Description

Technology Field

[0001] The present specification relates to a method for providing customized cleaning information, a vacuum cleaner, and a method for controlling the vacuum cleaner. More specifically, it relates to a method for providing customized cleaning information using a vacuum cleaner that performs cleaning by sucking up or wiping away dust or foreign matter from a cleaning target area, the vacuum cleaner, and a method for controlling the vacuum cleaner. Background Technology

[0002] Generally, a vacuum cleaner is a home appliance that uses electricity to suck up air to collect small debris or dust and fill it into a dust bin inside the product, and it is commonly referred to as a vacuum cleaner.

[0003] These vacuum cleaners can be classified into manual vacuum cleaners, which are used for cleaning while the user moves the vacuum cleaner directly, and automatic vacuum cleaners, which are used for cleaning while driving on their own. Manual vacuum cleaners can be classified into canister-type vacuum cleaners, upright vacuum cleaners, handheld vacuum cleaners, stick-type vacuum cleaners, etc., depending on the form of the vacuum cleaner.

[0004] In the past, canister-type vacuum cleaners were widely used for household use, but recently, handheld and stick vacuum cleaners, which offer improved convenience by providing the dust bin and the main body as a single unit, are becoming increasingly popular.

[0005] Canister-type vacuum cleaners have the main body and the suction nozzle connected by a rubber hose or pipe, and depending on the situation, a brush can be attached to the nozzle for use.

[0006] Hand vacuum cleaners maximize portability; although lightweight, their short length may limit the cleaning area when sitting. Therefore, they are used to clean localized areas such as desks, sofas, or inside cars.

[0007] Stick vacuums can be used while standing, allowing for cleaning without bending over. This makes them advantageous for cleaning large areas. While handheld vacuums are used for cleaning narrow spaces, stick vacuums can clean larger areas and reach high places that are out of reach. Recently, stick vacuums are also being offered in modular types, allowing users to actively switch between different types of vacuums for various tasks.

[0008] In addition, recently, products that improve user convenience by allowing both handheld and stick vacuum cleaners to be used together are being released.

[0009] Korean Published Patent Application No. 10-2017-0112911 discloses an improved type of vacuum cleaner, and Korean Published Patent Application No. 10-2017-0126377 discloses a vacuum cleaner charging stand capable of mounting and charging such a vacuum cleaner. According to the disclosed vacuum cleaners, various types of suction nozzles can be connected to the suction part.

[0010] However, these vacuum cleaners and charging docks have a problem in that they cannot provide user-customized information. In other words, because they cannot actively provide users with cleaning-related information, there is a problem in that they cannot apply the Internet of Things (IoT), which is currently being applied to home appliances. For reference, the Internet of Things refers to a technology or environment in which sensors are attached to objects to exchange data in real time over the internet. Prior art literature

[0095] The above AI device (50) is a computing device capable of learning a neural network and can be implemented as various electronic devices such as a server, desktop PC, laptop PC, tablet PC, etc.

[0096] The AI ​​processor (51) can train a neural network using a program stored in memory (55). In particular, the AI ​​processor (51) can train a neural network for recognizing vehicle-related data. Here, the neural network for recognizing vehicle-related data can be designed to simulate the structure of the human brain on a computer and may include multiple network nodes having weights that simulate the neurons of a human neural network. The multiple network modes can exchange data according to their respective connection relationships to simulate the synaptic activity of neurons that exchange signals through synapses. Here, the neural network may include a deep learning model that has evolved from a neural network model. In the deep learning model, multiple network nodes can be located in different layers and exchange data according to convolutional connection relationships. Examples of neural network models include various deep learning techniques such as deep neural networks (DNN), convolutional deep neural networks (CNN), recurrent Boltzmann machines (RNN), restricted Boltzmann machines (RBM), deep belief networks (DBN), and deep Q-networks, and can be applied in fields such as computer vision, speech recognition, natural language processing, and speech / signal processing.

[0097] Meanwhile, a processor that performs the functions described above may be a general-purpose processor (e.g., CPU), but may also be an AI-dedicated processor for artificial intelligence learning (e.g., GPU).

[0098] The memory (55) can store various programs and data required for the operation of the AI ​​device (50). The memory (55) can be implemented as non-volatile memory, volatile memory, flash memory, hard disk drive (HDD), or solid-state drive (SDD). The memory (55) is accessed by the AI ​​processor (51), and the reading / writing / modification / deletion / updating of data by the AI ​​processor (51) can be performed. In addition, the memory (55) can store a neural network model (e.g., deep learning model (26)) generated through a learning algorithm for data classification / recognition according to one embodiment of the present specification.

[0099] Meanwhile, the AI ​​processor (51) may include a data learning unit (52) that learns a neural network for data classification / recognition. The data learning unit (52) can learn criteria regarding which training data to use to determine data classification / recognition, and how to classify and recognize data using the training data. The data learning unit (52) can learn a deep learning model by acquiring training data to be used for learning and applying the acquired training data to a deep learning model.

[0100] The data learning unit (52) may be manufactured in the form of at least one hardware chip and mounted on the AI ​​device (50). For example, the data learning unit (52) may be manufactured in the form of a dedicated hardware chip for artificial intelligence (AI), or may be manufactured as part of a general-purpose processor (CPU) or a dedicated graphics processor (GPU) and mounted on the AI ​​device (50). Additionally, the data learning unit (52) may be implemented as a software module. If implemented as a software module (or a program module containing instructions), the software module may be stored on a non-transitory computer-readable media. In this case, at least one software module may be provided by an operating system (OS) or by an application.

[0101] The data learning unit (52) may include a learning data acquisition unit (53) and a model learning unit (54).

[0102] The training data acquisition unit (53) can acquire training data required for a neural network model for classifying and recognizing data. For example, the training data acquisition unit (53) can acquire vehicle data and / or sample data to be input into a neural network model as training data.

[0103] The model learning unit (54) can learn to have a judgment criterion regarding how a neural network model classifies a predetermined data using the acquired learning data. At this time, the model learning unit (54) can train the neural network model through supervised learning, which uses at least a portion of the learning data as a judgment criterion. Alternatively, the model learning unit (54) can train the neural network model through unsupervised learning, which discovers a judgment criterion by learning on its own using the learning data without supervision. In addition, the model learning unit (54) can train the neural network model through reinforcement learning using feedback on whether the result of the situation judgment based on learning is correct. Furthermore, the model learning unit (54) can train the neural network model using a learning algorithm including error back-propagation or gradient descent.

[0104] When the neural network model is trained, the model training unit (54) can store the trained neural network model in memory. The model training unit (54) can also store the trained neural network model in the memory of a server connected to the AI ​​device (50) via a wired or wireless network.

[0105] The data learning unit (52) may further include a learning data preprocessing unit (not shown) and a learning data selection unit (not shown) to improve the analysis results of the recognition model or to save resources or time required to create the recognition model.

[0106] The learning data preprocessing unit can preprocess the acquired data so that the acquired data can be used for learning to make situational judgments. For example, the learning data preprocessing unit can process the acquired data into a pre-set format so that the model learning unit (54) can use the acquired learning data for learning to recognize images.

[0107] Additionally, the training data selection unit may select data necessary for training from among the training data acquired by the training data acquisition unit (53) or the training data preprocessed by the preprocessing unit. The selected training data may be provided to the model training unit (54). For example, the training data selection unit may select only the data regarding objects included in a specific area as training data by detecting a specific area among the images acquired through the camera of the intelligent electronic device.

[0108] Additionally, the data learning unit (52) may further include a model evaluation unit (not shown) to improve the analysis results of the neural network model.

[0109] The model evaluation unit inputs evaluation data into a neural network model, and if the analysis result output from the evaluation data does not satisfy a predetermined standard, it may cause the model learning unit (52) to learn again. In this case, the evaluation data may be predefined data for evaluating a recognition model. For example, the model evaluation unit may evaluate that the predetermined standard is not satisfied if, among the analysis results of the recognition model learned for the evaluation data, the number or ratio of evaluation data for which the analysis result is inaccurate exceeds a preset threshold.

[0110] The communication unit (57) can transmit the AI ​​processing results by the AI ​​processor (51) to an external electronic device.

[0111] The above external electronic devices may include autonomous vehicles, robots, drones, AR devices, mobile devices, home appliances, etc.

[0112] For example, if the above external electronic device is an autonomous vehicle, the AI ​​device (50) may be defined as another vehicle or 5G network that communicates with the autonomous driving module vehicle. Meanwhile, the AI ​​device (50) may be functionally embedded and implemented in an autonomous driving module equipped within the vehicle. Additionally, the 5G network may include a server or module that performs autonomous driving-related control.

[0113] Meanwhile, although the AI ​​device (50) illustrated in FIG. 4 is described by functionally separating it into an AI processor (51), memory (55), and communication unit (57), it should be noted that the aforementioned components may be integrated into a single module and referred to as an AI module.

[0114] FIG. 5 is an exploded perspective view showing a vacuum cleaner (100) according to one embodiment.

[0115] Referring to FIG. 5, the vacuum cleaner (100) may include a vacuum cleaner body (200), a cleaning module (210) coupled to the vacuum cleaner body (200), a length adjustment member (220) connecting the vacuum cleaner body (200) and the cleaning module (210), a battery (400) coupled to the vacuum cleaner body (200), and a vacuum cleaner stand (300) on which the vacuum cleaner body (200) is mounted.

[0116] The vacuum cleaner body (200) may include a body portion (201) in which a suction motor (not shown) that generates suction power and a cyclone flow device (not shown) that separates dust from the sucked air are installed, a handle portion (202) connected to the rear of the body portion (201) and which can be grasped by a user, and a connecting portion (203) connected to the front of the body portion (201) to which a cleaning module (210) or a length adjustment member (220) is coupled.

[0117] The cleaning module (210) may include a suction part (211) for sucking up dust, etc., and a coupling part (212) that is coupled to the main body (200) of the vacuum cleaner or the length adjustment member (220).

[0118] One end of the length adjustment member (220) may be connected to the vacuum cleaner body (200), and the other end may be connected to the cleaning module (210). The length adjustment member (220) may adopt a structure in which the length is variable. The length adjustment member (220) may adopt a material that is elastically changeable. Furthermore, one end of the length adjustment member (220) may be connected to the vacuum cleaner body (200), and a suction part (not shown) may be provided at the other end, so that it can perform a suction function without a separate cleaning module being connected.

[0119] The battery (400) can be detachably connected to the body portion (201) of the vacuum cleaner body (200) to supply power for driving the vacuum cleaner (100). The battery (400) can also be detachably connected to the battery receiving portion (302) of the vacuum cleaner stand (300) to allow for charging. Additionally, two batteries (400) are provided, one of which is connected to the vacuum cleaner body (200) to supply power, and the other one of which is connected to the vacuum cleaner stand (300) to be charged.

[0120] The vacuum cleaner stand (300) may include a stand-type or wall-mounted body part (301), a battery receiving part (302) in which a battery (400) is charged, a vacuum cleaner support part (303) that supports the vacuum cleaner body (200), and a charging part (304) that is electrically connected to the battery (400) coupled to the vacuum cleaner body (200).

[0121] Although the drawing shows a wall-mounted body part (301), it may also include a stand-type body part (not shown) that is set up to stand on the floor.

[0122] And, while the vacuum cleaner body (200) is supported by the vacuum cleaner support (303), the battery (400) can be electrically connected to the charging unit (304). Thus, the user can charge the battery (400) while the vacuum cleaner body (200) is mounted on the vacuum cleaner stand (300).

[0123] And the vacuum cleaner stand (300) can be electrically connected to an external outlet (311) via a power line (310). The current delivered via the power line (310) can charge the first battery housed in the vacuum cleaner body (200) through the charging part (304) of the vacuum cleaner stand and charge the second battery housed in the battery housing (302).

[0124] In addition, the vacuum cleaner (100) may have a suction unit that performs various functions modularly mounted on the vacuum cleaner body (200). That is, multiple cleaning modules (210) are provided according to function, and the user can use the cleaning module (210) suitable for the cleaning target by attaching it to the vacuum cleaner body (200).

[0125] The cleaning module (210) may include a cleaning module equipped with a basic suction port for hardwood floors, a cleaning module equipped with a suction port for bedding, a cleaning module equipped with a suction port for mattresses, a cleaning module equipped with a suction port for carpets, and a cleaning module equipped with a wet mop. In addition, dedicated cleaning modules for various functions such as cleaning hardened dust, cleaning bendable crevices, and cleaning tops may be provided as modules.

[0126] The drawing also shows a cleaning module (221) equipped with a 2-in-1 suction port and a cleaning module (222) equipped with a crevice suction port mounted on a vacuum cleaner stand (300). The cleaning module (221) equipped with a 2-in-1 suction port can adjust the length of the brush by operating a button, so it can be used in a basic form when cleaning sofas or mattresses, and in a brush form when cleaning picture frames or furniture. The cleaning module (222) equipped with a crevice suction port is provided with a suction port in the form of a narrow nozzle, which is advantageous for sucking up dust and other debris by inserting it into narrow crevices.

[0127] FIG. 6 is a figure showing a control method of a vacuum cleaner (100) according to one embodiment.

[0128] The vacuum cleaner (100) according to the embodiment of the present specification is provided in a modular manner in which a cleaning module (210) is detachable, and can be used by changing an appropriate cleaning module (210) as needed.

[0129] The vacuum cleaner body (200) can receive information about the cleaning module in use and load information from the cleaning module (210). For example, the main circuit (MCU: Micro Controller Unit) provided in the vacuum cleaner body (200) can distinguish and store which cleaning module (210) is currently in use by measuring the current value (or voltage value) from the power line connected to the cleaning module (210).

[0130] In addition, since the current value of the power line may vary depending on the load applied to the cleaning module (210), the main circuit may also store and utilize load information or torque information applied to the cleaning module (210). For reference, the torque of the motor is proportional to the load current flowing through the rotor. When the load of the motor increases, the load current increases, and the torque increases to balance the load, allowing for continued stable operation. The relationship between torque and load current can be determined through a torque characteristic curve, etc.

[0131] And the main circuit can store information regarding which cleaning module (210) was used at which time and for what duration, i.e., usage time information. And if the usage mode can be classified into strong / medium / weak depending on the rotational force of the suction motor of the vacuum cleaner body (200), the main circuit can store the usage time and usage output for each usage mode used by the user. And along with this information, the main circuit can transmit the accumulated usage time and usage frequency information for each cleaning module used by the user to the server (30).

[0132] The server (30) can provide cleaning history information to the user using accumulated information. The server (30) can also analyze the user's cleaning pattern and recommend a cleaning type required for the smart device (20) or vacuum cleaner (100) to notify the user that the cleaning time has arrived. For example, when analyzing the accumulated data of the vacuum cleaner (100), if it has been 2 months since the last cleaning of bedding, the user can be notified that it is time to clean the bedding through the application of the smart device (20).

[0133] In addition, the server (30) can notify that the cleaning time for the cleaning module (210) component has arrived, or that the cleaning module (210) has broken down or the replacement time has passed.

[0134] FIG. 7 is a block diagram showing the connection relationship of the vacuum cleaner (100).

[0135] Referring to FIG. 7(a), the cleaning module (210) and the vacuum cleaner body (200) are physically connected via a power line, the vacuum cleaner body (200) and the server (30) are connected via wireless communication, and the server (30) and the smart device (20) can be connected via wireless communication.

[0136] The connection part between the cleaning module (210) and the vacuum cleaner body (200) may be provided with a suction pipe that serves as a passage for dust sucked in by the cleaning module (210) to move, and a power line to provide power to the cleaning module (210), through which the suction force generated from the vacuum cleaner body (200) is transmitted to the cleaning module (210).

[0137] And the main circuit of the vacuum cleaner body (200) can obtain information about which cleaning module (210) is connected, whether it is currently in use, and the magnitude of the applied load or torque through the current value (or voltage value) of the power line.

[0138] Referring to FIG. 7(b), the cleaning module (210) and the vacuum cleaner body (200) are physically connected via a power line and are connected via wired communication, the vacuum cleaner body (200) and the server (30) are connected via wireless communication, and the server (30) and the smart device (20) can be connected via wireless communication.

[0139] The connection portion between the cleaning module (210) and the vacuum cleaner body (200) may be provided with a suction pipe that serves as a passage for dust sucked in by the cleaning module (210) to move, a power line to provide power to the cleaning module (210), and a communication line to transmit usage information of the cleaning module (210), through which suction power generated from the vacuum cleaner body (200) is transmitted to the cleaning module (210).

[0140] Furthermore, the main circuit of the vacuum cleaner body (200) can obtain information regarding which cleaning module (210) is connected, whether it is currently in use, and the magnitude of the applied load through information from the communication line. The current (or voltage) information of the power line contains noise, and if the magnitude of the noise is relatively large, it may be impossible to identify the information to be obtained from it. In such cases, by using a separate communication line, only the information to be obtained can be transmitted through a separate line. For example, when a cleaning module dedicated to bedding is connected and used, the operating current is very weak, so it may be difficult to obtain usage information through the power line. In this case, a communication line is provided separately from the power line, and usage information of the cleaning module (210) is transmitted through the communication line, making it possible to transmit information without any omissions.

[0141] Referring to FIG. 7 (c), the cleaning module (210) and the vacuum cleaner body (200) are physically connected via a power line and are also connected via wireless communication, the vacuum cleaner body (200) and the server (30) are connected via wireless communication, and the server (30) and the smart device (20) can be connected via wireless communication.

[0142] The cleaning module (210) may be provided with a transmitter for wirelessly transmitting usage information. The main body of the vacuum cleaner (200) may be provided with a receiver for receiving information from the cleaning module (210).

[0143] And the main circuit of the vacuum cleaner body (200) can obtain information through the information of the receiver regarding which cleaning module (210) is connected, whether it is currently in use, and the magnitude of the applied load. As a means of wireless communication that can be used, Zigbee or Bluetooth, etc., may be used.

[0144] FIG. 8 is a cross-sectional view showing the connection portion of the vacuum cleaner body (200) and the cleaning module (210) according to the first embodiment, and FIG. 9 is a plan view showing the connection portion of the vacuum cleaner body (200) and the cleaning module (210) according to the first embodiment, respectively.

[0145] The vacuum cleaner body (200) may have a connecting part (203) formed therein, which is connected to the front of the body part (201) and to which a cleaning module (210) or a length adjustment member (220) is coupled. The connecting part (203) may be provided in the form of a tube protruding from the front of the body part (201).

[0146] Additionally, a connecting part (212) that is coupled to a connecting part (203) may be formed at one end of the cleaning module (210) or the length adjustment member (220). The connecting part (212) may be provided in the form of a tube that can accommodate the connecting part (203). At this time, the inner diameter of the connecting part (212) may be the same as or slightly larger than the outer diameter of the connecting part (203).

[0147] The connecting part (203) and the coupling part (212) can be detachably coupled, and, for example, can be provided by the combination of a coupling groove (203c) formed to be recessed on the outer surface of the connecting part (203) and a coupling projection (212c) formed to be protruded on the inner surface of the coupling part (212).

[0148] And the connecting projection (212c) is connected to the connecting part (212) by a hinge and can be supported by an elastic member such as a coil spring. That is, when a user inserts the connecting part (203) into the inner space of the connecting part (212), the connecting projection (212c) is pressed while pressing the elastic member, and when the insertion of the connecting part (203) is completed, the connecting projection (212c) is fitted into the connecting groove (203c) by the restoring force of the elastic member. Thus, the connecting part (203) and the connecting part (212) can be firmly connected.

[0149] When separating, a pusher provided on the outer surface of the coupling part (212) may be used. When the user presses the pusher, the coupling projection (212c) connected thereto is pressed while pressing the elastic member. That is, the coupling projection (212c) is separated from the coupling groove (203c), and the connecting part (203) can be separated from the coupling part (212).

[0150] The connection part (203) may be provided with a first suction pipe (203a) that transmits the suction power generated from the vacuum cleaner body (200) to the cleaning module (210) and serves as a passage for dust sucked in by the cleaning module (210) to move, and a first power connection part (203b) for providing power to the cleaning module (210).

[0151] And the connecting part (212) may be provided with a second suction pipe (212a) through which the suction force of the connecting part (203) is transmitted and which serves as a passage for dust sucked in from the cleaning module (210) to move, and a second power connection part (212b) for receiving power from the first power connection part (203b).

[0152] The first and second power connection portions (203b, 212b) may be provided on one side of the first and second suction tubes (203a, 212a) and may be provided in a shape in which two terminals are connected. For example, the second power connection portion (212b) may be provided so that both terminals protrude, and the first power connection portion (203b) may be provided so that the negative terminal is recessed, so that the second power connection portion (212b) can be inserted.

[0153] That is, as the connecting part (203) and the coupling part (212) are combined, the suction pipe (203a, 212a) and the power connection part (203b, 212b) can be connected simultaneously.

[0154] FIG. 10 is a plan view showing the joint portions of the vacuum cleaner body (200) and the cleaning module (210) according to the second embodiment.

[0155] The connection part (203) may be provided with a first suction pipe (203a) that transmits the suction power generated from the vacuum cleaner body (200) to the cleaning module (210) and serves as a passage for dust sucked in by the cleaning module (210), a first power connection part (203b) for providing power to the cleaning module (210), and a first information connection part (203d) that is connected to the second information connection part (212d) described later to receive information.

[0156] And the connecting part (212) may be provided with a second suction pipe (212a) through which the suction power of the connecting part (203) is transmitted and which serves as a passage for dust sucked in from the cleaning module (210) to move, a second power connection part (212b) for receiving power from the first power connection part (203b), and a second information connection part (212d) for transmitting information of the cleaning module (210) to the main circuit of the vacuum cleaner body (200).

[0157] The first and second power connection portions (203b, 212b) may be provided on one side of the first and second suction tubes (203a, 212a) and may be provided in a shape in which two terminals are connected. For example, the second power connection portion (212b) may be provided so that both terminals protrude, and the first power connection portion (203b) may be provided so that the negative terminal is recessed, so that the second power connection portion (212b) can be inserted.

[0158] In addition, the first and second information connection parts (203d, 212d) may be provided adjacent to the first and second power connection parts (203b, 212b) and may be provided in a shape in which one terminal is connected. For example, the second information connection part (212d) may be provided so that one terminal protrudes, and the first information connection part (203d) may be provided so that a negative terminal is recessed, so that the second power connection part (212d) can be inserted.

[0159] That is, as the connecting part (203) and the coupling part (212) are combined, the suction pipe (203a, 212a), the power connecting part (203b, 212b), and the information connecting part (203d, 212d) can be connected simultaneously.

[0161] Hereinafter, a method for providing customized cleaning information using a vacuum cleaner according to an embodiment of the present specification will be described.

[0162] FIG. 11 is a block diagram showing a method for providing customized cleaning information according to a first embodiment in chronological order.

[0163] The vacuum cleaner (100) is configured such that a cleaning module (210) equipped with various functions is provided in a modular manner, and the modular cleaning module (210) is combined to perform various functions.

[0164] Referring to FIG. 11, the user can combine cleaning modules (210) of the vacuum cleaner (100) as needed (S100). Information on available cleaning modules is stored in advance in the memory (105, see FIG. 3) of the vacuum cleaner (100). For example, the cleaning modules (210) may include a cleaning module equipped with a basic floor suction port, a cleaning module equipped with a bedding-specific suction port, a cleaning module equipped with a mattress-specific suction port, a cleaning module equipped with a carpet-specific suction port, and a cleaning module equipped with a mop. In addition, dedicated cleaning modules that perform various functions, such as cleaning hardened dust, cleaning bendable crevices, and cleaning tops, may be provided as modules.

[0165] Next, the control unit (101, see FIG. 3) of the vacuum cleaner (100) can identify which of the cleaning modules stored in memory (105) the combined cleaning module (210) corresponds to (S110). Meanwhile, unlike the drawing, the step of recognizing the cleaning module may be performed at the server (30), in which case the server can recognize and identify the cleaning module after the cleaning information transmission step (S150) described later.

[0166] When the user starts cleaning using the vacuum cleaner (100) (S120), information received from the sensing unit (104, see FIG. 3) of the vacuum cleaner (100) is stored in the memory (105) (S130). Then, when the user places the vacuum cleaner (100) on the stand (S140), the control unit (101) transmits information to the server (30) through the communication module (106) (S150).

[0167] The cleaning-related information transmitted from the vacuum cleaner (100) to the server (30) may include the type of the cleaning module (210) that was executed, the start and end times of the operation of the vacuum cleaner (100), the time the vacuum cleaner (100) was operated, the usage mode selected in the vacuum cleaner, the load information applied to the vacuum cleaner (100), the contamination information of the vacuum cleaner (100) or the cleaning module (210), or the remaining battery level information.

[0168] The server (30) accumulates and stores information transmitted from the vacuum cleaner (100) (S160). For example, the server (30) can convert the usage history of the vacuum cleaner (100) into data and store it. It can also store it separately by cleaning module (210).

[0169] Then, the server (30) analyzes cleaning history information through accumulated data (S170). For example, the server (30) can derive useful information for the user by analyzing information regarding a cleaning module (210) for which the time for reuse has arrived after exceeding a certain period of use, information regarding a cleaning module (210) that requires cleaning or replacement because the accumulated usage time has exceeded a standard time, or information regarding the remaining lifespan of the battery.

[0170] Then, the server (30) provides a notification to a smart device (20) that stores an application (APP) synchronized with the vacuum cleaner (100) (S180). For example, the server (30) may provide a notification that the cleaning time for the object being cleaned using the cleaning module (210) has arrived after a certain amount of time has elapsed since the cleaning module (210) was used. Alternatively, the server (30) may provide a notification that the cleaning module (210) needs to be cleaned because the accumulated usage time after the cleaning module (210) was cleaned has exceeded a standard time, or that the cleaning module (210) needs to be replaced or repaired because the accumulated usage time after the cleaning module (210) was first used has exceeded a standard time. Alternatively, the server (30) may provide a notification that the battery needs to be replaced because there is not much remaining battery life.

[0171] FIG. 12 is a flowchart illustrating a method for providing customized cleaning information according to a first embodiment.

[0172] The method for providing customized cleaning information according to the first embodiment begins by collecting information regarding the cleaning module (210) from the sensor of the vacuum cleaner (100) (S200).

[0173] The vacuum cleaner (100) can identify the cleaning module (210) in use by using the collected information (S220). Alternatively, the server (30) that receives information from the vacuum cleaner (100) may perform the task of identifying the cleaning module (210).

[0174] And the vacuum cleaner (100) stores usage time information of a specific cleaning module (210) (S240). At this time, usage time information can be stored for each cleaning module (210).

[0175] The server (30) can calculate the time of non-use by comparing the last time of use of the cleaning module (210) with the current time, and can determine whether the time of non-use is greater than the standard elapsed time by comparing it with the standard elapsed time (S260). Alternatively, this determination may be performed by a processor within the cleaning device (100).

[0176] The server (30) may provide a notification that the cleaning module (210) needs to be used if the period of non-use of the specific cleaning module (210) is longer than the standard elapsed time (S280). This notification may be delivered to the vacuum cleaner (100) or to a smart device (20) that stores an application linked to the vacuum cleaner (100).

[0177] Through this notification, the user can know that it is time to clean a specific item. For example, if the standard elapsed time for a bedding-only cleaning module is 30 days, and 30 days have passed since the last use of the bedding-only cleaning module, a notification may be provided on the smartphone saying, "It has been 30 days since you cleaned the bedding, so please start cleaning the bedding!"

[0178] FIG. 13 is a flowchart illustrating a method for providing customized cleaning information according to a second embodiment.

[0179] The method for providing customized cleaning information according to the second embodiment may include additional notification information compared to the first embodiment described in FIG. 12. Description of parts that overlap with the first embodiment will be omitted.

[0180] The method for providing customized cleaning information according to the second embodiment begins by collecting information regarding the cleaning module (210) from the sensor of the vacuum cleaner (100) (S200).

[0181] The vacuum cleaner (100) can identify the cleaning module (210) in use by using the collected information (S220). Alternatively, the server (30) that receives information from the vacuum cleaner (100) may perform the task of identifying the cleaning module (210).

[0182] And the vacuum cleaner (100) stores usage time information of a specific cleaning module (210) (S250). At this time, usage time information can be stored for each cleaning module (210).

[0183] The server (30) can calculate the total accumulated usage time by adding the usage time of the newly delivered cleaning module (210) to the usage time of the cleaning module (210) accumulated so far, and can determine whether the accumulated usage time is greater than the reference accumulated time by comparing it with the reference accumulated time (S270). Alternatively, this determination may be performed by a processor within the vacuum cleaner (100).

[0184] The server (30) may provide a notification that cleaning or replacement of a specific cleaning module (210) is required if the accumulated usage time of the cleaning module (210) is greater than the accumulated usage time (S290). This notification may be delivered to the vacuum cleaner (100) or to a smart device (20) that stores an application linked to the vacuum cleaner (100).

[0185] The user can know through the notification that the time has come for cleaning or replacing a specific cleaning module (210). For example, if the standard cumulative time required for cleaning a bedding-only cleaning module is 360 minutes, and 360 minutes have been used since the last cleaning of the bedding-only cleaning module, a notification saying "The bedding cleaning module (210) needs cleaning" may be provided on the smartphone. Alternatively, if the standard cumulative time required for replacement of the bedding-only cleaning module is 3600 minutes, and 3600 minutes have been used since the last time the bedding-only cleaning module was used for the first time, a notification saying "The bedding cleaning module (210) needs replacement" may be provided on the smartphone.

[0186] FIG. 14 is a flowchart illustrating a method for providing customized cleaning information according to a third embodiment.

[0187] The method for providing customized cleaning information according to the third embodiment may have additional steps compared to the second embodiment described in FIG. 13. Description of parts that overlap with the second embodiment will be omitted.

[0188] The method for providing customized cleaning information according to the third embodiment begins by collecting information regarding the cleaning module (210) from the sensor of the vacuum cleaner (100) (S200).

[0189] The vacuum cleaner (100) can identify the cleaning module (210) in use by using the collected information (S220). Alternatively, the server (30) that receives information from the vacuum cleaner (100) may perform the task of identifying the cleaning module (210).

[0190] And the vacuum cleaner (100) can distinguish and store the usage mode of the cleaning module (210) (S230). For example, the usage mode can be classified into strong / medium / weak depending on the rotational force of the suction motor of the vacuum cleaner body (200).

[0191] And the vacuum cleaner (100) can convert cleaning information data by applying weights for each usage mode. For example, the weight for strong mode is 3, the weight for medium mode is 2, and the weight for weak mode is 1, and a new total usage time with weights reflected can be derived by multiplying the weight corresponding to the total usage time in each usage mode.

[0192] And the vacuum cleaner (100) stores usage time and usage time information with weights reflected in a specific cleaning module (210) (S240, S250).

[0193] The subsequent steps are the same as before.

[0194] FIG. 15 is a flowchart illustrating a method for providing customized cleaning information according to a fourth embodiment.

[0195] The method for providing customized cleaning information according to the fourth embodiment begins by collecting information regarding the cleaning module (210) from the sensor of the vacuum cleaner (100) (S200).

[0196] The vacuum cleaner (100) can identify the cleaning module (210) in use by using the collected information (S220). Alternatively, the server (30) that receives information from the vacuum cleaner (100) may perform the task of identifying the cleaning module (210).

[0197] And the vacuum cleaner (100) stores usage time information and usage time information of a specific cleaning module (210) (S300). At this time, usage time information and usage time information can be stored for each cleaning module (210).

[0198] The server (30) can generate a user's cleaning pattern using usage time information and usage time information for each cleaning module (210) (S310). For example, based on the user's recorded cleaning information, a cleaning pattern can be generated that follows floor cleaning, then bedding cleaning, then mattress cleaning, and finally mop cleaning. Alternatively, this determination may be performed by a processor within the vacuum cleaner (100).

[0199] And the server (30) can provide information about these cleaning patterns to the user (S320). For example, the server (30) can identify the location of the cleaning step currently in progress within the cleaning pattern and provide the user with information about the next cleaning target or a cleaning module (210) that can be used therefor. This notification may be delivered to the vacuum cleaner (100) or to a smart device (20) that stores an application linked to the vacuum cleaner (100).

[0200] Users can plan their cleaning through the notification and prevent cleaning steps from getting mixed up or accidentally skipping some cleaning steps.
