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, a 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 accommodates the washing tub 101 in a rotatable manner, and an upper casing 103 that covers substantially the entire upper part of the washing machine main body 102 is mounted on the upper part of the washing machine main body 102. A clothing input port 104 formed integrally with the upper housing 103 and extending downward toward the upper side of the washing tub 101 is formed at substantially the center of the upper housing 103. A lid 105 that covers the entire upper portion of the clothing insertion port 104 is attached to the upper housing 103 so as to be freely opened and closed. 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。
In the upper housing 103, a detergent storage case 106 for storing detergent is disposed in the vicinity of the clothing insertion port 104 so as to be freely 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 and flows down to each part of the detergent storage case 106. The flow path structure portion 107 constitutes the upper surface of the flow path structure portion 107, constitutes the upper surface 107a of the flow path structure portion that prevents water leakage from the flow path structure portion 107, and the lower surface of the flow path structure portion 107. It consists of a channel structure lower surface 107b through which water supplied to the housing case 106 flows down. A detergent dissolving means 108 is configured below the detergent storage case 106. The detergent storage case 106 mixes the tap water and the detergent to produce a detergent aqueous 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 channel structure upper surface 107 a and the detergent dissolving means 108 are configured integrally, open to the washing tub 101 side, and configured to 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 channel structure 107 is large, the detergent aqueous solution 109 overflowing from the detergent storage case 106 and the detergent dissolving means 108 is left in the washing machine main body 102 and the upper casing 103. Since it is prevented from overflowing, it is prevented that water splashes on the electric parts such as the motor 110 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 storage case 106 is formed with a first drainage portion 111 at one end located on the opposite side of the clothes insertion port 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。
In the detergent dissolving means 108, a second drainage portion 112 is formed at one end located on the clothing input port 104 side. The detergent aqueous solution 109 flowing down on the surface of the detergent dissolving means 108 is drained from the second drainage part 112 to the clothing input port 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 part 111 toward the second drainage part 112. The second drainage portion 112 is disposed outside the clothing input port 104 and inside the washing tub opening inner wall 113 at the opening end of the washing tub 101 on the clothing input 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 inner wall 113 of the washing tub opening, so that the detergent aqueous solution 109 travels between the washing tub 101 and the washing machine main body 102 to generate the motor 110. This prevents water from splashing on electrical components such as those 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 a claw, a screw or the like (not shown) after assembling electric parts such as a lead wire and a sensor (not shown) in addition to the detergent dissolving means 108 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 dissolution means 108, and the like are assembled in the upper housing 103 in a unit state, and therefore can be easily manufactured.
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 is provided with 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 storage 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. Moreover, since the rib 120 slides in the slit 121 every time the user inserts and removes the detergent storage case 106, it is possible to prevent the detergent from adhering between the rib 120 and the slit 121 and clogging. The detergent dissolving means 108 is inclined downward from the first drainage portion 111 toward the second drainage portion 112, and the rib 120 extends from the bottomed side of the detergent dissolving means 108 toward the open side. Therefore, when the detergent dissolving means 108 is prepared, the mold drawing direction and the rib 120 extending direction can be made the same and 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 container is slidably supported on the sliding surface 130 of the detergent dissolving means. The claws 135a and 135b of the flow path structure portion disposed on the left and right of the flow path structure portion 107 are disposed so as to contact the edge portion 134 of the detergent storage case when the detergent storage case 106 is pulled out most.
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。
Thus, when the detergent is put into the detergent storage case 106, the position of the detergent storage case 106 is regulated by bringing the claws 135a and 135b of the flow path structure 107 into contact with the edge 134 of the detergent storage case 106. This eliminates rattling and makes it easier to add detergent. When cleaning the detergent storage case 106, the detergent storage case 106 is pulled out and then lifted obliquely upward to remove the edge 134 of the detergent storage case 106 from the claws 135a and 135b of the flow path structure 107, and the detergent storage case 106 can be removed.
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. A claw 135 of the flow path structure portion 107 is provided in the center of the flow path structure portion 107, on the surface facing the detergent storage case 106, and comes into contact with the claw 137 of the detergent storage case when the detergent storage case 106 is pulled out most. . The detergent storage 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。
As a result, the left and right wall surfaces of the rear part of the detergent storage case 106 are regulated by the inner wall of the detergent dissolution means 108 to eliminate rattling when the detergent storage case 106 is pulled to a position where it touches the claw 137. , Make it easy to put detergent. When removing the detergent storage case 106, the beam 36 of the detergent storage case 106 that elastically holds the claw 137 of the detergent storage case 106 is pushed down, and the claw 137 of the detergent storage case 106 is removed from the claw 135 of the flow path structure 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, a water supply means 151 for applying shower water 150 a and 150 b to clothing is provided above the washing tub 101. Water in the washing tub 101 is pumped up by a pump (not shown), pressurized and sent to the water supply means 151. The water supply means 151 further includes a circular first discharge port 152 provided on the bottom surface, and a second discharge port 153 that is opened in a substantially horizontal direction on the outer peripheral surface. A throttle 154 is provided in front of the first discharge port 152 and the second discharge port 153, and the flow rate is increased by the throttle 154.
これにより、第１の吐出口１５２から噴出し、下方向に広がるシャワー水１５０ａと、第２の吐出口１５３から噴出し水平方向に広がるシャワー水１５０ｂとによって、洗濯槽１０１内の洗濯物１５５に均一にシャワー水１５０ａ、１５０ｂをかけて、効率よく洗浄できるようにしている。
As a result, the shower water 150a that is ejected from the first discharge port 152 and spreads downward, and the shower water 150b that is ejected from the second discharge port 153 and spreads horizontally is applied to the laundry 155 in the laundry tub 101. The shower water 150a, 150b is uniformly applied so that the cleaning can be performed efficiently.

The first water pipe part 43 and the first horizontal opening part 46 constitute a first water supply means 48, and the second water pipe part 44 and the second horizontal opening part 47 constitute a second water supply means 49. It is composed.
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 from the first horizontal opening 46 and the second horizontal opening 47 toward the laundry tub 1 to the laundry 55 in the laundry 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 first horizontal opening 46 and the second horizontal opening 47 open obliquely downward toward the washing tub 1 side in the spherical portion 45 centering on the central axis of the water tube portion 43 and the water tube portion 44. Water flows perpendicularly to the first horizontal opening 46 and the second horizontal opening 47 around the central axis 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 constitute urging means for determining the water ejection direction, respectively.
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 rotated clockwise by the motor 10 and a second rotation state rotated counterclockwise, and the water supply valve 18 is opened during washing and rinsing. The shower water 50 is supplied to the laundry 55 in the washing tub 1 during these rotations.
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。
Thereby, in the 1st rotation state, the laundry 55 in the left side of the washing tub 1 moves in the direction approaching toward the 1st water supply means 48 in the left side of the washing tub 1 similarly. Similarly, in the second rotation state, the laundry 55 on the right side of the laundry tub 1 moves in a direction approaching the second water supply means 49 on the right side of the laundry tub 1.
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. Thereby, it forms in the opening shape similar to the rubber hose front-end | tip opening shape at the time of pinching the front-end | tip of a rubber hose with a finger and spreading water in a fan shape and discharging water.
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 channel cross-sectional area S2 of the first water pipe unit 43, and the opening area of the channel restricting unit 42 It is set larger. The channel cross-sectional area S <b> 2 of the first water pipe portion 43 is set to be substantially the same as the channel cross-sectional area of the lateral channel 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 path 41, the first water pipe section 43, and the first horizontal opening 46 via the flow path narrowing section 42 has no throttled portion, that is, the flow path cross section There is no narrowing, and the water pressure in the flow path can be made difficult to decrease. When the tap water pressure is low and the flow rate is small, the speed of the shower water 50 from the first horizontal opening 46 is also reduced, and the reduction of the water in the first water pipe portion 43 is also delayed.
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 smaller than the flow passage cross-sectional area S2 of the first water pipe portion 43, the shower water 50 From this speed, 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 is stabilized, and the first horizontal opening 46 has a water level. Continue to apply a certain water pressure. 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 constituting the lower half. The inside of the jaw 52 has a throttle surface 53 that extends a part of the spherical portion 45 to the edge of the first horizontal opening 46 and restricts the cross-sectional area of the flowing water path. The outside of the jaw 52 has a receding surface 54 that recedes downward from the edge of the first horizontal opening 46 with respect to the extending direction of the first water pipe 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 that applies washing force to the laundry for washing. Below the stirring blade 56, there is provided a detergent dissolving blade 57 formed by extending radial ribs toward the opening of the washing tub 1. During the washing operation, the washing tub 1 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 detergent charging port 58 of the washing tub is supported. In a state where the detergent charging port 58 of the washing tub is opened, one end of the detergent charging port 58 of the washing tub extends outward from the opening of the washing tub 1, Allow to flow outward. The detergent flows down through a detergent flow path 59 formed in a gap outside the washing tub 1 and falls 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。
About the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated.
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。
In FIG. 1 and FIG. 2, the detergent storage case 6 is stored between the detergent dissolution means 8 configured by extending a part of the upper housing 3 downward and the flow path structure portion 7. Flows on the flowing water surface 8a of the detergent dissolving means 8 and does not exceed the upper surface 7a of the flow path structure portion. As a result, the water overflowing from the detergent storage case 6 is applied to the electrical components such as the water supply valve 18 and the operation unit 19 disposed at a position higher than the water flow surface 8a of the detergent dissolving means 8 of the upper housing 3, resulting in poor insulation. Can be prevented. Since the flow channel structure upper surface 7a and the flow channel structure lower surface 7b are formed in a substantially plate shape, the welding apparatus is easy to miniaturize, easy to manufacture, and has few irregularities, 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 constructed integrally with the upper housing 3, water leakage can be prevented, and dissolution of the detergent aqueous solution 9 with water and the detergent is promoted while flowing through the water surface 8 a of the detergent dissolving means 8. , Can improve the cleaning performance.
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 2nd waterproof wall 17, the 1st waterproof wall 16, the 1st drainage part 11, and the 2nd drainage part 12 are arranged in order from the upper part, the 1st drainage part 11 is the 2nd drainage part. It is located at a position higher than 12. For this reason, since the detergent aqueous solution 9 does not stay on the flowing water surface 8a of the detergent dissolving means 8 and flows down to the washing tub 1, drainage when passing through the first drainage part 11 can be sufficiently performed, and the first drainage part 11 Since water or the detergent aqueous solution 9 does not overflow from the detergent housing case 6 from other than the above, it is difficult for water to leak. The first waterproof wall 16 is positioned higher than the first drainage unit 11. For this reason, 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 unit 11, and thus it is difficult for water to leak from the first waterproof wall 16. Furthermore, the second waterproof wall 17 is the first waterproof wall 1.
It is located at a position higher than 6. For this reason, even if water or detergent aqueous solution 9 overflows beyond the first waterproof wall 16, the water level is unlikely to rise to the second waterproof wall 17, thus preventing water leakage from the second waterproof wall 17. In addition, it is possible to prevent the water supply valve 18, the operation unit 19, and the electric parts such as the motor 10 disposed in the upper housing 3 from being splashed with water and resulting in poor insulation.
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。
As seen from the center side of the washing tub 1, the clothes insertion port 4, the sliding surface 34 (second support means) of the flow path structure portion 7, the front edge portion 33 of the operation portion, the opening portion 32, and the detergent dissolution means 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 water flow surface 8a of the detergent dissolving means 8 are arranged. The detergent storage 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 7. Is done. Thereby, 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 (first support of the detergent dissolving means 8). Even when the detergent storage case 6 can only be supported outside the opening 32, the sliding mechanism of the flow path structure 7 is removed when the detergent storage case 6 is largely pulled out to the sliding surface 34 of the flow path structure 7. Since it can be supported by the moving surface 34 and the detergent storage case 6 does not fall off, the user can reliably put in the detergent.
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。
The sliding surface 34 (second support means) of the flow path structure portion 7 constitutes a part of the flow path structure section 7 so that the detergent storage case 6 can be connected to the detergent dissolution means 8 and the flow path structure section 7 only. Thus, the sliding surface 30 (first supporting means) of the detergent dissolving means 8 can be obtained simply by positioning the detergent dissolving means 8 and the flow path structure 7 with claws, screws, or the like. ), And the relative position of the sliding surface 34 (second support means) of the flow path structure 7 and the sliding surface 31 of the detergent storage case 6 is prevented from being displaced, making it difficult to pull out the detergent storage case 6. 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 detergent into the detergent inlet 58 of the washing tub 1, the detergent flows down to the detergent dissolving blades 57, and the stirring blades 56 are rotated during washing so that the detergent dissolves together with the stirring blades 56. The wings 57 can dissolve the detergent. When the tap water pressure is high, the detergent is put into the detergent storage case 6 that is freely opened and closed in the upper housing 3, and the detergent is dissolved and supplied to the washing tub 1 when supplying tap water. When the tap water pressure is low, When water is supplied in a bucket or the like without using water, the detergent can be dissolved in the detergent inlet 58 of the washing tub 1 and the detergent can be dissolved by the rotation of the stirring blade 56 during the washing operation.
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, the mixing chamber 24 and the crushing chamber 22 are partitioned by a partition wall 23, and a first flow down hole 25 through which water flows down to the mixing chamber 24 and a second downflow hole 26 through which water flows down into the crushing chamber 22. Are provided in communication with the flow path structure portion 7, and the detergent aqueous solution 9 is allowed to flow from the slit 21 that flows downward to the bottom of the crushing chamber 22. Thus, regardless of the condition 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 surely 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 channel structure 7 is low, and the flow rate of water flowing out from the first flow hole 25 and the second flow hole 26 communicating with the first flow hole 25 is low, the water level in the mixing chamber 24 is also slow. Ascending, the detergent in the mixing chamber 24 does not exceed the partition wall 23 at a time, and is dissolved over a sufficient time by the water from the first flow down hole 25 and then sent to the grinding chamber 22. For this reason, even when the tap water pressure is low, dissolution can be promoted and 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 7 is high, and the flow rate of water flowing out from the first flow hole 25 and the second flow hole 26 communicating with the first flow hole 25 is high, the water level in the mixing chamber 24 is Ascending quickly, the detergent in the mixing chamber 24 exceeds the partition wall 23 in a short time. Even in this case, it is possible to have time for mixing water and detergent until the partition wall 23 is exceeded. Since the flow rate of water from the second flow down hole 26 is also high, the detergent is crushed vigorously in the crushing chamber 22 and can be dissolved in a short time. For this reason, even if a tap water pressure is high, melt | dissolution can be accelerated | stimulated and it can supply to the washing tub 1, and a washing | 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 flowing water surface 8 a of the detergent dissolving means 8 toward the slit 21, and the tip of the pin 20 is inserted into the slit 21. Thereby, the detergent finely pulverized before passing through the slit 21 is further finely pulverized while passing between the pins 20 on the 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 storage case 6, the user sticks the detergent storage case 6 in and out of the washing machine every time the detergent is put into the washing machine. Since the detergent can be peeled off by the sliding pins 20 and the detergent can be prevented from being clogged by being stuck to the slit 21, efficient detergent dissolution can be realized over 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 pulverization chamber 22 region. Thereby, even when the tap water pressure is high and the flow rate flowing down from the first flow down hole 25 of the flow path structure portion 7 is large, the flow of the detergent aqueous solution 9 that has vigorously exceeded the partition wall 23 is crushed by the detergent aqueous solution speed adjusting wall 27. In the direction of the chamber 22, it can be changed downward in FIG. Therefore, since the detergent aqueous solution 9 tends to stay in the pulverization chamber 22 and the detergent aqueous solution 9 can be prevented from flowing down over the pulverization chamber 22 before the detergent dissolution proceeds, the detergent can be efficiently dissolved, and the cleaning performance 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 suppression wall 28 a is formed to extend in the flowing direction in the vicinity of the position facing the first flow down hole 25 of the flowing water surface 8 a of the detergent dissolving means 8. As a result, when the detergent storage case 6 is forgotten to be installed and operated, the water flows down from the first flow down hole 25 and the water splashes in all directions on the water flow surface 8a of the detergent dissolving means 8, but part of the water splash suppression wall. 28a, the flow changes upward. For this reason, it can suppress jumping ahead of an apparatus from the 2nd drainage part 12 side opening of the flowing water surface 8a of the detergent melt | dissolution means 8. FIG.
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 suppression wall 28a on the second drainage portion 12 side extends in a substantially J shape in a direction different from the flowing direction, the water flows down from the first flow down hole 25 and the water flows through the detergent dissolving means. When bouncing in four directions on the surface 8a, it is possible to suppress the water from bouncing from the drainage portion 12 side. The water splash suppression 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 flow down hole 26. Thereby, when the water from the 2nd flow down hole 26 splashes in four directions on the water flow surface 8a of a detergent melt | dissolution means, a part hits the water splash suppression walls 28b and 28c, and a flow changes upward. For this reason, since it can suppress jumping ahead of an apparatus, even if the detergent storage case 6 is removed, the user ahead of an apparatus is not wetted.
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 direction in which the detergent aqueous solution 9 flows in the water splash suppression walls 28b and 28c is open, the detergent aqueous solution 9 does not remain. A drainage hole 29 communicating toward the washing tub 1 is provided on the water flow surface 8a of the detergent dissolving means 8 in the vicinity of the water splash suppression wall 28a that is bent in a substantially J shape at one end on the second drainage portion 12 side. 1 is opened in a range inside the washing tank opening inner wall 13. Thereby, a part of the water flowing on the 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 is dammed by the water splash suppression wall 28a. Alternatively, it is possible to prevent the detergent aqueous solution 9 whose flow direction is suppressed from staying on the water surface 8a of the detergent dissolving means 8 and then drying to prevent only the detergent from adhering to the 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 water surface 8a of the detergent dissolving means 8 is configured to extend downward from a part of the upper housing 3, and its periphery is surrounded by the peripheral wall 8b of the detergent dissolving means 8, and its upper portion is covered with the flow path structure portion 7. Further, it is waterproofed by a second waterproof wall 17 configured integrally with the flow path structure 7. Thereby, the detergent dissolution means 8 and the water splash suppression walls 28a, 28b, 28c are molded in the vertical direction of FIG. 5, that is, in the same direction as the opening direction of the molding die of the upper housing 3 when being molded by the mold. Since it can be molded by moving the mold, it can be easily molded 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, the drainage hole 29 opens at a position facing one of the first flow down holes 25, so that the water flowing down from the first flow down hole 25 hits the water flow surface 8 a of the detergent dissolving means 8. Therefore, even if the detergent storage case 6 is not attached, it is possible to suppress water from splashing forward on the flowing water surface 8a of the detergent dissolving means 8.
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 storage case 6 is pulled out, the position is regulated by the claw 37 of the detergent storage case 6 and the claw 35 of the flow path structure portion 7. Thereby, a detergent and a softening agent can be put into the 1st storage chamber 14 and the 2nd storage chamber 15 by predetermined amount of drawers every time, and it is convenient. Furthermore, since the user can remove the detergent storage case 6 simply by pressing down the beam portion 36 of the detergent storage case 6, it is easy to use. Even if the engagement between the claw 37 of the detergent storage case 6 and the claw 35 of the flow path structure portion is increased, it can be removed simply by pushing down the beam portion 36 of the detergent storage 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 storage case 6 and the claw 35 of the flow path structure portion are located at substantially one center of the detergent storage case 6, the detergent storage case 6 is difficult to rattle from side to side and the beam of the detergent storage case 6 The operation of depressing the portion 36 can be performed with one hand, and can be easily removed, so that it is easy to use. Since the beam portion 36 of the detergent storage case 6 can be visually recognized in the state in which the detergent storage case 6 is pulled out, the method for removing the detergent storage case 6 can be easily determined visually 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 storage case 6 is attached, the beam portion 36 of the detergent storage case 6 is elastically bent downward and gets over, so that the tab 37 of the detergent storage case 6 and the tab 35 of the flow path structure portion 7 are engaged. Stop. Since the user can install the detergent housing case 6 at a predetermined position simply by pushing it in, the user does not need to apply any force other than the sliding direction of the detergent housing case 6 and is easy to use.
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。
At substantially the center of the detergent storage case 6, there is a claw 37 (first locking means) of the detergent storage case 6 and a claw 35 (second locking means) of the flow path structure portion 7. The support means 38 of the flow path structure 7 and the position restraining means 39 of the detergent storage case 6 are provided close to the claw 37 and the position away from the claw 35, that is, the left and right ends of the detergent storage case 6. Thereby, in order to enlarge the clothes insertion port 4, even when the distance from the claw 37 of the detergent storage case 6 to the rear end surface of the detergent storage case 6 is shortened, the detergent storage case 6 is arranged so that the detergent can be easily input. When opened, the support means 38 of the flow path structure 7 and the position restraining means 39 of the detergent storage case 6 are close to each other, so that the detergent storage case 6 is less rattling and it is easy to put in the detergent.
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 support means 38 of the flow path structure section 7 has the same cross section over the entire length of the flow path structure section lower surface 7b in the front-rear direction of the flow path structure section lower surface 7b, that is, in the sliding direction of the detergent storage case 6. 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. Accordingly, even when the detergent storage case 6 is designed to be horizontally long in order to increase the amount of detergent to be introduced, the movement of the left and right ends of the detergent storage case 6 is suppressed when the detergent storage case 6 is slid back and forth. Therefore, the detergent housing case 6 is less rattling and can be easily put into the detergent.
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 channel structure lower surface 7b, the sliding surface 34 of the channel structure 7, the claw 35 of the channel structure 7, and the support means 38 of the channel structure 7 are integrally formed, the channel structure The claw 35 of the section 7 and the support means 38 of the flow path structure section 7 can be configured by one part, are less likely to be misaligned, and reduce the shakiness of the detergent storage case 6. Even if the clearance between the support means 38 and the position restraining means 39 of the detergent storage case 6 is designed to be small, the sliding of the detergent storage case 6 can be prevented 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, 8, 9, and 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 is the first water supply means 48. Since the water is supplied to a position that is eccentric to the right side of the symmetrical, even if the tap water pressure is low and the shower water 50 cannot be fanned out, the shower water 50 can be uniformly soaked in the entire laundry 55, 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 path 41, and the water supply valve 18 and the flow path structure section 7 can be shared, so that the washing machine 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 washing tub 1 rotates in the clockwise direction, the laundry 55 located on the left side of the washing tub 1 moves toward the first water supply means 48 located on the left side of the washing 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 second water supply means 49 moves upward from the lower left side in order from the opposite side of the laundry 55 to the shower water. 50 is put on the laundry 55. Thereby, while repeating the 1st rotation state and the 2nd rotation state, the shower water 50 can be uniformly soaked in the whole laundry 55, and 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 rinsing operation is performed after the dehydrating operation, the laundry 55 is stuck around the washing tub 1 by centrifugal force due to the high-speed rotation of the washing tub 1, and therefore the first horizontal By directing 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 disposed adjacent to the left and right of the detergent storage case 6 and can share the flow path structure portion 7 and the water supply valve 18. The washing machine main body can be designed compactly, and the washing time can be shortened by putting the detergent aqueous solution 9 and the shower water into the washing tub 1 at the same time. In addition, although demonstrated by providing two water supply means, it is not limited to two, Even if it provides two or more water supply means, there exists the same effect.
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 is opened 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 water flow becomes thick and water flow that is hardly affected by surface tension or the like can be ejected radially from both ends, and water from the first horizontal opening 46 and the second horizontal opening 47 is formed between the end openings 51 as a film. The shower water 50 can be easily fanned out 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 including 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 channel cross-sectional area S2 of the first water pipe portion 43. Therefore, even if the tap water pressure is low, a constant water pressure corresponding to the water level continues to be applied to the first horizontal opening 46, so that the shower water 50 can be stably ejected. Can be easily spread in a fan shape.
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。
Since the inner surface of the jaw 52 is formed by extending a part of the spherical portion 45 to the edge of the first horizontal opening 46 by the diaphragm surface 53, the water pressure is applied perpendicularly to the surface of the spherical portion 45. The shower water 50 can be ejected straight from the horizontal opening 46, and the shower water 50 can be easily fanned out. Since the outer side of the jaw 52 has a receding surface 54 that recedes downward from the edge of the first horizontal opening 46 with respect to the extending direction of the first water pipe portion 43, Since one horizontal opening 46 can be molded and can be molded without adding a slide mechanism to the mold, it can be easily manufactured.
