The present disclosure relates to an air flow path structure in a clothes treatment apparatus.
A clothes treatment apparatus refers to all kinds of apparatuses for maintaining or treating clothes, such washing, drying, and dewrinkling them, at home or at a laundromat. Examples of clothes treatment apparatuses include a washer for washing clothes, a dryer for drying clothes, a washer-dryer which performs both washing and drying functions, a refresher for refreshing clothes, and a steamer for removing unnecessary wrinkles in clothes.
More specifically, the refresher is a device used for keeping clothes crisp and fresh, which performs functions like drying clothes, providing fragrance to clothes, preventing static cling on clothes, removing wrinkles from clothes, and so on. The steamer is generally a device that provides steam to clothes to remove wrinkles from them, which can remove wrinkles from clothes in a more delicate way, without the hot plate touching the clothes like in traditional irons. There is a known clothes treatment apparatus equipped with both the refresher and steamer functions, that functions to remove wrinkles and smells from clothes put inside it by using steam and hot air.
There is also a known apparatus that comes with a rack for hanging clothes in a treatment chamber, and that provides steam into the treatment chamber where the clothes are hung or provides hot air while circulating the air in the treatment chamber.
One of the problems with the conventional art is that it only allows limited functional versatility when it comes to combining each component's functions and various air flow paths. A first aspect of the present disclosure is to solve this problem.
Another problem with the conventional art is that it is difficult to remove ultrafine dust clinging to clothes. A second aspect of the present disclosure is to solve this problem.
A third aspect of the present disclosure is to provide a clothes treatment apparatus with greater functional versatility by providing outside air to clothes as necessary.
A fourth aspect of the present disclosure is to provide an efficient structure for controlling the change of flow paths.
A fifth aspect of the present disclosure is to help the user easily replace and wash a filter and prevent filter failures.
A sixth aspect of the present disclosure is to allow for easy removal of a replaceable filter and at the same time to protect it at normal times.
A seventh aspect of the present disclosure is to provide an efficient structure that can function on air passing through various flow paths.
In order to address the aforementioned aspects, a clothes treatment apparatus according to an exemplary embodiment of the present disclosure comprises: a cabinet forming a treatment space for storing clothes; a filter module having a filter portion for filtering out dust from air passing therethrough; an air flow path having a plurality of preset flow paths for directing air to be discharged into the treatment space; a fan for moving the air in the air flow path; at least one valve disposed on the air flow path; a valve actuating module for actuating the valve; and a control part for controlling the valve actuating module so as to select one of the plurality of flow paths.
The plurality of flow paths may comprise: at least one bypass flow path for directing the air to bypass the filter portion; and at least one filtering flow path for directing the air to pass through the filter portion.
The plurality of flow paths may comprise: at least one circulation flow path for directing air drawn in from inside the treatment space; and at least one ventilation flow path for directing air drawn in from an outer space of the cabinet.

The clothes treatment apparatus may further comprise a steam module for supplying steam into the treatment space, and the filter portion may comprise a HEPA filter.
The bypass flow path may be configured to direct air drawn in from inside the treatment space. The control part may be configured to select one of a plurality of preset modes. The plurality of modes may comprise: a bypass mode in which the steam module sprays steam into the treatment space, the fan is operating, and the bypass flow path is selected from among the plurality of flow paths; and a filtering mode in which the steam mode does not spray steam into the treatment space, the fan is operating, and the filtering flow path is selected from among the plurality of flow paths.
The fan may be disposed in a shared section which commonly constitutes part of the bypass flow path and part of the filtering flow path. The clothes treatment apparatus may further comprise a heat exchange module which is disposed in the shared section and heats or cools air.
The at least one bypass flow path may comprise a bypass circulation flow path for directing air drawn in from inside the treatment space. The at least one filtering flow path may comprise a filtering circulation flow path for directing the air drawn in from inside the treatment space.
The at least one filtering flow path may further comprise a ventilation flow path for directing air drawn in from an outer space of the cabinet.
The clothes treatment apparatus may further comprise: an outer intake portion forming an outside air inlet section which constitutes an upstream end of the ventilation flow path and is configured to open and close; and an outer discharge portion forming an exhaust air outlet section which is disposed between the treatment space and the outer space and configured to open and close.
The at least one valve may comprise: a first valve disposed on the bypass flow path to open and close the flow path; and a second valve disposed on the filtering flow path to open and close the flow path. The valve actuating module may comprise a single motor that provides torque to open and close the first valve and the second valve.
The valve actuating module may be configured in such a way as to select one of a plurality of modes including a first mode in which the first valve is opened and the second valve is closed, a second mode in which the first valve is closed and the second valve is opened, and a third mode in which both the first valve and the second valve are closed.
The valve actuating module may comprise: a first valve connecting portion connected to the first valve so that the first valve rotates together with the rotation of the first valve connecting portion around a predetermined, first rotational axis; a second valve connecting portion connected to the second valve so that the second valve rotates together with the rotation of the second valve connecting portion around a predetermined, second rotational axis; and a valve regulating portion configured to rotate around a predetermined central axis, powered by the motor, and to rotate either the first valve connecting portion or the second valve connecting portion depending on the angle of rotation.
A first gear portion of the first valve connecting portion and a second gear portion of the second valve connecting portion may be positioned at the same distance from the central axis, and the valve regulating portion may comprise a driving gear portion configured to mesh with either the first gear portion or the second gear portion depending on the angle of rotation.
The first valve connecting portion may comprise a first gear portion, and the second valve connecting portion may comprise a second gear portion. The valve regulating portion may comprise a driving gear portion formed along the direction of rotation within the range of a predetermined angle Ag2 with respect to the central axis. The angle Ag1 formed between the first rotational axis and the second rotational axis with respect to the central axis may be greater than the angle Ag2.
The first gear portion and the second gear portion may have the same shape, and the first rotational axis and the second rotational axis may be positioned at the same distance d from the central axis.
The valve actuating module may comprise a power transmitting portion that transmits the torque of the motor to the valve regulating portion.
The power transmitting portion may comprise a worm gear fixed to the motor shaft of the motor to rotate. The valve regulating portion may further comprise a driven gear portion meshing with the worm gear.
The valve actuating module may comprise a constraining portion that restricts the range of rotation of the valve regulating portion.
The constraining portion may comprise: a first constraining portion that limits the maximum value for rotation of the valve regulating portion in a first direction; and a second constraining portion that limits the maximum value for rotation of the valve regulating portion in a second direction. When the valve regulating portion is fully rotated in the first direction, the first valve may be opened, and when the valve regulating portion is fully rotated in the second direction, the second valve may be opened.
The filter module may be configured in such a way as to be pulled out in a direction across the filtering flow path. The filter module may further comprise a cover that covers a side where the filter module is pulled out and that is removably placed on the cabinet.
The cover may form an inner intake opening through which air is admitted to the bypass flow path and the filtering flow path. The cover may further comprise an auxiliary filter removably placed between the filter module and the cover and comprising an auxiliary filter portion which filters out impurities from the air moving to the bypass flow path and filtering flow path through the inner intake opening but is functionally different from the filter portion.
The cover may form at least part of the inner intake opening through which air is admitted to the bypass flow path and the filtering flow path. The cover may comprise a fragrance sheet.
The clothes treatment apparatus is advantageous in that it can implement more various and diverse functions by switching between flow paths.
Another advantage is that it can remove impurities from air supplied into the treatment space when necessary, taking into consideration the effect of air on the filter portion, by including the bypass flow path and the filtering flow path.
Also, fresh air can be supplied to clothes by including a ventilation flow path. A further advantage is that the effect on the air around the clothes treatment apparatus can be taken into consideration since the ventilation flow path can be selected.
By disposing the fan and the heat exchange module in the shared section, whichever one of the plurality of flow paths is selected may move the air in the flow path by operating a single fan and heat or cool the air in the flow path by means of a single heat exchange module.
By including the filtering flow path and the bypass flow path, in addition to the steam module and the HEPA filter, the high-performance functions of the HEPA filter can be employed, and steam can be guided not to pass through the HEPA when supplied into the treatment space through the steam module.
In the bypass mode, by spraying steam into the treatment space and selecting the bypass flow path, an air treatment can be done while circulating the air in the treatment space, without allowing the steam supplied to the treatment space to pass through the filter portion.
By making the predetermined angle Ag1 greater than the angle Ag2, either the first valve connecting portion or the second valve connecting portion can be rotated depending on the angle of rotation of the valve regulating portion.
By positioning the first gear portion and the second gear portion at the same distance from the central axis, both the first gear portion and the second gear portion can be manipulated by the single driving gear portion.
By forming the first gear portion and the second gear portion in the same shape and positioning the first rotational axis and the second rotational axis at the same distance d from the central axis, both the first gear portion and the second gear portion can be manipulated by the single driving gear portion.
By including the constraining portion, the positions of the first valve and second valve can be easily controlled without using a hole sensor.
By including the inner intake opening and the fragrance sheet in the cover, fragrance can be added efficiently to both the air passing through the bypass flow path and the filtering flow path.
By including the auxiliary filter, a filtering function can be added to both the bypass flow path and the filtering flow path.

In the ventilation mode, the control part 2 controls the fan 50 to bring it into operation. In the ventilation mode, the control part 2 controls the valve actuating module 80 so as to select the ventilation flow path Pc from among the plurality of flow paths.
When the ventilation mode is selected, the ventilation flow path Pc is selected from among the plurality of flow paths. When the ventilation flow path Pc is selected, the control part 2 controls in such a way that the outer intake portion 47 and the outer discharge portion 48 are opened. That is, the outer intake portion 47 opens the outside air inlet section P4, and the outer discharge portion 48 opens the exhaust air outlet section P5.
The plurality of modes may comprise a bypass circulation mode, a filtering circulation mode, and a ventilation mode. The plurality of modes may be selected through the user's input using the input part 3. The plurality of modes may be selected and performed at different time slots in a single clothes treatment process. The plurality of modes may be selected and performed differently based on information sensed by the sensing part 4.
In the bypass circulation mode, the control part 2 controls the steam module 7 to spray steam into the treatment space 10s. In the bypass circulation mode, the control part 2 controls the fan 50 to bring it into operation. In the bypass circulation mode, the control part 2 controls the valve actuating module 80 so as to select the bypass circulation flow path Pa from among the plurality of flow paths. In the bypass circulation mode, the control part 2 controls in such a way that the first valve 70a is opened and the second valve 70b is closed. In the bypass circulation mode, the control part 2 controls in such a way that the outer intake portion 47 and the outer discharge portion 48 are closed. The bypass circulation mode can facilitate efficient supply of steam to clothes.
In the filtering circulation mode, the control part 2 controls the steam module 7 not to spray steam into the treatment space 10s. In the filtering circulation mode, the control part 2 controls the fan 50 to bring it into operation. In the filtering circulation mode, the control part 2 controls the valve actuating module 80 so as to select the filtering circulation flow path Pb from among the plurality of flow paths. In the filtering circulation mode, the control part 2 controls in such a way that the first valve 70a is closed and the second valve 70b is opened. In the filtering circulation mode, the control part 2 controls in such a way that the outer intake portion 47 and the outer discharge portion 48 are closed. In the filtering circulation mode, the control part 2 may control the hanger module 30 so as to make it vibrate. The filtering circulation mode allows for efficient removal of impurities clinging to clothes.
In the bypass circulation mode and the filtering circulation mode, the control part 2 may vary the vibration pattern of the hanger module 30. In an example, the control part 2 may control the hanger module 30 to vibrate relatively slowly in the bypass circulation mode and relatively fast in the filtering circulation mode.
In the ventilation mode, the control part 2 may control the steam module 7 not to spray steam into the treatment space 10s. In the ventilation mode, the control part 2 controls the fan 50 to bring it into operation. In the ventilation mode, the control part 2 may control the valve actuating module 80 so as to select the ventilation flow path Pc from among the plurality of flow paths. In the ventilation mode, the control part 2 controls in such a way that the first valve 70a is closed and the second valve 70b is closed. In the ventilation mode, the control part 2 controls in such a way that the outer intake portion 47 and the outer discharge portion 48 are opened. In the ventilation mode, the control part 2 may control the hanger module 30 not to vibrate. The ventilation mode allows for efficient removal of humidity or odorous components in clothes. Moreover, in the ventilation mode, dust or odorous components in the treatment space 10s may be released to the outside, thereby improving the quality of the space in which clothes are stored.
