Description

Technical Field

[0001] The present invention relates to the field of household appliances, and specifically provides an all-in-one cleaning machine and a control method thereof. Background Art

[0002] There are more and more types of cleaning equipment available, and their functions are becoming more and more comprehensive. For example, 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, 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 set up 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 consume more funds.

[0003] In order to alleviate this situation, you can choose to use integrated home appliances, 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 work 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 water pipes can be shared, then the wall space can be further saved and the quality of life of the user can be improved.

[0004] In actual application, the floor cleaning device and the clothes processing device work independently. Since the two devices share a common space, when the floor cleaning device and the clothes processing device need to work at the same time, the operation of one device may affect the operation performance of the other device, affecting the user experience. For example, when the clothes processing device is performing a dehydration process, the clothes processing device will cause the entire cleaning machine to vibrate, which will affect the mobile cleaning device from entering and exiting the base station, or affect the normal charging of the mobile cleaning device.

[0005] In order to solve this problem, the prior art 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, so as to 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 further affect the normal operation of the clothing processing equipment and the floor cleaning equipment.

[0006] Accordingly, the art needs a new all-in-one cleaning machine to solve the above problems. Summary of the invention

[0008] In the above specific embodiment with the integrated cleaning machine, the integrated cleaning machine further comprises: a distance sensor, which is arranged on the mobile cleaning device and is used to measure the distance between the mobile cleaning device and the clothes processing equipment.

[0009] A control method for an all-in-one cleaning machine, the all-in-one cleaning machine adopts any of the above-mentioned all-in-one cleaning machines, and the control method comprises the following steps: S101: a mobile cleaning device works; S102: judging whether to turn on a sound recognition device according to the working state of the mobile cleaning device; S103: the sound recognition device collects and analyzes an external audio signal to obtain an analysis result; S104: deciding on a subsequent execution action of the mobile cleaning device according to the analysis result.

[0010] In the specific implementation of the control method of the above-mentioned cleaning machine, "determining whether to turn on the sound recognition device according to the working state of the mobile cleaning device" is specifically: determining whether the mobile cleaning device is performing cleaning work; if so, the mobile cleaning device is in a working state, and the sound recognition device is not turned on; and / or if not, executing the next step; determining through a distance sensor whether the distance between the mobile cleaning device and the clothing processing equipment is less than a preset threshold; if not, the mobile cleaning device is in a working state, and the sound recognition device is not turned on; and / or if yes, the mobile cleaning device is in a non-working state, and the sound recognition device is turned on.

[0012] In a specific implementation of the control method of the above-mentioned all-in-one cleaning machine, subsequent execution actions include: waiting, continuing cleaning and entering the base station.

[0013] In the specific implementation of the above-mentioned control method with a cleaning machine, "deciding the subsequent execution action of the mobile cleaning device based on the analysis results" is specifically: if the clothing processing equipment is in a non-vibrating state, the mobile cleaning device enters the base station; and / or if the clothing processing equipment is in a vibrating state, the mobile cleaning device does not enter the base station.

[0014] In a specific implementation of the above-mentioned control method with a cleaning machine, the non-vibration state of the clothing processing device includes: washing state, rinsing state, water filling state, drainage state, drying state, standby state, shutdown state and pause state.

[0016] In a specific implementation of the control method of the above-mentioned all-in-one cleaning machine, when the sound recognition device is working, the mobile cleaning device stops moving.

[0017] In the case of adopting the above technical solution, the present invention sets a sound recognition device on the mobile cleaning device, collects the sound of the current operating state of the clothing processing equipment through the sound recognition device, and analyzes it according to the collected results to identify the working state of the clothing processing equipment, and then decides the subsequent actions of the mobile cleaning device according to the working state of the clothing processing equipment.

[0021] 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 will affect the normal operation of the mobile cleaning device during use.

[0022] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the relevant devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, ordinal numbers such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Furthermore, in order to more clearly demonstrate the core technical solution of the present invention, the description of the known structures of the clothing processing equipment and the floor cleaning equipment is omitted in the following description. However, this omission is only for the convenience of description and does not mean that the clothing processing equipment and the floor cleaning equipment can be without these structures.

[0025] The present invention proposes an all-in-one cleaning machine, comprising: a clothes processing device and a floor cleaning device, the floor cleaning device comprising a mobile cleaning device and a base station, the mobile cleaning device entering and exiting the base station; a sound recognition device is provided on the mobile cleaning device, for recognizing and analyzing the sound of the clothes processing device. The sound recognition device can analyze according to different sounds, and the sound wavelengths and frequencies emitted by different people and different devices are different, and people and animals can be distinguished according to the voiceprint, and then their signals can be filtered and processed.

[0026] Before the mobile cleaning device enters the base station, the sound signal is collected by the sound recognition device, and the sound signal is filtered and analyzed to find the sound signal of the clothing processing equipment. The corresponding working state of the clothing processing equipment is determined based on the sound signal of the clothing processing equipment, and then whether it is convenient for the mobile cleaning device to enter in this working state is determined based on the working state. If it is convenient for the mobile cleaning device to enter, the mobile cleaning device enters the base station; if it is not convenient for the mobile cleaning device to enter, the mobile cleaning device waits or continues to clean.

[0027] In this embodiment, in order to solve the problem in the prior art that network interruption will affect the coordination between the clothing processing equipment and the floor cleaning equipment, a sound recognition device is set on the mobile cleaning device. The sound of the current operating state of the clothing processing equipment is collected by the sound recognition device, and the working state of the clothing processing equipment is identified based on the collected results. Then, the subsequent actions of the mobile cleaning device are decided based on the working state of the clothing processing equipment. During the whole process, there is no need to maintain communication between the clothing processing equipment and the floor cleaning equipment, so there will be no problem of network interruption affecting the normal operation of both parties. The mobile cleaning device can turn on the sound recognition device at any time to analyze the current working state of the clothing processing equipment. In addition, the present invention only requires a small improvement to the mobile cleaning device, and does not require too many changes to the original structure or system of the mobile cleaning device, which is easy to implement.

[0028] Furthermore, since there may be various noises in the house, in order to more accurately collect the sound signals of the clothing processing equipment, the cleaning machine also includes: a distance sensor, which is arranged on the mobile cleaning device and is used to measure the distance between the mobile cleaning device and the clothing processing equipment. Before collecting the sound signal, the mobile cleaning device first uses the distance sensor to determine whether the distance between the mobile cleaning device and the clothing processing equipment is less than a preset threshold. If it is less than the preset threshold, it collects the sound signal. If it is greater than the preset threshold, it means that the distance between the two is far and is not suitable for collection. The mobile cleaning device can continue to move toward the clothing processing equipment until the distance is less than the preset threshold before collecting the sound signal, so as to avoid excessive noise or too small sound of the clothing processing equipment, which may lead to inaccurate analysis results. In addition, the mobile cleaning device can also use the distance sensor to determine the distance relationship between it and the obstacle to achieve the obstacle avoidance function.

[0029] The all-in-one cleaning machine also includes a control system. The operation and analysis of the sound recognition device and the distance sensor are controlled by the control system, and the movement of the mobile cleaning device is also decided and controlled by the control system.

[0030] A control method for a cleaning machine, wherein the cleaning machine adopts any of the above-mentioned cleaning machines, and since the mobile cleaning device also makes sounds when working, in order to improve the accuracy of the sound recognition device, the mobile cleaning device needs to cooperate, and the sound recognition device is turned on under the condition that the mobile cleaning device does not generate a large noise that affects the accuracy of the analysis result. Figure 1As shown, the control method includes the following steps: S101: the mobile cleaning device works; S102: according to the working state of the mobile cleaning device, it is determined whether to turn on the sound recognition device; S103: the sound recognition device collects and analyzes the external audio signal to obtain the analysis result; S104: according to the analysis result, the subsequent execution action of the mobile cleaning device is determined. The subsequent execution actions include: the mobile cleaning device waits in place, continues to clean and enters the base station, and can also perform other tasks, such as the mobile cleaning device detects the environment at home to improve the map, finds the location of family members and gives language prompts, monitors the situation of the elderly at home, etc.

[0031] Further, "determine whether to turn on the sound recognition device according to the working state of the mobile cleaning device" specifically means: determine whether the mobile cleaning device is performing cleaning work; if so, the mobile cleaning device is in working state and the sound recognition device is not turned on; and / or if not, execute the next step; then determine through the distance sensor whether the distance between the mobile cleaning device and the clothing processing device is less than a preset threshold; if not, the mobile cleaning device is in working state and the sound recognition device is not turned on; and / or if yes, the mobile cleaning device is in non-working state and the sound recognition device is turned on. In this embodiment, for the convenience of classification, the situation where the mobile cleaning device is too far away from the clothing processing device is also classified as a working state.

[0032] In this embodiment, in order to avoid the presence of large noise in the collected sound or the sound of the clothing processing device being too small to affect the accuracy of the analysis result, the sound recognition device is turned on when the mobile cleaning device is not cleaning and the distance between the mobile cleaning device and the clothing processing device is less than a preset threshold. For example, when the mobile cleaning device is in a state of sweeping or mopping the floor, the sound recognition device is not turned on; when the mobile cleaning device is not cleaning, the distance between it and the clothing processing device is determined by the distance sensor, and the sound recognition device is turned on when it is less than a preset threshold, thereby avoiding the erroneous operation caused by the interference of external and self-sounds on the recognition effect of the sound recognition device during the working process, and improving the accuracy of the mobile cleaning device in executing the action.

[0033] In this embodiment, two conditions are defined, namely, the mobile cleaning device is not cleaning and the distance is less than a preset threshold. In actual application, one of the limiting conditions can be selected according to the situation. For example, if no one is at home, all electrical appliances are on standby, and there is no external noise, then only the condition that the mobile cleaning device is not cleaning can be satisfied.

[0034] To further improve the accuracy of the analysis results, the mobile cleaning device can be stopped when the sound recognition device is working, or although the mobile cleaning device continues to move, the sound recognition module can filter the noise generated by the mobile cleaning device to avoid affecting the accuracy of the results.

[0035] Furthermore, "the sound recognition device collects and analyzes the external audio signal to obtain the analysis result" is specifically: the sound recognition device collects and analyzes the external audio signal to determine the working state of the clothing processing device. In this embodiment, the working state of the clothing processing device is divided into a vibration state and a non-vibration state according to whether the vibration generated by the clothing processing device in the current state will affect the mobile cleaning device entering and exiting the base station. The vibration state is a state that will affect the mobile cleaning device entering and exiting the base station, and the non-vibration state is a state that will not affect the mobile cleaning device entering and exiting the base station; when the clothing processing device is in a vibration state, the vibration generated is larger, and accordingly, the sound generated will also be louder; when the clothing processing device is in a non-vibration state, the vibration generated is smaller, and accordingly, the sound generated will also be smaller.

[0036] The clothing treatment device is used to clean clothes, and can be one of a drum washing machine, a pulsator washing machine, a stirring washing machine, a clothes dryer, a shoe washing machine, and a clothing care machine. Other laundry equipment can also be used in this solution; the floor cleaning equipment can be one of a sweeping robot, a mopping robot, a sweeping and mopping robot, a sweeping and wiping robot, and a floor scrubber. Generally, the states of the clothing treatment device include: shutdown state, standby state, pause state, running state, end of operation state, and fault state, etc. The running state includes washing state, rinsing state, water filling state, drainage state, drying state, and dehydration state, etc. The vibrations generated by the clothing treatment device in different states are different. For example, the clothing treatment device does not wash in the standby state, so it will not vibrate and will not make any sound; in the washing state or the rinsing state, the motor speed of the clothing treatment device is lower than 100RPM, and the sound recognition is high, including the sound of laundry falling; in the dehydration state, the motor of the clothing treatment device rotates at a high speed. Depending on the model, the speed is generally between 400-1400RPM, which is significantly higher than other states, so the vibration and sound generated are also larger and more obvious.

[0037] According to the vibration size, the non-vibration state of the clothing processing equipment includes: washing state, rinsing state, water filling state, drainage state, drying state, standby state, shutdown state and pause state. The vibration state of the clothing processing equipment includes: dehydration state and fault state. The non-vibration state mentioned in this embodiment does not only refer to the state where no vibration is generated, but generally refers to the state where the vibration generated is not obvious and is not enough to affect the working state of the floor cleaning device. The vibration state also generally refers to the working state where the vibration generated is relatively obvious and will affect the normal operation of the floor cleaning device. Different clothing processing equipment will have different states. Here, the states that most clothing processing equipment will have are summarized, and other states will not be listed one by one. Because the method in the present invention divides these states into states that will generate vibration and states that will not generate vibration, no matter what type of clothing processing equipment currently has what state, this method is applicable.

[0038] The audio signals generated by the clothing processing equipment in different operating states are also different. The corresponding feature information can be obtained through laboratory modeling training, and its module can be pre-set into the sound recognition device to realize working status judgment, so as to make more accurate judgments and facilitate planning of subsequent execution actions of the mobile cleaning device.

[0039] Furthermore, "deciding the subsequent execution action of the mobile cleaning device based on the analysis results" is specifically: if the clothing processing equipment is in a non-vibrating state, it means that the vibration generated by the clothing processing equipment will not affect the mobile cleaning device from entering the base station, then the mobile cleaning device is controlled to enter the base station; and / or if the clothing processing equipment is in a vibrating state, it means that the vibration generated by the clothing processing equipment will affect the mobile cleaning device from entering the base station, then the mobile cleaning device does not enter the base station, and can continue to wait or enter other areas to be cleaned or heavily contaminated areas for secondary cleaning. Whether cleaning can still be performed can be considered in combination with the remaining power of the current mobile cleaning device. If there is still enough power and one cleaning can be completed, the mobile cleaning device can be controlled to clean. After the cleaning is completed, the mobile cleaning device moves to a position where the distance between it and the clothing processing equipment is less than a preset threshold, and then the sound recognition device is activated to detect the state of the clothing processing equipment; if the power is not enough to complete one cleaning, it can wait in place and enter the base station when the clothing processing equipment enters a non-vibrating state.

[0040] During the waiting process, in order to reduce the waiting time of the mobile cleaning device, the sound recognition device can be turned on once at a certain interval. The time interval is not fixed and can be three minutes, five minutes or ten minutes. It can also be adjusted according to the dehydration time of the actual clothing processing equipment. For example: the sound recognition device is turned on, the sound signal is collected and analyzed, and the current state of the clothing processing equipment is the washing state, and the washing state is a non-vibration state, so the mobile cleaning device can be controlled to enter the base station; if the sound recognition device is turned on, the sound signal is collected and analyzed, and the current state of the clothing processing equipment is the dehydration state, and the dehydration state is a vibration state, the mobile cleaning device can be controlled to wait or continue cleaning. If the power of the mobile cleaning device is not enough to perform the cleaning task, the mobile cleaning device is controlled to wait, and the sound recognition device is turned on every five minutes. When it is detected that the clothing processing equipment enters a non-vibration state, the mobile cleaning device is controlled to enter the base station.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
