For example, when a garment is washed with washing water, it may be referred to as a garment to be washed; when a wet garment is dried using heat, it may be referred to as a garment to be dried; and when a dry garment is refreshed using hot air, cold air, or steam, it may be referred to as a garment to be refreshed. Accordingly, washing, drying, or refreshing of the garment can be performed through the drum (3) of the garment processing device.
[0112] The cabinet (1) may include a cabinet opening provided at the front of the cabinet (1) through which an object enters and exits, and the cabinet (1) may be provided with a door (12) rotatably mounted on the cabinet to open and close the input opening.
[0113] The above door (12) may consist of an annular door frame (121) and a viewing window (122) provided in the center of the door frame.
[0114] Here, to help understand the detailed structure of the clothing processing device to be described below, the direction facing the door (12) relative to the center of the cabinet (1) can be defined as the front.
[0115] Additionally, the direction opposite to the direction facing the door (12) can be defined as Rear, and the Right and Left directions can be naturally defined in dependence on the front and rear directions defined above.
[0116] The tub (2) is provided in a cylindrical shape with a longitudinal axis parallel to or maintaining 0 to 30° with the bottom surface of the cabinet to form a space in which water can be stored, and has a tub opening (21) at the front to communicate with the inlet.
[0117] The tub (2) can be fixed to the lower surface (bottom surface) of the cabinet (1) by a lower support member (13) including a support bar (13a) and a damper (13b) connected to the support bar (13a), and accordingly, vibrations generated in the tub (2) by the rotation of the drum (3) can be dampened.
[0118] Additionally, an elastic support member (14) fixed to the upper surface of the cabinet (1) may be connected to the upper surface of the tub (2), and this may also serve to dampen vibrations generated in the tub (2) and transmitted to the cabinet (1).
[0119] The drum (3) is provided in a cylindrical shape with a longitudinal axis parallel to or maintaining an angle of 0 to 30° with respect to the bottom surface of the cabinet to accommodate an object, and a drum opening (31) communicating with the tub opening (21) may be provided at the front. The angle formed by the central axes of the tub (2) and the drum (3) with respect to the bottom surface may be the same.
[0120] Additionally, the drum (3) may include a plurality of through holes (33) provided to penetrate the outer surface. Air and washing water may enter and exit between the inside of the drum (3) and the inside of the tub (4) through the through holes (33).
[0121] A lifter (35) for stirring an object when the drum (3) rotates may be further provided on the inner surface of the drum (3), and the drum (3) may be rotated by a driving unit (6) provided at the rear of the tub (2).
[0122] The above drive unit (6) may be provided with a stator (61) fixed to the back surface of the tub (2), a rotor (63) that rotates by electromagnetic action with the stator, and a rotating shaft (65) that passes through the back surface of the tub (2) and connects the drum (3) and the rotor (63).
[0123] The stator (61) may be fixed to the rear surface of a bearing housing (66) provided on the back surface of the tub (2), and the rotor (63) may consist of a rotor magnet (632) provided on the radially outer side of the stator and a rotor housing (631) connecting the rotor magnet (632) and a rotation axis (65).
[0124] The bearing housing (66) may be equipped with a plurality of bearings (68) that support a rotating shaft (65) inside.

[0126] Meanwhile, a clothing processing device according to one embodiment of the present disclosure may further include a water supply hose (51) that receives water from the outside, and the water supply hose (51) forms a flow path that supplies water to the tub (2).
[0127] Additionally, a gasket (4) may be provided between the inlet of the cabinet (1) and the tub opening (21). The gasket (4) serves to prevent water inside the tub (2) from leaking into the cabinet (1) and to prevent vibrations of the tub (2) from being transmitted to the cabinet (1).
[0128] Meanwhile, a clothing processing device according to one embodiment of the present invention may further include a drainage unit (52) for discharging water inside the tub (2) to the outside of the cabinet (1).
[0129] The above drainage section (52) may include a drain pipe (522) that forms a drainage channel for water to move inside the tub (2) and a drainage pump (521) that drains through the drain pipe (522). The drainage pump (521) can generate a pressure difference inside the drain pipe (522) to discharge water inside the tub (2) to the outside.
[0130] More specifically, the drain pipe (522) may include a first drain pipe (522a) connecting the lower surface of the tub (2) and the drain pump (521), and a second drain pipe (522a) having one end connected to the drain pump (521) to form a path for water to move outside the cabinet (1).
[0131] A clothing processing device according to one embodiment of the present disclosure may further include an induction module (8) for heating the drum (3). The induction module (8) can induction heat the drum (3). Hereinafter, the induction module (8) may also be referred to as an induction heater (8).
[0132] The induction module (8) can be mounted on the circumferential surface of the tub (2). The induction module (8) can generate a magnetic field by applying current to a coil wound with a wire. The induction module (8) inductively heats the circumferential surface of the drum (3) through the magnetic field. When the induction module is operated, the outer surface of the drum facing the induction module (8) can be heated to a very high temperature in a very short time.
[0133] The above induction module (8) can be controlled by a module control unit (86) fixed to the cabinet (1) or tub (2). The module control unit (86) can control the temperature inside the tub by controlling the operation of the induction module (8). The module control unit (86) may include a processor that controls the operation of the clothing processing device. The module control unit (86) may include an inverter processor that controls the induction module (8). That is, the operation of the clothing processing device and the operation of the induction module (8) can be controlled through a single processor.
[0134] The processor controlling the induction module (8) and the processor controlling other components of the garment processing device may be provided separately. The processor controlling the induction module (8) and the processor controlling other components may be connected to each other via communication. Accordingly, the efficiency of control can be improved and the processor can be prevented from overloading.
[0135] A temperature sensor (95) may be provided inside the tub (2). The temperature sensor (95) may be connected to the control unit (9) to transmit internal temperature information of the tub (2) to the control unit (9). In particular, it may be provided to sense the temperature of washing water or humid air. Therefore, it can be referred to as a washing water temperature sensor.
[0136] The temperature sensor (95) may be provided near the bottom of the tub. Thus, the temperature sensor (95) may be located lower than the bottom of the drum. FIG. 2 illustrates a temperature sensor (95) provided so that it is in contact with the bottom surface of the tub. However, it may be provided at a certain distance from the bottom surface. Accordingly, the washing water or air surrounds the temperature sensor, allowing the temperature of the washing water or air to be measured accurately.
[0137] The temperature sensor (95) may be mounted by penetrating from the bottom to the top of the tub, but may also be mounted by penetrating from the front to the rear of the tub. That is, it may be mounted by penetrating the front surface (the surface forming the tub opening) rather than the circumferential surface of the tub.
[0138] Accordingly, when the garment processing device heats the washing water through the induction module (8), it can detect whether the washing water has been heated to a target temperature using a temperature sensor. Based on the detection result of this temperature sensor, the operation of the induction module can be controlled.
[0139] Additionally, when all the washing water has been drained, the temperature sensor (95) can detect the temperature of the air. Remaining washing water or cooling water may be present at the bottom of the tub. The temperature sensor (95) can sense the temperature of the humid air.
[0140] A clothing processing device according to one embodiment of the present disclosure may include a drying temperature sensor (96). The location of the drying temperature sensor (96) may be different from the location of the temperature sensor (95) described above. The temperature measurement target of the drying temperature sensor (96) may be different from the temperature measurement target of the temperature sensor (95) described above.
[0141] The above drying temperature sensor (96) can detect the temperature of the air heated through the induction module (8). That is, the drying temperature sensor (96) can detect the drying temperature. The drying temperature sensor (96) can detect whether the air has been heated to a target temperature. Based on the detection result of this drying temperature sensor, the operation of the induction module (8) can be controlled.
[0142] The above drying temperature sensor (96) may be located on the upper part of the tub (2). The drying temperature sensor (96) may be provided near the induction module (8). The drying temperature sensor (96) may be provided on the inner side of the tub (2) away from the projection plane of the induction module (8). The drying temperature sensor (96) may detect the temperature of the circumferential surface of the drum (3) facing the drying temperature sensor (96). The above-mentioned temperature sensor (95) is provided to detect the temperature of the surrounding water or air, and the drying temperature sensor (96) may be provided to detect the temperature of the drum or the temperature of the drying air around the drum.
[0143] Since the above drum (3) is a rotating configuration, the temperature of the air near the outer surface of the drum (30) can be detected indirectly to detect the temperature of the circumferential surface of the drum.
[0144] The above temperature sensor (95) can determine whether to continue operating the induction module until the target temperature or to vary the output of the induction module. The above drying temperature sensor (96) can determine whether the drum is overheated. If the module control unit (86) determines that the drum is overheated, it can forcibly stop the operation of the induction module.
[0145] A garment processing device according to one embodiment of the present disclosure may have a drying function. In this case, the garment processing device according to one embodiment of the present disclosure may be referred to as a dryer and washing machine.
[0146] The above clothing processing device can dry an object by cooling the air on the inner surface of the tub and discharging condensed moisture to the outside. Alternatively, it can dry an object by discharging humid air inside the tub to the outside and sucking in dry air.
[0147] In other words, drying can be performed through self-condensation of moisture even without air circulation. Cooling water can be supplied into the tub to perform moisture condensation more effectively and enhance drying efficiency. Drying efficiency can be improved as the surface area where the cooling water meets the tub—that is, the surface area where the cooling water contacts the air—is larger.
[0148] Cooling water can be supplied by spreading widely from the back, one side, or both sides of the tub. Through this supply of cooling water, the cooling water flows along the inner surface of the tub, preventing it from entering the drum.
[0149] At this time, there is no need to provide a separate heater for drying. That is, drying can be performed using an induction module (8). In other words, through a single induction module, heating of the washing water during washing, heating of the object during spin-drying, and heating of the object during drying can all be performed.
[0150] When the drum (3) is driven and the induction module (8) is driven, the entire circumferential surface of the drum can be heated. The heated drum exchanges heat with the wet laundry, thereby heating the laundry. Of course, the air inside the drum can also be heated. Therefore, when air is supplied into the interior of the drum (3), the air that has exchanged heat and evaporated moisture can be discharged to the outside of the drum (3).
[0151] The air supply location and the air discharge location can be determined so that heated air is evenly supplied to the object to be dried and humid air is smoothly discharged. Air can be supplied from the front upper part of the drum (3) and discharged through the rear lower part of the drum (3), that is, the rear lower part of the tub.
[0152] A detailed explanation of this will be provided later.
[0153] Therefore, since the air itself is not heated directly, the temperature of the heated air can be lower than that of a conventional heater dryer. Consequently, one can expect the effect of preventing damage or deformation of clothing caused by high temperatures.
[0154] Furthermore, as described above, the induction module is driven along with the driving of the drum, and the clothing repeatedly rises and falls as the drum is driven, and since the heating position of the drum is the upper part rather than the lower part of the drum, overheating of the clothing can be effectively prevented.
[0155] The above clothing processing device may be equipped with a control panel (92). The control panel (92) may be provided on the front or top surface of the clothing processing device. The control panel (92) may provide a user interface. Various inputs by the user may be performed through the control panel (92). Various information of the clothing processing device may be displayed on the control panel (92). That is, an operation section for operation by the user and a display section for displaying information to the user may be provided on the control panel (92).
[0157] FIG. 3 is an exploded view of the induction module of a clothing processing device according to the present embodiment.
[0158] Hereinafter, the induction module of the clothing processing device according to the present embodiment will be described in detail with reference to FIG. 3.
[0159] A clothing processing device according to one embodiment of the present disclosure may be equipped with an induction module (8) that induction heats a drum (3). The induction module (8) can heat the drum (3) to heat the washing water. The induction module (8) can heat the drum (3) to dry the laundry. The principle by which the induction module (8) heats the drum (3) is as follows.
[0160] The induction module (8) can be mounted on the outer surface of the tub (2). The induction module (8) can generate a magnetic field by applying current to a coil (81) on which a wire is wound. The induction module (8) can heat the circumferential surface of the drum (3) through the generated magnetic field. The wire may include a core wire and a coating that wraps around the core wire. The core wire may be a single core wire. Of course, multiple core wires may be intertwined to form a single core wire. The thickness or diameter of the wire may be determined by the thickness of the core wire and the coating.
[0161] When an alternating current with changing phase flows through the coil (81) wound with the above wire, the coil (81) forms a radial alternating magnetic field according to Ampere's circuit law.
[0162] The above alternating magnetic field is concentrated toward a drum (metal material) made of a conductor with high permeability. The above magnetic permeability refers to the degree to which a medium is magnetized in response to a given magnetic field. At this time, according to Faraday's law of induction, an eddy current is formed in the drum (3). The eddy current flows along the drum (3) made of a conductor and is converted into Joule heat by the resistance of the drum (3) itself, thereby directly heating the inner wall of the drum (3).
[0163] When the inner wall of the drum (3) is directly heated, the temperature of the air inside the drum (3) and the temperature of the laundry in contact with the inner wall of the drum (3) rise together. Therefore, since direct heating of the laundry is possible, faster drying is possible compared to a drying device that uses only an indirect heating method, such as a hot air drying method or a low-temperature dehumidification drying method.
[0164] In the case of a garment processing device with a washing function, the washing water can be heated without the need for separate heating wires and water passages. Since the washing water continuously comes into contact with the inner and outer walls of the drum (3) heated to a high temperature, it is not necessary to form separate water passages and heating wires in the lower part of the tub. According to the method described above, faster heating of the washing water is possible compared to the method of forming separate water passages and heating wires in the lower part of the tub and using them for heating.
[0165] The induction module (8) according to the present embodiment may include a coil (81), a base housing (82), and a module cover (83).
[0166] The induction module (8) is provided on the outer surface of the tub (2) and can heat the drum (3) through a magnetic field generated by applying current to the coil (81).
[0167] The base housing (82) may be provided on the outer surface of the tub (2) at a predetermined distance apart.
[0168] The base housing (82) can accommodate and support the wound coil (81). The base housing (82) may have a shape corresponding to the outer surface (or circumferential surface) of the tub (2). The base housing (82) and / or the induction module (8) may be spaced apart from the tub (2) at a constant distance.
[0169] Thus, the amount of magnetic field transmitted through the base housing (82) does not vary depending on the position, so the drum (3) can be heated uniformly.
[0170] The tub (2) may include a tub connection part (22). The tub connection part (22) can secure the induction module (8) to the circumferential surface of the tub (2). The base housing (82) and the tub (2) may be spaced apart by the length of the tub connection part (22).
[0171] The base housing (82) may include a housing connection part (821) provided at a position corresponding to the tub connection part (22). The tub connection part (22) and the housing connection part (821) are combined so that the induction module (8) can be fixed to the outer surface of the tub (2).
[0172] The coil (81) may be wound and provided in the base housing (82). The coil (81) may be wound along the upper surface of the base housing (82). The size of the wound coil (81) may be equal to or smaller than the length of the tub (2) in the longitudinal direction of the tub (2).
[0173] This prevents other parts within the clothing processing device from heating up.
[0174] However, if it is provided to be excessively shorter than the length of the tub (2), effective heat transfer may be difficult, so it may be wound so as to be positioned close to the front surface of the tub (2) and the rear surface of the tub (2).
[0175] The module cover (83) can cover the upper side of the coil (81). The module cover (83) can have a shape corresponding to the base housing (82). The module cover (83) can be combined with the base housing (82).
[0176] The module cover (83) may be provided with a cooling channel connection part (832) that communicates with the module cooling duct (755) described later. Although the drawing shows the cooling channel connection part (832) positioned at the center of the module cover (83), it is not limited thereto.
[0177] That is, depending on the structure in which air is discharged from the induction module (8), the cooling channel connection (832) can be formed at various locations.
[0179] Figure 4 is a drawing showing an induction module.
[0180] Referring to FIG. 4, the induction module (8) may further include a permanent magnet (84) and a permanent magnet housing (85) that accommodates the permanent magnet (84). A module cover (83) may be attached to the top of the permanent magnet housing (85).
[0181] The induction module (8) may include a base housing (82) that accommodates a coil (81), a permanent magnet housing (85) that accommodates a permanent magnet (84), and a module cover (83) that covers the permanent magnet housing (85) to prevent the permanent magnet (84) from being removed.
[0182] The above permanent magnet (84) can serve as a blocking member. The permanent magnet (84) can prevent other components in the surrounding area, other than the drum (3), from being heated. The permanent magnet (84) can increase heating efficiency by concentrating the magnetic field generated from the coil (81) toward the drum.
[0183] The base housing (82) may be provided in a roughly rectangular shape. The rectangular shape preferably means a rectangular or oblong shape. A coil (81) is accommodated in the upper part of the base housing (82).
[0184] A base connecting part (821) is provided at the corner portion of the base housing (82), and it is preferable that the base connecting part (821) protrudes outward from the corner portion. In addition, a ring (823) to which a hook (856) of a permanent magnet housing (85) is coupled is provided at the edge of the base housing (82). It is preferable that a total of four rings (823) are provided, with two on each side of the long side portion of the base housing (82).
[0185] Meanwhile, it is preferable that the permanent magnet housing (85) be provided with a shape corresponding to the shape of the base housing (82). Accordingly, the permanent magnet housing (85) may be provided with a rectangular or oblong shape.
[0186] The permanent magnet housing (85) is provided with a mounting portion (853) in which a permanent magnet (84) is installed. Additionally, since the permanent magnet housing (85) is preferably composed of a single part, it is preferable to provide a connecting portion (854) that connects multiple mounting portions (853). The connecting portion (854) can be opened vertically. The connecting portion (854) can discharge heat generated from the coil (81).
[0187] Multiple mounting portions (853) may be provided, and it is preferable that they be provided radially in the direction of the edge near the center of the base housing (82). Since the mounting portion (853) is the part where the permanent magnet (84) is seated, it is preferable that it be a shape corresponding to the permanent magnet (84), that is, a narrow rectangular shape.
[0188] More specifically, the mounting portion (853) may include a long side mounting portion (853a), a short side mounting portion (853b), and a corner mounting portion (853c). Two long side mounting portions (853a) may be provided on each side approximately near the center of the long side of the base housing (82). Two short side mounting portions (853b) may be provided on each side approximately near the center of the short side of the base housing (82). Four corner mounting portions (853c) may be provided from the center of the base housing (82) toward the corners.
[0189] The penetration portion (855) may be provided to open vertically the space between the mounting portion (853) and the adjacent mounting portion (853), for example, in a part where the mounting portion (853) is not provided. That is, it is preferable for the penetration portion (855) to be provided in a shape corresponding to the shape of the space between the mounting portion (853) and the adjacent mounting portion. In addition, since the penetration portion (855) can function to discharge heat generated from the coil (81), it is preferable for it to have as large an area as possible to maintain the strength of the permanent magnet housing (85).
[0190] If high-temperature heat is applied to the permanent magnet (84), the atoms move in a disordered manner and lose their magnetism, which may lead to a problem of weakened durability of the induction module (8).
[0191] Therefore, by cooling the heat generated in the induction module through the cooling channel structure of the duct described above, it is possible to prevent the durability of the induction module from being weakened.
[0192] Meanwhile, a mounting connection part (851) is provided at the corner portion of the permanent magnet housing (85), and it is preferable that the mounting connection part (851) protrudes outward from the corner portion.
[0193] A hook (856) extending downward is provided on the edge of the permanent magnet housing (85), and the hook (856) is inserted and coupled to a ring (823) of the base housing (82). Additionally, a groove (855a) is provided at a predetermined location inside the permanent magnet housing (85), and the groove (855a) is coupled to a coupling part (833) (or hook) of the module cover (83).
[0194] Meanwhile, it is preferable that the shape of the module cover (83) corresponds approximately to the shape of the permanent magnet housing (85). For example, it is preferable that the module cover (83) has a rectangular shape. A through-hole (835) is provided in the center of the module cover (83), and outside air may be introduced or heat generated from the coil may be discharged through the through-hole (835).
[0195] A cover connection part (831) is provided at the corner portion of the module cover (83), and it is preferable that the hole of the cover connection part (831) be an elongated hole. A hook (833) that engages with the groove (855a) of the permanent magnet housing (85) is provided at the bottom of the module cover (83).
[0196] That is, the induction module (8) can be provided in such a way that the base connection part (821) of the base housing (82), the mounting connection part (851) of the permanent magnet housing (85), and the cover connection part (831) of the module cover (83) are connected.

[0244] The partition (73) divides the first flow path (C1) and the second flow path (C2) inside the chamber (72).
[0245] The partition (73) can be extended along the length of the chamber (72).
[0246] The partition wall (73) may include a first length portion (731) extending in the longitudinal direction of the chamber (72), a first width portion (736) extending in the width direction of the chamber (72) from the first length portion (731), and a second length portion (732) extending in the longitudinal direction of the chamber (72) from the first width portion (736) and facing the first length portion (731).

[0258] To explain the air flow again, the humid air inside the tub (2) can be guided to the first duct (71) by the blower (75). The humid air guided to the first duct (71) by the rotation of the blower (75), specifically the first impeller (751), passes through the first blower housing (750a) and flows into the chamber (72) through the inlet (725) of the circulation path (C1). The air flowing into the chamber (72) can flow along the circulation path (C1) between the partitions (73). The air flowing along the circulation path (C1) can be introduced into the tub (2) through the outlet (726) of the circulation path (C1).

The cold air introduced into the chamber (72) can flow between the partitions (73) within the second duct (72). The air flowing between the partitions (73) is introduced into the blower (75) through the outlet (723) of the cooling channel (C2).
[0260] The circulation channel (C1) and the cooling channel (C2) are separated by a partition wall, and humid air flows downward along the circulation channel (C1), and cold air flows upward along the cooling channel (C2). The humid air and the cold air exchange heat with each other through the partition wall (73). As the humid air flows along the circulation channel (C1) and is cooled, condensate may be formed. The condensate may descend to the lower side of the chamber (72) by gravity.
[0261] Condensate can be discharged to the outside of the tub (2) or clothing processing device through the condensate discharge channel (722).
[0262] That is, condensate can be discharged through the aforementioned drain pipe (522). Condensate that has descended to the bottom of the second duct (72) can be discharged through the inside of the tub (2) to the drain pipe through a separate condensate discharge channel (722) or directly to the drain pipe.
[0263] For effective heat exchange, the bulkhead (73) may be provided to have a thinner thickness compared to the second duct (72). This is because as the thickness of the bulkhead (73) increases, the heat exchange efficiency may decrease.
[0265] FIG. 8 is a drawing showing the interior of the blower unit of the clothing processing device according to the present embodiment.
[0266] According to the present embodiment, the first impeller (751) and the second impeller (752) can be rotated by a single blower motor (753).
[0267] As shown in FIG. 8, the blower unit (75) may include a first impeller (751), a second impeller (752), a blower unit motor (753), and a blower unit rotation shaft (754).
[0268] The first impeller (751) and the second impeller (752) may be configured to be rotated by a single blower motor (753). The first impeller (751) and the second impeller (752) may be connected to a blower rotation shaft (754) connected to the blower motor (753).
[0269] The blower unit rotation shaft (754) can be rotated by the blower unit motor (753) and thereby provide driving force to the first impeller (751) and the second impeller (752).
[0270] As described above, air flows through the circulation path (C1) to the front side of the tub (2), the first duct (71), the blower unit (75), and the second duct (72), and air flows through the cooling path (C2) to the rear side of the tub (2), the second duct (72), the blower unit (75), and the induction module (8).
[0271] To reiterate, the above airflow path does not exclude the possibility of separate configurations between each component. Likewise, it is clarified that it does not exclude the possibility of air being branched and flowing into separate components.
[0272] In the circulation path (C1), air is guided from the front to the rear side along the longitudinal direction of the tub (2), and in the cooling path (C2), air is guided from the rear side to the front side along the longitudinal direction of the tub (2).
[0273] The air passing through the circulation path (C1) and the cooling path (C2) is guided by a blower unit (75). However, the blower unit (75) can blow air within the circulation path (C1) and the cooling path (C2) through a single blower unit motor (753). Therefore, the direction of air flow in the circulation path (C1) and the cooling path (C2) may be different.
[0274] The first impeller (751) and the second impeller (752) are rotated by a single blower motor (753). The shapes of the first impeller (751) and the second impeller (752) may differ from each other to create different air flow paths.
[0275] However, the shapes of the first impeller (751) and the second impeller (752) do not always have to be different from each other. That is, even if the first impeller (751) and the second impeller (752) are formed identically, if a separate configuration is provided so that the blower motor (753) can rotate in a direction different from the direction in which it provides driving force, air can be smoothly guided in both the circulation path (C1) and the cooling path (C2).
[0277] FIG. 9 is a side view and a plan view of a blower unit of a clothing processing device according to the present embodiment. FIG. 9(a) is a side view of the blower unit and FIG. 9(b) is a plan view of the blower unit.
[0278] The structure of the blower section will be explained with reference to Figs. 9(a) and 9(b).
[0279] According to the present embodiment, the first duct (71) may be provided to be in communication with the first blower housing (750a). The second duct (72) may be in communication with the first blower housing (750a) forming a circulation path (C1) and the second blower housing (750b) forming a cooling path (C2).
[0280] Specifically, the third blower housing (750c) that accommodates the blower motor (753) is in communication with the second blower housing (750b), and as a result, the air guided to the third blower housing (750c) can be guided to the second blower housing (750b).
[0281] The second duct (72) can be connected to the first blower housing (750a) and the third blower housing (750c) at different locations.
[0282] For example, as illustrated in the drawing, the part where the second duct (72) is connected to the first blower housing (750a) may be located at a relatively lower part than the part where the second duct (72) is connected to the third blower housing (750c).
[0283] As described above, the first impeller (751) and the second impeller (752) may be configured to rotate around the same axis.
[0284] Thus, the first impeller (751) and the second impeller (752) can be rotated by a single blower motor (753).
[0285] In order to rotate the first impeller (751) and the second impeller (752) based on a single rotation axis, the first impeller (751) and the second impeller (752) may be positioned at different heights based on the height direction of the cabinet (1).
[0286] Of course, if the blower unit (75) is configured to be perpendicular to the height direction of the cabinet (1) as shown in the drawing, the first impeller (751) and the second impeller (752) may be located at the same height, but the length of the first duct (71) and the second duct (72) may be increased, resulting in a large amount of dead space within the cabinet (1). However, it goes without saying that it can be sufficiently modified if the size of the cabinet (1) is secured as needed. Below, for a clear understanding of the invention, the description is based on what is shown in the drawing. It is clarified that this does not exclude embodiments that modify matters that can be easily modified by a person skilled in the art.
[0287] That is, the first impeller (751) and the second impeller (752) may be provided to rotate coaxially at different heights. Accordingly, the first duct (71), the first blower housing (750a), the second blower housing (750b), and the third blower housing (750c) may have a structure in which they are stacked sequentially from the bottom with respect to the height direction of the cabinet.
[0288] The second blower housing (750b) may be provided to blow air to a module cooling duct (755) that cools the induction module (8). Additionally, the second blower housing (750b) may be provided to blow air toward a module control unit (86) that controls the operation of the induction module (8).
[0289] The module control unit (86) may be located adjacent to the induction module (8), but may be provided spaced apart as long as it can be electrically connected to the induction module (8).
[0290] Accordingly, the second blower housing (750b) may be configured to communicate with the module control unit (86) at a different location from the part communicating with the module cooling duct (755).
[0291] Thus, the air flowing into the second blower housing (750b) through the second duct (72) can be branched and blown to the induction module (8) and the module control unit (86), respectively.
[0293] Certain embodiments or other embodiments of the disclosure described above are not mutually exclusive or distinct from each other. Any or all elements of the embodiments of the disclosure described above may be combined with another or combined with each other in configuration or function.
