Description

Garment processing equipment

[0001] The present invention relates to a clothing treatment device.

[0002] A garment treatment device refers to a washing machine, which washes items like clothing through a washing cycle, and a dryer, which dries items through a drying cycle. While washing machines and dryers are typically installed as separate units, there are garment treatment devices that can perform both washing and drying simultaneously to overcome space constraints and enhance user convenience.

[0003] In order to execute the washing process, the clothing treatment device is provided with a cabinet, a tub for storing water, a drum providing a space for accommodating the subject of treatment, a driving unit fixed to the tub and rotating the drum, a support unit for supporting the tub, a water supply unit for supplying water to the tub, and a drain unit for draining water from the tub.

[0004] Meanwhile, in order to execute the drying process, the clothing treatment device is equipped with a flow path for extracting air from inside the tub and resupplying it to the tub, and a heat exchanger provided in the flow path for sequentially performing dehumidification and heating of the air.

[0005] That is, among the conventional clothing treatment devices, there were some that were all installed with devices for both the washing cycle and the drying cycle inside the cabinet, so that the user could selectively perform the washing cycle and the drying cycle according to his or her convenience.

[0006] The conventional garment treatment device having the structure described above has a problem in that it is difficult to apply it to a commercial garment treatment device that must frequently and quickly process a large number of objects to be treated.

[0007] In the case of commercial clothing treatment equipment, it is common for it to be equipped to process a larger quantity of clothing than a home clothing treatment equipment or to process heavy clothing such as blankets.

[0008] Therefore, commercial garment processing equipment requires processing space to accommodate heavy, bulky garments simultaneously, and a heat exchanger for rapid washing and drying. Therefore, it has been difficult to install both washing and drying equipment in a cabinet with limited space. While it is possible to install both washing and drying equipment by designing the cabinet to be larger, this presents challenges in terms of manufacturing and transportation. Therefore, the coupling and arrangement of washing and drying equipment has been a key design consideration for commercial garment processing equipment.

[0009] In addition, since the drying process for a large amount of clothing is performed, the amount of hot air discharged and supplied increases, which increases the amount of foreign substances such as lint, which accumulate in the heat exchanger and reduce the heat transfer area, which can easily lead to a decrease in drying performance, so the importance of the filter is emphasized.

[0010] However, in light of the special characteristics of commercial dryers, it is difficult to ensure structural robustness with the filters provided in existing general dryers, and the accessibility of the filters makes it difficult to periodically check their status and clean them.

[0011] Therefore, combining and arranging the filter in a garment treatment device so that it can be easily replaced and removed is an important task in the present technical field.

[0012] The present application aims to solve the problem of providing a clothes treatment device equipped with a filter that is easy to replace and repair.

[0013] The present application aims to solve the problem of providing a clothing treatment device equipped with a filter having improved structural robustness.

[0014] The present application aims to provide a garment treatment device equipped with a filter that improves maintainability by visually checking the degree of lint deposition.

[0015] The present application aims to provide a clothing treatment device in which multiple filters are optimally arranged to increase space utilization.

[0016] The present application aims to solve the problem of providing a clothing treatment device that facilitates the withdrawal and introduction of a filter.

[0095] In addition, terms such as “front,” “rear,” “upper,” “lower,” “side,” “front end,” “rear end,” “top,” and “bottom” used in this specification are defined based on the drawings or defined based on the configuration or arrangement / arrangement state between configurations, and the shape and position of each configuration are not limited by these terms.

[0096] Hereinafter, a preferred embodiment of a garment treatment device and its control method will be described in detail with reference to the attached drawings.

[0097] As illustrated in FIG. 1, a clothing treatment device (100) may be equipped to include a first treatment device (100a, treatment module, washing module) that provides a space for washing or drying a treatment target such as clothing, and a second treatment device (100b, drying module, heat exchange module, detachable module) that is detachably coupled to the first treatment device (100a) for drying a treatment target put into the first treatment device (100a).

[0098] The first treatment device (100a) may be provided to include a first cabinet (1), and the second treatment device (100b) may be provided to include a second cabinet (6). As shown in the drawing, the second treatment device (100b) may be provided to be positioned above the first treatment device (100a), and in this case, the exterior of the clothing treatment device (100) may be formed by the first cabinet (1) and the second cabinet (6).

[0099] The above first treatment device (100a) can be installed independently to perform a washing cycle, and when the second treatment device (100b) is combined therewith, it can be equipped to perform a drying cycle capable of removing moisture from the clothing.

[0100] Accordingly, the clothing treatment device of the present invention can utilize the first treatment device (100a) as a washing machine when the first treatment device (100a) is independently provided, and can utilize the clothing treatment device (100) as both a washing machine and a dryer when the first treatment device (100a) and the second treatment device (100b) are provided together.

[0101] As a result, depending on the user's situation and choice, only the first processing device (100a) may be installed, or the second processing device (100b) may be installed by combining it with the first processing device (100a).

[0102] In particular, when the first treatment device (100a) is equipped to process a large amount of clothing, such as a commercial clothing treatment device, and thus has a larger overall volume than a home clothing treatment device, the option to selectively combine the second treatment device (100b) may be more useful to any user who may have installation space constraints.

[0103] In addition, since the second processing device (100b) is provided separately from the first processing device (100a), the size, volume, and weight of the first processing device (100a) can be prevented from becoming excessive, and the process of manufacturing the first processing device (100a) and the second processing device (100b) and the process of installing or transporting the first processing device (100a) and the second processing device (100b) can also be facilitated.

[0104] The first cabinet (1) may be provided to include a front panel (11, first front panel) that forms the front surface of the first processing device (100a), a side panel (12, first side panel) connected to the first front panel to form a side surface of the first processing device (100a), and a rear panel (13, first rear panel) that is provided at a position facing the first front panel (11) to form the rear surface of the first processing device (100a).

[0105] The first front panel (11) may be provided with a control panel (112) for controlling the clothing treatment device (100). The control panel (112) may be provided to control only one of the first treatment device (100a) and the second treatment device (100b), or may be provided to control both the first treatment device (100a) and the second treatment device (100b).

[0106] As illustrated in Fig. 2, the first front panel (11) may be provided with a first panel body (113) and a second panel body (114). The first panel body (113) may be provided as a panel fixed to the first processing device (100a) to form a mounting space for the control panel (112), and the second panel body (114) may be provided as a panel detachable from the first processing device (100a).

[0107] The first panel body (113) is provided to include a cabinet penetration hole (111) that communicates with the inside of the first processing device (100a), and the second panel body (114) can be provided at a position where at least some of the components provided inside the first processing device (100a) can be exposed to the outside of the first processing device (100a).

[0108] The second panel body (114) may be detachably provided below the first panel body (113). Even if a wall or other home appliance is placed on the side of the first cabinet (1), the second panel body (114) can be detached and attached regardless of this.

[0109] When the second panel body (114) is separated, at least a part of the electrical components placed inside the first cabinet (1) can be checked, repaired, or replaced.

[0110] FIG. 2 illustrates an example in which the first panel body (113) forms the upper region of the first front panel (11), and the second panel body (114) forms the lower region of the first front panel (11).

[0111] The first side panel (12) may be provided to include a left panel (121, first left panel) forming the left side of the first processing device (100a) (part of the left side of the garment processing device), and a right panel (122, first right panel) forming the right side of the first processing device (100a) (part of the right side of the garment processing device).

[0112] The first processing device (100a) may be provided with a mounting space (15) to which the second processing device (100b) is fixed. The mounting space (15) may be provided as an open space formed on the upper surface of the first cabinet (1). FIG. 2 illustrates an example in which the mounting space (15) is formed by the upper portion of the first front panel (11), the upper portion of the first left panel (121), the upper portion of the first right panel (122), and the upper portion of the first rear panel (13).

[0113] The height of the first front panel (11) and the height of the first rear panel (13) can be set higher (H) than the height of the first left panel (121) and the height of the first right panel (122). When the heights of the first front panel (11) and the first rear panel (13) are set higher than the side panels (121, 122), not only is it advantageous for positioning and fixing the second treatment device (100b) when mounting it in the mounting space (15), but there is also an effect of reducing the height of the entire garment treatment device (100).

[0114] In addition, if the first front panel (11) is set higher than the side panels (121, 122), it will be possible to form a space in the first front panel (11) where other devices (devices such as detergent storage units) can be installed, while minimizing the increase in the height of the clothing treatment device (100). The lower surface of the second cabinet (6) and the upper surface of the first cabinet (1) can be properly coupled to each other without a space being separated.

[0115] Accordingly, when the second cabinet (6) is installed in the first cabinet (1), the first cabinet (1) and the second cabinet (6) can be arranged parallel in the height direction, and an effect similar to that of the second cabinet (6) extending vertically from the first cabinet (1) can be obtained.

[0116] In addition, moisture or outside air can be prevented from entering the joint portion of the second cabinet (6) and the first cabinet (1).

[0117] A first control unit (19) for controlling at least one of the first processing device (100a) and the second processing device (100b) may be provided inside the first cabinet (1). The first control unit (19) may be provided to receive a control signal from the input unit of the control panel (112) or to transmit a control signal requesting the display of information on the display unit of the control panel (112). It may be fixed to the first rear panel (13).

[0118] The first cabinet (1) may be provided with a receiving portion (3) that forms a washing space and a drying space for the subject matter to be treated. Fig. 3 illustrates an example in which the receiving portion (3) is provided with a tub (3a) that forms a space for storing water and a path for moving air, and a drum (3b) that is rotatably provided inside the tub (3a) to form a space for receiving the subject matter to be treated.

[0119] The above tub (3a) may be provided to include a tub body (30) that provides a space for storing water and is fixed inside the first cabinet (1) via a tub support member (34).

[0120] The above tub body (30) may be provided in a cylindrical shape with an empty interior. The tub body (30) may be provided to include a tub front surface (31) provided in a direction facing the first front panel (11), a tub rear surface (31a) provided in a direction facing the first rear panel (13), and a tub circumferential surface (31b) connecting the tub front surface (31) and the tub rear surface (31a).

[0121] The front surface (31) of the tub may be provided with a tub inlet (311) communicating with the inside of the drum (3b), and a connecting body (312) that is provided in a shape that surrounds the tub inlet (311) and protrudes from the front surface (31) of the tub toward the cabinet penetration hole (111).

[0122] That is, the connecting body (312) is provided as a cylinder protruding from the front surface (31) of the tub toward the first front panel (11), and the tub inlet (311) is provided as a hole penetrating the front surface (31) of the tub, but may be provided so as to be located inside the connecting body (312).

[0123] The above-mentioned connecting body (312) not only provides a mounting space for the injection unit or tub air supply unit (35a) described later, but can also serve as a means for guiding the treatment target fed into the drum (3b) through the cabinet penetration hole (111) to the tub inlet (311).

[0124] When the door (2) is coupled to the first cabinet (1) and is provided to open and close the tub inlet (311), the vibration of the tub (3a) may be transmitted to the door (2) and the first cabinet (1). At this time, when the tub (3a) is made of a metal material and is heavy in itself, and a large amount of water and clothes are stored in the tub (3a), the door (2) and the first cabinet (1) may not be able to stably support the force and vibration transmitted from the tub (3a).

[0125] Accordingly, the garment treatment device of the present invention can install the door (2) in the tub (3a). When the door (2) is coupled to the tub (3a), the door (2) vibrates integrally with the tub (3a), so that the door (2) can be prevented from being broken or damaged by the vibration of the tub (3a).

[0126] In addition, since the position where the door (2) opens and closes the tub inlet (311) is fixed, even if the tub (3a) vibrates, the door (2) can stably seal the tub inlet (311).

[0127] That is, the tub inlet (311) can be opened and closed by a door (2) rotatably fixed to the front surface (31) of the tub. As illustrated in FIG. 2, since the door (2) is not rotatably fixed to the first front panel (11) but is rotatably fixed to the tub body (30), it is preferable that the cabinet penetration hole (111) be provided in a size and position that does not interfere with the rotation of the door (2) (rotation for opening or closing the inlet).

[0128] When the tub inlet (311) is closed, the door (2) remains exposed to the outside of the first cabinet (1) through the cabinet penetration hole (111). However, when the tub inlet (311) is opened, the door (2) can rotate toward the outside of the first cabinet (1) through the cabinet penetration hole (111).

[0129] As illustrated in Fig. 3, in order to fix the door (2) to the front surface (31) of the tub, the tub (3a) may be provided with a door mounting portion (T / D). The door mounting portion (T / D) may be provided to include a first mounting cover (32) fixed to the front surface (31) of the tub and surrounding the connecting body (312), and a second mounting cover (33) fixed to the first mounting cover (32) and to which the hinge (27) of the door is mounted.

[0130] In order to prevent the tub inlet (311) from being closed by the door mounting part (T / D), a first inlet communication hole (322) communicating with the tub inlet (311) may be formed in the first mounting cover (32), and a second inlet communication hole (334) communicating with the tub inlet (311) and the first inlet communication hole (322) may be formed in the second mounting cover (33).

[0131] The above tub (3a) can be connected to the second treatment device (100b) via the tub air supply part (35a) and the tub exhaust part (35b). That is, the second treatment device (100b) can be detachably connected to the tub air supply part (35a) and the tub exhaust part (35b).

[0132] The above tub air supply unit (35a) may be provided to supply air into the inside of the tub body (30) through the connecting body (312), and the above tub exhaust unit (35b) may be provided to discharge air inside the tub body (30) to the outside of the tub (3a) through the tub circumference (31b).

[0133] The above tub air supply unit (35a) may be provided to include a first air supply hole (351) and a second air supply hole (352) provided in the connecting body (312), and a distribution pipe (353) that guides air to each of the air supply holes (351, 352).

[0134] The first air supply hole (351) and the second air supply hole (352) may be provided to penetrate the connection body (312) and communicate with the tub inlet (311). The distribution pipe (353) may be provided to include a connection pipe (353a) connected to the second treatment device (100b), a first branch pipe (353b) that guides some of the air introduced into the connection pipe (353a) to the first air supply hole (351), and a second branch pipe (353c) that guides some of the air introduced into the connection pipe (353a) to the second air supply hole (352).

[0135] In order for the above-mentioned clothing treatment device (100) to perform washing or drying of a large number of items to be treated, the volume of the tub body (30) and the volume of the drum (3b) need to be designed to be large. Since the drum (3b) must be supported by the rear surface (31a) of the tub and be rotatable within the tub body (30), the durability of the tub body (30) is important in order to design the volume of the drum (3b) to be large. Therefore, the tub body (30) may be formed of a metal material.

[0136] When the tub body (30) is made of a metal material, it is preferable that the connection body (312) is also made of a metal material, and the distribution pipe (353) may be made of a different material from the connection body (312). The distribution pipe (353) provided with the first branch pipe and the second branch pipe described above may be advantageous in terms of cost and time to be formed of a material such as plastic rather than metal. Therefore, when the distribution pipe (353) and the connection body (312) are made of different materials, the first treatment device (100a) may further include a bracket (354) that connects the distribution pipe (353) to the connection body (312).

[0169] The above first processing device (100a) may be provided with a communication part (59, external air communication part) that can supply external air into the inside of the tub body (30) or supply external air to the tub body (30).

[0170] Water may remain in the tub body (30) and drum body (36), and the clothing treatment device (100) equipped with the communication part (59) has the effect of enabling hygienic management of the tub (3a) and the drum (3b) by reducing the possibility of water remaining in the tub body (30) and drum body (36).

[0171] In addition, the clothing treatment device (100) equipped with the above-mentioned connecting portion (59) can prevent the inside of the tub body (30) from being sealed even when the door (2) closes the tub inlet (311). Therefore, the clothing treatment device (100) can prevent an accident that may occur due to the tub body (30) being sealed.

[0172] In order to prevent the fluid (water, foam, foreign matter) inside the tub body (30) from being discharged to the outside of the first cabinet (1) through the above-mentioned communication portion (59), the first treatment device (100a) may be provided with a connecting portion (56) that connects the flow path formed by the water supply portion (5) and the flow path formed by the communication portion (59).

[0173] As shown in FIG. 6 and FIG. 7, the first processing device (100a) may be equipped with a spray unit (4a, 4b).

[0174] The above-mentioned spray unit (4a, 4b) may be provided to include at least one of a first washing unit (4a) that is fixed to the connecting body (312) and sprays water onto the door (2) and a second washing unit (4b) that is fixed to the connecting body (312) and sprays water into the inside of the drum (3b).

[0175] Each of the first washing unit (4a) and the second washing unit (4b) may be equipped to spray water supplied from the water source, or may be equipped to spray water inside the tub body (30). The first washing unit (4a) may be equipped to spray water supplied from the water source, and the second washing unit (4b) may be equipped to spray water inside the tub body (30).

[0176] When the first washing unit (4a) is equipped to spray water supplied from the water source, the first washing unit (4a) can receive water through a nozzle supply pipe connected to the spray unit supply path.

[0177] The above first processing device (100a) may be equipped with a temperature detection sensor (318) for temperature measurement, and the connecting body (312) may be equipped with a mounting hole (317) in which the temperature detection sensor (318) is mounted.

[0178] The above temperature detection sensor (318) may be provided to measure at least one of the temperature inside the drum body (36), the temperature of the processing target inside the drum body, and the temperature of the air supplied from the second processing device (100b). An infrared temperature sensor that measures the temperature of the processing target by detecting infrared rays emitted from the processing target may be an example of the temperature detection sensor (318).

[0179] In order to measure the temperature inside the drum body (36), the temperature of the object to be processed, or the temperature of the air supplied to the tub body (30), it is preferable that the temperature detection sensor (318) be provided in the upper region of the connection body (312).

[0180] The second washing unit (4b) may be provided to include a circulation pump (45) that moves water inside the tub body (30), a circulation nozzle (46) that is fixed to the connection body (312) and sprays water toward the drum inlet (361), and a circulation path (47) that connects the circulation pump (45) and the circulation nozzle (46).

[0181] The above circulation pump (45) may be provided to include a pump chamber (451) that receives water inside the tub body (30) through the drain pipe (454), a pump drain pipe (454) that connects the pump chamber (451) to the circulation path (47), and a pump motor (453) that rotates a pump impeller located inside the pump chamber (451) to move water to the pump drain pipe (454).

[0182] The drain pipe (454), the pump chamber (451), and the pump motor (453) may be positioned in a space formed between the first support body (341) and the second support body (345). Therefore, when the second panel body (114) is separated from the first treatment device (100a), the pump chamber (451) and the pump motor (453) may be exposed to the outside of the first treatment device (100a). Meanwhile, considering the durability of the pump motor (453), it is preferable that the pump motor (453) be fixed to the first support body (341) and positioned between the first support body (341) and the second support body (345).

[0183] The above circulation nozzle (46) may be provided to include a first nozzle (46a) fixed to the connecting body (312) and positioned to the left of a vertical line passing through the center of the tub inlet (311), and a second nozzle (46b) fixed to the connecting body (312) and positioned to the right of the vertical line.

[0184] The first nozzle (46a) may be fixed to an area located between the highest point of the mounting pipe and a 90 degree counterclockwise point on the circumference of the connecting body (312), and the second nozzle (46b) may be fixed to an area located between the highest point of the mounting pipe and a 90 degree clockwise point on the circumference of the connecting body (512). Since the object to be treated is often located on the bottom surface of the drum body (36) during the washing cycle, if each nozzle (46a, 46b) is provided to spray water toward the bottom surface of the drum body (36) at a point higher than the horizontal line passing through the tub inlet (311), the washing power may be increased.

[0185] The above circulation path (47) may be provided to include a connector (471) connected to the pump drain pipe (454), a first circulation water supply pipe (476) that guides water flowing into the connector (471) to the first nozzle (46a), and a second circulation water supply pipe (477) that guides water flowing into the connector (471) to the second nozzle (46b).

[0186] The above connector (471) is a means for setting the injection point of the first nozzle (46a) and the injection point of the second nozzle (46b) to be the same.

[0187] The connector (471) may be provided to include a connector body (472) fixed to the second support body (345), a connector path (473) provided inside the connector body (472) and supplied with water through the pump drain pipe (454), a connector first drain pipe (474) that supplies water inside the connector path (473) to the first circulation water supply pipe (476), and a connector second drain pipe (475) that guides water inside the connector path (473) to the second circulation water supply pipe (477).

[0188] The connector body (472) may be fixed to one side of the second support body (345) via a connector bracket so as to be positioned at the lower portion of the tub inlet (311). Since the second support body (345) is connected to the first support body (341) via the damper (346) and the spring (347), when the drum body (36) vibrates, the second support body (345) will vibrate together with the tub body (30). Therefore, it is preferable that at least a portion of the pump drain pipe (454) be provided as a corrugated pipe.

[0189] In order to mount the first nozzle (46a) and the second nozzle (46b) to the connecting body (312), the connecting body (312) may be provided with a circulation nozzle mounting portion.

[0191] The second processing device (100b) may be provided to include a second cabinet (6), a flow path (7, 8) provided inside the second cabinet (6), and a heat exchanger (9) provided in the flow path to remove moisture from the air (dehumidify) or heat the air.

[0192] The second cabinet (6) may include a support frame (61) mounted on the first cabinet (1), a side panel (65, second side panel) fixed to the support frame (61) to form a side surface of the second cabinet, a rear panel (64, second rear panel) fixed to the support frame (61) to form a rear surface of the second cabinet, and an upper panel (66) fixed to the support frame (61) to form an upper surface of the second cabinet.

[0193] The second rear panel (64) may be provided with a panel exhaust port (641) that connects the inside of the second cabinet (6) with the outside. Accordingly, through the panel exhaust port (641), air inside the second cabinet (6) can be discharged to the outside, and outside air can be introduced into the inside of the second cabinet (6).

[0194] A frame panel (62) may be provided on the front surface of the above support frame (61). The frame panel (62) may be provided to form a space in which a portion of the above-described guiding section (7, 8) is supported.

[0195] Furthermore, the support frame (61) may be provided with a front panel (67, second front panel) forming the front surface of the second cabinet. The second front panel (67) may be provided in a shape that surrounds the frame panel (62) so that the frame panel (62) is not exposed to the outside. In addition, the second front panel (67) may be rotatably fixed to the support frame (61) or the frame panel (62) so that a user can easily access the frame panel (62).

[0196] When the second cabinet (6) is mounted on the first cabinet (1), the lower end of the second side panel (65) may be connected to the upper end of the first side panel (12) of the first processing device, and the lower end of the second rear panel (64) may be connected to the upper end of the first rear panel (13). Meanwhile, when the second cabinet (6) is mounted on the first cabinet (1), the second front panel (67) may be provided to be positioned on the same plane as the first front panel (11).

[0197] When the heights of the upper part of the second side panel (65) and the upper part of the second front panel (67) are set to be the same and the second cabinet (6) is fixed to the upper part of the first cabinet (1), a sense of unity can be formed.

[0198] The above frame panel (62) may be provided at the same height as the second front panel (67) and may be placed on top of the first front panel (11), or may be placed with its lower end lower than the second front panel (67) and at least part of it may be inserted into the first front panel (11).

[0199] As shown in Fig. 9, the support frame (61) may be provided to include a lower frame (611) that can be detachably coupled to the mounting space (15) of the first cabinet (1), an upper frame (617) positioned above the lower frame (611) to which the upper panel (66) is fixed, and a connecting frame (618) that connects the frames (611, 617).

[0200] The front surface of the support frame (61) is closed by the frame panel (62), both sides of the support frame (61) are closed by the second side panel (65), the upper surface of the support frame (61) is closed by the upper panel (66), and the rear surface of the support frame (61) can be closed by the second rear panel (64).

[0201] As mentioned above, the internal space of the first cabinet (1) is connected to the outside through the mounting space (15). In order to connect the internal space of the first cabinet (1) and the internal space of the support frame (61), a communication space (612) connected to the mounting space (15) may be provided on the bottom surface of the support frame (61).

[0202] The support frame (61) may be provided with a support panel (613) that divides the communication space (612) into an open surface and a closed surface. The closed surface refers to an area of ​​the communication space (612) where the support panel (613) is positioned, and the open surface may be defined as an area of ​​the communication space (612) where the support panel (613) is not positioned. Since the communication space (612) is provided to communicate with the mounting space (15), the mounting space (15) can also be viewed as being divided into an open surface and a closed surface by the support panel (613).

[0203] The interior of the above support frame (61) can be divided into a front space (6a) where the frame panel (62) is positioned and a rear space (6b) where the second rear panel (64) is positioned. The support panel (613) can be fixed to the lower frame (611) and positioned in the rear space (6b).

[0204] Meanwhile, the support panel (613) may be fixed to the lower frame (611) and provided along the width direction (Y-axis direction) of the garment treatment device or the length direction (X-axis direction) of the garment treatment device. FIG. 9 illustrates an example in which the support panel (613) is provided along the width direction of the garment treatment device.

[0205] The above support panel (613) may be provided to include a support body (614) that supports a part of the configuration of the euro section (7, 8) or a part of the configuration of the heat exchange section (9), and a fixing body (615) that fixes the support body (614) to the lower frame (611).

[0206] The above support body (614) may be provided to be positioned at a lower point than the lower frame (611). That is, the lowermost end of the support body (614) may be provided to be positioned at a lower point than the bottom surface (communication space, the lowermost end of the lower frame) of the support frame (61). When the second cabinet (6) is mounted on the first cabinet (1), the bottom edge of the support frame (61) will be supported by the panels (11, 12, 13) of the first cabinet forming the mounting space (15), and the support body (614) will be positioned inside the first cabinet (1). That is, when the second cabinet (6) is fixed on the first cabinet (1), the support body (614) will be positioned at a lower point than the upper end of the first side panel (12).

[0207] Since the above support panel (613) is provided to support the above-mentioned euro section (7, 8) or heat exchange section (9), if the above-mentioned support body (614) is provided to be positioned at a lower point than the above-mentioned lower frame (611), the effect of reducing the height of the entire garment treatment device (100) can be expected.

[0208] The above frame panel (62) may be provided with a first panel through hole (621), a second panel through hole (622), and a third panel through hole (623) that connect the inside of the second cabinet (6) with the outside.

[0209] The above panel first through-hole (621) may be provided to be opened and closed by a panel first door (624) rotatably fixed to the frame panel (62), and the above panel second through-hole (622) may be provided to be opened and closed by a panel second door (filter door, 626) rotatably fixed to the frame panel (62).

[0210] The first door (624) of the panel may be provided with a space for mounting a second control unit (63) that controls the second processing device (100b). In this case, the first through-hole (621) of the panel may be a control unit outlet that exposes the second control unit (63) to the outside of the second cabinet (6).

[0211] The above-mentioned euro section (7, 8) may be equipped with a filter for filtering air discharged from the tub body (30), and the second panel through-hole (622) may be a filter outlet for drawing the filter out to the outside of the second cabinet (6).

[0212] The above panel third penetration hole (623) can be a means (panel air inlet) for supplying air from outside the second cabinet (6) to the euro section (7, 8).

[0213] As shown in Fig. 8, the euro portion may be provided to include a first euro portion (7) that is connected to the tub body (30) to form an air circulation path, and a second euro portion (8) that forms an outside air movement path.

[0214] Figure 10 shows the structure of the urea section (7,8) of the second processing device (100b).

[0215] Figure 11 shows an exploded view of the above-mentioned euro section (7, 8).

[0216] The above first flow path (7) can form a flow path through which air contained inside the tub (3a) can flow in, move outside the tub (3a), and flow back into the tub (3a).

[0217] The first flow path (7) may be provided to include an exhaust flow path (71) connected to the tub exhaust part (25), an air supply flow path (72) connected to the tub air supply part (24), a heat exchange flow path (73) connected to the exhaust flow path, and a blower flow path (74) equipped with a fan for moving air and connecting the heat exchange flow path (73) and the air supply flow path (72).

[0218] The above exhaust path (71) may be provided as an exhaust duct (711) that is detachably fixed to the tub exhaust section (25) of the first treatment device.

[0219] A clothing treatment device characterized in that the exhaust duct (711) includes a first exhaust duct (711a) detachably provided in the tub (3a) and a second exhaust duct (711b) having one end connected to the first exhaust duct (711a) and the other end connected to the filter duct (73a).

[0220] The second exhaust duct (711b) is positioned in front of the first exhaust duct (711a) to receive air from the tub (3a), and the front surface of the second exhaust duct (711b) may be provided as an inclined surface with the upper end positioned further forward than the lower end.

[0221] In order to reduce the vibration of the above tub body (30) from being transmitted to the heat exchange path (73), an exhaust path corrugation (712) may be provided in at least a portion of the exhaust duct (711).

[0222] The above-mentioned air supply path (72) may be provided with an air supply duct (721) that is fixed to the air blower path (74) and provides a path for air to travel through the air blower path. In order to reduce the vibration of the tub body (30) from being transmitted to the air supply duct (721), an air supply path fold (722) may be provided in at least a portion of the air supply duct (721) or at one end of the air supply duct (721).

[0223] The above heat exchange path (73) may be provided with a heat exchange duct (73b) fixed to the support panel (613). The heat exchange duct (73b) may be provided to include a first heat exchange duct (734) in which a first heat exchanger provided in the heat exchange unit (9) is mounted, a second heat exchange duct (735) in which a second heat exchanger provided in the heat exchange unit (9) is mounted, and a connecting duct (736) connecting the heat exchange ducts (734, 735).

[0224] The above heat exchange duct (73b) may be fixed to the bottom surface (support body, 614) of the support panel (613), or may be fixed to a duct mounting portion (616) provided on the support panel (613). The duct mounting portion (616) is a means for protruding from the support body (614) toward the heat exchange duct (73b) to maintain a gap between the bottom surface of the heat exchange duct (73b) and the support body (614).

[0225] Since the air that flows into the first heat exchange duct (73b) from the tub body (30) through the exhaust duct (711) is condensed while passing through the first heat exchanger, condensate may remain inside the heat exchange duct (73b). In order to discharge the condensate remaining inside the heat exchange duct (73b), the second treatment device (100b) may be provided with a condensate discharge unit (75). The condensate discharge unit (75) may be provided in a space formed between the bottom surface of the heat exchange duct (73b) and the support body (614) by the duct mounting unit (616).

[0226] The above heat exchange duct (73b) may be provided to be directly connected to the exhaust duct (711), or may be provided to be connected to the exhaust duct (711) through a filter duct (73a).

[0227] The above filter duct (73a) may include an inlet (732) provided on the bottom surface of the filter duct (73a) to receive air from the exhaust path (71), a duct filter (77) that filters the air introduced from the inlet (732), and an outlet (733) provided on the rear surface of the filter duct (73a) to discharge the air filtered through the duct filter (77) to the heat exchange unit (9).

[0228] The front surface of the above filter duct (73a) is provided as an open surface communicating with the inside, and the open surface can be provided as the filter outlet (731).

[0229] In one embodiment of the present invention, a filter outlet (open surface, 731) communicating with the second panel penetration hole (622) may be provided on one side of the filter duct (73a), and an inlet (732) connected to the exhaust duct (711) may be provided on the other side of the filter duct (73a). The filter outlet (731) is provided on the front surface (the surface facing the frame panel) of the filter duct (73a), and the inlet (732) is provided on the bottom surface of the filter duct (73a) as an example.

[0230] The above filter duct (73a) is a space where a duct filter (77) that filters the air supplied to the exhaust duct (711) is installed.

[0231] As described above, the air flowing through the filter duct (73a) is introduced through the inlet (732) provided on the bottom surface and discharged through the outlet (733) provided on the rear surface, so that the duct filter (77) is arranged to have an incline with respect to the filter duct (73a), so that the contact surface with the flowing air can be increased.

[0232] The above-mentioned airflow path (74) may be provided to include a blower duct (74a) that is fixed to the support panel (613) and connects the heat exchange duct (73b) and the air supply duct (721), and a blower fan (first flow fan, 74b) that moves air along the first flow path (7).

[0233] As shown in Fig. 12, the second flow path (8) may be provided to include a first outside air duct (82) provided inside the second cabinet (6) and through which outside air is introduced, a second outside air duct (83) connected to the first outside air duct (82) and equipped with a third heat exchanger (93) provided in the heat exchange section (9), and a second flow fan (84) for moving air.

[0234] The first outdoor air duct (83) may be provided as a flow path extending along the longitudinal direction (X-axis direction) of the second cabinet, and the second outdoor air duct (83) may be provided as a flow path extending along the height direction (Z-axis direction) of the second cabinet. A duct penetration hole (831) for discharging air to the second flow fan (84) may be provided on one surface of the second outdoor air duct (83).

[0235] The second euro fan (84) may be provided to include a second fan housing (841) that is fixed to the second outdoor air duct (83) to close the duct penetration hole (831) and has a second impeller (846), a housing inlet (842) that is connected to the duct penetration hole (831) to introduce air into the second fan housing (841), a housing outlet (843) that discharges air inside the second fan housing (841) into the second cabinet (6), and a second fan motor (845) that is fixed to the second fan housing (841) to rotate the second impeller (846).

[0236] When the second impeller (846) rotates by the second fan motor (845), outside air is introduced into the second fan housing (841) through the first outside air duct (82) and the second outside air duct (83), and the air inside the second fan housing (841) can be discharged into the second cabinet (6) through the housing exhaust port (843). Meanwhile, the air discharged into the second cabinet (6) can be discharged to the outside of the second cabinet (6) through the panel exhaust port (641) provided in the second rear panel (64).

[0237] As illustrated in Fig. 13, one side of the first external air duct (82) can be fixed to the frame panel (62), and the other side of the first external air duct (82) can be fixed to the fixed frame (619).

[0238] As illustrated in Fig. 12, the first outside air duct (82) may be provided to receive outside air through at least one of a first introduction hole (821) and a second introduction hole (822). The first introduction hole (821) may be provided to be connected to the panel supply hole (623) provided in the frame panel (62), and the second introduction hole (822) may be provided to be connected to the second outlet (636) of the fixing part (631) provided in the board fixing part.

[0239] The first inlet (821) and the second inlet (822) may be provided to supply air from outside the second cabinet (6) through an outside air supply port (81) provided in the second front panel (67). FIG. 13 illustrates an example in which the outside air supply port (81) is provided on the upper surface of the second front panel (67), but the outside air supply port (81) may also be provided on the side surface of the second front panel (67) or the lower surface of the second front panel (67).

[0240] The above heat exchange unit (9) may be provided to include the first heat exchanger (91) provided in the first heat exchange duct (737) to remove moisture from air, the second heat exchanger (92) provided in the second heat exchange duct (738) to heat air, the third heat exchanger (93) provided in the second flow path (8) to exchange heat with outside air, a refrigerant pipe (96) forming a circulation path of refrigerant passing through the heat exchangers (91, 92, 93), and a compressor (94) to move the refrigerant along the refrigerant pipe.

[0241] As shown in Fig. 12, the refrigerant pipe (96) may be provided with a control valve (97) for controlling the pressure of the refrigerant, and a switching unit (95) for controlling the movement path of the refrigerant discharged from the second heat exchanger (92).

[0242] The above refrigerant pipe (96) may be provided to include a first refrigerant passage (961) that guides the refrigerant discharged from the compressor (94) to the second heat exchanger (92), a second refrigerant passage (962) that guides the refrigerant that has passed through the second heat exchanger (92) (refrigerant that has completed heat exchange with air in the second heat exchanger) to the switching unit (95), a third refrigerant passage (963) and a fourth refrigerant passage (964) that connect the switching unit (95) and the third heat exchanger (93), a fifth refrigerant passage (965) that connects the switching unit (95) and the first heat exchanger (91), and a sixth refrigerant passage (966) that guides the refrigerant that has passed through the first heat exchanger (91) to the compressor (94). In this case, the control valve (97) may be provided in the third refrigerant passage (963) and positioned between the switching unit (95) and the third heat exchanger (93).

[0243] The above switching unit (95) can supply the refrigerant supplied through the second refrigerant path (962) to the third refrigerant path (963) or to the fourth refrigerant path (964).

[0244] When the above switching unit (95) supplies refrigerant to the third refrigerant passage (963), the refrigerant passes through the control valve (97) and is then supplied to the third heat exchanger (93). The refrigerant that has passed through the third heat exchanger (93) will be recovered to the switching unit (95) through the fourth refrigerant passage (964) and then supplied to the first heat exchanger (91) through the fifth refrigerant passage (965). In this case, the third heat exchanger (93) will perform the same function (heat absorption function) as the first heat exchanger (91).

[0245] Meanwhile, when the switching unit (95) supplies refrigerant to the fourth refrigerant path (964), the refrigerant is supplied to the third heat exchanger (93). The refrigerant that has passed through the third heat exchanger (93) will be recovered to the switching unit (95) through the third refrigerant path (964) and the control valve (97) and then supplied to the first heat exchanger (91) through the fifth refrigerant path (965). In this case, the third heat exchanger (93) will perform the same function (heat generation function) as the second heat exchanger (92).

[0246] Fig. 14 shows a side cross-sectional view of the filter duct (73a) and the exhaust path (71) and the remaining first path (7).

[0247] As the amount of clothing fed into the drum (3b) increases, the amount of fluid that must flow through the first flow path (7) increases, and the volume of the heat exchanger (9) may also increase.

[0248] Accordingly, the first flow path (7) is provided in a shape that allows air to flow in one direction in the second cabinet (6) and then re-transmits it in the other direction, thereby increasing the length of the first flow path section (7) to accommodate a larger volume of the heat exchange section (9).

[0249] When the above tub air supply unit (35a) is provided at the center side in the width direction of the tub (3a), the drying efficiency of the tub (3a) can be maximized. Accordingly, the air supply duct (721) must be arranged at the center side in the width direction of the second cabinet (6), so that the heat exchange path (73) is arranged to be biased toward one side in the width direction of the second cabinet (6), thereby securing a volume that can accommodate the heat exchange unit (9) and improving the drying efficiency.

[0250] The above filter duct (73a) can be placed on one side in the front-rear direction of the second cabinet (6).

[0251] In one embodiment of the present invention, the filter duct (73a) is arranged on the upstream side of the first flow path (7), and the tub air supply part (35a) is arranged in front of the tub (3a), so that the filter duct (73a) can be arranged on the front side of the second cabinet (6). Accordingly, air moved from the front to the rear along the heat exchange flow path (73) is transported from the rear to the front again along the blower flow path (74) and the air supply flow path (72) and is discharged to the tub (3a), so that a sufficient volume can be secured to accommodate the heat exchange part (9).

[0252] Since the above tub supply port (35a) is positioned at the front, the above tub exhaust part (35b) can be positioned relatively further rearward than the above tub supply port (35a).

[0253] The first exhaust duct (711a) can transport the air discharged through the above tub exhaust section (35b) from the rear to the front, and the second exhaust duct (711b) can move the air from the bottom to the top.

[0254] The flow of air transferred to the second exhaust duct (711b) is directed forward, and the flow of air discharged is directed upward. Therefore, the front surface of the second exhaust duct (711b) may be provided as an inclined surface with the upper end positioned further forward than the lower end. Accordingly, the resistance due to the change in the flow direction of the air flowing in the second exhaust duct (711b) can be minimized.

[0255] The front surface of the above filter duct (73a) is provided as an open surface that is entirely open to form the filter outlet (731).

[0256] The bottom surface of the above filter duct (73a) may include a first area (A1) that is connected to the front surface of the above filter duct (73a) and is provided with the inlet (732), and a second area (A2) that is arranged at the rear of the first area (A1) and forms the remainder of the bottom surface of the above filter duct (73a).

[0257] The above filter duct (73a) may include a filter fixing member (736) fixed to the filter duct (73a) to connect the duct filter (77) to the filter duct (73a).

[0258] The above duct filter (77) can be detachably mounted on the filter duct (73a). For example, a coupling magnet (776) coupled to a magnetic body is accommodated in the duct filter (77), and at least a portion of the filter duct (73a) is provided with a magnetic body, so that the duct filter (77) can be detachably mounted on the filter duct (73a).

[0259] The second door (filter door, 626) may be rotatably provided on the frame panel (62) to open and close the filter outlet (731).

[0260] Accordingly, the user can rotate the second front panel (67) so that the frame panel (62) is exposed to the front, open the filter door (626), and withdraw and insert the duct filter (77) through the filter outlet (731).

[0261] The above duct filter (77) includes one side through which air is introduced and the other side through which air is discharged, and the other side can be detachably provided on the filter duct (73a).

[0262] In one embodiment of the present invention, the other side of the duct filter (77) may be provided to be detachably attached to the filter fixing member (736). Since air flows from one side of the duct filter (77) to the other side, the duct filter (77) is subjected to an external force applied to the other side by hydraulic pressure, and thus, when the other side is fixed to the filter fixing member (736), detachment of the duct filter (77) can be prevented.

[0263] In Fig. 15, the filter duct (73a) and the exhaust duct (711) are illustrated.

[0264] The duct filter (77) provided in the above filter duct (73a) may be provided in the filter duct (73a) in an inclined shape to relatively increase the contact surface with air.

[0265] The above-mentioned filter duct (73a) may be equipped with the above-mentioned duct filter (77), and the above-mentioned duct filter (77) may be equipped with an incline so that the upper end is positioned forward of the lower end within the above-mentioned filter duct (73a). Accordingly, the air delivered to the above-mentioned filter duct (73a) moves from the upper end to the rear end, so that the air is delivered in a direction close to perpendicular to the hydraulic pressure, and the area in contact with the air is maximized, so that the filtering power can be increased.

[0266] The above duct filter (77) may include a first filter (77a) and a second filter (77b) that receives and refilters air filtered by the first filter (77a).

[0267] One end of the second filter (77b) can be fixed to the bottom surface of the filter duct (73a).

[0268] The second filter (77b) may be provided at a different incline from the first filter (77a) based on the bottom surface of the filter duct (73a).

[0269] The second filter (77b) may be provided to have a greater slope with respect to the bottom surface of the filter duct (73a) than the first filter (77a).

[0270] The air filtered through the first filter (77a) can have its hydraulic pressure flowing upward reduced compared to the air filtered through the second filter (77b).

[0271] Accordingly, the direction of movement of air passing through the first filter (77a) will be more parallel to the rear surface of the filter duct (73a), so that the slope of the bottom surface of the filter duct (73a) is provided to be greater than that of the first filter (77a), so that air is delivered in a direction close to perpendicular to the hydraulic pressure, thereby ensuring the reliability of filtration.

[0272] The first filter (77a) and the second filter (77b) may be provided to be mutually compatible.

[0273] The above filter duct (73a) may include a mounting detection unit (734) that detects whether the duct filter (77) is attached.

[0274] The above-mentioned mounting detection unit (734) may be provided in multiple units to detect the first filter (77a) and the second filter (77b), respectively.

[0275] The first filter (77a) and the second filter (77b) may be provided to be interconnected. In this case, the mounting detection unit (734) may be provided to detect whether only one of the first filter (77a) and the second filter (77b) is mounted.

[0276] The end portion of the second exhaust duct (711b) connected to the filter duct (73a) is provided with the same size as the inlet port (732), and the end portion can constitute the first area (A1) of the filter duct (73a).

[0277] The above filter duct (73a) may be equipped with a pressure sensor (735) that detects clogging of the duct filter (77) through the pressure downstream of the duct filter (77). If the pressure value detected by the pressure sensor (735) is below a reference value, clogging of the duct filter (77) may be detected.

[0278] The above pressure sensor (735) is equipped as a differential pressure sensor and detects the difference in pressure between the upstream and downstream of the duct filter (77), and if it is above a reference value, clogging of the duct filter (77) can be detected.

[0279] The first filter (77a) may include a first-first stage (771) fixed to the bottom surface of the filter duct (73a) and a first-second stage (772) extending from the first-first stage (771) and having at least a portion disposed on the front surface of the filter duct (73a).

[0280] The front surface of the above filter duct (73a) is provided with the filter outlet (731) which is an open surface, so that when the filter door (626) is opened, the first-second (772) is exposed forward, so that the first filter (77a) can be easily removed to the outside for cleaning and repair.

[0281] Accordingly, the first and second stages (772) may be provided with a handle (783) that can be gripped for the convenience of the user in withdrawing and inserting the first filter (77a).

[0282] Fig. 16 shows an example of the filter duct (73a) equipped with the first filter (77a) and the second filter (77b).

[0283] As described above, the first filter (77a) includes a first-first stage (771) fixed to the bottom surface of the filter duct (73a) and a first-second stage (772) extending from the first-first stage (771) and at least a portion of which is disposed on the front surface of the filter duct (73a), so that the first-second stage (772) is exposed forward, so that the first filter (77a) can be easily pulled out to the outside for cleaning and repair.

[0284] The second filter (77b) may include a 2-1 stage (773) fixed to the filter duct (73a) and a 2-2 stage (774) positioned above the 1-2 stage (772) of the first filter (77a) and at least a portion of which is positioned on the front surface of the filter duct (73a). Accordingly, the 2-2 stage (774) may also be easily introduced into and withdrawn from the filter duct (73a) through the filter outlet (626).

[0285] As the amount of clothes processed by the above-mentioned clothes processing device (100) increases, the replacement cycle of the filter due to foreign substances and lint may increase. Therefore, the number of duct filters (77) may be provided in multiples, and accessibility may be improved by ensuring that at least one end is exposed through the filter outlet (731).

[0286] Since the air filtered through the first filter (77a) has a hydraulic pressure that flows upward attenuated compared to the air filtered through the second filter (77b), the second filter (77b) may be provided to have a greater incline with respect to the bottom surface of the filter duct (73a) than the first filter (77a).

[0287] The second-second stage (774) of the second filter (77b) may be provided at the upper end of the filter outlet (731). Accordingly, an additional duct filter (77) may be easily accommodated between the first filter (77a) and the second filter (77b).

[0288] The second-first stage (773) of the second filter (77b) may be fixed to the bottom surface of the filter duct (73a), and the second-first stage (773) may be positioned further back than the first-first stage (771).

[0289] In the case where the second-first stage (773) of the second filter (77b) is positioned rearward of the first-first stage (771) of the first filter (77a) on the bottom surface of the filter duct (73a), interference between the first filter (77a) and the second filter (77b) can be eliminated, facilitating installation, etc. In addition, since the filtration area of ​​the second filter (77b) is expanded, the replacement cycle of the second filter (77b) can be extended and the filtration efficiency can be increased.

[0290] The second-first stage (773) of the second filter (77b) may be positioned identical to or behind the first-first stage (771) of the first filter (77a). In this case, when the second-second stage (774) of the second filter (77b) is provided at the upper end of the filter outlet (731), the area in contact with the air passing through the filter duct (73a) can be maximized.

[0291] The second-first stage (773) of the second filter (77b) can be fixed to the upper portion of the first-first stage (771) of the first filter (77a).

[0292] The 1-1 stage (771) of the first filter (77a) can be fixed to the rear end of the second region, and in this case, when the 2-1 stage (773) of the second filter (77b) is fixed to the upper part of the 1-1 stage (771) of the first filter (77a), the duct filter (77) crosses the cross-section of the air flowing through the filtration duct (73a) relatively largely, so that the filtration efficiency can be increased.

[0293] The first-first stage (771) of the first filter (77a) and the second-first stage (773) of the second filter (77b) may be provided to be connected to each other. Therefore, when the first filter (77a) is separated from the filter duct (73a), the second filter (77b) may also be separated from the filter duct (73a). In this case, the mounting detection unit (734) may be provided to detect whether the second-second stage (774) of the second filter (77b) is attached. Therefore, when the first filter (77a) and the second filter (77b) are attached or detached to the filter duct (73a), it is possible to detect whether the duct filter (77) is completely attached or detached only by detecting whether the second-second stage (774), which reacts last, is attached or detached.

[0294] The first-second stage (772) and the second-second stage (774) exposed through the filter outlet (731) are provided with a handle (783) that can be gripped by a user, so that the accessibility of the duct filter (77) for withdrawal and introduction can be improved.

[0295] Fig. 17 shows an example of the filter duct (73a) equipped with the first filter (77a) and the second filter (77b).

[0296] The first filter (77a) includes a first-first stage (771) fixed to the bottom surface of the filter duct (73a) and a first-second stage (772) extending from the first-first stage (771) and having at least a portion disposed on the front surface of the filter duct (73a), and the first-second stage (772) may be provided at the upper end of the filter outlet (731).

[0297] The first-first stage (771) of the first filter (77a) may be fixed to the rear end of the second area (A2). Since the amount of foreign substances filtered by the first filter (77a) is the greatest, when the first-second stage (771), which is the upper end of the first filter (77a), is fixed to the upper front end of the filter duct (73a), and the first-first stage (771), which is the lower end of the first filter (77a), is fixed to the rear end of the bottom surface of the filter duct (73a), the cross-sectional area of ​​the air in contact with the first filter (77a) is maximized, so that the filtration efficiency can be increased.

[0298] The above second filter (77b) may include a 2-1 stage (773) fixed to the bottom surface of the filter duct (73a) and a 2-2 stage (774) fixed to the upper surface of the filter duct (73a).

[0299] The above 2-2 stage (774) may be positioned in front of the 2-1 stage (773). Therefore, when the first filter (77a) is pulled out through the filter outlet (731), the 2-2 stage (774) may be exposed. Therefore, the user may pull the second filter (77b) out of the filtration duct (73a) through the 2-2 stage (774) or the handle (783) provided on the 2-2 stage (774).

[0300] The second-first stage (773) of the second filter (77b) may be located at the same position as or behind the first-first stage (771) of the first filter (77a).

[0301] The second-first stage (773) of the second filter (77b) can be fixed to the upper portion of the first-first stage (771) of the first filter (77a).

[0302] Fig. 18(a) illustrates one embodiment of the filter duct (73a) equipped with the first filter (77a) and the second filter (77b).

[0303] The first-first stage (771) of the first filter (77a) may be fixed to the bottom surface of the filter duct (73a), and the first-second stage (772) may be fixed to the upper portion of the front surface of the filter duct (73a).

[0304] The second-first stage (773) of the second filter (77b) is arranged to overlap the upper portion of the first-first stage (771) or the first-first stage (771), and the second-second stage (774) can be fixed to the upper portion of the rear surface of the filter duct (73a).

[0305] At this time, the first-first stage (771) of the first filter (77a) and the second-first stage (773) of the second filter (77b) can be placed at the front end of the second area (A2).

[0306] Fig. 18(b) illustrates one embodiment of the filter duct (73a) equipped with the first filter (77a) and the second filter (77b).

[0307] The first-first stage (771) of the first filter (77a) may be fixed to the bottom surface of the filter duct (73a), and the first-second stage (772) may be fixed to the lower part of the front surface of the filter duct (73a).

[0308] That is, the first filter (77a) may be provided in a shape that shields the inlet (732). The first-first stage (771) may be fixed to the front end of the second area (A2), and the first-second stage (772) may be fixed to the front end of the first area (A1), so that the size of the first filter (77a) may correspond to the inlet (732).

[0309] The second-first stage (773) of the second filter (77b) is arranged to overlap the upper portion of the first-first stage (771) or the first-first stage (771), and the second-second stage (774) can be fixed to the upper portion of the front surface of the filter duct (73a).

[0310] Accordingly, since both the first-second stage (772) and the second-second stage (774) are exposed through the filter outlet (731), replacement and cleaning of the duct filter (77) can be facilitated.

[0311] Figure 19 shows an example of the filter fixing unit (736).

[0312] The above second region (A2) and the filter fixing portion (736) can be formed integrally.

[0313] The above filter fixing part (736) may be provided including a first filter fixing part (736a) that fixes the first filter (77a) and a second filter fixing part (736b) that fixes the second filter (77b).

[0314] The above filter fixing part (736) may be provided with side ribs (7361) fixed to both sides of the filter duct (73a) and a rear rib (7362) connecting the rear ends of the two side ribs (7361). That is, the filter fixing part (736) may be provided so as not to cross the front surface of the filter (73a).

[0315] Since the above side rib (7361) is fixed to the side of the filter duct (73a), unfiltered air can be prevented from leaking between the side of the filter duct (73a) and the side rib (7361).

[0316] Accordingly, the front end of the duct filter (77) placed on the front of the filter duct (73a) can be easily inserted and removed by the user by pushing or pulling.

[0317] The above duct filter (77) includes one side through which air is introduced and the other side through which air is discharged, and the other side can be detachably provided on the filter duct (73a).

[0318] In one embodiment of the present invention, the other side of the duct filter (77) may be provided to be detachably attached to the filter fixing member (736). Since air flows from one side of the duct filter (77) to the other side, the duct filter (77) is subjected to an external force applied to the other side by hydraulic pressure, and thus, when the other side is fixed to the filter fixing member (736), detachment of the duct filter (77) can be prevented.

[0319] The above back rib (7362) can be fixed to the bottom surface of the above filter duct (73a). Accordingly, unfiltered air can be prevented from being discharged through the gap between the back rib (7362) and the second area (A2).

[0320] The back rib (7362) of the second filter fixing part (736b) may be fixed to the upper portion of the back rib (7362) of the first filter fixing part (736a). Each of the back ribs (7362) is provided so as not to be spaced apart from each other, so that unfiltered air can be prevented from being discharged between the two back ribs (7362).

[0321] Fig. 20 illustrates one embodiment of the duct filter (77).

[0322] At least one of the first filter (77a) and the second filter (77b) may be provided in the following form. The first filter (77a) and the second filter (77b) may be provided to be compatible with each other, and the compatible duct filter (77) may be provided as follows.

[0323] The above duct filter (77) may be provided to include a frame portion (770) formed along the inner surface of the filter duct (73a), a filter net (775) whose edge is fixed by the frame portion (770) to filter air, and a shape-maintaining portion (778) inserted between the frame portions (770) to maintain the shape of the frame (770).

[0324] The above frame portion (770) may include a second frame (79) fixed to the filter duct (73a), and a first frame (78) coupled to the second frame (79) and exposed toward the outside of the filter duct (73a).

[0325] The above shape-maintaining part (778) may be provided to be interposed between the second frame (6) and the first frame (78).

[0326] The above shape-maintaining portion (778) may be provided with a material having higher rigidity than at least one of the second frame (79) and the first frame (78) to prevent deformation of the frame portion (770).

[0327] The above-mentioned strainer (775) can provide tension to the inside of the frame portion (770) by resisting the tensile force that pulls the edge by the frame portion (770). Therefore, a torsional moment may occur in the frame portion (770) due to the tension of the strainer (775). The shape-maintaining portion (778) is provided with a material having a torsional rigidity greater than or equal to that which can resist the torsional moment that occurs in the frame portion (770), thereby preventing the frame portion (770) from torsion.

[0328] Fig. 21 illustrates a schematic diagram of the manufacturing process of the frame portion (770), and Fig. 22 illustrates a flow chart of the manufacturing process of the frame portion (770). The manufacturing process of the frame portion (770) will be described below with reference to Figs. 21 and 22.

[0329] The above frame part (770) can be manufactured by a manufacturing method including an extrusion step (S1) of heating the material forming the frame part (770) to a high temperature and continuously extruding a product of a certain cross-section, a cutting step (S2) of cutting the material that has undergone the extrusion step (S1) to fit the length of each side of the duct filter (77), and a fusing step (S3) of heating and thermally fusing the ends of the material that has undergone the cutting step (S2) to correspond to the shape of the opening (350).

[0330] Accordingly, since the frame portion (770) in the form of a closed curve extending along the perimeter of the inner surface of the filter duct (73a) is not produced integrally by injection molding or the like, the initial mold manufacturing cost is reduced and the range of material selection for the frame portion (770) is expanded.

[0331] In addition, since it is processed only with compressive and shear stresses, the degree of freedom of shape can be improved when a cross-section for fixing the shape-maintaining portion (778) or / and the filter net (775) is formed inside the frame portion (770).

[0332] A fusion line (L1) may be formed in the above frame portion (770) by fusing the ends of each material. The fusion line (L1) may not be clearly visually distinguishable.

[0333] The above fusion line (L1) can be confirmed to use a polymer different from the material constituting the frame portion (770) during the fusion process.

[0334] The above fusion line (L1) is sufficient if the end of the material that has gone through the extrusion step (S1) and the cutting step (S2) is deformed by physical force such as heat and is physically and chemically distinct from other parts in shape, structure, and properties. The above fusion line (L1) is sufficient if a person skilled in the art can recognize the characteristics generated by fusion.

[0335] The second frame (79) and the first frame (78) can be manufactured with different cross sections or materials.

[0336] Fig. 21(a) shows a method for manufacturing the first frame (78), and Fig. 21(b) shows a method for manufacturing the second frame (79).

[0337] The above first frame (78) can be manufactured by a manufacturing method including a first frame extrusion step (S1a), a first frame cutting step (S2a) of cutting the material that has undergone the first frame extrusion step (S1a), and a first frame fusing step (S3a) of heating and thermally fusing the end of the material.

[0338] In the first frame (78), the first frame fusion line (L11) can be formed by the first frame fusion step (S3a).

[0339] A coupling magnet (776) that generates magnetic force is accommodated inside the second frame (79), and at least a portion of the filter duct (73a) is provided with a magnetic material that can be coupled with the coupling magnet (776), so that the second frame (79) can be detachably fixed to the filter duct (73a).

[0340] Since the above second frame (79) can accommodate the above-mentioned coupling magnet (776), it can be manufactured as follows.

[0341] The above second frame (79) can be manufactured by a manufacturing method including a second frame extrusion step (S1b), a second frame cutting step (S2b) of cutting the material that has gone through the second frame extrusion step (S1b), an insertion step (S25) of accommodating the coupling magnet (776) in the cut material, and a second frame fusing step (S3b) of heating and thermally fusing the end of the material in which the coupling magnet (776) is accommodated.

[0342] That is, in the case of an attachment target such as the second frame (79), the coupling magnet (776) must be accommodated, so an insertion step (S25) in which the coupling magnet (776) is accommodated may be further included after the cutting step (S2).

[0343] In order to prevent detachment of the above-mentioned coupling magnet (776) and ensure attachment reliability, it is preferable that the above-mentioned coupling magnet (776) be inserted into a coupling magnet receiving groove (7913) that is separately formed inside the second frame (79), which will be described later. Therefore, the insertion step (S25) can be performed after the cutting step (S2) and before the fusion step (S3).

[0344] In the second frame (79), the second frame fusion line (L12) can be formed by the second frame fusion step (S3b).

[0345] Fig. 23 illustrates an example of a cross-section (hereinafter, “cross-section”) in a direction perpendicular to the extrusion direction of the first frame (78), and Fig. 24 illustrates an example of a cross-section (hereinafter, “cross-section”) in a direction perpendicular to the extrusion direction of the second frame (79). Hereinafter, the characteristics of the cross-section of the first frame (78) and the cross-section of the second frame (79) will be described.

[0346] The second frame (79) and the first frame (78) are formed on a contact surface where they face each other in combination, and a recessed portion (781, 791) protruding or recessed from the contact surface is formed, and the second frame (79) and the first frame (78) can be mutually combined by fitting the recessed portions (781, 791).

[0347] At least one of the second frame (79) and the first frame (78) may be provided with a shape-maintaining part receiving groove (784, 794) in which the shape-maintaining part (778) is received.

[0348] The edge of the above-mentioned filter net (775) can be fixed to the frame part (770) by the pressure generated by the combination of the grooved part (781, 791) and the shape-maintaining part (778) and the frame part (770).

[0349] The above-mentioned groove portion may be provided with a first groove portion (791) that is formed to protrude on one side of the second frame (79) facing the first frame (78) and a second groove portion (781) that is formed to be recessed to fit with the first groove portion (791) on one side of the first frame (78) facing the second frame (79).

[0350] As the first groove (791) is provided in a protruding shape, the degree of freedom in the position and shape of the combined magnet receiving groove (792) can increase.

[0351] The second frame (79) can be placed relatively downstream of the air flowing through the filter duct (73a) compared to the first frame (78).

[0352] The above-mentioned strainer (775) can apply an external force to the frame portion (770) in a downstream direction by the flow of air. In this case, if the first groove portion (791) is provided in a protruding shape and the second groove portion (781) is provided in a recessed shape, the force with which the groove portions (51, 61) support the strainer (775) in the upstream direction can be increased. Accordingly, the strainer (775) can be stably fixed to the frame portion (770) without being excessively stretched.

[0353] The above-mentioned grooves (781, 791) may be provided with a plurality of protrusions protruding from the contact surface and a plurality of recessed portions matching the plurality of protrusions. The plurality of protrusions and the plurality of recessed portions may be arranged in a row along a direction transverse to the extrusion (extension) direction of the frame portion (770). The ease of manufacturing the frame portion (770) may be improved.

[0354] Preferably, the plurality of protrusions and the plurality of recesses may be arranged in a row from the inside to the outside of the frame on each side of the frame portion (770). Accordingly, the bonding force is transmitted to the filter net (775) to the greatest extent through the recessed portions (781, 791), so that the filter net (775) can be stably fixed to the frame portion (770).

[0355] The shape-maintaining portion receiving grooves (784, 794) may be formed between the plurality of recessed portions and the plurality of protruding portions. Accordingly, when the shape-maintaining portion (778) is received in the frame portion (770), the grooves (781, 791) are joined in the inner and outer directions of the frame portion (770), so that the shape-maintaining portion (778) is prevented from coming off and can be stably fixed.

[0356] A sealing rib (782) protruding to be exposed to the outside of the filter duct (73a) may be formed around the outer circumference of the first frame (78). When the duct filter (77) is fixed to the opening, the sealing rib (782) may block air from flowing through the joint between the outer circumference of the frame portion (770) and the opening (350).

[0357] The angle at which the sealing rib (782) protrudes from the edge of the frame portion (770) may be greater than the angle formed by the duct filter (77) with the inner surface of the filter duct (73a). Accordingly, the sealing rib (782) and the inner surface of the duct body (310) naturally come into contact and are pressurized, and the flow of air can be effectively blocked.

[0358] At least a portion of the first frame (78) may be formed with a handle (783) that protrudes outward from the filter duct (73a) and can be gripped by a user.

[0359] The user can pull the handle (783) exposed to the outside of the filter duct (73a) toward the outside of the filter duct (73a) to separate the frame portion (770) from the opening portion (350). Since the user does not have to insert a finger into the narrow gap formed between the outer surface of the opening portion (350) and the frame portion (770) to separate the duct filter (77), usability can be improved.

[0360] The bonding force generated by the bonding of the above grooves (781, 791) is set to be greater than the bonding force by which the bonding magnet (776) is attached to the filter duct (73a), so that by pulling the handle (783), not only the first frame (78) but also the second frame (79) can be pulled out at once.

[0361] The protrusion angle and formation position of the above handle (783) may be changed depending on the position where the duct filter (77) is placed. The handle (783) may be provided so that a user of average height can hold it within the range of motion of the arm without lifting the heel or bending the waist.

[0362] The handle (783) may be provided with an anti-slip portion (783a) to improve the user's usability. The anti-slip portion (783a) may be provided with a groove or protrusion that fits the shape of a finger or a shape that prevents friction, and may be formed separately from the frame portion (770) and subsequently attached to the handle (783).

[0363] The above drawing 23(a) is an example of the first frame (78) in which the handle (783) and the sealing rib (782) are formed, and the above drawing 23(b) is an example of the first frame (78) in which the handle (783) and the sealing rib (782) are not formed.

[0364] As illustrated in the above drawing 24, the second frame (79) may be formed with a coupling magnet receiving groove (792) capable of receiving the coupling magnet. The coupling magnet (776) may be formed of an elastic material so that it can be easily received in the coupling magnet receiving groove (792).

[0365] Figure 25 illustrates the grooves (781, 791) provided in the second frame (79) and the first frame (78).

[0366] As one embodiment of the present invention, the second frame (79) is provided with a first groove (791) that is provided as a protrusion protruding from the contact surface, and the first frame (78) is provided with a second groove (781) that is provided as a recessed portion recessed from the contact surface. This is only one embodiment of the present invention, and the protrusion and the recessed portion may be provided interchangeably in the first frame (78) and the second frame (79).

[0367] For convenience of explanation, the protrusion is hereinafter referred to as the first recessed portion (791) and the depression is hereinafter referred to as the second recessed portion (781).

[0368] The first groove (791) may include a first extension (7911) extending from the contact surface, and a second extension (7912) extending from an end of the first extension (7911).

[0369] The shapes of the first extension portion (7911) and the second extension portion (7912) may be different in a cross-section perpendicular to the extension direction of the frame portion (770).

[0370] In a cross-section perpendicular to the direction in which the first recessed portion (791) protrudes, it is preferable that at least a portion of the second extension portion (7912) does not overlap with the first extension portion (7911) based on the direction in which the first recessed portion (791) protrudes. Accordingly, even if an external force is applied in a direction that separates the first recessed portion (791) and the second recessed portion (781) from each other while they are coupled, they can be prevented from being easily separated.

[0371] Fig. 25(a) shows an example (7912a) of the second extension portion (7912) formed in a round shape.

[0372] The above second extension portion (7912) may be provided in a circular shape with a diameter greater than the length of the extended width of the first extension portion (7911).

[0373] Accordingly, at least a portion of the extended cross-section of the second extension portion (7912) is provided to be larger than the extended cross-section of the first extension portion (7911), so that separation of the first frame (78) and the second frame (79) can be prevented.

[0374] FIG. 25(b) shows an example in which the second extension portion (7912) is provided in a hook shape (7912b) on one side from the end of the first extension portion (7911).

[0375] In the case where the second extension part (7912) is provided in a hook shape (7912b) through FIG. 25 below, the direction in which the second extension part (7912) is bent from the first extension part (7911) will be described below.

[0376] The above drawing 25 illustrates a cross-section of line D-D' that crosses the inner and outer sides of the frame portion (770) in the shape of a closed curve. For the convenience of the following description, the direction toward the outer side of the frame portion (770) is referred to as the outer direction (R1), and the direction toward the outer side of the frame portion (770) is referred to as the inner direction (R2).

[0377] FIG. 26(a) illustrates a pair of second extension portions (7912), one of which is bent in the outward direction (R1) from the first extension portion (7911) and the other is bent in the inward direction (R2) from the first extension portion (7911).

[0378] When the second extension portion (7912) is bent from the end of the first extension portion (7911) in a direction facing each other as shown in Fig. 26(a), the edge of the filter net (775) can be prevented from being separated from the frame portion (770).

[0379] For example, when the strainer (775) is pulled in an outward direction (R1) or an inward direction (R2) in which it is separated from the frame portion (770), the bent second extension portion (7912) can be deformed toward the center inward of the frame portion (770) due to the elasticity of the material itself. Accordingly, the force with which the end of the second extension portion (7912) binds the strainer (775) to the center of the frame portion (770) increases, so that the fixing reliability of the strainer (775) can be improved.

[0380] Fig. 26(b) illustrates a pair of second extension portions (7912) bent in the outward direction (R1) from the first extension portion (7911). When the second extension portion (7912) is arranged as shown in Fig. 26(b), it may be advantageous in resisting the tension of the strainer (775).

[0381] For example, when the filter net (775) filters the air inside the drum (3a) and transmits force to the central portion to transmit tension in the inward direction of the frame portion (770), since the second extension portion (412) is arranged in the outward direction (R2), the force resisting buckling deformation is maximized, so that the frame portion (770) can stably support the filter net (775).

[0382] In this case, when the first groove (791) is formed as a protrusion in the second frame (79), the second extension (7912) supports the strainer (775) receiving force toward the downstream side toward the upstream side, so that the reliability of the connection between the strainer (775) and the frame part (770) can be improved.

[0383] Fig. 27 illustrates an example of the frame portion (770). Fig. 27(a) illustrates the second frame (79) as viewed from the front of the filter duct (73a), and Fig. 27(b) illustrates the first frame (78) coupled to the second frame (79).

[0384] The frame portion (770) illustrated in the above drawing 27 is an example of a rectangle in which all of the inner angles are formed at right angles and one pair of opposing sides is formed to be longer than the length of the other pair of sides.

[0385] For convenience of explanation, the length of a pair of relatively long sides is referred to as the long side (D1), and the length of the remaining pair of relatively short sides is referred to as the short side (D2).

[0386] In the second frame (79), the coupling magnet receiving groove (792) is formed in the extrusion step (S1), and the coupling magnet (776) can be received in each side that has undergone the cutting step (S2) to match the length of each side of the opening (350).

[0387] When the ends of each side where the above-mentioned coupling magnets are received are fused, a certain fusion gap (G) may be formed between each end to be fused and the coupling magnets (776) so that the fusion is not hindered by the coupling magnets (776) or the bonding force is not reduced due to the fusion. Accordingly, the fusion gap (G) may be formed so that at least a portion thereof overlaps the fusion line (L1).

[0388] The above fusion gap (G) is formed at each corner of the second frame (79), and the coupling magnet (776) can be interposed in the second frame (79) so as to be discontinuous at the corner.

[0389] When the filter net (775) and the first frame (78) are coupled to the second frame (79) as described above, as shown in Fig. 27(b), the filter net (775) can be pressurized in the direction of air flow while its edge is pulled by the frame portion (770). Accordingly, the frame portion (770) can receive tension in the inward direction (R2).

[0390] When the frame portion (770) receives tension in the inward direction (R2), the central portion of each side, whose rigidity is reinforced by the coupling magnet (776), can resist the tension, but the rigidity is attenuated by the coupling magnet receiving groove (792), and the portion of the fusion gap (G) where the coupling magnet (776) is not received inside cannot resist the tension of the strainer (775) and may be deformed. Accordingly, the frame portion (770) may be deformed to be bent or folded based on the corner where the fusion gap (G) is formed.

[0391] In addition, when a twist occurs in each side due to the tension of the above-mentioned filter (775), the twist angle is proportional to the length of the side, so the twist angle (7701) occurring in the long side (D1) may be greater than the twist angle (7702) occurring in the short side (D2).

[0392] Accordingly, the long side (D1) can be twisted and deformed as if folded based on a pair of opposing corners of the frame portion (770).

[0393] Fig. 28 illustrates an example of the shape-maintaining portion (778). Fig. 28(a) illustrates the shape-maintaining portion (778) as seen from the front of the filter duct (73a), and Fig. 27(b) illustrates a cross-section of F-F' crossing the shape-maintaining portion (778) from the inside to the outside, forming a closed curve.

[0394] The above shape-maintaining part (778) may be provided in a round bar shape extending along the circumference of the duct filter (77).

[0395] The above shape-maintaining portion (778) may be made of a metal material and may include at least one welding line (L2) formed by welding an end portion to form a closed curve.

[0396] The above welding line (L2) may not be clearly distinguishable in appearance. However, it may be physically identified as a protruding, uneven surface due to welding, marks of polishing the uneven surface, marks of discoloration due to heat treatment, or marks of surface treatment.

[0397] Even if the above welding line (L2) is not visible externally, it can be distinguished by a density or thickness that is somewhat uneven or different from other areas. It is sufficient for the above welding line (L2) to be provided so that a person skilled in the art can recognize it as a characteristic resulting from welding.

[0398] The weld joint connecting the shape-maintaining portion (778) to the welding line (L2) may have lower strength than other portions. Therefore, the welding line (L2) is provided at a point that does not overlap with the fusion gap (G) or the fusion line (L1), thereby avoiding deformation concentrated on the fusion gap (G) or the fusion line (L1).

[0399] When the frame portion (770) is formed as a rectangle in which all of the inner angles are formed at right angles and one pair of opposing sides is longer than the length of the other pair of sides, the welding line (L2) may be formed in a portion of the side of the frame portion (770) that is inserted into the short side (D2).

[0400] As described above, when a twist occurs in each side due to the tension of the strainer (775), the twist angle is proportional to the length of the side, and the twist angle (7701) occurring in the long side (D1) is greater than the twist angle (7702) occurring in the short side (D2). Therefore, when the welding line (L2) is formed in the short side (D2), a strong load is not applied to the welding line (L2) which is relatively weak, and thus the reliability of the strength of the shape-maintaining portion (778) can be improved.

[0401] When the above opening (350) is formed in a polygonal shape, the corner portion (779) of the shape-maintaining portion (778) can be formed to have a curved shape with an R radius. Accordingly, when an external force is applied to the shape-maintaining portion (778), the load is concentrated on the corner portion (779), preventing it from breaking.

[0402] The above shape-maintaining member (778) is made of a material having at least a rigidity capable of withstanding the tension of the strainer (775) and a torsional rigidity capable of resisting the torsional moment of the frame member (770) caused by the tension applied by the strainer (775) to the frame member (770), thereby preventing the long side (D1) from being twisted and deformed as if folded based on a pair of opposing corners of the frame member (770) as described above.

[0403] Figure 29 shows the frame portion (770), the filter net (775), and the shape-maintaining portion (778) being assembled.

[0404] The shape-maintaining portion (778) may be inserted into the center of the frame portion (770). That is, the length (t1) from the contact surface (P) of the first frame (78) to the end of the first frame (78) and the length (t2) from the contact surface (P) of the second frame (79) to the end of the second frame (79) may be provided to be the same, and the length from each of the contact surfaces (P) to which the shape-maintaining portion receiving grooves (784, 794) are inserted may be provided to be the same.

[0405] That is, the distance between the shape-maintaining part (778) and the outer side of the first frame (78) and the distance between the shape-maintaining part (778) and the outer side of the second frame (79) can be set to be the same.

[0406] When the frame portion (770) is made of the same material and the shape-maintaining portion (778) extends across the center of each side of the frame portion (770), deformation of the frame portion (770) can be most effectively prevented and production and design can be simplified.

[0407] The duct filter (77) can be formed by an assembly step (S4) in which the filter net (775) is stacked on the first frame (78), the shape-maintaining part (778) is inserted on the filter net (775), and the protrusion (first groove part (791)) of the second frame (79) is fitted into the recessed part (second groove part (781)) of the first frame (78) so that the second frame (79) and the first frame (78) are joined.

[0408] When the first recessed portion (791) in the shape of the protrusion is formed in the second frame (79), and the second recessed portion (781) in the shape of the depression is formed in the first frame (78), the strainer can be interposed and fixed between the first frame (78) and the shape-maintaining portion (778). When an external force in the downstream direction is applied to the strainer (775) due to the flow force of air, the recessed portions (781, 791) of the frame portion (770) and the shape-maintaining portion (778) support the strainer (775) in the upstream direction, so that the strainer (775) is not excessively stretched and can be stably fixed to the frame portion (770).

[0409] Figure 30 shows the duct filter (77) as seen from the front of the opening (350).

[0410] The above filter duct (73a) may be equipped with a magnetic sensor (314) to be described later for detecting the strength of a magnetic field, etc. Accordingly, the frame portion (770) may accommodate a magnetic source (777) whose magnetic signal is detected by the magnetic sensor (314) to detect whether the duct filter (77) is attached to the filter duct (73a).

[0411] The handle (783) and the magnetic field source (777) may be formed or accommodated in at least a portion of the frame portion (770). FIG. 30 illustrates an example in which the magnetic field source (777) is accommodated in the upper center of the frame portion (770) and the handle (783) is formed on the left side of the frame portion (770).

[0412] Based on the above Fig. 30, Figs. 31 to 33 illustrate cross-sections crossing the inner side to the outer side of the frame portion (770). Fig. 31 illustrates a cross-section of A-A' where the handle (783) and the magnetic field source (777) are not formed, Fig. 32 illustrates a cross-section of B-B' where the magnetic field source (777) is accommodated, and Fig. 33 illustrates a cross-section of C-C' where the handle (783) is accommodated. This is merely one embodiment of the present invention, and the handle (783) and the magnetic field source (777) may not be formed or may be formed to overlap.

[0413] The above drawing 30 shows the second frame (79) in which the coupling magnet (776) is received and the first groove (791) is formed to protrude from the contact surface (P), the shape-maintaining part (778) laminated on the second frame (79), the strainer (775) laminated on the shape-maintaining part (778), and the first frame (78) in which the second groove (781) is formed to be sunken from the contact surface (P) laminated on the strainer (775).

[0414] The frame part (770) is joined by the shape of the first groove part (791) and the second groove part (781), and the filter net (775) can be fixed by the pressure of the shape-maintaining part (778) and the frame part (770).

[0415] The above is one embodiment, and the protrusion and depression directions of the first groove portion (791) and the second groove portion (781) can be switched at each contact surface (P), and the filter net (775) can be fixed by the pressure of the shape-maintaining portion (778) and the second frame (79).

[0416] Since the above-mentioned filter net (775) is tightly pressed by the frame part (770) and the shape-maintaining part (778), it can aesthetically convey to the user that the duct filter (77) has a solid strength suitable for commercial use.

[0417] Figure 32 illustrates the magnetic field source (777) being fixed to the second frame (79). The second frame (79) may be provided with a magnetic field source receiving groove (793) in which the magnetic field source (777) can be received.

[0418] The above magnetic field source receiving groove (793) can replace a part of the first groove (791) and protrude from the contact surface (P) to fit into the second groove (781) of the first frame (78).

[0419] Accordingly, even if the second frame (79) is extruded in bulk, the magnetic field source (777) can be accommodated through a process such as cutting only a portion of the first groove (791) as a post-processing, so that the production cost can be reduced.

[0420] Figure 33 shows the handle (783) and the sealing rib (782) formed on the first frame (78).

[0421] As described above, the protrusion angle and formation position of the handle (783) can be changed depending on the position where the duct filter (77) is placed.

[0422] It may be provided so that a user of average height can hold the handle (783) within the range of motion of the arm without lifting the heel or bending the waist.

[0423] For example, when the lower part of the duct filter (77) is close to the ground, the duct filter (77) may be provided on the upper or side of the duct filter (77) in consideration of the user's availability, and a protruding angle may be formed so as to be tilted toward the center of the filtration duct (73a) to prevent collision with the inner surface of the filtration duct (73a) in which the duct filter (77) is accommodated.

[0424] For ease of production, the handle (783) may be formed and attached separately from the first frame (78).

[0425] As described above, the angle at which the sealing rib (782) protrudes from the outer edge of the first frame (78) may be greater than the angle formed by the inner surface of the filter duct (73a) on which the duct filter (77) is mounted. Accordingly, the sealing rib (782) and the inner surface of the duct body (310) naturally come into contact and are pressurized, and the flow of air can be efficiently blocked.

[0426] The above sealing rib (782) may be formed only on a part of the first frame (78), and for ease of production, the sealing rib (782) may be formed and attached separately from the first frame (78).

[0427] The present invention may be implemented in various modified forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
