以下、図１３から図１７に基づいて、一般的なトップロード洗濯機の構成について説明する。
Hereinafter, the configuration of a general top load washing machine will be described with reference to FIGS. 13 to 17.
洗濯機本体１０２は、内部に洗濯槽１０１を回転自在に収納し、洗濯機本体１０２の上部には、洗濯機本体１０２の上部全体をほぼ覆う上部筐体１０３が装着されている。上部筐体１０３の略中央には、上部筐体１０３に一体に成形され、洗濯槽１０１の上方に向けて下方向に伸延して構成した衣類投入口１０４を形成している。上部筐体１０３には、衣類投入口１０４の上方全体を覆う蓋体１０５を開閉自在に装着している。洗濯槽１０１は、モータ１１０により、回転、停止させる。
The washing machine main body 102 rotatably accommodates the washing tub 101 therein, and an upper housing 103 is attached to the upper portion of the washing machine main body 102 to substantially cover the entire upper portion of the washing machine main body 102. At approximately the center of the upper casing 103, there is formed a clothes inlet 104 which is integrally formed with the upper casing 103 and extends downward in the washing tub 101. A lid 105 that covers the entire upper part of the clothing inlet 104 is openably and closably attached to the upper housing 103. The washing tub 101 is rotated and stopped by the motor 110.
上部筐体１０３には、衣類投入口１０４の近傍位置に、洗剤を収容する洗剤収容ケース１０６を引き出し自在に配設している。洗剤収容ケース１０６の上方には、流路構造部１０７を構成し、流路構成１０７により水道水を導いて、洗剤収容ケース１０６の各部に流下する構成としている。流路構造部１０７は、流路構造部１０７の上面を構成し、流路構造部１０７からの水漏れを防止する流路構造部上面１０７ａと、流路構造部１０７の下面を構成し、洗剤収容ケース１０６に供給する水を流下する流路構造部下面１０７ｂとからなる。洗剤収容ケース１０６の下方には、洗剤溶解手段１０８を構成している。洗剤収容ケース１０６により、水道水と洗剤とが混合され、洗剤水溶液１０９が作られる。
A detergent accommodating case 106 for accommodating a detergent is arranged in the upper housing 103 in a position near the clothes inlet 104 so as to be drawn out. A flow path structure 107 is formed above the detergent storage case 106, and tap water is guided by the flow path configuration 107 to flow down to each part of the detergent storage case 106. The flow path structure portion 107 constitutes an upper surface of the flow path structure portion 107, and constitutes a flow path structure portion upper surface 107a for preventing water leakage from the flow path structure portion 107 and a lower surface of the flow path structure portion 107. It is composed of a flow path structure lower surface 107b through which water supplied to the housing case 106 flows down. Below the detergent containing case 106, detergent dissolving means 108 is configured. The detergent containing case 106 mixes tap water and detergent to form an aqueous detergent solution 109.
流路構造部上面１０７ａと洗剤溶解手段１０８とは、一体に構成し、洗濯槽１０１側に開口し、洗濯槽１０１の反対側で有底になるように構成している。
The upper surface 107a of the flow path structure portion and the detergent dissolving means 108 are integrally formed, open toward the washing tub 101 side, and have a bottom on the opposite side of the washing tub 101.
これにより、水道水圧が高く、流路構造部１０７を流れる流量が多い場合でも、洗剤収容ケース１０６、および、洗剤溶解手段１０８から溢れた洗剤水溶液１０９が、洗濯機本体１０２や上部筐体１０３に溢れ出ることを防止するので、モータ１１０などの電気部品
に水がかかって絶縁不良になることを防止している。
As a result, even when the tap water pressure is high and the flow rate flowing through the flow path structure 107 is large, the detergent accommodating case 106 and the detergent aqueous solution 109 overflowing from the detergent dissolving means 108 are transferred to the washing machine main body 102 and the upper housing 103. Since it is prevented from overflowing, it is prevented that electric components such as the motor 110 are splashed with water to cause insulation failure.
洗剤収容ケース１０６には、衣類投入口１０４とは反対側に位置する一方の端に第１の排水部１１１を形成し、洗剤水溶液１０９は、第１の排水部１１１から洗剤溶解手段１０８に排水している。
The detergent containing case 106 has a first drainage portion 111 formed at one end located on the side opposite to the clothes inlet 104, and the detergent aqueous solution 109 is drained from the first drainage portion 111 to the detergent dissolving means 108. doing.
洗剤溶解手段１０８には、衣類投入口１０４側に位置する一方の端に第２の排水部１１２を形成している。洗剤溶解手段１０８表面を流下した洗剤水溶液１０９は、第２の排水部１１２から衣類投入口１０４に排水される。
The detergent dissolving means 108 has a second drain portion 112 formed at one end located on the side of the clothes inlet 104. The detergent aqueous solution 109 that has flowed down on the surface of the detergent dissolving means 108 is drained from the second drainage section 112 to the clothes inlet 104.
洗剤溶解手段１０８は、第１の排水部１１１から第２の排水部１１２に向かって下降傾斜している。第２の排水部１１２は、衣類投入口１０４より外側で、かつ、洗濯槽１０１の衣類投入口１０４側の開口端の洗濯槽開口部内壁１１３より内側に配置される。
The detergent dissolving means 108 is inclined downward from the first drainage portion 111 toward the second drainage portion 112. The second drainage section 112 is arranged outside the clothes insertion port 104 and inside the washing tub opening inner wall 113 at the opening end of the washing tub 101 on the clothes insertion port 104 side.
これにより、洗剤水溶液１０９は、第２の排水部１１２から洗濯槽開口部内壁１１３の内側に排水されるので、洗剤水溶液１０９が洗濯槽１０１と洗濯機本体１０２との間を伝って、モータ１１０などの電気部品に水がかかって絶縁不良になることを防止している。
As a result, the detergent aqueous solution 109 is drained from the second drainage portion 112 to the inside of the washing tub opening inner wall 113, so that the detergent aqueous solution 109 is transmitted between the washing tub 101 and the washing machine main body 102, and the motor 110 is discharged. It prevents the electrical parts such as water from being exposed to water and resulting in poor insulation.
洗剤溶解手段１０８は、保持部材１１４により下方から保持されている。保持部材１１４は、洗剤溶解手段１０８の他、図示しないリード線、センサーなどの電気部品をあらかじめ組み立てて、ユニット状態にした後、図示しないツメ、ねじ等により、上部筐体１０３に取り付けられる。
The detergent dissolving means 108 is held from below by a holding member 114. The holding member 114 is attached to the upper housing 103 by means of tabs, screws, etc. (not shown) after previously assembling the detergent dissolving means 108, electric parts (not shown) such as lead wires, sensors, and the like into a unit state.
これにより、保持部材１１４、洗剤溶解手段１０８他をユニット状態にして上部筐体１０３に組み立てられるので、容易に製造できる。
As a result, the holding member 114, the detergent dissolving means 108 and the like can be assembled into the upper housing 103 in a unit state, which facilitates manufacturing.
図１４に示すように、洗剤溶解手段１０８には、リブ１２０を洗剤溶解手段１０８の有底側から開放側の方向に伸延して配置している。洗剤収容ケース１０６の底部には、スリット１２１を開口し、スリット１２１内にリブ１２０を挿入している。
As shown in FIG. 14, the detergent dissolving means 108 has ribs 120 extending from the bottomed side of the detergent dissolving means 108 toward the open side. A slit 121 is opened at the bottom of the detergent containing case 106, and a rib 120 is inserted into the slit 121.
リブ１２０とスリット１２１との間の隙間に洗剤水溶液１０９を通すことにより、洗剤を効率よく溶かし、洗浄性能を向上している。また、使用者が、洗剤収容ケース１０６を出し入れするたびに、リブ１２０がスリット１２１内を摺動するので、リブ１２０とスリット１２１との間に洗剤が固着し、目詰まりすることを防止できる。また、洗剤溶解手段１０８は、第１の排水部１１１から第２の排水部１１２に向かって、下降傾斜するとともに、リブ１２０は、洗剤溶解手段１０８の有底側から、開放側の方向に伸延して配置しているので、洗剤溶解手段１０８を作成するとき、金型の抜き方向とリブ１２０の伸延方向を同じにすることができ、容易に成型することができる。
By passing the detergent aqueous solution 109 through the gap between the rib 120 and the slit 121, the detergent is efficiently dissolved and the cleaning performance is improved. In addition, since the rib 120 slides in the slit 121 every time the user inserts and removes the detergent containing case 106, it is possible to prevent the detergent from being fixed between the rib 120 and the slit 121 and clogging. Further, the detergent dissolving means 108 inclines downward from the first drainage portion 111 toward the second drainage portion 112, and the rib 120 extends from the bottom side of the detergent dissolving means 108 toward the open side. Since the detergent dissolving means 108 is formed in such a manner, the die drawing direction and the extending direction of the ribs 120 can be made the same, and the detergent dissolving means 108 can be easily molded.
図１５に示すように、洗剤溶解手段の摺動面１３０上に洗剤収容ケースの摺動面１３１を摺動自在に支持している。流路構造部１０７の左右に配置した流路構造部のツメ１３５ａ、１３５ｂは、洗剤収容ケース１０６を最も引き出したときに、洗剤収容ケースの縁部１３４に当たるように配置している。
As shown in FIG. 15, the sliding surface 131 of the detergent containing case is slidably supported on the sliding surface 130 of the detergent dissolving means. The claws 135a and 135b of the flow path structure portion arranged on the left and right of the flow path structure portion 107 are arranged so as to contact the edge portion 134 of the detergent storage case when the detergent storage case 106 is most pulled out.
これにより、洗剤収容ケース１０６内に洗剤を投入する際に、流路構造部１０７のツメ１３５ａ、１３５ｂと洗剤収容ケース１０６の縁部１３４とを当接させることによって洗剤収容ケース１０６の位置を規制して、がたつきを無くして洗剤を入れやすくしている。洗剤収納ケース１０６を手入れする際は、洗剤収容ケース１０６を引き出した後、斜め上方に持ち上げて洗剤収容ケース１０６の縁部１３４を流路構造部１０７のツメ１３５ａ、１３５ｂからはずして、洗剤収容ケース１０６を取り外せるようにしている。
Accordingly, when the detergent is put into the detergent containing case 106, the position of the detergent containing case 106 is regulated by bringing the tabs 135a and 135b of the flow path structure portion 107 into contact with the edge portion 134 of the detergent containing case 106. And it is easy to add detergent by eliminating rattling. When cleaning the detergent accommodating case 106, after pulling out the detergent accommodating case 106, the detergent accommodating case 106 is lifted obliquely upward to remove the edge portion 134 of the detergent accommodating case 106 from the tabs 135a and 135b of the flow path structure 107, and the detergent accommodating case 106 is removed. The 106 is removable.
従来の別の洗濯機、例えば、フロントローディングの洗濯機を図１６に示す。流路構造部１０７のツメ１３５が流路構造部１０７の中央、洗剤収容ケース１０６に対向する面に設けられ、洗剤収容ケース１０６を一番引き出した際に、洗剤収容ケースのツメ１３７に当接する。洗剤収容ケース１０６は、縦長の形状をしている。
FIG. 16 shows another conventional washing machine, for example, a front-loading washing machine. The claw 135 of the flow channel structure 107 is provided in the center of the flow channel structure 107, on the surface facing the detergent storage case 106, and contacts the claw 137 of the detergent storage case when the detergent storage case 106 is pulled out most. .. The detergent accommodating case 106 has a vertically long shape.
これにより、洗剤収容ケース１０６のツメ１３７に当てる位置まで引いたとき、洗剤収容ケース１０６の後方部分の左右壁面を、洗剤溶解手段１０８の内壁で位置を規制して、がたつきを無くすことにより、洗剤を入れやすくしている。洗剤収容ケース１０６を取り外すときは、洗剤収容ケース１０６のツメ１３７を弾性的に保持する洗剤収容ケース１０６のはり部３６を押し下げ、洗剤収容ケース１０６のツメ１３７を流路構造部１０７のツメ１３５から外して取り外している。
Accordingly, when the detergent storage case 106 is pulled to a position where it comes into contact with the tab 137, the left and right wall surfaces of the rear portion of the detergent storage case 106 are regulated in position by the inner wall of the detergent dissolving means 108 to eliminate rattling. , Easy to put detergent. When removing the detergent containing case 106, the beam portion 36 of the detergent containing case 106 that elastically holds the tab 137 of the detergent containing case 106 is pushed down, and the tab 137 of the detergent containing case 106 is removed from the tab 135 of the flow path structure section 107. Removed and removed.
図１７に示すように、洗濯槽１０１上方に、衣類にシャワー水１５０ａ、１５０ｂをかける給水手段１５１が設けられている。洗濯槽１０１内の水をポンプ（図示せず）でくみ上げ、加圧して給水手段１５１に送っている。給水手段１５１には、さらに、底面に設けた円形の第１の吐出口１５２と、外周面に略水平方向に開口した第２の吐出口１５３とを有している。第１の吐出口１５２と第２の吐出口１５３の手前には、絞り部１５４を有していて、絞り部１５４により流速をあげている。
As shown in FIG. 17, above the washing tub 101, a water supply means 151 for spraying shower water 150a and 150b on the clothes is provided.

The water supplied from the water supply valve 18 passes through the flow path including the first downflow hole 25 and the second downflow hole 26 in the flow path structure portion 7, and then passes through the flow path throttle portion 42 to form the lateral flow path. Water is supplied to 41. The left and right ends of the lateral flow passage 41 respectively extend downward to form a first water pipe portion 43 and a second water pipe portion 44.
第１の水管部４３と、第２の水管部４４の下端近傍は、球面部４５を有しており、球面部４５は、第１の水管部４３、第２の水管部４４の中心軸を中心に、内面まで略同一半径に形成している。球面部４５の一部は、洗濯槽１側に向けて斜め下方向に開口して、第１の水平開口部４６と第２の水平開口部４７とを形成している。第１の水管部４３と、第１の水平開口部４６は、第１の給水手段４８を構成し、第２の水管部４４と第２の水平開口部４７は、第２の給水手段４９を構成している。
Near the lower ends of the first water pipe portion 43 and the second water pipe portion 44, there is a spherical surface portion 45, and the spherical surface portion 45 has the central axes of the first water pipe portion 43 and the second water pipe portion 44. At the center, the inner surface is formed with substantially the same radius. A part of the spherical surface portion 45 opens obliquely downward toward the washing tub 1 side to form a first horizontal opening portion 46 and a second horizontal opening portion 47. The first water pipe portion 43 and the first horizontal opening portion 46 form a first water supply means 48, and the second water pipe portion 44 and the second horizontal opening portion 47 form a second water supply means 49. I am configuring.
第１の給水手段４８と第２の給水手段４９は、洗剤収容ケース６の左右に隣接して配置される。これにより、第１の水平開口部４６、第２の水平開口部４７から洗濯槽１に向けて、シャワー水５０を洗濯槽１内の洗濯物５５に流す。
The first water supply means 48 and the second water supply means 49 are arranged adjacent to the left and right of the detergent storage case 6. As a result, the shower water 50 flows into the laundry 55 in the washing tub 1 from the first horizontal opening 46 and the second horizontal opening 47 toward the washing tub 1.
第１の水平開口部４６と第２の水平開口部４７は、水管部４３、水管部４４の中心軸を中心にした球面部４５に洗濯槽１側に向けて斜め下方向に開口しており、水管部４３、水管部４４の中心軸を中心に第１の水平開口部４６と第２の水平開口部４７に対して垂直に水が流れる。球面部４５と第１の水平開口部４６と第２の水平開口部４７とは、それぞれ水の噴出方向を決定する付勢手段を構成している。
The 1st horizontal opening part 46 and the 2nd horizontal opening part 47 are opening diagonally downward toward the washing tub 1 side in the spherical part 45 centering on the central axis of the water pipe part 43 and the water pipe part 44. Water flows vertically to the first horizontal opening 46 and the second horizontal opening 47 around the central axes of the water pipe 43 and the water pipe 44. The spherical surface portion 45, the first horizontal opening portion 46, and the second horizontal opening portion 47 respectively constitute urging means for determining the jet direction of water.
洗濯槽１は、モータ１０により、時計方向に回転する第１の回転状態と、反時計方向に回転する第２の回転状態とを備えており、洗い、すすぎの際、給水弁１８が開いて、これらの回転時にシャワー水５０を洗濯槽１内の洗濯物５５に供給している。
The washing tub 1 has a first rotation state in which it is rotated clockwise by the motor 10 and a second rotation state in which it is rotated counterclockwise by the motor 10, and the water supply valve 18 is opened during washing and rinsing. During these rotations, the shower water 50 is supplied to the laundry 55 in the washing tub 1.
これにより、第１の回転状態では、洗濯槽１の左側にある洗濯物５５は、同じく洗濯槽１の左側にある第１の給水手段４８に向かって近づく方向に移動する。同様に第２の回転状態では、洗濯槽１の右側にある洗濯物５５は、同じく洗濯槽１の右側にある第２の給水手段４９に向かって近づく方向に移動する。
Accordingly, in the first rotation state, the laundry 55 on the left side of the washing tub 1 moves in a direction approaching the first water supply means 48 on the left side of the washing tub 1 as well. Similarly, in the second rotation state, the laundry 55 on the right side of the washing tub 1 moves in a direction toward the second water supply means 49 on the right side of the washing tub 1 as well.
第１の水平開口部４６、および第２の水平開口部４７の左右端には、端部開口部５１が形成されている。端部開口部５１は、略円形に形成され、第１の水平開口部４６、および第２の水平開口部４７の縦方向開口寸法より大きい開口寸法に形成されている。第１の水平開口部４６と端部開口部５１、および第２の水平開口部４７と端部開口部５１は、両端部の開口面積の大きい長孔形状に形成される。これにより、ゴムホースの先端を指でつまんで水を扇形に広げて放水する際の、ゴムホース先端開口形状に似た開口形状に形成される。
End openings 51 are formed at the left and right ends of the first horizontal opening 46 and the second horizontal opening 47. The end opening 51 is formed in a substantially circular shape and has an opening size larger than the vertical opening size of the first horizontal opening 46 and the second horizontal opening 47. The first horizontal opening 46 and the end opening 51, and the second horizontal opening 47 and the end opening 51 are formed in a long hole shape having a large opening area at both ends. As a result, an opening shape similar to the opening shape of the tip of the rubber hose is formed when the tip of the rubber hose is pinched with fingers and the water is spread in a fan shape and discharged.
第１の水平開口部４６と、その左右の端部開口部５１とを加えた開口面積Ｓ１は、第１の水管部４３の流路断面積Ｓ２よりも小さく、流路絞り部４２の開口面積より大きく設定している。第１の水管部４３の流路断面積Ｓ２は、横方向流路４１の流路断面積と略同一に設定されている。
The opening area S1 obtained by adding the first horizontal opening 46 and the left and right end openings 51 is smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43, and the opening area of the flow passage throttle portion 42. It is set larger. The flow passage cross-sectional area S2 of the first water pipe portion 43 is set to be substantially the same as the flow passage cross-sectional area of the lateral flow passage 41.
これにより、流路絞り部４２を介して、横方向流路４１、第１の水管部４３、第１の水平開口部４６へと流れる水は、絞られた部分がなく、すなわち流路断面が狭くなるところがなく、流路内の水圧が下がりにくくすることができる。水道水圧がひくく、流量が少な
い場合は、第１の水平開口部４６からのシャワー水５０の速度も小さくなり、第１の水管部４３内の水の減少も遅くなる。
As a result, the water flowing to the lateral flow passage 41, the first water pipe portion 43, and the first horizontal opening portion 46 via the flow passage throttle portion 42 has no narrowed portion, that is, the flow passage cross section is Since there is no place to narrow, it is possible to make it difficult for the water pressure in the flow path to drop. When the tap water pressure is low and the flow rate is low, the velocity of the shower water 50 from the first horizontal opening portion 46 also decreases, and the decrease in the water in the first water pipe portion 43 also slows down.
第１の水平開口部４６と、その左右の端部開口部５１とを加えた開口面積Ｓ１は、第１の水管部４３の流路断面積Ｓ２よりも小さく設定しているので、シャワー水５０の速度より、第１の水管部４３内を流れる流速は、断面積Ｓ２に反比例して遅くなる。第１の水管部４３内の水位による圧力と、シャワー水５０の速度のバランスが取れたところで、第１の水管部４３内の水位が安定し、第１の水平開口部４６には、水位に応じた一定の水圧がかかり続ける。これは、第２の水平開口部４７についても同様である。
Since the opening area S1 including the first horizontal opening 46 and the left and right end openings 51 is set to be smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43, the shower water 50 From the velocity of, the flow velocity flowing in the first water pipe portion 43 becomes slower in inverse proportion to the cross-sectional area S2. When the pressure due to the water level in the first water pipe portion 43 and the speed of the shower water 50 are balanced, the water level in the first water pipe portion 43 stabilizes, and the water level in the first horizontal opening portion 46 becomes A certain amount of water pressure will continue to be applied. The same applies to the second horizontal opening 47.
第１の水平開口部４６には、下半分を構成する顎部５２を有している。顎部５２の内側は、球面部４５の一部を第１の水平開口部４６の縁まで伸延し、流水経路断面積を絞る絞り面５３を有している。顎部５２の外側は、第１の水平開口部４６の縁から第１の水管部４３の伸延方向に対し、下方に後退する後退面５４を有している。これは、第２の水平開口部４７についても同様である。
The first horizontal opening 46 has a jaw 52 that constitutes the lower half. The inside of the jaw portion 52 has a throttle surface 53 that extends a part of the spherical surface portion 45 to the edge of the first horizontal opening portion 46 and narrows the cross-sectional area of the flowing water path. The outer side of the jaw 52 has a receding surface 54 that recedes downward from the edge of the first horizontal opening 46 in the extending direction of the first water pipe section 43. The same applies to the second horizontal opening 47.
洗濯槽１の下方には、洗濯物に回転力を与えて洗浄する攪拌翼５６を有している。攪拌翼５６の下方には、洗濯槽１の開口に向けて放射状のリブを伸延して構成した洗剤溶解翼５７を有している。洗濯運転中は、洗濯槽１は、回転させずに、攪拌翼５６をモータ１０により回転する。これにより、洗剤溶解翼５７も回転する。
Below the washing tub 1, there is a stirring blade 56 for applying a rotational force to the laundry to wash it. Below the stirring blade 56, there is a detergent dissolving blade 57 configured by extending radial ribs toward the opening of the washing tub 1. During the washing operation, the stirring tub 56 is rotated by the motor 10 without rotating the washing tub 1. As a result, the detergent dissolving blade 57 also rotates.
洗濯槽１の側壁には、洗濯槽の洗剤投入口５８が支持される。洗濯槽の洗剤投入口５８を開放した状態では、洗濯槽の洗剤投入口５８の一方の端部は、洗濯槽１の開口部から外に向かって伸延し、投入した洗剤を、洗濯槽１の外側に流下させる。洗剤は、洗濯槽１の外側の隙間に形成される洗剤流下経路５９を通って流下し、洗剤溶解翼５７に対向する位置まで落下する。
On the side wall of the washing tub 1, a washing tub detergent inlet 58 is supported. In the state in which the detergent input port 58 of the washing tub is opened, one end of the detergent input port 58 of the washing tub extends outward from the opening of the washing tub 1 to transfer the introduced detergent to the washing tub 1 of the washing tub 1. Let it flow down. The detergent flows down through a detergent flow path 59 formed in a gap outside the washing tub 1 and drops to a position facing the detergent dissolving blade 57.
以上のように構成した洗濯機について、その動作、作用を説明する。
The operation and action of the washing machine configured as described above will be described.
図１および図２において、洗剤収容ケース６は、上部筐体３の一部を下方に伸延して構成する洗剤溶解手段８と流路構造部７との間に収容されるので、洗剤水溶液９は、洗剤溶解手段８の流水面８ａを流れ、流路構造部上面７ａを越えることはない。これにより、上部筐体３の洗剤溶解手段８の流水面８ａより高い位置に配置した給水弁１８や操作部１９などの電気部品に洗剤収容ケース６から溢れた水がかかって絶縁不良になることを防止することができる。流路構造部上面７ａと流路構造部下面７ｂとは、略板状の形状に形成しているので、溶着する装置を小型化しやすく、製造しやすく、凹凸が少ないので、溶着品質も安定しやすい。
1 and 2, the detergent accommodating case 6 is accommodated between the detergent dissolving means 8 formed by extending a part of the upper casing 3 downward and the flow path structure portion 7, so that the detergent aqueous solution 9 Flows on the running water surface 8a of the detergent dissolving means 8 and does not exceed the flow path structure upper surface 7a. As a result, the electrical components such as the water supply valve 18 and the operating portion 19 arranged at a position higher than the flowing water surface 8a of the detergent dissolving means 8 of the upper housing 3 are flooded with water from the detergent accommodating case 6 to cause insulation failure. Can be prevented. Since the flow path structure upper surface 7a and the flow path structure lower surface 7b are formed in a substantially plate shape, the welding device is easy to downsize, easy to manufacture, and has no unevenness, so that the welding quality is stable. Cheap.
洗剤溶解手段８は、上部筐体３と一体に構成しているので、水漏れを防止でき、洗剤溶解手段８の流水面８ａを流れる間に洗剤水溶液９の水と洗剤との溶解が促進し、洗浄性能を向上できる。
Since the detergent dissolving means 8 is formed integrally with the upper casing 3, it is possible to prevent water leakage, and promote the dissolution of the detergent aqueous solution 9 in water and the detergent while flowing through the running water surface 8a of the detergent dissolving means 8. The cleaning performance can be improved.
上方より順に、第２の防水壁１７、第１の防水壁１６、第１の排水部１１、第２の排水部１２を配置しているので、第１の排水部１１が第２の排水部１２より高い位置に位置する。このため、洗剤水溶液９は、洗剤溶解手段８の流水面８ａに滞留せず洗濯槽１に流下するので、第１の排水部１１を通過するときの排水が充分でき、第１の排水部１１以外からは、洗剤収容ケース６から水または洗剤水溶液９が溢れないので、水漏れしにくい。第１の防水壁１６は、第１の排水部１１より高い位置に位置する。このため、万一、洗剤収容ケース６から水または洗剤水溶液９が溢れても、第１の排水部１１で排水しやすいので、第１の防水壁１６から水漏れしにくい。さらに、第２の防水壁１７は、第１の防水壁１
６より高い位置に位置する。このため、万一、第１の防水壁１６を超えて水または洗剤水溶液９が溢れても、第２の防水壁１７まで水位が上がりにくいので、第２の防水壁１７からの水漏れを防止でき、上部筐体３に配置した、給水弁１８や、操作部１９、また、モータ１０などの電気部品に水がかかって絶縁不良になることを防止できる。
Since the second waterproof wall 17, the first waterproof wall 16, the first drainage portion 11, and the second drainage portion 12 are arranged in this order from above, the first drainage portion 11 is the second drainage portion. Located higher than 12. Therefore, the detergent aqueous solution 9 does not stay on the running water surface 8a of the detergent dissolving means 8 and flows down into the washing tub 1, so that the drainage when passing through the first drainage portion 11 can be sufficiently performed, and the first drainage portion 11 Except for the above, water or the detergent aqueous solution 9 does not overflow from the detergent containing case 6, so that water does not easily leak. The first waterproof wall 16 is located at a position higher than the first drainage section 11. Therefore, even if water or the detergent aqueous solution 9 overflows from the detergent storage case 6, it is easy to drain the water from the first drainage portion 11, so that the water does not easily leak from the first waterproof wall 16. Further, the second waterproof wall 17 is the first waterproof wall 1
Located higher than 6. Therefore, even if water or detergent solution 9 overflows the first waterproof wall 16, the water level does not easily rise to the second waterproof wall 17, so that water leakage from the second waterproof wall 17 is prevented. Therefore, it is possible to prevent the water supply valve 18, the operation unit 19, and the electric parts such as the motor 10 arranged in the upper housing 3 from being splashed with water to cause insulation failure.
洗濯槽１中心側から見て、順に、衣類投入口４、流路構造部７の摺動面３４（第２の支持手段）、操作部の前縁部３３、開口部３２、洗剤溶解手段の摺動面３０（第１の支持手段）の前縁、第２の排水部１２、洗濯槽開口部内壁１３、洗剤溶解手段８の流水面８ａを配置している。洗剤収容ケース６は、洗剤溶解手段８の摺動面３０（第１の支持手段）だけでなく、流路構造部７の摺動面３４（第２の支持手段）によっても摺動自在に支持される。これにより、洗剤溶解手段８を上部筐体３と一体化するために、洗剤溶解手段８の奥行き寸法を短くしなければならない場合、すなわち、洗剤溶解手段８の摺動面３０（第１の支持手段）が短く開口部３２より外側でしか、洗剤収容ケース６を支持できない場合でも、洗剤収容ケース６を流路構造部７の摺動面３４まで大きく引き出したときに流路構造部７の摺動面３４で支持することができ、洗剤収容ケース６が脱落しないため、使用者が洗剤を確実に投入することができる。
When viewed from the center side of the washing tub 1, the clothes inlet 4, the sliding surface 34 (second supporting means) of the flow path structure 7, the front edge 33 of the operating portion, the opening 32, and the detergent dissolving means are arranged in this order. The front edge of the sliding surface 30 (first supporting means), the second drainage portion 12, the inner wall 13 of the washing tub opening, and the flowing surface 8a of the detergent dissolving means 8 are arranged. The detergent accommodating case 6 is slidably supported not only by the sliding surface 30 (first supporting means) of the detergent dissolving means 8 but also by the sliding surface 34 (second supporting means) of the flow path structure portion 7. To be done. Accordingly, in order to integrate the detergent dissolving means 8 with the upper housing 3, the depth dimension of the detergent dissolving means 8 must be shortened, that is, the sliding surface 30 of the detergent dissolving means 8 (first support). Even when the detergent accommodating case 6 can be supported only outside the opening 32, the sliding of the flow passage structure portion 7 when the detergent storage case 6 is largely pulled out to the sliding surface 34 of the flow passage structure portion 7. Since the detergent can be supported by the moving surface 34 and the detergent containing case 6 does not fall off, the user can reliably put the detergent in.
流路構造部７の摺動面３４（第２の支持手段）は、流路構造部７の一部を構成したことにより、洗剤収容ケース６を、洗剤溶解手段８と流路構造部７のみで、摺動自在に支持することができるので、ツメやねじ等により洗剤溶解手段８と流路構造部７の位置決めをするだけで、洗剤溶解手段８の摺動面３０（第１の支持手段）と、流路構造部７の摺動面３４（第２の支持手段）と、洗剤収容ケース６の摺動面３１の相対位置がずれて、洗剤収容ケース６を引き出しにくくなることを防止することができる。
Since the sliding surface 34 (second support means) of the flow path structure portion 7 constitutes a part of the flow path structure portion 7, the detergent accommodating case 6 is separated from the detergent dissolving means 8 and the flow path structure portion 7. Since it can be slidably supported, the sliding surface 30 of the detergent dissolving means 8 (the first supporting means) can be obtained only by positioning the detergent dissolving means 8 and the flow path structure portion 7 with a claw or a screw. ) And the sliding surface 34 (second supporting means) of the flow path structure portion 7 and the sliding surface 31 of the detergent accommodating case 6 are displaced from each other, thereby preventing the detergent accommodating case 6 from being easily pulled out. be able to.
図１において、洗濯槽１の洗剤投入口５８に洗剤を投入することによって、洗剤を洗剤溶解翼５７まで流下させ、洗濯中に攪拌翼５６を回転させることにより、攪拌翼５６とともに回転する洗剤溶解翼５７によって洗剤を溶解することができる。水道水圧が高いときには、上部筐体３に開閉自在に収容した洗剤収容ケース６に洗剤を投入して水道水の給水時に洗剤を溶解して洗濯槽１に供給し、水道水圧が低いときや、水道を使わずにバケツなどで給水するときには、洗濯槽１の洗剤投入口５８に洗剤を投入して、洗濯運転中の攪拌翼５６の回転により洗剤を溶解できるので、使い勝手がよい。
In FIG. 1, by introducing a detergent into the detergent inlet 58 of the washing tub 1 to cause the detergent to flow down to the detergent dissolving blade 57, and by rotating the stirring blade 56 during washing, the detergent dissolving rotating with the stirring blade 56. The blade 57 allows the detergent to be dissolved. When the tap water pressure is high, when the tap water pressure is low, the detergent is put into the detergent housing case 6 that is openably and closably housed in the upper housing 3, and the detergent is dissolved and supplied to the washing tub 1 when tap water is supplied. When supplying water with a bucket or the like without using water, the detergent can be put into the detergent inlet 58 of the washing tub 1 and dissolved by the rotation of the stirring blades 56 during the washing operation, which is convenient.
図３において、混合室２４と粉砕室２２との間を、仕切壁２３で仕切り、混合室２４へ水を流下する第１流下孔２５と、粉砕室２２へ水を流下する第２流下孔２６とを流路構造部７に連通して設け、粉砕室２２の底部に洗剤水溶液９を下方向に流出するスリット２１から流す構成としている。これにより、洗剤の状況によらず、たとえば、洗剤が湿って塊状になっているような場合でも、洗剤水溶液９中の洗剤は、スリット２１よりも確実に小さくなるまで溶解を促進して、洗濯槽１に供給することができ、洗浄性能を向上することができる。
In FIG. 3, a partition wall 23 is provided between the mixing chamber 24 and the crushing chamber 22 to divide water into the mixing chamber 24, and a first downflow hole 25 and a second downflow hole 26 to flow water into the crushing chamber 22. Are provided so as to communicate with the flow path structure 7, and the detergent solution 9 is made to flow from the slit 21 that flows downward to the bottom of the crushing chamber 22. As a result, regardless of the state of the detergent, for example, even when the detergent is wet and clumped, the detergent in the detergent aqueous solution 9 promotes dissolution until it becomes smaller than the slit 21 and is washed. It can be supplied to the tank 1, and the cleaning performance can be improved.
水道水圧が低く、流路構造部７の水圧が低く、第１流下孔２５と第１流下孔２５に連通する第２流下孔２６から出る水の流速が低いときには、混合室２４の水位もゆっくり上昇し、混合室２４内の洗剤が一度に仕切壁２３を超えることなく、第１流下孔２５からの水によって、充分な時間をかけて溶解した後に粉砕室２２に送られる。このため、水道水圧が低くい場合でも、溶解を促進して、洗濯槽１に供給することができ、洗浄性能を向上することができる。
When the tap water pressure is low, the water pressure in the flow path structure portion 7 is low, and the flow velocity of water exiting from the first downflow hole 25 and the second downflow hole 26 communicating with the first downflow hole 25 is low, the water level in the mixing chamber 24 is also slow. The detergent in the mixing chamber 24 ascends and does not exceed the partition wall 23 at a time, and is dissolved in the water from the first downflow hole 25 for a sufficient time and then sent to the crushing chamber 22. Therefore, even when the tap water pressure is low, the dissolution can be promoted and the water can be supplied to the washing tub 1, and the cleaning performance can be improved.
水道水圧が高く、流路構造部７の水圧が高く、第１流下孔２５と第１流下孔２５に連通する第２流下孔２６から出る水の流速が早いときは、混合室２４の水位が早く上昇し、混合室２４内の洗剤が仕切壁２３を短時間で超える。この場合でも、仕切壁２３を超えるま
での間は、水と洗剤とが混合される時間を有することができる。第２流下孔２６からの水の流速も高いので、粉砕室２２で洗剤が勢いよく粉砕され、短時間で洗剤溶解することができる。このため、水道水圧が高くても、溶解を促進して、洗濯槽１に供給することができ、洗浄性能を向上することができる。
When the tap water pressure is high, the water pressure in the flow path structure portion 7 is high, and the flow velocity of water exiting from the first downflow hole 25 and the second downflow hole 26 communicating with the first downflow hole 25 is high, the water level in the mixing chamber 24 is It rises quickly and the detergent in the mixing chamber 24 exceeds the partition wall 23 in a short time. Even in this case, the water and the detergent can be mixed until the partition wall 23 is exceeded. Since the flow velocity of water from the second downflow hole 26 is also high, the detergent is vigorously pulverized in the pulverization chamber 22, and the detergent can be dissolved in a short time. Therefore, even if the tap water pressure is high, dissolution can be promoted and the water can be supplied to the washing tub 1, and the cleaning performance can be improved.
洗剤溶解手段８の流水面８ａに、スリット２１に向けてピン２０を立設し、ピン２０の先端は、スリット２１に挿入している。これにより、スリット２１を通るまでに細かく粉砕された洗剤は、洗剤溶解手段８の流水面８ａ上で、ピン２０の間を通る間にさらに細かく粉砕されるので、効率よく洗剤を溶解できる。スリット２１の長手方向は、洗剤収容ケース６の摺動方向と略同一にしているので、使用者が、洗濯機に洗剤を入れる度に洗剤収容ケース６を出し入れすることにより、スリット２１に固着した洗剤を、摺動するピン２０によって剥離することができ、スリット２１に洗剤が固着して、目詰まりすることを防止できるので、効率よい洗剤溶解を、長期にわたって実現できる。
A pin 20 is erected on the running water surface 8a of the detergent dissolving means 8 toward the slit 21, and the tip of the pin 20 is inserted into the slit 21. As a result, the detergent finely crushed by the time it passes through the slit 21 is further finely pulverized while passing between the pins 20 on the flowing water surface 8a of the detergent dissolving means 8, so that the detergent can be efficiently dissolved. Since the longitudinal direction of the slit 21 is substantially the same as the sliding direction of the detergent accommodating case 6, the user fixed the slit 21 by taking the detergent accommodating case 6 in and out each time the detergent is inserted into the washing machine. Since the detergent can be peeled off by the sliding pin 20 and the detergent can be prevented from sticking to the slits 21 and clogging, efficient detergent dissolution can be realized for a long period of time.
洗剤水溶液速度調整壁２７は、粉砕室２２領域の上方に備えている。これにより、水道水圧が高く流路構造部７の第１流下孔２５から流下する流量が大きい場合でも、仕切壁２３を勢いよく超えた洗剤水溶液９の流れを、洗剤水溶液速度調整壁２７によって粉砕室２２の方向に、図３では下向きに変えて流すことができる。よって、洗剤水溶液９が粉砕室２２の範囲にとどまりやすく、洗剤溶解が進む前に粉砕室２２を越えて洗剤水溶液９が流下するのを抑制できるので、洗剤を効率よく溶かすことができ、洗浄性能を向上することができる。
The detergent aqueous solution speed adjusting wall 27 is provided above the region of the crushing chamber 22. As a result, even if the tap water pressure is high and the flow rate flowing down from the first downflow hole 25 of the flow path structure portion 7 is large, the flow of the detergent aqueous solution 9 that vigorously exceeds the partition wall 23 is crushed by the detergent aqueous solution speed adjusting wall 27. The flow can be changed in the direction of the chamber 22 and downward in FIG. Therefore, the aqueous detergent solution 9 easily stays within the range of the crushing chamber 22, and it is possible to prevent the detergent aqueous solution 9 from flowing down over the crushing chamber 22 before the detergent dissolution proceeds, so that the detergent can be efficiently dissolved and the cleaning performance can be improved. Can be improved.
図５において、水跳ね抑制壁２８ａは、洗剤溶解手段８の流水面８ａの第１流下孔２５に対向する位置近傍に、流水方向に伸延させて形成している。これにより、洗剤収容ケース６を取り付け忘れて運転した場合に、第１流下孔２５から流下して、洗剤溶解手段８の流水面８ａ上で四方に水が跳ねるが、一部は水跳ね抑制壁２８ａに当たり、上方向に流れがかわる。このため、洗剤溶解手段８の流水面８ａの第２の排水部１２側開口から機器前方に跳ねるのを抑制することができる。
In FIG. 5, the water splash suppressing wall 28a is formed by extending in the flowing direction in the vicinity of the position on the flowing surface 8a of the detergent dissolving means 8 facing the first downflow hole 25. Accordingly, when the detergent storage case 6 is forgotten to be mounted and the vehicle is driven, the water flows down from the first downflow hole 25 and splashes in four directions on the flowing water surface 8a of the detergent dissolving means 8, but a part of the water splash suppressing wall. When hitting 28a, the flow changes upward. For this reason, it is possible to suppress the splashing toward the front of the device from the opening on the second drainage section 12 side of the flowing water surface 8a of the detergent dissolving means 8.
水跳ね抑制壁２８ａの第２の排水部１２側の一端は、流水方向と異なる方向に略Ｊ字に伸延しているので、第１流下孔２５から流下して、水が洗剤溶解手段の流水面８ａ上で四方に跳ねる場合には、水が排水部１２側から跳ねることを抑制することができる。水跳ね抑制壁２８ｂ、２８ｃは、流水方向と異なる方向に略Ｃ字に、第２流下孔２６に対向する位置を囲うように伸延している。これにより、第２流下孔２６からの水が洗剤溶解手段の流水面８ａ上で四方に跳ねる場合には、一部は水跳ね抑制壁２８ｂ、２８ｃに当たり、上方向に流れがかわる。このため、機器前方に跳ねることを抑制できるので、洗剤収容ケース６をとりはずした状態でも、機器前方の使用者をぬらすことがない。
Since one end of the water splash prevention wall 28a on the second drainage section 12 side extends in a substantially J-shape in a direction different from the flowing direction, the water flows down from the first downflow hole 25, and the water flows into the detergent dissolving means. When splashing in all directions on the surface 8a, it is possible to prevent water from splashing from the drain portion 12 side. The water splash suppressing walls 28b and 28c extend in a substantially C shape in a direction different from the flowing water direction so as to surround a position facing the second downflow hole 26. Thereby, when the water from the second downflow hole 26 splashes in all directions on the running water surface 8a of the detergent dissolving means, a part of the water hits the water splash suppressing walls 28b and 28c and the flow is changed upward. For this reason, it is possible to prevent the user from bouncing toward the front of the device, so that the user in front of the device will not get wet even when the detergent storage case 6 is removed.
水跳ね抑制壁２８ｂ、２８ｃの洗剤水溶液９の流水する方向は、開口しているので、洗剤水溶液９が残水することがない。第２の排水部１２側の一端で略Ｊ字に曲げている水跳ね抑制壁２８ａ近傍の洗剤溶解手段８の流水面８ａには、洗濯槽１に向けて連通する排水孔２９を、洗濯槽１の洗濯槽開口部内壁１３より内側の範囲に開口している。これによって、洗剤溶解手段の流水面８ａを流れる水の一部を、洗濯槽１以外の場所に溢れさせることなく、洗濯槽１にむけて排水でき、また、水跳ね抑制壁２８ａでせき止められ、あるいは、流れの方向を抑制された洗剤水溶液９が、洗剤溶解手段８の流水面８ａにとどまり、その後乾燥して洗剤だけが洗剤溶解手段８の流水面８ａに固着するのを防止することができる。
Since the water splash suppressing walls 28b and 28c are opened in the flowing direction of the detergent aqueous solution 9, the detergent aqueous solution 9 does not remain. A drainage hole 29 communicating with the washing tub 1 is provided in the running water surface 8a of the detergent dissolving means 8 near the water splash suppressing wall 28a which is bent in a substantially J shape at one end on the second draining section 12 side. The inner wall 13 of the washing tub opening 1 is open to the inside. Thereby, a part of the water flowing on the running water surface 8a of the detergent dissolving means can be drained toward the washing tub 1 without overflowing to a place other than the washing tub 1, and can be dammed by the water splash suppressing wall 28a. Alternatively, it is possible to prevent the detergent aqueous solution 9 whose flow direction is suppressed from remaining on the running water surface 8a of the detergent dissolving means 8 and then drying to adhere only the detergent to the running water surface 8a of the detergent dissolving means 8. ..
洗剤溶解手段８の流水面８ａは、上部筐体３の一部下方に伸延して構成し、その周囲を洗剤溶解手段８の周囲壁８ｂで囲い、その上部を流路構造部７で覆って、さらに流路構造
部７一体に構成した第２の防水壁１７で防水している。これにより、洗剤溶解手段８と、水跳ね抑制壁２８ａ、２８ｂ、２８ｃは、金型により成型時に、図５の上下方向、すなわち、上部筐体３の成型金型の開き方向と同一方向に金型を移動することによって成型できるので、スライド金型などを使わなくても、簡単に成型できる。
The running water surface 8a of the detergent dissolving means 8 is formed by extending a part of the upper casing 3 downward, the periphery thereof is surrounded by a peripheral wall 8b of the detergent dissolving means 8, and the upper portion thereof is covered with the flow path structure portion 7. Further, it is waterproofed by a second waterproof wall 17 which is formed integrally with the flow path structure section 7. As a result, the detergent dissolving means 8 and the water splash suppressing walls 28a, 28b, 28c are molded in the mold in the vertical direction of FIG. 5, that is, in the same direction as the opening direction of the mold of the upper housing 3. Since it can be molded by moving the mold, it can be molded easily without using a slide mold.
さらに、図４において、排水孔２９は、第１流下孔２５の一つと対向する位置に開口しているので、第１流下孔２５から流下した水は、洗剤溶解手段８の流水面８ａにあたることがなく、直接洗濯槽１に流下させることができるため、洗剤収容ケース６を装着していなくても、水が洗剤溶解手段８の流水面８ａで機器前方に跳ねることを抑制できる。
Further, in FIG. 4, since the drain hole 29 is opened at a position facing one of the first downflow holes 25, the water flowing down from the first downflow hole 25 must hit the running water surface 8 a of the detergent dissolving means 8. Since the water can be made to flow down directly into the washing tub 1, it is possible to prevent water from splashing in front of the equipment at the flowing water surface 8a of the detergent dissolving means 8 even if the detergent accommodating case 6 is not attached.
図６において、洗剤収容ケース６を引き出すときに、洗剤収容ケース６のツメ３７と、流路構造部７のツメ３５とで位置規制している。これにより、毎回、所定の引き出し量で第１収容室１４、第２収容室１５に洗剤、柔軟剤を入れることができ、使い勝手がよい。さらに、使用者が、洗剤収容ケース６のはり部３６を押し下げるだけで洗剤収容ケース６を取り外すことができるので、使い勝手がよい。洗剤収容ケース６のツメ３７と、流路構造部のツメ３５の係り代を大きくしても、洗剤収容ケース６のはり部３６を押し下げるだけで外せるので、使い勝手をよくできる。
In FIG. 6, when the detergent containing case 6 is pulled out, the position thereof is regulated by the claw 37 of the detergent containing case 6 and the claw 35 of the flow path structure portion 7. As a result, the detergent and the softening agent can be put into the first storage chamber 14 and the second storage chamber 15 each time with a predetermined withdrawal amount, which is convenient. Further, the user can remove the detergent accommodating case 6 simply by pushing down the beam portion 36 of the detergent accommodating case 6, which is convenient. Even if the tab 37 of the detergent accommodating case 6 and the tab 35 of the flow path structure section are made larger, they can be removed by simply pushing down the beam section 36 of the detergent accommodating case 6, so that the usability can be improved.
洗剤収容ケース６のツメ３７と、流路構造部のツメ３５は、洗剤収容ケース６の略中央一箇所にあるため、洗剤収容ケース６が左右にがたつきにくい上、洗剤収容ケース６のはり部３６を押し下げる操作は片手で行なうことができ、簡単に取り外せるので使い勝手がよい。洗剤収容ケース６を引き出した状態で、洗剤収容ケース６のはり部３６を視認できるので、洗剤収容ケース６の取り外し方法を、視覚的に容易に判断でき、使い勝手がよくなる。
Since the claw 37 of the detergent containing case 6 and the claw 35 of the flow path structure portion are located at substantially one center of the detergent containing case 6, the detergent containing case 6 is less likely to rattle to the left and right, and the beam of the detergent containing case 6 does not easily rattle. The operation of pushing down the portion 36 can be performed with one hand and can be easily removed, which is convenient. Since the beam portion 36 of the detergent accommodating case 6 can be visually recognized with the detergent accommodating case 6 pulled out, the method for removing the detergent accommodating case 6 can be easily visually determined and the usability is improved.
洗剤収容ケース６を取り付ける際には、洗剤収容ケース６のはり部３６が弾性的に下方にたわんで、乗り越えることで、洗剤収容ケース６のツメ３７と流路構造部７のツメ３５とが係止する。使用者は、洗剤収容ケース６を押し込むだけで所定の位置に装着できるので、洗剤収容ケース６の摺動方向以外に力を入れる必要がなく、使い勝手がよい。
When the detergent accommodating case 6 is attached, the beam portion 36 of the detergent accommodating case 6 elastically bends downward and gets over, so that the claw 37 of the detergent accommodating case 6 and the claw 35 of the flow path structure part 7 are engaged. Stop. Since the user can mount the detergent accommodating case 6 at a predetermined position just by pushing the detergent accommodating case 6, it is not necessary to apply a force in a direction other than the sliding direction of the detergent accommodating case 6, which is convenient.
洗剤収容ケース６の略中央には、洗剤収容ケース６のツメ３７(第１の係止手段)と、流路構造部７のツメ３５(第２の係止手段)とを有しており、ツメ３７及びツメ３５から離れた位置、すなわち、洗剤収容ケース６の左右端に、流路構造部７の支持手段３８と洗剤収容ケース６の位置抑制手段３９とを近接して有している。これにより、衣類投入口４を大きくするために、洗剤収容ケース６のツメ３７から洗剤収容ケース６の後方端面までの距離が短くなった場合でも、洗剤を投入しやすいように洗剤収容ケース６を開いた際に、流路構造部７の支持手段３８と洗剤収容ケース６の位置抑制手段３９とが近接しているため、洗剤収容ケース６のがたつきが少なく、洗剤を投入しやすい。
The detergent accommodating case 6 has a claw 37 (first engaging means) of the detergent accommodating case 6 and a claw 35 (second engaging means) of the flow path structure portion 7 substantially at the center thereof. The support means 38 of the flow path structure 7 and the position restraining means 39 of the detergent containing case 6 are provided close to each other at a position apart from the claws 37 and 35, that is, at the left and right ends of the detergent containing case 6. As a result, even if the distance from the claw 37 of the detergent storage case 6 to the rear end surface of the detergent storage case 6 becomes short in order to make the clothes insertion port 4 large, the detergent storage case 6 can be easily inserted into the detergent storage case 6. When opened, the support means 38 of the flow path structure portion 7 and the position restraining means 39 of the detergent accommodating case 6 are close to each other, so that the detergent accommodating case 6 has less rattling and the detergent can be easily dispensed.
流路構造部７の支持手段３８は、流路構造部下面７ｂの前後方向、すなわち、洗剤収容ケース６の摺動方向に流路構造部下面７ｂの全長分の長さにわたって同一断面を有したレール形状に形成して、洗剤収容ケース６の第１収容室１４と第２収容室１５の左右端部に当接させている。これにより、投入する洗剤の量を多くするために、洗剤収容ケース６を横長に設計する場合でも、洗剤収容ケース６を前後に摺動する際、洗剤収容ケース６左右端部の動きが抑制されるので、洗剤収容ケース６のがたつきが少なく、洗剤を投入しやすくできる。
The supporting means 38 of the flow channel structure 7 has the same cross section in the front-back direction of the flow channel structure lower surface 7b, that is, in the sliding direction of the detergent accommodating case 6 over the entire length of the flow channel structure lower surface 7b. It is formed in a rail shape and is brought into contact with the left and right ends of the first storage chamber 14 and the second storage chamber 15 of the detergent storage case 6. As a result, even when the detergent containing case 6 is designed to be horizontally long in order to increase the amount of detergent to be added, movement of the left and right end portions of the detergent containing case 6 is suppressed when the detergent containing case 6 is slid back and forth. Therefore, the detergent containing case 6 has less rattling, and the detergent can be easily introduced.
流路構造部下面７ｂ、流路構造部７の摺動面３４、流路構造部７のツメ３５、および流路構造部７の支持手段３８は、一体に構成しているので、流路構造部７のツメ３５と、流路構造部７の支持手段３８とは、一つの部品で構成でき、位置ずれしにくくなり、洗剤収
容ケース６のがたつきを少なくするために、流路構造部７の支持手段３８と洗剤収容ケース６の位置抑制手段３９との隙間を小さく設計しても、洗剤収容ケース６の摺動が妨げられることを防止できる。
Since the lower surface 7b of the flow channel structure portion, the sliding surface 34 of the flow channel structure portion 7, the claws 35 of the flow channel structure portion 7, and the supporting means 38 of the flow channel structure portion 7 are integrally configured, the flow channel structure portion is formed. The claws 35 of the portion 7 and the supporting means 38 of the flow channel structure portion 7 can be configured by one component, are less likely to be displaced, and reduce the rattling of the detergent accommodating case 6. Even if the gap between the supporting means 38 of No. 7 and the position suppressing means 39 of the detergent containing case 6 is designed to be small, it is possible to prevent the sliding of the detergent containing case 6 from being hindered.
図７、図８、図９、図１０において、第１の給水手段４８は、洗濯槽１の中心から左側に偏心した位置に給水し、第２の給水手段４９は、第１の給水手段４８とは略対称の右側に偏心した位置に給水するので、水道水圧が低くてシャワー水５０を扇形に広げられない場合でも、洗濯物５５全体に均一にシャワー水５０をしみこませることができ、洗濯性能を向上することができる。第１の給水手段４８と、第２の給水手段４９とは、横方向流路４１の左右端に配置し、給水弁１８、流路構造部７を共有化できるので、洗濯機本体をコンパクトに設計することができる。
7, FIG. 8, FIG. 9, and FIG. 10, the first water supply means 48 supplies water to a position eccentric to the left side from the center of the washing tub 1, and the second water supply means 49 supplies the first water supply means 48. Since the water is supplied to a position eccentric to the right side, which is substantially symmetrical to, the shower water 50 can be uniformly impregnated into the entire laundry 55 even when the tap water pressure is low and the shower water 50 cannot be fanned out. The performance can be improved. The first water supply means 48 and the second water supply means 49 are arranged at the left and right ends of the lateral flow passage 41, and the water supply valve 18 and the flow passage structure portion 7 can be shared, so that the washing machine main body can be made compact. Can be designed.
洗濯槽１が時計方向に回転する第１の回転状態では、洗濯槽１の左側に位置する洗濯物５５は、洗濯槽１の左側に位置する第１の給水手段４８に向かって近づく方向に動き、第１の水平開口部４６（第１の付勢手段）により、シャワー水５０は、洗濯槽１に向かって、すなわち、洗濯物５５の移動方向の略反対方向に付勢される。図９のように、第１の給水手段４８からのシャワー水５０は、洗濯物５５の移動に合わせて、右下から順に上方向に移動しながら洗濯物５５にかけられる。
In the first rotation state in which the laundry tub 1 rotates clockwise, the laundry 55 located on the left side of the laundry tub 1 moves toward the first water supply means 48 located on the left side of the laundry tub 1. The shower water 50 is urged toward the washing tub 1 by the first horizontal opening 46 (first urging means), that is, in a direction substantially opposite to the moving direction of the laundry 55. As shown in FIG. 9, the shower water 50 from the first water supply means 48 is applied to the laundry 55 while moving upward in order from the lower right in accordance with the movement of the laundry 55.
洗濯槽１が反時計方向に回転する第２の回転状態では、図１０のように、第２の給水手段４９によって、洗濯物５５の反対側、左下から順に上方向に移動しながら、シャワー水５０が洗濯物５５にかけられる。これにより、第１の回転状態、第２の回転状態を繰り返す間に、洗濯物５５全体に均一にシャワー水５０をしみこませることができ、洗濯性能を向上することができる。
In the second rotation state in which the washing tub 1 rotates counterclockwise, as shown in FIG. 10, the shower water is moved upward by the second water supply means 49 in the order from the lower left side to the opposite side of the laundry 55. 50 is hung on the laundry 55. As a result, while the first rotation state and the second rotation state are repeated, the shower water 50 can be uniformly impregnated into the entire laundry 55, and the washing performance can be improved.
特に、脱水運転の後、すすぎ運転をする際には、洗濯槽１が高速回転することによって遠心力により、洗濯槽１の周囲に洗濯物５５が張り付いた状態になるので、第１の水平開口部４６と第２の水平開口部４７を洗濯槽１の周囲方向に向けることにより、洗濯物５５全体に均一にシャワー水５０をしみこませることができ、洗濯性能を向上することができる。
In particular, when the washing operation is performed after the dehydration operation, the laundry 55 is attached to the periphery of the washing tub 1 due to the centrifugal force due to the high-speed rotation of the washing tub 1, so that the first horizontal By orienting the opening 46 and the second horizontal opening 47 in the circumferential direction of the washing tub 1, the shower water 50 can be uniformly soaked in the entire laundry 55, and the washing performance can be improved.
図２に示すように、第１の給水手段４８と第２の給水手段４９とは、洗剤収容ケース６の左右に隣接して配置され、流路構造部７、給水弁１８を共有化できるので、洗濯機本体をコンパクトに設計できるうえ、洗剤水溶液９とシャワー水とを同時に洗濯槽１に投入することにより、洗濯時間を短縮することができる。なお、給水手段は、２つ備えることで説明したが、２つに限定するものではなく、２つ以上給水手段を備えても、同様の効果がある。
As shown in FIG. 2, the first water supply means 48 and the second water supply means 49 are arranged adjacent to each other on the left and right of the detergent accommodating case 6, and the flow path structure portion 7 and the water supply valve 18 can be shared. The main body of the washing machine can be designed compact, and the washing time can be shortened by pouring the detergent solution 9 and the shower water into the washing tub 1 at the same time. Although it has been described that two water supply means are provided, the number of water supply means is not limited to two, and the same effect can be obtained even if two or more water supply means are provided.
図１１において、端部開口部５１は、略円形に開口していて、第１の水平開口部４６および第２の水平開口部４７の縦方向開口寸法より大きい開口寸法を有しているので、水流が太くなり、表面張力などの影響を受けにくい水流を両端から放射状に噴出でき、端部開口部５１の間に第１の水平開口部４６と第２の水平開口部４７からの水を膜状に広げることができるので、水道水圧が低いときでも、シャワー水５０を扇形に広げやすい。
In FIG. 11, the end opening 51 has a substantially circular opening and has an opening size larger than the vertical opening size of the first horizontal opening 46 and the second horizontal opening 47. The water flow becomes thick, and the water flow that is not easily affected by surface tension can be ejected radially from both ends, and the water from the first horizontal opening 46 and the second horizontal opening 47 is formed between the end openings 51. The shower water 50 can be easily fan-shaped even when the tap water pressure is low.
第１の水平開口部４６と、第１の水平開口部４６の左右の端部開口部５１とを加えた開口面積Ｓ１は、第１の水管部４３の流路断面積Ｓ２よりも小さく設定しているいので、水道水圧が低くても、第１の水平開口部４６には、水位に応じた一定の水圧がかかり続けるので、シャワー水５０を安定して噴出し続けることができ、シャワー水５０を扇形に広げやすくできる。
An opening area S1 obtained by adding the first horizontal opening 46 and the left and right end openings 51 of the first horizontal opening 46 is set to be smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43. Therefore, even if the tap water pressure is low, a constant water pressure according to the water level continues to be applied to the first horizontal opening portion 46, so that the shower water 50 can be continuously jetted out stably. Can be easily fanned out.
顎部５２の内側は、絞り面５３により、球面部４５の一部を第１の水平開口部４６の縁まで伸延して形成しているので、水圧は、球面部４５の面に垂直にかかり、水平開口部４６からシャワー水５０をまっすぐ噴出しやくなり、シャワー水５０を扇形に広げやすい。顎部５２の外側は、第１の水平開口部４６の縁から第１の水管部４３の伸延方向に対して下方に後退する後退面５４を有しているので、金型抜き方向のみで第１の水平開口部４６を成型でき、金型にスライド機構を追加せずに成型できるので、容易に製造することができる。
The inner side of the jaw portion 52 is formed by extending the part of the spherical surface portion 45 to the edge of the first horizontal opening portion 46 by the diaphragm surface 53, so that the water pressure is applied perpendicularly to the surface of the spherical surface portion 45. The shower water 50 is easily jetted straight from the horizontal opening 46, and the shower water 50 is easily fan-shaped. The outside of the jaw portion 52 has a receding surface 54 that recedes downward from the edge of the first horizontal opening portion 46 with respect to the extending direction of the first water pipe portion 43. Since one horizontal opening 46 can be molded and molding can be performed without adding a slide mechanism to the mold, it can be easily manufactured.
