Description

[Detailed Description of the Invention] Conventionally, in a single-tank fully automatic dehydrating washing machine, the number of revolutions of the rotor during washing and the number of revolutions of the inner tub during dehydration are different. The reduction mechanism is of a sequential assembly type, that is, the mechanism of one part of the reduction gear is independently attached and cannot be removed.

As a result, it is not possible to perform a preliminary meshing inspection of gears during manufacturing and assembly, and gear interference noise is discovered after the entire assembly has been completed, resulting in a large loss and inconvenience in the case of repairs. .

In other words, when repairing, there is no choice but to replace the entire transmission mechanism. Replacing only the gear part will not only cause the sealed oil to leak out and stain the floor, shorten the life of the gear due to a decrease in oil, but also cause problems during assembly. Similarly, gear meshing tests could not be conducted in advance, and gear interference noise could occur after complete repairs, which was extremely inconvenient.

The single-tank fully automatic washing machine of the present invention relates to an improvement in the structure of the speed reduction mechanism, and by improving the structure, the drawbacks of the conventional example are improved and productivity and repairability are improved. It is.

is formed.

Reference numeral 42 designates a gear case that also serves as a pulley, in which a hollow shaft 43 with a seat is fixed, and the hollow shaft 43 with a seat is rotatably arranged around the outer periphery of the different diameter portion 41 formed at the lower part of the dehydration relay shaft 38, and is prevented from being pulled out. It is locked by a ring 44.

45 is the outer periphery of the different diameter portion 41 of the dehydration relay shaft 38 and the hollow shaft 4 with a seat.
3. A backing 46 inserted between the large inner diameter portions is a gear fixed below the dewatering relay shaft 38, and passes through the washing relay shaft 47 in a freely rotatable manner.

Further, a washing gear 48 is fixedly installed below the washing relay shaft 47, and a columnar projection 49 having a square cross section is formed at the upper end.

Reference numeral 50 denotes a hollow shaft joint that is rotatably contained within the dehydration relay shaft 38, and the upper part fixes the lower end of the washing shaft 26 with a pin 51, and the lower part inserts and engages the upper end of the washing relay shaft 47 to perform washing. The shaft 26 and the washing relay shaft 47 are connected.

Reference numeral 52 designates a planetary gear integrally formed with gears having different numbers of teeth, and is rotatable on a pin 53 fixed to the gear case 42 that also serves as a pulley, and is internally incorporated in the gear case 42 that also serves as a pulley and meshes with the gear 46 and the washing gear 48. There is.

A gear cap 54 inserts and supports the lower end of the pin 53 and rotatably supports the lower end of the washing relay shaft 47 via a metal 55. The gear cap 54 covers the opening on the lowermost surface of the gear case 42 which also serves as a pulley. are integrated.

56 is a lubricating oil sealing ring housed in the gear case 42 that also serves as a pulley; 57 is a clutch spring inserted into the outer diameter of the dehydration relay shaft 38 and the outer diameter of the hollow shaft 43 with a seat, which has the same diameter as this outer diameter; Reference numeral 58 designates a clutch boss that includes a clutch spring 5T and locks one end of the clutch spring, and 59 designates a one-way rotating clutch claw provided on the switching lever 36, which is used for dewatering and washing together with the clutch spring 57, clutch boss 58, etc. It constitutes a clutch mechanism that switches between

With the above configuration, the gear case 42 that also serves as a pulley is rotatably provided on the dehydration relay shaft 38 with a pullout prevention ring 44, and this dehydration relay shaft 38 is connected to the brake wheel 28, and the dehydration relay shaft 38 is connected to the brake wheel 28, and the dehydration relay shaft 38 is The shaft 38 (consisting of parts internal to the pulley/gear case 42, etc.) can be removed as a unit by simply removing the dehydration relay shaft 38 from the brake wheel 28 by operating the mounting member 40'.

Next, the function will be explained. In FIG. 2, the brake lever 29 is in a stopped state in which the brake wheel 26 is strongly shaken in the washing and rinsing state, and the dewatering shaft 12 connected to the brake wheel 28 does not rotate.

Further, since the clutch boss 58 is stopped by a clutch pawl 59, the clutch spring 57 is also stopped in the same way.

Therefore, when the rotational force is transmitted from the transmission belt 20 to the gear case 42 that also serves as a pulley, the gear case 42 that also serves as a pulley
The planetary gear 52, which is rotatably provided on a pin 53 fixed to the pulley/gear case 42, engages with the gear 46 and the washing gear 48 and rotates around the gears 46, 48 while rotating.

At this time, the rotational force transmitted to the washing gear 48 rotates the rotary blade 3 provided at the upper end of the washing shaft 26 via the washing relay shaft 47 and the connecting shaft 50.

At this time, the diameter of the pulley 19 is = D1, and the pulley diameter of the gear case 42 that also serves as a pulley is: D2. Slip loss of transmission belt 20: LS, number of teeth of gear 46: zl, number of teeth of planetary gear 52 meshing with gear 46: z2. Number of teeth of washing gear 48: 24. Assuming that the number of teeth of the planetary gear 52 meshing with the washing gear 48 is 23, the washing rotation speed is reduced to the frost machine rotation speed xD1/D2 XLS XC1-z1xz3).

Z2 x z4 Next, during dewatering, when the switching lever 36 is pulled by a solenoid valve (not shown) and rotates around the shaft 37, the stopper 60 provided at the top of the switching lever 36 turns the roller bracket 34 and closes the brake lever. 29 and release the brake wheel 2B.

Furthermore, the clutch claw 59 provided at the bottom of the switching lever 36 is separated from the clutch boss 58 and is connected to the clutch spring 57.
connects the dewatering relay shaft 38 and the gear case 42 which also serves as a boob.

At this time, the planetary gear 52 does not rotate, and rotates at the same rotation while being engaged with the gear 46 and the washing gear 48.

Therefore, at this time, if the diameter of the pulley 19 = Dl, the pulley diameter of the gear case 42 (D2) and the slip loss of the transmission belt 20: Ls, then the rotational speed for dewatering is the motor rotational speed XD1/D2 XLS.

As is clear from the above-mentioned embodiments, the single-tank fully automatic washing machine of the present invention has a dehydration relay shaft of a reduction mechanism housed in a gear case that also serves as a pulley driven by an electric motor, which is attached to a brake wheel. Since the laundry relay shaft is engaged with the washing shaft, assembly is completed by simply attaching the dehydration relay shaft to the brake wheel, improving assembly efficiency and making it easy to replace gears that produce gear noise during process inspections. It is something that can be done.

Furthermore, since the speed reduction mechanism can be disassembled as a unit, there is no oil leakage during repairs, there is no need to turn the entire washing machine upside down, and gear engagement can be easily adjusted. It has a great effect.

Furthermore, the speed reduction device and clutch device are provided outside the metal case, and can be disassembled as a unit by removing the brake wheel and dewatering joint shaft.

In other words, the speed reduction device and the clutch device are easy to repair, and the speed reduction device is easy to repair.

The clutch device can be easily adjusted as a unit, and furthermore, since the metal case remains fixed, eccentricity does not occur.
