なつていた。(Prior art and its problems) In general, in a washing machine, water splashes occur when rinsing with water, and the splash is larger when the water flow is strong, and when the water flow is set to be strong when rinsing with water. If the distance between the water level during rinsing and the top of the washing tub was small, the splashed water would leak over the top of the washing tub and leak onto the floor, etc.

The structure is equipped with water flow switching means to achieve the intended purpose.

以下図面に示した本案の実施例について詳細に
説明する。(Example) An example of the present invention shown in the drawings will be described in detail below.

を検知することができる。 As shown in FIG. 2, the detector 8 has a light emitting element 14 and a light receiving element 15 arranged facing each other on both sides of the overflow pipe 7, and optically detects the presence or absence of overflow water. That is, the light from the light emitting element 14 passes through the detection window 16, the inside of the overflow pipe 7, and the detection window 16, and reaches the light receiving element 1.
5, and when the light is blocked by the overflowing water droplets 17, the output level of the light receiving element 15 decreases. Therefore, the presence or absence of overflow water can be detected based on the output level of the light receiving element 15.

弱水流に切換わることになる。 In the above configuration, when moving to the water injection rinsing process, the sequence control unit 12 keeps the water supply valve 3 ON via the water supply valve control unit 7, as shown in the flowchart of FIG. The motor 5 is driven to reverse left and right through the motor control unit 10 according to the water flow operation program, and a preset rinsing water flow is created by reversing the pulsator 4. When the rinsing water starts to overflow from the overflow drain port 1a, the detector 8 detects the overflow water and outputs a signal indicating that there is overflow water. Then, the sequence control unit 12 determines the signal from the detector 8, switches from the preset water flow to a weak water flow, controls the motor 5 according to the weak water flow operation program, and controls the pulsator 4. A weak water flow is created by reversing the flow, and subsequent water injection rinsing will be performed using the weak water flow. Therefore, if the strong water flow is set in advance, the strong water flow will be switched to the weak water flow when overflow water is detected.

This will be explained according to the diagram. In Figure 4, A is the highest water level set during washing or rinsing, and B is the highest water level set during washing or rinsing.
indicates the water level during water pouring and rinsing, a indicates the distance between the water level A and the top of the washing tub 1, and b indicates the distance between the water level B and the top of the washing tub 1.

びはねは小さく、距離ｂは弱水流で水の飛びはね

よりも充分に小さくでき、洗濯槽１自体を小型化
できるものである。 Experimental results have shown that the splashing of water during rinsing is greatest when the laundry load is less than half of the rated load under strong water flow. by the way,
In conventional washing machines, rinsing is performed using a preset water flow, so if a strong water flow is set, the rinsing is performed using a strong water flow. Therefore, in order to prevent water from splashing out of the washing tub, the above distance b must be determined assuming the case where the splashing of water is the largest.
The distance b becomes larger. On the other hand, in this case, as shown in the above embodiment, when overflow water is detected during water injection rinsing, the flow is switched to a weak water flow, and the water injection rinsing is always carried out with a weak water flow, so water splashing is avoided. The distance b can be determined based on the assumption that a weak water flow causes a large splash of water, and it can be made sufficiently smaller than the conventional one, allowing the washing tub 1 itself to be made smaller.
尚、本実施例において、水位Ａは強水流で排水
口１ａより洗浄液が流出しない範囲内で設定し、
距離ａは注水すすぎ時強水流で洗濯物が定格容量
の半分以下の時に水が飛び出さないように設定す
るものである。 In this example, the water level A is set within a range where the cleaning liquid does not flow out from the drain port 1a with a strong water flow.
The distance a is set to prevent water from splashing out when the laundry is less than half of its rated capacity with a strong water flow during rinsing.
本案は上記しかつ図面に示す実施例のみに限定

適宜変形して実施できること勿論である。例えば

はオーバーフロー水の有無を検知できるものであ
ればよい。 It goes without saying that the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with appropriate modifications within the scope of the invention. For example, the detector may be one that detects water using electrodes, an element whose impedance changes when it gets wet, or the like, as long as it can detect the presence or absence of overflow water.
（考案の効果）
以上の如く本案の構成によれば、注水すすぎは
水の飛び出しの恐れのあるオーバーフロー検知時
のみ、弱水流にするようにしたので、小型の洗濯
槽を採用しても負荷によつては強水流でも注水す
すぎを行うことが出来、しかも水の飛び出しがな
くなる。(Effects of the invention) As described above, according to the structure of the present invention, the water flow is weak during rinsing only when an overflow is detected where there is a risk of water splashing out, so even if a small washing tub is used, the load will be reduced. In the end, it is possible to perform water injection rinsing even with strong water flow, and there is no need for water to splash out.
