[0030]

As described above, according to the present invention, the connecting member for guiding the water dropped from the dropping hole of the tank to the vaporizing chamber is formed of a flexible rubber, and the dropping chamber and the vaporizing chamber provided immediately below the dropping hole are provided. Is formed, and the water in the pump is sent to the vaporization chamber by pressing the pump chamber. Therefore, vaporization is faster than that in which low-temperature water in the tank is directly sent to the vaporization chamber. No hot water is blown out.

Even if the pump chamber is operated many times when the temperature of the vaporization chamber is low enough to generate steam, the amount of water previously stored in the pump chamber is small, so that the water enters the vaporization chamber continuously. No water droplets adhere to clothing without being.

Further, since the communication member is formed by superimposing the upper rubber structure and the lower rubber structure, and the lower rubber structure is engaged with the upper surface of the base, the communication member can be unitized. As it is easy to handle and can be engaged by its elasticity, making use of the characteristics of the rubber material, it can be engaged not only in positioning but also in a stable position, and
The nature of rubber constitutes part of the pump device and eliminates the need for watertight treatment.

Further, since the arm plate is provided between the drip chamber and the pump chamber, the amount of backflow to the drip chamber side when the pump device is operated can be minimized. When steam is generated, water is not sent to the vaporization chamber at a stretch, so that the water flow is not stopped by the damper plate.
