This application claims the benefit of Korean Patent Application No. 10-2018-0139308, filed on Nov. 13, 2018 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
The present disclosure relates to a clothes handling apparatus, and more particularly, to a clothes handling apparatus that allows a user to easily change a door opening direction (left hand opening or right hand opening).
Generally, a clothes handling apparatus may include a washer which washes clothes and a dryer which dries the clothes.
The washer may include a rotatable drum and remove contaminants (foreign substances) attached to clothes by using a mechanical action by rotation of the drum and a chemical action by a detergent. The washer may be a front loading type in which an opening for putting laundry (load) in the drum is provided at a front surface of a main body of the washer or may be a top loading type in which the opening is provided at an upper surface of the main body of the washer.
The dryer may also include a rotatable drum and remove moisture from clothes using a mechanical action by rotation of the drum and a high-temperature dry hot air. Nowadays, most dryers are a front loading type in which an opening for putting laundry (load) in the drum is provided at a front surface of a main body of the dryer.
A user may use a front-loading type washer and a front-loading type dryer together.
In this case, for convenience of the user, a door opening direction of the washer and a door opening direction of the dryer may be different. For example, when the washer is disposed at the left side of the dryer and the dryer is disposed at the right side of the washer, the washer may include a left hand opening door which opens from the left side, and the dryer may include a right hand opening door which opens from the right side.
Generally, a washer and a dryer each include a left hand opening door which opens from the left side. Therefore, for convenience of a user, a left hand opening door of any one of a washer and a dryer may be changed to a right hand opening door which opens from the right side.
In the conventional washer and dryer, since a front panel of a main body has to be removed to change a left hand opening door to a right hand opening door, it is difficult for a user to change a door opening direction by himself or herself.
Therefore, it is an aspect of the present disclosure to provide a clothes handling apparatus that allows a user to easily change a door opening direction.
It is an aspect of the present disclosure to provide a clothes handling apparatus that allows a user to change a door opening direction without removing a front panel of a main body.
It is an aspect of the present disclosure to provide a clothes handling apparatus that allows a door to be locked even when a user changes an opening direction of the door.
It is an aspect of the present disclosure to provide a clothes handling apparatus that includes a pair of door locking devices installed at both sides of an opening for putting clothes in a drum.
It is an aspect of the present disclosure to provide a clothes handling apparatus in which a pair of door locking devices are formed to be symmetrical to each other.

A dryer 100 is one kind of clothes handling apparatuses.
The dryer 100 refers to an apparatus which rotates a drum accommodating an object to be dried and supplies high-temperature air into the drum to dry the object to be dried. Here, the object to be dried encompasses any object which may be dried by high-temperature air. For example, the object to be dried is not limited and may be any object made of various kinds of fibers and fabrics, such as clothes and towels.
As illustrated in
The cabinet 101 may include a base plate 102, a front cover 103, a top cover 104, and a side-rear cover 105.
The user input device 110 and the display 115 for control of the dryer 100 may be disposed at an upper end of the front cover 103.
The user input device 110 may include a dial 111 which is gripped and rotated by a user to input a control command related to an operation of the dryer 100 and a button 112 which is pressed by the user to input a control command related to an operation of the dryer 100.
For example, the dryer 100 may include different drying courses for drying different objects to be dried, and the user may select any one of a plurality of drying courses by rotating the dial 111.
Also, the dryer 100 may include a power button for permitting or interrupting power supplied from an external power supply and an operational button for starting or stopping a drying operation of the dryer 100. The button 112 may include a push switch and a membrane switch, each of which is operated by being pressed by the user, or include a touch switch or the like which is operated by being in contact with a part of the user's body.
However, the user input device 110 is not limited to including the dial 111 and the button 112 and may include any means that allow a user to input a control command related to an operation of the dryer 100 to the dryer 100. For example, the user input device 110 may also include various known elements such as a remote controller configured to receive a control command from a user at a remote place and transmit the received control command to the dryer 100.
In this way, the user input device 110 may receive a control command related to the dryer 100 from the user and output an electrical signal corresponding to the received control command to the controller 180.
The display 115 may display an operational state of the dryer 100 and a control command from the user. For example, the display 115 may display a drying course selected by the user and display the time remaining until the end of drying during operation of the dryer 100.
The display 115 may be implemented using various types of known displays such as a light emitting diode (LED) panel, an organic light emitting diode (OLED) panel, or a liquid crystal display (LCD) panel. However, the display 115 is not limited thereto and may be any device capable of visually displaying various pieces of information related to the dryer 100.
The display 115 may also employ a touch screen panel (TSP) configured to receive a control command from a user and display operational information corresponding to the received control command. The TSP may include a display configured to display operational information and a control command which may be input by a user, a touch panel configured to detect coordinates of a point with which a part of the user's body has come in contact, and a touch screen controller configured to determine the control command input by the user on the basis of the coordinates of the point of contact detected by the touch panel. The touch screen controller may compare coordinates of the point of touch made by the user detected through the touch panel and coordinates of the control command displayed through the display and recognize the control command input by the user.
In this way, the display 115 may receive a control signal related to the display from the controller 180 and display an image corresponding to the received control signal.
The dryer 100 includes the drum 130 configured to accommodate an object to be dried and dry the object to be dried. The drum 130 may be rotatably installed in the cabinet 101.
The drum 130 may be formed in a cylindrical shape whose center of rotation is formed in a front-rear, horizontal direction. A front panel 131 having an opening 131a formed therein to allow an object to be dried to be put in the drum 130 may be disposed at a front surface of the drum 130. Also, a rear surface of the drum 130 may be closed by a rear panel 132 having an inlet 132a formed therein to allow introduction of high-temperature, dry air.
An outlet 131b through which air used in drying the object to be dried is discharged may be provided in the front panel 131 of the drum 130. A filter 133 configured to collect foreign substances removed from the object to be dried may be installed in the outlet 131b. Accordingly, the foreign substances removed from the object to be dried may be collected by the filter 133.
The drum 130 may receive a rotary force from a drum motor 135 and rotate. The drum 130 is connected to the drum motor 135 disposed in the cabinet 101 by a belt 136. The drum motor 135 may provide the rotary force to the drum 130 through the belt 136.
One or more heat sources may be provided in the dryer 100, and the dryer 100 may supply high-temperature air to the drum 130 through the heat sources. For example, the dryer 100 may include, as the heat sources, a heater 155 and a heat pump 160. In this case, dryers including a heat pump forming a refrigerant circuit may be classified into circulating type dryers and air discharge type dryers according to the flow of air being circulated. The circulating type dryer refers to a dryer capable of drying an object by circulating air without discharging or sucking air. The air discharge type dryer refers to a dryer which sucks outside air, uses the outside air in drying, and then discharges the outside air to the outside of the dryer.
The dryer 100 may include the fan 140 configured to circulate air inside the drum 130. The fan 140 may suck air from inside the drum 130 and discharge the air to the duct 150. By the fan 140, the air inside the drum 130 may circulate through the drum 130 and the duct 150.
The fan 140 may rotate by the fan motor 145. The fan motor 145 may rotate the fan 140 according to a control signal from the controller 180.
The heater 155 and the heat pump 160 may be provided in the duct 150 through which the air inside the drum 130 circulates.
As illustrated in
The compressor 161 may compress refrigerant in a gaseous state to a high-temperature, high-pressure state and discharge the gaseous refrigerant in the high-temperature, high-pressure state. For example, the compressor 161 may compress refrigerant through reciprocating movement of a piston or rotation of a rotor. The discharged refrigerant may be transferred to the condenser 162.
The condenser 162 may condense the compressed gaseous refrigerant to a liquid. The condenser 162 may dissipate heat to surrounding portions thereof through the process of condensing the refrigerant. The condenser 162 may be provided in the duct 150 and heat the air through heat generated in the process of condensing the refrigerant. The heated air may be supplied to the drum 130. The liquid refrigerant condensed by the condenser 162 may be transferred to the expander 163.
The expander 163 may expand the high-temperature, high-pressure liquid refrigerant condensed by the condenser 162 to liquid refrigerant in a low-pressure state. For example, the expander 163 may include an expansion valve configured to adjust a pressure difference of the refrigerant. The expansion valve may include an electronic expansion valve (EEV) whose degree of opening may vary according to an electrical signal. The dryer 100 may control a flow rate of the refrigerant by adjusting the degree of opening of the expander 163 through a control signal.
The evaporator 164 may evaporate the liquid refrigerant expanded by the expander 163. As a result, the evaporator 164 may cause the low-temperature, low-pressure gaseous refrigerant to return to the compressor 161.
The evaporator 164 may absorb heat from surrounding portions thereof through an evaporation process in which the low-pressure liquid refrigerant is changed to gaseous refrigerant. The evaporator 164 may be provided in the duct 150 and may cool air passing through the evaporator 164 in the evaporation process.
Air around the evaporator 164 may be cooled by the evaporator 164, and, when a temperature of the air around the evaporator 164 becomes lower than the dew point, the air around the evaporator 164 may be condensed. The water due to condensation at the evaporator 164 may be collected by a water trap provided at a lower portion of the evaporator 164. The water collected by the water trap may move to a separate storage or be drained to the outside of the dryer 100.
Due to the condensation occurring around the evaporator 164, the absolute humidity of air passing through the evaporator 164 may be lowered. In other words, the amount of water vapor contained in the air passing through the evaporator 164 may be reduced.
Using the condensation occurring around the evaporator 164, the dryer 100 may reduce the amount of water vapor contained in the air inside the drum 130 and dry the object to be dried.
The evaporator 164 may be disposed more upstream than the condenser 162 on the basis of the flow of air due to the fan 140. The air circulating due to the fan 140 may be dried (water vapor may be condensed) by the evaporator 164 while the air passes through the evaporator 164, and then the air may be heated by the condenser 162 while passing through the condenser 162.
The heater 166 may assist the condenser 162 in heating the air. The heater 155 may heat air in the duct 150 in response to a control signal from the controller 180. For example, before the condenser 162 of the heat pump 160 sufficiently heats the air in the duct 150, the heater 155 may assist the condenser 162 in heating the air in the duct 150.
The temperature inside the drum 130 may more rapidly rise due to the heater 155 assisting the condenser 162, and the dryer 100 may more rapidly dry the object to be dried.
The heater 155 may be disposed more downstream than the condenser 162 on the basis of the flow of air due to the fan 140. The heater 155 may be implemented through a heating coil. However, the heater 155 is not limited thereto and may be implemented through various other known devices.
As illustrated in
The opening 103a is opened or closed by a door 190 rotatably installed at the cabinet 101. Also, the drum 130 may be configured to allow an object to be dried to be put in the drum 130 or allow a dried object to be taken out of the drum 130 when the opening 103a is opened by the door 190.
The door 190 includes a door base 191 capable of opening or closing the opening 103a, a door hinge 192 configured to rotatably fix the door base 191 to one side of the cabinet 101 and a lever tip 193 provided to lock the door.
The door base 191 may cover the opening 103a of the cabinet 101. At least a portion of the door base 191 may be formed of a transparent material to allow a user to view the inside of the drum 130.
The door hinge 192 may be provided at one side of the door base 191. The door hinge 192 may rotatably fix the door base 191 to one side of the cabinet 101.
The door base 191 may rotate about the door hinge 192. The door base 191 may close or open the opening 103a of the cabinet 101 while rotating about the door hinge 192.
The door hinge 192 may be provided at one end of the door base 191 and removably installed at an outer side of the front cover 103 in the vicinity of the opening 103a of the cabinet 101.
The door hinge 192 may be installed at a left side of the opening 103a or installed at a right side of the opening 103a. The door 190 may be rotatably fixed to the left side of the opening 103a or rotatably fixed to the right side of the opening 103a, depending on a position at which the door hinge 192 is installed.
For example, the door hinge 192 may be provided at a left side end of the door base 191 and fixed to the left side of the opening 103a of the front cover 103. Thus, the door 190 may rotate about the left side of the opening 103a of the cabinet 101 and the left side end of the door base 191. In other words, the door 190 may open the opening 103a by rotating leftward and close the opening 103a by rotating rightward.
Also, the door hinge 192 may be provided at a right side end of the door base 191 and fixed to the right side of the opening 103a of the front cover 103. Thus, the door 190 may rotate about the right side of the opening 103a of the cabinet 101 and the right side end of the door 190. In other words, the door 190 may open the opening 103a by rotating rightward and close the opening 103a by rotating leftward.
The lever tip 193 may be installed at the opposite side of the door hinge 192 on the door base 191.
When the door hinge 192 is disposed at the left side end of the door base 191, the lever tip 193 may be disposed at the right side end of the door base 191 and be inserted into a hole in the right side of the opening 103a when the door 190 is closed. Also, when the door hinge 192 is disposed at the right side end of the door base 191, the lever tip 193 may be disposed at the left side end of the door base 191 and be inserted into a hole in the left side of the opening 103a when the door 190 is closed.
The lever tip 193 may be inserted into a door lock 200, which will be described below, when the door 190 closes the opening 103a.
The lever tip 193 may be fixed by the door lock 200. A hollow may be formed in the center of the lever tip 193, and the hollow of the lever tip 193 may be fixed by a catch cap which will be described below.
When the lever tip 193 is fixed by the door lock 200, the door 190 may keep the opening 103a closed and may be unable to be opened by an external force. In other words, the door 190 is locked by the door lock 200.
The door 190 may be disposed at a position at which the door 190 opens the opening 103a and a position at which the door 190 closes the opening 103a. Also, when the door 190 is disposed at the position at which the door 190 closes the opening 103a, the door 190 may be locked by the door lock 200 or unlocked by the door lock 200.
The door closure detector 170 may detect a closed state of the door 190 and an opened state of the door 190.
For example, the door closure detector 170 may include a push switch 171 disposed in the vicinity of the opening 103a of the cabinet 101. The push switch 171 may be unable to be pressed when the door 190 opens the opening 103a. Also, the push switch 171 may be pressed by the door 190 when the door 190 closes the opening 103a.
The door closure detector 170 may output a signal indicating that the door 190 is opened or a signal indicating that the door 190 is closed to the controller 180 on the basis of whether the push switch 171 is pressed. For example, the door closure detector 170 may output the signal indicating that the door 190 is opened to the controller 180 in response to the push switch 171 not being pressed. Also, the door closure detector 170 may output the signal indicating that the door 190 is closed to the controller 180 in response to the push switch 171 being pressed.
As illustrated in
The first door latch 210 and the second door latch 220 may be provided at an inner side of the front cover 103 of the cabinet 101. As illustrated in
As illustrated in
The user may fix the door hinge 192 at the left side of the opening 103a of the front cover 103 by using a screw 192a (see
When the door 190 is fixed to the left side of the opening 103a, the door hinge 192 is disposed at the left side end of the door base 191, and the lever tip 193 is disposed at the right side end of the door base 191. Thus, the door 190 is closed by rotating rightward from the left side, and the first door latch 210 provided at the right side of the opening 103a may fix the lever tip 193 of the door 190.
In this way, due to the first door latch 210 being installed at the right side of the opening 103a, the user may install the door 190 at the left side of the opening 103a of the front cover 103 without removing the front cover 103 from the cabinet 101.
As illustrated in
The user may fix the door hinge 192 to the right side of the opening 103a of the front cover 103 by using a screw (see
When the door 190 is fixed to the right side of the opening 103a, the door hinge 192 is disposed at the right side end of the door base 191, and the lever tip 193 is disposed at the left side end of the door base 191. Thus, the door 190 is closed by rotating leftward from the right side, and the second door latch 220 provided at the left side of the opening 103a may fix the lever tip 193 of the door 190.
In this way, due to the second door latch 220 being installed at the left side of the opening 103a, the user may install the door 190 at the right side of the opening 103a of the front cover 103 without removing the front cover 103 from the cabinet 101.
The first door latch 210 and the second door latch 220 may each fix the lever tip 193 of the door 190 in response to a door locking signal from the controller 180. In other words, the door lock 200 may lock the door 190 in response to the door locking signal from the controller 180.
Also, the first door latch 210 and the second door latch 220 may each lock the door 190 depending on whether the door 190 is closed. In other words, the first door latch 210 and the second door latch 220 may lock the door 190 in a state in which the door 190 is closed.
In this way, the door lock 200 may detect closure of the door 190 separately from the door closure detector 170. In other words, when the door 190 is not detected by the door closure detector 170, the door 190 is not locked, and the drying operation does not start. Also, when the door closure detector 170 detects the door 190 but closure of the door 190 is not detected by the door lock 200, the door 190 is not locked, and the drying operation does not start.
Thus, erroneous detection of the closure of the door 190 is reduced, and the drying operation is prevented from starting while the door 190 is open.
The first door latch 210 and the second door latch 220 will be described in more detail below.
The controller 180 may include a memory 182 configured to store a program and data for controlling the operation of the dryer 100 and a processor 181 configured to generate a control signal for controlling the operation of the dryer 100 according to the program and data stored in the memory 182. The memory 182 and the processor 181 may be implemented with separate chips or implemented with a single chip. Also, the controller 180 may include a plurality of memories or a plurality of processors.
The memory 182 may store a program and data for controlling the drying operation according to each drying course. For example, the memory 182 may store a speed of rotation of the drum 130 according to each drying course, a set temperature inside the drum 130 according to each drying course, and the like.
Also, the memory 182 may store a user input received through the user input device 110 or store information related to the operation of the dryer 100 (for example, the time remaining until the end of drying).
The memory 182 may include a volatile memory such as a static random access memory (S-RAM) and a dynamic random access memory (D-RAM) and a non-volatile memory such as a read-only memory (ROM), an erasable programmable read-only memory (EPROM), and an electrically erasable programmable read-only memory (EEPROM).
The memory 182 may include a single memory device or a plurality of memory devices.
The processor 181 may process data according the program provided from the memory 182 and generate a control signal on the basis of a processing result.
The processor 181 may process a user input received through the user input device 110 and an output signal of the door closure detector 170 and generate a control signal for controlling the door lock 200, the drum motor 135, the fan motor 145, the heater 155, and the heat pump 160 on the basis of a processing result.
For example, the processor 181 may output a control signal for controlling the door lock 200 to lock the door 190 to the door lock 200 in response to a user input indicating a start of an operation and a signal indicating closure of the door 190.
Also, the processor 181 may determine a drying course according to the user input. The processor 181 may determine a speed of rotation of the drum 130 according to the drying course and output a control signal corresponding to the determined speed of rotation to the drum motor 135. The processor 181 may determine a set temperature inside the drum 130 according to the drying course and output a control signal according to the determined set temperature to the heater 155 and the heat pump 160.
The processor 181 may include an arithmetic circuit, a storage circuit, and a control circuit. The processor 181 may include a single chip or include a plurality of chips. Also, the processor 181 may include a single core or include a plurality of cores.
Hereinafter, the first door latch 210 will be described. The second door latch 220 may be configured to be vertically symmetrical to the first door latch 210.
As illustrated in
Each of the first door locking terminal 211, the first neutral terminal 212, and the first locking detection terminal 213 may be connected to the controller 180.
The first closure detection switch 214 may detect whether the door 190 is closed. Specifically, the first closure detection switch 214 may detect whether the lever tip 193 disposed at the right side end of the door 190 is inserted into the first door latch 210 when the door 190 is installed at the left side of the opening 103a of the front cover 103.
The lever tip 193 of the door 190 is not inserted into the first door latch 210 while the door 190 is open. When the lever tip 193 of the door 190 is not inserted into the first door latch 210, the first closure detection switch 214 is opened (turned off).
Also, the lever tip 193 of the door 190 is inserted into the first door latch 210 when the door 190 is closed. When the lever tip 193 of the door 190 is inserted into the first door latch 210, the first closure detection switch 214 is closed (turned on).
One end of the first closure detection switch 214 is connected to the first solenoid 215. The other end of the first closure detection switch 214 may be connected to the first neutral terminal 212 and the first locking detection switch 216.
The first solenoid 215 may lock or unlock the door 190 in response to a door locking signal from the controller 180.
For example, the first solenoid 215 may generate a magnetic field in response to an electrical pulse. A first magnetic body inserted into the first solenoid 215 may perform translational movement due to the magnetic field of the first solenoid 215. The lever tip 193 of the door 190 may be fixed to the first door latch 210 due to the movement of the first magnetic body. In other words, the first solenoid 215 may convert an electrical signal to the translational movement of the first magnetic body, and the door 190 is locked due to the translational movement of the first magnetic body.
Also, the first magnetic body inserted into the first solenoid 215 interlocks with the first locking detection switch 216. Specifically, when the door 190 is locked due to the first magnetic body, simultaneously, the first magnetic body may close (turn on) the first locking detection switch 216. Also, when the door 190 is unlocked due to the first magnetic body, simultaneously, the first magnetic body may open (turn off) the first locking detection switch 216. In other words, the first solenoid 215 may open or close the first locking detection switch 216 in response to the door locking signal from the controller 180.
One end of the first solenoid 215 is connected to the first door locking terminal 211, and the other end of the first solenoid 215 is connected to the first closure detection switch 214.
Therefore, the first door locking terminal 211, the first solenoid 215, the first closure detection switch 214, and the first neutral terminal 212 may be electrically connected to each other in that order.
When the first closure detection switch 214 is closed (turned on), a circuit formed of the first door locking terminal 211, the first solenoid 215, the first closure detection switch 214, the first neutral terminal 212, and the controller 180 may be closed. Therefore, the door locking signal output from the controller 180 may drive the first solenoid 215. In other words, when the first closure detection switch 214 is closed (turned on), the controller 180 may lock the door 190 and unlock the door 190 using the first solenoid 215.
On the other hand, when the first closure detection switch 214 is opened (turned off), the circuit formed of the first door locking terminal 211, the first solenoid 215, the first closure detection switch 214, the first neutral terminal 212, and the controller 180 may be opened. Therefore, the door locking signal output from the controller 180 is not transmitted to the first solenoid 215. In other words, when the first closure detection switch 214 is opened (turned off), the controller 180 is unable to lock the door 190 using the first solenoid 215.
The first closure detection switch 214 may detect whether the door 190 is locked. Specifically, when the door 190 is installed at the left side of the opening 103a of the front cover 103, the first locking detection switch 216 may detect whether the lever tip 193 disposed at the right side end of the door 190 is fixed to the first door latch 210.
The first solenoid 215 may lock or unlock the door 190 in response to the door locking signal from the controller 180. The first solenoid 215 may simultaneously lock the door 190 and close (turn on) the first locking detection switch 216. Also, the first solenoid 215 may simultaneously unlock the door 190 and open (turn off) the first locking detection switch 216.
One end of the first locking detection switch 216 is connected to the first neutral terminal 212. The other end of the first locking detection switch 216 may be connected to the first locking detection terminal 213.
When the first locking detection switch 216 is closed (turned on), a circuit formed of the first locking detection terminal 213, the first locking detection switch 216, the first neutral terminal 212, and the controller 180 may be closed. Therefore, through the first locking detection terminal 213, the controller 180 may identify that the door 190 is locked.
On the other hand, when the first locking detection switch 216 is opened (turned off), the circuit formed of the first locking detection terminal 213, the first locking detection switch 216, the first neutral terminal 212, and the controller 180 may be opened. Therefore, through the first locking detection terminal 213, the controller 180 may identify that the door 190 is unlocked.
In this way, the first closure detection switch 214 may be closed in response to closing of the door 190. When the first closure detection switch 214 is closed, the controller 180 may drive the first solenoid 215 so that the door 190 is locked. The first locking detection switch 216 may be closed (turned on) by driving of the first solenoid 215, and, from the closure of the first locking detection switch 216, the controller 180 may identify that the door 190 is locked.
The second door latch 220 includes the same configuration as the first door latch 210. For example, the second door latch 220 may include a second door locking terminal, a second neutral terminal, a second locking terminal, a second closure detection switch, a second solenoid, and a second locking detection switch.
The elements of the second door latch 220 may be disposed to be vertically symmetrical to the elements of the first door latch 210. For example, when, in the first door latch 210, the first door locking terminal 211, the first neutral terminal 212, and the first locking detection terminal 213 are disposed in that order from left to right, in the second door latch 220, the second locking detection terminal, the second neutral terminal, and the second door locking terminal may be disposed in that order from left to right.
Referring to
A first cover 241 in which an accommodation space for accommodating the elements of the first door latch 210 is formed is provided in the first housing 231 and the second housing 232. One side of the first cover 241 may be open, and the open side surface of the first cover 241 may be sealed by a second cover 242.
The first solenoid 215, a first magnetic body 215a, the first door locking terminal 211, the first neutral terminal 212, the first locking detection terminal 213, and a switch plate 261 may be provided in the accommodation space of the first cover 241. Also, a door slider 251 and a locking slider 252 may be provided in front of the first cover 241, and a catch cap 271 may be provided at the left side of the first cover 241.
The catch cap 271 may be rotatably seated on a third cover 243 disposed at the left side of the second cover 242. The catch cap 271 may be formed substantially in the shape of alphabet “A” and include a first leg 271a and a second leg 271b.
While the door 190 is opened, the catch cap 271 may have a first posture in which a space between the first leg 271a and the second leg 271b faces the front.
When the door 190 is closed, the lever tip 193 passes through the hole 231a of the first housing 231. Also, the lever tip 193 is seated in the space between the first leg 271a and the second leg 271b. The lever tip 193 applies a pushing force to the first leg 271a, and the catch cap 271 rotates about a rotating shaft 271c.
Due to the rotation, the catch cap 271 may have a second posture in which the space between the first leg 271a and the second leg 271b faces the lower side.
When the door 190 is closed, due to the lever tip 193 passing through the hole 231a of the first housing 231, the door slider 251 may move in a first direction D1 (rightward in
Due to the movement of the door slider 251 in the first direction D1, the first closure detection switch 214 is closed (turned on).
The first closure detection switch 214 may be formed of the switch plate 261 and the one end of the first solenoid 215.
The switch plate 261 electrically comes in contact with the first neutral terminal 212. Also, the switch plate 261 may be formed substantially in the shape of alphabet “V” and include a first contact plate 261a and a second contact plate 261b.
While the door 190 is opened, the first contact plate 261a is spaced apart from the one end of the first solenoid 215 due to the door slider 251. In other words, the first closure detection switch 214 is opened (turned off).
When the door 190 is closed, as the door slider 251 moves in the first direction D1, the first contact plate 261a comes in contact with the one end of the first solenoid 215. In other words, the first closure detection switch 214 is closed (turned on).
The first solenoid 215 and the first magnetic body 215a may be provided in the accommodation space of the first cover 241. The one end of the first solenoid 215 forms the first closure detection switch 214 together with the first contact plate 261a. The other end of the first solenoid 215 may be electrically connected to the first door locking terminal 211.
The first magnetic body 215a may be movably inserted into the first solenoid 215. When electricity is supplied to the first solenoid 215, the first solenoid 215 may generate a magnetic field, and the first magnetic body 215a may perform translational movement due to the magnetic field of the first solenoid 215.
The controller 180 may output a door locking signal in order to lock the door 190. The first solenoid 215 may lock the door 190 in response to the door locking signal from the controller 180. When the first solenoid 215 generates a magnetic field due to the electrical signal (door locking signal) supplied from the controller 180, the first magnetic body 215a may move upward due to the magnetic field of the first solenoid 215.
The movement of the first magnetic body 215a may be transferred to the locking slider 252 via mechanical devices included in the first door latch 210, and the locking slider 252 may move in a third direction D3 (toward the lower left side in
Due to the movement of the locking slider 252 in the third direction D3, rotation of the catch cap 271 is restricted as illustrated in
Also, due to the movement of the locking slider 252 in the third direction D3, the first locking detection switch 216 is closed (turned on).
The first locking detection switch 216 may be formed of the switch plate 261 and the first locking detection terminal 213.
As described above, the switch plate 261 may include the first contact plate 261a and the second contact plate 261b.
While the door 190 is unlocked, the second contact plate 261b is spaced apart from the first locking detection terminal 213 due to the locking slider 252. In other words, the first locking detection switch 216 is opened (turned off).
While the door 190 is locked, as the locking slider 252 moves in the third direction D3, the second contact plate 261b comes in contact with the first locking detection terminal 213. In other words, the first locking detection switch 216 is closed (turned on).
On the basis of the opening of the first locking detection switch 216, the controller 180 may identify that the door 190 is unlocked. On the basis of the closing of the first locking detection switch 216, the controller 180 may identify that the door 190 is locked.
The controller 180 may output a door unlocking signal in order to unlock the door 190. The first solenoid 215 may unlock the door 190 in response to the door unlocking signal from the controller 180. When the first solenoid 215 generates a magnetic field due to the electrical signal (door unlocking signal) supplied from the controller 180, the first magnetic body 215a may move upward again due to the magnetic field of the first solenoid 215.
The movement of the first magnetic body 215a may be transferred to the locking slider 252 via the mechanical devices included in the first door latch 210, and the locking slider 252 may move in a fourth direction D4 (toward the upper right side in
Due to the movement of the locking slider 252 in the fourth direction D4, the rotation of the catch cap 271 is permitted. Since the rotation of the catch cap 271 is possible, the lever tip 193 is released from the first door latch 210. In other words, the door 190 is unlocked.
Also, due to the movement of the locking slider 252 in the fourth direction D4, the second contact plate 261b is spaced apart from the first locking detection terminal 213. In other words, the first locking detection switch 216 is opened (turned off).
When the door 190 is opened, the door slider 251 may move in a second direction D2 (leftward in
Due to the movement of the door slider 251 in the second direction D2, the first contact plate 261a is spaced apart from the one end of the first solenoid 215. In other words, the first closure detection switch 214 is opened (turned off).
In this way, the first door latch 210 may include the door slider 251 which moves due to the lever tip 193, and, due to the movement of the door slider 251, the first closure detection switch 214 may be closed (turned on) or opened (turned off).
Also, the first door latch 210 includes the locking slider 252 which moves due to the operation of the first solenoid 215, and, due to the movement of the locking slider 252, the door 190 is locked or unlocked. Also, due to the movement of the locking slider 252, the first locking detection switch 216 may be closed (turned on) or opened (turned off).
The second door latch 220 includes the same configuration as the first door latch 210. For example, the second door latch 220 may include a second solenoid, a door slider, a locking slider, and a switch plate.
The elements of the second door latch 220 may be disposed to be vertically symmetrical to the elements of the first door latch 210. Also, the elements of the second door latch 220 may move in a manner vertically symmetrical to the elements of the first door latch 210.
As illustrated in
The first door locking terminal 211, the first neutral terminal 212, and the first locking detection terminal 213, which are connected to the controller 180, are provided in the first door latch 210.
The first door latch 210 includes the first closure detection switch 214 configured to detect closure of the door 190, the first solenoid 215 configured to generate a dynamic force for locking the door 190, and the first locking detection switch 216 configured to detect locking of the door 190.
A second door locking terminal 221, a second neutral terminal 222, and a second locking detection terminal 223, which are connected to the controller 180, are provided in the second door latch 220.
The second door latch 220 includes a second closure detection switch 224, a second solenoid 225, and a second locking detection switch 226. The configurations and functions of the second closure detection switch 224, the second solenoid 225, and the second locking detection switch 226 are the same as those of the first closure detection switch 214, the first solenoid 215, and the first locking detection switch 216.
As illustrated in
The first door latch 210 and the second door latch 220 may be connected in parallel with the controller 180. The first door locking terminal 211 may be connected to the controller 180 together with the second door locking terminal 221, and the first neutral terminal 212 may be connected to the controller 180 together with the second neutral terminal 222. Also, the first locking detection terminal 213 may be connected to the controller 180 together with the second locking detection terminal 223.
Thus, the first closure detection switch 214 and the first solenoid 215 are connected in parallel with the second closure detection switch 224 and the second solenoid 225. Also, the first locking detection switch 216 is connected in parallel with the second locking detection switch 226.
The controller 180 may output a door locking signal, and the door locking signal of the controller 180 may be input to the first door latch 210 through the first door locking terminal 211 and be input to the second door latch 220 through the second door locking terminal 221. Since the first door latch 210 and the second door latch 220 are connected in parallel with the controller 180, a signal output from the controller 180 may be input to both the first door latch 210 and the second door latch 220.
The first solenoid 215 may be driven by the door locking signal depending on whether the first closure detection switch 214 is closed (turned on), and the second solenoid 225 may be driven by the door locking signal depending on whether the second closure detection switch 224 is closed (turned on).
The controller 180 may identify that the door 190 is locked, on the basis of the first locking detection switch 216 and the second locking detection switch 226 being closed (turned on). Since the first locking detection switch 216 and the second locking detection switch 226 are connected in parallel with each other, the controller 180 may identify that the door 190 is locked when any one of the first locking detection switch 216 and the second locking detection switch 226 is closed (turned on).
For example, the door hinge 192 may be disposed at the left side of the opening 103a of the front cover 103, and the lever tip 193 may be disposed at the right side end of the door 190. When the door 190 is closed, as illustrated in
As illustrated in
On the other hand, since the second closure detection switch 224 is in the open (off) state, the door locking signal is not input to the second solenoid 225. The second solenoid 225 is not driven, and the second locking detection switch 226 may maintain being opened (turned off).
On the basis of the first locking detection switch 216 being closed (turned on), the controller 180 may identify that the door 190 is locked.
Also, the door hinge 192 may be disposed at the right side of the opening 103a of the front cover 103, and the lever tip 193 may be disposed at the left side end of the door 190. When the door 190 is closed, as illustrated in
As illustrated in
On the other hand, since the first closure detection switch 214 is in the open (off) state, the door locking signal is not input to the first solenoid 215. The first solenoid 215 is not driven, and the first locking detection switch 216 may maintain being opened (turned off).
On the basis of the second locking detection switch 226 being closed (turned on), the controller 180 may identify that the door 190 is locked.
As illustrated in
The first door locking terminal 211, the first neutral terminal 212, and the first locking detection terminal 213 are provided in the first door latch 210, and the first door latch 210 includes the first closure detection switch 214, the first solenoid 215, and the first locking detection switch 216.
The second door locking terminal 221, the second neutral terminal 222, and the second locking detection terminal 223 are provided in the second door latch 220, and the second door latch 220 includes the second closure detection switch 224, the second solenoid 225, and the second locking detection switch 226.
As illustrated in
The first door latch 210 and the second door latch 220 may be connected in series with the controller 180. The first door locking terminal 211 is connected to the controller 180, the first locking detection terminal 213 is connected to the second door locking terminal 221, and the second locking detection terminal 223 is connected to the controller 180. Also, the first neutral terminal 212 may be connected to the controller 180 together with the second neutral terminal 222.
Thus, the first solenoid 215, the first closure detection switch 214, the first locking detection switch 216, the second solenoid 225, the second closure detection switch 224, and the second locking detection switch 226 are connected in series with each other.
The controller 180 may output a door locking signal, and the door locking signal of the controller 180 may be sequentially input to the first door latch 210 and the second door latch 220.
When both the first closure detection switch 214 and the second closure detection switch 224 are closed (turned on), the first solenoid 215 and the second solenoid 225 may be sequentially driven.
On the basis of the first locking detection switch 216 and the second locking detection switch 226 being closed (turned on), the controller 180 may identify that the door 190 is locked. Since the first locking detection switch 216 and the second locking detection switch 226 are connected in series with each other, the controller 180 may identify that the door 190 is locked when both the first locking detection switch 216 and the second locking detection switch 226 are closed (turned on).
For example, the door hinge 192 may be disposed at the left side of the opening 103a of the front cover 103, and the lever tip 193 may be disposed at the right side end of the door 190. When the door 190 is closed, as illustrated in
Since the first door latch 210 and the second door latch 220 are connected in series with each other, the first solenoid 215 and the second solenoid 225 are either driven or not driven, depending on whether the first closure detection switch 214 is closed (turned on) or opened (turned off). When the first closure detection switch 214 is in a closed (on) state, the first solenoid 215 is driven by a primary door locking signal from the controller 180, and the second solenoid 225 is driven by a secondary door locking signal from the controller 180. When the first closure detection switch 214 is in an opened (off) state, the first solenoid 215 and the second solenoid 225 are not driven.
As illustrated in
Each of the first door latch 210 and the second door latch 220 may be connected to the controller 180. The controller 180 may control the first door latch 210 and the second door latch 220 independently of each other. For example, the controller 180 may output a first door locking signal to the first door latch 210 and output a second door locking signal to the second door latch 220.
Also, from each of the first door latch 210 and the second door latch 220, the controller 180 may identify whether the door 190 is locked.
An operation 1000 of a dryer 100 will be described with reference to
The dryer 100 receives a user input (1010).
A controller 180 may receive the user input through a user input device 110. For example, the user may select a drying course and input an operational command through the user input device 110.
The dryer 100 determines whether a door 190 is closed (1020).
When the user selects a drying course and inputs an operational command, before starting the operation, the controller 180 may determine whether the door 190 is closed. For example, the controller 180 may identify whether the door 190 is closed on the basis of whether closure of the door 190 is detected by the door closure detector 170.
When the closure of the door 190 is not detected (NO in 1020), the dryer 100 warns of the opening of the door 190 (1025).
In response to not receiving a door closure signal from the door closure detector 170, the controller 180 may display a message indicating opening of the door 190 on the display 115.
When the closure of the door 190 is detected (YES in 1020), the dryer 100 locks the door 190 (1030).
A first door latch 210 and a second door latch 220 may be connected in parallel with the controller 180, or the first door latch 210 and the second door latch 220 may be connected in series with the controller 180. Alternatively, the first door latch 210 and the second door latch 220 may be separately connected to the controller 180.
The controller 180 may output a door locking signal for locking the door 190 to the first door latch 210 and the second door latch 220.
The dryer 100 determines whether the door 190 is locked (1040).
Each of the first door latch 210 and the second door latch 220 which received the door locking signal from the controller 180 may lock the door 190 depending on whether the door 190 is closed and output the door locking signal depending on whether the door 190 is locked. The controller 180 may identify whether the door 190 is locked on the basis of whether the door locking signal is received.
When locking of the door 190 is not detected (NO in 1040), the dryer 100 warns of the opening of the door 190 (1045).
In response to not receiving a door locking signal from the door lock 200, the controller 180 may display a message indicating the opening of the door 190 on the display 115.
When the locking of the door 190 is detected (YES in 1020), the dryer 100 performs a drying operation (1050).
The controller 180 may control the drum motor 135 to rotate the drum 130 and control the fan motor 145 to rotate the fan 140. The controller 180 may control the heat pump 160 to condense water vapor from air inside the drum 130 and control the heater 155 to heat the air inside the drum 130.
