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

An 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 denotes a water reservoir mainly for containing synthetic detergent, and the water reservoir 28 consists of a detergent reservoir 29 for containing detergent, and a mixing chamber 31 for mixing detergent and water and having a number of holes 30 at the bottom.

32 is a handle, and 33 is a partition plate that partitions the detergent receiver 29 and the mixing chamber 31, and the partition plate 33 is formed lower than the height of its surroundings.

Reference numeral 34 denotes a water injection case that houses the water injection receiver 28, and has a water injection port 35 protruding from the top surface to be connected to the water injection hose 10, and a plurality of ribs 36 provided on the inner bottom surface to form a gap between the ribs 36 and 36. 37 is formed.

Reference numeral 38 denotes a screw hole through which the screw 9 is inserted, and the water injection case 34, that is, the water injection device 8, is fixed to the panel 4 with the screw 9.

Therefore, the water injection receiver 28 has a rib 3 inside the water injection case 34.
It is inserted while resting on the detergent tray 29.
When supplying detergent, grasp the handle 32 of the water injection receiver 28 on one side opening side of the water injection case 34, pull out the water injection receiver 28, pour detergent into the detergent receiver 29, and push the water injection receiver 28 into the water injection case 34. Good.

In this state, when the water supply valve 7 is opened and tap water is poured into the detergent receiver 29 from the water inlet 35, the water and detergent in the detergent receiver 29 overflow from the partition plate 33 and enter the mixing chamber 31. The water and detergent are stirred, dispersed, and flowed out through the holes 30, and this mixed water flows through the gap 37 between the lower surface of the water supply receiver 28 and the inner bottom surface of the water injection case 34, is dispersed by the ribs 36, and flows into the water injection case 34. It is put into the washing tub 11 from the opening side.

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. This is done by pouring water into it.

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 is often added, and rinsing is insufficient, or there are many bubbles during dehydration, which often act as resistance to the dehydration rotation and cause 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, for detergents, which are the most expensive, the savings are significant.

Detergent dispensing devices have been considered in the past, but they have a complicated structure, and because the detergent is stored inside the device, it absorbs moisture and gets clogged in 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 29 for receiving the detergent as described above, and this volume is set in relation to the amount of detergent required for one wash. Pour one cup into the tray 29, or half a cup when there is little dirt or a small amount of laundry.

In the case of concentrated detergents that have been used recently, by making connections and clarifying how to use them, such as reducing the amount by half of the conventional amount, 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.
After washing, it may remain undissolved and the cleaning effect will deteriorate.

Normally, before washing, you should add detergent to just water and stir well to dissolve the detergent completely before putting in the laundry, but in reality, in many cases, the laundry and detergent are added and then water is poured into the washing machine. Problems like this occur.

In order to solve this problem, the present invention first makes it possible to measure the amount of detergent in the detergent receiver 29, adds water to the detergent from the water inlet 35 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 water into the washing tub 11 from the feeding device, the water flow is not concentrated from one hole 30, but is designed so that the water flow spreads horizontally and disperses as much as possible.
This increases the effectiveness of dispersion.

As described above, this simple device is easy to operate and understand, saves detergent by measuring it, and quickly achieves the cleaning effect by dispersing the detergent.

In addition, when water is poured for rinsing, clean water is poured into the detergent receiver 29 because detergent has been poured into the detergent receiver 29 from the previous washing and there is no remaining detergent, 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 since the water injection receiver has a detergent receiver into which the detergent is placed and a mixing chamber, the detergent and water are easy to mix and are dispersed from the mixing chamber. It is easy to flow, and since it flows out through a large number of holes, the flow spreads horizontally and is reliably dispersed.

Also, since the partition plate between the detergent receiver and the mixing chamber is set low, the water and detergent from the water inlet reliably overflow into the mixing chamber and mix together.

This method of overflowing the detergent tray was adopted because, for example, when pouring out from the hole at the bottom, detergent absorbs water and becomes sticky, clogging the hole and preventing proper drainage. The company adopted a method that allows the water to flow through the air.

In addition, when water is poured during rinsing, which does not require the addition of detergent, the water enters the mixing chamber from the detergent receiver and is injected into the washing tub without any detergent, and there is no particular problem with the flow of water, and only the water is dispersed and flows into the washing tub. is supplied to

Also, since the water injection receiver can be removed from the water injection case, the interior can be easily cleaned.
