1 is a diagram showing an example of a system (hereinafter referred to as a dryer system) including an IOT-based smart clothes dryer according to the present invention. As shown in FIG. 1, the dryer system according to the present invention includes a clothes dryer 10 for drying user's laundry; a dryer server 30 for remotely managing the clothes dryer 10; and a user terminal 20 for communicating with the dryer server 30 or the clothes dryer 20 .

The user terminal 20 and the dryer server 30 and the clothes dryer 20 and the dryer server 30 are connected to each other through a network, and the user terminal 20 runs a dedicated application provided by the server side or system operator side. The clothes dryer 20 is also connected to the dryer server 30 through a network and transmits the event generator and dryer status information to the dryer server 30, and the dryer server 30 It is configured to receive commands from.

That is, the network or communication network serves to provide a path for information transmission and reception between the clothes dryer 10 , the user terminal 20 and the dryer server 30 . That is, the communication network refers to the clothes dryer 10, the user terminal 20, and the dryer management server in order to provide laundry and drying information such as drying start, drying end, expected drying time, and drying condition setting to the display unit of the user terminal. (30) It includes all data networks that enable data transmission and reception.

For example, a network that performs such a function is an IP network that provides large data transmission and reception services and data services without disconnection through the Internet Protocol (IP). It may be an All IP network, which is an integrated IP network structure. In addition, the network includes any one or one or more of a wired communication network, a mobile communication network, a Wibro (Wireless Broadband) network, a High Speed Downlink Packet Access (HSDPA) network, a satellite communication network, and a Wi-Fi (Wireless Fidelity) network. It may be a combined communication network that

2 is a diagram illustrating an example of a dedicated application provided to the user terminal 20 . As shown in FIG. 2 , the dedicated application includes a membership registration module 210, a barcode storage module 220, a barcode reading module 230, a dryer control module 240, and a server communication module 250.

The user terminal 20 accesses the dryer management server 30 through a dedicated application and registers as a member according to a predetermined procedure provided by the membership registration module 210 . When the user creates a personal identifier (ID) according to the membership registration procedure provided by the application, the server 30 generates a user-specific barcode and provides it to the user's application, and the barcode storage module 220 of the user application stores the server 30 Personal barcodes issued from

The user undergoes a reading operation of the barcode reader provided to the clothes dryer 10 through the assigned barcode, and when the barcode authentication is passed, the user can use the clothes dryer.

Also, the assigned barcode functions to allow the user to open the door of the dryer to check the state of the clothes being dried or to take out the clothes while the clothes dryer 10 is in use or after the drying operation of the clothes dryer is completed. This is the same as a lock function preventing other users from opening the door of the clothes dryer 10 .

That is, the clothes dryer 10 operates so that only the owner of the laundry can access the laundry stored in the dryer, thereby preventing the laundry from being stolen by another person or from being mixed with the laundry of other users.

The barcode reading module 230 may be used when a user wants to check state information of the clothes dryer 10 or information on a waiting list. For example, the user can check how many people are waiting to use the dryer. When the user reads the barcode (or QR code) attached to the corresponding clothes dryer 10 using the barcode reading module provided by the application and presses the waitlist confirmation button provided by the application, the clothes dryer 10 is the current dryer. The queue and expected waiting time of users who have made a reservation for use are displayed on the user's screen.

In addition to the user directly checking the waitlist using the barcode, the user remotely connects to the server through the server communication module 250 provided by the application and checks the waitlist information recorded in the server after accessing the server. and expected waiting time.

FIG. 3 is a diagram for explaining how to check the user's queue and expected waiting time from the server after the user accesses the server. As shown in FIG. 3, a user first accesses a server through an application installed in a user terminal. After accessing the server, the user clicks the "Reserve Use of Dryer" button provided in the dedicated application.

When the dryer management server 30 receives a request to use the dryer from the user, the dryer management server calls the list of clothes dryers 1 to 4 in the space where the user is located and creates a reservation user list for each dryer list called. In order to determine the location of the user, the dryer management server 30 may use GPS information of the user.

As shown in the list of waiting users or reserved users, the expected waiting time is displayed along with a list of waiting people. When the user selects a dryer to be dried by referring to the waiting list and the expected waiting time, the dryer management server 30 requests input of the weight of the laundry to be dried, and the user inputs the weight of the laundry to be dried. will enter.

The server calculates the expected drying time by applying its own calculation algorithm based on the weight of the laundry input by the user, and updates the waiting list of clothes dryers corresponding to the expected time together with the user's ID.

The dryer control module 240 operates so that a user can directly input drying settings of the dryer. For example, the user may input the drying temperature and drying time of the dryer through the dryer control module 240 . As will be apparent to those skilled in the art, the drying temperature and drying time may be input by the user through a control button provided in the clothes dryer.

If the user does not set the drying temperature and drying time of the dryer through the dryer control module 240, the clothes dryer 10 performs drying in the smart drying mode. The smart drying mode will be described in more detail in the section on the clothes dryer 10 .

The user may further check status information of laundry being dried from the dryer management server 30 through the server communication module 250 . For example, when the user selects the drying state check module, the server communication module 250 transmits the current progress from the drying clothes dryer, for example, the drying progress rate, the remaining time, the current temperature in the dryer, and the current interior of the dryer. It functions to receive information such as humidity and display it on the user's screen.

4 is a diagram schematically showing the configuration of the exterior of the IOT-based smart clothes dryer 10 used in the present invention. As shown in FIG. 4, the IOT-based smart clothes dryer 10 is provided as a stand-type dryer, unlike conventional drum-type dryers.

In the case of a conventional drum dryer, physical force is applied to clothes due to friction and falls generated when clothes rotate in the drum during the drying process, and significantly affects wrinkles, abrasion of clothes, and shrinkage of clothes. As shown in Fig. 5, it is composed of a dryer in the form of a stand in which laundry is hung by a hanger.

Again, as shown in FIG. 4, the front part of the clothes dryer 10 includes a display module 110 for providing the user with the current drying state (temperature, humidity, moisture content) of the laundry and information related to drying to the user; a user control panel 112 that functions to allow a user to select a desired drying temperature and drying humidity in a manual mode or a smart drying mode provided by an embodiment of the present invention; an identification code reader 113 for reading user identification codes (for example, barcodes and QR codes) provided to the user's terminal, and a camera module 114 for photographing user's laundry information; and a user handle 115 including a locking device.

In this configuration, the user first causes the identification code reader 113 to recognize a personal identification code stored in the user terminal 20, for example, a barcode. The identification information read through the identification code reader 113 is transmitted to the server, and the server determines whether a user to use is an authorized user and transmits it to the clothes dryer 10 .

The camera module 114 module is operated when the user wants to use the laundry in the smart drying mode. For example, when the user is determined to be a legitimate user through identification code recognition, the user can select a manual drying mode and a smart drying mode on the operation panel 112 according to information provided on the display module 110 .

When the user selects the smart drying mode, the display module 110 first instructs the camera module 114 to take a picture of a tag related to a fiber component provided in the laundry. After the textile component tag is photographed, guide information is displayed on the display module 110 to photograph the structure of the fabric using the camera module 114 . A user takes a picture of laundry fabric to be washed using a camera.

The moisture content of the fibers constituting the laundry is determined according to the inherent hydrophilic group that affects the drying time. That is, the drying time varies depending on the amount of moisture that the fiber can contain, and the drying mechanism is different. In general, the standard moisture content of cotton is 7%, wool is 16%, silk is 9-11%, and viscose rayon is 12-14%. The standard moisture content of spandex is less than 1%, and the amount of water retained after washing is significantly less than that of hydrophilic materials. In the present invention, a fiber component tag attached to clothing is photographed and the type of fiber of the laundry is determined through character recognition.

Clothing materials have different shrinkage during drying depending on the type of fiber, the structure of the yarn, the thickness of the yarn, and the twisting method. In particular, the clothing material changes its size or surface shape when it is used in the form of clothing. Types of dimensional deformation of clothing materials include elongation and contraction, and the main deformation is shrinkage.

Fibers undergo elastic elongation to return to their original length when the external force applied to the fibers is removed, but permanent deformation occurs as the force increases. This elongation phenomenon varies depending on the elastic recovery rate of the fiber, the modulus of elasticity, the thickness of the yarn, the twist, the density of the yarn, the thickness, etc., and the deformation occurs much more easily in a knitted fabric having a higher degree of freedom than in a fabric. In the present invention, by photographing the fabric structure of fibers forming clothing, factors such as fabric structure, fiber thickness, twist, yarn density, and yarn thickness are identified through image analysis.

In the present invention, shrinkage, expansion, skewness, and wrinkles of clothes are considered in consideration of factors including the type of fibers constituting the clothes, drying temperature, drying time, humidity, etc. to prevent physical deformation occurring during the drying process of the clothes. It is configured to prevent the back.

After the user photographs the textile component tag and fabric structure of the clothes through the camera module 114 according to the guidance information provided from the display module 110, the user hangs the clothes on a hanger inside the dryer.

A locking device 1151 is provided inside the handle 115, and the door of the dryer is locked to the main body of the dryer by the locking device. The locking device provided on the handle may be locked/unlocked by the user matching unit 151.

5 is a view showing an internal shape of the clothes dryer 1 in a state in which the dryer door 101 is opened. As shown in FIG. 5 , the clothes dryer 1 includes a temperature sensor 1181 , a humidity sensor 1182 , a weight sensor 1183 , and a droplet sensor 1184 .

The temperature sensor 1181 is provided to measure the temperature of the inner space of the dryer and the humidity sensor 1182 is provided to measure the temperature of the inner space of the dryer. The controller 150 of the dryer reads the temperature and humidity values from the temperature sensor 1181 and the humidity sensor 1182 to adjust the strength of the heater, blower, and vibration motor 130 of the dryer.

A hanger 1301 for hanging laundry is provided in the inner space of the dryer, and one shaft of the hanger is connected to the vibration motor 130 as shown. In addition, the hanger 1301 and the motor assembly 130 are simultaneously supported by a weight sensor 1183 provided below the hanger 1301 to measure the weight of laundry when laundry is caught on the hanger 1301. As moisture evaporates during the drying process, the weight of the laundry gradually changes, and the control unit can predict the drying end time through the change in the weight of the laundry, the moisture content of the fabric detected through the camera module, and the change in humidity in the dryer. .

The hanger 1301 functions as a support for accommodating clothes inside the dryer, and is connected to the vibration motor 130 to continuously vibrate during drying, and the vibration of the hanger is transmitted to the clothes hung on the hanger during the drying process. Moisture contained in the clothes moves to the lower side by vibration force and gravity.

In the case of clothes containing a lot of moisture, the moisture that is not evaporated by the hot air falls to the lower part of the clothes dryer in the form of water droplets. In the present invention, a drain 140 for accommodating such water droplets is provided at the bottom of the dryer, and a drain 141 connected to the outside is connected to one side of the drain, and a droplet sensor 1184 is connected to the bottom of the drain. is installed Water droplets or moisture falling from the clothes are first sensed by the droplet sensor 1184 and then discharged through the drain, preventing the water contained in the drain container 140 from being vaporized during the drying process, thereby preventing unnecessary waste of energy. The amount of water droplets sensed by the droplet sensor is used to determine the location and speed of the air volume applied to the clothing.

The hanger 1301 may use a heat-resistant material for enduring high-temperature heat, for example, a silicon material or a metal material molded with a silicon material. In addition, the vibration transmitted to the clothes by the vibration motor 130 performs the vibration to move the water contained in the clothes to the lower side of the clothes as described above, and this vibration movement helps to prevent the clothes from being wrinkled.

6 is a side view of the clothes dryer 10 . As shown in FIG. 6 , the clothes dryer 10 has an air inlet 191 provided at the lower side and an air outlet 192 provided at the upper side. The air introduced through the dryer air inlet 191 is heated by the heater means 150, and the heated high-temperature air moves through the air passage 193 formed at the rear of the dryer. The hot air introduced into the air passage is supplied to the inside of the dryer by a blower or blowing means 162 formed in the air passage, and the high-temperature drying air entering the inside of the dryer heats the laundry and generates steam (moisture) generated from the laundry. The air containing is discharged to the outside through the exhaust port 192 by the action of the exhaust fan 164.

Blowing means 162 are provided in a plurality of places inside the dryer. For example, as shown in FIG. 6, the blowing means (162: 1621, 1622, 1623) are formed in at least three places along the height direction of the dryer.

The plurality of blowing means 162 are controlled by the dryer control unit 150 and configured to be individually controllable. In an embodiment of the present invention, a droplet sensor 1184 is provided at the bottom of the laundry, and the amount of water droplets falling from the laundry is calculated by the droplet sensor. For example, during the initial drying operation when the drying operation starts, the number of drops of water droplets sensed by the droplet sensor 184 is large. Accordingly, all of the plurality of blowing units 162 (1621, 1622, and 1623) may be configured to perform a blowing operation. This is because even if the vibration by the vibration motor starts, the moisture contained in the clothes is maintained evenly throughout the clothes in the initial drying period.

However, during the intermediate drying process, the number of detections of droplets detected by the droplet sensor 1184 is reduced because the amount of moisture contained in the clothes decreases and the amount of moisture gradually permeated to the bottom by vibration decreases. In this case, among the plurality of blowing means (162: 1621, 1622, 1623), only the blowing means (1622) at the middle height and the blowing means (1621) located at the lowest position perform air blowing, and the blowing means (1623) at the upper side performs the blowing operation. may not be performed or the intensity of blowing may be operated weakly compared to other blowing means.

At the end of the drying operation, the number of detected droplets from the droplet sensor 1184 is reduced or not detected. At this time, most of the moisture contained in the clothes exists on the lower side due to vibration. Accordingly, in this case, only the blowing unit 1621 located at the lowermost side performs the blowing operation, and the other blowing units 1622 and 1623 may stop the blowing operation or operate weakly with relatively small intensity.

FIG. 7 is a diagram schematically illustrating the configuration of the control unit 150 of the clothes dryer 10 according to the present invention, and FIG. 8 is a flowchart showing the operation flow of the dryer by the control unit. The configuration and operation of the control unit will be described below with reference to FIGS. 7 and 8 . As shown, the control unit 150 includes a user matching unit 151 for unlocking/locking the locking device; a user identification unit 152 for verifying whether the user is an authorized user through the identification code read from the identification code reader 152; a waiting list creation unit 153 for creating and storing a waiting list of users who want to use the dryer; a drying condition receiver 154 for receiving information from external sensors, for example, the weight sensor 117, the camera module 114, and the control panel 112; a smart drying controller 155 that controls smart drying according to the received drying conditions; a heater/motor/blower driving unit 156 for driving a heater/motor/blower (blowing fan, exhaust fan) under the control of the smart drying controller 155; A drying state monitoring unit 157 monitoring the drying state according to internal temperature sensors 1181 and 1182 is included.

With the dryer configured in this way, the user identification unit 152 first transmits the identification code read from the identification code reader 113 to the dryer management server 30 through the communication module 158, and the dryer management server 30 Confirm the authenticity of the identification code from If it is determined that the identification code is a normal user, the user confirmation unit 152 proceeds to an operation standby state for receiving the user's input.

If the clothes dryer 10 is in use, the control unit provides a list of currently waiting users to the user through the display module and indicates whether or not to proceed with standby reservation. When a user makes a standby reservation, the control unit adds and updates the identification code (or ID) of the user to the waiting list through the waiting list preparation unit 153, and sends the updated waiting list (waiting list) to the dryer management server 20. will be sent

The drying condition receiving unit 154 receives whether the user selects a manual drying mode or a smart drying mode through the operation panel. If the user selects the manual drying mode, the control unit displays the input of the drying temperature and drying time on the display module, but if the user selects the smart drying mode, the camera module 114 provides the user with clothing tag information and clothing fiber information. It instructs to photograph the tissue, and transmits the photographed tag photo and clothing fiber tissue to the smart drying control unit 155.

The smart drying control unit 155 performs text recognition on the photographed tag information to extract the fiber components of the laundry clothes, and also analyzes the image of the textile structure photos to determine the fabric structure (knitting structure) of the clothes, the thickness of the fibers, Twist, yarn density, and yarn thickness are determined.

Thereafter, the smart drying control unit 155 uses information including the analyzed information, fiber components, fabric structure (knitting structure), fiber thickness, twist, yarn density, and yarn thickness to determine the internal temperature of the dryer and the interior of the dryer for each time period. At the same time as creating a profile for humidity, the internal temperature and humidity are changed to suit the configuration of the laundry to be dried by driving the heater, blower (blowing fan, discharge fan), and vibration motor driving unit according to the corresponding profile. It controls the frequency of the motor, the speed of the blowing fan and the exhaust fan, and the temperature of the heater.

The drying state monitoring unit 157 is configured to calculate an estimated drying completion time of the laundry using the temperature data and humidity data acquired from the temperature and humidity sensors 1181 and 1182 and monitor the current drying state of the laundry, and complete the drying process. 10 minutes prior to the expected time, the smart drying control unit 155 is notified (drying expected notification).

The smart drying control unit 155 notifies the management server 30 of receiving the drying forecast notification from the drying state monitoring unit 157, and the management server notifies the users of the current laundry dryer and those waiting for the next dryer that 10 minutes have passed. do.

Currently, a laundry user must take out dried laundry from a corresponding clothes dryer when drying is completed after receiving a drying prediction notification. In order to take out the dried laundry from the dryer, the user must go through a process of scanning the identification code stored in the user terminal 20 with an identification code reader. After the user scans the identification code, the user matching unit 151 of the control unit 150 checks whether the scanned identification code matches the identification code scanned in the laundry drying start operation, and if it is the same as the previously scanned identification code, the lock device ( 1151) is unlocked.

After drying is completed, if a predetermined time (for example, 5 minutes) has elapsed without the user taking out the dried laundry, the controller 150 notifies the dryer management server 20 of this, and the dryer management server 20 ) notifies the applicable user of penalty information that results in additional charges or restrictions on the use of the dryer from the time when the application of the corresponding user has elapsed more than 5 minutes later.

Meanwhile, after drying is completed, if there is no barcode input from the next user for a certain period of time (eg, 5 minutes) after the laundry user takes out all the dried laundry, the controller 150 of the dryer controls the dryer management server 20 ), and the dryer management server 20 notifies the next user's application that it will be deleted from the user waiting list if 5 more minutes pass. If the dryer is deleted from the standby list, the user must make a standby reservation again in order to use the dryer.

Also, after drying is completed, when a laundry user takes out all the dried laundry and a non-top priority waiter scans an identification code to use the dryer in the waiting list, the user matching unit of the control unit 150 scans and inputs The identification code is compared with the identification code of the highest priority in the queue, and a discrepancy occurs as a result of the comparison, and since the controller 150 does not operate the clothes dryer, a drying operation is not performed.

As described above, according to an embodiment of the present invention, according to the IoT-based clothes dryer, a drying profile optimized for a drying target is determined using fiber information such as components, fabric density, knitting structure, twist, and yarn thickness of the fabric to be dried. Optimized drying can be carried out by generating and drying accordingly.

In addition, according to an embodiment of the present invention, it is possible to solve the problem of washing laundry of users being mixed or lost in places such as hospitals, military units, and dormitories shared by many users. Problems such as shrinkage and deformation can be minimized.

As described above, although the embodiments have been described with limited drawings, those skilled in the art can make various modifications and variations from the above description. For example, the described techniques may be performed in an order different from the method described, and/or components of the described system, structure, device, circuit, etc. may be combined or combined in a different form than the method described, or other components may be used.
