The present invention relates to a complex washing machine, and more specifically, to increase the washing power by changing the driving method to reduce damage and twist of the laundry, to reduce the amount of detergent and water, and to save the washing time.

In general, a washing machine is a device that automatically washes laundry. The washing machine is divided into a pulsator type washing machine which washes largely in an inner tank and an outer tank, and a drum type washing machine which washes laundry in a state in which the inner tank and an outer tank are laid down. In the washing machine, an outer tub (also called a tub) 2 is supported by a plurality of supports 3 inside the main body 1, as shown in FIG. 1 of the accompanying drawings, and an inner tub (also referred to as a washing tub) inside the outer tub. (4) is rotatably installed, and a pulsator (5) is rotatably installed in the inner tank, and the driving force of the motor (6) is applied to the center of the lower surface of the outer tank (2). Clutch 8 is attached to selectively rotate the inner tank (4) and the pulsator (5) by passing through, and the inner upper portion of the inner tank (4) is balanced by the load of the laundry during the rotation of the inner tankTo give support to a liquid balance member 9 is fixed.

In addition, a water supply pipe 11 having a water supply valve 10 is connected to an upper portion of the main body 1 so that water is introduced into the inner tank 4, and water used for washing is discharged to a lower portion of the outer tank 3. The drain hose 13 in which the drain valve 12 is installed is connected.

Therefore, when the cover 14 installed on the upper part of the main body 1 is opened, the detergent is put together with the laundry in the inner tank 4, the cover 14 is closed, and the washing start button is selected. Washing, rinsing, and dehydration are automatically performed within a certain time according to the control signal of).

That is, when the washing start button is selected, since the water supply valve 10 installed in the water supply pipe 11 is opened, when the washing water is supplied to the inner tank 4 through the water supply pipe 11 and filled by a predetermined height, the outer tank 2 The motor 6 fixed to one side of the lower surface of the drive is continuously repeated in the forward and reverse directions, and the driving force is transmitted to the clutch 8 attached to the center of the lower surface of the outer tub 3 through the belt 7. As the clutch operates by receiving the washing signal of the controller, the driving force of the motor 6 is transmitted to the pulsator 5 in a decelerated state. As the pulsator rotates, the laundry in the inner tank 4 is rotated and water flows together. The laundry is washed by the rotational force of the pulsator 5, the frictional force with the inner tank 4, the decomposition force of the detergent, and the like.

In this way, when the washing operation is completed, the drain valve 12 on the drain hose 13 connected to the lower surface of the outer tub 2 is opened, so the wash water is discharged to the outside through the drain hose 13.

In addition, when rinsing, the same operation as in the above-described washing operation is omitted, and hereinafter, it will be described later in more detail only when dehydration.

In dehydration, the clutch 8 receives the control signal of the controller in the state of draining the rinsing water used for the rinsing and in one direction sets the driving force of the motor 6 received through the belt 7 to the inner tank 4 and the pulsator. Since the inner tank (4) and the pulsator (5) rotates at the same time at a high speed at the same time, and thus the laundry in the inner tank (4) is pushed outward by centrifugal force, moisture contained in the laundry comes out. At this time, since the drain valve 12 installed in the drain hose 13 is opened by the control signal of the controller, the water drained from the laundry is drained to the outside through the drain hose 13, so that dehydration is completed. All work is done.

On the other hand, when the laundry is performed as described above, the laundry is pulled to one side by the centrifugal force according to the rotation of the inner tank 4, and the inner tank is to be flowed in proportion to the weight of the laundry. Since the liquid in the liquid balance member 9 is drawn in a direction opposite to the direction in which the laundry is pulled out, the amount of eccentricity of the laundry is canceled, so that the balance of the inner tank is maintained and accordingly, the flow of the inner tank 4 due to the washing of the laundry occurs badly. Do not.

However, such a pulsator type washing machine has excellent washing power, but since the water supply and drainage are made while the inner and outer tanks are always standing, there is a problem in that the water supply and drainage time become longer and the amount of water used increases. There is also a problem that the laundry is badly twisted or damaged because it rotates to the right, and in order to maintain the balance of the inner tank due to the washing of the laundry, the liquid balance member 9 must be fixed to the inner tank, thereby causing the washing machine to be heavy.

In addition, the drum type washing machine has an outer tub 22 fixed inside the main body 21, as shown in FIG. 2 of the accompanying drawings, in which the driving force of the motor 23 is transmitted through the belt 24 to rotate. An inner tank 25 is installed, and a water supply pipe 27 having a water supply valve 26 is connected to an upper portion of the outer tank 22, and a drain valve 28 is provided at one lower portion of the outer tank 22. The installed drain pipe 29 is connected, the weight portion 30 is fixed to the upper portion of the outer tank 22 to reduce the up and down vibration of the outer tank when dewatering.

Therefore, by opening the door 31 attached to the front of the main body 1, putting detergent into the inner tank 25 together with the laundry, closing the door 31 again and selecting the washing mode, the controller (not shown) Since the water supply valve 26 is opened in accordance with the control signal, the water to be used for washing enters the outer tank 22 through the water supply pipe 27 and is filled into the inner tank 25 rotatably installed in the outer tank and the outer tank 22.

In this way, when the water in the inner tank 25 is filled by a certain height, the motor 23 fixed to the outer tank 22 is repeatedly driven in the forward and reverse directions, and the driving force is transmitted to the inner tank 25 through the belt 24. Therefore, the laundry is washed by the friction force with the inner tank, the decomposing power of the detergent, etc. by repeatedly performing the process of the laundry rising to the top as the inner tank rotates and falls by its own weight.

When the washing operation is finished by the above operation, the drain valve 28 installed in the drain pipe 29 is driven by the control signal of the controller, so that water used for washing is discharged to the outside through the drain pipe 29, Subsequently, rinsing is performed by a similar procedure as in the above washing operation.

In addition, since the motor 23 is driven at a high speed after the rinsing stroke, the water contained in the laundry is discharged to the outside while the cloth sticks to the outside of the inner tank by centrifugal force and is discharged to the outside, whereby dehydration is performed. The upper and lower vibrations of the outer tub 22 according to the high speed rotation of the outer tub 22 are offset by the weight 30 fixed to the upper portion of the outer tub, and as a result, the upper and lower vibrations of the outer tub 22 are greatly reduced.

However, such a drum type washing machine has a water supply and drainage in a state where the inner tank and the outer tank are always laid down, so that the above-mentioned water supply and drainage time are shortened and water consumption is reduced, but the washing power is somewhat lower than that of a pulsator type washing machine. , Washing is not badly twisted or damaged because the drum rotates during washing, but there is also a problem that the washing time is long, and in order to reduce the upper and lower vibrations of the outer tank caused by the rotation of the drum, the weight must be fixed to the outer tank. There was also a problem that becomes heavy.

As described above, the pulsator type washing machine and the drum type washing machine have various problems, and the present applicant has been granted a registration by developing a complex washing machine to make the most of the advantages of the pulsating type washing machine and the drum type washing machine. The combined washing machine is a washing machine that allows the user to arbitrarily select a pulsator type and a drum type.

Then, when looking at the composite washing machine, as shown in Figure 3 of the accompanying drawings, the motor frame 102 and the outer frame 103 in the main body 101 is supported by a plurality of supports 104 in an integrated state The outer tub 105 is pivotally hinged to the outer tub frame 103, the door 106 is installed on the outer tub and the worm wheel 107 is fixed to the outer tub 103, and the war frame is fixed to the motor frame 102. The worm motor 109 is axially coupled to the rim wheel 107 to be engaged with the um wheel 107, the washing motor 110 is attached to the outer side of the lower surface of the outer tank 105, the outer tank 105 Inside the inner tank 112 is a pulsator 111 is integrated to be rotated under the driving force of the washing motor 110.

Therefore, the cover 113 installed on the upper portion of the main body 101 is opened, and then the door 106 of the outer tub 105 hingedly coupled to the outer frame 103 in the main body 101 is opened. ) Put detergent together with the laundry into the inner tank 112 and close the open cover 113 and the door 106.

In this state, when the user selects the pulsator washing button or the drum washing button, pulsator washing or drum washing is performed according to the selected mode.

That is, if the pulsator washing button is selected, the water to be used for washing into the outer tub 105 is supplied by a water supply means not shown in the state in which the outer tub 105 and the drum 112 are set up as shown in (a). The outer tank and the inner tank 112 are filled.

In this way, after the water is filled by a certain height, the washing motor 110 attached to the outside of the lower surface of the outer tub 105 is driven by receiving a control signal from the controller, so that the drum 112 and the drum installed in the outer tub 105 The integrated pulsator 111 is rotated together by the driving force of the washing motor 110 and accordingly the laundry is washed by the friction force with the drum, the decomposition force of the detergent.

Since the rinsing stroke and the dehydration stroke are similar to those of the pulsator type washing machine described above, they are omitted.

In addition, when the drum washing button is selected, the worm motor 109 attached to the motor frame 102 is driven by receiving the control signal of the controller, so that the worm 108 coupled to the worm motor rotates and the rotation force is the worm wheel 107. Since it is transmitted to the outer tub 105 through the inner tub 112, the inner tub 112 with the outer tub is rotated as shown in (b) around the hinge axis and used for washing with the outer tub 105 by a water supply means not shown. Water is supplied to the outer tank and the inner tank 112, and when the filling of the water is completed, the washing motor 110 is driven to rotate the inner tank 112, the laundry is washed.

In this way, when the washing stroke is completed, the water used for washing is drained and the rinsing stroke is completed continuously. When the rinsing stroke is completed, the worm motor 109 receives the control signal of the controller and reversely drives the outer tub 105 and the inner tank. The 112 is set up again as shown in (a), and at the same time, the washing tank 110 is driven at a high speed, so that the inner tank 112 rotates at a high speed, in which the process of dehydrating the laundry in the inner tank is a drum type washing machine described above. Similar to the action of

Comprehensive driving method for washing the combined washing machine as described above, the first step of the controller recognizes the pulsator type washing and drum type washing according to the user's mode selection; A second step of allowing the controller to recognize the pulsator type washing so as to allow the washing of the outer tank and the inner tank to allow the pulsator type washing, and to recognize the washing of the drum to lay the outer tank and the inner tank to allow drum washing; When the pulsator type washing is performed in the state where the outer tank and the inner tank are erected, the inner tank is rotated to perform washing, rinsing, and dehydrating strokes sequentially. A third step of sequentially performing only up to; In the drum-type washing, when the outer tub and inner tub are laid down, when the washing and rinsing stroke is completed, the fourth tubing may be sequentially made by setting up the outer tub and inner tub again and rotating the inner tub to complete the dehydration stroke.

However, in the conventional driving method of such a washing machine, regardless of the amount of laundry, the user performs pulsator type washing and drum type washing by choice. Therefore, when pulsating type washing is performed when washing a large amount of laundry, the laundry turns separately. Therefore, there is a problem that the washing power falls because there is no flow, and when the mode is selected as pulsator type washing, when the washing, rinsing, and dehydrating strokes are completed, the water tank and the inner tank are erected. In addition, there is also a problem that the feeding and draining time is also long, and when the drum washing is completed, the outer tank and the inner tank are completely erected and then the drum is rotated to start the dehydration stroke, so the laundry is sharply pushed to one side by centrifugal force. There was also a problem that severe vibration caused by dehydration.

The present invention has been made in order to solve the various problems described above, so that even if the user does not select the pulsator type washing and drum type washing, it is automatically input to the controller according to the amount of laundry, when washing the pulsator type washing and drum type washing Regardless of whether water is filled above a certain level, washing is performed with the outer and inner tanks laid down, and when the drum type washing, the drum is rotated while the outer and inner tanks are laid down when the rinsing stroke is completed and then the dehydration stroke is started. As it starts to stand, as the rotation of the inner tank becomes faster and faster, washing power is improved, as well as the amount of water supply, drainage time, and water consumption are reduced, as well as the vibration caused by high-speed dehydration.

According to an aspect of the present invention for achieving the above object, a first step of the controller recognizes the pulsator type washing and drum type washing according to the amount of laundry; A second step of erecting the outer tank and the inner tank when the pulsator type washing is recognized, and laying down the outer tank and the inner tank when the drum washing is recognized; A third step of completing washing, rinsing, and dehydrating strokes with the outer tank and the inner tank standing when the pulsator type washing is recognized, and completing only the washing and the rinsing stroke with the outer tank and the inner tank lying down when the drum washing is recognized; When the drum-type washing is completed from the recognized state to the rinsing stroke, the washing machine of the present invention was sequentially formed by rotating the inner tank of the lying state again and then rotating the high speed in the standing state to complete the dehydration stroke. A driving method is provided.

According to another aspect of the present invention for achieving the above object, a first step of the controller recognizes the pulsator type washing and drum type washing according to the amount of laundry; A second step of laying down the outer shell and the inner shell regardless of the recognition of pulsator type washing and drum type washing; A third step of completing the washing and rinsing strokes only when the washing and rinsing strokes are completed when the washing and rinsing cycles are completed when the drum washing is recognized; When the washing stroke is completed in the state in which the pulsator type washing is recognized, the outer tank and the inner tank are rebuilt to complete the rinsing and dehydration stroke. When the drum washing is completed, the washing tank is rotated while the inner tank in the lying state is rotated. There is provided a driving method of the present invention of the present invention in which a fourth step of sequentially completing the dehydration stroke by rotating at a high speed in a standing state is continued.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings of FIG. 5 and FIG.

5 is a flowchart illustrating a method of driving the present invention of a combined washing machine according to an embodiment, the present invention provides a method for controlling a washing machine, the method comprising: recognizing, by a controller, pulsator type washing and drum type washing according to the amount of laundry; Erecting the outer tub 105 and the inner tub 112 when the pulsator type washing was recognized, and laying down the outer tub 105 and the inner tub 112 when the drum washing was recognized; When the pulsator type washing is recognized, the outer tank 105 and the inner tank 112 are erected, and the washing, rinsing, and dehydration is completed. When the drum washing is recognized, the outer tank 105 and the inner tank 112 are laid down. Completing only washing and rinsing strokes; When the drum-type washing is recognized from the recognized state to the rinsing stroke, the inner tank of the lying state is turned while standing and then rotated at a high speed to sequentially complete the dehydration stroke.

Therefore, when the user puts the laundry into the inner tank 112, the weight sensor not shown detects the amount of laundry and sends the detected value to the controller, wherein the controller compares the preset value with the detected value to determine the detected value. If it is smaller than the setting value, it is recognized as the pulsator type washing mode. If the detected value is larger than the setting value, it is recognized as the drum type washing mode.

In this way, when the controller recognizes the pulsator type washing, the worm motor 109 does not operate. Therefore, the outer tank 105 and the inner tank 112 remain as they are. When the drum washing is recognized, the worm motor 109 controls the controller. Since the driver receives the signal, the outer tank 105 and the inner tank 112 installed inside the outer tank are rotated and laid down.

In the state where the outer tank 105 and the inner tank 112 are erected by the pulsator type washing recognition of the controller as described above, water is continuously supplied to the inner tank by the water supply means, and the water is drained by the drain means along with the load. , Rinsing, dehydration stroke is completed in stages, and in the state in which the outer tub 105 and the inner tub 112 are laid down by the drum-type washing recognition of the controller, water is continuously supplied to the drum by the water supply means and the drainage means Drainage is carried out by, and only the washing and rinsing strokes are primarily completed, and once the rinsing strokes are completed, the dehydrating stroke is entered.

On the other hand, when the dehydration stroke starts, the inner tank 112 receives a low-speed driving force of the washing motor 110 in a lying state, and rotates slowly. After a predetermined time, the driving force of the washing motor becomes faster and the worm motor 109 is also driven. Since the inner tank 112 lying down is rotated as shown in FIG. 7C with the outer tank 105 while the inner tank is erected, the laundry is stuck evenly to the circumferential surface of the inner tank by the centrifugal force caused by the rotation of the inner tank. Since the driving of the washing motor 109 becomes high speed from the time when the inner tank is erected, most of the moisture contained in the laundry is discharged by the centrifugal force due to the high speed rotation of the inner tank 112 to complete the dehydration operation.

In addition, Figure 7 is a flow chart showing another embodiment of the method of driving the present invention of the combined washing machine, another embodiment of the present invention comprises the steps of the controller recognizes pulsator type washing and drum type washing according to the amount of laundry; Laying down the outer tub 105 and the inner tub 112 irrespective of pulsator washing and drum washing; When the pulsator type washing is recognized, the outer tank 105 and the inner tank 112 are completed to the washing stroke in the lying state, and when the drum washing is recognized, the outer tank 105 and the inner tank 112 are washed and rinsed in the lying state. Completing only until administration; When the washing cycle is completed in the state in which the pulsator type washing is recognized, the outer tank 105 and the inner tank 112 are erected and rinsed, and when the drum type washing to complete the dehydration stroke is completed, the lying down is completed. The steps are completed in order to complete the dehydration operation by rotating the inner tank of the state again and then rotating it at a high speed in a standing state.

Hereinafter, a part overlapping with the above-described embodiment of the washing process by the driving method according to another embodiment of the present invention will be omitted as follows.

When the controller recognizes the pulsator type washing or the drum type washing according to the amount of the laundry put into the inner tank 112, the worm motor 109 is driven by receiving the control signal of the controller so that the inner tank 105 and the inner tank installed in the outer tank are installed. 112 is rotated and laid down irrespective of pulsator type washing and drum type washing.

In the state where the outer tank 105 and the inner tank 112 are laid down by the pulsator type washing recognition of the controller as described above, water is supplied by the water supply means into the inner tank, and only the washing administration is completed first, and the drum type of the controller In the state in which the outer tub 105 and the inner tub 112 are laid down by the washing recognition, water is supplied to the drum by the water supply means, and only the washing and the rinsing stroke are completed first.

On the other hand, in the state in which only the washing administration is completed by the above-described process, immediately after the outer tank 105 and the inner tank 112 are erected continuously, rinsing and dehydration is completed, and the washing is finished, and the washing and rinsing administration only 1 In the vehicle completed state, the washing operation is completed by completing the dehydration operation in the same manner as in the above-described embodiment.

Therefore, according to the present invention, the pulsator type washing machine and the drum type washing machine are automatically recognized and performed, and thus, the use of the washing machine is very convenient and the washing force is improved, and the drum type washing machine does not require a large amount of water to be used for washing. In addition to the savings, the water supply and drainage time is also greatly reduced.In the washing administration, you can also start washing by laying down the inner tank even in the pulsator type washing, so that the laundry is tangled and damaged, and the dehydration starts when the inner tank is built. Dehydration is completed with the inner tank erected, so when laundry is dehydrated, the laundry does not move to one side, so vibration does not occur significantly.
