The washing machine 100 is a device that washes contaminated laundry. The washing machine 100 may be classified into various types according to a method of washing laundry. Examples of the washing machine 100 may include an agitation type washing machine, an impeller type washing machine, and a drum type washing machine. The washing machine 100 may also be classified according to a method of loading laundry. Examples of the washing machine 100 may include a top load type washing machine and a front load type washing machine.
The dryer 2000 is a device that dries wet laundry. The dryer 2000 may be classified into various types according to a method of drying laundry. The dryer 2000 may include, for example, a gas dryer, an electric dryer, or a ventless type dryer.
According to an embodiment of the present disclosure, the dryer 2000 may interact with the washing machine 100. The dryer 2000 interacting with the washing machine 100 may refer to the dryer 2000 using information obtained from the washing machine 100 in a drying process. Referring to
According to a disclosed embodiment, the data 110 related to the washing process refers to data obtained while the washing machine 100 is washing laundry. The washing process of the washing machine 100 may include, but is not limited to, a loading operation, a washing operation, a rinsing operation, a spin-drying operation, and a washing completion operation of laundry. The washing machine 100 may obtain the data 110 related to the washing process, through processes of washing laundry. The data 110 related to the washing process may include, for example, washing mode setting information 101 of the washing machine 100, a weight 102 of laundry before washing, a flow rate 103 of water introduced in the washing operation, a flow rate 104 of water introduced in the rinsing operation, a weight 105 of laundry after washing, and other data 106 (e.g., a washing completion time, a water temperature, and a degree of spin-drying). However, the data 110 related to the washing process is not limited thereto, and may further include other data that may be obtained during the washing process in which the washing machine 100 washes laundry. The dryer 2000 may obtain the data 110 related to the washing process from the washing machine 100, or may obtain, from the server, the data 110 related to the washing process transmitted from the washing machine 100 to the server.
According to an embodiment, the dryer 2000 may determine whether the to-be-dried laundry loaded into the dryer 2000 corresponds to the laundry washed by the washing machine 100. For example, the dryer 2000 may determine whether the to-be-dried laundry loaded into the dryer 2000 is the laundry washed by the washing machine 100, by comparing the weight of the to-be-dried laundry loaded into the dryer 2000 with the weight 105 of the laundry washed by the washing machine 100 or comparing a time point when the to-be-dried laundry has been loaded into the dryer 2000 with a washing completion time.
According to an embodiment, the dryer 2000 may utilize the data 110 related to the washing process in the drying process of the dryer 2000. When laundry loaded into the dryer 2000 is laundry loaded into the dryer 2000 from the washing machine 100, the dryer 2000 may determine a setting value of the dryer 2000 by using the data 110 related to the washing process. For example, the dryer 2000 may set a corresponding drying mode, based on the washing mode setting information 101 of the washing machine 100. For example, the dryer 2000 may determine a target dry weight of the laundry loaded into the dryer 2000 from the washing machine 100. The target dry weight may refer to a standard weight based on which the dryer 2000 may determine that drying of laundry has been completed.
According to an embodiment, the dryer 2000 may obtain the data 130 related to the drying process, while performing the drying process. The data 130 related to the drying process refers to data obtained while the dryer 2000 is drying laundry. The data 130 related to the drying process may include, for example, drying mode setting information of the dryer 2000, the weight of laundry being dried, an internal temperature of a drum, and an internal humidity of the drum. However, the data 130 related to the drying process is not limited thereto, and may further include other data that may be obtained during the drying process in which the dryer 2000 dries laundry.
While performing the drying process, the dryer 2000 may output information about the drying state of the laundry being dried, based on at least one of the weight of the laundry being dried, the internal temperature of the drum, and the internal humidity of the drum. For example, when the weight of the laundry reaches a target dry weight before the set drying time elapses, the dryer 2000 may determine that the drying of the laundry being dried is completed, and output information indicating that the drying of the laundry has been completed. For example, when the weight of the laundry does not reach the target dry weight even when the set drying time elapses, the dryer 2000 may determine that the drying of the laundry being dried is not completed, and output information indicating that drying of the laundry is further needed.
According to an embodiment of the present disclosure, when the weight of the laundry reaches the target dry weight before the set drying time elapses, the dryer 2000 may determine that the drying of the laundry being dried has been completed, and automatically terminate the drying process. When the weight of the laundry does not reach the target dry weight even when the set drying time elapses, the dryer 2000 may determine that the drying of the laundry being dried is not completed, and predict an additional drying time necessary until the weight of the laundry reaches the target dry weight. The dryer 2000 may display the predicted additional drying time.
The dryer 2000 according to one embodiment may control the drying process so that drying of the laundry loaded from the washing machine 100 into the dryer 2000 is completed at an optimal time, based on the data 110 related to the washing process and the data 130 related to the drying process. An operation, performed by the dryer 2000, of optimizing a drying process will now be described in detail with reference to
In describing embodiments, laundry loaded into the dryer 2000 and subject to drying will be referred to as first laundry, and laundry washed by the washing machine 100 will be referred to as second laundry.
In operation S210, the dryer 2000 according to an embodiment may detect the first laundry loaded into the dryer 2000 and subject to drying, by using one or more sensors built in the dryer 2000.
According to an embodiment, the dryer 2000 may identify that the first laundry has been loaded into a drum, which is a space capable of accommodating laundry in the dryer 2000, by using one or more sensors built in the dryer 2000, such as a door sensor, a proximity sensor, and a weight sensor.
In operation S220, the dryer 2000 according to an embodiment may obtain data related to a washing process with respect to the second laundry loaded into the washing machine 100 before the first laundry is loaded into the dryer 2000.
According to an embodiment, the dryer 2000 may obtain data related to the washing process of the second laundry in order to identify whether the first laundry loaded into the dryer 2000 corresponds to the second laundry washed in the washing machine 100. The first laundry corresponding to the second laundry may refer to the entirety of the first laundry being identical to the entirety or a predetermined portion or more (e.g., 70% or more) of the second laundry. For example, based on a time point when it is identified that the first laundry has been loaded into the dryer 2000, the dryer 2000 may obtain the data related to the washing process of the second laundry, which has been completely washed, from the washing machine 100 before a time point when the first laundry is loaded into the dryer 2000. The data related to the washing process of the second laundry may include, for example, at least one of the weight of the second laundry before washing, the weight of the second laundry after washing, the flow rate of water introduced in the washing process of the second laundry, the moisture content of the second laundry, and a washing mode applied to the washing process of the second laundry. The dryer 2000 may obtain the data related to the washing process of the second laundry from the washing machine 100, or may obtain the data related to the washing process of the second laundry from the server.
In operation S230, the dryer 2000 according to an embodiment may determine whether the first laundry corresponds to the second laundry, based on the data related to the washing process of the second laundry. The dryer 2000 may determine whether the first laundry loaded into the dryer 2000 corresponds to all of the second laundry washed in the washing machine 100 or the first laundry loaded into the dryer 2000 corresponds to a portion of the second laundry washed in the washing machine 100.
According to an embodiment, the dryer 2000 may identify the weight of the first laundry. For example, the dryer 2000 may rotate the drum of the dryer 2000 by controlling a motor of the dryer 2000. The dryer 2000 may measure a load applied to the drum when the drum of the dryer 2000 is rotated, and may identify the weight of the first laundry, based on the measured load. For example, the dryer 2000 may measure the weight of the first laundry loaded into the drum of the dryer 2000, by using a weight sensor built in the dryer 2000. However, a method, performed by the dryer 2000, of identifying the weight of the first laundry is not limited to the above-described example.
According to an embodiment, the dryer 2000 may compare the weight of the first laundry with the weight of the second laundry after washing. For example, when the weight of the first laundry is equal to the weight of the second laundry after washing, the dryer 2000 may determine that the first laundry is the same as the second laundry. For example, when a difference between the weight of the first laundry and the weight of the second laundry after washing is within a certain range, the dryer 2000 may determine that the first laundry is the same as the second laundry. In other words, the dryer 2000 may compare the weight of the first laundry with the weight of the second laundry after washing to determine that the second laundry that has been washed in the washing machine 100 is the first laundry loaded into the dryer 2000.
According to an embodiment, the dryer 2000 may identify a difference between a first time when the first laundry is loaded into the dryer 2000 and a second time when the second laundry is taken out from the washing machine 100. The first time and the second time refer to times set to determine whether the second laundry taken out from the washing machine 100 corresponds to the first laundry loaded into the dryer 2000. For example, the dryer 2000 may identify, as the second time, a time when the door of the washing machine 100 is opened after the washing is finished, and may identify, as the first time, a time when the door of the dryer 2000 is open. For example, the dryer 2000 may identify, as the second time, a time when the washing of the washing machine 100 is finished, and may identify, as the first time, a time when the first laundry is detected by the dryer 2000. However, definitions of the first time and the second time are not limited to the aforementioned example.
The dryer 2000 may determine whether the first laundry corresponds to the second laundry, based on the difference between the first time and the second time. When the difference between the first time and the second time is within a certain range, the dryer 2000 may determine that the first laundry is the same as the second laundry.
According to an embodiment, the dryer 2000 may determine whether the first laundry corresponds to the second laundry, based on a combination of the difference between the weight of the first laundry and the second laundry and the difference between the first time and the second time. For example, when the difference between the weight of the first laundry and the second laundry after washing is within a predetermined rang and the difference between the first time when the first laundry is loaded into the dryer 2000 and the second time when the second laundry is taken out from the washing machine 100 is within a predetermined range, the dryer 2000 may determine that the first laundry is the same as the second laundry. A method, performed by the dryer 2000 according to an embodiment, of determining whether the first laundry corresponds to the second laundry will be described later with reference to
In operation S240, when the first laundry corresponds to the second laundry, the dryer 2000 according to an embodiment may determine the weight of the second laundry before washing as a first target dry weight. Because the dryer 2000 has identified that the first laundry loaded into the dryer 2000 is the second laundry washed by the washing machine 100, the dryer 2000 may determine the weight of the second laundry before washing, which is in a not-wet state, as the first target dry weight. The dryer 2000 may use the first target dry weight as information for identifying completion of drying of the first laundry.
In operation S250, the dryer 2000 according to an embodiment may output information about the drying state of the first laundry, based on at least one of a drying time period set in the dryer 2000 and whether the weight of the first laundry reaches the first target dry weight.
The dryer 2000 according to an embodiment may identify whether the weight of the first laundry reaches the first target dry weight, by using one or more sensors. According to an embodiment, as the first laundry is dried in the dryer 2000, the water contained in the first laundry evaporates, and thus the weight of the first laundry may decrease. The dryer 2000 may identify that the weight of the first laundry decreases due to the drying and reaches the first target dry weight. The weight of the first laundry reaching the first target dry weight may refer to not only the weight of the first laundry becoming equal to the first target dry weight, but also a difference between the weight of the first laundry and the first target dry weight becoming less than or equal to a predetermined threshold value. For example, when the dryer 2000 dries the first laundry loaded into the dryer 2000, the dryer 2000 may measure a load applied to the drum when the drum of the dryer 2000 is rotated, and may identify the weight of the first laundry, based on the measured load. For example, the dryer 2000 may measure a change in the weight of the first laundry loaded into the drum of the dryer 2000, by using a weight sensor built in the dryer 2000. However, a method, performed by the dryer 2000, of identifying a change in the weight of the first laundry is not limited to the above-described example.
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry has reached the first target dry weight before the drying time period set in the dryer 2000 ends, the dryer 2000 may output information indicating that the drying of the first laundry has been completed.
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry has reached the first target dry weight before the drying time period set in the dryer 2000 ends, the dryer 2000 may identify the internal temperature and internal humidity of the drum of the dryer 2000. The dryer 2000 may output the information indicating that the drying of the first laundry has been completed, based on the weight of the first laundry and the internal temperature and internal humidity of the drum.
According to an embodiment, the second laundry in a partially wet state is loaded into the washing machine 100, so the first target dry weight determined based on the weight of the second laundry before washing may not be a completely dry state. In this case, even when the weight of the first laundry reaches the first target dry weight, the dryer 2000 may output information indicating that a drying state of the first laundry needs more drying, based on the internal temperature and internal humidity of the drum.
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry has not reached the first target dry weight even when the drying time period set in the dryer 2000 has ended, the dryer 2000 may output the information indicating that a drying state of the first laundry needs more drying.
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry loaded into the dryer 2000 has reached the first target dry weight, the dryer 2000 may conclude the drying process of the dryer 2000. The dryer 2000 may end the drying process, and may output the information indicating that the drying of the first laundry has been completed or the information indicating that a drying state of the first laundry needs more drying, which is determined according to the above-described embodiments.
Although a case where the first laundry loaded into the dryer 2000 is the same as all of the second laundry washed in the washing machine 100 has been described above as an example, the first laundry loaded into the dryer 2000 may be a remaining portion of the completely washed second laundry after a user excludes a portion from the completely washed second laundry, and the remaining portion is loaded into the dryer 2000 by the user. In this case, the dryer 2000 may determine a second target dry weight for drying the first laundry, and identify whether the weight of the first laundry reaches the second target dry weight, thereby performing the above-described operations. A method, performed by the dryer 2000 according to an embodiment, of determining the first target dry weight or the second target dry weight will be described later with reference to
The operation described with reference to
Based on a weight 324 of second laundry 320 washed in the washing machine 100 and a weight 312 of first laundry 310, the dryer 2000 according to an embodiment may determine whether the first laundry 310 corresponds to the second laundry 320.
The dryer 2000 according to an embodiment may identify the weight of the first laundry 310. The dryer 2000 may determine whether the first laundry 310 corresponds to the second laundry 320, based on the weight 324 of second laundry 320 which is included in data related to a washing process with respect to the second laundry 320 and the weight 312 of first laundry 310.
According to an embodiment, the weight of the second laundry 320 being washed in the washing machine 100 may change as the washing process is performed. For example, a weight 322 of the second laundry 320 in a dry state before washing may be less than the weight 324 of the second laundry 320 in a wet state after washing. The dryer 2000 may obtain the weight 324 of the second laundry 320 after washing from the washing machine 100. The dryer 2000 may compare the weight 324 of the second laundry 320 after washing with the weight 312 of the first laundry 310 after washing, and may determine whether the first laundry 310 corresponds to the second laundry 320, based on a result of the comparison.
According to an embodiment, when the weight 312 of the first laundry 310 is equal to the weight 324 of the second laundry 320 after washing, or when the weight 312 of the first laundry 310 is less than the weight 324 of the second laundry 320 after washing and a difference between the weight 312 of the first laundry 310 and the weight 324 of the second laundry 320 after washing is a predetermined threshold or less, the dryer 2000 may determine that the first laundry 310 corresponds to the second laundry 320. For example, the weight 322 of the second laundry 310 before washing is 4.5 kg, but the weight 324 of the second laundry 320 after washing as the washing process is performed may be 6.8 kg by including the weight of absorbed water. The dryer 2000 may obtain the weight 322 of the second laundry 320 before washing, which is 4.5 kg, and the weight 324 of the second laundry 320 after washing, which is 6.8 kg. The dryer 2000 may measure the weight 312 of the first laundry 310 and identify that the weight 312 of the first laundry 310 is 6.7 kg. A predetermined threshold for the difference between the weight 312 of the first laundry 310 and the weight 324 of the second laundry 320 after washing may be 0.5 kg. In this case, because the weight 312 of the first laundry 310 is 0.1 kg less than the weight 324 of the second laundry 320 after washing and the weight 312 of the first laundry 310 is less than the weight 324 of the second laundry 320 after washing and the difference between the weight 312 of the first laundry 310 and the weight 324 of the second laundry 320 after washing is less than the predetermined threshold of 0.5 kg, the dryer 2000 may determine that the first laundry 310 corresponds to the second laundry 320 after washing. In other words, the dryer 2000 may determine the first laundry 310 to be the second laundry 320 that has been washed in the washing machine 100.
The operation described with reference to
The dryer 2000 according to an embodiment may identify the difference between the first time when the first laundry is loaded into the dryer 2000 and the second time when the second laundry is taken out from the washing machine 100, and may determine whether the first laundry corresponds to the second laundry, based on the time information.
According to an embodiment, the dryer 2000 may compare a weight 410 of the second laundry after washing with a weight 415 of the first laundry loaded into the dryer 2000, and may determine whether the first laundry corresponds to the second laundry, based on a result of the comparison. Because this has already been described above with reference to
According to an embodiment, the first time indicating the time when the first laundry is loaded into the dryer 2000 and the second time indicating the time when the second laundry is taken out of the washing machine 100 may be set in various ways.
For example, the first time may be a door opening time 425 of the dryer 2000 before the drying process in the dryer 2000 begins, and the second time may be a door opening time 420 of the washing machine 100 after the washing process in the washing machine 100 ends. The dryer 2000 may identify a difference between the first time and the second time, and, when the difference between the first time and the second time is less than or equal to a predetermined threshold, may determine that the first laundry corresponds to the second laundry.
For example, the first time may be a drying start time of the dryer 2000 or a time when the first laundry is loaded into the dryer 2000, which is indicated by reference numeral 435, and the second time may be a washing end time of the washing machine 100 or a time when the second laundry is taken out of the washing machine 100, which is indicated by reference numeral 430. The dryer 2000 may identify the difference between the first time and the second time, and, when the difference between the first time and the second time is less than or equal to a predetermined threshold, may determine that the first laundry corresponds to the second laundry.
The dryer 2000 according to an embodiment may determine whether the first laundry corresponds to the second laundry, based on the weight information, determine whether the first laundry corresponds to the second laundry, based on the time information, or determine whether the first laundry corresponds to the second laundry, based on a combination of the weight information and the time information.
The operation described with reference to
The dryer 2000 according to an embodiment may output a notification 510 guiding a user input, in order to identify whether the first laundry loaded into the dryer 2000 corresponds to the second laundry washed in the washing machine 100.
According to an embodiment, the dryer 2000 may output the notification 510 guiding a user input, through an output interface of the dryer 2000. For example, the dryer 2000 may output “Did you put the laundry washed in the washing machine into the dryer?”. In this case, the notification 510 guiding the user input may be output as a visual signal through a display included in the output interface, or as an acoustic signal through a speaker included in the output interface.
According to an embodiment, the dryer 2000 may output the notification 510 guiding a user input, through a user's device (for example, a smartphone). For example, the dryer 2000 may enable the user's device to output a message including the notification 510 guiding a user input, through communication using a server (not shown) or direct communication with the user's device. The user's device may output the notification 510 guiding a user input, on an execution window of a predetermined application or in the form of a pop-up message on a home screen. The predetermined application may be an application that provides information related to at least one previously-registered home appliance.
The dryer 2000 according to an embodiment may identify whether the first laundry corresponds to the second laundry, based on an input received from the user. For example, when the user selects “yes” in response to the notification 510 guiding the user input, “Did you put the laundry washed in the washing machine into the dryer?”, the dryer 2000 may identify that the first laundry corresponds to the second laundry.
As described above with reference to
In operation S610, the dryer 2000 according to an embodiment may identify whether the first laundry loaded into the dryer 2000 corresponds to all of the second laundry washed in the washing machine 100. The first laundry corresponding to the entire second laundry means that all of the second laundry that has been washed in the washing machine 100 is loaded into the dryer 2000. The dryer 2000 may determine whether the first laundry corresponds to all of the second laundry, based on at least some of weight information of the first laundry and the second laundry, information of the first time when the first laundry is loaded into the dryer 2000 and the second time when the second laundry is taken out from the washing machine 100, ora user input. Because this has already been described above with reference to
According to an embodiment, when the first laundry corresponds to all of the second laundry, the dryer 2000 may perform operation S620. A case where the first laundry corresponds to a portion of the second laundry will be explained with reference to
In operation S620, when the first laundry corresponds to all of the second laundry, the dryer 2000 according to an embodiment may determine a weight 602 of the second laundry before washing as a first target dry weight 608. In other words, because all of the second laundry washed in the washing machine 100 has been loaded into the dryer 2000, the dryer 2000 may determine the weight 602 of the second laundry before washing as the first target dry weight 608, in order to terminate drying when a weight 606 of the first laundry reaches the weight 602 of the second laundry before washing. The first target dry weight 608 refers to a standard weight for determining that, when the first laundry corresponds to all of the second laundry, drying of the first laundry corresponding to all of the second laundry has been completed.
For example, the weight 602 of the second laundry before washing may be 4.5 kg, and a weight 604 of the second laundry after washing may be 6.8 kg. The weight 606 of the first laundry identified by the dryer 2000, which is 6.7 kg, may be less than or equal to 6.8 kg as the weight 604 of the second laundry after washing. In this case, when it is determined that the first laundry corresponds to all of the second laundry according to the above-described embodiments, the dryer 2000 may determine the first target dry weight 608 of the first laundry as the weight 602 of the second laundry before washing, which is 4.5 kg.
In operation S630, the dryer 2000 according to an embodiment may perform a drying process. While performing the drying process, the dryer 2000 may identify that the weight 606 of the first laundry decreases as the water contained in the first laundry evaporates. When the weight 606 of the first laundry reaches the first target dry weight 608, the dryer 2000 may end the drying process or output information indicating the drying state of the first laundry.
In the description of
In operation S710, the dryer 2000 according to an embodiment may compare the weight of the first laundry loaded into the dryer 2000 with the weight of the second laundry washed in the washing machine 100.
When, in operation S720, the weight of the first laundry is less than the weight of the second laundry after washing and a difference between the weight of the first laundry and the weight of the second laundry after washing is greater than a first threshold, as a result of the comparison in operation S710, the dryer 2000 according to an embodiment may perform operation S730.
When the weight of the first laundry is less than the weight of the second laundry after washing but the difference between the weight of the first laundry and the weight of the second laundry after washing is less than or equal to the first threshold, the dryer 2000 may determine that the first laundry corresponds to all of the second laundry, as described above with reference to
In operation S730, the dryer 2000 according to an embodiment may compare, with a second threshold, a difference between a first time when the first laundry is loaded into the dryer 2000 and a second time when the second laundry is taken out from the washing machine 100. When the difference between the first time and the second time is less than or equal to the second threshold, the dryer 2000 may perform operation S740. When the difference between the first time and the second time is greater than the second threshold, the dryer 2000 may perform operation S735 to check with the user of the dryer 2000 whether the first laundry corresponds to a portion of the second laundry.
In operation S735, the dryer 2000 may output, to the user, a confirmation request to check whether the first laundry corresponds to a portion of the second laundry.
In operation S740, when the difference between the first time and the time the second laundry is taken out from the washing machine 100 is less than or equal to the second threshold, the dryer 2000 may determine that the first laundry corresponds to a portion of the second laundry.
When it is determined that the first laundry corresponds to a portion of the second laundry, the dryer 2000 according to an embodiment may determine the second target dry weight for drying the first laundry.
Referring to
According to an embodiment, when the user of the dryer 2000 excludes a portion of the second laundry 820 to naturally dry the same without using the dryer 2000 and thus there is laundry 830 excluded by the user, the first laundry 810 loaded into the dryer 2000 may correspond to a portion of the second laundry 820. In this case, the dryer 2000 may determine whether the first laundry 810 is a portion of the second laundry 820, based on at least one of weight information, time information, and a user input, as described above with reference to
In operation S910, the dryer 2000 according to an embodiment may identify whether the first laundry loaded into the dryer 2000 corresponds to a portion of the second laundry washed in the washing machine 100. The first laundry corresponding to a portion of the second laundry refers to a portion of the second laundry washed in the washing machine 100 being excluded and a remaining portion being loaded into the dryer 2000. The dryer 2000 may determine whether the first laundry corresponds to a portion of the second laundry, based on at least some of weight information of the first laundry and the second laundry, information of the first time when the first laundry is loaded into the dryer 2000 and the second time when the second laundry is taken out from the washing machine 100, or a user input.
According to an embodiment, when the first laundry corresponds to a portion of the second laundry, the dryer 2000 may perform operation S920. A case where the first laundry corresponds to all of the second laundry has been described above, and thus a redundant description thereof will be omitted. When the first laundry does not correspond to the second laundry, there is no need to use data related to the washing process of the second laundry, and thus the dryer 2000 may perform a basic drying process set as a default value in the dryer 2000.
In operation S920, when the first laundry corresponds to a portion of the second laundry, the dryer 2000 according to an embodiment may determine a second target dry weight 909, based on a weight 902 of the second laundry before washing, a weight 904 of the second laundry after washing, and a weight 908 of the first laundry.
For example, the weight 902 of the second laundry before washing may be 4.5 kg, and the weight 904 of the second laundry after washing may be 6.8 kg. The weight 908 of the first laundry identified by the dryer 2000 may be 5 kg. In this case, when it is determined that the first laundry corresponds to a portion of the second laundry according to the above-described embodiments, the dryer 2000 may determine that a weight 906 of laundry excluded by the user from the second laundry is 1.8 kg. The dryer 2000 may determine the second target dry weight 909, which is an estimate of the weight when the first laundry, which is remaining laundry except for the laundry excluded by the user, has been dried. The dryer 2000 may determine the second target dry weight 909 to be 3.3 kg, based on the weight 902 of the second laundry before washing, the weight 904 of the second laundry after washing, and the weight 908 of the first laundry.
In operation S930, the dryer 2000 according to an embodiment may perform a drying process. While performing the drying process, the dryer 2000 may identify that the weight 908 of the first laundry decreases as the water contained in the first laundry evaporates. When the weight 908 of the first laundry reaches the first target dry weight 909, the dryer 2000 may end the drying process or output information indicating the drying state of the first laundry (for example, information indicating that it is determined that drying has been completed).
The dryer 2000 according to an embodiment may identify a change in the weight of the first laundry loaded into the dryer 2000, while performing a drying process. When the first laundry corresponds to all of the second laundry, the dryer 2000 may identify whether the weight of the first laundry reaches the first target dry weight. When the first laundry corresponds to a portion of the second laundry, the dryer 2000 may identify whether the weight of the first laundry reaches the second target dry weight. For convenience of explanation, a case where the first laundry loaded into the dryer 2000 corresponds to all of the second laundry and thus the first laundry reaches the first target dry weight will now be described as an example.
According to an embodiment, when the first laundry is loaded into the dryer 2000, the dryer 2000 may identify the weight of the first laundry, and set a drying time period of the dryer 2000, based on the identified weight. The dryer 2000 may operate to perform a drying process on the first laundry and end the drying process when the set drying time period elapses.
According to an embodiment, the dryer 2000 may output information about the drying state of the first laundry, based on at least one of the drying time period set in the dryer 2000 and whether the weight of the first laundry reaches the first target dry weight. The dryer 2000 may output information about the drying state of the first laundry through the output interface of the dryer 2000, or may output a notification guiding the user's control with respect to the dryer 2000 to a device 1000 of the user through communication using a server or direct communication with the device 1000 of the user.
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry has reached the first target dry weight before the drying time period set in the dryer 2000 ends, the dryer 2000 may output information indicating that the drying of the first laundry has been completed. When the dryer 2000 identifies that the weight of the first laundry has reached the first target dry weight before the drying time period set in the dryer 2000 ends, the dryer 2000 may identify the internal temperature and internal humidity of the drum of the dryer 2000. The dryer 2000 may output the information indicating that the drying of the first laundry has been completed, based on the weight of the first laundry and the internal temperature and internal humidity of the drum.
According to an embodiment, the dryer 2000 may terminate the drying process when it is determined that the weight of the first laundry has reached the first target dry weight and drying of the first laundry has been completed, and may output a notification indicating that the drying process has ended early (for example, “Drying has ended earlier than the set drying time period.”). In this case, the user may control the dryer 2000 by using the device 1000 of the user so that an additional drying process is performed even when the drying process of the dryer 2000 has ended.
Alternatively, the dryer 2000 may output a notification “We suggest ending drying earlier than the set drying time period” to guide the user's control with respect to the dryer 2000 to end the drying process. In this case, the user may control the dryer 2000 to stop the drying process of the dryer 2000, based on the drying state information of the first laundry provided by the dryer 2000.
According to an embodiment, the second laundry in a partially wet state is loaded into the washing machine 100, so the first target dry weight determined based on the weight of the second laundry before washing may not be a completely dry state. In this case, even when the weight of the first laundry reaches the first target dry weight, the dryer 2000 may output information indicating that a drying state of the first laundry needs more drying, based on the internal temperature and internal humidity of the drum. In this case, the user may control the dryer 2000 to perform the drying process further more than the set dry time period, based on the drying state information of the first laundry provided by the dryer 2000.
According to an embodiment of the present disclosure, the device 1000 of the user may transmit a signal for controlling the dryer 2000 to the dryer 2000 according to a user input. The device 1000 of the user may directly transmit the signal for controlling the dryer 2000 to the dryer 2000 or may transmit the signal for controlling the dryer 2000 to the dryer 2000 through a server, by short-distance wireless communication (e.g., Bluetooth, BLE, Wi-Fi Direct, etc.).
According to an embodiment, when the dryer 2000 identifies that the weight of the first laundry has not reached the first target dry weight even when the drying time period set in the dryer 2000 has ended, the dryer 2000 may output a notification “We suggest performing more drying than the set drying time period” to indicate that the drying state of the first laundry needs more drying. In this case, the user may control the dryer 2000 to perform the drying process further more even when the drying process of the dryer 2000 has ended, based on the drying state information of the first laundry provided by the dryer 2000.
According to an embodiment, when the first laundry loaded into the dryer 2000 is bulky laundry, such as a blanket, and the drying process is performed, only an outer portion of the first laundry may be dried, and an inner portion thereof may be dried relatively less. In this case, even when the drying time period set in the dryer 2000 has been reached, the weight of the first laundry may not reach the first target dry weight, and the weight of the first laundry may be heavier than the first target dry weight. At this time, the dryer 2000 may output a notification (e.g., “Please, pause drying and turn the laundry over before drying.”) guiding the user's further actions with respect to the first laundry in the dryer 2000. In this case, the user may control the dryer 2000 to resume the drying process after pausing the drying process, based on the drying state information of the first laundry provided by the dryer 2000, taking out and turning over the first laundry, and then re-loading the first laundry into the dryer 2000. Accordingly, the dryer 2000 may guide the user's control so that, while the entire portion of the first laundry is being dried uniformly, the drying process may be performed until the first target dry weight is reached.
Operations S1210 through S1230 may be performed when the dryer 2000 according to an embodiment determines that the first laundry corresponds to the second laundry.
In operation S1210, the dryer 2000 according to an embodiment may obtain the data related to the washing process of the second laundry, and determine the fabric characteristics of the second laundry. The fabric characteristics of laundry refer to the characteristics of fabric related to the washing process, such as how much water the laundry absorbs during the washing process and how fast the laundry absorbs water, and the dryer 2000 may set setting values (e.g., a temperature, a humidity, a drying time period, etc.) for drying of the dryer 2000, based on the fabric characteristics of the laundry.
The data related to the washing process of the second laundry may include, for example, at least one of the weight of the second laundry before washing, the weight of the second laundry after washing, the flow rate of water introduced in the washing process of the second laundry, the moisture content of the second laundry, and a washing mode applied to the washing process of the second laundry. The dryer 2000 may obtain the data related to the washing process of the second laundry from the washing machine 100, or may obtain the data related to the washing process of the second laundry from the server. A method, performed by the dryer 2000 according to an embodiment, of determining fabric characteristic information of the second laundry will be described later with reference to
In operation S1220, the dryer 2000 according to an embodiment may determine setting values of the dryer 2000 for drying the first laundry, based on the fabric characteristics of the second laundry. When the first laundry corresponds to the second laundry, the dryer 2000 may determine the setting values of the dryer 2000 by using the fabric characteristics of the second laundry. The dryer 2000 may determine setting values of the dryer 2000 that include at least one of a drying temperature, a drying time period, a drying humidity, and a drying mode (a standard course, a wool course, etc.), based on the fabric characteristics of the second laundry.
In operation S1230, the dryer 2000 according to an embodiment may output the determined setting values of the dryer 2000. The dryer 2000 may output the setting values of the dryer 2000 that include at least one of the drying temperature, the drying time period, the drying humidity, and the drying mode (a standard course, a wool course, etc.). The dryer 2000 may apply the setting values of the dryer 2000 for drying the first laundry, and may perform a drying process with respect to the first laundry. Alternatively, the dryer 2000 may receive a user input of adjusting or confirming the output setting values, and perform a drying process with respect to the first laundry by applying the adjusted or confirmed setting values.
The dryer 2000 according to an embodiment may obtain information related to the washing process when the washing machine 100 performs the washing process. According to an embodiment, the washing process of the washing machine 100 may include a loading operation, a washing operation, a rinsing operation, a spin-drying operation, and a washing completion operation of the second laundry. The washing machine 100 may obtain the data related to the washing process, through processes of washing the second laundry. The data related to the washing process may include, for example, washing mode setting information 1310 of the washing machine 100, a weight 1320 of the second laundry before washing, a flow rate of water introduced in the washing operation, a flow rate of water introduced in the rinsing operation, a weight 1330 of the second laundry after washing, and other data (e.g., a washing completion time, a water temperature, and a degree of spin-drying). The dryer 2000 may obtain the data related to the washing process from the washing machine 100, or may obtain from the server the data related to the washing process transmitted by the washing machine 100 to the server.
The dryer 2000 according to an embodiment may calculate the moisture content of the second laundry washed in the washing machine 100, based on the weight 1320 of the second laundry before washing and the weight 1330 of the second laundry after washing. In this case, the moisture content may be defined as Equation 1 below.
The dryer 2000 according to an embodiment may calculate the moisture content of the second laundry, based on the weight 1320 of the second laundry before washing and the weight 1330 of the second laundry after washing, and may determine the fabric characteristics of the second laundry, based on the washing mode setting information 1310 set in the washing machine 100 and the moisture content of the second laundry.
When the first laundry loaded into the dryer 2000 corresponds to the second laundry, the dryer 2000 may determine the fabric characteristics of the second laundry washed in the washing machine 100, and may use the fabric characteristics of the second laundry to perform a drying process.
An operation, performed by the dryer 2000 according to an embodiment, of determining the material of laundry, which is an example of the fabric characteristics of the laundry, will be described referring to
The dryer 2000 according to an embodiment may determine a material 1440 of the laundry, based on a washing mode 1410, a washing option 1420, and a moisture content 1430 set in the washing machine 100. The washing mode 1410 may include, for example, a standard washing mode, a quick washing mode, and a bedding washing mode, but embodiments are not limited thereto. The washing options 1420 may include, for example, a water temperature, a rinsing level, and a spin-drying level, but embodiments are not limited thereto.
The dryer 2000 according to an embodiment may determine the material 1440 of the laundry, based on a first mapping table that is previously defined. The first mapping table may be a table that maps the materials of laundry, based on the washing mode 1410, the washing option 1420, and the moisture content 1430.
According to an embodiment, when the washing mode 1410 is ‘standard’, the washing option 1420 is ‘water temperature: 70° C., rinsing level: medium, spin-drying level: strong’, and the moisture content 1430 is ‘less than 0.3’, the dryer 2000 may determine the material of the laundry to be ‘hemp’, based on the first mapping table.
According to an embodiment, when the washing mode 1410 is ‘standard’, the washing option 1420 is ‘water temperature: 70° C., rinsing level: medium, spin-drying level: strong’, and the moisture content 1430 is ‘no less than 0.5 to less than 0.7’, the dryer 2000 may determine the material of the laundry to be ‘cotton’, based on the first mapping table.

The first mapping table shown in
When it is determined that the first laundry loaded into the dryer 2000 corresponds to the second laundry washed in the washing machine 100, the dryer 2000 according to an embodiment may set a setting value of the dryer 2000, based on the fabric characteristics of the second laundry.
The dryer 2000 according to an embodiment may obtain information related to the washing process when the washing machine 100 performs the washing process. According to an embodiment, the washing process of the washing machine 100 may include a loading operation, a washing operation, a rinsing operation, a spin-drying operation, and a washing completion operation of the second laundry. The washing machine 100 may obtain the data related to the washing process, through processes of washing the second laundry. The data related to the washing process may include, for example, washing mode setting information 1510 of the washing machine 100, a weight of the second laundry before washing, a flow rate 1520 of water introduced in the washing operation, a flow rate 1530 of water introduced in the rinsing operation, a weight of the second laundry after washing, and other data (e.g., a washing completion time, a water temperature, and a degree of spin-drying). The dryer 2000 may obtain the data related to the washing process from the washing machine 100, or may obtain from the server the data related to the washing process transmitted by the washing machine 100 to the server.
The dryer 2000 according to an embodiment may calculate the water absorption rate of the second laundry, based on the flow rate 1520 of water introduced in the washing operation and the flow rate 1530 of water introduced in the rinsing operation, and may determine the fabric characteristics of the second laundry, based on the washing mode setting information 1510 set in the washing machine 100 and the water absorption rate of the second laundry.
When the first laundry loaded into the dryer 2000 corresponds to the second laundry, the dryer 2000 may determine the fabric characteristics of the second laundry washed in the washing machine 100, and may use the fabric characteristics of the second laundry to perform a drying process.
An operation, performed by the dryer 2000 according to an embodiment, of determining the material of laundry, which is an example of the fabric characteristics of the laundry, will be described referring to
The dryer 2000 according to an embodiment may determine a material 1650 of the laundry, based on a washing mode 1610, a washing option 1620, a water absorption rate 1630 in a washing operation, and a water absorption rate 1640 in a rinsing operation set in the washing machine 100.
The washing machine 100 may monitor the flow rate of water continuously introduced into the drum within the washing machine for each washing operation and each washing time, by using a water level sensor built in the washing machine 100. For example, referring to a graph 1600 showing an introduction flow rate for each washing operation and each washing time, when flow rate introduction is set to be 100 in an entire section consisting of a washing section, a rinsing section, and a spin-drying section, flow rate introduction in the washing section may be 70, flow rate introduction in the rinsing section may be 30, and flow rate introduction in the spin-drying section may be 0. The dryer 2000 may obtain data about a monitored introduction flow rate from the washing machine 100.
According to an embodiment, the dryer 2000 may calculate a water absorption rate 1630 in the washing operation, based on the washing mode 1610, the washing option 1620, and a flow rate of water introduced in the washing operation. The dryer 2000 may calculate a water absorption rate 1640 in the rinsing operation, based on the washing mode 1610, the washing option 1620, and a flow rate of water introduced in the rinsing operation.
According to an embodiment, when the user of the washing machine 100 washes the second laundry, the flow rate of water introduced in the washing operation or the flow rate of water introduced in the rinsing operation may be different even for the same second laundry, according to the degree of contamination of the second laundry or settings made by the user (e.g., additional washing, additional rinsing, etc.). The dryer 2000 may calculate a water absorption rate 1630 in the washing operation with respect to the second laundry, based on at least some of the washing mode 1610, the washing option 1620, and the flow rate of water introduced in the washing operation. For example, the dryer 2000 may normalize the flow rate of water introduced for each time of the washing section, based on the total time period of the washing section. The dryer 2000 may quantify the water absorption rate 1630 in the washing operation with respect to the second laundry, based on the flow rate of water introduced for each time in the washing section. For example, the dryer 2000 may normalize the flow rate of water introduced for each time of the rinsing section, based on the total time period of the rinsing section. The dryer 2000 may quantify the water absorption rate 1640 in the rinsing operation with respect to the second laundry, based on the flow rate of water introduced for each time in the rinsing section. The dryer 2000 calculating a water absorption rate by normalizing the flow rates of water introduced in the washing operation and the rinsing operation is only an example. The dryer 2000 may calculate the water absorption rate by using various methods capable of quantifying the water absorption rate of the second laundry, based on the flow rates of water introduced in the washing operation and the rinsing operation.
The dryer 2000 according to an embodiment may determine the material 1650 of the laundry, based on a second mapping table that is previously defined. The second mapping table may be a table that maps the materials of the laundry, based on the washing mode 1610, the washing option 1620, the water absorption rate 1630 in the washing operation, and the water absorption rate 1640 in the rinsing operation.
According to an embodiment, when the washing mode 1610 is ‘standard’, the washing option 1620 is ‘water temperature: 70° C., rinsing level: medium, spin-drying level: strong’, the water absorption rate 1630 in the washing operation is ‘30’, and the water absorption rate 1640 in the rinsing operation is ‘20’, the dryer 2000 may determine the material of the laundry to be ‘cotton’, based on the second mapping table.
According to an embodiment, when the washing mode 1610 is ‘standard’, the washing option 1620 is ‘water temperature: 70° C., rinsing level: medium, spin-drying level: strong’, the water absorption rate 1630 in the washing operation is ‘10’, and the water absorption rate 1640 in the rinsing operation is ‘5’, the dryer 2000 may determine the material of the laundry to be ‘hemp’, based on the second mapping table.
According to an embodiment, when the washing mode 1610 is ‘standard’, the washing option 1620 is ‘water temperature: 70° C., rinsing level: medium, spin-drying level: strong’, the water absorption rate 1630 in the washing operation is ‘10’, and the water absorption rate 1640 in the rinsing operation is ‘30’, the dryer 2000 may determine the material of the laundry to be ‘winter clothes (padding jumper)’, based on the second mapping table.
The second mapping table shown in
When it is determined that the first laundry loaded into the dryer 2000 corresponds to the second laundry washed in the washing machine 100, the dryer 2000 according to an embodiment may set a setting value of the dryer 2000, based on the fabric characteristics of the second laundry.
The dryer 2000 according to an embodiment may identify the fabric characteristics of laundry by using an AI model. The AI model may be a neural network model trained to infer the fabric characteristics of laundry by receiving data related to the washing process.
