pump 143 increases, the water supply amount supplied from the water container 141 of the robot cleaner 1 to the first mop 30 and the second mop 40 through the water supply tube 142 increases. As the driving time of the water pump 143 becomes shorter, the water supply amount supplied from the water container 141 of the robot cleaner to the first mop 30 and the second mop 40 through the water supply tube 142 is reduced.
Conventionally, a robot cleaner having a wet mop function cannot be remotely controlled or only a limited user interface is provided even when a remote control device is provided. Therefore, in the conventional art, there is a problem that the user cannot arbitrarily change the water supply amount supplied to the mop of the robot cleaner.
However, since the control device 5 according to an embodiment of the present invention includes the water supply set unit 1230 as a user interface, the water supply amount supplied to the mop of the robot cleaner 1 can be directly set by the user input.
Specifically, the user may set the set value of the target water supply amount as an appropriate set value according to the state of the surface to be cleaned (for example, the area, roughness, contamination level, etc. of the floor surface).
Meanwhile, the user set module 1200 may further include a fall prevention sensitivity set unit 1260 that may receive a set value of the cliff height of the robot cleaner 1 from the user.
First, when the user's touch input selecting the fall prevention sensitivity set unit 1260 arranged on the main screen 1000 is received through the display unit 551 (S3210), the control unit 580 displays on the main screen 1000 a preset set value of cliff height (S3220).
Here, the preset set value of cliff height may be displayed on the main screen 1000 in the form of a drop-down menu by the user's touch input selecting the fall prevention sensitivity set unit 1260.
In this case, the set value of cliff height may be selected from two or more preset set values.
For example, as shown in
In this case, the cliff detection sensor may include at least one of the first lower sensor 123, the second lower sensor 124, and the third lower sensor 125.
Meanwhile, when the drop-down menu 1261 is expanded, a message explaining the cliff height set value may be displayed in each of the items 1261a and 1261b.
For example, as shown in
In addition, in the “sensitive” mode item 1261b, a message “a fall is prevented when the difference in height of the floor is 15 mm or more” may be displayed.
In addition, a default value of the set value of cliff height may be set to a height corresponding to the “basic” mode item.
Meanwhile, the control unit 580 receives the user's touch input selecting the set value of cliff height through the display unit 551 (S3230).
When one set value of cliff height is selected by the user's touch input, the drop-down menu 1261 is rolled up and disappears, and in the fall prevention sensitivity set unit 1260, the mode corresponding to the set value of cliff height selected by the user can be displayed as text. (Refer to
Next, the control unit 580 transmits a control signal corresponding to the information on the set value of cliff height selected by the user to the robot cleaner 1 (S3240).
More specifically, the control signal corresponding to the information on the selected set value of cliff height transmitted by the control unit 580 to the robot cleaner 1 through the wireless communication unit 510 is received by the communication unit 160 of the robot cleaner 1, the control unit 110 of the robot cleaner 1 may control the sensitivity of the first lower sensor 123, the second lower sensor 124, and the third lower sensor 125 of the robot cleaner 1.
In this case, the sensitivity can be controlled in such a way that a cliff is determined to be detected when the distance between each sensing detected by the first lower sensor 123, the second lower sensor 124 and the third lower sensor 125 and the floor surface B is higher than the set value of cliff height selected by the user.
When the cliff is detected, the control unit 110 of the robot cleaner 1 controls the first actuator 56 and the second actuator 57 to control the driving of the robot cleaner 1 to avoid the cliff.
Conventionally, since the set value of cliff height for detecting a specific cliff is pre-stored in the robot cleaner as one predetermined value, when the robot cleaner is driving on the floor surface where there is a step lower than the predetermined set value of cliff height, there is a problem in that the step is not recognized as a cliff and a situation of falling is occurred.
On the other hand, in the case of the conventional suction-type robot cleaner, it is possible to re-climb using wheels even if the robot cleaner falls from a low step that is not recognized as a cliff because it travels using the wheels. Since the robot cleaner 1 to be controlled by the control device 5 of the present invention drives by the rotation of the first mop 30 and the second mop 40, there is a problem that it cannot climb again by itself once it falls even with a low step.
However, since the control device 5 according to an embodiment of the present invention includes the fall prevention sensitivity set unit 1260 as a user interface, the cliff height detected by the robot cleaner 1 can be set by the user input.
Specifically, the user may appropriately change the set value of the cliff height according to the condition of the floor surface (for example, a situation in which a cleaning is performed on
Docket No. HP-0025 a thin baby mat, etc.).
In addition, in the control device 5 according to an embodiment of the present invention, the fall prevention sensitivity set unit 1260 is arranged so that the set value of cliff height can be directly selected on the main screen 1000 by the user's touch input, it provides the effect that the set value of cliff height can be set with a minimal touch input from the user after the application is executed.
Meanwhile, the user set module 1200 may further include a location detection unit 1280 for searching for a current location of the robot cleaner 1.
First, when receiving the user's touch input selecting the location detection unit 1280 arranged on the main screen 1000 (S3310), the control unit 580 switches the main screen 1000 to a cleaner search screen 2100. (S3320).
In this case, as shown in
For example, in the message display area 1282, a message “If a cleaner search button is pressed, a notification sound sounds from the cleaner” may be displayed to guide the corresponding function.
Next, the control unit 580 receives the user's touch input selecting the cleaner search button 1281 on the cleaner search screen 2100 (S3330).
When the cleaner search button 1281 is selected, the control unit 580 may send a signal to the robot cleaner 1 to inquire about a location where the robot cleaner 1 stops driving. In addition, a control signal may be transmitted so that an alarm sounds on the display unit 170 of the robot cleaner 1 while inquiring about the location of the robot cleaner 1.
Finally, the control unit 580 receives the location where the robot cleaner 1 stops driving, and displays the location where the driving stopped on the cleaner search screen 2100 as the current location of the robot cleaner 1 as an image (S3340).
In this case, the current location of the robot cleaner 1 is displayed on the image display area 1283.
Here, the current location of the robot cleaner 1 may be displayed as an image indicating, together with a map of the surface to be cleaned recognized while the robot cleaner 1 drives, the relative location of the robot cleaner 1 with respect to the map.
Meanwhile, the current location of the robot cleaner 1 is displayed as the image on the control device 5 and at the same time, an alarm is transmitted from the display unit 170 of the robot cleaner 1. Specifically, the alarm may be transmitted from the voice transmitting means 172 of the robot cleaner 1.
Accordingly, the user may recognize the location of the robot cleaner 1 from the image displayed on the cleaner search screen 2100, or recognize the location of the robot cleaner 1 by listening to the alarm sent through the display unit 170 of the robot cleaner 1.
A conventional suction-type robot cleaner generates noise in the process of sucking dust, so that the current location of the robot cleaner can be easily recognized, but since the robot cleaner dedicated to the wet mop function has relatively little noise, it is difficult for the user to recognize which area of the surface to be cleaned is currently driven.
Accordingly, when the robot cleaner 1 stops driving due to an error or an obstacle while driving, there is a problem in that the user cannot easily search for the location of the robot cleaner 1.
However, since the control device 5 according to an embodiment of the present invention includes the location detection unit 1280 as a user interface, even when the robot cleaner 1 stops while driving, the user can easily detect the current location of the robot cleaner 1 by performing the touch input remotely.
Meanwhile, the user set module 1200 may further include a cleaning reservation set unit 1270 that can reserve the cleaning operation of the robot cleaner 1.
Referring to
Here, as shown in
In addition, each of the cleaning operation list 1271 may include a button for activating or deactivating a reserved cleaning operation. In this case, when there is no reserved cleaning operation, the cleaning operation list 1271 is not displayed.
Next, when receiving the user's touch input selecting the reservation adding button 1272 or the cleaning operation list 1271 on the reservation list screen 3100 (S3430), the control unit 580 switches the reservation list screen 3100 to a reservation set screen 3200 that can set a wet mode of the mops 30 and 40 coupled to the robot cleaner 1 (S3440).
In this case, when the reservation adding button 1272 is selected, a reservation setting for a new cleaning operation can be selected on the reservation set screen 3200, and when one cleaning operation list among the cleaning operation list 1271 is selected, the preset setting of the corresponding cleaning operation may be changed.
In addition, the reservation set screen 3200 may be configured to select a time, a day of the week, and a cleaning area to perform the cleaning operation.
On the other hand, the reservation set screen 3200 includes a mop wet button 1273 that can activate or deactivate the wet mode.
According to the present invention, by displaying the mop wet button 1273 on the reservation set screen 3200, the user can set the wet mode to quickly wet the mops 30, 40 installed on the robot cleaner 1 while reserving the time, day, and cleaning area to perform the cleaning operation.
Next, when receiving the user's touch input activating the mop wet button 1273 on the reservation set screen 3200 (S3450), the control unit 580 transmits a control signal for reserving the wet mode to the robot cleaner 1 (S3460).
When the robot cleaner 1 performs the reserved cleaning operation and the wet mode is set to the currently performed reserved cleaning operation, the control unit 110 of the robot cleaner 1 can control the water pump 143 so that the water pump 143 is driven to supply to the mops 30, 40 with more water amount than a preset water supply amount, if the moisture content of the mops 30 and 40 is less than a target moisture content.
In this case, the preset water supply amount may be the water supply amount set by the user. In addition, the target moisture content refers to a moisture content corresponding to the preset water supply amount. Here, the moisture content corresponding to the water supply amount may be stored in the memory 180 as a table.
Meanwhile, the moisture content of the mops 30 and 40 may be calculated by the control unit 110 of the robot cleaner 1 receiving the motor current value of the water pump. For example, the greater the moisture content of the mops 30 and 40, the greater the load is applied to the motor of the water pump 143 connected to the mops 30 and 40, and it is measured a large value of the motor current of the water pump 143.
When the cleaning operation is reserved and executed, the mops 30 and 40 must be coupled to the robot cleaner 1 in advance, and in this case, the state is usually that the mops 30 and 40 are dry or have insufficient moisture content to perform wet mop cleaning. Therefore, it takes a long time from the start of the cleaning operation until the time in which the mops 30 and 40 have a moisture content suitable for performing wet mop cleaning, and the cleaning efficiency of the robot cleaner 1 decreases.
However, since the control device 5 according to an embodiment of the present invention includes the cleaning reservation set unit 1270 that can select the wet mode as a user interface, it can be set to quickly increase the moisture content of the mops 30 and 40 coupled to the robot cleaner 1 when the robot cleaner 1 starts the cleaning operation by the user's input, and thus provides the effect of increasing user convenience in controlling the robot cleaner 1.
Meanwhile, referring to
Accordingly, the user can intuitively check which cleaning operation in the cleaning operation list has the wet mode added, and can select and set the wet mode according to the cleaning operation list.
Meanwhile, referring again to
Here, the overflow menu button 1400 means a button for showing functions and menu items not displayed in a main action, and when the overflow menu button 1400 is selected by the user's touch input, a plurality of menus is listed and displayed.
The overflow menu button 1400 may be arranged along with other action buttons on the right side of the title area A02 in which name information of a control target is arranged.
In this case, the other action buttons may include a home view button 1500 and a cleaning diary button 1600.
The home view button 1500 is for switching to a screen in which an image of the room can be checked in real time through the image photographing device provided in the robot cleaner 1 during the cleaning operation of the robot cleaner 1.
A cleaning diary button 1600 is for switching to a screen that can check the area, cleaning time and cleaning mode that has been cleaned by the robot cleaner 1 by date and time.
Meanwhile, when the overflow menu button 1400 is selected by the user's touch input, a displayed menu list 1400a may include a residual water removal menu 1410.
Referring to
Next, when receiving the user's touch input selecting the residual water removal menu 1410 (S3530), the control unit 580 switches the main screen 1000 to the residual water removal screen for removing the residual water inside the robot cleaner 1 (S3540).
In this case, a residual water removal start button 1411 is displayed on the residual water removal screen 4100 to receive a control signal for switching the robot cleaner 1 to the residual water removal mode.
In addition, an image area 1413 and an explanation area 1412 for explaining a method of removing residual water of the robot cleaner 1 in the residual water removal mode may be displayed on the residual water removal screen 4100.
A guide message guiding a method of removing residual water may be displayed in the explanation area 1412 so that the user can easily remove residual water. In addition, in the explanation area 1412, a warning message to warn that water may splash while the residual water of the robot cleaner 1 is discharged, and at the same time, to call the user's attention to execute the residual water removal mode at a suitable place to remove the residual water may be displayed.
In addition, an image showing a residual water removal method may be displayed on the image area 1413, in order to guide the use while assisting the guide message on the explanation area 1412.
According to the guide message and warning message of the explanation area 1412 and the image of the image area 1413, the user may be guided to move to a suitable place to remove residual water, and may be guided to take a correct posture for removing residual water. Therefore, the user's convenience is improved through this.
Thereafter, when the residual water removal start button 1411 is selected by the user's touch input (S3550), the control unit 580 transmits to the robot cleaner 1 the control signal for switching the robot cleaner 1 to the residual water removal mode capable of discharging the residual water inside the robot cleaner 1 (S3560).
In this case, the residual water removal mode is a mode in which the residual water inside the robot cleaner 1 can be discharged through the water supply tube 142 whenever a pressing operation is applied to the bumper 58 of the robot cleaner 1.
Whether or not the pressing operation is applied to the bumper 58 may be determined by the first sensor 121. In a state in which the robot cleaner 1 is switched to the residual water removal mode, if the first sensor 121 detects a pressing operation of the bumper 58 and transmits a signal, the control unit 110 of the robot cleaner 1 drives the water pump 143 and controls to discharge the water inside the robot cleaner 1 through the water supply tube 142.
On the other hand, when the residual water removal start button 1411 is selected, the robot cleaner 1 is switched to the residual water removal mode and at the same time the control unit 580 may display a residual water removal end button 1414 on the main screen 1000 while switching the residual water removal screen 4100 to the main screen 1000.
The residual water removal mode continues until the residual water removal end button 1414 is selected by the user's touch input, and when the user selects the residual water removal end button 1414, the control unit 580 generates a control signal for releasing the residual water removal mode and transmits it to the robot cleaner 1. When the residual water removal mode is released, the water pump 143 returns to a non-operation state even if the pressing operation of the bumper 58 is detected.
After the residual water removal end button 1414 is selected and the residual water removal mode is released, an end message 1415 notifying the end of residual water removal may be displayed on the main screen 1000. Through this, the user may be informed that the residual water removal mode is released.
In the robot cleaner 1, the liquid remaining in the water container 141 and the water supply tube 142 may exist even after cleaning is completed. In this case, if the cleaning operation is not performed for a long time with liquid remaining in the water container 141 or the water supply tube 142 and the robot cleaner 1 is left unattended, the water supply tube 142 may become contaminated and cause odor.
Conventionally, in order to remove the residual water in the water container of the robot cleaner having a wet mop function, a method in which the user directly separates the water container from the robot cleaner and removes it has been used.
However, since it is limited to the water container 141 that can be separated from the robot cleaner 1, in the above method, there is a problem in that the liquid remaining in the water supply tube 142 that is accommodated inside the body 50 of the robot cleaner 1 and cannot be separated by the user cannot be removed. In addition, since it is impossible to separate the water supply tube 142, there is a problem that cleaning is impossible even if it is contaminated.
However, since the control device 5 according to an embodiment of the present invention has the residual water removal menu 1410 as a user interface, an operation of removing the residual water inside the robot cleaner 1 by the user's input can be performed.
Specifically, the user can select the residual water removal mode to discharge all the residual water of the water supply tube 142, so that the robot cleaner 1 can be hygienically managed.
Meanwhile, when the overflow menu button 1400 is selected by the user's touch input, the set menu 1420 may be displayed on the displayed menu list 1400a.
Referring to
Next, when the control unit 580 receives the user's touch input selecting the set menu 1420 (S3630), the control unit 580 switches the main screen 1000 to a product management screen 5100 including a brightness adjustment menu 1417 (S3640).
Here, the product management screen may include a menu that is not directly related to the cleaning operation of the robot cleaner 1, but for setting auxiliary functions for convenient management of a product (for example, a robot cleaner), for example, a network-related set menu, a menu for setting a nickname of the robot cleaner, a set menu for power saving mode, a consent set menu for camera use, and the like, in addition to the brightness adjustment menu 1411.
On the other hand, when the control unit 580 receives the user's touch input selecting the brightness adjustment menu 1411 (S3650), the product management screen 5100 is switched to the brightness adjustment screen 5200 that displays a plurality of preset set values of brightness 1271 that can be selected by the user (S3660).
Here, a plurality of preset set values of brightness 1271 may be displayed as values indicating the illuminance of the display unit 170 as a ratio, such as “25%, 50%, 75%, and 100%” as shown in
In addition, the default set value of the brightness of the control device 5 may be 100%.
Next, when receiving the user's touch input selecting one brightness among the plurality set values of brightness 1271, the control unit 580 transmits a control signal corresponding to the information on the selected set value of brightness to the robot cleaner 1 (S3670).
In this case, as illustrated in
While being charged in a charging station, light is illuminated from the display means 171 of the display unit 170 provided on the body 50 of the robot cleaner 1. For example, the light may be an LED light indicating a current battery level, reservation information, cleaning mode, etc., and since conventionally it is not possible to adjust the brightness of such an LED light, there is a problem that the user feels uncomfortable because the brightness of the LED light is brighter in the middle of the night than during the day.
However, since the control device 5 according to an embodiment of the present invention has the brightness adjustment menu 1411 as a user interface, the brightness of the display unit 170 of the robot cleaner 1 can be set by the user input, and, it is possible to solve the above-mentioned inconvenience.
In addition, it is possible to reduce power consumption by appropriately selecting the brightness of the display unit 170 of the robot cleaner 1.
In addition, as described above, the brightness adjustment of the display unit 170 of the robot cleaner 1 is independent of the cleaning operation of the robot cleaner 1, but is an auxiliary function set for the convenience of the user.
A user interface with high user convenience can be provided by arranging the menu for selecting such an auxiliary function to be accessible through the set menu 1420 displayed by the overflow menu button 1400 without arranging it on the main screen 1000.
Referring to
Next, when the control unit 580 receives the user's touch input selecting the set menu 1420 (S3730), the main screen 1000 is switched to the product management screen 5100 including a notification sound set menu 1421. switch (S3740).
Here, the product management screen 5100 may include a menu that is not directly related to the cleaning operation of the robot cleaner 1, but is a menu capable of setting auxiliary functions for convenient management of the product (for example, robot cleaner), for example, a network-related set menu, a menu for setting a nickname of the robot cleaner, a set menu for power saving mode, or a consent set menu for camera use, in addition to the notification sound set menu 1421.
On the other hand, when the control unit 580 receives the user's touch input selecting the notification sound set menu 1421 (S3750), the control unit 580 switches the product management screen 5100 to a notification sound adjustment screen 6200 including the volume adjustment menu 1422 (S3760).
In this case, as shown in
On the other hand, when the control unit 580 receives the user's touch input selecting the volume adjustment menu 1422 (S3770), the notification sound adjustment screen 6200 is switched to the volume adjustment screen 6300 that displays a plurality of preset set values of volume level 1423 from which the user can select (S3780).
Here, as shown in
Also, the default of the set value of volume level may be “large”.
Lastly, when receiving the user's touch input selecting any one set value of volume level among the plurality set values of volume level, the control unit 580 transmits a control signal corresponding to the information on the selected set value of volume level to the robot cleaner 1 (S3790).
In this case, according to the control signal transmitted to the robot cleaner 1, the control unit 110 of the robot cleaner 1 may control the volume level of the sound transmitted from the voice transmitting means 172 of the display unit 170.
Meanwhile, as shown in
Unlike the conventional suction-type robot cleaner, the robot cleaner having a wet mop function has a feature of low noise when performing the cleaning operation. Accordingly, the user may feel uncomfortable because the notification sound of the robot cleaner is relatively loud.
However, since the control device according to an embodiment of the present invention includes the volume level adjustment menu 1422 as a user interface, it is possible to set the volume level of the robot cleaner by the user's input, and thus, the user's inconvenience as described above can be solved.
On the other hand, the notification sound to which the set value of volume level selected by the user is applied may be configured to exclude a warning sound due to an error while the robot cleaner 1 is driving.
Accordingly, it is possible to provide an effect of not missing an error warning of the robot cleaner 1 even when the user sets the set value of volume level to be small.
In addition, as described above, the volume level adjustment of the robot cleaner 1 is independent of the cleaning operation of the robot cleaner 1, but is an auxiliary function set for user convenience.
The menu for setting these auxiliary functions is not arranged on the main screen 1000, but is arranged to be accessible through the set menu 1420 displayed by the overflow menu button 1400, so that the user interface with high user convenience can be provided.
As described above, the control device according to an embodiment of the present invention may increase user convenience by providing various user interfaces through which a set value for controlling the robot cleaner may be input.
Specifically, since the control device according to the present invention includes the water supply set unit as a user interface, it is possible to set the water supply amount to be supplied to the mop of the robot cleaner by the user input, thereby increasing user convenience in controlling the robot cleaner.
In addition, since the control device according to the present invention includes the fall prevention sensitivity set unit as a user interface, it is possible to set the cliff height detected by the robot cleaner by the user input, thereby increasing user convenience in controlling the robot cleaner.
In addition, since the control device according to the present invention includes the location detection unit as a user interface, when the robot cleaner stops while driving, the user can easily detect the current location of the robot cleaner, thereby improving user convenience in controlling the robot cleaner.
In addition, since the control device according to the present invention includes the cleaning reservation set unit that can reserve the wet mop mode as a user interface, the moisture content of the mop coupled to the robot cleaner at the time the robot cleaner starts the cleaning operation can be quickly increased by the user's input, and thus user convenience in controlling the robot cleaner can be increased.
In addition, since the control device according to the present invention includes the residual water removal menu as a user interface, it is possible to perform an operation to remove the residual water of the robot cleaner by the user input, thereby increasing user convenience in controlling the robot cleaner.
In addition, since the control device according to the present invention includes the brightness adjustment menu as a user interface, it is possible to set the brightness of the display unit of the robot cleaner by the user input, thereby increasing user convenience in controlling the robot cleaner.
In addition, since the control device according to the present invention includes the volume level adjustment menu as a user interface, it is possible to set the volume level of the display unit of the robot cleaner by the user input, thereby increasing user convenience in controlling the robot cleaner.
