Description

Detailed Description of the Invention [Object of the Invention] (Field of Industrial Application) The present invention relates to a washing machine in which an agitator in a tub is driven intermittently.

(Prior Art) Traditionally, washing machines have been equipped with a large agitator as an agitator that generates water flow in the tub.

Some devices are designed to perform washing or rinsing, or both, by being driven intermittently.

In this type of washing machine, the motor is alternately energized and de-energized based on a motor control signal from a control circuit, and the agitator is intermittently driven by intermittent operation. In this case, the strength of the water flow differs depending on the energization time and power-off time for the motor, and in this type of washing machine, the energization time and power-off time are preset in the control circuit at several predetermined energization times and predetermined power-off times. The time is stored and retained, and the strength of the water flow is selectively set by selecting and setting the predetermined energization time and de-energization time.

(Problems to be Solved by the Invention) By the way, the strength of the water flow is changed not only by the degree of dirtiness of the laundry and the amount of laundry, but also by the type of fabric of the laundry. However, in recent years, there has been a tendency for the number of types of cloth to increase, and due to such circumstances, there has recently been an increasing need for users to arbitrarily set the strength of the water flow.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable the user to set the strength of the water flow as desired, and to provide fine-grained control according to the degree of dirtiness of the laundry, the type of cloth, etc. The purpose of the present invention is to provide a washing machine that can perform a washing operation.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides for intermittent operation of a stirring body in a tank by alternately energizing and de-energizing a motor based on a motor control signal from a control circuit. In the motor which is driven to perform washing or rinsing or both, the control circuit is provided with energization/deenergization time setting means for arbitrarily setting the energization time and de-energization time of the motor, respectively. This is a characteristic feature.

(Function) The strength of the water flow generated by intermittent driving of the stirring body changes depending on the length of the energization time and the length of the power-off time of the motor. Therefore, the strength of the water flow can be arbitrarily set by appropriately setting the energization time and the energization time for the motor using the energization/disconnection time setting means.

When the arbitrary water flow setting switch 21 is operated after this, the display content of the time display 12 is changed to the time display (see operation order "9" in Fig. 4), and the arbitrarily set energization time is changed. T1 and the power-off time To are stored and held in a predetermined area of the aforementioned memory of the control circuit 2. Therefore, the stored energization time T1 and the energization time To are:
