BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to apparatus and method for controlling a washing/drying system, and more particularly, to apparatus and method for controlling a washing/drying system in which a dryer operates based on washing information performed in a washing machine. Further, the present invention relates to apparatus and method for controlling a washing/drying system in which when a washing machine and a dryer are adjacent to each other and are independently used, operation information used in operating the washing machine is used in operating the dryer, thereby more conveniently and simply manipulating and operating the dryer.
2. Description of the Related Art
A washing machine washes laundry received in a drum using rotation of the drum. The pulsator type washing machine, the agitator type washing machine, the drum type washing machine and the like have been well known to those skilled in the art. A dryer is used to completely remove moisture remaining in laundry that the dewatering cycle is completed, using hot air.
In detail, the dryer blows hot air generated by a heater into the drum to absorb moisture from laundry to be dried. The dryer can be classified into an exhaust type dryer and a condensed type dryer. The exhaust type dryer exhausts wet air discharged from the drum to an outside of the dryer, and the condensed type dryer condenses wet air discharged from the drum at a condenser to remove moisture from the wet air and convert the wet air into dry air and again blows the dry air to the drum to recycle the air.
Meanwhile, the conventional washing and drying cycles are continuously performed in once washing operation. In other words, laundry washed in the washing machine is directly received in the dryer to perform drying. Thus, to continuously perform the washing and the drying, the washing machine and the dryer are disposed adjacent to each other. In addition, information acquired or inputted while the washing machine operates is transmitted to the dyer through wiring communication to allow a user to operate the dryer more conveniently, which is well known to those skilled in the art.
However, the wiring communication causes many inconveniences for a user. For instance, the user has to connect a wiring cable and a separate space for installation of the cable is required. Also, displacement of the washing machine and the dryer is allowable only after the cable is separated, which makes inconvenient users.
Recently, as the inner space is getting narrow and narrow, the washing machine and the dryer are frequently used in stack structure. In such a stack structure, it is general that the washing machine having heavy weight due to use of much amount of water is disposed above the dryer having light weight.
However, when the washing machine and the dryer are used in the stack structure, a user feels inconvenience because the user's hand does not reach a manipulation panel disposed at an upper side of the dryer. Also, it can be considered that the manipulation panel is disposed at a lower portion of the dryer for the convenience of use, which makes convenient the user in the stack structure but makes inconvenient the user in a parallel structure where the washing machine and the dryer are disposed in parallel.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to apparatus and method for controlling a washing/drying system that substantially obviates one or more problems due to limitations and disadvantages of the related art.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
First Embodiment
FIG. 1 is a perspective view of a washing/drying system employing a control system according to a first embodiment of the present invention.
Referring to FIG. 1, the washing/drying system includes a washing machine 10, a manipulation panel 11 formed at a predetermined portion of the washing machine 10, for inputting instructions such as kinds of laundry, washing method and the like, and a washing machine antenna 12 formed at a predetermined portion of the washing machine 10.
The washing machine 10 can include all kinds of washing machines irregardless of the kinds of the washing machines. The washing machine antenna 12 is preferably formed at an invisible rear side of the washing machine 10. However, the installation site of the washing machine antenna 12 is not limited to the aforementioned invisible rear side.
Meanwhile, the dryer 20 includes a manipulation panel 21 formed at a predetermined portion of the dryer 20 and manipulated by a user, and a second antenna 22 formed at a predetermined portion of the dryer 20.
The washing machine antenna 12 transmits laundry-related information instructed by a user or known during the operation of the washing machine, to the dryer antenna 22. Also, the dryer antenna 22 receives information transmitted through the washing machine antenna 12. Accordingly, if necessary, the washing machine manipulator 11 operates as the dryer manipulator 21 such that operation information of the dryer is inputted by the washing machine manipulator 11 and is then wirelessly transmitted to the dryer manipulator 21.
All kinds of communication regulations including an infrared communication regulation, a supersonic communication regulation, a radio frequency (RF) communication regulation, and a Bluetooth communication regulation can be allowed for wireless communication between the washing machine antenna 12 and the dryer antenna 22.
FIG. 2 is a perspective view illustrating that a washing machine and a dryer are used in a stack structure according to the first embodiment of the present invention.
Referring to FIG. 2, the dryer 20 is disposed on the washing machine 10. Like in FIG. 1, the washing machine manipulator 11 for instructing kinds of laundries, washing methods and the like at the user is formed at a front upper side of the washing machine 10 and the dryer manipulator 21 manipulated by the user is formed at a front upper side of the dryer 20.
As will be seen from FIGS. 1 and 2, the washing machine 10 and the dryer 20 are disposed in parallel in a horizontal direction or in a stack structure. However, since the washing machine and the dryer operate in a wireless communication, the arrangement of the washing machine and the dryer does not influence a control of the washing machine and the dryer.
FIG. 3 is a block diagram of an apparatus for controlling a washing/drying system according to the first embodiment of the present invention.
Referring to FIG. 3, the washing machine 10 includes a washing machine manipulator 11 for inputting a manipulation signal to the washing machine 10 at a user, a user interface 13 for determining the manipulation signal inputted through the washing machine manipulator 11, and a washing machine controller 14 for determining the manipulation signal inputted through the user interface 13 to control the washing machine 10 such that the washing machine 10 operates in a proper condition.
Also, the washing machine 10 further includes load elements controlled by the washing machine controller 14, i.e., a motor 17 for rotating a drum of the washing machine, a valve 16 for adjusting supply of water and detergent to the washing machine, and a sensor for sensing information related with washing water and laundry. The washing machine 10 also includes a memory 15 for storing washing-related information including the information related with the washing water and laundry sensed by the sensor 18 and information inputted through the washing machine manipulator 11 at the user.
In addition, the washing machines further includes a wireless washing machine communication part 19, which converts the washing information stored in the memory 15 into a signal adapted for a wireless communication regulation such that the washing information can be transmitted to the dryer 20. Of course, the information of the wireless washing communication part 19 is transmitted to the dryer 20 through the washing machine antenna 12.
Meanwhile, the dryer 20 includes a dryer antenna 22 for wirelessly receiving information wirelessly transmitted through the washing machine antenna 12, and a wireless dryer communication part for converting the information received through the dryer antenna 22 into information necessary for the operation of the dryer 20. In addition, the dryer 20 includes a manipulator 21 for inputting a manipulation signal instructed by the user for the operation of the dryer, a user interface 23 for inputting the manipulation signal of the manipulator 21 to a dryer controller 24, and a memory 25 for storing information related with the operation of the dryer 20.
Also, the dryer 20 further includes load elements controlled by the dryer controller 24, i.e., a motor 28, a heater 29 and a fan 26. Specifically, the motor 28 rotates a drum so as to uniformly dry the laundry, the fan 26 forcibly blows outer air to an inside of the dryer such that the blown air flows, and the heater 29 heats the air blown to the inside of the dryer 20 up to a proper temperature such that the laundry is more rapidly dried.
A method for controlling the aforementioned washing/drying system will now be described in brief.
When the user intends to use the washing machine, laundry is loaded into the inside of the washing machine and the user inputs known facts related with the laundry. The input information can include various types, for example, information related with the kinds of laundry (nylon, cotton, wool and the like), information regarding supply amount of detergent, and information related with operation time of the washing machine. The informations can be inputted by the user's determination.
The information inputted by the user is used to operate the washing machine as soon as the user operates the washing machine. As the washing machine operates, the washing machine can sense information related the laundry during an initial operation, for example, weight, volume and the like of the laundry, and the sensed information can be also used for the operation of the washing machine.
Base on the information related with the kinds of laundry, the information related with supply amount of detergent, and the information related with operation time of the washing machine, the washing machine performs washing, rinsing and dewatering cycles. As the operation of the washing machine is ended, the user loads the washed laundry into the dryer 20 and operates the dryer 20. Before the laundry is loaded into the dryer and the dryer operates, the step of wirelessly transmitting the information stored in the washing machine to the dryer is performed, so that the user can operate the dryer more conveniently.
Based on the information transmitted from the washing machine to the dryer, an optimal operation condition of the dryer can be selected. After the optimal operation condition of the dryer 20 is confirmed, the user corrects the operation information of the dryer 20. After such a correction is performed, the dryer operates to start the drying of the laundry. At this time, the heater 29, the fan 26 and the motor 28 operate. Based on the inner information of the dryer inputted from the sensor 27, the drying status of the laundry in the dryer is caught and the operation cycles of the dryer can be adjusted in detail.
Hereinafter, a method for controlling the dryer according to the present invention will be described in detail.
FIG. 4 is a flow diagram illustrating a method for controlling a washing/drying system according to the first embodiment of the present invention. In FIG. 4, it is assumed that all cycles of the washing operation have been completed.
Referring to FIG. 4, when all cycles of the washing operation are completed in the washing machine 10, the washing machine 10 wirelessly transmits a connection request signal to the dryer 20. (S11) After receiving the connection request signal, the dryer 20 enters a reception standby mode and transmits a signal informing that the dyer 20 is in the standby mode to the washing machine 10. (S12) Thereafter, the washing machine processes the information sensed during the washing operation of the washing machine or the information known by the user's input to generate a wireless data. (S13) Then, the washing machine 10 wirelessly transmits the generated wireless data to the dryer 20. (S14) Specifically, the wireless data obtained by processing the information stored in the memory 15 at the wireless washing machine communication part 19 is transmitted through the antenna 12.
At the dryer 20, the antenna 22 receives the information wirelessly transmitted from the washing machine, and the wireless dryer communication part 30 processes the received information to convert the received information into information usable in the dryer 20. The converted information is stored in the memory 25 of the dryer 20 and can be used for the operation of the dryer 20 later. (S15)
The above operations Sl1 through S15 can be performed whenever after all information necessary for the operation of the washing machine is stored and before the operation of the dryer starts. In detail, the above operations S11 through S15 can be performed when the washing cycles of the washing machine 10 are completed, when a door of the washing machine is opened, or when the washed laundry is loaded into the dryer.
Through the above operations, if the information used during the operation of the washing machine is wirelessly transmitted to the dryer 20, the dryer 20 is operatable and enters the operation standby mode. As the user starts the operation of the dryer 20 (S16), the information stored in the memory 25 is processed and the operation of the dryer 20 starts. However, if the operation of the dryer 20 does not start even after elapse of a predetermined time, it is determined that the laundry is not loaded into the dryer 20 but is naturally dried or only the operation of the washing machine is performed. Therefore, the information stored in the dryer memory 25 is deleted and all control methods are ended. (S17)
In the meanwhile, if the operation of the dryer starts after the elapse of a predetermined time, an optimal operation condition suitable for the operation of the dryer 20 is determined based on the information stored in the dryer memory 25. (S18) The optimal operation condition includes the information related with the kinds of laundries, the information related with the supply amount of detergent, the information related with the operation time of the washing machine and the information related with the amount of laundry, which are wirelessly transmitted to the dryer 20 from the washing machine 10.
If the optimal operation condition of the dryer 20 is determined, a control signal for operating each load of the dryer 20 is generated (S19) and the operation of the dryer 20 is performed. (S20)
Meanwhile, prior to initiating the operation of the dryer 20, the user may observe the optimal operation condition automatically determined to correct the optimal operation condition through the dryer manipulator 21.
According to the proposed method for controlling the dryer, since the washing information of the washing machine can be conveniently transferred to the dryer, user convenience can be further enhanced.
Second Embodiment
The second embodiment according to the spirit of the present invention is the same in many parts as the first embodiment but has a main difference in that the position of the dryer manipulator is varied. Accordingly, sufficient description can be understood with reference to the description disclosed in the first embodiment.
FIG. 5 is a perspective view illustrating use of a washing/drying system according to a second embodiment of the present invention.
Referring to FIG. 5, a dryer 40 is disposed on a washing machine 33. Since the washing machine 33 has a washing machine antenna 12 and the dryer 40 has a dryer antenna 42, a wireless communication can be performed between the washing machine 33 and the dyer 40.
In detail, the washing machine 33 includes a door 31 formed at a front side of the washing machine 33, through which laundry is loaded, and a washing machine manipulator 32 formed at a front upper side of the washing machine 33, for controlling operation of the washing machine at a user. Meanwhile, the dryer 40 includes a case 49 forming the exterior of the dryer 40, a door 41 used for loading washed laundry, and a dryer manipulator 42 for manipulating the dryer 40. The position of the dryer manipulator 42 may be changed to another position. Although FIG. 5 does not show a drum, a motor and the like that are essential elements for the washing machine 33 and the dryer 40, it is natural that such elements are equipped in the insides of the washing machine 33 and the dryer 40.
In detail, the dryer manipulator 42 may be selectively mounted on a first receiving part 43 formed at an upper side of the dryer 40 or on a second receiving part 44 formed at a lower side of the dryer 40. The dryer manipulator 42 is made in the form of a separatable structure such that the dryer manipulator 42 is selectively mounted on any of the first receiving part 43 and the second receiving part 44.
Also, the dryer 40 includes a display part 50 formed at a predetermined portion of a front side of the dryer 40 such that the user observes the operation of the dryer 40, a manipulation button part 51 used for performing a control operation of the dryer 40, and a second connection terminal 47 formed at a predetermined portion of the dryer manipulator 42 for an electrical signal transmission between a main body of the dryer 40 and the dryer manipulator 42.
In addition, each of the fist receiving part 43 and the second receiving part 44 includes a first connection terminal 48 connected with the second connection terminal 47 to electrically connect the main body of the dryer 40 with the dryer manipulator 42 each other such that a predetermined signal communicates between the main body of the dryer 40 and the dryer manipulator 42, and first and second guide ribs 45 and 46 for fixing the position of the dryer manipulator 42 inserted into and mounted on the first receiving part 43 or the second receiving part 44. Each of the fist receiving part 43 and the second receiving part 44 further includes a latch such that the dryer manipulator 42 inserted into the first receiving part 43 or the second receiving part 44 is not released from the first receiving part 43 or the second receiving part 44.
The latch includes a second latch 54 formed at a predetermined portion of the dryer manipulator 42, and a first latch 53 formed at a predetermined portion of an inside of the first receiving part 43 or the second receiving part 44 and latched with the first latch 54. The first and second latches 53 and 54 are formed at positions corresponding to each other such that the dryer manipulator 42 is completely inserted into and coupled with the first receiving part 43 or the second receiving part 44.
Also, the first and second guide ribs 45 and 46 are formed at the front surface of the first receiving part 43 and the second receiving part 44 such that the dryer manipulator 42 is received in and is not released from the first receiving part 43 or the second receiving part 44.
Operation of the washing/drying system proposed in the second embodiment of the present invention will now be described with reference to the accompanying drawing.
As shown in FIG. 5, when the washing machine and the dryer are disposed in the stack structure, the dryer manipulator 42 is inserted into and mounted in the inside of the second receiving part 44 formed at the lower side of the dryer 40. Accordingly, the user can manipulate the dryer using the dryer manipulator 42 which is leveled at a similar height to the washing machine manipulator 32 and does not feel inconvenience due to the height of the dryer manipulator 42. In addition, when the washing machine and the dryer are disposed in parallel in a horizontal direction, the dryer manipulator 42 is inserted into and mounted in the first receiving part 43. At this time, since the dryer manipulator 42 is positioned at a proper height, the user can operate the dryer conveniently.
The second connection terminal 47 is formed at the predetermined portion of the dryer manipulator 42 and the first connection terminal 48 is formed at the inside of the first receiving part 43 or the second receiving part 44 such that the first connection terminal 48 is connected with the second connection terminal 47 after the dryer manipulator 42 is mounted in the first receiving part 43 or the second receiving part 44.
The second connection terminal 47 and the first connection terminal 48 are aligned in series after the dryer manipulator 42 is completely mounted in the inside of the first receiving part 43 or the second receiving part 44. By doing so, a signal of the dryer manipulator 42 is normally transmitted to the main body of the dryer 40, so that the operation of the dryer can be performed. Also, after the dryer manipulator 42 is mounted in the inside of the first receiving part 43 or the second receiving part 44, the second latch 54 of the dryer manipulator 42 is latched with the first latch 53. Accordingly, the dryer manipulator 42 is not released from the first receiving part 43 or the second receiving part 44 if a power exceeding a critical pulling force is not applied.
Thus, since the dryer manipulator 42 can be variably disposed at any of the upper side and the lower side of the dryer 40, the user can handle the dryer manipulator 42 easily and manipulate the dryer conveniently even though the dryer is disposed in the stack structure or in the parallel structure. Alternatively, the dryer manipulator may be formed at both of the lower side and the upper side of the dryer.
In particular, the present embodiment can be conveniently applied to the stack structure of the washing machine and dryer irregardless of whether information is wirelessly transmitted from the washing machine to the dryer. However, the dryer can be used more conveniently when the information of the washing machine is wirelessly transmitted to the dryer.
FIG. 6 is a sectional view taken along the line I-I′ of FIG. 5.
Referring to FIG. 6, the dryer 40 includes an inner case 52 concavely formed inside the case 49, a first latch 53 protrudedly formed from an outer surface of the inner case 52, the first connection terminal 48 formed inside the first receiving part 43 and aligned with the second connection terminal 47, and the first and second guide ribs 45 and 46 enabling a user to observe the dryer manipulator 42 from an outside.
According to the above embodiment, since the dryer manipulator can be conveniently mounted at the upper side or the lower side of the dryer, when the washing/drying system is disposed in the stack structure, it can be apparently understood that the washing/drying system can be more conveniently used.
Third Embodiment
The third embodiment according to the spirit of the present invention is the same in many parts as the first embodiment but has a main difference in that a user can directly manipulate a dryer using a washing machine. Accordingly, insufficient description can be understood with reference to the description disclosed in the first embodiment.
FIG. 7 is a block diagram of an apparatus for controlling a washing/drying system according to a third embodiment of the present invention.
Referring to FIG. 7, the washing machine 10 includes a washing machine manipulator 11 for inputting a manipulation signal to the washing machine 10 at a user, first and second user interfaces 13 and 90 for determining the manipulation signal inputted through the washing machine manipulator 11, a washing machine controller 14 for determining the manipulation signals inputted through the user interfaces 13 and 90 to control the washing machine 10 such that the washing machine 10 operates in a proper condition, and a switch 91 for selectively inputting the manipulation signal inputted through the manipulator 11 into the first user interface 13 or the second user interface 90. For instance, the first user interface 13 can be used as the interface for the operation of the washing machine, and the second user interface 90 can be used as the interface for the operation of the dryer.
Meanwhile, since the dryer has the same elements as those in the first embodiment, their description can quote from that of the first embodiment.
Hereinafter, the operation of the apparatus for controlling the washing/drying system will be described.
When the user intends to use the washing machine, laundry is loaded into the inside of the washing machine and the user inputs known facts related with the laundry. The input information can include various types, for example, information related with the kinds of laundry (nylon, cotton, wool and the like), information regarding supply amount of detergent, and information related with operation time of the washing machine. The informations can be inputted by the user's determination.
The information inputted by the user is used to operate the washing machine as soon as the user operates the washing machine. As the washing machine operates, the washing machine can sense information related the laundry during an initial operation, for example, weight, volume and the like of the laundry, and the sensed information can be also used for the operation of the washing machine. When the user inputs information for the operation of the washing machine through the manipulator 11, the switch 91 makes the manipulator 11 and the first user interface 13 connected with each other.
Base on the information related with the kinds of laundry, the information related with supply amount of detergent, and the information related with operation time of the washing machine, the washing machine performs washing, rinsing and dewatering cycles. As the operation of the washing machine is ended, the user loads the washed laundry into the dryer 20 and operates the dryer 20. Before the laundry is loaded into the dryer and the dryer operates, the step of wirelessly transmitting the information stored in the washing machine to the dryer is performed, so that the user can operate the dryer more conveniently.
The user can input control information for controlling the dryer through the washing machine manipulator 11 and the control information can be stored in a memory 15. At this time, the switch 91 connects the manipulator 11 with the second user interface 90. For this operation, the switch 91 is formed at a predetermined position of the washing machine.
Further, the information wirelessly transmitted from the washing machine to the dryer may include information known during the operation of the washing machine as well as the control information of the dryer inputted by the user.

Referring to FIG. 10, when all cycles of the washing operation are completed in the washing machine 10, washing-related information is stored and the washing machine 10 wirelessly transmits a connection request signal to the dryer 20. (S21) After receiving the connection request signal, the dryer 20 enters a reception standby mode and informs the washing machine 10 of such a fact that the dyer 20 is in the standby mode. (S22)
Thereafter, the washing machine processes the information sensed during the washing operation of the washing machine, and then wirelessly transmits the processed information to the dryer 20. (S23) The dryer 20 receives the information wirelessly transmitted from the washing machine and stores the received information in the memory 25 of the dryer 20, which will be used for the operation of the dryer 20. (S24)
As the user starts the operation of the dryer 20 (S25), the information stored in the memory 25 is processed and the operation of the dryer 20 starts. However, if the operation of the dryer 20 does not start even after elapse of a predetermined time, it is determined that the laundry is not loaded into the dryer 20 but is naturally dried or only the operation of the washing machine is performed. Therefore, the information stored in the dryer memory 25 is deleted and all control methods are ended. (S26)
In the meanwhile, if the operation of the dryer starts before the elapse of a predetermined time, the control information of the washing machine stored in the dryer memory 25 is transmitted to the remote controller. (S27) In the step S27, the dryer controller 24 may determine and transmit the optimal operation condition of the dryer to the remote controller 93 based on the specification of the dryer and the control information of the washing machine.
After viewing the information displayed on the display part of the remote controller, the user selects and determines the operation status of the dryer and operates the dryer. (S28) After that, the remote controller generates a control signal for driving each of the elements of the dryer and deletes the control information of the washing machine stored in the remote controller. (S29) Thereafter, the step of initiating the operation of the dryer is performed. (S30)
According to the proposed control method, it is possible to operate the washing/drying system more conveniently. Also, according to the present embodiment, since the operation information of the dryer can be monitored more conveniently, the optimal operation status can be determined and conveniently transmitted to the dryer, user convenience can be further enhanced.
