Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of the lint filter section of a washing machine for washing clothes and the like.

BACKGROUND ART Conventionally, the configuration of a lint filter section of this type of washing machine will be explained with reference to FIG. 4. A balancer 2 disposed above a washing tub 1 houses a filter frame 4 to which a lint filter 3 is fixed. Recess 5
is formed. This filter frame 4 is A
The upper part of the filter frame 4 is provided with a hook hole 6 for attaching and detaching it by pulling it by hand.

Problems to be Solved by the Invention In such a conventional configuration, by stirring the clothes in the washing tub 1, the clothes 7 in the washing tub are turned in the direction B, and the water is scattered in the direction C. In this case, especially at a high water level, the water that is increased by a small amount of clothing and scattered in the C direction flies upwards of the balancer 2, and then reaches the inner wall of the outer box, the mechanism inside the outer box, and the electrical equipment inside the outer box. dripping,
Furthermore, it dripped onto the floor, creating a practical problem.

This invention solves these problems,
The purpose is to minimize the scattering of water from the filter part, prevent it from dripping into the outer box, and enable smooth washing operations even under the worst conditions when the water level is high and the load is small.

Means to Solve the Problem In order to solve this problem, the upper part of the filter frame is made into an inverted L shape, and a protruding rib is provided that protrudes inward of the washing tub. A reduced step surface is provided so that when the filter frame is attached, the line of this step surface and the lower surface of the protruding rib are approximately on the same plane.

Function: With this configuration, water that is fluidly splashed on the inner wall of the balancer or the inner wall of the washing tub due to the rotation of the clothes in the washing tub hits the lower surface and stepped surface of the inverted L-shaped protrusion of the filter frame and is scattered upward and outward. In addition to preventing this, the protruding ribs also act as a handle.

Embodiment Examples of the present invention will be described below in Figures 1 and 2.
This will be explained with reference to FIG. In Fig. 1, 8 is an outer box of the dehydrating washing machine, 9 is a washing tub and dehydrating tank (hereinafter referred to as the washing tub) which has a large number of dehydrating holes 10 on the side wall, and a stirring blade 11 is provided in the center of the bottom and form the pump vane 12. Further, a balancer 13 is fixed to the upper opening of the washing tub 9. Reference numeral 14 denotes an outer tub with a washing tub 9 inside, and an outer tub cover 15 is attached to the upper opening of the outer tub 9. Reference numeral 16 denotes a clutch mechanism, and the clutch mechanism 16 houses a washing/dehydrating switching clutch and a control device. A motor 17 is installed below the outer tank 14, and the power of the motor 17 is transmitted to the stirring blades 11 via a belt 18. Reference numeral 19 denotes a suspension that hangs and supports the outer tank 14 by the four corners of the upper support member 20 of the outer box 8;
Outer tank 1 by suspension 19 consisting of set
The lower support body 21 provided at 4 and the upper support body 20 of the outer case 8 are elastically connected to elastically support the outer tank 14.

Reference numeral 22 denotes a drainage hose for discharging water to the outside of the aircraft body via a pot 23, and is switched by opening and closing a drainage valve 24.

The clothes 25 are agitated by the rotation of the stirring blades 11, and at the same time, the water in the washing tub 9 is circulated by the pump blades 12, passes through the pumping channel 26, and is discharged into the lint filter 28 provided at the pumping channel opening 27. and is returned to the washing tub 9 to create a circulation path. The movement of circulating water is shown by arrow D, and the lint filter 28
The lint is collected by passing it through the tank.

In FIG. 2, the lint filter 28 is integrally formed with a filter frame 29 made of synthetic resin or the like. The upper part of the filter frame 29 has an inverted L shape with ribs 30 that protrude toward the inside of the washing tub 9.
has been established. In addition, a step surface 31 is provided in which the diameter of the upper part of the balancer is reduced so that the inner diameter wall portion of the balancer 13 is stepped on the circumference, and a step surface 31 is provided on the line of this step surface 31 so as to fit with the lower surface 32 of the protruding rib 30 of the filter frame 29. It is located in

In such a configuration, the clothes 2 in the washing tub 9
5 is a function in which the water turned in the E direction and fluidly scattered in the F direction is prevented from going upward by the protruding ribs 30 of the filter frame 29, and also by the stepped surface 31 of the balancer 13. demonstrate.

FIG. 3 shows the operation of attaching and detaching the filter frame 29, and the protruding rib 30 of the filter frame 29 is used as a handle to improve usability. Note that the balancer 13 is fixed to the convex portion 34 of the filter frame 29 and the balancer 13.
The stopper recess 35 is engaged with the stopper recess 35 to enable attachment and detachment.

Effects of the invention As described above, according to the invention, the upper part of the filter frame is formed into an inverted L shape, and a protruding rib that protrudes inward of the washing tub is provided, and the balancer has a smaller diameter at the upper part of the inner peripheral surface. By providing a stepped surface so that when the filter frame is attached, the line of this stepped surface and the lower surface of the protruding rib are flush with each other, thereby reducing the amount of fluid splashing water that occurs when agitating clothing, etc. It is possible to prevent the liquid from dripping outside the outer tank, thereby preventing the liquid from dripping onto the floor, mechanical parts, or electrical parts. Therefore, it has great practical effects, including improving the durability of the mechanism, ensuring the safety of the electrical equipment, and preventing dripping onto the floor.Furthermore, it improves the usability of the filter frame handle.
