Abstract

Provided is a faucet device for an aircraft lavatory unit, wherein a second joint and a third joint are joined by inserting the third joint of a heater module into a second joint of a valve module, and screw members are used to fasten a first case and a second case. As a result, the valve module and the heater module are joined in series via the second joint and the third joint. A first connector of a controller module is joined to a third connector of the valve module and a second connector of the controller module is joined to a fourth connector of the heater module. The first joint of the valve module is joined to a water supply pipe. A fourth joint of the heater module and a faucet main body are joined via a pipe.

First claim

1 . A faucet device for an aircraft lavatory unit comprising:
a water supply channel that connects a water supply pipe and a faucet main body; a water supply valve disposed in the water supply channel; a heater for heating water supplied from the water supply channel; and a controller for performing control of an opening and closing operation of the water supply valve and a heating operation of the heater, the faucet device for the aircraft lavatory unit further comprising: a valve module and a heater module that are disposed in series in a section of the water supply channel, the valve module including a first case, a first joint that is provided in a surface of the first case and is removably joined to the water supply channel, a second joint that is provided in the surface of the first case at a different location from that of the first joint, and a water supply valve that is integrated in the first case and connects the first joint and the second joint, and the heater module including a second case, a third joint that is provided in a surface of the second case and is removably joined to the second joint, a fourth joint that is provided in the surface of the second case at a different location from that of the third joint and removably joined to the water supply channel, a water channel for heating that is integrated in the second case and connects the third joint and the fourth joint, and the heater that is integrated in the second case and heats water flowing in the water channel for heating.

2 . The faucet device for the aircraft lavatory unit according to claim 1 , wherein in a state in which the valve module and the heater module are joined in series via the second joint and the third joint, a portion of the first case in which the second joint is provided and a portion of the second case in which the third joint is provided abut against each other, and
screw members are provided that fasten the first case and the second case in a direction that causes the portions of the first and second cases to abut against each other.

3 . The faucet device for the aircraft lavatory unit according to claim 1 , wherein in a state in which the valve module and the heater module are joined in series via the second joint and the third joint, a holding member is provided on which the first case and the second case are separately mounted and which holds the first case and the second case.

4 . The faucet device for the aircraft lavatory unit according to claim 1 , wherein the second joint and the third joint are removably joined and are configured by including a holding member that holds a state in which the second joint and the third joint are joined.

5 . The faucet device for the aircraft lavatory unit according to claim 1 , further comprising: a first connector that outputs a first control signal from the controller to the valve module; a second connector that outputs a second control signal from the controller to the heater module; and a controller module that is integrated into a third case, wherein
a third connector that is removably joined to the first connector is integrated into the first case, and a fourth connector that is removably joined to the second connector is integrated into the second case.

6 . The faucet device for the aircraft lavatory unit according to claim 1 , further comprising: a water purification module that is disposed in a section of the water supply channel and in series with the valve module and the heater module, wherein
the water purification module includes a fourth case, two fifth and sixth joints that are provided in a surface of the fourth case at different locations from each other and are removably joined to the water supply channel or any one of the first to fourth joints, a water purification water channel that is integrated into the fourth case and connects the fifth joint and sixth joint, and water purifier that is integrated into the fourth case and purifies water flowing in the water purification water channel.

7 . The faucet device for the aircraft lavatory unit according to claim 6 , wherein in a state in which the valve module, the heater module, and the water purification module are joined in series via the joints, portions of the cases in which the joints are located abut against one another, the joints being joined together while joining adjacent modules, and
screw members are provided that fasten the cases in a direction that causes the portions of the cases to abut against one another.

8 . The faucet device for the aircraft lavatory unit according to claim 6 , wherein in a state in which the valve module, the heater module, and the water purification module are joined in series via the joints, a holding member is provided on which the first case, the second case, and the fourth case are separately mounted and which holds the first case, the second case, and the fourth case.

9 . The faucet device for the aircraft lavatory unit according to claim 6 , wherein the joints that join the valve module, the heater module, and the water purification module are configured by including a holding member that causes the joints to be removably joined and holds a state in which the joints are joined.

10 . The faucet device for the aircraft lavatory unit according to claim 2 , further comprising: a first connector that outputs a first control signal from the controller to the valve module; a second connector that outputs a second control signal from the controller to the heater module; and a controller module that is integrated into a third case, wherein
a third connector that is removably joined to the first connector is integrated into the first case, and a fourth connector that is removably joined to the second connector is integrated into the second case.

11 . The faucet device for the aircraft lavatory unit according to any claim 2 , further comprising: a water purification module that is disposed in a section of the water supply channel and in series with the valve module and the heater module, wherein
the water purification module includes a fourth case, two fifth and sixth joints that are provided in a surface of the fourth case at different locations from each other and are removably joined to the water supply channel or any one of the first to fourth joints, a water purification water channel that is integrated into the fourth case and connects the fifth joint and sixth joint, and water purifier that is integrated into the fourth case and purifies water flowing in the water purification water channel.

12 . The faucet device for the aircraft lavatory unit according to claim 11 , wherein in a state in which the valve module, the heater module, and the water purification module are joined in series via the joints, portions of the cases in which the joints are located abut against one another, the joints being joined together while joining adjacent modules, and
