ぱられ、これにより排水弁が開放動作される。(Prior Art) A conventional example of this type of drain valve opening / closing device will be described with reference to FIG. Reference numeral 1 denotes an operation lever supported via a shaft 2, which can be rotated within a range between a closing operation position A and an opening operation position B. A rotation lever 3 is rotatably supported via a shaft 4, and the center of the rotation shaft 4 is the rotation range between the closing operation position A and the opening operation position B of the operation lever 1. Is at a position C that bisects Such turning lever 3
Has a first lever portion 5 extending downward from the center of rotation toward the shaft 2 side of the operating lever 1 and a second lever portion 6 extending obliquely upward toward the closing operation position A side. A pull-up string 7 for pulling up a drain valve (not shown) is connected to the tip end portion of the first lever portion 5. Meanwhile, the second
The engaging projection 6a protruding from the tip of the lever portion 6 is engaged with the elongated hole 8 formed in the operation lever 1. in this case,
When the operating lever 1 is in the closing operation position A, the drain valve closes the drainage port, and when the operating lever 1 is rotated from this position to the opening operation position B, the rotating lever 3 rotates in the clockwise direction in the drawing. The pull-up string 7 is moved and pulled to the left side in the drawing, whereby the drain valve is opened.

なっていた。However, in the conventional structure described above, the center of rotation of the rotating lever 3 is at the position C that bisects the rotating range between the closing operation position A and the opening operation position B of the operation lever 1.
The rotation center of the rotation lever 3 is located relatively far from the closing operation position A. Therefore, when the operation lever 1 is in the closing operation position A, the second lever portion 6 is largely rotated to the closing operation position A side to increase the angle θ between the second lever portion 6 and the operation lever 1. Must. Thus, from the operation lever 1 to the second lever portion 6
When a force f is applied to the force f, the moment M of the force f around the rotation center of the rotation lever 3 is the force f and the arm p of the moment (the length of a perpendicular line drawn from the rotation center to the action line of the force f). ) And product. That is, M = f × p. In this case, since the direction of the force f is perpendicular to the operation lever 1, if the angle θ is large at the beginning of the drain valve opening operation, the arm p of the moment is correspondingly increased.
Becomes shorter and the moment amount becomes smaller.
The rotation lever 3 cannot be rotated unless the value is increased, and the operation force F 3 of the operation lever when opening the drain valve is heavy.

ーの操作力が重くなるという問題点があつた。(Problems to be Solved by the Invention) As described above, in the conventional structure, the rotation center of the rotation lever bisects the rotation range between the closing operation position and the opening operation position of the operation lever. Since it is in the position, the operation force applied to the operation lever at the beginning of the drain valve opening operation is not effectively converted into the turning force of the rotating lever, and the operation force of the operation lever when opening the drain valve becomes heavy.

にある。The present invention is intended to solve such problems,
Therefore, it is an object of the present invention to provide a drainage valve opening / closing device for a washing machine or the like that can reduce the operating force of the operating lever when the drainage valve is opened.

である。[Structure of the Invention] (Means for Solving the Problems) In the drainage valve opening / closing device of the present invention, the rotating lever is rotated by rotating the operating lever between the closing operation position and the opening operation position. The opening / closing operation of the drain valve, the rotation center of the rotation lever is located at a position that bisects the rotation range between the closing operation position and the opening operation position of the operation lever. It is biased to the closing operation position side.

る。(Operation) Since the rotation center of the rotation lever is biased to the closing operation position side, the rotation center of the rotation lever approaches the closing operation position. Therefore, the angle formed between the operation lever and the turning lever at the beginning of the drain valve opening operation can be reduced, and the arm of the moment of force around the turning center of the turning lever can be lengthened. Thus, the operating force applied to the operating lever can be effectively converted into the turning force of the turning lever.

バー18とのなす角度を小さくした構成となっている。(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. 11 is the bottom plate of the operation box provided on the upper rear side of the washing machine,
12 is a water supply gutter for guiding tap water to a washing tank or a dehydrating tank, 13
Is a support for supporting the drain valve 14, and is biased downward by a compression spring 15 provided on the upper portion thereof, whereby the drain valve 14 is brought into a state of being pressed against a drain port (not shown). 16
Is a pull-up string which is an interlocking member connected to the support 13 of the drain valve 14, and is led out into the operation box through an insertion hole 17 formed in the bottom plate 11. On the other hand, 18 is an operation lever rotatably supported on the operation box side, and its specific support structure is as shown in FIG. 3 in which the lower end of the operation lever 18 is attached to the shaft 20 of the fixture 19 attached to the bottom plate 11. The hole 18a is fitted and the projection 11a of the bottom plate 11 prevents the bottom plate 11 from coming off in this state. The operation lever 18 is rotatable in the left-right direction within the range between the closing operation position A and the opening operation position B, with its upper end protruding from a slit (not shown) on the upper surface of the operation box. ing.
Reference numeral 21 is an operation knob provided so as to be slidable in the left-right direction along the upper surface of the operation box, and by inserting and engaging the upper end of the operation lever 18 into an engagement hole 22 formed in the lower surface portion of the operation knob 21, The linear slide displacement is converted into the rotational displacement of the operation lever 18. Reference numeral 23 denotes a rotating lever, which is formed integrally with first and second lever portions 25 and 26, which are a pair of lever portions extending in different directions, at both ends of the shaft 24. The shaft 24 of the rotation lever 23 is rotatably received and supported by a pair of support pieces 27, 27 projecting upward from the fixture 19. Thus, in the present embodiment, the center of the shaft 24, which is the center of rotation of the rotating lever 23, divides the range of rotation of the operating lever 18 between the closing operation position A and the opening operation position B into two equal parts. It is biased closer to the closing operation position A than C (see FIG. 2). Then, the tip portion of the pulling cord 16 pulled out substantially leftward from the insertion hole 17 of the bottom plate 11 is connected to the tip portion of the first lever portion 25,
On the other hand, the engaging protrusion 28 formed at the tip of the second lever portion 26.
(See FIG. 3) is inserted and engaged in a long hole 29 formed in the operation lever 18. In this case, when the operation lever 18 is in the closing operation position A, the first lever portion 25 is
The second lever portion 26 is directed obliquely upward toward the closing operation position A side while facing the shaft 20 side of 18, and the pivot center of the pivot lever 23 is directed toward the closing operation position A side. Due to the change, the angle between the second lever portion 26 and the operating lever 18 is necessarily reduced.

置Ｂに至り、その位置に保持される。Next, the operation of the above configuration will be described. Operating lever 18
Is in the closing operation position A, the drain valve 34 is in a state of closing the drain port. From this position, operation knob 21
When the operation lever 18 is rotated to the right side, that is, the opening operation position B side by sliding the right side of the lever, the rotation lever 23 is rotated in the clockwise direction in the drawing in conjunction with this, and the pulling cord 16
Is raised. By pulling up the pulling cord 16, the drain valve 14 is pulled up against the biasing force of the compression spring 15,
The drain is opened. In the first half of the opening operation of the drain valve 14, the tension T of the pulling cord 16 (see FIG. 2) gives a moment in the counterclockwise direction in the drawing to the rotating lever 23, so that an operation force F that opposes the moment. It is necessary to add 1 to the operation knob 21. However, after the connection point between the first lever portion 25 and the pulling cord 16 becomes higher than the rotation center of the rotating lever 23 to some extent during the operation, the direction of the moment due to the tension T of the pulling cord 16 is reversed. It becomes a clockwise direction in the figure, and even if no operating force is applied, the tension T naturally causes the turning lever to rotate.
23 rotates in the clockwise direction and the operating lever 18 reaches the opening operation position B and is held at that position.
以上のような開放操作時における操作力F1の変化を第４
図に示す。この第４図から明らかなように開放操作の開
始後暫くして操作力F1が最大になるが、この操作力F1は
点線で示す従来の操作力F3に比して小さくなっている。
以下、その理由を説明する。The change in the operating force F 1 during the opening operation as described above is
Shown in the figure. As is apparent from FIG. 4, the operating force F 1 reaches its maximum shortly after the opening operation is started, but this operating force F 1 is smaller than the conventional operating force F 3 shown by the dotted line. .
The reason will be described below.
即ち、回動レバー23の回動中心を閉鎖操作位置Ａ側に偏

Ａに近寄った形態となる。このため、必然的に排水弁14

で従来と同じ大きさの回動モーメントを回動レバー23に
与えることができ、換言すれば操作力F1を有効に回動レ
バー23の回動力に変換することができるから、操作力F1
を軽くすることができるものである。That is, since the rotation center of the rotation lever 23 is biased to the closing operation position A side, the rotation center of the rotation lever 23 comes close to the closing operation position A. Therefore, the drain valve 14 is inevitable.
The angle formed between the operation lever 18 and the second lever portion 26 of the turning lever 23 at the beginning of the opening operation of the is reduced, and the arm p of the moment of the force f around the turning center of the turning lever is smaller than in the conventional case. And become longer. Therefore, the operating force F 1 is smaller than before.
In can give rotational moment of the same size as conventional in the rotating lever 23, because it can be converted to effectively turning force of the rotating lever 23 the operation force F 1 In other words, the operation force F 1
Can be lightened.
一方、排水弁14を閉鎖動作させるには、操作摘み21を閉

によって、操作レバー18を左側に回動させて、回動レバ
ー23を図示反時計回り方向に回動させる。操作開始当初
は、回動レバー23の回動により引上げ紐16が若干引上げ
られるため、操作力F2を必要とするが、その後暫くすれ
ば引上げ紐16の張力Ｔによるモーメントの方向が反転し
て図示反時計回り方向となるから、操作力を加えずとも
その張力Ｔによって自然に回動レバー23が反時計回り方
向に回動して操作レバー18が閉鎖操作位置Ａに至り、そ
の位置に保持される。この過程で、引上げ紐16が下げら
れるから、排水弁14が下降して排水口を閉鎖した状態に
なる。On the other hand, in order to perform the closing operation of the drain valve 14, the operation knob 21 is slid from the closing operation position A to the opening operation position B, whereby the operation lever 18 is rotated to the left, and the rotation lever 23 is rotated counterclockwise in the figure. Rotate in the rotating direction. At the beginning of the operation, since the pulling cord 16 is slightly pulled up by the rotation of the turning lever 23, an operating force F 2 is required, but after a while, the direction of the moment due to the tension T of the pulling cord 16 is reversed. Since it is the counterclockwise direction in the drawing, the rotating lever 23 naturally rotates counterclockwise by the tension T without applying an operating force, and the operating lever 18 reaches the closing operation position A and is held at that position. To be done. In this process, since the pulling string 16 is lowered, the drain valve 14 is lowered and the drain port is closed.
以上のような閉鎖操作時の操作力F2の変化を第４図に示
している。この第４図から明らかなように、操作力F2が
零になる位置を従来と同じく開放操作位置Ｂ側に偏倚さ
せた構成にすれば閉鎖操作当初における操作力F2を従来
の操作力F4と同じように小さくできる。FIG. 4 shows the change in the operating force F 2 during the closing operation as described above. As is apparent from FIG. 4, if the position where the operating force F 2 becomes zero is biased to the opening operating position B side as in the conventional case, the operating force F 2 at the beginning of the closing operation is the conventional operating force F 2. Can be as small as 4 .
また、本実施例では、排水弁14の開放操作時の操作力F1
を小さくすることができるから、この操作力F1と閉鎖操
作時の操作力F2との差を従来よりも小さくすることがで
きて、使用者に与える操作感を良くすることができる。Further, in this embodiment, the operating force F 1 at the time of opening the drain valve 14 is
Therefore, the difference between the operating force F 1 and the operating force F 2 at the time of the closing operation can be made smaller than in the conventional case, and the operation feeling given to the user can be improved.
尚、上記実施例では排水弁14を上下動させることによっ

い。In the above embodiment, the drainage valve 14 is configured to be opened and closed by moving the drainage valve 14 up and down, but the invention is not limited to this, and for example, a valve case having a drainage valve installed in a drainage path leading to the drainage port. Alternatively, the drain valve may be opened and closed by displacing the drain valve in a predetermined direction in the valve case based on the rotational displacement of the rotary lever.

Therefore, the angle formed by the operation lever and the rotation lever at the beginning of the drainage valve opening operation. Can be reduced, and the operating force applied to the operating lever can be effectively converted into the turning force of the rotating lever,
As a result, it has an excellent effect that the operation force of the operation lever at the time of opening the drain valve can be lightened.
