detailed description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be construed as limiting the scope of protection of the present invention.

In the home environment, washing machines and clothes dryers are usually placed together on adjacent places such as balcony. When the washing machine finishes washing, you can use the clothes dryer to dry clothes. As disclosed in CN108342886A, CN108342887A, CN108330661A, the clothes dryer 1 includes a main machine 11, a drying rack 12, a drying module, and the like. When the clothes dryer 1 is idle, the clothes rack 12 is raised and gathered under the main machine 11. When the clothes dryer 1 is started, the drying rack 12 is first lowered to a suitable height and stopped to facilitate drying clothes. After the clothes are dried, the (remote control) controller can be used to control the drying rack 12 to rise below the host 11; according to the weather And need to decide whether to turn on the drying module.

If after the washing machine finishes washing and the laundry door is opened to take out the clothes, the clothes dryer can be started, and the clothes hanger 12 on the clothes dryer 1 can be lowered to dry the clothes. This can improve and increase the use of the clothes dryer. User experience in the process.

The invention provides a linkage module, a linkage system and a linkage method of a washing machine and a clothes dryer.

As shown in FIG. 1, a linkage system 10 between a washing machine and a clothes dryer includes a washing machine 5, a clothes dryer 1 and a linkage module 2.

As shown in FIG. 3, the linkage module 2 of the washing machine and the clothes dryer includes a processor 21 and a sensor 22, and the sensor 22 is used to collect the acceleration of the washing machine 5 due to washing vibration and the door angle change when the washing machine door 51 is opened. And transmit the collected data to the processor 21 for processing and analysis. The processor 21 sends a corresponding instruction to control the electric clothes dryer to start according to the collected data. The working mode of the electric clothes dryer may be to perform the action of lowering the clothes rack 12 first, or to activate the lighting first, and then the action of lowering the clothes rack 12 and so on. The circuit diagram of the sensor 22 is shown in FIG. 5.

As shown in FIG. 3, the power module 3 can be used to supply power to the components in the linkage module 2, and a wireless transmission module 6 connected to the processor 21 is added. The wireless transmission module 6 is used to transmit signals to the clothes dryer 1. The control system further controls the lowering action of the drying rack 12. Preferably, the processor 21 may be an MCU or a microcontroller, and a circuit diagram of the processor 21 is shown in FIG. 6. The circuit diagram of the wireless transmission module is shown in Figure 7.

The washing machine 5 generates vibration during the washing process, and the vibration is expressed in the instantaneous acceleration in all directions of the washing machine 5, and the acceleration is collected by the sensor 22.

As shown in FIGS. 1 and 2, the processor 21, the sensor 22, and the wireless transmission module 6 in the linkage module 2 are installed in a housing 20. The linkage module 2 is installed on the outer surface of the door body 51 of the washing machine. 2 can be stuck on the door body 51 of the washing machine 5, the sensor 22 can not only collect the vibration of the washing machine 5 during operation, but also detect the opening angle of the door body 51. The sensor 22 may be multiple, or a 6-axis sensor may be used. The 6-axis sensor detects acceleration in three directions and angular velocity in three directions.

The accelerometer in the sensor 22 is responsible for collecting the acceleration generated by the washing machine 5 due to laundry vibration.

The gyroscope in the sensor 22 is responsible for collecting the door angle change when the door body 51 of the washing machine 5 is opened.

The processor 21 sends an instruction to control the drying rack 12 of the electric clothes dryer to lower and start.

The above-mentioned 6-axis sensor, accelerometer and gyroscope are conventional technical features in the prior art, and are not the key technical content to be protected by the present invention, and the above technical features are common technical knowledge that can be easily obtained by those skilled in the art. Save space The present invention is not repeated here.

In short, the processor 21 in the present invention first detects the acceleration generated by the washing machine 5 due to washing vibration, and then detects the change in the door angle when the door 51 of the washing machine is opened, and the drying rack 12 of the electric clothes dryer is lowered. start up.

As shown in FIG. 4, specifically, the linkage method of the linkage system of the washing machine and the clothes dryer is as follows:

1) The linkage system is in the first sleep state; the sleep state is mainly to save power supply considerations.

2) The sensor 22 detects a change in the acceleration of the washing machine 5, and the linkage system wakes up from the first sleep; the washing vibration of the washing machine 5 will generate acceleration.

3) The sensor 22 detects that the washing machine 5 continues to vibrate and the acceleration value is greater than a preset first threshold value, and considers that the washing process of the washing machine 5 is completed and enters a second sleep state; the first threshold value is greater than or equal to 0.036 m / s ² , which is for It is distinguished from vibrations of washing machines caused by other reasons, such as those caused by personnel collision or heavy vehicles passing by.

4) The sensor 22 detects the acceleration change of the washing machine door 51, and the acceleration of the washing machine door 51 is greater than the second threshold, and the linkage system wakes up from the first sleep; when the door 51 is opened, the door 51 moves from stationary to During the process, the door body 51 will have an acceleration. The second threshold value is set to 0.11 m / s ² , and the second threshold value is greater than the first threshold value, because the acceleration generated by the door body 51 during the opening process will be greater than that of the washing machine 5 vibration. The resulting acceleration.

5) When the sensor 22 detects that the angle change of the door body 51 is greater than 45 degrees, the processor 21 sends an instruction to control the drying rack 12 of the clothes dryer to descend. The angle change of the door body 51 may preferably be greater than 55 degrees, and the opening width of the door body 51 required to normally open the door body 51 to pick up clothes.

It should be noted that the above-mentioned continuous vibration is defined as the cumulative vibration of the washing machine for more than 1 minute in 4 minutes. Depending on the model or function, the washing machine has different working modes, such as washing mode, dehydration mode or drying mode. The setting time of the mode is more than 4 minutes. In the working mode of a washing machine, the cumulative vibration time is more than 1 minute, and the acceleration is greater than the first threshold. Although the washing machine may be in the laundry mode, the linkage system can consider the laundry The process is complete, waiting for the next door opening action.
