Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a faucet installed in a kitchen sink or a washbasin, and particularly to a battery-operated faucet.

[0002]

[Prior art]

 Some automatic faucets that detect hands and automatically spout water are powered by dry batteries. By using a battery as a power source, it is not necessary to connect the faucet to a commercial power source, which facilitates the installation and installation of the faucet.

In a conventional battery-operated faucet, a battery box for accommodating dry batteries is provided on the body side of the faucet, and the battery box is covered with a lid.

[0004]

[Problems to be solved by the device]

 In such a conventional battery-operated water faucet, the battery replacement port is arranged on the upper surface or the side surface of the water faucet, and the lid is conspicuous. Also, since the faucet has a battery replacement port on the top and side surfaces, it is necessary to make the lid seal strict to prevent water from entering the inside. The cost was high.

[0005]

[Means for Solving the Problems]

 The faucet according to claim 1, wherein the faucet has a faucet body having a battery exchange port and a lid covering the battery exchange port, a battery box is provided on the back side of the lid, and the faucet body side and the lid side are provided. In addition, a power extraction electrode and a power feeding electrode, which are in contact with each other when the lid is closed, are provided.

According to a second aspect of the invention, in the first aspect of the invention, the battery exchange port is provided on a downward surface portion of the water faucet.

A water faucet according to a third aspect is the water faucet according to the first or second aspect, wherein the power supply electrode is provided only on opposite side surfaces of the battery box.

[0008]

[Action]

 In the faucet of the present invention, the lid is provided with the battery box. Therefore, when the lid is removed from the faucet body, the battery box together with the lid is taken out of the faucet. Therefore, even if a battery exchange port is provided on the downward surface of the faucet as in claim 2, the battery can be taken in and out of the battery box at a place other than the faucet, which is extremely convenient.

In the water faucet according to the second aspect, since the battery exchange port is on the downward surface of the water faucet, it is possible to reliably prevent water from entering the inside of the battery box through the battery exchange port.

In the water faucet according to claim 3, even when the lid is removed and placed on a metal plate (for example, a stainless steel plate on the upper surface of the kitchen cooktop), the postures of the lid and the battery box are set in any manner. However, the power supply electrodes do not short-circuit via the metal plate.

As shown in FIG. 2, the water faucet of this embodiment is of a deck type which is attached to the washbasin 2 or the like. The main body 1 of the faucet has a substantially L-shape in a side view, which is composed of a faucet trunk portion 3 and a horizontal extension portion 4 extending from the faucet trunk portion 3 to the front side. The surface of the faucet body 1 is composed of an upper cover 5 that covers the upper part of the faucet and a lower cover 6 that covers the lower part of the faucet. All of these covers 5 and 6 are made of synthetic resin.

The faucet body 1 is designed to automatically open and close a valve by a built-in battery 7, and as shown in FIG. 1, a battery replacement port 8 is provided near the center of the horizontal portion of the lower cover 6. Is provided. A battery box 9 accommodating the battery 7 is attached to the battery exchange port 8, and the lower surface of the battery box 9 serves as a lid 10 that covers the opening of the battery exchange port 8.

As shown in FIG. 3, a water pipe 11 is housed inside the faucet body 1. One end of the water supply pipe 11 is connected to the solenoid valve 12. The solenoid valve 12 is connected via a lead wire 20 to a circuit board 19 arranged in the faucet trunk portion 3, and the solenoid valve 12 is connected to a pipe joint protruding from a lower end surface of the faucet trunk portion 3. The part 13 is connected. The other end of the water supply pipe 11 is connected to a water discharge port 14 provided on the lower surface of the front part of the lower cover 6.

The upper cover 5 is fixedly attached to the lower cover 6 with a screw 16. In front of the water outlet 14 provided on the lower cover 6, there is provided a sensor 21 for detecting an object such as a hand or a cup that is extended below the water outlet 14. The sensor 21 is composed of an infrared light emitting element 21A and an infrared light receiving element 21B (FIG. 1), and is connected to the circuit board 19 via lead wires. The battery box 9 is also connected to the circuit board 19 via lead wires.

As shown in FIG. 5, the battery box 9 has a substantially rectangular parallelepiped container shape. At the edge of the lid 10 on the lower surface of the battery box 9, a claw 22 for locking the lid 10 to the edge of the battery exchange port 8 is provided. Further, a tool hooking portion 23 used when removing the lid 10 from the battery exchange port 8 is provided at an edge portion of the lid 10.

A concave groove 24 is provided on the side surface of the lid 10 over the entire circumference, and a packing 25 (FIGS. 3 and 4) is attached to the concave groove 24.
