A water discharge switch 28 for manually discharging water is provided on the upper surface of the head 24.

As shown in FIG. 3, the operation panel 16 includes:
In addition to the water discharge switch 30, temperature control switches 32 and 34 for changing the temperature of the mixed water, a mixed water switch 36 for discharging the mixed water, a water switch 38 for directly discharging the water from the water supply pipe, A hot water switch 40 for directly discharging hot water from the hot water supply pipe is provided.

Further, the operation panel 16 is provided with a weighing switch 42 for performing a weighing operation which will be described later. Then, on the operation panel 16, the switch 32,
A display panel 44 is provided for displaying the target discharge temperature of the mixed water selected in step 34 and for displaying the weighing result.

The weighing mechanism of the faucet will be described with reference to FIGS. 1 and 2.

The water discharge switch 28 is provided with a piezoelectric element 48 which is pushed via a pressure receiving piece 46. Reference numeral 50 is a cover made of soft synthetic resin for covering the pressure receiving piece 46. When the pressure receiving piece 46 is pushed from above the cover 50, the piezoelectric element 48 outputs a voltage and the water discharge signal is transmitted to the control circuit 52 (see FIG. 5).
Is input to switch between water discharge and water stoppage.

In order to use this piezoelectric element 48 as a load sensor for weighing, a weighing dish 54 can be mounted on the upper surface of the head 24. That is, the groove 56 is provided in the upper surface portion of the head 24, and the stay portion 60 of the holder 58 is provided.
Can be fitted into the groove 56. The holder 58 is provided with a cylindrical guide portion 62, and the columnar leg portion 64 of the weighing dish 54 is slidably fitted in the guide portion 62. The lower end of the leg 64 is the cover 50.

When seasoning is placed on the upper surface of 4, the load is
6 is transmitted to the piezoelectric element 48, and the piezoelectric element 48 outputs a voltage having a magnitude corresponding to the weight of the seasoning placed on the upper surface of the weighing dish 54.

The load detection signal of the piezoelectric element 48 is input to the control circuit 52, and this voltage is converted into weight. The converted weight is displayed on the display panel 44.

As shown in FIG. 3, the display panel 44 is provided with a water temperature symbol of ° C and a weight symbol of g. When the weighing switch 42 is pressed, the g symbol is displayed. When the weighing switch 42 is turned off, the ° C symbol is displayed.

A mixing valve 70 is provided in the cabinet 10 and a hot water supply pipe 72 and a water supply pipe 74 are connected thereto. The mixed water discharge port of the mixing valve 70 is connected to the faucet body 14 via a pipe 76. In the present embodiment, bypass pipes 78 and 80 are branched from the water supply pipe 74 and the hot water supply pipe 72, so that water from the water supply pipe and hot water from the hot water supply pipe can be directly supplied to the faucet body 14. I am trying. Solenoid valves 82, 8 are provided on the pipes 76, 78, 80, respectively.

86 is opened / closed by a control signal from the control circuit 52.

In the water faucet thus constructed, when the weighing switch 42 is turned off, it can be used in the same manner as a normal automatic water faucet. That is, by operating the water discharge switches 28 and 30, it is possible to switch between water discharge and water stoppage. When the user extends his / her hand below the water spout 22, the sensor 26 senses this and the automatic water spouting is performed. Further, as described above, when the switches 38 and 40 are pressed, water or hot water from the water supply pipe or the hot water supply pipe is directly discharged. By operating the temperature adjusting switches 32 and 34, the temperature of the mixed water can be set to a desired temperature.

When the weighing switch 42 is pressed, the weighing function operates as described above, the seasoning and the like placed on the weighing dish 54 are weighed, and the result can be displayed on the display panel 44. .

Thus, according to the water faucet of this embodiment,
It has not only an automatic faucet function but also a weighing function,
You can measure seasonings without installing a scale in the kitchen. Moreover, in the present embodiment, the piezoelectric element 48 of the water discharge switch 28 is also used as a load sensor for load detection, and the number of electric components can be reduced. Further, since the weighing dish 54 is provided at the tip portion of the water discharge pipe 20 and is located near the user, it is possible to easily place even a small amount of seasoning on the weighing dish 54.

[0020]

As described above, the faucet of the present invention has a weighing function in addition to the water discharge function, and it is possible to weigh seasonings and the like without installing a scale in the kitchen.
