[0109] According to one embodiment, the water level sensor (271) is a sensor configured to detect the water level within the tub (120). The water level sensor (271) may be positioned, for example, at the lower side of the tub (120) to detect a pressure difference according to the water level of water introduced into the tub (120) as an electrical signal. In one embodiment, the water level sensor (271) may be positioned to detect the water level in a water supply situation. In one embodiment, the water level sensor (271) may be positioned to detect the progress of water drainage when draining water at the latter part of a washing cycle or a rinsing cycle. The water level sensor (271) may transmit an electrical signal regarding the water level within the tub (120) to the control unit (220).

[0110] A current sensor (272) may be arranged to detect the current flowing in the motor (150). An electrical signal regarding the current value of the motor (150) generated by the current sensor (272) may be transmitted to the control unit (220). The control unit (220) may use the current sensor (272) to detect the load applied to the motor (150) when the motor (150) rotates, and based on this, estimate or calculate the weight of clothing contained in the rotating drum (130).

[0111] A door sensor (273) may be positioned to determine whether the door (114) is closed before the control unit (220) performs a washing operation. An electrical signal generated by the door sensor (273) regarding whether the door (114) is open or closed may be transmitted to the control unit (220).

[0112] The speed sensor (274) may be arranged to detect the rotational speed, rotational angle, or rotational direction of the motor (150) or the rotating drum (130). In one embodiment, the speed sensor (274) may utilize a method of detecting the position of the rotor and the on / off signal of an adjacent hall sensor while the motor (150) is driven, for example. In one embodiment, the speed sensor (274) may utilize a method of measuring the magnitude of the current applied to the motor (150) while the rotating drum (130) is rotating.

The control unit (220) may include a memory (221) that stores or memorizes programs and / or data for controlling each component of the garment treatment device (100), and a processor (222) that generates a control signal for controlling each component of the garment treatment device (100) based on the programs and / or data stored in the memory (221) and information obtained from each of the other components.

[0116] According to one embodiment, the memory (221) can store various data that can be used to control the operation of each component of the garment treatment device (100). The memory (221) can store, for example, a plurality of application programs used in the garment treatment device (100), data for controlling the operation of the garment treatment device (100), and commands. At least some of the application programs stored in the memory (221) can be downloaded from an external server via wireless communication. At least some of the application programs stored in the memory (221) can be stored in the memory (221) from the time of shipment for the basic function of the garment treatment device (100). In one embodiment, the memory (221) can store information on a change in natural frequency according to an additional weight applied to the upper portion of the garment treatment device (100), as will be described later.

[0117] In one embodiment, the processor (222) of the control unit (220) may receive various input / setting information, such as power on / off of the garment treatment device (100), garment treatment device operation setting information (e.g., operation start / stop, course selection, time selection, etc.) or other various control information, from the input unit (210) and / or the communication unit (260) described above. The processor (222) may obtain various detection information from the sensor unit (270), such as information on the water level in the tub (120) detected by the water level sensor (271), information on the current flowing in the motor (150) detected by the current sensor (272), information indicating whether the door is open or closed detected by the door sensor (273), information on the rotation speed of the motor (150) or the rotating drum (130) detected by the speed sensor (274), and information on the internal water temperature detected by the temperature sensor (275). The processor (222) can obtain, for example, information indicating the amount of vibration of the rotating drum (130) from a vibration sensor (276) to estimate or obtain an eccentricity value of the rotating drum (130). The processor (222) can obtain, for example, information regarding the weight additionally applied to the garment treatment device (100), including the weight of the garment treatment device (100) itself, from a load sensor (277).

[0118] In one embodiment, the processor (222) of the control unit (220) may generate an operation control command for each component of the clothing treatment device (100) based on various pieces of information received from the input unit (210), the communication unit (260), and / or the sensor unit (270). In one embodiment, the processor (222) may control each component related to performing at least one of a washing cycle, a rinsing cycle, a dehydration cycle, or a drying cycle. The processor (222) may control the operation of, for example, a motor (150), a water supply device (105), and / or a drain pump (240) to control the performance of at least one of the washing cycle, the rinsing cycle, the dehydration cycle, or the drying cycle. In one embodiment, the processor (222) may control the driving of the motor (150) to rotate the rotating drum (130). For example, the processor (222) can control the opening and closing of the water supply valve (230) of the water supply device (105) to adjust the washing water supplied to the rotating tub (130) and / or the tub (120). For example, the processor (222) can control the drain valve (123) and / or the drain pump (240) to drain the washing water in the rotating tub (130) and / or the tub (120). In one embodiment, the processor (222) can continuously obtain information from the input unit (210), the communication unit (260) and / or the sensor unit (270) while performing at least one of the washing cycle, the rinsing cycle, the dehydration cycle or the drying cycle, and can continuously update and control the operation of each component based on the obtained information.

[0119] In one embodiment, the processor (222) of the control unit (220) may generate a command to control whether and how information is displayed through the display unit (250) based on various pieces of information received from the input unit (210), the communication unit (260), and / or the sensor unit (270).

[0120] According to one embodiment, the processor (222) of the control unit (220) may measure the total weight applied to the load sensor (277), including the weight of the garment treatment device (100), using the load sensor (277). According to one embodiment, the processor (222) may calculate a first weight applied to the garment treatment device (100) from the upper side of the garment treatment device (100) using the load sensor (277). Here, the first weight may refer to a weight applied to the garment treatment device (100) by an object loaded on the garment treatment device (100) by a user or due to the installation environment of the garment treatment device. For example, in the case of a drum-type garment treatment device (100), a dryer may be loaded on top, and other objects may be placed thereon according to the user's convenience. As the first weight is applied to the garment treatment device (100), the natural frequency of the garment treatment device (100) may vary. For example, as the first weight applied from the upper side of the garment treatment device (100) increases, the natural frequency of the garment treatment device (100) may decrease.

[0121] According to one embodiment, the processor (222) of the control unit (220) can estimate or calculate the first weight periodically or aperiodically. The processor (222) can estimate or calculate the first weight periodically or aperiodically when the garment treatment device (100) is not in operation. For example, the processor (222) can measure the total weight applied to the garment treatment device (100) using a plurality of load sensors (277). The processor (222) can estimate or calculate the first weight by subtracting the weight of the garment treatment device (100) itself from the total weight. Here, the weight of the garment treatment device (100) itself can be measured in advance and stored in the memory (221). The processor (222) can calculate the first weight at predetermined time intervals to determine whether an object is loaded on the garment treatment device (100). The calculated first weight can be stored in the memory (221).

[0122] According to one embodiment, the processor (222) of the control unit (220) can calculate the first weight at the beginning of the dehydration process. The processor (222) can calculate the first weight using the load sensor (277) after the dehydration process starts. When the dehydration process starts after the rinsing process is completed, the processor (222) can estimate or calculate the weight of the wet cloth while the clothes (or laundry) (hereinafter referred to as “wet cloth”) soaked in water are accommodated in the rotating drum (130). In one embodiment, under the control of the processor (222), the rotating drum (130) can be rapidly accelerated in the forward and reverse directions, and the load generated in the motor (150) during the rapid acceleration in the forward and reverse directions can be estimated or calculated. The load generated in the motor (150) can be estimated or calculated by the intensity of the current detected by the current sensor (272). As the intensity of the current flowing through the motor (150) increases when the rotating drum (130) rapidly accelerates in the forward or reverse direction, the weight of the wet cloth may increase. The processor (222) may estimate or calculate the weight of the wet cloth using the intensity of the current detected when the rotating drum (130) rapidly accelerates in the forward or reverse direction. Hereinafter, the weight of the wet cloth estimated or calculated by the processor (222) in the dehydration process is referred to as the second weight.

[0123] The processor (222) can measure the total weight applied to the clothing treatment device (100) using a plurality of load sensors (277) at the beginning of the dehydration process. The processor (222) can calculate the first weight by subtracting the weight of the clothing treatment device (100) itself and the second weight from the total weight. Here, the weight of the clothing treatment device (100) itself may be stored in the memory (221) in a pre-measured state. The first weight applied to the clothing treatment device (100) (or the weight of the object(s) loaded on the upper side of the clothing treatment device (100)) can be estimated or calculated at the beginning of the dehydration process before the rotating drum (130) rotates at high speed. If the first weight is estimated or calculated while the clothing treatment device (100) is not in operation, the accuracy may be reduced because the first weight is estimated or calculated while the user has placed clothing or laundry in the drum. The first weight estimated or calculated at the beginning of the dehydration process is the weight estimated or calculated immediately before high-speed rotation, and is a value estimated or calculated by considering the weight of the wet cloth contained in the rotating tank (130), and can have relatively high accuracy.

[0124] According to one embodiment, the processor (222) of the control unit (220) may estimate or calculate the resonant rotation speed of the garment treatment device (100) based on the first weight estimated or calculated by one of the aforementioned methods. The processor (222) may, for example, estimate or calculate the amount of change in the resonant rotation speed of the garment treatment device (100) according to the size of the first weight. The processor (222) may, for example, estimate or calculate the amount of change in the natural frequency of the garment treatment device (100) according to the size of the first weight. A method of estimating or calculating the resonant rotation speed of the garment treatment device (100) based on the first weight will be described later with reference to FIGS. 5A and 5B. In this document, the 'resonant rotation speed' is a value based on the natural frequency of the garment treatment device (100) and may refer to the rotation speed of the rotating drum (130) capable of generating resonance in the garment treatment device (100). In this document, the resonant rotation speed is indicated as a specific value without a range being provided, but those skilled in the art will be able to understand that resonance can occur in the clothing treatment device (100) within a predetermined range from the resonant rotation speed. In this document, a range within a predetermined range from the resonant rotation speed is referred to as a 'resonant rotation range'. For example, resonance can occur for a range within 100 RPM from the resonant rotation speed value. For example, when the resonant rotation speed of the clothing treatment device (100) is referred to as a specific value of 1000 RPM, resonance can occur in the clothing treatment device (100) when the rotation speed of the rotating drum (130) is between 900 RPM and 1100 RPM. In this case, the resonant rotation range is 900 RPM to 1100 RPM. However, the size of the rotation speed range that generates resonance is not limited thereto.

[0125] In this drawing, the control unit (220) is disclosed as a single comprehensive configuration that controls all of the components included in the garment treatment device (100), but this document is not limited thereto. In one embodiment, the garment treatment device (100) may be configured to include a plurality of control unit configurations that individually control some of the components of the garment treatment device (100). In one embodiment, the garment treatment device (100) may include a separate control unit having a processor and a memory for controlling the operation of the motor (150). In one embodiment, the garment treatment device (100) may include a separate control unit having a processor and a memory for controlling the operation of a user interface according to a user input. The processor (222) of the control unit (220) may include a plurality of processors, and the memory (221) may include a plurality of memory devices.

[0126] Figure 4 is a rear view of a washing machine according to one embodiment.

[0127] Figure 5 is an enlarged view of area A of Figure 4.

[0128] Any of the features, components, and / or arrangement relationships between components illustrated in FIGS. 4 and 5 may be incorporated, alone or in combination, into the features, components, and arrangement relationships between components described in other drawings of this specification. Likewise, any of the features, components, and / or arrangement relationships between components described with respect to FIGS. 1 to 3 and FIGS. 6 to 11 may be incorporated, alone or in combination, into the features, components, and arrangement relationships between components described in FIGS. 4 and 5.

[0129] The garment treatment device (100) illustrated in FIGS. 4 and 5 may be substantially the same as or similar to the garment treatment device of FIGS. 1 and 2 (e.g., the garment treatment device (100) of FIG. 1). The components illustrated in FIGS. 4 and 5 may be included in the garment treatment device of FIGS. 1 and 2 (e.g., the garment treatment device (100) of FIG. 1). Among the components of FIGS. 4 and 5, the same reference numerals are used for components that are substantially the same as or similar to the components illustrated in FIGS. 1 and 2.

[0130] Referring to FIGS. 4 and 5, the garment treatment device (100) may include a side frame (112) and a lower frame (113).

[0131] According to one embodiment, the lower frame (113) may include at least one through hole (1131). The at least one through hole (1131) may be formed in the rear portion (113d) of the lower frame (113). The at least one through hole (1131) may be formed to face rearward in the lower frame (113). For example, one of the plurality of through holes (1131) may be formed in the rear portion (113d) of the lower frame (113), and another of the at least one through hole (1131) may be formed in the front portion (113a), the left side portion (113b), or the right side portion (113c) of the lower frame (113), unlike as illustrated.

[0132] The worker can use the through hole (1131) to connect the damping device (170) and the lower frame (113). The damping device (170) can be fastened to the lower frame (113) by inserting a tool into the main body (110) through the through hole (1131).

[0133] According to one embodiment, at least one through hole (1131) may include a first through hole (1131a) and a second through hole (1131b). The number of through holes (1131) may correspond to the number of damping devices (170) included in the garment treatment device (100). For example, when two damping devices (170) are arranged, two through holes (1131) may be formed.

[0134] According to one embodiment, the first through hole (1131a) and the second through hole (1131b) may be formed on the same plane. For example, the first through hole (1131a) and the second through hole (1131b) may be formed on the rear surface (113d) of the lower frame (113). The first through hole (1131a) and the second through hole (1131b) may be formed to be adjacent to each other. By forming the first through hole (1131a) and the second through hole (1131b) on the same plane, the inconvenience of rotating the lower frame (113) or moving the worker when assembling the damping device (170) and the lower frame (113) using the through hole (1131) can be reduced. Consequently, by forming the first through hole (1131a) and the second through hole (1131b) on the same plane, the assembly efficiency of the worker can be improved.

[0135] FIG. 6 is a plan view illustrating a lower frame and a damping device of a washing machine according to one embodiment.

[0136] Figure 7 is a plan view of the lower frame of a washing machine according to one embodiment.

[0137] Figure 8 is an enlarged perspective view of area B of Figure 6.

[0138] Figure 9 is a partial development view of Figure 8.

[0139] Any of the features, components, and / or arrangement relationships between components depicted in FIGS. 6 through 9 may be incorporated, alone or in combination, into the features, components, and arrangement relationships between components described in other drawings of this specification. Likewise, any of the features, components, and / or arrangement relationships between components described with respect to FIGS. 1 through 5 and FIGS. 10 through 11 may be incorporated, alone or in combination, into the features, components, and arrangement relationships between components described in FIGS. 6 through 9.

[0140] The configurations illustrated in FIGS. 6 to 9 may be included in the garment treatment device of FIGS. 1 and 2 (e.g., the garment treatment device (100) of FIG. 1). Among the configurations of FIGS. 6 to 9, the same reference numbers are used for configurations that are substantially the same or similar to the configurations illustrated in FIGS. 1 and 2.

[0141] Referring to FIGS. 6 to 9, the garment treatment device (100) may include a lower frame (113) and a damping device (170). The lower frame (113) may be formed with an open center, but is not limited thereto.

[0142] According to one embodiment, the lower frame (113) may include a through hole (1131) and a guide portion (1132).

[0143] According to one embodiment, the guide portion (1132) may extend from the through hole (1131). The guide portion (1132) may extend from the through hole (1131) toward the fastening portion (180). The guide portion (1132) may extend from the through hole (1131) toward a portion where the damping device (170) and the lower frame (113) are coupled. The guide portion (1132) may be configured to guide a path along which a tool enters when a worker performs work. The guide portion (1132) may be referred to as a guide rail.

[0144] According to one embodiment, the guide portion (1132) may be formed to extend along the fastening direction of the fastening portion (180). Here, the fastening direction of the fastening portion (180) may refer to the direction in which the fastening portion (180) is fastened to fasten the lower frame (113) and the damping device (170). Here, the fastening direction of the fastening portion (180) may refer to the longitudinal direction of the fastening portion (180) when the fastening portion (180) is fastened.

[0145] According to one embodiment, a plurality of guide portions (1132) may be formed. The guide portions (1132) may be arranged to correspond to the number of through holes (1131). The guide portions (1132) may be arranged to correspond to the number of damping devices (170).

[0146] According to one embodiment, the guide portion (1132) may be formed to guide the path through which a tool for fastening the fastening portion (180) enters. A through hole (1131) may be formed so that a worker can access the inside of the main body (110) to fasten the lower frame (113) and the damping device (170). In this case, if there is a distance between the fastening position and the through hole (1131), the worker has to rely on his or her senses without sight to find the fastening position, which is inconvenient. In the present disclosure, the guide portion (1132) is formed so that the worker can more conveniently find the fastening position. The worker can easily find the fastening position by inserting the tool and the fastening portion (180) along the guide portion (1132).

[0147] According to one embodiment, the guide portion (1132) may be configured to be connected to the lower portion of the edge of the through hole (1131). The guide portion (1132) may be formed integrally with the through hole (1131). For example, the guide portion (1132) may be formed integrally with the lower portion of the edge of the through hole (1131).

[0148] According to one embodiment, the guide portion (1132) may have a semicircular cross-section. For example, the guide portion (1132) may be formed as a curved surface having a predetermined curvature. For example, the guide portion (1132) may have a shape that is recessed downward. However, the present invention is not limited thereto, and may have a cross-section in the shape of a polygon cut in half.

[0149] According to one embodiment, the guide portion (1132) may be formed with an open upper portion. However, this is not limited thereto, and a portion of the upper portion of the guide portion (1132) may be covered.

[0150] According to one embodiment, the guide portion (1132) may extend horizontally as illustrated, but is not limited thereto, and may be formed to slope upward or downward from the through hole (1131) toward the damping device (170). For example, when the position at which the fastening portion (180) is fastened is positioned upward or downward relative to the center of the through hole (1131), the guide portion (1132) may be formed to slope upward or downward to compensate for the height difference.

[0151] According to one embodiment, the guide portion (1132) may be formed so that one end is in contact with the through hole (1131) and the other end is adjacent to the portion where the fastening portion (180) is fastened. The other end of the guide portion (1132) may be formed so as to be adjacent to the joining portion (1133) of the lower frame (113).

Similarly, any of the features, components, and / or arrangement relationships between components described with respect to FIGS. 1 through 9 may be incorporated, alone or in combination, into the features, components, and arrangement relationships between components described in FIGS. 10 and 11.

[0161] The lower frame (1000) and damping device (170) illustrated in FIGS. 10 and 11 may be included in the garment treatment device (100) of FIGS. 1 and 2. The same reference numbers are used for configurations substantially identical or similar to those described in FIGS. 6 to 9 among the configurations of FIGS. 10 and 11.

[0162] Referring to FIGS. 10 and 11, the garment treatment device (100) may include a lower frame (1000) and a damping device (170). The lower frame (1000) may be formed with an open center, but is not limited thereto.

[0163] According to one embodiment, the lower frame (1000) may include a through hole (1131) and a guide portion (1020).

[0164] According to one embodiment, the guide portion (1020) may extend from the through hole (1131). The guide portion (1020) may extend from the through hole (1131) toward the fastening portion (180). The guide portion (1020) may extend from the through hole (1131) toward a portion where the damping device (170) and the lower frame (1000) are coupled. The guide portion (1020) may be configured to guide a path along which a tool enters when a worker performs work. The guide portion (1020) may be referred to as a guide rail.

[0165] According to one embodiment, the guide portion (1020) may be formed to extend along the fastening direction of the fastening portion (180). Here, the fastening direction of the fastening portion (180) may refer to the direction in which the fastening portion (180) is fastened to fasten the lower frame (1000) and the damping device (170). Here, the fastening direction of the fastening portion (180) may refer to the longitudinal direction of the fastening portion (180) when the fastening portion (180) is fastened.

[0166] According to one embodiment, a plurality of guide portions (1020) may be formed. The guide portions (1020) may be arranged to correspond to the number of through holes (1131). The guide portions (1020) may be arranged to correspond to the number of damping devices (170).

[0167] The guide portion (1020) may be formed to guide the path through which a tool for fastening the fastening portion (180) enters. A through hole (1131) may be formed to allow a worker to access the interior of the main body (110) to fasten the lower frame (1000) and the damping device (170). In this case, if there is a distance between the fastening position and the through hole (1131), the worker has to rely on his or her senses without a field of vision, which is inconvenient. In the present disclosure, the guide portion (1020) is formed to enable the worker to more conveniently find the fastening position. The worker can easily find the fastening position by inserting the tool and the fastening portion (180) along the guide portion (1020).

[0168] According to one embodiment, the guide portion (1020) may be configured to be connected to the lower portion of the edge of the through hole (1131). The guide portion (1020) may be formed integrally with the through hole (1131). For example, the guide portion (1020) may be formed integrally with the lower portion of the edge of the through hole (1131).

[0169] According to one embodiment, the guide portion (1020) may have a semicircular cross-section. For example, the guide portion (1020) may be formed as a curved surface having a predetermined curvature. For example, the guide portion (1020) may have a shape that is recessed downward. However, the present invention is not limited thereto, and may have a cross-section in the shape of a polygon cut in half.

[0170] According to one embodiment, the guide portion (1020) may be formed to have a variable width. The guide portion (1020) may be configured to have a width (or radius) that decreases from the through hole (1131) toward the damping device (170). The guide portion (1020) may be configured to have a width that decreases from the through hole (1131) toward the fastening portion (180). The width of a portion of the guide portion (1020) adjacent to the damping device (170) may be smaller than the diameter of the through hole (1131). For example, the guide portion (1020) may be formed to have a surface curvature that increases from the through hole (1131) toward the damping device (170). By forming a wider through hole (1131) in this way, a worker can more easily insert a tool. In addition, by reducing the width of the guide portion (1020) from the through hole (1131) to the damping device (170), the tool can be guided to advance toward the fastening portion (180).

[0171] According to one embodiment, the guide portion (1020) may be formed with an open upper portion. However, this is not limited thereto, and a portion of the upper portion of the guide portion (1020) may be covered.

[0172] According to one embodiment, the guide portion (1020) may extend horizontally as illustrated, but is not limited thereto, and may be formed to slope upward or downward from the through hole (1131) toward the damping device (170). For example, when the position at which the fastening portion (180) is fastened is positioned upward or downward relative to the center of the through hole (1131), the guide portion (1020) may be formed to slope upward or downward to compensate for the height difference.

[0173] According to one embodiment, the guide portion (1020) may be formed such that one end is in contact with the through hole (1131) and the other end is adjacent to the portion where the fastening portion (180) is fastened. The other end of the guide portion (1020) may be formed such that it is adjacent to the joining portion (1133) of the lower frame (1000). The other end of the guide portion (1020) may be positioned so as to be spaced apart from the joining portion (1133) of the lower frame (1000).

[0174] According to various embodiments proposed in the present disclosure, a garment treatment device can provide a structure in which a through hole is formed in a lower frame and a guide portion extending inward from the through hole is formed, thereby allowing an operator to easily access a fastening portion by entering a tool along the guide portion when entering the tool through the through hole.

[0175] Although the foregoing description in this disclosure has focused on specific embodiments, it should be understood that this disclosure is not limited to such specific embodiments, but rather encompasses various modifications, equivalents, and / or alternatives of the various embodiments.
