This is related to the improvement of.

Conventional Structure and Problems The structure of this type of conventional dehydration washing machine with drain pump is as shown in Figures 1, 2 and 3, in which 1 is the main body, 2 is a dehydration/washing tub with multiple dehydration holes 3, and rotor 4 is disposed at the bottom. 5 is a water receiving tub with a lid 6 on top, which is fixed to a mounting base 7. Meanwhile, the bottom of the water receiving tub 5 has drainage holes 8, and the drainage holes 8
is connected to the suction side of a drainage pump 9 fixed to the main body 1. Numeral 10 denotes a seal body, and numeral 11 denotes a ball bearing which is press-fitted into a housing 12 and supports a spin-drying shaft 15 having a top end fixed to the spin-drying/washing tub 2 together with a ball bearing 14 press-fitted into a case 13. The housing 12 and the case 13 are both attached to a mounting board 7.

A rotary blade 4 is installed coaxially with the dewatering shaft 15 and is provided at the upper end.
There is a washing shaft 16 arranged with
Clutch springs (not shown) are wound around and opposed to each other. Reference numeral 18 designates a clutch boss that encloses a clutch spring, engages a bent portion of the drive side winding end of the clutch spring, and has a blade portion on the outer periphery. 19 is a motor, and the motor pulley 20 fixed to this is,
Rotation is transmitted to the pulley 17 via the belt 21.

Further, 22 is a brake body containing a brake wheel 23 fixed to the dewatering shaft 15, and 24 is a movable part. 25 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 solenoid that interlocks the brake lever 26 and the clutch lever 27 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 29 of the clutch lever 27
engages with the clutch boss 18. When the motor 19 is driven in this state, the drive boss (not shown) will
Washing is performed by sliding on the clutch spring and rotating only the washing shaft 16.

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 shaft 15 becomes free, the pawl 29 is separated 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 the clutch spring to perform dewatering.

Next, the structure near the solenoid 30 will be explained. 34 is 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. A retaining pin 39 is provided thereon.

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

In this way, since the connecting fitting 35 keeps the movable piece 34 side of the solenoid 30 and the clutch lever 27 and brake lever 26 sides fixed,
Due to misalignment of the case 13 to the mounting board 11 and misalignment of the solenoid 30 to the bottom of the water tank 5,
Due to the large size, there was a problem that the solenoid 30 did not attract at 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 as in a natural drainage type, along with the suction,
There is no need to suction the drain. 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 pot, the position of the end portion becomes difficult to determine, which in turn adversely affects the operation of the clutch lever 27 and brake lever 26.

Purpose of the invention This invention solves problems such as the operation lever of a dehydrating washing machine with a drain pump being different from that of a natural drainage type washing machine, and furthermore, the stroke of the solenoid cannot be adjusted. Disassembly,
Adjustments, etc. are at the same level as natural drainage type dehydrating washing machines,
The purpose of the present invention is to provide a dehydrating washing machine with a drain pump of stable quality.
