JP-2026075284-A - Faucet device

Abstract

[Problem] To provide a faucet device that allows the outer cover to be properly assembled to the housing containing the cartridge without requiring high dimensional precision. [Solution] The faucet device 1 includes a bottomed cylindrical housing 5 that encloses a hot and cold water mixing cartridge 4 with a stopper rod 4B protruding axially upward, a cylindrical outer cover 6 that fits over the housing 5 from the axially upward side to surround it, an annular mounting groove 7D formed on the outer circumferential surface of the housing 5, and an O-ring 9 that is fitted into the mounting groove 7D. The outer cover 6 has a position regulating portion 6D that comes into contact with the housing 5 from the axially upward side, and a plurality of claw portions 6F that come into contact with the O-ring 9 from the axially downward side.

Claims (4)

1. A faucet device comprising a bottomed cylindrical housing that encloses a cartridge for mixing hot and cold water with a stopper rod protruding axially upward, and a cylindrical outer cover that covers the housing from the axially upward side so as to surround it, An annular mounting groove formed on the outer circumferential surface of the housing, It comprises an annular elastic member that is fitted into the mounting groove, A faucet device having an outer cover that has a position-regulating portion that is applied to the housing from the axial upper side and a retaining portion that is applied to the elastic member from the axial lower side.
2. A faucet device according to claim 1, A faucet device having an outer cover having a rotation-preventing portion located axially above the retaining portion, which prevents rotation by contact with the housing in the circumferential direction.
3. A faucet device according to claim 1 or claim 2, The retaining portion is made up of a plurality of claws formed on the inner circumferential surface of the outer cover, separated in the circumferential direction. A faucet device in which the spaces between each of the multiple claw portions are recesses that create indentations on the inner circumferential surface of the outer cover.
4. A faucet device according to claim 1 or claim 2, The housing comprises a base that supports the cartridge from the axial lower side, and a cylindrical retaining member that is screwed into the base to press the cartridge from the axial upper side. A faucet device in which the mounting groove is formed on the outer circumferential surface of the base, and the position regulating portion is applied to the pressing member from the axial upper side.

Description

This invention relates to a faucet device. More specifically, it relates to a faucet device having a bottomed cylindrical housing that encloses a hot and cold water mixing cartridge with a stopper rod protruding axially upward, and a cylindrical outer cover that fits over the housing from the axially upward side, surrounding it. Patent Document 1 discloses a cylindrical outer cover that covers the outside of the faucet body of a single-lever faucet. The outer cover is fitted over a cylindrical retaining member that holds down the hot and cold water mixing cartridge, which is assembled to the faucet body, from above. This fitting allows a locking projection protruding from the inner surface of the outer cover to pass axially through a guide groove formed on the outer surface of the retaining member. Furthermore, after being placed over the outer cover, the outer cover is rotated around its axis relative to the retaining member. This causes the locking projection of the outer cover to be retract into a rotationally bendable retraction groove formed at the end of the guide groove. As a result, the outer cover is set in a state where it is prevented from coming off axially relative to the retaining member. Patent No. 5954689 This is a perspective view showing the schematic configuration of a faucet device according to the first embodiment.This is a disassembled perspective view with the handle removed upwards.This is a disassembled perspective view with the outer cover removed from the top.This is an exploded perspective view with the retaining member removed from the top.This is a perspective view of the outer cover from the bottom.This is a cross-sectional view of the faucet device taken along the line VI-VI in Figure 5. The embodiments for carrying out the present invention will be described below with reference to the drawings. 《First Embodiment》 (Outline configuration of faucet device 1) First, the configuration of the faucet device 1 according to the first embodiment of the present invention will be described using Figures 1 to 6. In the following description, when directions such as front, back, up, down, left, and right are indicated, they refer to the respective directions shown in each figure. The directions shown in each figure represent the direction as viewed from the user standing in front of the faucet device 1. In the following explanation, if a specific reference figure is not shown, or if there is no corresponding symbol in the reference figure, refer to one of Figures 1 to 6 as appropriate. Furthermore, in the following explanation, "axial direction" refers to the vertical direction within each figure. As shown in Figure 1, the faucet device 1 according to this embodiment is configured as a single-lever type mixer faucet installed on a washbasin vanity. Specifically, the faucet device 1 has a two-hole type configuration in which the faucet body 2, equipped with a lever handle 3, and a water outlet (spout) (not shown) that dispenses hot and cold water are installed side by side on the countertop C of the washbasin vanity. The faucet body 2 is installed by being fitted from above into a mounting hole (not shown) drilled in the countertop C. This ensures that the piping (not shown) running inside the faucet body 2 passes through the mounting hole to the underside of the countertop C. The legs of the faucet body 2, which are passed through the mounting hole (not shown), are secured to the countertop C by being tightened from the underside of the countertop C with lock nuts. The faucet body 2 is configured such that the user can switch between water flow and shut-off, and adjust the ratio of hot and cold water being dispensed, by operating a lever handle 3 attached to its upper part. This switching between water flow and shut-off, and the adjustment of the hot and cold water mixture ratio, is performed by a cartridge 4 built inside the faucet body 2. As shown in Figure 2, the cartridge 4 has a cylindrical main body 4A and a rectangular plug rod 4B extending upward from the upper center of the main body 4A. The plug rod 4B is connected to the main body 4A so that it can be rotated around an axis extending in the vertical direction and moved up and down around an axis extending in the horizontal direction. The lever handle 3 is fitted onto the valve rod 4B from above and integrally fastened with a screw (not shown). As a result, the valve rod 4B is operated so that it rotates up, down, left, and right in conjunction with the operation of the lever handle 3. The cartridge 4 controls the switching between water flow (discharge/stop) and the mixing ratio of the hot and cold water supplied to the main body 4A by the rotation of the valve rod 4B up, down, left, and right. Since the basic configuration of the cartridge 4 is identical to that disclosed in Japanese Patent Application Publication No. 2020-46067 and other documents, a detailed explanation is omitted. As shown in Figure 3, the faucet body 2 co
