- the drying time may vary depending on the drying course. For example, "very" of the bed sheets course may have a drying time longer than "very" of the wool course.
- the disclosure is not limited thereto, and the plurality of drying courses may be changed or added.
- some of the plurality of drying courses may provide a single drying level.
- the drying level may also be implemented by other methods such as "high, middle, low".

In other words, in a case of the predetermined first drying course, the processor 120 may necessarily change the drying temperature.
- the processor 120 may necessarily increase the drying temperature, in addition to the operation of changing at least one of the drying time or the drying end determination condition.
- the processor 120 may change at least only one of the drying time or the drying end determination condition. It is because the wool may have a problem of shrinkage, when the temperature is increased, whereas the shrinkage problem of the bed sheets is not significant, even when the temperature is increased.
- the processor 120 may provide a message for rechecking the drying level to the user.
- the processor 120 may provide a message for rechecking the drying level to the user. This is to identify the user's intent for the additional drying command, since the initial drying command was a command requesting for a state where the material to be dried contains moisture to some extent. In other words, in order to check whether the user changed his/her mind and wants to dry the material to be dried to have no moisture, or whether the user wants the material to be dried to contain moisture to some extent but to be dried more than the current state, the processor 120 may provide the message for rechecking the drying level to the user.
- "normal" e.g., less, damp

Abstract
Disclosed is a drying device comprising a drying unit and a processor for controlling the operation of the drying unit. The processor can control the drying unit so as to: identify, if a drying request is received, whether the drying request is an initial drying request for an object to be dried or an additional drying request for the object to be dried; and, if the drying request is identified as an additional drying request, perform an additional drying operation for the object to be dried on the basis of a drying operation method corresponding to a previous drying request for the object to be dried.
Description
- The disclosure relates to a drying apparatus and a method for controlling the same, and more particularly, relates to a drying apparatus for drying a material to be dried and a method for controlling the same.
- In recent years, with distribution of drying apparatuses, drying apparatuses providing various functions are being developed. For example, a drying apparatus provides various courses such as standard drying, rapid drying, shirt drying, time drying, AI-customized drying, delicate clothes drying, wool drying, bed sheets drying, towel drying, wind drying, and the like. In addition, the drying apparatus may provide a current operation state of the drying apparatus or request for maintenance to a user after inspecting the state of the drying apparatus.
- Although the drying apparatus provides various functions as described above, if a user selects a wrong course or dries a material to be dried such as the bed sheets, the drying to the extent desired by the user may not be performed.
- In this case, the user performs the drying again, but the drying apparatus performs the same drying operation without reflecting the previous drying history, which leads to a problem that the material to be dried is damaged due to excessive drying.
- The user may change the drying setting directly, but the user may not objectively determine a humidity state of the material to be dried that is dried primarily and it is difficult to set the drying operation not to damage the material to be dried.
- Therefore, it is necessary to develop a method for performing an optimal drying operation without user's inconvenience when performing an additional drying operation.

FIG. 1 is a block diagram illustrating a configuration of adrying apparatus 100 according to an embodiment. - The
drying apparatus 100 may be an apparatus for removing moisture of a material to be dried. For example, thedrying apparatus 100 may evaporate moisture of the material to be dried using heat or wind. In this case, thedrying apparatus 100 may evaporate moisture of the material to be dried y generating heat or wind by gas or electrical power. Particularly, thedrying apparatus 100 may include a fan and evaporate moisture by generating hot air by the fan. - In addition, the
drying apparatus 100 may separate the moisture mechanically. For example, thedrying apparatus 100 may remove moisture centrifugally by high-speed rotation. In addition, thedrying apparatus 100 may be implemented to use the method described above complexly and may be any apparatus, as long as it is an apparatus for removing moisture. - Referring to
FIG. 1 , thedrying apparatus 100 may include adrying unit 110 and aprocessor 120. - The
drying unit 110 may be a constituent element for removing moisture. For example, thedrying unit 110 may be implemented as a fan for generating wind. In addition, thedrying unit 110 may be an apparatus for generating heat. In this case, thedrying unit 110 may include a fan and generate hot air. In addition, thedrying unit 110 may be implemented to be able to perform high-speed rotation. In this case, thedrying unit 110 may include a space to which a material to be dried is input. - Hereinafter, for convenience of description, it is described that the drying
unit 110 dries the material to be dried with hot air. However, the disclosure is not limited thereto, and in a case where thedrying unit 110 uses wind or performs high-speed rotation, the embodiment may be implemented without a part related to a temperature in the following description. - The
processor 120 may generally control the operation of thedrying apparatus 100. Specifically, theprocessor 120 may be connected to each constituent element of thedrying apparatus 100 to generally control the operation of thedrying apparatus 100. For example, theprocessor 120 may be connected to the constituent elements such as the dryingunit 110, a memory (not illustrated), a display (not illustrated), a communication interface (not illustrated), and the like to control the operations of thedrying apparatus 100. - According to an embodiment, the
processor 120 may be implemented as a digital signal processor (DSP), a microprocessor, or a time controller (TCON). However, there is no limitation thereto, and theprocessor 120 may include one or more of a central processing unit (CPU), a microcontroller unit (MCU), a microprocessing unit (MPU), a controller, an application processor (AP), or a communication processor (CP), and an ARM processor or may be defined as the corresponding term. In addition, theprocessor 120 may be implemented as System on Chip (SoC) or large scale integration (LSI) including the processing algorithm or may be implemented in form of a field programmable gate array (FPGA). - When a drying command is received, the
processor 120 may identify whether the drying command is an initial drying command for a material to be dried (for ease of explanation referred to as a first material to be dried) or an additional drying command for the first material to be dried. - For example, the drying
apparatus 100 may further include a memory storing weight information on a second material to be dried immediately before receiving the drying command and humidity information on the second material to be dried. Theprocessor 120 may identify at least one of the weight information or the humidity information on the first material to be dried, and identify whether the drying command is the initial drying command or the additional drying command based on the identified information and the information stored in the memory. When a difference between the weight of the first material to be dried and the weight of the second material to be dried is within a first threshold value, theprocessor 120 may identify that the first material to be dried is the same as the second material to be dried and identify that the drying command is the additional drying command. In addition, when a difference between the humidity of the first material to be dried and the humidity of the second material to be dried is within a second threshold value, theprocessor 120 may identify that the first material to be dried is the same as the second material to be dried and identify that the drying command is the additional drying command. Further, theprocessor 120 may identify that the drying command is the initial drying command or the additional drying command by comparing all of weights and humidity of the first material to be dried and the second material to be dried. - The memory may further store opening and closing information on a door after the drying operation immediately before receiving the drying command, and the
processor 120 may identify whether the drying command is the initial drying command or the additional drying command by further considering the opening and closing information on the door. For example, although the weight difference between the first material to be dried and the second material to be dried is within the first threshold value and the humidity difference between the first material to be dried and the second material to be dried is within the second threshold value, if a difference between the opening and closing time of the door after the drying operation of the second material to be dried and the opening and closing time of the door before inputting the first material to be dried exceeds threshold time, theprocessor 120 may identify that the first material to be dried is different from the second material to be dried. - However, there is no limitation thereto, and the
drying apparatus 100 may include a plurality of buttons for each of the initial drying command and the additional drying command. In this case, a user may manipulate a button corresponding to the additional drying command and thedrying apparatus 100 may perform an additional drying operation for the first material to be dried according to the additional drying command. - When the drying command is the additional drying command, the
processor 120 may control thedrying unit 110 to perform the additional drying operation for the first material to be dried based on a drying operation method corresponding to a previous drying command for the first material to be dried. In other words, when it is identified to perform the additional drying operation for the first material to be dried, theprocessor 120 may perform the additional drying operation by changing an option of the previous drying operation method for the first material to be dried. - When the drying command is the additional drying command and a drying level of the drying operation method is a threshold level or higher, the
processor 120 may control thedrying unit 110 to perform the additional drying operation based on the drying operation method. Here, the drying level may represent one of a plurality of drying times by a drying course and the drying course may be classified based on at least one of a type or a drying method of a material to be dried. - For example, the drying
apparatus 100 may provide a plurality of drying courses such as standard drying, rapid drying, shirt drying, time drying, AI-customized drying, delicate clothes drying, wool drying, bed sheets drying, towel drying, wind drying, and the like. Each of the plurality of drying courses may provide a plurality of drying levels. For example, the shirt course may provide a plurality of drying levels such as very, more, normal, less, and damp. The drying time may be reduced in sequence from "very" to "damp". In addition, although it is at the same drying level, the drying time may vary depending on the drying course. For example, "very" of the bed sheets course may have a drying time longer than "very" of the wool course. - However, the disclosure is not limited thereto, and the plurality of drying courses may be changed or added. In addition, some of the plurality of drying courses may provide a single drying level. In addition, the drying level may also be implemented by other methods such as "high, middle, low".
- In the above example, when the drying command is the additional drying command and the drying level of the drying operation method corresponding to the previous drying command is "normal" or higher (e.g., very, more, normal), the
processor 120 may control thedrying unit 110 to perform the additional drying operation based on the drying operation method. - For example, when the drying command is the additional drying command, the
processor 120 may control thedrying unit 110 to perform the additional drying operation for the first material to be dried by changing at least one of a drying temperature, a drying time, or a drying end determination condition of the drying operation method corresponding to the previous drying command. - In addition, when the drying operation method corresponding to the previous drying command is a predetermined first drying course among the plurality of drying courses, the
processor 120 may change at least one of the drying time or the drying end determination condition, and the drying temperature, and when the drying operation method corresponding to the previous drying command is a second drying course which is the remaining course of the plurality of drying courses, theprocessor 120 may change at least one of the drying time or the drying end determination condition. In other words, in a case of the predetermined first drying course, theprocessor 120 may necessarily change the drying temperature. - For example, when the drying operation method corresponding to the previous drying command is the bed sheets course, the
processor 120 may necessarily increase the drying temperature, in addition to the operation of changing at least one of the drying time or the drying end determination condition. In addition, when the drying operation method corresponding to the previous drying command is the wool course, theprocessor 120 may change at least only one of the drying time or the drying end determination condition. It is because the wool may have a problem of shrinkage, when the temperature is increased, whereas the shrinkage problem of the bed sheets is not significant, even when the temperature is increased. - Meanwhile, when the drying command is the additional drying command and the drying level of the drying operation method is less than the threshold level, the
processor 120 may provide a message for rechecking the drying level to the user. - In the above example, when the drying command is the additional drying command and the drying level of the drying operation method corresponding to the previous drying command is lower than "normal" (e.g., less, damp), the
processor 120 may provide a message for rechecking the drying level to the user. This is to identify the user's intent for the additional drying command, since the initial drying command was a command requesting for a state where the material to be dried contains moisture to some extent. In other words, in order to check whether the user changed his/her mind and wants to dry the material to be dried to have no moisture, or whether the user wants the material to be dried to contain moisture to some extent but to be dried more than the current state, theprocessor 120 may provide the message for rechecking the drying level to the user. - When the drying level is input from the user, the
processor 120 may control thedrying unit 110 to perform the additional drying operation based on the drying operation method and the input drying level. In other words, when it is identified to perform the additional drying operation for the first material to be dried, theprocessor 120 may determine the drying level based on the information input from the user, while performing the additional drying operation by changing the option of the previous drying operation method of the first material to be dried. - When the drying command is the additional drying command and the drying level of the drying operation method corresponding to the drying command is lower than the threshold level, the
processor 120 may control thedrying unit 110 to perform the additional drying operation for the first material to be dried, by changing at least one of the drying method, the drying end determination condition, or the drying time corresponding to the input drying level of the drying operation method. - In addition, when the drying operation method corresponding to the previous drying command is the predetermined first drying course of the plurality of drying courses, the
processor 120 may change at least one of the drying end determination condition or the drying time corresponding to the input drying level, and the drying temperature, and when the drying operation method corresponding to the previous drying command is the second drying course which is the remaining course of the plurality of drying courses, theprocessor 120 may change at least one of the drying end determination condition or the drying time corresponding to the input drying level. - In other words, the
processor 120 may change the drying temperature based on the drying course of the drying operation method corresponding to the previous drying command. In addition, theprocessor 120 may perform the additional drying operation by changing one of the drying time corresponding to the previous drying level or the drying time corresponding to a drying level newly input from the user, based on the drying level of the drying operation method corresponding to the previous drying command. - Meanwhile, when the drying command is the additional drying command, the
processor 120 may identify the number of times that the additional drying command is input, and when the number of times that the additional drying command is input is two or more, theprocessor 120 may control thedrying unit 110 to perform the additional drying operation for the first material to be dried based on the drying operation method corresponding to the initial drying command and a drying operation method corresponding to at least one additional drying command before the drying command. In other words, when the additional drying command is input two or more times, theprocessor 120 may perform the additional drying operation by considering all previous drying operation methods. - However, the disclosure is not limited thereto, and when the additional drying command is input two or more times, the
processor 120 may perform the additional drying operation by considering only the latest drying operation method. -

For example, the dryingapparatus 100 may include a space for accommodating the material to be dried in a form of a drying basket or a drying drum. - However, the disclosure is not limited thereto, and the spaces for accommodating the
drying apparatus 100 and the material to be dried may be separated. In this case, a separate apparatus including a space for accommodating the material to be dried is provided, and thedrying apparatus 100 may be disposed in adjacent to the separate apparatus and perform the drying operation by supplying hot air to the space where the material to be dried is accommodated. - As described above, when the additional drying command is input, the drying
apparatus 100 performs the additional drying operation based on the previous drying operation method, which makes it possible to perform efficient drying while preventing damage on the material to be dried. - Hereinafter, the operation of the
drying apparatus 100 will be described in more detail with reference toFIGS. 3 to 8 . For convenience of description, individual embodiments will be described with reference toFIGS. 3 to 8 . However, the individual embodiments ofFIGS. 3 to 8 may be practice in a combined state. -
FIG. 3 is a flowchart illustrating an additional drying operation according to an embodiment. - First, the
processor 120 may start the drying operation (S310). For example, when a drying command is received from the user, theprocessor 120 may start the drying operation according to the received drying command. Herein, the drying operation may be the initial drying operation and the additional drying operation. - Then, the drying operation ends (S320) and the
processor 120 may identify whether it is necessary to perform the additional drying (S330). For example, theprocessor 120 may receive the additional drying command from the user. In addition, theprocessor 120 may receive the drying command from the user, identify whether a material to be dried that is currently input is a target of the drying operation within the threshold time, and identify whether to perform the additional drying. Further, after the drying operation ends, theprocessor 120 may detect a humidity of the material to be dried, and when the detected humidity is a threshold humidity or more, theprocessor 120 may provide a message suggesting the additional drying to the user. Hereinafter, for convenience of description, it is described that the user inputs the additional drying command. - When it is identified that it is not necessary to perform the additional drying, the
processor 120 may end the drying operation, and when it is identified that it is necessary to perform the additional drying and the material to be dried is input to the drying apparatus 100 (S340), theprocessor 120 may identify whether it is the same material to be dried (S350). - For example, when the drying operation ends, the
processor 120 may detect at least one of the weight or the humidity of the material to be dried, and store the detected information in thememory 130. In addition, when the additional drying command is received from the user and the material to be dried is input to thedrying apparatus 100, theprocessor 120 may detect at least one of the weight or the humidity of the input material to be dried. Theprocessor 120 may identify whether the input material to be dried is the same as the previous material to be dried by comparing results of two times of detection. - When it is identified as the same material to be dried, the
processor 120 may identify that the drying level of the previous drying is the threshold level or higher (S360). When the drying level of the previous drying is lower than the threshold level, theprocessor 120 may recheck the drying level to the user (S370). Then, theprocessor 120 may change the drying option based on the drying level input from the user (S390). - In addition, when the drying level of the previous drying is the threshold level or higher, the
processor 120 may identify the drying option to be changed by using previous course information. For example, theprocessor 120 may change the drying temperature based on whether the previous course information is a drying course delicate to the temperature. In a case of fabric such as wool, the fabric may shrink during the high-temperature drying, and accordingly, theprocessor 120 may maintain the drying temperature in a case of wool course. In contrast, when the previous course information is a drying course of bed sheets or towels that are not delicate to the temperature, theprocessor 120 may increase the drying temperature for complete drying. - In addition, when the previous course information is the drying course in which the drying level is able to be set, the
processor 120 may change the drying time based on the drying level. - In addition, in a case of a drying course in which the end of drying is determined based on moisture separately from the time, such as AI drying, the
processor 120 may change the drying end determination condition. For example, the dryingapparatus 100 may include at least one sensor which detects moisture of the material to be dried, and theprocessor 120 may determine whether to end the drying based on the number of times that the at least one sensor detects the moisture during a certain time period. - In the most drying courses, the drying operation may end based on one of the drying time and the drying end determination condition. In other words, the
processor 120 may change one of the drying time and the drying end determination condition. However, the disclosure is not limited thereto, and theprocessor 120 may end the drying operation at an earlier stage of an elapse of the drying time or satisfaction of the drying end determination condition. - In addition, even when the drying operation ends based on the drying time in the previous drying operation, the
processor 120 may end the drying operation based on the drying end determination condition in the additional drying operation. - The
processor 120 may change the drying option (S390) and perform the additional drying operation based on the changed drying option (S310). For example, in a case of changing the drying temperature, theprocessor 120 may change the drying temperature to a highest temperature. In a case where, when the temperature of the hot air is 39 degrees, the dryingunit 110 is turned on, and when the temperature of the hot air is 45 degrees, the dryingunit 110 is turned off during the previous drying operation, theprocessor 120 may turn on thedrying unit 110, when the temperature of the hot air is 45 degrees during the additional drying operation, and turn off thedrying unit 110, when the temperature of the hot air is 52 degrees. In other words, theprocessor 120 may perform the drying more reliably by increasing the temperature of the hot air operated by the dryingunit 110. - In addition, the
processor 120 may change the drying time and in this case, the change the drying time based on the drying level of the previous drying operation or the drying level input from the user. For example, when the drying time is changed based on the drying level of the previous drying operation, theprocessor 120 may perform the additional drying operation during a drying time obtained by reducing the drying time corresponding to the drying level of the previous drying operation at a threshold ratio. In addition, in a case of changing the drying time based on the drying level input from the user, theprocessor 120 may perform the additional drying operation during the drying time obtained by reducing the drying time corresponding to the drying level input from the user at a threshold ratio. - Further, the
processor 120 may change the drying end determination condition by reinforcing it even more. For example, the dryingapparatus 100 includes at least one sensor which detects the moisture of the material to be dried. If a case where the number of times that the at least one sensor detects the moisture for one minute during the previous drying operation is recorded as less than three times and this is continued two times is assumed as the drying end determination condition, theprocessor 120 may use a case where the number of times that the at least one sensor detects the moisture for one minute during the additional drying operation is recorded as less than three times and this is continued three times as the drying end determination condition. In addition, theprocessor 120 may also use a case where the number of times that the at least one sensor detects the moisture for one minute during the additional drying operation is recorded as less than two times and this is continued two times as the drying end determination condition. - In
FIG. 3 , it is described that the additional drying operation is performed in a case of the same material to be dried, but there is no limitation thereto. For example, when the additional drying command is received from the user, theprocessor 120 may perform the additional drying operation regardless whether it is the same material to be dried. In this case, theprocessor 120 may perform the additional drying operation for the material to be dried based on the drying operation method corresponding to the previous drying command. -
FIG. 4 is a diagram illustrating drying courses and drying levels according to an embodiment. - Referring to
FIG. 4 , the dryingapparatus 100 may provide a plurality of drying courses. InFIG. 4 , for convenience of description, only the bed sheets course and the wool course are illustrated, but thedrying apparatus 100 may provide various courses such as standard drying, rapid drying, shirt drying, time drying, AI-customized drying, delicate clothes drying, towel drying, wind drying, and the like. - In the bed sheets course, when the temperature of the hot air is 45 degrees, the drying
unit 110 may be turned on, and when the temperature of the hot air is 52 degrees, the dryingunit 110 may be turned off. In the wool course, when the temperature of the hot air is 39 degrees, the dryingunit 110 may be turned on, and when the temperature of the hot air is 45 degrees, the dryingunit 110 may be turned off. - However, there is no limitation thereto, and the temperatures of each course at which the
drying unit 110 is turned on and off may be variously set. - In addition, in
FIG. 4 , for convenience of description, it is illustrated that each course is divided by the temperatures at which thedrying unit 110 is turned on and off. However, there is no limitation thereto, and if a drying drum is provided, each course may also have different rotation speeds of the drying drum, in addition to the temperature at which thedrying unit 110 is turned on and off. - Meanwhile, the bed sheets course may provide very, more, normal, less, and damp as the drying levels and the wool course may also provide very, more, normal, less, and damp as the drying levels. Each of the other drying courses may provide very, more, normal, less, and damp as the drying levels. However, there is no limitation thereto, and some drying courses may not provide the drying levels.
- In the drying level "very" in the bed sheets course, the drying time may be 95 minutes, and the drying time may be reduced as the level is changed to more, normal, less, and damp. In the drying level "very" in the wool course, the drying time may be 55 minutes, and the drying time may be reduced as the level is changed to more, normal, less, and damp.
- In addition, in
FIG. 4 , for convenience of description, it is illustrated that the drying level is divided by the drying time, but there is no limitation thereto. For example, the drying level may be divided by the drying end determination condition described above. For example, in the drying level "very" in the bed sheets course, the case where the number of times that the at least one sensor detects moisture for one minute is recorded as less than three times and this continued five times is the drying end condition, and the number of times in the case where the number of times that the at least one sensor detects moisture for one minute is recorded as less than three times may be reduced as the level is changed to more, normal, less, and damp. -

However, there is no limitation thereto, and theprocessor 120 may output a sound inquiring about the additional drying to the user through thespeaker 170. - The user may touch "OK" of
FIG. 5 to input the additional drying command. In this case, theprocessor 120 may control thedisplay 140 to display a message indicating that the additional drying operation is performed or output a sound indicating that the additional drying operation is performed through thespeaker 170. - In addition, referring to
FIG. 6 , the dryingapparatus 100 may include a first button 510 and asecond button 520, in addition to thedisplay 140. When the first button 510 is manipulated, theprocessor 120 may identify that the initial drying command is input, and when thesecond button 520 is manipulated, the processor may identify that the additional drying command is input. In addition, the dryingapparatus 100 may include a plurality of buttons and identify that the additional drying command is input by manipulation of two or more buttons. - However, there is no limitation thereto, and the
drying apparatus 100 may include a user interface in various forms and receive an input of the additional drying command. For example, the dryingapparatus 100 may include an interface in a form different from the button, such as a dial or the like, and identify that the additional drying command is input by the manipulation of dials. In addition, the dryingapparatus 100 may include a touch display and identify that the additional drying command is input by the manipulation of the touch display. -
FIG. 7 is a diagram illustrating an artificial intelligence model which identifies a type of a drying command according to an embodiment. - Referring to
FIG. 7 , theprocessor 120 may identify a type of the dryingcommand 730 by using a firstartificial intelligence model 720. Specifically, theprocessor 120 may obtain the type of the dryingcommand 730 as output data by inputting dryinghistory data 710 to the firstartificial intelligence model 720 as input data. Here, the dryinghistory data 710 may include at least one of weight information on the material to be dried, humidity information on the material to be dried, or opening and closing information of a door. Here, the material to be dried may include both the material to be dried during the previous drying operation and the current material to be dried. - The first
artificial intelligence model 720 may be a model trained on an external server. However, there is no limitation thereto, and theprocessor 120 may additionally train the trained firstartificial intelligence model 720 in real time. For example, even when the drying command is identified as the additional drying command through the firstartificial intelligence model 720, when a command for canceling the additional drying is input from the user, theprocessor 120 may update the firstartificial intelligence model 720 according to the canceling command. -
FIG. 8 is a diagram illustrating an artificial intelligence model which identifies a drying option according to an embodiment. - Referring to
FIG. 8 , theprocessor 120 may identify adrying option 830 using a secondartificial intelligence model 820.
