Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a clothes dryer 1 according to the present invention, in which the clothes dryer 1 has a clothes dryer main body 2 and an inner space having an internal space capable of completely drying wet laundry (not shown). It is composed of a door (4) which is connected to one side wall of the door by a hinge (not shown) and openable as a handle (3). 1, far-infrared generating means 5 for radiating far-infrared rays into the main body is provided at the lower side of the inner space, that is, the lower part of the main body 2. As shown in FIG. 2, the lower part of the far-infrared generating means 5 is disposed slightly apart from the base 6 of the main body 2 to forcibly introduce hot hot air into the main body 2 during far-infrared generation. The hot air generating means 7 for inflow is mounted.

2 is a side cross-sectional view of the clothes dryer 1 seen along the line II-II shown in FIG. 1, wherein the far-infrared ray generating means 5 includes a heater coil 8 for generating a predetermined heat, and this heater. A longitudinal support 9 supporting the coil 8 and a far infrared radiation plate 10 which can cover (close) the heater coil 8 are included. Here, the surface of the far-infrared radiation plate 10 is coated with a bio-ceramic material 10A so that when the heater coil 8 is heated, the far-infrared rays of the main body 2 are formed through a plurality of holes 12 formed in the cover 11. Radiate into the interior space. By the way, the far-infrared heater coil 8 is mounted on the upper side of the vertical support 9, but the heater coil 13 is inserted in the lower part of the vertical support 9 to generate heat for drying the wet laundry. Here, each vertical support 9 is formed with a plurality of holes 13a (see FIG. 3) into which the upper coil 8 and the lower heater coil 13 can be inserted. The lower heater coil 13 is for warming the outside air. And, each vertical support 9 is inserted and fixed to the horizontal support 14, the vertical support 9 and the horizontal support 14 is composed of a mica plate having a thickness of about 1mm.

On the other hand, the hot air generating means 7 includes a blowing fan 15 including a blowing motor for sucking the outside air and blowing it toward the heater coil 13. On the outside of the blower fan 15, a filter 16 for purifying external air is provided. The blowing fan 15 is fixed to the rectangular frame 17 formed behind the lower part of the main body 2 by the screw which is not shown in figure. In addition, the rectangular frame 17 has a shape that becomes narrower toward the inside of the main body 2 so that the air sucked by the blower fan 15 is easily blown through the central passage 18. Therefore, the air warmed while passing through the heater coil 13 can be introduced into the main body 2 through the front passage 19 provided at the front end of the central passage 18. As can be seen in detail in FIG. 2, the mica plate and the far-infrared radiating plate 10 forming the horizontal support 14 may be formed by a plurality of screws 20. It is firmly fixed to the entrance of 19).

Here, the front passageway 19 has end portions 19A and 19B contacting the right side wall 2A and the left side wall 2B of the main body 2, as shown in detail in FIG. 19A and 19B are formed to form passages that become narrower toward the upper side. Therefore, when the fan motor 15 operates, the hot air warmed by the heater coil 13 passes the right duct 21 and the left duct 22 from the central passage 18 through both front passageways 19A and 19B. Can be blown toward.

Referring to FIG. 2 again, in the duct 21 forming the right inner wall of the main body 2, hot air forcibly blown into the duct 21 by the blower fan 15 is discharged into the main body 2. First through holes 24 are formed in a plurality of through holes 23 in a row. On the other hand, as shown in FIG. 1, in the duct 22 which forms the left inner wall of the main body 2, the hot air forcibly blown into the duct 22 by the blower fan 15 inside the main body 2 is carried out. A second through-hole 26 is formed in which a plurality of through-holes 25 for flowing in the furnace are arranged in a line. Two through-holes 24 and 26 are formed in the present invention, but the present invention is not limited thereto, but may be a plurality.

As can be clearly seen in FIG. 1, the first through-hole 24 and the second through-hole 26 are installed to intersect with each other, which naturally shakes the laundry on which the moisture-sensing clothes hanger 27 hangs. It is for. In other words, the plurality of through-holes 23 in the first through-holes 24 collide with each other and the air that has escaped through the plurality of through-holes 25 in the second through-holes 26 to act as a propeller. Will be. Therefore, the laundry hanging on the clothes hanger 27 is dried in a natural drying manner. In addition, the outlet 28 serves to discharge the air to the outside so that the high-temperature air exiting the plurality of through holes 23 and 25 in the through holes 24 and 26 rapidly evaporates the moisture of the wet laundry. .

The clothes hanger 27 shown in FIG. 1 has a metallic frame 29 having a size that can be inserted into the clothes dryer body 2, and a plurality of parts for forgetting one end and the other end of the frame 29. It consists of a cross beam 30. Here, the outer side of the frame 29 has a plurality of electrode pieces (not shown) in contact with the metallic electrodes 33 and 34 of the insertion grooves 31 and 32 formed in the inner side walls 21 and 22 of the main body 2. Formed. Meanwhile, as shown in FIG. 4, hollow first to fourth metallic conductors 37A to 37D having holes 36 through which fine wires 35A and 35B can be inserted, as shown in FIG. 4. And hollow insulators 38A, 38B, 38C that electrically insulate between each adjacent conductor. In FIG. 4, the wire 35A allows the first metallic conductor 37A and the third metallic conductor 37C to be electrically connected, and the wire 35B is the second metallic conductor 37B and the fourth metallic conductor. It serves to electrically connect the 37D.

For example, assuming that the metallic conductors 37A and 37C are for the positive electrode, and the metallic conductors 37B and 37D are connected to the negative terminal, if the wet laundry is between the metallic conductors 37A and 37B. When the conductor 37A and the conductor 37B are electrically connected to each other, the conductors 37D may be connected to the conductor 37B by the wire 35B. As will be described later, the clothes dryer 1 may be operated to recognize that the currently hanging laundry is wet laundry and to dry it.

On the other hand, the garment hanger can be used by arbitrarily adjusting the interval of the cross beam 30 by the user. Therefore, the clothing hanger 27 can be arbitrarily adjusted to hang the female lingerie, bath towels for men, sanitary towels, baby clothing, and the like. And, the storage rack (39) installed in the door (4) also has the same configuration as the clothes hanger 27, which can temporarily store more clothes by using the clothes hanger 40 mounted in the middle compartment. In the shape of a triangle, for example, socks, panties, bras, etc. can be stored.

Again, referring to FIG. 2, the upper and lower heater coils 8 and 13 are provided with bimetals 41 and 42 and temperature fuses 43 and 44 for preventing excess, and the lower heater coil 13 is provided. In the fan motor 15, the demister 24 for operating the fan is installed. In FIG. 1, reference numeral SW1 denotes a power switch for supplying operating power for all devices and circuits of the clothes dryer 1, and SW2 denotes about 10 (volumes to be dried) inside the main body 2. It is a switch that acts to force operation for a minute. When moisture is detected, the switch is operated until it is dried regardless of time. The switch (SW3) is operated for about 1 minute when the laundry is dried. A switch for sterilizing is a switch that is operated for a predetermined time when pressed manually, and the switch SW4 displays a switch for turning off the device and displays a switch SW5 door switch.

Thus, the operation | movement of the clothes dryer 1 which concerns on this invention comprised is demonstrated schematically.

First, hang the dry goods on the clothes hanger (27) or the middle compartment clothes hanger, close the door (4), press the power switch (SW1), press the start switch (SW2), the upper heater coil (8) and the lower heater coil I warm the air around (13). When the temperature of the heater coil 13 rises, the temperature sensor 45 senses the temperature, and the blower fan 15 is operated. Accordingly, external air is sucked through the inlet air purification filter 16. The air heated by the heater coil 13 is circulated into the clothes dryer main body 2 through the ducts 21 and 22 along the passages 18, 19, 19A, and 19B by the blowing fan 15. At this time, the far-infrared radiation plate 10 applied by the heater coil 8 emits a large amount of far-infrared rays, penetrates into the dry matter, flows molecules of moisture, and exerts a large amount of sunlight. 22) The hot wind emitted through the water evaporation to the outlet 28 causes the drying of the dry matter within the shortest time, and after the drying is completely dried, the ultraviolet sterilization lamp 46 operates to sterilize various germs. In addition, far-infrared rays emitted so far are introduced into the building to improve the texture of the building and increase durability. At this time, the bimetals 41 and 42 and the temperature fuses 43 and 44 operate to prevent excessive overheating, and the humidity sensing members 37A to 37D on the cross beams 30 of the clothes hanger 27 sense moisture and dry them. Automatic control of the condition leads to complete drying of the dry matter. UV sterilization lamp (46) is operated in the completely dried state is expected to be excellent sterilization effect, if you want only sterilization just press the sterilization switch (SW3) only sterilization lamp (46) is operated to sterilize the internal material do. On the other hand, when the clothes dryer 1 is operated, when the door 4 is opened, the door safety off switch SW5 is activated and the interior light 47 enters, and at the same time, the control device 48 installed in the lower part of FIG. All power is cut off to ensure the safety of users.

5 is a detailed circuit diagram of the control device 48 for operating the clothes dryer of the present invention, the present invention will be described in more detail with reference to this.

First, the AC input power supply 220V or 100V is applied to the primary side wire of the transformer 51 via the power supply voltage switching switch 50, and is stepped down to a predetermined voltage on the secondary side thereof and then via the bridge circuit 52. After the smoothing is performed by the smoothing capacitor 53, it is applied to the constant voltage IC 54 and converted into a DC constant voltage for operating the circuit of FIG. If the door 4 of the clothes dryer 1 is closed, the door off switch SW5 is located at the contact point A-A 'to supply power (+ Vcc) to the timer ICs 55, 56 and 57, and the door When (4) is open, the off switch SW5 is located at the contact point B-B 'to turn on the indoor light 47.

In the state in which the door 4 is closed, the power is charged to the capacitors 61 to 63 via the resistors 58 to 60 connected to the timers 55 to 57, and the user switches the main power switch SW1. ) And the off switch SW4 are not pressed, a high power supply (+ Vcc) is applied to one input terminal of the NAND gates 66 and 67 via the resistors 64 and 65. In this case, the NAND gate 66 outputs a low state signal, and since the low output of the NAND gate 66 is applied to the other input terminal of the NAND gate 67, the NAND gate 67 outputs a high signal. It feeds back to the other input terminal of (66). Therefore, since both input terminals of the NAND gate 66 are high, the output of the NAND gate 66 is kept low. Since the NAND gate 66 is kept low, a bias in the low state is applied to the bias resistor 68 so that the transistor 69 cannot be turned on. When the transistor 69 is in the off state, the transistor 70 is also in the off state, so the potential of the P-point (+ Vcc) is connected to the ground terminal GND of each timer IC 55, 56, 57 through the resistor 71. The timer IC 55 is not operated at all because it is applied to.

However, when the user turns on the main power switch SW1, the power supply (+ Vcc) via the resistor 64 is grounded through the switch SW1, so that one input terminal of the NAND gate 66 is changed from high to low. The output of the NAND gate 66 changes from low to high to turn on the transistor 69 via the resistor 68. Transistor 69 is turned on and transistor 70 is also turned on. In this case, the P-point power supply (+ Vcc) through resistor 71 is bypassed through the collector-emitter of transistor 70. The terminals GND of the ICs 55 to 57 are grounded so that the timer ICs are enabled.

If the wet clothes are caught on the moisture-sensing clothes hanger 27 in the main body 2 of the clothes dryer 1, and the electrodes 30 are formed by the cross beams 30, the timer IC 55 Since the clock signal is generated at the output terminal Q1 of the timer IC 55, a high state signal is output. The signal output from the output terminal Q1 of the timer IV 55 turns on the transistor 73 via the resistor 72. In this case, a current flows through the relay coil 74. In this case, the coil 74 By the electromagnetic force of the relay switch 74 At contacts It is switched to a contact point and power is applied to the heater coil 13 for drying and the heater coil 8 for far-infrared radiation, and these heater coils operate.

When the heater coils 8 and 13 operate to detect the heat of the thermistor 45 installed near the heater coil 13, the base potential of the transistor 75 gradually decreases. Because the base power supply (VB) of the transistor 75 = This is because R45 is the resistance value of the thermistor 45, R76 is the resistance value of the resistor 76, and the resistance value R45 decreases as the temperature of the heater 13 increases. Gradually turns on. In other words, when the heater coil 13 operates and the temperature rises after a predetermined time has elapsed, the transistor 75 is turned on. Accordingly, the transistor 78 is also turned on through the bias resistor 77 so that the relay coil 79 is turned on. The relay switch 80 is switched from the A-contact point to the B-contact point by the electromagnetic force caused by the electric current flowing in the blower fan 45 to start operation. When the blower fan 15 operates, the outside air flows into the lower coil 13 and warms up, and then flows into the ducts 21 and 22 via the passages 18, 19, 19A, and 19B, and a plurality of through holes. By entering the inside of the main body 2 through the 23 and 25, the wet laundry is dried as described above.

When the laundry is completely dried and the electrode (+.-) By the cross beam 30 in the clothes hanger 27 is turned off, the output of the timer IC 55 is lost, but the clock pulse is caused by the capacitor 81 and the resistor 82. Is provided to timer IC 56, so that timer IC 56 continues to generate output Q2. In this case, it is possible to identify that the far-infrared heater coil 8 continues to operate and the light emitting diode LED2 inside the switch SW2 operates to exert the same effect as the start switch SW2 is pressed.

After the output Q2 of the timer IC 56 is finished, since the control voltage signal is not applied to the resistor 83, the transistor 84 is turned off, so that no current flows in the relay coil 85, so that the relay switch ( 74 is located at the A-contact so that the operation of the heater coils 8, 13 is stopped. However, even when the operation of the heater coils 8 and 13 is stopped, the temperature of the heater coils 8 and 13 detected by the thermistor 45 is maintained to some extent, so that the blower fan 8 may be turned off even when the heater coils 8 and 13 are turned off. 15) is operated for a predetermined time (i.e. during a time when the temperature of the heater coil is lowered) to completely dry the laundry.

After the timer output 56 is completed, the timer IC 57 is operated for about 1 minute by the capacitor 86 and the resistor 87 so that power is applied to the light emitting diode LED2 and the resistor 88 so that the light emitting diode LED2 ) And transistor 89 are turned on. When the transistor 89 is turned on, a current flows in the relay coil 90 so that the relay switch 91 is positioned at the B-contact point, and the ultraviolet germicidal lamp 46 operates for 1 minute to completely sterilize the laundry. After one minute of ultraviolet sterilization, the circuits shown in FIG. 5 are reset to their initial state.

On the other hand, press the main power switch (SW1) to operate the light emitting diode (LED1) and then press the stop switch (SW4) while the laundry is drying, the power supply (+ Vcc) via the resistor (63) turns the switch (SW4) Since the output of the NAND gate 67 becomes high because it is bypassed to the ground, in this case, the high output of the NAND gate 67 is applied to the other input terminal of the NAND gate 66, and one side of the NAND gate 66 is provided. Since the input of the high state by the resistor 64 is applied to the input terminal, the output of the NAND gate 66 becomes the low state so that the transistor 69 is turned off and the transistor 69 is also turned off accordingly. The operation of 57) is turned off to stop the operation of the control circuit of FIG.

If the start switch SW2 is manually operated, the timer IC 56 may forcibly operate the heater coils 8 and 13 and the blower fan 15 for about 10 minutes, and the switch SW3 is manually operated. When operating, only sterilization may be performed, and thus the detailed description thereof will be omitted since it is the same as described above.

As described above, the clothes dryer according to the present invention simply presses the power switch and hangs the wet laundry on the clothes hanger and closes the door. The clothes are dried and sterilized at a low temperature by far infrared rays and as a natural drying method by the clothes hanger. There is no entanglement of clothing, no damage and wrinkle of clothing, no need to select the type of cloth, and it has the effect of reducing power consumption by low temperature drying method.

Although the present invention has been described based on the accompanying drawings, the present invention is not limited thereto, and many changes and modifications may be made within the scope of the following claims. For example, the clothes dryer installed in FIG. 1 may have a cylindrical or other shape instead of a rectangular parallelepiped.
