Abstract

PROBLEM TO BE SOLVED: To solve the problem in which: the cumulative use of a conventional fully automatic washing machine causes dirt outside a tub to adhere to laundry because the dirt outside the tub which is formed and increased between the outside of a dewatering tub and a water tub passes through the holes of the dewatering tub and flows into the inside of the dewatering tub together with water to adhere to the laundry.SOLUTION: A water backflow prevention mechanism is attached to each hole of a dewatering tub, thereby preventing dirt outside the tub formed and increased outside the dewatering tub from flowing into the inside of the dewatering tub.

Description

  The present invention relates to a fully automatic washing machine for home use that is intended for clean washing for general household use.

  In the dewatering tub of a conventional fully automatic washing machine for home use, the water outside the dewatering tub is coming and going inside the dehydration tub from the side and bottom holes of the dewatering tub.

  Hereinafter, a conventional home automatic washing machine will be described with reference to FIG. In the figure, there are many holes 9 on the side surface and bottom surface of the dehydration tank 3, and trash entangled with black mold, detergent waste, and detergent waste generated between the outside of the dehydration tank and the water tank 4 (hereinafter referred to as dirt outside the tank). Passes through the hole 9 together with water and flows into the inside of the dehydration tank and adheres to the laundry.

  In the conventional full-automatic washing machine for households described above, the water outside the dehydration tank comes and goes from the hole on the side of the dehydration tank and the hole on the bottom to the inside of the dehydration tank. There was a problem of flowing into and adhering to the laundry.

  The present invention is intended to solve the problems of the conventional configuration as described above, and is intended for a clean household use that does not allow the outside dirt generated and propagated outside the dehydration tank to flow into the inside of the dehydration tank. The purpose is to realize an automatic washing machine.

  In order to achieve the above object, the present invention consolidates the holes in the dewatering tank and attaches a water flow backflow prevention mechanism to the hole so that water does not flow from the outside to the inside of the dewatering tank. .

  As described above, since the dirt outside the tank does not flow into the inside of the dehydration tank by installing a water flow backflow prevention mechanism in the hole of the dehydration tank of the fully automatic washing machine for home use of the present invention, it is compatible with conventional dirt outside the tank. In addition to the cost of disassembling and cleaning requested by a contractor, the cost of washing the washing machine with a special detergent yourself, and the economic burden of replacing the product by giving up the original restoration, there is no compromise use remaining dirty, It is possible to provide a fully automatic washing machine that can always wash cleanly without any physiological disgust.

  Hereinafter, an embodiment of the present invention will be described with reference to FIG.

  In the figure, reference numeral 1 denotes a water flow backflow prevention mechanism, which is provided with a slit 2, which is attached to a hole 9 formed in the lower part of the dewatering tank. 4 is a water tank, 5 is a pulsator, 6 is a separator, 7 is a drive motor, 8 is a drain valve, and 9 is a hole.

  The operation of the above configuration will be described below. First, when water is supplied to the inside of the dehydration tank 3 in the water supply process, the water passes through the slit 2 while expanding the slit 2 of the water flow backflow prevention mechanism 1 and is also supplied to the outside of the dehydration tank 3 as desired. Water is supplied to the water level.

  In the washing process, the slit 2 is closed by the elastic effect of the water flow backflow prevention mechanism 1, and the water outside the dewatering tank can be washed without flowing into the inside of the dewatering tank by the water flow backflow prevention effect.

  In the drainage process, when the drain valve 8 is opened and drained, the water level outside the dewatering tank 3 drops and the water inside the dewatering tank 3 passes through the slit 2 while expanding the slit 2 of the water flow backflow prevention mechanism 1. It goes out of the dehydration tank and is drained.

  In the dehydration process, when the dewatering tank 3 rotates with the drain valve 8 open, the water in the clothes is dehydrated, and the water passes through the slit 2 while expanding the slit 2 of the water flow backflow prevention mechanism 1 and out of the dewatering tank. To be discharged.
