Description

Technical Field

[0001] The utility model relates to a clothing processing device, and more particularly to a clothing processing device with a filter box for filtering foreign matter in the air. Background Art

[0002] Recently, a laundry treatment device that performs a drying process to remove moisture from laundry has emerged. The existing laundry treatment device dries laundry by supplying hot air to a drum containing laundry, thereby greatly shortening the drying time of the laundry, and can also sterilize and disinfect the laundry.

[0003] Existing clothes treating apparatuses may use an electric heater to provide hot air to the drum. The hot air may be generated by arranging a heater in a duct communicating with the drum to heat the air flowing into the drum.

[0004] Recently, a laundry treatment device that uses a heat pump system to heat the air flowing into the drum has appeared. This laundry treatment device cools the air exhaled from the laundry through an evaporator to condense moisture, and reheats the air through a condenser to generate high-temperature dry hot air.

[0005] The clothes treating apparatus with the heat pump system has the advantages of higher energy efficiency, simpler installation, and easier maintenance and replacement than a clothes treating apparatus using an electric heater.

[0006] However, the existing laundry treatment apparatus has a problem that the air expelled from the laundry directly hits the evaporator, causing foreign matter such as lint to adhere to the evaporator. The foreign matter attached to the evaporator hinders the heat exchange between the cold refrigerant of the evaporator and the air expelled from the drum, thereby reducing the drying efficiency.

[0007] In particular, there is a problem that if foreign matter remaining in the evaporator is decomposed by bacteria or the like, even the laundry contained in the drum may be contaminated.

[0008] In order to prevent this, a clothes treating device equipped with a filter unit has been developed, which can filter foreign matter such as lint or dust that may flow into the evaporator. (See Korean Patent Publication No. 10-2017-0009657)

[0009] In such a clothes treating apparatus, a filter part is detachably mounted on the clothes treating apparatus to filter foreign matters, and a user can remove the collected foreign matters by separating the filter.

[0010] The filter part may have a double filter to filter foreign matter of different sizes, thereby improving the removal performance of the foreign matter. The double filter may filter lint or dust of different sizes.

[0011] For the filtering part of the double filter, the inner filter must be installed after the outer filter is installed. However, due to the carelessness of the user, it is very likely that only the outer filter or the inner filter is installed and the existing laundry processing device is used.

[0012] In particular, since the external filter is formed in a stepped manner at the mounting portion of the inlet so as not to be exposed to the outside, there is often a case where a user only mounts the internal filter on the mounting portion and uses the laundry processing apparatus.

[0013] Thus, there is a problem that the outer filter cannot well filter fine lint and dust having passed through the inner filter, and lint or dust generated from laundry flows again into the inside of the drum accommodating the laundry or accumulates in the heat exchanger itself.

[0014] In order to improve this problem, there is a laundry treatment device that operates the laundry treatment device only when both the external filter and the internal filter are installed. (Korean Patent Publication No. 10-2021-0128702)

[0015] The laundry processing device is provided with a magnet in the filter part, and a detection part such as a Hall effect sensor for detecting the magnet is provided in the mounting part. Thus, the laundry processing device can be operated only when the detection part detects the magnet in the filter part, thereby guiding the user to combine the filter part with the mounting part.

[0016] However, in this laundry processing device, the internal filter and the external filter respectively have magnets, and the detection unit must detect the two magnets at the same time or detect that the two magnets overlap, so there is a problem of difficulty in accurately detecting whether the internal filter and the external filter are installed.

[0017] Therefore, there is a problem that when only the internal filter or only the external filter is installed, if any magnet is configured at the same height as the detection unit, the detection unit mistakenly assumes that the magnets configured on both the internal filter and the external filter are configured and operates the laundry processing device.

[0018] In particular, due to setting tolerance, when the magnet of the internal filter and the magnet of the external filter do not accurately overlap, even if the internal filter and the external filter are both set, the detection unit cannot detect sufficient magnetic force, resulting in a problem of not operating the clothing processing device.

[0019] That is, when a plurality of magnets are used as in the conventional laundry processing apparatus, there is a problem that the reliability of the detection unit cannot be well guaranteed due to the low resolution of the detection unit.

[0020] In addition, the existing clothing processing device also discloses a cantilevered magnet inside the external filter, and the internal filter is configured in a manner of pushing the cantilever away, so that the detection part can detect the installation of two filters by detecting only one magnet.

[0021] However, there is a problem that even if the internal filter is not installed on the external filter, if the cantilever is bent by the weight of the magnet or bent at a certain angle toward the detection part due to temporary vibration, the detection part detects this and mistakenly believes that the internal filter is installed.

[0022] In addition, there is a problem that the cantilever arm hinders the entry and exit of the internal filter or is damaged.

[0023] As a result, the conventional laundry processing apparatus cannot physically detect whether the internal filter and the external filter are installed, but detects whether the internal filter and the external filter are installed by an electrical control method using a detection part and a magnet, so there is a problem that reliability cannot be guaranteed. Utility Model Content

[0024] The problem to be solved by the utility model is to provide a clothes processing device which can recognize whether the external filter and the internal filter are both combined in a physical way.

[0025] The problem to be solved by the utility model is to provide a clothes processing device in which a user can recognize whether an external filter or an internal filter is installed in a physical manner.

[0030] Specifically, it can be configured to prevent the operation of the laundry processing device if the external filter is not installed. For example, the laundry processing device of the utility model may include: a signal generating unit, which is combined with the filtering unit and generates a signal to the outside; a detection unit, which is configured to the installation unit and is configured to detect the signal generating unit; and a control unit, if the detection unit detects the signal generating unit, the control unit allows driving one or more of the heat supply unit and the driving unit; the signal generating unit can be set in the external filter.

[0031] When the external filter is installed separately, an elastic part for detaching the external filter may be provided. Thus, the external filter cannot be installed without installing the internal filter.

[0032] Specifically, the external filter may include: a seat body, which is placed on the mounting portion; and an insert body, which is provided with a mesh component extending from the seat body and filtering foreign matter, at least a portion of the insert body is inserted into the mounting portion; the elastomer may be arranged on the seat body.

[0033] The elastic portion may be configured to lead the seat body out of the mounting portion to prevent the door from closing the opening.

[0034] To this end, the seat body can be configured to protrude into the inlet through the elastic portion. The seat body can also include a placement platform, which further extends outward from the insert body and is placed on the top surface of the mounting portion, and the elastic portion is combined with the bottom surface of the placement platform and can be contacted with the top surface of the mounting portion.

[0035] The inner filter may further be provided with a coupling portion, which fixes the outer filter to the mounting portion to prevent it from being separated.

[0037] In addition, the mounting portion includes: a mounting groove, which passes through the inner circumferential surface of the inlet and supports the filter portion; and a mounting body, which extends from the mounting groove to the circulation pipe and accommodates the filter portion, and the outer circumferential surface of the mounting body is provided with the detection portion; the coupling portion may include a coupling hook, which protrudes to the side of the support body and can be loaded and unloaded to the inner surface of the mounting groove.

[0038] Specifically, the coupling portion includes a coupling rib, the coupling rib is configured to be able to move back and forth from the support body to the inner surface of the installation groove, and the coupling hook may be formed at a distal end of the coupling rib.

[0039] The combining portion includes: a plurality of combining ribs, which are configured to be able to move back and forth from the two sides of the support body to the inner surface of the mounting groove; and an elastic component, which is arranged between the plurality of combining ribs and pushes the plurality of combining ribs toward the two side surfaces of the support body; the combining hooks can be respectively formed at the ends of the plurality of combining ribs.

[0040] The plurality of combining ribs include: a pushing end combined with the elastic component; and an extending rib extending from the bottom of the pushing end to the two side surfaces of the supporting rib and having the combining hook at the end of the extending rib; the supporting body may include a guide box, which accommodates the elastic component on the top surface and exposes the pushing end on both sides.

[0041] A plurality of the coupling ribs may be arranged in the guide box at intervals by a length by which the coupling hook is separated from the mounting groove.

[0042] The support body may further include a moving rail extending in a width direction and guiding the plurality of coupling ribs.

[0043] When the coupling portion fixes the support body to the mounting portion, the detection portion may be disposed at a position facing the signal generation portion.

[0044] In order to solve the above problem, the laundry processing device of the present invention can be configured so that the installation relative to the installation portion can be completed only when any one of the external filter and the internal filter is installed on the installation portion where the other filter is set.

[0045] If the inner filter is mounted on the mounting portion alone, the inner filter is mounted in a shaky state and may not be fixed.

[0046] The internal filter includes: a support body, which is placed on the top surface of the external filter; and a housing body, which extends from the support body and is configured so that at least a portion of the housing body can be inserted into the external filter or the mounting portion; the support body is configured to shake on the top surface of the mounting portion if the support body is mounted on the mounting portion.

[0047] The outer filter may be configured to secure and accommodate the inner filter.

[0052] The signal generating portion may be configured to move toward the detecting portion when the external filter or the internal filter is seated on the mounting portion.

[0053] The signal generating unit may be disposed on an inner peripheral surface of the mounting portion, and may be disposed to be vertically movable toward the detecting unit through the external filter.

[0054] The signal generating unit may be disposed on an inner surface of the outer filter so as to move toward a bottom through the inner filter.

[0093] Figure 32 is a diagram showing the internal structure of the clothes processing device of the present invention.

[0094] The clothing processing device 100 includes: a housing 1; a drum 2, which is rotatably arranged inside the housing and provides a space for storing clothing; a circulation duct 3, which forms a flow path for supplying air exhausted from the drum 2 to the drum 2; and a heat exchange part 4, which dehumidifies and heats the air flowing into the circulation duct 3 and then supplies it to the drum 2.

[0095] When the drum 2 is configured as a cylindrical drum body 21 with its front and rear sides open, the box body 1 may include: a first support portion 17 rotatably supporting the front side of the drum 2; and a second support portion 19 rotatably supporting the rear side of the drum 2.

[0096] The first supporting portion 17 may include: a first fixing body 171 fixed inside the box body 1 ; and an input port 173 configured to pass through the first fixing body and communicate with the opening 111 and the inside of the drum body 21 .

[0097] The first supporting portion 17 may be configured to further include a first supporting body 175 that is disposed on the first fixing body 171 and inserted into the front of the drum body 21 .

[0098] The first fixed body 171 may be configured in any shape as long as it has the input port 173 and the first support body 175. The first support body 175 may be configured in a tubular shape protruding from the first fixed body 171 toward the drum body 21, and the diameter of the first support body 175 may be set to be larger than the diameter of the input port 173 and smaller than the front diameter of the drum body 21. In this case, the input port 173 will be located inside the space where the first support body 175 is formed.

[0099] The first support portion 17 may be configured to further include a connection body 177 connecting the opening portion 111 and the input port 173. The connection body 177 may be in a tubular shape configured to extend from the input port 173 to the opening portion 111. The connection body 177 may have a mounting portion 178 that communicates with the circulation duct 3. The mounting portion 178 is a duct that allows air inside the drum body 21 to move to the circulation duct 3, and may be configured to pass through the connection body 177.

[0100] The mounting portion 178 connects the inlet 173 and the circulation pipe 3 , and may be configured in a pipe shape, or may be configured in a shape in which one end is recessed in the inlet 173 .

[0101] The mounting portion 178 may be configured to allow the air discharged from the drum 2 to flow in, and the flowed air may pass through the mounting portion 178 and move toward the circulation duct 3 .

[0102] The second support portion 19 may be configured to include: a second fixing body 191 fixed to the inside of the housing 1; and a second support body 195 arranged on the second fixing body 191 and inserted into the rear surface (second open surface) of the drum body 21. The second support portion 19 has an air inlet 198, which passes through the second fixing body 191 and connects the inside of the drum body 21 with the inside of the housing 1. In this case, the circulation duct 3 may be configured to connect the mounting portion 178 and the air inlet 198.

[0103] The hollow cylindrical drum body 21 can be rotated by various driving parts. Figure 3 An example is shown in which the driving unit 28 is configured to include: a motor 23 fixed inside the housing 1 ; a pulley 25 rotated by the motor; and a belt 27 connecting the circumferential surface of the pulley 25 and the circumferential surface of the drum body 21 .

[0104] The first support portion 17 may include a first roller 179 rotatably supporting the circumferential surface of the drum body 21 , and the second support portion 19 may include a second roller 199 rotatably supporting the circumferential surface of the drum body.

[0105] The circulation duct 3 may be configured to include: an exhaust duct 31 connected to the mounting portion 178 ; a supply duct 33 connected to the air inlet 198 ; and a connection duct 35 connecting the exhaust duct and the supply duct.

[0106] The heat exchange part 4 may be composed of various devices that can sequentially dehumidify and heat the air flowing into the circulation duct 3. For example, the heat exchange part 4 may be composed of a heat pump system.

[0107] The heat exchange part 4 may include: a fan 49 that moves air along the circulation duct 3; a first heat exchanger (heat absorption part, 41) that removes moisture from the air flowing into the circulation duct 3; and a second heat exchanger (heat generation part, 43) that is arranged inside the circulation duct 3 and heats the air passing through the first heat exchanger 41.

[0108] The fan 49 may be configured to include: an impeller 491 disposed inside the circulation duct 3; and an impeller motor 493 for rotating the impeller 491. (See Figure 4 ) The impeller 491 can be arranged at any position in the exhaust pipe 31, the connecting pipe 35, and the supply pipe 33. Figure 3 An example is shown in which the impeller 491 is disposed in the supply duct 33 (a case in which the impeller 491 is located behind the heat generating portion).

[0109] The evaporator 41 may be composed of a plurality of metal plates arranged along the width direction (Y-axis direction) of the connecting pipe 35 or the height direction (Z-axis direction) of the connecting pipe, and the condenser 43 may be composed of a plurality of metal plates arranged along the width direction of the connecting pipe or the height direction of the connecting pipe. The evaporator 41 and the condenser 43 are sequentially arranged inside the connecting pipe 35 along the direction from the exhaust pipe 31 to the supply pipe 33, and are connected to each other through a condenser pipe 48 forming a circulation flow path of the condenser.

[0110] The refrigerant moves along the refrigerant pipe 48 by a compressor 45 located outside the circulation pipe 3 , and the refrigerant pipe 48 has a pressure regulator 47 therein for regulating the pressure of the refrigerant passing through the condenser 43 .

[0111] The evaporator 41 is a unit that cools the air and evaporates the condensing agent by transferring heat of the air flowing into the exhaust duct 31 to the condensing agent. The condenser 43 is a unit that heats the air and condenses the condensing agent by transferring heat possessed by the condensing agent passing through the compressor 45 to the air. In this case, moisture contained in the air is gathered along the surface of the evaporator 41 to the bottom surface of the connecting duct 35 when passing through the evaporator 41.

[0112] In order to collect moisture removed from the air passing through the evaporator 41 , the laundry treating apparatus 100 has a water collecting portion.

[0113] The water collected in the water collecting part is collected in the water storage part 7 and is subsequently discharged together. The water storage part 7 may be configured to include: a storage body 72 that can be detachably arranged on the housing 1 and provides a space for storing water; and an inlet 722 that is arranged to pass through the storage body 72 and allows the water discharged from the water storage part supply pipe 633 to flow into the storage body 72.

[0114] The storage body 72 may be formed by a drawer-shaped tank drawn out from the box body 1. In this case, the front panel 11 of the box body should have a water storage portion mounting hole into which the storage body 72 is inserted. A panel 71 is fixed to the front of the storage body 72. The panel 71 may be configured to be detachably coupled to the water storage portion mounting hole to form a part of the front panel 11.

[0115] The panel 71 may also have a groove 711 for inserting a user's hand. In this case, the panel 71 may also function as a handle for leading the storage body 72 out of the box or inserting the storage body into the box.

[0116] The inlet 722 may also be configured to receive water discharged from a nozzle 722a fixed to the housing 1. The nozzle 722a may be fixed to the top panel 13 of the housing so that the storage body 72 is located at the top of the inlet 722 when inserted into the housing 1.

[0117] The water storage part 7 having the above structure can be used by the user to flip or tilt the storage body 72 toward the inlet 722 after the user draws out the storage body 72 from the box body 1, thereby discarding the water inside the storage body 72. A connecting hole 721 passing through the top surface of the storage body 72 can also be configured to allow the water inside the storage body 72 to be easily discharged through the inlet 722.

[0118] On the other hand, the heat exchange part 4 is configured to condense moisture of the air circulating in the evaporator 41. Therefore, even if the air circulates in the drum 2, moisture is removed in the evaporator 41, so that the clothes inside the drum 2 can be continuously dried.

[0119] The water condensed in the evaporator 41 may be collected in the water storage part 7 for a second time after being collected in the water collecting part 37 for the first time. The water collecting part 37 may be located inside the connecting pipe 35 or may be separately arranged in a space separated from the connecting pipe 35 .

[0120] The laundry processing apparatus 100 may further include at least one of a filter unit and a filter unit for filtering air to minimize the accumulation of foreign matter (lint, etc.) discharged from the drum body 21 on the evaporator 41 and the condenser 43 .

[0121] The filter unit 10 may be configured as a unit for filtering air flowing from the drum body 21 into the exhaust duct 31, and the filter unit 5 is located between the filter unit 100 and the evaporator 41, and may be configured as a unit for filtering air passing through the second filter unit. The diameter of the filter hole configured in the filter unit 5 may be set to be smaller than the diameter of the filter hole configured in the filter unit 10.

[0122] The filter unit 10 may be detachably inserted into the exhaust duct 31 through the mounting portion 178 .

[0123] The filter unit 5 can be detachably arranged on the connecting pipe 35. In this case, the front panel 11 of the box body has an outlet hole (113, see Figure 1); opening and closing the outlet hole door 114 of the outlet hole; the circulation pipe 3 may have a pipe through hole (34, reference to Figure 3 ). Therefore, the user can separate the filter part 5 from the clothing processing device as needed to remove foreign matter remaining in the filter part 5 and wash the first filter part.

[0124] The filter section 5 can be configured to include: filter bodies 51, 53, 57, 58 that are inserted into the outlet hole 113 and the pipe through hole 34 and located between the filter section 10 and the evaporator 41; and filter components 531, 551, 571 that are arranged in the filter body and filter the fluid (air and water) moving toward the evaporator 41 and the water collecting body 371.

[0125] The filter element may be arranged in various forms according to the shape of the cross section (YZ plane and XZ plane) of the connecting pipe 35 .

[0126] In this case, the filter body can be configured to include: a front surface 51 configured to close the pipe through hole 34; a rear surface 53 located between the front surface and the evaporator 41; a bottom surface 55 configured to connect the front surface and the rear surface; a first side surface 57 and a second side surface 58 forming the left and right sides of the filter body.

[0127] The front face 51 may have a lock 513 (lock) that can be detachably coupled to a locking fastener 16 disposed on the housing. The lock 513 is composed of a bar rotatably coupled to the front face 51 of the filter body, and the locking fastener 16 may be configured to form a groove that accommodates the free end of the bar.

[0128] Preferably, the locks 513 are respectively disposed on two opposite sides of the front surface 51 , and the locking fastening portions 16 are respectively disposed on two opposite sides of the filter installation groove 113 .

[0129] The front surface 51 may also be provided with a handle 511 to facilitate the filter element to be inserted into or separated from the connecting pipe 35 .

[0130] The rear surface 53 and the bottom surface 55 may respectively include a first filter component 531 and a second filter component 551 for filtering the fluid (air and water) flowing into the filter body. The rear surface 53 has a rear surface through hole that connects the interior of the filter body with the internal space of the circulation pipe 3, and the filter component 531 is arranged in the rear surface through hole. The bottom surface 55 has a bottom surface through hole that connects the interior of the filter body with the internal space of the circulation pipe 3, and the second filter component 551 is arranged in the bottom surface through hole. Therefore, the first filter component 531 is a unit for filtering the fluid (air and water) supplied to the evaporator 41, and the second filter component 551 is a unit for filtering the fluid supplied to the water collecting body 371.

[0131] The first side surface 57 and the second side surface 58 may be configured to connect the front surface 51 , the rear surface 53 , and the bottom surface 55 .

[0132] The filter part 5 having the above-mentioned structure may be configured to communicate with the exhaust pipe 31 through the top surface or the second side surface 58 of the filter part body.

[0133] The filter unit 5 may be connected to the exhaust duct 31 via a top surface through-hole configured to pass through the top surface of the filter unit body and a side surface through-hole configured to pass through the second side surface 58 .

[0134] The first filter element 531 may be configured to be inclined 90 to 100 degrees toward the front of the evaporator 41 based on the bottom surface 55 of the filter element body. This is to facilitate the movement of foreign matter remaining in the first filter element to the bottom surface 55 when water is sprayed onto the first filter element 531 through the moving part 6 described later.

[0135] The second filter component 551 may be configured to be tilted downward by 10 to 20 degrees from the front surface 51 toward the first filter component 531 (the second filter component may be tilted upward by 10 to 20 degrees from the bottom end of the first filter component toward the direction where the outlet hole is located). When the second filter component 551 is configured to be tilted downward toward the first filter component 531, the connection between the first filter component 531 and the second filter component 551 becomes the lowest position in the space provided by the first filter part, so that foreign matter in the first filter part 5 may be concentrated at the connection between the first filter component 531 and the second filter component 551. When foreign matter is concentrated at the connection between the first filter component 531 and the second filter component 551, the user can more easily remove foreign matter inside the filter part 5.

[0136] However, when foreign matter is concentrated at the connection between the first filter component 531 and the second filter component 551, it may take a long time for the water ejected through the moving part 6 to be discharged to the water collecting body 371. In order to solve this problem, the first side surface 57 may also have a diversion hole that connects the inside of the filter part 5 with the water collecting body 371 and a third filter component 571 disposed in the diversion hole.

[0137] The diverter hole and the third filter component 571 may be disposed at a position higher than the top of the second filter component 551 and lower than the top of the first filter component 531. Therefore, the laundry treatment device can minimize the phenomenon that the water ejected into the filter part 5 due to foreign matter remaining in the filter part 5 cannot be recovered to the water collecting body 371.

[0138] On the other hand, the laundry treatment apparatus 100 may include: a moving part 6 utilizing the water stored in the water collecting body 371; and a discharge part 900 coupled to the moving part 6 and receiving the supplied water to wash the evaporator 41 or the first filter part 5.

[0139] The water stored in the water collecting body 371 can be collected in the water storage part 7 alone, or can be selectively moved to the moving part 6 .

[0140] The moving part 6 may also be configured to move water for washing at least any one of the filter part 5 and the evaporator 41 by spraying the water stored in the water collecting body 371 to the first filter part 5 .

[0141] The moving part 6 may be disposed in the circulation pipe 3 and supply water to the discharge part 900, and the discharge part 900 supplies water to the filter part 5 or the evaporator 41. The moving part 6 may be configured to include a washing pump 61 that moves the water stored in the water collecting body 371 to the discharge part 900.

[0142] The washing pump 61 may be connected to the water collecting body 371 through a first connecting pipe 611, and connected to the discharge part 65 through a second connecting pipe 613. When the laundry processing device is configured to move the water of the water collecting body 371 to the discharge part 65 and the water storage part 7 through only one washing pump 61, a flow path conversion part 63 may be further configured on the laundry processing device 100. In this case, the flow path conversion part 63 may be connected to the washing pump 61 through the second connecting pipe 613, the discharge part 65 may be connected to the flow path conversion part 63 through a spray part supply pipe 631, and the water storage part 7 may be configured to be connected to the flow path conversion part 63 through a water storage part supply pipe 633.

[0143] In this case, the water storage unit supply pipe 633 should be configured to connect the nozzle 722 a and the flow path conversion unit 63 .

[0144] The flow path conversion part 63 has a valve for controlling the opening and closing of the injection part supply pipe 631 and the opening and closing of the water storage part supply pipe 633. Therefore, the laundry processing apparatus 100 can supply the water stored in the water collecting body 371 to the discharge part 65 or the water storage part 7 by controlling the valve disposed in the flow path conversion part 63.

[0145] The injection unit supply pipe 631 may be configured to be coupled to the connection pipe 35, or may be coupled to a surface corresponding to the top surface of the evaporator 41. Thus, the water supplied to the injection unit supply pipe 631 can be discharged to the evaporator 41 or the first filter unit 5 to remove foreign matter attached to the evaporator 41 or the filter unit 5.

[0146] On the other hand, the moving part 6 may also be configured to receive not only the water condensed in the evaporator 41 but also fresh water directly from the water supply part 300. In this case, there may be a pipe directly connecting the water supply part 300 and the moving part 6. For example, there may also be a separate pipe connecting the steam part 200 and the moving part 6.

[0147] The laundry processing device 100 may include a dryness detection unit to determine the operation interruption time point of the heat exchange unit 4 by determining the dryness of the laundry. The dryness detection unit may be composed of at least one of an electrode sensor that is arranged in contact with the laundry and measures the amount of moisture contained in the laundry, and a humidity sensor that measures the humidity of the air flowing from the drum 2 into the circulation duct 3.

[0148] The laundry processing device 100 can determine the dryness of the laundry by observing the resistance measured when the electrode sensor is connected to the laundry. On the other hand, as the dryness of the laundry increases, the amount of moisture contained in the air flowing into the circulation duct 3 decreases, so the laundry processing device 100 can also observe the humidity of the air flowing into the circulation duct 3 through the humidity sensor, thereby being able to determine the dryness of the laundry.

[0149] On the other hand, the drum body 21 may further include a drum back side coupled to the back side and closing the back side of the drum body 21, and the driving unit may further be configured to be coupled to the drum back side and directly rotate the drum body 21. In this case, the driving unit may be coupled to the second supporting unit 19 and supported.

[0150] The present invention describes a case where the driving unit is configured to include: a motor 23 fixed inside the housing 1; a pulley 25 rotated by the motor; and a belt 27 connecting the circumferential surface of the pulley 25 and the circumferential surface of the drum body 21 as an example.

[0151] On the other hand, the first support part 17 may include a first roller 179 rotatably supporting the circumferential surface of the drum body 21 , and the second support part 19 may include a second roller 199 rotatably supporting the circumferential surface of the drum body.

[0152] The water collecting portion 126 of the base 12 may have a water collecting chamber 127 fixed to the bottom surface of the connecting pipe 35 and communicating with the inside of the connecting pipe 35. A heat exchanger support portion 128 may also be provided inside the water collecting chamber 127 so that the heat absorbing portion 41 and the heat generating portion 43 do not contact the water (condensed water) stored in the water collecting chamber 127. The heat exchanger support portion 128 may maintain the spacing between the heat absorbing portion 41 and the heat generating portion 43 and the bottom surface of the water collecting chamber 127.

[0153] The heat exchanger support 128 supporting the heat absorbing part 41 and the heat generating part 43 may be formed with a plurality of support plate through holes (not shown) corresponding to the positions of the heat absorbing parts. The support plate through holes may guide the water generated in the heat absorbing part 41 and / or the water for washing the heat absorbing part 41 to flow to the water collecting chamber 127.

[0154] On the other hand, in the case of the clothes dryer 100 according to the present invention, a washing section 6 for washing the heat absorption section 41 using water stored in the water collecting chamber 127 and a drainage section 7 for discharging water inside the water collecting chamber 127 to the outside of the water collecting chamber 127 can also be configured.

[0155] The washing unit 6 may be configured as a unit for washing the heat absorbing unit 41 by spraying the water stored in the water collecting chamber 127 to the heat absorbing unit 41. The washing unit 6 may include a spraying unit 65 disposed in the circulation pipe 3 and supplying water to the heat absorbing unit 41; and a pump 61 for moving the water stored in the water collecting chamber 127 to the spraying unit 65.

[0156] The pump 61 connects the water discharged from the water collecting chamber 127 to the injection part 65 through the second connection pipe 613. The pump 61 and the water collecting chamber 127 are located adjacent to each other and the water in the water collecting chamber 127 is moved or connected through a separate first connection pipe 611.

[0157] On the other hand, when the clothes dryer 100 moves the water in the water collecting chamber 127 to the spraying part 65 and the drain part 7 by only one pump 61 , the clothes dryer 100 may further include a flow path conversion part 63 .

[0158] In this case, the flow path conversion part 63 can be connected to the pump 61 through the second connecting pipe 613, the injection part 65 can be connected to the flow path conversion part 63 through the injection part supply pipe 631, and the drain part 7 can be connected to the flow path conversion part 63 through the drain part supply pipe 633.

[0159] The flow path conversion part 63 may have a valve (shown in the figure) for controlling the opening and closing of the injection part supply pipe 631 and the opening and closing of the drainage part supply pipe 633. Therefore, the clothes dryer 100 can supply the water stored in the water collecting chamber 127 to the injection part 65 or to the drainage part 7 by controlling the valve disposed in the flow path conversion part 63.

[0160] The drain 7 may include: a storage body 72 detachably disposed on the housing 1 to provide a space for storing water; and an inlet 722 disposed through the storage body 72 to allow water discharged from the drain supply pipe 633 to flow into the storage body 72 .

[0161] The storage body 72 may be configured as a drawer-shaped tank drawn out from the box body 1, in which case the front panel 11 of the box body must have a drain installation hole for inserting the storage body 72. A panel 71 is fixed to the front of the storage body 72, and the panel 71 is detachably coupled to the drain installation hole to form a part of the front panel 11.

[0162] The panel 71 may also have a groove 711 for inserting a user's hand. In this case, the panel 71 also serves as a handle for leading or inserting the storage body 72 from the box.

[0163] The inlet 722 may be configured to receive water discharged from a nozzle 722a fixed to the housing 1. The nozzle 722a may be fixed to the top panel 13 of the housing so that the storage body 72 is located at the top of the inlet 722 when the storage body 72 is inserted into the housing 1. In this case, the drain supply pipe 633 is configured to connect the nozzle 722a and the flow path conversion unit 63.

[0164] After the user draws out the storage body 72 from the housing 1 , the drainage unit 7 having the above structure turns or tilts the storage body 72 in the direction where the inlet 722 is located, thereby discarding the water inside the storage body 72 .

[0165] Here, a communication hole 721 may be provided through the top surface of the storage body 72 so that water inside the storage body 72 can be easily discharged through the inlet 722 .

[0166] On the other hand, the clothes dryer 100 may further include a water collecting part water level detection unit (not shown) for measuring the water level of the water collecting chamber 127. The water collecting part water level detection unit may determine the time point for moving the water stored in the water collecting chamber 127 to the storage body 72, thereby preventing the water in the water collecting chamber 127 from flowing back to the connecting pipe 35.

[0167] In addition, the clothes dryer 100 may further include a dryness detection unit (not shown) for determining the dryness of the clothes. The dryness detection unit may be composed of at least one of an electrode sensor (not shown) that contacts the clothes and measures the amount of moisture contained in the clothes and a humidity sensor (not shown) that measures the humidity of the air flowing from the drum 2 into the circulation duct 3.

[0168] In addition, clothes dryer 100 may further include a temperature detection unit (not shown) for detecting the temperature of air flowing into circulation duct 3 .

[0169] On the other hand, the drum 2, circulation pipe 3, heat exchange section 4, washing section 6 and drainage section 7 as described above are supported and arranged by a base 12 located at the bottom of the box body 1. In the base 12, condensed water generated in the heat exchange section 4, washing water in the washing heat absorption section 41 of the washing section 6, etc. can be collected in the water collection chamber 127 of the water collection section 126 and supplied to the injection section 65 or the drainage section 7 through the pump 61.

[0170] On the other hand, in order to minimize the accumulation of foreign matter (lint, etc.) discharged from the drum body 21 on the heat absorbing part 41 and the heat generating part 43 , the laundry processing apparatus further includes the filter part 10 .

[0171] The filter unit 10 filters foreign matter discharged from the drum 2 and is easily exposed to the input port 173 , so that the user can remove the accumulated foreign matter at any time.

[0172] The filter unit 10 is detachably inserted into the exhaust duct 31 through the mounting portion 178 , and can filter lint included in the air flowing into the mounting portion 178 .

[0173] As a result, the number of times the filter part 5 is replaced or removed can be greatly reduced.

[0174] Hereinafter, the structures of the mounting portion 178 and the filter portion 10 will be described in detail with reference to the drawings.

[0175] Figure 4 2 is a diagram showing a state where a filter unit according to an embodiment of the present invention is installed.

[0176] A mounting portion 178 is formed at the bottom of the connecting body 177 of the first supporting portion 17 , and the mounting portion 178 is provided with the filter portion 10 .

[0177] The mounting portion 178 may be configured to pass through the connector 177 and communicate with the circulation pipe 3 .

[0178] The mounting portion 178 is configured to communicate with the inlet 173 and the circulation duct 3 , thereby providing a flow path through which the air exhausted from the drum 2 passes for the first time.

[0179] The installation portion 178 may be configured in a pipe shape on the first support portion 17 , and may provide a space for accommodating and installing the filter unit 10 .

[0180] The filter unit 10 may be configured to be mounted on the mounting portion 178 and allow the air to pass therethrough while filtering lint and foreign matter contained in the air.

[0181] The filter unit 10 is installed at the installation portion 178 and may include an internal filter 100 for filtering foreign matter from the air discharged from the drum 2 .

[0182] The internal filter 100 may be installed on the installation portion 178 to form the inner circumferential surface of the inlet 173 , and may not protrude from the inner circumferential surface of the inlet 173 toward the inside of the inlet 173 .

[0183] In addition, the internal filter 100 may be configured to have an area or shape corresponding to the inlet shape of the mounting portion 178. Thus, the distance between the internal filter 100 and the mounting portion 178 is minimized, thereby preventing foreign matter or a portion of clothing from being inserted between the internal filter 100 and the mounting portion 178.

[0184] The filter unit 10 may further include an external filter 200 installed on the installation portion 178 from the bottom of the internal filter 100 and filtering foreign matter.

[0185] The external filter 200 may be disposed downstream of the internal filter 100 in the flow path and further filter lint and foreign matter that are not filtered by the internal filter 100 .

[0186] Thus, the filter unit 10 can more reliably remove foreign matter such as lint from the air discharged from the drum 2 .

[0187] When the external filter 200 is mounted on the mounting portion 178 , it is possible for the external filter 200 not to be exposed from the input port 173 .

[0188] Figure 5 It is a figure which shows the state which led out the said filter part.

[0189] The filter unit 10 is detachably disposed on the mounting portion 178 .

[0190] The filter unit 10 is mounted on the mounting portion 178 to filter foreign matter, and the filtered foreign matter is drawn out and discharged from the mounting portion 178 .

[0191] The mounting portion 178 may include: a mounting hole 1781 that passes through the connecting body 177 or the bottom surface of the inlet 173 and allows air to flow into the drum 2 and form an inlet of the mounting portion 178 ; and a mounting body 1782 that forms an inner circumferential surface of the mounting portion 178 .

[0192] The mounting hole 1781 may be configured to be larger than an area of ​​the mounting body 1782 , and the mounting body 1782 may form a step in the mounting hole 1781 and may extend to the circulation duct 3 .

[0193] The inlet area of ​​the mounting body 1782 may be configured to be smaller than the area of ​​the mounting hole 1781 , and the top surface of the mounting body 1782 may be configured to support the bottom of the filter unit 10 .

[0194] The filter unit 10 may be supported by the mounting body 1782 , thereby being prevented from being separated from the circulation pipe 3 .

[0195] On the other hand, at least a portion of the inner filter 100 may be accommodated in the outer filter 200 .

[0196] Thus, the space occupied by the internal filter 100 and the external filter 200 can be reduced to the maximum extent, thereby minimizing the volume of the filter unit 10 .

[0197] In addition, the user may be guided to integrally lead out the internal filter 100 and the external filter 200 or simultaneously install them on the installation portion 178 .

[0198] Figure 6 1 is a diagram showing a specific structure of the filter unit 10 .

[0199] The internal filter 100 may include: a support body 110 disposed and supported by the mounting portion 178 ; and a receiving body 120 extending from the support body 110 toward the bottom and receiving at least a portion of the external filter 200 or the mounting portion 178 .

[0200] The support body 110 may be configured to correspond to the shape and area of ​​the mounting hole 1781 and to form a portion of the input port 173 .

[0201] The support body 110 may include: an open surface 112 through which air and foreign matter can flow; and a plurality of blocking ribs 111 configured to close at least a portion of the open surface 112 .

[0202] The blocking ribs 111 may be configured to block larger objects such as clothes, except for small foreign objects such as air or lint, from flowing into the open surface 112. The blocking ribs 111 may be configured on the open surface 112 like a net.

[0203] On the other hand, the top surface of the support body 110 may include a coupling portion 160 for coupling the support body 110 to the mounting portion 178 or guiding the placement and extraction direction of the internal filter 100 .

[0204] The area of ​​the support body 110 may be configured to be larger than the area of ​​the receiving body 120 .

[0205] The support body 110 may include a placement surface 113 at the bottom further extending outward from the top surface of the accommodating body 120. The placement surface 113 is supported at the top of the mounting hole 1781, thereby preventing the internal filter 100 from falling into the mounting hole 1781.

[0206] The receiving body 120 is configured in a box shape and may provide a space extending from the bottom of the supporting body 110 and accumulating foreign substances therein.

[0207] Most of the area of ​​the container 120 may be configured as through holes, and a net portion 140 coupled to the through holes and capable of filtering the foreign matter on the surface may be provided.

[0208] The net 140 may be configured to have a mesh shape that blocks the through holes passing through the housing 120. The net 140 may be configured to occupy most of the surface area of ​​the housing 120. Due to the net 140, the housing 120 may be in the shape of a frame that supports the net 140.

[0209] The container 120 may include: a first container 121 extending from the bottom of the support body 110 and filtering foreign matter; and a second container 122 rotatably disposed at the bottom of the first container 121 and forming a space for accumulating foreign matter together with the first container 121 .

[0210] In other words, the first container 121 and the second container 122 are separated from each other and the interior of the container 120 is open. Therefore, the user can remove foreign matter that is filtered by the first container 121 and the second container 122 and accumulated in the container 120.

[0211] Of course, not only the container 120 but also the support 110 may be configured to be separable from each other. The support 110 may be configured such that a portion coupled with the first container 121 and a portion coupled with the second container 122 are detachable from each other.

[0212] The internal filter 100 may further include a reinforcement portion 150 for reinforcing the first housing body 121 and the second housing body 122 .

[0213] The reinforcing portion 150 can prevent the first accommodating body 121 and the second accommodating body 122 from being deformed when being inserted into the mounting portion 178 .

[0214] The reinforcing portion 150 may be arranged to be parallel to the width direction of the supporting body 110 and may be arranged in a rib shape. The reinforcing portion 150 may also function as a hinge for rotating the first receiving body 121 and the second receiving body 122 .

[0215] Although the figure shows that the first container 121 and the second container 122 extend from the bottom of the support body 110 in a wedge shape, the first container 121 and the second container 122 can be configured in any shape as long as they can have a space for accumulating foreign matter inside.

[0216] The external filter 200 may include: a seat body 210 installed in the installation portion 178 ; and an insert body 220 extending from the seat body 210 toward the bottom and at least a portion of which is inserted into the installation portion 178 or accommodates the internal filter 100 .

[0217] The seat body 210 may include an open surface 211 at the top through which the air and foreign matter can flow in, and may include a placement table 250 placed on the top of the installation body 1782 and supported.

[0218] The open surface 211 may be formed as an area into which the receiving body 120 of the inner filter 100 is inserted and received.

[0219] The mounting platform 250 is configured to be larger than the area of ​​the mounting body 1782 and smaller than the area of ​​the mounting hole 1781 , and is mounted on the top surface of the mounting body 1782 and supported while being received in the mounting hole 1781 .

[0220] The inserting body 220 may be configured to extend from the inner circumference of the mounting table 250 toward the bottom and be insertable into the mounting body 1782 .

[0221] The inserting body 220 may be configured in a box shape providing a space inside which foreign matter is accumulated.

[0222] Most of the area of ​​the insert 220 may be configured as a through hole, and a net 240 coupled to the through hole and capable of filtering foreign matter may be configured. The net 240 is composed of a net member or the like to allow air to pass through but filter foreign matter.

[0223] The mesh size of the net 240 may be configured to be smaller than the mesh size of the net portion 140 .

[0224] Thus, the inner filter 100 can filter relatively large foreign matter, and the outer filter 200 can filter relatively small foreign matter, so that the performance of the filter unit 100 in filtering foreign matter can be maximized.

[0225] The inserting body 220 may include: a first inserting body 221 extending from the bottom of the seat body 210 and filtering foreign matter; and a second inserting body 222 rotatably disposed at the bottom of the first inserting body 221 and forming a space for accumulating foreign matter together with the first inserting body 221 .

[0226] In other words, the inserting body 220 may be configured such that the first inserting body 221 and the second inserting body 222 are separated from each other and the inside is open. Therefore, the user can remove foreign matter filtered in the first inserting body 221 and the second inserting body 222.

[0227] Of course, not only the inserting body 220 but also the base body 210 may be configured to be separable from each other. The base body 210 may be configured such that a portion coupled with the first inserting body 221 and a portion coupled with the second inserting body 222 are detachable from each other.

[0228] The external filter 200 may further include a rigid portion 250 that strengthens the rigidity of the first insertion body 221 and the second insertion body 222 and maintains the shapes of the first insertion body 221 and the second insertion body 222 when they are inserted into the mounting portion 178 .

[0229] The rigid portion 250 may be configured as a rib shape extending in a width direction of the seat body 210 .

[0230] As described above, since the sizes of foreign matter filtered by the internal filter 100 and the external filter 200 are different, the internal filter 100 and the external filter 200 must be installed on the installation portion 178 at the same time.

[0231] For example, when only the inner filter 100 is mounted on the mounting portion 178, relatively small foreign matter all passes through the inner filter 100 and the function of the filter portion 10 cannot be guaranteed. In addition, when only the outer filter 100 is mounted on the mounting portion 178, foreign matter accumulates in the outer filter 200 and there is a problem of preventing the air discharged from the drum 2 to the outer filter 200 from flowing into the circulation duct 3.

[0232] Therefore, it is necessary to operate the laundry treating apparatus in a state in which the inner filter 100 and the outer filter 200 are all mounted on the mounting portion 178 .

[0233] Figure 7 This is a diagram showing an example in which both the external filter 200 and the internal filter 100 are mounted on the mounting portion 178 .

[0234] The laundry treating apparatus of the present invention may be configured to operate only when both the internal filter 100 and the external filter 200 are installed.

[0235] Specifically, the laundry processing apparatus of the present invention may be configured such that the installation of either the internal filter 100 or the external filter 200 is completed only when the other one is installed on the installation portion 178 .

[0236] In other words, the inner filter 100 alone may not be installed with respect to the installation portion 178 , and the outer filter 200 alone may not be installed with respect to the installation portion 178 .

[0237] For example, when the external filter 200 is not present, the internal filter 100 cannot be installed relative to the installation portion 178 in terms of physical structure.

[0238] In addition, when the internal filter 100 is not present, the external filter 200 cannot be installed relative to the installation portion 178 in terms of physical structure.

[0239] The fact that the internal filter 100 and the external filter 200 are not completely installed with respect to the installation portion 178 means that the internal filter 100 and the external filter 200 are shaken or vibrated when they are installed in the installation portion 178 .

[0240] In addition, the fact that the internal filter 100 and the external filter 200 are not completely installed in the installation portion 178 means that the internal filter 100 and the external filter 200 are not completely installed in the installation portion 178 but are drawn out to the inlet 173 .

[0241] Thus, when the user installs only one of the internal filter 100 and the external filter 200 on the installation portion 178, the user can recognize that the installation of the filter unit 10 is not completed. As a result, the laundry processing apparatus of the present invention can guide the user to install the other of the internal filter 100 and the external filter 200 on the installation portion 178.

[0242] In particular, the laundry processing apparatus of the present invention can physically recognize whether the internal filter 100 or the external filter 200 is installed separately before detecting whether the filter unit 10 is installed by an electrical control method such as a detection unit or a signal generation unit.

[0243] Therefore, even in a state where power is not supplied to the laundry treating apparatus, it can be confirmed whether the internal filter 100 or the external filter 200 is installed alone.

[0244] Reference Figure 7 When the internal filter 100 is not installed on the installation portion 178 , the external filter 200 may be configured to be led out from the installation portion 178 .

[0245] The external filter 200 may be drawn out from the mounting portion 178 toward the inlet 173. In other words, the external filter 200 may be configured such that at least a portion thereof is detached from the mounting portion 178 before the internal filter 100 is mounted on the mounting portion 178.

[0246] The external filter 200 may protrude from the mounting portion 178 to a certain extent so as to hinder the door 112 from closing the opening 111. Therefore, when only the external filter 200 is mounted on the mounting portion 178, the door 112 is hindered by the external filter 200 and cannot close the opening 111, so the laundry treating apparatus itself cannot operate.

[0247] Thus, when only the external filter 200 is installed in the installation portion 178 , the user finds that the external filter 200 is not completely installed in the installation portion 178 , and thus can recognize that the internal filter 100 needs to be installed.

[0248] In particular, regardless of whether the external filter 200 is installed or whether the internal filter 100 is installed, it is possible to confirm whether the installation of the external filter 100 is completed by simply confirming whether the door 112 itself can be closed.

[0249] The external filter 200 may further include an elastic portion 260 supported by the mounting portion 178 and allowing the external filter 200 to be separated from the mounting portion 178. The elastic portion 260 may be made of an elastic material such as a spring, and may be configured to allow the external filter 200 to be drawn out from the mounting portion 178.

[0250] Figure 8 2 is a diagram showing a specific structure of the external filter 200 .

[0251] The external filter 200 may include: a seat body 210 disposed on the mounting portion 178; a net member extending from the seat body and filtering foreign matter; and an inserting body 220 at least a portion of which is inserted into the mounting portion.

[0252] The elastic portion 260 may be configured to be coupled to the seat body 210 and to cause the seat body to be detached from the mounting portion 178 .

[0253] Of course, the elastic portion 260 can also be configured to be combined with the top surface of the mounting portion 178 and push the seat body 210 away.

[0254] The seat body 210 further includes a placement platform 250 further extending outward from the insert body 220 and placed on the top surface of the mounting portion.

[0255] The mounting platform 250 is configured to be mounted on the top surface of the mounting body 1782 , and the inserting body 220 is configured to be accommodated inside the mounting body 1782 .

[0256] The mounting table 250 may be configured to be integrated in a shape parallel to the top surface of the mounting body 1782 .

[0257] The elastic portion 260 may be configured such that a bottom surface of the seating platform 250 and a top surface of the mounting portion 178 are pushed away from each other.

[0258] The elastic portion 260 may be configured to be supported by a bottom surface of the mounting platform 250 and a top surface of the mounting body 1782 .

[0259] The mounting portion 178 may further include a supporting surface 1783 extending from the top of the mounting body 1782 toward the inner circumference of the mounting hole 1781 .

[0260] The elastic portion 260 may be coupled to one of the support surface 1783 and the bottom surface of the mounting table 250 and may be disposed in contact with the other one.

[0261] When the elastic portion 260 is combined with the bottom surface of the placement platform 250 , the elastic portion 260 may be combined with the bottom surfaces of both side surfaces of the placement platform 250 .

[0262] Thus, the seat body 210 can be prevented from tilting to one side and being drawn out from the mounting portion 178 .

[0263] The elastic portion 260 may be configured with a sufficient length so that the seat body 210 is located closer to the top than the mounting hole 1781 .

[0264] On the other hand, the external filter 200 may include a signal generating unit 300 for generating a signal, and the mounting unit 178 may include a detecting unit 400 for detecting the signal generating unit 300 .

[0265] The detection unit 400 may be composed of a Hall effect sensor, and the signal generation unit 300 may include a magnetic body that generates a magnetic field.

[0266] The signal generating unit 300 may be combined with the inserting body 220 , or may be disposed on a side surface of the inserting body 220 .

[0267] The detection unit 400 is disposed on the outer surface of the mounting body 1782 , thereby preventing interference with the external filter 200 .

[0268] When the external filter 200 is completely installed in the installation portion 178 , the detection portion 400 and the signal generation portion 300 may be arranged at the same height as each other.

[0269] When the detection part 400 detects the signal generation part 300, the control part may operate the laundry treating apparatus.

[0270] Therefore, when the elastic portion 260 pushes the mounting table 250 upward and the external filter 200 is drawn out from the mounting portion 178, the signal generating portion 300 may be separated from the detecting portion 400 and the laundry treating apparatus may not be able to perform its operation.

[0271] In particular, the control unit may be configured not to operate the laundry treating apparatus when the door 112 opens the opening 111 .

[0272] Therefore, in the laundry processing apparatus of the present invention, when the external filter 200 is inserted into the mounting portion 178 without the internal filter 100, the mounting itself relative to the mounting portion 178 may not be achieved, and the laundry processing apparatus itself does not operate.

[0273] Furthermore, when the signal generating unit 300 is not provided on the internal filter 100 , when the internal filter 100 is mounted on the mounting portion 178 without the external filter 200 , the laundry treating apparatus itself may not operate.

[0274] As a result, the laundry processing apparatus of the present invention can be configured to operate only when the internal filter 100 and the external filter 200 are all installed in the installation portion 178 , and the internal filter 100 and the external filter 200 can be forcibly guided to be installed in the installation portion 178 together.

[0275] Fig. 9 FIG. 2 is a diagram showing an example in which the elastic portion 260 is compressed.

[0276] When the seat body 210 is pressed to the bottom, the elastic part 260 may be pressed. The seat body 210 may pressurize the mounting part 178 by an external force such as a user, or the mounting part 178 may be pressurized by the internal filter 100 being placed at the top.

[0277] The insert 220 may be inserted deeper into the mounting body 1782 when the seat body 210 is pressurized.

[0278] The signal generating unit 300 coupled to the inserting body 220 moves toward the bottom together with the inserting body 220 and is arranged at a position overlapping with the detecting unit 400. Therefore, the laundry treating apparatus can be switched to an operable state.

[0279] However, when the external force on the seat body 210 disappears, the seat body 210 is again drawn out from the mounting portion 178 due to the elastic force of the elastic portion 260 .

[0280] In addition, since the detection unit 400 and the signal generation unit 300 are separated and the detection unit 400 cannot detect the signal generation unit 300, the laundry treating apparatus may not be able to operate.

[0281] Therefore, the inner filter 100 may be configured to overcome the restoring force of the elastic portion 260 and maintain a state in which the outer filter 200 is mounted on the mounting portion 178 .

[0282] Fig.10 FIG. 1 is a diagram showing a state in which the inner filter 100 and the outer filter 200 are installed.

[0283] Fig.10 (a) shows a state where the internal filter 100 is placed on the external filter 200. Fig.10(a) shows a state in which the inner filter 100 and the outer filter 200 are completely installed in the installation portion 178 .

[0284] The inner filter 100 may further include a coupling portion 160 that fixes the support body 110 to the mounting portion 178 and maintains the elastic portion 260 in a pressurized state.

[0285] The inner filter 100 may be accommodated and disposed on the outer filter 200 .

[0286] When the inner filter 100 applies pressure to the outer filter 200 , the elastic portion 260 is compressed, and the seat body 210 of the outer filter 200 can be placed on the mounting body 1782 .

[0287] At this time, the coupling portion 160 can couple the internal filter 100 to the mounting portion 178 and fix the positions of the internal filter 100 and the external filter 200. As a result, the external filter 200 can be completely mounted on the mounting portion 178, and the internal filter 100 can also be completely mounted on the mounting portion 178 through the coupling portion 160.

[0288] The coupling portion 160 may be detachably disposed on the mounting portion 178 , and the internal filter 100 may be fixed to the mounting portion 178 .

[0289] The coupling portion 160 may be coupled to an inner surface of the mounting hole 1781 located closer to the top than the mounting body 1782 .

[0290] The coupling portion 160 may be configured to protrude from the support body 110 , and may include a coupling hook 1613 protruding from at least one of two side surfaces of the support body 110 .

[0291] The internal filter 100 may include a seating surface 113 seated in the mounting hole 1781 .

[0292] Both side surfaces of the placement surface 113 may be configured to form a portion of the inner circumference of the input port 173 .

[0293] The placement surface 113 may be configured to close an entrance of the mounting portion 178 , and may be configured to form a portion of the connecting body 177 .

[0294] When the internal filter 100 is completely installed in the installation portion 178 , the internal filter 100 may form a continuous surface between the inner circumferential surface of the connecting body 177 and the top surface of the supporting body 110 , and the top surface of the supporting body 110 may form a portion of the inlet 173 .

[0295] Thus, a door structure such as a door gasket disposed on the door 112 and inserted into the input port 173 may not interfere with the support body 110 .

[0296] As a result, the door 112 can close the opening 111 without being interfered by the support body 110. On the other hand, when the internal filter 100 is completely installed in the mounting portion 178 through the coupling portion 160, the elastic portion 260 can be kept in a state of being pressurized. Since the internal filter 100 is fixed to the mounting portion 178, the elastic portion 260 cannot push the external filter 200 away, and the external filter 200 can be kept in a state of being pressurized. As a result, the external filter 200 cannot be drawn out to the inlet 173 and can be kept in a state of being completely installed in the mounting portion 178.

[0297] Specifically, the support body 110 is disposed on the seat body 210 to transmit an external force that pressurizes the elastic portion 260 , and the coupling portion 160 may be configured to protrude from two side surfaces of the support body 110 .

[0298] The receiving body 120 provided with a net member extending from the supporting body 110 and filtering foreign matter is at least partially inserted into the external filter 200 during the process of the supporting body 110 being placed on the seat body 210 .

[0299] On the other hand, the inner filter 100 may be configured in a shape corresponding to the shape of the mounting hole 1781 .

[0300] However, the internal filter 100 may be configured such that, when the internal filter is separately mounted on the mounting portion, the internal filter cannot be integrated with the mounting portion or is mounted in a shaky manner.

[0301] For example, although the outer surface of the inner filter 100 may be configured in a shape corresponding to the mounting hole 1781 , the bottom surface of the inner filter 100 and the inlet of the mounting hole 1781 are configured to be shaky.

[0302] The cross-sectional area of ​​the container 120 is configured to be much smaller than the cross-sectional area of ​​the mounting pipe 1782, so that when only the container 120 is accommodated in the mounting pipe 1782, the container 120 can be configured to rock forward or backward.

[0303] For example, the inner filter 100 may swing relative to the coupling portion 160 .

[0304] The surface of the support body 110 may be configured to create a sense of unity with the connection body 177 , but the seating surface 113 of the support body 110 and the outer peripheral surface of the mounting hole 1781 may not be precisely integrated.

[0305] For example, the placement surface 113 may be configured to close the mounting hole 1781 , but may be configured to rock on the outer peripheral surface of the mounting hole 1781 when the housing body 120 rocks.

[0306] The bottom surface of the placement surface 113 may be configured as a curved surface along the thickness direction or the front-rear direction of the input port 111 , and the perimeter of the mounting hole 1781 may also be configured so that the placement surface 113 is rockable.

[0307] Therefore, when the housing body 120 is shaken inside the mounting pipe 1782 , the support body 110 may also be shaken in the mounting hole 1781 .

[0308] Thus, since the internal filter 100 cannot be fixed to the mounting hole 1781 , the user can recognize that the external filter 200 is needed, and thus the internal filter 100 can be combined with the external filter 200 .

[0309] The outer filter 200 may accommodate the inner filter 100 and prevent the inner filter 100 from shaking.

[0310] In addition, when mounted on the mounting portion 178 , the external filter 200 may be disposed on the mounting portion 178 without shaking.

[0311] For example, the top surface of the seat body 210 of the external filter 200 may be configured to have a shape corresponding to the bottom surface of the support body 110 of the internal filter 100 or the bottom surface of the placement surface 113 of the support body 110. Thus, the seat body 210 may support the support body 110 by contacting the support body 110 or the placement surface 113.

[0312] In addition, the bottom surface of the seat body 210 is configured to have a shape corresponding to the top surface of the installation pipe 1782 and is placed in surface contact with the installation pipe 1782 .

[0313] Therefore, the seat body 210 can be fixed to the mounting portion 178 without shaking.

[0314] On the other hand, the outer peripheral cross section of the insert body 220 is configured to have a shape corresponding to the inner cross section of the mounting body 1782, and the insert body 220 can be supported in contact with the mounting body 1782. Therefore, when the insert body 220 is accommodated in the mounting body 1782, it can be fixed to the mounting body 1782 without shaking.

[0315] In addition, the inserting body 220 may be configured such that at least a portion of an inner surface is supported in surface contact with an outer surface of the receiving body 120 .

[0316] At least a portion of the inner surface of the inserting body 220 may be supported in surface contact with two surfaces (or front and rear surfaces) of the receiving body 120 .

[0317] Therefore, when the receiving body 120 is received in the inserting body 220 , it can be fixed without shaking.

[0318] For example, the inner circumferential cross section of the inserting body 220 may be configured to have a shape corresponding to the outer circumferential cross section of the containing body 120, and the area may also be configured accordingly. The containing body 120 may be independently fixed inside the inserting body 220 without being moved.

[0319] Thus, the outer filter 200 can maintain the state in which the inner filter 100 is fixed to the mounting portion 178 .

[0320] As a result, the internal filter 100 can be physically installed and fixed relative to the mounting portion 178 only when the external filter 200 is installed on the mounting portion 178, and the external filter 200 can be physically maintained in a state of being installed on the mounting portion 178 only when the internal filter 100 is installed on the mounting portion 178.

[0321] On the other hand, when the signal generating unit 300 is not provided on the internal filter 100 and the signal generating unit 300 is provided only on the external filter 200, since the operation state of the clothing processing device cannot be realized by the internal filter 100 alone, it can be guided that the external filter 200 must be installed on the installation part 178.

[0322] On the other hand, the coupling portion 160 of the internal filter 100, such as area A, includes a guide box 115, and the guide box 115 adjusts the coupling hook 1613 to be installed or loaded and unloaded on the mounting portion 178, and can also be configured as area B to selectively combine the mounting portion 178 and the coupling hook 1613.

[0323] Fig.11 2 is a diagram showing a specific embodiment of the coupling portion 160 .

[0324] The coupling portion 160 may include a coupling rib 161 that is configured to be reciprocally movable from the support body 110 to the inner surface of the installation groove 1781 .

[0325] The coupling hook 1613 may be formed at a distal end of the coupling rib 161 .

[0326] The support body 110 may include a movable rail 114 on an inner surface or an inner surface thereof, which is supported by the coupling rib 161 to reciprocate.

[0327] The movable rail 114 may be disposed to extend along a width direction of the support body 110 .

[0328] The coupling ribs 161 may be disposed in plurality on both sides of the support body so as to move back and forth toward the inner surface of the mounting groove. The coupling hooks 1613 may be formed at the ends of the plurality of coupling ribs 161 , respectively.

[0329] The plurality of coupling ribs 161 may be configured to move toward the side surfaces of the support body 110 based on the guide box 115 .

[0330] In other words, the coupling rib 161 disposed on one side of the guide box 115 can be reciprocated toward one side of the support body 110 , and the coupling rib 161 disposed on the other side of the guide box 115 can be reciprocated toward the other side of the support body 110 .

[0331] The mounting portion 178 may further include a coupling hole 1785 on the inner surface of the mounting hole 1781 , into which the coupling hook 1613 disposed at the end of the coupling rib 161 can be accommodated and coupled.

[0332] The coupling rib 161 moves toward the coupling hole 1785, and the coupling hook 1631 can be inserted into the coupling hole 1785 with a sufficient length. As a result, even if vibration or a temporary impact generated in the drum 2 or the like is applied to the coupling hook 1631, the coupling hook 1631 can be prevented from being separated from the coupling hole 1785. Therefore, the state in which the filter unit 10 is placed on the mounting portion 178 can be maintained, and the operation of the laundry processing device can be prevented from being accidentally interrupted.

[0333] In addition, the coupling rib 161 may also move to the guide box 115 to completely lead the coupling hook 1631 out of the coupling hole 1785. Thus, it is possible to prevent the mounting portion 178 from being damaged when the inner filter 100 is separated from the mounting portion 178.

[0334] The coupling portion 160 may further include an elastic member 162 disposed between the plurality of coupling ribs 161 and configured to push the plurality of coupling ribs toward two side surfaces of the support body.

[0335] The elastic member 162 may push the coupling rib 161 to allow the coupling hook 1613 to be inserted into the coupling hole 1785 , and may be configured to push the coupling rib 161 toward the guide box 115 .

[0336] When the coupling ribs 161 are drawn out of the coupling holes 1785 , the elastic member 162 may be compressed between the plurality of coupling ribs 161 to provide a force for pushing the coupling ribs 161 open again.

[0337] Therefore, when an external force is transmitted by a user, the coupling rib 161 presses the elastic member 162 while separating from the mounting portion 178. In addition, when the external force is released, the coupling rib 161 may move to the outside of the support body 110 again through the elastic member 162.

[0338] Specifically, the plurality of coupling ribs 161 may include: a pushing end 1611 coupled with the elastic member 162 ; and an extending rib 1612 extending from the bottom of the pushing end 1611 toward the two side surfaces of the support body 110 and having the coupling hook 1613 at the end.

[0339] The pushing portion 1611 is configured to be exposed to the guide box 115 for a user to apply pressure. The pushing portion 1611 may be configured to move back and forth on the guide box 115 , and may be configured to be exposed to two side surfaces of the guide box 115 .

[0340] The extension rib 1612 may be configured to extend from the bottom of the pushing end 1611 toward the side of the support body 110 .

[0341] The extension rib 1612 may move integrally with the pushing portion 1611 .

[0342] The elastic member 162 may be accommodated in the guide box 115 and disposed between the plurality of pushing portions 1611 .

[0343] The movable rail 114 may be configured to have a shape corresponding to the extension rib 1612 and support the extension rib 1612 in a slidable manner.

[0344] The coupling rib 161 is supported by the guide box 115 and the movable rail 114 to reciprocate.

[0345] The guide box 115 may be configured to support the top and the front or back of the pushing portion 1611 , and may be configured in a pipe shape with both sides opened to expose the side of the pushing portion 1611 .

[0346] The side surface of the pushing portion 1611 may be exposed through the opening 112 , and the blocking rib 111 is configured to be spaced apart from the guide box 115 by a certain distance, thereby ensuring a space for a user to press the side surface of the pushing portion 1611 .

[0347] The coupling ribs 161 may be configured to have the same length, and the guide box 115 may be disposed at the center of the support body 110. Thus, the user may apply the same force to move the plurality of coupling ribs 161.

[0348] When the coupling rib 161 is disposed in the coupling hole 1785 , the signal generating unit 300 disposed in the filter unit 10 is disposed at a height parallel to the detecting unit 400 coupled to the mounting unit 178 so as to overlap with each other.

[0349] When the coupling rib 161 is separated from the coupling hole 1785 , the filter unit 10 is drawn out from the mounting portion 178 by the restoring force of the elastic portion 260 , and the signal generating portion 300 may be disposed closer to the top than the detecting portion 400 .

[0350] The pushing portion 1611 , the extending end 1612 , and the coupling hook 1613 may be integrally configured and may be made of a resin series or the like.

[0351] The guide box 115 may provide a space for accommodating the elastic member 162 .

[0352] The plurality of coupling ribs 161 may be configured to be spaced apart by a certain length in the guide box 115, the length being the same as the lead-out length for completely leading or separating the coupling hook 1613 from the mounting groove. The elastic member 162 may be configured to be longer than the lead-out length, and the width of the guide box 115 may also be configured to be longer than the lead-out length.

[0353] When the coupling hook 1613 is inserted into the coupling hole 1785, the coupling rib 161 can continuously provide a force to pressurize the elastic part 260. That is, since the rigidity of the coupling rib 161 is greater than the elastic force provided by the elastic part 260, the elastic part 260 can be kept in a state of being fully pressurized.

[0354] Thus, the coupling portion 160 may maintain a state in which the external filter 200 is mounted to the mounting portion 178 .

[0355] Fig.12 2 is a diagram showing the operation mode of the coupling rib.

[0356] The coupling ribs 161 are configured in plural numbers and may be supported by the guide box 115 and the moving rail 114 .

[0357] In the guide box 115 , the pusher 1611 of the coupling rib 161 is supported to be reciprocally movable in the width direction.

[0358] The plurality of coupling ribs 161 may be spaced apart from each other by a length greater than the lead-out length.

[0359] The pushing parts 1611 respectively arranged on the coupling ribs 161 may also be arranged to be reciprocally movable and drawn out from the guide box 115 .

[0360] Reference Fig.12 (a), the pusher 1611 may be configured as a box shape with one side open to accommodate at least a portion of the elastic member 162. The pusher 1611 may include a fixing protrusion 1611d to fix the position of the elastic member 162.

[0361] The pushing portion 1611 may include: a connecting surface 1611c extending from or combined with the extension rib 1612; a pressurizing surface 1611b extending from the connecting surface 1611c and providing a pressurized space to the user and provided with the fixing protrusion 1611d; and an extending surface 1611a extending from the pressurizing surface 1611b and supported by the guide box 115.

[0362] The open surfaces disposed opposite to the pressurizing surface 1611 b and accommodating the elastic member 162 may be disposed to be opposite to each other at the plurality of pushing portions 1611 .

[0363] The extension rib 1612 and the inner surface of the pushing portion 1611 may be configured to be spaced apart from each other by a length that is more than twice the lead-out length.

[0364] This is because the one extension rib 1612 also moves more than the lead-out length to be separated from the coupling hole 1785. Therefore, the extension rib 1612 on the left side can also move more than the lead-out length to the right side, and the extension rib 1612 on the right side can also move more than the lead-out length to the left side.

[0365] Reference Fig.12 (a), when the user applies pressure to the pressurizing surface 1611b exposed on both sides of the guide box 115, the pusher 1611 on the left side and the pusher 1611 on the right side approach each other. Thus, the plurality of extension ribs 1612 can approach each other, and the coupling hook 1613 can be drawn out from the coupling hole 1785.

[0366] The elastic portion 1612 is compressed by the plurality of pushing portions 1611 approaching each other.

[0367] The elastic portion 1612 may be configured to push the pushing portion 1611 away when the external force applied to the pressurizing surface 1611 b is released.

[0368] Therefore, the coupling portion 160 can be operated without a separate electronic control. The user can selectively press the pressurizing surfaces 1611 b on both sides of the guide box 115 exposed in the pushing portion 1611 to install the internal filter 100 on or separate it from the installation portion 178 .

[0369] In addition, the inner filter 100 may be completely installed in or released from the outer filter 200 through the coupling portion 160 .

[0370] In addition to the above-mentioned physical method, the clothes processing device of the present invention can also guide the internal filter 100 and the external filter 200 to be combined at the same time through an electronic control method.

[0371] For example, the clothes treating apparatus of the present invention may be configured such that the clothes treating apparatus does not operate when the internal filter 100 and the external filter 200 are not installed on the installation portion 178 at the same time.

[0372] As described above, a signal generating unit 300 generating a signal is provided on any one of the internal filter 100, the external filter 200 and the mounting portion 178, and the mounting portion 178 may include a detection unit 400 for detecting whether the filter portion 10 is installed by detecting the signal generating unit 300.

[0373] The signal generating unit 300 may be configured to reciprocate along a surface of any one of the mounting unit, the external filter, and the internal filter. The signal generating unit 300 may change its position in a sliding manner to overlap with or be completely separated from the detecting unit 400 .

[0374] Therefore, the detection unit 400 can more reliably detect the position change of the signal generation unit 300, and thus can more accurately detect whether the filter unit 10 is installed.

[0375] In addition, when the signal generating unit 300 moves in a height direction or in an insertion and extraction direction of the filter unit 10 , the signal generating unit 300 may move in contact with the filter unit 10 without hindering the insertion or extraction of the filter unit 10 .

[0376] The signal generating unit 300 may be configured to move toward the detecting unit 400 when the external filter 100 or the internal filter 200 is installed in the mounting unit 178. In addition, the signal generating unit 300 may be configured to move without overlapping with the detecting unit 400 when the external filter 100 or the internal filter 200 is drawn out from the mounting unit 178.

[0377] As a result, the reliability and responsiveness of the signal generating unit 300 can be ensured.

[0378] Reference Figures 13 to 18 When the signal generating unit 300 is in the state of being moved back and forth, the signal generating unit 300 may include: a magnet 320 generating a magnetic field; a guide rail 310 providing a space in which the magnet 320 can move back and forth; and a restoring unit 330 provided on the guide rail 310 to support the magnet 320 .

[0379] The guide rail 310 may be configured to extend from a position overlapping with the detection portion 400 to a position not overlapping with the detection portion 400 .

[0380] For example, the guide rail 310 may be configured such that one end thereof is located at a position overlapping with the detection unit 400 , and the other end thereof is located at a position not overlapping with the detection unit 400 .

[0381] The magnet 320 may be accommodated in the guide rail 310 so as to reciprocate from one end to the other end of the guide rail 310 .

[0382] The magnet 320 is located at a position not overlapping with the detection unit 400 on the guide rail 310 , and then moves to a position overlapping with the detection unit 400 through the filter unit 10 .

[0383] The restoring portion 330 may be configured to be received in the guide rail 310 and to push the magnet 320 to a position not overlapping with the detection portion 400. The restoring portion 330 may be made of an elastic material such as a spring.

[0384] The detection portion 400 may be configured to overlap a specific area of ​​the guide rail 310 on an outer surface of the mounting pipe 1782 .

[0385] Of course, as long as the detection unit 400 does not hinder the movement of the filter unit 10 , the detection unit 400 can be disposed on the inner surface of the installation pipe 1782 .

[0386] Fig.13 It is a diagram showing an embodiment of a signal generating unit and a detecting unit of a clothes processing device of the present invention.

[0387] The signal generating unit 300 and the detecting unit 400 may both be disposed on the mounting portion 178 .

[0388] The signal generating unit 300 is disposed on the inner peripheral surface of the mounting portion 178 , and is movably disposed toward the detecting unit 400 via the external filter 200 .

[0389] In the signal generating unit 300 , the guide rail 310 may be disposed in the mounting pipe 1782 , exposed inside the mounting pipe 1782 , and protruded outside the mounting pipe 1782 .

[0390] The guide rail 310 may be configured to extend from the top surface to the bottom of the mounting pipe 1782 , and may be configured closer to the bottom than the seat body 210 when the seat body 210 is supported by the mounting pipe 1782 .

[0391] When the outer filter 200 is coupled, the magnet 320 is configured to come into contact with the outer filter 200 and move toward the bottom of the guide rail 310 .

[0392] Thus, by simultaneously providing the signal generating unit and the detecting unit on the mounting portion 178 , the filter unit 10 can be manufactured relatively simply, and the filter unit 10 can also be easily repaired and replaced.

[0393] Fig.14 The diagram shows Fig.13 A diagram showing the operation modes of the signal generating unit and the detecting unit.

[0394] Fig.14 (a) is a perspective view showing a cross section of the external filter 200 starting to be installed on the installation portion 178, Fig.14 (a) shows the cross section from the front.

[0395] The guide rail 310 may be configured in a pipe shape so that the magnet 320 can be exposed inside the mounting pipe 1782 .

[0396] The guide rail 310 may be configured to extend toward the bottom closer to the bottom than the support surface 1783 .

[0397] A portion of the magnet 320 is configured to be accommodated in the guide rail 310 , and another portion is configured to protrude from the guide rail 310 toward the inside of the mounting pipe 1782 , so as to be contactable with either the seat body 210 or the insert body 220 .

[0398] The restoration portion 330 may be configured to be supported by the inner bottom surface of the guide rail 310 and to push the magnet 320 toward the top.

[0399] The detection portion 400 may be configured to overlap with the guide rail 310 outside the guide rail 310 and to be close to the bottom of the guide rail 310 .

[0400] The detection unit 400 may be disposed at a position to be opposite to the magnet 320 when the external filter 200 is installed and the external filter 200 pressurizes the magnet 320 .

[0401] The detection unit 400 may be disposed outside the installation pipe 1782 .

[0402] The external filter 200 may be configured to pressurize the magnet 320 when inserted into the mounting conduit 1782 .

[0403] For example, it may be configured that the bottom surface of the seat body 210 can pressurize the magnet 320. Of course, other structures of the external filter 200 such as the insert body 220 can also pressurize the magnet 320.

[0404] Thus, when the external filter 200 is inserted into the installation pipe 1782 until the mounting platform 250 is mounted to the top surface of the installation pipe 1782 , the bottom surface of the seat body 210 can move the magnet 320 toward the bottom to overlap with the detection portion 400 .

[0405] Therefore, the detection unit 400 can detect whether the external filter 200 is completely installed in the installation portion 178 by detecting the magnet 320 .

[0406] At this time, when the elastic portion 260 is disposed on the external filter 200 , the elastic portion 260 pushes the external filter 200 toward the top. Since the external filter 200 cannot continue to pressurize the magnet 320 , the magnet 320 can rise toward the top through the restoring portion 330 .

[0407] Therefore, the detection unit 400 cannot detect the magnet 320 , and the control unit may recognize that the external filter 200 is not completely installed in the installation portion 178 .

[0408] In addition, since the external filter 200 can be installed only when the internal filter 100 is completely installed in the installation portion 178, the control portion can detect through a signal generating portion 300 whether the detection portion 400 installs the internal filter 100 and the external filter 200 at the same time.

[0409] As a result, the control unit may recognize that at least one of the inner filter 100 and the outer filter 200 is not installed on the installation portion 178 only because the detection unit 400 cannot detect the magnet 320, and may not allow the laundry treating apparatus to operate.

[0410] As a result, the user can be guided to install both the internal filter 100 and the external filter 200 on the installation portion 178 .

[0411] Fig.15 It is a diagram showing another embodiment of the signal generating unit and the detecting unit.

[0412] The signal generating unit 300 may be provided in the external filter 200 .

[0413] The signal generating unit 300 may be disposed on the inner surface of the outer filter 200 so as to be movable toward the bottom through the inner filter 100 .

[0414] The detection unit 400 may be provided at the mounting portion 178. The detection unit 400 may be provided at a position capable of detecting the signal generating unit 300 when the outer filter 200 is completely mounted on the mounting portion 178 and the inner filter 100 is mounted on the outer filter 200.

[0415] Specifically, the signal generating unit 300 may be disposed inside the external filter 200 .

[0416] The guide rail 310 may be disposed on the inner surface of the inserting body 220 and the magnet 320 may be exposed inside the inserting body 220. The guide rail 310 may be disposed on the inner surface of the inserting body 220 to extend in the up-down direction.

[0417] When the inserting body 220 can be divided into two, the guide rail 310 is only combined with one of the inserting bodies 220, so as not to hinder the inserting body 220 from being separated and recombined.

[0418] The magnet 320 may be configured such that at least a portion of the magnet 320 is accommodated in the guide rail 310 and moves up and down along the guide rail 310 .

[0419] The restoration portion 330 may be configured to be coupled to an inner bottom surface of the guide rail 310 and push the magnet 320 toward the top.

[0420] The magnet 320 may be configured to at least partially protrude from the guide rail 310 to be able to contact the inner filter 100. The guide rail 310 may be configured to have a slit shape supporting both surfaces of the magnet 320, and may further have a step to prevent the magnet 320 from detaching to the outside.

[0421] Thus, when the inner filter 100 is accommodated in the outer filter 200 , the inner filter 100 may move the magnet 320 toward the bottom of the guide rail 310 .

[0422] At this time, when the outer filter 200 is mounted on the mounting portion 178 in a state of accommodating the inner filter 100 , the magnet 320 may be disposed at a position overlapping with the detection portion 400 .

[0423] Thus, the detection unit can detect the magnet 320 , and the control unit can recognize that the internal filter 100 and the external filter 200 are simultaneously coupled to the mounting portion 178 .

[0424] However, when the outer filter 200 is mounted to the mounting portion 178 without accommodating the inner filter 100, the guide rail 310 moves toward the top and the magnet 320 does not overlap the detection portion 400. In addition, when only the inner filter 100 is mounted on the mounting portion 178, the detection portion 400 cannot detect the magnet 320.

[0425] Therefore, the control unit can recognize that at least one of the internal filter 100 and the external filter 200 is not installed on the installation portion 178 only when the detection unit 400 cannot detect the magnet 320, and thus may not allow the laundry treating apparatus to operate.

[0426] As a result, the user can be guided to install both the internal filter 100 and the external filter 200 in the installation portion 178 .

[0427] Fig.16 It is shown Fig.15 FIG. 1 is a diagram of a structure in which the inner filter 100 causes the magnet 320 to move toward the bottom.

[0428] The inner filter 100 may be configured to pressurize the magnet 320 while being received in the outer filter 200 .

[0429] The inner filter 100 may include a top protrusion 125 on an outer surface thereof, and the top protrusion 125 may protrude to push the magnet 320 in the signal generating part 300 toward the bottom.

[0430] For example, the receiving body 120 may be configured to pressurize the magnet 320 .

[0431] The top protrusion 125 may be configured such that an outer surface of the receiving body 120 contacts the magnet 320 .

[0432] The top protrusion 125 can be configured to at least partially contact the magnet 310 during the process of inserting the internal filter 100 into the external filter 200, and when the internal filter 100 is fully accommodated in the external filter 200, be configured to be in a position that allows the magnet 310 to descend to the maximum extent.

[0433] The top protrusion 125 protrudes outward from the side of the receiving body 120 so as not to hinder the receiving body 120 from being received in the external filter 200 .

[0434] When the top protrusion 125 presses the magnet 320 , the restoration portion 330 may be compressed.

[0435] In this state, when the external filter 200 is mounted on the mounting portion 178 , the magnet 320 may be configured to overlap with the detection portion 400 .

[0436] Fig.17 It is a diagram showing another embodiment of the signal generating unit and the detecting unit.

[0437] The signal generating unit 300 may be provided in the internal filter 100 .

[0438] The signal generating unit 300 is disposed on the outer surface of the inner filter 100 so as to move toward the top through the outer filter 200 .

[0439] The detection unit 400 may be provided at the mounting portion 178. The detection unit 400 may be provided at a position where the signal generating unit 300 can be detected when the outer filter 200 is completely mounted on the mounting portion 178 and the inner filter 100 is mounted on the outer filter 200.

[0440] Specifically, the signal generating unit 300 may be disposed outside the internal filter 100 .

[0441] The guide rail 310 may be disposed on the outer surface of the container 120 and the magnet 320 may be exposed to the outside of the container 120. The guide rail 310 may be disposed on the outer surface of the container 120 to extend in the up-down direction.

[0442] When the receiving body 120 can be divided into two, the guide rail 310 is only combined with one of the receiving bodies 120 without preventing the receiving bodies 120 from being separated and recombined.

[0443] The magnet 320 may be configured to be at least partially accommodated in the guide rail 310 and move up and down along the guide rail 310 .

[0444] The restoration portion 330 may be configured to be coupled to an inner top surface of the guide rail 310 and push the magnet 320 toward the bottom.

[0445] The magnet 320 may be configured to protrude at least partially from the guide rail 310 to contact the external filter 200. The guide rail 310 may be configured in a slit shape supporting both surfaces of the magnet 320, and may further have a step so that the magnet 320 does not fall out to the outside.

[0446] Thus, when the inner filter 100 is accommodated in the outer filter 200 , the outer filter 200 can move the magnet 320 toward the top of the guide rail 310 .

[0447] When the outer filter 200 is mounted on the mounting portion 178 in a state of accommodating the inner filter 100 , the magnet 320 may be disposed at a position overlapping with the detection portion 400 .

[0448] Thus, the detection unit can detect the magnet 320 , and the control unit can recognize that the internal filter 100 and the external filter 200 are simultaneously coupled to the mounting portion 178 .

[0449] However, when the outer filter 200 is mounted on the mounting portion 178 without accommodating the inner filter 100 , the detector 400 cannot detect the magnet 320 .

[0450] In addition, when only the inner filter 100 is mounted on the mounting portion 178 , the magnet 320 does not move toward the top and does not overlap with the detection portion 400 .

[0451] Therefore, the control unit can recognize that at least one of the internal filter 100 and the external filter 200 is not installed on the installation portion 178 only when the detection unit 400 cannot detect the magnet 320, and may not allow the laundry processing apparatus to operate.

[0452] As a result, the user can be guided to install both the internal filter 100 and the external filter 200 in the installation portion 178 .

[0453] Fig.18It is shown Fig.17 FIG. 2 is a diagram of a structure in which the outer filter 200 moves the magnet 320 toward the bottom.

[0454] The outer filter 200 may be configured to pressurize the magnet 320 during the process of accommodating the inner filter 100 .

[0455] For example, the insert 220 may be configured to pressurize the magnet 320 .

[0456] The outer filter 200 may include a bottom protrusion 225 on the inner surface thereof so as to push the magnet 320 of the signal generating unit 300 toward the top.

[0457] The insert 220 may further include a bottom protrusion 225 on an inner surface thereof and configured to contact the magnet 320 .

[0458] The bottom protrusion 225 is configured to at least partially contact the magnet 310 during the process of inserting the internal filter 100 into the external filter 200, and can be configured to a position that allows the magnet 310 to rise to the maximum when the internal filter 100 is fully accommodated in the external filter 200.

[0459] The bottom protrusion 225 may be configured to protrude inwardly from the side of the insert body 220 but not to contact the inner filter 100 . Thus, the inner filter 100 may be prevented from being accommodated in the outer filter 200 .

[0460] The restoring portion 330 may be compressed when the bottom protrusion 225 presses the magnet 320 .

[0461] In this state, when the external filter 200 is mounted on the mounting portion 178 , the magnet 320 may be configured to overlap with the detection portion 400 .

[0462] The utility model can be implemented in various forms, and its scope of rights is not limited to the above-mentioned embodiments. Therefore, as long as the modified embodiments include the constituent elements of the scope of the claims of the utility model, they can be regarded as belonging to the scope of rights of the utility model.
