That is, the hot water pipe is provided, and the hot water pipe forms a residual heat circuit for the wind passing through the ventilation duct.

The second gist is that a hot air outlet capable of blowing warm air for drying a hand is connected to a ventilation duct equipped with a fan, and hot water is passed through the ventilation duct. That is, a pipe is provided, and the hot water pipe forms a residual heat circuit for the wind passing through the ventilation pipe.

(Operation) In the first aspect, since the residual heat circuit formed of the hot water pipes is arranged in the ventilation duct, the wind passing through the ventilation duct in the residual heat circuit is in the initial stage. By receiving heat from the warm water, it becomes good warm air, and good warm air can be blown out from the warm air outlet from the initial stage.

Further, in the second aspect, since the residual heat circuit formed by the hot water pipe is arranged in the ventilation duct, the wind passing through the ventilation duct is the hot water in the residual heat circuit at the initial stage. The heat from the hot air blows into a good warm air, and a good warm air can be blown out from the warm air blowout port from the initial stage, and the function of the warm air blowout device is improved.

That is, when a hand is held in front of the detection sensor 7a, the detection sensor 7a discharges the water soap from the water soap discharge nozzle 4 to the bowl portion 3a side, and in front of the detection sensor 7b. When the user holds his or her hand, hot water is ejected from the hot water outlet 5, and when the hand is held in front of the detection sensor 7c, warm air is blown out from the hot water outlet 6. Display windows 8a, 8b, 8c are provided above the water soap discharge nozzle 4, the hot water outlet 5, and the hot air outlet 6, respectively, so that their operating states can be displayed.

A water soap tank 9 is connected to the water soap discharge nozzle 4 via a pipe or the like, a pump 9a is provided on a side of the water soap tank 9, and a water soap tank is provided on an upper portion of the water soap tank 9. An inlet 9b is provided, and this water soap inlet 9b
From b, the water soap can be replenished in the water soap tank 9.

A hot water pipe 10 is connected to the hot water discharge port 5, a downstream end of the hot water pipe 10 is connected to a mixing thermo 11, and a hot water pipe 12 for passing hot water and a water The water pipe 13 through which the water passes
The hot water introduced through the water pipe 13 and the hot water pipe 13 can be mixed in the mixing thermostat 11 at an appropriate temperature and can be ejected from the hot water outlet 5 through the hot water pipe 10. Further, the mixing thermo 11 is provided with a temperature control handle 11 a for adjusting the temperature of hot water supplied to the hot water pipe 10.

A ventilation duct 14 is connected to the warm air outlet 6, a fan 15 is provided at the lower end of the ventilation duct 14, and a ventilation duct 14 upstream of the fan 15 is provided.
A heater 16 is disposed inside, and when the fan 15 is operated based on the detection signal of the detection sensor 7c, the heater 16 heats the wind to generate warm air, and the ventilation duct 1
The hot air is blown out from the hot air outlet 6 through the nozzle 4.

In this example, a part of the hot water pipe 10 is formed in a coil shape, and the coiled portion is piped in the ventilation duct 14, and the coiled portion forms a residual heat circuit 10a. Is formed. That is, since warm water passes through the residual heat circuit 10a, the warm water tries to warm the air flowing through the ventilation duct 14, and the warm air is satisfactorily preheated before the effect of the heater 16 appears and the initial temperature is increased. From the stage, an attempt is made to eject good warm air from the warm air outlet 6.

Incidentally, FIG. 3 shows a modification of the washbasin in a plan view.

That is, in the case of FIG. 3, the right end portion of the back wall portion 3b of the washbasin 3 is bent to the side of the bowl portion 3a to form a substantially L-shaped back wall portion 3b. The hot water outlet 6 is provided in the bent side bent portion 3ba of the back wall portion 3b, and the hot water outlet 6 is arranged on the side edge side of the bowl portion 3a.

With this configuration, the warm air blown out from the warm air outlet 6 is blown out from the side surface side of the bowl portion 3a, so that the warm air outlet 6 can be satisfactorily heated from the warm air outlet 6 without malfunction. The hand can be dried well by blowing out the wind. That is, since the hot air outlet 6 is provided in the bent portion 3ba, the detection sensor 7c also has the bent portion 3b.
Since the detection sensor 7a and 7b and the detection sensor 7c become longer, the detection sensor is provided even if the hand is moved when the warm air is blown from the warm air outlet 6 to dry the hand. Since 7a or 7b does not operate, the risk of malfunction is better avoided.

Incidentally, in FIG. 1, the detection sensors 7a, 7b, 7c
Have a height difference in their installation heights, and if they have a considerable height difference, the detection sensors 7a, 7b, 7c will not operate at the same time even when the hand is moved horizontally. It is possible to satisfactorily avoid the malfunction as in the past.

4 and 5 show modified examples of the residual heat circuit in the ventilation duct 14.

That is, in the case of FIG. 4, the hot water pipe 12 for passing hot water in the ventilation duct 14 is formed into a coil shape, and the residual heat circuit 12a is formed in this coiled portion. In this case, since the hot water pipe 12 through which the hot water passes is directly provided in the ventilation duct 14, a better residual heat function is exhibited,
The warm air can be ejected from the warm air outlet 6 better than in the initial stage.

In the case of FIG. 5, the downstream side of the fan 15 (suction side)
In this case, the hot water pipe 12 is connected to the hot water pipe 12, and the residual heat circuit 12a is formed by the hot water pipe in the ventilation duct 14. In this case as well, the temperature of the hot water passing through the residual heat circuit 12a before the heater 16 exerts its effect. As a result, it is possible to satisfactorily warm the wind that passes through the ventilation duct 14 and blow good warm air from the warm air outlet 6.

(Effect of the Invention) In the present invention, a ventilation duct equipped with a fan is connected to a warm air outlet capable of ejecting warm air for drying a hand, and hot water is introduced into the ventilation duct. The hot water pipe that passes through is provided, and the hot water pipe forms a residual heat circuit for the wind that passes through the ventilation duct, so that the wind that passes through the ventilation duct will generate heat from the hot water in the residual heat circuit at the initial stage. As a result, the hot air becomes good, and it is possible to blow out good hot air from the hot air outlet from the initial stage.

In addition, since a hot water pipe for arranging hot water is provided in the hot air outlet in the ventilation pipe line provided with the fan, and the hot water pipe forms a residual heat circuit for the wind that passes through the ventilation pipe line, The wind passing through the pipe receives heat from the hot water in this residual heat circuit and becomes a good warm air,
