Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application 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. Interior water tank 3
, an outer box main body 4 containing the water receiving tank 3 and the washing/dehydrating tank 2, and a top plate 6 installed on the upper surface of the outer box main body 4 and having a laundry input port 5.
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 was arranged to be located on the upper surface of the washing wing 1 provided approximately at the center of the inner bottom of the dewatering tank 2.
However, in this configuration, when water is injected from the water inlet 9, the injected water hits the washing blade 1 directly, so the water not only scatters around but also upwards. When the lid 10 of the laundry input port 5 is open, water may leak out from the laundry input port 5 and wet the installation floor. Furthermore, when moving to the rinsing process after washing, it has recently become common to perform a dehydration process after washing in order to improve the rinsing efficiency, and water is poured for rinsing immediately after the completion of this dehydration process. In this case, since the water is injected before the washing and dewatering tank 2 has completely stopped, this water will directly hit the washing blade 1, which is still rotating, and the water will scatter with force and spread around the surrounding area. As mentioned above, there was a risk that the product would splash and wet the installation floor.

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 center of the tank, if water is poured into the washing/spinning tank 2 after this spin-drying,
This injected water does not directly splash on the laundry, and the laundry becomes immersed in water only once the water has accumulated in the washing and dehydrating tub 2, resulting in a decrease in rinsing efficiency.

Purpose of the invention The present 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-mentioned object, the present invention provides a structure in which water is injected from a water inlet into the washing and dehydrating tub by being located between the outer periphery of the washing blade and the inner wall of the washing and dehydrating tub. According to this configuration, the water injected from the water inlet will not directly hit the top surface of the washing blade, so the injected water will not scatter, and moreover, Even if the laundry sticks to the inner wall of the washing and dehydrating tub after spin-drying, water is injected from the water inlet between the outer periphery of the washing blade and the inner wall of the washing and dehydrating tub. The water injected from the water inlet is applied to the laundry, and as a result, rinsing can be performed quickly, thereby improving rinsing efficiency.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Note that in FIG. 2, the same parts as those in FIG. 1 showing 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 FIG. 2, in one embodiment of the present invention, opposite to the opening end surface 9a of the water inlet 9,
A rib 11 hanging downward is integrally formed on the top plate 6, and the lower end surface of the rib 11 projects downward from the opening end surface 9a of the water inlet 9.
With this configuration, the water injected from the water supply valve 7 through the hose 8 hits the rib 11 and its direction is changed, and the water flows between the outer periphery of the washing blade 1 and the washing and dewatering tank 2. Since the water falls between the washing wing 1 and the inner wall, the injected water no longer hits the upper surface of the washing wing 1 as in the conventional case.
It can reliably prevent water from splashing. 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 is directly applied to the laundry 12 stuck to the inner wall of the washing and dehydrating tub 2, so that the laundry 12 can be rinsed quickly. As a result, efficient rinsing can be performed. Furthermore, even if water is injected in the next rinsing process after spin-drying is completed and the rotation of the washing/spin-drying tank 2 has not yet stopped, water will be blown around the washing blade 1 as in the conventional case. There will be no fear.

In the above embodiment, a rib 11 that hangs downward is provided on the top plate 6 in opposition to the opening end surface 9a of the water inlet 9. For example, a rib 11 corresponding to the rib 11 may be Even if it is provided on the side of the water inlet 9 and water is injected downward from the lower end surface of the water inlet 9, the same effect as in the above embodiment can be obtained, and the present invention is not limited to the structure of the above embodiment. It's not something you can do.

Effects of the Invention As described above, according to the present 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. Because of this structure, the water injected from the water inlet no longer hits the upper surface of the washing blade directly as in the conventional case, and therefore the injected water does not scatter, and moreover, the Even if the laundry sticks to the inner wall of the washing/spinner tub after spin-drying, the water from the water inlet is directly sprayed onto the laundry, allowing for faster rinsing, thereby improving the rinsing rate. It has various excellent features such as the ability to
