Description

[Detailed description of the invention] [Field of industrial application] The invention consists of a shell consisting of an upper cover and an undercover made of synthetic resin, and a metal water pipe member is provided inside this shell. It concerns faucets.

[Conventional technology]

Traditionally, faucets have been made of cast metal,
Because the shape is complex, a casting method using a sand mold must be used, and the surface of the cast must be carefully finished by grinding, polishing, etc.
Production costs tended to increase.

Therefore, in recent years, consideration has been given to making faucets made of synthetic resin that is easy to mold. That is, a synthetic resin upper cover and an undercover are engaged to form a faucet shell, and a metal water pipe member is installed inside the faucet shell. Note that this upper cover may be plated with metal to enhance its design.

[Problem that the invention attempts to solve]

If the upper cover or undercover and the water pipe member are assembled in such a state that they are in contact with each other, heat may be transferred from the water pipe member to the upper cover or under cover, and these may become hot. (Please note that even if the design is designed to provide the required clearance between these covers and water pipe members,
Depending on dimensional errors and assembly accuracy, the water pipe member may come into contact with the cover. ) If the upper cover gets hot, it will be hot to the touch and the plating on its surface may peel off.

[Means for solving problems]

In the faucet of the present invention, a synthetic resin undercover and a synthetic resin upper cover are engaged to form a faucet shell, and a metal (e.g., cast metal) water pipe member is installed inside this shell. This faucet has a heat insulating material interposed at least in a portion between the inner surface of the upper cover and the water pipe member.

[Effect]

In the faucet of the present invention, since the heat insulating material is interposed between the upper cover and the water pipe member, the water pipe member does not come into direct contact with the upper cover and the like. Therefore, the upper cover etc. will not become hot.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an assembled perspective view of the main parts of a hot water mixing faucet according to an embodiment of the present invention, and FIG. 2 is a side sectional view of the same hot water mixing faucet.

The hot water mixing faucet according to this embodiment has an upper cover 10 made of synthetic resin, an under cover 12 made of synthetic resin, and a water passage pipe 14 made of cast iron. The undercover 12 includes a bottom seat part 12a that is seated on the top surface of the washbasin, and a water spout part 12b that extends forward from the center of the bottom seat part 12a. A hook portion 16 is integrally formed. The upper cover 10 has a shape that covers the undercover 12 from above, and includes a main body part 10a that covers the bottom seat part 12a, and a water spout cover part 1 that covers the water spout part 12b.
0b. Also, under cover 12
A plurality of claws 18 (total 3 in this embodiment) are provided upright on both sides and the tip of the water spouting portion 12b, and the water spouting cover portion 1 of the upper cover 10
0b is provided with a locking portion 20 consisting of a recessed hole that engages with the pawl 18, and the engagement between the pawl 18 and the locking portion 20 causes the upper cover 10 and the undercover 12 to be locked together. and constitutes the faucet shell 22.

In order to engage the claws 18 and the locking portions 20, it is only necessary to cover the upper cover 10 over the under cover 12 and then push it in, so this assembly can be performed extremely easily and quickly. Further, since both the upper cover 10 and the under cover 12 are made of synthetic resin, the claws 18 and the locking portions 20 can be integrally molded, and the manufacturing thereof can be carried out extremely cheaply and easily. Note that the upper cover 10 and the undercover 12, especially the upper cover 10, may be plated to enhance their aesthetic appearance.

The water pipe member 14 has a base end 14a and a water discharge part 14b extending forward from the base end 14a, and the base end 14a has a water leg 24 and a hot water leg 26. are connected. In addition, the base end portion 14a
Valve cases 28 and 30 are provided on the upper surface side, and are used to stop and adjust the flow rate of water and hot water flowing from the water leg 24 and the hot water leg 26 to the base end 14a of the water pipe member 14. It's becoming like that. Note that the main body portion 10a of the upper cover 10 has a hole 3 for inserting a spindle (not shown) projecting upward from the valve casings 28, 30.
2, 33 (33 is not shown) are provided,
A hot water handle (not shown) and a water handle 34 are attached to the upper end of this spindle. Further, the bottom seat portion 12a of the undercover 12 is provided with through holes 36 and 38 through which the water leg portion 24 and the hot water leg portion 26 are inserted.

A water outlet 40 is opened at the tip of the water pipe member 14, and a water outlet 12b of the undercover 12 is opened.
An opening 42 is provided at the tip, and a spout cap 44 can be screwed onto the spout 40 through the opening 42.

A chain 46 is secured to the hook portion 16 via a chain connection fitting 48 and a ring 50, and a drain cap 52 is connected to the tip of the chain 46 via a similar connection fitting 48 and ring 50. installed. Note that the bottom seat portion 12 of the undercover 12
A is a bolt 54 attached to the base end 14a of the water pipe member 14.
It is fixed in place.

A heat insulating material 56 is interposed between the inner surface of the upper cover 10 and the upper surface of the water pipe member 14 to prevent the water pipe member 14 from coming into direct contact with the upper cover 10. Therefore, situations such as the upper cover 12 becoming hot or the plating peeling off due to the difference in thermal expansion between the plating layer and the synthetic resin layer are reliably prevented.

In addition, in the present invention, a heat insulating material may be provided between the undercover 12 and the water pipe member 14. Further, as the heat insulating material, a sheet-like material may be used instead of the illustrated small piece-like material.

Although not particularly limited, in the present invention, heat-resistant materials that can withstand the temperature of hot water,
For durability and ease of assembly, materials with elasticity are preferred, and synthetic resin foams such as synthetic rubber, or synthetic resin foams such as sponge, nitrile rubber, cork, etc. are preferred.

[Effect of idea]

As described above, the present invention constructs a faucet shell by connecting an easily moldable synthetic resin upper cover and an undercover, and installs a metal water pipe member inside this shell. It is extremely easy to mold and assemble the shell, and it is inexpensive. In addition, even if the water pipe member is a cast product, no special surface finishing work is required, and it is easy and inexpensive to manufacture.

Furthermore, since a heat insulating material is interposed between the upper cover and the water pipe member, the upper cover does not get hot or its plating peels off, providing excellent usability and durability.
