御の安易かつ信頼度の高い排水制御装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain valve of an automatic washing machine, and in particular, it uses a small motor that does not generate a large impact noise when the valve is opened and closed, is almost silent, and is easy to control. The present invention relates to a highly reliable drainage control device.

The operation was performed using a large electromagnetic solenoid. Therefore, the operation sound was postponed, and there was a big sound of collision with the same metal, which was a big weak point. It should be noted that although no electromagnetic solenoid is used, a small motor is required to have a large output torque in order to perform the collective operation of the functions of the above-mentioned three parties. It is used, leading to an increase in the number of parts and a decrease in reliability.

のである。The object of the present invention is to divide the drain valve to open / close, to engage / disengage the clutch, to engage / disengage the brake, and separately for each of the three operations. The drain valve uses a small synchronous motor,
The rotation position is controlled by a simple cam and contact piece.

行ったものである。[Means for Solving the Problems] This is because the operating force is simply reduced to 1/3 by dividing the functions of the three parties, so that the motor may be of a smaller size and with a low output torque, and the opening and closing of the valve , In the rotation of the final output shaft, it returns to the original position in one rotation.
By opening at a so-called 180 ° half rotation and closing again at the next 180 ° half rotation (the small motor can only rotate in the same direction or both (without a reverse rotation stopper). ), Not the rotation control or the time control, but the position control, and the valve opening / closing is performed with the simple and accurate control.

動作をすることが出来ないことになる。これでは成り立
たない。[Function] Opening and closing the valve does not cause much trouble, but
When closed, the most important predictor is the occurrence of water leaks without returning completely. This was dealt with by controlling the position of the motor rotation after allowing a margin after the valve body was closed when returning. Furthermore, in position control, the contact is switched every half rotation, but if a power outage occurs during the half rotation, or during the same, the user inputs an operation change signal or turns the power on. When the valve is turned off, for example, when the valve is being opened to drain water, the valve is stopped, and when the washing signal is immediately switched, the valve is stopped halfway open. At this time, the signal for closing the valve must be accepted, but it is difficult to use the leaf position control or to use a separate means. Therefore, this means that the valve cannot be closed and the washing operation cannot be performed. This is not true.

御は完了した後に信号切換えとなるからである。Therefore, in the present invention, the number of rotations of the motor is increased as much as possible to shorten the control time for half rotation, and the above-mentioned probability of malfunction due to a change in the operation signal is reduced. The rotation speed of the motor at this time is preferably 10 rpm or more. This is because the control time for half rotation is within 3 seconds, which is a short time, and therefore the operation time is longer, and the signal switching is performed after the half rotation control is completed.

とになるが、確実に行うことが出来るものである。The problem of power failure is not possible even with the above-mentioned measures taken within 3 seconds. For this, a capacitor having a selected capacity is provided to charge the power for 3 seconds even if the power is cut off. In addition, the work of half rotation by the given signal is finished, or the way of giving the signal is special, and from the state where the signal is received, special processing is performed and the signal of the given place There is also a method of performing an initialization operation that returns to the place. It operates based on the received signal without reading where the position control is.However, if the leaf position is in the middle and the contact for the received signal is open, only the signal is accepted as it is. Then, the motor is not rotated, and then a signal opposite to the original signal is input. In this state, since the contact is closed in this state, the motor rotates according to the signal and stops at half rotation. At this time, when the initial signal is input again, the motor is rotated based on this signal, and the motor stops at the position indicated by this signal. When sending a so-called drainage signal, put three signals (drainage signal-> water supply signal-> drainage signal) (as necessary at the beginning) to make sure that they are initialized and stop where you want them, and proceed to the next. Can be done. This takes 9 seconds in total if one signal is 3 seconds, but it can be surely performed.

When the signal is received at the drain signal terminal 52, the triac 50 is turned on. When the neutral leaf 33 and the drainage signal leaf 35 are connected, the motor 38 starts rotating, the cam 30 rotates clockwise in the embodiment, the pin 30a also moves the mover 29, and the spring is pushed by the push spring 44. The moving arm 43 is moved by the tension spring 45 having a constant constant. By doing so, the lip portion 42a is separated, the water seal is released, and water is allowed to pass through. The motor 38 rotates,
The dowel 41 is moved at the step of the leaf cam 30b by 180 °, so-called half rotation, and the neutral leaf separates from the drainage leaf 35 after all three lines in the state (II) are closed. Due to this separation, the rotation of the motor 38 is stopped, and the valve is stopped when it is fully opened.

Since the triac 51 is turned on and the neutral leaf 33 and the water supply leaf 34 are connected, the motor 38 is also rotated, and the leaf is closed in the opposite direction to the drainage (II). The same state as the above is created, the process returns to (I), and the motor 38 stops.

If the configuration is in the first condition and each signal is given to the leaf next, assuming that the time required for half rotation of the motor 38 is 3 seconds at 10 rpm, a margin of about 30% is set for about 4 seconds, and each try is performed. It is not allowed to make up signals at the same time.

The state of contact is taken. That is, the state where the neutral leaf is not in contact with any leaf does not occur. Therefore, after the power failure, the small switch can be turned, and the drain valve can be driven according to the washing program.

By placing the drainage hose in the left-right symmetrical position, when replacing the drainage hose in the left-right direction, the clip 27 was conventionally loosened and the entire direction was changed, but the clip 27 part remains the same. There is also an advantage that it can be positioned and the reliability of the water seal part is further improved.

ない。Next, as shown in FIG. 7, a neutral leaf (o) and a neutral leaf (o) are provided as means for solving malfunctions such as short-time signal change, power failure during rotation, and reverse input of the next signal. In the drainage signal leaf (b) and the water supply signal leaf (a), when the drainage signal is first put in the state where o-a is in contact,
Even though there is no contact between −b, as described above, the signal of triac on is input for the required time of half rotation + α by rotation. After that, when the same signal is input between o and a this time, the motor 38 is connected because this o a is in contact.
Is rotated, and it stops at a regular position by half rotation. However, the valve is closed because of o-a.
Therefore, it is achieved by inputting the drainage signal again and opening the valve with OB. Assuming that the time required for half rotation is 4 seconds, it takes 12 seconds for 3 operations, but the time cannot be extended by starting only the draining operation during the end of washing. Also, even if it takes 12 seconds, there is no problem. In particular, the first signal for each of water supply and drainage depends on the state of the leaf, but there is no valve operation, and most of them only receive a signal, and not all 12 seconds are valve operation.

When it is really necessary, when the power failure during the so-called so-called motor rotation mentioned above stops when the power is turned off, for example, the valve opens halfway due to a drain signal and then stops, and the o-a contact is not closed. , It is a countermeasure for the trouble that it does not work at all even if the water supply signal is input. Therefore, in the microcomputer, at the first operation after the power is turned off, while confirming the position of the valve with this repeated signal, it is set to the normal position,
As long as the power is not turned off, the method of proceeding with the signal of drainage and the signal of water supply once from the next operation is also considered. By doing this, only the first time, it takes longer than the conventional method, but the operation It is possible to provide a drain valve without sound.
