And is discharged to the outside air through the opening 1a at the bottom of the outer box 1 and the gap between the outer box 1 and the top cover 6.

[0013]

The washing / drying machine having such a drying process can be said to be easy to use because it can perform from washing to drying with one unit, but it has a built-in warm air generator 19 and a dehumidifying mechanism 45. As a result, the entire body becomes large, the structure becomes complicated, and the cost increases.

In addition, drying is not always performed at the time of washing, and the washing may be completed in the washing process, and the operating efficiency of the hot air generator 19 used in the drying process is not good. Furthermore, for a user who is satisfied only with the washing process, it is necessary to separately manufacture a washing machine in which the hot air generator 19 and the like are not provided, which complicates the manufacturing line and causes an increase in cost.

In order to solve such inconveniences, the washing machine itself is not provided with a drying function, and the washing machine is constructed as a separate detachable unit from the washing machine. Connected the dryer to the washing machine,
It has also been considered to send warm air from the drying device to the washing machine to dry the laundry.

[0016] However, if the control of the drying apparatus is configured separately from that of the washing machine, it is necessary to operate the drying apparatus separately from the operation of the washing machine. All the settings such as setting the appropriate drying time must be performed on the side of the drying apparatus, and the workability is not good. Further, even though the load of the laundry is determined at the start of the washing, the data is not fed back to the drying operation, so that an appropriate drying operation cannot be expected.

An object of the present invention is to eliminate the disadvantages of the prior art, and to connect a drying device to a washing machine in a detachable manner, so that a drying function can be easily added to a washing machine without a drying function. In addition, the user can select the addition of a drying function according to the user's request, and it is easy to use. It is possible not only to simplify the production line and reduce costs, but also to control the drying operation easily and use the load adopted in the washing process. An object of the present invention is to provide a washing machine operation control method in which data such as an amount can be used in a drying process and an appropriate drying operation can be easily performed.

[0018]

To achieve the above object, the present invention firstly provides an outer box provided with a top cover and having an open top, a cover for covering the opening of the outer box, A washing and spin-drying tub disposed rotatably in the washing and spin-drying tub, and a rotating blade disposed at the bottom of the washing and spin-drying tub, and a hole communicating with the washing and spin-drying tub is provided at an arbitrary position on the upper portion of the washing machine; In a washing machine having a detachable drying device for supplying hot air to the laundry in the washing and dewatering tub and drying the laundry, the washing, rinsing, and dehydrating processes by the washing machine using a control device provided in the washing machine. In addition to the operation control of the above, by controlling the operation of the drying process by the drying device, the drying device can be controlled only by the control device on the washing machine side. Even if the drying equipment is optional for the washing machine It can be used as the, to have good usability.

Second, the washing machine has an output terminal for supplying power to the drying device, and when the drying step is selected, power supply to the drying device from the output terminal is started. Since the drying device is activated, the power of the drying device is taken from the washing machine, so that the drying device does not need to be taken from the wall of the room or the like. Secure is ensured. Also, if the setting for selecting the drying process is made, the power is automatically supplied to the drying device in conjunction with this, and the drying device operates,
No special operation such as turning on the power on the drying device side is necessary for operating the drying device, the operability is good, and the drying device can be reliably operated.

Third, since the output terminal for supplying power to the drying device is in the form of a commercially available outlet, the connection is easy and the operation is easy when the drying device can be connected separately to the washing machine. Good drying properties make it possible to use a commercially available dryer or futon dryer as the drying device.

Fourth, a temperature sensor for measuring the temperature inside the washing machine is provided in the washing machine, and the temperature measured by the temperature sensor during the operation of the drying device is set to a first temperature preset in the control device. If the temperature becomes higher than the above, the power supply to the drying device is stopped, and if the temperature measured by the temperature sensor becomes lower than the second temperature set in the control device in advance, the drying device is stopped. The power supply of the washing machine is started, and the stop and start of the power supply are repeated for a time set as a drying step, so that the drying temperature in the washing machine is maintained at a predetermined temperature by the output from the control device on the washing machine side. The apparatus can be easily controlled, and the drying performance is improved.

Fifthly, the operation time of the drying step can be automatically set by the control device in accordance with the load of the laundry put into the washing machine. Since the drying time is automatically set in proportion to this, the drying time appropriate for the amount of the laundry is reliably set. Also, the data of the load of the laundry determined when performing the washing operation prior to the drying operation can be used for setting the drying operation time, and the data is effective even when the drying device is separated from the washing machine. It can be used.

Sixth, the operation time of the drying step is automatically set by the control device based on the number of inertia pulses of the rotor, so that the drying operation is performed by connecting a separate drying device. , The appropriate drying time can be determined on the washing machine side,
In addition to being able to effectively use the functions of the washing machine, the drying device does not require a control device for determining the drying time, so the drying device does not require a control device or a structure for determining the drying operation time. The structure is simple.

Seventh, a third measured temperature measured by the temperature sensor at the time of starting the power supply to the drying device is stored, and after the third measured temperature is measured, n minutes after the power is supplied. Storing the measured fourth measured temperature, comparing the third measured temperature with the fourth measured temperature, and as a result of the comparison, when the fourth measured temperature is lower than the third measured temperature, or When equal, by displaying an error, when using a commercially available dryer or futon dryer as a drying device,
When the drying unit does not turn on due to an operation error on the user side,
Since this can be detected by the temperature change on the washing machine side, it is possible to prevent the operation from proceeding under the control from the washing machine side while the clothes are not dried.

[0025]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an overall explanatory view showing a state in which a drying device according to an embodiment of the washing machine of the present invention is connected, FIG.

The washing and dewatering tub 4 has a structure in which the opening is opened toward the center of the bottom of the washing and dewatering tank 4 so that warm air is discharged.

A closing member 50 is detachably attached to the hole 49 as shown in FIG. The closing member 50
Is formed of, for example, a transparent member such as transparent plastic so that the inside of the washing and dewatering tub 4 can be viewed.

The lid 7 is provided with an exhaust hole 51 for discharging warm air from inside the washing and dewatering tub 4 in a line with the hole 49.

In FIG. 1, reference numeral 52 denotes a drying device connected to a washing machine.
2a, a heater 53 for generating warm air,
And a fan 54 for sending out the hot air generated by the fan 3. The air duct 55 for guiding the hot air sent from the fan 54 into the washing and dewatering tub 4 is connected to the casing 5.
2 a, and a connection port 55 a that fits into the hole 49 was formed at the tip of the air duct 55.

Various types of the drying device 52 are conceivable. The example shown in FIG. 1 has a built-in dehumidifying mechanism.
A dehumidifier 56 having a cooling water supply mechanism and the like is disposed in the casing 52a on the upstream side of the fan 54, and one end of an intake duct 57 is opened near the dehumidifier 56,
The other end of the intake duct 57 is connected to an exhaust hole 51 formed in the lid 7 of the washing machine.

FIG. 4 shows another example of the drying device 52, which is a semi-circulation type having an exhaust function. A fan 54 is provided on the side of the casing 52a connected to the intake duct 57, and the fan 54 is provided on the side of the air duct 55. A heater 53 was provided, and an exhaust port 58 communicating with the atmosphere was provided on the side wall of the casing 52 at a position near the fan 54. The ventilation duct 55 and the intake duct 57 are formed of, for example, flexible bellows-shaped hoses.

As the drying device 52, a commercially available dryer or a futon dryer can be used in addition to an optional device that is exclusive to the washing machine and can be used. For example, the top cover 6 on the washing machine side can be used. An output terminal 59 for supplying power to the drying device 52 is provided on the back side or the like. As shown in FIG. 5, the output terminal 59 is formed in a commercially available outlet shape so that a commercially available dryer or the like can be connected. A power cord 60 is provided on the side of the drying device 52 so as to be detachably connected to the output terminal 59.

Further, a temperature sensor 61 such as a thermistor for measuring the temperature in the washing machine during a drying operation described later is provided at an appropriate place inside the washing machine, for example, between the outer box 1 and the top cover 6.

FIG. 6 is a control block diagram of such a washing machine.
A temperature sensor 61 and a rotation speed detector 63 for measuring the inertial rotation speed of the rotary wing 3 are connected to the input side of a control device 62 using a microcomputer or the like, which is provided on the front side of the outer case 1, and the output side is dried. Output terminal 5 for power supply to device 52
9 was connected.

In such a washing machine to which the drying device 52 is detachably connected, the control device 62 on the washing machine side includes a washing and rinsing process and a rinsing process which automatically proceeds. Then, a drying step of drying the laundry by supplying warm air into the washing and dewatering tub 4 is set. This drying step includes, for example, a low-speed dehydrating rotation for rotating the washing and dewatering tub 4 at a low speed, a cloth loosening step for rotating the rotary wings 3 and a cloth scraping step for rotating the washing and dewatering tub 4 after the rinsing of the washing step. Was combined.

When the drying process is performed after the washing process as a course operation, the closing member 50 attached to the lid 7 is removed at the start of the washing, and the connection port 55 a at the end of the air duct 55 of the drying device 52 is inserted into the hole 49. And the tip of the intake duct 57 is connected to the exhaust hole 51.
0 is connected to the output terminal 59 of the washing machine, the drying device 52 is connected to the washing machine in advance, and this drying step is selected by an operation from an operation unit provided on the top cover 6 or the like.

Then, the clothes are put into the washing and dewatering tub 4 through the opening 5, and the lid 7 is closed and the operation section is operated to start the washing process, whereby the washing, rinsing and dehydrating processes automatically proceed. I do. At this time, if the drying device 52 is not connected to the hole 49 provided in the lid 7, the transparent closing member 50
The washing condition inside the washing and dewatering tub 4 can be monitored through the.
In this case, since the hole 49 is covered with the closing member 50 as described above, it is possible to prevent dangerous actions such as putting a hand into the hole 49.

After the final dehydration step of the washing operation, power supply from the output terminal 59 to the drying device 52 starts, and the drying device 52 automatically operates to shift to the drying process. In this drying step, the heater 53 and the fan 54 operate. Therefore, the air heated by the heater 53 is supplied into the casing 52 a by the fan 54 through the ventilation duct 55 through the hole 49.
From the washing and dewatering tub 4 and directly hit the laundry inside. Since the air duct 55 is air-tightly connected to the hole 49 by the coupling 59, warm air does not leak into the atmosphere from here.

At this time, on the washing machine side, the washing and dewatering tub 4 rotates at a low speed, and at the same time, the rotary wings 3 alternately and repeatedly rotate, for example, clockwise and counterclockwise alternately. The objects are randomly displaced up, down, left and right and loosened, and subsequently, only the washing and dewatering tub 4 is rotated, for example, alternately left and right, and the laundry stuck to the peripheral wall of the tub is scraped off. When the laundry is replaced, the warm air blows uniformly to all parts of the laundry in the washing and dewatering tub 4. Therefore, drying can be efficiently performed in a short time.
Further, since the hole 49 is opened above the central portion of the washing and dewatering tub 4, warm air is efficiently supplied to each part in the washing and dewatering tub 4.

The hot air that has come into contact with the laundry in the washing and dewatering tub 4 to remove moisture contained in the laundry and become humid is sucked from the exhaust hole 51 into the intake duct 57 and dried.
Return to the inside of the second casing 52a. By forcibly returning the hot air to the drying device 52 in this manner, it is possible to prevent the inside of the washing machine from becoming hot and humid. The humid hot air returned to the drying device 52 is dehumidified by the dehumidifying device 56, heated again by the heater 53, and supplied from the air duct 55 to the washing and dewatering tub 4. By repeating this circulation, the laundry in the washing and dewatering tub 4 is dried.

When the drying device 52 is of the type as shown in FIG. 4, a part of the warm air sucked into the casing 52a by the fan 54 is discharged from the exhaust port 58 to the atmosphere. This can prevent the air in the washing machine from becoming too hot.

During the drying operation, the temperature in the washing machine is measured by a temperature sensor 61 disposed in the washing machine, and if the temperature is equal to or higher than a predetermined temperature which is a first temperature set in the control device 62 in advance. Then, the power supply from the output terminal 59 to the drying device 52 is stopped, the operation of the drying device 52 is stopped, and the supply of hot air is stopped.

When the operation of the drying device 52 is stopped and the temperature measured by the temperature sensor 61 falls below a predetermined temperature, which is a second temperature preset in the control device 62, the output terminal 59 sends the signal to the drying device 52. The power supply is started to start the operation of the drying device 52 to supply hot air. By repeating such power supply and stop, the stop and operation of the drying device 52 are repeated for the set drying operation time, and thereby the drying temperature in the washing machine is maintained at a predetermined temperature.

The setting of the drying operation time can be arbitrarily set by the operation unit on the washing machine side. However, in the case of the course operation in which the drying operation is automatically performed after the washing operation as described above, In order to set the water level and course of the washing operation, the washing operation is performed based on the load of the laundry determined at the start of washing. Thus, if the load is large, the drying time is automatically set to be long, and the drying time suitable for the amount of laundry is set.

The setting of the drying operation time is not limited to the above-described method.
In some cases, only the drying operation is performed. In such a case, the object to be dried is put into the washing and dewatering tub 4, the rotating blades 3 are rotated, and the number of inertial rotation pulses after stopping is detected by the rotation number detector 63. The control device 62 determines the load amount based on this data. The control unit 62 determines the drying operation time according to the load amount, and supplies power to the drying device 52 only during this time.

In this way, a separate drying device 5 is attached to the washing machine.
When 2 is connected to the washing machine and the drying process is selected,
The operation time of the drying process is determined using the washing machine or the control device 62 of the washing machine, and the drying operation is controlled by the control device 62 of the washing machine.

When a commercially available dryer or the like is used as a drying device, only the air duct 55 is connected to the connection port 55.
a and the exhaust hole 51 may not be used, but in such a case, as shown by arrows in FIG. After flowing into the space, the water flows into a gap between the water tank 2 and the outer box 1 and is discharged out of the body through an opening at the bottom of the outer box 1 and the like.

In the above-described embodiment, the structure for connecting the drying device 52 is based on the air duct 55. However, the structure is not limited to this, and although not shown, the air duct 55 is not used. It is also possible to adopt a structure in which the drying device 25 is directly mounted on the lid 7 of the washing machine.

During the drying operation, the temperature in the washing machine rises due to the warm air blown from the drying device 42. If the operation starts normally and is proceeding, as shown in FIG. Regarding the temperature change measured by the sensor 61, the fourth measured temperature measured n minutes later is higher than the third measured temperature measured at the start of operation, and
During the drying operation after the temperature has risen to the set temperature, the heater 53 is turned on and off between the first set temperature and the second set temperature, and the heater 53 is turned on and off between the first set temperature and the second set temperature. The temperature in the washing machine repeatedly rises and falls.

When a commercially available dryer or futon dryer is used as the drying device 52, the user connects the outlet of the drying device 52 to the output terminal 59 of the main body of the washing machine and also turns off the power supply of the drying device 52. Set to “On” or set a timer to set the drying device 5
2 must be set to work.

However, if the operation is started by the output from the washing machine in a state where the above operation is not performed due to an operation error on the user side, the drying device 52 does not operate, so No warm air is supplied, and the operating time set on the washing machine side elapses in this state. As a result, at the end of the driving time, the clothes are not dried at all.

If the operation time set on the washing machine side is longer than the operation time set by the timer on the drying device 52 side, the supply of hot air is stopped during the operation, and The operation ends with drying being in progress, and the clothes are not sufficiently dried.

To cope with this, the present invention stores a third measured temperature measured by the temperature sensor 61 at the start of operation, and further stores a fourth measured temperature measured during power supply n minutes later. The third and fourth measured temperatures are compared. As a result of the comparison, if the fourth measured temperature is higher than the third measured temperature as shown in FIG. 8, the supply of hot air is performed. However, when the third and fourth measured temperatures are equal as shown in FIG. 9, it is determined that hot air is not being supplied, that is, the power of the drying device 52 is not turned on. An abnormal display is made on the display unit of the washing machine.

Immediately after the start of the drying operation, the fourth measured temperature is higher than the third measured temperature as shown in FIG.
Even if it is determined that the power of the drying device 52 is turned on, the temperature when the heater 53 reaches the second set temperature when the heater 53 is turned on is then changed to the third temperature during power supply as shown in FIG.
And the fourth measured temperature measured during power supply n minutes later is stored, and the third and fourth measured temperatures are stored.
When the third measurement temperature is higher than the fourth measurement temperature as a result of the comparison, the time set by the timer of the drying device 52 is timed up, and the time is set by the washing machine. Before the set operation time is over, the operation of the drying device 52 is stopped, it is determined that hot air is not being supplied to the washing machine, and an abnormality display is performed on a display unit or the like of the washing machine.

Thus, if the drying device 52 is not operating properly due to an operation error on the user side, it can be detected at an early stage, and the operation is performed in a state where hot air is not supplied to the washing machine, and the clothes are washed. It can be prevented from being left dry.
