Washing machine control method and washing machine

Technical field

The invention relates to the field of washing machines, in particular to an internet of things washing machine control method and a washing machine.

Background technique

The Internet of Things is another wave of global informationization following the computer, Internet and mobile communication networks. Since 1999, the concept of the Internet of Things has gradually entered the field of vision. It is considered to be the next trillion-level information technology after the Internet. In recent years, countries around the world are stepping up research on IoT technology.

The development of the Internet of Things is divided into four phases: the first phase is the networking of mainframes and mainframes; the second phase is the connection between desktops and laptops; and the third phase is the interconnection of some mobile devices such as mobile phones; The fourth stage is the rise of the embedded Internet. More applications related to people's daily lives, including washing machines, refrigerators, TVs, microwave ovens, etc., will join the ranks of interconnection and interoperability, eventually forming a global unified "Internet of Things."

The so-called IoT washing machine is a washing machine that can be identified between the washing machine and the object by using the radio frequency automatic identification technology. From the point of view of use, the Internet of Things washing machine can realize the remote control of the washing machine through the sensing device such as computer and intelligent terminal, and can also query the working state of the washing machine in real time, and return the relevant information of the washing machine through the control system. From a technical point of view, it is a new technology that connects various sensors and the existing "Internet" and is an extension of the "Internet" technology. Now, the Internet of Things has begun to change our lifestyle and spending habits.

However, the washing machine is different from other IoT products, and the washing machine has certain safety problems in its work and needs attention. When the washing machine does not have the door switch detection function, if the IoT washing machine is in the remote intelligent terminal control, after the washing machine receives the local or remote pause control command, the washing machine is in the pause phase when the state parameters of the washing machine meet the safety standards, then the washing machine Also controlling the door lock to be turned on, when the smart terminal continues to control the washing machine, since the remote user does not know that the door lock is already open, it may execute some commands that require the door lock to be closed, which may cause remote control. With safety hazards, or for safety, after the door lock is opened, the washing machine controls the remote control function to be turned off, which limits the freedom of remote control, and the remote user's control is easily canceled.

The present invention has been made in view of the above.

detailed description

The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.

In the description of the present invention, it is to be noted that the orientation or positional relationship of the terms "upper", "lower", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, only for the purpose of The invention is not limited by the scope of the invention, and is not intended to be a limitation of the invention.

In the description of the present invention, it should be noted that the terms "mounting" and "connecting" are to be understood broadly, and may be, for example, a fixed connection, a detachable connection, or an integral, unless otherwise explicitly stated and defined. Ground connection; it can be mechanical connection or electrical connection; it can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present invention can be understood in a specific case by those skilled in the art.

Referring to FIG. 1 and FIG. 2, in the present invention, after the washing machine receives the pause or shutdown command, whether to open the door lock needs to be combined with the on/off state information of the remote control function, for example, when the remote control function is turned on, After the washing machine receives the pause command, the door lock is kept locked. Therefore, the washing machine control method of the invention is suitable for the field of the Internet of Things washing machine, and can effectively ensure the safety of the Internet of Things washing machine in remote control and avoid the occurrence of a safety accident.

Preferably, when the remote control is in an open state, the door lock is kept in a locked state after the washing machine receives the pause command; when the washing machine receives the local or remote pause control command, the washing machine is in a pause state as a state parameter of the washing machine. When the safety standard is met, if the washing machine also controls the door lock to open, when the smart terminal continues to control the washing machine, the remote control has a safety hazard because the door lock is already open, even if the washing machine has the function of opening and closing the door lock, because the smart device The user of the terminal does not know whether the door lock of the washing machine is turned on or off. Therefore, if the remote intelligent terminal rashly controls the washing machine, a safety problem arises.

When the remote control is in the off state, the washing machine determines whether the working state parameter of the washing machine is within the safe range after receiving the pause command, and if the judgment result is yes, executing the pause command and controlling the door lock to open, if the result is determined If not, the control door lock is turned on after controlling the working state parameter of the washing machine to within the safe range. When the remote control is off, that is, the washing machine is controlled by the machine, if the washing machine receives the pause command, the user may need to pick up and release the clothes. At this time, when the working state parameter of the washing machine is within the safe range, the control door lock is opened. .

The other is that the washing machine first adjusts or controls the working state until the working state parameter is within the safe range, then executes the pause command and unlocks. Of course, you can also cancel the unlock program and the washing machine will continue to run.

As an embodiment of the present invention, after receiving the shutdown command, the washing machine performs the following steps:

S2, turning off the remote control function, and proceeding to step S3;

Of course, in step S3, if the determination result is no, the washing machine may first control the working state parameter to the safe range, and then unlock and execute the shutdown command.
