Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a fully automatic machine used in ordinary households.

Conventional Technology Conventionally, this type of fully automatic washing machine has a water flow selection button that changes the water flow to a strong or weak state, a wash time setting button, a rinse selection button, a spin time setting button, and a washing button.

A select button is provided to set the process to be executed from each step of rinsing and spin-drying, and a washing time setting button,
Each process was controlled according to the set time by pressing the rinse switch button and dehydration time setting button.

Problems to be solved by the invention ``However, the conventional configuration had the following problems.

■ The rinsing time is fixed, so if you want to rinse twice and finish within 30 minutes, even if you shorten the paper dehydration time, the washing time is only about 3 minutes, which is too short. .

■ Washing time could not be set in 1 minute increments.

■ It was not possible to determine the total time for each process according to the user's time.

The present invention is intended to solve these problems, and aims to improve usability for users.

Means for Solving the Problems In order to achieve the above object, the present invention calculates and determines the washing time, rinsing time, number of rinses, and dehydration time by combining the button input regarding the washing time and the total time input. A control means is provided.

Function: With this configuration, each washing, rinsing, and spin-drying process is automatically set by inputting the total washing time, thereby improving usability.

Embodiment An embodiment of the present invention will be explained with reference to FIGS. 1 to 4. In FIG. 1, reference numeral 1 denotes a water flow input detection function, which detects the water flow set by the water flow button. 2 is a select input detection function, which allows the user to set a course (washing only, washing/rinsing only).

It detects rinsing and spin-drying only, and spin-drying, washing, rinsing and dehydration). 3 is a rinsing input detection function, which detects whether the user has selected reserve rinsing or overflow rinsing. 4 is a total time input detection function, which detects the time input by the user. 5 is a time allocation judgment means, which judges the inputs of the select input detection function 2, the rinse input detection function 3, and the total time input detection function to judge the washing time, rinsing time, number of rinses, and dehydration time. Then, the data is sent to the control means 6 to operate the washing machine.

A specific circuit of this embodiment will be explained with reference to FIG.

In Figure 2, 7 is the operation button, 7a is the water flow switching button, 7b is the rinse switching button, 7C is the select button to set the course, 7d is the button for the 10's for total time setting, and 7e is the 1 This is the digit button. 7f is a start/pause button, and pressing this button starts and pauses. Reference numeral 8 denotes an input section into which output signals from the operation buttons are input. 9 is where calculations and time allocation decisions are made based on the input data, and 1
゜ is an output unit that outputs the time determined by calculation. 11 is a micro combination meter, and 12 is a washing machine operated by the output from the output section 10.

The control of the microcomputer 11 will be explained with reference to FIG.

The signal input to the key by pressing the operation button is calculated by the calculation time allocation determining section 9. That is, step 1
When the key is pressed in Step 3, first, in order to know the course selected in SELECT, it is determined in Step 14 whether or not to wash the clothes. If washing is not performed in step 14, it is determined whether to rinse in step 15. If rinsing is not performed in step 15, it is determined in step 16 that only dehydration is required, and dehydration is performed for the input time. Step 14
When washing is to be carried out in step 14', the water flow is determined, and then in step 17, it is determined whether or not to perform rinsing. If rinsing is not to be performed, it is determined in step 18 that the operation is for washing only, and washing is performed for the input time. If rinsing is performed in step 17, it is determined whether dehydration is to be performed in step 19. If you do not want to dehydrate, proceed to step 20.
It is determined whether the total washing time is more than a minute. Here, the value a includes the water supply and drainage time for washing and rinsing, and considering this water supply and drainage time as a constant value, and assuming that one water supply and drainage time is T, sT if there are two rinses, and 1 rinse and 1 rinse. In the case of times, it becomes 3T and 1. -5T or a-3T
This is the time for washing, rinsing, and intermediate dehydration, which is determined in step 2o in order to distribute this time without difficulty.

Although a is determined in step 2o, this value is set to a standard cycle. In other words, as shown in Figure 4, the washing time is d minutes, the rinsing time is 0 minutes, and the intermediate dehydration time is 1 minute.
This is the standard data, and when d+(e+f)x2)a-5T is
x(1-k) (k is an arbitrary coefficient), and if this does not apply, d+e+f)a-3T then (d+e+f)x(1-
k) (k is an arbitrary coefficient) and calculate to obtain an appropriate cycle. Also, if it deviates from this, d ten (e
+f)X2 (for a-5T, (d+e+f)x(1+
x) (X is a real number), and calculate to extend all times proportionally by a multiplier of 1+x, or alternatively, display an error and reset.

As another example, by changing the magnification, d+(e+f
)X2:) When a-sT, dXo, 9+eX0.5
There is also a method of calculating +fX0.4 so as not to remove the main ones. Also, as another example,
On the other hand, there is a method of increasing the magnification of the main items and calculating them. In this embodiment, the water flow is varied using a pulsator, and the washing time and water flow are combined to allocate time so that cleaning performance can be achieved even in a short time. If it is less than a minute in step 20, it will be rinsed once in step 21, and washing and rinsing (rinsing once) will be performed. If it is more than a minute in step 2°, rinse twice in step 22 and perform washing and rinsing (rinsing twice).

In step 23, if dehydration is performed in step 19, it is determined whether the input time is longer than b minutes. As shown in Figure 4, this b minute means water supply and drainage is done 6 times or 4 times, so b-6T or b-4T is used for washing,
The criteria for determining whether the conditions for rinsing and dehydration are optimal are the same as in a above, and if it is less than or equal to b, the process moves to step 24, and if it is more than or equal to b, the process moves to step 25. Step 24 is washing, rinsing (rinsing once),
This is a dehydration process, and step 26 is a washing, rinsing (rinsing twice), and dehydration process. step 26 is step 16
When rinsing is performed, it is determined whether the total time is 0 minutes or more. As shown in Figure 4, this 0 minutes means that water supply and drainage are performed 5 times or 3 times, so c-sT or
Determine whether c-3T is the optimal condition for rinsing and dehydration,
This criterion is the same as above, and if it is below C,
Step 270 Rinse 1 times, if it is C or higher, step 28
Rinse twice. In step 27, rinsing (rinsing once) and dehydration are performed, and in step 28, rinsing (rinsing twice) and dehydration are performed. And these are step 29
The washing machine outputs a signal to operate the washing machine, allowing users to use the washing machine at their own time.

Effects of the Invention As described above, according to the present invention, the following effects can be obtained.

■ The washing time, rinsing time, intermediate spin-drying, and spin-drying times can be shortened proportionally according to the time set by the user.
You can set different times by applying different magnifications.

■ Even if the washing time is short, it is possible to ensure the washing function by changing the strength of the water flow from the pulsator.

■ The washing machine allocates the time set by the user and
By controlling the water flow, spin speed, etc., you can use calculations to set a course that satisfies the cleaning performance and spin dry performance.

■ If the user inputs the total washing time, it is possible to set a course for washing, rinsing, etc.

As described above, usability for the user can be improved.
