Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a structure for attaching a decorative cover to a mixer faucet used for pouring hot water at an appropriate temperature into a bathtub.

(B) Conventional technology Conventionally, as a type of bathtub, there is a bathtub equipped with a mixing faucet unit attached to one side of the bathtub to mix hot water and water to create bath water at an appropriate temperature. A faucet body, a water supply pipe and a hot water supply pipe that supply water and hot water to the mixer faucet body respectively, a manual switching valve that adjusts the supply of mixed water from the mixer faucet body to the discharge fitting, and a pre-mixed water supply pipe to the bathtub. It consists of a metering valve that supplies only the set amount of hot water.

In addition, in order to be able to freely and easily operate the mixing faucet unit from inside the bathtub, almost the entire unit is buried within a mounting base provided adjacent to the bathtub, and only the handle operating portion is located through an opening provided at the top of the mounting base. It is made to protrude from the top surface of the mounting base through the section.

Furthermore, such a mixing faucet unit has a gasket placed on the top surface of the mixer faucet unit in order to prevent water from entering into the inside of the mount through the above-mentioned opening. In order to improve the beauty of the top surface of the table, a decorative cover is attached to the top of the cover.

(c) Problems to be solved by the invention However, this mounting structure had the following problems.

Because the sealing structure used in the gap between the decorative cover and the handle operation part is insufficient, splashing water penetrates into the concrete that forms the mounting base through the gap, causing corrosion of the concrete and the buried part of the mixing bottle unit. .

Since the seal structure has a complex structure,
It cannot be easily disassembled and reassembled, making maintenance of the mixing faucet unit complicated.

An object of the present invention is to provide a mounting structure for a decorative cover in a hot water mixer faucet that can solve the above-mentioned problems.

(d) Means for solving the problem The present invention consists of a mixing faucet unit in which the operating handle protrudes above the top surface of the mixing faucet unit mounting base, and a mixing faucet unit in which only the portion corresponding to the base of the operating handle is opened. It is arranged in the annular space formed between the seal with a decorative cover placed on the stopper unit mounting base, the inner surface of the opening of the seal and the outer surface of the base of the operation handle, and the inner female threaded part is operated. A sealed envelope body is screwed onto the external male threaded part of the base of the handle part, and a sealed envelope body is provided protruding from the upper part of the sealed envelope body, and the lower surface thereof is pressed and superposed onto the decorative cover part around the opening of the packing by the screwing. an upper flange, a cap that is fitted around the outer surface of the base of the operating handle, and that the upper flange of the sealed envelope body is removably fitted into an annular groove with an opening at the lower end provided on the outer periphery of the cap; This invention relates to a mounting structure for a decorative cover for a hot water mixer faucet, which comprises an O-ring press-fitted between the inner wall surface of the cap and the outer wall surface of the base of the operating handle.

(e) Effect When constructing such a mounting structure, first open the part of the gasket with the decorative cover attached to the top surface that corresponds to the handle operation part of the mixing faucet unit, and insert the mixing faucet unit mounting base into the opening of the gasket. Insert the handle operation part that protrudes upward from the top surface, and place the packing on the top surface of the mounting base.

Next, fit the sealed envelope body into the handle operating part from above, screw the internal female threaded part into the external external threaded part of the base of the handle operating part, and attach the decorative cover by the bottom surface of the upper flange of the sealed envelope body. Press the periphery of the opening.

Thereafter, an annular cap having an O-ring on its inner wall is fitted onto the upper flange of the sealed envelope from above, and the O-ring is pressed against the outer surface of the handle operating section.

This makes it possible to reliably prevent water from entering the interior of the mount through the decorative cover.

(F) Effects With the configuration described above, the present invention has the following effects.

A cylindrical body that is threadedly engaged with the outer surface of the handle operating section and presses its upper flange against the decorative cover, and a cylindrical body that is fitted onto the upper flange of the cylindrical main body and whose inner wall is pressed into contact with the outer surface of the handle operating section. By working with a cap that has an O-ring,
It is possible to reliably prevent water from entering the inside of the mount through the decorative cover, and it is possible to effectively prevent corrosion of the inside of the concrete and the buried part of the mixing faucet unit.

In addition, the O-ring provided on the inner wall surface of the cap has appropriate slip resistance against the outer surface of the handle operating section, so while the cap can be attached and detached, it is possible to reliably prevent the cap from falling off. Maintenance of the mixing faucet unit can be performed extremely easily and reliably.
