A bearing sleeve 19 for holding a shaft 18 connected to the washing tub 11 is fixed to the lower end of the outer tub 16.

The inner shaft 18 is hollow and has a wing shaft 20 connected to the rotor 14 inside.
is held.

A motor 21 is attached to the lower end of the outer tank 16 and drives a pulley 23 via a belt 22.

The pulley 23 rotates the washing tub 11 through the shaft 18 and the rotary blade 14 through the blade shaft 20 by switching a clutch built in the bearing sleeve 19 to perform dewatering, washing, and rinsing.

A drain hose 24 is connected to a drain port 25 provided at the bottom of the outer tank 16, and is connected to an external hose 27 via a cock 26.

The outer tank 16 (not shown) is elastically suspended from the four corners of the main body 1.

Next, details of the detergent injection device will be explained based on FIGS. 2 to 5.

Reference numeral 28 is a detergent receiver mainly for storing synthetic detergent, and a handle 29 is integrally provided.

Reference numeral 30 denotes a water injection case that houses the detergent receiver 28, and has a water injection port 31 protruding from the top surface that connects to the water injection hose 10, and a plurality of ribs 32, 33 provided on the inner bottom surface and the back surface. Gaps 34 and 35 are formed between 32, 33, and 33.

36 is a screw hole through which the screw 9 is inserted, and the water injection case 30, that is, the water injection device 8 is fixed to the panel 4 by the screw 9.

Therefore, the detergent receiver 28 is inserted into the water injection case 30 while resting on the rib 32.
When supplying detergent to the water filling case 8, grasp the handle 29 of the detergent receiver 28 on one side opening side of the water injection case 30, pull out the detergent receiver 28, pour detergent into the detergent receiver 28, and push the detergent receiver 28 into the water injection case 30. Good.

In this state, when the water supply valve 7 is opened and tap water is poured into the detergent receiver 28 from the water inlet 31, the water and detergent in the detergent receiver 28 are mixed, and the rear plate 37 of the detergent receiver 28 is 1, the mixed water overflows from the upper end of the rear plate 37, passes through the gaps 34 and 35, is dispersed by the ribs 32 and 33, and is introduced into the washing tub 11 through the opening of the water pouring case 30.

The handle 29 can be positioned above the upper end of the opening of the water injection case 30 as shown in FIG.
Water and detergent in the handle 8 can be prevented from flowing out from the upper end of the handle 29.

By the way, automatic synthetic detergent dosing devices have been known for some time, and this device performs a preliminary wash with just water before adding detergent and washing, and then automatically adds water to the detergent that was initially added. It is something that is injected and thrown in.

For this reason, a water injection device for washing and rinsing and a detergent injection device for pre-washing are provided separately.

This is provided separately for the purpose of adding detergent during washing.

However, in the present invention, detergent is added at the beginning of washing,
There is a special feature in the way the detergent is added.

Generally, washing with a washing machine requires water, detergent, and electricity, but among these, detergent is the most expensive item per use.

Moreover, too little detergent will not be effective, and too much detergent will not improve the effect.

It is necessary to put in an appropriate amount. However, in reality, too much water is often added, rinsing is insufficient, and there are many bubbles during spin-drying, which often creates resistance to the spin-dry rotation and causes problems.

In this way, adding too much detergent has no effect, but rather causes problems during rinsing and dehydration, which is an economic loss.

Therefore, it is possible to save detergent if the appropriate amount is added.

Moreover, the savings are significant for detergents, which are the most expensive.

A device for dispensing detergent has been considered in the past, but it has a complicated structure, and detergent has to be stocked inside the device (which absorbs moisture and clogs the holes), so there are few devices that are currently in practical use.

Therefore, the detergent dispenser of the present invention is provided with the detergent receiver 28 for receiving the detergent as described above, and the volume is set in relation to the amount of detergent required for one wash. Add one cup every 28 days, or half a cup when the laundry is lightly soiled or the amount of laundry is small.

In the case of concentrated detergents that have been used recently, by making the amount relevant, such as halving the amount of conventional detergents, and clarifying the usage method, it is possible to prevent the use of too much detergent and save money.

Furthermore, the structure is extremely simple, easy to understand, and anyone can operate it.

Next, there is a method of mixing detergent and water and dispersing it.
Conventionally, when you pour detergent in a concentrated manner, such as by scooping it into a cup, if the detergent gets caught up in the laundry before it dissolves due to the rotation of the washing machine, it becomes difficult to dissolve in the water.
Even after washing, it may remain undissolved and the cleaning effect will be poor.

Normally, it is okay to add detergent to just water before washing (you should stir the detergent completely before adding the laundry, but in reality, there are cases where you add the laundry and detergent first and then pour water. Many (, problems like the above occur.

In order to solve this problem, the present invention first makes it possible to measure the amount of detergent in the detergent receiver 28, adds water to the detergent from the water inlet 31 in the dosing device, mixes it, and disperses it together with the water. 11.

Therefore, according to the detergent dispensing device of the present invention, since the detergent is dispensed together with water, the detergent does not accumulate in one place in the washing tub 11, but is easily dispersed and dissolved in water, and does not remain in the form of detergent. .

Furthermore, when pouring into the washing tub 11 from the charging device, the water flow is not concentrated from one place, but is designed to spread as horizontally as possible and flow in a dispersed manner, thereby enhancing the dispersion effect.

This simple device is easy to operate and understand, saves detergent by measuring it, and quickly achieves cleaning effects by dispersing the detergent.

In addition, clean water is poured into the detergent receiver 28 for rinsing because there is no detergent left in the detergent receiver 28 from the previous washing, and water can be poured without any special operation.

The detergent injection device of the washing machine of the present invention can be implemented as described above, and the water supplied from the water inlet of the water injection case into the detergent receiver mixes with the detergent inside the detergent receiver.
This mixed water overflows from the upper end of the rear plate of the detergent receiver and is reliably injected into the washing tub through the gap between the water injection case and the detergent receiver.

Further, since the detergent receiver can be removed from the water pouring case, detergent can be easily supplied to the detergent receiver, and the interior can also be cleaned easily.
