Description

[0001] The present invention relates to a vibration notification device,

More particularly, the present invention relates to an operation notification device for attaching to a vibration generating device such as a washing machine and confirming information on the operation state of the vibration generating device through a user terminal, And a notification method.

2. Description of the Related Art Generally, a vibration generator including a washing machine, a mixer, and the like is provided with a display for displaying an operating state and a speaker for outputting sound according to the operating state.

When a predetermined operation mode is input from the user, the conventional vibration generating device displays the operation mode, the current operation state and the operation completion state through the display, or responds to the operation mode, the current operation state and the operation completion state And outputs the sound or the recorded voice.

For example, in the case of a washing machine, when the user sets the washing mode, information including the washing mode and the time remaining until the washing is displayed on the display provided on one side of the washing machine, and while the washing machine is operating, And displays the progress of the washing operation. When the washing operation is completed, the washing operation completion status is displayed and a predetermined sound is output to inform the user of the completion of the washing operation.

On the other hand, the display provided in the conventional vibration generating device can provide predetermined information only when it is in the field of view of the user, and can transmit predetermined information only when the user is at a predetermined distance from which sound can be heard There is a problem that transmission of information is restricted depending on the location of the user.

In addition, a method of manufacturing and supplying a vibration generating device provided with a communication module for transmitting predetermined information to a user terminal carried by the user may be proposed, but in this case, the user must purchase or replace the vibration generating device itself There is a fear that the purchase cost may be greatly increased due to the function of the vibration generating device, so that there is a problem that the cost burden of the user greatly increases.

The vibration sensing unit 110 may be an acceleration sensor, for example, a piezoelectric acceleration sensor, a coaxial acceleration sensor, a servo acceleration sensor, or a strain gage type acceleration sensor.

The determination unit 120 determines the operation state of the vibration generator based on the detection result of the vibration detector 110. For example, the judging unit 120 may be provided to judge whether the washing machine 10 starts to be laundered or not, based on the detection result of the vibration detecting unit 110.

To this end, at least one determination criterion for determining the operation state of the vibration generator in accordance with the vibration sensed by the vibration sensing unit 110 may be preset in the determination unit 120, May be set respectively in accordance with the vibration characteristics of the washing machine 10 or the mixer, and may include a threshold value for judgment set as an acceleration rms value of vibration.
