Description

  The present invention relates to a humidifier including a liquid heating body that heats a liquid such as water.

  2. Description of the Related Art Conventionally, a liquid heating body that heats a liquid such as water and atomizes the liquid is attached to a device such as a humidifier. As shown in FIG. 6 or FIG. 8, such a liquid heating body normally presses a concave liquid heating body 81 from below to a part 80a of the casing 80 via a packing 82, and a plurality of screws 83a, 83b, 83c, 83d, 83e, 83f were fixedly attached. Also, a heater 84 for heating the liquid heating body 81, a thermostat 85 for controlling the temperature of the liquid heating body 81, or for shutting off the power supply from the power source when an abnormal current flows in the electric circuit Electrical components such as the thermal fuse 86 are attached in a state of being exposed on the lower surface of the liquid heating body 81 (for example, JP-A-11-63588 or JP-A-2000-104959).

However, in the structure in which the liquid heating body 81 is pressed and fixed from below, it is necessary to fix the liquid heating body 81 with a large number of screws 83a, 83b, 83c, 83d, 83e, and 83f so that the liquid heating body 81 does not fall. A large number of 87a, 87b, 87c, 87d, 87e, and 87f are required, the structure of the liquid heating element 81 is complicated, the mounting work is extremely complicated, and uniform screw tightening is difficult, and the mounting state tends to be unstable. was there.
As shown in FIG. 8, the upper end opening of the liquid heating body 81 is fixed to a part 80 a of the casing via the packing 82, but the heat of the metal liquid heating body 81 and the resin packing 82 Water or the like may leak out of the liquid heating body 81 due to a difference in expansion rate or deterioration of the packing 82 over time, and the leaked water or the like travels along the outer surface of the liquid heating body 81 to reach the lower surface. There was a risk of damaging or igniting electrical components attached to the bottom surface.
