Description

Garment treatment device and method for controlling the garment treatment device

[0001] This application relates to a clothing treatment device and a method for controlling the clothing treatment device.

[0002] A clothing treatment device is a general term for a washing machine that washes laundry items, a dryer that dries laundry items, and a device that can perform both washing and drying of clothing (a general term for laundry items or / and drying items).

[0003] Washing machines are generally equipped with a tub for storing water, a drum provided inside the tub for storing clothes, and a driving unit for rotating the drum, and dryers are generally equipped with a drum for storing clothes, a driving unit for rotating the drum, and a heat exchanger for supplying air to the drum to remove moisture from the clothes.

[0004] Some conventional clothing treatment devices have been equipped with a sensing unit for measuring the dryness of clothing (Korean Patent No. 10-0747589). The sensing unit comprises a sensing circuit connecting two electrodes positioned at separate points. With the two electrodes connected by the clothing, voltage is applied to the sensing circuit to determine the dryness of the clothing (the amount of moisture remaining in the clothing). In other words, conventional sensing units utilize the phenomenon in which the resistance of the sensing circuit varies depending on the amount of moisture remaining in the clothing to determine the dryness.

[0005] However, the aforementioned sensing unit can easily determine dryness when the amount of water remaining in the clothing is large (when the dryness level is low), but has the disadvantage of being difficult to detect changes in dryness when the amount of water remaining in the clothing is small (when the dryness level is high). This is because the higher the dryness level, the smaller the change in the amount of water remaining in the clothing, making it difficult to determine whether the dryness level has changed.

[0006] The present application aims to provide a clothing treatment device and a method for controlling the clothing treatment device that measure the dryness level through different sensing units depending on the progress of the drying stage.

[0007] In addition, the present application aims to solve the problem of providing a clothing treatment device and a method for controlling the clothing treatment device that detects the dryness level through contact with the object to be dried in the initial drying stage and measures the dryness level by detecting heat emitted from the object to be dried in the later drying stage.

[0008] In addition, the present application aims to solve the problem of providing a clothing treatment device capable of accurately detecting dryness and a method for controlling the clothing treatment device.

[0009] The present application relates to a control method for a clothing treatment device having a receiving unit that provides a space for receiving an object to be dried, a heat exchange unit that removes water from the object to be dried, a first sensing unit that contacts the object to be dried and detects the dryness of the object to be dried, and a second sensing unit that detects the dryness of the object to be dried by detecting heat emitted from the object to be dried.

[0010] The above control method may include a drying step of operating the heat exchanger while the receiving unit rotates; a sensing step of determining the dryness of the object to be dried through the first sensing unit and the second sensing unit during the drying step; a first judgment step of determining through the first sensing unit whether the dryness of the object to be dried has reached a reference dryness level set lower than the target dryness level; and a second judgment step of determining through the second sensing unit whether the dryness of the object to be dried has reached the target dryness level when the dryness of the object to be dried has reached the reference dryness level.

[0011] The above standard dryness can be set to 70% to 90% of the above target dryness.

[0012] The above first judgment step may be initiated when the execution time of the drying step reaches a preset execution reference time.

[0013] The above first judgment step can determine that the dryness of the object to be dried is higher than the standard dryness if the state of being higher than the standard dryness is maintained for a preset first duration of time.

[0014] The second judgment step may determine that the dryness of the object to be dried has reached the target dryness if the state of reaching the target dryness is maintained for a preset second duration.

[0015] The above control method may further include a load determination step for determining the amount of the drying object inside the receiving unit; and an execution time setting step for setting the execution time of the drying step according to the measured load.

[0016] When the remaining time required to reach the above execution time reaches the preset standard remaining time and the dryness measured by the second detection unit is less than the target dryness, the control method can terminate the drying step.

[0017] When the remaining time reaches the reference remaining time and the dryness measured by the second detection unit is less than the target dryness, the control method may further include a setting time adjustment step of increasing the setting time by a preset additional time.

[0018] The above drying step may be terminated when the execution time of the above drying step reaches the adjusted set time.

[0019] The above first detection unit can determine the dryness level through the resistance or impedance measured when voltage is applied to a detection circuit connecting two electrodes arranged to be spaced apart from each other.

[0020] The second detection unit can determine the dryness level by detecting infrared rays reflected from or emitted from the drying object.

[0021] The present application provides a method for controlling a clothes treatment device, including: a drying step of removing water from an object to be dried by supplying air to a receiving unit while the receiving unit, in which the object to be dried, rotates; a sensing step of determining the dryness of the object to be dried through a first sensing unit that generates a control signal based on the amount of water remaining in the object to be dried and a second sensing unit that generates a control signal based on heat emitted from the object to be dried; a first judgment step of determining through the first sensing unit whether the dryness of the object to be dried has reached a reference dryness level set lower than a target dryness level; and a second judgment step of determining through the second sensing unit whether the dryness of the object to be dried has reached the target dryness level when the dryness of the object to be dried has reached the reference dryness level.

[0022] The present application provides a clothing treatment device that measures the dryness level through different sensing units according to the progress of the drying stage, and a method for controlling the clothing treatment device.

[0023] In addition, the present application provides a clothing treatment device and a method for controlling the clothing treatment device that detects the dryness level through contact with the object to be dried in the initial drying stage and measures the dryness level by detecting heat emitted from the object to be dried in the later drying stage.

[0024] In addition, the present application provides a clothing treatment device capable of accurately detecting dryness and a method for controlling the clothing treatment device.

[0037] The drum inlet (142) may be provided to be connected to the cabinet inlet (111). Accordingly, when the door (115) opens the cabinet inlet (111), the user can insert clothes into the drum body (171) or take clothes out from the drum body (171) through the cabinet inlet (111) and the drum inlet (142).

[0038] In order to filter the air discharged from the drum body (171), a filter (19, see FIG. 2) that can be attached to the front panel body (141) may be provided in the drum exhaust hole (143).

[0039] The front panel (14) may be provided with a front support body (144) that rotatably supports the front surface of the drum body (171). The front support body (144) may be provided as a ring-shaped tube that surrounds the drum inlet (142). That is, the front support body (144) may be provided as a pipe with a diameter longer than the diameter of the drum inlet (143), and the drum inlet (142) may be provided to be positioned inside the front support body (144). Unlike the above, the front support body (144) may be provided by arranging a plurality of plates (front protruding plates) to form a ring that surrounds the drum inlet (142).

[0040] The rear panel (15) may be provided to include a rear panel body (151) fixed to the rear surface (12) or the cabinet (1), and a drum supply hole (152) provided to penetrate the rear panel body (151).

[0041] As illustrated in Fig. 2, the rear panel (15) may be provided with a rear support body (153) that rotatably supports the rear surface of the drum body (171). The rear support body (153) may be provided as a ring-shaped tube that protrudes from the rear panel (15) toward the drum body (171). In this case, the drum supply hole (152) may be provided to be located inside the rear support body (153). Unlike the above, the rear support body (144) may also be provided by arranging a plurality of plates (rear protruding plates) to form a ring.

[0042] As illustrated in Fig. 3, the drum body (171) can be rotated by a driving unit (18) provided inside the cabinet (1). The driving unit (18) may be provided with a drum motor (181) fixed to the base (13), and a belt (182) connecting the rotational axis of the drum motor and the circumference of the drum body (171).

[0043] In order to stir the clothes inside the drum body (171), a lifter (172) may be further provided inside the drum body (171). The lifter (172) may be provided as a board protruding from the circumference of the drum body (171) toward the center of rotation of the drum body.

[0044] Unlike the above, the drum body (171) may be provided in a cylindrical shape with an open front and a closed rear. In this case, the rear panel (15) may be omitted. However, the rear surface of the drum body (171) may be rotatably supported on the rear surface (12) of the cabinet, etc., via a rotational axis, and the drum supply hole (152) may be provided as a plurality of through holes penetrating the rear surface of the drum body (171).

[0045] The drum body (171) may be provided in a cylindrical shape with both the front and rear sides closed. In this case, the drum inlet (142) must be provided on the front side of the drum body (171), and the drum supply hole (152) must be provided on the rear side of the drum body (171).

[0046] When the drum body (171) is provided in a cylindrical shape with both the front and rear sides closed, the front panel (14) and the rear panel (15) may be omitted, and the rear side of the drum body (171) may be rotatably supported on the rear side (12) of the cabinet, etc., via a rotational axis. In order to discharge air inside the drum body (171) into the circulation path, the drum exhaust hole (143) may be provided on the circumferential surface of the drum body (171).

[0047] The above circulation path (2) may be provided to include a first duct (21) connected to the drum exhaust hole (143), a second duct (22) connected to the drum supply hole (152), and a third duct (23, connecting duct) connecting the first duct and the second duct. The connecting duct (23) may be provided to be fixed to the base (13).

[0048] As shown in Fig. 4, the heat exchange unit (3) may be provided to include a circulation fan (36) that moves air along the circulation path (2), and a heat pump (31, 32, 33, 34, 35) that sequentially performs dehumidification and heating of the air moving along the circulation path (2).

[0049] The above circulation fan (36) may be provided to include a fan impeller (361) located inside the circulation path (2), and a fan motor (362) located outside the circulation path (2) and rotating the fan impeller (361).

[0050] The above heat pump may be provided to include a refrigerant pipe (33) forming a path through which refrigerant circulates, a compressor (34) causing the refrigerant to move along the refrigerant pipe (33), a first heat exchanger (31) fixed to the refrigerant pipe (33) and transferring heat of air introduced into the connecting duct (23) to the refrigerant, a second heat exchanger (32) fixed to the refrigerant pipe (33) and transferring heat of the refrigerant to air passing through the first heat exchanger (31), and a control valve (35) for controlling the pressure of the refrigerant.

[0051] The above-mentioned connecting duct (23) may be provided to include a duct body (231) fixed to the base (13) and a duct cover (232) forming an upper surface of the duct body. The duct body (231) may be provided to include a first mounting portion (233) on which the first heat exchanger (31) is mounted, and a second mounting portion (234) on which the second heat exchanger (32) is mounted.

[0052] The air introduced into the above connecting duct (23) is condensed as it passes through the first heat exchanger (31), heated as it passes through the second heat exchanger (32), and moves to the drum body (171) through the second duct (22) and the drum supply hole (152).

[0053] The above circulation path (2) may be provided with a heat exchanger support member (4) that supports the bottom surface of the first heat exchanger (31). The heat exchanger support member (4) divides the inside of the connection duct (23) into a mounting space (233a) where the first heat exchanger (31) is located, and a drainage space (233b) that guides condensate to the outside of the circulation path. The drainage space (233b) is located at the lower portion of the mounting space (233a), and a drainage port (5) is provided in the drainage space (233b).

[0054] The above heat exchanger support (4) is provided with a support penetration hole (411). Therefore, condensate discharged from the air passing through the first heat exchanger (31) can move to the drainage space (233b) through the support penetration hole (411).

[0055] As shown in Fig. 3, the base (13) may be provided with a collection unit (6) in which condensate generated when air passing through the first heat exchanger (31) is condensed is stored.

[0056] The above water collecting unit (6) may be located outside the circulation path (2). In this case, the water collecting unit (6) may be connected to the drainage space (233b) through a drainage port (5) provided to pass through the connection duct (23).

[0057] The condensate stored in the above collection unit (6) can be discharged to the drain tank (8) through the drain unit (7). The drain tank (8) can be provided to be located at a higher point than the above collection unit (6).

[0058] The above drain tank (8) may be provided to include a drawer (81) that is provided to be withdrawable from the cabinet (1) and provides a space for storing condensate, and a drawer penetration hole (82) that is provided to penetrate the upper surface of the drawer (81).

[0059] An outlet (112) for the entry and exit of the drawer (81) may be provided on the front surface (11) of the cabinet, and a tank housing (16) providing a space for accommodating the drawer (81) may be provided inside the cabinet (1).

[0060] The above drainage unit (7) may be equipped with a drainage pump (71). The condensate discharged from the water collection unit (6) through the drainage pump (71) moves to the tank housing (16) through the supply pipe (72), and the condensate discharged from the supply pipe (72) may move into the interior of the drawer (81) through the drawer penetration hole (82).

[0061] Meanwhile, if too much condensate is supplied to the drawer (81), the condensate inside the drawer (81) may flow back into the tank housing (16) through the drawer penetration hole (82). Therefore, the drainage unit (7) may further be provided with a recovery pipe (73) connecting the bottom surface of the tank housing (16) and the water collecting unit (6). The condensate discharged from the drawer (81) to the tank housing (16) will move to the water collecting unit (6) through the recovery pipe (73).

[0062] As shown in Fig. 5, the clothing treatment device (100) may be equipped with a first detection unit (91) and a second detection unit (93).

[0063] The first detection unit (91) may be provided as a means for measuring the dryness through contact with clothing, and the second detection unit (93) may be provided as a means for measuring the dryness by detecting heat emitted from clothing.

[0064] The first detection unit (91) may be provided with a first electrode (911) and a second electrode (912) that are arranged to be spaced apart from each other, and a detection circuit (not shown) that connects the two electrodes. The first electrode (911) and the second electrode (912) may be provided to be fixed at points spaced apart from each other so as to be connectable by clothing. FIG. 5 illustrates an example in which the two electrodes (911, 912) are fixed to the front panel (14).

[0065] The first electrode (911) and the second electrode (912) may be fixed to the front panel body (141). In order for the two electrodes (911, 912) to be connected by clothing, it is preferable that the first electrode (911) and the second electrode (912) be fixed to a space provided by the front panel body (141) and located between the drum inlet (142) and the front support body (144).

[0066] Furthermore, in order to facilitate the clothing's contact with the two electrodes (911, 912) when the drum body (171) rotates, it is preferable that the two electrodes (911, 912) be positioned at the bottom of the drum inlet (142).

[0067] When the drum body (171) rotates, the two electrodes (911, 912) can be connected by clothing. When clothing connects the two electrodes (911, 912) while voltage is applied to the detection circuit, the resistance or impedance of the detection circuit will vary depending on the amount of water remaining in the clothing. When the amount of water remaining in the clothing is large (when the dryness level is low), the resistance of the detection circuit will be relatively small, and when the amount of water remaining in the clothing is small (when the dryness level is high), the resistance of the detection circuit will be relatively large. Therefore, the clothing treatment device (100) can determine the dryness of the clothing through the first detection unit (91).

[0068] The above second sensing unit (93) can be provided with various structures as long as it can measure the temperature of clothing without coming into contact with the clothing. FIG. 5 illustrates an example in which the second sensing unit (93) is provided with an infrared sensor that determines the temperature of clothing through infrared detection.

[0069] The above second drying unit (93) may be equipped with only a light-emitting unit that receives infrared rays, or may be equipped with a light-emitting unit that emits infrared rays to clothing and a light-receiving unit that receives infrared rays reflected from clothing.

[0070] The second detection unit (93) is preferably fixed in a space provided by the front panel body (141) between the drum inlet (142) and the front support body (144). In order to easily detect infrared rays emitted from clothing located on the rear surface of the drum body (171), the second detection unit (93) is preferably positioned above the drum inlet (142) in the space provided by the front panel body (141).

[0071] Fig. 6 illustrates an example of a control method of the above-described clothing treatment device, and the control method includes a drying step (S30) and a detection step (S40).

[0072] The above drying step (S30) may be provided as a step of removing water from clothing by supplying air to the receiving portion (17). To facilitate drying of clothing, the drying step (S30) may be provided to include a step of operating the driving portion (18) to rotate the receiving portion (17) and a step of supplying air to the receiving portion (17) through the heat exchange portion (3).

[0073] In order to set the execution time of the above drying step (S30), the control method may further include a load judgment step (S10) and an execution time setting step (S20).

[0074] The above load determination step (S10) may be provided as a step for measuring the amount of clothing stored inside the receiving portion (17), and the above execution time setting step (S20) may be provided as a step for setting the execution time according to the amount (load) of clothing stored in the receiving portion (17).

[0075] The above load determination step (S10) may be provided as a step of measuring the amount of power supplied to the drum motor (181) to rotate the receiving portion (17) to a preset reference angle, or the amount of power supplied to the drum motor (181) to increase the receiving portion (17) to a preset speed. In this case, the clothing treatment device (100) can determine the amount of clothing stored in the receiving portion (17) by comparing the amount of power measured in the load determination step (S10) with preset power data (power data by load).

[0076] The above execution time setting step (S20) can set the execution time to increase in proportion to the load, and can be a step of selecting the setting time corresponding to the load measured from data in which the execution time for each load is set.

[0077] The above detection step (S40) may be provided to include a step of determining the dryness of clothing through the first detection unit (91) (S41, resistance detection step, impedance detection step), and a step of determining the dryness of clothing through the second detection unit (93) (S43, temperature detection step).

[0078] During execution of the above drying step (S30) and the above detection step (S40), the control method can execute the first judgment step (S60) and the second judgment step (S70).

[0079] The first judgment step (S60) may be provided as a step for judging whether the dryness measured through the first detection unit has reached a preset reference dryness, and the second judgment step (S70) may be provided as a step for judging whether the dryness specified through the second detection unit has reached a preset target dryness. It is preferable that the reference dryness be set to a dryness lower than the target dryness, and the second judgment step (S70) may be initiated when the first judgment step (S60) is terminated.

[0080] As described above, the first sensing unit (91) is a means for generating a control signal based on the amount of water remaining in the clothing, and the second sensing unit (93) is a means for generating a control signal based on the amount of heat emitted from the clothing.

[0081] When the section below the standard dryness level is defined as the beginning of the drying step (S30) and the section above the standard dryness level is defined as the end of the drying step (S30), in the beginning of the drying step, the change in the amount of water remaining in the clothing is large while the change in the temperature of the clothing is small, and in the end of the drying step, the change in the amount of water remaining in the clothing is small while the change in the temperature of the clothing is large. Therefore, if the sensing step (S40) is configured with only the first sensing unit (91), there is a disadvantage that it is not easy to measure the dryness level in the end of the drying step, and if the sensing step (S40) is configured with only the second sensing unit (93), there is a disadvantage that it is not easy to measure the dryness level in the beginning of the drying step.

[0082] The control method of Fig. 6 can overcome the above-described disadvantage by determining the dryness level through the first detection unit (91) in the early stage of the drying stage and determining the dryness level through the second detection unit (93) in the later stage of the drying stage.

[0083] Experiments have shown that the point at which the temperature change of the clothing becomes rapid during the drying step (S30) is when the dryness of the clothing is between 70% and 90% of the target dryness. Therefore, it is preferable that the reference dryness be set to a value between 70% and 90% of the target dryness.

[0084] Meanwhile, the heat exchange between the air supplied from the heat exchange unit (3) and the clothing begins in earnest when the temperature inside the receiving unit (17) becomes similar to the temperature of the surroundings surrounding the receiving unit. In other words, after the drying step (S30) is initiated, there will be no significant change in the dryness of the clothing until the temperature of the surroundings surrounding the receiving unit (17) (the temperature inside the cabinet) becomes similar to the temperature inside the receiving unit (17).

[0085] Therefore, it is preferable that the first judgment step (S60) is initiated when the time for executing the drying step (S30) reaches a preset execution standard time, and the second judgment step (S70) is initiated when the first judgment step (S60) is completed.

[0086] In order to accurately determine whether the dryness of the clothing has reached the standard dryness, the first determination step (S60) may be provided so as to determine that the dryness of the clothing is higher than the standard dryness when the state of being higher than the standard dryness is maintained for a preset first duration of time.

[0087] In addition, in order to accurately determine whether the dryness of the clothing has reached the target dryness, the second determination step (S70) may be configured to determine that the dryness of the clothing has reached the target dryness when the state of reaching the target dryness is maintained for a preset second duration. Accordingly, the control method is capable of accurately detecting the dryness.

[0088] If it is determined through the second judgment step (S70) that the dryness of the clothing has reached the target dryness, the control method may execute a termination step (S80) that terminates the operation of the heat exchange unit (3). After the drying step is completed, the control method may execute a cooling step that operates the circulation fan (36) to lower the temperature of the clothing.

[0089] Meanwhile, the control method may further include a step (S71) of determining whether the time (remaining time) required to reach the execution time set in the execution time setting step (S20) is greater than or equal to the reference remaining time. This is to terminate the operation of the clothing treatment device (100) when it is difficult to determine whether the dryness has reached the target dryness due to reasons such as a breakdown of the second detection unit (93). That is, when it is determined (S71) that the remaining time is less than the reference remaining time but the dryness has not reached the target dryness, the control method may terminate the drying step (S80).

[0090] However, in order to minimize the possibility that the drying step (S30) ends with the dryness of the clothes being low, the control method may further include a step (S73) of adjusting the set time. That is, if it is determined that the dryness has not reached the target dryness until the remaining time reaches the reference remaining time, the control method may execute the set time adjusting step (S73).

[0091] The above-mentioned setting time adjustment step (S73) may be provided as a step of increasing the execution time set in the above-mentioned execution time setting step (S20) by a preset additional time. In this case, the above-mentioned drying step (S30) will be terminated (S80) when the execution time of the above-mentioned drying step reaches the adjusted setting time.

[0092] Since the above-described clothing treatment device and control method are examples of the present invention, the scope of rights of the present application cannot be limited to the above-described structure and control method.
