(イ) 産業上の利用分野
本考案は脱水槽内で注入脱水によるすすぎを行
なう洗濯機に関する。[Detailed description of the invention] (a) Industrial application field The present invention relates to a washing machine that performs rinsing by injection dehydration in a dehydration tank.
(ロ) 従来の技術
脱水槽の上部を開閉するカバー(内蓋)に水受

あるから、上下の金型への喰い付きがよく生じ、
離型しにくいことがある。また、底面が上向きに
反り、底面周辺部だけで注水することに成る。(b) Conventional technology Generally, a water receiving device is provided on the cover (inner lid) that opens and closes the top of the dehydration tank, and water is injected into the dehydration tank through this device. In some cases, it is not possible to provide a water receiving device, so the shape of the cover itself must be designed in place of a water receiving device. The cover is preferably made of a transparent or semi-transparent material so that the inside of the tank can be easily viewed, but in any case, it is an integrally molded product made of resin. When molding such a cover, since the bottom surface of the cover is relatively flat, it often bites into the upper and lower molds.
It may be difficult to release from the mold. In addition, the bottom surface curves upward, and water is poured only around the bottom surface.
このすすぎの場合注水された水は、遠心力によ
り内から外に出ていくことになるので、脱水槽の
中央に注水するのが最も有利である。 In the case of rinsing, the injected water will flow from the inside to the outside due to centrifugal force, so it is most advantageous to inject water into the center of the dehydration tank.
そこで、この点に基づいた形状の水受容器が実
開昭55−156680号公報(第6図参照)にて開示さ
れている。同図に於いて、51は略中央部に設け

受部、53は前記給水受部52から略円弧状に延
びて前記注水孔51に連通する通水路、54…は
前記給水受部52に受けた水を分散して放出する
多数の散水孔である。 Therefore, a water receiver having a shape based on this point is disclosed in Japanese Utility Model Application Publication No. 55-156680 (see FIG. 6). In the figure, 51 is a water inlet provided approximately in the center, 52 is a water supply receiving part that receives water from a water source, and 53 is a substantially circular arc extending from the water supply receiving part 52 and communicating with the water inlet 51. The water passages 54 are a large number of water sprinkling holes that disperse and discharge the water received by the water receiving portion 52.
然しながら、この水受容器は、中央の注水口5
1からの水がシヤワー状でないので、例えば脱水
槽の中央に散水筒を立設し、この散水筒内に水を
注水するものであればこれでもよいが、散水筒で
なく直接脱水物に注水する場合、注水が一点に集
中され、その部分に膜を形成してしまい水が下方
まで浸透しにくいものである。 However, this water receiver is located at the central water inlet 5.
Since the water from step 1 is not in a shower shape, for example, if you set up a water sprinkling tube in the center of the dehydration tank and pour water into the water sprinkling tube, this is fine, but it is better to pour water directly into the dehydrated material instead of through the water sprinkling tube. In this case, the water is concentrated in one point and forms a film in that area, making it difficult for water to penetrate downward.
また、通水路53を形成する各側壁53aが垂
直に立設されているために水が衝突時の勢いで上
方や外方に飛び跳ねる恐れがある。 Further, since each side wall 53a forming the water passage 53 is vertically erected, there is a risk that water may splash upward or outward due to the force of the collision.
(ハ) 考案が解決しようとする問題点
本考案は偏りの少い注水を可能にすると共に、
中央部分での注水量を確保してすすぎ作用を補償
するものである。(c) Problems to be solved by the invention This invention enables water injection with less bias, and
This ensures the amount of water injected into the center to compensate for the rinsing action.
更に、水が脱水物の下方まで浸透し易く且つ水

Then, the dehydration tank 6 first rotates clockwise for about 50 seconds, then stops for about 40 seconds after braking and inertia for about 30 seconds.
This is then repeated a maximum of 5 times and a minimum of 3 times as one cycle. On the other hand, rinsing water is continuously introduced into the safety cover 11 from the supply path 20, and falls from there into the dehydration tank 6 through the water injection holes 14, etc. Here, the rinsing water passing through the supply channel 20 is rectified by the rectifying ribs 21, and when the flow rate and flow velocity are small, it flows along the supply channel 20 and is uniformly distributed from the entire area of the inlet 12 onto the bottom surface of the cover. pervades. but,
When the flow rate and flow velocity are large, the flow tends to be biased toward the right side wall of the supply path 20 beyond the rectifying ribs 21 (see the one-dot chain line in FIG. 5), and is introduced from the inlet 12 as it is. At this time, the uneven rinsing water coming out of the inlet 12 heads toward the dispersion protrusion 16 which is also arranged unevenly, collides with it, and is dispersed almost equally to the left and right.
Then, it is uniformly diffused onto the bottom surface, pools in a thin layer, and falls from the water injection holes 14. Dehydration tank 6
The rinsing water inside the tank is directly absorbed by the laundry at the top of the tank, and then gradually penetrates into the middle part where it is absorbed. On the other hand, water flows down through the upper and lower water injection channels 29 and 24 to the middle and lower laundry items.
7 Water is absorbed from... Also, the rinsing water is in the concave groove 26.
Water flows down and is absorbed. Dehydration hole 7 of dehydration tank 6...
is present only in the upper part and the rinsing water does not drain out, and the water holes 27 are formed more densely in the lower part.
Rinse water is well absorbed by the laundry in the middle and lower parts.

ず)を設ける。 In this embodiment, the diameter of the water injection holes 14 is φ2.5 at the peripheral portion and φ3 at the other portions, and the amount of water supplied to the safety cover 11 is approximately 12 l/min. Also,
A transparent outer cover (not shown) is provided on the top of the safety cover 11 so that the bottom surface of the cover and the inside of the dehydration tank 16 can be visually observed.
本実施例では導入口12への逆流を防ぐために
導入口12の下部口縁が高さ(m)を有してい
る。 In this embodiment, the lower edge of the inlet 12 has a height (m) in order to prevent backflow to the inlet 12.

ある。 Further, in this embodiment, since the introduction port 12 is formed in the inclined peripheral side wall of the cover 11, molding can be performed using a mold with upper and lower holes. The vertical width (l) of this inlet 12 is set so that the amount of water flowing into the safety cover 11 does not overflow outside the cover.
更に、本実施例では安全カバー11の底面に円

の役目も果す。 Furthermore, in this embodiment, a circular stepped portion 15 is formed on the bottom surface of the safety cover 11 to facilitate mold release. Further, the stepped portion 15 also serves as a reinforcing rib to prevent the bottom surface from warping up even if a flat bottom surface is formed.

は確保できるのである。 Also, if the washing machine is slightly tilted when installed,
The water introduced into the safety cover 11 tends to flow toward the inclined side, resulting in uneven water injection into the dehydration tank 6. However, in this embodiment, no matter which direction it is tilted, the stepped section 15 located in the center fulfills the water storage function, and the water inlet 14 is also provided here, so the rinsing water is not necessarily poured into the stepped section 15. The water is introduced first, and from there it is supplied to the center of the dehydration tank where it is most effective. In other words, even if the washing machine is installed slightly tilted, the amount of rinsing water can be ensured.
更に、本実施例では安全カバー11の周側壁を

突時の勢いで上方及び外方にはね、カバー11外
に飛び出やすいのである。 Furthermore, in this embodiment, the peripheral side wall of the safety cover 11 is inclined outward at an angle of about 60 degrees, for example. This is to prevent water flowing out from the inlet 12 with a high flow rate from overflowing by dispersing it in the circumferential direction. That is, if the circumferential wall is made vertical, for example, the water is likely to splash upwards and outwards due to the force of the collision, and to easily fly out of the cover 11.
