Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for operating a fully automatic washing machine, and is particularly applicable to a case where water is supplied to a specified amount of water into a washing tub and the time required to supply the water is longer than the specified time. , relates to an operating method in which the rinsing method is switched from a normal method to a special method.

The operation instructions in current fully automatic washing machines are based on programs set by a group of cam switches, but the programs are therefore fixed, making it difficult to complicate the applied operations and control.

On the other hand, if you program the timer device using a computer such as a microcomputer and make the timer device electronic,
This makes it possible to exchange information with the washing machine itself, making it easier to use and allowing you to create programs with optimal conditions for smooth operation.

Generally speaking, first of all, regarding the water supply mode, the water supply time of the water supply process in the above-mentioned fully automatic washing machine differs depending on the set water level, but it depends on the water pressure of the water supply source. It depends greatly.

For example, in areas with low water pressure, water supply is slow and takes a long time.

On the other hand, a normal washing program includes rinsing while pouring water, and rinsing without pouring water until it reaches the specified water level.
There are three types: tamesu suki, rinsing by sprinkling water in a shower during dehydration without storing water to a specified water level, and dehydration rinsing.

Of the above, water injection rinsing and dehydration rinsing are both methods whose rinsing efficiency is affected by the amount of water supplied, but both have unique effects, so they are used in appropriate places in the rinsing process.

In other words, when dehydrating and rinsing is performed when the detergent concentration is high, a large rinsing effect can be achieved with a small amount of water.

Additionally, water rinsing is effective in removing debris and foam floating on the water surface, and is used as the final pampas rinse.

If the rinsing efficiency is affected by the amount of water supplied above,
There are high hopes for the development of a control operation method that corrects this.

However, as mentioned above, in the current situation where the time limit is determined by a mechanical cam switch, the time limit for water supply rinsing etc. must be uniformly determined regardless of the amount of water supply time. It has the disadvantage that it uses more water than necessary in areas, and it has the disadvantage that sufficient susuki performance cannot be obtained in areas with low water pressure.

As mentioned above, conventional washing machines did not have a function to judge the supply capacity of the water supply source and use that information during rinsing, so we adopted a time cycle that provides satisfactory rinsing performance in general standard water pressure areas. Was.

Based on the above, there has been a desire for a control method that can stably supply a certain proportion of the specified amount of water and an applied invention derived from the control method.

The present invention eliminates the drawbacks under the above circumstances and meets the demands, and in order to perform optimal rinsing, the water supply time in the water supply process of a fully automatic washing machine is calculated using a computer. It is temporarily stored inside the , and on the way,
The main purpose of this project is to provide a method for operating a fully automatic washing machine that performs optimal rinsing using these memorized values, and the main purpose is to enrich specific rinsing-related programs related to the optimal control method. be.

The feature of the present invention is that a fully automatic washing machine has an instruction control unit that causes each washing process to be performed according to the set order, supplies water to the washing tub up to a specified amount of water, and causes a predetermined rinsing process to be performed. In the operating method of the fully automatic washing machine, if the above-mentioned water supply time period takes a relatively long time, the operating method of the fully automatic washing machine is such that it automatically executes special corrections that are set in advance from the normal rinse program. be.

Next, an embodiment of the operating method according to the present invention will be described, but in order to make it easier to understand, it will be explained that it solves the other drawbacks of the conventional method mentioned above and also meets the requirements. The overall configuration including the configuration, that is, the method of operating a fully automatic washing machine consisting of a series of configurations, in short, the parts shown in the drawings through the method incorporating the means according to the present invention. This will be explained in detail.

First, what is shown in FIG. 1 is, for example, a calculator such as a microcomputer in a fully automatic washing machine incorporating the present invention, that is, a computer having a calculation function and instructions to perform each washing process in a set order. The internal functions of the control unit PS,
This is an abbreviation including the relationship with input/output terminals, and a double arrow indicates a data bus or an address bus.

Note that such an instruction control unit PS is incorporated, for example, in the frame of a washing machine, and is adapted to display the washing process in correlation with the washing program flow (see Fig. 5), which will be described later. A progress indicator (see FIG. 3) along the line is also attached, for example, to the surface of the frame.

Each block inside the instruction control section PS will be explained next.

First, the input/output terminals of A-I (C and D are input/output terminals.

) is the ALU section (Arithmetic Logic
It is organically combined with the TJnit (arithmetic logic unit) to store calculation results and processing data in the ACC section (accumulator), and the ALU section, which has functions such as calculation and judgment, is the central part of the instruction control section PS. It constitutes.

In addition, C1 in the above ACC section is the carrier IJ-F/F.
, C2 is a carry evacuation F/F.

Here, F/F is a flip flop.

C1 of the carry IJ-F/F indicates the presence or absence of carry (carry) and borrow (borrowing) during addition and subtraction.
In F, in addition, C double has a carry, C-0 has no carry, and in subtraction, C=1 has a borrow.

C-O indicates no borrowing.

In addition, C2 of the carry save F/F is used for interrupt processing (INT
), the contents of Kiya'J-F/F are temporarily saved.
It is F.

The ROM section (read-only memory) is a storage section into which procedures for operating the washing machine, setting conditions for judgment, rules for processing various information, etc. are loaded in advance.

The counter for addressing the program stored in this ROM section is performed by the PC section (program counter) described below the iRoM section.

5TACK section (stack register) is a subroutine
It is used to save the contents of the PC section when there is a call or when there is a request for interrupt processing.

RAII (random access memory) is used to store data, and DP (data pointer) is a counter that addresses data in this RAM section.

The TIMER section (timer) can set a time limit by a timer set command, and by accumulating these time limits, each process stored in the ROM section is carried out on time. 3. Interrupt control circuit When the interrupt processing request signal INT is input to the interrupt processing section, the instruction in progress can be interrupted and fetched.

The CLOCK GENERATOR section (clock generator) has terminals CLo and CL1, which will be described later, and controls the timing of the operation of the instruction control section PS.

Next, FIG. 2 shows the external appearance of the above-mentioned instruction control section PS, together with the order in which its terminals are arranged.

In the figure, terminal NO, 21 (hereinafter referred to as VSSX, terminal 21).

The same goes for the others. ) and terminal 41 (VGG) are the instruction control unit P.
This relates to the power supply that drives S.

The terminal groups A, B, C, and D described above are each made up of four signal terminal groups, and are responsible for the input of the instruction control section PS, and also the terminal group E.

F, G, H, and ■ are each made up of a group of four signal terminals (only T and ■ are three), and control the output of the instruction control section PS.

In addition, terminal 1 (CLl), terminal 42 (CLO)
is a CLOC that controls the timing of the operation of the instruction control unit PS.
The external terminal for the LC resonant circuit for the K GENERATOR section is the terminal, terminal 6 (INT) is the interrupt processing request input terminal, terminal 7 (RES) is the reset input terminal, and terminal 2
0 (TEST) is a test terminal of the instruction control unit PS.

FIG. 3 shows the display output circuit of the instruction control unit PS and its peripheral circuits, where Q is a two-digit numeric display tube, and R is a 12 progress display from Ll to L12. This is a progress display section consisting of lamps, etc.

That is, Acos mentioned earlier,) Deba 1. As an example, a total of 1 terminal group for output terminals E, G, H and
Five tubes are used as displays, and the two-digit numerical display tube Q displays the remaining time of the entire process, which uses fluorescent lights or light emitting diodes to notify the progress status. Progress display is performed using the 12 progress display lamps L1 to L12 as described above, but generally, long-life light emitting diodes are used.

However, there is no problem in using a liquid crystal or the like as other display tubes.

The outputs from the group of 15 terminals are processed by a decoder, and a driver (amplification circuit) supplies a current of 10 to 20 mA per element.

Further, FIG. 4 shows an example of the display on the numeric display tube Q.

That is, when the remaining time is 15 minutes to 14 minutes, 15 is displayed as shown in A of the figure, and when the remaining time is 1 minute to 0 minutes, 0 is displayed as shown in the figure.

Also, if the water is not filled within a certain set time during the water supply process, an error display will be displayed consisting of a horizontal bar at the top and the letter E, as shown in Figure C, to indicate an inlet error. is displayed.

Next, FIG. 5 shows the layout of the panel portion such as the surface of the frame body.

In the figure, 10 is a panel decoration board, 20 is a power switch,
30 is a fully automatic cycle switching section, 40 is a program switching section, 50 is a time changing section, 60 is a start button,
70 is a pause button, 80 is a water level switching unit, 90 is a
In the buzzer volume switching section, 100 is a water supply port.

Then, S1 to S6 in the fully automatic cycle switching section 30
The display corresponds to the display of severe dirt, normal dirt, light dirt, sweater, dress shirt, and diaper corresponding to 81 to S6 in the table described below, and the display of ■ to V in the program switching unit 40 corresponds to , which similarly correspond to the display of washing only, Susuki→dehydration, washing→rinsing, draining/dehydration, and softener agitation, which correspond to Steps to V in FIG.

That is, the panel decoration plate 10 covers the entire panel section and is made of a metal plate such as aluminum with a pattern printed on it, and the power switch 20 controls the on/off of the main circuit. .

Further, the steps of the fully automatic cycle switching section 30 corresponding to the display strip shown to the right of the switch are stored in the ROM section of the instruction control section PS.

Further, the program switching section 40 is set so that washing, rinsing, and dehydration processes can be selected in combination, and the time changing section 50 is configured to independently select each washing, rinsing, and dehydration process. This is related to a switch for manual settings that can be changed based on an idea.

As mentioned earlier, the progress display section R consists of 12 progress display lamps, as shown in the figure, 5 for the washing process, 4 for the Susuki process, and 3 for the drainage process. This is what is used.

Each of the progress display lamps in the progress display section R flashes and lights up in a manner corresponding to the display band written below.

That is, the lights are turned on according to a process determined by a combination of six types of fully automatic cycle switching section 30 and five types of program switching section 40.

That is, for example, when the top input button of the fully automatic cycle switching section 30 is pressed, a human input signal (not shown) is connected to the input terminal group A-D of the instruction control section PS.

) is transmitted to the instruction control unit PS, this input is judged by the ALU unit, and the address in the ROM unit is indicated to indicate how to process it, so a command to call the address is issued to the PC unit, and the ROM is The contents of the corresponding address from the ALU
The ACC section outputs instructions for appropriate actions.

Since the above-mentioned top entry capotan is the longest program, all 12 progress display lamps in the progress display section H are lit.

Since the numeric display tube Q is not in operation at this time, it displays the letter P to indicate that it is in a pause (temporary stop).

The pause mode cannot be canceled unless the start button 60 is pressed manually, and the pause button 70, contrary to the start button 60, continues to operate unless it is pressed manually.

Further, the water level switching unit 80 is a human-powered switch that sets the level of the water level in the washing tub, and is connected to any one of the input terminal groups A to C like other human-powered switches.

Further, the buzzer volume switching unit 90 is configured to switch the notification sound in steps of dog, small, and off, and the water supply port 100 is a joint for connecting a hose from the water supply here and supplying water. This corresponds to

When the start button 60 is pressed in the above configuration,
The ALU section determines that the pause state has been released, and the number display tube Q displays, for example, 28 minutes as shown in FIG.

A signal to open the water supply valve to supply water is also output.

Although it is now in operation mode, if you wish to freely change the washing, rinsing, and spin-drying times, all you have to do is operate the button on the time change section 50, and press the button with the arrow pointing to the left. The button with the arrow pointing to the right will shorten the time.

The six types of cycles in the fully automatic cycle switching section 30 have specifications that not only have lengths of time for each step but also switch the strength of the water flow.

For example, selecting the 1st, 2nd, 5th, and 6th cycles will result in a strong water flow, the 3rd cycle will have a medium water flow, and the 4th cycle will have a soft water flow.

Table 1 shows the above relationship.

As shown in Table 1 above, six typical cycles are set by combining water flow, washing time, rinsing time, and spin-drying time depending on the degree of dirt or type of clothing.

Here, the power and economy shown in Figure 6 are determined by the length of time for each process, and the length of the display band in Figure 5 indicates the actual length of the set time. .

FIG. 6 shows the details of program switching, which is related to partial selection for a fully automatic cycle.

The actual setting is determined by an AND signal between each step of the selected fully automatic cycle and each step of program switching.

Thus, for example, a wash only program for a heavily soiled cycle will result in a 10 minute wash, and a wash only program for a sweater cycle will result in a 2 minute wash.

In addition, the drain/spin program for the normal dirt cycle will drain/spin for 5 minutes, and the drain/spin program for the shirt cycle will drain/spin for 1 minute.

The softener agitation program is common to all fully automatic cycles and is set to perform rinsing for 1.5 minutes, followed by draining and dewatering.

Table 2 is a diagram showing in detail all the steps of one embodiment of the fully automatic cycle.

Each process has been carefully considered to allow the program to proceed efficiently, with slight changes being made to save rinsing water and optimize the required time, depending on the type, quantity and quality of laundry. If you can do it, you can expect a satisfactory result.

However, among the time limits corresponding to each process, the portions for which actual figures are not available cannot be uniformly determined because they vary depending on water supply and drainage conditions.

For the water supply for washing, the pressure switch 5W170 (described later) is set to L-+.
The time required for switching to the H signal t1 is insufficient, and tla is calculated using this tl, the time T1 required for shower dehydration during rinsing, and the time required for shower dehydration during rinsing, which will be described later. Similarly, the time T2, which is the basis of the process T3, becomes insufficient.

Furthermore, the time t2 required for the pressure switch 5W170 to switch to the H-4-L signal during drainage is still insufficient, and the second time tla is also insufficient.

The water supply process includes shower dehydration during washing and rinsing,
and water supply for storage or rinsing, and where it is located during rinsing.

When determining the water supply information by calculating T1 and T2, it is more accurate to take it from a position as close to each as possible, so T1 is processed from the information of tl and T
2, processing is performed from the information of tla.

In other words, the water supply for the washing process may be supplied by the user using a bucket, etc., and accurate information may not be obtained. It is desirable to understand and process this data.

FIG. 7 is a suggested cross-sectional view for explaining the supply and drainage conditions in an easy-to-understand manner.

In the same figure, 110 is a water supply valve installed in the panel section described above, 120 is an outer tank for storing water, 130 is an inner tank that rotates at high speed during dehydration, and 140 is for stirring water flow during washing and rinsing. 150 is a drain valve for draining water in the tank; 160 is a tube for detecting pressure connected to a small chamber of the outer tank 120; 170 is a pressure switch SW for detecting and determining pressure; A tube 160 is connected and the water level can be adjusted by the water level switching unit 80 and set to the optimum value.

There is a predetermined water level in the inner tank 130, and the outer tank 1
20 From the lower side, L, Hl, H,...

Four levels of water levels for H3 can be determined.

By setting the water level switching unit 80, three specified water levels of H1 to H3 are determined, and for each water level, when the water level reaches L, which indicates that drainage has progressed almost to completion, the pressure switch 5W170 switches to H+L. Change.

During water supply, when the water level reaches H1 to H3, the pressure switch 5
W170 is switched to L-+H.

Figure 8 is a graph showing the time required to reach the specified water level when the amount of water supplied changes. The results of calculating the water injection rinsing time using this value are shown by a dashed line and a broken line.

Normally, it can be used if the water supply capacity is around 7.5117'mtπ, and if it is at least 517vu'n, the time required will be longer, but if it is allowed, it should be within the usable range. I can do it.

According to the graph in A above, at a high water level, there is a range of 1.8 minutes to 7.4 minutes for full water, and normally, a satisfactory shower dehydration rinsing effect can be obtained with 1/4 of the specified water flow value. Since this is known experimentally, T1 calculated based on the above time ranges from 0.45 minutes to 1.85 minutes, and on the other hand,
If the water amount is 1.5 times the specified water value, the final rinse concentration of the detergent is guaranteed, so similarly, T2 calculated based on the above time ranges from 2.7 minutes to 11.1 minutes. become.

Similarly, according to the above graph, in the case of low water level, there is a range of 1.3 minutes to 5.3 minutes for full water, and T1 calculated based on this is 0.33 minutes. ~1.33 minutes, T
2 has a width of 1.95 minutes to 7.95 minutes.

Based on the above relationship, the following values are set.

Whether the water supply source has a water supply capacity of 7.5 l/*n or more is determined by setting T, = 5 minutes, and if the water is full within T4, it can be determined that the water supply capacity is 7.5177/INπ or more.

If it is determined that the water supply source is less than 513 /vttπ and cannot be used, T
.

=8 minutes.

However, in the case where the time until the water becomes full is abnormally short, the set time limit To is set to 1 minute, and if it is less than 1 minute, a new representative value T is determined as a very standard value. This is corrected by resetting the time as 23 minutes.

Figures 9 and 10 are flowcharts showing the operation during the water supply process from the start until the water is filled and proceeding to the next step, which corresponds to the operation method according to the present invention.
It includes relevant parts.

That is, as shown in the figure, after the start, the time limit T is corrected to 0, and then water supply is started.

Specifically, the contents of the designated address of the ROM section are read and processed by the ALU section, and the water supply valve 11 in the output terminal group is sent from the ACC section.
A water supply valve ON signal is output to the terminal connected to 0, and this ON signal is transmitted to the pressure switch SW1γ of the input terminal group
This continues until the terminal signal of 0 changes from L to H.

During this water supply, a time limit T keeps ticking to measure the time required until the tank is filled with water.

At this time, in the unlikely event that the water supply is cut off or frozen, or if you forget to open the faucet and operate the system, no matter how many minutes pass, water will not flow in and you will not be able to fill up the system.

Also, even though I am trying to collect water, the drain valve 15
0 etc., if it is not well sealed and the outflow is greater than the inflow, the water level will not increase and it will not become full no matter how much time passes.

In other words, when there is a malfunction (abnormality) related to water supply, etc.
A certain set time limit TC1 (8 minutes according to FIG. 8) is set, and if the water does not become full within the above To, a final determination of abnormality is made and the operation is stopped.

Here, the reason for the final judgment and condition is that before that,
This is because the above-mentioned determination point T4 is provided, and a check function is provided here to notify that the water flow is poor before the final determination is made.

If it is determined that water flow is poor at the determination point T4, an abnormality will be displayed.

Specifically, T is displayed as shown in 8 in FIG.

If the determination unit determines that there is an abnormality, a sounding device such as a speaker or buzzer is used to notify the user.

The constants To and T4 are included in the program in advance and stored in the ROM section.

When using a semiconductor device such as a microcomputer, the processing procedure and judgment logic are stored in the ROM section, and the processing procedure is stored from the corresponding address in the ROM section through the ACC section from the ALU section, which has a judgment function. You will have to find out.

Similarly, the process to be carried out after it is determined that there is an abnormality is determined from the address in the ROM section where the process is stored, and outputs include turning on a lamp, sounding a buzzer, and suspending operation.

The above set time limit T.

When the water becomes full before T<To, and the pressure switch 5W170 switches from L to H, the ROM section is called to determine the next process.

Of course, if the pressure switch 5W170 does not become H, the water supply process is repeated until it becomes To.

By determining the time T required for the tank to be filled with water, the level of water flow can be determined, and the next step should be taken.

Here, first, if the above-mentioned T(tl) is abnormally short, countermeasures are required.

In other words, if the water reaches the specified water level before starting operation (for example, by pumping up the remaining hot water in the bathroom with a bucket, etc.), the full water signal will be activated the moment you turn on the switch and start operation. is entered, and the instruction control unit PS instantly determines that water supply has been completed.

It would be inconvenient to process the time T required for filling up with water and use it for subsequent calculations.

Therefore, we canceled this and, as mentioned above, set a new representative value as the general average value (3 minutes according to Figure 8).
At the same time, as described later, this value is replaced with
This is used for subsequent calculations.

This is an application example of the so-called optimal control rinsing method.
Regarding items that have been sorted by water supply rinsing time, one of the essential methods for adopting the above-mentioned optimal rinsing method is that if the water supply time required is abnormally short, do not incorporate this information internally and use an alternative method. This replaces the value with a very average value.

Regarding the effectiveness of this sorting, with so-called automation, countermeasures are needed in case of manual operation, and in order to obtain satisfactory rinsing performance even in the case of manual operation, processing under the worst conditions must be established. However, there is a lower limit set time limit for the minimum time, and even if any abnormal operation is performed, average rinsing performance is guaranteed.

The following is a general explanation of the subsequent steps according to the above using the flowchart shown in FIG.

That is, next, using the above T, T1. The time limit of T2 is calculated by multiplying by a constant obtained from experiment.

The calculation is performed in the ALU section, and the result is stored in the RAM section.

Next, the rinse power is set from the manual switch,
Discrimination and multiplication procedures will be performed according to standard and economizing conditions.

In other words, in the case of strong rinsing, the calculation processing is 1.5 times that of T2, and in the case of saving, the calculation processing is 0.5 times that of T2.

The result is carried over to FIG. 10 and processed as T3.

First, a correction is made for the case where T3 is small.

In other words, as mentioned above, there are large variations in the calculated value of T, and in the case of the shortest setting, the water injection rinse is 1
Sometimes it's just a matter of minutes.

In order to perform rinsing efficiently, it is necessary for the detergent contained in the laundry to be sufficiently leached out and diluted.
The time T6 required for this is normally 3 minutes.

From the above, if you move on to the next step after rinsing with water has been completed for about a minute, it means that the dilution has proceeded with insufficient dilution, which will cause a problem.

Therefore, only when the water injection time T3 is 3 minutes or less, a new pre-rinsing time is set so that the insufficient water is filled in advance of the water injection rinsing.

Next, if T3 is relatively long, countermeasures are required.

The present invention takes this measure and guarantees the subsequent progress and finish.

Therefore, the present invention relates to setting the maximum time limit of T3 calculated from the water supply process control process.

In Figure 9, T is T. If the time limit is close to or less than , and strong rinsing is selected, the time will be multiplied by 225, resulting in a value close to 18 minutes.

In order to remove dirt from cloth and rinse it thoroughly, this is achieved by applying mechanical force to the cloth using water flow generated by a pulsator, but even though it is thoroughly washed and rinsed, it is a problem if the cloth is damaged.

Therefore, it is better to minimize the time during which the pulsator operates.

Taking this reality into account, the maximum length would be nearly 18 minutes.

The above control method cannot be said to be a completely rational method for dealing with damage to cloth.

Therefore, in the present invention, after calculating T3, the constant T7 and T3 are compared, and if T3 is larger than T7, T3 is newly changed to T3.
7, taking care not to allow T3 to exceed T7, and performing water rinsing for a maximum of T7.

Further, comparing T3 and T7, if T3 is larger than T7, the rotation of the pulsator is stopped for the time period T3-T7, and water is exchanged by simultaneously draining water and water injection.

The purpose of this water exchange is to equalize the rinsing performance, to minimize cloth staining when the pulsator rotates for a long time, and to ideally equalize the rinsing performance.

As T7, 8 minutes, which has a proven track record, is used compared to conventional timer cycles.

After the above processing, the pre-rinsing time, water injection rinsing time, and shower dehydration rinsing time are set and stored in the RAM section, and the water supply process is completed and the process proceeds to the next step.

As described above, the time required for the second water supply shower dewatering rinse, the time required for the water pouring rinse, etc. are determined based on the water supply time in the water supply process.

As the program progresses further and the drain at the beginning of the rinsing process is completed, the time for the second drain can be estimated by analogy.

Therefore, immediately after the start of operation, set average values for uncertain parts such as water supply and drainage, make a budget for the overall remaining time, and after the start of operation, perform replacements at accurate times based on confirmed information. , it is possible to display the total remaining time as it is corrected.

Moreover, in order to efficiently perform water rinsing, functions such as automatic setting of water rinsing time are effectively utilized and incorporated into the remaining time display, so this method can be said to be related to revolutionary optimally controlled automatic washing. .

The present invention has been explained above in relation to a series of overall configurations incorporating the method of the present invention, but in short, the present invention is as follows:
The present invention is intended to enrich the peripheral and related programs and their configurations for concrete implementation of rinsing related to the optimal control method, and when the time required to reach the specified water level in the water supply process is relatively long, , I replaced it with a constant,
It can be said that this invention has excellent practical effects as it takes care not to adversely affect fabric damage.
