に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain valve for controlling drainage in a tub of a washing machine or the like, and more particularly to an installation position of an oscillating spring suitable for reducing a load on a driving motor for opening and closing the valve. The present invention relates to a component configuration for opening and closing a bellows.

The operation control switch section 4 and a valve (bellows 12) storage section are formed. The operation cam 6 is rotated by a motor, and the sliding shaft 11 connected to the operation cam is reciprocated to open and close the valve. At the time, the pressing spring 1 provided inside the bellows
3. Press the bellows to stop water.

る。[0003] Position control of valve opening and valve closing is performed by the control switch. Further, as another structure, a drive unit (including a control switch unit) and a valve storage unit are separated from each other, and a sliding shaft is operated by a wire operated by the drive unit to open and close the valve.

開弁時は閉弁時に一定量たわんでいるバネを更に引上げ

その分負荷がかかる。In the case of the above prior art,
When the valve is opened, the spring, which has been deflected by a certain amount when the valve is closed, is further pulled up, so that the pressing force of the spring increases, and as a result, a load is applied to the drive motor.

の形状，構成が微妙に影響する。When the valve is closed, the force exerted by the spring acts as a negative load on the motor, and depending on the type of motor, it may not be possible to restart the motor due to the magnetic balance. Furthermore, when the valve is closed, the spring exerts a large force until the valve is closed, and the buckling of the spring causes the bellows to tilt due to the backlash of the sliding shaft, making the seating unstable, and possibly hindering water stopping. There is. In addition, the load of the driving motor and the stoppage of water by the valve are slightly affected by the shape and configuration of the operation cam for operating the valve, the sliding shaft that holds and slides the valve, and the connecting portions of both.

にある。The present invention has been made in view of the drawbacks of the conventional products, and has as its object to reduce the load on the driving motor, minimize the negative load area, and stabilize the seating of the bellows, thereby lowering the motor speed. The goal is to increase price and improve water sealability.

と略長方形リブの内壁間に設けることとする。The object of the present invention is to eliminate the use of a spring for pressing the bellows from the inside of the bellows, and to provide a connecting portion between an operation cam for opening and closing the valve and a sliding shaft for holding and reciprocating the bellows. The driving shaft portion is made into two parts, one of which has a substantially rectangular shape surrounded by a rib, and the other has a cylindrical shape, and a spring receiver provided in the substantially rectangular shape is rotatably engaged with the operation cam. This is achieved by adopting a configuration in which the However, the spring for pressing the bellows is provided between the spring receiver and the inner wall of the substantially rectangular rib.

保できる。According to the present invention, the load on the motor is greatly reduced only when the valve is closed, because only the force required to operate the cam by pressing is required to close the valve. Further, the negative load applied to the motor only acts instantaneously immediately after the opening operation at the time of opening the valve and is short in time and does not affect the restart after the motor is stopped. Further, since the force applied by the spring acts only at the time of closing the valve, the external force for inclining the sliding shaft is small, the seating of the bellows is stable, and the water sealing property at the time of closing the valve can be sufficiently ensured.

m程度で済む。FIG. 2 shows the valve closing state of the present invention, in which the operation cam 6 is stopped with the sliding shaft 11 pressed. At this time, the spring receiver 9 is at a position for pressing the oscillating spring 10, and this pressing force is transmitted to the bellows 12 via the connector 8 and the sliding shaft 11 to stop the water. The pressing force depends on the surface area of the valve closing portion of the bellows 12, but if it is about 1.2N, the water can be reliably stopped.
Also, just before the valve 3 is closed, only a force in the rotational direction for applying a pressing force necessary for closing the valve 3 is applied to the motor 3, which is 1.2 N · c.
m is enough.

くことができる。FIG. 3 shows an intermediate state before the valve is closed to the fully opened state, in which the fitting shaft 6a of the operation cam 6 is rotated by 90 ° from the valve closing position. At this time, the bellows is retracted by the operation cam 6 via the sliding shaft 11 and the connector 8, and is in a half-open state. The load on the motor 3 gradually decreases when the valve-opening operation starts, and disappears when the bellows is released from being pressed. The motor load at this position is determined only by the reaction force of the bellows rigidity and the sliding resistance of the sliding shaft 11. It is very small.
In addition, the connector 8 moves following the rotation of the fitting shaft 6a of the operation cam 6, and can be arbitrarily tilted with the insertion port 11c of the sliding shaft 11 as a base point.

ことができる。FIG. 4 shows a fully opened state, in which the bellows is further retracted from the position shown in FIG. 3 to reach the fully opened position. This position is a drainage state when the washing machine is assembled, and is held until the water in the tub is completely drained. The motor load at this position is the same as in FIG. From this state, the operation cam 6 is further moved.
2 can be returned to the valve-closed state of FIG.

的を達することが可能である。Another embodiment of the present invention will be described with reference to FIG. In the above-described embodiment, the sliding shaft 11 and the connector 8 are described as separate bodies, and are described as being inserted and fitted for connection. However, as shown in FIG. It is possible to achieve the purpose.

可能性があり相反する要素を持っている。However, in the case of the structure shown in FIG. 5, the connecting portion 8a between the sliding shaft and the connector needs to bend following the rotation of the fitting shaft 6a of the operation cam 6, and the bent portion has a thickness. The load on the motor 3 is reduced as the thickness is reduced. On the other hand, if the wall thickness is thin, it may buckle in an environmental test or the like when pressed by the oscillating spring 10 at the time of closing the valve, which has contradictory elements.

になる可能性がある。For this reason, it is necessary to select the thickness, the material, and the like based on the load torque of the motor, the application force of the oscillating spring, and the like, which is technically difficult. Considering this point, it is considered that the separate body is more advantageous, but there is a possibility that it is disadvantageous in terms of price because the number of parts increases.

印加されないためモーターの負荷は大幅に軽減できる。According to the present invention, the oscillating spring for pressing the bellows to close the valve is provided at the connection between the operation cam and the sliding shaft which reciprocates by the rotation of the operation cam, so that the load on the motor is reduced. Since only a force for operating the pressing at the time of closing the valve with the operation cam is applied, the load on the motor can be greatly reduced.

Further, the external force for inclining the sliding shaft at the time of closing the valve is very small, and the seating of the bellows held thereby is stable, and the water-sealing property at the time of closing the valve is ensured.
