[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for both dehydration and washing, in which power between washing and dehydration is switched by utilizing the buoyancy of water.

[0002]

2. Description of the Related Art Conventionally, in a washing machine for both dehydration and washing,
A motor is commonly provided for washing and dehydrating, and the power of this motor is transmitted to a stirring body in a rotating tub at the time of washing, and the washing is performed by rotating the stirring body. And spin them to dehydrate them. Conventionally, such switching of power is performed by a clutch mechanism mainly including a clutch spring provided in a power transmission path from the motor to the agitator and the rotary tank.

[0003] However, clutch springs require precision in the number of turns, inner diameter, and the like.
An electromagnet, a motor, and the like for controlling the operation of the clutch spring are also required, and the structure is complicated and expensive. On the other hand, there are washing machines for both dehydration disclosed in JP-A-57-103690 and JP-A-62-268343.

In these devices, a float chamber is formed at the outer bottom of a rotary tank, and the rotary tank normally engages a passive part with a transmission attached to a shaft that is rotated by a motor together with a stirrer, At the time of washing, water is collected in the non-rotating tub (outer tub) in which the rotating tub is provided together with the inside of the rotating tub, so that the air is sealed in the float chamber and the rotary tub is floated, and the rotating tub is lifted. Separate the passive parts,
The rotational force of the motor is transmitted only from the shaft to the stirring body, not to the rotating tank, and
At the time of dehydration, the water in the above-mentioned rotating tub and the non-rotating tub is discharged, so that the rotating tub descends to bring the passive portion into contact with and engage with the transmission, and the rotational force of the motor is transmitted from the shaft to the rotating tub together with the stirring body. It is transmitted to. According to these, the structure is simple, the precision of the parts is not required so high, and it can be provided at a low cost.

[0005]

However, in the above-mentioned apparatus, it is necessary to secure a large gap above the rotary tub because of the floating of the rotary tub during washing. There was a risk that the laundry would jump out of the machine. In addition, the overall height is increased by the large gap, so that it is difficult to take out the laundry from above. In addition, when the rotating tank descends, it tilts,
Since the rotating force of the motor can be transmitted while being tilted, the rotating tub shakes at the time of spin-drying, and there is also a problem that abnormal vibration is likely to occur.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and its object is not only that the structure is simple and the precision of parts is not so high, but also that the laundry is easily ejected or hardly taken out. An object of the present invention is to provide a washing machine that is capable of switching a required power without becoming uncomfortable and easily causing abnormal vibration during spin-drying.

[0007]

In order to achieve the above object, the present invention provides a spin-drying and washing machine according to the present invention, which comprises a rotating tub and a stirrer disposed inside the spinning tub, and rotates the stirrer during washing. washing and Te, in the those adapted to the dehydration of the rotary drum is rotated together with the agitator during dehydration, the times
The transfer tank is provided so as not to be able to float and descend, and the rotation of the stirring body is performed.
The motor that is the driving source for the rotation and rotation of the rotating tub, and the stopper
A shaft that is provided in a state, is rotated by the motor, and fixes the stirring body, and a position between the rotating tank and the stirring body.
And float along the shaft around the shaft,
A clutch float which is fitted so as to be able to be lowered, connects the shaft and the rotating tub during normal and dehydration , and floats on water accumulated around the shaft during washing to disconnect the shaft from the rotating tub. It is characterized by.

In this case, it is preferable that the clutch float is made to rotate integrally with the shaft and float along the shaft by engagement of the concave and convex portions provided on the outer peripheral portion of the shaft and the inner peripheral portion of the clutch float. The external teeth provided on the clutch float and the internal teeth provided on the rotary tub side may be engaged and disengaged to connect and disconnect with the rotary tub.

The external teeth of the clutch float may be formed in a tapered shape tapering in the direction of the internal teeth on the side of the rotary tub. It is preferable that the diameter is set to be smaller than the diameter of the root circle diameter at the entrance of the side internal teeth. Further, the clutch float may be formed of a foamed plastic having a large number of cells inside,
Alternatively, it may have an air chamber.

On the other hand, in the dehydrating the washing machine of the present invention, with disposing the rotating tub to a non-rotating vessel, it floats in water washing濯時connecting the rotating tub to a non-rotating vessel, during normal and dehydration Non-rotating float that breaks the connection around the shaft
It is also characterized by being fitted and provided.

In this case, the non-rotating float is provided so as to be floatable by the engagement of the concave and convex portions provided on the non-rotating tank side and the non-rotating float and to be always stopped by the non-rotating tank. It is preferable to connect and disconnect the rotating tub by engaging and disengaging the provided teeth with the teeth provided on the rotating tub side. Further, those rotating vessel was made to the water the dehydrated opening has at the top only, in the bottom water channel formed over the drain outlet of the external non-rotating vessel through the central portion of the bottom from the interior of the rotary tub during the washing In this case, it is preferable to dispose a clutch float in the waterway.

An output generating means for generating different outputs according to the vertical position of the clutch float at the time of washing and spin-drying is provided, and the vertical position at the time of washing and spin-drying of the clutch float is determined from the output of the output generating means. It is preferable to provide control means for controlling the operation of the vehicle. In this case, it is preferable that the output generating means generates an output corresponding to the vertical position of the clutch float during washing and dehydration based on the load of the motor. The motor load includes the motor drive current, the applied voltage, and the number of revolutions.

The control means may reverse the motor for a very short period or rotate the motor at a reduced speed when it is determined that the vertical position of the clutch float during washing and spin-drying is inaccurate. It is better to repeat the above several times. In addition, the control means may perform control to notify an abnormality when it is determined that the vertical position during washing and dehydration of the clutch float is incorrect.

[0014]

According to the above-mentioned means, the switching of the required power between the washing and the dehydration is performed by the floating and lowering of the clutch float provided around the shaft, but not by the floating and lowering of the rotary tub. Therefore, it is not necessary to secure a large gap above the rotary tub, and it is also possible to prevent the rotation force of the motor from being transmitted when the rotary tub is inclined.

In this case, the clutch float is configured to rotate integrally with the shaft and float along the shaft by engagement of the concave and convex portions provided on the outer peripheral portion of the shaft and the inner peripheral portion of the clutch float. Power can be reliably transmitted from the shaft to the clutch float, while allowing the clutch float to float and descend along the shaft.

In the clutch float, the clutch float is connected to and disconnected from the rotary tub by engagement and disengagement of the external teeth provided on the clutch float and the internal teeth provided on the rotary tub side. Power can be reliably transmitted and shut off from the rotary tank to the rotary tank.

Furthermore, in the clutch float in which the external teeth are formed in a tapered shape tapering in the direction of the internal teeth on the rotating tank side,
The power transmission from the clutch float to the rotary tank and the switching of the disconnection state can be smoothly performed.
In particular, in this case, if the size of the tip circle diameter of the tip part of the clutch float outer teeth is set smaller than the size of the root circle diameter of the inlet part of the rotating tub side inner teeth, the state can be switched more smoothly. I can do it.

When the clutch float is made of foamed plastic, the floating of the clutch float can be improved. Even if the clutch float has an air chamber, the floating of the clutch float can be improved.

Meanwhile, with disposing the rotating tub to a non-rotating vessel, it floats in water washing濯時connecting the rotating tub to a non-rotating vessel, normal and detent float around the shaft to break the connection to the dehydration in those equipped fitted inserted in the can be reliably performed by detent also float the rotating tub of the washing.

In this case, the non-rotating float is provided so as to be floatable by the engagement of the concave and convex portions provided on the non-rotating tank side and the non-rotating float and is always stopped by the non-rotating tank. The connection and disconnection with the rotary tub by the engagement and disengagement of the provided teeth with the teeth provided on the rotary tub side. , Can be reliably released.

[0021] Also, as the rotating tub has a dewatering openings on the top only, to water the water channel formed toward the bottom drain port of the external non-rotating vessel through the central portion of the bottom from the interior of the rotary tub during the washing With the clutch float installed in the water channel, while saving water usage,
The required power can be switched between washing and dehydrating.

An output generating means for generating different outputs according to the vertical position of the clutch float at the time of washing and spin-drying is provided, and the vertical position at the time of washing and spin-drying of the clutch float is determined from the output of the output generating means. In such a configuration, the operation according to the actual vertical position of the clutch float at the time of washing and dehydration can be performed.

In this case, the output generating means generates an output in accordance with the vertical position of the clutch float during washing and dehydration in accordance with the drive current of the motor, the applied voltage, and the load such as the number of revolutions. In such a case, the difference between the vertical position of the clutch float at the time of washing and at the time of dehydration is clearly shown, so that the determination of the vertical position of the clutch float can be performed more reliably.

In the case where the vertical position of the clutch float is determined to be incorrect at the time of washing and spin-drying of the clutch float, the motor is inverted or rotated at a reduced speed. Can be corrected correctly. In particular, in that case,
By repeating such control a plurality of times, the position of the clutch float can be corrected more correctly.

When it is determined that the vertical position of the clutch float during washing and dehydration is inaccurate, the abnormality is notified. In this case, the vertical position during washing and dehydration of the clutch float is incorrect. The user can be more surely notified of the fact.

Here, a support plate 38 is mounted on the flange 36 of the outer shaft 28 and attached by a plurality of bolts 39. The rotary tank is housed in the outer tank 5 on the support plate 38. The inner tank 40 is placed and attached with a plurality of bolts 41. Holes 42 and 43 are formed in the center of the bottom of the support plate 38 and the inner tank 40.
A ring portion 44 formed at the upper end of the outer shaft 28 is located in each of the shafts 2 and 43, and an upper portion of the shaft 24 protruding upward from the ring portion 44 is located in the inner tank 40.

A clutch float 45 is fitted around the upper portion of the shaft 24. This clutch float 4

Are formed in large numbers as shown in FIG.

On the other hand, external teeth 48 are formed on the outer periphery of the upper part of the shaft 24 above the clutch float 45 in the upper part in the axial direction, and the internal teeth 46 of the clutch float 45 mesh with the external teeth 48. And have a serrated joint structure. The ring portion 44 of the outer shaft 28 has an inner tooth 49 formed on the inner periphery thereof. The outer tooth 47 of the clutch float 45 is meshed with the inner tooth 49 so that the clutch float 4
5, the shaft 24 is connected to the inner tank 40 via the clutch float 45. The ring portion 44 of the outer shaft 28 also has a drainage hole 44a formed at the lowermost portion on the peripheral side. A stirrer 50 housed at the bottom of the inner tank 40 is attached and fixed to the upper end of the shaft 24 with a screw 51.

As shown in FIG. 7, a plurality of small water holes 52 are formed around the hole 42 of the support plate 38.
4, the water guide cover 55 is connected to the bottom of the outer tub 5 by a plurality of bolts 57 via a seal 56. By communicating with the first drain port 58 formed in the inner tank 40, a water channel 59 is formed from the inside of the inner tank 40 to the first drain port 58 of the outer tank 5 through the central portion of the bottom portion. The clutch float 45 and the non-rotating float 32 are located at the same position.

An air trap 60 for detecting a water level is arranged in parallel with the first drain port 58 of the outer tub 5, and these are communicated with a drain hose 62 via a drain valve 61.
In addition, a second drain port 63 is formed at the bottom corner of the outer tub 5 opposite to the first drain port 58 (left side in FIG. 2) so as to directly communicate with the drain hose 62 (omitted). are doing.

Further, the inner tub 40 has a large number of dewatering holes 64, which are openings for dewatering, formed only in the upper end portion, for example, in a horizontal line, and a balance ring 65 is provided in the inner portion thereof for passing water for dewatering. Installed with a gap in between. Further, a ring-shaped tank cover 66 is attached to the upper end of the outer tank 5, and a top cover 67 is attached to the uppermost part of the outer box 1 above it. Inside the top cover 67, a control device 68 as a control means composed of, for example, a microcomputer is provided at a front portion, and a water supply device 69 mainly including a water supply valve 69a is provided at a rear portion.

Now, in the case of the configuration as described above,
At the time of washing, first, water is supplied from the water supply device 69 into the inner tub 40 under the control of the control device 68. This inner tank 40
The water supplied from the inside of the inner tank 40 passes through the small water passage 52 of the support plate 38, the inside of the seal ring 53, the inside of the water guide cover 55, that is, the inside of the water passage 59, and further, the first drain port of the outside tank 5. 5
8 in order to reach the drain valve 61 in the closed state, from which the water level is sequentially raised to fill the waterway 59, and
The water is stored up to the set water level in the inner tank 40.

As a result, the non-rotating float 32 and the clutch float 45 float in the water channel 59 as shown in FIG. As a result, the non-rotating float 32 causes the lower teeth 33 to
While the upper teeth 34 are meshed with the teeth 35 of the outer shaft 28,
7, the outer shaft 28 is connected to the outer tank 5, and the inner tank 40 attached to the outer shaft 28 via the support plate 38 is connected. It is stopped.

On the other hand, the clutch float 45 is
With the external teeth 47 of the shaft 24 being engaged.
Is disengaged from the inner teeth 49 of the outer shaft 28, the connection with the inner tank 40 is released, and the connection between the shaft 24 and the inner tank 40 is released.

Therefore, at this time, the rotational force of the motor 13 transmitted to the shaft 24 is not transmitted to the inner tank 40, but is transmitted only to the stirring body 50 fixed to the shaft 24, and thus the stirring body 50 Only rotate. By the rotation of the stirrer 50, the laundry put in the inner tub 40 in advance is stirred with water, and washing is performed. or,
At this time, the inner tub 40 continues to be prevented from rotating by the non-rotatable float 32, so that the so-called co-rotation with the stirrer 50 is prevented, so that the stirring force of the stirrer 50 effectively acts on the laundry and water. Play.

On the other hand, at the time of dehydration, first, the drain valve 61 is opened, so that the water in the inner tub 40 is discharged from the water channel 59 through the drain hose 62. Thereby, as shown in FIG. 1, the clutch float 45 descends, and the detent float 32 also descends. Therefore, clutch float 4
5 returns to a state in which the external teeth 47 mesh with the internal teeth 49 of the outer shaft 28 while the internal teeth 46 are meshed with the external teeth 48 of the shaft 24, and returns to the connection state with the inner tank 40,
Then, the state returns to the state where the connection with the inner tank 40 is established.

The non-rotatable float 32 returns the upper teeth 34 from the teeth 37 of the outer shaft 28 and only engages the lower teeth 33 with the teeth 35 of the outer tub 5. The connection with the tank 5 is released, and the inner tank 40 is released from the connection with the outer tank 5 to return to a freely rotatable state.

Thus, at this time, the rotational force of the motor 13 transmitted to the shaft 24 is transmitted to the agitator 50 and also to the inner tank 40 via the clutch float 45, and thus the inner tank together with the agitator 50. 40 is rotated. Due to the rotation of the inner tub 40, water is squeezed out of the laundry in the inner tub 40 by centrifugal force, and the squeezed water rises up the inner peripheral surface of the inner tub 40 to form a dewatering hole 64 at the upper end. Further, the water discharged from the dehydration hole 64 is received by the inner peripheral surface of the outer tub 5 and flows down the inner peripheral surface of the outer tub 5 to form the second drain port 63. From the machine through a drain hose 62. In addition, in the case of this configuration, the braking of the rotation of the inner tank 40 is performed by, for example, performing power generation braking of the motor 13.

As described above, according to the present construction, the switching of the required power between the washing and the spinning is performed by the clutch float 45 provided around the shaft 24 rotated by the motor 13.
This is not performed by a clutch mechanism mainly composed of a clutch spring as in the prior art, nor is it performed by floating and lowering of the inner tank 40.

Therefore, not only is the structure simple and the parts precision is not so high, but also it is not necessary to secure a large gap above the inner tub 40, and the laundry is ejected from the gap during dehydration. Also, it is possible to solve the problem of difficulty in taking out the laundry due to an increase in the overall height. In addition, in this case, the inner tank 40 is
Is not fixed to the flange 36, and does not generate a tilt like a conventional floating object, and the rotational force of the motor 13 is not transmitted while being tilted. Vibration, especially abnormal vibration, can be eliminated.

Further, in the case of the above configuration, the clutch float 45 is provided with external teeth 48 provided on the outer peripheral portion of the shaft 24.
By engaging the concave and convex portions of the internal teeth 46 provided on the inner peripheral portion of the clutch float 45, the clutch float 45 rotates integrally with the shaft 24 and floats along the shaft 24. Power can be reliably transmitted from the shaft 24 to the clutch float 45 while allowing the clutch float 45 to float and descend. In this case, the engagement between the shaft 24 and the clutch float 45 may be replaced with a non-circular portion such as a D-shaped section and a hole having the same shape as the hole instead of the teeth 48 and 46.

The clutch float 45 is connected to and disconnected from the inner tank 40 by engaging and disengaging the external teeth 47 provided on the clutch float 45 and the internal teeth 49 provided on the outer shaft 28 on the inner tank 40 side. By doing so, the transmission and disconnection of power from the clutch float 45 to the inner tank 40 can be performed reliably and in a short time only by the movement of the tooth pitch. On the other hand, in the above configuration, the inner tub 40 is connected to the outer tub 5 by floating in water at the time of washing, and the non-rotating float 32 that disconnects the connection during normal and dehydration is provided around the shaft 24.
By equipped with fitted can be reliably performed by detent also float of the inner tub 40 during washing.

In this case, the non-rotatable float 32 is floatable by the engagement of the concave and convex portions of the teeth 35 provided on the outer tub 5 and the lower teeth 33 provided on the non-rotatable float 32 and is constantly restrained by the outer tub 5. And the upper and lower teeth 34 provided on the non-rotating float 32 and the teeth 37 provided on the outer shaft 28 are engaged with and disengaged from the inner tub 40, whereby the rotation is prevented. Stop float 32
The suspension and release of the inner tank 40 can be surely performed while allowing the floating and descending of the inner tank 40.

[0050]

The inner tub 40 has a dewatering hole 64 only at the upper portion, and the inner tub 40 passes through the center of the bottom from the inner tub 40 during washing.
By storing water in the water channel 59 formed over the first drain port 58, water is not stored in the outer tub 5, that is, washing can be performed while saving the amount of water used. Clutch float 4 in the waterway 59
By arranging the 5 and the non-rotating float 32, it is possible to switch the required power between washing and dehydration without impairing the water saving effect.

As shown in FIG. 9, the inner tub 40 is provided with dehydration holes 64 not only in the upper part but also in the entire peripheral part, and the formation of the water channel 59 and the second drainage port 63 is stopped, so that the Even in the case where water is stored from the inner tank 40 to the outer tank 5, the clutch float 45 and the detent float 32 can be provided in the same manner as described above, and can perform the switching function as described above.

As shown in FIG. 10, the clutch float may be a clutch float 72 in which the outer teeth 70 are tapered in the direction of the inner teeth 71 of the outer shaft 28. In particular, in this case, The transmission of power to the outer shaft 28 and the switching of the cutoff state can be smoothly performed.

Further, in this case, the dimension D1 of the tip circle diameter at the tip of the external teeth 70 of the clutch float 72 is determined to be smaller than the dimension D2 of the root circle diameter at the entrance of the internal teeth 71 of the outer shaft 28. As a result (D1 <D2), the transmission of the power from the clutch float 72 to the outer shaft 28 and the switching of the state of disconnection can be performed more smoothly. Note that FIG.
0, the internal teeth 71 of the outer shaft 28 also have the clutch float 72
3 shows a tapered shape similar to the external teeth 70 of FIG.

In addition, the clutch floats 45 and 72 and the detent float 32 are made of a foamed plastic having a large number of air bubbles therein, so that the floatability can be further improved. In this case, non-rotating float 3
2, as shown in FIG. 11, a hollow sealing ring 73 is attached with a screw 74 so that an air chamber 7 is externally provided.
5 may be provided. As shown in FIG. 12, the detent float and the clutch float may be hollow seal type detent floats 76 and clutch floats 77, and may have an air chamber 78 therein. Even so, the floating performance can be improved.

On the other hand, as shown in FIG. 13, the motor 13 has a stator base 79 made of plastic directly mounted on the boss 7 of the outer tub 5 together with the upper bracket 9 by means of bolts 80. The lower bracket 28 may be made unnecessary by providing a configuration in which the lower portion of the lower bracket 28 is supported via the lower ball bearing 26. In this case, a bush 81 made of, for example, aluminum or the like having a smaller thermal deformation rate than plastic is interposed, for example, by insert molding at a portion in contact with the lower ball bearing 26 of the stator base 79, thereby holding the lower ball bearing 27. It can be done reliably.

14 to 16 show a second embodiment of the present invention. In this case, FIG.
As shown in the figure, a control device 68 composed of a microcomputer has a switch input unit 8 composed of various operation switches.
2 and a lid switch 8 for detecting the opening and closing of a lid provided on the top cover 67.
3, a lid open / close detection signal is input, and the inner tank 40
A water level detection signal is input from a water level sensor 84 for detecting the water level in the inner or outer tub 5 through the air trap 60, and the clutch float 45 (7
In this case, a current detection signal is input from the current sensor 85 as an output generating means for generating different outputs according to the vertical position of (2, 77) by, for example, the load of the motor 13.

Based on these inputs and the control program stored in advance, the control device 68
A drive control signal is given to a display unit 86 composed of various display devices, a water supply valve 69a of the water supply device 69, the motor 13, the drain valve 61, and a drive circuit 88 for driving a buzzer 87 as an abnormality alarm. Hereinafter, the control contents of the control device 68 will be described.

As shown in FIG. 15, at the beginning of the operation (start) of the operation, the control device 68 initializes a count value "N" for the occurrence of an abnormality in the vertical position of the clutch float 45 (step A1). ). Next, washing, especially "washing", is started (step A2). In this situation, whether or not the drive current of the motor 13 is equal to or less than a predetermined value, for example, 3.5 [A] is determined by an input from the current sensor 85. Is determined (step A3).

Here, the drive current of the motor 13 at the time of "washing" differs depending on the vertical position of the clutch float 45.
That is, if the clutch float 45 floats on the water at the time of “washing” and is properly separated from the internal teeth 49 of the outer shaft 28, the inner tank 40 is not rotated, and only the agitator 50 is rotated. The load is small, and a drive current of 3 [A] flows through the motor 13 as shown in FIG.

On the other hand, the clutch float 45 during "washing" is caused by the attachment of lint, sand or other foreign matter.
Is not properly separated from the internal teeth 49 of the outer shaft 28,
Since not only the stirrer 50 but also the inner tank 40 is rotated, the load of the motor 13 is large, and a drive current of 4 A or more flows through the motor 13 as described above.

The current sensor 85 detects these currents and inputs them to the control device 68. The control device 68 determines that the drive current of the motor 13 at the time of "washing" is 3.5 from the input.
The vertical position of the clutch float 45 is determined by determining whether it is equal to or less than [A]. In this case, if it is 3.5 [A] or less, the clutch float 4 is determined.
5 is correctly determined to be at the upper position, and if it exceeds 3.5 [A], the clutch float 45 is erroneously determined to be at the lower position.

If it is determined in step A3 that the drive current of the motor 13 is equal to or less than 3.5 [A] (the clutch float 45 is correctly located at the upper position), the "washing" is continued. (Step A4), 3.5
[A] If it is determined that it is not less than (the clutch float 45 is erroneously located at the lower position), the motor 13 is compared with, for example, a normal 1.5-second energization-0.7-second interruption pattern,
Inversion is performed in an extremely short period pattern of 0.4 second conduction-0.3 second interruption (step A5).

The reversal of the extremely short cycle of the motor 13 causes vibration to be applied to the clutch float 45. If the cause of the abnormality in the vertical position of the clutch float 45 is normal, the cause is removed. The position of the float 45 can be corrected correctly.

After step A5, the control device 68 adds "1" to the count value "N" for the occurrence of an abnormality in the vertical position of the clutch float 45 (step A5).
6) Then, it is determined whether or not the count value “N” has reached a predetermined value, for example, “3”, that is, whether or not the abnormality in the vertical position of the clutch float 45 has been counted three times (step A7). It returns to step A3. Then, even in the returning step A3, the driving current of the motor 13 is 3.
If it is determined that it is not less than 5 [A] (the clutch float 45 is erroneously located at the lower position), steps A5 to A
7. Repeat A3. And step A during the repetition
If it is determined in step 7 that the count value "N" has become "3" (the motor 13 has been rotated three times in a very short cycle to correctly correct the position of the clutch float 45), the buzzer 87 is operated. An abnormality is notified (step A8).

On the other hand, before the count value "N" becomes "3" in step A7, the drive current of the motor 13 is 3.5 [A] or less in step A3 (the clutch float 45 is correctly positioned at the upper position). If there is), step A
4 and then perform a “rinse” (step A
9). In this case, the above-described control is not performed in “rinse”, but may be performed.

After that, the control device 68 starts dehydration (step A10). Here, after that, similarly to step A1, the control device 68 initializes the count value "N" for the occurrence of abnormality in the vertical position of the clutch float 45 as in step A1. Then, it is determined whether or not the drive current of the motor 13 is a predetermined value, in this case, 3.5 [A] or more based on an input from the current sensor 85 (step A12).

Also during this "dehydration", the drive current of the motor 13 differs depending on the vertical position of the clutch float 45, that is, if the clutch float 45 descends and meshes properly with the internal teeth 49 of the outer shaft 28. Since the inner tank 40 is rotated together with the stirrer 50, the load of the motor 13 is large, and the motor 13 has a load of 4 [A] as shown in FIG.
Drive current flows. On the other hand, the clutch float 45 does not drop sufficiently or at all due to the adhesion of the lint, sand or other foreign matter, and the internal teeth 4 of the outer shaft 28 do not fall.
9 does not rotate, the inner tank 40 is not rotated, and only the stirring body 50 is rotated, so that the load of the motor 13 is small. Flows.

Therefore, also in step A12, the motor 13
By determining whether or not the drive current of the clutch float 45 is equal to or more than 3.5 [A], the vertical position of the clutch float 45 is determined. In this case, if it is 3.5 [A] or more,
It is determined that the clutch float 45 is correctly located at the lower position, and if it is less than 3.5 [A], the clutch float 45 is determined.
Is erroneously determined to be at the upper position.

In step A12, the motor 13
Is determined to be equal to or more than 3.5 [A] (the clutch float 45 is correctly located at the lower position).
"Dehydration" is continued (step A13),
If it is determined that it is not more than 3.5 [A] (the clutch float 45 is erroneously located at the upper position), the motor 13 is energized for, for example, 0.4 seconds-0.3 as in the step A5.
Invert in an extremely short period pattern of second power interruption (step A1)
4).

Due to the extremely short cycle reversal of the motor 13, the clutch float 45 is vibrated in the same manner as described above. If the cause of the abnormality in the vertical position of the clutch float 45 is normal, it is removed. By removing it, the position of the clutch float 45 can be corrected correctly.

Further, the control device 68 determines in step A14
Are followed by steps A15 and A similar to steps A6 and A7.
After 16, the process returns to step A12. Then, even in the returning step A16, the drive current of the motor 13 becomes 3.
If it is determined that it is not more than 5 [A] (the clutch float 45 is erroneously located at the upper position), steps A14 to A14 are executed.
A16 and A12 are repeated. Then, if it is determined in step A16 during the repetition that the count value “N” has become “3”, the flow proceeds to step A8 to activate the buzzer 87 and notify the abnormality.

On the other hand, in step A16, the count value "N"
Before the value becomes “3”, the drive current of the motor 13 is equal to or more than 3.5 [A] in step A12 (the clutch float 4).
5 is correctly located at the lower position), the process proceeds to step A13, and then the operation is terminated.

By performing such control, the operation according to the actual vertical position of the clutch float 45 at the time of washing and dehydration can be performed. In this case, the clutch float 45
Output means for determining the vertical position of the motor 1
3 (in this case, drive current), the clutch float 4 during washing and spin-drying.
Since the difference between the vertical positions of the clutch float 5 is clearly shown, the determination of the vertical position of the clutch float 45 can be made more reliably.

When it is determined that the vertical position of the clutch float 45 at the time of washing and spin-drying is incorrect, the position of the clutch float is reduced by the vibration effect of reversing the motor 13 for a very short period. Can be corrected correctly. In particular, in such a case, by repeating such control a plurality of times, the clutch float 4
5 can be corrected more correctly.

When it is determined that the vertical position of the clutch float 45 at the time of washing and dehydrating is inaccurate, the abnormality is notified so that the clutch float 45 can be moved vertically at the time of washing and dehydrating. The user can be more reliably notified that the position is incorrect.

FIGS. 17 to 19 show a third embodiment of the present invention. In this embodiment, different outputs are output to the motor 13 depending on the vertical position of the clutch float 45 (72, 77) during washing and spin-drying. A voltage sensor 89 is used as an output generating means for generating a load amount, instead of the above-described current sensor 85, and the output (voltage detection signal) of the voltage sensor 89 is output from the control device 6.
8 is input. This is because the motor 13
It utilizes an inverter motor that changes its rotation speed by changing the applied voltage.

In this case, the voltage sensor 89
Step B3 instead of Step A3 by input from
Then, it is determined whether the detected voltage value is equal to or less than a predetermined value, for example, 80 [V]. In step B12 instead of step A12, it is determined whether the detected voltage value is equal to or more than a predetermined value, for example, 80 [V]. Make a judgment.

In this case, if the clutch float 45 floats on the water at the time of "washing" and is properly separated from the internal teeth 49 of the outer shaft 28, the inner tank 40 is not rotated and only the agitator 50 is rotated. The load of the motor 13 is small, and a voltage of 70 [V] can be applied to the motor 13 as shown in FIG. On the other hand, if the clutch float 45 is not correctly disengaged from the internal teeth 49 of the outer shaft 28 at the time of “washing”, not only the agitator 50 but also the inner tank 40 is rotated, so that the load of the motor 13 is reduced. As described above, it is necessary to apply a voltage of, for example, 90 [V] to the motor 13 as described above.

Thus, in step B3, the vertical position of the clutch float 45 is determined by determining whether or not the applied voltage to the motor 13 is 80 [V] or less. V] or less, it is determined that the clutch float 45 is correctly located at the upper position, and
If it exceeds [V], the clutch float 45 is erroneously determined to be at the lower position.

At the time of "dehydration", the clutch float 45
Is lowered and meshes properly with the internal teeth 49 of the outer shaft 28, the inner tank 40 is rotated together with the agitator 50, so that the load of the motor 13 is large, and as shown in FIG. Needs to be applied with a voltage of 90 [V]. On the other hand, if the clutch float 45 does not drop sufficiently or at all and does not mesh with the internal teeth 49 of the outer shaft 28, the inner tank 40 is not rotated and only the agitator 50 is rotated. The load of the motor 13 is small.
For example, a voltage of 70 [V] is applied to 3 as described above.

Therefore, in step B12, the vertical position of the clutch float 45 is determined by determining whether or not the voltage applied to the motor 13 is 80 [V] or more. V] or more, it is determined that the clutch float 45 is correctly located at the lower position.
If it is less than 0 [V], the clutch float 45 is erroneously determined to be at the upper position. Other steps B1, B2, B4-B11, B13-B16
Are steps A1, A2, A4-A11, A13-A1
6. Therefore, the same operation and effect as described above can be obtained.

FIGS. 20 to 23 show a fourth embodiment of the present invention. In this case, different outputs are output to the motor 13 depending on the vertical position of the clutch float 45 (72, 77) during washing and spin-drying. As an output generating means for generating a load, a rotation speed sensor 90 is used instead of the above-described voltage sensor 89, and the output (voltage detection signal) is input to the control device 68.

In this case, the rotation speed sensor 9
In step C3, which replaces steps A3 and B3 with an input from 0, it is determined whether or not the required time from when the rotation of the motor 13 starts to reach the value of R1 is 3.5 [seconds] or less. In step C12, which replaces steps A12 and B12, the time required from the start of rotation of the motor 13 to the time when the rotation speed reaches the value of R2 is 20.
It is determined whether or not [sec] or more.

In this case, if the clutch float 45 floats on the water at the time of "washing" and is properly separated from the internal teeth 49 of the outer shaft 28, the inner tank 40 is not rotated and only the agitator 50 is rotated. The load on the motor 13 is small, and the required time from the start of rotation of the motor 13 to the rotation speed reaching the value of R1 is 3 [seconds] as shown in FIG. On the other hand, at the time of “washing”, the clutch float 45 is moved to the outer shaft 2.
If the stirrer 5 is not properly separated from the inner teeth 49 of the stirrer 8,
In addition to rotating the inner tank 40, the motor 13
The time required from the start of rotation to the time when the number of rotations reaches the value of R1 is, for example, 4 seconds as described above.

Therefore, in step C3, it is determined whether or not the time required when the rotation speed of the motor 13 has reached the value of R1 from the start of rotation of the motor 13 is not more than 3.5 [seconds]. The vertical position of the clutch float 45 is determined. In this case, if it is 3.5 [sec] or less, it is determined that the clutch float 45 is correctly located at the upper position.
If it exceeds 3.5 [seconds], the clutch float 45 is erroneously determined to be at the lower position.

Further, at the time of “dehydration”, the clutch float 45
Is lowered and meshes properly with the internal teeth 49 of the outer shaft 28, the inner tank 40 is rotated together with the agitator 50, so that the load of the motor 13 is large. The time required for R to reach the value of R2 is shown in FIG.
As shown in FIG. On the other hand, the clutch float 45 does not drop sufficiently or at all,
If the inner teeth 49 of the outer shaft 28 are not meshed, the inner tank 40 is not rotated, and only the agitator 50 is rotated. Therefore, the load of the motor 13 is small. Is more than the above, for example, 10 seconds.

Therefore, in step C12, it is determined whether or not the required time when the rotation speed of the motor 13 reaches the value of R1 from the start of rotation of the motor 13 is not less than 20 [seconds]. The vertical position is determined. In this case, if it is 20 [sec] or more, it is determined that the clutch float 45 is correctly located at the lower position.
If it is less than [seconds], the clutch float 45 is erroneously determined to be at the upper position.

The other steps C1, C2, C4
To C11 and C13 to C16 are steps A1, B1, and A
2, B2, A4-A11, B4-B11, A13-A1
6, B13 to B16, so that the same operation and effect as described above can be obtained.

FIG. 24 shows a fifth embodiment of the present invention. In this case, in step D5 instead of steps A5, B5 and C5, the motor 13 is switched to the normal 145-180.
[Rpm] deceleration from the washing rotation speed, for example, 70 to
Rotation is performed at a rotation speed of 100 [rpm].
In step D14 instead of 4, B14 and C14, the motor 13 is decelerated from the normal spinning rotation speed, and
By rotating the clutch float 45 at a rotation speed of 100 [rpm], the outer teeth 47 of the clutch float 45 are easily detached from the inner teeth 49 of the outer shaft 28 in step D5, and the outer teeth 47 are shifted in step D14. It is easy to mesh with the internal teeth 49 of the outer shaft 28.

Accordingly, even when the vertical position of the clutch float 45 at the time of washing and spin-drying is incorrect, the position can be correctly corrected.
In this case, the determination in steps D3 and D12 is the same as in steps A3 and A12, but may be the same as in steps B3 and B12 or steps C3 and C12, respectively.

However, these other steps D1,
D2, D4, D6-D11, D13, D15, D16
Are steps A1, B1, C1, A2, B2, C2, A
4, B4, C4, A6-A11, B6-B11, C6-
C11, A13, B13, C13, A15, B15, C
15, A16, B16, and C16, so that
The same operation and effect as described above can be obtained. In addition, the present invention is not limited only to the embodiment described above and shown in the drawings, and can be implemented with appropriate modifications without departing from the scope of the invention.
