  FIG. 6 is a partially cutaway cross-sectional view showing the structure of the instantaneous heating device 33. In FIG. 6, the instantaneous heating device 33 includes a casing 504, a sheathed heater 505, a heat conductor 506, a pipe 510, a thermistor 33a, a thermostat 33b, and a thermal fuse 33c.
[0072]
  The casing 504 has a substantially rectangular parallelepiped shape. In the casing 504, a pipe 510 and a sheathed heater 505 are provided with a predetermined interval so as to extend in the longitudinal direction, and both end portions of the casing 504 protrude from the both end surfaces to the outside.
[0073]
  In the casing 504, the pipe 510 and the sheathed heater 505 are covered with a heat conductor 506. The sheathed heater 505 has a built-in heating wire and generates heat when electric power is supplied.
[0074]
  During the nozzle cleaning described above, the cleaning water supplied from the cleaning water outlet 143e of the switching valve 14 in FIG. 3 is introduced into the pipe 510 from the water supply port 511.
[0075]
  When electric power is supplied to the sheathed heater 505, heat generated by the sheathed heater 505 is transmitted to the pipe 510 through the heat conductor 506. As a result, the cleaning water introduced into the pipe 510 is heated, and the high temperature water for nozzle cleaning or the water vapor for nozzle cleaning is discharged from the discharge port 512.
[0076]
  Here, in FIG. 6, when the water supply port 511 side of the pipe 510 is the upstream side of the instantaneous heating device 33 and the discharge port 512 side is the downstream side of the instantaneous heating device 33, the thermistor 33 a and the thermostat 33 b are downstream of the instantaneous heating device 33. On the side. Further, the thermal fuse 33 c is provided on the side surface of the casing 504.
[0077]
  In this embodiment, the thermistor 33a, the thermostat 33b, and the thermal fuse 33c have different operation reference temperatures. Thereby, adjustment of overheating prevention of three steps can be performed. Furthermore, even if any one of the thermistor 33a, the thermostat 33b, and the thermal fuse 33c fails, the remaining two prevent overheating.
[0078]
  The thermistor 33 a is attached to the sheathed heater 505 and detects the temperature of the sheathed heater 505. The control unit 4 determines the temperature of the sheathed heater 505 supplied from the thermistor 33a, and performs control so as to lower the temperature of the sheathed heater 505 when it is in an overheated state.
[0079]
  The thermostat 33b is attached so that the temperature of the washing water flowing through the pipe 510 can be detected. When the temperature of the cleaning water flowing through the pipe 510 exceeds the operation reference temperature of the thermostat 33b, the thermostat 33b operates to cut off the power supply of the sheathed heater 505.
[0080]
  Finally, the thermal fuse 33c is tightly fixed to the casing 504. When the temperature of the casing 504 exceeds the operation reference temperature of the thermal fuse 33c, the supply of electric power to the sheathed heater 505 is interrupted by blowing the thermal fuse 33c.
[0081]
  The above-described functions of the thermistor 33a, thermostat 33b, and thermal fuse 33c prevent overheating of cleaning water by the sheathed heater 505 and overheating of the sheathed heater 505 itself.
[0082]
