Description

Technology Field

[0001] The present invention relates to a clothing processing device and a control method thereof.

[0002] delete Background Technology

[0003] A garment processing device is a device that processes one or more of a washing process for removing foreign substances from garments or a drying process for removing moisture from garments. Such a garment processing device was able to perform the washing or drying process by receiving a large quantity of garments in a rotating drum and applying physical force or centrifugal force to the garments.

[0004] However, since the garment processing device was designed to handle a large volume of clothing, there was a problem with low energy efficiency when processing small quantities of clothing. Consequently, even if users had clothes that needed washing or drying, it was common practice to collect the clothes until they reached a large volume before performing the washing or drying process with the garment processing device. However, during the process of leaving the clothes until they reached a large volume, there were problems such as the clothes becoming unnecessarily more contaminated or decaying.

[0005] Recently, to address this, an auxiliary device capable of processing a small amount of clothing has emerged, which is additionally installed in a clothing processing device (hereinafter referred to as the main device) capable of processing a large amount of clothing.

[0006] The auxiliary device was equipped with a smaller volume than the main device, allowing for the washing or drying of small quantities of clothing to be performed with less water, detergent, or energy. Accordingly, the user could use the auxiliary device when a small amount of clothing needs to be processed and the main device when a large amount of clothing needs to be processed, thereby processing the clothing with optimal efficiency.

[0007] Since such auxiliary devices are provided independently of the main device, they are configured to be controlled independently of the main device. Accordingly, it was common for the auxiliary device to be equipped with a control panel, independently of the main device, that has a plurality of input sections for receiving commands to perform washing or drying operations.

[0008] However, since the auxiliary device is equipped with a smaller height and volume than the main device, it was difficult to secure the area for installing the control panel on the auxiliary device, and there was a problem in that it was difficult for the user to operate the control panel installed in a narrow area.

[0009] In addition, when the main device is provided as a front-load type device having an opening at the front and the auxiliary device is provided as a drawer type positioned at the bottom of the main device and pulled out forward, there was the inconvenience of the user having to bend their body to operate the auxiliary device.

[0010] Furthermore, although the main unit's control panel or control unit had the capability to operate the auxiliary unit as well, there was structural waste in having to additionally place control panels and other components on the auxiliary unit.

[0011] Furthermore, since the main device and the auxiliary device were not controllably connected to each other, it was difficult for the user to control the main device and the auxiliary device as a whole, and there was the inconvenience of having to check the status of the main device or the auxiliary device on each respective device. The problem to be solved

[0013] The present invention aims to solve the problem of providing a clothing processing device capable of controlling the auxiliary device through the main device.

[0014] The present invention aims to solve the problem of providing a clothing processing device in which a main device and an auxiliary device can be paired with each other.

[0015] The present invention aims to solve the problem of providing a clothing processing device configured such that the pairing command can be input into a multi-functional input unit in the auxiliary device.

[0016] The present invention aims to solve the problem of providing a clothing processing device capable of displaying the status of the auxiliary device from the main device when the pairing of the auxiliary device and the main device is completed. means of solving the problem

[0018] To solve the above-mentioned problem, the present invention provides an auxiliary device comprising: an auxiliary cabinet disposed at the bottom of a cabinet and having an auxiliary opening at the front; a drawer received in the auxiliary cabinet and configured to be able to be pulled in and out through the auxiliary opening; an auxiliary drum received in the drawer and having an input opening disposed at the top for receiving clothing; an auxiliary module provided inside the auxiliary cabinet and configured to communicate with a communication module; an auxiliary control unit for controlling the auxiliary module; a pull-out unit provided in the auxiliary cabinet for pulling out the drawer; and a multi-functional input unit provided on the exposed surface of the drawer for receiving a pull-out command for the pull-out unit to pull out the drawer.

[0019] The above multi-functional input unit may also be configured to receive a pairing command in which the auxiliary module recognizes and communicates with the communication module.

[0020] The above multi-functional input unit can be configured to receive the connection command when input is continuously received for a certain period of time.

[0021] The apparatus further includes a control panel coupled to the cabinet and receiving commands to control the control unit and the communication module, and the control panel may include a device connection unit that receives a pairing command for the communication module to recognize and communicate with the auxiliary module.

[0022] The communication module is configured to transmit recognition information to the auxiliary module when the connection command is input to the device connection unit, and the auxiliary module can transmit recognition information to the communication module when the connection command is input to the multi-functional input unit.

[0023] When the communication module receives the recognition information, it maintains a communication state with the auxiliary module, and when the auxiliary module receives the recognition information, it can maintain a communication state with the communication module.

[0024] The control panel may further include a display unit on the outside that indicates the state in which the communication module and the auxiliary module recognize each other.

[0025] The control unit may approve the pairing when it confirms that the communication module and the auxiliary module have received recognition information from each other, or may indicate on the display unit whether to approve the pairing.

[0026] The above display unit can display the connection completion status externally when the communication module and the auxiliary module are connected.

[0027] The above display unit can display the status of the auxiliary module or the auxiliary control unit if the connection between the communication module and the auxiliary module is approved.

[0028] The above display unit can display the status of the integrated control unit or the auxiliary control unit to which power is supplied when power is supplied to only one of the integrated control unit or the auxiliary control unit while the connection between the communication module and the auxiliary module is approved.

[0029] When power is supplied to both the control unit and the auxiliary control unit while the connection between the communication module and the auxiliary module is approved, the display unit can display the status of the control unit and the auxiliary control unit separately, starting from the state where power is supplied to both.

[0030] If the communication module and the auxiliary module have previously been paired, they can be configured to automatically pair after power is supplied.

[0031] If the communication module is connected to the auxiliary module, it stores the recognition information of the auxiliary module, and if the auxiliary module is connected to the communication module, it can store the recognition information of the communication module.

[0032] Even if the above auxiliary module has previously completed a connection with the above communication module, it can disconnect the connection (pairing) with the above communication module when the above multifunction input unit receives the connection command again.

[0033] Even if the above auxiliary module has previously completed a connection with the above communication module, if the above multifunction input unit receives the connection command again, the recognition information of the above communication module can be deleted. Effects of the invention

[0035] The present invention has the effect of being able to control even small auxiliary devices at once using a large main device.

[0036] The present invention has the effect of allowing a user to check the status of both devices by checking only one device.

[0037] The present invention has the effect of enhancing a sense of unity and aesthetic appeal by having a control panel placed on the main device while minimizing the input section for receiving commands on the auxiliary device.

[0038] The present invention has the effect of allowing the screen displaying the status of the auxiliary device to be omitted. Brief explanation of the drawing

[0042] FIG. 1 illustrates the exterior of the clothing processing device of the present invention.

[0043] The clothing processing device of the present invention may be equipped with either a washing machine (1) or a dryer (2), or may include one or more of a main device (4) in which the washing machine (1) and the dryer (2) are integrated, and an auxiliary device (5) disposed below the main device (4).

[0044] In the following description, the clothing processing device of the present invention is described based on the assumption that it is equipped with a main device (4) and an auxiliary device (5) positioned below the main device (4). However, this is for illustrative purposes only and does not exclude the form in which the clothing processing device of the present invention is configured with a washing machine (1), a dryer (2), or a washing machine (1) and a dryer (2) arranged vertically.

[0045] The main device (4) of the present invention may include a cabinet (10) forming an exterior. An opening (14) through which clothing can be inserted or removed may be provided at the front of the cabinet (10), and the opening (14) may be opened or closed by a door (200).

[0046] The door (200) may be rotatably coupled to the cabinet (10) to selectively open and close the opening (14). When the door (200) is fixed or locked to the cabinet (10), it may be provided so that only the front surface, which is made of a transparent material, is exposed. To this end, the front surface of the door (200) may be made of glass or a transparent material such as plastic or acrylic.

[0047] A control panel (100) that receives commands to control the clothing processing device of the present invention or displays information externally may be disposed on the upper part of the door (200).

[0048] The cabinet (10) may include a front panel (11) forming a front surface, and the control panel (100) may be installed on the front panel (11).

[0049] The control panel (100) may be equipped with an input section to receive various commands from a user. The control panel (100) may also be equipped with a display section (150) that displays information of the clothing processing device on the outside. At least a portion of the control panel (100) may be equipped as a touch panel to perform the functions of both the input section and the display section (150).

[0050] The control panel (100) may be provided with a width greater than its height, and may be provided in a shape such as an elliptical shape or a track. Accordingly, the control panel (100) can display more information or easily display completed sentences, phrases, etc., than when provided in a circular shape.

[0051] The control panel (100) may be configured to receive a command to perform the course, display the status of performing the course, information necessary to perform the course, etc.

[0052] The above control panel (100) may include one or more of a plurality of buttons or touch panels that receive commands from a user, a microphone that receives the user's voice, a camera or proximity sensor that receives the user's actions or status, a screen that displays visual information to the user, and a speaker that conveys auditory information to the user.

[0053] When the opening (14) of the clothing processing device of the present invention is provided in a front-load type at the front of the cabinet, the control panel (100) may be positioned above the door (11) at the front of the cabinet (10). This ensures accessibility and identifiability.

[0054] Of course, if the clothing processing device of the present invention is provided as a top-load type in which the opening (14) is provided on the upper part of the cabinet (10), the control panel (100) may be positioned in front of the door (200) on the upper surface of the cabinet (10).

[0055] In the case where an auxiliary device (5) is positioned at the bottom of the main device (4), the control panel (100) may be provided as a composite panel capable of controlling one or more of the main device (4) and the lower auxiliary device (5) at once.

[0056] The above main device (4) may further include a main communication module (1400) configured to communicate with the outside.

[0057] The main communication module (1400) may be configured in any way as long as it can communicate with at least one of an auxiliary device (5) provided separately from the main device (4), an external terminal, a router, and a server.

[0058] For example, the main communication module (1400) may be equipped with a wireless communication module such as Wi-Fi, Bluetooth, NFC, etc.

[0059] The main communication module (1400) may be connected to the control panel (100) and configured to transmit a signal input from the control panel (100) to an auxiliary device (5), an external terminal, a router, and a server. Additionally, the main communication module (1400) may be configured to transmit a signal received from the auxiliary device (5), an external terminal, a router, and a server to the control panel (100).

[0060] When the main device (4) of the present invention performs the configuration of a dryer (2), a filter (99) for filtering drum air from the outside of the drum may be placed on the upper part of the cabinet (10).

[0061] The filter (99) is provided to filter foreign substances in the circulation channel (91) that is housed inside the cabinet (10) and circulates air, and the circulation channel (91) may be positioned closer to the upper part of the cabinet (10) than to the lower part of the cabinet (10) so that the filter (99) can be pulled out upward from the upper panel (13) of the cabinet (10). The structure of the circulation channel (91) will be described later.

[0062] The door (200) may be coupled to the cabinet (10) in the form of a push button. When the door (200) is pressed toward the cabinet (10), the door (200) may be configured to sequentially repeat opening and closing the opening (14).

[0063] If the door (200) is provided in the form of a push button, even in a situation where the user cannot pull the door (200), such as when the user is holding laundry in both hands, the door (200) can be sequentially fixed to the cabinet (10) or separated from the cabinet (10) when pressed toward the opening (14).

[0064] The door (200) is rotatably coupled to a hinge positioned on one side of the opening (14). Accordingly, it is preferable that the locking part to which the door (200) is coupled or fixed to the cabinet (10) be installed in the area facing the hinge with respect to the opening (14).

[0065] The above door (200) may have a pressure part (250) disposed on the outer surface to induce a user to apply pressure to a place corresponding to the locking part. The pressure part (250) may be marked on the surface to be distinct from other areas, or may be visually distinguished by being provided with a separate light, etc.

[0066] The above door (200) may further include a sensing unit (240) configured to detect when a user presses or touches it, thereby separating the door (200) from the cabinet (10).

[0067] The sensing unit (240) may be configured to detect physical contact of a user. For example, the sensing unit (240) may be configured in any way that can detect physical contact of a user, such as a touch film, touch panel, physical button, or piezoelectric element installed on the door (200).

[0068] The door (200) can be opened from the cabinet (10) without pressing toward the cabinet (10) when the user touches or presses the sensing unit (240). This prevents damage or scratches from occurring when the door (200) is pressed by a user or an object.

[0069] The sensing unit (240) may be provided near the pressurizing unit (250). Thus, the user can intuitively recognize that the sensing unit (240) and the pressurizing unit (250) are areas that receive user input.

[0070] The sensing unit (240) may be provided by being embedded in the door (200) and may be provided to be displayed on the outer surface of the door (200). Accordingly, the sensing unit (240) may further include a separate light source. Of course, the area where the sensing unit (240) is installed on the surface of the door (200) may be marked, shaded, etc.

[0071] The clothing processing device of the present invention may additionally include an auxiliary device (5) disposed below the main device (4). The auxiliary device (5) may be disposed below the main device (4), and the main device (4) may be seated and disposed above the auxiliary device (5).

[0072] The auxiliary device (5) may include an auxiliary cabinet (10b) positioned at the bottom of the cabinet (10) of the main device (4), and a drawer (80) that is pulled out forward from the auxiliary cabinet (10b).

[0073] An auxiliary input unit (84) may be provided in front of the drawer (80) to receive a withdrawal command from the user to have the drawer (80) withdrawn forward.

[0074] The above auxiliary input unit (84) may be configured to receive additional commands in addition to the withdrawal command. Accordingly, the above auxiliary input unit (84) may be configured as a multi-functional input unit (84).

[0075] The above-mentioned multi-functional input unit (84) may be provided in any configuration as long as it can receive a withdrawal command by contacting the user's body. For example, it may be provided as a touch panel or a button.

[0076] The height at which the main device (4) is positioned can be increased due to the auxiliary device (5). Accordingly, when the main device (4) is provided as a front-load type in which the door (200) is positioned in front of the cabinet (10), the position of the opening (14) is also increased so that the user can easily access the door (200) without bending their waist less or not at all.

[0077] The detailed configuration of the main device and the auxiliary device above will be described later.

[0078] Of course, the auxiliary device (5) of the present invention may be mounted on the upper part of the cabinet (10). In this case, the auxiliary device (5) may include an auxiliary cabinet (10b), but the drawer (80) may be omitted.

[0079] Alternatively, the auxiliary device (5) may be placed in the upper part of the interior of the cabinet (10) and may share the cabinet with the main device (4).

[0080] In this case, the multi-functional input unit (84) may be positioned at the upper front of the auxiliary device (5) or at the front of the auxiliary device (10).

[0081] The following description is based on the assumption that the auxiliary device (5) is positioned at the bottom of the cabinet (10) and includes a drawer (80). However, the assumption that the auxiliary device (5) is positioned at the top of the cabinet (10) is not excluded.

[0082] FIG. 2 illustrates an internal cross-section when the clothing processing device of the present invention is equipped as a main device.

[0083] The clothing processing device of the present invention may include a tub (20) that stores water and is housed inside the cabinet (10), and a drum (30) that stores clothing and is rotatably housed in the tub (20).

[0085] The above tub body (21) may be provided with a plastic material or the like, and the inlet (22) may be provided protruding in a cylindrical shape smaller than the diameter of the tub body (21) from the front of the tub body (21).

[0086] The above input port (22) may be provided to communicate with the opening (14) of the cabinet (10).

[0087] Meanwhile, the tub (20) may further include a gasket (23) that seals the space between the inlet (22) and the opening (14).

[0088] The gasket (23) may be provided as a separate component from the tub body (21). It may be provided in a ring shape to seal the space between the inlet (22) and the opening (14).

[0089] The above gasket (23) may be made of an elastic material. Accordingly, the gasket (23) can maintain a state of sealing the opening (14) and the inlet (22) even when vibration occurs in the tub (20), and can prevent vibration from being transmitted to the opening (14) or the door (200).

[0090] The drum (30) may include a drum body (31) that is rotatably provided on the tub body (21) for storing clothing, and an inlet (35) that is positioned in front of the drum body (31) and communicates with the inlet (22) and the opening (14).

[0091] The drum body (31) may be provided in a cylindrical shape, and a through hole (33) communicating with the inside of the tub body (21) may be provided on the back or outer surface. The drum body (31) may be made of a metal material.

[0092] The clothing processing device of the present invention may include a water supply unit (50) that supplies water to the tub (20) and a drainage unit (60) that drains water from the tub (20).

[0093] The above water supply unit (50) may include a water supply valve (51) that is coupled to the cabinet (10) and connected to an external water source to selectively supply water, and a water supply pipe (52) that extends from the water supply valve (51) and delivers water supplied from the external water source. The water supply pipe (52) may be coupled to the tub body (21) or may be coupled to the end of the gasket (23).

[0094] If the above water supply pipe (52) can supply water to the above tub (20), the above water supply pipe (52) may be connected to any part of the tub (20).

[0095] The above drainage section (60) may include a discharge pipe (61) connected to the lower part of the tub (20) to discharge water from the tub (20), a drainage pump (62) that provides power to discharge water supplied from the discharge pipe (61) to the outside of the cabinet (10), and a drainage pipe (63) that extends from the drainage pump (62) to the outside of the cabinet (10) to discharge water.

[0096] The clothing processing device of the present invention may further include a water level sensor (24) for detecting the water level of the tub (20). The water level sensor (24) may be provided in any configuration as long as it can detect the water level inside the tub (20). For example, the water level sensor (24) may include a connecting pipe connected to the tub (20) and having a closed end, and a device part disposed at the top of the connecting pipe to detect pressure changes inside the connecting pipe.

[0097] The clothing processing device of the present invention may further include a support member (70) that supports the tub (20) inside the cabinet (10).

[0098] The support member (70) may include one or more of a suspension that supports the lower part of the tub (20) and a spring that supports the upper part of the tub (20).

[0099] The clothing processing device of the present invention may include a driving unit (40) having the same structure as a general washing machine (1).

[0100] In addition, the clothing processing device of the present invention may further include a heat supply unit (90) capable of circulating air inside the tub (20) or the drum (30) and heating the air.

[0101] The heat supply unit (90) may be positioned below the tub (20).

[0102] However, since the above tub (20) is configured closest to the drum (30) and the lower part of the above tub (20) is equipped with a drainage section (60), the above heat supply section (90) cannot be placed and positioned on the lower part of the above tub (20).

[0103] The heat supply unit (90) can be positioned on the upper part of the tub (20). That is, the heat supply unit (90) can be positioned above the opening (14) of the tub (20).

[0104] The heat supply unit (90) may include one or more of the following: a circulation channel (91) that extends from the tub (20) in at least one of the forward / backward and left / right directions to circulate air inside the tub (20); an evaporator (92) that is housed in the circulation channel (91) to cool the air and condense moisture; a condenser (93) that is positioned downstream of the evaporator (92) to heat the air; a compressor (94) that is positioned outside the circulation channel (91) to supply a refrigerant to the condenser (93) to heat the air; an expansion valve that expands and cools the refrigerant discharged from the condenser (93) and delivers it to the evaporator (92); and a circulation fan (96) that is positioned inside the circulation channel (91) to provide power to circulate the air.

[0105] The above circulation channel (91) may be configured such that one end is connected to the upper rear of the tub body (21) and the other end is connected to the upper front of the tub body (21) or to the gasket (24).

[0106] The above circulation fan (96) can be driven so that air is sucked into the circulation path (91) from the rear of the drum (30) and the air is discharged into the drum body (31) through the inlet (35).

[0107] Thus, the hot air generated in the heat supply unit (90) can be introduced into the inlet (35) and supplied evenly to the drum body (31), allowing the clothes to be dried evenly. Additionally, the air that has dried the clothes can pass through the through hole (33) by the negative pressure provided by the blower fan (96) and flow into one end of the circulation path (91) without difficulty.

[0108] As a result, the heat supply unit (90) can be configured to supply hot air into the drum body (31) even if the drum (30) is housed in the tub (20) and a plurality of through holes (33) are provided on the outer surface of the drum (30) and the air resistance is high.

[0109] Since the tub (20) is positioned at the bottom of the heat supply unit (90), the collection unit for collecting condensate and the water storage tank can be omitted. That is, water condensed inside the circulation channel (91) can be collected in the tub (20) and discharged to the drainage unit (60).

[0110] The clothing processing device of the present invention can perform a plurality of courses for processing clothing based on the above configuration. The courses may include a washing course for removing foreign substances from the clothing and a drying course for removing moisture from the clothing.

The integrated control unit may be embedded in the control panel (100) or may be provided as a control panel separately arranged from the control panel (100) and mounted inside the cabinet (10).

[0112] The above integrated control unit may be provided separately from the main communication module (1400) and may be provided to receive power directly from an external power source.

[0113] However, the main communication module (1400) can receive power directly from the external power source if the integrated control unit is connected to the external power source, regardless of whether the integrated control unit receives power.

[0114] The main communication module (1400) may be configured to receive standby power and may be configured to supply the standby power to the control panel (100). The control panel (100) may receive power separately and operate regardless of whether the integrated control unit receives power.

[0115] The clothing processing device of the present invention may include a driving unit (40) coupled to the tub (20) to rotate the drum (30).

[0116] The above drive unit (40) may include a stator (41) coupled to the rear of the tub body (21), a rotor (42) that rotates by the stator (41), and a rotation shaft (43) connecting the rotor (42) and the drum (30).

[0117] The above tub body (21) has the rotation shaft (43) passing through its rear surface, and a bearing housing that rotatably supports the rotation shaft (43) may be installed.

[0118] FIG. 3 illustrates in detail the internal structure of the cabinet of the clothing processing device of the present invention.

[0119] The above circulation channel (91) may be arranged to extend in an L-shape from the top of the tub (20) to secure the space for air movement or the area of ​​the evaporator (92) and condenser (93).

[0120] That is, after being extended forward from one side of the upper rear of the tub body (21), it can be extended to the other side of the upper front of the tub body (21).

[0121] The above circulation path (91) may include an inlet section (91a) extending from the rear to the front of the tub body (21), a moving section (91b) extending from the inlet section (91a) to the other front side of the tub body (21) or to the gasket (24), and an outlet section (91c) extending downward from the moving section (91b) and communicating with the inside of the gasket (24).

[0122] The above circulation channel (91) can be extended in the left-right direction from the top of the tub (20), and a filter (99), an evaporator (92), and a condenser (93) can be arranged sequentially inside.

[0123] The above circulation fan (96) may be provided to communicate with the above circulation channel (91).

[0124] The above circulation fan (96) may be installed inside the circulation channel (91) and may include a housing connecting the moving part (91b) and the discharge part (91c).

[0125] The above circulation fan (96) is positioned at the front of the tub body (21) to evenly distribute the weight at the rear of the tub body (21) to which the drive unit (40) is attached.

[0126] The above circulation fan (96) can be driven to move air from the inlet (91a) to the outlet (91c).

[0127] The water supply pipe (51) of the water supply unit (50) may be connected to a gasket (24). A nozzle unit (500) coupled to the end of the water supply unit (51) may be installed in the gasket (24). The nozzle unit (500) may be provided to evenly spray water supplied from the water supply pipe (51) into the drum body (31).

[0128] The clothing processing device of the present invention may further include a circulation unit (65) that recirculates and supplies water from the tub (20).

[0129] The above circulation unit (65) may include a circulation pump that is in communication with or placed on one side of the drainage pump (62), and a circulation hose that supplies water drained from the tub body (21) back to the tub (20).

[0130] Thus, water can be saved by reusing the water in the tub (20) during the washing or rinsing process, and the washing efficiency can be increased by evenly dissolving detergent and the like through the circulation unit (65).

[0131] The clothing processing device of the present invention may further include a detergent box (700) for storing detergent supplied to the tub (20).

[0132] The detergent box (700) can be positioned below the tub (20). The detergent box (700) can also be prevented from being interfered with by the heat supply unit (90) positioned above, and can be exposed to the user without difficulty even if the main device (4) is raised by the auxiliary device (5).

[0133] The detergent box (700) may be equipped with a detergent body that contains detergent and a detergent pump that sprays the detergent contained in the detergent body into a tub (20). Accordingly, it is possible to prevent water from the tub (20) from intruding into the detergent box (700) or detergent from being supplied arbitrarily.

[0134] The above detergent box (700) may be configured to supply detergent to at least one of the drainage section (60) or the circulation section (65).

[0135] When supplying detergent to the above circulation unit (65), the detergent can be supplied to the tub (20) while driving a circulation pump, etc., and during the circulation process, the detergent can be dissolved more easily in water and the detergent can be supplied evenly to the clothing.

[0136] A filtration filter (800) may be placed between the drainage pump (62) and the circulation unit (65) to prevent foreign substances discharged from the tub (20) from flowing back into the circulation unit (65).

[0137] The above filter (800) may be exposed to the front on one side of the detergent box (700) and may be provided to be detachably attached to the front.

[0138] The cabinet may further include a base (15) that supports the filter (800) and the detergent box (700).

[0139] The above base (15) can form the lower surface of the cabinet (10).

[0140] The base (15) may be provided to support the support member (70) and may support the detergent box (700) and the filter (800) without interfering with the support member (70).

[0141] The detergent box (700) may be detachably mounted on the base (15) and may be configured to be pulled in and out from the base (15). Thus, the user can continuously replenish the detergent in the detergent box (700) and wash it.

[0142] The front of the base (15) may further include a step panel (16) positioned at the bottom of the front panel (11) to guide the entry and exit of one or more of the detergent box (700) and the filter (800).

[0143] The above step panel (16) may have a hole through which the detergent box (700) and the filter (800) are inserted and removed, and may block the base (15) from being exposed to the outside.

[0144] The step panel (16) may be provided separately from the front panel (11). Thus, the front panel (11) and the step panel (16) may be provided with different materials. As a result, even if the front panel (11) is provided with a metal material that has high rigidity or is difficult to mold, the step panel (16) may be provided with a material that is easy to mold so as to guide or expose the insertion and removal of one or more of the detergent box (700) and the filtration filter (800).

[0145] FIG. 4 illustrates an example of the structure of the control panel of the clothing processing device of the present invention.

[0146] The above control panel (100) can be switched to either a washing mode that receives a command to perform a washing course or displays the status of a washing course, or a drying mode that receives a command to perform a drying course or displays the status of a drying course.

[0147] In addition, if there is an auxiliary device described below, it may be switched to an auxiliary mode that receives a command to execute the auxiliary device or displays the status of the auxiliary device.

[0148] The above control panel (100) must implement a washing mode for performing a washing course, a drying mode for performing a drying course, and an auxiliary mode for performing an auxiliary device.

[0149] Accordingly, it is preferable that the control panel (100) is equipped entirely as a touch panel with physical buttons and the like omitted, so that a washing mode, a drying mode, and an auxiliary mode are selectively displayed. This allows for the omission of multiple buttons and displays for performing the washing mode, drying mode, and auxiliary mode separately.

[0150] The above control panel (100) may be provided with a display part (150) in the central rectangular portion.

[0151] The above display unit (150) can display device information (I) indicating the current status of a product.

[0152] The above device information (I) may include composite information (I1) capable of controlling the main device (4). For example, the composite information (I1) may include one or more of phrases such as “washing and drying” or “main device,” icons, and pictograms.

[0153] The above device information (I) may include auxiliary information (I2) capable of controlling the auxiliary device (5). For example, the above auxiliary information (I2) may include one or more of phrases, icons, pictograms, such as “miniwash” or “auxiliary device”.

[0154] On one side of the above display unit (150), a power unit (110) that receives a power command to supply power to the control panel (100) and an execution unit (120) that receives an execution command to perform a selected course may be arranged.

[0155] When the above power supply unit (110) is input, the control panel (100) is activated through standby power and consumes power, but the above integrated control unit may not consume power.

[0156] When the above execution unit (120) is input, the integrated control unit can be controlled to receive power and perform a course capable of processing clothing.

[0157] The above power supply unit (110) and execution unit (120) may be provided with a touch area capable of touch input, so that it lights up when touch input is possible and turns off when touch input is not possible.

[0158] The above display unit (150) may be configured to display weight information related to the weight of the detected clothing, and status information regarding the selected course and option.

[0159] Furthermore, the above display unit (150) is equipped with a touch panel and can also perform the role of a course input unit (130) that receives a course selection command for selecting one of the courses provided by the clothing processing device, and an option selection unit (140) that receives an option selection command for adding additional conditions and functions to the course.

[0160] For example, a course selection section (130) for selecting a course may be displayed on the display section (150). For example, a selected course (C1) may be displayed large, and courses that can be changed (C2, C3) may be displayed small on the left, right, etc. Thus, the display section (150) can perform the function of a course selection section (130).

[0161] The above display unit (150) may further include a status display unit (153) that displays the status of the clothing processing device. The status display unit (153) may display one or more of the internal water level status, internal temperature status, lock status, sound transmission status, and course progress status in the form of an icon.

[0162] The above option selection unit (140) may be positioned outside the course selection unit (130) or the area where the course is displayed. The above option selection unit (140) may be positioned below and spaced apart from the status display unit (153).

[0163] When the above option selection unit (140) is input, options that can be selected or adjusted may be displayed on the above display unit (150). During this process, the course selection unit (130) and the display of the course (C) may disappear.

[0164] Meanwhile, the above display unit (150) can display a device connection unit (M) that can activate the auxiliary device (5) or control the auxiliary device (5).

[0165] When the above device connection part (M) is input, the above display part (150) may be provided to receive commands related to the auxiliary device (5) while displaying the status related to the auxiliary device (5).

[0166] The above device connection part (M) may be displayed with one or more of the following: a phrase, pictogram, or icon, such as “mini” or “auxiliary device”.

[0167] FIG. 5 illustrates the appearance of an auxiliary device that may be included in the clothing processing device of the present invention.

[0168] The above auxiliary device (5) may be provided with a smaller height and volume than the above main device (4).

[0169] The above auxiliary device (5) is an auxiliary clothing processing device and may be provided to be additionally installed on the main device (4). Of course, the above auxiliary device (5) may be provided independently.

[0170] When the clothing processing device of the present invention is provided as an auxiliary device (5), the cabinet (10) may include an auxiliary cabinet (10b) having a height lower than the width in the left-right direction and the length in the front-back direction.

[0171] The above auxiliary cabinet (10b) is provided with a low height so that it can be placed at the bottom of the main device (4).

[0172] Of course, the auxiliary device (5) may be placed on the upper part of the main device (4), but for convenience of explanation, the following description is based on the auxiliary device (5) being placed on the lower part of the main device (4) or placed independently.

[0173] The above auxiliary cabinet (10b) may be provided with an auxiliary opening at the front.

[0174] The above auxiliary device (5) may further include a drawer (80) that is provided to be inserted and removed through the auxiliary opening in the above auxiliary cabinet (10b).

[0175] The drawer (80) may include a drawer body (82) that accommodates an auxiliary tub (20b) for holding water inside or a rotating auxiliary drum (30b), a drawer panel (81) positioned in front of the drawer body (81) for opening and closing the auxiliary opening, and a rail (83) that allows the drawer body (82) to be pulled in and out of the auxiliary cabinet (10b).

[0176] The drawer body (82) may be provided in the shape of a case with an open top, and may further include an auxiliary door (29) that opens or closes an auxiliary tub (20b) and an auxiliary drum (30b) inside.

[0177] The above auxiliary device (5) is equipped with a drawer (80) so that even if there is another clothing processing device or appliance on top, it can be prevented from being interfered with.

[0178] FIG. 6 illustrates an example of the internal structure when the clothing processing device of the present invention is equipped as an auxiliary device.

[0179] The above auxiliary device (5) may include an auxiliary tub (20b) that holds water inside the drawer (80), and an auxiliary drum (30b) that is rotatably provided inside the auxiliary tub (20b) and can hold clothing.

[0180] The above auxiliary tub (20b) and the above auxiliary drum (30b) may be provided with a height smaller than the diameter, and an inlet for introducing clothing may be formed at the top.

[0181] The above auxiliary device (5) may further include a water level detection unit (26b) for detecting the water level of the auxiliary tub (20b). The water level detection unit (26b) may detect the water level of the auxiliary tub (20b) by communicating with the auxiliary tub (20b) from outside the auxiliary tub (20b) and detecting a change in pressure inside the auxiliary tub (20b).

[0182] The above auxiliary device (5) may include an auxiliary door (29) coupled to the upper part of the auxiliary tub (20b) to prevent water or clothing inside the auxiliary tub (20b) from leaking out unintentionally.

[0183] Additionally, the auxiliary device (5) may include an auxiliary drive unit (40b) coupled to the auxiliary tub (20b) to rotate the auxiliary drum (30b).

[0184] The above auxiliary drive unit (40b) may be positioned at the bottom of the auxiliary tub (20b) and configured to rotate the auxiliary drum (30b).

[0185] The above auxiliary drive unit (40b) may include an auxiliary stator (41b) coupled to the lower part of the auxiliary tub (20b) to generate a rotating magnetic field, an auxiliary rotor (42b) that rotates by the auxiliary stator (41b), and an auxiliary rotating shaft (43b) that rotates by the auxiliary rotor (42b) and is coupled to the lower part of the auxiliary drum (30b).

[0186] The auxiliary device (5) of the present invention may further include an auxiliary water supply unit (50b) provided to supply water to the auxiliary tub (20b).

[0187] The above auxiliary water supply unit (50b) may include an auxiliary water supply valve (51b) coupled to an auxiliary cabinet (10b), an auxiliary water supply pipe (52b) extending from the auxiliary water supply valve (51b) to a drawer (80) to supply water, and an auxiliary box (53b) that guides the water supplied from the auxiliary water supply pipe (52b) to an auxiliary tub (20b).

[0188] The above auxiliary water supply pipe (52b) may be provided with a structure that extends forward by the length of the drawer (80) being drawn out of the auxiliary cabinet (10b). The above auxiliary box (53b) may be provided to store detergent.

[0189] The auxiliary device (5) of the present invention may further include an auxiliary drainage unit (60b) provided to drain water from the auxiliary tub (20b).

[0190] The above auxiliary drainage section (60b) may include an auxiliary discharge pipe (61b) for discharging water from the auxiliary tub (20b), an auxiliary pump (62b) coupled to the auxiliary discharge pipe (61b) to provide power for discharging water, and an auxiliary drainage pipe (63b) extending from the auxiliary pump (62b) to the outside of the auxiliary cabinet (10b).

[0191] The above auxiliary drain pipe (63b) may be provided with a structure that extends forward by the length that the drawer (80) is drawn out of the auxiliary cabinet (10b).

[0192] The above support member (70) may include an auxiliary suspension (70d) connecting the inner surface of the drawer (80) and the outer surface of the auxiliary tub (20b).

[0193] FIG. 7 illustrates an embodiment of the structure in which the auxiliary device of the present invention pulls out or locks a drawer.

[0194] When the drawer (80) is withdrawn from the auxiliary cabinet (10b), the user can put clothes into or take them out of the auxiliary drum (30b).

[0195] However, since the drawer (80) is pulled forward from the auxiliary cabinet (10b) and the auxiliary cabinet (10b) is positioned at the bottom of the main device (4), there may be the inconvenience of having to bend over excessively to pull out the drawer (80) by hand.

[0196] Accordingly, the auxiliary device (5) of the present invention may further include a withdrawal unit (87) that automatically withdraws the drawer (80) from the auxiliary cabinet (10b) when a user's withdrawal command is input.

[0197] The above-mentioned pull-out section (87) may be provided inside the auxiliary cabinet (10b) to push the drawer (80) forward a certain length. When the pull-out section (87) pushes the drawer (80) forward, the drawer (80) can be easily pulled forward by the rail (83).

[0198] The above-mentioned pull-out unit (87) can be coupled to the lower surface of the upper panel of the auxiliary cabinet (10b) and can be configured to selectively press the drawer panel (81) forward. The above-mentioned pull-out unit (87) can be configured as an electronic device capable of automatically pulling out the drawer (80) by receiving current.

[0199] The auxiliary device (5) of the present invention may further include a main control unit (851) that controls the auxiliary water supply unit (50b), the auxiliary drainage unit (60b), and the auxiliary driving unit (40b) to perform a course for processing clothing.

[0200] The main control unit (851) above may be configured to receive current and supply current to the output unit (87).

[0201] The main control unit (851) can operate the pull-out unit (87) to push the drawer panel (81) forward.

[0202] The main control unit (851) may be positioned on the back of the upper panel of the auxiliary cabinet (10b). The possibility of the main control unit (851) being interfered with by the drawing of the drawer (80) or being exposed to water contained in the tub (20) can be eliminated. The main control unit (851) may be positioned close to the auxiliary water supply valve (51b) coupled to the back of the auxiliary cabinet (10b) so that the auxiliary water supply valve (51b) can be easily controlled.

[0203] Meanwhile, even if the above-mentioned withdrawal unit (87) can withdraw the above-mentioned drawer (80), there may be various situations where the withdrawal of the above-mentioned drawer (80) from the above-mentioned auxiliary cabinet (10b) must be restricted.

[0204] For example, since safety accidents may occur while the auxiliary drive unit (40b) is driven and the auxiliary drum (30b) is rotating, it is necessary to restrict the withdrawal of the drawer (80).

[0205] Additionally, when the auxiliary tub (20b) is filled with water, if the drawer (80) is pulled out, an excessive load is applied to the rail (83), which may damage the rail (83). Also, when the auxiliary tub (20b) is filled with water, the auxiliary device (5) may tip forward due to the load of the drawer (80), including the weight of the water. Furthermore, when the auxiliary tub (20b) is filled with water, there is a risk that the water and detergent contained in the auxiliary tub (20b) may leak out of the auxiliary cabinet (10b). Therefore, when the auxiliary tub (20b) is filled with water, it is necessary to restrict the pulling out of the drawer (80).

[0206] In addition, the drawer (80) needs to be restricted from being withdrawn when water is supplied to or drained from the auxiliary tub (20b).

[0207] In addition, the drawer (80) needs to be restricted from being withdrawn when any course of processing clothing begins to be performed by the auxiliary device (5), while the course is being performed, or before the course ends.

[0208] In this way, when it is necessary to restrict the withdrawal of the drawer (80), it is necessary to set the drawer (80) to a case where withdrawal is impossible or to block the withdrawal of the drawer (80).

[0209] In the case where the withdrawal of the drawer (80) is restricted, the main control unit (851) can control the withdrawal unit (87) to block operation.

[0210] However, even if the above-mentioned pull-out unit (87) is not operated, the drawer (80) can be arbitrarily pulled forward from the auxiliary cabinet (10b) when the user pulls the drawer panel (81) forward and receives a force that pulls the drawer (80) forward due to vibrations generated in the auxiliary drum (30b).

[0211] Accordingly, in situations where the withdrawal of the drawer (80) must be restricted, the auxiliary device (5) of the present invention may need to be configured to prevent the withdrawal of the drawer (80) under any circumstances.

[0212] To this end, the auxiliary device (5) of the present invention may further include a drawer locking part (88) that fixes the drawer (80) to the auxiliary cabinet (10b) to prevent the drawer (80) from being pulled out and fixes the position where the drawer (80) is placed.

[0213] The drawer locking part (88) may be provided to be controlled by the main control unit (851) and may be provided as an electronic product capable of operating by receiving current through the main control unit (851).

[0214] For example, the drawer locking part (88) may include an actuator (881) installed on either the drawer panel (81) or the drawer body (82), and a connecting bar (882, 883) extending left and right from the actuator (881) and detachably coupled inside the auxiliary cabinet (10b).

[0215] The above connecting bar (882, 883) may be configured to reciprocate between the inner surface of the auxiliary cabinet (10b) and the actuator (881) by driving the actuator (881).

[0216] The above connecting bar (882, 883) may include a first bar (882) that extends from the actuator (881) to one side and is selectively connected to the inner surface of one side of the auxiliary cabinet (10b), and a second bar (883) that extends from the actuator (881) to the other side and is selectively connected to the inner surface of the other side of the auxiliary cabinet (10b).

[0217] When the actuator (881) is installed on the drawer panel (81), it may be positioned to the left or right of the center of the width of the drawer panel (81) to avoid interference with the auxiliary tub (20b). In this case, the first bar (882) and the second bar (883) may be provided with different lengths.

[0218] The main control unit (851) can control the actuator (881) to selectively lock the drawer (80) to the auxiliary cabinet (10b) to prevent the drawer (80) from being pulled out.

[0219] The drawer lock (88) may be controlled to unlock the drawer (80) when the withdrawal of the drawer (80) is not restricted. For example, the drawer lock (88) may be controlled to unlock the drawer (80) when the rotation of the auxiliary drum (30b) is stopped, when the water in the auxiliary tub (20b) is completely drained, and when the execution of the course is stopped.

[0220] Additionally, the withdrawal unit (87) may be operated to withdraw the drawer (80) when the withdrawal of the drawer (80) is not restricted. For example, the withdrawal unit (87) may be controlled to withdraw the drawer (80) from the auxiliary cabinet (10b) when the auxiliary drive unit (40b) has stopped rotating the auxiliary drum (30b), when the water in the auxiliary tub (20b) has been drained, and when the execution of the course has stopped.

[0221] The auxiliary device (5) of the present invention may further include a multi-functional input unit (84) disposed on the exposed surface of the drawer (80) to receive commands from a user.

[0222] The auxiliary device (5) may be configured to receive a command to control the auxiliary device (5) through the control panel (100) of the main device (4). By doing so, the user can avoid the effort of having to bend over or sit down to the height where the auxiliary device (5) is located in order to control the auxiliary device (5) located at the bottom of the main device (4).

[0223] In addition, the auxiliary device (5) may omit the installation of an independent control panel for receiving inputs such as commands for a user to select a course of the auxiliary device (5) or to perform a course. As a result, the auxiliary device (5) can form a sense of unity with the main device (4) as if they were one device.

[0224] However, since the auxiliary device (5) is configured separately from the main device (4), the auxiliary device (5) may also require a means to independently receive user commands. The auxiliary input unit (84) can perform the role of enabling the auxiliary device (5) to receive independent commands.

[0225] However, as long as the auxiliary device (5) can be controlled through the control panel (100) of the main device (4), it may not be necessary for the auxiliary input unit (84) to be provided in multiple units to receive various commands, such as the power supply unit, execution unit, selection unit, etc. of the auxiliary device (5). Therefore, the auxiliary device (5) may be provided with a smaller number of auxiliary input units (84) than the power supply unit, execution unit, selection unit, etc.

[0226] Even so, even if the auxiliary input unit (84) is provided in a number smaller than the number of commands actually received, it may be necessary to receive additional commands such as drawing out a drawer (80) unrelated to the main device (4), pairing with the auxiliary device (5), power input of the auxiliary device (5), and activation of the auxiliary device (5).

[0227] To this end, the auxiliary device (5) of the present invention may be equipped with an auxiliary input unit (84) that receives a plurality of commands as a multi-functional input unit (84).

[0228] The above multi-functional input unit (84) can be configured to receive different commands depending on the situation. That is, even if the multi-functional input unit (84) is provided as a single unit, it can be configured to receive at least two or more commands.

[0229] For example, the auxiliary device (5) of the present invention may be configured with only one multi-functional input unit (84) and configured to receive all of a plurality of commands. In this case, the multi-functional input unit (84) may be configured to receive different commands depending on the situation. Therefore, even if the multi-functional input unit (84) is provided as a single unit, it can be configured to receive variable commands depending on the situation, thereby producing the same effect as having multiple input units. Additionally, the auxiliary device (5) may omit a configuration for receiving commands separately other than the multi-functional input unit (84). Therefore, the number of multi-functional input units (84) in the auxiliary device (5) is minimized, thereby maximizing aesthetic appeal.

[0230] The above multi-functional input unit (84) may be provided in multiple units. However, even if the above multi-functional input unit (84) is provided in a single unit, multiple commands can be received and the auxiliary control unit (852) can identify them, so it is acceptable to provide it in a single unit.

[0231] The above auxiliary device (5) can be equipped with the above multi-functional input unit (84) so ​​that it can receive various commands even when not controlled by the main device (4).

[0232] The above-mentioned multi-functional input unit (84) may be provided in any configuration as long as it can receive commands from the user. For example, the above-mentioned multi-functional input unit (84) may be provided as a touch film to detect physical contact with the user, or as a button to detect the force applied by the user.

[0233] The multi-functional input unit (84) is installed on the drawer panel (81) and can always be exposed to the outside. The multi-functional input unit (84) can be installed on the front surface, which is the exposed surface of the drawer panel (81). The multi-functional input unit (84) can be positioned closer to the upper surface than the lower surface of the drawer panel (81) so that user commands can be easily received.

[0234] The above multi-functional input unit (84) can be configured to receive different commands depending on the situation, and the user can be aware of which command the multi-functional input unit (84) receives depending on each situation.

[0235] For example, the multi-functional input unit (84) may be configured to receive a power command to supply power to the main control unit (851) when the power supply to the main control unit (851) is cut off.

[0236] The above power command may include not only activating the main control unit (851) by supplying power when power is not supplied to the main control unit (851), but also a so-called wake-up command that activates the main control unit (851) so that it can operate when it is in a dormant state.

[0237] The main control unit (851) is configured to supply power to components that consume power, such as the auxiliary drive unit (40b), the auxiliary water supply valve (51b), the auxiliary drainage pump (62b), the extraction unit (87), the drawer locking unit (88), and the water level detection unit (26b).

[0238] Accordingly, when power is supplied to the main control unit (851), power is supplied to the auxiliary drive unit (40b), the auxiliary water supply valve (51b), the auxiliary drainage pump (62b), the withdrawal unit (87), the drawer locking unit (88), the water level detection unit (26b), etc., and the auxiliary device (5) can be set to a state where it can process clothing.

[0239] When the above multi-functional input unit (84) receives a power command, it can be set to supply power to at least one of the above auxiliary driving unit (40b), the above auxiliary water supply valve (51b), the above auxiliary drainage pump (62b), the extraction unit (87), the drawer locking unit (88), and the water level detection unit (26b).

[0240] The main control unit (851) may be configured to receive power from an external power source through a separate outlet, etc. Additionally, the main control unit (851) may be configured to receive power from the main device (4).

[0241] The above multi-functional input unit (84) can be set to always receive power through standby power even when power is not supplied to the main control unit (851).

[0242] The above multi-functional input unit (84) can be configured to receive commands other than the power command when power is supplied to the main control unit (851).

[0243] For example, when power is supplied to the main control unit (851), the multi-functional input unit (84) may be configured to receive a withdrawal command from the withdrawal unit (87) to withdraw the drawer (80) from the auxiliary cabinet (10b).

[0244] When the above multi-functional input unit (84) is input, the main control unit (851) considers that a withdrawal command has been received and controls the withdrawal unit (87) to withdraw the drawer (80) from the auxiliary cabinet (10b).

[0245] Of course, the main control unit (851) first determines whether the drawer (80) is in a state where it can be withdrawn, and if the withdrawal of the drawer (80) is not restricted, it can detect the input of the multi-function input unit (84) and withdraw the drawer (80) from the auxiliary cabinet (10b).

[0246] If power is supplied to the main control unit (851), in a situation where the drawer (80) is restricted from being drawn, the multi-function input unit (84) may be blocked from receiving the drawing command.

[0247] For example, if the multi-functional input unit (84) is blocked from receiving the withdrawal command, the multi-functional input unit (84) may be disabled from receiving the withdrawal command. This may mean that the multi-functional input unit (84) is switched to a state where input is impossible.

[0248] Alternatively, if the multi-functional input unit (84) is blocked from receiving the withdrawal command, it may mean that the setting is switched to receiving commands other than power commands or withdrawal commands. For example, instead of the multi-functional input unit (84) being blocked from receiving input, the multi-functional input unit (84) may be set to receive a stop command that stops the operation of the auxiliary device (5).

[0249] The above multifunction input unit (84) is in a state where power is supplied to the above main control unit (851), but in a situation where the above-mentioned drawer (80) is restricted from being drawn out of the above auxiliary cabinet (10b), it can be configured to receive a stop command to temporarily suspend the control performed by the above main control unit (851).

[0250] For example, the multi-functional input unit (84) may be configured to receive a stop command to stop the auxiliary drum (30b) when the auxiliary driving unit (40b) is rotating the auxiliary drum (30b).

[0251] As another example, when water is being supplied to the auxiliary tub (20b), the multi-functional input unit (84) may be configured to receive a stop command to close the auxiliary water supply valve (51b).

[0252] When power is supplied to the main control unit (851) and the auxiliary drive unit (40b) is in operation, the course is in operation, or water is contained in the auxiliary tub (20b), the main control unit (851) can set the input of the multi-function input unit (84) to the stop command instead of the withdrawal command.

[0253] Meanwhile, if the auxiliary device (5) is in a situation where the drawer (80) is restricted from being drawn, but the situation restricting the drawer (80) is released and the drawer (80) is allowed to be drawn again, the multi-function input unit (84) can be set to receive the drawing command.

[0254] Consequently, the multi-functional input unit (84) is configured to receive a withdrawal command for the drawer (80) when the withdrawal of the drawer (80) is not restricted, and can be configured to receive a command different from the withdrawal command when the withdrawal of the drawer (80) is restricted.

[0255] For example, the multi-functional input unit (84) may be configured to receive the stop command instead of the withdrawal command when the auxiliary drive unit (40b) is rotating the auxiliary drum (30b).

[0256] When the multi-functional input unit (84) inputs a stop command, the operation of the auxiliary drive unit (40b) is stopped, and the auxiliary drum (30b) can be stopped. Subsequently, when all situations in which the withdrawal of another drawer (80) is restricted—such as when the water in the tub (20b) is completely drained, when the inside of the tub (20b) is at an empty water level, when the course is interrupted, or when the course is not being performed—are resolved, the multi-functional input unit (84) can be set to receive the withdrawal command again. That is, the multi-functional input unit (84) can be set to receive the withdrawal command again when the withdrawal of the drawer (30) is not restricted or when the situation in which the withdrawal of the drawer (30) is restricted is resolved.

[0257] When the multi-functional input unit (84) receives the withdrawal command, the drawer locking unit (88) can be controlled to unlock the drawer (80). When the main control unit (851) deems that the withdrawal command has been received, it can control the actuator (881) to unlock the drawer (80) and operate the withdrawal unit (87) to withdraw the drawer (80) from the auxiliary cabinet (10b).

[0258] Meanwhile, the auxiliary device (5) can be controlled by the main device (4). The main device (4) can send a signal to the main control unit (851) to control the auxiliary device (5), and the main control unit (851) can control each component with a corresponding command according to the signal received from the main device (4).

[0259] However, since the auxiliary device (5) is a separate component from the main device (4) and may not be purchased together, it must first be mutually recognized or paired with the main device (4) in order to be controlled by the main device (4).

[0260] To this end, the multi-functional input unit (84) may be provided to receive a connection command that pairs the auxiliary device (5) with the main device (4).

[0261] The multi-functional input unit (84) may be configured to receive the connection command in a manner different from the stop command, withdrawal command, and power command. Thus, the multi-functional input unit (84) can receive the connection command regardless of the state of the auxiliary device (5).

[0262] For example, the above multi-functional input unit (84) can be configured so that the connection command is input when the input is maintained continuously for a certain period of time.

[0263] The main control unit (851) above may be configured to receive the connection command.

[0264] Alternatively, the auxiliary device (5) of the present invention may further include an auxiliary control unit (852) capable of detecting the input of the connection command.

[0265] Unlike the main control unit (851), the auxiliary control unit (852) can always receive power through the supply of standby power. Thus, even if power is not supplied to the main control unit (851), the multi-functional input unit (84) can receive power through the auxiliary control unit (852), and when the connection command is input, it can be transmitted to the auxiliary control unit (852).

[0266] Additionally, the multi-functional input unit (84) can be controlled by the auxiliary control unit (852). Accordingly, power commands, withdrawal commands, and stop commands input from the multi-functional input unit (84) can all be transmitted to the auxiliary control unit (852).

[0267] When the auxiliary control unit (852) receives the power command, withdrawal command, stop command, etc., it may request the main control unit (851) to execute the corresponding command.

[0268] When the main control unit (851) is not receiving power, the auxiliary control unit (852) can supply power to the main control unit (851) when the multi-function input unit (84) is input. That is, the auxiliary control unit (852) can supply power to the main control unit (851) to make the main control unit (851) capable of operating.

[0269] In addition, if the main control unit (851) does not operate for a specific period of time, or if there is no signal input to the main control unit (851) for a specific period of time, the main control unit (851) may enter a resting state that minimizes power consumption.

[0270] The auxiliary control unit (852) may request the main control unit (851) to switch back to an active state when the multi-functional input unit (84) is input.

[0271] The auxiliary control unit (852) can be connected to the multi-functional input unit (84) via a first wire (891), and the auxiliary control unit (852) can be connected to the main control unit (851) via a second wire (892).

[0272] If the main control unit (851) is connected to an external power source, the auxiliary control unit (852) can always receive power through the second wire (892) regardless of whether the main control unit (851) is not receiving power or the main control unit (851) is in a idle state.

[0273] Additionally, the auxiliary control unit (852) can supply power to the multi-functional input unit (84) via the first wire (891). The auxiliary control unit (852) can also communicate with the main control unit (851) via the second wire (892).

[0274] Additionally, the main control unit (851) can control the withdrawal unit (87) through the third wire (893) and control the drawer locking unit (88) through the fourth wire (894).

[0275] Meanwhile, the auxiliary control unit (852) may include an auxiliary communication module capable of communicating with the outside. The auxiliary communication module may be configured in any way as long as it can exchange signals with the outside via wireless methods such as Wi-Fi or Bluetooth. Thus, the auxiliary control unit (852) may communicate with the main communication module installed in the main device (4), and may also communicate with an external terminal or router.

[0276] If the above multi-functional input unit (84) is input for more than 1 second, the above auxiliary control unit (852) may be considered to have received the connection command. Accordingly, a communication module that can be connected to the auxiliary control unit (852) can be searched. In this process, if the main device (4) also receives a connection command to be connected to the above auxiliary device (5), the above main communication module (1400) can also search for the above auxiliary control unit (852).

[0277] When the auxiliary control unit (852) and the main communication module (1400) are paired and mutually recognized, all components of the auxiliary device (5) can be controlled by the control panel (100).

[0278] If the above auxiliary control unit (852) has a setting that was previously paired with the main device (4), etc., the above multifunction input unit (84) can release the setting when it receives the connection command.

[0279] That is, the auxiliary control unit (852) can be configured to be newly paired with the main device (4) by deleting all information or addresses (MAC address), etc., for recognizing the main communication module (1400) of the main device (4).

[0280] The above control panel (100) transmits a signal to the auxiliary control unit (852) to directly control all configurations of the auxiliary device (5), and the auxiliary control unit (852) transmits the signal to the main control unit (851) via the second wire (892), and the main control unit (851) can control the auxiliary device (5) according to the signal.

[0281] FIG. 8 illustrates an embodiment in which a main device and an auxiliary device are paired.

[0282] In order for the main device (4) and the auxiliary device (5) to be paired, a connection command must be input from the auxiliary device (5) through the multi-function input unit (84), and a connection command must also be input from the main device (4) through the control panel (100).

[0283] In other words, a connection command must be input to both the main device (4) and the auxiliary device (5) so that the main device (4) and the auxiliary device (5) can recognize each other and be paired. This prevents the main device (4) and the auxiliary device (5) from being arbitrarily paired with a device located in a different place or with another person's product. Additionally, it prevents the user's main device (4) and auxiliary device (5) from being arbitrarily unpaired and arbitrarily paired with another person's product.

[0284] Through the control panel (100), the user can input a connection command to set up pairing between the main device (4) and the auxiliary device (5). When the connection command is input through the control panel (100), the main communication module (1400) connected to the control panel (100) receives the connection command and can search for an auxiliary control unit (852) to set up pairing. (Step a)

[0285] When the user inputs the above multi-functional input unit (84) for a set time, a connection command can be input to the above auxiliary control unit (852). The set time can be set to 1 second or more.

[0286] When the auxiliary control unit (852) receives a connection command, it can search for the main communication module (1400) in the main device (4). (Step b)

[0287] It is acceptable for either step a or step b to be performed first. However, in order for the main device (4) and the auxiliary device (5) to be paired, both steps a and b must be completed.

[0288] When the main communication module (1400) recognizes the auxiliary control unit (852) and the auxiliary control unit (852) also recognizes the main communication module (1400), the main communication module (1400) and the auxiliary control unit (852) can check whether the other device is ready to be paired with each other. (Step c)

[0289] The main communication module (1400) can provide address information (MAC address) to the auxiliary control unit (852) so that it can recognize the main communication module (1400) and establish a mutual communication connection. The auxiliary control unit (852) can also provide address information (MAC address) to the main communication module (1400) so that it can recognize the auxiliary control unit (852) and establish a mutual communication connection.

[0290] The main communication module (1400) receives the address information (MAC address) from the auxiliary control unit (852), and can recognize that the auxiliary control unit (852) has received a connection command and that the auxiliary control unit (852) is preparing for pairing.

[0291] In addition, the auxiliary control unit (852) receives the address information (MAC address) from the main communication module (1400), and can recognize that the main communication module (1400) has received a connection command and that the main communication module (1400) is in a state of preparing for pairing.

[0292] The main communication module (1400) and the auxiliary control unit (852) can recognize the other party's address through the address information exchanged with each other and complete a pairing state that allows them to send and receive signals to and from the other party.

[0293] When the main communication module (1400) and the auxiliary control unit (852) are paired and mutually recognized, pairing can be performed immediately upon power supply without receiving a connection command or address information (MAC address).

[0294] Generally, this pairing process can be performed when the main device (4) and the auxiliary device (5) are purchased, or when either the main device (4) or the auxiliary device (5) is purchased first and then the other is purchased.

[0295] Alternatively, this pairing process may be performed when the user exchanges or changes either the main device (4) or the auxiliary device (5).

[0296] FIG. 9 illustrates an example of inputting connection information from the main device.

[0297] In the case of the above auxiliary device (5), a connection command can be received by inputting the above multi-functional input unit (84) for a set period of time, but the above main device (4) can receive a connection command through the control panel (100).

[0298] Referring to FIG. 9(a), the device connection part (M) can be displayed on the display part (150).

[0299] If the main device (4) has not been paired with the auxiliary device (5) or has been unpaired with the auxiliary device (5), the control panel (100) can receive a connection command to pair with the auxiliary device (5) by inputting the device connection part (M).

[0300] Referring to FIG. 9(b), when a connection command is input from the control panel (100), the display unit (150) can display guidance information (G) indicating that the main communication module (1400) has received address information (MAC address) from the auxiliary control unit (852).

[0301] That is, when connection information is input to the control panel (100), the main communication module (1400) can recognize the auxiliary control unit (852) and display the state of communication connection to pair with each other on the display unit (150).

[0302] The above guidance information (G) may include recognition information (G1) confirming that the auxiliary device (5) installed by the auxiliary control unit (852) that sent the address information has been recognized, and confirmation information (G2) indicating whether to actually approve pairing with the auxiliary device (5).

[0303] The above recognition information (G1) may include one or more of a phrase, icon, or pictogram indicating the type of auxiliary device (5) preparing for pairing, such as “Mini Device Confirmation”.

[0304] The above confirmation information (G2) may include one or more of a phrase, an icon, or a pictogram requesting confirmation once again whether to actually perform pairing, such as “Would you like to connect?”

[0305] The above display unit (150) may further display an approval input unit that receives a final command regarding whether to actually approve the pairing along with the above guidance information (G).

[0306] The above approval input unit may include an approval unit (Y) that receives an approval command to immediately perform the pairing, and a rejection unit (N) that receives a rejection command not to perform the pairing.

[0307] The approval section (Y) and the rejection section (N) may be displayed spaced apart from each other, and the area displayed may be configured to receive the corresponding command when input is entered.

[0308] In this way, when the main device (4) is ready to be paired with each other through the control panel (100), it displays a list of devices ready to be paired and can receive a final confirmation on whether to actually perform pairing with the corresponding device.

[0309] As a result, even if a separate display unit is omitted in the auxiliary device (5), if the multi-functional input unit (84) is input for more than a set time, the auxiliary device (5) may omit receiving a separate command until the pairing is finally completed.

[0310] Meanwhile, when the main device (4) is paired with the auxiliary device (5), if the device connection unit (M) is input, the display unit (150) can display a power unit, an execution unit, a course selection unit, an option selection unit, and guidance information (G) for controlling the auxiliary device (5).

[0311] FIG. 10 illustrates an example of the state of the control panel when the main device and the auxiliary device are paired.

[0312] The control panel (100) can display the respective status information of the main device (4) and the auxiliary device (5) in sections when the main device (4) and the auxiliary device (5) are paired.

[0313] The control panel (100) may display only the status information of the device to which a power command has been input among the main device (4) and the auxiliary device (5). In this case, the user can intuitively recognize the device currently in operation or ready to operate through the device information (I) displayed on the control panel (100).

[0314] Alternatively, the control panel (100) may display status information for both the main device (4) and the auxiliary device (5), while highlighting the status information of the device that is in a ready-to-operate or operating state after a power command has been input. In this case, the user can intuitively recognize that the main device (4) and the auxiliary device (5) are in a state where pairing is complete by seeing that both the composite information (I1) and the auxiliary information (I2) are displayed on the control panel (100).

[0315] The control panel (100) can display the status information of the main device (4) and the auxiliary device (5) by partitioning them when both the main device (4) and the auxiliary device (5) are in operation.

[0316] As illustrated, the control panel (100) can display status information of the main device (4) and the auxiliary device (5) by dividing them into left and right sections.

[0317] Alternatively, the control panel (100) may display the status information of the main device (4) and the auxiliary device (5) by dividing it vertically.

[0318] When both the main device (4) and the auxiliary device (5) are in operation, the composite information (I1) may be displayed in one section of the display unit (150). This allows the user to be informed that the information displayed in that section is status information regarding the main device (4). Additionally, the auxiliary information (I2) may be displayed in the other section of the display unit (150). This allows the user to be informed that the information displayed in that section is status information regarding the auxiliary device (5).

[0319] For example, when the power supply unit (110) is input to the main device (4) and detects the weight of the clothing stored in the drum (30), the display unit (150) can display detection information (G1) indicating that the main device (4) is detecting the weight of the clothing in the area where the composite information (I1) is displayed.

[0320] The above detection information (G1) may include one or more of a phrase, an icon, or a pictogram containing the content that the weight of the clothing is being detected, such as “weight measurement in progress.”

[0321] When the above auxiliary device (5) is performing a course such as “small amount laundry,” the display unit (150) may display one or more of the following: course information (Cm) indicating the name or type of the course being performed in the area where the above auxiliary information (I2) is displayed, time information (Tm) indicating the remaining time of the course being performed, and administration information (Gm) indicating which administration is currently being performed during the course.

[0322] Of course, even when the main device (4) is performing a course, the course information, time information, and administrative information may be displayed in the area where the composite information (I1) is displayed, and when the auxiliary device (5) is measuring weight, the detection information may be displayed in the area where the auxiliary information (I2) is displayed.

[0323] Consequently, when the main device (4) and the auxiliary device (5) are paired, the control panel (100) can be configured to display the status of both the main device (4) and the auxiliary device (5) and to receive commands to control both the main device (4) and the auxiliary device (5).

[0324] The user can control the main device (4) and the auxiliary device (5) simultaneously by operating the control panel (100), or control only the auxiliary device (5).

[0325] FIG. 11 illustrates an example of a control method in which the main device and the auxiliary device of the clothing processing device of the present invention are paired.

[0326] The clothing processing device of the present invention can perform an input step (A1) in which connection commands are input to each other from the main device (4) and the auxiliary device (5).

[0327] The above input step (A1) may include inputting an input command in a manner such as inputting a device connection part (M) to the control panel (100) of the main device (4), and inputting an input command by inputting the multi-functional input part (84) from the auxiliary device (5) for a set time or longer.

[0328] In the above input step (A1), it is irrelevant whether the input command is input first to the main device (4) or the auxiliary device (5), and the above input step (A1) can be completed when the input command is input to both the main device (4) and the auxiliary device (5).

[0329] When the above input step (A1) is completed, the main device (4) and the auxiliary device (5) can perform an information transmission step (A2) to send information, programs, etc. that can be mutually recognized and communicated.

[0330] The above information transmission step (A2) may include the main device (4) searching for a device capable of pairing, and if the device is found, sending recognition information including address information (MAC address) that can be connected to the main communication module (1400).

[0331] Additionally, the information transmission step (A2) may include the auxiliary device (5) searching for a device capable of pairing, and if the device is found, sending recognition information including address information (MAC address) that can be connected to the auxiliary control unit (852).

[0332] When the above information transmission step (A2) is completed, the main device (4) and the auxiliary device (5) can perform a verification step (A3) to check whether communication is connected with the counterpart device that recognizes each other and exchanges recognition information, and whether communication is continuously possible.

[0333] In the above verification step (A3), the main device (4) can check whether it is in a state where it can not only connect to communication in real time from the auxiliary device (5) but also continuously send and receive signals, and the auxiliary device (5) can check whether it is in a state where it can not only connect to communication in real time from the main device (4) but also continuously send and receive signals.

[0334] In the above verification step (A3), it is confirmed that the main device (4) and the auxiliary device (5) have mutually recognized and that a normal communication state is established where communication is connected and signals can be exchanged, and an approval step (A4) may be performed to finally review whether to set up pairing between the main device (4) and the auxiliary device (5).

[0335] Since the above auxiliary device (5) does not have a separate configuration for receiving a command regarding whether to approve pairing, the approval step (A4) can be performed on the main device (4) or an external terminal, etc.

[0336] The above approval step (A4) may include inputting an area corresponding to either the approval section (Y) or the rejection section (N) among the approval input sections displayed on the display section (150) of the control panel (100).

[0337] Alternatively, the approval step (A4) may be applied in any way that can verify whether pairing with the auxiliary device (5) is actually performed.

[0338] When the approval input is received in the approval step (A5) above, a decision step (A5) can be performed to determine whether to actually perform pairing or stop pairing.

[0339] The above decision step (A5) may include a confirmation step (A5-1) in which the approval part (Y) is input in the approval step (A4) to set and maintain the pairing of the main device (4) and the auxiliary device (5), and a release step (A5-2) in which the rejection part (N) is input in the approval step (A4) to release the pairing of the main device (4) and the auxiliary device (5) and also release the communication connection.

[0340] When the above confirmation step (A5-1) is performed, the main communication module (1400) of the main device (4) and the auxiliary control unit (852) of the auxiliary device (5) can store mutual recognition information.

[0341] If the main communication module (1400) and the auxiliary control unit (852) are configured to use standby power, the communication connection state can always be maintained.

[0342] If the main communication module (1400) and the auxiliary control unit (852) are configured to have power cut off and then restored, they may be automatically paired by mutually recognizing each other through the address information.

[0343] When the above release step (A5-2) is performed, the main communication module (1400) of the main device (4) and the auxiliary control unit (852) of the auxiliary device (5) can delete recognition information including address information received from each other.

[0344] FIG. 12 illustrates an example of a control method in which pairing is released in an auxiliary device of the present invention.

[0345] Unpairing can be done on the premise that pairing has already been established.

[0346] Accordingly, once the main device (4) and the auxiliary device (5) are paired, a maintenance step (B1) is performed to maintain the paired state without taking any special measures thereafter.

[0347] However, a verification step (B2) to check whether a connection command is input again in the above auxiliary device (5) can also be performed simultaneously.

[0348] When the connection command is entered in the above verification step (B2), the auxiliary device (5) can be considered to be preparing to perform pairing again or to pair with another device.

[0349] Even though the auxiliary device (5) is already paired with the main device (4), if the multi-functional input unit (84) is input again for a set time or longer, the auxiliary control unit (852) can perform a release step (B3) to release the pairing with the main communication module (1400). When the release step (B3) is performed, the main communication module (1400) can also recognize that the pairing has been released and can transmit information that the pairing has been released to the control panel (100).

[0350] The control panel (100) can notify the fact that pairing has been unpaired through the display unit (150).

[0351] When the above release step (B3) is performed, the auxiliary control unit (852) can perform a deletion step (B4) that deletes recognition information including the address information of the main device (4) that was previously received. By doing so, the auxiliary control unit (852) can return to a state for pairing with a new device.

[0352] The release step (B3) and the deletion step (B4) may be limited to those related to the pairing of the main device (4). That is, if the auxiliary control unit (852) is paired with an external terminal, the release of the pairing can be performed at the external terminal.

[0353] The present invention may be modified and implemented in various forms, and its scope of rights is not limited to the embodiments described above. Therefore, if a modified embodiment includes the components of the claims of the present invention, it should be considered to fall within the scope of rights of the present invention.
