Abstract

PURPOSE: To make it possible to positively and vertically circulate water in a washing/dehydrating tank without increasing its cost and without narrowing its inside volume. CONSTITUTION: A water pipe is integrally formed at a rotary vane 4. The water is admitted from an inlet 9 of the water pipe into the water pipe and the water entering the pipe is passed through the water pipe and is discharged upward from an outlet 10 in rotation of the rotary vane 4 at the time of washing and rinsing. The water is mingled by the rotary vane 4 and is positively circulated vertically, by which stirring water flow and vertical water flow are generated. A high washing effect is thereby obtd.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine such as a fully automatic washing machine and a two-tub type washing machine.

[0002]

2. Description of the Related Art In a fully automatic washing machine disclosed in Japanese Patent Laid-Open No. 1-146584, when a rotary blade rotates, its back blade pushes water around the rotary blade. The pushed water moves upward through the circulation passage formed on the inner wall of the washing / dehydrating tub by the force of the water, jets out from the outlet of the circulation passage, and drops downward in the washing / dehydrating tub. In this way, the water containing the detergent is positively circulated up and down in the washing / dehydrating tank, whereby the washing effect is improved.

[0003]

However, since the circulation path along the inner wall of the washing / dehydrating tub is required, the cost of the washing machine is increased. Also, the internal volume of the washing / dehydrating tub is reduced by the amount of the circulation path.

The present invention intends to provide a washing machine which can positively circulate water vertically to obtain a high washing effect without increasing the cost and narrowing the inner volume of the washing / dehydrating tub. It is what

[0005]

A washing machine of the present invention includes a washing tub, a rotary wing arranged in the washing tub, an inlet directed to receive water when the rotary wing rotates, and the receiving tub. And a water channel formed in the rotary blade, which has an outlet for discharging water upward.

[0006]

When the rotor rotates during washing, water enters from the inlet and is discharged upward from the outlet in the water passage formed in the rotor. As a result, a vertical sewage flow is positively generated by vertical circulation of water in the washing tub, and a high cleaning effect is obtained.

In this case, since it is not necessary to provide a large circulation path along the inner wall of the tank as in the conventional case, the cost increase is suppressed. Furthermore, since the large circulation path does not project into the tank, the inner volume of the tank does not become narrow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fully automatic washing machine according to an embodiment of the present invention will be described with reference to the drawings. An outer tub 1 is suspended and supported in an outer frame (not shown) of the washing machine, and a washing / dehydrating tub 2 is rotatably supported in the outer tub 1. Washing and dehydration tank 2
A large number of dehydration holes 3 are formed on the peripheral side wall. Furthermore,
A rotary blade 4 is arranged on the inner bottom of the washing / dehydrating tub 2.
At the time of washing and rinsing, only the rotary blades 4 are rotated (reversed periodically) and the clothes are stirred with water. When dehydrated,
The washing / dehydrating tub 2 and the rotary blades 4 simultaneously rotate at high speed to dehydrate the clothes.

The rotary blade 4 has a first, a second, a third and a fourth.
The water pipes (water channels) 5, 6, 7, and 8 are integrally formed. In each of these water pipes, the inlet 9 is oriented substantially tangentially to the outer circumference of the rotary blade 4 around the lower side of the rotary blade 4. Exit 1
0 is directed upward in the center of the rotary blade 4. And
Each of the water pipes is curved in an arc shape as shown in the drawing, and protrudes upward to form a blade portion of the rotary blade 4.

In this case, when the rotor blade 4 rotates in the direction (FIG. 4) during rotation of the rotor blade 4 during washing and rinsing, the inlets 9 of the second and fourth water pipes 6 and 8 positively move water. It will be in a state of being accepted. That is, in the second and fourth water pipes 6 and 8, when water enters from the inlet 9, the entered water is discharged upward from the outlet 10, and eventually the water is agitated by the rotary blades 4 and positively circulates vertically. A stirring water flow and a sewage flow are generated, and a high cleaning effect is obtained.

When the rotary blades 4 are reversed and rotated in the direction, the inlets 9 of the first and third water pipes 5 and 7 are now in a state of being positively oriented to receive water. That is, in the first and third water pipes 5 and 7, water enters from the inlet 9 and the entered water is discharged upward from the outlet 10. In this case also, the water is stirred by the rotary blades 4 and actively circulates vertically. However, a stirring water flow and an up and down water flow are generated, and a high cleaning effect is obtained.

[0012]

EFFECTS OF THE INVENTION According to the washing machine of the present invention, a vertical sewage flow can be positively generated and a high cleaning effect can be obtained. Further, as a structure for obtaining a high cleaning effect, a water channel having an inlet directed in a direction of receiving water when the rotor blades rotate and an outlet for discharging the received water upward,
It is only necessary to form the rotary blade integrally with the rotary wing, and it is not necessary to provide a large circulation path along the inner wall of the washing tub as in the conventional case, so that the cost can be suppressed. Furthermore, since the large circulation path does not project into the washing tub, the inner volume of the tub does not become narrow. Furthermore, since it is not a conventional structure in which upward water is dropped thereafter (noise is generated when the dropped water hits the water in the tank), noise reduction can be achieved.
