す。2. Description of the Related Art For example, as shown in FIG. 7, a fully automatic washing machine of a one-tub type has a vibration isolator 2 in an outer box 1 installed on a bottom frame 8.
A water tub 3 is oscillatably supported via a water tank, and a washing / dehydrating tub 5 having rotary blades 4 at the bottom is rotatably disposed in the water tub 3. The water tub 3 is driven at the bottom. A mechanism portion 7 such as a motor 6 and a reduction mechanism such as a clutch and a gear is attached as a mechanism, and a top cover 9 is attached to an upper position of the water tank 3 on an upper portion of the outer box 1 and the top cover 9 is attached.
The lid 10 is attached to the lid so that it can be opened and closed. Reference numeral 11 in the figure denotes a water supply case communicating with the water supply port provided in the top cover 9.

装置２で吸収される。During the washing operation, the entire process of water supply, washing process, rinsing process and dewatering process proceeds automatically, but the rotor 4 rotates during the washing process, and the rotor 4 rotates during the dewatering process.
When the washing and dewatering tub 5 rotates at high speed, the vibration is transmitted to the water tub 3 and the water tub 3 swings, but some vibration is absorbed by the vibration isolator 2.

形、部品の破損などが発生するおそれがある。However, especially in the dehydration process, the washing and dehydrating tank 5
If the clothes are biased inside, the washing / dehydrating tub 5 shakes greatly, and this vibration is transmitted to the water tub 3, and the water tub 3 also vibrates greatly. When such a large abnormal vibration occurs, the water tank 3 may hit the outer casing 1, and abnormal noise due to vibration, deformation of the outer casing 1, damage to parts, and the like may occur.

配設している。Therefore, when abnormal vibration occurs, it is detected to stop the dehydration operation, and an unbalance detection device is provided for that purpose. In the conventional unbalance detecting device, for example, a detection lever is used as a pressing member that is pressed when the water tank 3 is displaced by vibration in a substantially triangular space formed inside the rear corner portion of the outer box 1. It is positioned and attached to the top cover 9 or the like by a mounting member, and a detection switch that operates by the displacement of the lever is also arranged inside the top cover 9 by the mounting member.

ものが必要になる。As described above, the conventional unbalance detecting device is composed of the detecting lever, the detecting switch, and the members for attaching the lever and the detecting switch to the top cover, respectively. The number of points is large, and as a result, the number of assembling steps is also large. In addition, a lead wire for inputting a signal from the detection switch to the control device is also required, and since the control device is usually arranged at the front plate 13 of the outer box of the washing machine, the length of the lead wire is long. You also need long ones.
【００１０】また、検知スイッチはレバーにより１回で

たがい、アンバランスが検出される回数は２回、３回と
増加する。Further, since the detection switch is turned on even if it is pressed by the lever even once, the washing / dehydrating tub is stopped just by turning on the detection switch once by one swing of the water tub. Therefore, even if the amount of unbalance is small and the washing / dehydrating tub does not need to be stopped for a slight displacement, the washing / dehydrating tub may stop, which may hinder the smooth progress of the washing operation. is there. By the way, as shown in the graph of FIG. 6, when the amount of imbalance (the amount of unevenness of laundry in the washing and dehydrating tub) is small, the imbalance is detected only once, but the imbalance is small. As the amount increases, the number of times imbalance is detected increases to 2 or 3.

短くてすむ。In order to achieve the above-mentioned object, the present invention firstly hangs a water tank swingably in an outer box,
An unbalance detecting device arranged between the outer box and the water tub of a washing machine in which a washing / dehydrating tub having a rotary wing at the bottom is rotatably arranged in the water tub. Was attached to the case of the power supply unit arranged in the outer box. This eliminates the need for a member for attaching the unbalance detecting device to the top cover as in the conventional case, and the number of parts and the number of assembling steps can be reduced. Further, the lead wire connecting the unbalance detection device and the control device can be short.

には洗濯兼脱水槽の回転を停止させずにすむ。Secondly, the unbalance detecting device is composed of a lever that is displaced by the swing of the water tank and a sensor that detects the displacement of the lever, so that even if the sensor detects the lever displacement, the detection operation is performed. Since it can be separated from the rotation stopping operation of the washing / dehydrating tub, it is not necessary to stop the rotation of the washing / dehydrating tub when the amount of unbalance is small.

となる。Thirdly, since the sensor is composed of a light emitting element and a light receiving element, it is possible to detect the number of lever displacements of the sensor, and the washing / dehydrating tub can be stopped based on this number of times. Control corresponding to the balance amount becomes possible.
【００１５】第４に、外箱内に水槽を搖動自在に吊支

不都合を解消できる。Fourthly, the outer box of a washing machine in which a water tub is slidably suspended in the outer box and a washing / dehydrating tub having rotary blades at the bottom is rotatably disposed in the water tub. An unbalance detection device including a lever that is displaced by the swing of the water tank and a sensor that detects the displacement of the lever is provided between the water tank and the water tank, and the unbalance amount in the washing / dehydrating tank and the displacement detection by the sensor are arranged. The rotation of the washing / dehydrating tub is stopped according to the amount of unbalance because it is determined whether or not an unbalance that stops the rotation of the washing / dehydrating tub occurs. The inconvenience of stopping the rotation can be eliminated.
【００１６】第５に、前記センサでの変位検出は、検出

ス発生かを判断することにより、検出回数が多く、確実
にアンバランスが発生している場合にみ洗濯兼脱水槽の
回転を停止できるから、現状に適した対応ができる。Fifth, in the displacement detection by the sensor, the number of times of detection is large and the unbalance is surely generated by judging whether or not an imbalance occurs to stop the rotation of the washing / dehydrating tub based on the number of times of detection. The rotation of the washing and dehydrating tub can be stopped only when there is, so it is possible to respond to the current situation.

きる。Sixth, in the displacement detection by the sensor, the time during which the lever is displaced is detected, and it is determined by the length of this time whether or not an imbalance occurs in which the rotation of the washing / dehydrating tub is stopped. Since the rotation of the washing / dehydrating tub can be stopped only when the lever is displaced for a long period of time and the imbalance is surely generated, it is possible to cope with the current situation.

And a sensor 15 for detecting the displacement of the lever 14. The sensor 15 is, for example, a photointerrupter formed by a light emitting element 15a and a light receiving element 15b. The light shielding portion 1 of the lever 14 is provided in the gap formed between the light receiving elements 15b.
4a is displaceably arranged. The light shielding portion 14a is, for example, formed by a protruding piece that horizontally projects integrally from the back surface of the lever body.

ら抜け出る。Next, the operation will be described. In a normal state, the light shielding portion 14a of the lever 14 is located between the light emitting element 15a and the light receiving element 15b, and the light emitting element 15a to the light receiving element 15 are provided.
The light emitted in the direction of b is blocked and is not transmitted to the light receiving element 15b. When the clothes in the washing / dehydrating tub 5 are biased during the dehydration process and the washing / dehydrating tub 5 swings significantly, the vibration is transmitted to the water tub 3 and the water tub 3 also vibrates. As a result, the water tank 3 swings in the direction of the outer box 1 and comes into contact with the lever 14, and when the lever 14 is pressed, the lever 14 rotates outward with the attachment portion to the unit case 16 as a fulcrum,
The light shielding portion 14a is pulled out from between the light emitting element 15a and the light receiving element 15b.
【００２２】その結果、発光素子１５ａから発せられて

からの光を遮断する。As a result, the light emitted from the light emitting element 15a is detected by the light receiving element 15b, and the sensor 15 detects the displacement of the lever 14. In this case, when the shaking of the water tank 3 subsides, the light-shielding portion 14a of the lever 14 is turned on again by the light-emitting element 1.
5a and the light receiving element 15b, and the light emitting element 15a
Block the light from.

脱水槽５の回転を停止せずにすむ。The number of times the light-shielding portion 14a of the lever 14 comes out between the light emitting element 15a and the light receiving element 15b is
As can be judged from the graph shown in FIG. 6, the larger the amount of imbalance in the washing / dehydrating tub 5, the larger the amount of imbalance. Therefore, this number of times is detected, and only when the amount of imbalance is large, washing is performed by the output of the controller. The rotation of the dewatering tank 5 is stopped. Therefore, the rotation of the washing / dehydrating tub 5 need not be unnecessarily stopped when the unbalance amount is small.

を停止することができる。Further, since the light shielding portion 14a of the lever 14 is displaced by moving between the light emitting element 15a and the light receiving element 15b, the displacement amount, that is, the unbalance amount can be determined by detecting the displacement amount. The rotation of the washing / dehydrating tub 5 can be stopped only when the unbalance amount is large based on the amount.

不都合を解消できる。Fourthly, the outer box of a washing machine in which a water tub is slidably suspended in the outer box and a washing / dehydrating tub having rotary blades at the bottom is rotatably disposed in the water tub. An unbalance detection device including a lever that is displaced by the swing of the water tank and a sensor that detects the displacement of the lever is provided between the water tank and the water tank, and the unbalance amount in the washing / dehydrating tank and the displacement detection by the sensor are arranged. The rotation of the washing / dehydrating tub is stopped according to the amount of unbalance because it is determined whether or not an unbalance that stops the rotation of the washing / dehydrating tub occurs. The inconvenience of stopping the rotation can be eliminated.

回転を停止できるから、現状に適した対応ができる。Fifth, in the displacement detection by the sensor, the number of times of detection is large and the unbalance is surely generated by determining whether or not an imbalance occurs which stops the rotation of the washing / dehydrating tub based on the number of times of detection. The rotation of the washing and dehydrating tub can be stopped only when there is, so it is possible to respond to the current situation.

きる。Sixth, in the displacement detection by the sensor, the time during which the lever is displaced is detected, and it is determined by the length of this time whether or not an imbalance occurs in which the rotation of the washing / dehydrating tub is stopped. Since the rotation of the washing / dehydrating tub can be stopped only when the lever is displaced for a long period of time and the imbalance is surely generated, it is possible to cope with the current situation.
