Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an improvement in a fully automatic washing machine.

[0002]

2. Description of the Related Art A conventional washing method is generally a scrubbing method in which a pulsator is fixed by fixing a washing / dehydrating tub and the pulsator is inverted, and the rib on the washing / dehydrating tub hits the clothes. Control the pulsator reversal time. However, according to this washing method, depending on the material of the laundry, the material may shrink, lose its shape, or be severely damaged, so that it cannot be washed. Further, since the water in the water supply was applied only to a certain place in the washing / dehydrating tub, it was not possible to evenly water the laundry during the water supply.

[0003]

According to the above-mentioned prior art, depending on the material of the laundry, laundry which cannot be washed in the washing machine by hand or is washed by a specialist can be washed in the washing machine according to the present invention. . Further, since the water in the water supply was applied only to a certain place to the washing / dehydrating tank, it was not possible to evenly spray the laundry during the water supply. In addition, by rotating the washing / dehydrating tub in the dehydrating direction, it is possible to quickly apply water or detergent solution evenly to the laundry.

[0004]

In order to solve the above-mentioned problems, the fully automatic washing machine according to the invention of claim 1 is provided with a washing / dewatering tub and a pulsator coaxially in a water tub, and the washing is performed by a drive motor and a clutch mechanism. In a fully automatic washing machine in which both the dewatering tank and the pulsator are simultaneously rotated or only the pulsator is rotated independently, and water is supplied to the water tank through the water supply port by turning on the water supply valve,
The washing / dehydrating tub and the pulsator are intermittently rotated simultaneously while water is stored in the aquarium, and the water flow is used to wash or rinse the laundry.

Therefore, according to this structure, the washing / dehydrating tub is rotated with the pulsator intermittently in a state in which water is stored in the washing / dehydrating tub to create a weak water flow which has never existed before, and the water flow is used to wash the laundry. It becomes possible to wash and rinse. As a result, the user can wash the laundry without damaging it as if he was washing it by hand.

In the fully automatic washing machine according to the second aspect of the present invention, the simultaneous rotation of the washing / dehydrating tub and the pulsator and the rotation of only the pulsator in a direction opposite to the rotation direction are alternately executed.
It is characterized in that laundry is washed or rinsed with the water stream. Therefore, according to this structure, in the invention of claim 1, in addition to the intermittent rotation of the washing / dehydrating tub in the dehydrating direction, the pulsator is intermittently rotated in a direction opposite to the dehydrating direction, which is not possible in the conventional case. It is possible to create a weak water flow and wash and rinse laundry with the water flow. As a result, a softer water flow can be created and the laundry can be washed without damage.

According to the fully automatic washing machine of the third aspect of the invention,
A washing / dehydrating tub and a pulsator are coaxially provided in the water tub, and both the washing / dehydrating tub and the pulsator are simultaneously rotated by the drive motor and the clutch mechanism, or only the pulsator is independently rotated, and the water supply valve is turned on. In a fully automatic washing machine in which water is supplied into the aquarium through the water supply port, the washing / dehydrating tub and the pulsator are simultaneously rotated in the water supply at a speed lower than that in a normal dewatering operation to wash the laundry. On the other hand, the feature is that water is supplied while spraying water almost evenly.

Therefore, according to this construction, the washing / dehydrating tub is rotated at a low speed during water supply, so that the laundry is evenly sprinkled with water. As a result, the washing and rinsing steps can be improved.

In the fully automatic washing machine of the fourth aspect of the present invention, the washing / dehydrating tub and the pulsator are coaxially provided in the water tub, and both the washing / dehydrating tub and the pulsator are simultaneously rotated by the drive motor and the clutch mechanism or the pulsator is rotated. In a fully automatic washing machine in which only the water is rotated independently and water is supplied to the water tank through the water supply port by turning on the water supply valve, a detergent is externally applied between the water supply valve and the water supply port. A detergent dissolver that can be charged is provided, and when the detergent is charged, the supplied detergent is turned into a detergent solution according to the water supply when the water supply valve is turned on, and is supplied to the water tank. It is characterized in that the detergent is rotated at a lower speed than at the time of the normal removal operation, and the detergent liquid is applied to the laundry substantially evenly.

Therefore, according to this structure, the washing / dehydrating tub and the pulsator are simultaneously rotated in the water supply at a speed lower than that during the dehydration operation, and the detergent liquid is evenly applied to the laundry. As a result, since the detergent liquid spreads throughout the laundry during water supply, the washing effect can be further improved.

In the fully automatic washing machine of the fifth aspect of the present invention, the washing / dehydrating tub and the pulsator are coaxially provided in the water tub, and both the washing / dehydrating tub and the pulsator are simultaneously rotated or driven by the drive motor and the clutch mechanism. In a fully automatic washing machine in which only the pulsator is rotated independently, and water is supplied to the water tank through the water supply port when the water supply valve is turned on, the washing / dewatering tank and the pulsator are normally operated during water supply. When the water level in the water tank reaches the set water level during the dewatering operation, the washing / dewatering tank and the pulsator are intermittently rotated at the same time to wash or rinse the laundry. It is characterized by that.

Therefore, according to this construction, by rotating the washing / dehydrating tub together with the pulsator at a lower rotation speed than during dehydration, water, detergent liquid, or the like is evenly applied to the laundry and at the set water level intermittently. By rotating the washing and dehydrating tub together with the pulsator, it was possible to wash and rinse with a water flow due to the rotating force. As a result, the washing efficiency can be improved and the same washing as hand washing can be performed in the washing machine.

Further, in the fully automatic washing machine according to the invention of claim 6, after the water level in the water tub reaches a set water level, the pulsator is rotated in the opposite direction in addition to the simultaneous rotation of the washing / dewatering tub and the pulsator. It is characterized in that only the above-mentioned rotation is performed, and the simultaneous rotation of the both and the rotation of only the pulsator are alternately performed for a short time respectively, and the washing or rinsing of the laundry is performed by the water flow. Therefore, according to this configuration, washing efficiency can be improved and a softer water flow can be obtained, so that washing closer to hand washing can be performed.

Reference numeral 20a denotes a detergent dissolver provided between the water supply valve 20 and the water supply port 21. When water flows in through the water supply valve 20, the detergent introduced therein is melted and the water supply port 21 is provided.
It is configured to be supplied to the water tank 2 via. Reference numeral 22 is an outer lid provided on the upper plate of the outer box 1 to open and close the laundry input port 22a.

Reference numeral 23 denotes a control panel provided on the front portion of the upper plate. The panel 23 includes an operation switch group 24 for performing operations for setting the washing machine in various operating states as shown in FIG. A display unit 25 that displays various operating states is provided.

The operation switch group 24 includes a power switch 26, a start key 27 for starting and stopping a washing operation, a washing course selection key 28a, a favorite mode selection key 28b, an end reservation key 28c and a water level setting key 28d. Is included. Reference numeral 29 denotes a control circuit, which is arranged on the lower surface of the control panel 23 and has a circuit configuration shown in detail in FIG.

As shown in FIG. 5, the control circuit 29 is composed of a microcomputer 32 and a switching circuit 35. The drive motor 6 provided with a phase advancing capacitor 31, the mode switching motor 17, the water supply valve 20, and the operation switch group. 24, the display unit 25, the water level sensor 33, and the laundry capacity detection unit 34, and is configured to receive power supply voltage from the AC power supply 30 together with these units.

The operation switch group 24, the water level sensor 33, the capacity detecting section 34, etc. are connected to the microcomputer 32.
The display unit 25, the drive motor 6, the mode switching motor 17, the water supply valve 20 and the like act as an output unit. The fully automatic washing machine according to the present invention is configured as described above, and its operation will be described below.

(Hand Washing Operation I) The hand washing course I executed by the fully automatic washing machine according to the present invention is as follows, which will be described with reference to the flowchart of FIG. 6 and the time chart of FIG. 7. First, the power switch 26 of the control panel 23
Is turned on (A ₁ ), and then the “hand wash course I” is selected (A ₃ , A ₄ ) by operating the course selection key 28 a and the start key 27 is turned on (A ₅ ).

Then, the microcomputer 32 indicates that the "hand wash course I" has been selected and the start key 27
Is detected and a signal is supplied to the water supply valve 20 through the switching circuit 35 to turn on the valve 20 to start water supply (A ₆ ). When the water supply is started, the microcomputer 32 determines the water level in the water tank 2 based on the signal obtained from the water level sensor 33 (A ₇ ), and when the water level reaches the set water level, the water supply valve 20 is turned off, Stop water supply (A ₈ ).

Then, the microcomputer 32 supplies a signal to the mode switching motor 17 to drive the motor 17, and slides the connecting angle 19a from the point A to the point B in the direction of arrow I via the wire 18 (A ₉ ). At this point B, the drain valve 16 cannot be opened, but the clutch lever 10 and the brake lever 15 are in the state shown by the alternate long and short dash line, and the washing tub 4 and the pulsator are simultaneously rotated to switch to the dehydration state (A ₁₀ ). .

Upon completion of the switching of the angle 19a to the point B, the microcomputer 32 causes the switching circuit 3 to operate.
7, the drive motor 6 is intermittently driven in the right (R) direction, and the washing tub 4 and the pulsator 5 are intermittently rotated in the same right (R) direction and intermittently. Create a stream of water (A ₁₁ ). This weak water flow causes the laundry to undergo a washing action similar to hand washing.

(Hand Washing Operation II) This hand washing operation II performs the same steps as the course I until the step (A ₁₀ ) of the completion of the mode switching to the dehydration state in the above course I. Only explained. When the switching to the dehydration state is completed in step A10, the microcomputer 3 is used in the main hand washing course II.
The drive motor 6 is intermittently rotated to the right (R) and the left (L) for a short time as shown in FIG. 8 through the switching circuit 35 by the signal from 2.

As a result, while the drive motor 6 is rotating to the right, both the washing tub 4 and the pulsator 5 are rotated to the right due to the relationship between the clutch lever 10 and the clutch gear 11.
Further, only the pulsator 5 is rotated to the left while the drive motor 6 is rotating to the left. When the drive motor 6 rotates to the left, the clutch lever 10 and the clutch gear 11 do not mesh with each other, so that only the pulsator 5 rotates.

By the above operation, a weak water flow is created in the water tank 2, and the laundry is subjected to the same washing action as hand washing. In either case of the hand washing course I and the course II, when the washing operation is completed, the mode switching motor 17 is further driven according to the instruction of the microcomputer 32 to pull the wire 18, and the connecting angle 19 is moved in the direction of the arrow I. Then, the drain valve 16 is opened and the water in the water tank 2 is drained. Finally, the drive motor 6 is rotated to the right to rotate the washing tub 4 and the pulsator 5 in the same direction to execute the dehydration action.

(Water Supply Operation) In the washing machine according to the present invention, at the time of water supply such as washing or rinsing, the operation shown in the flowchart of FIG. 9 is executed so that water is poured on the laundry on average. First, the power switch 26 is turned on (B ₁ ). Then, if the manual course, set to your preferred mode at your favorite mode selection key 28b and (A _3), to turn on the subsequent start key 27 (B _4).

If it is not the manual course, it is the standard course (B ₂ ), so the start key 27 is turned on next to the power switch 26 (B ₄ ). When the start key is turned on, the microcomputer 32 turns on the water supply valve 20 via the switching circuit 35 (B ₅ ),
Start water supply. Then, the microcomputer 32 supplies a signal to the mode switching motor 17 via the switching circuit 35 to drive the motor 17 to pull the wire 18 and move the connecting angle 19a from the position A to the position B.

At this time, the drain valve 16 has not been opened by the movement of the connecting angle 19a to the position B. When switched to the position B of the coupling angle 19a as described above is completed (B _7), the drive motor 6 is rotated by a signal of the microcomputer 32, a lower rotational speed than in the normal dehydration (e.g. 20 revolutions per minute ) With washing tub 4 and pulsator 5
Are simultaneously rotated in the dehydration direction (clockwise rotation) (B ₈ ). At this time, the water supplied from the water supply valve 20 into the water tub 2 is evenly applied to the laundry as the laundry tub 4 rotates.

When the water level in the water tank 2 reaches the set water level (B ₉ ) while the laundry tub 4 is rotating at a low speed and the laundry is splashed with water, the water level sensor 33 detects this, A signal indicating that the water level has reached the set water level is supplied to the microcomputer 32. Then, the microcomputer 32 cuts off the power supply to the mode switching motor 17 upon receiving the signal, and turns off the motor 17 (B
₁₀ ). As described above, the operation of rotating the washing tub 4 at a low speed and uniformly supplying water to the laundry while supplying water is completed. And
The microcomputer 32 advances the washing machine to the next step (B ₁₁ ).

(Automatic Detergent Water Supply Operation) Next, a water supply operation for automatically adding detergent will be described. This operation is different in that the detergent is put in the detergent dissolver 20a in advance, but is shown in the flowchart of FIG. 9 (water supply operation).
Is substantially the same as In the state where the detergent is put in the detergent dissolver 20a, the power switch 26 of the control panel 23 is first turned on.

In the case of the manual course, the favorite mode is set with the favorite mode selection key 28b, and then the start key 27 is turned on. If it is not the manual course, the start key 27 is turned on next to the power switch 26. When the start key is turned on, the microcomputer 32 causes the water supply valve 20 to pass through the switching circuit 35.
Turn on to start water supply.

The water supplied from the water supply valve 20 at the start of the water supply dissolves the detergent in the detergent dissolver 20a provided in the water supply path to become a detergent liquid, and the water supply port 2 is provided in the washing tub 4.
Supplied from 1. On the other hand, at the same time as or immediately after turning on the water supply valve 20, the microcomputer 32 drives the mode switching motor 17 via the switching circuit 35 and pulls the wire 18 to move the connecting angle 19a to the position A.
To B.

At this time, the drain valve 16 has not been opened. When the switching of the connecting angle 19a to the position B is completed as described above, the signal of the microcomputer 32 causes the drive motor 6 to rotate at a lower rotation speed than that during normal dehydration.
The washing tub 4 and the pulsator 5 are simultaneously rotated (clockwise rotation). With this rotation, the detergent solution is evenly applied to the laundry in the washing tub 4.

As described above, the washing tub 4 rotates at a low speed together with the pulsator 5 and the laundry liquid is sprayed with the detergent liquid (only water is contained when the detergent dissolver 20a is free of detergent). When the water level reaches the set water level, the water level sensor 33 detects this and supplies a signal to the microcomputer 32 indicating that the water level has reached the set water level. Then, the microcomputer 32 cuts off the power supply to the mode switching motor 17 according to the signal, turns off the motor 17 to stop the low speed rotation of the washing tub 4 and the pulsator 5, and advances the washing machine to the next step.

(Handwashing Course I) As shown in the flow chart of FIG. 10, when the power switch 26 of the control panel 23 is turned on in this course, the microcomputer 32 judges whether it is the standard course (C ₂ ). Then
At that time, for example, hand washing course by course selection key 28a is selected _{(C 3) (C 4)} , the flow proceeds to step C5, wait for the operation of the start key 27.

Next, when the start key 27 is turned on, the microcomputer 32 outputs a signal to turn on the water supply valve 20 via the switching circuit 35 (C ₆ ),
Water is supplied to the aquarium 2 from the water supply port 21 (see FIG. 11).
Further, at this time, if the detergent is placed in the detergent dissolver 20a, the detergent liquid is supplied to the water tank 2.

Simultaneously with the start of the water supply, the microcomputer 32 drives the mode switching motor 17 and pulls the wire 18 to move the connecting angle 19a from the position A to the position B.
Move up to At this time, the drain valve 16 has not been opened. When switching of the connection angle 19a is completed (C _7, C _8), simultaneously rotating the washing tub 4 and the pulsator 5 in a lower rotational speed than during drive motor 6 is normal dehydration by a signal of the microcomputer 32 (clockwise) Let (C
₉ ).

With this rotation, the supplied water or detergent liquid is evenly applied to the laundry in the washing tub 4. In this way, when the detergent is applied and the water supply progresses, and the water level reaches a predetermined water level (C ₁₀ ), the water level sensor 33 detects this, and accordingly, the microcomputer 32 supplies power to the water supply valve 20. Cut off supply (C ₁₁ ).

When the water supply is stopped by stopping the power supply to the water supply valve 20, the microcomputer 32 intermittently drives the drive motor 6 to intermittently rotate the washing tub 4 and the pulsator 5 in the same direction to wash the hand with a weak water flow. The process is executed (C ₁₂ ).

When this hand washing process is completed (C
₁₃ ), the microcomputer 32 stops the driving of the drive motor 6 and drives the mode switching motor 17 to further pull the wire 18 and pull the connecting angle 19b in the arrow direction via the connecting angle 19a to move the drain valve 16 to the drain valve 16. Open (C ₁₄ ). The water in the water tank 2 is drained by opening this 16.

Then, when the drainage is completed (C ₁₅ ), the microcomputer 32 rotates the drive motor 6 to rotate the washing tub 4 together with the pulsator 5 at a high speed to execute the dehydration operation. When the dehydration is complete (C _17), and is returned to the operation stop state the mode switching motor 17 stops the driving motor 6 by a signal from the microcomputer 32 returns the wire, closing the drain valve 16 (C ₁₈ ).

Immediately after that, the microcomputer 32 turns on the water supply valve 20 again (C ₁₉ ), starts the water supply, drives the mode switching motor 17 again, and moves the connecting angle 19a from the position A to the position B. The mechanism 9 is switched to the dehydration side (C ₂₁ ). When the switching is completed, the drive motor 6 is rotated by the signal of the microcomputer 32 to rotate the washing tub 4 together with the pulsator 5 at a lower rotation speed than that at the time of dehydration.

As a result, the laundry is sprinkled evenly while rotating at low speed. When the water level reaches a predetermined level (C ₂₃ ), the drive motor 6 is intermittently rotated by a command from the microcomputer 32, and the washing tub 4 and the pulsator 5 are intermittently rotated in the same direction to perform rinsing with a weak water flow ( C ₂₄ ).

(Handwash Course II) This course II is basically the same as the above handwash course I, but differs in one point. Therefore, description of the same operation is omitted, and only different points will be described with reference to FIG. As shown in FIG. 12, in this course, by controlling the drive motor 6 and the clutch mechanism by the command of the microcomputer 32 in the washing process and the rinsing process, simultaneous rotation of the washing tub 4 and the pulsator in the dehydration direction for a short time is performed. Short-time rotation of the pulsator 5 only in the anti-dehydration direction is alternately executed to create a weak water flow, and hand washing and rinsing are performed.

(Standard course) In this course, the standard course is selected in the hand washing course I shown in FIG. 10 (C ₂ ) and the start key is turned on, or the hand washing course is not selected in step C _4. Set when the start key is turned on. In this course, the step operations corresponding to steps C ₁₂ and C ₂₄ of the above hand washing course I are different from those of the hand washing course I, and all other operations are the same. That is, only the differences between the two are as follows.
