JP 2003-135301 A

  By the way, in the faucet device that discharges water according to Patent Document 1, the scattered water enters the display, or the humidity in the display becomes high and the display is dewed. There is a risk that the information regarding the discharged water will be difficult to see.

  Then, this invention makes it a subject to propose the faucet device with which the display part on which the information regarding water discharge is displayed is easy to visually recognize.

  In order to solve the above problems, a water faucet device according to the present invention includes an electric valve that adjusts water discharge, a case that houses the electric valve, an operation surface that is provided in the case and operates the electric valve, , Provided on a part of the operation surface, for displaying information on water discharge, a waterproof sheet covering the entire operation surface and having translucency, and covering the waterproof sheet and having translucency A cover body, a frame-shaped waterproof member that is provided between the waterproof sheet and the cover body and is positioned so as to surround the display unit, and in a space between the waterproof sheet and the cover body, A non-immersed space surrounded by the waterproof member is provided in a region overlapping with the display unit.

  In the faucet device of the present invention, in the space between the waterproof sheet and the cover body, a non-immersed space surrounded by a frame-shaped waterproof member is provided in a region overlapping with the display unit. Intrusion can be suppressed, and it is possible to suppress the humidity in the region from increasing and condensation in the region. Thereby, the water faucet device of the present invention is such that water is unlikely to exist in an area overlapping with a display unit on which information related to water discharge is displayed, and the display unit is easily visible.

The water faucet device of one embodiment of the present invention is shown, (a) is an exploded perspective view, and (b) is a perspective view of the principal part fractured partially. It is a perspective view which shows the water faucet device same as the above.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  The faucet device 100 of one embodiment of the present invention shown in FIG. 2 is a hot and cold water mixing faucet with a shower head (not shown) attached to the wall surface of the bathroom. In the following, each configuration will be described with the side where the faucet device 100 is located on the wall surface of the bathroom as the front side, the opposite side as the rear side, and the horizontal direction orthogonal to the front-rear direction as the left-right direction. That is, the direction indicated by the arrow X1 in FIG. 2 is the forward direction, the opposite direction is the backward direction, the direction indicated by the arrow Y1 is the right direction, the opposite direction is the left direction, and the direction indicated by the arrow Z1. Is the upward direction, and the opposite direction is the downward direction.

  The faucet device 100 includes an operation unit operated by a user on the front surface thereof. The operation unit is not operated to rotate by a handle or a dial, but is pressed by a tactile switch. The faucet device 100 may further include a valve that is manually operated by a handle.

  As shown in FIGS. 1 (a), 1 (b) and 2, the water faucet device 100 includes a motor-operated valve 1, a case 2, an operation surface 3, a waterproof sheet 4, a waterproof member 8, a cover body 5, and a push button. 6. A drain port 7 and a water discharge port 101 are provided.

  The electric valve 1 is a valve that adjusts water discharge from the water discharge port 101. Specifically, the motor operated valve 1 is a valve that adjusts the amount of water discharged from the water outlet 101, adjusts the temperature of water discharged from the water outlet 101, and adjusts the switching of water discharged from the water outlet 101 and water discharged from the shower head. is there. The motor-operated valve 1 is electrically connected to a control unit housed in the case 2 and is controlled by the control unit.

  The faucet device 100 of the present embodiment has a plurality of motor operated valves 1. The motor-operated valve 1 is a motor-operated valve 1 that constitutes a hot and cold water mixing valve, a motor-operated valve 1 that constitutes a water discharge valve, and a motor-operated valve 1 that constitutes a flow path switching valve. A hot water supply pipe and a water supply pipe are connected to the hot water mixing valve. The hot and cold water mixing valve changes the mixing ratio of the hot water and water that flowed in to generate water discharge at an arbitrary temperature. The water discharge valve switches between water discharge and water stop generated by the hot water mixing valve. Moreover, the valve for water discharge changes the flow volume of water discharge. The flow path switching valve switches between discharging water from the shower head and discharging water from the currant (water outlet 101).

  The case 2 is a synthetic resin box in which the electric valve 1 is housed. As shown in FIG. 1A and FIG. 2, the case 2 includes a case body 20, a top plate 21, a pair of left and right side plates 22, and a piping cover 23. The case body 20 has an upper surface covered with a top plate 21, left and right side surfaces covered with a pair of left and right side plates 22, and a lower portion covered with a pipe cover 23. The piping cover 23 is a cover that covers the hot water supply pipe and the water supply pipe that are piped from the outside (rear side) of the wall surface of the bathroom into the bathroom. The case main body 20 has an upper portion protruding forward, a lower surface of the protruding upper portion is exposed to the outside, and a water discharge port 101 is disposed on the lower surface. The top plate 21 is long in the front-rear direction and can be used as a mounting table.

  Although not shown, the case body 20 houses the control unit that controls the motor-operated valve 1 and a water discharge mechanism that is driven and controlled by the control unit. The water discharge mechanism includes a flow sensor and the plurality of motor-operated valves 1 described above. The water discharge mechanism is connected to the flow rate sensor, the hot water mixing valve, the water discharge valve, and the flow path switching valve in this order from the upstream side through a pipe. For example, the control unit controls the water discharge valve based on a flow rate value input from the flow rate sensor. The motor-operated valve 1 that forms a valve for water discharge is constituted by, for example, an electromagnetic valve.

  When the operation unit is operated by a user and a signal is input from the operation unit, the control unit outputs a control signal to the water discharge mechanism unit, thereby controlling the water discharge mechanism unit. The control unit includes, for example, a microprocessor mounted on a control board as a main component.

  The operation surface 3 is provided on a part of the outer surface of the case 2 and is a portion for operating the motor-operated valve 1. The operation surface 3 is provided so as to operate the electric valve 1 by being pressed by the push button 6 through the cover body 5 and the waterproof sheet 4.

  The operation surface 3 is constituted by the front surface of the upper portion from which the case body 20 protrudes. A waterproof sheet 4, a waterproof member 8, a cover body 5, and a push button 6 are attached to the operation surface 3 in this order.
