Description

TECHNICAL FIELD The present invention relates to a faucet device, and more particularly to a faucet device capable of discharging and stopping hot water mixed with hot water supplied from a hot water supply source and water supplied from a water supply source.

2. Description of the Related Art Conventionally, as a faucet device capable of discharging and stopping hot water mixed with hot water supplied from a hot water supply source and water supplied from a water supply source, for example, a faucet is disclosed in Patent Document 1. A device is known that has an outer shell member formed in a shape corresponding to the type of the device.
In addition, a separate casing member is inserted inside the outer shell member of this conventional faucet device.

EP-A-2586919

However, in the conventional water faucet device described above, the casing member inserted inside the outer shell member is made of a resin material. Accordingly, it is necessary to prepare a mold for injection molding, which raises the problem of high manufacturing costs.
Moreover, the resin-made casing member of the conventional water faucet device has a problem that its strength is lower than that of a metal-made casing member, and the durability against aging and the like is also low. As a result, in order to ensure long-term safety, there is a problem that maintenance costs such as inspection and parts replacement are costly.

On the other hand, if the casing member of a conventional water faucet device is cast using a metal such as a copper alloy that is different from the resin material, it will be necessary to take measures to restrict the elution of lead from the copper alloy. There is also a problem that the size of the casing member itself is increased, or a problem that it is easily affected by fluctuations in the copper price.
In addition, considering the fact that the faucet device is constantly exposed to hot water, if a stainless steel material with high corrosion resistance is used as the casing member, there is also the problem that it is difficult to machine the stainless steel material with high machining accuracy.
Therefore, we have realized the elimination of copper alloys and castings, and the utilization of materials other than copper alloys. How to raise it is an issue that has been requested in recent years.
Furthermore, in order to ensure the watertightness of the internal flow path of the casing member, it is necessary to provide a sealing member such as an O-ring inside the casing member. However, when a thin metal plate or pipe is used as the casing member, there is also the problem that it is difficult to form a groove for holding the seal member in the casing member by cutting or the like.
