1 is a view showing the configuration of an air purifier according to an embodiment of the present invention.

Referring to FIG. 1, the air purifier 100 includes an inlet 105, a sensor unit 110, an air purifier 120, a first outlet 130, a second outlet 132, and a first camera 140. , A second camera 142, a speaker 150, a microphone 160, a memory 170, and a controller 180.

Air in the space is introduced through the inlet 105.

The sensor unit 110 senses fine dust contained in the air introduced through the inlet 105.

The air purification unit 120 purifies the air when the sensed concentration of the fine dust is greater than or equal to a threshold value.

The first outlet 130 discharges the purified air into the first space (living room 200).

The second outlet 132 discharges the second purified air to a second space (main room) different from the first space (living room).

The first camera 140 photographs a first user in the first space. For example, the first space may be a living room.

The second camera 142 photographs a second user different from the first user in the second space (main room). For example, the second space may be a master bedroom.

The speaker 150 outputs sound to the first space. The speaker 150 includes a first speaker 152 and a second speaker 154. The second speaker 154 has a property different from that of the first speaker and includes a second speaker 154 that outputs sound to a second space.

For example, the first speaker 152 may be a 5.1ch omnidirectional speaker, and the second speaker 154 may be a directional speaker. The topographic speaker is a speaker system with directivity that radiates sound only in a target direction, and means that two or more speakers of the same diameter are arranged on the same plane to operate as a single speaker as a whole. It is also called a column speaker because its height is larger than the width or depth, and it is shaped like a column, and is widely used in gymnasiums, auditoriums, and outdoor stadiums. It does not occupy the floor area and has the advantage of being able to adjust the listening position to the height of the ear.

The microphone 160 processes an external sound signal into electrical voice data. The processed voice data may be utilized in various ways according to a function (or an application program being executed) being executed by the mobile terminal 100. Meanwhile, the microphone 160 may be implemented with various noise removal algorithms for removing noise generated in a process of receiving an external sound signal.

The memory 170 stores a preset motion image of the user.

The controller 180 determines whether to switch to the directional speaker based on the images of the first camera 140 and the second camera 142, and controls at least one of the first outlet 130 and the second outlet 132 do.

Specifically, when the first camera 140 photographs the first user, the controller 180 determines that the second camera 142 photographs the second user based on the photographed image of the first user, and determines When the second camera photographs the second user according to the result, it determines whether to switch the speaker based on the captured image of the second user, switches the speaker according to the determination result, and At least one of the first outlet and the second outlet is controlled based on the image and the captured image of the second user.

The first camera 140 and the second camera 142 include a TOF camera.

TOF camera refers to a camera with a TOF sensor attached to a general camera. Specifically, an image sensor that shoots and displays a scene derives a 2D-based result. If the TOF sensor intervenes here, depth measurement becomes possible and 3D results can be realized. TOF (Time of Flight) refers to the time when sound waves or light sources are transmitted to the subject and returned through the subject. The TOF sensor is a kind of component that can detect this role.

The depth map refers to an image containing information related to the distance from an observation point to an object surface in 3D computer graphics.

The TOF camera captures a first image including a depth map. When shooting with a TOF camera, an image is obtained as a result of applying the original image, the depth map, and the depth map to the original image.

2 is a flowchart illustrating a method of controlling an air purifier according to an embodiment of the present invention. The present invention is implemented by the controller 180.

Referring to FIG. 2, first, fine dust contained in air introduced through the inlet 105 is sensed through the sensor unit 110 (S210).

When the concentration of the sensed fine dust is greater than or equal to the threshold value, air is purified through the air purification unit 120 (S220).

When the first camera 140 photographs the first user in the first space (S230), the second camera 142 photographs the second user in the second space based on the captured image of the first user. It is determined (S240).

When the second camera 142 photographs the second user according to the determination result (S250), it is determined whether to switch the speaker based on the photographed image of the second user (S260).

The speaker 150 is switched according to the determination result (S270).

At least one of the first outlet and the second outlet is controlled based on the captured image of the first user and the captured image of the second user (S280).

3 is a flowchart illustrating a method of controlling an air purifier according to an embodiment of the present invention. 3 is performed by the controller 180.

First, the fine dust contained in the air introduced through the inlet 105 is sensed through the sensor unit 110, and when the concentration of the sensed fine dust is greater than or equal to the threshold value, the air is purified through the air purifier (S310). .

The first camera 140 in the first space is activated (S312).

When the first camera 140 photographs the first user in the first space (S314), object motion recognition is performed based on the captured image of the first user to check the state of the first user (S316). Here, the first space may be a living room.

If the first camera 140 fails to photograph the first user in the first space (S314), the first camera 140 is controlled to photograph the first user again.

It is checked whether the state of the first user is a preset first state (S318). Here, the first state means a state in which the first user sits on the sofa and watches TV.

When the first state is satisfied (S318), the second camera 142 in the second space is activated (S320). When the state of the first user is determined as the preset first state, the second camera 142 is activated to control the second camera 142 to photograph the second user. Here, the first state means a state in which the first user sits on the sofa in the living room and watches TV.

When the second camera 142 photographs the second user in the second space (S322), object motion recognition is performed based on the captured second user's image to check the state of the second user (S324). Here, the second space may be a master room.

If the second camera 140 fails to photograph the second user in the bedroom (S326), the second camera 140 is controlled to photograph the second user again.

It is checked whether the state of the second user is a preset second state (S326). Here, the second state means a state in which the second user lies in bed and sleeps in the second space. In addition, since the second state is based on the first state, satisfying the second state is that i) the first user in the first space is sitting on the sofa and watching TV, and ii) the second user in the second space Means lying in bed and sleeping.

If the recognized object operation is not in the second state (S326), the first outlet is closed and the second outlet is opened (S328).

For example, when a first user watches TV in a living room and a second user does not sleep in the master room (S326), when the first user watches TV through a 5.1 channel speaker, both the living room outlet and the bedroom outlet are When opened, a second user who does not sleep may be disturbed by the sound of the TV. In this case, it is possible to improve user convenience by opening the home outlet and closing the living room outlet to allow the first user to comfortably watch TV, and supplying purified air only to the home, which is a relatively closed and small space.

When the recognized object operation is determined as the second state (S326), it is determined whether to switch the speaker (S330). Specifically, whether to switch the speaker is determined based on the image of the first user and the image of the second user.

For example, if a first user in a living room is sitting on a sofa and watching TV, and a second user in a bedroom is sleeping in a bed, it is determined to switch speakers.

When it is determined to switch the speaker (S330), the first speaker is deactivated (S332).

Next, the second speaker is activated (S334).

The speaker 150 includes a first speaker 152 that outputs sound to the first space, and a second speaker 154 that has different properties from the first speaker and outputs sound to the second space.

For example, the first speaker 152 may be a 5.1ch omnidirectional speaker, and the second speaker 154 may be a directional speaker. Accordingly, since the first speaker 152 is switched to the second speaker 154, sound is transmitted only to the first user in the first space, and sound is not well transmitted to the second user in the second space.

Here, the first speaker and the second speaker are connected to the TV in the living room, and when the TV is activated, the first speaker is activated. When the speaker switching is determined, the first speaker is in an inactive state, and the second speaker is in an active state. Further, when the speaker switching is re-determined, the second speaker is in an inactive state, and the first speaker is in an active state.

The first discharge port for discharging the purified air to the first space is opened, and the second discharge port for discharging the purified air to the second space is opened (S336).

When the first user watches TV in the living room and the second user sleeps in the bedroom (S326), when the first user watches TV through a 5.1-channel speaker, if both the living room outlet and the bedroom outlet are open, sleep The sleeping second user may be disturbed by the TV sound.

In this case, the speaker is changed from a 5.1-channel speaker to a directional speaker, and although the first user is somewhat inconvenient, the second user is not disturbed by the TV noise even when watching TV with the directional speaker and opening both the living room and the main room outlet, Since it is possible to supply purified air to the living room and the master room at the same time, user convenience can be improved.

If it is not determined to switch the speaker, the activation of the first speaker is maintained (S338).

For example, if it is determined that there is no second user in the bedroom, activation of the first speaker is maintained.

The first outlet is opened and the second outlet is closed (S340).

For example, when a first user watches TV in the living room and there is no second user in the bedroom (S330), when the first user watches TV through a 5.1-channel speaker, when both the living room outlet and the bedroom outlet are opened, Purified air may be unnecessarily supplied even when there is no second user in the bedroom. In this case, while maintaining the speaker as a 5.1-channel speaker, the first user can watch TV with the 5.1-channel speaker, open the living room outlet, and close the main room outlet to supply purified air only to the living room, thereby saving energy. Therefore, user convenience can be improved.

According to the present invention, when the first user is sitting on the sofa and watching TV in the living room and the second user is sleeping on the bed in the bedroom, the speaker is switched to the directional speaker, and both the first and second outlets are opened. do.

Therefore, when the air purifier is operated in both the living room and the master room, TV noise can be transmitted between the first and second outlets. By switching the speaker from an omni-directional speaker to a directional speaker, the TV noise is transmitted to the sleeping user. As it can be prevented, user convenience can be improved.
