Abstract

PURPOSE:To collect waste yarn on the center of the normal of centrifugal rotation of a washing machine and also prevent the waste yarn collected from flowing back by forming a float-and-sink ball as a center core which is rotated by centrifugation inside a filter above the center of the normal of the washing machine. CONSTITUTION:In a washing machine, a filter bag 2 is hanged and attached to the periphery of a ring 1 and a filter which is open at its upper face and in which the ring 1 is made to float on the surface of water with the filter bag 2 suspended in water is formed, and water 4 and air 3 are injected by a proper amount into a float- and-sink ball 5 to form a centrifugal float-and-sink ball and the float-and-sink ball 5 is installed in the filter to form a centrifugal filter. When washing operation is stopped, the float-and-sink ball 5 floats up and its spherical face makes contact with the inner periphery of the ring 1 of the filter and blocks the opening of the filter, and when the washing machine is actuated, the float-and-sink ball 5 in the filter is caused to float and sink through centrifugation under the pressure of water flow centrifugated above the center of the normal of the washing machine and opens the opening of the filter. As a result, waste yarn and fine solid matters collected in the filter bag of the filter are utterly prevented from floating and flowing back, thus effectively collecting the waste yarn and fine solid matters.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to a centrifugal rotary filter for a lint counter for a washing machine.

(Prior Art) Conventionally, the lint counter in a washing machine has been fixed to the inner wall with a suction cup, but the suction cup is easily attached and detached. When washing is stopped, the lint collected in the lint counter tends to float up and flow back out. Since the lint collector is located on the inner peripheral wall of the washing machine, there is a problem in that the collection of lint is insufficient.

(Problems to be Solved by the Invention) In view of the above problems in the lint counting device of a washing machine, this invention collects and recovers lint on the vertical center of the centrifugal rotation of the washing machine, and collects and collects the collected lint. The purpose is to prevent backflow.

(Means for Solving Problem 11) Based on the centrifugal rotating filter shown in FIG. 1 when washing is stopped and the centrifugal rotating filter shown in FIG. A floating ring 1 is floated above the water surface and the filter bag 2 is suspended in the water to form a filter with an open top surface, a floating ball 5 is displayed, and the floating method 5 is built in the filter and centrifugally rotated. A filter is formed, and when washing is stopped, the spherical surface of the flotation method 50 comes into floating contact with the inner periphery of the floating ring 1 of the filter to block and seal the opening of the filter, and when washing is in operation, the flotation method 50 in the filter is suspended. 5 is centrifugally rotated on the vertical center of the washing machine in response to the water flow pressure, centrifugally rotates up and down to open the opening of the filter, and can freely rotate centrifugally and float up and down in the filter on the vertical center of the washing machine. Circulation tube 8 in Fig. 3 of the centrifugal rotary filter configured with the floating-sinking method 5 as a central core for centrifugal rotation.
Based on the centrifugal rotary filter in the washing machine, the centrifugal rotary filter in the circulation tube 8 is constructed such that the centrifugal rotary filter is layered inside the circulation tube 8 and the cap 7 is screwed into the circulation tube 8 above the vertical center of the washing machine (function). To describe in detail the operation of the invention according to Fig. 1, in the centrifugal rotary filter shown in Fig. 1, a floating ring is floated above the water surface of the washing machine, and a filter bag is suspended in the water to form the open-shaped filter. . The centrifugally rotating spherical surface of the flotation method comes into floating contact with the inner periphery of the floating ring to block and seal the opening of the filter, completely preventing the lint and fine solid particles collected in the filter bag from floating and backflowing. .

Fig. 2 In a centrifugal rotating filter during washing operation, the flotation method in the filter opens the opening of the filter in response to the pressure of the water flowing down in the centrifugal rotation, and the centrifugal rotation and flotation occur on the vertical center of the washing machine. This is a centrifugal rotary filter that concentrates, collects and collects lint and fine solid matter by centrifugal rotation, using a flexible floating-sinking method as its core. During the washing operation of the centrifugal rotary filter in the circulation cylinder shown in FIG. The opening of the washer is opened, and the lint and fine solids are collected and collected using a floating method that allows centrifugal rotation and free floating on the vertical center of the washing machine. When the washing is stopped, the spherical surface of the flotation method floats into contact with the inner periphery of the float to block and seal the opening of the filter, completely preventing the lint and fine solids collected in the filter bag from floating and backflowing. It is a centrifugal rotating filter inside the circulation cylinder that can prevent
