The frame 200 may be detachably mounted inside the air conditioner 10 . Specifically, the outer periphery of the frame 200 may be supported in such a way that it fits into the inner periphery of the air conditioner 10 , but the present invention is not limited thereto.

The filter module 100 may include a supply housing 110 , a recovery housing 120 , and a filter 130 . The supply housing 110 and the recovery housing 120 may be detachably mounted to the frame 200 .

The supply housing 110 and the recovery housing 120 may be disposed to be spaced apart from each other. Although the supply housing 110 and the recovery housing 120 are shown to be vertically spaced apart, this is an example, and it is also possible to be spaced apart from one another to the left and right.

A portion of the filter 130 is exposed between the supply housing 110 and the recovery housing 120 to filter air introduced from the outside. The filter 130 may be a pre-filter, but is not limited thereto, and various functional filters such as a HEPA filter, a deodorizing filter, and an antibacterial filter may be replaced by the filter module 100 .

Although only one filter module 100 is shown in the drawing, the present invention is not limited thereto, and a plurality of filter modules 100 may be continuously disposed along the air flow direction.

Specific operations and configurations of the supply housing 110 , the recovery housing 120 , and the frame 200 will be described later in detail with reference to FIGS. 3 to 5 .

3 is an exploded perspective view illustrating the configuration of the filter module 100 and the frame 200 in FIG. 2 . 4 is an exploded perspective view showing the recovery housing 120 and the frame 200 in FIG. 3 in an enlarged manner. 5 is an exploded perspective view showing the supply housing 110 in FIG. 3 in an enlarged manner.

Referring to FIG. 3 , the frame 200 may include a first accommodating space 210 and a second accommodating space 220 corresponding to the shapes of the supply housing 110 and the recovery housing 120 . As the supply housing 110 and the recovery housing 120 are mounted in the first accommodating space 210 and the second accommodating space 220 , respectively, the filter module 100 can be stably supported by the frame 200 . have.

The supply housing 110 and the recovery housing 120 may each have a supply roller 111 and a recovery roller 121 mounted therein. The supply roller 111 and the recovery roller 121 are shown as cylindrical, but the shape is not limited thereto.

The supply roller 111 may have one end of the filter 130 wound in the form of a roll. That is, the filter 130 may have a shape in which one end is rolled around the supply roller 111 by being elongated in the horizontal direction of the supply roller 111 .

The recovery roller 121 may be connected to the other end of the filter 130 . The supply roller 111 and the recovery roller 121 may be rotatably supported by

respective shafts

112 and 122 .

Referring to FIG. 4 , the driving device 300 may include a motor 310 for generating a rotational force and a plurality of

gears

320 and 330 for transmitting the rotational force to the recovery roller 121 . Specifically, when the motor 310 is driven, the shaft gear 330 engaged with the motor gear 320 may rotate. Accordingly, the shaft 122 of the recovery roller 121 may rotate so that the filter 130 is wound around the recovery roller 121 .

The motor 310 and the motor gear 320 for transmitting the rotational force of the motor 310 to the recovery roller 121 may be mounted on the frame 200 . Accordingly, even when it is necessary to replace the filter module 100 , the motor 310 and the motor gear 320 are not replaced together with the filter module 100 , but are mounted on the frame 200 for each lifetime. can be used

Meanwhile, although not shown, the motor 310 may be directly connected to the shaft 122 of the recovery roller 121 to rotate the recovery roller 121 . Accordingly, since it is not necessary to provide the plurality of

gears

320 and 330 as the rotational force transmission device, the rotational force lost by the plurality of

gears

320 and 330 can be minimized, and the number of parts used is minimized to achieve a slim fit. An air conditioner 10 may be provided.

When the filter 130 replacement time arrives or a user command for filter 130 replacement is input, the air conditioner 10 rotates the recovery roller 121 to control the driving device to replace the filter 130 . It may include a processor (not shown).

Specifically, the processor may control the driving device 300 to replace the filter 130 by rotating the recovery roller 121 by the spaced distance between the supply housing 110 and the recovery housing 120 according to a preset condition. can

As the filtering operation area of the filter 130 is changed, a new filter 130 can be used periodically, so that the performance of the air conditioner 10 can be maintained in an excellent state, and the filter 130 can be directly replaced and It can reduce the hassle of users who have to clean.

Referring to FIG. 5 , the air conditioner 10 may include a gear 113 and a damper 140 connected to the shaft 112 of the supply roller 111 . The damper 140 may act in a direction opposite to the rotation of the supply roller 111 so that the filter 130 maintains tension in the direction of the supply roller 111 .

Specifically, the type of the damper 140 may be a rotary damper, and the gear 113 connected to the shaft 112 of the supply roller 111 and the gear 141 of the damper 140 mesh with each other. can Accordingly, it is possible to prevent the filter 130 from being unwound due to the unintentional rotation of the supply roller 111 .

That is, since the filter 130 maintains the tension by the damper 140 , it is possible to filter air while having a constant shape without lifting any part. Accordingly, it is possible to prevent a problem that air that has not passed through the filter 130 flows into the air conditioner 10 , and the overall efficiency of the air conditioner 10 can be increased.

The torque value of the damper 140 may be smaller than the driving torque value of the motor 310 . Accordingly, even if the damper 140 brakes the rotation of the supply roller 111 , the filter 130 may be smoothly replaced by the motor 310 having a relatively large torque value.

6 is a front view of the filter 130 according to an embodiment of the present disclosure as viewed from the front. FIG. 7 is a cross-sectional view taken along line I-I in FIG. 6 . FIG. 8 is an enlarged cross-sectional view of the metal member 131 in FIG. 6 .

6 to 8 , the filter 130 may include a metal member 131 at an edge thereof. It is sufficient if the material of the metal member 131 responds to magnetic force, such as iron, copper, aluminum, etc., and is not necessarily limited to the metals listed above.

As shown in FIG. 8 , the metal member 131 may be coupled to the filter 130 in such a way that it is inserted into a gap formed at the edge of the filter 130 . However, the present invention is not limited thereto, and the metal member 131 may be adhered to the edge of the filter 130 , or the mesh itself of the filter 130 may be formed of a metallic material.

In the frame 200 , the magnetic member 230 may be disposed at a position corresponding to the metal member 131 . That is, since the metal member 131 of the filter 130 and the magnetic member 230 of the frame 200 come into contact with each other by magnetic force, the edge of the filter 130 may firmly contact the frame 200 . .

However, the arrangement of the metal member 131 and the magnetic member 230 is not limited thereto, and the magnetic member 230 is disposed at the edge of the filter 130 by changing positions, and the metal member ( 131) may be disposed. The magnetic force between the metal member 131 and the magnetic member 230 may be determined at a level that does not prevent movement of the filter 130 by the motor 310 .

Accordingly, a gap between the edge of the filter 130 and the frame 200 may not be widened. Since the filter 130 can be disposed at an accurate position on the air flow path without a lifting phenomenon, unfiltered air leaks through a gap between the filter 130 and the frame 200 and flows into the air conditioner 10 . can prevent

9 to 10 , a thin plate 132 having a plurality of grooves 133 formed at an edge of the filter 130 may be disposed. Like the metal member 131 , the thin plate 132 may be inserted into a gap formed at the edge of the filter 130 and may be adhered to the edge of the filter 130 , but is not limited thereto.

The plurality of grooves 133 formed in the thin plate 132 may be formed at regular intervals from each other. The thin plate 132 may be formed of a material such as plastic or iron and may have a thin plate shape, but is not limited thereto.

The frame 200 may include a caterpillar 400 at a position corresponding to the thin plate. The caterpillar 400 may have a chain shape having a closed path, and may include a plurality of teeth 410 protruding outward.

The teeth 410 of the caterpillar 400 and the groove 133 of the thin plate 132 may be engaged with each other at at least one place. When the filter 130 is replaced, the caterpillar 400 engaged with the thin plate 132 may rotate along the movement direction of the filter 130 without using a separate power.

When the filter 130 is replaced, the filter 130 coupled to the caterpillar 400 does not deviate from its position and can move toward the recovery housing 120 while maintaining a straight shape, so the filter 130 is stably can be replaced.

In addition, since the edge of the filter 130 is coupled to the caterpillar 400 on the frame 200 side, the filter 130 may not deviate from its position due to an external force such as air flow pressure. Accordingly, it is possible to prevent the problem of air leaking through the gap that may be formed between the edge of the filter 130 and the frame 200 .

In the above, preferred embodiments of the present disclosure have been illustrated and described, but the present disclosure is not limited to the specific exemplary embodiments described above, and it is common in the technical field to which the disclosure pertains without departing from the gist of the present disclosure as claimed in the claims. Various modifications are possible by those having the knowledge of, of course, and these modifications should not be individually understood from the technical spirit or prospect of the present disclosure.
