The door 11 is provided with a gasket 12 (or a damper) along a portion contacting the case 10. The gasket 12 cuts off the air flow through the gap between the door 11 and the case 10. [ In addition, the door 11 is provided with a display unit 13 which displays operation information.

The interior of the case 10 is partitioned into a plurality of spaces by barrier ribs 14, The first partition 14 is installed in the lateral direction of the case 10 to divide the inner space of the case 10 in the vertical direction. A machine room 16 is formed below the first bank 14. The machine room 16 may be provided with an air pump 21, a dust container 41, a water container 51, a fragrance container 61, and the like. The second partition 15 is installed in the vertical direction of the case 10 to divide the inner space of the case 10 in the lateral direction. A clothes receiving chamber 17 is formed on the right side of the case 10, and a duct chamber 18 is formed on the left side. The clothes accommodating chamber 17 accommodates clothes, and the duct chamber 18 is provided with a jet duct 22 through which air moves. In addition, the clothes storage room 17 is provided with a cradle 17a for storing clothes.

On the other hand, an ejection port 14a for communicating the machine room 16 and the duct chamber 18 is formed in the first partition 14, and an exhaust port 14b for communicating the clothes chamber 17 and the machine room 16 is formed do. The injection duct 22 is connected to the injection port 14a of the first partition 14 and the dust container 41 is connected to the exhaust port 14b of the first partition 14. [

The air supply unit 20 may include an air pump 21, a spray duct 22, a plurality of discharge nozzles 23-27, and a plurality of open / close valves 33-37.

The air pump 21 is installed in the machine room 16. The air discharge portion 21a of the air pump 21 is connected to the injection duct 22 through the injection port 14a of the first partition 14. The air suction portion 21b of the air pump 21 is connected to the dust container 41. [

The injection duct (22) is installed in the duct chamber (18). The injection duct 22 branches into a plurality of discharge nozzles 23-27 corresponding to the plurality of discharge nozzles 23-27. A plurality of discharge nozzles 23-27 are connected to the end of the branching jet duct 22.

A plurality of discharge nozzles (23-27) are installed in the second partition (15) so that at least one portion thereof is exposed in the clothes receiving chamber (17). The plurality of discharge nozzles 23-27 are disposed so as to be inclined downward in the direction toward the door 11. [ A plurality of ejection nozzles (23-27)

The air is sprayed with a downward slope. A plurality of ejection holes may be formed in each of the plurality of ejection nozzles 23-27.

The plurality of opening / closing valves 33-37 opens / closes the airflow ejected from the plurality of ejection nozzles 23-27. The control unit 100 controls the plurality of on-off valves 33-37 to sequentially operate the plurality of discharge nozzles 23-27. That is, air is sequentially jetted from the plurality of discharge nozzles 23-27. For example, air is sprayed first from the first discharge nozzle 23 disposed at the uppermost position of the first partition 14, air is sprayed next from the second discharge nozzle 24 disposed below the first discharge nozzle 23, The air is sequentially injected from the third ejection nozzle 25 and the fourth ejection nozzle 26 disposed thereunder and the air is finally ejected from the fifth ejection nozzle 27 disposed at the lowermost position.

The dust removing unit 40 may include a dust container 41, an exhaust port 14b, a first filter 42, and a second filter 43. The dust separation unit 40 separates foreign matter such as dust or the like that has fallen from the clothes from the air and stores them separately.

2 filter 43 is installed. The fine dust passes through the first filter 42 and flows into the dust container 41. Since the fine dust can not pass through the second filter 43, the fine dust is separated and stored in the dust container 41. [

In another embodiment, the dust container 41 may not be connected to the air suction portion 21b of the air pump 21 but may be connected to a separate exhaust pump (not shown). At this time, the air pump 21 is used to inject air into the clothes accommodating chamber 17, and the exhaust pump is used to exhaust air from the clothes accommodating chamber 17.

The exhaust port 14b is formed in the first partition 14. The air outlet 14b allows the clothes container 17 to communicate with the dust container 41. [ The air containing the dust in the clothes storage chamber 17 flows into the dust container 41 through the air outlet 14b. A foreign matter detection sensor 70 capable of detecting the inflow of dust is installed in the exhaust port 14b. The foreign substance detection sensor 70 may be constituted by an optical sensor or an ultrasonic sensor. The controller 100 controls the air injection pressure or the number of air injections based on the dust detection amount of the foreign matter detection sensor 70

I can speak. For example, when the dust measurement value of the foreign matter detection sensor 70 is greater than the reference value, the controller 100 determines that there is a large amount of dust on the clothes, and increases the air injection pressure or the number of air injection to the clothes receiving chamber. On the contrary, when the dust measurement value of the foreign matter detection sensor 70 is smaller than the reference value, the controller 100 determines that the dust on the clothes is small and reduces the air injection pressure or the number of air injection.

The steam supply unit 50 may include a water tank 51 and a heater 52, a steam duct 53, and a steam injection nozzle 54.

The water bottle 51 is installed in the machine room 16. A heater 52 is installed inside the water bottle 51 and the heater 52 warms the water stored in the water bottle 51 and evaporates it with water vapor. The steam moves through the steam duct 53 to the steam injection nozzle 54. The steam injection nozzle 54 injects steam into the clothes receiving chamber 17.

The perfume supply unit 60 may include a perfume box 61, a perfume duct 62, and a perfume spray nozzle 63.

The fragrance container (61) is installed in the machine room (16) together with the water container (51). The fragrance agent stored in the fragrance container (61) is transferred to the fragrance spraying / dispensing nozzle (63) through the fragrance duct (62). The perfume spraying nozzle (63) injects the perfume into the clothes storage room (17). The fragrance can remove the unpleasant smell of the clothes receiving chamber 17 and provide a fragrance.

In addition, the clothes care apparatus may be configured to include a dehumidifying unit or the like. The dehumidifying unit can be constituted by a heat pump or the like, and can function to remove moisture inside the clothes accommodating chamber.

3 is a view showing an initial operation of the clothes care apparatus according to one embodiment. FIG. 4 is a view illustrating a middle operation of the clothes care apparatus according to an embodiment of the present invention, and FIG. 5 is a diagram illustrating a final operation of the clothes care apparatus according to an embodiment.

As shown in Figs. 1 to 5, the user opens the door 11 and mounts the clothes in the clothes receiving chamber 17 of the case 10. Fig. The door 11 is closed and the start button of the display unit 13 is pressed to operate the clothes care apparatus.

The control unit 100 sequentially opens a plurality of on-off valves 33-37 to blow air into the clothes accommodating chamber 17 to remove dust and other foreign matter from the clothes.

More specifically, the control unit 100 first opens the first on-off valve 33 located at the uppermost position of the second partition 15 to allow air to be ejected from the first ejection nozzle 23. At this time, the other on-off valves 34-37 are all closed. Since the first discharge nozzle 23 is inclined downward, the air injected from the first discharge nozzle 23 is also sprayed downward. Therefore, the foreign matter released from the clothes by the air ejected from the first ejection nozzle 23 moves downward.

Thereafter, the second on-off valve 34 is opened to inject air from the second discharge nozzle 24. At this time, the other on-off valves 33, 35, 36, 37 are all closed. Since the second discharge nozzle 24 also has a downward slope, the air discharged from the second discharge nozzle 24

Is also sprayed downward. Therefore, the foreign matter released from the clothes by the air ejected from the second ejection nozzle 24 moves downward. The air ejected from the second ejection nozzle 24 also moves the foreign matter moving downward by the first ejection nozzle 23 in the downward direction.

In this manner, the third on-off valve 35 and the fourth on-off valve 36 are sequentially opened to allow air to be sprayed from the third discharge nozzle 25 and the fourth discharge nozzle 26. The third discharge nozzle 25 and the fourth discharge nozzle 26 gradually lower the foreign matter to the lower side of the clothes receiving chamber 17.

Thereafter, the fifth opening / closing valve 37 is opened to inject air from the fifth discharge nozzle 27. At this time, the other on-off valves 33-36 are all closed. Since the fifth discharge nozzle 27 also has a downward slope, the air injected from the fifth discharge nozzle 27 is also sprayed downward. Therefore, the foreign matter released from the clothes by the air ejected from the fifth ejection nozzle 27 moves downward, and the foreign matter moving downward by the other ejection nozzles 23-26 also moves downward. Eventually, the foreign matter passes through the exhaust port 14b and is stored in the dust container 41. [

On the other hand, the foreign matter detection sensor 70 measures the amount of dust passing through the exhaust port 14b. The foreign matter detection sensor 70 provides the dust measurement value to the control unit 100. The control unit 100 compares the dust measurement value with the reference value and determines the air injection pressure or the air sprayed from the plurality of spray ejection nozzles 23-27 Adjust the number of injections. That is, when the dust measurement value is larger than the reference value, the controller 100 may increase the air injection pressure or increase the air injection number. Conversely, when the dust measurement value is smaller than the reference value, the air injection pressure can be lowered or the number of air injections can be reduced.

Thereafter, the steam supply unit 50 is used to supply steam to the clothes storage chamber 17. Steam acts as a steam dryer and sterilizes.

Further, a fragrance such as a fiber deodorant is sprayed to the clothes receiving chamber 17 through the fragrance supply portion 60. [ The fragrance removes the unpleasant odor and emits a good fragrance.

The moisture in the clothes receiving chamber 17 is removed through a dehumidifying unit (not shown). Since the moisture contained in the clothes is eliminated, it can bring a stiff effect to clothes.

In this embodiment, for convenience of description, one discharge nozzle is provided from the top to the bottom of the first partition 14. However, in another embodiment, Two or more discharge nozzles may be provided, and such two or more discharge nozzles may be controlled simultaneously.

The clothes care apparatus may include a case 10 and an air supply unit 20, a dust removing unit 30, a steam supply unit 50, a perfume supply unit 60, a dehumidifying unit (not shown), and the like.

The exhaust port 14b is provided on the upper side of the second partition 15. The exhaust duct 44 connects the exhaust port 14b and the dust container 41. [ Foreign matter such as dust that has passed through the exhaust port 14b passes through the exhaust duct 44 and then moves to the dust container 41. [

A plurality of discharge nozzles (23-27) are installed in the second partition (15) so that at least one portion thereof is exposed in the clothes receiving chamber (17). The plurality of discharge nozzles 23-27 are arranged so as to be upwardly inclined in the direction toward the door 11. [ The air ejected from the plurality of ejection nozzles 23-27 is injected with an upward slope.

The plurality of opening / closing valves 33-37 opens / closes the airflow ejected from the plurality of ejection nozzles 23-27. The control unit 100 controls the plurality of on-off valves 33-37 to sequentially operate the plurality of discharge nozzles 23-27. That is, air is sequentially jetted from the plurality of discharge nozzles 23-27. For example, air is sprayed first from the fifth discharge nozzle 27 disposed at the lowermost side of the first partition 14, air is sprayed next from the fourth discharge nozzle 26 disposed thereon, Air is sequentially injected from the third ejection nozzle 25 and the second ejection nozzle 24 disposed on the first ejection nozzle 24 and the air is finally ejected from the first ejection nozzle 23 disposed on the uppermost side.

The fifth opening / closing valve 37 located at the lowermost position of the second partition 15 is opened to inject air from the fifth discharge nozzle 27. At this time, the other on-off valves 23-26 are all closed. Since the fifth discharge nozzle 27 is upwardly inclined, the air injected from the fifth discharge nozzle 27 is also sprayed upward. Therefore, the foreign matter separated from the clothes by the air ejected from the fifth ejection nozzle 27 moves upward.

Thereafter, the fourth on-off valve 36 is opened to inject air from the fourth discharge nozzle 26. At this time, the other on-off valves 33, 34, 35 and 37 are all closed. Since the fourth discharge nozzle 26 also has an upward slope, the air injected from the fourth discharge nozzle 26 is also sprayed upward. Therefore, the foreign matter separated from the clothes by the air ejected from the fourth ejection nozzle 26 moves upward. In addition, the air ejected from the fourth ejection nozzle 26 moves the foreign matter moving upward in the upward direction by the fifth ejection nozzle 27 as well.

In this manner, the third on-off valve 35 and the second on-off valve 34 are sequentially opened and the third discharge nozzle 25 and the second discharge nozzle 24

Allow air to be sprayed. The foreign matter gradually rises to the upper side of the clothes accommodating chamber 17 by the third ejection nozzle 25 and the second ejection nozzle 24. [

Thereafter, the first on-off valve 33 is opened so that air is jetted from the first discharge nozzle 23. At this time, the other on-off valves 34-37 are all closed. Since the first discharge nozzle 23 also has an upward slope, the air injected from the first discharge nozzle 23 is also sprayed upward. Therefore, the foreign matter separated from the clothes is moved upward by the air ejected from the first ejection nozzle 23, and the foreign matter moving upward by the other ejection nozzles 24-27 also moves upward. Eventually, the foreign matter passes through the exhaust port 14b disposed on the upper side, and is then stored in the dust container 41 through the exhaust duct 44. [

As shown, the clothes care apparatus includes a case 10, an air supply unit 20, a dust removing unit 40, a steam supply unit 50, a perfume supply unit 60, a dehumidifying unit (not shown) And the like.

The first partition 14 of the case 10 is provided laterally to partition the inner space of the case 10 up and down and the machine room 16 is provided below the case 10. The machine room 16 is provided with an air pump 21, a dust container 41, a water container 51, and a fragrance container 61.

The second partition 15 of the case 10 is vertically installed to partition the inner space of the case 10 to the left and right. A duct chamber 18 is provided on the left side of the second partition 15 and a clothes receiving chamber 17 is provided on the right side. The duct chamber (18) is provided with an injection duct (22) and an exhaust duct (44). The injection duct (22) and the exhaust duct (44) are branched into a plurality of discharge nozzles (23-27) corresponding to the plurality of discharge nozzles (23-27).

A plurality of discharge nozzles (23-27) are installed in the second partition (15) so that at least one portion thereof is exposed in the clothes receiving chamber (17). Each of the plurality of ejection nozzles 23-27 may be configured to include ejection nozzles 23a-27a and exhaust ejection nozzles 23b-27b. The spray ejection nozzles 23a-27a are located at the center, and the exhaust ejection nozzles 23b-27b are positioned so as to surround the outer periphery of the ejection nozzles 23a-27a. The injection nozzles 23a to 27a are connected to the injection duct 22 and the exhaust discharge nozzles 23b to 27b are connected to the exhaust duct 44. [

The plurality of on-off valves 33-37 opens and closes the air flow ejected from the plurality of ejection nozzles 23a-27a. The control unit 100 controls the plurality of on-off valves 33-37 so that the plurality of spray nozzles 23a-27a are operated one by one.

That is, when air is ejected from any of the plurality of ejection nozzles 23a-27a, air is not ejected from the other ejection nozzles. Further, the discharge nozzle through which the air is sprayed can be arbitrarily selected. That is, the plurality of spray nozzles 23a-27a may be operated in order along the upper or lower direction, and may be operated randomly regardless of the order.

The control unit 100 opens the plurality of on-off valves 33-37 and blows air into the clothes storage chamber 17 to blow off dust and other foreign substances on the clothes.

More specifically, the control unit 100 opens the third on-off valve 35 positioned at the center of the second partition 15 so that air is jetted from the third jetting nozzle 25a. At this time, all of the other spray ejection nozzles 23a, 24a, 26a, 27a are closed. The air sprayed from the third spray ejection nozzle 25a shakes off the foreign substances on the clothes, and the floating foreign matter is sucked through the third exhaust ejection nozzle 25b. At this time, the foreign matter can also be sucked through the other exhaust ejection nozzles 23b, 24b, 26b, 27b. However, it is possible to provide another on / off valve in the third exhaust discharge nozzle 25b in order to suck it only through the third exhaust discharge nozzle 25b.

Thereafter, the first on-off valve 33 is opened to inject air from the first spray injection nozzle 23a. At this time, the other on-off valves 34-37 are all closed. The air ejected from the first ejection nozzle 23a blows foreign substances on the clothes, and the floating foreign matter can be sucked through the ejection nozzles 23b-27b.

Thereafter, the fifth open / close valve 37 is opened to inject air from the fifth spray ejection nozzle 27a. At this time, the other on-off valves 33-36 are all closed. The air sprayed from the fifth spray ejection nozzle 27a blows away foreign substances on the clothes, and the floating foreign matter can be sucked through the exhaust ejection nozzles 23b-27b.

Thus, the second on-off valve 34 and the fourth on-off valve 36 are also opened in the same manner, so that the air is jetted from the second jetting nozzle 24a and the fourth jetting nozzle 26a. Foreign substances floating by the injected air can be sucked through the exhaust discharge nozzles 23b-27b.

As a result, the control unit 100 can open and close the plurality of open / close valves 33-37 in a random manner without any order, so that the plurality of spray nozzles 23a-27a can be operated. The clothes care apparatus shown in the figure sequentially opens and closes a plurality of open / close valves 33-37 from the upper side to the lower side or from the lower side to the upper side. However, the clothes care apparatuses may be provided with a plurality of open / close valves 33-37 Can be opened.

The foreign matter sucked through the exhaust discharge nozzles 23b-27b moves to the dust container 41 through the exhaust duct 44. [ And then separated and stored in the dust container (41). Further, the foreign matter detection sensor 70 may be installed in the exhaust duct 44 or the exhaust discharge nozzles 23b-27b

All. The foreign matter detection sensor 70 measures the amount of dust passing through the exhaust duct 44 or the exhaust discharge nozzles 23b-27b. The foreign substance detection sensor 70 provides the dust measurement value to the control unit 100. The control unit 100 compares the dust measurement value with a reference value and determines the air injection pressure or the air sprayed from the plurality of spray ejection nozzles 23a- Adjust the number of injections. That is, when the dust measurement value is larger than the reference value, the controller 100 may increase the air injection pressure or increase the air injection number. Conversely, when the dust measurement value is smaller than the reference value, the air injection pressure can be lowered or the number of air injections can be reduced.

The moisture in the clothes receiving chamber 17 is removed through a dehumidifying unit (not shown). Because the moisture contained in the clothes is eliminated, the clothes have a stiff effect.
