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] These commercial dryers, like home dryers, utilize a heat pump system that includes a compressor to compress refrigerant and heat the air supplied to the drum to dry clothes. However, since these compressors are made of metal, they tend to absorb heat from the heated refrigerant during the initial operation of the compressor, hindering the increase in the temperature of the refrigerant. In particular, if a commercial dryer uses a compressor with a larger capacity or output than that used in home dryers to dry large quantities of clothes, the compressor itself may take longer to heat up to a point where it cannot absorb the heat from the refrigerant, which may further delay the compressor from operating at normal RPM.

[0006] Therefore, conventional commercial dryers had a problem in that the drying process took longer than that of household dryers to normalize, which made the drying process unnecessarily long.

[0007] In particular, in the case of commercial dryers, there was a problem of the entire drying process being delayed because it took a long time for the drying process to normalize due to the nature of having to dry large quantities of clothes.

[0008] Furthermore, conventional commercial dryers had a problem in that the refrigerant was forcibly compressed when the compressor was not sufficiently heated at the beginning of the compressor operation, making it difficult to ensure the durability of the compressor.

[0009] The present invention aims to solve the problem of providing a clothes treatment device capable of rapidly increasing the temperature of a compressor in a commercial dryer using a heat pump.

[0010] The present invention aims to provide a clothes treatment device capable of rapidly increasing the temperature of a refrigerant by increasing the temperature of a compressor from the initial operation of the compressor.

[0011] The present invention aims to provide a clothing treatment device capable of preventing delay in the drying process by rapidly increasing the RPM of the compressor from the initial operation of the compressor to the normal RPM at which the compressor can perform the drying process.

[0012] In order to solve the above-described problem, the present invention provides a clothes treatment device capable of heating a compressor that compresses a refrigerant with a configuration other than the refrigerant.

[0013] For example, the present invention can heat the compressor with the electrical energy required to drive the compressor.

[0014] In order to solve the above-described problem, the present invention provides a clothes treatment device including a drying body including a cabinet forming an exterior and a drum disposed inside the cabinet for accommodating clothes; a drying module including a case provided to communicate with the cabinet, a flow path forming part disposed inside the case for forming a flow path for guiding air discharged from the drum back to the drum, a heat exchanger disposed inside the flow path forming part for heating the air, and a compressor disposed outside the flow path forming part for supplying a refrigerant for heat exchange with the air to the heat exchanger.

[0015] The compressor may include a casing mounted in the case, a compression unit disposed inside the casing to compress the refrigerant, and a driving unit connected to the compression unit and supplied with current to drive the compression unit.

[0016] The above driving unit can be controlled to block driving of the compression unit for a set period of time even when the above power is supplied.

[0017] The above driving unit may be provided to heat the inside of the casing with the current supplied for the above set time.

[0018] The driving unit may include a stator fixed in the casing and separated from the compression unit, a coil wound around the stator and supplied with current to generate a rotating magnetic field, a rotor disposed inside the stator and rotated by the rotating magnetic field, and a rotating shaft coupled to the rotor and coupled to the compression unit.

[0019] The above-mentioned rotating shaft can be maintained in a stopped state for a set period of time or longer after current is supplied to the coil.

[0020] The coil may include a single-phase coil provided to supply a single-phase current to the stator, a two-phase coil provided to be spaced apart from the single-phase coil so that the stator supplies a two-phase current having a phase difference of 120 degrees from the single-phase current, and a three-phase coil provided to be spaced apart from the single-phase coil and the two-phase coil so that the stator generates a three-phase current having a phase difference of 240 degrees from the single-phase current.

[0021] Current may be supplied to at least one of the 1-phase coil, the 2-phase coil, and the 3-phase coil, but the current may be controlled to be blocked from being supplied to all of the 1-phase coil, the 2-phase coil, and the 3-phase coil.

[0022] Only one of the above-mentioned 1-phase coil, 2-phase coil, and 3-phase coil can be controlled so that current is supplied for the above-mentioned set time.

[0023] The above setting time can be set to 3 minutes or more.

[0024] The above compressor may be provided to stepwise increase the frequency at which the compression unit operates when the compression unit begins to operate.

[0025] The drying apparatus may further include a control panel provided in either the drying body or the drying module, which provides a command to drive the compressor to perform a drying cycle for drying the clothes.

[0026] The above drying process may include a preheating step in which the driving RPM of the compressor is increased to the maximum RPM; a constant rate step in which the temperature inside the drum is increased to a target temperature after the preheating step; and a deceleration step in which the temperature inside the drum is increased to a limit temperature after the constant rate step.

[0027] The above driving unit can be controlled to block driving the compression unit for the set time when the preheating step starts.

[0028] The compressor further includes a heating wire wound around the outside of the casing to heat the casing, and the heating wire can be controlled to supply current for the set time.

[0029] The above driving unit can be controlled so that the current supply is cut off while current is supplied to the heating wire.

[0030] The above heating wire may include a compression wire wound in an area facing the compression section on the outer surface of the casing.

[0031] The above heating wire may include a driving wire wound in an area facing the driving unit on the outer surface of the casing.

[0032] The above heating wire may include a central wire wound in an area facing between the driving unit and the compression unit on the outer surface of the casing.

[0033] In order to solve the above-described problem, the present invention provides a control method including a drying module including a cabinet forming an exterior and a drum disposed inside the cabinet to accommodate clothes; a case provided to communicate with the cabinet; a flow path forming part disposed inside the case to form a flow path for guiding air discharged from the drum back to the drum; a heat exchanger disposed inside the flow path forming part to heat the air; and a compressor disposed outside the flow path forming part to supply a refrigerant for heat exchange with the air to the heat exchanger.

[0034] The above control method may include a preheating step of supplying current to the compressor to heat the compressor, and a driving step of driving the compressor to compress the refrigerant.

[0035] The above preheating step may prevent the refrigerant from being compressed.

[0036] The above drying module further includes a temperature sensor that detects the temperature inside the compressor or the temperature of the refrigerant, and when the temperature inside the compressor or the temperature of the refrigerant reaches a target temperature, the preheating step may be terminated and the driving step may be started.

[0037] The present invention has the effect of providing a clothes treatment device capable of rapidly increasing the temperature of a compressor in a commercial dryer using a heat pump.

[0038] The present invention has the effect of rapidly increasing the temperature of the refrigerant by increasing the temperature of the compressor from the beginning of compressor operation.

[0039] The present invention has the effect of preventing delay in the drying process by allowing the compressor to quickly increase from the initial operation of the compressor to the normal RPM at which the compressor can perform the drying process.

[0062] 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.

[0063] Figure 1 illustrates one embodiment of the clothing treatment device of the present invention.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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).

[0074] 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).

[0075] 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.

[0076] 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).

[0077] 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.

[0078] 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.

[0079] Figure 2 illustrates an embodiment in which the configuration of the garment treatment device of the present invention is provided in a detachable manner.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Figure 5 illustrates an embodiment of the internal structure of the clothing treatment device of the present invention.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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).

[0091] The above driving unit (160) can be placed in the drying body (10).

[0092] 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 component for the driving unit (160) to pass through or be installed, so that the sealing performance of the duct module (30) can be enhanced.

[0093] 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.

[0094] 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).

[0095] 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.

[0096] 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.

[0097] 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.

[0098]

[0099] 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.

[0100] The fan receiving portion (320) may be coupled to the duct body (310) or may be supported inside the duct body (310) to receive the circulation fan (330).

[0101] 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).

[0102] 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).

[0103] 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.

[0104] 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).

[0105] 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).

[0106] 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).

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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).

[0111] 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).

[0112] The above-mentioned euro-forming part (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 back surface of the drum (150).

[0113] Figure 4 illustrates an embodiment of the front configuration of the garment treatment device of the present invention.

[0114] The cabinet (110) forming the exterior of the above-mentioned drying body (10) may include a front panel (111) positioned in front of the drum (150), and side panels (113) extending rearward from both sides of the front panel (111).

[0115] 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).

[0116] 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).

[0117] 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).

[0118] The front panel (111) above may be provided with a height longer than its width.

[0119] 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.

[0120] 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.

[0121] 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) disposed inside the cabinet (100) to open and close the opening (1111).

[0122] Figure 5 illustrates an embodiment of the door structure of the garment treatment device of the present invention.

[0123] Referring to FIG. 5(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 portion (125) that is arranged between the inner frame and the outer frame and rotates the door (120) relative to the cabinet (110).

[0124] The inner frame (122) may include a sealing portion (124) that adheres closely to the inner surface of the opening (1111) to prevent hot air from leaking out of the opening (1111). The sealing portion (124) may be provided in a shape corresponding to the opening (1111).

[0125] 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.

[0126] The inner frame (122) may be provided with a protrusion on the inner surface to be inserted at least partially into the inner surface of the opening (1111), and the sealing portion (124) may be provided with an elastic material that is combined to surround the circumference of the protrusion.

[0127] 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).

[0128] 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.

[0129] The above fixed part (126) and fastening part may be configured with a conventional hook and hook fastening part.

[0130] 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) and blocks the opening of the door (120). 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.

[0131] Referring to FIG. 5(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 contact the front panel (111) by penetrating the inner frame (122).

[0132] 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.

[0133] The above grounding protrusion (1212) and the above coupling protrusion (1213) may be provided in multiple numbers.

[0134] Figure 6 illustrates an embodiment of the front structure of the clothing treatment device of the present invention.

[0135] The front panel (111) may be provided with the opening (1111) penetrating through the front panel (1111), and the opening (1111) may be provided with a shape corresponding to the inner shape of the door (120).

[0136] The front panel (111) above 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).

[0137] 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).

[0138] 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.

[0139] The above cover panel (112) can be detachably provided on the front of the duct body (310) at the lower part of the front panel (111).

[0140] The cover panel (112) may be rotatably coupled at the lower portion to the lower portion of the duct body (310) or the floor 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.

[0141] 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.

[0142] The above filter unit (350) is provided to allow air to pass through and may be provided in a plate shape.

[0143] 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.

[0144] 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.

[0145] 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).

[0146] Figure 7 illustrates an embodiment of the internal configuration of the garment treatment device of the present invention viewed from the front.

[0147] 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).

[0148] The front panel (111) above can be fixed by being joined to the reinforcing frame (115).

[0149] 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).

[0150] The above drying body (10) may further include a housing (140) that is accommodated inside the cabinet (110) and accommodates the drum (150).

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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).

[0157] 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).

[0158] 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, so that a separate duct can be omitted from being formed in the front of the drum (150) or the front panel (111).

[0159] 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).

[0160] 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), the 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.

[0161] Specifically, the housing (140) can be placed between the cabinet (110) and the drum (150) to form a path through which air moves.

[0162] 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).

[0163] 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.

[0164] The housing (140) may be provided so that the rear can communicate with the drying module (20) and the front can be in contact with 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).

[0165] 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).

[0166] 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.

[0167] 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).

[0168] 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).

[0169] 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).

[0170] 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.

[0171] The above hinge joint (130) can be fixed by being joined to the housing (140).

[0172] 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.

[0173] 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).

[0174] Meanwhile, the housing (140) can support the driving unit (160) from the outside of the housing (140).

[0175] The above hinge joint (130) is fixed by being joined to the inner surface of the housing (140).

[0176] Accordingly, the hinge joint (130) is placed between the drum (150) and the housing (140).

[0177] 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.

[0178] 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.

[0179] 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).

[0180] 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).

[0181] Figure 8 illustrates an embodiment of the sealing structure of the clothing treatment device of the present invention.

[0182] 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).

[0183] 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).

[0184] Specifically, the sealing portion (180) may include the front sealer (181) coupled to the housing (140).

[0185] The above 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).

[0186] 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).

[0187] The above front sealer (181) may be provided so as to be in contact with the inner surface of the front panel (111).

[0188] The area of ​​the front surface of the housing (140) may be larger than the diameter of the drum (150) and the diameter of the opening (1111). Accordingly, the front sealer (181) may be positioned outside the opening (1111) and the drum (150).

[0189] In addition, since the housing (140) is a fixed configuration inside the cabinet (110), the front sealer (181) can be maintained in a fixed state when coupled to the housing (140). Accordingly, the front sealer (181) can exhibit higher sealing performance than when coupled to a moving object such as a drum.

[0190] Meanwhile, since the front sealer (181) is arranged along the front perimeter of the housing (140), the support member (170) and the hinge connection member (130) and other components can be arranged on the inside of the front sealer (181).

[0191] The above duct module (30) can be placed outside the front sealer (181).

[0192] Due to the above front sealer (181), the interior of the housing (140) is connected to the drying module (20) so that hot air can move, but the hot air can be prevented from leaking between the exterior of the housing (140) and the interior of the cabinet (110).

[0193] Figure 9 illustrates an example of the arrangement position of the driving unit of the clothing treatment device of the present invention.

[0194] 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).

[0195] 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).

[0196] 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).

[0197] 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.

[0198] 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).

[0199] 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).

[0200] 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.

[0201] 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.

[0202] The upper surface of the housing (140) can be spaced downward from the upper panel of the cabinet to secure a space in which the driving unit (160) can be installed.

[0203] 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.

[0204] 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).

[0205] The housing (140) may include an upper surface (143) that is positioned above the drum (150) and supports the driving unit (160).

[0206] The upper surface (143) may include an inclined surface (1431) that extends high from the side panel (113) of the cabinet (110) toward the upper portion of the drum (150).

[0207] The above-mentioned inclined surface (1431) is provided so that the height thereof 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).

[0208] Additionally, the upper surface (143) may include an extension surface (1432) that extends from the upper end of the inclined surface (1431) toward the upper portion of the drum (150) so as to maintain a height.

[0209] The above-mentioned inclined surface (1431) and the above-mentioned extended surface (1432) may be formed as flat plates without any curves. As a result, even if a portion having a different height is formed on the upper surface (143), the occurrence of an area where residual stress is concentrated can be prevented in advance.

[0210] Due to the above extension surface (1432), the inclined surface (1431) can be prevented from being extended excessively or the 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 are balanced.

[0211] The above-mentioned inclined surface (1431) may be provided to extend so as to have a lower height toward the side panel (113) from both ends of the above-mentioned extended surface (1432), and may be formed symmetrically with respect to the above-mentioned extended surface (1432).

[0212] 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 two side surfaces (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 surface (143) may be provided to connect the two side surfaces (142) to each other.

[0213] Figure 10 illustrates an example of the rear structure of the garment treatment device of the present invention.

[0214] The above drying module (10) may further include a rear support member (172) on the rear surface that rotatably supports the drum (150).

[0215] 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).

[0216] The above rear support member (172) can be fixed by being joined to the rear panel (114) forming the rear of the cabinet (110).

[0217] 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).

[0218] 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).

[0219] 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).

[0220] 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).

[0221] 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).

[0222] 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.

[0223] Figure 11 illustrates an embodiment of the drum structure of the garment treatment device of the present invention.

[0224] The above housing (140) may be provided in a case shape with the front open to accommodate the drum (150).

[0225] 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), two sides (142), and an upper surface (143).

[0226] 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).

[0227] 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.

[0228] 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).

[0229] The above drum (150) may include a drum body (151) having a cylindrical shape and providing a space for accommodating clothing.

[0230] 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).

[0231] 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.

[0232] 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 drum back surface that is coupled to the rear of the drum body (151) and fixed to the rear support member (172).

[0233] The above drum (150) may further include an exhaust hole (154) through which hot air can move by penetrating the drum body (151).

[0234] 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.

[0235] 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.

[0236] 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.

[0237] Figure 12 illustrates an embodiment of the rear drum structure of the garment treatment device of the present invention.

[0238] 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).

[0239] 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).

[0240] The above rear body (152) may be provided to face the outlet through which hot air is discharged from the drying module (20).

[0241] 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).

[0242] 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).

[0243] 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.

[0244] 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).

[0245] 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).

[0246] 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).

[0247] 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).

[0248] 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).

[0249] 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).

[0250] 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.

[0251] 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 supplied hot air to the inlet hole (155).

[0252] Figure 13 illustrates an embodiment of a duct module of the clothing treatment device of the present invention.

[0253] 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.

[0254] 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.

[0255] The above duct body (310) may be provided with a high-strength metal material to support the drying body (10).

[0256] 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).

[0257] 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.

[0258] 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).

[0259] 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.

[0260] 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).

[0261] 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).

[0262] Figure 14 illustrates an example of installing a circulation fan of the clothing treatment device of the present invention.

[0263] 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).

[0264] The above first body (311) can be supported by the filter unit (350) being installed thereon.

[0265] The above second body (312) may be provided to support the load of the fan receiving portion (320) and the circulation fan (330).

[0266] Referring to Fig. 14(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).

[0267] 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.

[0268] 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.

[0269] 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).

[0270] 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).

[0271] 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.

[0272] 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.

[0273] 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).

[0274] Referring to Fig. 14(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.

[0275] 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).

[0276] The above fan fixing part (340) may be made of a material with higher strength than the foam material.

[0277] 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).

[0278] 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).

[0279] 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.

[0280] 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).

[0281] Figure 15 illustrates an example of the appearance of a drying module (20).

[0282] Referring to Fig. 15(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).

[0283] 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).

[0284] Referring to Fig. 15(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 through which the case (210) and external air communicate. The flow path forming part (220) and the auxiliary flow path part (230) may be arranged to be separated from each other so that air therebetween does not move with each other.

[0285] 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.

[0286] 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.

[0287] The above-mentioned euro-forming portion (220) can be formed by extending in the height direction inside the case (210).

[0288] The above auxiliary flow path (230) can be placed on one side of the flow path forming part (220).

[0289] 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.

[0290] 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.

[0291] 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.

[0292] 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).

[0293] 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).

[0294] The above auxiliary panel (214) may have multiple penetration holes installed in the height direction so that it can communicate with the outside air.

[0295] Referring again to Fig. 15(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).

[0296] 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.

[0297] The above auxiliary panel (214) and the above rear panel (212) can form the back surface of the case.

[0298] 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).

[0299] 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).

[0300] Figure 16 illustrates an example of the internal configuration of the drying module.

[0301] Fig. 16(a) illustrates the internal configuration of the case (210) in the drying module from the rear, and Fig. 16(b) illustrates the internal configuration of the case (210) in the drying module from the front.

[0302] Referring to Fig. 16(a), the drying module (20) may include a heat exchange unit (240) that is installed inside the case (210) and dehumidifies and heats the air supplied from the duct module (30) to generate hot air.

[0303] 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).

[0304] 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).

[0305] 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).

[0306] 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).

[0307] 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).

[0308] 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).

[0309] 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).

[0310] 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).

[0311] 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).

[0312] 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.

[0313] Referring to Fig. 16(b), the front panel (219) forming the front of the flow path forming part (230) may be arranged in front of the flow path forming part (230) and spaced apart from the front of the auxiliary flow path part (230).

[0314] 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).

[0315] 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).

[0316] 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.

[0317] 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).

[0318] 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).

[0319] 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).

[0320] 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.

[0321] 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.

[0322] The above-mentioned dry cleaning 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).

[0323] 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.

[0324] 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).

[0325] The above water supply unit (260) may also use water condensed in the above evaporator (241).

[0326] Alternatively, the water supply unit (260) may be provided to supply water directly from an external water source to the cleaning unit (270).

[0327] 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).

[0328] The above control panel (280) may also be provided to control the water supply valve (261).

[0329] Figure 17 is a simplified diagram showing the structure in which the auxiliary heat exchanger (245) of the clothing treatment device of the present invention is installed.

[0330] Figure 17 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.

[0331] 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).

[0332] 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.

[0333] 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.

[0334] 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.

[0335] 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.

[0336] 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.

[0337] 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).

[0338] 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.

[0339] 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).

[0340] 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.

[0341] Figure 18 illustrates an embodiment of a compressor applied to the drying module of the clothing drying apparatus of the present invention.

[0342] The compressor (243) may include a casing (400) that is mounted on the auxiliary flow path (230) and placed outside the flow path forming part (220), a compression part (600) that is placed inside the casing (400) and compresses the refrigerant, and a driving part (500) that is connected to the compression part (600) and receives current to drive the compression part.

[0343] The above casing (400) may be provided in a cylindrical shape, and may include an inlet pipe (420) through which refrigerant is introduced from an evaporator (241), etc., and a discharge pipe (410) through which refrigerant compressed in the compression unit (600) is discharged, and may include a terminal (430) for supplying power to the driving unit (500).

[0344] The above casing (400) may be provided with a storage space in which oil for lubricating the compression unit (600), etc., is stored in an area opposite the discharge pipe (410).

[0345] The above terminal (430) may be connected to a control panel (190) or a control panel (280) to supply power or receive a control signal, and may be provided to transmit a three-phase current that controls the driving unit (500).

[0346] The compressor (243) of the present invention may additionally place an emulator (440) upstream of the inlet pipe (420) so that only liquid refrigerant can be introduced into the inlet pipe (420).

[0347] The above driving unit (500) may be equipped with a motor that provides power to drive the compression unit (600) to compress and vaporize the refrigerant.

[0348] For example, the driving unit (500) may include a stator (510) that is fixedly coupled to the casing (400), a rotor (520) that is rotatably provided inside the stator (510), and a driving shaft (530) that is coupled to the rotor (520) and extends to the compression unit (600).

[0349] The above driving unit (500) may further include a coil (540) that is connected to the terminal (440) and wound around the stator (510) to generate a rotating magnetic field (or rotating magnetic field). The coil (540) may be provided as a wire or the like that winds the stator (510) at the terminal (440).

[0350] The above rotor (520) may be equipped with permanent magnets coupled along its circumference so that it can rotate by the rotating magnetic field.

[0351] The compression unit (600) may include a main frame (610) that is fixed and coupled to the inside of the casing (400) and through which the drive shaft (530) passes or rotatably supports the drive shaft (530), a fixed frame (620) that is coupled to the main frame (610) and provides a space in which the refrigerant is compressed, and a compression frame (630) that is accommodated inside the main frame (610) and the fixed frame (620) and rotatably supports the drive shaft (530).

[0352] The above fixed frame (620) may be provided so as to be coupled with the inlet pipe (620) to receive refrigerant, and may form a compression space therein so that the compression frame (630) can rotate around the rotation axis.

[0353] The above main frame (610) may be coupled to the fixed frame (620) to shield the compressed space.

[0354] The compression unit (600) may be provided with a plurality of compression frames (630) to compress and discharge a large amount of refrigerant so that it can be used in a commercial dryer. In this case, the main frame (610) may be coupled to one surface of the fixed frame (620) facing the driving unit (500) and the other surface of the fixed frame (620) facing the storage space. The compression frame (630) may be accommodated between one surface of the fixed frame (620) and the main frame (610), and between the other surface of the fixed frame (620) and the main frame (610), to rotatably support the driving shaft (530).

[0355] Of course, the compression frame (630) may be provided in a single unit. In this case, the main frame (610) and the compression frame (630) positioned toward the storage space in the fixed frame (620) may be omitted.

[0356] The above driving shaft (530) may be provided such that the area supported by the compression frame (630) is eccentric in one of the diametric directions of the fixed frame (620). Accordingly, when the driving shaft (530) rotates, the eccentric area of ​​the driving shaft (530) presses the compression frame (630) toward the inner surface of the fixed frame (620), thereby compressing the refrigerant introduced from the inlet pipe (420).

[0357] The main frame (610) or the fixed frame (620) may include a discharge port for discharging the compressed refrigerant, and the refrigerant discharged through the discharge port may pass through the driving unit (500) and be discharged to the discharge pipe (410).

[0358] The compression unit (600) may be provided with any structure as long as it can compress the refrigerant. For example, the compression unit (600) may be provided with a scroll compressor, a rotary compressor, or a linear compressor. For example, when the compression unit (600) is provided with a scroll compressor, the fixed frame (620) may be provided with a fixed scroll having a scroll-shaped wrap, and the compression frame (630) may be provided with an orbiting scroll having an orbiting wrap that engages with the wrap of the fixed scroll.

[0359] When the compression unit (600) is equipped with a rotary compressor, the fixed frame (620) may be equipped with a housing that provides a space in which the refrigerant is compressed, and the compression frame (630) may be equipped with a rotary that sequentially contacts and rotates around the inner surface of the fixed frame (620).

[0360] Figure 19 illustrates an example of the internal structure of the motor unit.

[0361] The above stator (510) is fixed to the inner surface of the casing (400), and may include a plurality of stator bodies (511) arranged along the inner surface of the casing (4100), a winding surface (5111) extending inwardly from the stator body (511) so as to have a smaller thickness, on which a coil (540) is wound, and a teeth body (5112) arranged on the inner surface of the winding surface (5111) to face the rotor (520) and to fix the coil (540).

[0362] A main frame (610) may be provided at the lower portion of the stator body (511), and an axle member (611) that rotatably receives the driving shaft (530) may be provided at the center of the main frame (610). The stator body (511) may be arranged symmetrically along the circumference with respect to the axle member (611).

[0363] The motor unit (500) of the compressor (243) of the present invention may be provided to rotate the rotor (530) through a two-phase or three-phase current, etc.

[0364] The above stator body (511) can be provided with 6n, which is the least common multiple of 2 and 3, so as to sequentially supply two-phase current and three-phase current based on the rotor (530).

[0365] For example, the coil (540) may include a first phase coil (541) provided to supply a first phase current, a second phase coil (542) provided to supply a second phase current having a phase difference of 120 degrees from the first phase current, and a third phase coil (543) provided to supply a third phase current having a phase difference of 120 degrees from the first phase current. The first phase coil (541), the second phase coil (542), and the third phase coil (543) may be sequentially wound around a plurality of stator cores (511) arranged along the circumference of the casing (400), and depending on the number of the stator cores (511), the first phase coils (541), the second phase coils (542), and the third phase coils (543) may be provided in multiple numbers with the same number of coils.

[0366] Accordingly, when a current is generated in the coil (540), the rotor (520) can rotate as the permanent magnet reacts to the rotating magnetic field (or rotating magnetic field) formed by the phase difference of the current, thereby generating power to compress the refrigerant.

[0367] Meanwhile, the compression unit (600) can pressurize the liquid refrigerant supplied to the evaporator (241) to produce a high-temperature gaseous refrigerant. However, in the initial stage when the compression unit (600) begins to operate, the temperature of the compressor (243) itself is low, so even if the compression unit (600) compresses and heats the refrigerant, the temperature of the refrigerant may be delayed from rising to the target temperature.

[0368] In particular, since the casing (400), the compression unit (600), the drive unit (500), etc. are mostly made of metal, when the temperature is low at the beginning of the drying process, heat is absorbed from the refrigerant, which delays the heating of the refrigerant and thus delays the drying process and may also deteriorate the drying performance. In addition, a problem of liquid refrigerant being discharged from the compression unit (600) may also occur, which may weaken the durability of the compressor (243).

[0369] To solve this problem, the clothing treatment device of the present invention may be equipped to increase the internal temperature of the compressor (243) at the beginning of the drying cycle or when the internal temperature of the compressor (243) is lower than the normal temperature.

[0370] For example, the clothing treatment device of the present invention can use the current supplied to the coil (540) to increase the internal temperature of the compressor (243).

[0371] The rotor (520) can rotate only when current is supplied to all of the first phase coil (541), the second phase coil (542), and the third phase coil (543). That is, if the current is cut off to only one of the first phase coil (541), the second phase coil (542), and the third phase coil (543), the rotor (520) may not be able to rotate continuously.

[0372] Accordingly, the clothing treatment device of the present invention can control the supply of current to the driving unit (500) at the beginning of the drying cycle or when the internal temperature of the compressor (243) is lower than the set temperature, but block the supply of current to any one of the first phase coil (541), the second phase coil (542), and the third phase coil (543) for a set time.

[0373] Accordingly, the inside of the casing (400) can be heated by heating the coil (540) and the stator (511) through the current supplied to at least one of the first phase coil (541), the second phase coil (542), and the third phase coil (543). As a result, the temperature of the entire compressor (243) can be increased.

[0374] The above driving unit (500) can be controlled so that a rotating magnetic field is not formed for a set period of time even when current is supplied to the coil (540). As a result, rotation of the driving shaft (530) can be blocked, and driving of the compression unit (600) can be blocked.

[0375] Drive shaft (530) For example, the current supply may be cut off to only one of the first phase coil (541), the second phase coil (542), and the third phase coil (543), or the current may be supplied to only one of them. Of course, the current may be controlled to be supplied to the remaining ones except for one of the first phase coil (541), the second phase coil (542), and the third phase coil (543).

[0376] As a result, the current supply to the first phase coil (541), the second phase coil (542), and the third phase coil (543) can all be blocked during the set time.

[0377] When the current supply is cut off to only one of the first phase coil (541), the second phase coil (542), and the third phase coil (543), the compressor (243) can be heated more quickly than when the current is supplied to only one of the first phase coil (541), the second phase coil (542), and the third phase coil (543).

[0378] The garment treatment device of the present invention may set the set time to be long in order to sufficiently heat the compressor (243) using electric energy. The set temperature may be a temperature at which the refrigerant introduced into the compressor (243) is prevented from transferring heat to the compressor (243). For example, the set temperature may be set to a target temperature at which the refrigerant is compressed and discharged when the drying cycle is normalized, and the set time may be set to 3 minutes or more.

[0379] For example, the above setting time can be set to approximately 5 minutes.

[0380] As a result, the clothing treatment device of the present invention can heat the compressor (243) without rotating the drive shaft (530) through the current supplied to the coil (540) when the compressor (243) starts to heat up from a state where it has been cooled to room temperature, thereby heating the compressor (243) without driving the compression unit (600).

[0381] Thereafter, when the compressor (243) is heated to the set temperature, the control panel (280) can start to drive the compressor (243) by supplying current to all coils (540). In other words, the driving unit (500) can rotate the driving shaft (530) by supplying current to the coils (540) to form a rotating magnetic field after the set time.

[0382] Figure 20 illustrates another embodiment of heating the compressor of the present invention.

[0383] The clothing treatment device of the present invention may further include a heating wire (544, 545, 546) that heats the compressor (243) from the outside of the casing (400).

[0384] The coil (540) may further include the heating wire (544, 545, 546), and the heating wire (544, 545, 546) may be inserted into the casing (400) or extended to the outside of the casing (410) from the control panel (280), etc., unlike the first phase coil (541), the second phase coil (542), and the third phase coil (543) without being connected to the terminal (440).

[0385] The above heating wires (544, 545, 546) can be controlled to supply current for the set time. As a result, the heating wires (544, 545, 546) themselves can be heated, and current can also be supplied to the casing (410) so that the surface of the casing (410) can be heated.

[0386] While current is supplied to the heating wires (544, 545, 546), the current supply to the driving unit (500) disposed inside the casing (410) can be blocked. That is, while current is supplied to the heating wires (544, 545, 546) of the first phase coil (541), the second phase coil (542), and the third phase coil (543), the current supply can be blocked.

[0387] Thereby, the casing (410) is heated so that the compressor (243) can be heated to a set temperature for a set time.

[0388] Of course, while current is supplied to the heating wires (544, 545, 546), current may be supplied to at least one of the first phase coil (541), the second phase coil (542), and the third phase coil (543), but current may be controlled to be blocked from being supplied to all of the first phase coil (541), the second phase coil (542), and the third phase coil (543). As a result, the compressor (243) can be heated to the set temperature more quickly.

[0389] Meanwhile, when current is supplied to the entire first phase coil (541), second phase coil (542), and third phase coil (543), the supply of current to the heating wires (544, 545, and 546) can be blocked. Accordingly, when the driving unit (500) is driven, an additional magnetic field other than the stator (510) can be blocked from affecting the driving unit (500).

[0390] The above heating wires (544, 545, 546) may include a compression wire (546) wound in an area facing the compression section on the outer circumferential surface of the casing. Accordingly, the heating wire can directly heat the compression section (600) to prevent the refrigerant flowing into the compression section (600) from being cooled or the heating from being delayed.

[0391] The above heating wires (544, 545, 546) may include a central wire (545) wound on the outer circumferential surface of the casing in an area facing between the driving unit and the compression unit. As a result, the heating wire can prevent the refrigerant discharged from the compression unit (600) from being arbitrarily cooled while moving inside the casing (400).

[0392] The above heating wire may include a driving wire (544) wound in a region facing the driving unit on the outer surface of the casing. This prevents the refrigerant discharged from the compression unit (600) from being arbitrarily cooled while passing through the driving unit (500).

[0393] The heating wire (544, 545, 546) may include at least one of the compression wire (546), the drive wire (544), and the central wire (545). That is, the heating wire (544, 545, 546) may include only one of the compression wire (546), the drive wire (544), and the central wire (545), the heating wire (544, 545, 546) may include all of the compression wire (546), the drive wire (544), and the central wire (545), or the heating wire (544, 545, 546) may include but exclude one of the compression wire (546), the drive wire (544), and the central wire (545).

[0394] Figure 21 illustrates an embodiment of a control method of the garment treatment device of the present invention for heating a compressor through the aforementioned structure.

[0395] The above control method can be applied to both cases where the coil (540) includes the first phase coil (541), the second phase coil (542), and the third phase coil (543), and cases where the coil includes the heating wire (544, 545, 546).

[0396] The clothing treatment device of the present invention may include a preheating step (S1) of supplying current to the compressor (243) to heat the compressor (243) when the drying cycle starts, and a driving step (S3) of driving the compressor to compress the refrigerant.

[0397] The above driving step (S3) is a step in which the driving unit (500) receives current and the current is supplied to the first phase coil (541), the second phase coil (542), and the entire third phase coil (543) to form a rotating magnetic field. That is, the driving step (S3) is a step in which the rotor (520) and the driving shaft (530) rotate, and may correspond to a step in which the refrigerant is compressed in the compression unit (600) and the high-temperature gaseous refrigerant is discharged through the discharge pipe (410).

[0398] The above driving step (S3) is a step in which hot air is supplied to the inside of the drum (150), and a drying process including a heating step in which the RPM of the compressor (243) increases to a target RPM, a constant rate step in which the hot air is continuously supplied until the temperature inside the drum (150) increases to a specific temperature when the RPM of the compressor (243) increases to the target RPM, and a decreasing rate step in which the hot air is supplied until the drying of the clothes is completed when the temperature inside the drum (150) increases to a specific temperature or higher can be performed.

[0399] The above target RPM may correspond to the maximum RPM at which the RPM of the compressor reaches the highest level during the above drying cycle.

[0400] However, the above preheating step (S1) may correspond to a step in which the refrigerant is blocked from being compressed in the compression unit (600) and the entire inside of the casing (400) is heated by the supplied current.

[0401] The above preheating step (S1) may be a step in which current is supplied to at least one of the first phase coil (541), the second phase coil (542), and the third phase coil (543), but current is controlled to be blocked from being supplied to all of the first phase coil (541), the second phase coil (542), and the third phase coil (543).

[0402] Alternatively, the preheating step (S1) may be a step in which current is supplied to the heating wire.

[0403] As a result, the preheating step (S1) may correspond to a step in which only the temperature of the compressor (243) increases while current is supplied to the driving unit (500) or the coil (540), but a rotating magnetic field is not formed, so that the rotor (520) or the driving shaft (530) does not rotate, and compression of the refrigerant is not performed in the compression unit (600).

[0404] The heat exchange unit (240) may be equipped with a temperature sensor that detects the temperature at a portion connected to the refrigerant pipe or the casing (400). Accordingly, the garment treatment device of the present invention can perform the heating step until the set temperature is reached through the temperature sensor of the refrigerant or the temperature of the casing (400).

[0405] Accordingly, the clothing treatment device of the present invention may further include a detection step (S2) for detecting the temperature inside the casing (410) or calculating the temperature inside the casing (410) based on the temperature of a component connected to the outside of the casing (410) or a refrigerant.

[0406] The above preheating step (S1) is terminated when the temperature inside the casing (400) reaches the set temperature in the above detection step (S2), and the driving step (S3) can be performed.

[0407] Alternatively, the detection step (S2) may be a step of measuring a set time for which current is supplied to the coil (540) from the control panel (280).

[0408] The above preheating step (S1) is terminated when the set time has elapsed in the above detection step (S2), and the driving step (S3) can be performed.

[0409] Accordingly, the garment treatment device of the present invention can prevent the refrigerant from being delayed in heating or arbitrarily cooled in the driving step (S3), and can quickly complete the preheating step (S1) and quickly enter the constant rate step (S2). Therefore, the drying time for performing the drying process is shortened, energy efficiency is increased, and the durability of the compressor (243) is also guaranteed.

[0410] 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.
