Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 3 show a hot air outlet of an air towel for automatically blowing out hot air by the operation of an electric heater and a blower near the water outlet on the side where the water outlet of the water discharge pipe is located. A first embodiment of the present invention in which an infrared sensor for sensing the hand when the hand is approached and operating the electric heater and the blower is provided on the side of the water discharge pipe opposite to the side where the water discharge port is located. Is shown. In this embodiment, as the faucet, a water / water mixer tap that switches between water discharge and water stoppage by using an operation handle provided on the water / water mixer tap main body is adopted, but a single faucet may be used.

In FIG. 1 to FIG. 3, reference numeral 1 denotes a hot-water mixing tap installed on, for example, a kitchen sink 2, which is operated to operate a hot-water inlet, a water inlet, and a hot-water-mixed water outlet 14 by operating an operation handle 3. The hot water mixing chamber (not shown) provided in the hot water mixing tap main body 4 has a configuration in which hot water is mixed at an appropriate ratio to discharge desired hot water.

[0008] That is, provided in the hot and cold water mixing tap body 4,
For example, a fixed valve 6 fixed to the bottom of the case 5a of the cartridge 5 in a watertight state is provided with a mixture of water flowing through the water flow path 8 from the water supply pipe 7 and hot water flowing through the water flow path 10 from the hot water supply pipe 9. A movable valve element 11 for adjusting the ratio is slidably mounted on the movable valve element 11 in a watertight manner, a disc guide 12 is mounted on the movable valve element 11, and an operation lever 3 a mounted on a lower end side of the operation handle 3. The lower end is interlocked with the movable valve element 11, and the movable valve element 11 is rotated by the disk guide 12 by operating the operation handle 3 in the left and right directions.
Hot water and water flow into the internal flow path, and the hot and cold mixed water discharge flow path 13
The water is discharged from a water discharge port 16 to be described later through the outlet port 14 of. Further, by operating the operation handle 3 in the vertical direction indicated by the double-headed arrow A, the flow rate adjustment including the water stoppage is performed.

Reference numeral 18 denotes a water discharge pipe having a water discharge port 16 at the tip, which is connected to the outlet 14 of the hot and cold water mixing tap 1.
In this embodiment, the heat-insulating cap 1
The water outlet 16 is formed on the lower surface m of the heat insulating cap 17. Reference numeral 15 denotes a spout cover. The symbols r and i are the heat insulating cap 1
7 are both side surfaces.

Reference numeral 19 denotes a dryer-type air towel.
A power cord 22, an air towel body 20 containing a blower and a motor for driving the blower on the side of the power cord 22, and an electric heater on the side of a hot air guide tube 23 to be described later, and the inside of the hot / water mixing tap body 4 from the air towel body 20. Hot air blow-out chamber 23 of heat insulation cap 17 through water discharge pipe cover 15
a, and a hot air outlet 24 provided in the hot air outlet chamber 23a. This hot air outlet 24
Is provided on the lower surface m of the heat insulating cap 17 and further on the distal end side than the water discharge port 16.

Reference numeral 25 denotes an infrared sensor for detecting an approach of a hand and operating the electric heater and the blower by detecting the hand. This infrared sensor 25 is provided on the upper surface n side of the heat insulating cap 17 opposite to the lower surface m side of the heat insulating cap 17 where the water discharge port 16 is located.

The infrared sensor 25 automatically stops the electric heater and the blower when the electric heater and the blower are operated and the hand does not approach the infrared sensor 25 again for a predetermined time (for example, about 1 minute). The function of activating or automatically stopping the electric heater and blower is as follows:
This is performed by microcomputer control. 40 is an infrared sensor 2
5 is a lead wire connecting the microcomputer and the water discharge pipe cover 15.
It is installed in.

Then, the operation handle 3 is raised upward, for example, and a dishwashing or the like is performed from the spout port 16 while the hot and cold water H or hot water or water is spouted. Then, the operation handle 3 is lowered downward. And stop the water. Subsequently, the infrared sensor 25
When the hand is approached, the electric heater and the blower are operated and the hot air B is blown from the hot air outlet 24 to dry the hand. Also, if the hand approaches the infrared sensor 25 again within one minute after the hot air B is blown out, the operation of the electric heater and the blower can be stopped.

On the other hand, if the electric heater and the blower are operated and the hand does not approach the infrared sensor 25 again for more than one minute while being operated, the electric heater and the blower are automatically stopped.

FIG. 4 shows an infrared sensor 25 for detecting when a hand is approached and operating an electric heater and a blower.
Is shown on the lower surface m side of the heat insulating cap 17 where the water discharge port 16 is located, according to a second embodiment of the present invention. FIG.
, The same components as those shown in FIGS. 1 to 3 are the same or equivalent.

In this embodiment, the infrared sensor 25 is
Although located upstream of the water outlet 16, it may be downstream.

Also in this embodiment, after washing dishes, the operation handle 3 is lowered to stop water. continue,
When the hand is brought close to the infrared sensor 25 provided on the same side as the water outlet 16, it is sensed and the electric heater and the blower operate,
Hot air can be blown from the hot air outlet 24 to dry the hand. Also, if the hand approaches the infrared sensor 25 again within one minute after the hot air is blown out, the operation of the electric heater and the blower can be stopped. Further, when the electric heater and the blower are operated and the hand does not approach the infrared sensor 25 again for more than one minute, the electric heater and the blower are automatically stopped.

FIG. 5 shows an infrared sensor 25 and a hot air outlet 24 connected to a water discharge pipe 15 of a hot water mixing tap 31 of a wash basin 30.
9 shows a third embodiment of the present invention provided on the upper surface n side and the lower surface m side of the heat insulating cap 17 in FIG. In FIG. 5, the same components as those shown in FIGS. 1 to 4 are the same or equivalent.

Also in this embodiment, if the hand is again brought closer to the infrared sensor 25 within one minute after the hand is washed, the operation of the electric heater and the blower can be stopped.

Also in this embodiment, the infrared sensor 25 may be provided on the lower surface m of the heat insulating cap 17 where the water outlet 16 is located.

In the present invention, the infrared sensor 25 is connected to both sides r, i of the heat insulating cap 17 where the water outlet 16 is located.
May be provided in any one of the above.

In the present invention, the operation lever 3 is of a single lever type. However, the operation handle 3 is not operated up and down, left and right as in the case of a single lever type.
A rotary type that can be rotated to switch between water discharge and water stoppage can also be used.

[0023]

According to the present invention, hot water is automatically generated by the operation of the electric heater and the blower near the water discharge port on the side where the water discharge port of the water discharge pipe of the water faucet is switched by the operation handle. Since a hot air outlet of an air towel for blowing out and drying hands is provided, and an infrared sensor for detecting an approach of a hand and operating an electric heater and a blower is provided at or near the water discharge pipe, for example, a washing surface On a table, drying can be performed from a hand-washing operation in one place (in a washbasin), or, for example, in a sink, drying can be performed from a washing operation on tableware in a single place (in a sink), Only the inside of the washbasin or the sink is soiled, and there is no possibility that the surrounding floor and the like will be soiled. Also, no space for installing an air towel is required.
