Abstract
This invention relates to steam cleaners for cleaning rugs, upholstery, and the like which comprise (a) a liquids pump, (b) a soap tank adapted to contain a mixture of water and detergent during use of the steam cleaner and having an outlet at the bottom thereof, and (c) means of fluid communication between the outlet at the bottom of the soap tank and the liquids pump. In this case, the invention comprises a screen in inverted-cup-form which is (d) readily pervious to the mixture of water and detergent contained in the soap tank during use of the steam cleaner, (e) impervious to foreign objects such as cigarette butts which may be introduced into the soap tank during use of the steam cleaner, and (f) releasably spring mounted inside the soap tank so as to surround the outlet in the bottom thereof and to filter substantially all of the mixture of water and detergent before it can enter the outlet during use of the steam cleaner, thereby preventing the foreign objects from passing through the means of fluid communication and into the liquids pump. The invention also relates to steam cleaners for rugs, upholstery, and the like which comprise (a) a soap tank adapted to contain a mixture of water and detergent during use of the steam cleaner and (b) an open loop, single turn tubular electrical resistance heating element located in the soap tank for heating the mixture of water and detergent contained in the soap tank during use of the steam cleaner. In this case, the invention comprises a screen which is (c) readily pervious to the mixture of water and detergent contained in the soap tank during use of the steam cleaner, (d) impervious to the fingers of users of the steam cleaner, and (e) mounted inside the soap tank so as to surround the heating element, thereby preventing the fingers of users of the steam cleaner from touching the heating means during use of the steam cleaner. In steam cleaners which comprise the soap tank, the liquids pump, the means of fluid communication, and the heating means, the screen preferably surrounds both the outlet from the soap tank and the heating means. In any event, the screen is preferably releasably mounted in the soap tank so as to facilitate its cleaning and replacement.
