KR-20260066235-A - Split assembly faucet

Abstract

The present invention relates to a segmented assembly type faucet. It provides a more hygienic faucet through a simple combination of parts including a valve fixture molded from a polyamide-based synthetic resin material harmless to the human body within a main body made of stainless steel, a water outlet pipe including a valve cartridge that switches the flow path to determine the direction of water supply, and a shower switching valve unit. Furthermore, since the parts are assembled individually without separate processing after casting during the manufacturing process, assembly and product productivity can be significantly improved. Additionally, it offers advantages in maintenance during use, as the parts can be easily replaced due to the nature of partial assembly in the event of damage or contamination.

A valve seating hole (62c) is formed that is stepped from the valve installation hole (62b) with a smaller diameter and has a water discharge port (62c-2) formed in the inner diameter to discharge water towards the discharge pipe (50) together with a female screw portion (62c-1). A split-assembly faucet characterized by comprising a valve body (63) that is split-assembled at the upper and lower portions of the valve installation hole (62b) and valve seating hole (62c) to block or open the water discharge port (62c-2), and a hose connector (64) that is connected to or separated from the valve body (63) and connected to a shower hose on one side.
4. In paragraph 3, A split assembly faucet characterized by having a circular groove (62d) on the outer circumference of the valve assembly body (62) and an O-ring (P) fastened to the groove so as to be slidably assembled into the inner diameter of the connecting pipe body (61).

Description

Split assembly faucet The present invention relates to a faucet, and more specifically, to a segmented assembly type faucet that improves the assembly of parts related to a body part constituting the faucet, a valve cartridge installed inside the body and linked with a lever to open or block the water flow path, a valve fixing body including the valve cartridge, a water outlet pipe, and a shower switching valve unit, thereby eliminating a separate polishing process applied to the exterior compared to products made by combining a faucet body and components typically manufactured in a casting form, and allowing for a beautiful exterior while significantly reducing manufacturing costs through a precise and simple combination of the product's components. Generally, faucets are installed and used in bathrooms or kitchen sinks, and are designed to allow the use of hot and cold water in connection with a boiler. Typically, a faucet is used in combination with numerous parts (valves, control levers, packings, connecting hoses, etc.), excluding the body that forms the exterior shape; among these parts, the main body is typically made of brass, which is easy to cast. However, the production of faucet bodies by casting involves significant environmental pollution, and due to the nature of the casting process, harmful components (such as graphite and impurities) remain in the body. This poses a health risk to the human body, particularly in the drinking water sector, when the product is installed and used. Furthermore, the poor environmental conditions associated with the casting process have led to its avoidance. Meanwhile, when the faucet body is applied as a product and used in actual use, the internal body of the faucet becomes severely corroded by tap water due to prolonged use compared to the initial product, which can lead to serious hygiene problems. In addition, when using hot water, the brass faucet body transfers heat quickly, posing a problem where the elderly or young children can easily suffer burns if they accidentally come into contact with the body. In addition, since the main body of the faucet fitting described above is manufactured as a single unit, there is a disadvantage that the manufacturing cost increases because a different mold must be made overall to produce similar products. In light of the above points, Korean Registered Patent No. 10-1064920 (Title: Method for manufacturing a main body for a faucet fitting and a main body of a faucet fitting, hereinafter referred to as the 'Patent Document') is disclosed. The above patent document improves a faucet body manufactured by casting from a single brass material by forming a double molded assembly inside the body that is harmless to the human body, has favorable heat resistance, and does not cause any corrosion, thereby resolving hygiene issues, burn problems caused by heat transfer, and durability issues associated with the use of a conventional faucet body, and reducing manufacturing costs for design diversity. A method for manufacturing a faucet fitting for this purpose comprises the following steps: a method for manufacturing a faucet fitting body having a hot water inlet and a cold water inlet provided from both sides, a water outlet integrating the hot and cold water inlets provided, and a valve for blocking the flow path and a lever for adjusting the valve provided at the top; wherein the faucet fitting body is made of brass material and each part is molded in a divided manner, and is molded into a reference body on which the valve is installed, a first assembly having a hot water inlet formed therein, a second assembly having a cold water inlet formed therein, and a third assembly having a water outlet formed therein; a step of double injection molding an internal molding assembly having a flow path and a connecting assembly part made of a polyamide resin composition within the reference body and the first to third assemblies, respectively; and a step of joining the first to third assemblies to the reference body so as to form a single faucet fitting body. It is manufactured by the step of plating nickel-chrome on the exterior of the faucet body to reinforce and conceal the joined parts of the faucet body. However, since the main body of the faucet in the aforementioned patent document is manufactured using external plating with nickel-chrome in a segmented assembled state, while there is an advantage in reducing manufacturing costs, it requires a polishing process to make the segmented connecting parts as smooth as possible before the external plating takes place, and consequently, there is a problem in that the polishing process and the inspection time for the product are long.
