本発明は、短周期で洗濯機用モータを自動反転
させるのに好適な洗濯機用モータの制御装置に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a washing machine motor control device suitable for automatically reversing the washing machine motor in short cycles.
近年、回転翼を長周期で高速回転させる方式
（いわゆるパルセータ方式）に代えて、回転翼を
短周期で正逆転させる方式（いわゆる、アジテー
タ方式）が開発されている。 In recent years, instead of a method in which the rotor blades are rotated at high speed over a long period (so-called pulsator method), a method in which the rotor blades are rotated forward and backward in short periods (the so-called agitator method) has been developed.

イツチが用いられる。 Generally, in order to rotate the rotor blades forward or reverse, the washing machine motor that drives the rotor blades is rotated forward or reverse. To change the washing machine motor between forward and reverse directions, a reversing switch is used which switches the contacts using a cam plate rotated by a timer motor.

を持ち上げるための、傾斜面Ｗが必要である。 Showing the operating status of reversing switch 1 and cam plate 2,
Defects will be explained using A, B, C, and D in Figure 1. Three types of cam surfaces are formed on the cam plate 2: a cam surface X for forward rotation, a cam surface Y for stopping, and a cam surface Z for reverse rotation. As 1a slides, contact c, which is moved up and down by contact leg 1a, is brought into contact with contact a and contact b alternately. With this configuration, from the forward rotation cam surface X to the pause cam surface Y, and from the pause cam surface Y to the reverse rotation cam surface Z.
When the armature leg 1a moves, the inclined surface W is not required, but when the armature leg 1a moves from the reverse rotation cam surface Z to the forward rotation cam surface X, the armature leg 1a
An inclined surface W is required to lift the .

の正逆転時間が短くなる。 If the slope W is steep, the sliding resistance between the armature leg 1a and the slope W will be large, and the operability of the cam plate 2 will be extremely poor. On the other hand, if the slope W is gentle, the rest time of the reversing switch 1 becomes longer, and the time required for forward and reverse rotation of the washing machine motor connected to the reversing switch 1 becomes shorter.

る。 An object of the present invention is to solve the above-mentioned drawbacks and shorten the downtime of the reversing switch even when a reversing switch is used, in which the contacts are switched by a single cam plate and the washing machine motor is rotated in the forward and reverse directions. To provide a control device for a washing machine motor which can be set and which does not deteriorate the operability of a cam plate.

The washing machine motor 5 is rotated in the forward and reverse directions by S 1 and S 2 . When choosing gentle washing or gentle rinsing,
The manual changeover switch 6 is opened, and the washing machine motor 5 is rotated in the forward and reverse directions using only the reversing switch S1 . If only the reversing switch S1 is energized, the rest time of the washing machine motor becomes longer, the number of forward and reverse rotations of the rotor blade decreases, and the washing power or rinsing power becomes weaker.

Contacts a and b of the reversing switch S2 and contacts a and b of the reversing switch S2 are energized alternately as shown in Figure 4, so the contact life is doubled compared to when only reversing switch S1 is used. It can be extended. Furthermore, since it is possible to take a long pause time between switching from contact b of reversing switch S 1 to contact a again, and to operate reversing switch S 2 during this pause time, as shown in FIG. The angle of inclination of the inclined surface W can be set sufficiently small. Furthermore, since the contact a of the reversing switch S2 can be closed at any time during the resting time of the reversing switch S1 , it is possible to set the resting time of the washing machine motor 5 to a very small value of 1 second or less. It is.
