This can be seen as a possible step.

Meanwhile, in order to determine that the vibration generated in the vibration sensing step B3 is vibration caused by an organism, it is necessary to block the possibility that the vibration is generated by other factors. The blocking step (B1) can be seen as a step of blocking the vibration generated by itself in the laundry treatment apparatus before the vibration sensing step (B3) is performed.

In other words, the blocking step (B1) can be viewed as a premise for accurately determining the presence or absence of an organism by more precisely detecting the vibration generated in the vibration sensing step (B3).

The blocking step (B1) may include a checking step (B1-1) of checking whether the laundry treatment apparatus is in operation. The operation may mean determining whether the driving unit 40, the water supply valve 70B, the drain unit 72, and the like operate.

In the preparation step B1-2, all operations of the laundry treatment apparatus are stopped or stopped. In other words, it may mean blocking the possibility of all vibrations occurring in the laundry treatment apparatus itself. This may include stopping rotation of the drum 30, stopping water supply, stopping drainage, stopping supply of steam or hot air, and the like.

When the blocking step (B1) is performed, the control unit (P) may perform a vibration sensing step (B3) of detecting vibrations generated by the motion of the living body in the tub (20).

The vibration detection step (B3) includes a first vibration detection step (B3-1) of detecting whether vibration has occurred for a first time (T1) or more in the vibration detection unit 80, and a second vibration detection step after the first vibration detection step is completed. It may include a secondary vibration detection step (B3-2) of detecting whether vibration has occurred for more than 2 hours (T2).

The second vibration detecting step B3-2 of the vibration detecting step B3 may be omitted if no vibration is detected in the first vibration detecting step B3-1. This is to prevent the washing procedure from being delayed by performing an additional step even though no vibration is detected in the first detection step (B3-1).

In the determining step (B4), if no vibration is detected in the vibration detecting step (B3) or when vibration is detected only in the first vibration detecting step (B3-1), it can be determined that there is no living organism inside the clothing receiving unit. there is.

This is because, if no vibration is detected in the vibration sensing step (B3), it may be determined that the living body does not exist in the clothing receiving unit 20'. In addition, if the vibration is detected only in the first vibration detection step B3-1, it can be determined that the vibration is not an internal factor of the laundry treatment apparatus, such as an external impact of the laundry treatment apparatus or transmission of vibrations from the external environment.

On the other hand, in the second vibration detection step (B3-2), when vibration occurs in the first vibration detection step (B3-1), it is centered on whether the vibration is Z-axis, X-axis vibration, or Z-axis and X-axis rotational vibration. can be detected as

This is because, if it is an external factor of the laundry treatment apparatus, the vibration in the above-described direction does not occur. Accordingly, in the determining step (B4), if the vibration corresponds to at least one of a height direction, a front-back direction, and a rotational vibration of the laundry treatment apparatus, it may be determined that a living organism exists in the laundry treatment apparatus.

Of course, in the determination step (B4), it can be determined based on whether the vibration in the above-described direction is detected in the first and second vibration sensing steps, and the vibration in the other direction can be detected and ignored. In this case, whether the Z-axis or X-axis vibration, or the Z-axis or X-axis rotational vibration is a vibration that cannot be generated by a factor outside the laundry treatment apparatus and the laundry treatment apparatus, it can be defined as abnormal vibration.

On the other hand, in the determination step (B4), the controller (P) may determine that a living organism exists inside the clothing accommodation unit when vibration is sensed in both the first vibration detection step and the second vibration detection step.

The first time T1 and the second time T2 may be the same. However, in the second vibration detecting step B3-2, the second time T2 may be longer than the first time T1 in order to accurately detect the vibration.

For example, the first time T1 may be 3 seconds, and the second time T2 may be 5 seconds.

Meanwhile, after the first vibration detecting step B3-1 is finished, the second vibration detecting step B3-2 may be performed after a predetermined time elapses. For example, after the first vibration detection step B3-1 is finished, 5 seconds later, the second vibration detection step B3-2 may be performed.

In addition, the second vibration detection step B3-2 may be performed unconditionally regardless of whether vibration is sensed in the first vibration detection step B3-1. This is because the possibility that the organism does not move in the first vibration detection stage (B3-1) cannot be excluded.

In the present invention, the biological detection (B) may perform an operation inducing step (B2) of temporarily operating the clothing treatment apparatus to induce the movement of the living body inside the clothing receiving unit before the vibration detection step (B3) is performed. .

Even if there is an organism inside the clothing accommodating part 20', there may be a case where the living organism does not operate at all due to reasons such as being in a sleeping state. Therefore, since the vibration including the abnormal vibration is not detected in the vibration sensing step B3, there is a possibility that the living body is determined not to be present in the determination step B4. Accordingly, in the operation inducing step (B2), if the living body is in the clothing receiving unit 20', it is forced to operate, thereby induced to generate vibration.

In the operation inducing step (B2), at least one of the driving unit 40 and the water supply valve 70B may be operated temporarily. For example, by controlling the driving unit 40 to rotate the drum 30 about 1/3 to 1/2 turn, the movement of the living body can be induced.

In addition, by opening the water supply valve (70B), it is possible to spray water temporarily to the tub (20). When the laundry treatment apparatus 100 of the present invention is provided with a spray nozzle or a steam generator, water or steam may be temporarily sprayed into the tub 20 or the drum 30 . In addition, air may be temporarily supplied to the inside of the drum 30 through a hot air supply unit (not shown). In addition, a temporary sound or music may be reproduced on the display unit 17 . As a result, in the operation inducing step (B2), any method may be performed as long as an appropriate stimulus can be applied to the living body inside the tub 20 or the drum 30.

Through the motion induction step (B2), it is possible to more clearly detect and determine the vibration of the living body in the vibration sensing step (B3), thereby greatly improving the accuracy of detecting the living body.

In the determination step (B4), if there is no vibration in the vibration sensing step (B3), a non-existence determination (B4-1) of determining that there is no living organism in the drum 30 may be performed. In addition, in the determination step (B4), if the vibration was detected in the first vibration detection step (B3-1), but there is no vibration detected in the second vibration detection step (B3-2), the first vibration detection step (B3) The vibration sensed in -1) may be first determined (B4-11') as a temporary movement of the clothes accommodated in the clothes accommodating unit 20' or a vibration caused by factors external to the clothes processing apparatus. As a result, in the determining step (B4), there is no living organism in the tub 20 or the drum 30, and finally, the non-existence determination (B4-1) may be performed.

In addition, when both vibrations are detected in the first vibration detecting step (B3-1) and the second vibration detecting step (B3-2) in the determining step (B4), the inside of the tub 20 or the drum 30 You can make an existence judgment (B4-2) that determines that living things exist in

Furthermore, when abnormal vibration occurs in the first vibration detection step (B3-2) in the determination step (B4) or abnormal vibration occurs in the second vibration detection step (B3-2), the tub 20 or An existence determination (B4-2) may be made in which it is determined that an organism exists in the drum 30 .

When the determination step (B4) is finished, the control unit P may display the determination result on the display unit 17 or the external terminal 300, and end the biological detection.

6 is a diagram illustrating a control method capable of determining whether to allow remote control or taking action when a living organism is inside the laundry treatment apparatus.

As described above, in order to remotely control the clothes processing apparatus 100 with the external terminal 300 , the external terminal 300 transmits request information requesting remote control of the clothes processing apparatus 100 to the communication. may be transmitted to the module 200 .

The external terminal 300 transmits the request information to the communication module 200, performs an authentication operation in the control unit P or the server, and checks whether the clothes processing apparatus 100 is in a state allowing remote control. can do.

That is, even if there is a remote control request through the external terminal 300, the control unit P may be provided to allow remote control only in the case of non-existence determination (B4-2) by performing biological detection. This is because it is difficult for a user at a remote location to directly check and perform remote control when a living organism is inside the laundry treatment apparatus.

Specifically, the remote system including the laundry treatment apparatus 100 and the external terminal 300 of the present invention may include a request detecting step (A) of detecting the reception of the request information in the communication module 200 .

When the request detection step (A) is performed, the control unit (P) may perform the biological detection (B). At the same time, the control unit (P) may also perform an authentication operation of the external terminal (300).

In addition, when the biological detection (B) is performed, the permit determination step (C) of determining whether to permit the remote control may be performed according to the determination result of the determination step (B4).

The permission determination step (c) may be a step of determining whether the control information is received or whether the control information is implemented.

Specifically, the action step (D) of performing a corresponding action according to the result of the allowability determination step (c) may be performed.

In the action step (D), if it is determined in the determination step (B4) that there is no living organism in the clothing receiving unit (B4-1), the door for opening and closing the opening of the cabinet is locked, or the control is performed by the external terminal. When it is determined that there is an organism in the clothing receiving unit in the permitting step (D-1) of performing at least one of waiting to receive a command or executing the control command, and the determining step (B4) ( B4-2), unlocking a door for opening and closing the opening of the cabinet, blocking receiving the control command from the external terminal, or blocking execution of the control command It may include a disallow step (D-2).

Specifically, in the disallowing step (D-2), the door is unlocked to induce escape of the living body, and the reception of the control command is fundamentally blocked to block the possibility of performing remote control itself, and the external terminal Even if the control command is received through 300, the operation of the laundry treatment apparatus is blocked by ignoring the execution or execution of the control command.

Accordingly, when there is a living organism inside the laundry treatment apparatus 100, it is possible to prevent a safety accident by blocking the remote control of the laundry treatment apparatus 100 with an external terminal.

Conversely, it is possible to allow the clothes treatment apparatus 100 to be remotely controlled by the external terminal 300 only when there is no living organism inside the laundry treatment apparatus 100 .

The action step (D) may include transmitting the content determined in the permission determination step to the external terminal. That is, the contents of the disallowing step (D-2) may be transmitted to the external terminal, or the contents of the allowing step (D-1) may be transmitted to the external terminal.

Accordingly, the remote user can accurately recognize not only the state of the clothes treatment apparatus 100 but also the presence or absence of living organisms and actions taken through the external terminal 300 .

On the other hand, even if the remote control request step (A) is not performed, if the above-described biological detection (B) is performed with an input such as the input unit 17 and is completed, the control unit P determines in the determination step (B4) The above action step (D) of taking action according to the result may be performed.

In the action step (D), if the existence determination (B4-2) is determined in the determination step (B4), the presence of the living organism is displayed on the display unit 17 or the input unit 16 is prevented from being input At least one of inactivating or unlocking the door may be performed as much as possible. This not only induces the escape of the living organism and safety measures for the user, but also causes the user to close the clothes processing apparatus without recognizing it. to prevent it from working.

That is, the action step (D) can always be performed when the biological detection (B) is performed, regardless of whether or not there is a remote control request.

In the method of controlling the laundry treatment apparatus of the present invention, a plurality of the laundry treatment apparatuses 100 are provided, and the external terminal 300 communicates with the communication modules 200 of the plurality of laundry treatment apparatuses to control the laundry treatment apparatus. It can be applied as it is in commercial laundry, each remotely controlled.

That is, when there is an operator controlling the laundry treatment apparatus with an external terminal at a place separated from each laundry treatment apparatus in a commercial laundry, the above-described control method or biological detection (B) may be performed.

For example, the remote control command may be a tub washing command for rotating the drum 30 to wash the inside of the tub 20 .

When the tub washing command is transmitted to the specific laundry treatment apparatus 100 through the external terminal 300, the laundry treatment apparatus 100 performs the biological detection (B) and receives the result of the determination step (B4). Accordingly, it is possible to determine whether or not to implement the tub washing command. In other words, the tub washing command may be performed only when there is no living thing inside the specific laundry treatment apparatus 100 .

The present invention may be modified and implemented in various forms, but the scope of the rights is not limited to the above-described embodiments. Therefore, if the modified embodiment includes the elements of the claims of the present invention, it should be regarded as belonging to the scope of the present invention.
