Description

Garment processing equipment

[0001] The present invention relates to a clothing treatment device. More specifically, it relates to a commercial dryer capable of performing drying processes, such as sterilizing, removing wrinkles, deodorizing, and drying, on clothing by supplying steam or hot air to the clothing.

[0002] In general, a garment treatment device performs any course of treating garments, and may include a dryer that performs a drying process.

[0003] In the case of commercial dryers, bulky and heavy clothes such as bedding can be loaded in a wet state compared to household dryers, and they can be equipped to perform more drying cycles to dry a large quantity of clothes.

[0004] Accordingly, commercial dryers need to be designed to be much larger in volume and to supply a greater amount of hot air than household dryers, so that they can quickly dry a large amount of clothes.

[0005] Figure 1 illustrates the basic structure of a conventional commercial dryer.

[0006] A conventional commercial dryer may include a drum (1) for accommodating clothes, a support plate (2) for rotatably supporting the drum (1) from the front and rear, and a circulation duct (4) that connects the support plates (2) to each other and is positioned lower than the drum (1).

[0007] The above support plate (2) may be provided with an internal duct (3) that connects the inside of the drum (1) and the circulation duct (4) at the front, and the circulation duct (4) has a built-in heat exchanger that dehumidifies or heats the air discharged from the drum (1) to the internal duct (3).

[0008] However, the support plate (2) needed to be manufactured with a somewhat complex shape in order to support the drum (1) while including the internal duct (3), etc., so that it could rotate. Accordingly, in conventional commercial dryers, the support plate (2) was generally manufactured with a resin-based material rather than a metal material, which is very difficult to process due to its complex structure.

[0009] However, since commercial dryers load heavy and large-volume clothes, such as bedding, into the drum (1) while they are wet, the overall weight of the drum (1) inevitably becomes very heavy. In addition, when the drum (1) rotates, the amount of impact or vibration energy generated from the drum (1) can be much greater than that of a typical household dryer.

[0010] In this state, it was difficult to rotatably support the heavy drum (1) with a support plate (2) made of resin, such as that of the commercial dryer, and there was a fundamental problem that the support force of the support device such as the roller could not be guaranteed, and the rigidity or durability of the support plate (2) itself could not be guaranteed.

[0011] Furthermore, in the case of commercial dryers, the drum (1) needs to be longer than that of household dryers in order to accommodate a large amount of clothing. In this case, the duct (3) provided in a portion of the support plate (2) cannot handle the flow rate discharged from the drum (1), and due to limitations in the installation area, there is a fundamental problem in that the thickness of the support plate (2) cannot be forcibly expanded to secure the area of ​​the duct (3).

[0012] Figure 2 illustrates a recently introduced commercial dryer.

[0013] Recently, in order to solve the problem of the commercial dryer of Fig. 1, a commercial dryer has appeared in which the drum (1) has a discharge hole through which hot air is discharged on the outer surface.

[0014] The above commercial dryer further includes a housing (5) that accommodates all of the discharge holes of the drum (1) inside the cabinet (2) and guides the movement of air.

[0015] The housing (5) above was made entirely of metal and could sufficiently support vibrations and impacts generated from the drum (1). As a result, a support member or the like that directly supports the drum (1) so that it can rotate could be installed inside the housing (5). Since the housing (5) could rotate the drum (1), the support plate (2) or the like that was positioned in front of the drum (1) could be omitted.

[0016] Furthermore, the housing (5) is provided to receive the outer surface of the drum (1) and communicate with the duct module (8) arranged below, so that the hot air supplied to the drum (1) can be smoothly discharged through the side of the drum (1) and the housing (5) even if it is not completely discharged to the front of the drum (1). Accordingly, since the drum (1) and the housing (5) function as a duct through which the hot air flows, there is an advantage in that sufficient hot air can flow even if the volume of the drum (1) is large and a large amount of clothing is put in.

[0017] However, in these commercial dryers, the drive unit (6) that rotates the drum (1) was generally placed lower than the drum (1). Since the drive unit (6) is heavier than that of a household dryer in order to rotate a large-capacity drum (1), it was necessary to install the drive unit (6) in a duct module (8) to ensure stability.

[0018] As a result, there was a problem that the rear outer surface of the drum (1), which is positioned vertically above the driving unit (6), had to be exposed as it was in order to avoid interference with the belt connecting the driving unit (6) and the drum (1). Furthermore, since it was difficult to narrow the gap between the driving unit (6) and the drum (1), there was a problem that it was impossible to design the housing (5) to accommodate the space through which the belt passed.

[0019] Accordingly, there was a problem in that it was difficult to ensure sealing between the drum (1) and the rear panel (2a) of the cabinet (2), and it was also difficult to ensure sealing between the inner surface of the housing (5) and the outer surface of the drum (1).

[0020] In particular, since the housing (5) of the commercial dryer cannot help but be separated from the rear panel (2a), it was essential to install a sealing member or the like on the rear inner surface of the housing (5) and the outer surface of the drum (1) to prevent hot air from randomly leaking rearward from the area where the exhaust hole is formed on the outer surface of the drum (1). Since the drum (1) vibrates not only up and down but also forward and backward while rotating, it was common for a sealing member to be coupled to the outer surface of the drum (1) to ensure sealing performance. As a result, there was a limitation in that the sealing member could not guarantee sealing performance with the housing (5) because it was coupled to the vibrating drum (1).

[0021] As a result, the conventional commercial dryer had a structure in which there was a high possibility that the hot air supplied to the drum (1) would leak out, and thus had a limitation in that it could not help but suffer losses in drying performance.

[0022] Furthermore, since the housing (5) is designed to avoid the driving unit (6), there was a limitation that it was fundamentally impossible to install the driving unit (6) in the housing (5).

[0023] The present invention aims to provide a clothing treatment device capable of preventing the leakage of hot air supplied to a drum and circulating the same.

[0024] The present invention aims to provide a garment treatment device having a separate housing that completely accommodates a drum and guides hot air supplied to the drum.

[0025] The present invention aims to provide a garment treatment device capable of securing sealing performance by installing a sealing member that prevents leakage of hot air passing through a drum in a fixed configuration without rotating.

[0026] The present invention aims to provide a garment treatment device capable of reducing the area through which a belt passes in a housing by minimizing the gap between a drum and a driving unit.

[0027] The present invention aims to provide a garment treatment device in which a driving unit can be mounted in a housing that accommodates a drum.

[0028] The present invention provides a garment treatment device including a housing capable of guiding hot air supplied to the drum from the rear to the front of the drum while completely accommodating the drum.

[0029] The above housing is provided with a duct extending from the rear to the front of the cabinet in which the drum is installed, so as to seal the cabinet separately from the drum.

[0030] The above housing is provided to seal between the cabinets, thereby preventing hot air from leaking out of the cabinet.

[0031] The sealing portion that is combined to seal between the housing and the cabinet is arranged on the outside of the drum, spaced apart from the drum, and combined with a fixed configuration such as the housing and the cabinet to ensure sealing performance.

[0034] The cabinet may include a front panel in which the opening is formed, and a rear panel disposed at the front of the case and communicating with the duct-forming portion.

[0035] The housing may be provided to extend from the front panel to the rear panel, and the sealing portion may be disposed between the front panel and the housing.

[0036] The housing is provided so that the front surface facing the front panel is open, and the sealing portion can be fixed by being joined along the perimeter of the front surface of the housing.

[0037] The above sealing portion may be provided as an elastic member that is coupled to the front surface of the housing and pressurized against the inner surface of the front panel.

[0038] The above sealing portion may include a sealing body coupled along the entire perimeter of the front surface of the housing.

[0039] The housing may be provided with a different shape from the drum, and the sealing body may be provided with a different shape from the drum.

[0040] The above sealing body may be placed outside the outer surface of the drum.

[0041] The above-mentioned drying body further includes a support member that is mounted on the housing and rotatably supports the drum, and the sealing body can be arranged outside the support member.

[0042] The above-mentioned drying body further includes a door for opening and closing the opening, and a hinged portion fixed to the housing and supporting the door, and the sealing body may be arranged outside the hinged portion.

[0043] The above sealing body may be provided to protrude further forward than the hinge joint in the housing and press against the inner surface of the front panel.

[0044] The above-mentioned drying body further includes a control panel coupled to the front panel to display a status externally or receive a command from a user, and the control panel may be positioned outside the sealing body.

[0045] In order to solve the above-described problem, the present invention provides a clothes treatment device including a housing that is arranged inside the cabinet to accommodate the drum and is arranged in front of the duct-forming part to form a duct that guides the air to the duct body.

[0046] The rear of the above housing may be positioned further rearward than the back surface of the above drum.

[0047] The cabinet may include a front panel in which the opening is formed, and a rear panel disposed at the front of the case and communicating with the duct-forming portion.

[0048] The housing may be provided to accommodate the drum by extending from a front portion of the drum to the front portion of the rear panel.

[0049] The above housing can be formed with a front surface facing the front panel open.

[0050] The clothing treatment device of the present invention further includes a door for opening and closing the opening, and the door can be rotatably supported on both sides of the housing.

[0051] The above-mentioned drying body may further include a hinged portion that is coupled to the inner surface of the housing, faces at least a portion of the drum, and rotatably fixes the door.

[0052] The above drying body further includes a support member that rotatably supports the drum inside the cabinet, and the support member can be placed inside the housing.

[0053] The support member may include a roller that is mounted on the bottom surface of the housing and supports the lower portion of the drum.

[0054] The above housing may be provided with a shape different from the shape of the drum.

[0055] The housing may include a bottom surface that is positioned at the bottom of the drum and supported by the duct body, side plates that extend from both sides of the bottom surface to face both sides of the drum and connect the front panel and the rear panel, and an upper plate that extends upward from the side plate to accommodate the drum.

[0056] The cabinet further includes an upper panel extending from the front panel to the rear panel at the upper portion of the housing, and the upper plate can be disposed spaced downward from the upper panel.

[0057] The above drying body includes a driving unit that is mounted on the housing and rotates the drum, and the driving unit can be mounted on the upper plate.

[0093] Hereinafter, embodiments disclosed in this specification will be described in detail with reference to the attached drawings. In this specification, identical or similar components are given identical or similar reference numerals even in different embodiments, and the description thereof is replaced with the first description. The singular expression used in this specification includes plural expressions unless the context clearly indicates otherwise. In addition, when describing the embodiments disclosed in this specification, if a detailed description of a related known technology is judged to obscure the gist of the embodiments disclosed in this specification, the detailed description thereof will be omitted. In addition, it should be noted that the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification should not be construed as being limited by the attached drawings.

[0094] Figure 3 illustrates one embodiment of the clothing treatment device of the present invention.

[0095] The clothing treatment device of the present invention may be equipped with a dryer capable of performing any drying course to remove moisture from clothing.

[0096] The clothing treatment device of the present invention may include a drying body (10) capable of accommodating clothing, a drying module (20) capable of supplying at least one of heated air (hot air) and steam to the drying body (10), and a duct module (30) providing a path through which air inside the drying body (10) can be discharged to the drying module (20) or the outside.

[0097] The garment treatment device of the present invention can be installed as a commercial dryer. Accordingly, the garment treatment device of the present invention can be deployed in environments where multiple users repeatedly perform the drying cycle, or where a large quantity of clothing, such as blankets or bedding, must be dried, compared to a household dryer. Therefore, the garment treatment device of the present invention must be equipped to accommodate a larger volume of clothing than a household dryer, and must be equipped to supply more hot air than a household dryer to quickly perform the drying cycle.

[0098] To this end, the clothes treatment device of the present invention needs to have a larger volume of the drying body (10) than a configuration for accommodating clothes in a home dryer, the drying module (20) needs to have a larger volume than the drying module of a home dryer in order to generate a large amount of hot air, and the duct module (30) needs to be larger than the duct module of a home dryer in order to allow a sufficient amount of air to move.

[0099] Accordingly, the clothing treatment device of the present invention may be provided such that at least one of the drying module (20) and the duct module (30) is disposed as a separate configuration from the drying main body (10) and is detachably coupled to the drying main body (10).

[0100] As a result, the clothing treatment device of the present invention can sufficiently expand the volume of the drying body (10) without being restricted by the installation space of the drying module (20) or the duct module (30). As a result, the drying body (10) can be equipped to accommodate a large amount of clothing without difficulty.

[0101] In addition, the clothing treatment device of the present invention can sufficiently expand the volume of the drying module (20) without being restricted by the installation space of the drying main body (10) or the duct module (30). Accordingly, the drying module (20) can also increase the volume of the heat supply unit that heats air or generates steam, so that it can be equipped to generate sufficient hot air to dry a large amount of clothing or sufficient steam to sterilize and disinfect a large amount of clothing.

[0102] In addition, the clothing treatment device of the present invention can sufficiently expand the volume of the duct module (30) without being restricted by the installation space of the drying main body (10) or the drying module (20). Accordingly, the duct module (30) can secure a path for a sufficient amount of air to move to the expanded drying main body (10) and the drying module (20), and a large-capacity filter described later can also be stably installed.

[0103] When the above drying body (10) is provided with an opening through which clothes are put in, the drying module (20) and the duct module (30) may be provided to communicate with the drying body (10) at a position that does not interfere with the opening.

[0104] When the opening of the above drying body (10) is arranged at the front, the drying module (20) may be arranged at any one of the upper, lower, both sides, and rear of the drying body (10), and the duct module (30) may be arranged at any one of the upper, lower, both sides, and rear of the drying body (10) at a position that does not interfere with the drying module (20).

[0105] For example, the clothing treatment device of the present invention can place the drying module (20) at the rear of the drying main body (10).

[0106] Accordingly, the volume of the drying module (20) can be expanded to a greater extent than when the drying module (20) is arranged at the upper and lower portions of the drying body (10), thereby maximizing the heating or heat exchange performance. In addition, since the drying module (20) is arranged at the rear of the drying body (10) rather than being provided at the side of the drying body (10), the overall width of the clothing treatment device of the present invention can be reduced, and a plurality of clothing treatment devices of the present invention can be easily arranged in a limited space. In addition, since the drying module (20) is arranged at the rear of the drying body (10), the flow path direction in which the hot air is discharged can be aligned with the flow path direction inside the drying body (10), thereby reducing the overall flow resistance.

[0107] Meanwhile, the duct module (30) may be placed on either the upper or lower side of the drying body (10). This allows the overall width of the garment treatment device of the present invention to be reduced compared to when it is placed on the side of the drying body (10).

[0108] The above duct module (30) can be placed at the bottom of the drying body (10). As a result, the clothing treatment device of the present invention can position the opening of the drying body (10) higher from the ground, and the user can easily take in and take out a large amount of clothing through the opening.

[0109] Of course, the clothing treatment device of the present invention may be provided in the form of a household dryer, with the duct module (30) installed inside the cabinet (10) and the drying module (20) installed inside the duct module (30). The following description will be based on the garment treatment device of the present invention being provided in the illustrated form, but the features of the configuration specified in the description may also be applied when provided with a household dryer.

[0110] Figure 4 illustrates an embodiment in which the configuration of the garment treatment device of the present invention is provided in a detachable manner.

[0111] The clothing treatment device of the present invention may be manufactured such that at least one of the drying main body (10), drying module (20), and duct module (30) is separated from the other and detachably coupled to allow air to flow through.

[0112] In general, the drying module (20) is equipped with heavy components for heating air or supplying steam, and may be relatively heavier than the drying main body (10) or duct module (30). In addition, the drying module (20) may have more electrical components than the internal components of the drying main body (10) and duct module (30), and thus may require more frequent maintenance.

[0113] To this end, the clothing treatment device of the present invention can be designed so that the drying module (20) can be detachably attached to the drying main body (10). Accordingly, the drying module (20) can be transported separately from the drying main body (10) to easily install the clothing treatment device of the present invention, and if there is a problem with the electrical components of the drying module (20), it can be replaced separately from the drying main body (10), and some parts of the drying module (20) can be replaced by separating it from the bulky drying main body (10), thereby facilitating maintenance work.

[0114] Meanwhile, the clothing treatment device of the present invention may be provided with the drying main body (10) and the duct module (30) as an integral unit. As a result, the connection between the drying main body (10) and the duct module (30) is strengthened, thereby preventing the possibility of air discharged from the drying main body (10) leaking to the outside.

[0115] In addition, even if strong vibration occurs in the drying body (10) due to the movement of a large amount of clothing, the drying body (10) can be prevented from being arbitrarily separated from the duct module (30). The drying body (10) and the duct module (30) can be placed inside a single cabinet and manufactured and transported simultaneously.

[0116] This is only an example, and the above-mentioned drying body (10) and the above-mentioned duct module (30) may be provided as separate modules and may be provided so as to be detachable from each other.

[0117] Figure 5 illustrates an embodiment of the internal structure of the clothing treatment device of the present invention.

[0118] The clothing treatment device of the present invention is equipped with an exhaust type, and the drying module (20) and the drying main body (10) are arranged to communicate with each other, and the drying main body (10) and the duct module (30) are arranged to communicate with each other. However, the drying module (20) and the duct module (30) may be arranged so as not to communicate with each other.

[0119] As illustrated, when the garment treatment device of the present invention is arranged in a circulating manner, the drying body (10), the duct module (30), and the drying module (20) can be arranged so that air flows through them. Accordingly, the garment treatment device of the present invention can be installed without difficulty, regardless of whether the indoor space is connected to the outdoors, as long as the installation space is secured.

[0120] The above drying body (10) may include a cabinet (110) that forms an exterior and has an opening, a door (120) that opens and closes the opening, and a drum (150) that is rotatably provided inside the cabinet (110) and receives clothes inserted through the opening.

[0121] The garment treatment device of the present invention may include a driving unit (160) that rotates the drum (150). Accordingly, garments accommodated in the drum (150) may be exposed to hot air supplied to the drum (150) and dried while rising and falling within the drum (150) due to the rotation of the drum (150).

[0122] The above driving unit (160) can be placed in the drying body (10).

[0123] Accordingly, the drum (150) and all components that rotate the drum (150) can be installed in the drying body (10) itself, and can be maintained independently of the components of the duct module (30) or the drying module (20). In addition, since the entire configuration of the driving unit (160) is installed independently of the duct module (30), the duct module (30) omits a configuration for the driving unit (160) to pass through or be installed, so that the sealing performance of the duct module (30) can be enhanced.

[0124] The above duct module (30) may include a duct body (310) positioned lower than the drum (150) to receive air discharged from the drum (150), a circulation fan (330) positioned at the rear of the duct body (310) to move the air, and a fan receiving portion (320) that provides a space in which the circulation fan (330) is installed.

[0125] The above duct body (310) may be provided so that the outer surface is completely sealed to prevent air from leaking to the outside, except for air flowing in from the drum (150).

[0126] The above duct body (310) may be provided in any shape as long as it is provided so that air discharged from the drum (150) can be introduced at the top and the air can be delivered to the rear.

[0127] For example, the duct body (310) may be provided in the shape of a case that is positioned at the bottom of the cabinet (110) to support the cabinet (110) and is shielded on all sides.

[0128] Alternatively, the duct body (310) may include at least one of a frame, such as a rectangular parallelepiped, which is placed inside the cabinet (110) and supports the components inside the cabinet (110), and a plate coupled to the frame.

[0129]

[0130] For example, the drying body (10) and the duct module (30) may be installed in one cabinet (110). The drying body (10) and the duct module (30) may be provided to share one cabinet (110). The drying body (10) and the duct module (30) may be installed inside the cabinet (110) forming the exterior, or the duct module (30) may be installed at the bottom of the drying body (10) after the drying body (10) is manufactured. This can prevent hot air or steam from leaking between the drying body (10) and the duct module (30), facilitate installation and transportation, and enhance aesthetic appeal.

[0131] The fan receiving portion (320) may be coupled to the duct body (310) or may be provided to be supported inside the duct body (310) to receive the circulation fan (330).

[0132] The fan receiving portion (320) may be positioned rearward from the front of the duct body (310) to secure a space into which air discharged from the front of the drum (150) may be introduced. In addition, the fan receiving portion (320) may be positioned close to or in close contact with the drying module (20) to form a path for delivering the air to the drying module (20).

[0133] The above duct module (30) may further include a filter unit (350) that is positioned in front of the fan receiving unit (320) and filters foreign substances flowing into the circulation fan (330).

[0134] The above filter unit (350) is provided in front of the fan receiving unit (320) with a length corresponding to the width of the duct body (310) so as to be able to filter foreign substances discharged from a large amount of clothing without difficulty.

[0135] The filter unit (350) may be detachably provided on the duct body (310) so that accumulated foreign substances can be easily removed. The duct body (310) may include an entrance through which the filter unit (350) is introduced and withdrawn, and the entrance may be arranged at the front of the duct body (310). Accordingly, a user can check the status of the filter (350) and clean it without being limited by the configuration of the drying module (20) or the door (120).

[0136] The above drying module (20) may be arranged at the rear of the cabinet (110) to supply hot air and steam to the interior of the cabinet (110).

[0137] The above drying module (20) may be arranged so that the front lower part faces the duct module (30) and the front upper part faces the back surface of the drying body (10) or the drum (150).

[0138] The above drying module (20) may include a case (210) placed at the rear of the cabinet (110) and a heat exchange unit (240) placed inside the case (210) to dehumidify and heat the air.

[0139] The case (210) may be provided at a height that allows it to face the entire back surface of the drum (150) from the bottom of the duct module (30). The width of the case (210) may be provided to correspond to the width of the cabinet (110) or may be provided to be smaller. Accordingly, the case (210) may be installed without any problem in any space where the cabinet (110) can be installed.

[0140] The front-to-back thickness of the case (210) may be set to be smaller than the front-to-back thickness of the cabinet (110) and the duct module (30). As a result, the volume of the clothing removal device of the present invention can be designed to be compact.

[0141] The drying module (20) may further include a flow path forming part (220) disposed inside the case (210) to guide air discharged from the duct module (30) back to the drum (150). At least a portion of the heat exchange part (240) may be disposed inside the flow path forming part (220).

[0142] The heat exchange unit (240) may include an evaporator (241) installed in the flow path forming unit (220) and a condenser (242) positioned above the evaporator (241). The clothes treatment device of the present invention may further include a washing unit (270) that sprays water onto the heat exchange unit (240) to wash the clothes, and a water supply unit (260) that supplies water to the washing unit (270). The detailed structure and function of the corresponding components will be described later. The flow path forming unit (220) may be provided to extend in the height direction of the cabinet (110) or the case (210) to receive air discharged from the duct module (30) and guide it to the rear surface of the drum (150).

[0143] Figure 6 illustrates an embodiment of the front configuration of the garment treatment device of the present invention.

[0144] The cabinet (110) forming the exterior of the above-mentioned drying body (10) may include a front panel (111) arranged in front of the drum (150) and side panels (113) extending rearward from both sides of the front panel (111).

[0145] When the above duct module (30) is installed inside the cabinet (110), the drying body (10) may further include a cover panel (112) provided to shield the front of the duct body (310).

[0146] The above cover panel (112) can be arranged parallel to the front panel (111) and can be provided with a width corresponding to the width of the front panel (111).

[0147] The height of the cover panel (112) may be provided to be smaller than the height of the front panel (111), and may be provided to be smaller than the width of the cover panel (112).

[0148] The above front panel (111) may be provided with a height longer than its width.

[0149] The drying body (10) may further include a control panel (190) on the upper part of the front panel (111) for receiving a command to control the garment treatment device of the present invention or for displaying the status of the garment treatment device of the present invention.

[0150] The above-mentioned drying body (10) may further include a payment device for receiving payment, which is placed on one side of the control panel (190). The payment device may be equipped with any payment method capable of processing payment by inserting coins, communicating with a card, smartphone, etc.

[0151] The front panel (111) may be provided with an opening (1111) that connects the drum (150) to the outside. The drying body (10) may further include a door (120) that opens and closes the opening (1111), and the door (120) may be rotatably coupled to the front panel (111) or rotatably coupled to the front panel (111) by a hinge joint (130) arranged inside the cabinet (100) to open and close the opening (1111).

[0152] Figure 7 illustrates an embodiment of the door structure of the garment treatment device of the present invention.

[0153] Referring to Fig. 7(a), the door (120) may include an outer frame (121) that is formed to be larger than the area of ​​the opening (1111) and is exposed to the outside, an inner frame (122) that is coupled to the outer frame (122) to open and close the opening (1111), and a hinge part (125) that is arranged between the inner frame and the outer frame and rotates the door (120) relative to the cabinet (110).

[0154] The inner frame (122) may include a door sealer (124) that adheres closely to the inner surface of the opening (1111) to prevent hot air from leaking out of the opening (1111). The door sealer (124) may be provided in a shape corresponding to the opening (1111).

[0155] The inner frame (122) and the outer frame (121) may have a through hole formed through the center to visually expose the inside of the opening (1111), and the door (120) may further include glass (123) that is bonded between the inner frame (122) and the outer frame (121) to shield the through hole and allow light to pass through.

[0156] The inner frame (122) may be provided with a protrusion on its inner surface so that at least a portion thereof is inserted into the inner surface of the opening (1111), and the door sealer (124) may be provided with an elastic material that is combined to surround the circumference of the protrusion.

[0157] Meanwhile, the inner frame (122) may additionally be provided with a fixing member (126) that is provided to be detachably connected to a fastening member provided on the front panel (111).

[0158] The above door (120) may further include a handle (127) that can be grabbed by the user's body by having the outer surface of at least one of the inner frame (122) or the outer frame (121) sunken inward.

[0159] The above fixed part (126) and fastening part may be configured with a conventional hook and hook fastening part.

[0160] However, the garment treatment device of the present invention can omit a configuration such as a locking part that locks the door (120) to the front panel (111) to prevent the door (120) from being opened. As a result, the thickness of the front panel (111) and the door (120) can be reduced, and the length of the drum (120) can be further secured, thereby further increasing the drying capacity.

[0161] Referring to FIG. 7(b), the outer frame (121) may include an outer body (1211) that forms an exterior and has a center that is penetrated to expose glass (123), a joining protrusion (1213) that is arranged on the inner surface of the outer body (1211) and is coupled to the inner frame (122), and a grounding protrusion (1212) that is provided to be able to penetrate the inner frame (122) and contact the front panel (111).

[0162] An elastic material is combined with the above grounding protrusion (1212), so that even if the door (120) collides with the front panel (111), the door (120) can be prevented from being damaged.

[0163] The above grounding protrusion (1212) and the above coupling protrusion (1213) may be provided in multiple numbers.

[0164] Figure 8 illustrates an embodiment of the front structure of the garment treatment device of the present invention.

[0165] The front panel (111) may be provided with an opening (1111) that penetrates the front panel, and the opening (1111) may be provided with a shape corresponding to the inner shape of the door (120).

[0166] The front panel (111) may further include a hinge joint (130) to which the hinge joint (125) can be coupled to at least one of both sides of the opening (1111).

[0167] The above hinge joints (130) can be arranged in multiple numbers spaced apart from each other in the vertical direction on one side of the opening (1111).

[0168] In addition, the hinge joint (130) may be arranged on both sides of the opening (1111). The door (120) may be coupled to the hinge joint (130) arranged on the left side of the opening (1111), or may be coupled to the hinge joint (130) arranged on the right side of the opening (1111), as needed. Accordingly, the garment treatment device of the present invention can selectively determine the rotational direction in which the door (120) opens and closes the opening (1111) depending on the location where the cabinet (110) is installed.

[0169] The above cover panel (112) can be detachably provided on the front of the duct body (310) at the lower portion of the front panel (111).

[0170] The cover panel (112) may be rotatably coupled at the lower portion to the lower portion of the duct body (310) or the bottom panel of the cabinet (110), and may be detachably coupled at the upper portion to the upper portion of the duct body (310) or the lower portion of the front panel (111). As a result, even if the duct body (310) is opened, the cover panel (112) may be prevented from being lost.

[0171] The width of the duct body (310) may be provided to correspond to the width of the cabinet (110) so that a sufficient amount of flow can move. In addition, the front opening of the duct body (310) may be provided to correspond to the width of the duct body (310) so that the filter unit (350) can be easily withdrawn.

[0172] The above filter unit (350) is provided to allow air to pass through and may be provided in a plate shape.

[0173] The filter unit (350) may be arranged to be inclined with respect to the height direction of the duct body (310). For example, the filter unit (350) may be arranged so that the upper and lower surfaces are in close contact with the inner surface of the duct body (310), and the upper surface may be arranged forward or backward relative to the lower surface. As a result, the cross-sectional area through which air passes in the filter unit (350) may be provided to be much larger than the cross-sectional area in the front-rear direction of the duct body (310), so that the filtration performance may be maximized.

[0174] The above filter unit (350) may include a frame coupled to the inner surface of the duct body (310) and a mesh member that shields the internal space of the frame and allows air to pass through while filtering out foreign substances.

[0175] The above filter unit (350) is detachably provided inside the duct body (310) and can be inserted into the front opening of the duct body (310).

[0176] Figure 9 illustrates an embodiment of the internal configuration of the garment treatment device of the present invention viewed from the front.

[0177] The above cabinet (110) can have a reinforcing frame (115) for fixing the side panel (113) placed at least on one of the front and rear of the side panel (113).

[0178] The above front panel (111) can be fixed by being combined with the above reinforcing frame (115).

[0179] A rotatable drum (150) may be placed inside the cabinet (110). The drum (150) may have an inlet (1531) positioned at the front that communicates with the opening (1111).

[0180] The above drying body (10) may further include a housing (140) that is accommodated inside the cabinet (110) and accommodates the drum (150).

[0181] In general, in the case of a household dryer, the drum (150) is provided in a cylindrical shape without a through hole formed on the circumference, and a support plate that rotatably supports the drum (150) is formed on the front and rear of the drum, and a duct through which the air is communicated with a duct module (30), etc., may be installed on the support plate.

[0182] However, in the case of a commercial dryer, the diameter and length of the drum (150) are much larger than those of a household dryer, and it is highly likely that a larger volume of clothes will be loaded into the drum (150) than in a household dryer.

[0183] Moreover, when a large amount of clothing is wet in the drum (150), the weight inside the drum (150) is much greater than that of a household dryer, so it is difficult to stably support the drum (150) with a resin-based support plate generally applied to a household dryer.

[0184] In addition, in order to dry a large amount of clothing accommodated in the drum (150), sufficient flow rate must be secured, but a duct through which the flow rate can pass cannot be installed with a resin-based support plate generally applied to household dryers, and even if the duct can be installed, the problem of the front and rear length of the cabinet (110) becoming excessively long may occur.

[0185] To improve this, the garment treatment device of the present invention can accommodate the drum (150) through the housing (140) and stably support the drum (150) through the lower surface.

[0186] The above housing (140) may be made of a metal material to stably support the support member (170) that supports the drum (150), and may be thicker than the cabinet (110).

[0187] In addition, the housing (140) is provided with a larger cross-sectional area than the drum (150) and is provided in a duct shape capable of moving air, so as to secure the maximum amount of hot air supplied to the inside of the drum (150).

[0188] In addition, the housing (140) is provided to receive air from the drying module (20) through the rear and guide the air to the duct module (30) from the front, thereby eliminating the need for a separate duct to be formed in the front or front panel (111) of the drum (150).

[0189] Specifically, the housing (140) may be provided with an outlet on the bottom surface that supports at least a portion of the load of the drum (150) to discharge air introduced into the housing (140) to the duct module (30). The width of the outlet may be expanded to the maximum extent to the width of the bottom surface of the housing, and the width of the outlet in the front-back direction may be sufficiently expanded in the front-back direction of the bottom surface of the housing. As a result, by securing the area of ​​the outlet, the garment treatment device of the present invention may supply sufficient air to the housing (140).

[0190] In addition, the drum (150) is provided with a discharge hole on a portion of its circumference, so that even if the drum (150) is extended in length to the front panel (111), air inside the drum (150) can be easily discharged through the discharge hole. As a result, the clothing treatment device of the present invention can secure a sufficient flow rate to dry a large amount of clothing as a commercial dryer.

[0191] Specifically, the housing (140) can be placed between the cabinet (110) and the drum (150) to form a path through which air moves.

[0192] The housing (140) may be provided in a duct shape to accommodate the drum (150) and prevent hot air supplied to the drum (150) from leaking out of the cabinet (110).

[0193] The above housing (140) may be provided so that the front and rear of the drum (150) are open, but the circumferential direction of the drum (150) is shielded.

[0194] The housing (140) may be provided so that the rear can communicate with the drying module (20) and the front can contact the front panel (111). As a result, hot air supplied from the drying module (20) can be guided to the front of the drum (150).

[0195] In addition, the housing (140) may be provided to communicate with the duct module (30). In order for the hot air supplied from the drying module (20) to sufficiently travel to the front of the drum (150), the housing (140) and the duct module (30) may be provided to communicate at a position closer to the front panel than the rear panel of the cabinet (110).

[0196] The above drying body (10) may further include a support member (170) that rotatably supports the drum (150) within the cabinet (110). As a result, the drum (150) can rotate stably within the cabinet (110) without vibration or positional change exceeding a reference value while holding heavy or large quantities of clothing.

[0197] The housing (140) can be secured and supported by at least a portion of the support member (170). To this end, the housing (140) can be secured and fixed to the upper portion of the duct module (30).

[0198] The above support member (170) may be arranged on the bottom surface of the housing (140) and the outer circumferential surface of the drum (150), and may also be arranged on the lower sides of both sides of the drum (150).

[0199] The above housing (140) may be provided with a different shape from the drum (150) as long as it can accommodate the drum (150) and guide hot air to the front of the drum (150).

[0200] For example, the drum (150) may have a circular cross-section in the diametric direction, but the housing (140) may have a polygonal cross-section in the height direction.

[0201] The above hinge joint (130) can be fixed by being joined to the housing (140).

[0202] The above hinge joint (130) can be coupled to both sides of the housing (140), and can be coupled to the inner surface of the housing (140) so that the coupling between the housing (140) and the side inner wall (113) of the cabinet is not obstructed.

[0203] The above housing (140) may be made of a metal material and may be provided to support the support member (170) and the hinge joint member (130).

[0204] Meanwhile, the housing (140) can support the driving unit (160) from the outside of the housing (140).

[0205] The above hinge joint (130) is fixed by being joined to the inner surface of the housing (140).

[0206] Accordingly, the hinge joint (130) is placed between the drum (150) and the housing (140).

[0207] In addition, the hinge joint (130) can be fixed by being coupled to the hinge joint (125) of the door at the front, and the front panel (111) can also be fixed thereto. The hinge joint (125) of the door can be arranged forward of the front panel (111) and coupled to the hinge joint (130). Accordingly, when the hinge joint (125) is coupled to the hinge joint (130), the front panel (111) can also be coupled to the hinge joint (130) and fixed thereto.

[0208] The above hinge-connecting portions (130) can be arranged two vertically on the inner surface of one side of the housing (140) and two vertically on the inner surface of the other side, and the hinge portions (125) can be selectively coupled to the hinge-connecting portions (130) arranged on the one side and the hinge-connecting portions (130) arranged on the other side. The hinge-connecting portions (130) can be arranged so as to be spaced apart from each other at a distance so as to be coupled to the hinge portions (125) on one side of the housing (140), and the hinge-connecting portions (130) can be arranged so as to be spaced apart from each other at a distance so as to be coupled to the hinge portions (125) on the other side of the housing (140). As a result, the direction in which the door (120) opens can be selectively changed.

[0209] The hinge joint (130) may be formed of a material different from that of the cabinet (110) and the housing (140). For example, it may be formed of a material having stronger rigidity than that of the cabinet (110) and the housing (140). Accordingly, even if the door (120) is subjected to a considerable load, it may be stably fixed to the housing (140).

[0210] The hinge joint (130) may be positioned spaced apart from both the top and bottom of the housing (140). The hinge joint (130) may be positioned so that the length spaced apart from the bottom surface of the housing (140) is greater than the length spaced apart from the top of the side plate of the housing (140).

[0211] Figure 10 illustrates an embodiment of a sealing structure of a clothing treatment device of the present invention.

[0212] The housing (140) may be provided with an open front so that the drum (150) can be easily installed or replaced inside the housing (140).

[0213] The clothing treatment device of the present invention may include a sealing part (180) provided in the drying body (10) to prevent hot air or steam supplied from the drying module (20) from leaking out of the cabinet (110).

[0214] When the sealing portion (180) includes a front sealer (181) that seals the front of the housing (140), the front sealer (181) can be fixed by being combined with at least one of the front panel (111) and the housing (140).

[0215] The above front sealer (181) may be provided to prevent hot air from leaking out of the front panel (111) and the outside of the housing (140).

[0216] The above front sealer (181) may be provided in a shape corresponding to the front surface of the housing (140) and may be placed outside the drum (150).

[0217] The above front sealer (181) can be placed completely spaced apart from the front of the drum (150).

[0218] Since the sealing portion (180) is not installed on the drum (150), friction at the front of the drum (150) can be omitted by a separate structure. Accordingly, the power of the driving portion (160) can be more focused on rotating the drum (150).

[0219] The configuration of the above sealing portion will be described in detail later.

[0220] Figure 11 illustrates an example of the arrangement position of the driving unit of the garment treatment device of the present invention.

[0221] The driving unit (160) of the garment treatment device of the present invention can be supported by being installed on the upper portion of the housing (140). The housing (140) is made of a metal material and can stably support the driving unit (160).

[0222] The above driving unit (160) may be provided as a belt / pulley type and may be provided to rotate the drum (150). Accordingly, when the driving unit (160) is positioned above the drum (150), the belt wound around the outer circumference of the drum (150) may also provide a force to support the drum (150).

[0223] Accordingly, even if a large amount of clothing or heavy clothing is placed in a wet state inside the drum (150), the drum (150) can rotate stably inside the housing (140).

[0224] In addition, the belt connecting the driving unit (160) and the drum (150) can have its tension stably maintained by the load of the drum (150) even as time passes.

[0225] Specifically, the driving unit (160) of the garment treatment device of the present invention may include a driving motor (161) that provides power to rotate the drum (150), a belt (162) that is provided to rotate by the driving motor (161) and comes into contact with the outer surface of the drum (150), and a fixing unit (163, 164) that fixes the driving motor (161) to the upper portion of the housing (140).

[0226] The above-mentioned fixing part (163, 164) may include a front fixing part (163) that is arranged in front of the driving motor (161) and is mounted on the upper surface of the housing (140), and a rear fixing part (164) that is arranged in the rear of the driving motor (161) and is arranged to face the front fixing part (163).

[0227] The above front fixing part (163) and the above rear fixing part (164) can also perform the role of fixing the side panels (113) on both sides of the cabinet.

[0228] The driving unit (160) may further include a swing unit (165) coupled to the front fixing unit (163) and the rear fixing unit (164) to support the driving motor (161). The swing unit (165) may be provided such that one side thereof is rotatably coupled to the front fixing unit (163) and the rear fixing unit (164) in the height direction and the other side thereof supports the driving motor (161). Accordingly, when the drum (150) vibrates or its position slightly changes during rotation, the swing unit (165) reciprocates accordingly to prevent excessive shock from being transmitted to the driving motor (161), and also prevents the tension of the belt (161) from changing suddenly.

[0229] The upper surface of the housing (140) can be spaced downward from the upper panel (117) of the cabinet to secure a space in which the driving unit (160) can be installed.

[0230] That is, the housing (140) may have a bottom surface and both sides in the shape of a flat plate, but the upper surface of the housing (140) may have a polygonal shape such as a trapezoid.

[0231] For example, the housing (140) is provided so that both sides are formed lower than the central portion according to the shape of the drum (150), so that a space can be secured for the driving unit (160) to be installed between the drum (150) and the cabinet (110).

[0232] The housing (140) may include an upper plate (143) that is positioned on top of the drum (150) and supports the driving unit (160).

[0233] The upper plate (143) may include an inclined plate (1431) that extends high from the side panel (113) of the cabinet (110) toward the upper portion of the drum (150).

[0234] The above-mentioned inclined plate (1431) is provided so that its height decreases as it extends from the central portion of the drum (150) toward the side panel (113) of the cabinet (110), thereby securing a space in which the driving unit (160) can be installed at the upper ends on both sides of the drum (150).

[0235] Additionally, the upper plate (143) may include an extension plate (1432) that extends from the upper end of the inclined plate (1431) toward the upper end of the drum (150) so as to maintain a height. The extension plate (1432) may be arranged parallel to the upper panel (117) of the cabinet or the bottom surface (141).

[0236] The above-mentioned inclined plate (1431) and the above-mentioned extension plate (1432) may be provided as flat plates without any bends. Accordingly, even if a portion having a different height is provided on the upper plate (143), the occurrence of an area where residual stress is concentrated can be prevented in advance.

[0237] The above extension plate (1432) can prevent the above inclined plate (1431) from being extended excessively or its upper height from becoming excessively high, and the front fixing part (163) and the rear fixing part (164) can be stably supported so that the left and right sides are balanced.

[0238] The above-mentioned inclined plate (1431) may be provided to extend from both ends of the extension plate (1432) toward the side panel (113) in a lower height, and may be formed symmetrically with respect to the extension plate (1432).

[0239] The housing (140) may further include a bottom surface (141) that supports the support member (170) and is positioned on top of the duct module (30), and double-sided plates (142) that extend upward from both sides of the bottom surface (141) and are positioned to face the side panel (113) and can be fixed to the side panel (113), and the upper plate (143) may be provided to connect the double-sided plates (142) to each other.

[0240] Figure 12 illustrates an example of the rear structure of the garment treatment device of the present invention.

[0241] The above drying module (10) may further include a rear support member (172) on the rear surface that rotatably supports the drum (150).

[0242] The above rear support member (172) can form a center of rotation around which the drum (150) rotates and can serve as a rotation axis of the drum (150).

[0243] The above rear support member (172) can be fixed by being joined to the rear panel (114) forming the rear of the cabinet (110).

[0244] The above rear panel (114) can be fixed by being combined with the side panels (113) of the cabinet (110) and the rear surface of the housing (140).

[0245] The above rear support member (172) may include a rotation shaft (1721) coupled to the rear rotation center of the drum (150) and a bracket (1722) that fixes the rotation shaft (1721) to the rear panel (114).

[0246] The above sealing portion (180) may further include a rear sealer (182) that seals between the back surface of the drum (150) and the rear panel (114).

[0247] The above bracket (1722) is fixed to the inner surface of the rear panel (114) and may be made of a metal material that is stronger or thicker than the rear panel (114). The above rotational shaft (1721) may be provided such that one end is rotatably coupled to the bracket (1722) and the other end is coupled to the drum (150) so as to rotate integrally with the drum (150).

[0248] The above-mentioned rotation shaft (1721) serves to rotatably support the drum (150), and the power to directly rotate the drum (150) can be provided by the driving unit (160). As a result, the configuration of a separate driving unit (160) between the rear of the drum (150) and the rear panel (114) is omitted, thereby further securing the volume of the drum (150) and further reducing the gap between the drying module (20) and the drum (150).

[0249] The driving unit (160) may be positioned closer to the rear of the drum (150) than to the front. Specifically, the driving unit (160) may be positioned closer to the rear panel (114) than to the front panel (111). This prevents the driving unit (160) from interfering with the discharge hole provided in the drum (150) described below.

[0250] Figure 13 illustrates an embodiment of the drum structure of the garment treatment device of the present invention.

[0251] The above housing (140) may be provided in a case shape with the front open to accommodate the drum (150).

[0252] The housing (140) may be configured to have an open rear end. For example, the housing (140) may be composed of a bottom surface (141), a side plate (142), and an upper plate (143).

[0253] The rear surface of the housing (140) may serve as an inlet for air to flow into the drying module (20). In addition, a through hole formed through the bottom surface (141) of the housing (140) may serve as an outlet (1411) for discharging the air to the duct module (30).

[0254] The above discharge port (1411) may be provided in the shape of a slit that penetrates the bottom surface (141) longer in the width direction than in the front-back direction.

[0255] The above drum (150) can be inserted from the front of the housing (140) and coupled to the rear support member (172) coupled to the rear panel (114).

[0256] The above drum (150) may include a drum body (151) having a cylindrical shape and providing a space for accommodating clothing.

[0257] The drum (150) may further include a front body (153) that is coupled to the front of the drum body (151) to maintain the shape of the drum body (151) and prevent the clothing from being randomly discharged from the drum body (151).

[0258] The above front body (153) is provided in a ring shape so that an inlet for inserting the clothing can be formed in the center.

[0259] The drum (150) may include a lifter (157) that is coupled to the inner surface of the drum body (151) to elevate the clothing, and may further include a rear body that is coupled to the rear of the drum body (151) and fixed to the rear support member (172).

[0260] The above drum (150) may further include an exhaust hole (154) through which hot air can move by penetrating the drum body (151).

[0261] The above discharge holes (154) may be provided in multiple numbers along the circumference of the drum body (151). Meanwhile, the discharge holes (154) may be positioned further forward than backward of the drum body (151). As a result, the hot air introduced into the drum body (151) can move as far as possible to the front of the drum body (151), thereby drying more clothes.

[0262] The above discharge port (1411) may be arranged closer to the front than the rear of the bottom surface (144). The discharge hole (154) may be arranged in an area facing the discharge port (1411). The discharge hole (154) may be formed to be much longer than the width of the discharge port (1411) in the front-back direction. However, the discharge hole (154) may be arranged closer to the front than the rear of the drum body (151) so that at least a portion of the discharge hole (154) may overlap with the discharge port (1411) in the height direction. As a result, the air introduced into the drum body (151) may be discharged while moving as close to the discharge port (1411) as possible.

[0263] Meanwhile, the discharge hole (154) and the outlet (1411) can serve as a path for moving air, and the discharge hole (154) can be provided with a length corresponding to the diameter of the drum (150), and the outlet (1411) can be provided with a width corresponding to the width of the bottom surface (144). As a result, the garment treatment device of the present invention can omit a separate duct structure that is arranged in front of the drum (150) and guides the air discharged from the drum (150) to the duct module (30), and can prevent the length of the cabinet (110) from being excessively expanded in the front-to-rear direction while also extending the length of the drum (150) as much as possible, thereby sufficiently securing a drying capacity suitable for a commercial dryer.

[0264] Figure 14 illustrates an example of a drum rear structure of a garment treatment device of the present invention.

[0265] The drum (150) may include a rear body (152) that is coupled to the rear of the drum body (150) and forms the back surface of the drum (150). The rear body (152) may be formed in a circular shape and may be coupled to the rear peripheral surface of the drum body (150).

[0266] The rear body (152) prevents the clothing from being detached from the rear of the drum (150) and allows the drum (150) to rotate around the rotation axis (1721).

[0267] The above rear body (152) may be provided to face the outlet through which hot air is discharged from the drying module (20).

[0268] The drum (150) may include a plurality of inlet holes (155) that penetrate the rear body (152) and introduce the hot air into the drum body (151).

[0269] The rear body (152) may have a connecting portion (157) positioned at the center facing the rotation axis (1721) and forming the center of rotation of the drum. The inlet hole (155) may be positioned between the inner surface of the rear body (152) and the outer surface of the connecting portion (157).

[0270] The rear body (152) may further include a plurality of radial ribs extending from the connecting portion (157) toward the inner circumferential surface of the rear body (152), and the inlet hole (155) may be formed between the radial ribs. The rigidity of the rear body (152) may be further reinforced through the radial ribs.

[0271] The above inlet hole (155) can be formed in an area sunken into the drum body (151) on the inner surface of the rear body (152). The lifter (156) can be fixed by having its rear end joined to the front surface of the inner surface of the rear body (152) and one end joined to the back surface of the front body (153).

[0272] The above drum (150) may further include at least one of a bushing portion (158) that reinforces the rigidity of the above coupling portion (157) and a shaft coupling portion (159) that is coupled to the bushing portion (158) and fixes the rotation shaft (1721).

[0273] The above bushing part (158) is made of a material that is thicker than the above connecting part (157) or has higher strength than the above connecting part (157) so as to stably support the above rotating shaft (1721).

[0274] The above-mentioned shaft coupling portion (159) may be provided in a disk shape that is coupled to the free end of the rotation shaft (1721) and has a diameter much larger than the diameter of the rotation shaft (1721). The shaft coupling portion (159) is coupled to the bushing portion (158) with a larger area than the rotation shaft (1721), so that even if an excessive load is applied to the rotation shaft (1721), the rotation shaft (1721) can be prevented from being detached or separated from the drum (150).

[0275] The above-mentioned shaft coupling portion (159) may also be provided with a material that is thicker than the above-mentioned coupling portion (157) or has higher strength than the above-mentioned coupling portion (157). The diameter of the above-mentioned shaft coupling portion (159) may be provided to be smaller than the diameter of the above-mentioned bushing portion (158).

[0276] Because the rear body (152) can be made of a relatively thin and light material due to the above bushing portion (158) and the above shaft coupling portion (159), the manufacturing cost of the drum (150) can be reduced, and the rotational moment for rotating the drum (150) can be lowered, thereby reducing the load on the driving portion (160).

[0277] The above rear body (152) can be folded rearward from the inner surface to secure an area or space where the rear sealer (182) can be installed.

[0278] The rear sealer (182) may be provided to surround the outermost portion of the inlet hole (155) and may be arranged along the inner circumference of the rear body (152). The entire area of ​​the outlet of the drying module (20) may be arranged within the rear sealer (182), and the rear sealer (182) may guide all of the supplied hot air to the inlet hole (155). Fig. 15 illustrates an embodiment of a duct module of the clothing treatment device of the present invention.

[0279] The above duct module (30) may include a duct body (310) on which a filter unit (350) can be installed, a fan receiving unit (320) positioned at the rear of the duct body (310) to suck in air with negative pressure, and a blower fan (330) installed in the fan receiving unit (320) to form the negative pressure.

[0280] The above duct body (310) may be provided to provide a space within which air discharged from the housing (140) moves. The above duct body (310) may be provided in the shape of a case, or may be provided in the form of a combination of frames forming a rectangular parallelepiped and the frames shielded with a plate.

[0281] The above duct body (310) may be provided with a high-strength metal material to support the drying body (10).

[0282] The fan receiving portion (320) may be mounted on the duct body (310). The fan receiving portion (320) may be positioned at the rear of the duct body (310) and may be positioned at the rear of the filter portion (350).

[0283] The fan receiving portion (320) may form a flow path that receives air from the front and discharges it from the rear. The fan receiving portion (320) may further include a fan fixing portion (340) at the front for fixing the circulation fan (330) to the fan receiving portion (320). Accordingly, even if the front of the fan receiving portion (320) is opened to a greater diameter than the circulation fan (330), the fan fixing portion (340) can prevent the circulation fan (330) from being separated from the fan receiving portion (320) and protect the circulation fan (330) from external impacts or foreign substances.

[0284] The above circulation fan (330) may be arranged to be offset to either the left or right side of the duct body (310) or the fan receiving portion (320). As a result, the area of ​​the vortex or dead zone where air does not flow can be reduced compared to when the circulation fan (330) is arranged in the center of the duct body (310) or the fan receiving portion (320).

[0285] The above duct module (30) may further include a partition panel (313) that is arranged in front of the fan receiving portion (320) in the duct body (310) and partitions the duct body (310) in the front-rear direction.

[0286] The above partition panel (313) may be provided to shield an area excluding the inlet area among the open areas of the fan receiving portion (320), and may fix the fan receiving portion (320) to the duct body (310).

[0287] The fan fixing part (340) can be fixed by being combined with the partition panel (313). The fan fixing part (340) is positioned to face the circulation fan (330), and an area facing the center of the circulation fan (330) can be penetrated to serve as an inlet for air to flow into the fan receiving part (320).

[0288] Figure 16 illustrates an example of installing a circulation fan of the clothing treatment device of the present invention.

[0289] The duct body (310) of the clothing treatment device of the present invention may include a first body (311) forming a bottom surface, and a second body (312) positioned at the rear of the first body (311) to support the fan receiving portion (320).

[0290] The above first body (311) can be supported by the filter unit (350) being installed thereon.

[0291] The above second body (312) may be provided to support the load of the fan receiving portion (320) and the circulation fan (330).

[0292] Referring to Fig. 16(a), the fan receiving portion (320) has a space in which the circulation fan (330) is installed, and may include a mounting portion (321) into which air introduced into the duct body (310) is sucked, and a connecting portion (322) that extends to the rear of the mounting portion (321) or is positioned at the rear of the mounting portion (321) to form a path for transmitting air discharged by the circulation fan (330) to the drying module (20).

[0293] The above-mentioned mounting portion (321) and the above-mentioned connecting portion (322) may be provided with a material that can be manufactured using a foaming method. Accordingly, even if the mounting portion (321) and the above-mentioned connecting portion (322) are provided with a complex structure to form a flow path therein, they can be manufactured to have a thicker thickness than when manufactured with a metal material or resin series. As a result, even if the circulation fan (330) is provided to be large enough to generate a large flow rate, the fan receiving portion (320) itself can absorb noise, the mounting portion (321) and the above-mentioned connecting portion (322) can also ensure durability against high flow rates, and the overall weight of the fan receiving portion (320) can be greatly reduced.

[0294] Additionally, materials that can be manufactured using the foaming method generally have very low thermal conductivity. Therefore, even if the fan housing (320) has a large volume and high-temperature hot air moves inside, the heat loss rate can be significantly reduced compared to when manufactured using metal or resin materials.

[0295] The above-mentioned mounting portion (321) may have an open surface formed in the front through which air flows. The mounting portion (321) may have a space formed on one side to accommodate the circulation fan (330), and a flow path formed on the other side to guide air supplied from the circulation fan (330) in the width direction of the duct body (310).

[0296] The above partition panel (313) may be provided to be coupled to the front of the mounting portion (321) to shield a portion of the open surface of the mounting portion (321) except for the protective panel (333).

[0297] The above connecting portion (322) may be positioned on the other rear side of the mounting portion (321) and may extend to the front of the drying module (20). The connecting portion (322) may have a path formed therein through which air moves, and an exhaust port provided on the rear surface through which air is discharged.

[0298] The above-mentioned connecting portion (322) is provided separately from the above-mentioned securing portion (321) and can be fixed by being joined to the rear of the securing portion (321) through a force-fit method or a fastening member, etc. Thus, even if the extension directions of the flow paths formed inside the securing portion (321) and the connecting portion (322) are different from each other, the connecting portion (322) can be manufactured without difficulty using a foaming method.

[0299] The above circulation fan (330) may include an impeller (331) that generates power to move air and a fan motor (332) coupled to the impeller (331) to rotate the impeller (331).

[0300] Referring to Fig. 16(b), the circulation fan (330) may be supported by being coupled to at least one of the mounting portion (321) and the connecting portion (322). In this case, if the mounting portion (321) and the connecting portion (322) are made of a material capable of foam molding rather than a metal or resin series, the rigidity for supporting the circulation fan (330) may be insufficient.

[0301] To this end, the clothing treatment device of the present invention may include a fan fixing unit (340) that is coupled to the fan receiving unit (320) and fixes the installation position of the circulation fan (330).

[0302] The above fan fixing part (340) may be made of a material with higher strength than the foam material.

[0303] For example, the fan fixing part (340) may include a fixing plate (341) made of a metal plate shape that can be fixed by being fixed upward by being fixed to the second body (312).

[0304] The impeller (331) may be placed in front of the fixed plate (341) and may be placed inside the fan receiving portion (320), and the fan motor (332) may be placed in the rear of the fixed plate (342) and may be placed outside the fan receiving portion (320).

[0305] The above fixed plate (341) may further include a through hole through which the fan motor (332) may pass. Accordingly, the circulation fan (330) may be coupled to the fixed plate (341) by inserting the fixed plate (341) into the through hole.

[0306] The above fan fixing unit (340) may further include a fixing plate (342) that is positioned between the fan motor (332) and the impeller (331) and coupled to the fixing plate. The fixing plate (342) may be provided to shield the through hole and may fix the circulation fan (330) to the fixing plate (341).

[0307] Figure 17 illustrates an example of the appearance of a drying module (20).

[0308] Referring to Fig. 17(a), the drying module (20) may include a case (210) arranged at the rear of the drying body (10) and the duct module (30). The case (210) may be arranged at the rear of the cabinet (110).

[0309] The above case (210) may be provided in a rectangular parallelepiped shape, and its height may be provided to be equal to or smaller than the entire height of the cabinet (110).

[0310] Referring to Fig. 17(b), the case (210) may include a flow path forming part (220) that forms a flow path for supplying air from the duct module (30) to the drying body (10), and an auxiliary flow path part (230) that is arranged on one side of the flow path forming part (220) and forms a flow path for communicating the case (210) with external air. The flow path forming part (220) and the auxiliary flow path part (230) may be arranged to be partitioned from each other so that air therebetween does not move with each other.

[0311] A plurality of heat exchangers for dehumidifying and heating air may be installed inside the above-mentioned flow path forming part (220), and electrical components such as a compressor for supplying refrigerant for heat exchange with air to the auxiliary flow path part (230) may be installed.

[0312] The above-mentioned flow path forming part (220) may be provided so as to communicate with the duct module (30) and the housing (140) or drum (150) of the drying body (10) on the inside of the case (210), thereby forming a flow path through which the air of the drum (150) circulates.

[0313] The above-mentioned euro-forming portion (220) can be formed by extending in the height direction inside the case (210).

[0314] The above auxiliary flow path (230) can be placed on one side of the flow path forming part (220).

[0315] The above auxiliary flow path (230) may be provided with a height corresponding to the height of the flow path forming part (220), but may be provided with a width smaller than the width of the flow path forming part (220). As a result, the amount of fluid flowing in the flow path forming part (220) can be secured.

[0316] The auxiliary flow path (230) may be provided to be separated from the drying body (10) and the duct module (30) and communicate only with the outside air. Thus, the auxiliary flow path (230) may be prevented from being heated by hot air or exposed to foreign substances discharged from the drum (150). As a result, electrical components may be installed within the auxiliary flow path (230) and operate stably.

[0317] The above-mentioned euro-forming part (220) may be provided in the shape of a duct placed inside the case (210) so that air can flow.

[0318] However, in order to simplify the configuration of the drying module (20) and reduce the weight of the drying module (20), the flow path forming part (220) may be automatically formed due to the configuration of the case (210). For example, the flow path forming part (220) may be automatically formed through the arrangement of the front panel (219), the rear panel (212), the partition panel (218), and the side panel (211) forming the front of the case (210).

[0319] The above auxiliary flow path (230) can be automatically formed through the arrangement of the front panel (219), auxiliary panel (214), partition panel (218), and side panel (211).

[0320] The above auxiliary panel (214) may have multiple penetration holes installed in the height direction so that it can communicate with the outside air.

[0321] Referring again to Fig. 17(a), the case (210) may include side panels (211) forming both sides and a rear panel (212) coupled to the side panels (211) to form the rear of the case (210).

[0322] The rear panel (212) may be provided to form the back surface of the flow path forming part (220) and block the flow path forming part (220) from being exposed to the outside. In this case, the case (210) may further include an auxiliary panel (214) that is arranged on one side of the rear panel (212) to form the back surface of the auxiliary flow path part (230) and block the auxiliary flow path part (230) from being exposed to the outside.

[0323] The above auxiliary panel (214) and the above rear panel (212) can form the back surface of the case.

[0324] The case (210) may further include a detachable panel (213) that is detachably provided on the rear panel (212) to expose the internal heat exchanger to the outside. Accordingly, the heat exchanger can be cleaned or repaired or replaced by detaching only the detachable panel (213) from the rear panel (212) without detaching the entire rear panel (212) from the case (210).

[0325] The rear panel (212) may be provided with a back surface through which the heat exchanger is installed, and the detachable panel (213) may be detachably coupled to the through-hole area of ​​the rear panel (212).

[0326] Figure 18 illustrates an example of the internal configuration of the drying module.

[0327] Figure 18(a) illustrates the internal configuration of the case (210) in the drying module from the rear, and Figure 18(b) illustrates the internal configuration of the case (210) in the drying module from the front.

[0328] Referring to Fig. 18(a), the drying module (20) may include a heat exchanger (240) that is installed inside the case (210) and dehumidifies and heats the air supplied from the duct module (30) to generate hot air.

[0329] The above heat exchange unit (240) may include an evaporator (241) arranged in the flow path forming unit (220) to cool the air supplied from the duct module (20), and a condenser (242) to heat the air passing through the evaporator (241).

[0330] The above evaporator (241) and the above condenser (242) can be placed inside the flow path forming part (220) and can be placed in a vertical direction in the flow path forming part (220). The above condenser (242) can be placed above and spaced apart from the above evaporator (241).

[0331] The heat exchange unit (240) may further include a compressor (243) that receives refrigerant from the evaporator (241), heats it, and transfers it to the condenser (242), and an expansion valve (244) that expands the refrigerant that has passed through the condenser (242) to reduce the temperature and pressure of the refrigerant. The compressor (243) and the expansion valve (244) may be arranged inside the auxiliary flow path unit (230) and may be separated from the flow path forming unit (220).

[0332] The above heat exchange unit (240) may further include an auxiliary heat exchanger (245) connected to the condenser (241) and the evaporator (242) to exchange heat between the refrigerant and the outside air, and a switching valve (246) that selects whether the refrigerant delivered from the condenser (241) is supplied to either the expansion valve (244) or the auxiliary heat exchanger (245).

[0333] The above auxiliary heat exchanger (245) and the above switching valve (246) are also arranged inside the auxiliary flow path part (230) and can be separated from the flow path forming part (220).

[0334] The auxiliary heat exchanger (245) and the switching valve (246) may be positioned above the compressor (243), and the compressor (243) may be mounted on the bottom surface of the auxiliary flow path (230).

[0335] The above auxiliary flow path (230) may further include an auxiliary fan (231) that induces external air to come into contact with the auxiliary heat exchanger (245).

[0336] The auxiliary fan (231) may be positioned above the auxiliary heat exchanger (245). Thus, when the auxiliary fan (231) is driven, the outside air can cool the compressor (243) in the process of reaching the auxiliary heat exchanger (245).

[0337] The drying module (20) may further include a control panel (232) that provides a command to perform a drying process by controlling one or more of the auxiliary fan (231), the compressor (243), the expansion valve (244), and the switching valve (246). The control panel (232) may be installed in the auxiliary flow path (230) to prevent exposure to hot air passing through the flow path forming part (220). The control panel (232) may be arranged in a plate shape facing either the front or the rear of the auxiliary flow path (230). Accordingly, when the auxiliary fan (231) is driven, the control panel (232) may also be cooled by the outside air, and the control panel (232) may be prevented from interfering with the movement of the outside air supplied from the auxiliary flow path (230) to the auxiliary heat exchanger (245).

[0338] The auxiliary flow path (230) may further include an auxiliary partition plate (233) that blocks air passing through the auxiliary heat exchanger (245) from accessing the control panel (232). The auxiliary partition plate (233) may be arranged between the auxiliary heat exchanger (245) and the control panel (232) and may extend to an area where the auxiliary fan (231) is arranged.

[0339] Referring to Fig. 18(b), the front panel (219) forming the front of the euro forming part (230) may be arranged in front of the euro forming part (230) and spaced apart from the front of the auxiliary euro forming part (230).

[0340] Alternatively, the case (210) may further include an additional panel (219) that connects the partition panel (218) and the side panel (211) at the rear of the front panel (219) to form the front of the euro-forming portion (230).

[0341] The following description is based on an embodiment equipped with the above-mentioned additional panel (219), but the same can be applied to an embodiment equipped with only the above-mentioned front panel (219).

[0342] The above additional panel (219) may be provided with an inlet (215) through which air passing through the duct module (30) flows into the lower portion of the euro-forming portion (220), and an outlet (216) disposed above the inlet (215) through which air passing through the condenser (242) is discharged.

[0343] The inlet (215) may be positioned at a position facing the fan receiving portion (220) at the bottom of the evaporator (241), and the outlet (216) may be positioned at a position facing the rear body (152) of the drum (150) or the inside of the housing (140) at the rear panel (114) of the cabinet (110).

[0344] Accordingly, the air discharged from the outlet (3222) of the connection part (322) is introduced through the inlet (215), rises by the power of the circulation fan (330), passes through the evaporator (241) and the condenser (242) sequentially, is dehumidified and heated, and is discharged through the outlet (216) to be discharged into the housing (140) and the drum (150).

[0345] The above evaporator (241) can cool the air and condense moisture, and the condensed water can fall from the evaporator (241) and be collected on the bottom surface of the flow path forming part (220).

[0346] The above drying module (20) may include a drainage unit (250) that communicates with the bottom surface of the euro-forming unit (220) and discharges the condensate.

[0347] The above drainage unit (250) may include a drainage body (251) disposed on the bottom surface of the flow path forming unit (220) to collect water, and a drainage pipe (254) extending from the lower portion of the drainage body (251) to the outside of the case (210) to discharge water. Due to the drainage unit (250), water condensed in the flow path forming unit (220) may be prevented from evaporating again and flowing back into the drum (150), and the inside of the flow path forming unit (220) may be prevented from rotting.

[0348] The above drying module (20) may further include a cleaning unit (270) that can spray water onto the evaporator (241) to wash away foreign substances or remaining bacteria accumulated in the evaporator (241), and a water supply unit (260) that supplies water to the cleaning unit (270).

[0349] The above cleaning unit (270) may be provided to spray water toward the evaporator (241) from below the evaporator (241). In addition, the evaporator (241) may be arranged at an angle to increase the heat exchange area, thereby increasing the drying performance, and also to induce the water sprayed from the cleaning unit (270) to move along the surface of the evaporator (241) to wash away foreign substances.

[0350] The above drainage unit (250) can discharge all of the water sprayed from the cleaning unit (270) and foreign substances separated from the evaporator (241) to the outside of the drying module (20).

[0351] The above water supply unit (260) may also use water condensed in the above evaporator (241).

[0352] Alternatively, the water supply unit (260) may be provided to receive water directly from an external water source and supply it to the cleaning unit (270).

[0353] The above water supply unit (260) may include a water supply valve (261) that communicates with an external water supply source, and a water supply pipe (262) that is connected from the water supply valve (261) to the cleaning unit (270) and supplies the water to the cleaning unit (270).

[0354] The above control panel (280) may also be provided to control the water supply valve (261).

[0355] Figure 19 is a schematic diagram showing the structure in which the auxiliary heat exchanger of the clothing treatment device of the present invention is installed.

[0356] Figure 19 illustrates a state in which the switching valve (246) uses the auxiliary heat exchanger (245) as an evaporator, but the switching valve (246) can change the flow path state to a state in which the auxiliary heat exchanger (245) is used as a condenser.

[0357] Using the auxiliary heat exchanger (245) as an evaporator may correspond to a state in which the refrigerant that has passed through the condenser (242) passes through the switching valve (246) and the expansion valve (244) and is then guided to the auxiliary heat exchanger (245), and using the auxiliary heat exchanger (245) as a condenser may correspond to a state in which the refrigerant that has passed through the condenser (242) is guided directly to the auxiliary heat exchanger (245) through the switching valve (246).

[0358] Since the garment treatment device of the present invention is equipped with a commercial dryer, it is necessary to quickly dry a large quantity of garments. To this end, the garment treatment device of the present invention may consider increasing the cross-sectional area (241) of the evaporator to rapidly supply hot air from the beginning of the drying cycle, and increasing the cross-sectional area of ​​the condenser (242) to supply high-temperature hot air in the middle and end of the drying cycle.

[0359] However, if the area of ​​the evaporator and the condenser is increased excessively, a problem may arise in which the volume of the drying module (20) is excessively increased.

[0360] In addition, if the area of ​​the evaporator is increased, it may initially help heat the compressor (243), but if the compressor (243) is operating normally, an excessive amount of heat may be supplied to the compressor (243), which may cause the compressor (243) to overheat.

[0361] In addition, if the area of ​​the condenser is increased, it may help to quickly supply sufficient hot air at the beginning of the drying process, but if the compressor (243) operates normally, excessive heat may be supplied to the inside of the drum (150), which may damage clothing, and the temperature may uniformly rise throughout the circulating flow path, which may cause a problem of a decrease in the coefficient of performance.

[0362] To this end, the clothing treatment device of the present invention additionally arranges the auxiliary heat exchanger (245) and the switching valve (246), so that the auxiliary heat exchanger (245) can be converted into an evaporator (241) and a condenser (242) as needed.

[0363] For example, at the beginning of the drying process, the control panel (280) can control the switching valve (246) to control the auxiliary heat exchanger (245) to be used as the evaporator (241). Specifically, the switching valve (246) can guide the refrigerant delivered from the condenser (242) to the expansion valve (244), and the refrigerant passing through the expansion valve (244) can pass through the auxiliary heat exchanger (245) and then flow into the evaporator (241).

[0364] In this process, the refrigerant absorbs heat from the outside air in the auxiliary heat exchanger (245) and then flows back into the evaporator (241) to absorb heat from the air flowing through the flow path forming part (220). As a result, the energy of the refrigerant flowing into the compressor (243) increases further, so that the time it takes for the compressor (243) to operate normally and increase the pressure of the refrigerant can be shortened.

[0365] When the compressor (243) operates normally, such as in the middle or end of the drying cycle, the control panel (280) can control the switching valve (246) to control the auxiliary heat exchanger (245) to be used as the condenser (242). Specifically, the switching valve (245) can guide the refrigerant delivered from the condenser (242) directly to the auxiliary heat exchanger (245), and the refrigerant that has passed through the auxiliary heat exchanger (245) can pass through the expansion valve (244) and then flow into the evaporator (241).

[0366] In this process, the refrigerant is heated by discharging heat from the condenser (242) to the air flowing through the flow path forming part (220), and then moves to the auxiliary heat exchanger (245) to discharge some of the remaining heat back to the outside air. As a result, the refrigerant can be introduced into the evaporator (241) with a sufficient temperature and pressure while passing through the expansion valve (244) in a state where the enthalpy has dropped significantly. As a result, the heat exchange part (240) can be prevented from overheating, and the temperature difference between the evaporator (241) and the condenser (242) can be secured to be larger, thereby preventing the coefficient of performance from decreasing.

[0367] Figure 20 illustrates an example of an air circulation method of the clothing treatment device of the present invention.

[0368] When the drying process of the clothing treatment device of the present invention is performed, the circulation fan (330) provided in the duct module (30) can be driven, and the compressor (243) of the drying module (20) can be driven.

[0369] When the above circulation fan (330) is driven, the air contained in the drum (150) can be discharged through the discharge hole (157) and can be introduced into the duct body (310) through the discharge port (1411).

[0370] The air flowing in through the duct body (310) can have foreign substances filtered out as it passes through the filter unit (350), and can pass through the circulation fan (330) and the fan receiving unit (320).

[0371] The air passing through the fan receiving portion (320) may be introduced into the inlet (215) provided in the case (210) of the drying module (20) and introduced into the flow path forming portion (220). The air supplied into the flow path forming portion (220) may be dehumidified and heated while sequentially passing through the evaporator (241) and the condenser (242) while rising to the outlet (216) located above the inlet (215). The air passing through the condenser (242) may be converted into high-temperature dry hot air and introduced into the drum (150) to dry clothes contained in the drum (150). The above-described process may be repeated until the drying cycle is completed.

[0372] However, in order for the above air circulation process to occur, it must be assumed that the hot air supplied to the drum (150) does not leak out of the cabinet (110). To this end, since the drum (150) is provided with an inlet hole (155) at the rear and an exhaust hole (154) at the front, it is necessary that the air introduced into the inlet hole (155) moves to the front of the drum (150) without being accumulated or dispersed, and that the air discharged from the exhaust hole (154) is guided as is into the duct body (310) without being leaked.

[0373] The clothing treatment device of the present invention is provided inside the cabinet (110) and guides air introduced into the drying module (10) through the housing (140) that accommodates the drum (150) from the rear to the front of the drum (150) without accumulation or leakage, and can supply the air guided to the front of the drum (150) as is into the duct body (310).

[0374] Figure 21 illustrates a specific structural example of the housing.

[0375] Referring to Fig. 21(a), the housing (140) may be provided to extend from the front panel (111) of the cabinet (110) to the rear panel (114).

[0376] The housing (140) may be provided to extend from the rear panel (114) to the front panel (111) and guide air introduced from the rear panel (114) to the front panel (111).

[0377] The above housing (140) may be equipped with a duct that guides the hot air supplied from the drying module to the front panel (111) without leaking out to the upper panel (117) or side panel (113) of the cabinet (110), and may completely accommodate the drum (150) inside.

[0378] When the drum (150) is accommodated in the housing (140), it can be prevented from being exposed to the outside before the door (120) is opened.

[0379] The front-back length of the housing (140) may correspond to a first length (L1), which is a gap between the front panel (111) and the rear panel (114). The rear of the housing (140) may be in contact with the rear panel (114), and the front of the housing (140) may be in contact with the front panel (111). As a result, air flowing into the interior of the housing (140) may be prevented from leaking out to the front panel (111) and the rear panel (114).

[0380] Since the housing (140) is provided to connect the rear panel (114) and the front panel (111), the housing (140) can form an area where the driving unit (160) is mounted on the upper plate (143). Accordingly, the clothing treatment device of the present invention can place the driving unit (160) that rotates the drum (150) in the drying body (10) above the drum (150).

[0381] Since the housing (140) accommodates the entire drum (150), the entire inner surface of the housing (140) can be arranged to face the entire outer surface of the drum body (151). Accordingly, the driving unit (160) can be mounted on the housing (140) and the belt (162) can be freely connected between the front and rear of the drum body (151). Accordingly, not only can the belt (162) be wound around the drum body (151), but the driving unit (160) can also be mounted on the upper portion of the housing (140). Accordingly, the sealing force of the duct module (30) and the drying module (10) can be strengthened.

[0382] Referring to Fig. 21(b), the rear panel (114) may be formed with an inlet hole (1141) that is connected to the outlet (216) and receives hot air supplied from the drying module (20). The rear panel (114) may be arranged at the front of the case (210), so that the inlet hole (1141) may be in close contact with the outlet (216).

[0383] The front surface of the rear panel (114) and the case (210) can be arranged in surface contact with each other.

[0384] The area of ​​the above-mentioned injection hole (1141) is provided to be larger than the area of ​​the above-mentioned outlet (216), so that the hot air discharged from the above-mentioned outlet (216) can be guided directly into the above-mentioned injection hole (1141).

[0385] The above-mentioned injection hole (1141) and the inlet hole (155) of the drum may be positioned facing each other. The area of ​​the inlet hole (155) of the drum may be provided to be larger than the area of ​​the injection hole (1141), so that air flowing in from the injection hole (1141) may flow into the inlet hole (155) of the drum.

[0386] The above outlet (216), the above injection hole (1141), and the above inflow hole (155) can be arranged to completely overlap in the front-back direction.

[0387] The above outlet (216) and the above injection hole (1141) may be positioned higher than the rear support member (172). As a result, the supplied hot air can be lifted upward from inside the drum (150) and supplied directly to the falling clothing.

[0388] Meanwhile, the rear body (152) of the drum may be positioned a certain distance forward from the rear panel (114) so ​​as not to interfere with the rear panel (114) during the rotation process, and the inlet hole (155) provided in the rear body (152) may also be positioned forward from the input hole (1141). As a result, at least a portion of the hot air supplied from the input hole (1141) may not be input into the inlet hole (155) and may move toward the radial outside of the rear body (152).

[0389] However, since the housing (140) is provided in the shape of a duct extending from the rear panel (114) to the front panel (111), even if the space between the rear body (152) and the rear panel (114) is not sealed at least partially, the air can be prevented from being trapped in the housing (140) and leaking out of the drying body (10).

[0390] That is, even if some of the hot air leaks out between the rear body (152) and the rear panel (114), the hot air is trapped in the housing (140) and guided back to the inlet hole (155), or moves to the front of the housing (140) and heats the drum body (151) while being introduced into the discharge hole (154) to dry the clothes.

[0391] Figure 22 illustrates the arrangement relationship between the housing and the drum.

[0392] The housing (140) may be provided so that the front is completely open, and both the width and height of the housing (140) may be provided to be larger than the diameter of the drum (150). Accordingly, the drum (150) may be inserted into the front of the housing (140) and coupled to the rear support member (172).

[0393] The front-back length of the drum (150) may be provided as a second length (L2) that is smaller than the first length (L1) that is the front-back length of the housing (140). The front of the housing (140) may be positioned forward of the inlet (1531) of the drum (150), and the rear of the housing (140) may be positioned rearward of the rear body of the drum (150). Hot air introduced from the rear of the housing (140) may be supplied to the entire drum (150).

[0394] The housing (140) may include a bottom surface (141) that is mounted on the duct module (30) and divides the inside of the duct module (30) and the drying body (10), a side plate (142) that extends upward from the bottom surface (141) to form both sides of the housing (140), and an upper plate (143) that is provided to connect the upper portions of the two side plates (142) to each other.

[0395] The above-mentioned bottom surface (141), the side plate (142), and the upper plate (143) may all be made of a metal material, and may all be provided with the same first length (L1) and may extend from the rear panel (114) to the front panel (111).

[0396] The above-mentioned bottom surface (141), the side plate (142), and the upper plate (143) are made of metal plates and can be joined to each other by surface contact through welding or a separate joining member, etc. As a result, the hot air supplied between the bottom surface (141), the side plate (142), and the upper plate (143) can be prevented from leaking out.

[0397] The rear plate (114) may be provided to shield the rear of the housing (140), and the front plate (111) may be provided to shield the front of the housing (140).

[0398] The above discharge port (1411) may be arranged closer to the front plate (111) than to the rear plate (114) on the bottom surface (141). The width of the discharge port (1411) may be formed to be larger than the diameter of the drum (150) so that a large amount of hot air can be smoothly introduced into the duct body (310).

[0399] The above discharge hole (154) may be arranged closer to the front than the rear of the drum body (151), and may be arranged so that at least a portion thereof faces the discharge port (1411) in the height direction. Thus, the drum (150) itself may form a path through which the hot air moves and is discharged.

[0400] In addition, the front-back thickness of the discharge hole (154) may be formed to be half or greater than half of the drum body (151). Accordingly, even if a large amount of hot air is supplied into the drum (150), the hot air does not accumulate inside the drum body (151) and can be smoothly discharged through the discharge hole (154) and supplied to the discharge port (1411).

[0401] The above discharge hole (154) may be formed along the circumference of the drum body (151). Accordingly, even if a part of the discharge hole (154) is positioned at the lower part of the clothing and is shielded, the remaining part may be open so that all hot air may be discharged outside the drum body (151) and guided to the discharge port (1411).

[0402] As a result, the drum (150) itself can form a path that guides the hot air from the inlet hole (155) to the outlet hole (154) while accommodating clothes. Accordingly, the drying body (10) is arranged in front of the drum (150), so that an additional duct for guiding the hot air to the duct module (30) can be omitted, and the thickness of the drying body (10) in the front-to-back direction can be prevented from being excessively increased. In addition, the length of the drum (150) can be secured as long as possible between the front panel (111) and the rear panel (114), so that a drying capacity suitable for a commercial dryer can be secured.

[0403] Meanwhile, the discharge hole (154) may be formed from the front of the drum body (151) so that the hot air can be guided to the front end of the drum body (151). In addition, the thickness of the discharge hole (154) in the front-back direction may be longer than the thickness of the discharge port (1411) in the front-back direction. At least a portion of the discharge hole (154) is arranged rearward of the discharge port (1411), so that even if the flow rate of the hot air supplied to the drum body (151) is large, it can be guided to be smoothly discharged through the discharge hole (154). Therefore, even if bedding or a large amount of clothing is accommodated, the hot air can be smoothly introduced and discharged into the drum body (151).

[0404] The above discharge port (1411) is positioned forward of the discharge hole (154) so ​​that the hot air can move as far as possible to the front of the drum body (151) and then flow into the duct module (30).

[0405] Meanwhile, the rear sealer (182) is coupled to the rear body (152) of the drum to prevent air flowing in from the inlet hole (1411) from leaking out of the drum (150) as much as possible.

[0406] Alternatively, the sealing portion (180) of the drying body (10) of the present invention may further include an additional sealer (183) that is coupled to the rear panel (114) to prevent air flowing in from the injection hole (1411) from leaking out of the rear body (152).

[0407] The above rear sealer (182) is provided in a ring shape and can be coupled to the rear body (152) of the drum to surround the inlet hole (155).

[0408] The additional sealer (183) may be coupled to the rear panel (114) so ​​as to be in contact with the inner or outer surface of the rear sealer (182). The additional sealer (183) may be provided to surround the insertion hole (1141).

[0409] The above additional sealer (183) can be arranged along the periphery of the rear body (152) of the drum or the rear sealer (182).

[0410] The above additional sealer (183) may be provided in a ring shape as a whole, or may be provided in multiple pieces with some sections, and may be arranged along the periphery of the rear body (152) of the drum or the rear sealer (182).

[0411] The above additional sealer (183) is provided so as to be in contact with the inner or outer surface of the rear sealer (182) to form a path through which hot air moves between the rear body (152) and the rear panel (114).

[0412] For example, the additional sealer (183) may be provided so as to be in contact with the inner surface of the rear sealer (182), thereby preventing the rear sealer (182) from rolling inward.

[0413] The above additional sealer (183) may be made of an elastic material, or may be made of a material such as felt so as not to impede the rotation of the drum (150).

[0414] The air introduced through the above-mentioned injection hole (1411) can be first sealed by the rear sealer (182) and the additional sealer (183) and then introduced into the drum body (151), and secondarily sealed by the housing (140) to prevent it from leaking out of the cabinet (110).

[0415] Alternatively, the rear sealer (182) may be fixed to an additional sealer (183) coupled to the inner surface of the rear panel (114) and arranged along the perimeter of the rear body (152) of the drum. That is, the rear sealer (182) may not be fixed to the drum (150), but may be supported by the fixed rear panel (114).

[0416] The additional sealer (183) may be provided with a harder structure than the rear sealer (182), such as a metal material or resin series. The additional sealer (183) may be provided to be arranged along the outer circumference of the inlet hole (155) and to be coupled with the rear sealer (182).

[0417] In this way, it is possible to prevent air flowing in through the injection hole (1411) from leaking out of the drum (150) as much as possible.

[0418] The above additional sealer (183) may include a joining portion that is joined to the rear panel (114), and a fixing portion that is bent radially outward from the joining portion and to which the rear sealer (182) is joined. At this time, the additional sealers (183) may be provided in multiple pieces and arranged in a curved shape, and may be arranged spaced apart from each other along the outer circumference of the inlet hole (155). As a result, the fixing portion can be bent as uniformly as possible at the joining portion.

[0419] Meanwhile, since the housing (140) is provided to accommodate the entire outer surface of the drum (150), it may further include a cut portion (146) provided to connect the driving unit (160) and the drum (150). The cut portion (146) may be provided to communicate between the motor (161) disposed outside the housing (140) and the drum body (151) disposed inside the housing (140).

[0420] For example, the cut portion (146) can form a space in the housing (140) through which the belt (162) passes.

[0421] The above-mentioned cut portion (146) may be formed by penetrating the upper plate (143) of the housing. In addition, the cut portion (146) may be positioned closer to the rear panel (114) than the front panel (111). Accordingly, the cut portion (146) may be positioned closer to the discharge hole (1141) and in a direction perpendicular to the direction of movement of the hot air, thereby preventing the hot air discharged from the discharge hole (1141) from flowing out toward the cut portion (146).

[0422] The housing (140) may further include a shielding case that accommodates at least a portion of the driving unit (160) including the belt (162) and is coupled to the cut-out (146) to seal the cut-out (146).

[0423] The sealing portion (180) may be provided to seal between the housing (140) and the rear panel (114). For example, the sealing portion (180) may be provided in a shape corresponding to the front sealer (181) and may further include an additional sealer that seals between the housing (140) and the rear panel (114).

[0424] Meanwhile, since the rear panel (114) is configured to have the rear support member (172) and the drying module (20) installed thereon and is also in close contact with the rear panel (114), it is necessary to be very firmly fixed. Accordingly, the rear panel (114) can be fixed by being coupled to the housing (140).

[0425] For example, the rear end of the housing (140) may be joined to the front end of the rear panel (114) by welding or the like. Alternatively, a separate joining member, such as a hinge structure, may be provided to join the rear end of the housing (140) and the front end of the rear panel (114). The joining member may be provided to join the entire edge of the rear end of the housing (140) and the front end of the rear panel (114).

[0426] Accordingly, the entire rear end surface of the housing (140) can be completely in close contact with the rear panel (114), and the area of ​​the front surface of the rear panel (114) that comes into contact with the rear end surface of the housing (140) can be completely in close contact with the rear end surface of the housing (140).

[0427] As a result, the rear panel (114) is fixed to the housing (140) so as to not only distribute the load of the drum (150), but also fundamentally block the hot air supplied into the housing (140) from leaking between the rear panel (114) and the housing (140).

[0428] Figure 23 illustrates the relationship between the position of the driving unit and the shape of the housing of the clothing treatment device of the present invention, and Figure 24 illustrates the degree of freedom of change in the shape of the housing according to the position of the driving unit.

[0429] Referring to Fig. 23, in general, commercial dryers are equipped with a large-capacity drum (150) and a large-capacity laundry is loaded inside in a wet state, so a high-power drive unit (160) is provided. Therefore, since the weight and volume of the drive unit (160) are large, in order to stably support the drive unit (160), commercial dryers generally place the drive unit (160) in area B, which is lower than the drying body (10). For example, the drive unit (160) may be placed in the duct module (30) or may be placed so as to overlap in the front-back direction at the rear of the duct module (30).

[0430] However, if the driving unit (160) is placed in the B area, the stability of the entire clothing treatment device increases, but the distance between the driving unit (160) and the drum (150) cannot but become further apart.

[0431] As the gap between the driving unit (160) and the drum (150) increases, the distance between the outer surface of the drum (150) and the belt (162) connecting the driving unit (160) also inevitably increases.

[0432] In this state, when the housing (140) that accommodates the drum (150) is placed, the housing (140) has no choice but to set the width of the cut portion (146) to a first width (D1) that is larger than the radius of the drum (150) so that the belt (162) can move without interference.

[0433] If the housing (140) is already provided with an outlet (1411) and an area corresponding to the width of the first width (D1) and the thickness of the belt up to the cut portion (146), it is difficult to install a shielding case that shields the cut portion (146), and thus it may be impossible to maintain the airtightness of the housing (140).

[0434] Accordingly, when the driving unit (160) is placed in the B area in a commercial dryer, the housing (140) can be designed to avoid the area where the belt (162) is placed. Accordingly, the housing (140) can be placed only in the area that shields the discharge hole (154), and can be installed so as to avoid the area where the driving unit (160) is placed.

[0435] In this case, since the discharge hole (154) is positioned at the front of the drum, the housing (140) is provided to accommodate only the front of the drum (150) and guide the air discharged from the discharge hole (154) to the duct module (30), and the rear of the drum (150) becomes the area where the belt (162) is wound, and thus cannot help but be exposed to the outside of the housing (140). Therefore, a fundamental problem arises in that the housing (140) cannot extend to the rear panel (114) even if it is in close contact with the front panel (113).

[0436] In addition, since the housing (140) cannot seal the rear panel (114), the commercial dryer must have a problem in that the sealing portion (180) must be provided to seal the entire area between the back surface of the drum (150) and the input hole (1141), and between the inner surface of the housing (140) and the exposed surface of the drum body (151) so that the air discharged from the input hole (1141) does not leak out of the drum (150).

[0437] However, since the rear body (150) that is provided to rotate cannot be in close contact with the rear panel (114) that is stationary, even if a sealing part (180) is provided between the rear body (150) and the injection hole (1141), the hot air cannot help but leak out of the drum (150).

[0438] Referring to Fig. 24(a), since the exposed surface between the housing (140) and the drum body (151) must also be sealed, the shape of the housing (140) must also be cylindrical like the drum body (151). In particular, since the narrower the space between the inner surface of the housing (140) and the outer surface of the drum body (151), the better the sealing, the diameter of the housing (140) must be limited to the diameter of the drum (150).

[0439] For example, if the diameter of the drum (150) is provided as a first diameter (R1), the diameter of the housing (140) may be provided as a second diameter (R2) that is not significantly different from the first diameter (R1). The second diameter (R2) may be set to be significantly smaller than the width of the front panel (111).

[0440] Accordingly, even if the housing (140) is formed of the metal material to be cylindrical, it must be formed to be relatively thin, making it difficult to secure sufficient rigidity. As a result, it may be impossible to provide the housing (140) with an external surface capable of supporting or installing additional components such as a driving unit.

[0441] And, since the gap between the inner surface of the housing (140) and the drum (150) vibrates up and down and changes constantly, the sealing member (180) must be provided so as to be coupled to the outer surface of the drum body (151) and seal the inner surface of the housing (140). However, since the drum body (151) is configured to vibrate while rotating, even if the sealing member (180) is provided, hot air cannot help but leak between the inner surface of the housing (140) and the exposed surface of the drum body (151). Therefore, a commercial dryer in which the driving member (160) is placed in area B cannot help but experience a loss of hot air, and the drying efficiency cannot help but drop.

[0442] Referring again to Figure 23, in order to overcome these problems, the garment treatment device of the present invention is provided so that the driving unit (160) is installed in area A inside the drying body (10). As a result, the garment treatment device of the present invention can overcome most of the disadvantages of commercial dryers in which the driving unit (160) is installed in area B.

[0443] Specifically, the garment treatment device of the present invention can also reduce the gap between the driving unit (160) and the drum (150), so that the gap of the belt (162) connecting the driving unit (160) and the outer surface of the drum (150) can also be reduced. Accordingly, the width of the cut portion (146) in the housing (140) can be provided as a second width (D2) smaller than the first width (D1), and the second width (D2) can be set smaller than the radius of the drum (150). Accordingly, even if the cut portion (146) having the second width (D2) is provided in the housing (140), the airtight performance inside the housing (140) can be sufficiently maintained.

[0444] Therefore, the housing (140) may be provided to accommodate the drum (150) including the area where the belt (162) is placed. As a result, the housing (140) may be designed to extend completely from the front panel (111) to the rear panel (114).

[0445] Accordingly, since the back surface of the housing (140) is in close contact with the rear panel (114), even if the rear panel (114) and the rear body (152) are not completely sealed, the hot air can be prevented from leaking out of the housing (140).

[0446] Referring to Fig. 24(b), since the housing (140) can seal the front panel (111) and the rear panel (114) itself independently of the drum (150), the housing (140) can be expanded in diameter, etc., regardless of the diameter of the drum body (151). For example, even if the housing (140) is provided in a cylindrical shape, it can be provided with a third diameter (R3) that is much larger than the diameter (R1) of the drum (150). The third diameter can correspond to the width of the front panel (111). (Shape I)

[0447] However, since the housing (140) is provided to seal the inside of the cabinet (110), it does not need to be provided to seal the outer surface of the drum body (151).

[0448] Accordingly, the housing (140) of the garment treatment device of the present invention may be provided in a shape unrelated to the shape of the drum body (151). As a result, the housing (140) may be provided in an expanded polygonal shape with a width and height equal to a third diameter (R3). (Second shape)

[0449] Meanwhile, the housing (140) of the garment treatment device of the present invention may be manufactured by combining flat metal plates, and the thickness of the metal plates may be manufactured to be sufficient to secure and support the driving unit (160). Accordingly, the housing (140) of the garment treatment device of the present invention may be provided to secure the driving unit (160) on the upper portion. The housing (140) may allow only the belt (162) to pass through the inside of the housing (140) through the cut portion (146) having the second width (D2).

[0450] Accordingly, the housing (140) may be designed to have a height from the bottom surface to the upper surface lower than the third diameter (R3) so that the upper surface is spaced apart from the upper panel (117) of the cabinet (110) to secure a space for installing the driving unit (160). (Third shape)

[0451] For example, the upper plate (143) of the housing (140) may be designed in a trapezoidal shape. The upper plate (143) may include an extension plate (1432) spaced apart from the upper panel (117) of the cabinet (110) downwardly, and an inclined plate (1431) extending from both ends of the extension plate (1432) to the side plate (142) so as to be lowered in height. A space in which the driving unit (160) is arranged may be formed between the upper panel (114) and the upper plate (143) of the housing (140).

[0452] The above driving unit (160) can be supported on the inclined plate (1431).

[0453] Figure 25 illustrates an example of sealing the housing of the garment treatment device of the present invention.

[0454] The front sealer (181) may be coupled to at least one of the cabinet (110) and the housing (140). The front sealer (181) may be provided to seal between the front surface of the housing (140) and the inner surface of the front panel (111).

[0455] The front sealer (181) may be coupled along the perimeter of the front surface of the housing (140). The front sealer (181) may be provided as an elastic member that is coupled and fixed to the end of the front surface of the housing (140).

[0456] The above front sealer (181) may be provided so as to be in contact with or in close contact with the inner surface of the front panel (111) while being fixed to the housing (140).

[0457] The above front sealer (181) is provided to be fixed to a stationary housing (140). Therefore, the front sealer (181) can exhibit higher sealing performance than the rear sealer (182) coupled to a moving object such as a drum.

[0458] Meanwhile, the front sealer (181) may be provided in a polygonal shape coupled along the front surface of the housing (140). Accordingly, the area of ​​the front sealer (181) may be provided to be larger than the diameter of the drum (150) and the diameter of the opening (1111). Accordingly, the front sealer (181) may be arranged outside the opening (1111) and the drum (150).

[0459] In addition, the front support member (171) and the hinge joint member (130) are coupled and fixed to the inside of the housing (140). Therefore, the support member (170) and the hinge joint member (130), etc., may be arranged inside the front sealer (181).

[0460] Since the above duct module (30) is configured to be placed outside the housing (140), the above duct module (30) can be placed outside the front sealer (181).

[0461] The hot air can be prevented from leaking between the outside of the housing (140) and the inside of the cabinet (110) due to the above front sealer (181).

[0462] Specifically, the front sealer (181) may include a bottom sealer (1811) that is coupled to the front of the bottom surface (141) and adheres to the front panel (111), a side sealer (1812) that extends upward from both ends of the bottom sealer (1811) and is coupled to the front of the side plate (142) and adheres to the front panel (111), and an upper sealer (1813) that connects the upper ends of the side sealers (1812) that are arranged on both sides. The upper sealer (1813) may have a shape corresponding to the shape of the upper plate (143) of the housing (140).

[0463] The above front support member (171) can be placed between the bottom sealer (1811), the side sealer (1812), and the outer surface of the drum (150).

[0464] The above hinge joint (130) can be placed between the inside of the side sealer (1812) and the outer surface of the drum (150).

[0465] The front panel (111) above can have a contact area (C) where the front sealer (182) is in contact.

[0466] The above opening (1111) can be placed inside the contact area (C). Thus, the opening (1111) can be placed inside the front sealer (181).

[0467] The front panel (111) may include a recessed surface (1112) disposed on the outer surface of the opening (1111) and recessed toward the drum (150). The recessed surface (1112) may be provided in a shape corresponding to the inner frame of the door (120). The opening (1111) may be provided to penetrate the recessed surface (1112).

[0468] The above-mentioned sunken surface (1112) can be placed inside the above-mentioned contact area (C). Thus, the above-mentioned sunken surface (1112) can be placed inside the above-mentioned front sealer (181).

[0469] A sensor unit (400) for detecting the state inside the drum (150) may be installed on the back surface of the above-mentioned sunken surface (1112). The sensor unit (400) may be positioned inside the contact area (C). The sensor unit (400) may be positioned inside the front sealer (181).

[0470] Accordingly, the front sealer (181) can transmit the hot air to the sensor unit (400). As a result, the sensor unit (400) can detect the state inside the drum (150) without difficulty.

[0471] The sensor unit (400) may include a first sensor (410) capable of detecting the temperature inside the drum (150) and a second sensor (420) capable of detecting the dryness of the clothing. The first sensor (410) and the second sensor (420) may be placed inside the front sealer (181).

[0472] Meanwhile, the control panel (190) may be positioned above the opening (1111). The control panel (190) may be positioned outside the contact area (C) and the front sealer (181). As a result, the hot air supplied inside the housing (140) may be blocked from approaching the control panel (190), and the control panel (190) may be prevented from overheating.

[0473] Figure 26 illustrates the arrangement relationship between the front sealer and other components.

[0474] The door (120) is positioned forward of the front panel (111) and is provided to open and close the opening (111), and the drum (150) is positioned rearward of the door (120) and the front panel (111).

[0475] The housing (140) is provided to accommodate the drum (150), and the front end can be extended from the rear panel (114) and positioned forward of the front body (151) corresponding to the front of the drum (150).

[0476] The side panel (113) or upper panel (117) may be placed outside the housing (140), but the front end may be placed behind the front end of the housing (140).

[0477] The front panel (111) may include a front plate (111a) in which an opening (1111) is formed, and a bending frame (111b) that is bent rearward at at least one of the corners of the front plate (111a) and can come into contact with at least one of the front end of the upper panel (117), the front end of the side panel (113), and the front end of the bottom surface (141).

[0478] The front plate (111a) may be positioned forward of the front body (153), and the rear end of the bending frame (111b) may be positioned backward of the front body (153) or the front end of the housing (140).

[0479] The hinge joint (130) may be arranged so that the rear end can be joined to the inner wall of the housing (140), and the front end protrudes forward from the front end of the housing (140).

[0480] The front of the above hinge joint (130) can be accommodated in the above folding frame (111b) and can be in contact with the back surface of the front plate (111a).

[0481] The above front sealer (181) can be coupled to the front end of the housing (140) and positioned to protrude forward from the housing (140).

[0482] The front of the front sealer (181) may be positioned further forward than the front of the hinge joint (130) before being pressed against the front plate (111a). As a result, the performance of the front sealer (181) sealing the front panel (111) and the housing (140) can be guaranteed.

[0483] The above front sealer (181) may include a joining end (181b) that is joined to the front end of the housing (140), and a sealing end (181a) that extends forward from the joining end and contacts the front panel (111).

[0484] The above-mentioned connecting member (181b) may be provided to accommodate the front end of the housing (140). The front end of the housing (140) may be inserted into the connecting member (181b).

[0485] The above-mentioned connecting member (181b) may be provided to support both the outer surface and the inner surface of the housing (140). This can prevent the installation position of the front sealer (181) from changing.

[0486] The above sealing member (181a) may be provided with a closed curve in cross-section. Accordingly, the sealing member (181a) may be provided to enable compression to a certain length and may have restoring force. The sealing member (181a) may be pressed against the front plate (111a).

[0487] The sealing member (181a) may be positioned forward of the front body (153), the hinge joint (130), and the housing (140). Accordingly, when the front panel (111) is mounted in front of the housing (140), the sealing member (181a) may be pressed against the back surface of the front panel (111). For example, the sealing member (181a) may be pressed against the front plate (111a). Accordingly, even if the gap between the front panel (111) and the housing (140) is not uniform due to tolerance, the front sealer (181) may completely seal the entire contact area (c).

[0488] The front end of the hinge joint (130) may be positioned to protrude further forward than the front end of the housing (140). As a result, at least one of the door (120) and the front panel (111) may be coupled to the hinge joint (130) without interference with the housing (140).

[0489] The present invention may be implemented in various modified forms, and the scope of the invention is not limited to the above-described embodiments. Therefore, if a modified embodiment includes elements of the claims of the present invention, it should be considered to fall within the scope of the present invention.
