Description

  The present invention relates to a steam cleaner that jets steam to remove dirt.

  When cleaning dirt on the floor corners or accumulated for many years in cleaning work, steam is generated in a steam cleaner, and steam is sprayed onto the dirt to achieve cleaning and disinfection sterilization effects. Most conventional steam cleaners generate water vapor by heating water with a boiler, and the generated water vapor is transported through a heat-resistant conduit and sprayed from a brush.

Water in the aquarium is poured into the boiler, which heats the water inside. When the water temperature of the whole water reaches a critical point where steam is generated to form steam, an internal pressure is formed inside the boiler.

However, in the steam cleaner as described above, the steam is not discharged for a certain time or in a fixed amount during use, so that the internal pressure of the boiler is unstable. In addition, although the boiler continues to be heated, the temperature of the boiler becomes unstable because water is not injected for a certain period of time or in a fixed amount.

Therefore, since the conventional steam cleaner may cause an explosion, it is necessary to adjust the above items and prevent the occurrence of danger when performing the cleaning work.

An object of the present invention is to provide a steam cleaner capable of automatically turning off the power or discharging steam when the pressure in the boiler increases excessively.
