KR-20260066234-A - Single-hole type split assembly faucet

Abstract

The present invention relates to a single-hole split-assembly faucet. By simply combining a valve fixture and a valve cartridge, molded from stainless steel and a polyamide-based synthetic resin that is harmless to the human body, within a single independent single-hole main body, a more hygienic faucet is provided. Furthermore, since the parts are assembled without separate processing after casting during the manufacturing process, assembly and product productivity can be significantly improved. Additionally, advantageous maintenance is provided in terms of ease of use, as the parts can be easily replaced in the event of damage or contamination due to the nature of partial assembly.

1. In a single-hole split assembly faucet, The above faucet is, A main body (10) made of stainless steel having a cylindrical volume with an open top and bottom, a water outlet hole (10a) formed through the outer circumference to communicate with the interior, a water outlet pipe (10-1) attached thereto, and a female screw (10b) formed in the lower inner diameter, and A valve fixing body (20) is provided with a guide portion (21) having a depth from the top and an internal upper portion (21a) formed therein, and on the inner bottom of the guide portion (21), a water supply passage (22) that coincides with the water outlet hole (10a) on the outer surface, and a hot water passage (23) and a cold water passage (24) are respectively partitioned and formed therein. A valve cartridge (30) having a male screw portion (30a) and a male screw portion formed on the upper side to be guided to be fastened to the female screw portion (21a) on the guide portion (21) side of the valve fixing body (20), and having a multi-directional waterway (31) on the cross-section that communicates with the water supply passage (22) side of the valve fixing body (20) through a hot water supply line (1A) connected to the hot water passage (23) of the valve fixing body (20) through the interior of the main body and a cold water supply pipe line (2A) connected to the cold water passage (24), and a connecting shaft portion (32) provided on the upper side, and An operating lever (40) connected to the connecting shaft (32) of the above valve cartridge (30) to select and adjust water coming from the hot water and cold water sides through the multi-directional flow path (31) on the valve cartridge (30) side by moving up and down and left and right from the upper part of the main body (10) and to switch and discharge water to the outlet pipe (10a) side, and A one-hole split assembly faucet characterized by comprising a support member (50) having a guide hole (50b) in the center for penetrating the hot water supply line (1A) and the cold water supply pipe line (2A), wherein a male screw (50a) is formed on the outer circumference to be fastened to the female screw (10b) on the lower side of the main body (10) so as to fix the main body (10) vertically from the object to be installed.
2. In paragraph 1, A one-hole split assembly faucet characterized in that two grooves (20a) are formed on the outer circumference of the valve fixing body (20), and an O-ring (P) is fastened to the grooves and seated inside the main body (10) for assembly.
3. In paragraph 1, The above valve fixing body (20) is characterized by being molded from a heat-resistant polyamide-based synthetic resin material, forming a one-hole split assembly faucet.

Description

Single-hole split assembly faucet The present invention relates to a faucet, and more specifically, to a single-hole split-assembly faucet that improves the assemblability of 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, and a valve fixing body that switches the flow path, 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 significantly reducing manufacturing costs through a precise and simple combination with the product's components while maintaining an aesthetically pleasing appearance. 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. Meanwhile, regarding various types of faucets, single-hole type faucets installed on washbasins or sinks are installed using a clamp through a separate connecting pipe from the water supply pipe on the wall side. These single-hole type faucets are widely used for the purpose of providing simplicity through vertical installation from a clamp. The basic form consists of a body installed to stand vertically on a washbasin or sink, an operating lever provided on the upper or side thereof, and a valve cartridge, valve body, O-rings and packings for maintaining airtightness, hoses for supplying hot and cold water, etc. installed inside the body, all connected and combined. A discharge pipe is integrally provided on one side of the body, and the device is used in a form that allows water to be discharged or blocked depending on whether the operating lever is operated. The body, operating lever, and clamp of the aforementioned conventional faucet are mostly manufactured by casting using durable brass or zinc materials, and since their outer surfaces are treated with chrome-nickel plating to provide a smooth surface and gloss, there was a problem of increased manufacturing costs for the faucet.
