Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for operating a washing machine, and in particular, the present invention relates to a method for operating a washing machine, and in particular, a method for supplying water to a specified amount of water into a washing tub. This invention relates to a method of operating a washing machine in which, when the value is insufficient, a pre-rinse is performed to compensate for the shortage before the water injection rinsing, and then the water injection rinsing is performed for a time determined by calculation processing.

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 and it is difficult to complicate the applied operations and control. On the other hand, if a computer such as a microcomputer is used to program the timer device and the timer device is computerized, it becomes possible to exchange information with the washing machine itself, making it easier to use, and also allowing the program to be set to the optimum conditions to be relaxed and smooth. This is something that can be expected to work. 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 the water supply mode is different depending on the water supply source. It is greatly influenced by water pressure.

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 with water while pouring water, rinsing with water up to the specified level without pouring water, and rinsing without pouring water.
There are three types: rinsing, further storing water to a specified level, then rinsing by sprinkling water in a shower during dehydration, 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, so the rinsing time must be determined to satisfy the rinsing performance in areas with low water pressure.

However, as mentioned above, in the current situation where the time limit is determined by a mechanical cam switch, it is necessary to uniformly determine the time limit for water injection rinsing, etc., regardless of the amount of water supply time. However, this method had the disadvantage of using more water than necessary.

As mentioned above, conventional washing machines did not have a function to judge the water supply capacity of the water supply source, so under the worst conditions,
The time cycle had to be determined so that the rinse performance could be satisfied.

Furthermore, since the supply capacity of the water supply source is not known, even if you want to use water that does not meet the specified amount for other purposes than just rinsing, the amount of water supplied will vary greatly, and such situations will be difficult. control was not possible or the precision was insufficient.

In other words, in other applications mentioned above, when hot water is used to wash permanently pressed products (for example, dress shirts, etc.), if you suddenly rinse with cold water during rinsing, wrinkles may occur, and the hot water may not be used in the washing tub. While a certain amount remains in the tank, supply a certain proportion of cold water to gradually lower the temperature.
There is a process called cool-down, and it has been found that it is not necessary to supply water up to a specified amount of water, but only a certain percentage of the specified amount of water. Also, at the beginning of spin-drying, if the laundry is shifted to one side of the spin-drying tank, it will become unbalanced and spin-drying will not be possible. There is a control method called the residual water activation method, which starts dewatering from a state where water has accumulated to a fairly good level, and it has been confirmed that it is highly effective. The amount of water at this time was less than the specified water amount, and was in a range that could not be controlled using existing pressure sensors. Furthermore, in connection with the above-mentioned water supply mode, when adopting the optimal rinsing method, it is necessary that the determined set time for water injection rinsing be less than a certain time, that is, sufficient rinsing efficiency can be obtained and dilution of the detergent can be completed. However, in cases such as those below, separate measures are required.

Based on the above, there has been a long-awaited invention for a control method that can stably supply a certain proportion of water to a specified amount of water.

The present invention solves the drawbacks under the above-mentioned circumstances and satisfies the demand, and in order to perform optimal rinsing, the water supply time in the water supply process of the washing machine can be adjusted internally in the computer. The first prerequisite purpose of the present invention is to provide a method for operating a washing machine in which the values are temporarily stored and the stored values are used to perform optimal rinsing during the process.

A second purpose is to enrich peripheral and related programs for concretely realizing rinsing according to the above-mentioned optimal control method, and to provide a configuration related to corresponding means.

In other words, this latter function can be said to be one of the functions required when adopting an automatic determination method for the rinsing process, which is not uniformly determined, in correlation with the first objective above. This is intended to provide a guarantee in the event that the originally calculated time limit for water injection rinsing falls short of a certain set value.

In other words, for example, in the conventional rinsing time, the rinsing time is set to a certain setting and time limit (for example, 3 minutes), and the set time is guaranteed, but with the automatic determination method,
If the capacity of the water supply source is high, the setting may be less than 3 minutes.

However, in order to uniformly perform the dilution process of dispersing and displacing detergent with water while washing clothes containing detergent, there is a minimum amount of time that must be secured.
If this is not taken into consideration, sufficient performance will not be guaranteed.

Therefore, if the water injection rinsing time calculated based on the capacity of the water supply source is less than a certain set time limit, it is necessary to guarantee the rinsing performance by rinsing without injecting water or changing to a pre-rinse to make up for the shortage. It is what it is.

The method for operating a washing machine according to the present invention includes:
In a method of operating a washing machine that performs each washing process according to the set order, supplies water up to a specified amount in the washing tub, and performs a predetermined rinse process, the time required for water supply is measured. The time required for water injection rinsing, calculated by multiplying this value by a constant, is divided into cases in which it is less than a certain period of time and cases in which it is not. A pre-rinse is performed prior to water injection rinsing for the time period of this value, and then a water injection rinse is performed for the calculated time required for water injection rinsing, and in the latter case, only for the calculated water injection time period. The system is designed to perform rinsing with water.

Next, an embodiment of the method for operating a washing machine according to the present invention will be described. For ease of understanding, it will be explained that the method solves the other drawbacks of the conventional method mentioned above and meets the requirements. The overall configuration including other configurations according to the
A method of operating a washing machine having a series of configurations will be explained in detail by referring to a method in which the method according to the present invention is incorporated.

First, FIG. 1 shows a fully automatic washing machine used in an embodiment of the method of operating a washing machine according to the present invention, which has a computer such as a microcomputer, that is, a computer library, and is configured to perform settings. This diagram schematically shows the internal functions of the instruction control unit PS that causes each washing process to be carried out in the specified order, including the relationship with input/output terminals, and the double arrows indicate data buses or address buses. It is.

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 internal block of the instruction control section PS will now be described.

First, input/output terminals A to 1 (C and D are input/output terminals.

) is the ALU section (Nithmetjc Logic Un
if, arithmetic logic unit), Acc
The AL (accumulator) stores calculation results and processing data, and has functions such as calculation and judgment.
The U section and the U section constitute the central part of the instruction control section PS. Note that c in the above Acc section is the carry F/F.
, C2 is a carry evacuation F/F.

Here, F/F is a flip flop. Then, c of the carry F/F is the carry (
This is an F/F that indicates the presence or absence of carry (carry) and borrow (borrow). For addition, c=1 has a carry, c=0 has no carry, and for subtraction, c=1 has a borrow, and c= 0 indicates no borrowing. Further, the carry-save F/F c2 is an F/F that temporarily saves the contents of the carry F/F during interrupt processing (INT). The ROM section (read-only memory) is a storage section in which procedures for operating the washing machine, setting conditions for judgment, rules for processing various information, etc. are loaded in advance.

A counter for addressing the program stored in this ROM section is performed by a PC section (program counter) written below the ROM section.

The STACK section (stack register) contains subroutines and
This is used to save the contents of the upper PC section when there is a call or a request for interrupt processing.

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

The TIMER section (timer) can set a time limit by a timer set command, and by stacking these time limits, each process stored in the ROM section is executed on time.

When the interrupt control circuit section receives an interrupt processing request signal INT, it can interrupt the instruction in progress.

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

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

In the figure, terminal No. 21 (Vss) (hereinafter referred to as terminal 21. The same applies to the others) and terminal 41 (VGG) are related to a power source that drives the instruction control unit. The terminal groups A, B, C and D mentioned above are each made up of four signal terminal groups and control the input of the indicator and control agent PS, and the terminal groups E, F, G are also in charge of inputting the indicator and control agent PS. .

In addition, terminal 1 (CL) and terminal 42 (CLo) are CLOCK GE, which controls the timing of the operation of the instruction and control unit.
The external terminal of the LC resonant circuit for the NERATOR section, terminal 6 (INT), is the interrupt processing request input terminal, terminal 7 (R
ES) is a reset input terminal, and terminal 20 (TE
ST) 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 numerical display tube and R is a 12-digit display tube of L, to L, 2. This is a progress display section consisting of progress display lamps and the like.

That is, as an example regarding the output of the Acc part mentioned earlier, a total of 15 terminals of terminals E, G, date, and 1 related to output are used as a display, and the 2-digit numerical display tube Q is used for all processes. This displays the remaining time, and uses light emitting diodes or light-emitting diodes.The progress display to notify the progress status is performed by the 12 progress display lamps L to L, 2 as described above. However, generally a long-life light emitting diode is used.

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 numeral display tube Q mentioned above.

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 message consisting of a horizontal bar and the letter E, as shown in Figure C, will be displayed as an error message. It is to be 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 plaque, 2 is a power switch, 30 is a fully automatic cycle switching section, 40 is a program switching section, 5 is a time change section, 60 is a start button, and 70 is a , a pause button, 80 a water level switching section, 90 a buzzer volume switching section, and 100 a water supply port.

Then, fully automatic cycle switching section S, ~ S6
The display corresponds to the display of severe dirt, normal dirt, light dirt, sweater, dress shirt, and diaper corresponding to S and S6 in FIG. 6, which will be described later. Displays 1 to V in FIG. 7 similarly correspond to 1 to V in FIG.
This corresponds to the display for rinsing, draining/dehydration, and softener.

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 controls the power switch 20' and the main circuit to be turned on and off. be.

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 GS. Furthermore,
Program switching section 4, washing, rinsing, and dewatering processes are set so that they can be selected in combination, and time changing section 5, washing, rinsing, and dehydrating each process independently. This is related to a switch for manual settings that can be changed based on an idea. As mentioned earlier, the progress indicator R consists of 12 progress indicator lamps, as shown in the figure, 5 for the washing process, 4 for the rinsing process, and 3 for the draining 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, an input signal (not shown, but connected to the input terminal group A to D in the instruction and control section) is transmitted to the instruction and control section. This input is judged by the ALU section, and the address in the ROM section indicating how it will be processed is indicated, so a command is issued to the PC section to call up the address, and the R
The contents of the corresponding address are called from the OM section to the ALU section, and instructions for appropriate operations are outputted through the Acc section. Since the input button at the top is the longest program, all 12 progress display lamps in the progress display section R 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, and the pause mode is the opposite of the pause button 7 and the start button 60.
If this button is not pressed, the operating state will continue. Further, the water level switching unit 80 is an input switch that sets the height of the water level in the washing tub, and is connected to one of the input terminal groups A to C like the other input switches.

Further, the buzzer volume switching unit 90 is configured to switch the notification sound in steps of high, low, and off, and the water supply port 100 is a port for connecting a hose from the water supply to supply 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 numeric display tube Q
For example, as shown in Figure 5, 28 minutes is displayed.

A signal to open the water supply valve to supply water is also output. This means that it is now in operation mode, but if
If you wish to freely change the washing, rinsing, and spin-drying times, you can simply operate the buttons on the time change section 50.The left arrow button extends the time, and the right arrow button extends the time. This will save time.

The six types of cycles in the fully automatic cycle switching section 301 have specifications that not only have lengths of time for each step but also switch the strength of the water flow.

For example, if you select the 2nd, 5th, and 6th cycles for the 1st cycle, the combination will be a strong water flow, the 3rd cycle will be a medium water flow, and the 4th cycle will be a soft water flow. FIG. 6 shows the above relationship. As shown in the figure, six representative cycles are set by combining water flow, washing time, rinsing time, and spin-drying time depending on the degree of dirt or the 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. 7 shows the details of program switching, which is related to a fully automatic cycle and a partial selection.

The actual setting is determined by an AND signal between all steps 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. Softner Toyofu. . Gram is common to all fully automatic cycles, and is set to drain and dehydrate after 1.5 minutes of pre-rinsing. FIG. 8 is a diagram showing in detail all steps of an 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 finish.

However, among the time limits corresponding to each process, the portions that do not contain actual numbers cannot be uniformly determined because they vary depending on water supply and drainage conditions. For the water supply for washing, the time t required for the pressure switch SW170 to switch from L to day signal, which will be described later, is undefined, and this t is used to calculate t, a, and the rinsing process, which will be described later. Required time T for shower dehydration during dehydration rinsing, and
Therefore, the time T2, which is the basis of T3 in the water injection rinsing step, is similarly indefinite.

Further, the time t2 required for the pressure switch SW170 to switch from H to L signal during draining is still undefined, and the second time t is also undefined. Note that the water supply process includes water supply for shower dehydration during washing and rinsing, water supply for storage or water injection rinsing, and water injection rinsing.
When determining the water supply information by calculating T, and T2, it is more accurate to search from a position as close to each as possible, so T, is processed from the first information, and L is , t, and a are processed.

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 the immediately preceding data.

FIG. 9 is a schematic 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 above-mentioned panel part, 120 is an outer tank for storing water, and 1
30 is an inner tank that rotates at high speed during dehydration; 140 is a washing;
150 is a drain valve that drains the water in the tank; 16 is a tube for detecting pressure that is connected to a small chamber in the outer tank 120; 170 is a tube for detecting pressure; With the pressure switch SW to judge, the tube 160
is connected, and the water level is adjusted by the eight water level switching units, allowing it to be set to the optimum value.

There is a predetermined water level in the inner tank 130, and from the bottom of the outer tank 120, the water level can be determined in four stages: L, day, day 2, and day 3. Depending on the settings of the water level switching unit 80,
Three specified water levels for days 3 to 3 are determined, and for each water level, when the water level reaches L, which indicates that drainage has proceeded to near completion, the pressure switch SW170 switches from H to L.
When water is being supplied, when the water level reaches the level on days 3 to 3, the pressure switch S
W170 is switched from L to day. Figure 10 shows
This is a graph showing the time required to reach the specified water level when the water supply amount changes. The results of calculating the water injection rinsing time using this method are shown by the dashed line and the dashed line.

Normally, it can be used if the water supply capacity is around 7.5〆/min, and if the capacity is at least 5〆/min, the time required will be longer, but if it is allowed, it will be within the usable range. You can put it in.

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. This has been experimentally proven.

Therefore, T, calculated based on the above time, is 0.
The range is from 45 minutes to 1.88 minutes, and on the other hand, the specified water flow value is 1.
．． If it is 5 times, the final rinsing concentration of the detergent is guaranteed, so similarly, T2 calculated based on the above time is:
The range is 2.7 minutes to 11.1 minutes.

Similarly, according to the graph above, when the water level is low, there is a range of 1.3 minutes to 5.3 minutes for full water, and T, calculated based on this, is 0. 33 minutes to 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 min/min or more is determined by setting T4 = 5 minutes, and if the water is full within T4, it can be determined that the water supply capacity is 7.5 min/min or more.

Judgment that the water supply source cannot be used if it is less than 5 evenings/min is L = 8
minutes. Additionally, if the time taken to fill the water is abnormally short, T5 is set to 1 minute, and if it is less than 1 minute, correction is made by setting T5 to 3 minutes, which is a very standard value. Bye.

FIG. 11 is a flowchart showing the operation during the water supply process from the start until the water is filled and proceeding to the next step.

As shown in the figure, after starting, the time limit T is corrected to 0 and water supply is started later.

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 output 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 SW17 of the input terminal group
The terminal signal of 0 continues from L to day.

During this water supply, a time limit T advances moment by moment 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 amount of discharge is greater than the amount of inflow, the water level will not increase and 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 time limit To (8 minutes according to FIG. 10) is set, and if the water is not filled within the above To, it is finally determined that there is an abnormality and the operation is stopped.

Here, the reason for the final judgment and condition is that before that,
This is because a determination point that is L is provided, and a check function is provided 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, the display is as shown in C of FIG.

T. If it is determined that there is an abnormality in the determination location, a notification is made using a sound source such as a speaker or a buzzer. Constants of the set time limit related to the determination time limit, To and T4, are included in the program in advance and stored in the ROM section.

When a semiconductor device such as a microcomputer is used, 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 performed after it is determined that there is an abnormality is determined from the address in the ROM section where the process is stored, and the output is to turn on a lamp, sound a buzzer, or stop operation. . When the water becomes full before the set time limit To reaches the above-mentioned time limit (that is, T<To) and the pressure switch SW170 switches from L to R, the ROM section is called to determine what to do next. Of course, if pressure switch SW170 does not turn on, To
The water supply process is repeated until the 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. First, T(t
．． > is abnormally short, countermeasures are required.

In other words, if the water has reached the specified water level before you start operation (for example, if you use a bucket to pump up the remaining hot water in the bathroom), the full water signal will appear the moment you turn on the switch and start operation. In an instant, the instruction and control unit determines that the water supply has been completed. Since it would be difficult to process T as is, in this case, it is replaced with a general average value (3 minutes according to FIG. 10). That is, next, the above T
is calculated by multiplying T,,T2 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 input switch,
Discrimination and multiplication procedures will be performed according to standard and economizing conditions.

In other words, for strong rinsing, 1.3 notes of L, and for economy, 0.0 notes of T2. Calculation processing of kalon is performed. The result is the first
This is carried over to Figure 2 and is treated as the water injection time t.

Here, if the above-mentioned time T3 is short, that is, if it falls short of a certain set value as described later, countermeasures are required.

The present invention takes this measure and guarantees the subsequent progress, and in short, makes corrections. In other words, as described above, there is a large variation in the calculated value of L, and in the case of the shortest setting, water injection rinsing may be completed in about one minute.

In order to perform rinsing efficiently, it is necessary for the detergent contained in the laundry to seep out and be diluted.
The time T8 required for this is normally 3 minutes. From the above, after rinsing with water for about a minute,
If you move on to the next step, the dilution will proceed with insufficient dilution, which will cause a problem. Therefore, only if the eyebrow stroke 3 during water injection is 3 minutes or less of time T6, the insufficient amount should be added before rinsing with water. It is now possible to set a new pre-rinsing time so that the pre-rinsing process can be performed.

This is an application example of the so-called optimal control rinsing method.
One of the essential methods for adopting the above-mentioned optimal rinsing method is to set the determined water rinsing time limit for a certain period of time (to achieve rinsing efficiency and detergent dilution). In the following cases, the time for rinsing is set as a pre-rinsing time to fill up the shortage without adding water, prior to rinsing with water.

Regarding this sorting effect, even if the water injection rinsing time is automatically determined according to the water supply capacity, it has a judgment function as a measure to ensure the minimum necessary pulsator rope time. If the time limit determined from the calculation is less than the set value, Takaazusa's time can be added by the amount that is less than the set value.

Moreover, this additional amount is nothing but an addition that is set to be performed prior to water injection rinsing in order to improve the rinsing effect.

In addition, in the above, the rinsing is controlled by time, but as is already clear from a lot of information, there are methods to monitor the rinsing from the detergent concentration, methods to measure the resistance value, and transparency. Methods for measuring this have also been developed on a laboratory scale.

It is meaningful to add that these technical methods can be used together to develop a more effective method. In other words, it is clear that if such a sensor is realized, it will be possible to correct the completion of rinsing in addition to the time limit element determined by water supply, T2. Furthermore, when pre-rinsing is performed prior to pre-rinsing, extending the pre-rinsing until the concentration of detergent seeping out of the cloth reaches a certain level will further ensure the effectiveness of the pre-rinsing and enable water rinsing to be carried out effectively. There are also benefits. After the above treatment, rinsing time,
Water injection rinsing time and shower dehydration rinsing time are RA
It is set and stored in section M, and the process proceeds to the next step after the water supply process is completed.

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

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, regarding uncertain areas such as water supply and drainage,
It is possible to display the total remaining time by setting an average value, making a budget for the overall remaining time, and then, after the start of operation, changing stations at accurate times and making corrections based on the sequentially confirmed information.

Moreover, in order to efficiently perform water rinsing, this method utilizes functions such as automatic setting of water rinsing time and incorporates them into the remaining time display. I can say that. This total remaining time display is performed by changing the contents of the RAM section to the latest information, and also takes care to correct abnormal values so that the budget and actual calculations do not deviate significantly. It is included.

The user can tell how many minutes it will take to complete the process from the display, which can be an easy-to-use feature that the user does not have in conventional products. 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 specifically realizes rinsing related to an optimal control method. This is in line with the enhancement of peripheral and related programs and their configurations, and guarantees are provided in the event that the water injection rinsing time calculated based on the water supply time limit falls short of a certain set value. This invention can be said to have excellent practical effects.
