Description

[Detailed description of the invention] The present invention relates to an agitation-type dehydrating washing machine equipped with a washing and dehydrating tank in which an agitating blade base with a plurality of agitating blades is installed in the center, and is more effective in the rinsing process. The purpose of this is to enable easy rinsing.

Conventional rinsing methods for this type of agitation-type dehydrating washing machine include (a) a rinsing method in which the cycle of draining the washing liquid → supplying clean water → stirring → draining is repeated to gradually dilute the washing liquid; and (b) ) An overflow type was used in which clean water was supplied from the top of the washing and spin-drying tank and the washing liquid was discharged from the overflow port provided at the top of the outer tank, but the former had extremely poor rinsing effect; It is necessary to repeat the water supply/drainage cycle many times, and in the latter case, the supplied fresh water tends to flow directly into the overflow port, resulting in problems such as a poor rinsing effect.

The present invention has been made to solve the above-mentioned conventional problems, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

24 is a shock absorbing device incorporating a spring and a damping device (both not shown), 25 is a lower hemisphere, and 26 is an upper hemisphere, through which a hanging rod 27 is inserted together with the lower hemisphere 25; The outer tank 4 is suspended and supported within the main body 1.

Reference numeral 28 denotes a fresh water supply port having a valve 29 and a magnet 30 in the pipe line, and the fresh water discharged from the fresh water supply port 28 is conveniently positioned to fall into the fresh water intake port 12 at the upper end of the stirring blade base 9. ing.

Reference numeral 31 indicates a balance weight of an appropriate type fixed to the opening at the upper end of the washing/drying tub 2, and reference numeral 32 indicates an installation leg attached to the outer bottom of the main body 1.

Reference numeral 34 is another drain hose which is led out from a drain port 35 at the bottom of the outer tank 4, and whose tip is communicated with the drain port 8, and an ice drain valve 36 that is opened only when draining water is connected in the middle.

The operation in the above configuration will be explained.

First, after the washing process is completed, when the rinsing process is turned on manually or automatically, the motor 17 is energized and the power of this motor 17 is transferred to the motor pulley 19. ■Belt 2
0 to the stirring blade pulley 21, and then this power gives an oscillating motion to the stirring shaft 14 via the washing/dehydration switching clutch and crank mechanism built into the dehydration bearing 16.

Due to this rocking movement, the stirring blade base 9 and the stirring blades 13 fixed to the stirring blade shaft 14 also perform a similar rocking movement, and therefore, the clothes 33 in the washing and dehydrating tank 2 are moved. At the same time, the magnet 30
Since the valve 29 is also energized to suck the valve 29, fresh water for rinsing also flows out from the fresh water supply port 28.

The fresh water for rinsing that flowed out at this time is from the fresh water supply port 28.
Since the position is convenient, the water falls smoothly into the fresh water intake port 12 at the upper end of the stirring blade base 9 as shown by the arrow.

In addition, the fresh water for rinsing taken in from the fresh water intake port 12 is fed to a large number of small holes 10 provided below the stirring blade base 9.
The rinsing water is pushed out into the washing and dehydration tank 2, and this pushed out rinsing water effectively passes between the clothes 33 and dilutes the detergent concentration.

Here, the fresh water for rinsing taken in from the fresh water intake port 12 is pushed out from the small hole 10 by its own gravity, and the water near the small hole 10 is pushed out from the small hole 10 by the swinging movement of the stirring blade 13. Because it is pushed to the outside of 9, the small hole 1
The vicinity of 0 represents a negative pressure state, and therefore, the rinse water flows into the washing and dehydrating tank 2 more efficiently.

In other words, it can be said that the swinging motion of the stirring blades 13 produces a kind of pumping action.

On the other hand, since fresh water for rinsing enters from the bottom of the washing and dewatering tank 2, the high concentration washing liquid at the top overflows from the overflow port 6 provided at the top of the outer tank 4, and then from the drain hose. 7 and then drained out of the washing machine from a drain port 8.

In this way, the clean water for rinsing can sufficiently pass between the clothes 33 before being discharged from the overflow port 6, and the washing concentration can be diluted, so that the clean water effectively contributes to the rinsing action without any waste. can be done.

Note that the water flow generated by the rocking motion of the stirring blade base 9 and the stirring blades 13 passes through the dehydration hole 3 of the washing and dehydration tank 2, and a weak water flow is generated.

Also, since a water flow is generated due to the outflow of rinsing water to the overflow port 6, the detergent concentration of the washing water existing between the bottom of the washing and dehydrating tank 2 and the bottom of the outer tub 4 also decreases over time during the rinsing process. Furthermore, the detergent concentration in this part is
Since it is relatively low compared to the inside, it does not interfere with the overall rinsing.

As described above, according to the present invention, the stirring blade base is configured in a hollow annular shape with an open upper end, and the lower part of the stirring blade base has a large number of small holes that communicate the inside of the base with the inside of the washing/dehydration tank. At least during rinsing, water is injected from the upper end opening of the agitation blade base. Therefore, during rinsing, fresh water enters the interior of the washing/dehydration tank through the numerous small holes and the agitation blades Combined with the stirring action of The clean water overflows from the overflow port through the hole, contributing to the rinsing action without being wasted, making it possible to perform an effective rinsing action, and therefore the amount of water used for rinsing can be greatly reduced. In addition, since the rinsing time is shortened, it is extremely effective from the standpoint of resource and energy conservation.Moreover, by shortening the rinsing time, there is less damage to clothes. Various practical effects can be achieved with a simple configuration.
