Further, 22 is a brake body containing a brake wheel 23 fixed to the dehydration shaft 15, and 24 is a movable part 2.
5 is a movable piece that is pivotally supported by the case 13 and connected to the movable part 24; 26 is a brake lever that comes into contact with the movable piece 25; has been done.
Reference numeral 29 denotes a pawl disposed at the other end of the clutch lever 27, which engages with the vane portion of the clutch boss 18.
30 is a brake lever 26 and a clutch lever 2
This is a solenoid that operates 7 in conjunction with each other, and is fixed to the bottom of the water tank 5.

The mounting board 7 is suspended and supported on the upper edge of the main body 1 by a support rod 32 via a buffer body 31. Reference numeral 33 denotes legs arranged at the bottom of the main body.

Here, the washing, draining, and dewatering operations are changed by the operation of the solenoid 30. That is, when the solenoid 30 is not energized, the brake wheel 23 is fixed and the pawl 2 of the clutch lever 27 is closed.
9 engages with the clutch boss 18. When the motor 19 is driven in this state, the drive boss (not shown)
The washing machine slides against the clutch spring and rotates only the washing shaft 16 to perform washing.

Next, when the solenoid 30 is energized and the clutch lever 27 and brake lever 26 are interlocked, the brake body 22 is separated from the brake wheel 23.
The dewatering tank 15 becomes free, the pawl 29 separates from the clutch boss 18, the clutch spring is wound around the drive boss, and the drain pump 9 is also energized at the same time, so that water is drained. When the motor 19 is driven, the dewatering/washing tub 2 rotates via a clutch spring to perform dewatering.

Next, the structure near the solenoid 30 will be explained. Reference numeral 34 denotes a movable piece of the solenoid 30, which is connected to the connecting fitting 35 by a split pin 36.
A clutch lever 27, a brake lever 26, and an insulating tube 37 covering these are mounted inside the substantially U-shaped end of the connecting fitting 35, and a pivot shaft 38 is inserted into a through hole passing through each member. established,
A retaining pin 39 is attached to this.

Further, a tension spring 41 is interposed between the spring fitting 40 fixed to the bottom of the water tank 5 and the split pin 36 so as to support the movable piece 34 of the solenoid 30.

In this way, the connecting fitting 35 fixedly determines the movable piece 34 side of the solenoid 30 and the clutch lever 27 and brake lever 26 sides. Due to the misalignment of the attachment to the bottom of 5, the A dimension became large, and there was a problem that the solenoid 30 did not attract with a constant voltage.

In addition, in a drain pump type dehydrating washing machine, the clutch lever 27 and the brake lever 26 may be suctioned by the suction operation of the solenoid 30, and like a natural drainage type, the drain cot is suctioned along with the suction. do not have to. Therefore, there is no need to connect a drainage pot to the end of the connecting fitting 35 on the opposite side from the solenoid 30. However, by not connecting the drain socket, the position of the end becomes difficult to determine, which not only adversely affects the operation of the clutch lever 27 and brake lever 26, but also makes it difficult to absorb the shock when the solenoid 30 is opened. This is a difficult configuration, and as a result, the sound when the solenoid 30 is opened is loud.

Purpose of the Invention The present invention solves problems such as the operating lever of a dehydrating washing machine with a drain pump being different from that of a self-draining washing machine, and furthermore, the stroke of the solenoid cannot be adjusted. The purpose of this invention is to provide a dehydrating washing machine with a drain pump that has stable quality and has the same level of adjustment, etc. as a natural drainage type dehydrating washing machine.

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides a connecting fitting that connects one end to a solenoid, restricts contact with the brake lever and clutch lever and operates in conjunction with the brake lever and clutch lever, and provides the other end of the connecting fitting. A flat part is provided in the water receiving tank, and a slider fixing fitting equipped with a slider that is slidably inserted into the flat part is fixed to the water receiving tank.
