、18は排水ホーヌである。2. Description of the Related Art A conventional fully automatic washing machine has a structure as shown in FIG. In the figure, 1 is an outer box, and the upper part of this outer box 1 is covered by an upper frame 2. Furthermore, legs 3 are provided at the bottom of the outer box 1. An operation panel 4 housing a control unit is arranged behind the upper frame 2.
A central opening 5 is covered with a lid 5 so as to be openable and closable. On the other hand, inside the outer box 1, a water tank 8 is suspended by a rod 9 in a vibration-proof manner. The water receiver is in tank 8, which also serves as a washing and dehydrating tank (
A dehydration tank (hereinafter referred to as a dehydration tank) 1o is rotatably arranged, and a balancer 11 is attached to its upper part. Dehydration tank 10
Stirring blades 12 are disposed at the inner bottom of the stirring row 12, and the rotation of a motor 14 is transmitted to a belt 15 via a deceleration drive section 13. On the other hand, a safety switch 7 is provided in the operating spring L'4, and an operating lever 6 for operating the safety switch 7 extends downward, so that the water receiver is activated when the tank 8 swings around. 16 is a drain valve, 17 is a cock, and 18 is a drain horn.

であった。With the above configuration, a series of courses starting from washing is operated, but if the cloth is lopsided during washing, the tank 8 swings around and hits the outer box 1 in the water tray at the initial stage of dehydration. At this time, if the water tank 8 swings around a lot and it hits the outer box, the safety switch 7 will be activated and the water will be refilled, and the process of washing again and removing the cloth will start. It was something I could enter.
発明が解決しようとする課題

によってその動作点が変動してしまい、精度高く水受は
槽が外箱内面に衝突することを検知できないという課題
を有していた。Problems to be Solved by the Invention In the above configuration, the operating lever 6 of the safety switch 7 does not actually work because the water receiver is located between the tank 8 and the outer box 1 and the water receiver detects the whirling of the tank 8. In the case of the water receiver, the safety switch 7 sometimes operated even when the tank 8 did not touch the inner surface of the outer box 1. That is, the safety switch 7 operates when the operating lever 6 is pushed toward the outer box 1 side on the side of the water tank 8, and the pushing width exceeds a predetermined width. Due to variations in the parts and mounting position, the operating point fluctuates depending on the mounting position, and the highly accurate water receiver was unable to detect when the tank collided with the inner surface of the outer box.
本発明は上記課題に鑑み、槽の振れまわりによる衝突を
精度高く検知することを目的とする。In view of the above problems, it is an object of the present invention to detect collisions caused by whirling of a tank with high accuracy.

In some cases, the outer box or water receiver is equipped with a collision detection means for detecting the impact force colliding with the tank, and an abnormality determination means for inputting the signal of this collision detection means and outputting an abnormality signal, and the abnormality determination means is configured to detect the collision. When the impact force value from the detection means exceeds a predetermined value, an abnormality signal is output.

sends the strength at the time of collision to the pressure value input section 21 in the control section 24 as a signal. The abnormality determining means 22 determines whether the value input to the pressure value input section 211C exceeds a set value. The result determined by this abnormality determining means 22 is outputted to the output unit 2.
However, when the abnormality determination means 22 determines that the value exceeds the set value, the motor 14. Drain valve 16
It sends signals to electrical components such as Pressure value input section 21.
Abnormality determination means 22. The output section 23 constitutes a control section 24 .

移行する。The operation of the above configuration will be explained based on the flowchart of FIG. When dehydration is started, the output section 2 of the control section 24
From 3, (- cod 4) is output to the drain valve 16, and the dehydration information that also serves as the tip of the bulge begins to be passed down. At this time, if the cloth is uneven or the installation surface is slanted, the water receiver will be drained from the tank 8. Outer box 1
corresponds to The collision at this time is input from the pressure sensor 19 to the pressure value input section 21 as an electric signal by the collision detection means 20. If this input value is B, the abnormality determination means 22
It is determined whether B is larger than the set value A within the set value A. B
If it is above , the abnormality determining means 22 outputs a signal to cut the output from the output section 23, and the motor 14 and the drain valve 16 are stopped. After this, refill the water and
The process moves on to washing, loosening the fabric, and then moving on to dehydration again.
