Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fully automatic washing machine used in general households.

Conventional Structure and Problems Conventionally, this type of fully automatic washing machine, as shown in FIG. 2, an outer box main body 4 containing the water receiving tank 3 and the washing/dehydrating tank 2, and a top plate installed on the upper surface of the outer box main body 4 and having a laundry input port 5. 6
and a water inlet 9 that is attached to the top plate 6 and communicates with the water supply valve 7 through a hose 8. It is arranged on the upper surface of the washing wing 1 provided approximately at the center of the inner bottom of the dehydration tank 2. However, in this configuration, when water is injected from the water inlet 9, since the injected water directly hits the washing blade 1, the water not only scatters around, but also
In this case, when the lid 10 of the laundry input port 5 is opened, water may splash out from the laundry input port 5 and wet the installation floor. In addition, when moving to the rinsing process after washing, it is common to perform a dehydration process after washing in order to improve the rinsing efficiency.
Immediately after the spin-drying process is completed, water is injected for rinsing, but in this case, water is injected before the washing/spin-drying tank 2 has completely stopped, so this water is injected into the washing/spin-drying tank that is still rotating. 2, and as a result, there was a risk that the water would splash around and wet the installation floor as described above.

Furthermore, after spin-drying, the laundry clings to the inner wall of the washing/spin-drying tub 2, causing
Since there is no laundry in the central part of
This injected water does not directly come into contact with the laundry, and once the water has accumulated in the washing/spinner tank 2, the laundry becomes immersed in water. , the rinsing efficiency was reduced.

Purpose of the invention This invention solves the above-mentioned conventional problems.
The purpose is to prevent water from splattering during water injection and to improve rinsing efficiency.

Structure of the invention In order to achieve the above object, the present invention has a structure in which water is injected from a water inlet into the washing and dehydrating tank by positioning it between the outer periphery of the washing blade and the inner wall of the washing and dehydrating tank. By configuring the washing machine so that water is poured in and using the shower method for water flow when water is poured, the water injected from the water injection hole will not directly hit the top surface of the washing blade, so there will be no chance of the water being sprayed. Moreover, even if the laundry sticks to the inner wall of the washing/spinner tub after spin-drying before the rinsing process, the water injected from the water inlet will flow between the outer periphery of the washing blade and the inner wall of the washing/spinner tub. Since the shower system is located at a certain location and is reliable, the injected water is splashed onto the laundry, and as a result, rinsing can be performed quickly, and rinsing efficiency can be improved. In addition, even if the water inlet is approximately L-shaped, by placing a filter at the bend of the water inlet, turbulence that occurs at the bend can be suppressed and the final shower water injection can be performed reliably. It can be carried out.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Note that in FIGS. 2 and 3, the same parts as in FIG. 1 shown in the conventional example are given the same numbers, and only the points that are different from FIG. 1 will be explained. That is, as shown in FIGS. 2 and 3, in one embodiment of the present invention, the opening end 9a of the approximately L-shaped water inlet 9 is connected to the inner wall surface of the washing blade 1 and the washing/drying tub 2. Water inlet cap 11 facing the middle of
is provided at an angle, and a plurality of through holes 13 are provided in this water injection cap 11 . Water injection cap 11
is fixed so as to cover the opening end 9a of the water inlet 9. A filter 15 made of a transparent non-woven fabric is built into the bent portion of the water inlet 9, and a rib 14 protrudes from the water inlet 11 so as to have a gap S at the bottom of the filter 15. It is held fixed.

With the above configuration, the water injected from the water supply valve 7 through the hose 8 is once weakened in flow velocity by the filter 15 inside the water inlet 9 to suppress the occurrence of turbulence at the bend, and after passing through. It is collected in the gap S at the bottom of the filter 15. Thereafter, water is injected from the through hole 13 of the water inlet 11 that covers the open end 9a. In this case, since a plurality of through holes 13 are provided, the water injection state is a shower water injection state. Furthermore, since the water injection spout 11 is arranged at an angle so as to face the middle between the washing blade 1 and the inner wall of the washing/dehydrating tub 2, the shower water is injected without directly hitting the washing blade 1. After spin-drying, the laundry 12 is evenly and uniformly poured onto the upper part of the washing/spin-drying tub 2 that is stuck to the inner wall.

Further, the filter 15 is held and fixed inside the water inlet 9, but if the filter 15 and the through hole 13 of the water inlet 11 are in contact with each other, even if the flow rate of water is weakened by the filter 15, the permeable portion of the filter 15 Because of the turbulent flow occurring in the through hole 13, the water is pulled toward each other when flowing out of the through hole 13.
3, it was not possible to inject water consistently, and the shower water flowed down all at once. However, a gap S was provided between this filter 15 and the through hole 13 of the water inlet 11 to prevent them from coming into contact with each other. if,
Water that has passed through the filter 15 once accumulates in the gap S, then passes through the through hole 13 and flows down.
In this state, the turbulent flow when passing through the filter 15 is eliminated, and the water flowing out is not attracted to each other, so that a constant shower water injection is performed.

By injecting water from the shower at a constant rate or by injecting water between the washing blade 1 and the inner wall of the washing/dehydrating tub 2 in this way, the injected water no longer hits the upper surface of the washing blade 1 as in the past, and the water injection The shower water injection eliminates splashing and as a result, water splashing can be reliably prevented. Furthermore, even if the laundry 12 sticks to the inner wall of the washing/spinner tub 2 as shown in FIG.
When water is injected during the next rinsing process, the water injected from the water inlet 9 directly splashes on the laundry 12 stuck to the inner wall of the washing and dehydrating tub 2, and also sprays water uniformly over a wide area for shower water injection. laundry 1
The rinsing step 2 can be done quickly, and as a result,
This allows efficient rinsing. Furthermore, even if water is injected in the next rinsing process after the spin-drying is completed and the rotation of the washing and spin-drying tub 2 has not yet stopped, there is a risk that water will be blown away by the washing blades 1 as in the conventional case. It will also disappear.

Effects of the invention As described above, according to the invention, water is injected from the water inlet into the washing and dehydrating tank by being located between the outer circumference of the washing blade and the inner wall of the washing and dehydrating tank. In addition, since the water injection is performed as a shower water injection, the water injected from the water inlet does not directly hit the top surface of the washing blade as in the conventional case, and therefore the injected water scatters. Moreover, even if the laundry sticks to the inner wall of the washing/spinner tank after spin-drying before the rinsing process, the water from the water inlet will be sprayed directly onto the laundry over a wide area and evenly, allowing for faster rinsing. As a result, it has various excellent features such as being able to improve rinsing efficiency. In addition, even if the water inlet is L-shaped and turbulent flow occurs at the bent part, a filter can be placed at the bent part to prevent turbulent flow and prevent hindrance to shower water injection. Because it is set to L
Shower water can be reliably filled even with the shape of the water inlet.
