  Embodiments of the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a front view showing an external configuration of a washing / drying machine 1 according to an embodiment of the present invention. FIG. 2 is a vertical cross-sectional view of the washing / drying machine 1 and shows a cross-section viewed from the right side when cut along a vertical plane along the front-rear direction. FIG. 3 is a rear view of the washing / drying machine 1 and a part of the rear surface of the housing 2 is omitted.

  With reference to FIGS. 1 to 3, the outside of the washing / drying machine 1 is partitioned by a substantially rectangular housing 2 in a plan view, for example. The front side of the top surface of the housing 2 is formed one step lower, and is an inclined surface 2B that is inclined so as to become lower toward the front side. An opening 4 that can be opened and closed by the outer lid 3 is formed from the front end to the rear end of the inclined surface 2B at the center in the left-right direction of the inclined surface 2B.

  For example, the rear end of the outer lid 3 is rotatably attached to the housing 2, and the outer lid 3 is attached to the housing 2 by grasping and lifting the grip portion 3 </ b> C formed at the front end. The opening 4 can be opened in a state of rising upward from the inclined surface 2B along the step surface 2A. At the front upper end of the housing 2, for example, a door lock 3 </ b> A for locking the outer lid 3 so as not to be opened from the closed state at a position on the right front side of the opening 4, and opening / closing of the outer lid 3 are detected. The door switch 3B for this is arrange | positioned.

  On the right side of the opening 4 of the inclined surface 2B, for example, an operation display panel 5 for performing various settings (course setting, etc.) relating to the operation of the washing / drying machine 1 and various displays such as driving conditions is arranged ( (See FIG. 1). The operation display panel 5 faces the diagonally upper front side by being arranged on the inclined surface 2B, and the user standing on the near side of the washing / drying machine 1 faces the lower surface of the operation display panel 5 diagonally downward. Can be looked down vertically. As a result, the user can easily see and operate the display on the operation display panel 5.

  The washing / drying machine 1 is a business coin laundry machine installed in a coin laundry, for example, and executes laundry operations such as washing and drying based on the input of money. At the right end portion of the step surface 2A, for example, a money insertion slot 6A for inserting coins (for example, coins such as 100 yen and 500 yen) is formed, and the user desires from this money insertion slot 6A. The driving course can be executed by inserting money corresponding to the driving course. Whether or not the money inserted from the money insertion slot 6A is genuine money, and if it is genuine money, which kind of money (100 yen, 500 yen, etc.) is It is discriminated by the currency discriminating device 6 (see FIG. 5) provided in the washing / drying machine 1.

  For example, a return lever 6B is disposed below the money insertion slot 6A. When the user operates the return lever 6B, or when the money inserted from the money insertion slot 6A is not a genuine money, the money inserted from the money insertion slot 6A is arranged below the return lever 6B. It is returned from the money return slot 6C.

  The money inserted from the money insertion slot 6A is accommodated in, for example, a money storage box 6D. For example, a key hole is formed in the front surface of the money storage box 6D. By inserting a dedicated key into the key hole and rotating in a predetermined direction, the lock of the money storage box 6D is released, and the front side It can be made to be drawable. And the money accommodated in the said money storage box 6D can be taken out now by pulling out the money storage box 6D to the near side.

  Inside the housing 2, for example, a substantially cylindrical outer tub 7 whose both end faces are closed is arranged such that its axis extends to the left and right (substantially horizontal). The outer tub 7 is supported, for example, by a pair of dampers 8 on the front side and the rear side of the lower part of the outer peripheral surface.

  Inside the outer tub 7, a drum 10 for storing laundry therein is arranged. The drum 10 has, for example, a substantially cylindrical shape with both end surfaces closed, and is arranged such that its axis extends to the left and right (substantially horizontal). Rotating shafts 11 extending along the axis are respectively attached to both end surfaces of the drum 10, and each rotating shaft 11 is rotatably attached to both end surfaces of the outer tub 7.

  At the upper end of the outer peripheral surface of the outer tub 7, an inner lid 24 is attached at a position facing the opening 4 of the housing 2, and by rotating the inner lid 24 around its rear end, The opening of the outer tub 7 that is opened and closed by the inner lid 24 can be opened. In addition, a drum lid (not shown) is attached to the peripheral surface of the drum 10, and opening the drum opened and closed by the drum lid can be opened by opening the drum lid. ing. Therefore, in the washing / drying machine 1, the laundry can be taken in and out of the drum 10 with all of the outer lid 3, the inner lid 24 and the drum lid opened.

  For example, a DD motor 13 is connected to one (left side) rotating shaft 11 by a so-called DD system (direct drive system) (see FIG. 5). At the time of washing or drying, the drum 10 is rotated by rotating the DD motor 13 while the laundry is accommodated in the drum 10. Thereby, the operation (tumbling) in which the laundry in the drum 10 is lifted by a baffle (not shown) provided on the inner peripheral surface of the drum 10 and naturally falls from a certain height is repeated. It has become.

  On the upper left side of the rear surface of the housing 2, for example, a water supply port 15A for introducing normal temperature tap water into the machine from an external water tap or the like, and hot water supply for introducing hot water into the machine from an external hot water supply facility or the like A mouth 15B is provided (see FIG. 3). During washing, by opening the water supply valve 14A (see FIG. 5), room temperature tap water introduced into the machine from the water supply port 15A can be supplied into the outer tub 7, while the hot water supply valve 14B (see FIG. 5). By opening the, the hot water introduced into the machine from the hot water supply port 15B can be supplied into the outer tub 7.

  For example, a drain port 16 is formed at the lower end of the peripheral surface of the outer tub 7, and a drain pipe 17 is connected to the drain port 16. A drainage valve 18 is provided in the middle of the drainage pipe 17. By supplying water with the drainage valve 18 closed, normal temperature tap water or hot water (hereinafter simply referred to as “ Water)). Further, the water stored in the outer tub 7 can be drained outside the machine through the drain port 16 and the drain pipe 17 by opening the drain valve 18.

  A branch pipe 19 is connected to the drain pipe 17 on the upstream side (drain port 16 side) of the drain valve 18. The branch pipe 19 extends, for example, toward the upper front side. When water is supplied with the drain valve 18 closed, water is stored in the outer tub 7 and water is also introduced into the branch pipe 19. The branch pipe 19 communicates with, for example, an air trap (not shown), and detects a water level in the outer tub 7 by detecting a pressure change in the air trap with a water level sensor 29 (see FIG. 5). Can be done.

  A backflow prevention member 20 for preventing the drainage from the outer tub 7 from flowing backward is attached to the end of the drainage pipe 17. The backflow prevention member 20 is disposed, for example, at the lower right rear portion in the housing 2 and is connected to a drain hose for guiding water discharged from the outer tub 7 to a predetermined position outside the machine at the rear end. The drainage hose connection port 20A is formed.

  A large number of water passage holes (not shown) are formed on the peripheral surface of the drum 10, and the water supplied into the outer tub 7 flows into the drum 10 through these water passage holes. It is like that. In the washing process, which is the first step of washing, tumbling is repeated in a state where water is stored in the outer tub 7 to a predetermined water level, so that the laundry is struck against the water surface stored in the outer tub 7. Dashing is being achieved.

  When the washing process ends, a rinsing process for removing detergent components contained in the laundry is performed, and then the process proceeds to a dehydration process. In the dehydration step, the drum 10 is rotated at a high speed (for example, 300 to 1000 rpm), the water contained in the laundry is squeezed out by centrifugal force, and the moisture that comes out of the laundry passes through the water passage hole and passes through the outer tub 7. Splash to the side.

An electrolytic device 22 (see FIG. 5) for electrolyzing water in the outer tub 7 is attached to the peripheral surface of the outer tub 7, for example, on the front side of the lower portion thereof. The electrolyzer 22 includes a plurality of electrode plates (not shown) therein, and when water is taken into the electrolyzer 22 with the electrode plates energized, water and chlorine, which are components of tap water, Reacts chemically to generate active oxygen (O ₂ ⁻ ), hypochlorous acid (HClO), and the like. If washing is performed using water (electrolyzed water) after electrolytic treatment in which these products are generated, dirt from the laundry can be prevented from adhering to the laundry again, and sterilization effect can be applied to the laundry. It can be sterilized.

  On the upper right side of the rear surface of the housing 2, for example, a detergent inlet 25 A for introducing a liquid detergent into the machine from an external detergent tank, and a liquid softener (so-called softer) from an external softer tank. ) Is provided in the machine (see FIG. 3). During washing, the detergent pump 26A (see FIG. 5) is driven to supply the detergent introduced into the machine from the detergent inlet 25A into the outer tub 7, while the softer pump 25B (see FIG. 5) is provided. By driving, the softer introduced into the machine from the softer introduction port 25B can be supplied into the outer tub 7.

  The washing / drying machine 1 also has a function of drying laundry, and a gas burner for generating heated air by heating air taken from outside the machine is provided on the upper rear side in the housing 2, for example. 23 is arranged. The gas burner 23 is accommodated in, for example, a box-shaped gas burner accommodating body 23A having a space as a heating chamber therein. For example, a fan 21 is disposed on the rear side of the housing 2, and the fan 21 is rotationally driven by a fan motor 21 </ b> A, so that a plurality of suction ports 27 formed in the upper back of the housing 2 are used. Air outside the machine is taken into the gas burner container 23 </ b> A, and heated air is generated by the action of the gas burner 23.

  The gas used in the gas burner 23 is introduced into the machine from a gas supply port 23B formed on the back surface of the housing 2, for example. At the time of drying, the gas introduced into the machine from the gas supply port 23B can be supplied to the gas burner 23 by opening the gas valve 23C (see FIG. 5).

  On the inner surface of the gas burner housing 23A, for example, a thermocouple 41 for detecting whether or not the gas burner 23 is ignited, a burner thermistor 42 for detecting the temperature in the heating chamber, and the temperature in the heating chamber are constant. An inlet thermostat 43 is attached for detecting that the value has exceeded the value and detecting an abnormally high temperature state of the heating chamber.

  For example, one end of a blower pipe 61 extending toward the right side is connected to the gas burner housing 23 </ b> A, and the other end of the blower pipe 61 is connected to the right end surface of the outer tub 7. It is connected to. The introduction air passage member 62 extends to the central portion of the right end surface of the outer tub 7, and the warm air sent through the blower pipe 61 enters the outer tub 7 from the central portion of the right side surface of the outer tub 7. It comes to be blown. An inlet thermistor 44 is attached to the inside of the introduction air passage member 62, for example, at a position near the center of the right end surface of the outer tub 7, and the temperature of the hot air flowing into the outer tub 7 is detected by the inlet thermistor 44. Be able to.

  At the time of drying, drying can be performed satisfactorily by rotating the drum 10 and repeating the tumbling of the clothes accommodated in the drum 10 while blowing warm air into the outer tub 7.

  For example, a vent hole 71 for discharging the air in the outer tub 7 is formed in the rear lower portion of the right end surface of the outer tub 7. Further, on the right end surface of the outer tub 7, for example, a lead-out air passage member 63 for guiding the air in the outer tub 7 discharged from the vent 71 to the fan 21 side is attached. An outlet thermistor 45 is attached in the outlet air passage member 63 in the vicinity of the vent 71, for example, and the outlet thermistor 45 detects the temperature of the air flowing out from the outer tub 7 through the vent 71. Can be done. Further, in the vicinity of the end portion on the side opposite to the vent 71 in the outlet air passage member 63, for example, it is detected that the temperature of the air flowing out from the outer tub 7 has become a certain value or more, and the outlet air passage member An outlet thermostat 46 for detecting an abnormally high temperature state is attached.

  On the right rear side in the housing 2, for example, a lead-out pipe 64 coupled to the middle part of the drainage channel from the discharge port 16 to the drainage hose connection port 20 </ b> A extends in the vertical direction. The air sent through the lead-out air path member 63 flows into the lead-out pipe 64 from the opening 64 </ b> A formed in the middle of the lead-out pipe 64 through the blower pipe 65, and passes through the inside of the lead-out pipe 64. It flows upward. A guide air passage member 66 for guiding the air from the lead-out pipe 64 to the fan 21 is connected to the upper end of the lead-out pipe 64.

  The air discharged from the vent hole 71 of the outer tub 7 includes lint (so-called lint) separated from the clothing during the drying process. For example, the joint between the lead-out pipe 64 and the guide air path member 66 captures lint contained in the air sent from the outer tub 7 side via the lead-out air path member 63, the blower pipe 65, and the lead-out pipe 64. A lint filter 67 is arranged along the horizontal plane. The lint filter 67 is made of, for example, a metal mesh member. The lint contained in the air flowing from the lower side to the upper side in the outlet pipe 64 is captured while the air passes through the lint filter 67 and adheres to the lower surface of the lint filter 67.

  The air after the lint has been removed by the lint filter 67 is guided through the induction air passage member 66 into the fan casing 21 </ b> B that houses the fan 21. Then, the air sent through the induction air passage member 66 circulates in the fan casing 21B by the function of the rotating fan 21, and the machine starts from the exhaust port 28 that opens rearward from the lower back of the housing 2. Discharged outside. That is, the washing / drying machine 1 has a so-called open-type exhaust air passage that discharges air after being blown onto clothes during drying to the outside of the machine.

  One of the features of this embodiment is that a lint nozzle 68 for blowing water from the downstream side (upper side) of the air flow direction (from the lower side to the upper side) to the lint filter 67 is provided. More specifically, a lint nozzle 68 for injecting water downward is attached to the upper surface of the guide air passage member 66 facing the inlet from the outlet pipe 64, and the lint nozzle 68 has a water supply port 15 </ b> A. A hose 68 </ b> A that guides a part of the water introduced from the nozzle to the lint nozzle 68 is connected. When the lint nozzle valve 68B (see FIG. 5) is opened at a predetermined timing, water is sprayed from the lint nozzle 68 to the entire lint filter 67, and the lint captured by the lint filter 67 (attached to the lower surface of the lint filter 67) is discharged. It is washed down through the outlet pipe 64.

  According to such a configuration, the lint attached to the lint filter 67 can be washed away by jetting water onto the lint filter 67, so that the trouble of removing and cleaning the lint filter 67 can be saved and the usability is good.

  The lower end of the outlet pipe 64 is coupled to the backflow prevention member 20, for example. Therefore, the water jetted from the lint nozzle 68 to the lint filter 67 flows downward through the outlet pipe 64 and is discharged out of the machine via the backflow prevention member 20. In this embodiment, since the outlet pipe 64 extends in the vertical direction, the water sprayed onto the lint filter 67 can be guided to the backflow prevention member 20 side by gravity and discharged outside the apparatus. Therefore, since the lint attached to the lint filter 67 can be washed away, it is more convenient to use.

  The water discharged from the lead-out pipe through the backflow prevention member 20 to the outside of the apparatus passes through, for example, a lint storage tank (not shown) installed outside the apparatus and is sent to the sewer. In the process of passing through the lint storage tank, the lint contained in the waste water is stored in the lint storage tank, and the lint can be prevented from flowing into the sewer. Coin laundry employees etc. need to clean this lint storage tank regularly (for example, about once every six months), but it is necessary to remove and clean the lint filter regularly (for example, every day). If it is, it will not take time.

  FIG. 4 is a cross-sectional view showing the internal configuration of the backflow prevention member 20. 4A shows a state in which members (second check valve 202, rotating shaft 203, and torsion coil spring 204) for opening and closing the inlet 20B from the outlet pipe 64 to the backflow prevention member 20 are removed. FIG. 4B shows a state in which the inlet 20B is closed by the second check valve 202.

  In the backflow prevention member 20, for example, a connecting pipe 205 for connecting the drain pipe 17 is formed on the end surface opposite to the drain hose connection port 20A (front). The water inlet 20C from the connecting pipe 205 into the backflow prevention member 20 is, for example, a first whose upper end is attached to the inner surface of the backflow prevention member 20 so as to be rotatable about the rotation shaft 206. The check valve 201 can be opened and closed.

  At the time of drainage, the first check valve 201 is pushed backward by the water sent from the drain pipe 17 through the inlet 20C, and the first check valve 201 is rearward about the rotation shaft 206 (see FIG. 4, the water from the drain pipe 17 can flow into the backflow prevention member 20. When the drainage is completed, the first check valve 201 is rotated to the near side (clockwise in FIG. 4) by its own weight and the inflow port 20C is closed, so that water flows into the drainage pipe 17 from the backflow prevention member 20 side. Backflow can be prevented.

  Further, since air in the outer tub 7 is discharged from the exhaust port 28 during drying, the pressure in the outer tub 7 and the drain pipe 17 communicating with the outer tub 7 is reduced. Therefore, at the time of drying, a force acts on the first check valve 201 in the direction (front) in which the inlet 20C is closed, and the inlet 20C is closed.

  On the upper surface of the backflow prevention member 20, for example, a connection pipe 207 for connecting the outlet pipe 64 is formed. The inflow port 20B of water from the connecting pipe 207 into the backflow prevention member 20 is, for example, a second end whose front end is attached to the inner surface of the backflow prevention member 20 so as to be rotatable about the rotation shaft 203. The check valve 202 can be opened and closed (see FIG. 4B). A holding plate 208 for holding the rotating shaft 203 is formed on the front side of the inflow port 20B in the backflow preventing member 20 so as to protrude. The holding plate 208 is rotated in a long hole 209 formed in the holding plate 208. By inserting the shaft 203, the rotating shaft 203 and the second check valve 202 are held in the backflow prevention member 20.

  The long hole 209 extends, for example, in a direction perpendicular to the plane along the inflow port 20B (see FIG. 4A), and the rotation shaft 203 is movable along the long hole 209. ing. The rotating shaft 203 is covered with, for example, a torsion coil spring 204, and one end of the torsion coil spring 204 abuts on a surface opposite to the inlet 20B of the second check valve 202, The other end is in contact with the inner surface of the backflow preventing member 20. Therefore, the second check valve 202 is biased in the direction of closing the inflow port 20 </ b> B by the pressing force of the torsion coil spring 204.

  At the time of drainage, water does not flow into the backflow prevention member 20 from the outlet pipe 64. Therefore, the second check valve 202 is urged upward (counterclockwise in FIG. 4) by the torsion coil spring 204 and flows. The inlet 20B is closed. Further, since air in the outer tub 7 is discharged from the exhaust port 28 during drying, the pressure in the outer tub 7 and the outlet pipe 64 communicating with the outer tub 7 is reduced. Therefore, at the time of drying, a force acts on the second check valve 202 in the direction (upward) of closing the inlet 20B, and the inlet 20B is closed.

  However, even when the inflow port 20B is closed by the second check valve 202 as described above at the time of draining or drying, the root portion of the second check valve 202 is the rotation shaft 203 of the inflow port 20B. The leading end of the second check valve 202 moves away from the inlet 20B, the leading end of the second check valve 202 hits the edge of the inlet 20B opposite to the rotation shaft 203, and 2 The root portion of the check valve 202 may be separated from the inlet 20B. In this case, there is a possibility that water flows backward from a portion where the second check valve 202 and the inflow port 20B are separated from each other.

  In this embodiment, since the rotation shaft 203 is movably attached along the long hole 209, the torsion coil spring 204 is provided even when the tip of the second check valve 202 is separated from the inlet 20B. By the reaction force based on the urging force, the rotating shaft 203 moves to the lower end side of the long hole 209 (direction away from the inlet 20B), and the tip of the second check valve 202 is brought into close contact with the inlet 20B. it can. On the other hand, when the root portion of the second check valve 202 is separated from the inlet 20B, the rotating shaft 203 is moved to the upper end side of the long hole 209 (flow) by the reaction force based on the biasing force of the torsion coil spring 204. In the direction of approaching the inlet 20B), the root of the second check valve 202 can be brought into close contact with the inlet 20B. Therefore, since the second check valve 202 can be brought into close contact with the entire circumference of the inflow port 20B, it is possible to reliably prevent water from flowing back from the backflow prevention member 20 to the outlet pipe 64.

On the other hand, when water is jetted from the lint nozzle 68 to the lint filter 67,
The second check valve 202 is pushed down by the injected water flowing downward through the outlet pipe 64, and the second check valve 202 rotates downward (clockwise in FIG. 4) about the rotation shaft 203. By moving, water from the outlet pipe 64 can flow into the backflow preventing member 20.

  FIG. 5 is a block diagram showing an electrical configuration of the washing / drying machine 1.

  In the washing / drying machine 1, a control unit 30 for controlling the entire washing / drying machine 1 is provided. The control unit 30 is composed of, for example, a microcomputer and includes a CPU 31, a ROM 32, a RAM 33, a timer 34, and the like.

And the number display unit 524 displays a number corresponding to the remaining time.

  On the upper left side of the operation display panel 5 are an operating lamp 527 that is lit when the laundry dryer 1 is operable, and an in-use lamp 528 that is lit when the laundry dryer 1 is operating. Is arranged.

  Further, when the operation of the washing / drying machine 1 is being executed, a process (washing process, rinsing process, dehydration process, drying process) being executed at that time is notified at the left center of the operation display panel 5. The process display part for performing is arrange | positioned. In this process display section, a washing process lamp 529, a rinsing process lamp 530, a dehydration process lamp 531 and a drying process lamp 532 are arranged in association with each process, and the lamp corresponding to the process being executed is lit. It is like that.

  The laundry dryer 1 according to this embodiment is biased in order to prevent resonance from occurring due to the bias of the laundry when the laundry accommodated in the drum 10 is biased, for example. (Eccentricity removal function) is removed. The eccentric removal function is achieved, for example, by changing a rotational speed of the drum 10 and dropping a part of the laundry that is biased. On the front side of the process display unit, for example, an eccentricity removal lamp 533 that is lit during execution of the eccentricity removal function is disposed. Further, on the front side of the eccentric removal lamp 533, for example, a combustion lamp 534 that is turned on when it is determined that the gas burner 23 is ignited by detection using the thermocouple 41 is disposed.

  A drum cleaning key 514 is disposed at the left front end of the operation display panel 5. If the drum washing key 514 is operated within a predetermined period (for example, within one minute after the outer lid 3 is opened), before the operation in the washing / drying machine 1 is started. In addition, the electrolyzed water generated by the electrolyzer 22 is stored in the outer tank 7 up to a certain water level (the extent that a part of the peripheral surface of the drum 10 is immersed). After that, the drum 10 is rotated for a certain time (for example, 2 minutes), so that the entire peripheral surface of the drum 10 is cleaned with electrolytic water. The drum cleaning key 514 is provided with a drum cleaning lamp 535 that is lit during execution of drum cleaning.

  The washing course start key 511, the drying course start key 512, the washing / drying course start key 513, and the drum washing key 514 constitute an operation key 51.

  FIG. 7 is a flowchart showing the contents of control by the CPU 31 when money is inserted from the money insertion slot 6A.

  When money is inserted from the money insertion slot 6A (YES in step S1), the CPU 31 determines whether or not the total amount of money inserted from the money insertion slot 6A is 200 yen or less (step). S2). If the total amount is 200 yen or less (YES in step S2), only the drying course can be executed, so the CPU 31 blinks the selectable lamp 522 of the drying course start key 512 (step S3).

  If the total amount is not 200 yen or less (NO in step S2) and 500 yen or less (YES in step S4), either or both of the washing course and the drying course can be executed. The selectable lamps 521 and 522 of the washing course start key 511 and the drying course key 512 are blinked (step S5).

  When the total amount is not 500 yen or less (NO in step S4), that is, 600 yen or more, any of the washing course, the drying course, and the washing / drying course can be executed. In this case, when the washing course start key 511 is operated to select the washing course, the washing course and the drying course corresponding to the difference amount (the amount obtained by subtracting 300 yen from the total amount) are executed. Since the operation content is the same as when the laundry drying course start key 513 is operated to execute the laundry drying course, it is not necessary to blink the selectable lamp 521 of the laundry course start key 511. Accordingly, in this case, the CPU 31 blinks only the selectable lamps 523 and 522 of the washing / drying course start key 513 and the drying course start key 512 (step S6).

  FIG. 8 is a flowchart showing the control contents performed by the CPU 31 in response to the operation of the start keys 511 to 513.

  When the start keys 511 to 513 in which the selectable lamps 521 to 523 are blinking are operated (YES in step T1), the CPU 31 determines that the start keys are the drying course start key 512, the washing course start key 511, and the washing and drying course. Different control is performed depending on which one of the start keys 513 is used.

  When the operated start key is the drying course start key 512 (YES in step T2), the CPU 31 determines the time corresponding to the total amount of money inserted into the money insertion slot 6A (15 minutes per 100 yen). After the drying course is executed (step T3), the operation is terminated.

  When the operated start key is the washing course start key 511 (YES in step T4), the CPU 31 determines whether or not the total amount is 300 yen (step T5). When the total amount is 300 yen (YES in step T5), the CPU 31 ends the operation after executing the washing course (step T6). On the other hand, if the total amount is not 300 yen (NO in step T5), that is, if the total amount is 400 to 500 yen, the CPU 31 executes the laundry course (step T7) and then the difference (total amount). Then, the drying course (additional drying) for 300 yen is subtracted (step T8), and the operation is terminated.

  When the operated start key is neither the drying course start key 512 nor the washing course start key 511 (NO in step T4), that is, the washing / drying course start key 513, the CPU 31 has a total amount of 600 yen. Whether or not (step T9). When the total amount is 600 yen (YES in step T9), the CPU 31 ends the operation after executing the washing / drying course (step T10). On the other hand, if the total amount is not 600 yen (NO in step T9), that is, if the total amount is 700 yen or more, the CPU 31 executes the washing / drying course (step T11) and then the difference (from the total amount). A drying course (additional drying) of 600 yen is subtracted (step T12), and the operation is terminated.

  In this embodiment, when a laundry course or a washing / drying course is started by operating the washing course start key 511 or the washing / drying course start key 513, an amount (300 yen or 600 yen) required to execute each driving course. ), The additional drying is performed for the difference. Therefore, additional drying can be automatically selected simply by inserting more money than is necessary for the execution of each driving course. Compared to a configuration in which a key for instructing additional drying is provided separately. , Less time and effort to operate the keys.

  The washing / drying machine 1 is not limited to the washing course, the drying course, and the washing / drying course, but other driving courses (for example, a sterilization course for performing a rinsing process using electrolytic water, a careful course for extending the execution time of the washing process, A squeezing course that extends the execution time of the dehydration process, a cleansing course that extends the sterilization course, a careful rinsing course that increases the number of rinsing operations during the rinsing process, and the like may be executed. In this case, when a certain amount of money or more is inserted, another driving course as described above may be added.

  FIG. 9 is a flowchart showing the contents of control by the CPU 31 when the washing / drying course is executed.

  When the washing and drying course is started, first, the CPU 31 stores water up to a predetermined water level in the outer tub 7 with the drain valve 18 closed, and then rotates (forward and reverse) the drum 10 to rotate the drum 10. The washing process is executed by repeating the tumbling of the inner laundry (step EA1).

  When the washing process ends, the CPU 31 opens the drain valve 18 to drain the water in the outer tub 7 once, and after performing a dehydration operation (intermediate dehydration) for a certain time, the CPU 31 executes a rinse process (step EA2). In the rinsing step, an operation (rinsing operation) of rotating the drum 10 for a predetermined time while supplying water into the outer tub 7 and then draining it is performed a plurality of times (for example, twice). In the second rinsing operation, for example, the softer pump 26 </ b> B is driven so that the softer is mixed into the water in the outer tub 7.

  When the rinsing process is completed, the CPU 31 executes the dehydration process by rotating the drum 10 at a high speed for a predetermined time while the drain valve 18 is open (step EA3). When the dehydration process is completed, the CPU 31 opens the gas valve 23C to ignite the gas burner 23 and drives the fan motor 21A, while rotating the drum 10 to repeat the tumbling of the laundry in the drum 10 to thereby dry. A process is executed (step EA4).

  Thereafter, the CPU 31 drives the fan motor 21A in a state where the gas valve 23C is closed and the heating of the air by the gas burner 23 is stopped, thereby rotating the drum 10 while feeding the room temperature air into the outer tub 7 to rotate the drum 10 Repeat the tumbling of the laundry inside. Thereby, the cool-down operation for cooling the laundry in the drum 10 is achieved (step EA5). The cool-down operation is executed, for example, until the temperature of the laundry in the drum 10 (clothing temperature) becomes 50 ° C. or lower.

  When the cool-down operation ends, the CPU 31 starts the lint shower operation by opening the lint nozzle valve 68B and injecting water from the lint nozzle 68 (step EA6). At this time, the CPU 31 starts measuring time by the timer 34, and thereafter executes the lint shower operation until a predetermined time (for example, 1 minute) elapses (YES in step EA7), and then ends the washing and drying course. To do. When the lint shower operation for 1 minute is executed, for example, about 2 liters of water is sprayed from the lint nozzle 68.

  In this embodiment, the lint shower operation is automatically executed at the end of the washing and drying course, and the lint filter 67 is periodically cleaned, so there is no need to perform a special operation for cleaning the lint filter 67. More convenient to use.

  In the washing course, the CPU 31 executes the above steps EA1 to EA3. In the drying course, the CPU 31 executes steps EA4 and EA5. The timing of executing the lint shower operation is not limited to the above timing (at the end of the washing / drying course), but may be configured to be executed when another driving course (such as the drying course) ends, for example. Alternatively, it may be configured to be executed at the start or midway of the driving course. Further, the configuration may be such that the lint shower operation is executed during the test operation mode, or a filter cleaning key is provided on the operation display panel 5 and is executed when this key is operated. Also good.

  FIG. 10 is a flowchart for explaining the execution timing of the lint shower operation according to the modification of this embodiment.

  In this modification, the CPU 31 starts the lint shower operation by opening the lint nozzle valve 68B and injecting water from the lint nozzle 68 when the power of the washing / drying machine 1 is turned on (YES in step EB1). (Step EB2). At this time, the CPU 31 starts timing by the timer 34 and then executes the lint shower operation until a predetermined time (for example, 1 minute) elapses (YES in step EB3).

  According to the above configuration, the lint shower operation can be performed when the washing and drying machine 1 is turned on at the time of opening a coin laundry or the like. Therefore, the lint filter 67 is required at least once a day. Can be cleaned. Therefore, the amount of water used for the lint shower operation can be minimized.

  FIG. 11 is a plan view showing an external configuration of the operation display panel 105 of the washing / drying machine 1 according to another embodiment.

  In the washing / drying machine 1 according to this embodiment, a washing course for performing only a washing process (washing process, rinsing process, and dehydration process) and a drying course for performing only a drying process are not set, and a predetermined amount (for example, 30 kg). A standard course capable of executing a washing / drying course for up to laundry and a washing / drying course with a relatively small amount of water for a laundry up to a certain amount (for example, 12 kg) smaller than the predetermined amount. One of the two driving courses of the small amount course can be selected and executed. The standard course is 1600 yen, for example, and the small course is 800 yen, for example.

  In the central portion of the operation display panel 105, a washing fee (1,600 yen) for the standard course is displayed, and a start key or the like for starting the standard course is not arranged. In other words, in this embodiment, the standard course is automatically started when money equal to or greater than the washing fee (1,600 yen) of the standard course is inserted from the money insertion slot 6A.

  A small amount course key 541 for selecting a small amount course is arranged on the front side of the central portion of the operation display panel 105. When the small amount course key 541 is operated and the small amount course is selected, the small amount course is automatically started when money of the washing fee (800 yen) or more of the small amount course is inserted from the money insertion slot 6A. It has become so.

  In this embodiment, when money is thrown in excess of the washing fee necessary for the execution of the selected operation course (standard course or small amount course), the electrolyzed water generated by the electrolyzer 22 during the rinsing process is used. A course (sterilization course) that is introduced into the outer tub 7 to sterilize the laundry is added and executed. The fee required to add the sterilization course is, for example, 100 yen, and if the additional fee exceeds 100 yen, the excess money will be returned from the money return slot 6C. It has become.

A drum cleaning key 542 is arranged on the right side of the small amount course key 541.
If the drum washing key 542 is operated within a predetermined period (for example, within one minute after the outer lid 3 is opened), before the operation in the washing / drying machine 1 is started. In addition, the electrolyzed water generated by the electrolyzer 22 is stored in the outer tank 7 up to a certain water level (the extent that a part of the peripheral surface of the drum 10 is immersed). After that, the drum 10 is rotated for a certain time (for example, 2 minutes), so that the entire peripheral surface of the drum 10 is cleaned with electrolytic water.

  In the center of the rear end portion of the operation display panel 105, for example, a business lamp 551 that is turned on when the washing / drying machine 1 is in an operable state is disposed. On the front side of the operating lamp 551, for example, a numerical display capable of switching and displaying the total amount of money inserted (inserted amount) from the money insertion slot 6A and the remaining time until the end of the running course being executed. A portion 552 is disposed. Until the operation of the washing / drying machine 1 is started, the input amount selection lamp 553 arranged in the vicinity of the characters “input amount” is lit, and the input amount is displayed on the number display portion 552. In addition to the notification, the number display unit 552 displays a number corresponding to the input amount. On the other hand, when the operation of the washing / drying machine 1 is started, the remaining time selection lamp 554 arranged in the vicinity of the characters “remaining (about)” is turned on, and the remaining time is displayed on the number display portion 552. And a number corresponding to the remaining time is displayed on the number display portion 552.

  For example, a drum cleaning lamp 555 that is lit during execution of drum cleaning is disposed in the left center portion of the operation display panel 105. Further, on the front side of the drum cleaning lamp 555, for example, a sterilization course lamp 556 that is turned on when a sterilization course is added is disposed.

  In order to notify the front side of the sterilization course lamp 556 of the process (washing process, rinsing process, dehydration process, drying process) being performed at the time when the operation of the washing / drying machine 1 is being performed. The process display section is arranged. In this process display section, a washing process lamp 557, a rinsing process lamp 558, a dehydration process lamp 559, and a drying process lamp 560 are arranged in association with each process, and the lamp corresponding to the process being executed is lit. It is like that.

  The small amount course key 541 and the drum cleaning key 542 constitute 51 operation keys. On the other hand, an operating lamp 551, a number display section 552, an input amount selection lamp 553, a remaining time selection lamp 554, a drum washing lamp 555, a sterilization course lamp 556, a washing process lamp 557, a rinsing process lamp 558, a dehydration process lamp 559, and The drying process lamp 560 constitutes the display unit 52.

  FIG. 12 is a flowchart showing the contents of control by the CPU 31 when money is inserted from the money insertion slot 6A.

When money is inserted from the money insertion slot 6A (YES in step P1), the CPU 31 determines whether or not a small amount course is selected by operating the small amount course key 541 (step P2). If the small amount course is selected (YES in Step P2), the CPU 31 determines whether or not the total amount of money inserted from the money insertion slot 6A is 800 yen or more (Step P3). . If the total amount is not 800 yen or more (NO in step P3), the CPU 31 again monitors whether or not money is inserted from the money insertion slot 6A (step P1).
On the other hand, if the total amount is 800 yen or more (YES in step P3), a small course is started (step P4).

  When the small amount course is not selected (NO in Step P2), the CPU 31 determines whether or not the total amount of money inserted from the money insertion slot 6A is 1600 yen or more (Step P7). If the total amount is not 1600 yen or more (NO in step P7), the CPU 31 again monitors whether or not money is inserted from the money slot 6A (step P1), while the total amount is 1600 yen or more. If it is (YES in step P7), the standard course is started (step P8).

  Thereafter, if an additional fee is charged within a certain time (for example, before the start of the rinsing process) (YES in step P5), the CPU 31 sets to execute the sterilization course in the rinsing process. (Step P6). This additional fee is charged when, for example, the total amount of money inserted to start each driving course (standard course or small amount course) exceeds the price of each driving course (1600 yen or 800 yen). Is also included.

  In this embodiment, after the money is inserted and the standard course or the small amount course is started, when money is additionally inserted in excess of the amount necessary for the execution of each driving course (1600 yen or 800 yen), A sterilization course is added and executed. Therefore, the sterilization course can be automatically selected simply by inserting more money than is necessary for the execution of each driving course. Compared with a configuration in which a key for instructing the sterilization course is separately provided. As a result, the time and effort of key operation is reduced, and it is more convenient to use.

  However, it is not limited to the above-described configuration, for example, a configuration in which operation can be performed only in the standard course without setting a small amount course, and the amount of money (1600 yen) necessary for the execution of the standard course has been input In some cases, the standard course may be automatically started, and the additional sterilization course may be added and executed when money is additionally input exceeding a necessary fee. In this case, since it is not necessary to provide a key for selecting a driving course or a key for instructing a sterilization course, it is possible to save time and trouble of key operation.

In addition, the washing and drying machine 1 is not limited to a standard course, a small amount course, and a sterilization course,
Other driving courses (for example, a careful course that extends the execution time of the washing process, a squeezing course that extends the execution time of the dehydration process, a cleansing course that extends the sterilization course, and the number of rinsing operations during the rinsing process are increased. You may be able to run a carefully rinse course, etc.). In this case, when a certain amount of money or more is inserted, another driving course as described above may be added.

  The present invention is not limited to the contents of the above embodiments, and various modifications can be made within the scope of the claims.

  The lint filter 67 is not limited to the configuration arranged along the horizontal plane, and may be configured along the direction inclined with respect to the horizontal direction.
