Detailed Description
In order to make the embodiments, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the embodiments are some, but not all embodiments of the present invention. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Referring to fig. 1, fig. 1 is a main flowchart of a washing machine safety detection method of the present invention. As shown in fig. 1, the security detection method of the present invention includes the following steps: s110, in the dewatering stage of the washing machine, when the cover of the washing machine is detected to be switched from a closed state to an open state, first state information of the washing tub is detected; s120, when the washing machine cover is detected to be switched back to the closed state from the open state, second state information of the washing tub is detected again; and S130, comparing the second state information with the first state information, and selectively sending out alarm prompt information according to the comparison result. Through the scheme, in the dewatering stage of the washing machine, if the cover of the washing machine is opened (namely the cover of the washing machine is opened and then closed), and the cover of the washing machine is opened and closed through remote control (such as remote server control or user terminal remote control, the cover of the washing machine can also be opened due to other reasons), once an organism or a non-organism enters the washing tub in the process of opening and closing the cover of the washing machine, the organism or the non-organism can be judged through the comparison result of the second state information and the first state information, and then the alarm prompt information is sent to remind the user, so that the danger caused by the fact that the washing tub continues to operate after the organism or the non-organism enters the washing tub is prevented. That is, the scheme of the invention can eliminate the potential danger caused by the opening of the cover of the washing machine during the operation process of the washing machine.
As an example, the first state information is a first weight of the tub, and the second state information is a second weight of the washing machine. That is, in the dewatering stage of the washing machine, once the washing machine cover is opened, the current weight of the washing tub is detected, and after the washing machine cover is closed again, the weight of the washing tub is detected again. Then, the weight of the washing tub detected twice is compared to judge whether a living or non-living organism enters the washing tub. More specifically, when the second weight of the washing tub exceeds the first weight and the first threshold (the skilled person can flexibly set the first threshold to select a suitable accuracy), it indicates that foreign matter has entered the washing tub, and an alarm prompt message is issued at this time, otherwise, the alarm prompt message is not issued. For example, if the cover of the washing machine is opened during the operation of the washing machine, and the user is not beside the washing machine, once the pet enters the washing tub, the cover of the washing machine is closed, the weight of the washing tub will be increased significantly, and an alarm prompt message is sent to prompt the user for the life safety of the pet
As another example, the first state information is a first weight of the tub, and the second state information is a second weight of the washing machine. Since the foreign matter enters the washing tub and then further increases the shaking amplitude of the washing tub, when the second weight of the washing tub exceeds the first weight and the first threshold (the first threshold can be flexibly set by a person skilled in the art to select a proper precision), the shaking amplitude of the washing tub is detected, and when the shaking amplitude of the washing tub exceeds the second threshold (the second threshold can be flexibly set by a person skilled in the art to select a proper precision), an alarm prompt message is sent. In the embodiment, on the basis of comparing the first weight and the second weight, the accuracy of judgment is improved by combining the shaking amplitude.
As another example, the first state information is a first weight of the tub, and the second state information is a second weight of the washing machine. When the second weight of the washing tub exceeds the first weight by a first threshold value (the skilled person can flexibly set the first threshold value to select a suitable accuracy), information detected by the light sensor in the washing tub is acquired. If the information detected by the light sensor is light transmission information, no alarm prompt information is sent out; and if the information detected by the light sensor is opaque information, sending out alarm prompt information. Specifically, during the dewatering stage of the washing machine, the washing tub is empty of water, and the clothes are generally in a position close to the wall of the washing tub, and at this time, in the case that the light sensor is installed in the washing tub, once the light sensor detects opaque information, it indicates that foreign matter (such as pets) enters the washing tub, and at this time, an alarm prompt message is sent out. In this embodiment, the accuracy of the determination is improved by combining the data detected by the light sensor in the washing tub based on the comparison between the first weight and the second weight.
In the step S130, the alarm prompt message may be a peak sound, a voice prompt or a light prompt sent by the washing machine; or a beep, voice prompt or short message prompt received by the user terminal. For example, after it is determined that foreign matter enters the washing tub, the washing machine may emit a buzzer sound, a voice prompt, or a flashing light to remind the user, or may send a short message prompt, a buzzer sound prompt, or a voice prompt to a mobile phone of the user to remind the user. The skilled person may choose any suitable way of issuing an alert prompt to prompt the user.
The present invention also provides a washing machine including a controller configured to perform the above-described washing machine safety detection method.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
