Description

Technical Field

[0001] This invention relates to the field of smart home appliance technology, specifically providing a method, device, washing machine, and medium for intelligently controlling the door opening angle. Background Technology

[0002] If clothes are not removed from the washing machine and dried promptly after washing, they can easily develop unpleasant odors. To address this issue, some front-loading washing machines automatically open the door after the wash cycle to allow air circulation within the drum, preventing odors and making it easier for users to load and unload clothes. However, when the washing machine automatically opens the door, it often results in clothes falling out of the drum and onto the floor due to the door opening too wide. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the laundry falls from the washing tub to the ground due to the excessive opening of the door in existing washing machines.

[0004] In a first aspect, the present invention provides a method for intelligently controlling the opening angle of a door, comprising the following steps:

[0005] Obtain environmental information around the washing machine door, wherein the environmental information includes at least personnel information and / or container information within a preset range of the door;

[0006] The opening angle of the washing machine door is determined based on the environmental information surrounding the door.

[0007] The hatch is opened according to the determined opening angle.

[0008] Optionally, the environmental information surrounding the hatch includes at least one of the following: whether there is a person or container within a preset range of the hatch, the location of the person or container, the type of the container, the cleanliness of the container, and the purpose of the container.

[0009] Determining the opening angle of the washing machine based on the environmental information surrounding the door includes determining the opening angle of the washing machine based on at least one of the aforementioned environmental information surrounding the door.

[0010] Optionally, determining the opening angle of the washing machine door based on the surrounding environmental information includes determining whether there is anyone within a preset range from the door; if so, the door opens at a larger angle; otherwise, it opens at a smaller angle.

[0011] Specifically, when the door opens at a large angle, the opening angle exceeds the first threshold.

[0012] When the door is opened at a small angle, the opening angle is less than or equal to the second threshold, and the first threshold is greater than the second threshold.

[0013] Optionally, determining the opening angle of the washing machine door based on the surrounding environmental information includes determining whether there is a person within a preset range from the door. If so, it further determines whether the person is within the door opening travel range. If the person is within the door opening travel range, the door is opened at a small angle; if the person is not within the door opening travel range, the door is opened at a large angle.

[0014] Among them, when the door is opened at a large angle, the opening angle is greater than the third threshold;

[0015] When the door is opened at a small angle, the opening angle is less than or equal to the fourth threshold, and the third threshold is greater than the fourth threshold.

[0016] Optionally, if it is determined that there is no one within a preset range of the door, then it is further detected whether a container is placed in front of the washing machine door. If a container is placed in front of the washing machine door, then the door is opened at a large angle; otherwise, the door is opened at a small angle.

[0017] Among them, when the door is opened at a large angle, the opening angle is greater than the fifth threshold.

[0018] When the door is opened at a small angle, the opening angle is less than or equal to the sixth threshold, and the fifth threshold is greater than the sixth threshold.

[0019] Optionally, determining the opening angle of the washing machine door based on the surrounding environmental information includes:

[0020] Determine whether a container is placed in front of the washing machine door. If a container is placed in front of the washing machine door, determine the opening angle of the washing machine door based on at least one of the following: the cleanliness of the container, the distance and orientation of the container from the washing machine, and the purpose of the container.

[0021] Optionally, if a container is placed in front of the washing machine door, the cleanliness of the container is further determined. If it is clean, the door is opened at a large angle; otherwise, the door is opened at a small angle.

[0022] or,

[0023] If a container is placed in front of the washing machine door, the distance and orientation of the container to the washing machine are further determined to determine whether the container is the target laundry container. If so, the door is opened at a large angle; otherwise, the door is opened at a small angle.

[0024] or,

[0025] If a container is placed in front of the washing machine door, it is further determined whether the container is a clothes container. If so, the door is opened at a large angle; otherwise, the door is opened at a small angle.

[0026] Among them, when the door is opened at a large angle, the opening angle is greater than the seventh threshold;

[0027] When the door is opened at a small angle, the opening angle is less than or equal to the eighth threshold, and the seventh threshold is greater than the eighth threshold.

[0028] In a second aspect, the present invention provides a device for intelligently controlling the opening angle of a door, comprising:

[0029] A surrounding environment information acquisition module is used to acquire surrounding environment information of the washing machine door, wherein the surrounding environment information includes at least personnel information and / or container information within a preset range of the door;

[0030] The door opening angle determination module is used to determine the opening angle of the washing machine door based on the environmental information around the door.

[0031] The door opening angle control module is used to control the opening of the hatch based on the determined door opening angle.

[0032] In a third aspect, the present invention provides a washing machine, including a memory and a processor, wherein the memory stores machine-executable instructions, and when the machine-executable instructions are executed by the processor, the device enables the intelligent control of the door opening angle as described in any one aspect.

[0033] In a fourth aspect, the present invention provides a computer storage medium storing a computer program, which, when executed, enables the method for intelligently controlling the door opening angle as described in any one of the first aspects.

[0034] By adopting the above technical solution, the present invention can control the opening angle of the washing machine door according to the environmental information around the door, which can avoid odors inside the machine after washing, prevent injury to users when opening the door, and avoid soiling clothes. It achieves a balance of all three, providing functionality while also showing care for users and improving user satisfaction. Attached Figure Description

[0045] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0047] This invention primarily addresses the problem of laundry falling from the washing tub to the ground due to excessively large door opening in existing washing machines.

[0048] In a first aspect, the present invention provides a method for intelligently controlling the door opening angle, such as... Figure 1 As shown, it mainly includes the following steps:

[0049] S1: Obtain environmental information around the washing machine door, wherein the environmental information includes at least personnel information and / or container information within a preset range of the door;

[0050] S2: Determine the opening angle of the washing machine door based on the surrounding environmental information of the door;

[0051] S3: Control the opening of the hatch according to the determined opening angle.

[0052] A first embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 2 As shown,

[0053] When the washing machine finishes washing, it analyzes the environment around the washing machine door using its built-in camera or sensors. First, it acquires information about the surrounding environment using the camera or sensors. Then, it determines the presence of people within a preset range of the door based on this information, and determines the door opening angle accordingly. Finally, it controls the door to open based on the determined opening angle. For example, when the washing machine finishes washing, the camera acquires image information about the environment around the door. Analyzing this image information can determine if there are people within 1 meter of the door. If someone is detected within 1 meter, the washing machine automatically opens the door at a large angle. The specific opening angle can be preset in the washing machine through parameter settings, for example, a large angle greater than 120 degrees. Preferably, the user is alerted by sound or voice before the door opens. If no one is detected within 1 meter, the washing machine automatically opens the door at a small angle. The specific opening angle can be preset in the washing machine via parameter settings; for example, a small angle of less than 20 degrees can be set. Preferably, after the washing machine opens the door, it will remind the user through sound or voice prompts, notifying the user that the door is open and thus reminding the user to hang the washed clothes to dry as soon as possible.

[0054] A second embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 3 As shown,

[0055] This embodiment and Figure 2 The difference in the first embodiment shown is that when it is determined that there is someone within a preset range of the washing machine door based on the environmental information around the washing machine door, it is further determined whether the person is within the range of the washing machine door's opening stroke, and the opening angle of the washing machine door is determined based on the determination result.

[0056] For example, by analyzing the acquired image information and determining that there is someone within 1 meter of the washing machine door, the washing machine further determines whether the person is within the door's opening range. If the person is within the door's opening range, to avoid injury such as bumping into them when the door opens, the washing machine automatically opens the door at a small angle. If the person is not within the door's opening range, the washing machine automatically opens the door at a large angle.

[0057] The remaining steps of this embodiment are the same as those in this embodiment. Figure 2 The corresponding processing procedure in the first embodiment of the present invention is the same, and will not be repeated here.

[0058] A third embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 4 As shown,

[0059] When the washing machine finishes its cycle, it analyzes the environment around the washing machine door using its built-in camera. First, the camera captures information about the surrounding environment. Then, it determines whether a container is placed in front of the door and adjusts the door opening angle accordingly. Finally, it controls the door to open based on the determined opening angle. For example, when the washing machine finishes its cycle, the camera captures images of the environment around the door and analyzes them to determine if a container is placed in front of the door. If a container is detected, the washing machine automatically opens the door at a large angle. The specific opening angle can be preset in the washing machine settings, for example, a large angle greater than 120 degrees. If no container is detected, the washing machine automatically opens the door at a small angle. The specific opening angle can also be preset in the washing machine settings, for example, a small angle less than 20 degrees. Preferably, the user is reminded by sound or voice playback after the washing machine door is opened, so as to remind the user to hang the washed clothes to dry as soon as possible.

[0060] The fourth embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 5 As shown,

[0061] This embodiment and Figure 4 The difference in the third embodiment is that when it is determined that there is a container placed in front of the washing machine door based on the environmental information around the washing machine door, the washing machine sends the acquired environmental information around the door as an image to the server connected to it through the washing machine's IoT module. The server performs image analysis on the uploaded image information to further confirm the cleanliness of the container, and determines the opening angle of the washing machine door based on the judgment result.

[0062] For example, after analyzing the acquired image information and determining that a container is placed in front of the washing machine door, the washing machine sends the acquired environmental information around the door as an image through its IoT module to a connected server. The server then analyzes the uploaded image information, specifically determining the cleanliness of the container based on its color, brightness, and other information. If the cleanliness of the container is determined to be below a preset cleanliness threshold, the washing machine automatically opens the door at a small angle to prevent clothes from falling into the unclean container when the door is opened. If the cleanliness of the container is determined to be above the preset cleanliness threshold, the washing machine automatically opens the door at a larger angle.

[0063] The remaining steps of this embodiment are the same as those in this embodiment. Figure 4 The corresponding processing procedure in the third embodiment of the present invention shown is the same, and will not be repeated here.

[0064] The fifth embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 6 As shown,

[0065] This embodiment and Figure 4 The difference in the third embodiment is that when it is determined that there is a container placed in front of the washing machine door based on the environmental information around the washing machine door, the washing machine sends the acquired environmental information around the door as an image to the server connected to it through the washing machine's IoT module. The server performs image analysis on the uploaded image information to further confirm whether the container is the target clothes container, and determines the opening angle of the washing machine door based on the judgment result.

[0066] For example, after analyzing the acquired image information and determining that a container is placed in front of the washing machine door, the washing machine sends the acquired information about the surrounding environment of the door as an image through its IoT module to a connected server. The server then analyzes the uploaded image information, specifically determining whether the container is the target container for holding clothes based on information such as the distance and orientation of the container relative to the washing machine in the uploaded image. For example, if the container is some distance from the washing machine door, or if the container is not placed directly in front of the door, it may not be the target container. If the container is determined not to be the target container, the washing machine automatically opens the door at a small angle to prevent clothes from falling to the ground when the door is opened. If the container is determined to be the target container, the washing machine automatically opens the door at a larger angle.

[0067] The remaining steps of this embodiment are the same as those in this embodiment. Figure 4 The corresponding processing procedure in the third embodiment of the present invention shown is the same, and will not be repeated here.

[0068] The sixth embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 7 As shown,

[0069] This embodiment and Figure 4 The difference in the third embodiment is that, after determining that there is a container placed in front of the washing machine door based on the environmental information around the washing machine door, the washing machine sends the acquired environmental information around the door as an image to the server connected to it through the washing machine's IoT module. The server performs image analysis on the uploaded image information to further confirm whether the container is a clothes container, and determines the opening angle of the washing machine door based on the judgment result.

[0070] For example, after analyzing the acquired image information and determining that a container is placed in front of the washing machine door, the washing machine sends the acquired information about the surrounding environment as an image through its IoT module to a connected server. The server then analyzes the uploaded image, specifically comparing the container image with pre-saved historical container images to determine if the container is a proper garment container. For instance, if the image comparison reveals that the container has never been used for garments, it may not be a garment container but rather a basin for other purposes such as a foot bath, mop basin, or dishcloth basin. If the container is determined not to be a garment container, the washing machine automatically opens the door at a small angle to prevent clothes from falling into a non-garment container when the door is opened. If the container is determined to be a garment container, the washing machine automatically opens the door at a large angle.

[0071] The remaining steps of this embodiment are the same as those in this embodiment. Figure 4 The corresponding processing procedure in the third embodiment of the present invention shown is the same, and will not be repeated here.

[0072] The seventh embodiment of the intelligent door opening angle control method of the present invention, as follows: Figure 8 As shown,

[0073] This invention can also comprehensively analyze and judge personnel and container information within a preset range of the washing machine door, determine the opening angle of the washing machine door based on the judgment result, and control the door to open according to the determined opening angle. The container information may include at least the container's cleanliness, purpose, and distance from the washing machine. Specifically,

[0074] When the washing machine finishes washing, its built-in camera analyzes the environment around the washing machine door. First, the camera acquires information about the surrounding environment, including information about people and containers within a preset range of the door. Then, it determines the location of people within that range, whether containers are placed in front of the door, and the cleanliness of those containers. Based on this determination, it sets the door opening angle. Finally, it controls the door to open according to the determined opening angle. For example, when the washing machine finishes washing, the camera captures images of the environment around the door. Analyzing these images can determine if there is anyone within 1 meter of the door. If no one is within 1 meter, the washing machine automatically opens the door at a small angle. If someone is within 1 meter, it further checks if the person is within the door's opening range. If so, the washing machine automatically opens the door at a small angle. If it is determined that the person is not within the opening range of the washing machine door, the machine continues to check if a container is placed in front of the door. If no container is found, the washing machine automatically opens the door at a small angle. If a container is found in front of the door, the machine continues to check the cleanliness of the container. If the cleanliness of the container is lower than a preset cleanliness threshold, the machine automatically opens the door at a small angle. If the cleanliness of the container is higher than a preset cleanliness threshold, the machine continues to check if the container is a laundry container. If the container is not a laundry container, the machine automatically opens the door at a small angle. If the container is a laundry container, the machine continues to check if it is the target laundry container. If the container is not the target laundry container, the machine automatically opens the door at a small angle. If the washing machine determines that the container placed in front of the washing machine door is the target laundry container, the washing machine will automatically open the door at a large angle.

[0075] Although attached Figure 8 The container information determination shown involves sequentially judging container cleanliness, whether the container is a garment container, and whether it is the target garment container. However, in actual implementation, the container information determination steps are not limited to the attached steps. Figure 8 The judgment steps in the illustrated embodiment can be adjusted and selected by those skilled in the art according to actual needs. For example, the judgment step of the target garment container or the container cleanliness judgment can be omitted; or, for example, it can be judged first whether the container is a garment container and / or whether it is the target garment container, and then the cleanliness of the container can be judged.

[0076] The technical means and other steps used in this embodiment are the same as those described in the above embodiments of the present invention, and will not be repeated here.
