Description

washing ball {washing ball}

The present invention relates to a laundry ball that washes laundry through a silicone friction protrusion that rubs against the laundry, induces a flow of laundry water flow during the washing process, and improves the washing reliability of the laundry through clean washing of the laundry.

The washing machine has a central axis installed in the vertical or horizontal direction, and the potential energy, centrifugal force, friction force, etc. caused by a fall continuously generated as the rotating drum rotates in a state where laundry and washing water are mixed inside the rotating drum formed in a cylindrical shape. It is used to generate washing power. In the case of a normal laundry washing method using a washing machine, impurities or old dirt contained in the laundry are more easily removed, and various fragrances are added as additives to allow the laundry to emit fragrance after washing. Laundry is washed in a way to increase the cleaning effect by input, but when washing laundry using various detergents, excessive use of detergent may become a problem, and there is a problem that environment-friendly laundry treatment is impossible by aggravating water pollution. Accordingly, various methods for washing laundry while reducing the amount of detergent used have been proposed. For example, in Korean Patent Publication No. 10-2129175 (published on July 01, 2020) and Korean Registered Patent Publication No. 10-2232520 (announced on March 26, 2021), friction protrusions while reducing the amount of detergent used Disclosed is a 'washing ball' for washing laundry using the frictional force of However, conventional prefabricated laundry balls proposed to be put into a washing machine to wash laundry have a risk of being damaged by the washing water flow, are structurally complicated, and require excessive manufacturing costs, and are uniformly protruding from the outer surface of the laundry balls. There was a problem that the washing effect was not sufficient because the friction protrusion caused the tangle of the clothes during washing, and it was not possible to effectively collect or remove impurities including dust and other foreign substances included in the washing water. This is an impossible problem. Accordingly, the present applicant, the inventor of the present application, structurally simplifies the laundry ball sphere and uses the main material as a silicone material to manufacture it in one injection molding, thereby reducing damage and cost, while eliminating impurities such as fiber residues or dust contained in water flow. We propose a new laundry ball that can be effectively removed in the washing process and in the drying process afterwards.
