  • Patent number: 10034592
    Abstract: A steam frame for a steam appliance has a body, a passageway in the body for passage of a fluid medium, and a member such as an unbalanced rotatable turbine in fluid communication with the passageway, where the member is capable of being engaged by the fluid medium to produce vibrations in the body for enhanced cleaning performance. A steam attachment includes a body, a pad covering at least a portion of the body, and a heating element coupled to the body. The heating element and vibration-producing member may be used separately or together.

  • Patent number: 9964299
    Abstract: A steam generator includes an inlet configured to receive a liquid (such as water); a heating element for converting the liquid into a vapor (such as steam), the vapor bearing particles such as mineral deposits formed by the converting of the liquid; an outlet in fluid communication with the inlet, the outlet configured to discharge filtered vapor and having a size on the order of larger ones of the particles; and a filter structure adjacent to the outlet to filter the larger particles out of the vapor to produce the filtered vapor for discharge from the outlet. By action of the filter structure, larger particles are prevented from reaching the outlet, reducing clogging and extending the usable lifetime of a small appliance containing the steam generator. The filter structure may include spaced-apart members such as posts or pillars extending perpendicularly in a planar fluid flow passage.

  • Patent number: 9055853
    Abstract: A steam appliance having a split handle with the upper part biased away from the handle base and an actuator for a water pump. When the appliance is pushed, the handle upper part is depressed and displaces a pump actuator to activate the pump. Use of a steam frame and steam towel allows an iron to be used as a steam cleaner. When a pole is mounted on the upper handle part, the appliance may be used as a steam mop that is activated by pushing the pole which depresses the handle to actuate the pump.
