取りつけ構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine that rotates a pulsator placed at the inner bottom of a washing and dehydrating tank during washing, and rotates the washing and dehydrating tank during dehydration. The present invention relates to a mounting structure for a balance ring placed on the upper opening edge of a washing and dehydrating tub.
従来のこの種洗濯機の基本構成は、一般に第１図に示す
ようになっている。図において、１は外筐体、２は洗濯
時水を貯える水受槽、３は合成樹。The basic configuration of a conventional washing machine of this type is generally as shown in FIG. In the figure, 1 is the outer casing, 2 is a water tank that stores water during washing, and 3 is synthetic wood.
脂製の洗濯兼脱水槽で、その内底部にパルセータ４を配
し、洗濯時はパルセ〜り４を回転させ、脱水時は洗濯兼
脱水槽３を回転させて、その側壁に設けた複数の穴６か
ら水を水受槽２に排出させる。It is a washing and dehydration tank made of fat, and a pulsator 4 is arranged at the inner bottom of the tank.The pulsator 4 is rotated during washing, and the washing and dehydration tank 3 is rotated during dehydration. Water is discharged from the hole 6 into the water receiving tank 2.
６は洗濯兼脱水槽３の上方開口縁に嵌合し、複数個のネ
ジ７等で固着した塩水等を封入した合成樹効果をあげ゛
る為に設けである。Reference numeral 6 fits into the upper opening edge of the washing and dewatering tank 3, and is provided to enhance the effect of a synthetic tree filled with salt water, etc., which is fixed with a plurality of screws 7 and the like.

８ｂによって前記外筐中上部の角隅から球面骨は等で吊
下げ支持されている。8/'i, a drain valve attached to the outer bottom of the water receiving tank 2 is opened and closed by a control signal from a time switch 10 etc. in the operation box 9 to control the drain. Reference numeral 11 denotes a motor, which transmits driving force to the pulley 12 by belt transmission, and the washing/dehydration switching mechanism 13 transfers the driving force from the washing shaft 14 to the pulse generator 4 during washing, and from the spindle shaft 15 via the flange 16 during spin-drying. The information is transmitted to the washing/dehydration tank 3 fixed to this. 17 is the motor 11 and the washing/dehydration switching mechanism section 1
3 is a support plate attached to the support rod 1 via a vibration isolator 18a constituted by a spring or the like.
The spherical bone is suspended and supported from the corner of the middle upper part of the outer casing by 8b.
以上のような構成において、前記した脱水回転時の不釣
り合い力について述べると、脱水回転数が通常８ｏｏ〜
９００ｒｐｍであることから、洗濯物の小さな不釣り合

。又、前述のように、この振動系は外筐体１に釣り下げ
られ且つ釣り下げ部の重心はモータ１１や洗濯脱水切換
機構部１３等の重量の大きいものが下部に配されている
為に、洗濯兼脱水槽３の下方に位置している。In the above-described configuration, the unbalanced force at the time of spin-drying rotation mentioned above is explained when the spin-drying speed is usually 8oo~
Since the speed is 900 rpm, a small unbalanced distribution of the laundry results in a large unbalanced force, and a large force is also applied to the balance ring 6, which exerts a corresponding balancing force. Moreover, as mentioned above, this vibration system is suspended from the outer casing 1, and the center of gravity of the suspended part is because heavy components such as the motor 11 and the washing/dehydration switching mechanism 13 are located at the bottom. , is located below the washing and dehydrating tank 3.
前記不釣り合い力による重心まわりのモーメントを小さ
な釣り合わせ力で釣り合わせる為には、改心より遠い所
に前記バランスリング６を配する方かよい。従って、前
記バランスリング６は、洗濯兼脱水槽３の上方開口縁に
配しである。In order to balance the moment around the center of gravity due to the unbalanced force with a small balancing force, it is better to arrange the balance ring 6 at a location farther from the center of gravity. Therefore, the balance ring 6 is arranged at the upper opening edge of the washing and dehydrating tub 3.
このような理由で、従来は、前記バランスリング６を洗
濯兼脱水槽３の上方開口縁に嵌合し、且つ複数のネジ７
で堅固に固着していた。For this reason, conventionally, the balance ring 6 is fitted to the upper opening edge of the washing and dehydrating tub 3, and a plurality of screws 7 are attached to the balance ring 6.
It was firmly fixed.

、その材料費は高価なものとなっていた。The plurality of screws 7 are made of stainless steel or the like in order to prevent them from rusting due to bleach, salt water, etc. and becoming insufficient in strength, and to prevent rust from adhering to clothing. Or they were treated with anti-corrosion treatment, making the materials expensive.

トの面で有利である。しかし、合成樹脂製のバランスリ
ング６の容器本体と、合成樹脂製の洗濯兼脱水槽３を一
体に形成することは、金型構造上きわめて難しい。Here, the balance ring 6 has a simple structure as described above, and there is no need to worry about failure, and since it is not used in a way that causes wear, it is a component that fully performs its functions semi-permanently. Therefore, it will not be removed from the washing/dehydration tank 3 for repairs or the like. Therefore, as mentioned above, there is no need to make it removable with the screws 7, but rather it is more robust if it is integrally formed or fixed to the washing/dehydration tank 3, and also because it does not use the screws 7, it can save resources and reduce costs. It is advantageous in terms of cost. However, it is extremely difficult to integrally form the container body of the balance ring 6 made of synthetic resin and the washing/drying tank 3 made of synthetic resin due to the structure of the mold.
又、第２図のように、バランスリング６の容器れば金型
構造上簡単にはなるが、この為に洗濯兼脱水槽３と水受
槽２の間隙を大きくせねばならず、洗濯兼脱水槽３の大
きさに対し水受槽２が必要以６ｔ 。Also, as shown in Fig. 2, although the mold structure is simplified if the balance ring 6 is a container, the gap between the washing and dehydration tank 3 and the water receiving tank 2 must be made large for this purpose. Compared to the size of water tank 3, water tank 2 requires 6 tons.

両者を超音波溶着によって固着するものである。In view of the problems of the conventional art described in L, the present invention provides a balance ring 6 made of synthetic resin and a washing/drying tub 3 made of synthetic resin. Instead, they are fixed together in order to obtain a water-saving effect, and more specifically, they are fixed together by ultrasonic welding.

３外表面に形成している。The present invention will now be described in detail. In FIGS. 3 to 7, a synthetic resin balance link 6 containing salt water or the like is fitted to the upper opening edge of the synthetic resin washing/drying tank 3. At a plurality of locations, the side wall of the washing and dehydrating tank 3 and the outer peripheral wall of the balance ring 6 are ultrasonically welded from outside the washing and dehydrating tank 3. 9 indicates the welded portion, and the individual shape of this welded portion 19 consists of a pair of sides having a length Hl that are substantially parallel in the circumferential direction of the washing/dehydration tank 3, and a length H2 representing the length of the dehydration rotation. It has a substantially rectangular shape consisting of a pair of sides that are substantially parallel in the horizontal direction, and a substantially flat surface where Hl>H2 is formed on the outer surface of the washing and dehydrating tub 3.
一般にバランスリング６は、その高さが大きい方が、同
容積に対し、大きな釣り合わせ力を発揮するため、洗濯
兼脱水槽３に下半分程度嵌合させて、洗濯兼脱水槽３の
内容積を大きく、汀つ、バランスリング６の高さを大き
くとれる構造にしている。従って、前記した溶着部１９
および嵌合部は、バランスリング６のＦ方に位置する。In general, the larger the height of the balance ring 6, the greater the balancing force for the same volume. The balance ring 6 has a structure that allows the height of the balance ring 6 to be increased. Therefore, the welded portion 19 described above
The fitting portion is located on the F side of the balance ring 6.
ところで、溶着強度は溶着面積に比例するので、溶着面
積は大きくなければならないが、第７図のように溶着部

に、Ｈｌ〉Ｈ２として、溶着面積を大きくしなければな
らなかった。By the way, the welding strength is proportional to the welding area, so the welding area must be large. However, if the welding area 19 is made larger in the vertical direction as shown in Fig. 7, that is, H2>Hl, the melting during welding will be Resin flows out onto the inner wall of the washing/dehydrating tub 3 from the gap between the balance ring 6 and the washing/dehydrating tub 3 due to distortion during molding, and when it cools and hardens, it becomes an irregularly shaped convex portion 2o, which prevents washing. It may damage things. Therefore, the welded part 19 had to be as narrow as possible in the vertical direction (and the welded area had to be made large so that Hl>H2 so that the molten resin would not flow out to the inner surface of the washing/dehydration tank 3). .

。Further, a substantially circular or rectangular recess 21 with a depth tl is formed at the substantially center of the substantially rectangular welded portion 19 using an ultrasonic welding tool horn. For the wall thickness t2, t1'; t2 is set. In order to increase the welding strength, it is necessary to sufficiently melt the outer surface of the balance ring 6 of the welding part 19. Therefore, the tip of the ultrasonic welding tool horn is inserted into the welding part 19 from the outside of the washing and dewatering tank 3. However, when the tip of the tool horn digs deeply into the outer wall of the balance ring 6, not only the outer surface of the balance ring 6 melts, but also the resin on the inner surface, causing a pinhole to form on the outside of the welded part of the balance ring 6. The salt water, etc. that is formed and sealed inside may leak out due to centrifugal force during spin-drying. Therefore, the depth t of the recess 21 formed by the biting of the tool horn is equal to
For the wall thickness t2 of 9, it must be tlL;t2.
また、溶着強度は、工具ホーンによる加圧力に比例する
が、洗濯兼脱水槽３およびバランスリング６はいずれも
円形の為、溶着部１９は曲率をもつ面となる。溶着部１
９が平面になるように、これらの部品を成形することは
できるが、組立嵌合時、作業が困難となる。Further, the welding strength is proportional to the pressure applied by the tool horn, but since both the washing and dewatering tub 3 and the balance ring 6 are circular, the welded portion 19 becomes a surface with curvature. Welded part 1
Although these parts can be molded so that 9 is flat, it becomes difficult to assemble and fit them together.
そこで、工具ホーンに前記曲率と同等の曲率をもたせれ
ば、溶着面に均一に工具ホーンが圧着することになるが
、これでは工具ホーンの位置がずれた場合、圧着は不均
一となる。Therefore, if the tool horn has a curvature equivalent to the above-mentioned curvature, the tool horn will be evenly crimped onto the welding surface, but if the tool horn is misaligned, the crimping will be uneven.
本実施例によれば、前記溶着部１９の略長方形状部分の
外表面に、縦方向の１組の辺にそって１対の深さｔ３で
ｔ３〈ｔｌ の溝部２２を工具ホーンで形成している。According to this embodiment, a pair of grooves 22 having a depth t3 and a depth t3<tl are formed on the outer surface of the substantially rectangular portion of the welded portion 19 along a pair of vertical sides using a tool horn. ing.

が得られた。That is, the tool horn crimps the welded part 19 with its tip and the protruding strips provided on a pair of sides of the rectangular part,
Even if the position of the tool horn is slightly deviated from the curvature, sufficient welding strength can be obtained by the groove 22. Also, by setting t3 x tl, the welding strength of the welded portion 19 is made uniform around the recessed portion 21,
Prevented the occurrence of uneven welding. According to such a configuration, a fixing strength equal to or higher than that of the conventional fixing method using screws was obtained.
