JP2012-214992A

  The faucet device of patent document 1 is installed in a kitchen, a washroom, a bathroom, etc., for example. Therefore, the faucet device can be exposed to hot water, detergent, tableware stains, etc. on a daily basis. In the faucet device of Patent Document 1, a seam exists between the base member and the cover member. Since the cartridge is accommodated in the cover member and the cover member has to be relatively large, the seam is positioned relatively downward with respect to the main body. For this reason, when hot water, detergent, tableware stains, etc. jump, they easily reach the seam. Accordingly, hot water can enter the main body from the seam, and detergent, dish soil, etc. can accumulate in the seam. As a result, frequent cleaning of the faucet device may be required from a hygienic point of view.

  In addition, faucets installed in kitchens, washrooms, bathrooms, and the like are also required to have a beautiful appearance in order to stimulate consumers' willingness to purchase and provide a comfortable feeling of use. For this reason, as a component constituting the outer surface of the faucet device, a resin whose surface is plated with metal is generally used. However, in the faucet device of Patent Document 1, the cartridge is directly attached in the cover member. Therefore, corrosion may occur between the metal forming the housing of the cartridge and the metal plating on the surface of the cover member due to contact with the hot water that has entered from the joint between the base member and the cover member.

  By the way, the cartridge is a consumable item and needs to be replaced in about 5 to 10 years. At this time, if corrosion occurs between the cover member and the cartridge, the cartridge must be replaced after the cover member is broken and removed, and the replacement work may take time and effort. In addition to the new cartridge, a new cover member is also required, which can increase the replacement cost.

  Therefore, the present disclosure describes a water faucet device that can realize excellent hygiene and can easily and inexpensively replace a cartridge.

  A faucet device according to one aspect of the present disclosure includes a main body, a lever, and a water discharge head. The main body is disposed on the distal end side of the main pipe, the main pipe having at least a surface made of metal, the branch pipe extending from the main pipe and having the water discharge head disposed on the distal end side, the cartridge disposed in the main pipe, and the main pipe. And a tip member that partially covers the top of the cartridge. The lever is connected to the cartridge on the distal end side of the main tube so as to cover the distal end member. The cartridge includes an adjustment mechanism configured to be able to adjust a mixing amount and / or a flow rate of hot and cold water according to an operation of a lever, and a housing made of at least a surface having an adjustment mechanism disposed therein. The tip member is a resin fastening ring configured to be fastened to the upper end of the housing, and a cosmetic that surrounds the outer peripheral surface of the fastening ring and is rotatably attached to the fastening ring. Including rings. The fastening ring is provided with an engaging portion on the upper end side of the fastening ring that can be engaged with a detachable tool for attaching / detaching the fastening ring to / from the housing.

  In the faucet device according to one aspect of the present disclosure, the distal end member is disposed on the distal end side of the main pipe, and the lever covers the distal end member. For this reason, the joint between the main pipe and the tip member is positioned relatively above the main body. Therefore, even if they jump in an environment that can be exposed to hot water, detergents, tableware stains, etc. on a daily basis in the kitchen, washroom, bathroom, etc., it is difficult for hot water to enter from the seam, and detergents, tableware stains, etc. Hard to adhere to seams. As a result, it becomes easy to keep the faucet device clean.

  In the faucet device according to one aspect of the present disclosure, at least a surface has a metal fastening ring fastened to an upper end portion of a metal housing, and at least a metal decorative ring has an outer peripheral surface of the fastening ring. It is attached to the fastening ring so as to surround it. Therefore, since the fastening ring is interposed between the cartridge and the decorative ring, it is difficult to directly contact them. Therefore, it is possible to suppress the occurrence of corrosion between the metal on the surface of the cartridge and the metal on the surface of the decorative ring. As a result, the cartridge can be replaced without destroying the tip member. In other words, the original tip member can be used as it is when the cartridge is replaced. Therefore, the replacement cost can be suppressed. As described above, according to the water faucet device according to one aspect of the present disclosure, it is possible to realize excellent hygiene and simple and inexpensive replacement of the cartridge.

  By the way, in the faucet device of patent document 1, the cover member was directly attached to the main pipe of the base member. Therefore, in order to attach the cover member to the base member using a tool, it has been common to provide the outer surface of the cover member with concavities and convexities that engage with the tool. In this case, the aesthetic appearance of the main body of the faucet device may be impaired by the unevenness. In addition, sanitary concerns may arise due to accumulation of hot water, detergent, tableware stains, and the like on the unevenness. On the other hand, considering the aesthetics of the cover member, it is also possible to manually attach the cover member to the base member without providing irregularities on the outer surface of the cover member. In this case, it is difficult to attach the cover member to the base member with an appropriate torque, which may affect the performance of the cartridge fixed by the cover member.

  On the other hand, in the water faucet device according to one aspect of the present disclosure, the fastening ring is provided with an engaging portion that can be engaged with a detachable tool for detaching the fastening ring from the housing on the upper end side of the decorative ring. ing. The decorative ring is rotatably attached to the fastening ring. For this reason, by causing the attaching / detaching tool to act on the engaging portion of the fastening ring, the fastening ring is attached to and detached from the housing without providing the engaging portion on the outer surface of the decorative ring exposed to the outside. Therefore, the fastening ring can be attached to the housing with an appropriate torque by the attaching / detaching tool, the aesthetic appearance of the decorative ring can be improved, and the faucet device can be easily kept clean.

  In addition, in the faucet device according to one aspect of the present disclosure, the tip member has a double structure of a fastening ring and a decorative ring. Therefore, a gap is generated between the fastening ring and the decorative ring. Therefore, the presence of the gap can reduce water flow noise generated when hot water is supplied from the faucet device, and can suppress condensation that may occur on the outer surface of the decorative ring.

  The upper end of the decorative ring may be located above the upper end of the fastening ring, and the engaging portion may be a notch groove that is recessed downward from the upper end of the fastening ring. In this case, the notch groove that is the engaging portion is hidden inside the decorative ring. Therefore, access to the notch groove other than the detachable tool is limited. As a result, it is possible to prevent the fastening ring from being manually attached and detached and unexpected loosening of the fastening ring.

  The outer peripheral surface of the decorative ring may have an upward convex spherical shape. In this case, even if hot water, detergent, tableware stains, or the like adhere to the outer surface of the decorative ring, it tends to flow down from the outer surface of the decorative ring. Therefore, it becomes easy to keep the faucet device clean.

  The decorative ring may include a covering portion that covers the upper edge of the main pipe. In this case, even if hot water, detergent, tableware stains, etc. adhere to the outer surface of the decorative ring, they will not easily enter the main body from between the decorative ring and the upper edge of the main pipe. It is hard to collect on the edge. Therefore, it becomes easier to keep the faucet device clean.

  The main body may further include a resin spacer disposed between the inner peripheral surface of the main tube and the outer peripheral surface of the housing, and the spacer may maintain a state where the main tube and the housing are separated from each other. In this case, since they do not contact with each other, the occurrence of corrosion between the metal on the surface of the main pipe and the metal on the surface of the cartridge can be suppressed.

  The fastening ring and the decorative ring are separated from each other in a state where the distal end member is disposed on the distal end side of the main pipe. In the extending direction of the main pipe, the separation distance between the fastening ring and the decorative ring is the lower end of the fastening ring and the spacer. The lower end of the fastening ring may be positioned below the lower end of the decorative ring so as to be larger than the separation distance. In this case, even if the main body is pushed upward with respect to the cartridge, the spacer contacts the lower end edge of the fastening ring before the fastening ring and the decorative ring contact. Therefore, even if the main body moves up and down, the decorative ring can be prevented from being detached from the fastening ring.

  The fastening ring is a molded body of a thermoplastic resin, and the main tube, the decorative ring, and the housing may be a molded member in which metal plating is applied to the surface of the molded body of the thermoplastic resin, or may be made of metal.

  According to the faucet device according to the present disclosure, it is possible to realize excellent hygiene and simple and inexpensive replacement of the cartridge.
