Description

  The present invention relates to a control method for a drum-type washing / drying machine having a drum-type washing machine added with a drying function for circulating drying air.

  In a washing and drying machine that performs washing, rinsing, dehydration, and drying in a rotating drum housed in a common water tank, detergent bubbles generated during the washing process are placed in the air duct provided to carry out the drying process. It is required to be configured not to flow in. In particular, in the case of adopting foam cleaning in which the washing effect is improved by wrapping and washing laundry with a large amount of detergent foam, the detergent foam tends to overflow into the air duct.

  The state in which a large amount of detergent foam is generated in the water tank is not necessarily only when the foam cleaning is employed. Since it is left up to the user to determine the type and amount of detergent and the amount of laundry, the optimal detergent is not always used in the optimal amount, and a state where a large amount of detergent foam fills the tank. It is necessary to assume. In the washing and drying machine, the process from washing to drying is performed in a common aquarium. Therefore, if excessive detergent bubbles are generated during the washing process, the air blower or air heating means provided to carry out the drying process. The detergent bottles into which the detergent foam has flowed in and the attached detergent bubbles have dried may not only impede the moving parts, but may also adhere to clothes that the detergent bottle dries during the drying process. Therefore, it is necessary to prevent the detergent foam generated in the washing process from flowing into the components provided for the drying process.

  In order to prevent detergent foam from flowing into the air duct, drum-type laundry drying that controls the blower fan and heater provided to carry out the drying process to prevent detergent foam from entering the air duct A machine is known (see Patent Document 1). In this drum-type washing and drying machine, when a washing process is performed, the detergent fan is foamed by rotating the rotating drum to generate a large amount of detergent foam. Operate and blow air from the air duct to the water tank. Even if this blowing is less than the blowing amount during the drying step, it is possible to prevent the detergent bubbles from entering the blowing duct. Moreover, when blowing air is heated with a heater, the detergent foam which is going to enter can be eliminated.

  However, in the above prior art, since the detergent bubbles are prevented from entering the air duct by air blowing or heating, there is a problem that extra power consumption occurs to operate the air blowing fan or heater even during the washing process. It was. In addition, since air blow and heating are controlled in conjunction with the control of the washing process, and the air blow amount and the heat amount are controlled, there is a problem that the control operation is complicated.

  The present invention was devised in view of the problems associated with the prior art described above, and the object of the present invention is a drum type that prevents detergent bubbles from entering the air duct without using a configuration for the drying process. It is in providing the control method of a washing dryer.

In order to achieve the above object, the present invention performs a washing, rinsing, and dewatering steps by a rotating drum that is driven to rotate in a water tank, and is connected to an air inlet opening that opens to the water tank. feeds feed heated air from the heated air generating means towards, the moisture air deprived of moisture from the laundry heated air is accommodated in the rotary drum is discharged from the water tank, again heated by hot air generating means after dehumidified A method for controlling a drum-type washing / drying machine that performs a drying process of drying laundry by circulating air that is supplied as air, and the pipe is normally opened near the inlet of the heated air blowing duct It arranged a pipe shutter so that the state, at least when the washing cycle is performed, the conduit shutter is controlled to close the heating air blower conduit, said by the pipe shutter When a pause operation is performed during operation in a state in which the control to close the hot air blowing pipe is performed, the pipe shutter is maintained for a predetermined time in a state in which the heated air blowing pipe is closed, and then the pipe The shutter is controlled to be in a state in which the heated air blowing duct is opened .

According to the above control method, the pipeline shutter provided so that the pipeline is always opened in the vicinity of the intake port of the heated air blower pipeline is closed at least when the washing process is performed. Therefore, even when foam washing is performed in which a large amount of detergent foam is generated in the washing process, the detergent foam overflowing from the intake port is prevented from flowing into the heated air blowing duct. When the operation of closing the pipeline by the pipeline shutter is stopped, the pipeline shutter returns to the state in which the pipeline is opened, so that an air circulation path for performing the drying process is secured. In addition, if the pipeline shutter is released from the closed state due to a temporary stop of the operation, the opened tube may be used in the case where detergent bubbles have entered the heated air blowing duct from the intake port. There is a risk that detergent bubbles may intrude into the heated air blowing duct from the road shutter, but by keeping the pipe shutter closed for a predetermined time, the detergent foam may flow down into the water tank during that time. Therefore, even if the pipe shutter is opened after a predetermined time, the detergent bubbles do not flow into the heated air blowing pipe.

In addition, the present invention performs washing, rinsing, and dewatering steps by a rotating drum that is driven to rotate in the water tank, and also heated air toward a heated air blower pipe connected to an air inlet opening in the water tank. Heated air is supplied from the generating means, and the hygroscopic air from which the heated air has taken away moisture from the laundry stored in the rotating drum is discharged from the water tank, dehumidified, and then supplied as heated air again by the heated air generating means. A drum-type washing and drying machine control method for executing a drying process for drying laundry by circulating air so that the pipe line is always open in the vicinity of the intake port of the heated air blowing pipe line When a pipe shutter is provided and at least when the washing process is performed, the pipe shutter is controlled to close the heated air blowing pipe, and before the power is shut off at the end of the operation, the pipe shutter is controlled. And executes a predetermined number of times opening and closing of the shutter.

According to the above control method, the pipeline shutter provided so that the pipeline is always opened in the vicinity of the intake port of the heated air blower pipeline is closed at least when the washing process is performed. Therefore, even when foam washing is performed in which a large amount of detergent foam is generated in the washing process, the detergent foam overflowing from the intake port is prevented from flowing into the heated air blowing duct. When the operation of closing the pipeline by the pipeline shutter is stopped, the pipeline shutter returns to the state in which the pipeline is opened, so that an air circulation path for performing the drying process is secured. Also, by opening and closing the pipeline shutter a predetermined number of times before the power shut-off control at the end of operation, even if detergent bubbles that have entered from the intake port adhere to the movable part of the pipeline shutter, the opening and closing operation Since the adhering component is removed from the movable part by repeating the above, it is possible to prevent the adhering detergent bubbles from adhering and hindering the operation of the movable part.

In the above control method, when the pipeline shutter is controlled to close the heated air blowing pipeline from the washing process to the completion of the rinsing process, the detergent foam generated in the washing process remains until the subsequent dehydration and rinsing process. In such a case, it is possible to prevent the heated air blowing duct from entering due to the wind pressure accompanying the rotation of the rotating drum .

  According to the present invention, a large amount of detergent foam is generated in a water tank even when a drum-type washing / drying machine is configured so that foam washing can be performed so that a large amount of detergent foam is generated in a washing process to improve a washing effect. It is possible to prevent the detergent bubbles from overflowing from the air inlet opening and to flow into the air duct provided for carrying out the drying process by controlling the duct shutter. Since the washing and drying machine carries out the washing process to the drying process in a common water tank, it is necessary to prevent the phenomenon in the washing process from affecting the drying process. The required purpose can be achieved by blocking the provided pipe line.

  The present embodiment shows an example in which a drying function by a heat pump system is applied to a drum type washing machine to constitute a drum type washing and drying machine. A drum-type washing machine has many components arranged in a washing machine casing, and the washing machine casing is limited in volume so that the drum-type washing machine can be installed in a limited area such as a waterproof pan. Among them, a heat pump having a volume larger than that of the heater system can be disposed in the washing machine casing, and can be efficiently dried with less power consumption.

  FIG. 1 mainly shows the configuration of the drying function in the drum-type washing / drying machine 1 according to the embodiment, and is displayed in a state modified from the actual form in order to show all the components of the drying function. . As shown in a side view in FIG. 2, the actual shape is formed in a curved surface whose front side is inclined from the vertical direction, and a door body 8 (see FIG. 1) for taking in and out the laundry is provided on the inclined curved surface. .

  In FIG. 1, a drum drive motor 4 is attached to the back surface of the water tank 3 containing the rotary drum 5, and the rotary shaft 17 of the rotary drum 5 supported by a bearing 16 provided in the water tank 3 is used as the drum drive motor 4. The water tank unit 10 is configured to be driven to rotate. The water tank unit 10 is supported by a suspension structure in the washing machine casing 2 at an inclination angle in which the rotation axis of the rotary drum 5 is upward on the front side. The water tank 3 and the rotating drum 5 are each opened on the front side, and the laundry can be taken in and out from the laundry entrance 6 of the rotating drum 5 by opening the door body 8 provided in the front of the washing machine housing 2. . When the door body 8 is closed, the bellows 43 provided in the opening of the water tank 3 is in close contact with the inner surface of the door body 8, so that the water tank 3 becomes a watertight and airtight space, and each process of washing, rinsing, dehydration and drying is performed. When running, water and air will not leak to the outside.

  A heat pump unit (heated air generating means) 20 is disposed so that the water tub unit 10 is inclined in the washing machine casing 2 so as to fit in a space formed in the lower part on the back side of the washing machine casing 2. . The washing machine housing 2 has a limited volume so that the drum-type washing / drying machine 1 can be installed in an existing installation place with a limited area such as a waterproof pan. When the supporting suspension structure or the components for water supply, drainage, etc. are accommodated, the excess space is reduced, but the washing machine housing 2 is arranged without increasing the size by configuring the heat pump unit 20 compactly. Making it possible.

  The heat pump unit 20 includes a compressor (not shown), a heat absorber 28, a heat radiator 29, and the like housed in a unit case 21, and the components are integrated. As shown in FIG. 2 is mounted on the frame 58 from the back surface, and a lower back plate 78 is attached to the lower back of the washing machine housing 2 so that it is disposed in the washing machine housing 2. An exhaust connection hose 33 formed of a flexible material in a bellows structure is connected to an exhaust port for heated air that opens in the unit case 21, and the exhaust connection hose 33 has one end connected to the intake port 11 that opens in the bottom surface of the water tank 3. It is connected and connected to a heated air blow duct (heated air blow duct) 13 attached to the back surface of the water tank 3. An intake connection tube 32 is connected to the intake port of the hygroscopic air that opens in the unit case 21, and an intake connection hose 49 formed of a flexible material between the intake connection tube 32 and the hygroscopic air blowing duct 14. Connected by.

  With the piping connection, the heat pump unit 20 and the water tank unit 10 are connected by the air supply path shown in FIG. An intake port 11 is formed on the back surface of the water tank 3 and an exhaust port 12 is formed on the side peripheral surface. A heated air blower duct 13 and an exhaust connection hose 33 are provided between the intake port 11 and the heat pump unit 20. The exhaust port 12 and the heat pump unit 20 are connected to each other by a suction connection hose 49 and a suction connection cylinder 32 from a hygroscopic air blowing duct 14 provided with a filter unit 60 and a blower fan 15. An air circulation path for air is formed.

  As shown in FIG. 1, the heat absorber 28 constituting the heat pump unit 20 is inclined so that the upper portion thereof is close to the radiator 29, and is inclined with respect to the radiator 29 that is inclined to the heat absorber 28 side. Thus, each one side faces diagonally at a predetermined interval. The wall surface of the unit case 21 is formed on the other surface side of the heat absorber 28 at a predetermined interval substantially parallel to the inclination of the heat absorber 28, and the wall surface of the unit case 21 is disposed on the other surface side of the heat radiator 29. An air intake space and an air exhaust space are formed between the heat sink 28 and the heat radiator 29 and the wall surface, respectively. Both end portions of the heat absorber 28 and the radiator 29 are left and right so that an air flow path is formed from the intake space on the heat absorber 28 side through the heat absorber 28 and the radiator 29 to the exhaust space on the radiator 29 side. The heat absorbing / dissipating unit held by the pair of side wall plates 37 is accommodated in the unit case 21.

  In this way, the front side wall surface of the unit case 21 is formed to be inclined so as to escape the water tank unit 10, and the rear side wall surface of the unit case 21 is formed in a substantially vertical direction along the back surface of the washing machine housing 2. Thus, the limited space can be utilized to the maximum, and the heat pump unit 20 can be disposed in the limited space formed behind the water tank unit 10. Moreover, since both ends of the heat absorber 28 and the heat radiator 29 are held by the pair of side wall plates 37, the heat absorber 28 and the heat radiator 29 can be accommodated in the unit case 21 as a heat absorption / heat radiation unit. Incorporation into or removal from the work can be facilitated, and workability can be improved.

  The drum-type washing / drying machine 1 configured as described above can perform washing, rinsing, dehydration, and drying processes. When performing the washing process, the door body 8 is opened and the laundry is placed in the rotating drum 5. The drum 5 is rotated and driven by the drum drive motor 4 by supplying water and detergent into the water tank 3 from a water supply pipe (not shown) and starting the washing process, and is provided at a plurality of locations on the inner peripheral surface. Washing is carried out by repeating the action of tapping which the stirring blade 7 lifts the laundry upward and drops it from above.

  In this washing process, a high-concentration detergent is mixed with the injected water, a large amount of detergent foam is generated by the rotation of the rotating drum 5, and foam washing is performed to improve the washing effect by wrapping the laundry with detergent foam. be able to. Since a large amount of detergent foam is generated in the water tank 3 in the foam cleaning, when there is a large amount of laundry, the detergent foam filled in the water tank 3 is heated by air from the intake port 11 that opens at the bottom of the water tank 3. There is a risk of flowing into the duct 13. Since it is not preferable that the detergent bubbles flow into the heated air blowing duct 13 or the heat pump unit 20 on the upstream side in the blowing direction, the heated air blowing duct 13 can be closed in the vicinity of the intake port 11 at least during the washing process. A pipeline shutter 81 is provided as described above.

  As shown in FIG. 4, the pipe shutter 81 is provided in the vicinity of the air inlet 11 of the heated air blowing duct 13 attached to the bottom surface of the water tank 3. The pipe shutter 81 includes a blade body 83 formed in a shape corresponding to the pipe cross-sectional shape of the heated air blower duct 13 in the pipe line, and draws out a rotating shaft 82 to which the blade body 83 is fixed. It is attached to the heated air blowing duct 13 so as to be rotatable.

  A coil spring 84 and a drive wheel 85 are attached to the rotation shaft 82. The coil spring 84 urges the rotating shaft 82 so as to be in a rotational direction in which the blade 83 opens the pipe. Further, the driving wheel 85 rotates the rotating shaft 82 in the direction opposite to the biasing direction of the coil spring 84 by applying a tensile driving force exceeding the biasing force of the coil spring 84 to the wire 86 having one end fixed thereto.

  FIG. 5 shows a state in which the rotating shaft 82 is rotated in the urging direction by the urging force (A) of the coil spring 84 constantly applied to the rotating shaft 82, and the blade body 83 opens the heated air blowing duct 13 as indicated by a solid line. The rotating position of the blade body 83 is shown. The rotating shaft 82 is rotated by the urging force (A) applied from the coil spring 84, and the heated air blowing duct 13 indicated by a solid line in FIG. By applying a driving force (B) that rotates the rotating shaft 82 against the urging force (A) of the coil spring 84 from the open state of the pipe line to the driving wheel 85, the rotating shaft 82 rotates and the blades The body 83 can be rotated to a position where the pipe line indicated by the broken line in FIG. 5 is closed. When the pipe shutter 81 is operated in a state in which the pipe is closed, the contact piece 92a formed on the peripheral edge of the elastic body 92 provided on the blade body 83 is deformed and the inner peripheral wall of the heated air blowing duct 13 is deformed. Therefore, the pipe line is closed with good sealing performance.

  The structure for applying the driving force (B) to the rotating shaft 82 can be arbitrarily configured, but here, as the structure for applying a tensile driving force for rotating the rotating shaft 82 in the rotating direction against the urging force (A). Yes. As shown in FIG. 4, the other end of the wire 86 having one end fixed to a drive wheel 85 fixed to the rotating shaft 82 is connected to a geared motor 87. By driving the geared motor 87, the wire 86 is wound up and the drive wheel 85 is rotated.

  The drive wheel 85 is fixed to the rotating shaft 82 at an attachment angle as shown in FIG. Since one end of the wire 86 is fixed on the rotation circumference of the driving wheel 85, when a driving force (B) in the pulling direction exceeding the urging force (A) by the coil spring 84 is applied to the wire 86 from the geared motor 87, FIG. As shown in FIG. 5C, the drive wheel 85 rotates approximately 90 degrees, and the rotating shaft 82 rotates against the urging force (A) of the coil spring 84. From the state where the pipe line indicated by the solid line is opened, as shown by the broken line, the peripheral edge of the pipe abuts against the step part 90 and rotates to the position where the heated air blower pipe line 13 is closed.

  As shown in FIG. 4, the wire 86 is relayed by a spring 89 disposed in the guide cylinder 88 in the middle of being connected to the geared motor 87. This operating position error is absorbed by the expansion and contraction of the spring 89 and prevents excessive pressure from being applied to each part.

  The operation of the pipe shutter 81 configured as described above is incorporated in a control program in which the control unit provided in the drum type washing and drying machine 1 controls the operation operation, and the operation of the geared motor 87 is controlled, whereby the heated air blowing duct 13 is operated. Can be opened and closed.

  Since the pipeline shutter 81 is always in a state in which the heated air blowing duct 13 is opened by the biasing by the coil spring 84, the heated air blowing duct 13 can be closed by operating the geared motor 87 by the control operation. In order to close the pipeline of the heated air blowing duct 13 by the pipeline shutter 81, power consumption for operating the geared motor 87 is generated even with a small amount of power consumption, so that detergent bubbles may enter the heated air blowing duct 13. The basic control operation is to operate the duct shutter 81 and close the heated air delivery duct 13 only while a certain washing process is being performed.

  However, when control is performed to open the pipe shutter 81 at the same time as the end of the washing process, the detergent bubbles remaining in the water tank 3 and the detergent bubbles that have entered from the intake port 11 during the washing process are caused by the heated air blowing duct 13. In the case where it remains on the downstream side of the pipe shutter 81, there is a possibility that the heated air blowing duct 13 may be penetrated by the wind pressure accompanying the rotation of the rotating drum 5 in the process of dehydration and rinsing. Therefore, it is desirable to more reliably perform the control operation in which the pipeline shutter 81 is closed until the rinsing process is finished and the final dehydration process is started. That is, when the washing operation is completed in the washing process, the dehydrating operation is performed to dehydrate the dirty washing water from the laundry, and then the rinsing process is performed. Usually, the dehydrating operation is performed after two rinsing operations. Therefore, when the final rinsing operation is completed and the dehydration process is started, control to open the pipe shutter 81 is performed.

  When a pause operation input is made to the drum-type washing / drying machine 1 that performs control for closing the heated air blowing duct 13 using the duct shutter 81 by the above-described control operation, the duct shutter 81 is kept at a predetermined time (for example, 1 minute), the pipeline closed state is maintained, and then the geared motor 87 is controlled to stop energization so as to open the pipeline. That is, the state in which the pipeline shutter 81 is closing the pipeline is a washing process or a rinsing process in the above control operation. Therefore, if the pipeline shutter 81 is opened in response to a temporary stop operation, the detergent bubbles are heated. There is a risk of entering the air blowing duct 13. Therefore, if the pipeline shutter 81 is controlled to open after waiting for a predetermined time, the detergent bubbles in the vicinity of the intake port 11 flow down or disappear below the water tank 3 while the predetermined time elapses. Even if the pipe shutter 81 is opened, the detergent bubbles do not enter the heated air blowing duct 13.

  Further, when all the operation operations of the drum type washing / drying machine 1 are completed, the pipeline shutter 81 can be forcibly controlled to open and close a predetermined number of times (for example, 5 times) before the power switch is controlled to be OFF. desirable. This opening / closing operation removes the detergent foam component adhering to the movable part located in the heated air blowing duct 13, so that the detergent foam component adheres to the movable part and may hinder the operation of the movable part. Can be prevented.

  In addition, during the process in which the pipeline shutter 81 closes the pipeline, the power switch may be mistakenly operated or a power failure may occur. When such an unexpected operation stop state occurs, the pipeline shutter 81 is in a state where the pipeline is opened by shutting off the power, so that detergent bubbles may enter the heated air blowing duct 13. In such a case, the rotation of the rotating drum 5 is stopped, and a large amount of detergent foam does not enter, but the liquid remaining after the foam disappears flows down into the heated air blowing duct 13. It can be. However, as shown in FIG. 5, a stepped portion 90 in which the peripheral portion of the blade body 83 is in pressure contact is formed at the portion where the pipe shutter 81 of the heated air blowing duct 13 is disposed. The flow is prevented by the part 90. Furthermore, as shown in FIG. 4, if the barrier 91 is formed on the inner bottom surface of the portion where the heated air blowing duct 13 bends downward, the obstacle of the pipe shutter 81 and the liquid beyond the stepped portion 90 may flow. Inflow into the heat pump unit 20 can be prevented.

  In the drum type laundry dryer 1, the washing process to the drying process can be continuously performed, and only the drying process can be performed in order to dry wet clothes and the like. In the drying process, when the laundry or wet clothes (hereinafter collectively referred to as clothing) that has finished dewatering are accommodated in the rotating drum 5 and the drying process is started, the rotating drum 5 rotates at a speed corresponding to the drying process. The heat pump unit 20 and the blower fan 15 are driven at the same time as the clothes are rotated and the clothes are blown, and the duct shutter 81 is in the state where the duct is opened, so that the circulation of the drying air is started as shown in FIG. Is done.

  In the heat pump unit 20, the refrigerant is compressed by the operation of the compressor, and by this pressure, the refrigerant flows through the refrigerant pipe and circulates from the radiator 29 through the throttle means to the heat absorber 28. Since the heat of the compressed refrigerant flows into the radiator 29 and is radiated to the air in contact with the fins provided in the refrigerant pipe, the blown air is heated and heated air is generated. The heated air enters the water tank 3 through the exhaust connection hose 33 and the heated air blowing duct 13 from the exhaust opening that opens to the unit case 21 and enters the water tank 3, and the air inlet 26 formed on the bottom surface of the rotating drum 5 and the peripheral surface. Is fed into the rotary drum 5 through the through-hole 9 formed in

  The heated air becomes moisture-absorbed air that has taken moisture from the clothes stirred by the rotation of the rotating drum 5 and is discharged from the exhaust port 12. When passing through the filter unit 60, lint such as lint is captured by the filter and blown It passes through the fan 15 and is discharged to the hygroscopic air blowing duct 14. The hygroscopic air blown to the hygroscopic air blowing duct 14 enters the heat pump unit 20 through the intake connection hose 49 and the intake connection cylinder 32, and passes through the heat absorber 28 through which the refrigerant reduced in pressure by the throttle means flows. Condensed water generated by dehumidifying and dehumidifying sensible heat and latent heat is dripped into the water storage section 34, and the dehumidified and dried air enters the radiator 29 and forms an air circulation that is heated again. Is done. The water stored in the water storage section 34 is discharged into the water tank 3 by operating a drain pump (not shown) at regular intervals, and the drain valve 19 is opened to pass through the drain pipe 25 from the drain port. Drained outside.

  The structure of the clothes drying apparatus that heats and dehumidifies the drying air by the heat pump unit 20 collects the heat absorbed by the heat absorber 28 with the refrigerant and dissipates the heat again from the radiator 29, so that the energy input to the compressor exceeds the energy. The amount of heat can be given to the clothes, and it is possible to reduce the drying time and save energy.

  In the drum-type washing and drying machine 1 in the embodiment described above, it is assumed that a drying function using a heat pump is provided, but even in the case of a configuration provided with a heating means and a dehumidifying means by a heater as a drying function, It is effective to provide and configure the pipe shutter 81 according to the present invention.

  As described above, according to the present invention, even when a large amount of detergent foam is generated as in the case where foam washing is performed in which a large amount of detergent foam is generated in the washing process to improve the cleaning effect, the pipeline shutter is generated. Thus, it is possible to prevent the detergent bubbles overflowing from the air inlet opening in the water tank from flowing into the pipe line for carrying out the drying process. Since the washing and drying machine carries out the washing process to the drying process in a common water tank, it is necessary to prevent the phenomenon in the washing process from affecting the drying process. It is possible to provide a drum-type washing and drying machine that achieves a required purpose by blocking the provided pipe line.
