[0002]

2. Description of the Related Art Recent fully automatic washing machines, by applying a rapidly developing sensor technology, display a standard amount of detergent corresponding to the amount of clothes by simply turning on the switch, and the washing water level, The mainstream method is to display the amount of washing water and automatically control the washing procedure. In order to reduce the cost of the washing machine itself, this type of washing machine displays the amount of detergent, the washing water level, and the washing water amount on one display device, and the display panel section shows the current situation of the washing machine. To inform the user.

[0003]

The fully automatic washing machine according to the prior art described above uses a single display device to display a standard amount of detergent,
The washing water level and the amount of washing water are displayed. For this reason, the user himself / herself grasps the process of the fully automatic washing machine in order to judge whether the displayed indication is the standard amount of detergent, the amount of water, or the water level, and the current sensor status. There is a problem that it is necessary to judge what is.

Further, as a method of avoiding the problems of the prior art, the display of the standard amount of the detergent and the display of the standard amount of the water level and the water amount are separately provided, and a display device for displaying them is provided. There is a method of providing the display panel of the automatic washing machine, but such a method causes a hardware cost increase for the display device and causes a problem that the value of the product becomes expensive.

An object of the present invention is to solve the above-mentioned problems of the prior art and to make it possible to clearly distinguish the indication of the detergent amount from the indication of the water amount and the water level using the same indicator. Another object of the present invention is to provide a fully automatic washing machine that can perform the above and can be configured at low cost.

[0006]

According to the present invention, the above object is to display the indication amount of the detergent on the display panel, the water level, and the water amount on the same display unit, in which case the first washing is performed. After sensing the detergent standard amount, the display of the required detergent amount is displayed by blinking the display part, then, after sensing the amount of cloth, the washing water level and the water amount are displayed by the continuous lighting of the display part, This is achieved by allowing the user to clearly display two types of states using one display unit.

[0007]

The present invention allows the display of the detergent amount, the water level, the water amount, the process of the fully automatic course from washing to rinsing to dehydration to be displayed on the display panel of the fully automatic washing machine. The display and the display of the water level and the water amount can be displayed on one display unit, and both can be displayed so that they can be clearly distinguished by blinking and continuous lighting of the display unit.

Conventionally, the display of the detergent standard amount and the display of the water level and the water amount are performed in the same display mode on one display unit. If you use separate indicators to display the detergent amount and the water level and water amount at the time of washing so that you can judge the situation easily, it is limited. In addition, it is necessary to provide the display section for displaying the process of the fully automatic course, the detergent indication, the water amount, and the water level on the display panel surface, which complicates the display panel and increases the cost.

According to the present invention, the detergent standard display and the water level and water amount display can be displayed on one display unit, and both can be displayed so that they can be clearly distinguished by blinking and continuous lighting of the display unit. So, the standard amount of detergent and the water level at the time of washing,

A fully automatic washing machine according to an embodiment of the present invention is
As shown in FIG. 1, the outer tub 2 is supported by four suspension rods 5 attached to corner plates 21 arranged at the four corners of the outer frame 1 and arranged inside the outer frame 1. It is configured. The hanging rod 5 is provided with a push spring 4 that absorbs vibrations during washing and dehydration, and the outer tub 2 is connected via the spring 4.
Is supported.

Inside the outer tub 2, a balancer 6 is provided at the upper part thereof, and a washing tub 3 having a stirring blade 7 at the bottom is installed. Further, the stirring blade 7 is connected to the motor 20 via a clutch 14, a clutch pulley 15, a V belt 16 and a pulley 17 which are provided on the lower outside of the outer tub 2.

In the fully automatic washing machine having the above-described structure, when washing is performed, the lid 18 is opened, the clothes to be washed are put into the washing tub 3, and the water supply hose 11 is instructed by the control section 19. After supplying water to the washing layer 3 via the water supply valve 10, the motor 20 is rotated in the forward and reverse directions. The rotation of the motor 20 is transmitted from the motor pulley 17 to the clutch pulley 15 in the clutch 14 through the V-belt 16, and the stirring blade 7 located at the center of the washing tub 3 is operated by the operation of the clutch 14. Rotate.

During drainage, the motor 20 is stopped and the drainage valve 12 is opened in response to a command from the control unit 19. As a result,
The wash water or rinse water in the washing tub 3 is discharged out of the machine through the drain valve 12 and the drain hose 13. After that, the dehydration process automatically proceeds, but during dehydration, the laundry layer 3 may eccentrically rotate depending on the state of the clothes in the laundry layer 3,
As a result, the outer tub 2 vibrates greatly, and in order to prevent the eccentric rotation of the washing layer 3 and the vibration of the outer tub 2, a balancer 6 is provided above the washing tub 3 to prevent vibration of the outer tub 2 due to dehydration. To prevent.

For dehydration, the rotation of the motor 20 is transmitted to the clutch 14 via the V-belt 16 as in the case of washing, the washing tub 3 is rotated at high speed by the control of the clutch 14, and centrifugal force is applied to the inside of the clothes. The water is drained from the dehydration hole 3a provided in the washing tub 3 to the outer tub 2.
The drained washing water is discharged to the outside of the machine via the drain valve 12 and the drain hose 13.

As shown in FIG. 2, the control unit 19 described with reference to FIG. 1 is composed of a microcomputer 34 and various input / output devices. In this control unit 19, the microcomputer 34
I / O by the timer 33, the CPU (central processing unit) 32, the memory 31, the input port 29, and the output port 30
It is composed of an O port. The processing of the microcomputer 34 is executed by the CPU 32 using the timer 33 and the memory 31 connected via the data bus.
As for the control command at the time of washing, the CPU uses the arithmetic unit and the control unit provided therein to fetch and decode instructions, perform arithmetic and logical operations, read and write control of the contents of the designated address of the memory, It is generated by executing the input / output control to the specified address to the input / output device according to the flow of the program.

The memory 31 stores programs and data, and is composed of two types, a RAM having both read and write functions and a ROM having only read functions. RAM stores data,
It is used as a work area when executing programs,
The ROM stores predetermined programs, fixed data, etc., and is used when the same processing is executed.

The input port 29 and the output port 30 are C
It is an interface for exchanging data between the PU 32 and an input device and an output device, and is generally called an I / O port.

The input port 29 receives status signals indicating various states of the fully automatic washing machine, and these signals are sent to the CPU 3
Give to 2. These input state signals are mainly signals from the power switch 23, the water level sensor 22, the lid switch 24, the program selection switch 25, the start / stop switch 26, the detergent standard amount, the cloth amount sensor 35, and the like. Further, the output port 30 receives commands from the CPU 32 to various output devices, and sends these commands to the motor 2
0, water supply valve 10, drain valve 12, clutch solenoid 2
7. The alarm 28 is given to the progress indicator 36 and the like of the display panel section to drive these output devices.

As a result, the CPU 32 can control the washing machine based on the state of the fully automatic washing machine and cause the washing machine to perform a series of washing operations. As a result, the operation of the washing machine is controlled in the same manner as the mechanical control including the cam switch.

Next, control of the fully automatic washing machine by the microcomputer control described above will be described with reference to FIG. 3 showing a specific washing process.

When the worker presses the power switch 23, selects the standard laundry course by the program selection switch 25, and presses the start / stop switch 26, the washing machine causes the water supply hose to be instructed by the CPU 32. Water is supplied from 11 to the washing tub 3 through the water supply valve 10. When the CPU 32 determines, based on the information from the water level sensor 22, that the washing water has entered the washing tub 3 by a prescribed amount, it starts the prescribed washing operation. After the washing operation is completed for the specified time, the washing water is discharged to the outside of the machine through the drain valve 12 and the drain hose 13. Then, dehydration is performed, and the water in the clothes is drained by the centrifugal force from the dehydration hole 3a for dehydration, and then water for rinsing is performed to perform rinsing.

The fully automatic washing machine to which the present invention is applied performs a series of washing operations as described above under the control of a microcomputer.
This is to wash clothes, etc., and at that time, the user senses the amount of clothes, etc. that has been put in for washing in advance, and determines and displays the approximate amount of detergent according to this. Prompt the introduction of detergent to determine the amount of wash water and supply the required wash water.

Next, a cloth amount sensing method for measuring the amount of cloth such as clothes to be washed for determining the standard amount of detergent will be described with reference to FIGS.

FIG. 4 is a diagram showing a configuration of a circuit for detecting a back electromotive force of a phase advancing capacitor of a motor for explaining a cloth amount sensing method according to an embodiment of the present invention, and FIG. 5 is a waveform diagram for explaining its operation. FIG. 6 is a diagram illustrating the relationship between the time width of the sensing pulse and the cloth amount. In FIG. 4, 39 is a phase advancing capacitor, 36a and 36b are triacs, 37 is a photocoupler, and 38 is an inverter.

In the circuit shown in FIG. 4, the motor 20 is driven for washing, rinsing, etc., and the stirring blade 7 is rotated forward and stopped.
When performing the control for reversing, the microcomputer 34 alternately sends a control signal to the gates of the triacs 36a and 36b so that the triacs 36a and 36b are alternately turned on. As a result, the motor 20 is controlled so that its rotation direction is forward, stopped, or reversed.

For sensing the amount of cloth, the laundry clothes or the like to be washed are put into the washing tub 3, the power switch 23 is pressed,
By pressing the start / stop switch 26, the operation of the motor 20 as described above is performed for a short time, and the stirring blade 7 located in the central portion of the washing tub 3 is normally and reversely rotated to wash the laundry clothes. Is performed to detect the back electromotive force of the capacitor 39 immediately after the drive power to the motor 20 is stopped. That is, in the sensing of the cloth amount, the resistance applied to the stirring blade 7 changes depending on whether the laundry clothes are large or small, and the counter electromotive force of the capacitor 39 due to inertial rotation immediately after the driving power of the motor 20 is stopped. Since the cycle of is changed, it is performed by detecting the degree of this change.

In FIG. 5 showing the waveforms of the respective parts for explaining the sensing operation as described above, the microcomputer 34 sends the ON command 39a and subsequently the OFF command 39b to the triac 36.
Suppose it is given to a. The motor 20 is a triac 36a.
Is driven by the applied AC power while it is on, and rotates, and when the triac 36a is turned off, the triac 36a stops while reducing the rotation speed. The amount of decrease in this rotation speed is
Varies depending on the amount of load for zero.

As a result, the counter electromotive force of the phase advancing capacitor 39 is the waveform 4 when the motor 20 is driven and is rotating.
The waveform changes from 0 to a waveform 40a after the triac 36a is turned off. Waveform 4 after turning off this triac 36a
In 0a, the cycle is gradually lengthened and the peak value is gradually reduced.

The counter electromotive force of the capacitor 39 is shaped into a rectangular wave 41 as shown in FIG. 5 via the photocoupler 37 and the inverter 39, and is taken into the microcomputer 34. The rectangular wave 41 is taken into the microcomputer 34 by the function of the cloth amount (detergent reference amount) sensor 35 shown in FIG.
A rectangular wave 41 immediately after the triac 36a is turned off is input to the microcomputer 34.

The amount of cloth can be sensed by the resistance of the cloth applied to the stirring blade 7, and by detecting the reduction rate of the rotation speed of the motor 20 after the triac 36a is turned off. That is, the microcomputer 34
Is measured by changing the time Δt of one cycle immediately after the triac 36a of the rectangular wave (sensing pulse) 41 shown in FIG.

The experimental result of this variation is shown in FIG. 6, and it can be seen that the Δt of the sensing pulse 41 becomes longer in proportion to the load amount, that is, the cloth amount. Utilizing such a relationship, when the sensing pulse 45 is taken into the microcomputer 34, the microcomputer 34 measures the pulse width Δtmsec of the sensing pulse 41 and corresponds to the length of Δtmsec. It is possible to make the determination of a large amount and a small amount.

The microcomputer 34 determines the standard amount of detergent according to the determination of the amount of cloth obtained by the above-mentioned method,
In addition, the washing water level is selected and determined to be any one of low, medium, and high. Then, for sensing the cloth amount for determining the standard amount of detergent, only the cloth such as clothes to be selected is put into the washing tub, and the pulse width of the sensing pulse is detected by the above method without water injection. Further, the sensing of the amount of cloth for determining the washing water level may be the same as the method for determining the standard amount of detergent, but usually the cloth such as clothing to be selected is selected. It is carried out by pouring into a washing tub and supplying a predetermined amount of water, and detecting the pulse width of the sensing pulse by the method described above.

As described above, the cloth amount obtained by the cloth amount sensing for determining the standard amount of the detergent and for determining the washing water level and the water amount is used.
Has data indicating the relationship between the sensed amount of cloth and the standard amount of detergent, and data indicating the relationship between the sensed amount of cloth, the washing water level, and the amount of water, and based on these data. It is possible to determine the standard amount of detergent, the washing water level, and the amount of water.

If the standard amount of detergent is determined as described above, the microcomputer 34 displays the amount and prompts the user to add detergent, and if the washing water level is determined, the washing is performed via the water supply valve 10. Water is supplied into the tank 3. The water is supplied while monitoring the water level by the water level sensor 22 until the water level corresponds to the amount of cloth determined above.

That is, as shown in FIG. 2, the microcomputer 34 continuously monitors whether or not the water level determined based on the cloth amount is reached by the water level sensor 22 while supplying water from the water supply valve 10. When the signal from the water level sensor 22 becomes the same as the condition determined by the microcomputer 34, the water supply valve 10 is stopped, the process proceeds to the washing step, and washing is started.

As described above, in one embodiment of the present invention, the standard amount of detergent and the amount of washing water can be basically determined by the same method. In this way, determining the standard amount of detergent is necessary to remove dirt because the amount of cloth (load) of clothes increases and the amount of dirt attached to clothes increases in proportion to it. This is because it is also necessary to increase the amount of detergent. Then, the determined standard amount of detergent and the determined washing water level are displayed on the display panel section.

Next, a method of displaying the standard amount of the detergent and displaying the water level and the water amount according to an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to 0.

FIG. 7 and FIG. 8 are views for explaining a method for displaying the detergent standard amount and the water level and the water amount when the display on the display panel is performed by the LED. In FIGS. 7 and 8, 42
Is a display panel section, 43 is a fully automatic course selection menu key, 44 is a manual selection menu key, 45 is a manual water amount selection key, and 46a to 46g are display LEDs.

As shown in FIGS. 7 and 8, the display panel section 42 for displaying the control process of the fully automatic washing machine is provided with a start / stop 26 key, a fully automatic course selection menu key 43, a manual washing and rinsing operation. A manual washing menu key 44 for selecting dehydration and a manual water amount selection key 45 are arranged.

When, for example, the manual water washing machine key 45 of the display panel section 42 is pressed, the L for displaying the water amount is displayed.
When the ED 46a is high, medium, and low, the water level portion displayed on the panel portion 42 is sequentially lit, and when the manual washing menu key 44 is pressed, the washing LED 46b, the rinsing LED 46c, and the dehydration LED 46d are sequentially lit. However, with these, arbitrary washing conditions can be set.

Also, a fully automatic course selection menu key 43
When is pressed, the LED 46e of the fully automatic standard course
By pressing this fully automatic course key several times, the strong course LED 46f and the soft course LED 46g are sequentially turned on to notify the menu situation of the fully automatic course.

In a fully automatic washing machine, generally, when the start / stop key 26 is pressed, the LED 4 of the fully automatic standard course is displayed.
6e lights up, and the standard amount of detergent is automatically displayed by the above-described method for sensing the standard amount of detergent. However, in order to avoid the complexity of the display panel unit 42 and to reduce the cost of the display panel unit 42, the display panel unit 42 usually has a detergent standard amount, a water amount, and a washing water level described by printing, etc. The LED 46a that lights up in the order of medium, high and high is used both for displaying the detergent standard amount and for displaying the water level and the water amount. For this reason, it is difficult for the user to clearly determine whether the LED 46a is lit and moved as high, medium, and low to indicate the water amount, the detergent amount, or the water level.

In one embodiment of the present invention, the LE for display described above is used.
Depending on whether the lighting method of D46a is continuously lit or blinked, the display of the water level and water amount and the display of the detergent standard amount,
This allows the user to easily distinguish.

That is, in one embodiment of the present invention, when the start / stop key 26 is pressed and the standard amount of detergent is sensed and then the detergent usage amount is displayed, the aforementioned display LED 46a is shown in FIG. As described above, the proper amount of detergent is displayed as a blinking state. The user can determine that the standard amount of detergent is displayed because the LED 46a is blinking.

Next, the fully automatic washing machine according to the embodiment of the present invention supplies a fixed amount of water from the water supply valve 10 into the washing tub 3 and senses the amount of laundry by the above-mentioned amount of laundry sensing. When the water level and the water amount are determined and the wash water amount reaches a prescribed water level (water amount) matching the laundry amount, the LED 46
A is changed from a blinking state to a continuous lighting state as shown in FIG. The user can determine that the water level and water volume of the laundry are displayed by the LED 46a being in the continuous lighting state.

In the above description, the indication of the detergent standard amount is displayed as a blinking display and the display of the water level and the water amount is shown as a continuous lighting display. However, even if the display state is reversed, the same discrimination as described above can be performed. .

As described above, one embodiment of the present invention is the LED for displaying the detergent standard amount and the LED for displaying the water level and the water amount.
Even if and are not separately installed on the display panel unit 42, they can be displayed separately by the shared LED, and the cost can be reduced.

FIG. 9 and FIG. 10 are views for explaining a method for displaying the detergent standard amount and the water level and the water amount when the display of the display panel is performed by the fluorescent display, the liquid crystal display or the like. In FIGS. 9 and 10, reference numerals 44a to 44c denote menu keys for washing, rinsing, and dehydrating the manual selection menu, and other reference numerals are the same as those in FIGS. 7 and 8.

The display section 42 shown in FIGS. 9 and 10 is an LED.
Instead of the display by the fluorescent display, liquid crystal display, etc., the water level, the water amount display, and the detergent reference amount display are displayed in characters, respectively.Press the start / stop key 26 to display the above detergent reference amount. After sensing the cloth amount for determination, the display unit 46a that also displays the water amount and water level.
Displaying the standard amount of detergent is the same as in FIGS. 7 and 8.

Also in this example, in the case of the display of the standard amount of detergent according to the embodiment of the present invention, in order to clearly indicate this, the detergent amount measuring cup-shaped display portion 46a of the display panel 42 is displayed. Is displayed as a blinking state as shown in FIG. Further, when the water level and the water amount are determined and displayed, the continuous lighting state is displayed as shown in FIG.

According to the embodiment of the present invention, it is possible to clearly inform the user whether the detergent amount is displayed, the water level, or the water amount is displayed. Also in this case, the same effect can be obtained even if the method of blinking the display and the continuous lighting is reversed between the display of the detergent standard amount and the case of the water level and the water amount.

FIG. 11 is a flow chart for explaining an example of the overall operation of one embodiment of the present invention. Hereinafter, a standard washing operation of the fully automatic washing machine according to the exemplary embodiment of the present invention will be described with reference to the illustrated flow.

According to the above-described operation example, the same display can be used to allow the user to clearly determine whether the detergent amount is displayed, the water level, or the water amount is displayed.

FIG. 12 is a flow chart for explaining another example of the overall operation of the embodiment of the present invention. Hereinafter, a washing operation of the fully automatic washing machine according to the exemplary embodiment of the present invention for saving detergent (saving detergent) will be described with reference to the illustrated flow.

This operation example is an operation example in the case of performing laundry in which detergent is saved, and the reference amount of detergent is also determined by sensing the amount of laundry for determining the washing water level. That is, when the load amount corresponding to the amount of laundry clothes is set to the washing water level "high", one of the LEDs 46a for displaying the detergent, the amount of water, and the water level on the display panel 42 is controlled to a blinking state. However, when the washing water level "low" or "medium" is set as the load amount suitable for the laundry clothes amount, one of the LEDs 46a for displaying the detergent, water amount, and water level on the display panel section 42 indicating "low" blinks. It controls the state.

Since the blinking state of the LED 46a means the standard amount of detergent as described above, the user must
If "medium" of 46a is blinking, the detergent amount is added according to the standard amount of the detergent by the measuring cup. However, the amount of washing water and the water level required for washing are the “high” water levels obtained by the cloth amount sensing.
Water is supplied until the specified "high" water level is reached, during which L
The ED 46a indicating "medium" keeps blinking. And
When the prescribed "high" water level is detected by the water level sensor 22, the LED 46a displays the washing water level and the water amount,
The "medium" blinking state is switched to the "high" lighting state.

Another operation example of the above-described embodiment of the present invention will be described in more detail with reference to the flow chart shown in FIG.

(1) When the start / stop switch 26 is pressed, the microcomputer 34 controls the water supply valve 10 via the I / O port to supply water into the washing tub 3.
The amount of water supplied at this time is only the amount necessary to sense the water level of the washing water based on the information from the water level sensor 22 and the amount of clothes for determining the water amount, and has reached the prescribed water level and water amount. When stop the water supply. At this time, the LED 46a of the display panel 42 is in a state where blinking, continuous lighting, or the like is not yet displayed (steps 121 to 12).

The water supply is continued up to the prescribed water level satisfying any one of "low", "medium" and "high" (steps 12A and 12B).

(7) When the water level reaches the specified level, the LED 46a indicating the water level which is the true value obtained by the cloth amount sensing 60.
Is lit continuously for display (step 12C).

(8) After that, the washing operation is performed for a prescribed time, and the next process such as drainage, dehydration and rinsing is further executed (steps 12D and 12E).

According to the above-described operation example, the same display can be used to allow the user to clearly determine whether the detergent amount is displayed, the water level, or the water amount is displayed. In addition, according to this operation example, it is possible to determine the reference amount of the detergent, the water level, and the water amount by sensing the amount of cloth once, and further, as the reference amount of the detergent, regardless of the water level and the water amount, Since only "medium" and "low" are instructed, detergent-saving laundry can be performed.

As described above, according to the embodiment of the present invention, the same display is used for the indication of the detergent standard amount and the indication of the water level and the water amount, and these indicators are blinked and continuously lit. It is possible to separately display, and thereby, it is not necessary to separately arrange the indicator for the standard amount of the detergent and the indicator for the washing water level and the water amount on the display panel 42, and the complexity of the display panel can be eliminated. In addition, the cost of the display panel can be reduced.

[0077]

As described above, according to the present invention, 1
The display of the detergent level and the water level (water level) can be clearly displayed by blinking or continuous lighting on one display, so it is possible to display these on separate displays. By comparison, the cost for display can be reduced.

Further, according to the present invention, when washing clothes which are lightly soiled, the amount of detergent is decreased and the water level (water amount) is increased. It can be specified separately and the detergent can be saved.
