In addition, in the above-described embodiment, the case in which the absorption filter 300 completely covers the outer surface of the heater 118 is described as an example, but the absorption filter 300 surrounds a part of the outer surface of the heater 118. It is also possible to configure the system to be installed. That is, it is also possible that the absorption filter 300 to cover only a part of the outer surface of the heater 118 near the steam discharge pipe 116.

In the steam generator of the cleaner according to the present invention as described above, the heater is formed in the left and right long, the absorption filter is wrapped around the outer peripheral surface of the heater. Therefore, since the water contained in the absorption filter is heated by the heater, there is an advantage that the steam generation time is reduced. That is, even when the water inside the steam generator is not heated, only the water permeated into the absorption filter in contact with the heater outer circumferential surface of the steam is generated first, so the steam generation time at the first start is shortened.

In addition, in the present invention, since the absorption filter is configured to surround the heater as a whole, there is an effect that the phenomenon of leakage of water inside the steam generator to the outside through the steam discharge pipe is prevented. That is, when the absorption filter does not surround the heater, the water heated by the heater is boiled and bubbles are generated, and these bubbles are gradually enlarged in layers to reach the top of the steam discharge pipe, and subsequently flow out through the steam discharge pipe. Will be. However, in the present invention, since the absorption filter surrounds the heater, the generation of bubbles is suppressed. Therefore, there is an effect that the shape of the water discharged to the outside through the steam discharge pipe is prevented.

In addition, in the present invention, the absorption filter is firmly fixed inside the steam generator by the filter fixing means and the fixing rib.
