Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic washing machine equipped with an automatic detergent dosing device.

BACKGROUND OF THE INVENTION In a conventional automatic washing machine, when washing heavily soiled laundry, the user first sets it to wash only, and when it seems that only the washing has finished, the user goes to the washing machine again. Take measures such as drainage and dehydration. The user then adds detergent again and starts the wash cycle. Furthermore, if a user wants to wash clothes by adding detergent many times, the user has to visit the washing machine many times each time to add detergent.

Problems that the invention aims to solve However, with conventional washing machines, when washing heavily soiled laundry, it is necessary to add detergent several times. indispensable,
The problem was that it was very inconvenient to use.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to save the user the trouble of visiting the washing machine cabinet many times, improve the automation rate of the washing machine, and further improve the cleaning effect.

Means for Solving the Problems In order to achieve the above object, the automatic washing machine of the present invention is provided with a washing operation number setting means for setting the number of washing operations, and water and detergent are added for the set number of times.

The washing and draining operations are repeated, and after a set number of cycles are completed, the next process is started.

Function The above configuration automatically supplies water and adds detergent multiple times, saving the user the trouble of visiting the washing machine many times and adding detergent each time. Improve automation.

In fact, the cleaning effect is improved by performing the washing operation multiple times.

Example Embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, reference numeral 1 denotes an outer washing tub, and an inner tub 2 for dewatering and washing is provided inside. A pulsator 3 is rotatably installed at the bottom of the dewatering/washing inner tub 2, and the dewatering/washing inner tub 2 and the pulsator 3 are rotated by a drive motor 8. Reference numeral 9 denotes a washing number setting means, which is formed by a group of switches 1 to N, and is set by the user pressing the switch corresponding to the desired number of washings n (1≦n≦N) before starting washing. , set the number of washes. The output of the washing frequency setting means 9 is inputted to the control means 10. The control means 1o is constituted by a microcomputer, and inputs the outputs of the water level detection means 11, water level setting means 13, etc. in addition to the washing frequency setting means 9, and controls the detergent injection valve driving means 5 to open and close the detergent injection valve 15. The flow of the detergent in the detergent storage tank 4 into the washing tub is controlled. The trench water supply valve driving means 6 and the drain valve driving means 7 are controlled to operate the water supply valve 14.
and opens and closes the drain valve 16 to control the inflow of water into and outflow of water from the washing tub.

Further, the drive motor 8 is controlled to rotate and stop the pulsator 3 and the dewatering/washing inner tub 2.

Next, the operation of this embodiment will be explained with reference to FIG. 2, which shows the control of the microcomputer 1°.

After putting the laundry into the washing tub, the user sets the water level setting means 1.
3 to set the water level and operate the switch 12 to start washing. By this operation, the microcomputer 1Q opens the water supply valve 14 via the water supply valve driving means 6 and starts the inflow of tap water. Furthermore, the detergent injection valve 15 is opened via the detergent injection valve driving means 5 to start adding the detergent in the detergent storage tank 4. Next, the amount of detergent corresponding to a preset water level is stored in the microcomputer 1o, and when the amount of detergent added becomes the same value as the stored value, the pesticide injection valve 15 is closed to complete the detergent injection. Furthermore, when the water level reaches the set value,
The water supply valve 14 is closed, the pulsator 3 is rotated by the drive motor 8, and washing is started. The rotation of the pulsator 3 continues until the set washing time ends, and at the same time as the washing ends, the drain valve 16 is opened to start draining the water in the washing tub. A draining time is set in accordance with the set water level, and when the draining time reaches the set value, the draining is deemed to have ended, and the spin-drying tub/washing inner tub 2 is rotated by the drive motor 8 to start spin-drying. At the same time as the set dewatering time ends, the rotation of the dehydrating tub/washing inner tub 2 is stopped and the drain valve 16 is closed to complete the dewatering. Next, it is detected whether the laundry has been washed the number of times set by the number of washing times setting means 9. Here, if washing has not been performed the set number of times, the process returns to the initial water supply and detergent input amount, and the above-mentioned operations are repeated again. Then, when the laundry has been washed a set number of times, the next rinsing step is started.

With the above-described operation, even if the user wants to perform the washing operation multiple times, he only needs to set the number of times at first, and can concentrate on other housework until the washing is completed.

The amount of detergent added for the second and subsequent times may be smaller than the amount of detergent added for the first time, thereby making it possible to save the amount of detergent.

In addition, although this example shows an automatic washing machine that performs washing and dehydration in one tank, it can also be applied to a two-tank washing machine that performs washing, rinsing, and dehydration separately, so that the process from washing to rinsing can be automated. A similar effect can be obtained by doing the following.

Effects of the Invention As described above, according to the present invention, when a user washes heavily soiled laundry, the user can add detergent multiple times and wash the laundry multiple times. 1 eliminates the need to visit the store and only requires setting the number of washing and detergent injections when starting washing, which improves the automatic rate.Furthermore, even in normal washing, it is possible to set the number of washings and detergent injections multiple times. It is possible to improve the cleaning rate.
