Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a washing machine capable of supplying and rinsing laundry while causing water supplied into the washing tub to overflow from the washing tub.

[Prior Art] FIG. 3 shows a schematic configuration of a washing machine of this type.

In the case of performing water supply rinsing with the above washing machine, the operation button on the operation panel (not shown) is operated to preset the water level, water flow, rinsing time, etc. in the washing tub 1, and press the start button. Then, the water supply valve 2 is opened and the water supply into the washing tub 1 is started. When water is supplied to the predetermined level in the washing tub 1, water supply rinsing is performed with a preset water flow for a predetermined time. In this case, water supply to the washing tub 1 is continued with the water supply valve 2 opened, and the motor 3
As a result, the pulsator 4 is rotationally driven.

Then, the water above the predetermined level in the washing tub 1 overflows from the upper opening of the bellows hose 5 and is discharged to the outside through the drain hose 6.

FIG. 4 shows a time chart in the case of performing the water supply rinsing as described above.

In addition, A in the figure shows the time when the water supply up to a predetermined level is completed.

[Problems to be solved by the device]

However, when rinsing with water as described above,
Immediately after the water is supplied to the predetermined level in the washing tub 1 and the rotation of the motor 3 is started, the detergent contained in the laundry 7 in the washing tub 1 is hardly eluted into the washing water. Continuing the water supply into the washing tub 1 in such a state means that the laundry 7 in the washing tub 1 is sufficiently rinsed and the upper portion of the bellows hose 5 is kept until the detergent begins to be eluted into the washing water. Clean water containing no detergent will be discharged from the opening, wasting water.

Therefore, an object of the present invention is to provide a washing machine having a function capable of efficiently performing water supply rinsing without wastefully discharging water.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the main means adopted by the present invention is, as its gist, a washing machine capable of supplying and rinsing laundry while causing water supplied into the washing tub to overflow from the washing tub. In the case of performing water rinsing, after supplying water to a predetermined level sufficient to perform rinsing in the washing tub, stop temporary water supply, perform rinsing for a predetermined time, and then start water supply again, The washing machine is provided with a control means for rinsing water while overflowing water from the washing tub.

[Action]

In the washing machine configured as described above, when the water supply is rinsed, when the washing water is supplied to the washing tub to a predetermined level sufficient for performing the rinsing, the water supply to the washing tub is stopped. , Rinsing is performed for a predetermined time. Then, for example, when a sufficient amount of the detergent contained in the laundry is eluted in the washing water, the water supply to the washing tub is restarted, and the washing water sufficiently filled with the detergent overflows from the washing tub. Is discharged to the outside.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. In addition, the following embodiment is an example in which the present invention is embodied, and does not limit the technical scope of the present invention.

Here, FIG. 1 is a block diagram showing a control system of a washing machine according to an embodiment of the present invention, and FIG. 2 is a time chart in the case of rinsing water with the washing machine.

As shown in FIG. 1, the washing machine according to this embodiment supplies water to a predetermined level sufficient to perform rinsing in the washing tub 1 (see FIG. 3) when rinsing with water. The control device 8 (control means) is configured to stop the temporary water supply, perform rinsing for a predetermined time, then restart water supply, and perform water rinsing while overflowing water from the washing tub 1.

The control device 8 includes a microcomputer, a memory, a power supply, an interface, and the like,
This is for operating and controlling the motor 3, the water supply valve 2 and the like based on the conditions set by the operator operating the operation buttons on the operation panel 9. The procedure of water supply rinsing as described above is pre-programmed in the memory.

Subsequently, a procedure for performing water supply rinsing using the washing machine configured as described above will be described with reference to FIGS. 1 and 3.

First, the operator operates the operation buttons on the operation panel 9 to preset the water level, the water flow, the rinsing time, etc. in the washing tub 1, and presses the start button. Then, the water supply valve 2 is turned on and opened by the control device 8, and the washing tub 1
Water supply to the inside begins. When water is supplied to the washing tub 1 at a predetermined level sufficient to perform rinsing and rinsing, the water supply valve 2 is turned off and the water supply to the washing tub 1 is stopped. Then, the motor 8 is started by the control device 8 and the pulsator 4 is rotationally driven, so that a predetermined time (a time indicated by B in FIG. A sufficient time to allow the contained detergent to elute in the wash water. Experiments have shown that a time of about 1 minute is suitable).

Approximately one minute has passed after the water supply valve 2 was stopped, and when a sufficient amount of the detergent contained in the laundry 7 was eluted in the wash water, the controller 8 turns on the water supply valve 2 and Water supply to the washing tub 1 is started again.

As a result, the washing water containing a sufficient amount of detergent overflows from the washing tub 1 through the upper opening of the bellows hose 5, so that the water supply and rinsing are performed very efficiently.

As described above, the amount of water saved by temporarily stopping the water supply to the washing tub 1 was about 15 l per minute.

[Effect of device]

As described above, the present invention provides a washing machine capable of rinsing water by supplying water to the washing tub while overflowing the water from the washing tub. Control to supply water to a predetermined level sufficient for rinsing, stop temporary water supply, perform rinsing for a predetermined time, then restart water supply, and perform water supply rinsing while overflowing water from the washing tub A washing machine characterized in that means are provided. Therefore, in the washing machine according to the present invention, by providing the step of positively rinsing with a sufficient amount of water to perform the rinsing even in the rinsing with water, the laundry can be washed without exerting a great force. The laundry detergent can be sufficiently eluted without damaging the water, and the water is not wasted.
Water can be rinsed efficiently.
