1 is a perspective view of an air purifier 100 according to an embodiment of the present invention, FIG. 2 is an exploded view of the air purifier 100 according to an embodiment of the present invention, and FIG. 3 is an air purifier according to an embodiment of the present invention. It is a cross section of (100).

1 to 3, the air purifier 100 includes a base 110, a body 120, a fan 130, a filter 140, a contamination sensor 150, motion sensors 161, 162, and 163, a pop-up It includes a module 170, a louver 180 and a control unit (not shown).

The base 110 forms the entire lower part of the air purifier 100, and the main body 120 is rotatably installed on the base 110. In the drawing, it is illustrated that the base 110 is installed on the floor, and the main body 120 is rotatably installed around a rotation axis perpendicular to the base 110. However, if necessary, the base 110 may be installed on a side wall or ceiling, and the main body 120 may be rotatably installed around a rotational axis horizontal to the base 110 . When the base 110 is installed on a side wall or ceiling, the base 110 will form the entire side or top of the air purifier 100. Hereinafter, for convenience of understanding, a case in which the base 110 is installed on the floor as shown in the drawings and the main body 120 is rotatably installed around a rotation axis perpendicular to the base 110 will be described.

The main body 120 is rotatably installed on the base 110 as mentioned above. In the drawings, the main body 120 is illustrated as being formed in the form of a quadrangular column, but the main body 120 may be formed in other shapes such as a triangular column or a cylindrical column as needed.

The main body 120 is formed with a suction port 120a for inhaling air from the outside to the inside and an opening 120b through which the air can pass. At this time, the inlet (120a) is formed on the side of the main body 120, may be particularly formed on the front of the main body (120). Also, the opening 120b may be formed on the upper surface of the main body 120 . Here, the side surface refers to the pillar surface of the main body 120 . In addition, the front side refers to the front side of the main body 120 based on the normal use state of the air purifier 100, and the upper side refers to the upper side of the main body 120, which distinguishes the relative position from the main body 120 It is for reference only and does not imply an absolute location.

The fan 130 may be disposed inside the body 120, and serves to form an air flow from the intake port 120a of the body 120 to the opening 120b.

The filter 140 is disposed between the inlet 120a and the opening 120b of the main body 120 to purify air. Since the specific structure and components of the filter 140 are well known, a detailed description thereof will be omitted.

The contamination level sensor 150 serves to measure the degree of contamination of ambient air such as dust and odor. Since the specific method of the pollution level sensor 150 is also known, a detailed description thereof will be omitted.

The first motion sensor 161 , the second motion sensor 162 , and the third motion sensor 163 are coupled to the main body 120 to sense motion. To this end, the first motion sensor 161, the second motion sensor 162, and the third motion sensor 163 are composed of infrared sensors and can detect the movement by measuring the body temperature of a person or animal. Of course, as long as it can detect motion, it can be configured in other ways, such as a camera sensor or an ultrasonic sensor. On the other hand, here, the first, second, and third are simply to distinguish and refer to each motion sensor, and do not mean a mutual precedence relationship or a top-down relationship.

More specifically, the first motion sensor 161 is coupled to the front surface of the main body 120, and senses movement by directing the inlet 120a of the main body 120 toward the opened direction.

In addition, the second motion sensor 162 senses motion toward the right side of the first motion sensor 161 . For example, it may be coupled to the right side of the body 120. Here, the right side refers to a direction rotated at a predetermined angle in a clockwise direction around the rotation axis when the air purifier 100 is in a normal use state, which is a relative position or direction in the main body 120 It is intended to refer, but does not imply an absolute location or direction.

In addition, the third motion sensor 163 senses motion toward the left side of the first motion sensor 161 . For example, it may be coupled to the left side of the main body 120. Here, the left side is a concept opposite to the right side, and refers to a direction rotated at a predetermined angle in a counterclockwise direction around the rotation axis when the air purifier 100 is used as a standard. This is also for distinguishing and referring to the relative position or direction in the main body 120, not the absolute position or direction.

The pop-up module 170 penetrates the opening 120b of the main body 120 and is installed to be slidable upward and downward.

In addition, the pop-up module 170 is formed with a first outlet 170a and a second outlet 170b communicating with the opening 120b of the main body 120 to discharge air from the inside to the outside, respectively. In the drawing, it is illustrated that the first outlet 170a is formed on the front surface of the pop-up module 170, and the second outlet 170b is formed on the upper surface of the pop-up module 170.

In this case, the pop-up module 170 moves downward and is introduced into the opening 120b of the main body 120, as shown in FIG. 5A, so that the first outlet 170a is closed by the main body 120, and As shown in FIG. 5C , by moving upward and being withdrawn from the opening 120b of the main body 120, the first outlet 170a may be moved between the second positions in which the opening is opened.

For reference, FIG. 5B shows an intermediate position between the first position and the second position. Hereinafter, this is referred to as a third position of the pop-up module 170.

The louver 180 is rotatably installed on the pop-up module 170, and as shown in FIG. 5A, the opening 120b of the main body 120 leads to the first outlet 170a of the pop-up module 170. As shown in the fourth position of closing the first flow path F1 and FIG. 5C, the second flow path F2 leading from the opening 120b of the main body 120 to the second outlet 170b of the pop-up module 170 It is rotatable between the fifth position of closing.

For reference, FIG. 5B shows an intermediate position between the fourth position and the fifth position. Hereinafter, this is referred to as a sixth position of the louver 180.

In particular, the louver 180 rotates in conjunction with the movement of the pop-up module 170, rotates to the fourth position when the pop-up module 170 is in the first position, and rotates to the fourth position when the pop-up module 170 is in the second position. It can rotate to the fifth position.

A controller (not shown) controls the main body 120, the fan 130, and the pop-up module 170 based on signals from the contamination level sensor 150 and the motion sensors 161, 162, and 163. Describe the control method.

First, when the motion sensors 161, 162, and 163 detect a movement of a predetermined level or higher in a certain direction, the controller rotates the main body 120 so that the inlet 120a of the main body 120 faces that direction. For example, when the second motion sensor 162 detects motion, the controller rotates the main body 120 to the right as shown in FIG. 4B from the state of FIG. 4A. On the other hand, when the third motion sensor 163 detects motion, the controller rotates the main body 120 to the left as shown in FIG. 4C.

If the motion sensor detects motion in a specific direction, it may mean that there is a possibility that the air pollution level is significantly increased due to the motion in that direction. Therefore, the control unit rotates the main body 120 to more directly intake and purify the air from that direction, thereby purifying the air more efficiently.

On the other hand, if the value by the contamination level sensor 150 is lower than a predetermined range, the controller operates the fan 130 at a relatively low output.

Also, the control unit allows the pop-up module 170 to be in the first position. In other words, as the pop-up module 170 is introduced into the opening 120b of the main body 120, the first outlet 170a is closed by the main body 120.

At this time, the louver 180 may close the first flow path F1 at the fourth position.

According to this, the air is purified by the filter 140 and is discharged upward only through the second outlet 170b without being discharged through the first outlet 170a as shown in FIG. 5A. Accordingly, noise that may occur while air is discharged through the first outlet 170a may be reduced.

If the value by the contamination level sensor 150 is within a predetermined range, the controller operates the fan 130 with a higher output.

In addition, the control unit slightly moves the pop-up module 170 upward so as to be in the third position. In other words, the pop-up module 170 is slightly withdrawn from the opening 120b of the main body 120 so that the first outlet 170a is partially opened.

At this time, the louver 156 may simultaneously partially open the first flow path F1 and the second flow path F2 at the sixth position.

According to this, the air is purified by the filter 140, and as shown in FIG. 5B, some is discharged through the first outlet 170a to the front (the direction in which the inlet 120a of the main body 120 is opened), and the rest Some may be discharged upward through the second outlet 170b. Therefore, since a large amount of air can be discharged through a larger area than in the case of FIG. 5A, the purification effect can be increased.

If the value by the contamination level sensor 150 is higher than a predetermined range, the controller operates the fan 130 at the highest output.

In addition, the control unit further moves the pop-up module 170 upward so as to be in the second position. In other words, the pop-up module 170 is further withdrawn from the opening 120b of the main body 120 so that the first outlet 170a is completely opened.

At this time, the louver 180 may close the second flow path F2 at the fifth position.

According to this, the air can be purified by the filter 140 and discharged forward through the second outlet 170b as shown in FIG. 5C. Therefore, air is sucked in and purified from the direction in which the movement occurs, and then air is discharged in the same direction, so that the air can be purified more quickly and intensively.

Afterwards, when the value by the contamination sensor 150 goes down, the control unit again operates the fan 130 at a low output, and moves the pop-up module 170 downward so that it is in the third position or the first position.

At this time, the louver 180 will also rotate to the sixth or fourth position correspondingly thereto.

The air purifier according to the embodiment of the present invention described above and shown in the drawings is only one embodiment. The technical idea of the present invention is not limited to the above embodiment. For example, in the above, the first outlet 170a of the pop-up module 170 has been described as being formed only on the front side of the pop-up module 170. You will be able to. As described in the claims, those skilled in the art in the technical field to which the present invention belongs will have the technical spirit to the extent that it can be modified in various ways.
