It may be equal to or smaller than the dose. The capacity of the washing tank of each

washing unit

140 and 150 is not limited separately.

The first washing unit 140 and the second washing unit 150 may be a dry combined laundry treatment device that provides both a washing function and a drying function.

The above-described configuration of the first washing unit 140 and the second washing unit 150 are those that can be provided in a general laundry treatment machine, those who have a common skill in the art will be very obvious, Detailed description thereof will be omitted.

Referring to FIG. 2, both the first washing unit 140 and the second washing unit 150 are in the form of a front load washing machine, but both the first washing unit 140 and the second washing unit 150 may be in the form of a top load washing machine. In addition, the limitation of the form of the 1st washing part 140 and the 2nd washing part 150 is not limited. The second washing unit 150 may be disposed above the first washing unit 140 and may be disposed below the first washing unit 140.

When only the first washing unit 140 of the first washing unit 140 and the second washing unit 150 performs the washing, vibration may occur in the laundry treatment device 100 due to the rotation of the motor of the first washing unit 140. have.

The washing course of the first washing unit 140 and the second washing unit 150 may be composed of a washing stroke, a rinsing stroke, a dehydration stroke, a drying stroke, and the like. When the operation is being performed, the first washing unit 140 may be unbalanced due to the tendency of the laundry, and a large vibration may occur that may cause damage to the laundry treatment apparatus 100.

In the present invention, when a large vibration occurs in the laundry treatment apparatus 100 due to the rapid rotation of the motor 145, the first washing unit 140, the second washing unit 150 is supplied with water to reduce the vibration.

When vibration occurs due to the operation of the first washing unit 140, water is supplied to the second washing unit 150 disposed below the first washing unit 140 to the washing tank 202 of the second washing unit 150. When the liquid is filled, the center of gravity of the laundry treatment machine 100 is lowered to reduce the vibration.

In addition, since liquid such as water has a characteristic of absorbing seismic waves, the liquid filled in the washing tank 202 of the second washing unit 150 may reduce vibration generated from the first washing unit 140.

Hereinafter, each configuration for performing such an operation will be described in detail.

The first washing unit 140 operates the first water supply valve 149, the first input unit 144, the first display unit 142, the motor 145 for rotating the washing tub, and the overall operation of the first washing unit 140. The first washing unit 141 controls the 145, and the second washing unit 150 rotates the second water supply valve 159, the second input unit 154, the second display unit 152, and the washing tank. The second control unit 151 controls the overall operation of the motor 155 and the second washing unit 150 and the motor 155.

The vibration sensor 160 is disposed at a contact portion that is a portion where the first washing unit 140 and the second washing unit 150 are coupled to detect vibrations generated in the laundry processing apparatus 100.

The vibration sensor 160 transmits the detected vibration amount information to the second controller 151.

The second input unit 154 transmits the vibration sensing activation command to the second control unit 151 based on the user input. To this end, the second input unit 154 may be provided with a vibration sensing key separately. According to another embodiment of the present invention, the second control unit 151 may automatically perform the following operation without input of the vibration sensing activation command.

When the vibration sensing activation command is input through the second input unit 154, the second controller 151 activates an operation based on the amount of vibration sensed by the vibration sensing sensor 160. Accordingly, the second controller 151 controls the second washing unit 150 to supply water in response to the detected vibration amount received from the vibration sensor 160.

Specifically, when the amount of vibration detected by the vibration sensor 160 is greater than or equal to a set value, the second control unit 151 controls water supply to the second washing unit 150 so that a predetermined amount of water is supplied to the washing tank 202. To be filled. If the detected vibration amount is less than the set value, the second controller 151 detects the vibration through the vibration sensor 160 and waits.

The second control unit 151 controls the second water supply valve 159 disposed in the water supply pipe (not shown) to be opened so that water is supplied to the second washing unit 150. The second water supply valve 159 is disposed in the water supply pipe and is controlled by the second control unit 151. When the second water supply valve 159 is opened, water is supplied to the washing tank 202 of the second washing unit 150, and when the second water supply valve 159 is closed, the water supply is stopped.

When water is supplied to the second washing unit 150, the second control unit 151 may adjust the amount of water supplied to the second washing unit 150 in response to the amount of vibration detected by the vibration detecting sensor 160. Accordingly, as the amount of vibration detected by the vibration sensor 160 increases, the amount of water supplied to the second washing unit 150 may increase. This is because the greater the amount of vibration generated in the laundry treatment machine 100, the greater the amount of water needed to reduce the vibration.

The set value represents an amount of vibration enough to cause damage to the laundry treatment machine 100. That is, that the amount of vibration detected by the vibration detecting sensor 160 is greater than or equal to a set value indicates that vibration of the laundry processing device 100 is generated to a degree that is damaged, and the second control unit 151 may have a second amount. If the washing unit 150 is controlled to perform water supply, as the center of gravity of the laundry processing apparatus 100 is lowered and the water filled in the washing tank 202 absorbs vibration, vibration of the laundry processing apparatus 100 will be reduced. .

After supplying water to the second washing unit 150, the second control unit 151 controls the motor 155 of the second washing unit 150 to rotate at a preset speed. When the washing tank 202 of the second washing unit 150 filled with water rotates, a gyroscope effect is generated, and vibration of the laundry treatment apparatus 100 is reduced. To this end, the second control unit 151 may calculate the rotation speed of the second washing machine motor 155 generating the gyroscope effect based on the vibration amount detected in real time through the vibration detection sensor 160. .

According to another embodiment of the present invention, the second control unit 151 receives the vibration amount detected by the vibration sensor again after water supply is performed to the second washing unit 150, and if the transmitted vibration amount is equal to or greater than a set value, The motor 155 of the second washing unit 150 may be controlled to rotate at a preset speed. If the vibration of the laundry treatment apparatus 100 is not stabilized even though water is supplied to the second washing unit 150, the laundry treatment apparatus using the gyroscope effect caused by the rotation of the washing tank 202 filled with water It is to reduce the vibration of the (100). The second control unit 151 may wait until the washing of the first washing unit 140 is finished when the amount of vibration detected after the water supply is performed is less than the set value, and when the washing of the first washing unit 140 ends, The water in the second washing unit 150 may be drained.

According to another embodiment of the present invention, the second control unit 151 receives the vibration amount detected by the vibration sensor 160 again after the set time has elapsed after the water supply is performed to the second washing unit 150. The second control unit 151 controls the washing of the second washing unit 150 to be performed when the amount of vibration detected again by the vibration detecting sensor 160 is less than a set value. The tub washing is an operation of washing the washing tub 202 of the second washing unit 150. The second control unit 151 utilizes the water used for vibration reduction again in the tub washing.

According to another embodiment of the present invention, the second control unit 151, based on the amount of vibration transmitted from the vibration sensor 160, the first washing unit 140 is unbalanced laundry is concentrated in one place (UB, Unbalance) Can be determined.

If it is determined that the first washing unit 140 is in an unbalanced state (UB), the second control unit 151 controls water supply to the second washing unit 150.

The second control unit 151 receives the vibration amount detected by the vibration sensor 160 again after water supply is performed to the second washing unit 150, and the first washing unit 140 is based on the detected vibration amount. When it is determined that the state is unbalanced (UB, Unbalance), the motor 155 connected to the washing tub 202 of the second washing unit 150 is controlled to rotate at a preset speed. In addition, the second control unit 151 determines whether the first washing unit 140 is in an unbalanced state (UB), and controls the second washing unit 150 to perform water supply, and then the motor 155 is preset. It can also be controlled to rotate at speed.

Is formed. At least one vibration detection sensor 160 may be disposed on the four contacts. That is, four vibration detection sensors 160 corresponding to four contacts may be provided, or only one vibration detection sensor 160 may be provided at one contact. The number of the contact portion and the vibration detection sensor 160 is not particularly limited.

By combining the legs 13 and the

holes

9a, 9b, and 9c, the first washing unit 140 and the second washing unit 150 may be fixed and may not be separated during operation.

The vibration sensor 160 may be disposed at a contact portion of the first washing unit 140 and the second washing unit 150 to detect a stack state of the first washing unit 140 and the second washing unit 150.

The stack state of the first washing unit 140 and the second washing unit 150 refers to a state in which the first washing unit 140 and the second washing unit 150 are coupled to each other. On the contrary, when vibration occurs in the laundry treatment apparatus 100, the first washing unit 140 and the second washing unit 150 may be temporarily uncoupled, and this state may be referred to as a separated state. .

contacts

977 and 978 may be provided inside and / or to open and close a circuit (communication circuit or power circuit) by the slider 974.

The switch body 971 is provided with a body through hole 973 provided through the slider 974. The slider 974 is supported by the elastic support 976 provided in the switch body 971. Accordingly, when the first washing unit 140 is seated on the upper part of the second washing unit 150, the slider 974 moves toward the contacts 957 and 978, and the first washing unit 140 moves to the second washing unit 150. ), The slider 974 moves in a direction away from the contacts 997 and 978.

The contacts 997 and 978 are rotatably provided in the first contact 997 fixed inside the switch body 971 and the switch body 971, and are connected to the first contact 997 by the slider 974. It may include a second contact (978). When the first contact 997 and the second contact 978 are connected by the slider 974, the vibration detection sensor 160 detects that the first washing unit 140 and the second washing unit 150 are stacked, This is transmitted to the first control unit 141 or the second control unit 151.

The vibration sensor 160 may detect a stacking state and a separation state of the first washing unit 140 and the second washing unit 150 by detecting a stack state of the first washing unit 140 and the second washing unit 150. . In this case, when the first control unit 141 and the second control unit 151 starts washing, when the stack state of the first washing unit 140 and the second washing unit 150 is detected by the vibration sensor 160. Only, the first washing unit 140 or the second washing unit 150 may be controlled to perform the washing. This is because when the first washing unit 140 or the second washing unit 150 starts washing even if the first washing unit 140 and the second washing unit 150 are not stacked, the laundry treatment apparatus 100 may be rolled over or damaged. Because it can.

The vibration sensor 160 detects that the stacking state and the separation state of the first washing unit 140 and the second washing unit 150 are repeated during washing of the laundry processing apparatus 100, and thus, the laundry processing apparatus 100 is detected. The vibration generated can be detected. In this case, the vibration sensor 160 may detect the vibration amount of the laundry treatment apparatus 100 by measuring a speed at which the stacking state and the separation state of the first washing unit 140 and the second washing unit 150 are repeated. .

In another embodiment of the present invention, the vibration sensor 160 may include a means for detecting the pressure, the laundry treatment by sensing the pressure applied to the contact portion of the first washing unit 140 and the second washing unit 150 The vibration amount of the device 100 may be detected.

6 is a flowchart illustrating a control method of a laundry treatment machine according to an embodiment of the present invention.

In the control method of the laundry treatment machine according to the present invention, the second washing unit 150 does not perform the washing, the first washing unit 140 performs the washing.

If the vibration detection activation command is input through the second input unit 154 in a standby state in which the operation of the second washing unit 150 is stopped before the first washing unit 140 starts washing, the second control unit 151 Activates vibration detection (S10). Thereafter, the first control unit 141 controls the first washing unit 140 to perform washing according to the setting input through the first input unit 144 (S11).

The vibration sensing activation command may be input even after the first washing unit 140 starts washing. In addition, when the power of the second washing unit 150 is turned on, the second control unit 151 may activate vibration detection without a separate vibration detection activation command.

When the vibration detection is activated, the second control unit 151 controls the second washing unit 150 to perform a specific operation based on the amount of vibration transmitted from the vibration detection sensor 160. Thereafter, when the vibration is sensed through the vibration sensor 160 in the air, the second controller 151 determines the vibration amount and controls the operation of the second washing unit 150.

If the motor rotates rapidly, such as a drying stroke during the washing of the first washing unit 140, a large vibration may occur that may cause damage to the thin film processing apparatus 100, and the first washing unit 140 may be unbalanced. May be

The vibration sensor 160 is disposed at the contact portion of the first washing unit 140 and the second washing unit 150 to detect the stack state of the first washing unit 140 and the second washing unit 150 to wash the laundry machine 100. Detects the amount of vibration generated in (S12). According to another embodiment of the present invention, the vibration sensor 160 may detect the amount of vibration by sensing the pressure applied to the contact portion of the first washing unit 140 and the second washing unit 150. The vibration sensor 160 transmits the sensed vibration amount to the second control unit 151.

The second control unit 151 receives the vibration amount detected by the vibration detection sensor 160 and compares the detected vibration amount with a set value. If the detected vibration amount is greater than or equal to the set value (S13), the second control unit 151 controls to supply water to the second washing unit 150 (S14). The second control unit 151 may adjust the water supply amount according to the sensed vibration amount, and accordingly, the larger the water supply, the greater the water supply amount.

The second control unit 151 controls water so that the motor 155 of the second washing unit rotates at a preset speed after water is supplied to the second washing unit 150 (S15). As a result, a gyroscope effect is generated and vibration of the laundry treatment apparatus 100 is reduced.

If the laundry treatment device 100 is vibration generated more than the set value may cause damage to the laundry treatment device 100, the second control unit 151 supplies water to the second laundry unit 150 to the laundry treatment device ( Lower the center of gravity of the 100, absorbs the vibration through the water supplied, and by rotating the motor 155 of the second washing unit generates a gyroscope effect to reduce the vibration.

The vibration sensor 160 detects the vibration amount again after the set time elapses (S16). The vibration sensor 160 transmits the sensed vibration amount to the second control unit 151.

The second controller 151 receives the detected vibration amount again, and compares the received vibration amount with a set value. If the detected vibration amount is less than the set value (S17), the second control unit 151 controls the washing of the second washing unit 150 to be performed (S18). This is to once again utilize the water used to reduce the vibration to wash the second washing unit 150.

If the detected vibration amount is greater than or equal to the set value, the second control unit 151 continuously rotates the second washing unit motor 155 to reduce the vibration (S15).

According to another embodiment of the present invention, after the water supply is performed to the second washing unit 150 and the set time has elapsed, the vibration detecting sensor 160 detects the amount of vibration again and transmits it to the second control unit 151.

The second control unit 151 may determine that the motor 155 of the second washing unit has a preset speed when the amount of vibration detected again by the vibration sensor 160 after the water supply is performed to the second washing unit 150 is greater than or equal to a predetermined value. Control to rotate. If the detected vibration amount is less than the set value, the second control unit 151 does not control the second washing unit motor 155. When the vibration is sufficiently reduced only by the water supply, the second washing machine motor 155 is not operated to save power use.

According to another embodiment of the present invention, the second control unit 151 determines whether the first washing unit 140 is in an unbalanced state based on the amount of vibration detected by the vibration sensor 160. When it is determined that the first washing unit 140 is in an unbalanced state, the second control unit 151 supplies water to the second washing unit 150 and rotates the second washing unit motor 155 at a predetermined speed.
