Description

Technical Field

[0001] The present invention relates to the field of home appliance control, and specifically provides a home appliance and an operation control method thereof. Background Art

[0002] There are more and more types of cleaning equipment available, such as washing machines, dryers, sweepers, mops, etc. Placing several cleaning equipment at home will take up a large floor space, reducing the available area in the room and causing inconvenience to users' lives. If you encounter equipment that needs to be connected to water pipes, you will also need to occupy wall space to install the water pipes, which not only takes up space, but the exposed water pipes will also affect the appearance, and connecting the water pipes will also cost more money.

[0003] In order to alleviate this situation, integrated home appliances can be used, such as an all-in-one cleaning machine. The all-in-one cleaning machine includes a clothing processing device and a floor cleaning device. The floor cleaning device includes a mobile cleaning device and a base station. The clothing processing device can be set above the floor cleaning device. This not only facilitates the operation of the floor cleaning device, but also reduces the footprint of the clothing processing device and the floor cleaning device. If the inlet and outlet pipes can be shared, it can further save wall space and improve the quality of life of users.

[0004] In actual use, the floor cleaning device and the laundry processing device operate independently. However, since they share a common space, if the floor cleaning device and the laundry processing device need to operate simultaneously, the operation of one appliance may affect the performance of the other, affecting the user experience. For example, when the laundry processing device is performing a process such as dehydration, the laundry processing device will cause the entire cleaning machine to vibrate, which can affect the mobile cleaning device's entry and exit from the base station or affect the normal charging of the mobile cleaning device.

[0005] In order to solve this problem, the existing technology requires that the clothing processing equipment and the floor cleaning equipment establish real-time communication and information exchange to obtain the operating status of the clothing processing equipment and the floor cleaning equipment and send requests, so as to adjust the operating status of one party in time according to the operating status of the other party, and avoid the clothing processing equipment and the floor cleaning equipment from affecting each other. However, during actual use, network disconnection may occur, which will affect the real-time communication between the clothing processing equipment and the floor cleaning equipment, and thus affect the normal operation of the clothing processing equipment and the floor cleaning equipment.

[0006] Accordingly, the art requires a new home appliance operation control method to solve the above problems. Summary of the Invention

[0007] The present invention aims to solve the aforementioned technical problem, namely, to address the prior art issue of network outages affecting the interaction between a laundry processing device and a floor cleaning device. To this end, the present invention provides a household appliance and a method for controlling its operation, the household appliance comprising a laundry processing device and a floor cleaning device. The method comprises the following steps: the laundry processing device transmits operating parameters of a currently executed program to the floor cleaning device; the floor cleaning device receives and analyzes the operating parameters and determines subsequent execution actions based on the operating parameters.

[0008] In the above-mentioned specific implementation of the household appliance operation control method, "determining the subsequent execution action based on the operating parameters" is specifically: analyzing the current state of the clothing processing device and the time when the clothing processing device enters and / or ends the vibration state based on the operating parameters; the floor cleaning device determines, based on the analysis results, whether the clothing processing device will affect the preparatory operation action of the floor cleaning device; if so, the floor cleaning device adjusts and / or replaces the preparatory operation action to cooperate with the clothing processing device; if not, the floor cleaning device executes the preparatory operation action.

[0009] In the above-mentioned specific implementation of the household appliance operation control method, the floor cleaning equipment includes a mobile cleaning device and a base station, and the mobile cleaning device enters and exits the base station; "the floor cleaning device analyzes the operating parameters after receiving them" specifically means: the mobile cleaning device analyzes the operating parameters in real time after receiving them; and / or the mobile cleaning device analyzes the operating parameters before entering and exiting the base station.

[0010] In the above specific implementation of the household appliance operation control method, after receiving the operation parameters, the floor cleaning device sends feedback information to the clothes processing device.

[0011] In the above specific implementation of the household appliance operation control method, if the clothing processing device does not receive the feedback information, a retransmission mechanism is started.

[0012] In the above-mentioned specific implementation of the household appliance operation control method, the retransmission mechanism is specifically: storing the operating parameters in the cloud, and the cloud sends the operating parameters to the floor cleaning device again.

[0013] In the above-mentioned specific implementation of the household appliance operation control method, if the clothes processing device is started multiple times, the floor cleaning device will receive multiple operation parameters, and the later operation parameters will overwrite the earlier operation parameters.

[0014] In the above-mentioned specific implementation of the household appliance operation control method, a communication connection is established between the clothing processing device and the floor cleaning device, and the communication method is one of Bluetooth, wireless network (WiFi), mobile cellular network, gateway wireless or wired.

[0015] In the above specific implementation of the household appliance operation control method, the operation parameters include: one or more of water filling time, washing time, rinsing time, heating time, dehydration time, washing mode or motor speed.

[0016] A household appliance comprises a controller, wherein the controller is configured to execute any one of the above methods.

[0017] While adopting the above-mentioned technical solution, the present invention selects another linkage control method, in which the laundry processing device sends the operating parameters contained in the currently executed program to the floor cleaning device; the floor cleaning device analyzes the operating parameters after receiving them and determines the subsequent execution action based on the operating parameters. In this way, the laundry processing device only needs to send the operating parameters once, and after sending the operating parameters, the laundry processing device does not need to maintain a constant communication state with the floor cleaning device. Therefore, even if a sudden network disconnection or signal anomaly occurs, it will basically not affect the coordination between the laundry processing device and the floor cleaning device. This largely avoids the interference of the network disconnection on the coordination between the laundry processing device and the floor cleaning device, allowing the cleaning machine to operate normally.

[0022] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not used to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the description is combined with a washing machine, this is not restrictive, and those skilled in the art can apply the present invention to any other clothing processing equipment as needed, as long as the clothing processing equipment needs to avoid affecting the normal operation of the sweeper during use.

[0023] It should be noted that, in the description of the present invention, terms such as "upper," "lower," "left," "right," "inner," and "outer" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are used solely for ease of description and are not intended to indicate or imply that the relevant devices or components must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, ordinal numbers such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] Furthermore, in order to more clearly demonstrate the core technical solution of the present invention, the description of the well-known structures of the washing machine and the sweeper is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the washing machine and the sweeper can be without these structures.

[0026] like Figure 1 As shown, the present invention proposes a method for controlling the operation of a household appliance, wherein the household appliance includes a clothes processing device and a floor cleaning device, wherein the floor cleaning device includes a mobile cleaning device and a base station, and the mobile cleaning device enters and exits the base station. The clothes processing device is used to clean clothes, and can be a drum washing machine, a pulsator washing machine, an agitator washing machine, a clothes dryer, a shoe washing machine, a clothes care machine, and other laundry devices can also be used in this solution; the floor cleaning device can be a sweeping robot, a mopping robot, a sweeping and mopping robot, a sweeping and mopping robot, or a floor scrubber; the method for controlling the operation of the household appliance includes the following steps: the clothes processing device sends the operating parameters contained in the currently executed program to the floor cleaning device; the floor cleaning device analyzes the operating parameters after receiving them, and determines the subsequent execution action based on the operating parameters.

[0027] In order to solve the problem in the prior art that network outages affect the coordination between the clothing processing equipment and the floor cleaning equipment, this embodiment adopts another linkage control method. The original linkage control method is that the clothing processing equipment receives a start-up instruction and then executes the start-up instruction; after receiving the start-up instruction, the floor cleaning equipment obtains its current status from the clothing processing equipment and then determines the subsequent execution action based on the current status of the clothing processing equipment. Therefore, once the network is disconnected, it will affect the floor cleaning equipment's acquisition of the clothing processing equipment status, and the subsequent operation of the floor cleaning equipment may be affected by the clothing processing equipment. For example, if the mobile cleaning device of the floor cleaning equipment returns to the base station for charging, if the clothing processing equipment performs a program with a large vibration amplitude, such as dehydration, the clothing processing equipment will cause the entire cleaning machine to vibrate, which will naturally cause the base station to vibrate. The charging port of the mobile cleaning device and the charging base of the base station will rub against each other, affecting charging. In serious cases, sparks will be generated, resulting in electrical hazards.

[0028] In the present invention, taking a washing machine and a floor sweeper as examples, a user sets the parameters of the current washing program on the washing machine and then starts the washing program; the clothing processing device receives and executes the start command, and the operating parameters contained in the washing program will also be sent to the floor sweeper. These parameters are not limited to the parameters set by the user, but can also include process parameters for each stage of the program, such as water filling time, washing time, rinsing time, heating time, dehydration time, washing method or motor speed, and one or more parameters that affect the washing process; after receiving the operating parameters, the floor cleaning device analyzes the working status of the clothing processing device at each time point, thereby planning its subsequent execution actions to avoid being affected by the clothing processing device; in this way, the clothing processing device only needs to send the operating parameters once, and after sending the operating parameters, the clothing processing device does not need to maintain a communication state with the floor cleaning device. Therefore, even if a sudden network outage or signal abnormality occurs, the cooperation between the clothing processing device and the floor cleaning device will basically not be affected, and the interference of the network outage on the cooperation between the clothing processing device and the floor cleaning device is largely avoided, so that the cleaning all-in-one can operate normally. Since the clothing processing device in the present invention does not need to maintain a communication state with the floor cleaning device, a lot of traffic can be saved, reducing usage costs.

[0029] The floor cleaning device can also plan its own work in advance according to the operating parameters of the clothing processing device. For example, to avoid the clothing processing device being in a vibrating state while the mobile cleaning device enters the base station or is charging, the work can be planned in advance according to the parameters of the clothing processing device. If the mobile cleaning device takes 2 hours to charge, the clothing processing device needs to be in a non-vibrating state for 2 hours. According to the operating parameters, the mobile cleaning device can enter the base station in a non-vibrating state to charge. When the clothing processing device is about to enter the vibrating state, the charging is stopped. When the clothing processing device enters the non-vibrating state again, the mobile cleaning device resumes charging. In order to enter the base station before the battery is exhausted, the mobile cleaning device can plan the cleaning area and power consumption in advance according to the operating parameters.

[0030] The clothing processing device may send operating parameters to the floor cleaning device in real time or with one click. A synchronization button may be set on the clothing processing device, and the customer may subjectively control the clothing processing device to synchronize information at a certain node. The node for sending the operating parameters may be after the clothing processing device receives the start-up instruction and before executing the start-up instruction, or after the clothing processing device starts executing the start-up instruction, or after the clothing processing device has executed the start-up instruction for a period of time, as long as it does not affect the normal operation of the floor cleaning device.

[0031] During the same time period, the clothing processing equipment may be started multiple times, for example, if the user washes multiple times or resets the parameters. If the floor cleaning equipment analyzes based on the previous operating parameters, the clothing processing equipment may be in a vibrating state when the mobile cleaning device returns to the base station. In order to avoid this delay, real-time analysis can be used.

[0032] Further, if Figure 2As shown, the floor cleaning equipment includes a mobile cleaning device and a base station, and "determining the subsequent execution action based on the operating parameters" is specifically: the mobile cleaning device analyzes the current state of the clothing processing device and the time when the clothing processing device enters and / or ends the vibration state based on the received operating parameters; the floor cleaning device determines whether the clothing processing device will affect the preparatory operation action of the floor cleaning device based on the analysis results; if so, the floor cleaning device adjusts and / or changes the preparatory operation action to cooperate with the clothing processing device; if not, the floor cleaning device performs the preparatory operation action. The mobile cleaning device can choose to analyze the operating parameters within a certain distance of returning to the base station, or can choose to analyze the operating parameters before performing the preparatory operation, or analyze the operating parameters before starting the work to plan its own work, or can analyze at other nodes, which does not exceed the scope of protection of the present invention. The floor cleaning device adjusts and / or changes the preparatory operation action, including but not limited to: waiting outside the base station, continuing cleaning, or performing other functions, such as voice reminders, voice broadcasts, etc.

[0033] For example, the mobile cleaning device is preparing to enter the base station, that is, the preparatory operation action is to enter the base station. If it is analyzed based on the operating parameters that the current clothing processing equipment is in a vibrating state, and the vibration state will enter a non-vibrating state after 20 minutes, it is judged that the state of the clothing processing equipment at this time will affect the ground cleaning equipment from entering the base station. The mobile cleaning device will not execute the action of entering the base station first, and the preparatory operation action will be replaced by waiting outside the base station, performing secondary cleaning on the heavily polluted area, or other work that the mobile cleaning device can perform. After 20 minutes, the clothing processing equipment enters a non-vibrating state, and the mobile cleaning device enters the base station again.

[0034] If the mobile cleaning device is about to complete cleaning and prepare to enter the base station after 10 minutes, the preparatory operation action is to enter the base station. If it is analyzed based on the operating parameters that the current clothing processing equipment is in a non-vibration state, but will enter a vibration state after 5 minutes, and then enter the non-vibration state again after 10 minutes in the vibration state, the mobile cleaning device can choose to give up the remaining cleaning task and enter the base station within 5 minutes, or after completing the cleaning task, wait outside the base station for 5 minutes before entering the base station.

[0035] If the mobile cleaning device is about to complete cleaning and prepare to enter the base station after 10 minutes, the preparatory operation action is to enter the base station. If it is analyzed based on the operating parameters that the current clothing processing equipment is in a non-vibration state and the non-vibration state will continue for 20 minutes, it is determined that the current state of the clothing processing equipment will not affect the floor cleaning equipment from entering the base station, and the mobile cleaning device performs the preparatory operation action.

[0036] The states of a clothing processing device include: off, standby, paused, operating, end-of-run, and faulty states. The operating states further include washing, rinsing, filling, draining, drying, and dehydrating. When the clothing processing device is in the dehydrating or faulty state, significant vibration may occur, and these states are considered vibrating states. When the clothing processing device is off, standby, paused, or end-of-run, significant vibration generally does not occur, and these states are considered non-vibrating states. The non-vibrating state referred to in this embodiment does not simply refer to a state in which no vibration occurs at all, but rather generally refers to a state in which the vibration generated is not noticeable and insufficient to affect the operating state of the floor cleaning device. The vibrating state also generally refers to a state in which the vibration generated is noticeable and affects the normal operation of the floor cleaning device. Different clothing processing devices may have different states. This section summarizes the states that most clothing processing devices may have, and does not list all other states. Because the method of the present invention categorizes these states into those that generate vibration and those that do not, the method is applicable to all types of clothing processing devices regardless of their current state.

[0037] Furthermore, "the ground cleaning equipment performs analysis after receiving the operating parameters" specifically means that the mobile cleaning device can perform real-time analysis on the operating parameters after receiving them, or it can analyze the operating parameters before a certain node, such as before entering or exiting the base station, before completing the cleaning task, within a specified distance from the base station, and within a certain period of time before returning to the base station.

[0038] Further, if Figure 3 As shown, in this embodiment, to confirm whether the operating parameters have been successfully sent, the floor cleaning device will send feedback information to the clothing processing device after receiving the operating parameters. If the clothing processing device receives the feedback information, it means that the parameters have been sent successfully and no further transmission is required. If the clothing processing device does not receive the feedback information, a retransmission mechanism is activated.

[0039] There are two reasons why the clothing processing device did not receive feedback information. One is that the clothing processing device failed to send, and the other is that the floor cleaning device failed to receive. The sending failure may be due to signal abnormality, network abnormality, the distance between the clothing processing device and the floor cleaning device is too large, the signal transmitter failure or the feedback information receiver failure, etc. The receiving failure may be due to signal abnormality, network abnormality, the distance between the clothing processing device and the floor cleaning device is too large, the floor cleaning device is powered off, the signal receiver failure or the feedback information transmitter failure, etc.

[0040] The retransmission mechanism can be implemented by the clothing processing device. Considering that the clothing processing device will shut down after washing, retransmission can also be performed with the help of the cloud or other third-party devices. After establishing a retransmission mechanism by the cloud, the transmission of operating parameters will not always rely on the clothing processing device. The clothing processing device can be shut down after washing. After the clothing processing device is shut down, the operating parameters can be sent to the floor cleaning device via the retransmission mechanism. After the clothing processing device is shut down, the feedback information can also be received by the cloud, and the clothing processing device does not need to cooperate with any other means. The retransmission mechanism can also avoid the problem of operating parameter transmission failure due to the clothing processing device not receiving feedback information.

[0041] If the operation parameters fail to be sent due to signal abnormality or network abnormality, and the floor cleaning device cannot determine the status of the clothing processing device, the floor cleaning device may not execute the action of entering the base station first. After the signal or network is restored and the operation parameters are received, the subsequent actions are determined according to the status of the equipment in the clothing cart.

[0042] Furthermore, in this embodiment, the retransmission mechanism can be: the operating parameters are stored in the cloud, and the cloud sends the operating parameters to the floor cleaning device again. The clothes processing device sends the operating parameters, and the floor cleaning device sends feedback information to the clothes processing device after receiving the operating parameters. If the clothes processing device receives the feedback information, it means that the parameters have been sent successfully, and the clothes processing device does not send them again; if the clothes processing device does not receive the feedback information, the operating parameters are stored in the cloud, and the cloud sends the operating parameters to the floor cleaning device again, and the floor cleaning device sends feedback information to the cloud after receiving the operating parameters. If the cloud receives the feedback information, it means that the operating parameters have been sent successfully. If the cloud does not receive the feedback information, the cloud continues to send the operating parameters to the floor cleaning device until it receives the feedback information. After receiving the feedback information, the cloud no longer sends the operating parameters. At this time, regardless of whether the clothes processing device receives the feedback information from the floor cleaning device, it stops sending the operating parameters; the cloud can send the operating parameters once every period of time.

[0043] Through the cloud, it is possible to avoid failures of the laundry processing device to transmit operating parameters and receive feedback information due to signal anomalies, network anomalies, excessive distance between the laundry processing device and the floor cleaning device, malfunction of the laundry processing device signal transmitter or feedback signal receiver, or shutdown of the floor cleaning device. The laundry processing device can also directly transmit operating parameters to the cloud, which then transmits them to the floor cleaning device. This does not deviate from the basic principles of the present invention and therefore falls within the scope of protection of the present invention.

[0044] A communication connection is established between the clothes processing device and the floor cleaning device, and the communication mode can be one of Bluetooth, wireless network WiFi, mobile cellular network, gateway wireless or wired.

[0045] For example, the clothing processing device and the floor cleaning device are connected by a wireless network. If the clothing processing device encounters signal abnormalities, network abnormalities, and other problems when sending operating parameters to the floor cleaning device, resulting in failure to send the operating parameters, the operating parameters will be sent to the cloud. After the network is normal, the cloud will send the operating parameters to the floor cleaning device.

[0046] For example, the clothing processing device and the floor cleaning device are connected by Bluetooth. If the distance between the clothing processing device and the floor cleaning device exceeds the range of the Bluetooth connection when the clothing processing device sends operating parameters to the floor cleaning device, resulting in failure to send the operating parameters, the operating parameters will be sent to the cloud. Subsequently, when the floor cleaning device moves into the Bluetooth connection range, the cloud will send the operating parameters to the floor cleaning device.

[0047] For example, when the operating parameters are sent, the floor cleaning device is in a powered-off state, and the floor cleaning device cannot receive the operating parameters. Then, the operating parameters are sent to the cloud. After the floor cleaning device is powered on, the cloud sends the operating parameters to the floor cleaning device.

[0048] Furthermore, the same clothing processing equipment may be used multiple times in a day, and each startup will have corresponding operating parameters. The floor cleaning equipment will receive multiple operating parameters in a day. The floor cleaning device must analyze based on the latest operating parameters to accurately determine whether the working state of the clothing processing equipment is in a vibrating state. Therefore, the later operating parameters can overwrite the previous operating parameters, leaving only the latest operating parameters.

[0049] A household appliance includes a clothing processing device and a floor cleaning device. The floor cleaning device includes a mobile cleaning device and a base station. Generally, the clothing processing device is arranged above the floor cleaning device to facilitate the mobile cleaning device to enter and exit the base station. The household appliance also includes a controller, which is configured to execute any of the above methods.

[0050] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
